PREFACE 


The  Cornell  University  Nature-Study  propaganda  was  essentially  an 
agricultural  movement  in  its  inception  and  its  aims;  it  was  inaugurated  as 
a direct  aid  to  better  methods  of  agriculture  in  New  York  State.  During 
the  years  of  agricultural  depression  1891-1893,  the  Charities  of  New  York 
City  found  it  necessary  to  help  many  people  who  had  come  from  the  rural 
districts — a condition  hitherto  unknown.  The  philanthropists  managing 
the  Association  for  Improving  the  Condition  of  the  Poor  asked, 
“What  is  the  matter  with  the  land  of  New  York  State  that  it  cannot 
support  its  own  population?”  A conference  was  called  to  consider  the 
situation  to  which  many  people  from  different  parts  of  the  State  were 
invited;  among  them  was  the  author  of  this  book,  who  little  realized  that 
in  attending  that  meeting  the  whole  trend  of  her  activities  would  be  thereby 
changed.  Mr.  George  T.  Powell,  who  had  been  a most  efficient  Director 
of  Farmers’  Institutes  of  New  York  State  was  invited  to  the  conference  as 
an  expert  to  explain  conditions  and  give  advice  as  to  remedies.  The 
situation  seemed  so  serious  that  a Committee  for  the  Promotion  of  Agricul- 
ture in  New  York  State  was  appointed.  Of  this  committee  the  Honorable 
Abram  S.  Hewitt  was  Chairman,  Mr.  R.  Fulton  Cutting,  Treasurer,  Mr. 
Wm.  H.  Tolman,  Secretary.  The  other  members  were  Walter  L.  Suydam, 
Wm.  E.  Dodge,  Jacob  H.  Schiff,  George  T.  Powell,  G.  Howard  Davidson, 
Howard  Townsend,  Professor  I.  P.  Roberts,  C.  McNamee,  Mrs.  J.  R. 
Lowell,  and  Mrs.  A.  B.  Comstock.  Mr.  George  T.  Powell  was  made 
Director  of  the  Department  of  Agricultural  Education. 

At  the  first  meeting  of  this  committee  Mr.  Powell  made  a strong  plea 
for  interesting  the  children  of  the  country  in  farming  as  a remedial  measure, 
and  maintained  that  the  first  step  toward  agriculture  was  nature-study. 
It  had  been  Mr.  Powell’s  custom  to  give  simple  agricultural  and  nature- 
study  instruction  to  the  school  children  of  every  town  where  he  was  con- 
ducting a farmers’  institute,  and  his  opinion  was,  therefore,  based  upon 
experience.  The  committee  desired  to  see  for  itself  the  value  of  this  idea, 
and  experimental  work  was  suggested,  using  the  schools  of  Westchester 
County  as  a laboratory.  Mr.  R.  Fulton  Cutting  generously  furnished  the 
funds  for  this  experiment,  and  work  was  done  that  year  in  the  Westchester 
schools,  which  satisfied  the  committee  of  the  soundness  of  the  project. 

The  committee  naturally  concluded  that  such  a fundamental  movement 
must  be  a public  rather  than  a private  enterprise ; and  Mr.  Frederick  Nixon 
then  Chairman  of  the  Ways  and  Means  Committee  of  the  Assembly, 
was  invited  to  meet  with  the  committee  at  Mr.  Hewitt's  home.  Mr. 
Nixon  had  been  from  the  beginning  of  his  public  career  deeply  interested 
in  improving  the  farming  conditions  of  the  State.  In  1894,  it  was  through

his  influence  and  the  support  given  him  by  the  Chautauqua  Horticultural 
Society  under  the  leadership  of  Mr.  John  W.  Spencer,  that  an  appropriation 
had  been  given  to  Cornell  University  for  promoting  the  horticultural  inter- 
ests of  the  western  counties  of  the  State.  In  addition  to  other  work  done 
through  this  appropriation,  horticultural  schools  were  conducted  under 
the  direction  of  Professor  L.  H.  Bailey  with  the  aid  of  other  Cornell 
instructors  and  especially  of  Mr.  E.  G.  Lodeman;  these  schools  had  proved 
to  be  most  useful  and  were  well  attended.  Therefore,  Mr.  Nixon  was  open- 
minded  toward  an  educational  movement.  He  listened  to  the  plan  of  the 
committee  and  after  due  consideration  declared  that  if  this  new  measure 
would  surely  help  the  farmers  of  the  State,  the  money  would  be  forth- 
coming. The  committee  unanimously  decided  that  if  an  appropriation 
were  made  for  this  purpose  it  should  be  given  to  the  Cornell  College  of 
Agriculture;  and  that  year  eight  thousand  dollars  was  added  to  the  Cornell 
University  Fund,  for  Extension  Teaching  and  inaugurating  this  work.  The 
work  was  begun  under  Professor  I.  P.  Roberts;  after  one  year  Professor 
Roberts  placed  it  under  the  supervision  of  Professor  L.  H.  Bailey,  who  for 
the  fifteen  years  since  has  been  the  inspiring  leader  of  the  movement,  as  well 
as  the  official  head. 

In  1896,  Mr.  John  W.  Spencer,  a fruit  grower  in  Chautauqua  County, 
became  identified  with  the  enterprise;  he  had  lived  in  rural  communities 
and  he  knew  their  needs.  He  it  was  who  first  saw  clearly  that  the  first  step 
in  the  great  work  was  to  help  the  teacher  through  simply  written  leaflets; 
and  later  he  originated  the  great  plan  of  organizing  the  children  in  the 
schools  of  the  State  into  Junior  Naturalists  Clubs,  which  developed  a 
remarkable  phase  of  the  movement.  The  members  of  these  clubs  paid 
their  dues  by  writing  letters  about  their  nature  observations  to  Mr.  Spencer, 
who  speedily  became  their  beloved  ‘‘Uncle  John;”  a button  and  charter 
were  given  for  continued  and  earnest  work.  Some  years,  30,000  children 
were  thus  brought  into  direct  communication  with  Cornell  University 
through  Mr.  Spencer.  A monthly  leaflet  for  Junior  Naturalists  followed; 
and  it  was  to  help  in  this  enterprise  that  Miss  Alice  G.  McCloskey,  the  able 
Editor  of  the  present  Rural  School  Leaflet,  was  brought  into  the  work. 
Later,  Mr.  Spencer  organized  the  children’s  garden  movement  by  forming 
the  children  of  the  State  into  junior  gardeners;  at  one  time  he  had  25,000 
school  pupils  working  in  gardens  and  reporting  to  him. 

In  1899,  Mrs.  Mary  Rogers  Miller,  who  had  proven  a most  efficient 
teacher  when  representing  Cornell  nature-study  in  the  State  Teachers’ 
Institutes,  planned  and  started  the  Home  Nature-Study  Course  Leaflets 
for  the  purpose  of  helping  the  teachers  by  correspondence,  a work  which 
fell  to  the  author  in  1903  when  Mrs.  Miller  was  called  to  other  fields. 

For  the  many  years  during  which  New  York  State  has  intrusted  this 
important  work  to  Cornell  University,  the  teaching  of  nature-study  has

gone  steadily  on  in  the  University,  in  teachers’  institutes,  in  State  summer 
schools,  through  various  publications  and  in  correspondence  courses. 
Many  have  assisted  in  this  work,  notably  Dr.  W.  C.  Thro,  Dr.  A.  A.  Allen, 
and  Miss  Ada  Georgia.  The  New  York  Education  Department  with 
Charles  R.  Skinner  as  Commissioner  of  Education  and  Dr.  Isaac  Stout  as 
the  Director  of  Teachers’  Institutes  co-operated  heartily  with  the  move- 
ment from  the  first.  Later  with  the  co-operation  of  Dr.  Andrew  Draper,  as 
Commissioner  of  Education,  many  of  the  Cornell  leaflets  have  been  written 
with  the  special  purpose  of  aiding  in  carrying  out  the  New  York  State 
Syllabus  in  Nature-Study  and  Agriculture. 

The  leaflets  upon  which  this  volume  is  based  were  published  in  the 
Home  Nature-Study  Course  during  the  years  1903-191 1,  in  limited  editions 
and  were  soon  out  of  print.  It  is  to  make  these  lessons  available  to  the 
general  public  that  this  volume  has  been  compiled.  While  the  subject 
matter  of  the  lessons  herein  given  is  essentially  the  same  as  in  the  leaflets, 
the  lessons  have  all  been  rewritten  for  the  sake  of  consistency,  and  many 
new  lessons  have  been  added  to  bridge  gaps  and  make  a coherent  whole. 

Because  the  lessons  were  written  during  a period  of  so  many  years,  each 
lesson  has  been  prepared  as  if  it  were  the  only  one,  and  without  reference  to 
others.  If  there  is  any  uniformity  of  plan  in  the  lessons,  it  is  due  to  the 
inherent  qualities  of  the  subjects,  and  not  to  a type  plan  in  the  mind  of  the 
writer;  for,  in  her  opinion,  each  subject  should  be  treated  individually  in 
nature-study ; and  in  her  long  experience  as  a nature-study  teacher  she  has 
never  been  able  to  give  a lesson  twice  alike  on  a certain  topic  or  secure 
exactly  the  same  results  twice  in  succession.  It  should  also  be  stated  that 
it  is  not  because  the  author  undervalues  physics  nature-study  that  it  has 
been  left  out  of  these  lessons,  but  because  her  own  work  has  been  always 
along  biological  lines. 

The  reason  why  nature-study  has  not  yet  accomplished  its  mission,  as 
thought-core  for  much  of  the  required  work  in  our  public  schools,  is  that 
the  teachers  are  as  a whole  untrained  in  the  subject.  The  children  are 
eager  for  it,  unless  it  is  spoiled  in  the  teaching;  and  whenever  we  find  a 
teacher  with  an  understanding  of  out-of-door  life  and  a love  for  it,  there  we 
find  nature-study  in  the  school  is  an  inspiration  and  a joy  to  pupils  and 
teacher.  It  is  because  of  the  author’s  sympathy  with  the  untrained  teacher 
and  her  full  comprehension  of  her  difficulties  and  helplessness  that  this  book 
has  been  written.  These  difficulties  are  chiefly  three-fold:  The  teacher 

does  not  know  what  there  is  to  see  in  studying  a plant  or  animal ; she  knows 
little  of  the  literature  that  might  help  her;  and  because  she  knows  so  little 
of  the  subject,  she  has  no  interest  in  giving  a lesson  about  it.  As  a matter 
of  fact,  the  literature  concerning  our  common  animals  and  plants  is  so 
scattered  that  a teacher  would  need  a large  library  and  almost  unlimited 
time  to  prepare  lessons  for  an  extended  nature-study  course. 


VIII 


Handbook  of  Nature-Study 


The  writer’s  special  work  for  fifteen  years  in  Extension  teaching  has  been 
the  helping  of  the  untrained  teacher  through  personal  instruction  and 
through  leaflets.  Many  methods  were  tried  and  finally  there  was  evolved 
the  method  followed  in  this  volume : All  the  facts  available  and  pertinent 
concerning  each  topic  have  been  assembled  in  the  “Teacher’s  story”  to  make 
her  acquainted  with  the  subject;  this  is  followed  by  an  outline  for  observa- 
tion on  the  part  of  the  pupils  while  studying  the  object.  It  would  seem 
that  with  the  teacher’s  story  before  the  eyes  of  the  teacher,  and  the  subject 
of  the  lesson  before  the  eyes  of  the  pupils  with  a number  of  questions  leading 
them  to  see  the  essential  characteristics  of  the  object,  there  should  result  a 
wider  knowledge  of  nature  than  is  given  in  this  or  any  other  book. 

That  the  lessons  are  given  in  a very  informal  manner,  and  that  the  style 
of  writing  is  often  colloquial,  result  from  the  fact  that  the  leaflets  upon 
which  the  book  is  based  were  written  for  a correspondence  course  in  which 
the  communications  were  naturally  informal  and  chatty.  That  the  book 
is  meant  for  those  untrained  in  science  accounts  for  the  rather  loose  termin- 
ology employed;  as,  for  instance,  the  use  of  the  word  seed  in  the  popular 
sense  whether  it  be  a drupe,  an  akene,  or  other  form  of  fruit;  or  the  use  of 
the  word  pod  for  almost  any  seed  envelope,  and  many  like  instances.  Also, 
it  is  very  likely,  that  in  teaching  quite  incidentally  the  rudiments  of  the 
principles  of  evolution,  the  results  may  often  seem  to  be  confused  with  an 
idea  of  purpose,  which  is  quite  unscientific.  But  let  the  critic  labor  for 
fifteen  years  to  interest  the  untrained  adult  mind  in  nature’s  ways,  before  he 
casts  any  stones ! And  it  should  be  always  borne  in  mind  that  if  the  author 
has  not  dipped  deep  in  the  wells  of  science,  she  has  used  only  a child’s  cup. 

For  many  years  requests  have  been  frequent  from  parents  who  have 
wished  to  give  their  children  nature  interests  during  vacations  in  the  coun- 
try. They  have  been  borne  in  mind  in  planning  this  volume;  the  lessons 
are  especially  fitted  for  field  work,  even  though  schoolroom  methods  are 
so  often  suggested. 

The  author  feels  apologetic  that  the  book  is  so  large.  However,  it  does 
not  contain  more  than  any  intelligent  country  child  of  twelve  should  know 
of  his  environment;  things  that  he  should  know  naturally  and  without 
effort,  although  it  might  take  him  half  his  life-time  to  learn  so  much  if  he 
should  not  begin  before  the  age  of  twenty.  That  there  are  inconsistencies, 
inaccuracies,  and  even  blunders  in  the  volume  is  quite  inevitable.  The 
only  excuse  to  be  offered  is  that,  if  through  its  use,  the  children  of  our  land 
learn  early  to  read  nature’s  truths  with  their  own  eyes,  it  will  matter  little 
to  them  what  is  written  in  books. 

The  author  wishes  to  make  grateful  acknowledgment  to  the  following 
people:  To  Professor  Wilford  M.  Wilson  for  his  chapter  on  the  weather; 
to  Miss  Mary  E.  Hill  for  the  lessons  on  mould,  bacteria,  the  minerals,  and 
reading  the  weather  maps;  to  Miss  Catherine  Straith  for  the  lessons  on

PART  1. 


THE  TEACHING  OF  NATURE-STUDY 


WHAT  NATURE-STUDY  IS 

ATURE-STUDY  is,  despite  all  discussions  and  perver- 
sions, a study  of  nature;  it  consists  of  simple,  truthful 
observations  that  may,  like  beads  on  a string,  finally  be 
threaded  upon  the  understanding  and  thus  held  together 
as  a logical  and  harmonious  whole.  Therefore,  the  object 
of  the  nature-study  teacher  should  be  to  cultivate  in  the 
children  powers  of  accurate  observation  and  to  build  up  within  them, 
understanding. 


WHAT  NATURE-STUDY  SHOULD  DO  FOR  THE  CHILD 


IRST,  but  not  most  important,  nature-study  gives  the 
child  practical  and  helpful  knowledge.  It  makes  him 
familiar  with  nature’s  ways  and  forces,  so  that  he  is  not 
so  helpless  in  the  presence  of  natural  misfortune  and 
disasters. 


Nature-study  cultivates  the  child’s  imagination  since  there  are  so 
many  wonderful  and  true  stories  that  he  may  read  with  his  own  eyes, 
which  affect  his  imagination  as  much  as  does  fairy  lore ; at  the  same  time 
nature-study  cultivates  in  him  a perception  and  a regard  for  what  is  true, 
and  the  power  to  express  it.  All  things  seem  possible  in  nature ; yet  this 
seeming  is  always  guarded  by  the  eager  quest  of  what  is  true.  Perhaps, 
half  the  falsehood  in  the  world  is  due  to  lack  of  power  to  detect  the  truth 
and  to  express  it.  Nature-study  aids  both  in  discernment  and  expression 
of  things  as  they  are. 

Nature-study  cultivates  in  the  child  a love  of  the  beautiful;  it  brings 
to  him  early  a perception  of  color,  form  and  music.  He  sees  whatever 
there  is  in  his  environment,  whether  it  be  the  .thunder-head  piled  up  in  the 
western  sky,  or  the  golden  flash  of  the  oriole  in  the  elm ; whether  it  be  the 
purple  of  the  shadows  on  the  snow,  or  the  azure  glint  on  the  wing  of  the 
little  butterfly.  Also,  what  there  is  of  sound,  he  hears;  he  reads  the 
music  score  of  the  bird  orchestra,  separating  each  part  and  knowing 
which  bird  sings  it.  And  the  patter  of  the  rain,  the  gurgle  of  the  brook, 
the  sighing  of  the  wind  in  the  pine,  he  notes  and  loves  and  becomes  en- 
riched thereby. 

But,  more  than  all,  nature-study  gives  the  child  a sense  of  companion- 
ship with  life  out  of  doors  and  an  abiding  love  of  nature.  Let  this  latter 
be  the  teacher’s  criterion  for  judging  his  or  her  work.  If  nature-study  as 
taught  does  not  make  the  child  love  nature  and  the  out-of-doors,  then  it 
should  cease.  Let  us  not  inflict  permanent  injury  on  the  child  by  turning 
him  away  from  nature  instead  of  toward  it.  However,  if  the  love  of 
nature  is  in  the  teacher’s  heart,  there  is  no  danger;  such  a teacher,  no

matter  by  what  method,  takes  the  child  gently  by  the  hand  and  walks 
with  him  in  paths  that  lead  to  the  seeing  and  comprehending  of  what  he 
may  find  beneath  his  feet  or  above  his  head.  And  these  paths  whether 
they  lead  among  the  lowliest  plants,  or  whether  to  the  stars,  finally  con- 
verge and  bring  the  wanderer  to  that  serene  peace  and  hopeful  faith  that 
is  the  sure  inheritance  of  all  those  who  realize  fully  that  they  are 
working  units  of  this  wonderful  universe. 


NATURE-STUDY  AS  A HELP  TO  HEALTH 

ERHAPS  the  most  valuable  practical  lesson  the  child  gets 
from  nature-study  is  a personal  knowledge  that  nature’s 
laws  are  not  to  be  evaded.  Wherever  he  looks,  he  dis- 
covers  that  attempts  at  such  evasion  result  in  suffering 
and  death.  A knowledge  thus  naturally  attained  of  the 
immutability  of  nature’s  “must”  and  “shall  not”  is  in 
itself  a moral  education.  That  the  fool  as  well  as  the  transgressor  fares 
ill  in  breaking  natural  laws,  makes  for  wisdom  in  morals  as  well  as  in 
hygiene. 

Out-of-door  life  takes  the  child  afield  and  keeps  him  in  the  open  air, 
which  not  only  helps  him  physically  and  occupies  his  mind  with  sane 
subjects,  but  keeps  him  out  of  mischief.  It  is  not  only  during  childhood 
that  this  is  true,  for  love  of  nature  counts  much  for  sanity  in  later  life. 
This  is  an  age  of  nerve  tension,  and  the  relaxation  which  comes  from  the 
comforting  companionship  found  in  woods  and  fields  is,  without  doubt, 
the  best  remedy  for  this  condition.  Too  many  men  wTho  seek  the  out-of- 
doors  for  rest  at  the  present  time,  can  only  find  it  with  a gun  in  hand.  To 
rest  and  heal  their  nerves  they  must  go  out  and  try  to  kill  some  unfor- 
tunate creature, — the  old,  old  story  of  sacrificial  blood.  Far  better  will  it 
be  when,  through  properly  training  the  child,  the  man  shall  be  enabled  to 
enjoy  nature  through  seeing  how  creatures  live  rather  than  watching 
them  die.  It  is  the  sacred  privilege  of  nature-study  to  do  this  for  future 
generations  and  for  him  thus  trained,  shall  the  words  of  Longfellow’s 
poem  to  Agassiz  apply : 

“ And  he  wandered  away  and  away,  with  Nature  the  dear  old  nurse, 

Who  sang  to  him  night  and  day,  the  rhymes  of  the  universe. 

And  when  the  way  seemed  long,  and  his  heart  began  to  fail. 

She  sang  a more  wonderful  song,  or  told  a more  wonderful  tale.” 


WHAT  NATURE-STUDY  SHOULD  DO  FOR  THE  TEACHER 


URING  many  years,  I have  been  watching  teachers  in  our 
public  schools  in  their  conscientious  and  ceaseless  work; 
and  so  far  as  I can  foretell,  the  fate  that  awaits  them 
finally  is  either  nerve  exhaustion  or  nerve  atrophy. 
The  "teacher  must  become  either  a neurasthenic  or  a 
“clam.” 


I have  had  conversations  with  hundreds  of  teachers  in  the  public 
schools  of  New  York  State  concerning  the  introduction  of  nature-study 
into  the  curriculum,  and  most  of  them  declared,  “Oh,  we  have  not  time 
for  it.  Every  moment  is  full  now!”  Their  nerves  were  at  such  a tension 
that  with  one  more  thing  to  do  they  must  fall  apart.  The  question  in 
my  own  mind  during  these  conversations  was  always,  how  long  can  she 


The  Teaching  of  N atur e-Study

stand  it ! I asked  some  of  them  “Did  you  ever  try  a vigorous  walk  in  the 
open  air  in  the  open  country  every  Saturday  or  every  Sunday  of  your 
teaching  year?”  “Oh  no!”  they  exclaimed  in  despair  of  making  me 
understand.  “On  Sunday  we  must  go  to  church  or  see  our  friends  and  on 
Saturday  we  must  do  our  shopping  or  our  sewing.  We  must  go  to  the 
dressmaker’s  lest  we  go  unclad,  we  must  mend,  and  darn  stockings;  we 
need  Saturday  to  catch  up.” 

Yes,  catch  up  with  more  cares,  more  worries,  more  fatigue,  but  not 
with  more  growth,  more  strength,  more  vigor  and  more  courage  for  work. 
In  my  belief,  there  are  two  and  only  two  occupations  for  Saturday  after- 
noon or  forenoon  for  a teacher.  One  is  to  be  out  of  doors  and  the  other  is 
to  lie  in  bed,  and  the  first  is  best.  Out  in  this,  God’s  beautiful  world, 
there  is  everything  waiting  to  heal  lacerated  nerves,  to  strengthen  tired 
muscles,  to  please  and  content  the  soul  that  is  torn  to  shreds  with  duty 
and  care.  To  the  teacher  who  turns  to  nature’s  healing,  nature-study  in 
the  schoolroom  is  not  a trouble;  it  is  a sweet,  fresh  breath  of  air  blown 
across  the  heat  of  radiators  and  the  noisome  odor  of  over-crowded  small 
humanity.  She,  who  opens  her  eyes  and  her  heart  nature-ward  even  once 
a week,  finds  nature-study  in  the  schoolroom  a delight  and  an  abiding  joy. 
What  does  such  a one  find  in  her  schoolroom  instead  of  the  terrors  of 
discipline,  the  eternal  watching  and  eternal  nagging  to  keep  the  pupils 
quiet  and  at  work?  She  finds,  first  of  all,  companionship  with  her 
children;  and  second,  she  finds  that  without  planning  or  going  on  a far 
voyage,  she  has  found  health  and  strength. 

WHEN  AND  WHY  THE  TEACHER  SHOULD  SAY  “i  DO  NOT  KNOW” 

m O SCIENCE  professor  in  any  university,  if  he  be  a man  of 
1\  high  attainment,  hesitates  to  say  to  his  pupils  “I  do 

I \ L*#>  not  know,”  if  they  ask  for  information  beyond  his 

I knowledge.  The  greater  his  scientific  reputation  and 

^ erudition,  the  more  readily,  simply  and  without  apology 

he  says  this.  He,  better  than  others,  comprehends  how 
vast  is  the  region  that  lies  beyond  man’s  present  knowledge.  It  is 
only  the  teacher  in  the  elementary  schools  who  has  never  received 
enough  scientific  training  to  reveal  to  her  how  little  she  does  know,  who 
feels  that  she  must  appear  to  know  everything  or  her  pupils  will  lose 
confidence  in  her.  But  how  useless  is  this  pretence,  in  nature-study  ! 
The  pupils,  whose  younger  eyes  are  much  keener  for  details  than  hers, 
will  soon  discover  her  limitations  and  then  their  distrust  of  her  will  be 
real. 

In  nature-study  any  teacher  can  with  honor  say,  “I  do  not  know;”  for 
perhaps,  the  question  asked  is  as  yet  unanswered  by  the  great  scientists. 
But  she  should  not  let  her  lack  of  knowledge  be  a wet  blanket  thrown  over 
her  pupils’  interest.  She  should  say  frankly,  “I  do  not  know;  let  us  see 
if  we  cannot  together  find  out  this  mysterious  thing.  Maybe  no  one 
knows  it  as  yet,  and  I wonder  if  you  will  discover  it  before  I do.”  She 
thus  conveys  the  right  impression,  that  only  a little  about  the  intricate 
life  of  plants  and  animals  is  yet  known ; and  at  the  same  time  she  makes 
her  pupils  feel  the  thrill  and  zest  of  investigation.  Nor  will  she  lose  their 
respect  by  doing  this,  if  she  does  it  in  the  right  spirit.  For  three  years,  I 
had  for  comrades  in  my  walks  afield,  two  little  children  and  they  kept  me 


4 


Handbook  of  Nature-Study 


busy  saying,  “ I do  not  know’  ’ . But  they  never  lost  confidence  in  me  or  in 
my  knowledge;  they  simply  gained  respect  for  the  vastness  of  the  un- 
known. 

The  chief  charm  of  nature-study  would  be  taken  away  if  it  did  not  lead 
us  through  the  border-land  of  knowledge  into  the  realm  of  the  undiscovered. 
Moreover,  the  teacher,  in  confessing  her  ignorance  and  at  the  same  time 
her  interest  in  a subject,  establishes  between  herself  and  her  pupils  a sense 
of  companionship  which  relieves  the  strain  of  discipline,  and  gives  her  a 
new  and  intimate  relation  with  her  pupils  which  will  surely  prove  a 
potent  element  in  her  success.  The  best  teacher  is  always  one  who  is  the 
good  comrade  of  her  pupils. 

NATURE-STUDY,  THE  ELIXIR  OF  YOUTH 

HE  old  teacher  is  too  likely  to  become  didactic,  dogmatic 
and  “bossy”  if  she  does  not  constantly  strive  with  herself. 
Why?  She  has  to  be  thus  five  days  in  the  week  and, 
therefore,  she  is  likely  to  be  so  seven.  She  knows  arith- 
metic, grammar  and  geography  to  their  uttermost  and 
she  is  never  allowed  to  forget  that  she  knows  them, 
and  finally  her  interests  become  limited  to  what  she  knows. 

After  all,  what  is  the  chief  sign  of  growing  old?  Is  it  not  the  feeling 
that  we  know  all  there  is  to  be  known  ? It  is  not  years  which  make  people 
old;  it  is  ruts,  and  a limitation  of  interests.  When  we  no  longer  care 
about  anything  except  our  own  interests,  we  are  then  old,  it  matters  not 
whether  our  years  be  twenty  or  eighty.  It  is  rejuvenation  for  the 
teacher,  thus  growing  old,  to  stand  ignorant  as  a child  in  the  presence  of 
one  of  the  simplest  of  nature’s  miracles — the  formation  of  a crystal,  the 
evolution  of  the  butterfly  from  the  caterpillar,  the  exquisite  adjustment 
of  the  silken  lines  in  the  spider’s  orb-web.  I know  how  to  “make  magic” 
for  the  teacher  who  is  growing  old.  Let  her  go  out  with  her  youngest 
pupil  and  fall  on  her  knees  before  the  miracle  of  the  blossoming  violet  and 
say:  “Dear  Nature,  I know  naught  of  the  wondrous  life  of  these,  your 

smallest  creatures.  Teach  me !”  and  she  will  suddenly  find  herself  young. 

NATURE-STUDY  AS  A HELP  IN  SCHOOL  DISCIPLINE 

_ jflf  UCH  of  the  naughtiness  in  school  is  a result  of  the  child’s 
lack  of  interest  in  his  work,  augmented  by  the  physical 
inaction  that  results  from  an  attempt  to  sit  quietly.  The 
1^1  best  teachers  try  to  obviate  both  of  these  rather  than  to 
V ^ punish  because  of  them.  Nature-study  is  an  aid  in  both 
respects,  since  it  keeps  the  child  interested  and  also  gives  him  something 
to  do. 

In  the  nearest  approach  to  an  ideal  school  that  I have  ever  seen,  for 
children  of  second  grade,  the  pupils  were  allowed,  as  a reward  of  merit,  to 
visit  the  aquaria  or  the  terrarium  for  periods  of  five  minutes,  which  time 
was  given  to  the  blissful  observation  of  the  fascinating  prisoners.  The 
teacher  also  allowed  the  reading  of  stories  about  the  plants  and  animals 
under  observation  to  be  regarded  as  a reward  of  merit.  As  I entered  the 
schoolroom,  there  were  eight  or  ten  of  the  children  at  the  windows  watch- 
ing eagerly  what  was  happening  to  the  creatures  confined  there  in  the 
various  cages.  There  was  a mud  aquarium  for  the  frogs  and  salamanders, 


The  Teaching  of  Nature-Study

an  aquarium  for  fish,  many  small  aquaria  for  insects  and  each  had  one  or 
two  absorbingly  interested  spectators  who  were  quiet,  well  behaved  and 
were  getting  their  nature-study  lessons  in  an  ideal  manner.  The  teacher 
told  me  that  the  problem  of  discipline  was  solved  by  this  method,  and 
that  she  was  rarely  obliged  to  rebuke  or  punish.  In  many  other  schools, 
watching  the  living  creatures  in  the  aquaria,  or  terrarium  has  been  used 
as  a reward  for  other  work  well  done. 

THE  RELATION  OF  NATURE-STUDY  TO  SCIENCE 

ATURE-STUDY  is  not  elementary  science  as  so  taught, 
I Safe . because  its  point  of  attack  is  not  the  same ; error  in  this 
tlMli1/  respect  has  caused  many  a teacher  to  abandon  nature- 
study  and  many  a pupil  to  hate  it.  In  elementary  science 
work  begins  with  the  simplest  animals  and  plants 
and  progresses  logically  through  to  the  highest  forms ; at 
least  this  is  the  method  pursued  in  most  universities  and 
schools.  The  object  of  the  study  is  to  give  the  pupils  an  outlook  over 
all  the  forms  of  life  and  their  relation  one  to  another.  In  nature-study 
the  work  begins  with  any  plant  or  creature  which  chances  to  interest  the 
pupil.  It  begins  with  the  robin  when  it  comes  back  to  us  in  March, 
promising  spring;  or  it  begins  with  the  maple  leaf  which  flutters  to  the 
ground  in  all  the  beauty  of  its  autumnal  tints.  A course  in  biological 
science  leads  to  the  comprehension  of  all  kinds  of  life  upon  our  globe. 
Nature-study  is  for  the  comprehension  of  the  individual  life  of  the 
bird,  insect  or  plant  that  is  nearest  at  hand. 

Nature-study  is  perfectly  good  science  within  its  limits,  but  it  is  not 
meant  to  be  more  profound  or  comprehensive  than  the  capabilities  of  the 
child’s  mind.  More  than  all,  nature-study  is  not  science  belittled  as  if 
it  were  to  be  looked  at  through  the  reversed  opera  glass  in  order  to  bring 
it  down  small  enough  for  the  child  to  play  with.  Nature-study,  as  far  as 
it  goes,  is  just  as  large  as  is  science  for  “grown-ups”  and  may  deal  with  the 
same  subject  matter  and  should  be  characterized  by  the  same  accuracy. 
It  simply  does  not  go  so  far. 

To  illustrate : If  we  are  teaching  the  science  of  ornithology,  we  take 

first  the  Archaeopteryx,  then  the  swimming  and  the  scratching  birds  and 
finally  reach  the  song  birds,  studying  each  as  a part  of  the  whole.  Nature- 
study  begins  with  the  robin  because  the  child  sees  it  and  is  interested  in  it 
and  he  notes  the  things  about  the  habits  and  appearance  of  the  robin  that 
may  be  perceived  by  intimate  observation.  In  fact,  he  discovers  for  him- 
self all  that  the  most  advanced  book  of  ornithology  would  give  concerning 
the  ordinary  habits  of  this  one  bird;  the  next  bird  studied  may  be  the 
turkey  in  the  barnyard,  or  the  duck  on  the  pond,  or  the  screech-owl  in  the 
spruces,  if  any  of  these  happen  to  impinge  upon  his  notice  and  interest. 
However,  such  nature-study  makes  for  the  best  of  scientific  ornithology, 
because  by  studying  the  individual  birds  thus  thoroughly,  the  pupil 
finally  studies  a sufficient  number  of  forms  so  that  his  knowledge,  thus 
assembled,  gives  him  a better  comprehension  of  birds  as  a whole  than 
could  be  obtained  by  the  routine  study  of  the  same.  Nature-study  does 
not  start  out  with  the  classification  given  in  books,  but  in  the  end  it  builds 
up  a classification  in  the  child’s  mind  which  is  based  on  fundamental 
knowledge;  it  is  a classification  like  that  evolved  by  the  first  naturalists, 
it  is  built  on  careful  personal  observations  of  both  form  and  life.

NATURE-STUDY  NOT  FOR  DRILL 

If  nature-study  is  made  a drill,  its  pedagogic  value  is  lost.  When  it 
is  properly  taught,  the  child  is  unconscious  of  mental  effort  or  that  he 
is  suffering  the  act  of  teaching.  As  soon  as  nature-study  becomes  a 
task,  it  should  be  dropped;  but  how  could  it  ever  be  a task  to  see  that 
the  sky  is  blue,  or  the  dandelion  golden,  or  to  listen  to  the  oriole  in  the 
elm! 

THE  CHILD  NOT  INTERESTED  IN  NATURE-STUDY 

HAT  to  do  with  the  pupil  not  interested  in  nat- 
ure-study subjects  is  a problem  that  confronts 
many  earnest  teachers.  Usually  the  reason  for 
this  lack  of  interest,  is  the  limited  range  of  sub- 
jects-used  for  nature-study  lessons.  Often  the 
teacher  insists  upon  flowers  as  the  lesson 
subject,  when  toads  or  snakes  would  prove 
the  key  to  the  door  of  the  child’s  interest. 
But  whatever  the  cause  may  be,  there  is  only 
one  right  way  out  of  this  difficulty : The  child 

not  interested  should  be  kept  at  his  regular 
school  work  and  not  admitted  as  a member 
of  the  nature-study  class,  where  his  influence 
is  always  demoralizing.  He  had  much  bet- 
ter be  learning  his  spelling  lesson  than  learn- 
ing to  hate  nature  through  being  obliged  to 
study  subjects  in  which  he  is  not  interested.  In  general,  it  is  safe  to 
assume  that  the  pupil’s  lack  of  interest  in  nature-study  is  owing  to  a fault 
in  the  teacher’s  method.  She  may  be  trying  to  fill  the  child’s  mind 
with  facts  when  she  should  be  leading  him  to  observe  these  for  himself, 
which  is  a most  entertaining  occupation  for  the  child.  It  should  always 
be  borne  in  mind  that  mere  curiosity  is  always  impertinent,  and  that  it 
is  never  more  so  than  when  exercised  in  the  realm  of  nature.  A genuine 
interest  should  be  the  basis  of  the  study  of  the  lives  of  plants  and  lower 
animals.  Curiosity  may  elicit  facts,  but  only  real  interest  may  mold  these 
facts  into  wisdom. 


WHEN  TO  GIVE  THE  LESSON 

HERE  are  two  theories  concerning  the  time  when  a nature- 
study  lesson  should  be  given.  Some  teachers  believe 
that  it  should  be  a part  of  the  regular  routine;  others 
have  found  it  of  greatest  value  if  reserved  for  that  period 
of  the  school  day  when  the  pupils  are  weary  and  restless, 
and  the  teacher’s  nerves  strained  to  the  snapping  point. 
The  lesson  on  a tree,  insect  or  flower  at  such  a moment  affords  immedi- 
ate relief  to  everyone;  it  is  a mental  excursion,  from  which  all  return 
refreshed  and  ready  to  finish  the  duties  of  the  day. 

While  I am  convinced  that  the  use  of  the  nature-study  lesson  for 
mental  refreshment  makes  it  of  greatest  value,  yet  I realize  fully  that  if  it 
is  relegated  to  such  perio.ds,  it  may  not  be  given  at  all.  It  might  be 
better  to  give  it  a regular  period  late  in  the  day,  for  there  is  strength  and 
sureness  in  regularity.  The  teacher  is  much  more  likely  to  prepare  her- 
self for  the  lesson,  if  she  knows  that  it  is  required  at  a certain  time.

THE  LENGTH  OF  THE  LESSON 

^fffJTlKRE  nature-study  lesson  should  be  short  and  sharp  and  may 
vary  from  ten  minutes  to  a half  hour  in  length.  There 
should  be  no  dawdling;  if  it  is  an  observation  lesson,  only 
a few  points  should  be  noted  and  the  meaning  for  the  ob- 
servations  made  clear.  If  an  outline  be  suggested  for 
field  observation,  it  should  be  given  in  an  inspiring  man- 
ner which  shall  make  each  pupil  anxious  to  see  and  read  the  truth  for 
himself.  The  nature  story  when  properly  read  is  never  finished ; it  is 
always  at  an  interesting  point,  “continued  in  our  next.” 

The  teacher  may  judge  as  to  her  own  progress  in  nature-study  by  the 
length  of  time  she  is  glad  to  spend  in  reading  from  nature’s  book  what  is 
therein  written.  As  she  progresses,  she  finds  those  hours  spent  in  study- 
ing nature  speed  faster,  until  a day  thus  spent  seems  but  an  hour.  The 
author  can  think  of  nothing  she  would  so  gladly  do  as  to  spend  days  and 
months  with  the  birds,  bees  and  flowers  with  no  obligation  for  telling 
what  she  should  see.  There  is  more  than  mere  information  in  hours  thus 
spent.  Lowell  describes  them  well  when  he  says : 

“Those  old  days  when  the  balancing  of  a yellow  butterfly  o'er  a thistle  bloom 
Was  spiritual  food  and  lodging  for  the  whole  afternoon." 

THE  NATURE-STUDY  LESSON  ALWAYS  NEW 

A nature-study  lesson  should  not  be  repeated  unless  the  pupils 
demand  it.  It  should  be  done  so  well  the  first  time  that  there  is  no  need 
of  repetition,  because  it  has  thus  become  a part  of  the  child’s  conscious- 
ness. The  repetition  of  the  same  lesson  in  different  grades  was,  to  begin 
with,  a hopeless  incubus  upon  nature-study.  One  disgusted  boy  declared, 
“Darn  germination ! I had  it  in  the  primary  and  last  year  and  now  I am 
having  it  again.  I know  all  about  germination. ” The  boy’s  attitude  was 
a just  one ; but  if  there  had  been  revealed  to  him  the  meaning  of  germina- 
tion, instead  of  the  mere  process,  he  would  have  realized  that  until  he  had 
planted  and  observed  every  plant  in  the  world  he  would  not  know  all 
about  germination,  because  each  seedling  has  its  own  interesting  story. 
The  only  excuse  for  repeating  a nature-study  lesson  is  in  recalling  it  for 
comparison  and  contrast  with  other  lessons.  The  study  of  the  violet  will 
naturally  bring  about  a review  of  the  pansy;  the  dandelion,  of  the  sun- 
flower; the  horse,  of  the  donkey;  the  butterfly,  of  the  moth. 

NATURE-STUDY  AND  OBJECT  LESSONS 

HE  object  lesson  method  was  introduced  to  drill  the  child 
to  see  a thing  accurately,  not  only  as  a whole,  but  in 
detail  and  to  describe  accurately  what  he  saw.  A book 
or  a vase  or  some  other  object  was  held  up  before  the  class 
for  a moment  and  then  removed ; afterwards  the  pupils 
described  it  as  perfectly  as  possible.  This  is  an  excellent 
exercise  and  the  children  usually  enjoy  it  as  if  it  were  a 
game.  But  if  the  teacher  has  in  mind  the  same  thought  when  she  is  giv- 
ing the  nature-study  lesson,  she  has  little  comprehension  of  the  meaning 
of  the  latter  and  the  pupils  will  have  less.  In  nature-study,  it  is  not  de- 
sirable that  the  child  see  all  the  details,  but  rather  those  details  that  have 
something  to  do  with  the  life  of  the  creature  studied ; if  he  sees  that  the 


& 


Handbook  of  Nature-Study 


grasshopper  has  the  hind  legs  much  longer  than  the  others,  he  will  inev- 
itably note  that  there  are  two  other  pairs  of  legs  and  he  will  in  the 
meantime  have  come  into  an  illuminating  comprehension  of  the  reason 
the  insect  is  called  “grasshopper.”  The  child  should  see  definitely  and 
accurately  all  that  is  necessary  for  the  recognition  of  a plant  or  animal; 
but  in  nature-study,  the  observation  of  form  is  for  the  purpose  of  better 
understanding  life.  In  fact,  it  is  form  linked  with  life,  the  relation  of 
“being”  to  “doing.” 


NATURE-STUDY  IN  THE  SCHOOLROOM 

ANY  subjects  for  nature-study  lessons  may  be  brought 
into  the  schoolroom.  Whenever  it  is  possible,  the  pupils 
should  themselves  bring  the  material,  as  the  collecting 
of  it  is  an  important  part  of  the  lesson.  There  should 
be  in  the  schoolroom  conveniences  for  caring  for  the 
little  prisoners  brought  in  from  thefield.  The  terrarium 
and  breeding  cages,  of  different  kinds  should  be  pro- 
vided for  the  insects,  toads  and  little  mammals.  Here  they  may  live 
in  comfort,  when  given  their  natural  food,  while  the  children  observe 
their  interesting  ways.  The  ants’  nest,  and  the  observation  hive  yield 
fascinating  views  of  the  marvelous  lives  of  the  insect  socialists,  while  the 
cheerful  prisoner  in  the  bird  cage  may  be  made  a constant  illustration  of 
the  adaptations  and  habits  of  all  birds.  The  aquaria  for  fishes,  tadpoles 
and  insects  afford  the  opportunity  for  continuous  study  of  these  water 
creatures  and  are  a never-failing  source  of  interest  to  the  pupils,  while 
the  window  garden  may  be  made  not  only  an  ornament  and  an  aesthetic 
delight,  but  a basis  for  interesting  study  of  plant  growth  and  development. 

A schoolroom  thus  equipped  is  a place  of  delight  as  well  as  enlighten- 
ment to  the  children.  Once,  a boy  whose  luxurious  home  was  filled  with 
all  that  money  could  buy  and  educated  tastes  select,  said  of  a little  nature- 
study  laboratory  which  was  in  the  unfinished  attic  of  a school  building,  but 
which  was  teeming  with  life : “I  think  this  is  the  most  beautiful  room  in 

the  world.” 

NATURE-STUDY  AND  MUSEUM  SPECIMENS 

HE  matter  of  museum  specimens  is  another  question  for 
the  nature-study  teacher  to  solve,  and  has  a direct 
bearing  on  an  attitude  toward  taking  life.  There  are 
many  who  believe  the  stuffed  bird  or  the  case  of  pinned 
insects  have  no  place  in  nature-study;  and  certainly 
these  should  not  be  the  chief  material.  But  let  us  use 
our  common  sense ; the  boy  sees  a bird  in  the  woods  or 
field  and  does  not  know  its  name ; he  seeks  the  bird  in  the  museum  and 
thus  is  able  to  place  it  and  read  about  it  and  is  stimulated  to  make  other 
observations  concerning  it.  Wherever  the  museum  is  a help  to  the  study 
of  life  in  the  field,  it  is  well  and  good.  Some  teachers  may  give  a live  les- 
son from  a stuffed  specimen,  and  other  teachers  may  stuff  their  pupils 
with  facts  about  a live  specimen;  of  the  two,  the  former  is  preferable. 

There  is  no  question  that  making  a collection  of  insects  is  an 
efficient  way  of  developing  the  child’s  powers  of  close  observation,  as  well 
as  of  giving  him  manual  dexterity  in  handling  fragile  things..  Also  it  is 
a false  sentiment  which  attributes  to  an  insect  the  same  agony  at  being 


The  Teaching  of  Nature-Study

impaled  on  a pin  that  we  might  suffer  at  being  thrust  through  by  a stake. 
The  insect  nervous  system  is  far  more  conveniently  arranged  for  such  an 
ordeal  than  ours;  and,  too,  the  cyanide  bottle  brings  immediate  and  pain- 
less death  to  the  insects  placed  within  it;  moreover,  the  insects  usually 
collected  have  short  lives  anyway.  So  far  as  the  child  is  concerned,  he  is 
thinking  of  his  collection  of  moths  or  butterflies  and  not  at  all  of  taking 
life;  so  it  is  not  teaching  him  to  wantonly  destroy  living  creatures. 
However,  an  indiscriminate  encouragement  of  the  making  of  insect  col- 
lections cannot  be  advised.  There  are  some  children  who  will  profit  by  it 
and  some  who  will  not,  and  unquestionably  the  best  kind  of  study  of 
insects  is  watching  their  interesting  ways  while  they  live. 

To  kill  a creature  in  order  to  prepare  it  for  a nature-study  lesson  is  not 
only  wrong  but  absurd,  for  nature-study  has  to  do  with  life  rather  than 
death,  and  the  form  of  any  creature  is  interesting  only  when  its  adapta- 
tions for  life  are  studied.  But  again,  a nature-study  teacher  may  be  an 
opportunist  ; if  without  any  volition  on  her  part  or  the  pupils’,  a freshly 
killed  specimen  comes  to  hand,  she  should  make  the  most  of  it.  The 
writer  remembers  most  illuminating  lessons  from  a partridge  that  broke 
a window  and  its  neck  simultaneously  during  its  flight  one  winter  night, 
a yellow  hammer  that  killed  itself  against  an  electric  wire,  and  a muskrat 
that  turned  its  toes  to  the  skies  for  no  understandable  reason.  In  each  of 
these  cases  the  creature’s  special  physical  adaptations  for  living  its  own 
peculiar  life  were  studied,  and  the  effect  was  not  the  study  of  a dead 
thing,  but  of  a successful  and  wonderful  life. 

THE  LENS,  MICROSCOPE  AND  FIELD  GLASS  AS  HELPS  IN  NATURE-STUDY 

JN  elementary  grades,  nature-study  deals  with  objects  which 
the  children  can  see  with  the  naked  eye.  However,  a lens 
is  a help  in  almost  all  of  this  work  because  it  is  such  a joy 
to  the  child  to  gaze  at  the  wonders  it  reveals.  There  is  no 
.g  lesson  given  in  this  book  which  requires  more  than  a simple 

lens  for  seeing  the  most  minute  parts  discussed.  An  ex- 
cellent lens  may  be  bought  for  a dollar,  and  a fairly  good  one  for  fifty 
cents  or  even  twenty-five  cents.  The  lens  should  be  chained  to  a table 
or  desk  where  it  may  be  used  by  the  pupils  at  recess.  This  gives  each 
an  opportunity  for  using  it  and  obviates  the  danger  of  losing  it.  If 
the  pupils  themselves  own  lenses,  they  should  be  fastened  by  a string  or 
chain  to  the  pocket. 

A microscope  has  no  legitimate  part  in  nature-study.  But  if  there  is 
one  available,  it  reveals  so  many  wonders  in  the  commonest  objects,  that 
it  can  be  made  a source  of  added  interest  ofttimes.  For  instance,  to  thus 
see  the  scales  on  the  butterfly’s  wing  affords  the  child  pleasure  as  well  as 
edification.  Field  or  opera  glasses,  while  indispensible  for  bird  study,  are 
by  no  means  necessary  in  nature-study.  However,  the  pupils  will  show 
greater  interest  in  noting  the  birds’  colots  if  they  are  allowed  to  make  the 
observations  with  the  help  of  a glass.

USES  OF  PICTURES,  CHARTS  AND  BLACKBOARD  DRAWINGS 

ICTURES  alone  should  never  be  used  as  the  subjects  for 
nature-study  lessons,  but  they  may  be  of  great  use  in 
illustrating  and  illuminating  a lesson.  Books  well  illus- 
trated are  more  readily  comprehended  by  the  child  and 
are  often  very  helpful  to  him,  especially  after  his  interest 
in  the  subject  is  thoroughly  aroused.  If  charts  are  used 
to  illustrate  the  lesson,  the  child  is  likely  to  be  misled  by  the  size  of  the 
drawing,  which  is  also  the  case  in  blackboard  pictures.  However,  this 
error  may  be  avoided  by  fixing  the  attention  of  the  pupil  on  the  object 
first.  If  the  pupils  are  studying  the  ladybird  and  have  it  in  their  hands, 
the  teacher  may  use  a diagram  representing  the  beetle  as  a foot  long  and 
it  will  still  convey  the  idea  accurately ; but  if  she  begins  with  the  pict- 
ure, she  probably  can  never  convince  the  children  that  the  picture  has 
anything  to  do  with  the  insect. 

In  making  blackboard  drawings  illustrative  of  the  lesson,  it  is  best,  if 
possible,  to  have  one  of  the  pupils  do  the  drawing  in  the  presence  of  the 
class;  or,  if  the  teacher  does  the  drawing,  she  should  hold  the  object  in 
her  hand  while  doing  it  and  look  at  it  often  so  that  the  children  may 
see  that  she  is  trying  to  represent  it  accurately.  Taking  everything  into 
consideration,  however,  nature-study  charts  and  blackboard  drawings  are 
of  little  use  to  the  nature-study  teacher. 


THE  USES  OF  SCIENTIFIC  NAMES 

ISQUIETING  problems  relative  to  scientific  nomenclature 
always  confront  the  teacher  of  nature-study.  My  own 
practice  has  been  to  use  the  popular  names  of  species, 
except  in  cases  where  confusion  might  ensue,  and  to  use 
the  scientific  names  for  anatomical  parts.  However, 
this  matter  is  of  little  importance  if  the  teacher  bears  in 
mind  that  the  purpose  of  nature-study  is  to  know  the  subject  under  obser- 
vation and  to  learn  the  name  incidentally. 

If  the  teacher  says : “I  have  a pink  hepatica.  Can  anyone  find  me  a 

blue  one?”  the  children,  who  naturally  like  grown-up  words,  will  soon  be 
calling  these  flowers  hepaticas.  But  if  the  teacher  says,  “These  flowers 
are  called  hepaticas.  Now  please  everyone  remember  the  name.  Write 
it  in  your  books  as  I write  it  on  the  blackboard,  and  in  half  an  hour  I shall 
ask  you  again  what  it  is,”  the  pupils  naturally  look  upon  the  exercise  as  a 
word  lesson  and  its  real  significance  is  lost.  This  sort  of  nature-study  is 
dust  and  ashes  and  there  has  been  too  much  of  it.  The  child  should  never 
be  required  to  learn  the  name  of  anything  in  the  nature-study  work ; but 
the  name  should  be  used  so  often  and  so  naturally  in  his  presence,  that 
he  will  learn  it  without  being  conscious  of  the  process. 


THE  STORY  AS  A SUPPLEMENT  TO  THE  NATURE-STUDY  LESSON 


ANY  of  the  subjects  for  nature  lessons  can  be  studied  only 
in  part,  since  but  one  phase  may  be  available  at  the 
time.  Often,  especially  if  there  is  little  probability  that 
the  pupils  will  find  opportunity  to  complete  the  study,  it 
is  best  to  round  out  their  knowledge  by  reading  or  telling 
the  story  to  supplement  the  facts  which  they  have  discov- 


The  Teaching  of  Nature-Study 


ii 


ered  for  themselves.  This  story  should  not  be  told  as  a finality  or  as  a 
complete  picture  but  as  a guide  and  inspiration  for  further  study.  Always 
leave  at  the  end  of  the  story  an  interrogation  mark  that  will  remain  ag- 
gressive and  insistent  in  the  child’s  mind.  To  illustrate:  Once  a club 

of  junior  naturalists  brought  me  rose  leaves  injured  by  the  leaf-cutter 
bee  and  asked  me  why  the  leaves  were  cut  out  so  regularly.  I told 
them  the  story  of  the  use  made  by  the  mother  bee  of  these  oval  and  cir- 
cular bits  of  leaves  and  made  the  account  as  vital  as  I was  able ; but  at 
the  end  I said,  “I  do  not  know  which  species  of  bee  cut  these  leaves. 
She  is  living  here  among  us  and  building  her  nest  with  your  rose  leaves 
which  she  is  cutting  every  day  almost  under  your  very  eyes.  Is  she 
then  so  much  more  clever  than  you  that  you  cannot  see  her  nor  find  her 
nest?”  For  two  years  following  this  lesson  I received  letters  from  mem- 
bers of  this  club.  Two  carpenter  bees  and  their  nests  were  discovered  by 
them  and  studied  before  the  mysterious  leaf-cutter  was  finally  ferreted 
out.  My  story  had  left  something  interesting  for  the  young  naturalists 
to  discover.  The  children  should  be  impressed  with  the  fact  that  the 
nature  story  is  never  finished.  There  is  not  a weed  nor  an  insect  nor  a 
tree  so  common  that  the  child,  by  observing  carefully,  may  not  see  things 
never  yet  recorded  in  scientific  books;  therefore  the  supplementary  story 
should  be  made  an  inspiration  for  keener  interest  and  further  investi- 
gation on  the  part  of  the  pupil.  The  supplementary  story  simply  thrusts 
aside  some  of  the  obscuring  underbrush  thus  revealing  more  plainly  the 
path  to  further  knowledge. 


THE  NATURE-STUDY  ATTITUDE  TOWARD  LIFE  AND  DEATH 

ERHAPS  no  greater  danger  besets  the  pathway  of  the 
nature-study  teacher  than  the  question  involved  in  her 
pupils’  attitude  toward  life  and  death.  To  inculcate  in 
the  child  a reverence  for  life  and  yet  to  keep  him  from 
becoming  mawkish  and  morbid  is  truly  a problem.  It 
is  almost  inevitable  that  the  child  should  become  sym- 
pathetic with  the  life  of  the  animal  or  plant  studied, 
since  a true  understanding  of  the  life  of  any  creature 
creates  an  interest  which  stimulates  a desire  to  protect  this  particular 
creature  and  make  its  life  less  hard.  Many  times,  within  my  own  ex- 
perience, have  I known  boys,  who  began  by  robbing  birds’  nests  for  egg 
collections,  to  end  by  becoming  most  zealous  protectors  of  the  birds. 
The  humane  qualities  within  these  boys  budded  and  blossomed  in  the 
growing  knowledge  of  the  lives  of  the  birds.  At  Cornell  University,  it  is 
a well  known  fact  that  those  students  who  turn  aside  so  as  not  to  crush 
the  ant,  caterpillar  or  cricket  on  the  pavement  are  almost  invariably 
those  that  are  studying  entomology;  and  in  America  it  is  the  botanists 
themselves  who  are  leading  the  crusade  for  flower  protection. 

Thus,  the  nature-study  teacher,  if  she  does  her  work  well,  is  a sure  aid 
in  inculcating  a respect  for  the  rights  of  all  living  beings  to  their  own  lives ; 
and  she  needs  only  to  lend  her  influence  gently  in  this  direction  to  change 
carelessness  to  thoughtfulness  and  cruelty  to  kindness.  But  with  this 
impetus  toward  a reverence  for  life,  the  teacher  soon  finds  herself  in  a 
dilemma  from  which  there  is  no  logical  way  out,  so  long  as  she  lives  in  a 
world  where  lamb  chop,  beefsteak  and  roast  chicken  are  articles  of  ordi-

nary  diet;  a world  in  fact,  where  every  meal  is  based  upon  the  death  of 
some  creature.  For  if  she  places  much  emphasis  upon  the  sacredness  of 
life,  the  children  soon  begin  to  question  whether  it  be  right  to  slay  the 
lamb  or  the  chicken  for  their  own  food.  It  would  seem  that  there  is 
nothing  for  the  consistent  nature-study  teacher  to  do  but  become  a 
vegetarian,  and  even  then  there  might  arise  refinements  in  this  question 
of  taking  life,  she  might  have  to  consider  the  cruelty  to  asparagus  in 
cutting  it  off  in  plump  infancy,  or  the  ethics  of  devouring  in  the  turnip  the 
food  laid  up  by  the  mother  plant  to  perfect  her  seed.  In  fact,  a most 
rigorous  diet  would  be  forced  upon  the  teacher  who  should  refuse  to  sus- 
tain her  own  existence  at  the  cost  of  life;  and  if  she  should  attempt  to 
teach  the  righteousness  of  such  a diet  she  would  undoubtedly  forfeit  her 
position;  and  yet  what  is  she  to  do!  She  will  soon  find  herself  in  the 
position  of  a certain  lady  who  placed  sheets  of  sticky  fly-paper  around  her 
kitchen  to  rid  her  house  of  flies,  and  then  in  mental  anguish  picked  off  the 
buzzing,  struggling  victims  and  sought  to  clean  their  too  adhesive  wings 
and  legs. 

In  fact,  drawing  the  line  between  what  to  kill  and  what  to  let  live, 
requires  the  use  of  common  sense  rather  than  logic.  First  of  all,  the 
nature-study  teacher,  while  exemplifying  and  encouraging  the  humane 
attitude  toward  the  lower  creatures,  and  repressing  cruelty  which 
wantonly  causes  suffering,  should  never  magnify  the  terrors  of  death. 
Death  is  as  natural  as  life  and  the  inevitable  end  of  physical  life  on  our 
globe.  Therefore,  every  story  and  every  sentiment  expressed  which 
makes  the  child  feel  that  death  is  terrible,  is  wholly  wrong.  The  one  right 
way  to  teach  about  death  is  not  to  emphasize  it  one  way  or  another,  but  to 
deal  with  it  as  a circumstance  common  to  all;  it  should  be  no  more 
emphasized  than  the  fact  that  creatures  eat  or  fall  asleep. 

Another  thing  for  the  nature-study  teacher  to  do  is  to  direct  the 
interest  of  the  child  so  that  it  shall  center  upon  the  hungry  creature 
rather  than  upon  the  one  which  is  made  into  the  meal.  It  is  well  to 
emphasize  the  fact  that  one  of  the  conditions  imposed  upon  every  living 
being  in  the  woods  and  fields,  is  that  it  is  entitled  to  a meal  when  it  is 
hungry,  if  it  is  clever  enough  to  get  it.  The  child  naturally  takes  this 
view  of  it.  I remember  well  as  a child  I never  thought  particularly  about 
the  mouse  which  my  cat  was  eating;  in  fact,  the  process  of  transmuting 
mouse  into  cat  seemed  altogether  proper,  but  when  the  cat  played  with 
the  mouse,  that  was  quite  another  thing,  and  was  never  permitted. 
Although  no  one  appreciates  more  deeply  than  I the  debt  which  we  owe  to 
Thompson-Seton  and  writers  of  his  kind,  who  have  placed  before  the 
public  the  animal  story  from  the  animal  point  of  view  and  thus  set  us  all 
to  thinking,  yet  it  is  certainly  wrong  .to  impress  this  view  too  strongly 
upon  the  young  and  sensitive  child.  In  fact,  this  process  should  not 
begin  until  the  judgment  and  the  understanding  is  well  developed,  for  we 
all  know  that  although  seeing  the  other  fellow’s  standpoint  is  a source  of 
strength  and  breadth  of  mind,  yet  living  the  other  fellow’s  life  is,  at 
best,  an  enfeebling  process  and  a futile  waste  of  energy. 


The  Teaching  of  N ature-Study 


13 


SHOULD  THE  NATURE-STUDY  TEACHER  TEACH  HOW  TO  DESTROY  LIFE  ? 

FT  IS  probably  within  the  proper  scope  of  the  nature-study 
— x teacher  to  place  emphasis  upon  the  domain  of  man,  who 
being  the  most  powerful  of  all  animals,  asserts  his  will  as 
to  which  ones  shall  live  in  his  midst.  From  a standpoint 
of  abstract  justice,  the  stray  cat  has  just  as  much  right 
to  kill  and  eat  the  robin  which  builds  in  the  vine  of  my 
porch  as  the  robin  has  to  pull  and  eat  the  earthworms 
from  my  lawn;  but  the  place  is  mine,  and  I choose  to  kill 
the  cat  and  preserve  the  robin. 

When  emphasizing  the  domain  of  man,  we  may  have  to  deal  with  the 
killing  of  creatures  which  are  injurious  to  his  interests.  Nature-study 
may  be  tributary  to  this,  in  a measure,  and  indirectly,  but  it  is  surely  not 
nature-study.  For  example,  the  child  studies  the  cabbage  butterfly  in 
all  its  stages,  the  exquisitely  sculptured  yellow  egg,  the  velvety  green 
caterpillar,  the  chrysalis  with  its  protecting  colors,  the  white- winged 
butterfly,  and  becomes  interested  in  the  life  of  the  insect.  Not  under  any 
consideration,  when  the  attention  of  the  child  is  focused  on  the  insect, 
should  we  suggest  a remedy  for  it  when  a pest.  Let  the  life-story  of  the 
butterfly  stand  as  a fascinating  page  of  nature’s  book.  But  later,  when 
the  child  enters  on  his  career  as  a gardener,  when  he  sets  out  his  row  of 
cabbage  plants  and  waters  and  cultivates  them,  and  does  his  best  to  bring 
them  to  maturity,  along  comes  the  butterfly,  now  an  arch  enemy,  and 
begins  to  rear  her  progeny  on  the  product  of  his  toil.  Now  the  child’s 
interest  is  focused  on  the  cabbage,  and  the  question  is  not  one  of  killing 
insects  so  much  as  of  saving  plants.  In  fact,  there  is  nothing  in  spraying 
the  plants  with  Paris  green  which  suggests  cruelty  to  innocent  caterpillars, 
nor  is  the  process  likely  to  harden  the  child’s  sensibilities. 

To  gain  knowledge  of  the  life-story  of  insects  or  other  creatures  is 
nature-study.  To  destroy  them  as  pests  is  a part  of  Agriculture  or 
Horticulture.  The  one  may  be  of  fundamental  assistance  to  the  other, 
but  the  two  are  quite  separate  and  should  never  be  confused. 

THE  FIELD  NOTE-BOOK 

A field  note-book  may  be  made  a joy  to  the  pupil  and  a help  to  the 
teacher.  Any  kind  of  a blank  book  will  do  for  this,  except  that  it  should 
not  be  too  large  to  be  carried  in  the  pocket,  and  it  should  always  have  the 
pencil  attached.  To  make  the  note-book  a success  the  following  rules 
should  be  observed : 

(a)  The  book  should  be  considered  the  personal  property  of  the  child 
and  should  never  be  criticized  by  the  teacher  except  as  a matter  of 
encouragement;  for  the  spirit  in  which  the  notes  are  made,  is  more  im- 
portant than  the  information  they  cover. 

(b)  The  making  of  drawings  should  be  encouraged  for  illustrating 
what  is  observed.  A graphic  drawing  is  far  better  than  a long  description 
of  a natural  object. 

(c)  The  note-book  should  not  be  regarded  as  a part  of  the  work  in 
English.  The  spelling,  language  and  writing  of  the  notes  should  all  be 
exempt  from  criticism. 

(d)  As  occasion  offers,  outlines  for  observing  certain  plants  or  ani- 
mals may  be  placed  in  the  note-book  previous  to  the  field  excursion  so  as 
to  give  definite  points  for  the  work. 


14 


Handbook  of  Nature-Study 


(e)  No  child  should  be  compelled  to  have  a note-book. 

The  field  note-book  is  a veritable  gold  mine  for  the  nature-study 
teacher  to  work,  in  securing  voluntary  and  happy  observations  from  the 
pupils  concerning  their  out-of-door  interests.  It  is  a friendly  gate  which 
admits  the  teacher  to  a knowledge  of  what  the  child  sees  and  cares  for. 
Through  it  she  may  discover  where  the  child’s  attention  impinges  upon 
the  realm  of  nature  and  thus  may  know  where  to  find  the  starting  point  for 
cultivating  larger  intelligence  and  a wider  interest.

the  hooks  of  Thompson-Seton. 


The  Teaching  of  Nature-Study 


i5 


I have  examined  many  field  note-books  kept  by  pupils  in  the  inter- 
mediate grades  and  have  been  surprised  at  their  plenitude  of  accurate 
observation  and  graphic  illustration.  These  books  ranged  from  blank 
account  books  furnished  by  the  family  grocer  up  to  a quarto,  the  pages  of 
which  were  adorned  with  many  marginal  illustrations  made  in  passionate 
admiration  of  Thompson-Seton’s  books  and  filled  with  carefully  trans- 
cribed text,  that  showed  the  direct  influence  of  Thoreau.  These  books,  of 
whatever  quality,  are  precious  beyond  price  to  their  owners.  And  why 
not?  For  they  represent  what  cannot  be  bought  or  sold,  personal 
experience  in  the  happy  world  of  out-of-doors. 

THE  FIELD  EXCURSION 

NY  teachers  look  upon  the  field  excursion  as  a precar- 
ious voyage,  steered  between  the  Scylla  of  hilarious 
seeing  too  much  and  the  Charybdis  of  seeing  nothing  at 
all  because  of  the  zest  which  comes  from  freedom  in  the 
fields  and  wood.  This  danger  can  be  obviated  if  the 
teacher  plans  the  work  definitely  before  starting,  and 
demands  certain  results. 

It  is  a mistake  to  think  that  a half  day  is  necessary  for  a field  lesson, 
since  a very  efficient  field  trip  may  be  made  during  the  ten  or  fifteen 
minutes  at  recess,  if  it  is  well  planned.  Certain  questions  and  lines  of 
investigation  should  be  given  the  pupils  before  starting  and  given  in  such 
a manner  as  to  make  them  thoroughly  interested  in  discovering  the  facts,. 
A certain  teacher  in  New  York  State  has  studied  all  the  common  plants 
and  trees  in  the  vicinity  of  her  school  with  these  recess  excursions  and  the 
pupils  have  been  enthusiastic  about  the  work. 

The  half  hour  excursion  should  be  preceded  by  a talk  concerning  the 
purposes  of  the  outing  and  the  pupils  must  know  that  certain  observa- 
tions are  to  be  made  or  they  will  not  be  permitted  to  go  again.  This 
should  not  be  emphasized  as  a punishment;  but  they  should  be  made  to 
understand  that  a field  excursion  is  only,  naturally  enough,  for  those  who 
wish  to  see  and  understand  outdoor  life.  For  all  field  work,  the  teacher 
should  make  use  of  the  field  notebook  which  should  be  a part  of  the  pupils’ 
equipment. 

PETS  AS  NATURE-STUDY  SUBJECTS 

~ ^ asY'  JITTLE  attention  has  been  given  to  making  the  child  un- 

derstand what  would  be  the  lives  of  his  pets  if  they  were 
in  their  native  environment;  or  to  relating  their  habits 
and  lives  as  wild  animals.  Almost  any  pet,  if  properly 
observed,  affords  an  admirable  opportunity  for  under- 
standing the  reasons  why  its  structure  and  peculiar  habits 
may  have  made  it  successful  among  other  creatures  and  in  other  lands. 

Moreover  the  actions  and  the  daily  life  of  the  pet  make  interesting 
subject  matter  for  a note-book.  The  lessons  on  the  dog,  rabbit  and  horse 
as  given  in  this  volume  may  suggest  methods  for  such  study,  and  with 
apologies  that  it  is  not  better  and  more  interesting,  I have  placed  with  the 
story  of  the  squirrel  a few  pages  from  one  of  my  own  note-books  regarding 
my  experiences  with  “Furry.”  I include  this  record  as  a suggestion  for 
the  children  that  they  should  keep  note-books  of  their  pets.  It  will  lead 


1 6 Handbook  of  Nature-Study 

them  to  closer  observation  and  to  a better  and  more  natural  expression 
of  their  experiences. 

THE  CORRELATION  OF  NATURE-STUDY  WITH  LANGUAGE  WORK 

ATURE-STUDY  should  be  so  much  a part  of  the  child’s 
thought  and  interest  that  it  will  naturally  form  a thought 
core  for  other  subjects  quite  unconsciously  on  his  part. 
In  fact,  there  is  one  safe  rule  for  correlation  in  this  case,  it 
is  legitimate  and  excellent  training  as  long  as  the  pupil 
does  not  discover  that  he  is  correlating.  But  there  is 
something  in  human  nature  which  revolts  against  doing  one  thing  to 
accomplish  quite  another.  A boy  once  said  to  me,  “I’d  rather  never  go 
on  a field  excursion  than  to  have  to  write  it  up  for  English,”  a sentiment 
I sympathized  with  keenly ; ulterior  motive  is  sickening  to  the  honest 
spirit.  But  if  that  same  boy  had  been  a member  of  a field  class  and  had 
enjoyed  all  the  new  experiences  and  had  witnessed  the  interesting  things 
discovered  on  this  excursion,  and  if  later  his  teacher  had  asked  him  to 
write  for  her  an  account  of  some  part  of  it,  because  she  wished  to  know 
what  he  had  discovered , the  chances  are  that  he  would  have  written  his 
story  joyfully  and  with  a certain  pride  that  would  have  counted  much  for 
achievement  in  word  expression. 

When  Mr.  John  Spencer,  known  to  so  many  children  in  New  York 
State  as  “Uncle  John,”  was  conducting  the  Junior  Naturalist  Clubs,  the 
teachers  allowed  letters  to  him  to  count  for  language  exercises;  and  the 
eagerness  with  which  these  letters  were  written  should  have  given  the 
teachers  the  key  to  the  proper  method  of  teaching  English.  Mr.  Spencer 
requested  the  teachers  not  to  correct  the  letters,  because  he  wished  the 
children  to  be  thinking  about  the  subject  matter  rather  than  the  form  of 
expression.  But  so  anxious  were  many  of  the  pupils  to  make  their  letters 
perfect,  that  they  earnestly  requested  their  teachers  to  help  them  write 
correctly,  which  was  an  ideal  condition  for  teaching  them  English. 
Writing  letters  to  Uncle  John  was  such  a joy  to  the  pupils  that  it  was  used 
as  a privilege  and  a reward  of  merit  in  many  schools.  One  rural  teacher 
reduced  the  percentage  of  tardiness  to  a minimum  by  giving  the  first 
period  in  the  morning  to  the  work  in  English  which  consisted  of  letters  to 
Uncle  John. 

WTiy  do  pupils  dislike  writing  English  exercises  ? Simply  because  they 
are  not  interested  in  the  subject  they  are  asked  to  write  about,  and  they 
know  that  the  teacher  is  not  interested  in  the  information  contained  in  the 
essay.  But  when  they  are  interested  in  the  subject  and  write  about  it  to 
a person  who  is  interested,  the  conditions  are  entirely  changed.  If  the 
teacher,  overwhelmed  as  she  is  by  work  and  perplexities,  could  only  keep 
in  mind  that  the  purpose  of  a language  is,  after  all,  merely  to  convey  ideas, 
some  of  her  perplexities  would  fade  away.  A conveyance  naturally 
should  be  fitted  for  the  load  it  is  to  carry,  and  if  the  pupil  acquires  the 
load  first  he  is  very  likely  to  construct  a conveyance  that  will  be  adequate. 
How  often  the  conveyance  is  made  perfect  through  much  effort  and 
polished  through  agony  of  spirit  and  the  load  entirely  forgotten ! 

Nature-study  lessons  give  much  excellent  subject  matter  for  stories 
and  essays,  but  these  essays  should  never  be  criticized  or  defaced  with  the 
blue  pencil.  They  should  be  read  with  interest  by  the  teacher;  the  mis-

takes  made  in  them,  so  transformed  as  to  be  unrecognizable,  may  be  used 
for  drill  exercises  in  grammatical  construction.  After  all,  grammar  and 
spelling  are  only  gained  by  practice  and  there  is  no  royal  road  leading  to 
their  acquirement. 

THE  CORRELATION  OF  NATURE-STUDY  AND  DRAWING 

HE  correlation  of  nature-study  and  drawing  is  so  natural 
and  inevitable  that  it  needs  never  be  revealed  to  the 
pupil.  When  the  child  is  interested  in  studying  a.ny  ob- 
ject, he  enjoys  illustrating  his  observations  with  draw- 
ings ; the  happy  absorption  of  children  thus  engaged  is  a 
delight  to  witness.  At  its  best,  drawing  is  a perfectly 
natural  method  of  self-expression.  The  savage  and  the  young  child, 
both  untutored,  seek  to  express  themselves  and  their  experiences  by 
this  means.  It  is  only  when  the  object  to  be  drawn  is  foreign  to  the  in- 
terest of  the  child  that  drawing  is  a task. 

Nature-study  offers  the  best  means  for  bridging  the  gap  that  lies 
between  the  kindergarten  child  who  makes  drawings  because  he  loves  to 
and  is  impelled  to  from  within,  and  the  pupil  in  the  grades  who  is  obliged 
to  draw  what  the  teacher  places  before  him.  From  making  crude  and 
often  meaningless  pencil  strokes,  which  is  the  entertainment  of  the  young 
child,  the  outlining  of  a leaf  or  some  other  simple  and  interesting  natural 
object,  is  a normal  step  full  of  interest  for  the  child  because  it  is  still  self- 
expression. 

Miss  Mary  E.  Hill  gives  every  year  in  the  Goodyear  School  of  Syracuse 
an  exhibition  of  the  drawings  made  by  the  children  in  the  nature-study 
classes;  and  these  are  universally  so  excellent  that  most  people  regard 
them  as  an  exhibition  from  the  Art  Department;  and  yet  many  of  these 
pupils  have  never  had  lessons  in  drawing.  They  have  learned  to  draw 
because  they  like  to  make  pictures  of  the  living  objects  which  they  have 
studied.  One  year  there  were  many  pictures  of  toads  in  various  stages  in 
this  exhibit,  and  although  their  anatomy  was  sometimes  awry  in  the  pic- 
tures, yet  there  was  a certain  vivid  expression  of  life  in  their  representa- 
tion; one  felt  that  the  toads  could  jump.  Miss  Hill  allows  the  pupils  to 
choose  their  own  medium,  pencil,  crayon,  or  water-color,  and  says  that 
they  seem  to  feel  which  is  best.  For  instance,  when  drawing  the  outline 
of  trees  in  winter  they  choose  pencil,  but  when  representing  the  trillium 
or  iris  they  prefer  the  water-color,  while  for  bitter-sweet  and  crocuses  they 
choose  the  colored  crayons. 

It  is  through  this  method  of  drawing  that  which  interests  him,  that  the 
child  retains  and  keeps  as  his  own,  what  should  be  an  inalienable  right,  a 
graphic  method  of  expressing  his  own  impressions.  Too  much  have  we 
emphasized  drawing  as  an  art ; it  may  be  an  art,  if  the  one  who  draws  is 
an  artist ; but  if  he  is  not  an  artist  he  still  has  a right  to  draw  if  it  pleases 
him  to  do  so.  We  might  as  well  declare  that  a child  should  not  speak 
unless  he  put  his  words  into  poetry,  as  to  declare  that  he  should  not  draw 
because  his  drawings  are  not  artistic.

Handbook  of  Nature-Study 


THE  CORRELATION  OF  NATURE-STUDY  WITH  GEOGRAPHY 

IFE  depends  upon  its  environment.  Geographical 
conditions  and  limitations  have  shaped  the  mold 
into  which  plastic  life  has  been  poured  and  by 
which  its  form  has  been  modified.  It  may  be 
easy  for  the  untrained  mind  to  see  how  the  des- 
erts and  oceans  affect  life.  Cattle  may  not  roam 
in  the  former  because  there  is  nothing  there  for 
them  to  eat,  nor  may  they  occupy  the  latter  be- 
cause they  are  not  fitted  for  breathing  air  in  the 
water.  And  yet  the  camel  can  endure  thirst  and 
live  on  the  scant  food  of  the  desert;  and  the 
whale  is  a mammal  fitted  to  live  in  the  sea.  The  question  is,  how  are  we 
to  impress  the  child  with  the  “ have  to  ” which  lies  behind  all  these  geo- 
graphical facts.  If  animals  live  in  the  desert  they  have  to  subsist  on 
scant  and  peculiar  food  which  grows  there;  they  have  to  get  along  with 
little  water;  they  have  to  endure  heat  and  sand  storms;  they  have  to 
have  eyes  that  will  not  become  blinded  by  the  vivid  reflection  of  the  sun- 
light on  the  sand ; they  have  to  be  of  sand  color  so  that  they  may  escape 
the  eyes  of  their  enemies  or  creep  upon  their  prey  unperceived. 

All  these  have  to’s  are  not  mere  chance,  but  they  have  existed  so  long 
that  the  animal,  by  constantly  coming  in  contact  with  them,  has  attained 
its  present  form,  and  habits. 

There  are  just  as  many  have  to’s  in  the  stream  or  the  pond  back  of  the 
school-house,  on  the  dry  hillside  behind  it  or  in  the  woods  beyond  the  creek 
as  there  are  in  desert  or  ocean ; and  when  the  child  gets  an  inkling  of  this 
fact,  he  has  made  a great  step  into  the  realm  of  geography.  When  he 
realizes  why  water  lilies  can  grow  only  in  still  water  that  is  not  too  deep 
and  which  has  a silt  bottom,  and  why  the  cat-tails  grow  in  swamps  where 
there  is  not  too  much  water,  and  why  the  mullen  grows  in  the  dry  pasture, 
and  why  the  hepatica  thrives  in  the  rich,  damp  woods,  and  why  the  daisies 
grow  in  the  meadows,  he  will  understand  that  this  partnership  of  nature 
and  geography  illustrates  the  laws  which  govern  life.  Many  phases  of 
physical  geography  belong  to  the  realm  of  nature-study;  the  brook,  its 
course,  its  work  or  erosion  and  sedimentation ; the  rocks  of  many  kinds, 
the  soil,  the  climate,  the  weather,  are  all  legitimate  subjects  for  nature- 
study  lessons. 

THE  CORRELATION  OF  NATURE-STUDY  WITH  HISTORY 

ERE  are  many  points  where  nature-study  impinges 
upon  history  in  a way  that  may  prove  the  basis  for  an 
inspiring  lesson.  Many  of  our  weeds,  cultivated  plants 
and  domestic  animals  have  been  introduced  from  Eu- 
rope and  are  a part  of  our  colonial  history;  while  there 
are  many  of  the  most  commonly  seen  creatures  which 
have  played  their  part  in  the  history  of  ancient  times. 
For  instance,  the  bees  which  gave  to  man  the  only 
means  available  to  him  for  sweetening  his  food  until  the  1 7th  century, 
were  closely  allied  to  the  home  life  of  ancient  peoples.  The  buffalo 
which  ranged  our  western  plains  had  much  to  do  with  the  life  of  the  red 
man.  The  study  of  the  grasshopper  brings  to  the  child’s  attention  stories 


The  Teaching  of  N atur e -Study

of  the  locusts’  invasion  mentioned  in  the  Bible,  and  the  stars  which 
witnessed  our  creation  and  of  which  Job  sang  and  the  ancients  wrote, 
shine  over  our  heads  every  night. 

But  the  trees,  through,  the  lengthy  span  of  their  lives,  cover  more  history 
individually,  than  do  other  organisms.  In  glancing  across  the  wood-covered 
hills  of  New  York  one  often  sees  there,  far  above  the  other  trees,  the 
gaunt  crowns  of  old  white  pines.  Such  trees  belonged  to  the  forest 
primeval  and  may  have  attained  the  age  of  two  centuries;  they  stand 
there  looking  out  over  the  world,  relics  of  another  age  when  America  be- 
longed to  the  red  man,  and  the  bear  and  the  panther  played  or  fought 
beneath  them.  The  cedars  live  longer  than  do  the  pines  and  the  great 
scarlet  oak  may  have  attained  the  age  of  four  centuries  before  it  yields 
to  fate. 

Perhaps  in  no  other  way  may  the  attention  of  the  pupil  be  turned  so 
naturally  to  past  events,  as  through  the  thought  that  the  life  of  such  a tree 
has  spanned  so  much  of  human  history.  The  life  history  of  one  of  these 
ancient  trees  should  be  made  the  center  of  local  history;  let  the  pupils 
find  when  the  town  was  first  settled  by  the  whites  and  where  they  came 
from  and  how  large  the  tree  was  then.  What  Indian  tribes  roamed  the 
woods  before  that  and  what  animals  were  common  in  the  forest  when  this 
tree  was  a sapling?  Thus  may  be  brought  out  the  chief  events  in  the 
history  of  the  county  and  township,  when  they  were  established  and  for 
whom  or  what  they  were  named ; and  a comparison  of  the  present 
industries  may  be  made  with  those  of  a hundred  years  ago. 


THE  CORRELATION  OF  NATURE-STUDY  WITH  ARITHMETIC 

HE  arithmetical  problems  presented  by  nature-study 
are  many;  some  of  them  are  simple  and  some  of 
them  are  complicated,  and  all  of  them  are  illumin- 
ing. Seed  distribution  especially  lends  itself  to 
computation;  a milkweed  pod  contains  140  seeds; 
there  are  five  such  pods  on  one  plant,  each  milkweed 
plant  requires  at  least  one  square  foot  of  ground  to 
grow  on ; how  much  ground  would  be  required  to 
grow  all  of  the  seeds  from  this  one  plant  ? Or,  count 
the  seeds  in  one  dandelion  head,  multiply  by  the 
number  of  flower  heads  on  the  plant  and  estimate 
how  many  plants  can  grow  on  a square  foot,  then 
ask  a boy  how  long  it  would  take  for  one  dandelion 
plant  to  cover  his  father’s  farm  with  its  progeny;  or 
count  the  blossoms  on  one  branch  of  an  apple  tree, 
later  count  the  ripened  fruit ; what  percentage  of  blossoms  matured  in- 
to fruit  ? Measuring  trees,  their  height  and  thickness  and  computing  the 
lumber  they  will  make  combines  arithmetic  and  geometry,  and  so  on  ad 
infinitum. 

As  a matter  of  fact,  the  teacher  will  find  in  almost  every  nature  lesson 
an  arithmetic  lesson ; and  when  arithmetic  is  used  in  this  work,  it  should 
be  vital  and  inherent  and  not  “tacked  on;”  the  pupils  should  be  really 
interested  in  the  answers  to  their  problems;  and  as  with  all  correlation, 
the  success  of  it  depends  upon  the  genius  of  the  teacher.

GARDENING  AND  NATURE-STUDY 

ERRONEOUSLY,  some  people  maintain  that  gardening  is 
nature-study;  this  is  not  .so  necessarily  nor  ordinarily. 
^ Gardening  may  be  a basis  for  nature-study  but  it  is 
* rarely  made  so  to  any  great  extent.  Even  the  work  in 
children’s  gardens  is  so  conducted  that  the  pupils  know 
little  or  nothing  of  the  flowers  or  vegetables  which  they 
grow  except  their  names,  their  uses  to  man  and  how  to 
cultivate  them.  They  are  taught  how  to  prepare  the  soil,  but  the 
reason  for  this  from  the  plant’s  standpoint  is  never  revealed;  and  if 
the  child  becomes  acquainted  with  the  plants  in  his  garden,  he  makes  the 
discovery  by  himself.  All  this  is  nothing  against  gardening!  It  is  a 
wholesome  and  valuable  experience  for  a child  to  learn  how  to  make  a 
garden  even  if  he  remains  ignorant  of  the  interesting  facts  concerning  the 
plants  which  he  there  cultivates.  But  if  the  teachers  are  so  inclined,  they 
mayl  find  in  the  garden  and  its  products,  the  most  interesting  material  for 
the  best  of  nature  lessons.  Every  plant  the  child  grows  is  an  individual 
with  its  own  peculiarities  as  well  as  those  of  its  species  in  manner  of 
growth.  Its  roots,  stems  and  leaves  are  of  certain  form  and  structure; 
and  often  the  special  uses  to  the  plant  of  its  own  kind  of  leaves,  stems  and 
roots  are  obvious.  Each  plant  has  its  own  form  of  flower  and  even  its 
own  tricks  for  securing  pollination ; and  its  own  manner  of  developing 
and  scattering  its  seeds.  Every  weed  of  the  garden  has  developed 
some  special  method  of  winning  and  holding  its  place  among  the  culti- 
vated plants ; and  in  no  other  way  may  the  child  so  fully  and  naturally 
come  into  a comprehension  of  that  term  “the  survival  of  the  fittest  ” 
as  by  studying  the  ways  of  the  fit  as  exemplified  in  the  triumphant  weeds 
of  his  garden. 

Every  earthworm  working  below  the  soil  is  doing  something  for  the 
garden.  Every  bee  that  visits  the  flowers  there  is  on  an  errand  for  the 
garden  as  well  as  for  herself.  Every  insect  feeding  on  leaf  or  root  is  doing 
something  to  the  garden.  Every  bird  that  nests  near  by  or  that  ever 
visits  it,  is  doing  something  which  affects  the  life  and  the  growth  of  the 
garden.  What  all  of  these  uninvited  guests  are  doing  is  one  field  of 
garden  nature-study.  Aside  from  all  this  study  of  individual  life  in  the 
garden  which  even  the  youngest  child  may  take  part  in,  there  are  the 
more  advanced  lessons  on  the  soil.  What  kind  of  soil  is  it  ? From  what 
sort  of  rock  was  it  formed  ? What  renders  it  mellow  and  fit  for  the  grow- 
ing of  plants  ? Moreover,  what  do  the  plants  get  from  it  ? How  do  they 
get  it?  What  do  they  do  with  what  they  get? 

This  leads  to  the  subject  of  plant  physiology,  the  elements  of  which 
may  be  taught  simply  by  experiments  carried  on  by  the  children  them- 
selves, experiments  which  should  demonstrate  the  sap  currents  in  the 
plant ; the  use  of  water  to  carry  food  and  in  making  the  plant  rigid ; the 
use  of  sunshine  in  making  the  plant  food  in  the  leaf  laboratories;  the 
nourishment  provided  for  the  seed  and  its  germination,  and  many  other 
similar  lessons. 

A child  who  makes  a garden,  and  thus  becomes  intimate  with  the  plants 
he  cultivates,  and  comes  to  understand  the  interrelation  of  the  various 
forms  of  life  which  he  finds  in  his  garden,  has  progressed  far  in  the  funda- 
mental knowledge  of  nature’s  ways  as  well  as  in  a practical  knowledge 
of  agriculture.

NATURE-STUDY  AND  AGRICULTURE 


IUCKILY,  thumb-rule  agriculture  is  being  pushed  to  the  wall 
in  these  enlightened  days.  Thumb  rules  would  work  much 
better  if  nature  did  not  vary  her  performances  in  such  a 
confusing  way.  Government  experiment  stations 
were  established  because  thumb  rules  for  farming 
were  unreliable  and  disappointing;  and  all  the  work 
of  all  the  experiment  stations  has  been  simply  ad- 
vanced nature-study  and  its  application  to  the  prac- 
tice of  agriculture.  Both  nature-study  and  agriculture  are  based  upon 
the  study  of  life  and  the  physical  conditions  which  encourage  or  limit  life; 
this  is  known  to  the  world  as  the  study  of  the  natural  sciences ; and  if  we 
see  clearly  the  relation  of  nature-study  to  science,  we  may  understand 
better  the  relation  of  nature-study  to  agriculture,  which  is  based  upon 
the  sciences. 


Nature-study  is  science  brought  home.  It  is  a knowledge  of  botany, 
zoology  and  geology  as  illustrated  in  the  dooryard,  the  corn-field  or  the 
woods  back  of  the  house.  Some  people  have  an  idea  that  to  know  these 
sciences  one  must  go  to  college;  they  do  not  understand  that  nature  has 
furnished  the  material  and  laboratories  on  every  farm  in  the  land.  Thus, 
by  beginning  with  the  child  in  nature-study  we  take  him  to  the  laboratory 
of  the  wood  or  garden,  the  roadside  or  the  field,  and  his  materials  are  the 
wild  flowers  or  the  weeds,  or  the  insects  that  visit  the  golden-rod  or  the 
bird  that  sings  in  the  maple  tree,  or  the  woodchuck  whistling  in  the  pas- 
ture. The  child  begins  to  study  living  things  anywhere  or  everywhere, 
and  his  progress  is  always  along  the  various  tracks  laid  down  by  the  laws 
of  life,  along  which  his  work  as  an  agriculturist  must  always  progress  if  it 
is  to  be  successful. 

The  child  through  nature-study  learns  the  way  a plant  grows,  whether 
it  be  an  oak,  a turnip  or  a pigweed;  he  learns  how  the  roots  of  each  is 
adapted  to  its  needs ; how  the  leaves  place  themselves  to  get  the  sunshine 
and  why  they  need  it ; and  how  the  flowers  get  their  pollen  carried  by  the 
bee  or  wind;  and  how  the  seeds  are  finally  scattered  and  planted.  Or  he 
learns  about  the  life  of  the  bird,  whether  it  be  a chicken,  an  owl  or  a 
bobolink ; he  knows  how  each  bird  gets  its  food  and  what  its  food  is,  where 
it  lives,  where  it  nests  and  its  relation  to  other  living  things.  He  studies 
the  bumblebee  and  discovers  its  great  mission  of  pollen  carrying  for  many 
flowers,  and  in  the  end  would  no  sooner  strike  it  dead  than  he  would 
voluntarily  destroy  his  clover  patch.  This  is  the  kind  of  learning  we  call 
nature-study  and  not  science  or  agriculture.  But  the  country  child  can 
never  learn  anything  in  nature-study  that  has  not  something  to  do  with 
science;  and  that  has  not  its  own  practical  lesson  for  him,  when  he  shall 
become  a farmer. 

Some  have  argued,  “Why  not  make  nature-study  along  the  lines  of 
agriculture  solely?  Why  should  not  the  child  begin  nature-study  with 
the  cabbage  rather  than  the  wild  flowers?”  This  argument  carried  out 
logically  provides  recreation  for  a boy  in  hoeing  com  rather  than  in  play- 
ing ball.  Many  parents  in  the  past  have  argued  thus  and  have,  in  conse- 
quence, driven  thousands  of  splendid  boys  from  the  country  to  the  city 
with  a loathing  in  their  souls  for  the  drudgery  which  seemed  all  there  was 
to  farm  life.  The  reason  why  the  wild  flowers  may  be  selected  for  begin- 


22 


Handbook  of  Nature-Study 


ning  the  nature-study  of  plants,  is  because  every  child  loves  these  wood- 
land posies,  and  his  happiest  hours  are  spent  in  gathering  them.  Never 
yet  have  we  known  of  a case  where  a child  having  gained  his  knowledge  of 
the  way  a plant  lives  through  studying  the  plants  he  loves,  has  failed  to  be 
interested  and  delighted  to  find  that  the  wonderful  things  he  discovered 
about  his  wild  flower  may  be  true  of  the  vegetable  in  the  garden,  or  the 
purslane  which  fights  with  it  for  ground  to  stand  upon. 

Some  have  said,  “We,  as  farmers,  care  only  to  know  what  concerns  our 
pocket-books;  we  wish  only  to  study  those  things  which  we  must,  as 
farmers,  cultivate  or  destroy.  We  do  not  care  for  the  butterfly,  but  we 
wish  to  know  the  plum  weevil ; we  do  not  care  for  the  trillium  but  we  are 
interested  in  the  onion;  we  do  not  care  for  the  meadow-lark  but  we 
cherish  the  gosling.”  This  is  an  absurd  argument  since  it  is  a mental 
impossibility  for  any  human  being  to  discriminate  between  two  things 
when  he  knows  or  sees  only  one.  In  order  to  understand  the  important 
economic  relations  to  the  world  of  one  plant  or  animal,  it  is  absolutely 
necessary  to  have  a wide  knowledge  of  other  plants  and  animals.  One 
might  as  well  say,  “I  will  see  the  approaching  cyclone,  but  never  look  at 
the  sky;  I will  look  at  the  clover  but  not  see  the  dandelion ; I will  look  for 
the  sheriff  when  he  comes  over  the  hill  but  will  not  see  any  other  team  on 
the  road.” 

Nature-study  is  an  effort  to  make  the  individual  use  his  senses  instead 
of  losing  them ; to  train  him  to  keep  his  eyes  open  to  all  things  so  that  his 
powers  of  discrimination  shall  be  based  on  wisdom.  The  ideal  farmer  is 
not  the  man  who  by  hazard  and  chance  succeeds ; he  is  the  man  who  loves 
his  farm  and  all  that  surrounds  it  because  he  is  awake  to  the  beauty  as  well 
as  to  the  wonders  which  are  there ; he  is  the  man  who  understands  as  far 
as  may  be  the  great  forces  of  nature  which  are  at  work  around  him,  and 
therefore,  he  is  able  to  make  them  work  for  him.  For  what  is  agriculture 
save  a diversion  of  natural  forces  for  the  benefit  of  man ! The  farmer  who 
knows  these  forces  only  when  restricted  to  his  paltry  crops,  and  has  no 
idea  of  their  larger  application,  is  no  more  efficient  as  a farmer  than  would 
a man  be  as  an  engineer  who  knew  nothing  of  his  engine  except  how  to 
start  and  stop  it. 

In  order  to  appreciate  truly  his  farm,  the  farmer  must  needs  begin  as  a 
child  with  nature-study ; in  order  to  be  successful  and  make  the  farm  pay, 
he  must  needs  continue  in  nature-study;  and  to  make  his  declining  years 
happy,  content,  full  of  wide  sympathies  and  profitable  thought,  he  must 
needs  conclude  with  nature-study;  for  nature-study  is  the  alphabet  of 
agriculture  and  no  word  in  that  great  vocation  may  be  spelled  without  it. 


NATURE-STUDY  CLUBS 


\HE  organizing  of  a club  by  the  pupils  for  the  purpose  of 
studying  out-of-door  life,  is  a great  help  and  inspiration 
to  the  work  in  nature-study  in  the  classroom.  The 
essays  and  the  talks  before  the  club,  prove  efficient  aid  in 
English  composition;  and  the  varied  interests  of  the 
members  of  the  club,  furnish  new  and  vital  material  for 
study.  A button  or  a badge  may  be  designed  for  the  club 
and,  of  course,  it  must  have  constitution  and  by-laws. 
The  proceedings  of  the  club  meetings  should  be  conducted 
according  to  parliamentary  rules ; but  the  field  excursions 


should  be  entirely  informal. 


The  Teaching  of  Nature -Study 


2 3 


The  meetings  of  the  Junior  Naturalists  Clubs,  as  organized  in  the 
schools  of  New  York  State  by  Mr.  John  W.  Spencer,  were  most  impres- 
sive. The  school  session  would  be  brought  to  a close,  the  teacher  stepping 
down  and  taking  a seat  with  the  pupils.  The  president  of  the  club,  some 
bashful  boy  or  slender  slip  of  a girl  would  take  the  chair  and  conduct  the 
meeting  with  a dignity  and  efficiency  worthy  of  a statesman.  The  order 
was  perfect,  the  discussion  much  to  the  point.  I confess  to  a feeling  of 
awe  when  I attended  these  meetings,  conducted  so  seriously  and  so 
formally,  by  such  youngsters.  Undoubtedly,  the  parliamentary  training 
and  experience  in  speaking  impromptu,  are  among  the  chief  benefits  of 
such  a club. 

These  clubs  may  be  organized  for  special  study.  In  one  bird  club  of 
which  I know  there  have  been  contests.  Sides  were  chosen  and  the 
number  of  birds  seen  from  May  ist  to  31st  inclusive  was  the  test  of 
supremacy.  Notes  on  the  birds  were  taken  in  the  field  with  such  care, 
that  when  at  the  end  of  the  month  each  member  handed  in  his  notes,  they 
could  be  used  as  evidence  of  accurate  identification.  An  umpire  with  the 
help  of  bird  manuals  decided  the  doubtful  points.  This  year  the  score 
stood  79  to  81. 

The  programs  of  the  nature  club  should  be  varied  so  as  to  be  continually 
interesting.  Poems  and  stories,  concerning  the  objects  studied,  help 
make  the  program  attractive.

HOW  TO  USE  THIS  BOOK 

IRST  and  indispensably,  the  teacher  should  have  at 
hand  the  subject  of  the  lesson.  She  should  make 
herself  familiar  with  the  points  covered  by  the 
questions  and  read  the  story  before  giving  the  lesson. 
If  she  does  not  have  the  time  to  go  over  the  observa- 
tions suggested,  before  giving  the  lesson,  she  should 
take  up  the  questions  with  the  pupils  as  a joint 
investigation,  and  be  boon  companion  in  discover- 
ing the  story. 

The  story  should  not  be  read  to  the  pupils.  It  is  given  as  an  assistance 
to  the  teacher,  and  is  not  meant  for  direct  information  to  the  pupils.  If 
the  teacher  knows  a fact  in  nature’s  realm,  she  is  then  in  a position  to  lead 
her  pupils  to  discover  this  fact  for  themselves. 

Make  the  lesson  an  investigation  and  make  the  pupils  feel  that  they 
are  investigators.  To  tell  the  story  to  begin  with,  inevitably  spoils  this 
attitude  and  quenches  interest. 

The  “leading  thought”  embodies  some  of  the  points  which  should  be 
in  the  teacher’s  mind  while  giving  the  lesson;  it  should  not  be  read  or 
declared  to  the  pupils. 

The  outlines  for  observations  herein  given,  by  no  means  cover  all  of 
the  observations  possible;  they  are  meant  to  suggest  to  the  teacher 
observations  of  her  own,  rather  than  to  be  followed  slavishly. 

The  suggestions  for  observations  have  been  given  in  the  form  of  ques- 
tions, merely  for  the  sake  of  saving  space.  The  direct  questioning 
method,  if  not  employed  with  discretion,  becomes  tiresome  to  both  pupil 
and  teacher.  If  the  questions  do  not  inspire  the  child  to  investigate,  they 
are  useless.  To  grind  out  answers  to  questions  about  any  natural  object 
is  not  nature-study,  it  is  simply  “grind,”  a form  of  mental  activity  which 
is  of  much  greater  use  when  applied  to  spelling  or  the  multiplication  table 
than  to  the  study  of  nature.  The  best  teacher  will  cover  the  points 
suggested  for  observations  with  few  direct  questions.  To  those  who 
find  the  questions  inadequate  I will  say  that,  although  I have  used 
these  outlines  once,  I am  sure  I should  never  be  able  to  use  them  again 
without  making  changes. 

The  topics  chosen  for  these  lessons  may  not  be  the  most  practical  nor 
the  most  interesting  nor  the  most  enlightening  that  are  to  be  found ; they 
are  simply  those  subjects  which  I have  used  in  my  classes,  because  we 
happened  to  find  them  at  hand  the  mornings  the  lessons  were  given. 

While  an  earnest  attempt  has  been  made  to  make  the  information  in 
this  book  accurate,  it  is  to  be  expected  and  to  be  hoped  that  many  dis- 
crepancies will  be  found  by  those  who  follow  the  lessons.  No  two  ani- 
mals or  plants  are  just  alike,  and  no  two  people  see  things  exactly  the 
same  way.  The  chief  aim  of  this  volume  is  to  encourage  investigation 
rather  than  to  give  information.  Therefore,  if  mistakes  are  found,  the 
object  of  the  book  will  have  been  accomplished,  and  the  author  will  feel 
deeply  gratified.  If  the  teacher  finds  that  the  observations  made  by  her 
and  her  pupils,  do  not  agree  with  the  statements  in  the  book,  I earnestly 
enjoin  upon  her  to  trust  to  her  own  eyes  rather  than  to  any  book. 

No  teacher  is  expected  to  teach  all  the  lessons  in  this  book.  A wide 
range  of  subjects  is  given,  so  that  congenial  choice  may  be  made.

ANIMAL  LIFE 


I.  BIRD  STUDY 

eason  for  studying  any  bird  is  to  ascertain  what 
it  does;  in  order  to  accomplish  this,  it  is  necessary 
to  know  what  the  bird  is,  learning  what  it  is,  being 
simply  a step  that  leads  to  a knowledge  of  what 
it  does.  But,  to  hear  some  of  our  bird  devotees 
talk,  one  would  think  that  to  be  able  to  identify 
a bird  is  all  of  bird  study.  On  the  contrary,  the 
identification  of  birds  is  simply  the  alphabet  to 
the  real  study,  the  alphabet  by  means  of  which 
we  may  spell  out  the  life  habits  of  the  bird.  To 
know  these  habits  is  the  ambition  of  the  true  orni- 
thologist, and  should  likewise  be  the  ambition  of  the  beginner,  even 
though  the  beginner  be  a young  child. 

Several  of  the  most  common  birds  have  been  selected  as  subjects  for 
lessons  in  this  book;  other  common  birds,  like  the  phoebe  and  wrens,  have 
been  omitted  purposely;  after  the  children  have  studied  the  birds,  as 
indicated  in  the  lessons,  they  will  enjoy  working  out  lessons  for  them- 
selves with  other  birds.  Naturally,  the  sequence  of  these  lessons  does  not 
follow  scientific  classification;  in  the  first  ten  lessons,  an  attempt  has 
been  made  to  lead  the  child  gradually  into  a knowledge  of  bird  life. 
Beginning  with  the  chicken  there  follow  naturally  the  lessons  with 
pigeons  and  the  canary;  then  there  follows  the  careful  and  detailed  study 
of  the  robins  and  constant  comparison  of  them  with  the  blue  birds.  This 
is  enough  for  the  first  year  in  the  primary  grades.  The  next  year  the 
work  begins  with  the  birds  that  remain  in  the  North  during  the  winter, 
the  chickadee,  nuthatch  and  downy  woodpecker.  After  these  have  been 
studied  carefully,  the  teacher  may  be  an  opportunist  when  spring  comes 
and  select  any  of  the  lessons  when  the  bird  subjects  are  at  hand.  The 
classification  suggested  for  the  woodpeckers  and  the  swallows  is  for  more 
advanced  pupils,  as  are  the  lessons  on  the  geese  and  turkeys.  It  is  to 
be  hoped  that  these  lessons  will  lead  the  child  directly  to  the  use  of  the 
bird  manuals,  of  which  there  are  several  excellent  ones. 

BEGINNING  BIRD  STUDY  IN  THE  PRIMARY  GRADES 

The  hen  is  especially  adapted  as  an  object  lesson  for  the  young 
beginner  of  bird  study.  First  of  all,  she  is  a bird,  notwithstanding  the 
adverse  opinions  of  two  of  my  small  pupils  who  stoutly  maintained  that 
“a  robin  is  a bird,  but  a hen  is  a hen.”  Moreover,  the  hen  is  a bird  always 
available  for  nature-study;  she  looks  askance  at  us  from  the  crates  of  the 
world’s  marts;  she  comes  to  meet  us  in  the  country  barnyard,  stepping 
toward  us  sedately;  looking  at  us  earnestly,  with  one  eye,  then  turning  her 


26 


Handbook  of  Nature-Study 


head  so  as  to  check  up  her  observations  with  the  other;  meantime  she 
asks  us  a little  question  in  a wheedling,  soft  tone,  which  we  understand 
perfectly  to  mean  “have  you  perchance  brought  me  something  to  eat?” 
Not  only  is  the  hen  an  interesting  bird  in  herself,  but  she  is  a bird  with 
problems;  and  by  studying  her  carefully  we  may  be  introduced  into  the 
very  heart  and  center  of  bird  life. 

This  lesson  may  be  presented  in  two  ways : First,  if  the  pupils  live  in 

the  country  where  they  have  poultry  at  home,  the  whole  series  of  lessons 
may  best  be  accomplished  through  interested  talks  on  the  part  of  the 
teacher,  which  should  be  followed  on  the  part  of  the  children,  by  observa- 
tions, which  should  be  made  at  home  and  the  results  given  in  school  in 
oral  or  written  lessons.  Second,  if  the  pupils  are  not  familiar  with  fowls, 
a hen  and  a chick,  if  possible,  should  be  kept  in  a cage  in  the  schoolroom 
for  a few  days,  and  a duck  or  gosling  should  be  brought  in  one  day  for 
observation.  The  crates  in  which  fowls  are  sent  to  market  make  very 
good  cages.  One  of  the  teachers  of  the  Elmira,  N.  Y.  Schools  introduced 
into  the  basement  of  the  schooihouse  a hen,  which  there  hatched  her 
brood  of  chicks,  much  to  the  children’s  delight  and  edification.  After  the 
pupils  have  become  thoroughly  interested  in  the  hen  and  are  familiar  with 
her  ways,  after  they  have  fed  her  and  watched  her,  and  have  for  her  a 
sense  of  ownership,  the  following  lessons  may  be  given  in  an  informal 
manner,  as  if  they  were  naturally  suggested  to  the  teacher’s  mind  through 
watching  the  fowl.

Bird  Study 


FEATHERS  AS  CLOTHING 

Teacher's  Story 

HE  bird’s  clothing  affords  a natural  beginning  for  bird 
study  because  the  wearing  of  feathers  is  a most  strik- 
ing character  distinguishing  birds  from  other  crea- 
tures; also,  feathers  and  flying  are  the  first  things 
the  young  child  notices  about  birds. 

The  purpose  of  all  of  these  lessons  on  the  hen  are:  (a)  To  induce  the 

child  to  make  continued  and  sympathetic  observations  on  the  habits  of. 
the  domestic  birds,  (b)  To  cause  him  involuntarily  to  compare  the 
domestic  with  the  wild  birds,  (c)  To  induce  him  to  think  for  himself  why 
the  shape  of  the  body,  wings,  head,  beak,  feet,  legs  and  feathers  are 
adapted  in  each  species  to  protect  the  bird  and  assist  it  in  getting  its 
living. 

The  overlapping  of  the  feathers  on  a hen’s  back  and  breast  is  a pretty 
illustration  of  nature’s  method  of  shingling,  so  that  the  rain,  finding  no 
place  to  enter,  drips  off,  leaving  the  bird’s  underclothing  quite  dry.  It 
is  interesting  to  note  how  a hen  behaves  in  the  rain ; she  droops  her  tail 
and  holds  herself  so  that  the  water  finds  upon  her  no  resting  place,  but 


simply  a steep  surface  down  which  to  flow  to  the  ground. 

Each  feather  consists  of 
three  parts,  the  shaft  or  quill, 
which  is  the  central  stiff  stem 
of  the  feather,  giving  it 
strength.  From  this  quill 
come  off  the  barbs  which, 
toward  the  outer  end,  join  to- 
gether in  a smooth  web,  mak- 
ing the  thin,  fan-like  portion 
of  the  feather ; at  the  base  is 
the  fluff,  which  is  soft  and 
downy  and  near  to  the  body 
of  the  fowl.  The  teacher 
should  put  on  the  blackboard 
this  figure  so  that  incidentally 
the  pupils  may  learn  the  parts 
of  a feather  and  their  struc- 
t u r e . If  a microscope  is 
available,  show  both  the  web 
and  the  fluff  of  a feather  under  a three- fourths  objective. 

The  feathers  on  the  back  of  a hen  are  longer  and  narrower  in  propor- 
tion than  those  on  the  breast  and  are  especially  fitted  to  protect  the  back 
from  rain ; the  breast  feathers  are  shorter  and  have  more  of  the  fluff,  thus 
protecting  the  breast  from  the  cold  as  well  as  the  rain.  It  is  plain  to  any 
child  that  the  soft  fluff  is  comparable  to  our  woolen  underclothing  while 
the  smooth,  overlapping  web  forms  a rain  and  wind-proof  outer  coat. 
Down  is  a feather  with  no  quill ; young  chicks  are  covered  with  down.  A 
pin-feather  is  simply  a young  feather  rolled  up  in  a sheath,  which  bursts 
later  and  is  shed,  leaving  the  feather  free  to  assume  its  form.  Take  a 
large  pin-feather  and  cut  the  sheath  open  and  show  the  pupils  the  young 
feather  lying  within.

Handbook  of  N ature-Study 


When  a hen  oils  her  feathers  it  is  a process  well  worth  observing.  The 
oil  gland  is  on  her  back  just  at  the  base  of  the  tail  feathers;  she  squeezes 
the  gland  with  her  beak  to  get  the  oil  and  then  rubs  the  beak  over  the  sur- 
face of  her  feathers  and  passes  them  through  it;  she  spends  more  time 
oiling  the  feathers  on  her  back  and  breast  than  those  on  the  other  parts, 
so  that  they  will  surely  shed  water.  Country  people  say  when  the  hen 
oils  her  feathers,  it  is  a sure  sign  of  rain.  The  hen  sheds  her  feathers  once 
a year  and  is  a most  untidy  looking  bird  meanwhile,  a fact  that  she  seems 
to  realize,  and  is  as  shy  and  cross  as  a young  lady  caught  in  company  in 
curl  papers;  but  she  seems  very  pleased  with  herself  when  she  finally 
gains  her  new  feathers.

Bird  Study 
LESSON  I 

Feathers  as  Clothing 

Leading  thought — Feathers  grow  from  the  skin  of  a bird  and  protect 
the  bird  from  rain,  snow,  wind  and  cold.  Some  of  the  feathers  act  as 
cloaks  or  mackintoshes  and  others  as  underclothing. 

Method — The  hen  should  be  at  close  range  for  this  lesson  where  the 
children  may  observe  how  and  where  the  different  kinds  of  feathers  grow. 
The  pupils  should  also  study  separately  the  form  of  a feather  from  the 
back,  from  the  breast,  from  the  under  side  of  the  body,  and  a pin-feather. 

Observations  for  pupils — i.  How  are  the  feathers  arranged  on  the 
back  of  the  hen ? Are  they  like  shingles  on  the  roof?  If  so,  what  for? 

2.  How  does  a hen  look  when  standing  in  the  rain? 

3.  How  are  the  feathers  arranged  on  the  breast? 

4.  Compare  a feather  from  the  back  and  one  from  the  breast  and 
note  the  difference. 

5.  Are  both  ends  of  these  feathers  alike?  If  not,  what  is  the 
difference  ? 

6.  Is  the  fluffy  part  of  the  feather  on  the  outside  or  next  to  the 
bird’s  skin  ? What  is  its  use  ? 

7.  Why  is  the  smooth  part  of  the  feather  (the  web)  on  the  outside? 

8.  Some  feathers  are  all  fluff  and  are  called  “down.”  At  what  age 
was  the  fowl  all  covered  with  down  ? 

9.  What  is  a pin-feather?  What  makes  you  think  so? 

10.  How  do  hens  keep  their  feathers  oily  and  glossy  so  they  will 
shed  water? 

11.  Where  does  the  hen  get  the  oil?  Describe  how  she  oils  her 
feathers  and  which  ones  does  she  oil  most?  Does  she  oil  her  feathers 
before  a rain  ? 


“ How  beautiful  your  feathers  be!” 

The  Redbird  sang  to  the  Tulip-tree 
New  garbed  in  autumn  gold. 

“Alas!”  the  bending  branches  sighed, 

‘‘They  cannot  like  your  leaves  abide 
To  keep  us  from  the  cold!”

FEATHERS  AS  ORNAMENT 
Teacher's  Story 

HE  ornamental  plumage  of  birds  is  one  of  the 
principal  illustrations  of  a great  principle  of  evo- 
lution. The  theory  is  that  the  male  birds  win 
their  mates  because  of  their  beauty,  those  that 
are  not  beautiful  being  doomed  to  live  single 
and  leave  no  progeny  to  inherit  their  dullness. 
On  the  other  hand,  the  successful  wooer  hands 
down  his  beauty  to  his  sons.  However,  another 
quite  different  principle  acts  upon  the  coloring 
of  the  plumage  of  the  mother  birds;  for  if  they  should  develop 
bright  colors  themselves,  they  would  attract  the  eyes  of  the  enemy 
to  their  precious  hidden  nests;  only  by  being  inconspicuous,  are 
they  able  to  protect  their  eggs  and  nestlings  from  discovery  and 
death.  The  mother  partridge,  for  instance,  is  so  nearly  the  color  of  the 
dead  leaves  on  the  ground  about  her,  that  we  may  almost  step  upon  her 
before  we  discover  her;  if  she  were  the  color  of  the  oriole  or  tanager  she 
would  very  soon  be  the  center  of  attraction  to  every  prowler.  Thus,  it 
has  come  about  that  among  the  birds  the  feminine  love  of  beauty  has 
developed  the  gorgeous  colors  of  the  males,  while  the  need  for  protection 
of  the  home  has  kept  the  female  plumage  modest  and  unnoticeable. 

The  curved  feathers  of  the  rooster’s  tail  are  weak  and  mobile  and 
could  not  possibly  be  of  any  use  as  a rudder;  but  they  give  grace  and 
beauty  to  the  fowl  and  cover  the  useful  rudder  feathers  underneath  by  a 
feather  fountain  of  iridescence.  The  neck  plumage  of  the  cock  is  also 
often  luxurious  and  beautiful  in  color  and  quite  different  from  that  of  the 
hen.  Among  the  ducks  the  brilliant  blue-green  iridescent  head  of  the 
drake  and  his  wing  bars  are  beautiful,  and  make  his  wife  seem  Quaker-like 
in  contrast. 

As  an  object  lesson  to  instil  the  idea  that  the  male  bird  is  proud  of  his 
beautiful  feathers,  I know  of  none  better  than  that  presented  by  the 
turkey  gobbler,  for  he  is  a living  expression  of  self-conscious  vanity.  He 
spreads  his  tail  to  the  fullest  extent  and  shifts  it  this  way  and  that  to  show 
the  exquisite  play  of  colors  over  the  feathers  in  the  sunlight,  meanwhile 
throwing  out  his  chest  to  call  particular  attention  to  his  blue  and  red 
wattles;  and  to  keep  from  bursting  with  pride  he  bubbles  over  in  vain- 
glorious “gobbles.” 

The  hen  with  her  chicks  and  the  turkey  hen  with  her  brood,  if  they 
follow  their  own  natures,  must  wander  in  the  fields  for  food.  If  they 
were  bright  in  color,  the  hawks  would  soon  detect  them  and  their  chances 
of  escape  would  be  small ; this  is  another  instance  of  the  advantage  to  the 
young  of  adopting  the  colors  of  the  mother  rather  than  of  the  father;  a 
fact  equally  true  of  the  song  birds  in  cases  where  the  males  are  brilliant  in 
color  at  maturity.  The  Baltimore  oriole  does  not  assist  his  mate  in 
brooding,  but  he  sits  somewhere  on  the  home  tree  and  cheers  her  by  his 
glorious  song  and  by  glimpses  of  his  gleaming  orange  coat.  Some  have 
accused  him  of  being  lazy;  on  the  contrary,  he  is  a wise  householder  for, 
instead  of  attracting  the  attention  of  crow  or  squirrel  to  his  nest,  he  dis- 
tracts their  attention  from  it  by  both  color  and  song. 

A peacock’s  feather  should  really  be  a lesson  by  itself,  it  is  so  much  a 
thing  of  beauty.  The  brilliant  color  of  the  purple  eye-spot,  and  the  grace- 


Bird  Study

ful  flowing  barbs  that  form  the  setting  to  the  central  gem,  are  all 
a training  in  aesthetics  as  well  as  in  nature-study.  After  the 
children  have  studied  such  a 
feather  let  them  see  the  peacock 
either  in  reality  or  in  picture 
and  give  them  stories  about  this 
bird  of  Juno;  a bird  so  incon- 
spicuous if  it  were  not  for  his 
great  spread  of  tail,  that  a child 
seeing  it  first  cried,  “Oh,  oh,  see 
this  old  hen  all  in  bloom!” 

The  whole  question  of  sexual 
selection  may  be  made  as  plain 
as  need  be  for  the  little  folks,  by 
simply  telling  them  that  the 
mother  bird  chooses  for  her  mate  the  one  which  is  most  brightly  and 
beautifully  dressed,  and  make  much  of  the  comb  and  wattles  of  the 
rooster  and  gobbler  as  additions  to  the  brilliancy  of  their  appearance. 


Peacock  feathers.  Is  beauty  useful? 


LESSON  II 

Feathers  as  Ornament 

Leading  thought — The  color  of  feathers  and  often  their  shape  are  for  the 
purpose  of  making  birds  more  beautiful ; while  in  others,  the  color  of  the 
feathers  protects  them  from  the  observation  of  their  enemies. 

Methods — While  parts  of  this  lesson  relating  to  fowls,  may  be  given  in 
primary  grades,  it  is  equally  fitted  for  pupils  who  have  a wider  knowledge 
of  birds.  Begin  with  a comparison  of  the  plumage  of  the  hen  and  the 
rooster.  Then,  if  possible,  study  the  turkey  gobbler  and  a peacock  in  life 
or  in  pictures.  Also  the  plumage  of  a Rouen  duck  and  drake,  and  if 
possible,  the  Baltimore  oriole,  the  goldfinch,  the  scarlet  tanager  and 
the  cardinal. 

Observations — 1.  Note  difference  in  shape  and  coloj  of  the  tail 
feathers  of  hen  and  rooster. 

2.  Do  the  graceful  curved  tail  feathers  of  the  rooster  help  him  in 
flying?  Are  they  stiff  enough  to  act  as  a rudder? 

3.  If  not  of  use  in  flying  what  are  they  for?  Which  do  you  think 
the  more  beautiful  the  hen  or  the  rooster? 

4.  In  what  respects  is  the  rooster  a more  beautiful  fowl? 

5.  What  other  parts  of  the  rooster’s  plumage  is  more  beautiful  than 
that  of  the  hen  ? 

6.  If  a turkey  gobbler  sees  you  looking  at  him  he  begins  to  strut. 
Do  you  think  he  does  this  to  show  off  his  tail  feathers?  Note  how  he 
turns  his  spread  tail  this  way  and  that  so  the  sunshine  will  bring  out  the 
beautiful  changeable  colors.  Do  you  think  he  does  this  so  }rou  can  see 
and  admire  him  ? 

7.  Describe  the  difference  in  plumage  between  the  hen  turkey  and 
the  gobbler?  Does  the  hen  turkey  strut? 

8.  Note  the  beautiful  blue-green  iridescent  head  and  wing  patches 


32  Handbook  of  Nature-Study 

on  the  wings  of  the  Rouen  ducks  ? Is  the  drake  more  beautiful  than  the 
duck? 

9.  What  advantage  is  it  for  these  fowls  to  have  the  father  bird 
more  beautiful  and  bright  in  color  than  the  mother  bird  ? 

10.  In  case  of  the  Baltimore  oriole  is  the  mother  bird  as  bright  in 
color  as  the  father  bird?  Why? 

11.  Study  a peacock’s  feather.  What  color  is  the  eye-spot?  What 
color  around  that?  What  color  around  that ? What  color  and  shape  are 
the  outside  barbs  of  the  feather?  Do  you  blame  a peacock  for  being 
proud  when  he  can  spread  a tail  of  a hundred  eyes?  Does  the  peahen 
have  such  beautiful  tail  feathers  as  the  peacock? 


Peahens  and  peacocks 


The  bird  of  Juno  glories  in  his  plumes; 

Pride  makes  the  fowl  to  preene  his  feathers  so. 

His  spotted  train  fetched  from  old  Argus'  head , 

With  golden  rays  like  to  the  brighest  sun, 

Inserteth  self-love  in  the  silly  bird; 

Till  midst  its  hot  and  glorious  fumes 
He  spies  his  feet  and  then  lets  fall  his  plumes.

HOW  BIRDS  FLY 

Teacher's  Story 

TO  convince  the  children  that  a bird’s  wings  correspond 
to  our  arms,  they  should  see  a fowl  with  its  feathers  off, 
prepared  for  market  or  oven,  and  they  will  infer  the 
fact  at  once. 

The  bird  flies  by  lifting  itself  through  pressing  down  upon  the  air  with 
its  wings.  There  are  several  experiments  which  are  needed  to  make  the 
child  understand  this.  It  is  difficult  for  children  to  conceive  that  the  air 
is  really  anything,  because  they  cannot  see  it;  so  the  first  experiment 
should  be  to  show  that  the  air  is  something  we  can  push  against  or  that 
pushes  against  us.  Strike  the  air  with  a fan  and  we  feel  there  is  something 
which  the  fan  pushes ; we  feel  the  wind  when  it  is  blowing  and  it  is  very 
difficult  for  us  to  walk  against  a hard  wind.  If  we  hold  an  open  umbrella 
in  the  hand  while  we  jump  from  a step  we  feel  buoyed  up  because  the 
umbrella  presses  down  upon  the  air.  The  bird  presses  down  upon  the  air 
with  the  wings,  just  as  the  open  umbrella  does.  The  bird  flies  by  pressing 
down  upon  the  air  with  its  wings  just  as  a boy  jumps  high  by  pressing 
down  with  his  hands  on  his  vaulting  pole.

Handbook  of  Nature-Study 


Study  wing  and  note : (a)  That  the  wings  open  and  close  at  the 
will  of  the  bird,  (b)  That  the  feathers  open  and  shut  on  each  other  like  a 
fan.  (c)  When  the  wing  is  open  the  wing  quills  overlap,  so  that  the  air 
cannot  pass  through  them,  (d)  When  the  wing  is  open  it  is  curved  so 
that  it  is  more  efficient,  for  the  same  reason  that  an  umbrella  presses 
harder  against  the  atmosphere  when  it  is  open  than  when  it  is  broken  by 
the  wind  and  turned  wrong  side  out. 

A wing  feather  has  the  barbs  on  the  front  edge  lying  almost  parallel  to 
the  quill  while  those  on  the  hind  edge  come  off  at  a wide  angle.  The 
reason  for  this  is  easy  to  see,  for  this  feather  has  to  cut  the  air  as  the  bird 
flies;  and  if  the  barbs  on  the  front  side  were  like  those  of  the  other  side 
they  would  be  tom  apart  by  the  wind.  The  barbs  on  the  hind  side  of  the 
feather  form  a strong,  close  web  so  as  to  press  down  on  the  air  and  not  let 
it  through.  The  wing  quill  is  curved;  the  convex  side  is  up  and  the  con- 
cave side  below  during  flight.  The  concave  side,  like  the  umbrella, 
catches  more  air  than  the  upper  side ; the  down  stroke  of  the  wing  is  for- 
ward and  down;  while  on  the  up  stroke,  as  the  wing  is  lifted,  it  bends  at 
the  joint  like  a fan  turned  sidewise,  and  offers  less  surface  to  resist  the  air. 
Thus,  the  up  stroke  does  not  push  the  bird  down. 

Observations  should  be  made  on  the  use  of  the  bird’s  tail  in  flight. 
The  hen  spreads  her  tail  like  a fan  when  she  flies  to  the  top  of  the  fence; 
the  robin  does  likewise  when  in  flight.  The  fact  that  the  tail  is  used  as  a 
rudder  to  guide  the  bird  in  flight,  as  well  as  to  give  more  surface  for 
pressing  down  upon  the  air,  is  hard  for  the  younger  pupils  to  understand, 
and  perhaps  can  be  best  taught  by  watching  the  erratic  unbalanced  flight 
of  young  birds  whose  tail  feathers  are  not  yet  grown. 

The  tail  feather  differs  from  the  wing  feather  in  that  the  quill  is  not 
curved,  and  the  barbs  on  each  side  are  of  about  equal  length  and  lie  at 
about  the  same  angle  on  each  side  the  quill.  See  Fig.  p.  28.

LESSON  III. 

How  Birds  Fly 

Leading  thought — A bird  flies  by  pressing  down  upon  the  air  with  its 
wings,  which  are  made  especially  for  this  purpose.  The  bird’s  tail  acts  as 
a rudder  during  flight. 

Method — The  hen,  it  is  hoped  will  by  this  time  be  tame  enough  so  that 
the  teacher  may  spread  open  her  wings  for  the  children  to  see.  In  addi- 
tion, have  a detached  wing  of  a fowl  such  as  are  used  in  farm  houses 
instead  of  a whisk-broom. 

Observations — 1.  Do  you  think  a bird’s  wings  correspond  to  our 
arms?  If  so  why? 

2.  Why  do  birds  flap  their  wings  when  they  start  to  fly? 

3 . Can  you  press  against  the  air  with  a fan  ? 

4.  Why  do  you  jump  so  high  with  a vaulting  pole?  Do  you  think 
the  bird  uses  the  air  as  you  use  the  pole? 

5 . How  are  the  feathers  arranged  on  the  wing  so  that  the  bird  can 
use  it  to  press  down  on  the  air?

6.  If  you  carry  an  umbrella  on  a windy  morning,  which  catches 
more  wind,  the  under  or  the  top  side?  Why  is  this?  Does  the  curved 
surface  of  the  wing  act  in  the  same  way  ? 

7.  Take  a wing  feather.  Are  the  barbs  as  long  on  one  side  of  the 
quill  as  on  the  other?  Do  they  lie  at  the  same  angle  from  the  quill  on 
both  sides  ? If  not  why  ? 

8.  Which  side  of  the  quill  lies  on  the  outer  side  and  which  on  the 
inner  side  of  the  wing? 

9.  Is  the  quill  of  the  feather  curved? 

10.  Which  side  is  uppermost  in  the  wing,  the  convex  or  the  concave 
side?  Take  a quill  in  one  hand  and  press  the  tip  against  the  other. 
Which  way  does  it  bend  easiest,  toward  the  convex  or  the  concave  side? 
What  had  this  to  do  with  the  flight  of  the  bird  ? 

11.  If  the  bird  flies  by  pressing  the  wings  against  the  air  on 
the  down  stroke,  why  does  it  not  push  itself  downward  with  its 
wings  on  the  up  stroke  ? 

12.  What  is  the  shape  and  arrangement  of  the  feathers  so  as  to 
avoid  pushing  the  bird  back  to  earth  when  it  lifts  its  wings  ? 

13.  Why  do  you  have  a rudder  to  a boat? 

14.  Do  you  think  a bird  could  sail  through  the  air  without  some- 
thing to  steer  with?  What  is  the  bird’s  rudder? 

15.  Have  you  ever  seen  a young  bird  whose  tail  is  not  yet  grown, 
try  to  fly?  If  so,  how  did  it  act? 

16.  Does  the  hen  when  she  flies  keep  the  tail  closed  or  open  like 
a fan? 

17.  Compare  a tail  feather  with  a wing  feather  and  describe  the 
difference.

EYES  AND  EARS  OF  BIRDS 
Teacher's  Story 

HE  hen’s  eyes  are  placed  at  the  side  of  the  head  so  that 
she  cannot  see  the  same  object  with  both  eyes  at  the 
same  time,  and  thus  she  has  the  habit  of  looking  at  us 
first  with  one  eye  and  then  the  other  to  be  sure  she 
sees  correctly;  also  the  position  of  the  hen’s  eyes  give 
her  a command  of  her  entire  environment.  All  birds 
have  much  keener  eyes  than  have  we;  and  they  can 
adjust  their  eyes  for  either  near  or  far  vision  much 
more  effectively  than  we  can ; the  hawk,  flying  high  in  the  air,  can  see 
the  mouse  on  the  ground. 

There  is  a wide  range  of  colors  found  in  the  eyes  of  birds;  white,  red 
blue,  yellow,  brown,  gray,  pink,  purple  and  green  are  found  in  the  iris  of 
different  species.  The  hen’s  eye  consists  of  a black  pupil  at  the  center, 
which  must  always  be  black  in  any  eye,  since  it  is  a hole  through  which 
enters  the  image  of  the  object.  The  iris  of  the  hen’s  eye  is  yellow;  there 
is  apparently  no  upper  lid  but  the  lower  lid  comes  up  during  the  process  of 
sleeping.  When  the  bird  is  drowsy  the  little  film  lid  comes  out  from  the 
corner  of  the  eye  and  spreads  over  it  like  a veil;  just  at  the  comer  of  our 
own  eye,  next  the  nose,  is  the  remains  of  this  film  lid,  although  we  cannot 
move  it  as  the  hen  does. 

The  hearing  of  birds  is  very  acute,  although  the  ear  is  simply  a hole  in 
the  side  of  the  head  in  most  cases,  and  is  more  or  less  covered  with 
feathers.  The  hen’s  ear  is  like  this  in  many  varieties;  but  in  others  and 
in  the  roosters  there  are  ornamental  ear  lobes. 


LESSON  IV 

Eyes  and  Ears  of  Birds 

Leading  thought — The  eyes  and  ears  of  birds  are  peculiar  and  very 
efficient. 

Methods — The  hen  or  chicken  and  the  rooster  should  be  observed  for 
this  lesson ; notes  may  be  made  in  the  poultry  yard  or  in  the  schoolroom 
when  the  birds  are  brought  there  for  study. 

Observations — i . Why  does  the  hen  turn  her  head  first  this  side  and 
that  as  she  looks  at  you?  Can  she  see  an  object  with  both  eyes  at  once? 
Can  she  see  well? 

2.  How  many  colors  are  there  in  a hen’s  eye?  Describe  the  pupil 
and  the  iris. 

3.  Does  the  hen  wink  as  we  do?  Has  she  any  eyelids? 

4.  Can  you  see  the  film  lid?  Does  it  come  from  above  or  below  or 
the  inner  or  outer  comer?  When  do  you  see  this  film  lid? 

5.  Where  are  the  hen’s  ears?  How  do  they  look?  How  can  you 
tell  where  the  rooster’s  ears  are? 

6.  Do  you  think  the  hen  can  see  and  hear  well  ? 


Bird  Study  3 7 

THE  FORM  AND  USE  OF  BEAKS 

Teacher's  Story 

INCE  the  bird  uses  its  arms  and  hands  for  flying,  it 
has  been  obliged  to  develop  other  organs  to  take 
their  place,  and  of  their  work  the  beak  does  its  full 
share.  It  is  well  to  emphasize  this  point  by  letting 
the  children  at  recess  play  the  game  of  trying  to  eat 
an  apple  or  to  put  up  their  books  and  pencils  with 
their  arms  tied  behind  them;  such  an  experiment 
will  show  how  naturally  the  teeth  and  feet  come  to  the  aid  when  the 
hands  are  useless. 

The  hen  feeds  upon  seeds  and  insects  which  she  finds  on  or  in  the 
ground;  her  beak  is  horny  and  sharp  and  acts  not  only  as  a pair  of  nip- 
pers, but  also  as  a pick  as  she  strikes  it  into  the  soil  to  get  the  seed  or 
insect,  having  already  made  bare  the  place  by  scratching  away  the  grass 
or  surface  of  the  soil  with  her  strong,  stubby  toes.  The  hen  does  not  have 
any  teeth,  nor  does  she  need  any,  for  her  sharp  beak  enables  her  to  seize 
her  food;  and  she  does  not  need  to  chew  it,  since  her  gizzard  does  this  for 
her  after  the  food  is  swallowed. 

The  duck’s  bill  is  broad,  flat,  and  much  softer  than  the  hen’s  beak. 
The  duck  feeds  upon  water  insects  and  plants ; it  attains  these  by  thrust- 
ing its  head  down  into  the  water,  seizing  the  food  and  holding  it  fast  while 
the  water  is  strained  out  through  the  sieve  at  the  edges  of  the  beak;  for 
this  use,  a wide,  flat  beak  is  necessary.  It  would  be  quite  as  impossible 
for  a duck  to  pick  up  hard  seeds  with  its  broad,  soft  bill  as  it  would  for 
the  hen  to  get  the  duck’s  food  out  of  the  water  with  her  narrow,  horny 
bill. 

Both  the  duck  and  hen  use  their  bills  for  cleaning  and  oiling  their 
feathers  and  for  fighting  also ; the  hen  strikes  a sharp  blow  with  her  beak 
making  a wound  like  a dagger,  while  the  duck  seizes  the  enemy  and 
simply  pinches  hard.  Both  fowls  also  use  their  beaks  for  turning  over  the 
eggs  when  incubating,  and  also  as  an  aid  to  the  feet  when  they  make  nests 
for  themselves. 

The  nostrils  are  very  noticeable  and  are  situated  in  the  beak  near  the 
base.  However,  we  do  not  believe  that  birds  have  a keen  sense  of  smell 
since  their  nostrils  are  not  surrounded  by  a damp,  sensitive,  soft  surface 
as  are  the  nostrils  of  the  deer  and  dog,  this  arrangement  aiding  these 
animals  to  detect  odor  in  a marvelous  manner. 

LESSON  V 
The  Beak  of  a Bird 

Leading  thought — Each  kind  of  bird  has  a beak  especially  adapted  for 
getting  its  food.  The  beak  and  feet  of  a bird  are  its  chief  weapons  and 
implements. 

Methods — Study  first  the  beak  of  the  hen  or  chick  and  then  that  of 
the  duckling  or  gosling. 

Observations — 1.  What  kind  of  food  does  the  hen  eat  and  where  and 
how  does  she  find  it  in  the  field  or  gaiden?  How  is  her  beak  adapted  to 
get  this  food?  If  her  beak  were  soft  like  that  of  a duck  could  she  peck  so 
hard  for  seeds  and  worms  ? Has  the  hen  any  teeth  ? Does  she  need  any  ?

2.  Compare  the  bill  of  the  hen  with  that  of  the  duck?  What  are 
the  differences  in  shape?  Which  is  the  harder? 

3.  Note  the  saw  teeth  along  the  edge  of  the  duck’s  bill.  Are  these 
for  chewing?  Do  they  act  as  a strainer?  Why  does  the  duck  need  to 
strain  its  food  ? 

4.  Could  a duck  pick  up  a hen’s  food  from  the  earth  or  the  hen 
strain  out  a duck’s  food  from  the  water?  For  what  other  things  than 
getting  food  do  these  fowls  use  their  bills? 

5.  Can  you  see  the  nostrils  in  the  bill  of  a hen?  Do  they  show 
p’ainer  in  the  duck?  Do  you  think  the  hen  can  smell  as  keenly  as  the 
duck?

11  It  is  said  that  nature- study  teaching  should  be  accurate , a statement  that  every  good 
teacher  will  admit  without  debate;  but  accuracy  is  often  interpreted  to  mean  complete- 
ness, and  then  the  statement  cannot  pass  unchallenged.  To  study  ‘the  dandelion,'  ‘the 
robin,'  with- emphasis  on  the  particle  ‘the' , working  out  %he  complete  structure,  may  be 
good  laboratory  work  in  botany  or  zoology  for  advanced  pupils,  but  it  is  not  an  elemen- 
tary educational  process.  It  contributes  nothing  more  to  accuracy  than  does  the  natural 
order  of  leaving  untouched  all  those  phases  of  the  subject  that  are  out  of  the  child's  reach; 
while  it  may  take  out  the  life  and  spirit  of  the  work,  and  the  spiritual  quality  may  be 
the  very  part  that  is  most  worth  the  while.  Other  work  may  provide  the  formal  ‘drill' ; 
this  should  supply  the  quality  and  vivacity.  Teachers  often  say  to  me  that  their 
children  have  done  excellent  work  with  these  complete  methods,  and  they  show  me  the 
essays  and  drawings;  but  this  is  no  proof  that  the  work  is  commendable.  Children 
can  be  made  to  do  many  things  that  they  ought  not  to  do  and  that  lie  beyond  them.  We 
all  need  to  go  to  school  to  children." — “The  Outlook  to  Nature,”  L.  H.  Bailey.

THE  FEET  OF  BIRDS 

Teacher's  Story 

BVIOUSLY,  the  hen  is  a digger  of  the  soil;  her  claws 
are  long,  strong  and  slightly  hooked,  and  her  feet 
and.  legs  are  covered  with  homy  scales  as  a protec- 
tion from  injury  when  used  in  scratching  the  hard 
earth,  in  order  to  lay  bare  the  seeds  and  insects 
hiding  there.  The  hen  is  a very  good  runner  indeed. 
She  lifts  her  wings  a little  to  help,  much  as  an 
athletic  runner  uses  his  arms,  and  so  can  cover 
ground  with  amazing  rapidity,  her  strong  toes  giv- 
ing her  a firm  foothold.  The  track  she  makes  is 
very  characteristic;  it  consists  of  three  toe-marks 
projecting  forward  and  one  backward.  A bird’s 
toes  are  numbered  thus: 

A duck 

has  the  same  number  of  toes  as 
the  hen,  but  there  is  a membrane, 
called  the  web,  which  joins  the 
second,  third  and  fourth  toes,  mak- 
ing a fan-shaped  foot ; the  first  or 
the  hind  toe  has  a little  web  of  its 
own.  A webbed  foot  is  first  of  all 
a paddle  for  propelling  its  owner 
through  the  water;  it  is  also  a very  useful  foot  on  the  shores  of  ponds 
and  streams,  since  its  breadth  and  flatness  prevent  it  from  sinking  into 
the  soft  mud. 

The  duck’s  legs  are  shorter  than  those  of  the  hen  and  are  placed  farther 
back  and  wider  apart.  The  reason  for  this  is,  they  are  essentially  swim- 
ming organs  and  are  not  fitted  for  scratching  nor  for  running.  They  are 
placed  at  the  sides  of  the  bird’s  body  so  that  they  may  act  as  paddles,  and 
are  farther  back  so  that  they  may  act  like  the  wheel  of  a propeller  in

pushing  the  bird  along.  We  often  laugh  at  a duck  on  land,  since  its  short 
legs  are  so  far  apart  and  so  far  back  that  its  walk  is  necessarily  an  awk- 
ward waddle;  but  we  must  always  remember  that  the  duck  is  naturally 
a water  bird,  and  on  the  water  its  movements  are  graceful.  Think  once, 
how  a hen  would  appear  if  she  attempted  to  swim!  The  duck’s  body  is 
so  illy  balanced  on  its  short  legs  that  it  cannot  run  rapidly;  and  if  chased 
even  a short  distance,  will  fall  dead  from  the  effort,  as  many  a country 
child  has  discovered  to  his  sorrow  when  he  tried  to  drive  the  ducks  home 
from  the  creek  or  pond  to  coop.  The  long,  hind  claw  of  the  hen  enables 
her  to  clasp  a roost  firmly  during  the  night;  a duck’s  foot  could  not  do 
this  and  the  duck  sleeps  squatting  on  the  ground.  However,  the  Mus- 
covy ducks,  which  are  not  good  swimmers,  have  been  known  to  perch. 


LESSON  VI 
The  Feet  of  Birds 

Leading  thought — The  feet  of'  birds  are  shaped  so  as  to  assist  the  bird  in 
getting  its  food  as  well  as  for  locomotion. 

Methods — The  pupils  should  have  opportunity  to  observe  the  chicken 
or  hen  and  a duck  as  they  move  about;  they  should  also  observe  the 
duck  swimming. 

Observations — i.  Are  the'  toes  of  the  hen  long  and  strong?  Have 
they  long,  sharp  claws  at  their  tips? 

2.  How  are  the  legs  and  feet  of  the  hen  covered  and  protected? 

3.  How  are  the  hen’s  feet  and  legs  fitted  for  scratching  the  earth, 
and  why  does  she  wish  to  scratch  the  earth? 

4.  Can  a hen  run  rapidly?  What  sort  of  a track  does  she  make? 

5.  You  number  your  fingers  with  the  thumb  as  number  one  and  the 
little  finger  as  five.  How  do  you  think  the  hen’s  toes  are  numbered? 

6.  Has  the  duck  as  many  toes  as  the  hen?  What  is  the  chief 
difference  between  the  feet  of  the  duck  and  the  hen  ? 

7.  Which  of  the  duck’s  toes  are  connected  by  a web?  Does  the 
web  extend  to  the  tips  of  the  toes  ? What  is  the  web  for  and  how  does  it 
help  the  duck  ? 

8.  Are  the  duck’s  legs  as  long  as  the  hen’s?  Are  they  placed 
farther  forward  or  farther  back  than  those  of  the  hen  ? Are  they  farther 
apart? 

9.  Can  a duck  run  as  well  as  a hen?  Can  the  hen  swim  at  all? 

10.  Where  does  the  hen  sleep  and  how  does  she  hold  on  to  her 
perch?  Could  the  duck  hold  on  to  a perch?  Does  the  duck  need  to 
perch  while  sleeping?

CHICKEN  WAYS 
Teacher's  Story 

AME  Nature  certainly  pays  close  attention  to  details, 
and  an  instance  of  this  is  the  little  tooth  on  the  tip  of 
the  upper  mandible  of  the  young  chick  to  aid  it  in 
breaking  out  of  its  egg-shell  prison ; and  since  a tooth 
in  this  particular  place  is  of  no  use  later,  it  disappears. 
The  children  are  delighted  with  the  beauty  of  a fluffy, 
little  chick  with  its  bright,  questioning  eyes  and  its  life 
of  activity  as  soon  as  it  is  freed  from  the  shell.  What 
a contrast  to  the  blind,  bare,  scrawny  young  robin, 
which  seems  to  be  all  mouth ! The  difference  between 
the  two  is  fundamental  since  it  gives  a character  for  separating  ground 
birds  from  perching  birds.  The  young  partridge,  quail,  turkey  and  chick 
are  clothed  and  active  and  ready  to  go  with  the  mother  in  search  of  food 
as  soon  as  they  are  hatched ; while  the  young  of  the  perching  birds  are 
naked  and  blind,  being  kept  warm  by  the  brooding  mother,  and  fed  and 
nourished  by  food  brought  by  their  parents,  until  they  are  large  enough  to 
leave  the  nest.  The  down  which  covers  the  young  chick  differs  from  the 
feathers  which  come  later;  the  down  has  no  quill  but  consists  of  several 
flossy  threads  coming  from  the  same  root;  later  on,  this  down  is  pushed 
out  and  off  by  the  true  feathers  which  grow  from  the  same  sockets.  The 


An  anxious  stepmother. 


42 


Handbook  of  Nature-Study 


pupils  should  see  that  the  down  is  so  soft  that  the  little,  fluffy  wings  of  the 
chick  are  useless  until  the  real  wing  feathers  appear. 

We  chew  food  until  it  is  soft  and  fine,  then  swallow  it,  but  the  chick 
swallows  it  whole  and  after  being  softened  by  juices  from  the  stomach  it 
passes  into  a little  mill,  in  which  is  gravel  that  the  chicken  has  swallowed, 
which  helps  to  grind  the  food.  This  mill  is  Called  the  gizzard  and  the 
pupils  should  be  taught  to  look  carefully  at  this  organ  the  next  time  they 
have  chicken  for  dinner.  A chicken  has  no  muscles  in  the  throat,  like 
ours,  to  enable  it  to  swallow  water  as  we  do.  Thus,  it  has  first  to  fill  its 


“Chums." 


beak  with  water,  then  hold  it  up  so  the  water  will  flow  down  the  throat  of 
itself.  As  long  as  the  little  chick  has  its  mother’s  wings  to  sleep  under,  it 
does  not  need  to  put  its  head  under  its  own  wing;  but  when  it  grows  up 
and  spends  the  night  upon  a roost,  it  always  tucks  its  head  under  its  wing 
while  sleeping. 

The  conversation  of  the  barnyard  fowl  covers  many  elemental  emo- 
tions and  is  easily  comprehended.  It  is  well  for  the  children  to  under- 
stand from  the  first  that  the  notes  of  birds  mean  something  definite.  The 
hen  clucks  when  she  is  leading  her  chicks  afield  so  that  they  will  know 
where  she  is  in  the  tall  grass;  the  chicks  follow  “cheeping”  or  “peeping,” 
as  the  children  say,  so  that  she  will  know  where  they  are ; but  if  a chick 


Bird  Study 


43 


feels  itself  lost  its  “peep”  becomes  loud  and  disconsolate;  on  the  other 
hand,  there  is  no  sound  in  the  world  so  full  of  cosy  contentment  as  the  low 
notes  of  the  chick  as  it  cuddles  under  the  mother’s  wing.  When  a hen 
finds  a bit  of  food  she  utters  rapid  notes  which  call  the  chicks  in  a hurry, 
and  when  she  sees  a hawk  she  gives  a warning  “q-r-r”  which  makes  every 
chick  run  for  cover  and  keep  quiet.  When  hens  are  taking  their  sun  and 
dust  baths  together,  they  evidently  gossip  and  we  can  almost  hear  them 
saying,  “Did  you  not  think  Madam  Dorking  made  a great  fuss  over  her  egg 
to-day?”  Or,  “that  overgrown  young  rooster  has  got  a crow  to  match  his 
legs,  has  he  not?”  Contrast  these  low  tones  to  the  song  of  the  hen  as  she 
issues  forth  in  the  first  warm  days  of  spring  and  gives  to  the  world  one  of 
the  most  joyous  songs  of  all  nature.  There  is  quite  a different  quality  in 
the  triumphant  cackle  of  a hen  telling  to  the  world  that  she  has  laid  an 
egg  and  the  cackle  which  comes  from  being  startled.  When  a hen  is 
sitting  or  is  not  allowed  to  sit,  she  is  nervous  and  irritable  and  voices  her 
mental  state  by  scolding.  When  she  is  really  afraid,  she  squalls  and  when 
seized  by  an  enemy,  she  utters  long,  horrible  squawks.  The  rooster 
crows  to  assure  his  flock  that  all  is  well;  he  also  crows  to  show  other 
roosters  what  he  thinks  of  himself  and  of  them.  The  rooster  also  has 
other  notes;  he  will  question  you  as  you  approach  him  and  his  flock,  and 
he  will  give  a warning  note  when  he  sees  a hawk;  when  he  finds  some 
dainty  tidbit  he  calls  his  flock  of  hens  to  him  and  they  usually  arrive  just  in 
time  to  see  him  swallow  the  morsel. 

When  roosters  fight,  they  confront  each  other  with  their  heads  lowered 
and  then  try  to  seize  each  other  by  the  back  of  the  neck  with  their  beaks, 
or  strike  each  other  with  the  wing  spurs,  or  tear  with  the  leg  spurs. 
Weasels,  skunks,  rats,  hawks  and  crows  are  the  most  common  enemies  of 
the  fowls,  and  often  a rooster  will  attack  one  of  these  invaders  and  fight 
valiantly ; the  hen  will  also  fight  if  her  brood  is  disturbed.

LESSON  VII 

Chicken  Ways 

Leading  thought — Chickens  have  interesting  habits  of  life  and  extensive 
conversational  powers. 

Method — For  this  lesson  it  is  necessary  that  the  pupils  observe  the 
inhabitants  of  the  poultry  yard  and  answer  these  questions  a few  at  a 
time. 

Observations — i.  Did  the  chick  get  out  of  the  egg  by  its  own  efforts? 
For  what  use  is  the  little  tooth  which  is  on  the  tip  of  the  upper  part  of  a 
young  chicken’s  beak?  Does  this  remain? 

2.  What  is  the  difference  between  the  down  of  the  chick  and  the 
feathers  of  the  hen  ? The  little  chick  has  wings ; why  can  it  not  fly  ? 

3.  Why  is  the  chick  just  hatched  so  pretty  and  downy,  while  the 
young  robin  is  so  bare  and  ugly?  Why  is  the  young  chick  able  to  see 
while  the  young  robin  is  blind  ? 

4.  How  does  the  young  chick  get  its  food? 

5.  Does  the  chick  chew  its  food  before  swallowing?  If  not,  why? 

6.  How  does  the  chick  drink?  Why  does  it  drink  this  way? 

7.  Where  does  the  chick  sleep  at  night?  Where  will  it  sleep  when 
it  is  grown  up  ? 

8.  Where  does  the  hen  put  her  head  when  she  is  sleeping? 

9.  How  does  the  hen  call  her  chicks  when  she  is  with  them  in  the 
field  ? 

10.  How  does  she  call  them  to  food? 

1 1 . How  does  she  tell  them  that  there  is  a hawk  in  sight  ? 

12.  What  notes  does  the  chick 
make  when  it  is  following  its 
mother  ? When  it  gets  lost  ? 
When  it  cuddles  under  her  wing? 

13.  What  does  the  hen  say 
when  she  has  laid  an  egg?  When 
she  is  frightened?  When  she  is 
disturbed  while  sitting  on  eggs? 
When  she  is  grasped  by  an  enemy? 
How  do  hens  talk  together?  De- 
scribe a hen’s  song. 

14.  When  does  the  rooster 
crow?  What  other  sounds  does 
he  make? 

15.  With  what  weapons  does 
the  rooster  fight  his  rivals  and  his 
enemies  ? 

16.  What  are  the  natural 
enemies  of  the  barnyard  fowls  and 
how  do  they  escape  them?

PIGEONS 

Teacher's  Story 

HERE  is  a mention  of  domesticated  pigeons  by  writers 
three  thousand  years  ago ; and  Pliny  relates  that  the 
Romans  were  fervent  pigeon  fanciers  at  the  beginning 
of  the  Christian  era.  All  of  our  domestic  varieties  of 
pigeons  have  been  developed  from  the  Rock  pigeon,  a 
wild  species  common  in  Europe  and  Asia.  The  carrier 
pigeon  was  probably  the  first  to  be  specially  developed 
because  of  its  usefulness ; its  love  and  devotion  to  mate 
and  young  and  its  homesickness  when  separated  from  them  were  used  by 
man  for  his  own  interests.  When  a knight  of  old  started  off  on  a 
Crusade  or  to  other  wars,  he  took  with  him  several  pigeons  from  the  home 
cote ; and  after  riding  many  days  he  wrote  a letter  and  tied  it  to  the  neck 
or  under  the  wing  of  one  of  his  birds,  which  he  then  set  free,  and  it  flew 
home  with  its  message ; later  he  would  set  free  another  in  like  manner. 
The  drawback  to  this  correspondence  was  that  it  went  only  in  one  direc- 
tion; no  bird  from  home  brought  message  of  cheer  to  the  wandering 
knight.  Now-a-days  mail  routes,  telegraph  wires  and  wireless  currents 
enmesh  our  globe  and  the  pigeon  as  a carrier  is  out-of-date ; but  fanciers 
still  perfect  the  homer  breed  and  train  pigeons  for  very  difficult  flight 
competitions,  some  of  them  a distance  of  hundreds  of  miles.  Recently 
a homer  made  one  thousand  miles  in  two  days,  five  hours  and  fifty 
minutes.  Read  to  the  pupils  “Amaux”  in  Animal  Heroes  by  Thompson 
Seton  to  give  them  an  idea  of  the  life  of  a homing  pigeon.

Handbook  of  Nature-Study 

The  natural  food  of  pigeons  is  grain;  we  feed  them  cracked 
com,  wheat,  peas,  Kafir  corn,  millet  and  occasionally  hemp  seed;  it 

is  best  to  feed  mixed  rations 
as  the  birds  tire  of  the 
monotonous  diet.  Pigeons 
should  be  fed  twice  a day; 
the  pigeon  is  the  only  bird 
which  can  drink  like  a 
horse,  that  is,  with  the 
head  lowered.  The  walk 
of  a pigeon  is  accom- 
panied by  a peculiar  nod- 
ding as  if  the  head  were  in 
some  way  attached  to  the 
feet,  and  this  movement 
sends  waves  of  iridescent 
colors  over  the  bird’s 
plumage.  The  flight  of  the 
pigeon  is  direct  without 
soaring,  the  wings  move 
rapidly  and  steadily,  the 
birds  circling  and  sailing  as 
" Game  Leg ” a homer  pigeon  of  notable  achievement  they  start  or  alight.  The 
(Courtesy  of  Country  Life  in  America.)  CrOW  flaps  hard  and  then 

sails  for  a distance  when 
it  is  inspecting  the  ground,  while  the  hawk  soars  on  motionless 
wings.  It  requires  closer  attention  to  understand  the  language  of  the 
pigeon  than  that  of  the  hen,  nor  has  it  so  wide  a range  of  expression  as 
the  latter ; however,  some  emotions  are  voiced  in  the  cooing,  which  the 
children  will  understand. 

The  nest  is  built  of  grass  and  twigs ; the  mother  pigeon  lays  two  eggs 
fora  sitting;  but  in  some  breeds  a pair  will  raise  from  seven  to  twelve 
broods  per  year.  The  eggs  hatch  in  from  sixteen  to  eighteen  days,  and 
both  parents  share  the  labors  of  incubating.  In  the  case  of  the  homer 
the  father  bird  sits  from  io  a.  m.  to  4 p.  m.  and  the  mother  the  remainder 
of  the  day  and  night.  The  devotion  of  pigeons  to  their  mates  and  to  their 
young  is  great,  and  has  been  sung  by  the  poets  and  praised  by  the  philoso- 
phers during  many  ages ; some  breeds  mate  for  life.  The  young  pigeons 
or  squabs  are  fed  in  a peculiar  manner;  in  the  crops  of  both  parents  is 
secreted  a cheesy  substance,  known  as  pigeon  milk.  The  parent  seizes 
the  beak  of  the  squab  in  its  own  and  pumps  the  food  from  its  own  crop 
into  the  stomach  of  the  young.  This  nutritious  food  is  given  to  the  squab 
for  about  five  days  and  then  replaced  by  grain  which  is  softened  in  the 
parents’  stomachs,  until,  the  squabs  are  old  enough  to  feed  themselves. 
Rats,  mice,  weasels,  and  hawks  are  the  chief  enemies  of  the  pigeons; 
since  pigeons  cannot  fight,  their  only  safety  lies  in  flight. 

As  the  original  Rock  pigeon  built  in  caves,  our  domesticated  varieties 
naturally  build  in  the  houses  we  provide  for  them.  A pigeon  house 
should  not  be  built  for  more  than  fifty  pairs;  it  should  be  well  ventilated 
and  kept  clean ; it  should  face  the  south  or  east  and  be  near  a shallow, 
running  stream  if  possible.  The  nest  boxes  should  be  twelve  inches 
square  and  nine  inches  in  height  with  a door  at  one  side,  so 


Bird  Study 


47 


that  the  nest  may  remain  hidden.  In  front  of  each  door  there 
should  be  a little  shelf  to  act  as  a balcony  on  which  the  resting  parent  bird 
may  sit  and  coo  to 
relieve  the  monotony 
of  the  sitter.  Some 
breeders  make  a 
double  compartment 
instead  of  providing  a 
balcony,  while  in 
Egypt  branches  are 
inserted  in  the  wall 
just  below  the  doors 
of  the  very  ornamen- 
tal pigeon  houses. 

The  houses  should  be 
kept  clean  and  white- 
washed with  lime 
to  which  carbolic  acid 
is  added  in  the  pro- 
portion of  one  tea-  Pouter  pigeons 

spoonful  of  acid  to  two  Photo  hV  j-  Demary 

gallons  of  the  wash;  the  leaf  stems  of  tobacco  should  be  given  to  the 
pigeons  as  material  for  building  their  nests,  so  as  to  help  keep  in  check  the 
bird  lice.  There  should  be  near  the  pigeon  house  plenty  of  fresh  water 
for  drinking  and  bathing;  also  a box  of  table  salt,  and  another  of  cracked 
oyster  shell  and  another  of  charcoal  as  fine  as  ground  coffee.  Salt  is  very 
essential  to  the  health  of  pigeons.  The  house  should  be  high  enough  from 
the  ground  to  keep  the  inmates  safe  from  rats  and  weasels. 

LESSON  VIII 
Pigeons 

Leading  thought — The  pigeons  differ  in  appearance  from  other  birds 
and  also  in  their  actions.  Their  nesting  habits  are  very  interesting  and 
there  are  many  things  that  may  be  done  to  make  the  pigeons  comfortable. 
They  were,  in  ancient  days,  used  as  letter  carriers. 

Methods — If  there  are  pigeons  kept  in  the  neighborhood,  it  is  best  to 
encourage  the  pupils  to  observe  these  birds  out-of-doors.  Begin  the 
work  with  an  interesting  story  and  with  a few  questions  which  will  arouse 
the  pupils’  interest  in  the  birds.  A pigeon  in  a cage  in  the  schoolroom  for 
a special  lesson  on  the  bird’s  appearance,  is  desirable  but  not  necessary. 

Observations — % For  an  out-of-door  exercise  during  recess  let  the 
pupils  observe  the  pigeon  and  tell  the  colors  of  the  beak,  eyes,  top  of  the 
head,  back,  breast,  wings,  tail,  feet  and  claws.  This  exercise  is  excellent 
training  to  fit  the  pupils  to  note  quickly  the  colors  of  the  wild  birds. 

2.  On  what  do  pigeons  feed?  Are  they  fond  of  salt? 

3.  Describe  how  a pigeon  drinks.  How  does  it  differ  in  this  respect 
from  other  birds? 

4'.  Describe  the  peculiar  movement  of  the  pigeon  when  walking. 

5.  Describe  the  pigeon’s  flight.  Is  it  rapid,  high  in  the  air,  do  the 
wings  flap  constantly,  etc?  What  is  the  chief  difference  between  the 
flight  of  pigeons,  crows  or  hawks  ? 


48  Handbook  of  Nature-Study 

6.  Listen  to  the  cooing  of  a pigeon  and  see  if  you  can  understand 
the  different  notes. 

7.  Describe  the  pigeon’s  nest.  How  many  eggs  are  laid  at  a time  ? 

8.  Describe  how  the  parents  share  the  labors  in  hatching  the  eggs, 
and  how  long  after  the  eggs  are  laid  before  the  young  hatch  ? 

9.  How  do  the  parents  feed  their  young  and  on  what  material? 

10.  What  are  the  enemies  of  pigeons  and  how  do  they  escape  from 
them?  How  can  we  protect  them? 

11.  Describe  how  a pigeon  house  should  be  built. 

12.  What  must  you  do  for  pigeons  to  keep  them  healthy  and  com- 
fortable ? 

13.  How  many  breeds  of  pigeons  do  you  know?  Describe  them.

For  my  own  part  I readily  concur  with  you  in  supposing  that  housedoves  are 
derived  from  the  small  blue  rock-pigeon,  Columba  livia , for  many  reasons.  * * * 

But  what  is  worth  a hundred  arguments  is,  the  instance  you  give  in  Sir  Roger  Mostyn’s 
housedoves  in  Caernarvonshire ; which,  though  tempted  by  plenty  of  food  and  gentle 
treatment,  can  never  be  prevailed  on  to  inhabit  their  cote  for  any  time;  but  as  soon  as  they 
begin  to  breed,  betake  themselves  to  the  fastnesses  of  Ormshead,  and  deposit  their  young 
in  safety  amidst  the  inaccessible  caverns  and  precipices  of  that  stupendous  promontory. 
“You  may  drive  nature  out  with  a pitchfork,  but  she  will  always  return :” 

“Naturam  expellas  furca  * * * tamen  usque  recurret.” 

Virgil,  as  a familiar  occurrence,  by  way  of  simile,  describes  a dove  haunting  the 
cavern  of  a rock  in  such  engaging  numbers,  that  I cannot  refrain  from  quoting  the 
passage. 

“ Qualis  spelunca  subito  commota  Columba, 

Cui  domus,  et  dulces  latebroso  in  pumice  nidi, 

Fertul  in  arva  volans,  plausumque  exterrita  pennis 
Dat  tecto  ingentem,  mox  aere  lapsa  quieto, 

Radit  iter  liquidum,  celeres  neque  commovet  alas." 

(Virg.  Aen.  v.  2 13-2 17). 

“As  when  a dove  her  rocky  hold  forsakes, 

Roused,  in  a fright  her  sounding  wings  she  shakes; 

The  cavern  rings  with  clattering: — out  she  flies. 

And  leaves  her  callow  care,  and  cleaves  the  skies; 

At  first  she  flutters: — but  at  length  she  springs 
To  smoother  flight,  and  shoots  upon  her  wings.”

THE  CANARY  AND  THE  GOLDFINCH 

Teacher's  Story 

N childhood  the  language  of  bird's  and  animals  is  learned 
unconsciously.  What  child,  who  cares  for  a canary,  does 
not  understand  its  notes  which  mean  loneliness,  hunger, 
eagerness,  joy,  scolding,  fright,  love  and  song! 

The  pair  of  canaries  found  in  most  cages  are  not  natural 
mates.  The  union  is  one  de  convenance,  forced  upon  them 
by  people  who  know  little  of  bird  affinities.  We  could 
hardly  expect  that  such  a mating  would  be  always  happy. 
The  singer,  as  the  male  is  called,  is  usually  arbitrary  and  tyrannical  and 
does  not  hesitate  to  lay  chastising  beak  upon  his  spouse.  The  expression 
of  affection  of  the  two  is  usually  very  practical,  consisting  of  feeding  each 
other  with  many  beguiling  notes  and  much  fluttering  of  wings.  The 
singer  may  have  several  songs ; whether  he  has  many  or  few  depends  upon 
his  education ; he  usually  shows  exultation  when  singing  by  throwing  the 
head  back  like  a prima-donna,  to  let  the  music  well  forth.  He  is  usually 
brighter  yellow  in  color  with  more  brilliantly  black  markings  than  his 
mate;  she  usually  has  much  gray  in  her  plumage.  But  there  are  about 
fifty  varieties  of  canaries  and  each  has  distinct  color  and  markings. 

Canaries  should  be  given  a more  varied  diet  than  most  people  think. 
The  seeds  we  buy  or  that  we  gather  from  the  plantain  or  wild  grasses,  they 
eat  eagerly.  They  like  fresh,  green  leaves  of  lettuce  and  chickweed  and 
other  tender  herbage;  they  enjoy  bread  and  milk  occasionally.  There 
should  always  be  a piece  of  cuttle-fish  bone  or  sand  and  gravel  where  they 
can  get  it,  as  they  need  grit  for  digestion.  Above  all,  they  should  have 
fresh  water.  Hard-boiled  egg  is  given  them  while  nesting.  The  canary 
seed  which  we  buy  for  them  is  the  product  of  a grass  in  the  Canary  Islands. 
Hemp  and  rape  seed  are  also  sold  for  canary  food. 

The  canary’s  beak  is  wide  and  sharp  and  fitted  for  shelling  seeds;  it  is 
not  a beak  fitted  for  capturing  insects.  The  canary,  when  drinking,  does 
not  have  to  lift  the  beak  so  high  in  the  air  in  order  to  swallow  the  water  as 
do  some  birds.  The  nostrils  are  in  the  beak  and  are  easily  seen;  the  ear 
is  hidden  by  the  feathers.  The  canary  is  a fascinating  little  creature 
when  it  shows  interest  in  an  object;  it  has  such  a knowing  look,  and  its 
perfectly  round,  black  eyes  are  so  intelligent  and  cunning.  If  the  canary 
winks,  the  act  is  so  rapid  as  to  be  seen  with  difficulty,  but  when  drowsy, 
the  little  inner  lid  appears  at  the  inner  corner  of  its  eye  and  the  outer  lids 
close  so  that  we  may  be  sure  that  they  are  there;  the  lower  lid  covers 
more  of  the  eye  than  the  upper. 

The  legs  and  toes  are  covered  with  scale  armor;  the  toes  have  long, 
curved  claws  that  are  neither  strong  nor  sharp  but  are  especially  fitted  for 
holding  to  the  perch ; the  long-hind  toe  with  its  stronger  claw  makes  com- 
plete the  grasp  on  the  twig.  When  the  canary  is  hopping  about  on  the 
bottom  of  the  cage  we  can  see  that  its  toes  are  more  fitted  for  holding  to 
the  perch  than  for  walking. 

When  the  canary  bathes,  it  ducks  its  head  and  makes  a great  splashing 
with  its  wings  and  likes  to  get  thoroughly  wet.  Afterward,  it  sits  all 
bedraggled  and  “humped  up”  for  a time  and  then  usually  preens  its 
feathers  as  they  dry.  When  going  to  sleep,  it  at  first  fluffs  out  its  feathers 
and  squats  on  the  perch,  draws  back  its  head  and  looks  very  drowsy. 


50 


Handbook  of  Nature-Study 


Later  it  tucks  its  head  under  its  wing  for  the  night  and  then  looks  like  a 
little  ball  of  feathers  on  the  perch. 

Canaries  make  a great  fuss  when  building  their  nest.  A pasteboard 
box  is  usually  given  them  with  cotton  and  string  for  lining;,  usually  one 
pulls  out  what  the  other  puts  in;  and  they  both  industriously  tear  the 
paper  from  the  bottom  of  the  cage  to  add  to  their  building  material. 
Finally,  a make-shift  of  a nest  is  completed  and  the  eggs  are  laid.  If  the 
singer  is  a good  husband,  he  helps  incubate  the  eggs  and  feeds  his  mate 
and  sings  to  her  frequently ; but  often  he  is  quite  the  reverse  and  abuses 
her  abominably.  The  nest  of  the  caged  bird  is  very  different  in  appear- 
ance from  the  neat  nests  of  grass,  plant  down,  and  moss  which  the  wild 
ancestors  of  these  birds  made  in  some  safe  retreat  in  the  shrubs  or  ever- 
greens of  the  Canary  Islands.  The  canary  eggs  are  pale  blue,  marked 
with  reddish-brown.  The  incubation  period  is  13  to  14  days.  The 
young  are  as  scrawny  and  ugly  as  most  little  birds  and  are  fed  upon  food 
partially  digested  in  the  parents’  stomachs.  Their  first  plumage  resem- 
bles that  of  the  mother  usually. 

In  their  wild  state  in  the  Canary  and  Azore  Islands,  the  canaries  are 
olive  green  above  with  golden  yellow  breasts.  When  the  heat  of  spring 
begins,  they  move  up  the  mountains  to  cooler  levels  and  come  down  again 
in  the  winter.  They  may  rear  three  or  four  broods  on  their  way  up  the 
mountains,  stopping  at  successive  heights  as  the  season  advances,  until 
finally  they  reach  the  high  peaks. 


THE  GOLDFINCH  OR  THISTLE  BIRD 


A pair  of  goldfinches. 
(Courtesy  of  Audubon  Educational 
Leaflet  No.  17). 


The  goldfinches  are  bird  midgets 
but  their  songs  are  so  sweet  and 
reedy  that  they  seem  to  fill  the 
world  with  music  more  effectually 
than  many  larger  birds.  They 
are  fond  of  the  seeds  of  wild 
grass,  and  especially  so  of  thistle 
seed ; and  they  throng  the  pastures 
and  fence  corners  where  the  thistles 
hold  sway.  In  summer,  the  male 
has  bright  yellow  plumage  with 
a little  "black  cap  “pulled  down 
over  his  nose”  like  that  of  a 
grenadier.  He  has  also  a black 
tail  and  wings  with  white-tipped 
coverts  and  primaries.  The  tail 
feathers  have  white  on  their  inner 
webs  also,  which  does  not  show 
when  the  tail  is  closed.  The  female 
has  the  head  and  back  Drown  and 
the  under  parts  yellowish  white, 
with  wings  and  tail  resembling 
those  of  the  male  except  that  they 
are  not  so  vividly  black.  In 
winter  the  male  dons  a dress  more 
like  that  of  his  mate ; he  loses  his 


black  cap  but  keeps  his  black  wings  and  tail.

The  song  of  the  goldfinch  is  exquisite  and  he  sings  during  the  entire 
period  of  his_  golden  dress ; he  sings  while  flying  as  well  as  when  at  rest. 
The  flight  is  in  itself  beautiful,  being  wave-like  up  and  down,  in  graceful 
curves.  Mr.  Chapman  says  when  on  the  down  half  of  the  curve  the  male 
sings  “Per-chick  or-ree.”  The  goldfinch's  call  notes  and  alarm  notes  are 
very  much  like  those  of  the  canary. 

Since  the  goldfinches  live  so  largely  upon  seeds  of  grasses,  they  stay 
with  us  in  small  numbers  during  the  winter.  During  this  period  both 
parents  and  young  are  dressed  in  olive  green,  and  their  sweet  call  notes 
are  a surprise  to  us  of  a cold,  snowy  morning,  for  they  are  associated  in  our 
memory  with  summer.  The  male  dons  his  winter  suit  in  October. 

The  goldfinch  nest  is  a mass  of  fluffiness.  These  are  the  only  birds 
that  make  feather  beds  for  their  young.  But,  perhaps,  we  should  say 
beds  of  down,  since  it  is  the  thistle  down  which  is  used  for  this  mattress. 
The  outside  of  the  nest  consists  of  fine  shreds  of  bark  or  fine  grass  closely 
woven ; but  the  inner  portion  is  a mat  of  thistle  down — an  inch  and  a half 
thick  of  cushion  for  a nest  which  has  an  opening  of  scarcely  three  inches; 
sometimes  the  outside  is  ornamented  with  lichens.  The  nest  is  usually 
placed  in  some  bush  or  tree,  often  in  an  evergreen,  and  not  more  than  5 or 
6 feet  from  the  ground;  but  sometimes  it  is  placed  30  feet  high.  The 
eggs  are  from  four  to  six  in  number  and  bluish  white  in  color.  The  female 
builds  the  nest,  her  mate  cheering  her  with  song  meanwhile;  he  feeds  her 
while  she  is  incubating  and  helps  feed  the  young.  A strange  thing  about 
the  nesting  habits  of  the  goldfinches  is  that  the  nest  is  not  built  until 
August.  It  has  been  surmised  that  this  nesting  season  is  delayed  until 
there  is  an  abundance  of  thistle  down  for  building  material.  Audubon 
Leaflet  No.  17  gives  special  information  about  these  birds  and  also 
furnishes  an  outline  of  the  birds  for  the  pupils  to  color. 


LESSON  IX 


The  Canary  and  the  Goldfinch 


Leading  thought — The  canary  is  a very  close  relative  of  the  common 
wild  goldfinch.  If  we  compare  the  habits  of  the  two  we  can  understand 
how  a canary  might  live  if  it  were  free. 

Method — Bring  a canary  to  the  schoolroom  and  ask  for  observations. 
Request  the  pupils  to  compare  the  canary  with  the  goldfinches  which  are 
common  in  the  summer.  The  canary  offers  opportunity  for  very  close 
observation  which  will  prove  excellent  training  for  the  pupils  for  beginning 
bird  study. 

Observations — 1.  If  there  are  two  canaries  in  the  cage  are  they 
always  pleasant  to  each  other?  Which  one  is  the  “boss?”  How  do  they 
show  displeasure  or  bad  temper?  How  do  they  show  affection  for  each 
other? 


2.  Which  one  is  the  singer?  Does  the  other  one  ever  attempt  to 
sing?  What  other  notes  do  the  canaries  make  besides  singing?  How  do 
they  greet  you  when  you  bring  their  food?  What  do  they  say  when  they 
are  lonesome  and  hungry  ? 

3.  Does  the  singer  have  more  than  one  song?  How  does  he  act 
while  singing?  Why  does  he  throw  back  his  head  like  an  opera  singer 
when  singing  ?

4.  Are  the  canaries  all  the  same  color?  What  is  the  difference  in 

color  between  the  singer  and  the  mother  bird?  Describe  the  colors  of 
each  in  your  note  book  as  follows:  Top  and  sides  of  head,  back,  tail, 

wings,  throat,  breast  and  under  parts? 

5.  What  does  the  canary  eat?  What  sort  of  seeds  do  we  buy  for  it? 
What  seeds  do  we  gather  for  it  in  our  garden  ? Do  the  goldfinches  live  on 
the  same  seeds?  What  does  the  canary  do  to  the  seeds  before  eating 
them  ? What  tools  does  he  use  to  take  off  the  shells  ? 

6.  Notice  the  shape  of  the  canary’s  beak.  Is  it  long  and  strong  like 
a robin’s?  Is  it  wide  and  sharp  so  that  it  can  shell  seeds?  If  you  should 
put  an  insect  in  the  cage  would  the  canary  eat  it  ? 

7.  Why  do  we  give  the  canary  cuttlebone?  Note  how  it  takes  off 
pieces  of  the  bone.  Could  it  do  this  if  its  beak  were  not  sharp? 

8.  Note  the  actions  of  the  birds  when  they  drink.  Why  do  they  do 
this? 

9.  Can  you  see  the  nostrils?  Where  are  they  situated?  Why  can 
you  not  see  the  ear? 

10.  When  the  canary  is  interested  in  looking  at  a thing  how  does  it 
act?  Look  closely  at  its  eyes?  Does  it  wink?  How  does  it  close  its 
eyes?  When  it  is  drowsy  can  you  see  the  little  inner  lid  come  from  the 
comer  of  the  eye  nearest  the  beak?  Is  this  the  only  lid? 

11.  How  are  the  legs  and  feet  covered?  Describe  the  toes.  Com- 
pare the  length  of  the  claw  with  the  length  of  the  toe.  What  is  the  shape 
of  the  claw?  Do  you  think  that  such  shaped  claws  and  feet  are  better 
fitted  for  holding  to  a branch  than  for  walking?  Note  the  arrangement 
of  the  toes  when  the  bird  is  on  its  perch.  Is  the  hind  toe  longer  and 
stronger?  If  so,  why?  Do  the  canaries  hop  or  walk  about  the  bottom 
of  the  cage  ? 

1 2 . What  is  the  attitude  of  the  canary  when  it  goes  to  sleep  at  night  ? 
How  does  it  act  when  it  takes  a bath?  How  does  it  get  the  water  over  its 
head?  Over  its  back?  What  does  it  do  after  the  bath ? If  we  forget  to 
put  in  the  bath  dish  how  does  the  bird  get  its  bath  ? 

NESTING  HABITS  TO  BE  OBSERVED  IN  THE  SPRING 

13.  When  the  canaries  are  ready  to  build  a nest  what  material  do 
we  furnish  them  for  it?  Does  the  father  bird  help  the  mother  to  build 
the  nest?  Do  they  strip  off  the  paper  on  the  bottom  of  the  cage  for  nest 
material?  Describe  the  nest  when  it  is  finished. 

14.  Describe  the  eggs  ‘carefully.  Does  the  father  bird  assist  in 
sitting  on  the  eggs?  Does  he  feed  the  mother  bird  when  she  is  sitting? 

15.  How  long  after  the  eggs  are  laid  before  the  young  ones  hatch? 
Do  both  parents  feed  the  young?  Do  they  swallow  the  food  first  and 
partially  digest  it  before  giving  it  to  the  young? 

16.  How  do  the  very  young  birds  look?  What  is  their  appearance 
when  they  leave  the  nest?  Does  the  color  of  their  plumage  resemble 
that  of  the  father  or  the  mother? 

17.  Where  did  the  canaries  originally  come  from?  Find  the  place 
on  the  map.

The  Goldfinch 

Leading  thought — Goldfinches  are  seen  at  their  best  in  late  summer  or 
September  when  they  appear  in  flocks  wherever  the  thistle  seeds  are 
found  in  abundance.  Goldfinches  so  resemble  the  canaries  in  form,  color, 
song  and  habits  that  they  are  called  wild  canaries. 

Method — The  questions  for  this  lesson  should  be  given  to  the  pupils 
before  the  end  of  school  in  June.  The  answers  to  the  questions  should  be 
put  in  their  field  note-books  and  the  results  be  reported  to  the  teacher  in 
class  when  the  school  begins  in  the  autumn. 

Observations — i.  Where  do  you  find  the  goldfinches  feeding?  How 
can  you  distinguish  the  father  from  the  mother  birds  and  from  the  young 
ones  in  color  ? 

2.  Describe  the  colors  of  the  male  goldfinch  and  also  of  the  female  as 

follows : Crown,  back  of  head,  back,  tail,  wings,  throat,  breast  and  lower 

parts.  Describe  in  particular  the  black  cap  of  the  male. 

3.  Do  you  know  the  song  of  the  goldfinch?  Is  it  like  the  song  of  the 
canary?  What  other  notes  has  the  goldfinch? 

4.  Describe  the  peculiar  flight  of  the  goldfinches.  Do  they  fly  high 
in  the  air?  Do  you  see  them  singly  or  in  flocks  usually? 

5.  Where  do  the  goldfinches  stay  during  the  winter?  What  change 
takes  place  in  the  coat  of  the  male  during  the  winter?  Why?  What  do 
they  live  upon  during  the  winter? 

6.  At  what  time  of  year  do  the  goldfinches  build  their  nests?  Why 
do  they  build  these  so  much  later  than  other  birds?  Describe  the  nest. 
Where  is  it  placed?  How  far  above  the  ground ? How  far  from  a stream 
or  other  water?  Of  what  is  the  outside  made?  The  lining?  What  is 
the  general  appearance  of  the  nest?  Do  you  think  the  goldfinches  wait 
until  the  thistles  are  ripe  in  order  to  gather  plenty  of  food  for  their  young, 
or  to  get  the  thistle  down  for  their  nests  ? What  is  the  color  of  the  eggs  ?

Sometimes  goldfinches  one  by  one  will  drop 
From  low-hung  branches;  little  space  they  stop, 
But  sip,  and  twitter,  and  their  feathers  sleek, 

Then  off  at  once,  as  in  a wanton  freak; 

Or  perhaps,  to  show  their  black  and  golden  wings; 
Pausing  upon  their  yellow  flutterings.

THE  ROBIN 

Teacher's  Story 

OST  of  us  think  we  know  the  robin  well,  but  very  few 
U of  us  know  definitely  the  habits  of  this,  our  commonest 
Wf  bird.  The  object  of  this  lesson  is  to  form  in  the  pupils 
W~  a habit  of  careful  observation,  and  enable  them  to  read 
for  themselves  the  interesting  story  of  this  little  life 
which  is  lived  every  year  before  their  eyes.  Moreover, 
a robin  note-book,  if  well  kept,  is  a treasure  for  any  child;  and  the  close 
observation  necessary  for  this  lesson  trains  the  pupils  to  note  in  a com- 
prehending way  the  habits  of  other  birds.  It  is  the  very  best  preparation 
for  bird  study  of  the  right  sort. 

A few  robins  occasionally  find  a swamp  where  they  can  obtain  food  to 
nourish  them  during  the  northern  winter,  but  for  the  most  part,  they  go 
in  flocks  to  our  Southern  States  where  they  settle  in  swamps  and  cedar 
forests  and  live  upon  berries.  They  are  killed  in  great  numbers  by  the 
native  hunters  who  eat  them  or  sell  them  for  table  use,  a performance  not 
understandable  to  the  northerner.  The  robins  do  not  nest  nor  sing  while 
in  Southland,  and  no  wonder!  When  the  robins  first  come  to  us  in  the 
spring  they  feed  on  wild  berries,  being  especially  fond  of  those  of  the 
Virginia  creeper.  As  soon  as  the  frost  is  out  of  the  ground  they  begin 
feeding  on  earthworms,  cutworms,  white  grubs,  and  other  insects.  The 
male  robins  come  first,  but  do  not  sing  until  their  mates  arrive. 

The  robin  is  ten  inches  long  and  the  English  sparrow  is  only  six  and 
one-third  inches  long;  the  pupils  should  get  the  sizes  of  these  two  birds 
fixed  in  their  minds  for  comparison  in  measuring  other  birds.  The  father 
robin  is  much  more  decided  in  color  than  his  mate;  his  beak  is  yellow, 
there  is  a yellow  ring  about  the  eye  and  a white  spot  above  it.  The  head 
is  black  and  the  back  slaty-brown ; the  breast  is  brilliant  reddish  brown 
or  bay  and  the  throat  is  white,  streaked  with  black.  The  mother  bird  has 
paler  back  and  breast  and  has  no  black  upon  the  head.  The  wings  of  both 
are  a little  darker  than  the  back,  the  tail  is  black  with  the  two  outer 
feathers  tipped  with  white.  These  white  spots  do  not  show  except  when 
the  bird  is  flying  and  are  “call  colors,”  that  is,  they  enable  the  birds  to 
see  each  other  and  thus  keep  together  when  flying  in  flocks  during  the 
night.  The  white  patch  made  by  the  under  tail-coverts  serves  a similar 
purpose.  The  feet  and  legs  are  strong  and  dark  in  color. 

The  robin  has  many  sweet  songs  and  he  may  be  heard  in  the  earliest 
dawn  and  also  in  the  evenings;  if  he  wishes  to  cheer  his  mate  he  may 
burst  into  song  at  any  time.  He  feels  especially  songful  before  the 
summer  showers  when  he  seems  to  sing,  “I  have  a theory,  a theory,  its 
going  to  rain.”  And  he  might  well  say  that  he  also  has  a theory,  based 
on  experience,  that  a soaking  shower  will  drive  many  of  the  worms  and 
larvae  in  the  soil  up  to  the  surface  where  he  can  get  them.  Besides  these 
songs  the  robins  have  a great  variety  of  notes  which  the  female  shares, 
although  she  is  not  a singer.  The  agonizing,  angry  cries  they  utter  when 
they  see  a cat  or  squirrel  must  express  their  feelings  fully;  while  they  give 
a very  different  warning  note  when  they  see  crow  or  hawk,  a note  hard  to 
describe,  but  which  is  a long,  not  very  loud  squeak. 

A robin  can  run  or  hop  as  pleases  him  best,  and  it  is  interesting  to  see 
one,  while  hunting  earthworms  run  a little  distance,  then  stop  to  bend  the 


Bird  Study 


55 


head  and  listen  for  his  prey,  and  when  he  finally  seizes  the  earthworm  he 
braces  himself  on  his  strong  legs  and  tugs  manfully  until  he  sometimes 
almost  falls  over  backward  as  the  worm  lets  go  its  hold.  The  robins, 
especially  at  nesting  time,  eat  many  insects  as  well  as  earthworms. 

The  beginning  of  a robin’s  nest  is  very  interesting;  much  strong  grass, 
fine  straw,  leaves  and  rootlets  are  brought  and  placed  on  a secure  support. 
When  enough  of  this  material  is  collected  and  arranged,  the  bird  goes  to 
the  nearest  mud  puddle  or  stream  margin  and  fills  its  beak  with  soft 
mud  and  going  back  “peppers”  it  into  the  nest  material,  and  after  the 
latter  is  soaked  the  bird  gets  into  it  and  molds  it  to  the  body  by  nestling 
and  turning  around  and  around.  In  one  case  which  the  author  watched 
the  mother  bird  did  this  part  of  the  building,  although  the  father  worked 
industriously  in  bringing  the  other  materials.  After  the  nest  is  molded 
but  not  yet  hardened,  it  is  lined  with  fine  grass  or  rootlets.  If  the  season 
is  very  dry  and  there  is  no  soft  mud  at  hand,  the  robins  can  build  without 
the  aid  of  this  plaster.  There  are  usually  four  eggs  laid  which  are  ex- 
quisite greenish  blue  in  color. 

Both  parents  share  the  monotonous  business  of  incubating,  and  in  the 
instance  under  the  eyes  of  the  author  the  mother  bird  was  on  the  nest  at 
night;  the  period  of  incubating  is  from  eleven  to  fourteen  days.  The 
most  noticeable  thing  about  a very  young  robin  is  its  wide,  yellow- 
margined  mouth,  which  it  opens  like  a satchel  every  time  the  nest  is 
jarred.  This  wide  mouth  cannot  but  suggest  to  anyone  that  it  is  meant 


Robin  on  nest. 


56 


Handbook  of  Nature-Study 


to  be  stuffed,  and  the  two  parents  work  very  hard  to  fill  it.  Both  parents 
feed  the  young  and  often  the  father  feeds  the  mother  bird  while  she  is 
brooding.  Professor  Treadwell  experimented  with  young  robins  and 
found  that  each  would  take  68  earthworms  daily;  these  worms  if  laid 
end  to  end  would  measure  about  14  feet.  Think  of  14  feet  of  earthworm 
being  wound  into  the  little  being  in  the  nest,  no  wonder  that  it  grows  so 
fast!  I am  convinced  that  each  pair  of  robins  about  our  house  has  its 
own  special  territory  for  hunting  worms,  and  that  any  trespasser  is 
quickly  driven  off.  The  young  bird’s  eyes  are  unsealed  when  they  are 
from  six  to  eight  days  old,  and  by  that  time  the  feather  tracts,  that  is, 
the  place  where  the  feathers  are  to  grow,  are  covered  by  the  spine-like 
pin-feathers ; these  feathers  push  the  down  out  and  it  often  clings  to  their 
tips.  In  eleven  days  the  birds  are  pretty  well  feathered;  their  wing 
feathers  are  fairly  developed  but  alas,  they  have  no  tail  feathers!  When 
a young  robin  flies  from  the  nest  he  is  a very  uncertain  and  tippy  young- 
ster not  having  any  tail  to  steer  him  while  flying,  nor  to  balance  him  when 
alighting. 

It  is  an  anxious  time  for  the  old  robins  when  the  young  ones  leave  the 
nest,  and  they  flutter  about  and  scold  at  any  one  who  comes  in  sight,  so 
afraid  are  they  that  injury  will  come  to  their  inexperienced  young  ones; 
for  some  time  the  parents  care  for  the  fledglings,  solicitously  feeding  them 
and  giving  them  warnings  of  danger.  The  young  robin  shows  in  its 
plumage  its  relation  to  the  thrush  family,  for  it  is  yellowish  and  very 
spotted  and  speckled,  especially  the  breast.  The  parents  may  raise 
several  broods,  but  they  never  use  the  same  nest  for  two  consecutive 
broods,  both  because  it  may  be  infested  with  parasites  and  because  it  is 
more  or  less  soiled;  although  the  mother  robin  works  hard  to  keep  it 
clean,  carrying  away  all  waste  matter  in  her  beak  and  dropping  it. 
Robins  do  not  sing  much  after  the  breeding  season  is  over  until  after  they 
have  molted.  They  are  fond  of  cherries  and  other  pulp  fruits  and  often 
do  much  damage  to  such  crops.  The  wise  orchardist  will  plant  a few 
Russian  mulberry  trees  at  a reasonable  distance  from  his  cherry  trees, 
and  thus,  by  giving  the  robins  a fruit  which  they  like  better,  and  which 
ripens  a little  earlier,  he  may  save  his  cherries.  It  has  been  proven  con- 
clusively that  the  robins  are  far  more  beneficial  than  damaging  to  the 
farmer;  they  destroy  many  noxious  insects,  two-thirds  of  their  food  the 
entire  year  consisting  of  insects;  during  April  and  May  they  do  a great 
work  in  destroying  cutworms. 

The  robins  stay  with  us  later  than  most  migrating  birds,  not  leaving 
us  entirely  before  November.  Their  chief  enemies  in  northern  climates 
are  cats,  crows  and  squirrels.  Cats  should  be  taught  to  let  birds  alone 
(see  lesson  on  cat)  or  should  be  killed.  The  crows  have  driven  the  robins 
into  villages  where  they  can  build  their  nests  under  the  protection  of 
man.  If  crows  venture  near  a house  to  attack  the  robins,  firing  a gun  at 
them  once  or  twice  will  give  them  a hint  which  they  are  not  slow  to  take. 
The  robins  of  an  entire  neighborhood  will  attack  a nest-robbing  crow,  but 
usually  too  late  to  save  the  nestlings.  The  robins  can  defend  themselves 
fairly  well  against  the  red  squirrel  unless  he  steals  the  contents  of  the  nest 
while  the  owners  are  away.  There  can  be  no  doubt  that  the  same  pair  of 
robins  return  to  the  same  nesting  place  year  after  year.  On  the  Cornell 
Campus  a robin  lacking  the  white  tip  on  one  side  of  his  tail  was  noted 
to  have  returned  fo  the  same  particular  feeding  ground  for  several  years; 


Bird  Study 


57 


and  we  are  very  certain  that  the  same  female  bird  built  in  the  vines  of  our 
piazza  for  seven  consecutive  years;  it  took  two  years  to  win  her  confi- 
dence; but  after  that,  she  seemed  to  feel  as  if  she  were  a part  of  the  family 
and  regarded  us  all  as  friends.  We  were  sure  that  during  her  fifth  year 
she  brought  a new  young  husband  to  the  old  nesting  site ; probably  her 
faithful  old  husband  had  been  served  for  a dinner  in  some  Tennessee  hotel 
during  the  previous  winter.

LESSON  X 
The  Robin 

Leading  thought — To  understand  all  we  can  about  the  life  and  ways  of 
the  robin. 

Methods — For  first  and  second  grades  this  work  may  be  done  by 
means  of  an  extra  blackboard,  or  what  is  far  better,  sheets  of  ordinary, 
buff,  manilla  wrapping  paper  fastened  together  at  the  upper  end,  so  that 
they  may  be  hung  and  turned  over  like  a calendar.  On  the  outside  page 
make  a picture  of  a robin  in  colored  chalk  or  crayons,  coloring  according 
to  the  children’s  answers  to  questions  of  series  “6”.  Devote  each  page 
to  one  series  of  questions,  as  given  below.  Do  not  show  these  questions

For  third  or  higher  grades  the  pupils  should  have  individual  note- 
books in  which  each  one  may  write  his  own  answers  to  the  questions  of  the 
successive  series,  which  should  be  written  on  the  blackboard  at  proper 
time  for  the  observations.  This  note-book  should  have  a page  about  6x8 
inches  and  may  be  made  of  any  blank  paper.  The  cover  or  first  page 
should  show  the  picture  of  the  robin  colored  by  the  pupil,  and  may  con- 
tain other  illustrative  drawings,  and  any  poems  or  other  literature 
pertinent  to  the  subject.  If  prizes  are  awarded  in  the  school,  a bird  book 
should  be  given  as  award  for  the  best  note-book  in  the  class.

THE  BLUEBIRD 

Teacher's  Story 

TERN  as  were  our  Pilgrim  Fathers,  they  could  not  fail 
to  welcome  certain  birds  with  plumage  the  color  of  June 
skies,  whose  sweet  voices  brought  hope  and  cheer  to 
their  homesick  hearts  at  the  close  of  that  first,  long, 
hard  winter  of  1621.  The  red  breasts  of  these  birds 
brought  to  memory  the  robins  of  old  England  and  so 
they  were  called  “Blue  robins”;  and  this  name  ex- 
presses well  the  relationship  implied,  because  the  blue- 
birds and  robins  of  America  are  both  members  of  the 
thrush  family,  a family  noted  for  exquisite  song. 

The  bluebirds  are  usually  ahead  of  the  robins  in  the  northward  journey 
and  arrive  in  New  York  often  amid  the  blizzards  of  early  March,  their 
soft,  rich  “curly”  notes  bringing,  even  to  the  doubting  mind,  glad  con- 
victions of  coming  spring.  There  is  a family  resemblance  between  voices 
of  bluebird  and  robin,  a certain  rich  quality  of  tone,  but  the  robin’s  song 
is  far  more  assertive  and  complex  than  is  the  soft,  “purling”  song  of  the 
bluebird,  which  has  been  vocalized  as  “tru-al-ly,  tru-al-ly.”  These  love 
songs  cease  with  the  hard  work  of  feeding  the  nestlings  in  April,  but  may 
be  heard  again  as  a prelude  to  the  second  brood  in  June.  The  red  breast 
of  the  bluebird  is  its  only  color  resemblance  to  the  robin,  although  the 
young  bluebirds  and  robins  are  both  spotted,  showing  the  thrush  colors. 
The  robin  is  so  much  larger  than  the  bluebird  that  commonly  the  relation- 
ship is  not  noticed.  This  is  easily  explained  because  there  is  nothing  to 
suggest  a robin  in  the  exquisite  cerulean  blue  of  the  bluebird’s  head,  back, 
tail  and  wings.  This  color  is  most  brilliant  when  the  bird  is  on  the  wing, 
in  the  sunshine.  However,  there  is  a certain  mirror-like  quality  in  these 
blue  feathers;  and  among  leaf  shadows  or  even  among  bare  branches  they 
in  a measure,  reflect  the  surroundings  and  render  the  bird  less  noticeable. 
The  female  is  paler,  being  grayish  blue  above  and  with  only  a tinge  of  red- 
brown  on  the  breast;  both  birds  are  white  beneath. 

The  bluebirds  haunt  open  woods,  fields  of  second  growth  and  especially 
old  orchards.  They  flit  about  in  companies  of  three  or  four  until  they 
mate  for  nesting.  While  feeding,  the  bluebird  usually  sits  on  a low 
branch  keeping  a keen  eye  on  the  ground  below,  now  and  then  dropping 
suddenly  on  an  unsuspecting  insect  and  then  returning  to  its  perch;  it 
does  not  remain  on  the  ground  hunting  food  as  does  the  robin.  The  nest 
is  usually  built  in  a hole  in  a tree  or  post  and  is  made  of  soft  grass.  A 
hollow  apple  tree  is  a favorite  nesting  site. 

In  building  birdhouses  we  should  bear  in  mind  that  a cavity  about  ten 
inches  deep  and  six  inches  in  height  and  width  will  give  a pair  of  bluebirds 
room  for  building  a nest.  The  opening  should  not  be  more  than  two  or 
two  and  one-half  inches  in  diameter  and  there  should  be  no  threshold; 
this  latter  is  a very  particular  point.  If  there  is  a threshold  or  place  to 
alight  upon,  the  sparrows  are  likely  to  dispute  with  the  bluebirds  and 
drive  them  away,  but  the  sparrow  does  not  care  for  a place  which  has  no 
threshold.  The  box  for  the  bluebird  may  be  made  out  of  old  boards  or 
may  be  a section  of  an  old  tree  trunk ; it  should  be  fastened  from  six  to 
fifteen  feet  above  the  ground,  and  should  be  in  nowise  noticeable  in  color 
from  its  surroundings.  To  protect  the  nest  from  cats,  barbed  wire  should 


Bird  Study 


61 


be  wound  around  the  tree  or  post  below  the  box.  If  the  box  for  the  nest 
is  placed  upon  a post  the  barbed  wire  will  also  protect  it  from  the  squirrels. 
The  eggs  are  bluish 
white;  the  young  birds, 
in  their  first  feathers,  are 
spotted  on  the  back  and 
have  whitish  breasts  mot- 
tled with  brown.  The 
food  of  the  nestlings  is 
almost  entirely  insects. 

In  fact,  this  bird  during 
its  entire  life  is  a great 
friend  to  man.  The  food 
of  the  adult  is  more  than 
three-fourths  insects  and 
the  remainder  is  wild 
berries  and  fruits,  the 
winter  food  being  largely 
mistletoe  berries.  It 
makes  a specialty  of  in- 
jurious beetles,  caterpil- 
lars and  grasshoppers, 
and  never  touches  any  of 
our  cultivated  fruits.  We 
should  do  everything  in  our  power  to  encourage  and  protect  these  birds 
from  their  enemies,  which  are  chiefly  cats,  squirrels  and  English  sparrows. 

The  migration  takes  place  in  flocks  during  autumn,  but  it  is  done  in  a 
most  leisurely  manner  with  frequent  stops  where  food  is  plenty.  The 
bluebirds  we  see  in  September  are  probably  not  the  ones  we  have  had  with 
us  during  the  summer,  but  are  those  which  have  come  from  farther  north. 

They  winter  largely  in  the  Gulf  States ; the  writer  has  often  heard  them 
singing  in  midwinter  in  Southern  Mississippi.  The  bluebirds  seem  to  be 
the  only  ones  that  sing  while  at  their  winter  resorts.  They  live  the  year 
round  in  the  Bermudas,  contrasting  their  heavenly  blue  plumage  with 
the  vivid  red  of  the  cardinals.  The  bluebird  should  not  be  confused  with 
the  indigo  bunting;  the  latter  is  darker  blue  and  has  a blue  breast.

LESSON  XI 
The  Bluebird 

Leading  thought— The  bluebird  is  related  to  the  robins  and  thrushes 
and  is  as  beneficial  as  it  is  beautiful.  We  should  study  its  habits  and 
learn  how  to  make  nesting  boxes  for  it,  and  protect  it  in  all  ways. 

Methods — The  observations  of  this  lesson  must  be  made  in  the  field 
and  by  the  pupils  individually.  Give  to  each  an  outline  of  questions  to 
answer  through  seeing.  There  should  follow  reading  lessons  on  the  blue- 
bird’s value  to  us  and  its  winter  migrations,  and  the  lesson  should  end  in 
discussions  of  best  way  to  build  boxes  for  its  use  in  nesting  season,  its 
protection  from  cats  and  other  enemies. 

Observations — i.  Which  comes  North  earlier  in  spring  the  robin  or 
the  bluebird? 

2.  How  do  the  two  resemble  each  other  and  differ  from  each  other  ? 

3.  Describe  the  bluebirds’  song.  Do  they  sing  all  summer? 

4.  Describe  the  colors  of  the  bluebird  as  follows:  The  head,  back, 

breast,  under  parts,  wings,  tail.  How  does  the  male  bluebird  differ  from 
his  mate  in  colors  ? 

5.  Where  were  the  bluebirds  you  saw?  What  were  they  doing? 
If  feeding,  how  did  they  act? 

6.  Can  you  see  the  color  of  the  bluebird  as  plainly  when  it  is  in  a tree 
as  when  it  is  flying?  If  not,  why? 

7.  Where  do  the  bluebirds  build  their  nests?  Of  what  material 
are  the  nests  made?  Do  both  parents  work  at  the  nest  building? 

8.  What  is  the  color  of  the  eggs?  How  do  the  young  birds  look, 
when  old  enough  to  leave  the  nest,  as  compared  with  their  parents? 

9.  What  do  the  bluebirds  eat?  How  do  they  benefit  us?  Do  they 
do  our  fruit  any  injury? 

10.  What  can  we  do  to  induce  the  bluebirds  to  live  near  our  houses? 
How  can  we  protect  them? 

11.  Where  do  the  bluebirds  spend  the  winter? 

12.  Make  a colored  picture  of  a bluebird.  How  can  we  tell  the 
bluebird  from  the  indigo  bunting?

THE  WHITE-BREASTED  NUTHATCH 

Teacher's  Story 

“ The  busy  nuthatch  climbs  his  tree 
Around  the  great  bole  spirally , 

Peeping  into  wrinkles  gray, 

U naer  ruffled  lichens  gay, 

Lazily  piping  one  sharp  note 
From  his  silver  mailed  throat 

— Maurice  Thompson. 

LIHTE  and  mellow  is  the  ringing  “ank,  ank”  note  of  the 
nuthatch,  and  why  need  we  allude  to  its  nasal  timbre! 
While  it  is  not  a strictly  musical  note,  it  has  a most  enticing 
quality  and  translates  into  sound  the  picture  of  bare- 
branched  trees  and  the  feeling  of  enchantment  which 
permeates  the  forest  in  winter;  it  is  one  of  the  most 
‘ ‘woodsy’  ’ notes  in  the  bird  repertoire.  And  while  the  singer 
of  this  note  is  not  so  bewitching  as  his  constant  chum 
the  chickadee,  yet  it  has  many  interesting  ways  quite  its 
own.  Nor  is  this  “ank,  ank,”  its  only  note.  I have  often 
heard  a pair  talking  to  each  other  in  sweet  confidential  syllables,  “wit, 
wit,  wit”  very  different  from  the  loud  note  meant  for  the  world  at  large. 
The  nuthatches  and  chickadees  hunt  together  all  winter;  it  is  no  mere 
business  partnership  but  a matter  of  congenial  tastes.  The  chickadees 
hunt  over  the  twigs  and  smaller  branches,  while  the  nuthatches  usually 
prefer  the  tree  trunks  and  the  bases  of  the  branches;  both  birds  like 
the  looks  of  the  world  upside  down,  and  while  the  chickadee  hangs 
head  down  from  a twig,  the  nuthatch  is  quite  likely  to  alight  head  down 
on  a tree  bole,  holding  itself  safely  in  this  position  by  thrusting  its  toes 
out  at  right  angles  to  the  body,  thus  getting  a firm  hold  upon  the  bark. 
Sometimes  its  foot  will  be  twisted  completely  around,  the  front  toes 
pointed  up  the  tree.  The  foot  is  well  adapted  for  clinging  to  the  bark  as 
the  front  toes  are  strong  and  the  hind  toe  is  very  long  and  is  armed  with 
a strong  claw.  Thus  equipped,  this  bird  runs  about  on  the  tree  so 
rapidly,  it  has  earned  the  name  of  “tree  mouse”.  It  often  ascends  a 
tree  trunk  spirally  but  is  not  so  hidebound  in  this  habit  as  is  the  brown 
creeper.  It  runs  up  or  down  freely  head  first  and  never  flops  down 
backwards  like  a woodpecker. 

In  color  the  nuthatch  is  bluish  gray  above  with  white  throat  and 
breast  and  reddish  underparts.  The  sides  of  the  head  are  white;  the 
black  cap  extends  back  upon  the  neck  but  is  not  “pulled  down”  to  the 
eyes  like  the  chickadees.  The  wing  feathers  are  dark  brown  edged 
with  pale  gray.  The  upper  middle  tail  feathers  are  bluish  like  the  back; 
the  others  are  dark  brown  and  tipped  with  white  in  such  a manner 
that  the  tail  when  spread  shows  a broad  white  border  on  both  sides. 
The  most  striking  contrast  between  the  chickadee  and  nuthatch  in 
markings  is  that  the  latter  lacks  the  black  bib.  However,  its  entire  shape 
is  very  different  from  that  of  the  chickadee  and  its  beak  is  long 
and  slender,  being  as  long  or  longer  than  its  head,  while  the  beak  of 
the  chickadee  is  a short,  sharp,  little  pick.  The  bill  of  the  nuthatch  is 
exactly  fitted  to  reach  in  crevices  of  the  bark  and  pull  out  hiding 
insects,  or  to  hammer  open  the  shell  of  nut  or  acorn  and  get  both  the 


64  Handbook  of  Nature-Study 

meat  of  the  nut  and  the  grub  feeding  upon  it.  It  will  wedge  an  acorn 
into  a seam  in  the  bark  and  then  throw  back  its  head,  woodpecker  fashion, 
and  drive  home. its  chisel  beak.  But  it  does  not  always  use  common 

sense  in  this  habit.  I have  often 
seen  one  cut  off  a piece  of  suet,  fly 
off  and  thrust  it  into  some  crevice 
and  hammer  it  as  hard  as  if  it  were 
encased  in  a walnut  shell.  This 
always  seems  bad  manners,  like 
carrying  off  fruit  from  table  d'hote; 
but  the  nuthatch  is  polite  enough  in 
using  a napkin,  for  after  eating  the 
suet,  it  invariably  wipes  its  bill  on  a 
branch,  first  one  side  then  the  other 
most  assiduously  until  it  is  perfectly 
clean. 

The  nuthatches  are  a great 
benefit  to  our  trees  in  winter,  for 
then  is  when  they  hunt  for  hiding 
pests  on  their  trunks.  Their  food 
consists  of  beetles,  caterpillars, 
pupae  of  various  insects,  also  seeds 
of  ragweed,  sunflowers,  acorns,  etc. 
While  the  nuthatch  finds  much  of 
its  food  on  trees,  yet  Mr.  Torrey  has  seen  it  awkwardly  turning  over 
fallen  leaves  hunting  for  insects,  and  Mr.  Baskett  says  it  sometimes 
catches  insects  on  the  wing  and  gets  quite  out  of  breath  from  this  un- 
usual exercise. 

It  is  only  during  the  winter  that  we  commonly  see  the  nuthatches,  for 
during  the  nesting  season,  they  usually  retire  to  the  deep  woods  where 
they  may  occupy  a cavity  in  a tree  used  by  a woodpecker  last  year,  or 
may  make  a hole  for  themselves  with  their  sharp  beaks.  The  nest  is  lined 
with  leaves,  feathers  and  hair;  from  five  to  nine  creamy,  speckled  eggs  are 
the  treasure  of  this  cave. 


The  white  breasted  nuthatch. 


LESSON  XII 
The  Nuthatch 

Leading  thought — The  nuthatch  is  often  a companion  of  the  chickadees 
and  woodpeckers.  It  has  no  black  bib,  like  the  chickadee,  and  it  alights 
on  a tree  trunk  head  downward,  which  distinguishes  it  from  woodpeckers. 

Methods — This  bird,  like  the  chickadee  and  downy,  gladly  shares  the 
suet  banquet  we  prepare  for  them  and  may  be  observed  at  leisure  while 
“at  table.”  The  contrast  between  the  habits  of  the  nuthatch  and  those 
of  its  companions  make  it  a most  valuable  aid  in  stimulating  close  and 
keen  observation  on  the  part  of  the  pupils. 

Observations — i.  Where  have  you  seen  the  nuthatches?  Were 
they  with  other  birds?  What  other  birds? 

2.  Does  a nuthatch  usually  alight  on  the  ends  of  the  branches  of  a 
tree  or  on  the  trunk  and  larger  limbs  ? Does  it  usually  alight  head  down 
or  up  ? When  it  runs  down  the  tree,  does  it  go  head  first  or  does  it  back 


Bird  Study  65 

down  ? When  it  ascends  the  tree  does  it  follow  a spiral  path  ? Does  it  use 
its  tail  for  a brace  when  climbing,  as  does  the  downy  ? 

3.  How  are  the  nuthatch’s  toes  arranged  to  assist  it  in  climbing? 
Are  the  three  front  toes  of  each  foot  directed  downward  when  the  bird 
alights  head  downward?  How  does  it  manage  its  feet  when  in  this 
position  ? 

4.  What  is  the  general  color  of  the  nuthatch  above  and  below? 
The  color  of  the  top  and  sides  of  head?  Color  of  Back?  Wings?  Tail? 
Throat?  Breast? 

5.  Does  the  black  cap  come  down  to  the  eyes  on  the  nuthatch  as 
on  the  chickadee?  Has  the  nuthatch  a black  bib? 

6.  What  is  the  shape  of  the  beak  of  the  nuthatch?  For  what  is  it 
adapted?  How  does  it  differ  from  the  beak  of  the  chickadee? 

7.  What  is  the  food  of  the  nuthatch?  Where  is  it  found?  Does  it 
open  nuts  for  the  grubs  or  the  nut  meat  ? Observe  the  way  it  strikes  its 
beak  into  the  suet,  why  does  it  strike  so  hard? 

8.  How  would  you  spell  this  bird’s  note?  Have  you  heard  it  give 
more  than  one  note? 

9.  How  does  the  nuthatch  benefit  our  trees?  At  what  season  does 
it  benefit  them  most  ? Why  ? 

10.  Where  do  the  nuthatches  build  their  nests?  Why  do  we  see 
the  nuthatches  oftener  in  winter  than  in  summer?

THE  CHICKADEE 

Teacher's  Story 

“ He  is  the  hero  of  the  woods;  there  are  courage  and  good  nature  enough  in  that  com- 
pact little  body , which  you  may  hide  in  your  fist,  to  supply  a whole  groveful  of  May 
songsters.  He  has  the  Spartan  virtue  of  an  eagle,  the  cheerfulness  of  a thrtish,  the 
nimbleness  of  Cock  Sparrow,  the  endurance  of  the  sea-birds  condensed  into  his  tiny 
frame,  and  there  have  been  added  a pertness  and  ingenuity  all  his  own.  His  curiosity 
is  immense , and  his  audacity  equal  to  it;  I have  even  had  one  alight  upon  the  barrel  of 
the  gun  over  my  shoulders  as  I sat  quietly  under  his  tree.” 

— Ernest  Ingersoll. 

OWEVER  careless  we  may  be  of  our  bird  friends 
when  we  are  in  the  midst  of  the  luxurious  life  of 
summer,  even  the  most  careless  among  us  give 
pleased  attention  to  the  birds  that  bravely  endure 
with  us  the  rigors  of  winter.  And  when  this 
winged  companion  of  winter  proves  to  be  the  most 
fascinating  little  ball  of  feathers  ever  created,  constantly  overflowing 
with  cheerful  song,  our  pleased  attention  changes  to  active  delight. 
Thus  it  is,  that  in  all  the  lands  of  snowy  winters  the  chickadee  is  a loved 
comrade  of  the  country  wayfarer;  that  happy  song  “chick-a-dee-dee-dee” 
finds  its  way  to  the  dullest  consciousness  and  the  most  callous  heart. 

The  chickadees  appear  in 
small  flocks  in  the  winter  and 
often  in  company  with  the  nut- 
hatches. The  chickadees  work 
on  the  twigs  and  ends  of  bran- 
ches, while  the  nuthatches 
usually  mine  the  bark  of  the 
trunk  and  larger  branches,  the 
former  hunting  insect  eggs  and 
the  latter,  insects  tucked  away 
in  winter  quarters.  When  the 
chickadee  is  prospecting  for  eggs, 
it  looks  the  twig  over,  first  above 
and  then  hangs  head  down  and 
inspects  it  from  below;  it  is  a 
thorough  worker  and  doesn’t 
intend  to  overlook  anything 
whatever ; and  however  busily  it 
is  hunting,  it  always  finds  time 
for  singing;  whether  on  the  wing 
or  perched  upon  a twig  or  hang- 
ing from  it  like  an  acrobat, 
head  down,  it  sends  forth  its 
happy  “chickadeedee”  to  assure 
us  that  this  world  is  all  right  and 
good  enough  for  anybody.  Be- 
sides this  song,  it  begins  in 

February  to  sing  a most  seduc-  Chick-a-dee-dee-dee 

tive  “fee-bee,”  giving  a rising 


Bird  Study 


67 


inflection  to  the  first  syllable  and  a long,  falling  inflection  to  the  last, 
which  makes  it  a very  different  song  from  the  short,  jerky  notes  of  the 

phcebe-bird,  which  cuts 
the  last  syllable  short 
and  gives  it  a rising  in- 
flection. More  than  this, 
the  chickadee  has  some 
chatty  conversational 
notes,  and  now  and  then 
performs  a bewitching 
little  yodle,  which  is  a fit 
expression  of  its  own 
delicious  personality. 

The  general  effect  of 
the  colors  of  the  chicka- 
dee is  grayish  brown 
above  and  grayish  white 
below.  The  top  of  the 
head  is  black,  the  sides 
white,  and  it  has  a 
seductive  little  black 
bib  under  its  chin.  The 
back  is  grayish,  the 
wings  and  tail  are  dark 
gray,  the  feathers  having 
white  margins.  The 
breast  is  grayish  white 
changing  to  b u ff  or 
brownish  at  the  sides 
and  below.  It  is  often 
called  the  “Black-capped  Titmouse,”  and  it  may  always  be  distin- 
guished by  black  cap  and  black  bib.  It  is  smaller  than  the  English 
sparrow;  its  beak  is  a sharp  little  pick  just  fitted  for  taking  insect  eggs 
off  twigs  and  from  under  bark.  Insects  are  obliged  to  pass  the  winter 
in  some  stage  of  their  existence,  and  many  of  them  wisely  remain 
in  the  egg  until  there  is  something  worth  doing  in  the  way  of  eating. 
These  eggs  are  glued  fast  to  the  food  trees  by  the  mother  insect  and 
thus  provides  abundant  food  for  the  chickadees.  It  has  been 
estimated  that  one  chickadee  will  destroy  several  hundred  insect 
eggs  in  one  day,  and  it  has  been  proven  that  orchards  frequented  by  these 
birds  are  much  more  free  from  insect  pests  than  other  orchards  in  the 
same  locality.  They  can  be  enticed  into  orchards  by  putting  up  beef  fat 
or  bones  and  thus  we  can  secure  their  valuable  service.  In  summer  these 
birds  attack  caterpillars  .and  other  insects. 

When  it  comes  to  nest  building,  if  the  chickadees  cannot  find  a house 
to  rent  they  proceed  to  dig  out  a proper  hole  from  some  decaying  tree, 
which  they  line  with  moss,  feathers,  fur  or  some  other  soft  material. 
The  nest  is  often  not  higher  than  six  to  ten  feet  from  the  ground.  One 
which  I studied  was  in  a decaying  fence  post.  The  eggs  are  white, 
sparsely  speckled  and  spotted  with  lilac  or  rufous.  The  young  birds  are 
often  eight  in  number  and  how  these  fubsy  birdlings  manage  to  pack 
themselves  in  such  a small  hole  is  a wonder,  and  probably  gives  them  good 
discipline  in  bearing  hardships  cheerfully.

LESSON  XIII 

The  Chickadee 

Leading  thought — The  chickadee  is  as  useful  as  it  is  delightful;  it 
remains  in  the  North  during  winter,  working  hard  to  clear  our  trees  of 
insect  eggs  and  singing  cheerily  all  day.  It  is  so  friendly  that  we  can 
induce  it  to  come  even  to  the  window  sill,  by  putting  out  suet  to  show  our 
friendly  interest. 

Methods — Put  beef  fat  on  the  trees  near  the  schoolhouse  in  December 
and  replenish  it  afresh  about  every  two  or  three  weeks.  The  chick- 
adees will  come  to  the  feast  and  may  be  observed  all  winter.  Give  the 
questions  a few  at  a time  and  let  the  children  read  in  the  bird  books  a 
record  of  the  benefits  derived  from  this  bird. 

Observations — 1.  Where  have  you  seen  the  chickadees?  What 
were  they  doing?  Were  there  several  together? 

2.  What  is  the  common  song  of  the  chickadee?  What  other  notes 
has  it?  Have  you  heard  it  yodle?  Have  you  heard  it  sing  “fe-bee,  fee- 
bee.”  Flow  does  this  song  differ  from  that  of  the  phoebe-bird?  Does  it 
sing  on  the  wing  or  when  at  rest? 

3.  What  is  the  color  of  the  chickadee:  Top  and  sides  of  head, 

back,  wings,  tail,  throat,  breast,  under  parts? 

Compare  size  of  chickadee  with  that  of  English  sparrow. 

4.  What  is  the  shape  of  the  chickadee’s  bill  and  for  what  is  it 
adapted?  What  is  the  food  in  winter?  Where  does  the  bird  find  it? 
How  does  it  act  when  feeding  and  hunting  for  food? 

5.  Does  the  chickadee  usually  alight  on  the  ends  of  the  branches  or 
on  the  larger  portions  near  the  trunk  of  the  tree? 

6.  How  can  you  distinguish  the  chickadees  from  their  companions, 
the  nuthatches? 

7.  Does  the  chickadee  ever  seem  discouraged  by  the  snow  and  cold 
weather?  Do  you  know  another  name  for  the  chickadee? 

8.  Where  does  it  build  its  nest?  Of  what  material?  Have  you 
ever  watched  one  of  these  nests?  If  so,  tell  about  it. 

9.  How  does  the  chickadee  benefit  our  orchards  and  shade  trees? 
How  can  we  induce  it  to  feel  at  home  with  us  and  work  for  us?

THE  DOWNY  WOODPECKER 
Teacher's  Story 

1 RIEND  Downy  is  the  name  this  attractive  little  neighbor 
has  earned,  because  it  is  so  friendly  to  those  of  us  who 
love  trees.  Watch  it  as  it  hunts  each  crack  and  crevice 
of  the  bark  of  your  favorite  apple  or  shade  tree,  seeking 
assiduously  for  cocoons  and  insects  hiding  there,  and 
you  will  soon,  of  your  own  accord,  call  it  friend;  you 
will  soon  love  its  black  and  white  uniform,  which  consists  of  a black  coat 
speckled  and  barred  with  white  and  whitish  gray  vest  and  trousers.  The 
front  of  the  head  is  black  and  there  is  a black  streak  extending  backward 
from  the  eye  with  a white  streak  above  and  also  below  it.  The  male  has 
a vivid  red  patch  on  the  back  of  the  head,  but  his  wife  shows  no  such 
giddiness ; plain  black  and  white  are  good  enough  for  her.  In  both 
sexes  the  throat  and  breast  are  white,  the  middle  tail  feathers  black, 
while  the  side  tail  feathers  are  white,  barred  with  black  at  their  tips. 

The  downy  has  a way  of  alighting  low  down  on  a tree  trunk  or  at  the 
base  of  a larger  branch  and  climbing  upward  in  a jerky  fashion;  it  never 
runs  about  over  the  tree  nor  does  it  turn  around  and  go  down  head  first, 
like  the  nuthatch ; if  it  wishes  to  go  down  a short  distance  it  accomplishes 
this  by  a few  awkward,  backward  hops;  but  when  it  really  wishes  to 
descend,  it  flies  off  and  down.  The  downy,  as  other  woodpeckers,  has  a 
special  arrangement  of  its  physical  machinery  to  enable  it  to  climb 
trees  in  its  own  manner.  In  order  to  grasp  the  bark  on  the  side  of  the 
tree  more  firmly,  its  fourth  toe  is  turned  backward 
to  work  as  companion  with  the  thumb.  Thus  it  is 
able  to  clutch  the  bark  as  with  a pair  of  nippers, 
two  claws  in  front  and  two  claws  behind ; and 
as  another  aid,  the  tail  is  arranged  to  prop  the 
bird,  like  a bracket.  The  tail  is  rounded  in  ^ 

shape  and  the  middle  feathers  have  rather  strong  ’ , , . 

quills;  but  the  secret  of  the  adhesion  of  the  tail  F™nd  Downy  s foot. 
to  the  bark  lies  in  the  great  profusion  of  barbs  which,  at  the  edge 
of  the  feathers,  offer  bristling  tips,  and  when  applied  to  the  side 
of  the  tree  act  like  a wire  brush  with  all  the  wires  pushing  downward. 
This  explains  why  the  woodpecker  cannot  go  backward  without  lifting 
the  tail. 

But  even  more  wonderful  than  this,  is  the  mechanism  by  which 
the  downy  and  hairy  woodpeckers  get  their  food,  which  consists 
largely  of  wood-borers  or  larvae  working  under  the  bark.  When  the 
woodpecker  wishes  to  get  a grub  in  the  wood,  it  seizes  the  bark  firmly 
with  its  feet,  uses  its  tail  as  a brace,  throws  its  head  and  upper  part  of 
the  body  as  far  back  as  possible,  and  then  drives  a powerful  blow 
with  its  strong  beak.  The  beak  is  adapted  for  just  this  purpose, 
as  it  is  wedge-shaped  at  the  end,  and  is  used  like  a mason’s  drill 
sometimes,  and  sometimes  like  a pick.  When  the  bird  uses  its  beak  as  a 
pick,  it  strikes  hard,  deliberate  blows  and  the  chips  fly;  but  when  it  is 
drilling,  it  strikes  rapidly  and  not  so  hard  and  quickly  drills  a small, 
deep  hole  leading  directly  to  the  burrow  of  the  grub.  When  finally  the 
grub  is  reached,  it  would  seem  well  nigh  impossible  to  pull  it  out 
through  a hole  which  is  too  small  and  deep  to  admit  of  the  beak 


7o 


Handbook  of  Nature-Study 


being  used  as  pincers.  This  is  another  story  and  a very  interesting 
one ; the  downy  and  hairy  can  both  extend  their  tongues  far  beyond  the 
point  of  the  beak,  and  the  tip  of  the 
tongue  is  hard  and  homy  and  covered 
^dth  short  backward-slanting  hooks 
acting  like  a spear  or  harpoon,  and 
when  thrust  into  the  grub  pulls  it  out 
easily  (see  initial) . The  bones  of  the 
tongue  have  a spring  arrangement; 
when  not  in  use,  the  tongue  lies  soft  in 
the  mouth,  like  a wrinkled  earth- 
worm, but  when  in  use,  the  bones 
spring  out,  stretching  it  to  its  full 
length  and  it  is  then  slim  and  small. 

The  process  is  like  fastening  a pencil 
to  the  tip  of  a glove  finger ; when 
drawn  back  the  finger  is  wrinkled 
together,  but  when  thrust  out, 
straightens.  This  spring  arrangement 
of  the  bones  of  the  woodpecker’s 
tongue  is  a marvellous  mechanism 
and  should  be  studied  through  pic- 
tures; see  Birds,  Eckstrom,  Chap- 
ter XIV;  The  Bird,  Beebe,  p.122; 

“The  Tongues  of  Woodpeckers,” 

Lucas,  U.  S.  Department  of  Agricul- 
ture. 

Since  the  food  of  the  downy  and 
the  hairy  is  where  they  can  get  it  all  winter,  there  is  no  need  for  them  to 
go  South;  thus  they  stay  with  us  and  work  for  us  the  entire  year.  We 
should  try  to  make  them  feel  at  home  with  us  in  our  orchards  and  shade 
trees  by  putting  up  pieces  of  beef  fat,  to  convince  them  of  their  welcome. 
No  amount  of  free  food  will  pauperize  these  birds,  for  as  soon  as  they 
have  eaten  of  the  fat,  they  commence  to  hunt  for  grubs  on  the  tree  and 
thus  earn  their  feast.  They  never  injure  live  wood. 

James  Whitcomb  Riley  describes  the  drumming  of  the  woodpecker  as 
“weeding  out  the  lonesomeness”  and  that  is  exactly  what  the  drumming 
of  the  woodpecker  means.  The  male  selects  some  dried  limb  of  hard 
wood  and  there  beats  out  his  well-known  signal  which  advertises  far  and 
near,  “Wanted,  a wife.”  And  after  he  wins  her,  he  still  drums  on  for  a 
time  to  cheer  her  while  she  is  busy  with  her  family  cares.  The  wood- 
pecker has  no  voice  for  singing,  like  the  robin  or  thrush ; and  luckily,  he 
does  not  insist  on  singing,  like  the  peacock  whether  he  can  or  not.  He 
chooses  rather  to  devote  his  voice  to  terse  and  business-like  conversation ; 
and  when  he  is  musically  inclined,  he  turns  drummer.  He  is  rather 
particular  about  his  instrument  and  having  found  one  that  is  sufficiently 
resonant  he  returns  to  it  day  after  day.  While  it  is  ordinarily  the  male 
that  drums  I once  observed  a female  drumming.  I told  her  that  she  was 
a bold  minx  and  ought  to  be  ashamed  of  herself;  but  within  twenty 
minutes  she  had  drummed  up  two  red-capped  suitors  who  chased  each 
other  about  with  great  animosity,  so  her  performance  was  evidently  not 
considered  improper  in  woodpecker  society.  I have  watched  a rival  pair

of  male  downies  fight  for  hours  at  a time,  but  their  duel  was  of  the  French 
brand, — much  fuss  and  no  bloodshed.  They  advanced  upon  each  other 
with  much  haughty  glaring  and  scornful  bobs  of  the  head,  but  when  they 
were  sufficiently  near  to  stab  each  other  they  beat  a mutual  and  circum- 
spect retreat.  Although  we  hear  the  male  downies  drumming  every 
spring,  I doubt  if  they  are  calling  for  new  wives ; I believe  they  are,  in- 
stead. calling  the  attention  of  their  lawful  spouses  to  the  fact  that  it  is 
time  for  nest  building  to  begin.  I have  come  to  this  conclusion  because 
the  downies  and  hairies  which  I have  watched  for  years  have  always  come 
in  pairs  to  partake  of  suet  during  the  entire  winter;  and  while  only  one  at 
a time  sits  at  meat  and  the  lord  and  master  is  somewhat  bossy,  yet  they 
seem  to  get  along  as  well  as  most  married  pairs. 

The  downy’s  nest  is  a hole,  usually  in  a partly  decayed  tree;  an  old 
apple  tree  is  a favorite  site  and  a fresh  excavation  is  made  each  year. 
There  are  from  four  to  six  white  eggs,  which  are  laid  on  a nice  bed  of  chips 
as  fine  almost  as  sawdust.  The  door  to  the  nest  is  a perfect  circle  and 
about  an  inch  and  a quarter  across. 

The  hairy  woodpecker  is  fully  one-third  larger  than  the  downy, 
measuring  nine  inches  from  tip  of  beak  to  tip  of  tail,  while  the  downy 
measures  only  about  six  inches.  The  tail  feathers  at  the  side  are  white 
for  the  entire  length,  while  they  are  barred  at  the  tips  in  the  downy. 
There  is  a black  “parting”  through  the  middle  of  the  red  patch  on  the 
back  of  the  hairy’s  head.  The  two  species  are  so  much  alike  that  it  is 
difficult  for  the  beginner  to  tell  them  apart.  Their  habits  are  very 
similar,  except  that  the  hairy  lives  in  the  woods  and  is  not  so  commonly 
seen  in  orchards  or  on  shade  trees.  The  food  of  the  hairy  is  much  like 
that  of  the  downy  and  it  is,  therefore,  a beneficial  bird  and  should  be 
protected. 

LESSON  XIV 
The  Downy  Woodpecker 

Leading  thought — The  downy  woodpecker  remains  with  us  all  winter, 
feeding  upon  insects  that  are  wintering  in  crevices  and  beneath  the  bark 
of  our  trees.  It  is  fitted  especially  by  shape  of  beak,  tongue,  feet  and  tail 
to  get  such  food  and  it  is  a “friend  in  need”  to  our  forest,  shade  and 
orchard  trees. 

Methods — If  a piece  of  beef  fat  be  fastened  upon  the  trunk  or  branch 
of  a tree,  which  can  be  seen  from  the  schoolroom  windows,  there  will  be 
no  lack  of  interest  in  this  friendly  little  bird;  for  the  downy  will  sooner 
or  later  find  this  feast  spread  for  it  and  will  come  every  day  to  partake. 
Give  out  the  questions,  a few  at  a time,  and  discuss  the  answers  with  the 
pupils. 

Observations — 1 . What  is  the  general  color  of  the  downy  above  and 
below?  The  color  of  the  top  of  the  head?  Sides  of  the  head?  The 
throat  and  breast?  The  color  and  markings  of  the  wings?  Color  and 
markings  of  the  middle  and  side  tail-feathers  ? 

2.  Do  all  downy  woodpeckers  have  the  red  patch  at  the  back  of  the 
head  ? If  not,  why  ? 

3.  What  is  the  note  of  the  downy?  JDoes  it  make  any  other  sound? 
Have  you  ever  seen  one  drumming?  At  what  time  of  the  year?  On 
what  did  it  drum  ? What  did  it  use  for  a drumstick  ? What  do  you  sup- 
pose was  the  purpose  of  this  music?

A few  seasons  ago  a downy  woodpecker , probably  the  individual  one  who  is  now 
my  winter  neighbor,  began  to  drum  early  in  March  in  a partly  decayed  apple-tree 
that  stands  in  the  edge  of  a narrow  strip  of  woodland  near  me.  When  the  morning 
was  still  and  mild  I would  often  hear  him  through  my  window  before  I was  up,  or  by 
half-past  six  o'clock,  and  he  would  keep  it  up  pretty  briskly  till  nine  or  ten  o'clock, 
in  this  respect  resembling  the  grouse,  which  do  most  of  their  drumming  in  the  forenoon. 
His  drum  was  the  stub  of  a dry  limb  about  the  size  of  one's  wrist.  The  heart  was 
decayed  and  gone , but  the  outer  shell  was  loud  and  resonant.  The  bird  would  keep 
his  position  there  for  an  hour  at  a time.  Between  his  drummings  he  would  preen  his 
plumage  and  listen  as  if  for  the  response  of  the  female,  or  for  the  drum  of  some  rival. 
How  swift  his  heady  would  go  when  he  was  delivering  his  blows  upon  the  limb!  His 
beak  wore  the  surface  perceptibly.  When  he  wished  to  change  the  key,  which  was  quite 
often,  he  would  shift  his  position  an  inch  or  two  to  a knot  which  gave  out  a higher, 
shriller  note.  When  I climbed  up  to  examine  his  drum  he  was  much  disturbed.  I did 
not  know  he  was  in  the  vicinity,  but  it  seems  he  saw  me  from  a near  tree,  and  came 
in  haste  to  the  neighboring  branches,  and  with  spread  plumage  and  a sharp  note  de- 
manded plainly  enough  what  my  business  was  with  his  drum.  I was  invading  his 
privacy,  desecrating  his  shrine,  and  the  bird  was  much  put  out.  After  some  weeks 
the  female  appeared;  he  had  literally  drummed  up  a mate;  his  urgent  and  oft-repeated 
advertisement  was  answered.  Still  the  drumming  did  not  cease,  but  was  quite  as 
fervent  as  before.  If  a mate  could  be  won  by  drumming  she  could  be  kept  and  enter- 
tained by  more  drumming;  courtship  should  not  end  with  marriage.  If  the  bird  felt 
musical  before,  of  course  he  felt  much  more  so  now.  Besides  that,  the  gentle  deities 
needed  propitiating  in  behalf  of  the  nest  and  young  as  well  as  in  behalf  of  the  mate. 
After  a time  a second  female  came,  when  there  was  war  between  the  two.  I did  not  see 
them  come  to  blows,  but  I saw  one  female  pursuing  the  other  about  the  place,  and  giving 
her  no  rest  for  several  days.  She  was  evidently  trying  to  run  her  out  of  the  neighbor- 
hood. Now  and  then  she,  too,  would  drum  briefly  as  if  sending  a triumphant  message 
to  her  mate. — Winter  Neighbors,  John  Burroughs.

THE  SAPSUCKER 

Teacher’s  Story 

The  sapsucker  is  a woodpecker 
that  has  strayed  from  the  paths  of 
virtue;  he  has  fallen  into  tempta- 
tion by  the  wayside,  and  instead  of 
drilling  a hole  for  the  sake  of  the 
grub  at  the  end  of  it,  he  drills  for 
drink.  He  is  a tippler,  and  sap  is 
his  beverage ; and  he  is  also  fond  of 
the  soft,  inner  bark.  He  often 
drills  his  holes  in  regular  rows  and 
thus  girdles  a limb  or  a tree,  and  for 
this  is  pronounced  a rascal  by  men 
who  have  themselves  ruthlessly  cut 
from  our  land  millions  of  trees  that 
should  now  be  standing.  It  is 
amusing  to  see  a sapsucker  take  his 
tipple,  unless  his  saloon  happens  to 
be  one  of  our  prized  young  trees. 

He  uses  his  bill  as  a pick  and  makes 
the  chips  fly  as  he  taps  the  tree; 
then  he  goes  away  and  taps  another 
tree.  After  a time  he  comes  back 
and  holding  his  beak  close  to  the 
hole  for  a long  time  seems  to  be 
sucking  up  the  sap ; he  then  throws 
back  his  head  and  “swigs”  it  down 
with  every  sign  of  delirious  enjoyment.  The  avidity  with  which  these 
birds  come  to  the  bleeding  wells  which  they  have  made,  has  in  it  all  the 
fierceness  of  a toper  crazy  for  drink;  they  are  particularly  fond  of  the  sap 
of  the  mountain  ash,  apple,  thorn  apple,  canoe  birch,  cut-leaf  birch,  red 
maple,  red  oak,  white  ash  and  young  pines.  However,  the  sapsucker 
does  not  live  solely  on  sap,  he  also  feeds  upon  insects  whenever  he  can 
find  them.  When  feeding  their  young,  the  sapsuckers  are  true  fly- 
catchers snatching  insects  while  on  the  wing.  The  male  has  the  crown 
and  throat  crimson,  edged  with  black  with  a black  line  extending  back  of 
the  eye,  bordered  with  white  above  and  below.  There  is  a large,  black 
circular  patch  on  the  breast  which  is  bordered  at  the  sides  and  below  with 
lemon  yellow.  The  female  is  similar  to  the  male  and  has  a red  forehead, 
but  she  has  a white  bib  instead  of  a red  one  beneath  the  chin.  The 
distinguishing  marks  of  the  sapsucker  should  be  learned  by  the  pupils. 
The  red  is  on  the  front  of  the  head  instead  of  on  the  crown,  as  is  the  case 
with  the  downy  and  hairy;  when  it  is  flying  the  broad,  white  stripes 
extending  from  the  shoulders  backward,  form  a long,  oval  figure,  which  is 
very  characteristic. 

The  sapsuckers  spend  the  winter  in  the  Southern  States  where  they 
drill  wells  in  the  white  oak  and  other  trees.  From  Virginia  to  Northern 
New  York  and  New  England,  where  they  breed,  they  are  seen  only  during 
migration,  which  occurs  in  April;  then  the  birds  appear  two  and  three 
together  and  are  very  bold  in  attacking  shade  trees,  especially  the  white

birch.  They  nest  only  in  the  Northern  United  States  and  northward. 
The  nest  is  usually  a hole  in  a tree  about  forty  feet  from  the  ground,  and 
is  likely  to  be  in  a dead  birch. 


LESSON  XV 
The  Sapsucker 

Leading  thought — The  sapsucker  has  a red  cap,  a red  bib  and  a yel- 
low breast;  it  is  our  only  woodpecker  that  does  injury  to  trees.  We 
should  learn  to  distinguish  it  from  the  downy  and  hairy,  as  the  latter  are 
among  the  best  bird  friends  of  the  trees. 

Methods — Let  the  observations  begin  with  the  study  of  the  trees  which 
have  been  attacked  by  the  sapsucker,  which  are  almost  everywhere 
common,  and  thus  lead  to  an  interest  in  the  culprit. 

Observations — i.  Have  you  seen  the  work  of  the  sapsucker?  Are 
the  holes  drilled  in  rows  completely  around  the  tree?  If  there  are  two 
rows  or  more,  are  the  holes  set  evenly  one  below  another? 

2.  Do  the  holes  sink  into  the  wood,  or  are  they  simply  through  the 
bark?  Why  does  it  injure  or  kill  a tree  to  be  girdled  with  these  holes? 
Have  you  ever  seen  the  sapsuckers  making  these  holes?  If  so,  how  did 
they  act  ? 

3 . How  many  kinds  of  trees  can  you  find  punctured  by  these  holes  ? 
Are  they  likely  to  be  young  trees  ? 

4.  How  can  you  distinguish  the  sapsucker  from  the  other  wood- 
peckers? How  have  the  hairy  and  downy  which  are  such  good  friends  of 
the  trees  been  made  to  suffer  for  the  sapsucker’s  sins? 

5.  What  is  the  color  of  the  sapsucker  as  follows:  Forehead,  sides 

of  head,  back,  wings,  throat,  upper  and  lower  breast?  What  is  the 
difference  in  color  between  the  male  and  female? 

6.  In  what  part  of  the  country  do  the  sapsuckers  build  their  nests? 
Where  do  they  make  their  nests  and  how?

Sharp  Eyes,  John  Burroughs. 


In  the  following  winter  the  same  bird  ( a sapsucker)  tapped  a maple-tree  in  front 
of  my  window  in  fifty-six  places;  and,  when  the  day  was  sunny  and  the  sap  oozed  out 
he  spent  most  of  his  time  there.  He  knew  the  good  sap-days,  and  was  on  hand  promptly 
for  his  tipple;  cold  and  cloudy  days  he  did  not  appear.  He  knew  which  side  of  the 
tree  to  tap,  too,  and  avoided  the  sunless  northern  exposure.  When  one  series  of  well- 
holes  failed  to  supply  him,  he  would  sink  another , drilling  through  the  bark  with  great 
ease  and  quickness.  Then,  when  the  day  was  warm,  and  the  sap  ran  freely,  he  would 
have  a regular  sugar-maple  debauch,  sitting  there  by  his  wells  hour  after  hour,  and  as 
fast  as  they  became  filled  sipping  out  the  sap.  This  he  did  in  a gentle,  carressing 
manner  that  was  very  suggestive.  He  made  a row  of  wells  near  the  foot  of  the  tree,  and 
other  rows  higher  up,  and  he  would  hop  up  and  down  the  trunk  as  they  became  filled. —

THE  RED-HEADED  WOODPECKER 

Teacher's  Story 

The  red-head  is  well  named,  for  his 
helmet  and  visor  show  a vivid  glow- 
ing crimson  that  stirs  the  sensibili- 
ties of  the  color  lover.  It  is 
readily  distinguished  from  the  other 
woodpeckers  because  its  entire  head 
and  bib  are  red.  For  the  rest,  it  is 
a beautiful  dark  metallic  blue  with 
the  lower  back,  a band  across  the 
wing,  and  the  under  parts  white; 
its  outer  tail  feathers  are  tipped 
with  white.  The  female  is  colored 
like  the  male,  but  the  young  have 
the  head  and  breast  gray,  streaked 
with  black  and  white,  and  the 
wings  barred  with  black.  It  may 
make  its  nest  by  excavating  a hole 
in  a tree  or  a stump  or  even  in  a 
telegraph  pole;  the  eggs  are  glossy 
white.  This  woodpecker  is  quite 
different  in  habits  from  the  hairy 
and  downy,  as  it  likes  to  flit  along 
from  stump  to  fence-post  and 
catch  insects  on  the  wing,  like  a 
fly-catcher.  The  only  time  that  it  pecks  wood  is  when  it  is  making  a hole 
for  its  nest. 

As  a drummer,  the  red-head  is  most  adept  and  his  roll  is  a long  one. 
He  is  an  adaptable  fellow,  and  if  there  is  no  resonant  dead  limb  at  hand, 
he  has  been  known  to  drum  on  tin  roofs  and  lightning  rods ; and  once  we 
also  observed  him  executing  a most  brilliant  Solo  on  the  wire  of  a barbed 
fence.  He  is  especially  fond  of  beechnuts  and  acorns,  and  being  a thrifty 
fellow  as  well  as  musical,  in  time  of  plenty  he  stores  up  food  against  time 
of  need.  He  places  his  nuts  in  crevices  and  forks  of  the  branches  or  in 
holes  in  trees  or  any  other  hiding  place.  He  can  shell  a beechnut  quite 
as  cleverly  as  can  the  deer  mouse ; and  he  is  own  cousin  to  the  Carpenter 
Woodpecker  of  the  Pacific  Coast,  which  is  also  red-headed  and  which  drills 
holes  in  the  oak  trees  wherein  he  drives  acorns  like  pegs  for  later  use. 


LESSON  XVI 

The  Red-headed  Woodpecker 

Leading  thought — The  red-headed  woodpecker  has  very  different  habits 
from  the  downy  and  is  not  so  useful  to  us.  It  lives  upon  nuts  and  fruit 
and  such  insects  as  it  can  catch  upon  the  wing. 

Methods — If  there  is  a red-head  in  the  vicinity  of  your  school  the 
children  will  be  sure  to  see  it.  Write  the  following  questions  upon  the 
blackboard  and  offer  a prize  to  the  first  one  who  will  make  a note  on 
where  the  red-head  stores  his  winter  food. 


76 


Handbook  of  Nature-Study 


Observations — i.  Can  you  tell  the  red-head  from  the  other  wood- 
peckers? What  colors  especially  mark  his  plumage? 

2.  Where  does  the  red-head  nest?  Describe  eggs  and  nest? 

3.  What  have  you  observed  the  red-head  eating?  Have  you 
noticed  it  storing  nuts  and  acorns  for  the  winter?  Have  you  noticed  it 
flying  off  with  cherries  or  other  fruit? 

4.  What  is  the  note  of  the  red-head?  Have  you  ever  seen  one 
drumming?  What  did  he  use  for  a drum?  Did  he  come  back  often  to 
this  place  to  make  his  music? 

Supplementary  reading — “The  House  That  Fell”  in  Nestlings  of  Forest 
and  Marsh;  Our  Birds  and  their  Nestlings,  p.  90;  Birds,  Bees  and 
Sharp  Eyes,  John  Burroughs. 


Another  trait  our  woodpeckers  have  that  endears  them  to  me,  and  that  has  never  been 
pointedly  noticed  by  our  ornithologists,  is  their  habit  of  drumming  in  the  spring.  They 
are  songless  birds,  and  yet  all  are  musicians;  they  make  the  dry  limbs  eloquent  of  the 
coming  change.  Did  you  think  that  loud,  sonorous  hammering  which  proceeded  from 
the  orchard  or  from  the  near  woods  on  that  still  March  or  April  morning  was  only  some 
bird  getting  its  breakfast f It  is  downy,  but  he  is  not  rapping  at  the  door  of  a grub; 
he  is  rapping  at  the  door  of  spring,  and  the  dry  limb  thrills  beneath  the  ardor  of  his 
blows.  Or,  later  in  the  season,  in  the  dense  forest  or  by  some  remote  mountain  lake, 
does  that  measured  rhythmic  beat  that  breaks  upon  the  silence,  first  three  strokes  follow- 
ing each  other  rapidly,  succeeded  by  two  louder  ones  with  longer  intervals  between  them, 
and  that  has  an  effect  upon  the  alert  ear  as  if  the  solitude  itself  had  at  least  found  a 
voice — does  that  suggest  anything  less  than  a deliberate  musical  performance?  In 
fact,  our  woodpeckers  are  just  as  characteristically  drummers  as  is  the  ruffed  grouse, 
and  they  have  their  particular  limbs  and  stubs  to  which  they  resort  for  that  purpose. 
Their  need  of  expression  is  apparently  just  as  great  as  that  of  the  song-birds,  and  it 
is  not  surprising  that  they  should  have  found  out  that  there  is  music  in  a dry,  seasoned 
limb  which  can  be  evoked  beneath  their  beaks. 

The  woodpeckers  do  not  each  have  a particular  dry  limb  to  which  they  resort  at  all 
times  to  drum,  like  the  one  I have  described.  The  woods  are  full  of  suitable  branches, 
and  they  drum  more  or  less  here  and  there  as  they  are  in  quest  of  food;  yet  I am  con- 
vinced each  one  has  its  favorite  spot,  like  the  grouse,  to  which  it  resorts,  especially  in 
the  morning.  The  sugar-maker  in  the  maple  woods  may  notice  that  this  sound  pro- 
ceeds from  the  same  tree  or  trees  about  his  camp  with  great  regularity.  A woodpecker 
in  my  vicinity  has  drummed  for  two  seasons  on  a telegraph-pole,  and  he  makes  the  wires 
and  glass  insulators  ring.  Another  drums  on  a thin  board  on  the  end  of  a long  grape- 
arbor,  and  on  still  mornings  can  be  heard  a long  distance. 

A friend  of  mine  in  a Southern  city  tells  me  of  a red  headed  woodpecker  that  drums 
upon  a lightning-rod  on  his  neighbor's  house.  Nearly  every  clear,  still  morning  at 
certain  seasons,  he  says,  this  musical  rapping  may  be  heard.  “He  alternates  his 
tapping  with  his  stridulous  call,  and  the  effect  on  a cool,  autumn-like  morning  is  very 
pleasing — John  Burroughs,  in  Birds,  Bees  and  Sharp  Eyes.

THE  FLICKER  OR  YELLOW-HAMMER 

Teacher's  Story 


77 


Young  flickers  “ Two  is  company , 
three  is  a crowd." 

Photo  by  J.  M.  Schreck. 


The  first  time  I ever  saw  a flicker  I 
said,  “What  a wonderful  meadow- 
lark and  what  is  it  doing  on  that 
ant  hill?”  But,  another  glance 
revealed  to  me  a red  spot  on  the 
back  of  the  bird’s  neck,  and  as  soon 
as  I was  sure  that  it  was  not  a 
bloody  gash,  I knew  that  it  marked 
no  meadow-lark.  The  top  of  the 
flicker’s  head  and  its  back  are  slaty- 
gray,  which  is  much  enlivened  by 
a bright  red  band  across  the  nape 
of  the  neck.  The  tail  is  black  above 
and  yellow  tipped  with  black  below; 
the  wings  are  black,  but  have  a 
beautiful  luminous  yellow  beneath, 
which  is  very  noticeable  during 
flight.  There  is  a locket  adorning 
the  breast  which  is  a thin,  black 
crescent,  much  narrower  than  that 
of  the  meadow-lark.  Below  the 
locket,  the  breast  is  yellowish  white 
thickly  marked  with  circular,  black  spots.  The  throat  and  sides  of  the 
head  are  pinkish  brown,  and  the  male  has  a black  mustache  extending 
backward  from  the  beak  with  a very  fashionable  droop.  Naturally 
enough  the  female,  although  she  resembles  her  spouse,  lacks  his  mus- 
tache. The  beak  is  long,  strong,  somewhat  curved  and  dark  colored. 
This  bird  is  distinctly  larger  than  the  robin.  The  white  patch  on  the 
rump  shows  little  or  none  when  the  bird  is  at  rest,  for  this  white  mark  is 
a “color  call,”  it  being  a rear  signal  by  means  of  which  the  flock  of 
migrating  birds  are  able  to  keep  together  in  the  night.  The  yellow- 
hammer’s  flight  is  wave-like  and  jerky  and  quite  different  from  that 
of  the  meadow-lark;  nor  does  it  stay  so  constantly  in  the  meadows 
but  often  frequents  woods  and  orchards. 

The  flicker  has  many  names,  such  as  golden-winged  woodpecker, 
yellow-hammer,  high-hole,  yarup,  wake-up,  clape  and  many  others.  It 
earned  the  name  of  high-hole  because  of  its  habit  of  excavating  its  nest 
high  up  in  trees,  usually  between  ten  and  twenty-five  feet  from  the 
ground.  It  especially  loves  an  old  apple  tree  as  a site  for  a nest,  and 
most  of  our  large  old  orchards  can  boast  of  a pair  of  these  handsome  birds 
during  the  nesting  season  of  May  and  June.  The  flicker  is  not  above 
renting  any  house  he  finds  vacant,  excavated  by  some  other  birds  last 
year.  He  earned  his  name  of  yarup  or  wake-up  from  his  spring  song, 
which  is  a rollicking,  jolly  “wick-a,  wick-a,  wick-a-wick”  a song  com- 
monly heard  the  last  of  March  or  early  April.  The  chief  food  of  the  flicker 
is  ants,  although  it  also  eats  beetles,  flies  and  wild  fruit,  but  does  little  or 
no  damage  to  planted  crops.  So  long  has  it  fed  upon  ants,  that  its  tongue 
has  become  modified,  like  that  of  the  ant-eater;  it  is  covered  with  a 
sticky  substance;  and  when  it  is  thrust  into  an  ant  hill,  all  of  the  little 


y8  Handbook  of  Nature-Study 

citizens,  disturbed  in  their  communal  labors,  at  once  bravely  attack  the 
intruder  and  become  glued  fast  tc  it,  and  are  thus  withdrawn  and  trans- 
ferred to  the  capacious  stomach  of  the  bird.  It  has  been  known  to  eat 
three  thousand  ants  at  a single  meal. 

Those  who  have  observed  the  flicker  during  the  courting  season  declare 
him  to  be  the  most  silly  and  vain  of  all  bird  wooers.  Mr.  Baskett  says: 
“When  he  wishes  to  charm  his  sweetheart  he  mounts  a small  twig  near 
her,  and  lifts  his  wings,  spreads  his  tail,  and  begins  to  nod  right  and  left  as 
he  exhibits  his  mustache  to  his  charmer.  He  sets  his  jet  locket  first  on 
one  side  of  the  twig  and  then  on  the  other.  He  may  even  go  so  far  as  to 
turn  his  head  half  around  to  show  her  the  pretty  spot  on  his  back  hair. 
In  doing  all  this  he  performs  the  most  ludicrous  antics  and  has  the  silliest 
expression  of  face  and  voice  as  if  in  losing  his  heart,  as  some  one  phrases 
it,  he  had  lost  his  head  also.” 

The  nest  hole  is  quite  deep  and  the  white  eggs  are  from  four  to  ten  in 
number.  The  feeding  of  the  young  flickers  is  a painful  process  to  watch. 
The  parent  takes  the  food  into  its  own  stomach  and  partially  digests  it, 
then  thrusting  its  own  bill  down  the  throat  of  the  young  one  it  pumps  the 
soft  food  into  it  “kerchug,  kerchug,”  until  it  seems  as  if  the  young  one 
must  be  shaken  to  its  foundations.  The  young  flickers  as  soon  as  they 
leave  the  nest  climb  around  freely  on  the  home  tree  in  a delightful,  playful 
manner.

Leading  thought — The  flicker  is  a true  woodpecker  but  has  changed  its 
habits  and  spends  much  of  its  time  in  meadows  hunting  for  ants  and  other 
insects;  it  makes  its  nest  in  trees,  like  its  relatives.  It  can  be  distin- 
guished from  the  meadow-lark  by  the  white  patch  above  the  tail  which 
shows  during  flight. 

Methods — This  is  one  of  the  most  important  of  birds  of  the  meadow 
and  the  work  may  be  done  in  September  when  there  are  plenty  of  young 
flickers,  which  have  not  learned  to  be  wary.  The  observations  may  be 
made  in  the  field,  a few  questions  given  at  a time. 

Observations — i . Where  do  you  find  the  flicker  in  the  summer  and 
early  autumn?  How  can  you  tell  it  from  the  meadow-lark  in  color  and 
in  flight  ? 

2.  What  is  it  doing  in  the  meadows?  How  does  it  manage  to  trap 
ants? 

3.  What  is  the  size  of  the  flicker  as  compared  to  the  robin  ? What 
is  its  general  color  as  compared  to  the  meadow-lark? 

4.  Describe  the  colors  of  the  flicker  as  follows : Top  and  sides  of  the 

head,  back  of  the  neck,  lower  back,  tail,  wings,  throat  and  breast.  The 
color  and  shape  of  the  beak.  Is  there  a difference  in  markings  between 
the  males  and  females  ? 

5.  Does  the  patch  of  white  above  the  tail  show,  except  when  the 
bird  is  flying?  Of  wdiat  use  is  this  to  the  bird? 

6.  What  is  the  flicker’s  note?  At  what  time  of  spring  do  you  hear  it 
first? 

7.  Where  does  the  flicker  build  its  nest  and  how?  What  is  the 
color  of  the  eggs  ? How  many  are  there  ? 

8.  How  does  it  feed  its  young?  . How  do  the  young  flickers  act? 

9.  How  many  names  do  you  know  for  the  flicker?

The  high-hole  appears  to  drum  more  promiscuously  than  does  the  downy.  He 
utters  his  long,  loud  spring  call,  whick-whick-whick,  and  then  begins  to  rap  with  his 
beak  upon  his  perch  before  the  last  note  has  reached  your  ear.  I have  seen  him  drum 
sitting  upon  the  ridge  of  the  barn.  The  log-cock,  or  pileated  woodpecker,  the  largest 
and  wildest  of  our  Northern  species,  I have  never  heard  drum.  His  blows  should  wake 
the  echoes. 

When  the  woodpecker  is  searching  for  food,  or  laying  siege  to  some  hidden  grub, 
the  sound  of  his  hammering  is  dead  or  muffled,  and  is  heard  but  a few  yards.  It  is 
only  upon  dry,  seasoned  timber,  freed  of  its  bark,  that  he  beats  his  reveille  to  spring  and 
woos  his  mate. — John  Burroughs,  in  Birds,  Bees  and  Sharp  Eyes.

THE  MEADOW-LARK 
Teacher's  Story 

The  first  intimation  we  have  in  early  spring,  that 
the  meadow-lark  is  again  with  us,  comes  to  us 
through  his  soft,  sweet,  sad  note  which  Van  Dyke 
describes  so  graphically  when  he  says  it,  “leaks 
^ slowly  upward  from  the  ground.”  One  wonders 

how  a bird  can  express  happiness  in  these  melan- 
choly, sweet,  slurred  notes  and  yet  undoubtedly  it 
is  a song  expressing  joy,  the  joy  of  returning  home, 
the  happiness  of  love  and  of  nest  building.  But 
after  one  has  spent  a winter  in  the  Gulf  States,  and 
has  witnessed  the  slaughter  there  of  this  most 
valuable  bird;  and  after  the  northern  stomach  and 
heart  have  turned  sick  at  the  sight  of  breasts  once  so  full  of  song  done 
brown  on  the  luncheon  table,  one  no  longer  wonders  that  the  meadow- 
lark’s song  of  joy  is  fraught  with  sadness.  There  should  be  national  laws 
to  protect  the  birds  that  are  of  value  to  one  part  of  the  United  States  from 
being  slaughtered  in  their  winter  haunts,  unless  they  are  there  a nuisance 
and  injurious  to  crops,  which  is  not  the  case  with  the  meadow-lark. 

The  meadow-lark,  as  is  indicated  by  its  name,  is  a bird  of  the  meadow. 
It  is  often  confused  with  another  bird  of  the  meadow  which  has  very 
different  habits,  the  flicker.  The  two  are  approximately  of  the  same  size 
and  color  and  each  has  a black  crescent  or  locket  on  the  breast  and  each 
shows  the  “white  feather”  during  flight.  The  latter  is  the  chief  dis- 
tinguishing character;  the  outer  tail  feathers  of  the  meadow-lark  are 
white,  while  the  tail  feathers  of  the  flicker  are  not  white  at  all,  but  it  has 
a single  patch  of  white  on  the  rump.  The  flight  of  the  two  is  quite 
different.  The  lark  lifts  itself  by  several  sharp  movements  and  then 
soars  smoothly  over  the  course,  while  the  flicker  makes  a continuous  up 
and  down,  wave-like  flight.  The  songs  of  the  two  would  surely  never  be 
confused,  for  the  meadow-lark  is  among  our  sweetest  singers,  to  which 
class  the  flicker  with  his  “flick  a flick”  hardly  belongs. 

The  colors  of  the  meadow-lark  are  most  harmonious  shades  of  brown 
and  yellow,  well  set  off  by  the  black  locket  on  its  breast.  Its  wings  are 
light  brown,  each  feather  being  streaked  with  black  and  brown;  the  line 
above  the  eye  is  yellow,  bordered  with  black  above  and  below;  a buff  line 
extends  from  the  beak  backward  over  the  crown.  The  wings  are  light 
brown  and  have  a mere  suggestion  of  white  bars;  portions  of  the  outer 
feathers  on  each  side  of  the  tail  are  white,  but  this  white  does  not  show 
except  during  flight.  The  sides  of  the  throat  are  greenish,  the  middle 
part  and  breast  are  lemon-yellow,  with  the  large,  black  crescent  just  below 
the  throat.  The  beak  is  long,  strong  and  black,  and  the  meadow-lark  is 
decidedly  a low-browed  bird,  the  forehead  being  only  slightly  higher  than 
the  upper  part  of  the  beak.  It  is  a little  larger  than  the  robin  which  it 
rivals  in  plumpness. 

The  meadow-lark  has  a particular  liking  for  meadows  which  border 
streams.  It  sings  when  on  the  ground,  on  the  bush  or  fence  and  while  on 
the  wing ; and  it  sings  during  the  entire  period  of  its  northern  stay,  from 
April  to  November,  except  while  it  is  moulting  in  late  summer.  Mr. 
Mathews,  who  is  an  eminent  authority  on  bird  songs,  says  that  the 


Bird  Study 


81 


meadow-larks  of  New  York  have  a different  song  from  those  of  Vermont 
or  Nantucket,  although  the  music  has  always  the  same  general  character- 
istics. The  western  species  has  a longer  and  more  complex  song  than 
ours  of  the  East.  It  is  one  of  the  few  California  birds  that  is  a genuine 
joy  to  the  eastern  visitor;  during  February  and  March  its  heavenly 
music  isas  pervasive  as  the  California  sunshine. 


The  meadow-lark. 
Drawing  by  L.  A.  Fuertes. 


The  nest  is  built  in  a depression  in  the  ground  near  a tuft  of  grass ; it  is 
constructed  of  coarse  grass  and  sticks  and  is  lined  with  finer  grass ; there 
is  usually  a dome  of  grass  blades  woven  above  the  nest ; and  often  a long, 
covered  vestibule  leading  to  the  nest  is  made  in  a similar  fashion.  This  is 
evidently  for  protection  from  the  keen  eyes  of  hawks  and  crows.  The 
eggs  are  laid  about  the  last  of  May  and  are  usually  from  five  to  seven  in 
number;  they  are  white,  speckled  with  brown  and  purple.  The  young 
larks  are  usually  large  enough  to  be  out  of  the  way  before  haying  time  in 

July.

Handbook  of  Nature-Study 


The  food  of  the  meadow-lark  during  the  entire  year,  consists  almost 
exclusively  of  insects  which  destroy  the  grass  of  our  meadows.  It  eats 
great  quantities  of  grasshoppers,  cut  worms,  chinch  bugs,  army  worms, 
wire  worms,  weevils,  and  also  destroys  some  weed  seeds.  Each  pupil 
should  make  a diagram  in  his  note-book  showing  the  proportions  of  the 
meadow-lark’s  different  kinds  of  food.  This  may  be  copied  from  Audubon 
Leaflet  No.  3.  The  killing  of  the  meadow-lark  in  New  York  State  is  a 
punishable  offence,  as  it  should  be  in  every  state  of  the  Union.  Everyone 
who  owns  a meadow  should  use  his  influence  to  the  uttermost  to  protect 
this  valuable  bird.  It  has  been  estimated  that  the  meadow-larks  save  to 
every  township  where  hay  is  produced,  twenty-five  dollars  each  year  on 
this  crop  alone.

LESSON  XVIII 
The  Meadow-Lark 

Leading  thought — The  meadow-lark  is  of  great  value  in  delivering  the 
grass  of  our  meadows  from  insect  destroyers.  It  has  a song  which  we  all 
know;  it  can  be  identified  by  color  as  a large,  light  brown  bird  with  white 
feathers  on  each  side  of  the  tail,  and  in  flight,  by  its  quick  up  and  down 
movements  finishing  with  long,  low,  smooth  sailing. 

Method — September  and  October  are  good  months  for  observations  on 
the  flight,  song  and  appearance  of  the  meadow-lark,  and  also  for  learning 


Bird  Study 


83 


how  to  distinguish  it  from  the  flicker.  The  notes  must  be  made  by  the 
pupils  in  the  field,  and  after  they  know  the  bird  and  its  song  let  them,  if 
they  have  opportunity,  study  the  bird  books  and  bulletins,  and  prepare 
written  accounts  of  the  way  the  meadow-lark  builds  its  nest  and  of  its 
economic  value. 

Observations — 1.  Where  have  you  seen  the  meadow-lark?  Did 

you  ever  see  it  in  the  woods  ? Describe  its  flight.  How  can  you  identify 
it  by  color  when  it  is  flying?  How  do  its  white  patches  and  its  flight 
differ  from  those  of  the  flicker? 

2.  Try  and  imitate  the  meadow-lark’s  notes  by  song  or  whistle. 
Does  it  sing  while  on  the  ground,  or  on  a bush  or  fence,  or  during  flight? 

3.  Note  the  day  when  you  hear  its  last  song  in  the  fall  and  also  its 
first  song  in  the  spring.  Does  it  sing  during  August  and  September? 
Why?  Where  does  it  spend  the  winter?  On  what  does  it  feed  while  in 
the  South?  How  are.  our  meadow-larks  treated  when  on  their  southern 
sojourn? 

4.  Is  the  meadow-lark  larger  or  smaller  than  the  robin  ? Describe 

from  your  own  observation,  as  far  as  possible,  the  colors  of  the  meadow- 
lark as  follows:  Top  of  head;  line  above  the  eye;  back;  wings;  tail; 

throat;  breast;  locket;  color  and  shape  of  beak.  Make  a sketch  of  your 
own  or  a copy  from  Louis  Fuertes’  excellent  picture  of  the  meadow-lark  in 
the  Audubon  Leaflet,  and  color  it  accurately. 

5.  When  is  the  nest  built;  where  is  it  placed;  of  what  material  is  it 
built  ? How  is  it  protected  from  sight  from  above  ? Why  this  protection, 
How  many  eggs?  What  are  their  colors  and  markings? 

6.  What  is  the  food  of  the  meadow-lark?  Copy  the  diagram  from 
the  Audubon  leaflet,  showing  the  proportions  of  the  different  kinds  of 
insects  which  it  destroys.  Why  should  the  farmers  of  the  South  also 
protect  the  meadow-lark  by  law?

Sweet,  sweet,  sweet!  O happy  that  I am! 

(. Listen  to  the  meadow-larks,  across  the  fields  that  sing!) 
Sweet,  sweet,  sweet!  O subtle  breath  of  balm, 

O winds  that  blow,  O buds  that  grow,  O rapture  of  the  spring! 

Sweet,  sweet,  sweet!  O happy  world  that  is! 

Dear  heart,  I hear  across  the  fields  my  mateling  pipe  and  call. 
Sweet,  sweet,  sweet!  O world  so  full  of  bliss. 

For  life  is  love,  the  world  is  love , and  love  is  over  all!

Teacher's  Story 


So  dainty  in  plumage  and  hue, 

A study  in  grey  and  in  brown, 

How  little,  hoiv  little  we  knew 

The  pest  he  would  prove  to  the  town! 

From  dawn  until  daylight  grows  dim, 

Perpetual  chatter  and  scold. 

No  winter  migration  for  him. 

Not  even  afraid  of  the  cold! 

Scarce  a song-bird  he  fails  to  molest, 

Belligerent,  meddlesome  thing! 

Wherever  he  goes  as  a guest 
He  is  sure  to  remain  as  a King. 

— Mary  Isabella  Forsyth. 

The  English  sparrow,  like  the  poor  and  the  house-fly,  is  always  with 
us;  and  since  he  is  here  to  stay,  let  us  make  him  useful  if  we  can  devise 
any  means  of  doing  so.  There  is  no  bird  that  gives  the  pupils  a more 
difficult  exercise  in  describing  colors  and  markings  than  does  he;  and  his 
wife  is  almost  equally  difficult.  I have  known  fairly  skilled  ornithologists 
to  be  misled  by  some  variation  in  color  of  the  hen  sparrow,  and  it  is  safe 
to  assert  that  the  majority  of  people  “do  not  know  her  from  Adam.” 
The  male  has  the  top  of  the  head  gray  with  a patch  of  reddish  brown  on 
either  side ; the  middle  of  the  throat  and  upper  breast  is  black ; the  sides 
of  the  throat  white ; the  lower  breast  and  under  parts  grayish  white ; the 


Bird  Study 


85 


back  is  brown  streaked  with  black;  the  tail  is  brown,  rather  short,  and  not 
notched  at  the  tip;  the  wings  are  brown  with  two  white  bars  and  a jaunty 
dash  of  reddish  brown.  The  female  has  the  head  grayish  brown,  the 
breast,  throat  and  under  parts  grayish  white;  the  back  is  brown  streaked 
with  black  and  dirty  yellow,  and  she  is,  on  the  whole,  a “washed  out” 
looking  lady  bird.  The  differences  in  Color  and  size  between  the  English 
sparrow  and  the  chippy  are  quite  noticeable,  as  the  chippy  is  an  inch 
shorter  and  far  more  slender  in  appearance,  and  is  especially  marked  by 
the  reddish  brown  crown. 

When  feeding,  the  English  sparrows  are  aggressive,  and  their  lack  of 
table  manners  make  them  the  “goops”  among  all  birds;  in  the  winter 
they  settle  in  noisy  flocks  on  the  street  to  pick  up  the  grain  undigested  by 
the  horses,  or  in  barnyards  where  the  grain  has  been  scattered  by  the 
cattle.  They  only  eat  weed  seeds  when  other  food  fails  them  in  the 
winter,  for  they  are  a civilized  bird  even  if  they  do  not  act  so,  and  they 
much  prefer  the  cultivated  grains.  It  is  only  during  the  nesting  season 
that  they  destroy  insects  to  any  extent ; over  one-half  the  food  of  nestlings 
is  insects,  such  as,  weevils,  grasshoppers,  cutworms,  etc.;  but  this  good 
work  is  largely  offset  by  the  fact  that  these  same  nestlings  will  soon  give 
their  grown-up  energies  to  attacking  grain  fields,  taking  the  seed  after 
sowing,  later  the  new  grain  in  the  milk,  and  later  still  the  ripened  grain  in 
the  sheaf.  Wheat,  oats,  rye,  barley,  corn,  sorghum  and  rice  are  thus 
attacked.  Once  I saw  on  the  upper  Nile  a native  boat  loaded  with  millet 
which  was  attacked  by  thousands  of  sparrows;  when  driven  off  by  the 
sailors  they  would  perch  on  the  rigging,  like  flies,  and  as  soon  as  the  men 
turned  their  backs  they  would  drop  like  bullets  to  the  deck  and  gobble 
the  grain  before  they  were  again  driven  off.  English  sparrows  also 
destroy  for  us  the  buds  and  blossoms  of  fruit  trees  and  often  attack  the 
ripening  fruit. 

The  introduction  of  the  English  sparrow  into  America  is  one  of  the 
greatest  arguments  possible  in  favor  of  nature-study;  for,  ignorance  of 
nature-study  methods  in  this  single  instance,  costs  the  United  States 
millions  of  dollars  every  year.  The  English  sparrow  is  the  European 
house  sparrow  and  people  had  a theory  that  it  was  an  insect  eater,  but 
never  took  the  pains  to  ascertain  if  this  theory  were  a fact.  About  1850, 
some  people  with  more  zeal  than  wisdom  introduced  these  birds  into  New 
York,  and  for  twenty  years  afterwards  there  were  other  importations  of 
the  sparrows.  In  twenty  years  more,  people  discovered  that  they  had 
taken  great  pains  to  establish  in  our  country  one  of  the  worst  nuisances 
in  all  Europe.  In  addition  to  all  the  direct  damage  which  the  English 
sparrows  do,  they  are  so  quarrelsome  that  they  have  driven  away  many 
of  our  native  beneficial  birds  from  our  premises,  and  now  vociferously 
acclaim  their  presence  in  places  which  were  once  the  haunts  of  birds  with 
sweet  songs.  After  they  drive  off  the  other  birds  they  quarrel  among 
themselves,  and  there  is  no  rest  for  tired  ears  in  their  vicinity . There  are 
various  noises  made  by  these  birds  which  we  can  understand  if  we  are 
willing  to  take  the  pains:  The  harassing  chirping  is  their  song;  they 

squall  when  frightened  and  peep  plaintively  when  lonesome,  and  make  a 
disagreeable  racket  when  fighting. 

But  to  “give  the  devil  his  due”  we  must  admit  that  the  house  sparrow 
is  as  clever  as  it  is  obnoxious,  and  its  success  is  doubtless  partly  due  to  its 
superior  cleverness  and  keenness.  It  is  quick  to  take  a hint,  if  sufficiently 


86 


Handbook  of  Nature-Study 


pointed ; firing  a shotgun  twice  into  a flock  of  these  birds  has  driven  them 
from  our  premises ; and  tearing  down  their  nests  assiduously  for  a month 
seems  to  convey  to  them  the  idea  that  they  are  not  welcome.  Another 
instance  of  their  cleverness  1 witnessed  one  day ; I was  watching  a robin, 
worn  and  nervous  with  her  second  brood,  fervently  hunting  earthworms 
in  the  lawn  to  fill  the  gaping  mouths  in  the  nest  in  the  Virginia  creeper 
shading  the  piazza.  She  finally  pulled  up  a large,  pink  worm  and  a hen 
sparrow  flew  at  her  viciously;  the  robin  dropped  the  worm  to  protect 
herself,  and  the  sparrow  snatched  it  and  carried  it  off  triumphantly  to  the 
grape  arbor  where  she  had  a nest  of  her  own  full  of  gaping  mouths.  She 
soon  came  back,  and  at  a safe  distance  watched  the  robin  pull  out  another 
worm,  and  by  the  same  tactics  again  gained  the  squirming  prize.  Three 
times  was  this  repeated  in  an  hour,  and  then  the  robin,  discouraged,  flew 
up  into  a Norway  spruce  and  in  a monologue  of  sullen  duckings  tried  to 
reason  out  what  had  happened. 

The  English  sparrow’s  nest  is  quite  in  keeping  with  the  bird’s  other 
qualities;  it  is  usually  built  in  a hole  or  box  or  in  some  protected  comer 
beneath  the  eaves;  it  is  also  often  built  in  vines  on  buildings  and  occa- 
sionally in  trees.  It  is  a good  example  of  “fuss  and  feathers”;  coarse 
straw,  or  any  other  kind  of  material,  and  feathers  of  hens  or  of  other 
birds,  mixed  together  without  fashion  or  form,  constitute  the  nest.  In 
these  sprawling  nests  the  whitish,  brown  or  gray-flecked  eggs  are  laid 
and  the  young  reared;  and  so  far  as  I can  ascertain,  no  one  has  ever 
counted  the  number  of  broods  reared  in  one  season.  The  nesting  begins 
almost  as  soon  as  the  snow  is  off  the  ground  and  lasts  until  late  fall. 

During  the  winter,  the  sparrows  gather  in  flocks  in  villages  and  cities, 
but  in  the  spring  they  scatter  out  through  the  country  where  they  can 
find  more  grain.  The  only  place  where  this  bird  is  welcome  is  possibly 
in  the  heart  of  a great  city,  where  no  other  bird  could  pick  up  a liveli- 
hood. It  is  a true  cosmopolite  and  is  the  first  bird  to  greet  the  traveler 
in  Europe  or  northern  Africa.  • These  sparrows  will  not  build  in  boxes 
suspended  by  a wire ; and  they  do  not  like  a box  where  there  is  no  resting 
place  in  front  of  the  door  leading  to  the  nest. 

After  the  pupils  have  made  observations  upon  the  habits  of  the  house 
sparrow,  they  may  find,  in  the  following  books  and  bulletins,  facts  which 
will  teach  further  the  economic  importance  of  this  bird : Birds  in  Their

LESSON  XIX 
The  English  Sparrow 

Leading  thought — The  English  sparrow  was  introduced  into  America 
by  people  who  knew  nothing  of  its  habits.  It  has  finally  over-run  our 
whole  country  and,  to  a great  extent,  has  driven  out,  from  towns  and 
villages  our  useful  American  song  birds  and  it  should  be  discouraged  and 
not  allowed  to  nest  around  our  houses  and  grounds.  As  a sparrow  it  has 
interesting  habits  which  we  should  observe. 

Methods — Let  the  pupils  make  their  observations  in  the  street  or 
wherever  they  find  the  birds.  The  greatest  value  of  this  lesson  is  to  teach 


Bird  Study 


87 


the  pupils  to  observe  the  coloring  and  markings  of  a bird  accurately  and 
describe  them  clearly.  This  is  the  best  of  training  for  later  work  with 
the  wild  birds. 

Observations — 1.  How  many  kinds  of  birds  do  you  find  in  a flock  of 
English  sparrows  ? 

2 . The  ones  with  the  black  cravat  are  naturally  the  men  of  the 
family,  while  their  sisters,  wives  and  mothers  are  less  ornamented.

THE  CHIPPING  SPARROW 

Teacher's  Story 

HIS  midget  lives  in  our  midst,  and  yet,  not  among  all 
bird  kind,  is  there  one  which  so  ignores  us  as  does  the 
chippy.  It  builds  its  nest  about  our  houses,  it  hunts 
for  food  all  over  our  premises,  it  sings  like  a tuneful 
grasshopper  in  our  ears,  it  brings  up  its  young  to  dis- 
regard us,  and  every  hour  of  the  day  it  “tsip-tsips”  us 
to  scorn.  And,  although  it  has  well  earned  the  name 
of  “doorstep  sparrow,”  since  it  frugally  gathers  the 
crumbs  about  our  kitchen  doors,  yet  it  rarely  be- 
comes tame  or  can  be  induced  to  eat  from  the  hand,  unless  it  is  trained 
so  to  do  as  a nestling. 

Its  cinnamon-brown  cap  and  tiny  black  forehead,  the  gray  streak  over 
the  eye  and  the  black  through  it,  the  gray  cheeks  and  the  pale  gray, 
unspotted  breast  distinguish  it  from  the  other  sparrows,  although  its 
brown  back  streaked  with  darker,  and  brown  wings  and  blackish  tail 
have  a very  sparrowish  look;  the  two  whitish  wing  bars  are  not  striking; 
it  has  a bill  fitted  for  shelling  seeds,  a characteristic  of  all  the  sparrows. 
Despite  its  seed-eating  bill,  the  chippy’s  food  is  thirty-eight  per-cent 
insects,  and  everyone  should  read  what  Mr.  Forbush  says  about  the  good 
work  this  little  bird  does  in  our  gardens  and  to  our  trees.  It  takes  in 
large  numbers  cabbage  caterpillars,  the  pea  louse,  the  beet  leaf-miners, 
leaf  hoppers,  grasshoppers,  cutworms,  and  does  its  best  to  annihilate  the 
caterpillars  of  the  terrible  gypsy  and  browntail  moths.  In  fact,  it  works 
for  our  benefit  even  in  its  vegetable  food,  as  this  consists  largely  of  the 
seeds  of  weeds  and  undesirable  grasses.  It  will  often  fly  up  from  its 
perch  after  flies  or  moths,  like  a flycatcher;  and  the  next  time  we  note  it, 
it  will  be  hopping  around  hunting  for  the  crumbs  we  have  scattered  for  it 
on  the  piazza  floor.  The  song  of  the  chippy  is  more  interesting  to  it  than 
to  us;  it  is  a continuous  performance  of  high,  shrill,  rapid  notes,  all  alike 
so  far  as  I can  detect ; when  it  utters  many  of  these  in  rapid  succession  it 
is  singing,  but  when  it  gives  them  singly  they  are  call  notes  or  mere 
conversation. 

One  peculiarity  of  the  nest  has  given  this  sparrow  the  common  name 
of  hair-bird,  for  the  lining  is  almost  always  of  long,  coarse  hair,  usually 
treasure  trove  from  the  tails  of  horses  or  cattle  switched  off  against  boards, 
burs  or  other  obstacles.  Of  the  many  nests  I have  examined,  black 
horsehair  was  the  usual  lining;  but  two  nests  in  our  yard  show  the 
chippy  to  be  a resourceful  bird ; evidently  the  hair  market  was  exhausted 
and  the  soft,  dead  needles  of  the  white  pine  were  used  instead  and  made 
a most  satisfactory  lining.  The  nest  is  tiny  and  shallow;  the  outside  is 
of  fine  grass  or  rootlets  carefully  but  not  closely  woven  together;  it  is 
placed  in  vine  or  tree,  usually  not  more  than  ten  or  fifteen  feet  from  the 
ground;  a vine  of  a piazza  is  a favorite  nesting  site.  Once  a bold  pair 
built  directly  above  the  entrance  to  our  front  door  and  mingled  cheer- 
fully with  other  visitors.  Usually,  however,  the  nest  is  so  hidden  that  it 
is  not  discovered  until  after  the  leaves  have  fallen.  The  eggs  are  light 
blue  tinged  with  green,  with  fine,  purplish  brown  specks  or  markings 
scrawled  about  the  larger  end.

The  chippy  comes  to  us 
in  April  and  usually  raises 
two  broods  of  from  three  to 
five  “piggish”  youngsters, 
which  even  after  they  are  fully 
grown  follow  pertinaciously 
their  tired  and  “frazzled  out” 
parents  and  beg  to  be  fed; 
the  chippy  parents  evidently 
have  no  idea  of  discipline 
but  indulge  their  teasing 
progeny  until  our  patience,  at  The  chipping  sparrow . 

least,  is  exhausted.  The 

young  differ  from  the  parents  in  having  streaked  breasts  and  lacking  the 
reddish  crown.  In  the  fall  the  chippy  parents  lose  their  red-brown 
caps  and  have  streaked  ones  instead;  and  then  they  fare  forth  in  flocks 
for  a seed-harvest  in  the  fields.  Thereafter  our  chippy  is  a stranger  to 
us;  we  do  not  know  it  in  its  new  garb,  and  it  dodges  into  the  bushes  as 
we  pass,  as  if  it  had  not  tested  our  harmlessness  on  our  own  door-stone.

LESSON  XX 

Leading  thought — The  chipping  sparrow  is  a cheerful  and  useful  little 
neighbor.  It  builds  a nest,  lined  with  horsehair,  in  the  shrubbery  and 
vines  about  our  homes  and  works  hard  in  ridding  our  gardens  of  insect 
pests  and  seeds  of  weeds. 

Methods — Begin  this  lesson  with  a nest  of  the  chippy,  which  is  so 
unmistakable  that  it  may  be  identified  when  found  in  the  winter.  Make 
the  study  of  this  nest  so  interesting  that  the  pupils  will  wait  anxiously 
to  watch  for  the  birds  which  made  it.  As  soon  as  the  chippies  appear, 
the  questions  should  be  asked,  a few  at  a time,  giving  the  children  several 
weeks  for  the  study. 

The  Nest 

Observations — 1.  Where  was  this  nest  found?  How  high  from  the 
ground? 

2.  Was  it  under  shelter?  How  was  it  supported? 

3.  Of  what  material  is  the  outside  of  the  nest?  How  is  it  fastened 
together?  How  do  you  suppose  the  bird  wove  this  material  together? 

4.  Of  what  material  is  the  lining?  Why  is  the  bird  that  built  this 
nest  called  the  “hair  bird?”  From  what  animal  do  you  think  the  lining 
of  the  nest  came?  How  do  you  suppose  the  bird  got  it? 

5.  Do  you  think  the  nest  was  well  hidden  when  the  leaves  were  about 
it?  Measure  the  nest  across  and  also  its  depth;  do  you  think  the  bird 
that  made  it  is  as  large  as  the  English  sparrow? 

The  Bird 

6.  How  can  you  tell  the  chippy  from  the  English  sparrow? 

7.  Describe  in  your  note-book  or  orally  the  colors  of  the  chippy  as 

follows:  beak,  forehead,  crown,  marks  above  and  through  the  eyes, 


90  Handbook  of  N ature-Study 

cheeks,  throat,  breast,  wings  and  tail.  Note  if  the  wings  have  whitish 
bars  and  how  many. 

8.  Describe  the  shape  of  the  beak  as  compared  with  that  of  the  robin. 
What  is  this  shaped  bill  meant  for? 

9.  What  is  the  food  of  the  chippy?  Why  has  it  been  called  the 
doorstep-sparrow  ? 

10.  Note  if  the  chippy  catches  flies  or  moths  on  the  wing  like  the 
phoebe-bird. 

11.  Why  should  we  protect  the  chippy  and  try  to  induce  it  to  live 
near  our  gardens  ? 

12.  Does  it  run  or  hop  when  seeking  food  on  the  ground? 

13.  How  early  in  the  season  does  the  chippy  appear  and  where  does  it 
spend  the  winter? 

14.  Can  you  describe  the  chippy’s  song?  How  do  you  think  it  won 
the  name  of  chipping  sparrow? 

15.  If  you  have  the  luck  to  find  a pair  of  chippies  nesting,  keep  a 

diary  of  your  observations  in  your  note-book  covering  the  following 
points:  Do  both  parents  build  the  nest?  How  is  the  frame-work  laid? 

How  is  the  finishing  done ? The  number  and  color  of  the  eggs?  Do  both 
parents  feed  the  young?  How  do  young  chippies  act  when  they  first 
leave  the  nest  ? How  large  are  the  young  birds  before  the  parents  stop 
feeding  them?  What  are  the  differences  in  color  and  markings  between 
parents  and  young? 


THE  FIELD-SPARROW 

A bubble  of  music  floats,  the  slope  of  the  hillside  over; 

A little  wandering  sparrow’s  notes;  and  the  bloom  of  yarrow  and  clover , 

And  the  smell  of  sweet-fern  and  the  bayberry  leaf,  on  his  ripple  of  song  are  stealing, 
For  he  is  a cheerful  thief,  the  wealth  of  the  fields  revealing. 

One  syllable,  clear  and  soft  o,j  c raindrop’s  silvery  patter, 

Or  a tinkling  fairy-bell;  heard  aloft,  in  the  midst  of  the  merry  chatter 
Of  robin  and  linnet  and  wren  and  jay,  one  syllable,  oft  repeated; 

He  has  but  a word  to  say,  and  of  that  he  will  not  be  cheated. 

The  singer  I have  not  seen;  but  the  song  I arise  and  follow 
The  brown  hills  over,  the  pastures  green,  and  into  the  sunlit  hollow. 

With  a joy  that  his  life  unto  mine  has  lent,  I can  feel  my  glad  eyes  glisten, 

Though  he  hides  in  his  happy  tent,  while  I stand  outside,  and  listen. 

This  way  woutd  I also  sing,  my  dear  little  hillside  neighbor! 

A tender  carol  of  peace  to  bring  to  the  sunburnt  fields  of  labor 
Is  better  than  making  a loud  ado;  trill  on,  amid  clover  and  yarrow! 

There's  a heart-beat  echoing  you,  and  blessing  you,  blithe  little  sparrow! 

— Lucy  Larcom.

THE  SONG  SPARROW 

Teachers'  Story 

*'He  does  not  wear  a Joseph's  coat  of  many  colors,  smart  and  gay 
His  suit  is  Quaker  brown  and  gray,  with  darker  patches  at  his  throat. 

And  yet  of  all  the  well-dressed  throng,  not  one  can  sing  so  brave  a song. 

It  makes  the  pride  of  looks  appear  a vain  and  foolish  thing  to  hear 
His  “Sweet,  sweet,  sweet,  very  merry  cheer." 

A lofty  place  he  does  not  love,  he  sits  by  choice  and  well  at  ease 
In  hedges  and  in  little  trees,  that  stretch  their  slender  arms  above 
The  meadow  brook;  and  then  he  sings  till  all  the  field  with  pleasure  rings; 

And  so  he  tells  in  every  ear,  that  lowly  homes  to  heaven  are  near 
In  'Sweet,  sweet,  sweet,  very  merry  cheer.'  " 

— Henry  Van  Dyke. 

Children  should  commit  to  memory  the  poem  from  which  the  above 
stanzas  were  taken;  seldom  in  literature,  have  detailed  accurate  observa- 
tion and  poetry  been  so  happily  combined  as  in  these  verses.  The  lesson 
might  begin  in  March  when  we  are  all  listening  eagerly  for  bird  voices, 
and  the  children  should  be  asked  to  look  out  for  a little,  brown  bird  which 
sings,  “Sweet,  sweet,  sweet,  very  merry  cheer,”  or,  as  Thoreau  interprets 
it,  “Maids!  Maids!  Maids!  Hang  on  the  teakettle,  teakettle-ettle- 
ettle.”  In  early  childhood  I learned  to  distinguish  this  sparrow  by  its 
“Teakettle”  song.  Besides  this  song,  it  has  others  quite  as  sweet;  and 
when  alarmed  it  utters  a sharp  “T’chink,  t’chink.” 

The  song  sparrow  prefers  the  neighborhood  of  brooks  and  ponds  which 
are  bordered  with  bushes,  and  also  the  hedges  planted  by  nature  along 
rail  or  other  field  fences,  and  it  has  a special  liking  for  the  shrubbery  about 
gardens.  Its  movements  and  flight  are  very  characteristic;  it  usually 
sits  on  the  tip-top  of  a shrub  or  low  tree  when  it  sings,  but  when  disturbed 


92 


Handbook  of  Nature-Study 


never  rises  in  the  air  but  drops  into  a low  flight  and  plunges  into  a thicket 
with  a defiant  twitch  of  the  tail  which  says  plainly,  “find  me  if  you  can.” 

The  color  and  markings  of  this  bird  are  typical  of  the  sparrows.  The 
head  is  a warm  brown  with  a gray  streak  along  the  center  of  the  crown 
and  one  above  each  eye,  with  a dark  line  through  the  eye.  The  back  is 
brown  with  darker  streaks.  The  throat  is  white  with  a dark  spot  on 
either  side;  the  breast  is  white  spotted  with  brown  with  a large,  dark 
blotch  at  its  very  center;  this  breast  blotch  distinguishes  this  bird  from 
all  other  sparrows.  The  tail  and  wings  are  brown  and  without  buff  or 
white  bars  or  other  markings.  The  tail  is  long,  rounded  and  very  expres- 
sive of  emotions,  and  makes  the  bird  look  more  slender  than  the  English 
sparrow. 

The  nest  is  usually  placed  on  the  ground  or  in  low  bushes  not  more 
than  five  feet  from  the  ground;  it  varies  much  in  both  size  and  material; 
it  is  sometimes  constructed  of  coarse  weeds  and  grasses ; and  sometimes 
only  fine  grass  is  used.  Sometimes  it  is  lined  with  hair,  and  again, with 
fine  grass;  sometimes  it  is  deep,  but  occasionally  is  shallow.  The  eggs 
have  a whitish  ground-color  tinged  with  blue  or  green,  but  are  so  blotched 
and  marked  with  brown  that  they  are  safe  from  observation  of  enemies. 
The  nesting  season  begins  in  May,  and  there  are  usually  three  and  some- 
times four  broods;  but  so  far  as  I have  observed,  a nest  is  never  used  for 
two  consecutive  broods.  The  song  sparrow  stays  with  us  in  New  York 
State  very  late  in  the  fall,  and  a few  stay  in  sheltered  places  all  winter. 
The  quality  in  this  bird  which  endears  him  to  us  all  is  the  spirit  of  song 
which  stays  with  him ; his  sweet  trill  may  be  heard  almost  any  month  of 
the  year,  and  he  has  a charming  habit  of  singing  in  his  dreams,  if  sudden 
noise  disturbs  his  slumber. 

The  song  sparrow  is  not  only  the  dearest  of  little  neighbors,  but  it  also 
works  lustily  for  our  good  and  for  its  own  food  at  the  same  time.  It 
destroys  cutworms,  plant-lice,  caterpillars,  canker-worms,  ground  beetles, 
grasshoppers  and  flies;  in  winter  it  destroys  thousands  of  weed  seeds, 
which  otherwise  would  surely  plant  themselves  to  our  undoing.  Every 
boy  and  girl  should  take  great  pains  to  drive  away  stray  cats  and  to  teach 
the  family  puss  not  to  meddle  with  birds ; for  cats  are  the  worst  of  all  the 
song  sparrow’s  enemies,  destroying  thousands  of  its  nestlings  every  year. 


LESSON  XXI 
The  Song  Sparrow 

Leading  thought — The  beautiful  song  of  this  sparrow  is  heard  earlier  in 
the  spring  than  the  notes  of  bluebird  or  robin.  The  dark  blotch  in  the 
center  of  its  speckled  breast  distinguishes  this  sparrow  from  all  others; 
it  is  very  beneficial  and  should  be  protected  from  cats. 

Methods — All  the  observations  of  the  song  sparrow  must  be  made  in 
the  field,  and  they  are  easily  made  because  the  bird  builds  near  houses,  in 
gardens,  and  in  the  shrubbery.  Poetry  and  other  literature  about  the 
song  sparrow  should  be  given  to  the  pupils  to  read  or  to  memorize. 

Observations — i . Have  you  noticed  a little  brown  bird  singing  a very 
sweet  song  in  the  early  spring  ? Did  the  song  sound  as  if  set  to  the  words 
“Little  Maid!  Little  Maid!  Little  Maid!  Put  on  the  teakettle,  tea- 
kettle-ettle  ettle?”

2.  Where  was  this  bird  when  you  heard  him  singing?  How  high  was 
he  perched  above  the  ground?  What  other  notes  did  you  hear  him  utter? 

3.  Describe  the  colors  and  markings  of  the  song  sparrow  on  head,

5.  Where  and  of  what  material  does  the  song  sparrow  build  its  nest? 

6.  What  colors  and  markings  are  on  the  eggs?  Do  you  think  these 
colors  and  markings  are  useful  in  concealing  the  eggs  when  the  mother 
bird  leaves  the  nest?

THE  SING-AWAY  BIRD 
Have  you  ever  heard  of  the  Sing-away  bird, 

That  sings  where  the  Runaway  River 
Runs  down  with  its  rills  from  the  bald-headed  hills 
That  stand  in  the  sunshine  and  shiver ? 

“Oh,  sing!  sing-away!  sing-away!” 

How  the  pines  and  the  birches  are  stirred 
By  the  trill  of  the  Sing-away  bird! 

And  the  bald-headed  hills,  with  their  rocks  and  their  rills, 
To  the  tune  of  his  rapture  are  ringing; 

And  their  faces  grow  young,  all  the  gray  mists  among, 
While  the  forests  break  forth  into  singing. 

“Oh  sing!  sing-away!  sing-away !” 

And  the  river  runs  singing  along; 

And  the  flying  winds  catch  up  the  song. 

'T  was  a white-throated  sparrow,  that  sped  a light  arrow 
Of  song  from  his  musical  quiver, 

And  it  pierced  with  its  spell  every  valley  and  dell 
On  the  banks  of  the  Runaway  River. 

“Oh,  sing!  sing-away!  sing-away!” 

The  song  of  the  wild  singer  had 

The  sound  of  a soul  that  is  glad.— Lucy  Larcom.

The  mockingbird. 
Drawing  by  L.  A.  Fuertes. 


THE  MOCKINGBIRD 

Teacher's  Story 

Among  all  the  vocalists  in  the  bird  world,  the  mockingbird  is  unrivaled 
in  the  variety  and  richness  of  his  repertoire;  and  he  has  thus  won  his 
place  among  men,  convincing  many  ignorant  people  by  the  means  of  his 
voice  that  a bird  is  good  for  something  besides  “victuals.”  The  mocking- 
birds go  as  far  north  as  southern  New  England,  but  they  are  found  at  their 
best  in  the  Southern  States  and  in  California.  On  the  Gulf  Coast  the 
mockers  begin  singing  in  February ; in  warmer  climates  they  sing  almost 
the  year  through.  During  the  nesting  season,  the  father  mocker  is  so 
busy  with  his  cares  and  duties  during  the  day,  that  he  does  not  have  time 
to  sing  and  so  devotes  the  nights  to  serenading;  he  may  sing  almost  all 
night  long  if  there  is  moonlight,  but  even  on  dark  nights  he  gives  now 
and  then  a happy,  sleepy  song.  Not  all  mockingbirds  are  mockers; 
some  sing  their  own  song  which  is  rich  and  beautiful ; while  others  learn 
in  addition,  not  only  the  songs  of  other  birds,  but  their  call  notes  as  well. 
One  authority  noted  a mocker  which  imitated  the  songs  of  twenty 
species  of  birds  during  a ten-minute  performance.  When  singing,  the 
mocker  shows  his  relationship  to  the  brown  thrasher  by  lifting  the  head

and  depressing  and  jerking  the  tail.  A good  mocker  will  learn  a tune,  or 
parts  of  it,  if  it  is  whistled  often  enough  in  his  hearing;  he  will  also 
imitate  other  sounds  and  will  often  improve  on  a song  he  has  learned  from 
another  bird  by  introducing  frills  of  his  own;  when  learning  a song,  he 
sits  silent  and  listens  intently,  but  will  not  try  to  sing  it  until  it  is  learned. 

Although  the  mockingbirds  live  in  wild  places,  they  prefer  the  haunts 
of  men,  taking  up  their  home  sites  in  gardens  and  cultivated  grounds. 
Their  flight  is  rarely  higher  than  the  tree  tops  and  is  decidedly  jerky  in 
character  with  much  twitching  of  the  long  tail.  For  nesting  sites,  they 
choose  thickets  or  the  lower  branches  of  trees,  being  especially  fond  of 
orange  trees ; the  nest  is  usually  from  four  to  twenty  feet  from  the  ground. 
The  foundation  of  the  nest  is  made  of  sticks,  grasses  and  weed  stalks 
interlaced  and  crisscrossed;  on  these  is  built  the  nest  of  softer  materials, 
such  as,  rootlets,  horsehair,  cotton,  or  in  fact,  anything  suitable  which  is 
at  hand.  The  nest  is  often  in  plain  sight,  since  the  mocker  trusts  to  his 
strength  as  a fighter  to  protect  it.  He  will  attack  cats  with  great  ferocity 
and  vanquish  them;  he  will  kill  snakes;  often  good-sized  black  snakes 
have  been  known  to  end  thus.  The  mocker,  in  making  his  attack,  hovers 
above  his  enemy  and  strikes  it  at  the  back  of  the  head  or  neck;  he  will 
also  drive  away  birds  much  larger  than  himself. 

The  female  lays  from  four  to  six  pale  greenish  or  bluish  eggs 
blotched  with  brown  and  which  hatch  in  about  two  weeks;  then 
comes  a period  of  hard  work  for  the  parents,  as  both  are  indefatigable 
in  catching  insects  to  feed  the  young.  The  mocker,  by  the  way,  is  a 
funny  sight  when  he  is  chasing  a beetle  on  the  ground,  lifting  his  wings 
in  . a pugnacious  fashion.  The  mockers  often  raise  three  broods  a 
season ; the  young  birds  have  spotted  breasts,  showing  their  relationship 
to  the  thrasher. 

As  a wooer,  the  mocker  is  a bird  of  much  ceremony  and  dances  into  his 
lady’s  graces.  Mrs.  F.  W.  Rowe,  in  describing  this,  says  that  the  birds 
stand  facing  each  other  with  heads  and  tails  erect  and  wings  drooping; 
“then  the  dance  would  begin,  and  this  consisted  of  the  two  hopping 
sideways  in  the  same  direction  and  in  rather  a straight  line  a few  inches  at 
a time,  always  keeping  directly  opposite  each  other  and  about  the  same 
di  stance  apart.  They  would  chassez  this  way  four  or  five  feet,  then  go 
back  over  the  same  line  in  the  same  manner.’’  Mrs.  Rowe  also  observed 
that  the  male  mockers  have  hunting  preserves  of  their  own,  not  allowing 
any  other  males  of  their  species  in  these  precincts.  The  boundary  was 
sustained  by  tactics  of  both  offense  and  defense ; but  certain  other  species 
of  birds  were  allowed  to  trespass  without  reproof. 

Maurice  Thompson  describes  in  a delightful  manner  the  “mounting” 
and  “dropping”  songs  of  the  mocker  which  occur  during  the  wooing  season. 
The  singer  flits  up  from  branch  to  branch  of  a tree,  singing  as  he  goes,  and 
finally  on  the  topmost  bough  gives  his  song  of  triumph  to  the  world ; then, 
reversing  the  process,  he  falls  backward  from  spray  to  spray,  as  if  drunk 
with  the  ecstasy  of  his  own  song,  which  is  an  exquisitely  soft  “gurgling 
series  of  notes,  liquid  and  sweet,  that  seem  to  express  utter  rapture.” 

The  mockingbirds  have  the  same  colors  in  both  sexes;  the  head  is 
black,  the  back  is  ashy-gray ; the  tail  and  wings  are  so  dark  brown  that 
they  look  black;  the  tail  is  very  long  and  has  the  outer  tail  feathers 
entirely  white  and  the  two  next  inner  ones  ere  white  for  more  than  half 
their  length;  the  wings  have  a strikingly  broad,  white  bar.  which  is  very

noticeable  when  the  bird  is  flying.  The  under  parts  and  breast  are 
grayish  white ; the  beak  and  legs  are  blackish.  The  food  of  the  mocking- 
birds is  about  half  insects  and  half  fruit.  They  live  largely  on  the  berries 
of  the  red  cedar,  myrtle  and  holly,  and  we  must  confess  are  often  too 
devoted  to  the  fruits  in  our  orchards  and  gardens;  but  let  us  put  down  to 
their  credit  that  they  do  their  best  to  exterminate  the  cotton  boll  cater- 
pillars and  moths,  and  also  many  other  insects  injurious  to  crops. 

The  mocker  is  full  of  tricks  and  is  distinctly  a bird  of  humor.  He  will 
frighten  other  birds  by  screaming  like  a hawk  and  then  seem  to  chuckle 
over  the  joke. 

Sidney  Lanier  describes  him  well. 

Whate’er  birds  did  or  dreamed,  this  bird  could  say. 

Then  down  he  shot,  bounced  airily  along 

The  sward,  twitched  in  a grasshopper,  made  song 

Midflight,  perched,  prinked,  and  to  his  art  again. 

LESSON  XXII 
The  Mocking  Bird 

Leading  thought — The  mockingbird  is  the  only  one  of  our  common 
birds  that  sings  regularly  at  night.  It  imitates  the  songs  of  other  birds 
and  has  also  a beautiful  song  of  its  own.  When  feeding  their  nestlings, 
the  mockers  do  us  great  service  by  destroying  insect  pests. 

Method — Studies  of  this  bird  are  best  made  individually  by  the  pupils 
through  watching  the  mockers  which  haunt  the  houses  and  shrubbery. 
If  there  are  mockingbirds  near  the  schoolhouse  the  work  can  be  done  in 
the  most  ideal  way  by  keeping  records  in  the  school  of  all  the  observations 
made  by  the  pupils,  thus  bringing  out  an  interesting  mockingbird  story. 
The  experiment  in  teaching  songs  to  the  birds  may  best  be  made  with  pet 
mockers. 

Observations — i.  At  what  months  of  the  year  and  for  how  many 
months  does  the  mockingbird  sing  in  this  locality? 

2.  Does  he  sing  only  on  moonlight  nights?  Does  he  sing  all  night? 

3.  Can  you  distinguish  the  true  mockingbird  song  from  the  songs 
which  he  has  learned  from  other  birds  ? Describe  the  actions  of  a mocker 
when  he  is  singing. 

4.  How  many  songs  of  other  birds  have  you  heard  a mocker  give  and 
what  are  the  names  of  these  birds? 

5.  Have  you  ever  taught  a mocker  a tune  by  whistling  it  in  his 
presence?  If  so,  tell  how  long  before  he  learned  it  and  how  he  acted 
while  learning. 

Describe  the  flight  of  the  mockingbirds.  Do  they  fly  high  in  the  air 
like  crows? 

7.  Do  these  birds  like  best  to  live  in  wild  places  or  about  houses  and 
gardens  ? 

8.  Where  do  they  choose  sites  for  their  nests?  Do  they  make  an 
effort  to  hide  the  nest?  If  not,  why? 

9.  Of  what  material  is  the  nest  made?  How  is  it  lined?  How  far 
from  the  ground  is  it  placed? 

10.  What  are  the  colors  of  the  eggs?  How  many  are  usually  laid? 
How  long  before  they  hatch?

11.  Give  instances  of  the  parents’  devotion  to  the  young  birds. 

12.  Have  you  seen  two  mockingbirds  dancing  before  each  other  just 
before  the  nesting  season  ? 

13.  In  the  spring  have  you  heard  a mocker  sing  while  mounting  from 
the  lower  to  the  upper  branches  of  a tree  and  then  after  pouring  forth  his 
best  song  fall  backward  with  a sweet,  gurgling  song  as  if  intoxicated  with 
his  music  ? 

14.  How  many  broods  does  a pair  of  mockers  raise  during  one  season  ? 
How  does  the  color  of  the  breast  of  the  young  differ  from  that  of  the 
parent  ? 

15.  How  does  the  father  bird  protect  the  nestlings  from  other  birds, 
cats  and  snakes? 

1 6 . Does  the  mocker  select  certain  places  for  his  own  hunting  grounds 
and  drive  off  other  mockers  which  trespass? 

17.  Describe  the  colors  of  the  mockingbird  as  follows:  Beak,  head, 

back,  tail,  wings,  throat,  breast,  under  parts  and  feet. 

1 8.  What  is  the  natural  food  of  the  mockingbirds  and  how  do  they 
benefit  the  farmer?  How  does  the  mocker  act  when  attacking  a ground 
beetle  ? 

19.  Have  you  seen  mockingbirds  frighten  other  birds  by  imitating 
the  cry  of  a hawk?  Have  you  seen  them  play  other  kinds  of  tricks? 

20.  Write  a little  story  which  shall  include  your  own  observations  on 
the  ways  of  pet  mockingbirds  which  you  have  known.

“Soft  and  low  the  song  began:  I scarcely  caught  it  as  it  ran 

Through  the  melancholy  trill  of  the  plaintive  whip-poor-will , 

Through  the  ringdove's  gentle  wail,  chattering  jay  and  whistling  quail. 
Sparrow's  twitter,  catbird's  cry,  redbird's  whistle,  robin's  sigh; 

Blackbird,  bluebird,  swallow,  lark,  each  his  native  note  might  mark. 

Oft  he  tried  the  lesson  o'er,  each  time  louder  than  before; 

Burst  at  length  the  finished  song,  loud  and  clear  it  poured  along; 

All  the  choir  in  silence  heard,  hushed  before  this  wondrous  bird. 

All  transported  and  amazed,  scarcely  breathing,  long  I gazed. 

Now  it  reached  the  loudest  swell;  lower,  lower,  now  it  fell, — 

Lower,  lower,  lower  still,  scarce  it  sounded  o'er  the  rill." 

— Joseph  Rodman  Drake.

THE  CATBIRD 

Teacher's  Story 

“ The  Catbird  sings  a crooked  song,  in  minors  that  are  flat, 

And,  when  he  can't  control  his  voice  he  mews  just  like  a cat. 

Then  nods  his  head  and  whisks  his  tail  and  lets  it  go  at  that." 

— Oliver  Davie. 

As  a performer,  the  catbird  distinctly  belongs  to  the  vaudeville,  even 
going  so  far  as  to  appear  in  slate-colored  tights.  His  specialties  range 
from  the  most  exquisite  song  to  the  most  strident  of  scolding  notes;  his 
nasal  “n-y-a-a-h,  n-y-a-a-h”  .is  not  so  very  much  like  the  cat’s  mew  after 
all,  but  when  addressed  to  the  intruder  it  means  “get  out;”  and  not  in  the 
whole  gamut  of  bird  notes  is  there  another  which  so  quickly  inspires  the 
listener  with  this  desire.  I once  trespassed  upon  the  territory  of  a well- 
grown  catbird  family  and  the  squalling  that  ensued  wTas  ear-splitting;  as 
I retreated,  the  triumphant  youngsters  followed  me  for  a few  rods  with 
every  sign  of  triumph  in  their  actions  and  voices;  they  obviously  enjoyed 
my  apparent  fright.  The  catbirds  have  rather  a pleasant  “cluck,  cluck” 
when  talking  to  each  other,  hidden  in  the  bushes,  and  they  also  have  a 
variety  of  other  notes.  The  true  song  of  the  catbird,  usually  given  in  the 
early  morning,  is  very  beautiful.  Mr.  Mathews  thinks  it  is  a medley 
gathered  from  other  birds,  but  it  seems  to  me  very  individual.  However, 
true  to  his  vaudeville  training,  this  bird  is  likely  to  introduce  into  the 
middle  or  at  the  end  of  his  exquisite  song  some  phrase  that  suggestshis 
cat  call.  He  is,  without  doubt,  a true  mocker  and  will  often  imitate 
the  robin’s  song,  and  also  if  opportunity  offers  learns  to  converse  fluently 
in  chicken  language.  One  spring  morning,  I heard  outside  my  window 


Bird  Study 


99 


the  mellow  song  of  the  cardinal,  which  is  a rare  visitor  in  New  York,  but 
there  was  no  mistaking  the  “tor-re-do,  tor-re-do.”  I sprang  from  my  bed 
and  rushed  to  the  window  only  to  see  a catbird  singing  the  cardinal  song, 
and  thus  telling  me  that  he  had  come  from  the  sunny  South  and  the 
happy  companionship  of  these  brilliant  birds.  Often  when  the  catbird  is 
singing,  he  sits  on  the  topmost  spray  of  some  shrub  lifting  his  head  and 
depressing  his  tail,  like  a brown  thrasher;  and  again,  he  sings  completely 
hidden  in  the  thicket. 

In  appearance  the  catbird  is  tailor-made,  belonging  to  the  same  social 
class  as  the  cedar-bird  and  the  bam  swallow.  However,  it  affects  quiet 
colors,  and  its  well-fitting  costume  is  all  slate-gray  except  the  top  of  the 
head  and  the  tail  which  are  black;  the  feathers  beneath  the  base  of  the 
tail  are  brownish.  The  catbird  is  not  so  large  as  the  robin,  and  is  of  very 
different  shape;  it  is  far  more  slender  and  has  a long,  emotional  tail. 
The  way  the  catbird  twitches  and  tilts  its  tail,  as  it  hops  along  the  ground 
or  alights  in  a bush,  is  very  characteristic.  It  is  a particularly  alert  and 
nervous  bird,  always  on  the  watch  for  intruders,  and  the  first  to  give 
warning  to  all  other  birds  of  their  approach.  It  is  a good  fighter  in 
defending  its  nest,  and  there  are  several  observed  instances  where  it  has 
fought  to  defend  the  nest  of  other  species  of  birds;  and  it  has  gone  even 
further  in  its  philanthropy,  by  feeding  their  orphaned  nestlings. 

The  catbird  chooses  a nesting  site  in  a low  tree  or  shrub  or  brier,  where 
the  nest  is  built  usually  about  four  feet  from  the  ground.  The  nest  looks 
untidy,  but  is  strongly  made  of  sticks,  coarse  grass,  weeds,  bark  strips 
and  occasionally  paper;  it  is  lined  with  soft  roots  and  is  almost  always 
well  hidden  in  dense  foliage.  The  eggs  are  from  three  to  five  in  number 
and  are  dark  greenish  blue.  Both  parents  work  hard  feeding  the  young 
and  for  this  purpose  destroy  many  insects  which  we  can  well  spare. 
Sixty-two  per  cent,  of  the  food  of  the  young  has  been  found  in  one  instance 
to  be  cutworms,  showing  what  a splendid  work  the  parents  do  in  our 
gardens.  In  fact,  during  a large  part  of  the  summer,  while  these  birds 
are  rearing  their  two  broods,  they  benefit  us  greatly  by  destroying  the 
insect  pests;  and  although  later  they  may  attack  our  fruits  and  berries,  it 
almost  seems  as  if  they  had  earned  the  right  to  their  share.  If  we  only 
had  the  wisdom  to  plant  along  the  fences  some  elderberries  or  Russian 
mulberries,  the  catbirds  as  well  as  the  robins  would  feed  upon  them  instead 
of  the  cultivated  fruits. 

The  catbirds  afford  a striking  example  for  impressing  upon  children 
that  each  species  of  birds  haunts  certain  kinds  of  places.  The  catbirds  are 
never  found  in  deep  woods  nor  in  open  fields,  but  always  near  low  thickets 
along  streams,-  and  in  shrubbery  along  fences,  in  tangles  of  vines,  and 
especially  do  they  like  to  build  about  our  gardens,  if  we  protect  them. 
They  are  very  fond  of  bathing,  and  if  fresh  water  is  given  them  for  this 
purpose,  we  may  have  opportunity  to  witness  the  most  thorough  bath  a 
bird  can  take.  A catbird  takes  a long  time  to  bathe  and  preen 'its  feathers 
and  indulges  in  most  luxurious  sun  baths  and  thus  deservedly  earns  the 
epithet  of  “well-groomed;”  it  is  one  of  the  most  intelligent  of  all  our  birds 
and  soon  learns  “what  is  wdiat,”  and  repays  in  the  most  surprising  way 
the  trouble  of  careful  observation.

LESSON  XXIII 
The  Catbird 

Leading  thought — The  catbird  has  a beautiful  song  as  well  as  the  harsh 
“miou,”  and  can  imitate  other  birds,  although  not  so  well  as  the  mocking- 
bird. It  builds  in  low  thickets  and  shrubbery  and  during  the  nesting 
season  is  of  great  benefit  to  our  gardens. 

Methods — First,  let  the  pupils  study  and  report  upon  the  songs, 
scoldings  and  other  notes  of  this  our  northern  mockingbird;  then  let 
them  describe  its  appearance  and  habits.  Of  course,  the  study  must  be 
made  outside  of  school  hours  in  the  field. 

Observations — i.  Do  you  think  the  squall  of  the  catbird  sounds  like 
the  mew  of  a cat  ? When  does  the  bird  use  this  note  and  what  for  ? What 
other  notes  have  you  heard  it  utter? 

2.  Describe  as  well  as  you  can  the  catbird’s  true  song.  Are  there  any 
harsh  notes  in  it  ? Where  does  he  sit  while  singing  ? Describe  his  actions 
while  singing. 

3.  Have  you  ever  heard  the  catbird  imitate  the  songs  of  other  birds 
or  other  noises  ? 

4.  Describe  the  catbird  as  follows:  its  size  and  shape  compared  to 
the  robin;  the  color  and  shape  of  head,  beak,  wings,  tail,  breast  and 
under  parts. 

5.  Describe  its  peculiar  actions  and  its  characteristic  movements. 

6.  Where  do  catbirds  build  their  nests?  How  high  from  the  ground? 
What  material  is  used?  Is  the  nest  compact  and  carefully  finished? 
Is  it  hidden  ? 

7.  What  is  the  color  of  the  eggs?  Do  both  parents  care  for  the 
young? 

8.  What  is  the  food  of  the  catbird?  Why  is  it  an  advantage  to  us  to 
have  catbirds  build  in  our  gardens? 

9.  Do  you  ever  find  catbirds  in  the  deep  wroods  or  out  in  the  open 
meadows  ? Where  do  you  find  them  ? 

10.  Put  out  a pan  of  water  where  the  catbirds  can  use  it  and  then 
watch  them  make  their  toilets  and  describe  the  process.  Describe  how 
they  take  sun  baths.

This  madcap  cousin  of  robin  and  thrush. 

And  sings  without  ceasing  the  whole  morning  long ; 

Now  wild,  now  tender,  the  wayward  song 
That  flows  from  his  soft , gray,  fluttering  throat; 

But  often  he  stops  in  his  sweetest  note, 

And,  shaking  a flower  from  the  blossoming  bough.

THE  BELTED  KINGFISHER 
Teacher's  Story 

HIS  patrol  of  our  streams  and  lake  shores,  in  his  cadet 
uniform,  is  indeed  a military  figure  as  well  as  a militant 
personality.  As  he  sits  upon  his  chosen  branch  over- 
hanging some  stream  or  lake  shore,  his  crest  abristle, 
his  keen  eye  fixed  on  the  water  below,  his  whole  bearing 
alert,  one  must  acknowledge  that  this  fellow  puts 
“ginger”  into  his  environment,  and  that  the  spirit 
which  animates  him  is  very  far  from  the  ildolce  far 
niente ” which  permeates  the  ordinary  fisherman.  However,  he  does  not 
fish  for  fun  but  for  business;  his  keen  eye  catches  the  gleam  of  a moving 
fin  and  he  darts  from  his  perch,  holds  himself  for  a moment  on  steady 
wings  above  the  surface  of  the  water,  to  be  sure  of  his  quarry,  and  then 
there  is  a dash  and  a splash  and  he  returns  to  his  perch  with  the  wriggling 
fish  in  his  strong  beak;  he  at  once  proceeds  to  beat  its  life  out  against  a 
branch  and  then  to  swallow  it  sensibly,  head  first,  so  that  the  fins  will  not 
prick  his  throat  nor  the  scales  rasp  it.  He  swallows  the  entire  fish,  trust- 
ing to  his  internal  organs  to  select  the  nourishing  part ; and  later  he  gulps 
up  a ball  of  the  indigestible  scales  and  bones. 

The  kingfisher  is  very  different  in  form  from  an  ordinary  bird;  he  is 
larger  than  a robin,  and  his  head  and  fore  parts  are  much  larger  in  propor- 
tion; this  is  the  more  noticeable  because  of  the  long 
feathers  of  the  head  which  he  lifts  into  a crest,  and 
because  of  the  shortness  of  the  tail.  The  beak  is  very 
long  and  strong  in  order  to  seize  the  fish  and  hold  it 
fast;  but  the  legs  are  short  and  weak;  the  third  and 
fourth  toes  are  grown  together  for  a part  of  their 
length;  perhaps  this  is  of  use  to  the  bird  in  pushing 
earth  from  the  burrow,  when  excavating.  The  king- 
fisher has  no  need  for  running  and  hopping,  like  the 
robin  and,  therefore,  does  not  need  the  robin’s  strong 
legs  and  feet . His  colors  are  beautiful  and  harmonious ; 
the  upper  parts  are  grayish  blue,  the  throat  and  collar 
white,  as  is  also  the  breast,  which  has  a bluish  gray 
band  across  the  upper  part,  this  giving  the  name  of 
the  Belted  Kingfisher  to  the  bird.  The  feathers  of  the  wings  are  tipped  with 
white  and  the  tail  feathers  narrowly  barred  with  white.  The  under  side 
of  the  body  is  white  in  the  males,  while  in  the  females  it  is  somewhat  chest- 
nut in  color.  There  is  a striking  white  spot  just  in  front  of  the  eye. 

The  kingfisher  parents  build  their  nest  in  a burrow  which  they  tunnel 
horizontally  in  a bank ; sometimes  there  is  a vestibule  of  several  feet 
before  the  nest  is  reached,  and  at  other  times  it  is  built  very  close  to  the 
opening.  Both  parents  are  industrious  in  catching  fish  for  their  nestlings, 
but  the  burden  of  this  duty  falls  heaviest  upon  the  male.  Many  fish 
bones  are  found  in  the  nest,  and  they  seem  so  clean  and  white  that  they 
have  been  regarded  as  nest  lining.  Wonderful  tales  are  told  of  the  way 
the  English  kingfishers  use  fish  bones  to  support  the  earth  above  their 
nests,  and  tributes  have  been  paid  to  their  architectural  skill.  But  it  is 
generally  conceded  that  the  lining  of  fish  bones  in  nests  of  our  kingfisher 
is  incidental,  since  the  food  of  the  young  is  largely  fish,  although  frogs,

insects  and  other  creatures  are  often  eaten  with  relish.  It  is  interesting 
to  note  the  process  by  which  the  young  kingfisher  gets  its  skill  in  fishing. 

I have  often  seen  one  dive  horizontally  for  a yard  or  two  beneath  the 
water  and  come  up  indignant  and  sputtering  because  the  fish  had  escaped. 
It  was  fully  two  weeks  after  this  before  this  one  learned  to  drop  like  a 
bullet  on  its  quarry. 

The  note  of  the  kingfisher  is  a loud  rattle,  not  especially  pleasant  close 
at  hand,  but  not  unmusical  at  a little  distance.  It  is  a curious  coinci- 
dence that  it  sounds  very  much  like  the  clicking  of  the  fisherman’s  reel; 
it  is  a sound  that  conjures  visions  of  shade-dappled  streams  and  the  danc- 
ing, blue  waters  of  tree-fringed  lakes  and  ponds. 

There  seems  to  be  a division  of  fishing  ground  among  the  kingfishers, 
one  bird  never  trespassing  upon  its  neighbor’s  preserves.  Unless  it  be 
the  parent  pair  working  near  each  other  for  the  nestlings,  or  the  nestlings 
still  under  their  care,  we  never  see  two  kingfishers  in  the  same  immediate 
locality.

LESSON  XXIV 
The  Kingfisher 

Leading  thought — The  kingfisher  is  fitted  by 
form  of  body  and  beak  to  be  a fisherman. 

Methods — If  the  school  be  near  a stream  or 
pond  the  following  observations  may  be  made 
by  the  pupils;  otherwise  let  the  boys  who  go 
fishing  make  a study  of  the  bird  and  report  to 
the  school. 

Observations — 1.  Where  have  you  seen 
the  kingfisher?  Have  you  often  seen  it  on  a 
certain  branch  which  is  its  favorite  perch?  Is 
this  perch  near  the  water?  What  is  the 
advantage  of  this  position  to  the  bird? 

2.  What  does  the  kingfisher  feed  upon? 
How  does  it  obtain  its  food?  Describe  the 
actions  of  one  of  these  birds  while  fishing. 

3 . With  what  weapons  does  the  kingfisher  secure  the  fish  ? How  long 
is  its  beak  compared  with  the  rest  of  its  body  ? How  does  it  kill  the  fish  ? 
Does  it  swallow  the  fish  head  or  tail  first?  Why?  Does  it  tear  off  the 
scales  or  fins  before  swallowing  it  ? How  does  it  get  rid  of  these  and  the 
bones  of  the  fish  ? 

4.  Which  is  the  larger,  the  kingfisher  or  the  robin?  Describe  the 
difference  in  shape  of  the  bodies  of  these  two  birds;  also  in  the  size  and 
shape  of  feet  and  beaks  and  explain  why  they  are  so  different  in  form. 
What  is  there  peculiar  about  the  kingfisher’s  feet?  Do  you  know  which 
two  toes  are  grown  together  ? 

5.  What  are  the  colors  of  the  kingfisher  in  general?  The  colors  of 
head,  sides  of  head,  collar,  back,  tail,  wings,  throat,  breast  and  under 
parts  ? Is  there  a white  spot  near  the  eye  ? If  so,  where  ? Do  you  know 
the  difference  in  colors  between  the  parent  birds  ? 

6.  Where  is  the  nest  built ? How  is  it  lined?

7.  What  is  the  note  of  the  kingfisher?  Does  it  give  it  while  perching 
or  while  on  the  wing?  Do  you  ever  find  more  than  one  kingfisher  on  the 
same  fishing  grounds  ?

THE  KINGFISHER  (OF  ENGLAND ) 

For  the  handsome  Kingfisher,  go  not  to  the  tree, 

No  bird  of  the  field  or  the  forest  is  he; 

In  the  dry  river  rock  he  did  never  abide, 

And  not  on  the  brown  heath  all  barren  and  wide. 

He  lives  where  the  fresh,  sparkling  waters  are  flowing, 

Where  the  tall  heavy  Typha  and  Loosestrife  are  growing ; 

By  the  bright  little  streams  that  all  joyfully  run 
Awhile  in  the  shadow,  and  then  in  the  sun. 

He  lives  in  a hole  that  is  quite  to  his  mind, 

With  the  green  mossy  Hazel  roots  firmly  entwined; 

Where  the  dark  Alder-bough  waves  gracefully  o'er, 

And  the  Sword- flag  and  Arrow-head  grow  at  his  door. 

There  busily,  busily,  all  the  day  long, 

He  seeks  for  small  fishes  the  shallows  among; 

For  he  builds  his  nest  of  the  pearly  fish-bone, 

Deep,  deep,  in  the  bank,  far  retired,  and  alone. 

Then  the  brown  Water-Rat  from  his  burrow  looks  out , 

To  see  what  his  neighbor  Kingfisher' s about; 

And  the  green  Dragon-fly,  flitting  slowly  away, 

Just  pauses  one  moment  to  bid  him  good-day. 

O happy  Kingfisher!  What  care  should  he  know. 

By  the  clear,  pleasant  streams,  as  he  skims  to  and  fro. 

Now  lost  in  the  shadow,  now  bright  in  the  sheen 
Of  the  hot  summer  sun,  glancing  scarlet  and  green!

THE  SCREECH  OWL 
Teacher's  Story 

“ Disquiet  yourselves  not:  lTis  nothing  hut  a little,  downy  owl.” — Shelley. 


Of  all  the  fascinating 
sounds  to  be  heard  at  night 
in  the  woods,  the  screech 
owl’s  song  is  surely  the 
most  so ; its  fascination  does 
not  depend  on  music  but 
upon  the  chills  which  it 
sends  up  and  down  the 
spine  of  the  listener,  thus 
attacking  a quite  different 
set  of  nerves  than  do  other 
bird  songs.  The  weird  wail, 
tremulous  and  long  drawn 
out,  although  so  blood- 
curdling, is  from  the  stand- 
point of  the  owlet  the  most 
beautiful  music  in  the 
world;  by  means  of  it  he 
calls  to  his  mate,  cheering 
her  with  the  assurance 
of  his  presence  in  the 
world ; evidently  she  is  not 
a nervous  creature.  The 
screech  owls  are  likely  to 
sing  at  night  during  any 
part  of  the  year;  nor  should 
Screech  owls.  we  infer  that  when  they  are 

From  Country  Life  in  America.  singing  they  are  not  hunt- 

ing, for  perchance  their  music  frightens  their  victims  into  fatal  activ- 
ity. Although  the  note  is  so  unmistakable,  yet  there  is  great  varia- 
tion in  the  songs  of  individuals;  the  great  variety  of  quavers  in  the 
song  offering  ample  opportunity  for  the  expression  of  individuality. 
Moreover,  these  owls  often  give  themselves  over  to  tremulous 
whispering  and  they  emphasize  excitement  by  snapping  their  beaks  in 
an  alarming  manner. 

Any  bird  that  is  flying  about  and  singing  in  the  night  time  must  be  able 
to  see  where  it  is  going,  and  the  owls  have  special  adaptations  for  this. 
The  eyes  are  very  large  and  the  yellow  iris  opens  and  closes  about  the  pupil 
quite  similar  to  the  arrangement  in  the  cat’s  eye,  except  that  the  pupil  in 
the  owl’s  eye  is  round  when  contracted  instead  of  elongated;  in  the  night 
this  pupil  is  expanded  until  it  covers  most  of  the  eye.  The  owl  does  not 
need  to  see  behind  and  at  the  sides,  since  it  does  not  belong  to  the  birds 
which  are  the  victims  of  other  birds  and  animals  of  prey.  The  owl  is  a 
bird  that  hunts  instead  of  being  hunted,  and  it  needs  only  to  focus  its  eyes 
on  the  creature  it  is  chasing.  Thus,  its  eyes  are  in  the  front  of  the  head 
like  our  own;  but  it  can  see  behind,  in  case  of  need,  for  the  head  turns 
upon  the  neck  as  if  it  were  fitted  on  a ball-bearing  joint.  I have  often 


Bird  Study 


io5 

amused  myself  by  walking  around  a captive  screech  owl,  which  would 
follow  me  with  its  eyes  by  turning  the  head  until  it  almost  made  the 
circle,  then  the  head  would  twist  back  with  such  lightning  rapidity  that  I 
could  hardly  detect  the  movement;  it  seemed  almost  as  if  the  head  was 
on  a pivot  and  could  be  moved  around  and  around  indefinitely.  Al- 
though the  owl,  like  the  cat,  has  eyes  fitted  for  night  hunting,  it  can  also 
see  fairly  well  during  the  daytime. 

A beak  with  the  upper  mandible  ending  in  a sharp  hook  signifies  that 
its  owner  lives  upon  other  animals  and  needs  to  rend  and  tear  flesh. 
The  owl’s  beak  thus  formed  is  somewhat  buried  in  the  feathers  of  the  face, 
which  gives  it  a striking  resemblance  to  a Roman  nose.  This,  with  the 
great,  staring,  round  eyes,  bestows  upon  the  owl  an  appearance  of  great 
wisdom.  But  it  is  not  the  beak  which  the  owl  uses  for  a weapon  of 
attack;  its  strong  feet  and  sharp,  curved  claws  are  its  weapons  for  striking 
the  enemy  and  also  for  grappling  with  its  prey.  The  outer  toe  can  be 
moved  back  at  will,  so  that  in  grasping  its  prey  or  its  perch,  two  toes  may 
be  directed  forward  and  two  backward,  thus  giving  a stronger  hold. 

The  ear  is  very  different  in  form  from  the  ear  of  other  birds ; instead 
of  being  a mere  hole  opening  into  the  internal  ear,  it  consists  of  a fold  of 
skin  forming  a channel  which  extends  from  above  the  eye  around  to  the 
side  of  the  throat.  (See  The  Bird,  Beebe,  p.  217).  Thus  equipped, 
while  hunting  in  the  dark  the  owl  is  able  to  hear  any  least  rustle  of  mouse 
or  bird  and  to  know  in  which  direction  to  descend  upon  it.  There  has 
been  no  relation  established  between  the  ear  tufts  of  the  screech  owl  and 
its  ears,  so  far  as  I know,  but  the  way  the  bird  lifts  the  tufts  when  it  is 
alert,  always  suggests  that  this  movement  in  some  way  opens  up  the  ear 

In  color  there  are  two  types  among  the  screech  owls,  one  reddish 
brown,  the  other  gray.  The  back  is  streaked  with  black,  the  breast  is 
marked  with  many  shaft-lines  of  black.  The  whole  effect  of  the  owl’s 
plumage  makes  it  resemble  a branch  of  a tree  or  a part  of  the  bark,  and 
thus  it  is  protected  from  prying  eyes,  during  the  daytime  when  it  is  sleep- 
ing. Its  plumage  is  very  fluffy  and  its  wing  feathers,  instead  of  being 
stiff  to  the  very  edge,  have  soft  fringes  which  cushion  the  stroke  upon  the 
air.  The  owl’s  flight  is,  therefore,  absolutely  noiseless  and  the  bird  is  thus 
able  to  swoop  down  upon  its  prey  without  giving  warning  of  its  approach. 

The  screech  owls  are  partial  to  old  apple  orchards  for  nesting  sites. 
They  will  often  use  an  abandoned  nest  of  a woodpecker;  the  eggs  are 
almost  as  round  as.  marbles  and  as  white  as  chalk,  showing  very  clearly 
that  they  are  laid  within  a dark  hole,  otherwise  their  color  would  attract 
the  eyes  of  enemies.  There  are  usually  four  eggs;  the  fubsy  little  owlets 
climb  out  of  their  home  cave  by  the  end  of  May  and  are  the  funniest  little 
creatures  imaginable.  They  make  interesting  but  decidedly  snappy  pets; 
they  can  be  fed  on  insects  and  raw  beef.  It  is  most  interesting  to  see  one 
wake  up  late  in  the  afternoon  after  its  daytime  sleep.  All  day  it  has  sat 
motionless  upon  its  perch  with  its  toes  completely  covered  with  its  fluffy 
feather  skirt.  Suddenly  its  eyes  open,  the  round  pupils  enlarging  or  con- 
tracting with  great  rapidity  as  if  adjusting  themselves  to  the  amount  of 
light.  When  the  owl  winks  it  is  like  a moon  in  eclipse,  so  large  are  the 
eyes,  and  so  entirely  are  they  obscured  by  the  lids  which  seem  like  circular 
curtains.  When  it  yawns,  it<?  wide  bill  absurdly  resembles  a human  mouth, 
and  the  yawn  is  very  human  in  its  expression.  It  thetj  stretches  its  wings 
and  it  is  astonishing  how  long  this  wing  can  be  extended  below  the  feet.

It  then  begins  its  toilet.  It  dresses  its  feathers  with  its  short  beak, 
nibbling  industriously  in  the  fluff;  it  scratches  its  under  parts  and  breast 
with  its  bill,  then  cleans  the  bill  with  its  foot,  meanwhile  moving  the  head 
up  and  down  as  if  in  an  attempt  to  see  better  its  surroundings. 

The  owls  are  loyal  lovers  and  are  said  to  remain  mated  through  life, 
the  twain  being  very  devoted  to  their  nests  and  nestlings.  Sometimes 
the  two  wise-looking  little  parents  sit  together  on  the  eggs,  a most  happy 
way  to  pass  the  wearisome  incubation  period. 

The  screech  ow'ls  winter  in  the  north  and  they  are  distinctly  fore- 
sighted  in  preparing  for  winter.  They  have  often  been  observed  catching 
mice,  during  the  late  fall,  and  placing  them  in  some  hollow  tree  for  cold 
storage,  whence  they  may  be  taken  in  time  of  need.  Their  food  consists 
to  some  extent  of  insects,  especially  night-flying  moths  and  beetles,  also 
caterpillars  and  grasshoppers.  However,  the  larger  part  of  their  food  is 
mice;  sometimes  small  birds  are  caught  and  the  English  sparrow  is  a fre- 
quent victim.  Chickens  are  rarely  taken,  except  when  small,  since  this 
owlet  is  not  as  long  as  a robin.  It  swallows  its  quarry  as  whole  as  possi- 
ble, trusting  to  its  inner  organs  to  do  the  sifting  and  selecting.  Later  it 
throws  up  pellets  of  the  indigestible  bones,  hair,  etc.  By  the  study  of 
these  pellets,  found  under  owl  roosts,  the  scientists  have  been  able  to 
determine  the  natural  food  of  the  bird,  and  they  all  unite  in  assuring  us 
that  the  screech  owl  does  the  farmer  much  more  good  than  harm,  since  it 
feeds  so  largely  upon  creatures  which  destroy  his  crops. 


LESSON  XXV 

The  Screech  Owl 

Leading  thought — This  owl  is  especially  adapted  to  get  its  prey  at  night. 
It  feeds  largely  on  field  mice,  grasshoppers,  caterpillars  and  other  in- 
jurious insects  and  is  therefore  the  friend  of  the  farmer. 

Method — This  lesson  should  begin  when  the  children  first  hear  the  cry 
of  this  owl;  and  an  owlet  in  captivity  is  a fascinating  object  for  the 
children  to  observe.  However,  it  is  so  important  that  the  children  learn 
the  habits  of  this  owl  that  the  teacher  is  advised  to  hinge  the  lesson  on  any 
observation  whatever  made  by  the  pupils,  and  illustrate  it  with  pictures 
and  stories. 

Observations — i.  Have  you  ever  heard  the  screech  owl?  At  what 
time  of  the  day  or  night?  Why  was  this?  Why  does  the  owl  screech? 
How  did  you  feel  when  listening  to  the  owl’s  song? 

2.  Describe  the  owl’s  eyes.  Are  they  adapted  to  see  by  night? 
What  changes  take  place  in  them  to  enable  the  owl  to  see  by  daytime  also? 
In  what  way  are  the  owl’s  eyes  similar  to  the  cat’s?  Why  is  it  necessary 
for  an  owl  to  see  at  night?  Are  the  owl’s  eyes  placed  so  that  they  can 
see  at  the  sides  like  other  birds.  How  does  it  see  an  object  at  the  sides  or 
behind  it? 

3.  Note  the  owl’s  beak.  For  what  purpose  is  a hooked  beak?  How 
does  the  owl  use  its  beak?  Why  do  we  think  that  the  owl  looks  wise? 

4.  Describe  the  feet  and  claws  of  the  screech  owl.  What  are  such 
sharp  hooked  claws  meant  for?  Does  an  owl  on  a perch  always  have  three 
toes  directed  forward  and  one  backward  ? 


Bird  Study 


107 

5.  Describe  the  colors  of  the  screech  owl.  Are  all  these  owls  of  the 
same  color?  How  do  these  colors  protect  the  bird  from  its  enemies? 

6.  How  is  the  owl’s  plumage  adapted  to  silent  flight?  Why  is  silent 
flight  advantageous  to  this  bird? 

7.  How  does  the  owl’s  ear  differ  from  the  ears  of  other  birds?  Of 
what  special  advantage  is  this?  As  the  owl  hunts  during  the  night,  what 
does  it  do  in  the  daytime?  How  and  by  what  means  does  it  hide  itself? 

8.  Where  does  the  screech  owl  make  its  nest?  Do  you  know  any- 
thing about  the  devotion  of  the  parent  owls  to  each  other  and  to  their 
young?  How  many  eggs  are  laid?  What  is  their  color?  At  what  time 
of  year  do  the  little  owls  appear? 

9 Where  does  the  screech  owl  spend  the  winter?  What  do  the 
screech  owls  feed  upon  ? Do  they  chew  their  food  ? How  do  they  get  rid 
of  the  indigestible  portion  of  their  food?  How  does  this  habit  help  the 
scientists  to  know  the  food  of  the  owls? 

10.  How  does  the  screech  owl  work  injury  to  the  farmers?  How  does 
it  benefit  them?  Does  not  the  benefit  outweigh  the  injury? 

11.  How  many  other  kinds  of  owls  do  you  know?  What  do  you 
know  of  their  habits?

TWO  WISE  OWLS 

We  are  two  dusky  owls,  and  we  live  in  a tree; 

Look  at  her, — look  at  me! 

Look  at  her, — she's  my  mate,  and  the  mother  of  three 
Pretty  owlets,  and  we 

Have  a warm  cosy  nest,  just  as  snug  as  can  he. 

We  are  both  very  wise;  for  our  heads,  as  you  see, 

{Look  at  her — look  at  me!) 

Are  as  large  as  the  heads  of  four  birds  ought  to  be; 

And  our  horns,  you'll  agree, 

Make  us  look  wiser  still,  sitting  here  on  the  tree. 

And  we  care  not  how  gloomy  the  night-time  may  be; 

We  can  see, — we  can  see 
Through  the  forest  to  roam,  it  suits  her,  it  suits  me; 

And  we're  free, — we  are  free 
T o bring  back  what  we  find,  to  our  nest  in  the  tree.

Red-tailed  hawk  on  nest.

THE  HEN  HAWKS 
Teacher's  Story 

11  Above  the  tumult  of  the  canon  lifted,  the  gray  hawk  breathless  hung, 

Or  on  the  hill  a winged  shadow  drifted  where  furze  and  ihornbush  clung.” 

— Bret  Harte. 

It  is  the  teacher’s  duty  and  privilege  to  try  to  revolutionize  some 
popular  misconceptions  about  birds,  .and  two  birds,  in  great  need  in  this 
respect,  are  the  so-called  hen  hawks.  They  are  most  unjustly  treated, 
largely  because  most  farmers  consider  that  a “hawk  is  a hawk,”  and  should 
always  be  shot  to  save  the  poultry,  although  there  is  as  much  difference 
in  the  habits  of  hawks  as  there  is  in  those  of  men.  The  so-called  hen 
hawks  are  the  red-shouldered  and  the  red-tailed  species,  the  latter  being 
somewhat  the  larger  and  rarer  of  the  two ; both  are  very  large  birds ; the 
red-shouldered  has  cinnamon  brown  epaulets,  the  tail  blackish,  crossed 
by  five  or  six  narrow  white  bars,  and  the  wing  feathers  are  also  barred. 
The  red-tailed  species  has  dark  brown  wings,  the  feathers  not  barred,  and 
is  distinguished  by  its  tail  which  is  brilliant  cinnamon  color  with  a black 
bar  across  it  near  the  end;  it  is  silvery  white  beneath.  When  the  hawk 
is  soaring,  its  tail  shows  reddish  as  it  wheels  in  the  air.  Both  birds  are 
brown  above  and  whitish  below,  streaked  with  brown. 

The  flight  of  these  hawks  is  alike  and  is  very  beautiful;  it  consists  of 
soaring  on  outstretched  wings  in  wide  circles  high  in  the  air,  and  is  the 
ideal  of  graceful  aerial  motion.  In  rising,  the  bird  faces  the  wind  and 
drops  a little  in  the  circle  as  its  back  turns  to  the  leeward,  and  thus  it 
climbs  an  invisible  winding  stair  until  it  is  a mere  speck  in  the  sky.  This 
wonderful  flight,  on  motionless  wings,  is  what  has  driven  to  despair  our 
inventors  of  airships  who  have  not  been  able  to  fathom  the  mystery  of  it 
from  a practical  standpoint.  When  the  bird  wishes  to  drop,  it  lifts  and

holds  its  wings  above  its  back,  and  comes  down  like  a lump  of  lead,  only 
to  catch  itself  whenever  it  chooses  to  begin  again  to  climb  the  invisible 
spiral.  And  all  this  is  done  without  fatigue,  for  these  birds  have  been 
observed  to  soar  thus  for  hours  together  without  coming  to  earth.  When 
thus  soaring  the  two  species  may  be  distinguished  from  each  other  by 
their  cries;  the  red-tailed  gives  a high  sputtering  scream,  which  Chapman 
likens  to  the  sound  of  escaping  steam;  while  the  red-shouldered  calls  in  a 
high  not  unmusical  note  “kee-you,  kee-you”  or  “tee-ur,  tee-ur.” 

The  popular  fallacy  for  the  teacher  to  correct  about  these  birds,  is  that 
they  are  enemies  of  the  farmers.  Not  until  one  has  actually  been  seen  to 
catch  the  chickens  should  it  be  shot,  for  very  few  of  them  are  guilty  of  this 
sin.  Sixty-six  per  cent,  of  the  food  of  the  red-tailed  species  consists  of 
injurious  animals,  i.  e.,  mice  and  gophers,  etc.,  and  only  7 per  cent,  con- 
sists of  poultry;  the  victims  are  probably  old  or  disabled  fowls,  and  fall 
an  easy  prey;  this  bird  much  prefers  mice  and  reptiles  to  poultry.  The 
more  common  red-shouldered  hawk  feeds  generally  on  mice,  snakes, 
frogs,  fish  and  is  very  fond  of  grasshoppers.  Ninety  per  cent,  of  its  food 
consists  of  creatures  which  injure  our  crops  or  pastures  and  scarcely  1% 
per  cent,  is  made  up  of  poultry  and  game.  These  facts  have  been  ascer- 
tained by  the  experts  in  the  department  of  Agriculture  at  Washington 
who  have  examined  the  stomachs  of  hundreds  of  these  hawks  taken  from 
different  localities.  Furthermore,  Dr.  Fisher  states  that  a pair  of  the  red- 
shouldered hawks  bred  for  successive  years  within  a few  hundred  yards  of 
a poultry  farm,  containing  800  young  chickens  and  400  ducks,  and  the 
owner  never  saw  them  attempt  to 
catch  a fowl. 

However,  there  are  certain 
species  of  hawks  which  are  to  be 
feared;  these  are  the  Cooper’s 
hawk  and  the  sharp-shinned 
hawk,  the  first  being  very  destruc- 
tive to  poultry  and  the  latter  kill- 
ing many  wild  birds.  These  are 
both  somewhat  smaller  than  the 
species  we  are  studying.  They 
are  dark  gray  above  and  have  very 
long  tails,  and  when  flying,  they 
flap  their  wings  for  a time  and 
then  glide  a distance.  They  do 
not  soar  on  motionless  outspread 
pinions  by  the  hour. 

When  hawks  are  seen  soaring, 
they  are  likely  to  be  hunting  for 
mice  in  the  meadows  below  them ; 
their  eyes  are  remarkably  keen; 
they  can  see  a moving  creature 
from  a great  height,  and  can 
suddenly  drop  upon  it  like  a 
thunder  bolt  out  of  a clear  sky. 

Their  wonderful  eyes  are  far- 
sighted when  they  are  circling  in 

the  sky.  but  as  they  drop,  the  The  red-tailed  hawk.

focus  of  the  eyes  changes  automatically  with  great  rapidity,  so  that 
by  the  time  they  reach  the  earth  they  are  near-sighted,  a feat  quite  im- 
possible for  our  eyes  unless  aided  by  glasses  or  telescope. 

These  so-called  hen  hawks  will  often  sit  motionless,  for  hours  at  a 
time,  on  some  dead  branch  or  dead  tree;  they  are  probably  watching  for 
something  eatable  to  stir  within  the  range  of  their  keen  vision.  When 
seizing  its  prey,  a hawk  uses  its  strong  feet  and  sharp,  curved 
talons.  All  hawks  keep  their  claws  sharp  and  polished,  even  as 
the  warrior  keeps  his  sword  bright,  so  as  to  be  ready  for  use; 
the  legs  are  covered  by  a growth  of  feathers  extending  down  from  above, 
looking  like  feather  trousers.  The  beak  is  hooked  and  very  sharp  and  is 
used  for  tearing  apart  the  flesh  of  the  quarry.  When  a hawk  fights  some 
larger  animal  or  man,  it  throws  itself  over  upon  its  back  and  strikes  its 
assailant  with  its  strong  claws  as  well  as  with  its  beak;  but  the  talons  are 
its  chief  weapons. 

Both  species  build  a large,  shallow  nest  of  coarse  sticks  and  grass, 
lined  with  moss,  feathers,  etc.;  it  is  a rude,  rough  structure,  and  is  placed 
in  tall  trees  from  fifty  to  seventy-five  feet  from  the  ground.  Only  two  to 
four  eggs  are  laid;  these  are  whitish  spotted  with  brown.  These  hawks 
are  said  to  remain  mated  for  life  and  are  devoted  to  each  other  and  their 
young.  Hawks  and  eagles  are  very  similar  in  form  and  habits,  and  if  the 
eagle  is  a noble  bird  so  is  the  hawk. 


LESSON  XXVI 

The  Red-shouldered  and  Red-tailed  Hawks 

Leading  thought — Ignorant  people  consider  all  hawks  dangerous 
neighbors  because  they  are  supposed  to  feed  exclusively  on  poultry. 
This  idea  is  false  and  we  should  study  carefully  the  habits  of  hawks  before 
we  shoot  them.  The  ordinary  large  reddish  “hen-hawks,”  which  circle 
high  above  meadows,  are  doing  great  good  to  the  farmer  by  feeding  upon 
the  mice  and  other  creatures  which  steal  his  grain  and  girdle  his  trees. 

Methods — Begin  by  observations  on  the  flight  of  one  of  these  hawks 
and  supplement  this  with  such  observations  as  the  pupils  are  able  to 
make,  or  facts  which  they  can  discover  by  talking  with  hunters  or  others 
and  b}'  reading. 

Observations — i . How  can  you  tell  a hawk,  when  flying,  from  a crow 
or  other  large  bird?  Describe  how  it  soars?  Does  it  move  off  in  any 
direction;  if  so,  does  it  move  off  in  circles?  How  often  does  it  make 
strokes  with  its  wings?  Does  it  rise  when  it  is  facing  the  wind  and  fall  as 
it  turns  its  back  to  the  wind? 

2.  Have  you  seen  a hawk  flap  its  wings  many  times  and  then  soar 
for  a time?  If  so,  what  hawk  do  you  think  it  was?  How  does  it  differ 
in  habits  from  the  “hen-hawks?” 

3.  Have  you  noticed  a hawk  when  soaring  drop  suddenly  to  earth? 
If  so,  why  did  it  do  this  ? 

4.  How  does  a hawk  hunt?  How  can  it  see  a mouse  in  a meadow 
when  it  is  so  high  in  the  air  that  it  looks  like  a circling  speck  in  the  sky? 
If  it  is  so  far-sighted  as  this,  how  can  it  be  near-sighted  enough  to  catch 
the  mouse  when  it  is  close  to  it?  Would  you  not  have  to  use  field  glasses 
or  telescope  to  do  this  ?

5.  When  a hawk  alights  what  sort  of  a place  does  it  choose?  How 
does  it  act  ? 

6.  Do  hawks  seize  their  prey  with  their  claws  or  their  beaks?  What 
sort  of  feet  and  claws  has  the  hawk ? Describe  the  beak?  What  do  you 
think  this  shaped  beak  is  meant  for? 

7.  Why  do  people  shoot  hawks?  Why  is  it  a sign  of  ignorance  in 
people  to  wish  to  shoot  all  hawks? 

8.  What  is  the  food  of  the  red-shouldered  hawk  as  shown  by  the 
bulletin  of  the  U.  S.  Department  of  Agriculture  or  by  the  Audubon 
leaflets? 

9.  Where  does  the  hawk  place  its  nest?  Of  what  does  it  build  its 
nest? 

10.  Compare  the  food  and  the  nesting  habits  of  the  red-shouldered 
and  red-tailed  hawks  ? 

11.  How  devoted  are  the  hawks  to  their  mates  and  their  young? 
Does  a hawk,  losing  its  mate,  live  alone  ever  after? 

12.  Describe  the  colors  of  the  hen  hawks  and  describe  how  you  can 
tell  the  two  species  apart  by  the  colors  and  markings  of  the  tail. 

13.  What  is  the  cry  of  the  hawk  ? How  can  you  tell  the  two  species 
apart  by  this  cry?  Does  the  hawk  give  its  cry  only  when  on  the  wing? 

14.  Why  should  an  eagle  be  considered  so  noble  a bird  and  the  hawk 
be  so  scorned?  What  difference  is  there  between  them  in  habits?

The  cruel  sun  smites  with  unerring  aim, 

The  sight  and  touch  of  all  things  blinds  and  burns. 

And  bare,  hot  hills  Seem  shimmering  into  flame! 

On  outspread  wings  a hawk,  far  poised  on  high, 

Quick  swooping  screams,  and  then  is  heard  no  more: 

The  strident  shrilling  of  a locust  nigh 

Breaks  forth,  and  dies  in  silence  as  before.

THE  SWALLOWS  AND  THE  CHIMNEY  SWIFT 


Teacher's  Story 

JHESE  friendly  little  birds  spend  their  time  darting  through 
the  air  on  swift  wings,  seeking  and  destroying  insects 
which  are  foes  to  us  and  our  various  crops.  However,  it 
is  safe  to  assume  that  they  are  not  thinking  of  us  as  they 
skim  above  our  meadows  and  ponds,  hawking  our  tiny 
foes;  for  like  most  of  us,  they  are  simply  intent  upon 
getting  a living.  Would  that  we  might  perform  this 
necessary  duty  as  gracefully  as  they. 

In  general,  the  swallows  have  a long,  slender,  graceful 
body,  with  a long  tail  which  is  forked  or  notched,  except 
in  the  case  of  the  eave  swallow.  The  beak  is  short  but 
wide  where  it  joins  the  head;  this  enables  the  bird  to  open  its  mouth  wide 
and  gives  it  more  scope  in  the  matter  of  catching  insects ; the  swift  flight, 
of  the  swallows  enables  them  to  catch  insects  on  the  wing;  their  legs  are 
short,  the  feet  are  weak  and  fitted  for  perching;  it  would  be  quite  impos- 
sible for  a swallow  to  walk  or  hop  like  a robin  or  blackbird. 

The  eave , or  cliff ’,  swallows — These  swallows  build  under  the  eaves  of 
bams  or  in  similar  locations.  In  early  times  they  built  against  the  sides 
of  cliffs;  but  when  man  came  and  built  barns,  they  chose  them  for  their 
dwelling  sites.  The  nest  is  made  of  mud  pellets  and  is  somewhat  globular

in  shape,  with  an  entrance  at  one  side.  When  building  on  the  sides  of 
cliffs  or  in  unprotected  portions  of  a bam,  a covered  passage  is  built 
around  the  door,  which  gives  the  nest  the  shape  of  a gourd  or  retort ; but 
when  protected  beneath  the  eaves  the  birds  seem  to  think  this  vestibule  is 
unnecessary.  The  mud  nest  is  warmly  lined  with  feathers  and  soft 
materials,  and  there  are  often  many  nests  built  so  closely  together  that 
they  touch.  The  eave  swallow  comes  north  about  May  1st,  and  soon 
after  that,  may  be  seen  along  streams  or  other  damp  places  gathering 
mud  for  the  nests.  It  seems  necessary  for  the  bird  to  find  clay  mud  in 
order  to  render  the  nest  strong  enough  to  support  the  eggs  and  nestlings. 
The  eggs  are  white,  blotched  with  reddish  brown.  The  parents  cling  to

the  edge  of  the  nest  when  feeding  the  young.  Both  the  bam  and  eave 
swallows  are  blue  above  but  the  eave  swallow  has  the  forehead  cream 
white  and  the  rump  of  pale  brick-red,  and  its  tail  is  square  across  the  end 
as  seen  in  flight.  The  bam  swallow  has  a chestnut  forehead  and  its  outer 
tail  feathers  are  long,  making  a distinct  fork  during  flight,  and  it  is  not 
red  upon  the  rump. 

The  barn  swallows— These  birds  choose  a bam  where  there  is  a hole  in 
the  gable  or  where  the  doors  are  kept  open  all  the  time.  They  build  upon 
beams  or  rafters,  making  a cup-shaped  nest  of  layers  of  pellets  of  mud, 
with  grass  between ; it  is  well  lined  with  feathers.  The  nest  is  usually  the 
shape  of  half  of  a shallow  cup  which  has  been  cut  in  two  lengthwise,  the 
cut  side  being  plastered  against  the  side  of  the  rafter.  Sometimes  the

nests  are  more  or  less  supported  upon  a beam  or  rafter;  the  eggs  are 
white  and  dotted  with  reddish  brown.  The  barn  swallows,  aside  from 

their  constant  twittering,  have  also  a 
pretty  song.  Both  parents  work  at 
building  the  nest  and  feeding  the 
young;  there  are  likely  to  be  several 
pairs  nesting  in  the  same  building. 
The  parents  continue  to  feed  the 
young  long  after  they  have  left  the 
nest;  often  a whole  family  may  be 
seen  sitting  on  a telegraph  wire  or  wire 
fence,  the  parents  still  feeding  the  well- 
grown  youngsters.  This  species  comes 
north  in  the  latter  part  of  April  and 
leaves  early  in  September.  It  winters 
as  far  south  as  Brazil. 

The  barn  swallow  has  a distinctly 
tailor-made  appearance ; its  red-brown 
vest  and  iridescent  blue  coat,  with 
deeply  forked  “coat  tails”  give  it  an 
elegance  of  style  which  no  other  bird, ' 
not  even  the  chic  cedar  waxwing  can 
emulate. 

The  Bank  Swallow — When  we  see  a 
sandy  bank  apparently  shot  full  of 
holes  as  by  small  cannon  balls,  we 
may  know  that  we  have  found  a tenement  of  bank  swallows.  These 
birds  always  choose  the  perpendicular  banks  of  creeks  or  of  railroad  cuts 
or  of  sand  pits  for  their  nesting  sites ; they  require  a soil  sufficiently  soft 
to  be  tunneled  by  their  weak  feet,  and  yet  not  so  loose  as  to  cave  in  upon 
the  nest.  The  tunnel  may  extend  from  one  to  four  feet  horizontally  in 
the  bank  with  just  enough  diameter  to  admit  the  body  of  the  rather 
small  bird.  The  nest  is  situated  at  the  extreme  end  of  the  tunnel  and 
is  lined  with  soft  feath- 
ers and  grasses. 

The  bank  swallows 
arrive  late  in  April  and 
leave  early  in  Septem- 
ber. They  may  be  dis- 
tinguished from  the 
other  species  by  their 
grayish  color  above ; the 
throat  and  breast  are 
white  with  a broad, 
brownish  band  across 
the  breast;  the  tail  is 
slightly  forked.  The 
rough-winged  swallow, 
which  is  similar  in  habits 
to  the  bank  swallow, 
may  be  distinguished 
from  it  by  its  gray  breast 
which  has  no  dark  band.

Tree  swallows.

The  Tree  Swallow — This  graceful  little  bird  builds  naturally  in  holes  in 
trees,  but  readily  accepts  a box  if  it  is  provided.  It  begins  to  build  soon 
after  it  comes  north  in  late  April  and  it  is  well  for  us  to  encourage  the  tree 
swallows  to  live  near  our  houses  by  building  houses  for  them  and  driving 
away  the  English  sparrows.  The  tree  swallows  live  upon  many  insects 
which  annoy  us  and  injure  our  gardens  and  damage  our  orchards;  they 
are,  therefore,  much  more  desirable  neighbors  than  the  English  sparrows* 
The  tree  swallows  congregate  in  great  numbers  for  the  southern  migration 
very  early  in  the  season,  often  in  early  August.  They  are  likely  to  con- 
gregate in  marshes,  as  are  also  the  other  swallows.  In  color  the  tree 
swallow  has  a green  metallic  back  and  head,  a pure  white  breast  with  no 
band  across  it,  and  these  peculiarities 
distinguish  it  from  all  other  species. 

The  Purple  Martin — The  martin  is 
a larger  bird  than  the  largest  swallow, 
being  eight  inches  in  length,  while  the 
bam  swallow  does  not  measure  quite 
seven.  The  male  is  shining,  steel- 
blue  above  and  below;  the  female  is 
brownish  above,  has  a gray  throat, 
brownish  breast  and  is  white  beneath. 

The  martins  originally  nested  in  hol- 
low trees  but  for  centuries  have  been 
cared  for  by  man.  The  Indians  were 
wont  to  put  out  empty  gourds  for 
them  to  nest  in;  and  as  soon  as 
America  was  settled  by  Europeans, 
martin  boxes  were  built  extensively. 

But  when  the  English  sparrows  came, 
they  took  possession  of  the  boxes,  and 
the  martins  have  to  a large  extent 


A martin  house.

disappeared,  this  is  a pity  since  they  are  beneficial  birds,  feeding  upon 
insects  which  are  injurious  to  our  farms  and  gardens.  They  are 
also  delightful  birds  to  have  around,  and  we  may  possibly  induce  them  to 
come  back  to  us  by  building  houses  for  them  and  driving  away  the 
sparrows. 


The  Chimney  Swift 

HEN  the  old-fashioned  fire-places  went  out  of  use 
and  were  walled  up,  leaving  the  great  old  chimneys 
useless,  these  sociable  birds  took  possession  of 
them.  Here  they  built  their  nests  and  reared  their 
young,  and  twittered  and  scrambled  about, 
awakening  all  sleepers  in  the  neighborhood  at 
earliest  dawn,  and  in  many  ways  made  themselves 
a distinct  part  of  family  life.  With  the  disap- 
pearance of  these  old  chimneys  and  the  growing  use  of  the  smaller 
chimney,  the  swifts  have  been  more  or  less  driven  from  their  close 
association  with  people;  and  now  their  nests  are  often  found  in  hay 
barns  or  other  secluded  buildings,  although  they  still  gather  in  chim- 
neys when  opportunity  offers. 

The  chimney  swifts  originally  built  nests  in  hollow  trees  and  caves; 
but  with  the  coming  of  civilization  they  took  possession  of  the  chimneys 
disused  during  the  summer,  and  here  is  where  we  know  them  best.  The 
nests  are  shaped  like  little  wall  pockets;  they  are  made  of  small  sticks  of 
nearly  uniform  size  which  are  glued  together  and  glued  fast  to  the  chim- 
ney wall  by  means  of  the  saliva  secreted  in  the  mouth  of  the  bird.  After 
the  nesting  season,  the  swifts  often  gather  in  great  flocks  and  live  together 
in  some  large  chimney;  toward  night-fall  they  may  be  seen  circling  about 
in  great  numbers  and  dropping  into  the  mouth  of  the  chimney,  one  by 
one,  as  if  they  were  being  poured  into  a funnel.  In  the  morning  they 
leave  in  reverse  manner,  each  swift  flying  about  in  widening  circles  as  it 
leaves  the  chimney.  The  swifts  are  never  seen  to  alight  anywhere  except 
in  hollow  trees  or  chimneys  or  similar  places;  their  tiny  feet  have  sharp 
claws  for  clinging  to  the  slightest  roughness  of  the  upright  wall ; the  tail 
acts  as  a prop,  each  tail  feather  ending  in  a spine  which  is  pressed  against 
the  chimney  side  when  the  bird  alights  and  thus  enables  it  to  cling  more 
firmly.  In  this  fashion  the  swifts  roost,  practically  hung  up  against  a 
wall. 

The  swift  has  a short  beak  and  wide  mouth  which  it  opens  broadly  to 
engulf  insects  as  it  darts  through  the  air.  Chimney  swifts  have  been 
known  to  travel  at  the  rate  of  no  miles  an  hour. 

This  bird  should  never  be  confused  with  the  swallows,  for  when  flying, 
its  tail  seems  simply  a sharp  point,  making  the  whole  body  cigar-shaped. 
This  character  alone  distinguishes  it  from  the  long  tailed  swallows.  In 
color  it  is  sooty  brown,  with  a gray  throat  and  breast;  the  wings  are  long 
and  narrow  and  apparently  curved.  The  manner  of  flight  and  appear- 
ance in  the  air  make  it  resemble  the  bat  more  than  it  does  the  swallow.

LESSON  XXVII 
The  Swallows  and  Swifts 

Leading  thought — The  swallows  are  very  graceful  birds  and  are  exceed- 
ingly swift  fliers.  They  feed  upon  insects  which  they  catch  upon  the 
wing.  There  are  five  native  swallows  which  are  common — the  eave,  or 
cliff,  the  barn,  the  bank,  the  tree  swallow  and  the  purple  martin.  The 
chimney  swift,  although  often  called  so,  is  not  a swallow;  it  is  more 
nearly  related  to  the  hummingbird  than  to  the  swallows. 

Method — The  questions  should  be  given  as  an  outline  for  observation, 
and  may  be  written  on  the  blackboard  or  placed  in  the  field  notebook. 
The  pupils  should  answer  them  individually  and  from  field  observation. 
We  study  the  swifts  and  swallows  together  to  teach  the  pupils  to  distin- 
guish them  apqrt. 

Observations — 1.  What  is  the  general  shape  of  the  swallow?  What 
is  the  color  of  the  forehead,  throat,  upper  breast,  neck,  rump  and  tail? 

2.  Is  the  tail  noticeably  forked  especially  during  flight? 

3.  Describe  the  flight  of  the  swallow.  What  is  the  purpose  of  its 
long,  swift  flight?  How  are  the  swallow’s  wings  fitted  for  carrying  the 
bird  swiftly? 

4.  Describe  the  form  of  the  beak  of  the  swallow.  How  does  it  get  its 
food  ? What  is  its  food  ?

Formerly  it  was 
believed  that  this 
daintiest  of  birds 
found  the  nectar 
of  flowers  ample 
support  for  its 
active  life ; but 
the  later  methods 
of  discovering 
what  birds  eat  by 
examining  the 
contents  of  their 
stomachs,  show 
that  the  hum- 
mingbird is  an 
insect  eater  of 
most  ravenous 
appetite.  Not 

only  does  it  catch  insects  in  mid  air,  but  undoubtedly  takes  them  while 
they  are  feasting  on  the  nectar  of  the 
tubular  flowers  which  the  humming- 
bird loves  to  visit.  Incidentally,  the 
hummingbird  carries  the  pollen  for 
these  flowers  and  may  be  counted 
as  a friend  in  every  respect,  since 
usually  the  insects  in  the  nectaries 
of  the  fl  o w e r s with  long  tubu- 
lar corollas,  are  stealing  nectar  without 
giving  in  return  compensation  to  the 
flower  by  carrying  its  pollen.  Such  in- 
sects may  be  the  smaller  beetles,  ants 
and  flies.  The  adaptations  of  the  hum- 
mingbird’s beak  and  long,  double- 
tubed  tongue,  are  especially  for  secur- 
ing this  mingled  diet  of  insects  and 
nectar.  It  is  interesting  to  note  that 
the  young  hummingbirds  have  the 
beak  much  shorter  than  when  mature. 

Its  beak  is  exactly  fitted  to  probe 
those  flowers  where  the  humming- 
bird finds  its  food.  The  tongue  has  the, 
outer  edges  curved  over  making  a tube 
on  each  side.  These  tubes  are  pro- 
vided with  minute  brushes  at  the  tips 
and  thus  are  fitted  both  for  sucking 
nectar  and  for  sweeping  up  the  insects.

can  tropics.  Our  one  species  east  of  the  Rocky  Mountains  with  which  we 
are  all  familiar  has  a ruby  throat.  This  comes  to  us  after  a very  long 
journey  each  year.  One  species  on  the  Pacific  Coast  is  known  to  travel 
three  thousand  miles  to  the  north  for  the  summer  and  back  again  in 
winter. 

Hummingbirds  are  not  supposed  to  sing,  but  to  use  their  voices  for 
squeaking  when  angry  or  frightened.  However,  I once  had  the  privilege 
of  listening  to  a true  song  by  a hummingbird  on  the  Pacific  Coast.  The 
midget  was  perched  upon  a twig  and  lifted  up  his  voice  with  every 
appearance  of  ecstasy  in  pouring  forth  his  lay.  To  my  uncultured  ear 
this  song  was  a fine,  shrill,  erratic  succession  of  squeaks,  “as  fine  as  a 
cambric  needle,”  said  my  companion. 

The  nest  of  the  hummingbird  is  a most  exquisite  structure ; it  is  about 
three-fourths  of  an  inch  in  diameter  on  the  inside  and  about  half  an  inch 
deep.  It  is,  in  shape,  a symmetrical  cup;  the  outside  is  covered  with 
lichens  to  make  it  exactly  resemble  the  branch  on  which  it  rests;  the 
inside  is  lined  with  the  down  of  plant  seeds  and  plant  fibres.  The  lichens 
are  often  fastened  to  the  outside  with  the  silk  web  of  spiders  or  cater- 
pillars. The  nest  is  usually  saddled  on  a branch  of  a tree  from  io  to  50 
feet  above  the  ground.  The  eggs  are  two  in  number  and  white;  they 
look  like  tiny  beans.  The  young  are  black  and  look,  at  first  glance,  more 
like  insects  than  like  birds. 


LESSON  XXVIII 

The  Hummingbird 

Leading  thought — The  hummingbird  in 
flight  moves  its  wings  so  rapidly  that  we 
cannot  see  them.  It  can  hold  itself  poised 
above  flowers  while  it  thrusts  its  long  beak 
into  them  for  nectar  and  insects. 

Method — Give  the  questions  to  the  pupils 
and  let  them  make  the  observations  when 
they  have  the  opportunity. 

Observations — 1.  Where  do  you  find 
the  hummingbird?  What  flowers  was  it 
visiting?  At  what  time  of  day?  Can  you 
tell  whether  it  is  a hummingbird  or  a hawk- 
moth  which  is  visiting  the  flowers?  At 
what  time  of  day  do  the  hawk-moths 
appear? 

2.  Does  the  hummingbird  ever  come 
to  rest?  Describe  its  actions  while  resting. 

3.  What  are  the  colors  of  the  back,  throat,  breast  and  under  parts? 
How  do  you  distinguish  the  mother  hummingbird  from  her  mate  ? 

4.  How  does  the  hummingbird  act  when  extracting  the  nectar? 
How  does  it  balance  itself  in  front  of  a flower?  Have  you  ever  seen 
hummingbirds  catch  insects  in  the  air?  If  so,  describe  how  they  did  it. 

5.  Describe  the  hummingbird’s  nest.  How  large  is  it  in  diameter? 
Whac  is  the  covering  outside?  With  what  is  it  lined?

THE  RED-WINGED  BLACKBIRD 

Teacher's  Story 

The  blackbirds  are  among  our  earliest  visitors  in  the  spring ; they  come 
in  docks  and  beset  our  leafless  trees  like  punctuation  marks,  meanwhile 
squeaking  like  musical  wheelbarrows.  What  they  are,  where  they  come 
from,  where  they  are  going  and  what  they  are  going  to  do,  are  the  ques- 
tions that  naturally  arise  at  the  sight  of  these  sable  flocks.  It  is  not 
easy  to  distinguish  grackles,  cowbirds  and  rusty  blackbirds  at  a glance, 
but  the  red-wing  proclaims  his  identity  from  afar.  The  bright  red 
epaulets,  margined  behind  with  pale  yellow,  is  a uniform  to  catch  the 
admiring  eye.  The  bird’s  glossy  black  plumage  brings  into  greater  con- 
trast his  bright  decorations.  That  he  is  fully  aware  of  his  beauty,  who 
can  doubt  who  has  seen  him  come  sailing  down  at  the  end  of  his  strong, 
swift  flight,  and  balancing  himself  on  some  bending  reed,  drop  his  long 
tail  as  if  it  were  the  crank  of  his  music  box,  and  holding  both  wings 
lifted  to  show  his  scarlet  decorations,  sing  his  .“quong  quer  ee-ee.”  Little 
wonder  that  such  a handsome,  military  looking  fellow  should  be  able  now 
and  then  to  win  more  than  his  share  of  feminine  admiration.  But  what 
though  he  become  an  entirely  successful  bigamist  or  even  trigamist,  he  has 
proven  himself  to  be  a good  protector  of  each  and  all  of  his  wives  and 
nestlings;  however,  he  often  has  but  one  mate. 

“The  red-wing  flutes  his  O-ka-lee”  is  Emerson’s  graphic  description  of 
the  sweet  song  of  the  red-wing;  he  also  has  many  other  notes.  He  clucks 
to  his  mates  and  clucks  more  sharply  when  suspicious,  and  has  one  alarm 
note  that  is  truly  alarming.  The  male  red-wings  come  from  the  South  in 
March ; they  appear  in  flocks,  often  three  weeks  before  their  mates  arrive. 
The  female  looks  as  though  she  belonged  to  quite  a different  species. 
Although  her  head  and  back  are  black,  the  black  is  decidedly  rusty;  it  is 
quite  impossible  to  describe  her,  she  is  so  inconspicuously  speckled  with 
brown,  black,  whitish  buff  and  orange.  Most  of  us  never  recognize  her 
unless  we  see  her  with  her  spouse.  As  she  probably  does  most  of  the  nest

building,  her  suit  of  salt,  pepper  and  mustard  renders  her  invisible  to  the 
keen  eyes  of  birds  of  prey.  Only  when  she  is  flying,  does  she  show  her 
blackbird  characteristics, — her  tail 
being  long  and  of  obvious  use  as  a 
steering  organ ; and  she  walks  with 
long,  stiff  strides.  The  red-wings 
are  ever  to  be  found  in  and  about 
swamps  and  marshes.  The  nest  is 
built  usually  in  May ; it  is  made  of 
grasses,  stalks  of  weeds  and  is  lined 
with  finer  grass  or  reeds.  It  is 
bulky  and  is  placed  in  low  bushes 
or  among  the  reeds.  The  eggs  are 
pale  blue,  streaked  and  spotted  with 
purple  or  black.  The  young  resem- 
ble the  mother  in  color,  the  males 
being  obliged  to  wait  a year  for 
their  epaulets.  As  to  the  food  of 
the  red-wings  here  in  the  North, 

Mr.  Forbush  says: 

“Although  the  red-wings  almost 
invariably  breed  in  the  swamp  or 
marsh,  they  have  a partiality  for 
open  fields  and  plowed  lands ; how- 
ever, most  of  the  blackbirds  that 
nest  in  the  smaller  swamps  adjacent 
to  farm  lands  get  a large  share  of 
their  food  from  the  farmer’s  fields. 

They  forage  about  the  fields  and 
meadows  when  they  first  come 
north  in  the  spring.  Later,  they 
follow  the  plow,  picking  up  grubs, 
worms  and  caterpillars;  and  should 
there  be  an  outbreak  of  canker- 
worms  in  the  orchard,  the  black- 
birds will  fly  at  least  half  a mile  to 
get  canker-worms  for  their  young. 

Wilson  estimated  that  the  red- 
wings of  the  United  States  would 
in  four  months  destroy  sixteen 
thousand  two  hundred  million  T he  mother  red-wing,  her  nest  and  nestlings . 
larvae.  They  eat  the  caterpillars  Photo  by  a.  a.  Alien, 

of  the  gypsy  moth,  the  forest  tent-caterpillar,  and  other  hairy  larvae.  They 
are  among  the  most  destructive  birds  to  weevils,  click  beetles,  and  wire- 
worms.  Grasshoppers,  ants,  bugs,  and  flies  form  a portion  of  the  red- 
wing’s food.  They  eat  comparatively  little , grain  in  Massachusetts 
although  they  get  some  from  newly  sown  fields  in  spring,  as  well  as 
from  the  autumn  harvest;  but  they  feed  very  largely  on  the  seeds  of 
weeds  and  wild  rice  in  the  fall.  In  the  South  they  join  with  the  bobolink 
in  devastating  the  rice  fields,  and  in  the  West  they  are  often  so  numerous 
as  to  destroy  the  grain  in  the  fields ; but  here  the  good  they  do . far  out- 
weighs the  injury,  and  for  this  reason  they  are  protected  by  law.”

LESSON  XXIX 

The  Red-winged  Blackbird 

Leading  thought — The 
red-winged  blackbird 
lives  in  the  marshes 
where  it  builds  its  nest 
However,  it  comes  over 
to  our  plowed  lands  and 
pastures  and  hdps  the 
farmer  by  destroying 
many  insects  which  in- 
jure the  meadows,  crops 
and  trees. 

Method  — The  obser- 
vations should  be  made 
by  the  pupils  individually  in  the  field.  These  birds  may  be  looked  for  in 
flocks  early  in  the  spring,  but  the  study  should  be  made  in  May  or  June 
when  they  will  be  found  in  numbers  in  almost  any  swamp.  The  questions 
may  be  given  to  the  pupils  a few  at  a time  or  written  in  their  field  note- 
books and  the  answers  discussed  when  discovered. 

Observations — i . How  can  you  distinguish  the  red-winged  blackbird 
from  all  other  blackbirds?  Where  is  the  red  on  his  wings?  Is  there  any 
other  color  besides  black  on  the  wings?  Where?  What  is  the  color  of 
the  rest  of  the  plumage? 

2.  What  is  there  peculiar  in  the  flight  of  the  red-wing?  Is  its  tail 
long  or  short  ? How  does  it  use  its  tail  in  flight  ? What  is  its  position 
when  the  bird  alights  on  a reed? 

3.  What  is  the  song  of  the  red-wing?  Describe  the  way  he  holds  his 
wings  and  tail  when  singing,  balanced  on  a reed  or  some  other  swamp 
grass.  Does  he  show  off  his  epaulets  when  singing?  Why?  What  note 
does  he  give  when  he  is  surprised  or  suspicious  ? When  frightened  ? 

4.  When  does  the  red-wing  first  appear  in  the  spring  ? Does  he  come 
alone  or  in  flocks?  Does  his  mate  come  with  him?  Where  do  the  red- 
wings winter?  In  what  localities  do  the  red-wing  blackbirds  live?  Why 
do  they  live  there?  What  is  the  color  of  the  mother  red-wing?  Would 
you  know  by  her  looks  that  she  was  a blackbird?  What  advantage  is  it 
to  the  pair  that  the  female  is  so  dull  in  color  ? 

5.  At  what  time  do  these  birds  nest ? Where  is  the  nest  built?  Of 
what  material?  How  is  it  concealed?  What  is  the  color  of  the  eggs? 

6.  Do  the  young  birds  resemble  in  color  their  father  or  their  mother? 
Why  is  this  an  advantage? 

7.  Is  the  red-wing  ever  seen  in  fields  adjoining  the  marshes?  What 
is  he  doing  there?  Does  he  walk  or  hop  when  looking  for  food?  What 
is  the  food  of  the  red-wings  ? Do  they  ever  damage  grain  ? Do  they  not 
protect  grain  more  than  they  damage  it? 

8.  What  great  good  do  the  red-wings  do  for  forest  trees?  For 
orchards  ? 

9.  At  what  time  in  the  summer  do  the  red-wings  disappear  from  the 
swamps?  Where  do  they  gather  in  flocks?  Where  is  their  special  feed- 
ing ground  on  the  way  south  for  the  winter?

THE  BALTIMORE  ORIOLE 

Teacher's  Story 

<lI  know  his  name , I know  his  note , 

That  so  with  rapture  takes  my  soul; 

Like  flame  the  gold  beneath  his  throat. 

His  glossy  cope  is  black  as  coal. 

O Oriole,  it  is  the  song 

You  sang  me  from  the  cottonwood, 

Too  young  to  feel  that  I was  young, 

Too  glad  to  guess  if  life  were  good." 

—William  Dean  Howells. 

.NGLING  from  the  slender,  drooping  branches  of 
the  elm  in  winter,  these  pocket  nests  look  like  some 
strange  persistent  fruit;  and,  indeed,  they  are 
the  fruit  of  much  labor  on  the  part  of  the 
oriole  weavers,  those  skilled  artisans  of  the  bird 
world.  Sometimes  the  oriole  “For  the  summer 
voyage  his  hammock  swings”  in  a sapling,  placing 
it  near  the  main  stem  and  near  the  top,  otherwise 
it  is  almost  invariably  hung  at  the  end  of  branches 
and  is  rarely  less  than  twenty  feet  from  the 
ground.  The  nest  is  pocket-shaped,  and  usually 
long,  and  four  and  a half  inches  wide  at  the 
is  the  bottom.  The  top  is  attached  to  forked 
that  the  mouth  or  door  will  be  kept  open  to 
allow  the  bird  to  pass  in  and  out;  when  within,  the  weight  of  the 
bird  causes  the  opening  to  contract  somewhat  and  protects  the  inmate 
from  prying  eyes.  Often  the  pocket  hangs  free  so  that  the  breezes  may 
rock  it,  but  in  one  case  we  found  a nest  with  the  bottom  stayed  to  a twig 
by  guy  lines.  The  bottom  is  much  more  closely  woven  than  the  upper 
part  for  a very  good  reason,  since  the  open  meshes  admit  air  to  the  sitting 
bird.  The  nest  is  lined  with  hair  ^r  other  soft  material,  and  although  this 
is  added  last,  the  inside  of  the  nest  is  woven  first.  The  orioles  like  to 
build  the  framework  of  twine,  and  it  is  marvellous  how  they  will  loop  this 
around  a twig  almost  as  evenly  knotted  as  if  crocheted ; in  and  out  of  this 
net  the  mother  bird  with  her  long,  sharp  beak  weaves  bits  of  wood  fibre, 
strong,  fine  grass  and  scraps  of  weeds.  The  favorite  lining  is  horse  hair, 
which  simply  cushions  the  bottom  of  the  pocket.  Dr.  Detwiler  had  a pet 
oriole  which  built  her  nest  of  his  hair  which  she  pulled  from  his  head ; is 
it  possible  that  orioles  get  their  supply  of  horse  hair  in  a similar  way?  If 
we  put  in  convenient  places,  bright  colored  twine  or  narrow  ribbons  the 
orioles  will  weave  them  into  the  nest,  but  the  strings  should  not  be  long, 
lest  the  birds  become  entangled.  If  the  nest  is  strong  the  birds  will  use 
it  a second  year. 

That  Lord  Baltimore  found  in  new  America  a bird  wearing  his 
colors,  must  have  cheered  him  greatly;  and  it  is  well  for  us  that  this 
brilliant  bird  brings  to  our  minds  kindly  thoughts  of  that  tolerant,  high- 
minded  English  nobleman.  The  oriole’s  head,  neck,  throat  and 
part  of  the  back  are  black;  the  wings  are  black  but  the  feathers  are 
margined  with  white;  the  tail  is  black  except  that  the  ends  of  the  outer 
feathers  are  yellow;  all  the  rest  of  the  bird  is  golden  orange,  a luminous

it  looks  olive-brown; 
the  rump,  breast,  and 
under  parts  are  yel- 
low but  by  no  means 
showy.  The  advan- 
tage of  these  quiet 
colors  to  the  mother 
bird  is  obvious  since  it 
is  she  that  makes  the 
nest  and  sits  in  it 
without  attracting  at- 
tention to  its  location. 
In  fact,  when  she  is 
sitting , her  brilliant 
mate  places  himself 
far  enough  away  to 
distract  the  atten- 
tion of  meddlers,  yet 
near  enough  for  her 
to  see  the  flash  of  his 
breast  in  the  sunshine 
and  to  hear  his  rich  and  cheering  song.  He  is  a good  spouse  and 
brings  her  the  materials  for  the  nest  which  she  weaves  in,  hanging 
head  downward  from  a twig  and  using  her  long  sharp  beak  for  a 
shuttle.  And  his  glorious  song  is  for  her  alone;  some  hold  that  no  two 
orioles  have  the  same  song ; I know  of  two  individuals  at  least  whose 
songs  were  sung  by  no  other  birds;  one  gave  a phrase  from  the  Wald- 
vogel’s  song  in  Sigfried;  the  other  whistled  over  and  over,  “Sweet 
birdie,  hello,  hello.”  The  orioles  can  chatter  and  scold  as  well  as  sing. 

The  oriole  is  a brave  defender  of  his  nest  and  a most  devoted  father, 
working  hard  to  feed  his  ever  hungry  nestlings ; we  can  hear  these  hollow 
mites  peeping  for  more  food,  “Tee  dee  dee,  Tee  dee  dee”,  shrill  and  con- 
stant, if  we  stop  for  a moment  under  the  nest  in  June.  The  young  birds 
dress  in  the  safe  colors  of  the  mother,  the  males  not  donning  their  bright 
plumage  until  the  second  year.  A brilliant  colored  fledgling  would  not 
live  long  in  a world  Tyhere  sharp  eyes  are  in  constant  quest  for  little  birds 
to  fill  empty  stomachs. 

The  food  of  the  oriole  places  it  among  our  most  beneficial  birds,  since 
it  is  always  ready  to  cope  with  the  hairy  caterpillars  avoided  by  most 
birds;  it  has  learned  to  abstract  the  caterpillar  from  his  spines  and  is  thus 
able  to  swallow  him  minus  his  “whiskers.”  The  orioles  are  waging  a 
great  war  against  the  terrible  brown-tail  and  gipsy  moths  in  New  England ; 
they  also  eat  click  beetles  and  many  other  noxious  insects.  Once  when 
we  were  breeding  big  caterpillars  in  the  Cornell  insectary,  an  oriole  came 
in  through  the  open  windows  of  the  greenhouse,  and  thinking  he  had 
found  a bonanza  proceeded  to  work  it,  carrying  off  our  precious  crawlers 
before  we  discovered  what  he  was  at. 

The  orioles  winter  in  Central  America  and  give  us  scarcely  four  months 
of  their  company.  They  do  not  usually  appear  before  May  and  leave  in 
early  September.

LESSON  XXX 
The  Oriole 

Leading  thought — The  oriole  is  the  most  skillful  of  all  our  bird  archi- 
tects. It  is  also  one  of  our  prized  song  birds  and  is  very  beneficial  to  the 
farmer  and  fruit  grower  because  of  the  insect  pests  which  it  destroys. 

Method — Begin  during  winter  or  early  spring  with  a study  of  the  nest, 
which  may  be  obtained  from  the  elms  of  the  roadsides.  During  the  first 
week  in  May,  give  the  questions  concerning  the  birds  and  their  habits. 
Let  the  pupils  keep  the  questions  in  their  note-books  and  answer  them 
when  they  have  opportunity.  The  observations  should  be  summed  up 
once  a week. 

Observations  by  pupils — 1.  Where  did  you  find  the  nest?  On  what 
species  of  tree?  Was  it  near  the  trunk  of  the  tree  or  the  tip  of  the 
branch  ? 

2.  What  is  the  shape  of  fhe  nest?  How  long  is  it?  How  wide?  Is 
the  opening  as  large  as  the  bottom  of  the  nest?  How  is  it  hung  to  the 
twigs  so  that  the  opening  remains  open  and  does  not  pull  together  with 
the  weight  of  the  bird  at  the  bottom  ? Is  the  bottom  of  the  nest  stayed 
to  a twig  or  does  it  hang  loose  ? 


128 


Handbook  of  Nature-Study 


3.  With  what  material  and  how  is  the  nest  fastened  to  the  branches? 
Of  what  material  is  the  outside  made ? How  is  it  woven  together?  Is  it 
more  loosely  woven  at  the  top  than  at  the  bottom  ? How  many  kinds  of 
material  can  you  find  in  the  outside  of  the  nest  ? 

4.  With  what  is  the  nest  lined?  How  far  up  is  it  lined?  With  what 
tool  was  the  nest  woven  ? If  you  put  out  bright  colored  bits  of  ribbon  and 
string  do  you  think  the  orioles  will  use  them?  Why  should  you  not  put 
out  long  strings? 

5.  At  what  date  did  you  first  see  the  Baltimore  oriole?  Why  is  it 

called  the  Baltimore  oriole?  How  many  other  names  has  it?  Describe 
in  the  following  way  the  colors  of  the  male  oriole:  top  of  head,  back, 

wings,  tail,  throat,  breast,  under  parts.  What  are  the  colors  of  his  mate? 
How  would  it  endanger  the  nest  and  nestlings  if  the  mother  bird  were  as 
bright  colored  as  the  father  bird? 

6.  Which  weaves  the  nest,  the  father  or  the  mother  bird?  Does 
the  former  assist  in  any  way  in  nest  building? 

7.  Where  does  the  father  bird  stay  and  what  does  he  do  while  the 
mother  bird  is  sitting  on  the  eggs? 

8.  What  is  the  oriole’s  song?  Has  he  more  than  one  song?  What 
other  notes  has  he?  After  the  young  birds  hatch  does  the  father  bird 
help  take  care  of  them? 

9.  By  the  middle  of  June  the  young  birds  are  usually  hatched  and  if 
you  know  where  an  oriole  nest  is  hung,  listen  and  describe  the  call  of  the 
nestlings  for  food. 

10.  Which  parent  do  the  young  birds  resemble  in  their  colors?  Why 
is  this  a benefit? 

11.  What  is  the  oriole’s  food?  How  is  the  oriole  of  benefit  to  us  in 
ways  which  other  birds  are  not  ? 

12.  Do  the  orioles  use  the  same  nest  two  years  in  succession?  How 
long  does  the  oriole  stay  in  the  North?  Where  does  it  spend  its  winters? 


“Hush!  'tis  he! 

My  oriole,  my  glance  of  summer  fire. 

Is  come  at  last,  and,  ever  on  the  watch, 

Twitches  the  packthread  I had  lightly  wound 
About  the  bough  to  help  his  housekeeping, — - 
Twitches  and  scouts  by  turns,  blessing  his  luck. 

Yet  fearing  me  who  laid  it  in  his  way, 

Nor,  more  than  wiser  we  in  our  affairs. 

Divines  the  Providence  that  hides  and  helps. 

Heave,  ho!  Heave,  ho!  he  whistles  as  the  twine 
Slackens  its  hold;  once  more,  now!  and  a flash 
Lightens  across  the  sunlight  to  the  elm 
Where  his  mate  dangles  at  her  cup  of  felt."

THE  CROW 

Teacher’s  Story 

HOREAU  says:  “What  a perfectly  New  England 
sound  is  this  voice  of  the  crow!  If  you  stand  still 
anywhere  in  the  outskirts  of  the  town  and  listen,  this 
is  perhaps  the  sound  which  you  will  be  most  sure  to 
hear,  rising  above  all  sounds  of  human  industry  and 
leading  your  thoughts  to  some  far-away  bay  in  the 
woods.  The  bird  sees  the  white  man  come  and  the 
Indian  withdraw,  but  it  withdraws  not.  Its  untamed 
voice  is  still  heard  above  the  tinkling  of  the  forge. 
It  sees  a race  pass  away,  but  it  passes  not  away. 
It  remains  to  remind  us  of  aboriginal  nature.” 

The  crow  is  probably  the  most  intelligent  of  all  our  native  birds.  It  is 
quick  to  learn  and  clever  in  action,  as  many  a farmer  will  testify  who  has 
tried  to  keep  it  out  of  com  fields  with  various  devices,  the  harmless 
character  of  which  the  crow  soon  understood  perfectly.  Of  all  our  birds, 
this  one  has  the  longest  list  of  virtues  and  of  sins,  as  judged  from  our 
standpoint;  but  we  should  listen  to  both  sides  of  the  case  before  we  pass 
judgment.  I find  with  crows,  as  with  people,  I like  some  more  than  I do 
others.  I do  not  like  at  all  the  cunning  old  crow  which  steals  the  suet  I 
put  on  the  trees  in  winter  for  the  chickadees  and  nuthatches;  and  I have 
hired  a boy  with  a shotgun  to  protect  the  eggs  and  nestlings  of  the  robins 
and  other  birds  in  my  neighborhood  from  the  ravages  of  one  or  two  cruel

old  crows  that  have  developed  the  nest-hunting  habit.  On  the  other 
hand,  I became  a sincere  admirer  of  a crow  flock  which  worked  in  a field 
close  to  my  country  home,  and  I have  been  the  chosen  friend  of  several 
tame  crows  who  were  even  more  interesting  than  they  were  mischievous. 

The  crow  is  larger  than  any  other  of  our  common  blackbirds;  the 
northern  raven  is  still  larger,  but  is  very  rarely  seen.  Although  the 
crow’s  feathers  are  black,  yet  in  the  sunlight  a beautiful  purple  iridescence 
plays  over  the  plumage,  especially  about  the  neck  and  back;  it  has  a 
compact  but  not  ungraceful  body,  and  long,  powerful  wings;  its  tail  is 
medium  sized  and  is  not  notched  at  the  end ; its  feet  are  long  and  strong ; 
the  track  shows  three  toes  directed  forward  and  one  long  one  directed 
backward.  The  crow  does  not  sail  through  the  air  as  does  the  hawk,  but 
progresses  with  an  almost  constant  flapping  of  the  wings.  Its  beak  is 
very  strong  and  is  used  for  tearing  the  flesh  of  its  prey  and  for  defense, 
and  in  fact,  for  almost  anything  that  a beak  could  be  used  for;  its  eye  is 
all  black  and  is  very  keen  and  intelligent.  When  hunting  for  food  in  the 
field,  it  usually  walks,  but  sometimes  hops.  The  raven  and  the  fish  crows 
are  the  nearest  relatives  of  the  American  crow,  and  next  to  them  the 
jays.  We  should  hardly  think  that  the  bluejay  and  the  crow  were 
related  to  look  at  them,  but  when  we  come  to  study  their  habits,  much  is 
to  be  found  in  common. 

The  crow’s  nest  is  usually  very  large;  it  is  made  of  sticks,  of  grape 
vines  and  bark,  sod,  horse-hair,  moss  and  grasses.  It  is  placed  in  trees  or 
in  tall  bushes  rarely  less  than  twenty  feet  from  the  ground.  The  eggs  are 
pale  bluish  green  or  nearly  white  with  brownish  markings.  The  young 
crows  hatch  in  April  or  May.  Both  parents  are  devoted  to  the  care  of  the 
young,  and  remain  with  them  during  most  of  the  summer.  I have  often 
seen  a mother  crow  feeding  her  young  ones  which  were  following  her  with 
obstreperous  caws,  although  they  were  as  large  as  she. 

While  the  note  of  the  crow  is  harsh  when  close  at  hand,  it  has  a musical 
quality  in  the  distance.  Mr.  Mathews  says:  “The  crow  when  he  sings 

is  nothing  short  of  a clown ; he  ruffles  his  feathers,  stretches  his  neck,  like 
a cat  with  a fish  bone  in  her  throat,  and  with  a most  tremendous  effort 
delivers  a series  of  hen-like  squawks.”  But  aside  from  his  caw,  the  crow 
has  some  very  seductive  soft  notes.  I have  held  long  conversations  with 
two  pet  crows,  talking  with  them  in  a high,  soft  tone  and  finding  that  they 
answered  readily  in  a like  tone  in  a most  responsive  way.  I have  also 
heard  these  same  tones  among  the  wild  crows  when  they  were  talking 
together;  one  note  is  a gutteral  tremolo,  most  grotesque. 

Crows  gather  in  flocks  for  the  winter ; these  flocks  number  from  fifty  to 
several  hundred  individuals,  all  having  a common  roosting  place,  usually 
in  pine  or  hemlock  forests  or  among  other  evergreens.  They  go  out  from 
these  roosts  during  the  day  to  get  food,  often  making  a journey  of  many 
miles.  During  the  nesting  season  they  scatter  in  pairs  and  do  not  gather 
again  in  flocks  until  the  young  are  fully  grown. 

When  crows  are  feeding  in  the  fields  there  is  usually,  if  not  always,  a 
sentinel  posted  on  some  high  point  so  that  he  can  give  warning  of  danger. 
This  sentinel  is  always  an  experienced  bird  and  is  keen  to  detect  a 
dangerous  from  a harmless  intruder.  I once  made  many  experiments 
with  these  sentinels ; I finally  became  known  to  those  of  a particular  flock 
and  I was  allowed  to  approach  within  a few  yards  of  where  the  birds  were 
feeding,  a privilege  not  accorded  to  any  other  person  in  the  neighborhood. 


Bird  Study

The  crow  is  a general  feeder  and  will  eat  almost  any  food ; generally, 
however,  it  finds  its  food  upon  the  ground.  The  food  given  to  nestlings 
is  very  largely  insects,  and  many  pests  are  thus  destroyed.  The  crows 
damage  the  farmer  by  pulling  the  sprouting  corn  and  by  destroying  the 
eggs  and  young  of  poultry.  They  also  do  much  harm  by  destroying  the 
eggs  and  nestlings  of  our  native  birds  which  are  beneficial  to  the  farmer; 
they  also  do  some  harm  by  distributing  the  seeds  of  poison  ivy  and  other 
noxious  plants.  All  these  must  be  set  down  in  the  account  against  the 
crow,  but  on  the  credit  side  must  be  placed  the  fact  that  it  does  a tremen- 
dous amount  of  good  work  for  the  farmer  by  eating  injurious  insects, 
especially  the  grubs  and  cut-worms  which  work  in  the  ground,  destroying 
the  roots  of  grasses  and  grains.  It  also  kills  many  mice  and  other  rodents 
which  are  destructive  to  crops. 

The  best  method  of  preventing  crows  from  taking  sprouting  com  is  to 
tar  the  seed  com,  which  is  planted  around  the  edge  of  the  field. 

If  any  of  the  pupils  in  your  school  have  had  any  experience  with  tame 
crows  they  will  relate  interesting  incidents  of  the  love  of  the  crow  for  glit- 
tering objects.  I once  knew  a tame  crow  which  stole  all  of  the  thimbles 
in  the  house  and  buried  them  in  the  garden ; he  would  watch  to  see  when 
a thimble  was  laid  aside  when  the  sewing  was  dropped,  and  would  seize  it 
almost  immediately.  This  same  crow  persisted  in  taking  the  clothes-pins 
off  the  line  and  burying  them,  so  that  he  was  finally  imprisoned  on  wash- 
days. He  was  fond  of  playing  marbles  with  a little  boy  of  the  family. 
The  boy  would  shoot  a marble  into  a hole  and  then  Billy,  the  crow,  would 
take  a marble  in  his  beak  and  drop  it  into  the  hole.  The  bird  understood 
the  game  perfectly  and  was  highly  indignant  if  the  boy  took  his  turn  and 
made  shots  twice  in  succession.

LESSON  XXXI 
The  Crow 

Leading  thought — The  crow  has  the  keenest  intelligence  of  any  of  our 
common  birds.  It  does  good  work  for  us  and  also  does  damage.  We 
should  study  its  ways  before  we  pronounce  judgment,  for  in  some  locali- 
ties it  may  be  a true  friend  and  in  others  an  enemy. 

Methods — This  work  should  begin  in  winter  with  an  effort  on  the  part 
of  the  boys  to  discover  the  food  of  the  crows  while  snow  is  on  the  ground. 
This  is  a good  time  to  study  their  habits  and  their  roosts.  The  nests  are 
also  often  found  in  winter,  although  usually  built  in  evergreens.  The 
nesting  season  is  in  early  April,  and  the  questions  about  the  nests  should 
be  given  then.  Let  the  other  questions  be  given  when  convenient.  The 
flight,  the  notes,  the  sentinels,  the  food,  the  benefit  and  damage  may  all 
be  taken  as  separate  topics. 

The  following  topics  for  essays  should  be  given  to  correlate  with  work 
in  English:  “What  a pet  crow  of  my  acquaintance  did;”  “Evidences  of 

crow  intelligence;”  “A  plea  a crow  might  make  in  self-defence  to  the 
farmer  who  wished  to  shoot  him ;”  ‘ ‘The  best  methods  of  preventing  crows

THE  CARDINAL  GROSBEAK 
Teacher's  Story 

There  never  lived  a Lord  Cardinal  who 
possessed  robes  ol  state  more  brilliant  in 
color  than  the  plumage  of  this  bird.  By 
the  way,  I wonder  how  many  of  us  ever 
think  when  we  see  the  peculiar  red,  called 
cardinal,  that  it  gained  its  name  from  the 
dress  of  this  high  tunctionaryof  the  church  ? 
The  cardinal  grosbeak  is  the  best  name  for 
the  redbird  because  that  describes  it 
exactly,  both  as  to  its  color  and  its  chief 
characteristic,  since  its  beak  is  thick  and 
large;  the  beak  is  also  red,  which  is  a rare 
color  in  beaks,  and  in  order  to  make  its 
redness  more  emphatic  it  is  set  in  a frame 
of  black  feathers.  The  use  of  such  a large 
beak  is  unmistakable,  for  it  is  strong 
enough  to  crush  the  hardest  of  seed  shells 
or  to  crack  the  hardest  and  driest  of 
grains. 

11  What  cheer!  What  cheer! 

That  is  the  grosbeak’s  way, 

With  his  sooty  +ace  and  ins  coat  of  red ” 

sings  Maurice  Thompson.  But  besides 
the  name  given  above,  this  bird  has  been  called  in  different  localities 
the  redbird,  Virginia  redbird,  crested  redbird,  winter  redbird,  Virginia 
nightingale,  the  red  corn-cracker;  but  it  remained  for  James  Lane 
Allen  to  give  it  another  name  in  his  masterpiece,  “The  Kentucky 
Cardinal.” 

The  cardinal  is  a trifle  smaller  than  the  robin  and  is  by  no  means  slim 
and  graceful,  like  the  catbird  or  the  scarlet  tanager,  but  is  quite  stout  and 
is  a veritable  chunk  of  brilliant  color  and  bird  dignity.  The  only  other 
bird  that  rivals  him  in  redness  is  the  scarlet  tanager  which  has  black 
wings;  the  summer  tanager  is  also  a red  bird,  but  is  not  so  vermilion  and 
is  more  slender  and  lacks  the  crest.  The  cardinal  surely  finds  his  crest 
useful  in  expressing  his  emotions;  when  all  is  serene,  it  lies  back  flat  on 
the  head,  but  with  any  excitement,  whether  of  joy  or  surprise  or  anger,  it 
lifts  until  it  is  as  peaked  as  an  old-fashioned  nightcap.  The  cardinal’s 
mate  is  of  quiet  color;  her  back  is  greenish  gray  and  breast  buffy,  while 
her  crest,  wings  and  tail  reflect  in  faint  ways  the  brilliancy  of  his  costume. 

The  redbird’s  song  is  a stirring  succession  of  Syllables  uttered  in  a rich, 
ringing  tone,  and  may  be  translated  in  a variety  of  ways.  I have  heard 
him  sing  a thousand  times  “tor-re’-do,  tor-re’-do,  tor-re’-do,”  but  Dr. 
Dawson  has  heard  him  sing  “che’-pew,  che’-pew,  we’-woo,  we ’-woo;” 
“bird-ie,  bird-ie,  bird-ie;  tschew,  tschew,  tschew;”  and  “chit-e-kew, 
chit-e-kew;  he-weet-  he-weet.”  His  mate  breaks  the  custom  of  other 
birds  of  her  sex  and  sings  a sweet  song,  somewhat  softer  than  his.  Both 
birds  utter  a sharp  note  “tsip,  tsip.” 

The  nest  is  built  in  bushes,  vines  or  low  trees,  often  in  holly,  laurel  or 
other  low  evergreens,  and  is  rarely  more  than  six  or  eight  feet  above  the

ground.  It  is  made  of  twigs,  weed  stems,  tendrils,  the  bark  of  the  grape 
vine  and  coarse  grass;  it  is  lined  with  fine  grass  and  rootlets;  it  is  rather 
loosely  constructed  but  firm  and  is  well  hidden,  for  it  causes  these  birds 
great  anguish  to  have  their  nest  discovered.  Three  or  four  eggs  are  laid, 
which  are  bluish  white  or  grayish,  dully  marked  with  brown.  The  father 
cardinal  is  an  exemplary  husband  and  father;  he  cares  for  and  feeds  his 
mate  tenderly  and  sings  to  her  gloriously  while  she  is  sitting;  and  he 
works  hard  catching  insects  for  the  nestlings.  He  is  also  a brave  defender 
of  his  nest  and  will  attack  any  intruder,  however  large,  with  undaunted 
courage.  The  fledglings  all  have  the  dull  color  of  the  mother  and  have 
dark-colored  bills.  Their  dull  color  protects  the  young  birds  from  the 
keen  eyes  of  their  enemies  while  they  are  not  yet  able  to  take  care  of 
themselves.  If  the  male  fledglings  were  the  color  of  their  father,  probably 
not  one  would  escape  a tragic  death.  While  the  mother  bird  is  hatching 
the  second  brood  the  father  keeps  the  first  brood  with  him  and  cares  for 
them ; often  the  whole  family  remains  together  during  the  winter,  making 
a small  flock.  However,  the  flocking  habit  is  not  characteristic  of  these 
birds,  and  we  only  see  them  in  considerable  numbers  when  the  exigencies 
of  seeking  food  in  the  winter  naturally  bring  them  together. 

The  car  dinals  are  fond  of  the  shrubbery  and  thickets  of  river  bottoms, 
near  grain  fields,  or  where  there  is  plenty  of  wild  grass,  and  they  only  visit 
our  premises  when  driven  to  us  by  winter  hunger.  Their  food  consists  of 
the  seeds  of  rank  weeds,  com,  wheat,  rye,  oats,  beetles,  grasshoppers, 
flies,  and  to  some  extent,  wild  and  garden  berries ; but  they  never  occur  in 
sufficient  numbers  to  be  a menace  to  our  crops.  The  cardinals  may  often 
be  seen  in  the  com  fields  after  the  harvest,  and  will  husk  an  overlooked  ear 
of  corn  and  crack  the  kernels  with  their  beaks  in  a most  dexterous  man- 
ner. During  the  winter  we  may  coax  them  to  our  grounds  by  scattering 
com  in  some  place  not  frequented  by  cats;  thus,  we  may  induce  them  to 
nest  near  us,  since  the  cardinal  is  not  naturally  a migrant  but  likes  to  stay 
in  one  locality  summer  and  winter.  It  has  been  known  to  come  as  far 
north  as  Boston  and  southern  New  York,  but  it  is  found  in  greatest  num- 
bers in  our  Southern  States.  Many  nestlings  were  formerly  taken,  to  ship 
in  cages  to  Europe,  but  the  National  Association  for  Bird  Protection  has 
put  a stop  to  this.  In  Ohio,  no  cardinal  is  allowed  to  be  caged,  and  this 
same  law  should  protect  this  beautiful  bird  in  every  Southern  state,  since 
it  does  not  live  long  or  happily  in  confinement.  The  cardinal’s  song  is  not 
at  its  best  in  a cage,  but  as  the  poet  Naylor  says: 

“ Along  the  dust-white  river  road. 

The  saticy  redbird  chirps  and  trills; 

His  liquid  notes  resound  and  rise 
Until  they  meet  the  cloudless  skies. 

And  echo  o'er  the  distant  hills.” 

LESSON  XXXII 
The  Cardinal  Grosbeak 

Leading  thought — The  cardinal  is  the  most  brilliantly  colored  of  all  our 
birds  and  because  of  its  color  and  song,  it  has  been  destroyed  by  thousands 
as  cage  birds.  We  should  seek  to  preserve  it  as  a beautiful  ornament  to 
our  groves  and  grounds.

Methods — This  work  must  be  done  by  personal  observation  in  the  field. 
The  field  notes  should  be  discussed  in  school.  The  effect  of  the  whole 
lesson  should  be  to  stimulate  an  interest  in  protecting  these  beautiful 
birds.  If  possible,  send  for  outline  figures  of  the  cardinal  for  the  children 
to  color ; these  outlines  may  be  had  at  the  cost  of  fifteen  cents  per  dozen 
from  the  Audubon  Society,  141  Broadway,  New  York  City. 

Observations — 1.  Do  you  know  the  cardinal?  Why  is  it  so  called? 

2.  How  many  names  do  you  know  for  this  bird? 

3.  Is  the  cardinal  as  large  as  the  robin?  Is  it  graceful  in  shape  or 
stout? 

4.  Is  there  any  color  except  red  upon  it  ? If  so,  where  ? 

5.  What  other  vividly  red  birds  have  we  and  how  can  we  distinguish 
them  from  the  cardinal  ? 

6.  Describe  the  cardinal’s  crest  and  how  it  looks  when  lifted.  Why 
do  you  think  it  lifts  it  ? 

7.  Describe  its  beak  as  to  color,  shape  and  size.  What  work  is  such 
a heavy  beak  made  for? 

8.  Is  the  cardinal’s  mate  the  same  color  as  he  ? Describe  the  color  of 
her  head,  back,  wings,  tail,  breast. 

9.  Can  you  imitate  the  cardinal’s  song?  What  words  do  you  think 
he  seems  to  sing?  Does  his  mate  sing  also ? Is  it  usual  for  mother  birds 
to  sing?  What  other  notes  besides  songs  do  you  hear  him  utter? 

10.  Where  does  the  cardinal  usually  build  its  nest?  How  high  from 

the  ground  ? Of  what  materials  ? Is  it  compact  or  bulky  ? How  many 

eggs  and  what  are  their  colors? 

1 1 . How  does  the  father  bird  act  while  his  mate  is  brooding  ? How 
does  he  help  take  care  of  the  young  in  the  nest  ? 

12.  How  do  the  fledglings  differ  in  color  from  their  father?  From 
their  mother?  Of  what  use  to  the  young  birds  is  their  sober  color?

Of  umbrel  leaves  above  them  bent; 

Where  oft  was  shifting  light  and  shade 
The  blue-eyed  ivy  wildly  strayed; 

The  Solomon’s  seal,  in  graceful  play, 

Swung  where  the  straggling  sunlight  lay 
The  same  as  when  I earliest  heard 
The  Cardinal  bird.”

GEESE 
Teacher's  Story 

called  a goose  should  be  considered  most  com- 
plimentary, for  of  all  the  birds  the  goose  is  probably 
the  most  intelligent.  An  observant  lady  who 
keeps  geese  on  her  farm  assures  me  that  no  animal, 
not  even  dog  or  horse,  has  the  intelligence  of  the 
goose.  She  says  that  these  birds  learn  a lesson 
after  a few  repetitions,  and  surely  her  geese  were 
patterns  of  obedience.  While  I was  watching  them 
one  morning,  they  started  for  the  brook  via  the 
com  field;  she  called  to  them  sharply,  “No,  no, 
way!”  They  stopped  and  conferred;  she  spoke 
again  and  they  waited,  looking  at  her  as  if  to  make  up  their  minds  to  this 
exercise  of  self-sacrifice ; but  when  she  spoke  the  third  time  they  left  the 
com  field  and  took  the  other  path  to  the  brook.  She  could  bring  her 
geese  into  their  house  at  any  time  of  day  by  calling  to  them,  “Home, 
home!”  As  soon  as  they  heard  these  words,  they  would  start  and  not 
stop  until  the  last  one  was  housed. 

In  ancient  Greece  maidens  made  pets  of  geese;  and  often  there  was 
such  a devotion  between  the  bird  and  girl  that  when  the  latter  died  her 
statue  with  that  of  the  goose  was  carved  on  her  burial  tablet.  The 
loyalty  of  a pet  goose  came  under  the  observation  of  Miss  Ada  Georgia. 
A lone  gander  was  the  special  pet  of  a small  boy  in  Elmira,  N.  Y.,  who 
took  sole  care  of  him.  The  bird  obeyed  commands  like  a dog  but  would 
never  let  his  little  master  out  of  his  sight  if  he  could  avoid  it ; occasionally 
he  would  appear  in  the  school  yard,  where  the  pupils  would  tease  him  by 
pretending  to  attack  his  master  at  the  risk  of  being  whipped  with  his 
wings  so  severely  that  it  was  a test  of  bravery  among  the  boys  to  so  chal- 
lenge him.  His  fidelity  to  his  master  was  extreme;  once  when  the  boy 


Bird  Study

was  ill  in  bed,  the  bird  wandered  about  the  yard  honking  disconsolately 
and  refused  to  eat ; he  was  driven  to  the  side  of  the  house  where  his  mas- 
ter could  look  from  the  window  and  he  immediately  cheered  up,  took  his 
food  and  refused  to  leave  his  post  beneath  the  window  while  the  illness, 
lasted. 

The  goose  is  a stately  bird  whether  on  land  or  water;  its  long  legs  give 
it  good  proportions  when  walking,  and  the  neck  being  so  much  longer 
than  that  of  the  duck  gives  an  appearance  of  grace  and  dignity.  The 
duck  on  the  other  hand  is  beautiful  only  when  on  the  water  or  on  the 
wing;  -its  short  legs,  placed  far  back  and  far  out  at  the  sides,  make  it  a 
most  ungraceful  walker.  The  beak  of  the  goose  is  harder  in  texture  and 
is  not  flat  like  the  duck’s;  no  wonder  the  bird  was  a favorite  with  the 
ancient  Greeks  for  the  high  ridge  from  the  beak  to  the  forehead  resembles 
much  the  famous  Grecian  nose.  The  plumage  of  geese  is  very  beautiful 
and  abundant  and  for  this  reason  they  are  profitable  domestic  birds. 
The  “picking”  occurs  late  in  summer  when  the  feathers  are  nearly  ready 
to  be  molted;  at  this  time  the  geese  flap  their  wings  often  and  set 
showers  of  loose  feathers  flying.  A stocking  or  a bag  is  slipped  over  the 
bird’s  head  and  she  is  turned  breast  side  up,  with  her  head  firmly  between 
the  knees  or  under  the  arm  of  the  picker.  The  tips  of  the  feathers  are 
seized  with  the  fingers  and  come  out  easily;  only  the  breast,  the  under 
parts  and  the  feathers  beneath  the  wings  are  plucked.  Geese  do  not  seem 
to  suffer  while  being  plucked  except  through  the  temporary  inconvenience 
and  ignominy  of  having  their  heads  thrust  into  a bag;  it  hurts  their 
dignity  more  than  their  bodies. 

The  wings  of  geese  are  very  large  and  beautiful ; although  our  domestic 
geese  have  lost  their  powers  of  flight  to  a great  extent,  yet  they  often 
stretch  their  wings  and  take  little  flying  hops,  teetering  along  as  if  they 
can  scarcely  keep  to  earth;  this  must  surely  be  reminiscent  of  the  old 
instinct  for  traveling  in  the  skies.  The  tail  of  the  goose  is  a half  circle 
and  is  spread  when  flying;  although  it  is  short,  it  seems  to  be  sufficiently 
long  to  act  as  a rudder.  The  legs  of  the  goose  are  much  longer  than  those 
of  the  duck;  they  are  not  set  so  far  back  toward  the  rear  of  the  body,  and, 
therefore,  the  goose  is  the  much  better  runner  of  the  two.  The  track 
made  by  the  goose’s  foot  is  a triangle  with  two  scallops  on  one  side  made 
by  the  webs  between  the  three  front  toes ; the  hind  toe  is  placed  high  up ; 
the  foot  and  the  unfeathered  portion  of  the  leg,  protected  by  scales,  are 
used  as  oars  when  the  bird  is  swimming.  When  she  swims  forward 
rapidly,  her  feet  extend  out  behind  her  and  act  on  the  principle  of  a 
propeller;  but  when  swimming  around  in  the  pond  she  uses  them  at 
almost  right  angles  to  the  body.  Although  they  are  such  excellent  oars 
they  are  also  efficient  on  land;  although  when  running,  her  body  may 
waddle  somewhat,  her  head  and  neck  are  held  aloft  in  stately  dignity. 

The  Toulouse  are  our  common  gray  geese;  the  Embdens  are  pure 
white  with  orange  bill  and  bright  blue  eyes.  The  African  geese  h ave  a 
black  head  with  a large  black  knob  on  the  base  of  the  black  bill ; the  neck 
is  long,  snakelike,  light  gray,  with  a dark  stripe  down  the  back;  the  wings 
and  tail  are  dark  gray;  there  is  a dewlap  at  the  throat.  The  brown 
Chinese  geese  have  also  a black  beak  and  a black  knob  at  the  base  of  the 
bill.  The  neck  is  light  brown  with  a dull  yellowish  stripe  down  the  neck. 
The  back  is  dark  brown,  breast,  wings  and  tail  grayish  brown.  The  white 
Chinese  are  shaped  like  the  brown  Chinese  but  the  knob  and  bill  are 
orange  and  the  eyes  light  blue.

The  Habits  of  Geese 

Geese  are  monogamous  and  are  loyal  to  their  mates.  Old-fashioned 
people  declare  that  they  choose  their  mates  on  Saint  Valentine’s  Day,  but 
this  is  probably  a pretty  myth;  when  once  mated,  the  pair  live  together 
year  after  year  until  one  dies ; an  interesting  instance  of  this  is  one  of  the 
traditions  in  my  own  family.  A fine  pair  of  geese  belonging  to  my 
pioneer  grandfather  had  been  mated  for  several  years  and  had  reared 
handsome  families;  but  one  spring  a conceited  young  gander  fell  in  love 
with  the  old  goose,  and  as  he  was  young  and  lusty,  he  whipped  her  legiti- 
mate lord  and  master  and  triumphantly  carried  her  away,  although  she 
was  manifestly  disgusted  with  this  change  in  her  domestic  fortunes.  The 
old  gander  sulked  and  refused  to  be  comforted  by  the  blandishments  of 
any  young  goose  whatever.  Later  the  old  pair  disappeared  from  the 
farmyard  and  the  upstart  gander  was  left  wifeless.  It  was  inferred  that 
the  old  couple  had  run  away  with  each  other  into  the  encompassing 
wilderness  and  much  sympathy  was  felt  for  them  because  of  this  sacrifice 
of  their  lives  for  loyalty.  However,  this  was  misplaced  sentiment,  for 
later  in  the  summer  the  happy  pair  was  discovered  in  a distant  “slashing” 
with  a fine  family  of  goslings  and  were  all  brought  home  in  triumph. 
The  old  gander,  while  not  able  to  cope  with  his  rival,  was  still  able  to 
trounce  any  of  the  animal  marauders  which  approached  his  home  and 
family. 

The  goose  lines  her  nest  with  down  and  the  soft  feathers  which  she 
plucks  from  her  breast.  The  gander  is  very  devoted  to  his  goose  while 
she  is  sitting;  he  talks  to  her  in  gentle  tones  and  is  fierce  in  her  defence. 
The  eggs  are  about  twice  as  large  as  those  of  the  hen  and  have  the  ends 
more  rounded.  The  period  of  incubation  is  four  weeks.  The  goslings 
are  beautiful  little  creatures,  covered  with  soft  down,  and  have  large, 
bright  eyes.  The  parents  give  them  most  careful  attention  from  the  first. 
One  family  which  I studied  consisted  of  the  parents  and  eighteen  goslings. 
The  mother  was  a splendid  African  bird;  she  walked  with  dignified  step, 
her  graceful  neck  assuming  serpentine  curves ; and  she  always  carried  her 
beak  “lifted,”  which  gave  her  an  appearance  of  majestic  haughtiness. 
The  father  was  just  a plebeian  white  gander,  probably  of  Embden  descent 
but  he  was  a most  efficient  protector.  The  family  always  formed  a 
procession  in  going  to  the  creek,  the  majestic  mother  at  the  head,  the 
goslings  following  her  and  the  gander  bringing  up  the  rear  to  be  sure 
there  were  no  stragglers;  if  a gosling  strayed  away  or  fell  behind,  the  male 
went  after  it,  pushing  it  back  into  the  family  circle.  When  entering  the 
coop  at  night  he  pushed  the  little  ones  in  gently  with  his  bill;  when  the 
goslings  took  their  first  swim  both  parents  gently  pushed  them  into  the 
water,  “rooted  them  in,”  as  the  farmer  said.  Any  attempt  to  take 
liberties  with  the  brood  was  met  with  bristling  anger  and  defiance  on  the 
part  of  the  gander;  the  mistress  of  the  farm  told  me  that  he  had  whipped 
her  black  and  blue  when  she  tried  to  interfere  with  the  goslings. 

The  gander  and  goose  always  show  suspicion  and  resentment  by  open- 
ing the  mouth  wide,  making  a hissing  noise,  showing  the  whole  round 
tongue  in  mocking  defiance.  When  the  gander  attacks,  he  thrusts  his 
head  forward,  even  with  or  below  the  level  of  his  back,  and  seizes  his  victim 
firmly  with  his  hard,  toothed  bill  so  that  it  cannot  get  away,  and  then  with 
his  strong  wings  beats  the  life  out  of  it.  I remember  vividly  a whipping 


Bird  Study  139 

which  a gander  gave  me  when  I was  a child,  holding  me  fast  by  the  blouse 
while  he  laid  on  the  blows. 

Geese  feed  much  more  largely  upon  land  vegetation  than  do  ducks; 
a good  growth  of  clover  and  grass  make  excellent  pasture  for  them ; in  the 
water,  they  feed  upon  water  plants  but  do  not  eat  insects  and  animals  to 
any  extent. 

Undoubtedly  goose  language  is  varied  and  expresses  many  things. 
Geese  talk  to  each  other  and  call  from  afar;  they  shriek  in  warning  and  in 
general  make  such  a turmoil  that  people  do  not  enjoy  it.  The  goslings, 
even  when  almost  grown,  keep  up  a constant  “pee  wee,  pee  wee,”  which  is 
nerve-racking.  There  is  a good  opportunity  for  some  interesting  investi- 
gations in  studying1 9%t  just  what  the  different  notes  of  the  geese  mean. 

The  goose  is  very  particular  about  her  toilet;  she  cleans  her  breast 
and  back  and  benesrth  her  wings  with  her  bill;  and  she  cleans  her  bill 
with  her  foot;  she  also  cleans  the  top  of  her  head  with  her  foot  and  the 
under  side  of  her  wing  with  the  foot  of  that  side.  When  oiling  her 
feathers,  she  starts  the  oil  gland  flowing  with  her  beak,  then  rubs  her  head 
over  the  gland  until  it  is  well  oiled;  she  then  uses  her  head  as  a “dauber” 
to  apply  the  oil  to  the  feathers  of  her  back  and  breast.  When  thus  pol- 
ishing her  feathers,  she  twists  the  head  over  and 
over  and  back  and  forth  to  add  to  its  efficiency. 

WILD  GEESE 

THERE  is  a sound,  that,  to  the  weather-wise  farmer, 
means  cold  and  snow,  even  though  it  is  heard 
through  the  hazy  atmosphere  of  an  Indian  summer 
day ; and  that  is  the  honking  of  wild  geese  as  they 
pass  on  their  southward  journey.  And  there  is  not  a 
more  interesting  sight  anywhere  in  the  autumn 
landscape  than  the  wedge-shaped  flock  of  these  long-necked  birds  with 
their  leader  at  the  front  apex.  “The  wild  goose  trails  his  harrow,” 
sings  the  poet;  but  only  the  aged  can  remember  the  old-fashioned  harrow 
which  makes  this  simile  graphic.  The  honking  which  reveals  to  us  the 
passing  flock,  before  our  eyes  can  discern  the  birds  against  the  sky,  is 
the  call  of  the  wise  old  gander  who  is  the  leader,  to  those  following  him, 
and  their  return  salute.  He  knows  the  way  on  this  long  thousand-mile 
journey,  and  knows  it  by  the  topography  of  the  country.  If  ever  fog 
or  storm  hides  the  earth  from  his  view,  he  is  likely  to  become  confused, 
to  the  dismay  of  his  flock,  which  follows  him  to  the  earth  with  many 
lonely  and  distressful  cries. 

The  northern  migration  takes  place  in  April  and  May,  and  the  southern 
from  October  to  December.  The  journey  is  made  with  stops  for  rest  and 
refreshment  at  certain  selected  places,  usually  some  secluded  pond  or 
lake.  The  food  of  wild  geese  consists  of  water  plants,  seeds  and  com, 
and  some  of  the  smaller  animals  living  in  water.  Although  the  geese  come 
to  rest  on  the  water,  they  go  to  the  shore  to  feed.  In  California,  the 
wild  geese  are  dreaded  visitors  of  the  cornfields,  and  men  with  guns  are 
employed  regularly  to  keep  them  off. 

The  nests  are  made  of  sticks  lined  with  down,  usually  along  the  shores 
of  streams,  sometimes  on  tree  stumps  and  sometimes  in  deserted  nests  of 
the  osprey.  There  are  only  four  or  five  eggs  laid  and  both  parents  are

Although  there  are  several  species  of  wild  geese  on  the  Atlantic 
Coast,  the  one  called  by  this  name  is  usually  the  Canada  goose.  This 

bird  is  a superb  creature.

that  during  the  night  a wild 
gander,  injured  in  some 
way,  had  joined  his  flock. 
The  stranger  was  treated 
with  much  courtesy  by  its 
new  companions  as  well  as 
by  the  farmer’s  family  and 
soon  seemed  perfectly  at

mated  with  one  of  the 
domestic  geese.  In  the  late

season  approached,  the  gander  became  very  uneasy;  not  only 
was  he  uneasy  and  unhappy  always  but  he  insisted  that  his 
wife  share  his  misery  of  unrest.  He  spent  days  in  earnest  remon- 
strance with  her  and,  licting  himself  by  his  cropped  wings  to  the  top  of 
the  barnyard  fence,  he  insisted  that  she  keep  him  company  on  this,  for

the  two  valiantly  started  south  on  foot.  News  was  received  of  their  prog- 
ress for  some  distance  and  then  they  were  lost  to  us.  During  the  winter  our 
neighbor  visited  a friend  living  eighteen  miles  to  the  southward  and 
found  in  his  barnyard  the  errant  pair.  They  had  become  tired  of 
migrating  by  tramping  and  had  joined  the  farmer’s  flock;  but  we  were 
never  able  to  determine  the  length  of  time  required  for  this  journey. 

LESSON  XXXIII 

Geese 

Leading  thought — Geese  are  the  most  intelligent  of  the  domesticated 
birds,  and  they  have  many  interesting  habits. 

Method — This  lesson  should  not  be  given  unless  there  are  geese  where 
the  pupils  may  observe  them.  The  questions  should  be  given  a few  at  a 
time  and  answered  individually  by  the  pupils  after  the  observations  are 
made.  • 

Observations — 1 . What  is  the  chief  difference  between  the  appearance 
of  a goose  and  a duck?  How  does  the  beak  of  the  goose  differ  from  that 
of  the  duck  in  shape  and  in  texture?  Describe  the  nostrils  and  their 
situation. 

2.  What  is  the  difference  in  shape  between  the  neck  of  the  goose  and 
that  of  the  duck? 

3.  What  can  you  say  about  the  plumage  of  geese?  Howt  are  geese 
“picked?”  At  what  time  of  year?  From  what  parts  of  the  body  are  the 
the  feathers  plucked? 

4.  Are  the  wings  of  the  goose  large  compared  with  the  body?  How 
do  geese  exercise  their  wings  ? Describe  the  tail  of  the  goose  and  how  it 
is  used. 

5.  How  do  the  legs  and  feet  of  the  goose  differ  from  those  of  the  duck? 
Describe  the  goose’s  foot.  How  many  toes  are  webbed?  Where  is  the 
other  toe?  What  is  the  shape  of  the  track  made  by  the  goose’s  foot? 
Which  portions  of  the  legs  are  used  for  oars?  When  the  goose  is  swim- 
ming forward  where  are  her  feet?  When  turning  around  how  does  she 
use  them?  Does  the  goose  waddle  when  walking  or  running  as  a duck 
does?  Why?  Does  a goose  toe-in  when  walking?  Why? 

6.  Describe  the  shape  and  color  of  the  following  breeds  of  domestic 
geese : The  Toulouse,  the  Embden,  the  African,  and  Chinese. 

Habits  of  Geese 

1.  What  is  the  chief  food  of  geese?  What  do  they  find  in  the  water 
to  eat  ? How  does  their  food  differ  from  that  of  ducks  ? 

2.  How  do  geese  differ  from  hens  in  the  matter  of  mating  and  nesting? 
At  what  time  of  year  do  geese  mate?  Does  a pair  usually  remain  mated 
for  life  ? 

3.  Describe  the  nest  and  compare  the  eggs  with  those  of  hens. 
Describe  the  young  goslings  in  general  appearance.  With  what  are  they 
covered?  What  care  do  the  parents  give  to  their  goslings?  Describe 
how  the  parents  take  their  family  afield.  How  do  they  induce  their 
goslings  to  go  into  the  water  for  the  first  time?  How  do  they  protect 
them  from  enemies  ? 


142 


Handbook  of  Nature-Study 


4.  How  does  the  gander  or  goose  fight  ? What  are  the  chief  weapons  ? 
How  is  the  head  held  when  the  attack  is  made  ? 

5.  How  does  the  goose  clean  her  feathers,  wings  and  feet  ? How  does 
she  oil  her  feathers?  Where  does  she  get  the  oil  and  with  what  does  she 
apply  it  ? 

6.  How  much  of  goose  language  do  you  understand?  What  is  the 
note  of  alarm?  How  is  defiance  and  distrust  expressed?  How  does  a 
goose  look  when  hissing?  What  is  the  constant  note  of  the  gosling? 

7 . Give  such  instances  as  you  may  know  illustrating  the  intelligence 
of  geese,  their  loyalty  and  bravery. 

8.  Write  an  English  Theme  on  “The  Canada  Goose,  its  appearance, 
nesting  habits,  and  migrations.”

THE  TURKEY 
Teacher's  Story 

HAT  the  turkey  and  not  the  eagle  should  have  been 
chosen  for  our  national  bird,  was  the  conviction  of 
Benjamin  Franklin.  It  is  a native  of  our  country, 
it  is  beautiful  as  to  plumage,  and  like  the  American 
Indian,  it  has  never  yielded  entirely  to  the  in- 
fluences of  civilization.  Through  the  hundreds  of 
years  of  domestication  it  still  retains  many  of  its 
wild  habits.  In  fact,  it  has  many  qualities  in 
common  with  the  red  man.  Take  for  instance  its 
sun  dance,  which  any  one  can  witness  who  is 
willing  to  get  up  early  enough  in  the  morning  and  who  has  a flock  of 
turkeys  at  hand.  Miss  Ada  Georgia  made  a pilgrimage  to  witness  this 
dance  and  she  describes  it  thus:  “While  the  dawn  was  still  faint  and 

gray,  the  long  row  of  birds  on  the  ridge-pole  stood  up,  stretched  legs  and 
wings  and  flew  down  into  the  orchard  beside  the  barnyard  and  began  a 
curious,  high-stepping,  ‘flip-flop’  dance  on  the  frosty  grass.  It  consisted 
of  little,  awkward,  up-and-down  jumps,  varied  by  forward  springs  of 
about  a foot,  with  lifted  wings.  Both  hens  and  males  danced,  the  latter 
alternately  strutting  and  hopping  and  all  ‘singing,’  the  hens  calling 
‘Quit,  quit,’  the  males  accompanying  with  a high-keyed  rattle,  sounding 
like  a hard  wood  stick  drawn  rapidly  along  a picket  fence.  As  the  sun 
came  up  and  the  sky  brightened,  the  exhibition  ended  suddenly  when 
‘The  Captain,’  a great  thirty  pound  gobbler  and  leader  of  the  flock,  made 
a rush  at  one  of  his  younger  brethren  who  had  dared  to  be  spreading  a tail 
too  near  to  his  majest}^.”

Handbook  of  Nature-Study 


The  bronze  breed  resembles  most  closely  our  native  wild  turkey  and  is 
therefore  chosen  for  this  lesson.  The  colors  and  markings  of  the  plumage 
form  the  bronze  turkey’s  chief  beauty.  From  the  skin  of  the  neck,  reach- 
ing half  way  to  the  middle  of  the  back  is  a collar  of  glittering  bronze  with 
greenish  and  purple  iridescence,  each  feather  tipped  with  a narrow  jet 
band.  The  remainder  of  the  back  is  black  except  that  each  feather  is 
edged  with  bronze.  The  breast  is  like  the  collar  and  at  its  center  is  a 
tassel  of  black  bristles  called  the  beard  which  hangs  limply  downward 
when  the  birds  are  feeding;  but  when  the  gobbler  stiffens  his  muscles  to 
strut,  this  beard  is  thrust  proudly  forth.  Occasionally  the  hen  turkeys 
have  a beard.  The  long  quills,  or  primaries,  of  the  wings  are  barred 
across  with  bands  of  black  and  white;  the  secondaries  are  very  dark, 
luminous  brown,  with  narrower  bars  of  white.  Each  feather  of  the  fan- 
shaped tail  is  banded  with  black  and  brown  and  ends  with  a black  bar 
tipped  with  white;  the  tail  coverts  are  lighter  brown  but  also  have  the 
black  margin  edged  with  white.  The  colors  of  the  hen  are  like  those  of 
the  gobbler  except  that  the  bronze  brilliance  of  breast,  neck  and  wings  is 
dimmed  by  the  faint  line  of  white  which  tips  each  feather. 

The  heads  of  all  are  covered  with  a warty  wrinkled  skin,  bluish  white 
on  the  crown,  grayish  blue  about  the  eyes,  and  the  other  parts  red. 
Beneath  the  throat  is  a hanging  fold  called  the  wattle,  and  above  the  beak 
a fleshy  pointed  knob  called  the  caruncle,  which  on  the  gobbler  is  pro- 
longed so  that  it  hangs  over  and  below  the  beak.  When  the  bird  is  angry 
these  carunculated  parts  swell  and  grow  more  vivid  in  color,  seeming  to 
be  gorged  with  blood.  The  color  of  the  skin  about  the  head  is  more  exten- 
sive and  brilliant  in  the  gobblers  than  in  the  hens.  The  beak  is  slightly 
curved,  short,  stout,  and  sharp-pointed,  yellowish  at  the  tip  and  dark  at 
the  base. 

The  eyes  are  bright,  dark  hazel  with  a thin  red  line  of  iris.  Just  back 
of  the  eye  is  the  ear,  seemingly  a mere  hole,  and  yet  it  leads  to  a very 
efficient  ear,  upon  which  every  smallest  sound  impinges. 

The  legs  of  the  young  turkeys  are  nearly  black,  fading  to  a brownish 
gray  when  mature.  The  legs  and  feet  are  large  and  stout,  the  middle 
toe  of  the  three  front  ones  being  nearly  twice  the  length  of  the  one  on 
either  side ; the  hind  toe  is  the  shortest  of  the  four.  On  the  inner  side  of 
the  gobbler’s  legs,  about  one-third  the  bare  space  above  the  foot,  is  a 
wicked  looking  spur  which  is  a most  effective  weapon.  The  wings  are 
large  and  powerful ; the  turkey  flies  well  for  such  a large  bird  and  usually 
roosts  high,  choosing  trees  or  the  ridge-pole  of  the  bam  for  this  purpose. 

In  many  ways  the  turkeys  are  not  more  than  half  domesticated.  They 
insistently  prefer  to  spend  their  nights  out  of  doors  instead  of  under  a 
roof.  They  are  also  great  wanderers  and  thrive  best  when  allowed  to 
forage  in  the  fields  and  woods  for  a part  of  their  food. 

The  gobbler  is  the  most  vainglorious  bird  known  to  us ; when  he  struts 
to  show  his  flock  of  admiring  hens  how  beautiful  he  is,  he  lowers  his  wings 
and  spreads  the  stiff  primary  quills  until  their  tips  scrape  the  ground,  lift- 
ing meanwhile  into  a semi-circular  fan  his  beautiful  tail  feathers ; he  pro- 
trudes his  chest,  raises  the  iridescent  plumage  of  his  neck  like  a ruff  to 
make  a background  against  which  he  throws  back  his  red,  white  and  blue 
decorated  head.  He  moves  forward  with  slow  and  mincing  steps  and 
calls  attention  to  his  grandeur  by  a series  of  most  aggressive  “gobbles.” 
But  we  must  say  for  the  gobbler  that  although  he  is  vain  he  is  also  a brave 


Bird  Study 


145 


fighter.  When  beginning  a fight  he  advances  with  wings  lowered  and 
sidewise  as  if  guarding  his  body  with  the  spread  wing.  The  neck  and  the 
sharp  beak  are  outstretched  and  he  makes  the  attack  so  suddenly,  that  it 
is  impossible  to  see  whether  he  strikes  with  both  wing  and  beak  or  only 
with  the  latter,  as  with  fury  he  pounces  upon  his  adversary  apparently 
striving  to  rip  his  neck  open  with  his  spurs. 

Turkey  hens  usually  begin  to  lay  in  April  in  this  latitude  and  much 
earlier  in  more  southern  states.  At  nesting  time  each  turkey  hen  strays 
off  alone,  seeking  the  most  secluded  spot  she  can  find  to  lay  the  large,  oval, 
brown-speckled  eggs.  Silent  and  sly,  she  slips  away  to  the  place  daily,  by 
the  most  round-about  ways,  and  never  moving  in  the  direction  of  the  nest 
when  she  thinks  herself  observed.  Sometimes  the  sight  of  any  person 
near  her  nest  will  cause  her  to  desert  it.  The  writer  has  spent  many  hours 
when  a child,  sneaking  in  fence  comers  and  behind  stumps  and  tree 
trunks,  stalking  turkeys’  nests.  Incubation  takes  four  weeks.  The 
female  is  a most  persistent  sitter  and  care  should  be  taken  to  see  that  she 
gets  a good  supply  of  food  and  water  at  this  time.  Good  sound  com  or 
wheat  is  the  best  food  for  her  at  this  period.  When  sitting  she  is  very 
cross  and  will  fight  most  courageously  when  molested  on  her  nest. 

Turkey  nestlings  are  rather  large,  with  long,  bare  legs  and  scrawny 
thin  necks,  and  they  are  very  delicate  during  the  first  six  weeks  of  their 
lives.  Their  call  is  a plaintive  “peep,  weep,”  and  when  a little  turkey 
feels  lost  its  cry  is  expressive  of  great  fear  and  misery.  But  if  the  mother 
is  freely  ranging  she  does  not  seem  to  be  much  affected  by  the  needs  of 
her  brood ; she  will  fight  savagely  for  them  if  they  are  near  her,  but  if  they 
stray,  and  they  usually  do,  she  does  not  seem  to  miss  or  hunt  for  them, 
but  strides  serenely  on  her  way,  keeping  up  a constant  crooning  “kr-rit, 
kr-rit,”  to  encourage  them  to  follow.  As  a consequence,  the  chicks  are 
lost  or  get  draggled  and  chilled  by  struggling  through  wet  grass  and 
leaves,  that  are  no  obstacle  to  the  mother’s  strong  legs,  and  thus  many 
die.  If  the  mother  is  confined  in  a coop  it  should  be  so  large  and  roomy 
that  she  can  move  about  without  trampling  on  the  chicks,  and  it  should 
have  a dry  floor  since  dampness  is  fatal  to  the  little  ones. 

For  the  first  week  the  chicks  should  be  fed  five  times  a day,  and  for 
the  next  five  weeks  they  should  have  three  meals  a day.  They  should  be 
given  only  just  about  enough  to  fill  each  little  crop  and  none  left  over  to  be 
trodden  under  their  awkward  little  feet.  Their  quarters  should  be  kept 
clean  and  free  from  vermin. 

LESSON  XXXIV 

Turkeys 

Leading  thought — The  turkey  is  a native  of  America.  It  was  intro- 
duced into  Spain  from  Mexico  in  about  1.518,  and  since  then  has  been 
domesticated.  However,  there  are  still  in  some  parts  of  the  country 
flocks  of  wild  turkeys.  It  is  a beautiful  bird  and  has  interesting  habits. 

Method — If  the  pupils  could  visit  a flock  of  turkeys  the  lesson  would  be 
given  to  a better  advantage.  If  this  is  impossible,  ask  the  questions  a few 
at  a time  and  let  those  pupils  who  have  opportunities  for  observing  the 
turkeys  give  their  answers  before  the  class. 

Observations — 1.  Of  what  breed  are  the  turkeys  you  are  studying, 
Bronze,  Black,  Buff,  White  Holland  or  Narragansett? 


146 


Handbook  of  Nature-Study 


2.  What  is  the  general  shape  and  size  of  the  turkey?  Describe  its 
plumage,  noting  every  color  which  you  can  see  in  it  ? Does  the  plumage 
of  the  hen  turkey  differ  from  that  of  the  gobbler? 

3.  What  is  the  covering  of  the  head  of  the  turkey,  what  is  its  color 
and  how  far  does  it  extend  down  the  neck  of  the  bird?  Is  it  always  the 
same  color,  and  if  not,  what  causes  the  change?  Is  the  head  covering 
alike  in  shape  and  size  on  the  male  and  the  female?  What  is  the  part 
called  that  hangs  from  the  front  of  the  throat  below  the  beak?  From 
above  the  beak? 

4.  What  is  the  color  of  the  beak?  Is  it  short  or  long,  straight  or 
curved  ? Where  are  the  nostrils  situated  ? 

5.  What  is  the  color  of  the  turkey’s  eyes?  Do  you  think  it  is  a keen- 
sighted  bird  ? 

6.  Where  are  the  ears?  Do  they  show  as  plainly  as  a chicken’s  ears 
do  ? Are  turkeys  quick  of  hearing  ? 

7.  Do  turkeys  scratch  like  hens?  Are  they  good  runners ? Describe 
the  feet  and  legs  as  to  shape,  size  and  color.  Has  the  male  a spur  on  his 
legs,  and  if  so,  where  is  it  situated-?  For  what  is  it  used? 

8.  Can  turkeys  fly  well  ? Are  the  wings  small  or  comparatively  large 
and  strong  for  the  weight  of  the  body?  Do  turkeys  prefer  high  or  low 
places  for  perching  when  they  sleep  ? Is  it  well  to  house  and  confine  them 
in  small  buildings  and  parks  as  is  done  with  other  fowls  ? 

9.  Tell,  as  nearly  as  you  can  discover  by  close  observation,  how  the 
gobbler  sets  each  part  of  his  plumage  when  he  is  “showing  off”  or  strut- 
ting? What  do  you  think  is  the  bird’s  purpose  in  thus  exhibiting  his  fine 
feathers?  Does  the  “King  of  the  flock”  permit  any  such  action  by  other 
“gobblers”  in  his  company? 

10.  Are  turkeys  timid  and  cowardly  or  independent  and  brave,  ready 
to  meet  and  fight  anything  which  they  think  is  threatening  to  their  com- 
fort and  safety  ? 

1 1 . When  turkeys  fight,  what  parts  of  their  bodies  seem  to  be  used 
as  weapons?  Does  the  male  “gobble”  during  a fight,  or  only  as  a chal- 
lenge or  in  triumph  when  victorious?  Do  the  hen  turkeys  ever  fight,  or 
only  the  males  ? 

12.  How  early  in  the  spring  does  the  turkey  hen  begin  to  lay?  Does 
she  nest  about  the  poultry  yard  and  the  bams  or  is  she  likely  to  seek  some 
secret  and  distant  spot  where  she  may  hide  her  eggs?  Describe  the 
turkey’s  egg,  as  well  as  you  can,  as  to  color,  shape  and  size.  Can  one  tell 
it  by  the  taste  from  an  ordinary  hen’s  egg?  About  how  many  eggs  does 
the  turkey  hen  lay  in  her  nest  before  she  begins  to  “get  broody”  and  want 
to  sit  ? 

13.  How  many  days  of  incubation  are  required  to  hatch  the  turkey 
chick?  Is  it  as  downy  and  pretty  as  other  little  chicks?  How  often 
should  the  young  chicks  be  fed,  and  what  food  do  you  think  is  best  for 
them  ? Are  turkey  chicks  as  hardy  as  other  chicks  ? 

14.  Is  the  turkey  hen  generally  a good  mother?  Is  she  cross  or 
gentle  when  sitting  and  when  brooding  her  young?  Is  it  possible  to  keep 
the  mother  turkey  as  closely  confined  with  her  brood  as  it  is  with  the 
mother  hen?  What  supplies  should  be  given  to  her  in  the  way  of  food, 
grits,  dust-baths,  etc.?

Bird  Study 
LESSON  XXXV 

The  Study  of  Birds’  Nests  in  Winter 

There  are  very  good  reasons  for  not  studying  birds’  nests  in  summer, 
since  too  much  familiarity  on  the  part  of  eager  children  is  something  the 
birds  do  not  understand  and  are  likely,  in  consequence,  to  abandon  both 
nest  and  locality.  But  after  the  birds  have  gone  to  sunnier  climes  and 
the  empty  nests  are  the  only  mementos  we  have  of  them,  then  we  may 
study  these  habitations  carefully  and  learn  how  to  properly  appreciate 
the  small  architects  which  made  them.  I think  that  every  one  of  us  who 
carefully  examines  the  way  that  a nest  is  made  must  have  a feeling  of 
respect  for  its  clever  little  builder. 

I know  of  certain  schools  where  the  children  make  large  collections  of 
these  winter  nests,  properly  labelling  each,  and  thus  gaining  a new 
interest  in  the  bird  life  of  their  locality.  A nest  when  collected  should  be 
labelled  in  the  following  manner? 

Name  of  the  bird  which  built  the  nest. 

Where  the  nest  was  found. 

If  in  a tree,  what  kind? 

How  high  from  the  ground? 

Bird  Homes,  by  A.  R.  Dugmore  is  a book  which  affords  practical 
help  in  determining  the  species  of  birds  which  made  the  nests. 

After  a collection  of  nests  has  been  made  let  the  pupils  study  them 
according  to  the  following  outline: 

1.  Where  was  the  nest  found? 

a.  If  on  the  ground,  describe  the  locality. 

b.  If  on  a plant,  tree  or  shrub,  tell  the  species,  if  possible. 

c.  If  on  a tree,  tell  where  it  was  on  a branch,  in  a fork,  or  hanging 
by  the  end  of  the  twigs. 

d.  How  high  from  the  ground,  and  what  was  the  locality? 

e.  If  on  or  in  a building,  how  situated? 

2 . Did  the  nest  have  any  arrangement  to  protect  it  from  rain  ? 

3 . Give  the  size  of  the  nest,  the  diameter  of  the  inside  and  the  outside ; 
also  the  depth  of  the  inside. 

4.  What  is  the  form  of  the  nest?  Are  its  sides  flaring  or  straight? 
Is  the  nest  shaped  like  a cup,  basket  or  pocket? 

5.  What  materials  compose  the  outside  of  the  nest  and  how  are  they 
arranged  ? 

6.  Of  what  materials  is  the  lining  made,  and  how  are  they  arranged? 
If  hair  or  feathers  are  used,  on  what  creature  did  they  grow? 

7.  How  are  the  materials  of  the  nest  held  together,  that  is,  are  they 
woven,  plastered,  or  held  in  place  by  environment? 

8.  Had  the  nest  anything  peculiar  about  it  either  in  situation,  con- 
struction or  material  that  would  tend  to  render  it  invisible  to  the  casual 
glance?

Fish  Study 
II.  FISH  STUDY 

“It  remains  yet  unresolved  whether  the  happiness  of  a man  in  this  world  doth  consist 
more  in  contemplation  or  action.  Concerning  which  two  opinions  I shall  forebear  to 
add  a third  by  declaring  my  own,  and  rest  myself  contented  in  telling  you  that  both  of 
these  meet  together,  and  do  most  properly  belong  to  the  most  honest,  ingenious,  quiet  and 
harmless  art  of  angling.  And  first  I tell  you  what  some  have  observed,  and  I have 
found  to  be  a real  truth,  that  the  very  sitting  by  the  riverside  is  not  only  the  quietest  and 
the  fittest  place  for  contemplation,  but  will  invite  an  angler  to  it .” — Isaak  Walton. 

M human,  old  Isaak  Walton  discovered  that  nature- 

study,  fishing,  and  philosophy  were  akin  and  as  inevitably 
related  as  the  three  angles  of  a triangle.  And  yet  it  is 
W / surprising  how  little  the  fish  have  been  used  as  subjects 

■/  W for  nature  lessons.  Every  brook  and  pond  is  a treasure 

to  the  teacher  who  will  find  what  there  is  in  it  and  who 
knows  what  may  be  gotten  out  of  it. 

Luckily  there  are  some  very  good  books  on  fishes  which  will  assist 
materially  in  making  the  fish  lessons  interesting:  Fishes,  by  David  Starr 

Jordan,  is  a magnificent  popular  work  in  two  volumes;  American  Food 
and  Game  Fishes,  by  Jordan  and  Evermann,  is  one  of  the  volumes  of  the 
valuably  Nature  Library.  While  for  supplementary  reading  the  follow- 
ing will  prove  instructive  and  entertaining:  The  Story  of  the  Fishes, 

Baskett;  Fish  Stories,  by  Holder  and  Jordan;  “The  Story  of  a Salmon,” 
in  Science  Sketches,  by  Jordan;  Neighbors  with  Wings  and  Fins,  Johon- 
not;  Half  Hours  with  Fishes,  Reptiles  and  Birds,  Holder. 

Almost  any  of  the  fishes  found  in  brook  or  pond  may  be  kept  in  an 
aquarium  for  a few  days  of  observation  in  the  schoolroom.  A water  pail 
or  bucket  does  very  well  if  there  is  no  glass  aquarium.  The  water  should 
be  changed  every  day  and  at  least  once  a day  it  should  be  aerated  by 
dipping  it  up  and  pouring  it  back  from  some  distance  above.  The  prac- 
tice should  be  established,  once  for  all,  of  putting  these  finny  prisoners 
back  into  the  brook  after  they  have  been  studied. 

THE  GOLDFISH 

Teacher's  Story 

NCE  upon  a time,  if  stories  are  true,  there  lived 
a king  called  Midas,  whose  touch  turned 
everything  to  gold.  Whenever  I see  gold- 
fish, I wonder  if,  perhaps,  King  Midas 
were  not  a Chinese  and  if  he  perchance 
did  not  handle  some  of  the  little  fish  in 
Orient  streams.  But  common  man  has 
learned  a magic  as  wonderful  as  that  of  King 
Midas,  although  it  does  not  act  so  im- 
mediately, for  it  is  through  his  agency  in 
selecting  and  breeding  that  we  have  gained  these  exquisite  fish  for  our 
aquaria.  In  the  streams  of  China  the  goldfish,  which  were  the  ancestors 
of  these  effulgent  creatures,  wore  safe  green  colors  like  the  shiners  in 
our  brooks;  and  if  any  goldfish  escape  from  our  fountains  and  run  wild, 
their  progeny  return  to  their  native  olive-green  color.  There  are  many

such  dull-colored  goldfish  in  the  Delaware  and  Potomac  and  other  east- 
ern rivers.  It  is  almost  inconceivable  that  one  of  the  brilliant  colored 
fishes,  if  it  chanced  to  escape  into  our  ponds,  should  escape  the  fate  of 
being  eaten  by  some  larger  fish  attracted  by  such  glittering  bait. 

The  goldfish,  as  we  see  it  in  the  aquarium,  is  brilliant  orange  above  and 
pale  lemon-yellow  below;  there  are  many  specimens  that  are  adorned 
with  black  patches.  And  as  if  this  fish  were  bound  to  imitate  the  precious 
metals,  there  are  individuals  which  are  silver  instead  of  gold:  they  are 
oxydized  silver  above  and  polished  silver  below.  The  goldfish  are  closely 
related  to  the  carp  and  can  live  in  waters  that  are  stale.  However,  the 
water  in  the  aquarium  should  be  changed  at  least  twice  a week  to  keep  it 
clear.  Goldfish  should  not  be  fed  too  lavishly.  An  inch  square  of  one  of 
the  sheets  of  prepared  fish  food,  we  have  found  a fair  daily  ration  for  five 
medium  sized  fish;  these  fish  are  more  likely  to  die  from  overfeeding  than 
from  starving.  Goldfish  are  naturally  long-lived;  Miss  Ada  Georgia  has 
kept  them  until  seven  years  old  in  a school  aquarium;  and  there  is  on 
record  one  goldfish  that  lived  nine  years. 

Too  often  the  wonderful  common  things  are  never  noticed  because  of 
their  commonness;  and  there  is  no  better  instance  of  this  than  the  form 
and  movements  of  a fish.  It  is  an  animal  in  many  ways  similar  to  ani- 
mals that  live  on  land;  but  its  form  and  structure  are  such  that  it  is 
perfectly  adapted  to  live  in  water  all  its  life;  there  are  none  of  the  true 
fishes  which  live  portions  of  their  lives  on  land  as  do  the  frogs.  The  first 
peculiarity  of  the  fish  is  its  shape.  Looked  at  from  above,  the  broader 
part  of  the  body  is  near  the  front  end  which  is  rounded  or  pointed  so  as  to 
cut  the  water  readily.  The  long,  narrow,  hind  portion  of  the  body  with 
the  tail  acts  as  a propeller.  Seen  from  the  side,  the  body  is  a smooth, 
graceful  oval  and  this  form  is  especially  adapted  to  move  through  the 
water  swiftly,  as  can  be  demonstrated  to  the  pupil  by  cutting  a model  of 
the  fish  from  wood  and  trying  to  move  it  through  the  water  sidewise. 

Normally,  the  fish  has  seven  fins,  one  along  the  back  called  the  dorsal, 
one  at  the  end  of  the  tail  called  the  tail  or  caudal  fin,  one  beneath  the  rear 
end  of  the  body  called  the  anal,  a pair  on  the  lower  side  of  the  body  called 
the  ventrals,  and  a pair  just  back  of  the  gill  openings  called  the  pectorals. 
All  these  fins  play  their  own  parts  in  the  movements  of  the  fish.  The  dor- 


This  figure  should  be  copied  on  the  blackboard  for  reference.

sal  fin  is  usually  higher  in  front  than  behind  and  can  be  lifted  or  shut  down 
like  a fan.  This  fin  when  it  is  lifted  gives  the  fish  greater  height  and  it 
can  be  twisted  to  one  side  or  the  other  and  thus  be  made  a factor  in 
steering.  The  anal  fin  on  the  lower  side  acts  in  a similar  manner.  The 
tail  fin  is  the  propeller  and  sends  the  body  forward  by  pressing  backward 
on  the  water,  first  on  one  side  and  then  on  the  other,  being  used  like  a 
scull.  The  tail  fin  varies  in  shape  very  much  in  different  species.  In  the 
goldfish  it  is  fanlike,  with  a deeply  notched  hind  edge,  but  in  some  it  is 
rounded  or  square. 

The  paired  fins  correspond  anatomically  to  our  arms  and  legs,  the 
pectorals  representing  the  arms,  the  ventrals  the  legs.  Fins  are  made  up 
of  rays,  as  the  bony  rods  are  called  which  support  the  membrane;  these 
rays  are  of  two  kinds,  those  which  are  soft,  flexible,  many  jointed  and 
usually  branched  at  the  tip;  and  those  which  are  bony,  not  jointed  and 
which  are  usually  stiff  spines.  When  the  spines  are  present  in  a fin  they 
precede  the  soft  rays. 

Fishes’  eyes  have  no  eyelid  but  the  eyeball  is  movable,  and  this  often 
gives  the  impression  that  the  fish  winks.  Fishes  are  necessarily  near- 
sighted since  the  lens  of  the  eye  has  to  be  spherical  in  order  to  see  in  the 
water.  The  sense  of  smell  is  located  in  a little  sac  to  which  the  nostril 
leads;  the  nostrils  are  small  and  often  partitioned  and  may  be  seen  on 
either  side  of  the  snout.  The  nostrils  have  no  connection  whatever  with 
breathing,  in  the  fish. 

The  tongue  of  the  fish  is  very  bony  or  bristly  and  immovable.  There 
is  very  little  sense  of  taste  developed  in  it.  The  shape,  number  and 
position  of  the  teeth  vary  according  to  the  food  habits  of  the  fish.  The 
commonest  type  of  teeth  are  fine,  sharp  and  short  and  are  arranged  in 
pads,  as  seen  in  the  bullhead.  Some  fish  have  blunt  teeth  suitable  for 
crushing  shells.  Herbivorous  fishes  have  sharp  teeth  with  serrated  edges, 
while  those  living  upon  crabs  and  snails  have  incisor-like  teeth.  In  some 
specimens  we  find  several  types  of  teeth,  in  others  the  teeth  may  be 
entirely  absent.  The  teeth  are  borne  not  only  on  the  jaws  but  also  in  the 
roof  of  the  mouth,  on  the  tongue  and  in  the  throat. 

The  ear  of  the  fish  has  neither  outside  form  nor  opening  and  is  very 
imperfect  in  comparison  with  that  of  man.  Extending  along  the  sides  of 
the  body  from  head  to  tail  is  a line  of  modified  scales  containing  small 
tubes  connecting  with  nerves;  this  is  called  the  lateral  line  and  it  is 
believed  that  it  is  in  some  way  connected  with  the  fish’s  senses,  perhaps 
with  the  sense  of  hearing. 

Since  fishes  must  push  through  water,  which  is  more  difficult  than 
moving  through  air,  they  need  to  have  the  body  well  protected.  This 
protection  is,  in  most  fishes,  in  the  form  of  an  armor  of  scales  which  are 
smooth  and  allow  the  body  to  pass  through  the  water  with  little  friction. 
These  scales  overlap  like  shingles  in  a roof  and  are  all  directed  backward. 
The  study  of  the  fish  scale  shows  that  it  grows  in  layers. 

In  order  to  understand  how  the  fish  breathes  we  must  examine  its  gills. 
In  front,  just  above  the  entrance  to  the  gullet  are  several  bony  ridges 
which  bear  two  rows  of  pinkish  fringes ; these  are  the  gill  arches  and  the 
fringes  are  the  gills.  The  gills  are  filled  with  tiny  bloodvessels,  and  as  the 
water  passes  over  them,  the  impurities  of  the  blood  pass  out  through  the 
thin  skin  of  the  gills  and  the  life-giving  oxygen  passes  in.  Since  fish 
cannot  make  use  of  air  unless  it  is  dissolved  in  water,  it  is  very  important 


*5* 


Handbook  of  Nature-Study 


that  the  water  in  the  aquarium  jar  should  often  be  replenished.  The  gill 
arches  also  bear  a series  of  bony  processes  called  gill-rakers.  Their 
function  is  to  prevent  the  escape  of  food  through  the  gills  while  it  is  being 
swallowed,  and  they  vary  in  size  according  to  the  food  habits  of  the  fish. 
We  note  that  the  fish  in  the  aquarium  constantly  opens  and  closes  the 
mouth;  this  action  draws  the  water  into  the  throat  and  forces  it  out  over 
the  gills  and  through  the  gill  openings;  this  then,  is  the  act  of  breathing. 

LESSON  XXXVI 
A Study  of  the  Fish 

Leading  thought — A fish  lives  in  the  water  where  it  must  breathe,  move 
and  find  its  food.  The  water  world  is  quite  different  from  the  air  world 
and  the  fish  have  developed  forms,  senses  and  habits  which  fit  them  for 
life  in  the  water. 

Method — The  goldfish  is  used  as  a subject  for  this  lesson  because  it  is 
so  conveniently  kept  where  the  children  may  see  it.  However,  a shiner 
or  minnow  would  do  as  well. 

Before  the  pupils  begin  the  study,  place  the  diagram  shown  on  p.  150 
on  the  blackboard,  with  all  the  parts  labelled;  thus  the  pupils  will  be  able 
to  learn  the  parts  of  the  fish  by  consulting  it,  and  not  be  compelled  to 
commit  them  to  memory  arbitrarily.  It  would  be  well  to  associate  the 
goldfish  with  a geography  lesson  on  China. 

Observations — 1.  Where  do  fishes  live?  Do  any  fishes  ever  live  any 
part  of  their  lives  on  land  like  the  frogs?  Could  a salt-water  fish  live  in 
fresh  water,  or  vice  versa  ? 

2.  What  is  the  shape  of  a fish  when  seen  from  above?  Where  is  the 
widest  part?  What  is  its  shape  seen  from  the  side ? Think  if  you  can  in 
how  many  ways  the  shape  of  the  fish  is  adapted  for  moving  swiftly  through 
the  water. 

3.  How  many  fins  has  the  fish?  Make  a sketch  of  the  goldfish  with 
all  its  fins  and  name  them  from  the  diagram  on  the  blackboard. 

4.  How  many  fins  are  there  in  all?  Four  of  these  fins  are  in  pairs; 
where  are  they  situated?  What  are  they  called?  Which  pair  corres- 
ponds to  our  arms?  Which  to  our  legs? 

5.  Describe  the  pectoral  fins.  How  are  they  used?  Are  they  kept 
constantly  moving?  Do  they  move  together  or  alternately?  How  are 
they  used  when  the  fish  swims  backwards? 

6.  How  are  the  ventral  fins  used?  How  do  they  assist  the  fish 
when  swimming? 

7.  Sketch  a dorsal  fin.  How  many  spines  has  it?  How  many  soft 
rays  are  there  in  it?  What  is  the  difference  in  structure  between  the  stiff 
spines  in  the  front  of  the  dorsal  fin  and  the  rays  in  the  hind  portion?  Of 
what  use  to  the  fish  are  these  two  different  kinds  of  fin  supports  ? 

8.  Sketch  the  anal  fin.  Has  it  any  spines  in  front?  How  many 
rays  has  it?  How  is  this  fin  used  when  the  fish  is  swimming? 

9.  With  what  fin  does  the  fish  push  itself  through  the  water? 
Make  a sketch  of  the  tail.  Note  if  it  is  square,  rounded,  or  notched  at  the 
end.  Are  the  rays  of  the  tail  fin  spiny  or  soft  in  character? 

10.  Watch  the  goldfish  swim  and  describe  the  action  of  all  the  fins 
while  it  is  in  motion.  In  what  position  are  the  fins  when  the  fish  is  at 
rest?

1 1 . What  is  the  nature  of  the  covering  of  the  fish  ? Are  the  scales 
large  or  small?  In  which  direction  do  they  seem  to  overlap?  Of  what 
use  to  the  fish  is  this  scaly  covering? 

12.  Can  you  see  a line  which  extends  from  the  upper  part  of  the  gill 
opening,  along  the  side  to  the  tail?  This  is  called  the  lateral  line.  Do 
you  think  it  is  of  any  use  to  the  fish? 

13.  Note  carefully  the  eyes  of  the  fish.  Describe  the  pupil  and  the 
iris.  Are  the  eyes  placed  so  that  the  fish  can  see  in  all  directions?  Can 
they  be  moved  so  as  to  see  better  in  any  direction?  Does  the  fish  wink? 
Has  it  any  eyelids?  Do  you  know  why  fish  are  near-sighted? 

14.  Can  you  see  the  nostrils?  Is  there  a little  wartlike  projection 
connected  with  the  nostril?  Do  you  think  fishes  breathe  through  their 
nostrils? 

15.  Describe  the  mouth  of  the  fish.  Does  it  open  upward,  down- 
ward, or  directly  in  front?  What  sort  of  teeth  have  fish?  How  does  the 
fish  catch  its  prey?  Does  the  lower  or  upper  jaw  move  in  the  process  of 
eating? 

16.  Is  the  mouth  kept  always  in  motion?  Do  you  think  the  fish  is 
swallowing  water  all  the  time  ? Do  you  know  why  it  does  this  ? Can  you 
see  a wide  opening  along  the  sides  of  the  head  behind  the  gill  cover? 
Does  the  gill  cover  move  with  the  movement  of  the  mouth?  How  does  a 
fish  breathe  ? 

17.  What  are  the  colors  of  the  goldfish  above  and  below?  What 
would  happen  to  our  beautiful  goldfish  if  they  were  put  in  a brook  with 
other  fish?  Why  could  they  not  hide?  Do  you  know  what  happens  to 
the  colors  of  the  goldfish  when  they  run  wild  in  our  streams  and  ponds? 

18.  Can  you  find  in  books  or  cyclopedias  where  the  goldfish  came 
from?  Are  they  gold  and  silver  in  color  in  the  streams  where  they  are 
native?  Do  you  think  that  they  had  originally  the  long,  slender,  swallow 
tails  which  we  see  sometimes  in  goldfish?  How  have  the  beautiful  colors 
and  graceful  forms  of  the  gold  and  silver  fishes  been  developed?

Bullhead  at  bottom  of  a pond.

THE  BULLHEAD 


Teacher's  Story 

The  bull-head  does  usually  dwell  and  hide  himself  in  holes  or  amongst  stones  in 
clear  water;  and  in  very  hot  days  will  lie  a long  time  very  still  and  sun  himself  and  will 
be  easy  to  be  seen  on  any  flat  stone  or  gravel;  at  which  time  he  will  suffer  an  angler  to 
put  a hook  baited  with  a small  worm  very  near  into  his  mouth;  and  he  never  refuses  to 
bite , no'hindeed,  to  be  caught  with  the  worst  of  anglers.” — Isaak  Walton. 

HEN  one  looks  a bullhead  in  the  face  one  is 
glad  that  it  is  not  a real  bull  for  its  barbels 
give  it  an  appearance  quite  fit  for  the 
making  of  a nightmare;  and  yet  from 
the  standpoint  of  the  bullhead,  how 
truly  beautiful  those  fleshy  feelers  are! 
For  without  them  how  could  it  feel  its 
way  about  searching  for  food  in  the 
mud  where  it  lives?  Two  of  these  barbels  stand  straight  up;  the 
two  largest  ones  stand  out  on  each  side  of  the  mouth,  and  two  pairs  of 
short  ones  adorn  the  lower  lip,  the  smallest  pair  at  the  middle. 

As  the  fish  moves  about,  it  is  easy  to  see  that  the  large  barbels  at  the 
side  of  the  mouth  are  of  the  greatest  use;  it  keeps  them  in  a constantly 
advancing  movement,  feeling  of  everything  it  meets.  The  upper  ones 
stand  straight  up,  keeping  watch  for  whatever  news  there  may  be  from 
above;  the  two  lower  ones  spread  apart  and  follow  rather  than  precede 
the  fish,  seeming  >.o  test  what  lies  below.  The  upper  and  lower  pairs  seem 
to  test  things  as  they  are,  while  the  large  side  pair  deal  with  what  is  going 
to  be.  The  broad  mouth  seems  to  be  formed  for  taking  in  all  things  eatable, 
for  the  bullhead  lives  on  almost  anything  alive  or  dead  that  it  discovers  as  it 
noses  about  in  the  mud.  Nevertheless,  it  has  its  notions  about  its  food 
for  I have  repeatedly  seen  one  draw  material  into  its  mouth  through  its 
breathing  motion  and  then  spew  it  out  with  a vehemence  one  would  hardly 
expect  from  such  a phlegmatic  fish.

Although  it  has  feelers  which  are  very  efficient,  it  also  has  perfectly 
good  eyes  which  it  uses  to  excellent  purpose;  note  how  promptly  it  moves 
to  the  other  side  of  the  aquarium  when  we  are  trying  to  study  it.  The  eyes 
are  not  large ; the  pupils  are  black  and  oval  and  are  rimmed  with  a narrow 
band  of  shiny  pale  yellow.  The  eyes  are  prominent  so  that  when  moved 
backward  and  forward  they  gain  a view  of  the  enemy  in  the  rear  or  at  the 
front  while  the  head  is  motionless.  It  seems  strange  to  see  such  a pair  of 
pale  yellow,  almost  white  eyes  in  such  a dark  body. 

The  general  shape  of  the  front  part  of  the  body  is  flat,  in  fact,  it  is 
decidedly  polywogy;  this  shape  is  especially  fitted  for  groping  about 
muddy  bottoms.  The  flat  effect  of  the  body  is  emphasized  by  the  gill 
covers  opening  below  rather  than  at  the  sides,  every  pulsation  widening 
the  broad  neck.  The  pectoral  fins  also  open  out  on  the  same  plane  as  the 
body  although  they  can  be  turned  at  an  angle  if  necessary;  they  are  thick 
and  fleshy  and  the  sharp  tips  of  their  spines  offer  punishment  to  whom- 
soever touches  them.  The  dorsal  fin  is  far  forward  and  not  large;  it  is 
usually  raised  at  a threatening  angle. 

There  is  a little  fleshy  dorsal  fin  near  the  tail  which  stands  in  line  with 
the  body  and  one  wonders  what  is  its  special  use.  The  ventral  fins  are 
small.  The  anal  fin  is  far  back  and  rather  strong,  and  this  with  the  long, 
strong  tail  gives  the  fish  good  motor  power  and  it  can  swim  very  rapidly 
if  occasion  requires. 

The  bullhead  is  mud-colored  and  has  no  scales;  and  since  it  lives  in  the 
mud,  it  does  not  need  scales  to  protect  it;  but  because  of  its  scaleless  con- 
dition it  is  a constant  victim  of  the  lampreys,  and  it  would  do  well, 
:ndeed,  if  it  could  develop  an  armor  of  scales  against  this  parasite.  The

skin  is  very  thick  and  leathery  so  that  it  is  always  removed  before  the  fish 
is  cooked.  The  bullhead  is  the  earliest  fish  of  the  spring.  This  is 
probably  because  it  burrows  deep  into  the  mud  in  the  fall  and  remains 
there  all  winter ; when  the  spring  freshets  come,  it  emerges  and  is  hungry 
for  fresh  meat. 

The  family  life  of  the  bullheads  and  other  catfishes  seems  to  be  quite 
ideal.  Dr.  Theodore  Gill  tells  us  that  bullheads  make  their  nests  by 
removing  stones  and  gravel  from  a more  or  less  irregularly  circular  area 
in  shallow  water,  and  on  sandy  or  gravelly  ground.  The  nest  is  somewhat 
excavated,  both  parents  removing  the  pebbles  by  sucking  them  into  the 
mouth  and  carrying  them  off  for  some  distance.  After  the  eggs  are  laid, 
the  male  watches  over  and  guards  the  nest  and  seems  to  have  great  family 
responsibilities.  He  is  the  more  active  of  the  two  in  stirring  and  mixing 
the  young  fry  after  they  are  hatched.  Smith  and  Harron  describe  the 
process  thus:  “With  their  chins  on  the  bottom,  the  old  fish  brush  the 

comers  where  the  fry  were  banked,  and  with  the  barbels  all  directed  for- 
ward, and  flexed  where  they  touch  the  bottom,  thoroughly  agitate  the 
mass  of  fry,  bringing  the  deepest  individuals  to  the  surface.  This  act  is 
usually  repeated  several  times  in  quick  succession.” 

“The  nests  are  usually  made  beneath  logs  or  other  protecting  objects 
and  in  shallow  water.  The  paternal  care  is  continued  for  many  days 
after  the  birth  of  the  young.  At  first  these  may  be  crowded  together  in 
a dense  mass,  but  as  time  passes  they  disperse  more  and  more  and  spread 
around  the  father.  Frequently,  especially  when  the  old  one  is  feeding, 
some — one  or  more — of  the  young  are  taken  into  the  mouth,  but  they  are 
instinctively  separated  from  the  food  and  spit  out.  At  last  the  young 
swarm  venture  farther  from  their  birthplace,  or  perhaps  they  are  led 
away  by  their  parents.” 


LESSON  XXXVII 
The  Bullhead,  or  Horned  Pout 

Leading  thought — The  bullhead  lives  in  mud  bottoms  of  streams  and 
ponds  and  is  particularly  adapted  for  life  in  such  locations. 

Method — A small  bullhead  may  be  placed  in  a small  aquarium  jar. 
At  first  let  the  water  be  clear  and  add  a little  pond  weed  so  as  to  observe 
the  natural  tendency  of  the  fish  to  hide.  Later  add  mud  and  gravel  to  the 
aquarium  and  note  the  behavior  of  the  fish. 

Observations — 1.  What  at  the  first  glance  distinguishes  the  bullhead 
from  other  fish?  Describe  these  strange  “’whiskers”  growing  about  the 
mouth;  how  many  are  there  and  where  are  they  situated?  Which  are 
the  longest  pair?  Can  the  fish  move  them  in  any  direction  at  will? 

2.  Where  do  we  find  bullheads?  On  what  do  they  feed?  Would 
their  eyes  help  them  to  find  their  food  in  the  mud?  How  do  they  find  it? 

3.  Explain,  if  you  can,  why  the  bullhead  has  barbels,  or  feelers, 
while  the  trout  and  bass  have  none. 

4.  What  is  the  shape  of  the  bullhead’s  mouth? 

5.  What  is  the  general  shape  of  the  body?  What  is  its  color?  Has 
it  any  scales  ? 

6.  Why  should  the  bullhead  be  so  flat  horizontally  while  the  sun- 
fish  is  so  flat  in  the  opposite  direction? 


Fish  Study 


i57 


7.  Describe  the  bullhead’s  eyes.  Are  they  large?  What  is  their 
color?  Where  are  they  placed? 

8.  Describe  the  dorsal  fin,  giving  its  comparative  size  and  position. 
Do  you  see  another  dorsal  fin?  Where  is  this  peculiar  fin  and  how  does  it 
differ  from  the  others? 

9.  Describe  the  tail  fin.  Does  it  seem  long  and  strong?  Is  the 
bullhead  a good  swimmer? 

10.  Is  the  anal  fin  large  or  small  as  compared  with  that  of  the  gold- 
fish? 

1 1 . How  do  the  pectoral  fins  move  as  compared  with  those  of  the 

sunfish  ? Why  is  the  position  of  the  pectoral  and  dorsal  fins  of  benefit  to 

this  fish? 

12.  How  does  the  bullhead  inflict  wounds  when  it  is  handled?  Tell 
how  these  spines  protect  it  from  its  natural  enemies. 

13.  When  is  the  best  season  for  fishing  for  bullheads?  Does  the 
place  where  they  are  found  affect  the  flavor  of  their  flesh?  Why? 

14.  What  is  the  spawning  season?  Do  you  know  about  the  nests 
the  bullheads  build  and  the  care  they  give  their  young? 

15.  Write  an  essay  on  the  nest-making  habits  of  the  bullheads  and 
the  care  given  the  young  by  the  parents. 


“ And  what  fish  will  the  natural  hoy  naturally  take?  In  America,  there  is  but  one 
fish  which  enters  fully  into  the  spirit  of  the  occasion.  It  is  a fish  of  many  species 
according  to  the  part  of  the  country,  and  of  as  many  sizes  as  there  are  sizes  of  boys. 
This  fish  is  the  horned  pout,  and  all  the  rest  of  the  species  of  Ameiurus.  Horned  pout 
is  its  Boston  name.  Bullhead  is  good  enough  for  New  York;  and  for  the  rest  of  the 
country,  big  and  little,  all  the  fishes  of  this  tribe  are  called  catfish.  A catfish  is  a jolly 
blundering  sort  of  a fish,  a regular  Falstaff  of  the  ponds.  It  has  a fat  jowl,  and  a fat 
belly,  which  it  is  always  trying  to  fill.  Smooth  and  sleek,  its  skin  is  almost  human  in  its 
delicacy.  It  wears  a long  mustache,  with  scattering  whiskers  of  other  sort.  Mean- 
while it  always  goes  armed  with  a sword,  three  swords,  and  these  it  has  always  on  hand, 
always  ready  for  a struggle  on  land  as  well  as  in  the  water.  The  small  boy  often  gets 
badly  stuck  on  these  poisoned  daggers,  but,  as  the  fish  knows  how  to  set  them  by  a mus- 
cular twist,  the  small  boy  learns  how , by  a like  untwist,  he  may  unset  and  leave  them 
harmless. 

The  catfish  lives  in  sluggish  waters.  It  loves  the  millpond  best  of  all,  and  it  has  no 
foolish  dread  of  hooks  when  it  goes  forth  to  bite.  Its  mouth  is  wide.  It  swallows  the 
hook,  and  very  soon  it  is  in  the  air,  its  white  throat  gasping  in  the  untried  element.  Soon 
it  joins  its  fellows  on  the  forked  stick,  and  even  then,  uncomfortable  as  it  may  find  its 
new  relations,  it  never  loses  sight  of  the  humor  of  the  occasion.  Its  large  head  and 
expansive  forehead  betoken  a large  mind.  It  is  the  only  fish  whose  brain  contains  a 
Sylvian  fissure,  a piling  up  of  tissue  consequent  on  the  abundance  of  gray  matter.  So 
it  understands  ana  makes  no  complaint.  After  it  has  dried  in  the  sun  for  an  hour,  pour 
a little  water  over  its  gills,  and  it  will  wag  its  tail , and  squeak  with  gratitude.  And  the 
best  of  all  is,  there  are  horned  pouts  enough  to  go  around.” 

“ The  female  horned  pout  lays  thousands  of  eggs,  and  when  these  hatch,  she  goes 
about  near  the  shore  with  her  school  of  little  fishes,  like  a hen  with  myriad  chicks.  She 
should  be  respected  and  let  alone,  for  on  her  success  in  rearing  this  breed  of  “ bullying 
little  ranger s’^  depends  the  sport  of  the  small  boy  of  the  future.”

Fishing  for  suckers.

THE  COMMON  SUCKER 

Teacher's  Story 

yE  who  loves  to  peer  down  into  the  depths  of  still  waters,  often 
sees  upon  the  sandy,  muddy  or  rocky  bottom  several 
? long,  wedge-shaped  sticks  lying  at  various  angles  one  to 
\ another.  But  if  he  thrust  down  a real  stick,  behold,  these 
[ inert,  water-logged  sticks  move  off  deftly!  And  then  he 
i knows  that  they  are  suckers.  He  may  drop  a hook  baited 
with  a worm  in  front  of  the  nose  of  one,  and  if  he  waits 
long  enough  before  he  pulls  up  he  may  catch  this  fish,  not  by  its  gills 
but  by  the  pit  of  its  stomach ; for  it  not  only  swallows']  the  hook  com- 
pletely but  tries  to  digest  it  along  with  the  worm.  Its  food  is  made  up 
of  soft-bodied  insects  and  other  small  water  creatures;  it  is  also  a mud 
eater  and  manages  to  make  a digestive  selection  from  the  organic 
material  of  silt.  For  this  latter  reason,  it  is  not  a desirable  food  fish 
although  its  flesh  varies  in  flavor  with  the  locality  where  it  is  found. 
The  suckers  taken  along  the  rocky  shores  of  Cayuga  Lake  are  fairly 
palatable,  while  those  taken  in  the  mud  of  the  Cayuga  Inlet  are  very  in- 
ferior in  flavor  and  often  uneatable. 

Seen  from  above,  the  sucker  is  wedge-shaped,  being  widest  at  the  eyes; 
seen  from  the  side  it  has  a flat  lower  surface  and  an  ungracefully  rounded 
contour  above  which  tapers  only  slightly  toward  the  tail.  The  profile  of  the 
face  gives  the  impression  of  a Roman  nose.  The  young  specimens  have 
an  irregular  scale-mosaic  pattern  of  olive-green  blotches  on  a paler  ground 
color,  while  the  old  ones  are  quite  brown  above  and  on  the  sides.  The 
suckers  differ  from  most  other  fishes  in  having  the  markings  of  the  back 
extend  down  the  sides  almost  to  the  belly.  This  is  a help  in  concealing 
the  fish,  since  its  sides  show  from  above  quite  as  distinctly  as  its  back 


Fish  Study

because  of  its  peculiar  form.  The  scales  are  rather  large  and  are  notice- 
ably larger  behind  than  in  the  region  of  the  head.  Like  other  fish  it  is 
white  below. 

The  dorsal  fin  is  placed  about  midway  the  length  of  the  fish  as  measured 
from  nose  to  tail.  It  is  not  large  and  appears  to  have  twelve  rays;  but 
there  is  a short  spine  in  front  and  a delicate  Soft  ray  behind  so  that  it 
really  has  fourteen.  The  tail  is  long  and  strong  and  deeply  notched: 
the  anal  fin  extends  back  to  where  the  tail  begins.  The  ventral  fins  are 
small  and  are  directly  opposite  the  hind  half  of  the  dorsal  fin.  The  pec- 
torals are  not  large  but  are  strong  and  are  placed  low  down.  The  sucker 
has  not  a lavish  equipment  of  fins  but  its  tail  is  strong  and  it  can  swim 
swiftly;  it  is  also  a tremendous  jumper;  it  will  jump  from  the  aquarium 
more  successfully  than  any  other  fish.  When  resting  on  the  bottom,  it  is 
supported  by  its  extended  pectoral  and  ventral  fins,  which  are  strong 
although  not  large. 

The  eyes  are  fairly  large  but  the  iris  is  not  shiny;  they  are  placed  so 
that  the  fish  can  easily  see  above  it  as  well  as  at  the  sides;  the  eyes 
move  so  as  to  look  up  or  down  and  are  very  well  adapted  to  serve  a fish 
that  lives  upon  the  bottom.  The  nostrils  are  divided,  the  partition  pro- 
jecting until  it  seems  a tubercle  on  the  face.  The  mouth  opens  below  and 
looks  like  the  puckered  opening  of  a bag.  The  lips  are  thick  but  are  very 
sensitive;  it  is  by  projecting  these  lips,  in  a way  that  reminds  one  of  a 
very  short  elephant’s  trunk,  that  it  is  enabled  to  reach  and  find  its  food 
in  the  mud  or  gravel;  so  although  the  sucker’s  mouth  is  not  a beautiful 
feature,  it  is  doubly  useful.  The  sucker  has  the  habit  of  remaining 
motionless  for  long  periods  of  time.  It  breathes  very  slowly  and  appears 
sluggish;  it  never  seizes  its  food  with  any  spirit  but  simply  slowly  en- 
gulfs it;  and  for  this  reason  it  is  considered  poor  game.  It  is  only  in  the 
spring  when  they  may  be  speared  through  the  .ice  that  there  is  any  fun  in 
catching  suckers;  it  is  at  this  season  of  the  year  that  they  move  to  shallow 
water  to  spawn;  those  in  the  lakes  move  to  the  rivers,  those  in  the  rivers 
to  the  creeks,  those  in  the  creeks  to  the  brooks.  Even  so  lowly  a creature 
as  the  sucker  seems  to  respond  to  influences  of  the  springtime,  for  at  that 
period  the  male  has  a faint  rosy  stripe  along  his  sides.  In  the  winter  these 
fish  burrow  in  the  mud  of  the  river  or  pond  bottoms;  they  may  be  frozen 
and  thawed  without  harming  them. 

There  are  many  species  of  suckers  and  they  vary  in  size  from  six 
inches  to  three  feet  in  length.  They  inhabit  all  sorts  of  waters,  but  they 
do  not  like  a strong  current  and  are,  therefore,  found  in  still  pools.  The 
common  sucker  ( Catostomus  commersoni),  which  is  the  subject  of  this 
lesson,  sometimes  attains  the  length  of  twenty-two  inches  and  the  weight 
of  five  pounds.  The  ones  under  observation  were  about  eight  inches 
long,  and  proved  to  be  the  acrobats  of  the  aquarium,  since  they  were 
likely  at  any  moment  to  jump  out;  several  times  I found  one  languishing 
on  the  floor.

LESSON  XXXVIII 
The  Common  Sucker 

Leading  thought — The  sucker  is  especially  adapted  by  shape  for  lying 
on  the  bottom  of  ponds  under  still  water  where  its  food  is  abundant. 

Method — If  still  water  pools  along  river  or  lakesides  are  accessible,  it  is 
far  more  interesting  to  study  a sucker  in  its  native  haunts,  as  an  introduc- 
tion to  the  study  of  its  form  and  colors  when  it  is  in  the  aquarium. 

Observations — i.  Where  do  you  find  suckers?  How  do  you  catch 
them?  Do  they  take  the  hook  quickly?  What  is  the  natural  food  of  the 
sucker? 

2.  What  is  the  shape  of  this  fish’s  body  when  seen  from  above? 
From  the  side?  What  is  the  color  above?  On  the  sides?  Below?  Does 
the  sucker  differ  from  most  other  fishes  in  the  coloring  along  its  sides? 
What  is  the  reason  for  this?  What  do  suckers  look  like  on  the  bottom 
of  the  pond  ? Are  they  easily  seen  ? 

3.  Describe  or  sketch  a sucker,  showing  the  position,  size  and  shape 
of  the  fins  and  tail.  Are  its  scales  large  or  small?  How  does  it  use  its 
fins  when  at  rest ? When  moving?  Is  it  a strong  swimmer?  Is  it  a high 
jumper? 

4.  Describe  the  eyes;  how  are  they  especially  adapted  in  position 
and  in  movement  to  the  needs  of  a fish  that  lives  on  the  bottom  of  streams 
and  ponds? 

5.  Note  the  nostrils;  what  is  there  peculiar  about  them? 

6.  Where  is  the  mouth  of  the  sucker  situated?  What  is  its  form ? 
How  is  it  adapted  to  get  the  food  which  the  sucker  likes  best? 

7.  Tell  all  you  know  about  the  habits  of  the  suckers.  When  do  you 
see  them  first  in  the  spring?  Where  do  they  spend  the  winter?  Where 
do  they  go  to  spawn  ? How  large  is  the  largest  one  you  have  ever  seen  ? 
Why  is  their  flesh  usually  considered  poor  in  quality  as  food?  Is  there  a 
difference  in  the  flavor  of  its  flesh  depending  upon  the  locality  in  which 
the  fish  lives ? Why?

THE  SHINER 
Teacher's  Story 

“This  is  a noteworthy  and  characteristic  lineament , or  cipher,  or  hieroglyphic,  or 
type  of  spring.  You  look  into  some  clear,  sandy  bottomed  brook  where  it  spreads  into  a 
deeper  bay,  yet  flowing  cold  from  ice  and  snow  not  far  off,  and  see  indistinctly  poised 
over  the  sand  on  invisible  fins,  the  outlines  of  the  shiner,  scarcely  to  be  distinguished 
from  the  sands  behind  it  as  if  it  were  transparent .” — Thoreau. 

HERE  are  many  species  of  shiners  and  it  is  by  no  means 
easy  to  recognize  them  nor  to  distinguish  them  from 
chub,  dace  and  minnows  since  all  these  belong  to  one 
family;  they  all  have  the  same  arrangement  of  fins  and 
live  in  the  same  water;  and  the  plan  of  this  lesson  can 
with  few  changes  be  applied  to  any  of  them. 

Never  were  seen  more  exquisite  colors  than  shimmer 
along  the  sides  of  the  common  shiner  ( Notropis  cor- 
nutus)  It  is  pale  olive-green  above,  just  a sunny  brook-color,  this  is 
bordered  at  the  sides  by  a line  of  iridescent  blue-purple,  while  the  shining 
silver  scales  on  the  sides  below,  flash  and  glimmer  with  the  changing  hues 
of  the  rainbow.  The  minnows  are  darker  than  the  shiners;  the  horned 
dace  develops  little  tubercles  on  the  head  during  the  breeding  season 
which  are  lost  later. 

The  body  of  the  shiner  is  ideal  for  slipping  through  the  water.  Seen 
from  above  it  is  a narrow^  wedge,  rounded  in  front  and  tapering  to  a point 
behind;  from  the  side,  it  is  long,  oval,  lance-shaped.  The  scales  are  large 


102 


Handbook  of  Nature-Study 


and  beautiful,  the  lateral  line  looks  like  a series  of  dots  embroidered  at  the 
center  of  the  diamond-shaped  scales. 

The  dorsal  fin  is  placed  just  back  of  the  center  of  the  body  and  is  not 
very  large;  it  is  composed  of  soft  rays,  the  first  two  being  stiff  and  un- 
branched. The  tail  is  long,  large,  graceful  and  deeply  notched.  The 
anal  fin  is  almost  as  large  as  the  dorsal.  The  ventral  pair  is  placed  on 
the  lower  side,  opposite  the  dorsal  fin ; the  pectorals  are  set  at  the  lower 
margin  of  the  body,  just  behind  the  gill  openings.  The  shiner  and  its 
relatives  use  the  pectoral  fins  to  aid  in  swimming,  and  keep  them  constantly 
in  motion  when  moving  through  the  water.  The  ventrals  are  moved  only 
now  and  then  and  evidently  help  in  keeping  the  balance.  When  the  fish 
moves  rapidly  forward,  the  dorsal  fin  is  raised  so  that  its  front  edge  stands 
at  right  angles  to  the  body  and  the  ventral  and  anal  fins  are  expanded  to 
their  fullest  extent.  But  when  the  fish  is  lounging,  the  dorsal,  anal  and 
ventral  fins  are  more  or  less  closed,  although  the  tip  of  the  dorsal  fin  swings 
with  every  movement  of  the  fish. 

The  eyes  are  large,  the  pupils  being  very  large  and  black;  the  iris  is 
pale  yellow  and  shining;  the  whole  eye  is  capable  of  much  movement 
forward  and  back.  The  nostril  is  divided  by  a little  projecting  partition 
which  looks  like  a tubercle.  The  mouth  is  at  the  front  of  the  head;  to 
see  the  capabilities  of  this  mouth,  watch  the  shiner  yawn,  if  the  water  of 
the  aquarium  becomes  stale.  Poor  fellow!  He  yawns  just  as  we  do  in 
the  effort  to  get  more  oxygen. 

The  shiners  are  essentially  brook  fish  although  they  may  be  found  in 
larger  bodies  of  water.  They  lead  a precarious  existence,  for  the  larger 
fish  eat  them  in  all  their  stages.  They  only  hold  their  own  by  laying 
countless  numbers  of  eggs.  They  feed  on  water  insects  and  get  even  with 
their  big  fish  enemies  by  eating  their  eggs.  They  are  pretty  and  graceful 
little  creatures  and  may  be  seen  swimming  up  the  current  in  the  middle  of 
the  brook.  They  often  occur  in  schools  or  flocks,  especially  when  young.

LESSON  XXXIX 

The  Shiner 

Leading  thought — The  shiners  are  among  the  most  common  of  the  little 
fish  in  our  small  streams.  They  are  beautiful  in  form  and  play  an 
important  part  in  the  life  of  our  streams. 

Method — Place  in  the  aquarium  shiners  and  as  many  as  possible  of  the 
other  species  of  small  fish  found  in  our  creeks  and  brooks.  The  aquarium 
should  stand  where  the  pupil  may  see  it  often.  The  following  questions 
may  be  asked,  giving  the  children  plenty  of  time  for  the  work  of  observa- 
tion: 

Observations — 1 . Do  you  know  how  the  shiner  differs  in  appearance 
from  the  minnow  and  chub  and  dace  ? 

2.  What  is  the  shape  of  the  shiner’s  body  when  seen  from  above? 
When  seen  from  the  side  ? Do  you  think  that  its  shape  fits  it  for  moving 
rapidly  through  the  water? 

3.  What  is  the  coloring  above ? On  the  sides?  Below? 

4.  Are  the  scales  large  and  distinct,  or  very  small?  Can  you  see  the 
lateral  line  ? Where  are  the  tiny  holes,  which  make  this  line,  placed  in  the 
scales  ? 

5.  Describe  or  sketch  the  fish,  showing  position,  relative  size  and 
shape  of  all  the  fins  and  the  tail. 

6.  Describe  the  use  and  movements  of  each  of  the  fins  when  the  fish 
is  swimming. 

7.  Describe  the  eyes.  Do  they  move? 

8.  Describe  the  nostrils.  Do  you  think  each  one  is  double? 

9.  Does  the  mouth  open  upwards,  downwards  or  forwards?  Have 
you  ever  seen  the  shiner  yawn  ? Why  does  it  yawn  ? Why  do  you  yawn  ? 

10.  Where  do  you  find  the  shiners  living?  Do  they  haunt  the 
middle  of  the  stream  or  the  edges?  Do  you  ever  see  them  in  flocks  or 
schools  ? 


MINNOWS 

How  silent  comes  the  water  round  that  bend; 

Not  the  minutest  whisper  does  it  send 
To  the  o'er  hanging  sallows;  blades  of  grass 
Slowly  across  the  chequer'd  shadows  pass, 

Why,  you  might  read  two  sonnets,  ere  they  reach 
To  where  the  hurrying  freshnesses  aye  preach 
A natural  sermon  o'er  their  pebbly  beds; 

Where  swarms  of  minnows  show  their  little  heads , 

Staying  their  wavy  bodies  'gainst  the  streams. 

To  taste  the  luxury  of  sunny  beams 
Tempered  with  coolness.  How  they  ever  wrestle 
With  their  own  sweet  delight,  and  ever  nestle 
Their  silver  bellies  on  the  pebbly  sand! 

If  you  but  scantily  hold  out  the  hand. 

That  very  instant  not  one  will  remain; 

But  turn  your  eye,  and  there  they  are  again. 

The  ripples  seem  right  glad  to  reach  those  cresses. 

And  cool  themselves  among  the  em'rald  tresses; 

The  while  they  cool  themselves,  they  freshness  give, 

And  moisture,  that  the  bowery  green  may  live. 

— John  Keats.

THE  BROOK  TROUT 

T eacher’s  Story 


“ Up  and  down  the  brook  I ran,  where  beneath  the  banks  so  steep , 

Lie  the  spotted  trout  asleep.'” — Whittier. 

UT  they  were  probably  not  asleep  as  Mr.  Whittier  might 
have  observed  if  he  had  cast  a fly  near  one  of  them. 
There  is  in  the  very  haunts  of  the  trout,  a suggestion  of 
where  it  gets  its  vigor  and  wariness:  The  cold,  clear 

streams  where  the  water  is  pure;  brooks  that  wind  in 
and  out  over  rocky  and  pebbly  beds,  here  shaded 
by  trees  and  there  dashing  through  the  open, — it  makes 
us  feel  vigorous  even  to  think  of  such,  streams.  Under  the  overhanging 
bank  or  in  the  shade  of  some  fallen  log  or  shelving  rock,  the  brook  trout 
hides  where  he  may  see  all  that  goes  on  in  the  world  above  and  around 
him  without  being  himself  seen.  Woe  to  the  unfortunate  insect  that  falls 
upon  the  surface  of  the  water  in  his  vicinity  or  even  that  flies  low  over  the 
surface  for  the  trout  will  jump  easily  far  out  of  the  water  to  seize  its  prey! 
It  is  this  habit  of  taking  the  insect  upon  and  above  the  water’s  surface 
which  has  made  trout  fly-fishing  the  sport  that  it  is.  Man’s  ingenuity  is 
fairly  matched  against  the  trout’s  cunning  in  this  contest.  I know  of  one 
old  trout  that  has  kept  fishermen  in  the  region  around  on  the  qui  vive  for 
years;  and  up  to  date  he  is  still  alive,  making  a dash  now  and  then  at  a 
tempting  bait,  showing  himself  enough  to  tantalize  his  would-be  captors 
with  his  splendid  size,  but  always  retiring  at  the  sight  of  the  line. 

The  brook  trout  varies  much  in  color,  depending  upon  the  soil  and  the 
rocks  of  the  streams  in  which  it  lives.  Its  back  is  marbled  with  dark 
olive  or  black,  making  it  just  the  color  of  shaded  water.  This  marbled 
coloration  also  marks  the  dorsal  and  the  tail  fins.  The  sides,  which  vary 
much  in  color,  are  marked  with  beautiful  vermilion  spots,  each  placed  in 
the  center  of  a larger,  brownish  spot.  In  some  instances  the  lower  surface 


Fish  Study

is  reddish,  in  others  whitish.  All  the  fins  on  the  lower  side  of  the  body 
have  the  front  edges  creamy  or  yellowish  white,  with  a darker  streak 
behind. 

The  trout’s  head  is  quite  large  and  somewhat  blunt.  The  large  eye  is 
a little  in  front  of  the  middle  of  the  head.  The  dorsal  fin  is  at  about  the 
middle  of  the  body,  and  when  raised  is  squarish  in  outline.  Behind  the 
dorsal  fin,  and  near  to  the  tail  is  the  little,  fleshy  adipose  fin,  so  called 
because  it  has  no  rays.  The  tail  is  fan-shaped,  slightly  notched  at  the  end 
and  is  large  and  strong.  The  anal  fin  is  rather  large,  being  shaped  much 
like  the  dorsal  fin,  only  slightly  smaller.  The  ventral  fins  are  directly 
below  the  dorsal  fin  and  a little  behind  its  middle.  The  pectorals  are 
low  down,  being  below  and  just  behind  the  gill  arches. 


In  size  the  brook  trout  seldom  is  longer  than  seven  or  eight  inches,  but 
in  the  rivers  of  the  Northeastern  United  States  specimens  weighing  from 
six  to  eleven  pounds  are  sometimes  taken.  It  does  not  flourish  in  water 
which  is  warmer  than  68°,  but  prefers  a temperature  of  about  50°.  It 
must  have  the  pure  water  of  mountain  streams  and  cannot  endure  water 
of  rivers  which  is  polluted  by  mills  or  the  refuse  of  cities.  Where  it  has 
access  to  streams  that  flow  into  the  ocean,  it  forms  the  salt  water  habit, 
going  out  to  sea  and  remaining  there  during  the  winter.  Such  specimens 
become  very  large. 

The  trout  can  lay  eggs  when  about  six  inches  in  length.  The  eggs  are 
laid  from  September  until  late  November,  although,  as  Mr.  Bream  says, 
the  brook  trout  are  spawned  at  some  locality  in  almost  every  month  of  the 
year  except  mid-summer.  One  mother  trout  lays  from  400  to  600  eggs, 
but  the  large-sized  ones  lay  more.  The  period  of  hatching  depends  upon 
the  temperature  of  the  water.  In  depositing  their  eggs  the  trout  seek 
water  with  gravelly  bottom,  often  where  some  mountain  brook  opens  into 


Where  the  trout  hide.

a larger  stream.  The  nest  is  shaped  by  the  tail  of  the  fish,  the  larger 
stones  being  carried  away  in  the  mouth.  To  make  the  precious  eggs 
secure  they  are  covered  with  gravel. 

There  have  been  strict  laws  enacted  by  almost  all  of  our  states  with 
a view  to  protecting  the  brook  trout  and  preserving  it  in  our  streams. 
The  open  season  in  New  York  is  from  the  15th  of  April  to  the  1st  of  Sep- 
tember, and  it  is  illegal  to  take  from  a stream  a fish  that  is  less  than  five 
inches  in  length.  It  is  the  duty  of  every  decent  citizen  to  abide  by  these 
laws  and  to  see  to  it  that  his  neighbors  observe  them.  The  teacher  cannot 
emphasize  enough  upon  the  child  the  moral  value  of  being  law-abiding. 
There  should  be  in  every  school  in  the  Union  children's  clubs  which  should 
have  for  their  purpose  civic  honesty  and  the  enforcement  of  laws  which 
affect  the  city,  village  or  township. 

Almost  any  stream  with  suitable  water  may  be  stocked  with  trout  from 
the  national  or  the  state  hatcheries,  but  what  is  the  use  of  this  expense  if 
the  game  laws  are  not  observed  and  these  fish  are  caught  before  they  reach 
maturity,  as  is  so  often  the  case?

LESSON  XL 
The  Brook  Trout 

Leading  thought — The  brook  trout  have  been  exterminated  in  our 
streams  largely  because  the  game  laws  have  not  been  observed.  The 
trout  is  the  most  cunning  and  beautiful  of  our  common  fishes  and  the  most 
valuable  for  food.  If  properly  guarded,  every  pure  mountain  stream  in 
our  country,  could  be  well  stocked  with  the  brook  trout. 

Method — A trout  may  be  kept  in  an  aquarium  of  flowing  water  in- 
definitely and  should  be  fed  upon  liver  and  hard  clams  chopped.  If  there 
is  no  aquarium  with  running  water,  the  trout  may  be  kept  in  an  ordinary 
jar  long  enough  for  this  lesson.  The  object  of  this  lesson  should  be  not 
only  the  study  of  the  habits  of  the  fish,  but  also  a lesson  in  its  preserva- 
tion. 

Observations — 1.  In  what  streams  are  the  brook  trout  found? 

Must  the  water  be  warm  or  cold?  Can  the  trout  live  in  impure  water? 
Can  it  live  in  salt  water? 

2.  Do  the  trout  swim  about  in  schools  or  do  they  live  solitary? 
Where  do  they  like  to  hide? 

3.  With  what  kind  of  bait  is  trout  caught?  Why  does  it  afford 
such  excellent  sport  for  fly-fishing?  Can  you  tell  what  the  food  of  the 
trout  is  ? 

4.  What  is  the  color  of  the  trout  above?  Wrhat  colors  along  its 
sides?  What  markings  make  the  fish  so  beautiful?  What  is  its  color 
below  ? Has  the  trout  scales  ? Do  you  see  the  lateral  line  ? 

5.  What  is  the  general  shape  of  the  brook  trout?  Describe  the 
shape,  position  and  color  of  the  dorsal  fin.  Describe  the  little  fin  behind 
the  dorsal.  Why  is  it  unlike  the  other  fins?  What  is  the  shape  of  the 
tail  fin?  Is  it  rounded,  square  or  crescent-shaped  across  the  end?  What 
is  the  position  and  size  of  the  anal  fin  compared  with  the  dorsal?  What 
colors  on  the  ventral  fins  and  where  are  they  placed  in  relation  to  the 


Fish  Study  167 

dorsal  fin?  What  color  are  the  pectoral  fins  and  how  are  they  placed  in 
relation  to  the  gill  arches? 

6.  Describe  the  trout’s  eyes.  Are  they  large  and  alert?  Do  you 
think  the  trout  is  keen-sighted? 

7.  When  and  where  are  the  eggs  laid?  Describe  how  the  nest  is 
made.  How  are  the  eggs  covered  and  protected  ? 

8.  Why  are  there  no  trout  in  the  streams  of  your  neighborhood? 
Could  a trout  live  in  these  streams?  Can  you  get  state  aid  in  stocking  the 
streams? 

9.  What  are  the  game  laws  concerning  trout  fishing?  When  is  the 
open  season?  How  long  must  the  trout  be  to  be  taken  legally?  If  you 
are  a good  citizen  what  do  you  do  about  the  game  laws? 

10.  Write  a story  telling  all  you  know  about  the  wariness,  cunning 
and  strength  of  the  brook  trout.

TROUT 

“ It  is  well  for  anglers  not  to  make  trout,  of  all  fishes,  the  prime  objective  of  a day’s 
sport , as  no  more  uncertain  game  loves  the  sunlight.  Today  he  is  yours  for  the  very 
asking , tomorrow,  the  most  luscious  lure  will  not  tempt  him.  One  hour  he  defies  you, 
the  next,  gazes  at  you  from  some  ensconcement  of  the  fishes,  and  knows  you  not,  as  you 
pass  him,  casting,  by. 

I believe  I accumulated  some  of  this  angling  wisdom  years  ago,  in  a certain  trout 
domain  in  New  England,  where  there  were  streams  and  pools,  ripples,  cascades  and 
drooping  trees;  where  everything  was  fair  and  promising  to  the  eyes  for  trout;  but  it 
required  superhuman  patience  to  lure  them,  and  many  a day  I scored  a blank.  Yet  on 
these  very  days  when  lures  were  unavailing,  the  creel  empty  save  for  fern  leaves,  I found 
they  were  not  for  naught;  that  the  real  fishing  day  ivas  a composite  of  the  weather,  the 
wind,  even  if  it  was  from  the  east,  the  splendid  colors  of  forest  trees,  the  blue  tourmaline 
of  the  sky  that  topped  the  stream  amid  the  trees,  the  flecks  of  cloud  mirrored  on  the  sur- 
face. The  delight  of  anticipation,  the  casting,  the  play  of  the  rod,  the  exercise  of  skill,  the 
quick  turns  in  the  steam  opening  up  new  vistas,  the  little  openings  in  the  forest,  through 
which  were  seen  distant  meadows  and  nodding  flowers — all  these  went  to  make  up  the  real 
trout  fishing,  the  actual  catch  being  but  an  incident  among  many  delights. 

Just  how  long  one  could  be  content  with  mere  scenery  in  lieu  of  trout,  I am  not  pre- 
pared to  say;  if  pushed  to  the  wall,  I confess  that  when  fishing  l prefer  trout  to  scenic 
effects.  Still,  it  is  a very  impracticable  and  delightful  sentiment  with  some  truth  to  it, 
the  moral  being  that  the  angler  should  be  resourceful,  and  not  be  entirely  cast  down  on  the 
days  when  the  wind  is  in  the  cast 

/ am  aware  that  this  method  of  angling  is  not  in  vogue  with  some,  and  would  be 
deemed  fanciful,  indeed  inane,  by  many  more;  yet  it  is  based  upon  a true  and  homely 
philosophy,  not  of  today,  the  philosophy  of  patience  and  contentment.  “How  poor  are 
they  that  have  not  patience,"  said  Othello.  It  is  well  to  be  content  with  things  as  we  find 
them,  and  it  is  well  to  go  a-fishing,  not  to  catch  fish  alone,  but  every  offering  the  day  has 
to  give.  This  should  be  an  easy  matter  for  the  angler,  as  Walton  tells  us  that  Angling  is 
somewhat  like  poetry,  men  are  10  be  born  so"

THE  STICKLEBACK 
Teacher's  Story 

IS  is  certainly  the  most  sagacious  of  the 
Lilliputian  vertebrates;  scarcely  more 
than  an  inch  in  length  when  full-grown,  it 
gazes  at  you  with  large,  keen,  shining- 
rimmed  eyes,  takes  your  measure  and 
darts  off  with  a flirt  of  the  tail  that  says 
plainly,  “Catch  me  if  you  can.”  The 
sticklebacks  are  delightful  aquarium  pets 
because  their  natural  home  is  in  still 
water  sufficiently  stagnant  for  algas  to 
grow  luxuriously;  thus  we  but  seldom 
need  to  change  the  water  in  the  aquari- 
um, which,  however,  should  be  well 
stocked  with  water  plants  and  have  gravel 
at  the  bottom. 

When  the  stickleback  is  not  resting  he 
is  always  going  somewhere  and  he 
knows  just  where  he  is  going  and  what  he 
is  going  to  do,  and  earthquakes  shall  not 
deter  him.  He  is  the  most  dynamic 
creature  in  all  creation,  I think,  except  perhaps  the  dragon  fly,  and 
he  is  so  ferocious  that  if  he  were  as  large  as  a shark  he  would  destroy  all 
other  fishes.  Place  an  earthworm,  cut  into  small  sections,  in  the  aquari- 
um and  while  each  section  is  wriggingly  considering  whether  it  may  be 
able  to  grow  both  ends  into  another  worm , the  stickleback  takes  hold 
with  a will  and  settles  the  matter  in  the  negative.  His  ferocity  is 
frightful  to  behold  as  he  seizes  his  prey  and  shakes  it  as  a terrier  does  a rat. 

Well  is  this  fish  named  stickleback,  for  along  the  ridge  of  its  back  are 
sharp,  strong  spines — five  of  them  in  our  tiny,  brook  species.  These 
spines  may  be  laid  back  flat  or  they  may  be  erected  stiffly,  making  an 
efficient  saw  which  does  great  damage  to  fish  many  times  larger  than  the 
stickleback.  When  we  find  the  minnows  in  the  aquarium  losing  their 
scales  we  may  be  sure  they  are  being  raked  off  by  this  saw-back;  and  if 
the  shiner  or  sunfish  undertakes  to  make  a stickleback  meal,  there  is 
only  one  way  to  do  it,  and  that  is  to  catch  the  quarry  by  the  tail,  since  he  is 
too  alert  to  be  caught  in  any  other  way.  But  swallowing  a stickleback 
tail  first  is  a dangerous  performance,  for  the  sharp  spines  rip  open  the 
throat  or  stomach  of  the  captor.  Dr.  Jordan  says  that  the  sticklebacks 
of  the  Puget  Sound  region  are  called  “salmon  killers”  and  that  they  well 
earn  the  name;  these  fierce  midgets  unhesitatingly  attack  the  salmon, 
biting  off  pieces  of  their  fins  and  also  destroying  their  spawn. 

As  seen  from  the  side,  the  stickleback  is  slender  and  graceful,  pointed 
like  an  arrow  at  the  front  end,  and  with  the  body  behind  the  dorsal  fin 
forming  a long  and  slender  pedicel  to  support  the  beautifully  rounded  tail 
fin.  The  dorsal  fin  is  placed  well  back  and  is  triangular  in  shape;  the 
anal  fin  makes  a similar  triangle  opposite  it  below  and  has  a sharp  spine 
at  its  front  edge.  The  color  of  the  body  varies  with  the  light;  when 
floating  among  the  water  weed  the  back  is  greenish  mottled  with  paler 
green,  but  when  the  fish  is  down  on  the  gravel  it  is  much  darker.  The 
lateral  line  is  marked  by  a rather  broad  silver  stripe.

If  large  eyes  count  for  beauty,  then  the  stickleback  deserves  “the 
apple,”  for  its  eyes  are  not  only  large  but  gemlike,  with  a broad  iris  of 
golden  brown  around  the  black  pupil.  I am  convinced  that  the  stickle- 
back has  a keener  vision  than  most  fish;  it  can  move  its  eyes  backward 
and  forward  rapidly  and  alertly.  The  mouth  opens  almost  upward  and 
is  a wicked  little  mouth,  both  in  appearance  and  action. 

When  swimming,  the  stickleback  darts  about  rapidly,  its  dorsal  and 
anal  fins  extended,  its  spines  all  abristle,  its  tail  lashing  the  water  with 
strong  strokes  and  the  pectorals  flying  so  fast  that  they  make  a blur;  the 
ventral  fins  are  rarely  extended,  in  fact  they  are  nothing  but  two  little 
spines.  When  the  fish  wishes  to  lift  itself  through  the  water  it  seems  to 
depend  entirely  upon  its  pectoral  fins  and  these  are  also  used  for  balanc- 
ing. Its  favorite  position  is  hanging  motionless  among  the  pond  weeds, 
with  the  tail,  the  dorsal  and  ventral  fins  partially  closed;  it  usually  rests 
upon  the  pectoral  fins  which  are  braced  against  some  stem;  in  one  case  I 
saw  the  ventrals  and  pectorals  used  together  to  clasp  a stem  and  hold  the 
fish  in  place.  In  moving  backward  the  pectorals  do  the  work,  with  a 
little  beckoning  motion  of  the  tail  occasionally.  When  resting  upon  the 
bottom  of  the  aquarium,  it  closes  its  fins  and  makes  itself  quite  incon- 
spicuous. It  can  dig  with  much  power  accomplishing  this  by  a comical 
augerlike  motion;  it  plunges  head  first  into  the  gravel  and  then  by 
twisting  the  body  and  tail  around  and  around,  it  soon  forms  a hiding 
.place. 

But  it  is  as  a house  builder  and  father  and  home  protector  that  the 
stickleback  shines.  In  the  early  spring  he  builds  him  a nest  made  from 
the  fine  green  algae  called  frog-spittle.  This  would  seem  a too  delicate 
material  for  the  house  construction,  but  he  is  a clever  builder.  He  fastens 
his  filmy  walls  to  some  stems  of  reed  or  grass,  using  as  a platform 
a supporting  stem;  the  ones  which  I have  especially  studied  were  fastened 
to  grass  stems.  The  stickleback  has  a little  cement  plant  of  his  own,  sup- 
posed to  be  situated  in  the  kidneys,  which  at  this  time  of  year  secrete  the 
glue  for  building  purposes.  The  glue  is  waterproof.  It  is  spun  out  in 
fine  threads  or  in  filmy  masses  through  an  opening  near  the  anal  fin. 
One  species  weights  his  platform  with  sand  which  he  scoops  up  from  the 
bottom,  but  I cannot  detect  that  our  brook  stickleback  does  this.  In  his 
case,  home  is  his  sphere  literally,  for  he  builds  a spherical  house  about  the 
size  of  a glass  marble,  three-quarters  of  an  inch  in  diameter;  it  is  a hollow 
sphere  and  he  cements  the  inside  walls  so  as  to  hold  them  back  and  give 
room,  and  he  finishes  his  pretty  structure  with  a circular  door  at  the  side. 
When  finished,  the  nest  is  like  a bubble,  made  of  threads  of  down  and  yet 
it  holds  together  strongly. 

In  the  case  of  the  best  known  species,  the  male,  as  soon  as  he  has 
finished  his  bower  to  his  satisfaction,  goes  a-wooing;  he  selects  some  lady 
stickleback,  and  in  his  own  way  tells  her  of  the  beautiful  nest  he  has  made 
and  convinces  her  of  his  ability  to  take  care  of  a family.  He  certainly  has 
fetching  ways  for  he.  soon  conducts  her  to  his  home.  She  enters  the  nest 
through  the  little  circular  door,  lays  her  eggs  within  it,  and  then  being  a 
flighty  creature,  she  sheds  responsibilities  and  flits  off  care  free.  He 
follows  her  into  the  nest,  scatters  the  fertilizing  milt  over  the  eggs  and 
then  starts  off  again  and  rolls  his  golden  eyes  on  some  other  lady  stickle- 
back and  invites  her  also  to  his  home;  she  comes  without  any  jealousy 
because  she  was  not  first  choice,  and  she  also  enters  the  nest  and  lays  her

eggs  and  then  swims  off  unconcernedly.  Again  he  enters  the  nest  and 
drops  more  milt  upon  the  eggs  and  then  fares  forth  again,  a still  energetic 
wooer.  If  there  was  ever  a justified  polygamist,  he  is  one,  since  it  is  only 
the  cares  and  responsibilities  of  the  home  that  he  desires.  He  only  stops 
wooing  when  his  nest  holds  as  many  eggs  as  hs  feels  equal  to  caring  for. 
He  now  stands  on  guard  by  the  door,  and  with  his  winnowing  pectoral 
fins,  sets  up  a current  of  water  over  the  eggs;  he  drives  off  all  intruders 
with  the  most  vicious  attacks,  and  keeps  off  many  an  enemy  simply  by 
a display  of  reckless  fury;  thus  he  stands  guard  until  the  eggs  hatch  and 
the  tiny  little  sticklebacks  come  out  of  the  nest  and  float  off,  attaching 
themselves  by  their  mouths  to  the  pond  weeds  until  they  become  strong 
enough  to  scurry  around  in  the  water. 


Some  species  arrange  two 
doors  in  this  spherical  nest 
so  that  a current  of  water 
can  flow  through  and  over 
the  eggs.  Mr.  Eugene  Bark- 
er, who  has  made  a special 
study  of  the  little  five- 
spined  sticklebacks  of  the 
Cayuga  Basin,  has  failed  to 
find  more  than  one  door  to 
their  nests.  Mr.  Barker 
made  a most  interesting  ob- 
servation on  this  stickle- 
back’s obsession  for  father- 
hood. He  placed  in  the 
aquarium  two  nests,  one  of 
which  was  guarded  by  its 
loyal  builder,  which  allowed 
himself  to  be  caught  rather 
than  desert  his  post;  the 
little  guardian  soon  dis- 
covered the  unprotected  nest  and  began  to  move  the  eggs  from  it  to 
his  own,  carrying  them  carefully  in  his  mouth.  This  addition  made  his 
own  nest  so  full  that  the  eggs  persistently  crowded  out  of  the  door,  and 
he  spent  much  of  his  time  nudging  them  back  with  his  snout.  We  saw 
this  stickleback  fill  his  mouth  with  algae  from  the  bottom  of  the 
aquarium,  and  holding  himself  steady  a short  distance  away,  apparent- 
ly blow  the  algae  at  the  nest  from  a distance  of  half  an  inch,  and  we 
wondered  if  this  was  his  method  of  laying  on  his  building  materials 
before  he  cemented  them. 

The  eggs  of  this  species  are  white  and  shining  like  minute  pearls,  and 
seem  to  be  fastened  together  in  small  packages  with  gelatinous  matter. 
The  mating  habits  of  this  species  have  not  been  thoroughly  studied ; there- 
fore,'here  is  an  opportunity  for  investigation  on  the  part  of  the  boys  and 
girls.

LESSON  XLI 

The  Stickleback 

Leading  thought — The  stickleback  is  the  smallest  of  our  common  fish. 
It  lives  in  stagnant  water.  The  father  stickleback  builds  his  pretty  nest 
of  frog-spittle  which  he  watches  very  carefully. 

Method — To  find  sticklebacks  go  to  a pond  of  stagnant  water  which 
does  not  dry  up  during  the  year.  If  it  is  partly  shaded  by  bushes  so  much 
the  better.  Take  a dip  net  and  dip  deeply ; carefully  examine  all  the  little 
fish  in  the  net  by  putting  them  in  a Mason  jar  of  water  so  that  you  can  see 
what  they  are  like.  The  stickleback  is  easily  distinguished  by  the  five 
spines  along  its  back.  If  you  collect  these  fish  as  early  as  the  first  of  May 
and  place  several  of  them  in  the  aquarium  with  plenty  of  the  algae  known 
as  frog-spittle  and  other  water  plants  they  may  perhaps  build  a nest  for 
you.  They  may  be  fed  upon  bits  of  meat  or  liver  chopped  very  fine  or 
upon  earthworms  cut  into  small  sections. 

Observations — 1.  How  did  the  stickleback  get  its  name?  How 
many  spines  has  ib?  Where  are  they  situated  ? Are  they  always  carried 
erect?  How  are  these  spines  used  as  weapons?  How  do  they  act  as  a 
means  of  safety  to  the  stickleback? 

2.  Describe  or  make  a sketch  showing  the  shape  and  position  of  the 
dorsal,  the  anal,  the  ventral  and  the  pectoral  fins.  What  is  the  shape  of 
the  tail?  What  is  the  general  shape  of  the  fish? 

3.  What  is  the  color  of  the  sticklebacks?  Is  the  color  always  the 
same?  What  is  the  color  and  position  of  the  lateral  line? 

4.  Describe  the  eyes.  Are  they  large  or  small?  Can  they  be 
moved?  Do  you  think  they  can  see  far? 

5.  Describe  the  mouth.  Does  it  open  upward,  straight  ahead  or 
downward  ? 

6.  When  the  stickleback  is  swimming  what  are  the  positions  and 
motions  of  the  dorsal,  anal,  tail  and  pectoral  fins?  Can  you  see  the 
ventral  pair?  Are  they  extended  when  the  fish  is  swimming? 

7.  When  resting  among  the  pond  weed  of  the  aquarium  what  fins 
does  the  stickleback  use  for  keeping  afloat  ? How  are  the  other  fins  held  ? 
What  fins  does  it  use  to  move  backward?  Which  ones  are  used  when  it 
lifts  itself  from  the  bottom  to  the  top  of  the  aquarium?  How  are  its  fins 
placed  when  it  is  at  rest  on  the  bottom? 

8.  Drop  a piece  of  earthworm  or  some  liver  or  fresh  meat  cut  finely 
into  the  aquarium  and  describe  the  action  of  the  sticklebacks  as  they  eat 
it.  How  large  is  a full-grown  stickleback? 

9.  In  what  kind  of  ponds  do  we  find  sticklebacks?  Do  you  know 
how  the  stickleback  nest  looks?  Of  what  is  it  built?  How  is  it  sup- 
ported? Is  there  one  door  or  two?  Does  the  father  or  mother  stickle- 
back build  the  nest?  Are  the  young  in  the  nest  cared  for?  At  what 
time  is  the  nest  built?

The  sunfish  likes  quiet  waters  for  nesting. 

THE  SUNFISH 
Teacher's  Story 

HIS  little  disc  of  gay  color  has  won  many  popular  names. 
It  is  called  pumpkin  seed,  tobacco  box  and  sunfish 
because  of  its  shape,  and  it  is  also  called  bream  and 
pond  fish.  I have  always  wondered  that  it  was  not 
called  chieftain  also,  for  when  it  raises  its  dorsal  fin 
with  its  saw  crest  of  spines,  it  looks  like  the  head-dress 
of  an  Indian  chief;  and  surely  no  warrior  ever  had  a 
greater  enjoyment  in  a battle  than  does  this  indom- 
itable little  fish. 

The  sunfish  lives  in  the  eddies  of  our  clear  brooks  and  ponds.  It  is  a 
near  relative  to  the  rock  bass  and  also  of  the  black  bass  and  it  has,  accord- 
ing to  its  size,  just  as  gamey  qualities  as  the  latter.  I once  had  a sunfish 
on  my  line  which  made  me  think  I had  caught  a bass  and  I do  not  know 
whether  I or  the  mad  little  pumpkin  seed  was  the  most  disgusted  when  I 
discovered  the  truth.  I threw  him  back  in  the  water  but  his  fighting 
spirit  was  up,  and  he  grabbed  my  hook  again  within  five  minutes,  which 
showed  that  he  had  more  courage  than  wisdom;  it  would  have  served  him 
right  if  I had  fried  him  in  a pan,  but  I never  could  make  up  my  mind  to 
kill  a fish  for  the  sake  of  one  mouthful  of  food. 

Perhaps  of  all  its  names,  “pumpkin  seed”  is  the  most  graphic,  for  it 
resembles  this  seed  in  the  outlines  of  its  body  when  seen  from  the  side. 
Looked  at  from  above,  it  has  the  shape  of  a powerful  craft  with  smooth.

rounded  nose  and  gently  swelling  and  tapering  sides ; it  is  widest  at  the 
eyes  and  this  is  a canny  arrangement,  for  these  great  eyes  turn  alertly  in 
every  direction;  and  thus  placed  they  are  able  to  discern  the  enemy  or 
the  dinner  coming  from  any  quarter. 

The  dorsal  fin  is  a most  militant  looking  organ.  It  consists  of  ten 
spines,  the  hind  one  closely  joined  to  the  hind  dorsal  fin,  which  is  sup- 
ported by  the  soft  rays.  The  three  front  spines  rise  successively,  one 
above  another  and  all  are  united  by  the  membrane,  the  upper  edge  of 
which  is  deeply  toothed.  The  hind  dorsal  fin  is  gracefully  rounded  and 
the  front  and  hind  fin  wo^k  independently  of  each  other,  the  latter  often 
winnowing  the  water  when  the  former  is  laid  flat.  The  tail  is  strong  and 
has  a notch  in  the  end ; the  anal  fin  has  three  spines  on  its  front  edge  and 


ten  soft  rays.  Each  ventral  fin  also  has  a spine  at  the  front  edge  and  is 
placed  below  and  slightly  behind  the  pectorals.  The  pectoral  fins,  I have 
often  thought,  were  the  most  exquisite  and  gauzelike  in  texture  of  any 
fins  I have  ever  seen;  they  are  kept  almost  constantly  in  motion  and 
move  in  such  graceful  flowing  undulations  that  it  is  a joy  to  look  at  them. 

The  eye  of  the  sunfish  is  very  large  and  quite  prominent;  the  large 
black  pupil  is  surrounded  by  an  iris  that  has  shining  lavender  and  bronze 
in  it,  but  is  more  or  less  clouded  above ; the  young  ones  have  a pale  silver 
iris.  The  eyes  move  in  every  direction  and  are  eager  and  alert  in  their 
expression.  The  mouth  is  at  the  front  of  the  body  but  it  opens  upward. 
The  gill  opening  is  prolonged  backward  at  the  upper  comer,  making  an 
earlike  flap;  this,  of  course,  has  nothing  to  do  with  the  fish’s  ears,  but  it  is 
highly  ornamental  as  it  is  greenish-black  in  color,  bordered  by  iridescent, 
pale  green,  with  a brilliant  orange  spot  on  its  hind  edge.  The  colors  of 
the  sunfish  are  too  varied  for  description  and  too  beautiful  to  reduce  to 
mere  words.  There  are  dark,  dull,  greenish  or  purplish  cross-bands 
worked  out  in  patterns  of  scale-mosaic,  and  between  them  are  bands  of 
pale  iridescent-green,  set  with  black-edged  orange  spots.  But  just  as  we 


174 


Handbook  of  Nature-Study 


have  described  his  colors  our  sunfish  darts  off  and  all  sorts  of  shimmering, 
shining  blue,  green  and  purple  tints  play  over  his  body  and  he  settles  down 
into  another  comer  of  the  aquarium,  and  his  colors  seem  much  paler  and 
we  have  to  describe  him  over  again.  The  body  below  is  brassy-yellow. 

The  beautiful  colors  which  the  male  sunfish  dons  in  spring,  he  puts  at 
once  to  practical  use.  Professor  Reighard  says  that  when  courting  and 
trying  to  persuade  his  chosen  one  to  come  to  his  nest  and  there  deposit 
her  eggs,  he  faces  her,  with  his  gill  covers  puffed  out,  the  scarlet  or  orange 
spot  on  the  ear-flap  standing  out  bravely,  and  his  black  ventral  fins  spread 
wide  to  show  off  their  patent-leather  finish.  Thus,  does  he  display  him- 
self before  her  and  persuade  her;  but  he  is  rarely  allowed  to  do  this  in 
peace.  Other  males  as  brilliant  as  he  arrive  on  the  scene  and  he  must 
forsooth  stop  parading  before  his  lady  love  in  order  to  fight  his  rival,  and 


Male  of  the  sunfish  guarding  his  nest. 
After  Gill 


he  fights  with  as  much  display  of  color  as  he  courts.  But  in  the  sunfish 
duel  the  participants  do  not  seek  to  destroy  each  other  but  to  mutilate 
spitefully  each  other’s  fins.  The  vanquished  one  with  his  fins  all  tom  retires 
from  the  field.  Professor  Gill  says:  “Meanwhile  the  male  has  selected  a 
spot  in  very  shallow  water  near  the  shore,  and  generally  in  a mass  of 
aquatic  vegetation,  not  too  large  or  close  together  to  entirely  exclude  the 
light  and  heat  of  the  sun,  and  mostly  under  an  over-hanging  plant.  The 
choice  is  apt  to  be  in  some  general  strip  of  shallow  water  close  by  the  shore 
which  is  favored  by  many  others  so  that  a number  of  similar  nests  may 
be  found  close  together,  although  never  encroaching  on  each  other. 
Each  fish  slightly  excavates  and  makes  a saucer-like  basin  in  the  chosen 
area  which  is  carefully  cleared  of  all  pebbles.  Such  are  removed  by 
violent  jerks  of  the  caudal  fin  or  are  taken  up  by  the  mouth  and  carried  to 
the  circular  boundary  of  the  nest.  An  area  of  fine,  clean  sand  or  gravel  is 
generally  the  result,  but  not  infrequently,  according  to  Dr.  Reighard,  the 


Fish  Study 


*75 


nest  bottom  is  composed  of  the  rootlets  of  water  plants.  The  nest  has 
a diameter  of  about  twice  the  length  of  the  fish.” 

On  the  nest  thus  formed,  the  sunfish  belle  is  invited  to  deposit  her 
eggs,  which  as  soon  as  laid  fall  to  the  bottom  and  become  attached 
to  the  gravel  at  the  bottom  of  the  nest  by  the  viscid  substance 
which  surrounds  them.  Her  duty  is  then  done  and  she  departs, 
leaving  the  master  in  charge  of  his  home  and  the  eggs.  If  truth  be  told, 
he  is  not  a strict  monogamist.  Professor  Reighard  noticed  one  of  these 
males  which  reared  in  one  nest  two  broods  laid  at  quite  different 
times  by  two  females.  For  about  a week,  depending  upon  the  tem- 
perature, the  male  is  absorbed  in  his  care  of  the  eggs  and  defends  his  nest 
with  much  ferocity,  but  after  the  eggs  have  hatched  he  considers  his  duty 
done  and  lets  his  progeny  take  care  of  themselves  as  best  they  may. 

Sunfish  are  easily  taken  care  of  in  an  aquarium,  but  each  should  be 
kept  by  himself  as  they  are  likely  to  attack  any  smaller  fish  and  are  most 
uncomfortable  neighbors.  I have  kept  one  of  these  beautiful,  shimmer- 
ing pumpkin  seeds  for  nearly  a year,  by  feeding  him  every  alternate  day 
with  an  earthworm ; these  unfortunate  creatures  are  kept  stored  in  damp 
soil  in  an  iron  kettle  during  the  winter.  When  I threw  one  of  them  into 
the  aquarium  he  would  seize  it  and  shake  it  as  a terrier  shakes  a rat ; but 
this  was  perhaps  to  make  sure  of  his  hold.  Once  he  attempted  to  take  the 
second  worm  directly  after  the  first;  but  it  was  a doubtful  proceeding, 
and  the  worm  reappeared  as  often  as  a prim  a donna,  waving  each  time  a 
frenzied  farewell  to  the  world. 

LESSON  XLI 
The  Sunfish 

Leading  thought — The  pumpkin  seeds  are  very  gamey  little  fishes 
which  seize  the  hook  with  much  fierceness.  They  live  in  the  still  waters 
of  our  streams  or  in  ponas  and  build  nests  in  the  spring,  in  which  the  eggs 
are  laid  and  which  they  defend  valiantly. 

Method — The  common  pumpkin  seed  in  the  jar  aquarium  is  all  that  is 
necessary  for  this  lesson.  However,  it  will  add  much  to  the  interest  of 
the  lesson  if  the  boys  who  have  fished  for  pumpkin  seeds  will  tell  of  their 
experiences.  The  children  should  be  stimulated  by  this  lesson  to  a keetv 
interest  in  the  nesting  habits  of  the  sunfishes. 

Observations — 1.  Where  are  the  sunfish  found?  How  do  they  act 
when  they  take  the  hook  ? 

2.  What  is  the  general  shape  of  the  sunfish’s  body  as  seen  from 
above?  As  seen  from  the  side?  Why  is  it  called  pumpkin  seed? 

3.  Describe  the  dorsal  fin.  How  many  spines  has  it?  How  many 
soft  rays?  What  is  the  difference  in  appearance  between  the  front  and 
hind  dorsal  fin?  Do  the  two  act  together  or  separately?  Describe  the 
tail  fin.  Describe  the  anal  fin.  Has  it  any  spines?  If  so,  where  are  they! 
Where  are  the  ventral  fins  in  relation  to  the  pectorals?  What  is  there 
peculiar  about  the  appearance  and  movements  of  the  pectoral  fins  ? 

4.  Describe  the  eye  of  the  sunfish.  Is  it  large  or  small?  Is  it 
placed  so  that  the  fish  can  see  on  each  side?  Does  the  eye  move  in  all 
directions  ? 

5.  Describe  the  position  of  the  mouth.  In  which  direction  does  it 
open?

“ The  lamprey  is  not  a fish  at  all,  only  a wicked  imitation  of  one  which  can  deceive 
nobody.  But  there  are  fishes  which  are  unquestionably  fish — fish  from  gills  to  tail,  from 
head  to  fin,  and  of  these  the  little  sunfish  may  stand  first.  He  comes  up  the  brook  in  the 
spring,  fresh  as  “ coin  just  from  the  mint,”  finny  arms  and  legs  wide  spread,  his  gills 
moving,  his  mouth  opening  and  shutting  rhythmically,  his  tail  wide  spread,  and  ready 
for  any  sudden  motion  for  which  his  erratic  little  brain  may  give  the  order.  The  scales 
of  the  sunfish  shine  with  all  sorts  of  scarlet,  blue,  green  and  pur  pie  and  golden  colors. 
There  is  a black  spot  on  his  head  which  looks  like  an  ear,  and  sometimes  grows  out  in  a 
long  black  flap,  which  makes  the  imitation  still  closer.  There  are  many  species  of  the 
sunfish,  and  there  may  be  half  a dozen  of  them  in  the  same  brook,  but  that  makes  no 
difference ; for  our  purposes  they  are  all  one. 

They,  lie  poised  in  the  water,  with  all  fins  spread,  strutting  like  turkey-cocks,  snap- 
ping at  worms  and  little  crustaceans  and  insects  whose  only  business  in  the  brook  is  that 
the  fishes  may  eat  them.  When  the  time  comes,  the  sunfish  makes  its  nest  in  the  fine 
gravel,  building  it  with  some  care — for  a fish.  When  the  female  has  laid  her  eggs  the 
male  stands  guard  until  the  eggs  are  hatched.  His  sharp  teeth  and  snappish  ways,  and 
the  bigness  of  his  appearance  when  the  fins  are  all  displayed,  keep  the  little  fishes  away. 
Sometimes,  in  his  zeal,  he  snaps  at  a hook  baited  with  a worm.  He  then  makes  a fierce 
fight,  and  the  boy  who  holds  the  rod  is  sure  that  he  has  a real  fish  this  time.  But  when 
the  sunfish  is  out  of  the  water,  strung  on  a willow  rod,  and  dried  in  the  sun,  the  boy  sees 
that  a very  little  fish  can  make  a good  deal  of  a fuss.”

The  johnny  darter  likes  a swift-flowing  brook 


THE  JOHNNY  DARTER 

Teacher's  Story 

“IVe  never  tired  of  watching  the  little  Johnny , or  Tessellated  darter  ( Boleosoma 
nigrum) , although  our  earliest  aquarium  friend,  {and  the  very  first  specimens  showed  us 
by  a rapid  ascent  of  the  river  weed  how  ‘a  Johnny  could  climb  trees,')  he  has  still  many 
resources  which  we  have  never  learned.  Whenever  we  try  to  catch  him  with  the  hand 
we  begin  with  all  the  uncertainty  that  characterized  our  first  attempts,  even  if  we  have 
him  in  a two-quart  pail.  We  may  know  him  by  his  short  fins,  his  first  dorsal  having 
but  nine  spines,  and  by  the  absence  of  all  color  save  a soft,  yellowish  brown,  which  is 
freckled  with  darker  markings.  The  dark  brown  on  the  sides  is  arranged  in  seven  or 
eight  W-shaped  marks,  below  which  are  a few  flecks  of  the  same  color.  Covering  the 
sides  of  the  back  are  the  wavy  markings  and  dark  specks  which  have  given  the  name  of 
the  “Tessellated  Darter but  Boleosoma  is  a preferred  name,  and  we  even  prefer  ‘boly‘ 
for  short.  In  the  spring  the  males  have  the  head  jet  black;  and  this  dark  color  often 
extends  on  the  back  part  of  the  body,  so  that  the  fish  looks  as  if  he  had  been  taken  by  tie* 
tail  and  dipped  into  a bottle  of  ink.  But  with  the  end  of  the  nuptial  season  this  colt* 
disappears  and  the  fish  regains  his  normal,  strawy  hue. 

His  actions  are  rather  bird-like ; for  he  will  strike  attitudes  like  a tufted  titmoua 
and  he  flies  rather  than  swims  through  the  water.  He  will,  with  much  perseverance 
push  his  body  between  a plant  and  the  sides  of  the  aquarium  and  balance  himself  on  <•- 
slender  stem.  Crouching  catlike  before  a snail  shell,  he  will  snap  off  a horn  which  thy  ■ 
unlucky  owner  pushes  timidly  out.  But  he  is  also  less  dainty  and  seizing  the  anim u* 
by  the  head,  he  dashes  the  shell  against  the  glass  or  stones  until  he  pulls  the  body  out  w 
breaks  the  shell." — -David  Starr  Jordan. 

The  johnny  darters  are,  with  the  sticklebacks,  the  most  amusing  little 
fish  in  the  aquarium.  They  are  well  called  darters  since  their  movements 
are  so  rapid  when  they  are  frightened  that  the  eye  can  scarcely  follow 
them;  and  there  is  something  so  irresistibly  comical  in  their  bright,  saucy

eyes,  placed  almost  on  top  of  the  head,  that  no  one  could  help  calling  one 
of  them  “Johnny.”  A “johnny”  will  look  at  you  from  one  side,  and  then 
as  quick  as  a flash,  will  flounce  around  and  study  you  with  the  other  eye 
and  then  come  toward  you  head-on  so  that  he  may  take  you  in  with  both 
eyes;  he  seems  just  as  interested  in  the  Johnny  out  of  the  jar  as  is  the 
latter,  in  the  johnny  within. 

The  johnny  darter  has  a queer  shaped  body  for  a fish,  for  the  head 
and  shoulders  are  the  larger  part  of  him;  not  that  he  suddenly  disappears 
into  nothingness,  by  no  means!  His  body  is  long  and  very  slightly 
tapering  to  the  tail;  along  his  lateral  line  he  has  a row  of  olive-brown  W’s 
worked  out  in  scale-mosaics;  and  he  has  some  other  scale-mosaics  also 
following  a pattern  of  angular  lines  and  making  blotches  along  his  back. 
The  whole  upper  part  of  his  body  is  pale  olive,  which  is  a good  imitation 


of  the  color  of  the  brook. 

The  astonished  and  anxious  look  on  the  johnny  darter’s  face  comes 
from  the  peculiar  position  of  the  eyes  which  are  set  in  the  top  of  his  fore- 
head; they  are  big,  alert  eyes,  with  large  black  pupils,  surrounded  by  a 
shining,  pale  yellow  line  at  the  inner  edge  of  the  green  iris;  and  as  the 
pupil  is  not  set  in  the  center  of  the  eye,  the  iris  above  being  wider  than 
below,  the  result  is  an  astonished  look,  as  from  raised  eyebrows.  The 
eyes  move,  often  so  swiftly  that  it  gives  the  impression  of  winking.  The 
eyes,  the  short  snout,  and  the  wide  mouth  give  johnny  a decidedly  frog- 
like aspect. 

Although  he  is  no 
frog,  yet  johnny  darter 
seems  to  be  in  a fair 
way  to  develop  some- 
thing to  walk  upon.  His 
pectoral  fins  are  large 
and  strong  and  the  ven- 
tral pair  are  situated 
very  close  to  them ; when 
he  rests  upon  the  gravel  he  supports  himself  upon  one  or  both  of  these 
pairs  of  fins.  He  rests  with  the  pectoral  fins  outspread,  the  sharp  points 
of  the  rays  taking  hold  of  the  gravel  like  toenails  and  thus  give  him  the 
appearance  of  walking  on  his  fins ; if  you  poke  him  gently,  you  will  find 
that  he  is  very  firmly  planted  on  his  fins  so  that  you  can  turn  him  around 
as  if  he  were  on  a pivot.  He  also  uses  the  pectorals  for  swimming  and 
jerks  himself  along  with  them  in  a way  that  makes  one  wonder  if  he  could 
not  swim  well  without  any  tail  at  all.  The  tail  is  large  and  almost  straight 
across  the  end  and  is  a most  vigorous  pusher.  There  are  two  dorsal  fins ; 
the  front  one  has  only  nine  rays ; these  are  not  branched  and  are  therefore 
spines;  when  the  fin  is  raised  it  appears  almost  semi-circular  in  shape. 
The  hind  dorsal  fin  is  much  longer  and  when  lifted  stands  higher  than 
the  front  one;  its  rays  are  all  branched  except  the  front  one.  As 
soon  as  the  johnny  stops  swimming  he  shuts  the  front  dorsal  fin  so  that 
it  can  scarcely  be  detected ; when  frightened  he  shuts  both  the  dorsal  fins 
and  closes  the  tail  and  the  anal  fin  and  spreads  out  his  paired  fins  so  that 
his  body  lies  flat  on  the  bottom;  this  act  always  reminds  one  of  the 
“freezing”  habit  of  the  rabbit.  But  johnny  does  not  stay  scared  very 
long;  he  lifts  his  head  up  inquisitively,  stretching  up  as  far  as  he  is  able 
on  his  front  feet,  that  is,  his  pectorals,  in  such  a comical  way  that  one 
can  hardly  realize  he  is  a fish.

The  tail  and  the  dorsal  fin  of  the  johnny  darter  are  marked  with  silver 
dots  which  give  them  an  exquisite  spun-glass  look ; they  are  as  transparent 
as  gauze. 

The  johnny  darters  live  in  clear,  swift  streams  where  they  rest  on  the 
bottom,  with  the  head  up  stream.  Dr.  Jordan  has  said  they  can  climb 
up  water  weed  with  their  paired  fins.  I have  never  observed  them  doing 
this  but  I have  often  seen  one  walk  around  the  aquarium  on  his  fins  as  if 
they  were  little  fan-shaped  feet ; and  when  swimming  he  uses  his  fins  as  a 
bird  uses  its  wings.  There  are  many  species  of  darters,  some  of  them  the 
most  brilliantly  colored  of  any  of  our  fresh-water  fishes.  The  darters  are 
perch-like  in  form. 

Dr.  Jordan  says  of  the  breeding  habits  of  the  darters:  “On  the  bot- 

tom, among  the  stones,  the  female  casts  her  spawn.  Neither  she  nor  the 
male  pays  any  further  attention  to  it,  but  in  the  breeding  season  the  male 
is  painted  in  colors  as  beautiful  as  those  of  the  wood  warblers.  When  you 
go  to  the  brook  in  the  spring  you  will  find  him  there,  and  if  you  catch  him 
and  tarn  him  over  on  his  side  you  will  see  the  colors  that  he'  shows  to  his 
mate,  and  which  observation  shows  are  most  useful  in  frightening  away 
his  younger  rivals.  But  do  not  hurt  him.  Put  him  back  in  the  brook 
and  let  him  paint  its  bottom  with  colors  of  a rainbow,  a sunset  or  a gar- 
den of  roses.  All  that  can  be  done  with  blue,  crimson  and  green  pig- 
ments, in  fish  ornamentation,  you  will  find  in  some  brook  in  which  the 
darters  live.” 


LESSON  XLIII 
Johnny  Darter 

Leading  thought — The  johnny  darter  naturally  rests  upon  the  bottom 
of  the  stream  where  the  current  is  swift.  It  uses  its  two  pairs  of  paired 
fins  somewhat  as  feet  in  a way  interesting  to  observe. 

Method — Johnny  darters  may  be  caught  in  nets  with  other  small  fry 
and  placed  in  the  aquarium.  Place  one  or  two  of  them  in  individual 
aquaria  where  the  pupils  may  observe  them  at  their  leisure.  They  do 
best  in  running  water. 

Observations — 1.  Describe  or  sketch  the  johnny  darter  from  above. 
From  the  side.  Can  you  see  the  W-shaped  marks  along  its  side?  How  is 
it  colored  above  ? 

2.  How  are  the  pectoral  fins  placed?  Are  they  large  or  small? 
How  are  they  used  in  swimming?  Where  are  the  ventral  fins  placed? 
How  are  the  ventrals  and  dorsals  used  together?  When  resting  on  the 
bottom  how  are  the  pectoral  fins  used? 

3.  What  is  there  peculiar  about  the  dorsal  fins  of  the  johnny 
darter?  When  he  is  resting,  what  is  the  attitude  of  the  dorsal  fins? 
What  is  the  difference  in  shape  of  the  rays  of  the  front  and  hind  dorsal 
fins? 

4.  When  resting  on  the  bottom  of  the  aquarium  how  is  the  body 
held?  On  what  does  it  rest?  In  moving  about  the  bottom  slowly  why 
does  it  seem  to  walk?  How  does  it  climb  up  water  weed? 

5.  When  frightened  how  does  it  act?  Why  is  it  called  a darter? 
What  is  the  attitude  of  all  the  fins  when  the  fish  is  moving  swiftly  ? 

6.  What  is  the  shape  of  the  tail?

Handbook  of  Nature-Study 


7.  What  is  there  peculiar  about  the  eyes  of  the  johnny?  Describe 
the  eyes  and  their  position.  What  reason  is  there  in  the  life  of  the  fish 
that  makes  this  position  of  the  eyes  advantageous? 

8.  Where  do  we  find  the  johnny  darters?  In  what  part  of  the 
stream  do  they  live  ? Are  they  usually  near  the  surface  of  the  water  or  at 
the  bottom? 


"To  my  mind,  the  best  of  all  subjects  for  nature-study  is  a brook.  It  affords  studies 
of  many  kinds.  It  is  near  and  dear  to  every  child.  It  is  an  epitome  of  the  nature  in 
which  we  live.  In  miniature,  it  illustrates  the  forces  which  have  shaped  much  of  the 
earth's  surface.  It  reflects  the  sky.  It  is  kissed  by  the  sun.  It  is  rippled  by  the  wind. 
The  minnows  play  in  the  pools.  The  soft  weeds  grow  in  the  shallows.  The  grass  and 
the  dandelions  lie  on  its  sunny  banks.  The  moss  and  the  fern  are  sheltered  in  the  nooks . 
It  comes  from  one  knows  not  whence;  it  flows  to  one  knows  not  whither.  It  awakens 
the  desire  to  explore.  It  is  fraught  with  mysteries.  It  typifies  the  flood  of  life.  It 
goes  on  forever. 

In  other  words,  the  reason  why  the  brook  is  such  a perfect  nature-study  subject  is  the 
fact  that  it  is  the  central  theme  in  a scene  of  life.  Living  things  appeal  to  children ." 

“ Nature-study  not  only  educates,  but  it  educates  nature-ward ; and  nature  is  ever  our 
companion,  whether  we  will  or  no.  Even  though  we  are  determined  to  shut  ourselves  in 
an  office,  nature  sends  her  messengers.  The  light,  the  dark,  the  moon,  the  cloud,  the 
rain,  the  wind,  the  falling  leaf,  the  fly,  the  bouquet,  the  bird,  the  cockroach — they  are  all 
ours. 

If  one  is  to  be  happy  , he  must  be  in  sympathy  with  common  things.  He  must  live  in 
harmony  with  his  environment.  One  cannot  be  happy  yonder  nor  tomorrow:  he  is 
happy  here  and  now,  or  never.  Our  stock  of  knowledge  of  common  things  should  be 
great.  Few  of  us  can  travel.  We  must  know  the  things  at  home. 

Nature-love  tends  toward  naturalness,  and  toward  simplicity  of  living.  It  tends 
country-ward.  One  word  from  the  fields  is  worth  two  from  the  city.  “ God  made  the 
country." 

I expect,  therefore,  that  much  good  will  come  from  nature-study.  It  ought  to 
revolutionize  the  school  life,  for  it  is  capable  of  putting  new  force  and  enthusiasm  into 
the  school  and  the  child.  It  is  new,  and  therefore,  is  called  a fad.  A movement  is  a fad 
until  it  succeeds.  We  shall  learn  much,  and  shall  outgrow  some  of  our  present  notions , 
but  nature-study  has  come  to  stay.  It  is  in  much  the  same  stage  of  development  theft 
manual-training  and  kindergarten  work  were  twenty-five  years  ago.  We  must  take  care 
that  it  does  not  crystalize  into  science-teaching  on  the  one  hand,  nor  fall  into  mere 
sentimentalism  on  the  other. 

I would  again  emphasize  the  importance  of  obtaining  our  fact  before  we  let  loose  the 
imagination,  for  on  this  point  will  largely  turn  the  results — the  failure  or  the  success  of 
the  experiment.  We  must  not  allow  our  fancy  to  run  away  with  us.  If  we  hitch  our 
wagon  to  a star,  we  must  ride  with  mind  and  soul  and  body  all  alert.  When  we  ride  in 
such  a wagon,  we  must  not  forget  to  put  in  the  tail-board.”

III.  BATRACHIAN  STUDY 


THE  COMMON  TOAD 
Teacher's  Story 

“ The  toad  hopped  by  us  with  jolting  springs .” — Akers. 

HOEVER  has  not  had  a pet  toad  has  missed  a most 
entertaining  experience.  Toad  actions  are  surpris- 
ingly interesting;  one  of  my  safeguards  against  the 
blues  is  the  memory  of  the  thoughtful  way  one  of  my 
pet  toads  rubbed  and  patted  its  stomach  with  its  little 
hands  after  it  had  swallowed  a June-bug.  Toads  do 
not  make  warts  upon  attacking  hands,  neither  do  they 
rain  down  nor  are  they  found  in  the  bed-rock  of 
quarries;  but  they  do  have  a most  interesting  history  of  their  own, 
which  is  not  at  all  legendary,  and  which  is  very  like  a life  with  two  in- 
carnations. 

The  mother  toad  lays  her  eggs  in  May  and  June  in  ponds,  or  in  the  still 
pools,  along  streams;  the  eggs  are  laid  in  long  strings  of  jellylike  sub- 
stance, and  are  dropped  upon  the  pond  bottom  or  attached  to  water 
weeds;  when  first  deposited,  the  jelly  is  transparent  and  the  little  black 
eggs  can  be  plainly  seen;  but  after  a day  or  two,  bits  of  dirt  accumulate 
upon  the  jelly,  obscuring  the  eggs.  At  first  the  eggs  are  spherical,  like 
tiny  black  pills,  but  as  they  begin  to  develop,  they  elongate  and  finally 
the  tadpoles  may  be  seen  wriggling  in  the  jelly  mass,  which  affords  them 
efficient  protection.  After  four  or  five  days,  the  tadpoles  usually 
work  their  way  out  and  swim  away;  at  this  stage,  the  only  way  to  detect 
the  head,  is  by  the  direction  of  the  tadpole’s  progress,  since  it  naturally 
goes  head  first.  However,  the  head  soon  becomes  decidedly  larger, 
although  at  first  it  is  not  provided  with  a mouth;  it  has  instead,  a 
V-shaped  elevation  where  the  mouth  should  be,  which  forms  a sucker 
secreting  a sticky  substance  by  means  of  which  the  tadpole  attaches 
itself  to  water  weeds,  resting  head  up.  When  two  or  three  days  old,  we 
can  detect  little  tassels  on  either  side  of  the  throat,  which  are  the  gills 
by  which  the  little  creature  breathes;  the  blood  passes  through  these 
gills,  and  is  purified  by  coming  in  contact  with  the  air  which  is  mixed  in 
the  water.  About  ten  days  later,  these  gills  disappear  beneath  a mem- 
brane which  grows  down  over  them;  but  they  are  still  used  for  breathing, 
simply  having  changed  position  from  the  outside  to  the  inside  of  the 
throat.  The  water  enters  the  nostrils  to  the  mouth,  passes  through  an 
opening  in  the  throat  and  flows  over  the  gills  and  out  through  a little 
opening  at  the  left  side  of  the  body;  this  opening  or  breathing-pore,  can 
be  easily  seen  in  the  larger  tadpoles;  and  when  the  left  arm  develops,  it  is 
pushed  out  through  this  convenient  orifice. 

When  about  ten  days  old,  the  tadpole  has  developed  a small,  round 
mouth  which  is  constantly  in  search  of  something  to  eat,  and  at  the  same 
time  constantly  opening  and  shutting  to  take  in  air  for  the  gills;  the 
mouth  is  provided  with  horny  jaws  for  biting  off  pieces  of  plants.  As  the 


182 


Handbook  of  Nature-Study 


tadpole  develops,  its  mouth  gets  larger  and  wider  and  extends  back 
beneath  the  eyes,  with  a truly  toadlike  expansiveness. 

At  first,  the  tadpole’s  eyes  are  even  with  the  surface  of  the  head  and 
can  scarcely  be  seen,  but  later  they  become  more  prominent  and  bulge 
like  the  eyes  of  the  adult  toad. 

The  tail  of  the  tadpole  is  long  and  flat,  surrounded  by  a fin,  thus 
making  an  organ  for  swimming.  It  strikes  the  water,  first  this  side  and 
then  that,  making  most  graceful  curves,  which  seem  to  originate  near  the 


Toad's  eggs.

body  and  multiply  toward  the  tip  of  the  tail.  This  movement  propels 
the  tadpole  forward,  or  in  any  direction.  The  tail  is  very  thin  when  seen 
from  above;  and  it  is  amusing  to  look  at  a tadpole  from  above,  and  then 
at  the  side;  it  is  like  squaring  a circle. 

There  is  a superstition  that  tadpoles  eat  their  tails;  and  in  a sense  this 
is  true,  because  the  material  that  is  in  the  tail  is  absorbed  into  the  growing 
body;  but  the  last  thing  a right-minded  tadpole  would  do,  would  be  to 
bite  off  its  own  tail.  However,  if  some  other  tadpole  should  bite  off  the 
tail  or  a growing  leg,  these  organs  conveniently  grow  anew. 

When  the  tadpole  is  a month  or  two  old,  depending  upon  the  species, 
its  hind  legs  begin  to  show;  they  first  appear  as  mere  buds  which  finally 
push  out  completely.  The  feet  are  long  and  provided  with  five  toes,  of 
which  the  fourth  is  the  longest ; the  toes  are  webbed  so  that  they  may  be 
used  to  help  in  swimming.  Two  weeks  later  the  arms  begin  to  appear, 
the  left  one  pushing  out  through  the  breathing-pore.  The  “hands”  have 
four  fingers  and  are  not  webbed;  they  are  used  in  the  water  for  balancing; 
while  the  hind  legs  are  used  for  pushing,  as  the  tail  becomes  smaller. 


Batrachian  Study 


183 

As  the  tadpole  grows  older,  not  only  does  its  tail  become  shorter  but 
its  actions  change.  It  now  comes  often  to  the  surface  of  the  water  in 
order  to  get  more  air  for  its  gills,  although  it  lacks  the  frog  tadpole’s 
nice  adjustment  of  the  growing  lungs  and  the  disappearing  gills.  At 
last  some  fine  rainy  day,  the  little  creature  feels  that  it  is  finally  fitted 
to  live  the  life  of  a land  animal.  It  may  not  be  a half  inch  in 
length,  with  big  head,  attenuated  body  and  stumpy  tail,  but  it  swims  to 
the  shore,  lifts  itself  on  its  front  legs,  which  are  scarcely  larger  than  pins, 
and  walks  off,  toeing  in,  with  a very  grown  up  air,  and  at  this  moment,  the 
tadpole  attains  toadship.  Numbers  of  them  come  out  of  the  water 
together,  hopping  hither  and  thither  with  all  of  the  eagerness  and  vim  of 
untried  youth.  It  is  when  issuing  thus  in  hordes  from  the  water  and  seen 
by  the  ignorant,  that  they  gain  the  reputation  of  being  rained  down,  when 
they  really  were  rained  up.  It  is  quite  impossible  for  a beginner  to  detect 
the  difference  between  the  toad  and  the  frog  tadpole ; usually  those  of  the 
toads  are  black,  while  those  of  the  frogs  are  otherwise  colored,  though  this 
is  not  an  invariable  distinction.  The  best  way  to  distinguish  the  two  is 
to  get  the  eggs  and  develop  the  two  families  separately. 

The  general  color  of  the  common  American  toad  is  extremely  variable. 
It  may  be  yellowish-brown,  with* spots  of  lighter  color,  and  with  reddish  or 
yellow  warts.  There  are  likely  to  be  four  irregular  spots  of  dark  color 
along  each  side  of  the  middle  of  the  back,  and  the  under  parts  are  light 
colored,  often  somewhat  spotted.  The  throat  of  the  male  toad  is  black 
and  he  is  not  so  bright  m color  as  is  the  female.  The  warts  upon  the  back 
are  glands,  which  secrete  a substance  disagreeable  for  the  animal  seeking 
toad  dinners.  This  is  especially  true  of  the  glands  in  the  elongated 
swelling  or  wart,  above  and  just  back  of  the  ear,  which  is  Called  the 
parotid  gland;  these  give  forth  a milky,  poisonous  substance  when  the 
toad  is  seized  by  an  enemy,  although  the  snakes  do  not  seem  to  mind  it. 
Some  people  have  an  idea  that  the  toad  is  slimy,  but  this  is  not  true;  the 
skin  is  perfectly  dry.  The  toad  feels  cold  to  the  hand  because  it  is  a cold- 
blooded animal,  which  means  an  animal  with  blood  the  temperature  of 
the  surrounding  atmosphere;  while  the  blood  of  the  warm-blooded 
animal,  has  a temperature  of  its  own,  which  it  maintains  whether  the 
surrounding  air  is  cold  or  hot. 

The  toad’s  face  is  well  worth 
study;  its  eyes  are  elevated 
and  very  pretty,  the  pupil  being 
oval  and  the  surrounding  iris 
shining  like  gold.  The  toad 
winks  in  a wholesale  fashion,  the 
eyes  being  pulled  down  into  the 
head ; the  eyes  are  provided  with 
nictitating  lids,  which  rise  from 
below,  and  are  similar  to  those 
found  in  birds.  When  a toad  is 
sleeping,  its  eyes  do  not  bulge 
but  are  drawn  in,  so  as  to  lie  even 
with  the  surface  of  the  head. 

The  two  tiny  nostrils  are  black 
and  are  easily  seen ; the  ear  is  a 
flat,  oval  spot  behind  the  eye

and  a little  lower  down ; in  the  common  species  it  is  not  quite  so  large 
as  the  eye;  this  is  really  the  ear-drum,  since  there  is  no  external  ear  like 
ours.  The  toad’s  mouth  is  wide  and  its  jaws  are  homy;  it  does  not  need 
teeth  since  it  swallows  its  prey  whole. 

The  toad  is  a jumper,  as  may  be  seen  from  its  long,  strong  hind  legs, 
the  feet  of  which  are  also  long  and  strong  and  armed  with  five  toes 
that  are  somewhat  webbed.  The  “arms”  are  shorter  and  there  are 
four  “fingers”  to  each  “hand;”  when  the  toad  is  resting,  its  front 
feet  toe-in,  in  a comical  fashion.  If  a toad  is  removed  from  an 
earth  or  moss  garden,  and  put  into  a white  wash-bowl,  in  a few  hours  it 
will  change  to  a lighter  hue,  and  vice  versa.  This  is  part  of  its  pro- 
tective color,  making  it  inconspicuous  to  the  eyes  of  its  enemy.  It 
prefers  to  live  in  cool,  damp  places,  beneath  sidewalks  or  piazzas,  etc., 
and  its  warty  upper  surface  resembles  the  surrounding  earth.  If  it  is 
disturbed,  it  will  seek  to  escape  by  long  leaps  and  acts  frightened;  but 
if  very  much  frightened,  it  flattens  out  on  the  ground,  and  looks  so 
nearly  like  a clod  of  earth  that  it  may  escape  even  the  keen  eyes  of  its 
pursuer.  When  seized  by  the  enemy,  it  will  sometimes  “play  possum,” 
acting  as  if  it  were  dead ; but  when  actually  in  the  mouth  of  the  foe,  it 
emits  terrified  and  heart-rending  cries. 

The  toad’s  tongue  is  attached  to  the  lower  jaw,  at  the  front  edge  of  the 
mouth;  it  can  thus  be  thrust  far  out,  and  since  it  secretes  a sticky  sub- 
stance over  its  surface,  any  insects  which  it  touches  adhere,  and  are  drawn 
back  into  the  mouth  and  swallowed.  It  takes  a quick  eye  to  see  this 
tongue  fly  out  and  make  its  catch.  The  tadpole  feeds  mostly  upon 
vegetable  matter,  but  the  toad  lives  entirely  upon  small  animals,  usually 
insects;  it  is  not  particular  as  to  what  kind  of  insects;  but  because  of  the 
situations  which  it  haunts,  it  usually  feeds  upon  those  which  are  injurious 
to  grass  and  plants.  Indeed,  the  toad  is  really  the  friend  of  the  gardener 
and  farmer,  and  has  been  most  ungratefully  treated  by  those  whom  it 
has  befriended.  If  you  doubt  that  a toad  is  an  animal  of  judgment, 
watch  it  when  it  finds  an  earthworm  and  set  your  doubts  at  rest ! It  will 
walk  around  the  squirming  worm,  until  it  can  seize  it  by  the  head, 
apparently  knowing  well  that  the  horny  hooks  extending  backward  from 
the  segments  of  the  worm,  are  likely  to  rasp  the  throat  if  swallowed  the 
wrong  way.  If  the  worm  prove  a too  large  mouthful,  the  toad  promptly 
uses  its  hands  in  an  amusing  fashion  to  stuff  the  wriggling  morsel  down 
its  throat.  When  swallowing  a large  mouthful,  it  closes  its  eyes;  but 
whether  this  aids  the  process,  or  is  merely  an  expression  of  bliss,  we  have 
not  determined.  The  toad  never  drinks  by  taking  in  water  through  the 
mouth,  but  absorbs  it  through  the  skin;  when  it  wishes  to  drink,  it 
stretches  itself  out  in  shallow  water  and  thus  satisfies  its  thirst;  it  will 
waste  away  and  die  in  a short  time,  if  kept  in  a dry  atmosphere. 

The  toad  burrows  in  the  earth  by  a method  of  its  own,  hard  to  describe. 
It  kicks  backward  with  its  strong  hind  legs,  and  in  some  mysterious  way, 
the  earth  soon  covers  all  excepting  its  head;  then,  if  an  enemy  comes 
along,  back  goes  the  head,  the  earth  caves  in  around  it,  and  where  is  your 
toad ! It  remains  in  its  burrow  or  hiding  place  usually  during  the  day, 
and  comes  out  at  night  to  feed.  This  habit  is  an  advantage,  because 
snakes  are  then  safely  at  home  and,  too,  there  are  many  more  insects  to 
be  found  at  night.  The  sagacious  toads  have  discovered  that  the 
vicinity  of  street  lights  is  swarming  with  insects,  and  there  they  gather  in

numbers.  In  winter  they  burrow  deeply  in  the  ground  and  go  to  sleep, 
remaining  dormant  until  the  warmth  of  spring  awakens  them;  then,  they 
come  out,  and  the  mother  toads  seek  their  native  ponds  there  to  lay  eggs 
for  the  coming  generation.  They  are  excellent  swimmers;  when  swim- 
ming rapidly,  the  front  legs  are  laid  backward  along  the  sides  of  the  body, 
so  as  to  offer  no  resistance  to  the  water;  but  when  moving  slowly,  the 
front  legs  are  used  for  balancing  and  for  keeping  afloat. 

The  song  of  the  toad  is  a pleasant,  crooning  sound,  a sort  of  gutteral 
trill;  it  is  made  when  the  throat  is  puffed  out  almost  globular,  thus  form- 
ing a vocal  sac ; the  sound  is  made  by  the  air  drawn  in  at  the  nostrils  and 
passed  back  and  forth  from  the  lungs  to  the  mouth  over  the  vocal  chords, 
the  puffed-out  throat  acting  as  a resonator. 

The  toad  has  no  ribs  by  which  to  inflate  the  chest,  and  thus  draw  air 
into  the  lungs,  as  we  do  when  we  breathe;  it  is  obliged  to  swallow  the  air 
instead  and  thus  force  it  into  the  lungs.  This  movement  is  shown  in  the 
constant  pulsation,  in  and  out,  of  the  membrane  of  the  throat. 

As  the  toad  grows,  it  sheds  its  homy  skin,  which  it  swallows;  as  this 
process  is  usually  done  strictly  in  private,  the  ordinary  observer  sees  it 
but  seldom.  One  of  the  toad’s  nice  common  qualities  is  its  enjoyment  in 
having  its  back  scratched  gently. 

The  toad  has  many  enemies;  chief  among  these  is  the  snake  and  in 
only  a lesser  degree,  crows  and  also  birds  of  prey.

LESSON  XLIV 
The  Tadpole  Aquarium 

Leading  thought — The  children 
should  understand  how  to  make 
the  tadpoles  comfortable  and 
thus  be  able  to  rear  them. 

Materials — A tin  or  agate  pan 
or  a deep  earthenware  wash- 
bowl. 

Things  to  he  done — 1.  Go  to 
some  pond  where  tadpoles  live. 

2.  Take  some  of  the  small 
stones  on  the  bottom  and  at  the 
sides  of  the  pond  lifting  them 
very  gently  so  as  not  to  disturb 
what  is  growing  on  their  surface. 

Place  these  stones  on  the  bottom 
of  the  pan,  building  up  one  side 
higher  than  the  other,  so  that 
the  water  will  be  more  shallow 
on  one  side  than  on  the  other; 
a stone  or  two  should  project 
above  the  water. 

3.  Take  some  of  the  mud  and  leaves  from  the  bottom  of  the  pond, 
being  careful  not  to  disturb  them  and  place  upon  the  stones. 


i86 


Handbook  of  Nature-Study 


4.  Take  some  of  the  plants  found  growing  under  water  in  the  pond 
and  plant  them  among  the  stones. 

5.  Carry  the  pan  thus  prepared  back  to  the  schoolhouse  and  place  it 
where  the  sun  will  not  shine  directly  upon  it. 

6.  Bring  a pail  of  water  from  the  pond  and  pour  it  very  gently  in  at 
one  side  of  the  pan,  so  as  not  to  disarrange  the  plants ; fill  the  pan  nearly 
to  the  brim. 

7.  After  the  mud  has  settled  and  the  water  is  perfectly  clear,  remove 
some  of  the  tadpoles,  which  have  hatched  in  the  glass  aquarium,  and  place 
in  the  “pond.”  Not  more  than  a dozen  should  be  put  in  a pan  of  this 
size,  since  the  amount  of  food  and  microscopic  plants  which  are  on  the 
stones  in  the  mud,  will  afford  food  for  only  a few  tadpoles. 

8.  Every  week  add  a little  more  mud  from  the  bottom  of  the  pond  or 
another  stone  covered  with  slime,  which  is  probably  some  plant  growth. 
More  water  from  the  pond  should  be  added  to  replace  that  evaporated. 

9.  Care  should  be  taken  that  the  tadpole  aquarium  be  kept  where  the 
sun  will  not  shine  directly  upon  it  for  any  length  of  time,  because  if  the 
water  gets  too  warm  the  tadpoles  will  die. 

10.  Remove  the  “skin”  from  one  side  of  a tulip  leaf,  so  as  to  expose 
the  pulp  of  the  leaf,  and  give  to  the  tadpoles  every  day  or  two.  Bits  of 
hard-boiled  egg  should  be  given  now  and  then. 

Toads’  Eggs  and  Tadpoles 

Leading  thought — The  toad’s  eggs  are  laid  in  strings  of  jelly  in  ponds. 
The  eggs  hatch  into  tadpoles  which  are  creatures  of  the  water,  breathing 
by  gills,  and  swimming  with  a long  fin.  The  tadpoles  gradually  change  to 
toads,  which  are  air-breathing  creatures,  fitted  for  life  on  dry  land. 

Method — The  eggs  of  toads  may  be  found  in  almost  any  pond  about  the 
first  of  May  and  may  be  scraped  up  from  the  bottom  in  a scoop-net.  They 
should  be  placed  in  the  aquarium  where  the  children  can  watch  the  stages 
of  development.  Soon  after  they  are  hatched,  a dozen  or  so  should  be 
selected  and  placed  in  the  tadpole  aquarium  and  the  others  put  back  into 
the  stream.  The  children  should  observe  the  tadpoles  every  day,  watch- 
ing carefully  all  the  changes  of  structure  and  habit  which  take  place.  If 
properly  fed,  the  tadpoles  will  be  ready  to  leave  the  water  in  July,  as  tiny 
toads. 

Observations — 1.  Where  were  the  toads’  eggs  found  and  on  what 
date  ? Were  they  attached  to  anything  in  the  water  or  were  they  floating 
free?  Are  the  eggs  in  long  strings?  Do  you  find  any  eggs  laid  in  jelly- 
like  masses?  If  so,  what  are  they?  How  can  you  tell  the  eggs  of  toads 
from  those  of  frogs? 

2.  Is  the  jellylike  substance  in  which  the  eggs  are  placed  clear  or 
discolored?  What  is  the  shape  and  the  size  of  the  eggs?  A little  later 
how  do  they  look?  Do  the  young  tadpoles  move  about  while  they  are 
still  in  the  jelly  mass? 

3.  Describe  how  the  little  tadpole  works  its  way  out  from  the  jelly 
covering.  Can  you  distinguish  then  which  is  head  and  which  is  tail? 
How  does  it  act  at  first?  Where  and  how  does  it  rest? 

4.  Can  you  see  with  the  aid  of  a lens  the  little  fringes  on  each  side  of 
the  neck?  What  are  these?  Do  these  fringes  disappear  a little  later? 
Do  they  disappear  on  both  sides  of  the  neck  at  once  ? What  becomes  of

them?  How  does  the  tadpole  breathe?  Can  you  see  the  little  hole  on 
the  left  side,  through  which  the  water  used  for  breathing  passes  ? 

5.  How  does  the  tail  look  and  how  is  it  used?  How  long  is  it  in 
proportion  to  the  body?  Describe  the  act  of  swimming. 

6.  Which  pair  of  legs  appears  first  ? How  do  they  look?  When  they 
get  a little  larger  are  they  used  as  a help  in  swimming  ? Describe  the  hind 
legs  and  feet. 

7 . How  long  after  the  hind  legs  appear  before  the  front  legs  or  arms 
appear  ? What  happens  to  the  breathing-pore  when  the  left  arm  is  pushed 
through? 

8.  After  both  pairs  of  legs  are  developed  what  happens  to  the  tail? 
What  becomes  of  .it? 

9.  When  the  tadpole  is  very  young  can  you  see  its  eyes?  How  do 
they  look  as  it  grows  older?  Do  they  ever  bulge  out  like  toads’  eyes? 

10.  As  the  tadpole  gains  its  legs  and  loses  its  tail  how  does  it  change 
in  its  actions?  How  does  it  swim  now?  Does  it  come  oftener  to  the 
surface  ? Why  ? 

11.  Describe  the  difference  between  the  front  and  the  hind  legs  and 
the  front  and  the  hind  feet  on  the  fully  grown  tadpole.  If  the  tail  or 
a leg  is  bitten  off  by  some  other  creature  will  it  grow  again? 


LESSON  XLV 
The  Toad 

Leading  thought — The  toad  is  colored  so  that  it  resembles  the  soil  and 
thus  escapes  the  observation  of  its  enemies.  It  lives  in  damp  places  and 
eats  insects,  usually  hunting  them  at  night.  It  has  powerful  hind  legs 
and  is  a vigorous  jumper. 

Method — Make  a moss  garden  in  a glass  aquarium  jar  thus:  Place 

some  stones  or  gravel  in  the  bottom  of  the  jar  and  cover  with  moss. 
Cover  the  jar  with  a wire  screen.  The  moss  should  be  deluged  with 
water  at  least  once  a day  and  the  jar  should  be  placed  where  the  direct 
sunlight  will  not  reach  it.  In  this  jar,  place  the  toad  for  study. 

Observations — 1.  Describe  the  general  color  of  the  toad  above  and 
below.  How  does  the  toad’s  back  look?  Of  what  use  are  the  warts  on 
its  back? 

2 . Where  is  the  toad  usually  found  ? Does  it  feel  warm  or  cold  to  the 
hand?  Is  it  slimy  or  dry?  The  toad  is  a cold-blooded  animal,  what  does 
this  mean  ? 

3.  Describe  the  eyes  and  explain  how  their  situation  is  of  special 
advantage  to  the  toad.  Do  you  think  it  can  see  in  front  and  behind  and 
above  all  at  the  same  time.  Does  the  bulge  of  the  eyes  help  in  this? 
Note  the  shape  and  color  of  the  pupil  and  iris.  How  does  the  toad  wink? 

4.  Find  and  describe  the  nostrils.  Find  and  describe  the  ear. 
Note  the  swelling  above  and  just  back  of  the  ear.  Do  you  know  the  use 
of  this? 

5.  What  is  the  shape  of  the  toad’s  mouth?  Has  it  any  teeth?  Is 
the  toad’s  tongue  attached  to  the  front  or  the  back  part  of  the  mouth? 
How  is  it  used  to  catch  insects? 

6.  Describe  the  “arms  and  hands.”  How  many  “fingers”  on  the 
“hand?”  Which  way  do  the  fingers  point  when  the  toad  is  sitting  down? 


Batrachian  Study 


189 

7.  Describe  the  legs  and  feet.  How  many  toes  are  there?  What  is 
the  relative  length  of  the  toes  and  how  are  they  connected  ? What  is  this 
web  between  the  toes  for?  Why  are  the  hind  legs  so  much  larger  than 
the  front  legs  ? 

8.  Will  a toad  change  color  if  placed  upon  different  colored  objects? 
How  long  does  it  take  it  to  do  this  ? Of  what  advantage  is  this  to  the 
toad? 

9.  Where  does  the  toad  live  ? When  it  is  disturbed  how  does  it  act  ? 
How  far  can  it  jump  ? If  very  frightened  does  it  flatten  out  and  lie  still  ? 
Why  is  this? 

10.  At  what  time  does  the  toad  come  out  to  hunt  insects ? How  does 
it  catch  the  insect?  Does  it  swallow  an  earthworm  head  or  tail  first? 
When  swallowing  an  earthworm  or  large  insect,  how  does  it  use  its 
hands?  How  does  it  act  when  swallowing  a large  mouthful? 

1 1 . How  does  the  toad  drink  ? Wh  ere  does  it  remain  during  the  day  ? 
Describe  how  it  burrows  into  the  earth. 

12.  What  happens  to  the  toad  in  the  winter?  What  does  it  do  in 
the  spring?  Is  it  a good  swimmer?  How  does  it  use  its  legs  in  swimming? 

13.  How  does  the  toad  look  when  croaking?  What  sort  of  a noise 
does  it  make? 

14.  Describe  the  action  of  the  toad’s  throat  when  breathing.  Did 
you  ever  see  a toad  shed  its  skin  ? 

15.  What  are  the  toad’s  enemies?  How  does  it  act  when  caught  by 
a snake?  Does  it  make  any  noise?  Is  it  swallowed  head  or  tail  first? 
What  means  has  it  of  escaping  or  defending  itself  from  its  enemies  ? 

16.  How  is  the  toad  of  great  use  to  the  farmer  and  gardener?

SSOCIATED  with  the  first  songs  of  robin  and  bluebird, 
is  the  equally  delightful  chorus  of  the  spring  peepers, 
yet  how  infrequently  do  most  of  us  see  a member  of 
this  invisible  choir!  There  are  some  creatures  which 
are  the  quintessence  of  the  slang  word  “cute”  which, 
interpreted,  means  the  pefection  of  Lilliputian  pro- 
portions, permeated  with  undaunted  spirit.  The 
chickadee  is  one  of  these,  and  the  tree-frog  is  another. 
I confess  to  a thrill  of  delight  when  the  Picker- 
ing’s hyla  lifts  itself  on  its  tiny  front  feet,  twists 
its  head  knowingly,  and  turns  on  me  the  full 
gaze  of  its  bronze-rimmed  eyes.  This  is  the 
tiniest  froglet  of  them  all,  being  little  more  than 
an  inch  long  when  fully  grown;  it  wears  the 
Greek  cross  in  darker  color  upon  its  back,  with 
some  stripes  across  its  long  hind  legs  which  join 
the  pattern  on  the  back  when  the  frog  is  “shut 
up,”  as  the  boys  say. 

The  reason  we  see  so  little  of  tree-frogs,  is 
because  they  are  protected  from  discovery  by 
their  color.  They  have  the  chameleon  power 
of  changing  color  to  match  their  background. 

The  Pickering’s  hyla  will  effect  this  change  in 
twenty  minutes;  in  this  species,  the  darker 
lines  forming  the  cross  change  first,  giving  a 
mottled  appearance  which  is  at  once  protective. 

I have  taken  three  of  these  peepers,  all  of  them 
pale  yellowish  brown  with  gray  markings,  and 
have  placed  one  upon  a fern,  one  on  dark  soil 
and  one  on  the  purple  bud  of  a flower.  Within 
half  an  hour,  each  matched  its  surroundings  so 
closely,  that  the  casual  eye  would  not  detect 
them.  The  song  of  the  Pickering’s  hyla  is  a 
resonant  chirp,  very  stirring  when  heard  nearby; 
it  sounds  somewhat  like  the  note  of  a water  bird. 

How  such  a small  creature  can  make  such  a loud 
noise,  is  a mystery.  The  process,  however,  may 
be  watched  at  night  by  the  light  of  a lamp,  as 
none  of  the  tree-frogs  seem  to  pay  any  atten- 
tion to  an  artificial  light;  the  thin'  membrane 
beneath  the  throat  swells  out  until  it  seems 
almost  large  enough  to  balloon  the  little  chap  off 
his  perch  No  wonder  that,  with  such  a sound-  SM  for  ^ 
mg-sac,  the  note  is  stirring.  There  are  several  Pickering's  Hyla.

THE  TREE-FROG,  OR  TREE-TOAD 


Teacher's  Story 


“ Ere  yet  the  earliest  warbler  wakes,  of  coming  spring  to  tell% 

From  every  marsh  a chorus  breaks,  a choir  invisible, 

As  if  the  blossoms  underground,  a breath  of  utterance  had  found.” — Tabs.

above  our  heads  all  summer,  and  their  songs  are  sometimes  mistaken  for 
those  of  the  cicada,  which  is  far  more  shrill. 

The  tree-frogs  have  toes  and  fingers  ending  in  little  round  discs  which 
secrete  at  will  a substance  by  means  of  which  they  can  cling  to  vertical 
surfaces,  even  to  glass.  In  fact,  the  way  to  study  these  wonderful  feet  is 
when  the  frog  is  climbing  up  the  sides  of  the  glass  jar.  The  fingers  are 
arranged,  two  short  inside  ones,  a long  one,  and  another  short  one  outside. 
The  hind  feet  have  three  shorter  inside  toes  quite  far  apart,  a 
long  one  at  the  tip  of  the  foot  and  a shorter  one  outside.  When  climbing 
a smooth  surface  like  glass,  the  toes  are  spread  wide  apart,  and  there 
are  other  little  clinging  discs  on  their  lower  sides,  although  not  so 
large  as  those  at  the  tips.  It  is  by  means  of  these  sticky,  disc-like  toes 
that  the  tree-frogs  hold  themselves  upon  the  tree  trunks. 

The  whole  body  of  the  tree-frog  is  covered  with  little  tubercles, 
which  give  it  a roughened  appearance.  The  eyes  are  black  with  the  iris 
of  reddish  color.  The  tongue  is  like  that  of  other  frogs,  hinged  to  the 
front  of  the  lower  jaw;  it  is  sticky  and  can  be  thrust  far  out  to  capture 
insects,  of  which  the  tree-frcgs  eat  vast  numbers. 

The  hylas  breathe  by  the  rapid  pulsation  of  the  membrane  of 
the  throat,  which  makes  the  whole  body  tremble.  The  nostrils  are 
two  tiny  holes  on  either  side  of  the  tip  of  the  snout.  The  ears  are  a 
little  below  and  just  behind  the  eyes,  and  are  in  the  form  of  a circular 
slit. 


The  eggs  of  the  spring  peepers  are  laid  in  ponds  during  April;  each 
egg  has  a little  globe  of  jelly  about  it  and  is  fastened  to  a stone 
or  a water  plant.  The  tadpoles  are  small  and  delicate;  the  under  side 
of  the  body  is  reddish  and  shines  with  metallic  lustre.  These  tad- 
poles differ  from  those  of  other  frogs  in  that  they  often 
leave  the  water  while  yet 
the  tail  is  still  quite  long. 

In  summer,  they  may  be 
found  among  the  leaves  and 
moss  around  the  banks 
of  ponds.  They  are  in- 
defatigable in  hunting  for 
gnats,  mosquitoes  and  ants; 
their  destruction  of  mosqui- 
toes, as  pollywogs  and  as 
grown  up  frogs,  renders  them 
of  great  use  to  us.  The  voice 
of  this  peeper  may  be  heard 
among  the  shrubs  and  vines 
or  in  trees  during  late  sum- 
mer and  until  November. 

The  little  creatures  sleep  be- 
neath moss  and  leaves 
during  the  winter,  waking  to 
give  us  the  earliest  news  of 
spring.

The  Tree-frog  or  Tree-toad 

Leading  thought — The  prettiest  part  of  the  spring  chorus  of  the  frog 
ponds  is  sung  by  the  tree-frogs.  These  little  frogs  have  the  tips  of 
their  toes  specially  fitted  for  climbing  up  the  sides  of  trees. 

Method — Make  a moss  garden  in  an  aquarium  jar  or  a two-quart  can. 
Place  stones  in  the  bottom  and  moss  at  one  side,  leaving  a place  on 
the  other  side  for  a tiny  pond  of  water.  In  this  garden  place  a tree- 
frog  and  cover  the  jar  with  mosquito  netting  and  place  in  the  shade. 
The  frogs  may  be  found  by  searching  the  banks  of  a pond  at  night 
with  a lantern.  However,  this  lesson  is  usually  given  when  by 
accident  the  tree-frog  is  discovered.  Any  species  of  tree-frog  will  do ; but 
the  Pickering’s  hyla,  known  everywhere  as  the  spring  peeper,  is  the  most 
interesting  species  to  study. 

Observations — 1.  How  large  is  the  tree-frog?  What  is  its  color? 
Describe  the  markings. 

2.  Place  the  tree-frog  on  some  light-colored  surface  like  a piece  of 
white  blotting  paper.  Note  if  it  changes  color  after  a half  hour.  Later 
place  it  upon  some  dark  surface.  Note  if  it  changes  color  again.  How 
does  this  power  of  changing  color  benefit  the  tree-frog?  Place  a tree-frog 
on  a piece  of  bark.  After  a time  is  it  noticeable? 

3.  Describe  the  eyes.  Note  how  little  the  tree-frog  turns  its  head 
to  see  anything  behind  it.  Describe  its  actions  if  its  attention  is  attracted 
to  anything.  What  color  is  the  pupil?  The  iris? 

4.  Note  the  movement  of  breathing.  Where  does  this  show  the  most  ? 
Examine  the  delicate  membrane  beneath  the  throat.  What  has  this  to 
do  with  the  breathing? 

5.  What  is  the  tree-frog’s  note?  At  what  time  of  day  does  it  peep? 
At  what  time  of  year?  Describe  how  the  frog  looks  when  peeping. 

6.  How  does  the  tree-frog  climb?  When  it  is  climbing  up  a vertical 
surface  study  its  toes.  How  many  on  the  front  foot?  How  are  they 
arranged  ? How  many  toes  on  the  hind  foot  ? Sketch  the  front  and  hind 
feet.  How  do  the  toe-discs  look  when  pressed  against  the  glass?  How 
does  it  manage  to  make  the  discs  cling  and  then  let  go?  Are  there  any 
more  discs  on  the  under  side  of  the  toes?  Is  there  a web  between  the  toes 
of  the  hind  feet  ? Of  the  front  feet  ? 

7.  Look  at  a tree-frog  very  closely  and  describe  its  nostrils  and  its  ears. 

8.  Are  the  tree-frogs  good  jumpers?  What  is  the  size  and  length  of 
the  hind  legs  as  compared  with  the  body? 

9.  When  and  where  are  the  eggs  of  the  tree-frog  laid?  How  do  they 
look? 

10.  How  do  the  tree-frog  tadpoles  differ  from  other  tadpoles? 
Describe  them  if  you  have  ever  seen  them.  In  what  situations  do  they 
live? 

11.  Of  what  use  are  the  tree-frogs  to  us?

Bullfrog. 

THE  FROG 
Teacher's  Story 

E stroller  along  brooksides,  is  likely  to  be  surprised 
some  day,  at  seeing  a bit  of  moss  and  earth  suddenly 
make  a high  leap  and  a far  one,  without  apparent 
provocation.  An  investigation  resolves  the  clump  of 
moss  into  a brilliantly  green  and  yellow,  striped  frog, 
and  then  the  stroller  wonders  how  he  could  have  over- 
looked such  an  obvious  creature.  But  the  leopard 
frog  is  only  obvious  when  it  is  out  of  its  environment. 
The  common  green  frog  is  quite  as  well  protected  since  its  color  is  exactly 
that  of  green  pools.  Most  frogs  spend  their  lives  in  or  about  water,  and 
if  caught  on  land,  they  make  great  leaps  to  reach  their  native  element; 
the  leopard  frog  and  a few  other  species  sometimes  wander  far  afield. 

In  form,  the  frog  is  more  slim  than  the  toad,  and  is  not  covered  with 
great  warts;  it  is  cold  and  slippery  to  the  touch.  The  frog’s  only  chance 
of  escaping  its  enemies,  is  through  the  slipperiness  of  its  body  and  by 
making  long,  rapid  leaps.  As  a jumper,  the  frog  is  much  more  powerful 
than  the  toad  because  its  hind  legs  are  so  much  larger  and  more  muscular, 
in  comparison  with  its  size.  The  first  toe  in  the  front  feet  of  the  leopard 
frog  is  much  swollen,  making  a fat  thumb ; the  mechanics  of  the  hind  legs 
make  it  possible  for  the  frog  to  feather  the  webbed  feet  as  it  swims.  On 
the  bottom  of  the  toes  are  hardened  places  at  the  joints,  and  sometimes 
others  besides,  which  give  the  foot  a strong  hold  when  pushing  for  the 
jump.  The  toe  tips,  when  they  are  pressed  against  the  glass,  resemble 
slightly  the  tree-toads’  discs.  The  hind  foot  is  very  long,  while  on  the 
front  foot  the  toes  radiate  almost  in  a circle.  The  foot  and  leg  are 
colored  like  the  back  of  the  body  above,  and  on  the  under  side  resemble 
the  under  parts.

Handbook  of  Nature-Study 


The  frog  is  likely  to  be  much  more  brightly  colored  than  the  toad,  and 
usually  has  much  of  green  and  yellow  in  its  dress.  But  the  frog  lives 
among  green  things,  while  it  is  to  .the  toad’s  advantage  to  be  the  color  of 
the  soil.  Frogs  also  have  the  chameleon  power  of  changing  color,  to 
harmonize  with  their  environment.  I have  seen  a very  green  leopard 
frog  change  to  a slate-gray  when  placed  upon  slate-colored  rock.  The 
change  took  place  in  the  green  portions.  The  common  green  frog  will 
likewise  change  to  slate-color,  in  a similar  situation.  A leopard  frog 
changed  quickly  from  dark  green  to  pale  olive,  when  it  was  placed  in  the 
water  after  having  been  on  the  soil. 

The  eyes  of  frogs  are  very  prominent,  and  are  beautiful  when  observed 
closely.  The  green  frog  has  a dark  bronze  iris  with  a gleaming  gold  edge 
around  the  pupil,  and  around  the  outer  margin.  The  eye  of  the  leopard 
frog  is  darker;  the  iris  seems  to  be  black,  with  specks  of  ruddy  gold 
scattered  through  it,  and  there  is  an  outer  band  of  red-gold  around  the 
margin.  When  the  frog  winks,  the  nictitating  membrane  rises  from 
below  and  covers  the  whole  eye ; and  when  the  frog  makes  a special  effort 
of  any  sort,  it  has  a comical  way  of  drawing  its  eyes  back  into  its  head. 
When  trying  to  hide  at  the  bottom  of  the  aquarium,  the  leopard  species 
lets  the  eye-lids  fall  over  the  eyes,  so  that  they  do  not  shine  up  and  attract 
pursuers. 

The  ear  is  in  a similar  position  to  that  of  the  toad,  and  in  the  bullfrog, 
is  larger  than  the  eye.  In  the  green  frog,  it  is  a dull  grayish  disc,  almost 
as  large  as  the  eye.  In  the  leopard  frog,  it  is  not  so  large  as  the  eye,  and 
has  a giltish  spot  at  the  center. 

The  nostrils  are  small  and  are  closed  when  below  the  water,  as  may  be 
easily  seen  by  a lens.  The  mouth  opens  widely,  the  comers  extending 
back  under  the  eye.  The  jaws  are  homy  and  are  armed  with  teeth, 
which  are  for  the  purpose  of  biting  off  food  rather  than  for  chewing  it. 
When  above  water,  the  throat  keeps  up  a rythmic  motion  which  is  the 
process  of  breathing;  but  when  below  water  this  motion  ceases.  The 
food  of  frogs  is  largely  composed  of  insects,  that  frequent  damp  places 
or  that  live  in  the  water. 

The  sound-sacs  of  the  frogs,  instead  of  being  beneath  the  throat,  as  is 
the  case  with  toads  and  tree-frogs,  are  at  the  side  of  the  throat;  and  when 
inflated,  may  extend  from  just  back  of  the  eyes,  out  above  the  front  legs. 
The  song  is  characteristic,  and  pleasant  to  listen  to,  if  not  too  close  by. 
Perhaps  exception  should  be  made  to  the  lay  of  the  bullfrog,  which  like 
the  song  of  some  noted  opera  singers,  is  more  wonderful  than  musical; 
the  boom  of  the  bullfrog  makes  the  earth  fairly  quake.  If  we  seize  the 
frog  by  the  hind  leg,  it  will  usually  croak  and  thus  demonstrate  for  us, 
the  position  of  its  sound-sacs. 

In  addition  to  the  snakes,  the  frogs  have  inveterate  enemies  in  the 
herons  which  frequent  shallow  water,  and  eat  them  in  great  numbers. 
The  frogs  hibernate  in  mud  and  about  ponds,  burrowing  deep  enough  to 
escape  freezing.  In  the  spring,  they  come  up  and  sing  their  spring  songs 
and  the  mother  frogs  lay  their  eggs  in  masses  of  jelly  on  the  bottom  of  the 
pond,  usually  where  the  water  is  deeper  than  in  the  situations  where  the 
toads’  eggs  are  laid.  The  eggs  of  the  two  can  always  be  distinguished, 
since  the  toads’  are  laid  in  strings  of  jelly,  while  the  frogs’  are  laid  in  masses. 

It  is  amusing  to  watch  with  a lens,  the  frog  tadpoles  seeking  for  their 
microscopic  food  along  the  glass  of  the  aquarium.  There  are  horny

upper  and  lower  jaws,  the  latter  being  below  and  back  of  the  former.  The 
upper  jaw  moves  back  and  forth  slightly  and  rythmically,  but  the  drop- 
ping of  the  lower  jaw  opens  the  mouth.  There  are  three  rows  of  tiny 
black  teeth  below  the  mouth  and  one  row  above ; at  the  sides  and  below 
these  teeth  are  little,  finger-like  fringes.  Fringes,  rows  of  teeth  and  jaws 
all  work  together,  up  and  down,  out  and  in,  in  the  process  of  breathing. 
The  nostrils,  although  minute,  are  present  in  the  tadpole  in  its  early 
stages.  The  pupil  of  the  eye  is  almost  circular  and  the  iris  is  usually 
yellow  or  copper-bronze,  with  black  mottling.  The  eyes  do  not  wink  nor 
withdraw.  The  breathing-pore  on  the  left  side,  is  a hole  in  a slight 
protuberance. 

At  first,  the  tadpoles  of  the  frogs  and  toads  are  very  much  alike ; but 
later,  most  of  the  frog  tadpoles  are  lighter  in  color,  usually  being  olive- 
green,  mottled  with  specks  of  black  and  white.  The  frog  tadpoles  usually 
remain  much  longer  than  the  toads  in  the  tadpole  stage,  and  when  finally 
they  change  to  adults,  they  are  far  larger  in  size  than  the  toads  are,  when 
they  attain  their  jumping  legs.

LESSON  XLVII 
The  Frog 


Leading  thought — The  frog  lives  near  or  in  ponds  or  streams.  It  is  a 
powerful  jumper  and  has  a slippery  body.  Its  eggs  are  laid  in  masses  of 
jelly  at  the  bottom  of  ponds. 

Method — The  frog  may  be  studied  in  its  native  situation  by  the  pupils 
or  it  may  be  brought  to  the  school  and  placed  in  an  aquarium ; however, 
to  make  a frog  aquarium  there  needs  to  be  a stick  or  stone  projecting 
above  the  water,  for  the  frog  likes  to  spend  part  of  the  time  entirely 
out  of  water  or  only  partially  submerged. 

Observations — 1.  Where  is  the  frog  found?  Does  it  live  all  its  life  in 
the  water?  When  found  on  land  how  and  where  does  it  seek  to  escape? 

2.  Compare  the  form  of  the  frog  with  that  of  the  toad.  Describe 
the  skin,  its  color  and  texture.  Compare  the  skin  of  the  two. 

3.  Describe  the  colors  and  markings  of  the  frog  on  the  upper  and 
on  the  under  side.  How  do  these  protect  it  from  observation  from  above  ? 
From  below?  How  do  we  usually  discover  that  we  are  in  the  vicinity  of  a 
frog? 

4.  Describe  the  frog’s  ears,  eyes,  nostrils  and  mouth. 

5.  Compare  its  “hands  and  feet”  with  those  of  the  toad.  Why  the 
difference  in  the  hind  legs  and  feet  ?

6.  How  does  the  frog  feel  to  your  hand?  Is  it  easy  to  hold  him? 
How  does  this  slipperiness  of  the  frog  benefit  it? 

7.  On  what  does  the  frog  feed?  What  feeds  on  it?  How  does  it 
escape  its  enemies? 

8.  What  sounds  does  the  frog  make?  Where  are  its  sound  sacs 
located  ? How  do  they  look  when  they  are  inflated  ? 

9.  Is  the  frog  a good  swimmer?  Is  it  a better  jumper  than  the  toad? 
Why? 

10.  Where  are  the  frog’s  eggs  laid?  How  do  they  look? 

11.  Can  you  tell  the  frog  tadpoles  from  those  of  the  toad?  Which 
remains  longer  in  the  tadpole  stage?  Study  the  frog  tadpoles,  following 
the  questions  given  in  Lesson  XLIV. 

12.  What  happens  to  the  frog  in  winter? 


FESTINA  LENTE 


Once  on  a time  there  was  a pool 
Fringed  all  about  with  flag-leaves  cool 
And  spotted  with  cow-lilies  garish, 

Of  frogs  and  pouts  the  ancient  parish. 
Alders  the  creaking  redwings  sink  on, 
Tussocks  that  house  blithe  Bob  o'  Lincoln, 
Hedged  round  the  unassailed  seclusion, 
Where  muskrats  piled  their  cells  Carthu- 
sian; 

And  many  a moss-embroidered  log, 

The  watering-place  of  summer  frog, 

Slept  and  decayed  with  patient  skill. 

As  watering-places  sometimes  will. 

Now  in  this  Abbey  of  Theleme, 

Which  realized  the  fairest  dream 
That  ever  dozing  bull-frog  had, 

Sunned,  on  a half-sunk  lily  pad, 

There  rose  a party  with  a mission 
To  mend  the  polliwog's  condition. 

Who  notified  the  selectmen 
To  call  a meeting  there  and  then. 

“Some  kind  of  steps,”  they  said,  “are 
needed; 

They  don't  come  on  so  fast  as  we  did: 

Let's  dock  their  tails;  if  that  don't  make 
'em 

Frogs  by  brevet,  the  Old  One  take  'em! 

That  boy,  that  came  the  other  day 
To  dig  some  flag-root  down  this  way. 

His  jack-kniffe  left,  and  'tis  a sign 
That  Heaven  approves  of  our  design: 

'T  were  wicked  not  to  urge  the  step  on, 
When  Providence  has  sent  the  weapon.”. 
Old  croakers,  deacons  of  the  mire, 

That  led  the  deep  batrachian  choir, 

“Uk!  Uk!  Caronk!”  with  bass  that  might 
Have  left  Lablache’s  out  of  sight, 

Shook  nobby  heads,  and  said  “No,  go! 
You'd  better  let  'em  try  to  grow: 

Old  Doctor  Time  is  slow,  but  still 
He  does  know  how  to  make  a pill.” 

But  vain  was  all  their  hoarsest  bass. 
Their  old  experience  out  of  place, 

And  spite  of  croaking  and  entreating 


The  vote  was  carried  in  marsh-meeting. 
“Lord  knows,  ” protest  the  polliwogs, 

“ We're  anxious  to  be  grown-up  frogs; 

But  don't  push  in  to  do  the  work 
Of  Nature  till  she  prove  a shirk; 

'Tis  not  by  jumps  that  she  advances. 

But  wins  her  way  by  circumstances; 
Pray,  wait  awhile,  until  you  know 
We're  so  contrived  as  not  to  grow; 

Let  Nature  take  her  own  direction, 

And  she'll  absorb  our  imperfection; 

You  mightn't  like  'em  to  appear  with. 

But  we  must  have  the  things  to  steer  with.” 
“No,”  piped  the  party  of  reform, 

“All  great  results  are  ta'en  by  storm; 

Fate  holds  her  best  gifts  till  we  show 
We've  strength  to  make  her  let  them  go; 
The  Providence  that  works  in  history, 

And  seems  to  some  folks  such  a mystery, 
Does  not  creep  slowly  on,  incog., 

Biit  moves  by  jumps,  a mighty  frog; 

No  more  reject  the  Age's  chrism. 

Your  queues  are  an  anachronism; 

No  more  the  future's  promise  mock, 

But  lay  your  tails  upon  the  block. 
Thankful  that  we  the  means  have  voted 
To  have  you  thus  to  frogs  promoted.” 

The  thing  was  done,  the  tails  were  cropped. 
And  home  each  philotadpole  hopped, 

In  faith  rewarded  to  exult, 

And  wait  ihe  beautiful  result. 

Too  soon  it  came;  our  pool,  so  long 
The  theme  of  patriot  bull-frog's  song, 

Next  day  was  reeking,  fit  to  smother, 

With  heads  and  tails  that  missed  each 
other, — 

Here  snoutless  tails,  there  tailless  snouts; 
The  only  gainers  were  the  pouts.

THE  NEWT,  EFT,  OR  SALAMANDER 

Teacher's  Story 

FTER  a rain  in  spring  or  summer,  we  see  these  little  orange-red 
creatures  sprawling  along  roads  or  woodland  paths,  and 
since  they  are  rarely  seen  except  after  rain,  the  wise  people 
of  old,  declared  they  rained  down,  which  was  an  easy  way 
for  explaining  their  presence.  But  the  newts  do  not  rain 
down,  they  rain  up  instead,  since  if  they  have  journeys  to  make  they 
must  needs  go  forth  when  the  ground  is  wet,  otherwise  they  would  dry 
up  and  die.  Thus,  the  newts  make,  a practice  of  never  going  out  except 
when  it  rains.  A closer  view  of  the  eft  shows  plenty  of  peculiarities 
in  its  appearance  to  interest  us.  Its  colors  are  decidedly  gay,  the  body 
color  being  orange,  ornamented  with  vermilion  dots  along  each  side  of 
the  back,  each  red  dot  margined  with  tiny  black  specks;  but  the  eft  is 
careless  about  these  decorations  and  may  have  more  spots  on  one  side 
than  on  the  other.  Besides  these  vermilion  dots,  it  is  also  adorned 
with  black  specks  here  and  there,  and  especially  along  its  sides  looks  as 
if  it  had  been  peppered.  The  newt’s  greatest  beauty  lies  in  its  eyes; 
these  are  black,  with  elongated  pupils,  almost  parallel  with  the  length  of 
the  head,  and  bordered  above  and  below  with  bands  of  golden,  shining  iris 
which  give  the  eyes  a fascinating  brilliancy.  The  nostrils  are  mere  pin- 
holes in  the  end  of  the  snout. 

The  legs  and  feet  look  queerly  inadequate  for  such  a long  body,  since 
they  are  short  and  far  apart.  There  are  four  toes  on  the  front  feet  and 
five  on  the  hind  feet,  the  latter  being  decidedly  pudgy,  The  legs  are 
thinner  where  they  join  the  body  and  wider  toward  the"  feet.  The  eft 
can  move  very  rapidly  with  its  scant  equipment  of  legs.  It  has  a mis- 
leading way  of  remaining  motionless  for  a long  time  and  then  darting 
forward  like  a flash,  its  long  body  falling  into  graceful  curves  as  it  moves. 
But  it  can  go  very  slowly  when  exploring;  it  then  places  its  little  hands 
cautiously  and  lifts  its  head  as  high  as  its  short  arms  will  allow,  in  order  to 
take  observations.  Although  it  can  see  quite  well,  yet  on  an  unusual 
surface,  like  glass,  it  seems  to  feel  the  way  by  touching  its  lower  lip  to  the 
surface  as  if  to  test  it.  The  tail  is  flattened  at  the  sides  and  is  used  to 
twine  around  objects  in  time  of  need;  and  I am  sure  it  is  also  used  to  push 
the  eft  while  crawling,  for  it  curves  this  way  and  that  vigorously,  as  the 
feet  progress,  and  obviously  pushes  against  the  ground.  Then,  too,  the 
tail  is  an  aid  when,  by  some  chance,  the  eft  is  turned  over  on  its  back,  for 
with  its  help,  it  can  right  itself  speedily.  The  eft’s  method  of  walking  is 
interesting;  it  moves  forward  one  front  foot  and  then  the  hind  foot  on 
the  other  side;  after  a stop  for  rest,  it  begins  just  where  it  left  off  when 
it  again  starts  on.  Its  beautiful  eyes  seem  to  serve  the  newt  well  indeed, 
for  I find  that,  when  it  sees  my  face  approaching  the  moss  jar,  it  climbs 
promptly  over  to  the  other  side.  There  are  no  eyelids  for  the  golden 
eyes,  but  the  eft  can  pull  them  back  into  its  head  and  close  the  slit  after 
them,  thus  making  them  very  safe. 

The  eft  with  whose  acquaintance  I was  most  favored,  was  not  yet 
mature  and  was  afraid  of  earthworms ; but  he  was  very  fond  of  plant-lice 
and  it  was  fun  to  see  the  little  creature  stalking  them.  A big  rose  plant- 
louse  would  be  squirming  with  satisfaction  as  it  sucked  the  juice  of  the 
leaf,  when  the  eft  would  catch  sight  of  it  and  become  greatly

a gulp  or  two  and  all  would  be  over.  If  the  aphid  happened  to  be  a big 
one,  the  eft  made  visible  effort  to  swallow  it.  Sometimes  his  eftship 
would  become  greatly  excited  when  he  first  saw  the  plant-louse,  and  he 
would  sneeze  and  snort  in  a very  comical  way,  like  a dog,  when  eager 
for  game. 

The  following  is  the  history  of  this  species  as  summarized  from  Mrs.  S. 
H.  Gage’s  charming  “Story  of  Little  Red  Spot.”  The  egg  was  laid  in  some 
fresh  water  pond  or  the  still  borders  of  some  stream  where  there  is  a 
growth  of  water  weed.  The  egg,  which  is  about  the  size  of  a small  pea, 
is  fastened  to  a water  plant.  It  is  covered  with  a tough  but  translucent 
envelope,  and  has  at  the  center  a little  yellowish  globule.  In  a little  less 
than  a month  the  eft  hatches,  but  it  looks  very  different  from  the  form 
with  which  we  are  most  familiar.  It  has  gray  stripes  upon  its  sides  and 
three  tiny  bunches  of  red  gills  on  each  side,  just  back  of  its  broad  head. 
The  tail  is  long  and  very  thin,  surrounded  by  a fin ; it  is  an  expert  swim- 
mer and  breathes  water  as  does  a fish.  After  a time,  it  becomes  greenish 
above  and  buff  below,  and  by  the  middle  of  August  it  develops  legs  and 
has  changed  its  form  so  that  it  is  able  to  live  upon  land ; it  no  longer  has 
gills  or  fin ; soon  the  coat  changes  to  the  bright  orange  hue  which  makes 
the  little  creature  so  conspicuous. 

The  newt  usually  keeps  hidden  among  moss,  or  under  leaves,  or  in 
decaying  wood,  or  other  damp  and  shady  places;  but  after  a rain,  when 
the  whole  world  is  damp,  it  feels  confidence  enough  to  go  out  in  the  open, 
and  hunt  for  food.  For  two  and  a half  years  it  lives  upon  land  and  then 
returns  to  the  water.  When  this  impulse  comes  upon  it,  it  may  be  far 
from  any  stream;  but  it  seems  to  know  instinctively  where  to  go.  Soon 
after  it  enters  the  water,  it  is  again  transformed  in  color,  becoming  olive- 
green  above  and  buff  below,  although  it  still  retains  the  red  spots  along 
the  back,  as  mementos  of  its  land  life;  and  it  also  retains  its  pepper-like 
dots.  Its  tail  develops  a fin  which  extends  along  its  back  and  is  some- 
what ruffled.  In  some  mysterious  way  it  develops  the  power  to  again 
breathe  the  air  which  is  mixed  with  water.

The  male  has  the  hind  legs  very  large  and  flat;  the  female  is  lighter 
in  color  and  has  more  delicate  and  smaller  legs.  It  is  here  in  the  water 
that  the  efts  find  their  mates  and  finish  careers  which  must  have  surely 
been  hazardous.  During  its  long  and  varied  life,  the  eft  often  sheds  its 
skin  like  the  snake;  it  has  a strange  habit  of  swallowing  its  cast-off  coat.

2.  Is  the  head  the  widest  part  of  the  body?  Describe  the  eyes,  the 
shape  and  color  of  the  pupil  and  of  the  iris.  How  does  the  eft  wink? 
Do  you  think  it  can  see  well  ? 

3 . Can  you  see  the  nostrils  ? How  does  the  throat  move  and  why  ? 

4.  Are  both  pairs  of  legs  the  same  size  ? How  many  toes  on  the  front 
feet?  How  many  toes  on  the  hind  feet?  Does  the  eft  toe-in  with  its 
front  feet  like  a toad? 

5.  Does  it  move  more  than  one  foot  at  a time  when  walking?  Does  it 
use  the  feet  on  the  same  side  in  two  consecutive  steps  ? After  putting  for- 
ward the  right  front  foot  what  foot  follows  next  ? Can  it  move  backward  ? 

6.  Is  the  tail  as  long  as  the  head  and  body  together?  Is  the  tail 
round  or  flat  at  the  sides  ? How  is  it  used  to  help  the  eft  when  traveling  ? 
Does  the  tail  drag  or  is  it  lifted,  or  does  it  push  by  squirming?

roundings? Do  you  think  it  can  see  and  is  afraid  of  you?

do  people  think  they  rain  down?

its  skin  ? How  many  kinds  of  efts  have  you  seen  ? 

10.  From  what  kind  of  egg  does  the  eft  hatch?  When  is  this  egg 
laid?  How  does  it  look?  On  what  is  it  fastened?

What  part  of  its  life  is  spent  upon  land?  What  changes  take  place  in  its 
form  when  it  leaves  the  water  for  life  upon  land,  and  what  changes  take 
place  in  its  structure  when  it  returns  to  the  water? 


LESSON  XLVIII 

The  Newt,  Eft,  or  “Salamander” 

Leading  thought — The  newts  change  their  form  three 
times  to  fit  different  modes  of  life.  They  are  bom  in  the 
water  and  at  first  have  fins  and  gills  like  fishes.  They  then 
live  on  land,  and  have  lungs  for  breathing  air  and  lose 
their  fins ; later  they  go  back  to  the  water  and  again 
develop  the  power  of  breathing  the  oxygen  contained  in 
water,  and  also  a fin. 

Method — The  little,  orange  eft  or  red-spotted  salaman- 
der may  be  kept  in  an  aquarium  which  has  in  it  an 
object,  as  a stone  or  a clump  of  moss  which  projects  above 
the  water.  For  food  it  should  be  given  small  earthworms 
or  leaves  covered  with  plant  lice.  In  this  way  it  may  be 
studied  at  leisure. 

Observations — 1.  Look  at  the  eft  closely.  Is  it  all  the 
same  color?  How  many  spots  upon  its  back  and  what 
colors  are  they?  Are  there  the  same  number  of  spots  on 
both  sides?  Are  there  any  spots  or  dots  besides  these

Yet  when  a child  and  barefoot;  I more  than  once,  at  morn.

the  teacher  could  bring  herself  to  take  as  much  interest  as 
did  Mother  Eve  in  that  “subtile  animal,”  as  the  Bible  calls 
the  serpent,  she  might,  through  such  interest,  enter  the 
paradise  of  the  boyish  heart  instead  of  losing  a paradise  of 
her  own.  How  many  teachers,  who  have  an  aversion  for 
snakes,  are  obliged  to  teach  small  boys  whose  pet  diversion 
is  capturing  these  living  ribbons  and  bringing  them  into 
the  schoolroom  stowed  away  not  too  securely  in  pockets! 
In  one  of  the  suburban  Brooklyn  schools,  boys  of  this  ilk  sought  to 
frighten  their  teacher  with  their  weird  prisoners.  But  she  was  equal  to 
the  occasion,  and  surprised  them  by  declaring  that  there  were  many 
interesting  things  to  be  studied  about  snakes,  and  forthwith  sent  to  the 
library  for  books  which  discussed  these  reptiles ; and  this  was  the  begin- 
ning of  a nature-study  club  of  rare  efficiency  and  enterprise. 

There  are  abroad  in  the  land,  many  errors  concerning  snakes.  Most 
people  believe  that  they  are  all  venomous,  which  is  far  from  true.  The 
rattlesnake  still  holds  its  own  in  rocky,  mountainous  places  and  the 
moccasin  haunts  the  bayous  of  the  southern  coast;  however,  in  most 
localities,  snakes  are  not  only  harmless  but  are  beneficial  to  the  farmer. 
The  superstition  that  if  a snake  is  killed,  its  tail  will  live  until  sun-down,  is 
general  and  has  but  slender  foundation  in  the  fact  that  snakes,  being 
lower  in  their  nerve-organization  than  mammals,  the  process  of  death  is  a 
slow  one.  Some  people  firmly  believe  that  snakes  spring  or  jump  from 
the  ground  to  seize  their  prey,  which  is  quite  false  since  no  snake  jumps 
clear  of  the  ground  as  it  strikes,  nor  does  it  spring  from  a perfect  coil. 
Nor  are  snakes  slimy,  quite  to  the  contrary,  they  are  covered  with  per- 
fectly dry  scales.  But  the  most  general  superstition  of  all  is  that,  when 
a snake  thrusts  out  its  tongue,  it  is  an  act  of  animosity;  the  fact  is,  the 
tongue  is  a sense  organ  and  is  used  as  an  insect  uses  its  feelers  or  antennae, 
and  the  act  is  also  supposed  to  aid  the  creature  in  hearing;  thus  when  a 
snake  thrusts  out  its  tongue,  it  is  simply  trying  to  find  out  about  its  sur- 
roundings and  what  is  going  on. 

Snakes  are  the  only  creatures  able  to  swallow  objects  larger  than 
themselves.  This  is  rendered  possible  by  the  elasticity  of  the  body  walls, 
and  the  fact  that  snakes  have  an  extra  bone  hinging  the  upper  to  the  lower 
jaw,  allowing  them  to  spread  widely;  the  lower  jaw  also  separates  at  the 
middle  of  its  front  edge  and  spreads  apart  sidewise.  In  order  to  force  a 
creature  into  a “bag”  so  manifestly  too  small,  a special  mechanism  is 
needed;  the  teeth  supply  this  by  pointing  backward,  and  thus  assist  in 
the  swallowing.  The  snake  moves  by  literally  walking  on  the  ends  of  its 
ribs,  which  are  connected  with  the  crosswise  plates  on  its  lower  side;  each 
of  these  crosswise  plates  has  the  hind  edge  projecting  down  so  that  it  can 
hold  to  an  object.  Thus,  the  graceful,  noiseless  progress  of  the  snake,  is 
brought  about  by  many  of  these  crosswise  plates  worked  by  the  move- , 
ment  of  the  ribs.

Some  species  of  snakes  simply  chase  their  prey,  striking  at  it  and 
catching  it  in  the  open  mouth,  while  others,  like  the  black  snake,  wind 
themselves  about  their  victims  crushing  them  to  death.  Snakes  can  live 
a long  time  without  food ; many  instances  on  record  show  that  they  have 
been  able  to  exist  a year  or  more  without  anything  to  eat.  In  our  north- 
ern climate  they  hibernate  in  winter,  going  to  sleep  as  soon  as  the  weather 
becomes  cold  and  not  waking  up  until  spring.  As  snakes  grow,  they 
shed  their  skins;  this  occurs  only  two  or  three  times  a year.  The  crested 
fly-catcher  adorns  its  nest  with  these  phantom  snakes. 

References — The  Reptile  Book,  by  Ditmars,  gives  interesting  accounts 
of  our  common  snakes;  Mathew’s  Familiar  Life  of  Field  and  Forest  is 
also  valuable.  To  add  interest  to  the  snake  lessons  let  the  children  read 
“Kaas  Hunting”  and  “Rikki  TikkiTavi”  from  Kipling’s  Jungle  Books. 


THE  GARTER,  OR  GARDEN,  SNAKE 
Teacher's  Story 

A chipmunk,  or  a sudden-whirring  quail, 

Is  startled  by  my  step  as  on  I fare. 

A gartersnake  across  the  dusty  trail , 

Glances  and  — is  not  there . — Riley. 


jARTER  snakes  can  be  easily  tamed,  and  are  ready  to  meet 
friendly  advances  'half  way.  A handsome  yellow-striped, 
black  garter  lived  for  four  years  beneath  our  piazza  and 
was  very  friendly  and  unafraid  of  the  family.  The 
children  of  the  campus  made  it  frequent  visits,  and  never 
seemed  to  be  weary  of  watching  it ; but  the  birds  objected 
to  it  very  much,  although  it  never  attempted  to  reach  their  nests  in  the 
vine  above.  The  garter  snakes  are  the  most  common  of  all,  in  our  North- 
eastern States.  They  vary  much  in  color;  the  ground  color  may  be  olive, 
brown  or  black,  and  down  the  center  of  the  back  is  usually  a yellow,  green 
or  whitish  stripe,  usually  bordered  by  a darker  band  of  ground-color. 
On  each  side  is  a similar  stripe,  but  not  so  brightly  colored;  sometimes 
the  middle  stripe,  and  sometimes  the  side  stripes  are  broken  into  spots  or 
absent;  the  lower  side  is  greenish  white  or  yellow.  When  fully  grown 
this  snake  is  about  three  feet  in  length. 

The  garters  are  likely  to  congregate  in  numbers  in  places  favorable 
for  hibernation,  like  rocky  ledges  or  stony  side-hills.  Here  each  snake 
finds  a safe  crevice,  or  makes  a burrow  which  sometimes  extends  a yard 
or  more  under  ground.  During  the  warm  days  of  Indian  summer,  these 
winter  hermits  crawl  out  in  the  middle  of  the  day  and  sun  themselves, 
retiring  again  to  their  hermitages  when  the  air  grows  chilly  toward  night ; 
and  when  the  cold  weather  arrives,  they  go  to  sleep  and  do  not  awaken 
until  the  first  warm  days  of  spring;  then,  if  the  sun  shines  hot,  they 
crawl  out  and  bask  in  its  welcome  rays. 

After  the  warm  weather  comes,  the  snakes  scatter  to  other  localities 
more  favorable  for  finding  food,  and  thus  these  hibernating  places  are 
deserted  during  the  summer.  The  banks  of  streams,  and  the  edges  of 
woods  are  places  which  furnish  snakes  their  food,  which  consists  of  earth- 
worms, insects,  toads,  salamanders,  frogs,  etc.  The  young  are  born  late

her  brood  from  eleven  to  fifty  snakelings;  she  stays  with  them  during 
the  fall  to  protect  them,  and  there  are  many  stories  about  the  way  the 
young  ones  run  down  the  mother’s  throat  in  case  of  attack;  but,  as  yet, 
no  scientist  has  seen  this  act,  or  placed  it  on  record.  The  little  snakes 
shift  for  their  own  food,  catching  small  toads,  earthworms  and  insects. 
If  it  finds  food  in  plenty,  the  garter  snake  will  mature  in  one  year. 
Hawks,  crows,  skunks,  weasels  and  other  predacious  animals  seem  to  find 
the  garter  snake  attractive  food.

LESSON  XLIX 

The  Garter,  or  Garden,  Snake 

Leading  thought — The  garter  snake  is  a common  and  harmless  little 
creature  and  has  many  interesting  habits  which  are  worth  studying. 

Method — A garter  snake  may  be  captured  and  placed  in  a box  with  a 
glass  cover  and  thus  studied  in  detail  in  the  schoolroom,  but  the  lesson 
should  begin  with  observations  made  by  the  children  on  the  snakes  in 
their  native  haunts. 

Observations — i.  What  are  the  colors  and  markings  of  your  garter 
snake?  Do  the  stripes  extend  along  the  head  as  well  as  the  body  ? How 
long  is  it? 

2.  Describe  its  eyes,  its  ears,  its  nostrils  and  its  mouth, 

3.  If  you  disturb  it  how  does  it  act?  Why  does  it  thrust  its  tongue 
out?  What  shape  is  its  tongue?

4.  In  what  position  is  the  snake  when  it  rests?  Can  you  see  how 
it  moves?  Look  upon  the  lower  side.  Can  you  see  the  little  plates 
extending  crosswise?  Do  you  think  it  moves  by  moving  these  plates? 
Let  it  crawl  across  your  hand,  and  see  if  you  can  tell  how  it  moves. 

5.  What  does  the  garter  snake  eat?  Did  you  ever  see  one  swallow 
a toad?  A frog?  Did  it  take  it  head  first  or  tail  first ? 

6.  Where  does  the  garter  spend  the  winter?  How  early  does  it 
appear  in  the  spring? 

7 . At  what  time  of  year  do  you  see  the  young  snakes  ? Do  the  young 
ones  run  down  the  throat  of  the  mother  for  safety  when  attacked  ? Does 
the  mother  snake  defend  her  young? 

8.  What  enemies  has  the  garter  snake? 


“No  life  in  earth  or  air  or  sky; 

The  sunbeams,  broken  silently. 

On  the  bared  rocks  around  me  lie, — 

Cold  rocks  with  half-warmed  lichens  scarred , 

And  scales  of  moss;  and  scarce  a yard 
Away,  one  long  strip,  yellow-barred. 

Lost  in  a cleft!  ’ T is  but  a stride 
To  reach  it,  thrust  its  roots  aside, 

And  lift  it  on  thy  stick  astride! 

Yet  stay!  That  moment  is  thy  grace! 

For  round  thee,  thrilling  air  and  space, 

A chattering  terror  fills  the  place! 

A sound  as  of  dry  bones  that  stir, 

In  the  dead  valley!  By  yon  fir 
The  locust  stops  its  noon-day  whir! 

The  wild  bird  hears;  smote  with  the  sound. 

As  if  by  bullet  brought  to  ground 
On  broken  wing,  dips,  wheeling  round! 

The  hare,  transfixed,  with  trembling  lip. 

Halts  breathless,  on  pulsating  hip, 

And  palsied  tread,  and  heels  that  slip. 

Enough,  old  friend! — His  thou.  Forget 
My  heedless  foot,  nor  longer  fret 
The  peace  with  thy  grim  castanet!”

THE  MILK  SNAKE,  OR  SPOTTED  ADDER 

Teacher's  Story 

The  grass  divides  as  with  a comb,  a spotted  shaft  is  seen, 

And  then  it  closes  at  your  feet,  and  opens  farther  on. 

— Emils  Dickinson. 

| HIS  is  the  snake  which  is  said  to  milk  cows,  a most 
absurd  belief;  it  would  not  milk  a cow  if  it  could,  and 
it  could  not  if  it  would.  It  has  never  yet  been  induced 
to  drink  milk  when  in  captivity ; and  if  it  were  very 
thirsty,  it  could  not  drink  more  than  two  teaspoonfuls 
of  milk  at  most;  thus  in  any  case,  its  depredations 
upon  the  milk  supply  need  not  be  feared.  Its  object, 
in  frequenting  milk  houses  and  stables,  is  far  other  than 
the  milking  of  cows,  for  it  is  an  inveterate  hunter  of 
rats  and  mice  and  is  thus  of  great  benefit  to  the  farmer.  It  is  a constric- 
tor, and  squeezes  its  prey  to  death  in  its  coils. 

The  ground  color  of  the  milk  snake  is  pale  gray,  but  it  is  covered  with 
so  many  brown  or  dark  gray  saddle-shaped  blotches,  that  they  seem 
rather  to  form  the  ground-color;  the  lower  side  is  white,  marked  with 
square  black  spots  and  blotches.  The  snake  attains  a length  of  about 
three  feet  when  fully  grown.  Although  it  is  called  commonly  the  spotted 
adder,  it  does  not  belong  to  the  adders  at  all,  but  to  the  family  of  the  king 
snakes. 

During  July  and  August,  the  mother  snake  lays  from  seven  to  twenty 
eggs;  they  are  deposited  in  loose  soil,  in  moist  rubbish,  in  compost  heaps, 
etc.  The  egg  is  a symmetrical  oval  in  shape  and  is  about  one  and  one- 
eighth  inches  long  by  a half  inch  in  diameter.  The  shell  is  soft  and  white, 
like  kid  leather,  and  the  egg  resembles  a puffball.  The  young  hatch 
nearly  two  months  after  the  eggs  are  laid,  meanwhile  the  eggs  have  in- 
creased in  size  so  that  the  snakelings  are  nearly  eight  inches  long  when  they 
hatch.  The  saddle-shaped  blotches  on  the  young  have  much  red  in  them. 
The  milk  snake  is  not  venomous;  it  will  sometimes,  in  defence,  try  to 
chew  the  hand  of  the  captor,  but  the  wounds  it  can  inflict  are  very  slight 
and  heal  quickly.

LESSON  L. 

The  Milk  Snake,  or  Spotted  Adder 

Leading  thought — The  milk  snake  is  found  around  stables  where  it 
hunts  for  rats  and  mice  but  never  milks  the  cows. 

Method — Although  the  snake  acts  fiercely,  it  is  perfectly  harmless  and 
maybe  captured  in  the  hands  and  placed  in  a glass-covered  box  for  a study 
in  the  schoolroom. 

Observations — i.  Where  is  the  milk  snake  found?  Why  is  it  called 
milk  snake?  Look  at  its  mouth  and  see  if  you  think  it  could  possibly 
suck  a cow.  See  if  you  can  get  the  snake  to  drink  milk. 

2.  What  does  it  live  upon?  How  does  it  kill  its  prey?  Can  the 
milk  snake  climb  a tree? 

3 . Where  does  the  mother  snake  lay  her  eggs  ? How  do  the  eggs 
look?  How  large  are  they?  How  long  are  the  little  snakes  when  they 
hatch  from  the  egg?  Are  they  the  same  color  as  the  old  ones? 

4.  Describe  carefully  the  colors  and  markings  of  the  milk  snake  and 
explain  how  its  colors  protect  it  from  observation.  What  are  its  colors  on 
the  under  side? 

5.  Have  you  ever  seen  a snake  shed  its  skin?  Describe  how  it  was 
done.  How  does  the  sloughed-off  skin  look?  What  bird  always  puts 
snake  skins  around  its  nest? 


I have  the  same  objection  to  killing  a snake  that  I have  to  the  killing  of  any  other 
animal,  yet  the  most  humane  man  l know  never  omits  to  kill  one. 

Aug.  5,  1853. 

The  mower  on  the  river  meadows,  when  he  comes  to  open  his  hay  these  days,  en- 
counters some  overgrown  water  adder,  full  of  young  (?)  and  bold  in  defense  of  its 
progeny,  and  tells  a tale  when  he  comes  home  at  night  which  causes  a shudder  to  run 
through  the  village — how  it  came  at  him  and  he  ran,  and  it  pursued  and  overtook  him, 
and  he  transfixed  it  with  a pitchfork  and  laid  it  on  a cock  of  hay,  but  it  revived  and  came 
at  him  again.  This  is  the  story  he  tells  in  the  shops  at  evening.  The  big  snake  is  a sort 
of  fabulous  animal.  It  is  always  as  big  as  a man's  arm  and  of  indefinite  length. 
Nobody  knows  exactly  how  deadly  is  its  bite  but  nobody  is  known  to  have  been  bitten  and 
recovered.  Irishmen  introduced  into  these  meadows  for  the  first  time,  on  seeing  a snake, 
a creature  which  they  have  seen  only  in  pictures  before,  lay  down  their  scythes  and  run 
as  if  it  were  the  Evil  One  himself  and  cannot  be  induced  to  return  to  their  work.  They 
sigh  for  Ireland,  where  they  say  there  is  no  venomous  thing  that  can  hurt  you.

THE  WATER  SNAKE 
Teacher's  Story 

“VERY  boy  that  goes  fishing,  knows  the  snake  found  com- 
monly about  mill-dams  and  wharves  or  on  rocks  and 
bushes  near  the  water.  The  teacher  will  have  accomplished 
a great  work,  if  these  boys  are  made  to  realize  that  this 
snake  is  a more  interesting  creature  for  study,  than  as  an 
object  to  pelt  with  stones. 

The  water  snake  is  a dingy  brown  in  color,  with  cross- 
bands of  brownish  or  reddish  brown  which  spread  out  into  blotches  at 
the  side.  Its  color  is  very  protective  as  it  lies  on  stones  or  logs  in  its 
favorite  attitude  of  sunning  itself.  It  is  very  local  in  its  habits,  and 
generally  has  a favorite  place  for  basking  and  returns  to  it  year  after 
year  on  sunny  days. 

This  snake  lives  mostly  upon  frogs  and  salamanders  and  fish ; however, 
it  preys  usually  upon  fish  of  small  value,  so  it  is  of  little  economic  import- 
ance. It  catches  its  victims  by  chasing,  and  seizing  them  in  its  jaws. 
It  has  a very  keen  sense  of  smell  and  probably  traces  its  prey  in  this 
manner,  something  as  a hound  follows  a fox.  It  is  an  expert  swimmer, 
usually  lifting  the  head  a few  inches  above  the  water  when  swimming, 
although  it  is  able  to  dive  and  remain  below  the  water  for  a short  time. 

The  water  snake  is  a bluffer,  and,  when  cornered,  it  flattens  itself  and 
strikes  fiercely.  But  its  teeth  contain  no  poison  and  it  can  inflict  only 
slight  and  harmless  wounds.  When  acting  as  if  it  would  “rather  fight  than 
eat,”  if  given  a slight  chance  to  escape,  it  will  flee  to  the  water  like  a 
“streak  of  greased  lightning,”  as  any  boy  will  assure  you.

The  water  snake  attains  a length  of  about  four  feet.  The  young  do 
not  hatch  from  eggs,  but  are  bom  alive  in  August  and  September;  they 
differ  much  in  appearance  from  their  parents  as  they  are  pale  gray  in 
color,  with  jet-black  cross-bands. 

LESSON  LI 
The  Water  Snake 

Leading  thought — The  water  snake  haunts  the  banks  of  streams  because 
its  food  consists  of  creatures  that  live  in  and  about  water. 

Method — If  water  snakes  are  found  in  the  locality,  encourage  the  boys 
to  capture  one  without  harming  it,  and  bring  it  to  school  for  observation. 
However,  as  the  water  snake  is  very  local  in  its  habits,  and  haunts  the 
same  place  year  after  year,  it  will  be  better  nature-study  to  get  the  children 
to  observe  it  in  its  native  surroundings. 

Observations — 1.  Where  is  the  water  snake  found?  How  large  is  the 
largest  one  you  ever  saw? 

2.  Why  does  the  water  snake  live  near  water?  What  is  its  food? 
How  does  it  catch  its  prey? 

3.  Describe  how  the  water  snake  swims.  How  far  does  its  head 
project  above  the  water  when  swimming?  How  long  can  it  stay  com- 
pletely beneath  the  water  ? 

4.  Describe  the  markings  and  colors  of  the  water  snake.  How  do 
these  colors  protect  it  from  observation?  How  do  the  young  look? 

5.  Does  each  water  snake  have  a favorite  place  for  sunning  itself? 

6.  Where  do  the  water  snakes  spend  the  winter? 


May  12,  1858. 

Found  a large  water  adder  by  the  edge  of  Farmer's  large  mudhole , which  abounds 
with  tadpoles  and  frogs,  on  which  it  was  probably  feeding.  It  was  sunning  on  the  bank 
and  would  face  me  and  dart  its  head  toward  me  when  I tried  to  drive  it  from  the  water. 
It  is  barred  above,  but  indistinctly  when  out  of  the  water,  so  that  it  appears  almost 
uniformly  dark  brown,  but  in  the  water,  broad,  reddish  brown  bars  are  seen,  very  dis- 
tinctly alternating  with  very  dark-brown  ones.  The  head  was  very  flat  and  suddenly 
broader  than  the  neck  behind.  Beneath,  it  was  whitish  and  reddish  flesh-color.  It  was 
about  two  inches  in  diameter  at  the  thickest  part.  The  inside  of  its  mouth  and  throat 
was  pink.  They  are  the  biggest  and  most  formidable-looking  snakes  that  we  have.  It 
was  awful  to  see  it  wind  along  the  bottom  of  the  ditch  at  last,  raising  wreaths  of  mud 
amid  the  tadpoles,  to  which  it  must  be  a very  sea-serpent.  I afterward  saw  another , 
running  under  Sam  Barrett's  grist-mill,  the  same  afternoon.  He  said  that  he  saw  a 
water-snake,  which  he  distinguished  from  a black  snake,  in  an  apple  tree  near  by,  last 
year,  with  a young  robin  in  its  mouth,  having  taken  it  from  the  nest.  There  was  a cleft 
or  fork  in  the  tree  which  enabled  it  to  ascend.

THE  TURTLE 
Teacher's  Story 

A TURTLE  is  at  heart  a misanthrope ; its  shell  is  in  itself  proof  of 
/\  its  owner’s  distrust  of  this  world.  But  we  need  not 

— / \ wonder  at  this  misanthropy,  if  we  think  for  a moment 

If  y r — ' of  the  creatures  that  lived  on  this  earth,  at  the  time 

pks  ZfJ!  when  turtles  first  appeared.  Almost  any  of  us  would 
have  been  glad  of  a shell  in  which  to  retire,  if  we  had 
been  contemporaries  of  the  smilodon  and  other  monsters  of  earlier  geologic 
times. 

When  the  turtle  feels  safe  and  walks  abroad  for  pleasure,  Lis  head  pro- 
jects far  from  the  front  end  of  his  shell,  and  the  legs,  so  wide,  and  soft  that 
they  look  as  if  they  had  no  bones  in  them,  project  out  at  the  side,  while 
the  little,  pointed  tail  brings  up  an  undignified  rear;  but  frighten  him 
and  at  once  head,  legs  and  tail  all  disappear,  and  even  if  we  turn  him  over, 
we  see  nothing  but  the  tip  of  the  nose,  the  claws  of  the  feet  and  the  tail 
turned  deftly  sidewise.  When  frightened,  he  hisses  threateningly;  the 
noise  seems  to  be  made  while  the  mouth  is  shut,  and  the  breath  emitted 
through  the  nostrils. 


The  upper  shell  of  the  turtle  is  called  the  carapace  and  the  lower  shell, 
the  plastron.  There  is  much  difference  in  ;the  different  species  of  turtles 
in  the  shape  of  the  upper  shell  and  the  size  and  shape  of  the  lower  one. 
In  most  species  the  carapace  is  sub-globular  but  in  some  it  is  quite  flat. 
The  upper  shell  is  grown  fast  to  the  backbone  of  the  animal,  and  the 
lower  shell  to  the  breast  bone.  The  markings  and  colors  of  the  shell  offer 
excellent  subjects  for  drawing.  The  painted  terrapin  has  a red-mottled 
border  to  the  shell,  very  ornamental;  the  wood  turtle  has  a shell  made  up 
of  plates  each  of  which  is  ornamented  with  concentric  ridges ; and  the  box- 
turtle  has  a front  and  rear  trap-door,  hinged  to  the  plastron,  which  can 
be  pulled  up  against  the  carapace  when  the  turtle  wishes  to  retire,  thus 
covering  it  entirely. .

The  turtle’s  head  is  decidedly  snakelike.  Its  color  differs  with  differ- 
ent species.  The  wood  turtle  has  a triangular,  homy  covering  on  the 
top  of  the  head,  in  which  the  color  and  beautiful  pattern  of  the  shell  are 
repeated;  the  underparts  are  brick-red  with  indistinct  yellowish  lines 
under  the  jaw.  The  eyes  are  black  with  a yellowish  iris,  which  somehow 
gives  them  a look  of  intelligence.  The  turtle  has  no  eyelids  like  our  own, 
but  has  a nictitating  membrane  which  comes  up  from  below  and  com- 
pletely covers  the  eye ; if  we  seize  the  turtle  by  the  head  and  attempt  to 
touch  its  eyes,  we  can  see  the  use  of  this  eyelid.  When  the  turtle  winks, 
it  seems  to  turn  the  eyeball  down  against  the  lower  lid. 

The  sense  of  smell  in  turtles  is  not  well  developed,  as  may  be  guessed 
by  the  very  small  nostrils,  which  are  mere  pin-holes  in  the  snout.  The 
mouth  is  a more  or  less  hooked  beak,  and  is  armed  with  cutting  edges 
instead  of  teeth.  The  constant  pulsation  in  the  throat  is  caused  by  the 
turtle  swallowing  air  for  breathing. 

The  turtle’s  legs,  al- 
though so  large  and  soft, 
have  bones  within  them, 
as  the  skeleton  shows. 

The  claws  are  long  and 
strong;  there  are  five 
claws  on  the  front  and 
four  on  the  hind  feet. 

Some  species  have  a dis- 
tinct web  between  the 
toes;  in  others,  it  is  less 
marked,  depending  upon 
whether  the  species  lives 
mostly  in  water  or  out 
of  it.  The  color  of  the 
turtle’s  body  varies  with 
the  species;  the  body  is 
covered  with  coarse, 
rough  skin  made  up  of 
various-sized  plates. 

The  enemies  of  turtles 
are  the  larger  fishes  and 
other  turtles.  Two  tur- 
tles should  never  be  kept 
in  the  same  aquarium, 
since  they  eat  each 
others’  tails  and  legs  with 
great  relish.  They  feed 
upon  insects,  small  fish, 
or  almost  anything  soft- 
bodied  which  they  can 
find  in  the  water;  they 
are  especially  fond  of. 
earthworms.  The  species  which  frequent  the  land,  feed  upon  tender 
vegetation  and  also  eat  berries.  In  an  aquarium,  a turtle  should  be 
fed  earthworms,  chopped  fresh  beef,  lettuce  leaves  and  berries.  The 
wood  turtle  is  especially  fond  of  cherries.

Handbook  of  Nature-Study 


The  aquarium  should  always  have  in  it  a stone  or  some  other  object 
projecting  above  the  water,  so  that  the  turtle  may  climb  out,  if  it  chooses. 
In  winter,  turtles  bury  themselves  in  the  ooze  at  the  bottom  of  ponds  and 
streams.  Their  eggs  have  white  leathery  shells,  are  oblong  or  round,  and 
are  buried  by  the  mother  in  the  sand  or  soil  near  a stream  or  pond.  The 
long  life  of  turtles  is  a well  authenticated  fact,  dates  carved  upon'  their 
shells  show  them  to  have  attained  the  age  of  thirty  or  forty  years. 

The  following  are,  perhaps,  the  most  common  species  of  turtles: 

(a)  The  Snapping  Turtle — This  sometimes  attains  a shell  14  inches 
long  and  a weight  of  forty  pounds.  It  is  a vicious  creature  and  inflicts  a 
severe  wound  with  its  sharp,  hooked  beak;  it  should  not  be  used  for  a 
nature-study  lesson  unless  the  specimen  is  very  young. 

(b)  The  Mud  Turtle — The  musk  turtle  and  the  common  mud  turtle 
both  inhabit  slow  streams  and  ponds;  they  are  truly  aquatic  and  only 
come  to  shore  to  deposit  their  eggs.  They  cannot  eat,  unless  they  are 
under  water,  and  they  seek  their  food  in  the  muddy  bottoms.  The 
musk  turtle  when  handled,  emits  a very  strong  odor;  it  has  on  each 
side  of  the  head  two  broad  yellow  stripes.  The  mud  turtle  has  no 
odor.  Its  head  is  ornamented  with  greenish  yellow  spots. 

(c)  The  Painted  Terrapin,  or  Pond  Turtle — This  can  be  determined  by 
the  red  mottled  border  of  its  shell.  It  makes  a good  pet,  if  kept  in  an 
aquarium  by  itself,  but  will  destroy  other  creatures.  It  will  eat  meat  or 
chopped  fish,  and  is  fond  of  earthworms  and  soft  insects. 

(d)  The  Spotted  Turtle — This  has  the  upper  shell  black  with  numerous 
round  yellow  spots  upon  it.  It  is  common  in  ponds  and  marshy  streams 
and  its  favorite  perch  is,  with  many  of  its  companions,  upon  a log.  It 
feeds  under  water,  eating  insect  larvae,  dead  fish  and  vegetation.  It 
likes  fresh  lettuce. 

(e)  The  Wood  Terrapin — This  is  our  most  common  turtle;  it  is  found 
in  damp  woods  and  wet  places,  since  it  lives  largely  upon  the  land.  Its 
upper  shell  often  reaches  a length  of  six  and  one-half  inches  and  is  made 
up  of  many  plates,  ornamented  with  concentric  ridges.  This  is  the  turtle 
upon  whose  shell  people  carve  initials  and  dates  and  then  set  it  free.  All 
the  fleshy  parts  of  this  turtle,  except  the  top  of  the  head  and  the  limbs, 
are  brick-red.  It  feeds  on  tender  vegetables,  berries  and  insects.  It 
makes  an  interesting  pet  and  will  soon  learn  to  eat  from  the  fingers  of  its 
master. 

(f)  The  Box-Turtle — This  is  easily  distinguished  from  the  others, 
because  the  front  and  rear  portions  of  the  lower  shell  are  hinged  so  that 
they  can  be  pulled  up  against  the  upper  shell.  When  this  turtle  is 
attacked,  it  draws  into  the  shell  and  closes  both  front  and  back  doors,  and 
is  very  safe  from  its  enemies.  It  lives  entirely  upon  land  and  feeds  upon 
berries,  tender  vegetation  and  insects.  It  lives  to  a great  age. 

(g)  The  Soft-shelled  Turtle — These  are  found  in  streams  and  canals. 
The  upper  shell  looks  as  if  it  were  of  one  piece  of  soft  leather,  and  resem- 
bles a griddle-cake.  Although  soft-shelled,  these  turtles  are  far  from  soft- 
tempered,  and  must  be  handled  with  care.

Leading  thought — 

The  turtle’s  shell  is 
for  the  purpose  of 
protecting  its  owner 
from  the  attack  of 
enemies.  Some  tur- 
tles live  upon  land 
and  others  in  water. 

Method — A turtle 
of  any  kind,  in  the 
schoolroom,  is  all 
that  is  needed  to 
make  this  lesson  in- 
teresting. 

Observatio  ns — 

i .  How  much  can  you 
see  of  the  turtle  when 
it  is  walking?  I f 
you  disturb  it  what 
does  it  do?  How 
much  of  it  can  you 
see  then?  Can  you 
see  more  of  it  from  the 
lower  side  than  the  upper?  What  is  the  advantage  to  the  turtle  of 
having  such  a shell  ? 

2.  Compare  the  upper  shell  with  the  lower  as  follows:  How  are 

they  shaped  differently?  What  is  their  difference  in  color?  Would  it 
be  a disadvantage  to  the  turtle  if  the  upper  shell  were  as  light  colored 
as  the  lower?  Why?  Make  a drawing  of  the  upper  and  the  lower  shell 
showing  the  shape  of  the  plates  of  which  they  are  composed.  Where 
are  the  two  grown  together? 

3.  Is  the  border  of  the  upper  shell  different  from  the  central  portion 
in  color  and  markings?  Is  the  edge  smooth  or  scalloped? 

4.  How  far  does  the  turtle’s  head  project  from  the  front  of  the  shell? 
What  is  the  shape  of  the  head?  With  what  colors  and  pattern  is  it 
marked  ? Describe  the  eyes.  How  are  they  protected  ? How  does  the 
turtle  wink?  Can  you  discover  the  little  eyelid  which  comes  up  from 
below  to  cover  the  eye? 

5.  Describe  the  nose  and  nostrils.  Do  you  think  it  has  a keen  sense 
of  smell? 

6.  Describe  the  mouth.  Are  there  any  teeth?  With  what  does  it 
bite  off  its  food?  Describe  the  movement  of  the  throat.  Why  is  this 
constant  pulsation? 

7.  What  is  the  shape  of  the  leg?  How  is  it  marked?  How  many 
claws  on  the  front  feet  ? Are  any  of  the  toes  webbed  ? On  which 'feet  are 
the  webbed  toes?  Why  should  they  be  webbed?  Describe  the  way  a 
turtle  swims.  Which  feet  are  used  for  oars? 

8.  Describe  the  tail.  How  much  can  be  seen  from  above  when  the 
turtle  is  walking?  What  becomes  of  it,  when  the  turtle  withdraws  into 
its  shell? 


212  Handbook  of  Nature-Study 

9.  How  much  of  the  turtle’s  body  can  you  see?  What  is  its  color? 
Is  it  rough  or  smooth  ? 

10.  What  are  the  turtle’s  enemies?  How  does  it  escape  from  them? 
What  noise  does  the  turtle  make  when  frightened  or  angry? 

11.  Do  all  turtles  live  for  part  of  the  time  in  water?  What  is  their 
food  and  where  do  they  find  it?  Write  an  account  of  all  the  species  of 
turtles  that  you  know. 

12.  How  do  turtle  eggs  look?  Where  are  they  laid ? How  are  they 
hidden  ?

V.  MAMMAL  STUDY 


OR  some  inexplicable  reason,  the  word  animal,  in 
common  parlance,  is  restricted  to  the  mammals. 
As  a matter  of  fact,  the  bird,  the  fish,  the  insect 
and  the  snake  have  as  much  right  to  be  called  animals  as  has 
the  squirrel  or  the  deer.  And  while  I believe  that  much 
freedom  in  the  matter  of  scientific  nomenclature  is  permissible 
in  nature-study,  I also  believe  that  it  is  well  for  the  child  to 
have  a clearly  defined  idea  of  the  classes  into  which  the  animal 
kingdom  is  divided;  and  I would  have  him  gain  this  knowledge 
by  noting  how  one  animal  differs  from  another  rather  than  by 
studying  the  classification  of  animals  in  books.  He  sees 
that  the  fish  differs  in  many  ways  from  the  bird  and  that  the 
toad  differs  from  the  snake;  and  it  will  be  easy  for  him  to  grasp 
the  fact  that  the  mammals  differ  from  all  other  animals  in  that 
the  young  are  nourished  by  milk  produced  for  this  purpose  in  the  breasts 
of  the  mother;  when  he  understands  this,  he  can  comprehend  how  such 
diverse  forms  as  the  whale,  the  cow,  the  bat,  and  human  beings  are  akin.

THE  COTTON-TAIL  RABBIT 


Teacher's  Story 


“ The  Bunnies  are  a feeble  folk  whose  weakness  is  their  strength. 

To  shun  a gun  a Bun  will  run  to  almost  any  length.” — Oliver  Herford. 


IS  well  for  Molly  Cotton-tail  and  her  family  that  they 
have  learned  to  shun  more  than  guns  for  almost  every 
predatory  animal  and  bird  makes  a dinner  of  them  on 
every  possible  occasion.  But  despite  these  enemies, 
moreover,  with  the  addition  of  guns,  men  and  dogs, 
the  cotton-tail  lives  and  flourishes  in  our  midst.  A 
“Molly”  raised  two  families  last  year  in  a briar-patch 
back  of  our  garden  on  the  Cornell  Campus,  where  dogs 
of  many  breeds  abound ; and  after  each  fresh  fall  of 
snow  this  winter  we  have  been  able  to  trace  our 
bunny  neighbors  in  their  night  wanderings  around 
the  house,  beneath  the  spruces  and  in  the  orchard. 
The  track  consists  of  two  long  splashes,  paired, 
and  between  and  a little  behind  them,  two  smaller  ones;  the  rabbit 
uses  its  front  feet  as  a boy  uses  a vaulting  pole  and  lands  both 
hind  feet  on  each  side  and  ahead  of  them;  owing  to  the  fact  that  the 
bottoms  of  the  feet  are  hairy  the  print  is  not  clear-cut.  When  the  rabbit 
is  not  in  a hurry  it  has  a peculiar  lope,  but  when  frightened  it  makes  long 
jumps.  The  cotton-tails  are  night  wanderers  and  usually  remain  hidden 
during  the  day.  In  summer,  they  feed  on  clover  or  grass  or  other  juicy 
herbs  and  show  a fondness  for  sweet  apples  and  fresh  cabbage;  in  our 


214 


Handbook  of  N atur e -Study 


garden  last  summer  Molly  was  very  considerate.  She  carefully  pulled 
all  the  grass  out  of  the  garden-cress  bed,  leaving  the  salad  for  our  enjoy- 
ment. In  winter,  the  long,  gnawing  teeth  of  the  cotton-tail  are  some- 
times used  to  the  damage  of  fruit  trees  and  nursery  stock  since  the  rabbits 
are  obliged  to  feed  upon  bark  in  order  to  keep  alive. 

The  long,  strong  hind  legs  and  the  long  ears  tell  the  whole  bunny 
story.  Ears  to  hear  the  approach  of  the  enemy,  and  legs  to  propel  the 
listener  by  long  jumps  to  a safe  retreat.  The  attitude  of  the  ears  is  a good 
indication  of  the  bunny’s  state  of  mind;  if  they  are  set  back  to  back  and 
directed  backward,  they  indicate  placidity,  but  a placidity  that  is  always 
on  guard ; if  lifted  straight  up  they  signify  attention  and  anxiety ; if  one 
is  bent  forward  and  the  other  backward  the  meaning  is:  “Now  just 

where  did  that  sound  come  from?”  When  running  or  when  resting  in  the 
form,  the  ears  are  laid  back  along  the  neck.  When  the  cotton-tail  stands 
up  on  its  haunches  with  both  ears  erect,  it  looks  very  tall  indeed. 

Not  only  are  the  ears  always  alert,  but  also  the  nose;  the  nostrils  are 
partially  covered  and  in  order  to  be  always  sure  of  getting  every  Scent 
they  wabble  constantly,  the  split  upper  lip  aiding  in  this  performance; 
when  the  rabbit  is  trying  to  get  a scent  it  moves  its  head  up  and  down  in  a 
sagacious,  apprehensive  manner. 

The  rabbit  has  an  upper  and  lower  pair  of  incisors  like  other  rodents, 
but  on  the  upper  jaw  there  is  a short  incisor  on  each  side  of  the  large 
teeth ; these  are  of  no  use  now  but  are  inherited  from  some  ancestor  which 
found  them  useful.  There  are  at  the  back  of  each  side  of  the  upper  jaw 
six  grinding  teeth,  and  five  on  each  side  of  the  lower  jaw.  The  split 
upper  lip  allows  the  free  use  of  the  upper  incisors.  The  incisors  are  not 
only  used  for  taking  the  bark  from  trees,  but  also  for  cutting  grass  and 
other  food.  The  rabbit  has  a funny  way  of  taking  a stem  of  grass  or 
clover  at  the  end  and  with  much  wabbling  of  lips,  finally  taking  it  in, 
meanwhile  chewing  it  with  a sidewise  motion  of  the  jaws.  The  rabbits’ 
whiskers  are  valuable  as  feelers,  and  are  always  kept  on  the  qui  vive  for 
impressions ; when  two  cotton-tails  meet  each  other  amicably,  they  rub 
whiskers  together.  The  eyes  are  large  and  dark  and  placed  on  the  bulge 
at  the  side  of  the  head,  so  as  to  command  the  view  both  ways.  Probably 
a cotton-tail  winks,  but  I never  caught  one  in  the  act. 

The  strong  hind  legs  of  the  rabbit  enable  it  to  make  prodigious  jumps, 
of  eight  feet  or  more;  this  is  a valuable  asset  to  an  animal  that  escapes 
its  enemies  by  running.  The  front  feet  are  short  and  cannot  be  turned 
inward  like  those  of  the  squirrel,  to  hold  food.  There  are  five  toes  on  the 
front  feet,  and  four  on  the  hind  feet ; the  hair  on  the  bottom  of  the  feet  is 
a protection,  much  needed  by  an  animal  which  sits  for  long  periods  upon 
the  snow.  When  sleeping,  the  front  paws  are  folded  under  and  the  rabbit 
rests  on  the  entire  hind  foot,  with  the  knee  bent,  ready  for  a spring  at  the 
slightest  alarm ; when  awake,  it  rests  on  the  hind  feet  and  front  toes;  and 
when  it  wishes  to  see  if  the  coast  is  clear,  it  rises  on  its  hind  feet,  with 
front  paws  drooping. 

The  cotton-tail  has  a color  well  calculated  to  protect  it  from  observa- 
tion ; it  is  brownish-gray  on  the  back  and  a little  lighter  along  the  sides, 
grayish  under  the  chin  and  whitish  below;  the  ears  are  edged  with  black, 
and  the  tail  when  raised  shows  a large,  white  fluff  at  the  rear.  The  general 
color  of  the  rabbit  fits  in  with  natural  surroundings;  since  the  cotton-tail 
often  escapes  its  enemies  by  “freezing,”  this  color  makes  the  scheme  work

well.  I once  saw  a marsh  hare,  on  a stone  in  a brook,  freezing  most  suc- 
cessfully. I could  hardly  believe  that  a living  thing  could  seem  so 
much  like  a stone;  only  its  bright  eyes  revealed  it  to  us. 

The  rabbit  cleans  itself  in  amusing  ways. 

It  shakes  its  feet,  one  at  a time,  with  great 
vigor  and  rapidity  to  get  off  the  dirt  and  then 
licks  them  clean.  It  washes  its  face  with 
both  front  paws  at  once.  It  scratches  its  ear 
with  the  hind  foot,  and  pushes  it  forward  so 
that  it  can  be  licked;  it  takes  hold  of  its  fur 
with  its  front  feet  to  pull  it  around  within 
reach  of  the  tongue. 

The  cotton-tail  does  not  dig  a burrow, 
but  sometimes  occupies  the  deserted  burrow 
of  a woodchuck  or  skunk.  Its  nest  is  called  a “form,”  which  simply 
means  a place  beneath  a cover  of  grass  or  briars,  where  the  grass  is  beaten 
down  or  eaten  out  for  a space  large  enough  for  the  animal  to  sit.  The 
mother  makes  a soft  bed  for  the  young,  using  grass  and  her  own  hair  for 
the  purpose;  and  she  constructs  a coarse  felted  coverlet,  under  which  she 
tucks  her  babies  with  care,  every  time  she  leaves  them.  Young  rabbits 
are  blind  at  first,  but  when  about  three  weeks  old,  are  sufficiently  grown 
to  run  quite  rapidly.  Although  there  may  be  five  or  six  in  a litter,  yet 
there  are  so  many  enemies  that  only  a few  escape. 

Fox,  mink,  weasel,  hawk,  owl  and  snake  all  relish  the  young  cotton- 
tail if  they  can  get  it.  Nothing  but  its  runways  through  the  briars  can 
save  it.  These  roads  wind  in  and  out  and  across,  twisting  and  turning 
perplexingly ; they  are  made  by  cutting  off  the  grass  stems,  and  are  just 
wide  enough  for  the  rabbit’s  body.  However,  a rabbit  has  weapons  and 
can  fight  if  necessary;  it  leaps  over  its  enemy,  kicking  it  on  the  back 
fiercely  with  its  great  hind  feet.  Mr.  Seton  tells  of  this  way  of  conquering 
the  black  snake,  and  Mr.  Sharp  saw  a cat  completely  vanquished  by  the 
same  method.  The  rabbit  can  also  bite,  and  when  two  males  are  fighting, 
they  bite  each  other  savagely.  Mr.  E.  W.  Cleeves  told  me  of  a Belgian 
doe  which  showed  her  enmity  to  cats  in  a peculiar  way.  She  would  run 
after  any  cats  that  came  in  sight,  butting  them  like  a billy-goat.  The  cats 
soon  learned  her  tricks,  and  would  climb  a tree  as  soon  as  they  caught 
sight  of  her.  The  rabbit’s  sound  of  defiance,  is  thumping  the  ground 
with  the  strong  hind  foot.  Some  have  declared  that  the  front  feet  are 
used  also  for  stamping;  although  I have  heard  this  indignant  thumping 
more  than  once,  I could  not  see  the  process.  The  cotton-tail  is  a hare, 
while  the  common  domestic  rabbit  is  a true  rabbiti  The  two  differ 
chiefly  in  the  habits  of  nesting;  the  hares  rest  and  nest  in  forms,  while 
the  rabbit  makes  burrows,  digging  rapidly  with  the  front  feet. 

Not  the  least  of  tributes  to  the  rabbit’s  sagacity,  are  the  negro  folk- 
stories  told  by  Uncle  Remus,  wherein  Bre’r  Rabbit*  although  often  in 
trouble,  is  really  the  most  clever  of  all  the  animals.  I have  often  thought

when  I have  seen  the  tactics  which  rabbits  have  adopted  to  escape  dogs, 
that  we  in  the  North  have  under-rated  the  cleverness  of  this  timid  animal. 
In  one  instance  at  least  that  came  under  our  observation,  a cotton-tail 
led  a dog  to  the  verge  of  a precipice,  then  doubled  back  to  safety,  while 
the  dog  went  over,  landing  on  the  rocks  nearly  three  hundred  feet  below. 

LESSON  LIII 
The  Cotton-tail  Rabbit 

Leading  thought — 
The  cotton-tail  thrives 
amid  civilization ; its 
color  protects  it  from 
sight ; its  long  ears 
give  it  warning  of  the 
approach  of  danger; 
and  its  long  legs  en- 
able it  to  run  by  swift, 
long  leaps.  It  feeds 
upon  grasses,  clover, 
vegetables  and  other 
herbs. 

, _ , ...  Method — This  study 

Belgian  hares  and  Dutch  rabbit.  may  be  begun  jn  thg 

winter,  when  the  rabbit  tracks  can  be  observed  and  the  haunts  of  the 
cotton-tail  discovered.  If  caught  in  a box  trap,  the  cotton-tail  will  be- 
come tame  if  properly  fed  and  cared  for,  and  may  thus  be  studied  at 
close  range.  The  cage  I have  used  for  rabbits  as  thus  caught,  is  made 
of  wire  screen,  nailed  to  a frame,  making  a wire-covered  box,  two  feet 
high  and  two  or  three  feet  square,  with  a door  at  one  side  and  no  bot- 
tom. It  should  be  placed  upon  oil-cloth  or  linoleum,  and  thus  may  be 
moved  to  another  carpet  when  the  floor  needs  cleaning.  If  it  is  im- 
possible to  study  the  cotton-tail,  the  domestic  rabbit  may  be  used 
instead. 

Observations — i . What  sort  of  tracks  does  the  cotton-tail  make  in  the 
snow?  Describe  and  sketch  them.  Where  do  you  find  these  tracks? 
How  do  you  know  which  way  the  rabbit  was  going?  Follow  the  track 
and  see  if  you  can  find  where  the  rabbit  went.  When  were  these  tracks 
made,  by  night  or  by  day?  What  does  the  rabbit  do  during  the  day? 
What  does  it  find  to  eat  during  the  winter?  How  are  its  feet  protected 
so  that  they  do  not  freeze  in  the  snow? 

2.  What  are  the  two  most  noticeable  peculiarities  of  the  rabbit? 
Of  what  use  are  such  large  ears  ? How  are  the  ears  held  when  the  rabbit 
is  resting?  When  startled?  When  not  quite  certain  about  the  direction 
of  the  noise?  Explain  the  reasons  for  these  attitudes.  When  the  rabbit 
wishes  to  make  an  observation  to  see  if  there  is  danger  coming,  what  does 
it  do?  How  does  it  hold  its  ears  then ? How  are  the  ears  held  when  the 
animal  is  running  ? 

3 . Do  you  think  the  rabbit  has  a keen  sense  of  smell  ? Describe  the 
movements  of  the  nostrils  and  explain  the  reason.  How  does  it  move  its 
head  to  be  sure  of  getting  the  scent?

4.  What  peculiarity  is  there  in  the  upper  lip  ? How  would  this  be  an 
aid  to  the  rabbit  when  gnawing  ? Describe  the  teeth ; how  do  these  differ 
from  those  of  the  mouse  or  squirrel  ? Of  what  advantage  are  the  gnawing 
teeth  to  the  rabbit  ? How  does  it  eat  a stem  of  grass  ? Note  the  rabbit’s 
whiskers.  What  do  you  think  they  are  used  for? 

5.  Describe  the  eyes.  How  are  they  placed  so  that  the  rabbit  can 
see  forward  and  backward?  Do  you  think  that  it  sleeps  with  its  eyes 
open?  Does  it  wink? 

6.  Why  is  it  advantageous  to  the  rabbit  to  have  such  long,  strong, 
hindlegs?  Compare  them  in  size  with  the  front  legs.  Compare  the  front 
and  hind  feet.  How  many  toes  on  each?  How  are  the  bottoms  of  the 
feet  protected?  Are  the  front  feet  ever  used  for  holding  food  like  the 
squirrel’s?  In  what  position  are  the  legs  when  the  rabbit  is  resting? 
When  it  is  standing?  When  lifted  up  for  observation? 

7.  How  does  the  cotton-tail  escape  being  seen?  Describe  its  coat. 
Of  what  use  is  the  white  fluff  beneath  the  tail?  Have  you  ever  seen  a 
wild  rabbit  “freeze”  ? What  is  meant  by  freezing  and  what  is  the  use  of  it  ? 

8.  In  making  its  toilet  how  does  the  rabbit  clean  its  face,  ears,  feet, 
and  fur? 

9.  What  do  the  cotton-tails  feed  upon  during  the  summer?  During 
the  winter?  Do  they  ever  do  much  damage? 

10.  Describe  the  cotton-tail’s  nest.  What  is  it  called?  Does  it  ever 
burrow  in  the  ground  ? Does  it  ever  use  a second-hand  burrow  ? Describe 
the  nest  made  for  the  young  by  the  mother.  Of  what  is  the  bed  com- 
posed? Of  what  is  the  coverlet  made?  What  is  the  special  use  of  the 
coverlet?  How  do  the  young  cotton-tails  look?  How  old  are  they 
before  they  are  able  to  take  care  of  themselves? 

11.  What  are  the  cotton-tail’s  enemies?  How  does  it  escape  them? 
Have  you  ever  seen  the  rabbit  roads  in  a briar  patch  ? Do  you  think  that 
a dog  or  fox  could  follow  them  ? Do  rabbits  ever  fight  their  enemies  ? If 
so,  how?  How  do  they  show  anger?  Do  they  stamp  with  the  front  or 
the  hind  foot  ? 

12.  Tell  how  the  cotton-tail  differs  in  looks  and  habits  from  the 
common  tame  rabbit.  How  do  the  latter  dig  their  burrows?  How 
many  breeds  of  tame  rabbits  do  you  know? 

13.  Write  or  tell  stories  on  the  following  topics:  “A  Cotton-tail’s 

Story  of  its  Own  Life  Until  it  is  a Year  Old;”  “The  Jack-rabbit  of  the 
West;”  “The  Habits  of  the  White  Rabbit  or  Varying  Hare;”  “The  Rab- 
bit in  Uncle  Remus’  Tales.”

THE  MUSKRAT 


Teacher's  Story 

“ Having  finished  this  first  course  of  big-neck  clams,  they  were  joined  by  a third 
muskrat,  and,  together,  they  filed  over  the  bank  and  down  into  the  meadow.  Shortly 
two  of  them  returned  with  great  mouthfuls  of  the  mud-bleached  ends  of  calamus-blades. 
Then  followed  the  washing. 

They  dropped  their  loads  upon  the  plank,  took  up  the  stalks,  pulled  the  blades  apart, 
and  soused  them  up  and  down  in  the  water,  rubbing  them  with  their  paws  until  they 
were  as  clean  and  white  as  the  whitest  celery  one  ever  ate.  What  a dainty  picture ! 
Two  little  brown  creatures,  humped  on  the  edge  of  a plank,  washing  calamus  in  moonlit 
water!" — Dallas  Lore  Sharp. 


RACKING  is  a part  of  every  boy’s  education  who 
aspires  to  a knowledge  of  wood  lore ; and  a boy  with 
this  accomplishment  is  sure  to  be  looked  upon 
with  great  admiration  by  other  boys,  less  skilled  in 
the  interpretation  of  that  writing  made  by  small  feet, 
on  the  soft  snow  or  on  the  mud  of  stream  margins. 
To  such  a boy,  the  track  of  the  muskrat  is  well 
known,  and  very  easily  recognized. 

The  muskrat  is  essentially  a water  animal,  and  therefore  its  tracks  are 
to  be  looked  for  along  the  edges  of  ponds,  streams  or  in  marshes.  Whether 
the  tracks  are  made  by  walking  or  jumping,  depends  upon  the  depth  of 
the  snow  or  mud;  if  it  is  deep,  the  animal  jumps,  but  in  shallow  snow  or 
mud,  it  simply  runs  along.  The  tracks  show  the  front  feet  to  be  smaller

than  the  hind  ones.  The  muskrat  track  is,  however,  characterized  by  the 
tail  imprint.  When  the  creature  jumps  through  the  snow,  the  mark  of 
the  tail  follows  the  paired  imprints  of  the  feet;  when  it  walks,  there  is  a 
continuous  line  made  by  this  strong,  naked  tail.  This  distinguishes  the 
track  of  the  muskrat  from  that  of  the  mink,  as  the  bushy  tail  of  the  latter 
does  not  make  so  distinct  a mark.  Measuring  the  track,  is  simply  a 
device  for  making  the  pupils  note  its  size  and  shape  more  carefully.  The 
tracks  may  be  looked  for  during  the  thaws  of  March  or  February,  when 
the  muskrats  come  out  of  the  water  to  seek  food. 

In  appearance  the  muskrat  is  peculiar.  The  body  is  usually  about  a 
foot  in  length  and  the  tail  about  eight  inches.  The  body  is  stout  and 
thickset,  the  head  is  rounded  and  looks  like  that  of  a giant  meadow 
mouse;  the  eyes  are  black  and  shining;  the  ears  are  short  and  close  to  the 
head;  the  teethx  like  those  of  other  rodents,  consist  of  a pair  of  front 
teeth  on  each  jaw,  then  a long,  bare  space  and  four  grinders  on  each  side. 
There  are  long  sensitive  hairs  about  the  nose  and  mouth,  like  the  whiskers 
of  mice. 

The  muskrat’s  hind  legs  are  much  larger  and  stronger  than  the  front 
ones;  and  too,  the  hind  feet  are  much  longer  than  the  front  feet  and  have 
a web  between  the  toes;  there  are  also  stiff  hairs  which  fill  the  space 
between  the  toes,  outside  the  web,  thus  making  this  large  hind  foot  an 
excellent  swimming  organ.  The  front  toes  are  not  webbed  and  are  used 
for  digging.  The  claws  are  long,  stout  and  sharp.  The  tail  is  long,  stout 
and  flattened  at  the  sides;  it  has  little  or  no  fur  upon  it  but  is  covered 
with  scales ; it  is  used  as  a scull  and  also  as  a rudder  when  the  muskrat  is 
swimming. 

The  muskrat’s  outer  coat  consists  of  long,  rather  coarse  hairs;  its 
under  coat  is  of  fur,  very  thick  and  fine,  and  although  short,  it  forms  a 
waterproof  protection  for  the  body  of  the  animal.  In  color,  the  fur  is 
dark  brown  above  with  a darker  streak  along  the  middle  of  the  back; 
beneath,  the  body  is  grayish  changing  to  whitish  on  the  throat  and  lips, 
with  a brown  spot  on  the  chin.  In  preparing  the  pelts  for  commercial 
use,  the  long  hairs  are  plucked  out  leaving  the  soft,  fine  under  coat,  which 
is  dyed  and  sold  under  the  name  of  “electric  seal.” 

The  muskrat  is  far  better  fitted  by  form,  for  life  in  the  water  than  upon 
the  land.  Since  it  is  heavy-bodied  and  short-legged,  it  cannot  run  rapidly 
but  its  strong,  webbed  hind  feet  are  most  efficient  oars,  and  it  swims 
rapidly  and  easily;  for  rudder  and  propeller  the  strong,  flattened  tail 
serves  admirably,  while  the  fine  fur  next  the  body  is  so  perfectly  water- 
proof that,  however  much  the  muskrat  swims  or  dives,  it  is  never  wet. 
It  is  a skillful  diver  and  can  stay  under  water  for  several  minutes ; when 
swimming,  its  nose  and  sometimes  the  head  and  the  tip  of  the  tail  appear 
on  the  surface  of  the  water. 

The  food  of  muskrats  is  largely  roots,  especially  those  of  the  sweet  flag 
and  the  yellow  lily.  They  also  feed  on  other  aquatic  plants  and  are  fond 
of  the  fresh-water  shell-fish.  Mr.  Sharp  tells  us,  in  one  of  his  delightful 
stories,  how  the  muskrats  wash  their  food  by  sousing  it  up  and  down  in 
water  many  times  before  eating  it.  Often,  a muskrat  chooses  some 
special  place  upon  the  shore  which  it  uses  for  a dining-room,  bringing 
there  and  eating  pieces  of  lily  root  or  fresh-water  clams,  and  leaving  the 
debris  to  show  where  it  habitually  dines.  It  does  most  of  its  hunting  for  food 
at  night,  although  sometimes  it  may  be  seen  thus  employed  during  the  day.

Handbook  of  Nature-Study 


The  winter  lodge  of  the  muskrat  is  a most  interesting  structure.  A 
foundation  of  tussocks  of  rushes,  in  a stream  or  shallow  pond,  is  built 
upon  with  reeds  plastered  with  mud,  making  a rather  regular  dome  which 
may  be  nearly  two  or  three  feet  high ; or,  if  many-chambered,  it  may  be  a 
grand  affair  of  four  or  five  feet  elevation ; but  it  always  looks  so  much  like 
a natural  hummock  that  the  eye  of  the  uninitiated  never  regards  it  as  a 
habitation.  Always  beneath  this  dome  and  above  the  water  line,  is  a 
snug,  covered  chamber  carpeted  with  a soft  bed  of  leaves  and  moss, 
which  has  a passage  leading  down  into  the  water  below,  and  also  has  an 
air-hole  for  ventilation.  In  these  cabins,  closely  cuddled  together,  three 
or  four  in  a chamber,  the  muskrats  pass  the  winter.  After  the  pond  is 
frozen  they  are  safe  from  their  enemies  and  are  always  able  to  go  down 
into  the  water  and  feed  upon  the  roots  of  water  plants.  These  cabins  are 
sometimes  built  in  the  low,  drooping  branches  of  willows  or  on  other 
objects. 


Whether  the  muskrat  builds  itself  a winter  lodge  or  not,  depends  upon 
the  nature  of  the  shore  which  it  inhabits;  if  it  is  a place  particularly  fitted 
for  burrows,  then  a burrow  will  be  used  as  a winter  retreat;  but  if  the 
banks  are  shallow,  the  muskrats  unite  in  building  cabins.  The  main 
entrance  to  the  muskrat  burrow  is  always  below  the  surface  of  the  water, 
the  burrow  slanting  upward  and  leading  to  a nest  well  lined,  which  is 
above  the  reach  of  high  water;  there  is  always  an  air  hole  above,  for 
ventilating  this  nest,  and  there  is  also  often  a passage,  with  a hidden 
entrance,  leading  out  to  dry  land. 

The  flesh  of  the  muskrat  is  delicious,  and  therefore  the  animal  has 
many  enemies;  foxes,  weasels,  dogs,  minks  and  also  hawks  and  owls  prey 
upon  it.  It  escapes  the  sight  of  its  enemies  as  does  the  mouse,  by  having 
the  color  of  its  fur  not  noticeable;  when  discovered,  it  escapes  its  enemies 
by  swimming,  although  when  cornered,  it  is  courageous  and  fights  fiercely, 
using  its  strong  incisors  as  weapons.  In  winter,  it  dwells  in  safety  when 
the  friendly  ice  protects  it  from  all  its  enemies  except  the  mink ; but  it  is 
exposed  to  great  danger  when  the  streams  break  up  in  spring,  for  it  is  then 
often  driven  from  its  cabin  by  floods,  and  preyed  upon  while  thus  help- 
lessly exposed.  The  muskrat  gives  warning  of  daneer  to  its  fellows  by 
splashing  the  water  with  its  strong  tail

lessly for  its  pelt. 

The  little  musk- 
rats are  born  in 
April  and  there  are 
usually  from  six  to 
eight  in  a litter. 
Another  litter  may 
be  produced  in 
June  or  July  and 
a third  in  August 
or  September.  It  is 
only  thus,  by  rear- 
ing large  families 
often,  that  the 
muskrats  are  able 
to  hold  their  own 
against  the  hunters 
and  trappers  and 
their  natural  ene- 
mies.

LESSON  LIV 


The  Muskrat 

Leading  thought — The  muskrat,  while  a true  rodent,  is  fitted  for  life 
in  the  water  more  than  for  life  upon  the  land.  Its  hind  feet  are  webbed 
for  use  as  oars  and  its  tail  is  used  as  a rudder.  It  builds  lodges  of  mud, 
cat-tails  and  rushes  in  which  it  spends  the  winter. 

Method — It  might  be  well  to  begin  this  work  by  asking  for  observations 
on  the  tracks  of  the  muskrat  which  may  be  found  about  the  edges  of 
almost  any  creek,  pond  or  marsh.  If  there  are  muskrat  lodges  in  the 
region  they  should  be  visited  and  described.  For  studying  the  muskrat’s 
form  a live  muskrat  in  captivity  is  almost  necessary.  If  one  is  trapped

with  a “figure  iour”  it  will  not  be  injured  and  it  may  be  made  more  or 
less  tame  by  feeding  it  with  sweet  apples,  carrots  and  parsnips.  The 
pupils  can  thus  study  it  at  leisure  although  they  should  not  be  allowed  to 
handle  the  creature  as  it  inflicts  very  severe  wounds  and  is  never  willing 
to  be  handled.  If  a live  muskrat  cannot  be  obtained  perhaps  some  hunter 
in  the  neighborhood  will  supply  a dead  one  for  this  observation  lesson. 

While  studying  the  muskrat  the  children  should  read  all  the  stories  of 
beavers  which  are  available  as  the  two  animals  are  very  much  alike  in 
their  habits. 

Observations — i.  In  what  locality  have  you  discovered  the  tracks  of 
the  muskrat?  Describe  its  general  appearance.  Measure  the  muskrat’s 
track  as  follows : (a)  Width  and  length  of  the  print  of  one  foot ; (b)  the 

width  between  the  prints  of  the  two  hind  feet ; (c)  the  length  between  the 
prints  made  by  the  hind  feet  in  several  successive  steps  or  jumps. 

2.  Was  the  muskrat’s  track  made  when  the  animal  was  jumping  or 
walking?  Can  you  see  in  it  a difference  in  the  size  of  the  front  and  hind 
feet?  Judging  from  the  track,  where  do  you  think  the  muskrat  came 
from?  What  do  you  think  it  was  hunting  for? 

3.  What  mark  does  the  tail  make  in  the  snow  or  mud?  Judging  by 
its  imprint,  should  you  think  the  muskrat’s  tail  was  long  or  short,  bare  or 
brushy,  slender  or  strong? 

4.  How  long  is  the  largest  muskrat  you  ever  saw?  How  much  of  the 
whole  length  is  tail?  Is  the  general  shape  of  the  body  short  and  heavy 
or  long  and  slender? 

5.  Describe  the  muskrat’s  eyes,  ears  and  teeth.  For  what  are  the 
teeth  especially  fitted  ? Has  the  muskrat  whiskers  like  mice  and  rats  ? 

6.  Compare  the  front  and  hind  legs  as  to  size  and  shape.  Is  there  a 
web  between  the  toes  of  the  hind  feet?  What  does  this  indicate?  Do 
you  think  that  the  muskrat  is  a good  swimmer  ? 

7.  Describe  the  muskrat  fur.  Compare  the  outer  and  under  coat. 
What  is  its  color  above  and  below?  What  is  the  name  of  muskrat  fur  in 
the  shops? 

8.  Describe  the  tail.  What  is  its  covering?  How  is  it  flattened? 
What  do  you  think  this  strong,  flattened  tail  is  used  for? 

9.  Do  you  think  the  muskrat  is  better  fitted  to  live  in  the  water  than 
on  land  ? How  is  it  fitted  to  live  in  the  water  in  the  following  particulars : 
Feet?  Tail?  Fur? 

10.  How  much  of  the  muskrat  can  you  see  when  it  is  swimming? 
How  long  can  it  stay  under  water  when  diving  ? 

11.  What  is  the  food  of  the  muskrat ? Where  does  it  find  it?  How 
does  it  prepare  the  food  for  eating?  Does  it  seek  its  food  during  the  night 
or  day?  Have  you  ever  observed  the  muskrat’s  dining  room?  If  so, 
describe  it. 

12.  Describe  the  structure  of  the  muskrat’s  winter  lodge,  or  cabin, 

in  the  following  particulars : Its  size.  Where  built  ? Of  what  material  ? 

How  many  rooms  in  it  ? Are  these  rooms  above  or  below  the  water  level  ? 
Of  what  is  the  bed  made?  How  is  the  nest  ventilated?  How  is  it 
arranged  so  that  the  entrance  is  not  closed  by  the  ice?  Is  such  a home 
built  by  one  or  more  muskrats?  How  many  live  within  it?  Do  the 
muskrats  always  build  these  winter  cabins?  What  is  the  character  of 
the  shores  where  they  are  built  ? 


Mammal  Study 


223 


13.  Describe  the  muskrat’s  burrow  in  the  bank  in  the  following 

particulars : Is  the  entrance  above  or  below  water  ? Where  and  how  is 

the  nest  made  ? Is  it  ventilated  ? Does  it  have  a back  door  leading  out 
upon  the  land  ? 

14.  What  are  the  muskrat’s  enemies?  How  does  it  escape  them? 
How  does  it  fight?  Is  it  a courageous  animal?  How  does  the  muskrat 
give  warning  to  its  fellows  when  it  perceives  danger?  At  what  time  of 
year  is  it  comparatively  safe?  At  what  time  is  it  exposed  to  greatest 
danger? 

15.  Why  is  this  animal  called  muskrat?  Compare  the  habits  of 
muskrats  with  those  of  beaver  and  write  an  English  theme  upon  the 
similarity  of  the  two. 

16.  At  what  time  of  year  do  you  find  the  young  muskrats?  How 
many  in  a litter  ? 

17.  Read  Farmers’  Bulletin  No.  396  of  the  U.  S.  Dept,  of  Agriculture 
and  write  an  English  theme  on  the  destructive  habits  of  muskrats  and  the 
economic  uses  of  these  animals.

The  white-footed,  or  deer,  mouse.

Handbook  of  N atur  e-Study 


The  house  mouse  feeds  upon  almost  anything  which  people  like  to  eat. 


THE  HOUSE  MOUSE 
Teacher's  Story 

Somewhere  in  the  darkness  a clock  strikes  two; 

And  there  is  no  sound  in  the  sad  old  house , 

But  the  long  veranda  dripping  with  dew , 

And  in  the  wainscot — a mouse. — Bret  Harte. 

ERE  mouse-gray  a less  inconspicuous  color,  there 
would  be  fewer  mice;  when  a mouse  is  running 
along  the  floor,  it  is  hardly  discernible,  it  looks  so 
like  a flitting  shadow;  if  it  were  black  or  white  or 
any  other  color,  it  would  be  more  often  seen  and 
destroyed.  Undoubtedly,  it  is  owing  to  the  fact 
that  its  soft  fur  has  this  shadowy  color,  that  this 
species  has  been  able  to  spread  over  the  world. 

At  first  glance  one  wonders  what  possible  use  a mouse  can  make  of  a 
tail  which  is  as  long  as  its  body,  but  a little  careful  observation  will 
reveal  the  secret.  The  tail  is  covered  with  transverse  ridges  and  is  bare 
save  for  sparse  hairs,  except  toward  the  tip.  Dr.  Ida  Reveley  first  called 
my  attention  to  the  fact  that  the  house  mouse  uses  its  tail  in  climbing.  I 
verified  this  interesting  observation,  and  found  that  my  mouse  used  the 
tail  for  aid  when  climbing  a string.  He  would  go  up  the  string,  hand  over 
hand,  like  a sailor,  then  in  trying  to  stretch  to  the  edge  of  his  jar,  he 
invariably  wound  his  tail  about  the  string  two  or  three  times,  and  hanging 
to  the  string  with  the  hind  feet  and  tail,  would  reach  far  out  with  his  head 
and  front  feet.  Also,  when  clinging  to  the  edge  of  the  cover  of  the  jar,  he 
invariably  used  his  tail  as  a brace  against  the  side  of  the  glass,  so  that  it 
pressed  hard  for  more  than  half  its  length.  Undoubtedly  the  tail  is  of 
great  service  when  climbing  up  the  sides  of  walls. 


Mammal  Study 


225 


The  tail  is  also  of  some  use,  when  the  mouse  jumps  directly  upwards. 
The  hind  legs  are  very  much  longer  and  stronger  than  the  front  legs.  The 
hind  feet  are  also  much  longer  and  larger  than  the  front  feet ; and  although 
the  mouse,  when  it  makes  its  remarkable  jumps,  depends  upon  its  strong 
hind  legs,  I am  sure  that  often  the  tail  is  used  as  a brace  to  guide  and 
assist  the  leap.  The  feet  are  free  from  hairs  but  are  downy;  the  hind 
foot  has  three  front  toes,  a long  toe  behind  on  the  outside  and  a short  one 
on  the  inside.  The  claws  are  fairly  long  and  very  sharp  so  that  they  are 
able  to  cling  to  almost  anything  but  glass.  When  exploring,  a mouse 
stands  on  its  hind  feet,  folding  its  little  front  paws  under  its  chin  while  it 
reaches  up  ready  to  catch  anything  in  sight;  it  can  stretch  up  to  an 
amazing  height.  It  feeds  upon  almost  anything  which  people  like  to  eat 
and,  when  eating,  holds  its  food  in  its  front  paws  like  a squirrel. 

The  thin,  velvety  ears  are  flaring  cornucopias  for  taking  in  sound;  the 
large,  rounded  outer  ear  can  be  moved  forward  or  back  to  test  the  direc- 
tion of  the  noise.  The  eyes  are  like  shining,  black  beads;  and  if  a 
mouse  can  wink,  it  does  it  so  rapidly  as  not  to  be  discernible.  The  nose 
is  long,  inquisitive,  and  always  sniffing  for  hew  impressions.  The 
whiskers  are  delicate  and  probably  sensitive.  The  mouth  is  furnished 
with  two  long,  curved  gnawing  teeth  at  the  front  of  each  jaw,  then  a bare 
space,  and  four  grinding  teeth  on  each  side,  above  and  below,  like  the 
teeth  of  woodchucks  and  other  rodents.  The  gnawing  teeth  are  very 
strong  and  enable  the  mouse  to  gnaw  through  board  partitions  and  other 
obstacles. 

The  energy  with  which  the  mouse  cleans  itself  is  inspiring  to  behold. 
It  nibbles  its  fur  and  licks  it  with  fervor,  reaching  around  so  as  to  get  at  it 
from  behind,  and  tak- 
ing hold  with  its  little 
hands  to  hold  firm 
while  it  cleans.  When 
washing  its  face  and 
head,  it  uses  both 
front  feet,  licking 
them  clean  and  rub- 
bing them  both  simul- 
taneously from  behind 
the  ears  down  over 
the  face.  It  takes  its 
hind  foot  in  both  front 
feet  and  nibbles  and 
licks  it.  It  scratches 
the  back  of  its  head 
with  its  hind  foot. 

Young  mice  are 
small,  downy,  pink 
and  blind  when  born. 

The  mother  makes  for 
them  a nice,  soft  nest 
of  pieces  of  cloth, 
paper,  grass,  or  what- 
ever is  at  hand;  the 

nest  is  round  like  Young  mice,  blind,  pink  and  hairless.

a ball  and  at  its  center  is  nestled  the  family.  Mice  living  in  houses, 
have  runways  between  the  plaster  and  the  outside,  or  between  ceiling 
and  floor.  In  winter  they  live  on  what  food  they  can  find,  and  upon  flies 
or  other  insects  hibernating  in  our  houses.  The  house  mice  sometimes 
live  under  stacks  of  com  or  grain  in  the  fields,  but  usually  confine  them- 
selves to  houses  or  barns.  They  are  thirsty  little  fellows  and  they  like  to 
make  their  nests  within  easy  reach  of  water.  Our  house  mice  came  from 
ancestors  which  lived  in  Asia  originally;  they  have  always  been  great 
travelers  and  they  have  followed  men  wherever  they  have  gone,  over  the 
world.  They  came  to  America  on  ships  with  the  first  explorers  and  the 
Pilgrim  fathers.  They  now  travel  back  and  forth,  crossing  the  ocean  in 
ships  of  all  sorts.  They  also  travel  across  the  continent  on  trains. 
Wherever  our  food  is  carried  they  go ; and  the  mouse,  which  you  see  in 
your  room  one  day,  may  be  a thousand  miles  away  within  a week.  They 
are  clever  creatures,  and  learn  quickly  to  connect  cause  and  effect.  For 
two  years,  I was  in  an  office  in  Washington,  and  as  soon  as  the  bell  rang 
for  noon,  the  mice  would  appear  instantly,  hunting  waste-baskets  for 
scraps  of  lunch.  They  had  learned  to  connect  the  sound  of  the  bell 
with  food. 

Of  all  our  wild  mice,  the  white-footed  or  deer  mouse  is  the  most 
interesting  and  attractive.  It  is  found  almost  exclusively  in  woods  and  is 
quite  different  in  appearance  from  other  mice.  Its  ears  are  very  large; 
its  fur  is  fine  and  beautiful  and  a most  delicate  gray  color.  It  is  white 
beneath  the  head  and  under  the  sides  of  the  body.  The  feet  are  pinkish, 
the  front  paws  have  short  thumbs,  while  the  hind  feet  are  very  much 
longer  and  have  a long  thumb  looking  very  much  like  an  elfin  hand  in  a 
gray-white  silk  glove.  On  the  bottom  of  the  feet  are  callous  spots  which 
are  pink  and  serve  as  foot 

pads.  It  makes  its  nest  in  | 

hollow  trees  and  stores  nuts  ' ^ 

for  winter  use.  We  once 
found  two  quarts  of  shelled 

beech  nuts  in  such  a nest.  It  **  — „ 

also  likes  the  hips  of  the  wild 
rose  and  many  kinds  of  ber- 
ries; it  sometimes  makes  its 
summer  home  in  a bird’s  nest, 
which  it  roofs  over  to  suit 
itself.  The  young  mice  are 
carried,  hanging  to  the  mother’s  breasts. 


Track  of  white-footed  mouse. 
Notice  tail-track. 


As  an  inhabitant  of  summer 
cottages, white-foot  is  cunning  and  mischievous ; it  pulls  cotton  out  of  quilts 
takes  covers  off  of  jars,  and  as  an  explorer,  is  equal  to  the  squirrel.  I once 
tried  to  rear  some  young  deer  mice  by  feeding  them  warm  milk  with  a 
pipette;  although  their  eyes  were  not  open,  they  invariably  washed  their 
faces  after  each  meal,  showing  that  neatness  was  bred  in  the  bone.  This 
mouse  has  a musical  voice  and  often  chirps  as  sweetly  as  a bird.  Like 
the  house  mouse  it  is  more  active  at  night. 

The  meadow  mouse  is  the  one  that  makes  its  run-ways  under  the  snow, 
making  strange  corrugated  patterns  over  the  ground  which  attract  our 
attention  in  spring.  It  has  a heavy  body,  short  legs,  short  ears  and  short 
tail.  It  is  brownish  or  blackish  in  color.  It  sometimes  digs  burrows 
straight  into  the  ground,  but  more  often  makes  its  nest  beneath  sticks  and

stones  or  stacks  of  com.  It  is  the  nest  of  this  field  mouse  which  the 
bumblebee  so  often  takes  possession  of,  after  it  is  deserted.  The  meadow 
mouse  is  a good  fighter,  sitting  up  like  a woodchuck  and  facing  its  enemy 
bravely.  It  needs  to  be  courageous,  for  it  is  preyed  upon  by  almost  every 
creature  that  feeds  upon  small  animals;  the  hawks  and  owls  especially 
are  its  enemies.  It  is  well  for  the  farmer  that  these  mice  have  so  many 
enemies,  for  they  multiply  rapidly  and  would  otherwise  soon  overrun  and 
destroy  the  grain  fields.  This  mouse  is  an  excellent  swimmer. 

A part  of  winter  work,  is  to  make  the  pupils  familiar  with  the  tracks 
of  the  meadow  mice  and  how  to  distinguish  them  from  other  tracks.

Figure  4.  trap. 


Trapping  Field  Mice — Probably  wild  animals  have  endured  more 
cruelty  through  the  agency  of  traps  than  through  any  other  form  of 
human  persecution.  The  savage  steel  traps  often  catch  the  animal  by  the 
leg,  holding  it  until  it  gnaws  off  the  imprisoned  foot,  and  thus  escapes 
maimed  and  handicapped  for  its  future  struggle  for  food ; or  if  the  trap 
gets  a strong  hold,  the  poor  creature  may  suffer  tortures  during  a long 
period,  before  the  owner  of  the  trap  appears  to  put  an  end  to  its  sufferings 
by  death.  If  box  traps  are  used,  they  are  often  neglected  and  the  poor 
creature  imprisoned,  is  left  to  languish  and  starve.  The  teacher  cannot 
enforce  too  strongly  upon  the  child  the  ethics  of  trapping.  Impress 
upon  him  that  the  box  traps  are  far  less  cruel;  but  that  if  set,  they  must 
be  examined  regularly  and  not  neglected.  The  study  of  mice  affords  a 
good  opportunity  for  giving  the  children  a lesson  in  humane  trapping. 
Let  them  set  a figure  4 or  a bowl  trap,  which  they  must  examine 
every  morning.  The  little  prisoners  may  be  brought  to  school 
and  studied;  meanwhile,  they  should  be  treated  kindly  and  fed  bounti- 
fully. After  a mouse  has  been  studied,  it  should  be  set  free,  even  though 
it  be  one  of  the  quite  pestiferous  field  mice.  The  moral  effect  of  killing  an 
animal,  after  a child  has  become  thoroughly  interested  in  it  and  its  life, 
is  always  bad.

LESSON  LV 
The  House  Mouse 

Leading  thought — The  mouse  is  fitted  by  color,  form,  agility  and  habits 
to  thrive  upon  the  food  which  it  steals  from  man,  and  to  live  in  the  midst 
of  civilized  people. 

Method — A mouse  cage  can  be  easily  made  of  wire  window-screen 
tacked  upon  a wooden  frame.  I have  even  used  aquarium  jars  with  wire 
screen  covers,  and  by  placing  one  jar  upon  another,  opening  to  opening, 
and  then  laying  them  horizontal,  the  mouse  can  be  transferred  to  a fresh 
cage  without  trouble,  and  thus  the  mousey  odor  can  be  obviated,  while 
the  little  creature  is  being  studied.  A little  water  in  a wide-necked  bottle 
can  be  lowered  into  this  glass  house  by  a string,  and  the  food  can  be  given 
in  like  manner.  Stripped  paper  should  be  put  into  the  jar  for  the  comfort 
of  the  prisoner;  a stiff  string  hanging  down  from  the  middle  of  the  cage 
will  afford  the  prisoner  a chance  to  show  his  feats  as  an  acrobat. 

Observations — -i . Why  is  the  color  of  the  mouse  of  special  benefit  to  it  ? 
Do  you  think  it  protects  it  from  the  sight' of  its  enemies?  Can  you  see  a 
mouse  easily  as  it  runs  across  the  room  ? What  is  the  nature  of  the  fur  of 
a mouse? 

2.  How  long  is  a mouse’s  tail  as  compared  with  its  body?  What  is  the 
covering  of  the  tail?  Of  what  use  to  the  mouse  is  this  long,  ridged  tail? 
Watch  the  mouse  carefully  and  discover,  if  you  can,  the  use  of  the  tail  in 
climbing. 

3.  Is  the  mouse  a good  jumper?  Are  the  hind  legs  long  and  strong 
when  compared  with  the  front  legs?  How  high  do  you  think  a mouse 
can  jump?  Do  you  think  it  uses  its  tail  as  an  aid  in  jumping?  How 
much  of  the  legs  are  covered  with  hair?  Compare  the  front  and  hind  feet. 
What  sort  of  claws  have  they?  How  does  the  mouse  use  its  feet  when 
climbing  the  string?  How  can  it  climb  up  the  side  of  a wall? 

4.  Describe  the  eyes.  Do  you  think  the  mouse  can  see  very  well? 
Does  it  wink?  What  is  the  shape  of  the  ears ? Do  you  think  it  can  hear 
well?  Can  it  move  its  ears  forward  or  backward? 

5.  What  is  the  shape  of  the  snout?  Of  what  advantage  is  this? 
Note  the  whiskers.  What  is  their  use?  Describe  the  mouth.  Do  you 
know  how  the  teeth  are  arranged?  For  what  other  use  than  to  bite  food 
does  the  mouse  use  its  teeth?  What  other  animals  have  their  teeth 
arranged  like  those  of  the  mouse?  What  food  does  the  house  mouse  live 
upon?  How  does  it  get  it? 

6.  How  does  the  mouse  act  when  it  is  reaching  up  to  examine  some- 
thing? How  does  it  hold  its  front  feet  ? Describe  how  the  mouse  washes 
its  face.  Its  back.  Its  feet. 

7.  Where  does  the  house  mouse  build  its  nest?  Of  what  material? 
How  do  the  baby  mice  look  ? Can  they  see  when  they  are  first  bom  ? 

8.  House  mice  are  great  travelers.  Can  you  tell  how  they  manage 
to  get  from  place  to  place?  Write  a story  telling  all  you  know  of  their 
habits. 

9.  How  many  kinds  of  mice  do  you  know?  Does  the  house  mouse 
ever  live  in  the  field  ? What  do  you  know  of  the  habits  of  the  white-footed 
mouse?  Of  the  meadow  mice?  Of  the  jumping  mice?

THE  WOODCHUCK 

Teacher's  Story 

E who  knows  the  ways  of  the  woodchuck  can 
readily  guess  where  it  is  likely  to  be  found; 
it  loves  meadows  and  pastures  where  grass  or 
clover  lushly  grows.  It  is  also  fond  of  garden 
truck  and  has  a special  delectation  for  melons. 
The  burrow  is  likely  to  be  situated  near  a fence 
or  stone  heap,  which  gives  easy  access  to  the 
chosen  food.  The  woodchuck  makes  its 
burrow  by  digging  the  earth  loose  with-  its 
front  feet,  and  pushing  it  backward  and  out  of 
the  entrance  with  the  hind  feet.  This  method 
leaves  the  soil  in  a heap  near  the  entrance,  from  which  paths  radiate  into 
the  grass  in  all  directions.  If  one  undertakes  to  dig  out  a woodchuck,  one 
needs  to  be  not  only  a husky  individual,  but  something  of  an  engineer; 
the  direction  of  the  burrow  extends  downward  for  a little  way,  and  then 
rises  at  an  easy  angle,  so  that  the  inmate  may  be  in  no  danger  of  flood. 
The  nest  is  merely  an  enlargement  of  the  burrow,  lined  with  soft  grass, 
which  the  woodchucks  bring  in  in  their  mouths.  During  the  early  part 
of  the  season,  the  father  and  mother  and  the  litter  of  young  may  inhabit 
the  same  burrow,  although  there  are  likely  to  be  at  least  two  separate 
nests.  There  is  usually  more  than  one  back  door  to  the  woodchuck’s 
dwelling,  through  which  it  may  escape,  if  pressed  too  closely  by  enemies; 
these  back  doors  differ  from  the  entrance,  in  that  they  are  usually  hidden 
and  have  no  earth  heaped  near  them. 

The  woodchuck  usually  feeds  in  the  morning  and  again  in  the  evening, 
and  is  likely  to  spend  the  middle  of  the  day  resting.  It  often  goes  some 
distance  from  its  burrow  to  feed,  and  at  short  intervals,  lifts  itself  upon 
its  hind  feet  to  see  if  the  coast  is  clear;  if  assailed,  it  will  seek  to  escape 
by  running  to  its  burrow;  and  when  running,  it  has  a peculiar  gait  well 
described  as  “pouring  itself  along.”  If  it  reaches  its  burrow,  it  at  once 
begins  to  dig  deeply  and  throw  the  earth  out  behind  it,  thus  making  a 
wall  to  keep  out  the  enemy.  When  cornered,  the  woodchuck  is  a coura- 
geous and  fierce  fighter;  its  sharp  incisors  prove  a powerful  weapon  and  it 
will  often  whip  a dog  much  larger  than  itself.  Every  boy  knows  how  to 
find  whether  the  woodchuck  is  in  its  den  or  not,  by  rolling  a stone  into  the 
burrow,  and  listening;  if  the  animal  is  at  home,  the  sound  of  its  digging 
apprises  the  listener  of  the  fact.  In  earlier  times,  the  ground-hogs  were 
much  preyed  upon  by  wolves,  wildcats  and  foxes;  now,  only  the  fox 
remains  and  he  is  fast  disappearing,  so  that  at  present,  the  farmer  and  his 
dog  are  about  the  only  enemies  this  burro wer  has  to  contend  with.  It  is 
an  animal  of  resources  and  will  climb  a tree  if  attacked  by  a dog;  it  will 
also  climb  trees  for  fruit,  like  peaches.  During  the  late  summer,  it  is  the 
ground-hog’s  business  to  feed  very,  constantly  and  become  very  fat. 
About  the  first  of  October,  it  retires  to  its  den  and  sleeps  until  the  end  of 
March  or  April.  During  this  dormant  state,  the  beating  of  its  heart  is  so 
faint  as  to  be  scarcely  perceptible,  and  very  little  nourishment  is  required 
to  keep  it  alive ; this  nourishment  is  supplied  by  the  fat  stored  in  its  body, 
which  it  uses  up  by  March,  and  comes  out  of  its  burrow  in  the  spring,  look- 
ing gaunt  and  lean.  The  old  saying  that  the  ground-hog  comes  out  on 


230

Candlemas  Day,  and  if  it  sees  its  shadow,  goes  back  to  sleep  for  six  weeks 
more,  may  savor  of  meteorological  truth,  but  it  is  certainly  not  true  of  the 
ground-hog. 

The  full-grown  woodchuck  ordinarily  measures  about  two  feet  in 
length.  Its  color  is  grizzly  or  brownish,  sometimes  blackish  in  places; 
the  under  parts  are  reddish  and  the  feet  black.  The  fur  is  rather  coarse, 
thick  and  brown,  with  longer  hairs  which  are  grayish.  The  skin  is  very 
thick  and  tough  and  seems  to  fit  loosely,  a condition  which  gives  the 
peculiar  “pouring  along”  appearance  when  it  is  running.  The  hind  legs 
and  feet  are  longer  than  those  in  front.  Both  pairs  of  feet  are  fitted  for 
digging,  the  front  ones  being  used  for  loosening  the  earth  and  the  hind 
pair  for  kicking  it  out  of  the  burrow. 

The  woodchuck’s  ears  are  roundish  and  not  prominent,  and  by  mus- 
cular contraction  they  are  closed  when  the  animal  is  digging,  so  that  no 

soil  can  enter;  the 
sense  of  hearing  is 
acute.  The  teeth  con- 
sist of  two  large  in- 
cisors at  the  front  of 
each  jaw,  a bare  space 
and  four  grinders  on 
each  side,  above  and 
below;  the  incisors 
are  used  for  biting 
food  and  also  for  fight- 
ing. The  eyes  are  full 
and  bright.  The  tail 
is  short  and  brushy, 
and  it  with  the  hind 
legs,  form  a tripod 
which  supports  the 
animal,  as  it  sits  with 
its  forefeet  lifted. 

When  feeding,  the 
woodchuck  often 
makes  a contented 
grunting  noise ; when 
attacked  and  fighting, 
it  growls;  and  when 
feeling  happy  and  con- 
versational, it  sits  up 
and  whistles.  I had  a 
woodchuck  acquaint- 
ance once  which  al- 
Treed!  ways  gave  a high, 

Photo  by  Verne  Morton.  shrill,  almost  birdlike 

whistle  when  I came  in  view,  a very  jolly  greeting.  There  are 
plenty  of  statements  in  books  that  woodchucks  are  fond  of  music,  and 
Mr.  Ingersoll  states  that  at  Wellesley  College  a woodchuck  on  the  chapel 
lawn  was  wont  to  join  the  morning  song  exercises  with  a “clear  soprano.” 
The  young  woodchucks  are  born  about  the  first  of  May  and  the  litter 
usually  numbers  four  or  five.  In  June  the  “chucklings”  may  be  seen 
following  the  mother  in  the  field  with  much  babyish  grunting.  If

captured  at  this  period,  they  make  every  interesting  pets.  By  August  or 
September  the  young  woodchucks  leave  the  home  burrow  and  start 
burrows  of  their  own.

LESSON  LVI 

The  Woodchuck  or  Ground-Hog 

Leading  thought — The  woodchuck  has  thriven  with  civilization,  not- 
withstanding the  farmer’s  dog,  gun,  traps  and  poison.  It  makes  its  nest 
in  a burrow  in  the  earth  and  lives  upon  vegetation;  it  hibernates  in 
winter. 

Method — Within  convenient  distance  for  observation  by  the  pupils  of 
every  country  schoolhouse  and  of  most  village  schoolhouses,  maybe 
found  a woodchuck  and  its  dwelling.  The  pupils  should  be  given  the 
outline  for  observations  which  should  be  made  individually  through 
watching  the  woodchuck  for  weeks  or  months. 

Observations — 1.  Where  is  the  woodchuck  found?  On  what  does  it 
live  ? At  what  time  of  day  does  it  feed  ? How  does  it  act  when  startled  ? 

2.  Is  the  woodchuck  a good  fighter?  With  what  weapons  does  it 
fight  ? What  are  its  enemies  ? How  does  it  escape  its  enemies  when  in  or 
out  of  its  burrow?  How  does  it  look  when  running? 

3 . What  noises  does  the  woodchuck  make  and  what  do  they  mean  ? 
Play  a “mouth-organ”  near  the  woodchuck’s  burrow  and  note  if  it  likes 
music. 

4.  How  does  the  woodchuck  make  its  burrow?  Where  is  it  likely 
to  be  situated  ? Where  is  the  earth  placed  which  is  taken  from  the  bur- 
row? How  does  the  woodchuck  bring  it  out  ? How  is  the  burrow  made 
so  that  the  woodchuck  is  not  drowned  in  case  of  heavy  rains?  In  what 
direction  do  the  underground  galleries  go?  Where  is  the  nest  placed  in 
relation  to  the  galleries  ? Of  what  is  the  nest  made  ? How  is  the  bedding 
carried  in?  Of  what  special  use  is  the  nest? 

5.  Do  you  find  paths  leading  to  the  entrances  of  the  burrow?  If  so, 
describe  them.  How  can  you  tell  whether  a woodchuck  is  at  home  or  not 
if  you  do  not  see  it  enter?  Where  is  the  woodchuck  likely  to  station  itself 
when  it  sits  up  to  look  for  intruders? 

6.  How  many  woodchucks  inhabit  the  same  burrow?  Are  there 
likely  to  be  one  or  more  back  doors  to  the  burrow?  What  for?  How  do 
the  back  doors  differ  from  the  front  doors  ? 

7.  How  long  is  the  longest  woodchuck  that  you  have  ever  seen? 
What  is  the  woodchuck’s  color?  Is  its  fur  long  or  short ? Coarse  or  fine? 
Thick  or  sparse?  Is  the  skin  thick  or  thin?  Does  it  seem  loose  or  close 
fitting? 

8.  Compare  the  front  and  hind  feet  and  describe  difference  in  size  and 
shape.  Are  either  or  both  slightly  webbed  ? Explain  how  both  front  and 
hind  feet  and  legs  are  adapted  by  their  shape  to  help  the  woodchuck.  Is 
the  tail  long  or  short  ? How  does  it  assist  the  animal  in  sitting  up  ? 

9.  What  is  the  shape  of  the  woodchuck’s  ear?  Can  it  hear  well? 
Why  are  the  ears  not  filled  with  soil  when  the  animal  is  burrowing?  Of 
what  use  are  the  long  incisors?  Describe  the  eyes.

10.  How  does  the  woodchuck  prepare  for  winter?  Where  and  how 
does  it  pass  the  winter?  Did  you  ever  know  a woodchuck  to  come  out  on 
Candlemas  Day  to  look  for  its  shadow? 

11.  When  does  the  woodchuck  appear  in  the  spring?  Compare  its 
general  appearance  in  the  fall  and  in  the  spring  and  explain  the  reason  for 
the  difference. 

12.  When  are  the  young  woodchucks  bom?  What  do  you  know  of 
the  way  the  mother  woodchuck  cares  for  her  young? 

As  I turned  round  the  corner  of  Hubbard's  Grove , saw  a woodchuck,  the  first  of 
the  season,  in  the  middle  of  the  field  six  or  seven  rods  from  the  fence  which  bounds  the 
wood,  and  twenty  rods  distant.  I ran  along  the  fence  and  cut  him  off,  or  rather  overtook 
him,  though  he  started  at  the  same  time.  When  I was  only  a rod  and  a half  off,  he 
stopped,  and  I did  the  same;  then  he  ran  again,  and  I ran  up  within  three  feet  of  him, 
when  he  stopped  again,  the  fence  being  between  us.  I squatted  down  and  surveyed  him 
at  my  leisure.  His  eyes  were  dull  black  and  rather  inobvious,  with  a faint  chestnut 
iris,  with  but  little  expression  and  that  more  of  resignation  than  of  anger.  The  general 
aspect  was  a coarse  grayish  brown,  a sort  of  grisel.  A lighter  brown  next  the  skin,  then 
black  or  very  dark  brown  and  tipped  with  whitish  rather  loosely.  The  head  between  a 
squirrel  and  a bear,  flat  on  the  top  and  dark  brown,  and  darker  still  or  black  on  the  tip 
of  the  nose.  The  whiskers  black,  two  inches  long.  The  ears  very  small  and  roundish, 
set  far  back  and  nearly  buried  in  the  fur.  Black  feet,  with  long  and  slender  claws  for 
digging.  It  appeared  to  tremble,  or  perchance  shivered  with  cold.  When  I moved,  it 
gritted  its  teeth  quite  loud,  sometimes  striking  the  under  jaw  against  the  other  chatter- 
ingly,  sometimes  grinding  one  jaw  on  the  other,  yet  as  if  more  from  instinct  than  anger. 
Whichever  way  1 turned,  that  way  it  headed.  I took  a twig  a foot  long  and  touched  its 
snout,  at  which  it  started  forward  and  bit  the  stick,  lessening  the  distance  between  us  to 
two  feet,  and  still  it  held  all  the  ground  it  gained.  I played  with  it  tenderly  awhile  with 
the  stick,  trying  to  open  its  gritting  jaws.  Ever  its  long  incisors,  two  above  and  two 
below,  were  presented.  But  I thought  it  would  go  to  sleep  if  I stayed  long  enough.  It 
did  not  sit  upright  as  sometimes,  but  standing  on  its  fore  feet  with  its  head  down,  i.  e., 
half  sitting,  half  standing.  We  sat  looking  at  one  another  about  half  an  hour,  till  we 
began  to  feel  mesmeric  influences.  When  I was  tired,  I moved  away,  wishing  to  see 
him  run,  but  I could  not  start  him.  He  would  not  stir  as  long  as  I was  looking  at  him 
or  could  see  him.  I walked  around  him;  he  turned  as  fast  and  fronted  me  still.  I sat 
down  by  his  side  within  a foot.  I talked  to  him  quasi  forest  lingo,  baby-talk,  at  any  rate 
in  a concilatory  tone,  and  thought  that  I had  some  influence  on  him.  He  gritted  his 
teeth  less.  1 chewed  checkerberry  leaves  and  presented  them  to  his  nose  at  last  without 
a grit;  though  I saw  that  by  so  much  gritting  of  the  teeth  he  had  worn  them  rapidly  and 
they  were  covered  with  a fine  white  powder,  which,  if  you  measured  it  thus,  would  have 
made  his  anger  terrible.  He  did  not  mind  any  noise  I might  make.  With  a little 
stick  I lifted  one  of  his  paws  to  examine  it,  and  held  it  up  at  pleasure.  I turned  him 
over  to  see  what  color  he  was  beneath  ( darker  or  most  pusely  brown) , though  he  turned 
himself  back  again  sooner  than  I could  have  wished.  His  tail  was  also  brown,  though 
not  very  dark,  rat-tail  like,  with  loose  hairs  standing  out  on  all  sides  like  a caterpillar 
brush.  He  had  a rather  mild  look.  I spoke  kindly  to  him.  I reached  checkerberry 
leaves  to  his  mouth.  I stretched  my  hands  over  him,  though  he  turned  up  his  head  and 
still  gritted  a little.  I laid  my  hand  on  him,  but  immediately  took  it  off  again,  instinct 
not  being  wholly  overcome.  If  I had  had  a few  fresh  bean  leaves,  thus  in  advance  of 
the  season,  I am  sure  I should  have  tamed  him  completely.  It  was  a frizzly  tail.  His 
is  a humble,  terrestrial  color  like  the  partridge' s,  well  concealed  where  dead  wiry  grass 
rises  above  darker  brown  or  chestnut  dead  leaves — a modest  color.  If  I had  had  some 
food,  I should  have  ended  with  stroking  him  at  my  leisure.  Could  easily  have  wrapped 
him  in  my  handkerchief.  He  was  not  fat  nor  particularly  lean.  I finally  had  to  leave 
him  without  seeing  him  move  from  the  place.  A large,  clumsy,  burrowing  squirrel. 
Arctomys,  bear-mouse.  I respect  him  as  one  of  the  natives.  He  lies  there,  by  his  color 
and  habits  ro  naturalized  amid  the  dry  leaves,  the  withered  grass,  and  the  bushes.  A 
sound  nap,  j too,  he  has  enjoyed  in  his  native  fields,  the  past  winter.  I think  I might 
learn  some  wisdom  of  him.  His  ancestors  have  lived  here  longer  than  mine.  He  is 
more  thoroughly  acclimated  and  naturalized  than  I.  Bean  leaves  the  red  man  raised 
for  him,  but  he  can  do  without  them. — Thoreau’s  Journal.

THE  RED  SQUIRREL  OR  CHICKAREE 

Teacher's  Story 

Just  a tawny  glimmer,  a dash  of  red  and  gray, 

Was  it  a flitting  shadow,  or  a sunbeam  gone  astray ! 

It  glances  up  a tree  trunk,  and  a pair  of  bright  eyes  glow 
Where  a little  spy  in  ambush  is  measuring  his  foe. 

I hear  a mocking  chuckle,  then  wrathful,  he  grows  bold 
And  stays  his  pressing  business  to  scold  and  scold  and  scold. 


E ought  to  yield  admiring  tribute  to  those  animals  which 
have  been  able  to  flourish  in  our  midst  despite  man  and 
his  gun,  this  weapon  being  the  most  cowardly  and 
unfair  invention  of  the  human  mind.  The  only  time 
that  man  has  been  a fair  fighter,  in  combating  his  four- 
footed  brethren,  was  when  he  fought  them  with  a 
weapon  which  he  wielded  in  his  hand.  There  is  noth- 
ing in  animal  comprehension  which  can  take  into 
account  a projectile,  and  much  less  a shot  from  a gun;  but  though  it  does 
not  understand,  it  experiences,  a deathly  fear  at  the  noise.  It  is  pathetic 
to  note  the  hush  in  a forest  that  follows  the  sound  of  a gun ; every  song, 
every  voice,  every  movement  is  stilled  and  every  little  heart  filled  with 
nameless  terror.  How  any  man  or  boy  can  feel  manly  when,  with  this 
scientific  instrument  of  death  in  his  hands,  he  takes  the  life  of  a little 
squirrel,  bird  or  rabbit,  is  beyond  my  comprehension.  In  pioneer  days 
when  it  was  a fight  for  existence,  man  against  the  wilderness,  the  matter 
was  quite  different ; but  now  it  seems  to.  me  that  anyone  who  hunts  what 
few  wild  creatures  we  have  left,  and  which  are  in  nowise  injurious,  is, 
whatever  he  may  think  of  himself,  no  believer  in  fair  play. 

Within  my  own  memory,  the  beautiful  black  squirrel  was  as  common 
in  our  woods  as  was  his  red  cousin ; the  shot-gun  has  exterminated  this 
splendid  species.  Well  may  we  rejoice  that  the  red  squirrel  has,  through 
its  lesser  size  and  greater  cunning,  escaped  a like  fate;  and  that  pug- 
nacious and  companionable  and  shy,  it  lives  in  our  midst  and  climbs  our 
very  roofs  to  sit  there  and  scold  us  for  coming  within  its  range  of  vision.

It  has  succeeded  not  only  in  living  despite  of  man,  but  because  of  man,  for 
it  rifles  our  grain  bins  and  com  cribs  and  waxes  opulent  by  levying  tribute 
upon  our  stores. 

Thoreau  describes  most  graphically  the  movements  of  this  squirrel. 
He  says:  “All  day  long  the  red  squirrels  came  and  went.  One  would 

approach  at  first  warily,  warily,  through  the  shrub-oaks,  running  over  the 
snow  crust  by  fits  and  starts  and  like  a leaf  blown  by  the  wind,  now  a few 
paces  this  way,  with  wonderful  speed  and  waste  of  energy,  making  incon- 
ceivable haste  with  his  “trotters,”  as  if  it  were  for  a wager,  and  now  as 
many  paces  that  way,  but  never  getting  on  more  than  half  a rod  at  a 
time;  and  then  suddenly  pausing  with  a ludicrous  expression  and  a 
gratuitous  somersault,  as  if  all  the  eyes  of  the  universe  were  fixed  on  him, 
* * * and  then  suddenly,  before  you  could  say  Jack  Robinson  he 

would  be  in  the  top  of  a young  pitch  pine,  winding  up  his  clock,  and 
chiding  all  imaginary  spectators,  soliloquizing  and  talking  to  all  the 
universe  at  the  same  time.” 

It  is  surely  one  of  the  most  comical  of  sights  to  see  a squirrel  stop 
running  and  take  observations ; he  lifts  himself  on  his  haunches,  and  with 
body  bent  forward,  presses  his  little  paws  against  his  breast  as  if  to  say, 
“Be  still,  oh  my  beating  heart!”  which  is  all  pure  affectation  because  he 
knows  he  can  scurry  away  in  perfect  safety.  He  is  likely  to  take  refuge 
on  the  far  side  of  a tree,  peeping  out  from  this  side  and  that,  and  whisking 
back  like  a flash  as  he  catches  our  eye ; we  might  never  know  he  was  there 
except  as  Riley  puts  it,  “he  lets  his  own  tail  tell  on  him.”  When  climbing 
up  or  down  a tree,  he  goes  head  first  and  spreads  his  legs  apart  to  clasp  as 
much  of  the  trunk  as  possible;  meanwhile  his  sharp  little  claws  cling 

securely  to  the  bark. 
He  can  climb  out  on 
the  smallest  twigs 
quite  as  well,  when 
he  needs  to  do  so,  in 
passing  from  tree  to 
tree  or  when  gather- 
ing acorns. 

A squirrel  always 
establishes  certain 
roads  to  and  from 
his  abiding  place 
and  almost  invar- 
iably follows  them. 
Such  a path  may  be 
entirely  in  the  tree- 
tops,  with  airbridges 
from  a certain 
branch  of  one  tree 
to  a certain  branch 
of  another,  or  it  may 
be  partially  on  the 
ground  between 
trees.  I have  made 
notes  of  these  paths 
Red  squirrel  or  Chickaree.  in  the  vicinity  of 


Mammal  Study 


235 


my  own  home,  and  have  noted  that  if  a squirrel  leaves  them  for  ex- 
ploring, he  goes  warily;  while,  when  following  them,  he  is  quite  reckless 
in  his  haste.  When  making  a jump  from  tree  to  tree,  he  flattens  himself 
as  widely  as  possible  and  his  tail  is  held  somewhat  curved,  but  on  a 
level  with  the  body,  as  if  its  wide  brush  helped  to  buoy  him  up 
and  perhaps  to  steer  him  also. 

During  the  winter  the  chickaree  is  quite  dingy  in  color  and  is  an 
inconspicuous  object,  especially  when  he  “humps  himself  up”  so 
that  he  resembles  a knot  on  a limb ; but  with  the  coming  of  spring, 
he  dons  a brighter  coat  of  tawny-red  and  along  his  sides,  where 
the  red  meets  the  grayish  white  of  the  under  side,  there  is  a 
dark  line  which  is  very  ornamental;  and  now  his  tail  is  a shower 
of  ruddiness.  As  the  season  advances,  the  colors  seem  to  fade; 
they  are  probably  a part  of  his  wooing  costume.  When  dashing  up  a tree 
trunk,  his  color  is  never  very  striking  but  looks  like  the  glimmer  of  sun- 
light ; this  has  probably  saved  many  of  his  kind  from  the  gunner,  whose 
eyes  being  at  the  front  of  his  head,  cannot  compare  in  efficiency  with 
those  of  the  squirrel,  which  being  large  and  full  and  alert,  are  placed  at 
the  sides  of  the  head  so  as  to  see  equally  well  in  all  directions. 

The  squirrel’s  legs  are  short  because  he  is  essentially  a climber  rather 
than  a runner;  the  hips  are  very  strong  which  insures  his  power  as  a 
jumper  and  his  leaps  are  truly  remarkable.  A squirrel  uses  his  front 
paws  for  hands  in  a most  human  way;  with  them  he  washes  his  face  and 
holds  his  food  up  to  his  mouth  while  eating,  and  it  is  interesting  to  note 
the  skill  of  his  claws  when  used  as  fingers.  The  track  he  makes  in  the 
snow  is  quite  characteristic.  The  tracks  are  paired  and  those  of  the  large 
five-toed  hind  feet  are  always  in  front. 


Squirrel  tracks. 

The  squirrel  has  two  pairs  of  gnawing  teeth  which  are  very  long  and 
strong,  as  in  all  rodents,  and  he  needs  to  keep  busy  gnawing  hard  things 
with  them,  or  they  will  grow  so  long  that  he  cannot  use  them  at  all  and 
will  starve  to  death.  He  is  very  clever  about  opening  nuts  so  as  to  get  all 
the  meats.  He  often  opens  a hickory  nut  with  two  holes  which  tap  the 
places  of  the  nut  meats  squarely;  with  walnuts  or  butternuts,  which  have 
much  harder  shells,  he  makes  four  small  holes,  one  opposite  each  quarter 
of  the  kernel.  He  has  no  cheek-pouches  like  a chipmunk  but  he  can  carry 
com  and  other  grain.  He  often  fills  his  mouth  so  full  that  his  cheeks 
bulge  out  like  those  of  a boy  eating  pop-corn ; but  anything  as  large  as  a 
nut  he  carries  in  his  teeth.  His  food  is  far  more  varied  than  many  sup- 
pose and  he  will  eat  almost  anything  eatable;  he  is  a little  pirate  and 
enjoys  stealing  from  others  with  keenest  zest.  In  spring,  he  eats  leaf 
buds  and  hunts  our  orchards  for  apple  seeds.  In  winter,  he  feeds  on  nuts 
and  cones;  it  is  marvelous  how  he  will  take  a cone  apart,  tearing  off  the 
scales  and  leaving  them  in  a heap  while  searching  for  seeds;  he  is  espec- 
ially fond  of  the  seeds  of  Norway  spruce  and  hemlock.  Of  course,  he  is 
fond  of  nuts  of  all  kinds  and  will  cut  the  chestnut  burs  from  the  tree 
before  they  are  ripe,  so  that  he  may  get  ahead  of  the  other  harvesters. 
He  stores  his  food  for  winter  in  all  sorts  of  odd  places  and  often  forgets 


236 


Handbook  of  Nature-Siudy 


where  he  puts  it.  We  often  find  his  winter  stores  untouched  the  next 
summer.  He  also  likes  birds’  eggs  and  nestlings,  and  if  it  were  not  for 
the  chastisement  he  gets  from  the  parent  robins,  he  would  work  much 
damage  in  this  way. 

The  squirrel  is  likely  to  be  a luxurious  fellow  and  have  a winter  and  a 
summer  home.  The  former  is  in  some  hollow  tree  or  other  protected 
place;  the  summer  home  consists  of  a platform  of  twigs  in  some  tree-top, 
often  built  upon  an  abandoned  crow  or  hawk  nest;  but  just  how  he  uses 
these  two  homes,  is  as  yet,  a matter  of  guessing  and  is  a good  subject  for 
young  naturalists  to  investigate.  During  the  winter,  he  does  not  remain 
at  home  except  in  coldest  weather,  when  he  lies  cozily  with  his  tail 
wrapped  around  him  like  a boa  to  keep  him  warm.  He  is  too  full  of 
interest  in  the  world  to  lie  quietly  long,  but  comes  out,  hunts  up  some  of 
his  stores,  and  finds  life  worth  while  despite  the  cold.  One  squirrel 
adopted  a bird  house  in  one  of  our  trees,  and  he  or  his  kin  have  lived  there 
for  years;  in  winter,  be  takes  his  share  of  the  suet  put  on  the  trees  for 
birds,  and  because  of  his  greediness,  we  have  been  compelled  to  use  picture 
wire  for  tying  on  the  suet. 

The  young  are  born  in  a protected  nest,  usually  in  the  hollow  of  a tree. 
There  are  four  to  six  young  in  a litter  and  they  appear  in  April.  If 
necessary  to  move  the  young,  the  mother  carries  the  squirrel  baby  cling- 
ing to  her  breast  with  its  arms  around  her  neck. 

The  squirrel  has  several  ways  of  expressing  his  emotions;  one  is  by 
various  curves  in  his  long  beautiful,  bushy  tail.  If  the  creatures  of  the 
wood  had  a stage,  the  squirrel  would  have  to  be  their  chief  actor.  Sur- 
prise, incredulousness,  indignation,  fear,  anger  and  joy  are  all  perfectly 
expressed  by  tail  gestures  and  also  by  voice.  As  a vocalist  he  excels ; he 
chatters  with  curiosity,  “chips”  with  surprise,  scolds  by  giving  a gutteral 
trill,  finishing  with  a falsetto  squeal.  He  is  the  only  singer  I know  who 
can  carry  two  parts  at  a time.  Notice  him  sometimes  in  the  top  of  a 
hickory  or  chestnut  tree  when  nuts  are  ripe,  and  you  will  hear  him  singing 
a duet  all  by  himself,  a high  shrill  chatter  with  a chuckling  accompani- 
ment. Long  may.  he  abide  with  us  as  an  uninvited  guest  at  our  cribs! 
For,  though  he  be  a freebooter  and  conscienceless,  yet  our  world  would 
lack  its  highest  example  of  incarnate  grace  and  activity,  if  he  were  not 
in  it. 


LESSON  LVII 

The  Red  Squirrel  or  Chickaree 

Leading  thought — The  red  squirrel  by  its  agility  and  cleverness  has 
lived  on,  despite  its  worst  enemy — man.  By  form  and  color  and  activity 
it  is  fitted  to  elude  the  hunter. 

Method — If  a pet  squirrel  in  a cage  can  be  procured  for  observation  at 
the  school,  the  observations  on  the  form  and  habits  of  the  animal  can  be 
best  studied  thus;  but  a squirrel  in  a cage  is  an  anomaly  and  it  is  far 
better  to  stimulate  the  pupils  to  observe  the  squirrels  out  of  doors.  Give 
the  following  question's,  a few  at  a time,  and  ask  the  pupils  to  report  the 
answers  to  the  entire  class.  Much  should  be  done  with  the  supplemen- 
tary reading,  as  there  are  many  interesting  squirrel  stories  illustrating  its 
habits

Observations — i.  Where  have  you  seen  a squirrel?  Does  the  squirrel 
trot  along  or  leap  when  running  on  the  ground?  Does  it  run  straight 
ahead  or  stop  at  intervals  for  observation?  How  does  it  look?  How 
does  it  act  when  looking  to  see  if  the  “coast  is  clear”? 

2.  When  climbing  a tree,  does  it  go  straight  up,  or  move  around  the 
trunk?  How  does  it  hide  itself  behind  a tree  trunk  and  observe  the 
passer-by?  Describe  how  it  manages  to  climb  a tree?  Does  it  go  down 
the  tree  head  first  ? Is  it  able  to  climb  out  on  the  smallest  branches?  Of 
what  advantage  is  this  to  it? 

3.  Look  closely  and  see  if  a squirrel  follows  the  same  route  always 
when  passing  from  one  point  to  another.  How  does  it  pass  from  tree  to 
tree?  How  does  it  act  when  preparing  to  jump?  Hew  does  it  hold  its 
legs  and  tail  when  in  the  air  during  a jump  from  branch  to  branch? 

4.  Describe  the  colors  of  the  red  squirrel  above  and  below.  Is  there  a 
dark  stripe  along  its  side,  if  so,  what  color?  How  does  the  color  of  the 
squirrel  protect  it  from  its  enemies  ? Is  its  color  brighter  in  summer  or  in 
winter  ? 

5.  How  are  the  squirrel’s  eyes  placed?  Do  you  think  it  can  see 
behind  as  well  as  in  front  all  the  time?  Are  its  eyes  bright  and  alert,  or 
soft  and  tender? 

6.  Are  its  legs  long  or  short?  Are  its  hind  legs  stronger  and  longer 
than  the  front  legs?  Why?  Why  does  it  not  need  long  legs?  Does  its 
paws  have  claws?  How  does  it  use  its  paws  when  eating  and  in  making 
its  toilet  ? 

7.  Describe  the  squirrel’s  tail.  Is  it  as  long  as  the  body?  Is  it 
used  to  express  emotion ? Of  what  use  is  it  when  the  squirrel  is  jumping? 
Of  what  use  is  it  in  the  winter  in  the  nest  ? 

8.  What  is  the  food  of  the  squirrel  during  the  autumn?  Winter? 
Spring?  Summer?  Where  does  it  store  food  for  the  winter?  Does  it 
steal  food  laid  up  by  jays,  chipmunks,  mice  or  other  squirrels  ? How  does 
it  carry  nuts  ? Has  it  cheek-pouches  like  the  chipmunk  for  carrying  food  ? 
Does  it  stay  in  its  nest  all  winter  living  on  stored  food  like  a chipmunk? 

9.  Where  does  the  red  squirrel  make  its  winter  home?  Does  it  also 
have  a summer  home,  if  so,  of  what  is  it  made  and  where  built?  In  what 
sort  of  a nest  are  the  young  bom  and  reared?  At  what  time  of  the  year 
are  the  young  bom  ? How  does  the  mother  squirrel  carry  her  little  ones 
if  she  wishes  to  move  them? 

10.  How  much  of  squirrel  language  can  you  understand?  How  does 
it  express  surprise,  excitement,  anger,  or  joy  during  the  nut  harvest? 
Note  how  many  different  sounds  it  makes  and  try  to  discover  what  they 
mean. 

1 1 . Describe  or  sketch  the  tracks  made  by  the  squirrel  in  the  snow. 

1 2.  How  does  the  squirrel  get  at  the  meats  of  the  hickory  nut  and  the 
walnut?  How  are  its  teeth  arranged  to  gnaw  holes  in  such  hard  sub- 
stances as  shells  ?

FURRY 


'URRY  was  a baby  red  squirrel.  One  day 
in  May  his  mother  was  moving  him  from 
one  tree  to  another.  He  was  clinging 
with  his  little  arms  around  her  neck  and 
his  body  clasped ‘tightly  against  her  breast, 
when  something  frightened  her  and  in  her 
sudden  movement,  she  dropped  her  heavy 
baby  in  the  grass.  Thus,  I inherited  him 
and  entered  upon  the  rather  onerous 
duties  of  caring  for  a baby  of  whose  needs  I knew  little ; but  I knew  that 
every  well  cared  for  baby  should  have  a book  detailing  all  that  happens  to 
it,  therefore,  I made  a book  for  Furry,  writing  in  it  each  day  the  things 
he  did.  If  the  children  who  have  pets  keep  similar  books,  they  will  find 
them  most  interesting  reading  afterward,  and  they  will  surely  enjoy 
the  writing  very  much. 

Extracts  from  Furry's  Note -book 

May  1 8,  1902 — The  baby  squirrel  is  just  large  enough  to  cuddle  in  one 
hand.  He  cuddles  all  right  when  once  he  is  captured;  but  he  is  a terrible 
fighter,  and  when  I attempt  to  take  him  in  my  hand,  he  scratches  and 
bites  and  growls  so  that  I have  been  obliged  to  name  him  Fury.  I told 
him,  however,  if  he  improved  in  temper  I would  change  his  name  to  Furry. 

May  19 — Fury  greets  me,  when  I open  his  box,  with  the  most  awe- 
inspiring little  growls,  which  he  calculates  will  make  me  turn  pale  with 
fear.  He  has  not  cut  his  teeth  yet,  so  he  cannot  bite  very  severely,  but 
that  isn’t  his  fault,  for  he  tries  hard  enough.  The  Naturalist  said  cold 
milk  would  kill  him,  so  I warmed  the  milk  and  put  it  in  a teaspoon  and 
placed  it  in  front  of  his  nose;  he  batted  the  spoon  with  both  forepaws 
and  tried  to  bite  it,  and  thus  got  a taste  of  the  milk,  which  he  drank  eagerly 
lapping  it  up  like  a kitten.  When  I hold  him  in  one  hand  and  cover  him 
with  the  other,  he  turns  contented  little  somersaults  over  and  over. 

May  20 — Fury  bit  me  only  once  to-day,  when  I took  him  out  to  feed 
him.  He  is  cutting  his  teeth  on  my  devoted  fingers.  I tried  giving  him 
grape-nuts  soaked  in  milk,  but  he  spat  it  out  in  disgust.  Evidently  he 
does  not  believe  he  needs  a food  for  brain  and  nerve.  He  always  washes 
his  face  as  soon  as  he  is  through  eating. 

May  21 — Fury  lies  curled  up  under  his  blanket  all  day.  Evidently 
good  little  squirrels  stay  quietly  in  the  nest,  when  the  mother  is  not  at 
home  to  give  them  permission  to  run  around.  When  Fury  sleeps,  he  rolls 
himself  up  in  a little  ball  with  his  tail  wrapped  closely  around  him.  The 
squirrel’s  tail  is  his  “furs,”  which  he  wraps  around  him  to  keep  his  back 
warm  when  he  sleeps  in  winter. 

May  23 — Every  time  I meet  Uncle  John  he  asks,  “Is  his  name  Fury  or 
Furry  now?”  Uncle  John  is  much  interested  in  the  good  behavior  of  even 
little  squirrels.  As  Fury  has  not  bitten  me  hard  for  two  days,  I think  I 
will  call  him  Furry  after  this.  He  ate  some  bread  soaked  in  milk  to-day, 
holding  it  in  his  hands  in  real  squirrel  fashion.  I let  him  run  around  the 
room  and  he  liked  it. 

May  25 — Furry  got  away  from  me  this  morning  and  I did  not  find  him 
for  an  hour.  Then  I discovered  him  in  a pasteboard  box  of  drawing 
paper  with  the  cover  on.  How  did  he  squeeze  through?

May  26 — He  holds  the  bowl  of  the  spoon  with  both  front  paws  while 
he  drinks  the  milk.  When  I try  to  draw  the  spoon  away,  to  fill  it  again 
after  he  has  emptied  it,  he  objects  and  hangs  on  to  it  with  all  his  little 
might,  and  scolds  as  hard  as  ever  he  can.  He  is  such  a funny,  unreason- 
able baby. 

May  28 — To-night  I gave  Furry  a walnut  meat.  As  soon  as  he  smelled 
it  he  became  greatly  excited;  he  grasped  the  meat  in  his  hands  and  ran  off 
and  hid  under  my  elbow,  growling  like  a kitten  with  its  first  mouse. 

May  30 — Since  he  tasted  nuts  he  has  lost  interest  in  milk.  The  nut 
meats  are  too  hard  for  his  new  teeth,  so  I mash  them  and  soak  them  in 
water  and  now  he  eats  them  like  a little  piggy-wig  with  no  manners  at  all. 
He  loves  to  have  me  stroke  his  back  while  he  is  eating.  He  uses  his 
thumbs  and  fingers  in  such  a human  way  that  I always  call  his  front  paws 
hands.  When  his  piece  of  nut  is  very  small  he  holds  it  in  one  hand  and 
clasps  the  other  hand  behind  the  one  which  holds  the  dainty  morsel,  so  as 
to  keep  it  safe. 

May  3 1 — When  he  is  sleepy  he  scolds  if  I disturb  him  and  turning  over 
on  his  back  bats  my  hand  with  all  of  his  soft  little  paws  and  pretends  that 
he  is  goingto  bite. 

June  4 — Furry  ranges  around  the  room  now  to  please  himself.  He  is  a 
little  mischief;  he  tips  over  his  cup  of  milk  and  has  commenced  gnawing 
off  the  wall  paper  behind  the  book-shelf  to  make  him  a nest.  The  paper  is 
green  and  will  probably  make  him  sorry. 

June  5 — This  morning  Furry  was  hidden  in  a roll  of  paper.  I put  my 
hand  over  one  end  of  the  roll  and  then  reached  in  with  the  other  hand  to 
get  him;  but  he  got  me  instead,  because  he  ran  up  my  sleeve  and  was 
much  more  contented  to  be  there  than  I was  to  have  him.  I was  glad 
enough  when  he  left  his  hiding  place  and  climbed  to  the  top  shelf  of  the 
bookcase,  far  beyond  my  reach. 

June  6 — I have  not  seen  Furry  for  twenty-four  hours,  but  he  is  here 
surely  enough.  Last  night  he  tipped  over  the  ink  bottle  and  scattered 
nut  shells  over  the  floor.  He  prefers  pecans  to  any  other  nuts. 

June  7 — I caught  Furry  to-day  and  he  bit  my  finger  so  it  bled.  But 
afterwards,  he  cuddled  in  my  hand  for  a long  time,  and  then  climbed  my 
shoulder  and  went  hunting  around  in  my  hair  and  wanted  to  stay  there 
and  make  a nest.  When  I took  him  away,  he  pulled  out  his  two  hands 
full  of  my  devoted  tresses.  I’ll  not  employ  him  as  a hairdresser. 

June  9 — Furry  sleeps  nights  in  the  top  drawer  of  my  desk;  he  crawls 
in  from  behind.  When  I pull  out  the  drawer  he  pops  out  and  scares  me 
nearly  out  of  my  wits;  but  he  keeps  his  wits  about  him  and  gets  away 
before  I can  catch  him. 

June  20 — I keep  the  window  open  so  Furry  can  run  out  and  in  and 
learn  to  take  care  of  himself  out-of-doors. 

Furry  soon  learned  to  take  care  of  himself,  though  he  often  returned 
for  nuts,  which  I kept  for  him  in  a bowl.  He  does  not  come  very  near  me 
out-of-doors,  but  he  often  speaks  to  me  in  a friendly  manner  from  a cer- 
tain pitch  pine  tree  near  the  house. 

There  are  many  blank  leaves  in  Furry’s  note-book.  I wish  that  he 
could  have  written  on  these  of  the  things  that  he  thought  about  me  and 
my  performances.  It  would  certainly  have  been  the  most  interesting 
book  concerning  squirrels  in  the  world.

THE  CHIPMUNK 
Teacher's  Story 

HILE  the  chipmunk  is  a good  runner  and  jumper, 
it  is  not  so  able  a climber  as  is  the  red  squirrel, 
and  it  naturally  stays  nearer  the  ground. 
One  windy  day  I was  struck  by  the  peculiar 
attitude  of  what,  I first  thought,  was  a red 
squirrel  gathering  green  acorns  from  a chestnut 
oak  in  front  of  my  window.  A second  glance 
showed  me  that  it  was  a chipmunk  lying 
close  to  the  branch,  hanging  on  for  “dear  life” 
and  with  an  attitude  of  extreme  caution,  quite 
foreign  to  the  red  squirrel  in  a similar  situation.  He  would  creep  out, 
seize  an  acorn  in  its  teeth,  creep  back  to  a larger  limb,  take  off  the  shell, 
and  with  his  little  paws  stuff  the  kernel  into  his  cheek  pouches;  he  took 
hold  of  one  side  of  his  mouth  with  one  hand  to  stretch  it  out,  as  if  open- 
ing a bag,  and  stuffed  the  acorn  in  with  the  other.  I do  not  know 
whether  this  process  was  necessary  or  not  at  the  beginning,  for  his  cheeks 
were  distended  when  I first  saw  him ; and  he  kept  on  stuffing  them  until 
he  looked  as  if  he  had  a hopeless  case  of  mumps.  Then  with  obvious 
care  he  descended  the  tree  and  retreated  to  his  den  in  the  side  -hill,  the 
door  of  which  I had  already  discovered,  although  it  was  well  hidden  by 
a bunch  of  orchard  grass. 

Chipmunks  are  more  easily  tamed  than  red  squirrels  and  soon  learn 
that  pockets  may  contain  nuts  and  other  things  good  to  eat.  The  first 
tame  chipmunk  of  my  acquaintance  belonged  to  a species  found  in  the 
California  mountains.  He  was  a beautiful  little  creature  and  loved  to 
play  about  his  mistress’  room;  she  being 
a naturalist  as  well  as  a poet,  was  able 
to  understand  her  little  companion,  and 
the  relations  between  them  were  full  of 
mutual  confidence.  He  was  fond  of 
English  walnuts  and  would  always  hide 
away  all  that  were  placed  in  a dish  on 
the  table.  One  day  his  mistress,  when 
taking  off  her  bonnet  after  returning 
from  church,  discovered  several  of  these 
nuts  tucked  safely  in  the  velvet  bows; 
they  were  invisible  from  the  front  but 
perfectly  visible  from  the  side.  Even 
yet,  she  wonders  what  the  people  at 
church  that  day  thought  of  her  original 
ideas  in  millinery;  and  she  wonders 
still  more  how  “Chipsie”  managed  to 
get  into  the  bonnet-box,  the  cover  of 
which  was  always  carefully  closed. 

The  chipmunk  is  a good  home  builder 
and  carries  off,  presumably  in  its  cheek 
pouches,  all  of  the  soil  which  it  removes 

in  making  its  burrow.  The  burrow  is  “Chipsie”,  a chipmunk  of 

made  usually  in  a dry  hillside,  the  the  Sierras.

passageway  just  large  enough  for  its  own  body,  widening  to  a nest 
which  is  well  bedded  down.  There  is  usually  a back  door  also,  so  that 
in  case  of  necessity,  the  inmate  can  escape.  It  retires  to  this  nest  in 
late  November  and  does  not  appear  again  until  March.  In  the  nest, 
it  stores  nuts  and  other  grains  so  that  when  it  wakens,  at  long  inter- 
vals, it  can  take  refreshment. 

If  you  really  wish  to  know  whether  you  see  what  you  look  at  or  not, 
test  yourself  by  trying  to  describe  the  length,  position  and  number  of 
the  chipmunk’s  stripes.  These  stripes,  like  those  of  the  tiger  in  the 
jungle,  make  the  creature  less  conspicuous;  when  on  the  ground, 
where  its  stripes  fall  in  with  the  general  shape  and  color  of  the  grass 
and  underbrush,  it  is  quite  invisible  until  it  stirs.  Its  tail  is  not  so 
long  nor  nearly  so  bushy  as  that  of  the  squirrel ; it  does  not  need  a tail 
to  balance  and  steer  with  in  the  tree  tops;  and  since  it  lives  in  the 
ground,  a bushy  tail  would  soon  be  loaded  with  earth  and  would  be  an 
incubus  instead  of  a thing  of  beauty. 

The  chipmunk  is  not  a vocalist  like  the  red  squirrel,  but  he  can  cluck 
like  a cuckoo  and  chatter  gayly  or  cogently ; and  he  can  make  himself  into  a 
little  bunch  with  his  tail  curved  up  his  back,  while  he  eats  a nut  from  both 
his  hands,  and  is  even  more  amusing  than  the  red  squirrel  in  this  attitude; 
probably  because  he  is  more  innocent  and  not  so  much  of  a poseur.  His 
food  consists  of  all  kinds  of  nuts,  grain  and  fruit,  but  he  does  little  or  no 
damage,  as  a rule.  He  is  pretty  and  distinctly  companionable,  and  I 
can  rejoice,  in  that  I have  had  him  and  his  whole  family  as  my  near 
neighbors  for  many  years.  I always  feel  especially  proud  when  he  shows 
his  confidence,  by  scampering  around  our  piazza  floor  and  peeping  in  at 
our  windows,  as  if  taking  a reciprocal  interest  in  us. 

LESSON  LVIII 

The  Chipmunk 

Leading  thought — The  chipmunk  lives  more  on  the  ground  than  does 
the  squirrel;  its  colors  are  protective  and  it  has  cheek  pouches  in  which 
it  carries  food,  and  also  soil  when  digging  its  burrow.  It  stores  food  for 
winter  in  its  den. 

Method — The  field  note-book  should  be  the  basis  for  this  work. 
Give  the  pupils  an  outline  of  observations  to  be  made,  and  ask  for  reports 
now  and  then.  Meanwhile  stimulate  interest  in  the  little  creatures  by 
reading  aloud  from  some  of  the  references  given. 

Observations — 1.  Do  you  see  the  chipmunk  climbing  around  in  trees 
like  the  red  squirrel  ? How  high  in  a tree  have  you  ever  seen  a chipmunk  ? 

2.  What  are  the  chipmunk’s  colors  above  and  below?  How  many 
stripes  has  it?  Where  are  they  and  what  are  their  colors?  Do  you 
think  that  these  stripes  conceal  the  animal  when  among  grasses  and 
bushes? 

3.  Compare  the  tails  of  the  chipmunk  and  the  red  squirrel.  Which 
is  the  longer  and  bushier?  Tell  if  you  can  the  special  advantage  to  the 
chipmunk  in  having  this  less  bushy  tail  ? 

4.  What  does  the  chipmunk  eat  ? How  does  it  carry  its  food  ? How 
does  it  differ  in  this  respect  from  the  red  squirrel  ? Does  it  store  its  food 
for  winter  use  ? How  does  it  prepare  its  nuts  ? How  does  it  hold  its  food 
while  eating  ?

Handbook  of  N ature-Study 


5.  Where  does  the  chipmunk  make  its  home?  How  does  it  carry 
away  soil  from  its  burrow?  How  many  entrances  are  there?  How  is 
the  den  arranged  inside  ? Does  it  live  in  the  same  den  the  year  round  ? 
When  does  it  retire  to  its  den  in  the  fall  ? When  does  it  come  out  in  the 
spring? 

6.  Does  the  chipmunk  do  any  damage  to  crops?  What  seeds  does  it 
distribute?  At  what  time  do  the  little  chipmunks  appear  in  the  spring? 

7.  Observe  carefully  the  different  tones  of  the  chipmunk  and  com- 
pare its  chattering  with  that  of  the  squirrel.

TO  A CAPTIVE  CHIPMUNK  OF  THE  SIERRAS 

Bright  little  comrade  from  the  woods,  come  show 
Thy  antic  cheer  about  my  sunlit  room 
Of  books,  that  stand  in  moods  of  gloom 
Because  thought's  tide  is  out,  heart's  rhythm  is  low 
With  weariness.  Friendly  thou  art  and  know 
Good  friend  in  me,  who  yet  did  dare  presume 
To  take  thee  from  thy  home,  thy  little  doom 
To  make  for  thee,  and  longer  life  bestow. 

So,  thou  hast  not  been  eaten  by  the  snake; 

Thy  gentle  blood  no  weasel  drank  at  night; 

Thou  hast  not  starved  'mid  winter's  frozen  wood, 

Nor  waited  vainly  for  the  sun  to  make 

Sweet  the  wild  nuts  for  thee.  Yet,  little  sprite. 

Thou  still  doth  question  if  my  deed  were  good?

THE  LITTLE  BROWN  BAT 
Teacher's  Story 

His  small  umbrella,  quaintly  halved. 

Describing  in  the  air  an  arc  ahke  inscrutable , — 

Elate  -philosopher ! — Emily  Dickenson. 

HOEVER  first  said  “as  blind  as  a bat,”  surely  never 
looked  a bat  in  the  face,  or  he  would  not  have 
said  ib  The  deep-set,  keen,  observant  eyes  are 
quite  in  keeping  with  the  alert  attitude  of  the 
f erect,  pointed  ears;  while  the  pug-nose  and  the 

wide  open,  little,  pink  bag  of  a mouth,  set  with  tiny,  sharp  teeth,  give 
this  anomalous  little  animal  a deliciously  impish  look.  Yet  how  have 
those  old  artists  belied  the  bat,  who  fashioned  their  demons  after  his 
pattern,  ears,  eyes,  nose,  mouth,  wings  and  all!  Certain  it  is,  if  human 
beings  ever  get  to  be  winged  angels  in  this  world,  they  are  far  more  likely 
to  have  their  wings  fashioned  like  those  of  the  bat  than  like  those  of  the 
bird.  As  a matter  of  fact,  there  are  no  other  wings  so  wonderful  as  the 
bat’s;  the  thin  membrane  is  equipped  with  sensitive  nerves  which 
inform  the  flier  of  the  objects  in  his  path,  so  that  he  darts  among  the 
branches  of  trees  at  terrific  speed  and  never  touches  a twig;  a blinded  bat 
was  once  set  free  in  a room,  across  which  threads  were  stretched,  and 
he  flew  about  without  ever  touching  one.  After  we  have  tamed  one  of 
these  little,  silky  flitter-mice  we  soon  get  reconciled  to  his  wings  for  he 
proves  the  cunningest  of  pets;  he  soon  learns  who  feeds  him,  and  is  a 
constant  source  of  entertainment. 

The  flight  of  the  bat  is  the  highest  ideal  we  may  have,  for  the  achieve- 
ment of  the  aeroplane.  It  consists  of  darting  hither  and  thither  with 
incredible  swiftness,  and  making  sharp  turns  with  no  apparent  effort. 
Swifts  and  swallows  are  the  only  birds  that  can  compete  with  the  bat  in 
wing  celerity  and  agility  ; it  is  interesting  to  note  that  these  birds  also 
catch  insects  on  the  wing,  for  food.  The  bat,  like  the  swift,  keeps  his 
mouth  open,  scooping  in  all  the  insects  in  his  way;  more  than  this,  he 
makes  a collecting  net  of  the  wing  membrane,  stretched  between  the  hind 
legs  and  tail,  doubling  it  up  like  an  apron  on  the  unfortunate  insects,  and 
then  reaching  down  and  gobbling  them  up;  and  thus  he  is  always  doing 
good  service  to  us  on  summer  evenings  by  swallowing  mosquitoes  and 
gnats. 

The  short  fur  of  the  bat  is  as  soft  as  silk,  and  covers  the  body  but  not 
the  wings;  the  plan  of  the  wing  is  something  like  that  of  the  duck’s  foot; 
it  consists  of  a web  stretched  between  very  much  elongated  fingers.  If  a 
boy’s  fingers  were  as  long  in  proportion,  as  a bat’s,  they  would  measure 
four  feet.  Stretched  between  the  long  fingers  is  a thin,  rubbery  mem- 
brane, which  extends  back  to  the  ankles  and  thence  back  to  the  tip  of  the 
bony  tail;  thus,  the  bat  has  a winged  margin  all  around  his  body.  Since 
fingers  make  the  framework,  it  is  the  thumb  that  projects  from  the  front 
angle  of  the  wing,  in  the  form  of  a very  serviceable  hook,  resembling  that 
used  by  a one-armed  man  to  replace  the  lost  member.  These  hooks  the 
bat  uses  in  many  ways.  He  drags  himself  along  the  floor  with  their  aid, 
or  he  scratches  the  back  of  his  head  with  them,  if  occasion  requires.  He 
is  essentially  a creature  of  the  air  and  is  not  at  all  fitted  for  walking;  his 


244 


Handbook  oj  Nature-Study 


knees  bend  backward  in  an  opposite  direction  from  ours.  This  renders 
him  unable  to  walk,  and  when  attempting  to  do  so,  he  has  the  appeairance 
of  “scrabbling”  along  on  his  feet  and  elbows.  When  thus  movng  he 
keeps  his  wings  fluttering  rapidly,  as  if  feeling  his  way  in  the  dark,  and 
his  movements  are  trembly.  He  uses  his  teeth  to  aid  in  climbing. 

The  little  brown  bat’s  wings  often  measure  nine  inches  from  tip  to  tip, 
and  yet  he  folds  them  so  that  they  scarcely  show,  he  does  not  fold  them 
like  a fan,  but  rather  like  a pocket  knife.  The  hind  legs  merely  act  as  a 
support  for  the  side  wing,  and  the  little  hip  bones  look  pitifully  sharp; 
the  membrane  reaches  only  to  the  ankle,  the  tiny  emaciated  foot  pro- 
jecting from  it  is  armed  with  five,  wirelike  toes,  tipped  with  sharp  hooked 
claws.  It  is  by  these  claws  that  he  hangs  when  resting  during  the  day, 
for  he  is  upside-down-y  in  his  sleeping  habits,  slumbering  during  the  day- 
time, while  hanging  head  downward,  without  any  inconvenience  from  a 
rush  of  blood  to  the  brain;  when  thus  suspended,  the  tail  is  folded  down. 
Sometimes  he  hangs  by  one  hind  foot  and  a front  hook;  and  he  is  a wee 
thing  when  all  folded  together  and  hung  up,  with  his  nose  tucked  between 
his  hooked  thumbs,  in  a very  babyish  fashion. 

The  bat  is  very  particular  about  his  personal  cleanliness.  People  who 
regard  the  bat  as  a dirty  creature,  had  better  look  to  it  that  they  are  even 
half  as  fastidious  as  he.  He  washes  his  face  with  the  front  part  of  his 
wing,  and  then  licks  his  wash-cloth  clean,  he  scratches  the  back  of  his 
head  with  his  hind  foot  and  then  licks  the  foot;  when  hanging  head  down, 
he  will  reach  one  hind  foot  down  and  scratch  behind  his  ear  with  an 
aplomb  truly  comical  in  such  a mite;  but  it  is  most  fun  of  all  to  see  him 
clean  his  wings;  he  seizes  the  edges  in  his  mouth  and  stretches  and  licks 
the  membrane  until  we  are  sure  it  is  made  of  silk  elastic,  for  he  pulls  and 
hauls  it  in  a way  truly  amazing. 

The  bat  has  a voice  which  sounds  like  the  squeak  of  a toy  wheelbarrow, 
and  yet  it  is  expressive  of  emotions.  He  squeaks  in  one  tone  when  holding 
conversation  with  other  bats,  and  squeaks  quite  differently  when  seized 
by  the  enemy. 

* The  mother  bat  feeds  her  little  ones  from  her  breasts  as  a mouse  does 
its  young,  only  she  cradles  them  in  her  soft  wings  while  so  doing;  often 
she  takes  them  with  her  when  she  goes  out  for  insects  in  the  evenings; 
they  cling  to  her  neck  during  these  exciting  rides;  but  when  she  wishes  to 
work  unencumbered,  she  hangs  her  tiny  youngsters  on  some  twig  and 
goes  back  to  them  later.  The  little  ones  are  bom  in  July  and  usually 
occur  as  twins.  During  the  winter,  bats  hibernate  like  woodchucks  or 
chipmunks.  They  select  for  winter  quarters  some  hollow  tree  or  cave  or 
other  protected  place.  They  go  to  sleep  when  the  cold  weather  comes, 
and  do  not  awake  until  the  insects  are  flying ; they  then  come  forth  in  the 
evenings,  or  perhaps  early  in  the  morning,  and  do  their  best  to  rid  the 
world  of  mosquitoes  and  other  insect  nuisances. 

There  are  many  senseless  fears  about  the  bat;  for  instance,  that  he 
likes  to  get  tangled  in  a lady’s  tresses,  a situation  which  would  frighten 
him  far  more  than  the  lady;  or  that  he  brings  bedbugs  into  the  house, 
when  he  enters  on  his  quest  for  mosquitoes,  which  is  an  ungrateful  slander. 
Some  people  believe  that  all  bats  are  vampires,  and  only  await  an  oppor- 
tunity to  suck  blood  from  their  victims.  It  is  true  that  in  South  America 
there  are  two  species  which  occasionally  attack  people  who  are  careless 
enough  to  sleep  with  their  toes  uncovered,  but  feet  thus  injured  seem  to

recover  speedily;  and  these  bats  do  little  damage  to  people,  although 
they  sometimes  pester  animals;  but  there  are  no  vampires  in  the  United 
States.  Our  bats,  on  the  contrary,  are  innocent  and  beneficial  to  man; 
and  if  we  had  more  of  them  we  should  have  less  malaria.  There  a few 
species  in  our  country,  which  have  little,  leaf-like  growths  on  the  end  of 
the  nose;  and  when  scientists  study  the  bat  from  a nature-study 
instead  of  an  anatomical  standpoint,  we  shall  know  what  these  leafy 
appendages  are  used  for. 


The  little  brown  bat. 


LESSON  LIX 
The  Bat 

Leading  thought — Although  the  bat’s  wings  are  very  different  from 
those  of  the  bird’s  yet  it  is  a rapid  and  agile  flier.  It  flies  in  the  dusk  and 
catches  great  numbers  of  mosquitoes  and  other  troublesome  insects,  upon 
which  it  feeds. 

Method — This  lesson  should  not  be  given  unless  there  is  a live  bat  to 
illustrate  it;  the  little  creature  can  be  cared  for  comfortably  in  a cage  in 
the  schoolroom,  as  it  will  soon  learn  to  take  flies  or  bits  of  raw  meat  when 
presented  on  the  point  of  a pencil  or  toothpick.  Any  bat  will  do  for  this 
study,  although  the  little  brown  bat  is  the  one  on  which  my  observations 
were  made. 

Observations — 1 . At  what  time  of  day  do  we  see  bats  flying?  Describe 
how  the  bat’s  flight  differs  from  that  of  birds.  Why  do  bats  dart  about 
so  rapidly  ? 

2.  Look  at  a captive  bat  and  describe  its  wings.  Can  you  see  what 
makes  the  framework  of  the  wings?  Do  you  see  the  three  finger  bones 
extending  out  into  the  wings?  How  do  the  hind  legs  support  the  wing? 
The  tail?  Is  the  wing  membrane  covered  with  fur?  Is  it  thick  and 
leathery  or  thin  and  silky  and  elastic?  How  does  the  bat  fold  up  its 
wings  ? 

3.  In  what  position  does  the  bat  rest?  Does  it  ever  hang  by  his 
thumb  hooks? 

4.  Can  you  see  whether  the  knees  of  the  hind  legs  bend  upward  or 
downward?  How  does  the  bat  act  when  trying  to  walk  or  crawl ? How 
does  it  use  its  thumb  hooks  in  doing  this  ? 

5.  What  does  the  bat  do  daytimes?  Where  does  it  stay  during  the 
day  ? Do  many  bats  congregate  together  in  their  roosts  ? 


246 


Handbook  of  Nature-Study 


6.  Describe  the  bat’s  head,  including  the  ears,  eyes,  nose  and  mouth. 
What  is  its  general  expression?  Do  you  think  it  can  see  and  hear  well? 
How  is  its  mouth  fitted  for  catching  insects?  Does  it  shut  its  mouth 
while  chewing  or  keep  it  open?  Do  you  think  that  bats  can  see  by  day- 
light ? 

7.  What  noises  does  a bat  make?  How  does  it  act  if  you  try  to 
touch  it?  Can  it  bite  severely?  Can  you  understand  why  the  Germans 
call  it  a flitter-mouse  ? 

8.  Do  you  know  how  the  mother  bat  cares  for  her  young?  How  does 
she  carry  them?  At  what  time  of  year  may  we  expect  to  find  them? 

9.  When  making  its  toilet,  how  does  a bat  clean  its  wings?  Its  face? 
Its  back?  Its  feet?  Do  you  know  if  it  is  very  clean  in  his  habits? 

10.  How  and  where  do  the  bats  pass  the  winter?  How  are  they 
beneficial  to  us?  Are  they  ever  harmful?

Nature- study  should  not  he  unrelated  to  the  child's  life  and  circumstances.  It 
stands  for  directness  and  naturalness.  It  is  astonishing  when  one  comes  to  think  of  it, 
how  indirect  and  how  remote  from  the  lives  of  pupils  much  of  our  education  has  been. 
Geography  still  often  begins  with  the  universe,  and  finally,  perhaps,  comes  down  to 
some  concrete  and  familiar  object  or  scene  that  the  pupil  can  understand.  Arithmetic 
has  to  do  with  brokerage  and  partnerships  and  partial  payments  and  other  things  that 
mean  nothing  to  the  child.  Botany  begins  with  cells  and  protoplasm  and  cryptogams. 
History  deals  with  political  and  military  affairs,  and  only  rarely  comes  down  to  physical 
facts  and  to  those  events  that  express  the  real  lives  of  the  people;  and  yet  political  and 
social  affairs  are  only  the  results  of  expressions  of  the  way  in  which  people  live.  Read- 
ers begin  with  mere  literature  or  with  stories  of  scenes  the  child  will  never  see.  Of  course 
these  statements  are  meant  to  be  only  general,  as  illustrating  what  is  even  yet  a great 
fault  in  educational  methods.  There  are  many  exceptions,  and  these  are  becoming 
commoner.  Surely,  the  best  education  is  that  which  begins  with  the  materials  at  hand. 
A child  knows  a stone  before  it  knows  the  earth.

THE  SKUNK 
Teacher's  Story 

1^a>AMGER~)H0SE  who  have  had  experience  with  this  animal,  surely 
are  glad  that  it  is  small;  and  the  wonder  always  is, 
that  so  little  a creature  can  make  such  a large  impres- 
sion upon  the  atmosphere.  A fully  grown  skunk  is 
about  two  feet  long;  its  body  is  covered  with  long, 
shining,  rather  coarse  hair,  and  the  tail  which  is  carried 
like  a flag  in  the  air,  is  very  large  and  bushy.  In  color, 
the  fur  is  sometimes  entirely  black,  but  most  often  has  a white  patch  on 
the  back  of  the  neck,  with  two  stripes  extending  down  the  back  and 
along  the  sides  to  the  tail;  the  face,  also,  has  a white  stripe. 

The  skunk  has  a long  head  and  a rather  pointed  snout;  its  front  legs 
are  very  much  shorter  than  its  hind  legs,  which  gives  it  a very  peculiar 
gait.  Its  forefeet  are  armed  with  long,  strong  claws,  with  which  it  digs 
its  burrow,  which  is  usually  made  in  light  soil.  It  also  often  makes  its 
home  in  some  crevice  in  rocks,  or  even  takes  possession  of  an  abandoned 
woodchuck’s  hole;  or  trusting  to  its  immunity  from  danger,  makes  its 
home  under  the  bam.  In  the  fall,  it  becomes  very  fat,  and  during  the 
early  part  of  winter,  hibernates  within  its  den;  it  comes  out  during  the 
thaws  of  winter  and  early  spring. 

The  young  skunks  appear  in  May;  they  are  born  in  an  enlarged  portion 
of  the  burrow,  where  a nice  bed  of  grass  and  leaves  is  made  for  them;  the 
skunk  is  scrupulously  neat  about  its  own  nest.  The  young  skunks  are 
very  active,  and  interesting  to  watch,  when  playing  together  like  kittens. 

The  skunk  belongs  to  the  same  family  as  the  mink  and  weasel,  which 
also  give  off  a disagreeable  odor  when  angry.  The  fetid  material  which 
is  the  skunk’s  defence,  is  contained  in  two  capsules  under  the  root  of  the 
tail.  These  little  capsules  are  not  larger  than  peas,  and  the  quantity  of 
liquid  forced  from  them  in  a discharge  is  scarcely  more  than  a large  drop; 
yet  it  will  permeate  the  atmosphere  with  its  odor  for  a distance  of  a mile. 
The  fact  that  this  discharge  is  so  disagreeable  to  all  other  animals,  has  had 
a retarding  influence  upon 
the  skunk’s  intelligence.  It 
has  not  been  obliged  to  rely 
upon  its  cunning  to  escape  its 
enemies,  and  has  therefore 
never  developed  either  fear 
or  cleverness.  It  marches 
abroad  without  haste,  confi- 
dent that  every  creature 
which  sees  it  will  give  it  plenty 
of  room.  It  is  a night 
prowler,  although  it  is  not 
averse  to  a daytime  prome- 
nade. The  white  upon  its  fur 
gives  warning  at  night,  that 
here  is  an  animal  which  had 
best  be  left  alone.  This  im- 
munity from  attack  makes 
the  skunk  careless  in  learning

248  Handbook  of  Nature-Study 

wisdom  from  experience;  it  never  learns  to  avoid  a trap  or  a railway 
or  trolley  track. 

The  skunk’s  food  consists  largely  of  insects,  mice,  snakes  and  other 
small  animals.  It  also  destroys  the  eggs  and  young  of  birds  which 
nest  upon  the  ground.  It  uses  its  strong  forepaws  in  securing  its 
prey.  Dr.  Merriam,  who  made  pets  of  young  skunks  after  removing 
their  scent  capsules,  found  them  very  interesting.  He  says  of  one 
which  was  named  “Meph”:  “We  used  to  walk  through -the  woods 
to  a large  meadow  that  abounded  in  grasshoppers.  Here,  Meph  would 
fairly  revel  in  his  favorite  food,  and  it  was  rich  sport  to  watch  his 
manoeuvres.  When  a grasshopper  jumped,  he  jumped,  and  I have  seen 
him  with  as  many  as  three  in  his  mouth  and  two  under  his  fore-paws  at 
the  same  time.” 

The  only  injury  which  the  skunk  is  likely  to  do  to  the  farmers,  is  the 
raiding  of  the  hens’  nests,  and  this  can  be  obviated  by  properly  housing 
the  poultry.  On  the  other  hand,  the  skunk  is  of  great  use  in  destroying 
injurious  insects  and  mice.  Often  when  skunks  burrow  beneath  barns, 
they  completely  rid  the  place  of  mice.  Skunk  fur  is  very  valuable  and  is 
sold  under  the  name  of  Alaskan  sable.  The  skunk  takes  short  steps,  and 
goes  so  slowly  that  it  makes  a double  track,  the  imprints  being  very  close 
together.  The  foot  makes  a longer  track  than  that  of  the  cat,  as  the 
skunk  is  plantigrade;  that  is,  it  walks  upon  its  palms  and  heels  as  well  as 
its  toes.

LESSON  LX  . 

The  Skunk 

Leading  thought — The  skunk  has  depended  so  long  upon  protecting 
itself  from  its  enemies  by  its  disagreeable  odor,  that  it  has  become  stupid 
in  this  respect,  and  seems  never  to  be  able  to  learn  to  keep  off  of  railroad 
tracks.  It  is  a very  beneficial  animal  to  the  farmer  because  its  food  con- 
sists so  largely  of  injurious  insects  and  rodents. 

Method — The  questions  should  be  given  the  pupils  and  they  should 
answer  them  from  personal  observations  or  inquiries. 

Observations — 1.  How  large  is  a skunk?  Describe  its  fur.  Where 
does  the  black  and  white  occur  in  the  fur?  Of  what  use  is  the  white  to 
the  skunk  ? Is  the  fur  valuable  ? What  is  its  commercial  name  ? 

2.  What  is  the  shape  of  the  skunk’s  head?  The  general  shape  of  the 
body?  The  tail?  Are  the  front  legs  longer  or  shorter  than  the  hind  legs ? 
Describe  the  front  feet.  For  what  are  they  used? 

3 . Where  and  how  does  the  skunk  make  its  nest  ? Does  it  sleep  like 
a woodchuck  during  the  winter?  What  is  its  food?  How  does  it  catch 
its  prey?  Does  it  hunt  for  its  food  during  the  day  or  the  night?  Does

the  skunk  ever  hurry?  Is  it  afraid?  How  does  it  protect  itself  from  its 
enemies?  Do  you  think  that  the  skunk’s  freedom  from  fear  has  rendered 
the  animal  less  intelligent  ? ( 

4.  At  what  time  do  the  skunk  kittens  appear?  Have  you  ever  seen 
little  skunks  playing  ? If  so,  describe  their  antics.  How  is  the  nest  made 
soft  for  the  young  ones? 

5.  How  does  the  skunk  benefit  farmers?  Does  it  ever  do  them  any 
injury?  Do  you  think  that  it  does  more  good  than  harm? 

6.  Describe  the  skunk’s  track  as  follows:  How  many  toes  show  in 

the  track?  Does  the  palm  or  heel  show?  Are  the  tracks  near  together? 
Do  they  form  a single  or  a double  line?

I 


Saw  a little  skunk  coming  up  the  river  bank  in  the  woods  at  the  white  oak,  a funny 
little  fellow,  about  six  inches  long  and  nearly  as  broad.  It  faced  me  and  actually  com- 
pelled me  to  retreat  before  it  for  five  minutes.  Perhaps  I was  between  it  and  its  hole. 
Its  broad  black  tail,  tipped  with  white,  was  erect  like  a kitten's.  It  had  what  Looked  like 
a broad  white  band  drawn  tight  across  its  forehand  or  top-head,  from  which  two  lines  of 
white  ran  down,  one  on  each  side  of  its  back,  and  there  was  a narrow  white  line  down  its 
snout.  It  raised  its  back,  sometimes  ran  a few  feet  forward,  sometimes  backward,  and 
repeatedly  turned  its  tail  to  me,  prepared  to  discharge  its  fluid,  like  the  old  ones.  Such 
was  its  instinct,  and  all  the  while  it  kept  up  a fine  grunting  like  a little  pig  or  a red 
squirrel. — Henry  Thoreau. 


Few  animals  are  so  silent  as  the  skunk.  Zoological  works  contain  no  information 
as  to  its  voice,  and  the  essayists  rarely  mention  it  except  by  implication.  Mr.  Bur- 
roughs says:  “ The  most  silent  creature  known  to  me,  he  makes  no  sound,  so  far  as  I 

have  observed,  save  a diffuse,  impatient  noise,  like  that  produced  by  beating  your  hand 
with  a whisk-broom,  when  the  farm-dog  has  discovered  his  retreat  in  the  stone  fence." 
Rowland  Robinson  tells  us  that:  “ The  voiceless  creature  sometimes  frightens  the 

belated  farm-boy,  whom  he  curiously  follows  with  a mysterious  hollow  beating  of  his  feet 
upon  the  ground."  Thoreau,  as  has  been  mentioned,  heard  one  keep  .up  a “ fine 
grunting,  like  a little  pig  or  a squirrel;"  but  he  seems  to  have  misunderstood  altogether  a 
singular  loud  patting  sound  heard  repeatedly  on  the  frozen  ground  under  the  wall,  which 
he  also  listened  to,  for  he  thought  it  “ had  to  do  with  getting  its  food,  patting  the  earth  to 
get  the  insects  or  worms."  Probably  he  would  have  omitted  this  guess  if  he  could  have 
edited  his  diary  instead  of  leaving  that  to  be  done  after  his  death.  The  patting  is  evi- 
dently merely  a nervous  sign  of  impatience  or  apprehension,  similar  to  the  well-known 
stamping  with  the  hind  feet  indulged  in  by  rabbits,  in  this  case  probably  a menace  like  a 
doubling  of  the  fists,  as  the  hind  legs,  with  which  they  kick,  are  their  only  weapons. 

' The  skunk,  then,  is  not  voiceless,  but  its  voice  is  weak  and  querulous,  and  it  is  rarely  if 
ever  heard  except  in  the  expression  of  anger. 

— Ernest  Ingersol  in  “Wild  Neighbors.”

THE  RACCOON 
Teacher's  Story 

)NE  other  of  our  little  brothers  of  the  forest, 
has  such  a mischievous  countenance  as  the 
coon.  The  black  patch  across  the  face 
and  surrounding  the  eyes,  like  large  goggles, 
and  the  black  line  extending  from  the  long, 
inquisitive  nose  directly  up  the  forehead  give 
the  coon’s  face  an  anxious  expression;  and 
the  keenness  of  the  big,  beady,  black  eyes 
and  the  alert,  “sassy”  looking,  broadly 
triangular  ears,  convince  one  that  the  anxiety 
depicted  in  the  face  is  anxiety  lest  something 
that  should  not  be  done  be  left  undone ; and 
I am  sure  that  anyone  who  has  had  experience  with  pet  coons  will  aver 
that  their  acts  do  not  belie  their  looks. 

What  country  child, 
wandering  by  the  brook  and  7 
watching  its  turbulence  in 
early  spring,  has  not  viewed 
with  awe,  a footprint  on  the 
muddy  banks  looking  as  if  it 
were  made  by  the  foot  of  a^ 
very  little  baby.  The  first 
one  I ever  saw,  I promptly 
concluded  was  made  by  the

foot  of  a brook  fairy.  However,  the  coon  is  no  fairy;  it  is  a rather 
heavy,  logy  animal  and,  like  the  bear  and  skunk,  is  plantigrade,  walking 
on  the  entire  foot  instead  of  on  the  toes,  like  a cat  or  dog.  The  hind  foot 
is  long,  with  a well-marked  heel,  and  five  comparatively  short  toes,  giv- 
ing it  a remarkable  resemblance  to  a human  foot.  The  front  foot  is 
smaller  and  looks  like  a wide,  little  hand,  with  four  long  fingers  and  a 
rather  short  thumb.  The  claws  are  strong  and  sharp.  The  soles 
of  the  feet  and  the  palms  of  the  hands  look  as  if  they  were  covered 
with  black  kid,  while  the  feet  above  and  the  backs  of  the  hands  are 
covered  with  short  fur.  Coon  tracks  are  likely  to  be  found  during  the 
first  thawing  days  of  winter,  along  some  stream  or  the  borders  of 
swamps,  often  following  the  path  made  by  cattle.  The  full-length  track 
is  about  2 inches  long;  as  the  coon  puts  the  hind  foot  in  the  track  made  by 
the  front  foot  on  the  same  side,  only  the  print  of  the  hind  feet  is  left, 
showing  plainly  five  toe  prints  and  the  heel.  The  tracks  may  vary 
from  one-half  inch  to  one  foot  or  more  apart,  depending  on  how 
fast  the  animal  is  going;  when  it  runs  it  goes  on  its  toes,  but  when  walking 
sets  the  heel  down ; the  tracks  are  not  in  so  straight  a line  as  those  made 
by  the  cat.  Sometimes  it  goes  at  a slow  jump,  when  the  prints  of  the 
hind  feet  are  paired,  and  between  and  behind  them  are  the  prints  of  the 
two  front  feet. 

The  coon  is  covered  with  long,  rather  coarse  hair,  so  long  as  to  almost 
drag  when  the  animal  is  walking;  it  really  has  two  different  kinds  of 
hair,  the  long,  coarse,  gray  hair,  blackened  at  the  tips,  covering  the  fine, 
short,  grayish  or  brownish  under  coat.  The  very  handsome  bushy  tail  is 
ringed  with  black  and  gray. 

The  raccoon  feeds  on  almost  anything  eatable,  except  herbage.  It  has 
a special  predilection  for  com  in  the  milk  stage  and,  in  attaining  this 
sweet  and  toothsome  luxury,  it  strips  down  the  husks  and  often  breaks 
the  plant,  doing  much  damage.  It  is  also  fond  of  poultry  and  often  raids 
hen  houses;  it  also  destroys  birds’  nests  and  the  young,  thus  damaging 
the  farmer  by  killing  both  domestic  and  wild  birds.  It  is  especially  fond 
of  fish  and  is  an  adept  at  sitting  on  the  shore  and  catching  them  with  its 
hands;  it  likes  turtle  eggs,  crayfish  and  snakes;  it  haunts  the  bayous  of 
the  Gulf  Coast  for  the  oysters  which  grow  there;  it  is  also  a skillful  frog 
catcher.  Although  fond  of  animal  diet,  it  is  also  fond  of  fruit,  especially 
of  berries  and  wild  grapes. 

It  usually  chooses  for  a nest  a hollow  tree  or  a cavern  in  a ledge  near  a 
stream,  because  of  its  liking  for  water  creatures;  and  also  because  of  its 
strange  habit  of  washing  its  meat  before  eating  it.  I have  watched  a pet 
coon  performing  this  act;  he  would  take  a piece  of  meat  in  his  hands, 
dump  it  into  the  pan  of  drinking  water  and  souse  it  up  and  down  a few 
times;  then  he  would  get  into  the  pan  with  his  splay  feet  and  roll  the  meat 
beneath  and  between  them,  meanwhile  looking  quite  unconcernedly  at  his 
surroundings,  as  if  washing  the  meat  were  an  act  too  mechanical  to  occupy 
his  mind.  After  the  meat  had  become  soaked  until  white  and  flabby,  he 
would  take  it  in  his  hands  and  hang  on  to  it  with  a tight  grip  while  he 
pulled  off  pieces  with  his  teeth;  or  sometimes  he  would  hold  it  with  his 
feet,  and  use  hands  as  well  as  teeth  in  tearing  it  apart.  The  coon’s  teeth 
are  very  much  like  those  of  the  cat,  having  long,  sharp  tushes  or  canines, 
and  sharp,  wedge-shaped  grinding  teeth,  which  cut  as  well  as  grind. 
After  eating,  the  pet  coon  always  washed  his  feet  by  splashing  them  in 
the  pan. 


252 


Handbook  of  Nature-Study 


It  is  a funny  sight  to  watch  a coon  arrange  itself  for  a nap,  on  a branch 
or  in  the  fork  of  a tree , it  adapts  its  fat  body  to  the  unevenness  of  the  bed 
with  apparent  comfort ; it  then  tucks  its  nose  down  between  its  paws  and 
curls  its  tail  about  itself,  making  a huge,  furry  ball.  In  all  probability, 
the  rings  of  gray  and  black  on  the  tail,  serve  as  protective  color  to  the 
animal  sleeping  in  a tree  during  the  daytime,  when  sunshine  and  shadow 
glance  down  between  the  leaves  with  ever-changing  light.  The  coon 
spends  much  of  its  days  asleep  in  some  such  situation,  and  comes  forth  at 
night  to  seek  its  food. 

In  the  fall,  the  coon  lays  on  fat  enough  to  last  it  during  its  winter  sleep. 
Usually  several  inhabit  the  same  nest  in  winter,  lying  curled  up  together 
in  a hollow  tree,  and  remaining  dormant  all  winter  except  when  awakened 
by  the  warmth  of  a thaw.  They  then  may  come  forth  to  see  what  is 
happening,  but  return  shortly  to  wait  until  March  or  April;  then  they 
issue  to  hunt  for  the  scant  food,  and  are  so  lean  and  weak  that  they  fall 
easy  prey  to  their  enemies. 

The  young  are  bom  in  April  and  May;  there  are  from  three  to  six  in  a 
litter;  they  are  blind  and  helpless  at  first,  and  are  cared  for  carefully 
by  their  parents,  the  family  remaining  together  for  a year,  until  the  young 
are  fully  grown.  If  removed  from  their  parents  the  young  ones  cry 
pitifully,  almost  like  babies.  The  cry  or  whistle  of  the  fully  grown  coon 
is  anything  but  a happy  sound,  and  is  quite  impossible  to  describe.  I 
have  been  awakened  by  it  many  a night  in  camp,  and  it  always  sounded 
strange,  taking  on  each  time  new  quavers  and  whimperings.  As  a cry, 
it  is  first  cousin  to  that  of  the  screech-owl. 

The  stories  of  pet  coons  are  many.  I knew  one  which,  chained  in  a 
yard,  would  lie  curled  up  near  its  post  looking  like  an  innocent  stone 
except  for  one  eye  kept  watchfully  open.  Soon  a hen,  filled  with  curiosity 
would  come  warily  near,  looking  longingly  at  remains  of  food  in  the  pan ; 
the  coon  made  no  move  until  the  disarmed  biddy  came  close  to  the  pan. 
Then,  there  was  a scramble  and  a squawk  and  with  astonishing  celerity 
he  would  wring  her  neck  and  strip  off  her  feathers.  Another  pet  coon 
was  allowed  to  range  over  the  house  at  will,  and  finally  had  to  be  sent 
away  because  he  had  learned  to  open  every  door  in  the  house,  including 
cupboard  doors,  and  could  also  open  boxes  and  drawers  left  unlocked; 
and  I have  always  believed  he  could  have  learned  to  unlock  drawers  if  he 
had  been  given  the  key.  All  coons  are  very  curious,  and  one  way  of 
trapping  them  is  to  suspend  above  the  trap  a bit  of  bright  tin;  in  solving 
this  glittering  mystery,  traps  are  forgotten. 

LESSON  LXI 
The  Raccoon 

Leading  thought — The  raccoon  lives  in  hollow  trees  or  caves  along 
the  banks  of  streams.  It  sleeps  during  the  day  and  seeks  its  food  at 
night.  It  sleeps  during  the  winter. 

Method — If  there  are  raccoons  in  the  vicinity,  ask  the  older  boys  to 
look  for  their  tracks  rear  the  streams  and  to  describe  them  very  care- 
fully to  the  class.  The  ideal  method  of  studying  the  animal,  is  to 
have  a pet  coon  where  the  children  may  watch  at  leisure  its  enter- 
taining and  funny  performances.  If  this  is  impossible,  then  follow  the

less  desirable  method  of  having  the  pupils  read  about  the  habits  of  the 
coon  and  thus  arouse  their  interest  and  open  their  eyes,  so  that  they 
may  make  observations  of  their  own  when  opportunity  offers.  I would 
suggest  the  following  topics  for  oral  or  written  work  in  English : 

“How  and  Where  Coons  Live  and  What  They  Do;”  “The  Autobio- 
graphy of  a Coon  One  Year  Old;”  “The  Queer  Antics  of  Pet  Coons;” 
“Stories  of  the  Coon’s  Relative,  the  Bear.” 


Treed. 


Observations — 1.  Where  have  you  found  raccoon  tracks?  How  do 
they  differ  from  those  of  fox  or  dog?  How  far  are  the  footprints  apart? 
Can  you  see  the  heel  and  toe  prints?  Do  you  see  the  tracks  of  all  four 
feet  ? Are  the  tracks  in  a straight  line  like  those  of  the  cat  ? What  is  the 
size  of  the  track,  the  length,  the  breadth? 

2.  What  do  coons  eat  and  how  do  they  get  their  food?  Which  of  our 
crops  are  they  likely  to  damage?  What  other  damage  do  they  do? 
Have  you  ever  heard  coons  cry  or  whistle  during  August  nights  in  the 
cornfields?

3.  Why  do  raccoons  like  to  live  near  the  water?  W hat  do  they  find 
of  interest  there?  How  do  they  prepare  their  meat  before  eating  it? 
How  does  a coon  handle  its  meat  while  eating  it  ? 

4.  What  kind  of  fur  has  the  coon?  Why  does  it  need  such  a heavy 
covering?  Describe  the  color  of  the  fur.  Describe  the  tail.  Of  what  use 
is  such  a large  and  bushy  tail  to  this  animal? 

5.  Describe  the  coon’s  face.  How  is  it  marked ? What  is  its  expres- 
sion? Describe  the  eyes  and  ears.  The  nose.  Has  it  teeth  resembling 
those  of  the  cat  and  dog? 

6.  Describe  the  coon’s  feet.  How  many  toes  on  the  front  feet? 
How  many  on  the  hind  feet?  How  does  this  differ  from  the  cat  and  dog? 
How  do  the  front  and  hind  feet  differ  in  appearance  ? Can  both  be  used 
as  hands? 

7.  How  do  coons  arrange  themselves  for  a nap  in  a tree?  How  do 
they  cover  the  head?  How  is  the  tail  used?  Do  you  think  this  bushy 
tail  used  in  this  way  would  help  to  keep  the  animal  warm  in  winter? 
Do  coons  sleep  most  daytimes  or  nights? 

8.  At  what  time  of  year  are  coons  fattest?  Leanest?  Why?  Do 
they  ever  come  out  of  their  nests  in  winter?  Do  they  live  together  or 
singly  in  winter? 

9.  At  what  time  of  year  are  the  young  coons  born?  Do  you  know 
how  they  look  when  they  are  young?  How  are  they  cared  for  by  their 
parents  ? 

10.  Are  the  coon’s  movements  slow  or  fast?  What  large  animal  is 
a near  relative  of  the  coon?

THE  WOLF 


HE  study  of  the  wolf  should  precede  the  lessons 
on  the  fox  and  the  dog.  After  becoming 
familiar  with  the  habits  of  wolves,  the  pupils 
will  be  much  better  able  to  understand  the 
nature  of  the  dog  and  its  life  as  a wild  animal. 
In  most  localities,  the  study  of  the  wolf  must, 
of  course,  be  a matter  of  reading,  unless  the 
pupils  have  an  opportunity  to  study  the 
animal  in  traveling  manageries  or  in  zoo- 
logical gardens.  However,  in  all  the  gov- 
ernment preserves,  the  timber  wolf  has 
multiplied  to  such  an  extent,  that  it  may 
become  a factor  in  the  lives  of  many  people  in  the  United  States.  This 
wolf  ranged  in  packs  over  New  York  State  a hundred  years  ago,  but 
was  finally  practically  exterminated  in  most  of  the  eastern  forests,  except 
in  remote  and  mountainous  localities.  A glance  at  Bulletin  72  by 
Vernon  Bailey,  published  by  the  U.  S.  Department  of  Agriculture, 
Forest  Service,  is  a revelation  of  the  success  of  the  timber  wolf,  in 
coming  back  to  his  own,  as  soon  as  the  forest  preserves  furnished 
plenty  of  game,  and  forbade  hunters.  Timber  wolves  are  returning  of 
late  years  to  Western  Maine  and  Northern  New  Hampshire;  Northern 
Michigan  and  Wisconsin  have  them  in  greater  numbers ; some  have  also 
been  killed  in  the  Apalachian  Mountains  of  Tennessee,  Virginia  and  West 
Virginia,  but  their  stronghold  is  in  the  great  Rocky  Mountain  Region  and 
the  Northwestern  Sierras,  from  which  they  have  never  been  driven. 

It  might  be  well  to  begin  this  lesson  on  the  wolf  with  a talk  about  the 
gray  wolves  which 
our  ancestors  had  to 
contend  with,  and 
also  with  stories  of 
the  coyote  or  prairie 
wolf  which  has 
learned  to  adapt 
itself  to  civilization 
and  flourishes  in  the 
regions  west  of  the 
Rocky  Mountains, 
despite  men  and 
dogs.  Literature  is 
rich  in  wolf  stories. 

Although  Kipling’s 
famous  M o w g 1 i 
Stories  belong  t o 
the  realm  of  fiction, 
yet  they  contain 
interesting  accounts 
of  the  habits  of  the 
wolves  of  India,  and 

are  based  upon  the  Gray  Wolf 

hunter’s  and  track-

er’s  knowledge  of  these  animals.  We  have  many  thrillingly  interesting 
stories  in  our  own  literature  which  deal  with  our  native  wolves.  The 
following  are  among  the  best : 

“Lobo”  in  Wild  Animals  I Have  Known;  “Tito”  in  Lives  of  the 
Hunted;  “Bad  Lands  Billy  and  the  Winnipeg  Wolf”  in  Animal  Heroes 
all  by  Thompson  Seton;  “The  Passing  of  Black  Whelps”  in  Watchers  of 
the  Trail  by  Roberts;  Northern  Trails  by  Long;  “Pico,  Coyote”  by  Coolidge 
in  True  Tales  of  Birds  and  Beasts. 

For  more  serious  accounts  of  the  wolves  see  American  Animals, 
p.  277;  The  “Hound  of  the  Plains, ”in  Wild  Neighbors,  and  page  188  in 
the  Life  of  Animals,  both  by  Ingersoll.  “The  Coyote”  by  Bret  Harte  and 
“The  Law  of  the  Pack”  in  the  Second  Jungle  Book  bring  the  wolf 
into  poetry. 

From  some  or  all  of  these  stories,  the  pupils  should  get  informa- 
tion about  the  habits  of  the  wolves.  This  information  should  be  in- 
corporated in  an  essay  or  an  oral  exercise  and  should  cover  the  following 
points:  Where  do  the  wolves  live?  On  what  do  they  feed?  How 

do  they  get  their  prey?  Do  they  hunt  alone  or  in  packs?  How  do  they 
call  to  each  other?  Description  of  the  den  where  the  young  are  reared.

THE  FOX 


Teacher's  Story 

O WE  not  always,  on  a clear  morning  of  winter,  feel  a 
thrill  that  must  have  something  primitive  in  its 
quality,  at  seeing  certain  tracks  in  the  snow  that 
somehow  suggest  wildness  and  freedom!  Such 
is  the  track  of  the  fox.  Although  it  is  somewhat 
dike  that  of  a small  dog  yet  it  is  very  different. 
The  fox  has  longer  legs  than  most  dogs  of  his 
weight,  and  there  is  more  of  freedom  in  his  track 
and  more  of  strength  and  agility  expressed  in  it. 
His  gait  is  usually  an  easy  lope;  this  places  the 
imprint  of  three  feet  in  a line,  one  ahead  of 
another,  but  the  fourth  is  off  a little  at  one  side,  as  if  to  keep  the  balance. 

The  fox  lives  in  a den  or  burrow.  The  only  fox  home  which  I ever 
saw,  was  a rather  deep  cave  beneath  the  roots  of  a stump,  and  there  was 
no  burrow  or  retreat  beyond  it.  However,  foxes  often  select  woodchuck 
burrows,  or  make  burrows  of  their  own,  and  if  they  are  caught  within, 
they  can  dig  rapidly,  as  many  a hunter  can  attest.  The  mother  usually 
selects  an  open  place  for  a den  for  the  young  foxes ; often  an  open  field  or 
side-hill  is  chosen  for  this.  The  den  is  carpeted  with  grass  and  is  a very 
comfortable  place  for  the  fox  puppies.  The  den  of  the  father  fox  is 
usually  not  far  away. 

The  face  of  the  red  fox  shows  plainly  why  he  has  been  able  to  cope  with 
man,  and  thrive  despite  and  because  of  him.  If  ever  a face  showed 
cunning,  it  is  his.  Its  pointed,  slender  nose  gives  it  an  expression  of 
extreme  cleverness,  while  the  width  of  the  head  between  the  upstanding, 
triangular  ears  gives  room  for  a brain  of  power.  In  color  the  fox  is  russet- 
red,  the  hind  quarters  being  grayish.  The  legs  are  black  outside  and 
white  inside;  the  throat  is  white,  and  the  broad,  triangular  ears  are  tipped 
with  black.  The  glory  of  the  fox  is  his  “brush,”  as  the  beautiful,  bushy 
tail  is  called.  This  is  red,  with  black  toward  the  end  and  white-tipped. 
This  tail  is  not  merely  for  beauty,  for  it  affords  the  fox  warmth  during  the 
winter,  as  any  one  may  see  who  has  observed  the  way  it  is  wrapped

around  the  sleeping  animal.  But  this  bushy  tail  is  a disadvantage,  if  it 
becomes  bedraggled  and  heavy  with  snow  and  sleet,  when  the  hounds  are 
giving  close  chase  to  its  owner.  The  silver  fox  and  the  black  fox  are  the 
same  species  as  the  red  fox. 

The  fox  is  an  inveterate  hunter  of  the  animals  of  the  field;  meadow 
mice,  rabbits,  woodchucks,  frogs,  snakes  and  grasshoppers,  are  all 
acceptable  food;  he  is  also  destructive  of  birds.  His  fondness  for  the 
latter  has  given  him  a bad  reputation  with  the  farmer  because  of  his 
attacks  on  poultry.  Not  only  will  he  raid  hen-roosts  if  he  can  force 
entrance,  but  he  catches  many  fowls  in  the  summer  when  they  are  wander- 
ing through  the  fields.  The  way  he  carries  the  heavy  burden  of  his 
larger  prey  shows  his  cleverness:  He  slings  a hen  or  a goose  over  his 

shoulders,  keeping  the  head  in  his  mouth  to  steady  the  burden.  Mr. 
Cram  says,  in  American  Animals: 

“Yet,  although  the  farmer  and  the  fox  are  such  inveterate  enemies, 
they  manage  to  benefit  each  other  in  a great  many  ways  quite  uninten- 
tionally. The  fox  destroys  numberless  field  mice  and  woodchucks  for  the 
farmer  and  in  return  the  farmer  supplies  him  with  poultry,  and  builds 
convenient  bridges  over  streams  and  wet  places,  which  the  fox  crosses 
oftener  than  the  farmer,  for  he  is  as  sensitive  as  a cat  about  getting  his 
feet  wet.  On  the  whole,  I am  inclined  to  believe  that  the  fox  gets  the 
best  part  of  the  exchange,  for,  while  the  farmer  shoots  at  him  on  every 
occasion,  and  hunts  him  with  dogs  in  the  winter,  he  has  cleared  the  land 
of  wolves  and  panthers,  so  that  foxes  are  probably  safer  than  before  any 
land  was  ploughed.” 

The  bark  of  the  fox  is  a high,  sharp  yelp,  more  like  the  bark  of  the 
coyote  than  of  the  dog.  There  is  no  doubt  a considerable  range  of 
meaning  in  the  fox’s  language,  of  which  we  are  ignorant.  He  growls 
when  angry,  and  when  pleased  he  smiles  like  a dog  and  wags  his  beautiful 
tail. 

Many  are  the  wiles  of  the  fox  to  head  off  dogs  following  his  track : he 

often  retraces  his  own 
steps  for  a few  yards 
and  then  makes  a long 
sidewise  jump ; the 
dogs  go  on,  up  to  the 
end  of  the  trail 
pocket,  and  try  in 
vain  to  get  the  scent 
from  that  point. 
Sometimes  he  walks 
along  the  top  rails  of 
fences  or  takes  the 
high  and  dry  ridges 
where  the  scent  will 
not  remain;  he  often 
follows  roads  and 
beaten  paths  and  also 
goes  around  and 
around  in  the  midst 
of  a herd  of  cattle, 
so  that  his  scent  is 
hidden ; he  crosses

streams  on  logs  and  invents  various  other  devices  too  numerous  and 
intricate  to  describe.  When  chased  by  dogs,  he  naturally  runs  in  a 
circle,  probably  so  as  not  to  be  too  far  from  home  If  there  are  young 
ones  in  the  den,  the  father  fox  leads  the  hounds  far  away,  in  the  next 
county,  if  possible.  Perhaps  one  of  the  most  clever  tricks  of  the  fox,  is 
to  make  friends  with  the  dogs.  I have  known  of  two  instances  where 
a dog  and  fox  were  daily  companions  and  playfellows. 

The  young  foxes  are  bom  in  the  spring.  They  are  black  at  first  and 
are  fascinating  little  creatures,  being  exceedingly  playful  and  active. 
Their  parents  are  very  devoted  to  them,  and  during  all  their  puppyhood, 
the  mother  fox  is  a menace  to  the  poultry  of  the  region,  because  the 
necessity  is  upon  her  of  feeding  her  rapidly  growing  litter. 

In  my  opinion,  the  best  story  of  animal  fiction  is  “Red  Fox”  by 
Roberts.  Like  all  good  fiction,  it  is  based  upon  facts  and  it  presents  a 
wholesome  picture  of  the  life  of  the  successful  fox.  “The  Silver  Fox”  by 
Thompson  Seton  is  another  interesting  and  delightful  story.  Although 
the  Nights  with  Uncle  Remus  could  scarcely  be  called  nature  stories, 
yet  they  are  interesting  in  showing  how  the  fox  has  become  a part  of 
folk-lore.

LESSON  LXI1 
The  Fox 

Leading  thought — The  red  fox  is  so  clever  that  it  has 
been  able,  in  many  parts  of  our  country,  to  maintain 
itself  despite  dogs  and  men. 

Method — This  lesson  is  likely  to  be  given  largely  from 
hearsay  or  reading.  However,  if  the  school  is  in  a rural 
district,  there  will  be  plenty  of  hunters’  stories  afloat, 
from  which  may  be  elicited  facts  concerning  the  cunning 
and  cleverness  of  the  red  fox.  In  such  places  there  is 
also  the  opportunity  in  winter  to  study  fox  tracks  upon 
the  snow.  The  lesson  may  well  be  given  when  there  are 
fox  tracks  for  observation.  The  close  relationship 
between  foxes  and  dogs  should  be  emphasized. 

Observations  and  reading — 1.  Describe  the  fox’s  track.  How  does  it 
differ  from  the  track  of  a small  dog  ? 

2 . Where  does  the  fox  make  its  home  ? Describe  the  den.  Describe 
the  den  in  which  the  young  foxes  live  ? 

3.  Describe  the  red  fox,  its  color  and  form  as  completely  as  you  can. 
What  is  the  expression  of  its  face  ? What  is  there  peculiar  about  its  tail  ? 
What  is  the  use  of  this  great  bushy  tail  in  the  winter  ? 

4.  What  is  the  food  of  the  fox?  How  does  it  get  its  food?  Is  it  a 
day  or  a night  hunter  ? How  does  the  fox  benefit  the  farmer  ? How  does 
it  injure  him?  How  does  the  fox  carry  home  its  heavy  game,  such  as  a 
goose  or  a hen  ?

5.  Have  you  ever  heard  the  fox  bark?  Did  it  sound  like  the  bark 
of  a dog?  How  does  the  fox  express  anger?  Pleasure? 

6.  When  chased  by  dogs,  in  what 
direction  does  the  fox  run?  Describe 
all  of  the  tricks  which  you  know  by 
which  the  fox  throws  the  dog  off  the 
scent. 

7.  When  are  the  young  foxes 
bom?  How  many  in  a litter?  What 
color  are  they?  How  do  they  play 
with  each  other?  How  do  they  learn 
to  hunt?

DOGS 

Teacher's  Story 

VC  onty  to-day  but  in  ancient  days,  before  the  dawn 

of  history,  the  dog  was  the  companion  of  man. 

V % V\  Whether  the  wild  species  from  whence  he  sprang, 

I \ I \ was  wolf  or  jackal  or  some  other  similar  animal,  we 

I \ do  no^  know,  but  we  do  know  that  many  types  of 

■ dogs  have  been  tamed  independently  by  savages, 

V a r in  the  region  where  their  untamed  relatives  run 

wild.  As  the  whelps  of  wolves,  jackals  and  foxes 
are  all  easily  tamed,  and  are  most  interesting  little 
creatures,  we  can  understand  how  they  became  companions  to  the  children 
of  the  savage  and  barbarous  peoples  who  hunted  them. 

In  the  earliest  records  of  cave  dwellers,  in  the  picture  writing  of  the 
ancient  Egyptians  and  of  other  ancient  peoples,  we  find  record  of  the 
presence  and  value  of  the  dog.  But  man,  in  historical  times,  has  been 
able  to  evolve  breeds  that  vary  more  in  form  than  do  the  wild  species  of 
the  present.  There  are  200  distinct  breeds  of  dogs  known  to-day,  and 
many  of  these  have  been  bred  for  special  purposes.  The  paleontologists, 
moreover,  assure  us  that  there  has  been  a decided  advance  in  the  size  and 
quality  of  the  dog’s  brain  since  the  days  of  his  savagery ; thus,  he  has  been 
the  companion  of  man’s  civilization  also.  It  is  not,  therefore,  to  be 
wondered  at  that  the  dog  is  now  the  most  companionable,  and  has  the 
most  human  qualities  and  intelligence  of  all  our  domesticated  animals. 

Dogs  run  down  their  prey ; it  is  a necessity,  therefore,  that  they  be 
equipped  with  legs  that  are  long,  strong  and  muscular.  The  cat,  which 
jumps  for  her  prey,  has  much  more  delicate  legs  but  has  powerful  hips  to 
enable  her  to  leap.  The  dog’s  feet  are  much  more  heavily  padded  than 
those  of  the  cat,  because  in  running,  he  must  not  stop  to  save  his  feet. 
Hounds  often  return  from  a chase  with  bleeding  feet,  despite  the  heavy 
pads,  but  the  wounds  are  usually  cuts  between  the  toes.  The  claws  are 
heavy  and  are  not  retractile;  thus,  they  afford  a protection  to  the  feet 
when  running,  and  they  are  also  used  for  digging  out  game  which  burrows 
into  the  ground.  They  are  not  used  for  grasping  prey  like  those  of  the  cat 
and  are  used  only  incidentally  in  fighting,  while  the  cat’s  claws  are  the 
most  important  weapons  in  her  armory.  It  is  an  interesting  fact  that 
Newfoundland  dogs,  which  are  such  famous  swimmers,  have  their  toes 
somewhat  webbed. 


262  Handbook  of  Nature-Study 

The  dog’s  body  is  long,  lean,  and 
very  muscular,  a fat  dog  being 
usually  pampered  and  old.  The 
coat  is  of  hair  and  is  not  of  fine  fur 
like  that  of  the  cat.  It  is  of  inter- 
est to  note  that  the  Newfoundland 
dog  has  an  inner  coat  of  fine  hair 
• comparable  to  that  of  the  mink  or 
muskrat.  When  a dog  is  running, 
his  body  is  extended  to  its  fullest 
length;  in  fact,  it  seems  to  “lie 
flat,”  the  outstretched  legs  height- 
ening the  effect  of  extreme  muscular 
effort  of  forward  movement.  A 
dog  is  master  of  several  gaits;  he 
can  run,  walk,  trot,  bound  and 
crawl. 

The  iris  of  the  dog’s  eye  is 
usually  of  a beautiful  brown,  al- 
though this  varies  with  breeds;  in 
puppies,  the  iris  is  usually  blue.  The  pupil  is  round  like  our  own;  and 
dogs  cannot  see  well  in  the  dark  like  the  cat,  but  in  daylight  they  have 
keen  sight.  The  nose  is  so 
much  more  efficient  than  the 
eyes,  that  it  is  on  the  sense  of 
smell  the  dog  depends  for  fol- 
lowing his  prey  and  for  recog- 
nizing friend  and  foe.  The 
damp,  soft  skin  that  covers 
the  nose,  has  in  its  dampness 
the  conditions  for  carrying 
the  scent  to  the  wide  nostrils ; 
these  are  situated  at  the  most 
forward  part  of  the  face,  and 
thus  may  be  lifted  in  any 
direction  to  receive  the  mar- 
velous impressions,  so  com- 
pletely beyond  our  compre- 
hension. Think  of  being  able 
to  scent  the  track  of  a fox 
made  several  hours  previously.  Bird  dog. 

Not  only  to  scent  it,  but  to 

follow  by  scent  for  many  miles  without  ever  having  a glimpse  of  the  fleeing 
foe!  In  fact,  while  running,  the  dog’s  attention  seems  to  be  focused 
entirely  upon  the  sense  of  smell,  for  I have  seen  hounds  pass  within  a few 
rods  to  the  windward  of  the  fox  they  were  chasing,  without  observing  him 
at  all.  When  the  nose  of  any  of  the  moist-nosed  beasts,  such  as  cattle 
and  dogs,  becomes  dry  it  is  a sign  of  illness. 

A light  fall  of  damp  snow  gives  the  dog  the  best  conditions  for  follow- 
ing a track  by  scent  and  a hound,  when  on  the  trail,  will  run  until  ex- 
hausted. There  are  many  authentic  observations  which  show  that 
hounds  have  followed  a fox  for  twenty-four  hours  without  food,  and 
probably  with  little  rest.

The  dog’s  weapons  for  battle,  like  those  of  the  wolf,  are  his  tushes: 
with  these,  he  holds  and  tears  his  prey;  with  them,  he  seizes  the  wood- 
chuck or  other  small  animal  through  the  back  and  shakes  its  life  out.  In 
fighting  a larger  animal,  the  dog  leaps  against  it  and  often  incidentally 
tears  its  flesh  with  his  strong  claws ; but  he  does  not  strike  a blow  with  his 
foot  like  the  cat,  nor  can  he  hold  his  quarry  with  it. 

Dog’s  teeth  are  especially  fitted  for  their  work. 

The  incisors  are  small  and  sharp;  the  canine  teeth 
or  tushes  are  very  long,  but  there  are  bare  spaces  on 
the  jaws  so  that  they  are  able  to  cross  past  each 
other;  the  molar  teeth  are  not  fitted  for  grinding, 
like  the  teeth  of  a cow,  but  are  especially  fitted  for 
cutting,  as.  may  be  noted  if  we  watch  the  way  a dog 
gnaws  bones,  first  gnawing  with  the  back  teeth  on 
one  side  and  then  on  the  other.  In  fact,  a dog 
does  not  seem  to  need  to  chew  anything,  but  simply 
needs  to  cut  his  meat  in  small  enough  pieces  so  that 
he  can  gulp  them  down  without  chewing.  His 
powers  of  digesting  unchewed  food  are  something  Bulldog. 

that  the  hustling  American  may  well  envy. 

Of  all  domestic  animals,  the  dog  is  most  humanly  understandable  in 
expressing  emotions.  If  delighted,  he  leaps  about  giving  ecstatic 
little  barks  and  squeals,  his  tail  in  the  air  and  his  eyes  full  of  happy  an- 


264 


Handbook  of  N atur e-Study 


ticipation.  If  he  wishes  to  be  friendly,  he  looks  at  us  interestedly,  comes 
ever  to  smell  of  us  in  order  to  assure  himself  whether  he  has  ever  met  us 
before,  and  then  wags  his  tail  as  a sign  of  good  faith.  If  he  wishes  to 
show  affection,  he  leaps  upon  us  and  licks  our  face  or  hands  with  his 
soft,  deft  tongue  and  follows  us  jealously.  When  he  stands  at  attention, 
he  holds  his  tail  stiff  in  the  air,  and  looks  up  with  one  ear  lifted  as  if 
to  say,  “Well,  what’s  doing?”  When  angry,  he  growls  and  shows  his 
teeth  and  the  tail  is  held  rigidly  out  behind,  as  if  to  convince  us  that  it 
is  really  a continuation  of  his  backbone.  When  afraid,  he  whines  and 
lies  flat  upon  his  belly,  often  looking  beseechingly  up  toward  his  master  as 
if  begging  not  to  be  punished;  or  he  crawls  away  out  of  sight.  When 
ashamed,  he  drops  his  tail  between  his  legs  and  with  drooping  head  and 
sidewise  glance  slinks  away.  When  excited,  he  barks  and  every  bark 
expresses  high  nervous  tension. 

Almost  all  dogs  that  chase  their  prey,  bark  when  so  doing,  which 
would  seem  at  first  sight  to  be  a foolish  thing  to  do,  in  that  it  reveals  their 
whereabouts  to  their  victims  and  also  adds  an  incentive  to  flight.  But  it 
must  be  borne  in  mind  that  dogs  are  descended  from  wolves,  which 

naturally  hunt  in  packs  and 
do  not  stalk  their  prey.  The 
baying  of  the  hound  is  a most 
common  example  of  the  habit, 
and  as  we  listen  we  can  under- 
stand how,  by  following  this 
sound,  the  pack  is  kept  to- 
gether. Almost  all  breeds  of 
dogs  have  an  acute  sense  of 
hearing.  When  a dog  bays 
at  the  moon  or  howls  when  he 
hears  music,  it  is  simply  a 
reversion  to  the  wild  habit  of 
howling  to  call  together  the 
pack  or  in  answer  “to  the 
music  of  the  pack.”  It  is 
interesting  that  our  music, 
which  is  the  flower  of  our 
civilization,  should  awaken 
the  sleeping  ancestral  traits 
in  the  canine  breast.  But 
perhaps  that,  too,  is  why  we 
in  us  the  strong,  primitive 
emotions,  and  for  the  time,  enables  us  to  free  ourselves  from  all  conven- 
tional shackles  and  trammels.

LESSON  LXIII 
DOGS 

Leading  thought — The  dog  is  a domesticated  descendant  of  wolf-like 
animals  and  has  retained  certain  of  the  habj.ts  and  characteristics  of  his 
ancestors. 

Method — For  the  observation  lesson  it  would  be  well  to  have  at  hand,  a 
well-disposed  dog  which  would  not  object  to  being  handled;  a collie  or  a 
hound  would  be  preferable.  Many  of  the  questions  should  be  given  to 
the  pupils  to  answer  from  observations  at  home,  and  the  lesson  should  be 
built  upon  the  experience  of  the  pupils  with  dogs. 

Observations — -1 . Why  are  the  legs  of  the  dog  long  and  strong  in  pro- 
portion to  the  body  compared  with  those  of  the  cat? 

2.  Compare  the  feet  of  the  cat  with  those  of  the  dog  and  note  which 
has  the  heavier  pads.  Why  is  this  of  use  to  each? 

3.  Which  has  the  stronger  and  heavier  claws,  the  dog  or  the  cat? 
Can  the  dog  retract  his  claws  so  that  they  are  not  visible,  as  does  the  cat? 
Of  what  use  is  this  arrangement  to  the  dog?  Are  the  front  feet  just  like 
the  hind  feet?  How  many  toe  impressions  show  in  the  track  of  the  dog? 

4.  What  is  the  general  characteristic  of  the  body  of  the  dog?  Is  it 
soft  like  that  of  the  cat,  or  lean  and  muscular?  What  is  the  difference 
between  the  hair  covering  of  the  dog  and  cat?  What  is  the  attitude  of 
the  dog  when  running  fast  ? How  many  kinds  of  gaits  has  he  ? 

5.  In  general,  how  do  the  eyes  of  the  dog  differ  from  those  of  the 
cat  ? Does  he  rely  as  much  upon  his  eyes  for  finding  his  prey  as  does  the 
cat?  Can  a dog  see  in  the  dark?  What  is  the  color  of  the  dog’s  eyes? 

6.  Study  the  ear  of  the  dog ; is  it  covered  ? Is  this  outer  ear  movable, 
is  it  a flap,  or  is  it  cornucopia  shaped?  How  is  this  flap  used  when  the 
dog  is  listening?  Roll  a sheet  of  paper  into  a flaring  tube  and  place  the

Handbook  of  Nature-Study 


small  end  upon  your  own  ear,  and  note  if  it  helps  you  to  hear  better  the 
sounds  in  the  direction  toward  which  the  tube  opens?  Note  how  the 
hound  lifts  his  long  earlaps,  so  as  to  make  a tube  for  conveying  sounds  to 
his  inner  ear.  Do  you  think  that  dogs  can  hear  well  ?

The  dog  that  pulled  four  hundred  fifty  pounds  five  hundred 
miles  through  the  White  Horse  Pass  in  the  winter

7 . What  is  the 
position  of  the  nose  in 
the  dog’s  face?  Of 
what  use  is  this? 
Describe  the 'nostrils; 
are  they  placed  on 
the  foremost  point  of 
the  face?  What  is 
the  condition  of  the 
skin  that  surrounds 
them?  How  does  this 
condition  of  the  nose 
aid  the  dog?  What 
other  animals  have  it  ? 
Does  the  dog  recog- 
nize his  friends  or 
become  acquainted 
with  stralngers  by 
means  of  his  sight  or 
of  his  powers  of  smell- 
ing? 

8.  How  long  after 
a fox  or  rabbit  has 

passed  can  a hound  follow  the  track?  Does  he  follow  it  by  sight  or  by 
smell?  What  are  the  conditions  most  favorable  for  retaining  the  scent? 
The  most  unfavorable?  How  long  will  a hound  follow  a fox  trail  without 
stopping  for  rest  or  food?  Do  you  think  the  dog  is  your  superior  in 
ability  to  smell  ?

and  claws  when  fighting?  What  are  his  especially  strong  weapons? 
Describe  a dog’s  teeth  and  explain  the  reason  for  the  bare  spaces  on  the 
jaw  next  to  the  tushes.  Does  the  dog  use 
his  tushes  when  chewing?  What  teeth  does 
he  use  when  gnawing  a bone?  Make  a 
diagram  of  the  arrangement  of  the  dog’s 
teeth. 

10.  How  by  action,  voice,  and  especially 

by  the  movement  of  the  tail  does  the  dog  ex- 
press the  following  emotions:  Delight, 

friendliness,  affection,  attention,  anger,  fear, 
shame,  excitement?  How  does  he  act  when 
chasing  his  prey?  Why  do  wolves  and  dogs 
bark  when  following  the  trail  ? Do  you  think 
of  a reason  why  dogs  often  howl  at  night  or 
when  listening  to  music?  What  should  we 
feed  to  our  pet  dogs?  What  should  we  do  to 
make  them  comfortable  in  other  ways?

THE  CAT 
Teacher's  Story 

F all  people,  the  writer  should  regard  the  cat  sym- 
pathetically, for  when  she  was  a baby  of  five 
months  she  was  adopted  by  a cat.  My  self- 
elected  foster-mother  was  Jenny,  a handsome  black 
and  white  cat,  which  at  that  time  lost  her  first 
litter  of  kittens,  through  the  attack  of  a savage  cat 
from  the  woods.  She  was  as  Rachel  crying  for  her 
children,  when  she  seemed  suddenly  to  compre- 
hend that  I,  although  larger  than  she,  was  an 
infant.  She  haunted  my  cradle,  trying  to  give 
me  milk  from  her  own  breasts;  and  later  she 
brought  half-killed  mice  and  placed  them  enticingly  in  my  cradle,  coaxing 
me  to  play  with  them,  a performance  which  pleased  me  much  more  than 
it  did  my  real  mother.  Jenny  always  came  to  comfort  me  when  I cried, 
rubbing  against  me,  purring  loudly,  and  licking  me  with  her  tongue  in  a 
way  to  drive  mad  the  modern  mother,  wise  as  to  the  sources  of  children’s 
internal  parasites.  This  maternal  attitude  toward  me  lasted  as  long  as 
Jenny  lived,  which  was  until  I was  nine  years  old.  Never  during  those 
years  did  I lift  my  voice  in  wailing,  that  she  did  not  come  to  comfort 
me;  and  even  to-day  I can  remember  how  great  that  comfort  was, 
especially  when  my  naughtiness  was  the  cause  of  my  weeping,  and  when, 
therefore,  I felt  that  the  whole  world,  except  Jenny,  was  against  me.

Jenny  was  a cat  of  remarkable  intelligence  and  was  very  obedient  and 
useful.  Coming  down  the  kitchen  stairs  one  day,  she  played  with  the 
latch  and  someone  hearing  her,  opened  the  door.  She  did  this  several 
times,  when  one  day  she  chanced  to  push  down  the  latch,  and  thus  opened 
the  door  herself.  After  that,  she  always  opened  it  herself.  A little  later, 
she  tried  the  trick  on  other  doors,  and  soon  succeeded  in  opening  all  the 
latched  doors  in  the  house,  by  thrusting  one  front  leg  through  the  handle, 
and  thus  supporting  her  weight  and  pressing  down  with  the  foot  of  the 
other  on  the  thumb-piece  of  the  latch.  I remember,  guests  were  greatly 
astonished  to  see  her  coming  thus  swinging  into  the  sitting-room.  Later 
she  tried  the  latches  from  the  other  side,  jumping  up  and  trying  to  lift  the 
hook;  but  now,  her  weight  was  thrown  against  the  wrong  side  of  the  door 
for  opening,  and  she  soon  ceased  this  futile  waste  of  energy;  but  for 
several  years,  she  let  herself  into  all  the  rooms  in  this  clever  manner,  and 
taught  a few  of  her  bright  kittens  to  do  the  same. 

A pet  cat  enjoys  long  conversations  with  favored  members  of  the 
household.  She  will  sit  in  front  of  her  mistress  and  mew,  with  every 
appearance  of  answering  the  questions  addressed  her;  and  since  the  cat 
and  the  mistress  each  knows  her  own  part  of  the  conversation,  it  is  per- 
haps more  typical  of  society  chatter  than  we  might  like  to  confess.  Of 
our  language,  the  cat  learns  to  understand  the  call  to  food,  its  own  name, 
“scat,”  and  “No,  No,”  probably  inferring  the  meaning  of  the  latter  from 
the  tone  of  voice.  On  the  other  hand,  we  understand  when  it  asks  to  go 
out,  and  its  polite  recognition  to  the  one  who  opens  the  door.  I knew  one 
cat  which  invariably  thanked  us  when  we  let  him  in  as  well  as  out. 
When  the  cat  is  hungry,  it  mews  pleadingly;  when  happy  in  front  of  the 
fire,  it  looks  at  us  sleepily  out  of  half-closed  eyes  and  gives  a short  mew 
expressive  of  affection  and  content;  or  it  purrs,  a noise  which  we  do  not 
know  how  to  imitate  and  which  expresses  perfectly  the  happiness  of  inti- 
mate companionship.  When  frightened  the  cat  yowls,  and  when  hurt 
squalls  shrilly;  when  fighting,  it  is  like  a savage  warrior  in  that  it  howls  a 
war-song  in  blood-curdling  strains,  punctuated  with  a spitting  expressive 
of  fear  and  contempt;  and  unfortunately,  its  love  song  is  scarcely  less 
agonizing  to  the  listener.  The  cat’s  whole  body  enters  into  the  expression 
of  its  emotions.  When  feeling  affectionate  toward  its  mistress,  it  rubs 
against  her  gown,  with  tail  erect,  and  vibrating  with  a purr  which  seems 
fundamental.  When  angry,  it  lays  its  ears  back  and  lashes  its  tail  back 
and  forth,  the  latter  being  a sign  of  excitement;  when  frightened,  its  hair 
stands  on  end,  especially  the  hair  of  the  tail,  making  that  expressive 
appendage  twice  its  natural  size;  when  caught  in  disobedience,  the  cat 
lets  its  tail  droop,  and  when  running  lifts  it  in 
a curve. 

While  we  feed  cats  milk  and  scraps  from 
our  own  table,  they  have  never  become  entirely 
civilized  in  their  tastes.  They  always  catch 
mice  and  other  small  animals  and  prove  pesti- 
ferous in  destroying  birds.  Jenny  was  wont 
to  bring  her  quarry,  as  an  offering,  to  the  front 
steps  of  our  home  every  night;  one  morning 
we  found  seven  mice,  a cotton-tail  rabbit  and 
two  snakes,  which  represented  her  night’s 
catch.  The  cat  never  chases  its  prey  like  the 
dog.  It  discovers  the  haunts  of  its  victims,

and  then  lies  in  ambush,  flattened  out  as  still  as  a statue  and  all  its  feet 
beneath  it,  ready  to  make  the  spring.  The  weight  of  the  body  is  a factor 
which  enters  in  the  blow  with  which  the  cat  strikes  down  its  victim,  and 
thus  stuns  and  which  it  later  kills  by  gripping  the  throat  with  the  strong 
tushes.  She  carries  her  victims  as  she  does  her  kittens,  by  the  back. 

The  cat’s  legs  are  not  long  compared  with  the  body,  and  it  runs  with  a 
leaping  gallop ; the  upper  legs  are  armed  with  powerful  muscles.  It  walks 
on  the  padded  toes,  five  on  the  front  feet  and  four  of  the  hind  feet.  The 
cat  needs  its  claws  to  be  sharp  and  hooked,  in  order  to  seize  and  hold  its 
prey,  so  they  are  kept  safely  sheathed  when  not  thus  used.  If  the  claws 
struck  the  earth  during  walking,  as  do  the  dog’s,  they  would  soon  become 
dulled.  When  sharpening  its  claws  it  reaches  high  up  against  a tree  or 
post,  and  strikes  them  into  the  wood  with  a downward  scratch;  this  act 
is  probably  more  for  exercising  the  muscles  which  control  the  claws  than 
for  sharpening  them. 

The  cat’s  track  is  in  a single  line  as  if  it  had  only  two  feet,  one  set 
directly  ahead  of  the  other.  It  accomplishes  this  by  setting  its  hind  feet 
exactly  in  the  tracks  made  by  the  front  feet.  The  cat  can  easily  leap 
upward,  landing  on  a window-sill  five  feet  from  the  ground.  The  jump  is 
made  with  the  hind  legs  and  the  alighting  is  done  silently  on  the  front 
feet. 

Cats’  eyes  are  fitted  for  seeing  in  the  dark;  in  the  daytime  the  pupil  is 
simply  a narrow,  up  and  down  slit;  under  excitement,  and  at  night,  the 
pupil  covers  almost  the  entire  eye.  At  the  back  of  the  eye  is  a reflecting 
surface,  which  catches  such  dim  light  as  there  is,  and  by  reflecting  it 
enables  the  cat  to  use  it  twice.  It  is  this  reflected  light,  which  gives  the 
peculiar  green  glare  to  the  eyes  of  all  the  cats  when  seen  in  the  dark. 
Some  night-flying  moths  have  a like  arrangement  for  utilizing  the  light, 
and  their  eyes  glow  like  living  coals.  Of 
course,  since  the  cat  is  a night  hunter,  this 
power  of  multiplying  the  rays  of  light  is  of 
great  use.  The  iris  of  the  eye  is  usually 
yellow,  but  in  kittens  it  may  be  blue  or  green. 

The  cat’s  teeth  are  pecularily  fitted  for 
its  needs.  The  six  doll-like  incisors  of  the 
upper  and  lower  jaw  are  merely  for  scraping 
meat  from  bones.  The  two  great  tushes, 
or  canines,  on  each  jaw,  with  a bare  place 
behind  so  that  they  pass  each  other  freely,  are 
sharp  and  hooked,  and  are  for  seizing  and 
carrying  prey.  The  cat  is  able  to  open  its 
mouth  as  wide  as  a right  angle,  in  order  to 
better  hold  and  carry  prey.  The  back  teeth, 
or  molars,  are  four  on  each  side  in  the  upper 
jaw  and  three,  below.  They  are  sharp-edged 
wedges  made  for  cutting  meat  fine  enough,  so 
that  it  may  be  swallowed. 

The  tongue  is  covered  with  sharp  papillae 
directed  backwards,  also  used  for  rasping 
juices  from  meat.  The  cat’s  nose  is  moist, 
“ Folks  are  so  tiresome .”  and  her  sense  of  smell  very  keen,  as  is  also  her 

sense  of  hearing.  The  ears  rise  like  two  hollow  half-cones  on  either

side  of  the  head  and  are  filled  with  sensitive  hairs;  they  ordinarily  open 
forward,  but  are  capable  of  movement.  The  cat’s  whiskers  consist  of 
from  twenty-five  to  thirty  long  hairs  set  in  four  lines,  above  and  at  the 
sides  of  the  mouth ; they  are  connected  with  sensitive  nerves  and  are 
therefore  true  feelers.  The  cat’s  fur  is  very  fine  and  thick,  and  is  also 
sensitive;  as  can  readily  be  proved,  by  trying  to  stroke  it  the  wrong 
way.  While  the  wild  cats  have  gray  or  tawny  fur,  variously  mottled 
or  shaded,  the  more  striking  colors  we  see  in  the  domestic  cats  are  the 
result  of  man’s  breeding. 

Cats  are  very  cleanly  in  their  habits.  Puss  always  washes  her  face 
directly  after  eating,  using  one  paw  for  a wash-cloth  and  licking  it  clean 
after  she  rubs  her  face.  She  cleans  her  fur  with  her  rough  tongue  and 
also  by  biting;  and  she  promptly  buries  objectionable  matter.  The 
mother  cat  is  very  attentive 
to  the  cleanliness  of  her  kit- 
tens, licking  them  clean  from 
nose  tip  to  tail  tip.  The  ways 
of  the  mother  cat  with  her 
kittens  do  much  to  sustain 
the  assertions  of  Mr.  Seton 
and  Mr.  Long  that  young 
animals  are  trained  and  edu- 
cated by  their  parents.  The 
cat  brings  half-dazed  mice  to 
her  kittens,  that  they  may 
learn  to  follow  and  catch  them 
with  their  own  little  claws. 

When  she  punishes  them,  she 
cuffs  the  ears  by  holding  one 
side  of  the  kitten’s  head  firm 
with  the  claws  of  one  foot, 
while  she  lays  on  the  blows 
with  the  other.  She  carries  her  “ Interested T* 

kittens  by  the  nape  of  the  neck, 

never  hurting  them.  She  takes  them  into  the  field  when  they  are  old 
enough,  and  shows  them  the  haunts  of  mice,  and  does  many  things  for 
their  education  and  welfare.  The  kittens  meantime  train  themselves  to 
ag  ility  and  dexterity,  by  playing  rough  and  tumble  with  each  other,  and 
by  chasing  every  small  moving  object,  even  to  their  own  tails. 

The  cat  loves  warmth  and  finds  her  place  beneath  the  stove  or  at  the 
hearthside.  She  likes  some  people,  and  dislikes  others,  for  no  reason  we 
can  detect.  She  can  be  educated  to  be  friendly  with  dogs  and  with 
birds.  In  feeding  her,  we  should  give  her  plenty  of  sweet  milk,  some 
cooked  meat  and  fish  of  which  she  is  very  fond;  and  we  should  keep  a 
bundle  of  catnip  to  make  her  happy,  for  even  the  larger  cats  of  the  wilder- 
ness seem  to  have  a passionate  liking  for  this  herb.  The  cat  laps  milk 
with  her  rough  tongue,  and  when  eating  meat,  she  turns  the  head  this 
way  and  that,  to  cut  the  tough  muscle  with  her  back  teeth.

Cats  Should  be  Trained  to  Leave  Birds  Alone 

Every  owner  of  a cat  owes  it  to  the  world  to  train  puss  to  leave  birds 
alone.  If  this  training  is  begun  during  kittenhood,  by  switching  the 
culprit  every  time  it  even  looks  at  a bird,  it  will  soon  learn  to  leave  them 

severefy  alone.  I have  tried 
this  many  times,  and  I know 
it  is  efficacious,  if  the  cat  is 
intelligent.  We  have  never 
had  a cat  whose  early  training 
we  controlled,  that  could  ever 
be  induced  to  even  watch 
birds.  If  a cat  is  not  thus 
trained  as  a kitten,  it  is  likely 
to  be  always  treacherous  in 
this  respect.  But  in  case  any 
one  has  a valuable  cat  which 
is  given  to  catching  birds,  I 
strongly  advise  the  following 
treatment  which  has  been 
proved  practicable  by  a friend 
of  mine.  When  a cat  has  made  the  catch,  take  the  bird  away  and 
sprinkle  it  with  red  pepper,  and  then  give  it  back.  One  Such  treatment 
as  this  resulted  in  making  one  cat,  which  was  an  inveterate  bird 
hunter,  run  and  hide  every  time  he  saw  a bird  thereafter.  Any  persons 
taking  cats  with  them  to  their  summer  homes,  and  abandoning  them 
there  to  prey  upon  the  birds  of  the  vicinity,  and  to  become  poor,  half- 
starved,  wild  creatures,  ought  to  be  arrested  and  fined.  It  is  not 
only  cruelty  to  the  cats,  but  it  is  positive  injury,  and  damage  to  the  com- 
munity, because  of  the  slaughter  of  beneficial  birds  which  it  entails. 


This  cat  has  been  trained  to  be  friendly 
with  birds. 


LESSON  LXIV 
The  Cat 

Leading  thought — The  cat  was  made  a domestic  animal  before  man 
wrote  histories.  It  gets  prey  by  springing  from  ambush  and  is  fitted  by 
form  of  body  and  teeth  to  do  this.  It  naturally  hunts  at  night  and  has 
eyes  fitted  to  see  in  the  dark. 

Method — This  lesson  may  be  used  in  primary  grades  by  asking  a few 
questions  at  a time  and  allowing  the  children  to  make  their  observations  on 
their  own  kittens  at  home,  or  a kitten  may  be  brought  to  school  for  this 
purpose.  The  upper  grade  work  consists  of  reading  and  retelling  or  writ- 
ing exciting  stories  of  the  great,  wild,  savage  cats,  like  the  tiger,  lion, 
leopard,  lynx  and  panther. 

Observations- — 1.  How  much  of  Pussy’s  language  do  you  understand? 
What  does  she  say  when  she  wishes  you  to  open  the  door  for  her?  How 
does  she  ask  for  something  to  eat  ? What  does  she  say  when  she  feels  like 
conversing  with  you ? How  does  she  cry  when  hurt?  When  frightened? 
What  noise  does  she  make  when  fighting?  When  calling  other  cats? 
What  are  her  feelings  when  she  purrs?  When  she  spits?  How  many 
things  which  you  say  does  she  understand?

2.  How  else  than  by  voice  does  she  express  affection,  pleasure  and 
anger?  When  she  carries  her  tail  straight  up  in  the  air  is  she  in  a pleasant 
mood?  When  her  tail  “bristles  up”  how  does  she  feel?  What  is  it 
a sign  of,  when  she  lashes  her  tail  back  and  forth? 

3.  What  do  you  feed  to  cats?  What  do  they  catch  for  themselves? 
What  do  the  cats  that  are  wild  live  upon?  How  does  the  cat  help  us? 
How  does  she  injure  us? 

4.  How  does  a cat  catch  her  prey?  Does  she  track  mice  by  the  scent? 
Does  she  catch  them  by  running  after  them  as  a dog  does?  Describe  how 
she  lies  in  ambush.  How  does  she  hold  the  mouse  as  she  pounces  upon  it  ? 
How  does  she  carry  it  home  to  her  kittens  ? 

5.  Study  the  cat’s  paws  to  see  how  she  holds  her  prey.  Where  are 
the  sharp  claws ? Are  they  always  in  sight  like  a dog’s?  Does  she  touch 
them  to  the  ground  when  she  walks?  Which  walks  the  more  silently. 


Amicable  advances. 


a dog  or  a cat?  Why?  Describe  the  cat’s  foot,  including  the  toe-pads. 
Are  there  as  many  toes  on  the  hind  feet  as  on  the  front  feet?  What  kind 
of  a track  does  the  cat  make  in  the  snow?  How  does  she  set  her  feet  to 
make  such  a track  ? How  does  she  sharpen  her  claws  ? How  does  she  use 
her  claws  for  climbing ? How  far  have  you  ever  seen  a cat  jump?  Does 
she  use  her  front  or  her  hind  feet  in  making  the  jump  ? On  which  feet  does 
she  alight?  Does  she  make  much  noise  when  she  alights? 

6.  What  is  there  peculiar  about  a cat’s  eyes?  What  is  their  color? 
What  is  the  color  of  kittens’  eyes?  What  is  the  shape  of  the  pupil  in  day- 
light ? In  the  dark  ? Describe  the  inner  lid  which  comes  from  the  comer 
of  the  eye. 

7.  How  many  teeth  has  Puss?  What  is  the  use  of  the  long  tushes? 
Why  is  there  a bare  space  behind  these?  What  does  she  use  her  little 
front  teeth  for?  Does  she  use  her  back  teeth  for  chewing  or  for  cutting 
meat  ? 

8.  How  many  whiskers  has  she?  How  long  are  they?  What  is 
their  use?  Do  you  think  that  puss  has  a keen  sense  of  smell?  Why  do 


274 


Handbook  of  Nature-Study 


you  think  so?  Do  you  think  she  has  a keen  sense  of  hearing?  How  do 
the  shape  and  position  of  the  ears  help  in  listening?  In  what  position  are 
the  ears  when  puss  is  angry? 

9.  How  many  colors  do  you  find  in  our  domestic  cats.  What  is  the 
color  of  wild  cats  ? Why  would  it  not  be  beneficial  to  the  wild-cat  to  have 
as  striking  colors  as  our  tame  cats  ? Compare  the  fur  of  the  cat  with  the 
hair  of  the  dog.  How  do  they  differ?  If  a cat  chased  her  prey  like  the 
dog  do  you  think  her  fur  would  be  a too  warm  covering? 

10.  Describe  how  the  cat  washes  her  face.  How  does  she  clean  her 
fur?  How  does  her  rough  tongue  help  in  this?  How  does  the  mother 
cat  wash  her  kittens  ? 

1 1 . How  does  a little  kitten  look  when  a day  or  two  old?  How  long 
before  its  eyes  open  ? How  does  the  cat  carry  her  kittens  ? How  does  a 
kitten  act  when  it  is  being  carried  ? How  does  the  mother  cat  punish  her 
kittens  ? How  does  she  teach  them  to  catch  mice  ? How  do  kittens  play  ? 
How  does  the  exercise  they  get  in  playing  fit  them  to  become  hunters  ?

THE  GOAT 
Teacher's  Story 

Little  do  we  in  America  realize  the  close  companionship  that  has  ex- 
isted in  older  countries,  from  time  immemorial,  between  goats  and  people. 
This  association  began  when  man  was  a nomad,  and  took  with  him  in  his 
wanderings,  his  flocks,  of  which  goats  formed  the  larger  part.  He  then 
drank  their  milk,  ate  their  flesh,  wove  their  hair  into  raiment,  or  made 
cloth  of  their  pelts,  and  used  their  skins  for  water  bags.  Among  peoples 
of  the  East  all  these  uses  continue  to  the  present  day.  In  the  streets  of 
Cairo,  old  Arabs  may  be  seen  with  goat  skins  filled  with  water  upon  their 
backs;  and  in  any  city  of  Western  Asia  or  Southern  Europe,  flocks  of 
goats  are  driven  along  the  streets  to  be  milked  in  sight  of  the  consumer. 

In  order  to  understand  the  goat’s  peculiarities  of  form  and  habit,  we 
should  consider  it  as  a wild  animal,  living  upon  the  mountain  heights  amid 
rocks  and  snow  and  scant  vegetation.  It  is  marvelously  sure-footed  and 
when  on  its  native  mountains,  it  can  climb  the  sharpest  crags  and  leap 
chasms.  This  peculiarity  has  been  seized  upon  by  showmen  who  often 
exhibit  goats  which  walk  on  the  tight  rope  with  ease,  and  even  turn 
themselves  upon  it  without  falling.  The  instinct  for  climbing  still 
lingers  in  the  domestic  breeds,  and  in  the  country  the  goat  may  be  seen  on 
top  of  stone  piles  or  other  objects,  while  in  city  suburbs,  its  form  may  be 
discerned  on  the  roofs  of  shanties  and  stables. 

It  is  a common  saying  that  a goat  will  eat  anything,  and  much  sport 
is  made  of  this  peculiarity.  This  fact  has  more  meaning  for  us  when  we 
realize  that  wild  goats  live  in  high  altitudes,  where  there  is  little  plant 
life,  and  are  therefore,  obliged  to  find  sustenance  on  lichens,  moss  and  such 
scant  vegetation  as  they  can  find.

Handbook  of  Nature-Study 


The  goat  is  closely  allied  to  the  sheep,  differing  from  it  in  only  a few 
particulars ; its  horns  rise  from  the  forehead  curving  over  backward  and 
do  not  form  a spiral  like  those  of  the  rafli;  its  covering  is  usually  of  hair, 
and  the  male  has  a beard  from  which  we  get  the  name  goatee ; the  ‘goat 
has  no  gland  between  the  toes,  and  it  does  have  a rank  and  disagreeable 
odor.  In  a wild  state,  it  usually  lives  a little  higher  up  the  mountains 
than  do  the  sheep,  and  it  is  a far  more  intelligent  animal.  Mary  Austin 
says:  “Goats  lead  naturally  by  reason  of  a quicker  instinct,  forage  more 

freely  and  can  find  water  on  their  own  account,  and  give  voice  in  case  of 
alarm.  Goat  leaders  exhibit  jealousy  of  their  rights  to  be  first  over  the 
stepping-stones  or  to  walk  the  teetering  log  bridges  at  the  roaring  creeks.” 
On  the  great  plains,  it  is  a common  usage  to  place  a few  goats  in  a flock  of 
sheep,  because  of  the  greater  sagacity  of  these  animals  as  leaders,  and  also 
as  defenders  in  case  of  attack. 

Goats’  teeth  are  arranged  for  cropping  herbage  and  especially  for 

browsing.  There  are  six  molar  teeth  on 
each  side  of  each  jaw;  there  are  eight 
lower  incisors  and  none  above.  The 
goat’s  sense  of  smell  is  very  acute;  the 
ears  are  movable  and  the  sense  of  hear-

ingis  keen;  the  eyes  are  full  and  very  intelligent;  the  horns  are  some- 
what  flattened  and  angular  and  often  knobbed  somewhat  in  front,  and 
curve  backward  above  the  neck;  they  are,  however,  very  efficient  as 
weapons  of  defence.  The  legs  are  strong,  though  not  large,  and  are  well 
fitted  for  leaping  and  running.  The  feet  have  two  hoofs,  that  is,  the 
animal  walks  upon  two  toe-nails.  There  are  two  smaller  toes  behind 


Mammal  Study

and  above  the  hoofs.  The  goat  can  run  with  great  rapidity.  The  tail 
of  the  goat  is  short  like  that  of  the  deer,  and  does  not  need  to  be  ampu- 
tated like  that  of  the  sheep.  Although  the  normal  covering  of  the  goat  is 
hair,  there  are  some  species  which  have  a more  or  less  woolly  coat. 
When  angry  the  goat  shakes  its  head,  and  defends  itself  by  butting 
with  the  head,  also  by  striking  with  the  horns,  which  are  very  sharp. 
Goats  are  very  tractable  and  make  affectionate  pets  when  treated  with 
kindness;  they  display  far  more  affection  for  their  owner  than  do  sheep. 

Our  famous  Rocky  Mountain  goat,  although  it  belongs  rather  to  the 
antelope  family,  is  a large  animal,  and  is  the  special  prize  of  the  hunter; 
however,  it  still  holds  its  own  in  the  high  mountains  of  the  Rocky  and

Cascade  Ranges.  Both  sexes  have  slender  black  horns,  white  hair,  and 
black  feet,  eyes  and  nose.  Owen  Wister  says  of  this  animal:  “He  is 
white,  all  white,  and  shaggy,  and  twice  as  large  as  any  goat  you  ever  saw. 
His  white  hair  hangs  long  all  over  him  like  a Spitz  dog’s  or  an  Angora 
cat’s;  and  against  its  shaggy  white  mass  the  blackness  of  his  hoofs  and 
horns,  and  nose  looks  particularly  black.  His  legs  are  thick,  his  neck  is 
thick,  everything  about  him  is  thick,  save  only  his  thin  black  horns. 
They’re  generally  about  six  (often  more  than  nine)  inches  long,  they 
spread  very  slightly,  and  they  curve  slightly  backward.  At  their  base 
they  are  a little  rough,  but  as  they  rise  they  become  cylindrically  smooth 
and  taper  to  an  ugly  point.  His  hoofs  are  heavy,  broad  and  blunt.  The 
female  is  lighter  than  the  male,  and  with  horns  more  slender,  a trifle. 
And  (to  return  to  the  question  of  diet)  we  visited  the  pasture  where  the 
herd  (of  thirty- five)  had  been,  and  found  no  signs  of  grass  growing  or  grass 
eaten;  there  was  no  grass  on  that  mountain.  The  only  edible  substance

was  a moss,  tufted,  stiff  and  dry  to  the  touch.  I also  learned  that  the  goat 
is  safe  from  predatory  animals.  With  his  impenetrable  hide  and  his 
disemboweling  horns  he  is  left  by  the  wolves  and  mountain  lions  respect- 
fully alone.”  (See  American  Animals,  p.  57 ; Camp  Fires  of  a Naturalist, 
chapters  VIII  and  XIII). 

Milch  Goats — Many  breeds  of  these  have  been  developed,  and  the 
highest  type  is,  perhaps,  found  in  Switzerland.  The  Swiss  farmers  have 
found  the  goat  particularly  adapted  to  their  high  mountains  and  have  used 
it  extensively;  thus,  goats  developed  in  the  Saane  and  Toggenburg  val- 
leys have  a world- wide  reputation.  Above  these  valleys  the  high  moun- 
tains are  covered  with  perpetual  snow,  and  winter  sets  in  about  Novem- 
ber. 1st,  lasting  until  the  last  of  May.  The  goats  are  kept  with  the  cows 
in  bams  and  fed  upon  hay;  but  as  soon  as  the  snow  is  gone  from  the  val- 
leys and  the  lower  foot-hills,  the  cattle  and  goats  are  sent  with  the  herders 
and  boy  assistants,  to  the  grazing  grounds.  A bell  is  put  upon  the  cow 
that  leads  the  herd  so  as  to  keep  it  together  and  the  boys,  in  their  gay 

peasant  dresses,  are  as  happy  as 
the  playful  calves  and  goats  to  get 
out  in  the  spring  sunshine.  The 
herds  follow  the  receding  snows 
up  the  mountains  until  about  mid- 
summer, when  they  reach  the 
high  places  of  scanty  vegetation; 
then  they  start  on  the  downward 
journey,  returning  to  the  home 
and  stables  about  November  1st. 
The  milk  from  goats  is  mixed  with 
that  from  cows  to  make  cheese, 
and  this  cheese  has  a wide  reputa- 
tion; some  of  the  varieties  are: 
Roquefort,  Schweitzer  and  Alten- 
burger.  Although  the  cheese  is 
excellent,  the  butter  made  from 
goat’s  milk  is  quite  inferior  to 
that  made  from  the  cow’s.  The 
milk,  when  the  animals  are  well 
taken  care  of,  is  exceedingly 
nourishing;  it  is  thought  to  be  the 
best  milk  in  the  world  for  children. 
Usually,  the  trouble  with  goat’s 
milk  is,  that  the  animals  are  not 
kept  clean  nor  is  care  taken  in 
milking.  Germany  has  produced 
many  distinct  and  excellent  breeds 
of  milch  goats;  the  Island  of 
Malta,  Spain,  England,  Ireland, 
Egypt  and  Nubia  have  each 
developed  noted  breeds.  Of  all 
these,  the  Nubias  give  the  most  milk,  sometimes  yielding  from  four  to  six 
quarts  per  day,  while  an  ordinary  goat  is  considered  fairly  good  if  it  yields 
two  quarts  per  day.

The  Mohair  Goats — There  are  two  noted  breeds  of  goats  whose  hair  is 
used  extensively  for  weaving  into  fabrics;  one  of  these  is  the  Cashmere 
and  the  other  the  Angora.  The  Cashmere  goat  has  long,  straight,  silky 
hair  for  an  outside  coat  and  has  a winter  under-coat  of  very  delicate  wool. 
There  are  not  more  than  two  or  three  ounces  of  this  wool  upon  one  goat, 
and  this  is  made  into  the  famous  Cashmere  shawls;  ten  goats  furnish 
barely  enough  of  this  wool  for  one  shawl.  The  Cashmere  goats  are  grown 
most  largely  in  Thibet,  and  the  wool  is  shipped  from  the  high  tableland  to 
the  Valley  of  Cashmere,  and  is  made  into  shawls.  It  requires  the  work  of 
several  people  for  a year  to  produce  one  of  these  famous  shawls. 

The  Angora  goat  has  a long,  silky  and  very  curly  fleece.  These  goats 
were  first  discovered  in  Angora,  a city  of  Asia  Minor  south  of  the  Black 
Sea,  and  some  200  miles  southeast  from  Constantinople.  The  Angora 
goat  is  a beautiful  and  delicate  animal,  and  furnishes  most  of  the  mohair, 
which  is  made  into  the  cloths  known  as  mohair,  alpaca,  camel’s  hair  and 
many  other  fabrics.  The  Angora  goat  has  been  introduced  into  America, 
in  California,  Texas,  Arizona,  and  to  some  extent  in  the  Middle  West.  It 
promises  to  be  a very  profitable  industry.  (See  Farmers’  Bulletin  No. 
137,  “The  Angora  Goat,”  United  States  Department  of  Agriculture.) 

The  skins  of  goats  are  used  extensively;  morocco,  gloves  and  many 
other  articles  are  made  from  them.  In  the  Orient,  the  skin  of  the  goat  is 
used  as  a bag  in  which  to  carry  water  and  wine.

LESSON  LXV 
The  Goat 

Leading  thought — Goats  are  among  our  most  interesting  domesticated 
animals,  and  their  history  is  closely  interwoven  with  the  history  of  the 
development  of  civilization.  In  Europe,  their  milk  is  made  into  cheese 
that  has  a world-wide  fame;  and  from  the  hair  of  some  of  the  species, 
beautiful  fabrics  are  woven.  The  goat  is  naturally  an  animal  of  the  high 
mountains. 

Method — A span  of  goats  harnessed  to  a cart  is  second  only  to  ponies, 
in  a child’s  estimation ; therefore,  the  beginning  of  this  lesson  may  well  be 
a span  of  goats  thus  employed.  The  lesson  should  not  be  given  unless  the 
pupils  have  an  opportunity  for  making  direct  observations  on  the  animal’s 
appearance  and  habits.  There  should  be  some  oral  and  written  work  in 
English  done  with  this  lesson.  Following  are  topics  for  such  work: 
“The  Milch  Goat  of  Switzerland,”  “How  Cashmere  Shawls  are  Made,” 
“The  Angora  Goat,”  “The  Chamois.” 

Observations — i . Do  you  think  that  goats  like  to  climb  to  high  points  ? 
Are  they  fitted  to  climb  steep,  inaccessible  places?  Can  they  jump  off 
steep  places  in  safety?  How  does  it  happen  the  goat  is  sure-footed? 
How  do  its  legs  and  feet  compare  with  those  of  the  sheep  ? 

2.  What  does  the  goat  eat?  Where  does  it  find  its  natural  food  on 
mountains  ? How  are  the  teeth  arranged  for  cutting  its  food  ? Does  a 
goat  chew  its  cud  like  a cow? 

3.  What  is  the  covering  of  the  goat?  Describe  a billy-goat’s  beard. 
Do  you  suppose  this  is  for  ornament?  For  what  is  goat’s  hair  used? 

4.  Do  you  think  the  goat  has  a keen  sense  of  sight,  of  hearing  and  of 
smell  ? Why  ? Why  did  it  need  to  be  alert  and  keen  when  it  lived  wild 
upon  the  mountains?  Do  you  think  the  goat  is  intelligent?  Give  in- 
stances of  this? 

5.  Describe  the  horns.  Do  they  differ  from  the  horns  of  the  sheep? 
How  does  a goat  fight?  Does  he  strike  head  on,  like  the  sheep,  or  side- 
wise?  How  does  he  show  anger? 

6.  What  noises  does  a goat  make?  Do  you  understand  what  they 
mean? 

7.  Describe  the  goat,  its  looks  and  actions.  Is  the  goat’s  tail  short  at 
first  or  does  it  have  to  be  cut  off  like  the  lamb’s  tail?  Where  and  how  is 
goat’s  milk  used?  What  kinds  of  cheese  are  made  from  it ? For  what  is 
its  skin  used  ? Is  its  flesh  ever  eaten  ? 

Everyone  knows  the  gayety  of  young  kids,  which  prompts  them  to  cut  the  most 
amusing  and  burlesque  capers.  The  goat  is  naturally  capricious  and  inquisitive,  and 
one  might  say  crazy  for  every  species  of  adventure.  It  positively  delights  in  perilous 
ascensions.  At  times  it  will  rear  and  threaten  you  with  its  head  and  horns,  apparently, 
with  the  worst  intentions,  whereas  it  is  usually  an  invitation  to  play.  The  bucks, 
however,  fight  violently  with  each  other;  they  seem  to  have  no  consciousness  of  the  must 
terrible  blows.  The  ewes  themselves  are  not  exempt  from  this  vice. 

They  know  very  well  whether  or  not  they  have  deserved  punishment.  Drive  them 
out  of  the  garden,  where  they  are  forbidden  to  go,  with  a whip  and  they  will  flee 
without  uttering  a sound;  but  strike  them  without  just  cause  and  they  will  send  forth 
lamentable  cries.

THE  SHEEP 


Teacher's  Story 

“ The  earliest  important  achievement  of  ovine  intelligence  is  to  know  whether  its  own 
notion  or  another's  is  most  worth  while,  and  if  the  other's,  which  one f Individual 
sheep  have  certain  qualities,  instincts,  competences,  but  in  the  man-herded  flocks  these 
are  superseded  by  something  which  I shall  call  the  flock  mind,  though  I cannot  say  very 
well  what  it  is,  except  that  it  is  less  than  the  sum  of  all  their  intelligences . This  is  why 
there  have  never  been  any  notable  changes  in  the  management  of  flocks  since  the  first 
herder  girt  himself  with  a wallet  of  sheep- skin  and  went  out  of  his  cave-dwelling  to  the 
pastures." — “The  Flock,”  by  Mary  Austin. 

Both  sheep  and  goats  are  at  home  on  mountains,  and  sheep  especially, 
thrive  best  in  cool,  dry  locations.  As  wild  animals,  they  were  Creatures 
of  the  mountain  crag  and  chasm,  although  they  frequented  more  open 
places  than  the  mountain  goats,  and  their  wool  was  developed  to  protect 
them  from  the  bitter  cold  of  high  altitudes.  They  naturally  gathered  in 
flocks,  and  sentinels  were  set  to  give  warning  of  the  approach  of  danger; 
as  soon  as  the  signal  came,  they  made  their  escape,  not  in  the  straight 
away  race  like  the  deer,  but  in  following  the  leader  over  rock,  ledge  and 
precipice  to  mountain  fastnesses  where  wolf  nor  bear  could  follow.  Thus, 
the  instinct  of  following  the  leader  blindly,  came  to  be  the  salvation  of  the 
individual  sheep. 

The  teeth  of  the  sheep  are  like  those  of  the  goat,  eight  incisors  below 
and  none  on  the  upper  row,  and  six  grinding  teeth  at  the  back  of  each  side 


282 


Handbook  of  Nature-Study 


of  each  jaw.  This  arrangement  of  teeth  on  the  small,  delicate,  pointed 
jaws  enables  the  sheep  to  crop  herbage  where  cattle  would  starve;  it  can 
cut  the  small  grass  off  at  its  roots,  and  for  this  reason,  where  vast  herds  of 
sheep  range,  they  leave  a desert  behind  them.  This  fact  brought  about  a 
bitter  feud  between  the  cattle  and  sheep  men  in  the  far  West.  In  forests, 
flocks  of  sheep  completely  kill  all  underbrush,  and  now  they  are  not  per- 
mitted to  run  in  government  reserves. 

The  sheep’s  legs  are  short  and  delicate  below  the  ankle.  The  upper 
portion  is  greatly  developed  to  help  the  animal  in  leaping,  a peculiarity  to 
which  we  owe  the  “leg  of  lamb”  as  a table  delicacy.  The  hoof  is  cloven, 
that  is,  the  sheep  walks  upon  two  toes;  it  has  two  smaller  toes  above  and 
behind  these.  There  is  a little  gland  between  the  front  toes  which  secretes

an  oily  substance,  which  perhaps  serves  in  preventing  the  hoof  from 
becoming  too  dry.  The  ears  are  large  and  are  moved  to  catch  better  the 
direction  of  sound.  The  eyes  are  peculiar;  in  the  sunlight  the  pupil  is  a 
mere  slit,  while  the  iris  is  yellow  or  brownish,  but  in  the  dark,  even  of  the 
stable,  the  pupils  enlarge,  almost  covering  the  eye.  The  ewes  either  lack 
horns  or  have  small  ones,  but  the  horns  of  wild  rams  are  large,  placed  at  the 
side  of  the  head  and  curled  outward  in  a spiral.  These  horns  are  perhaps 
not  so  much  for  fighting  the  enemy  as  for  rival  rams.  The  ram  can  strike 
a hard  blow  with  head  and  horns,  coming  at  the  foe  head  on,  while  the 
goat  always  strikes  sidewise.  So  fierce  is  the  blow  of  the  angry  sheep,  that 
an  ancient  instrument  of  war  was  fashioned  like  a ram’s  head  and  used  to 
knock  down  walls,  and  was  called  a battering  ram.  A sheep  shows  anger 
by  stamping  the  ground  with  the  front  feet.  The  habit  of  rumination 
enables  the  sheep  to  feed  in  a flock  and  then  retire  to  some  place  to  rest 
and  chew  the  cud,  a performance  peculiarly  funny  in  the  sheep. 


Mammal  Study

Sheep  under  attack  and  danger  are  silent;  ordinarily  they  keep  up  a 
constant,  gentle  bleating  to  keep  each  other  informed  of  their  where- 
abouts; they  also  give  a peculiar  call  when  water  is  discovered,  and 
another  to  inform  the  flock  that  there  is  a stranger  in  the  midst;  they  also 
give  a peculiar  bleat,  when  a snake  or  other  enemy  which  they  conquer,  is 
observed.  Their  sense  of  smell  is  very  acute.  Mary  Austin  says, 
“Young  lambs  are  principally  legs,  the  connecting  body  being  simply  a 
contrivance  for  converting  milk  into  more  leg,  so  you  understand  how  it  is 
that  they  will  follow  the  flock  in  two  days  and  are  able  to  take  the  trail  in 
a fortnight,  traveling  four  and  five  miles  a day,  falling  asleep  on  their  feet 
and  tottering  forward  in  the  way.” 

The  older  lambs  have  games  which 
they  play  untiringly,  and  which  fit 
them  to  become  active  members  of  the 
flock;  one,  is  the  regular  game  of 
“Follow  My  Leader,”  each  lamb 
striving  to  push  ahead  and  attain 
the  place  of  leader.  In  playing  this 
the  head  lamb  leads  the  chase  over 
most  difficult  places,  such  as  logs, 
stones  and  across  brooks;  thus  is  a 
training  begun  which  later  in  life  may 
save  the  flock.  The  other  game  is 
peculiar  to  stony  pastures;  a lamb 
climbs  to  the  top  of  a boulder  and  its 
comrades  gather  around  and  try  to 
butt  it  off;  the  one  which  succeeds  in 
doing  this,  climbs  the  rock  and  is  “it.”  This  game  leads  to  agility  and 
sure-footedness.  A lamb’s  tail  is  long  and  is  most  expressive  of  lambkin 
bliss,  when  feeding  time  comes;  but,  alas!  it  has  to  be  cut  off  so  that  later 
it  will  not  become  matted  with  burrs  and  filth.  In  southern  Russia  there 
is  a breed  of  sheep  with  large,  flat,  fat  tails  which  are  esteemed,  as 
a great  table  delicacy.  This  tail  becomes  so  cumbersome  that  wheels 
are  placed  beneath  it,  so  that  it  trundles  along  behind  its  owner. 

We  have  a noble  species  of  wild  sheep  in  the  Rocky  Mountains 
which  is  likely  to  become  extinct  soon.  The  different  breeds  of 
domesticated  sheep  are  supposed  to  have  been  derived  from  different 
wild  species.  Of  the  domesticated  varieties,  we  have  the  Merinos 
which  originated  in  Spain  and  which  give  beautiful,  long,  fine  wool 
for  our  fabrics;  but  their  flesh  is  not  very  attractive.  The  Merinos 
have  wool  on  their  faces  and  legs  and  have  wrinkled  skins.  The  English 
breeds  of  sheep  have  been  especially  developed  for  mutton,  although 
their  wool  is  valuable.  Some  of  these  like  the  Southdown,  Shropshire, 
and  Dorset,  give  a medium  length  of  wool,  while  the  Cotswold  has 
very  long  wool,  the  ewes  having  long  strings  of  wool  over  their  eyes 
in  the  fashion  of  “bangs.” 

The  dog,  as  descended  from  the  wolf,  is  the  ancient  enemy  of  sheep ; 
and  even  now  after  hundreds  of  years  of  domestication,  some  of  our 
dogs  will  revert  to  savagery  and  chase  and  kill  sheep.  This,  in  fact, 
has  been  one  of  the  great  drawbacks  to  sheep  raising  in  the  '’^Eastern 
United  States.  The  collie,  or  sheep-dog,  has  been  bred  so  many  years  as 
the  special  care-taker  of  sheep,  that  a beautiful  relationship  has  been

established  between  these  dogs  and  their  flocks.  For  instances  of  this, 
read  the  chapter  on  sheep-dogs  in  A Country  Reader;  “Wully”  in  Wild 
Animals  I Have  Known,  and  “Bob,  Son  of  Battle.” 

LESSON  LXVI 
The  Sheep 

Leading  thought — Sheep  live  naturally  in  high  altitudes.  When 
attacked  by  enemies,  they  follow  their  leader  over  difficult  and  dangerous 
mountain  places. 

Method — The  questions  of  this  lesson  should  be  given  to  the  pupils  and 
the  observations  should  be  made  upon  the  sheep  in  pasture  or  stable. 
Much  written  work  may  be  done  in  connection  with  this  lesson.  The 
following  topics  are  suggested  for  themes : “The  Methods  by  which  Wool 

is  Made  into  Cloth,”  “The  Rocky  Mountain  Sheep,”  “The  Sheep-herders 
of  California  and  their  Flocks,”  “The  True  Story  of  a Cosset  Lamb.” 


Observations — 1.  What  is  the  chief  character  that  separates  sheep 
from  other  animals?  What  is  the  difference  between  wool  and  hair? 
Why  is  wool  of  special  use  to  sheep  in  their  native  haunts  ? Is  there  any 
hair  on  sheep? 

2.  Where  do  the  wild  sheep  live?  What  is  the  climate  in  these 
places?  Does  wool  serve  them  well  on  this  account?  What  sort  of 
pasturage  do  sheep  find  on  mountains?  Could  cows  live  where  sheep 
thrive?  Describe  the  sheep’s  teeth  and  how  they  are  arranged  to  enable 
it  to  crop  vegetation  closely?  What  happens  to  the  vegetation  on  the 
range,  when  a great  flock  of  sheep  passes  over  it  ? Why  are  sheep  not 
allowed  in  our  forest  preserves? 


Mammal  Study 


285 


3.  What  are  the  chief  enemies  of  sheep  in  the  wilderness?  How  do 
the  sheep  escape  them?  Describe  the  foot  and  leg  of  the  sheep  and 
explain  how  they  help  the  animal  to  escape  its  enemies.  We  say  of  cer- 
tain men  that  they  “follow  like  a flock  of  sheep.”  Why  do  we  make  this 
comparison  ? What  has  this  habit  of  following  the  leader  to  do  with  the 
escape  of  sheep  from  wolves  and  bears? 

4.  How  do  sheep  fight?  Do  both  rams  and  ewes  have  horns?  Do 
they  both  fight  ? How  does  the  sheep  show  anger  ? Give  your  experience 
with  a cross  cosset  lamb. 

5.  Do  you  think  that  sheep  can  see  and  hear  well?  What  is  the  posi- 
tion of  the  sheep’s  ears  when  it  is  peaceful?  When  there  is  danger? 
How  do  the  sheep’s  eyes  differ  from  those  of  the  cow? 

6.  Does  the  sheep  chew  its  cud  like  the  cow?  Describe  the  actionas 
performed  by  the  sheep.  How  is  this  habit  of  cud  chewing  of  use  to  the 
wild  sheep  ? 

7.  Describe  a young  lamb.  Why  has  it  such  long  legs?  How  do  es 
it  use  its  tail  to  express  joy?  What  happens  to  this  tail  later?  What 
games  have  you  seen  lambs  play?  Tell  all  the  stories  of  lambs  that  you 
know. 

8.  How  much  of  sheep  language  do  you  understand?  What  is  the 
use  to  the  wild  flock  of  the  constant  bleating? 

9.  For  what  purposes  do  we  keep  sheep?  How  many  breeds  of 
sheep  do  you  know?  What  are  the  chief  differences  between  the  English 
breeds  and  the  Merinos?  Where  and  for  what  purposes  is  the  milk  of 
sheep  used? 

10.  Have  you  ever  seen  a collie  looking  after  a herd  of  sheep?  If  so, 
describe  his  actions.  Did  you  ever  know  of  dogs  killing  sheep  ? At  what 
time  of  day  or  night  was  this  done?  Did  you  ever  know  of  one  dog 
attacking  a flock  of  sheep  alone.  What  is  there  in  the  dog’s  ancestry 
which  makes  two  or  three  dogs,  when  hunting,  give  chase  and  attack 
sheep  ?

THE  HORSE 

Teacher's  Story 

“ There  was  once  a little  animal  no  bigger  than  a fox) 

And  on  five  toes  he  scrambled  over  Tertiary  rocks. 

They  called  him  Eohippus,  and  they  called  him  very  small , 

And  they  thought  him  of  no  value  when  they  thought  of  him  at  all. 

Said  the  little  Eohippus,  I am  going  to  be  a horse! 

And  on  my  middle  finger  nails  to  run  my  earthly  course! 

I am  going  to  have  a flowing  tail!  I am  going  to  have  a mane! 

And  I am  going  to  stand  fourteen  hands  high  on  the  Psychozooic  plain!" 

— Mrs.  Stetson. 

It  was  some  millions  of  years  ago,  that  Eohippus  lived  out  in  the 
Rocky  Mountain  Range;  its  fore  feet  had  four  toes  and  the  splint  of  the 
fifth ; the  hind  feet  had  three  toes  and  the  splint  of  the  fourth.  Eohippus 
was  followed  down  the  geologic  ages  by  the  Orohippus  and  the  Mesohippus 
and  various  other  hippuses,  which  showed  in  each  age  a successive  enlarge- 
ment and  specialization  of  the  middle  toe  and  the  minimizing  and  final 
loss  of  the  others.  This  first  little  horse  with  many  toes,  lived  when  the 
earth  was  a damp,  warm  place  and  when  animals  needed  toes  to  spread 
out  to  prevent  them  from  miring  in  the  mud.  But  as  the  ages  went  on, 
the  earth  grew  colder  and  drier,  and  a long  leg  ending  in  a single  hoof,  was 
very  serviceable  in  running  swiftly  over  the  dry  plains;  and  according  to 
the  story  read  in  the  fossils  of  the  rocks,  our  little  American  horses 
migrated  to  South  America;  and  also  trotted  dry-shod  over  to  Asia  in 
the  Mid-pleocine  age,  arriving  there  sufficiently  early  to  become  the  com- 
panion of  prehistoric  man.  In  the  meantime,  horses  were  first  hunted  by

savage  man  for  theii 
flesh,  but  were  later 
ridden.  At  present, 
there  are  wild  horses 
in  herds  on  the  plains 
of  Tartary;  and  there 
are  still  sporadic  herds 
of  mustangs  on  the 
great  plains  of  our 
own  country,  although 
for  the  most  part,  they 
are  branded  and  be- 
long to  someone,  even 
though  they  live  like 
wild  horses ; these 
American  wild  horses 
are  supposed  to  be 
descendents  of  those 
brought  over  (centu- 
ries ago  by  the  Span- 
iards. The  Shetland  Four-toed,  horse  of  the  Eocene  period. 

ponies  are  also  wild  After  Charles  R-  Knight- 

in  the  islands  north  of  Scotland,  and  the  zebras  roam  the  plains  of  Africa 
the  most  truly  wild  of  all.  In  a state  of  wildness,  there  is  always  a stal- 
lion at  the  head  of  a herd  of  mares,  and  he  has  to  win  his  position  and  keep 
it  by  superior  strength  and  prowess.  Fights  between  stallions  are  terrible 
to  witness,  and  often  result  in  the  death  of  one  of  the  participants.  The 
horse  is  well  armed  for  battle ; .his  powerful  teeth  can  inflict  deep  wounds 
and  he  can  kick  and  strike  hard  with  the  front  feet;  still  more  efficient 
is  the  kick  made  with  both  hind  feet  while  the  weight  of  the  body  is  borne 
on  the  front  feet,  and  the  head  of  the  horse  is  turned  so  as  to  aim  well  the 
terrible  blow.  There  are  no  wild  beasts  of  prey  which  will  not  slink  away 
to  avoid  a herd  of  horses.  After  attaining  their  growth  in  the  herd  with 
their  mothers,  the  young  males  are  forced  by  the  leader  to  leave  and  go  off 
by  themselves;  in  turn,  they  must  by  their  own  strength  and  attractions, 
win  their  following  of  mares.  However,  there  are  times  and  places  where 
many  of  these  herds  join,  making  large  bands  wandering  together. 

The  length  of  the  horse’s  leg  was  evidently  evolved  to  meet  the  need 
for  flight  before  fierce  and  swift  enemies,  on  the  great  ancient  plains. 
The  one  toe,  with  its  strong,  sharp  hoof,  makes  a fit  foot  for  such  a long 
leg,  since  it  strikes  the  ground  with  little  waste  of  energy  and  is  sharp 
enough  not  to  slip , but  it  is  not  a good  foot  for  marshy  places ; a horse  will 
mire  where  a cow  can  pass  in  safety.  The  development  of  the  middle  toe 
into  a hoof  results  in  lifting  the  heel  and  wrist  far  up  the  leg,  making  them 
appear  to  be  the  knee  and  elbow,  when  compared  with  the  human  body. 

The  length  of  neck  and  head  are  necessary  in  order  that  an  animal, 
with  such  length  of  leg  as  the  horse,  may  be  able  to  graze.  The  head  of 
the  horse  tells  much  of  its  disposition ; a perfect  head  should  be  not  too 
large,  broad  between  the  eyes  and  high  between  the  ears,  while  below  the 
eyes,  it  should  be  narrow.  The  ears,  if  lopped  or  turned  back,  denote  a 
treacherous  disposition.  They  should  point  upward  or  forward ; the  ears 
laid  back  is  always  a sign  that  the  horse  is  angry;  sensitive,  quick-moving 


288 


Handbook  of  N ature-Study 


ears  indicate  a high-strung,  sensitive  animal.  The  eyes  are  placed  so 
that  the  horse  can  see  in  front,  at  the  side  and  behind,  the  last  being 

necessary  in  order  to  aim  a kick.  Hazel 
eyes  are  usually  preferred  to  dark  ones, 
and  they  should  be  bright  and  prominent. 
The  nostrils  should  be  thin-skinned,  wide- 
flaring  and  sensitive;  as  a wild  animal, 
scent  was  one  of  the  horse’s  chief  aids  in 
detecting  the  enemy.  The  lips  should 
not  be  too  thick  and  the  lower  jaw  should 
be  narrow  where  it  joins  the  head. 

The  horse’s  teeth  are  peculiar;  there 
are  six  incisors  on  both  jaws;  behind  them 
is  a bare  space  called  the  bar,  of 
which  we  have  made  use  for 
placing  4he  bit.  Back  of  the 
bar,  there  are  six  molars  or 
grinders  on  each  side  of  each  jaw.  At  the  age  of  about  three 
years,  canine  teeth  or  tushes  appear  behind  the  incisors;  these  are 
more  noticeable  in  males,  and  never  seem  to  be  of  much  use. 
Thus,  the  horse  has  on  each  jaw,  when  full-grown,  six  incisors,  two 
canines,  and  twelve  molars,  making  forty  teeth  in  all.  The  incisors  are 
prominent  and  enable  the  horse  to  bite  the  grass  more  closely  than  can 
the  cow.  The  horse  when  chewing,  does  not  have  the  sidewise  motion  of 
the  jaws  peculiar  to  the  cow  and  sheep. 

The  horse’s  coat  is,  when  rightly  cared  for,  glossy  and  beautiful;  but 
if  the  horse  is  allowed  to  run  out  in  the  pasture  all  winter,  the  coat  becomes 
very  shaggy,  thus  reverting  to  the  condition  of  wild  horses  which  stand  in 
need  of  a warmer  coat  for  winter;  the  hair  is  shed  every  year.  The 
mane  and  the  forelock  are  useful  in  protecting  the  head  and  neck  from 
flies;  the  tail  is  also  an  efficient  fly-brush.  Although  the  mane  and  tail

have  thus  a practical  value,  they  add  greatly  to  the  animal’s  beauty.  To 
dock  a horse’s  tail  as  an  ornament  is  as  absurd  as  the  sliced  ears  and  welted 
cheeks  of  savages;  and  horses  thus  mutilated  suffer  greatly  from  the 
attacks  of  flies. 

Owing  to  the  fact  that  wild  horses  made  swift  flight  from  enemies,  the 
colts  could  not  be  left  behind  at  the  mercy  of  wolves.  Thus  it  is,  the  colt 
like  the  lamb,  is  equipped  with  long  legs  from  the  first,  and  can  run  very 
rapidly;  as  a runner,  it  could  not  be  loaded  with  a big  compound  stomach 
full  of  food,  like  the  calf,  and  therefore,  must  needs  take  its  nourishment 
from  the  mother  often.  The  colt’s  legs  are  so  long  that,  in  order  to  graze, 
it  spreads  the  front  legs  wide  apart  in  order  that  it  may  reach  the  grass 
with  its  mouth.  When  the  colt  or  the  horse  lies  down  out  of  doors  and  in 
perfect  freedom,  it  lies  flat  upon  the  side.  In  lying  down,  the  hind  quar- 
ters go  first,  and  in  rising,  the  front  legs  are  thrust  out  first. 


English  draft-horse. 


The  horse  has  several  natural  gaits  and  some  that  are  artificial.  Its 
natural  methods  of  progression  are  the  walk,  the  trot,  the  amble,  the 
gallop.  When  walking  there  are  always  two  or  more  feet  on  the  ground 
and  the  movement  of  the  feet  consists  in  placing  successively  the  right 
hind  foot,  the  right  fore  foot,  left  hind  foot,  left  fore  foot,  right  hind  foot, 
etc.  In  trotting,  each  diagonal  pair  of  legs  is  alternately  lifted  and  thrust 
forward,  the  horse  being  unsupported  twice  during  each  stride.  In 
ambling,  the  feet  are  moved  as  in  the  walk,  only  differing  in  that  a hind 
foot  or  a fore  foot  is  lifted  from  the  ground,  before  its  fellow  fore  foot  or 
hind  foot  is  set  down.  In  a canter,  the  feet  are  landed  on  the  ground  in 
the  same  sequence  as  a walk  but  much  more  rapidly;  and  in  the  gallop, 
the  spring  is  made  from  the  fore  foot  and  the  landing  is  on  the  diagonal 
hind  foot  and  just  before  landing,  the  body  is  in  the  air  and  the  legs  are  all 
bent  beneath  it.

An  excellent  horseman  once  said  to  me,  “The  whip  may  teach  a horse 
to  obey  the  voice,  but  the  voice  and  hand  control  the  well-broken  horse,” 
and  this  epitomizes  the  best  horse  training.  He  also  said,  “The  horse 
knows  a great  deal,  but  he  is  too  nervous  to  make  use  of  his  knowledge 
when  he  needs  it  most.  It  is  the  horse’s  feelings  that  I rely  on.  He 
always  has  the  use  of  his  feelings  and  the  quick  use  of  them.”  It  is  a 
well-known  fact  that  those  men  who  whip  and  scold  and  swear  at  their 
horses,  are  meantime  showing  to  the  world  that  they  are  fools  in  this 
particular  business.  Many  of  the  qualities  which  we  do  not  like  in  our 
domesticated  horses,  were  most  excellent  and  useful  when  the  horses  were 
wild,  for  instance,  the  habit  of  shying  was  the  wild  horse’s  method  of 
escaping  the  crouching  foe  in  the  grass.  This  habit  as  well  as  many  others 


Saddle-horse. 

is  best  controlled  by  the  voice  of  the  driver  instead  of  a blow  from  the 
whip. 

Timothy  hay,  or  hay  mixed  with  clover,  form  good,  bulky  food  for  the 
horse,  and  oats  and  com  are  the  best  concentrated  food.  Oats  are  best  for 
driving-horses  and  com  for  the  working  team.  Dusty  hay  should  not  be 
fed  to  a horse;  but  if  unavoidable,  it  should  always  be  dampened  before 
feeding.  A horse  should  be  fed  with  regularity,  and  should  not  be  used 
for  a short  time  after  having  eaten.  If  the  horse  is  not  warm,  it  should 
be  watered  before  feeding,  and  in  the  winter  the  water  should  have  the 
chill  taken  off.  The  frozen  bit  should  be  warmed  before  being  placed  in 
the  horse’s  mouth;  if  anyone  doubts  the  wisdom  of  this,  let  him  put  a 
frozen  piece  of  steel  in  his  own  mouth.  The  tight-drawn,  cruel  use  of  the 
over  check-rein  should  not  be  permitted,  although  a moderate  check  is 
often  needed  and  is  not  cruel.  When  the  horse  is  sweating,  it  should  be 
blanketed  immediately  if  hitched  outside  in  cold  weather;  but  in  the 
barn,  the  blanket  should  not  be  put  on  until  the  perspiration  has  stopped 
steaming.  The  grooming  of  a horse  is  a part  of  its  rights,  and  its  legs 
should  receive  more  attention  during  this  process  than  its  body,  a fact 
not  always  well  understood. 

The  breeds  of  horses  may  always  be  classified  more  or  less  distinctly  as 
follows:  Racers  or  thoroughbreds;  the  saddle-horse,  or  hunter;  the

LESSON  LXVII 
The  Horse 

Leading  thought — The  horse  as  a wild  animal  depended  largely  upon 
its  strength  and  fleetness  to  escape  its  enemies,  and  these  two  qualities 
have  made  it  of  greatest  use  to  man. 

Method — Begin  this  study  of  the  horse  with  the  stories  of  wild  horses. 
“The  Pacing  Mustang”  in  Wild  Animals  I Have  Known,  is  an  excellent 
story  to  show  the  habits  of  the  herds  of  wild  horses ; Chapter  first  in  A 
Country  Reader  and  the  story  of  horses  in  Life  of  Animals  are  excellent  as 
a basis  for  study.  Before  beginning  actual  study  of  the  domestic  horses, 
ask  for  oral  or  written  English  exercises  descriptive  of  the  lives  of  the 
wild  horses.  Get  Remington’s  pictures  illustrating  the  wild  horses  of 
America.  After  the  interest  has  been  thus  aroused  the  following  observa- 
tions may  be  suggested,  a few  at  a time,  to  be  made  incidentally  in  the 
street  or  in  the  stable. 

Observations — i . Compare  the  length  of  the  legs  of  the  horse  with  its 
height.  Has  any  other  domestic  animal  legs  as  long  in  proportion? 
What  habits  of  the  ancestral  wild  horses  led  to  the  development  of  such 
long  legs?  Do  you  think  the  length  of  the  horse’s  neck  and  head  corre- 
spond to  the  length  of  its  legs?  Why? 


coach-horse;  the  draft-horse  and  the  pony.  For  a description  of  breeds 
see  dictionaries  or  cyclopedias.  Of  the  draft-horses,  the  Percherons, 
Shires  and  Clydesdales  are  most  common;  of  the  carriage  and  coach- 
horses,  the  English  hackney  and  the  French  and  German  coach-horses  are 
famed  examples.  Of  the  roadster  breeds,  the  American  trotter,  the 
American  saddle-horse  and  the  English  thoroughbred  are  most  famous.

2.  Study  the  horse’s  leg  and  foot.  The  horse  walks  on  one  tee. 
Which  toe  do  you  think  it  is  ? What  do  we  call  the  toe-nail  of  the  horse  ? 
What  advantage  is  this  sort  of  a foot  to  the  horse  ? Is  it  best  fitted  for 
running  on  dry  plains  or  for  marshy  land?  Does  the  hoof  grow  as  our 
nails  do?  Do  you  know  whether  there  were  ever  any  horses  with  three 
toes  or  four  toes  on  each  foot?  Make  a sketch  of  the  horse’s  front  and 
hind  leg  and  label  those  places  which  correspond  to  our  wrist,  elbow, 
shoulder,  hand,  heel,  knee  and  hip. 

3.  Where  are  the  horse’s  ears  placed  on  the  head?  How  do  they 

move?  Do  they  flap  back  and  forth  like  the  cow’s  ears  when  they  are 
moved,  or  do  they  turn  as  if  on  a pivot?  What  do  the  following  different 
positions  of  the  horse’s  ears  indicate : When  lifted  and  pointing  forward  ? 

When  thrown  back?  Can  you  tell  by  the  action  of  the  ears  whether  a 
horse  is  nervous  and  high-strung  or  not  ? 

4.  What  is  the  color  of  the  horse’s  eyes?  The  shape  of  the  pupil? 
What  advantage  does  the  position  of  the  eyes  on  the  head  give  to  the  wild 
horse ? Why  do  we  put  blinders  on  a horse  ? Can  you  tell  by  the  expres- 
sion of  the  eye  the  temper  of  the  horse? 

5.  Look  at  the  mouth  and  nose.  Are  the  nostrils  large  and  flaring?

8.  Why  do  colts  need  to  be  so  long-legged?  How  does  a colt  have 
to  place  its  front  legs  in  order  to  reach  down  and  eat  the  grass?  Does  the 
colt  need  to  take  its  food  from  the  mother  often?  How  does  it  differ

Many  horses  shy  a good  deal  at  objects  they  meet  on  the  road.  This  mostly  arises 
from  nervousness,  because  the  objects  are  not  familiar  to  them.  Therefore,  to  cure  the 
habit,  you  must  get  your  horse  accustomed  to  what  he  sees,  and  so  give  him  confidence. 

Be  careful  never  to  stop  a horse  that  is  drawing  a vehicle  or  load  in  the  middle 
of  a hill,  except  for  a rest;  and  if  for  a rest,  draw  him  across  the  hill  and  place  a big 
stone  behind  the  wheel,  so  that  the  strain  on  the  shoulder  may  be  eased.  Unless  abso- 
lutely necessary  never  stop  a horse  on  a hill  or  in  a rut,  so  that  when  he  starts  again  it 
means  a heavy  tug.  Many  a horse  has  been  made  a jibber  and  his  temper  spoilt  by 
not  observing  this  rule.

CATTLE 

Teacher’s  Story 

That  in  numbers  there  is  safety,  is  a basic  principle  in  the  lives  of 
wild  cattle,  probably  because  their  chief  enemies,  the  wolves,  hunted  in 
packs.  It  has  often  been  related  that,  when  the  herd  is  attacked  by 
wolves,  the  calves  are  placed  at  the  center  of  the  circle  made  by  the  cattle, 
standing  with  heads  out  and  horns  ready  for  attack  from  every  quarter. 
But  when  a single  animal,  like  a bear  or  tiger,  attacks  any  of  the  herd, 
they  all  gather  around  it  in  a narrowing  circle  of  clashing  horns,  and 
many  of  these  great  beasts  of  prey  have  thus  met  their  death.  The  cow 
is  as  formidable  as  the  bull  to  the  enemy,  since  her  horns  are  strong  and 
sharp  and  she  tosses  her  victim,  unless  it  is  too  large.  The  heavy  head, 
neck  and  short  massive  horns  of  the  bull,  are  not  so  much  for  defence 
against  enemies  as  against  rival  bulls.  The  bull  not  only  tosses  and  gores 
his  victim,  but  kneels  or  tramples  upon  it.  Both  have  effective  weapons 
of  defence  in  the  hind  feet,  which  kick  powerfully.  The  buffalo  bull  of 
India  will  attack  a tiger  single  handed,  and  usually  successfully.  It  is  a 
strange  thing  that  all  cattle  are  driven  mad  by  the  smell  of  blood,  and 
weird  stories  are  told  of  the  stampeding  of  herds  from  this  cause,  on  the 
plains  of  our  great  West. 

Cattle  are  essentially  grass  and  herbage  eaters,  and  their  teeth  are 
peculiarly  arranged  for  this.  There  are  eight  front  teeth  on  the  lower 
jaw,  and  a homy  pad  opposite  them  on  the  upper  jaw.  Back  of  these  on 
each  jaw  there  is  a bare  place  and  six  grinding  teeth  on  each  side.  As  a 
cow  crops  the  herbage,  her  head  is  moved  up  and  down  to  aid  in  severing 
the  leaves,  and  the  peculiar  sound  of  the  tearing  of  the  leaves  thus  made 
is  not  soon  forgotten  by  those  who  have  heard  it.  In  the  wild  or  domes- 
ticated state  the  habit  of  cud-chewing  is  this : The  cattle  graze  in  morn- 

ings and  evenings,  swallowing  the  food  as  fast  as  cropped,  and  storing  it

mother;  the  young 
for  a long  journey; 
“frozen”  and  will 
never  stir  unless 
actually  touched. 
As  the  mother  is 
obliged  to  be  absent 
for  some  time  grazing 
with  the  herd,  the 
calf  is  obliged  to  go 
without  nourishment 
for  a number  of  hours, 
and  so  it  is  provided 
with  a large  compound 
stomach  which,  if  filled 
twice  per  day,  suffices 
to  insure  health  and 
growth.  The  cow,  on 
the  other  hand,  giv- 
ing her  milk  out  only 
twice  per  day,  needs  a 
large  udder  in  which 
to  store  it.  The  size 
of  the  udder  is  what 
has  made  the  cow 
useful  to  us  as  a milch 
animal. 

A fine  cow  is  a 
beautiful  creature,  her 
soft  yellow  skin  be- 
neath the  sleek  coat 
of  short  hair,  the  well 
proportioned  body, 
the  mild  face,  crowned 
with  spreading, 
polished  horns  and 
illuminated  with  large 
gentle  eyes,  are  all 


in  their  ruminating  stomachs.  During  the 
heat  of  the  day,  they  move  to  the  shade, 
preferably  to  the  shady  banks  of  streams, 
and  there  in  quiet  the  food  is  brought 
up,  a small  portion  at  a time,  and  chewed  with 
a peculiar  sidewise  movement  of  the  jaws  and 
then  swallowed,  passing  to  the  true  stomach. 
There  is  probably  no  more  perfect  picture  of 
utter  contentment,  than  a herd  of  cows  chewing 
their  cuds  in  the  shade,  or  standing  knee-deep 
in  the  cool  stream  on  a summer’s  day.  The 
cattle  in  a herd  when  grazing,  keep  abreast  and 
move  along,  heads  in  the  same  direction. 

Connected  with  the  grazing  habit,  is  that  of 
the  hiding  of  the  new-born  calf  by  its 
calf  is  a wabbly  creature  and  ill-fitted 
so  the  mother  hides  it,  and  there  it  stays

elements  of  beauty  which  artists  have  recognized,  especially  those 
of  the  Dutch  school.  The  ancients  also  admired  bovine  eyes,  and 
called  their  most  beautiful  goddess  the  ox-eyed  Juno. 

The  cow’s  ears  can  be  turned  in  any  direction,  and  her  sense  of  hearing 
is  keen;  so  is  her  sense  of  smell,  aided  by  the  moist,  sensitive  skin  of  the 
nose;  she  always  sniffs  danger  and  also  thus  tests  her  food.  Although  a 
cow  if  well  kept  has  a sleek  coat,  when  she  is  allowed  to  run  out  of  doors 
during  the  winter,  her  hair  grows  long  and  shaggy  as  a protection.  The 
cow  walks  on  two  toes,  or  as  we  say  has  a split  hoof.  She  has  two  lesser 
toes  above  and  behind  the  hoofs  which  we  call  dew-claws.  The  part  of 
her  leg  which  seems  at  first  glance  to  be  her  knee,  is  really  her  wrist  or 
ankle.  Although  short-legged,  the  cow  is  a good  runner,  as  those  who 
have  chased  her  can  bear  witness.  She  can  walk,  gallop  and  has  a pacing 
trot;  she  is  a remarkable  jumper,  often  taking  a fence  like  a deer;  she 
also  has  marvelous  powers  as  a swimmer,  a case  being  on  record  where  a 
cow  swam  five  miles.  But  a cow  would  be  illy  equipped  for  comfort  if  it 
were  not  for  her  peculiar  tail,  which  is  made  after  the  most  approved 
pattern  of  fly-brushes,  and  is  thus  used.  Woe  betide  the  fly  she  hits  with 
it,  if  the  blow  is  as  efficient  as  that  which  she  incidentally  bestows  on  the 
head  of  the  milker.  It  is  to  get  rid  of  flies,  that  the  cattle,  and  especially 
the  buffaloes,  wallow  in  the  mud,  and  thus  coat  themselves  with  a fly- 
proof  armor. 

There  is  a fairly  extensive  range  of  emotions  expressed  in  cattle 
language,  from  the  sullen  bellow  of  the  angry  animal  to  the  lowing  which 
is  the  call  of  the  herd,  and  the  mooing  which  is  meant  for  the  calf;  and 
there  are  many  other  bellowings  and  mutterings  which  we  can  partially 
understand. 

Every  herd  of  cows  has  its  leader,  which  has  won  the  position  by  fair 
fight.  Add  a new  cow  to  the  herd,  and  there  is  at  once  a trial  of  strength, 
to  adjust  her  to  her  proper  place;  and  in  a herd  of  cows,  the  leader  leads; 
she  goes  first  and  no  one  may  say  her  nay.  In  fact,  each  member  of  the 
herd  has  her  place  in  it ; and  that  is  why  it  is  so  easy  to  teach  cows  each 
to  take  her  own  stanchion  in  the  stable.  In  a herd  of  forty  cows  which  I 
knew,  each  cow  took  her  stanchion,  no  matter  in  what  order  she  happened 
to  enter  the  stable. 

A cow  at  play  is  a funny  sight ; her  tail  is  lifted  aloft  like  a pennant  and 
she  kicks  as  lightly  as  if  she  were  made  of  rubber.  She  is  also  a sure- 
footed beast,  as  anyone  can  attest  who  has  seen  her  running  down  the 
rocky  mountain  sides  of  the  Alps,  at  a headlong  pace  and  never  making  a 
mistake.  In  lying  down,  the  cow  first  kneels  with  the  front  legs,  or 
rather  drops  on  her  wrists,  and  then  the  hind  quarters  go  down,  and  then 
the  front  follow.  She  does  not  lie  flat  on  her  side  when  resting,  like  the 
horse  when  at  ease,  but  with  her  legs  partially  under  her.  In  getting  up, 
she  rests  upon  her  wrists  and  then  lifts  the  hind  quarters. 

The  Usefulness  of  Cattle 

When  man  emerged  from  the  savage  state,  his  first  step  toward  civili- 
zation was  domesticating  wild  animals  and  training  them  for  his  own  use= 
During  the  nomad  stage,  when  tribes  wandered  over  the  face  of  the 
earth,  they  took  their  cattle  along.  From  the  first,  these  animals  have 
been  used  in  three  capacities : First,  for  carrying  burdens  and  as  draught 


298

animals;  second,  as  meat;  third,  as  givers  of  milk.  They  were  also  used 
in  the  earlier  ages  as  sacrifices  to  the  various  deities,  and  in  Egypt,  some 
were  held  as  sacred. 

As  beasts  of  burden  and  draft  animals,  oxen  are  still  used  in  many 
parts  of  the  United  States.  For  logging,  especially  in  pioneer  days,  oxen 
were  far  more  valuable  than  horses.  They  are  patient  and  will  pull  a few 
inches  at  a time,  if  necessary,  a tedious  work  which  the  nervous  horse 
refuses  to  endure.  Cows  too,  have  been  used  as  draft  animals,  and  are  so 
used  in  China  today,  where  they  do  most  of  the  plowing;  in  these  oriental 
countries  milk  is  not  consumed  to  any  extent,  so  the  cow  is  kept  for  the 
work  she  can  do.  In  ancient  times  in  the  East,  white  oxen  formed  a part 
of  royal  processions. 


Beef  cattle. 

Because  of  two  main  uses  of  cattle  by  civilized  man,  he  has  bred  them 
in  two  directions;  one  for  producing  beef,  and  one  for  milk.  The  beef 
cattle  are  chiefly  Aberdeen- Angus,  Galloway,  Short-horn  or  Durham,  and 
Hereford;  the  dairy  breeds  are  the  Jersey,  Guernsey,  Ayrshire,  Holstein- 
Frisian  and  Brown  Swiss.  The  beef  animal  is,  in  cross-section,  approxi- 
mately like  a brick  set  sidewise.  It  should  be  big  and  full  across  the  loins 
and  back,  the  shoulders  and  hips  covered  heavily  with  flesh,  the  legs  stout, 
the  neck  thick  and  short,  and  the  face  short;  the  line  of  the  back  is 
straight,  and  the  stomach  line  parallel  with  it.  Very  different  is  the 
appearance  of  the  milch  cow.  Her  body  is  oval,  instead  of  being  approxi- 
mately square  in  cross-section.  The  outline  of  her  back  is  not  straight. 


Mammal  Study

but  sags  in  front  of  the  hips,  which  are  prominent  and  bony.  The 
shoulders  have  little  flesh  on  them;  and  if  looked  at  from  above,  her  body 
is  wedge-shaped,  widening  from  shoulders  backward.  The  stomach  line 
is  not  parallel  with  the  back  bone,  but  slants  downward  from  the  shoulder 
to  the  udder.  The  following  are  the  points  that  indicate  a good  milch 
cow:  Head  high  between  the  .eyes,  showing  large  air  passages  and 

indicating  strong  lungs.  Eyes  clear,  large  and  placid,  indicating  good 
disposition.  Mouth  large,  with  a muscular  lower  jaw,  showing  ability  to 
chew  efficiently  and  rapidly.  Neck,  thin  and  fine,  showing  veins  through 
the  skin.  Chest  deep  and  wide,  showing  plenty  of  room  for  heart  and 
lungs.  Abdomen,  large  but  well  supported,  and  increasing  in  size  toward 
the  rear.  Ribs,  well  spread,  not  meeting  the  spine  like  the  peak  of  a roof, 
but  the  spine  must  be  prominent,  revealing  to  the  touch  the  separate 
vertebrae.  Hips,  much  broader  than  the  shoulders.  Udder,  large,  the 
four  quarters  of  equal  size,  and  not  fat;  the  “milk  veins”  which  carry 
the  blood  from  the  udder  should  be  large  and  crooked,  passing  into  the 
abdomen  through  large  openings.  Skin,  soft,  pliable  and  covered  with 
fine,  oily  hair.  She  should  have  good  digestion  and  great  powers  of 
assimilation.  The  milch  cow  is  a milk-making  machine,  and  the  more 
fuel  (food)  she  can  use,  the  greater  her  production. 

The  physiological  habits  of  the  beef  and  milch  cattle  have  been 
changed  as  much  as  their  structure.  The  food  given  to  the  beef  cow  goes 
to  make  flesh;  while  that  given  to  the  milch  cow  goes  to  make  milk, 
however  abundant  her  food.  Of  course,  there  are  all  grades  between  the 
beef  and  the  milch  types,  for  many  farmers  use  dual  herds  for  both. 
However,  if  a farmer  is  producing  milk  it  pays  him  well  to  get  the  best 
possible  machine  to  make  it,  and  that  is  always  a cow  of  the  right  type. 

A Geography  Lesson 

All  the  best  breeds  of  cattle  have  been  evolved  in  the  British  Isles  and 
in  Europe  north  of  Italy  and  west  of  Russia.  All  our  domesticated  cattle 
were  developed  from  wild  cattle  of  Europe  and  Asia.  The  cattle  which 
roam  in  our  rapidly  narrowing  grazing  lands  of  the  far  West  are  European 
cattle.  America  had  no  wild  cattle  except  the  bison.  In  geography 
supplementary  readers,  read  about  Scotland,  England,  the  Channel 
Islands,  the  Netherlands,  France  and  Switzerland  and  the  different  kinds 
of  cattle  developed  in  these  countries;  for  example,  “A  Holland  Dairy,” 
in  Northern  Europe,  Ginn  & Co. 

How  to  Produce  Good  Milk 

There  are  three  main  ingredients  of  milk — fat,  curd  and  ash.  The 
fat  is  for  the  purpose  of  supplying  the  animal  with  fat  and  we  make  it  into 
butter;  the  curd  supplies  muscle,  or  the  lean  meat  of  the  animal,  and 
is  the  main  ingredient  of  cheese,  although  cheese  to  be  good  should  con- 
tain a full  amount  of  butter  fat;  the  ash  which  may  be  seen  as  residue 
when  milk  is  evaporated,  builds  up  the  bone  of  the  animal.  The  best 
butter  cows  are  those  which  give  a larger  per  cent,  of  fat  and  a small 
per  cent,  of  curd,  like  the  Jerseys;  the  best  cheese  cows  are  those 
which  give  a fair  per  cent,  of  fat  and  a larger  yield  of  curd,  like  the 
Ayrshire  and  Holstein. 


3©o 


Handbook  of  Nature-Study 


A cow  for  producing  cheese,  is  not  profitable,  unless  she  gives  seven 
thousand  pounds  of  milk  per  year;  a butter  cow,  a Jersey  for  instance, 
should  produce  five  thousand  pounds  of  milk  per  year  to  be  really 
profitable. 

The  stable  where  milch  cows  are  kept  should  be  thoroughly  cleaned 
before  each  milking,  and  should  be  swept  each  day;  the  cows’  udders 
should  be  brushed,  and  the  milkers  should  wear  clean  aprons  and  should 
wash  their  hands  before  milking.  Milk  should  never  be  strained  in  the 
bam,  but  in  some  place  where  the  air  is  fresh.  If  milk  is  perfectly  clean, 
it  will  keep  sweet  much  longer;  sterilized  milk  put  in  bottles  will  keep 
sweet  for  weeks  and  even  months.  Loud  talking  should  not  be  permitted 
in  the  stables  while  the  cows  are  being  milked,  and  each  cow  should  be 
milked  by  the  same  person  for  the  entire  season. 


The  perfect  milch  type. 

Milk  to  be  legally  sold  in  New  York  State  must  possess  three  per  cent, 
of  butter  fat.  For  upper  grades  or  first  year  work  in  the  high  school, 
there  could  not  be  a more  profitable  exercise  than  teaching  the  pupils  the 
use  of  the  Babcock  milk  tester. 

The  Care  of  the  Milch  Cow 

The  importance  cannot  be  over-estimated  of  teaching  the  pupils  in 
rural  districts,  the  proper  care  of  milch  cattle  for  the  production  of  milk. 
The  milch  cow  is  a perfect  machine,  and  should  be  regarded  as  such  in 
producing  milk.  First,  she  should  have  plenty  of  food  of  the  right  kind, 
that  is,  a well-balanced  ration.  Second,  she  should  have  a warm,  clean 
stable  and  be  supplied  with  plenty  of  good,  fresh  air.  A cold  stable 
makes  it  necessary  to  provide  much  more  food  for  the  cow;  a case  on 
record  shows  that  when  a bam  was  opened  up  in  cold  weather  for  neces- 
sary repairing,  the  amount  of  milk  from  the  cows  stabled  in  it,  decreased 
ten  per  cent,  in  twenty-four  hours.  There  should  be  a protected  place  for

drinking,  if  the  cattle  must  be  turned  out  of  the  bam  for  water  in  winter; 
it  is  far  better  to  have  the  water  piped  into  the  barn,  although  the  herd 
should  be  given  a few  hours  each  day  in  the  open  air.  A dog  should 
never  be  used  for  driving  cows.  To  be  profitable,  a cow  should  give  milk 
ten  months  of  the  year  at  least.  Calves  should  be  dehorned  when  they 
are  a few  days  old  by  putting  caustic  potash  on  the  budding  horns,  thus 
obviating  the  danger  of  damaging  the  cow  by  dehorning. 

In  a properly  run  dairy,  a pair  of  scales  stands  near  the  can  for  receiv- 
ing the  milk;  and  as  the  milk  from  each  cow  is  brought  in,  it  is  weighed 
and  the  amount  set  down  opposite  the  cow’s  name  on  a “milk  sheet,”  that 
is  tacked  on  the  wall,  near  by.  At  the  end  of  each  week,  the  figures  on 
the  milk  sheet  are  added,  and  the  farmer  knows  just  how  much  milk  each 
cow  is  giving  him,  and  whether  there  are  any  in  the  herd  which  are  not 
paying  their  board.

LESSON  LXVIII 
The  Cow 

Leading  thought — Certain  characteristics  which  enable  the  cow  to  live 
successfully  as  a wild  animal,  have  rendered  her  of  great  use  to  us  as  a 
domestic  animal. 

Method — Begin  the  lesson  with  leading  the  pupils  to  understand  the 
peculiar  adaptation  of  cattle  for  success,  as  wild  animals.  This  will  have 
to  be  done  largely  by  reading  and  asking  for  oral  or  written  work  on  the 
following  topics:  “The  Aurochs,”  “Wild  Cattle  of  the  Scottish  High- 

lands,” “The  Buffaloes  of  the  Orient,”  “The  American  Bison,”  “The 
Cow-boys  of  the  West  and  their  Work  with  their  Herds,”  “The  Breeds  of 
Beef  Cattle,  Where  they  Came  From,  and  Where  Developed,”  “The 
Breeds  of  Milch  Cattle,  their  Origin  and  Names.”  The  following  ques- 
tions may  be  given  out  a few  at  a time  and  answered  as  the  pupils  have 
opportunity  for  observation. 

Observations — 1 . What  are  the  characteristics  of  a fine  cow  ? Describe 
her  horns,  ears,  eyes,  nose  and  mouth.  Do  you  think  she  can  hear  well? 
What  is  the  attitude  of  her  ears  when  she  is  listening?  Do  you  think  she 
has  a keen  sense  of  smell ? Is  her  nose  moist?  Is  her  hair  long  or  short ? 
Smooth  or  rough  ? 

2.  The  cow  walks  on  two  toes.  Can  you  see  any  other  toes  which  she 
does  not  walk  on  ? Why  is  the  cow’s  foot  better  adapted  than  that  of  the 
horse,  to  walk  in  mud  and  marshes?  What  do  we  call  the  two  hind  toes 
which  she  does  not  walk  on?  Can  you  point  out  on  the  cow’s  leg  those 
parts  which  correspond  with  our  elbow,  wrist,  knee  and  ankle?  Is  the 
cow  a good  runner?  Is  she  a good  jumper?  Can  she  swim?

3.  For  what  use  was  the  cow’s  tail  evidently  intended?  How  do  the 
wild  buffalos  and  bisons  get  rid  of  attacks  of  flies? 

4.  How  much  of  cattle  language  do  you  understand?  How  does  the 
cow  express  pleasure?  Lonesomeness?  Anger?  How  does  the  bull 
express  anger?  What  does  the  calf  express  with  the  voice? 

5.  Is  there  always  a leader  in  a herd  of  cows?  Do  certain  cows  of 
the  herd  always  go  first  and  others  last?  Do  the  cows  readily  learn  to 
take  each  her  own  place  in  the  stable?  How  is  leadership  of  the  herd 
attained  ? Describe  cattle  at  play. 

6.  At  what  time  of  day  do  cattle  feed  in  the  pasture?  When  and 
where  do  they  chew  the  cud  ? Do  they  stand  or  lie  to  do  this  ? Describe 
how  a cow  lies  down  and  gets  up. 

7 . How  do  wild  cattle  defend  themselves  from  wolves  ? From  bears 
or  other  solitary  animals? 

8.  For  what  purposes  were  cattle  first  domesticated?  For  how 
many  purposes  do  we  rear  cattle  today? 

9.  Name  and  give  brief  descriptions  of  the  different  breeds  of  cattle 
with  which  you  are  familiar.  Which  of  these  are  beef  and  which  milch 
types  ? 

10.  What  are  the  distinguishing  points  of  a good  milch  cow?  Of  a 
good  beef  animal?  What  does  the  food  do  for  each  of  these?  Which 
part  of  the  United  States  produces  most  beef  cattle?  Which  the  most 
milch  cattle? 

1 1 . What  do  we  mean  by  a balanced  ration  ? Do  you  know  how  to 
compute  one?  What  is  the  advantage  of  feeding  cattle  a balanced 
ration  ? 

12.  How  many  pounds  of  milk  should  a dairy  cow  produce  in  a year 
to  be  profitable  if  the  product  is  cheese?  If  the  product  is  butter?  Why 
this  discrepancy?  What  must  be  the  percent,  of  butter  fat  in  milk  to 
make  it  legally  salable  in  your  state?  How  many  months  of  the  year 
should  a good  cow  give  milk? 

13.  Why  should  a cow  be  milked  always  by  the  same  person  ? Does 
the  milker  always  sit  on  the  same  side?  Why  should  loud  talking  and 
other  noise  at  milking  time  be  avoided  ? Should  a dog  be  used  in  driving 
dairy  cows  ? Why  ? 

14.  Why  is  a cool  draughty  bam  an  expensive  place  in  which  to  keep 
cattle?  Why  is  a bam  not  well-ventilated,  a danger? 

15.  Why  and  where  is  the  dehorning  of  cattle  practiced?  When  and 
how  should  a calf  be  dehorned? 

16.  Why  should  milk  not  be  strained  in  the  bam?  Why  is  it  profit- 
able for  the  dairy  farmer  to  keep  his  stable  clean  and  to  be  cleanly  in  the 
care  of  milk?  How  does  the  food  of  cows  affect  the  flavor  of  the  milk? 
Why  should  a farmer  keep  a record  of  the  number  of  pounds  of  milk  which 
each  cow  in  his  dairy  gives  each  day? 

1 7 . For  what  are  oxen  used  ? Wherein  are  they  superior  to  horses 
as  draft  animals?  Do  you  know  of  any  place  where  oxen  are  used  as 
riding  animals  ? 

18.  How  many  industries  are  dependent  upon  cattle? 

19.  Give  oral  or  written  exercises  on  the  following  themes : “How 

the  Best  Butter  is  Made;”  “The  Use  of  Bacteria  in  Butter;”  “How  Dairy 
Cheese  is  Made;”  “How  Fancy  Cheeses  are  Made.”

THE  PIG 

Teacher's  Story 

S‘I  wander  through  the  underbresh, 

Where  pig  tracks  pmtin'  to'rds  the  crick , 

Is  picked  and  printed  in  the  fresh 
Black  bottom-lands , like  wimmen  prick 
Their  pie-crust  with  a fork." — Riley. 

Y a forest  law  of  William  the  First  of  England  in  the 
eleventh  century,  it  was  ordained  that  any  that  were 
found  guilty  of  killing  the  stag  or  the  roebuck  or  the 
wild  boar,  should  have  their  eyes  put  out.  This  shows 
that  the  hunting  of  the  wild  boar  in  England  was 
considered  a sport  of  gentlemen  in  an  age  when  nothing 
was  considered  sport  unless  it  was  dangerous.  The 
wild  hog  of  Europe  is  the  ancestor  of  our  common 
domesticated  breeds;  although  independent  of  these,  the  Chinese  domes- 
ticated their  own  wild  species,  even  before  the  dawn  of  history. 

The  wild  hog  likes  damp  situations  where  it  may  wallow  in  the  water 
and  mud;  but  it  also  likes  to  have,  close  by,  woods,  thicket  or  under- 
brush, to  which  it  can  retire  for  rest  and  also  when  in  danger.  The  stiff, 
bristling  hairs  which  cover  its  thick  skin,  are  a great  protection  when  it  is 
pushing  through  thorny  thickets.  When  excited  or  angry,  these  bristles 
rise  and  add  to  the  fury  of  its  appearance.  Even  in  our  own  country, 
the  wild  hogs  of  the  South  whose  ancestors  escaped  from  domestication, 
have  reverted  to  their  original  savagery,  and  are  dangerous  when  infuri- 
ated. The  only  recorded  instance  when  our  great  national  hunter,  Theo- 
dore Roosevelt,  was  forced  ignominiously  to  climb  a tree,  was  after  he

had  emptied  his  rifle  into  a herd  of  “javelins,”  as  the  wild  pigs  of  Texas 
are  called;  the  javelins  are  the  peccaries,  which  are  the  American  repre- 
sentatives of  the  wild  hog. 

That  the  hog  has  become  synonymous  with  filth  is  the  result  of  the 
influence  of  man  upon  this  animal,  for  of  all  animals,  the  pig  is  naturally 
the  neatest,  keeping  its  bed  clean,  often  in  the  most  discouraging  and  ill- 
kept  pens.  The  pig  is  sparsely  clothed  with  bristles  and  hairs,  which 
yield  it  no  protection  from  the  attacks  of  flies  and  other  insects.  Thus  it 
is  the  pig,  in  order  to  rid  itself  of  these  pests,  has  learned  to  wallow  in  the 
mud.  However,  this  is  in  the  nature  of  a mud  bath,  and  is  for  the  pur- 
pose of  keeping  the  body  free  from  vermin.  The  wild  hogs  of  India  make 
for  themselves  grass  huts,  thatched  above  and  with  doors  at  the  sides, 
which  shows  that  the  pig,  if  allowed  to  care  for  itself,  understands  well 
the  art  of  nest-building. 

One  of  the  most  interesting  things  about  a pig,  is  its  nose;  this  is  a 
fleshy  disc  with  nostrils  in  it  and  is  a most  sensitive  organ  of  feeling;  it 
can  select  grain  from  chaff,  and  yet  is  so  strong  that  it  can  root  up  the 
ground  in  search  for  food.  “Root”  is  a pig  word,  and  was  evidently 
coined  to  describe  the  act  of  the  pig  when  digging  for  roots ; the  pig’s  nose 
is  almost  as  remarkable  as  the  elephant’s  trunk,  and  the  pig’s  sense  of 
smell  is  very  keen ; it  will  follow  a track  almost  as  well  as  a dog.  There 
are  more  instances  than  one  of  a pig  being  trained  as  a pointer  for  hunting 
birds,  and  showing  a keener  sense  of  smell,  and  keener  intelligence  in 
this  capacity,  than  do  dogs.  French  pigs  are  taught  to  hunt  for  truffles, 
which  are  fungi  growing  on  tree  roots,  a long  way  below  the  surface  of  the 
ground;  the  pig  detects  their  presence  through  the  sense  of  smell. 

The  pig  has  a full  set  of  teeth,  having  six  incisors,  two  canines  and 
seven  grinding  teeth  on  each  jaw;  although  in  some  cases  there  are  only 
four  incisors  on  the  upper  jaw.  A strange  thing  about  a pig’s  teeth,  is  the 
action  of  the  upper  canines,  or  tushes,  which  curve  upward  instead  of 
downward;  the  lower  canines  grind  up  against  them,  and  are  thus 
sharpened.  The  females  have  no  such  development  of  upper  tushes  as 
do  the  males;  these  tushes,  especially  the  upper  ones,  are  used  as  weapons; 
with  them,  the  wild  boar  slashes  out  and  upward,  inflicting  terrible 
wounds,  often  disabling  horses  and  killing  men.  Professor  H.  F.  Button 
describes  the  fighting  of  hogs  thus:  “To  oppose  the  terrible  weapons  of 

his  rival,  the  boar  has  a shield  of  skin  over  his  neck  and  shoulders,  which 
may  become  two  inches  thick,  and  so  hard  as  to  defy  a knife.  When  two 
of  these  animals  fight,  each  tries  to  keep  the  tushes  of  his  opponent  against 
the  shield,  and  to  get  his  own  tushes  under  the  belly  or  flank  of  the  other. 
Thus,  each  goes  sidewise  or  in  circles,  which  has  given  rise  to  the  expres- 
sion, ‘to  go  sidewise  like  a hog  to  war.’  ” 

When,  as  a small  girl,  I essayed  the  difficult  task  of  working  button- 
holes, I was  told  if  I did  not  set  my  stitches  more  closely  together,  my 
buttonhole  would  look  like  a pig’s  eye,  a remark  which  made  me  observant 
of  that  organ  ever  after.  But  though  the  pig’s  eyes  are  small,  they  cer- 
tainly gleam  with  intelligence,  and  they  take  in  all  that  is  going  on, 
which  may  in  any  way  affect  his  pigship. 

The  pig  is  the  most  intelligent  of  all  the  farm  animals,  if  it  is  only  given 
a chance ; it  has  excellent  memory  and  can  be  taught  tricks  readily ; it  is 
affectionate  and  will  follow  its  master  around  like  a dog.  Anyone  who 
has  seen  a trained  pig  at  a show  picking  out  cards  and  counting,  must 


Mammal  Study

grant  that  it  has  brains,  although  we  stuff  it  so  with  fattening  food,  that 
it  does  not  have  a chance  to  use  its  brain,  except  now  and  then  when  it 
breaks  out  of  the  sty  and  we  try  to  drive  it  back.  Under  these  circum- 
stances, we  grant  the  pig  all  the  sagacity  usually  imputed  to  the  one  who 
once  possessed  swine  and  drove  them  into  the  sea.  Hunters  of  wild  hogs 
proclaim  that  they  are  full  of  strategy  and  cunning,  and  are  exceedingly 
fierce.  We  pay  tribute  to  the  pig’s  cleverness  when  free  to  outwit  us, 
when  we  say  of  other  uncertain  undertakings,  that  they  are  like  “buying 
a pig  in  a poke.” 

The  head  of  the  wild  hog  is  wedge-shaped  with  pointed  snout,  and  this 
form  enables  the  animal  to  push  into  the  thick  underbrush  along  the  river 
banks,  whenever  it  is  attacked. 

But  civilization  has  changed  this 
bold  profile  of  the  head,  so  that 
now  in  many  breeds,  there  is  a 
hollow  between  the  snout  and 
eyes,  giving  the  form  which  we 
call  “dished.”  Some  breeds  have 
sharp,  forward-opening  ears,  while 
others  have  ears  that  lop.  The 
wild  pig  of  Europe  and  Asia  has 
large,  open  ears  extending  out 
wide  and  alert  on  each  side  of  the 
head. 

The  covering  of  the  pig  is  a 
thick  skin  beset  with  bristling 
hairs;  when  the  hog  is  excited, 
the  bristles  rise  and  add  to  the 
fury  of  its  appearance.  The  bris- 
tles aid  in  protecting  the  animal 
when  it  is  pushing  through  thorny 
thickets.  The  pig’s  querly  tail  is  merely  an  ornament,  although  the 
tail  of  the  wart  hog  of  Africa,  if  pictures  may  be  relied  upon,  might  be 
used  in  a limited  fashion  as  a fly-brush. 

When  the  pig  is  allowed  to  roam  in  the  woods,  it  lives  on  roots,  nuts, 
and  especially  acorns  and  beech  nuts ; in  the  autumn  it  becomes  very  fat 
through  feeding  upon  the  latter.  The  mast-fed  bacon  of  the  semi- wild 
hogs  of  the  Southern  States  is  considered  the  best  of  all.  But  almost  any- 
thing animal  or  vegetable,  that  comes  in  its  way,  is  eaten  by  the  hog,  and 
it  has  been  long  noted  that  the  hog  has  done  good  service  on  our  frontier 
as  a killer  of  rattlesnakes.  The  pig  is  Veil  fitted  for  locomotion  on  either 
wet  or  dry  soil,  for  the  two  large  hoofed  toes  enable  it  to  walk  well  on  dry 
ground  and  the  two  hind  toes,  smaller  and  higher  up,  help  to  sustain  it  on 
marshy  soil.  Although  the  pig’s  legs  are  short,  it  is  a swift  runner  unless 
it  is  too  fat.  The  razor-backs  of  the  South  are  noted  for  their  fleetness. 

We  understand  somewhat  the  pig’s  language;  there  is  the  constant 
grunting,  which  is  a sound  that  keeps  the  pig  herd  together.  We  under- 
stand perfectly  the  complaining  squeal  of  hunger,  the  satisfied  grunt 
signifying  enjoyment  of  food,  the  squeal  of  terror  when  seized,  and  the 
nasal  growl  when  fighting.  But  there  is  much  more  to  the  pig’s  conversa- 
tion than  this;  I know  a certain  lady,  who  is  a lover  of  animals,  and  who 
once  undertook  to  talk  pig  language  as  best  she  could  imitate  it,  to  two  of 


3°6 


Handbook  of  Nature-Study 


her  sows  when  they  were  engaged  in  eating.  They  stopped  eating,  looked 
at  each  other  a moment  and  forthwith  began  fighting,  each  evidently 
attributing  the  lady’s  remark  to  the  other,  and  obviously  it  was  of  an 
uncomplimentary  character. 

The  pig’s  ability  to  take  on  fat  was  evidently  a provision,  in  the  wild 
state,  for  storing  up  fat  from  mast  that  should  help  sustain  the  animal 
during  the  hardships  of  winter ; and  this  character  is  what  makes  swine 
useful  for  our  own  food.  Pigs,  to  do  best,  should  be  allowed  to  have 
pasture  and  plenty  of  fresh  green  food.  Their  troughs  should  be  kept 
clean  and  they  should  have  access  to  ashes,  and  above  all,  they  should 
have  plenty  of  pure  water;  and  as  the  pig  does  not  perspire  freely,  access 
to  water  where  it  can  take  its  natural  mud-baths  helps  to  keep  the  body 
cool  and  the  pig  healthy  in  hot  weather. 

The  breeds  of  hogs  most  common  in  America  are  the  Berkshires,  which 
are  black  with  white  markings,  and  have  ears  extending  erect;  the 
Poland  Chinas,  which  are  black  and  white  with  drooping  ears;  the  Duroc- 
Jersey,  which  are  red  or  chestnut  with  drooping  ears ; the  Yorkshire  and 
Cheshire,  which  are  white  with  erect  ears,  while  the  Cheshire  White  is 
white  with  drooping  ears.  The  Poland  China  and  Duroc- Jersey  are  both 
pure  American  breeds.

LESSON  LXIX 
The  Pig 

Leading  thought — The  pig  is  something  more  than  a source  of  pork. 
It  is  a sagacious  animal  and  naturally  cleanly  in  its  habits  when  not  made 
prisoner  by  man. 

Method — The  questions  in  this  lesson  may  be  given  to  the  pupils  a few 
at  a time,  and  those  who  have  access  to  farms  or  other  places  where  pigs 

are  kept  may  make 
the  observations  and 
in  giving  them  to  the 
class  they  should  be 
discussed.  Supple- 
mentary reading 
should  be  given  the 
pupils,  which  may  in- 
form them  as  to  the 
habits  and  peculiari- 
ties of  the  wild  hogs. 
Theodore  Roosevelt’s 
experience  in  hunting 
the  wart-hog  in  Africa 
will  prove  interesting 
reading.

of  other  animals?  What  is  it  used  for  besides  for  smelling?  Do  you 
think  the  pig’s  sense  of  smell  is  very  keen?  Why  do  pigs  root? 

2.  Describe  the  pig’s  teeth.  For  what  are  they  fitted?  What  are 
the  tushes  for?  Which  way  do  the  upper  tushes  turn?  How  do  wild 
hogs  use  their  tushes  ? 

3.  Do  you  think  that  a pig’s  eyes  look  intelligent?  What  color  are 
they?  Do  you  think  the  pig  can  see  well? 

4.  Is  the  pig’s  head  straight  in  front  or  is  it  dished?  Is  this  dished 
appearance  ever  found  in  wild  hogs?  Do  the  ears  stand  out  straight  or 
are  they  lopped?  What  advantage  is  the  wedge-shaped  head  to  the  wild 
hogs? 

5.  How  is  the  pig  covered?  Do  you  think  the  hair  is  thick  enough  to 
keep  off  flies?  Why  does  the  pig  wallow  in  the  mud?  Is  it  because  the 
animal  is  dirty  by  nature  or  because  it  is  trying  to  keep  clean  ? Do  the 
hog’s  bristles  stand  up  if  it  is  angry? 

6.  If  the  pig  could  have  its  natural  food  what  would  it  be  and  where 
would  it  be  found  ? Why  and  on  what  should  pigs  be  pastured  ? What 
do  pigs  find  in  the  forest  to  eat?  What  kind  of  bacon  is  considered  the 
best? 

7.  On  how  many  toes  does  the  pig  walk?  Are  there  other  toes  on 
which  it  does  not  walk?  If  wading  in  the  mud  are  the  two  hind  toes  of 
use  ? Do  wild  pigs  run  rapidly  ? Do  tame  pigs  run  rapidly  if  they  are  not 
too  fat  ? Do  you  think  the  pig  can  swim  ? Do  you  think  that  the  pig’s 
tail  is  of  any  use  or  merely  an  ornament? 

8.  What  cries  and  noises  do  the  pigs  make  which  we  can  understand? 

9 . How  do  hogs  fight  each  other  ? When  the  boars  fight , how  do  they 
attack  or  ward  off  the  enemy  ? Where  do  we  get  the  expression  going 
‘‘sidewise  like  a hog  to  war?” 

10.  How  many  breeds  of  pigs  do  you  know?  Describe  them. 

11.  What  instances  have  you  heard  that  show  the  hog’s  intelligence? 

12.  Give  an  oral  or  written  English  exercise  on  one  of  the  following 

topics : “The  antiquity  of  swine ; how  they  were  regarded  by  the  ancient 

Egyptians,  Greeks  and  Romans;”  (see  encyclopedia).  “The  story  of 
hunting  wild  hogs  in  India;  “The  razor-back  hogs  of  the  South;”  “The 
wart-hog  of  Africa.” 


“The  nice  little  pig  with  a querly  tail.

VI.  INSECT  STUDY 


1 NSECTS  are  among  the  most  interesting  and  available  of 
all  living  creatures  for  nature-study.  The  lives  of 
many  of  them  afford  more  interesting  stories  than  are 
found  in  fairy  lore ; many  of  them  show  exquisite  colors 
and,  more  than  all,  they  are  small  and  are,  therefore, 
easily  confined  for  observation. 

While  the  young  pupils  should  not  be  drilled  in 
insect  anatomy,  as  if  they  were  embryo  zoologists,  yet  it 
is  necessary  for  the  teacher,  who  would  teach  intelli- 
gently, to  know  something  of  the  life  stories,  habits  and 
structure  of  the  common  insects.  Generally  speaking, 
all  insects  develop  from  eggs.  To  most  of  us  the 
word  egg  brings  before  us  the  picture  of  the  egg  of  the  hen  or  of  some 
other  bird.  But  insect  eggs  are  often  far  more  beautiful  than  those  of  any 
bird;  they  are  of  widely  differing  forms,  and  are  often  exquisitely  colored 
and  the  shells  may  be  ornately  ribbed  and  pitted,  sometimes  adorned 
with  spines,  and  are  as  beautiful  to  look  at  through  a microscope  as  the 
most  artistic  piece  of  mosaic. 

From  the  eggs,  larvae  {sing,  larva)  issue.  These  larvae  may  be 
caterpillars,  or  the  creatures  commonly  called  worms,  or  may  be  maggots

or  grubs.  The  larval  stage  is  always  devoted  to  feeding  and  to  growth. 
It  is  the  chief  business  of  the  larva  to  eat  diligently  and  to  attain  maturity 
as  soon  as  possible;  for  often  the  length  of  the  larval  period  depends 
more  upon  food  than  upon  lapse  of  time.  All  insects  have  their  skele- 
tons on  the  outside  of  the  body ; that  is,  the  outer  covering  of  the  body  is 
chitinous,  and  the  soft  and  inner  parts  are  attached  to  it  and  supported

by  it.  This  skin  is  so 
firm  that  it  cannot  stretch 
to  accommodate  the  in- 
creasing size  of  the  grow- 
ing insect,  thus  from  time 
to  time  it  is  shed.  But 
before  this  is  done,  a new 
skin  is  formed  beneath 
the  old  one.  After  the 
old  skin  bursts  open  and 
the  insect  c'rawls  forth, 
the  new  skin  is  sufficiently 
soft  and  elastic  to  allow 
for  the  increase  in  the 
size  of  the  insect.  Soon, 
the  new  skin  becomes 
hardened  like  the  old  one, 
and  after  a time,  is  shed. 
This  shedding  of  the  skin 
is  called  molting.  Some  insects  shed'  their  skins  only  four  or  five  times 
during  the  period  of  attaining  their  growth,  while  other  species  may  molt 
twenty  times  or  more. 

After  the  larva  has  attained  its  full  growth,  it  changes  its  skin  and  its 
form,  and  becomes  a pupa.  The  pupa  stage  is  ordinarily  one  of  inaction, 
except  that  very  wonderful  changes  take  place  within  the  body  itself. 
Usually  the  pupa  has  no  power  of  moving  around,  but  in  many  cases  it 
can  squirm  somewhat,  if  disturbed.  Th^^upa^of  the  mosquito  is  active 
and  is  an  exception  to  the  rule.  The  pupa  is  usually  an  oblong  object 
and  seems  to  be  without  head,  feet  or  wings;  but  if  it  is  examined  closely, 
especially  in  the  case  of 
butterflies  and  moths,  the 
antennae,  wings  and  legs 
may  be  seen,  folded  down 
beneath  the  pupa  skin. 

Many  larvae,  especially 
those  of  moths,  weave 
about  themselves  a cover- 
ing of  silk  which  serves  to 
protect  them  from  their 
enemies  and  the  weather, 
during  the  helpless  pupa 
period.  This  silken  cover- 
ing is  called  a cocoon. 

The  larvae  of  butterflies 
do  not  make  a silken 
cocoon,  but  the  pupa  is 
suspended  to  some  object 
by  a silken  knob,  and  in 
some  cases  by  a halter  of 
silk,  and  remains  entirely  naked.  The  pupa  of  a butterfly  is  called  a 
chrysalis.  Care  should  be  taken  to  have  the  children  use  the  words — 
pupa,  chrysalis  and  cocoon — understanding^.

After  a period  varying  from  days  to  months,  depending  upon  the 
species  of  insect  and  the  climate,  the  pupa  skin  bursts  open  and  from  it 

emerges  the  adult  insect,  often 
equipped  with  large  and  beautiful 
wings  and  always  provided  with 
six  legs  and  a far  more  complex 
structure  of  body  than  character- 
ized it  as  a larva.  The  insect  never 
grows  after  it  reaches  this  adult 
stage  and,  therefore,  never  molts.

the  “ Empress  of  the  night” . The  long  swallow  tail  of  the  hind  wings  give  the  moth  a most  graceful  shape,  at 
the  same  time  probably  afford  it  protection  from  observation.  During  the  day  time  the  moth  hangs  wings 
down  beneath  the  green  leaves,  and  these  long  projections  of  the  hind,  wings  folded  together  resemble  a

perfect  wings,  it  does  not  grow  larger.  Many  adult  insects  take  very 
little  food,  although  some  continue  to  eat  in  order  to  support  life.  The 
adult  stage  is  ordinarily  shorter  than  the  larval  stage ; it  seems  a part  of 
nature’s  economic  plan  that  the  grown-up  insects  should  live  only  long 
enough  to  lay  eggs,  and  thus  secure  the  continuation  of  the  species. 
Insects  having  the  four  distinct  stages  in  their  growth,  egg,  larva,  pupa 
and  adult,  are  said  to  undergo  complete  metamorphosis. 

But  not  all  insects  pass  through  an  inactive  pupa  stage.  With  some 
insects,  like  the  grasshoppers,  the  young,  as  soon  as  they  are  hatched, 
resemble  the  adult  forms  in  appearance.  These  insects,  like  the  larvae, 
shed  their  skins  to  accommodate  their  growth,  but  they  continue  to  feed 
and  move  about  actively  until  the  final  molt  when  the  perfect  insect 
appears.  Such  insects  are  said  to  have  incomplete  metamorphosis, 
which  simply  means  that  the  form  of  the  body  of  the  adult  insect  is 
not  greatly  different  from  that  of  the  young;  the  dragon-flies,  crickets, 
grasshoppers  and  bugs  are  of  this  type.  The  young  of  insects  with  an 
incomplete  metamorphosis  are  called  nymphs  instead  of  larvae.

The  Structure  of  Insects 

The  insect  body  is  made  up  of  ring-like  segments  which  are  grown 
together.  These  segments  are  divided  into  groups  according  to  their  use 
and  the  organs  which  they  bear.  Thus  the  segments  of  an  insect’s  body 
are  grouped  into  three  regions,  the  head,  the  thorax  and  the  abdomen. 
The  head  bears  the  eyes,  the  antennas,  and  the  mouth-parts.  On  each 
side  of  the  head  of  the  adult  insect  may  be  seen  the  compound  eyes;  these 
are  so  called,  because  they  are  made  up  of  many  small 
eyes  set  together,  much  like  the  cells  of  the  honeycomb. 
These  compound  eyes  are  not  found  in  larvae.  In  addi- 
tion to  the  compound  eyes,  many  adult  insects  possess 
simple  eyes;  these  are  placed  between  the  compound 
eyes  and  are  usually  three  in  number.  Often  they 
cannot  be  seen  without  the  aid  of  a lens. 

The  antennas  or  feelers  are  composed  of  many  seg- 
ments and  are  inserted  in  front  of  the  eyes  or  between 
them.  They  vary  greatly  in  form.  In  some  insects 
they  are  mere  threads;  in  others,  like  the  silk- worm 
moths,  they  are  large,  feather-like  organs. 

The  mouth-parts  of  insects  vary  greatly  in  structure  and  in  form, 
being  adapted  to  the  life  of  the  insect  species  to  which  they  minister. 
Some  insects  have  jaws  fitted  for  seizing  their  prey,  others  for  chewing

leaves,  others  have  a sucking  tube  for 
getting  the  juices  from  plants  or  the 
blood  from  animals,  and  others  long 
delicate  tubes  for  sipping  the  nectar 
from  flowers. 

In  the  biting  insects,  the  mouth- 
parts  consist  of  an  upper  lip,  the  labrum, 
and  under  lip,  the  labium,  and  two 
pairs  of  jaws  between  them.  The  upper 
pair  of  jaws  is  called  the  mandibles  and 
the  lower  pair,  the  maxillae  (sing, 
maxilla).  There  may  be  also  within 
the  mouth,  one  or  two  tongue-like 
organs.  Upon,  the  maxillae  and  upon 
the  lower  lip  there  may  also  be  feelers 
which  are  called  palpi  (sing,  palpus).

able  to  observe  the  mandibles  and  the  palpi 
without  the  aid  of  a lens. 

The  thorax  is  the  middle  region  of  the  insect 
body.  It  is  composed  of  three  of  the  body  seg- 
ments more  or  less  firmly  joined  together.  The 
segment  next  the  head  is  called  the  prothorax,  the 
middle  one,  the  mesothorax,  and  the  hind  one,  the 
metathorax.  Each  of  these  segments  bears  a 
pair  of  legs  and,  in  the  winged  insects,  the  second 
and  third  segments  bear  the  wings.  Each  leg 

consists  of  two  small  segments  next 
to  the  body,  next  to  them  a longer 
segment,  called  the  femur,  beyond 
this  a segment  called  the  tibia,  and 
beyond  this  the  tarsus  or  foot.  The 
tarsus  is  made  up  of  a number  of 
segments,  varying  from  one  to  six, 
the  most  common  number  being 
five.  The  last  segment  of  the  tarsus 
usually  bears  one  or  two  claws. 

While  we  have  little  to  do  with 
the  internal  anatomy  of  insects  in 
elementary  nature-study,  the  chil- 
dren should  be  taught  something  of 
the  way  that  insects  breathe.  The 
child  naturally  believes  that  the 
insect,  like  himself,  breathes  through 
the  mouth,  while  as  a matter  of  fact, 
insects  breathe  through  their  sides. 
If  we  examine  almost  any  insect 
carefully,  we  can  find  along  the  sides 
of  the  body  a series  of  openings. 
These  are  called  the  spiracles,  and

through  them  the  air  passes  into  the  insect’s  body.  The  number 
of  spiracles  varies  greatly  in  different  insects.  There  is,  however, 
never  more  than  one  pair  on  a single  segment  of  the  body,  and  they  do 
not  occur  on  the  head.  The  spiracles,  or  breathing  pores,  lead  into  a 
system  of  air  tubes  which  are  called  tracheae  (tra'-ke-ee) , which  permeate 
the  insect’s  body  and  thus  carry  the  air  to  every  smallest  part  of  its 
anatomy.  The  blood  of  the  insect  bathes  these  thin-walled  air  tubes 
and  thus  becomes  purified,  just  as  our  blood  becomes  purified  by  bathing 
the  air  tubes  of  our  lungs.  Thus,  although  the  insects  do  not  have 
localized  breathing  organs,  like  our  lungs,  they  have,  if  the  expression 
may  be  permitted,  lungs  in  every  part  of  their  little  bodies.

THE  BLACK  SWALLOW-TAIL  BUTTERFLY 

Teacher's  Story 

HIS  graceful  butterfly  is  a very  good  friend  to  the 
flowers,  being  a most  efficient  pollen  carrier.  It 
haunts  the  gardens  and  sips  nectar  from  all  the  blossom 
cups  held  out  for  its  refreshment;  and  it  is  found 
throughout  almost  all  parts  of  the  United  States. 
The  grace  of  its  appearance  is  much  enhanced  by  the 
“swallow-tails,”  two  projections  from  the  hind  mar- 
gins of  the  hind  wings.  The  wings  are  velvety  black 
with  three  rows  of  yellow  spots  across  them,  the  outer 
row  being  little  crescents  set  in  the  margin  of  the  wing; 
hnd  each  triplet  of  yellow  spots  is  in  the  same  cell  of  the  wing 
between  the  same  two  veins.  The  hind  wings  are  more  elaborate, 
for  between  the  two  inside  rows  of  yellow  spots,  there  are  exquisite 
metallic  blue  splashes,  more  vivid  and  more  sharply  outlined  toward 
the  inside  of  the  wing  and  shading  off  to  black  at  the  outside.  And 
just  above  the  inner  angle  of  the  hind  wing  is  an  orange  eye-spot  with 
a black  center.  On  the  lower  surface  of  the  wings,  most  of  the  yellow 
spots  are  replaced  with  orange. 

The  mother  butterfly  is  larger  than  her  mate  and  has  more  blue  on  her 
wings,  while  he  has  the  yellow  markings  of  the  hind  wings  much  more 
conspicuous.  She  lays  her  egg,  just  the  color  of  a drop  of  honey,  on  the 
under  surface  of  the  leaf  of  the  food  plant. 

After  about  ten  days  there  hatches  from  this 
egg  a spiny  little  fellow,  black  and  angular, 
with  a saddle-shaped,  whitish  blotch  in  the 
middle  of  its  back.  But  it  would  take  an 
elfin  rider  to  sit  in  this  warty,  spiny  saddle. 

The  caterpillar  has  six  spines  on  each  segment, 
making  six  rows  of  spines,  the  whole  length 
of  the  body;  the  spines  on  the  black  portions 
are  black  and  those  on  the  saddle  white,  but 
they  all  have  orange-colored  bases. 

When  little,  spiny  saddle-back  gets  ready 
to  change  its  skin  to  one  more  commodious 
for  its  increased  size,  it  seeks  some  convenient 
spot  on  the  leaf  or  stem  and  spins  a little 
silken  carpet  from  the  silk  gland  opening  in 
its  under  lip;  on  this  carpet  it  rests  quietly 
for  some  time,  and  then  the  old  tight  skin  The  eggs  of  the  black  swallow-

off  separately.  Swelling  out  to  fill  its  new  Phot°'misriingeriandr  M‘  V‘ 
skin  to  the  utmost,  it  leaves  its  cast-off  clothes 
clinging  to  the  silken  carpet  and  marches  back  to  its  supper. 

But  after  one  of  these  changes  of  skin  it  becomes  a very  different 
looking  caterpillar,  for  now  it  is  as  smooth  as  it  was  formerly  spiny;  it  is 
now  brilliant  caraway  green,  ornamented  with  round  wise  stripes  of 
velvety  black;  and  set  in  the  front  margin  of  each  of  these  stripes  are  six 
yellow  spots.  In  shape,  the  caterpillar  is  larger  toward  the  head; 
its  true  feet  have  little , sharp  claws  and  look  very  different  from  the

four  pairs  ot  prolegs  and  the  hind 
prop-leg,  all  of  which  enable  him 
to  hold  fast  to  the  stem  or  the  leaf; 
these  fat  legs  are  green,  each 
ornamented  with  a black,  velvety 
polka-dot. 

When  we  were  children  we  spent 
hours  poking  these  interesting 
creatures  with  straws  to  see  them 
push  forth  their  brilliant  orange 
horns.  We  knew  this  was  an  act 
of  resentment,  but  we  did  not 
realize  that  from  these  horns  was 
exhaled  the  nauseating  odor  of 
caraway  which  greeted  our  nostrils. 

We  incidentally  discovered  that 
they  did  not  waste  this  odor  upon 
each  other,  for  once  we  saw  two  of 
the  full-grown  caterpillars  meet  on 
a caraway  stem.  Neither  seemed 
to  know  that  the  other  was  there 
until  they  touched ; then  both  drew 
back  the  head  and  butted  each 
other  like  billy-goats,  Whack ! 
whack!  Then  both  turned  labor- 
iously around  and  hurried  off  in  a 
panic. 

The  scent  organs  of  these  caterpillars  are  really  little  Y-shaped  pockets 
in  the  segment  back  of  the  head,  pockets  full  of  this  peculiar  caterpillar 
perfume.  Under  the  stimulus  of  attack,  the  pocket  is  turned  wrong  side 
out  and  pushed  far  out  making  the  “horns,”  and  at  the  same  time  throw- 
ing the  strong  odor  upon  the  air.  This  spoils  the  flavor  of  these  cater- 
pillars as  bird  food,  so  they  live  on  in  serene  peace,  never  hiding  under 
the  leaves  but  trusting,  like  the  skunk,  to  a peculiar  power  of  repelling 
the  enemy. 

We  must  admire  this  caterpillar  for  the  methodical  way  in  which  it 
eats  the  leaf  : Beginning  near  the  base,  it  does  not  burn  its  bridges 

behind  it  by  eating  through  the  midrib,  but  eats  everything  down  to  the 
midrib ; after  it  arrives  at  the  tip  of  the  leaf  it  finishes  midrib  and  all  on 
its  return  journey,  doing  a clean  job,  and  finishing  everything  as  it  moves 
along.  (See  Moths  and  Butterflies,  Dickerson,  p.  42.) 

When  the  caterpillar  has  completed  its  growth,  it  is  two  inches  long; 
it  then  seeks  some  sheltered  spot,  the  lower  edge  of  a clapboard  or  fence 
rail  being  a favorite  place ; it  there  spins  a button  of  silk  which  it  grasps 
firmly  with  its  hind  prop-leg,  and  then,  with  head  up,  or  perhaps 
horizontal,  it  spins  a strong  loop  or  halter  of  silk,  fastening  each  end 
of  it  firmly  to  the  object  on  which  it  rests.  It  thrusts  its  head 
through,  so  that  the  halter  acts  as  a sling  holding  the  insect  from  falling. 
There  it  sheds  its  last  caterpillar  skin,  which  shrinks  back  around  the 
button,  revealing  the  chrysalis  which  is  angular  with  ear-like  projections 
in  front.  Then  comes  the  critical  moment,  for  the  chrysalis  lets  go 
of  the  button  with  its  caterpillar  feet,  and  trusting  to  the  sling  for

LESSON  LXX 

The  Black  Swallow-Tail  Butterfly 

Leading  thought — The  caterpillars  of  the  swallow-tail  butterflies  have 
scent  organs  near  the  head  which  they  thrust  forth  when  attacked,  thus 
giving  off  a disagreeable  odor  which  is  nauseating  to  birds. 

Method — In  September,  bring  into  the  schoolroom  and  place  in  the 
terrarium,  or  breeding  cage,  a caraway  or  parsley  plant  on  which  these 
caterpillars  are  feeding,  giving  them  fresh  food  day  by  day,  and  allow  the 
pupils  to  observe  them  at  recess  and  thus  complete  the  lesson. 

The  Caterpillar  and  Chrysalis. 

Observations. — 1.  Touch  the  caterpillar  on  the  head  with  a bit  of 
grass.  What  does  it  do?  What  color  are  the  horns?  Where  do  they 
come  from  ? Are  there  two  separate  horns  or  two  branches  of  one  horn  ? 
What  odor  comes  from  these  horns?  How  does  this  protect  the  cater- 
pillar? Does  the  caterpillar  try  to  hide  under  the  leaves  when  feeding? 
Is  this  evidence  that  it  is  not  afraid  of  birds  ? 

2.  Describe  the  caterpillar  as  follows:  What  is  its  shape?  Is  it 
larger  toward  the  head  or  the  rear  end ? What  is  its  ground  color?  How 
is  it  striped?  How  many  black  stripes?  How  many  yellow  spots  in  each 


support,  pushes  off  the  shrunken  skin  just  shed  and  inserts  the  hooks, 

with  which  it  is  fur- 
nished, firmly  in  the 
button  of  silk.  Some- 
times during  this  pro- 
cess, the  chrysalis  loses 
its  hold  entirely  and  falls 
to  the  ground,  which  is 
a fatal  disaster.  The 
chrysalis  is  yellowish 
brown  and  usually  looks 
very  much  like  the  ob- 
ject to  which  it  is  at- 
tached, and  is  thus  un- 
doubtedly protected 
from  sight  of  possible 
enemies.  Then  some 
day  it  breaks  open,  and 
from  it  issues  a crumpled 
mass  of  very  damp  insect 
velvet,  which  soon  ex- 
pands into  a beautiful 
butterfly.

The  Butterfly 

1.  Why  is  this  butterfly  called  the  black  swallow-tail?  What  is  the 
ground  color  of  the  wings?  How  many  rows  of  yellow  spots  on  the  front 
wings?  Are  they  all  the  same  shape?  How  are  they  arranged  between 
each  two  veins?  Describe  the  hind  wings.  What  colors  are  on  them 
that  are  not  on  the  front  wings?  Describe  where  this  color  is  placed. 
Describe  the  eye-spot  on  the  hind  wing.  Where  is  it?  How  do  the 
markings  on  the  lower  side  of  the  wing  differ  from  those  above?  How 
does  the  ground  color  differ  from  the  upper  side? 

2.  What  is  the  color  of  the  body  of  the  butterfly?  Has  it  any 
marks?  Has  it  the  same  number  of  legs  as  the  Monarch?  Describe  its 
antennae.  Watch  the  butterfly  getting  nectar  from  the  petunia  blossom 
and  describe  the  tongue.  Where  is  the  tongue  when  not  in  use? 

3.  How  does  the  butterfly  pass  the  winter?  How  does  the  mother 
butterfly  differ  in  size  and  in  markings  from  her  mate? 


“ The  ‘ caraway  worms 1 were  the  ones  that  revealed  to  us  the  mystery  of  the  pupa  and 
butterfly.  We  saw  one  climb  up  the  side  of  a house,  and  watched  it  as  with  many  slow, 
graceful  movements  of  the  head,  it  wove  for  itself  the  loop  of  silk  which  we  called  the  ‘ swing" 
and  which  held  it  in  place  after  it  changed  to  a chrysalis.  We  wondered  why  such  a 
brilliant  caterpillar  should  change  to  such  a dull-colored  object , almost  the  color  of  the 
clapboard  against  which  it  hung.  Then,  one  day,  we  found  a damp,  crumpled,  black 
butterfly  hanging  to  the  empty  chrysalis  skin,  its  wings  ‘ all  mussed ’ as  we  termed  it; 
and  we  gazed  at  it  pityingly;  but  even  as  we  gazed,  the  crumpled  wings  expanded  and 
then  there  came  to  our  childish  minds  a dim  realization  of  the  miracle  wrought  within 
that  little,  dingy,  empty  shell."

The  Monarch  Butterfly 
Teacher's  Story 

T IS  a great  advantage  to  an  insect  to  have  the 
bird  problem  eliminated,  and  the  monarch 
butterfly  enjoys  this  advantage  to  the  utmost. 
Its  method  of  flight  proclaims  it,  for  it  drifts 
about  in  a lazy,  leisurely  manner,  its  glowing 
red  making  it  like  a gleaming  jewel  in  the  air,  a 
very  different  flight  indeed  from  the  zigzag 
dodging  movements  of  other  butterflies.  The 
monarch  has  an  interesting  race  history.  It  is 
a native  of  tropic  America,  and  has  probably 
learned  through  some  race  instinct,  that  by  following  its  food  plant  north 
with  the  opening  season,  it  gains  immunity  from  special  enemies  other 
than  birds,  which  attack  it  in  some  stage  in  its  native  haunts.  Each 
mother  butterfly  follows  the  spring  northward  as  it  advances,  as  far  as  she 
finds  the  milkweed  sprouted. 

There  she  deposits  her  eggs, 
from  which  hatch  individuals 
which  carry  on  the  migration 
as  far  to  the  north  as  possible. 

It  usually  arrives  in  New  York 
State  early  in  July.  As 
cold  weather  approaches,  the 
monarchs  often  gather  in  large 
flocks  and  move  back  to  the 
South.  How  they  find  their 
way  we  cannot  understand, 
since  there  are  among  them 
none  of  the  individuals  which 
pressed  northward  early  in  the 
season. 

The  very  brilliant  copper- 
red  color  of  the  upper  sides  of 
the  wings  of  the  monarch  is 
made  even  more  brilliant  by 
the  contrasting  black  markings 
which  outline  the  veins  and 
border  the  wings,  and  also 
cover  the  tips  of  the  front  wings 
with  a triangular  patch;  this 
latter  seems  to  be  an  especially 
planned  background  for  show- 
ing off  the  pale  orange  and  The  monarch  butterfly. 

white  dots  set  within  it.  There 

are  white  dots  set,  two  pairs  in  two  rows,  between  each  two  veins 
in  the  black  margin  of  the  wings;  and  the  fringe  at  the  edge  of 
the  wings  shows  corresponding  white  markings.  The  hind  wings 
and  the  front  portions  of  the  front  wings  have,  on  their  lower  sides,  a 
ground  color  of  pale  yellow,  which  makes  the  insect  less  conspicuous  when 
it  alights  and  folds  its  wings  above  its  back,  upper  surfaces  together.

The  black  veins,  on  the  lower  surface  of  the  hind  wings,  are  outlined  with 
white,  and  the  white  spots  are  much  larger  than  on  the  upper  surface. 
The  body  is  black,  ornamented  with  a few  pairs  of  white  spots  above  and 
with  many  large  white  dots  below.  The  chief  distinguishing  characteris- 
tic of  insects,  is  the  presence  of  six  legs;  but  in  this  butterfly,  the  front 
legs  are  so  small  that  they  scarcely  look  like  legs. 

It  is  easy  to  observe  the  long,  coiled  tongue  of  the  butterfly.  If  the 
act  is  done  gently,  the  tongue  may  be  uncoiled  by  lifting  it  out  with  a pin. 

To  see  a butterfly  feeding 
upon  nectar,  is  a very  in- 
teresting process  and  may  be 
observed  in  the  garden  almost 
any  day.  I have  also  ob- 
served it  indoors,  by  bringing 
in  petunias  and  nasturtiums 
for  my  imprisoned  butterflies, 
but  they  are  not  so  likely  to 
eat  when  in  confinement. 
The  antennae  are  about  two- 
thirds  as  long  as  the  body  and 
each  ends  in  a long  knob ; this 
knob,  in  some  form,  is  what 
distinguishes  the  antennae  of 
the  butterflies  from  those  of 
moths.  The  male  monarch 
has  a black  spot  upon  one  of 
the  veins  of  the  hind  wing; 
this  is  a perfume  pocket  and 
is  filled  with  what  are  called 
scent  scales;  these  are  scales 
of  peculiar  shape  which  cover 
the  wing  at  this  place  and 
give  forth  an  odor,  which  we 
with  our  coarse  sense  of  smell 
cannot  perceive ; but  the  lady  monarch  is  attracted  by  this  odor.  The 
male  monarch  may  be  described  to  the  children,  as  a dandy  carrying  a 
perfume  pocket  to  attract  his  sweetheart. 

It  is  very  interesting  to  the  pupils  if 
they  are  able  to  see  a bit  of  the  butterfly’s 
wing  through  a three-fourths  objective;  the 
covering  of  scales,  arranged  in  such  perfect 
rows,  is  very  beautiful  and  also  very 
wonderful.  The  children  know  that  they 
get  dust  upon  their  fingers  from  butterflies’ 
wings,  and  they  should  know  that  each 
grain  of  this  dust  is  an  exquisite  scale  with 
notched  edges  and  a ribbed  surface. 

The  monarch  is,  for  some  reason  un- 
known to  us,  distasteful  to  birds,  and  its 
brilliant  colors  are  an  advertisement  to  all  The  scales  on  a butterfly’ s wing ,

alone.  There  is  another  butterfly  called  the  viceroy,  which  has  taken 
advantage  of  this  immunity  from  bird  attack  on  the  part  of  the  monarch 
and  has  imitated  its  colors  in  a truly  remarkable  way,  differing  from 
it  only  in  being  smaller  in  size  and  having  a black  band  across  the 
middle  of  the  hind  wing.  (See  The  Ways  of  the  Six  Footed,  “A  Sheep 
in  Wolf’s  Clothing”). 

The  milkweed  caterpillar,  which  is  the  young  of  the  monarch  butterfly, 
is  a striking  object,  and  when  fully  grown  is  about  two  inches  long.  The 
milkweed  is  a succulent  food  and  the  caterpillar  may  mature  in  eleven 
days;  it  is  a gay  creature,  with  ground 
color  of  green  and  cross  stripes  of 
yellow  and  black.  On  top  of  the 
second  segment,  back  of  the  head,  are 
two  long,  slender  whiplash-like  organs, 
and  on  the  seventh  segment  of  the 
abdomen  is  a similar  pair.  When 
the  caterpillar  is  frightened,  the  whip- 
lashes at  the  front  of  the  body  twitch 
excitedly;  when  it  walks,  they  move 
back  and  forth.  Those  at  the  rear  of 
the  body  are  more  quiet  and  not  so 
expressive  of  caterpillar  emotions. 

These  filaments  are  undoubtedly  of 
use  in  frightening  away  the  little 
parasitic  flies,  that  lay  their  eggs  upon 
the  backs  of  caterpillars;  these  eggs 
hatch  into  little  grubs  that  feed  upon 
the  internal  fatty  portions  of  the 
caterpillar  and  bring  about  its  death 
through  weakness.  I remember  well 
when  I was  a child,  the  creepy  feeling 
with  which  I beheld  these  black  and 
yellow-ringed  caterpillars  waving  and 
lashing  their  whips  back  and  forth  after  I had  disturbed  them;  if  the 
ichneumon  flies  were  as  frightened  as  I,  the  caterpillars  were  surely  safe. 

The  caterpillar  will  feed  upon  no  plant  except  milkweed ; it  feeds  both 
day  and  night,  with  intervals  of  rest,  and  when  resting,  hides  beneath  the 
leaf.  Its  striking  colors  undoubtedly  defend  it  from  birds,  because  it  is 
as  distasteful  to  them  as  is  the  butterfly.  However, 
when  frightened,  these  caterpillars  fall  to  the  ground 
where  their  stripes  make  them  very  inconspicuous 
among  the  grass  and  thus  perhaps  save  them  from 
the  attack  of  animals  less  fastidious  than  birds. 
These  caterpillars,  like  all  others,  grow  by  shedding 
the  skeleton  skin  as  often  as  it  becomes  too  tight. 

The  monarch  chrysalis  is,  I maintain,  the  most 
beautiful  gem  in  Nature’s  jewel  casket;  it  is  an  oblong 
jewel  of  jade,  darker  at  the  upper  end  and  shading  *o 
the  most  exquisite  whitish  green  below;  outlining  thh 
lower  paler  portion  are  shining  flecks  of  gold.  If  we 
look  at  these  gold  flecks  with  a lens,  we  cannot  but 
believe  that  they  are  bits  of  polished  gold-foil.  There

may  be  other  gold  dots  also,  and  outlining  the  apex 
of  the  jewel,  is  a band  of  gold  with  a dotted  lower  edge 
of  jet;'  and  the  knob  at  the  top,  to  which  the  silk 
which  suspends  the  chrysalis  is  fastened,  is  also  jet. 
The  chrysalis  changes  to  a darker  blue-green  after  two 
days,  and  black  dots  appear  in  the  gold  garniture. 
As  this  chrysalis  is  usually  hung  to  the  under  side  of  a 
fence  rail  or  overhanging  rock,  or  to  a leaf,  it  is 
usually  surrounded  by  green  vegetation,  so  that  its 
green  color  protects  it  from  prying  eyes.  Yet  it  is 
hardly  from  birds  that  it  hides;  perhaps  its  little  gilt 
buttons  are  a hint  to  birds  that  this  jewel  is  not 
palatable.  As  it  nears  the  time  for  the  butterfly  to 
emerge,  the  chrysalis  changes  to  a duller  and  darker 
hue.  The  butterfly  emerges  about  twelve  days  after 
the  change  to  a chrysalis.

LESSON  LXXI 
The  Monarch  Butterfly 

Leading  thought — The  monarch  butterfly  migrates  northward,  every 
spring  and  summer,  moving  up  as  fast  as  milkweed  appears,  so  as  to  give 
food  to  its  caterpillar;  and  it  has  often  been  noticed  migrating  back 
southward  in  the  autumn  in  large  swarms.  This  insect  is  distasteful  to 
birds  in  all  its  stages.  Its  chrysalis  is  one  of  the  most  beautiful  objects  in 
all  nature. 

Method — This  lesson  should  be  given  in  September,  while  yet  the 
caterpillars  of  the  monarch  may  be  found  feeding  upon  milkweed,  and 
while  there  are  yet  many  specimens  of  this  gorgeous  butterfly  to  be  seen. 
The  caterpillars  may  be  brought  in,  on  the  food  plant,  and  their  habits 
and  performances  studied  in  the  schoolroom;  but  care  should  be  taken 
not  to  have  the  atmosphere  too  dry. 

The  Butterfly 

Observations-i . How  can  you  tell  the  monarch  butterfly  from  all  others  ? 
What  part  of  the  wings  is  red?  What  portions  are  black?  What  por- 
tions are  white?  What  are  the  colors  and  markings  on  the  lower  side  of 
the  wings?  What  is  the  color  of  the  body  and  how  is  it  ornamented? 

2.  Is  the  flight  of  the  monarch  rapid  or  slow  and  leisurely?  Is  it  a 
very  showy  insect  when  flying  ? Are  its  colors  more  brilliant  in  the  sun- 
shine when  it  is  flying  than  at  any  other  time  ? Why  is  it  not  afraid  of 
birds  ? 

3.  When  the  butterfly  alights,  how  does  it  hold  its  wings?  Do  you 
think  it  is  as  conspicuous  when  its  wings  are  folded  as  when  they  are  open  ? 

4.  Can  you  see  the  butterfly’s  tongue?  Describe  the  antennae. 
How  do  they  differ  from  the  antennae  of  moths?  How  many  legs  has  this 
butterfly?  How  does  this  differ  from  other  insects?  Note  if  you  can  see 
any  indications  of  front  legs. 

5.  Is  there  on  the  butterfly  you  are  studying,  a black  spot  near  one  of 
the  veins  on  each  hind  wing?  Do  you  know  what  this  is?  What  is  it  for? 

6.  Why  are  the  striking  colors  of  this  butterfly  a great  advantage  to 
it  ? Do  you  know  of  any  other  butterfly  which  imitates  it  and  thus  gains 
an  advantage? 

The  Monarch  Caterpillar 

1.  Where  did  you  find  the  Monarch  caterpillar?  Was  it  feeding 
below  or  above  on  the  leaves?  Describe  how  it  eats  the  milkweed  leaf. 

2.  What  are  the  colors  and  the  markings  of  the  caterpillar?  Do  you 
think  these  make  it  conspicuous? 

3.  How  many  whip-lash  shaped  filaments  do  you  find  on  the  cater- 
pillar? On  which  segments  are  they  situated  ? Do  these  move  when  the 
caterpillar  walks  or  when  it  is  disturbed?  Of  what  use  are  they  to  the 
caterpillar? 

4.  Do  you  think  this  caterpillar  would  feed  upon  anything  except 
milkweed?  Does  it  rest,  when  not  feeding,  upon  the  upper  or  the  lower 
surface  of  the  leaves?  Does  it  feed  during  the  night  as  well  as  the  day? 

5.  If  disturbed,  what  does  the  caterpillar  do?  When  it  falls  down 
among  the  grass  how  do  its  cross  stripes  protect  it  from  observation  ? 

6.  Tell  all  the  interesting  things  which  you  have  seen  this  caterpillar 
do. 


Insect  Study 


325 


The  Chrysalis 

1.  When  the  caterpillar  gets  ready  to  change  to  a chrysalis  what  does 
it  do  ? How  does  it  hang  up  ? Describe  how  it  sheds  its  skin. 

2.  Describe  the  chrysalis.  What  is  its  color?  How  and  where  is 
it  ornamented  ? Can  you  see,  in  the  chrysalis,  those  parts  which  cover  the 
wings  of  the  future  butterfly? 

3.  To  what  is  the  chrysalis  attached?  Is  it  in  a position  where  it 
does  not  attract  attention ? How  is  it  attached  to  the  object? 

4.  After  three  or  four  days,  how  does  the  chrysalis  change  in  color? 

Observe,  if  you  can,  the  butterfly  come  out  from  the  chrysalis,  noting  the 
following  points:  Where  does  the  chrysalis  skin  open?  How  does  the 

butterfly  look  when  it  first  comes  out  ? How  does  it  act  for  the  first  two 
or  three  hours  ? How  does  the  empty  chrysalis  skin  look  ? 

A BUTTERFLY  AT  SEA 

Far  out  at  sea — the  sun  was  high , 

While  veered  the  wind  and  flapped  the  sail; 

We  saw  a snow-white  butterfly 
Dancing  before  the  fitful  gale 
Far  out  at  sea. 

The  little  wanderer , who  had  lost 
His  way , of  danger  nothing  knew; 

Settled  a while  upon  the  mast; 

Then  fluttered  o'er  the  waters  blue 
Far  out  at  sea. 

Above , there  gleamed  the  boundless  sky; 

Beneath,  the  boundless  ocean  sheen; 

Between  them  danced  the  butterfly, 

The  spirit-life  of  this  fair  scene, 

Far  out  at  sea. 

The  tiny  soul  that  soared  away, 

Seeking  the  clouds  oh  fragile  wings, 

Lured  by  the  brighter,  purer  ray 

Which  hope's  ecstatic  morning  brings — - 
Far  out  at  sea. 

Away  he  sped,  with  shimmering  glee, 

Scarce  seen,  now  lost,  yet  onward  borne! 

Night  comes  with  wind  and  rain,  and  he 
No  more  will  dance  before  the  morn. 

Far  out  at  sea. 

He  dies,  unlike  his  mates,  I ween. 

Perhaps  not  sooner  or  worse  crossed; 

And  he  hath  felt  and  known  and  seen 
A larger  life  and  hope,  though  lost 
Far  out  at  sea.

THE  ISABELLA  TIGER  MOTH  OR  WOOLLY  BEAR 
T eacher's . Story 

“ Brown  and  furry,  Which  may  he  the  chosen  spot, 

Caterpillar  in  a hurry,  No  toad  spy  you, 

Take  your  walk  Hovering  bird  of  prey  pass  by  you: 

To  the  shady  leaf  or  stalk.  Spin  and  die, 

Or  what  not.  To  live  again  a butterfly.” 

— Christina  Rosetti. 

ANY  times  during  autumn,  the  children  find  and  bring 
in  the  very  noticeable  caterpillar  which  they  cal] 
the  “woolly  bear.”  It  seems  to  them  a companion 
of  the  road  and  the  sunshine;  it  usually  seems  in 
a hurry,  and  if  the  children  know  that  it  is  thus 
_ hastening  to  secure  some  safe  place  in  which  to 
|f/  hide  during  the  season  of  cold  and  snow,  they  are 
far  more  interested  in  its  future  fate.  If  the  cater- 
pillar is  already  curled  up  for  the  winter,  it  will 
“come  to”  if  warmed  in  the  hand  or  in  the  sunshine! 
The  woolly  bear  is  variable  in  appearance; 
sometimes  there  are  five  of  the  front  segments 
black,  four  of  the  middle  reddish  brown,  and 
three  of  the  hind  segments  black.  In  others 
there  are  only  four  front  segments  black,  six 
reddish  ones,  and  two  that  are  black  at  the  end 
of  the  body;  there  are  still  other  variations,  so  that  each  individual  will 
tell  its  own  story  of  color.  There  are  really  thirteen  segments  in  this 
caterpillar,  not  counting  the  head;  but  the  last  two  are  so  joined  that 
probably  the  children  will  only  count  twelve.  There  are  a regular  num- 
ber of  tubercles  on  each  side  of  each  segment,  and  from  each  of  these  arises 
a little  rosette  of  hairs;  but  the  tubercles  are  packed  so  closely  together, 
that  it  is  difficult  for  the  children  to  see  how  many  rosettes  there  are  on 
each  side.  While  the  body  of  the  caterpillar  looks  as  if  it  were  covered 
with  evenly  clipped  fur,  there  are  usually  a few  longer  hairs  on  the  rear 
segment. 

There  is  a pair  of  true  legs  on  each  of  the  three  front  segments  which 
form  the  thorax,  and  there  are  four  pairs  of  prolegs.  All  of  the  segments 
behind  the  front  three,  belong  to  the  abdomen,  and  the  prolegs  are  on 
the  3d,  4th,  5th  and  6th  abdominal  segments;  the  prop-leg  is  at  the  rear 
end  of  the  body.  The  true  legs  of  this  caterpillar  have  little  claws,  and 
are  as  shining  as  if  encased  in  patent  leather;  but  the  prolegs  and  prop- 
leg  are  merely  prolongations  of  the  sides  of  the  body  to  assist  the  insect  in 
holding  to  the  leaf.  The  yellow  spot  on  either  side  of  the  first  segment  is 
a spiracle ; this  is  an  opening  leading  into  the  air  tubes  within  the  body, 
around  which  the  blood  flows  and  is  thus  purified.  There  are  no  spiracles 
on  the  second  and  third  segments  of  the  thorax,  but  eight  of  the  abdominal 
segments  have  a spiracle  on  either  side. 

The  woolly  bear’s  head  is  polished  black;  its  antennas  are  two  tiny, 
yellow  projections  which  can  easily  be  seen  with  the  naked  eye.  The 
eyes  are  too  small  to  be  thus  seen;  because  of  its  minute  eyes,  the  woolly 
bear  cannot  see  very  far  and,  therefore,  it  is  obliged  to  feel  its  way.  It 
does  this  by  stretching  out  the  front  end  of  the  body  and  reaching  in  every

direction,  to  observe  if  there  is  anything  to  cling  to  in  its  neighborhood. 
When  we  try  to  seize  the  woolly  bear,  it  rolls  up  in  a little  ball,  and  the 
hairs  are  so  elastic  that  we  take  it  up  with  great  difficulty.  These  hairs 
are  a protection  from  the  attacks  of  birds  which  do  not  like  bristles  for 
food;  and  when  the  caterpillar  is  safely  rolled  up,  the  bird  sees  only  a 
little  bundle  of  bristles  and  lets  it  alone.  The  woolly  bear  feeds  upon 
many  plants,  grass,  clover,  dandelion  and  others.  It  does  not  eat  very 
much  after  we  find  it  in  autumn,  because  its  growth  is  completed.  The 
woolly  bear  should  be  kept  in  a box  which'  should  be  placed  out  of  doors, 
so  that  it  may  be  protected  from  storms  but  have  the  ordinary  winter 
temperature.  Keeping  it  in  a warm  room  during  the* winter  often  proves 
fatal. 

Normally,  the  woolly  bear  does  not  make  its  cocoon  until  April  or 
May.  It  finds  some  secluded  spot  in  the  fall,  and  there  curls  up  in 
safety  for  the  long  winter  nap;  when  the  warm  weather  comes  in  the 
spring,  it  makes  its  cocoon  by  spinning  silk  about  itself;  in  this  silk  are 
woven  the  hairs  which  it  sheds  easily  at  that  time,  and  the  whole  cocoon 
seems  made  of  felt.  It  seems  amazing  that  such  a large 
caterpillar  can  spin  about  itself  and  squeeze  itself  into 
such  a small  cocoon;  and  it  is  quite  as  amazing  to  see 
the  smooth  little  pupa  within  the  cocoon,  in  which  is 
condensed  all  that  was  essential  of  the  caterpillar. 
Sometimes  when  the  caterpillars  are  kept  in  a warm 
room,  they  make  their  cocoons  in  the  fall,  but  this  is  not 
natural. 

The  issuing  of  the  moth  from  the  cocoon  is  an 
interesting  lesson  for  the  last  of  May.  The  size  of  the 
moth  which  comes  from  the  cocoon  is  quite  comparable 
as  a miracle  with  the  size  of  the  caterpillar  that  went 
into  it.  The  moth  is  in  color  dull,  grayish,  tawny  yel- 
low with  a few  black  dots  on  the  wings;  sometimes  the 
hind  wings  are  tinted  with  dull  orange- red.  On  the  middle  of  the 
back  of  the  moth’s  body  there  is  a row  of  six  black  dots;  and  on 
each  side  of  the  body  is  a similar  row.  The  legs  are  reddish 
above  and  tipped  with  black.  The  antennas  are  small  and  inconspicuous.

LESSON  LXXII 

The  Isabella  Tiger-Moth,  or  Woolly  Bear 

Leading  thought — When  we  see  the  woolly  bear  hurrying  along  in  the 
fall,  it  is  hunting  for  some  cozy  place  in  which  to  pass  the  winter.  It 
makes  its  cocoon  of  silk  woven  with  its  own  hair.  In  May,  it  comes  forth 
a yellowish  moth  with  black  dots  on  its  wings. 

Method — Have  the  children  bring  in  woolly  bears  as  they  find  them, 
place  them  in  boxes  or  breeding  jars  which  have  grass  or  clover  growing 
in  them.  The  children  can  handle  the  caterpillars  while  they  are  study- 
ing them,  and  then  they  should  be  put  back  into  the  breeding  jars  and  be 
set  out  of  doors  where  they  can  have  natural  conditions;  thus  the  entire 
history  may  be  studied. 

The  Caterpillar 

Observations — i.  How  can  you  tell  the  woolly  bear  from  all  other 
caterpillars?  Are  tfrey  all  colored  alike?  How  many  segments  of  the 
body  are  black  at  the  front  end?  How  many  are  red?  How, many  seg- 
ments are  black  at  the  rear  end  of  the  body  ? How  many  segments  does 
this  make  in  all  ? 

2.  Look  closely  at  the  hairs  of  the  woolly  bear.  Are  they  set 
separately  or  in  rosettes?  Are  any  of  the  hairs  of  the  body  longer  than 
others  or  are  they  all  even  ? 

3.  Can  you  see,  just  back  of  the  head,  the  true  legs  with  their  little 
sharp  claws  ? How  many  are  there  ? 

4.  Can  you  see  the  fleshy  legs  along  the  sides  of  the  body?  How 
many  are  there  of  these? 


Insect  Study 


329 

5.  Can  you  see  the  prop-leg,  or  the  hindmost  leg  of  all?  Of  what  use 
to  the  caterpillar  are  these  fleshy  legs? 

6.  Describe  the  woolly  bear’s  head.  How  does  it  act  when  eating? 

7.  Can  you  see  a small,  bright  yellow  spot  on  each  side  of  the  segment 
just  behind  the  head?  What  do  you  suppose  this  is?  Can  you  see  little 
openings  along  each  side  of  all  the  segments  of  the  body,  except  the  second 
and  third?  What  are  they?  Describe  how  the  woolly  bear  breathes. 

8.  On  what  does  the  woolly  bear  feed?  If  you  can  find  a little 
woolly  bear,  give  it  fresh  grass  to  eat  and  see  how  it  grows.  Why  does  it 
shed  its  skin? 

9.  When  the  woolly  bear  is  hurrying  along,  does  it  lift  its  head  and 
the  front  end  of  its  body  now  and  then?  Why  does  it  do  this?  Do  you 
think  it  can  see  far  ? 

10.  What  does  the  woolly  bear  do  when. you  try  to  pick  it  up?  Do 
you  find  you  can  pick  it  up  easily?  Do  you  think  that  these  stiff  hairs 
protect  woolly  bear  from  its  enemies?  What  are  its  enemies? 

11.  Where  should  the  woolly  bear  be  kept  in  winter  to  make  it  com- 
fortable ? 

The  Cocoon 

1.  When  does  the  woolly  bear  make  its  cocoon? 

2.  Of  what  material  is  it  made?  How  does  the  woolly  bear  get  into 
its  cocoon? 

3.  What  happens  to  it  inside  the  cocoon? 

4.  Cut  open  a cocoon  and  describe  how  woolly  bear  looks  now. 

The  Moth 

1 . Where  did  the  moth  come  from  ? 

2.  How  did  it  come  out  of  the  cocoon?  See  if  you  can  find  the  empty 
pupa  case  in  the  cocoon. 

3.  What  is  the  color  of  the  moth  and  how  is  it  marked?  Are  the 
front  and  hind  wings  the  same  color? 

4.  What  are  the  markings  and  colors  of  the  body?  Of  the  legs  ? 

5.  What  do  you  think  that  the  Mother  Isabella  will  do,  if  you  give  her 
liberty? 


The  mute  insect,  fix' t upon  the  plant 

On  whose  soft  leaves  it  hangs,  and  from  whose  cup 

Drains  imperceptibly  its  nourishment, 

Endear'd  my  wanderings. 

— Wordsworth. 


Before  your  sight,

THE  CECROPIA 
Teacher's  Story 

E silk-worm  which  gives  us  the  silk  of  com- 
merce,-has  been  domesticated  for  centuries  in 
China.  Because  of  this  domestication,  it  is 
willing  to  be  handled  and  is  reared  successfully 
in  captivity,  and  has  thus  come  to  be  the  source 
of  most  of  our  silken  fabrics.  However,  we  have 
in  America  native  silk-worms  which  produce  a 
silk  that  is  stronger  and  makes  a more  lustrous 
cloth  than  does  that  made  from  the  Chinese 
species.  But  we  have  never  had  the  time  and 
the  patience,  here  in  America,  to  domesticate 
these  giant  silk-worms  of  ours,  and  so  they  are,  as  yet,  of  no  commercial 
importance. 

The  names  of  our  common  native  silk- worms  are:  The  cecropia, 
promethea,  polyphemus,  and  luna.  In  all  of  these  species  the  moths  are 
large  and  beautiful,  attracting  the  attention  of  everyone  who  sees  them. 
The  caterpillars  are  rarely  found,  since  their  varied  green  colors  render 
them  inconspicuous  among  leaves  on  which  they  feed.  None  of  the 
caterpillars  of  the  giant  silk-worms  occur  in  sufficient  numbers  to  injure 
the  foliage  of  our  trees  to  any  extent;  they  simply  help  nature  to  do  a 
little  needful  pruning.  All  of  the  moths  are  night  flyers  and  are,  there- 
fore, seldom  seen  except  by  those  who  are  interested  in  the  visitors  to  our 
street  lights. 

The  cecropia  is  the  largest  of  our  giant  silk-worms,  the  wings  of  the 
moth  expanding  sometimes  six  and  one-half  inches.  It  occurs  from  the 
Atlantic  Coast  to  the  Rocky  Mountains. 


Insect  Study

The  cecropia  cocoon  is  found  most  abundantly  on  our  orchard  and 
shade  trees;  it  is  called  by  the  children  the  “cradle  cocoon,”  since  it  is 
shaped  like  a hammock  and  hung  close  below  a branch,  and  it  is  a very 
safe  shelter  for  the  helpless  creature  within  it. 
It  is  made  of  two  walls  of  silk,  the  outer  one  being 
thick  and  paperlike  and  the  inner  one  thin  and 
firm;  between  these  walls  is  a matting  of  loose 
silk,  showing  that  the  insect  knows  how  to 
make  a home  that  will  protect  it  from  winter 
weather.  It  is  a clever  builder  in  another 
respect,  since  at  one  end  of  the  cocoon  it  spins 
the  silk  lengthwise  instead  of  crosswise,  thus 
making  a valve  through  which  the  moth  can 
push,  when  it  issues  in  the  spring.  It  is  very 
interesting  to  watch  one  of  these  caterpillars 
spin  its  cocoon.  It  first  makes  a framework  by 
stretching  a few  strands  of  silk,  which  it  spins 
from  a gland  opening  in  the  lower  lip;  it  then 
makes  a loose  net-work  upon  the  supporting

strands,  and  then  begins  laying 
on  the  silk  by  moving  its  head 
back  and  forth,  leaving  the  sticky 
thread  in  the  &hape  of  connect- 
ing M’s  or  of  figure  8’s.  Very 
industriously  does  it  work,  and 
after  a short  time  it  is  so  screened 
by  the  silk,  that  the  rest  of 
its  performance  remains  to  us 
a mystery.  It  is  especially 
mysterious,  since  the  inner  wall 
of  the  cocoon  encloses  so  small  a cell  that  the  caterpillar  is  obliged 
to  compress  itself  in  order  to  fit  within  it.  This  achievement 
would  be  something  like  that  of  a man  who  should  build  around

himself  a box  only  a few  inches  longer,  wider  and  thicker  than  himself. 
After  the  cocoon  is  entirely  finished,  the  caterpillar  sheds  its  skin  for 
the  last  time  and  changes  into  a pupa. 

Very  different,  indeed,  does  the  pupa  look  from  the  brilliant  colored, 
warty  caterpillar.  It  is  compact,  brown,  oval  and  smooth,  with  ability 
to  move  but  very  little  when  disturbed.  The  cases  which  contain  the 
wings,  which  are  later  to  be  the  objects  of  our  admiration,  are  now  folded 
down  like  a tight  cape  around  the  body;  and  the  antennae,  like  great 
feathers,  are  outlined  just  in  front  of  the  wing  cases.  There  is  nothing 
more  wonderful  in  all  nature  than  the  changes  which  are  worked  within 
one  of  these  little,  brown  pupa  cases;  for  within  it,  processes  go  on  which 
change  the  creature  from  a crawler  among  the  leaves  to  a winged  inhabi- 
tant of  the  air. 
When  we  see  how 
helpless  this  pupa 
is,  we  can  under- 
stand better  how 
much  the  strong 
silken  cocoon  is 
needed  for  protec- 
tion from  ene- 
mies j as  well  as 
from  inclement 
weather. 

In  spring, 
usually  in  May, 
after  the  leaves 
are  well  out  on 
the  trees,  the 
pupa  skin  is  shed 
in  its  turn,  and 
Cecropia  caterpillar  weaving  its  cocoon.  out  of  it  comes 

Photo  by  M.  V.  Slingerland.  the  Wet  and 

wrinkled  moth,  its  wings  all  crumpled,  its  furry,  soft  body  very 
untidy;  but  it  is  only  because  of  this  soft  and  crumpled  state  that  it 
is  able  to  push  its  way  out  through  the  narrow  door  into  the  outer 
world.  It  has,  on  each  side  of  its  body  just  back  of  the  head,  two 
little  horny  hooks  that  help  it  to  work  its  way  out.  It  is  certainly  a 
sorry  object  as  it  issues,  looking  as  if  it  had  been  dipped  in  water  and 
had  been  squeezed  in  an  inconsiderate  hand.  But  the  wet  wings  soon 
spread,  the  bright  antennas  stretch  out,  the  furry  body  becomes 
dry  and  fluffy,  and  the  large  moth  appears  in  all  its  perfection.  The 
ground  color  of  the  wings  is  a dusky,  grayish  brown  while  the  outer 
margins  are  clay  colored;  the  wings  are  crossed,  beyond  the  middle, 
by  a white  band  which  has  a broad  outside  margin  of  red.  There 
is  a red  spot  near  the  apex  of  the  front  wing,  just  outside  of  the 
zigzag  white  line;  each  wing  bears,  near  its  center,  a crescent-shaped 
white  spot  bordered  with  red.  But  though  it  is  so  large,  it  does 
not  need  to  eat;  the  caterpillar  did  all  the  eating  that  was  necessary 
for  the  whole  life  of  the  insect;  the  mouth  of  the  moth  is  not 
sufficiently  perfected  to  take  food. 

When  the  cecropia  caterpillar  hatches  from  the  egg,  it  is  about  a 
quarter  of  an  inch  long  and  is  black;  each  segment  is  ornamented 


Insect  Study 


333 


with  six  spiny  tubercles.  Like  all  other  caterpillars,  it  has  to  grow  by 
shedding  its  horny,  skeleton  skin,  the  soft  skin  beneath  stretching  to  give 
more  room  at  first,  then  finally  hardening  and  being  shed  in  its  turn. 
This  first  molt  of  the  cecropia  caterpillar  occurs  about  four  days  after  it 
is  hatched,  and  the  caterpillar  which  issues  looks  quite  different  than 

it  did  before;  it  is  now  dull  orange  or 
yellow  with  black  tubercles.  After  six 
or  seven  days  more  of  feeding,  the  skin  is 
again  shed  and  now  the  caterpillar  appears 
with  a yellow  body;  the  two  tubercles 
on  the  top  of  each  segment  are  now 
larger  and  more  noticeable.  They  are 
blue  on  the  first  segment,  large  and 
orange-red  on  the  second  and  third  seg- 
ments, and  greenish  blue  with  blackish 
spots  and  spines  on  all  the  other 
segments  except  the  eleventh, 
which  has  bn  top,  instead  of  a 
pair  of  tubercles,  one  large, 
yellow  tubercle,  ringed  with 
black.  The  tubercles  along  the 
side  of  the  insect  are  blue  during 
this  stage.  The  next  molt  occurs 
five  or  six  days  later;  this  time 
the  caterpillar  is  bluish  green  in 
color,  the  large  tubercles  on  the 
second  and  third  segments  being 
deep  orange,  those  on  the  upper 
part  of  the  other  segments  yel- 
low, except  those  on  the  first 
and  last  segments,  which  are  blue.  All  the  other  tubercles  along 
the  sides  are  blue.  After  the  fourth  molt  it  appears  as  an  enormous 
caterpillar,  often  attaining  the  length  . of  three  inches,  and  is  as 

large  through  as  a man’s  thumb;  its  colors 
are  the  same  as  in  the  preceding  stage. 
There  is  some  variation  in  the  colors  of  the 
tubercles  on  the  caterpillars  during  these 
different  molts;  in  the  third 
stage,  it  has  been  observed  that

the  tubercles  usually  blue  are  sometimes  black.  After  the  last  molt 
the  caterpillar  eats  voraciously  for  perhaps  two  weeks  or  longer  and 
then  begins  to  spin  its  cocoon.

LESSON  LXXII 

The  Cecropia 

Leading  thought — The  cecropia  moth  passes  the  winter  as  a pupa  in  a 
cocoon  which  the  caterpillar  builds  out  of  silk  for  the  purpose.  In  the 
spring  the  moth  issues  and  lays  her  eggs  on  some  tree,  the  leaves  of  which 
the  caterpillar  relishes.  The  caterpillars  are  large  and  green  with  beauti- 
ful blue  and  orange  tubercles. 

Method — It  is  best  to  begin  with  the  cocoons,  for  these  are  easily  found 
after  the  leaves  have  fallen.  These  cocoons  if  kept  in  the  schoolroom 
should  be  thoroughly  wet  at  least  once  a week.  However,  it  is  better  to 
keep  them  in  a box  out  of  doors  where  they  can  have  the  advantage  of 
natural  moisture  and  temperature;  and  from  those  that  are  kept  outside 
the  moths  will  not  issue,  until  the  leaves  open  upon  the  trees  and 
provide  food  for  the  young  caterpillars  when  the  eggs  hatch. 

The  Cocoon 

Observations — i.  How  does  the  cocoon  look  on  the  outside?  What  is 
its  general  shape?  To  what  is  it  fastened?  Is  it  fastened  to  the  lower 
or  the  upper  side  of  a twig?  Are  there  any  dried  leaves  attached  to  it? 

2.  Where  do  you  find  cecropia  cocoons?  How  do  they  look  on  the 
tree?  Are  they  conspicuous? 

3.  Cut  open  the  cocoon,  being  careful  not  to  hurt  the  inmate.  Can 
you  see  that  it  has  an  outer  wall  which  is  firm?  What  lies  next  to  this? 


Insect  Study 


335 


Describe  the  wall  next  to  the  pupa.  How  does  this  structure  protect  the 
pupa  from  changes  of  temperature  and  dampness? 

4.  Is  the  outside  covering  easy  to  tear?  What  birds  are  strong 
enough  to  tear  this  cocoon  apart? 

5.  Are  both  ends  of  the  cocoon  alike?  Do  you  find  one  end  where 
the  silk  is  not  woven  across  but  is  placed  lengthwise?  Why  is  this  so? 
Do  you  think  that  the  moth  can  push  out  at  this  end  better  than  at  the 
other?  Do  you  think  the  caterpillar,  when  it  wove  the  cocoon,  made  it 
this  way  so  that  the  moth  could  get  out  easily? 

The  Pupa 

1 . Take  a pupa  out  of  a cbcoon  carefully  and  place  it  on  cotton  in  a 
wide-mouthed  fruit  jar  where  it  may  be  observed.  Can  the  pupa  move 
at  all?  Is  it  unable  to  defend  itself?  Why  does  it  not  need  to  defend 
itself? 

2.  Can  you  see  in  the  pupa  the  parts  that  will  be  the  antennae  and  the 
mouth  ? 

3.  Describe  how  the  wing  coverings  look.  Count  the  rings  in  the 
abdomen. 

4.  Why  does  the  pupa  need  to  be  protected  by  a cocoon? 

The  Moth 

1 . What  is  the  first  sign  which  you  discover  that  the  moth  is  coming 
out  of  the  cocoon  ? Can  you  hear  the  little  scratching  noise  ? What  do 
you  suppose  makes  it?  How  does  the  moth  look  when  it  first  comes  out? 
If  it  were  not  all  soft  and  wet  how  could  it  come  out  from  so  small  an 
opening? 

2 . Describe  how  the  crumpled  wings  spread  out  and  dry.  How  does 
the  covering  of  the  wings  change  in  looks  ? 

3 . Make  a water-color  drawing  or  describe  in  detail  the  fully  expanded 
moth,  showing  the  color  and  markings  of  wings,  body  and  antennae. 

4.  Do  the  moths  eat  anything?  Why  do  they  not  need  to  eat? 

5.  If  one  of  the  moths  lays  eggs,  describe  the  eggs,  noting  color,  size 
and  the  way  they  are  placed. 

The  Caterpillar 

1.  On  what  do  you  find  the  cecropia  caterpillar  feeding?  Describe 
its  actions  while  feeding. 

2.  What  is  the  color  of  the  caterpillar?  Describe  how  it  is  orna- 
mented. 

3 . Can  you  see  the  breathing  pores,  or  spiracles,  along  the  sides  of  the 
body?  How  many  of  these  bn  each  segment?  How  do  they  help  the 
caterpillar  to  breathe  ? 

4.  Describe  the  three  pairs  of  true  legs  on  the  three  segments  just 
back  of  the  head.  Do  these  differ  in  form  from  the  prolegs  along  the  sides 
of  the  body?  What  is  the  special  use  of  the  prolegs?  Describe  the  prop- 
leg  which  is  the  hindmost  leg  of  all. 

5.  Do  you  know  how  many  times  the  cecropia  caterpillar  sheds  its 
skin  while  it  is  growing?  Is  it  always  the  same  color? 

6.  Watch  the  caterpillar  spin  its  cocoon,  describe  how  it  begins  and 
how  it  acts  as  long  as  you  can  see  it.  Where  does  the  silk  come  from?

THE  PROMETHEA 
Teacher's  Story 

HE  promethea  is  not  so  large  as  the  cecropia, 
although  the  female  resembles  the  latter  some- 
what. It  is  the  most  common  of  all  our  giant 
silk- worms.  Its  caterpillars  feed  upon  wild 
cherry,  lilac,  ash,  sassafras,  buttonwood  and 
many  other  forest  trees. 

During  the  winter,  leaves  may  often  be  seen 
hanging  straight  down  from  the  branches  of 
wild  cherry,  lilac  and  ash.  If  these  leaves  are 
examined,  they  will  be  found  to  be  wrapped 
around  a silken  case  containing  the  pupa  of  the 
promethea.  It  is  certainly  a canny  insect 
which  hides  itself  during  the  winter  in  so  good 
a disguise,  that  only  the  very  wisest  of  birds 
ever  suspect  its  presence.  When  the  promethea  caterpillar  begins  to 
spin,  it  selects  a leaf  and  covers  the  upper  side  with  silk,  then  it  covers  the 
petiole  with  silk,  fastening  it  with  a strong  band  to  the  twig,  so  that  not 
even  most  violent  winter  winds  will  be  able  to  tear  it  off.  Then  it  draws 
the  two  edges  of  the  leaf  about  itself  like  a cloak  as  far  as  it  will  reach,  and 
inside  this  folded  leaf  it  makes  its  cocoon,  which  always  has  an  opening  in 
the  shape  of  a conical  valve  at  the  upper  end,  through  which  the  moth

may  . .emerge  in  the  spring.  This  caterpillar  knows  more  botany  than 
some  people  do,  for  it  makes  no  mistake  in  distinguishing  a compound 
leaf  from  a simple  one.  When  it  uses  a leaflet  of  hickory  for  its  cocoon, 
it  fastens  the  leaflet  to  the  mid  stem  of  the  leaf  and  then  fastens  the  stem 
to  the  twig.  The  male  pupa  is  much  more  slender  than  that  of  the  female. 
The  moths  do  not  issue  until  May  or  June. 

The  moth  works  its  way  out  through  the  valve  at  the  top  of  the  cocoon. 
The  female  is  a large,  reddish  brown  moth  with  markings  resembling 
somewhat  those  of  the  cecropia.  The  male  is  very  different  in  appear- 
ance; its  front  wings  have  very  graceful,  prolonged  tips,  and  both  wings 
are  almost  black,  bordered  with  ash  color.  The  promethea  moths  differ 
somewhat  in  habit  from  the  other  silk-worms,  in  that  they  fly  during  the 
late  afternoon  as  well  as  at  night.  The  eggs  are  whitish  with  brown  stain, 
and  are  laid  in  rows,  a good  many  on  the  same  leaf. 

The  caterpillars,  as  they  hatch  from  the  eggs,  have  bodies  ringed  with 
black  and  yellow.  They  are  sociable  little  fellows  and  live  together  side 
by  side  amicably,  not  exactly  “toeing  the  mark’’  like  a spelling  class,  but 
all  heads  in  a row  at  the  edge  of  the  leaf  where  each  js  eating  as  fast  as 

possible.  When  they 
are  small,  the  caterpil- 
lars remain  on  the  under 
side  of  the  leaves  out  of 
sight.  In  about  five 
days,  the  first  skin  is 
shed  and  the  color  of  the 
caterpillar  remains  about 
the  same.  Four  or  five 
days  later,  the  second 
molt  occurs,  and  then 
the  caterpillar  appears  in 
a beautiful  bluish  green 
costume,  with  black 
tubercles,  except  four 
large  ones  on  the  second 
and  third  segments,  and 
one  large  one  on  the 
eleventh  segment,  which 
are  yellow.  This  cater- 
pillar has  an  interesting 
habit  of  weaving  a carpet  of  silk  on  which  to  change  its  skin ; it  seems 
to  be  better  able  to  hold  on  while  pushing  off  the  old  skin,  if  it  has  the 
silken  rug  to  cling  to.  After  the  third  molt,  the  color  is  a deeper  greenish 
blue  and  the  black  tubercles  are  smaller,  and  the  five  big  ones  are  larger 
and  bright  orange  in  color.  After  the  fourth  molt,  which  occurs  after  a 
period  of  about  five  or  six  days,  the  caterpillar  appears  in  its  last  stage. 
It  is  now  over  two  inches  long,  quite  smooth  and  most  prosperous  looking. 
Its  color  is  a beautiful,  light,  greenish  blue,  and  its  head  is  yellow.  It  has 
six  rows  of  short,  round,  black  tubercles.  The  four  large  tubercles  at  the 
front  end  of  the  body  are  red,  and  the  large  tubercle  on  the  rear  end  of  the 
body  is  yellow. 

The  cynthia  is  a beautiful  moth  which  has  come  to  us  from  Asia ; it  is 
very  large  with  a ground  color  of  olive-green,  with  lavender  tints  and

white  markings;  there  are  white  tufts  of  hairs  on  the  abdomen.  It 
builds  its  cocoon  like  the  promethea,  fastening  the  petiole  to  the  twig.

therefore  the  lesson  indicated  for  the  promethea  will  serve  as  well  foi 
the  cynthia.  The  cynthia  caterpillars  live  upon  the  ailanthus  tree  and 
are  found  only  in  the  regions  where  this  tree  has  been  introduced.

LESSON  LXXIV 

The  Promethea 

Leading  thought — The  promethea  caterpillar  fastens  a leaf  to  a twig 
with  silk  and  then  makes  its  cocoon  within  this  leaf.  The  male  and  female 
moths  are  very  different  in  appearance. 

Method — This  work  should  begin  in  the  late  fall,  when  the  children 
bring  in  these  cocoons  which  they  find  dangling  on  the  lilac  bushes  or 
wild  cherry  trees.  Much  attention  should  be  paid  to  the  way  the  leaf  is 
fastened  to  the  twig  so  it  will  not  fall.  The  cocoons  should  be  kept  out 
of  doors,  so  that  the  moths  will  issue  late  in  the  spring  when  they  can  have 
natural  conditions  for  laying  their  eggs,  and  the  young  caterpillars  are 
upplied  with  plenty  of  food  consisting  of  new  and  tender  leaves. 

The  Cocoon 

Observations — i On  what  tree  did  you  find  it?  Does  it  look  like  a 

cocoon  ? Does  it  not  look  like  a dried  leaf  still  clinging  to  the  tree  ? Do 
you  think  that  this  disguise  keeps  the  birds  from  attacking  it?  Do  you 
know  which  birds  are  clever  enough  to  see  through  this  disguise  ? 

2.  How  is  the  leaf  fastened  to  the  twig?  Could  you  pull  it  off  readily? 
What  fastened  the  leaf  to  the  twig? 

3.  Tear  off  the  leaf  and  study  the  cocoon.  Is  there  an  opening  to  it? 
At  which  end?  What  is  this  for? 

4.  Cut  open  a cocoon.  Is  it  as  thick  as  that  of  the  cecropia ? 

5.  Study  the  pupa.  Is  it  as  large  as  that  of  the  cecropia? 

6.  Can  you  see  where  the  antennae  of  the  moth  are?  Can  you  see  the 
wing  covers?  Can  the  pupa  move? 

The  Moth 

1.  Are  there  two  kinds  of  moths  that  come  from  the  promethea 
cocoons  ? Does  one  of  them  look  something  like  the  cecropia  ? This  is 
the  mother  promethea. 

2.  Are  any  of  the  moths  almost  black  in  color  with  wings  bordered 
with  gray  and  with  graceful  prolonged  tips  to  the  front  wings?  This  is 
the  father  moth. 

3 . Make  water  color  drawings  of  promethea  moths,  male  and  female. 

4.  If  a promethea  mother  lays  eggs,  describe  them. 

The  Caterpillar 

1.  How  do  the  promethea  caterpillars  look  when  they  first  hatch 
from  the  eggs ? Do  they  stay  together  when  they  are  very  young?  How 
do  they  act?  Where  do  they  hide? 

2.  How  do  they  change  color  as  they  grow  older?  Do  they  remain 
together  or  scatter?  Do  they  continue  to  hide  on  the  lower  sides  of 
leaves  ? 

3 . . What  preparation  does  a promethea  caterpillar  make  before 
changing  its  skin?  Why  does  it  shed  its  skin?  Does  its  colors  change 
with  every  change  of  skin? 

4.  Describe  the  caterpillar  when  it  is  full-grown.  What  is  its 
ground  color?  What  are  the  colors  of  its  ornamental  tubercles?  The 
color  of  its  head? 

5.  Describe  how  a promethea  caterpillar  makes  its  cocoon.

THE  HUMMINGBIRD,  OR  SPHINX,  MOTHS 
Teacher's  Story 

F during  the  early  evening,  when  all  the  swift  hum- 
ming birds  are  abed,  we  hear  the  whirr  of  rapidly 
moving  wings  and  detect  the  blur  of  them  in  the 
twilight,  as  if  the  creature  carried  by  them  hung 
entranced  before  some  deep-throated  flower,  and 
then  whizzed  away  like  a bullet,  we  know  that  it 
was  a hummingbird,  or  sphinx,  moth.  And  when 
we  see  a caterpillar  with  a horn  on  the  wrong  end  of 
the  body,  a caterpillar  which,  when  disturbed,  rears 
threateningly,  then  we  may  know  it  is  the  sphinx 
larva.  And  when  we  find  a strange,  brown  seg- 
mented shell,  with  a long  jug  handle  at  one  side,  buried  in  the  earth  as 
we  spade  up  the  garden  in  the  spring,  then  we  know  we  have  the  sphinx 
pupa. 

The  sphinx  was  a vaudeville  person  of  ancient  mythology  who  went 
about  boring  people  by  asking  them  riddles;  and,  if  they  could  not  give 
the  right  answers,  very  promptly  ate  them  up.  Although  Linnaeus  gave 
the  name  of  sphinx  to  these  moths,  because  he  fancied  he  saw  a resem- 
blance in  the  resting  or  threatening  attitude  of  the  larvae  to  the  Egyptian 
Sphinx,  there  are  still  other  resemblances.  These  insects  present  three 
riddles:  The  first  one  is,  “Am  I a humming-bird?”  the  second,  “Why  do 
I wear  a horn  or  an  eye-spot  on  the  rear  end  of  my  body  where  horns 
and  eyes  are  surely  useless?”  and  the  third,  “Why  do  I look  like  a jug 
with  a handle  and  no  spout?” 

The  sphinx  moths  are  beautiful  and  elegant  creatures.  They  have 
a distinctly  tailor-made  appearance,  their  colors  are  so  genteel  and 
“the  cut”  so  perfect.  They  have  long,  rather  narrow,  strong  wings 
which  enable  them  to  fly  with  extra- 
ordinary rapidity.  The  hind  wings 
are  shorter,  but  act  as  one  with  the 
front  wings.  The  body  is  stout  and 
spindle-shaped.  The  antennae  are 
thickened  in  the  middle  or  toward 
the  tip,  and  in  many  species  have 
the  tip  recurved  into  a hook. 

Their  colors  show  most  harmonious 
combinations  and  most  exquisite 
contrasts;  the  pattern,  although 
often  complex,  shows  perfect  re- 
finement. Olive,  tan,  brown  and 
ochre,  black  and  yellow,  and  the 
whole  gamut  of  greys,  with  eye- 
spots  or  bands  athwart 
the  hind  wings  of  rose 
color  or  crimson  t are 
some  of  the  sphinx  color 
schemes. 

Most  of  the  sphinx 
moths  have 


Insect  Study 


34i 


able  long  tongues,  being  sometimes 
twice  the  length  of  the  body. 
When  not  in  use,  the  tongue  is  curled 
like  a watch  spring  in  front  and  beneath 
the  head;  but  of  what  possible  use  is 
such  a long  tongue ! That  is  a story  for 
certain  flowers  to  tell,  the  flowers  which 
have  the  nectar  wells  far  down  at  the 
base  of  tubular  corollas,  like  the  petunia, 
the  morning  glory  or  the  nasturtium; 
such  flowers  were  evidently  developed  to 
match  the  long-tongued  insects.  Some 
of  these  flowers,  like  the  jimson  weed  and 
nicotina,  open  late  in  the  day  so  as  to  be 
ready  for  these  evening  visitors.  In 
some  cases,  especially  in  the  orchids, 
there  is  a special  partnership  established 
between  one  species  of  flower  and  one 
species  of  sphinx  moths.  The  tobacco 
sphinx  is  an  instance  of  such  partner- 
ship ; this  moth  visits  tobacco  flowers  and  helps  develop  the  seeds 
by  carrying  pollen  from  flower  to  flower;  and  in  turn  it  lays  its 
eggs  upon  the  leaves 
of  this  plant,  on  which 
its  great  caterpillar 
feeds  and  waxes  fat, 
and  in  high  dudgeon 
often  disputes  the 
smoker’s  sole  right  to 
the  “weed.”  Tobacco 
probably  receives 
enough  benefit  from 
the  ministrations  of 
the  moth  to  compen- 
sate for  the  injury  it 
suffers  from  the  cater- 
pillars ; but  the  owner 
of  the  tobacco  field, 
not  being  a plant,  does 
not  look  at  it  in  this  equitable  manner. 

The  sphinx  caterpillars  are  leaf  eaters  and  each  species  feeds  upon  a 
limited  number  of  plants  which  are  usually  related;  for  instance,  one 
feeds  upon  both  the  potato  and  tomato;  another  upon  the  Virginia 
creeper  and  grapes.  In  color  these  caterpillars  so  resemble  the  leaves 
that  they  are  discovered  with  difficulty.  Those  on  the  Virginia  creeper, 
which,  shades  porches,  may  be  located  by  the  black  pellets  of  waste 
material  which  fall  from  them  to  the  ground ; but  even  after  this  unmis- 
takable hint  I have  searched  a long  time  to  find  the  caterpillar  in  the 
leaves  above;  its  color  serves  to  hide  the  insect  from  birds  which  feed 
upon  it  eagerly.  In  some  species,  the  caterpillars  are  ornamented  with 
oblique  stripes  along  the  sides,  and  in  others  the  stripes  are  lengthwise. 
There  is  often  a great  variation  in  color  between  the  % caterpillars  of

the  same  species;  the  tomato  worm 
is  sometimes  green  and  sometimes 
black. 

The  horn  on  the  rear  end  is  often 
in  the  young  larva  of  different  color 
than  the  body;  in  some  species  it 
stands  straight  up  and  in  some  it  is 
curled  toward  the  back.  It  is  an 
absolutely  harmless  projection  and 
does  not  sting  nor  is  it  poison- 
ous. However,  it  looks  awe-inspiring  and  perhaps  protects  its  owner  m 
that  way.  The  Pandora  sphinx  has  its  horn  curled  over  its  back  in  the 
young  stage  but  when  fully  grown  the  horn  is  shed ; in  its  place  is  an  eye- 
spot  which,  if  seen  between  the  leaves,  is  enough  to  frighten  away  any 
cautious  bird  fearing  the  evil  eye  of  serpents.  The  sphinx  caterpillars 
have  a habit,  when  disturbed  or  when  resting,  of  rearing  up  the  front  part 
of  the  body,  telescoping  the  head  back  into  the  thoracic  segments,  which  in 
most  species  are  enlarged,  and  assuming  a most  threatening  and  ferocious 
aspect.  If  attacked  they  will  swing  sidewise,  this  way  and  then  that, 
making  a fierce  crackling  sound  meanwhile,  well  calculated  to  fill  the 
trespasser  with  terror.  When  resting  they  often  remain  in  this  lifted 

attitude  for  hours,  ab- 
solutely rigid. 

The  six  true  legs  are 
short  with  sharp,  little 
claws.  There  are  four 
pairs  of  fleshy  prolegs, 
each  foot  being  armed 
with  hooks  for  holding  on 
to  leaf  or  twig;  and  the 
large,  fleshy  prop-leg  on 
the  rear  segment  is  able  to 
clasp  a twig  like  a vise. 
All  these  fleshy  legs  are 
used  for  holding  on,  while  the  true  legs  are  used  for  holding  the  edges 
of  the  leaf  where  the  sidewise  working  jaws  can  cut  it  freely.  These 
caterpillars  do  clean  work,  leaving  only  the  harder  and  more  woody 
ribs  of  the  leaves.  The  myron  caterpillar  seems 
to  go  out  of  its  way  to  cut  off  the  stems  of 
both  the  grape  and  Virginia  creeper. 

There  are  nine  pairs  of  spiracles,  a pair  on 
each  segment  of  the  abdomen  and  on  the  first 
thoracic  segment.  The  edges  of  these  air 
openings  are  often  strikingly  colored.  Through 
the  spiracles  the  air  is  admitted  into 
all  the  breathing  tubes  of  the  body  around 
which  the  blood  flows  and  is  purified ; no  insect 
breathes  through  its  mouth.  These  cater- 
pillars, like  all  others,  grow  by  shedding  the 
skeleton  skin,  which  splits  down  the  back. 

Often  one  of  these  caterpillars  is  seen 
covered  with  white  objects  which  the  ignorant,

who  do  not  know  that  caterpillars  never  lay  eggs,  have  called,  eggs. 
But  the  sphinx  moths  at  any  stage  would  have  horror  of  such  eggs  as 
these!  They  are  not  eggs  but  are  little  silken  cocoons  spun  by  the 
larvae  of  a hymenopterous  parasite.  It  is  a tiny,  four-winged  “fly”  which 
lays  its  eggs  within  the  caterpillar.  The  little  grubs  which  hatch  from 
these  eggs  feed  upon  the  fleshy  portions  of  the  caterpillar  until  they  get 
their  growth,  at  which  time  the  poor  caterpillar  is  almost  exhausted; 
and  then  they  have  the  impudence  to  come  out  and  spin  their 

silken  cocoons  and 
fasten  them  to  the 
back  of  their  victim. 
Later,  they  cut  a little 
lid  to  their  silken  cells 
which  they  lift  up  as 
they  come  out  into 
the  world  to  search 
for  more  caterpillars. 

As  soon  as  the 
sphinx  larva  has  ob- 
tained its  growth,  it 
descends  and  burrows 
into  the  earth.  It

cocoon  but  packs  the 

soil  into  a smooth -walled  cell  in  which  it  changes  to  a pupa.  In  the 
spring  the  pupa  works  its  way  to  the  surface  of  the  ground  and  the  moth 
issues.  In  the  case  of  the  tomato  and  tobacco  sphinx  pupa,  the  enor- 
mously long  tongue  has  its  case  separate  from  the  body  of  the  pupa,  which 
makes  the  “jug  handle.”  The  wing  cases  and  the  antennae  cases  can  be 
distinctly  seen.  In  the  case  of  the  other  species  the  pupae  have  the 
tongue  case  fast  to  the  body.  The  larva  of  the  myroti  sphinx  does  not 
enter  the  ground,  but  draws  a few  leaves  about  it  on  the  surface  of  the 
ground,  fastens  them  with  silk  and  there  changes  to  a pupa.

LESSON  LXXV 

The  Humming-bird,  or  Sphinx,  Moths 

Leading  thought — The  sphinx  caterpillars  have  a slender  horn  or  eye- 
spot.  on  the  last  segment  of  the  body.  When  disturbed  or  when  resting 
they  rear  the  front  part  of  the  body  in  a threatening  attitude.  They  spin 
no  cocoons  but  change  to  pupae  in  the  ground.  The  adults  are  called 
humming-bird  moths,  because  of  their  swift  and  purring  flight.  Many 
flowers  depend  upon  the  sphinx  moths  for  carrying  their  pollen. 

Method — The  sphinx  caterpillar  found  on  the  potato  or  tobacco,  or 
one  of  the  species  feeding  upon  the  Virginia  creeper  is  in  September 
available  in  almost  any  locality  for  this  lesson.  The  caterpillars  should 
be  placed  in  a breeding  cage  in  the  schoolroom.  Fresh  food  should  be 
given  them  every  day  and  moist  earth  be  placed  in  the  bottom  of  the 
cages.  It  is  useless  for  the  amateur  to  try  to  rear  the  adults  from  the 
pupae  in  breeding  cages.  • The  moths  may  be  caught  in  nets  during  the 
evernng  when  they  are  hovering  over  the  petunia  beds.  These  may  be

Observations — i.  On  what  plant  is  it  feeding?  Wrhat  is  its  general 
color?  Is  it  striped?  What  colors  in  the  stripes?  Are  they  oblique  or 
lengthwise  stripes?  Are  all  the  caterpillars  the  same  color?

2.  Can  you  find  the  caterpillar  easily  when  feeding?  Why  is  it  not 
conspicuous  when  on  the  plant?  Of  what  use  is  this  to  the  caterpillar? 

3.  Note  the  horn  on  the  end  of  the  caterpillar.  Is  it  straight  or 
curled?  Is  it  on  the  head  end?  What  color  is  it?  Do  you  think  it  is  of 
any  use  to  the  caterpillar?  Do  you  think  it  is  a sting?  If  there  is  no 
horn,  is  there  an  eye-spot  on  the  last  segment?  What  color  is  it?  Can 
you  think  of  any  way  in  which  this  eye-spot  protects  the  caterpillar? 

4.  Which  segments  of  the  caterpillar  are  the  largest?  When  the 
creature  is  disturbed  what  position  does  it  assume?  How  does  it  move? 
What  noise  does  it  make?  Do  you  think  this  attitude  scares  away  ene- 
mies? What  position  does  it  assume  when  resting?  Do  you  think  that 
it  resembles  the  Egyptian  Sphinx  when  resting? 

5.  How  many  true  legs  has  this  caterpillar?  How  does  it  use  them 
when  feeding?  How  many  prolegs  has  it?  How  are  these  fleshy  legs 
used?  How  are  they  armed  to  hold  fast  to  the  leaf  or  twig?  Describe 
the  hind  or  prop-leg.  How  is  it  used? 

6.  Do  you  see  the  breathing- 
pores  or  spiracles  along  the  sides 
of  the  body?  How  many  are 
there?  How  are  they  colored? 
How  does  the  caterpillar  breathe? 
Do  you  think  it  can  breathe 
through  its  mouth? 

7 . How  does  the  sphinx  cater- 
pillar grow?  Watch  your  cater- 
pillar and  see  it  shed  its  skin. 
Where  does  the  old  skin  break 
open?  How  does  the  new,  soft 
skin  look?  Do  the  young  cater- 
pillars resemble  the  full-grown 
ones? 

8.  Describe  how  the  cater- 
pillar eats.  Can  you  see  the  jaws 
move?  Does  it  eat  up  the  plant 
clean  as  it  goes? 

9.  Have  you  ever  found  the  sphinx  caterpillar  covered  with  whitish, 
oval  objects?  What  are  these?  Does  the  caterpillar  look  plump  or 
emaciated?  Explain  what  these  objects  are  and  how'  they  came  to  be 
there. 

10.  Where  does  the  caterpillar  go  to  change  to  a pupa?  Does 
it  make  cocoons?  How  does  the  pupa  look?  Can  you  see  the  long 
tongue  case,  the  wing  cases,  the  antennae  cases? 

The  Moth 

1.  Where  did  you  find  this  moth?  Was  it  flying  by  daylight  or  in 
the  dusk?  How  did  its  swift  moving  wings  sound?  Was  it  visit- 
ing flowers?  What  flowers?  Where  is  the  nectar  in  these  flowers? 

2.  What  is  the  shape  of  the  moth’s  body?  Is  it  stout  or  slender? 
What  colors  has  it?  How  is  it  marked? 

3.  The  wings  of  which  pair  are  longer?  Sketch  or  describe  the 
form  of  the  front  and  the  hind  wings?  Are  the  outer  edges  scalloped,

notched  or  even?  What 
colors  are  on  the  front  wing? 
On  the  hind  one?  Are  these 
colors  harmonious  and  beauti- 
ful? Make  a sketch  of  the 
moth  in  water-color. 

4.  What  is  the  shape  of 
the  antennae?  Describe  the 
eyes.  Can  you  see  the  coiled 
tongue?  Uncoil  it  with  a 
pin  and  note  how  long  it  is. 
Why  does  this  moth  need  such 
a long  tongue  ? 

5.  From  what  flowers  do 
the  sphinx  moths  get  nectar? 
How  does  the  moth  support 
itself  when  probing  for  nectar? 
Do  you  know  any  flowers 
which  are  dependent  on  the 
sphinx  moths  for  carrying 
their  pollen?  How  many 
kinds  of  sphinx  moths  do  you 
know?

THE  CODLING  MOTH 
Teacher's  Story 

difficult  to  decide  which  seems  the  most  disturbed, 
the  person  who  bites  into  an  apple  and  uncovers 
a worm,  or  the  worm  which  is  uncovered.  From 
our  standpoint,  there  is  nothing  attractive  about 
the  worm  which  destroys  the  beauty  and  appetizing 
qualities  of  our  fruit,  but  from  the  insect  stand- 
point the  codling  caterpillar  (which  is  not  a worm 
at  alll,  is  not  at  all  bad.  When  full-grown,  it  is 
about  three-fourths  of  an  inch  long,  and  is  likely 
to  be  flesh  color,  or  even  rose  color,  with  brownish 
head;  as  a young  larva,  it  has  a number  of 
darker  rose  spots  on  each  segment  and  is  whitish 
in  color;  the  shield  on  the  first  segment  behind  the  head,  and 
that  on  the  last  segment  of  the  body,  are  black.  When  full-grown,  the 
apple  worm  is  plump  and  lively;  and  while  jerking  angrily  at  being  dis- 
turbed, we  can  see  its  true  legs,  one  pair  to  each  of  the  three  segments  of 
the  body  behind  the  head.  These  true  legs  have  sharp,  single  claws. 
Behind  these  the  third,  fourth,  fifth  and  sixth  segments  of  the  abdomen 
are  each  furnished  with  a pair  of  fleshy  prolegs  and  the  hind  segment  has  a 
prop-leg.  These  fleshy  legs  are  mere  makeshifts  on  the  part  of  the  cater- 
pillar for  carrying  the  long  body;  since  the  three  pairs  of  front  legs  are 
the  ones  from  which  develop  the  legs  of  the  moth.  The  noticing  of  the 
legs  of  the  codling  moth  is  an  important  observation  on  the  part  of  the 
pupils,  since,  by  their  presence,  this  insect  may  be  distinguished  from 
the  young  of  the  plum  curculio,  which  is  also  found  in  apples  but  which 
is  legless.  The  codling  moth  has  twelve  segments  in  the  body,  back  of 
the  head. 

The  codling  larva  usually  enters  the  apple  at  the  blossom  end  and 
tunnels  down  by  the  side  of  the  core  until  it  reaches  the  middle,  before  • 
making  its  way  out  into  the  pulp.  The  larva  weaves  a web  as  it  goes, 
but  this  is  probably  incidental,  since  many  caterpillars  spin  silk  as  they 
go,  “street  yarn”  our  grandmothers  might  have  called  it.  In  this  web  are 
entangled  the  pellets  of  indigestible  matter,  making  a very  unsavory 
looking  mass.  The  place  of  exit  is  usually  circular,  large  enough  to 
accommodate  the  body  of  the  larva,  and  it  leads  out  from  a tunnel  which 
may  be  a half  inch  or  more  in  diameter  beneath  the  rind.  Often  the  larva 
makes  the  door  sometime  before  it  is  ready  to  leave  the  apple,  and  plugs 
it  with  a mass  of  debris,  fastened  together  with  the  silk.  As  it  leaves  the 
apple,  the  remnants  of  this  plug  may  be  seen  streaming  out  of  the  open- 
ing. Often  also,  there  is  a mass  of  waste  pellets  pushed  out  by  the  young 
larva  from  its  burrow,  as  it  enters  the  apple;  thus  it  injures  the  appear- 
ance of  the  apple,  at  both  entrance  and  exit.  If  the  apple  has  not  received 
infection  by  lying  next  to  another  rotting  apple,  it  first  begins  to  rot 
around  the  burrow  of  the  worm,  especially  near  the  place  of  exit. 

The  codling  caterpillar  injures  the  fruit  in  the  following  ways:  The 

apples  are  likely  to  be  stunted  and  fall  early;  the  apples  rot  about  the 
injured  places  and  thus  cannot  be  stored  successfullv ; the  apples  thus 
injured  look  unattractive  and,  therefore,  their  market  value  is  lessened; 
wormy  apples,  packed  in  barrels  with  others,  rot  and  contaminate  all  the

neighboring  apples.  This 
insect  also  attacks  pears 
and  sometimes  peaches.  It 
has  been  carefully  estimated 
that  every  year  "the  codling 
moth  does  three  million 
dollars  worth  of  injury  to 
the  apple  and  pear  crops  in 
New  York  State.  Think  of 
paying  three  million  dollars 
a year  for  the  sake  of  having 
wormy  apples! 

The  larvae  usually  leave 
the  apples  before  winter.  If 
the  apples  have  fallen,  they 
crawl  up  the  tree  and  there 
make  their  cocoons  beneath

are  on  the  trees,  they  spin 
silk  and  swing  down.  If  carried  into  the  storeroom  or  placed  in 
barrels,  they  seek  quarters  in  protected  crevices.  In  fact,  while  they 
particularly  like  the  loose  bark  of  the  apple  trees,  they  are  likely  to  build 
their  cocoons  on' nearby  fences  or  on  brush,  wherever  they  can  find  the 
needed  protection.  The  cocoon  is  made  of  fine  but  rather  rough  silk 
which  is  spun  from  a gland  opening  near  the  mouth  of  the  caterpillar; 
the  cocoon  is  not  beautiful  although  it  is  smooth  inside.  It  is  usually 
spun  between  a loose  bit  of  bark  and  the  body  of  the  tree;  but  after  mak- 
ing it,  the  insect  seems  in  no  hurry  to  change  its  condition  and  remains  a 
quite  lively  caterpillar  until  spring.  It  is  while  the  codling  larvae  are  in 
their  winter  quarters  that  our  bird 
friends  of  the  winter,  the  nut- 
hatches, woodpeckers  and  chicka- 
dees, destroy  them  in  great  num- 
bers, hunting  eagerly  for  them  in 
every  crevice  of  the  trees.  It  is 
therefore  good  policy  for  us  to  coax 
these  birds  to  our  orchards  by 
placing  beef  fat  on  the  branches 
and  thus  entice  these  little  cater- 
pillar hunters  to  visit  the  trees 
every  day. 

It  is  an  interesting  fact  that  the 
codling  caterpillars,  which  make 
cocoons  before  August  first,  change 
immediately  to  pupae  which  soon 
change  to  moths,  and  thus  another 
generation  gets  in  its  work  before 
the  apples  are  harvested.

and  a brown,  mottled  and  banded 
body;  its  wings  are  graced  by  wavy 
bands  of  ashy  and  brown  lines,  and  the 
tips  of  the  front  wings  are  dark  brown 
with  a pattern  of  gold  bronze  wrought 
into  them;  the  hind  wings  are  shiny 
brown  with  darker  edges  and  little 
fringes.  The  moths  issue  in  the  spring 
and  lay  their  eggs  on  the  young  apples 
just  after  the  petals  fall.  The  egg 
looks  like  a minute  drop  of  dried  milk 
and  is  laid  on  the  side  of  the  bud;  but 
the  little  larva,  soon  after  it  is  hatched, 
crawls  to  the  blossom  and  finds  entrance 
there;  and  it  is  therefore  important 
that  its  first  lunch  should  include  a bit 
of  arsenic  and  thus  end  its  career  before 
it  fairly  begins.  The  trees  should  be 
sprayed  with  some  arsenical  poison 
directly  after  the  petals  fall,  and  before 
the  five  lobes  of  the  calyx  close  up 
around  the  stamens.  If  the  trees  are 
sprayed  while  blossoming,  the  pollen 
is  washed  away  and  the  apples  do  not  The  pupae  and  cocoons  of  the

If  the  trees  are  sprayed  directly  after 

the  calyx  closes  up  around  the  stamens  the  poison  does  not  lodge 
at  the  base  of  the  stamens  and  the  little  rascals  get  into  the  apples  without 
getting  a dose.  (See  Lesson  on  the  Apple) . 


LESSON  LXXVI 
The  Codling  Moth 

Leading  thought — The  codling  moth  is  a tiny  brown  moth  with  bronze 

markings  which  lays  its 
egg  on  the  apple.  The 
larva  hatching  from  the 
egg  enters  the  blossom 
end  and  feeds  upon  the 
pulp  of  the  apple,  in- 
juring it  greatly.  After 
attaining  its  growth,  it 
leaves  the  apple  and 
hides  beneath  the  bark 
of  the  tree  or  in  other 
protected  places,  and 
in  the  spring  makes 
the  cocoon  from  which 
the  moth  issues  in  time 
to  lay  eggs  upon  the 
young  apples.

ber of  hibernating  larvae  found  in  their  winter  quarters.  Place  these 
larvae  in  a box  with  cheese-cloth  tacked  over  its  open  side;  place 
this  box  out  of  doors  in  a protected  position.  Examine  the  cocoons 
to  find  the  pupae  about  the  last  of  April;  after  the  pupae  appear,  look  for 
the  moths  in  about  five  days. 

It  would  be  a very  good  idea  for  the  pupils  to  prepare  a Riker  mount 
showing  specimens  of  the  moths,  of  the  cocoons  shewing  the  cast  pupa 
skin,  and  of  the  caterpillar  in  a homeopathic  vial  of  alcohol;  pictures 
illustrating  the  work  of  the  insect  may  be  added.  The  pictures  should 
be  drawn  by  the  pupils,  showing  the  wormy  apple,  both  the  outside  and 
in  section.  The  pupils  can  also  sketch,  from  the  pictures  here  given,  the 
young  apple  when  just  in  the  right  condition  to  spray,  with  a note  explain* 
ing  why. 

Observations — i.  Find  an  apple  with  a codling  moth  larva  in  it. 
How  large  is  the  worm?  How  does  it  act  when  disturbed? 

2.  What  is  the  color  of  the  caterpillar’s  body?  Its  head? 

3.  How  many  segments  are  there  in  the  body?  How  many  of  these 
bear  legs?  What  is  the  difference  in  form  between  the  three  front  pairs 
of  legs  and  the  others? 

4.  Look  at  a wormy  apple.  How  can  you  tell  it  is  wormy  from  the 
outside?  Can  you  see  where  the  worm  entered  the  apple?  Was  the 
burrow  large  or  small  at  first?  Can  you  find  an  apple  with  a worm  in  it 
which  has  the  door  for  exit  made,  but  closed  with  waste  matter?  How  is 
this  matter  fastened  together?  If  the  apple  has  no  worm  in  it,  can  you 
see  where  it  left  the  apple?  Make  a sketch  or  describe  the  evidence  o* 
the  caterpillar’s  progress  through  the  apple.  Do  you  find  a web  of  silk  in 


Insect  Study  351 

the  wormy  part?  Why  is  this?  Does  the  worm  eat  the  seeds  as  well  as 
the  pulp  of  the  apple? 

5.  Take  a dozen  rotting  apples,  how  many  of  them  are  wormy? 
Do  the  parts  of  the  apple  injured  by  the  worm  begin  to  rot  first?  In  how 
many  ways  does  the  codling  moth  injure  the  apple?  Does  it  injure  other 
fruits  than  apples? 

6.  How  late  in  the  fall  do  you  find,  the  codling  larvae  in  the  apple? 
Where  do  these  larvae  go  when  they  leave  the  apple? 

Work  to  be  done  in  March  or  early  April — Visit  an  orchard  and  look 
under  the  loose  bark  on  old  trees,  or  along  protected  sections  of  fences  or 
brush  piles  and  bring  in  all  the  cocoons  you  can  find.  Do  not  injure  the 
cocoons  by  tearing  them  from  the  places  where  they  are  woven,  but  bring 
them  in  on  bits  of  the  bark  or  other  material  to  which  they  are  attached. 

1.  How  does  the  cocoon  look  outside  and  inside?  What  is  in  the 
cocoon?  Why  was  the  cocoon  made?  When  was  it  made? 

2.  Place  the  cocoons  in  a box  covered  with  cheese-cloth  and  place 
the  box  out  of  doors  where  the  contents  can  be  frequently  observed  and 
make  the  following  notes: 

3.  When  does  the  larva  change  to  the  pupa?  Describe  the  pupa. 
How  does  the  cocoon  look  after  the  moth  issues  from  it? 

4.  Describe  the  moth,  noting  color  of  head,  thorax,  body,  front  and 
hind  wings? 

5.  If  these  moths  were  free  to  fly  around  the  orchard,  when  and 
where  would  they  lay  their  eggs? 

6.  When  should  the  trees  be  sprayed  to  kill  the  young  codling  moth? 
With  what  should  they  be  sprayed?  Why  should  they  not  be  sprayed 
during  the  blossoming  period?  Why  not  after  the  calyx  closes? 


Almost  too  late  to  spray.  The  apples  on  each  side  have  the  calyx 
lobes  nearly  drawn  together.  The  pear  in  the  middle 
still  has  the  calyx  cavity  open.

LEAF-MINERS 

Teacher's  Story 

“ And  there's  never  a leaf  nor  a blade  too  mean 
To  be  some  happy  creature's  palace". 

— Lowell. 

AY  not  Lowell  have  had  in  mind,  when  he  wrote 
these  lines,  the  canny  little  creatures  which 
find  sustenance  for  "their  complete  growth 
between  the  upper  and  lower  surfaces  of  a leaf, 
which  seems  to  us  as  thin  as  a sheet  of  paper. 
To  most  children,  it  seems  quite  incredible 
that  there  is  anything  between  the  upper  and 
lower  surfaces  of  a leaf,  and  this  lesson  should 
hinge  on  the  fact  that  in  every  leaf,  however 
thin,  there  are  rows  of  cells  containing  the 
living  substance  of  the  leaf,  with  a wall  above 
and  a wall  below  to  protect  them.  Some  of  the  smaller  insects  have 
discovered  this  hidden  treasure,  which  they  mine  while  safely  protected 
from  sight,  and  thus  make  strange  figures  upon  the  leaves. 

Among  the  most  familiar  of  these  are  the  serpentine  mines,  so  called 
because  the  figure  formed  by  the  eating  out  of  the  green  pulp  of  the 
leaf,  curves  like  a serpent.  These  mines  are  made  by  the  caterpillars 
of  tiny  moths,  which  have  long  fringes  upon  the  hind  wfings.  The  life 
story  of  such  a moth  is  as  follows:  The  little  moth,  whose  expanded 

wings  measure  scarcely  a quarter  of  an  inch  across,  lays  an  egg  on  the 
leaf;  from  this,  there  hatches  a tiny  caterpillar  that  soon  eats  its  way 
into  the  midst  of  the  leaf.  In  shape,  the  caterpillar  is  somewhat  “square 
built,”  being  rather  stocky  and  wide  for  its  length;  it  feeds  upon  the 
juicy  tissues  of  the  leaf  and  divides,  as  it  goes,  the  upper  from  the  lower 
surface  of  the  leaf;  and  it  teaches  us,  if  we  choose  to  look,  that 
these  outer  walls  of  the  leaf  are  thin,  colorless,  and  paper-like.  We  can 
trace  the  whole  life  history  and  wanderings  of  the  little  creature,  from 
the  time  wThen,  as  small  as  a pin  point,  it  began  to  feed,  until  it 
t* stained  its  full  growth.  As  it  increased  in  size,  its  appetite  grew  larger 
also,  and  these  two  forces  working  together  naturally  enlarged  its  house. 
When  finally  the  little  miner  gets  its  growth,  it  makes  a rather  larger 
and  more  v,2>mmodious  room  at  the  end  of  its  mine,  which  to  us  looks  like 


Insect  Study 


353 


the  head  of  the  serpent ; here  it 
changes  to  a pupa,  perhaps  after 
nibbling  a hole  with  its  sharp  little 
jaws,  so  that  when  it  changes  to  a 
soft,  fluffy  little  moth  with  mouth 
unfitted  for  biting,  it  is  able  to  escape. 

In  some  species,  the  caterpillar  comes 
out  of  the  mine  and  goes  into  the 
ground  to  change  to  a pupa.  By 
holding  up  to  the  light  a leaf  thus 
mined,  we  can  see  why  this  little  chap 
was  never  obliged  to  clean  house;  it 
mined  out  a new  room  every  day,  and 
left  the  sweepings  in  the  abandoned 
mine  behind.  Mines  of  this  sort  are 
often  seen  on  the  leaves  of  nastur- 
tium, the  smooth  pigweed,  columbine, 
and  many  other  plants.  There  are 
mines  of  many  shapes,  each  form 
being  made  by  a different  species  of 
insect.  Some  flare  suddenly  from  a 
point  and  are  trumpet-shaped  while 
some  are  mere  blotches.  The  blotch 
mines  are  made,  through  the  habits  of 
the  insect  within  them ; it  feeds  around 
and  around,  instead  of  forging  ahead, 
as  is  the  case  with  the  serpentine  miners, 
flies  and  moths  may  mine  leaves,  each 
special  food  plant.  Most  of  the  smaller  leaf  mines  are  made 
by  the  caterpillars  of  the  moths,  which  are  fitly  called  the  Tineina 
or  Tineids.  Most  of  these  barely  have  a wing  expanse  that  will 
reach  a quarter  of  an  inch  and  many  are  much  smaller;  they  all  have 
narrow  wings,  the  hind  wings  being  mere  threads  bordered  with 
beautiful  fringes.  The  specific  names  of  these  moths  usually  end  in 

“ella;”  thus,  the  one  that  mines  in 
apple  is  malifoliella,  the  one  in  grain  is 
granella.  One  of  these  little  moths, 
Gelechia  pinifoliella  lives  the  whole 
of  its  growing  life  in  half  of  a pine 
needle.  The  moth  lays  the  egg  at 
about  the  middle  of  the  needle,  and 
the  little  caterpillar  that  hatches  from 
it,  gnaws  its  way  directly  into  the  heart 
of  the  needle;  and  there,  as  snug 
as  snug  can  be,  it  lives  and  feeds  until 
it  is  almost  a quarter  of  an  inch 
long,  think  of  it ! Many  a time  I have 
held  up  to  the  light  a pine  needle 
thus  inhabited,  and  have  seen  the  little 
miner  race  up  and  down  its  abode 
as  if  it  knew  that  something  was  hap- 
pening. When  it  finally  attains  its 


Serpentine  mines  in  nasturtium

growth  it  makes  wider  the  little  door,  through  which  it  entered ; it  does 
this  very  neatly,  the  door  is  an  even  oval,  and  looks  as  if  it  were  made 
with  the  use  of  dividers.  After  thus  opening  the  door,  the  caterpillar 
changes  to  a little,  long  pupa,  very  close  to  its  exit;  and  later  it  emerges, 
as  an  exquisite  little  moth  with  silvery  bands  on  its  narrow,  brown  wings, 

and  a luxurious  fringe 
on  the  edges  of  its 
narrow,  hind  wings 
and  also  on  the  outer 
hind  edges  of  the  front 
wings. 

The  gross  mines  in 
the  leaves  of  dock  and 
beet  are  not  pretty. 
The  poor  leaves  are 
slitted,  sometimes  for 
their  whole  length, 
and  soon  turn  brown 
and  lie  prone  on  the 
ground,  or  dangle 
pathetically  from  the 
stalk.  These  mines 
are  made  by  the  larvae 
of  a fly,  and  a whole 
family  live  in  the 
same  habitation.  If 
we  hold  a leaf  thus 
mined  up  to  the  light, 
while  it  is  still  green, 
we  can  see  several  of 
the  larvae  working,

vegetable  in  these  viands.  The  flies,  who  thus  take  our  greens  ahead  of 
us,  are  perhaps  a little  larger  than  house-flies,  and  are  generally  gray  in 
color  with  the  front  of  the  head  silver-white.  These  insects  ought  to 
teach  us  the  value  of  clean  culture  in  our  gardens,  since  they  also  mine  in 
the  smooth  pigweed.

LESSON  LXXVII 
Leaf-miners 

Leading  thought — The  serpent-like  markings  and  the  blister-like 
blotches  which  we  often  see  on  leaves  are  made  by  the  larvae  of  insects 
which  complete  their  growth  by  feeding  upon  the  inner  living  substance 
of  the  leaf. 

Method — The  nasturtium  leaf -miner  is  perhaps  the  most  available  for 
this  lesson  since  it  may  be  found  in  its  mine  in  early  September.  How- 
ever, the  pupils  should  bring  to  the  .schoolroom  all  the  leaves  with  mines 
in  them,  that  they  can  find  and  study  the  different  forms. 

Observations — i . Sketch  the  leaf  with  the  mine  in  it,  showing  the  shape 
of  the  mine.  What  is  the  name  of  the  plant  on  which  the  leaf  grew? 

2.  Hold  the  leaf  up  to  the  light,  can  you  see  the  insect  within  the 
mine?  What  is  it  doing?  Are  there  more  than  one  insect  in  the  mine? 
Open  the  mine  and  see  how  the  miner  looks. 

3.  There  are  three  general  types  of  mines:  Those  that  are  long, 

curving  lines  called  serpentine  mines;  those  that  begin  small  and  flare 
out,  called  trumpet  mines;  and  those  that  are  blister-lilce  called  blotch 
mines.  Which  of  these  is  the  mine  you  are  studying? 

4.  Study  a serpentine  mine.  Note  that  where  the  little  insect  began 
to  eat,  the  mine  is  small.  Why  does  it  widen  from  this  point?  What 
happened  in  the  part  which  we  call  the  serpent’s  head? 

5.  Look  closely  with  a lens  and  find  if  there  is  a break  above  the  mine 
in  the  upper  surface  of  the  leaf  or  below  the  mine  in  the  lower  surface  of 
the  leaf?  If  the  insect  is  no  longer  in  the  mine  can  you  find  where  it 
escaped?  Can  you  find  a shed  pupa-skin  in  the  “serpent’s  head?” 

6.  Why  does  an  insect  mine  in  a leaf?  What  does  it  find  to  eat? 
How  is  it  protected  from  the  birds  or  insects  of  prey  while  it  is  getting  its 
growth  ? 

7.  Look  on  leaves  of  nasturtium,  columbine,  lamb’s  quarters,  dock 
and  burdock,  lor  serpentine  mines.  Are  the  mines  on  these  different 
plants  alike?  Do  you  suppose  they  are  made  by  the  same  insect? 

8.  Look  on  leaves  of  dock,  burdock,  beet  and  spinach  for  blotch 
mines.  Are  there  more  than  one  insect  in  these  mines  ? If  the  insects  are 
present,  hold  the  leaf  out  to  the  light  and  watch  them  eat. 

9.  Look  in  the  leaves  of  pitch  or  other  thick  leaved  pines  (not  white 
pine),  for  pine  needles  which  are  yellow  at  the  tip.  Examine  these  for 
miners.  If  the  miner  is  not  within,  can  you  find  the  little  circular  door

by  which  it  escaped?  Would  you  think  there  was  enough  substance  in  a 
half  a pine  needle  to  support  a little  creature  while  it  grew  up  ? 

io.  If  you  find  leaf -miners  at  work,  do  not  pluck  off  the  leaves  being 
mined  but  cover  each  with  a little  bag  of  swiss  muslin  tied  close  about  the 
petiole  and  thus  capture  the  winged  insect.

THE  LEAF-ROLLERS 
Teacher's  Story 

' we  look  closely  at  sumac  leaves  before  they  are 
aflame  from  autumn’s  torch,  we  find  many  of  the 
leaflets  rolled  into  little  cornucopias  fastened  with 
silk.  The  silk  is  not  in  a web,  like  that  of  the 
spider,  but  the  strands  are  twisted  together, 
hundreds  of  threads  combined  in  one  strong 
cable,  and  these  are  fastened  from  roll  to  leaf, 
like  tent  ropes.  If  we  look  at  the  young  bass- 
woods, we  find  perhaps  many  of  their  leaves  cut 
across,  and  the  flap  made  into  a roll  and  likewise 
fastened  with  silken  ropes.  The  witch-hazel, 
which  is  a veritable  insect  tenement,  also  shows 
these  rolls.  In  fact,  we  may  find  them  upon  the 
leaves  of  almost  any  species  of  tree  or  shrub,  and 
each  of  these  rolls  has  its  own  special  maker  or  indweller.  Each  species 
of  insect,  which  rolls  the  leaves,  is  limited  to  the  species  of  plant  on  which 
it  is  found ; and  one  of  these  caterpillars  would  sooner  starve  than  take  a 
mouthful  from  a leaf  of  any  other  plant.  Some  people  think  that  insects 
will  eat  anything  that  comes 
in  their  way ; but  of  all 
created  animals,  insects  are 
the  most  fastidious  as  to  their 
food. 

Some  species  of  leaf -rollers 
unite  several  leaflets  together, 
while  others  use  a single  leaf. 

In  the  case  of  the  sumac  leaf- 
roller,  it  begins  in  a single  leaf; 
but  in  its  later  stages,  it 
fastens  together  two  or  three 
of  the  terminal  leaflets  in  order 
to  gain  more  pasturage.  The 
little  silken  tent  ropes  which 
hold  the  folded  leaves  are  well 
worth  study  with  a lens. 

They  are  made  of  hundreds  of 
threads  of  the  finest  silk, 
woven  from  a gland  opening 
near  the  lower  lip  of  the  cater- 
pillar. The  rope  is  always 
larger  where  it  is  attached  to 
the  leaf  than  at  the  center, 
because  the  caterpillar  criss- 
crosses the  threads  in  order  to  Leaf-rollers  in  sumac,  with  diagram  showing  the

leaf  larger  and  firmer.  Unroll  a tent  carefully,  and  you  may  see  the 
fastenings  used  in  an  earlier  stage,  and  may  even  find  the  first  turned-down 
edge  of  the  leaf.  However,  the  center  of  a leaf  roller’s  habitation  is 
usually  very  much  eaten,  for  the  whole  reason  for  making  its  little  house

Handbook  of  Nature-Study 


is  that  the  soft-bodied  caterpillar  may  eat  its  fill  completely  hidden  from 
the  eyes  of  birds  or  other  animals.  When  it  first  hatches  from  the  egg,  it 
feeds  for  a short  time,  usually  on  the  under  side  of  the  leaf ; but  when  still 
so  small  that  we  can  barely  see  it  with  the  naked  eye,  it  somehow  manages 
to  fold  over  itself  one  edge  of  the  leaf  and  peg  it  down.  The  problem  of 
how  so  small  a creature  is  able  to  pull  over  and  fold  down  or  to  make  in  a 
roll  a stiff  leaf  is  hard  to  solve.  I,  myself,  believe  it  is  done  by  making 
many  threads,  each  a little  more  taut  than  the  last.  I have  watched 
several  species  working,  and  the  leaf  conies  slowly  together  as  the  cater- 
pillar stretches  its  head  and  sways  back  and  forth  hundreds  of  times, 
fastening  the  silk  first  to  one  side  and  then  to  the  other.  Some  observers 
believe  that  the  caterpillar  throws  its  weight  upon  the  silk,  in  order  to 
pull  the  leaf  together;  but  in  the  case  of  the  sumac  leaf-roller,  I am  sure 

this  is  not  true,  as  I have 
watched  the  process 
again  and  again  under  a 
lens,  and  could  detect 
no  signs  of  this  method. 
Many  of  the  caterpillars 
which  make  rolls,  change  to 
small  moths  known  as 
Tortricids.  This  is  a very  large 
family,  containing  a vast  number 
of  species  and  not  all  of  the 
members  are  leaf-rollers.  These 
little  moths  have  the  front  wings 
rather  wide  and  more  or  less  rectangular  in 
outline.  The  entomologists  have  a pleasing 
fashion  of  ending  the  names  of  all  of  these 
moths  with  “ana;”  the  one  that  rolls  the 
currant  leaves  is  Rosana,  the  one  on 
juniper  is  Rutilana,  etc.  Since  many  of  the 
caterpillars  of  this  family  seek  the  ground  to 
pupate  and  do  not  appear  as  moths  until  the 
following  spring,  it  is  somewhat  difficult  to 
study  their  complete  life  histories,  unless  one 
has  well-made  breeding  cages  with  earth  at 
the  bottom ; and  even  then  it  is  difficult  to 
keep  them  under  natural  conditions,  since  in 
an  ordinary  living  room  the  insects  dry  up 
and  do  not  mature.

LESSON  LXXVIII 
The  Leaf-rollers 

Leading  thought — There  are  many  kinds  of  insects  which  roll  the 
leaves  of  trees  and  plants  into  tents,  in  which  they  dwell  and  feed  during 
their  early  stages. 

Method — This  is  an  excellent  lesson  for  early  autumn  wdien  the  pupils 
may  find  many  of  these  rolled  leaves,  which  they  may  bring  to  the  school- 
room, and  which  will  give  material  for  the  lesson.  The  rolls  are  found 
plentifully  on  sumac,  basswood  and  wdtch-hazel. 

Observations — i.  What  is  the  name  of  the  trees  and  shrubs  from 
which  these  rolled  leaves  which  you  have  collected  were  taken? 

2.  Are  more  than  one  leaf  or  leaflet  used  in  making  the  roll? 

3.  Is  the  leaf  rolled  crosswise  or  lengthwise?  How  large  is  the  tube 
thus  made? 

4.  Is  the  nest  in  the  shape  of  a tube,  or  are  several  leaves  fastened 
together,  making  a box-shaped  nest*? 

5.  How  is  the  roll  made  fast?  Examine  the  little  silken  ropes  with 
a lens  and  describe  one  of  them.  Is  it  wider  where  it  is  attached  to  the 
leaf  than  at  the  middle?  Why? 

6.  How  many  of  these  tent  ropes  are  there  which  make  fast  the  roll? 
Unroll  a leaf  carefully  and  see  if  you  can  find  signs  of  the  tent  ropes  that 
fastened  the  roll  tqgether  wrhen  it  was  smaller.  Can  you  find  where  it 
began  ? 

7.  As  you  unroll  the  leaves  what  do  you  see  at  the  center?  Has  the 
leaf  been  eaten?  Can  you  discover  the  reason  why  the  caterpillar  made 
this  roll  ? 

8.  How  do  you  think  a caterpillar  manages  to  roll  a leaf  so  success- 
fully ? Wliere  is  the  spinning  gland  of  a caterpillar  ? How  does  the  insect 
act  when  spinning  threads  back  and  forth  when  rolling  the  leaf?  What 
sort  of  insect  does  the  caterpillar  which  rolls  the  leaf  change  into?  Do 
you  suppose  that  the  same  kind  of  caterpillars  makes  the  rolls  on  two 
different  species  of  trees? 

9.  In  July  or  early  August  get  some  of  the  rolls  with  the  caterpillars 
in  them,  unroll  a nest,  take  the  caterpillar  out  and  put  it  on  a fresh  leaf 
of  the  same  kind  of  tree  or  shrub  on  which  you  found  it,  and  watch  it 
make  its  roll.

THE  GALL-DWELLERS 

He  retired  to  his  chamber,  took  his  lamp,  and  summoned  the  genius  as  usual. 
“ Genius ,”  said  he, “build  me  a palace  near  the  sultan' s,  fit  for  the  reception  of  my  spouse, 
the  princess;  but  instead  of  stone,  let  the  walls  be  formed  of  massy  gold  and  silver,  laid, 
in  alternate  rows;  and  let  the  interstices  be  enriched  with  diamonds  and  emeralds.  The 
palace  must  have  a delightful  garden,  planted  with  aromatic  shrubs  and  plants,  bearing 
the  most  delicious  fruits  and  beautiful  flowers.  But,  in  particular,  let  there  be  an 
immense  treasure  of  gold  and  silver  coin.  The  palace,  moreover,  must  be  well  provided 
with  offices,  storehouses,  and  stables  full  of  the  finest  horses,  and  attended  by  equerries, 
grooms,  and  hunting  equipage .”  By  the  dawn  of  the  ensuing  morning,  the  genius 
presented  himself  to  Aladdin,  and  said,  “Sir,  your  palace  is  finished;  come  and  see  if  it 
accords  with  your  wishes .” — Arabian  Nights  Entertainments. 

LTHOIJGH  Aladdin  is  out  of  fashion,  we  still 
have  houses  of  magic  that  are  even  more 
wonderful  than  that  produced  by  his  resource- 
ful lamp.  These  houses  are  built  through  an 
occult  partnership  between  insects  and  plant 
tissues ; and  no  one  understands  just  how  they 
are  made,  although  we  are  beginning  to 
understand  a little  concerning  the  reasons  for 
the  growth.  These  houses  are  called  galls 
and  are  thus  well  named,  since  they  grow 
because  of  an  irritation  to  the  plant  caused 
by  the  insect. 

There  are  many  forms  of  these  gall-dwellings,  and  they  may  grow  upon 
the  root,  branch,  leaf,  blossom,  or  fruit.  The  miraculous  thing  about 
them  is  that  each  kind  of  insect  builds  its  magical  house  on  a certain  part 
of  a certain  species  of  tree  or  plant ; and  the  house  is  always  of  a certain 
definite  form  on  the  outside  and  of  a certain  particular  pattern  within. 
Many  widely  differing  species  of  insects  are  gall-makers;  and  he  who  is 
skilled  in  gall  lore  knows,  when  he  looks  at  the  outside  of  the  house,  just 
what  insect  dwells  within  it.

We  may  take  the  history  of  the  common  oak  apple,  as  an  example. 
A little,  four-winged,  fly-like  creature  lays  its  eggs,  early  in  the  season, 
on  the  leaf  of  the  scarlet  oak.  As  soon  as  the  larva  hatches,  it  begins  to 

eat  into  the  substance  of 
one  of  the  leaf  veins.  As  it 
eats,  it  discharges  through 
its  mouth  into  the  tissues 
of  the  leaf,  a substance 
which  is  secreted  from 
glands  within  its  body. 
Immediately  the  building 
of  the  house  commences; 
out  around  the  little  crea- 
ture grow  radiating  vegeta- 
ble fibers,  showing  by  their 
position  plainly  that  the 
grub  is  the  center  of  all  of 
this  new  growth ; mean- 
while, a smooth,  thin  cover- 
ing completely  encloses  the 
globular  house;  larger  and 
larger  grows  the  house 
until  we  are  accustomed 
to  call  it  an  oak  apple,  so 
large  is  it.  The  little  chap 
inside  is  surely  content  and 
happy, ' for  it  is  protected  from  the  sight  of  all  of  its  enemies,  and  it 
fiflds  the  wralls  of  its  house  the  best  of  food.  It  is  comparable  to  a boy 
living  in  the  middle  of  a giant  sponge  cake,  and  who  when  hungry  would 
naturally  eat  out  a larger  cave  in  the  heart  of  the  cake.  After  the  inmate 
of  the  oak  apple  completes  its  growth,  it  changes  to  a pupa  and  finally 
comes  out  into  the  world  a tiny  four -winged  fly,  scarcely  a quarter  of  an 
inch  in  length. 

The  story  of  the  willow  cone-gall  is  quite  different.  A little  gnat  lays 
her  eggs  on  the  tip  of  the  bud  of  a twig;  as  soon  as  the  grub  hatches  and 
begins  to  eat,  the  growth  of  the  twig  is  arrested,  the  leaves  are  stunted 
until  they  are  mere  scales  and  are  obliged  to  overlap  in  rows  around  the 
little  inmate,  thus  making  for  it  a cone-shaped  house  which  is  very 
thoroughly  shingled.  The  inhabitant  of  this  gall  is  a hospitable  little 
fellow,  and  his  house  shelters  and  feeds  many  other  insect  guests.  He 
does  not  pay  any  attention  to  them,  being  a recluse  in  his  own  cell,  but 
he  civilly  allows  them  to  take  care  of  themselves  in  his  domain,  and 
feed  upon  the  walls  of  his  house.  He  stays  in  his  snug  home  all  winter 
and  comes  out  in  the  spring  a tiny,  two-winged  fly. 

There  are  two  galls  common  on  the  stems  of  goldenrod.  The  more 
numerous  is  spherical  in  form  and  is  made  by  a fat  and  prosperous 
looking  little  grub  which  later  develops  into  a fly.  But  although  it 
is  a fly  that  makes  the  globular  gall  in  the  stem  of  goldenrod,  the 
spindle-shaped  gall  often  seen  on  the  same  stem  has  quite  another 
story.  A little  brown  and  gray  mottled  moth,  about  three-fourths  of  an 
inch  long,  lays  her  egg  on  the  stem  of  the  young  goldenrod.  The  cater- 
pillar, when  it  hatches,  lives  inside  the  stem,  which  accommodatingly

enlarges  into  an  oblong  room.  The  caterpillar  feeds  upon  the  substance 


of  the  stem  until  it  attains  its  growth, 
something  about  its  future  needs.  At 
least  it  cuts,  with  its  sharp  jaws,  a little 
oval  door  at  the  upper  end  of  its  house 
and  makes  an  even  bevel  by  widening 
the  opening  toward  the  outside.  It 
then  makes  a little  plug  of  debris 
which  completely  fills  the  door;  but 
because  of  the  bevel,  no  intrusive 
beetle  or  ant  can  push  it  in.  Thus 
the  caterpillar  changes  to  a helpless 
pupa  in  entire  safety ; and  when  the 
little  moth  issues  from  the  pupa  skin, 
all  it  has  to  do  is  to  push  its  head 
against  the  door,  and  out  it  falls,  and

the  recluse  is  now  a creature 
of  the  outside  world. 

Many  galls  are  compound, 
that  is,  they  are  made  up 
of  a community  of  larvae, 
each  in  its  own  cell.  The 
mossy  rose-gall  is  an  instance 
of  this.  The  galls  made  by 
mites  and  aphids  are  open 
either  below  or  above  the 
surface  of  the  leaf;  the  little 
conical  galls  on  witch-hazel 
are  examples  of  these.  In.  fact,  each  gall  has 
its  own  particular  history,  which  proves  a 
most  interesting  story  if  we  seek  to  read  it 
with  our  own  eyes.

own  peculiar  gall  on  a certain  species  of  plant,  and  no  one  understands 
just  how  this  is  done  or  why  it  is  so. 

Method — Ask  the  pupils  to  bring  in  as  many  of  these  galls  as  possible. 
Note  that  some  have  open  doors  and  some  are  entirely  closed.  Cut  open 
a gall  and  see  what  sorts  of  insects  are  found  within  it.  Place  each 

kind  of  gall  in  a 
tumbler  or  jar 
covered  with  cheese- 
cloth and  place 
where  they  may  be 
under  observation 
for  perhaps  several 
months;  note  what 
sort  of  winged  insect 
comes  from  each.

3.  Open  the  gall;  is  there  an  insect 
within  it?  If  so,  where  is  it  and  how  does 
it  look?  What  is  the  appearance  of  the 
inside  of  the  gall?

very  center  of  the  gall,  or  are  there  many 
such  cells  ? 

5.  Has  the  house  an  open  door?  If 
so,  does  the  door  open  above  or  below? 
Are  there  more  than  one  insect  in  the 
galls  with  open  doors?  What  sort  of  in- 
sect makes  this  kind  of  house?

are  they  doing?

their  little  inmates?  How  do  they  pro-

8.  Do  the  gall  insects  live  all  their 
lives  within  the  galls  or  do  they  change  to 
winged  insects  and  come  out  into  the 
world?  If  so,  how  do  they  get  out?

THE  GRASSHOPPER 
Teacher's  Story 

ECAUSE  the  grasshopper  affords  special  facilities 
for  the  study  of  insect  structure,  it  has  indeed 
become  a burden  to  the  students  in  the  labora- 
tories of  American  universities.  But  in  nature- 
study  we  must  not  make  anything  a burden, 
least  of  all  the  grasshopper,  which  being  such  a 
famous  jumper  as  well  as  flier,  does  not  long 
voluntarily  burden  any  object. 

Since  we  naturally  select  the  most  salient 
characteristic  of  a creature  to  present  first  to 
young  pupils,  we  naturally  begin  this  lesson  with 
the  peculiarity  which  makes  this  insect  a “grass- 
hopper. ’ ’ When  any  creature  has  unusually  strong 
hind  legs,  we  may  be  sure  it  is  a jumper,  and  the 
grasshopper  shows  this  peculiarity  at  first  glance.  The  front  legs  are 
short,  the  middle  legs  a trifle  longer,  but  the  femur  of  the  hind  leg  is 
nearly  as  long  as  the  entire  body,  and  contains  many  powerful  muscles 
which  have  the  appearance  of  being  braided,  because  of  the  way  they  are 
attached  to  the  skeleton  of  the  leg ; the  tibia  of  the  hind  leg  is  long  and  as 
stiff  as  if  made  of  steel.  When  getting  ready  to  jump  the  grasshopper 
lowers  the  great  femur  below  the  level  of  the  closed  wings  and  until  the 
tibia  is  parallel  with  it  and  the  entire  foot  is  pressed  against  the  ground.

3 66 


Handbook  of  Nature-Study 


The  pair  of  double  spines  at  the  end  of  the  tibia,  just  back  of  the  foot,  are 
pressed  against  the  ground  like  a spiked  heel,  and  the  whole  attitude  of 
the  insect  is  tense.  Then,  like  a steel  spring,  the  long  legs  straighten  and 
the  insect  is  propelled  high  into  the  air  and  far  away.  This  is  a remark- 
able example  of  insect  dynamics;  and  since  so  many  species  of  birds  feed 
upon  the  grasshopper,  its  leaping  power  is  much  needed  to  escape  them. 
However,  when  the  grasshopper  makes  a journey  it  uses  its  wings. 

As  we  watch  a grasshopper  crawling  up  the  side  of  a vial  or  tumbler  we 
can  examine  its  feet  with  a lens.  Between  and  in  front  of  the  claws  is 
an  oval  pad  which  clings  to  the  glass,  not  by  air  pressure  as  was  once  sup- 
posed, but  by  means  of  microscopic  hairs,  called  tenent  hairs,  which  secrete 
a sticky  fluid.  Each  foot  consists  of  three  segments  and  a claw;  when 
the  insect  is  quiet,  the  entire  foot  rests  upon  the  ground  ; but  when 
climbing  on  glass,  the  toe  pads  are  used. 

The  grasshopper’s  face  has  a droll  expression;  would  that  some  carica- 
turist could  analyze  it ! It  is  a long  face,  and  the  compound  eyes  placed 
high  upon  it,  give  a look  of  solemnity.  The  simple  eyes  can  be  made  out 
with  a lens.  There  is  one  just  in  front  of  each  big  eye,  and  another,  like 
the  naughty  little  girl’s  curl,  is  “right  in  the  middle  of  the  forehead.” 
The  antennae  are  short  but  alert.  The  two  pairs  of  palpi  connected  with 
the  mouth-parts  are  easily  seen,  likewise  the  two  pairs  of  jaws,  the  notched 
mandibles  looking  like  a pair  of  nippers.  We  can  see  these  jaws  much

better  when  the  insect  is  eating,  which  act  is  done  methodically.  First,  it 
begins  at  one  edge  of  a leaf,  which  it  seizes  between  the  front  feet  so  as  to 
hold  it  firm;  it  eats  by  reaching  up  and  cutting  downwards,  making  an 
even-edged,  long  hole  on  the  leaf  margin;  the  hole  is  made  deeper  by 
repeating  the  process.  It  sometimes  makes  a hole  in  the  middle  of  a leaf 
and  bites  in  any  direction,  but  it  prefers  to  move  the  jaws  downward. 
While  it  is  feeding,  its  palpi  tap  the  leaf  continually  and  its  whole  atti- 
tude is  one  of  deep  satisfaction.  There  is  an  uprolled  expression  to  the 
compound  eyes  which  reminds  us  of  the  way  a child  looks  over  the  upper 
edge  of  its  cup  while  drinking  milk.  The  grasshopper  has  a preference 
for  tender  herbage,  but  in  time  of  drouth  will  eat  almost  any  living  plant. 

Back  of  the  head  is  a sun-bonnet-shaped  piece,  bent  down  at  the  sides, 
forming  a cover  for  the  thorax.  The  grasshopper  has  excellent  wings,  as 
efficient  as  its  legs;  the  upper  pair  are  merely  strong,  thick,  membranous 
covers,  bending  down  at  the  sides  so  as  to  protect  the  under  wings;  these 
wing-covers  are  not  meant  for  flying  and  are  held  stiff  and  straight  up  in 
the  air,  during  flight.  The  true  wings,  when  the  grasshopper  is  at  rest,  are 
folded  lengthwise  like  a fan  beneath  the  wing-covers;  they  are  strongly 
veined  and  circular  in  shape,  giving  much  surface  for  beating  the  air. 
The  grasshoppers’  flight  is  usually  swift  and  short ; but  in  years  of  famine

they  fly  high  in  the  air  and  for  long  distances,  a fact  recorded  in  the  Bible 
regarding  the  plague  of  locusts.  When  they  thus  appear  in  vast  hordes, 
they  destroy  all  the  vegetation  in  the  region  where  they  settle. 

The  wings  of  grasshoppers  vary  in  color,  those  of  the  red-legged  species 
being  gray,  while  those  of  the  Carolina  locusts  are  black  with  yellow  edges. 
The  abdomen  is  segmented,  as  in  all  insects,  and  along  the  lower  side  there 
are  two  lengthwise  sutures  or  creases  which  open  and  shut  bellows-like, 
when  the  grasshopper  breathes.  The  spiracles  or  breathing  pores  can  be 
seen  on  each  segment,  just  above  this  suture. 

The  grasshopper  has  its  ears  well  protected;  to  find  them,  we  must 
lift  the  wings  in  order  to  see  the  two  large  sounding  disks,  one  on  each  side 
of  the  first  segment  of  the  abdomen.  These  are  larger  and  much  more 
like  ears  than  are  the  little  ears  in  the  elbows  of  the  katydids. 

The  singing  of  the  short-horned  grasshoppers  is  a varied  performance, 
each  species  doing  it  in  its  own  way.  One  species  makes  a most  seductive 
little  note  by  placing  the  femur  and  tibia  of  the  hind  legs  together,  and 
with  the  hind  feet  completely  off  the  ground,  the  legs  are  moved  up  and 
down  with  great  rapidity,  giving  off  a little  purr.  The  wings  in  this  case, 
do  not  lift  at  all.  There  are  other  species  that  make  the  sound  by  rubbing 
the  legs  against  the  wing-covers. 

The  grasshopper  makes  its  toilet  thus : It  cleans  first  the  hind  feet  by 

rubbing  them  together  and  also  by  reaching  back  and  scrubbing  them 
with  the  middle  feet;  the  big  hind  femur  it  polishes  with  the  bent  elbow 
of  the  second  pair  of  legs.  It  cleans  the  middle  feet  by  nibbling  and 
licking  them,  bending  the  head  far  beneath  the  body  in  order  to  do  it.  It 
polishes  its  eyes  and  face  with  the  front  feet,  stopping  to  lick  them  clean 
between  whiles,  and  it  has  a most  comical 
manner  of  cleaning  its  antennae;  this  is 
accomplished  by  tipping  the  head  sidewise, 
and  bending  it  down  so  that  the  antenna  of 
one  side  rests  upon  the  floor;  it  then  plants 
the  front  foot  of  that  side  firmly  upon  the 
antenna  and  pulls  it  slowly  backward  between 
the  foot  and  floor. 

The  grasshopper  has  some  means  of  defence 
as  well  as  of  escape ; it  can  give  a painful  nip 
with  its  mandibles;  and  when  seized,  it  emits 
copiously  from  the  mouth  a brownish  liquid 
which  is  acrid  and  ill- smelling.  This  performance  interests  children, 
who  are  wont  to  seize  the  insect  by  its  jumping  legs  and  hold  it  up, 
commanding  it  to  “chew  tobacco.” 

Grasshoppers  are  insects  with  incomplete  metamorphosis,  which 
merely  means  that  the  baby  grasshopper,  as  soon  as  it  emerges  from  the 
egg,  is  similar  in  form  to  its  parent  except  that  it  has  a very  large  head 
and  a funny  little  body,  and  that  it  has  no  quiet  stage  during  life.  When 
immature,  the  under  wings  or  true  wings  have  a position  outside  of  the 
wing-covers  and  look  like  little  fans. 

The  short-horned  grasshoppers  lay  their  eggs  in  oval  masses  protected 
by  a tough  overcoat.  The  ovipositor  of  the  mother  grasshopper  is  a very 
efficient  tool,  and  with  it  she  makes  a deep  hole  in  the  ground,  or  sometimes 
in  fence  rails  or  other  decaying  wood;  after  placing  her  eggs  in  such  a 
cavity,  she  covers  the  hiding  place  with  a gummy  substance  so  that  no

intruders  or  robbers  may  work  harm  to  her  progeny.  Most  species  of 
grasshoppers  pass  the  winter  in  the  egg  stage;  but  sometimes  we  find  in 
early  spring  the  young  ones  which  hatched  in  the  fall,  and  they  seem  as 
spry  as  if  they  had  not  been  frozen  stiff. 


LESSON  LXXX 

The  Red-Legged 
Grasshopper 

Leading  thought — The  grass 
hopper  feeds  upon  grass  and 
other  herbage  and  is  especially 
fitted  for  living  in  grassy  fields 
Its  color  protects  it  from  being 
seen  Dy  its  enemies  the  birds. 

If  attacked,  it  escapes  by  long 
jumps  and  by  flight.  It  can 
make  long  journeys  on  the  wing. 

Method — The  red-legged 
grasshopper  (M.  femur -rubrum ) 
has  been  selected  for  this  lesson 
because  it  is  the  most  common  of 
all  grasshoppers,  though  other 
species  may  be  used  as  well. 

The  red-legged  locust,  or  grass- 
hopper has,  as  is  indicated  by  its  name,  the  large  femur  of  the  hind  legs 
reddish  in  color.  Place  the  grasshopper  under  a tumbler  and  upon  a 
spray  of  fresh  herbage,  and  allow  the  pupils  to  observe  it  at  leisure.  It 
might  be  well  to  keep  some  of  the  grasshoppers  in  a cage  similar  to  that 
described  for  crickets.  When  studying  the  feet,  or  other  parts  of  the 
insect  requiring  close  scrutiny,  the  grasshopper  should  be  placed  in  a vial 
so  that  it  may  be  passed  around  and  observed  with  a lens.  Give  the 
questions  a few  at  a time,  and  encourage  the  pupils  to  study  these  insects 
in  the  field. 

Observations — i . Since  a grasshopper  is  such  a high  jumper,  discover 
if  you  can  how  he  does  this  “event.”  Which  pair  of  legs  is  the  longest? 
Which  the  shortest?  How  long  are  the  femur  and  tibia  of  the  hind  leg 
compared  with  the  body.  What  do  vou  think  gives  the  braided  appear- 
ance to  the  surface  of  the  hind  femur?  What  is  there  peculiar  about  the 
hind  femur?  Note  the  spines  at  the  end  of  the  tibia  just  behind  the  foot. 

2.  Watch  the  grasshopper  prepare  to  jump  and  describe  the  process. 
How  do  you  think  it  manages  to  throw  itself  so  far?  If  a man  were  as 
good  a jumper  as  a grasshopper  in  comparison  to  his  size,  he  could  jump 
300  feet  high  or  500  feet  in  distance.  Why  do  you  think  the  grasshopper 
needs  to  jump  so  far? 

3.  As  the  grasshopper  climbs  up  the  side  of  a tumbler  or  vial,  look  at 
its  feet  through  a lens  and  describe  them.  How  many  segments  are 
there?  Describe  the  claws.  How  does  it  cling  to  the  glass?  Describe 
the  little  pad  between  the  claws. 

4.  Look  the  grasshopper  in  the  face.  Where  are  the  compound  eyes 
situated?  Can  you  see  the  tiny  simple  eyes  like  mere  dots ? How  mar  y

are  there?  Where  are  they?  How  long  are  the  antennae?  For  what  are 
they  used  ? 

5.  How  does  a grasshopper  eat?  Do  the  jaws  move  up  and  down  or 
sidewise?  What  does  the  grasshopper  eat?  How  many  pairs  of  palpi 
can  you  see  connected  with  the  mouth- parts? 
How  are  these  used  when  the  insect  is  eating? 
When  there  are  many  grasshoppers,  what 
happens  to  the  crops? 

6.  What  do  you  see  just  back  of  the  grass- 
hopper’s head,  when  looked  at  from  above? 

7.  Can  the  grasshopper  fly  as  well  as 
jump?  How  many  pairs 
of  wings  has  it?  Does 
it  use  the  first  pair  of 
wings  to  fly  with  ? How 
does  it  hold  them  when 
flying?  Where  is  the 
lower  or  hind  pair  of 
wings  when  the  grass- 
hopper is  walking?  How 
do  they  differ  in  shape 
from  the  front  wings  ? 

8.  Note  the  abdomen.  It  is  made  of  many 
rings  or  segments.  Are  these  rings  continuous

does  it  show  that  it  is  offended? 

10.  How  does  the  grasshopper  per-

bodies  ? Do  some  have  antennae  longer 
than  their  bodies?  Where  are  the  long-

THE  KATYDID 
Teacher's  Story 

“7  love  to  hear  thine  earnest  voice  Thou  mindest  me  of  gentle  folks , 

Old  gentle  folks  are  they, 

Thou  say’st  an  undisputed  thing 
In  such  a solemn  way." 

— Holmes. 


Wherever  thou  art  hid, 
Thou  testy  little  dogmatist, 
Thou  pretty  katydid, 


ISTANCE,  however,  lends  enchantment  to  the  song  oi 
the  katydid,  for  it  grates  on  our  nerves  as  well  as  on 
our  ears,  when  at  close  quarters.  The  katydid  makes 
his  music  in  a manner  similar  to  that  of  the  cricket 
but  is  not,  however,  so  well  equipped  since  he  has 
only  one  file  and  onty  one  scraper  for  playing.  As 
with  the  meadow  grasshoppers  and  crickets,  only  the 
males  make  the  music,  the  wings  of  the  females  being 
delicate  and  normally  veined  at  the  base.  The  ears, 
too,  are  in  the  same  position  as  those  of  the  cricket, 
and  may  be  seen  as  a black  spot  in  the  front  elbow. 
The  song  is  persistent  and  may  last  the  night  long:  “Katy  did,  she  didn’t 

she  did.”  James  Whitcomb  Riley  says,  “The  katydid  is  rasping  at  the 
silence,”  and  the  word  rasping  well  describes  the  note. 

The  katydids  are  beautiful  insects,  with  green,  finely  veined,  leaf-like 
wing-covers  under  which  is  a pair  of  well  developed  wings,  folded  like 
fans;  they  resemble  in  form  the  long-horned  grasshoppers.  The  com- 
mon northern  species  ( Cyrtophyllus ) is  all  green  above  except  for  the 
long,  delicate,  fawn-colored  antennae  and  the  brownish  fiddle  of  the  male, 
which  consists  of  a flat  triangle  just  back  of  the  thorax  where  the  wing- 
covers  overlap.  Sometimes  this  region  is  pale  brown  and  sometimes 
green,  and  with  the  unaided  eye  we  can  plainly  see  the  strong  cross-vein, 
bearing  the  file.  The  green  eyes  have  darker  centers  and  are  not  so  large 
as  the  eyes  of  the  grasshopper.  The  body  is  green  with  white  lines  below 
on  either  side.  There  is  a suture  the  length  of  the  abdomen  in  which  are 
placed  the  spiracles.  The  insect  breathes  by  sidewise  expansion  and 
contraction,  and  the  sutures  rhythmically  open  and  shut;  when  they  are 
open,  the  spiracles  can  be  seen  as  black  dots.  The  legs  are  slender  and  the 
hind  pair,  very  long.  The  feet  are  provided  with  two  little  pads,  one  on 
each  side  of  the  base  of  the  claw.  In  the  grasshopper  there  is  only  one 
pad  which  is  placed  between  the  two  hooks  of  the  claw.  The  female  has 
a green,  sickle-shaped  ovipositor  at  the  end  of  the  body.  With  .his  she 
lays  her  flat,  oval  eggs,  slightly  over-lapping  in  a neat  row. 

The  katydids  are  almost  all  dwellers  in  trees  and  shrubs ; although  I 
have  often  found  our  common  species  upon  asters  and  similar  high  weeds. 
The  leaf-like  wings  of  these  insects  are,  in  form  and  color,  so  similar  to  the 
leaves  that  they  are  very  completely  hidden.  The  katydid  is  rarely  dis- 
covered except  by  accident;  although  when  one  is  singing,  it  may  be 
approached  and  ferreted  out  with  the  aid  of  a lantern. 

The  katydid, when  feeding,  often  holds  the  leaf  or  the  flower  firmly  with 
the  front  feet,  while  biting  it  off  like  a grazing  cow,  and  if  it  is  tough, 
chews  it  industriously  with  the  sidewise  working  jaws.  A katydid  will 
often  remain  quiet  a long  time  with  one  long  antenna  directed  forward 
and  the  other  backward,  as  if  on  the  lookout  for  news  from  the  front  and

the  rear.  But  when  the  katydid  “cleans  up,”  it  does  a thorough  job.  It 
nibbles  its  front  feet,  paying  special  attention 
to  the  pads,  meanwhile  holding  the  foot  to  its 
mandibles  with  the  aid  of  the  palpi.  But  once 
washing  is  not  enough;  I have  seen  a katydid 
go  over  the  same  foot  a dozen  times  in  succes- 
sion, beginning  always  with  the  hind  spurs  of 
the  tibia  and  nibbling  along  the  tarsus  to  the 
claws.  It  cleans  its  face  with  its  front  foot, 
drawing  it  downward  over  the  eye  and  then 
licking  it  clean.  It  cleans  its  antenna  with 
its  mandibles  by  beginning  at  the  base  and  drawing  it  up  in  a loop  as  fast 
as  finished.  After  watching  the  process  of  these  lengthy  ablutions,  we 
must  conclude  that  the  katydid  is  among  the  most  fastidious  members  of 
the  insect  “four  hundred.”

LESSON  LXXXI 

The  Katydid 

Leading  thought — The  katydids  resemble  the  long-horned  grasshoppers 
and  the  crickets.  They  live  in  trees,  and  the  male  sings  “katy-did”  by 
means  of  a musical  instrument  similar  to  that  of  the  cricket. 

Method — Place  a katydid  in  a cricket  cage  in  the  schoolroom,  giving  it 
fresh  leaves  or  flowers  each  day,  and  encouraging  the  pupils  to  watch  it  at 
recess.  It  may  be  placed  in  a vial  and  passed  around,  for  close  observa- 
tion. In  studying  this  insect,  use  the  lesson  on  the  red-legged  grass- 
hopper and  also  that  on  the  cricket.  These  lessons  will  serve  to  call  the 
attention  of  the  pupils  to  the  differences  and  resemblances  between  the 
katydid  and  these  two  allied  insects.

THE  BLACK  CRICKETS 

Of  the  insect  musicians  the  cricket  is  easily  the  most  popular.  Long  associated 
with  man,  as  a companion  of  the  hearth  and  the  field,  his  song  touches  ever  the 
chords  of  human  experience.  Although  we,  in  America,  do  not  have  the  house- 
cricket  which  English  poets  praise,  yet  our  field-crickets  have  a liking  for  warm 
corners,  and  will,  if  encouraged,  take  up  their  abode  among  our  hearthstones.  The 
greatest  tribute  to  the  music  of  the  cricket  is  the  wide  range  of  human  emotion  which 
it  expresses.  “As  merry  as  a cricket"  is  a very  old  saying  and  is  evidence  that  the 
cricket's  fiddling  has  ever  chimed  with  the  gay  moods  of  dancers  and  merrymakers. 
Again,  the  cricket's  song  is  made  an  emblem  of  peace;  and  again  we  hear  that  the 
cricket's  “ plaintive  cry"  is  taken  as  the  harbinger  of  the  sere  and  dying  year.  From 
happiness  to  utter  loneliness  is  the  gamut  covered  by  this  sympathetic  song.  Leigh 
Hunt  found  him  glad  and  thus  addresses  him: 

“ And  you,  little  housekeeper  who  class 
With  those  who  think  the  candles  come  too  soon. 

Loving  the  fre,  and  with  your  tricksome  tune 
Nick  the  glad,  silent  moments  as  they  pass."

THE  BLACK  CRICKET 
Teacher's  Story 

F we  wish  to  become  acquainted  with  these  charming 
little  troubadours  of  the  field,  we  should  have  a 
cricket  cage  with  a pair  of  them  within  it.  They  are 
most  companionable,  and  it  is  interesting  to  note  how 
quickly  they  respond  to  a musical  sound.  I had  a 
pair  in  my  room  at  one  time,  when  I lived  very  neai 
a cathedral.  Almost  every  time  that  the  bells  rang 
during  the  night,  my  cricket  would  respond  with  a 
most  vivacious  and  sympathetic  chirping. 

The  patent  leather  finish  to  this  cricket’s  clothes  is 
of  great  use;  for,  although  the  cricket  is  an  efficient 
jumper,  it  is  after  all,  mostly  by  running  between  grass  blades  that  it 
escapes  its  enemies.  If  we  try  to  catch  one,  we  realize  how  slippery  it  is, 
and  how  efficiently  it  is  thus  able  to  slide  through  the  fingers. 

The  haunts  of  the  cricket  are  usually  sunny;  it  digs  a little  cave 
beneath  a stone  or  clod  in  some  field,  where  it  can  have  the  whole  benefit 
of  all  the  sunshine,  when  it  issues  from  its  door,  These  crickets  cannot 
fly,  since  they  have  no  wings  under  their  wing-covers,  as  do  the  grass- 
hoppers. The  hind  legs  have  a strong  femur,  and  a short  but  strong  tibia 
with  downward  slanting  spines  along  the  hind  edge,  which  undoubtedly 
help  the  insect  in  scrambling  through  the  grass.  At  the  end  of  the  tibia, 
next  to  the  foot,  is  a rosette  of  five  spines,  the  two  longer  ones  slanting  to 

A section  of  the  file  enlarged .

meet  the  foot;  these  spines  give  the  insect  a firm  hold,  when  making 
ready  for  its  spring.  When  walking,  the  cricket  places  the  whole  hind 
foot  flat  on  the  ground,  but  rests  only  upon  the  claw  and  the  segment  next 
to  it,  of  the  front  pairs  of  feet.  The  claws  have  no  pads  like  those  of  the 
katydid  or  grasshopper;  the  segment  of  the  tarsus  next  the  claw  has  long 
spines  on  the  hind  feet  and  shorter  spines  on  the  middle  and  front  feet, 
thus  showing  that  the  feet  are  not  made  for  climbing,  but  for  scrambling 
along  the  ground.  When  getting  ready  to  jump,  the  cricket  crouches  so 
that  the  tibia  and  femur  of  the  hind  legs  are  shut  together  and  almost  on 
the  ground.  The  dynamics  of  the  cricket’s  leap  are  well  worth  studying, 


374 


Handbook  of  Nature-Study 


The  cricket’s  features  are  not  so  easily  made  out,  because  the  head  is 
polished  and  black;  the  eyes  are  not  so  polished  as  the  head,  and  the 
simple  eyes  are  present  but  are  discerned  with  difficulty.  The  antennas 
are  longer  than  the  body  and  very  active;  there  is  a globular  segment 
where  they  join  the  face.  I have  not  discovered  that  the  crickets  are  so 
fastidious  about  keeping  generally  clean  as  are  some  other  insects,  but 
they  are  always  cleaning  their  antennse  ; I have  seen  a cricket  play  his 
wing  mandolin  lustily  and  at  the  same  time  carefully  clean  his  antennas; 
he  polished  these  by  putting  up  a foot  and  bending  the  antenna  down  so 
that  his  mouth  reached  it  near  the  base;  he  then  pulled  the  antenna 
through  his  jaws  with  great  deliberation,  nibbling  it  clean  to  the  very  end. 
The  lens  reveals  to  us  that  the  flexibility  of  the  antenna;  is  due  to  the  fact 
that  they  are  many  jointed.  The  palpi  are  easily  seen,  a large  pair  above 
and  a smaller  pair  beneath  the  “chin.”  The  palpi  are  used  to  test  food 
and  prove  if  it  be  palatable.  The  crickets  are  fond  of  melon  or  other 
sweet,  juicy  fruits,  and  by  putting  such  food  into  the  cage  we  can  see  them 
bite  out  pieces  with  their  sidewise  working  jaws,  chewing  the  toothsome 
morsel  with  gusto.  They  take  hold  of  the  substance  they  are  eating  -with 
the  front  feet  as  if  to  make  sure  of  it. 

The  wing-covers  of  the  cricket  are  bent  down  at  the  sides  at  right 
angles,  like  a box  cover.  The  wing-covers  are  much  shorter  than  the 
abdomen  and  beneath  them  are  vestiges  of  wings,  which  are  never  used. 
The  male  has  larger  wing-covers  than  the  female,  and  they  are  veined  in  a 

peculiar  scroll  pattern.  This  veining 
seems  to  be  a framework  for  the  purpose 
of  making  a sounding  board  of  the  wing 
membrane,  by  stretching  it  out  as  a 
drum-head  is  stretched.  Near  the  base 
of  the  wing-cover,  there  is  a heavy  cross- 
vein covered  with  transverse  ridges, 
which  is  called  the  file;  on  the  inner 
edge  of  the  same  wing,  near  the  base,  is> 
a hardened  portion  called  the  scraper. 
When  he  makes  his  cry,  the  cricket  lifts 
his  wing-covers  at  an  angle  of  forty-five 
degrees  and  draws  the  scraper  of  the 
under  wing  against  the  file  of  the  over- 
lapping one;  lest  his  musical  apparatus 
become  worn  out,  he  can  change  by 
putting  the  other  wing-cover  above. 
The  wing-covers  are  excellent  sounding 
boards  and  they  quiver  as  the  note  is 
made,  setting  the  air  in  vibration,  and 
sending. the  sound  a long  distance.  The 
remale  cricket’s  wing-covers  are  more  normal  in  venation ; and  she  may 
always  be  distinguished  from  her  spouse  by  the  long  sword-like  ovipositor 
at  the  end  of  her  body;  this  she  thrusts  into  ^he  ground  when  she  lays 
he*  eggs,  thus  placing  them  where  they  will  remain  safely  protected 
during  the  winter.  Both  sexes  have  a pair  of  “tail  feathers,”  as  the 
children  call  them,  which  are  known  as  the  cerci  {sing,  cerca)  and  are 
fleshy  prongs  at  the  end  of  the  abdomen.

There  would  be  no  use  of  the  cricket’s  playing  his  mandolin  if  there 
were  not  an  appreciative  ear  to  listen  to  his  music.  This  ear  is  placed 
most  conveniently  in  the  tibia  of  the  front  leg,  so  that  the  crickets  literally 
hear  with  their  elbows,  as  do  the  katydids  and  the  meadow  grasshoppers. 
The  ear  is  easily  seen  with  the  naked  eye  as  a little  white,  disklike  spot. 

The  chirp  of  the  cricket  is,  in  literature,  usually  associated  with  the 
coming  of  autumn;  but  the  careful  listener  may  hear  it  in  early  summer, 
although  the  song  is  not  then  so  insistent  as  later  in  the  season.  He 
usually  commences  singing  in  the  afternoon  and  keeps  it  up  periodically 
all  night.  I have  always  been  an  admirer  of  the  manly,  dignified  methods 
of  this  little  “minnesinger,”  who  does  not  wander  abroad  to  seek  his  lady 
love  but  stands  sturdily  at  his  own  gate,  playing  his  mandolin  the  best  he 
is  able;  he  has  faith  that  his  sable  sweetheart  is  not  far  away,  and  that  if 
she  likes  his  song  she  will  come  to  him  of  her  own  free  will.  The  cricket  is 
ever  a lover  of  warmth  and  his  mandolin  gets  out  of  tune  soon  after  the 
evenings  become  frosty.  He  is  a jealous  musician.  When  he  hears  the 
note  of  a.  rival,  he  at  once  “bristles  up,”  lifting  his  wings  at  a higher  angle 
and  giving  off  a sharp  militant  note.  If  the  two  rivals  come  in  sight  of 
each  other,  there  is  a fierce  duel.  They  rush  at  each  other  with  wide  open 
jaws,  and  fight  until  one  is  conquered  and  retreats,  often  minus  an 
antenna,  cerca,  or  even  a leg.  The  cricket’s  note  has  a wide  range  of 
expression.  When  waiting  for  his  lady  love,  he  keeps  up  a constant 
droning;  if  he  hears  his  rival,  the  tone  is  sharp  and  defiant;  but  as  the 
object  of  his  affection  approaches,  the  music  changes  to  a seductive 
whispering,  even  having  in  it  an  uncertain  quiver,  as  if  his  feelings  were 
too  strong  for  utterance.

LESSON  LXXXII 
The  Black  Cricket 

Leading  thought — The  crickets  are  among  the 
most  famous  of  the  insect  musicians.  They  live  in 
the  fields  under  stones  and  in  burrows,  and  feed 
upon  grass  and  clover.  As  with  the  song  birds, 
the  male  only  makes  music;  he  has  his  wing- 
covers  developed  into  a mandolin  or  violin,  which 
he  plays  to  attract  his  mate  and  also  for  his  own 
pleasure. 

Method — Make  some  cricket  cages  as  follows : 
Take  a small  flower-pot  and  plant  in  it  a root  of 
fresh  grass  or  clover.  Place  over  this  and  press 
well  into  the  soil  a lantern  or  lamp  chimney. 
Cover  the  top  with  mosquito  netting.  Place  the 
pot  in  its  saucer,  so  that  it  may  be  watered  by 
keeping  the  saucer  filled.  Ask  the  pupils  to 
collect  some  crickets.  In  each  cage,  place  a male 
and  one  or  more  females,  the  latter  being  readily 
distinguished  by  the  long  ovipositors.  Place  the 
cages  in  a sunny  window,  where  the  pupils  may 


376 


Handbook  of  Nature-Study 


observe  them  at  recess,  and  ask  for  the  following  observations.  In 
studying  the  cricket  closely,  it  may  be  well  to  put  one  in  a vial  and  pass 
it  around.  In  observing  the  crickets  eat,  it  is  well  to  give  them  a 
piece  of  sweet  apple  or  melon  rind,  as  they  are  very  fond  of  pulpy  fruits. 

Observations — i.  Is  the  covering  of  the  cricket  shining,  like  black 
patent  leather,  or  is  it  dull?  What  portions  are  dull?  Of  what  use 
do  you  think  it  is  to  the  cricket  to  be  so  smoothly  polished? 

2.  Where  did  you  find  the  crickets?  When  you  tried  to  catch 
them,  how  did  they  act?  Did  they  fly  like  grasshoppers  or  did  they 
run  and  leap? 

3.  Look  carefully  at  the  cricket’s  legs.  Which  is  the  largest  of  the 
three  pairs?  Of  what  use  are  these  strong  legs?  Look  carefully  at 
the  tibia  of  the  hind  leg.  Can  you  see  the  strong  spines  at  the  end, 
just  behind  the  foot  or  tarsus?  Watch  the  cricket  jump  and  see  if 
you  can  discover  the  use  of  these  spines.  How  many  joints  in  the 
tarsus?  Has  the  cricket  a pad  like  the  grasshopper’s  between  its  claws? 
When  the  cricket  walks  or  jumps  does  it  walk  on  all  the  tarsus  of  each 
pair  of  legs? 

4.  Study  the  cricket’s  head.  Can  you  see  the  eyes?  Describe  the 
antennae — their  color,  length,  and  the  way  they  are  used.  Watch  the 
cricket  clean  its  antennae  and  describe  the  process.  Can  you  see  the  little 
feelers,  or  palpi,  connected  with  the  mouth?  How  many  are  there? 
How  does  it  use  these  feelers  in  tasting  food  before  it  eats?  Watch  the 
cricket  eat,  and  see  whether  you  can  tell  whether  its  mouth  is  made  for 
biting  or  sucking. 

5.  Study  the  wings..  Are  the  wings  of  the  mother  cricket  the  same 
size  and  shape  as  those  of  her  mate?  How  do  they  differ?  Does  the 
cricket  have  any  wings  under  these  front  wings,  as  the  grasshopper  does? 
Note  the  cricket  when  he  is  playing  his  wing  mandolin  to  attract  his 
mate.  How  does  he  make  the  noise?  Can  you  see  the  wings  vibrate? 
Ask  your  teacher  to  show  you  a picture  of  the  musical  wings  of  the 
cricket,  or  to  show  you  the  wings  themselves  under  the  microscope,  so 
that  you  may  see  how  the  music  is  made. 

6.  Why  does  the  mother  cricket  need  such  a long  ovipositor?  Where 
does  she  put  her  eggs  in  the  fall  to  keep  them  safe  until  spring? 

7.  Look  in  the  tibia,  or  elbow,  of  the  front  leg  for  a little  white  spot. 
What  do  you  suppose  this  is?  Are  there  any  white  spots  like  it  on  the 
other  legs  ? Ask  your  teacher  to  tell  you  what  this  is. 

8.  Can  you  find  the  homes  of  the  crickets  in  the  fields?  Do  the  black 
crickets  chirp  in  the  day-time  or  after  dark?  Do  they  chirp  in  cold  or 
windy  weather,  or  only  when  the  sun  shines?

THE  SNOWY  TREE-CRICKET 


Teacher's  Story 

HIS  is  a slim,  ghost-like  cricket.  It  is  pale  green, 
almost  white  in  color,  and  about  three-fourths  of  an 
inch  long.  Its  long,  slender  hind  legs  show  that  it  is 
a good  jumper.  Its  long  antennas,  living  threads, 
pale  gray  in  color,  join  the  head  with  amber  globe-like 
segments.  The  pale  eyes  have  a darker  center  and 
the  palpi  are  very  long.  The  male  has  the  wing- 
covers  shaped  and  veined  like  those  of  the  black 
cricket,  but  they  are  not  so  broad  and  are  whitish  and 
very  delicate.  The  wings  beneath  are  wide,  for  these 
crickets  can  fly.  The  female  has  a long,  sword-like  ovipositor. 

The  snowy  tree-cricket,  like  its  relatives,  spends  much  time  at  its 
toilet.  It  whips  the  front  foot  over  an  antenna  and  brings  the  base  of  the 
latter  to  the  mandibles  with  the  palpi  and  then  cleans  it  carefully  to  the 
very  tip.  It  washes  its  face  with  the  front  foot,  always  with  a downward 
movement.  If  the  hind  foot  becomes  entangled  in  anything  it  first  tries 
to  kick  it  clean,  and  then  drawing  it  beneath  the  body,  bends  the  head  so 
as  to  reach  it  with  the  mandibles  and  nibbles  it  clean.  The  middle  foot 
it  also  thrusts  beneath  the  body,  bringing  it  forward 
between  the  front  legs  for  cleaning.  But  when 
cleaning  its  front  feet,  the  snowy  tree-cricket  puts  on 
airs;  it  lifts  the  elbow  high  and  draws  the  foot 
through  the  mouth  with  a gesture  very  like  that  of  a 
young  lady  with  a seal  ring  on  her  little  finger,  hold- 
ing the  ornate  member  out  from  its  companions  as  if 
it  were  stiff  with  a consciousness  of  its  own  import- 
ance. 

There  are  two  common  species  of  the  snowy  tree- 
crickets  which  can  hardly  be  separated  except  by 
specialists  or  by  watching  their  habits.  One  is 
called  “the  whistler’’  and  lives  on  low  shrubs  or 
grass;  it  gives  a clear,  soft,  prolonged,  unbroken 
note.  The  other  is  called  “the  fiddler”  and  lives  on 
shrubs  and  in  trees  and  vines.  Its  note  is  a pianis- 
simo performance  of  the  katydid’s  song;  it  is  delight- 
ful, rhythmic  and  sleep-inspiring ; it  begins  in  the  late 
afternoon  and  continues  all  night  until  the  early, 
cold  hours  of  the  approaching  dawn.  The  vivacity 
of  the  music  depends  upon  the  temperature,  as  the 
notes  are  given  much  more  rapidly  during  the  hot 
nights. 

“So  far  as  we  know,  this  snowy  tree-cricket  is  the 
only  one  of  the  insect  musicians  that  seems  conscious 
of  the  fact  that  he  belongs  to  an  orchestra.  If  you  tree*

THE  COCKROACH 
Teacher's  Story 

OCKROACHES  in  our  kitchens  are  undoubtedly  an 
unmitigated  nuisance,  and  yet,  as  in  many  other  in- 
stances. when  we  come  to  consider  the  individual 
cockroach,  we  find  him  an  interesting  fellow  and 
exceedingly  well  adapted  for  living  in  our  kitchens 
despite  us. 

In  shape,  the  cockroach  is  flat,  and  is  thus  well 
adapted  to  slide  beneath  utensils  and  into  crevices 
and  corners.  Its  covering  is  smooth  and  polished 
like  patent  leather,  and  this  makes  it  slippery  and 
enables  it  to  get  into  food  without  becoming  clogged 
by  the  adherence  of  any  sticky  substance.  The 
antennas  are  very  long  and  flexible  and  can  be  bent  in  any  direction. 
They  may  be  placed  far  forward  to  touch  things  which  the 
insert  is  approaching,  or  may  be  placed  over  the  back  in  order 
to  be  out  of  the  way.  They  are  like  graceful,  living  threads, 
and  the  cockroach  tests  its  whole  environment  with  their  aid. 

The  mouth  has  two  pairs  of  palpi  or  feelers,  one  of  which  is 
very  long  and  noticeable  ; these  are  kept- in  constant  motion 
as  if  to  test  the  appetizing  qualities  of  food.  The  mouth-parts 
are  provided  with  jaws  for  biting  and,  like  all  insect  jaws,  these 
work  sidewise  instead  of  up  and  down.  The  eyes  are  black 
but  not  prominent  or  large,  and  seem  to  be  merely  a part  of 
the  sleek,  polished  head-covering. 

Some  species  of  cockroaches  have  wings,  and  some  do  not. 

Those  which  have  wings,  have  the  upper  pair  thickened  and  used  for  wing-

covers.  The  under  pair  are  thinner  and  are  laid  in  plaits  like  a fan.  The 
wing-covers  are  as  polished  as  the  body  and  quite  as  successful  in  shedding 
dirt. 

The  legs  are  armed  with  long  spines  which  are  very  noticeable  and 
might  prove  to  be  a disadvantage  in  accumulating  filth;  but  they  are 
polished  also;  and  too,  this  insect  spends  much  time  at  its  toilet. 

Cockroaches  run  “like  a streak”,  children  say;  so  speedily,  indeed,  do 
they  go  that  they  escape  our  notice,  although  we  may  be  looking  directly 
at  them.  This  celerity  in  vanishing,  saves  many  a cockroach  from  being 
crushed  by  an  avenging  foot. 


When  making  its  toilet,  the  cockroach 
draws  its  long  antenna  through  its  jaws  as 
if  it  were  a whiplash,  beginning  at  the  base 
and  finishing  at  the  tip.  It  cleans  each  leg 
by  beginning  near  the  body  and  so  stroking 
downward  the  long  spines  which  seem  to  shut 
against  the  leg.  It  nibbles  its  feet  clean  to 
the  very  claws,  and 
scrubs  its  head  vigor-

The  cockroach’s 

eggs  are  laid  in  a mass  enclosed  in  a pod- 
shaped covering,  which  is  waterproof  and 
polished  and  protects  its  contents  from  damp- 
ness. "When  the  cockroaches,  or  the  croton 
bugs,  as  the  small  introduced  species  of  coek- 
Cockroach  laying  her  case  roach  is  called,  once  become  established  in  a 

°f  eggs-  house,  the  only  way  to  get  rid  of  them  is  to

which  is  a dangerous  performance  and  should  be  done  only  by  an  expert. 


LESSON  LXXXIII 
The  Cockroach 

Leading  thought — The  cockroach  is  adapted  for  living  in  crevices,  and 
although  its  haunts  may  be  anything  but  clean,  the  cockroach  keeps  itself 
quite  clean.  The  American  species  live  in  fields  and  woods  and  under 
stones  and  sticks  and  only  occasionally  venture  into  dwellings.  The 
species  that  infest  our  kitchens  and  water-pipes  are  European. 

Method — Place  a cockroach  in  a vial  with  bread,  potato  or  some  other 
food,  cork  the  vial,  and  pass  it  around  so  that  the  children  may  observe 
the  prisoner  at  their  leisure. 

Observations — i.  W7hat  is  the  general  shape  of  the  cockroach?  Why 
is  this  an  advantage?  What  is  the  texture  of  its  covering?  Why  is  this 
an  advantage  ? 

2.  Describe  the  antennas  and  the  way  they  are  used.  Note  the  two 
little  pairs  of  feelers  at  the  mouth.  If  possible,  see  how  they  are  used 
when  the  cockroach  is  inspecting  something  to  eat.  Can  you  see  whether 
its  mouth  is  fitted  for  biting,  lapping  or  sucking  its  food  ? 


380  Handbook  of  N ature-Stuay 

3.  Note  the  eyes.  Are  they  as  large  and  prominent  as  those  of  the 
bees  or  butterflies? 

4.  Has  this  cockroach  wings?  If  so,  how  many  and  what  are  they 
like?  Note  two  little  organs  at  the  end  of  the  body?  These  are  the 
cerci,  like  those  of  the  crickets. 

5.  Describe  the  general  appearance  of  the  cockroach’s  legs,  and  tell 
what  you  think  about  its  ability  as  a runner. 

6.  Note  how  the  cockroach  cleans  itself  and  how  completely  and  care- 
fully this  act  is  performed.  Have  you  ever  seen  cockroach’s  eggs?  If  so, 
describe  them. 

7.  How  can  you  get  rid  of  cockroaches  if  they  invade  your  kitchen? 


LESSON  LXXXIV 
How  to  Make  an  Aquarium 

HE  schoolroom  aquarium  may  be  a very  simple 
affair  and  still  be  effective.  Almost  any  glass 
receptacle  will  do,  glass  being  chosen  because  of 
its  transparency,  so  that  the  life  within  may  be 
observed.  Tumblers,  jelly  tumblers,  fruit  jars, 
butter  jars,  candy  jars  and  battery  jars  are  all 
available  for  aquaria.  The  tumblers  are  especially 
recommended  for  observing  the  habits  of  aquatic 
insects. 


To  make  an  aquarium:  1.  Place  in  the  jar  a layer  of  sand  an  inch 

or  more  in  depth. 

2.  In  this  sand  plant  the  water  plants  which  you  find  growing  under 
water  in  a pond  or  stream;  the  plants  most  available  are  Water-weed, 
Bladderwort,  Water  Starwort,  Watercress,  Stoneworts,  Frog-spittle  or 
Water-silk. 

3.  Place  on  top  a layer  of  small  stones  or  gravel;  this  is  to  hold  the 
plants  in  place. 

4.  Tip  the  jar  a little  and  pour  in  very  gentl / at  one  side  water  taken 
from  a pond  or  stream.  Fill  the  jar  to  within  two  or  three  inches  of 
the  top;  if  it  be  a jelly  tumbler,  fill  to  within  an  inch  of  the  top. 

5.  Let  it  settle. 

6.  Place  it  in  a window  which  does  not  get  too  direct  sunlight.  A 
north  window  is  the  best  place ; if  there  is  no  north  window  to  the  school 
room,  place  it  far  enough  at  one  side  of  some  other  window  so  that  it  will 
not  receive  too  much  sunlight. 

7.  To  get  living  creatures  for  the  aquarium  use  a dip-net,  which  is 
made  like  a shadow,  insect  net. 

8.  Dip  deep  into  the  edges  of  the  pond  and  be  sure  to  bring  up  some 
of  the  leaves  and  mud,  for  it  is  in  these  that  the  little  vater  animals  live. 

9.  As  fast  as  dipped  up,  these  should  be  placed  in  a pail  of  water,  so 
that  they  may  be  carried  to  the  schoolroom. 

10.  In  introducing  the  water  animals  into  the  aquarium  ;t  is  well  to 
put  but  a few  in  each  jar. 

The  care  of  the  aquarium — Care  should  be  taken  to  preserve  the  plant 
life  in  the  aquarium,  as  the  plants  are  necessary  to  the  life  of  the  animals. 
They  not  only  supply  the  food,  but  they  give  off  oxygen  which  the  animals 


Insect  Study  381 

need  for  breathing,  and  they  also  take  up  from  the  water  the  poisonous 
carbonic  acid  gas  given  off  from  the  bodies  of  the  animals. 

1.  The  aquarium  should  be  kept  where  there  is  a free  circulation  of 

air. 

2.  If  necessary  to  cover  the  aquarium  to  prevent  the  insects,  like  the 
water  boatmen  and  water  beetles,  from  escaping,  tie  over  it  a bit  of  mos- 
quito netting,  or  lay  upon  the  top  a little  square  of  wire  netting  used  for 
window  screens. 

3.  The  temperature  should  be  kept  rather  cool;  it  is  better  that  the 
water  of  the  aquarium  should  not  be  warmer  than  50  deg.  Fahrenheit,  but 
this  is  not  always  possible  in  the  schoolroom. 

4.  If  any  insects  or  animals  die  in  the  aquarium  they  should  be 
removed  at  once,  as  the  decomposing  bodies  render  the  water  foul. 

5.  To  feed  the  animals  that  live  upon  other  animals  take  a bit  of  raw 
beef,  tie  a string  to  it  and  drop  it  in,  leaving  the  free  end  of  the  string 
outside  of  the  jar.  After  it  has  been  in  one  day,  pull  it  out;  for  if  it 
remains  longer  it  will  make  the  water  foul. 

6.  As  the  water  evaporates  it  should  be  replaced  with  water  from  the 
pond.

THE  DRAGON-FLIES  AND  DAMSEL-FLIES 
Teacher's  Story 

POND  without  dragon-flies  darting  above  it,  or  without  the  ex- 
quisitely iridescent  damsel-flies  clinging  to  the  leaves 
of  its  border  would  be  a lonely  place  indeed.  As  one 
watches  these  beautiful  insects,  one  wonders  at  the 
absurd  errors  which  have  crept  into  popular  credence 
about  them.  Who  could  be  so  silly  as  to  believe 
that  they  could  sew  up  ears  or  that  they  could  bring 
dead  snakes  to  life!  The  queer  names  of  these  in- 
sects illustrate  the  prejudices  of  the  ignorant — devil’s 
darning  needles,  snake  doctors,  snake  feeders,  etc. 
Despite  all  this  slander,  the  dragon-flies  remain  not 
only  entirely  harmless  to  man,  but  in  reality  are  his 
friends  and  allies  in  waging  war  against  flies  and 
mosquitoes;  they  are  especially  valuable  in  battling  mosquitoes  since 
the  nymphs,  or  young,  of  the  dragon-fly,  take  the  wrigglers  in  the 
water,  and  the  adults,  on  swiftest  wings,  take  the  mosquitoes  while 
hovering  over  ponds  laying  their  eggs. 


The  ten-spot. 

From  Outdoor  Studies,  Needham. 

The  poets  have  been  lavish  in  their  attention  to  these  interesting 
insects  and  have  paid  them  delightful  tributes.  Riley  says: 

“ Till  the  dragon  fly , in  light  gauzy  armor  burnished  bright , 

Came  tilting  down  the  waters  in  a wild,  bewildered  flight .” 

While  Tennyson  drew  inspiration  for;  one  of  his  most  beautiful  poems 
from  the  two  stages  of  dragon-fly  life.  But  perhaps  Lowell  in  that 
exquisite  poem,  “The  Fountain  of  Youth,”  gives  us  the  perfect  descrip- 
tion of  these  insects: 


In  summer-noon  flushes 
When  all  the  wood  hushes , 
Blue  dragon-flies  knitting 
To  and  fro  in  the  sun, 
With  sidelong  jerk  flitting. 
Sink  down  on  the  rushes. 


And,  motionless  sitting, 

Hear  it  bubble  and  run, 
Hear  its  low  inward  singing 
With  ' level  wings  swinging 
On  green  tasselled  rushes , 

To  dream  in  the  sun. 


Insect  Study 


383 


It  is  while  we,  ourseives,  are  dreaming  m the  sun  by  the  margin  of 
some  pond,  that  these  swift  children  of  the  air  seem  but  a natural  part 
of  the  dream.  Yet  if  we 
waken  to  note  them  more 
closely,  we  find  many  things 
very  real  to  interest  us. 

First,  they  are  truly  children 
of  the  sun,  and  if  some  cloud 
throws  its  shadow  on  the 
waters  for  some  moments, 
the  dragon-flies  disappear  as 
if  they  wore  the  invisible 
cloak  of  the  fairy  tale. 

Only  a few  of  the  common 
species  fly  alike  in  shade  and 
sunshine,  and  early  and  late. 

The  best  known  of  these  is 


A common  dragon-fly. 

Comstock’s  Manual. 


the  big,  green  skimmer,  which  does  not  care  so  much  for  ponds,  but 
darts  over  fields  and  even  dashes  into  our  houses,  now  and  then. 
Probably  it  is  this  species  which  has  started  all  of  the  dragon-fly 
slander,  for  it  is  full  of  curiosity,  and  will  hold  itself  on  wings  whirring  too 
rapidly  to  even  make  a blur,  while  it  examines  our  faces  or  inspects  the 
pictures  or  furniture  or  other  objects  which  attract  it. 

Another  thing  we  may  note  when  dreaming  by 
the  pond  is  that  the  larger  species  of  dragon-flies 
keep  to  the  higher  regions  above  the  water,  while 
the  smaller  species  and  the  damsel-flies  flit  near  its 
surface.  Well  may  the  smaller  species  keep  below 
their  fierce  kindred,  otherwise  they  would  surely 
be  utilized  to  sate  their  hunger,  for  these  insects  are 
well  named  dragons,  and  dragons  do  not  stop  to 
inquire  whether  their  victims  are  relatives  or  not. 
It  is  when  they  are  resting,  that  the  dragon  and 
damsel-flies  reveal  their  most  noticeable  differences. 
The  dragon-fly  extends  both  wings  as  if  in  flight 
while  it  basks  in  the  sun  or  rests  in  the  shadow. 
There  is  a big,  white-bodied  species  called  the 
whitetail  which  slants  its  wings  forward  and  down 
when  it  rests;  but  the  damsel-flies  fold  their  wings 
together  over  the  back  when  resting.  The  damsel- 
flies  have  more  brilliantly  colored  bodies  than  do 
the  dragon-flies,  many  of  them  being  iridescent 
green  or  coppery;  they  are  more  slender  and 
delicate  in  form.  The  damsel-fly  has  eyes  which 
are  so  placed  on  the  sides  of  the  head  as  to  make 
it  look  like  a cross  on  the  front  of  the  body  fastened 
to  the  slender  neck,  and  with  an  eye  at  the  tip  of 
each  arm.  There  are  very  many  species  of  dragon 
and  damsel-flies,  but  they  all  have  the  same  general  habits. 

The  dragon-fly  nymphs  are  the  ogres  of  the  pond  or  stream.  To  any- 
one unused  to  them  and  their  ways  in  the  aquarium,  there  is  a surprise 
in  store,  so  ferocious  are  they  in  their  attacks  upon  creatures  twice

their  size.  The  dragon-fly’s  eggs  are  laid  in  the  water;  in  some 
instances  they  are  simply  dropped  and  sink 
to  the  bottom ; but  in  the  case  of  damsel-flies,  the 
mother  punctures  the  stems  of  aquatic  plants  and 
places  the  eggs  within  them.  The  nymph  in  no 
wise  resembles  the  parent  dragon-fly.  It  is  a 
dingy  little  creature,  with  six  queer,  spider-like 
legs  and  no  wings;  although  there  are  four  little 
wing-pads  extending  down  its  back,  which  encase 
the  growing  wings.  It  may  remain  hidden  in  the 
rubbish  at  the  bottom  of  the  pond  or  may  cling 
to  water  weeds  at  the  sides,  for  different  species 
have  different  habits.  But  in  them  all  we  find  a 
most  amazing  lower  lip.  This  is  so  large  that  it 
covers  the  lower  part  of  the  face  like  a mask,  and 
when  folded  back  reaches  down  between  the  front 
legs.  It  is  in  reality  a grappling  organ  with  hooks 
and  spines  for  holding  prey;  it  is  hinged  in  such  a 
manner  that  it  can  be  thrust  out  far  beyond  the 
head  to  seize  some  insect,  unsuspecting  of  danger. 
These  nymphs  move  so  slowly  and  look  so  much 
like  their  background,  that  they  are  always 
practically  in  ambush  awaiting  their  victims. 

The  breathing  of  the  dragon-fly  nymphs  is  peculiar;  there  is  an 
enlargement  of  the  rear  end  of  the  alimentary  canal,  in  the  walls  of  which 
tracheae  or  breathing  tubes  extend  in  all  directions.  The  nymph  draws 
water  into  this  cavity  and  then  expels  it,  thus  bathing  the  tracheae  with 
the  air  mixed  with  water  and  purifying  the  air  within  them.  Expelling 
the  water  so  forcibly,  propels  the  nymph  ahead,  so  this  act  serves  as  a 
method  of  swimming  as  well  as  of  breath- 
ing. Damsel-fly  nymphs,  on  the  other 
hand,  have  at  the  rear  end  of  the  body, 
three  long,  plate-like  gills,  each  ramified 
with  tracheae. 

Nymphs  grow  by  shedding  the  skin 
as  fast  as  it  becomes  too  small ; and  when 
finally  ready  to  emerge,  they  crawl  up  on 
some  object  out  of  the  water,  and  molt  for 
the  last  time,  and  are  thereafter  swift 
creatures  of  the  air.

LESSON  LXXXV 

The  Dragon-flies  and  Damsel-flies 

Leading  thought — The  dragon-flies  are  among  the  swiftest  of  all  winged 
creatures  and  their  rapid,  darting  flight  enables  them  to  hawk  their  prey, 
which  consists  of  other  flying  insects.  Their  first  stages  are  passed  in  the 
bottoms  of  ponds  where  they  feed  voraciously  on  aquatic  creatures.  The 
dragon-flies  are  beneficial  to  us  because,  when  very  young  and  when  full 
grown,  they  feed  largely  upon  mosquitoes. 


Insect  Study

Outdoor  Studies,  Needham. 


Method — The  work  of  observing  the  habits  of  adult  dragon-flies  should 
be  largely  done  in  the  field  during  late  summer  and  early  autumn.  The 
points  for  observation  should  be  given  the  pupils  for  summer  vacation 
use,  and  the  results  placed  in  the  field  note-book. 

The  nymphs  may  be  studied  in  the  spring,  when  getting  material  for 
the  aquarium.  April  and  May  are  the  best  months  for  securing  them. 
They  are  collected  by  using  a dip-net,  and  are  found  in  the  bottoms  of 
reedy  ponds  or  along  the  edges  of  slow-flowing  streams.  These  nymphs 
are  so  voracious  that  they  cannot  be  trusted  in  the  aquarium  with  other 
insects ; each  must  be  kept  by  itself.  They  may  be  fed  by  placing  other 
water  insects  in  the  aquarium  with  them 
or  by  giving  them  pieces  of  fresh  meat. 

In  the  latter  case,  tie  the  meat  to  a 
thread  so  that  it  may  be  removed  after 
a few  hours,  if  not  eaten,  since  it  soon 
renders  the  water  foul. 

The  dragon-fly  aquarium  should  have 
sand  at  the  bottom  and  some  water 
weeds  planted  in  it,  and  there  should  be 
some  object  in  it  which  extends  above 
the  surface  of  the  water  which  the 
nymphs,  when  ready  to  change  to  adults, 
can  climb  upon  while  they  are  shedding  the 
last  nymphal  skin,  and  spreading  their 
new  wings. 

Observations  on  the  young  of  dragon- 
flies— 1.  Where  did  you  find  these  in- 
sects? Were  they  at  the  bottom  of  the 
pond  or  along  the  edges  among  the  water 
weeds? 

2 . Are  there  any  plume-like  gills  at  the 
end  of  the  body?  If  so,  how  many?  Are 
these  plate-like  gills  used  for  swimming? 

If  there  are  three  of  these,  which  is  the 
longer?  Do  you  know  whether  the 
nymphs  with  these  long  gills  develop  into 
dragon  or  into  damsel-flies? 

3.  If  there  are  no  plume-like  gills  at 
the  end  of  the  body,  how  do  the  insects  move?  Can  they  swim?  What 
is  the  general  color  of  the  body?  Explain  how  this  color  protects  them 
from  observation?  What  enemies  does  it  protect  them  from? 

4.  Are  the  eyes  large  ? Can  you  see  the  little  wing-pads  on  the  back 
in  which  the  wings  are  developing?  Are  the  antennae  long? 

5.  Observe  how  the  nymphs  of  both  dragon  and  damsel-flies  seize 
their  prey.  Describe  the  great  lower  lip  when  extended  for  prey.  How 
does  it  look  when  folded  up  ? 

6.  Can  you  see  how  a nymph  without  the  plume-like  gills  breathes? 
Notice  if  the  water  is  drawn  into  the  rear  end  of  the  body  and  then 
expelled.  Does  this  process  help  the  insect  in  swimming? 

7.  When  the  dragon  or  damsel-fly  nymph  has  reached  its  full  growth, 
where  does  it  go  to  change  to  the  winged  form?  How  does  this  change 
take  place?  Look  on  the  rushes  and  reeds  along  the  pond  margin,  and  see

Observations  on  the  adult  dragon-flies — i.  Catch  a dragon-fly,  place 
it  under  a tumbler  and  see  how  it  is  fitted  for  life  in  the  air.  Which  is  the 
widest  part  of  its  body?  Note  the  size  of  the  eyes  compared  with  the 
remainder  of  the  head.  Do  they  almost  meet  at  the  top  of  the  head? 
How  far  do  they  extend  down  the  sides  of  the  head?  Why  does  the 
dragon-fly  need  such  large  eyes?  Why  does  a creature  with  such  eyes 
not  need  long  antennae?  Can  you  see  the  dragon-fly’s  antennae?  Look 
with  a lens  at  the  little,  swollen  triangle  between  the  place  where  the  two 
eyes  join  and  the  forehead;  can  you  see  the  little,  simple  eyes?  Can  you 
see  the  mouth-parts? 

2.  Next  to  the  head,  which  is  the  widest  and  strongest  part  of  the 
body?  Why  does  the  thorax  need  to  be  so  big  and  strong?  Study  the 
wings.  How  do  the  hind  wings  differ  in  shape  from  the  front  wings? 
How  is  the  thin  membrane  of  the  wings  made  strong?  Are  the  wings 
spotted  or  colored?  If  so,  how?  Can  you  see  if  the  wings  are  folded 
along  the  front  edges?  Does  this  give  strength  to  the  part  of  the  wing 
which  cuts  the  air?  Take  a piece  of  writing  paper  and  see  how  easily  it 
bends ; fold  it  two  or  three  times  like  a fan  and  note  how  much  stiff er  it 
is.  Is  it  this  principle  which  strengthens  the  dragon-fly’s  wings?  Why 
do  these  wings  need  to  be  strong? 

3 . Is  the  dragon-fly’s  abdomen  as  wide  as  the  front  part  of  the  body? 
What  help  is  it  to  the  insect  when  flying  to  have  such  a long  abdomen? 

Outline  for  field  notes — Go  to  a pond  or  sluggish  stream  when  the  sun 
is  shining,  preferably  at  midday,  and  note  as  far  as  possible  the  following 
things : 

1.  Do  you  see  dragon-flies  darting  over  the  pond?  Describe  their 
flight.  They  are  hunting  flies  and  mosquitoes  and  other  insects  on  the 
wing;  note  how  they  do  it.  If  the  sky  becomes  cloudy,  can  you  see  the 
dragon-flies  hunting?  In  looking  over  a pond  where  there  are  many 
dragon-flies  darting  about,  do  the  larger  species  fly  higher  than  the 
smaller  ones  ? 

2.  Note  the  way  the  dragon-flies  hold  their  wings  when  they  are 
resting.  Do  they  rest  with  their  wings  folded  together  over  the  abdomen 
or  are  they  extended  out  at  an  angle  to  the  abdomen  ? Do  you  know  how 
this  difference  in  attitude  of  resting  determines  one  difference  between  the 
damsel-flies  and  the  dragon-flies? 

3 . The  damsel-flies  are  those  which  hold  their  wings  folded  above  the 
back  when  resting.  Are  these  as  large  and  strong-bodied  as  the  dragon- 
flies? Are  their  bodies  more  brilliantly  colored?  How  does  the  shape  of 
the  head  and  eyes  differ  from  those  of  the  dragon-flies?  How  many 
different  colored  damsel-flies  can  you  find? 

4.  Do  you  see  some  dragon-flies  dipping  down  in  the  water  as  they 
fly?  If  so,  they  are  laying  their  eggs.  Note  if  you  find  others  clinging  to 
reeds  or  other  plants  with  the  abdomen  thrust  below  the  surface  of  the 
water.  If  so,  these  are  inserting  their  eggs  into  the  stem  of  the  plant.

THE  CADDIS-WORMS  AND  THE  CADDIS-FLIES 


Teacher's  Story 

EOPLE  are  to  be  pitied  who  have  never  tried  to  fathom 
the  mysteries  of  the  bottom  of  brook  or  pond.  Just  to 
lie  flat,  face  downward,  and  watch  for  a time  all  that 
happens  down  there  in  that  water  world,  is  far  more 
interesting  than  witnessing  any  play  ever  given  at 
matinee.  At  first  one  sees  nothing,  since  all  the  swift- 
moving  creatures  have  whisked  out  of  sight,  because 
they  have  learned  to  be  shy  of  moving  shadows;  but 
soon  the  crayfish  thrusts  out  his  boxing  gloves  ±rom 
some  crevice,  then  a school  of  tiny  minnows  “stay 
their  wavy  bodies  ‘gainst  the  stream;”  and  then 
something  strange  happens ! A bit  of  rubbish  on  the  bottom  of  the  brook 
walks  off.  Perhaps  it  is  a dream,  or  we  are  under  the  enchantment  of  the 
water  witches!  But  no,  there  goes  another,  and  now  a little  bundle  ot 
sand  and  pebbles  takes  unto  itself  legs.  These  mysteries  can  only  be 
solved  with  a dip-net  and  a pail  half  filled  with  water,  in  which  we 
may  carry  home  the  treasure  trove. 

When  we  finally  lodge  our  catch  in  the  aquarium  jar,  our  mysterious 
moving  sticks  and  stones  resolve  themselves  into  little  houses  built  in 
various  fashions,  and  each  containing  one  inmate.  Some  of  the  houses 
are  made  of  sticks  fastened  together  lengthwise ; some  are  built  like 
log  cabins,  crosswise ; some  consist  simply  of  a hollow  stem  cut  a con- 
venient length ; and  some  are 
made  of  sand  and  pebbles, 
and  one,  the  liveliest  of  all,  is 
a little  tube  made  of  bits  of 
rubbish  and  silk  spun  in  a spir- 
al, making  a little  cornucopia. 

On  the  whole,  the  species 
which  live  in  the  log  cabins 
are  the  most  convenient  to 
study.  Whatever  the  shape 
of  the  case  or  house,  it  has  a 
very  tough  lining  of  silk,  which 
is  smooth  within,  and  forms 
the  framework  to  which  the 
sticks  and  stones  are  fastened. 

These  little  dwellings  always 
have  a front  door  and  a back 
door.  Out  of  the  front  door 
may  protrude  the  dark-col- 
ored head  followed  by  two 
dark  segments  and  six  per- 
fectly active  legs,  the  front 
pair  being  so  much  shorter 
than  the  other  two  pairs  that 

they  look  almost  like  mouth  Tog  cabin  caddis-worms  in  their  cases  feeding 
palpi.  In  time  of  utter  peace,  upon  a water  plant.

is  thrust  out  and  we  see  the  hind  segment  of  the  thorax  which  is 
whitish,  and  behind  this  the  abdomen  of  nine  segments.  At  the  sides 

of  the  abdomen,  and  apparently  be- 
tween the  segments,  are  little  tassels 
of  short,  white  thread-like  gills. 
These  are  filled  with  air,  impure  from 
contact  with  the  blood,  and  which  ex- 
changes its  impurities  speedily  for  the 
oxygen  from  the  air  which  is  mixed 
flowing  in  at  the  front  door  of  the 
cabin,  over  the  gills  and  out  at  the  back  door,  by  the  rhythmic  movement 
of  the  body  of  the  little  hermit,  and  thus  a supply  of  oxygen  is  steadily 
maintained. 

The  caddis-worm  is  not  grown  fast  to  its  case  as  is  the  snail 
to  its  shell.  If  we  hold  down  with  forceps  a case  in  which  the 
occupant  is  wrong  side  up,  after  a few  struggles  to  turn  itself  over,  case 
and  all,  it  will  turn  over  within  the  case.  It  keeps  its  hold  upon  the  case 
by  two  forward-curving  hooks,  one  on  each  side  of  the  tip  of  the  rear 
segment.  These  hooks  are  inserted  in  the  tough 
silk  and  hold  fast.  It  also  has  on  top  of  the  first 
segment  of  the  abdomen  a tubercle,  which  may  be 
extended  at  will ; this  helps  to  brace  the  larva  in  its 
stronghold,  and  also  permits  the  water  to  flow  freely 
around  the  insect.  So  the  little  hermit  is  en- 
trenched in  its  cell  at  both  ends.  When  the  log- 
cabin  species  wishes  to  swim,  it  pushes  almost  its 
entire  body  out  of  the  case,  thrusts  back  the  head, 
spreads  the  legs  wide  apart,  and  then  doubles  up,  thus  moving  through 
the  water  spasmodically,  -in  a manner  that  reminds  us  of  the  crayfish’s 
swimming  except  that  the  caddis-worm  goes  head  first.  This  log  cabin 
species  can  turn  its  case  over  dexterously  by  movements  of  its  legs. 

The  front  legs  of  the  caddis-worm  are  so  much  shorter  than  the  other 
two  pairs  that  they  look  like  palpi,  and  their  use  is  to  hold  close  to  the 
jaws  bits  of  food,  which  are  being  eaten.  The  other  legs  are  used  for  this 
too  if  the  little  legs  cannot  manage  it ; perhaps  also  these  short  front  legs 
help  hold  the  bits  of  building  material  in  place  while  the  web  is  woven  to 
hold  it  there.  The  caddis-worm,  like  the  true  caterpillars,  has  the  open- 
ing of  the  silk  gland  near  the  lower  lip.  The  food  of  most  caddis-worms 

is  vegetable,  usually  the  various 
species  of  water  plants ; but  there  are 
some  species  which  are  carnivorous, 
like  the  net-builder,  which  is  a fisher- 
man. 

The  caddis-worm  case  protects  its 
inmate  in  two  ways:  First,  from  the 

sight  of  the  enemy,  and  second,  from 
its  jaws.  A fish  comes  along  and  sees 
a nice  white  worm  and  darts  after  it, 
only  to  find  a bundle  of  unappetizing 
sticks  where  the  worm  was.  All  of 
the  hungry  predatory  creatures  of  the 
pond  and  stream  would  be  glad  to

get  the  caddis-worm,  if  they  knew 
where  it  went.  Sometimes  caddis- 
worm  cases  have  been  found  in  the 
stomachs  of  fishes ; perhaps  they 
serve  as  fish  breakfast-food. 

While  it  is  difficult  to  see  the 
exact  operation  of  building  the 
caddis-worm  house,  the  general 
proceeding  may  be  readily  observed. 

Take  a vigorous  half -grown  larva, 
tear  off  part  of  the  sticks  and  bits  of 
leaves  that  make  the  log  cabin,  and 
then  place  the  little  builder  in  a tumbler  with  half  an  inch  of  water  at  the 
bottom,  in  which  are  many  bright  flower  petals  cut  into  strips,  fit  for 
caddis  lumber.  In  a few  hours  the  little  house  will  look  like  a blossom 
with  several  rows  of  bright  petals  set  around  its  doorway. 

When  the  caddis- worm  gets  ready  to  pupate,  it  fastens  its  case  to  some 

object  in  the  water  and  then  closes 
its  front  and  back  doors.  Different 
species  accomplish  this  in  different 
ways ; some  spin  and  fasten  a 
silken  covering  over  the  doors ; 
often  this  is  in  the  form  of  a pretty 
grating;  others  simply  fasten  the 
material  of  which  the  case  is  made 
across  the  door.  But  though  the 
door  be  shut,  it  is  so  arranged  as  to 
allow  the  water  to  flow  through  and 
to  bring  oxygen  to  the  thread-like 
gills,  which  are  on  the  pupae  as  well 
as  on  the  larvae.  When  ready  to 
emerge,  the  pupa  crawls  out  of  its 
case  and  climbs  to  some  object 
above  the  water,  sheds  its  pupa  skin,  and  the  adult  insect  flies  off. 
In  some  species,  living  in  swift  water,  the  adult  issues  directly  from  the 
water,  its  wings  expanding  as  soon  as  touched  by  the  air. 

Caddis-flies  are  familiar  to  us  all  even  if  we  do  not  know  them  by  name. 
They  are  night  fliers  and  flame  worshippers.  Their  parchment-like  or 
leathery  wings  are  folded  like  a roof  over  the  back,  and  from  the  side 
the  caddis-fly  appears  as  an  elongated  triangle  with  unequal  sides.  The 
front  wings  are  long  and  the  hind  ones  shorter  and  wider ; the  antennae 
are  long  and  threadlike  and  always  waving  about  for  impressions ; the 
eyes  are  round  and  beadlike ; the  tarsi,  or  feet,  are  long  and  these  insects 
have  an  awkward  way  of  walking  on  the  entire  tarsus  which  gives  them 
an  appearance  of  kneeling.  Most  of  the  species  are  dull-colored,  brown- 
ish or  gray,  the  entire  insect  often  being  of  one  color.  Caddis-flies  would 
not  be  so  fond  of  burn- 
ing themselves  in  lamps 
if  they  had  the  human 
sense  of  smell,  for  the 

stench  they  make  when  Caddis-fly.

ing.  The  mother  caddis-flies  lay  their  eggs  in  the  water.  Perhaps 
some  species  drop  the  eggs  in  when  hovering  above,  but  in  some  cases 
the  insect  must  make  a diving  bell  of  her  wings  and  go  down  into  the 
water  to  place  her  eggs  securely.  The  wings  are  covered  with  hairs 
and  not  with  scales,  and  therefore  they  are  better  fitted  for  diving  than 
would  be  those  of  the  moth.  I have  seen  caddis-flies  swim  vigorously.

LESSON  LXXXV1 
The  Caddis-worms  and  Caddis-flies 

heading  thought — The  caddis-worms  build  around  themselves  little 
houses  out  of  bits  of  sticks,  leaves  or  stones.  They  crawl  about  on  the 
bottom  of  the  pond  or  stream,  protected  from  sight,  and  able  to  withdraw 
into  their  houses  when  attacked.  The  adult  of  the  caddis-worm  is  a 
winged  moth-like  creature  which  comes  in  numbers  to  the  light  at  night. 

Method — -With  a dip-net  the  caddis-worms  may  be  captured  and  then 
may  be  placed  in  the  school  aquarium.  Duckweed  and  other  water 
plants  should  be  kept  growing  in  the  aquarium.  The  log  cabin  species  is 
best  for  this  study,  because  it  lives  in  stagnant  water  and  will  therefore 
thrive  in  an  aquarium. 

Observations — i . Where  do  you  find  the  caddis-worms  ? Can  you  see 
them  easily  on  the  bottom  of  the  stream  or  pond?  Why? 

2.  Of  what  are  the  caddis-worm  houses  made?  How  many  kinds 
have  you  ever  found?  How  many  kinds  of  materials  can  you  find  on  one 
case?  Describe  one  as  exactly  as  possible.  Find  an  empty  case  and 
describe  it  inside.  Why  is  it  so  smooth  inside?  How  is  it  made  so 
smooth?  Are  all  the  cases  the  same  size? 

3.  What  does  the  caddis-worm  do  when  it  wishes  to  walk  around? 
What  is  the  color  of  the  head  and  the  two  segments  back  of  it  ? What  is 
the  color  of  the  body?  Why  is  this  difference  of  color  between  the  head 
and  body  protective?  Is  the  caddis-worm  grown  fast  to  its  case,  as  the 
turtle  is  to  its  shell? 

4.  Note  the  legs.  Which  is  the  shorter  pair?  How  many  pairs? 
What  is  the  use  of  the  legs  so  much  shorter  than  the  others?  If  the 
caddis-worm  case  happens  to  be  wrong  side  up,  how  does  it  turn  over? 

5.  When  it  wishes  to  come  to  the  surface  or  swim,  what  does  the 
caddis-worm  do?  When  reaching  far  out  of  its  case  does  it  ever  lose  its 
hold?  How  does  it  hold  on?  Pull  the  caddis-worm  out  of  its  case  and 
see  the  hooks  at  the  end  of  the  body  with  which  it  holds  fast. 

6.  How  does  the  caddis-worm  breathe?  When  it  reaches  far  out  of 
its  case,  note  the  breathing  gills.  Describe  them.  Can  you  see  how  many 


Insect  Study  391 

there  are  on  the  segments?  How  is  the  blood  purified  through  these 
gills? 

7.  What  are  the  caddis-worm’s  enemies?  How  does  it  escape  them ? 
Touch  one  when  it  is  walking,  what  does  it  do? 

8.  On  top  of  the  first  segment  of  the  abdomen  is  a tubercle.  Do  you 
suppose  that  this  helps  to  hold  the  caddis-worm  in  its  case? 

9.  What  does  the  caddis-worm  eat?  Describe  how  it  acts  when 
eating. 

10.  How  does  the  caddis-worm  build  its  case?  Watch  one  when  it 
makes  an  addition  to  its  case,  and  describe  all  that  you  can  see. 

1 1 . Can  you  find  any  of  the  cases  with  the  front  and  back  doors  closed  ? 
How  are  they  closed?  Open  one  and  see  if  there  is  a pupa  within  it. 
Can  you  see  the  growing  wings,  antennae  and  legs?  Has  it  breathing 
filaments  like  the  larva?  Cover  the  aquarium  with  mosquito  netting  so 
as  to  get  all  the  moths  which  emerge.  See  if  you  can  discover  how  the 
pupa  changes  into  a caddis-fly. 

12.  How  does  the  caddis-fly  fold  its  wings?  What  is  the  general 
shape  of  the  insect  when  seen  from  the  side  with  wings  closed  ? What  is 
the  texture  of  the  wings?  How  many  wings  are  there?  Which  pair  is 
the  longer? 

13.  Describe  the  eyes.  The  antennae.  Does  the  caddis-fly  walk 
on  its  toes,  or  on  its  complete  foot? 

14.  Examine  the  moths  which  come  around  the  lights  at  night  in  the 
spring  and  summer.  Can  you  tell  the  caddis-flies  from  other  insects? 
Do  they  dash  into  the  light?  Do  they  seem  anxious  to  burn  themselves?

And  the  water-rats  nibble  off  the  willow  leaves  and  carry  them  below  the  wave  to 
their  nests — or  sit  on  a dry  stone  to  trim  their  whiskers. 

And  the  May-fly  practices  for  the  millionth  time  the  miracle  of  the  resurrection, 
floating  up  an  ungainly , grub  from  the  mud  below,  and  in  an  instant,  in  the  twink- 
ling of  an  eye  ( even  from  the  jaws  of  the  baffled  trout)  emerging,  an  aerial  fairy  with 
pearl-green  wings. 

And  the  caddis-fly  from  its  quaint  disguise  likewise  emerges. 

And  the  prick-eared  earth-people , the  rabbits,  in  the  stillness  of  early  morning

THE  APHIDS,  OR  PLANT-LICE 
Teacher's  Story 

KNOW  of  no  more  diverting  occupation  than 
watching  a colony  of  aphids  through  a lens ; 
these  insects  are  the  most  helpless  and  amiable 
little  ninnies  in  the  whole  insect  world;  and 
they  look  the  part,  probably  because  their 
eyes,  so  large  and  wide  apart,  seem  so  innocent 
and  wondering.  The  usual  color  of  aphids  is 
green.  As  they  feed  upon  leaves,  this  color 
protects  them  from  sight ; but  there  are  many 
species  which  are  otherwise  colored,  and  some 
have  most  bizarre  and  striking  ornamentations. 
In  looking  along  an  infested  leaf  stalk,  we  see 
them  in  all  stages  and  positions.  One  may 
have  thrust  its  beak  to  the  hilt  in  a plant  stem,  and 
is  so  satisfied  and  absorbed  in  sucking  the  juice  that 
its  hind  feet  are  lifted  high  in  the  air  and  its 
antennae  curved  backward,  making  altogether  a 
gesture  which  seems  an  adequate  expression  of  bliss ; 
another  may  conclude  to  seek  a new  well,  and  pulls 
up  its  sucking  tube,  folding  it  back  underneath  the 
body  so  it  will  be  out  of  the  way,  and  walks  off 
slowly  on  its  six  rather  stiff  legs ; when  thus  moving, 
it  thrusts  the  antennae  forward,  patting  its  pathway 
to  insure  safety.  Perhaps  this  pathway  may  lead 
over  other  aphids  which  are  feeding,  but  this  does 
not  deter  the  traveler  nor  turn  it  aside;  over  the 
backs  of  the  obstructionists  it 
crawls,  at  which  the  disturbed 
ones  kick  the  intruder  with  both 
hind  legs ; it  is  not  a vicious 
kick  but  a push  rather,  which 
says,  “This  seat  reserved,  please !” 

Perfect  bliss!  It  is  comical  to  see  a row  of  them 
sucking  a plant  stem  for  “dear  life,”  the  heads  all 
in  the  same  direction,  and  they  packed  in  and 
around  each  other  as  if  there  were  no  other  plants 
in  the  world  to  give  them  room,  the  little  ones 
wedged  in  between  the  big  ones,  until  sometimes 
some  of  them  are  obliged  to  rest  their  hind  legs  on 
the  antennae  of  the  neighbors  next  behind. 

Aphids  are  born  for  food  for  other  creatures — 
they  are  simply  little  machines  for  making  sap 
into  honey-dew,  which  they  produce  from  the 
alimentary  canal  for  the  delectation  of  ants;  they 
are,  in  fact,  merely  little  animated  drops  of  sap  on 
legs.  How  helpless  they  are  when  attacked  by  any 
one  of  their  many  enemies ! All  they  do,  when  they 
are  seized,  is  to  claw  the  air  with  their  six  impotent  Aphids  on  plant 
iegs  and  two  antennae,  keeping  up  this  performance  photo  by  siingeriand.

as  long  as  there  is  left  a leg,  and  apparently  to  the  very  last,  never  realiz- 
ing “what  is  doing.”  But  they  are  not  without  means  of  defence;  those 
two  little  tubes  at  the  end  of  the  body  are  not  for  ornament  nor  for 
producing  honey-dew  for  the  ants,  but  for  secreting  at  their  tips  a globule 
of  waxy  substance  meant  to  smear  the  eyes  of  the  attacking  insect.  I 
once  saw  an  aphid  perform  this  act,  when  confronted  by  a baby  spider;  a 
drop  of  yellow  liquid  oozed  out  of  one  tube,  and  the  aphid  almost  stood  on 
its  head  in  order  to  thrust  this  offensive  globule  directly  into  the  face  of 
the  spider — the  whole  performance  reminding  me  of  a boy  who  shakes 
his  clenched  fist  in  his  opponent’s  face  and  says,  “Smell  of  that!”  The 
spider  beat  a hasty  retreat. 

A German  scientist,  Mr.  Busgen,  discovered  that  a plant-louse  smeared 
the  eyes  and  jaws  of  its  enemy,  the  aphis- 
lion,  with  this  wax  which  dried  as  soon  as 
applied.  In  action  it  was  something  like 
throwing  a basin  of  paste  at  the  head  of  the 
attacking  party ; the  aphis-lion  thus  treated, 
was  obliged  to  stop  and  clean  itself  before  it 
could  go  on  with  its  hunt,  and  the  aphid 
walked  off  in  safety.  The  aphids  surely 
need  this  protection  because  they  have  two 
fierce  enemies,  the  larvae  of  the  aphis-lions 
and  of  the  ladybirds.  They  are  also  the  victims  of  parasitic  insects;  a 
tiny  four-winged  “fly”  lays  an  egg  within  an  aphid  ; the  larva  hatching 
from  it  feeds  upon  the  inner  portions  of  the  aphid,  causing  it  to  swell 
as  if  afflicted  with  dropsy.  Later  the  aphid  dies,  and  the  interloper 
with  malicious  impertinence  cuts  a neat  circular  door  in  the  poor  aphid’s 
skeleton  skin  and  issues  from  it  a full  fledged  insect. 

The  aphids  are  not  without  their  resources  to  meet  the  exigencies  of 
their  lives  in  colonies.  There  are  several  distinct  forms  in  each  species, 
and  they  seem  to  be  needed  for  the  general  good.  During  the  summer, 
we  find  most  of  the  aphids  on  plants  are  without  wings ; these  are  females 
which  give  birth  to  living  young  and  do  not  lay  eggs.  They  do  this  until 
the  plant  is  overstocked  and  the  food  supply  seems  to  be  giving  out,  then 
another  form  is  produced  which  has  four  wings.  These  fly  away  to  some 
other  plant  and  start  a colony  there ; but  at  the  approach  of  cold  weather, 
or  if  the  food  plants  give  out,  there  are  male  and  female  individuals 
developed,  the  females  being  always  wingless,  and  it  is  their  office  to  lay 
the  eggs  which  shall  last  during  the  long  winter  months,  when  the  living 
aphids  must  die  for  lack  of  food  plants.  The  next  spring  each  winter-egg 
hatches  into  a female  which  we  call  the  “stem  mother”  since  she  with  her 
descendants  will  populate  the  entire  plant. 

Plant-lice  vary  in  their  habits.  Some  live  in 
the  ground  on  the  roots  of  plants  and  are  very 
destructive;  but  the  greater  number  of  species 
live  on  the  foliage  of  plants  and  are  very  fond  of 
the  young,  tender  leaves  and  thus  do  great 
damage.  Some  aphids  have  their  bodies  covered 
with  white  powder  or  with  tiny  fringes,  which 
Winged  and  wingless  give  them  the  appearance  of  being  covered  with 
forms  of  plant-lice.  cotton.

The  aphids  injuring  our  flowers  and  plants  may  be  killed  by  spraying 
.ihem  with  soapsuds  made  in  the  proportion  of  one-quarter  pound  of 
ivory  soap  to  one  gallon  of  water.  The  spraying  must  be  done  very 
thoroughly  so  as  to  reach  all  the  aphids  hidden  on  the  stems  and  beneath 
the  leaves.  It  should  be  repeated  every  three  days  until  the  aphids  are 
destroyed. 

LESSON  LXXXVII 
The  Aphids,  or  Plant-lice 

Leading  thought — Aphids  have  the  mouth  in  the  form  of  a sucking  tube 
which  is  thrust  into  the  stems  and  leaves  of  plants ; through  it  the  plant 
juices  are  drawn  for  nourishment.  Aphids  are  the  source  of  honey-dew  of 
which  ants  are  fond. 

Method — Bring  into  the  schoolroom  a plant  infested  with  aphids,  place 
the  stem  in  water  and  let  the  pupils  examine  the  insects  through  the  lens. 

Observations — i.  How  are  the  aphids  settled  on  the  leaf?  Are  their 
heads  in  the  same  direction?  What  are  they  doing? 

2.  Touch  one  and  make  it  move  along.  What  does  it  do  in  order  to 
leave  its  place?  What  does  it  do  with  its  sucking  tube  as  it  walks  off? 
On  what  part  of  the  plant  was  it  feeding?  Why  does  not  Paris  green 
when  applied  to  the  leaves  of  plants  kill  aphids? 

3 . Describe  an  aphid,  including  its  eyes,  antennae,  legs  and  tubes  upon 
the  back.  Does  its  color  protect  it  from  observation? 

4.  Can  you  see  cast  skins  of  aphids  on  the  plant?  Why  does  an 
aphid  have  to  shed  its  skin? 

5.  Are  all  the  aphids  on  a plant  wingless?  When  a plant  becomes 
dry  are  there,  after  several  days,  more  winged  aphids?  Why  do  the 
aphids  need  wings  ? 

6.  Do  you  know  what  honey-dew  is?  Have  you  ever  seen  it  upon  the 
leaf?  How  is  honey-dew  made  by  the  aphids?  Does  it  come  from  the 
tubes  on  their  back?  What  insects  feed  upon  this  honey-dew? 

7.  What  enemies  have  the  aphids? 

8.  What  damage  do  aphids  do  to  plants?  How  can  you  clean  plants 
of  plant-lice  ? 

I saw  it  (an ant),  at  first,  pass,  without  stopping,  some  aphids  which  it  did  not 
however  disturb.  It  shortly  after  stationed  itself  near  one  of  the  smallest,  and 
appeared  to  caress  it,  by  touching  the  extremity  of  its  body,  alternately  with  its  anten- 
nce , with  an  extremely  rapid  movement.  I saw,  with  much  surprise,  the  fluid  proceed 
from  the  body  of  the  aphid,  and  the  ant  take  it  in  its  mouth.  Its  antennce  were  after- 
wards directed  to  a much  larger  aphid  than  the  first,  which,  on  being  caressed  after 
the  same  manner,  discharged  the  nourishing  fluid  in  greater  quantity,  which  the  ant 
immediately  swallowed:  it  then  passed  to  a third  which  it  caressed,  like  the  preced- 
ing, by  giving  it  several  gentle  blows,  with  the  antennce,  on  the  posterior  extremity  oj 
the  body;  and  the  liquid  was  ejected  at  the  same  moment,  and  the  ant  lapped  it  up „

THE  ANT-LION 
Teacher's  Story 

CHILD  is  thrilled  with  fairy  stories  of  ogres  in  their  dens, 
with  the  bones  of  their  victims  strewn  around. 
The  ants  have  real  ogres,  but  luckily,  they  do 
not  know  about  it  and  so  cannot  suffer  from 
agonizing  fears.  The  ant  ogres  seem  to  have 
depended  upon  the  fact  that  the  ant  is  so  ab- 
-^sorbed  in  her  work  that  she  carries  her  booty  up 
hill  and  down  dale  with  small  regard  for  the 
topography  of  the  country.  Thus  they  build 
their  pits,  with  instinctive  faith  that  they  will 
some  day  be  entered  by  these  creatures, 
obsessed  by  industry  and  careless  of  what  lies  in  the  path.  The  pits 
vary  with  the  size  of  the  ogre  at  the  bottom ; there  are  as  many  sized 
pits  as  are  beds  in  the  story  of  Golden  Locks  and  the  bears ; often  the 
pits  are  not  more  than  an  inch  across,  or  even  less,  while  others  are  two 
inches  in  diameter.  They  are  always  made  in  sandy  or  crumbly  soil  and 
in  a place  protected  from  wind  and  rain;  they  vary  in  depth  in  propor- 
tion to  their  width,  for  the  slope  is  always  as  steep  as  the  soil  will  stand 
without  slipping. 

All  that  can  be  seen  of  the  ogre  at  the  bottom,  is  a pair  of  long,  curved 
jaws,  looking  innocent  enough  at  the  very  center  of  the  pit.  If  we  dig  the 
creature  out,  we  find  it  a comical  looking  insect.  It  is  humpbacked,  with 
a big,  spindle-shaped  abdomen;  from  its  great  awkward  body  projects  a 
flat,  sneaking  looking  head,  armed  in  front  with  the  sickle  jaws  which  are 
spiny  and  bristly  near  the  base,  and  smooth,  sharp  and  curved  at  the  tip. 
The  strange  thing  about  these  jaws  is  that  they  lead  directly  to  the  throat, 
since  the  ant-lion  has  no  mouth.  Each  jaw  is  made  up  of  two  pieces 
which  are  grooved  where  they  join  and  thus  form  a tube  with  a hole  in 
the  tip  through  which  the  industrious  blood  of  the  ants  can  be  sucked; 
not  only  do  the  sharp  sickle  points  hold  the  victim,  but  there  are  three 
teeth  along  the  side  of  each  jaw  to  help  with  this.  The  two  front  pairs  of 
legs  are  small  and  spiny ; the  hind  legs  are  strong  and  peculiarly  twisted, 
and  have  a sharp  spikelike  claw  at  the  end,  which  is  so  arranged  as  to  push 
the  insect  backward  vigorously  if  occasion  requires;  in  fact,  the  ant-lion 
in  walking  about,  moves  more  naturally  backward  than  forward  because 
of  the  peculiar  structure  of  his  legs. 

Having  studied  the  ogre, 
we  can  see  better  how  he 
manages  to  trap  his  victim. 

As  the  ant  goes  scurrying 
along,  she  rushes  over  the 
edge  of  the  pit  and  at  once 
begins  to  slide  downward; 
she  is  frightened  and 
strugglesto  get  back;  just 
then  a jet  of  sand,  aimed 
well  from  the  bottom  of  the 

pit  hits  her  and  knocks  her  Ant_Uon  wUh  tts  CK00n  amJ  brm 

back.  She  Still  struggles.  Comstock's  Manual. 


396 


Handbook  of  Nature-Study 


and  there  follows  a fusillade  of  sand  jets,  each  hitting  her  from  above  and 
knocking  her  down  to  the  fatal  center  where  the  sickle  jaws  await  her 
and  are  promptly  thrust  into  her ; if  she  is  large  and  still  struggles,  the 
big,  unwieldy  body  of  the  ogre,  buried  in  the  sand,  anchors  him  fast 
and  his  peculiar,  crooked  hind  legs  push  his  body  backward  in  this 
strange  tug  of  war;  thus,  the  ant-ogre  is  not  dragged  out  of  his  den 
by  the  struggles  of  the  ant,  and  soon  the  loss  of  blood  weakens  her  and 
she  shrivels  up. 

The  secret  of  the  jets  of  sand,  lies  in  the  flat  head  of  the  ogre;  if 
we  look  at  it  regarding  it  as  a shovel,  we  can  see  that  it  is  well  fitted 
for  its  purpose;  for  it  is  a shovel  with  a strong  mechanism  working  it. 
In  fact,  the  whole  pit  is  dug  with  this  shovel  head.  Wonderful  stories 
are  told  about  the  way  that  ant-lions  dig  their  pits,  marking  out  the  outer 
margin  in  a circle,  and  working  inward.  However,  our  common  ant-lion 
of  the  East  simply  digs  down  into  the  sand  and  flips  the  sand  out  until  it 
makes  a pit.  If  an  ant-lion  can  be  caught  and  put  in  a jar  of  sand  it 
will  soon  make  its  pit,  and  the  process  may  be  noted  carefully. 

There  is  one  quality  in  the  ogre  which  merits  praise,  and  that  is  his 
patience.  There  he  lies  in  his  hole  for  days  or  perhaps  weeks,  with  noth- 
ing to  eat  and  no  ant  coming  that  way;  so  when  we  see  an  absent-minded 
ant  scrambling  over  into  the  pit,  let  us  think  of  the  empty  stomach  of  this 
patient  little  engineer  which  has  constructed  his  pit  with  such  accuracy 
and  so  much  labor.  So  precarious  is  the  living  packed  up  by  the  ant-lions, 
that  it  may  require  one,  two  or  three  years  to  bring  one  to  maturity. 
At  that  time  it  makes  a perfectly  globular  cocoon  of  silk  and  sand,  the 
size  of  a large  pea,  and  within  it,  changes  to  a pupa;  and  when  finally 
ready  to  emerge,  the  pupa  pushes  itself  part  way  out  of  the  cocoon  and  the 
skin  is  shed  and  left  at  the  cocoon  door.  The  adult  resembles  a small 
dragon-fly;  it  has  large  net -veined  wings  and  is  a most  graceful  insect,  as 
different  as  can  be  from  the  humpbacked  ogre  which  it  once  was — a 
transformation  quite  as  marvelous  as  that  which  occurred  in  Beauty  and 
the  Beast.  Throughout  the  Middle  West,  the  ant-lion  in  its  pit  is  called 
the  “doodle-bug.”

LESSON  LXXXVIII 
The  Ant-Lion 

Leading  thought — The  ant-lion,  or  “doodle-bug”  makes  a little  pit  in 
the  sand  with  very  steep  sides,  and  hidden  at  the  bottom  of  it,  waits  for 
ants  to  tumble  in  to  be  seized  by  its  waiting  jaws.  Later  the  ant-lion 
changes  to  a beautiful  insect  with  gauzy  wings,  resembling  a small  dragon- 
fly. 

Method — The  pupils  should  see  the  ant-lion  pits  in  their  natural  situa- 
tions, but  the  insects  may  be  studied  in  the  schoolroom.  Some  of  the 
ant-lions  may  be  dug  out  of  their  pits  and  placed  in  a dish  of  sand.  They 
will  soon  make  their  pits,  and  may  be  watched  during  this  interesting 
process.  It  is  hardly  advisable  to  try  to  rear  these  insects,  as  they  may 
require  two  or  three  years  for  development. 

Observations — i.  Where  were  the  ant-lion  pits  out  of  doors?  Were 
they  in  a windy  place?  Were  they  in  a place  protected  from  storms? 
In  what  kind  of  soil  were  they  made?

2.  Measure  one  of  the  pits.  How  broad  across,  and  how  deep?  Are 
all  the  pits  of  the  same  size  ? Why  ? 

3.  What  can  you  see  as  you  look  down  into  the  ant-lion’s  pit?  Roll 
a tiny  pebble  in  and  see  what  happens  ? Watch  until  an  ant  comes  hurry- 
ing along  and  slips  into  the  pit.  What  happens  then?  As  she  struggles 
to  get  out  how  is  she  knocked  back  in?  What  happens  to  her  if  she  falls 
to  the  bottom? 

4.  Take  a trowel  and  dig  out  the  doodle-bug.  What  is  the  shape  of 
its  body?  What  part  of  the  insect  did  you  see  at  the  bottom  of  the  pit? 
Do  you  know  that  these  great  sickle-shaped  jaws  are  hollow  tubes  for 
sucking  blood?  Does  the  ant-lion  eat  anything  except  the  blood  of  its 
victim  ? 

5.  Can  you  see  that  the  ant-lion  moves  backward  more  easily  than 
forward?  How  are  its  hind  legs  formed  to  help  push  it  backward?  How 
does  this  help  the  ant-lion  in  holding  its  prey  ? How  does  the  big  awk- 
ward body  of  the  ant-lion  help  to  hold  it  in  place  at  the  bottom  of  the  pit 
when  it  seizes  an  ant  in  its  jaws? 

6.  What  shape  is  the  ant-lion’s  head?  How  does  it  use  this  head  in 
taking  its  prey?  In  digging  its  pit? 

7.  Take  a doodle-bug  to  the  schoolroom,  place  it  in  a dish  of  sand, 
covered  with  glass,  and  watch  it  build  its  pit. 

8.  Read  in  the  entomological  books  about  the  cocoon  of  the  ant-lion 
and  what  the  adult  looks  like,  and  then  write  an  ant-lion  autobiography.

THE  MOTHER  LACE-WING  AND  THE  APHIS-LION 

Teacher's  Story 

LITTING  leisurely  through  the  air  on  her  green  gauze 
wings,  the  lace-wing  seems  like  a filmy  leaf,  broken 
loose  and  drifting  on  the  breeze.  But  there  is  pur- 
pose in  her  flight,  and  through  some  instinct  she  is 
enabled  to  seek  out  an  aphis-ridden  plant  or  tree, 
to  which  she  comes  as  a friend  in  need.  As  she 
alights  upon  a leaf,  she  is  scarcely  discernible  because 
of  the  pale  green  of  her  delicate  body  and  wings; 
however,  her  great  globular  eyes  that  shine  like  gold 
attract  the  attention  of  the  careful  observer.  But 
though  she  is  so  fairy-like  in  appearance,  if  you  pick 
her  up,  you  will  be  sorry  if  your  sense  of  smell  is  keen,  for  she  exhales  a 
most  disagreeable  odor  when  disturbed — a habit  which  probably  protects 
her  from  birds  or  other  creatures  which  might  otherwise  eat  her. 

However,  if  we  watch  her  we  shall  see  that  she  is  a canny  creature 
despite  her  frivolous  appearance ; her  actions  are  surely  peculiar.  A drop 
of  sticky  fluid  issues  from  the  tip  of  her  body,  and  she  presses  it  down  on 
the  surface  of  the  leaf ; then  lifting  up  her  slender  abdomen  like  a distaff, 
she  spins  the  drop  into  a thread  a half  inch  long  or  more,  which  the  air 
soon  dries ; and  this  silken  thread  is  stiff  enough  to  sustain  an  oblong  egg, 
as  large  as  the  point  of  a pin,  which  she  lays  at  the  very  tip  of  it.  This 
done  she  lays  another  egg  in  a like  manner,  and  when  she  is  through,  the 


39^ 


Handbook  of  Nature-Study 


leaf  looks  as  if  it  were  covered  with  spore  cases  of  a glittering  white  mold. 
This  done  she  flies  off  and  disports  herself  in  the  sunshine,  care  free,  know- 
ing that  she  has  done  all  she  can  for  her  family. 

After  a few  days  the  eggs  begin  to  look  dark,  and  then  if  we  examine 
them  with  a lens,  we  may  detect  that  they  contain  little  doubled-up 
creatures.  The  first  we  see  of  the  egg  inmate  as  it  hatches,  is  a pair  of 
jaws  thrust  through  the  shell,  opening  it  for  a peep-hole;  a little  later  the 
owner  of  the  jaws,  after  resting  a while  with  an  eye  on  the  world  which  he 
is  so  soon  to  enter,  pushes  out  his  head  and  legs  and  drags  out  a tiny,  long 
body,  very  callow-looking  and  clothed  in  long,  soft  hairs.  At  first  the 

little  creature  crawls  about 
his  egg-shell,  clinging  tightly 
with  all  his  six  claws,  as  if 
fearful  of  such  a dizzy  height 
above  his  green  floor;  then 
he  squirms  around  a little  and 
thrusts  out  a head  inquiringly 
while  still  hanging  on  “for 
dear  life.”  Finally  he  gains 
courage  and  prospects  around 
until  he  discovers  his  egg 
stalk,  and  then  begins  a rope 
climbing  performance,  rather 
difficult  for  a little  chap  not 
more  than  ten  minutes  old. 
He  takes  a careful  hold  with 
his  front  claws,  the  two  other 
pairs  of  legs  carefully  balanc- 
ing for  a second,  and  then 
desperately  seizing  the  stalk 
with  all  his  clasping  claws, 
and  with  many  new  grips  and  panics,  he  finally  achieves  the  bottom 
in  safety.  As  if  dazed  by  his  good  luck,  he  stands  still  for  a time, 
trying  to  make  up  his  mind  what  has  happened  and  what  to  do  next ; he 
settles  the  matter  by  trotting  off  to  make  his  first  breakfast  of  aphids; 
and  now  we  can  see  that  it  is  a lucky  thing  for  his  brothers  and  sisters, 
still  unhatched,  that  they  are  high  above  his  head  and  out  of  reach,  for  he 
might  not  be  discriminating  in  the  matter  of  his  breakfast  food,  never 
having  met  any  of  his  family  before.  He  is  a queer  looking  little  insect, 
spindle-shaped  and  with  peculiarly  long,  sickle-shaped  jaws  projecting 
from  his  head.  Each  of  these  jaws  is  made  up  of  two  pieces  joined  length- 
wise so  as  to  make  a hollow  tube,  which  has  an  opening  at  the  tip  of  the 
jaw,  and  another  one  at  the  base  which  leads  directly  to  the  little  lion’s 
throat.  Watch  him  as  he  catches  an  aphid;  seizing  the  stupid  little  bag 
of  sap  in  his  great  pincers,  he  lifts  it  high  in  the  air,  as  if  drinking  a 
bumper,  and  sucks  its  green  blood  until  it  shrivels  up,  kicking  a remon- 
strating leg  to  the  last.  It  is  my  conviction  that  aphids  never  realize 
when  they  are  being  eaten ; they  simply  dimly  wonder  what  is  happening. 

It  takes  a great  many  aphids  to  keep  an  aphis-lion  nourished  until  he 
gets  his  growth ; he  grows  like  any  other  insect  by  shedding  his  skeleton 
skin  when  it  becomes  too  tight.  Finally  he  doubles  up  and  spins  around 
himself  a cocoon  of  glistening  white  silk,  leaving  it  fastened  to  the  leaf;

when  it  is  finished,  it  looks  like  a seed  pearl,  round  and  polished.  I 
wish  some  child  would  watch  an  aphis-lion  weave  its  cocoon  and  tell  us 
how  it  is  done ! After  a time,  a week  or  two  perhaps,  a round  little  hole  is 
cut  in  the  cocoon,  and  there  issues  from  it  a lively  little  green  pupa,  with 
wing  pads  on  its  back ; but  he  very  soon  sheds  his  pupa  skin  and  issues 
as  a beautiful  lace-wing  fly  with  golden  eyes  and  large,  filmy,  iridescent, 
pale  green  wings,

Leading  thought — The  lace-wing  fly  or  golden-eyes,  as  she  is  called,  is 
the  mother  of  the  aphis-lion.  She  lays  her  eggs  on  the  top  of  stiff,  silken 
stalks.  The  young  aphis-lions  when  hatched,  clamber  down  upon  the  leaf 
and  feed  upon  plant-lice,  sucking  their  blood  through  their  tubular  jaws. 

Method — Through  July  and  until  frost,  the  aphis-lions  may  be  found 
on  almost  any  plant  infested  with  plant -lice ; and  the  lace-wing’s  eggs  or 
egg-shells  on  the  long  stalks  are  also  readily  found.  All  these  may  be 
brought  to  the  schoolroom.  Place  the  stem  of  a plant  infested  with 
aphids  in  a jar  of  water,  and  the  acts  of  the  aphis-lions  as  well  as  the 
habits  of  the  aphids  may  be  observed  during  recess  or  at  other  convenient 
times,  by  all  the  pupils. 

Observations — i . When  you  see  a leaf  with  some  white  mold  upon  it, 
examine  it  with  a lens ; the  mold  is  likely  to  be  the  eggs  of  the  lace- wing. 
Is  the  egg  as  large  as  a pin  head?  What  is  its  shape ? What  is  its  color? 
How  long  is  the  stalk  on  which  it  is  placed?  Of  what  material  do  you 
think  the  stalk  is  made?  Why  do  you  suppose  the  lace- wing  mother  lays 
her  eggs  on  the  tips  of  stalks?  Are  there  any  of  these  eggs  near  each 
other  on  the  leaf? 

2.  If  the  egg  is  not  empty,  observe  through  a lens  how  the  young 
aphis-lion  breaks  its  egg-shell  and  climbs  down. 

3.  Watch  an  aphis-lion  among  the  plant-lice.  How  does  it  act? 
Do  the  aphids  seem  afraid?  Does  the  aphis-lion  move  rapidly?  How 
does  it  act  when  eating  an  aphid  ? 

4.  What  is  the  general  shape  of  the  aphis-lion?  Describe  the  jaws. 
Do  you  think  these  jaws  are  used  for  chewing,  or  merely  as  tubes  through 
which  the  green  blood  of  the  aphids  is  sucked?  Do  the  aphis-lions  ever 
attack  each  other  or  other  insects?  How  does  the  aphis-lion  differ  in 
appearance  from  the  ladybird  larva? 

5.  What  happens  to  the  aphis-lion  after  it  gets  its  growth?  Describe 
its  cocoon  if  you  can  find  one. 

6.  Describe  the  little  lace-wing  fly  that  comes  from  the  cocoon. 
Why  is  she  called,  golden-eyes?  Why  lace-wing?  Does  she  fly  rapidly? 
Do  you  suppose  that  if  she  should  lay  her  eggs  flat  on  a leaf,  that  the  first 
aphis-lion  that  hatched  would  run  about  and  eat  all  its  little  brothers  and 
sisters  which  were  still  in  their  egg-shells  ? How  do  the  aphis-lions  benefit 
our  rose  bushes  and  other  cultivated  plants?

THE  MOSQUITO 
T eacher's  Story 

N DEFIANCE  of  the  adage,  the  mother  of  ourmost 
common  mosquitoes  does  not  hesitate  to  put  her 
eggs  all  in  one  basket,  but  perhaps  she  knows  it  is 
about  the  safest  little  basket  for  eggs  in  this  world 
of  uncertainties.  If  it  were  possible  to  begin  this 
lesson  with  the  little  boat-shaped  egg  baskets,  I 
should  advise  it.  They  may  be  found  in  almost 
any  rain  barrel,  and  the  eggs  look  like  a lot  of  tiny 
cartridges  set  side  by  side,  points  up,  and  lashed 
or  glued  together,  so  there  shall  be  no  spilling. 
Like  a certain  famous  soap,  they  “float,”  coming  up 
as  dry  as  varnished  corks  when  water  is  poured  upon  them. 

The  young  mosquito,  or  wrig- 
gler, breaks  through  the  shell  of 
the  lower  end  of  the  egg  and 
passes  down  into  the  water,  and 
from  the  first,  it  is  a most  in- 
teresting creature  to  view 
through  a hand  lens.  The  head 
and  the  thorax  are  rather  large 
while  the  body  is  tapering  and 

armed  with  bunches  of  hairs.  At  the  rear  of  the  body  are  two  tubes  very 
different  in  shape;  one  is  long,  straight  and  unadorned;  this  is  the 
breathing  tube  through  which  air  passes  to  the  tracheae  of  the  body. 
This  tube  has  a star-shaped  valve  at  the  tip,  which  can  be  opened  and 
shut;  when  it  is  opened  at  the  surface  of  the  water,  it  keeps  the 
little  creature  afloat  and  meanwhile  allows  air  to  pass  into  the  body. 
When  the  wriggler  is  thus  hanging  at  an  angle  of  45  degrees  to  the 
surface  of  the  water,  it  feeds  upon  small  particles  of  decaying  vegeta- 
tion; it  has  a remarkable  pair  of  jaws  which 
are  armed  with  brushes,  which  in  our 
common  species,  by  moving  rapidly,  set  up 
currents  and  bring  the  food  to  the  mouth.  This 
process  can  be  seen  plainly  with  a lens. 
When  disturbed,  the  wriggler  shuts  the  valve  to 
its  breathing  tube,  and  sinks.  However,  it  is 
not  much  heavier  than  the  water;  I have  often 
seen  one  rise  for  some  distance  without  apparent 
effort.  The  other  tube  at  the  end  of  the  body, 
supports  the  swimming  organs,  which  consist  of 
four  finger-like  processes  and  various  bunches  of 
hairs.  When  swimming,  the  wriggler  goes  tail 
first,  the  swimming  organs  seeming  to  take 
hold  of  the  water  and  to  pull  the  creature  back- 
ward, in  a series  of  spasmodic  jerks;  in  fact, 
the  insect  seems  simply  to  “throw  somer- 
saults,” like  an  acrobat.  I have  often  observed 
wrigglers  standing  on  their  heads  in  the 
bottom  of  the  aquarium,  with  their  jaws  bent

under,  revolving  their  brushes 
briskly;  but  they  never  remain 
very  long  below  the  surface,  as  it  is 
necessary  for  them  to  take  in  fresh 
air  often. 

The  pupa  has  the  head  and 
thoracic  segments  much  enlarged, 
making  it  all  “head  and  shoulders” 
with  a quite  insignificant 
body  attached.  Upon  the 
thorax  are  two  breathing 
tubes,  which  look  like  two 
ears,  and  therefore  when 
the  pupa  rests  at  the  sur- 
face of  the  water,  it  remains 
head  up  so  that  these  tubes 
may  take  in  the  air;  at  the 
end  of  the  body  are  two 
swimming  organs  which  are  little, 
leaf -like  projections.  At  this  stage 
the  insect  is  getting  ready  to  live 
its  life  in  the  air,  and  for  this  reason 
probably,  the  pupa  rests  for  long 
periods  at  the  surface  of  the 
water  and  does  not  swim  about 
much,  unless  disturbed.  How- 
ever, it  is  a very  strange  habit 
for  a pupa  to  move  about  at  all. 

In  the  case  of  other  flies,  butterflies, 
and  moths,  the  pupa  stage  is  quiet. 

When  fully  mature,  the  pupa 
rises  to  the  surface  of  the  water, 
the  skeleton  skin  breaks  open 
down  its  back  and  the  mosquito 
carefully  works  itself  out,  until 
its  wings  are  free  and  dry,  mean- 
while resting  upon  the  floating 
pupa  skin.  This  is  indeed  a frail 
bark,  and  if  the  slightest  breeze 
ruffles  the  water,  the  insect  is 
likely  to  drown  before  its  wings 
are  hard  enough  for  flight. 

The  reason  that  kerosene  oil, 
put  upon  the  surface  of  the  water 
where  mosquitoes  breed,  kills  the 
insects  is  because  both  the  larvae 
and  pup®  of  mosquitoes  are 
obliged  to  rise  to  the  surface,  and  push  their  breathing  tubes  through 
the  surface  film  so  that  they  will  open  to  the  air;  a coating  of  oil  on  the 
water  prevents  this,  and  they  are  suffocated.  Also  when  the  mosquito 
emerges  from  the  pupa  skin,  if  it  is  even  touched  by  the  oil,  it  is  unable 
to  fly  and  soon  dies.

Handbook  of  Nature-Study 


The  male  mosquitoes  have  bushy,  or  feathery,  antennas  These 
antennae  are  hearing  organs  of  very  remarkable  construction;  (see  Ways 
of  the  Six-Footed,  p.  8.)  The  Anopheles  may  be  distinguished  from  the 
Culex  by  the  following  characteristics : Its  wings  are  spotted  instead  of 

plain.  When  at  rest  it  is  perfectly  straight, 
and  is  likely  to  have  the  hind  legs  in  the  air. 
It  may  also  rest  at  an  angle  to  the  surface 
to  which  it  clings.  The  Culex  is  not 
spotted  on  the  wings  and  is  likely  to  be 
humped  up  when  at  rest.  In  our  climate 
the  Anopheles  is  more  dangerous  than  the 
Culex  because  it  carries  the  germs  of 
malaria.  A mosquito’s  wing  under  a 
microscope  is  a most  beautiful  object,  as  it 
is  “trimmed”  with  ornamental  scales  about 
the  edges  and  along  the  veins.  The  male 
mosquitoes  neither  sing  nor  bite ; the  song  of  the  female  mosquito  is 
supposed  to  be  made  by  the  rapid  vibration  of  the  wings,  and  her 
musical  performances  are  for  the  purpose  of  attracting  her  mate,  as 
it  has  been  shown  that  he  can  hear  through  his  antennae  a range  of  notes 
covering  the  middle  and  next  higher  octaves  of  the  piano. 

Of  late  we  are  learning  that  the  mosquitoes  are  in  a very  strange  way  a 
menace  to  health.  Through  a heroism,  as  great  as  ever  shown  on  field  of 
battle,  men  have  imperiled  their  lives  to  prove  that  the  germs  of  the  terri- 
ble yellow  fever  were  transmitted  by  the  biting  mosquito,  and  with 
almost  equal  bravery  other  men  have  demonstrated  that  the  germs  of 
malaria  are  also  thus  carried. 

In  the  North,  our  greatest  danger  is  from  the  mosquitoes  which  carry 
the  malarial  germs,  and  these  are  the  mosquitoes  with  spotted  wings  and 
belong  to  the  genus  Anopheles.  This  mosquito,  in  order  to  be  of  danger 
to  us  must  first  feed  upon  the  blood  of  some  person  suffering  from  malaria 
(ague)  and  thus  take  the 
germ  of  the  disease  into  its 
stomach.  Here  the  germ 
develops  and  multiplies  into 
many  minute  germs,  which 
pass  through  another  stage 
and  finally  get  into  the 
blood  of  the  mosquito  and 
accumulate  in  the  salivary 
glands.  The  reason  any 
mosquito  bite  or  insect  bite 
swells  and  itches  is  because, 
as  the  insect’s  beak  is  inser- 
ted into  the  flesh,  it  carries 
with  it  some  of  the  saliva 
from  the  insect’s  mouth.  In 
the  case  of  Anopheles  these 
malarial  germs  are  carried 

with  the  saliva  into  the  blood  The  pupa  of  a mosquito,  greatly  magnified.  Note

nalarial  countries,  like  Italy  and  India,  people  are  entirely  free  from 
malaria  if  they  are  not  bitten  by  mosquitoes. 

After  this  explanation  has  been  made,  it  would  be  well  for  the  teacher 
Jo  take  the  pupils  on  a tour  of  inspection  through  the  neighborhood  to  see 
if  there  are  any  mosquito  larvae  in  rain  barrels,  ponds  or  pools  of  stagnant 
water.  If  such  places  are  found,  let  the  pupils  themselves  apply  the 
following  remedies : 

1.  Rain  barrels  should  be  securely  covered. 

2.  All  stagnant  pools  should  be  drained  and  filled  up  if  possible. 

3.  Wherever  there  are  ponds  or  pools  where  mosquitoes  breed  that 
cannot  be  filled  or  drained,  the  surface  of  the  water  should  be  covered 
with  a spray  of  kerosene  oil.  This  may  be  applied  with  a spray  pump  or 
from  a watering  can. 

4.  If  it  is  impracticable  to  cover  such  places  with  oil,  introduce  into 

such  pools  the  following  fish : Minnows,  sticklebacks,  sunfish  and  gold- 

fish. 

The  effect  of  this  lesson  upon  the  children  should  be  to  impress  them 
with  the  danger  to  life  and  health  from  mosquitoes  and  to  implant  in  them 
a determination  to  rid  the  premises  about  their  homes  of  these  pests.

LESSON  XC 
The  Mosquito 

Leading  thought — The  wrigglers,  or  wigglers,  which  we  find  in  rain- 
barrels  and  stagnant  water  are  the  larvae  of  mosquitoes.  We  should 
study  their  life  history  carefully  if  we  would  know  how  to  get  rid  of 
mosquitoes. 

Method — There  is  no  better  way  to  interest  the  pupils  in  mosquitoes 
than  to  place  in  an  aquarium  jar  in  the  schoolroom  a family  of  wrigglers 
from  some  pond  or  rain  barrel.  For  the  pupils’  personal  observation , take 
some  of  the  wrigglers  from  the  aquarium  with  a pipette  and  place  them  in 
a homeopathic  vial;  fill  the  vial  three-fourths  full  of  water  and  cork  it. 
Pass  it  around  with  a hand  lens  and  give  each  pupil  the  opportunity  to 
observe  it  for  five  or  ten  minutes.  It  would  be  well  if  this  vial  could  be 
left  on  each  desk  for  an  hour  or  so  during  study  periods,  so  that  the 


404 


Handbook  of  Nature-Study 

observations  may  be  made  casually  ancl  leisurely.  While  the  pupils  are 
studying  the  wrigglers,  the  following  questions  should  be  placed  upon  the 
blackboard,  and  each  pupil  should  make  notes  which  may  finally  be  given 
at  a lesson  period.  This  is  particularly  available  work  for  September. 

In  studying  the  adult  mosquito,  a lens  or  microscope  is  necessary.  But 
it  is  of  great  importance  that  the  pupils  be  taught  to  discriminate  between 
the  comparatively  harmless  species  of  Culex  and  the  dangerous  Anopheles 
and  therefore  they  should  be  taught  to  be  observant  of  the  way  mosqui- 
toes rest  upon  the  walls,  and  whether  they  have  mottled  or  clear  wings. 

The  Larva 

Observations:  i.  Note  if  all  the  wrigglers  are  of  the  same  gen 

eral  shape,  or  if  some  of  them  have  a very  large  head;  these  latter  are 
the  pupae  and  the  former  are  the  larvae.  We  will  study  the  larvae  first. 
Where  do  they  rest  when  undisturbed?  Do  they  rest  head  up  or  down? 
Is  there  any  part  of  their  body  that  comes  to  the  surface  of  the  water? 

2.  When  disturbed  what  do  they  do?  When  they  swim,  do  they  go 
head  or  tail  first?  When  they  float  do  they  go  upward  or  downward? 

3.  Observe  one  resting  at  the  top.  At  what  angle  does  it  hold  itself 
to  the  surface  of  the  water?  Observe  its  head.  Can  you  see  the  jaw 
brushes  revolving  rapidly?  What  is  the  purpose  of  this?  Describe  its 
eyes.  Can  you  see  its  antennas? 

4.  Note  the  two  peculiar  tubes  at  the  end  of  the  body  and  see  if  you 
can  make  out  their  use. 

5.  Note  especially  the  tube  that  is  thrust  up  to  the  surface  of  the 
water  when  the  creatures  are  resting.  Can  you  see  how  the  opening  of 
this  tube  helps  to  keep  the  wriggler  afloat?  What  do  you  think  is  the 
purpose  of  this  tube  ? Why  does  it  not  become  filled  with  water  when  the 
wriggler  is  swimming  ? Can  you  see  the  two  air  vessels,  or  trachae,  extend- 
ing from  this  tube  along  the  back  the  whole  length  of  the  body  ? 

6.  Note  the  peculiarities  of  the  other  tube  at  the  rear  end  of  the  body. 
Do  you  think  the  little  finger-like  projections  are  an  aid  in  swimming? 
How  many  are  there? 

7.  Can  you  see  the  long  hairs  along  the  side  of  the  body? 

8.  Does  the  mosquito  rest  at  the  bottom  of  the  bottle  or  aquarium? 

The  Pupa 

9.  What  is  the  most  noticeable  difference  in  appearance  between 
the  larva  and  pupa? 

10.  When  the  pupa  rests  at  the  surface  of  the  water,  is  it  the  same  end 
up  as  the  wriggler? 

1 1 . Note  on  the  “head”  of  the  pupa  two  little  tubes  extending  up  like 
ears.  These  are  the  breathing  tubes.  Note  if  these  open  to  the  air  when 
the  pupa  rests  at  the  surface  of  the  water. 

1 2 . Can  you  see  the  swimming  organs  at  the  rear  of  the  body  of  the 
pupa?  Does  the  pupa  spend  a longer  time  resting  at  the  surface  than  the 
larva.  How  does  it  act  differently  from  the  pupas  of  other  flies  and 
moths  and  butterflies  ? 

13.  How  does  the  mosquito  emerge  from  the  pupa  skin?  Why  does 
kerosene  oil  poured  on  the  surface  of  the  water  kill  mosquitoes  ?

The  Adult  Mosquito 

1.  Has  the  mosquito  feathery  antennae  extending  out  in  front?  If 
so,  what  kind  of  mosquitoes  are  such  ? 

2.  Do  the  mosquitoes  with  bushy  antennae  bite?  Do  they  sing? 

3 . Are  the  wings  of  the  mosquito  spotted  or  plain  ? How  many  has  it  ? 

4.  When  at  rest,  is  it  shortened  and  humpbacked  or  does  it  stand 
straight  out  with  perhaps  its  hind  legs  in  the  air  ? 

5.  What  are  the  characteristics  by  which  you  can  tell  the  dangerous 
Anopheles? 

6.  Why  is  the  Anopheles  more  dangerous  than  the  Culex? 

7.  Examine  a mosquito’s  wing  under  a microscope  and  describe  it. 

8.  Examine  the  antennae  of  a male  and  a female  mosquito  under  a 
microscope,  and  describe  the  difference. 

9.  Which  sex  of  the  mosquito  does  the  biting  and  the  singing? 

10.  How  is  the  singing  done? 


THE  HOUSE-FLY 
Teacher's  Story 

house-fly  is  surely  an  up-to-date  member  of  that 
select  class  which  evolutionists  call  the  “fit.”  It 
flourishes  in  every  land,  plumping  itself  down  in 
front  of  uS  at  table,  whether  we  be  eating  rice  in 
Hong  Kong,  dhura  in  Egypt,  macaroni  in  Italy,  pie 
in  America,  or  tamales  in  Mexico.  There  it  sits, 
impertinent  and  imperturbable,  taking  its  toll, 
letting  down  its  long  elephant-trunk  tongue,  rasping 
and  sucking  up  such  of  our  meal  as  fits  its  needs. 
As  long  as  we  simply  knew  it  as  a thief  we,  during 
untold  ages,  merely  slapped  it  and  shooed  it,  which 
effort  on  our  part  apparently  gave  it  exhilarating  exercise.  But  during 
recent  years  we  have  begun  trapping  and  poisoning,  trying  to  match  our 
brains  against  its  agility ; although  we  slay  it  by  thousands,  we  seem  only 
to  make  more  room  for  its  well-fed  progeny  of  the  future,  and  in  the  end 
we  seem  to  have  gained  nothing.  But  the  most  recent  discoveries  of 
science  have  revealed  to  us,  that  what  the  house-fly  takes  of  our  food,  is 
of  little  consequence  to  what  it  leaves  behind.  Because  of  this,  we  have 
girded  up  our  loins  and  gone  into  battle  in  earnest. 

I have  always  held  that  nature-study  should  follow  its  own  peaceful 
path  and  not  be  the  slave  of  economic  science.  But  occasionally  it  seems 
necessary,  when  it  is  a question  of  creating  public  sentiment,  and  of  cul- 
tivating public  intelligence  in  combating  a great  peril,  to  make  nature- 
study  a handmaiden,  if  not  a slave,  in  this  work.  If  our  woods  were  filled 
with  wolves  and  bears,  as  they  were  in  the  days  of  my  grandfather,  I 
should  give  nature-study  lessons  on  these  animals,  which  would  lead  to 
their  subjugation.  Bears  and  wolves  trouble  us  no  more;  but  now  we 
have  enemies  far  more  subtle,  in  the  ever-present  microbes,  which  we  may 
never  hope  to  conquer  but  which,  with  proper  precautions,  we  may  render 
comparatively  harmless.  Thus,  our  nature-study  with  insects  which 


406 


Handbook  of  Nature-Study 


carry  disease,  like  the  mosquitoes,  flies  and  fleas,  must  be  a reconnaissance 
for  a war  of  extermination ; the  fighting  tactics  may  be  given  in  lessons 
on  health  and  hygiene. 

Perhaps  if  a fly  were  less  wonderfully  made,  it  would  be  a less  con- 
venient vehicle  for  microbes.  Its  eyes  are  two  great,  brown  spheres  on 
either  side  of  the  head,  and  are  composed  of  thousands  of  tiny  six-sided 
eyes  that  give  information  of  what  is  coming  in  any 
direction ; in  addition,  it  has  on  top  of  the  head,  looking 
straight  up,  three  tiny,  shining,  simple  eyes,  which  cannot 
be  seen  without  a lens.  Its  antennae  are  peculiar  in 
shape,  but  are  evidently  sense  organs ; it  is  attracted  from 
afar  by  certain  odors,  and  so  far  as  we  can  discover,  its 
antennas  are  all  the  nose  it  has.  Its  mouth-parts  are  all 
combined  to  make  a most  amazing  and  efficient  organ 
for  getting  food ; at  the  tip  are  two  flaps,  which  can  rasp  a 
substance  so  as  to  set  free  the  juices,  and  above  this  is  a

jointed  so  that  it  can  be  folded  under  the  “chin”  when 
not  in  use.  This  is  usually  called  the  fly’s  tongue,  but  it  is  really  all 
the  mouth  parts  combined,  as  if  a boy  had  his  lips,  teeth  and  tongue, 
standing  out  from  his  face,  at  the  end  of  a tube  a foot  long. 

The  thorax  can  be  easily  studied ; it  is  striped  black  and  white  above 
and  bears  the  two  wings,  and  the  two  little  flaps  that  are  called  balancers 
and  which  are  probably  remnants  of  hind  wings  which  the  remote  ances- 
tors of  flies  flew  with.  The  fly’s  wing  is  a transparent  but  strong  mem- 
brane strengthened  by  veins,  and  is  prettily  iridescent.  The  thorax 
bears  on  its  lower  side  the  three  pairs  of  legs.  The  abdomen  consists  of  five 
segments  and  is  covered  with  stiff  hairs.  The  parts  of  the  leg,  seen  when 
the  fly  is  walking,  consists  of  three  segments,  the  last  segment  or  tarsus 
being  more  slender,  and  if  looked  at  with  a lens,  is  seen  to  be  composed 
of  five  segments,  the  last  of  which  bears  the  claws;  it  is  with  these  claws 
that  the  fly  walks,  although  all  of  the,. five  segments  really  form  the  foot; 
in  other  words,  it  walks  on  its  tip-toes.  But  it  clings  to  ceilings  by  means 
of  the  two  little  pads  below  the  claws,  which  are  covered  with  hairs  that 
excrete  at  the  tips,  a sticky  fluid.  Because  of  the  hairs  on  its  feet,  the  fly 
becomes  a carrier  of  microbes  and  a menace  to  health. 

The  greatest  grudge  I have  against  this  little,  persistent  companion  of 
our  household  is  the  way  it  has  misled  us  by  appearing  to  be  so  fastidious 
in  its  personal  habits.  We  have  all  of  us  seen,  with  curiosity  and  admira- 
tion, its  complex  ablutions  and  brushings.  It  usually  begins,  logically, 
with  its  front  feet,  the  hands;  these  it  cleans  by  rubbing  them  against 
each  other  lengthwise.  The  hairs  and  spines  on  one  leg  act  as  a brush  for 
the  other,  and  then  lest  they  be  not  clean,  it  nibbles  them  with  its  rasping 
disc,  which  is  all  the  teeth  it  has.  It  then  cleans  its  head  with  these  clean 
hands,  rubbing  them  over  its  big  eyes  with  a vigor 
that  makes  us  wink  simply  to  contemplate ; then  bob- 
bing its  head  down  so  as  to  reach  what  is  literally  its 
back  hair,  it  brushes  valiantly.  After  this  is  done,  it 
reaches  forward  first  one  and  then  the  other  foot  of  the 
middle  pair  of  legs,  and  taking  each  in  turn  between  Foot  0f  house-fly 
the  front  feet,  brushes  it  vigorously,  and  maybe  enlarged.

nibbles  it.  But  as  a pair  of  military  brushes,  its  hind  feet  are 
conspicuously  efficient ; they  clean  each  other  by  being  rubbed  together 
and  then  they  work  simultaneously  on  each  side  in  cleaning  the  wings, 
first  the  under  side  and  then  the  upper  side.  Then  over  they  come  and 
comb  the  top  of  the  thorax;  then  they  brush  the  sides,  top  and  under 
sides  of  the  abdomen,  cleaning  each  other  between  the  acts.  Who,  after 
witnessing  all  this,  could  believe  that  the  fly  could  leave  any  tracks  on  our 
food,  which  would  lead  to  our  undoing!  But  the  house-fly,  like  many 
housekeepers  with  the  best  intentions  in  the  matter  of  keeping  clean,  has 
not  mastered  the  art  of  getting  rid  of  the  microbes.  Although  it  has  so 
many  little  eyes,  none  of  them  can  magnify  a germ  so  as  to  make  it  visible; 
and  thus  it  is  that,  when  feeding  around  where  there  have  been  cases  of 
typhoid  and  other  enteric  diseases,  the  house-fly’s  little  claws  become 
infested  with  disease  germs ; and  when  it  stops  some  day  to  clean  up  on  our 
table,  it  leaves  the  germs  with  us.  Thus  our  only  safety  lies  in  the 
final  extermination  of  this  little  nuisance. 

It  is  astonishing  how  few  people  know  about  the  growth  of  flies. 
People  of  the  highest  intelligence  in  other  matters,  think  that  a small  fly 
can  grow  into  a large  one.  A fly,  when  it  comes  from  the 
pupa  stage, Js  as  large  as  it  will  ever  be,  the  young  stages 
of  flies  being  maggots.  The  house-fly’s  eggs  are  little, 
white,  elongated  bodies  about  as  large  as  the  point  of  a 
pin.  These  are  laid  preferably  in  horse  manure.  After 
a few  hours,  they  hatch  into  slender,  pointed,  white 
maggots  which  feed  upon  the  excrement.  After  five  or 
six  days,  the  larval  skin  thickens,  turns  brown,  making 
the  insect  look  like  a small  grain  of  wheat.  This,  is  the 
pupal  stage,  which  lasts  about  fivc,.days,  and  then  the  skin 
bursts  open  and  the  full-grown  fly  appears.  Of  course, 
not  all  the  flies  multiply  according  to  the  example  given  to  the  children. 
The  house-fly  has  many  enemies  and,  therefore,  probably  no  one  hiber- 
nating mother  fly  is  the  ancestress  of  billions  by  September;  however, 
despite  enemies,  flies  multiply  with  great  rapidity. 

I know  of  no  more  convincing  experiment  as  an  example  of  the  dan- 
gerous trail  of  the  fly,  than  that  of  letting  a house-fly  walk  over  a saucer 
of  nutrient  gelatin.  After  three  or  four  days,  each  track  is  plainly  visible 
as  a little  white  growth  of  bacteria. 

Much  is  being  done  now  to  eradicate  the  house-fly,  and  undoubtedly 
there  will  be  new  methods  of  fighting  it  devised  every  year.  The  teacher 
should  keep  in  touch  with  the  bulletins  on  this  subject  published  by  the 
United  States  Department  of  Agriculture,  and  should  give  the  pupils 
instructions  according  to  the  latest  ideas.  At  present  the  following  are 
the  methods  of  fighting  this  pest : Keep  the  stable  clean  and  place  the 

manure  under  cover.  All  of  the  windows  of  the  house  should  be  well 
screened.  All  the  flies  which  get  into  the  house  should  be  killed  by  using 
the  commercial  fly  papers.

LESSON  XCI 
The  House-fly 

Leading  thought — The  house-fly  has  conquered  the  world  and  is  found 
everywhere.  It  breeds  in  filth  and  especially  in  horse  manure.  It  is  very 
prolific;  the  few  flies  that  manage  to  pass  the  winter  in  this  northern 
climate,  are  ancestors  of  the  millions  which  attack  us  and  our  food  later 
in  the  season.  These  are  a menace  to  health  because  they  carry  germs  of 
disease  from  sputa  and  excrementitious  matter  to  our  tables,  leaving  them 
upon  our  food. 

Method — Give  out  the  questions  for  observation  and  let  the  pupils 
answer  them  either  orally  or  in  their  note-books.  If  possible,  every  pupil 
should  look  at  a house-fly  through  a three-quarters  objective.  If  this  is 
not  possible,  pictures  should  be  shown  to  demonstrate  its  appearance. 

Observations — i . Look  at  a fly,  using  a lens  if  you  have  one.  Describe 
its  eyes.  Do  you  see  that  they  have  a honeycomb  arrangement  of  little 
eyes?  Can  you  see,  on  top  of  the  head  between  the  big  eyes,  a dot?  A 
microscope  reveals  this  dot  to  be  made  of  three  tiny  eyes,  huddled  to- 
gether. After  seeing  a fly’s  eyes,  do  you  wonder  that  you  have  so  much 
difficulty  in  hitting  it  or  catching  it? 

2.  Can  you  see  the  fly’s  antennae?  Do  you  think  that  it  has  a keen 
sense  of  smell  ? Why  ? 

3.  How  many  wings  has  the  fly?  How  does  it  differ  from  the  bee  in 
this  respect?  Can  you  see  two  little  white  objects,  one  just  behind  the 
base  of  each  wing?  These  are  called  poisers,  or  balancers,  and  all  flies  have 
them  in  some  form.  What  is  the  color  of  the  wings?  Are  they  trans- 
parent? Can  you  see  the  veins  in  them?  On  what  part  of  the  body  do 
the  wings  grow? 

4.  Look  at  the  fly  from  below.  How  many  legs  has  it?  From  what 
part  of  the  body  do  the  legs  come?  What  is  that  part  of  the  insect’s  body 
called,  to  which  the  legs  and  wings  are  attached? 

5.  How  does  the  fly’s  abdomen  look?  What  is  its  color  and  its 
covering? 

6.  Look  at  the  fly’s  legs.  How  many  segments  can  you  see  in  a leg? 
Can  you  see  that  the  segment  on  which  the  fly  walks  has  several  joints? 
Does  it  walk  on  all  of  these  segments  or  on  the  one  at  the  tip? 

7 . When  the  fly  eats,  can  you  see  its  tongue  ? Can  you  feel  its  tongue 
when  it  rasps  your  hand?  Where  does  it  keep  its  tongue  usually? 

8.  Describe  how  a fly  makes  its  toilet  as  follows:  How  does  it  clean 

its  front  feet?  Its  head?  Its  middle  feet?  Its  hind  feet?  Its  wings? 

9.  Do  you  know  how  flies  carry  disease?  Did  you  ever  see  them 
making  their  toilet  on  your  food  at  the  table?  Do  you  know  what 
diseases  are  carried  by  flies?  What  must  you  do  to  prevent  flies  from 
bringing  disease  to  your  family  ? 

10.  Do  you  think  that  a small  fly  ever  grows  to  be  a large  fly?  How 
do  the  young  of  all  kinds  of  flies  look?  Do  you  know  where  the  house-fly 
lays  its  eggs?  On  what  do  the  maggots  feed?  How  long  before  they 
change  to  pupae?  How  long  does  it  take  them  to  grow  from  eggs  to  flies? 
How  do  the  house-flies  in  our  northern  climate  pass  the  winter? 

11.  Lesson  in  Arithmetic — It  requires  perhaps  twenty  days  to  span 
the  time  from  the  eggs  of  one  generation  of  the  house-fly  to  the  eggs  of 
the  next,  and  thus  there  might  easily  be  five  generations  in  one  summer.

Supposing  the  fly  which  wintered  behind  the  window  curtain  in  your  home 
last  winter,  flew  out  to  the  stables  about  May  1st  and  laid  120  eggs  in  the 
sweepings  from  the  horse  stable,  all  of  which  hatched  and  matured. 
Supposing  one-half  of  these  were  mother  flies  and  each  of  them,  in  turn, 
laid  120  eggs,  and  so  on  for  five  generations,  all  eggs  laid  developing  into 
flies,  and  one-half  of  the  flies  of  each  generation  being  mother  flies.  How 
many  flies  would  the  fly  that  wintered  behind  your  curtain  have  pro- 
duced by  September? 

12.  Pour  some  gelatin  unsweetened,  on  a clean  plate.  Let  a house- 
fly walk  around  on  the  gelatin  as  soon  as  it  is  cool ; cover  the  plate  to  keep 
out  the  dust  and  leave  it  for  two  or  three  days.  Examine  it  then  and  see 
if  you  can  tell  where  the  fly  walked.  What  did  it  leave  in  its  tracks? 

13.  Write  an  essay  on  the  house-fly,  its  dangers  and  how  to  combat  it, 
basing  the  essay  on  Bulletins  of  the  U.  S..  Department  of  Agriculture. 

THE  COLORADO  POTATO-BEETLE 
Teacher's  Story 

HE  potato-beetle  is  not  a very  attractive  insect, 
but  it  has  many  interesting  peculiarities.  No 
other  common  insect  so  clearly  illustrates  the 
advantage  of  warning  colors.  If  we  take  a 
beetle  in  the  hand,  it  at  first  promptly  falls 
upon  its  back,  folds  its  legs,  and  antennae  down 
close  to  its  body,  and  “plays  possum”  in  a very 
canny  manner.  But  if  we  squeeze  it  a little, 
immediately  an  orange-red  liquid  is  ejected  on 
the  hand,  and  a very  ill-smelling  liquid  it  is. 
If  we  press  lightly,  only  a little  of  the  secretion 
is  thrown  off;  but  if  we  squeeze  harder  it 
flows  copiously.  Thus  a bird  trying  to  swallow  one  of  these  beetles,  would 
surely  get  a large  dose.  The  liquid  is  very  distasteful  to  birds,  and  it  is 
indeed  a stupid  bird  that  does  not  soon  learn  to  let  severely  alone  orange 
and  yellow  beetles,  striped  with  black.  The  source  of  this  offensive  and 
defensive  juice  is  at  first  a mystery,  but  if  we  observe  closely  we  can  see  it 
issuing  along  the  hind  edge  of  the  thorax  and  the  front  portion  of  the 
WjLng-covers ; the  glands  in  these  situations  secrete  the  protective  juice  as 
it  is  needed.  The  larvae  are  also  equipped  with  similar  glands  and,  there- 
f ore,;  have  the  brazen  habit  of  eating  the  leaves  of  our  precious  potatoes 
without  attempting  to  hide.  They  seem  to  know  that  they  are  far  safer 
when  seen  by  birds  than  when  concealed  from  them. 

The  life  history  of  the  potato-beetle  is  briefly  as  follows:  Some 
of  the  adult  beetles  or  pupae  winter  beneath  the  surface  of  the  soil, 
burrowing  down  a foot  or  more  to  escape  freezing.  As  soon  as  the  potato 
plants  appear  above  ground  the  mother  beetle  comes  out  and  lays  her  eggs 
upon  the  under  sides  of  the  leaves.  These  orange-yellow  eggs  are 
usually  laid  in  clusters.  In  about  a week  there  hatches  from  the  eggs 
little  yellow  or  orange  humpbacked  larvae,  which  begin  at  once  to  feed 
upon  the  leaves.  These  larvae  grow  as  do  other  insects,  by  shedding

their  skins.  They  do  this  four  times,  and  during  the  last  stages,  are 
very  conspicuous  insects  on  the  green  leaves; 
they  are  orange  or  yellow  with  black  dots 
along  the  sides,  and  so  humpbacked  are  they 
that  they  seem  to  be  “gathered  with  a pucker- 
ing string”  along  the  lower  side.  It  requires 
from  sixteen  days  to  three  weeks  for  a larva 
to  completje  its  growth.  It  then  descends  into 
the  earth  and  forms  a little  cell  in  which  it 
changes  to  a pupa.  It  remains  in  this  con- 
dition for  one  or  two  weeks,  according  to  the 
temperature,  and  then  the  full-fledged  beetle 
appears.  The  entire  life  cycle  from  egg  to 
adult  beetle  may  be  passed  in  about  a 
month,  although  if  the  weather  is  cold,  this 
period  will  be  longer.  The  beetles  are  very 
prolific,  a mother  beetle  having  been  known 
to  produce  five  hundred  eggs,  and  there  are 
two  generations  each  year.  These  beetles 
not  only  damage  the  potato  crop  by  stopping 
the  growth  through  destroying  the  leaves,  but  they  also  cause  the 
potatoes  to  be  of  inferior  quality. 

The  adult  beetle  is  an  excellent 
object  lesson  in  the  study  of  beetle 
form.  Attention  should  be  called 
to  the  three  regions  of  the  body:  A 
head  which  is  bright  orange;  the 
compound  eyes,  which  are  black; 
and  three  simple  eyes  on  the  top 
of  the  head,  which  are  difficult  to 
see  without  a lens.  The  antennae 
are  short,  their  joints  easily  noted, 
and  special  attention  should  be  paid 
to  their  use,  for  they  are  constantly 
moving  to  feel  approaching  objects. 

The  two  pairs  of  mouth  palpi  may 
be  seen,  and  the  beetle  will  eagerly 
eat  raw  potatoes,  so  that  the  pupils 
may  see  that  it  has  biting  mouth- 
parts.  The  thoracic  shield  is 
orange,  ornamented  with  black. 

The  three  pairs  of  legs  are  short, 
which  is  a proof  that  these  beetles 
do  not  migrate  on  foot.  The  claws 
and  the  pads  beneath  can  be  seen 
with  the  naked  eye.  Each  wing- 
cover  bears  five  yellow  stripes,  also  five  black  ones,  although  the  outside 
black  stripe  is  rather  narrow.  These  beetles  are  very  successful  flyers. 
During  flight,  the  wing-covers  are  raised  and  held  motionless  while  the 
gauzy  wings  beneath  are  unfolded  and  do  the  work.  Children  are 
always  interested  in  seeing  the  way  the  beetles  fold  their  wings 
beneath  the  wing-covers.

One  of  the  most  remarkable  things  about  the  Colorado  potato-beetle 
is  its  history.  It  is  one  of  the  few  insect  pests  which  is  native  to  America. 
It  formerly  fed  upon  sandbur,  a wild  plant  allied  to  the  potato,  which 
grows  in  the  region  of  Colorado,  Arizona  and 
Mexico,  and  was  a well  behaved,  harmless  in- 
sect. With  the  advance  of  civilization  west- 
ward, the  potato  came  also,  and  proved  to  be 
an  acceptable  plant  to  this  insect;  and  here 
we  have  an  example  of  what  an  unlimited 
food  supply  will  do  for  an  insect  species.  The 
beetles  multiplied  so  much  faster  than  their 
parasites,  that  it  seemed  at  one  time  as  if  they 
would  conquer  the  earth  by  moving  on  from 
potato  field  to  potato  field.  They  started  on 
their  march  to  the  Atlantic  seaboard  in  1859; 
in  1874,  they  reached  the  coast  and  judging  by 
the  numbers  washed  ashore,  they  sought  to  fly 
or  swim  across  the  Atlantic.  By  1879,  they 
had  spread  over  an  area  consisting  of  more 
than  one-third  of  the  United  States.

LESSON  XCII 

The  Colorado  Potato-beetle 

Leading  thought — The  Colorado  potato-beetle  is  a very  important 
insect,  since  it  affects  the  price  of  potatoes  each  year.  It  is  disagreeable 
as  a food  for  birds,  because  of  an  acrid  juice  which  it  secretes.  We  should 
learn  its  life-history  and  thus  be  able  to  deal  with  it  intelligently  in  pre- 
venting its  ravages. 

Method — The  study  of  the  potato-beetle  naturally  follows  and  belongs 
to  gardening.  The  larvae  should  be  brought  into  the  schoolroom  and 
placed  in  a breeding  cage  on  leaves  of  the  potato  vine.  Other  plants  may 
be  put  into  the  cage  to  prove  that  these  insects  will  only  eat  the  potato. 
The  children  should  observe  how  the  larvae  eat  and  how  many  leaves  a 
full  grown  larva  will  destroy  in  a day.  Earth  should  be  put  in  the  bottom 
of  the  breeding  cage  so  that  the  children  may  see  the  larvae  descend  and 
burrow  into  it.  The  adult  beetles  should  be  studied  carefully,  and  espe- 
cially, the  children  should  see  the  excretion  of  the  acrid  juice. 

Observations — 1.  At  what  time  do  you  see  the  potato-beetles?  Why 
are  they  more  numerous  in  the  fall  than  in  the  spring?  Where  do  those 
which  we  find  in  the  spring  come  from?  What  will  they  do  if  they  are 
allowed  to  live  ? 

2.  What  is  the  shape  of  the  potato-beetle?  Describe  the  markings 
on  its  head.  What  color  are  its  eyes?  Describe  its  antennae.  How  are 
they  constantly  used?  Can  you  see  the  palpi  of  the  mouth?  Give  the 
beetle  a bit  of  potato  and  note  how  it  eats. 

3.  What  is  the  color  of  the  shield  of  the  thorax?  Describe  the  legs.  - 
Do  you  think  the  beetle  can  run  fast?  Why  not?  How  many  segments 
has  the  foot  ? Describe  the  claws.  Describe  how  it  clings  to  the  sides  of 
a tumbler  or  bottle.

4.  If  the  beetle  cannot  run  rapidly,  how  does  it  travel?  Describe  the 
wing-covers.  Why  is  this  insect  called  the  ten-lined  potato  beetle? 

5 . Describe  the  wings.  How  are  they  folded  when  at  rest  ? How  are 
the  wing-covers  carried  when  the  beetle  is  flying? 

6.  Take  a beetle  in  your  hand.  What  does  it  do?  Of  what  advan- 
tage is  it  to  ihe  insect  to  pretend  that  it  is  dead?  If  you  squeeze  the 
beetle  what  happens?  How  does  the  fluid  which  it  ejects  look  and  smell? 
Try  and  discover  where  this  fluid  comes  from?  Of  what  use  is  it  to  the 
beetle  ? Why  will  birds  not  eat  the  potato-beetle  ? 

7 . Where  does  the  mother  beetle  lay  her  eggs  ? Are  they  laid  singly 
or  in  clusters?  What  color  are  the  eggs?  How  long  after  they  are  laid 
before  they  hatch  ? 

8.  Describe  the  young  larva  when  it  first  hatches.  What  color  is  it  at 
first?  Does  it  change  color  later?  Describe  the  colors  and  markings  of  a 
full  grown  larva. 

9.  How  does  this  larva  injure  the  potato  vines?  Does  it  remain  in 
sight  while  it  is  feeding?  Does  it  act  as  if  it  were  afraid  of  birds ? Why 
is  it  not  eaten  by  bi-rds? 

10.  Where  does  the  larva  go  when  it  is  full  grown  ? How  many  times 
does  it  shed  its  skin  during  its  growth  ? Does  it  make  a little  cell  in  the 
ground  ? How  does  the  pupa  look  ? Can  you  see  in  it  the  eyes,  antennae, 
legs  and  wings  of  the  beetle  ? 

11.  Write  an  English  theme  giving  the  history  of  the  Colorado 
potato-beetle,  and  the  reasons  for  its  migration  from  its  native  place.

THE  LADYBIRD 
Teacher's  Story 

Ladybird,  Ladybird,  fly  away  home! 

Your  house  is  on  fire,  your  children  are  burning. 

HIS  incantation  we,  as  children,  repeated  to  this 
unhearing  little  beetle,  probably  because  she  is 
and  ever  has  been,  the  incarnation  of  energetic 
indecision.  She  runs  as  fast  as  her  short  legs  can 
carry  her  in  one  direction,  as  if  her  life  depended  on 
getting  there,  then  she  turns  about  and  goes  with 
quite  as  much  vim  in  another  direction.  Thus,  it 
is  no  wonder  the  children  think  that  when  she 

hears  this  news  of  her  domestic  disasters,  she 

wheels  about  and  starts  for  home;  but  she  has  not 
any  home  now  nor  did  she  ever  have  a home,  and  she  does  not  carry  even  a 
trunk.  Perhaps  it  would  be  truer  to  say  that  she  has  a home  everywhere, 
whether  she  is  cuddled  under  a leaf  for  a night’s  lodging  or  industriously 
climbing  out  on  twigs,  only  to  scramble  back  again,  or  perchance  to  take 
flight  from  their  tips. 

There  are  many  species  of  ladybirds,  but  in  general  they  all  resemble 
a tiny  pill  cut  in  half,  with  legs  attached  to  the  flat  side.  Sometimes  it 
may  be  a round  and  sometimes  an  oval  pill,  but  it  is  always  shining  and 
the  colors  are  always  dull  dark  red,  or  yellow,  or  whit- 
ish, and  black.  Sometimes  she  is  black  with  red  or 
yellow  spots,  sometimes  red  or  yellow  with  black  spots 
and  the  spots  are  usually  on  either  side  of  the  thorax 
and  one  on  each  snug  little  wing-cover.  But  if  we 
look  at  the  ladybird  carefully  we  can  see  the  head  and  the  short,  clublike 
antennae.  Behind  the  head  is  the  thorax  with  its  shield,  broadening 
toward  the  rear,  spotted  and  ornamented  in  various  ways ; the  head  and 
thorax  together  occupy  scarcely  a fourth  of  the  length  of  the  insect,  and 
the  remainder  consists  of  the  hemispherical  body,  encased  with  polished 
wing-covers.  The  little  black  legs,  while  quite  efficient  because  they  can 
be  moved  so  rapidly,  are  not  the  ladybird’s  only  means  of  locomotion; 
she  is  a good  flier  and  has  a long  pair  of  dark  wings  which  she  folds  cross- 
wise under  her  wing-covers.  It  is  comical  to  see  her  pull  up  her  wings,  as 
a lady  tucks  up  a long  petticoat;  and  sometimes  ladybrd  is  rather 
slovenly  about  it  and  runs  around  with  the  tips  of  her  wings  hanging  out 
behind,  quite  untidily. 

But  any  untidiness  must  be  inadvertent,  because  the  ladybird  takes 
very  good  care  of  herself  and  spends  much  time  in  “washing  up.”  She 
begins  with  her  front  legs,  cleaning  them  with  her  mandibles,  industriously 
nibbling  off  every  grain  of  dust ; she  then  cleans  her  middle  and  hind  legs 
by  rubbing  the  two  on  the  same  side,  back  and  forth  against  each  other, 
each  acting  as  a whisk  broom  for  the  other;  she  cleans  her  wings  by 
brushing  them  between  the  edges  of  the  wing-cover  above  and  the  tarsus 
of  her  hind  leg  below. 

The  ladybird  is  a clever  little  creature,  even  if  it  does  look  like  a pill, 
and  if  you  disturb  it,  it  will  fold  up  its  legs  and  drop  as  if  dead,  playing 
possum  in  a most  deceptive  manner.  It  will  remain  in  this  attitude  of 


Ladybird  larva.

rigid  death  for  at  least  a minute  or  two  and  then  will  begin  to  claw  the  aii 
with  all  its  six  legs  in  an  effort  to  turn  right  side  up. 

From  our  standpoint  the  ladybird  is  of  great  value,  for  during  the 
larval  as  well  as  adult  stages,  all  species  except  one,  feed  upon  those 
insects  which  we  are  glad  to  be  rid  of.  They  are  especially  fond  of  aphids 
and  scale  insects.  One  of  the  greatest  achievements  of  economic  entomol- 
ogy was  the  introduction  on  the  Pacific  Coast  of  the  ladybird  from 
Australia,  called  the  Vedalia,  which  preys  upon  the  cottony  cushion 
scale  insect,  a species  very  dangerous  to  orange  and  lemon  trees.  Within 
a few  years  the  introduced  ladybirds  had  completely  exterminated  this 
pest. 

The  ladybird’s  history  is  as  follows : The  mother  beetle,  in  the  spring, 

lays  her  eggs  here  and  there  on  plants : as  soon  as  the  larva  hatches,  it 
starts  out  to  hunt  for  aphids  and  other  insects.  It  is  safe  to  say  that  no 
ladybird  would  recognize  her  own  children  in  time  to  save 
them,  even  if  the  house  were  burning,  for  they  do  not  in  the 
least  resemble  her;  they  are  neither  roly-poly  nor  shiny,  but 
are  long  and  segmented  and  velvety,  with  six  queer,  short  legs 
that  look  and  act  as  if  they  were  whittled  out  of  wood ; they 
seem  only  efficient  for  clinging  around  a stem  The  larvae  are 
usually  black,  spotted  with  orange  or  yellow;  there  are  six 
warts  on  each  segment,  which  make  the  creature’s  back  look 
quite  rough.  The  absorbing  business  of  the  larva  is  to  crawl 
around  on  plants  and  chew  up  the  foolish  aphids  or  the  scale 
have  seen  one  use  its  front  foot  to  push  an  aphid,  which  it  was 
eating,  closer  to  its  jaws;  but  when  one  green  leg  of  its  victim  still  clung 
to  its  head,  it  did  not  try  to  rub  it  off  as  its  mother  would  have  done,  but 
twisted  its  head  over  this  way  and  that,  wiping  off  the  fragment  on  a plant 
stem  and  then  gobbling  it  up. 

After  the  larva  has  shed  its  skeleton  skin  several  times,  and  destroyed 
many  times  its  own  bulk  of  insects,  it  hunts  for  some  quiet  corner,  hangs 
itself  up  by  the  tail  and  condenses  itself  into  a sub -globular  form ; 
it  sheds  its  spiny  skin  pushing  it  up  around  the  point  of  attach- 
ment, and  there  lets  it  stay  like  the  lion’s  skin  of  Hercules.  As  a 
pupa,  it  is  more  nearly  rectangular  than  round,  and  if  we  look 
closely,  we  can  see  the  wing-cases,  the  spotted  segments  of  th 
abdomen,  and  the  eyes,  all  encased  in  the  pupa  skin;  the  latter  <‘the  ’ 
bursts  open  after  a few  days  and  the  shining,  little  half-globe  nine- 
emerges  a full-grown  ladybird,  ready  for  hiding  in  some  cozy  spot  spotted 
to  pass  the  winter,  from  which  she  will  emerge  in  the  spring,  to 
stock  our  trees  and  vines,  next  year,  with  her  busy  little  progeny.  u^'

LESSON  XCIII 
The  Ladybird 

Leading  thought — The  ladybird  is  a beetle.  Its  young  are  very  differ- 
ent from  the  adult  in  appearance,  and  feed  upon  plant -lice. 

Method — These  little  beetles  are  very  common  in  autumn  and  may  be 
brought  to  the  schoolroom  and  passed  around  in  vials  for  the  children  to 
observe.  Their  larvae  may  be  found  on  almost  any  plant  infested  with 


Insect  Study 


415 


plant-lice.  Plant  and  all  may  be  brought  into  the  schoolroom  and  the 
actions  of  the  larvae  noted  by  the  pupils  during  recess. 

Observations — 1.  How  large  is  the  ladybird?  What  is  its  shape? 
Would  two  of  them  make  a little  globe  if  they  were  put  flat  sides  together? 

2 . What  colors  do  you  find  on  your  ladybird  ? 

3.  Do  you  see  the  ladybird’s  head  and  antennae?  What  is7 the  broad 
shield  directly  back  of  the  head  called  ? How  is  it  marked,  and  with  what 
colors?  What  color  are  the  wing-covers?  Are  there  any  spots  upon 
them?  How  many?  Does  the  ladybird  use  its  wing-covers  when  it  flies? 
Describe  her  true  wings.  Does  she  fold  them  beneath  the  wing-covers? 

4.  Note  the  legs  and  feet.  Are  the  legs  long?  Are  they  fitted  for 
running?  To  which  part  of  the  body  are  they  attached? 

5 . If  you  disturb  the  ladybird  how  does  she  “ play  possum  ? ’ ’ Describe 
how  she  makes  her  toilet. 

The  larva — 1.  Describe  the  ladybird  larva.  Does  it  look  like  its 
mother?  What  is  its  form?  Is  it  warty  and  velvety  or  shiny ? 

2.  Describe  its  head  and  jaws  as  far  as  you  can  see.  How  does  it  act 
when  eating?  Can  you  see  its  little  stiff  legs?  Is  there  a claw  at  the  end 
of  each? 

3 . Describe  the  actions  of  the  ladybird  larva  in  attacking  and  eating 
the  plant-lice.  Does  it  shed  its  skin  as  it  grows  ? 

4.  Watch  a larva  until  it  changes  to  a pupa.  How  does  the  pupa 
look?  Can  you  see  the  shed  skin?  Where  is  it?  To  what  is  the  pupa 
attached  ? When  the  pupa  skin  breaks  open  what  comes  out  of  it  ? 

5.  Why  is  the  ladybird  of  great  use  to  us  ? Write  an  English  theme 
upon  the  ladybird,  called  Vedalia,  which  saved  the  orange  orchards  of 
California.

THE  FIREFLY 

Teacher's  Story 

And  lavishly  to  left  and  right. 

The  fireflies,  like  golden  seeds, 

Are  sown  upon  the  night. 

— Riley. 

I time  of  this  sowing  is  during  warm,  damp  nights  in 
July  and  August,  and  even  in  September,  although 
they  are  sown  less  lavishly  then.  How  little  most  of 
us  know  of  the  harvest,  although  we  see  the  sowing 
which  begins  in  the  early  twilight  against  the  back- 
ground of  tree  shadows,  and  lasts  until  the  cold 
atmosphere  of  the  later  night  dampens  the  firefly 
ardor!  There  is  a difference  in  species  as  to  the 
height  from  the  ground  of  their  flight ; some  species 
hover  next  to  the  grass,  others  fly  above  our  heads, 
but  rarely  as  high  as  the  tree  tops  in  northern  latitudes.  Some  species 
give  a short  flash  that  might  be  called  a refulgent  blinking ; others  give  a 
longer  flash  so  that  we  get  an  idea  of  the  direction  of  their  flight;  and 
there  is  a common  species  in  the  Gulf  States  which  gives  such  long  flashes 
that  they  mark  the  night  with  gleaming  curlicues. 

It  is  likely  to  be  an  exciting  chase,  before  we  are  able  to  capture  a few 
of  these  insects  for  closer  inspection;  but  when  once  captured,  they  do 
not  sulk  but  will  keep  on  with  their  flashing  and  give  us  a most  edifying 
display.  The  portion  of  the  firefly  which  gives  the  light  is  in  the  abdomen, 
and  it  glows  steadily  like  “phosphorescent  wood”;  then  suddenly  it 
gleams  with  a green  light  that  is  strong  enough  to  reveal  all  its  sur- 
roundings ; and  it  is  so  evidently  an  act  of  will  on  the  part  of  the  beetle, 
that  it  is  startling  to  members  of  our  race,  who  cannot  even  blush  or 
turn  pale  voluntarily.  The  fireflies  may  be  truly  said  to  be  socially  bril- 
liant, for  the  flashing  of  their  lights  is  for  the  attraction  of  their  mates. 

The  fireflies  are  beetles,  and  there  are  many 
species  which  are  luminous.  A common  one  is  here 
figured  ( Photinus  pyralis ) . It  is  pale  gray  above 

and  the  head  is  completely  hidden  by  the  big  shield 
of  the  thorax.  The  legs  are  short;  thus  this  beetle 
trusts  mostly  to  its  wings  as  a means  of  locomotion. 

The  antennae  are  rather  long  and  are  kept  in 
constant  motion,  evidently  conveying  intelligence 
of  surroundings  to  the  insect.  Beneath  the  gray 
elytra,  or  wing-covers,  is  a pair  of  large,  dark- 
veined  membranous  wings  which  are  folded  in  a 
very  neat  manner  crosswise  and  lengthwise, 
when  not  in  use.  When  in  use,  the  wing-covers  are  lifted  stiffly 
and  the  flying  is  done  wholly  with  the  membranous  wings.  Looked 
at  from  beneath,  we  can  at  once  see  that  some  of  the  segments  of  the 
abdomen  are  partly  or  entirely  sulphur  yellow,  and  we  recognize  them  as 
the  lamp.  If  the  specimen  is  a male,  the  yellow  area  covers  all  of  the  end 
of  the  abdomen  up  to  the  fourth  or  fifth  segment ; but  if  it  is  a female, 
only  the  middle  portion  of  the  abdomen,  especially  the  fifth  segment,  is 
converted  into  a lamp.  These  yellow  areas,  when  dissected  under  the

view  of  the  lower 
side  shows  the 
“lamp.” 


Insect  Study 


417 


microscope,  prove  to  be  filled  with  fine  tracheae,  or  air-tubes ; and  although 
we  know  very  little  about  the  way  the  light  is  made,  it  is  believed  that  by 
flooding  the  tubes  with  air,  the  oxygen  in  some  way  produces  the 
light. 

In  some  species,  the  female  is  wingless  and  has  very  short  wing- 
covers,  and  a portion  of  her  body  emits  a steady,  greenish  light  which  tells 
her  lord  and  master  where  to  find  her.  These  wingless  females  are  called 


glow-worms. 

Fireflies  during  their  larval  stages  are  popularly  called  wire  worms, 
although  there  are  many  other  beetle  larvae  thus  called.  In  many  of  the 
species,  the  firefly  eggs,  larvae  and  pupae  are  all  luminescent,  but  not  so 
brilliant  as  when  adults.  The  larva  of  the  species  here  figured,  was 
studied  by  C.  V.  Riley,  who  gave  us  an  interesting  account  of  its  habits. 

It  lives  in  the  ground  and  feeds  on  soft-bodied 
insects,  probably  earth-worms.  Each  segment  of  this 
wire  worm  has  a horny,  brown  plate  above,  with  a 
straight  white  line  running  through  the  middle  and 
a slightly  curved  white  line  on  each  side ; the  sides 
of  the  larva  are  soft  and  rose-colored;  the  white 
spiracles  show  against  little,  oval,  brown  patches. 
Beneath,  the  larva  is  cream  color  with  two  brown 
comma-lilce  dots  at  the  center  of  each  segment. 
The  head  can  be  pulled  back  completely  beneath  the 
first  segment.  The  most  interesting  thing  about  this 
larva  is  the  prop-leg  at  the  end  of  its  body,  which 
t j „ r naturally  aids  it  in  locomotion ; but  this  prop-leg  also 

rnmmnu .firefiv.  functions  as  a brush ; after  the  larva  has  become 

soiled  with  too  eager  delving  into  the  tissues  of  some 
earthworm,  it  curls  its  body  over,  and  with  this  fan- 
shaped hind  foot  scrubs  its  head  and  face  very  clean.  This  is  a rare 
instance  of  a larva  paying  any  attention  to  its  toilet. 

When  full-grown,  the  larva  makes  a little  oval  cell  within  the  earth  and 
changes  to  a pupa ; after  about  ten  days,  the  pupa  skin  is  shed  and  the 
full-fledged  beetle  comes  forth.  The  larva  and  pupa  of  this  species  give 
off  light,  but  are  not  so  brilliant  as  the  adult.  The  pupils  should  be  en- 
couraged to  study  the  early  stages  of  the  fireflies,  because  very  little  is 
known  concerning  them. 

In  Cuba  a large  beetle  called  the  cucujo  has  two  great  oval  spots  on  its 
thorax,  resembling  eyes,  which  give  off  light.  The  Cuban  ladies  wear 
cucujos  at  the  opera,  in  nets,  in  the  hair.  I once  had  a pair  which  I 
tethered  with  gold  chains  to  the  bodice  of  my  ball  gown.  The  eye-spots 
glowed  steadily,  but  with  the  movement  of  dancing,  they  grew  more  bril- 
liant until  no  glittering  diamonds  could  compete  with  their  glow.

LESSON  XCIV 
The  Firefly 

Leading  thought — When  the  firefly  wishes  to  make  a light,  it  can  pro- 
duce one  that,  if  we  knew  how  to  make,  would  greatly  reduce  the  price  of 
artificial  light;  for  the  light  made  by  fireflies  and  other  creatures, 
requires  less  energy  than  any  other  light  known. 

Method — -After  the  outdoor  observations  have  been  made,  collect  some 
of  these  beetles  in  the  evening  with  a sweep  net;  place  them  under  a 


4lS 


Handbook  of  Nature-Study 


glass  jar  or  tumbler,  so  that  their  light  can  be  studied  at  close  range. 
The  next  day  give  the  observation  lesson  on  the  insects. 

Observations — i.  At  what  time  of  year  do  you  see  fireflies?  Do  they 
begin  to  lighten  before  it  is  dark?  Do  you  see  them  high  in  the  air  or  near 
the  ground?  Is  the  flash  they  give  short,  or  long  enough  to  make  a 
streak  of  light?  Do  you  see  them  on  cold  and  windy  nights  or  on  warm, 
still,  damp  evenings?  Make  a note  of  the  hour  when  you  see  the  first  one 
flash  in  an  evening. 

2.  Catch  a few  fireflies  in  the  night ; put  them  under  a glass  jar.  Can 
you  see  the  light  when  they  are  not  flashing?  What  color  is  it?  When 
they  make  the  flash  can  you  see  the  outline  of  the  “firefly  lamp  ?”  Watch 
closely  and  see  if  you  think  the  flashing  is  a matter  of  will  on  the  part  of 
the  firefly.  Do  you  think  the  firefly  is  signaling  to  his  mate  when  he 
flashes? 

3.  Study  the  firefly  in  daylight.  Is  it  a fly  or  is  it  a beetle?  What 
color  is  it  above?  When  you  look  squarely  down  upon  it,  can  you  see  its 
head  and  eyes? 

4.  Are  the  firefly’s  legs  long  or  short?  When  a beetle  has  short  legs 
is  it  a sign  that  it  usually  walks,  runs  or  flies? 

5.  Describe  the  antennae.  Are  they  in  constant  motion?  What 
service  do  you  think  the  firefly’s  antennae  perform  for  it? 

6.  Lift  one  of  the  wing-covers  carefully.  What  do  you  find  beneath 
it?  Does  the  beetle  use  its  wing-covers  to  beat  the  air  and  help  it  during 
flight?  How  does  the  beetle  hold  its  wing-covers  when  flying? 

7.  Turn  the  beetle  on  its  back.  Can  you  see  the  part  of  the  body 
that  flashes?  What  color  is  it? 

8.  Do  you  know  the  life  history  of  the  firefly?  What  is  it  like  in  its 
earlier  stages?  Where  does  it  live?  Does  it  have  the  power  of  making 
light  when  it  is  in  the  larval  stage  ? 


“There,  in  warm  August  gloaming. 
With  quick  silent  brightenings, 

From  meadow-lands  roaming, 

The  firefly  twinkles 
His  fitful  heat-lightnings .”

THE  WAYS  OF  THE  ANT 

My  child,  behold  the  cheerful  ant. 

How  hard  she  works,  each  day; 

She  works  as  hard  as  adamant 
Which  is  very  hard , they  say. 

— Oliver  Herford. 

ERY  many  performances  on  the  part  of  the  ant  seem 
to  us  without  reason;  undoubtedly  many  of  our 
performances  seem  likewise  to  her.  But  the  more 
understanding! y we  study  her  and  her  ways,  the 
more  we  are  forced  to  the  conclusion  that  she 
knows  what  she  is  about ; I am  sure  that  none  of  us 
can  sit  down  by  an  ant-nest  and  watch  its  citizens 
come  and  go,  without  discovering  things  to  make 
us  marvel. 

By  far  the  greater  number  of  species  of  ants 
find  exit  from  their  underground  burrows,  beneath 
stones  in  fields.  They  like  the  stone  for  more 
reasons  than  one ; it  becomes  hot  under  the  noon  sun  and  remains  warm 
during  the  night,  thus  giving  them  a cozy  nursery  in  the  evening  for  their 
young.  Some  species  make  mounds,  and  often  several  neighboring 
mounds  belong  to  the  same  colony,  and  are  connected  by  underground 
galleries.  There  are  usually  several  openings  into  these  mounds.  In 
case  of  some  of  the  western  species  which  make  galleries  beneath  the 
ground,  there  is  but  one  opening  to  the  nest  and  Dr.  McCook  says  that 
this  gate  is  closed  at  night;  at  every  gate  in  any  ants’  nest,  there  are 
likely  to  be  sentinels  stationed,  to  give  warning  of  intruders. 

A',  soon  as  a nest  is  disturbed,  the  scared  little  citizens  run  helter 
skelter  to  get  out  of  the  way;  but  if  there  are  any  larvae  or  pupae  about, 
they  are  never  too  frightened  to  take  them  up  and  make  off  with  them ; 
but  when  too  hard  pressed,  they  will  in  most  cases  drop  the  precious 
burden,  although  I have  several  times  seen  an  ant,  when  she  dropped  a 
pupa,  stand  guard  over  it  and  refuse  to  budge  without  it.  The  ant’s  eggs 
are  very  small  objects,  being  oblong  and  about  the  size  of  a pin  point. 
The  larvae  are  translucent  creatures,  like  rice  grains  with  one  end  pointed. 
The  pupae  are  yellowish,  covered  with  a parchment-like  sac,  and  resemble 
grains  of  wheat.  When  we  lift  stones  in  a field,  we  usually  find  directly 
beneath,  the  young  of  a certain  size. 

There  are  often,  in  the  same  species  of  ants,  two  sizes ; the  large  ones 
are  called  majors  and  the  smaller  minors;  sometimes  there  is  a smaller 
size  yet,  called  minims.  The  smaller  sizes  are  probably  the  result  of  lack 
of  nutrition.  But  whatever  their  size,  they  all  work  together  to  bring 
food  for  the  young  and  in  caring  for  the  nest.  We  often  see  an  ant  carry- 
ing a dead  insect  or  some  other  object  larger  than  herself.  If  she  cannot 
lift  it  or  shove  it,  she  turns  around,  and  going  backwards,  pulls  it  along. 
It  is  rarely  that  we  see  two  carrying  the  same  load,  although  we  have 
observed  this  several  times.  In  one  or  two  cases,  the  two  seemed  not  to 
be  in  perfect  accord  as  to  which  path  to  take.  If  the  ants  find  some  large 
supp^  of  food,  many  of  them  will  form  a procession  to  bring  it  into  the 
nest  bit  by  bit ; such  processions  go  back  by  making  a little  detour  so  as

summer  the  uest  may  be  found  swarming  with  winged  forms  which  are 
the  kings  and  queens.  Some  warm  day  these  will  issue  from  the  nest 
and  take  their  marriage  flight,  the  only  time  in  their  lives  when  they  use 
their  wings;  for  ants,  like  seeds,  seem  to  be  provided  with  wings  simply 
for  the  sake  of  scattering  wide  the  species.  It  is  a strange  fact,  that  often 
on  the  same  day  swarms  will  issue  from  all  the  nests  of  one  species  in  the 
whole  region;  by  what  mysterious  messenger,  word  is  sent  that  brings 

about  this  unanimous  exodus,  is  still  a 
mystery  to  us.  This  seems  to  be  a provi- 
sion for  cross-breeding;  and  as  bearing  upon 
this,  Miss  Fielde  discovered  that  an  alien 
king  is  not  only  made  welcome  in  a nest,  but 
is  sometimes  seized  by  workers  and  pulled 
into  a nest;  this  is  most  significant,  since 
no  worker  of  any  other  colony  of  the  same 
species,  is  permitted  to  live  in  any  but  its 
own  nest. 

After  the  marriage  flight,  the  ants  fall 
to  the  ground  and  undoubtedly  a large 
number  perish;  however,  just  here  our 
knowledge  is  lamentably  lacking,  and 
observations  on  the  part  of  pupils  as  to 
what  happens  to  these  winged  forms  will  be 
valuable.  In  the  case  of  most  species,  we 
know  that  a queen  finds  refuge  in  some 
shelter  and  there  lays  eggs.  Mr.  Comstock 
once  studied  a queen  of  the  big,  black 
carpenter  ant  which  lives  under  the  bark  of 
trees.  This  queen,  without  taking  any  food 
herself,  was  able  to  lay  her  eggs  and  rear  her 
first  brood  to  maturity;  she  regurgitated 
food  for  this  first  brood,  and  then  they  went 
out  foraging  for  the  colony.  However, 
Miss  Fielde  found  that  in  the  species  she 
studied,  the  queen  could  not  do  this;  a 
question  most  interesting  to  solve  is 
whether  any  of  the  young  queens,  after  the 
marriage  flight,  are  adopted  into  other 
colonies  of  the  same  species.  As  soon  as  a 
queen  begins  laying  eggs,  she  sheds  her  then  useless  wings,  laying  them 
aside  as  a bride  does  her  veil. 

When  we  are  looking  for  ants’  nests  beneath  stones,  we  often  stumble 
upon  a colony  consisting  of  citizens  differing  in  color.  One  has  the  head 
and  thorax  rust-red  with  the  abdomen  and  legs  brown ; associated  with 
this  brown  ant,  is  a black  or  ash-colored- species.  These  black  ants  are 
the  slaves  of  the  brown  species;  but  slavery  in  the  ant  world  has  its 
ameliorations.  When  the  slave  makers  attack  the  slave  nest,  they  do  not 
fight  the  inmates  unless  they  are  obliged  to.  They  simply  loot  the  nest 
of  the  larvae  or  pupae,  which  they  carry  off  to  their  own  nests;  and  there 
they  are  fed  and  reared,  as  carefully  as  are  their  own  young.  The  slaves 
seem  to  be  perfectly  contented,  and  conduct  the  household  affairs  of  their 
masters  with  apparent  cheerfulness.  They  do  all  the  taking  care  of  the

nest  and  feeding  the  young,  but  they  are  never  permitted  to  go  out  with 
war  parties;  thus  they  never  fight,  unless  their  colony  is  attacked  by 
marauders. 

If  one  chances  upon  an  ant  battle,  one  must  needs  compare  it  to  a 
battle  of  men  before  the  invention  of  gunpowder;  for  in  those  days  fight- 
ing was  more  gory  and  dreadful  than  now,  since  man  fought  man  until 
one  of  the  twain  was  slain.  There  is  a great  variation  in  military  skill  as 
• well  as  in  courage  shown  by  different  species  of  ants ; the  species  most 
skilled  in  warfare,  march  to  battle  in  a solid  column  and  when  they  meet 
the  enemy,  the  battle  resolves  itself  into  duels,  although  there  is  no  code 
of  ant  honor  which  declares  that  one  must  fight  the  enemy  single-handed. 
Although  some  ants  are  provided  with  venomous  stings,  our  common 
species  use  their  jaws  for  weapons;  they  also  eject  upon  each  other  a very 
acid  liquid  which  we  know  as  formic  acid.  Two  enemies  approach  each 
other,  rear  on  their  hind  legs,  throw  this  ant  vitriol  at  each  other,  then 
close  in  deadly  combat,  each  trying  to  cut  the  other  in  two.  Woe  to  the 
one  on  which  the  jaws  of  her  enemy  are  once  set  ! For  the  ant  has  bull- 
dog qualities,  and  if  she  once  gets  hold,  she  never  lets  go  even  though  she 
be  rent  in  pieces  herself.  At  night  the  ant  armies  retreat  to  their  citadels, 
but  in  the  morning  fare  forth  again  to  battle ; and  thus  the  war  may  be 
waged  for  days,  and  the  battlefield  be  strewn  with  the  remains  of  the  dead 
and  dying.  So  far  as  we  are  able  to  observe,  there  are  two  chief  causes 
for  ant  wars;  one  is  when  two  colonies  desire  the  same  ground,  and  the 
other  is  for  the  purpose  of  making  slaves. 

Perhaps  the  most  interesting  as  well  as  most  easily  observed  of  all  ant 
practices,  are  those  that  have  to  do  with  plant-lice,  or  aphids.  If  we  find 
an  ant  climbing  a plant  of  any  sort,  it  is  very  likely  that  we  shall  find  she 
is  doing  it  for  the  purpose  of  tending  her  aphid  herds.  The  aphid  is  a 
stupid  little  creature  which  lives  by  thrusting  its  bill  or  sucking  tube  into 
a stem  or  leaf  of  a plant,  and  thus  settles  down  for  life,  nourished  by  the 

sap  which  it  sucks  up ; 
it  has  a peculiar  habit 
of  exuding  from  its 
alimentary  canal 
drops  of  honey-dew, 
when  it  feels  the  caress 
of  the  ant’s  antennae 
upon  its  back.  I had 
one  year  under  obser- 
vation, a nest  of  ele- 
gant little  ants  with 
shining  triangular  ab- 
domens which  they 
waved  in  the  air  like 
pennants  when  excit- 
ed. These  ants  were

and  often  one  would  seize  an  aphid  in  her  jaws  and  dash  about  madly, 
as  if  to  rescue  it  at  all  hazards.  When  the  ant  wishes  honey-dew,  she 
approaches  the  aphid,  stroking  it  or  patting  it  gently  with  her  antennas, 
and  if  a drop  of  the  sweet  fluid  is  not  at  once  forthcoming,  it  is  probably 
because  other  ants  have  previously  exhausted  its  individual  supply;  if 
the  ant  gets  no  response,  she  hurries  on  to  some  other  aphid  not  yet 
milked  dry. 

This  devotion  of  ants  to  aphids  has  been  known  for  a hundred  years, 
but  only  recently  has  it  been  discovered  to  be  of  economic  importance. 
Professor  Forbes,  in  studying  the  corn  root-louse,  discovered  that  the  ants 
care  for  the  eggs  of  this  aphid  in  their  own  nests  during  the  winter,  and 
take  the  young  aphids  out  early  in  the  spring,  placing  them  on  the  roots  of 
smartweed ; later,  after  the  corn  is  planted,  the  ants  move  their  charges 
to  the  roots  of  the  corn.  Ants  have  been  seen  to  give  battle  to  the  ene- 
mies of  the  aphid.  The  aphids  of  one  species  living  on  dogwood  are  pro- 
tected while  feeding  by  stables,  which  a certain  species  of  ant  builds  around 
them,  from  a mortar  made  of  earth  and  vegetable  matter.

LESSON  XCV 

Field  Observations  on  Ants 

Leading  thought — However  aimless  to  us  may  seem  the  course  of  the 
ant  as  we  see  her  running  about,  undoubtedly  if  we  understood  her  well 
enough,  we  should  find  that  there  is  rational  ant-sense  in  her  perform- 
ances. Therefore,  whenever  we  are  walking  and  have  time,  let  us  make 
careful  observations  as  to  the  actions  of  the  ants  which  we  may  see. 

Method — The  following  questions  should  be  written  on  the  blackboard 
and  copied  by  the  pupils  in  their  note-books.  This  should  be  done  in 
May  or  June,  and  the  answers  to  the  questions  worked  out  by  observations 
made  during  the  summer  vacation. 

Observations — i.  Where  do  you  find  ants’  nests?  Describe  all  the 
different  kinds  you  have  found.  In  what  sort  of  soil  do  they  make  their 
nests?  Describe  the  entrance  to  the  nest.  If  the  nest  is  a mound,  is 
there  more  than  one  entrance  ? Are  there  many  mounds  near  each  other? 
If  so,  do  you  think  they  all  belong  to  the  same  colony? 

2 . When  the  nest  is  disturbed,  how  do  the  ants  act  ? Do  they  usually 
try  to  save  themselves  alone?  Do  they  seek  to  save  their  young  at  the 
risk  of  their  own  lives?  If  an  ant,  carrying  a young  one  is  hard  pressed, 
will  she  drop  it  ? 

3.  Make  notes  on  the  difference  in  appearance  of  eggs,  larvae  and 
pupae  in  any  ants’  nest. 

4.  In  nests  under  stones,  can  you  find  larvae  and  pupae  assorted 
according  to  sizes? 

5 . How  many  sizes  of  ants  do  you  find  living  in  the  same  nest  ? 

6.  What  objects  do  you  find  ants  carrying  to  their  nests?  Are  these 
for  food?  How  does  an  ant  manage  to  carry  an  object  larger  than  herself? 
Do  you  ever  see  two  ants  working  together  carrying  the  same  load? 

7.  If  you  find  a procession  of  ants  carrying  food  to  their  nest,  note  if 
they  follow  the  same  path  coming  and  going.

8.  If  you  find  winged  ants  in  a nest,  catch  a few  in  a vial  with  a few 
of  the  workers,  and  compare  the  two.  The  winged  ants  are  kings  and 
queens,  the  kings  being  much  smaller  than  the  queens. 

9.  If  you  chance  to  encounter  a swarm  of  winged  ants  taking  flight, 
make  observations  as  to  the  size  of  swarm,  the  height  above  the  ground, 
and  whether  any  are  falling  to  the  earth. 

10.  Look  under  the  loose  bark  of  trees  for  nests  of  the  big,  black 
carpenter  ant.  You  may  find  in  such  situations  a queen  ant  starting  a 
colony,  which  will  prove  most  desirable  for  stocking  an  artificial  ant’s  nest. 

11.  If  you  find  ants  climbing  shrubs,  trees  or  other  plants,  look  upon 
the  leaves  for  aphids  and  note  the  following  points: 

a.  How  does  an  ant  act  as  she  approaches  an  aphid? 

b.  If  the  aphids  are  crowded  on  the  leaf,  does  she  step  on  them? 

c.  Watch  carefully  to  see  how  the  ant  touches  the  aphid  when  she 
wishes  the  honey -dew. 

d.  Watch  how  the  aphid  excretes  the  honey -dew,  and  note  if  the  ant 
eats  it. 

e.  If  you  disturb  aphids  which  have  ants  tending  them,  note  whether 
the  ants  attempt  to  defend  or  rescue  their  herds. 

f.  If  there  are  aphis-lions  or  ladybird  larvae  eating  the  aphids,  note 
if  the  ants  attack  them. 

12.  If  you  find  a colony  of  ants  under  stones  where  there  are  brown 
and  black  ants  living  together,  the  black  members  are  the  slaves  of  the 
brown.  Observe  as  carefully  as  possible  the  actions  of  both  the  black 
and  the  brown  inhabitants  of  the  nest. 

13.  If  you  chance  to  see  ants  fighting,  note  how  they  make  the 
attack.  With  what  weapons  do  they  fight?  How  do  they  try  to  get  at 
the  adversary  ? 

14.  Write  an  English  theme  covering  the  following  points:  How 

ants  take  their  slaves;  the  attitude  of  masters  and  slaves  toward  each 
other;  the  work  which  the  slaves  do,  and  the  story  of  the  ant  battle. 
How  ants  care  for  and  use  their  herds.

LESSON  XCVI 

How  to  Make  the  Lubbock  Ant-nest 

Material — Two  pieces  of  window  glass,  10  inches  square:  a sheet  of  tin, 
11  inches  square;  a piece  of  plank,  1%  inch  thick,  20  inches  long  and  at 
least  16  inches  wide;  a sheet  of  tin  or  a thin,  flat  board,  10 inches  square. 

To  make  the  nest — Take  the  plank  and  on  the  upper  side,  a short  dis- 
tance from  the  edge,  cut  a deep  furrow.  This  furrow  is  to  be  filled  with 
water,  as  a moat,  to  keep  the  ants  imprisoned.  It  is  necessary,  therefore, 
that  the  plank  should  have  no  knot  holes,  and  that  it  be  painted  thor- 
oughly to  keep  it  from  checking.  Take  the  sheet  of  tin  11  inches  square, 
and  make  it  into  a tray  by  turning  up  the  edges  three-eighths  of  an  inch. 
Place  this  tray  in  the  middle  of  the  plank.  Place  within  the  tray  one 
pane  of  glass.  Lay  around  the  edges  of  this  glass  four  strips  of  wood 
about  half  an  inch  wide  and  a little  thicker  than  the  height  of  the  ants 
which  are  to  live  in  the  nest.  Cover  the  glass  with  a thin  layer  of  fine 
earth.  Take  the  remaining  pane  of  glass  and  cut  a triangular  piece  off 


424 


Handbook  of  Nature -Study 


of  one  comer,  then  place  the  pane  on  top  of  the  other,  resting  upon  the 
pieces  of  wood  around  the  sides.  The  cover  of  the  nest  may  be  a piece  of 
tin,  with  a handle  soldered  to  the  center,  or  a board  with  a screw-eye  in  the 
center  with  which  to  lift  it.  There  should  be  a piece  of  blotter  or  of  very 
thin  sponge,  introduced  into  the  nest  between  the  two  panes  of  glass,  in  a 
position  where  it  may  be  reached  with  a pipette,  without  removing  the 
upper  glass,  for  it  must  be  kept  always  damp. 

To  establish  a colony  in  this  nest  proceed  as  follows:  Take  a two- 
quart  glass  fruit  jar  and  a garden  trowel.  Armed  with  these,  visit  some 
pasture  or  meadow  near  by,  and  find  under  some  stone,  a small  colony  of 
ants  which  have  plenty  of  eggs  and  larvae.  Scoop  up  carefully  eggs,  ants, 
dirt  and  all  and  place  in  the  jar,  being  as  careful  as  possible  not  to  injure 
the  specimens.  While  digging,  search  carefully  for  the  queen,  which  is  a 
larger  ant  and  is  sometimes  thus  found.  But  if  you  have  plenty  of  eggs, 
larvae  and  pupae,  the  ants  will  become  very  contented  in  their  new  nest 
while  taking  care  of  them.  After  you  have  taken  all  the  ants  desirable, 
place  the  cover  on  the  jar,  carry  them  to  the  Lubbock  nest  and  carefully 
empty  the  contents  of  the  fruit  jar  on  top  of  the  board  which  covers  the 
nest.  Of  course  the  furrow  around  the  plank  has  been  filled  with  water, 
so  the  stragglers  cannot  escape.  The  ants  will  soon  find  the  way  into  the 
nest  through  the  cut  comer  of  the  upper  pane  of  glass,  and  will  transfer 
their  larvae  to  it  because  it  is  dark.  After  they  are  in  the  nest,  which 
should  be  within  two  or  three  hours,  remove  the  dirt  on  the  cover,  and  the 
nest  is  ready  for  observation.  But,  since  light  disturbs  the  little  prison- 
ers, the  cover  should  be  removed  only  for  short  periods. 

The  Fielde  nest  is  better  adapted  for  a serious  study  of  ants,  but  it  is 
not  so  well  adapted  for  the  schoolroom  as  is  the  Lubbock  nest.

THE  ANT-NEST,  AND  WHAT  MAY  BE  SEEN  WITHIN  IT 
Teacher's  Story 

NT  anatomy  becomes  a very  interesting  study  when  we 
note  the  vigorous  way  the  ant  uses  it — even  to  the 
least  part.  The  slender  waist  characterizes  the  ant  as 
well  as  the  wasp;  the  three  regions  of  the  body  are 
easily  seen,  the  head  with  its  ever  moving  antennae,  the 
slender  thorax  with  its  three  pairs  of  most  efficient  legs, 
and  the  long  abdomen.  The  ant’s  legs  are  fairly  long 
as  compared  with  the  size  of  the  body  and  the  ant  can 
run  with  a rapidity  that,  comparatively,  would  soon 
outdistance  any  Marathon  runner,  however  famed.  1 
timed  an  ant  one  day  when  she  was  taking  a constitu- 
tional on  my  foot  rule.  She  was  in  no  hurry,  and  yet  she  made  time  that 
if  translated  into  human  terms  would  mean  1 6 yards  per  second.  In  addi- 
tion to  running,  many  ants  when  frightened  will  make  leaps  with  incred- 
ible swiftness. 

The  ant  does  not  show  her  cleverness  in  her  physiognomy,  probably 
because  her  eyes  seem  small  and  dull  and  she  has  a decidedly  “retreating 
forehead but  the  brain  behind  this  unpromising  appearance  is  far  more 
active  and  efficient  than  that  behind  the  gorgeous  great  eyes  of  the 
dragon-fly  or  behind  the  “high  brow”  of  the  grasshopper. 

The  ant’s  jaws  are  very  large  compared  with  her  head ; they 
work  sidewise  like  a pair  of  shears  and  are  armed  with 
triangular  teeth  along  the  biting  edges ; these  are  not  teeth 
in  a vertebrate  sense,  but  are  like  the  teeth  of  a saw.  These 
jaws  are  the  ant’s  chief  utensils  and  weapons;  with  them 
she  seizes  the  burdens  of  food  which  she  carries  home ; with 
them  she  gently  lifts  her  infant  charges;  with  them  she 
crushes  and  breaks  up  hard  food;  with  them  she  carries  out  soil  from  her 
tunnel,  and  with  them  she  fights  her  enemies.  She  also  has  a pair  of  long 
palpi,  or  feelers. 

Although  her  eyes  are  so  small  and  furnished  with  coarse  facets,  as 
compared  with  other  insects,  this  fact  need  not  count  against  her,  for  she 
has  little  need  of  eyes.  Her  home  life  is  passed  in  dark  burrows  where  her 
antenna  give  her  information  of  her  surroundings.  Note  how  these 
antennae  are  always  moving,  seeming  to  be  atremble  in  eagerness  to 
receive  sensations.  But  aside  from  their  powers  of  telling  things  by  the 
touch,  wherein  they  are  more  delicate  than  the  fingers  of  the' blind,  they 
have  other  sense  organs  which  are  comparable  to  our  sense  of  .smell. 
Miss  Fielde  has  shown  that  the  five  end  segments  of  the  antennae  have 
each  its  own  powers  in  detecting  odor.  The  end  segment  detects  the  odor 
of  the  ant’s  own  nest  and  enables  her  to.  distinguish  this  from  other  nests. 
The  next,  or  eleventh  segment,  detects  the  odor  of  any  descendant  of  the 
same  queen;  by  this,  she  recognizes  her  sisters-wherever  she  finds  them. 
Through  the  next,  or  tenth  segment,  she  recognizes  the  odor  of  her  own 
feet  on  the  trail,  and  thus  can  retrace  her  own  steps.  The  eighth  and 
ninth  segments  convey  to  her  the  intelligence  and  means  of  caring  for 
the  young.  If  an  ant  is  deprived  of  these  five  end-joints  of  the  antennae, 
she  loses  all  power  as  a social  ant  and  becomes  completely  disenfranchised. 
Miss  Fielde  gives  her  most  interesting  experiments  in  detail  in  the  Pro-

The  antenna-comb  on  the  front  leg 
of  an  ant. 


ceedings  of  the  Academy  of  Natural  Sciences  of  Philadelphia,  July  and 
October,  1901. 

It  is  natural  enough  that  the  ant,  depending  so  much  on  her  antennae 
for  impressions  and  stimuli,  should  be  very  particular  to  keep  them  clean 
and  in  good  order.  She  is  well  equipped  to  do  this,  for  she  has  a most 
efficient  antennae  brush  on  her  wrist;  it  is  practically  a circular  comb, 
which  just  fits  over  the  antenna;  and  to  see  the  ants  using  these  brushes 
is  one  of  the  most  common  sights  in  the  ant-nest  and  one  of  the  most 
amusing.  The  ant  usually  commences  by  lifting  her  leg  over  one  antenna 
and  deftly  passing  it  through  the  brush,  and  then  licks  the  brush  clean  by 

passing  it  through  her  mouth,  as  a cat 
washes  her  face;  then  she  cleans  the 
other  in  a similar  manner  and  possibly 
finishes  by  doing  both  alternately, 
winding  up  with  a flourish,  like  a 
European  gentleman  curling  his  mus- 
taches. Her  antennas  cleaned,  she 
starts  promptly  to  do  something,  for 
she  is  a little  six-footed  Martha,  al- 
ways weighed  down  or  buoyed  up  by 
many  duties  and  cares.  Keeping  her 
antennae  on  the  qui  vive,  she  assures 
herself,  by  touch,  of  the  nature  of  any 
obstacle  in  her  path.  If  she  meets 
another  ant,  their  antennae  cross  and 
pat  each  other,  and  thus  they  learn 
whether  they  are  sisters  or  aliens;  if  they  are  sisters,  they  may  stand  for 
some  time  with  their  antennae  fluttering.  One  who  has  watched  ants  care- 
fully, is  compelled  to  believe  that  they  thus  convey  intelligence  of  some 
sort,  one  to  the  other.  The  ant  is  a good  sister  “according  to  her  lights;” 
if  her  sister  is  hungry,  she  will  give  to  her,  even  from  her  own  partially 
digested  food ; the  two  will  often  stand  mouth  to  mouth  for  some  minutes 
during  this  process;  if  she  feels  inclined,  she  will  also  help  a sister  at  her 
toilet,  and  lick  her  with  her  tongue  as  one  cow  licks  another.  The  tongue 
of  the  ant  is  very  useful  in  several  ways ; with  it  she  takes  up  liquids,  and 
also  uses  it  with  much  vigor  as  a washcloth.  Sometimes  an  ant  will 
spend  a half  hour  or  more  at  her  own  toilet,  licking  every  part  of  her  own 
body  that  her  tongue  can  reach,  meanwhile  going  through  all  sorts  of 
contortions  to  accomplish  it ; she  uses  her  feet  to  scrub  portions  of  her 
body,  not  to  be  reached  by  her 
tongue. 

But  it  is  as  infant  nurse  that 
the  ant  is  a shining  example. 

No  mother  instinct  is  hers,  for 
she  has  yielded  the  power  of 
motherhood  to  the  exigencies  of 
business  life,  since  all  workers 
are  females  but  are  undeveloped 
sexually.  She  shows  far  more 
sense  in  the  care  of  her  infant 
sisters,  than  the  mother  instinct 

often  supplies  to  human  mothers.  Ants  making  their  toilets

The  ant  nurse  takes  the  eggs  as  soon  as  laid,  and  whether  or  not 
her  care  retards  or  hastens  hatching  we  know  not;  but  we  do 
know,  that  although  the  queen  ant  may  not  lay  more  than  two 
eggs  per  day,  a goodly  number  of  these  seem  to  hatch  at  the  same 
time.  The  eggs  are  massed  in  bundles  and  are  sticky  on  the  outside  so  as 
to  hold  the  bundle  together.  Miss  Fielde  says,  as  the  eggs  are  hatching, 
one  ant  will  hold  up  the  bundle,  while  another  feeds  those  which  have 
broken  the  shell.  The  larvae,  when  young,  also  hang  together  by  means 
of  tiny  hooks  on  their  bodies.  This  habit  of  the  eggs  and  young  larvae  is  a 
convenient  one,  since  an  ant  is  thus  able  to  carry  many  at  a time. 

The  larvae  are  odd  looking  little  creatures,  shaped  like  crookneck 
squashes,  the  small  end  being  the  head  and  neck  and  the  latter  being  very 
extensible.  The  ant  nurses,  by  feeding  some  more  than  others,  are  able 
to  keep  a brood  at  the  same  stage  of  development;  and  in  a well  ordered 
ant -nest,  we  find  those  of  the  same  size  in  one  nursery.  I have  often 
thought  of  a graded  school  as  I have  noted  in  ant-nests  the  youngsters 
assorted  according  to  size. 

The  ants  seem  to  realize  the  cost  and  care  of  rearing  their  young ; and 
when  a nest  is  attacked,  the  oldest,  which  are  usually  in  the  pupa  stage, 
are  saved  first.  When  the  larvae  are  young,  they  are  fed  on  regurgitated 
food;  but  as  they  grow  older,  the  food  is  brought  to  them,  or  they  to  the 
food,  and  they  do  their  own  eating.  In  one  of  my  nests,  I placed  part  of 
the  yolk  of  an  egg  hard  boiled,  and  the  ant  nurses  dumped  the  larvae  dcwn 
around  the  edges  of  it;  there  they  munched  industriously,  until  through 
their  transparent  bodies  I could  see  the  yellow  of  the  egg  the  whole  length 
of  the  alimentary  canal.  The  ant  nurses  are  very  particular  about  tem- 
peratures for  their  young,  and  Miss  Fielde  says  they  are  even  more  careful 
about  draughts.  Thus  they  are  obliged  to  move  them  about  in  the  ground 
nests,  carrying  them  down  to  the  lower  nurseries  in  the  heat  of  the  day, 
and  bringing  them  up,  nearer  to  the  warm  stones,  during  the  evenings. 
This  moving  is  always  done  carefully,  and  though  the  ant’s  jaws  are  such 
formidable  nippers,  she  carries  her  baby  sisters  with  gentleness;  and  if 
they  be  pupae,  she  holds  them  by  the  loose  pupal  skin,  like  carrying  a baby 
by  its  clothes.  The  pupae  look  like  plump  little  grain  bags,  tied  at  one 
end  with  a black  string.  They  are  the  size  of  small  grains  of  wheat,  and 
are  often  called  ants’  eggs,  which  is  absurd,  since  they  are  almost  as  large 
as  the  ant.  Ants’  eggs  are  not  larger  than  pin  points. 

The  ant  nurses  keep  the  larvae  and  pupae  very  clean  by  licking  them : 
and  when  a youngster  issues  from  the  pupa  skin,  it  is  a matter  of  much 
interest  to  the  nurses.  I have  often  seen  two  or  three  of  them  help 
straighten  out  the  cramped  legs  and  antennae  of  the  young  one,  and  hasten 
to  feed  her  with  regurgitated  food.  When  ants  first  issue  from  the  pupa 
skin  they  are  pale  in  color,  their  eyes  being  very  black  in  contrast;  they 
are  usually  helpless  and  stupid,  although  they  often  try  to  clean  their 
antennae  and  make  a toilet;  but  they  do  not  know  enough  to  follow  their 
elders  from  one  room  to  another,  and  they  are  a source  of  much  care  to  the 
nurses.  In  case  of  moving,  a nurse  will  lock  jaws  with  a “callow,”  as  a freshly 
hatched  adult  ant  is  called,  and  drag  her  along,  the  legs  of  the  callow 
sprawling  helplessly  meanwhile.  If  in  haste,  the  nurse  takes  hold  any- 
where, by  the  neck  or  the  leg,  and  hustles  her  charge  along;  if  she  takes 
her  by  the  waist  the  callow  curls  up  like  a kitten,  and  is  thus  more  easily 
moved.  After  moving  them  from  one  chamber  to  the  next,  I have  noticed 


428 


Handbook  of  Nature-Study 


that  the  callows  are  herded  together,  their  attendants  ranged  in  a circle 
about  them.  Often  we  see  one  ant  carrying  another  which  is  not  a callow, 
and  this  means  that  a certain  number  of  the  colony  h ve  made  up  their 
minds  to  move,  while  the  others  are  not  awake  to  this  necessity.  In  such 
a case,  one  of  these  energetic  sisters  will  seize  another  by  the  waist,  and 
carry  her  off  with  an  air  that  says  plainly,  “Come  along,  you  stupid!” 

Ants  are  very  cleanly  in  their  nests,  and  we  find  the  refuse  piled  in  a 
heap  at  one  corner,  or  as  far  as  possible  from  the  brood. 

If  we  are  fortunate  enough  to  find  a queen  for  the  nest,  then  we  may 
observe  the  attention  she  gets;  she  is  always  kept  in  a special  compart- 
ment, and  is  surrounded  by  ladies  in  waiting,  who  feed  her  and  lick  her 
clean  and  show  solicitude  for  her  welfare ; although  I have  never  observed 
in  an  ants’  nest,  that  devotion  to  royalty  which  we  see  in  a beehive. 

Not  the  least  interesting  scene  in  an  ants’  nest  is  when  all,  or  some,  are 
asleep  and  are  as  motionless  as  if  dead. 

LESSON  XCVII 

Observations  of  Ants  in  an  Artificial  Nest 

Leading  thought — The  ants  are  very  devoted  to  their  young  and  per- 
haps the  care  of  them  is  the  most  interesting  feature  in  the  study  of  the 
artificial  nest. 

Method — Have,  in  the  schoolroom,  a Lubbock’s  nest  with  a colony  of 
ants  within  it,  with  their  larvae  in  all  stages,  and  if  possible,  their  queen. 
For  observing  the  form  of  the  ant,  pass  one  or  two  around  in  a vial. 

Observations — i.  What  is  there  peculiar  about  the  shape  of  the  ant’s 
body  ? Can  you  see  which  section  bears  the  legs  ? Are  the  ants’  legs  long 
compared  with  her  body  ? Can  she  run  rapidly  ? 

2.  Look  at  the  ant’s  head  through  a lens,  and  describe  the  antennae, 
the  jaws  and  the  eyes. 

3.  Note  how  the  ant  keeps  her  antennae  in  motion.  Note  how  she 
gropes  with  them  as  a blind  person  with  his  hands.  Note  how  she  uses 
them  in  conversing  with  her  companions. 

4.  How  does  the  ant  clean  her  antennae?  Does  she  clean  them  more 
often  than  any  other  part  of  her  body  ? How  does  she  make  her  toilet  ? 

5 . See  how  an  ant  eats  syrup . How  do  ants  feed  each  other  ? 

6.  How  does  the  ant  carry  an  object  ? How  does  she  carry  a larva  or 
a pupa  ? Have  you  ever  seen  one  ant  carry  another  ? If  so,  describe  it. 

7.  Note  the  way  the  ants  feed  their  young.  How  do  they  keep  them 
clean  ? Does  an  ant  carry  one  egg  or  one  small  larva  at  a time  or  a bundle 
of  them  ? How  do  you  suppose  the  bundle  is  fastened  together  ? 

8.  Describe  an  egg,  a larva  and  a pupa  of  the  ant  and  tell  how  they 
differ.  Do  you  know  which  ant  is  the  mother  of  the  larvae  in  the  nest  ? 

9.  Do  you  find  larvae  of  different  sizes  all  together  in  your  nest?  Do 
you  find  larvae  and  pupae  in  the  same  group  ? Do  the  ants  move  the  young 
often  from  one  nest  to  another  ? Why  do  you  suppose  they  do  this  ? 

10.  Note  how  the  ant  nurses  take  care  of  the  callow  ant  when  it  is 
coming  out  from  the  pupa  skin.  How  do  they  assist  her  and  care  for  her? 
How  do  they  lead  her  around  ? How  do  ants  look  when  resting? 

11.  Note  where  the  ants  throw  the  refuse  from  the  nest.  Do  they 
ever  change  the  position  of  this  dump  heap  ?

THE  MUD-DAUBER 

Teacher's  Story 

THIS  little  cement  worker  is  a nervous  and  fidgety  creature, 
jerking  her  wings  constantly  as  she  walks  around  in  the 
sunshine;  but  perhaps  this  is  not  nervousness,  but 
rather  to  show  off  the  rainbow  iridescence  of  her  black 
wings;  surely  such  a slim-waisted  being  as  she,  has  a 
right  to  be  vain.  No  tight  lacing  ever  brought  about 
such  a long,  slim  waist  as  hers;  it  is  a mere  pedicel 
and  the  abdomen  is  a mere  knob  at  the  end  of  it.  The 
latter  seen  from  the  outside,  would  seem  of  little  use  as 
an  abdomen ; but  if  we  watch  the  insect  flying,  we  can 
see  plainly  that  it  is  used  to  steer  with. 

In  early  summer,  we  find  this  black  wasp  at  her  trade  as  a mason. 
She  seeks  the  edges  of  pools  or  puddles  where  she  works  industriously, 
leaving  many  little  holes  whence  she  takes  mud  to  mix  with  the  saliva, 
which  she  secretes  from  her  mouth  to  make  firm  her  cement.  This 
cement  she  plasters  on  the  under  side  of  some  roof  or  rafter  or  other  pro- 
tected place,  going  back  and  forth  until  she  has  built  a suitable  founda- 
tion. She  works  methodically,  making  a tube 
about  an  inch  long,  smooth  inside  but  rough 
outside,  the  walls  about  one-eighth  of  an  inch 
thick.  She  does  all  of  the  plastering  with  her 
jaws,  which  she  uses  as  a trowel.  When  the 
tube  is  completed  except  that  the  end  is  left 
open,  she  starts  off  in  quest  of  spiders,  and 
very  earnestly  does  she  seek  them.  I have 
seen  her  hunt  every  nook  and  comer  of  a 
piazza  for  this  prey.  When  she  finds  a spider, 
she  pounces  upon  it  and  stings  it  until  it  is 
helpless,  and  carries  it  to  her  cement  tube, 
which  is  indeed  a spider  sarcophagus,  and 
thrusts  it  within.  She  brings  more  spiders 
until  her  tube  is  nearly  full ; she  then  lays  an 
egg  within  it  and  then  makes  more  cement  and 
neatly  closes  the  door  of  the  tube.  She  then 
places  another  tube  by  the  side  of  this,  which 
she  provisions  and  closes  in  the  same  way; 
and  then  she  may  make  another  and  another 
tube,  often  a half  dozen,  under  one  adobe  roof. 

• The  wasp  in  some  mysterious  way  knows 
how  to  thrust  her  sting  into  the  spider’s  ner- 
vous system  in  a peculiar  way,  which  renders 
her  victim  unable  to  move  although  it  yet 
lives.  The  wasp  is  no  vegetarian  like  the  bee, 
and  she  must  supply  her  young  with  wasp- 
meat  instead  of  bee-bread.  Since  it  is  during  the  summer  and  hot 
weather  when  the  young  wasps  are  hatched  and  begin  their  growth,  their 
meat  must  be  kept  fresh  for  a period  of  two  or  three  weeks.  So  these 
paralyzed  spiders  do  not  die,  although  they  are  helpless.  It  is  certainly 
a practical  joke  with  justice  in  it,  that  these  ferocious  creatures  lie 


Handbook  of  Nature-Study 


helpless  while  being  eaten  by  a fat  little  grub  which  they  would  gladly 
devour,  if  they  could  move.

Drawn  by  Anna  C.  Stryke. 

The  wasp  larva  is  a whitish,  plump  grub  and  it  eats  industriously  until 
the  spider  meat  is  exhausted.  It  then  weaves  a cocoon  of  silk  about  itself 
which  just  covers  the  walls  of  its  home  tube,  like  a silken  tapestry;  within 
this  cocoon  the  grub  changes  to  a pupa.  When  it  finally  emerges,  it  is  a 
full-grown  wasp  with  jaws  which  are  able  to  cut  a door  in  the  end  of  its 
tube,  through  which  it  comes  out  into  the  world,  a free  and  accepted 
mason.  The  females  or  queens,  which  issue  late  in  the  season,  hide  in 
warm  or  protected  places  during  the  winter;  they  particularly  like  the 
folds  of  lace  window  curtains  for  hibernating  quarters.  There  they 
remain  until  spring  comes,  when  they  go  off  to  build  their  plaster  houses. 

There  are  about  seventy  species  of  mud  wasps  in  our  country.  Some 
provision  their  nests  with  caterpillars  instead  of  spiders.  This  is  true  of 
the  jug-builder,  which  makes  her  nest  jug-shaped  and  places  two  or  three 
of  them  side  by  side  upon  a twig.  She  uses  hair  in  her  mortar,  which 
makes  it  stronger.  This  is  necessary,  since  the  jug  is  saddled  upon  twigs 
and  is  more  exposed  to  the  rain  than  is  the  nest  of  the  most  common  mud- 
dauber.  The  jug-builder  is  brown  in  color  and  has  yellow  markings  on 
the  abdomen;  but  she  does  not  resemble  the  yellow-jackets,  because  she 
has  a threadlike  waist.  There  are  other  species  of  mud  wasps  which  use 
any  small  cavity  they  can  find  for  the  nest,  plastering  up  the  opening  after 
the  nest  has  been  provisioned  and  the  egg  laid.  We  often  find  keyholes, 
knot-holes  and  even  the  cavity  in  the  telephone  receiver,  plastered  up  by 
these  small  opportunists. 

The  mud-dauber  which  is  the  most  common,  and  most  likely  to  be 
selected  for  this  lesson,  is  a slender  creature  and  looks  as  if  she  were  made 
of  black  tinsel;  her  body  gives  off  glints  of  steel  and  blue;  her  abdomen 
constantly  vibrates  with  the  movement  of  breathing.  Her  eyes  are  large 
and  like  black  beads;  her  black  antennae  curve  gracefully  outward,  and 
her  wings,  corrugated  with  veins,  shimmer  with  a smoky  blue,  green  and 
purple.  She  stands  on  her  black  tip-toes  when  she  walks,  and  she  has  a 


Insect  Study 


43i 


way  of  turning  around  constantly  as  if  she  expected  an  attack  from  the 
rear.  Her  wings,  like  those  of  other  mud*  wasps  are  not  folded  fan-wise 
like  those  of  the  yellow-jacket,  but  are  folded  by  each  other  over  her  back.

LESSON  XCVIII 

The  Mud-dauber 

Leading  thought — There  are  certain  wasps  which  gather  mud  and  mix 
it  into  mortar  with  which  to  build  nests  for  their  young.  Within  these 
nests,  the  mother  wasp  places  spiders  or  insects  which  are  disabled  by  her 
sting,  for  the  food  of  the  young  wasps. 

Method — Have  the  pupils  bring  the  homes  of  the  mud  wasps  to  school 
for  observation.  The  wasps  themselves  are  very  common  in  June  and 
also  in  September,  and  they  also  may  be  studied  at  school  and  may  be 
passed  around  in  vials  for  closer  observation ; they  do  not  sting  severely 
when  handled,  the  sting  being  a mere  prick.  The  purpose  of  the  lesson 
should  be  to  stimulate  the  pupils  to  watch  the  mud-daubers  while  building 
their  nests  and  capturing  their  prey. 

Observations — 1.  Where  did  you  find  the  mud -dauber’s  nest?  How 
was  it  protected  from  the  rain?  Was  it  easily  removed?  Could  you 
remove  it  all,  or  did  some  of  it  remain  stuck  fast? 

2.  What  is  the  shape  of  the  nest?  How  does  it  look  inside?  Of  how 
many  tubes  does  it  consist?  How  long  is  each  tube?  Were  the  tubes 
laid  side  by  side? 

3.  Of  what  material  was  the  nest  made?  Is  it  not  much  harder 
than  mud?  How  did  the  wasp  change  the  mud  to  cement?  Where  did 
she  get  the  mud  ? How  did  she  carry  it  ? With  what  tools  did  she  plaster 
it? 

4.  For  what  purpose  was  the  nest  made?  Is  the  inside  of  the  tubes 
smooth  as  compared  with  the  outside  of  the  nest? 

5.  Write  a little  story  about  all  that  happens  in  one  of  these  tubes, 

including  the  following  points:  What  did  the  mother  wasp  place  in  the 

tube?  How  and  why  did  she  close  it?  What  hatched  from  the  egg  she 
placed  within  it?  How  does  the  young  wasp  look?  On  what  does  it  feed  ? 
What  sort  of  a cocoon  does  it  spin?  How  does  it  get  out  of  the  nest  when 
full-grown? 


43  2 


Handbook  of  Nature-Study 


6.  Describe  the  mud-dauber  wasp.  How  large  is  she?  What  is  the 
color  of  her  body?  Of  her  wings?  How  many  wings  has  she ? How  are 
her  wings  folded  differently  from  those  of  the  yellow-jacket?  Describe 
her  eyes;  her  antennae;  her  legs; ' her  waist;  her  abdomen. 

7.  Where  did  you  find  the  wasp?  How  did  she  act?  Do  you  think 
that  she  can  sting?  How  does  she  pass  the  winter? 

8.  Do  you  knew  the  mud  wasps  which  build  the  little,  jug-shaped 
nests  for  their  young?  Do  you  know  the  mud  wasps  which  utilize 
crevices  and  keyholes  for  their  nests  and  plaster  up  the  opening? 

9.  Do  you  know  about  the  digger  wasps  which  pack  away  grasshop- 
pers or  caterpillars  in  a hole  in  the  ground,  in  which  they  lay  their  egg  and 
then  cover  it?

THE  YELLOW-JACKET 

Teacher's  Story 

ANY  wasps  are  not  so  waspish  after  all  when  we  under- 
stand one  important  fact  about  them;  i.  e., 
although  they  are  very  nervous  themselves,  they 
detest  that  quality  in  others.  For  years  the 
yellow- jackets  have  shared  with  us  our  meals  at 
our  summer  camp  on  the  lake  shore.  They  make 
inquisitive  tours  of  inspection  over  the  viands  on 
the  table,  often  seeming  to  include  ourselves,  and 
coming  so  near  that  they  fan  our  faces  with  their 
wings.  They  usually  end  by  selecting  the 
sweetened  fruits,  but  they  also  carry  off  bits  of 
roast  beef,  pouncing  down  upon  the  meat  platter 
and  seizing  a tidbit  as  a hawk  does  a chicken . We  always  remain  calm 
during  these  visitations,  for  we  know  that  unless  we  inadvertently  pinch 
one,  we  shall  not  be  harmed;  and  it  is  great  fun  to  watch  one  of  these 
graceful  creatures  poising  daintily  on  the  side  of  the  dish  lapping  up  the 
fruit  juice  as  a cat  does  milk,  the  slender,  yellow-banded  abdomen  pal- 
pitating as  she  breathes.  Occasionally,  two  desire  the  same  place,  and  a 
wrestling  match  ensues  which  is  fierce  while  it  lasts,  but  the  participants 
always  come  back  to  the  dish  unharmed.  They  are  extra  polite  in  their 
manners,  for  after  one  has  delved  eagerly  into  the  fruit 
syrup,,  she  proceeds  to  clean  her  front  feet  by  passing 
them  through  her  jaws,  which  is  a wasp  way  of  using  a 
finger  bowl. 

Both  yellow-jackets  and  the  white-faced  black- 
hornets  build  in  trees  and  similarly,  although  the  paper 
made  by  the  yellow-jackets  is  finer  in  texture.  However, 
some  species  of  yellow-jackets  build  their  nests  in  the 
ground,  but  of  similar  form.  The  nest  is  of  paper  made  Ayellow- 
of  bits  of  wood  which  the  wasps  pull  off  with  their  jaws  ]ac  et 
from  weather-worn  fences  or  boards.  This  wood  is  reduced  to  a pulp  by 
saliva  which  is  secreted  from  the  wasp’s  mouth,  and  is  laid  on  in  little 


Insect  Study 


433 


layers  which  can  be  easily  seen  by  examining  the  outside  of  the  nest. 
These  layers  may  be  of  different  colors.  A wasp  Mull  come  with  her  load 
of  paper  pulp,  and  using  her  jaws  and  front  feet  for  tools  she  will  join  a 
strip  to  the  edge  of  the  paper  and  pat  it  into  shape.  The  paper  tears  more 
readily  along  the  lines  of  the  joining,  than  across.  The  cover  of  the  nest 
is  made  of  many  layers  of  shell-like  pieces  fastened  together  and  the  outer 
layers  are  waterproof;  the  opening  of  a nest  is  at  the  bottom.  Mr.  Lub- 
bock has  shown  that  certain  wTasps  are  stationed  at  the  door,  as  sentinels, 
to  give  warning  on  the  approach  of  the  enemy.  The  number  of  stories  of 
combs  in  a nest  depends  upon  the  age  and  size  of  the  colony.  They  are 
fastened  together  firmly  near  the  center,  by  a central  core  or  axis  of  very 
strong,  firm  paper,  which  at  the  top  is  attached  to  a branch  or  whatever 
supports  the  nest.  The  cells  all  open  downward,  in  this  respect  differing 
from  those  of  the  honey-bee,  which  are  usually  placed  horizontal.  The 
wasp-comb  differs  from  the  honey-comb  in  that  it  is  made  of  paper  instead 
of  wax,  and  that  the  rows  of  cells  are  single  instead  of  double.  The  cells 
in  the  wasp-comb  are  not  for  storing  honey,  but  are  simply  the  cradles  for 
the  young  wasps.  (See  Fig.  p,  457.) 

Sometimes  a wasp  family  disaster  makes  it  possible  for  us  to  examine 
one  of  these  nests  with  its  inmates.  Here  we  find  in  some  of  the  cells,  the 
long  white  eggs  fastened  to  the  very  bottom  of  the  cell,  in  an  inner  angle, 
as  if  a larva  when  hatched  needed  to  have  a cozy  corner.  These  wasp 
larvae  are  the  chubbiest  little  grubs  imaginable  and  are  very  soft  bodied. 
It  was  once  a mystery  to  me  how  they  were  able  to  hang  in  the  cells,  head 
down,  without  getting  “black  in  the  face”  or  falling  out;  but  this  was 
made  plain  by  studying  the  little  disk  at  the  rear  end  of  the  larva’s  body, 
which  is  decidedly  sticky;  after  a larva  is  dead,  its  heavy  body  can  be 
lifted  by  pressing  a match  against  this  disk;  thus  it  evidently  suffices  to 
keep  the  baby  wasp  stuck  fast  to  its  cradle.  The  larva’s  body  is  mostly 
covered  with  a white,  papery,  soft  skeleton  skin ; the  head  is  yellowish  and 
highly  polished,  looking  like  a drop  of  honey.  At  one  side  may  be  seen  a 
pair  of  toothed  jaws,  showdng  that  it  is  able  to  take  and  chew  any  food 
brought  by  the  nurses.  They  seem  to  be  well  trained  youngsters  for  they 
all  face  toward  the  center  of  the  nest,  so  that  a nurse,  when  feeding  them, 
can  move  from  one  to  another  without  having  to  pass  to  the  other  .side  of 
the  cell.  It  is  a funny  sight  to  behold  a combful  of  well  grown  larvae,  each 
fitting  in  its  cell  like  meal  in  a bag  and  with  head  and  several  segments 
projecting  out  as  if  the  bag  were  overflowing.  It  behooves  the  wasp 
larva  to  get  its  head  as  far  out  of  the  cell  as  possible,  so  that  it  will  not  be 
overlooked  by  the  nurses;  the  little  ones  do  this  by  holding  themselves  at 
the  angle  of  the  cell ; this  they  accomplish  by  wedging  the  back  into  the 
corner.  These  young  larvae  do  not  face  hrwards  like  the  older  ones,  but 
iiey  rest  in  an  inner  angle  of  the  cell. 

After  a larva  has  reached  the  limit  of  its  cell  room,  it  spins  a veil 
around  itself  and  fastens  it  at  the  sides,  so  that  it  forms  a lining  to  the 
upper  part  of  the  cell  and  makes  a bag  over  the  “head  and  shoulders”  of 
the  insect.  This  cocoon  is  very  tough,  and  beneath  its  loose  dome  the 
larva  skin  is  shed ; the  pupa  takes  on  a decidedly  waspish  form,  except 
that  the  color  is  all  black;  the  legs  and  the  wings  are  folded  piously  down 
the  breast  and  the  antennae  lie  meekly  each  side  of  the  face,  wdth  the 
“hands”  folded  outside  of  them;  the  strong  toothed  jaws  are  ready,  so 
that  when  the  pupa  skin  is  molted,  the  insect  can  cut  its  silken  curtain, 
and  come  out  into  its  little  nest  world,  as  a Ml-fledged  vellow-jacket.

What  a harlequin  the  wasp  is,  in  her  costume  of  yellow  and  black! 
Often  in  the  invertebrate  world  these  colors  mean  “sit  up  and  take 
notice,”  and  the  wasp’s  costume  is  no  exception. 
Whoever  has  had  any  experience  in  meddling  with 
yellow-jackets,  avoids  acquaintance  with  all  yellow 
and  black  insects.  Yet  we  must  confess  that  the  lady 
wasp  has  good  taste  in  dress.  The  yellow  cross  bands 
on  her  black  skirt  are  scalloped,  and,  in  fact,  all  her 
yellow  is  put  on  in  a most  chic  manner;  she,  being 

Looking  a wasp  slender,  can  well  afford  to  dress  in  roundwise  stripes, 
in  the  face.  and  she  folds  her  wings  prettily  like  a fan,  and  not  over 
her  back  like  the  mud  wasp,  which  would  cover  her  decorations.  There 
is  a sensation  coming  to  the  one  who,  armed  with  a lens,  looks  a wasp  in  the 
face ; she  always  does  her  hair  pompadour,  and  the  yellow  is  here  put  on 
with  a most  bizarre  effect,  in  points  and  arabesques.  Even  her  jaws  are 
yellow  with  black  borders  and  black  notches.  Her  antennae  are  velvety 
black,  her  legs  are  yellow,  and  her  antennae  comb,  on  her  wrist,  is  a real 
comb  and  quite  ornate. 

In  the  nest  which  we  studied  in  late  August,  the 
queen  cells  were  just  being  developed.  They  were  placed 
in  a story  all  by  themselves,  and  they  were  a third  larger 
than  the  cells  of  the  workers.  The  queen  of  this  nest  was 
a most  majestic  wasp,  fully  twice  as  large  as  any  of  her 
subjects;  her  face  was  entirely  black,  and  the  yellow 
bands  on  her  long  abdomen  were  of  quite  a different  pat- 
tern than  those  on  the  workers ; her  sting  was  not  so  long 
in  proportion,  but  I must  confess  it  looked  efficient.  In  cofnb  wrist 
fact,  a yellow-jacket’s  sting  is  a formidable  looking  spear  my  a y as & 
when  seen  through  a microscope,  since  it  has  on  one  side  some  backward 
projecting  barbs,  meant  to  hold  it  firm  when  driving  home  the  thrust. 

While  wasps  are  fond  of  honey  and  other  sweets,  they  are  also  fond  of 
animal  food  and  eat  a great  many  insects,  benefiting  us  greatly  by 
destroying  mosquitoes  and  flies.  As  no  food  is  stored  for  their  winter  use, 
all  wasps  excepting  the  queens  die  of  the  cold.  The  queens  crawl  away 
to  protected  places  and  seem  to  be  able  to  withstand  the  rigors  of  winter; 
each  queen,  in  the  spring,  makes  a little  comb  of  a few  cells,  covering  it 
with  a thin  layer  of  paper.  She  then  lays  eggs  in  these  cells  and  gathers 
food  for  the  young;  but  when  these  first  members  of  the  family,  which  are 
always  workers,  come  to  maturity,  they  take  upon  themselves  the  work 
of  enlarging  the  nest  and  caring  for  the  young.  After  that,  the  queen 
devotes  her  energies  to  laying  eggs. 

Wasps  enlarge  their  houses  by  cutting  away  the  paper  from  the  inside 
of  the  covering,  to  give  more  room  for  building  the  combs  wider;  to  com- 
pensate for  this,  they  build  additional  layers  on  the  outside  of  the  nest. 
Thus  it  is,  that  every  wasp’s  nest,  however  large,  began  as  a little  comb  of 
a few  cells  and  was  enlarged  to  meet  the  needs  of  the  rapidly  growing 
family.  Ordinarily  the  nest  made  one  year  is  not  used  again.

LESSON  XCIX 
The  Yellow-jacket 

Leading  thought — The  wasps  were  the  original  paper  makers,  using 
wood  pulp  for  the  purpose.  Some  species  construct  their  houses  of  paper 
in  the  trees  or  bushes  while  others  build  in  the  ground. 

Method — Take  a deserted  wasp-nest,  the  larger  the  better,  with  sharp 
scissors  remove  one  side  of  the  covering  of  the  nest,  leaving  the  combs 
exposed  and  follow  with  the  questions  and  suggestions  indicated.  From 
this  study  of  the  nest  encourage  the  children  to  observe  more  closely  the 
wasps  and  their  habits,  which  they  can  do  in  safety  if  they  learn  to  move 
quietly  while  observing.  (See  Fig.  page  457.) 

Observations — 1.  Which  kind  of  wasp  do  you  think  made  this  nest? 
Of  what  is  the  nest  made?  Where  did  the  wasp  get  the  material?  How 
do  the  wasps  make  wood  into  paper  ? 

2.  What  is  the  general  shape  of  the  nest  ? Is  the  nest  well  covered  to 
protect  it  from  rain?  Where  is  the  door  where  the  wasps  went  in  and 
out?  Is  the  covering  of  the  nest  all  of  the  same  color?  Do  these  differ- 
ences in  color  give  you  any  idea  of  how  the  wasps  build  the  paper  into  the 
nest?  Does  the  paper  tear  more  easily  one  way  than  another?  Is  the 
covering  of  the  nest  solid  or  in  layers? 

3 . How  many  combs  or  stories  are  there  in  the  wasp  house  ? How 
are  they  fastened  together  and  how  suspended  ? 

4.  Compare  the  combs  of  the  wasp-nest  with  those  of  the  honey-bee. 
How  do  they  resemble  each  other  and  how  differ?  Do  the  cells  open  up- 
ward or  downward?  For  what  purpose  are  the  combs  in  the  wasp-nest 
used?  Are  all  the  cells  of  the  same  size?  Do  you  know  the  reason  for 
this  difference  in  size  ? 

5.  How  do  the  young  wasp  grubs  manage  to  cling  to  the  cells  head 
downward  ? Are  the  cells  lined  with  a different  color  and  does  this  lining 
extend  out  over  the  opening  in  some  cases?  Is  this  lining  of  the  cells 
made  of  paper  also  ? Do  you  know  how  a young  wasp  looks  and  how  the 
white  lining  of  the  cells  is  made? 

6.  Do  you  believe  that  some  wasps  of  the  colony  are  always  posted  as 
sentinels  at  the  door  to  give  warning  if  the  colony  is  attacked  ? 

7.  Do  wasps  store  food  to  sustain  them  during  the  winter?  What 
happens  to  them  during  winter?  Is  the  same  nest  used  year  after  year. 

8.  Can  you  describe  the  beginning  of  this  wasp-nest?  When  was  it 
made?  Tell  the  story  of  the  wasp  that  made  it.  How  large  was  the  nest 
at  first  ? How  was  the  nest  enlarged  ? 

9.  What  is  the  food  of  wasps?  How  do  these  insects  benefit  us? 

10.  Write  a story  giving  the  life  history  of  a wasp. 

11.  In  the  summer  watch  a yellow-jacket  eat  from  a dish  of  sweetened 
fruit  which  you  may  place  out  of  doors  to  coax  her  to  come  where  you  can 
carefully  observe  her.  What  are  the  colors  of  the  yellow- jacket?  Where 
is  the  yellow?  How  are  the  yellow  bands  made  ornamental?  How  does 
she  fold  her  wings  ? How  many  wings  has  she  ? What  is  the  color  of  her 
legs?  Describe  her  antennae  and  eyes.  How  does  she  eat  the  fruit  juice? 
Can  you  see  the  motion  of  her  body  when  she  breathes?

THE  LEAF-CUTTER  BEE 
Teacher's  Story 

fE  beautiful  day  in  late  June  when  I was  picking  some 
roses,  I saw  a bee,  almost  as  large  as  a honey-bee  but 
different  in  shape  and  darker  in  color,  alight  on  a leaf 
and  moving  with  nervous  rapidity,  cut  a circle  out  of 
a leaf  with  her  jaws  “quicker’n  a wink;”  then  taking 
the  piece  between  her  fore-feet  and  perhaps  holding  it 
also  with  her  jaws,  she  flew  away,  the  green  disk 
looking  as  large  in  proportion  to  her  size  as  a big  base 
drum  hung  to  the  neck  of  a small  drummer.  I waited 
long  for  her  to  come  back,  but  she  came  not ; mean- 
while I examined  the  leaves  of  the  rose  bush  and 
found  many  circlets,  and  also  many  oblong  holes  with  the  ends  deeply 
rounded,  cut  from  the  leaflets. 

I knew  the  story  of  the  little  bee  and  was  glad  I had  seen  her  cut  a 
leaflet  with  her  jaw  shears,  which  work  sidewise  like  real  shears.  I knew 
that  somewhere  she  had  found  a cavity  big  enough  for  her  needs ; perhaps 
she  had  tunneled  it  herself  in  the  dead  wood  of  some  post  or  stump,  using 
her  jaws  to  cut  away  the  chips;  maybe  she  had  found  a crevice  beneath 
the  shingles  of  a roof  or  beneath  a stone  in  the  field,  or  she  may  have  rolled 
a leaf;  anyway,  her  little  cave  was  several  inches  long,  circular  in  outline 
and  large  enough  io  admit  her  body.  She  first  cut  a long  piece  from  the 
rose  leaf  and  folded  it  at  the  end  of  the  tunnel;  and  then  she  brought 
another  and  another  long  piece  and  bent  and  shaped  them  into  a little 
thimble-like  cup,  fastening  them  together  with  some  saliva  glue,  from  her 
mouth.  After  the  cup  was  made  to  her  liking,-  she  went  in  search  of  food, 
which  was  found  in  the  pollen  of  some  flowers.  This  pollen  was  carried 
not  as  the  honey-bees  do,  because  she  has  no  pollen  baskets  on  her  legs; 
but  it  was  dusted  into  the  fur  on  the  lower  side  of  her  body;  as  she 
scraped  the  pollen  off,  she  mixed  it  with  some  nectar  which  she  had 
also  found  in  the  flowers,  and  made  it  into  a pasty  mass  and  heaped  it  at 
the  bottom  of  the  cup;  she  probably  made  many  visits  to  flowers  before 
she  had  a sufficient  amount  of  this  bee  pastry,  and  then  she  laid  an  egg 
upon  it ; after  this,  she  immediately  flew  back  to  the  rose  bush  to  cut  a lid 
for  her  cup.  She  is  a nice  mathematician  and  she  cuts  the  lid  just  a little 
larger  than  the  rim  of  the  cup,  so  that  it  may  be  pushed  down  in,  making 
it  fit  very  closely  around  the  edges;  she  then  cuts  another  and  perhaps 
another  of  the  same  size  and  puts  them  over  and  fastened  to  the  first  cover. 
When  finished,  it  is  surely  the  prettiest  baby  basket  ever  made  by  a 
mother,  all  safely  enclosed  to  keep  out  enemies.  But  her  work  is  then 
only  begun.  She  has  other  baby  baskets  to  make  and  she  perhaps  makes 
ten  or  more,  placing  one  cup  just  ahead  of  another  in  the  little  tunnel. 

But  what  is  happening  meanwhile  to  the  bee  babies  in  the  baskets? 
The  egg  hatches  into  a little  white  bee  grub  which  falls  to  and  eats  the 
pollen  and  nectar  paste  with  great  eagerness.  As  it  eats,  it  grows  and 
sheds  its  skeleton  skin  as  often  as  it  becomes  too  tight,  and  then  eats  and 
grows  some  more.  How  many  mothers  would  know  Just  how  much  food 
it  would  require  to  develop  a child  from  infancy  until  it  grows  up ! This 
bee  mother  knows  well  this  amount  and  when  the  food  is  all  gone,  the  little 
bee  grub  is  old  enough  to  change  to  a pupa;  it  looks  very  different  now,

and  although  mummy-shaped  we  can  see  its  folded  wings  and  antennae. 
After  remaining  a motionless  pupa  for  a few  days,  it  sheds  its  pupa  skin 
and  now  it  is  a bee  just  like  its  mother;  but  as  the  oldest  bee  is  at  the 
bottom  of  the  tunnel,  even  after  it  gets  its  wings  and  gnaws  its  way  out  of 
its  basket,  it  very  likely  cannot  escape  and  find  its  way  out  into  the  sun- 
shiny world,  until  its  younger  brothers  and  sisters  have  gone  out  before  it. 

There  are  many  species  of  these  leaf-cutter  bees  and  each  species  makes 
its  own  kind  of  a nest,  always  cutting  the  same  size  of  circlets  and  usually 
choosing  its  own  special  kind  of  leaf  to  make  this  cradle.  Some  are 
daintier  in  their  tastes  and  use  rolled  petals  instead  of  leaves;  and  we 
have  found  some  tiny  cups  made  of  gorgeous  peony  petals,  and  some  of 
pansy  petals,  a most  exquisite  material. 

At  Chautauqua  we  found  a species  which  rolled  maple  leaves  into  a 
tube  which  held  three  or  four  cups,  and  we  also  found  there  a bee  stowing 
her  cups  in  the  open  end  of  a tubular  rod,  used  to  hold  up  an  awning. 
There  are  other  species  which  make  short  tunnels  in  the  ground  for  their 
nests,  but  perhaps  the  most  common  of  all  wedge  their  cups  between  or 
beneath  the  shingles  on  the  roofs  of  summer  cottages.  But,  however  or 
wherever  the  leaf-cutter  works,  she  is  a master  mechanic  and  does  her 
work  with  niceness  and  daintiness.

LESSON  C 

The  Leaf-cutter  Bee 

Leading  thought — When  we  see  the  edges  of  rose  leaves  with  holes  of 
regular  pattern  in  them,  some  of  the  holes  being  oblong  and  some  circular, 
we  know  the  leaf-cutter  bee  has  cut  them  to  make  her  cradle  cups. 

Method — It  is  very  easy  to  find  in  June  or  autumn  the  leaves  from 
which  the  leaf-cutter  bee  has  cut  the  bedding  for  her  young.  Encourage 
the  pupils  to  look  for  the  nest  during  the  summer  and  to  bring  some  of  the 
cups  to  school  when  they  return,  where  they  may  be  studied  in  detail; 
meanwhile  the  teacher  may  tell  the  story  of  the  nest.  This  is  rather 
difficult  for  the  pupils  to  work  out. 

Observations — i . Do  you  find  rose  leaves  with  round  holes  cut  in  their 
edges?  Do  you  find  on  the  same  bush  some  leaflets  with  oblong  holes  in 
them?  Sketch  or  describe  the  rose  leaf  thus  cut,  noting  exactly  the  shape 
of  the  holes.  Are  the  circular  holes  of  the  same  size?  Are  the  long  holes 
about  equal  in  size  and  shape?  Do  you  find  any  other  plants  with  holes 
like  these  cut  in  them?  Do  you  find  any  petals  of  flowers  thus  cut? 

2.  What  do  you  think  made  these  holes?  If  an  insect  was  taking  a 
leaf  for  food  would  the  holes  be  as  regular?  Watch  the  rose  bush  care- 
fully and  see  if  you  can  discover  the  insect  which  cuts  the  leaf.

3.  Have  you  ever  seen  the  little  black  bee  carrying  pieces  of  rose 
leaves  between  her  front  feet?  With  what  instrument  do  you  suppose  she 
cut  the  leaves?  Where  do  you  think  she  was  going? 

4.  Have  you  ever  found  the  nest  of  the  leaf-cutter  bee?  Was  it  in  a 
tunnel  made  in  dead  wood  or  in  some  crack  or  cranny?  How  many  of  the 
little  rose  leaf  cups  are  there  in  it?  How  are  the  cups  placed?  Are  the 
little  bees  still  in  the  cups  or  can  you  see  the  holes  through  which  they 
crawled  out? 

5.  Take  one  cup  and  study  it  carefully.  How  are  the  pieces  of 
leaves  folded  to  make  the  cups  ? How  is  the  lid  put  on  ? Soak  the  cup  in 
water  until  it  comes  apart  easily.  Describe  how  many  of  the  long  pieces 
were  used  and  how  they  were  bent  to  make  a cup.  Of  how  many  thick- 
nesses is  the  cover  made?  Are  the  covers  just  the  same  size  or  a little 
larger  than  the  top  of  the  cup?  How  does  the  cover  fit  so  tightly? 

6.  If  you  find  the  nest  in  July  or  early  August,  examine  one  of  the 
cups  carefully  and  see  what  there  is  in  it.  Take  off  the  cover  without 
injuring  it.  What  is  at  the  bottom  of  the  nest?  Is  there  an  insect 
within  it?  How  does  it  look?  What  is  it  doing?  Of  what  do  you  think 
its  food  was  made?  How  and  by  whom  was  the  food  placed  in  the  cup? 
Place  the  nest  in  a box  or  jar  with  mosquito  netting  over  the  top,  and  put 
it  out  of  doors  in  a safe  and  shaded  place.  Look  at  it  often  and  see  what 
this  insect  changes  into. 

7.  If  the  mother  bee  made  each  little  nest  cup  and  put  in  the  bee- 
bread,  and  honey  for  her  young,  which  cup  contains  the  oldest  of  the 
family?  Which  the  youngest?  How  do  you  think  the  full-grown  bees 
get  out  of  the  cup  ? 

8.  Do  you  think  that  the  same  species  of  bee  always  cuts  the  same 
sized  holes  in  a leaf?  Is  it  the  same  species  which  cuts  the  rose  leaves  and 
the  pansy  petals? 


THE  LITTLE  CARPENTER-BEE 
Teacher's  Story 

AKE  a dozen  dead  twigs  from  almost  any  sumac  or 
elder,  split  them  lengthwise,  and  you  will  find  in  at 
least  one  or  two  of  them,  a little  tunnel  down  the  cen- 
ter where  the  pith  once  was.  In  the  month  of  June 
or  July,  this  narrow  tunnel  is  made  into  an  insect 
apartment  house,  one  little  creature  in  each  apart- 
ment, partitioned  off  from  the  one  above  and  the  one 
below.  The  nature  of  this  partition  reveals  to  us 
whether  the  occupants  are  bees  or  wasps;  if  it  is 
made  of  tiny  chips,  like  fine  sawdust  glued  together,  a 
bee  made  it  and  there  are  little  bees  in  the  cells ; if  it 
is  made  of  bits  of  sand  or  mud  glued  together,  a wasp  was  the  architect 
and  young  wasps  are  the  inhabitants.  Also,  if  the  food  in  the  cells  is 
pollen  paste,  it  was  placed  there  by  a bee;  if  of  paralyzed  insects  or 
spiders,  a wasp  made  the  nest. 

The  little  carpenter-bee  ( Ceratina  dupla)  is  a beautiful  creature, 
scarcely  one  quarter  of  an  inch  in  length,  with  metallic  blue  body  and

rainbow  tinted  wings.  In  May,  she  selects  some  broken  twig 
of  sumac,  elder  or  raspberry,  which  gives  her  access  to  the 
pith;  this  she  at  once  begins  to  dig  out,  mouthful  by  mouth- 
ful, until  she  has  made  a smooth  tunnel  several  inches  long; 
she  then  gathers  pollen  and  packs  bee-bread  in  the  bottom  of 
the  cell  to  the  depth  of  a quarter-inch,  and  then  lays  upon 
it,  a tiny  white  egg.  She  then  brings  back  some  of  her  chips 
of  pith  and  glues  them  together,  making  a partition  about  one- 
tenth  of  an  inch  thick,  which  she  fastens  firmly  to  the  sides  of 
the  tunnel ; this  is  the  roof  for  the  first  cell  and  the  floor  of 
the  next  one ; she  then  gathers  more  pollen,  lays  another  egg, 
and  builds  another  partition. 

Thus  she  fills  the  tunnel,  almost  to  the  opening,  with  cells, 
sometimes  as  many  as  fourteen ; but  she  always  leaves  a space 
for  a vestibule  near  the  door,  and  in  this  she  makes  her  home 
while  her  family  below  her  are  growing  up. 

The  egg  in  the  lowest  cell  of  course  hatches  first;  a little 
bee  grub  issues  from  it  and  eats  the- bee-bread  industriously 
and  grows  by  shedding  his  skin  when  it  becomes  too  tight; 
then  he  changes  to  a pupa  and  later  to  a bee  resembling  his

or  less  busy  pushing  behind  him  the  broken  bits  of  all  the 
partitions  above  him.  Finally,  the  youngest  gets  his  growth,  and  th^re 
they  all  are  in  the  tunnel,  the  broken  partitions  behind  the  hindmost  at 
the  bottom  of  the  nest,  and  the  young  bees  packed  closely  together  in  a 
row  with  heads  toward  the  door.  When  we  find  the  nest  at  this  period, 
we  know  the  mother  because  her  head  is  toward  her  young  ones  and  her 
back  to  the  door.  A little  later,  on  some  bright  morning,  they  all  come 
out  into  the  sunshine  and  flit  about  on  gauzy,  rainbow  wings,  a very 
happy  family,  out  of  prison. 

But  if  the  brood  is  a late  one,  the  home  must  be  cleaned  out  and  used  as 
a winter  nest,  and  still  the  loyal  little  mother  bee  stays  true  to  her  post ; 
she  is  the  last  one  to  enter  the  nest;  and  not  until  they  are  all  housed 
within,  does  she  enter.  It  is  easy  to  distinguish  her  for  her  poor  wings  are 
torn  and  frayed  with  her  long  labor  of  building  the  nest,  until  they  scarcely 
serve  to  carry  her  afield ; but  despite  this  she  remains  on  guard  over  her 
brood,  for  which  she  has  worn  out  her  own  life.

The  story  of  the  little  carpenter-wasps  Is  similar  to  that  of  the  bee, 
except  that  we  have  reason  to  believe  they  often  use  her  abandoned 
tunnels  instead  of  making  new  ones  They  make  their  little  partitions 
out  of  mud ; their  pupse  are  always  in  long,  slender,  silken  cocoons,  and  we 
have  no  evidence  that  the  mother  remains  in  attendance. 


LESSON  Cl 

The  Little  Carpenter-bee 

Leading  thought — Not  all  bees  live  in  colonies  like 
the  honey-bees  and  bumblebees.  One  tiny  bee  rears 
her  brood  within  a tunnel  which  she  makes  in  the 
pith  of  sumac,  elder  or  raspberry. 

Method — This  lesson  may  be  given  in  June  or  in 
October.  In  June,  the  whole  family  of  bees  in  their 
apartments  may  be  observed;  in  autumn,  the  empty 
tenement  with  the  fragments  of  the  partitions  still 
clinging  may  be  readily  found  and  examined;  and 
sometimes  a whole  family  may  be  found,  stowed  away 
in  the  home  tunnel,  for  the  winter. 

Observations — 1.  Collect  dead  twigs  of  sumac  or 
elder  and  cut  them  in  half,  lengthwise.  Do  you  find 
any  with  the  pith  tunneled  out? 

2 How  long  is  the  tunnel  ? Are  its  sides  smooth  ? 
Can  you  see  the  partitions  which  divide  the  long 
narrow  tunnel  into  cells  ? Look  at  the  partitions  with 
a lens,  if  necessary,  to  determine  whether  they  are  made 
of  tiny  bits  of  wood  or  of  mud.  If  made  of  mud,  what 
insect  made  them  ? If  of  little  chips  how  and  by  what 
were  they  constructed  ? 

3.  Are  there  any  insects  in  the  cells?  If  so, 
describe  them.  Is  there  bee-bread  in  the  cells? 

4.  For  what  was  the  tunnel  made?  With  what 
tools  was  it  made?  How  are  the  partitions  fastened 
together?  How  does  a young  bee  look? 

5.  Write  the  story  of  the  oldest  of  the  bee  family 
which  lived  in  this  tunnel.  Why  did  it  hatch  first? 
On  what  did  it  feed?  When  it  became  a full  fledged 
bee,  what  did  it  do?  How  did  it  finally  get  out? 

6 Take  a glass  tube,  the  hollow  at  the  center 
being  about  one-eighth  of  an  inch  across,  a tube 
which  you  can  get  in  any  drug-store.  Break  this 
tube  into  sections,  six  or  seven  inches  long,  wrap 
around  each  a black  paper  or  cloth,  made  fast  with 
rubber  bands  and  suspend  them  in  a hedge  or  among 
thick  bushes  in  May.  Examine  these  tubes  each  week 
to  see  if  the  wasps  or  bees  are  using  them.

THE  BUMBLEBEE 
Teacher's  Story 

Thou,  in  sunny  solitudes, 

Rover  of  the  underwoods, 

The  green  silence  dost  replace 
With  thy  mellow,  breezy  bass. 

— Emerson. 

HERE  seems  to  have  been  an  hereditary  war  between 
the  farm  boy  and  the  bumblebee,  the  hostilities 
usually  initiated  by  the  boy.  Like  many  wars,  it 
is  very  foolish  and  wicked,  and  has  resulted  in  great 
harm  to  both  parties.  Luckily,  the  boys  of  to-day  are 
more  enlightened;  and  it  is  to  be  hoped  that  they 
will  learn  to  endure  a bee  sting  or  two  for  the  sake  of 
protecting  these  diminishing  hosts,  upon  which  so 
many  flowers  depend  for  carrying  their  pollen ; for 
of  all  the  insects  of  the  field,  the  bumblebees  are  the  best  and  most 
needed  friends  of  the  flowers. 

The  bumblebees  are  not  so  thrifty  and  forehanded  as  are  the  honey- 
bees, and  do  not  provide  enough  honey  to  sustain  the  whole  colony  during 
the  winter.  Only  the  mother  bees,  or  queens  as  they  are  called,  survive 
the  cold  season.  Just  how  they  do  it,  we  do  not  know,  but  probably  they 
are  better  nourished  and  therefore  have  more  endurance  than  the  workers. 
In  early  May,  one  of  the  most  delightful  of  spring  visitants  is  one  of  these 
great  buzzing  queens,  flying  low  over  the  freshening  meadows,  trying  to 
find  a suitable  place  for  her  nest;  and  the  farmer  or  fruit  grower  who 
knows  his  business,  is  as  anxious  as  she  that  she  find  suitable  quarters, 
knowing  well  that  she  and  her  children  will  render  him  most  efficient  aid 
in  growing  his  fruit  and  seed.  She  finally  selects  some  cosy  place,  very 
likely  a deserted  nest  of  the  field  mouse,  and  there  begins  to  build  her 
home.  She  toils  early  and  late,  gathering  pollen  and  nectar  from  the 
blossoms  of  the  orchard  and  other  flowers  which  she  mixes  into  a loaf  as 
large  as  a bean  upon  which  she  lays  a few  tiny  eggs  and  then  covers  with 
wax.  She  then  makes  a honey-pot  of  wax  as  large  as  a small  thimble  and 
fills  it  with  honey;  thus  provided  with  food  she  broods  over  her  eggs, 
keeping  them  warm  until  they  hatch.  Each  little  bee  grub  then  burrows 
into  the  bee-bread  making  for  itself  a cave  while  satisfying  its  hunger. 
When  fully  grown,  it  spins  about  itself  a cocoon,  changes  to  a pupa  and 
then  comes  out  a true  bumblebee  but  smaller  than  her  queen  mother. 
These  workers  are  daughters  and  are  happy  in  caring  for  the  growing 
family;  they  gather  pollen  and  nectar  and  add  to  the  mass  of  bee-bread 
for  the  young  to  burrow  in,  meanwhile  the  queen  remains  at  home  and 
devotes  her  energies  to  laying  eggs.  The  workers  not  only  care  for  the 
young,  but  later  they  strengthen  the  silken  pupa  cradles  with  wax,  and 
thus  make  them  into  cells  for  storing  honey.  When  we  understand  that 
the  cells  in  the  bumblebee’s  nest  are  simply  made  by  the  young  bees 
burrowing  in  any  direction,  we  can  understand  why  the  bumblebee  comb 
is  so  disorderly  in  the  arrangement  of  its  cells.  Perhaps  the  boy  of  the 
farm  would  find  the  rank  bumblebee  honey  less  like  the  ambrosia  of  the 
gods  if  he  knew  that  it  was  stored  in  the  deserted  cradles  and  swaddling 
clothes  of  the  bumblebee  grubs.

All  of  the  eggs  in  the  bumblebee  nest  in  the  spring  and  early  summer 
develop  into  workers  which  do  incidentally  the  vast  labor  of  carrying 
pollen  for  thousands  of  flowers ; to  these  only  is  granted  the  privilege  of 
carrying  the  pollen  for  the  red  clover,  since  the  tongues  of  the  other  bees 
are  not  sufficiently  long  to  reach  the  nectar.  The  red  clover  does  not 
produce  seed  in  sufficient  quantity  to  be  a profitable  crop,  unless  there  are 
bumblebees  to  pollinate  its  blossoms.  Late  in  the  summer,  queens  and 
drones  are  developed  in  the  bumblebee  nest,  the  drones,  as  with  the 
honey-bees,  being  mates  for  the  queens.  But  of  all  the  numerous  popula- 
tion of  the  bumblebee  nest,  only  the  queens  survive  the  rigors  of  winter, 
and  on  them  and  their  success  depends  the  future  of  the  bumblebee 
species. 

There  are  many  species  of  bumblebees,  some  much  smaller  than  others, 
but  they  all  have  the  thorax  covered  with  plush  above  and  the  abdomen 
hairy,  and  their  fur  is  usually  marked  in  various  patterns  of  pale  yellow 
and  black.  The  bumblebee  of  whatever  species,  has  short  but  very  active 
antennae  and  a mouth  fitted  for  biting  as  well  as  for  sucking.  Between 
the  large  compound  eyes  are  three  simple  eyes.  The  wings  are  four  in 
number  and  strong ; the  front  legs  are  very  short ; all  the  legs  have  hairs 
over  them  and  end  in  a three-jointed  foot,  tipped  by  a claw.  On  the  hind 
leg,  the  tibia  and  the  first  tarsal  joint  are  enlarged,  making  the  pollen 
baskets  on  which  the  pollen  is  heaped  in  golden  masses.  One  of  the  most 
interesting  observations  possible  to  make,  is  to  note  how  the  bumblebee 
brushes  the  pollen  from  her  fur  and  packs  it  into  her  pollen  baskets.

LESSON  CII 
The  Bumblebee 

Leading  thought — The  bumblebees  are  the  chief  pollen  carriers  for  most 
of  our  wild  flowers  as  well  as  for  the  clovers  and  other  farm  plants.  They 
should,  therefore,  be  kindly  treated  everywhere;  and  we  should  be  careful 
not  to  hurt  the  big  queen  bumblebee  which  we  see  often  in  May. 

Method — Ask  the  questions  and  encourage  the  pupils  to  answer  them 
as  they  have  opportunity  to  observe  the  bumblebees  working  in  the 
powers.  A bumblebee  may  be  imprisoned  in  a tumbler  for  a short  period 
ifor  observation,  and  then  allowed  to  go  unharmed.  It  is  not  advisable  to 
istiHy  the  nest,  which  is  not  only  a dangerous  proceeding  for  the  pupil,  but 
jit  also  means  the  destruction  of  a colony  of  these  very  useful  insects. 
Llowever,  if  the  location  of  a nest  is  discovered,  it  may  be  dug  up  and 
jStudied  after  the  first,  heavy  frost.  Special  stress  should  be  laid  upon  the 
'observations  of  the  actions  of  the  bees  when  visiting  flowers. 

Observations — i.  In  how  many  flowers  do  you  find  the  bumblebee? 
Watch  her  closely  and  see  how  she  gets  the  nectar.  Notice  how  she 
“bumbles  around”  in  a flower  and  becomes  dusted  with  pollen.  Watch 
her  and  note  how  she  gets  the  pollen  off  her  fur  and  packs  it  in  her  pollen 
baskets.  On  which  legs  are  her  pollen  baskets?  How  does  the  pollen 
look  when  packed  in  them?  What  does  she  do  with  pollen  and  nectar? 

2.  Catch  a bumblebee  in  a jelly  glass  and  look  at  her  closely.  Can 
you  see  three  little  eyes  between  the  big  compound  eyes?  Describe  her 
antennae.  Are  they  active?  How  many  pairs  of  wings  has  she?  Do 
you  think  they  are  strong?  Which  pair  of  legs  is  the  shortest?  How 
many  segments  are  there  in  the  leg?  Do  you  see  the  claws  on  the  foot? 

3.  What  is  the  bumblebee’s  covering?  What  is  the  color  of  her 
plush?  Is  she  furry  above  and  below? 

4.  Can  you  see  that  she  can  bite  as  well  as  suck  with  her  mouth-parts  ? 
Will  a bumblebee  sting  a person  unless  she  is  first  attacked? 

5 . Have  you  seen  the  very  large  queen  bumblebee  in  the  spring,  flying 
near  the  ground  hunting  for  a place  to  build  a nest?  Why  must  you  be 
very  careful  not  to  hurt  her  ? How  does  she  pass  the  winter  ? WThat  does 
she  do  first,  in  starting  the  nest? 

6.  In  how  many  ways  does  the  bumblebee  benefit  us?

THE  HONEY-BEE 
Teacher's  Story 

URING  many  years  naturalists  have  been  study- 
ing the  habits  and  adaptations  of  the  honey- 
bees, and,  as  yet,  the  story  of  their  wonderful 
ways  is  not  half  told.  Although  we  know  fairly 
well  what  the  bees  do,  yet  we  have  no  inkling  of 
the  processes  which  lead  to  a perfect  govern- 
ment and  management  of  the  bee  community ; 
and  even  the  beginner  may  discover  things 
never  known  before  about  these  fascinating 
little  workers.  In  beginning  this  work  it  might 
be  well  to  ask  the  pupils  if  they  have  ever  heard  of  a republic  that  has 
many  kings  and  only  one  queen;  and  where  the  citizens  do  all  the 
governing  without  voting,  and  where  the  kings  are  powerless  and  the 
queen  works  as  hard  and  longer  than  any  of  her  subjects;  and  then  tell 
them  that  the  pages  of  history  contain  no  account  of  a republic  so  wonder- 
ful as  this;  yet  the  nearest  beehive  is  the  home  of  just  this  sort  of 
government. 

In  addition  to  the  interest  of  the  bee  colony  from  a nature-study  stand- 
point, it  is  well  to  get  the  children  interested  in  bee-keeping  as  a commer- 
cial enterprise.  A small  apiary  well  managed  may  bring  in  an  acceptable 
income ; and  it  should  be  the  source  of  a regular  revenue  to  the  boys  and 
girls  of  the  farm,  for  one  hive  should  net  the  young  bee-keeper  from  three 
to  five  dollars  per  year  and  prove  a business  education  to  him  in  the  mean- 
time. 

Bees  are  perfect  socialists.  They  have  non-competitive  labor,  united 
capital,  communal  habitations  and  unity  of  interests.  The  bee  commune 
is  composed  of  castes  as  immutable  as  those  of  the  Brahmins,  but  these 
castes  exist  for  the  benefit  of  the  whole  society  instead  of  for  the  individ- 
uals belonging  to  them.  These  castes  we  have  named  queens,  drones  and 
workers,  and  perhaps,  first  of  all,  we  should  study  the  physical  adaptations 
of  the  members  of  these  castes  for  their  special  work  in  the  community. 


The  Worker  (p.446,  Fig.  3.) 

There  are  three  divisions  to  the  body  of  the  bee,  as  in  all  insects — head, 
thorax  and  abdomen.  The  head  bears  the  eyes,  antennae  and  mouth- 
parts,  (p.  448,  W.)  There  are  two  large  compound  eyes  on  either  side 
of  the  head  and  three  simple  eyes  between  them.  The  antennae  arise  from 
the  face,  each  consisting  of  two  parts,  one  straight  segment  at  the  base, 
and  the  end  portion  which  is  curved  and  made  up  of  many  segments. 
There  is  also  a short,  bead-like  segment  where  the  antenna  joins  the  face. 
A lens  is  needed  to  see  the  jaws  of  the  bee,  folded  across,  much  like  a pair  of 
hooks,  and  below  them  the  tongue,  which  is  a sucking  tube ; the  length  of 
the  tongue  is  very  important , for  upon  this  depends  the  ability  of  the  bee  to 
get  nectar  from  the  flowers. 

The  thorax  bears  three  pairs  of  legs  below  and  two  pairs  of  wings 
above.  Each  leg  consists  of  six  segments,  and  the  foot  or  tarsus  has  four 
segments  and  a pair  of  claws.  The  front  leg  has  an  antennae  comb  between 
the  tibia  and  tarsus,  (p.  447,  F,  a,)  the  hind  leg  has  a pollen  basket,  which 
is  a long  cavity  bordered  by  hairs  wherein  the  pollen  is  packed  and  carried 
(p.  447,  A,  pb.)  On  the  other  side  of  the  larse  ioint  beyond  the  pollen 


Handbook  of  N ature-Study 


446 

basket  are  rows  of  spines  which  are  used  to  remove  the  pollen  from  the 
baskets  (p.  447 , B , pc,)  and  between  these  two  large  segments  are  the  pin- 
cers for  removing  the  wax  (p.  447 , B , wp.) 

The  front  pair  of  wings  is  larger  than  the  hind  pair.  The  wings  of  the 
old  bees  that  have  done  much  work  are  always  frayed  at  the  edges. 

There  are  six  segments  or  rings  to  the  abdomen,  plainly  visible  from 
above.  If  the  five  segments  next  the  thorax  are  marked  above  with  yel- 
low bands  on  their  front  edges,  the  bee  is  an  Italian.  On  the  lower  side  of 
the  abdomen,  each  segment  is  made  up  of  a central  plate  with  an  over- 
lapping plate  on  each  side;  just  at  the  front  edge  on  each  side  of  the  cen- 
tral plate  is  a wax  pocket  which  cannot  be  seen  unless  the  bee  is  dissected 
under  a microscope.  From  these  pockets  are  secreted  little  flecks  of  wax 
(p.  448,  X.) 

The  Queen 

The  queen  bee  is  a truly  royal  insect.  She  is  much  larger  than  the 
worker,  her  body  being  long,  pointed,  and  extending  far  beyond  the  tips  of

her  closed  wings,  giving  her  a graceful  form.  She  has  no  pollen  baskets  or 
pollen  comb  upon  her  legs,  because  it  is  not  a part  of  her  work  to  gather 
pollen  or  honey.  The  queen  bee  starts  life  as  an  ordinary  worker  egg.

which  is  selected  for  special  development.  The  workers  tear  down  the 
partitions  of  the  cells  around  the  chosen  egg  and  build  a projection  over 
the  top,  making  an  apartment,  (p.  446,  Fig.  4.)  The  little  white  bee  grub, 
as  soon  as  it  hatches,  is  fed  for  five  days  on  the  same  food  as  is  given  to 
the  worker  grubs  for  three  days;  it  is  a special  substance,  secreted  by  the 
worker  bees,  called  royal  jelly.  This  food  is  very  nourishing,  and  after 
being  reared  upon  it,  the  princess  larva  weaves  around  herself  a silkeri 
cocoon  and  changes  to  a pupa.  Meanwhile  the  workers  have  sealed  her 
cell  with  wax. 


448  Handbook  of  N atur e-Study 

When  the  princess-pupa  changes  to  the  full-grown  queen  she  cuts  a 
circular  door  in  the  cover  of  the  cell  and  pushes  through  it  into  the  world. 
Her  first  real  work  is  to  hunt  for  other  queen  cells  and  if  she  finds  one,  she 
will,  if  not  hindered,  make  a hole  in  its  side  and  sting  to  death  the  poor 
princess  within.  If  she  finds  another  full-grown  queen,  the  two  fight 
until  one  succumbs.  The  queen  never  uses  her  sting  upon  anything  or 
anyone  except  a rival  queen. 

After  a few  days  she  takes  her  marriage  flight  in  the  air,  where  she 
mates  with  some  drone,  and  then  returns  to  her  hive  and  begins  her  great 
work  as  mother  of  the  colony.  She  runs  about  on  the  comb,  pokes  her 
head  into  a cell  to  see  if  it  is  ready,  then  turning  about  thrusts  her  abdomen 
in  and  neatly  glues  an  egg  fast  to  the  bottom. 

When  the  honey  seqson  is  at  its  height  she  works  with  great  rapidity, 
sometimes  laying  at  the  rate  of  six  eggs  per  minute,  often  producing  3,000 
eggs  during  a day,  which  would  equal  twice  her  own  weight.  If  the 
workers  do  not  allow  her  to  destroy  the  other  queens,  she  then  takes  a 
portion  of  her  colony  with  her  and  swarms  out,  seeking  a home  elsewhere.

The  Drone 

The  drone  differs  much  in  shape  from  the  queen  and  the  worker.  He 
is  broad  and  blunt,  being  very  different  in  shape  from  the  queen,  and 
larger  than  the  worker,  (p.  446,  Fig.  2.)  He  has  no  pollen  baskets  on  his  legs 
and  has  no  sting.  His  eyes  are  very  much  larger  than  those  of  the  queen 
or  the  worker  and  unite  at  the  top  of  the  head  (p.  448,  D.)  His  wings 
are  larger  and  stronger  than  those  of  the  worker  or  queen.  It  is  not  his 
business  to  go  out  and  gather  honey  or  to  hplp  in  the  wort  of  the  hive. 
His  tongue  is  not  long  enough  to  get  honey  from  the  flowers;  he  has  no 
pollen  basket  in  which  to  carry  pollen ; he  has  no  sting  to  fight  enemies 
and  no  pockets  for  seer  ting  wax ; he  is  fed  by  his  sister  wo  kers  until  the 
latter  part  of  the  season  when  the  honey  supply  runs  low,  and  then  he  is 
stung  or  bitten  to  death  by  these  same  sisters  who  have  always  given  him 
such  good  care.  The  drone  should  be  called  a prince  or  king,  since  his 
particular  office  in  the  hive  is  to  mate  with  the  queen.

LESSON  CIII 
The  Honey-bee 

Leading  thought — In  a colony  of  honey-bees  there  are  three  different, 
forms  of  bees,  the  queens,  the  drones,  and  the  workers.  All  of  these 
have  their  own  special  work  to  do  for  the  community. 

Method— In  almost  every  country  or  village  community  there  is  an 
apiary,  or  at  least  someone  who  keeps  a few  colonies  of  bees ; to  such  the 
teacher  must  turn  for  material  for  this  lesson.  If  this  is  not  practical  the 
teacher  may  purchase  specimens  from  any  bee  dealer ; she  may,  for  in- 
stance, get  an  untested  queen  with  attendant  workers  in  a queen  cage  sent 
by  mail  for  a small  sum.  These  could  be  kept  alive  for  some  time  by 
feeding  them  with  honey,  during  which  time  the  pupils  can  study  the 
forms  of  the  two  castes.  Any  apiary  during  September  will  give  enough 
dead  drones  for  a class  to  observe.  Although  ordinarily  we  do  not  advo- 
cate the  study  of  dead  specimens,  yet  common  sense  surely  has  its  place 
in  nature-study;  and  in  the  case  of  the  honey-bee,  a closer  .study  of  the 
form  of  the  insect  is  desirable  than  the  living  bee  might  see  fit  to  permit. 
There  are  no  more  wonderful  instances  of  adaptation  of  form  to  life  than 
is  found  in  the  anatomy  of  the  workers,  queens  and  drones;  moreover,  it 
is  highly  desirable  if  the  pupils  are  ever  to  become  bee-keepers,  that  they 
shall  know  these  adaptations. 

A lens  is  almost  necessary  for  these  lessons  and  a compound  microscope 
used  with  a low  power  would  be  a very  desirable  adjunct.  This  lesson 
should  not  be  given  below  the  fifth  grade;  and  it  is  better  adapted  to 
eighth  grade  work. 

The  Worker 

Observations — 1.  How  many  divisions  of  the  body  are  there? 

2.  What  organs  are  borne  on  the  head?

what  means  it  occurs.

Honey-comb 


Teacher's  Story 

HE  structure  of  honey-comb  has  been  for  ages 
admired  by  mathematicians,  who  have  meas- 
ured the  angles  of  the  cells  and  demonstrated 
the  accurate  manner  in  which  the  rhomb- 
shaped cell  changes  at  its  base  to  a three  faced 
pyramid;  and  proven  that,  considering  the 
material  of  construction,  honey-comb  exem- 
plifies the  strongest  and  most  economic  struc- 
ture possible  for  the  storing  of  liquid  contents. 
While  recent  instruments  of  greater  precision 
in  measuring  angles,  show  less  perfection  in 
honey-comb  than  the  ancients  believed,  yet  the  fact  still  stands  that 
the  general  plan  of  it  is  mathematically  excellent. 

Some  have  tried  to  detract  from  bee  skill,  by  stating  that  the  six-sided 
cell  is  simply  the  result  of  crowding  cells  together.  Perhaps  this  was  the 
remote  origin  of  the  hexagonal  cell ; but  if  we  watch  a bee  build  her  comb, 
we  find  that  she  begins  with  a base  laid  out  in  triangular  pyramids,  on 
either  side  of  which  she  builds  out  six-sided  cells.  A cell  just  begun,  is  as 
distinctly  six-sided  as  when  completed. 

The  shape  of  the  cell  of  a honey-comb  is  six-sided  in  cross  section. 
The  bottom  is  a three-sided  pyramid  and  its  sides  help  form  pyramids 
at  the  bottom  of  the  cells  opposite,  thus  economizing  every  particle  of 
space.  In  the  hive,  the  cells  lie  horizontal  usually,  although  sometimes 
the  combs  are  twisted. 

The  honey  is  retained 
in  the  cell  by  a cap  of 
wax  which  is  made  in  a 
very  cunning  fashion; 
it  consists  o±  a cir- 
cular disc  at  the  mid- 
dle supported  from 
the  six  angles  of  the 
cell  by  six  tiny  girders. 

The  comb  is  made  fast 
to  the  section  of  the 
hive  by  being  plas- 
tered upon  it.  The 
foundation  comb  sold 
to  apiarists  is  quite 
thick,  so  that  the 
edges  of  the  cell  may 
be  drawn  out  and  al- 
most complete  the 
sides  of  the  cell. 

However,  the  founda- 
tion comb  is  expensive  and  is  ordinarily  used  by  the  bee-keeper  simply  as 
a starter,  which  means  a little  strip  a few  inches  or  so  in  width  fastened 
to  the  top  of  a section  just  to  give  the  bees  a hint  that  this  is  the  direction 
in  which  the  comb  should  be  built,  a hint  which  the  bees  invariably  take.

The  cells  of  honey-comb  are  used  also  for  the  storing  of  bee-bread  and  also 
as  cradles  for  the  young  bees.

sections  show  the  work  of  the  bees  in  drawing  out  and 
building  on  the  "starters.” 


LESSON  CIV 
The  Honey-comb 

Leading  thought — The  cells  of  honey-comb  are  s;x-sided  and  in  double 
rows  and  are  very  perfectly  arranged  for  the  storing  of  honey,  so  as  to  save 
room. 

Materials — A section  filled  with  honey  and  also  a bit  of  empty  comb 
and  a bit  of  commercial  foundation  comb  which  may  be  obtained  in 
any  apiary. 

Observations — i . Look  at  a bit  of  empty  honey-comb ; what  is  the 
shape  of  the  cell  as  you  look  down  into  it? 

2.  What  is  the  shape  of  the  bottom  of  the  cell? 

3.  How  does  the  bottom  of  the  cell  join  the  bottom  of  the  cell  oppo- 
site ? Explain  how  honey-comb  economizes  space  as  storage  for  honey, 
and  why  an  economy  of  space  is  of  use  to  bees  in  the  wild  state. 

4.  In  the  hive  is  the  honey-comb  placed  so  that  the  length  of  the  cells 
are  horizontal  or  up  and  down? 

5 . Observe  honey-comb  containing  honey ; how  is  the  honey  retained 
in  the  cells  ? 

6.  Carefully  take  off  a cap  from  the  honey  cell  and  see  if  you  can 
find  the  six  girders  that  extend  inward  from  the  angles  of  the  cell  to 
support  the  circular  portion  in  the  center. 

7.  By  what  means  is  the  honey-comb  made  fast  .to  the  sides  of  the 
section  or  the  hive? 

8.  Study  a bit  of  foundation  comb  and  note  where  the  bees  will  pull 
out  the  wax  to  form  the  cell. 

9.  Why  and  how  is  foundation  comb  used  by  the  bee-keeper? 

10.  For  what  purpose  besides  storing  honey  are  the  cells  of  honey- 
comb used  by  the  bees?

INDUSTRIES  OF  THE  HIVE  AND  THE  OBSERVATION  HIVE 

Teacher's  Story 

EE-hives  are  the  houses  which  man  furnishes  for 
the  bee  colonies,  the  wild  bees  ordinarily  living 
in  hollow  trees  or  in  caves.  The  usual  hive 
consists  of  a box  which  is  the  lower  story  and 
of  one  or  more  upper  stories,  called  “supers.” 
In  the  lower  story  are  placed  frames  for  the1 
brood  and  for  storing  the  honey  for  the  winter 
use  of  the  bees.  In  the  supers  are  placed  the 
sections,  each  of  which  is  planned  to  hold  a 
pound  of  honey.  It  is  the  habit  of  the  bees  to 
place  their  brood  in  the  lower  part  of  their 
nests  and  store  honey  in  the  upper  portions. 
The  bee-keepers  have  taken  advantage  of  this  habit  of  the  bees  and 
remove  the  supers  with  their  filled  sections  and  replace  them  with  others 
to  be  filled,  and  thus  get  a large  crop  of  honey.  The  number  of  bees  in  a 
colony  varies;  there  should  be  at  least  40,000  in  a healthy  colony.  Of 
these  a large  proportion  are  workers ; there  may  be  a few  hundred  drones 
the  latter  part  of  the  season  but  only  one  queen. 

Honey-comb  is  built  of  wax  and  is  hung  from  the  frame  so  that  the 
cells  are  horizontal ; its  purpose  is  to  cradle  the  young  and  for  the  storage 
of  pollen  and  honey.  The  wax  used  for  building  the  comb  is  a secretion 
of  the  bees;  when  comb  is  needed,  a number  of  self -elected  bee  citizens 
gorge  themselves  with  honey  and  hang  themselves  up  in  a curtain,  each 
bee  reaching  up  with  her  fore  feet  and  taking  hold  of  the  hind  feet  of  the 
one  above  her.  After  remaining  thus  for  some  time  the  wax  appears  in 
little  plates,  one  on  each 
side  of  the  second, 
third,  fourth  and  fifth 
segments  of  the  abdo- 
men. This  wax  is 
chewed  by  the  bees 
and  made  into  comb. 

Honey  is  made  from 
the  nectar  of  flowers 
which  the  bee  takes 
into  her  honey  stom- 
ach. This,  by  the  way, 
is  not  the  true  stomach 
of  the  bee  and  has 
nothing  to  do  with 
digestion.  It  is  simply 
a receptacle  for  storing 
the  nectar,  which  is 
mixed  with  some  secre- 
tion from  the  glands  of 
the  bee  which  brings 
about  chemical 
changes,  the  chief  of 
which  is  changing  the 


A home-made  observation  hive.

cane  sugar  of  the  nectar  into  the  more  easily  digested  grape  sugar  of 
the  honey.  After  the  honey  is  emptied  from  the  honey  stomach  into 
the  cell,  it  remains  exposed  to  the  air  for  some  time  before  the  cell  is 
capped,  and  thus  ripens.  It  is  an  interesting  fact  that  up  to  the  seven- 
teenth century  honey  was  the  only  means  people  had  for  sweetening 
their  food,  as  sugar  was  unknown. 

Bee-bread  is  made  from  the  pollen  of  flowers  which  is  perhaps 
mixed  with  saliva  so  as  to  hold  together;  it  is  carried  from  the 
field  on  the  pollen  baskets  of  the  hind  legs  of  the  workers;  it  is 
packed  into  the  cell  by  the  bees  and  is  used  for  food.  Propolis 
is  bee  glue;  it  is  used  as  a cement  and  varnish;  it  is  gathered  by 
the  bees  -from  the  leaf-buds  of  certain  trees  and  plants,  although 
when  they  can  get  it,  the  bees  will  take  fresh  varnish.  It  is  used  as 
a filler  to  make  smooth  the  rough  places  of  the  hive ; it  often  helps  hold 
the  combs  in  place ; it  calks  every  crack ; it  is  applied  as  a varnish  to  the 
cells  of  the  honey-comb  if  they  remain  unused  for  a time,  and  if  the  door  of 
the  observation  hive  be  left  open  the  bees  will  cover  the  inside  of  the  glass 
with  this  glue,  and  thus  make  the  interior  of  the  hive  dark. 

The  young  bees  are  footless,  white  grubs.  Each  one  lives  in  its  own 
little  cell  and  is  fed  by  the  nurse  bees,  which  giv$  it  partly  digested  food 
from  their  own  stomachs. 

The  removal  of  honey  from  the  supers  does  not  do  any  harm  to  the  bee 
colony  if  there  is  enough  honey  left  in  the  brood  chambers  to  support  the 
bees  during  the  winter.  There  should  be  twenty-five  or  thirty  pounds  of 
honey  left  in  the  brood  chamber  for  winter  use.  In  winter,  the  hives 
should  be  protected  from  the  cold  by  being  placed  in  special  houses  or  by 
being  encased  in  larger  boxes,  leaving  an  opening  so  that  the  bees  may 
come  out  in  good  weather.  The  chaff  hive  is  best  for  both  winter  and 
summer,  as  it  surrounds  the  hive  with  a space,  which  is  filled  with  chaff, 
and  keeps  the  hive  warm  in  winter  and  cool  in  summer.  Many  bee- 
keepers put  their  bees  in  cellars  during  the  winter,  but  this  method  is  not 
as  safe  as  the  chaff  hive.  Care  should  be  taken  in  summer  to  place  the 
hives  so  that  they  are  shaded  at  least  part,  of  the  day.  The  grass  should 
be  mown  around  the  hives  so  that  the  bees  will  not  become  entangled  in  it, 
as  they  return  from  the  fields  laden  with  honey. 

What  may  be  seen  in  the  observation  hive — First  of  ail,  it  is  very 
interesting  to  watch  the  bees  build  their  comb.  When  more  comb  is 
needed  Certain  members  of  the  colony  gorge  themselvbs  with  honey  and 
remain  suspended  while  it  oozes  out  of  the  wax  pockets  on  the  lower  side 
of  the  abdomen.  This  wax  is  collected  and  chewed  to  make  it  less  brittle 
and  then  is  carried  to  the  place  where  the  comb  is  being  built  and  is 
molded  into  shape  by  the  jaws  of  the  workers.  However,  the  bee  that 
puts  the  wax  in  place  is  not  always  the  one  that  molds  it  into  comb. 

A bee  cbmes  into  the  hive  with  her  honey  stomach  filled  with  nectar 
and  disgorges  this  into  a cell.  Whefn  a bee  comes  in  loaded  with  pollen,  she 
first  brushes  it  from  the  pollen  baskets  on  her  hind  legs  into  the  cell; 
later  another  worker  comes  along  and  packs  the  pollen  grains  into  the  cell 
with  her  head,  which  is  a comical  sight. 

The  bee  nurses  run  about  on  the  cdrnb  feeding  the  young  bee  grubs 
partially  digested  honey  and  pollen  regurgitated  from  their  own  stomachs 
Whenever  the  queen  moves  about  the  comb  she  is  followed  by  a retinue  of 
devoted  attendants  which  feed  her  on  the  rich  and  perfectly  digested  royal 


Insect  Study

jelly  and  also  take  care 
of  her  royal  person  and 
give  her  every  atten- 
tion possible.  The 
queen,  when  laying, 
thrusts  her  abdomen 
into  the  cell  and  glues  a 
little  white  egg  to  the 
bottom.  The  specially 
interesting  thing  about 
this  is  that  the  queen 
always  lays  an  egg 
which  will  produce  a 
female,  or  worker  in  the 
smaller  cells  and  will 
always  lay  an  egg  to  produce  a drone  or  male  in  the  larger  cells. 

If  there  is  any  foreign  substance  in  the  observation  hive  it  is  interesting 
to  see  the  bees  go  to  work  at  once  to  remove  it.  They  dump  all  of  the 
debris  out  in  front  of  the  hive.  They  close  all  crevices  in  the  hive;  and 
they  will  always  curtain  the  glass,  if  the  door  is  kept  open  too  much,  with 
propolis  or  bee  glue,  which  is  a very  sticky  substance  which  they  get  from 
leaf  buds  and  other  vegetable  sources.  When  bees  fan  to  set  up  a current 
of  air  in  the  hive,  they  glide  back  and  forth,  moving  the  wings  so  rapidly 
that  we  can  only  see  a blur  about  their  bodies. 

If  drones  are  developed  in  the  hive,  it  is  interesting  to  see  how  tenderly 
they  are  fed  by  their  sister  workers,  although  they  do  not  hesitate  to  help 
themselves  to  the  honey  stored  in  the  cells ; and  if  the  observation  hive  is 
working  during  September,  undoubtedly  the  pupils  may  be  able  to  see  the 
murder  of  the  drones  by  their  sisters.  But  the  children  should  understand 
that  this  killing  of  the  drones  is  necessary  for  the  preservation  of  the 
colony,  as  the  workers  cannot  store  enough  honey  to  keep  the  colony  alive 
during  the  winter  if  the  drones  were  allowed  to  go  on  feeding. 

If  you  see  the  worker  bees  fighting,  it  means  that  robbers  are  attempt- 
ing to  get  at  the  stores  of  the  observation  hive.  The  entrance  to  the  hive 
should  at  once  be  contracted  by  placing  a block  of  wood  in  front,  so  that 
there  is  room  for  only  one  bee  at  a time  to  pass  in  and  out. 

LESSON  CV 

The  Industries  of  the  Hive 

Leading  thought — In  the  hive  are  carried  on  the  industries  of  wax- 
making, building  of  honey-comb,  storing  of  honey  and  bee-bread,  caring 
for  the  young,  keeping  the  hive  clean  and  ventilated  and  calking  all 
crevices  with  bee  glue. 

Method — This  lesson  should  be  in  the  nature  of  a demonstration.  If 
there  is  an  apiary  in  the  neighborhood,  it  is  quite  possible  that  the  teacher 
may  show  the  pupils  a hive  ready  for  occupancy  by  the  bees ; in  any  case 
she  will  have  no  difficulty  in  borrowing  a frame  of  brood  comb,  and  this 
with  a section  of  honey  which  can  be  bought  at  the  grocery  store,  is 
sufficient  if  there  is  no  observation  hive.  This  lesson  should  be  an  in- 
formal talk  between  teacher  and  pupils.

An  observation  hive  in  the  schoolroom  is  an  object  of  greatest  interest 
to  the  pupils,  as  through  its  glass  sides  they  may  be  able  to  verify  for 
themselves  the  wonderful  tales  concerning  the  lives  and  doings  of  the  bees 
which  have  been  told  us  by  naturalists.  Moreover,  the  study  thus  made 
of  the  habits  of  the  bees  is  an  excellent  preparation  for  the  practical 
apiarist,  and  we  sincerely  believe  that  bee-keeping  is  one  of  the  ways  by 
which  the  boys  and  girls  of  the  farm  may  obtain  money  for  their  own  use. 

The  observation  hive  is  very  simply  constructed  and  can  be  made  by 
anyone  who  knows  how  to  use  ordinary  carpenter  tools.  It  is  simply 
a small,  ordinary  hive  with  a pane  of  glass  on  each  side  which  is  covered 
by  a hinged  door.  A hive  thus  made  is  placed  so  that  the  front  end 
rests  upon  a window  sill ; the  sash  is  lifted  an  inch  or  so,  a strip  of  wood,  or 
a piece  of  wire  netting  being  inserted  underneath  the  sash  except  in  front 
of  the  entrance  of  the  hive,  to  hinder  the  bees  from  coming  back  into  the 
room.  A covered  passageway  should  extend  from  the  entrance  of  the 
hive  to  the  outside  of  the  window  sill.  This  window  should  be  one  which 
opens  away  from  the  playground  so  that  the  bees  coming  and  going,  will 
not  come  into  collision  with  the  pupils.  The  observation  window  should 
De  kept  carefully  shut,  except  when  the  pupils  are  using  it,  since  the  bees 
object  to  light  in  their  homes. 

The  A.  I.  Root  Co.,  of  Medina,  Ohio,  sell  a pretty  observation  hive 
which  we  have  used  successfully  by  stocking  it  afresh  each  season,  it  being 
too  small  for  a self-sustaining  colony.  But  it  has  the  advantage  of  small- 
ness which  enables  us  to  see  all  that  is  going  on  within  it,  which  would  be 
impossible  in  a larger  hive.  This  hive  comes  in  several  sizes,  and  will  be 
shipped  from  the  makers  stocked  with  bees  at  prices  ranging  from  $1.25  to 
$4.00. 

Observations — Industries  and  care  of  the  hive — 1 . What  is  the  hive,  and 
what  do  wild  bees  use  instead  of  the  hive?  Describe  as  follows:

9.  How  young  bees  look  and  how  they  are  cradled  and  fed. 

10.  Does  the  removal  of  the  honey  from  the  supers  in  the  fall  do  any 
harm  to  the  bee  colony? 

11.  How  much  honey  should  a good-sized  colony  have  in  the  fall  to 
winter  well?

16.  Describe  how  the  nurse  bees  feed  the  young,  and  how  the  young 
look  when  eating. 

17.  Describe  how  the  “ladies  in  waiting”  feed  and  care  for  the  queen.

THE  GARDEN  SNAIL 
Teacher's  Story 

b 'A  ERCHANCE  if  those  who  speak  so  glibly  of  a “snail’s  pace**' 
JLJSf ,,  should  study  it,  they  would  not  sneer  at  it,  for  carefully 
observed,  it  seems  the  most  wonderful  method  of  locomotion 
ever  devised  by  animal.  Naturally  enough,  the  snail  can- 
p i\.'  not  gallop  since  it  has  but  one  foot ; but  it  is  safe  to  assert 

that  this  foot,  which  is  the  entire  lower  side  of  the  body,  is  a 
remarkable  organ  of  locomotion.  Let  a snail  crawl  up  the  side  of  a 
tumbler  and  note  how  this  foot  stretches  out  and  holds  on.  It  has 
flanges  along  the  sides,  which  secrete  an  adhesive  substance  that  enables 
the  snail  to  cling,  and  yet  it  also  has  the  power  of  letting  go  at  will.  The 
slow,  even,  pushing  forward  of  the  whole  body,  weighted  by  the  un- 
balanced shell,  is  as  mysterious  and  seemingly  as  inevitable,  as  the  march 
of  fate,  so  little  is  the  motion  connected  with  any  apparent  muscular 
effort.  But  when  his  snailship  wishes  to  let  go  and  retire  from  the  world, 
this  foot  performs  a feat  which  is  certainly  worthy  of  a juggler;  it  folds 
itself  lengthwise,  and  the  end  on  which  the  head  is  retires  first  into  the 
shell,  the  tail  end  of  the  foot  being  the  last  to  disappear.  And  now  find 
your  snail ! 

Never  was  an  animal  so  capable  of  stretching  out  and  then  folding  up 
all  its  organs,  as  is  this  little  tramp  who  carries  his  house  with  him.  Turn 
one  on  his  back  when  he  has  withdrawn  into  his  little  hermitage,  and 
watch  what  happens.  Soon  he  concludes  he  will  find  out  where  he  is,  and 
why  he  is  bottomside  up ; as  the  first  evidence  of  this,  the  hind  end  of  the 
foot,  which  was  folded  together,  pushes  forth ; then  the  head  and  horns 
come  bubbling  out.  The  horns  are  not  horns  at  all,  but  each  is  a stalk 
bearing  an  eye  on  the  tip.  This  is  arranged  conveniently,  like  a marble 
fastened  to  the  tip  of  a glove  finger.  When  a snail  wishes  to  see,  it 
stretches  forth  the  stalk  as  if  it  were  made  of  rubber;  but  if  danger  is  per- 
ceived, the  eye  is  pulled  back  exactly  as  if  the  marble  were  pulled  back 
through  the  middle  of  the  glove  finger;  or  as  a boy  would  say,  “it  goes 
into  the  hole  and  pulls  the  hole  in  after  it.”  Just  below  the  stalked  eyes, 
is  another  pair  of  shorter  horns,  which  are  feelers,  and  which  may  be 
drawn  back  in  the  same  manner ; they  are  used  constantly  for  testing  the 
nature  of  the  surface  on  which  the  snail  is  crawling.  It  is  an  interesting 
experiment  to  see  how  near  to  the  eyes  and  the  feelers  we  can  place  an 
object,  before  driving  them  back  in.  With  these  two  pairs  of  sense 
organs  pushed  out  in  front  of  him,  the  snail  is  well  equipped  to  observe 
the  topography  of  his  immediate  vicinity ; if  he  wishes  to  explore  above, 
he  can  stand  on  the  tip  of  his  tail  and  reach  far  up ; and  if  there  is  any- 
thing to  take  hold  of,  he  can  glue  his  toe  fast  to  it  and  pull  himself  up. 
Moreover,  I am  convinced  that  snails  have  decided  views  about  where 
they  wivSh  to  go,  for  I have  tried  by  the  hour  to  keep  them  marching  length- 
wise on  the  piazza  railing,  so  as  to  study  them;  and  every  snail  was 
determined  to  go  crosswise  and  crawl  under  the  edge,  where  it  was  nice 
and  dark.

It  is  interesting  to  observe  through  a lens,  the  way  a snail  takes  his 
dinner;  place  before  him  a piece  of  sweet  apple  or  other  soft  fruit,  and  he 
will  lift  himself  on  his  front  toe  and  begin  to  work  his  way  into  the  fruit.

breathing-pore;  3.  Prospecting. 


He  has  an  efficient  set  of 
upper  teeth,  which  look  like 
a saw  and  are  colored  as  if  he 
chewed  tobacco;  with  these 
teeth  and  with  his  round 
tongue,  which  we  can  see 
popping  out,  he  soon  makes 
an  appreciable  hole  in  the 
pulp;  but  his  table  manners 
are  not  nice,  since  he  is  a hope- 
less slobberer. 

There  are  right  and  left 
spiraled  snails.  All  those  ob- 
served for  this  lesson  show  the 
spiral  wound  about  the  center 
from  left  over  to  right,  or  in 
the  direction  of  the  movement 
of  the  hands  of  a clock,  ana 
this  is  usually  the  case.  With 
the  spiral  like  this,  the  breath- 
ing pore  is  on  the  right  side  of 
the  snail  and  may  be  seen  as 
an  opening  where  the  snail 
joins  the  shell.  This  pore 
may  be  seen  to  open  and  con- 
tract slowly;  by  this  motion, 
the  air  is  sucked  into  the  shell 
where  it  bathes  the  snail’s 
lung,  and  is  then  forced  out — • 
a process  very  similar  to  our 
own  breathing. 

The  snail  has  good  judg- 
ment when  attacked;  at  the 
first  scare,  he  simply  draws  in 
his  eyes  and  feelers  and  with- 
draws his  head,  so  that  noth- 
ing can  be  seen  of  him  from 
above,  except  a hard  shell 
which  would  not  attract  the 
passing  bird.  But  if  the  at- 
tack continues,  he  lets  go  all 
hold  on  the  world,  and  noth- 
ing can  be  seen  of  him  but  a 
little  mass  which  blocks  the 
door  to  his  house ; and  if  he  is 


obliged  to  experience  a drought,  he  makes  a pane  of  glass  out  of  mucus 
across  his  door,  and  thus  stops  evaporation.  This  is  a very  wise  precau- 
tion, because  the  snail  is  made  up  largely  of  moisture  and  much  water  is 
needed  to  keep  his  mucilage  factory  running. 


460 


Handbook  of  N atur  e-Study 


The  way  the  snail  uses  his  eyes  is  comical ; he  goes  to  the  edge  of  a leaf 
and  pokes  one  eye  over  to  see  what  the  new  territory  is  like ; but  if  his  eye 
strikes  an  object,  he  pulls  that  one  back,  and  prospects  for  a time  with  the 
other.  He  can  lengthen  the  eye-stalk  amazingly  if  he  has  need.  How 
convenient  for  us  if  we  could  thus  see  around  a corner.  If  a small  boy  were 
as  well  off  as  a snail,  he  could  see  the  entire  ball  game  through  a knot-hole 
in  the  fence.  In  fact,  the  more  we  study  the  snail,  the  more  we  admire, 
first  his  powers  of  ascertaining  what  there  is  in  the  world,  and  then  his 
power  of  getting  around  in  the  world  by  climbing  recklessly  and  relent- 
lessly over  obstacles,  not  caring  whether  he  is  right  side  up  on  the  floor  or 
hanging  wrong  side  up  from  the  ceiling;  and,  finally,  we  admire  his  utter 
reticence  when  things  do  not  go  to  suit  him.  I think  the  reason  I always 
call  a snail  “he”  is  because  he  seems  such  a philosopher — a Diogenes  in  his 
tub.  However,  since  the  snail  combines  both  sexes  in  one  individual  the 
pronoun  is  surely  applicable. 

■ When  observed  through  a lens,  the  snail’s  skin  looks  like  that  of  the 
alligator,  rough  and  divided  into  plates,  with  a surface  like  pebbled 
leather ; and  no  insect  intruder  can  crawl  up  his  foot  and  get  into  the  shell 
“unbeknownst,”  for  the  shell  is  grown  fast  to  the  flange,  that  grows  out  of 
the  middle  of  the  snail’s  back.  The  smoother  the  surface  the  snail  is 
crawling  upon,  the  harder  to  make  him  let  go.  The  reason  for  this  lies  in 
the  mucus,  which  he  secretes  as  he  goes,  and  which  enables  him  to  fasten 
himself  anywhere ; he  can  crawl  up  walls  or  beneath  any  horizontal  sur- 
face, shell  downward,  and  he  leaves  a shining  trail  behind  him  wherever 
he  goes. 

Snail  eggs  are  as  large  as  small  peas,  almost  transparent,  covered  with 
very  soft  shells,  and  fastened  together  by  mucus.  They  are  laid  under 
stones  and  decaying  leaves.  As  soon  as  the  baby  snail  hatches,  it  has  a 
shell  with  only  one  spiral  turn  in  it;  as  it  grows,  it  adds  layer  after  layer 
to  the  shell  on  the  rim  about  the  opening---which  is  called  the  lip ; these 
layers  we  can  see  as  ridges  on  the  shell.  If  we  open  an  empty  shell,  we 
can  see  the  progress  of  growth  in  the  size  of  the  spirals.  Snails  eat  suc- 
culent leaves  and  other  soft  vegetable  matter.  During  the  winter,  they 
bury  themselves  beneath  objects  or  retire  into  soft  humus.  In  preparing 
for  the  winter,  the  snail  makes  a door  of  mucus  and  lime,  or  sometimes 
three  doors,  one  behind  another,  across  the  entrance  to  his  shell,  leaving  a 
tiny  hole  to  admit  the  air.  There  are  varieties  of  snails  which  are  eaten 
as  dainties  in  Europe,  and  are  grown  on  snail  farms  for  the  markets.  The 
species  most  commonly  used  is  the  same  as  that  which  was  regarded  as  a 
table  luxury  by  the  ancient  Romans.

LESSON  CVI 
The  Garden  Snail 

Leading  thought — The  snail  carries  his  dwelling  with  nun,  and  retires 
within  it  in  time  of  danger.  He  can  climb  on  any  smooth  surface. 

Method — The  pupils  should  make  a snailery,  which  may  consist  of  any 
glass  jar,  with  a little  soil  and  some  moss  or  leaves  at  the  bottom,  and  a 
shallow  dish  of  water  at  one  side.  The  moss  and  soil  should  be  kept  moist. 
Place  the  snails  in  this  and  give  them  fresh  leaves  or  pulpy  fruit,  and  they 
will  live  comfortably  in  confinement.  A bit  of  cheese-cloth  fastened  with 


Other  Invertebrate- Animal  Study 


461 


a rubber  band  should  be  placed  over  the  top  of  the  jar.  A tumbler  in- 
verted over  a dish,  on  which  is  a leaf  or  two,  makes  a good  observa- 
tion cage  to  pass  around  the  room  for  closer  examination.  An  empty  shell 
should  be  at  hand,  which  may  be  opened  and  examined. 

Observations — 1.  Where  do  you  find  snails?  Why  do  they  like  to 
live  in  such  places? 

2.  How  does  a snail  walk?  Describe  its  “foot.”  How  can  it  move 
with  only  one  foot?  Describe  how  it  climbs  the  side  of  the  glass  jar. 
How  does  it  cling? 

3 . What  sort  of  a track  does  a snail  leave  behind  it  ? What  is  the  use 
of  this  mucus? 

4.  Where  are  the  snail’s  eyes?  Why  is  this  arrangement  convenient  ? 
If  we  touch  one  of  the  eyes  what  happens?  What  advantage  is  this  to 
the  snail?  Can  it  pull  in  one  eye  and  leave  the  other  out? 

5.  Look  below  the  eyes  for  a pair  of  feelers.  What  happens  to  these 
if  you  touch  them? 

6.  What  is  the  use  of  its  shell  to  a snail?  What  does  the  snail  do  if 
startled  ? If  attacked  ? When  a snail  is  withdrawn  into  its  shell  can  you 
see  any  part  of  the  body?  Is  the  shell  attached  to  the  middle  of  the  foot? 
How  did  the  shell  grow  on  the  snail’s  back?  How  many  spiral  turns  are 
there  in  the  full-grown  shell  ? Are  there  as  many  in  the  shell  of  a young 
snail?  Can  you  see  the  little  ridges  on  the  shell?  Do  you  think  that 
these  show  the  way  the  shell  grew? 

7 . Can  you  find  the  opening  through  which  the  snail  draws  its  breath  ? 
Where  is  this  opening?  Describe  its  action. 

8.  Put  the  snail  in  a dry  place  for  two  or  three  days,  and  see  what 
happens.  Do  you  think  this  is  for  the  purpose  of  keeping  in  moisture? 
What  does  the  snail  do  during  the  winter? 

9.  Place  a snail  on  its  back  and  see  how  it  rights  itself . Describe  the 
way  it  eats.  Can  you  see  the  horny  upper  jaw?  Can  you  see  the  rasping 
tongue?  What  do  snails  live  on? 

10.  Do  you  know  how  the  snail  eggs  look  and  where  they  are  laid? 
How  large  is  the  shell  of  the  smallest  garden  snail  you  ever  saw?  How 
many  spiral  turns  were  there  in  it?  Open  an  empty  snail  shell  and  see 
how  the  spirals  widened  as  the  snail  grew.  Do  you  think  the  shell  grew 
by  layers  added  to  the  lip? 

11.  Do  all  snails  have  shells?  Describe  all  the  kinds  of  snails  you 
know.  What  people  consider  snails  a table  delicacy?

THE  EARTHWORM 

Teacher's  Story 

LTHOUGH  not  generally  considered  attractive, 
for  two  reasons  the  earthworm  has  an  impor- 
tant place  in  nature-study:  it  furnishes  an 

interesting  example  of  lowly  organized  crea- 
tures, and  it  is  of  great  economic  importance 
to  the  agriculturist.  The  lesson,  should  have 
special  reference  to  the  work  done  by  earth- 
worms and  to  the  simplicity  of  the  tools  with 
which  the  work  is  done. 

The  earthworm  is,  among  lower  animals, 
essentially  the  farmer.  Long  before  man  con- 
ceived the  idea  of  tilling  the  soil,  this  seemingly 
insignificant  creature  was  busily  at  work 
plowing,  harrowing,  and  fertilizing  the  land.  Nor  did  it  overlook 
the  importance  of  drainage  and  the  addition  of  amendments — 
factors  of  comparatively  recent  development  in  the  management  of  the 
soil  by  man. 

Down  into  the  depths,  sometimes  as  far  as  seven  or  eight  feet,  but 
usually  from  twelve  to  eighteen  inches,  goes  the  little  plowman,  bringing 
to  the  surface  the  subsoil,  which  is  exactly  what  we  do  when  we  plow 
deeply.  To  break  up  the  soil  as  our  harrows  do,  the  earthworm  grinds  it 
in  a gizzard  stocked  with  grains  of  sand  or  fine  gravel,  which  act  as  mill- 
stones. Thus  it  turns  out  soil  of  much  finer  texture  than  we,  by  harrow- 
ing or  raking,  can  produce.  In  its  stomach  it  adds  the  lime  amendment, 
so  much  used  by  the  modern  farmer.  The  earthworm  is  apparently  an 
adept  in  the  use  of  fertilizers ; it  even  shows  discrimination  in  keeping  the 
organic  matter  near  the  surface,  where  it  may  be  incorporated  into  the 
soil  of  the  root  zone.  It  drags  into  its  burrows  dead  leaves,  flowers  and 
grasses,  with  which  to  line  the  upper  part.  Bones  of  dead  animals,  shells, 
and  twigs  are  buried  by  it,  and,  being  more  or  less  decayed,  furnish  food 
for  plants.  These  minute  agriculturists  have  never  studied  any  system 
of  drainage,  but  they  bore  holes  to  some  depth  which  carry  off  the  surplus 
water.  They  plant  seeds  by  covering  those  that  lie  on  the  ground  with 
soil  from  below  the  surface — good,  enriched,  well  granulated  soil  it  is,  too. 
They  further  care  for  the  growing  plants  by  cultivating,  that  is  keeping 
fine  and  granular,  the  soil  about  the  roots. 

It  was  estimated  by  Darwin  that,  in  garden  soil  in  England,  there  are 
more  than  50,000  earthwQrms  in  an  acre,  and  that  the  whole  superficial 
layer  of  vegetable  mold  passes  through  their  bodies  in  the  course  of  every 
few  years,  at  the  rate  of  eighteen  tons  per  acre  yearly. 

This  agricultural  work  of  the  earthworm  has  been  going  on  for  ages. 
Wild  land  owes  much  of  its  beauty  to  this  diminutive  creature  which 
keeps  the  soil  in  good  condition.  The  earthworm  has  undermined  and 
buried  rocks,  changing  greatly  the  aspect  of  the  landscape.  It  has 
preserved  ruins  and  ancient  works  of  art.  Several  Roman  villas  in 
England  owe  their  preservation  to  the  earthworm.  All  this  work  is 
accomplished  with  the  most  primitive  tools,  a tiny  proboscis,  a distensible 
pharynx,  a rather  indeterminate  tail,  a gizzard  and  the  calcareous  glands 
peculiar  to  this  lowly  creature.

An  earthworm  has  a peculiar,  crawling  movement.  Unlike  the  6nake, 
which  also  moves  without  legs,  it  has  no  scales  to  function  in  part  as  legs: 
but  it  has  a very  special  provision  for  locomotion.  On  the  under  side  of  a 
worm  are  found  numerous  setae — tiny,  bristlelike  projections.  These  will 
be  seen  to  be  in  double  rows  on  each  segment,  excepting  the  first  three  and 
the  last.  The  setae  turn  so  that  they  point  in  the  opposite  direction  from 
which  the  worm  is  moving.  It  is  this  use  of  these  clinging  bristles, 
together  with  strong  muscles,  which  enables  a worm  to  hold  tightly  to  itf 
burrow  when  bird  or  man  attempts  its  removal.  A piece  of  round  elastic 
furnishes  an  excellent  example  of  contraction  and  extension,  such  as  the 
earthworm  exhibits.  Under  the  skin  of  the  worm  are  two  sets  of  muscles ; 
the  outer  passing  in  circular  direction  around  the  body,  the  inner  running 
lengthwise.  The  movement  of  these  may  be  easily  seen  in  a good-sized, 
living  specimen.  The  body  is  lengthened  by  the  contraction  of  circular 
and  the  extension  of  longitudinal  muscles,  and  shortened  by  the  opposite 
movement. 

The  number  of  segments  may  vary  with  the  age  of  the  worm.  In  the 
immature,  the  clitellum , a thick,  whitish  ring  near  the  end,  is  absent. 
The  laying  of  the  earthworm’s  egg  is  an  interesting  performance.  A sac- 
like  ring  is  formed  about  the  body  in  the  region  of  the  clitellum.  This 
girdle  is  gradually  worked  forward  and,  as  it  is  cast  over  the  head,  the  sac- 
ends  snap  together  enclosing  the  eggs.  These  capsules,  yellowish-brown, 
football-shaped,  about  the  size  of  a grain  of  wheat,  may  be  found  in  May 
or  June  about  manure  piles  or  under  stones. 

Earthworms  are  completely  deaf,  although  sensitive  to  vibration. 
They  have  no  eyes,  but  can  distinguish  between  light  and  darkness.  The 
power  of  smell  is  feeble.  The  sense  of  taste  is  well  developed ; the  sense  of 
touch  is  very  acute;  and  we  are  not  so  sure  as  is  Dr.  Jordan,  that  the 
angleworm  is  at  ease  on  the  hook. 

Any  garden  furnishes  good  examples  of  the  home  of  the  earthworm. 
The  burrows  are  made  straight  down  at  first,  then  wind  about  irregularly. 
Usually  they  are  about  one  or  two  feet  deep,  but  may  reach  even  eight 
feet.  The  burrow  terminates  generally  in  an  enlargement  where  one  or 
several  worms  pass  the  winter.  Toward  the  surface,  the  burrow  is  lined 
with  a thin  layer  of  fine,  dark  colored  earth,  voided  by  the  worm.  This 
creature  is  an  excavator  and  builder  of  no  mean  ability.  The  towerlike 
“castings”  so  characteristic  of  the  earthworm,  are  formed  with  excreted 
earth.  Using  the  tail  as  a trowel,  it  places  earth,  now  on  one  side  and 
now  on  the  other.  In  this  work,  of  course,  the  tail  protrudes;  in  the 
search  for  food,  the  head  is  out.  A worm,  then,  must  make  its  home, 
narrow  as  it  is,  with  a view  to  being  able  to  turn  in  it. 

An  earthworm  will  bury  itself  in  loose  earth  in  two  or  three  minutes, 
and  in  compact  soil,  in  fifteen  minutes.  Pupils  should  be  able  to  make 
these  observations  easily  either  in  the  terrarium  or  in  the  garden. 

In  plugging  the  mouths  of  their  burrows,  earthworms  show  something 
that  seems  like  intelligence.  Triangular  leaves  are  invariably  drawn  in 
by  the  apex,  pine-needles  by  the  common  base,  the  manner  varying  with 
the  shape  of  the  leaf.  They  do  not  drag  in  a leaf  by  the  footstalk,  unless 
its  basal  part  is  as  narrow  as  the  apex.  The  mouth  of  the  burrow  may  be 
lined  with  leaves  for  several  inches. 

The  burrows  are  not  found  in  dry  ground  nor  in  loose  sand.  The 
earthworm  lives  in  the  finer,  moderately  wet  soils.  It  must  have  moisture 


464 


Handbook  of  N ature-Stndy 


since  it  breathes  through  the  skin,  and  it  has  sufficient  knowledge  of  soil 
texture  and  plasticity  to  recognize  the  futility  of  attempts  at  burrow 
building  with  unmanageable,  large  grains  of  sand. 

These  creatures  are  nocturnal,  rarely  appearing  by  day  unless  “drowned 
out”  of  the  burrows.  During  the  day  they  lie  near  the  surface  extended 
at  full  length,  the  head  uppermost.  Here  they  are  discovered  by  keen- 
eyed birds  and  sacrificed  by  thousands,  notwithstanding  the  strong 
muscular  protest  of  which  they  are  capable. 

Seemingly  conscious  of  its  inability  to  find  the  way  back  to  its  home, 
an  earthworm  anchors  tight  by  its  tail  while  stretching  its  elastic  length 
in  a foraging  expedition.  It  is  an  omnivorous  creature,  including  in  its 
diet  earth,  leaves,  flowers,  raw  meat,  fat,  and  even  showing  cannibalistic 
designs  on  fellow  earthworms.  In  the  schoolroom,  earthworms  may  be 
fed  on  pieces  of  lettuce  or  cabbage  leaves.  A feeding  worm  will  show  the 
proboscis,  an  extension  of  the  upper  lip  used  to  push  food  into  the  mouth. 
The  earthworm  has  no  hard  jaws  or  teeth,  yet  it  eats  through  the  hardest 
soil.  Inside  the  mouth  opening  is  a very  muscular  pharynx,  which  can  be 
extended  or  withdrawn.  Applied  to  the  surface  of  any  small  object  it 
acts  as  a suction  pump,  drawing  food  into  the  food  tube.  The  earth 
taken  in  furnishes  some  organic  matter  for  food;  calcareous  matter  is 
added  to  the  remainder  before  being  voided.  This  process  is  unique 
among  animals.  The  calcareous  matter  is  supposed  to  be  derived  from 
leaves  which  the  worms  eat.  Generally  the  earth  is  swallowed  at  some 
distance  below  the  surface,  and  finally  ejected  in  characteristic  “castings.” 
Thus,  the  soil  is  slowly  worked  over  and  kept  in  good  condition  by  earth* 
worms,  of  which  Darwin  says;  “It  may  be  doubted  whether  there  are 
many  other  animals  which  have  played  so  important  a part  in  the  history 
of  the  world  as  have  these  lowly  organized  creatures.”

“Fly  fishing  is  an  art,  a fine  art  beyond  a doubt,  but  it  is  an  art  and,  like  all  art,  it  is 
artificial.  Fishing  with  an  angleworm  is  natural.  It  fits  into  the  need  of  the  occasion. 
It  fits  in  with  the  spirit  of  the  boy.  It  is  not  by  chance  that  the  angleworm,  earthworm , 
fishworm,  is  found  in  every  damp  bank,  in  every  handy  bit  of  sod,  the  green  earth  over , 
where  there  are  races  whose  boys  are  real  boys  with  energy  enough  to  catch  a fish.  It  is 
not  by  chance  that  the  angleworm  makes  a perfect  fit  on  a hook,  with  no  anatomy  with 
which  to  feel  pains,  and  no  arms  or  legs  to  be  broken  off  or  to  be  waved  helplessly  in  the 
air.  Its  skin  is  tough  enough  so  as  not  to  tear,  not  so  tough  as  to  receive  unseemly 
bruises,  when  the  boy  is  placing  it  on  the  hook.  The  angleworm  is  perfectly  at  home  on 
the  hook.  It  is  not  quite  comfortable  anywhere  else.  It  crawls  about  on  sidewalks  after 
rain,  Reached  and  emaciated.  It  is  never  quite  at  ease  even  in  the  ground,  but  on  the 
hook  it  rests  peacefully,  with  the  apparent  feeling  that  its  natural  mission  is  performed .”

LESSON  CVII 
The  Earthworm 

Leading  thought — The  earthworm  is  a creature  of  the  soil  and  is  of  much 
economic  importance. 

Method — Any  garden  furnishes  abundant  material  for  the  study  of 
earthworms.  They  are  nocturnal  workers  and  may  be  observed  by  lan-

tern  light.  To  form  some  estimate  of  the  work  done  in  a single  night, 
remove  the  “casts”  from  a square  yard  of  earth  one  day,  and  examine 
that  piece  of  earth  the  next.  It  is  well  to  have  a terrarium  in  the  school- 
room for  frequent  observation.  Scatter  grass  or  dead  leaves  on  top  of 
the  soil,  and  note  what  happens.  For  the  study  of  the  individual  worm 
and  its  movements,  each  pupil  should  have  a worm  with  some  earth  upon 
his  desk. 

Observations — 1.  How  does  the  earthworm  crawl?  How  does  it  turn 
over?  Has  it  legs?  Compare  its  movement  with  that  of  a snake, 
another  legless  animal.  What  special  provision  for  locomotion  has  the 
earthworm  ? 

2.  Compare  the  lengths  of  the  contracted  and  extended  body.  How 
accounted  for? 

3.  Describe  the  body — its  shape  and  color,  above  and  below. 
Examine  the  segments.  Do  all  the  worms  have  the  same  number? 
Compare  the  head  end  with  the  tail  end  of  the  body.  Has  every  worm  a 
“saddle,”  or  clitellum? 

4.  Does  the  earthworm  hear  easily?  Has  it  eyes?  Is  it  sensible  to 
smell  or  to  touch?  What  sense  is  most  strongly  developed? 

5.  Describe  the  home  of  the  earthworm.  Is  it  occupied  by  more 
than  one  worm  ? How  long  does  it  take  a worm  to  make  a burrow  ? How 
does  it  protect  its  home ? How  does  it  make  a burrow?  In  what  kind  of 
soil  do  you  find  earthworms  at  work  ? 

6.  Is  the  earthworm  seen  most  often  at  night  or  by  day?  Where  is 
it  the  rest  of  the  time?  How  does  it  hold  to  its  burrow?  When  is  the 
tail  end  at  the  top  ? When  the  head  end  ? 

7.  What  is  the  food  of  the  earthworm?  How  does  it  get  its  food ? 

8.  Look  for  the  eggs  of  the  earthworm  about  manure  piles  or  under 
stones. 

9.  What  are  the  enemies  of  the  earthworm?  Is  it  a friend  or  an 
enemy  to  us?  Why?

THE  CRAYFISH 
Teacher's  Story 

HEN  I look  at  a crayfish  I envy  it,  so  rich  is  it  in 
organs  with  which  to  do  all  that  it  has  to  do. 
From  the  head  to  the  tail,  it  is  crowded  with  a 
large  assortment  of  executive  appendages.  In 
this  day  of  multiplicity  of  duties,  if  we  poor 
human  creatures  only  had  the  crayfish’s  capa- 
bilities, then  might  we  hope  to  achieve  what  lies 
before  us. 

The  most  striking  thing  in  the  appearance  of 
the  crayfish  is  the  great  pair  of  nippers  on  each  of 
the  front  legs.  Wonderfully  are  its  “thumb  and 
finger”  put  together;  the  “thumb”  is  jointed  so 
that  it  can  move  back  and  forth  freely ; and  both 
are  armed,  along  the  inside  edge,  with  saw  teeth  and  with  a sharp  claw  at 
the  tip  so  that  they  can  get  a firm  grip  upon  an  object.  Five  segments  in 
these  great  legs  can  be  easily  seen;  that  joining  the  body  is  small,  but 
each  successive  one  is  wider  and  larger,  to  the  great  forceps  at  the  end. 
The  two  stout  segments  behind  the  nippers  give  strength,  and  also  a 
suppleness  that  enables  the  claws  to  be  bent  in  any  direction. 

The  legs  of  the  pair  behind  the  big  nippers  have  five  segments  readily 
visible;  but  these  legs  are  slender  and  the  nippers  at  the  end  are  small; 
the  third  pair  of  legs  is  armed  like  the  second  pair ; but  the'  fourth  and 
fifth  pairs  lack  the  pincers,  and  end  in  a single  claw. 

But  the  tale  of  the  crayfish’s  legs  is  by  no  means  told ; for  between  and 
above  the  great  pincers  is  a pair  of  short,  small  legs  tipped  with  single 
claws,  and  fringed  on  their  inner  edges.  These  are  the  ma.xillapeds,  or 
jaw-feet;  and  behind  them,  but  too  close  to  be  seen  easily,  are  two  more 
pairs  of  jaw-feet.  As  all  of  these  jaw-feet  assist  at  meals,  the  crayfish 
apparently  always  has  a “three  fork”  dinner;  and  as  if  to  provide  accom- 
modations for  so  many  eating  utensils,  it  has  three  pairs  of  jaws  all  work- 
ing sidewise,  one  behind  the  other.  Two  of  these  pairs  are  maxillae  and 
one,  mandibles.  The  mandibles  are  the  only  ones  we  see  as  we  look  in 
between  the  jaw-feet;  they  are  notched  along  the  biting  edge.  Com 
nected  with  the  maxillae,  on  each  side,  are  two  pairs  of  threadlike  flappers,  j 
that  wave  back  and  forth  vigorously  and  have  to  do  with  setting  up  cur-  i 
rents  of  water  over  the  gills. 

Thus  we  see  that,  in  all,  the  crayfish  has  three  pairs  of  jaw-feet,  one 
pair  of  great  nippers  and  four  pairs  of  walking  feet,  two  of  which  also  have 
nippers  and  are  used  for  digging  and  carrying. 

When  we  look  upon  the  crayfish  from  above,  we  see  that  the  head  and 
thorax  are  fastened  solidly  together,  making  what  is  called  a cephalo- 
thorax.  The  cephalothorax  is  covered  with  a shell  called  the  carapace, 
which  is  the  name  given,  also  to  the  upper  part  of  the  turtle’s  shell.  The 
suture  where  the  head  joins  the  thorax  is  quite  evident.  In  looking  at 
the  head,  the  eyes  first  attract  our  attention;  each  is  black  and  oval  and 
placed  on  the  tip  of  a stalk,  so  it  can  be  extended  or  retracted  or  pushed  in 
any  direction,  to  look  for  danger.  These  eyes  are  like  the  compound  eyes 
of  insects,  in  that  they  are  made  up  of  many  small  eyes,  set  together  in  a 
honeycomb  pattern.

The  long  antennae  are  as  flexible  as  braided  whiplashes,  large  at  the 
base  and  ending  in  a threadlike  tip.  They  are  composed  of  many  seg- 
ments, the  basal  ones  being  quite  large.  Above  the  antennae  on  each  side, 
is  a pair  of  shorter  ones  called  antennules,  which  come  from  the  same 
basal  segment;  the  lower  one  is  the  more  slender  and  is  usually  directed 
forward;  the  upper  one  is  stouter,  curves  upward,  and  is  kept  always 
moving,  as  if  it  were  constantly  on  the  alert  for  impressions.  The  anten- 
nae are  used  for  exploring  far  ahead  or  behind  the  creature,  and  are  often 
thrust  down  into  the  mud  and  gravel  at  the  bottom  of  the  aquarium,  as  if 
probing  for  treasure.  The  antennules  seem  to  give  warning  of  things 
closer  at  hand.  Between  the  antennae  and  antennules  is  a pair  of  finger- 
like organs,  that  are  hinged  at  the  outer  ends  and  can  be  lifted  back,  if  we 
do  it  carefully. 

In  looking  down  upon  a crayfish,  we  can  see  six  abdominal  segments 
and  the  flaring  tail  at  the  end,  which  is  really  another  segment  greatly 
modified.  The  first  segment,  or  that  next  to  the  cephalothorax,  is  narrow; 
the  others  are  about  equal  in  size,  each  graceful  in  shape,  with  a widened 
part  at  each  side  which  extends  down  along  the  sides  of  the  creature. 
These  segments  are  well  hinged  together  so  that  the  abdomen  may  be 
completely  curled  beneath  the  cephalothorax.  The  plates  along  the  sides 
are  edged  with  fringe.  The  tail  consists  of  five  parts,  one  semicircular  in 
the  center,  and  two  fan-shaped  pieces  at  each  side,  and  all  are  margined 
with  fringe.  This  tail  is  a remarkable  organ.  It  can  be  closed  or  extended 
sidewise  like  a fan ; it  can  be  lifted  up  or  curled  beneath. 

Looking  at  the  crayfish  from  below,  we  see  on  the  abdomen  some  very 
beautiful  featherlike  organs  called  swimmerets.  Each  swimmeret  con- 
sists of  a basal  segment  with  twin  paddles  joined  to  its  tip,  each  paddle 
being  narrow  and  long  and  fringed  with  hairs.  The  mother  crayfish  has 
four  pairs  of  these,  one  pair  on  each  of  the  second,  third,  fourth  and  fifth 
segments;  her  mate  has  an  additional  larger  pair  on  the  first  segment. 
These  swimmerets,  when  at  rest,  lie  close  to  the  abdomen  and  are  directed 
forward  and  slightly  inward.  When  in  motion,  they  paddle  with  a back- 
ward, rhythmic  motion,  the  first  pair  setting  the  stroke  and  the  other  pairs 
following  in  succession.  This  motion  sends  the  body  forward,  and  the 
swimmerets  are  chiefly  used  to  aid  the  legs  in  forward  locomotion.  A 
crayfish,  on  the  bottom  of  a pond,  seems  to  glide  about  with  great  ease; 
but  place  it  on  land,  and  it  is  an  awkward  walker.  The  reason  for  this 
difference  lies,  I believe,  in  the  aid  given  by  the  swimmerets  when  the 
creature  is  in  water.  Latter  says:  “In  walking,  the  first  three  pairs  of 

legs  pull  and  the  fourth  pair  pushes.  Their  order  of  movement  is  as  fol- 
lows: The  first  on  the  right  and  the  third  on  the  left  side  move  together, 

next  the  third  right  and  the  first  left,  then  the  second  right  and  fourth 
left,  and  lastly  the  fourth  right  and  second  left.” 

When  the  crayfish  really  wishes  to  swim,  the  tail  is  suddenly  brought 
into  use;  it  is  thrust  out  backward,  lays  hold  of  the  water  by  spreading 
out  widely,  and  then  doubles  under  with  a spasmodic,  jerk  which  pulls  the 
creature  swiftly  backward. 

The  crayfish’s  appearance  is  magically  transformed  when  it  begins  to 
swim;  it  is  no  longer  a creature  of  sprawling  awkward  legs  and  great 
clumsy  nippers;  now,  its  many  legs  lie  side  by  side  supinely  and  the  great 
claws  are  limp  and  flow  along  in  graceful  lines  after  the  body,  all  obedient 
to  the  force  which  sends  the  creature  flying  through  the  water.  I cannot 
discover  that  the  swimmerets  Infip  in  this  movement.

A crayfish. 

Drawn  by  Anna  C.  Stryke. 


The  mother  crayfish  has  another  use  for  her  swimmerets ; in  the  spring, 
when  she  is  ready  to  lay  eggs,  she  cleans  off  her  paddles  with  her  hind  legs, 
covers  them  with  waterproof  glue,  and  then  plasters  her  eggs  on  them  in 
grapelike  clusters  of  little  dark  globules.  What  a nice  way  to  look  after 
her  family!  The  little  ones  hatch,  but  remain  clinging  to  the  maternal 
swimmerets,  until  they  are  large  enough  to  scuttle  around  on  the  brook 
bottom  and  look  out  for  themselves. 

The  breathing  apparatus  of  the  crayfish  cannot  be  seen  without  dissec- 
tion. All  the  walking  legs,  except  the  last  pair,  have  gills  attached  to 
that  portion  of  them  which  joins  the  body,  and  which  lies  hidden  under- 
neath the  sides  of  the  carapace  or  shell.  The  blood  is  forced  into  these 
gills,  sends  off  its  impurities  through  their  thin  walls  and  takes  in  the 
oxygen  from  the  water,  currents  of  which  are  kept  steadily  flowing  for- 
ward. 

Crayfishes  haunt  still  pools  along  brooksides  and  river  margins  and 
the  shallow  ponds  of  our  fresh  waters.  There  they  hide  beneath  sticks 
and  stones,  or  in  caves  of  their  own  making,  the  doors  of  which  they  guard 
with  the  big  and  threatening  nippers,  which  stand  ready  to  grapple  with 
anybody  that  comes  to  inquire  if  the  folks  are  at  home.  The  upper  sur- 
face of  the  crayfish’s  body  is  always  so  nearly  the  color  of  the  brook  bot- 
tom, that  the  eye  seldom  detects  the  creature  until  it  moves;  and  if  some 
enemy  surprises  one,  it  swims  off  with  terrific  jerks  which  roil  all  the 
water  around  and  thus  covers  its  retreat.  In  the  winter,  our  brook  forms 
hibernate  in  the  muddy  bottoms  of  their  summer  haunts.  There,  are 
many  species  ; some  in  our  Southern  States,  when  the  dry  season  comes  on, 
live  in  little  wells  which  they  dig  deep  enough  to  reach  water.  They  heap

tip  the  soil  which  they  excavate  around  the  mouth  of  the  well,  making 
well-curbs  of  mud ; these  are  ordinarily  called  “crawfish  chimnies.”  The 
crayfishes  fiffH’their  food  in  the  flotsam  and  jetsam  of  the  pool.  They 
seem  fond  of  the  flesh  of  dead  fishes  and  are  often  trapped  by  its  use  as 
bait. 

The  growth  of  the  crayfish  is  like  that  of  insects ; as  its  outer  covering 
is  a hard  skeleton  that  will  not  stretch,  it  is  shed  as  often  as  necessary;  it 
breaks  open  down  the  middle  of  the  back  of  the  carapace,  and  the  soft, 
bodied  creature  pulls  itself  out,  even  to  the  last  one  of  its  claws.  While  its 
new  skin  is  yet  elastic,  it  stretches  to  its  utmost;  but  this  skin  also 
hardens  after  a time  and  is,  in  its  turn, "she'd.  Woe  to  the  crayfish  caught 
in  this  helpless,  soft  condition  after  molting!  For  it  then  has  no  way  to 
protect  itself.  We  sometimes  find  the  old  skin  floating,  perfect  in  every 
detail,  and  so  transparent  that  it  seems  the  ghost  of  a crayfish. 

Not  only  is  the  crayfish  armed  in  the  beginning  with  a great  number  of 
legs,  antennae,  etc.,  but  if  it  happens  to  lose  any  of  these  organs,  they  will 
grow  again.  It  is  said  that,  when  attacked,  it  can  voluntarily  throw  off 
one  or  more  of  its  legs.  Wediave  often  found  one  of  these  creatures  with 
one  of  the  front  claws  much  larger  than  the  other;  it  had  probably  lost 
its  big  claw  in  a fight,  and  the  new  growth  was  not  yet  completed. 

I have  been  greatly  entertained  by  watching  a female  crayfish  make 
her  nest  in  my  aquarium  which  has,  for  her  comfort,  a bottom  of  three 
inches  of  clean  gravel.  She  always  commences  at  one  side  by  thrusting 
down  her  antennae  and  nippers  between  the  glass  and  stones ; she  seizes  a 
pebble  in  each  claw  and  pulls  it  up  and  in  this  way  starts  her  excavation; 
but  when  she  gets  ready  to  carry  off  her  load,  she  comes  to  the  task  with 
her  tail  tucked  under  her  body,  as  a lady  tucks  up  her  skirts  when  she  has 
something  to  do  that  requires  freedom  of  movement.  Then  with  her 
great  nippers  and  the  two  pairs  of  walking  feet,  also  armed  with  nippers, 
she  loads  up  as  much  as  she  can  carry  between  her  great  claws  and  her 
breast.  She  keeps  her  load  from  overflowing  by  holding  it  down  with  her 
first  pair  of  jaw-feet,  just  as  I have  seen  a schoolboy  use  his  chin,  when 
carrying  a too  large  load  of  books ; and  she  keeps  the  load  from  falling  out 
by  supporting  it  from  beneath  with  her  first  pair  of  walking  legs.  Thus, 
she  starts  off  with  her  “apron”  full,  walking  on  three  pairs  of  feet,  until 
she  gets  to  the  dumping  place;  then  she  suddenly  lets  go  and  at  the  same 
time  her  tail  straightens  out  with  a gesture  which  says  plainly,  “There!” 
Sometimes  when  she  gets  a very  large  load,  she  uses  her  second  pair  of 
walking  legs  to  hold  up  the  burden,  and  crawls  off  successfully,  if  not  with 
ease,  on  two  pairs  of  legs, — a most  unnatural  quadruped. 

I had  two  crayfishes  in  a cage  in  an  aquarium,  and  each  made  a nest  in 
the  gravel  at  opposite  ends  of  the  cage,  heaping  up  the  debris  into  a parti- 
tion between  them.  I gave  one  an  earthworm,  which  she  promptly 
seized  with  her  nippers;  she  then  took  up  a good  sized  pebble  in  the  nip- 
pers of  her  front  pair  of  walking  legs,  glided  over  to  the  other  nest,  spite- 
fully threw  down  both  worm  and  pebble  on  top  of  her  fellow  prisoner,  and 
then  sped  homeward.  Her  victim  responded  to  the  act  by  rising  up  and 
expressing  perfectly,  in  his  attitude  and  the  gestures  of  his  great  claws, 
the  most  eloquent  of  crayfish  profanity.  In  watching  crayfishes  carry 
pebbles,  I have  been  astonished  to  see  how  constantly  the  larger  pair  of 
jaw-feet  are  used  to  help  pick  up  and  carry  the  loads.

LESSON  CVIII 
The  Crayfish 

Leading  thought — The  crayfish,  or  crawfish,  as  it  is  sometimes  called, 
has  one  pair  of  legs  developed  into  great  pincers  for  seizing  and  tearing  its 
food  and  for  defending  itself  from  enemies.  It  can  live  in  mud  or  water. 
It  belongs  to  the  same  animal  group  as  do  the  insects,  and  it  is  a near 
cousin  of  the  lobster. 

Method — Place  a crayfish  in  an  aquarium  (a  battery  jar  or  a two-quart 
Mason  jar)  in  the  schoolroom,  keeping  it  in  clear  water  until  the  pupils 
have  studied  its  form.  It  will  rise  to  explore  the  sides  of  the  aquarium  at 
first,  and  thus  show  its  mouth  parts,  legs  and  swimmerets.  Afterwards, 
place  gravel  and  stone  in. the  bottom  of  the  aquarium,  so  that  it  can  hide 
itself  in  a little  cavity  which  it  will  make  by  carrying  pebbles  from  one 
side.  Wash  the  gravel  well  before  it  is  put  in,  so  that  the  water  will  be 
unclouded  and  the  children  can  watch  the  process  of  excavation. 

Observations — i.  What  is  there  peculiar  about  the  crayfish  which 
makes  it  difficult  to  pick  it  up?  Examine  one  of  these  great  front  legs 
carefully  and  see  how  wonderfully  it  is  made.  How  many  parts  are  there 
to  it?  Note  how  each  succeeding  part  is  larger  from  the  body  to  the  claws. 
Note  the  tips  which  form  the  nippers  or  chelae,  as  they  are  called.  How 
are  they  armed  ? How  are  the  gripping  edges  formed  to  take  hold  of  an 
object?  How  wide  can  the  nippers  be  opened,  and  how  is  this  done? 
Note  the  two  segments  behind  the  great  claw  and  describe  how  they  help 
the  work  of  the  nippers. 

2.  Study  the  pair  of  legs  behind  the  great  claws  or  chelae,  and  com- 
pare the  two  pairs,  segment  by  segment.  How  do  they  differ  except  as  to- 
size?  How  do  the  nippers  at  the  end  compare  with  the  big  ones?  Look 
at  the  next  pair  of  legs  behind  these ; are  they  similar?  How  do  the  two 
pairs  of  hind  legs  differ  in  shape  from  the  two  pairs  in  front  of  them? 

3 . Look  between  the  great  front  claws  and  see  if  you  can  find  another 
pair  of  small  legs.  Can  you  see  anything  more  behind  or  above  these  little 
legs? 

4.  When  the  crayfish  lifts  itself  up  against  the  side  of  the  jar,  study 
its  mouth.  Can  you  see  a pair  of  notched  jaws  that  work  sidewise? 
Can  you  see  two  or  three  pairs  of  threadlike  organs  that  wave  back  and 
forth  in  and  out  the  mouth? 

5.  How  many  legs,  in  all,  has  the  crayfish?  What  are  the  short  legs 
near  the  mouth  used  for?  What  are  the  great  nippers  used  for?  How 
many  legs  does  the  crayfish  use  when  walking?  In  what  order  are  they 
moved?  Is  the  hind  pair  used  for  pushing?  What  use  does  it  make  of 
the  pincers  on  the  first  and  second  pairs  of  walking  legs? 

6.  Look  at  the  crayfish  from  above ; the  head  and  the  covering  of  the 
thorax  are  soldered  together  into  one  piece.  When  this  occurs,  the  whole 
is  called  a cephalothorax ; and  the  cover  is  called  by  the  same  name  as  the 
upper  shell  of  the  turtle,  the  carapace.  Can  you  see.  where  the  head  is 
joined  to  the  thorax? 

‘7.  Look  carefully  at  the  eyes.  Describe  how  they  are  set.  Can  they 
be  pushed  out  or  pulled  in?  Can  they  be  moved  in  all  directions?  Of 
what  advantage  is  this  to  the  crayfish? 

8 . How  many  antennae  has  the  crayfish  ? Describe  the  long  ones  and 
tell  how  they  are  used . Do  the  two  short  ones  on  each  side  come  from  the 
same  basal  segment?  These  little  ones  are  called  the  antennules. 


Other  Invertebrate- Animal  Study 


47i 


Describe  the  antennules  of  each  side  and  tell  how  they  differ.  Can  you 
see  the  little  fingerlike  organs  which  clasp  above  the  antennae  and  below 
the  antennules  on  each  side  of  the  head?  Can  these  be  moved? 

9.  Look  at  the  crayfish  from  above.  How  many  segments  are  there 
in  the  abdomen?  Note  how  graceful  the  shape  of  each  segment.  Note 
that  each  has  a fan-shaped  piece  down  the  side.  Describe  how  the  edges 
of  the  segments  along  the  sides  are  margined. 

10.  Of  how  many  pieces  is  the  tail  made?  Make  a sketch  of  it. 
How  are  the  pieces  bordered?  Can  the  pieces  shut  and  spread  out  side- 
wise?  Is  the  tail  hinged  so  it  can  be  lifted  up  against  the  back  or  curled 
under  the  body  ? 

11.  Look  underneath  the  abdomen  and  describe  the  little  fringed 
organs  called  the  swimmerets.  How  many  are  there? 

12.  How  does  the  crayfish  swim?  With  what  does  it  make  the 
stroke  ? Describe  carefully  this  action  of  the  tail.  When  it  is  swimming, 
does  it  use  its  swimmerets?  Why  do  not  the  many  legs  and  big  nippers 
obstruct  the  progress  of  the  crayfish,  when  it  is  swimming? 

13.  When  does  the  crayfish  use  its  swimmerets?  Do  they  work  so  as 
to  push  the  body  backward  or  forward?  Do  you  know  to  what. use  the 
mother  crayfish  puts  her  swimmerets? 

14.  Do  you  know  how  crayfishes  breathe?  Do  you  know  what  they 
eat  and  where  they  find  it? 

15.  Where  do  you  find  crayfishes?  Where  do  they  like  to  hide?  Do 
they  go  headfirst  into  their  hiding  place,  or  do  they  back  in?  Do  they 
stand  ready  to  defend  their  retreat?  When  you  look  down  into  the 
brook,  are  the  crayfishes  usualty  seen  until  they  move?  Why  is  this? 
Where  do  the  crayfishes  pass  the  winter?  Did  you  ever  see  the  crayfish 
burrows  or  mud  chimnies? 

16.  If  the  crayfish  loses  one  of  its  legs  or  antennas,  does  it  grow  out 
again?  How  does  the  crayfish  grow? 

17.  Put  a crayfish  in  an  aquarium  which  has  three  inches  of  coarse 

gravel  on  the  bottom,  and  watch  it  make  its  den.  How  does  it  loosen  up 
a stone?  With  how  many  legs  does  it  carry  its  burden  of  pebbles  when 
digging  its  cave?  How  does  it  use  its  jaw-feet,  its  nippers,  and  its  first 
and  second  pairs  of  walking  legs  in  this  work?  1 


“ A rock-lined , wood-embosomed  nook, 

Dim  cloister  of  the  chanting  brook! 

A chamber  within  the  channelled  hills, 

Where  the  cold  crystal  brims  and  spills, 

By  dark-browed  caverns  blackly  flows, 

Falls  from  the  cleft  like  crumbling  snows, 

And  purls  and  splashes,  breathing  round 
A soft,  suffusing  mist  of  sound”

DADDY-LONGLEGS,  OR  GRANDFATHER  GREYBEARD 
Teacher's  Story 

WONDER  if  there  ever  was  a country  child  who  has 
not  grasped  firmly  the  leg  of  one  of  these  little 
sprawling  creatures  and  demanded:  “Grandfather 

Greybeard,  tell  me  where  the  cows  are  or  I’ll  kill 
you,”  and  Grandfather  Greybeard,  striving  to  get 
away,  puts  out  one  of  his  long  legs  this  way,  and 
another  that  way,  and  points  in  so  many  directions 
that  he  usually  saves  his  life,  since  the  cows  must  be 
somewhere.  It  would  be  more  interesting  to  the 
children  and  less  embarrassing  to  the  “daddy”  if  they  were  taught  to  look 
more  closely  at  those  slender,  hairlike  legs. 

“Daddy’s”  long  legs  are  seven  jointed.  The  first  segment  is  seemingly 
soldered  fast  to  the  lower  side  of  his  body,  and  is  called  the  coxa.  The 
next  segment  is  a mere  knob,  usually  black  and  ornamental,  and  is  called 
the  trochanter.  Then  comes  the  femur,  a rather  long  segment  directed 
upward;  next  is  a short  swollen  segment — the  “knee  joint”  or  patella; 
next  the  tibia,  which  is  also  rather  long.  Then  comes  the  metatarsus  and 
tarsus,  which  seemingly  make  one  long  downward-directed  segment,  out- 
curving  at  the  tips,  on  which  the  “daddy”  tip-toes  along. 

I have  seen  a “daddy”  walk  into  a drop  of  water  and  his  foot  was  never 
wetted,  so  light  was  his  touch  on  the  water  surface  film.  The  second  pair 
of  legs  is  the  longest ; the  fourth  pair  next,  and  the  first  pair  usually  the 
shortest.  The  legs  of  the  second  pair  are  ordinarily  used  in  exploring  the 
surroundings.  Notice  that,  when  the  “daddy”  is  running,  these  two  legs 
are  spread  wide  apart  and  keep  in  rapid  motion ; their  tips,  far  more  sensi- 
tive than  any  nerves  of  our  own,  tell  him  the  nature  of  his  surroundings, 
by  a touch  so  light  that  we  cannot  feel  it  on  the  hand.  We  have  more 
respect  for  one  of  these  hairlike  legs,  when  we  know  it  is  capable  of  trans- 
mitting intelligence  from  its  tip. 

The  “daddy”  is  a good  traveler  and  moves  with  remarkable  rapidity. 
And  why  not?  If  our  legs  were  as  long  in  comparison  as  his,  they  would 
be  about  forty  feet  in  length.  When 
the  “daddy”  is  running,  the  body  is 
always  held  a little  distance  above  the 
ground;  but  when  the  second  pair 
of  legs  suggests  to  him  that  there 
may  be  something  good  to  eat  in  the 
neighborhood,  he  commences  a pecul- 
iar teetering  motion  of  the  body, 
apparently  touching  it  to  the  ground 
at  every  step ; as  the  body  is  carried 
tilted  with  the  head  down,  this  move- 
ment enables  the  creature  to  explore 
the  surface  below  him  with  his  palpi,  which  he  ordinarily  carries  bent  be* 
neath  his  face,  with  the  ends  curled  up  under  his  “chin.”  The  palpi  have 
four  segments  that  are  easily  seen,  and  although  they  are  ordinarily 
carried  bent  up  beneath  the  head,  they  can  be  extended  out  quite  a dis- 
tance if  “daddy”  wishes  to  test  a substance.  The  end  segment  of  the 
palpus  is  tipped  with  a single  claw 


One  oj  “ daddy's ” long  legs  with 
segments  named. 


Other  Invertebrate- Animal  Study 


473 


Beneath  the  palpi  is  a pair  of  jaws;  these,  in  some  species,  extend 
beyond  the  palpi.  I have  seen  a daddy-longlegs  hold  food  to  his  jaws 
with  his  palpi  and  he  seemed  also  to  use  them  for  stuffing  it  into  his 

The  body  of  the  daddy-longlegs  is  a little  oblong  object,  looking  more 
like  a big  grain  of  wheat  than  anything  else,  because  in  these  creatures  the 
head,  thorax  and  abdomen  are  all  grown  together  compactly.  On  top  ot 
the  body,  between  the  feeler-legs,  is  a little  black  dot,  and  to  the  nakec 
eye  it  would  seem  that  if  this  were  an  organ  of  sight  the  creature  must  be  a 
Cyclops  with  only  one  eye.  But  under  the  lens  this  is  seen  to  be  a raised 
knob  and  there  is  on  each  side  of  it,  a little  shining  black  eye.  We  hardly 
see  the  use  of  two  eyes  set  so  closely  together,  but  probably  the  daddy 
does. 


The  most  entertaining  thing  which  a “daddy”  in  captivity  is  likely  to 
do,  is  to  clean  his  legs;  he  is  very  particular  about  his  legs,  and  he  will 
grasp  one  close  to  the  basal  joint  in  his  jaws  and  slowly  pull  it  through, 
meanwhile  holding  the  leg  up  to  the  jaws  with  the  palpi,  while  he  indus- 
triously nibbles  it  clean  for  the  whole  length  to  the  very  toe.  Owing  to 
the  likelihood  of  his  losing  one  of  his  legs,  he  has  the  power  of  growing  a 
new  one;  so  we  often  see  a “daddy”  with  one  or  more  legs  only  half 
grown. 

There  are  many  species  of  daddy-longlegs  in  the  United  States,  and 
some  of  them  do  not  have  the  characteristic  long  legs.  In  the  North,  all 
except  one  species  die  at  the  approach  of  winter;  but  not  until  after  the 
female,  which,  by  the  way,  ought  to  be  called  “granny-longlegs,”  has  laid 
her  eggs  in  the  ground,  or  under  some  protecting  stone,  or  in  some  safe 
crevice  of  wood  or  bark.  In  the  spring  the  eggs  hatch  into  tiny  little 
creatures  which  look  just  like  the  old  daddy-longlegs,  except  for  their  size. 
They  get  their  growth  like  insects,  by  shedding  their  skins  as  fast  as  they 
outgrow  them.  It  is  interesting  to  study  one  of  these  cast  skins  with  a 
lens.  There  it  stands  with  a slit  down  its  back,  and  with  the  skin  of  each 
leg  absolutely  perfect  to  the  tiny  claw!  Again  we  marvel  at  these  legs 
that  seem  so  threadlike,  and  which  have  an  outer  covering  that  can  be 
shed.  Some  say  that  the  daddy-longlegs  live  on  small  insects  which  they 
straddle  over  and  pounce  down  upon,  and  some  say  they  feed  upon  decay- 
ing matter  and  vegetable  juices.  This  would  be  an  interesting  line  o£ 
investigation  for  pupils,  since  they  might  be  able  to  give  many  new  facts 
ibout  the  food  of  these  creatures.  The  “daddies”  are  night  prowlers, 
and  like  to  hide  in  crevices  by  day,  waiting  for  the  dark  to  hunt  for  their 
food.  They  have  several  common  names.  Besides  the  two  given  they 


474 


Handbook  of  Nature-Study 


are  called  “harvestmen”  and  the  French  call  them  “haymakers.”  Both 
of  these  names  were  very  probably  given,  because  the  creatures  appear  in 
greater  numbers  at  the  time  of  haying  and  harvesting. 

LESSON  CIX 
The  Daddy-Longlegs 

Leading  thought — These  long-legged  creatures  have  one  pair  of  legs 
too  many  to  allow  them  to  be  classed  with  the  insects.  They  are  more 
nearly  related  to  the  spiders,  who  also  have  eight  legs.  They  are  pretty 
creatures  when  examined  closely,  and  they  do  many  interesting  things. 

Method — Put  a grandfather  greybeard  in  a breeding  cage  or  under  a 
large  tumbler,  and  let  the  pupils  observe  him  at  leisure.  If  you  place  a few 
drops  of  sweetened  water  at  one  side  of  the  cage,  the  children  will  surely 
have  an  opportunity  to  see  this  amusing  creature  clean  his  legs. 

Observations — i.  Where  did  you  find  the  harvestman?  What  did 
it  do  as  soon  as  it  was  disturbed  ? How  many  names  do  you  know  for  this 
little  creature  ? 

2.  A “daddy”  with  such  long  legs  certainly  ought  to  have  them 
studied.  How  many  segments  in  each  leg?  How  do  the  segments  look? 
How  do  the  legs  look  where  they  are  fastened  to  the  body?  Which  is  the 
longest  pair  of  legs?  The  next?  The  next?  The  shortest? 

3 . If  you  had  such  long  stilts  as  he  has,  they  would  be  about  forty  feet 
long.  Would  you  lift  yourself  that  high  in  the  air?  Does  the  “daddy” 
lift  his  body  high  or  swing  it  near  the  ground?  What  shape  is  the  body? 
Can  you  see  if  there  is  a distinct  head  ? Can  you  see  a black  dot  on  top  of 
the  front  end  of  the  body?  If  you  should  see  this  dot  through  a micro- 
scope it  would  prove  to  be  two  bright  black  eyes.  Why  should  the 
daddy’s  eyes  be  on  top  ? 

4.  Do  you  see  a pair  of  organs  that  look  like  feelers  at  the  front  end  of 
the  body?  These  are  called  palpi.  How  does  he  use  his  palpi?  Give 
him  a little  bruised  or  decaying  fruit,  and  see  him  eat.  Where  do  you 
think  his  mouth  is?  Where  does  he  keep  his  palpi  when  he  is  not  using 
them  for  eating? 

5.  Note  what  care  he  takes  of  his  legs.  How  does  he  clean  them? 
Which  does  he  clean  the  oftenest?  Do  you  think  the  very  long  second 
pair  of  legs  is  used  as  much  for  feeling  as  for  walking?  Put  some  object 
in  front  of  the  “daddy”  and  see  him  explore  it  with  his  legs.  How  much 
of  the  leg  is  used  as  a foot  when  the  “daddy”  stands  or  runs? 

6.  When  running  fast,  how  does  the  “daddy”  carry  his  body?  When 
exploring  how  does  he  carry  it?  Do  you  ever  find  the  “daddy”  with  his 
body  resting  on  the  surface  on  which  he  is  standing?  When  resting,  are 
all  eight  of  his  legs  on  the  ground?  Which  are  in  the  air?  Is  the  head 
end  usually  tilted  up  or  down? 

7.  Do  you  see  the  daddy-longlegs  early  in  the  spring?  When  do  you 
find  him  most  often?  How  do  you  suppose  he  passes  the  winter  in  our 
climate?  Have  you  ever  seen  a “daddy”  with  one  leg  much  shorter  than 
the  other?  How  could  you  explain  this? 

8.  Try  and  discover  what  the  daddy-longlegs  eats,  and  where  he  finds 
his  food?

SPIDERS 
Teacher's  Story 

HE  spiders  are  the  civil  engineers  among  the  small 
inhabitants  of  our  fields  and  woods.  They  build 
strong  suspension  bridges,  from  which  they  hang 
nets  made  with  exquisite  precision;  and  they 
build  aeroplanes  and  balloons,  which  are  more 
efficient  than  any  that  we  have  yet  constructed ; 
for  although  they  are  not  exactly  dirigible,  yet 
they  carry  the  little  balloonists  where  they  wish 
to  go,  and  there  are  few  fatal  accidents.  More- 
over, the  spiders  are  of  much  economic  impor- 
tance,  since  they  destroy  countless  millions  of 
insects  every  year,  most  of  which  are  noxious — 
like  flies,  mosquitoes,  bugs  and  grasshoppers. 

There  is  an  impression  abroad  that  all  spiders  are  dangerous  to  handle. 
Thi;  is  a mistake;  the  bite  of  any  of  our  common  spiders  is  not  nearly 
so  dangerous  as  the  bite  of  a malaria-laden  mosquito.  Although  there  is 
a little  venom  injected  into  the  wound  by  the  bite  of  any  spider,  yet  there 
is  no  species  found  in  the  Northern  States  whose  bite  is  sufficiently 
venomous  to  be  feared. 

There  is  no  need  for  studying  the  anatomy  of  the  spider  closely  in 
nature-study.  Our  interest  lies  much  more  in  the  wonderful  structures 
made  by  the  spiders,  than  in  a detailed  study  of  the  little  creatures  them- 
selves. 

Cobwebs 

“Here  shy  Arachne  winds  her  endless  thread, 

And  weaves  her  silken  tapestry  unseen, 

Veiling  the  rough-hewn  timbers  overhead. 

And  looping  gossamer  festoons  between.” 

— Elizabeth  Akers. 

Our  house  spiders  are  indefatigable  curtain-weavers.  We  never  sus- 
pect their  presence,  until  suddenly  their  curtains  appear  before  our  eyes, 
in  the  angles  of  the  ceilings — invisible  until  laden  with  dust.  The  cob- 
webs are  made  of  crisscrossed  lines,  which  are  so  placed  as  to  entangle  any 
fly  that  comes  near.  The  lines  are  stayed  to  the  sides  of  the  wall  and  to 
each  other  quite  firmly,  and  thus  they  are  able  to  hold  a fly  that  touches 
them.  The  spider  is  likely  to  be  in  its  little  den  at  the  side  of  the  web; 
this  den  may  be  in  a crevice  in  the  corner  or  in  a tunnel  made  of  the  silk. 
As  soon  as  a fly  becomes  entangled  in  the  web  the  spider  runs  to  it,  seizes 
it  in  its  jaws,  sucks  its  blood,  and  then  throws  away  the  shell,  the  wings 
and  legs.  If  a spider  is  frightened,  it  at  first  tries  to  hide  and  then  may 
drop  by  a thread  to  the  floor.  If  we  catch  the  little  acrobat  it  will  usually 
“play  possum”  and  we  may  examine  it  more  closely  through  a lens.  We 
shall  find  it  is  quite  different  in  form  from  an  insect.  First  to  be  noted,  it 
has  eight  legs ; but  most  important  of  all,  it  has  only  two  parts  to  the  body. 
The  head  and  thorax  are  consolidated  into  one  piece,  which  is  called  the 
cephalothorax.  The  abdomen  has  no  segments  like  that  of  the  insects, 
and  is  joined  to  the  cephalothorax  by  a short,  narrow  stalk.  At  the  front

of  the  head  is  the  mouth,  guarded  by  two  mandibles,  each  ending  in  a 
sharp  claw,  at  the  tip  of  which  the  poison  gland  opens.  It  is  by  thrusting 
these  mandibles  into  its  prey  that  it  kills  its  victims.  On  each  side  of  the 
mandible  is  a palpus,  which  in  the  males  is  of  very  strange  shape.  The 
eyes  are  situated  on  the  top  of  the  head.  There  are  usually  four  pairs  of 
these  eyes,  and  each  looks  as  beady  and  alert  as  if  it  were  the  only  one. 

The  spinning  organs  of  the  spider  are  situated  near  the  tip  of  the 
abdomen,  while  the  spinning  organ  of  the  caterpillar  is  situated  near  its 
lower  lip.  The  spider’s  silk  comes  from  two  or  three  pairs  of  spinnerets 
which  are  fingerlike  in  form,  and  upon  the  end  of  each  are  many  small 
tubes  from  which  the  silk  is  spun.  The  silk  is  in  a fluid  state  as  it  issues 
from  the  spinnerets,  but  it  hardens  immediately  on  contact  with  the  air. 
In  making  their  webs,  spiders  produce  two  kinds  of  silk,  one  is  dry  and 
inelastic,  making  the  framework  of  the  web ; the  other  is  sticky  and  elas- 
tic, clinging  to  anything  that  it  touches.  The  body  and  the  legs  of 
spiders  are  usually  hairy. 

LESSON  CX 
Cobwebs 

Leading  thought — The  cobwebs  which  are  found  in  the  corners  of  ceil- 
ings and  in  other  dark  places  in  our  houses,  are  made  by  the  house  spider 
which  spins  its  web  in  these  situations  for  the  purpose  of  catching  insects. 

Method — The  pupils  should  have  under  observation  a cobweb  in  a 
corner  of  a room,  preferably  with  a spider  in  it. 

Observations — i.  Is  the  web  in  a sheet  or  is  it  a mass  of  crisscrossed, 
tangled  threads?  How  are  the  threads  held  in  place? 

2.  What  is  the  purpose  of  this  web?  Where  does  the  spider  hide? 
Describe  its  den. 

3.  If  a fly  becomes  tangled  in  a web,  describe  the  action  of  the  spider. 
Does  the  spider  eat  all  of  the  fly?  What  does  it  do  with  the  remains? 

4.  If  the  spider  is  frightened,  what  does  it  do?  Where  does  the 
silken  thread  come  from,  and  how  does  its  source  differ  from  the  source  of 
the  silken  thread  spun  by  caterpillars? 

5.  Imprison  a spider  under  a tumbler  or  in  a vial,  and  look  at  it  very 
carefully.  How  many  legs  has  it?  How  does  the  spider  differ  from 
insects  in  this  respect  ? How  many  sections  are  there  to  the  body  ? How 
does  the  spider  differ  from  insects  in  this  respect? 

6.  Look  closely  at  the  head.  Can  you  see  the  hooked  jaws,  or  fangs? 
Can  you  see  the  palpi  on  each  side  of  the  jaws?  Where  are  the  spider’s 
eyes?  How  many  pairs  has  it? 


When  the  tangled  cobweb  pulls 
The  cornflower' s cap  awry , 

And  the  lilies  tall  lean  over  the  wall 
To  bow  to  the  butterfly,, 

It  is  July.

THE  FUNNEL  WEB 
Teacher's  Story 

“ And  dew-bright  webs  festoon  the  grass 
In  roadside  fields  at  morning.” 

— Elizabeth  Akers. 

Sometimes  on  a dewy  morning,  a field  will  seem  carpeted  with  these 
webs,  each  with  its  opening  stretched  wide,  and  each  with  its  narrow 
hallway  of  retreat.  The  general  shape  of  the  web  is  like  that  of  a broad 
funnel  with  a tube  leading  down  at  one  side.  This  tube  is  used  as  a 
hiding  place  for  the  spider,  which  thus  escapes  the  eyes  of  its  enemies,  and 
also  keeps  out  of  sight  of  any  insects  that  might  be  frightened  at  seeing  it, 
and  so  avoid  the  web.  But  the  tube  is  no  cul-de-sac;  quite  to  the  con- 
trary, it  has  a rear  exit,  through  which  the  spider,  if  frightened,  escapes 
from  attack. 

The  web  is  formed  of  many  lines  of  silk  crossing  each  other  irregularly, 
forming  a firm  sheet.  This  sheet  is  held  in  place  by  many  guy-lines, 
which  fasten  it  to  surrounding  objects.  If  the.  web  is  touched  lightly,  the 
spider  rushes  forth  from  its  lair  to  seize  its  prey;  but  if  the  web  be  jarred 
roughly,  the  spider  speeds  out  through  its  back  door  and  can  be  found 
only  with  difficulty.  The  smaller  insects  of  the  field,  such  as  flies  and 
bugs,  are  the  chief  food  of  this  spider;  it  rarely  attempts  to  seize  a grown 
grasshopper. 


47s 


Handbook  of  N atur e-Study 


The  funnel-shaped  webs  in  dark  corners  of.  cellars  are  made  by  a 
species  which  is  closely  related  to  the  grass  spider  and  has  the  same  general 
habits,  but  which  builds  in  these  locations  instead  of  in  the  grass. 

LESSON  CXI 
The  Funnel  Web 

Leading  thought — The  grass  spider  spins  funnel-shaped  webs  in  the 
grass  to  entrap  the  insects  of  the  field.  This  web  has  a back  door. 

Method — Ask  the  pupils  to  observe  a web  on  the.  grass  with  a spider 
within  it. 

Observations — i.  What  is  the  general  shape  of  the  web?  Is  there  a 
tunnel  leading  down  from  it?  Why  is  it  called  a funnel  web? 

2 Of  what  use  is  the  funnel  tube,  and  what  is  its  shape  ? Where  does 
it  lead,  and  of  what  use  is  it  to  the  spider?  Can  you  corner  a spider  in  its 
funnel  tube  ? Why  not  ? 

3.  How  is  the  web  made?  Is  there  any  regularity  in  the  position  of 
the  threads  that  make  it?  How  is  it  stayed  in  place? 

4.  Touch  the  web  lightly,  and  note  how  the  spider  acts?  Jar  the 
web  roughly,  and  what  does  the  spider  do? 

5.  What  insects  become  entangled  in  this  web? 

6.  Compare  this  web  with  similar  funnel  webs  found  in  corners  of 
cellars,  sheds  or  piazzas,  and  see  if  you  think  the  same  kind  of  spider  made 
both. 


THE  ORB-WEB 

Teacher's  Story 

F all  the  structures  made 'by  the  lower  creatures,  the  orb- 
web  of  the  spider  is,  beyond  question,  the  most  intricate 
and  beautiful  in  design,  and  the  most  exquisite  in  work- 
manship. The  watching  of  the  construction  of  one  of 
these  webs  is  an  experience  that  brings  us  close  to  those 
mysteries  which  seem  to  be  as  fundamental  as  they  are 
inexplicable  in  the  plan  of  the  universe.  It  is  akin  to 
watching  the  growth  of  a crystal,  or  the  stars  wheeling 
across  the  heavens  in  their  appointed  courses. 

The  orb-web  of  the  large,  black  and  yellow  garden  spider  is,  perhaps, 
the  best  subject  for  this  study,  although  many  of  the  smaller  orbs  are  far 
more  delicate  in  structure.  These  orb-webs  are  most  often  placed  ver- 
tically, since  they  are  thus  more  likely  to  be  in  the  path  of  flying  insects. 
The  number  of  radii,  or  spokes,  differs  with  the  different  species  of 
spiders,  and  they  are  usually  fastened  to  a silken  framework,  which  in 
turn  is  fastened  by  guy-lines  to  surrounding  objects.  These  radii  or 
spokes  are  connected  by  a continuous  spiral  line,  spaced  regularly  except 
at  the  center  or  hub ; this  hub  or  center  is  of  more  solid  silk,  and  is  usually 
surrounded  by  an  open  space;  and  it  may  be  merely  an  irregular  net- 
work, or  it  may  have  wide  bands  of  silk  laid  across  it. 

The  radii  or  spokes,  the  guy-lines,  the  framework  and  the  center  of 
the  web  are  all  made  of  inelastic  silk,  which  does  not  adhere  to  an  object 
that  touches  it.  The  spiral  line,  on  the  contrary,  is  very  elastic,  and  ad- 


Other  Invertebrate-Animal  Study 


479 


heres  to  any  object  brought  in  contact  with  it.  An  insect  which  touches 
one  of  these  spirals  and  tries  to  escape,  becomes  entangled  in  the  neighbor- 
ing lines  and  is  thus  held  fast  until  the  spider  can  reach  it.  If  one  of  these 
elastic  lines  be  examined  with  a microscope,  it  is  a most  beautiful  object. 
There  are  strung  upon  it,  like  pearls,  little  drops  of  sticky  fluid,  which 
render  it  not  only  elastic  but  adhesive. 

Some  species  of  orb-weavers  remain  at  the  center  of  the  web,  while 
others  hide  in  some  little  retreat  near  at  hand.  If  in  the  middle,  the 

spider  always  keeps  watchful  claws  upon 
the  radii  of  the  web  so  that  if  there  is  any 
jarring  of  the  structure  by  an  entrapped 
insect,  it  is  at  once  apprised  of  the  fact;  if 
the  spider  is  in  a den  at  one  side,  it  keeps 
a claw  upon  a trap  line  which  is  stretched 
tightly  from  the  hub  of  the  web  to  the  den, 
and  thus  communicates  any  vibration  of 
the  web  to  the  hidden  sentinel.  When 
the  insect  becomes  entangled,  the  spider 
rushes  out  and  envelops  it  in  a band  of  silk, 
which  feat  it  accomplishes,  by  turning  the 
insect  over  and  over  rapidly,  meanwhile 
spinning  a broad,  silken  band  which 
swathes  it.  It  may  bite  the  insect  before  it 
begins  to  swathe  it  in  silk,  or  afterwards. 
It  usually  hangs  the  swathed  insect  to  the 
web  near  where  it  was  caught,  until  ready 
to  eat  it;  it  then  takes  the  prey  to  the 
center  of  the  web,  if  there  is  where  the 
spider  usually  sits,  or  to  its  den  at  one  side, 
if  it  is  a den-making  species,  and  there 
sucks  the  insect’s  blood,  carefully  throwing 
away  the  hard  parts. 

The  spider  does  not  become  entangled 
in  the  web,  because,  when  it  runs  it  steps 
upon  the  dry  radii  and  not  upon  the  sticky 
spiral  lines.  During  the  busy  season,  the 
spider  is  likely  to  make  a new  web  every 
twenty-four  hours,  but  this  depends  largely 
upon  whether  the  web  has  meanwhile  been 
destroyed  by  large  insects. 

The  spider’s  method  of  making  its  first 
bridge  is  to  place  itself  upon  some  high 
point  and,  lifting  its  abdomen  in  the 
air,  to  spin  out  on  the  breeze  a thread 
of  silk.  ■ When  this  touches  any  object,  it  adheres,  and  the  spider 
draws  in  the  slack  until  the  line  is  “taut;”  it  then  travels  across 
this  bridge,  which  is  to  support  its  web,  and  makes  it  stronger  by  doubling 
the  line.  From  this  line,  it  stretches  other  lines  by  fastening  a thread  to 
one  point,  and  then  walking  along  to  some  other  point,  spinning  the  thread 
as  it  goes  and  holding  the  line  clear  of  the  object  on  which  it  is  walking  by 
means  of  one  of  its  hind  legs.  When  the  right  point  is  reached,  it  pulls 
the  line  tight,  fastens  it,  and  then,  in  a similar  fashion,  proceeds  to  make

another.  It  may  make  its  first  radius  by  dropping  from  its  bridge  to 
some  point  below;  then  climbing  back  to  the  center,  it  fastens  the  line  for 
another  radius,  and  spinning  as  it  goes,  walks  down  and  out  to  some  other 
point,  holding  the  thread  clear  and  then  pulling  it  tight  before  fastening  it. 
Having  thus  selected  the  center  of  the  web,  it  goes  back  and  forth  to  and 
from  it,  spinning  lines  until  all  of  the  radii  are  completed  and  fastened  at 
one  center.  It  then  starts  at  the  center  and  spins  a spiral,  laying  it  onto 
the  radii  to  hold  them  firm.  However,  the  lines  of  this  spiral  are  farther 
apart  and  much  more  irregular  than  the  final  spiral.  Thus  far,  all  of  the 
threads  the  spider  has  spun  are  inelastic  and  not  sticky;  and  this  first,  or 
temporary  spiral  is  used  by  the  spider  to  walk  upon  when  spinning  the 
final  spiral.  It  begins  the  latter  at  the  outer  edge  instead  of  at  the  center, 
and  works  toward  the  middle.  As  the  second  spiral  progresses,  the  spider 
with  its  jaws  cuts  away  the  spiral  which  it  first  made,  and  which  it  has  used 
as  a scaffolding.  A careful  observer  may  often  see  remnants  of  this  first 
spiral  on  the  radii  between  the  lines  of  the  permanent  spiral.  The  spider 
works  very  rapidly  and  will  complete  a web  in  a very  short  time.  The 
final  spiral  is  made  of  the  elastic  and  adhesive  silk.

LESSON  CXII 
The  Orb-web 

Leading  thought — No  structure  made  by  a creature  lower  than  man  is 
so  exquisitely  perfect  as  the  orb-web  of  the  spider. 

Method — There  should  be  an  orb-web  where  the  pupils  can  observe  it, 
preferably  with  the  spider  in  attendance. 

Observations — 1.  Is  the  orb-web  usually  hung  horizontally  or  ver- 
tically ? 

2.  Observe  the  radii,  or  “spokes,”  of  the  web.  How  many  are  there? 
How  are  they  fastened  to  surrounding  objects?  Is  each  spoke  fastened 
to  some  object  or  to  a framework  of  silken  lines? 

3.  Observe  the  silken  thread  laid  around  the  spokes.  Is  it  a spiral 
line  or  is  each  circle  complete?  Are  the  lines  the  same  distance  apart  on 
the  outer  part  of  the  web  as  at  the  center?  How  many  of  the  circling 
lines  are  there  ? 

4.  Is  the  center  of  the  web  merely  an  irregular  net,  or  are  there  bands 
of  silk  put  on  in  zigzag  shape? 

5.  Touch  any  of  the  “spokes”  lightly  with  the  point  of  a pencil. 
Does  it  adhere  to  the  pencil  and  stretch  out  as  you  pull  the  pencil  away  ? 
Touch  one  of  the  circling  lines  with  a pencil  point,  and  see  if  it  adheres  to 
the  point  and  is  elastic.  What  is  the  reason  for  this  difference  in  the 
Stickiness  and  elasticity  of  the  different  kinds  of  silk  in  the  orb-web? 

6.  If  an  insect  touches  the  web,  how  does  it  become  more  entangled 
by  seeking  to  get  away? 

7 . Where  does  the  spider  stay,  at  the  center  of  the  web  or  in  a little 
retreat  at  one  side  ? 

8.  If  an  insect  becomes  entangled  in  the  web,  how  does  the  spider 
discover  the  fact  and  act  ? 

9.  If  the  spider  sits  at  the  middle  of  the  orb,  it  has  a different  method 
for  discovering  when  an  insect  strikes  the  web  than  does  the  spider  that 
hides  in  a den  at  one  side.  Describe  the  methods  of  each.

10.  How  does  the  spider  make  fast  an  insect  ? Does  it  bite  the  insect 
before  it  envelops  it  in  silk?  Where  does  it  carry  the  insect  to  feed  upon 
it? 

1 1 . How  does  the  spider  manage  to  run  about  its  web  without  becom- 
ing entangled  in  the  sticky  thread  ? How  often  does  the  orb-weaver  make 
a new  web  ? 


How  an  Orb-web  is  Made 

Spiders  may  be  seen  mak- 
ing their  webs  in  the  early 
morning  or  in  the  evening. 
Find  an  orb-web  with  a spider 
in  attendance ; break  the  web 
without  frightening  the-  spider 
and  see  it  replace  it  in  the 
early  evening,  or  in  the  morn- 
ing about  daybreak.  An  orb- 
weaver  may  be  brought  into 
the  house  on  its  web,  when  the 
web  is  on  a branch,  and  placed 
where  it  will  not  be  disturbed, 
and  thus  be  watched  at 
leisure. 

Observations — 1.  How 

does  the  spider  manage  to 
place  the  supporting  line  be- 
tween two  points  ? 

2.  Flow  does  it  make  the 
framework  for  holding  the 
web  in  place? 

3.  How  does  it  make  the  first  radius? 

4.  How  does  it  make  the  other  radii  and  select  the  point  which  is 
to  be  the  center  of  the  web  ? 

5.  How  does  it  keep  the  line  which  it  is  spinning 
clear  of  the  line  it  walks  upon? 

6.  After  the  radii  are  all  made,  are  they  fastened  at 

the  center  ? / 

7.  How  and  where  does  the  spider  first  begin  to 
spin  a spiral  ? Are  the  lines  of  this  spiral  close  together 
or  far  apart?  For  what  is  the  first  spiral  used? 

8.  Where  does  it  begin  to  spin  the  permanent 
spiral?  Where  does  it  walk  when  spinning  it?  By 
the  way  it  walks  on  the  first  spiral,  do  you  think  it  is 
sticky  and  elastic?  What  does  it  do  with  the  first 
spiral  while  the  second  one  is  being  finished  ? 

9.  If  the  center  of  the  web  has  a zigzag  ribbon  of  silk,  when  was  it  put 
on? 

10.  How  many  minutes  did  it  take  the  spider  to  complete  the  web?

THE  FILMY  DOME 
Teacher's  Story 

IKE  bubbles  cut  in  half,  these  delicate  domes 
catch  the  light  rays  and  separate  them  like  a 
prism  into  waves  of  rainbow  colors.  One  of 
these  domes  is  usually  about  the  size  of  an 
ordinary  bowl,  and  is  suspended  with  the  open- 
ing on  the  lower  side.  It  is  held  in  place  by 
many  guy-lines  which  attach  it  to  surrounding 
objects.  Above  a filmy  dome  are  always 
stretched  many  crisscrossed  threads  for  some 
distance  up.  These  are  for  the  purpose  of 
hindering  the  flight  of  insects,  so  that  they 
will  fall  into  the  web.  The  little  spider, 
which  always  hangs,  back  downward,  just  below  the  center  of  the 
dome,  rushes  to  its  prey  from  the  lower  side,  pulls  it  through  the 
meshes  of  the  web,  and  feeds  upon  it.  But  any  remains  of  the  insect  or 
pieces  of  sticks  or  leaves  which  may  drop  upon  the  web,  it  carefully  cuts 
out  and  drops  to  the  ground,  mending  the  hole  very  neatly. 

LESSON  CXIII 
The  Filmy  Dome 

Leading  thought — One  little  spider  spins  a filmy  dome,  beneath  the 
apex  of  which  it  hangs,  back  downward,  awaiting  its  prey. 

Method — On  a sunny  day  in  late  summer  or  early  autumn,  while  walk- 
ing along  woodland  paths,  the  careful  observer  is  sure  to  see  suspended 
among  the  bushes  or  in  the  tops  of  weeds,  or  among  dead  branches  of 
young  hemlocks,  the  filmy  dome  webs.  They  are  about  as  large  as  a small 
bowl,  and  usually  so  delicate  that  they  cannot  be  seen  unless  the  sun 
shines  upon  them ; they  are  likely  to  be  exquisitely  iridescent  under  the 
sun’s  rays.  Such  a dome  may  be  studied  by  a class  or  by  the  pupils 
individually. 

Observations — 1.  Where  did  you  discover  the  filmy  dome?  What  is 
the  size  of  the  dome?  Does  it  open  above  or  below?  How  is  it  held  in 
place  ? 

2.  Are  there  many  crisscrossed  threads  extending  above  the  dome? 
If  so,  what  do  you  think  they  are  for? 

3.  Where  does  the  spider  stay?  Is  the  spider  large  and  heavy,  or 
small  and  delicate  ? 

4.  What  does  the  spider  do  if  an  insect  becomes  entangled  in  its  web? 

5.  Throw  a bit  of  stick  or  leaf  upon  a filmy  dome  web,  and  note  what 
becomes  of  it.

BALLOONING  SPIDERS 
Teacher's  Story  ■ 

we  look  across  the  grass  some  warm  sunny  morn- 
ing or  evening  of  early  fall,  we  see  threads  of 
spider  silk  clinging  everywhere;  these  are  not 
regular  webs  for  trapping  insects,  but  are  single 
threads  spun  from  grass  stalk  to  grass  stalk  until 
the  fields  are  carpeted  with  glistening  silk.  We 
have  a photograph  of  a plowed  field,  taken  in 
autumn,  which  looks  likes  the  waves  of  a lake: 
so  completely  is  the  ground  covered  with  spidei 
threads  that  it  shows  the  “path  of  the  sun”  like 
water. 

When  we  see  so  many  of  these  random  threads,  it  is  a sign  that  the 
young  spiders  have  started  on  their  travels,  and  it  is  not  difficult  then  to 
find  one  in  the  act.  The  spiderling  climbs  up  some  tall  object,  like  a twig 
or  a blade  of  grass,  and  sends  out  its  thread  of  silk  upon  the  air.  If  the 
thread  becomes  entangled,  the  spiderling  sometimes  walks  off  on  it,  using 
it  as  a bridge,  or  sometimes  it  begins  again.  If  the  thread  does  not  become 
entangled  with  any  object,  there  is  soon  enough  given  off,  so  that  the 
friction  of  the  air  current  upon  it  supports  the  weight  of  the  body  of  the 
little  creature,  which  promptly  lets  go  its  hold  of  earth  as  soon  as  it  feels 
safely  buoyed  up,  and  off  it  floats  to  lands  unknown.  Spiders  thus  sailing 
through  the  air  have  been  discovered  in  mid-ocean. 

Thus  we  see  that  the  spiders  have  the  same  way  of  distributing  their 
species  over  the  globe,  as  have  the  thistles  and  dandelions.  It  has  been 
asked  what  the  spiders  live  upon  while  they  are  making  these  long  jour- 
neys, especially  those  that  have  drifted  out  to  sea.  The  spider  has  very 
convenient  habits  of  eating.  When  it  finds  plenty  of  food  it  eats  a great 
deal;  but  in  time  of  famine  it  lives  on,  apparently  comfortably,  without 
eating.  One  of  our  captive  spiders  was  mislaid  for  six  months  and  when 
we  found  her  she  was  as  full  of  “grit”  as  ever,  and  she  did  not  seem  to  be 
abnormally  hungry  when  food  was  offered  her. 


“A  noiseless,  patient  spider, 

I mark'd  where,  on  a little  promontory,  it  stood  isolated: 
Mark'd  how  to  explore  the  vacant,  vast  surrounding, 

It  launch'd  forth  filament  out  of  itself : 

Ever  unreeling  them  — ever  tirelessly  speeding  them. 


“ And  you,  0 my  soul,  where  you  stand, 

Surrounded,  surrounded,  in  measureless  oceans  of  space, 

Ceaselessly,  musing,  venturing,  throwing,  seeking  the  spheres  to  connect  them; 
Till  the  bridge  you  will  need  he  form'd  — till  the  ductile  anchor  hold; 

Till  the  gossamer  thread  you  fling  catch  somewhere,  O my  soul." 

— Walt  Whitman.

LESSON  CXIV 
Ballooning  Spiders 

Leading  thought — The  young  of  many  species  of  spiders  scatter  them- 
selves like  thistle  seeds  in  balloons  which  they  make  of  silk. 

Method — These  observations  should  be  made  out  of  doors  during  some 
warm  sunny  day  in  October.  Read  Nature’s  Craftsmen,  McCook,  p.182. 

Observations — 1 . Look  across  the  grass  some  warm  sunny  morning  or 
evening  of  early  fall,  and  note  the  threads  of  spider  silk  gleaming  every- 
where, not  regular  webs,  but  single  threads  spun  from  grass  stalk  to  grass 
stalk,  or  from  one  object  to  another,  until  the  ground  seems  glistening 
with  silk  threads. 

2.  Find  a small  spider  on  a bush,  fence  post,  or  at  the  top  of  some  tall 
grass  stalk;  watch  it  until  it  begins  to  spin  out  its  thread. 

3.  What  happens  to  the  thread  as  it  is  spun  out? 

4.  If  the  thread  does  not  become  entangled  in  any  surrounding  object 
what  happens?  If  the  thread  does  become  entangled,  what  happens? 

5.  How  far  do  you  suppose  a spider  can  travel  on  this  silken  aero- 
plane? Why  should  the  young  spider  wish  to  travel? 


THE  WHITE  CRAB-SPIDER 

Teacher's  Story 

HERE  are  certain  spiders  which  are  crablike  in 
form,  and  their  legs  are  so  arranged  that  they 
can  walk  more  easily  sidewise  or  backward  than 
forward.  These  spiders  spin  no  webs,  but  lie 
in  wait  for  their  prey.  Many  of  them  live  upon 
plants  and  fences  and,  in  winter,  hide  in  pro- 
tected places. 

The  white  crab-spider  is  a little  rascal  that 
has  discovered  the  advantage  of  protective 
coloring  as  a means  of  hiding  itself  from  the 
view  of  its  victims,  until  too  late  to  save  them- 
selves; the  small  assassin  always  takes  on  the 
color  of  the  flower  in  which  it  lies  concealed.  In  the  white  trillium,  it  is 
greenish  white;  while  in  the  golden-rod  its  decorations  are  yellow.  It 
waits  in  the  heart  of  the  flower,  or  in  the  flower  clusters, 
until  the  visiting  insect  alights  and  seeks  to  probe  for  the 
nectar;  it  then  leaps  forward  and  fastens  its  fangs  into  its 
strugglingvictim.  I have  seen  a crab-spider  in  a milkweed 
attack  a bee  three  times  its  size.  This  spider  was  white 
with  lilac  or  purple  markings.  If  disturbed,  the  crab- 
spider  can  walk  off  awkwardly  or  it  may  drop  by  a silken 
thread.  It  is  especially  interesting,  since  it  illustrates 
another  use  for  protective  coloring ; and  also  because  this  species  seems 
to  be  able  to  change  its  colors  to  suit  its  surroundings.

LESSON  CXV 
The  White  Crab-spider 

heading  thought — i.  The  white  crab  spider  has  markings  upon  its 
body  of  the  same  color  as  the  flower  in  which  it  rests  and  is  thus  enabled 
to  hide  in  ambush  out  of  the  sight  of  its  victims — the  insects  which  come 
to  the  flower  for  nectar. 

Method — Ask  the  children  to  bring  one  of  these  spiders  to  school  in  the 
flower  in  which  it  was  found ; note  how  inconspicuous  it  is,  and  arouse  an 
interest  in  the  different  colors  which  these  spiders  assume  in  different 
flowers. 

Observations — i.  What  is  the  shape  of  the  body  of  the  crab-spider? 
Which  of  the  legs  are  the  longest?  Are  these  legs  directed  forward  or 
backward  ? 

2.  How  is  the  body  marked?  What  colors  do  you  find  upon  it? 
Are  the  colors  the  same  in  the  spiders  found  in  the  trilliums,  as  those  in 
other  flowers?  Why  is  this?  Do  you  think  that  the  color  of  the  spider 
keeps  it  from  being  seen  ? 

3.  Place  the  white  spider  which  you  may  find  in  a trillium  in  a 
daffodil,  and  note  if  the  color  changes. 

4.  Do  the  crab-spiders  make  webs?  How  do  they  trap  their  prey?

HOW  THE  SPIDER  MOTHERS  TAKE  CARE  OF  THEIR  EGGS 

Teacher's  Story 

OTECTING  her  eggs  from  the  vicissitudes  of 
the  weather  seems  to  be  the  spider  mother’s 
chief  care;  though  at  the  same  time  and  by 
the  same  means,  she  protects  them  from  the 
attacks  of  predacious  insects.  Many  of  the 
species  make  silken  egg-sacs,  which  are  often 
elaborate  in  construction,  and  are  carefully 
placed  in  protected  situations. 

Often  a little  silvery  disk  may  be  seen 
attached  to  a stone  in  a field.  It  resembles  a 
circular  lichen  on  the  stone, but  if  it  is  examined 
it  is  found  to  consist  of  an  upper,  very  smooth, 
waterproof  coat,  while  below  is  a soft,  downy 
nest,  completely  enfolding  the  spider’s  eggs. 
The  egg-sacs  of  the  cobweb  weavers  are 
often  found  suspended  in  their  webs.  One  of  the  large  orbweavers  makes 
a very  remarkable  nest,  which  it  attaches  to  the  branches  of  weeds  or 
shrubs.  This  sac  is  about  as  large  as  a hickory  nut,  and  opens  like  a vase 
at  the  top.  It  is  very  securely  suspended  by  many  strong  threads  of  silk, 
so  that  the  blasts  of  winter  cannot  tear  it  loose.  The  outside  is  shining 
and  waterproof,  while  inside  it  has  a fit  lining  for  a spiderling  cradle. 

Dr.  Burt  G.  Wilder  studied  the  development  of  the  inmates  of  one  of 
these  nests  by  cutting  open  different  nests  at  different  periods  of  the 
winter.  In  the  autumn,  the  nest  contained  five  hundred  or  more  eggs. 
These  eggs  hatched  in  early  winter  but  it  seemed  foreordained  that  some 
of  the  little  spiders  were  born  for  food  for  their  stronger  brethren.  They 
seemed  resigned  to  their  fate,  for  when  one  of  these  victims  was  seized  by 
its  cannibalistic  brother,  it  curled  up 
its  legs  and  submitted  meekly.  The 
result  of  this  process  was  that,  out  of 
the  five  hundred  little  spiders  hatched 
from  the  eggs,  only  a few  healthy  and 
apparently  happy  young  spiders 
emerged  from  the  nest  in  the  spring,  A wolf-spider  carrying  her  egg-sac. 
sustained  by  the  nourishment  afforded 

them  by  their  own  family,  and  fitted  for  their  life  in  the  outside  world. 

Some  spiders  make  a nest  for  their  eggs  within  folded  leaves,  and  some 
build  them  in  crevices  of  rocks  and  boards. 

The  running  spiders,  which  are  the  large  ones  found  under  stones, 
make  globular  egg-sacs;  the  mother  spider  drags  after  her  this  egg-sac 
attached  to  her  spinnerets;  the  young,  when  they  hatch,  climb  upon  their 
mother’s  back,  and  there  remain  for  a time. 

LESSON  CXVI 
The  Nests  op  Spiders 

Leading  thought — The  spider  mothers  have  many  interesting  ways  oi 
protecting  their  eggs,  which  the/  envelop  in  silken  sacs  and  place  in 
safety. 


48S 


Handbook  of  Nature-Study 


Method — Ask  the  pupils  to  bring  in  all  the  spider  egg-sacs  that  they 
can  find.  Keep  some  of  them  unopened,  and  open  others  of  the  same 
kind,  and  thus  discover  how  many  eggs  are  in  the  sac,  and  how  many 
spiderlings  come  out.  This  is  a good  lesson  for  September  and  October. 

Observations — i . In  what  situation  did  you  find  the  nest?  How  was 
it  protected  from  rain  and  snow.?  To  what  was  it  attached? 

2.  Of  what  texture  is  the  outside  of  the  sac?  Is  the  outside  made  of 
waterproof  silk?  What  is  the  texture  of  the  lining? 

3 . How  many  eggs  in  this  sac  ? What  is  the  color  of  the  eggs  ? When 

do  the  spiderlings  hatch  ? Do  as  many  spiders  come  out  of  the  sac  as 

there  were  eggs?  Why  is  this?

PART  III 


PLANT  LIFE 


HOW  TO  BEGIN  THE  STUDY  OF  PLANTS 
AND  FLOWERS 

HE  only  right  way  to  begin  plant  study  with 
young  children  is  through  awakening  their 
interest  in  and  love  for  flowers.  Most  children 
love  flowers  naturally;  they  enjoy  bringing 
flowers  to  school,  and  here,  by  teaching  the 
recognition  of  flowers  by  name,  may  be  begun 
this  delightful  study.  This  should  be  done 
naturally  and  informally.  The  teacher  may 
say:  “Thank  you,  John,  for  this  bouquet. 

Why,  here  is  a pansy,  a bachelor’s  button,  a 
larkspur  and  a poppy.”  Or,  “Julia  has 
brought  me  a beautiful  flower.  What  is  its  name,  I wonder?”  Then 
may  follow  a little  discussion,  which  the  teacher  leads  to  the  proper  con- 
clusion. If  this  course  is  consistently  followed,  the  children  will  learn 
the  names  of  the  common  flowers  of  wood,  field  and  garden,  and  never 
realize  that  they  are  learning  anything. 

The  next  step  is  to  inspire  the  child  with  a desire  to  care  for  and  pre- 
serve his  bouquet.  The  posies  brought  in  the  perspiring  little  hand  may 
be  wilted  and  look  dejected;  ask  their  owner  to  place  the  stems  in  water, 
and  call  attention  to  the  way  they  lift  their  drooping  heads.  Parents  and 
teachers  should  very  early  inculcate  in  children  this  respect  for  the  rights 
of  flowers  which  they  gather;  no  matter  how  tired  the  child  or  how  dis- 
inclined to  further*  effort,  when  he  returns  from  the  woods  or  fields  or 
garden  with  plucked  flowers,  he  should  be  made  to  place  their  stems  in 
water  immediately.  This  is  a lesson  in  duty  as  well  as  in  plant  study. 


490 


Handbook  of  Nature-Study 


Attention  to  the  behavior  of  the  thirsty  flowers  may  be  gained  by  asking 
the  following  questions: 

1.  When  a plant  is  wilted  how  does  it  look?  How  does  its  stem  act? 
Do  its  leaves  stand  up?  What  happens  to  the  flower? 

2.  Place  the  cut  end  of  the  stem  in  water  and  look  at  it  occasionally 
during  an  hour;  describe  what  happens  to  the  stem,  the  leaves,  the 
blossom. 

3.  To  find  how  flowers  drink,  place  the  stem  of  a wilted  plant  in  red 
ink ; the  next  day  cut  the  stem  across  and  find  how  far  the  ink  has  been 
lifted  into  it. 


HOW  TO  MAKE  PLANTS  COMFORTABLE 

NOTHER  step  in  plant  study  comes  naturally  from 
planting  the  seeds  in  window-boxes  or  garden. 
This  may  be  done  in  the  kindergarten  or  in  the 
primary  grades.  As  soon  as  the  children  have  had 
some  experience  in  the  growing  of  flowers,  they 
should  conduct  some  experiments  which  will  teach 
them  about  the  needs  of  plants.  These  experiments 
are  fit  for  the  work  of  the  second  or  third  grade. 
Uncle  John  says,  “All  plants  want  to  grow;  all  they 
ask  is  that  they  shall  be  made  comfortable.”  The 
following  experiments  should  be  made  vital  and  full  of  interest,  by 
impressing  upon  the  children  that  through  them  they  will  learn  to  make 
their  plants  comfortable. 

Experiment  1.  To  find  out  what  kind  of  soil  plants  love  best  to  grow  in — 
Have  the  children  of  a class,  or  individuals  representing  a class,  prepare 
four  little  pots  or  boxes,  as  follows:  Fill  one  with  rich,  woods  humus,  or 

with  potting  earth  from  a florist’s;  another  with  poor,  hard  soil,  which 
may  be  found  near  excavations ; another  with  clean  sand ; another  with 
sawdust.  Plant  the  same  kind  of  seeds  in  all  four,  and  place  them  where 
they  will  get  plenty  of  light.  Water  them  as  often  as  needful.  Note 
which  plants  grow  the  best.  This  trial  should  cover  six  weeks  at  least 
and  attention  should  now  and  then  be  called  to  the  relative  growth  of  the 
plants. 

Experiment  2.  To  prove  that  plants  need  light  in  order  to  grow. — Fill 
two  pots  with  the  same  rich  soil ; plant  in  these  the  same  kind  of  seeds, 
and  give  them  both  the  same  amount  of  water ; keep  one  in  the  window 
and  place  the  other  in  a dark  closet  or  under  a box, and  note  what  happens. 
Or  take  two  potted  geraniums  which  look  equally  thrifty;  keep  one  in  the 
light  and  the  other  in  darkness.  What  happens? 

Experiment  3.  To  show  that  the  leaves  love  the  light — Place  a geranium 
in  a window  and  let  it  remain  in  the  same  position  for  two  weeks.  Which 
way  do  all  the  leaves  face?  Turn  it.  around,  and  note  what  the  leaves 
have  done  after  a few  days. 

Experiment  4.  To  show  that  plants  need  water — Fill  three  pots  with 
rich  earth,  plant  the  same  kinds  of  seeds  in  each,  and  place  them  all  in  the 
same  window.  Give  one  water  as  it  needs  it,  keep  another  flooded  with 
water,  and  give  the  other  none  at  all.  What  happens  to  the  seeds  in  the 
three  pots? 


Plant  Life 


49i 


The  success  of  these  four  experiments  depends  upon  the  genius  of  the 
teacher.  The  interest  in  the  result  should  be  keen ; every  child  should 
feel  that  every  seed  planted  is  a living  germ  and  that  it  is  struggling  to 
grow;  every  look  at  the  experiments  should  be  like  another  chapter  in  a 
continued  story.  In  the  case  of  young  children,  I have  gone  so  far  as  to 
name  the  seeds,  “Robbie  Radish”  or  “Polly  Peppergrass.”  I did  this  to 
focus  the  attention  of  the  child  on  the ‘efforts  of  this  living  being  to  grow. 
After  the  experiments,  the  children  told  the  story,  personating  each  seed, 
thus:  “I  am  Susie  Sweet  Pea  and  Johnny  Smith  planted  me  in  sand.  I 
started  to  grow,  for  I had  some  lunch  with  me  which  my  mother  put  up 
for  me  to  eat  when  I was  hungry;  but  after  the  lunch  was  all  gone,  I 
could  find  very  little  food  in  the  sand,  although  my  little  roots  reached 
down  and  tried  and  tried  to  find  something  for  me  to  eat.  I finally  grew 
pale  and  could  not  put  out  another  leaf.” 

The  explanations  of  these  experiments  should  be  simple,  with  no 
attempt  to  teach  the  details  of  plant  physiology.  The  need  of  plants  for 
rich,  loose  earth  and  for  water  is  easily  understood  by  the  children;  but 
the  need  for  light  is  not  so  apparent,  and  Uncle  John’s  story  of  the  starch 
factory  is  the  most  simple  and  graphic  way  of  making  known  to  the 
children  the  processes  of  plant  nourishment.  This  is  how  he  tells 
it:  “Plants  are  just  like  us;  they  have  to  have  food  to  make  them 
grow;  where  is  the  food  and  how  do  they  find  it?  Every  green  leaf  is  a 
factory  to  make  food  for  the  plant;  the  green  pulp  in  the  leaf  is 
the  machinery;  the  leaves  get  the  raw  materials  from  the  sap  and 
from  the  air,  and  the  machinery  unites  them  and  makes  them  into 
plant  food.  This  is  mostly  starch,  for  this  is  the  chief  food  of 
plants,  although  they  require  some  other  kinds  of  food  also.  The 
machinery  is  run  by  sunshine-power,  so  the  leaf-factory  can  make 
nothing  without  the  aid  of  light ; the  leaf-factories  begin  to  work  as  soon 
as  the  sun  rises,  and  only  stop  working  when  it  sets.  But  the  starch  has 
to  be  changed  to  sugar  before  the  baby,  growing  tips  of  the  plant  can  use 
it  for  nourishment  and  growth ; and  so  the  leaves,  after  making  the  starch 
from  the  sap  and  the  air,  are  obliged  to  digest  it,  changing  the  starch  to 
sugar;  for  the  growing  parts  of  the  plant  feed  upon  sweet  sap.  Although 
the  starch-factory  in  the  leaves  can  work  only  during  the  daytime,  the 
leaves,  can  change  the  starch  to  sugar  during  the  night.  So  far  as  we 
know,  there  is  no  starch  in  the  whole  world  which  is  not  made  in  the  leaf- 
factories.” 

This  story  should  be  told  and  repeated  often,  until  the  children  realize 
the  work  done  by  leaves  for  the  plants  and  their  need  of  light. 

“The  clouds  are  at  play  in  the  azure  space 
And  their  shadows  at  play  on  the  bright  green  vale. 

And  here  they  stretch  to  the  frolic  chase; 

And  there  they  roll  on  the  easy  gale. 

“ There's  a dance  of  leaves  in  that  aspen  bower , 

There's  a titter  of  winds  in  that  beechen  tree , 

There's  a smile  on  the  fruit  and  a smile  on  the  flower. 

And  a laugh  from  the  brook  that  runs  to  the  sea." 

— Bryant.

HOW  TO  TEACH  THE  NAMES  OF  THE  PARTS  OF  A FLOWER 
AND  OF  THE  PLANT 

HE  scientific  names  given  to  the  parts  of  plants 
have  been  the  stumbling  block  to  many  teachers, 
and  yet  no  part  of  plant  study  is  more  easily 
accomplished.  First  of  all,  the  teacher  should 
have  in  mind  clearly  the  names  of  the  parts 
which  she  wishes  to  teach;  the  illustrations  here 
given  are  for  her  convenience.  When  talking 
with  the  pupils  about  flowers  let  her  use  these 
names  naturally: 

“See  how  many  geraniums  we  have;  the 
corolla  of  this  one  is  red  and  of  that  one  is  pink. 
The  red  corolla  has  fourteen  petals  and  the  pink  one  only  five,”  etc. 

“This  arbutus  which  James  brought  has  a pretty  little  pink  bell  for  a 
corolla.”

“The  purple  trillium  has  a purple  corolla,  the 
white  trillium  a white  corolla;  and  both  have 
green  sepals.” 

The  points  to  be  borne  in  mind  are  that 
children  like  to  call  things  by  their  names 
because  they  are  real  names,  and  the}?"  also  like 
to  use  “grown  up”  names  for  things;  but  they 
do  not  like  to  commit  to  memory  names  which  to 
them  are  meaningless.  Circumlocution  is  a waste 
of  breath;  calling  a petal  a “leaf  of  a flower” 
or  the  petiole  “the  stem  of  a leaf,”  is  like 
calling  a boy’s  arm  “the  projecting  part  of 
James’  body”  or  Molly’s  golden  hair  “the  yellow

top”  to  her  head.  All  the  names  should  be  taught  gradually  by  con- 
stant unemphasized  use  on  the  part  of  the  teacher;  and  if  the  child 
does  not  learn  the  names  naturally  then  do  not  make  him  do  it 
unnaturally. 


The  lesson  on  the  garden,  or  horseshoe  geranium  with  single 
flowers,  is  the  one  to  be  given  first  in  teaching  the  structure  of  a flower 
since  the  geranium  blossom  is  simple  and  easily  understood. 


TEACH  THE  USE  OF  THE  FLOWER 

ROM  first  to  last  the  children  should  be  taught  that  the 
object  of  the  flower  is  to  develop  seed.  They  should 
look  eagerly  into  the  maturing  flower  for  the  growing 
fruit.  Poetry  is  full  of  the  sadness  of  the  fading 
flower,  while  rightly  it  should  be  the  gladness  of  the 
flower  that  fades,  because  its  work  is  done  for  the 
precious  seed  at  its  heart.  The  whole  attention  of  the 
child  should  be  fixed  upon  the  developing  fruit  instead 
of  the  fading  and  falling  petals. 


“In  all  places  then  and  in  all  seasons. 

Flowers  expand  their  light  and  soul-like  wings , 
T eaching  us  by  most  persuasive  reasons, 

How  akin  they  afe  to  human  things." 

— Longfellow.

FLOWERS  AND  INSECT  PARTNERS 

is  undoubtedly  true  that  while  the  processes  of 
cross-pollenation  and  the  complicated  devices  of 
flowers  for  insuring  it  can  only  be  well  taught  to 
older  pupils  and  only  fully  understood  in  the  college 
laboratory,  yet  there  are  a few  simple  facts  which 
even  the  young  child  may  know,  as  follows: 
i.  Pollen  is  needed  to  make  the  seeds  grow;  some 
flowers  need  the  pollen  from  other  flowers  of  the 
same  kind,  to  make  their  seeds  grow;  but  many 
flowers  also  use  the  pollen  from  their  own  flowers  to 
pollenate  their  ovules,  which  grow  into  seeds. 

2 . Flowers  have  neither  legs  like  animals  nor  wings  like  butterflies,  to 
go  after  pollen ; so  they  give  insects  nectar  to  drink  and  pollen  to  eat,  and 
thus  pay  them  for  fetching  and  carrying  the  pollen. 

I taught  this  to  a four-year-old  once  in  the  following  manner : A pine 

tree  in  the  yard  was  sifting  its  pollen  over  us  and  little  Jack  asked  what 
the  yellow  dust  was;  we  went  to  the  tree  and  saw  where  it  came  from, 
then  I found  a tiny  young  cone  and  explained  to  him  that  this  was  a pine 
blossom,  and  that  in  order  to  become  a cone  with  seeds,  it  must  have  some 
pollen  fall  upon  it ; and  we  saw  how  the  wind  sifted  the  pollen  over  it  and 
then  we  examined  a ripe  cone  and  found  the  seeds.  Then  we  looked  at 
the  clovers  in  the  lawn.  They  did  not  have  so  much  pollen  and  they  were 
so  low  in  the  grass  that  the  wind  could  not  carry  it  for  them;  but  right 
there  was  a bee.  What  was  she  doing?  She  was  getting  honey  for  her 
hive  or  pollen  for  her  brood,  and  she  went  from  one  clover  head  to 
another;  we  caught  her  in  a glass  fruit  jar,  and  found  she  was  dusted  with 
pollen  and  that  she  had  pollen  packed  in  the  baskets  on  her  hind  legs ; and 
we  concluded  that  she  carried  plenty  of  pollen  on  her  clothes  for  the 
clovers,  and  that  the  pollen  in  her  baskets  was  for  her  own  use.  After 
that  he  was  always  watching  the  bees  at  work ; and  we  found  afterwards 
that  flowers  had  two  ways  of  telling  the  insects  that  they  wanted  pollen. 
One  was  by  their  color,  for  the  dandelions  and  clovers  hide  their  colors 
during  dark,  rainy  days  when  the  bees  remain  in  their  hives.  Then  we 
found  the  bees  working  on  mignonette,  whose  blossoms  were  so  small  that 
Jack  did  not  think  they  were  blossoms  at  all,  and  we  concluded  that  the 
mignonette  called  the  bees  by  its  fragrance.  We  found  other  flowers 
which  called  with  both  color  and  fragrance;  and  this  insect-flower 
partnership  remained  a factor  of  great  interest  in  the  child’s  mind  ever 
after. 


“ Roly-poly  honey-bee , 

Humming  in  the  clover , 

Under  you  the  tossing  leaves , 

And  the  blue  sky  over , 

Why  are  you  so  busy,  pray? 

Never  still  a minute. 

Hovering  now  above  a flower. 

Now  half  buried  in  it ! ”

THE  RELATION  OF  PLANTS  TO  GEOGRAPHY 

iHERE  should  be  from  first  to  last  a steady  growth  in  the 
intelligence  of  the  child  as  to  the  places  where  certain  plants 
grow.  He  finds  hepaticas  and  trilliums  in  the  woods, 
daisies  and  buttercups  in  the  sunny  fields,  mullein  on  the  dry 
hillsides,  cat-tails  in  the  swamp,  and  water  lilies  floating  on 
the  pond.  This  may  all  be  taught  by  simply  asking  the 
pupils  questions  relating  to  the  soil  and  the  special  condi- 
tions of  the  locality  where  they  found  the  flowers  they  bring  to  schooL

SEED  GERMINATION 

Less  than  three  decades  ago,  this  one  feature  of  plant  life  once  came 
near  “gobbling  up”  all  of  nature-study,  and  yet  it  is  merely  an  incident 
in  the  growth  of  the  plant.  To  sprout  seeds  is  absurd  as  an  object  in 
itself ; it  is  incidental  as  is  the  breaking  of  the  egg-shell  to  the  study  of 
the  chicken.  The  peeping  into  a seed  like  a bean  or  a pea,  to  see  that  the 
plant  is  really  there,  with  its  lunch  put  up  by  its  mother  packed  all 
around  it,  is  interesting  to  the  child.  To  watch  the  little  plant  develop, 
to  study  its  seed-leaves  and  what  becomes  of  them,  to  know  that  they 
give  the  plant  its  first  food  and  to  know  how  a young  plant  looks  and  acts, 
are  all  items  of  legitimate  interest  in  the  study  of  the  life  of  a plant ; in 
fact  the  struggle  of  the  little  plant  to  get  free  from  its  seed-coats  may  be  a 
truly  dramatic  story.  (See  “First  Lessons  with  Plants,”  Bailey,  page 
79).  But  to  regard  this  feature  as  the  chief  object  of  planting  seed  is 
manifestly  absurd. 


Handbook  of  N atur e-Study 


49  <5 

The  object  of  planting  any  seed  should  be  to  rear  a plant  which  shall 
fulfill  its  whole  duty  and  produce  other  seed.  The  following  observa- 
tions regarding  the  germination  of  seeds  should  be  made  while  the 
children  are  eagerly  watching  the  coming  of  the  plants  in  their  gardens  or 
window-boxes : 

1.  Which  comes  out  of  the  seed  first,  the  root  or  the  leaf?  Which 
way  does  the  root  always  grow,  up  or  down?  Which  way  do  the  leaves 
always  grow,  no  matter  which  side  up  the  seed  is  planted  ? 

2.  How  do  the  seed-leaves  try  to  get  out  of  the  seed-coat,  or  shell? 
How  do  the  seed-leaves  differ  in  form  from  the  leaves  which  come  later? 
What  becomes  of  the  seed-leaves  after  the  plant  begins  to  grow?

THE  HEPATICA 
Teacher's  Story 

“ The  wise  men  say  the  hepatica  flower  has  no  petals  but  has  pink,  white  or  purple 
sepals  instead:  and  they  say,  too,  that  the  three  leaflets  of  the  cup  which  holds  the  flower 
are  not  sepals  but  are  bracts;  and  they  offer  as  proof  the  fact  that  they  do  not  grow  close 
to  the  blossom,  but  are  placed  a little  way  down  the  stem.  But  the  hepatica  does  not  care 
what  names  the  wise  men  give  to  the  parts  of  its  blossom:  it  says  as  plainly  as  if  it 
could  talk:  ‘ The  bees  do  not  care  whether  they  are  sepals  or  petals  since  they  are  pretty 

in  color,  and  show  where  the  pollen  is  to  l e found.  I will  teach  the  world  that  bracts  are 
just  as  good  to  wrap  around  flower-buds  as  are  sepals,  and  that  sepals  may  be  just  as 
beautif  ul  as  petals.  Since  my  petticoat  is  pretty  enough  for  a dress  why  should  not  1 
wear  it  thus?  ’ ” — “The  Child’s  Own  Book  of  Wild  Flowers.” 

We  seek  the  hepatica  in  its  own  haunts,  because  there  is  a longing  for 
spring  in  our  hearts  that  awakens  with  the  first  warm  sunshine.  As  we 
thread  our  way  into  sodden  woods,  avoiding  the  streams  and  puddles 
which  are  little  glacial  rivers  and  lakes,  having  their  sources  in  the  snow- 
drifts still  heaped  on  the  north  side  of  things,  we  look  eagerly  for  signs  of 
returning  life.  Our  eyes  slowly  distinguish  among  the  various  shades  of 
brown  in  the  floor  of  the  forest,  a bit  of  pale-blue  or  pink-purple  that  at 
first  seems  like  an  optical  delusion;  but  as  we  look  again  to  make  sure, 
Lo!  it  is  the  hepatica,  lifting  its  delicate  blossoms  above  its  mass  of 
purple-brown  leaves.  These  leaves,  moreover,  are  always  beautiful  in 
shape  and  color  and  suggest  patterns  for  sculpture  like  the  acanthus,  or 
for  rich  tapestries  like  the  palm-leaf  in  the  Orient.  It  warms  the  heai  t to 
see  these  brave  little  flowers  stand  with  their  faces  to  the  sun  and  their 
backs  to  the  snow-drifts,  looking  out  on  a gray-brown  world,  nodding  to 
it  and  calling  it  good. 

The  hepatica  is  forehanded  in  several  ways.  After  the  leaves  have 
fallen  from  the  trees  in  the  autumn  and  let  in  the  sunshine,  it  puts  up  new 
leaves  which  make  food  that  is  stored  in  the  crown  bud ; the  little  flower 
buds  are  then  started,  and  wrapped  cozily,  are  cuddled  down  at  the  very

center  of  the  plant.  These  buds,  perfected  in  the  autumn,  are  ready  to 
stretch  up  and  blossom  when  the  first  warmth  of  spring  shall  reach  them. 
The  stems  and  the  bracts  of  the  flower  are  soft  and  downy,  and  are  much 
more  furry  than  those  which  appear  later;  while  this  down  is  not  for  the 
purpose  of  keeping  the  plant  at  a higher  temperature,  yet  it  acts  as  a 
blanket  to  prevent  too  rapid  transpiration,  which  is  a cooling  process,  and 
thus  it  does,  as  a matter  of  fact,  keep  the  flower  warmer.  As  the  stems 
lift  up,  the  buds  are  bent,  which  position  protects  them  from  the  beating 
storms.  The  hepatica  flowers  are  white,  pink  and  lavender.  The  latter 
are  sometimes  called  “blue.”  The  so-called  “petals”  number  from  six  to 
twelve;  there  are  usually  six.  The  three  outer  ones  are  sepals  and  are 
exactly  like  the  three  inner  ones,  the  petals,  but  may  be  distinguished  by 
their  outside  position  in  the  half-opened  flower.  The  three  green  bracts 
which  encase  the  flower  bud,  and  later  remain  with  the  seed,  are  placed  on 
the  stem  quite  distinctly  below  the  flower.  On  dark  days  and  during  the 
nights,  the  young  blossoms  close ; but  when  they  become  old  and  faded, 
they  remain  open  all  the  time.  Thus,  the  flowers  are  closed  except  when 
bees  are  likefy  to  visit  them ; but  after  they  have  shed  their  pollen,  they 
do  not  need  to  remain  closed  any  longer.  Not  all  hepatica  blossoms  are 
fragrant ; and  those  that  are  so,  lose  their  fragrance  as  their  colors  begin 
to  fade  to  white.  If  a snow-storm  comes,  the  hepatica  blossoms  close  and 
bow  their  heads. 

There  are  many  stamens  with  greenish  white  anthers  and  pollen. 
They  stand  erect  around  the  many  pistils  at  the  center  of  the  flower. 
The  number  of  pistils  varies  from  six  to  twenty-four.  Each  pistil  holds 
aloft  the  little  horseshoe-shaped,  whitish  stigma  and,  if  pollenated.

develops  into  a seed.  The  hepatica  is  a perennial  and  grows  only  in  rich, 
moist  woods.  It  is  so  adapted  to  the  shade,  that  it  dies  if  transplanted 
to  sunny  places.  The  leaves  which  have  passed  the  winter  under  the 
snow  are  rich  purple  beneath,  and  mottled  green  and  purple  above,  mak- 
ing beautiful  objects  for  water-color  drawings.  The  new  leaves  are  put 
forth  in  spring  before  the  leaves  of  the  trees  create  too  much  shade.  In 
the  fall,  after  the  trees  are  bare,  the  leaves  again  become  active.  The 
roots  are  quite  numerous  and  fine. 


Leading  thought — The  hepatica  flower  buds  are  developed  in  the  fall, 
so  as  to  be  ready  to  blossom  early  in  the  spring.  This  plant  lives  only  in 
moist  and  shady  woods. 

Method — The  pupils  should  have  the  questions  before  they  go  into  the 
woods  to  gather  spring  flowers,  and  should  answer  them  individually. 
However,  the  hepatica  plant  may  be  potted  early  in  the  spring,  and  the 
flowers  may  be  watched  during  their  development,  and  studied  in  the 
schoolroom. 

Observations — i.  Where  do  you  find  the  hepaticas?  Do  you  ever 
find  them  in  the  open  fields?  Do  you  ever  find  them  in  the  pine  woods? 

2.  How  do  the  leaves  look  in  early  spring?  Sketch  in  color  one  of 
these  old  leaves.  How  do  the  young  leaves  look?  Are  the  leaves  that 
come  up  late  in  the  spring  as  fuzzy  as  those  that  appear  early?  What 
is  the  difference  in  texture  and  color  between  the  leaves  that  were 
perfected  in  the  fall  and  those  that  appear  in  the  spring? 

3.  Find  a hepatica  plant  before  it  begins  to  blossom.  Look,  if  possi- 
ble, at  its  very  center.  Describe  these  little  flower  buds.  When  were 
they  formed  ?

4.  How  does  the  bud  look  when  it  begins  to  lift  up?  Describe  the 
stems  and  the  three  little  blankets  that  hold  the  bud.  Ask  your  teacher 
how  these  fuzzy  blankets  keep  the  bud  from  being  killed  by  cold. 

5.  Are  the  hepaticas  in  your  woods  all  pink,  or  blue,  or  white?  Do 
those  which  are  at  first  pink  or  blue  fade  to  white  later  ? Do  the  blossoms 
keep  open  during  the  night  and  stormy  weather?  Why  not?  Are  they 
all  fragrant? 

6.  How  many  petals  has  your  hepatica?  Can  you  see  that  the  outer 
ones  are  sepals,  although  they  look  just  like  the  petals?  Peel  back  the 
three  sepal-like  bracts  and  see  that  they  are  not  a part  of  the  flower  at  all 
but  join  the  stem  below  the  flower. 

7.  Describe  the  stamens  in  the  hepatica.  How  many  pistils  are 
there?  Does  each  pistil  develop  into  a seed?  How  do  the  three  bracts 
protect  the  seeds  as  they  ripen  ? 

8.  What  insects  do  you  find  visiting  the  hepaticas? 

9.  Describe  a hepatica  plant  in  the  woods;  mark  it  so  that  you  will 
know  it,  and^  visit  it  occasionally  during  the  summer  and  autumn,  noting 
what  happens  to  it. 


THE  YELLOW  ADDER’S  TONGUE 


Teacher's  Story 


Adder's  tongue. 


“ Once  a prize  was  offered  to  a 
child  if  she  would  find  two  leaves 
of  the  adder's  tongue  that  were 
marked  exactly  alike:  and  she 
sought  long  and  faithfully , but 
the  only  prize  she  won  was  a 
lesson  in  Nature's  book  of  vari- 
ations, where  no  two  leaves  oj 
any  plant,  shrub  or  tree  are 
exactly  alike:  for  even  if  they 
seemed  so  to  our  eyes,  yet  there 
would  exist  in  them  differences 
of  strength  and  growth  too  subtle 
for  us  to  detect.  But  this  child 
was  slow  in  learning  this  great 
fact,  and,  until  she  was  a woman , 
the  adder's  tongue  leaves,  so 
beautifully  embroidered  with 
purple  and  green,  were  to  her  a 
miracle,  revealing  the  infinite 
diversity  of  Nature's  patterns." — ■ 
“The  Child’s  Own  Book  of 
Wild  Flowers.” 

This  little  lily  of  the 
woods  is  a fascinating  plant.

soil  of  our  woodlands;  and  yet  I doubt  if  the  underground  story  of 
these  forest  rugs  is  often  thought  of.  The  leaves  are  twins,  and  to  the 
one  who  plucks  them  carelessly  they  seem  to  come  from  one  slender  stem. 
It  requires  muscle  as  well  as  decision  of  character  to  follow  this  weak 
stem  down  several  inches,  by  digging  around  it,  until  we  find  the  corm 
at  its  base.  A corm  is  the  swollen  base  of  a stem  and  is  bulb-like  in 
form;  but  it  is  not  made  up  of  layers,  as  is  a bulb.  It  is  a store- 
house for  food  and  also  a means  of  spreading  the  species;  for  from 
the  corms  there  grow  little  corms  called  cormels,  and  each  cormel  develops 
a separate  plant.  This  underground  method  of  reproduction  is  the 
secret  of  why  the  leaves  of  the  adder’s  tongue  appear  in  patches,  closely 
crowded  together. 

Only  a few  of  the  plants  in  a “patch”  produce  flowers,  and  it  is  inter- 
esting to  see  how  cleverly  these  lily  bells  hide  from  the  casual  eye.  Like 
many  of  the  lilies,  the  three  sepals  are  petal-like  and  are  identified  as  sepals 

only  by  their  outside  position,  al- 
though they  are  thicker  in  texture. 
They  are  purplish  brown  outside, 
which  serves  to  render  the  flower 
inconspicuous  as  we  look  down  upon 
it;  on  the  inner  side,  they  are  a pure 
yellow,  spotted  with  darker  yellow  near 
where  they  join  the  stem. 
The  three  petals  are  pure- 
yellow,  paler  outside] 
than  in,  and  they  have 
dark  spots  like  the  tiger 
the  heart  of  the  flower; 
they  join  the  stem,  each 
has  on  each  side  an  ear-shaped  lobe. 

The  open  flower  is  bell-shaped; 
and  like  other  bells  it  has  a clapper, 
or  tongue.  This  is  formed  by  six 
downward-hanging  stamens,  the  yel- 
low filaments  of  which  have  broad 
bases  and  taper  to  points  where  the 
oblong  anthers  join  them.  The  anthers 
are  red  or  yellow.  It  is  this  stamen 
clapper  that  the  visiting  insects  must 
cling  to  when  probing  upward  for 
nectar  from  this  flower  at  the  upper 
end  of  the  bell.  The  pale  green  pistil 
is  somewhat  three-sided,  and  the  long 
style  remains  attached  long  after  the 
flower  disappears.  The  flower  is 
slightly  fragrant,  and  it  is  visited  by 
the  queen  bumblebees  and  the  solitary 
bees,  of  which  there  are  many  species.  3

and  splits  into  three  sections  when  ripe.  The 
seeds  are  numerous  and  are  fleshy  and  crescent- 
shaped. 

But  the  adder’s  tongue,  like  many  other  early 
blooming  flowers,  is  a child  of  the  spring.  The 
leaves,  at  first  so  prettily  mottled,  fade  out  to  plain 
green;  and  by  midsummer  they  have  entirely  dis- 
appeared, the  place  where  they  were,  being  covered 
with  other  foliage  of  far  different  pattern.  But 
down  in  the  rich  woods  soil  are  the  plump  globular 
corms  filled  with  the  food  gathered  by  the  spotted 
leaves  during  their  brief  stay,  and  next  spring  two 
pairs  of  spotted  leaves  may  appear  where  there  was 
but  one  pair  this  year.

LESSON  CXVIII 

Adder’s  Tongue,  or  Dog-tooth  Violet 
Leading  thought — The  adder’s  tongue  is  a lily,  and  its  mottled  leaves 
appear  early  in  the  spring,  each  pair  coming  from  a corm  deep  in  the  soil 
below.  It  has  two  ways  of  spreading,  one  underground  by  means  of  new 
corms  growing  from  the  larger  ones,  and  the  other  by  means  of  seeds, 


502  Handbook  of  Nature-Study 

many  of  which  are  probably  perfected  through  the  pollen  carried  by 
insects. 

Method — This  plant  should  be  studied  in  the  woods,  notes  being  made 
on  it  there.  But  a plant  showing  corm,  roots,  leaves  and  blossom  should 
be  brought  to  the  schoolhouse  for  detailed  study,  and  then  planted  in  a 
shady  place  in  the  school  garden? 

Observations — i.  Where  does  the  adder’s  tongue  grow?  Do  you  ever 
find  it  in  open  fields?  How  early  do  you  find  its  leaves  above  ground? 
At  what  time  does  its  blossoms  appear? 

2.  How  many  leaves  has  each  plant?  What  colors  do  you  find  in 
them?  What  is  the  color  of  their  petioles?  Do  the  leaves  remain 
mottled  later  in  the  season? 

3.  Do  the  adder’s  tongue  plants  occur  singly  or  in  patches?  Digout 
a plant  and  see  if  you  can  find  why  the  plants  grow  so  many  together? 

4.  How  far  below  the  surface  of  the  ground  did  you  find  the  corm  or 
bulb-like  growth  ? Is  this  the  root  of  the  plant  ? How  does  it  differ  from 
the  roots  ? How  does  it  differ  from  a bulb  ? Of  what  use  is  it  to  the  plant  ? 

5.  Is  the  flower  lifted  up,  or  is  it  drooping?  What  is  its  general 
shape?  How  many  sepals?  How  would  you  know  they  were  sepals? 
How  do  they  differ  in  color,  outside  and  in,  from  the  petals?  How  are 
the  petals  marked?  Can  you  see  the  lobes  at  the  base  of  each  petal? 
When  sepals  and  petals  are  so  much  alike  the  botanists  call  them  all 
together  the  perianth. 

6.  If  the  perianth,  or  the  sepals  and  petals  together,  make  a bell- 
shaped flower,  what  makes  the  clapper  to  the  bell?  How  do  the  insects 
use  this  clapper  when  they  visit  the  flower?  Do  the  flowers  stay  open 
nights  and  dark  days  ? Why  ? 

7.  How  many  stamens  are  there?  Describe  or  sketch  one,  noting  its 
peculiar  shape.  Are  the  stamens  all  the  same  length?  Can  you  see  the 
pistil  and  its  stigma?  Where  is  it  situated  in  relation  to  the  stamens? 
Do  you  think  the  stigma  is  ready  for  pollen  at  the  time  the  anthers  are 
shedding  it? 

8.  After  the  petals  and  .sepals  fall  what  remains?  How  does  the 
ripe  seed-capsule  look?  How  does  it  open  to  let  out  the  seeds?  Are 
there  many  seeds  in  a capsule?  What  is  their  shape?

BLOODROOT 
Teacher’s  Story 

“What  dime  the  earliest  ferns  unfold, 

And  meadow  cowslips  count  their  gold; 

A countless  multitude  they  stood, 

A Milky  Way  within  the  wood.”  — Danske  Dandridge. 

NLY  a few  generations  ago,  and  this 
land  of  ours  was  peopled  by  those  who 
found  it  fitting  to  paint  their  bodies  to 
represent  their  mental  or  spiritual 
conditions  or  intentions.  For  this 
purpose  they  had  studied  the  plants 
of  our  forests  to  learn  the  secrets  of 
the  dyes  which  they  yielded,  and  a 
dye  that  would  remain  on  the  flesh 
permanently,  or  until  it  wore  off,  was 
highly  prized.  Such  a dye  was  found 
in  the  bloodroot,  a dye  appropriate  in 
its  color  to  represent  a thirst  for  blood ; 
and  with  it  they  made  their  war  paint,  and  with  it  they  ornamented 
their  tomahawks  to  symbolize  their  sanguinary  purpose. 

The  Indian  warriors  have  passed  away  from  our  forests,  and  the  forests 
themselves  are  passing  away,  but  the  bloodroot  still  lingers,  growing 
abundantly  in  rich  moist  woods  or  in  shaded  areas  in  glades,  borders  of 
meadows  and  fence  corners.  Its  beautiful  white  flowers  open  to  the 
morning  sun  in  early  April,  calling  the  hungry  bees  to  come  for  pollen; 
for,  like  man}'-  other  early  flowers,  it  offers  no  nectar.  Probably  many  of 
the  little  wild  bees  prefer  pollen  to  nectar  at  this  time  of  year,  for  it  is  an 


Handbook  of  Nature-Study 


5°4 

important  element  in  the  food  of  all  kinds  of  bee  brood.  But  the  blood- 
root’s  fragile  blossoms  are  elusive  and  do  not  remain  long;  like  their 
relatives,  the  poppies,  their  petals  soon  fall,  and  their  white  masses  dis- 
appear like  the  snow-drifts  which  so  recently  occupied  the  same  nooks. 

The  way  the  bloodroot  leaf  enfolds  the  flower-bud  seems  like  such  an 
obvious  plan  for  protection,  that  we  are  unthinkingly  prone  to  attribute 
consciousness  to  the  little  plants. 

Not  only  does  the  leaf  enfold  the  bud,  but  it  continues  to  enfold  the 
flower  stem  after  the  blossom  opens.  There  are  two  sepals  which  enclose 
the  bud,  but  fall  off  as  the  flower  opens.  There  are  ordinarily  eight  white 
petals,  although  there  may  be  twelve;  usually  every  other  one  of  the 
eight  petals  is  longer  than  its  neighbors,  and  this  makes  the  blossom 
rather  square  than  circular  in  outline.  There  are  many  stamens,  often 
24,  and  the  anthers  are  brilliant  yellow  with  whitish  filaments.  The  two- 
lobed  stigma  opens  to  receive  pollen  before  the  pollen  of  its  own  flower  is 
ripe.  The  s'tigma  is  large,  yellow,  and  set  directly  on  the  ovary,  and  is 
quite  noticeable  in  the  freshly  opened  blossoms.  It  is  likely  to  shrivel 
before  its  home-grown  pollen  is  ripe.  The  blossoms  open  wide  on  sunny 
morning's;  the  petals  rise  up  in  the  afternoon  and  close  at  night,  and  also 
remain  closed  during  dark,  stormy  days  until  they  are  quite  old,  when 
they  remain  carelessly  open;  they  are  now  ready  to  fall  to  the  ground  at 
the  slightest  jar,  leaving  the  oblong,  green  seed-pod  set  on  the  stem  at  a 
neat  bevel,  and  perhaps  still  crowned  with  the  yellowish  stigma.  The 
seed-pod  is  oblong  and  pointed  and  remains  below  the  protecting  leaf. 
There  are  many  yellowish  or  brownish  seeds. 

When  the  plant  appears  above  ground,  the  leaf  is  wrapped  in  a cylinder 
about  the  bud,  and  it  is  a very  pretty  leaf,  especially  the  “wrong  side,” 
which  forms  the  outside  of  the  roll;  it  is  pale  green  with  a network  of 
pinkish  veins,  and  its  edges  are  attractively  lobed;  the  petiole  is  fleshy, 
stout  and  reddish  amber  in  color.  The  flower  stem  is  likewise  fleshy  and 
is  tinged  with  raw  sienna ; the  stems  of  both  leaf  and  flower  stand  side  by 
side,  and  are  held  together  at  the  base  by  two  scapes  with  parallel  veins. 
Later  in  the  season,  the  leaf  having  done  its  full  duty  as  a nurse  waxes 
opulent,  often  measuring  six  inches  across  and  having  a petiole  ten  inches 
long.  It  is  then  one  of  the  most  beautiful  leaves  in  the  forest  carpet,  its 
circular  form  and  deeply  lobed  edges  rendering  it  a fit  subject  for  decora- 
tive design. 

The  rootstock  is  large  and  fleshy,  and  in  it  is  stored  the  food  which 
enables  the  flower  to  blossom  early,  before  any  food  has  been  made  by 
the  new  leaves.  There  are  many  stout  and  rather  short  roots  that  fringe 
the  rootstock.  Once  in  clearing  a path  through  a woodland,  we  happened 
to  hack  off  a mass  of  these  rootstocks,  and  we  stood  aghast  at  the  gory 
results.  We  had  admired  the  bloodroot  flowers  in  this  place  in  the 
spring,  and  we  felt  as  guilty  as  if  we  had  inadvertently  hacked  into  a 
friend. 

LESSON  CXIX 
Bloodroot 

Leading  thought — The  bloodroot  has  a fleshy  rootstock,  in  which  is 
stored  food  for  the  nourishment  of  the  blossom  in  early  spring.  The 
flower  bud  is  at  first  protected  by  the  folded  leaf.  The  juice  of  the  root- 
stock  is  a vivid  light  crimson,  and  was  used  by  Indians  as  a wrar  paint. 


Wild-Flower  Study 


The  juice  is  acrid,  and  the  bloodroot  is  not  relished  as  food  by  grazing 
animals,  but  it  is  used  by  us  as  a medicine. 

Method — The  bloodroot  may,  in  the  fall,  be  transplanted  in  a pot  of 
woods  earth,  care  being  taken  not  to  disturb  its  roots.  It  should  be 
placed  out  of  doors  in  a protected  place  where  it  may  have  natural  condi- 
tions, and  be  brought  to  the  schoolroom  for  study  in  March,  so  that  the 
whole  act  of  the  unfolding  of  leaves  and  flowers  may  be  observed  by  the 
pupils.  Otherwise  the  questions  must  be  given  the  pupils  to  answer  as 
they  find  the  plants  blossoming  in  the  woods  in  April.  The  blossoms  are 
too  fragile  to  be  successfully  transported  for  study  at  home  or  school. 

Observations — i.  At  what  time  of  year  does  bloodroot  blossom?  In 
what  situations  does  it  thrive? 

2.  What  do  we  see  first  when  the  bloodroot  puts  its  head  above  the 
soil?  Where  is  the  flower  bud ? How  is  it  protected  by  the  leaf  ? How 
does  the  leaf  hold  the  flower  stem  after  the  flower  is  in  blossom? 

3 . Study  the  flower.  How  many  sepals  has  it  ? What  is  their  color  ? 
What  is  the  position  of  the  sepals  when  the  flower  is  in  bud?  What  is 
their  position  when  the  flower  opens?  How  many  petals?  What  is 
their  color. and  texture?  Describe  the  position  of  the  petals  in  the  bud 
and  in  the  open  flower.  Look  straight  into  the  flower;  is  its  shape  cir- 
cular or  square  ? 

4.  Do  the  flowers  close  nights  and  during  dark  days?  Do  the  flowers 
longest  open  do  this?  Describe  how  the  petals  and  sepals  fall. 

5.  Describe  the  stamens.  What  is  the  color  of  the  anthers?  Of  the 
pollen?  Describe  the  pistil.  Does  the  two-grooved  stigma  open  before 


Bloodroot.

the  pollen  is  shed,  or  after?  What  insects  do  you  find  visiting  the  blood- 
root? 

6.  Sketch  or  describe  a bloodroot  leaf  as  it  is  wrapped  around  the 
stem  of  the  flower.  How  are  both  flower  stem  and  leaf  petiole  protected 
at  the  base?  Describe  Or  sketch  a leaf  after  it  is  unfolded  and  open. 
Describe  the  difference  between  the  upper  and  lower  surfaces  of  the  leaf. 
What  sort  of  petiole  has  it  ? Break  the  petiole;  what  sort  of  juice  comes 
from  it  ? Describe  and  measure  the  leaf  later  in  the  season ; do  they  all 
have  the  same  number  of  lobes? 

7.  Break  a bit  off  the  root  of  the  plant  and  note  the  color  of  the  juice. 

8.  Compare  the  bloodroot  with  the  poppies;  do  you  find  any  resem- 
blance in  habits?

trilliums,  which  flush  pink  instead  of  fading, 


Teacher's  Story 
It  would  be  well 
for  the  designer  of 
tapestries  to  study 
the  carpets  of  our  for- 
ests for  his  patterns, 
for  he  would  find  there 
a new  carpet  every 
month,  quite  different- 
in  plan  and  design 
from  the  one  spread 
there  , earlier  or  later. 
One  of  the  most 
beautiful  designs  from 
Nature’s  looms  is  a 
trillium  carpet,  which 
is  at  its  best  when 
the  white  trilliums 
are  in  blossom.  It  is 
a fine  study  of  the  ar- 
tistic possibilities  of 
the  triangle  when  re- 
duced to  terms  of 
leaves,  petals  and 
sepals. 

The  trillium  season 
is  a long  one ; it  begins 
in  April  with  the 
purple  wake-robin  or 
birthroot,  the  species 
with  purple,  red,  or 
sometimes  yellowish 
flowers.  The  season 
ends  in  June  with  the 
last  of  the  great  white 
when  old  age  comes  upon 


them. 


Wild-Flower  Study 


5°7 


The  color  of  the  trillium  flower  depends  upon  the  species  studied; 
there  are  three  petals,  and  the  white  and  painted  trilliums  have  the  edges 
of  the  petals  ruffled;  the  red  and  nodding  trilliums  have  petals  and  sepals 
nearly  the  same  size,  but  in  the  white  trillium  the  sepals  are  narrower  and 
shorter  than  the  petals.  The  sepals  are  alternate  the  petals,  so  that  when 
we  look  straight  into  the  flower  we  see  it  as  a six-pointed  star,  three  of  the 
points  being  green  sepals.  The  pistil  of  the  trillium  is  six-lobed.  It  is 
dark  red  in  the  purple  trillium  and  very  large;  in  the  white  species,  it  is 
pale  green  and  smaller;  it  opens  at  the  top  with  three  flaring  stigmas. 
There  are  six  stamens  with  long  anthers,  and  they  stand  between  the 
lobes  of  the  pistil.  The  flower  stalk  rises  from  the  center  where  three 
large  leaves  join.  The  flower  stalk  has  a tendency  to  bend  a little,  and  is 
rather  delicate.  The  three  leaves  have  an  interesting  venation,  and  make 
a good  subject  for  careful  drawing.  The  flower  stem  varies  with  different 
species,  and  so  does  the  length  of  the  stem  of  the  plant,  the  latter  being 

fleshy  and  green  toward  the  top  and  reddish 
toward  the  root.  The  trilliums  have  a 
thick,  fleshy,  and  much  scarred  rootstock 
from  which  extend  rootlets  which  are  often 
corrugated.  The  trilliums  are  perennial, 
and  grow  mostly  in  damp,  rich  woods.  The 
painted  trillium  is  found  in  cold,  damp 
woods  along  the  banks  of  brooks ; the  white 
trillium  is  likely  to  be  found  in  large  num- 
bers in  the  same  locality,  while  the  purple 
trillium  is  found  only  here  and  there.  Flies 
and  beetles  carry  the  pollen  for  the  red 
trillium,  being  attracted  to  it  by  its  rank 
odor,  which  is  very  disagreeable  to  us  but 
very  agreeable  to  them.  The  large  white 
trillium  is  visited  by  bees  and  butterflies. 
The  fruit  of  the  trillium  is  a berry,  that  of 
the  purple  species  is  somewhat  six-lobed 
and  reddish.  In  late  July  the  fruit  of  the 
white  trillium  is  a cone  with  six  sharp 
wings,  or  ridges,  from  apex  to  base,  the 
latter  being  three-quarters  of  an  inch  across. 
These  vertical  ridges  are  not  evenly  spaced, 
and  beneath  them  are  packed  as  closely  as 
possible  the  yellow-green  seeds,  which  are 
as  large  as  homeopathic  pills.  In  cross  section,  it  can  be  seen  that  the 
trillium  berry  is  star-shaped  with  three  compartments,  the  seeds  growing 
on  the  partitions.  This  trillium  fruit  is  very  rough  outside,  but  smooth 
inside,  and  the  dried  stamens  often  still  cling  to  it. 

The  trilliums  are  so  called  from  the  word  triplum,  meaning  three,  as 
there  are  three  leaves,  three  petals,  and  three  sepals. 

LESSON  CXX 
The  Trillium 

Leading  thought — The  trilliums  are  lilies,  and  are  often  called  wood 
lilies,  because  of  their  favorite  haunts.  There  are  several  species,  but

they  are  all  alike  in  that  they  have  three  sepals,  three  petals  and  three 
leaves. 

Method — This  lesson  may  be  given  from  trilliums  brought  to  the  school- 
room by  the  pupils,  who  should  be  encouraged  to  watch  the  development 
of  the  berry  and  also  to  learn  all  the  different  species  common  to  a 
locality. 

Observations — i.  How  many  leaves  has  the  trillium?  How  are  they 
arranged?  Draw  a leaf  showing  its  shape  and  veins.  Describe  the  stem 
of  the  plant  below  the  leaves,  giving  the  length  and  color. 

2.  How  far  above  the  leaves  does  the  flower  stem  or  pedicel  extend? 
Does  the  flower  stand  upright  or  droop?  Describe  or  sketch  the  colors, 
shape  and  arrangement  of  the  petals  and  sepals.  Do  the  petals  have 
ruffled  margins  ? 

3.  Describe  the  pistil  and  the  stigmas.  Describe  the  stamens  and 
how  they  are  placed  in  relation  to  the  pistil. 

4.  Do  the  flowers  remain  open  during  cloudy  days  and  nights? 

5.  What  insects  do  you  find  visiting  the  trilliums?  Do  the  same 
insects  visit  the  purple  and  the  white  trilliums?  What  is  the  difference  in 
odor  between  the  purple  and  the  white  trillium?  Would  this  bring 
different  kinds  of  insects  to  each? 

6.  How  does  the  color  of  the  white  trillium  change  as  the  blossom 
matures  ? What  is  the  color  and  shape  of  the  fruit  of  each  different  species 
of  trillium  ? When  is  the  fruit  ripe  ? 

7.  What  kind  of  a root  have  the  wake-robins?  Do  they  grow  from 
seed  each  year,  or  are  they  perennial?  Where  do  you  find  them  growing?

DUTCHMAN’S  BREECHES  AND  SQUIRREL  CORN 
Teacher's  Story 

‘‘In  a gymnasium  where  things  grow, 

Jolly  boys  and  girls  in  a row, 

Hanging  down  from  cross-bar  stem 
Builded  purposely  for  them. 

Stout  little  legs  up  in  the  air, 

Kick  at  the  breeze  as  it  passes  there ; 

Dizzy  heads  in  collars  wide' 

Look  at  the  world  from  the  underside; 

Happy  acrobats  a-swing, 

At  the  woodside  show  in  early  spring.” 

A.  B.C. 

“And  toward  the  sun,  which  kindlier  burns , 

The  earth  awaking,  looks  and  yearns, 

And  still,  as  in  all  other  Aprils, 

The  annual  miracle  returns.” 

Elizabeth  Akers. 

There  are  many  beautiful  carpets  spread  before  the  feet  of  advancing 
spring,  but  perhaps  none  of  them  are  so  delicate  in  pattern  as  those  woven 
by  these  two  plants  that  spread  their  fernlike  leaves  in  April  and  May. 
There  is  little  difference  in  the  foliage  of  the  two;  both  are  delicate  green 
and  lacclike  above,  and  pale,  bluish  green  on  the  underside.  And  each 
leaf,  although  so  finely  divided,  is,  after  all,  quite  simple;  for  it  has  three 
chief  divisions,  and  these  in  turn  are  divided  into  three,  and  all  the  leaves

come  directly  from  the  root  and  not  from  stems.  These  plants  love  the 
woodlands,  and  by  spreading  their  green  leaves  early,  before  the  trees  are 
in  foliage,  they  have  the  advantage  of  the  spring  sunshine.  Thus  they 
make  their  food  for  maturing  their  seeds,  and  also  store  some  of  it  in  their 
roots  for  use  early  the  following  spring.  By  midsummer  the  leaves  have 
entirely  disappeared,  and  another  carpet  is  spread  in  the  place  which  they 
once  covered. 

Dutchman’s  breeches  and  squirrel  corn 
resemble  each  other  so  closely  that  they  are 
often  confused;  however,  they  are  quite 
different  in  form;  the  “legs”  of  the  Dutch- 
man’s breeches  are  quite  long  and  spread 
wide  apart,  while  the  blossoms  of  the  squir- 
rel corn  are  rounded  bags  instead  of  “legs.” 
The  roots  of  the  two  are  quite  different. 
The  Dutchman’s  breeches  grows  from  a 
little  bulb  made  up  of  grayish  scales,  while 
the  squirrel  corn  develops  from  a round, 
yellow  tuber;  these  yellow,  kernel-like 
tubers  are  scattered  along  the  roots,  each 
capable  of  developing  a plant  next  year. 
The  Dutchman’s  breeches  likes  thin  wood- 
lands and  rocky  hillsides,  but  the  squirrel 
corn  prefers  rich,  moist  woods.  The  blos- 
som of  the  Dutchman’s  breeches  comes  the  earlier  of  the  two.  These 
flowers  are  white  with  yellow  tips,  and  are  not  fragrant.  The  flowers  of 
the  squirrel  corn  are  grayish  with  a tinge  of  magenta, 
and  are  fragrant. 

The  legs  of  the  Dutchman’s  breeches  are  nectar 
pockets  with  tubes  leading  to  them,  and  are  formed 
by  two  petals.  Opposite  these  two  petals  are  two 
others  more  or  less  spoon-shaped,  with  the  spoon 
bowls  united  to  protect  the  anthers  and  stigma. 

There  are  two  little  sepals  which  are  scalelike. 

The  seed  capsule  of  the  Dutchman’s  breeches  is  a 
long  pod  with  a slender,  pointed  end,  and  it  opens 
lengthwise.  The  seed  capsules  of  the  squirrel  corn 
are  similar  and  I have  found  in  one  capsule,  12  seeds, 
which  were  shaped  like  little  kernels  of  corn,  black  in 
color  and  polished  like  patent  leather. 

LESSON  CXXI 
Dutchman’s  Breeches  and  Squirrel  Corn 

Leading  thought — The  Dutchman’s  breeches,  or  “boys  and  girls,”  as 
it  is  often  called,  is  one  of  the  earliest  flowers  of  rich  woodlands.  There 
are  interesting  differences  between  this  flower  and  its  close  relative, 
squirrel  corn.  The  flowers  of  both  of  these  resemble  in  structure  the 
flowers  of  the  bleeding  heart. 

Method — As  the  Dutchman’s  breeches  blossoms  in  April  and  May  and 
the  squirrel  corn  in  May  and  June,  we  naturally  study  the  former  first 
and  compare  the  latter  with  it  in  form  and  in  habits.  The  questions

should  be  given  the  pupils,  for 
them  to  answer  for  themselves 
during  their  spring  walks  in  the 
woodlands. 

Observations — 1.  Where  do 

you  find  Dutchman’s  breeches? 
Which  do  you  prefer  to  call  these 
flowers,  Dutchman’s  breeches  or 
boys  and  girls?  Are  there  leaves 
on  the  trees  when  these  flowers 
are  in  bloom  ? 

2.  Which  blossoms  earlier  in 
the  season,  Dutchman’s  breeches 
or  squirrel  corn?  How  do  the 
flowers  of  the  two  differ  in  shape  ? 
In  odor? 

3.  In  the  flower  of  the  Dutch- 
man’s breeches  find  two  petals 
which  protect  the  nectar.  How 
do  they  look  ? What  part  do  they 
form  of  the  breeches ? Find  two 
other  petals  which  protect  the 
pollen  and  stigma. 

4.  Find  the  two  sepals.  How 
many  bracts  do  you  find  on  the 
flower  stem? 

5.  What  insects  visit  these 
flowers?  Describe  how  they  get 
the  nectar. 

6.  What  sort  of  root  has  the 
Dutchman’s  breeches?  What  is 
the  difference  between  its  root  and 
that  of  the  squirrel  corn  ? Have 
you  ever  seen  squirrels  harvesting 
squirrel  corn?  What  is  the  pur- 

Squirrel  corn.  pose  of  the  kernels  of  the  squirrel 

corn? 

7.  Study  the  leaf.  How  many  main  parts  are  there  to  it?  How  are 
these  parts  divided?  Does  the  leaf  come  straight  from  the  root  or  from  a 
stem?  What  is  the  color  of  the  leaf  above?  Below?  Can  you  distin- 
guish the  leaves  of  the  Dutchman’s  breeches  from  those  of  the  squirrel 
corn? 

8.  Describe  the  seed  capsule  of  Dutchman’s  breeches.  How  does  it 
open?  How  many  seeds  has  it?  Compare  this  with  the  fruit  of  squirrel 
corn  and  describe  the  difference.

JACK-IN-THE-PULPIT 

Teacher's  Story 

“With  hooded  heads  and  shields  of  green. 

Monks  of  the  wooded  glen, 

I know  you  well;  you  are,  I ween, 

Robin  Hood's  merry  men." 

— “Child’s  Own  Book  of  Flowers.” 

IS  little  preacher  is  a prime  favorite 
with  all  children,  its  very  shape, 
like  that  of  the  pitcher  plant,  sug- 
gesting mystery;  and  what  child 
could  fail  to  lift  the  striped  hood  to 
discover  what  might  be  hidden  be- 
neath ! And  the  interest  is  en- 
hanced when  it  is  discovered  that 
the  hood  is  but  a protection  for  the 
true  flowers,  standing  upon  a club- 
shaped  stem,  which  has  been  made 
through  imagination  into  “Jack,” 
the  little  preacher. 

Jack-in-the-pulpit  prefers  wet  lo- 
cations but  is  sometimes  found  on 
dry,  wooded  hillsides;  the  greater 
abundance  of  blossoms  occurs  in  late 
May.  This  plant  has  another  name, 
which  it  earned  by  being  interesting 
below  ground  as  well  as  above.  It 
has  a solid,  flattened,  food-store- 
house called  a corm  with  a fringe  of 
coarse  rootlets  encircling  its  upper  portion.  This  corm  was  used  as  a food 
by  the  Indians,  which  fact  gave  the  plant  the  name  of  Indian  turnip. 
I think  all  children  test  the  corm  as  a food  for  curiosity,  and  retire  from 
the  field  with  a new  respect  for  the  stoicism  of  the  Indian  when  enduring 
torture;  but  this  is  an  undeserved  tribute.  When  raw,  these  corms  are 
peppery  because  they  are  filled  with  minute,  needle-like  spicules  which, 
however,  soften  with  boiling,  and  the  Indians  boiled  them  before  eating 
them. 

Jack-in-the-pulpit  is  a near  cousin  to  the  calla  lily;  the  white  part  of 
the  calla  and  the  striped  hood  over  “Jack”  are  both  spathes,  and  a spathe 
is  a leaf  modified  for  the  protection  of  a flower  or  flowers.  “Jack”  has 
but  one  leg  and  his  flowers  are  set  around  it,  all  safely  enfolded  in  the 
lower  part  of  the  spathe.  The  pistillate  flowers  which  make  the  berries 
are  round  and  greenish,  and  are  packed  like  berries  on  the  stalk;  they 
have  purple  stigmas  with  whitish  centers.  The  pollen-bearing  flowers  are 
mere  little  projections,  almost  white  in  color,  each  usually  bearing  four 
purplish,  cup-like  anthers  filled  with  white  pollen.  Occasionally  both 
kinds  of  flowers  maybe  found  on  one  spadix,  (as  “Jack”  is  called  in  the 
botanies),  the  pollen-bearing  flowers  being  set  above  the  others;  but 
usually  they  are  on  separate  plants.  Professor  Atkinson  has  demon- 


Wild-Flower  Study 


513 


strated  that  when  a plant  be- 
comes very  strong  and  thrifty, 
its  spadix  will  be  set  with  the 
pistillate  flowers  and  its  berries 
will  be  many;  but  if  the  same 
plant  becomes  weak,  it  produces 
the  pollen-bearing  flowers  the 
next  year. 

When  “Jack”  first  appears  in 
the  spring  it  looks  like  a mottled, 
pointed  peg,  for  it  is  well 
sheathed.  Within  this  sheath 
the  leaves  are  rolled  lengthwise 
to  a point,  and  at  the  very  center 
of  the  rolled  leaves  is  a spathe, 
also  rolled  lengthwise,  and  hold- 
ing at  its  heart  the  developing 
flower-buds.  It  is  a most  in- 
teresting process  to  watch  the 
unfolding  of  one  of  these  plants. 
On  the  older  plants  there  are 
two,  or  sometimes  three  leaves, 
each  with  three  large  leaflets;  on  the  younger  plants  there  may  be  but 
one  of  these  compound  leaves,  but  the  leaflets  are  so  large  that  they  seem 
like  three  entire  leaves. 

The  spathes,  or  pulpits,  vary  in  color,  some  being 
maroon  and  white  or  greenish,  and  some  greenish  and 
white.  They  are  very  pretty  objects'  for  water-color 
drawings. 

Small  flies  and  some  beetles  seem  to  be  the  pollen 
carriers  for  this  plant.  Various  ingenious  theories 
have  been  suggested  to  prove  that  our  Jack-in-the- 
pulpit  acts  as  a trap  to  imprison  visiting  insects,  as  does 
the  English  species;  but  I have  studied  the  flowers  in 
every  stage,  and  have  seen  the  insects  crawl  out  of  the 
hoods  as  easily  as  they  crawled  in,  and  by  the  same 
open,  though  somewhat  narrow,  passage  between  the 
spadix  and  the  spathe. 

After  a time  the  spathe  falls  away  showing  the 
globular,  green,  shining  berries.  In  August  even  the 
leaves  may  wither  away,  at  which  time  the  berries  are 
brilliant  scarlet.  Jack-in-the-pulpit  is  a perennial.  It 
does  not  blossom  the  first  year  after  it  is  a seedling.  I 
have  known  at  least  one  case  where  blossoms  were  not 
produced  until  the  third  year.  Below  ground,  the  main  corm  gives  off 
smaller  corms  and  thus  the  plant  spreads  by  this  means  as  well  as  bv 
seeds.

LESSON  CXXII 
Jack-in-the-pulpit 

Leading  thought — The  real  flowers  of  Jack-in-the-pulpit  are  hidden  by 
the  striped  spathe  which  is  usually  spoken  of  as  the  flower.  This  plant 
has  a peppery  root  which  the  Indians  used  for  food. 

Method — The  questions  should  be  answered  from  observation  in  the 
woods ; a single  plant  may  be  dug  up  and  brought  to  school  for  study,  and 
later  planted  in  some  shady  spot  in  the  school  garden. 

Observations — i.  Where  do  you  find  Jack-in-the-pulpit?  Is  the  soil 
dry  or  damp?  Do  you  ever  find  it  in  the  fields? 

2.  How  early  in  the  season  does  this  plant  blossom?  How  late? 

3.  How  does  the  Jack-in-the-pulpit  look  when  it  first  pushes  out  from 
the  ground  ? How  are  its  leaves  rolled  in  its  spring  overcoat  ? 

4.  How  does  the  pulpit,  or  spathe,  look  when  the  plant  first  unfolds? 
Is  its  tip  bent  over  or  is  it  .straight? 

5.  Describe  or  sketch  the  leaves  of  Jack-in-the-pulpit.  How  do  they 
rise  above  and  protect  the  flower?  How  many  leaflets  has  each  leaf? 
Sketch  the  leaflets  to  show  the  venation.  How  do  these  stand  above  the 
flower?  Can  you  find  any  of  the  plants  with  only  one  leaf? 

6.  Why  is  the  spathe  called  a pulpit?  What  are  the  colors  of  the 
spathe?  Are  all  the  spathes  of  the  same  colors? 

7.  Open  up  the  spathe  and  see  the  rows  of  blossoms  around  the 
base  of  the  spadix,  or  if  you  call  the  spadix,  “Jack,”  then  the  flowers 
clothe  his  one  leg.  Are  all  the  blossoms  alike?  Describe,  if  you  can, 
those  flowers  which  will  produce  the  seed'  and  those  which  produce  the 
pollen.  Do  you  find  the  two  on  the  same  spadix  or  on  different  plants? 

8.  What  insects  do  you  find  carrying  the  pollen  for  “Jack?”  Do 
you  know  how  its  seeds  look  in  June?  How  do  they  look  in  August? 
Do  the  leaves  last  as  long  as  the  seeds  ? 

9.  What  sort  of  a root  has  “Jack?”’  How  does  it  taste?  Do  you 
think  the  Indians  boiled  it  before  they  ate  it?  What  other  name  has 
“Jack?”  How  does  the  plant  multiply  below  the  ground? 

10.  Compare  the  Jack-in-the-pulpit  with  the  calla  lily. 

11.  Write  an  English  theme  on  “The  Sermon  that  Jack  Preached  from 
His  Pulpit.”

THE  VIOLET 

Teacher's  Story 

It  is  interesting  to  note  the  flowers  which  have  impinged  upon  the 
imagination  of  the  poets;  the  violet  more  than  most  flowers  has  been 
loved  by  them,  and  they  have  sung  in  varied  strains  of  its  fragrance  and 
lowliness. 

Browning  says: 

“Such  a starved  bank  of  moss, 

‘Till  that  May  morn, 

Blue  ran  the  flash  across; 

Violets  were  born.” 

And  Wordsworth  sings: 

' “A  violet  by  a mossy  stone, 

Half  hidden  from  the  eye; 

Fair  as  a star,  when  only  one 
Is  shining  in  the  sky.“ 

And  Barry  Cornwall  declares  that  the  violet 

“Stands  first  with  most,  but  always  with  the  lover/' 

But  Shakespeare’s  tribute  is  the  most  glowing  of  all,  since  the  charms  of 
both  the  goddesses  of  beauty  and  of  love  are  made  to  pay  tribute  tc  it : 
“Violets  dim,  but  sweeter  than  the  lids  of  Juno’s  eyes,  or  Cytherea’s  breath.” 


Handbook  of  Nature-Study 


5i6 


However,  the  violets  go  on  living  their  own  lives,  in  their  own  way, 
quite  unmindful  of  the  poets.  There  are  many  different  species,  and  they 
frequent  quite  different  locations.  Some  live  in  the  woods,  others  in 
meadows  and  others  in  damp,  marshy  ground.  They  are  divided  into 
two  distinct  groups — those  where  the  leaf-stems  come  directly  from  the 
root,  and  those  where  the  leaves  come  from  a common  stem,  the  latter 
being  called  the  leafy-stemmed  violets.  Much  attention  should  be  given 
to  sketching  and  studying  the  leaf  accurately  of  the  specimens  under 
observation,  for  the  differences  in  the  shapes  of  the  leaves,  in  many 
instances,  determine  the  species;  in  some  cases  the  size  and  shape  of  the 
stipules  determines  the  species;  and  whether  the  leaves  and  stems  are 
downy  or  smooth  is  another  important  characteristic.  In  the  case  of 
those  species  where  the  leaves  spring  from  the  root,  the  flower  stems  rise 
from  the  same  situation;  but  in  the  leafy-stemmed  violets  the  flower 
stems  come  off  at  the  axils  of  the  leaves.  In  some  species  the  flower 
stems  are  long  enough  to  lift  the  flowers  far  above  the  foliage,  while  in 
others  ^hey  are  so  short  that  the  flowers  are  hidden. 

The  violet  has  five 
sepals  and  their  shape 
and  length  is  a distin- 
guishing mark.  There 
are  five  petals,  one  pair 
above,  a pair  one  at  each 
side,  and  a broad  lower 
petal  which  gives  the 
bees  and  butterflies  a 
resting  place  when  they 
ere  seeking  nectar. 
This  lower  petal  is  pro- 
longed backward  into  a 
spur  which  holds  the 
nectar. 

The  spur  forms  the 
nectary  of  the  violet, 
and  in  order  to  reach  the 
sweet  treasure,  which  is 
at  the  rearmost  point  of 
the  nectary,  the  insect 
must  thrust  its  tongue 
through  a little  doer 
guarded  by  both  anthers 
and  pistil;  the  insect 
thus  becomes  laden  with 
pollen,  and  carries  it 
from  flower  to  flower. 
In  many  of  the  species, 
the  side  petals  have  at 
their  bases  a little  fringe 
which  forms  an  arch 
over  the  door  or  throat 
leading  to  the  nectary. 
While  this  is  considered

a guard  to  keep  out  undesirable  insects  like  ants,  I am  convinced  that  it 
is  also  useful  in  brushing  the  pollen  from  the  tongues  of  the  insect  visitors. 

Some  species  of  violets  are 
very  fragrant,  while  others  have 
little  odor.  The  color  of  the 
anthers  also  differs  with  differ- 
ent species.  The  children  should 
be  interested  in  watching  the 
development  of  the  seeds  from 
the  flower.  The  seed-pods  are 
three-lobed,  each  one  of  these 
lobes  dividing  lengthwise,  with  a 
double  row  of  seeds  within. 
Each  lobe  curls  back  and  thus 
scatters  the  seed. 

At  the  base  of  most  of  the 
species  of  violets  can  be  found 
the  small  flowers  which  never 
open;  they  have  no  petals,  but 
within  them  the  pollen  and  the 
pistil  are  fully  developed.  The 
flowers  seem  to  be  developed 
purposely  for  self-pollenation, 
and  in  the  botanies  they  are 
called  cleistogamous  flowers;  in 
some  species  they  are  on  upright 
stems,  in  others  they  lie  flat. 
There  is  much  difference  in  the 
shape  of  the  rootstock  in  the 
different  species  of  violet;  some 
are  delicate  and  others  are 
strong,  and  some  are  creeping.

LESSON  CXXIII 
The  Violet 

Leading  thought — Each  violet 
flower  has  a well  of  nectar,  with 
lines  pointing  to  it  so  that  the  in- 
sects may  find  it.  They  alsc 
have  down  near  their  roots, 
flowers  which  never  open,  which 
are  self-pollenated  and  develop 
seeds. 

Method — To  make  this  work 
of  the  greatest  use  and  interest, 
each  pupil  should  make  a port- 
folio of  the  violets  of  the  locality. 
This  may  be  in  the  form  of 
pressed  and  mounted  specimens, 
or  of  water-color  drawings.  In 
either  case,  the  leaf,  leaf-stem.

5*8 

flower,  flower  stem,  and  rootstock  should  be  shown,  and  each  blossom 
should  be  neatly  labelled  with  name,  locality  and  date.  From  the 
nature-study  standpoint,  a portfolio  of  drawings  is  the  more  desirable, 
since  from  making  the  drawings  the  pupils  become  more  observant  of 
the  differences  in  structure  and  color  which  distinguish  the  species. 
Such  a portfolio  may  be  a most  beautiful  object;  the  cover  of  thick 
cardboard  may  have  an  original,  conventionalized  design  made  from 
the  flowers  and  leaves  of  the  violets.  Each  drawing  may  be  followed 
by  a page  containing  notes  by  the  pupil  and  some  appropriate  quota- 
tion from  botany,  poetry  or  other  literature. 

Observations — 1.  Describe  the  locality  and  general  nature  of  the  soil 
where  the  violet  was  found.  That  is,  was  it  in  the  woods,  dry  fields 
or  near  a stream  ? 

2.  Sketch  or  describe  the  shape  of  the  leaf,  paying  particular  atten- 
tion to  its  margin  and  noting  whether  it  is  rolled  toward  the  stem 
at  its  base.  Is  the  petiole  longer  or  shorter  than  the  leaf?  Does 
the  leaf  stem  spring  directly  from  the  root,  or  does  it  branch  from  another? 
If  the  latter,  are  the  leaves  opposite  or  alternate?  Is  there  a stipule 
where  the  leaf  joins  the  main  stem?  If  so,  is  it  toothed  on  the  edge? 

3.  What  is  the  color  of  the  leaf  above?  Are  the  leaves  and  stems 
downy  and  velvety,  or  smooth  and  glossy  ? 

4.  Does  the  flower  stem  come  from  the  root  of  the  plant,  or  does  it 
grow  from  the  main  stem  at  the  axil  of  the  leaf?  Are  the  flower  stems 
long  enough  to  lift  the  flowers  above  the  foliage  of  the  plant? 

5.  How  many  sepals  has  the  violet?  Are  they  long  or  short ; pointed 
or  rounded  ? How  many  petals  has  the  violet  ? How  are  they  arranged  ? 
Is  the  lower  petal  shaped  like  the  others?  What  is  the  use  of  this  broad 
lower  petal?  Are  there  any  marks  upon  it ? If  you  should  follow  one  of 
these  lines,  where  would  it  lead  to? 

6.  Look  at  the  spur  at  the  back  of  the  flower.  Of  which  petal  is  it  a 
part?  How  long  is  it,  compared  with  the  whole  flower?  What  is  the  use 
of  this  spur? 

7.  Find  the  door  that  leads  to  the  nectar-spur  and  note  what  the 
tongue  of  the  bee  or  butterfly  would  brush  against  when  reaching  for  the 
nectar.  Are  the  side  petals  which  form  the  arch  over  the  door  that  leads 
to  the  nectar  fringed  at  their  bases?  If  so,  what  is  the  use  of  this  fringe? 

8.  What  colors  are  the  petals?  Are  they  the  same  on  both  sides? 
How  are  they  marked  and  veined  ? Are  the  flowers  fragrant  ? 

9.  What  color  are  the  anthers?  What  color  is  the  stigma?  Exam- 
ine a fading  violet,  and  describe  how  the  seed  is  developed  from  the  flower. 

10.  Find  the  seed-pods  of  the  violet.  How  are  the  seeds  arranged 
within  them?  How  do  the  pods  open?  How  are  the  seeds  scattered? 

1 1 . Look  at  the  base  of  the  violet  and  find  the  little  flowers  there  which 
never  open.  Examine  one  of  these  flowers  and  find  if  it  has  sepals,  petals, 
anthers  and  pistil.  Are  these  closed  flowers  on  upright  stems  or  do  the 
stems  lie  flat  on  the  earth  ? Of  what  use  to  the  plant  are  these  little  closed 
flowers  ? 

12.  What  sort  of  rootstock  has  the  violet?  Is  it  short  and  thick  of 
slender?  Is  it  erect,  oblique  or  creeping?

THE  MAY  APPLE,  OR  MANDRAKE 

Teacher's  Story 

HIS  is  a study  of  parasols  and,  therefore,  of 
perennial  interest  to  the  little  girls  who 
use  the  small  ones  for  their  dolls,  and 
with  many  airs  and  graces  hold  the  large 
ones  above  their  own  heads.  And  when 
this  diversion  palls,  they  make  mandarin 
dolls  of  these  fascinating  plants.  This 
is  easily  done  by  taking  one  of  the  small 
plant  umbrellas  and  tying  with  a grass- 
sash  all  but  two  of  the  lobes  closely 
around  the  stem,  thus  making  a dress, 
the  lobes  left  out  being  cut  in  proper 
shape  for  flowing  sleeves ; then  for  a head 
some  other  flower  is  robbed  of  its  flower 
bud,  which  is  put  into  place  and  sur- 
mounted with  a clover  leaflet  hat,  and  a 
pin  is  then  thrust  through  hat,  head  and 
neck  into  the  stem  of  the  dressed  plant; 
the  whole  is  properly  finished  by  placing  a small  umbrella  above  the  little 
green  mandarin. 

The  mandrakes  grow  in  open  places  where  there  is  sun,  and  yet  not  too 
much  of  it;  they  like  plenty  of  moisture,  and  grow  luxuriantly  in  open 
glades  or  in  meadows  or  pastures  bordering  woodlands,  and  they  especially 
rejoice  in  the  fence-corners,  along  roadsides.  The  first  lesson  of  all 
should  be  how  nature  folds  her  little  umbrellas.  Study  the  plants  when 
they  first  put  their  heads  above  ground,  each  parasol  wrapped  in  its  case, 
and  note  how  similarly  to  a real  umbrella  it  is  folded  around  its  stem. 
Later,  after  the  umbrellas  are  fairly  spread,  they  afford  a most  interesting 
study  in  varieties  of  form  and  size.  Some  of  the  parasols  have  only  four 
lobes  while  others  have  many  more.  I have  found  them  with  as  many  as 
nine,  although  the  botanies  declare  seven  to  be  the  normal  number.  One 
of  the  special  joys  afforded  by  nature-study  is  finding  things  different 
from  the  descriptions  of  them  in  the  books. 

One  of  these  little  parasols  is  a worthy  object  for  careful  observation. 
Its  stem  is  stout  and  solid,  and  at  its  base  may  be  seen  the  umbrella-case, 
now  discarded  like  other  umbrella-cases ; the  stem  is  pink  wherever  the 
sun  touches  it,  but  close  up  under  the  leaves  it  is  likely  to  be  green;  it 
ends  at  the  middle  of  the  parasol  by  sending  out  strong,  pale  green,  fuzzy 
ribs  into  each  lobe.  The  lobes  are  narrow  toward  the  stem  but  broad  at 
the  outer  edge,  each  lobe  being  sparsely  toothed  on  its  outer  margins  and 
with  a deep,  smooth  notch  at  the.  center.  From  the  ribs  of  each  lobe 
extend  other  ribs,  an  arrangement  quite  different  from  that  we  find  in 
cloth  umbrellas.  The  lobes  of  the  mandrake  parasol  are  divided  almost 
to  the  center,  and  it  is  therefore  evident  that  it  is  much  better  fitted  for 
protection  from  the  sun  than  from  the  rain.  The  parasol  is  a beautiful 
shining  green  on  the  upper  side,  and  has  a pale  green  lining  that  feels 
somewhat  woolly. 

In  examining  any  patch  of  May  apples,  we  find  that  many  of  the 
parasols  are  double ; the  secret  of  this  is,  that  the  mandrake  baby  needs 


S2°

two  parasols  to  shield  it  from  the  sun ; one  of  these  twin  parasols  is  always 
larger  than  the  other  and  evidently  belongs  to  the  main  stem,  since  its 
stem  is  stouter,  and  it  is  likely  to  have  seven  lobes  while  the  smaller  one 
may  have  but  five.  However,  the  number  of  lobes  varies.  Neither  of 
these  double  parasols  has  its  ribs  extending  out  toward  the  other,  and 
thus  interfering;  instead  of  having  their  “sticks”  at  the  center  of  the 
parasol,  they  are  at  the  side  next  each  other,  exactly  as  if  the  original 
single  stem  had  been  split  and  the  whole  parasol  had  been  torn  in  twain. 

But  of  greatest  interest  is  the  blossom-baby  carried  under  this  double 
parasol.  At  first  it  is  a little,  elongate,  green  ball  on  a rather  stiff  little 
jstem,  which  droops  because  it  wants  to  and  not  because  it  has  to,  and 
'which  arises  just  where  the  two  branches  fork.  One  of  the  strange  things 
about  this  precocious  baby-bud  is,  that  when  the  plant  is  just  coming  from 
the  ground,  the  bud  pushes  its  head  out  from  between  the  two  folded 
parasols,  and  takes  a look  at  the  world  before  it  retires  under  its  green 
sunshade.  As  the  bud  unfolds,  it  looks  as  if  it  had  three  green  sepals, 
each  keeping  its  cup  form  and  soon  falling  off,  as  a little  girl  drops  her  hood 
on  a warm  day;  but  each  of  these  sepals,  if  examined,  will  be  found  to  be 
two  instead  of  one;  the  outer  is  the  outside  of  the  green  hood  while  the 
inner  is  a soft,  whitish  membrane, 

UA  rabbit  skin, 

To  wrap  the  Baby  Bunting  in." 

As  the  greenish  white  petals  spread  out,  they  disclose  a triangular  mass  of 
yellow  stamens  grouped  about  the  big  seed-box,  each  side  of  the  triangle

being  opposite  one  of  the  inner  petals.  After  the  flower  is  fully  open,  the 
stamens  spread  and  each  anther  is  easily  seen  to  be  grooved,  and  each 
edge  of  the  groove  opens  for  the  whole  of  its  length ; but  because  of  its 
shape  and  position,  it  lets  the  pollen  fall  away  from  the  pistil  instead  of 
toward  it;  nor  do  the  tips  of  the  anthers  reach  the  waxy,  white,  ruffled 
stigma.  There  is  no  nectar  in  this  flower;  but  the  big  queen  bumblebee 
likes  the  pollen  for  her  new  nest,  and  she  “bumbles”  around  in  the  flower 
while  getting  her  load,  so  that  she  becomes  well  dusted  with  the  pollen, 
and  thus  carries  it  from  flower  to  flower.  But  the  whole  story  of  the 
pollen  carriers  of  the  May  apple  is,  as  yet,  untold;  and  any  child  who  is 
willing  to  give  time  and  attention  to  discovering  the  different  insects 
which  visit  this  flower,  may  give  to  the  world  valuable  and,  as  yet,  un- 
known facts.  It  is  said  that  a white  moth  is  often  found  hanging  to  the 
flowers,  but  it  is  difficult  to  understand  why  the  moth  should  be  there  if 
the  flower  does  not  have  any  nectar. 

The  seed-vessel  at  the  center  of  the  flower  is  large  and  chunky,  and, 
although  crowned  with  its  ruffled  stigma,  looks  as  if  it  were  surely  going  to 
“grow  up”  into  a May  apple.  There  are  usually  six  wide,  white,  rounded 
petals,  three  on  the  outside  and  three  on  the  inside;  but  sometimes  there 
are  as  many  as  nine.  There  are  usually  twice  as  many  stamens  as  petals, 
but  I have  often  found  thirteen  stamens,  which  is  not  twice  any  possible 
number  of  petals.  The  petals  soon  fall,  and,  safely  hidden  from  the  eyes 
of  enemies,  the  green  fruit — which  is  a berry  instead  of  an  apple — has 
nothing  to  do  but  gather  sweetness,  until  in  July  it  is  as  juicy  and  luscious 
to  the  thirsty  child  as  if  it  were  the  fruit  of  the  gods.  It  is  about  two 
inches  long,  a rich  yellow  in  color,  and  is  sometimes  called  the  “wild 
lemon,”  although  it  is  not  sour.  It  is  also  called  the  hog-apple  because 
the  clever  swine  of  the  South  know  how  to  find  it,  despite  its  parasol. 
Riley  thus  celebrates  this  fruit : 

11  And  will  any  poet  sing  of  a lusher,  richer  thing, 

Than  a ripe  May  apple,  rolled  like  a pulpy  lump  of  gold 

Under  thumb  and  finger  tips;  and  poured  molten  through  the  lips?” 

If  the  May  apple  itself  is  edible,  certainly  its  root  is  not,  except  when 
given  by  physicians  as  a medicine,  for  it  is  quite  poisonous  when  eaten. 
When  we  see  plants  growing  in  colonies  or  patches,  it  usually  means  that 
very  interesting  things  are  going  on  underground  beneath  them,  and  the 
mandrake  is  no  exception  to  this.  Each  plant  has  a running  underground 
stem,  straight  and  brown  and  fairly  smooth;  at  intervals  of  a few  inches, 
there  are  attached  to  it  rosettes  of  stout,  white  roots,  which  divide  into 
tiny,  crooked  rootlets.  There  is  a large  rosette  of  these  roots  under  the 
plant  we  are  studying,  and  we  can  always  find  a rosette  of  them  under  the 
place  where  the  plant  stood  last  year.  Beneath  the  present  plant  we  can 
find  the  bud  from  which  will  grow  the  root-stem  for  the  coming  year.  The 
working  out  of  the  branching  and  the  peculiarities  of  these  root-stems,  is 
an  excellent  lesson  in  this  peculiar  and  interesting  kind  of  plant  reproduc- 
tion. 

LESSON  CXXIV 
The  Mandrake 

Leading  thought— These  interesting  plants  grow  in  colonies  because  of 
the  spreading  of  their  underground  stems.  Their  odor  and  poisonous 
qualities  protect  them  from  being  eaten  by  animals,  and  their  fruit  is 
well  hidden  by  its  green  parasol  until  it  is  ripe.

Handbook  of  N atur e-Study 


Method — Begin  the  study  just  as  the  mandrakes  are  thrusting  their 
heads  up  through  the  soil  in  April,  and  continue  the  work  at  intervals 
until  the  fruit  is  ripe. 

Observations — i.  How  do  the  mandrakes  look  when  they  first  appear 
above  the  ground?  How  are  the  little  umbrellas  folded  in  their  cases? 
What  do  the  cases  look  like?  How  can  you  tell  from  the  first,  the  plants 
which  are  to  bear  the  flowers  and  fruit? 

2.  Study  a patch  of  mandrakes,  and  see  how  many  varieties  of 
parasols  you  can  find?  Do  they  all  have  the  same  number  of  main  ribs 
and  lobes?  How  many  lobes  do  most  of  them  have?  Are  there  more 
single  or  double  parasols  in  the  patch? 

3.  Take  a single  plant  and  study  it  carefully.  What  sort  of  stem  has 
it?  Can  you  find  at  its  base  the  old  umbrella  case?  How  high  is  the 
stem  ? What  is  its  color  at  the  bottom  and  at  the  top  ? How  many  ribs 
does  it  divide  into  at  the  top?  Are  these  ribs  as  smooth  as  the  stem? 
How  does  the  parasol  lining  differ  from  its  outside  in  color  and  feeling? 

4.  Study  the  parasol  lobes.  What  is  their  general  shape?  Are  they 
all  notched  at  the  wide  end?  How  close  to  the  stem  does  the  division 
between  them  extend?  Do  you  not  think  they  are  better  fitted  for  keep- 
ing off  the  sun  than  the  rain  ? 

5.  Take  one  of  the  double  parasols.  Where  is  the  flower  bud  to  be 
found  ? How  is  it  protected  from  the  sun  ? Does  the  stem  divide  equally 
on  each  side  of  it  or  is  one  part  larger  than  the  other?  Are  the  twin 
parasols  of  the  same  size?  How  many  lobes  has  each?  What  are  the 
chief  differences  in  shape  between  one  of  these  twin  parasols  and  one  of 
the  parasols  which  has  no  flower  bud? 

6.  How  does  the  flower  bud  look?  Does  it  droop  because  its  stem  is 
weak  ? What  happens  to  the  green  hood  or  sepals  when  the  flower  opens  ? 
Can  you  find  six  sepals  in  the  hood? 

7.  Does  the  open  flower  bow  downward?  As  the  flower  opens,  what 
is  the  shape  of  the  group  of  stamens  at  the  center?  Are  there  the  same 
number  of  white,  waxy  petals  in  all  the  flowers?  Are  there  always  about 
twice  as  many  stamens  as  petals?  How  do  the  anthers  open  to  shed  the 
pollen?  Do  they  let  the  pollen  fall  away  from  the  raffled  stigma  of  the 
“fat”  little  seed  box  at  the  center  of  the  flower? 

8.  Does  the  flower  have  a strong  odor?  Does  not  the  plant  itself 
give  off  this  odor?  Do  you  think  it  is  pleasant?  Do  the  cattle  eat  the 
mandrake  when  it  is  in  pastures? 

9.  What  insects  do  you  find  visiting  the  mandrake  flowers? 

10.  Do  you  like  the  May  apple  ? When  is  it  ripe?  Cut  a fruit  across 
and  see  how  the  seeds  are  arranged. 

11.  Where  are  mandrakes  found?  Do  they  always  grow  in  patches? 
Dig  up  a few  plants  and  find  why  this  is  so  ? 

12.  Describe  the  underground  stem.  Can  you  find  where  the  last 
year’s  plant  grew ? How  are  the  roots  arranged  upon  the  stem  ? Can  you 
see  places  which  will  produce  the  stem  for  next  year’s  growth  ? How  does 
the  underground  stem  differ  in  appearance  from  the  true  roots?  Why 
must  we  not  taste  of  the  mandrake  root? 

13.  In  late  July,  visit  the  mandrake  patch  again.  Are  there  any 
umbrellas  now?  What  is  left  of  the  plants?  Look  at  the  underground 
stems  again  and  see  if  there  are  new  growths,  and  if  they  are  larger  and 
stored  with  food  for  next  year’s  plants.

Bluets.

THE  BLUETS 
Teacher's  Story 

During  April,  great  patches  of  blue  appear  in  certain  meadows,  seem- 
ing almost  like  reflections  from  the  sky;  and  yet  when  we  look  closely  at 
the  flowers  which  give  this  azure  hue  to  the  fields,  we  find  that  they  are 
more  lavender  than  blue.  The  corolla  of  the  bluet  is  a tube,  spreading 
out  into  four  long,  lavender,  petal-like  lobes ; each  lobe  is  paler  toward  its 
base  and  the  opening  of  the  tube  has  a ring  of  vivid  yellow  about  it,  the 
tube  itself  being  yellow  even  to  its  very  base,  where  the  four  delicate 
sepals  clasp  it  fast  to  the  ovary  until  the  flower  has  done  its  work;  and 
after  the  corolla  has  fallen  the  sepals  remain; 

r standing  guard  over  the  growing  seed. 

If  we  look  carefully  at  the  bluets  we  find  two 
forms  of  flowers:  (a)  Those  with  a two-1  obed 

stigma  protruding  from  the  opening  of  the  flower 
tube,  (b)  Those  where  the  throat  of  the  tube  seems 
closed  by  four  anthers  which  join  like  four  finger- 
tips pressed  together.  In  opening  the  flower, 
& we  observe  that  those  which  have  the  stigmas 
1.  Section  of  a bluet  bios-  protruding  from  the  tube,  have  four  anthers 
som  that  has  the  anthers  fastened  to  the  sides  of  the  tube  about  half-

the  tube.  Thus  an  insect 


524 


Handbook  of  N ature-. Study 


visiting  flower  (a)  gets  her  tongue  dusted  with  pollen  from  the  anthers 
at  the  middle  of  the  tube ; and  this  pollen  is  applied  at  exactly  the  right 
place  on  her  tongue  to  brush  off  against  the  stigmas  of  a flower  of  the 
(b)  form.  While  a bee  visiting  a bluet  of  the  (b)  form  receives  the  pollen 
at  the  base  of  her  tongue,  where  it  is  conveniently  placed  to  be  brushed 
off  by  the  protruding  stigmas  of  the  flowers  of  the  (a)  form. 

This  arrangement  in  flowers  for  the  reciprocal  exchange  of  pollen 
characterizes  members  of  the  primrose  family  also ; it  is  certainly  a very 
clever  arrangement  for  securing  cross-pollen*ation. 

LESSON  CXXV 
The  Bluets 

Leading  thought — The  bluets  have  two  forms  of  flowers,  the  anthers 
and  stigmas  being  placed  in  different  positions  in  the  two,  in  order  to 
secure  cross-pollenation  by  visiting  insects. 

Method — Ask  the  children  to  bring  in  several  bits  of  sod  covered  with 
bluets.  During  recess  let  the  pupils,  with  the  aid  of  a lens  if  necessary, 
find  the  two  different  forms  of  flowers.  Later,  let  each  see  a flower  of 
each  form  with  the  tube  opened  lengthwise. 

Observations — i . Where  do  the  bluets  grow?  Do  they  grow  singly  or 
in  masses?  On  what  kind  of  soil  do  they  grow,  in  woods  or  meadows? 
At  what  time  of  year  do  they  bloom? 

2.  Describe  the  bluet  flower,  its  color,  the  shape  of  its  sepals,  the  form 
of  the  corolla,  the  color  of  the  corolla-tube  and  lobes. 

3.  Where  is  the  nectar  in  the  bluet?  What  color  shows  where  the 
nectar  is  to  be  found? 

4.  Look  directly  into  the  flowers.  Do  you  see  any  with  the  stigmas 
thrust  out  of  the  corolla-tube  ? Is  there  more  than  one  style  ? Has  it  one 
or  two  stigmas?  Open  this  flower-tube  and  describe  where  the  anthers 
are  situated  in  it.  How  many  anthers  are  there? 

5.  Look  for  a flower  where  the  stigmas  do  not  protrude  and  the 
anthers  close  the  throat  of  the  tube.  Where  are  the  stigmas  in  this  flower, 
below  or  above  the  anthers?  Where  are  the  anthers  attached? 

6.  Work  out  this  problem:  How  do  the  insects  gathering  nectar 

from  one  form  of  the  bluets  become  dusted  with  pollen  in  such  a way  as 
to  leave  it  upon  the  stigma  of  the  other  form  of  the  bluet  flower? 

7.  How  many  sepals  are  there?  Do  they  fall  off  when  the  blossom 
falls? 


“So  frail,  these  smiling  babies , 

Near  mossy  pasture  bars , 

Where  the  bloodroot  now  so  coyly 
Puts  forth  her  snowy  stars; 

A nd  the  maple  tall  and  slender , 

With  blossoms  red  and  sweety 
Looks  down  upon  the  bluets 
Close  nestled  at  her  feet. 

'Innocents' , the  children  call  them, — 

These  floral  babies  small, 

Of  Mother  Nature  olden. 

Whose  broad  lap  holds  them  all."

Showy  ladies’  slipper 
Photo  by  Verne  Morton. 


THE  YELLOW  LADY’S  SLIPPER 
Teacher's  Story 

“ Graceful  and  tall  the  slender  drooping  stem, 

With  two  broad  leaves  below. 

Shapely  the  flower  so  lightly  poised  between, 

And  warm  its  rosy  glow.” — Elaine  Goodale. 

These  showy  flowers  look  so  strange  in  our  woodlands  that  we  gaze  at 
them  as  curiously  as  we  might  upon  a veiled  lady  from  the  Orient  who 
had  settled  in  our  midst.  There  is  something  abnormal  and  mysterious 
in  the  shape  of  this  flower,  and  though  it  be  called  the  lady’s  slipper,  yet  it 
would  be  a strange  foot  that  could  fit  such  a slipper ; and  if  it  is  strange 
at  the  first  glance,  it  is  still  more  so  as  we  try  to  compare  it  with  other 
flowers.  There  are  two  long  sepals  that  extend  up  and  down,  the  lower 
one  being  made  up  of  two  grown  together — but  the  “seam”  does  not 
show.  The  sepals  are  yellow,  and  are  wider  than  the  two  long  streamers 
that  extend  out  at  right  angles  to  them,  and  which  are  petals ; the  brighter 
color  of  the  latter,  their  markings  of  reddish  dots,  the  hairs  near  their 
bases,  all  go  to  show  that  these  petals,  although  so  different  in  shape, 
belong  to  the  same  series  as  the  big  lower  petal  which  is  puffed  out  into  a 
sac,  shaped  like  a deep,  long  bowl,  with  its  upper  edges  incurved.  If  we 


Handbook  of  N at ure -Study . 


look  carefully  at  this  bowl,  we  find  two  openings  besides  the  main  one 
these  two  are  near  the  stem,  and  their  edges  are  not  incurved.  Extending 
out  into  each  of  these  openings  is  a strange  little  round  object,  which  is 
an  anther;  but  if  we  try  to  get  pollen  from  this  anther  with  a pencil  or  a 
knife  we  get,  instead  of  powdery  pollen,  a smear  that  sticks  to  what  it 
touches,  like  melted  rubber  or  gum.  The  secret  of  this  is,  that  the  lower 
side  of  the  anther  is  gummy,  and  adheres  to  whatever  touches  it  and 
brings  with  it,  when  pulled  away,  the  mealy  pollen  which  lies  loose  above 
it.  Another  strange  thing  is  that,  if  this  lower  part  of  the  anther  is  not 
carried  away,  it  seems  to  partially  harden  and  opens  downward,  letting 
the  pollen  escape  in  a way  usual  with  other  flowers.  We  have  to  remove 
a side  of  the  bowl  to  see  the  stigma;  it  is  fan-shaped,  and  is  bent  at  right 
angles  to  the  flower  stem;  and  above  it,  as  if  to  protect  it,  is  a stiff  tri- 
angular piece  which  is  really  a strangely  modified  stamen.  I think  one 
reason  why  the  lady’s  slipper  always  is  called  “she”  is  because  of  this 
tendency  on  her  part  to  divert  an  object  from  its  natural  use.  Surely  a 
hairpin  used  for  a paper  knife  or  a monkey-wrench  for  a hammer,  is  not 
nearly  so  feminine  a diversion  as  a stamen  grown  wide  and  long  to  make 
an  awning  above  a stigma. 

The  general-  color  of  the  flower  is  yellow,  and  there  are  some  seductive 
dark  red  spots  on  the  stamen-awning  and  along  the  folded-in  surface  of 

the  petal-sac  which  say  plainly, 
“Come  here,  Madam  Mining-bee, 
and  see  what  these  spots  mean.” 
And  the  little  bee  alights  on  the 
flower  and  soon  crawls  into  the 
well  at  the  center,  the  recurved 
edges  preventing  it  from  return- 
ing by  the  same  door.  At  the 
bottom  of  the  sac  there  are  delec- 
table vegetable  hairs  to  be 
browsed  upon ; if  there  is  nectar, 
I have  never  been  able  to  detect 
it  with  my  coarse  organs  of  taste ; 
and  Mr.  Eugene  Barker  who  has 
examined  hundreds  of  the  flowers 
has  not  been  able  to  detect  the 
presence  of  nectar  in  them  at  any 
stage ; but  he  made  no  histologi- 
cal study  of  the  glands. 

After  a satisfying  meal  the 
bee,  which  is  a lively  crawler, 
seeks  to  get  out  where  it  sees  the 
light  shining  through  one  of  the  openings  near  to  the  stem.  In  doing  this, 
she  presses  her  head  and  back,  first  against  the  projecting  stigma  and 
then  against  the  sticky  anther,  which  smears  he:  with  a queer  kind  of 
plaster;  and  it  sticks  there  until  she  brushes  it  off  on  the  stigma  of 
another  flower,  when  crowding  past  it;  and  there  she  again  becomes 
smeared  with  pollen  plaster  from  this  flower’s  anthers.  Mr.  Barker,  who 
has  especially  studied  these  flowers,  has  found  that  the  little  mining  bees 
of  the  genus  Andrena  were  the  most  frequent  visitors;  he  also  found 
honey-bees  and  one  stray  young  grasshopper  in  the  sacs.  The  mining

bees  which  he  sent  to  me  had  their  backs  plastered  with  the  pollen.  Mr. 
Barker  states  that  the  flowers  are  not  visited  frequently  by  insects,  and 
adds  feelingly;  “My  long  waiting  was  rewarded  with  little  insect  activity, 
aside  from  the  mosquitoes  which  furnished  plenty  of  entertainment.” 

The  ovary  looks  like  a widened  and  ribbed  portion  of  the  flower-stem, 
and  is  hairy  outside ; its  walls  are  thick  and  obscurely  three-angled ; seen 
in  cross-section  the  seeds  are  arranged  in  a triangular  fashion  which  is 
very  pretty. 

The  leaves  of  the  yellow  lady’s  slipper  are  oval  or  elliptic,  with 
smooth  edges  and  parallel  veins ; they  often  have  narrow  veins  between 
each  two  heavier  ones.  The  leaves  are  of  vivid  yellowish  green  and  are 
scattered,  in  a picturesque  manner,  alternately  along  the  stem,  which 
their  bases  completely  clasp.  The  stem  is  somewhat  rough  and  ribbed 
and  is  likely  to  grow  crooked;  it  grows  from  one  to  two  feet  in  height. 
The  roots  are  a mass  of  small  rootlets.  The  species  is  found  in  woods 
and  in  thickets. 

The  pink  moccasin  flower,  also  called  the  stemless  lady’s  slipper  ( C . 
acaule ,)  is  perhaps  prettier  than  the  yellow  species,  and  differs  from  it  in 
several  particulars.  The  sac  opens  by  the  merest  crevice,  and  there  are 
plenty  of  dark-pink  guiding  lines  which  lead  to  the  little  opening  of  the 
well.  The  downward-folded  edges  prevent  the  visiting  insect  from 
getting  out  by  this  door  even  more  surely  than  in  the  other  species.  The 
side  petals  are  not  so  long  as  in  the  yellow  species,  and  they  extend  for- 
ward as  if  to  guide  the  insect  to  the  well  in  the  lower  petal.  The  sepals 
are  greenish  purple,  and  are  likewise  shorter;  and  the  lower  one  is  wide, 
indicating  that  it  is  made  up  of  two  grown  together.  At  the  base  of  the 
ovary  there  is  a pointed  green  bract  or  leaf,  which  lifts  up  and  bends 
above  the  flower.  There  are  but  two  leaves  on  the  stemless  lady’s  slipper; 
they  arise  from  the  base  of  the  stem.  They  are  broadly  ovate,  and  from 
six  to  seven  inches  long.  This  species  grows  in  sandy  or  rocky  woods. 

Another  species  more  beautiful  than  these  is  the  showy  lady’s  slipper, 
which  is  white  with  a pink  entrance  to  the  petal  sac.  This  grows  in 
peaty  bogs,  and  is  not  so  common  as  the  others. 

The  interesting  points  for  observation  in  these  flowers  are  the  careful 
noting  of  the  kinds  of  insects  which  visit  them,  and  how  they  enter  and 
leave  the  “slipper,”  or  sac. 

LESSON  CXXVI 
The  Yellow  Lady’s  Slipper 

Leading  thought — The  moccasin  flower  belongs  to  that  famiiy  of  flowers 
known  as  orchids  which  especially  depend  upon  insects  for  bringing  and 
carrying  pollen,  and  which  have  developed  many  strange  devices  to  secure 
insect  aid  in  pollenation. 

Method — A bouquet  of  lady’s  slippers  should  be  brought  to  the  school- 
room. Children  who  bring  them  should  describe  the  place  where  they 
were  found. 

Observations — 1.  Where  does  the  yellow  lady’s  slipper  grow?  Look 
carefully  at  its  leaves  and  describe  them.  How  do  they  join  the  stem? 
Are  they  opposite  or  alternate  ? 

2.  What  is  there  peculiar  about  the  sepals?  How  many  are  there?

3.  Describe  the  three  petals  and  the  difference  and  likeness  in  their 
form  and  color.  What  is  the  shape  of  the  lower  petal?  Is  there  a hole 
in  this  sac?  Is  there  more  than  one  hole  leading  into  it?  What  is  the 
color  of  the  sac?  Is  there  anything  about  it  to  attract  insects?  If  an 
insect  should  enter  the  mouth  of  the  well  in  the  lower  petal  could  it  easily 
come  out  by  the  same  opening?  Why  not?  Where  do  you  think  it 
would  emerge  ? 

4.  Note  the  two  roundish  objects  projecting  into  the  two  openings  of 
the  sac  near  the  stem.  Thrust  a pencil  against  the  under  side  of  one  of 
these.  What  happens?  How  does  this  pollen  differ  from  the  pollen  of 
ordinary  flowers? 

5.  Cut  away  one  side  of  the  petal-sac  and  find  the  stigma.  What 
shape  is  it?  Where  is  it  situated  with  relation  to  the  anthers?  How  is 
the  stigma  protected  above?  Where  is  the  ovary,  or  seed-box? 

6.  Explain  how  a bee  visiting  these  flowers,  one  after  another,  must 
carry  the  pollen  from  one  to  another  and  deposit  it  on  the  waiting  stigmas. 

7.  How  is  the  insect  attracted?  How  is  it  trapped  and  made  to  do 
the  work? 

8.  Look  at  the  seed-capsule  and  describe  it  from  the  outside.  Cut  it 
across,  and  describe  the  arrangement  of  the  seeds.  How  many  sides  of 
the  seed-capsule  open,  to  let  loose  the  seeds? 

9.  How  many  species  of  lady’s  slippers  do  you  know?  Do  you  know 

the  pink,  or  stemless  species?  How  does  it  differ  from  the  yellow  species 
in  the  following  particulars : The  shape  of  the  sac ; its  color  and  mark- 

ings; the  length  and  shape  of  sepals;  the  number  and  position  of  the 
leaves. 


THE  COMMON  BUTTERCUP 
Teacher's  Story 

“ The  buttercups,  bright-eyed  and  bold , 

Held  up  their  chalices  of  gold 
To  catch  the  sunshine  and  the  dew." 

Buttercups  and  daisies  are  always  associated  in  the  minds  of  the 
children,  because  they  grow  in  the  same  fields;  yet  the  two  are  so  widely 
different  in  structure  that  they  may  reveal  to  the  child  something  of  the 
marvelous  differences  between  common  flowers;  for  the  buttercup  is  a 
single  flower,  while  the  single  daisy  is  a large  family  of  flowers. 

The  buttercup  sepals  are  five  elongated  cups,  about  one-half  as  long  as 
the  petals;  they  are  pale  yellow  with  brownish  tips,  but  in  the  globular 
buds,  they  are  green.  The  petals  are  normally  five  in  number,  but  have 
a tendency  to  double,  so  that  often  there  are  six  or  more;  the  petals  are 
pale  beneath,  but  on  the  inside  they  are  most  brilliant  yellow,  and  shine  as 
if  varnished.  Probably  it  is  due  to  this  luminous  color  that  one  child  is 
able  to  determine  whether  another  likes  butter  or  not,  by  noting  when  the 
flower  is  held  beneath  the  chin,  if  it  makes  a yellow  reflection ; it  would  be 
a sodden  complexion  indeed  that  would  not  reflect  yellow  under  this 
provocation.  Each  petal  is  wedge-shaped,  and  its  broad  outer  edge  is 
curved  so  as  to  help  make  a cuplike  flower;  if  a fallen  petal  be  examined, 
a tiny  scale  will  be  found  at  its  base,  as  if  its  point  had  been  folded  back  a 


Wild-Flower  Study

trifle.  However,  this  is  not  a mere  fold,  but  is  a little  scale  growing  there 
— a scale  with  a mission,  for  beneath  it  is  developed  the  nectar. 

When  the  buttercup  first  opens,  all  of  the  anthers  are  huddled  in  the 
center,  so  that  it  looks  like  a golden  nest  full  of  golden  eggs.  Later  the 
filaments  stretch  up,  lifting  the  anthers  into  a loose,  rounded  tuft,  almost 
concealing  the  bunch  of  pistils  which  are  packed  close  together  beneath 
every  stigma,  like  Bre’r  Rabbitt,  “laying  low.”  Later,  the  filaments 
straighten  back,  throwing  the  anthers  in  a fringy  ring  about  the  pale 
green  pistils;  and  each  pistil  sends  up  a short,  yellowish  stigma.  The 
anthers  open  away  from  the  pistils  and  thus  prevent  self-pollenation  to 
some  degree;  they  also  seem  to  shed  much  of  their  pollen  before  the 
stigmas  are  ready  to  receive  it. 

Sometimes  petals  and  sepals  fall  simultaneously  and  sometimes  first 
one  or  the  other;  but  they  always  leave  the  green  bunch  of  pistils  with  a 
ragged  fringe  of  old  stamens  clinging  to  them.  Later  the  seeds  mature, 
making  a globular  head.  Each  seed  is  a true  akene;  it  is  flattened  and 
has  at  its  upper  end  a short,  recurved  hook  which  may  serve  to  help  it  to 
catch  a ride  on  passers-by.  However,  the  seeds  are  largely  scattered  by 
the  winds. 

The  buttercup  grows  in  sunny  situations,  in  fields  and  along  roadsides, 
but  it  cannot  stand  the  shade  of  the  woods.  It  is  a pretty  plant ; its  long 
stems  are  downy  near  the  bottom,  but  smooth  near  the  flower ; the  leaves 
show  a variety  of  forms  on  the  same  plant;  the  lower  ones  have  many, 
(often  seven)  deeply  cut  divisions,  while  the  upper  ones  may  have  three 
irregular  lobes,  the  middle  one  being  the  longest.  Beetles  are  very  fond 
of  the  nectar  and  pollen  of  buttercups,  and  therefore  are  its  chief  pollen 
carriers ; but  flies  and  small  bees  and  other  insects  also  find  their  food  in 
these  brilliant  colored  cups.

LESSON  CXXVII 
The  Buttercup 

Leading  thought — The  buttercup  grows  with 
the  white  daisies,  in  sunny  places,  but  each 
buttercup  is  a single  flower,  while  each  daisy  is  a 
flower  family. 

Method — Buttercups  brought  by  the  pupils  to 
school  may  serve  for  this  lesson. 

Observations — i . Look  at  the  back  of  a flower 
of  the  buttercup.  What  is  there  peculiar  about 
the  sepals?  How  do  the  sepals  look  on  the 
buttercup  bud?  How  do  they  look  later? 

2.  Look  into  the  flower.  How  many  petals 
are  there?  Are  there  the  same  number  of  petals 
in  all  the  flowers  of  the  same  plant?  What  is  the 
shape  of  a petal?  Compare  its  upper  and  lower 
sides.  Take  a fallen  petal,  and  look  at  its  pointed  base  with  a lens  and 
note  what  is  there. 

3.  How  do  the  stamens  look?  Do  you  think  you  can  count  them? 
When  the  flower  first  opens  how  are  the  stamens  arranged?  How,  later? 
Do  the  anthers  open  towards,  or  away,  from  the  pistils  ? 

4.  Note  the  bunch  of  pistils  at  the  center  of  the  flower.  How  do  they 
look  when  the  flower  first  opens?  How,  later? 

5 . When  the  petals  fall,  what  is  left  ? Can  you  see  now  how  each  little 
pistil  will  develop  into  a seed? 

6.  Describe  the  seed-ball  and  the  seed. 

7.  Look  at  the  buttercup’s  stems.  Are  they  as  smooth  near  the  base 
as  near  the  flower?  Compare  the  upper  leaf  with  the  lower  leaf,  and  note 
the  difference  in  shape  and  size. 

8.  Where  do  the  buttercups  grow?  Do  we  find  them  in  the  woods? 
What  insects  do  you  find  visiting  the  flowers? 


THE  EVENING  PRIMROSE 

Teacher's  Story 

“ Children  came 

To  watch  the  primrose  blow.  Silent  they  stood , 

Hand  clasped  in  hand , in  breathless  hush  around, 

And  saw  her  shyly  doff  her  soft  green  hood 
And  blossom — with  a silken  burst  of  sound.” 

— Margaret  Deland. 

To  the  one  who  has  seen  the  evening  primrose  unfold,  life  is  richer  by  a 
beautiful,  mysterious  experience.  Although  it  may  be  no  more  wonder- 
ful than  the  unfolding  of  any  other  flower,  yet  the  suddenness  of  it  makes 
it  seem  more  marvelous.  For  two  or  three  days  it  may  have  been  getting 
ready;  the  long  tube  which  looks  like  the  flower  stem  has  been  turning

yellow;  pushing  up  be- 
tween two  of  the  sepals, 
which  clasp  tips  beyond 
it,  there  appears  a row 
of  petals.  Then  some 
warm  evening,  usually 
about  sunset,  but  vary- 
ing from  four  o’clock  in 
the  afternoon  to  nine  or 
ten  in  the  evening,  the 
petals  begin  to  unfurl; 
they  are  wrapped  around 
each  other  in  the  bud  as 
an  umbrella  is  folded, 
and  thus  one  edge  of 
each  petal  becomes  free 
’first.  The  petal  first  in 
freeing  its  edge  seems  to 
be  doing  all  the  work, 
but  we  may  be  sure  that 
all  the  others  are  push- 
ing for  freedom;  little 
by  little  the  sepals  are 
pushed  downward,  until 
their  tips,  still  clasped, 
are  left  beneath ; and 
the  petals  now  free,  sud- 
denly flare  open  before 
our  delighted  eyes,  with 
a movement  so  rapid 
that  it  is  difficult  for  us 
not  to  attribute  to  them 
consciousness  of  action.  Three  or  four  of  these  flowers  may  open  on  a 
plant  the  same  evening;  and  they,  with  their  fellows  on  the  neighboring 
plants,  form  constellations  of  starry  bloom  that  invite  attention  from  the 
winged  creatures  of  the  twilight  and  the  night.  There  is  a difference  in 
the  time  required  for  a primrose  flower  to  unfold,  probably  depending 
upon  its  vigor;  once  I watched  for  half  an  hour  to  see  it  accomplished, 
and  again  I have  seen  it  done  in  two  or  three  minutes.  The  garden 
species  seems  to  unfold  more  rapidly  than  the  wild  species,  and  is  much 
more  fragrant.  The  rapidity  of  the  opening  of  the  blossom  depends  upon 
the  petals  getting  free  from  the  sepals,  which  seem  to  try  to  repress  them. 
The  bud  is  long,  conical,  obscurely  four-sided,  and  is  completely  covered 
by  the  four  sepals,  the  tips  of  which  are  cylindrical  and  twisted  together; 
this  is  an  interesting  habit,  and  one  wonders  if  they  hold  the  petals  back 
until  the  latter  are  obliged  to  burst  out  with  the  force  of  repressed 
energy;  after  they  let  go  of  the  petals,  they  drop  below  the  flower 
angularly,  and  finally  their  tips  open  and  each  sepal  turns  back  length- 
wise along  the  seed-tube. 

The  four  lemon-yellow  petals  are  broad,  with  the  outer  margin 
notched.  The  eight  stamens  are  stout,  and  set  one  at  the  middle  of  each 
petal  and  one  between  each  two  petals.  The  long,  pale  yellow  anthers

discharge  their  pollen  in  cobwebby  strings.  When  the  flower  first  opens, 
the  stigma  is  egg-shaped  and  lies  below  the  anthers ; later,  it  opens  into  a 
cross  and  usually  hangs  off  at  one  side  of  the  anthers.  If  we  try  to  trace 
the  style  back  to  the  ovary,  we  find  that  it  extends  down  into  what  seems 
to  be  the  very  base  of  the  flower  stem,  where  it  joins  the  main  stem.  This 
base  is  enlarged  and  ribbed  and  is  the  seed-box,  or  ovary.  The  tube  is 
rich  in  nectar,  but  only  the  long  sucking-tubes  of  moths  can  reach  it, 
although  I have  sometimes  seen  the  ubiquitous  bees  attempting  it.  The 
butterflies  may  take  the  nectar  in  the  daytime,  for  the  blossoms  of  the 
wild  species  remain  open,  or  partially  open,  for  a day  or  two.  But  the 
night-flying  moths  which  love  nectar  have  the  first  chance,  and  it  is  on 
them  the  flower  depends  for  carrying  its  pollen,  threaded  on  filmy  strings. 

There  are  times  when  we  may  find  the  primrose  blossoms  with  holes  in 
the  petals,  which  make  them  look  very  ragged.  If  we  look  at  such  plants 
carefully,  we  may  find  the  culprit  in  the  form  of  a green  caterpillar  very 
much  resembling  the  green  tube  of  the  bud ; and  we  may  conclude,  as  Dr. 
Asa  Fitch  did,  that  this  caterpillar  is  a rascal,  because  it  crawls  out  on  the 
bud-ends  and  nibbles  into  them,  thus  damaging  several  flowers.  But 
this  is  only  half  the  story.  Later  this  caterpillar  descends  to  the  ground, 
digs  down  into  it  and  there  changes  to  a pupa ; it  remains  there  until  the 
next  summer,  then,  from  this  winter  cell,  emerges  an  exquisitely  beautiful 
moth  called  the  Alaria  florida;  its  wings  expand  about  an  inch,  and  all 
except  the  outer  edges  of  the  front  wings  are  rose-pink,  slightly  mottled 
with  lemon-yellow,  which  latter  color  decorates  the  outer  margins  for 
about  one-quarter  of  their  length ; the  body  and  hind-wings  are  whitish 
and  silky,  the  face  and  antennae  are  pinkish.  Coiled  up  beneath  the  head 
is  a long  sucking-tube  which  may  be  unfolded  at  will.  This  moth  is  the 
special  pollen-carrier  of  the  evening  primrose;  it  flies  about  during  the 
evening,  and  thrusts  its  long,  tubular  mouth  into  the  flower  to  suck  the 
nectar,  meanwhile  gathering  strings  of  pollen  upon  the  front  part  of  its 
body.  During  the  day,  it  hides  within  the  partially  closed  flower,  thus 
carrying  the  pollen  to  the  ripened  stigmas,  its  colors  meanwhile  protecting 
it  almost  completely  from  observation.  The  fading  petals  of  the  prim- 
rose turn  pinkish,  and  the  pink  color  of  the  moth  renders  it  invisible  when 
in  the  old  flowers,  while  the  lemon-yellow  tips  of  its  wings  protruding  from 
a flower  still  fresh  and  yellow,  forms  an  equally  perfect  protection  from 
observation. 

The  evening  primrose  is  an  ornamental  plant  in  both  summer  and 
winter.  It  is  straight,  and  is  ordinarily  three  or  four  feet  tall,  although  it 
sometimes  reaches  twice  that  height.  It  is  branched  somewhat,  the 
lower  portion  being  covered  with  leaves  and  the  upper  portion  bearing  the 
flowers.  The  leaves  are  pointed  and  lanceolate,  with  few  whitish  veins. 
The  leaf  edges  are  somewhat  ruffled  and  obscurely  toothed,  especially  in 
the  lower  leaves.  The  leaves  stand  up  in  a peculiar  way,  having  a short, 
pink  petiole,  which  is  swollen  and  joins  the  stalk  like  a bracket.  The 
upper  leaves  are  narrower ; the  leafy  bracts  at  the  base  of  the  flower  grow 
from  the  merest  slender  leaflet  at  the  base  of  the  bud,  to  a leaf  as  long  as. 
the  seed-pod,  when  the  flower  blooms. 

The  seed-capsules  are  four-sided,  long  and  dark  green.  In  winter  they 
are  crowded  in  purplish-brown  masses  on  the  dry  stalks,  each  one  a grace- 
ful vase  with  four  flaring  tips.  At  the  center  of  each  there  projects  a 
needlelike  point;  and  within  the  flaring,  pale,  satin-lined  divisions  of

these  urns,  we  may  see  the  brown  seeds  which  are  tossed  by  the  winter 
winds  far  and  near.  The  young  plants  develop  into  vigorous  rosettes 
during  the  late  summer  and  autumn,  and  thus  discreetly  pass  the  winter 
under  the  snow  coverlet. 

LESSON  CXXVIII 
The  Evening  Primrose 


Winter  rosette  of  evening  primrose. 
Photo  by  Verne  Morton. 


Leading  thought — Some  flowers  have  developed  the  habit  of  relying  on 
the  night-flying  insects  for  carrying  their  pollen.  The  evening  primrose 
is  one  of  these ; its  flowers  open  in  the  evening  and  their  pale  yellow  color 
makes  them  noticeable  objects  in  the  twilight,  and  even  in  the  dark. 

Method — The  form  of  the  evening  primrose  may  be  studied  from 
plants  brought  to  the  schoolroom ; but  its  special  interest  lies  in  the  way 
its  petals  expand  in  the  evening,  so  the  study  should  be  continued  by  the 
pupils  individually  in  the  field.  This  is  one  of  the  plants  which  is  an 
especially  fit  subject  fQr  the  summer  note-book;  but  since  it  blossoms 
very  late  and  the  plants  are  available  even  in  October,  it  is  also  a con- 
venient plant  to  study  during  the  school  year.  The  garden  species  is 
well  adapted  for  this  lesson. 

Observations — i.  Look  at  the  plant  as  a whole.  How  tall  is  it?  Is 
the  stem  stiff  and  straight?  Where  do  you  find  it  growing?  Does  it 
grow  in  the  woods? 

2.  Are  the  leaves  near  the  base  the  same  shape  as  those  at  the  top  of 
the  plant?  What  is  their  shape?  Are  the  edges  toothed?  What  is 
there  peculiar  about  the  veins?  How  do  the  leaves  join  the  stem?  How 


534  Handbook  of  N ature-Study 

do  the  leaves  look  which  are  at  the  base  of  the  flower  stem  ? Those  at  the 
base  of  the  buds? 

3.  Where  on  the  plant  do  the  flowers  grow  ? Which  flowers  blossom 
first,  those  above  or  below?  Take  a bud  nearly  ready  to  open;  what  is 
there  peculiar  in  the  appearance  of  the  bud  stem?  What  is  the  general 
shape  of  the  bud  ? Describe  the  sepals.  Look  at  their  tips  carefully,  and 
see  how  they  hold  together.  Cut  a bud  across  and  see  how  the  petals  are 
folded  within  it. 

4.  Take  an  open  flower;  where  are  the  sepals  now?  Describe  the 
open  petals,  their  shape  and  color. 

5.  How  many  stamens  are  there?  How  are  they  placed?  What  is 
the  shape  of  the  anthers?  How  does  the  pollen  look? 

6.  What  is  the  shape  and  the  position  of  the  stigma  in  the  freshly 
opened  flower?  Later?  Open  the  flower-tube  and  find  how  far  down  the 
style  extends.  Where  is  the  ovary?  How  does  the  ovary  look  on  the 
outside?  Taste  the  opened  tube ; can  you  detect  the  nectar?  What  sort 
of  a tongue  must  an  insect  have  to  reach  this  nectar?  How  do  the  fading 
flowers  look  and  act  ? 

7 . Describe  the  seed-pod.  Cut  it  across,  and  see  how  many  compart- 
ments there  are  within  it.  How  are  the  seeds  arranged  in  it?  How  do 
the  pods  open  and  how  are  the  seeds  scattered? 

8.  Watch  the  flower  of  the  evening  primrose  open,  and  describe  the 
process  carefully.  At  what  hour  did  it  open?  What  was  the  movement 
of  the  petals?  Can  you  see  how  they  unfold  in  relation  one  to  another? 
How  do  they  get  free  from  the  sepals?  How  many  minutes  is  required 
for  the  whole  process  of  the  opening  of  the  flower?  How  many  flowers 
on  a plant  expand  during  the  same  evening?  Look  at  the  open  blossoms 
in  the  dark;  can  you  see  them?  How  do  they  look?  What  insects  do 
you  find  visiting  these  flowers? 

9.  How  long  does  the  primrose  blossom  remain  open?  How  do  the 
young  plants  of  the  evening  primrose  pass  the  winter?

THE  HEDGE  BINDWEED 
Teacher's  Story 

I once  saw  by  the  roadside  a beautiful 
pyramid,  covered  completely  with  green 
leaves  and  beset  with  pink  flowers.  I 
stopped  to  examine  this  bit  of  landscape 
gardening,  and  for  the  first  time  in  my  life 
I felt  sorry  for  a burdock;  for  this  burdock 
had  met  its  match  and  more  in  standing  up 
against  a weakling  plant  which  it  must  have 
scorned  at  first,  had  it  been  capable  of  this  sensa- 
tion. Its  mighty  leaves  had  withered,  its  flower- 
stems  showed  no  burs,  for  the  bindweed  had 
caught  it  in  its  hundred  embraces  and  had 
squeezed  the  life  out  of  it.  Once  in  Northern 
Florida  our  eyes  were  delighted  with  the  most 
beautiful  garden  we  had  ever  seen  and  which 
resolved  itself  later  into  a field  of  corn,  in  which 
every  plant  had  been  made  a trellis  for  the  bind- 
weed ; there  it  flaunted  its  pink  and  white  flowers 
in  the  sunshine  with  a grace  and  charm  that  sug- 
gested nothing  of  the  oppressor. 

Sometimes  the  bindweed  fails  to  find  support 
to  lift  it  into  the  air.  Then  it  quite  as  cheerfully 
mats  itself  oyer  the  grass,  making  a carpet  of 
exquisite  pattern.  This  vine  has  quite  an  effi- 
cient way  of  taking  hold.  . It  lifts  its  growing  tips 
into  the  air,  swaying  them  joyously  with  every 
breeze ; and  the  way  each  extreme  tip  is  bent  into 
d hook  seems  just  a matter  of  grace  and  beauty,  as  do  the  two  or  three 
loose  quirls  below  it ; when  during  its  graceful  swaying  the  hook  catches  to 
some  object,  it  makes  fast  with  amazing  rapidity;  later  the  young  arrow- 
shaped  leaves  manage  to  get  an  ear  over  the  support,  and  in  a very  short 
time  the  vine  makes  its  first  loop,  and  the  deed  is  done.  It  is  very  partic- 
ular to  twine  and  wind  in  one  way,  following  the  direction  of  the  hands 
of  the  clock — from  the  right,  under,  and  from  the  left,  over  the  object  to 
which  it  clings.  If  the  support  is  firm,  it  only  makes  enough  turns  around

it  to  hold  itself  firmly ; but  if  it  catches  to  something  as  unstable  as  its  own 
tendrils,  they  twist  until  so  hard-twisted  that  they  form  a support  in 
themselves. 

It  is  rather  difficult  to  perceive  the  alternate  arrangement  of  the  leaves 
on  the  bindweed  stem,  so  skillful  are  they  in  twisting  under  or  over  in 
order  to  spread  their  whole  graceful  length  and  breadth  to  the  sun ; to  the 
careless  observer  they  seem  only  to  grow  on  the  upper  or  outer  side  of  the 
vine.  The  leaves  are  arrow-shaped,  with  two  long,  backward,  and  out- 
ward projecting  points,  or  “ears,”  which  are  often  gracefully  lobed. 
Early  in  the  year  the  leaves  are  glossy  and  perfect ; bht  many  insects  love 
to  nibble  them,  so  that  by  September,  they  are  usually  riddled  with  holes. 

The  flower  bud  is  twisted  as  if  the  bindweed  were  so  in  the  habit  of 
twisting  that  it  carried  the  matter  farther  than  necessary.  Enveloping 
the  base  of  the  flower  bud  are  two  large  sepal-like  bracts,  each  keeled  like 
a duck’s  breast  down  the  center;  if  these  are  pulled  back,  it  is  seen  that 
they  are  not  part  of  the  flower,  because  they  join  the  stem  below  it.  There 
are  five  pale  green  sepals  of  unequal  sizes,  so  that  some  look  like  fragments 
of  sepals.  The  corolla  is  long,  bell-shaped,  opening  with  five,  starlike 
lobes;  each  lobe  has  a thickened  white  center;  and  while  its  margins  are 
usually  pink,  they  are  sometimes  a vivid  pink-purple  and  sometimes 
entirely  white.  Looking  down  into  this  flower-bell,  and  following  the 
way  pointed  out  by  the  white  star-points  which  hold  out  the  lobes,  we  find 
five  little  nectar- wells;  and  each  two  of  these  wells  are  separated  by  a 
stamen  which  is  joined  to  the  corolla  at  its  base  and  at  its  anther-end 
presses  close  about  the  style  of  the  pistil.  When  the  flower  first  opens,  it 
shows  the  spoon-shaped  stigmas  close  together,  pushing  up  through  the 
anther  cluster;  later,  the  style  elongates,  bringing  the  stigmas  far  beyond 
the  anthers.'  The  pollen  is  white,  and  through  the  lens  looks  like 
tiny  pearls. 

When  we  study  the  maturing  seed-capsule,  we  can  understand  the 
uneven  size  of  the  sepals  better;  for  after  the  corolla  with  the  attached 
stamens  falls,  the  sepals  close  up  around  the  pistil;  the  smallest  sepal 
wraps  it  first,  and  the  larger  ones  in  order  of  size,  enfolding  the  precious 
parcel;  and  outside  of  all,  the  great,  leafy  bracts  with  their  strong  keels 
provide  protection.  The  pod  has  two  cells  and  two  seeds  in  each  cell. 
But  it  is  not  by  seeds  alone  that  the  bindweed  spreads;  it  is  the  running 
rootstock  which,  when  the  plant  once  gets  a start,  helps  it  to  cover  a large 
area.  The  bindweed  is  a relative  of  the  morning-glory  and  it  will  prove 
an  interesting  study  to  compare  the  two  in  methods  of  twining,  in  the  time 
of  day  of  the  opening  of  the  flowers,  the  shape  of  the  leaves,  etc.  So  far 
as  my  own  observations  go,  the  bindweed  flowers  seem  to  remain  open 
only  during  the  middle  of  the  day,  but  Muller  says  the  flowers  stay  open 
on  moonlight  nights  to  invite  the  hawk-moths.  This  is  an  interesting 
question  for  investigation,  and  it  may  be  settled  by  a child  old  enough  to 
make  and  record  truthful  observations. 

There  are  several  species  of  bindweed,  but  all  agree  in  general  habits. 
The  field  bindweed  lacks  the  bracts  at  the  base  of  the  flower.

LESSON  CXXIX 
The  Hedge  Bindweed 

Leading  thought — There  are  some  plants  which  have  such  weak  stems 
that  they  are  obliged  to  cling  to  objects  for  support.  The  bindweed  is  one 
of  these,  and  the  way  that  it  takes  hold  of  objects  and  grows  upon  them 
is  an  interesting  story. 

Method — It  is  better  to  study  this  plant  where  it  grows ; but  if  this  is 
not  practical,  the  vine  with  its  support  should  be  brought  into  the  school- 
room, the  two  being  carefully  kept  in  their  natural  relative  positions. 
Several  of  the  questions  should  be  given  to  the  pupils  for  their  personal 
observation  upon  this  vine  in  the  field.  It  is  an  exoellent  study  for 
pencil  or  water-color  drawing. 

Observations — i.  How  does  the  bindweed  get  support,  so  that  its 
leaves  and  its  flowers  may  spread  out  in  the  sunshine  ? Why  does  its  own 
stem  not  support  it  ? What  would  happen  to  a plant  with  such  a weak 
stem,  if  it  did  not  twine  upon  other  objects? 

2.  How  does  it  climb  upon  other  plants?  Does  its  stem  always  wind 
or  twist  in  the  same  direction?  How  does  it  first  catch  hold  of  the  other 
plant?  If  the  supporting  object  is  firm,  does  it  wind  as  often  for  a given 
space  as  when  it  has  a frail  support?  Can  you  see  the  reason  for  this? 

3.  Look  at  the  leaves.  Sketch  one,  to  be  sure  that  you  see  its  beauti- 
ful form  and  veins.  Note  if  the  leaves  are  arranged  alternately  on  the 
stemi  and  then  observe  how  and  why  they  seem  to  come  from  one  side  of 
the  stem.  Why  do  they  do  this? 

4.  What  is  there  peculiar  about  the  flower  bud?  Look  at  its  stem 
carefully  and  describe  it.  Cut  it  across  and  look  at  the  end  with  a lens 
and  describe  it.  Turn  back  two  sepal-like  bracts  at  the  base  of  the  flower 
or  bud.  Are  they  a part  of  the  flower,  or  are  they  below  it?  Find  the 
true  sepals.  How  many  are  there?  Are  they  all  the  same  size ? 

5.  Examine  the  flower  in  blossom.  What  is  its  shape?  Describe  its 
colors.  Look  down  into  it.  How  many  stamens  are  there,  and  how  are 
they  set  in  the  flower?  How  does  the  pistil  look  when  the  flower  first 
opens?  Later?  Can  you  see  the  color  of  the  pollen?  Can  you  find 
where  the  nectar  is  borne?  How  many  nectar-wells  are  there? 

6.  What  insects  do  you  find  visiting  bindweed  flowers?  Do  the 
flowers  remain  open  at  night  or  on  dark  days? 

7.  Study  the  seed-capsule.  How  is  it  protected  on  the  outside? 
What  next  enfolds  it?  Can  you  see  now  the  uses  of  the  sepals  of  several 
sizes  ? Cut  a seed-capsule  across  with  all  its  coverings,  and  see  how  it  is 
protected.  How  many  seeds  are  there  in  the  capsule? 

8.  Has  the  bindweed  other  methods  of  spreading  than  by  seeds? 
Look  at  the  roots  and  tell  what  you  observe  about  them. 

9.  Make  a study  of  the  plant  on  which  the  bindweed  is  climbing,  and 
tell  what  has  happened  to  it. 

10.  Compare  the  bindweed  with  the  morning-glory,  and  notice  the 
differences  and  resemblances.

THE  DODDER 


Teacher's  Story 


If  Sinbad’s  “Old  Man  of  the 
Sea”  had  been  also  a sneak  thief, 
then  we  might  well  liken  him  to 
dodder.  There  is  an  opportu- 
nity for  an  excellent  moral  lesson 
connected  with  the  study  of  dod- 
der and  its  underhand  ways. 
When  a plant  ceases  to  be  self- 
supporting,  when  it  gets  its  own 
living  from  the  food  made  by 
other  plants  for  their  own  sus- 
tenance, it  loses  its  own  power  of 
food-making;  and  the  dodder  is 
an  excellent  example  of  the  in- 
evitable punishment  for  “spong- 
ing” a living.  The  dodder  has 
no  leaves  of  its  own  for  it  does 
not  need  to  manufacture  food 
nor  to  digest  it.  Its  dull  yellow 
stems  reach  out  in  long  tendrils, 
swayed  by  every  breeze,  until 
they  come  in  contact  with  some 
other  plant  to  which  they  at  once 
make  fast.  One  of  these  tendrils 
seizes  its  victim  plant  as  a serpent 
winds  its  prey,  except  that  it 
always  winds  in  the  same  direc- 
tion— it  passes  under  from  the 
right  side  and  over  from  the  left. 
Who  knows  whether  the  serpents 
are  always  so  methodical ! After 
dodder  gets  its  hold,  little  pro- 
jections appear  upon  its  coiled 
stems,  which  look  like  the  prolegs 
of  a caterpillar ; but  they  are  not 
legs,  they  are  suckers,  worse 
than  those  of  the  devil-fish;  for 
the  latter  uses  its  suckers  only  to 
hold  fast  its  prey;  but  the  dod- 
der uses  its  suckers  to  penetrate 
the  bark  of  its  victim,  and  reach 
down  to  the  sap  channels  where 
they  may,  vampirelike,  suck  the 
blood  from  their  victims,  or 
rather  the  matured  sap  which 
is  flowing  from  the  leaves  to 
the  growing  points  of  the  host 
plant.  Not  having  anything  else  to  do,  dodder  devotes  its  energies  to  the 
producing  of  seeds,  in  order  to  do  more  mischief.  The  species  which

attack  clover  and  other  farm  crops  seem  to  manage  to  get  their  seeds 
harvested  with  the  rest;  and  the  farmer  who  does  not  know  how  to  test 
his  clover  seed  for  impurities,  sows  with  it  the  seeds  of  its  enemy. 

The  dodder  flowers  are  small,  globular  and  crowded  together.  The 
calyx  has  five  lobes;  the  corolla  is  globular,  with  five  little  lobes  around 
its  margin  and  a stamen  set  in  each  notch.  A ew  of  the  species  have  a 
four-lobed  calyx  and  corolla;  but  however  many  the  lobes,  the  flowers  are 
shiftless  looking  and  are  yellowish  or  greenish  white ; despite  its  shiftless 
appearance,  however,  each  flower  manages  to  mature  four  perfectly  good, 
plump  seeds. 

There  are,  according  to  Gray,  nine  species  of  dodder  more  or  less 
common  in  America.  Some  of  the  species,  among  which  is  the  flax 
dodder,  live  only  upon  certain  other  species  of  plant  life,  while  others  take 
almost  anything  that  comes  within  reach.  Where  it  flourishes,  it  grows 
so  abundantly  that  it  makes  large  yellow  patches  in  fields,  completely 
choking  out  the  leaves  of  its  victims. 

LESSON  CXXX 
The  Dodder 

Leading  thought — There  are  some  plants  which  not  only  depend  upon 
other  plants  to  hold  them  up,  but  they  suck  the  life-juice  from  these  plants 
and  thus  they  steal  their  living. 

Method — Bring  in  dodder  with  the  host  plant  for  the  pupils  to  study  in 
the  schoolroom,  and  ask  them  to  observe  afterwards  the  deadly  work  of 
this  parasite  in  the  field. 

Observations — i.  What  is  the  color  of  the  stem?  In  which  direction 
does  it  wind? 

2 . How  is  the  stem  fastened  to  the  host  plant  ? Tear  off  these  suckers 
and  examine  the  place  where  they  were  attached  with  a lens,  and  note  if 
they  enter  into  the  stem  of  the  host  plant. 

3.  How  does  the  dodder  get  hold  of  its  victim?  Has  the  dodder  any 
leaves  of  its  own?  How  can  it  get  along  and  grow  without  leaves? 

4.  How  do  the  flowers  look  through  a lens?  Are  there  many  flowers? 
Can  you  see  the  petal  lobes  and  the  stamens? 

5.  How  many  seeds  does  each  flower  develop?  How  do  the  seeds 
look ? In  what  way  are  they  a danger  to, our  agriculture  ? 

I should  also  avoid  the  information  method.  It  does  a child  little  good  merely  to 
tell  him  matters  of  fact.  The  facts  are  not  central  to  him  and  he  must  retain  them 
by  a process  of  sheer  memory;  and  in  order  that  the  teacher  may  know  whether  he 
remembers , the  recitation  is  employed , — re-cite,  to  tell  over  again.  The  educational 
processes  of  my  younger  days  were  mostly  of  this  order, — the  book  or  the  teacher  told, 
I re-told,  but  the  results  were  always  modified  by  an  unpredictable  coefficient  of 
i< evaporation . Good  teachers  now  question  the  child  to  discover  what  he  has  found  out 
or  what  he  feels,  or  to  suggest  what  further  steps  may  be  taken , and  not  to  mark  him 
on  what  he  remembers.  In  other  words,  the  present-day  process  is  to  set  the  pupil 
independently  at  work,  whether  he  is  young  or  old,  and  the  information-leaflet  or 
lesson  does  not  do  this.  Of  course,  it  is  necessary  to  give  some  information,  but 
chiefly  for  the  purpose  of  putting  the  pupil  in  the  way  of  acquiring  for  himself  and 
to  answer  his  natural  inquiries;  but  information-giving  about  nature  subjects  is  not 
nature-study. — L.  H.  Bailey  in  “The  Outlook  to  Nature.”

THE  MILKWEED 
Teacher's  Story 

“ Little  weavers  of  the  summer,  with  sunbeam  shuttle  bright, 

And  loom  unseen  by  mortals,  you  are  busy  day  and  night, 
Weaving  fairy  threads  as  filmy,  and  soft  as  cloud  swans,  seen 
In  broad  blue  sky-land  rivers,  above  earth' s fields  of  green." 

— Ray  Laurance. 


(S  there  any  other  young  plant  that  shows  off  its 
baby-clothes  as  does  the  young  milkweed! 
When  it  comes  up  through  the  soil,  each  leaf  is 
folded  lengthwise  around  the  stem,  flannel 
side  out,  and  it  is  entirely  soft  and  white  and 
infantile.  The  most  striking  peculiarity  of 
the  milkweed  plant  is  its  white  juice,  which  is  a 
kind  of  rubber.  Let  a drop  of  it  dry  on  the 
back  of  the  hand,  and  when  we  try  to  remove 
it  we  find  it  quite  elastic  and  possessed  of  all 
of  the  qualities  of  crude  rubber.  At  the  first  trial  it  seems  quite  impossi- 
ble to  tell  from  which  part  of  the  stem  this  white  juice  comes,  but  by 
blotting  the  cut  end  once  or  twice,  the  hollow  of  the  center  of  the  stem  is 
seen  to  have  around  it  a dark  green  jring,  and  outside  this  is  a light  green 
ring.  It  is  from  the  dark  green  ring  encircling  the  stem  cavity  that  the 
milk  exudes.  This  milk 
is  not  the  sap  of  the  plant 
any  more  than  resin  is  the 
sap  of  the  pine;  it  is  a 
special  secretion,  and  is 
very  acrid  to  the  taste, 
rendering  milkweed  dis- 
gusting to  grazing  ani- 
mals. If  a milkweed 
stem  be  broken  or  gashed, 
this  juice  soon  heals  the 
wound  and  keeps  out 
germs,  and  thus  is  of  great 
use  to  the  plant,  since 
many  insects  feed  upon  it. 

If  cut  across,  every  vein 
in  every  leaf  produces 
“milk”,  and  so  does  every 
small  flower  pedicel. 

When  the  “milk”  is  by 
chance  smeared  on  cloth 
and  allowed  to  dry,  soap 
and  water  will  not  remove 
it,  but  it  yields  readily  to 
chloroform,  which  is  a sol- 
vent of  rubber.

pairs;  if  one  pair  points  east  and  west,  the  pair  above  and  the  pair 
below  point  north  and  south.  The  leaf  is  beautiful  in  every  particular; 
it  has  a dark  green  upper  surface,  diversified  with  veins  that  join  in 
scallops  near  the  border;  it  is  soft  to  the  touch  on  the  upper  surface, 
and  is  velvety  below.  The  lens  reveals  that  the  white  under  surface, 
or  the  nap  of  the  velvet,  is  a cover  of  fine  white  hairs. 

The  flower  of  the  milkweed  is  too  complicated  for  little  folks  even  to 
try  to  understand ; but  for  the  pupils  of  the  seventh  and  eighth  grades 
it  will  prove  an  interesting  subject  for  investigation,  if  they  study  it 
with  the  help  of  a lens.  In  examining  the  globular  bud,  we  see  the  five 
hairy  sepals,  which  are  later  hidden  by  the  five  long,  pinkish  green  petals 
which  bend  back  around  the  stem.  When  we  look  into  the  flower,  we 
see  five  little  cornucopias — which  are  really  horns  of  plenty,  since 
they  are  filled  with  nectar;  from  the  center  of  each  is  a little,  fleshy 
tongue,  with  its  curved  point  resting  on  the  disk  at  the  center  of  the 
flower.  Between  each  two  of  these  nectar-horns  can  be  seen  the 
white  bordered  opening  of  a long  pocket — like  a dress-pocket — at 
the  upper  end  of  the  opening  of  which  is  a black  dot.  Slip  a needle  into 
the  pocket  opening  until  it  pushes  against  the  black  dot,  and  out  pops  a 
pair  of  yellow  saddle-bags,  each  attached  to  the  black  dot  which  joins 
them.  These  are  the  pollen-bags,  and  each  was  borne  in  a sac,  shaped 
like  a vest-pocket,  one  lying  either  side  of  the  upper  end  of  the  long 
pocket.  These  pollen-bags  are  sticky,  and  they  contract  so  as  to  close 
over  the  feet  of  the  visiting  bee.

Since  the  stem  of  the  flower  cluster  droops 
and  each  flower  pedicel  droops,  the  bee  is 
obliged  to  cling,  hanging  back  down,  while  get- 
ting the  nectar,  and  has  to  turn  about  as  if  on  a 
pivot  in  order  to  thrust  her  tongue  into  the  five 
cornucopias  in  succession ; she  is  then  certain  to 
thrust  her  claws  into  a long  pocket,  and 
it  proceeds  to  close  upon  them,  its  edges 
being  like  the  jaws  of  a trap.  The  bee,  in 
trying  to  extricate  her  feet,  leaves  whatever 
pollen-bags  she  had  inadvertently  gathered 
in  this  trap-pocket,  which  gives  them  pass- 
age to  the  stigma.  But  the  milkweed  flower, 
like  some  folks,  is  likely  to  overdo  matters,  and 
sometimes  these  pockets  grasp  too  firmly  the 
legs  of  the  bee  and  hold  her  a prisoner.  We  often 
find  insects  thus  caught  and  dead — a result  as 
far  from  the  plan  of  the  flower  as  from  that  of  the 
insect  victim,  had  both  been  conscious.  Some- 
times bees  become  so  covered  with  these  pollen- 
bags,  which  they  are  unable  to  scrape  off,  that 
they  die  because  of  the  clogging.  But  for  one 
bee  that  suffers  there  are  thousands  that  carry 
off  the  nectar  triumphantly,  just  as  thousands  of 
people  travel  by  water  for  one  that  is  drowned. 

The  milkweed  pod  has  been  the  admiration  of 
nature  students  from  the  beginning,  and  surely 
there  is  no  plant  structure  that  so  interests  the

child  as  this  house  in  which  the  milkweed  carries  its  seeds.  When  we 
look  at  a green  pod,  we  first  admire  its  beautiful  shape;  on  -either  side 
of  the  seam,  which  will  sometime  open,  are  three  or  four  rows  of 
projecting  points  rising  from  the  felty  surface  of  the  pod  in  a way 
that  suggests  embossed  embroidery.  We  open  the  pod  by  pulling 
it  apart  along  the  seam;  and  this  is  not  a seam  with  a raw  edge  but  is 
finished  with  a most  perfect  selvage.  When  we  were  children  we  were 
wont  to  dispossess  these  large  green  pods  of  their  natural  contents,  and 
because  they  snapped  shut  so  easily,  we  imprisoned  therein  bumblebees 
“to  hear  them  sing,”  but  we  always  let  them  go  again.  We  now  know 
that  there  is  nothing  so  interesting  as  to  study  the  contents  of  the  pod 
just  as  it  is.  Below  the  opening  is  a line  of  white  velvet ; at  one  end,  and 
with  their  “heads  all  in  one  direction,”  are  the  beautiful,  pale-rimmed, 
brown,  overlapping  seeds;  and  at  the  other  end  we  see  the  exquisite 
milkweed  silk  with  the  skein  so  polished  that  no  human  reel  could  give  us 
a skein  of  such  luster.  If  we  remove  the  contents  of  the  pod  as  a whole, 
we  see  that  the  velvety  portion  is  really  the  seed-support  and  that  it  joins 
the  pod  at  either  end.  It  is  like  a hammock  full  of  babies,  except  that  the 
milkweed  babies  are  fastened  on  the  outside  of  the  hammock. 

No  sooner  is  our  treasure  open  to  the  air  than  the  shining  silk  begins  to 
separate  into  floss  of  fairy  texture.  But  before  one  seed  comes  off,  let  us 
look  at  the  beautiful  pattern  formed  by  the  seeds  overlapping — such  pat- 
terns we  may  see  in  the  mosaics  of  mosques. 

Pull  off  a seed,  and  with  it  comes  its  own  skein  of  floss,  shining  like  a 
pearl;  but  if  we  hold  the  seed  in  the  hand  a moment  the  skein  unwinds 
itself  into  a fluff  of  shining  threads  as  fine  as  spiders’  silk,  and  each 
individual  thread  thrusts  itself  out  and  rests  upon  the  air:  and  altogether 
there  are  enough  of  the  threads  to  float  the  seed,  a balloon  of  the  safest 
sort.  If  we  wreck  the  balloon  by  rubbing  the  floss  through  our  fingers, 
we  shall  feel  the  very  softest  textile  fiber  spun  by  Mother  Nature. 

If  we  look  closely  at  our  seed  we  see  a margin  all  around  it.  Well, 
what  if  the  balloon  should  be  driven  over  sea,  and  the  seed  dropped  upon 
the  water  ? It  must  then  drown  unless  it  has  a life  preserver ; this  margin 
that  we  have  noted  is  of  the  safest  cork,  and  is  warranted  to  float ; if  you 
do  not  believe  it,  try  it. 

If  we  pull  off  all  the  seeds,  we  can  see  that  the  velvety  support  is  flat 
and  that  all  of  the  seeds  are  attached  to  it,  but  before  we  stop  our  admir- 
ing study  we  should  look  carefully  again  at  the  inside  of  the  pod,  for  never 
was  there  a seed  cradle  with  a lining  more  soft  and  satiny. 

LESSON  CXXXI 
The  Milkweed 

Leading  thought — The  milkweed  when  wounded  secretes  a milky  juice 
which  is  of  a rubberlike  composition ; it  flows  out  of  the  wounded  plant 
and  soon  hardens,  thus  protecting  the  wound  from  germs.  Milkweed 
flowers  depend  entirely  upon  insects  for  pollenation ; the  pollen  is  not  a . 
free,  yellow  powder,  but  it  is  contained  in  paired  sacs,  which,  are  joined 
in  V-shape.  The  seeds  are  carried  by  balloons,  and  they  can  float  on 
water  as  well. 

Method — Begin  the  study  of  the  plant  when  it  first  appears  above 
ground  in  April  or  May.  Give  the  pupils  the  questions  about  the  blossom 


Milkweed  seed-balloons  just  leaving  the  sheltering  pod.

Handbook  of  Nature-Study 


for  a vacation  study,  and  ask  that  their  observations  be  kept  in  their  note- 
books. The  study  of  the  pods  and  seeds  may  be  made  in  September  or 
October.  When  studying  the  milky  juice,  add  a geography  lesson  on 
rubber  trees  and  the  way  that  rubber  is  made. 

Observations — i.  The  plant.  How  does  the  milkweed  look  as  it  ap- 
pears above  ground  in  the  spring?  How  are  its  leaves  folded  when  it  first 
puts  its  head  up  ? Cut  off  a fully  expanded  plant  a few  inches  above  the 
ground.  What  flows  out  of  the  stem?  Blot  off  the  “milk”  and  study 
the  cross-section  of  the  stem.  What  is  at  the  center?  How  many  layers 
do  you  see  around  this  center?  Can  you  see  from  which  the  milkweed 
juice  comes?  How  does  the  juice  feel  as  it  dries  on  your  fingers?  How 
does  it  look  when  dry?  Place  a few  drops  on  a piece  of  paper  and  when 
it  is  dry  pull  it  off  and  see  if  it  is  elastic.  Break  the  edge  of  the  leaf. 
Does  the  milky  juice  flow  from  it?.  Does  it  come  from  the  veins?  Do 
you  think  that  this  is  the  sap  of  the  milkweed?  Cut  a gash  in  the  milk- 
weed stem  and  see  how  the  “milk”  fills  the  wound.  How  does  this  help 
the  plant?  Do  cattle  feed  upon  the  milkweed  when  it  grows  in  pastures? 
If  not,  why? 

2.  How  are  the  leaves  arranged  on  the  stem?  How  do  the  upper  and 
under  sides  of  the  leaves  differ  ? Examine  with  a lens,  and  see  what  makes 
the  nap  of  the  velvet.  What  gives  the  light  color  to  the  under  side? 
Sketch  a leaf  showing  its  shape  and  venation,  noting  especially  the 
direction  of  the  veins  as  they  approach  the  edge  of  the  leaf. 

3.  The  flower.  Where  do  the  flower  clusters  come  off  the  stems  in 
relation  to  the  leaves?  Does  the  stem  of  the  flower  cluster  stand  stiff  or 
droop?  Take  a good  sized  flower  cluster  and  count  the  flowers  in  it. 
What  would  happen  if  all  these  flowers  should  develop  into  pods?  How 
many  flower  clusters  do  you  find  on  one  plant?  Which  of  these  clusters 
open  first?  Last? 

4.  Take  off  a single  bud  with  its  stem,  or  pedicel.  Does  the  milky 
juice  come  at  the  break?  Is  the  bud  stem  stiff  or  drooping?  What  is  its 
color  and  how  does  it  feel?  What  is  the  shape  of  the  bud?  How  many 
sepals  has  it?  Look  at  the  stem,  sepals  and  bud  with  a lens  and  describe 
their  covering.  Look  for  a flower  just  opening  where  the  petals  stand  out 
around  it  like  a five-pointed  star.  What  is  their  color?  What  happens 
to  the  petals  when  the  flower  is  fully  expanded  ? Can  you  see  the  sepals 
then?  Look  straight  into  the  flower.  Do  you  see  the  five  nectar-horns? 
Look  at  them  with  a lens  and  describe  them.  What  do  you  suppose  is  the 
use  of  the  little  curved  tongue  coming  out  of  each?  Where  does  the  tip 
of  the  tongue  rest?  With  a lens,  look  between  two  of  the  nectar  horns; 
can  you  see  a little  slit  or  pocket,  with  white  protruding  edges  ? Note  just 
above  the  pocket  a black  dot;  thrust  a needle  into  this  pocket  near  its 
base  and  lift  it  toward  the  crown  of  the  flower,  touching  the  black  dot. 
What  happens? 

5 . Describe  the  little  branched  ob  j ect  that  came  out  when  you  touched 
it  with  a needle.  These  are  the  pollen  saddle-bags  and  each  bag  comes 
from  a pocket  at  one  side  of,  and  above  the  long  pocket.  Do  these  saddle- 
bags cling  to  the  needle?  Look  with  a lens  at  some  of  the  older  flowers, 
and  see  if  you  can  find  the  pollen-bags  protruding'  from  the  long  pocket. 
See  if  you  can  find  how  the  long  pocket  is  a passageway  to  the  stigma. 
To  see  how  the  little  saddle-bags  were  transported,  watch  a bee  gathering 
nectar.  Describe  what  happens. 


Wild-Flower  Study

6.  Since  the  flowers  bend  over,  how  must  the  bee  hold  on  to  the 
flower  while  she  gathers  nectar  from  the  horns?  As  she  turns  around, 
would  she  naturally  pull  out  some  of  the  saddle-bags  ? Catch  a bee  in  a 
collecting  tube  and  see  if  her  feet  have  upon  them  these  pollen-sacs. 
After  gathering  these  pollen-sacs  upon  her  feet,  what  happens  to  them 
when  she  visits  the  next  flower?  Is  the  opening  of  the  long  pocket  like  a 
trap  to  scrape  the  sacs  off  ? Can  you  find  on  milkweed  flowers  any  bees  or 
other  insects  that  have  been  entangled  in  these  little  traps  and  have  thus 
perished?  Try  the  experiment  of  drawing  a thread  into  one  of  these 
traps  and  with  your  lens  see  if  the  opening  closes  over  it. 

7.  How  many  kinds  of  insects  do  you  find  visiting  the  milkweed 
flowers?  Can  you  detect  the  strong  odor  of  the  flowers?  Why  must  the 
milkweed  develop  so  many  flowers  and  offer  such  an  abundance  of  nectar?

THE  WHITE  WATER  LILY 
Teacher's  Story 

“Whence  O fragrant  form  of  light, 

Hast  thou  drifted  through  the  night 
Swanlike,  to  a leafy  nest, 

On  the  restless  waves  at  rest." 

Thus  asks  Father  Tabb,  and  if  the  lily  could  answer  it  would  have  to 
say:  “Through  ages  untold  have  the  waves  upheld  me  until  my  leaves 

and  my  flowers  have  changed  into  boats,  my  root  to  an  anchor,  and  my 
stems  to  anchor-ropes.” 

There  is  no  better  example  for  teaching  the  relation  between  geogra- 
phy and  plant  life  than  the  water  lily.  Here  is  a plant  that  has  dwelt  so 
long  in  a certain  situation  that  it  cannot  live  elsewhere.  The  conditions 
which  it  demands  are  quiet  water,  not  too  deep,  and  with  silt  bottom. 
Every  part  of  the  plant  relies  upon  these  conditions.  The  rootstock  has 
but  few  root  hairs;  and  it  lies  buried  in  the  silt,  not  only  because  this 
gives  it  food,  but  because  it  can  there  act  as  an  anchor.  Rising  from  the 
rootstock  is  a stem  as  pliable  as  if  made  of  rubber,  and  yet  it  is  strong; 


546 


Handbook  of  N ature-Study 


its  strength  and  flexibility  are  gained  by  having  at  its  center  four  hollow 
tubular  channels,  and  smaller  channels  near  the  outside.  These  tubes 
extend  the  whole  length  of  the  stem,  making  it  light  so  that  it  will  float, 
and  at  the  same  time  giving  it  strength  as  well  as  flexibility.  At  the 
upper  end  of  the  stem  is  a leaf  or  flower,  which  is  fashioned  as  a boat. 
The  circular  leaf  is  leathery  and  often  bronze-red  below,  with  prominent 
veins,  making  an  excellent  bottom  to  the  boat;  above,  it  is  green  with  a 
polished  surface,  and  here  are  situated  its  breathing-pores,  although  the 
leaves  of  most  plants  have  these  stomata  in  the  lower  surface.  But  how 
could  the  water  lily  leaf  breathe,  if  its  stomata  opened  in  the  water?  The 
leaf  is  large,  circular  and  quite  heavy;  it  would  require  a very  strong,  stiff 
stem  to  hold  it  aloft,  but  by  its  form  and  structure  it  is  fitted  to  float  upon 
the  water,  a little  green  dory,  varnished  inside,  and  waterproof  outside. 

The  bud  is  a little,  egg-shaped  buoy  protected  by  its  four  pinkish 
brown,  leathery  sepals;  as  it  opens,  we  can  see  four  rows  of  petals,  each 
overlapping  the  space  between  the  next  inner  ones;  at  the  center  there  is 
a fine  display  of  brilliant  yellow  anthers.  Those  hanging  over  the  green- 
ish yellow  pit,  which  has  the  stigma  at  its  center,  are  merely  golden  hooks. 

When  the  flower  is  quite  open,  the 
four  sepals,  each  a canoe  in  form,  lie 
under  the  lily  and  float  it;  although 
the  sepals  are  brownish  outside,  they 
are  soft  white  on  the  inside  next  the 
flower.  Between  each  two  sepals 
stands  a large  petal,  also  canoe-shaped, 
and  perhaps  pinkish  on  the  outside; 
these  help  the  sepals  in  floating  the 
flower.  Inside  of  these  there  is  a row 
of  large  creamy  white  petals  which 
stand  upright ; the  succeeding  rows  of 
petals  are  smaller  toward  the  center 
and  grade  into  the  outer  rows  of 
stamens,  which  are  petallike  at  the 
base  and  pointed  at  the  tip.  The 
inner  rows  of  stamens  make  a fine 
golden  fringe  around  the  cup-shaped  pistil.  This  flower  is  of  great  use  in 
teaching  that  sepals,  petals  and  stamens  have  the  same  origin  and  grade 
into  each  other,  showing  the  intermediate  stages. 

It  has  been  stated  that  pond  lilies,  in  the  state  of  nature,  have  an 
interesting  way  of  opening  in  the  early  morning,  closing  at  noon  and 
opening  again  toward  evening.  If  we  knew  better  the  habits  of  the 
insects  which  pollenate  these  flowers,  we  should  possibly  have  the  key  to 
this  action.  In  our  ponds  in  parks  and  grounds  we  find  that  each  species 
of  pond  lily  opens  and  closes  at  its  own  particular  time  each  day.  Each 
flower  opens  usually  for  several  consecutive  days,  and  the  first  day  of  its 
blooming  it  opens  about  an  hour  later  and  closes  an  hour  earlier  than  on 
the  days  following.  After  the  lilies  have  blossomed,  the  flower  stem  coils 
in  a spiral  and  brings  the  ripening  seeds  below  the  surface  of  the  water. 
The  reason  for  this  has  not  yet  been  discovered.  After  about  two  months 
the  pod  bursts  letting  the  seeds  out  in  the  water.  Each  seed  is  in  a little 
bag,  which  the  botanists  call  an  aril,  and  which  serves  as  a life  preserver 
floating  the  seed  off  for  some  distance  from  the  parent  plant.  The  aril

finally  decays  and  the  seed  falls  to  the  bottom  where,  if  the  conditions  are 
favorable,  it  develops  into  a new  plant. 

To  emphasize  the  fact  that  the  water  lily  is  dependent  upon  certain 
geographical  conditions,  ask  the  pupils  to  imagine  a water  lily  planted 
upon  a hillside.  How  could  its  roots,  furnished 
with  such  insufficient  rootlets,  get  nourishment 
there  ? How  could  its  soft,  flexible  stems  hold  aloft 
the  heavy  leaves  and  blossoms  to  the  sunlight?  In 
such  a situation  it  would  be  a mere  drooping  mass. 
Moreover,  if  the  pupils  understand  the  conditions 
in  which  the  water  lilies  grow  in  their  own  neighbor- 
hood, they  can  understand  the  conditions  under 
which  the  plant  grows  in  other  countries.  Thus, 
when  they  read  about  the  great  Victoria  regia  of  the 
Amazon, — that  water  lily  whose  leaves  are  large 
enough  to  support  s man, — they  would  have  visions 
of  broad  stretches  of  still  water  and  they  should 
realize  that  the  bottom  must  be  silt.  If  they  read 
about  the  lotus,  of  Egypt,  then  they  should  see  the 
Nile  as  a river  with  borders  of  still  water  and  with 
bottom  of  silt.  Thus,  from  the  conditions  near  at 
hand,  we  may  cultivate  in  the  child  an  intelligent 
geographical  imagination. 

LESSON  CXXXII 
The  Water  Lily 

Leading  thought — The  water  lily  has  become  dependent  upon  certain 
conditions  in  pond  or  stream,  and  has  become  unfitted  in  form  to  live 
elsewhere.  It  must  have  quiet  waters,  not  too  deep,  and  with  silt  bottom. 

Method — The  study  should  be  made  first  with  the  water  lilies  in  a 
stream  or  pond,  to  discover  just  how  they  grow.  For  the  special  struc- 
ture, the  leaves  and  flowers  may  be  brought  to  the  schoolroom  and  floated 
in  a pan  of  water.  The  lesson  may  easily  be  modified  to  fit  the  yellow 
water  lily,  which  is  in  many  ways  even  more  interesting,  since  in  shallow 
water  it  holds  its  leaves  erect  while  in  deeper  water  its  leaves  float. 

Observations — i.  Where  is  the  water  lily  found?  If  in  a pond,  how 
deep  is  the  water?  If  in  a stream,  is  it  in  the  current?  What  kind  of 
bottom  is  there  to  the  stream  or  pond  ? Do  you  find  lilies  in  the  water  of 
a limestone  region  ? Why  ? 

2 . What  is  the  shape  of  the  leaf  ? What  is  the  color  above  and  below ? 
What  is  the  texture?  How  is  it  especially  fitted  to  float?  How  does  it 
look  when  very  young? 

3.  Examine  the  petiole.  How  long  is  it?  Is  it  stiff  enough  to  hold 
up  the  leaf?  Why  does  it  not  need  to  hold  up  the  leaf?  How  does  it 
serve  as  an  anchor?  Cut  a stem  across  and  describe  its  inside  structure. 
How  does  this  structure  help  it  float? 

4.  Examine  the  open  flower.  How  many  sepals?  How  many  rows 
of  petals?  How  do  the  stamens  resemble  the  petals?  Can  you  see  in  the 
water  lily  how  the  sepals,  petals  and  stamens  may  all  be  different  forms  of 
the  same  thing?  How  are  the  sepals  fitted  to  keep  the  flower  afloat?  At 
what  times  of  the  day  does  the  lily  open?  At  what  hours  does  it  close?

Handbook  of  N ature-Study 


5.  Describe  the  pistil.  When  the  lily  first  opens,  how  are  the  stamens 
placed  around  the  pis  Lil?  What  happens  to  the  seed-box  after  the  blos- 
soms have  faded?  Does  the  seed-pod  float  upon  the  water  as  did  the 
flower?  What  sort  of  stem  has  the  flower?  How  does  this  stem  hold  the 
seed-pod  below  the  water? 

6.  What  sort  of  seed  has  the  water  lily?  Sketch  the  seed-pod. 
How  does  the  seed  escape  from  it  ? How  is  it  scattered  and  planted  ? 

7.  What  sort  of  a root  has  the  water  lily  ? Are  there  many  fine  root- 
lets upon  it ? Why?  How  does  this  rootstock  serve  the  plant  aside  from 
gettingfood? 

8.  Imagine  a water  lily  set  on  a dry  hillside.  Could  the  stems  uphold 
the  flowers  or  leaves?  Is  the  petiole  large  enough  to  hold  out  such  a 
thick,  heavy  leaf?  Could  the  root  get  food  from  a dry  location?  Why? 

9.  Judging  from  what  you  know  of  the  places  where  water  lilies  grow 
and  the  condition  of  the  water  there,  describe  the  Nile  where  the  lotus 
grows.  Describe  the  Amazon  where  the  Victoria  regia  grows. 


PONDWEED 
Teacher's  Story 

HE  study  of  any  plant  which  has 
obvious  limitations  as  to  where  it 
may  grow  should  be  made  a help  in 
the  study  of  geography.  Pond- 
weed  is  an  excellent  subject  to  illus- 
trate this  principle ; it  grows  only  in 
quiet  beds  of  sluggish  streams  or  in 
ponds,  or  in  the  shallow  protected 
portions  of  lakes.  It  has  tremen- 
dous powers  of  stretching  up,  which 
render  it  able  to  grow  at  greater, 
depth  than  one  would  suppose  possi- 
ble, often  flourishing  where  the 
water  is  from  ten  to  twenty  feet 
deep.  Often,  when  the  sun  is  shin- 
ing, it  may  be  seen  like  a bed  of  sea- 
weed on  the  bottom.  Its  roots, 
like  those  of  most  water  plants,  have 
less  to  do  with  the  matter  of  absorb- 
ing water  and  nourishment  than  do 
the  roots  of  land  plants,  one  of  their 
chief  functions  being  to  anchor  the 
plant  fast;  they  have  a firm  grip  on 
the  bottom ; and  if  pondweed  is  cut  loose,  it  at  once  comes  to  the  sur- 
face, floats  helplessly  on  its  side,  and  soon  dies. 

The  stem  is  very  soft  and  pliable  and  the  plant  relies  entirely  on  the 
water  to  keep  it  upright.  A cross-section  of  the  stem  shows  that  its  sub- 
stance is  spongy,  with  the  larger  open  cells  near  the  outer  edge,  thus  help- 
ing it  to  float.  The  leaves  are  two  or  three  inches  long,  their  broad  bases 
encircling  the  stem,  their  tips  tapering  to  slender  points.  They  have 


Wild-Flower  Study 


549 


parallel  veins  and  ruffled  edges.  They  are  dull  olive  green  in  color,  much 
darker  than  the  stems;  in  texture  they  are  very  thin,  papery,  and  so 
shining  as  to  give  the  impression  of  being  varnished.  No  land  plants  have 
such  leaves;  they  remind  us  at  once  of  kelp  or  other  seaweeds.  The 
leaves  are  scattered  along  the  stems,  by  no  means  thickly,  for  water 
plants  do  not  seem  to  need  profuse  foliage. 

In  blossom  time  the  pondweed  shows  its  real  beauty.  The  stems  grow 
and  grow,  like  Jack’s  bean  stalk,  and  what  was  a bed  of  leaves  on  the  pond 
bottom  suddenly  changes  into  a forest  of  high  plants,  each  one  standing 
tall  and  straight  and  with  every  leaf  extended,  as  if  its  stems  wbre  as 
strong  and  stiff  as  ironwood ; but  if  a wave  disturbs  the  water  the  graceful 
undulations  of  the  plant  tell  the  true  story  of  the  pliant  stems.  There  is 
something  that  arouses  our  admiration  when  we  see  one  of  these  pond- 
weeds  grown  so  straight  and  tall,  often  three  or  four  yards  high,  in  order 
to  place  its  little,  greenish-brown  flower-head  above  the  water’s  surface. 

We  have  spent  hours  looking  down  into  such  a 
submerged  forest,  dreaming  and  wondering  about 
the  real  meaning  of  such  adaptations. 

Although  the  stem  is  flexible,  the  somewhat 
curved,  enlarged  portion  of  it  just  below  the  flower- 
head  is  rigid ; it  is  also  more  spongy  than  the  lower 
part  of  the  stem  and  is  thus  fitted  to  float  the  flower. 
The  flower  itself  is  one  of  the  prettiest  sights  that 
nature  has  to  show  us  through  a lens.  It  is  a Mal- 
tese cross,  the  four  reddish  stigmas  arranged  in  a 
solid  square  at  the  center ; at  each  side  of  this  cen- 
tral square  is  a double-barrelled  anther,  and  outside 
of  each  anther  is  a queer,  little,  dipper-shaped,  green 
sepal.  When  the  anthers  open,  they  push  away 
i , Flower  of  a pond-  f rom  the  stigmas  and  throw  their  pollen  toward  the 
weed  enlarged,  early  stage,  outside.  There  may  be  thirty  or  more  of  these 
2,  Same  at  later  stage.  tiny,  cross-shaped  flowers  in  one  flower-head.  In 
the  bud,  the  cup-shaped  sepals  shut  down  closely,  exposing  the  stigmas 
first,  which  would  indicate  that  the}-'  ripen  before  the  pollen  is  shed.  The 
pollen  is  white,  and  is  floated  from  plant  to  plant  on  the  surface  of  the 
water;  often  the  water  for  yards  will  be  covered  with  this  living  dust. 


LESSON  CXXXIII 
Pondweed 

Leading  thought — The  pondweed  lives  entirely  below  the  water;  at 
blossom  time,  however,  it  sends  up  its  flower  stems  to  the  surface  of  the 
water,  and  there  sheds  its  pollen,  thus  securing  cross-pollenation. 

Method — As  this  is  primarily  a lesson  that  relates  to  geography,  the 
pondweed  should  be  studied  where  it  is  growing.  It  may  be  studied  in 
the  spring  or  fall,  and  the  pupils  asked  to  observe  the  blossoming  which 
occurs  in  late  July.  After  the  pupils  have  seen  where  it  grows,  the  plants 
themselves  may  be  studied  in  an  aquarium,  or  by  placing  them  in  a pail  or 
basin  of  water.  There  are  confusing  numbers  of  pondweeds  but  any  of 
them  will  do  for  this  lesson.  The  one  described  in  the  Teacher’s  Story  is 
probably  P.  perfoliatus.

Observations — i.  Where  is  the  pondweed  found?  Does  it  ever 
grow  out  of  water ? Does  it  ever  grow  in  very  deep  water?  Does  it  ever 
grow  in  swiftly  flowing  water? 

2.  Has  the  pondweed  a root?  Does  the  pondweed  need  to  have 
water  carried  to  its  leaves,  as  it  would  if  it  were  living  in  the  air?  What  is 
-ne  of  the  chief  uses  of  the  roots  to  the  pondweed?  Break  off  a plant, 
does  it  float?  Do  you  think  it  would  float  off  and  die,  if  it  was  not 
anchored  by  its  root? 

3 . Compare  the  stem  of  pondweed  with  that  of  any  land  plant  stand- 
ing straight.  What  is  the  chief  difference  ? Why  does  the  pondweed  not 
need  a stiff  stem  to  hold  it  up?  Cut  the  stem  across,  and  see  if  you  can 
observe  why  it  floats? 

4.  Examine  the  leaves.  Are  all  of  them  below  the  surface  of  the 
water?  If  some  float,  how  do  they  differ  in  texture  and  form  from  those 
submerged?  How  are  they  arranged  on  the  stem?  Are  they  set  close 
together?  What  is  the  difference  in  texture  between  its  leaves  and  those 
of  the  jewelweed,  dock  or  any  other  land  plant?  If  any  leaves  project 
out  of  the  water  are  they  different  in  form  and  texture  from  those  sub- 
merged? Sketch  the  leaf,  showing  its  shape,  its  edges,  and  the  way  it 
joins  the  stem. 

5.  How  far  below  the  surface  of  the  water  does  the  pondweed  usually 
lie  ? Does  it  ever  rise  up  to  the  water’s  surface  ? When  ? Have  you  ever 
noticed  the  pondweed  in  blossom?  How  does  the  blossom  look  on  the 
water?  Can  you  see  the  white  pollen  floating  on  the  surface  of  the  water? 
Look  down  into  the  water  and  see  the  way  the  pondweed  stands  in  order 
to  float  its  blossoms. 

6.  Study  the  blossom.  Note  the  stem  that  bears  it.  Is  the  part  that 
bears  the  flower  enlarged  and  stiff er  than  the  stem  below?  Do  you  think 
that  this  enlarged  part  of  the  stem  acts  like  the  bob  on  a fish-line?  Ex- 
amine a flower  cluster  with  a lens.  How  many  flowers  upon  it?  Study 
one  flower  carefully.  Describe  the  four  stigmas  at  the  center.  Describe 
the  anthers  arranged  around  them.  Describe  the  sepal  which  protects 
each  anther.  When  the  anthers  open  do  they  discharge  the  pollen  toward 
or  away  from  the  stigmas  ? 

7.  What  happens  after  the  flowers  are  pollenated?  Do  they  still 
float?  What  sort  of  seed-capsule  has  the  pondweed?  Do  the  seeds 
break  away  and  float 

“ Again  the  wild  cow-lily  floats 
Her  golden-freighted,  tented  boats. 

In  thy  cool  caves  of  softened  gloom, 

O'  er  shadowed  by  the  whispering  reed. 

And  purple  plumes  of  pickerel  weed, 

And  meadow-sweet  in  tangled  bloom. 

“The  startled  minnows  dart  in  flocks, 

Beneath  thy  glimmering  amber  rocks. 

If  but  a zephyr  stirs  the  brake; 

The  silent  swallow  swoops,  a flash 
Of  light,  and  leaves  with  dainty  plash, 

A ring  of  ripples  in  her  wake."

THE  CAT-TAIL 

Teacher's  Story 

In  June  and  early  July,  if  the  cat -tail  be  closely  observed,  it  will  be 
seen  to  have  the  upper  half  of  the  cat’s  tail  much  narrower  and  different 
in  shape  from  the  lower  half— as  if  it  were  covered  with  a quite  different 
fur.  It  seems  to  be  clothed  with  a fine  drooping  fringe  of  olive-yellow. 
With  the  aid  of  a lens,  we  can  see  that  this  fringe  is  a mass  of  crowded 
anthers,  two  or  three  of  them  being  attached  to  the  same  stalk  by  a short 
filament.  These  anthers  are  packed  full  of  pollen,  which  is  sifted  down 
upon  the  pistillate  flowers  below  by  every  breeze ; and  with  every  puff  of 
stronger  wind,  the  pollen  is  showered  over  all  neighboring 
flowers  to  the  leeward.  There  is  not  much  use  in  trying 
to  find  the  pistillate  flowers  in  the  plush  of  the  cat-tail. 
They  have  no  sepals  nor  petals,  and  are  so  imbedded  in 
the  thick  pappus  which  forms  the  plush  that  the  search 
is  hardly  worth  while  for  nature-study,  unless  a micro- 
scope is  used.  The  ovary  is  rather  long,  the  style  slender, 
and  the  stigma  reaches  out  to  the  cut-plush  surface  of  the 
cat-tail.  The  pupils  can  find  what  these  flowers  are  by 
studying  the  seed;  in  fact,  the  seed  does  not  differ  very 
much  from  the  flower,  except  that  it  is  mature  and  is 
* browner  in  color. 

It  is  an  interesting  process  to  take  apart  a cat-tail  plant ; the  lower, 
shorter  leaves  surround  the  base  of  the  plant,  giving  it  size  and  strength. 
All  the  leaves  have  the  same  general  shape,  but  vary  in  length.  Each  leaf 
consists  of  the  free  portion,  which  is  long  and  narrow  and  flat  towards  its 
tapering  tip  but  is  bent  into  a trough  as  it  nears  the  plant,  and  the  lower

portion  of  the  leaf,  which  clasps  the  plant  entirely  or  partially,  depending 
upon  whether  it  is  an  outer  or  inner  leaf,  and  thus  adds  to  its  strength. 
We  almost  feel  as  if  these  alternate  leaves  were  consciously  doing  their 
best  to  protect  the  slender,  flower  stem.  The  free  part  of  the  leaves  is 
strengthened  by  lengthwise  veins,  and  they  form  edges  that  never  tear  nor 
break.  They  are  very  flexible,  and  therefore  yield  to  the  wind  rather  than 
defy  it.  If  we  look  at  a leaf  in  cross-section,  we  can  see  the  two  thick 
walls  strengthened  by  the  framework  of  stiff  veins  which  divide  the  in- 
terior into  long  cells.  If  we  cut  the  leaf  lengthwise  we  can  see  that  these 
long  cells  are  supported  by  stiff,  coarse  partitions. 

Where  the  leaf  clasps  the  stem,  it  is  very  stiff  and  will  break  rather 
than  bend.  The  texture  of  the  leaf  is  soft  and  smooth,  and  its  shade  of 
green  is  attractive.  The  length  of  the  leaves  is  often  greater  than  that  of 
the  blossom  stalk,  and  their  graceful  curves  contrast  pleasantly  with  its 
ramrod-like  stiffness.  It  is  no  wonder  that  artists  and  the  decorators  have 
used  the  cat-tail  lavishly  as  a model.  It  is  interesting  to  note  that  the 
only  portion  of  the  leaves  injured  by  the  wind  is  the  extreme  tip. 

The  cat-tail  is  adapted  for  living  in  swamps  where  the  soil  is  wet  but 
not  under  water  all  the  time.  When  the  land  is  drained,  or  when  it  is 
flooded  for  a considerable  time,  the  cat-tails  die  out  and  disappear.  They 
usually  occur  in  marshy  zones  along  lakes  or  streams ; and  such  a zone  is 
always  sharply  defined  by  dry  land  on  one  side  and  water  on  the  other. 
The  cat -tail  roots  are  fine  and  fibrous  and  are  especially  fitted,  like  the 
roots  of  the  tamarack,  to  thread  the  mud  of  marshy  ground  and  thus  gain 
a foothold.  The  cat-tails  form  one  of  the  cohorts  in  the  phalanx  of 
encroaching  plants,  like  the  reeds  and  rushes,  which  surround  and,  by  a 
slow  march  of  years,  finally  conquer  and  dry  up  ponds.  But  in  this  they 
overdo  the  matter,  since  after  a time  the  soil  becomes  too  dry  for  them 
and  they  disappear,  giving  place  to  other  plants  which  find  there  a con- 
genial environment.  The  place  where  I studied  the  cat-tails  as  a child  is 
now  a garden  of  joe  pye  weed  and  wild  sunflowers.

LESSON  CXXXIV 
The  Cat-tail 

Leading  thought — The  cat-tail  is  adapted  to  places  where  the  soil  is  wet 
but  not  under  water;  its  pollen  is  scattered  by  the  wind,  and  its  seeds  are 
scattered  by  wind  and  water.  Its  leaves  and  stalks  are  not  injured  nor 
broken  by  the  wind. 

Method- — As  this  is  primarily  a geography  lesson,  it  should  be  given  in 
the  field  if  possible ; otherwise  the  pupils  must  explore  for  themselves  to 
discover  the  facts.  The  plant  itself  can  be  brought  into  the  schoolroom 
for  study.  When  stadying  the  seeds,  it  is  well  to  be  careful,  or  the  school- 
room and  the  pupils  will  be  clothed  with  the  pappus  for  weeks. 

Observations — i.  Where  are  the  cat-tails  found?  Is  the  land  on 
which  they  grow  under  water  all  the  year?  At  any  part  of  the  year ? Is 
it  dry  land  all  the  year?  What  happens  to  the  cat-tails,  if  the  land  on 
which  they  grow  is  flooded  for  a season  ? What  happens  tc  them,  if  the 
land  is  drained? 

2.  How  wide  a strip  do  the  cat-tails  cover,  where  you  have  found 
them?  Are  they  near  a pond  or  brook  or  stream  Do  they  grow  out  in

the  stream?  Why  do  they  not  extend  further  inland?  What  is  the 
character  of  the  soil  on  which  they  grow? 

3 . What  sort  of  a root  has  the  cat-tail  ? Why  is  this  root  especially 
adapted  to  the  soil  where  cat-tails  grow?  Describe  the  rootstock. 

4.  The  cat-tail  plant.  Are  the  leaves  arranged  opposite  or  alternate? 

Tear  off  a few  of  the  leaves  and  describe  the  difference  between  the  lower 
and  the  upper  end  of  a leaf  as  follows:  How  do  they  differ  in  shape? 

Texture?  Pliability?  Color?  Width?  Does  each  leaf  completely 
encircle  the  stalk  at  its  base?  Of  what  use  is  this  to  the  plant?  Of  what 
use  is  it  to  have  the  plant  stiff er  where  the  leaves  clasp  the  stalk?  What 
would  happen  in  a wind  storm  if  this  top-heavy,  slender  seed  stalk  was 
bare  and  not  supported  by  the  leaves  ? What  is  the  special  enemy  of  long, 
tall,  slender-leafed  plants? 

5.  Take  a single  leaf,  cut  it  across  near  where  it  joins  the  main  stalk 
and  also  near  its  tip.  Look  at  the  cross-section  and  see  how  the  leaf  is 
veined.  What  do  its  long  veins  or  ribs  do  for  the  leaf?  Split  the  leaf 
lengthwise  and  see  what  other  supports  it  has.  Does  the  cat-tail  leaf  break 
or  tear  along  its  edges  easily?  Does  the  wind  injure  any  part  of  the  leaf? 

6.  Study  the  cat-tail  flowers  the  last  half  of  June.  Note  the  part 
that  will  develop  into  the  cat’s  tail.  Describe  the  part  above  it.  Can 
you  see  where  the  pollen  comes  from?  The  pistillate  flowers  which  are  in 
the  plush  of  the  cat-tail  have  no  sepals,  petals,  odor  nor  nectar.  Do 
you  think  that  their  pollen  is  carried  to  them  by  the  bees?  How  is  it 
carried? 

7.  Examine  the  cat-tail  in  fall  or  winter.  What  has  happened  to 
that  part  of  the  stalk  above  the  cat-tail  where  the  anthers  grew?  Study

two  or  three  of  the  seeds,  and  see  how  they  are  provided  for  traveling. 
What  scatters  them?  Will  the  cat-tail  seed  balloons  float?  Would  the 
wind  or  the  water  be  more  likely  to  carry  the  cat-tail  seeds  to  a place 
where  they  would  grow?  Describe  the  difference  between  the  cat -tail 
balloon  and  the  thistle  balloon. 

8.  How  crowded  do  the  cat-tail  plants  grow?  How  are  they  arranged 
to  keep  from  shading  each  other?  In  how  many  ways  is  the  wind  a friend 
of  the  cat-tails? 

9.  How  do  the  cat -tails  help  to  build  up  land  and  make  narrower 
ponds  and  streams?

LESSON  CXXXV 

A Type  Lesson  for  a Composite  Flower 

Leading  thought — Many  plants  have  their  flowers  set  close  together  to 
make  a mass  of  color,  like  the  geraniums  or  the  clovers.  But  there  are 
other  plants  where  the  flowers  of  one  flower-head  act  like  the  members  of 
a family,  those  at  the  center  doing  a certain  kind  of  work  for  the  produc- 
tion of  seed,  and  those  around  the  edges  doing  another  kind  of  work.  The 
sunflower,  goldenrod,  asters,  daisies,  cone-flower,  thistle,  dandelion,  bur- 
dock, everlasting,  and  many  other  common  flowers  have  their  blossoms 
arranged  in  this  way.  Before  any  of  the  wild-flower  members  of  this 
family  are  studied,  the  lesson  on  the  garden  sunflower  should  be  given. 
(See  Lesson  CLXII). 

Method — These  flowers  may  be  studied  in  the  schoolroom  with  sug- 
gestions for  field  observations.  A lens  is  almost  necessary  for  the  study 
of  most  of  these  flowers. 

Observations — 1.  Can  you  see  that  what  you  call  the  flower  consists 
of  many  flowers  set  together  like  a beautiful  mosaic?  Those  at  the  center 
are  called  disk-flowers;  those  around  the  edges  banner  or  ray-flowers. 

2.  Note  that  the  flowers  around  the  edges  have  differently  shaped 
corollas  than  those  at  the  center.  How  do  they  differ?  Why  should 
these  be  called  the  banner  flowers  ? Why  should  they  be  called  the  ray- 
flowers?  How  many  banner-flowers  are  there  in  the  flower  family  you 
are  studying?  How  are  the  banners  arranged  to  make  the  flower-head 
more  attractive  ? Cut  off  or  pull  out  all  the  banner-flowers  and  see  how 
the  flower-head  looks.  What  do  the  banner-flowers  hold  out  their  ban- 


Wild-Flower  Study  555 

ners  for?  Is  it  to  attract  us  or  the  insects ? Has  the  banner-flower  any 
stigma  or  stamens  ? 

3.  Study  the  flowers  at  the  center.  Are  they  open,  or  are  they  un- 
folded, buds?  Can  you  make  a sketch  of  how  they  are  arranged?  Are 
any  of  the  florets  open  ? What  is  the  shape  and  the  color  of  the  corolla  ? 
Can  you  see  the  stamen-tubes  pushing  out  from  some  ? What  color  are 
the  stamen-tubes  ? Can  you  see  the  two-parted  stigmas  in  others  ? What 
color  is  the  pollen.  Do  the  florets  at  the  center  or  at  the  outside  of  the 
disk  open  first  ? When  they  first  open,  do  you  see  the  stamen-tube  or  the 
stigma  ? 

4.  The  flower-heads  are  protected  before  they  open  with  overlapping 
bracts,  which  may  be  compared  to  a shingled  house  protecting  the  flower 
family.  As  the  flower-head  opens,  these  bracts  are  pushed  back  beneath 
it.  Describe  the  shape  of  these  bracts.  Are  they  set  in  regular,  over- 
lapping rows?  Are  they  rough  or  smooth  ? Do  they  end  bluntly,  with  a 
short  point,  with  a long  point,  with  a spine,  or  a hook?  How  do  the 
bracts  act  when  the  flower  family  goes  to  sleep?  Do  they  remain  after 
the  seeds  are  ripened  ? 

5.  Take  a flower-head  apart,  and  examine  the  florets.  Can  you  see 
what  part  of  the  floret  will  be  the  seed?  Is  there  a fringe  of  pappus  above 
it?  If  so,  what  will  this  be  on  the  seed? 

6.  Study  the  ripe  seeds.  How  are  they  scattered?  Do  they  have 
balloons?  Is  the  balloon  close  to  the  seed?  Is  it  fastened  to  all  parts  of 
it? 


THE  GOLDENROD 


Teacher's  Story 


Coldenrcd. 


Once  I was  called  upon  to  take  some 
children  into  the  field  to  study  autumn 
flowers.  The  day  we  studied  goldenrod, 
I told  them  the  following  story  on  the 
way,  and  I found  that  they  were  pleased 
with  the  fancy  and  through  it  were  led 
to  see  the  true  purpose  of  the  goldenrod 
blossoming: 

“There  are  flowers  which  live  in  vil- 
lages and  cities,  but  people  who  also 
live  in  villages  and  cities  are  so  stupid 
that  they  hardly  know  a flower  city 
when  they  see  it.  This  morning  we 
are  going  to  visit  a golden  city  where  the 
people  are  all  dressed  in  yellow,  and 
where  they  live  together  in  families;  and 
the  families  all  live  on  top  of  their  little, 
green,  shingled  houses,  which  are  set  in 
even  rows  along  the  street.  In  each  of 
these  families,  there  are  some  flowers 
whose  business  it  is  to  furnish  nectar  and 
pollen  and  to  produce  seeds  which  have 
fuzzy  balloons;  while  there  are  other 


556 


Handbook  of  N ature -Study 


flowers  in  each  family  which  wave  yellow  banners  to  all  the  insects  that 
pass  by  and  signal  them  with  a code  of  their  own,  thus:  ‘Here,  right 

this  way  is  a flower  family  that  needs  a bee  or  a beetle  or  an  insect  of 
some  sort  to  bring  it  pollen  from  abroad,  so  that  it  can  ripen  its  seed ; and 
it  will  give  nectar  and  plenty  of  pollen  in  exchange.’  Of  course,  if  the 
flowers  could  walk  around  like  people,  or  fly  like  insects,  they  could 
fetch  and  carry  their  own  pollen,  but  as  it  is,  they  have  to  depend 
upon  insect  messengers  to  do  this  for  them.  Let  us  see  who  of  us  will  be 
the  first  to  guess  what  the  name  of  this  golden  city  is,  and  who  will  be 
the  first  to  find  it.” 


A street  in  goldenrod  city. 


The  children  were  delighted  with  this  riddle  and  soon  found  the  golden- 
rod  city.  We  examined  each  little  house  with  its  ornate,  green  “shingles.” 
These  little  houses,  looking  like  cups,  were  arranged  on  the  street  stem, 
right  side  up,  in  an  orderly  manner  and  very  close  together;  and  where 
each  joined  the  stem,  there  was  a little,  green  bract  for  a doorstep. 
Living  on  these  houses  we  found  the  flower  families,  each  consisting  of  a 
few  tubular  disk-flowers  opening  out  like  bells,  and  coming  from  their 
centers  were  the  long  pollen-tubes  or  the  yellow,  two-parted  stigmas. 
The  ray-flowers  had  short  but  brilliant  banners ; and  they,  as  well  as  the 
disk-flowers,  had  young  seeds  with  pretty  fringed  pappus  developing  upon 
them.  The  banner-flowers  were  not  set  so  regularly  around  the  edges  as 
in  the  asters ; but  the  families  were  such  close  neighbors,  that  the  banners 
reached  from  one  house  to  another.  And  all  of  the  families  on  all  of  the 
little,  green  streets  were  signalling  insects,  and  one  boy  said,  “They  must 
be  making  a very  loud  yellow  noise.”  We  found  that  [very  many 
insects  had  responded  to  this  call — honeybees,  bumblebees,  mining  and 
carpenter  bees,  blue-black  blister  beetles  with  short  wings  and  awkward 
bodies,  beautiful  golden-green  chalcid  flies,  soldier  beetles  and  many 
others ; and  we  found  the  spherical  gall  and  the  spindle-shaped  gall  in  the 
stems,  and  the  strange  gall  up  near  the  top  which  grew  among  the  leaves. 

Unless  one  is  a trained  botanist  it  is  wasted  energy  to  try  to  distinguish 
any  but  the  well-marked  species  of  goldenrod ; for,  according  to  Gray,  we 
have  56  species,  the  account  of  which  makes  twelve  pages  of  most  unin- 
teresting reading  in  the  new  Manual.  The  goldenrod  family  is  not  in  the 
least  cliquish,  the  species  have  a habit  of  interbreeding  to  the  confusion  of 
the  systematic  botanist.  Matthew’s  Field  Book  serves  as  well  as  any  for 
distinguishing  the  well-marked  species.

LESSON  CXXXVI 

The  Goldenrod 

Leading  thought — In  the  goldenrod  the  flower-heads  or  families  are  so 
small  that,  in  order  to  attract  the  attention  of  the  insects,  they  are  set 
closely  together  along  the  stem  to  produce  a mass  of  color. 

Method — Bring  to  the  school-room  any  kind  of  goldenrod,  and  give  the 
lesson  on  the  flowers  there.  This  should  be  followed  by  a field  excursion 
to  get  as  many  kinds  of  goldenrod  as  possible.  The  following  observa- 
tions will  bring  out  differences  in  well-marked  species  : 

Observations — i.  Use  Lesson  CXXXV  to  study 
the  flower.  How  many  banner-flowers  in  the  family  ? 
How  many  disk-flowers?  Are  the  banners  arranged 
as  regularly  around  the  edges  as  in  the  asters  and 
daisies?  How  are  the  flower-heads  set  upon  the 
stems?  Which  flower-heads  open  first — those  at 
the  base  or  at  the  tip  of  the  stem?  Do  the  upper 
stems  of  the  plant  blossom  before  those  lower  down  ? 

2.  Do  the  stems  bearing  flowers  come  from  the 
axils  of  the  leaves?  What  is  the  general  shape  of 
the  flower  branches?  Do  they  come  off  evenly  at 
Disk-flower  and  ban-  each  side,  or  more  at  one  side?  Are  the  flower 
ner-fiower  of  goldenrod.  branches  long  or  short?  Make  a sketch  of  the 
general  shape  of  the  goldenrod  you  are  studying. 

3.  Is  the  stem  smooth,  downy,  or  covered  with  bloom?  What  is 
its  color?  In  cross-section,  is  it  circular  or  angular?  • 

4.  What  is  the  shape  and  form  of  the  edges  of  the  lower  leaves  ? The 
upper  ones?  Are  they  set  with,  or  without,  petioles  on  the  stem?  Do 
they  have  a heart-shaped  base?  Are  the  leaves  smooth  or  downy?  Are 
they  light,  or  dark  green? 

5.  Field  notes.  Where  do  you  find  the  goldenrod  growing?  Do  you 
find  one  kind  growing  alone  or  several  kinds  growing  together?  Do  you 
find  any  growing  in  the  woods  ? If  so,  how  do  they  differ  in  shape  from 
those  in  the  field? 

6.  How  many  kinds  of  insects  do  you  find  visiting  goldenrod  flowers? 
How  many  kinds  of  galls  do  you  find  on  the  goldenrod  stems  and  leaves? 

7 . Study  the  goldenrods  in  N ovember.  Describe  their  seeds  and  how 
they  are  scattered. 

“I  am  alone  with  nature, 

With  the  soft  September  day; 

The  lifting  hills  above  me, 

With  goldenrod  are  gay. 

Across  the  fields  of  ether 
Flit  butterflies  at  play; 

And  cones  of  garnet  sumac 
Glow  down  the  country  way. 

“ The  autumn  dandelion 

Beside  the  roadway  burns; 

Above  the  lichened  boulders 
Quiver  the  plumed  ferns. 

The  cream-white  silk  of  the  milkweed 
Floats  from  it’s  sea-green  pod; 

From  out  the  mossy  rock-seams 
Flashes  the  goldenrod."

THE  ASTERS 


Teacher's  Story 


ET 


us  believe  that  the  scientist  who  gave  to  the 
asters  their  Latin  name  was  inspired.  Aster 
means  star  and  these,  of  all  flowers,  are  most 
starlike ; and  in  beautiful  constellations  they 
border  our  fields  and  woodsides.  The  aster 
combination  of  colors  is  often  exquisite.  Many 
have  the  rays  or  banners  lavender,  oar-shaped 
and  set  like  the  rays  of  a star  around  the  yellow 
disk-flowers;  these  latter  send  out  long,  yellow 
anther  tubes,  overflowing  with  yellow  pollen, 
and  add  to  the  stellar  appearance  of  the  flower- 
head. 


“And  asters  by  the  brookside  make  asters  in  the  brook. 


Thus  sang  H.  H.  of  these  beautiful  masses  of  autumn  flowers.  But  if 
H.  H.  had  attempted  to  distinguish  the  species,  she  would  have  said 
rather  that  asters  by  the  brookside  make  more  asters  in  the  book;  for 
Gray’s  Manual  assures  us  that  we  have  77  species  including  widely  differ- 
ent forms,  varying  in  size,  color  and  also  as  to  the  environment  in  which 
they  will  grow.  They  range  from  the  shiftless  woodland  species,  which 
has  a few  whitish  ray-flowers  hanging  shabbily  about  its  yellow  disk  and 
with  great,  coarse  leaves  on  long,  gawky  petioles  climbing  the  zigzag  stem, 
to  the  beautiful  and  dignified  New  England  aster,  which  brings  the 
glorious  purple  and  orange  of  its  great  flower-heads  to  decorate  our  hills 
in  September  and  October. 

Luckily,  there  are  a few  sp  cies  which  are  fairly  well  marked,  and  still 
more  luckily,  it  is  not  of  any  consequence  whether  we  know  the  species  or 
not,  so  far  as  our  enjoyment  of  the  flowers  themselves  is  concerned.  The 
outline  of  this  lesson  will  call  the  attention  of  the  pupils  to  the  chief  points 
of  difference  and  likeness  in  the  aster  species,  and  they  will  thus  learn  to 
discriminate  in  a general  way.  The  asters,  like  the  goldenrods,  begin  to 
bloom  at  the  tip  of  the  branches,  the  flower-heads  nearest  the  central 
stem,  blooming  last.  All  of  the  asters  are  very  sensitive,  and  the  flower- 
heads  will  close  promptly  as  soon  as  they  are  gathered.  The  ray  or 
banner-flowers  are  pistillate,  and  therefore  develop  seed.  The  seed  has

attached  to  its  rim  a ring  of  pappus,  and  is  ballooned  to  its  final  destina- 
tion. In  November,  the  matured  flower-heads  are  fuzzy,  with  seeds 
ready  for  invitations  from  any  passing  wind  to  fly  whither  it  listeth. 


LESSON  CXXXVII 


The  Asters 


Leading  thought — There  are  very  many  different  kinds  of  asters,  and 
they  all  have  their  flowers  arranged  similarly  to  those  of  the  sunflower. 

Method — Have  the  pupils  collect 
as  many  kinds  of  asters  as  possible, 
being  careful  to  get  the  basal  leaves 
and  to  take  notes  on  where  each 
kind  was  found — that  is,  whether  in 
the  woodlands,  by  the  brooksides 
or  in  the  open  fields.  This  lesson 
should  follow  that  on  the  sunflower. 

Observations — i.  What  was  the 
character  of  the  soil  and  surround- 
ings where  this  aster  grew?  Were 
there  large  numbers  of  this  kind 
growing  together?  Were  the  flow- 
ers wide  open  when  you  gathered 
them?  How  soon  did  they  close? 

2.  How  high  did  the  plants 
stand  when  growing?  Were  there 
many  flowers,  or  few,  on  each  plant? 

3 . Study  the  lower  and  the 

upper  leaves.  Describe  each  as 
follows:  the  shape,  the  size,  the 

edges,  the  way  it  was  joined  to  the 
stem. 

4.  Is  the  stem  many-branched 
or  few?  Do  the  branches  bearing 
flowers  extend  in  all  directions? 
Are  the  stems  hairy  or  smooth,  and 
what  is  their  color  ? 

5.  What  is  the  diameter  of  the 
single  flower-head?  What  is  the 
color  of  the  ray-flowers?  How 
many  ray  or  banner-flowers  are 
there?  What  is  the  shape  of  a 
single  banner  as  compared  with 
that  of  a sunflower?  What  are  the 
colors  of  the  disk-flowers?  Of  the 

pollen  ? Do  the  disk-flowers  change  color  after  blossoming ? 

6.  Look  at  the  bracts  below  the  flower-head.  Are  they  all  the  same 
sh^pe?  What  is  their  color?  Do  they  have  recurved  tips  or  do  they 
overlap  closely?  Are  they  sticky? 

7.  Take  the  aster  flower-head  apart  and  look  at  it  with  a lens.  In  a 
disk-flcwer,  note  the  young  seed,  the  pappus,  the  tubular  five-parted 
corolla,  the  anther  tube  and  the  stigmas.  In  the  ray-flower,  find  the 
voung  seed,  the  pappus  and  the  stigma.

8.  Watch  the  bees  working  on  asters,  and  find  where  they  thrust  their 
tongues  to  reach  the  nectar. 

9.  Study  an  aster  plant  in  November,  and  describe  the  seeds  and  how 
they  are  scattered.

THE  WHITE  DAISY 
Teacher's  Story 

Every  child  loves  this  flower,  and  yet  it  is  not  well  understood; 
it  is  always  at  hand  for  study  from  June  until  the  frosts  have  laid 
waste  the  fields.  However  much  enjoyment 
we  get  from  the  study  of  this  beautiful  flower- 
head,  we  should  study  the  plant  as  a weed 
also,  for  it  is  indeed  a pest  to  those  farmers  who 
do  not  practice  a rotation  of  crops.  Its  root  is 
long  and  tenacious  of  the  soil,  and  it  ripens  many 
seeds  which  mingle  with  the  grass  seed,  and  thus 
the  farmer  sows  it  to  his  own  undoing.  The 
bracts  of  the  involucre,  or  the  shingles  of  the 
daisy-house,  are  rather  long,  and  have  parch- 
ment like  margins.  They  overlap  in  two  or  three 
rows.  In  the  daisy  flower-head,  the  banner- 
flowers  are  white ; there  may  be  twenty  or  thirty 
of  these,  making  a beautiful  frame  for  the  golden- 
yellow  disk-flowers.  The  banner  is  rather  broad, 
is  veined,  and  toothed  at  the  tip.  The  banner- 
flower  has  a pistil  which  shows  its  two-parted 
stigma  at  the  base  of  the  banner,  and  it  matures  a 
seed.  The  disk-flowers  are  brilliant  yellow, 
tubular,  rather  short,  with  the  five  points  of  the 


Daisy  florets.

corolla  curling  back.  The  anther-tubes  and  the  pollen  are  yellow,  so 
are  the  stigmas.  The  arrangement  of  the  buds  at  the  center  is  exceed- 
ingly pretty.  The  flowers  develop  no  pappus,  and  therefore  the  seeds 
have  no  balloons.  They  depend  upon  the  ignorance  and  helplessness  of 
man  to  scatter  their  seeds  far  and  wide  with  the  grass  and  clover  seed, 
which  he  sows  for  his  own  crops.  It  was  thus  that  it  came  to  America, 
and  in  this  manner  still  continues  to  flaunt  its  banners  in  our  meadows 
and  pastures.  The  white  daisy  is  not  a daisy,  but  a chrysanthemum.  It 
has  never  been  called  by  this  name  popularly,  but  has  at  least  twenty 
other  common  names,  among  them  the  ox-eye  daisy,  moon-penny,  and 
herb-Margaret. 

LESSON  CXXXVIII 
The  White  Daisy 

Leading  thought — The  white-daisy  is  not  a single  flower  but  is  made  up 
of  many  little  flowers  and  should  be  studied  by  the  outline  given  in  Lesson

THE  YELLOW  DAISY,  OR  BLACK-EYED  SUSAN 
Teacher's  Story 

These  beautiful,  showy  flowers  have  rich  contrasts  in  their  color 
scheme.  The  ten  to  twenty-ray  flowers  wave  rich,  orange  banners 

around  the  cone  of 
purple-brown  disk-flow- 
ers. The  banners  are 
notched  and  bent  down- 
ward at  their  tips ; each 
banner-flower  has  a pis- 
til, and  develops  a seed. 
The  disk-flowers  are 
arranged  in  a conical, 
button-like  center;  the 
corollas  are  pink-purple 
at  the  base  of  the  tube, 
but  their  five  recurved, 
pointed  lobes  are  pur- 
ple-brown. The  anther- 
tube  is  purple-brown 
and  the  stigmas  show 
the  same  color;  but 
the  pollen  is  brilliant 
orange,  and  adds  much 
to  the  beauty  of  the 
rich,  dark  florets  when 
it  is  pushed  from  the 
anther-tubes.  There  is 
no  pappus  developed, 
and  the  seeds  are  car- 
ried as  are  the  seeds  of 
the  white  daisy,  by  be- 
ing harvested  with  the 
seeds  of  grain. 

The  stem  is  strong 
and  erect;  the  bracts 
of  the  involucre,  or 
“shingles”,  are  long, 
narrow  and  hairy,  the  lower  ones  being  longer  and  wider  than  those 
above;  they  all  spread  out  flat,  or  recurve  below  the  open  flower-head. 
In  blossoming,  first  the  ray-flowers  spread  wide 
Itheir  banners;  then  the  flowerets  around  the  base 
of  the  cone  open  and  push  out  their  yellow  pollen 
through  the  brown  tubes;  then  day  by  day  the 
blossoming  circle  climbs  toward  the  apex — a beau- 
tiful way  of  blossoming  upward.

THE  THISTLE 
Teacher's  Story 

looking  at  the  thistle  from  its  own 
standpoint,  we  must  acknowledge  it  to 
be  a beautiful  and  wonderful  plant . It 
is  like  a knight  of  old  encased  in  armor 
and  with  lance  set,  ready  for  the  fray. 
The  most  impressive  species  is  the  great 
pasture,  or  bull,  thistle  ( C . pumilis ), 
which  has  a blossom-head  three  inches 
across.  This  is  not  so  common  as  the 
lance-leaved  thistle,  which  ornaments 
roadsides  and  fence  corners,  where  it 
may  remain  undisturbed  for  the  neces- 
sary second  year  of  growth  before  it 
can  mature  its  seeds.  The  most  per- 
nicious species,  from  the  farmer’s 
Its  roots  are  perennial,  and  they  invade 
They  creep  for  yards  in  all  directions, 
just  deep  enough  to  be  sure  of  moisture,  and  send  up  new  plants  here  and 
there,  especially  if  the  main  stalk  is  cut  off.  Roots  severed  by  the  plow, 
send  up  shoots  from  both  of  the  broken  parts.  Not  so  with  the  common 
thistle,  which  has  a single  main  root,  with  many  fibrous  and  clustered 
branches  but  with  no  side  shoots. 

The  stalk  of  the  lance-leaved  thistle  is  strong  and  woody,  and  is 
closely  hugged  by  pricky  leaf  stems,  except  for  a few  inches  above  the  root. 
The  leaves  are  placed  alternately  - 
on  the  stalk;  they  are  deep  green, 
covered  above  with  rough  and 
bristling  hairs,  and  when  young  are 
covered  on  the  under  side  with 
soft,  gray  wool  which  falls  away 
later.  The  spines  grow  on  the 
edges  of  the  leaves,  which  are  deeply 
lobed  and  are  also  somewhat  wavy 
and  ruffled,  thus  causing  the  savage 
spears  to  meet  the  enemy  in  any 
direction.  The  ribs  and  veins  are 
without  spines.  Small  buds  or 
branches  may  be  found  at  the  axils 
of  the  leaves;  and  if  a plant  is 
beheaded,  those  axiliary  buds  near- 
est the  top  of  (the  stem  will  grow 
vigorously. 

The  thistle  flowers  are  purple  in 
color  and  very  fragrant ; they  grow 
in  single  heads  at  the  summit  of 
the  stalk,  and  from  the  axils  of  the 
upper  leaves.  The  topmost  heads 
open  first.  Of  the  individual 

flowers  in  the  head,  those  of  the  Lance-leaved  thistle.

outer  rows  first  mature  and  protrude  their  pistils;  the  pollen  grains 
are  white.  In  each  flower,  the  corolla  is  tube-shaped  and  purple,  part- 
ing into  five  fringelike  lobes  at  the  top,  and  fading  to  white  at  its 
nectar-filled  base. 

The  stamens  have  dark  purple  anthers,  united  in  a tube  in  which 
their  pollen  is  discharged.  The  pistil,  ripening  later,  shoves  out  the  pollen 
with  its  stigma,  which  at  first  is  blunt  at  the  end,  its  two-parted  lips  so 
tightly  held  together  that  not  a grain  of  its  own  flower’s  pollen  can  be 
taken.  But  when  thrust  far  out  beyond  the  anther-tube,  the  two-parted 
stigma  opens  to  receive  the  pollen  which  is  brought  by  the  many  winged 
visitors ; for  of  all  flowers,  the  thistles  with  their  abundant  nectar  are  the 
favorites  of  insects.  Butterflies  of  many  species,  moths,  beetles  and  bees 
— especially  the  bumblebees — are  the  happy  guests  of  the  thistle  blooms. 

The  thistles  believe  in  large  families ; a single  head  of  the  lance-leaved 
thistle  has  been  known  to  have  1 16  seeds.  The  seeds  are  oblong,  pointed, 
little  akenes,  with  hard  shells.  Very  beautiful  and  wonderful  is  the 
pappus  of  the  thistle ; it  is  really  the  calyx  of  the  flower,  its  tube  being  a 
narrow  collar,  and  the  lobes  are  split  up  into  the  silken  floss. 
At  the  larger  end  of  the  seed  is  a circular  depression  with  a 
tiny  hub  at  its  center;  into  this  ring,  and  around  the  knob,  is 
fitted  the  collar  which  attaches  the  down  to  the  seed.  Hold 
the  balloon  between  the  eye  and  the  light,  and  it  is  easy  to  see 
that  the  down  is  made  of  many-branched  plumes  which  inter- 
lace and  make  it  more  buoyant.  When  first  taken  from  its 
crowded  position  on  the  flower-head,  the  pappus  surrounds 
-,j  a n the  corolla  in  a straight,  close  tube;  but  if  placed  for  just  a few 
.Aim  moments  in  the  sun,  the  threads  spread,  the  filmy  branchlets 
■Mil  open  out,  and  a fairy  parachute  is  formed,  with  the  seed  hang- 
mrn  ing  beneath ; if  no  breath  of  air  touches  it  while  spreading,  it 
| III  will  sometimes  form  a perfect  funnel;  when  blown  upon,  some 

|/I  of  the  silken  threads  lose  their  places  on  the  rim  and  rise  to  the 

If  center.  When  driven  before  the  breeze,  this  balloon  will  float 
W for  a long  distance.  When  it  falls,  it  lets  go  of  the  seed  as  the

flower-head.  por  ^he  season  after  the  seed  has  rooted,  the  thistle 
develops  only  rosettes,  meanwhile  putting  down  roots  and 
becoming  permanently  established.  The  next  season,  the  flowers  and 
seeds  are  developed,  and  then  the  plant  dies.  Would  that  this  fact  were 
true  of  the  Canada  thistle;  but  that,  unfortunately,  is  perennial,  and  its 
persistent  roots  can  only  be  starved  out  by  keeping  the  stalks  cut  to  the 
ground  for  the  entire  season.  This  thistle  trusts  to  its  extensively  creep- 
ing rootstocks  more  than  to  its  seeds  for  retaining  its  foothold  and  for 
spreading.  While  it  develops  many  seed  balloons,  a large  number  of  its 
seeds  are  infertile  and  will  not  grow. 

LESSON  CXL 

The  Common,  or  Lance-leaved,  Thistle 
Leading  thought — The  thistle  is  covered  with  sharp  spines,  and  these 
serve  to  protect  it  from  grazing  animals.  It  has  beautiful  purple  flowers, 
arranged  in  heads  similar  to  those  of  the  sunflower. 


Wild-Flower  Study 


565 


Method — A thistle  plant 

brought  into  the  schoolroom— 
root  and  all — and  placed  in  water 
will  serve  well  for  this  lesson. 
The  questions  should  be  given 
the  pupils  as  to  where  thistles 
are  found.  Any  thistle  will  do 
for  the  lesson. 

Observations — 1.  Where  do 

you  find  the  thistles  growing? 
Do  you  find  more  than  one  spe- 
cies growing  thickly  together? 
Do  you  find  any  of  the  common 
thistles  growing  in  soil  which  has 
been  cultivated  this  season? 

2.  Describe  the  stalk,  is  it 
smooth?  Is  it  weak  or  strong 
and  woody?  What  sort  of  root 
has  it? 

3.  Do  the  leaves  grow  alter- 
nately or  opposite?  Are  they 
smooth  or  downy  on  one  or  both 
sides?  Do  the  spines  grow 
around  the  margins,  or  on  the 
leaves  and  veins?  Are  the  leaf 
edges  flat,  or  wavy  and  ruffled? 

4.  How  does  this  affect  the 
direction  in  which  the  spines 
point?  Are  the  leaves  entire  or 
deeply  lobed?  Have  they  peti- 
oles, or  are  they  attached  directly 
to  the  stalk? 

5.  Note  if  any  buds  or  small 
branches  nestle  in  the  axils  of 
the  lower  leaves.  What  effect 
does  cutting  the  main  stalk  seem 
to  have  on  each  side  shoot? 

6.  Do  the  flower-heads  of  the 
thistle  grow  singly  or  in  clusters? 
Do  they  come  from  the  summit 
of  the  stalk,  or  do  they  branch 
from  its  sides?  Which  blossom- 
heads  open  first — the  topmost  or 
those  lowest  on  the  stalk?  Are 
the  flowers  fragrant?  What  in- 
sects do  you  most  often  see 
visiting  thistle  blossoms  for  pol- 
len or  nectar?  Study  the  thistle  flower  according  to  Lesson  CXXXV. 

7.  Carefully  study  a thistle  balloon.  How  is  the  floss  attached  to  the 
seed?  Is  it  attached  to  the  smaller,  or  the  larger  end?  Hold  the  thistle 
balloon  between  your  eye  and  the  light.  Does  the  down  consist  of  single 
separate  hairs,  or  have  they  many  fine  branches?  Hovr  is  the  down

arranged  when  all  the  flowers  are  packed  together  in  the  thistle-head? 
Take  a seed  from  among  its  closely  packed  fellows  in  the  thistle-head,  and 
put  it  in  the  sun  or  in  a warm,  dry  place  where  it  cannot  blow  away.  How 
long  does  it  take  for  the  balloon  to  open  out?  What  is  its  shape?  Is 
there  any  down  at  the  center  of  the  balloon  or  is  it  arranged  in  a funnel- 
shaped  ring?  Can  you  find  a perfectly  globular  thistle  balloon  with  the 
seeds  still  attached  to  it?  How  far  do  you  think  the  thistle  balloons 
might  travel  ? 

8.  If  a thistle  seed  finds  a place  for  planting  during  the  autumn,  how 
does  the  young  plant  look  the  next  season?  Describe  the  thistle  rosette. 
What  growth  does  it  make  the  second  summer  ? What  happens  to  it  then  ? 

9.  Why  can  you  not  cultivate  out  the  Canada  thistles  as  you  can  the 
other  species? 


A successful  life. 


THE  BURDOCK 
Teacher's  Story 

Psychologists  say  that  all  young  things  are  selfish,  and  the  young 
burdock  is  a shining  example  of  this  principle.  Its  first  leaves  are  broad 
and  long,  with  long  petioles  by  means  of  which  they  sprawl  out  from  the 
growing  stem  in  every  direction,  covering  up  and  choking  out  all  the  lesser 
plants  near  them.  In  fact,  the  burdock  remains  selfish  in  this  respect 
always,  for  its  great  basal  leaves  see  to  it  that  no  other  plants  shall  get  the 
good  from  the  soil  near  its  own  roots.  One  wonders  at  first  how  a plant 
with  such  large  leaves  can  avoid  shading  itself ; but  there  are  some  people 


Wild-Flower  Study 


S<57 


very  selfish  toward  the  world  who  are  very  thoughtful  of  their  own  fami- 
lies, and  the  burdock  belongs  to  this  class.  We  must  study  carefully  the 
arrangement  of  its  leaves  in  order  to  understand  its  cleverness.  The  long 
basal  leaves  are  stretched  out  flat;  the  next  higher,  somewhat  smaller 
ones  are  lifted  at  a polite  angle  so  as  not  to  stand  in  their  light.  This 
courtesy  characterizes  all  the  leaves  of  the  plant,  for  each  higher  leaf  is 
smaller  and  has  a shorter  petiole,  which  is  lifted  at  a narrower  angle  from 
the  stalk;  and  all  the  leaves  are  so  nicely  adjusted  as  to  form  a pyramid, 
allowing  the  sunlight  to  sift  down  to  each  part.  While  some  of  the  upper- 
most leaves  may  be  scarcely  more  than  an  inch  long,  the  lower  ones  are 
very  large.  They  are  pointed  at  the  tip  and  wide  at  the  base ; where  the 
leaf  joins  the  petiole  it  is  irregular,  bordered  for  a short  distance  on  each 
side  with  a vein,  and  then  finished  with  a “flounce,”  which  is  so  full  that  it 
even  reaches  around  the  main  stem — another  device  for  getting  more 
sunlight  for  itself  and  shutting  it  off  from  plants  below.  On  the  lower 
side,  the  leaf  is  whitish  and  feltlike  to  the  touch ; above  it  is  a raw  green, 
often  somewhat  smooth  and  shining.  The  leaf  is  in  quality  poor,  coarse 
and  flimsy,  and  it  hangs — a web  of  shoddy — on  its  strong  supporting  ribs; 
lucky  for  it  that  its  edges  are  slightly  notched  and  much  ruffled,  else  they 
would  be  torn  and  tattered.  The  petiole  and  stems  are  felty  in  texture; 
the  petiole  is  grooved,  and  expands  at  its  base  to  grasp  the  stems  on  both 
sides  with  a certain  vicious  pertinacity  which  characterizes  the  whole 
plant. 

The  flower-heads  come  off  at  the  axils  of  the  upper  leaves,  and  are 
often  so  crowded  that  the  leaf  is  almost  lost  to  sight.  It  is  amazing  to 
behold  the  number  of  flower-heads  which  develop  on  one  thrifty  plant. 
The  main  stem  and  the  pyramid  of  lower  branching  stems,  are  often 
crowded  with  the  green  balls  beset  with  bracts  which  are  hooked,  spiny, 
and  which  hold  safe  the  flowers.  This  composite  flower-house  is  a 
fortress  bristling  with  spears  which  are  not  changed  to  peaceful  pruning- 
hooks,  although  they  are  hooked  at  the  sharp  end,  every  hook  turning 
toward  the  flowers  at  the  center ; the  lower  bracts  are  shorter  and  stand 
out  at  right  angles,  while  the  others  come  off  at  lesser  angles,  graded  so  as 
to  form  a globular  involucre — a veritable  block-house.  The  flower  might 
be  a tidbit  for  the  grazing  animal;  but,  if  so,  he  has  never  discovered  it, 
for  these  protective  hooks  have  kept  him  from  ever  enjoying  a taste. 
The  bracts  protect,  not  only  by  hooks  at  the  tip,  but  by  spreading  out  at 
the  bases  so  as  to  make  a thickly  battened  dwelling  for 
the  flower-family. 

But  if  we  tear  open  one  of  these  little  fortresses,  we  are 
well  repaid  in  seeing  the  quite  pretty  florets.  The  corol- 
las are  long,  slender,  pink  tubes,  with  five,  pointed  lobes. 
The  anther-tubes  are  purple,  the  pistils  and  the  stigmas 
white;  the  stigmas  are  broad  and  feathery  when  they 
are  dusting  out  the  pollen  from  the  anther-tubes,  but 
later  they  change  to  very  delicate  pairs  of  curly  Y’s. 
The  young  seed  is  shining  white,  and  the  pappus  forms  a 
short,  white  fluff  at  the  upper  margin ; but  this  is  simply 
a family  trait,  for  the  burdock  seeds  never  need  to  be 
ballooned  to  their  destination ; they  have  a surer  method 
oi  travel.  When  in  full  bloom,  the  burdock  flower-

heads  are  very  pretty  and  the  skillful  child  weaver  makes  them  into 
beautiful  baskets.  When  I was  a small  girl,  I made  whole  sets  of 
furniture  from  these  flowers ; and  then,  becoming  more  ambitious,  wove 
some  into  a coronet  which  I wore  proudly  for  a few  short  hours,  only  to 
discover  later,  from  my  own  experience,  that  great  truth  which  Shake- 
speare voiced, — “uneasy  lies  the  head  that  wears  the  crown.” 

In  winter,  the  tough,  gray  stalks  of  the  burdock  still  stand;  although 
they  may  partially  break,  if  they  can  thus  better  accomplish  their  pur- 
pose,— always  falling  toward  the  path.  In  this  way,  they  may  be  sure  of 
inserting  the  hooks  of  their  seed  storehouses  into  the  clothing  or  covering 
of  the  passer-by;  and  when  one  gets  a hold,  mayhap  a dozen  others  will 
hold  hands  and  follow.  If  they  catch  the  tail  of  horse  or  cow,  then  indeed 
they  must  feel  their  destiny  fulfilled ; for  the  animal,  switching  about  with 
its  uneasy  appendage,  threshes  out  the  seeds,  and  unheedingly  plants 
them  by  trampling  them  into  the  ground.  Probably  some  of  the  live- 
stock of  our  Pilgrim  Fathers  came  to  America  thus  burdened;  for  the 
burdock  is  a European  weed,  although  now  it  flourishes  too  successfully 
in  America.  The  leaves  of  the  burdock  are  bitter,  and  are  avoided  by 
grazing  animals.  Fortunately  for  us,  certain  flies  and  other  insects  like 
their  bitter  taste,  and  lay  eggs  upon  them,  which  hatch  into  larvae  that 
live  all  their  lives  between  the  upper  and  lower  surfaces  of  the  leaf.  Often 
the  leaves  are  entirely  destroyed  by  the  minute  larvae  of  a fly,  which  live 
together  cozily  between  these,  leaf  blankets,  giving  the  leaves  the  appear- 
ance of  being  afflicted  with  large  blisters. 

The  burdocks  have  long  vigorous  taproots,  and  it  is  therefore  difficult 
to  eradicate  them  without  much  labor.  But  persistent  cutting  off  the 
plant  at  the  root  will,  if  the  cut  be  deep,  finally  discourage  this  determined 
weed.

LESSON  CXLI 
The  Burdock 

Leading  thought — The  burdock  wins  because  its  great  leaves  shade 
down  plants  in  its  vicinity,  and  also  by  having  taproots.  It  scatters  its 
seed  by  hooking  its  seed-heads  fast  to  the  passer-by. 

Method — Study  a healthy 
burdock  plant  in  the  field,  to 
show  how  it  shades  down  other 
plants  and  does  not  shade  itself. 
The  flowers  and  the  seed-heads 
may  be  brought  into  the  school- 
room for  detailed  study. 

Observations — i.  Note  a 

young  plant.  How  much  space 
does  its  leaves  cover?  Is  any- 
thing growing  beneath  them? 
How  are  its  leaves  arranged  to 
cover  so  much  space?  Of  what 
advantage  is  this  to  the  plant? 

2.  Study  the  full-grown 
plant.  How  are  the  lower  leaves 
arranged?  At  what  angles  to 
the  stalks  do  the  petioles  lie? 
Are  the  upper  leaves  as  large  as 
the  lower  ones?  Do  they  stand 
at  different  angles  to  the  stalk? 

3 . Study  the  arrangement  of 
leaves  on  a burdock  plant,  to 

Burdock  blossoming.  discover  how  it  manages  to  shade 

down  other  plants  with  its  leaves 
and  yet  does  not  let  its  own  upper  leaves  shade  those  below. 

4.  Study  a lower  and  an  upper  leaf.  What  is  the  general  shape? 
What  peculiarity  where  it  joins  the  petiole?  What  is  the  texture  of  the 
leaf  above  and  below?  The  color?  Describe  the  petiole  and  how  it  joins 
the  stem. 

5.  Where  do  the  flowers  appear  on  the  stem  ? Are  there  many  flow- 
ers developed?  Count  all  the  flower-heads  on  a thrifty  burdock. 

6.  The  burdock  has  its  flowers  gathered  into  families,  like  the  sun- 
flower and  thistle.  Describe  the  burdock  flower-family  according  to 
Lesson  CXXXV. 

7.  What  insects  visit  the  burdock  flowers?  Can  you  make  baskets 
from  the  flower-heads  ? 

8.  Study  the  burdock  again  in  winter,  and  see  what  has  happened  to 
it.  Describe  the  seed  and  the  seed-heads.  How  are  the  seed-heads 
carried  far  away  from  the  parent  plant?  How  many  seeds  in  a single 
"house?”  How  do  they  escape? 

9.  Write  the  biography  of  a burdock  plant  which  came  to  America  as 
a seed,  attached  to  the  tail  of  a Shetland  pony.

PRICKLY  LETTUCE,  A COMPASS  PLANT 


Teacher's  Story 


The  more  we  know  of  plants,  the  more  we  admire  their  ways  of  attain- 
ing success  in  a world  where  it  is  only  attained  by  a species  after  a long 
struggle.  While  plants  may  not  be  conscious  of  their  own  efforts  for 
living  on  successfully,  they  have  developed  them  just  the  same,  and  they 
merit  our  admiration  perhaps  even  more,  than  as  if  their  strategy  was  the 

result  of  conscious  thought. 
The  prickly  lettuce  has  a 
story  to  tell  us  about  suc- 
cess attained  by  the  pre- 
vention of  exhaustion  from 
thirst.  In  fact,  the  success 
of  this  weed  depends  much 
upon  its  being  able  to  live 
in  dry  situations  and  with- 
stand the  long  droughts  of 
late  summer.  The  pale 
green  stems  grow  up  slim 
and  tall,  bearing  leaves 
arranged  alternately  and 
from  all  sides,  since  be- 
tween two,  one  of  which  is 
exactly  above  the  other, 
two  other  leaves  are  borne. 
Thus,  if  the  leaves  stood  out 
naturally,  the  shape  of  the 
whole  plant  would  be  a 
somewhat  blunt  pyramids 
But  during  the  hot,  dry 
weather,  the  leaves  do  not 
stand  out  straight  from  the 
stem;  instead,  they  twist 
about  so  that  they  are 
practically  all  in  one  plane, 
and  usually  point  north 
and  south,  although  this  is 
not  invariably  the  case- 
The  way  this  twisting  is  accomplished  is  what  interests  us  in  this  plant. 
The  long  spatulate  leaf  has  a thick,  fleshy  midrib,  and  at  the  base  are 
developed  two  pointed  lobes  which  clasp  the  stalk.  The  leaf  is  soft  and 
leathery  and  always  seems  succulent,  because  it  retains  its  moisture;  it 
has  a ruffled  edge  near  its  base,  which  gives  it  room  for  turning  without 
tearing  its  margin.  Each  leaf  tips  over  sidewise  toward  the  stem,  and  as 
far  as  necessary  to  bring  one  edge  uppermost.  Thus  the  sun  cannot 
reach  its  upper  surface  to  pump  water  from  its  tissues.  The  ruffled 
margin  of  the  upper  edge  is  pulled  out  straight  when  the  leaf  stands 
in  this  position,  while  the  lower  margin  is  more  ruffled  than  ever.  Thus, 
it  stands  triumphantly,  turning  edgewise  to  the  sun,  retaining  its  moisture 
and  thriving  when  cultivated  plants  are  dry  and  dying.

It  also  has  another  “anchor  to  the  windward.”  A plant  so  full  of  juice 
would  prove  attractive  food  for  cattle  when  pastures  are  dry.  The  leaves 
of  this  perhaps  escape,  because  each  has  a row  of  very  sharp  spines  on  the 
lower  side  of  the  midrib.  At  first  we  might  wonder  why  they  are  thus 
placed ; but  if  we  watch  a grazing  animal,  as  a cow,  reach  out  her  tongue 
to  pull  the  herbage  into  her  mouth,  we  see  that  these  spines  are  placed 
where  they  will  do  the  most  efficient  work.  The  teasel  has  the  same 
clever  way  of  warning  off  meddlesome  tongues.  The  prickly  lettuce  also 
has  spines  on  its  stem,  and  the  leaves  are  toothed  with  spines  at  their 
points. 

LESSON  CXLII 
Prickly  Lettuce 

Leading  thought — The  sunshine  sets  the  machinery  in  the  leaf-factories 
going,  and  incidentally  pumps  up  water  from  the  soil,  which  pours  out 
into  the  air  from  the  leaves ; but  if  the  soil  is  dry  the  pump  works  just  the 
same,  and  the  plant  thus  robbed  of  its  water  soon  withers  and  dies.  The 
young  plants  of  wild  lettuce  prevent  the  sun  from  pumping  them  dry  dur- 
ing drought,  by  turning  the  edges  of  their  leaves  toward  the  sun,  and  thus 
not  exposing  the  leaf  surface  to  its  rays.  The  leaves  thus  lifted  stand  in 
one  plane.  They  are  usually  directed  north  and  south.  The  lettuce  also 
has  spines  to  protect  it  from  grazing  animals. 

Method — The  lettuce  should  be  studied  in  the  field,  and  is  a good  sub- 
ject for  a lesson  in  late  summer  or  September.  This  lesson  should  supple- 
ment the  one  on  transpiration.  The  young  plants  show  this  arrangement 
of  the  leaves  best.  The  flowers  may  be  studied  by  the  outline  given  in 
Lesson  CXXXV. 

Observations — 1 . Where  does  the  prickly  lettuce  grow?  What  sort  of 
a stem  has  it  ? How  are  the  leaves  arranged  on  the  stem  ? 

2.  If  the  leaves  stood  straight  out  from  the  stem,  what  would  be  the 
shape  of  the  plant?  How  do  the  leaves  stand?  Is  their  upper  surface 
exposed  to  the  rays  of  the  sun?  Which  portion  of  the  leaf  is  turned 
toward  the  sun  ? 

3.  If  the  leaves  turn  sideways  and  stand  in  one  plane,  do  they  stand 
north  and  south  or  east  and  west.  How  does  the  edgewise  position  of  the 
leaf  protect  the  plant  during  drought  ? Why  does  any  plant  wither  dur- 
ing drought?  If  the  leaves  of  the  lettuce  should  extend  east  and  west 
instead  of  north  and  south,  would  they  get  more  sun  ? (See  lesson  on  the 
Sun.) 

4.  . What  is  the  shape  of  the  lettuce  leaf?  How  does  it  clasp  the  stalk  ? 
How  is  the  base  shaped  so  that  the  leaf  can  turn  without  tearing  its 
edges?  Sketch  a leaf  thus  turned  fully,  showing  how  it  is  done.  Does 
the  leaf  turn  toward  the  stem  or  away  from  it  ? 

5.  How  are  the  leaves  protected  against  grazing  cattle?  How  does 
the  cow  use  her  tongue  to  help  bring  herbage  to  her  mouth  ? How  are  the 
prickly  spines  placed  on  the  lettuce  leaf,  to  make  the  cow’s  tongue  un- 
comfortable? Sketch  a leaf  showing  its  shape,  its  venation  and  its 
spines.

THE  DANDELION 
Teacher's  Story 

HIS  is  the  most  persistent  and  indomitable 
of  weeds,  yet  I think  the  world  would  be 
very  lonesome  without  its  golden  flower- 
heads  and  fluffy  seed-spheres.  Professor 
Bailey  once  said  that  dandelions  in  his  lawn 
were  a great  trouble  to  him  until  he  learned 
to  love  them,  and  then  the  sight  of  them 
gave  him  keenest  pleasure.  And  Lowell 
says  of  this  “dear  common  flower” — 


“ Tis  Spring's  largess,  which  she  scatters  now 
To  rich  and  poor  alike,  with  lavish  hand; 

Though  most  hearts  never  understand 
To  take  it  at  God's  value,  and  pass  by 
The  offered  wealth  with  unrewarded  eye." 

It  is  very  difficult  for  us,  when  we  watch  the  behavior  of  the  dandelions, 
not  to  attribute  to  them  thinking  power,  they  have  so  many  ways  of 
getting  ahead  of  us.  I always  look  at  a dandelion  and  talk  to  it  as  if  it 
were  a real  person.  One  spring  when  all  the  vegetables  in  my  garden 
were  callow  weaklings,  I found  there,  in  their  midst,  a dandelion  rosette 
with  ten  great  leaves  spreading  out  and  completely  shading  a circle  ten 
inches  in  diameter;  I said,  “Look  here,  Madam,  this  is  my  garden!”  and  I 
pulled  up  the  squatter.  But  I could  not  help  paying  admiring  tribute  to 
the  taproot,  which  lacked  only  an  inch  of  being  a foot  in  length.  It 
was  smooth,  whitish,  fleshy  and,  when  cut,  bled  a milky  juice  showing 
that  it  was  full  of  food ; and  it  was  as  strong  from  the  end-pull  as  a whip- 
cord ; it  also  had  a bunch  of  rather  fine  rootlets  about  an  inch  below  the 
surface  of  the  soil  and  an  occasional  rootlet  farther  down ; and  then  I said 
“Madam,  I beg  your  pardon ; I think  this  was  your  garden  and  not  mine.” 

Dandelion  leaves  afford  an  excellent  study  in  variation  of  form.  The 
edges  of  the  leaf  are  notched  in  a peculiar  way,  so  that  the  lobes  were,  by 
some  one,  supposed  to  look  like  lions’  teeth  in  profile ; thus  the  plant  was 
called  in  France  “dents-de-lion”  (teeth  of  the  lion),  and  we  have  made 
from  this  the  name  dandelion.  The  leaves  are  so  bitter  that  grazing 
animals  do  not  like  to  eat  them,  and  thus  the  plants  are  safe  even  in 
pastures. 

The  hollow  stem  of  the  blossom-head  from  time  immemorial  has  been 
a joy  to  children.  It  may  be  made  into  a trombone,  which  will  give  to  the 
enterprising  teacher  an  opportunity  for  a lesson  in  the  physics  of  sound, 
since  by  varying  its  length,  the  pitch  is  varied.  The  dandelion-curls, 
which  the  little  girls  enjoy  making,  offer  another  lesson  in  physics — that  of 
surface  tension,  too  difficult  for  little  girls  to  understand.  But  the  action 
of  this  flower  stem  is  what  makes  the  dandelion  seem  so  endowed  with 
acumen.  ■ If  the  plant  is  in  a lawn,  the  stem  is  short,  indeed  so  short  that 
the  lawn-mower  cannot  cut  off  the  flower-head.  In  this  situation  it  will 
blossom  and  seed  within  two  inches  of  the  ground ; but  if  the  plant  is  in  a 
meadow  or  in  other  high  grass,  the  stem  lifts  up  sometimes  two  feet  or 
more,  so  that  its  blossom  may  be  seen  by  bees  and  its  seeds  be  carried  off 
by  the  breeze  without  let  or  hindrance  from  the  grass.  We  found  two 
such  stems  each  measuring  over  30  inches  in  height. 


Wild -Flower  Study 


573 


Before  a dandelion  head  opens,  the  stem,  umess  very  short,  is  likely  to 
bend  down  to  protect  the  young  flowers,  but  the  night  before  it  is  to  bloom 
it  straightens  up;  after  the  blossoms  have  matured  it  may  again  bend 
over,  but  straightens  up  when  the  seeds  are  to  be  cast  off. 

It  often  requires  an  hour  for  a dandelion  head  to  open  in  the  morning 
and  it  rarely  stays  open  longer  than  five  or  six  hours;  it  may  require 
another  hour  to  close.  Usually  not  more  than  half  the  flowers  of  the  head 
open  the  first  day,  and  it  may  require  several  days  for  them  all  to  blossom. 
After  they  have  all  bloomed  and  retired  into  their  green  house  and  put  up 
the  shutters,  it  may  take  them  from  one  to  two  weeks  to  perfect  their 
seeds. 

In  the  life  of  the  flower-head  the  involucre,  or  the  house  in  which  the 
flower  family  lives,  plays  an  important  part.  The  involucral  bracts,  in 
the  row  set  next  to  the  flowers,  are  sufficiently  long  to  cover  the  unopened 
flowers;  the  bracts  near  the  stem  are  shorter  and  curl  back,  making  a 
frill.  In  the  freshly  opened  flower-head,  the  buds  at  the  middle  all  curve 
slightly  toward  the  center,  each  bud  showing  a blunt,  five-lobed  tip  which 
looks  like  the  tips  of  five  fingers  held  tightly  together.  The  flowers  in  the 
outer  row  blossom  first,  straightening  back  and  pushing  the  banner  out- 
ward ; and  now  we  can  see  that  the  five  lobes  in  the  bud  are  the  five 
^ notches  at  the  end  of  the  banner.  All  the  flowers  in  the  dandelion-head 
have  banners,  but  those  at  the  center,  belonging  to  the  younger  flowers, 
have  shorter  and  darker  yellow  banners.  After  a banner  is  unfurled, 
there  pushes  out  from  its  tubular  base  a darker  yellow  anther-tube ; the 
five  filaments  below  the  tube  are  visible  with  a lens.  A little  later,  the 
stigma-ramrod  pushes  forth  from  the  tube,  its  fuzzy  sides  acting  like  a 
brush  to  bring  out  all  the  pollen ; later  it  rises  far  above  the  anther-tube 
and  quirls  back  its  stigma-lobes,  as  if  every  floret  were  making  a dande- 
lion curl  of  its  own.  The  lens  shows  us,  below  the  corolla,  the  seed.  The 
pappus  is  not  set  in  a collar  upon  the  dandelion  seed,  as  it  is  in  the  aster 
seed;  there  is  a short  stem  above  the  seed  which  is  called  the  “beak”  and 
the  pappus  is  attached  to  this. 

Every  day  more  blossoms  open ; but  on  dark,  rainy  days  and  during 
the  night  the  little  green  house  puts  up  its  shutters  around  the  flower- 
family,  and  if  the  bracts  are  not  wide  enough  to  cover  the  growing 
family,  the  banners  of  the  outer  flowers  have  thick  or  brownish  portions 
along  their  lower  sides  which  serve  to  calk  the  chinks.  It  is  interesting  to 
watch  the  dandelion  stars  close  as  the  night  falls,  and  still  more  interesting 
to  watch  the  sleepy-heads  awaken  long  after  the  sun  is  up  in  the  morning; 
they  often  do  not  open  until  eight  o’clock.  The  dandelion  flower-families 
are  very  economical  of  their  pollen  and  profuse  nectar,  and  do  not  expose 
them  until  the  bees  and  other  insects  are  abroad  ready  to  make  morning 
calls. 

After  all  the  florets  of  a dandelion  family  have  blossomed,  they  retire 
again  into  their  green  house  and  devote  themselves  to  perfecting  their 
seeds.  They  may  stay  thus  in  retirement  for  several  days,  and  during 
this  period  the  flower  stem  often  grows  industriously ; and  when  the 
shutters  of  the  little  green  house  are  again  let  down,  what  a different 
appearance  has  the  dandelion  family ! The  seeds  with  their  balloons  are 
set  so  as  to  make  an  exquisite,  filmy  globe;  and  now  they  are  ready  to 
coquette  with  the  wind  and,  one  after  another,  all  the  balloons  go  sailing 
off.  One  of  these  seeds  is  well  worth  careful  observation  through  a lens.

The  balloon  is  attached  to  the  top  of  the  beak  as  an  umbrella  frame  is 
attached  to  the  handle,  except  that  the  “ribs”  are  many  and  fluffy;  while 
the  dandelion  youngster,  hanging  below,  has  an  overcoat  armed  with 
grappling  hooks,  which  enable  it  to  cling  fast  when  the  balloon  chances  to 
settle  to  the  ground.

dandelion.  Both  enlarged. 


Father  Tabb  says  of  the  dandelion, — • 
“With  locks  of  gold  today;  tomorrow 
silver  gray;  then  blossom  bald.”  But 
not  the  least  beautiful  part  of  the  dande- 
lion is  this  blossom-bald  head  after  all 
the  seeds  are  gone;  it  is  like  a mosaic, 
with  a pit  at  the  center  of  each  figure 
where  the  seed  was  attached.  There  is 
an  interesting  mechanism  connected 
with  this  receptacle.  Before  the  seeds 
are  fully  out  this  soon-to-be-bald  head 
Is  concave  at  the  center,  later  it  becomes 
convex,  and  the  mechanism  of  this  move- 
ment liberates  the  seeds  which  are  em- 
bedded in  it. 

Each  freshly  opened  corolla-tube  is 
full  to  overflowing  with  nectar,  and  much* 
pollen  is  developed ; therefore,  the  dandelion  has  many  kinds  of  insect 
visitors.  But  perhaps  the  bee  shows  us  best  where  the  nectar  is 
found;  she  thrusts  her  tongue  down  into  the  little  tubes  below  the 
banners,  working  very  rapidly  from  floret  to  floret.  The  dandelion 
stigmas  have  a special  provision  for.  securing  cross-pollenation ; and  if 
that  fails,  to  secure  pollen  from  their  own  flower-family;  and  now  the 
savants  have  found  that  the  pistils  can  also  grow  seeds  without  any  pollen 
from  anywhere.  It  surely  is  a resourceful  plant! 

The  following  are  the  tactics  by  which  the  dandelion  conquers  us  and 
takes  possession  of  our  lands:  (a)  It  blossoms  early  in  the  spring  and 

until  snow  falls,  producing  seed  for  a long  season,  (b)  It  is  broad- 
minded as  to  its  location,  and  flourishes  on  all  sorts  of  soils,  (c)  It  thrusts 
its  long  tap-roots  down  into  the  soil,  and  thus  gets  moisture  and  food  not 
reached  by  other  plants,  (d)  Its  leaves  spread  out  from  the  base,  and 
crowd  and  shade  many  neighboring  plants  out  of  existence,  (e)  It  is  on 
good  terms  with  many  insects,  and  so  has  plenty  of  pollen  carriers  to 
insure  strong  seeds ; it  can  also  develop  seeds  from  its  own  pollen,  and  as  a 
last  resort  it  can  develop  seeds  without  any  pollen,  (f)  It  develops 
almost  numberless  seeds,  and  the  wind  scatters  them  far  and  wide  and 
they  thus  take  possession  of  new  territory,  (g)  It  forms  vigorous  leaf- 
rosettes  in  the  fall,  and  thus  is  able  to  begin  growth  early  in  the  spring. 


LESSON  CXLIII 
The  Dandelion 

Leading  thought — The  dandelions  flourish  despite  our  determined 
efforts  to  exterminate  them.  Let  us  study  the  way  in  which  they 
conquer. 

Method — The  study  should  be  made  with  the  dandelions  on  the  school 
grounds.  Questions  should  be  given,  a few  at  a time,  and  then  let  the 
pupils  consult  the  dandelions  as  to  the  answers.

The  dandelion  is  a composite  flower  and  may  be  studied  according  to 
Lesson  CXXXV.  All  the  florets  have  banners  or  rays. 

Observations  i.  Where  do  you  find  dandelions  growing?  If  they 
are  on  the  lawn,  how  long  are  their  blossom  or  seed  stems  ? If  in  a meadow 
or  among  high  grass,  how  long  is  the  blossom  stem  ? Why  is  this  ? Is  the 
blossom  stem  solid  or  hollow  ? Does  it  break  easily  ? 

2.  Dig  up  a dandelion  root  and  then  explain  why  this  weed  with- 
stands drought,  and  why  it  remains,  when  once  planted. 

3.  Sketch  or  describe  a dandelion  leaf.  Why  was  the  plant  named 
“lion's  teeth?”  How  are  the  leaves  arranged  about  the  root?  How 
does  this  help  the  dandelion  and  hinder  other  plants?  In  what  condition 
do  the  leaves  pass  the  winter  under  the  snow?  Why  is  this  useful  to  the 
plant  ? 

4.  Take  a blossom  not  yet  open.  Note  the  bracts  that  cover  the 
unopened  flower-head.  Note  the  ones  below  and  describe  them. 

5.  Note  the  dandelion  flower-head  just  open.  Which  flowers  open 
first?  How  do  the  buds  look  at  the  center?  Do  all  the  florets  have 
banners?  Are  the  banners  of  the  central  florets  the  same  color  and 
length  as  of  those  outside?  Examine  a floret  and  note  the  young  seed. 
Is  the  pappus  attached  to  it  or  above  it? 

6.  What  happens  to  the  dandelion  blossom  on  rainy  or  dark  days? 
How  is  the  dandelion  family  hidden  during  the  rain?  When  does  it  ap- 
pear again  ? Do  you  think  that  this  has  anything  to  do  with  the  insect 
visitors?  Do  bees  and  other  insects  gather  nectar  during  dark  or  rainy 
days? 

7.  Note  at  what  hour  the  dandelions  on  the  lawn  go  to  sleep  and  at 
what  hour  they  awaken  on  pleasant  days? 

8.  Make  notes  on  a certain  dandelion  plant  three  times  a day : How 

long  does  it  take  the  dandelion  head  to  open  fully  on  a sunny  morning? 
How  long  does  it  remain  open?  How  long  does  it  take  the  flower-head  to 
close?  What  proportion  of  the  flowers  in  the  head,  blossoms  during  the 
first  day  ? What  proportion  of  the  flowers  in  the  head,  blossoms  during  the 
second  day?  How  long  before  they  all  blossom?  Does  the  flower-head 
remain  open  longer  in  the  afternoon  on  some  days  than  on  others,  equally 
sunny?  Does  ihe  stem  bend  over  before  the  blossom-head  opens? 

9.  After  all  the  little  flowers  of  a dandelion  family  have  blossomed, 
what  happens  to  it?  How  long  does  it  stay  shut  up  in  its  house?  Meas- 
ure the  stem,  and  see  if  it  stretches  up  during  the  time.  How  does  the 
dandelion  look  when  it  opens  again?  Look  at  a dandelion-head  full  of 
seed,  and  see  how  the  seeds  are  arranged  to  make  a perfect  globe.  Shake 
the  seeds  off  and  examine  the  “bald  head”  with  a lens.  Can  you  see 
where  the  seeds  were  set? 

10.  Examine  a dandelion  seed  with  a lens.  Describe  the  balloon,  the 
beak  or  stem  of  the  balloon,  and  the  seed.  Why  do  you  suppc:e  the  seed 
has  these  hooks  ? 

1 1 . How  early  in  the  spring,  and  how  late  in  the  fall,  do  dandelions 
blossom  ? 

12.  Watch  a bee  when  she  is  working  on  a dandelion  flower,  and  see 
where  she  thrusts  her  tongue  and  which  flowers  she  probes. 

13.  Tell  all  the  things  that  you  can  remember  which  the  dandelion 
does  in  order  to  live  and  thrive  in  spite  of  us. 

14.  What  use  do  we  make  of  the  dandelions?

THE  PEARLY  EVERLASTING 


Teacher's  Story 


These  wraithlike  flowers  seem  never  to  have  been  alive,  rather  than  to 
have  been  endowed  with  everlasting  life.  The  cattle  share  this  opinion 
and  would  no  sooner  eat  these  plants  than  if  they  were  made  of  cotton 
batting.  The  stems  are  covered  with  white  felt ; the  long  narrow  leaves 

are  very  pale  green,  and 
when  examined  with  a 
lens,  look  as  if  they 
were  covered  with  a 
layer  of  cotton  which 
disguises  all  venation 
except  the  thick  mid- 
rib. The  leaves  are  set 
alternate,  and  become 
shorter  and  narrower 
and  whiter  toward  the 
top  of  the  plant,  where 
they  are  obliged  to  give 
their  sustenance  to  the 
flower  stems  borne  in 
their  axils.  All  this 
cottony  covering  has 
its  uses  to  prevent  the 
evaporation  of  water 
from  the  plant  during 
the  long  droughts.  The 
everlasting  never  has 
much  juice  in  its  leaves 
but  what  it  has,  it 
keeps. 

The  flower  stems  are 
rather  stout,  woolly, 
soft  and  pliable.  They 
come  off  at  the  axils  of 
the  threadlike  whitish 
leaves.  The  pistillate 
and  the  staminate  flow- 
ers are  borne  on  separ- 
ate plants,  and  usually 
in  separate  patches. 
The  pistillate,  or  seed- 
developing,  plants  have

almost  egg-shaped,  with

mas  split  at  the  end. 

At  the  center  of  this  tassel  of  lemon-yellow  stigma-plush,  may  often  be 
seen  a depression;  at  the  bottom  of  this  well,  there  are  three  or  four

perfect  flowers.  One  of  the  secrets  of  the  everlasting  is,  evidently,  that  it 
does  not  put  all  of  its  eggs  in  one  basket ; it  has  a few  perfect  flowers  for 
insurance.  This  pistillate  or  seed-bearing  flower  has  a long,  delicate 
tube,  ending  in  five  needlelike  points  and  surrounded  by  a pretty  pappus. 

The  bracts  of  the  flower-cluster  seem  to  cling 
around  the  base  of  the  beautiful  yellow  tassel  of 
fertile  flowers,  as  if  to  emphasize  it.  They  look 
as  if  they  were  made  of  white  Japanese  paper, 
and  when  looked  at  through  a lens,  they  resemble 
the  petals  of  a water  lily  They  are  dry  to  begin 
with,  so  they  cannot  wither. 

The  staminate,  or  pollen-bearing,  flower-heads 
are  like  white  birds’  nests,  the  white  bracts  form- 
ing the  nest  and  the  little  yellow  flowers  the  eggs. 
The  flower  has  a tubular,  five-pointed  starlike 
corolla,  with  five  stamens  joined  in  a tube  at  the 
middle,  standing  up  like  a barrel  from  the  corolla. 
The  anther-tube  is  ocher-yellow  with  brown 
stripes,  and  is  closed  at  first  with  five  little  flaps, 
making  a cone  at  the  top.  Later,  the  orange-yellow  pollen  bulges  out  as 
if  it  were  boiling  over.  The  flowers  around  the  edges  of  the  flower-disk 
open  first. 

LESSON  CXLIV 
The  Pearly  Ever- 
lasting 

Leading  thought — 

There  are  often  found 
growing  on  the  poor 
soil  in  dry  pastures, 
clumps  of  soft,  whitish 
plants  which  are  never 
eaten  by  cattle.  There 
is  so  little  juice  in 
them  that  they  retain 
their  form  when  dried 
and  thus  have  won 
their  name. 

Meth  od — The  pu-  , 
pils  should  see  these 
plants  growing,  so  that 
they  may  observe  the 
staminate  and  pistil- 
late flowers,  which 
are  on  separate  plants 
and  in  separate 
clumps.  If  this  is 
not  practicable,  bring 
both  kinds  of  flowers 
into  the  schoolroom 

for  study.  The  laminate  flower-head  of  pearly  everlasting.

Observations — i.  Where  does  the  pearly  everlasting  grow?  Do  cattle 
eat  it  ? Why  is  this  ? What  is  the  general  color  of  the  plant  ? What 
is  the  stem  covered  with? 

2.  What  is  the  shape  of  the  leaves?  How  are  they  veined?  With 
what  are  they  covered?  How  are  they  placed  on  the  stem?  What  is  the 
relative  size  of  the  lower  and  upper  leaves?  Why  is  there  a difference? 

3.  Do  you  see  some  plants  which  have  egg-shaped  blossoms,  each 
with  a yellow  knob  at  the  tip?  Take  one  apart  and  look  at  it  with  a 
lens,  and  see  what  iforms  the  white  part  and  what  forms  the  yellow 
knob.  Do  you  see  other  flowers  that  look  like  little  white  birds’  nests 
filled  with  yellow  eggs?  Look  at  one  of  them  with  a lens,  and  tell  what 
kind  of  a flower  it  is. 

4.  Except  that  the  pistillate  and  staminate  flowers  are  on  different 
plants,  the  flowers  of  the  pearly  everlasting  should  be  studied  according 
to  Lesson  CXXXV. 

5.  What  do  you  know  of  the  edelweiss  of  the  Alps?  How  does  it 
resemble  the  pearly  everlasting?  Do  you  know  another  common  kind  of 
everlasting  called  pussy’s  toes? 


THE  JEWELWEED,  OR  TOUCH-ME-NOT 
Teacher's  Story 

“ Cup  bearer  to  the  summer,  this  floral  Hebe  shy 
Is  loitering  by  the  brookside  as  the  season  passes  by; 

And  she's  strung  her  golden  ewers  with  spots  of  brown  all  flecked, 
O'er  dainty  emerald  garments,  like  a queen  with  gems  bedecked. 


She  brooks  not  condescension  from  mortal  hand, 
you  know, 

For,  touch  her  e'er  so  gently,  impatiently 
she'll  throw 

^Her  tiny  little  jewels,  concealed  in  pockets 
small 

Of  her  dainty,  graceful  garment,  and  o'er  the 
ground  they  fall. ' ' 

— Ray  Laurance 


EWELS  for  the  asking  at  the  brookside, 
pendant  jewels  of  pale-gold  or  red-gold  and 
of  strange  design ! And  the  pale  and  the 
red  are  different  in  design,  although  of  the 
same  general  pattern.  The  pale  ones  seem 
more  simple  and  open,  and  we  may  study  them 
first.  If  the  flowers  of  the  jewelweed  have  been 
likened  to  ladies’  earrings,  then  the  bud  must 
be  likened  to  the  old-fashioned  ear-bob ; for  it  is 
done  up  in  the  neatest  little  triangular  knob 
imaginable,  with  a little  curly  pig-tail  appendage 
at  one  side,  and  protected  above  by  two  cup- 
shaped sepals,  their  pale  green  seeming  like  ena- 
mel on  the  pale  gold  of  the  bud.  It  is  worth 
while  to  give  a glance  at  the  stem  from  which 


Wild -Flower  Study 


579 


this  jewel  hangs ; it  is  so  delicate  and  so  gracefully  curved ; and  just  above 
the  twin  sepals  is  a tiny  green  bract,  elongate,  and  following  the  curve  of 
the  stem  as  if  it  were  just  a last  artistic  touch;  and  though  the  flowers 
fall,  this  little  bract  remains  to  keep  guard  above  the  seed-pod. 

It  would  take  a Yankee,  very  "good  at  guessing,  to  make  out  the  parts 
of  this  flower,  so  strange  are  they  in  form.  We  had  best  begin  by  looking 
at  the  blossom  from  the  back  side.  The  two  little,  greenish  sepals  are 
lifted  back  like  butterfly  wings,  and  we  may  guess  from  their  position  that 
there  are  two  more  sepals,  making  four  in  all.  These  latter  are  yellow; 
one  is  notched  at  the  tip  and  is  lifted  above  the  flower;  the  other  is  below 
and  is  made  into  a wide-mouthed  triangular  sac,  ending  in  a quirl  at  the 
bottom,  which,  if  we  test  it,  we  shall  find  is  the  nectary,  very  full  of 
sweetness.  Now,  if  we  look  the  flower  in  the  face,  perhaps  we  can  find 
the  petals;  there  are  two  of  them  “holding  arms”  around  the  mouth  of 
the  nectar-sac.  And  stiff  arms  they  are  too,  two  on  a side,  for  each  petal 
is  two-lobed,  the  front  lobe  being  very  short  and  the  posterior  lobe 
widening  out  below  into  a long  frill,  very  convenient  for  the  bee  to  cling 
to,  if  she  has  learned  the  trick,  when  prospecting  the  nectar-sac  behind 
for  its  treasure.  The  way  this  treasure-sac  swings  backward  from  its 
point  of  attachment  above  when  the  insect  is  probing  it,  must  make  the 
lady  bee  feel  that  the  joys  of  life  are  elusive.  Meanwhile,  what  is  the 
knob  projecting  down  above  the  entrance  to  the  nectar-sac,  as  if  it  were  a 
chandelier  in  a vestibule  ? If  we  look  at  it  with  a lens,  we  can  see  that  it  is 
made  up  of  five  chubby  anthers,  two  in  front,  one  at  each  side  and  one 
behind;  their  short,  stout  little  filaments  are  crooked  just  right  to  bring 
the  anthers  together  like  five  closed  fingers  holding  a fist  full  of  pollen-dust, 
just  ready  to  sift  it  on  the  first  one  that  chances  to  pass  below.  Thus  it  is 
that  Madame  Bumblebee,  who  dearly  loves  the  nectar  from  these  flowers, 
gets  her  back  well  dusted  with  the  creamy-white  pollen  and  does  a great 
business  for  the  jewelweed  in  transferring  it.  But  after  the  pollen  is  shed, 
some  day  the  bumblebee  pushes  up  too  hard  against  the  anthers  and  they 
break  loose,  all  in  a bunch,  looking  like  a crooked  legged  table;  and 
there  in  their  stead,  thus  left  bare  and  ready  for  pollen,  is  the  long  green 
pistil  with  its  pointed  stigma  ready  to  rake  the  pollen  out  of  the  fur  of  any 
bumblebee  that  calls. 

The  red-gold  jewelweed  is  quite  different  in  shape  from  the  pale 
species.  The  sepal-sac  is  not  nearly  so  flaring  at  the  mouth,  and  the 
nectar-spur  is  half  as  long  as  the  sac  and  curves  and  curls  under  in  a most 
secretive  fashion.  The  shape  of  the  nectar-spur  suggests  that  it  was 
meant  for  an  insect  with  a long,  flexible  sucking  tube  that  could  curl 
around  and  probe  it  to  the  bottom;  and  some  butterflies  do  avail  them- 
selves of  the  contents  of  this  bronze  pitcher.  Mr.  Mathews  mentions  the 
Papilio  troilus,  and  I have  seen  the  yellow  roadside  butterfly  partaking 
of  the  nectar.  Professor  Robertson  believes  that  the  form  of  the  nectar- 
spur  is  especially  adapted  for  the  hummingbird.  But  I am  sure  that  the 
flowers  which  I have  had  under  observation  are  the  special  partners  of  a 
small  species  of  bumblebee,  which  visits  these  flowers  with  avidity, 
celerity, and  certainty,  plunging  into  the  nectar-sac  “like  a shot, ’’and  out 
again  and  in  again  so  rapidly  that  the  eye  can  hardly  follow.  One  day, 
one  of  them  accommodatingly  alighted  on  a leaf  near  me,  while  she 
combed  from  her  fur  a creamy-white  mass  of  pollen,  which  matched  in 
color  the  fuzz  on  her  back,  heaping  it  on  her  leg  baskets.  She  seemed  to 


580 


Handbook  of  N atur e-Study 


know  that  the  pollen  was  on  her  back,  and  it  was  comical  to  see  her 
contortions  to  get  it  off.  The  action  of  these  bumblebees  in  these  flowers 
is  in  marked  contrast  to  those  of  the  large  bumblebees  and  the  honey- 
bees. One  medium-sized  species  of  bumblebee  has  learned  the  trick  of 
embracing  with  the  front  legs  the  narrow,  stiff  portion  of  the  petals  which 
encircles  the  opening  to  the  sac,  thus  holding  the  flower  firm  while 
thrusting  the  head  into  the  sac.  While  the  huge  species — black  with  very 
yellow  plush — does  not  attempt  to  get  the  nectar  in  a legitimate  manner, 
but  systematically  alights,  back  downward,  below  the  sac  of  the  flower, 
with  head  toward  the  curved  spur,  and  cuts  open  the  sac  for  the  nectar. 
A nectar-robber  of  the  most  pronounced  type ! The  honey-bees,  Italian 
hybrids,  are  the  most  awkward  in  their  attempts  to  get  nectar  from  these 
flowers;  they  attempt  to  alight  on  the  expanded  portion  of  the  petals  and 
almost  invariably  slide  off  between  the  two  petals.  They  then  circle 
around  and  take  observations  with  a note  of  determination  in  their 
buzzing,  and  finally  succeed,  as  a rule,  in  gaining  a foothold  and  securing 
the  nectar.  But  the  midget  bumblebees  show  a savoir  faire  in  probing 
the  orange  jewelweed  that  is  convincing;  they  are  so  small  that  they  are 
quite  out  of  sight  when  in  the  nectar-sacs. 

The  jewelweed  flowers  of  the  pale  species  and  the  pale  flowers  of  the 
orange  species — for  this  latter  has  sometimes  pale  yellow  flowers — are  not 
invariably  marked  with  freckles  in  the  nectar-sac.  But  the  most  common 
forms  are  thus  speckled.  There  is  something  particularly  seductive  to 
insects  in  these  brownish  or  reddish  flecks,  and  wherever  we  find  them  in 
flowers,  we  may  with  some  confidence  watch  for  the  insects  they  were 
meant  to  allure.  The  orange  jewelweed  flower  is  a model  for  an  artist  in 
its  strange,  graceful  form  and  its  color  combination  of  yellow  spotted  and 
marbled  with  red. 

Gray’s  Manual  states  that  in  the  jewelweeds  are  often  flowers  of  two 
sorts  “The  large  ones  which  seldom  ripen  seeds,  and  very  small  ones 
which  are  fertilized  early  in  the  bud,  their  floral  envelopes  never  expand- 
ing but  forced  off  by  the  growing  pod  and  carried  upward  on  its  apex.” 
My  jewelweed  patch  has  not  given  me  the  pleasure  of  observing  these  two 
kinds  of  flowers;  my  plants  blossom  luxuriously  and  profusely,  and  a 
large  proportion  of  the  flowers  develop  seed.  The  little,  straight,  elon- 
gated seed-pods  are  striped  prettily  and  become  quite  plump  from  the 
large  seeds  within  them.  Impatiens?  We  should  say  so!  This  pod 
which  looks  so  smug  and  straight-laced  that  we  should  never  suspect  it  of 
being  so  touchy,  at  the  slightest  jar  when  it  is  ripe,  splits  lengthwise  into 
five  ribbon-like  parts,  all  of  which  tear  loose  at  the  lower  end  and  fly  up 
in  spirals  around  what  was  once  the  tip  of  the  pod,  but  which  now  looks 
like  a crazy  little  turbine  wheel  with  five  arms.  And  meanwhile,  through 
this  act  the  fat,  wrinkled  seeds  have  been  flung,  perhaps  several  feet  away 
from  the  parent  plant,  and  presumably  to  some  congenial  place  for  growth 
the  following  spring.  This  surprising  method  of  throwing  its  seeds  is  the 
origin  of  the  popular  name  touch-me-not,  and  the  scientific  name  Im- 
patiens by  which  these  plants  are  known. 

The  jewelweed  has  other  names — celandine  and  silver-leaf,  and  ladies’ 
ear-drop.  It  is  an  annual  with  a slight  and  surface-spreading  growth  of 
roots,  seeming  scarcely  strong  enough  to  anchor  the  branching  stems,  did 
not  the  plants  have  the  habit  of  growing  in  a community,  each  helping  to 
support  its  neighbor.  The  stem  is  round,  hollow  and  much  swollen  at  the

joints;  it  is  translucent,  filled  with  moisture,  and  its  outer  covering  is  a 
smooth  silken  skin,  which  may  be  readily  stripped  off.  Both  species  of 
jewelweed  vary  in  the  color  of  their  stems,  some  being  green,  others  red 
and  some  dark  purple ; and  all  the  differing  colors  may  be  found  within  a 
few  yards  of  each  other. 

The  leaves  are  alternate,  dark  green  above  and  a lighter  shade  below, 
ovate  in  form  with  scalloped  edges,  with  midrib  and  veins  very  prominent 
beneath  and  depressed  on  the  upper  side ; they  are  smooth  on  both  sides 
to  the  unaided  eye,  but  with  a lens  a film  of  fine,  short  hairs  may  be  seen, 
particularly  on  the  under  side.  When  plunged  beneath  clear  water,  they 
immediately  take  on  the  appearance  of  burnished  silver;  when  removed, 
no  drop  remains  on  their  surface. 

The  flower  stems  spring  from  the  axils  of  the  leaves  and  are  very 
slender  and  thread-like,  and  the  flowers  nod  and  swing  with  every  breeze. 
They  grow  in  open,  drooping  clusters,  few  blossoms  open  at  a time,  and 
with  buds  and  seed-capsules  present  in  various  stages  of  growth. 

The  jewelweed  is  involuntarily  most  hospitable,  and  always  houses 
many  uninvited  guests,  as  well  as  the  bee-callers  which  are  invited.  Galls 
are  formed  on  the  leaves  and  flowers ; the  hollow  stems  are  inhabited  by 
stalk-borers ; leaf-miners  live  between  the  upper  and  under  surfaces  of  the 
leaves,  making  curious  arabesque  patterns  and  initials  as  if  embroidering 
milady’s  green  gown. 

LESSON  CXLV 

The  Jewelweed,  or  Touch-me-not 

Leading  thought — The  jewelweed  may  be  found  by  the  brookside,  in 
swamps,  or  in  any  damp  and  well-shaded  area.  It  is  provided  with  a 
remarkable  contrivance  for  scattering  its  seeds  far  afield.  It  has  no 
liking  for  open  sunny  places,  unless  very  damp.  There  are  two  kinds, 
often  found  growing  together,  though  the  spotted  touch-me-not  (7m- 
patiens  biflora)  is  said  to  be  more  widely  distributed  than  its  relative — the 
golden,  or  pale,  touch-me-not  ( Impatiens  aurea). 

Method — The  jewelweeds  should  be  studied  where  they  are  growing; 
but  if  this  is  impracticable,  a large  bouquet  of  both  kinds  (if  possible), 
bearing  buds,  blossoms,  and  seed-capsules,  and  one  or  two  plants  with 
roots,  may  be  brought  to  the  schoolroom. 

In  the  fields  the  children  may  see  how  well  the  plant  is  provided 
with  means  to  sustain  itself  in  its  chosen  ground,  and  thus  lead  them 
to  look  with  keener  eyes  at  other  common  weeds. 

Observations — 1 . Do  you  think  the  jewelweed  is  an  annual,  sustaining 
life  in  its  seeds  during  winter,  or  do  its  roots  survive  ? 

2.  Do  the  roots  strike  deeply  into  the  soil,  or  spread  near  the  surface  ? 

3.  Study  the  stem;  is  it  hard  and  woody  or  juicy  and  translucent, 
rough  or  smooth,  solid  or  hollow? 

4.  Note  the  shape  and  position  of  the  leaves;  do  they  grow  opposite 
or  alternately  on  the  stalk?  Are  their  edges  entire,  toothed  or  scalloped? 
Do  they  vary  in  color  on  upper  and  lower  surface?  Are  they  smooth  or 
in  the  least  degree  rough  or  hairy?  Plunge  a plant  under  clear  water  in  a 
good  light  and  observe  the  beautiful  transformation.  Does  the  water 
cling  to  the  leaves?

5.  Where  do  the  flower-stems  spring  from  the  main  stalk?  Do  the 
flowers  grow  singly  or  in  clusters  ? Do  the  blossoms  all  open  at  nearly  the 
same  time  or  form  a succession  of  bud,  flower  and  seed  on  the  same  stem? 

6.  Study  the  parts  of  the  flower.  Find  the  four  sepals  and  describe 
the  shape  and  position  of  each.  Describe  the  nectar-sac  in  the  nectar- 
horn.  Can  you  find  the  two  petals?  Can  you  see  that  each  petal  has  a 
lobe  near  where  it  joins  the  stem?  Find  the  little  knob  hanging  down 
above  the  entrance  of  the  nectar-sac;  of  what  is  it  composed?  Look  at  it 
with  a lens,  and  tell  how  many  stamens  unite  to  make  the  knob  ? Where 
is  the  pollen  and  what  is  its  color?  What  insect  do  you  think  could 
reach  the  nectar  at  the  bottom  of  the  spurred  sac?  Could  any  insect  get 
at  the  nectar  without  rubbing  its  back  against  the  flat  surface  of  the 
pollen  boxes?  What  remains  after  the  stamens  fall  off?  Describe  how 
the  bees  do  the  work  of  pollenation  of  the  jewelweeds.  Write  or  tell  as  a 
story  your  own  observations  on  the  actions  of  the  different  bees  visiting 
these  flowers. 

7.  Carefully  observe  a seed-capsule  without  touching  it;  can  you  see 
the  lines  of  separation  between  its  sections?  How  many  are  there? 
What  happens  when  the  pod  is  touched?  Are  the  loosened  sections 
attached  at  the  stem,  or  at  the  apex  of  the  pod?  Hold  a pod  at  arm’s 
length  when  discharging  its  contents  and  measure  the  distance  to  which 
the  seeds  are  thrown.  Of  what  use  is  this  habit  of  seed-throwing  to  the 
plant? 

8.  Describe  the  differences  in  shape  and  color  between  the  pale  yellow 
and  the  orange  jewelweeds.  Watch  to  see  if  the  same  insects  visit  both. 
Which  species  do  you  think  is  best  suited  to  the  bumblebees  ? 


MULLEIN 
Teacher's  Story 


“ I like  the  plants  that  you  call  weeds, — 

Sedge,  hardback,  mullein,  yarrow,— 

Which  knit  their  leaves  and  sift  their  seeds 
Where  any  grassy  wheel-track  leads 
Through  country  by-ways  narrow 

— Lucy  Larcom. 

We  take  much  pride  unto  ourselves  because  we  belong  to  the  chosen 
few  of  the  “fittest,”  which  have  survived  in  the  struggle  for  existence. 
But,  if  we  look  around  upon  other  members  of  this  select  band,  we 
shall  find  many  lowly  beings  which  we  do  not  ordinarily  recognize  as  our 
peers.  Mullein  is  one  of  them,  and  after  we  study  its  many  ways  of 
“winning  out”  then  may  we  bow  to  it  and  call  it  “brother.” 

I was  wandering  one  day  m a sheep  pasture  and  looking  curiously  at 
the  few  plants  left  uneaten.  There  was  a great  thistle  with  its  sharp 
spines  and  the  pearly  everlasting — too  woolly  and  anaemic  to  be  appetiz- 
ing even  to  a sheep ; and  besides  these,  there  was  an  army  of  mullein 
stalks — tall,  slim,  and  stiff-necked,  or  branching  like  great  candelabra, 
their  upper  leaves  adhering  alternately  to  the  stalks  for  half  their 
length.  I stopped  before  one  of  them  and  mentally  asked,  “Why  do 


Wild-Flower  Study 


583 


the  sheep  not  relish  you  ? 
Are  you  bitter?”  I took  a 
bite,  Nebuchadnezzar-like, 
and  to  my  untrained  taste  it 
seemed  as  good  fodder  as  any; 
but  my  tongue  smarted  and 
burned  for  some  time  after, 
from  being  pricked  by  the  felt 
which  covered  the  leaf.  I 
recalled  the  practical  joke  of 
which  my  grandmother  once 
made  me  the  victim ; she  told 
me  that  to  be  beautiful,  I 
needed  only  to  rub  my  cheeks 
with  mullein  leaves,  an  ex- 
perience which  convinced  me 
that  there  were  other  things 
far  more  desirable  than  beauty 
— comfort,  for  instance.  This 
felt  on  the  mullein  is  beautiful, 
when  looked  at  through  a 
microscope;  it  consists  of  a 
fretwork  of  little,  white,  sharp 
spikes.  No  wonder  my  cheeks 
were  red  one  day  and  purple 
the  next,  and  no  wonder  the 
sheep  will  not  1 eat  it  unless 
starved!  This  frostlike  felt 
covering  not  only  keeps  the 
mullein  safe  from  grazing  ani- 
mals but  it  also  keeps  the 
water  from  evaporating  from 
the  leaf  and  this  enables  the 
plant  to  withstand  drought. 
I soon  discovered  another 
means  devised  by  the  mullein 
for  this  same  purpose,  when  I 
tried  to  dig  up  the  plant  with 
a stick;  I followed  its  tap- 
root down  far  enough  to 
understand  that  it  was  a sub- 
soiler  and  reached  below  most 
other  plants  for  moisture  and 
food.  Although  it  was  late 
autumn,  the  mullein  was  still 
in  blossom ; there  were  flowers 
near  the  tip  and  also  one  here  and  there  on  the  seed-crowded  stem.  I 
estimated  there  were  hundreds  of  seed-capsules  on  that  one  plant;  I 
opened  one,  still  covered  with  the  calyx-lobes,  and  found  that  the 
mullein  was  still  battling  for  survival;  for  I found  this  capsule  and 
many  others  inhabited  by  little  brown-headed  white  grubs,  which  gave 
an  exhibition  of  St.  Vitus  dance  as  I laid  open  their  home.  They  were  the 


Mullein.

young  of  a snout  beetle,  which  is  a far  more  dangerous  enemy  of  the 
mullein  than  is  the  sheep. 

The  mullein  plant  is  like  the  old  woman  who  lived  in  a shoe  in  the 
matter  of  blossom-children ; she  has  so  many  that  they  are  unkempt  and 

irregular,  but  there  are  normally  four 
yellow  or  white  petals  and  a five-lobed 
calyx.  I have  never  been  able  to  solve 
the  problem  of  the  five  stamens  which, 
when  the  flower  opens,  are  folded 
together  in  a knock-kneed  fashion.  The 
upper  three  are  bearded  below  the 
anthers,  the  middle  being  the  shortest. 
The  lower  two  are  much  longer  and  have 
no  fuzz  on  their  filaments;  they  at  first 
' stand  straight  out,  with  the  stigma 
between  them ; but  after  the  upper 
^ anthers  have  shed  their  pollen,  these 
j,  2.  Mullein  flowers  in  different  stages,  stamens  curve  up  like  boars  teeth  and 
j.  Mullein  seed  enlarged.  4.  A bit  splash  their  pollen  on  the  upper  petals, 
of  Mullein  leaf  enlarged.  the  stigma  protruding  desolately  and 
one-sidedly  below.  Later  the  corolla, 
stamens  and  all,  falls  off,  leaving  the  stigma  and  style  attached  to  the 
seed-capsule. 

The  color  of  the  mullein  flowers  varies  from  lemon-yellow  to  white. 
The  filaments  are  pale  yellow;  the  anthers  and  pollen,  orange.  The  seed- 
capsule  is  encased  in  the  long  calyx-lobes,  and  is  shaped  like  a blunt  egg. 
Cutting  it  in  two  crosswise,  the  central  core,  tough  and  flattened  and 
almost  filling  the  capsule,  is  revealed  and,  growing  upon  its  surface,  are 
numberless  tiny,  brown  seeds,  as  fine  as  gunpowder.  Later  the  capsule 
divides  partially  in  quarters,  opening  wide  enough  to  shake  out  the  tiny 
seeds  with  every  wandering  blast.  The  seed,  when  seen  through  a lens, 
is  very  pretty;  it  looks  like  a section  of  a corncob,  pitted  and  ribbed.  A 
nice  point  of  investigation  for  some  junior  naturalist  is  to  work  out  the 
fertilization  of  the  mullein  flower,  and  note  what  insects  assist.  The 
mullein  has  another  spoke  in  the  wheel  of  its  success.  The  seed,  scattered 
from  the  sere  and  dried  plants,  settles  comfortably  in  any  place  where  it 
can  reach  the  soil,  and  during  the  first  season  grows  a beautiful  velvety 
rosette  of  frosted  leaves.  No  wonder  Europeans  grow  it  in  gardens  under 
the  name  of  the  “American  velvet  plant.”  These  rosettes  lie  flat  under 
the  snow,  with  their  tap-roots  strong  and  already  deep  in  the  soil,  and  are 
ready  to  begin  their  work  of  food-making  as  soon  as  the  spring  sun  gives 
them  power. 

LESSON  CXLVI 
Mullein 

Leading  thought — The  mullein  has  its  leaves  covered  with  felt,  which 
prevents  evaporation  during  the  dry  weather  and  also  prevents  animals 
from  grazing  upon  the  plant.  It  has  a deep  root,  and  this  gives  moisture 
and  food  beyond  the  reach  of  most  other  plants.  It  blossoms  all  summer 
and  until  the  snow  comes  in  the  autumn,  and  thus  forms  many,  many 
seeds,  which  the  wind  plants  for  it;  and  here  in  our  midst  it  lives  and 
thrives  despite  us. 


Wild-Flower  Study 


5*5 


Method — The  pupils  should  have  a field  trip  to  see  what  plants  are  left 
uneaten  in  pastures,  and  thus  learn  where  mullein  grows  best.  The 
flower  or  seed  stalk,  with  basal  leaves  and  root,  may  be  brought  to  the 
schoolroom  for  the  lesson. 

Observations — 1.  Where  does  the  mullein  grow?  Do  you  ever  see  it 
in  swamps  or  woodlands?  Do  cattle  or  sheep  eat  it?  Why?  Does  it 
flourish  during  the  summer  drought?  How  is  it  clothed  to  prevent  the 
evaporation  of  its  sap?  Look  at  a mullein  leaf  with  a lens  and  describe 
its  appearance. 

2.  What  sort  of  a root  has  the  mullein?  How  is  its  root  adapted  to 
get  moisture  and  plant  food  which  other  plants  cannot  reach  ? Describe 
the  flowering  stalk.  How  are  the  leaves  arranged  on  it  and  attached  to 
it?  Are  there  several  branching  flower  stalks  or  a single  one? 

3.  Describe  the  flower  bud.  Do  the  mullein  flowers  nearest  the  base 
or  the  tip  begin  to  blossom  first?  Is  this  invariable,  or  do  flowers  open 
here  and  there  irregularly  on  the  stem  during  the  season  ? 

4.  Describe  the  mullein  flower.  How  many  lobes  has  the  calyx? 
Are  these  covered  with  felt?  How  many  petals?  Are  there  always  this 
number?  Are  the  petals  of  the  same  size?  Are  they  always  regular  in 
shape  ? 

5.  How  many  stamens?  How  do  the  upper  three  differ  from  the 
lower  two?  Describe  the  style  and  stigma.  What  are  the  colors  of 
petals,  anthers  and  stigma?  What  insects  do  you  find  visiting  the  flow- 
ers? 

6.  Describe  the  seed-capsule,  its  shape  and  covering.  Cut  it  across 
and  describe  the  inside.  Where  are  the  seeds  borne?  Are  there  many? 
Look  at  the  seed  with  a lens,  and  describe  it.  How  does  the  capsule  open 
and  by  what  means  are  the  seeds  scattered? 

7.  Does  the  mullein  grow  from  the  seed  to  maturity  in  one  year? 
How  does  it  look  at  the  end  of  the  first  season?  Describe  the  winter 
rosette,  telling  how  it  is  fitted  to  live  beneath  the  snows  of  winter.  What 
is  the  advantage  of  this  habit? 

8.  Write  a theme  telling  all  the  ways  the  mullein  has  of  flourishing 
and  of  combating  other  plants. 


“ The  mullein's  pillar , tipped  with  golden  flowers, 

Slim  rises  upward,  and  yon  yellow  bird 
Shoots  to  its  top."

“ Sober  dress  never  yet  made  you  sullen, 

Style  or  size  never  brought  you  a blush; 

You're  the  envy  of  weavers,  O,  Mullein, 

For  no  shuttle  can  mimic  your  plush. 

With  your  feet  in  the  sand  you  were  born, 

Woolly  monk  of  the  thorn-field  and  fallow, 

But  your  heart  holds  the  milk  of  the  mallow, 

And  your  head  wears  the  bloom  of  the  corn."

THE  TEASEL 
Teacher's  Story 

The  old  teasel  stalks  standing  gaunt  and  gray  in  the  fields,  braving  the 
blasts  of  winter,  seem  like  old  suits  of  armor,  which  elicit  admiration  from 
us  for  the  strength  and  beauty  of  the  protecting  visor,  breast-plate  and 
gauntlets,  and  at  the  same  time  veer  our  thoughts  to  the  knights  of  old 

who  once  wore  them 
in  the  fray.  Thus, 
with  the  teasel,  we 
admire  this  panoply 
ot  spears,  and  they 
recall  the  purple  flow- 
ers and  the  ribbed 
seeds  which  were  once 
the  treasure  of  every 
spear-guarded  cavity 
and  the  proud  reason 
of  every  lance  at  rest. 

Let  us  study  this 
plant  in  armor : First, 
its  stem  is  tough, 
woody,  hollow,  with 
ridges  extending  its 
full  length  and  each 
ridge  armed  with 
spines  which  are  quite 
wide  at  the  base  and 
very  sharp.  It  is  im- 
possible to  take  hold 
anywhere  without  be- 
ing pricked  by  either 
large  or  small  spines. 
The  leaves  are  just 
fitted  for  such  a stem. 
They  are  long,  lanceo- 
late, set  opposite  in 
pairs,  rather  coarse  in  texture,  with  a stiff,  whitish  midrib ; the  bases  of 
the  two  leaves  closely  clasp  the  stem;  the  midrib  is  armed  below  with  a 
row  of  long,  white,  recurved  prickers,  and  woe  unto  the  tongue  of  grazing 
beast  that  tries  to  lift  this  leaf  into  the  mouth.  If  one  pair  of  clasping 
leaves  point  east  and  west,  the  next  pairs  above  and  below  point  north 
and  south. 

The  flower  stems  come  off  at  the  axils  of  the  leaves  and  therefore  each 
pair  stands  at  right  angles  to  the  ones  above  and  below.  But  if  the 
teasel  protects  its  stem  and  leaves  with  spikes,  it  does  more  for  its  flowers, 
which  are  set  in  dense  heads  armed  with  spines,  and  the  head  is  set  in  an 
involucre  of  long,  upcurving  spiny  prongs.  If  we  look  at  it  carefully,  the 
teasel  flower-head  wins  our  admiration,  because  of  the  exquisite  geomet- 
rical design  made  by  the  folded  bases  of  the  spines,  set  in  diagonal  rows. 
If  we  pull  out  a spine,  we  find  that  it  enlarges  toward  the  base  to  a tri- 
angular piece  that  is  folded  at  right  angles  for  holding  the  flower.  Note 


The  teasel. 


Wild -Flower  Study

that  the  spiny  bracts  at  the  tip  of  the  flower-head  are  longer  and  more 
awesome  than  those  at  the  sides;  if  we  pass  our  hands  down  over  the 
flower-head  we  feel  how  stiff  the  spines,  or  bracts  are,  and  can  hear  them 
crackle  as  they  spring  back. 

The  teasel  has  a qui  e original  method  of  blossoming.  The  goldenrod 
begins  to  blossom  at  the  tip  of  the  flowering  branches  and  the  blossom-tide 
runs  inward  and  downward  toward  the  base.  The  clover  begins  at  the 
base  and  blossoms  toward  the  tip,  or  the  center.  But  the  teasel  begins  at 
the  middle  and  blossoms  both  ways,  and  how  it  knows  just  where  to  begin 
is  more  than  we  can  tell.  But  some  summer  morning  we  will  find  its 
flower-head  girt  about  its  middle  with  a wide  band  of  purple  blossoms; 
after  a few  days,  these  fade  and  drop  off,  and  then  there  a e two  bands, 
sometimes  four  rows  of  flowers  in  each,  and  sometimes  only  two.  Below 
the  lower  band  and  above  the  upper  band,  the  enfolding  bracts  are  filled 
with  little,  round-headed  lilac  buds,  while  between  the  two  rows  of  blos- 
soms the  protecting  bracts  hold  the  precious  growing  seed.  Away  from 
each  other  this  double  procession  moves,  until  the  lower  band  reaches  the 
pronged  involucre  and  the  upper  one  forms  a solid  patch  on  the  apex  of  the 
flower-head.  Since  the  secondary  blossom-heads  starting  from  the  leaf 
axils  are  younger,  we  may  find  all  stages  of  this  blossoming  in  the  flower- 
heads  of  one  plant. 

No  small  flower  pays  better  for  close  examination  than  does  that  of  the 
teasel.  If  we  do  not  pull  the  flower-head  apart,  what  we  see  is  a little 
purple  flower  consisting  of  a white  tube  with  four  purple  lobes  at  the  end, 
the  lower  lobe  being  a little  longer  than  the  others  and  turning  up  slightly 
at  its  tip;  projecting  from  between 
each  of  the  lobes,  and  fastened  to  the 
tube,  are  four  stamens  with  long, 
white  filaments  and  beautiful  purple 
anthers  filled  with  large,  pearly  white 
pollen  grains;  at  the  very  heart  of 
the  flower,  the  white  stigma  may  be 
seen  far  down  the  tube.  But  a little 
later,  after  the  anthers  have  fallen 
or  shriveled,  the  white  stigma  extends 
out  of  the  blossom  like  a long,  white 
tongue  and  is  crowded  with  white 
pollen  grains. 

But  to  see  the  flower  completely 
we  need  to  break  or  cut  a flower-head 
in  two.  Then  we  see  that  the  long 
white  tube  is  tipped  at  one  end  with 
purple  lobes  and  a fringe  of  anthers, 
and  at  the  other  is  set  upon  a little 
green,  fluffy  cushion  which  caps  the 
ovary;  the  shape  of  the  ovary  in  the 
flower  tells  us  by  its  form  how  the 
seed  will  look  later.  Enfolding  ovary 
and  tube  is  the  bract  with  its  spiny 
edges,  pushing  its  protecting  spear  Teasel  flower  and  seed  enlarged.  The  stigma 

outward,  but  not  so  far  out  as  the  \he  pollet  adhering  t0  itf  JBelow,  are 
opening  of  the  flower,  for  that  might  ■pollen  grains  greatly  magnified.

keep  away  the  insects  which  carry  the  teasel’s  pollen.  The  pollen  of 
the  teasel  is  white  and  globular,  with  three  little  rosettes  arranged  at  equal 
distances  upon  it  like  a bomb  with  three  fuses.  These  little  rosettes  are 
the  growing  points  of  the  pollen  grains  and  from  any  of  them  may 
emerge  the  pollen  tube  to  push  down  into  the  stigma.  The  teasel  pollen 
is  an  excellent  subject  for  the  children  to  study,  since  it  is  so  very  large; 
and  if  examined  with  a microscope  with  a three-fourths  objective,  the 
tubes  running  from  the  pollen  grains  into  the  stigma  may  be  easily  seen. 

In  blossoming,  the  teasel  does  not  always  seem  to  count  straight  in  the 
matter  of  rows  of  flowers.  There  may  be  more  rows  in  the  upper  band 
than  in  the  lower,  or  vice  versa;  this  is  especially  true  of  the  smaller 
secondary  blossoms.  But  though  the  teasel  flowers  fade  and  the 
leaves  fall  off,  still  the  spiny  skeleton  stands,  the  thorny  stalks  holding 
up  the  empty  flower-heads  like  candelabra,  from  which  the  seeds  are 
tossed  far  and  wide,  shaken  out  by  the  winds  of  autumn.  But  though 
battered  by  wintry  blasts,  the  teasel  staunchly  stands;  even  until  the 
ensuing  summer,  each  bract  on  guard  and  its  heart  empty  where  once 
was  cherished  blossom  and  seed.  Alas,  because  of  this  emptiness,  it  has 
been  debased  by  practical  New  England  housewives  into  a utensil  for 
sprinkling  clothes  for  ironing. 

The  spines  of  one  species  of  teasel  were,  in  earlier  times,  used  for  raising 
the  nap  on  woolen  cloth,  and  the  plant  was  grown  extensively  for  that 
purpose.  The  bees  are  fond  of  the  teasel  blossoms  and  teasel  honey  has 
an  especially  fine  flavor. 

The  teasels  are  biennial,  and  during  the  first  season,  develop  a rosette 
of  crinkled  leaves  which  have  upon  them  short  spines. 

LESSON  CXLVII 
The  Teasel 

Leading  thought — The  teasel  is  a plant  in  armor,  so  protected  that  it  can 
flourish  and  raise  its  seeds  in  pastures  where  cattle  graze.  It  has  a 
peculiar  method  of  beginning  to  blossom  in  the  middle  of  the  flower-head 

and  then  blossoming 
upward  and  down- 
ward from  this  point. 

Method — In  Sep- 
tember, bring  in  a 
teasel  plant  which 
shows  all  stages  of 
blossoming,  and  let 
the  pupils  make  ob- 
servations in  the 
schoolroom. 

Observations — i. 
Where  does  the  tea- 
sel grow?  Is  it  ever 
eaten  by  cattle? 
Why  not?  How  is  it 
protected? 

2.  What  sort  of 
stem  has  it?  Is  it 


Wild-Flower  Study 


589 


hollow  or  solid?  Where  upon  it  are  the  spines  situated?  Are  the 
spines  all  of  the  same  size  ? Can  you  take  hold  of  the  stem  anywhere 
without  being  pricked  ? 

3.  What  is  the  shape  of  the  leaves?  How  do  they  join  the  stem? 
Are  the  leaves  set  opposite  or  alternate?  If  one  pair  points  east  and 
west  in  which  direction  will  the  pairs  above  and  below  point?  How 
and  where  are  the  leaves  armed?  How  does  the  cow  or  sheep  draw 
the  leaves  into  the  mouth  with  the  tongue?  If  either  should  try  to  do 
this  with  the  teasel,  how  would  the  tongue  be  injured? 

4.  Where  do  the  flower  stems  come  off?  Do  they  come  off  in  pairs? 
How  are  the  pairs  set  in  relation  to  each  other? 

5.  What  is  the  general  appearance  of  the  teasel  flower-head?  De- 
scribe the  long  involucre  prongs  at  the  base.  If  the  teasel  is  in  blossom, 
where  do  you  find  the  flowers?  How  many  girdles  of  flowers  are  there 
around  the  flower-head?  How  many  rows  in  one  girdle?  Where  did  the 
first  flowers  blossom  in  the  teasel  flower-head?  Where  on  the  head  will 
the  last  blossoms  appear?  Where  are  the  buds  just  ready  to  open? 
Where  are  the  ripened  seeds? 

6.  Examine  a single  flower.  How  is  it  protected?  Cut  out  a flower 
and  bract  and  see  how  the  long-spined  bract  enfolds  it.  Is  the  bract  spear 
long  enough  to  keep  the  cattle  from  grazing  on  the  blossom?  Is  it  long 
enough  to  keep  the  bees  and  other  insects  from  visiting  the  flowers? 
Where  are  the  longest  spines  on  the  teasel  head? 

7.  Study  a single  flower.  What  is  the  shape  of  its  corolla?  How  is 
it  colored?  What  color  are  the  stamens?  How  many?  Describe  the 
pollen.  If  the  pollen  is  being  shed  where  is  the  stigma  ? After  the  pollen 
is  shed,  what  happens  to  the  stigma? 

8.  What  do  you  find  at  the  base  of  the  flower?  How  does  the  young 
seed  look?  Later  in  the  season  take  a teasel  head  and  describe  how  it 
scatters  its  seed.  How  do  the  ripe  seeds  look?  How  long  will  the  old 
teasel  plants  stand? 

9.  For  what  were  teasels  once  used?  How  many  years  does  a teasel 
plant  live?  How  does  it  look  at  the  end  of  its  first  season?  How  is  this 
an  advantage  as  a method  of  passing  the  winter? 


QUEEN  ANNE’S  LACE,  OR  WILD  CARROT 
Teacher's  Story 

Queen  Anne  was  apparently  given  to  wearing  lace  made  in  medallion 
patterns ; and  even  though  we  grant  that  her  lace  is  most  exquisite  in 
design  as  well  as  in  execution,  we  wish  most  sincerely  that  there  had 
been  established  in  America  such  a high  tariff  on  this  royal  fabric  as  to 
have  prohibited  its  importation.  It  has  for  decades  held  us  and  our 
lands  prisoners  in  its  delicate  meshes,  it  being  one  of  the  most  stubborn 
and  persistent  weeds  that  ever  came  to  us  from  over  the  seas. 

But  for  those  people  who  admire  lace  of  intricate  pattern,  and 
beautiful  blossoms  whether  they  grow  on  scalawag  plants  or  not,  this 
medallion  flower  attributed  to  Queen  Anne  is  well  worth  studying.  It 
belongs  to  the  family  Umbelliferae,  which  one  of  my  small  pupils  always 


Handbook  of  N ature-Study 


called  umbrelliferae  because, 
he  averred,  they  have  um- 
brella blossoms.  In  the  case 
of  Queen  Anne’s  lace  the 
flower-cluster,  or  umbel,  is 
made  up  of  many  smaller 
umbels,  each  a most  perfect 
flower-cluster  in  itself.  Each 
tiny  white  floret  has  five 
petals  and  should  have  five 
stamens  with  creamy  anthers, 
but  often  has  only  two. 
However,  it  has  always  at  its 
center  two  fat  little  pistils  set 
snugly  together,  and  it  rests 
in  a solid,  bristly,  green,  cup- 
like calyx.  Twenty  or  thirty 
of  these  little  blossoms  are  set 
in  a rosette,  the  stems  of 
graded  length ; and  where  the 
bases  of  the  stems  meet  are 
some  long,  pointed,  narrow 
bracts,  which  protectingly 
brood  the  flowers  in  the  bud 
and  the  seeds  as  they  ripen. 
Each  of  these  little  flower- 
clusters,  or  umbels,  has  a long 
stem,  its  length  being  just  fit 
to  bring  it  to  its  right  place  in 
the  medallion  pattern  of  this 
royal  lace.  And  these  stems 
also  have  set  at  their  bases 
some  bracts  with  long,  thread- 
like lobes,  which  make  a deli- 
cate, green  background  for 
the  opening  blossoms;  these 
bracts  curl  up  protectingly 
about  the  buds  and  the  seeds. 
If  we  look  straight  into  the 
large  flower-cluster,  we  can 
see  that  each  component  clus- 
ter, or  umbelicel,  seems  to 
have  its  own  share  in  making 
the  larger  pattern;  the  out- 
side blossoms  of  the  outside 
Queen  Anne's  lace , or  wild  carrot  clusters  have  the  outside

beautiful  border  and  calling 
to  mind  the  beautiful  flowers  of  the  Composites.  At  the  very  center  of 
this  flower  medallion,  there  is  often  a larger  floret  with  delicate  wine- 
colored  petals ; this  striking  floret  is  not  a part  of  a smaller  flower-cluster, 
but  stands  in  stately  solitude  upon  its  own  isolated  stem.  The  reason 


Wild-Flower  Study 


591 


for  this  giant  floret  at  the  center  of  the  wide,  circular  flower-cluster 
is  a mystery;  and  so  far  as  I know,  the  botanists  have  not  yet  explained 
the  reason  for  its  presence.  May. we  not,  then,  be  at  liberty  to  explain  its 
origin  on  the  supposition  that  her  Royal  Highness,  Queen  Anne,  was  wont 
to  fasten  her  lace  medallions  upon  her  royal  person  with  garnet-headed 
pins? 

When  the  flowers  wither  and  the  seeds  begin  to  form,  the  flower-cluster 
then  becomes  very  secretive ; every  one  of  the  little  umbels  turns  toward 
the  center,  its  stem  curving  over  so  that  the  outside  umbels  reach  over  and 
“tuck  in”  the  whole  family;  and  the  threadlike  bracts  at  the  base  reach 
up  as  if  they,  too,  were  in  the  family  councils,  and  must  do  their  slender 
duty  in  helping  to  make  the  fading  flowers  into  a little,  tightfisted  clump  ; 
and  all  of  this  is  done  so  that  the  precious  seeds  may  be  safe  while  they  are 
ripening.  Such  little  porcupines  as  these  seeds  are ! Each  seed  is  clothed 
with  long  spines  set  in  bristling  rows,  and  is  a most  forbidding-looking 
youngster  when  examined  through  a lens ; and  yet  there  is  method  in  its 
spininess,  and  we  must  grudgingly  grant  that  it  is  not  only  beautiful  in  its 
ornamentation  but  is  also  well  fitted 
to  take  hold  with  a will  when  wandering 
winds  sift  it  down  to  the  soil. 

The  wild  carrot  is  known  in  some 
localities  as  the  “bird’s-nest  weed,”  be- 
cause the  maturing  seed-clusters,  .their 
edges  curving  inward,  look  like  little 
birds’  nests.  But  no  bird’s  nest  ever 
contained  so  many  eggs  as  does  this  imi- 
tation one.  In  one  we  counted  34  tiny 
umbels  on  which  ripened  782  seeds;  and 
the  plant,  from  which  this  “bird’s  nest” 
was  taken,  developed  nine  more  quite  as 
large. 

Altogether  the  wild  carrot  is  well 
fitted  to  maintain  itself  in  the  struggle 
for  existence,  and  is  most  successful  in  crowding  out  its  betters  in  pas- 
ture and  meadow.  Birds  do  not  like  its  spiny  seeds;  the  stem  of  the 
plant  is  tough  and  its  leaves  are  rough  and  have  an  unpleasant  odor  and 
acrid  taste,  which  render  it  unpalatable  to  grazing  animals.  Winter’s 
cold  cannot  harm  it,  for  it  is  a biennial;  its  seeds  often  germinate  in  the 
fall,  sending  down  long,  slender  taproots  crowned  with  tufts  of  incon- 
spicuous leaves ; it  thus  stores  up  a supply  of  starchy  food  which  enables 
it  to  start  early  the  next  season  with  great  vigor.  The  root,  when  the 
plant  is  fully  grown,  is  six  or  eight  inches  long,  as  thick  as  a finger  and 
yellowish  white  in  color ; it  is  very  acrid  and  somewhat  poisonous. 

The  surest  way  of  exterminating  the  Queen  *Anne’s  lace  is  to  prevent 
its  prolific  seed  production  by  cutting  or  uprooting  the  plants  as  soon  as 
the  first  blossoms  open. 


“ ’Tis  Eden  everywhere  to  hearts  that  listen 
And  watch  the  woods  and  meadows  grow. ”

LESSON  CXLVIII 

Queen  Anne’s  Lace,  or  Wild  Carrot 

Leading  thought — Queen  Anne’s  lace  is  a weed  which  came  to  us  from 
Europe  and  flourishes  better  here  than  on  its  native  soil.  It  has  beautiful 
blossoms  set  in  clusters,  and  it  matures  many  seeds  which  it  manages  to 
plant  successfully. 

Method — The  object  of  this  lesson  should  be  to  show  the  pupils  how 
this  weed  survives  the  winter  and  how  it  is  able  to  grow  where  it  is  not 
wanted,  maintaining  itself  successfully,  despite  man’s  enmity.  The  weed 
is  very  common  along  most  country  roadsides,  and  in  many  pastures  and 
meadows.  It  blossoms  very  late  in  the  autumn,  and  is  available  for  les- 
sons often  as  late  as  November.  Its  seed-clusters  may  be  used  for  a lesson 
at  almost  any  time  during  the  winter. 

Observations — i.  Look  at  a wild  carrot  plant;  how  are  its  blossoms 
arranged?  Take  a flower-cluster,  what  is  its  shape?  How  many  small 
flower-clusters  make  the  large  one?  How  are  these  arranged  to  make  the 
large  cluster  symmetrical  ? 

2.  Take  one  of  the  little  flower-clusters  from  near  the  center,  and  one 
from  the  outside,  of  the  large  cluster ; how  many  little  flowers,  or  florets 
make  up  the  smaller  cluster?  Look  at  one  of  the  florets  through  a lens; 


Wild-Flower  Study 


593 


can  you  see  the  cup-shaped  calyx?  How  many  petals  has  it?  Can  you 
see  its  five  anthers  and  its  two  white  pistils? 

3.  Take  one  of  the  outer  florets  of  the  outside  cluster;  are  all  its 
flowers  the  same  shape?  How  do  they  differ?  Where  are  the  florets 
with  the  large  petals  placed  in  the  big  flower-cluster?  How  does  this  help 
to  make  “the  pattern?” 

4.  Do  the  outside  or  the  central  flowers  of  the  large  clusters  open 
first  ? Can  you  find  a cluster  with  an  almost  black  or  very  dark  red  floret 
at  its  center?  Is  this  dark  flower  a part  of  one  of  the  little  clusters  or  does 
it  stand  alone,  its  stem  reaching  directly  to  the  main  stalk?  Do  you 
think  it  makes  the  flowers  of  the  Queen  Anne’s  lace  prettier  to  have  this 
dark  red  floret  at  the  center? 

5.  Take  a flower-cluster  with  the  flowers  not  yet  open.  Can  you  see 
the  threadlike  green  bracts  that  close  up  around  each  bud  ? Can  you  see 
finely  divided,  threadlike  bracts  that  stand  out  around  the  whole  cluster? 
What  position  do  these  bracts  assume  when  the  flowers  are  open  ? What 
do  they  do  after  the  flowers  fade  and  the  seeds  are  being  matured? 

6.  What  is  the  general  shape  of  the  seed-cluster  of  the  wild  carrot? 
Have  you  ever  found  such  a cluster  broken  off  and  blowing  across  the 
snow  ? Do  you  think  this  is  one  way  the  seed  is  planted  ? 

7.  Examine  a single  seed  of  the  wild  carrot  with  a lens.  Is  it  round 
or  oblong?  Thin  or  flat?  Is  it  ridged  or  grooved?  Has  it  any  hooks  or 
spines  by  which  it  might  cling  to  the  clothing  of  passers-by,  or  to  the  hair 
or  fleece  of  animals,  and  thus  be  scattered  more  widely?  Does  the  seed 
cling  to  its  stem  or  break  away  readily  when  it  is  touched? 

8.  Take  one  seed-cluster  and  count  the  number  of  seeds  within  it. 
How  many  seed-clusters  do  you  find  on  a single  plant?  How  many 
seeds  do  you,  therefore,  think  a single  plant  produces? 

9.  What  should  you  consider  the  best  means  of  destroying  this  pro- 
lific weed? 

10.  What  do  you  think  is  the  reason  that  the  wild  carrot  remains 
untouched,  so  that  it  grows  vigorously  and  matures  its  seeds  in  lanes  and 
pastures  where  cattle  graze? 

1 1 . Have  you  noticed  any  birds  feeding  on  the  seeds  of  the  wild  carrot  ? 


I do  not  want  change:  I want  the  same  old  and  loved  things,  the  same  wild  flowers , 

the  same  trees  and  soft  ash-green;  the  turtle-doves,  the  blackbirds,  the  coloured  yellow- 
hammer  sing,  sing,  singing  so  long  as  there  is  light  to  cast  a shadow  on  the  dial , 
for  such  is  the  measure  of  his  song,  and  I want  them  in  the  same  place.  Let  me  find 
them  morning  after  morning,  the  starry-white  petals  radiating,  striving  upwards  to  their 
ideal.  Let  me  see  the  idle  shadows  resting  on  the  white  dust;  let  me  hear  the  humble-bees,  and 
stay  to  look  down  on  the  rich  dandelion  disc.  Let  me  see  the  very  thistles  opening  their  great 
crowns — I should  miss  the  thistles;  the  reed-grasses  hiding  the  moor-hen;  the  bryony  bine,  at 
first  crudely  ambitious  and  lifted  by  force  of  youthful  sap  straight  above  the  hedgerow  to  sink 
of  its  own  weight  presently  and  progress  with  crafty  tendrils;  swifts  shot  through  the  air  with 
outstretched  wings  like  crescent-headed  shaftless  arrows  darted  from  the  clouds;  the  chaffinch 
with  a feather  in  her  bill;  all  the  living  staircase  of  the  spring,  step  by  step,  upwards  to  the 
great  gallery  of  the  summer — let  me  watch  the  same  succession  year  by  year.

WEEDS 

" The  worst  weed  in  corn  may  be — corn.” 

— Professor  I.  P.  Roberts. 

Nature  is  the  great  farmer.  Continually 
she  sows  and  reaps,  making  all  the  forces  of 
the  universe  her  tools  and  helpers;  the  sun’s 
rays,  wind,  rain  and  snow,  insects  and  birds, 
animals  small  and  great,  even  to  the  humble 
burrowing  worms  of  the  earth — all  work 
mightily  for  her,  and  a harvest  of  some  kind 
is  absolutely  sure.  But  if  man  interferes  and 
insists  that  the  crops  shall  be  only  such  as  may 
benefit  and  enrich  himself,  she  seems  to  yield  a 
willing  obedience,  and  under  his  control  does 
immensely  better  work  than  when  unguided. 

“eye-servant.”  Let  the  master  relax  his  vigilance  for  ever  so  short  a 
time,  and  among  the  crops  of  his  desire  will  come  stealing  in  the  hardy, 
aggressive,  and  to  him,  useless  plants  that  seem  to  be  her  favorites. 

A weed  is  a plant  growing  where  we  wish  something  else  to  grow,  and 
a plant  may,  therefore,  be  a weed  in  some  locations  and  not  in  others. 
The  mullein  is  grown  in  greenhouses  in  England  as  the  American  velvet- 
plant.  Our  grandmothers  considered  “butter-and-eggs,”  a pretty  posy, 
and  planted  it  in  their  gardens,  wherefrom  it  escaped,  and  is  now  a bad 
weed  wherever  it  grows.  A weed  may  crowd  out  our  cultivated  plants, 
by  stealing  the  moisture  and  nourishment  in  the  soil  which  they  should 
have;  or  it  may  shade  them  out  by  putting  out  broad  leaves  and  shutting 
off  their  sunlight.  When  harvested  with  a crop,  weeds  may  be  unpala- 
table to  the  stock  which  feed  upon  it;  or  in  some  cases,  as  in  the  wild 
parsnip,  the  plant  may  be  poisonous. 

Each  weed  has  its  own  way  of  winning  in  the  struggle  with  our  crops, 
and  it  behooves  us  to  find  that  way  as  soon  as  possible  in  order  to  circum- 
vent it.  This  we  can  only  do  by  a careful  study  of  the  peculiarities  of  the 
species.  To  do  this  we  must  know  the  plant’s  life  history ; whether  it  is 
an  annual,  surviving  the  winter  only  in  its  seeds;  or  a biennial,  storing  in 
fleshy  root  or  in  broad,  green  leafy  rosette  the  food  drawn  from  the  soil 
and  air  during  tne  first  season,  to  perfect  its  fruitage  in  the  second  year; 
or  a perennial,  surviving  and  springing  up  to  spread  its  kind  and  pester  the 
farmer  year  after  year,  unless  he  can  destroy  it  “root  and  branch.” 
Purslane  is  an  example  of  the  first  class,  burdock  or  mullein  of  the 
second,  and  the  field  sorrel  or  Canada  thistle  of  the  third.  According

to  their  nature  the  farmer  must  use  different  means  of  extermination : he 
must  strive  to  hinder  the  annuals  and  biennials  from  forming  any  seed 
whatever;  and  where  perennials  have  made  themselves  a pest,  he  must 
put  in  a “hoed  crop,”  requiring  such  constant  and  thorough  tillage  that 
the  weed  roots  will  be  deprived  of  all  starchy  food  manufactured  by  green 
leaves  and  be  starved  out.  Especially  every  one  who  plants  a garden 
should  know  how  the  weeds  look  when  young,  for  seedlings  of  all  kinds 
are  delicate  and  easy  to  kill  before  their  roots  are  well  established. 

LESSON  CXLIX 
Outline  for  the  Study  of  a Weed 

1.  Why  do  we  call  a plant  a weed?  Is  a weed  a weed  wherever  it 
grows?  How  about  “butter  and  eggs”  when  it  grew  in  Grandmother’s 
garden?  Why  do  we  call  that  a weed  now?  What  did  Grandmother  call 
it? 

2 . In  how  many  ways  may  a weed  injure  our  cultivated  crops  ? 

3 . Why  must  we  study  the  habits  of  a weed  before  we  know  how  to 
fight  it? 

We  should  ask  of  every  weed  in  our  garden  or  on  our  land  the  following 
questions,  and  let  it  answer  them  through  our  observations  in  order  to 
know  why  the  weed  grows  where  it  chooses,  despite  our  efforts. 

4.  How  did  this  weed  plant  itself  where  I find  it  growing?  By  what 
agency  was  its  seed  brought  and  dropped? 

5.  What  kind  of  root  has  it?  If  it  has  a tap-root  like  the  mullein, 
what  advantage  does  it  derive  from  it?  If  it  has  a spreading  shallow- 
growing root  like  the  purslane  what  advantage  does  it  gain?  If  it  has  a 
creeping  rootstock  with  underground  buds  like  the  Canada  thistle,  how  is 
it  thereby  helped  ? 

6.  Is  the  stem  woody  or  fleshy?  Is  it  erect  or  reclining  or  climbing? 
Does  it  gain  any  advantage  through  the  character  of  its  stem? 

7.  Note  carefully  the  leaves.  Are  they  eaten  by  grazing  animals? 
If  not,  why?  Are  they  covered  with  prickles  like  the  teazel  or  fuzz  like 
the  mullein,  or  are  they  bitter  and  acrid  like  the  wild  carrot? 

8.  Study  the  blossoms.  How  early  does  the  weed  bloom?  How 
long  does  it  remain  in  bloom?  Do  insects  carry  pollen  for  the  flowers? 
If  so,  what  insects?  What  do  the  insects  get  in  return?  How  are  the 
flower  buds  and  the  ripening  seeds  protected  ?

THE  CROCUS 
Teacher's  Story 

The  crocus,  like  the  snowdrop,  cannot  wait  for  the 
snow  to  be  off  the  ground  before  it  pushes  up  its  gay 
blossoms,  and  it  has  thus  earned  the  gratitude  of  those 
who  are  winter  weary. 

The  crocus  has  a corm  instead  of  a bulb  like  the 
snowdrop  or  daffodil.  A corm  is  a solid,  thickened, 
underground  stem,  and  is  not  in  layers,  like  the  onion. 

The  roots  come  off  the  lower  side  of  the  corm.  The 
corm  of  the  crocus  is  well  wrapped  in  several,  usually 
five,  white  coats  with  papery  tips.  When  the  plant 
begins  to  grow  the  leaves  push  up  through  the  coats. 

The  leaves  are  grasslike  and  may  be  in  number  from  two  to  eight,  depend- 
ing on  the  variety.  Each  leaf  has  its  edge  folded,  and  the  white  midrib 
has  a plait  on  either  side,  giving  it  the  appearance  of  being  box-plaited  on 
the  under  side.  The  bases  of  the  leaves  enclosed  in  the  corm  coats  are 
yellow,  since  they  have  had  no  sunlight  to  start  their  starch  factories  and 
the  green  within  their  cells.  At  the  center  of  the  leaves  appear  the  blos- 
som buds,  each  enclosed  in  a sheath. 

The  petals  and  sepals  are  similar  in  color,  but  the  three  sepals  are  on 
the  outside,  and  their  texture,  especially  on  the  outer  side,  is  coarser  than 
that  of  the  three  protected  petals.  But  sepals  and  petals  unite  into  a 
long  tube  at  the  base.  At  the  very  base  of  this  corolla  tube,  away  down 
out  of  sight,  even  below  the  surface  of  the  ground,  is  the  seed-box,  or 
ovary.  From  the  tip  of  the  ovary  the  style  extends  up  through  the 
corolla-tube  and  is  tipped  with  a ruffled  three-lobed  stigma.

corms  of  the 
crocus. 


Cultivated-Plant  Study 


597 


The  three  stamens  are  set  at  the  throat 
of  the  corolla  tube.  The  anthers  are 
very  long  and  open  along  the  sides.  The 
anthers  mature  first,  and  shed  their  pol- 
len in  the  cup  of  the  blossom  where  any 
insect,  seeking  the  nectar  in  the  tube  of 
the  corolla,  must  become  dusted  with  it. 

However,  if  the  stigma  lobes  fail  to  get 
pollen  from  other  flowers,  they  later 
spread  apart  and  curl  over  until  they 
reach  some  of  the  pollen  of  their  own 
flower. 

Crocus  blossoms  have  varied  colors: 
white,  yellow,  orange,  purple,  the  latter 
often  striped  or  feather-veined.  And, 
while  many  seeds  like  tiny  pearls,  are 
developed  in  the  oblong  capsule,  yet 
it  is  chiefly  by  its  corms  that  the 
crocus  multiplies.  On  top  of  the  mother 
corm  of  this  year  develop  several  small 
corms,  each  capable  of  growing  a plant 
next  year.  But  after  two  years  of  this 
second-story  sort  of  multiplication  the 
young  crocuses  are  pushed  above  the  sur- 
face of  the  ground.  Thus,  they  need  to 
be  replanted  every  two  or  three  years. 

Crocuses  may  be  planted  from  the  first  of 
October  until  the  ground  freezes.  They 
make  pretty  borders  to  garden  beds  and 
paths.  Or  they  may  be  planted  in  lawns 
without  disturbing  the  grass,  by  punching  a hole  with  a stick  or  dibble  and 
dropping  in  a corm  and  then  pressing  back  the  soil  in  place  above  it.  The 
plants  will  mature  before  the  grass  needs  to  be  mowed.

LESSON  CL 
The  Crocus 

Leading  thought — The  crocuses  appear  so  early  in  the  spring,  because 
they  have  food  stored  in  underground  storehouses.  They  multiply  by 
seeds  and  by  corms. 

Method — If  it  is  possible  to  have  crocuses  in  boxes  in  the  school- 
room windows,  the  flowers  may  thus  best  be  studied.  Otherwise, 
when  crocuses  are  in  bloom  bring  them  into  the  schoolroom,  bulbs  and  all, 
and  place  them  where  the  children  may  study  them  at  leisure. 

Observations — i . At  what  date  in  the  spring  have  you  found  crocuses 
in  blossom?  Why  are  they  able  to  blossom  so  much  earlier  than  other 
flowers? 

2.  Take  a crocus  just  pushing  up  out  of  its  bulb.  How  many  over- 
coats protect  its  leaves  ? What  is  at  the  very  center  of  the  bulb?  Has 
the  flower  bud  a special  overcoat?

3.  Describe  the  leaves.  How  are  they  folded  in  their  overcoats? 
Whac  color  are  they  where  they  have  pushed  out  above  their  overcoats! 
What  color  are  they  within  the  overcoats  ? Why  ? 

4.  Do  the  flowers  or  the  leaves  have  stems,  or  do  they  arise  directly 
from  the  bulb  ? 

5.  What  is  the  shape  of  the  open  crocus  flower?  Can  yon  tcH  the 
difference  between  sepals  and  petals  in  color?  Can  you  tell  the  difference 
by  their  position?  Or  by  their  texture  above  or  below?  As  yon  2ook 
into  the  flower,  which  make  the  points  of  the  triangle,  the  sepals  or  tho 
petals  ? 

6.  Describe  the  anthers.  How  long  are  they?  How  many  are  there? 
How  do  they  open?  What  is  the  color  of  the  pollen?  Describe  how  a bee 
becomes  dusted  with  pollen  ? Why  does  the  bee  visit  the  crocus  lelossom? 
If  she  finds  nectar  there,  where  is  it? 

7 . Describe  the  stigma.  Open  a flower  and  see  how  long  tho  stylo  is? 
How  do  the  sepals  and  petals  unite  to  protect  the  style?  Where  is  the 
seed-box?  Is  it  so  far  down  that  it  is  below  ground?  How  many  seeds 
are  developed  from  a single  blossom? 

8.  How  many  colors  do  you  find  in  the  crocus  flowers?  Which  9£Q 
the  prettiest  in  the  lawn?  Which,  in  the  flower  beds? 

9.  How  do  the  crocus  blossoms  act  in  dark  and  stormy  weather? 
When  do  they  open?  How  does  this  benefit  them? 

10.  How  do  the  crocus  bulbs  multiply?  Why  do  they  lift  thcmscivcs 
out  of  the  ground  and  thus  need  resetting. 

11.  Describe  how  to  raise  crocuses  best;  the  kind  of  soil,  the  time  of 
planting,  and  the  best  situations..

THE  DAFFODILS  AND  THEIR  RELATIVES 
Teacher's  Story 

“ Daffydown  Billy  came  up  in  the  cold  from  the  hr  own  mold, 
Although  the  March  breezes  blew  keen  in  her  face, 

Although  the  white  snow  lay  on  many  a place." 


Thus,  it  is  that  Miss  Warner’s 
stanzas  tell  us  the  special  reason 
we  so  love  the  daffodils.  They 
bring  the  sunshine  color  to  the 
sodden  earth,  when  the  sun  is 
chary  of  his  favors  in  our  northern 
latitude;  and  the  sight  of  the 
daffodils  floods  the  spirit  with  a 
sense  of  sunlight. 

The  daffodils  and  their  rela- 
tives, the  jonquils  and  narcissus, 
are  interesting  when  we  stop  to 
read  their  story  in  their  form. 

The  six  segments  of  the  perianth, 
or,  as  we  would  say,  the  three 
bright-colored  sepals  and  the 
three  inner  petals  of  the  flower, 
are  different  in  shape;  but  they 
all  look  like  petals  and  stand  out 
in  star-shape  around  the  flaring 
end  of  the  flower  tube,  which, 
because  of  its  shape,  is  called  the 
corona,  or  crown;  however,  it 
looks  more  like  a stiff  little  petti- 
coat extending  out  in  the  middle 
of  the  flower  than  it  does  like  a 
crown.  The  crown  is  simply  the 
widened  end  of  the  tube  of  the 
flower,  as  maybe  seen  by  opening  Daffodil. 

a flower  lengthwise ; the  six  seem- 
ing petals  will  peel  off  the  tube,  showing  that  they  are  fastened  to  the 
outside  of  it.  When  we  look  down  into  the  crown  of  one  of  these 
flowers,  we  see  the  long  style  with  its  three-lobed  stigma  pushing 
out  beyond  the  anthers,  which  are  pressed  close  about  it  at  the 
throat  of  the  tube;  between  each  two  anthers  may  be  seen  a little 
deep  passage,  through  which  the  tongues  of  the  moth  or  butterfly  can  be 
thrust  to  reach  the  nectar.  In  a tube,  slit  open,  we  can  see  the  nectar  at 
the  very  bottom  of  it,  and  it  is  sweet  to  the  taste  and  has  a decided  flavor. 
In  this  open  tube  we  may  see  that  the  filaments  of  the  stamens  are  grown 
fast  to  the  sides  of  the  tube  for  much  of  their  length,  enough  remaining 
free  to  press  the  anthers  close  to  the  style.  The  ovary  of  the  pistil  is  a 
green  swelling  at  the  base  of  the  tube ; by  cutting  it  across  we  can  see  it  is 
triangular  in  outline,  and  has  a little  cavity  in  each  angle  large  enough  to 
hold  two  rows  of  the  little,  white,  shining,  unripe  seeds.  Each  of  these 
cavities  is  partitioned  from  the  others  by  a green  wall ; the  partition  is 
marked  by  a suture  on  the  outside  of  the  seed-pod.

Handbook  of  N atur e-Study 


When  the  flower  stalk  first  appears,  it  comes  up  like  a sheathed  sword, 
pointing  toward  the  zenith,  green , veined  lengthwise,  and  with  a noticeable 
thickening  at  each  edge.  As  the  petals  grow,  the  sheath  begins  to  round 
out ; and  then  as  if  to  confuse  those  people  who  are  so  stupid  as  to  believe 
that  plants  do  not  really  do  things,  the  stiff  stem  at  the  base  of  the  sheath 

bends  at  right  angles.  This  brings  a strain 
upon  the  sheath  which  bursts  it,  usually 
along  the  upper  side,  although  sometimes 
it  tears  it  off  completely  at  the  base.  The 
slitted  sheath,  or  spathe,  hangs  around 
the  stem,  wrinkled  and  parchment-like, 
very  like  the  loose  wrist  of  a suede  glove. 
The  stalk  is  a strong  green  tube;  the 
leaves  are  fleshy  and  are  grooved  on  the 
inner  side,  the  groove  being  deep  enough 
to  clasp  part  way  around  the  flower  stem. 
The  number  of  leaves  varies  with  the 
variety,  and  they  are  usually  as  tall  as 
the  flower  stalk.  There  is  one  flower  on  a 
stalk  in  the  daffodils  and  the  poet’s  nar- 
cissus, but  the  jonquils  and  paper-white 
narcissus  have  two  or  more  flowers  on  the 
same  stalk. 

A bed  should  be  prepared  by  digging 
deep  and  fertilizing  with  stable  manure. 
The  bulbs  should  be  planted  in  September 
or  early  October,  and  should  be  from  four 
to  six  inches  apart,  the  upper  end  of  the 
bulbs  at  least  four  inches  below  the  sur- 
face of  the  soil.  They  should  not  be 
disturbed  but  allowed  to  occupy  the  bed 
for  a number  of  years,  or  as  long  as  they 
give  plenty  of  flowers.  As  soon  as  the 
surface  of  the  ground  is  frozen  in  the  win- 
a,  corona  or  crown;  b,  sepals  and  ter,  the  beds  should  be  covered  from  four 
petals  forming  perianth;  c>  corolla  tube;  to  six  inches  in  depth  with  straw-mixed

spathe.  stable  manure,  which  can  be  raked  off 

very  early  in  the  spring. 

The  new  bulbs  are  formed  at  the  sides  of  the  old  one ; for  this  reason 
the  daffodils  will  remain  permanently  planted,  and  do  not  lift  themselves 
out  of  the  ground  like  the  crocuses.  The  leaves  of  the  plant  should  be 
allowed  to  stand  as  long  as  they  will  after  the  flowers  have  disappeared,  so 
that  they  may  furnish  the  bulbs  with  plenty  of  food  for  storing.  The 
seeds  should  not  be  allowed  to  ripen,  as  it  costs  the  plant  too  much 
energy  and  thus  robs  the  bulbs.  The  flowers  should  be  cut  just  as  they 
are  opening.  Of  the  white  varieties,  the  poet’s  narcissus  is  the  most 
satisfactory,  as  it  is  very  hardy  and  very  pretty,  its  corona  being  a shallow, 
flaring,  greenish  yellow  rosette  with  orange-red  border,  the  anthers  of  its 
three  longest  stamens  making  a pretty  center.  No  wonder  Narcissus  bent 
over  the  pool  in  joy  at  viewing  himself,  if  he  was  as  beautiful  a man  as 
the  poet’s  narcissus  is  as  a flower.

LESSON  CLI 

Daffodils,  Jonquils  and  Narcissus 

Leading  thought — The 
daffodil,  jonquil  and  nar- 
cissus are  very  closely  re- 
lated, and  quite  similar. 

They  all  come  from  bulbs 
which  should  be  planted  in 
September;  but  after  the 
first  planting,  they  will 
flower  on  year  after  year, 
bringing  much  brightness 
to  the  gardens  in  the  early 
spring. 

Method — The  fl  o w e r s 
brought  to  school  may  be 
studied  for  form,  and  there 
should  be  a special  study  of 
the  way  the  flower  devel- 
ops its  seed,  and  how  it  is 
propagated  by  bulbs.  The 
work  should  lead  directly 
to  an  interest  in  the  culti- 
vation of  the  plants.  In 
seedsmen’s  catalogues  or 
other  books,  the  children 
will  find  methods  of  plant- 
ing and  cultivating  these 
flowers  in  cities.  Daffodils 
are  especially  adapted  for 
both  window  gardens  and 
school  gardens. 

Observations — i . N ote  the  snape  of  the  flower.  Has  it  any  sepals  ? What 
do  we  call  the  flowers  that  have  their  sepals  colored  like  petals,  thus  form- 
ing a part  of  the  beauty  of  the  flower?  Can  you  see  any  difference  in 
color,  position  and  texture  between  the  petals  and  sepals? 

2.  How  do  the  petal-like  parts  of  these  flowers  look?  How  many  of 
them  are  there?  Do  they  make  the  most  showy  part  of  the  flower? 

3.  What  does  the  central  part  of  the  flower  look  like?  Why  is  it 
called  the  corona,  or  crown?  Is  it  a part  of  the  tube  which  joins  the 
flower  to  the  stem?  Do  the  petals  and  sepals  peel  off  this  tube?  Peel 
them  off  one  flower,  and  see  that  the  tube  is  shaped  like  a trumpet. 

4.  Look  down  into  the  crown  of  the  flower  and  tell  what  you  see. 
Can  you  see  where  the  insect’s  tongue  must  go  to  reach  the  nectar? 

5.  Cut  open  a trumpet  lengthwise  to  find  where  the  nectar  is.  How 
far  is  it  from  the  mouth  of  the  tube  ? How  long  would  the  insect’s  tongue 
have  to  be  to  reach  it  ? What  insects  have  tongues  as  long  as  this  ? 

6.  In  order  to  reach  the  nectar  how  would  an  insect  become  dusted 
with  pollen?  Are  the  stamens  loose  in  the  flower-tube?  Is  the  pistil 
longer  than  the  stamens  ? How  many  parts  to  the  stigma  ? Can  you  see 


Paper-white  narcissus. 


602

how  the  flowers  are  arranged  so  that  insects  can  carry  pollen  from 
flower  to  flower? 

7.  What  is  the  green  swelling  in  the  stem  at  the  base  of  the  trumpet  ? 
Is  it  connected  with  the  style?  Cut  it  across  and  describe  what  you  see. 
How  do  the  young  seeds  look  and  how  are  they  arranged? 

8„  Where  the  flower  stem  joins  the  stalk,  what  do  you  see?  What  is 
this  dry  spathe  there  for?  Are  there  one  or  more  flower  stems  coming 
from  this  spathe  ? 

Describe  the  flower  stalk?  Are  the  leaves  wide  or  narrow?  Are 
they  as  long  as  the  flower  stalk,  are  they  flat,  or  are  they  grooved  to  fit 
around  the  flower  stalk? 

•10.  What  are  the  differences  between  daffodils,  jonquils  and  poet’s 
narcissus?  When  should  the  bulbs  for  these  flowers  be  planted?  Will 
there  be  more  bulbs  formed  around  the  one  you  plant?  Will  the  same 
bulb  ever  send  up  flowers  and  leaves  again?  How  do  the  bulbs  divide  to 
make  new  bulbs  ? 

ii-  How  should  the  bed  for  the  bulbs  be  prepared?  How  near 
together  should  the  bulbs  be  planted?  How  deep  in  the  earth?  How 
protect  them  in  the  North  during  the  winter? 

12.  Why  should  you  not  cut  the  leaves  off  after  the  flowers  have  died? 
Why  should  you  not  let  the  seeds  ripen?  When  should  the  flowers  be  cut 
for  bouquets?  Who  was  Narcissus,  and  why  should  these  early  spring 
flowers  be  named  after  him  ?

“7  emphatically  deny  the  common  notion  that  the  farm  hoy's  life  is  drudgery.  Much  of 
the  work  is  laborious,  and  this  it  shares  with  all  work  that  is  productive;  for  the  easier  the 
job  the  less  it  is  worth  doing.  But  every  piece  of  farm  work  is  also  an  attempt  to  solve  a 
problem,  and  therefore  it  should  have  its  intellectual  interest;  and  the  problems  are  as  many 
as  the  hours  of  the  day  and  as  varied  as  the  face  of  nature.  It  needs  but  the  informing  of  the 
mind  and  the  quickening  of  the  imagination  to  raise  any  constructive  work  above  the  level  of 
drudgery.  It  is  not  mere  dull  work  to  follow  the  plow — 7 have  followed  it  day  after  day — if 
one  is  conscious  of  all  the  myriad  forces  that  are  set  at  work  by  the  breaking  of  the  furrow; 
and  there  is  always  the  landscape,  the  free  fields,  the  clean  soil,  the  rain,  the  promise  of  the 
crops.  Of  all  men's  labor,  the  farmer's  is  the  most  creative.  I cannot  help  wondering  why 
it  is  that  men  will  eagerly  seek  work  in  the  grease  and  grime  of  a noisy  factory,  but  will  recoil 
at  what  they  call  the  dirty  work  of  the  farm.  So  much  are  we  yet  bound  by  tradition!"

THE  TULIP 
Teacher's  Story 

We  might  expect  that  the  Lady  Tulip  would  be  a 
stately  flower,  if  we  should  consider  her  history. 
■She  made  her  way  into  Europe  from  the  Orient 
during  the  sixteenth  century,  bringing  with  her  the 
honor  of  being  the  chosen  flower  of  Persia,  where 
her  colors  and  form  were  reproduced  in  priceless 
webs  from  looms  of  the  most  skilled  weavers.  No 
sooner  was  she  seen  than  worshipped,  and  shortly 
all  Europe  was  at  her  feet. 

A hundred  years  later,  the  Netherlands  was 
possessed  with  the  tulip  mania.  Growers  of  bulbs, 
and  brokers  who  bought  and  sold  them,  indulged  in 
wild  speculation.  Rare  varieties  of  the  bulbs 
became  more  costly  than  jewels,  one  of  the  famous 
black  tulips  being  sold  for  about  $1800.  Since  then, 
the  growing  of  tulips  has  been  one  of  the  noted 
industries  of  the  Netherlands,  and  now  the  bulbs  on 
our  market  are  imported  from  Holland. 

There  are  a great  many  varieties  of  tulips,  and 
their  brilliant  colors  make  our  gardens  gorgeous  in 
early  spring.  Although  this  flower  is  so  prim,  yet  it 
bears  well  close  observation.  The  three  petals,  or  inner  segments  of  the 
perianth,  are  more  exquisite  in  texture  and  in  satiny  gloss  on  their  inner 
surface  than  are  the  three  outer  segments  or  sepals;  each  petal  is  like 
grosgrain  silk,  the  fine  ridges  uniting  at  the  central  thicker  portion.  In  the 
red  varieties,  there  is  a six  pointed  star  at  the  heart  of  the  flower,  usually 
yellow  or  yellow-margined,  each  point  of  the  star  being  at  the  middle  of  a 
petal  or  sepal;  the  three  points  on  the  petals  are  longer  than  those  on  the 
sepals. 

When  the  flower’s  bud  first  appears,  it  is  nestled  down  in  the  center  of 
the  plant,  scarcely  above  the  ground.  It  is  protected  by  three  green 
sepals.  As  it  stretches  up,  the  bud  becomes  larger  and  the  green  of  the 
sepals  takes  on  the  color  of  the  tulip  flower,  until  when  it  opens  there  is 
little  on  the  outside  of  the  sepals  to  indicate  that  they  once  were  green. 
But  they  still  show  that  they  are  sepals,  for  they  surround  the  petals,  each 
standing  out  and  making  the  flower  triangular  in  shape  as  we  look  into  it. 
During  storms  and  dark  days,  the  sepals  again  partially  close  about  the 
flower.

The  seed-vessel  stands  up,  a stout,  three-sided,  pale  green  column  at 
the  center  of  the  flower,  in  some  varieties,  its  three-lobed  yellowish  stigma 
making  a Doric  capital;  in  others,  the  divisions  are  so  curled  as  to  make 
the  capital  almost  Ionian.  The  six  stout,  paddle-shaped  stamens  have 
their  bases  expanded  so  as  to  encircle  completely  the  base  of  the  pistil 
column;  these  wide  filaments  are  narrower  just  below  the  point  where 
the  large  anthers  join.  The  anther  opens  along  each  side  to  discharge  the 
pollen ; however,  the  anthers  flare  out  around  the  seed  vessel  and  do  not 
reach  half  way  to  the  stigma,  which  is  probably  the  tulips’ way  of  inducing 
the  insects  to  carry  their  pollen,  since  the  bees  cannot  reach  the  nectar  at 
the  base  of  the  pistil  without  dusting  themselves  with  pollen. 

The  flower  stem  is  stout,  pale  green,  covered  with  a whitish  bloom. 
The  leaves  are  long,  trough-shaped  and  narrow  with  parallel  veins;  the 
bases  of  the  lower  ones  encircle  the  flower  stem  and  have  their  edges  more 
or  less  ruffled  and  their  tips  recurved ; the  upper  leaves  do  not  completely 
encircle  the  flower  stem  at  their  bases.  The  texture  of  the  leaves  is  some- 
what softer  on  the  inside  than  on  the  outside,  and  both  sides  are  grayish 
green. 


After  the  petals  and  stamens  are  dropped 
the  seed-vessel  looks  like  an  ornamental  tip 
to  the  flower  stem;  it  is  three-sided,  and 
has  within  double  rows  of  seeds  along  each 
angle.  The  seeds  should  not  be  allowed  to 
ripen  as  they  thus  take  too  much  strength 
from  the  bulbs. 

The  bulb  is  formed  of  several  coats,  or 
layers,  each  of  which  extends  upwards  and 
may  grow  into  a leaf;  this  shows  that  the 
bulb  is  made  up  of  leaves  which  are 
thickened  with  the  food  which  is  stored  up 
in  them  during  one  season,  so  as  to  start  the 
plant  growing  early  the  next  spring.  In 
the  heart  of  each  bulb  is  a flower  bud, 
sheltered  and  cuddled  by  the  fleshy  leaf- 
layers  around  it,  which  protect  it  during 
the  winter  and  furnish  it  food  in  the  spring. 
This  structure  of  the  bulb  explains  why  the 
leaves  clasp  the  flower  stem  at  their  bases. 

■ The  true  roots  are  below  the  bulb,  making 
a thick  tassel  of  white  rootlets,  which  reach 
deep  into  the  soil  for  food  and  water. 

Tulips  are  very  accommodating;  they  will  grow  in  almost  any  soil  if 
it  is  well  drained,  so  that  excessive  moisture  may  not  rot  the  bulbs.  In 
preparing  a bed,  it  should  be  rounded  up  so  as  to  shed  water;  it  should 
also  be  worked  deep  and  made  rich.  If  the  soil  is  stiff  and  clayey,  set 
bulbs  only  three  inches  deep,  with  a handful  of  sand  beneath  each.  If  the 
soil  is  mellow  loam,  set  the  bulbs  four  inches  deep  and  from  four  to  six 
inches  apart  each  way,  depending  on  the  size  of  the  bulbs.  They  should 
be  near  enough  so  that  when  they  blossom  the  bed  will  be  covered  ana 
show  no  gaps.  Take  care  that  the  pointed  tip  of  the  bulb  is  upward  and 
that  it  does  not  fall  to  one  side  as  it  is  covered.  October  is  the  usual  time 
for  planting  as  the  beds  are  often  used  for  other  flowers  during  the  summer.

However,  September  is  not  too  early  for  the  planting,  as  the  more  root 
growth  made  before  the  ground  freezes,  the  better;  moreover,  the  early 
buyers  have  best  choice  of  bulbs.  The  beds  should  be  protected  by  a 
mulch  of  straw  or  leaves  during  the  winter,  which  should  be  raked  off  as 
soon  as  the  ground  is  thawed  in  the  spring.  The  blossoms  should  be  cut 
as  soon  as  they  wither,  in  order  that  the  new  bulbs  which  form  within  and 
at  the  sides  of  the  parent  bulb  may  have  all  of  the  plant  food,  which 
would  otherwise  go  to  form  seed.  Tulips  may  be  grown  from  seed,  but  it 
takes  from  five  to  seven  years  to  obtain  blossoms,  which  may  be  quite 
unlike  the  parent  and  worthless.  The  bulblets  grow  to  a size  for  bloom- 
ing in  two  or  three  years ; the  large  one  which  forms  in  the  center  of  the 
plant  will  bloom  the  next  season.

LESSON  CLII 
The  Tulips 

Leading  thought~°~The  tulips  blossom  early,  because  they  have  food 
stored  in  the  bulbs  the  year  before,  ready  to  use  early  in  the  spring. 
There  are  many  varieties ; each  is  worth  studying  carefully,  and  we  should 
all  know  how  to  grow  these  beautiful  flowers. 

Methods— These  observations  may  be  made  upon  tulips  in  school 
gardens  or  bouquets.  The  best  methods  of  cultivating  should  be  a part 
of  the  garden  training.  For  this,  consult  the  seed  catalogues ; also  let  the 
pupils  form  some  idea  of  the  number  of  varieties  from  the  seed  catalogues. 
Water-color  drawings  should  be  a large  factor  in  studying  the  tulip.  The 
red  varieties  are  best  for  beginning  the  study,  and  then  follow  with  the 
other*colors;  note  differences. 

Observations — i.  What  is  the  color  of  your  tulip?  Is  it  all  the  same 
color?  Is  the  bottom  of  the  flower  different  in  color?  W^hat  is  the  pretty 
shape  of  these  different  colors  at  the  heart  of  the  flower? 

2.  Look  at  a tulip  just  opening.  What  causes  it  to  appear  so  tri- 
angular? Can  you  see  that  the  three  sepals  are  placed  outside  the  petals? 
Is  there  any  difference  in  color  between  the  sepals  and  petals  on  the  inside 
On  the  outside?  Are  the  sepals  and  petals  the  same  in  length  and  shape? 
Do  you  know  the  name  given  to  this  arrangement  when  sepals  and  petals 
look  alike  in  color?  Are  the  three  petals  more  satiny  on  the  inside  than 
the  sepals?  Is  the  center  part  of  the  petal  as  soft  as  the  edges? 

3 . When  the  tulip  flower  bud  first  begins  to  show,  where  is  it  ? What 
color  are  the  sepals  which  cover  it?  Describe  the  opening  of  the  flower? 
Do  the  green  sepals  fall  off?  What  becomes  of  them? 

4.  In  the  open  flower,  where  is  the  seed-pod,  and  how  does  it  look? 
How  do  the  anthers  surround  the  seed-pod,  or  ovary?  Describe  the 
anthers,  or  pollen-boxes?  What  color  are  they?  What  color  is  the 
pollen?  Do  the  anthers  reach  up  to  the  stigma,  or  tip  of  seed-pod? 
Where  is  the  nectar  in  tulips?  How  do  the  insects  become  covered  with 
the  pollen  in  reaching  it?  Do  the  flowers  remain  open  during  dark  and 
stormy  days?  Why? 

5.  Describe  the  tulip  stem  and  the  leaves.  Do  the  leaves  completely 
encircle  the  flower  stem  at  the  base?  Are  their  edges  ruffled?  In  the 
sprouting  plant,  do  these  outer  basal  leaves  enfold  the  leaves  which  grow 
higher  on  the  stem?  Are  the  leaves  the  same  color  above  and  below? 
What  shade  of  green  are  they? 

6.  After  the  petals  have  dropped,  study  the  seed-pod.  Cut  it  cross- 
wise and  note  how  many  angles  it  has.  How  are  these  angles  filled? 
Should  tulips  be  allowed  to  ripen  seeds?  Why  not? 

7.  Study  a bulb  of  a tulip.  There  are  outer  and  inner  layers  and  a 
heart.  What  part  of  the  plant  do  the  outer  layers  make?  What  part 
does  the  center  make?  Where  are  the  true  roots  of  the  tulip? 

8.  When' should  tulip  bulbs  be  planted?  How  should  you  prepare 
the  soil?  How  protect  the  bed  during  the  winter?  How  long  would  it 
take  to  grow  the  flowers'  from  the  seed?  Where  are  most  of  our  bulbs 
grown  ? Do  you  know  about  the  history  of  tulips  ?

Pansies. 

Drawn  by  Anna  C.  Stryke. 


THE  PANSY 
Teacher's  Story 

OME  people  are  pansy-faced  and  some  pansies  are  human- 
faced, and  for  some  occult  reason  this  puts  people  and 
pansies  on  a distinctly  chummy  basis.  When  we  analyze 
the  pansy  face,  we  find  that  the  dark  spots  at  the  bases  of 
the  side  petals  make  the  eyes,  the  lines  radiating  from 
them  looking  quite  eyelashy.  The  opening  to  the  nectar- 
tube  makes  the  nose,  while  the  spot  near  the  base  of  the 
lower  petal  has  to  do  for  a mouth,  the  nectar  guiding-lines 
being  not  unlike  whiskers.  Meanwhile,  the  two  upper 
petals  give  a “high -browed”  look  to  the  pansy  counten- 
ance, and  make  it  a wise  and  knowing  little  face. 

The  pansy  nectar  is  hidden  in  the  spur  made  by  the  lower  petal  extend- 
ing behind  the  flower.  The  guiding  lines  on  the  lower  and  side  petals  all 
converge,  pointing  directly  to  the  opening  which  leads  to  this  nectar-well, 
telling  the  secret  to  every  bee  that  flies.  Moreover,  the  broad  lower  petal 
is  a platform  for  the  lady  bee  to  alight  upon,  while  she  probes  the  nectar- 
well  with  her  tongue. 

But  at  the  door  leading  to  the  nectar- well  sits  a little  man ; his  head  is 
green,  he  wears  a white  cape  with  a scalloped,  reddish  brown  collar,  and 
he  sits  with  his  bandy  legs  pushed  back  into  the  spur  as  if  he  were  taking  a 
foot  bath  in  nectar.  This  little  pansy  man  has 
plenty  of  work  to  do;  for  his  mouth,  which  is  large 
and  at  the  top  of  his  green  head,  is  the  stigma.  The 
cape  is  made  of  five  overlapping  stamens,  the 
brown,  scalloped  collar  being  the  anthers;  his  legs 
consist  of  prolongations  of  the  two  lower  stamens. 

And  when  the  bee  probes  the  nectar-well  with  her 
tongue,  she  tickles  the  little  man’s  feet  so  that  his 
head  and  shoulders  wriggle;  and  thus  she  brushes  The  little  pansy-man. 
the  pollen  dust  from  his  collar  against  her  fuzzy 

face,  and  at  the  same  time  his  mouth  receives  the  pollen  from  her  dusty 
coat. 


6o8 


Handbook  of  N ature-Study 


As  the  pansy  matures,  the  little  man  grows  still  more  manlike;  after  a 
time  he  sheds  his  anther  cape,  and  we  can  see  that  his  body  is  the  ribbed 
seed-pod.  He  did  not  eat  pollen  for  nothing,  for  he  is  full  of  growing 
seeds.  Sometimes  the  plush  brushes,  which -are  above  his  head  in  the 
pansy  flower,  become  filled  with  pollen,  and  perhaps  he  gets  a mouthful  of 
it,  although  these  brushes  are  supposed  to  keep  out  intruders. 

The  pansy  sepals,  five  in  number,  are  fastened  at  about  one-third  of 
their  length,  their  heart-shaped  bases  making  a little  green  ruffle  around 
the  stem  where  it  joins  the  flower.  There  is  one  sepal  above  and  two  at 
each  side,  but  none  below  the  nectar-spur.  The  flower  stem  is  quite  short 
and  always  bends  politely  so  the  pansy  can  look  sidewise  at  us  instead  of 
staring  straight  upward.  The  plant  stem  is  angled  and  crooked  and  stout. 
In  form,  the  leaves  are  most  capricious;  some  are  long  and  pointed, 
others  wide  and  rounded.  The  edges  are  slightly  scalloped  and  the  leaf 
may  have  at  its  base  a pair  of  large,  deeply  lobed  stipules.  In  a whole 
pansy  bed  it  would  be  quite  impossible  to  find  two  leaves  just  alike. 

The  pansy  ripens  many  seeds.  The  ribbed  seed-capsule,  with  its  base 
set  comfortably  in  the  faithful  sepals,  finally  opens  in  three  valves  and  the 
many  seeds  are  scattered.  To  send  them  as  far  afield  as  possible,  the 
edges  of  each  valve  of  the  pod  curl  inward,  and  snap  the  seeds  out  as  boys 
snap  apple  seeds  from  the  thumb  and  finger. 

Pansies  like  deep,  rich  and  cool,  moist  soil.  They  are  best  suited  to  a 
northern  climate,  and  prefer  the  shady  side  of  a garden  to  the  full  sunshine. 
The  choice  varieties  are  perpetuated  through  cuttings.  They  may  be 
stuck  in  the  open  ground  in  summer  in  a half-shady  place  and  should  be 
well-watered  in  dry  weather.  All  sorts  of  pansies  are  readily  raised  from 
seed  sown  in  spring  or  early  summer,  and  seedlings,  when  well  established, 
do  not  suffer,  as  a rule,  from  winter  frosts. 

The  general  sowing  for  the  production  of  early  spring  bloom  is  made 
out  of  doors  in  August,  while  seeds  sown  indoors  from  February  to  June 
will  produce  plants  to  flower  intermittently  during  the  late  summer  and 
fall  months.  When  sowing  pansy  seed  in  August,  sow  the  seed  broadcast 
in  a seed-bed  out  of  doors,  cover  very  lightly  with  fine  soil  or  well-rotted 
manure,  and  press  the  seed  in  with  a small  board;  then  mulch  the  seed- 
bed with  long,  strawy  horse  manure,  from  which  the  small  particles  have 
been  shaken  off,  to  the  thickness  of  one  inch,  so  as  to  have  the  soil  well  and 
evenly  covered.  At  the  end  of  two  weeks  the  plants  will  be  up.  Then 
remove  the  straw  gradually,  a little  at  a time,  selecting  a dull  day  if  possi- 
ble . Keep  the  bed  moist . 

If  the  pansies  are  allowed  to  ripen  seeds  the  season  of  bloom  will  be 
short,  for  when  its  seeds  are  scattered  the  object  of  the  plant’s  life  is 
accomplished . Besides,  the  plant  has  not  vitality  enough  to  perfect  seeds 
and  continue  its  bloom,  and  flowers  borne  with  the  forming  seeds  are 
smaller  than  the  earlier  ones.  But  if  the  flowers  are  kept  plucked  as  they 
open,  the  plants  persistently  put  forth  new  buds.  The  plucked  flowers 
will  remain  in  good  condition  longer  if  picked  in  the  early  morning  before 
the  bees  begin  paying  calls,  for  a fertilized  flower  fades  more  quickly  than 
one  which  has  received  no  pollen.

LESSON  CLIII 
The  Pansy 

Leading  thought — The  pansy  is  a member  of  the  violet  family.  The 
flower  often  resembles  a face;  the  colors,  markings  and  fragrance  all 
attract  the  bees,  who  visit  it  for  the  nectar  hidden  in  the  spur  of  the  lower 
petal. 

Method — The  children  naturally  love  pansies  because  of  the  reserm 
blance  of  these  flowers  to  quaint-  little  faces.  They  become  still  more 
interested  after  they  see  the  little  man  with  the  green  head,  which  appears 
in  the  flower  as  it  fades.  A more  practical  interest  may  be  cultivated  by 
studying  the  great  numbers  of  varieties  in  the  seed  catalogs  and  learning 
their  names.  This  is  one  of  the  studies  which  leads  directly  to  gardening. 
There  are  many  beautiful  pansy  poems  which  should  be  read  in  connec- 
tion with  the  lesson. 

Observations — i . How  does  the  pansy  flower  resemble  a face  ? Where 
are  the  eyes?  The  nose?  The  mouth?  How  many  petals  make  the 
pansy  forehead  ? The  cheeks  ? The  chin  ? 

2.  Where  is  the  nectar  in  the  pansy?  Which  petal  forms  the  nectar- 
tube  ? 

3 . Describe  how  a bee  gets  the  nectar.  Where  does  she  stand  while 
probing  with  her  tongue? 

4.  Where  is  the  pollen  in  the  pansy?  What  is  the  peculiar  shape  of 
the  anthers  ? How  do  the  two  lower  stamens  differ  in  form  from  the  three 
upper  ones  ? 


6io 


Handbook  of  N atur e-Study 


5 . Where  is  the  stigma  ? Does  the  bee’s  tongue  go  over  it  or  under  it 
to  reach  the  nectar?  Describe  the  pansy  arrangement  for  dusting  the  bee 
with  pollen  and  for  getting  pollen  from  her  tongue. 

6.  Observe  the  soft  little  brushes  at  the  base  of  the  two  side  petals. 
What  do  you  think  they  are  for? 

7.  Take  a fading  flower;  remove  the  petals,  and  see  the  little  man 
sitting  with  his  crooked  legs  in  the  nectar-tube.  What  part  of  the  flower 
makes  the  man’s  head?  What  parts  form  his  cape?  Of  what  is  his 
pointed,  scalloped  collar  formed? 

8.  How  many  sepals  has  the  pansy?  Describe  them.  How  are  they 
attached?  When  the  flower  fades  and  the  petals  fall,  do  the  sepals  also 
fall? 

9.  Where  in  the  flower  is  the  young  seed-pod?  Describe  how  this 
looks  after  the  petals  have  fallen. 

20.  Describe  how  the  seed-pod  opens.  How  many  seeds  are  there  in 
it?  How  are  they  scattered  ? 

11.  Study  the  pansy  stem.  Is  it  solid?  Is  it  smooth  or  rough?  Is  it 
curved?  Does  it  stand  up  straight  or  partially  recline  on  the  ground? 

12.  Take  a pansy  leaf  and  sketch  it  with  the  stipules  at  its  base. 
Can  you  find  two  pansy  leaves  exactly  alike  in  shape,  color  and  size? 

13.  At  what  time  should  the  pansy  seed  be  planted?  How  should  the 
soil  be  prepared  ?

I dropped  a seed  into  the  earth . It  grew , and  the  plant  was  mine . 

It  was  a wonderful  thing,  this  plant  of  mine . I did  not  know  its  name,  and  the  plant 
did  not  bloom . All  I know  is  that  I planted  something  apparently  as  lifeless  as  a grain  of 
sand  and  there  came  forth  a green  and  living  thing  unlike  the  seed , unlike  the  soil  in  which  it 
stood,  unlike  the  air  into  which  it  grew.  No  one  could  tell  me  why  it  grew , nor  how.  It  had 
secrets  all  its  own , secrets  that  baffle  the  wisest  men;  yet  this  plant  was  my  friend.  It  faded 
when  I withheld  the  light,  it  wilted  when  I neglected  to  give  it  water  , it  flourished  when  I sup- 
plied its  simple  needs.  One  week  I went  away  on  a vacation,  and  when  I returned  the  plant 
was  dead;  and  I missed  it. 

Although  my  little  plant  had  died  so  soon,  it  had  taught  me  a lesson;  and  the  lesson  is 
ihat.it  is  worth  while  to  have  a plant. — The  Nature-Study  Idea,  L.  H.  Bailey.

THE  BLEEDING  HEART 


Teacher's  Story 

For  the  intricate  structure  of  this  type  of  flower,  the  bleeding  heart  is 
much  more  easily  studied  than  its  smaller  wild  sisters,  the  Dutchman’s 
breeches  or  squirrel  corn ; therefore  it  is  well  to  study  these  flowers  when 
we  find  them  in  profusion  in  our  gardens,  and  the  next  spring  we  may 
study  the  wildwood  species  more  understandingly. 

The  flowers  of  the  bleeding  heart  are  beautiful  jewel-like  pendants 
arranged  along  the  stem  according  to  their  age ; the  mature  flower,  ready 
to  shed  its  petals,  is  near  the  main  stem,  while  the  tiny  unopened  bud  is 
hung  at  the  very  tip,  where  new  buds  are  constantly  being  formed  during  a 

long  season  of  bloom.  This 
flower  has  a strange  modifi- 
cation of  its  petals;  the  two 
pink  outer  ones,  which  make 
the  heart,  are  really  little 
pitchers  with  nectar  at  their 
bottoms,  and  although  they 
hang  mouth  downwards  the 
nectar  does  not  flow  out. 
When  these  outer  petals  are 
removed,  we  can  see  the 
inner  pair  placed  opposite  to 
them,  the  two  of  them  close 
together  and  facing  each 
other  like  two  grooved  ladles. 
Just  at  the  mouth  of  the 
pitchers  these  inner  petals 
are  almost  divided  cross- 
wise; and  the  parts  that  extend  beyond  are  spoon-shaped,  like  the  bowls' 
vf  two  spoons  which  have  been  pinched  out  so  as  to  make  a.  wide,  flat

ridge  along  their  centers.  These  spoon-bowls  unite  at  the  tip,  and 
between  them  they  clasp  the  anthers  and  stigma.  Special  attention 
should  be  given  to  the  division  between  the  two  portions  of  these  inner 
petals;  for  it  is  a hinge,  the  workings  of  which  are  of  much  importance  to 
the  flower.  On  removing  the  outer  petals,  we  find  a strange  framework 
around  which  the  heart-shaped  part  of  the  flower  seems  to  be  modeled. 
These  are  filaments  of  the  stamens  grouped  in  threes  on  each  side;  the 
two  outer  ones  of  each  group  are  widened  into  frills  on  the  outer  edge, 
while  the  central  one  is  stiffer  and  narrower.  At  the  mouth  of  the 
pitchers  all  these  filaments  unite  in  a tube  around  the  style ; near  the 
stigma  they  split  apart  into  six  short,  white,  threadlike  filaments,  each 
bearing  a small,  brilliant  yellow  anther.  So  close  together  are  these 
anthers  that  they  are  completely  covered  by  the  spoon-bowls  made  by 
the  inner  petals,  the  pollen  mass  being  flat  and  disklike.  During  the 
period  when  the  pollen  is  produced,  the  stigma  is  flat  and  immature;  but 
after  the  pollen  is  shed,  it  becomes  rounded  into  lobes  ready  to  receive 
pollen  from  other  flowers. 

Although  the  description  of  the  plant  of  this  flower  is  most  complex 
and  elaborate,  the  workings  of  the  flower  are  most  simple.  As  the  nectar- 
pitchers  hang  mouth  down,  the  bee  must  cling  to  the  flower  while  probing 
upward.  In  doing  this  she  invariably  pushes  against  the  outside  of  the 
spoon-bowls,  and  the  hinge  at  their  base  allows  her  to  push  them  back 
while  the  mass  of  pollen  is  thrust  against  her  body;  as  this  hinge  works 
both  ways,  she  receives  the  pollen  first  on  one  side  and  then  on  the  other, 
as  she  probes  the  nectar-pitchers.  And  perhaps  the  next  flower  she  visits 
may  have  shed  its  pollen,  and  the  swing  door  will  uncover  the- ripe  stigma 
ready  to  receive  the  pollen  she  brings. 

The  sepals  are  two  little  scales  opposite  the  bases  of  the  outer  petals. 
Before  the  flower  opens,  the  “spouts  of  the  nectar-pitchers”  are  clamped 
up  on  either  side  of  the  spoon-bowls,  as  if  to  keep  everything  safe  until 
the  right  moment  comes;  at  first  they  simply  spread  apart,  but  later 
curve  backward.  The  seed-pod  is  long  and  narrow,  and  in  cross-section 
is  seen  to  contain  two  compartments  with  seeds  growing  on  every  side  of 
the  partition. 

The  bleeding  heart  is  a native  of  China,  and  was  introduced  into  Europe 
about  the  middle  of  the  last  century.

LESSON  CLIV 
The  Bleeding  Heart 

Leading  thought — The  bleeding  heart  flower  has  its  pollen  and  stigma 
covered  by  a double  swing  door,  which  the  bees  push  back  and  forth  when 
they  gather  the  nectar. 

Method — Bring  a bouquet  of  the  bleeding  heart  to  the  schoolroom,  and 
let  each  pupil  have  a stem  with  its  flowers  in  all  stages.  From  this  study, 
encourage  them  to  watch  these  flowers  when  the  insects  are  visiting  them. 

Observations — i.  How  are  these  flowers  supported?  Do  they  open 
upward  or  downward?  Can  you  see  the  tiny  sepals? 

2.  How  many  petals  can  you  see  in  this  flower?  What  is  the  shape 
of  the  two  outer  petals?  How  do  they  open?  Where  is  the  nectar 
developed  in  these  petals?

3.  Take  off  the  two  outer  petals  and  study  the  two  inner  ones. 
What  is  their  shape  near  the  base  ? How  are  their  parts  shaped  which 
project  beyond  the  outer  petals?  What  does  the  spoon-end  of  these 
petals  cover?  Can  you  find  the  hinge  in  these  petals? 

4.  Where  are  the  stamens?  How  many  are  there?  Describe  the 
shape  of  the  stamens  near  the  base.  How  are  they  united  at  the  tip  ? 

5.  Where  is  the  stigma?  The  style?  The  ovary? 

6.  Supposing  a bee  is  after  the  nectar,  where  must  she  rest  while 
probing  for  it?  Can  she  get  the  nectar  without  pushing  against  the  flat 
projecting  portion  of  the  inner  petals?  When  she  pushes  these  spoon- 
bowls  back,  what  happens?  Does  she  get  dusted  with  pollen ? After  she 
leaves,  does  the  door  swing  back  ? Suppose  she  visits  another  flower  which 
has  shed  its  pollen,  will  she  carry  pollen  to  its  stigma?  Does  she  have  to 
work  the  hinged  door  to  do  this  ? 


THE  POPPIES 
Teacher's  Story 

ERHAPS  we  might  expect  that  a plant  which 
gives  strange  dreams  to  those  who  eat  of  its 
juices  should  not  be  what  it  seems  in  appear- 
ance. I know  of  nothing  so  deceptive  as  the 
appearance  of  the  poppy  buds,  which,  rough 
and  hairy,  droop  so  naturally  that  it  seems  as 
if  their  weight  must  compel  the  stem  to  bend; 
and  yet,  if  we  test  it,  we  find  the  stem  is  as  stiff 
as  if  made  of  steel  wire.  Moreover,  the  flower 
and  the  ripened  seed-capsule  must  be  far  heavier  than  the  bud;  and 
yet,  as  soon  as  the  flower  is  ready  to  open,  the  stem  straightens  up, 
although  it  does  not  always  remove  the  traces  of  the  crook;  and  after 
the  capsule  is  full  of  ripened  seed,  the  stem  holds  it  up  particularly  stiff, 
as  if  inviting  the  wind  to  shake  out  the  seeds. 

The  rough  covering  of  the  bud  consists  of  two  sepals,  as  can  be  easily 
seen ; but  if  we  wish  to  see  the  poppy  shed  its  sepals,  we  must  get  up  in  the 
morning,  for  the  deed  is  usually  done  as  soon  as  the  first  rays  of  the  early 
sun  bring  their  message  of  a fair  day.  The  sepals  break  off  at  their  base 
and  fall  to  the  ground.  The  two  opposite  outer  petals  unfold,  leaving  the 


Poppies.

two  inner  petals  standing  erect  and  on  guard  about  the  precious  pollen, 
until  the  sunshine  folds  them  back.  An  open  poppy,  when  looked  at 
below,  shows  two  petals,  each  semicircular,  and  overlapping  each  other 
slightly;  looked  at  from  above,  we  see  two  petals,  also  half  circles,  set  at 
right  angles  to  the  lower  two,  and  divided  from  each  other  by  the  pistil. 

The  pistil  of  the  poppy  is,  from  the  beginning,  a fascinating  box.  At 
first,  it  is  a vase  with  a round,  circular  cover,  upon  which  are  ridges,  placed 
like  the  spokes  of  a wheel.  If  these  ridges  are  looked  at  with  a lens, 
particles  of  pollen  may  be  seen  adhering  to  them;  this  fact  reveals  the

Stryke. 


secret  that  each  ridge  is  a stigma,  and  all  of  these  radiating  stigmas  are 
joined  so  as  better  to  catch  the  pollen.  In  a circle  of  fringe  about  the 
pistil  are  the  stamens.  In  the  study  of  the  stamens,  we  should  note 
whether  their  filaments  expand  or  dilate  near  the 
anthers,  and  we  should  also  note  the  color  of  the  masses 
of  pollen  which  crowd  out  from  the  anthers. 

Despite  the  many  varieties  of  poppies,  there  are  only 
four  species  commonly  cultivated.  The  opium  poppy 
has  upon  its  foliage  a white  bloom,  the  filaments  of  its 
stamens  are  dilated  at  the  top,  and  its  seed-capsule  is 
smooth.  The  oriental  poppy  has  all  of  these  characters, 
except  that  its  foliage  is  green  and  not  covered  with 
bloom.  Its  blossom  is  scarlet  and  very  large  and  has 
a purple  center  in  the  petals  and  purple  stamens;  it 
has  three  sepals.  Its  flower  stalks  are  stout  and  leafy. 
The  corn  poppy,  which  grows  in  the  fields  of  Europe,  is  a 
weed  we  gladly  cultivate.  This,  naturally,  has  red 
petals  and  is  dark  at  the  center  of  the  flower;  but  it  has 
been  changed  by  breeding  until  now  we  have  many 
varieties.  Its  foliage  is  finely  cut  and  very  bristly  or 
hairy.  Its  seed-capsule  is  not  bristly.  To  see  this 
poppy  at  its  best,  we  should  visit  northern  Italy  or  southern  France  in 
late  May,  where  it  makes  the  grain  fields  gorgeous.  This  is  the  origin a> 
parent  of  all  the  Shirley  poppies.  The  Arctic,  or  Iceland  poppy,  has  flow- 
ers of  satiny  texture  and  finely  crumpled;  its  colors  are  yellow,  orange  or 
white,  but  never  scarlet  like  the  corn  poppy ; it  has  no  leaves  on  its  flower 
stem,  and  its  seed-capsule  is  hairy.  Of  these  four  species,  the  opium 
poppy  and  the  corn  poppy  are  annuals,  while  the  Arctic  and  the  Oriental 
species  are  perennials. 

The  bees  are  over-fond  of  the  poppy  pollen  and  it  is  a delight  to  watch 
the  fervor  with  which  they  simply  wallow  in  it,  brushing  off  all  of  the 
grains  possible  onto  their  hairy  bodies.  I have  often  seen  a honey-bee 
seize  a bunch  of  the  anthers  and  rub  them  against  the  under  side  of  her 
body,  meanwhile  standing  on  her  head  in  an  attitude  of  delirious  joy.  As 
showing  the  honey-bee’s  eye  for  color,  I have  several  times  seen  a bee  drop 
to  the  ground  to  examine  a red  petal  which  had  fallen.  This  was  plain 
evidence  that  she  trusted  to  the  color  to  guide  her  to  the  pollen. 

But  perhaps  it  is  the  development  of  the  poppy  seed-capsule  which 
we  find  the  most  interesting  of  the  poppy  performances.  After  fertiliza- 
tion, the  stigma-disk  develops  a scalloped  edge,  a stigma  rounding  out  the 
point  of  each  scallop ; and  a sharp  ridge,  which  continues  the  length  of  the 
globular  capsule,  runs  from  the  center  of  each  scallop.  If  examined  on 
the  inside,  it  will  be  seen  that  the  ridge  on  the  capsule  is  the  edge  of  a 


Cultivated-Plant  Study 


6i§ 

partition  which  extends  only  part  way  toward  the  center  of  the  capsule. 
On  these  partitions,  the  little  seeds  are  grown  in  great  profusion,  and  when 
they  ripen,  they  fall  together  in  the  hollow  center  of  the  seed-box.  But 
how  are  they  to  get  out?  This  is  a point  of  interest  for  the  children  to 
observe,  and  they  should  watch  the  whole  process.  Just  beneath  the 
stigma-disk,  and  between  each  two  of  the  sharp  ridges,  the  point  loosens; 
later,  it  turns  outward  and  back,  leaving  a hole  which  leads  directly  into 
the  central  hollow  portion  of  the  capsule.  The  way  these  points  open  is  as 
pretty  a story  as  I know  in  flower  history.  This  beautiful  globular  cap 
sule,  with  its  graceful  pedestal  where  it  joins  the  stem,  is  a seed-shaker 
instead  of  a salt  or  pepper-shaker.  Passing  people  and  animals  push 
against  it  and  the  stiff  stem  bends  and  then  springs  back,  sending  a little 
shower  of  seeds  this  way  and  that;  or  a wind  sways  the  stalk,  and  the 
seeds  are  sown,  a few  at  a time,  and  in  different  conditions  of  season  and 
weather.  Thus,  although  the  poppy  puts  all  her  eggs  in  one  basket,  she 
sends  them  to  market  a few  at  a time.  The  poppy  seed  is  a pretty  object, 
as  seen  through  the  lens.  It  is  shaped  like  a round  bean,  and  is  covered 
with  a honeycomb  network. 


LESSON  CLV 
The  Poppy 

Leading  thought — The  poppies  shed  their  sepals  when  the  flowers  ex- 
pand; they  offer  quantities  of  pollen  to  the  bees,  which  are  very  fond  of  it. 
The  seed-capsule  develops  holes  around  the  top,  through  which  the  seeds 
are  shaken,  a few  at  a time. 

Method — It  is  best  to  study  these  flowers  in  the  garden,  but  the  lesson 
may  be  given  if  some  of  the  plants  with  the  buds  are  brought  to  the  school- 
room, care  being  taken  that  they  do  not  droop.  If  the  teacher  thinks 
wise,  the  pupils  might  prepare  an  English  theme  on  the  subject  of  the 
opium  poppy  and  the  terrible  effects  of  opium  upon  the  eastern  nations. 

Observations — i.  Look  Ft  the  bud  of  the  poppy;  how  is  it  covered? 
How  many  sepals?  Can  you  see  where  they  unite?  Is  the  stem  bent 
because  the  bud  is  heavy?  What  happens  to  this  crook  in  the  stem 
when  the  flower  opens?  Does  the  crook  always  straighten  out  com- 
pletely ? 

2.  Describe  how  the  poppy  sheds  its  sepals.  At  what  time  of  day  do 
the  poppies  usually  open  ? 

3.  Look  at  the  back  of,  or  beneath,  an  open  flower.  How  many 
petals  do  you  see?  How  are  they  arranged?  Look  at  the  base  of  the 
flower.  How  many  petals  do  you  see?  How  are  they  arranged  in  rela- 
tion to  the  lower  petals  and  to  the  pistil? 

4.  Look  at  the  globular  pistil.  Describe  the  disk  which  covers  it. 
How  many  ridges  on  this  disk?  How  are  they  arranged?  Look  at  the 
ridges  with  a lens  and  tell  what  they  are. 

5.  Look  at  the  stamens.  How  are  they  arranged?  Describe  the 
anthers — their  color,  and  the  color  of  the  pollen.  Watch  the  bees  work- 
ing on  the  poppies,  and  note  if  they  are  after  nectar  or  pollen. 

6.  Find  all  the  varieties  of  poppies  possible,  and  note  the  colors  of  the 
petals  on  the  outside,  the  inside  and  at  the  base ; of  the  stamens,  including 
filaments,  anthers  and  pollen;  of  the  pistil-disk  and  ovary.  Sketch  the

poppy  opened,  and  also  in  the  bud.  Sketch  a petal,  a stamen  and  the 
pistil,  in  separate  studies. 

7.  Study  the  poppy  seed-box  as  it  ripens.  How  does  the  stigma-disk 
look?  What  is  the  shape  of  the  capsule  below  the  disk?  Is  it  ridged? 
What  relation  do  its  ridges  bear  to  the  stigma  ridges  on  the  disk?  Cut  a 
capsule  open,  and  note  what  these  ridges  on  the  outside  have  to  do  with 
the  partitions  inside.  Where  are  the  seeds  borne? 

8.  Note  the  development  of  the  holes  beneath  the  edge  of  the  disk  of 
the  poppy  capsule.  How  are  they  made?  What  are  they  for?  How 
are  the  seeds  shaken  from  these  holes?  What  shakes  the  poppy  seed-box 
and  helps  sow  the  seeds?  Look  at  a seed  through  a lens,  and  describe  its 
form  and  decoration. 

9.  Notice  the  form  of  the  poppy  leaf,  and  note  whether  it  is  hairy  or 
covered  with  bloom.  What  is  there  peculiar  about  the  smell  of  the  poppy 
plant?  Where  do  poppies  grow  wild? 

10.  Is  the  slender  stem  smooth  or  grooved  and  hairy?  Is  it  solid  or 
hollow? 

11.  When  a stem  or  leaf  is  pierced  or  broken  off,  what  is  the  color  of 
the  juice  which  exudes?  Does  this  juice  taste  sweet  or  bitter  and  un- 
pleasant? Do  you  know  what  harmful  drug  is  manufactured  from  the 
juice  of  one  species  of  poppy?  What  countries  cultivate  and  use  it  most 
extensively  ? 


THE  CALIFORNIA  POPPY 

Teacher's  Story 

OUGH  this  brilliant  flower  blossoms 
cheerfully  for  us  in  our  Eastern  gardens,  we 
can  never  understand  its  beauty  until  we  see 
it  glowing  in  masses  on  the  California  foot- 
hills. We  can  easily  understand  why  it  was 
selected  as  the  flower  of  that  great  State, 
since  it  burnished  with  gold  the  hills,  above 
the  gold  buried  below;  and  in  that  land  that 
prides  itself  upon  its  sunshine,  these  poppies 
seem  to  shine  up  as  the  sun  shines  down. 
The  literature  of  California,  and  it  has  a 
noble  literature  of  its  own,  is  rich  in  tributes  to  this  favored  flower. 
There  is  a peculiar  beauty  in  the  contrast  between  the  shining  flower 
and  its  pale  blue-green,  delicate  masses  of  foliage.  Although  it 
is  called  a poppy  and  belongs  to  the  poppy  family,  yet  it  is  not  a true 
poppy,  but  belongs  to  a genus  named  after  a German  who  visited 
California  early  in  the  nineteenth  century,  accompanying  a Russian 
scientific  expedition;  this  German’s  name  was  Eschscholtz,  and  he,  like 
all  visitors,  fell  in  love  with  this  brilliant  flower,  and  in  his  honor  it  was 
named  Eschscholtzia  (es-sholts-ia)  californica.  This  is  not  nearly  so 
pretty,  nor  so  descriptive,  as  the  name  given  to  this  poppy  by  the  Spanish 
settlers  on  the  Pacific  Coast,  for  they  called  it  Copa-de-oro,  cups  of  gold. 

The  bud  of  the  Eschscholtzia  is  a pretty  thing;  it  stands  erect  on  the 
slender,  rather  long  stem,  which  flares  near  the  bud  to  an  urnlike  pedestal 


Cultivated-Plant  Study 


617 


with  a slightly  ruffled  rim,  on 
which  the  bud  is  set.  This 
rim  is  often  pink  above,  and 
remains  as  a pretty  base  for 
the  seed-pod.  But  in  some 
garden  varieties,  the  rim  is 
lacking.  The  bud  itself  is 
covered  with  a peaked  cap, 
like  a Brownie’s  toboggan  cap 
stuffed  full  to  the  tip.  It  is 
the  shape  of  an  old-fashioned 
candle  extinguisher ; it  is  pale 
green,  somewhat  ribbed,  and 
has  a rosy  tip ; it  consists  of 
two  sepals,  which  have*been 
sewed  together  by  Mother 
Nature  so  skillfully  that  we 
cannot  see  the  seams.  One 
of  the  most  interesting  per- 
formances to  watch  that  I 
know,  is  the  way  this  poppy 
takes  off  its  cap  before  it 
bows  to  the  world . Like  magic 
the  cap  loosens  around  the 
base;  it  is  then  pushed  off  by 
the  swelling  expanding  petals 
until  completely  loosened,  and 
finally  it  drops. 

The  petals  are  folded  under 
the  cap  in  an  interesting 
manner.  The  outer  petal  en- 
folds all  the  others  as  closely 
as  it  can,  and  its  mate  within  it 
enfolds  the  other  two,  and  the  inner  two  enfold  the  stamens  with  their 
precious  gold  dust.  When  only  partially  opened,  the  petals  cling  pro- 
tectingly  about  the  many  long  stamens ; but  when  completely  opened,  the 
four  petals  flare  wide,  making  a flower  with  a golden  rim  and  orange 
center,  although  among  our  cultivated  varieties  they  range  from  orange 
to  an  anaemic  white.  To  one  who  loves  them  in  their  glorious  native 
hues,  the  white  varieties  seem  almost  repulsive.  Compare  one  of  these 
small,  pale  flowers  with  the  great,  rich,  orange  ones  that  glorify  some 
favored  regions  in  the  Mojave  Desert,  and  we  feel  the  enervating  and 
decadent  influence  of  civilization. 

The  anthers  are  many  and  long,  and  are  likely  to  have  a black  dot  on 
the  short  filament;  at  first,  the  anthers  stand  in  a close  cluster  at  the 
center  of  the  flower,  but  later  they  flare  out  in  a many  pointed  star. 
Often,  when  the  flowers  first  open,  especially  the  earlier  ones,  the  stigmas 
cannot  be  seen  at  all;  but  after  a time  the  three,  or  even  six  stigmas, 
spread  wide  athwart  the  flower  and  above  the  stamen-star,  where  they 
may  receive  pollen  from  the  visiting  insects.  The  anthers  give  abund- 
ance of  pollen,  but  there  is  said  to  be  no  nectary  present.  This  flower  is  a 
good  guardian  of  its  pollen,  for  it  closes  during  the  nights  and  also  on  dark 


California  poppy.

Handbook  of  N atur e-Study 


and  rainy  days,  only  exposing  its  riches  when  the  sunshine  insures  insect 
visitors.  It  closes  its  petals  in  the  same  order  in  which  they  were  opened 
in  our  Eastern  gardens,  although  there  are  statements  that  in  California, 
each  petal  folds  singly  around  its  own  quota  of  anthers.  The  insects  in 
California  take  advantage  of  the  closing  petals  and  often  get  a night’s 
lodging  within  them,  where  they  are  cozily  housed  with  plenty  of  pollen 
for  supper  and  breakfast ; and  they  pay  their  bill  in  a strange  way  by 
carrying  off  as  much  of  the  golden  meal  as  adheres  to  them,  just  as  the 
man  who  weighs  gold-dust  gets  his  pay  from  what  adheres  to  the  pan 
of  his  scales. 

After  the  petals  fall,  the  little  pod  is  very  small,  but  its  growth  is  as 
astonishing  as  that  of  Jack’s  beanstalk;  it  finally  attains  a slim  length 
of  three  inches,  and  often  more.  It  is  grooved,  the  groove  running 
straight  from  its  rimmed  base  to  its  rosy  tip;  but  later  a strange 
twisting  takes  place.  If  we  open  one  of  these  capsules,  lengthwise,  we 
must  admire  the  orderly  way  in  which  the  little  green  seeds  are  fastened 
by  delicate  white  threads,  in  two  crowded  rows,  the  whole  length  of 
the  pod. 

The  leaf  is  delicately  cut  and  makes  the  foliage  a fine  mass,  but  each 
leaf  is  quite  regular  in  its  form.  It  has  a long,  flattened  petiole,  which 
broadens  and  clasps  the  stem  somewhat  at  its  base.  Its  blade  has  five 
main  divisions,  each  of  which  is  deeply  cut  into  fingerlike  lobes.  The 
color  of  this  foliage  and  its  form  show  adaptations  to  desert  conditions. 

This  plant  has  a long,  smooth  tap  root,  especially  adapted  for  storing 
food  and  moisture  needed  during  the  long,  dry  California  summers;  for  it 
is  perennial  in  its  native  state,  although  in  the  wintry  East,  we  plant  it  as 
an  annual. 

LESSON  CLVI 
The  California  Poppy 

Leading  thought — The  California  poppy  is  a native  of  California.  It 
blossoms  during  the  months  of  February,  March  and  April  in  greatest 
abundance.  It  is  found  in  the  desert  as  well  as  among  the  foothills. 

. Method — If  possible,  the  students  should  study  this  in  the  garden.  In 
the  East,  it  flowers  until  frost  comes,  and  affords  a delightful  subject  for  a 
September  lesson.  In  California  it  should  be  studied  in  the  spring,  when 
the  hills  are  covered  with  them.  But  the  plant  may  be  brought  into  the 
schoolroom,  root  and  all,  and  placed  in  a jar,  under  which  conditions  it 
will  continue  to  blossom. 

Observations — i.  Look  at  the  California  poppy  as  a whole  and  tell,  if 
you  can,  why  it  is  so  beautiful  when  in  blossom. 

2.  Look  at  the  flower  bud.  What  sort  of  a stem  has  it?  What  is 
the  shape  of  the  stem  just  below  the  bud?  What  is  the  color  of  the  little 
rim  on  which  the  bud  rests?  What  peculiarity  has  this  bud ? Describe 
the  little  cap. 

3.  Watch  a flower  unfold.  What  happens  to  the  “toboggan  cap?” 
How  does  the  bud  look  after  the  cap  is  gone?  What  is  its  appearance 
when  the  petals  first  open?  When  they  are  completely  open? 

4.  Describe  the  anthers.  How  do  they  stand  when  the  flower  first 
opens  ? How  later  ? Can  you  see  the  stigmas  at  first  ? Describe  them  as 
they  look  later. 


Cultivated-Plant  Study  619 

5.  Does  the  poppy  remain  open  at  night?  Does  it  remain  open 
during  cloudy  or  rainy  weather  ? Why  ? 

6.  Do  the  petals  have  the  same  position  that  they  did  in  the  bud? 
As  the  flower  matures,  note  how  each  petal  curls.  Do  they  all  fall  at 
once?  Are  there  any  anthers  left  after  the  petals  fall? 

7.  How  does  the  little  pod  look  when  the  petals  first  fall?  What 
happens  to  it  later?  Note  the  little  rim  at  its  base.  Cut  the  seed-pod 
open  lengthwise,  examine  the  seeds  with  a lens,  and  describe  how  they  are 
fastened  to  the  sides  of  the  pod.  Are  the  ribs  straight  from  end  to  end  in 
the  pod  at  first?  Do  they  remain  in  this  position?  How  does  the  pod 
open  and  scatter  its  seeds? 

8.  Study  the  leaf  of  this  California  poppy.  Describe  how  it  joins  the 
stem.  Sketch  a leaf  showing  its  chief  divisions  into  leaflets  and  how  each 
leaflet  is  divided.  Note  that  the  juice  of  the  stem  has  the  peculiar  odor  of 
muriatic  acid. 

9.  Look  at  the  root.  Do  you  think  it  is  fitted  to  sustain  the  plant 
through  a long,  dry  summer?  What  kind  of  summers  do  they  have  in 
California?  Where  does  the  poppy  grow  wild? 

10.  Read  all  the  accounts  you  can  find  of  the  California  poppy,  and 
write  a little  theme  describing  why  it  was  chosen  as  the  flower  of  that  great 
State,  and  how  it  came  by  its  name. 


In  a low  brown  meadow  on  a day 
Down  by  the  autumn  sea, 

I saw  a flash  of  sudden  light 
In  a sweep  of  lonely  gray; 

As  if  a star  in  a clouded  night 
One  moment  had  looked  on  me 
And  then  withdrawn;  as  if  the  spring 
Had  sent  an  oriole  back  to  sing 
A silent  song  in  color,  where 
Other  silence  was  too  hard  to  bear. 

I found  it  and  left  it  in  its  place, 

The  sun-born  flower  in  cloth  of  gold 
That  April  owns,  but  cannot  hold 
From  spending  its  glory  and  its  grace 
On  months  that  always . love  it  less, 

But  take  its  splendid  alms  in  their  distress. 

Back  I went  through  the  gray  and  the  brown, 

Through  the  weed-woven  trail  to  the  distant  town; 

The  flower  went  with  me,  fairly  wrought 
Into  the  finest  fiber  of  my  thought.

THE  NASTURTIUM 
Teacher's  Story 

“ Little  warriors,  brave  and  fearless,  with  shields  of  emerald 
green, 

Are  climbing  over  fence  rails,  and  everywhere  are  seen 
Looking  down  on  every  side,  while  her  brave  Nasturtium 
army, 

Queen  Nature  views  with  pride." 

— Ray  Laurance. 


It  is  quite  fitting  that  the  nasturtium  leaves 
should  be  shaped  like  shields  , for  that  is  one  of  their 
uses ; they  are  shields  to  protect  the  young  nastur- 
tium seeds  from  the  hot  sun  and  from  the  view  of 
devouring  enemies.  The  nasturtiums  are  natives 
of  Peru  and  Chili,  and  it  is  fitting  that  the  leaves 
should  develop  in  shield-shape,  and  the  shields 
overlap  until  they  form  a tent  to  shade  the  tender 
developing  fruit  from  the  burning  sun.  But  they 
were  never  meant  to  shield  the  flower,  which  thrusts 
its  brilliant  petals  out  between  the  shields,  and  calls 
loudly  to  the  world  to  admire  it.  It  would  indeed 
be  a pity  for  such  a remarkable  flower  to  remain 
hidden ; its  five  sepals  are  united  at  their  base,  and 
the  posterior  one  is  extended  into  a long  spur,  a tube 
with  a delectable  nectar-well  at  its  tip.  The  five 
petals  are  set  around  the  mouth  of  this  tube,  the 
two  upper  ones  differing  in  appearance  and  office 
from  those  below;  these  two  stand  up  like  a pair  of 
fans,  and  on  them  are  lines  which  converge;  on  the 
upper  sepals  are  similar  lines  pointing  toward  the 
same  interesting  spot.  And  what  do  all  these  lines 
lead  to,  except  a veritable  treasure-cave  filled  with 
nectar!  The  lower  petals  tell  another  story;  they 
stand  out,  making  a platform,  or  doorstep,  on  which 
the  visiting  bee  alights.  But  it  requires  a big  insect  to  do  the  work  of  this 
flower,  and  what  if  some  inefficient  little  bee  or  fly  should  alight  on  the 


Cultivated- Plant  Stud) 


621 


petal-doorstep  and  steal  into  the  cave  surreptitiously ! This  contingency 
is  guarded  against  thus : Each  of  these  lower  petals  narrows  to  a mere 

insect  footbridge  at  their  inner  end ; and  in  order  to  render  this  footbridge 
quite  impassable,  it  is  beset  with  irregular  little  spikes  and  projecting 
fringes,  sufficient  to  perplex  or  discourage  any  small  insect  from  crawling 
that  way. 

But  why  all  these  guiding  lines  and  guarded  bridges?  If  you  watch 
the  same  blossom  for  several  successive  days,  it  will  reveal  this  secret. 
When  a flower  first  opens,  the  stamens  are  all  bent  downward,  but  when 
an  anther  is  ready  to  open  its  pollen  doors,  the  filament  lifts  it  up  and 
places  it  like  a sentinel  blocking  the  doorway  to  the  nectar  treasure. 
Then  when  the  robber  comes,  whether  it  be  butterfly,  bee  or  humming- 
bird, it  gets  a round  of  pollen  ammunition  for  its  daring.  Perhaps  there

may  be  two  or  three  anthers  standing  guard  at  the  same  time,  but,  as  soon 
as  their  pollen  is  exhausted,  they  shrivel  and  give  room  for  fresh  anthers. 
Meanwhile,  the  stigma  has  its  three  lobes  closed  and  lying  idly  behind  and 
below  the  anthers;  after  all  the  pollen  is  shed,  the  style  raises  and  takes 
its  position  at  the  cave  entrance  and  opens  up  its  stigmas,  like  a three- 
tined  fork,  to  rake  the  pollen  from  any  visiting  insect,  thus  robbing  the 
robber  of  precious  gold-dust  which  shall  fertilize  the  seeds  in  its  three- 
lobed  ovary.  Although  the  flower  needs  to  flare  its  colors  wide  to  call  the 
bees  and  hummingbirds,  yet  the  growing  seeds  must  be  protected;  there- 
fore, the  stem  which  held  the  flower  up  straight,  now  twists  around  in  a 
spiral  and  draws  the  triplet  seeds  down  behind  the  green  shields. 

Nasturtium  leaves  are  very  pretty,  and  are  often  used  as  subjects  for 
decorative  water-color  drawings.  The  almost  circular  leaf  has  its  stem 
attached  below  and  a little  at  one  side  of  the  center;  the  leaves  are  bril- 
liant green  above  but  quite  pale  beneath,  and  are  silvery  when  placed 
beneath  the  water.  The  succulent  stems  have  a way  of  twisting  half 
around  the  wires  of  the  trellis  and  thus  holding  the  plant  secure  to  its 
support.  But  if  there  is  no  trellis,  the  main  stem  seems  to  awaken  to  the 


622

x'esponsibility  and  grows  quite  stocky,  often  lifting  the  plant  a foot  or  two 
in  height,  and  from  its  summit  sending  out  a fountain  of  leaf  and  flower 
stems. 

The  nasturtium  is  among  the  most  interesting  and  beautiful  of  our 
garden  flowers,  and  will  thrive  in  any  warm,  sunny,  fairly  moist  place. 
Its  combinations  of  color  are  exceedingly  rich  and  brilliant.  H.  H.  says 
of  it : 

“ How  carelessly  it  wears  the  velvet  of  the  same 
Unfathomed  red,  which  ceased  when  Titian  ceased 
To  paint  it  in  the  robes  of  doge  and  priest .” 


LESSON  CLVII 
The  Nasturtium 

Leading  thought — The  nasturtium  has  a special  arrangement  by  which 
it  sends  its  own  pollen  to  other  flowers  and  receives  pollen  from  other 
flowers  by  insect  messengers. 

Method — The  nasturtiums  and  their  foliage  should  be  brought  into  the 
schoolroom  in  sufficient  quantity  so  that  each  child  may  have  a leaf  and  a 
flower  for  study.  The  object  of  the  lesson  is  to  interest  the  pupils  in 
studying,  in  their  gardens,  one  flower  from  the  bud  until  the  petals  wither, 
taking  note  of  what  happens  each  day  and  keeping  a list  of  the  insect 
visitors. 

Observations — i.  Look  at  the  back  of  the  flower.  What  is  there 
peculiar  about  the  sepals?  How  many  sepals  are  there  ? How  many  join 
to  make  the  spur?  What  is  in  this  spur?  Taste  of  the  tip.  Find  where 
the  nectar  is. 

2.  Look  the  flower  in  the  face.  How  do  the  two  upper  petals  differ 
in  shape  from  the  three  lower  ones?  What  markings  are  there  on  the 
upper  petals?  Where  do  these  lines  point ? Are  there  any  markings  on 
the  sepals  pointing  in  the  same  direction?  If  an  insect  visiting  a flower 
should  follow  these  lines,  where  would  it  go? 

3.  Describe  the  shape  of  the  lower  petals.  Suppose  a little  ant  were 
on  one  of  these  petals  and  she  tried  to  pass  over  to  the  nectar-tube  or  spur, 
would  the  fringes  hinder  her? 

4.  Look  down  the  throat  of  the  spur,  and  tell  what  a bee  or  other 
insect  would  have  to  crawl  over  before  it  could  get  at  the  nectar. 

5.  In  your  garden,  or  in  the  bouquet  in  the  window  if  you  cannot  visit 

a garden,  select  a nasturtium  that  is  just  opening  and  watch  it  every  day, 
making  the  following  notes : When  the  blossom  first  opens  where  are  the 

eight  stamens?  Are  the  unripe,  closed  anthers  lifted  so  as  to  be  in  the 
path  of  the  bee  which  is  gathering  nectar?  How  do  the  anthers  open? 
How  is  the  pollen  held  up  in  the  path  to  the  nectar?  Can  you  see  the 
stigma  of  this  flower?  Where  is  it?  Note  the  same  flower  on  successive 
days:  How  many  anthers  are  open  and  shedding  pollen  to-day?  Are 

they  all  in  the  same  position  as  yesterday?  What  happens  to  the  anthers 
which  have  shed  their  pollen  ? 

6.  When  the  stigma  rises  in  the  nectar  path,  how  does  it  look? 
Where  are  all  the  anthers  when  the  stigma  raises  its  three  tines  to  rake  the 
pollen  off  the  visiting  insect  ? Do  you  know  why  it  is  an  advantage  to  the 
nasturtium  to  develop  its  seed  by  the  aid  of  the  pollen  from  another  plant  ? 


Cultivated-Plant  Study 


623 


7.  Can  you  see  the  beginning 
of  the  seed-case  when  the  stigma 
arises  to  receive  the  pollen  ? 

8.  The  flowers  project  beyond 
the  leaves.  Do  the  ripening  seed- 
cases  do  this?  What  happens  to 
their  stems  to  withdraw  them  be- 
hind the  leaf? 

9.  Sketch  a nasturtium  leaf, 
and  explain  why  it  is  like  a shield.  How 
does  the  leaf  look  when  under  water? 

10.  What  sort  of  stem  has  the  nas- 
turtium? How  does  it  manage  to  climb 
the  trellis?  If  it  has  no  trellis  to  climb, 
does  it  lie  flat  upon  the  ground? 


THE  BEE-LARKSPUR 
Teacher's  Story 

This  common  flower  of  our  gardens,  send- 
ing up  from  a mass  of  dark,  deeply-cut  leaves 
tall  racemes  of  purple  or  blue  flowers,  has  a 
very  interesting  story  to  tell  those  who 
watch  it  day  by  day  and  get  acquainted  with 
it  and  its  insects  guests.  The  brilliant  color 
of  the  flowers  is  due  to  the  sepals,  which  are 
purple  or  blue,  in  varying  shades;  but  as  if  to 
show  that  they  are  sepals  instead  of  petals,  each 
has-son  the  back  side  near  its  tip,  a green  thick- 
ened spot.  If  we  glance  up  the  flower  stalk, 
we  can  see  that,  in  the  upper  buds,  the  sepals 
are  green,  but  in  the  lower  buds  they  begin  to 
show  the  blue  color;  and  in  a bud  just  ready 
to  open,  we  can  see  that  the  blue  sepals  are 
each  tipped  with  a green  knob,  and  this  remains 
green  after  the  sepals  expand.  The  upper  and 
rearmost  sepal  is  prolonged  into  a spur,  which 
forms  the  outside  covering  of  the  nectar-spur; 
it  is  greenish  and  wrinkled  like  a long-wristed, 
suede  glove ; two  sepals  spread  wide  at  the  sides 
and  two  more  below.  All  this  expanse  of  blue 
sepals  is  simply  for  a background  for  the  petals, 
which,  by  their  contrasting  color,  show  the  bees 
where  to  probe  for  nectar.  Such  inconsequen- 
tial petals  as  they  are!  Two  of  them  “hold 
hands”  to  make  an  arch  over  the  entrance  to 
the  nectar  tube;  and  just  below  these  on  each 
side  are  two  more  tiny,  fuzzy,  spreading  petals, 
often  notched  at  the  tip  and  always  hinged  in 
a peculiar  way  about  the  upper  petal;  they  stand  guard  at  the  door 
to  the  nectar  storehouse.  If  we  peel  off  the  wrinkled  sepal-covering

Handbook  of  Nature-Study 


of  the  spur,  we  can  see  the  upper  petals  extending  back  into  it,  making 
a somewhat  double-barreled  nectary. 

If  we  look  into  a larkspur  flower  just  opened,  we  see  below  the  petals 
a bunch  of  green  anthers,  hanging  by  white  threadlike  filaments  to  the 
center  of  the  flower  and  looking  like  a bunch  of  lilliputian  bananas. 
Behind  these  anthers  is  an  undeveloped  stigma,  not  visible  as  yet. 
After  the  _ flower  has  been  open  for  a short  time,  three  or  four  of  the 
anthers  rise  up  and  stand  within  the  lower  petals;  while  in  this 
position,  their  white  pollen  bursts  from  them,  and  no  bee  may  then 
thrust  her  tongue  into  the  nectar-spur  without  being  powdered 
with  pollen.  As  soon  as  the  anthers  have  discharged  their  pollen, 
they  shrivel  and  their  places  are  taken  by  fresh  ones.  It  may 
require  two  or  three  days  for  all  the  anthers' to  lift  up  and  get  rid  of 
their  pollen.  After  this  has  been  accomplished,  the  three  white,  closely 
adhering  pistils  lift  up  their  three  stigmas  in  the 
self-same  path  to  the  nectar;  and  now  they  are 
ready  to  receive  the  pollen  which  the  blundering 
bee  brings  from  other  flowers.  Since  we  cannot 
always  study  the  same  flower  for  several  conse- 
cutive days,  we  can  read  the  whole  story  by 
studying  the  flowers  freshly  opened  on  the 
upper  portion  of  the  stalk,  and  those  below  them 
that  are  in  more  advanced  stages. 

The  bees,  especially  the  bumblebee,  will  tell 
the  pollenation  story  to  us  in  the  garden.  The 
contrasting  color  of  the  petals  and  sepals  tells 
her  where  to  alight;  this  she  does  accurately, 
and  the  inconsequential  lower  petals  seem  made 
for  her  to  grasp;  she  presses  them  to  her  breast 
with  her  front  and  middle  legs  with  a dramatic, 
almost  ecstatic,  gesture  that  is  comical  to  wit- 
ness, and  holds  them  firmly  while  she  thrusts 
her  head  into  the  opening  between  them;  she 
probes  the  spur  twice,  evidently  finding  there 
the  two  nectar-wells.  It  is  a fascinating  past- 
time to  follow  her  as  she  goes  from  flower  to 
flower  like  a Madam  Pompadour,  powdered 
with  her  white  pollen.  In  order  that  a bee  may 
work  on  these  flowers,  it  is  necessary  that  they

stem  takes,  the  flowers  will  twist  around  on 
their  pedicels  until  they  face  the  world  and  the  bee,  exactly  as  if  they  were 
on  a normally  erect  stem. 

All  the  larkspurs  have  essentially  the  same  pollen  story , although 
some  have  only  two  petals;  in  every  case  the  anthers  at  first  hang  down, 
and  later  rise  up  in  the  path  to  the  nectar,  in  order  to  discharge  their 
pollen;  after  they  wither,  the  stigmas  arise  in  a similar  position. 

The  bee-larkspur  has  a very  beautiful  fruit.  It  consists  of  three 
graceful  capsules  rising  from  the  same  base  and  flaring  out  into  pointed 
tips.  The  seeds  are  fastened  to  the  curved  side  of  e.ach  capsule,  which.

when  ripe,  opens  so  that  they  may  be  shaken  out  by  the  winds.  When 
studying  the  bud,  we  notice  two  little  bracts  set  at  its  base  and  these 
remain  with  the  fruit. 


LESSON  CLVIII 
The  Bee-larkspur 

Leading  thought — The  bee-larkspur  begins  blossoming  early  in  the 
season,  the  blossom  stalk  elongating  and  developing  new  buds  at  its  tip 
until  late  in  autumn.  The  flower  has  a very  interesting  way  of  making 
the  bees  carry  its  pollen. 

Method — Bring  to  the  schoolroom  a flower  stalk  of  the  bee-larkspur, 
and  there  study  the  structure  and  mechanism  of  the  flower.  This  lesson 
should  inspire  the  puoils  to  observe  for  them- 
selves the  visiting  bees  and  the  maturing  seeds. 

Ask  them  to  write  an  account  of  a bumblebee 
making  morning  calls  on  the  larkspurs 

Observations — 1.  Which  flowers  of  the  lark- 
spur open  first — those  near  the  tip  of  the  stem  or 
those  below? 

2.  Examine  the  buds  toward  the  tip  of  the 
flower  stalk.  What  color  are  the  sepals  in 
these  buds?  Do  the  sepals  change  color  as 
the  flower  opens?  Note  the  little  green  knobs 
which  tip  the  closed  sepals  that  clasp  the  bud. 

What  color  are  the  sepals  on  the  open  flower? 

Is  there  any  green  upon  them  when  open? 

3.  Where  is  the  nectar-spur?  Which  sepal 
forms  this  ? How  are  the  oth  er  sepals.arranged  ? 

4.  Now  that  we  know  the  flower  gets  its 
brilliant  color  from  its  sepals,  let  us  find  the 
petals.  Look  straight  into  the  flower,  and 
note  what  forms  the  contrasting  color  of  the 
heart  of  the  flower;  these  are  the  petals.  Can 
you  see  that  two  are  joined  above  the  open- 
ing into  the  nectar-tube?  How  many  guard  the  entrance  from  below? 
How  are  these  lower  petals  hinged  about  the  upper  one?  Peel  a sepal- 
cover  from  the  nectar-spur,  and  see  if  the  upper  petals  extend  back  within 
the  spur,  forming  nectar-tubes? 

5.  Take  a flower  just  opened,  and  describe  what  you  see  below  the 
petals.  What  is  the  color  of  the  anthers?  Of  the  filaments?  Can  you 
see  the  stigma? 

6.  Take  a flower  farther  down  the  stalk,  which  has  therefore  been 
open  longer,  and  describe  the  position  of  the  anthers  in  this.  Are  there 
any  of  them  standing  upright  ? Are  they  discharging  their  pollen  ? What 
color  is  the  pollen?  Are  these  upright  anthers  in  the  way  of  the  bee, 
when  she  thrusts  her  tongue  into  the  nectar-tube? 

7.  Take  the  oldest  flower  you  can  find.  What  has  happened  to  the 
anthers?  Can  you  see  the  pistils  in  this ? In  what  position  now  are  the 
stigmas  ? 

8.  Push  aside  the  anthers  in  a freshly  opened  flower  and  see  if  you  can 
find  the  stigmas.  What  is  their  position?  How  do  they  change  in  form 


The  larkspur.

and  position  after  the  pollen  is  shed  ? Do  they  arise  in  the  path  of  the 
bee  before  all  the  pollen  from  the  anthers  of  their  own  flower  is  shed?  If 
so,  how  are  they  pollenated? 

9-  Suggestions  for  Observation  in  the  Garden — Watch  a bumblebee 
working  on  the  larkspur  and  answer  the  following  questions:  How  does 

she  hold  on  to  the  flower?  Where  does  she  thrust  her  tongue?  Can  she 
get  the  nectar  without  brushing  the  pollen  from  the  anthers  which  are 
lifting  up  at  the  opening  of  the  nectar-tube?  In  probing  the  older  flow- 
ers, how  would  she  come  in  contact  with  the  lifted  stigmas?  How  do  the 
petals  contrast  in  color  with  the  sepals?  Does  this  tell  the  bees  where  to 
look  for  nectar?  Compare  the  common  larkspur  with  the  bee-larkspur, 
and  notice  the  likeness  and  difference.  What  kind  of  fruit  capsules  has 
the  bee-larkspur?  Describe  the  seeds,  and  how  they  are  scattered. 

THE  BLUE  FLAG,  OR  IRIS 
Teacher's  Story 

Beautiful  lily,  dwelling  by  still  rivers 
Or  solitary  mere, 

Or  where  the  sluggish  meadow  brook  delivers 
Its  waters  to  the  weir! 

The  burnished  dragon  fly  is  thine  attendant, 

And  tilts  against  the  field, 

And  down  the  listed  sunbeams  rides  resplendent 
With  steel-blue  mail  and  shield. 

— From  “Flower-de-luce,'’  Henry  W.  Longfellow. 

The  iris  blossom  has  a strange  appearance,  and  this  is  because  nothing 
in  it  is  as  it  seems.  The  style  of  the  pistil  is  divided  into  three  broad 
branches  and  they  look  like  petals;  and  they  have  formed  a conspiracy 
with  the  sepals  to  make  a tunnel  for  bees,  leaving  the  petals  out  of  the 
plan  entirely  and  the  sepals  “rise  to  the  occasion.”  The  petals  stand  up 
lonely  between  the  three  strangely  matched  pairs,  and  all  they  accomplish 
by  their  purple  guiding  lines,  is  to  basely  deceive  the  butterflies  and  other 
insects  which  are  in  the  habit  of  looking  for  nectar  at  the  center  of  a 
flower.  If  we  look  directly  down  into  the  flower  of  the  blue  flag,  there  are 
ridges  on  the  broad  styles  and  purple  veins  on  the  petals,  all  pointing 
plainly  to  the  center  of  the  flower,  and  any  insect  alighting  there  would 
naturally  seek  for  nectar-wells  where  all  these  lines  so  plainly  lead.  But 
there  is  an  “April  fool”  for  the  insects  which  trust  to  these  guides,  for  there 
is  no  nectar  to  be  had  there.  Dr.  Needham,  in  his  admirable  study  of  this 
flower  and  its  visitors  (American  Naturalist,  May,  1900),  tells  us  that  he 
has  seen  the  little  butterflies  called  “skippers,”  the  flag  weevils  and  the 
flower  beetles  all  made  victims  of  this  deceptive  appearance ; this  is  evi- 
dence that  the  nectar  guiding  lines  on  flowers  are  noted  and  followed  by 
insects. 

The  blue  flag  is  made  for  bees;  the  butterflies  and  beetles  are  inter- 
lopers and  thieves  at  best.  The  bees  are  never  deceived  into  seeking  the 
nectar  in  the  wrong  place.  They  know  to  a certainty  that  the  sepal  with

its  purple  and  yellow  tip  and  many  guiding  lines  although  far  from  the 
center  of  the  flower,  is  the  sure  path  to  the  nectar.  A bee  alights  on  the 
lip  of  the  sepal,  presses  forward  scraping  her  back  against  the  down- 
hanging stigma,  then  scrapes  along  the  open  anther  which  lies  along  the 
roof  of  the  tunnel;  and  she  here  finds  a pair  of  guiding  lines  each  leading 
to  a nectar-well  at  the  very  base  of  the  sepal.  The  bees  which  Dr.  Need- 
ham found  doing  the  greatest  work  as  pollen-carriers  were  small  solitary 
bees  ( Clisodon  terminalis  and  Osmia  destructa) ; each  of  these  alighted 
with  precision  on  the  threshhold  of  the  side  door,  pushed  its  way  in,  got 
the  nectar  from  both  wells,  came  out  and  sought  another  side  door 
speedily.  One  might  ask  why  the  bee  in  coming  out  did  not  deposit  the 
pollen  from  its  own  anther  upon  the  stigma ; but  the  stigma  avoids  this 
by  hanging  down,  like  a flap  to  a tent,  above  the  entrance,  and  its  sur- 
face for  receiving  pollen  is  directed  so  that  it  gathers  pollen  from  the 
entering  bee  and  turns  its  back  to  the  bee  that  is  just  making  its  exit. 

The  arrangement  of  the  flower  parts  of  the  iris  may  be  described 
briefly  thus:  three  petals,  three  sepals,  a style  with  three  branches ; the 
latter  being  broad  and  flat  and  covering  the  bases  of  the  three  sepals, 
making  tubes  which  lead  to  the  nectar;  three  anthers  lie  along  the 
under  side  of  the  styles.  The  wild  yellow  iris  is  especially  fitted  for 
welcoming  the  bumblebee  as  a pollen-carrier,  since  the  door  between 
the  style  and  the  sepal  is  large  enough  to  admit  this  larger  insect. 
The  bumblebees  and  the  honey-bees  work  in  the  different  varieties 
of  iris  in  gardens.

In  some  varieties  of  iris 
there  is  a plush  rug  belong  the 
vestibule  floor  over  which  the 
bee  passes  to  get  the  nectar. 
Through  a lens,  this  plush  is 
exquisite — the  nap  of  white 
filaments  standing  up  and  tip- 
ped with  brilliant  yellow.  Vari- 
ous theories  as  to  the  use  of  this 
plush  have  been  advanced,  the 
most  plausible  being  that  it  is 
to  keep  the  ants  out ; but  the 
ant  could  easily  pass  along 
either  side  of  it.  While  holding 
an  iris  in  my  hand,  one  day  in 
the  garden,  a bumblebee  visited 
it  eagerly,  never  noting  me; 
after  she  had  probed  the  nectar- 
wells,  she  probed  or  nibbled 
among  the  plush,  working  it 
thoroughly  on  her  way  out. 
Was  she  a foolish  bee,  or  did 
she  find  something  there  to 
eat?  What  child  will  find  if 
other  bees  do  this? 

LESSON  CLIX 
The  Blue  Flag  or  Iris 

Leading  thought — Each  iris  flower  has  three  side  doors  leading  to  the 
nectar-wells;  and  the  bees,  in  order  to  get  the  nectar,  must  brush  off  the 
pollen  dust  on  their  backs. 

Method — While  the  blue  flag  is  the  most  interesting  of  our  wild  species 
of  iris,  yet  the  flower-de-luce,  or  the  garden  iris,  is  quite  as  valuable  for 
this  lesson.  The  form  of  the  flowers  may  be  studied  in  the  schoolroom, 
but  the  pupils  should  watch  the  visiting  insects  in  the  garden  or  field. 

Observations — i.  Look  for  the  side  doors  of  the  iris  blossom.  Which 
part  of  the  flower  forms  the  doorstep?  How  is  it  marked  to  show  the 
way  in?  Which  part  of  the  flower  makes  the  arch  above  the  door? 

2.  Find  the  anther,  and  describe  how  it  is  placed.  Gan  you  see  two 
nectar-wells?  Explain  how  a bee  will  become  dusted  with  pollen  while 
getting  the  nectar. 

3 . Where  is  the  stigma  ? What  is  there  very  peculiar  about  the  styles 
of  the  iris?  Can  a bee,  when  backing  out  from  the  side  door,  dust  the 
Stigma  with  the  pollen  she  has  just  swept  off?  Why  not?  How  does  the 
stigma  of  the  next  flower  that  the  bee  visits  get  some  of  the  pollen  from 
her  back  ? 

4.  Look  straight  down  into  an  iris  flower.  Can  you  see  the  three 
petals?  How  are  they  marked?  How  would  these  lines  on  the  petals 
mislead  any  insect  that  was  searching  for  nectar? 

5.  Watch  the  insects  visiting  the  iris.  Do  you  know  what  they  are? 
What  do  they  do?

THE  SUNFLOWER 
Teacher's  Story 

Many  of  the  most  beautiful  of  the  autumn  flowers  belong  to  the 
Compositae , a family  of  such  complicated  flower  arrangement  that  it  is 
very  difficult  for  the  child  or  the  beginner  in  botany  to  comprehend  it; 
and  yet,  when  once  understood,  the  composite  scheme  is  very  simple  and 
beautiful,  and  is  repeated  over  and  over  in  flowers  of  very  different 
appearance.  It  is  a plan  of  flower  cooperation;  there  are  many  flowers 
associated  to  form  a single  flower-head.  Some  of  these,  the  “ray,”  or 
“banner,”  flowers,  hold  out  bright  pennants  to  attract  the  attention  of 
insects;  while  the  disk-flowers,  which  they  surround,  attend  to  the  matter 
of  the  pollenation  and  production  of  seed. 

The  large  garden  sunflower  is  the  teacher’s  ally  to  illustrate  to  the 
children  the  story  of  the  composites.  Its  florets  are  so  large  that  it  is  like 
a great  wax  model.  And  what  could  be  more  interesting  than  to  watch 
its  beautiful  inflorescence — that  orderly  march  toward  the  center  in 
double  lines  of  anther  columns,  with  phalanxes  bearing  the  stigmas  sur- 
rounding them;  and  outside  all,  the  ranks  of  ray-flowers  flaunting  their 
flags  to  herald  to  the  world  this  peaceful  conquest  of  the  sleeping,  tented 
buds  at  the  center? 

Ordinarily,  in  nature-study  we  do  not  pull  the  flowers  apart,  as  is 
necessary  in  botany;  in  nature-study,  all  that  we  care  to  know  of  the 
flower  is  what  it  does,  and  we  can  see  that  without  dissection.  But  with 
the  composite  the  situation  is  quite  different.  Here  we  have  an  assem- 
blage of  flowers,  each  individual  doing  its  own  work  for  the  community; 
and  in  order  to  make  the  pupils  understand  this  fact  it  is  necessary  to 
study  the  individual  florets. 

We  begin  with  the  study  of  one  of  the  buds  at  the  center  of  the  flower- 
head;  this  shows  the  white,  immature  seed  below,  and  the  closed,  yellow 
corolla-tube  above.  Within  the  corolla  may  be  seen  the  brown  anther- 
tube,  and  on  the  upper  part  of  the  seed  are  two  little,  white,  earlike 
scales,  to  which  especial  notice  should  be  directed,  since  in  other  compo- 
sites there  are  many  of  these  scales  and  they  form  the  pappus — the  bal- 
loon to  carry  the  seed.  The  bud  shows  best  the  protecting  chaffy  scale 
which  enfolds  the  seed,  its  pointed,  spine-edged  tip  being  folded  over  the 
young  bud,  as  may  be  seen  by  examining  carefully  the  center  of  a freshly 
opened  sunflower.  In  this  tubular  bud  (see  Fig.  p.  632),  there  is  a tele- 
scopic arrangement  of  the  organs,  and  one  after  another  is  pushed  out. 
First,  the  corolla-tube  opens,  starlike,  with  five  pointed  lobes,  very  pretty 
and  graceful,  with  a bulblike  base;  from  this  corolla  pushes  out  the  dark- 
brown  tube,  made  up  of  five  anthers  grown  together.  By  opening  the 
corolla,  we  see  the  filaments  of  the  stamens  below  the  joined  anthers. 
This  anther  tube,  if  examined  through  a lens,  shows  rows  of  tiny  points 
above  and  below,  two  to  each  anther,  as  if  they  had  been  opened  like  a 
book  to  join  edges  with  their  neighbors.  The  anther-tube  is  closed  at  the 
tip,  making  a five-sided  cone;'  and  at  the  seams,  the  yellow  pollen  bulges 
out,  in  starlike  rays.  The  pollen  bulges  out  for  good  reason,  for  behind  it 
is  the  stigma,  like  a ramrod,  pushing  all  before  it  in  the  tube  for  it  is  its 
turn  next  to  greet  the  outer  world.  The  two  stigma-lobes  are  pressed 
together  like  the  halves  of  a.sharpened  pencil,  and  they  protrude  through 
the  anther-tube  as  soon  as  all  the  pollen  is  safely  pushed  out ; then  the

stigma-lobes  separate,  each  curling  backwards  so  as  to  offer  a receptive 
surface  to  welcome  pollen  grains  from  other  florets,  or  even  other  sun- 
flowers. In  the  process  of  curling  back,  they  press  the  anther-tube  down 
into  the  corolla,  and  thus  make  the  floret  shorter  than  when  in  the  pollen 
stage.  The  banner-flower  differs  in  many  essentials  from  the  perfect 
florets  of  the  disk.  If  we  remove  one  from  the  flower-head,  we  find  at  its 
base  a seedlike  portion,  which  is  a mere  pretense;  it  is  shrunken,  and 
never  can  be  a seed  because  it  has  connected  with  it  no  stigma  to  bring  to 
it  the  pollen.  Nor  does  this  flower  have  stamens  nor  a tubular  corolla; 
instead  it  has  one  great,  petallike  banner,  many  times  longer  and  wider 
than  the  corollas  of  the  other  flowers.  All  this  flower  has  to  do  is  to  hold 
its  banner  aloft  as  a sign  to  the  world,  especially  the  insect  world,  that 
here  is  to  be  found  pollen  in  plenty,  and  nectar  for  the  probing. 

But  more  wonderful  than  the  perfection  of  each  floret  is  their  arrange- 
ment in  the  flower-head.  Around  the  edge  of  the  disk  the  banner-flowers, 
in  double  or  treble  rank,  flare  wide  their  long  petals  like  the  rays  of  the 
sun,  making  the  sunflower  a most  striking  object  in  the  landscape.  If 
the  sunflower  has  been  open  for  several  days,  next  to  the  ray-flowers  will 
be  seen  a circle  of  star-mouthed  corollas  from  which  both  ripened  pollen 
and  stigmas  have  disappeared,  and  the  fertilized  seeds  below  them  are 
attaining  their  growth.  Next  comes  a two  or  three-ranked  circle,  where 
the  split,  coiled-back  stigma-lobes  protrude  from  the  anther-tubes ; within 
this  circle  may  be  two  or  three  rows  of  florets,  where  pollen  is  being  pushed 
out  in  starry  radiance ; and  within  this  ring  there  may  be  a circle  where 
the  anther-tubes  are  still  closed ; while  at  the  center  lie  the  buds,  arranged 
in  exquisite  pattern  of  circling  radii,  cut  by  radii  circling  in  the  opposite 
direction;  and  at  the  very  center  the  buds  are  covered  with  the  green 
spear-points  of  their  bracts.  I never  look  at  the  buds  in  the  sunflower 
without  wondering  if  the  study  of  their  arrangement  is  not  the  basis  of 
much  of  the  most  exquisite  decoration  in  Moorish  architecture.  To

appreciate  fully  this  procession  of  the  bloom  of  the  sunflower  from  its  rim 
to  its  center,  we  need  to  watch  it  day  by  day — then  only  can  its  beauty 
become  a part  of  us. 

The  great,  green  bracts,  with  their  long  pointed  tips,  which  “shingle” 
the  house  of  every  sunflower  family,  should  be  noted  with  care,  because 
these  bracts  have  manifold  forms  in  the  great  Compositae  family ; and  the 
pupil  should  learn  to  recognize  this  part  of  the  flower-head,  merely  from 
its  position.  In  the  burdocks,  these  bracts  form  the  hooks  which  fasten 
to  the  passer-by;  in  the  thistle,  they  form  the  prickly  vase  about  the 
blossom;  while  in  the  pearly  everlasting,  they  make  the  beautiful,  white, 
shell-like  mass  of  the  flower  which  we  treasure  as  immortal.  In  the  sun- 
flower, these  bracts  are  very  ornamental,  being  feltlike  outside  and  very 
smooth  inside,  bordered  with  fringes  of  pretty  hairs,  which  may  be  seen 
best  through  a lens.  They  overlap  each  other  regularly  in  circular  rows, 
and  each  bract  is  bent  so  as  to  fit  around  the  disk. 

In  looking  at  a mass  of  garden  sunflowers,  we  are  convinced  that  the 
heavy  heads  bend  the  stems,  and  this  is  probably  true,  in  a measure. 
But  the  stems  are  very  solid  and  firm,  and  the  bend  is  as  stiff  as  the  elbow 
of  a stovepipe;  and  after  examining  it,  we  are  sure  that  this  bend  is  made 
with  the  connivance  of  the  stem,  rather  than  despite  it.  Probably  most 
people,  the  world  over,  believe  that  sunflowers  twist  their  stems  so  that 
their  blossoms  face  the  sun  all  day.  This  belief  shows  the  utter  content- 
ment of  most  people  with  a pretty  theory.  If  you  believe  it,  you  had  best 
ask  the  first  sunflower  you  see  if  it  is  true,  and  she  will  answer  you  if  you 
will  ask  the  question  morning,  noon  and  night.  My  own  observations 
make  me  believe  that  the  sunflower,  during  the  later  weeks  of  its  bloom,  is 
like  the  Mohammedan,  keeping  its  face  toward  the  east.  True,  I have 
found  many  exceptions  to  this  rule,  although  I have  seen  whole  fields  of 
sunflowers  facing  eastward,  when  the  setting  sun  was  gilding  the  backs  of 
their  great  heads.  If  they  do  turn  with  the  sun,  it  must  be  in  the  period 
of  earliest  blossoming  before  they  become  heavy  with  ripening  seeds. 

The  sunflower  seed  is  eagerly  sought  by  many  birds,  and  it  is  raised 
extensively  for  chicken-feed.  The  inadequate  little  pappus  falls  off,  and 
the  seeds  are  set,  large  end  up,  in  the  very  ornamental  diamond-shaped 
sockets.  They  finally  become  loosened,  and  now  we  see  a reason  for  the 
bending  flower-head ; for,  as  the  great  stem  is  assaulted  by  the  winds  of 
autumn,  the  bended  heads  shake  out  their  seed  and  scatter  them  far 
afield. 

LESSON  CLX 
The  Sunflower 

Leading  thought — The  sunflower  is  not  a single  flower,  but  is  a large 
family  of  flowers  living  together ; and  each  little  flower,  or  floret,  as  it  is 
called,  has  its  own  work  to  do  for  the  family  welfare. 

Method — Early  in  September,  when  school  first  opens,  is  the  time  for 
this  lesson.  If  sunflowers  are  growing  near  by,  they  should  be  studied 
where  they  stand;  and  their  story  may  thus  be  more  completely  told. 
Otherwise,  a sunflower  should  be  brought  to  the  schoolroom  and  placed  in 
water.  If  one  is  selected  which  has  just  begun  to  blossom,  it  will  show, 
day  by  day,  the  advance  of  the  blossoming  ranks.  I have  kept  such  a 
flower  fourteen  days,  and  it  blossomed  cheerfully  from  its  rim  to  its  very

center  A large  sunflower  that  has  only  partially  blossomed  is  also 
needed  for  taking  apart  to  show  the  arrangement  of  this  big  flower-family. 
Take  a bud  from  the  center,  a floret  showing  anther-tube  and  another 
showing  the  curled  pair  of  stigmas,  and  a ray  or  banner-flower.  (See 
Fig. p.  632).  Each  pupil  should  be  furnished  with  these  four  florets;  and 
after  they  have  studied  them,  show  them  the  other  half  of  the  sunflower, 
with  each  floret  in  place.  After  this  preliminary  study,  let  them  observe 
the  blossoming  sunflower  for  several  consecutive  da^s. 

Observations — 1 . A little  flower  which  is  part  of  a big  flower-family  is 
called  a floret.  You  have  before  you  three  florets  of  a sunflower  and  a 
banner-flower.  Study  first  the  bud.  Of  how  many  parts  is  it  composed  ? 
What  will  the  lower,  white  part  develop  into?  Can  you  see  two  little 
white  points  stan  ding  up  from  it  on  each  side  of  the  bud  ? Note  the  shape 
and  color  of  the  unopened  floret.  Note  that  there  is  a narrow,  stiff,  leaf- 
like bract,  which  at  its  base  clasps  the  young  seed,  while  its  pointed  tip 
bends  protectingly  over  the  top  of  the  bud. 

2 . Take  an  open  floret  with  the  long,  dark  brown  tube  projecting  from 
it.  Note  that  the  young  seed  is  somewhat  larger  than  in  the  bud,  and 
that  it  still  has  its  earlike  projections  at  the  top.  Describe  the  shape  of 
the  open  corolla.  Look  at  the  brown  tube  with  a lens.  How  many  sides 
has  it  ? How  many  little  points  projecting  at  the  top  and  bottom  on  each 
side  of  the  tube?  How  does  the  tube  look  at  the  tip,  through  a lens? 
Can  you  see  the  pollen  bursting  out?  Tf  so,  how  does  it  look?  Do  you 
think  that  there  is  just  one  tubular  anther,  or  do  you  think  several 
anthers  are  joined  together  to  make  this  tube?  Open  the  corolla-tube 
carefully,  and  see  if  you  can  answer  this  last  Question.  Open  the  anther- 
tube,  and  see  if  you  can  find  the  pistil  with  its  stigmas. 

3.  Take  a floret  with  the  two  yellow  horns  of  the  stigma  projecting. 
Where  is  the  brown  anther-tube  now?  Is  it  as  long  as  in  the  floret  you 
have  just  studied ? What  has  happened  to  it  ? What  did  the  stigmas  do 
to  the  pollen  in  the  anther-tube  ? How  do  the  two  parts  or  lobes  of  the 
stigma  look  when  they  first  project?  How  later? 

4.  Make  a banner-flower.  How  many  parts  are  there  to  it?  How 
does  the  seedlike  portion  of  the  blossom  look?  Do  you  think  it  will  ever 
be  a good  seed?  Describe  the  corolla  of  this  flower.  How  much  larger  is 
it  than  the  corolla  of  the  florets?  Has  the  banner-flower  any  pistil  or 
stamens?  Of  what  use  is  the  banner-flower  to  the  sunflower  family?  Do 
you  think  that  we  would  plane  sunflowers  in  our  gardens  for  their  beauty 
if  they  had  no  banner-flowers  ? 

5.  After  studying  the  separate  flowers,  study  a sunflower  in  blossom, 
and  note  the  following*  Where  are  the  banner-flowers  placed?  How 
many  rows  are  there  ? How  are  they  set  so  that  their  banners  make  the 
sunflower  look  like  the  sun?  Do  you  see  why  the  central  portion  of  the 
sunflower  is  called  the  disk,  and  the  banner-flowers  are  called  the  rays — 
in  imitation  of  the  sun  ? 

6.  Next  to  the  banner-flowers,  what  sort  of  florets  appear?  How 
many  rows  are  there  ? What  kind  form  the  next  circle,  and  in  how  many 
rows?  What  stages  of  the  florets  do  you  find  forming  the  inner  circle, 
and  how  many  rows  ? What  do  you  find  at  the  center  of  the  flower-head  i 
Note  the  beautiful  pattern  in  which  the  buds  are  arranged.  Can  you  see 
the  separate  buds  at  the  very  center  of  the  sunflower?  If  not,  why?

7.  Make  notes  on  a,  sunflower  that  has  just  opened,  describing  the 
stages  of  the  florets  that  are  in  blossom;  continue  these  notes  every  day 
for  a week,  describing,  each  day,  what  has  happened.  If  the  sunflower 
you  are  observing  is  in  garden  or  field,  note  how  many  days  elapse  between 
the  opening  of  the  outer  row  of  flowers  and  the  opening  of  the  central 
buds. 


8.  Look  below  or  behind  the  sunflower,  and  note  the  way  it  is  at- 
tached to  the  stem.  What  covers  the  disk?  These  green,  overlapping, 
leaflike  structures  are  called  bracts.  What  is  the  shape  of  one  of  these 
bracts  ? What  is  its  texture,  outside  and  inside  ? Look  at  it,  with  a lens.; 
along  the  edges,  and  note  what  you  see.  How  are  the  bracts  arranged? 
Do  they  not  “shingle”  the  house  in  which  the  sunflower-family  lives? 
This  covering  of  the  disk,  or  the  house  where  the  sunflower-family  lives,  is 
called  the  involucre. 

9.  Does  the  stem  of  the  sunflower  hold  it  upright?  Some  people 
declare  that  it  twists  its  stem  so  as  to  face  the  sun  all  day.  Do  you  think 
this  is  true  ? 

10.  Study  a sunflower-head  after  the  seeds  are  ripe.  Do  the  little 
ears  which  you  saw  at  the  top  of  the  seeds  still  remain?  How  does  the 
sunflower  scatter  the  seeds?  Note  how  the  disk  looks  after  the  seeds  are 
all  gone.  What  birds  are  especially  fond  of  sunflower  seeds?  Of  what 
use  are  the  seeds  commercially? 


“ Flowers  have  an  expression  of  countenance  as  much  as  men  or  animals.  Some 
seem  to  smile;  some  have  a sad  expression;  some  are  pensive  and  diffident;  others 
again  are  plain,  honest,  and  upright,  like  the  broad-faced  Sunflower,  and  the  hollyhock .' 

— Henry  Ward  Beecher. 


“ Eagle  of  flowers!  1 see  thee  stand, 

And  on  the  sun's  noon-glory  gaze; 

With  eye  like  his  thy  lids  expand 
A nd  fringe  their  disk  with  golden  rays; 

Though  fixed  on  earth,  in  darkness  rooted  there, 

Light  is  thy  element,  thy  dwelling  air, 

Thy  prospect  heaven."

THE  BACHELOR’S  BUTTON 
Teacher's  Story 

This  beautiful  garden  flower  gives 
a variation  in  form  from  other  com- 
posites when  studied  according  to 
Lesson  CXXXV.  This  valued  garden 
flower  came  to  us  from  Europe  and  it 
sometimes  escapes  cultivation  and 
runs  wild  in  a gentle  way.  We  call 
it  bachelor’s  button;  but  in  Europe 
it  is  called  the  cornflower,  and  under 
this  name  it  found  its  way  into  litera- 
ture. None  of  the  flowers  that  live 
in  families  repays  close  study  better 
than  does  the  bachelor’s  button. 
The  ray-flowers  are  tubular  but  they 
do  not  have  banners.  Their  tubes 
flare  open  like  trumpets,  and  they  are 
indeed  color  trumpets  heralding  to 
the  insect  world  that  there  is  nectar 
for  the  probing  and  pollen  for  ex- 
change. Looked  at  from  above,  the 
ray-flowers  do  not  seem  tubular; 
from  the  sides,  they  show  as  uneven- 
mouthed trumpets  with  lobed  edges; 
but  though  we  search  each  trumpet 
to  its  slender  depths  we  can  find  no 
pistils.  These  ray-flowers  have  no 
duty  in  the  way  of  maturing  seeds. 
In  some  varieties  the  ray-flowers  are 
white,  and  in  others  they  are  blue 
and  purple.  They  vary  in  number 
from  7 to  1 4,  or  more. 

The  disk-flowers  have  a long 
corolla-tube,  which  is  white  and 
delicately  lobed  and  is  enlarged 
toward  the  upper  end  to  a purple 
bulb  with  five,  long,  slender  lobes. 
The  anther-tube  is  purplish  black, 
and  is  bent  into  almost  a hook,  the 
tip  opening  toward  the  middle 
of  the  flower-head.  The 
pollen  is  glistening  white  tinged  with  yellow,  and 
looks  very  pretty  as  it  bursts  out  from  the  dark  tubes. 

The  purple  stigma  first  appears  with  its  tips  close  to- 
gether, but  with  a pollen  brush  just  below  it ; later  it  opens 
into  a short  Y.  The  buds  at  the  center  of  the  flower  are 
bent  hook-shaped  over  the  center  of  the  flower-head.  The  °Pen 

involucral  bracts  or  “shingles”  are  very  pretty,  each  one 
ornamented  with  a scaly  fringe;  they  form  a long,  elegantly  below.  En • 
shaped  base  to  the  flower-head.  After  the  flowers  have  gone  larged.

shape  of  the  ray- flowers.

and  the  seeds  have  ripened,  these  bracts  flare  open,  making  a wide- 
mouthed urn  from  which  the  ripened  seeds  are  shaken  by  the  winds;  and 
after  the  seeds  are  gone, 
the  white  fuzz  of  their 
empty  cases  remains  at 
the  bottom  of  the  urn. 

The  seed  is  plump  and 
shining,  with  a short 
fringe  of  pappus  around 
the  top  and  a contracted 
place  at  one  side  near 
the  base  where  it  grew 
fast  to  the  receptacle; 
for  these  seeds  are  not  set 
on  end,  as  are  those  of 
the  sunflower.  The  short 
pappus  is  hardly  suffici- 
ent to  buoy  up  the  seed, 
and  yet  undoubtedly 
aids  it  to  make  a flying 
jump  with  the  passing 
breeze.

THE  SALVIA,  OR 
SCARLET  SAGE 
Teacher's  Story 
The  flower  story  of 
the  sage  is  so  peculiar 
that  Darwin  has  used  it 
to  illustrate  the  mechan- 
isms present  in  some 
flowers  which  the  visit- 
ing insects  must  work  in 
order  to  get  the  nectar. 

The  scarlet  sage,  which 
gladdens  our  flower  beds 
during  the  summer  and 
autumn  with  its  bril-  The  salvia , or  scarlet  sage,  showing  the  bracts  still 

liance,  has  as  interesting  present  above  and  falling  as  the  flowers  open. 


638 


Handbook  of  Nature-Study 


a story  as  has  any  of  its  family.  Looking  at  it  from  the  outside,  we 
should  say  that  its  nectar-wells  lie  too  deep  to  be  reached  by  any  insect 
except  a moth  or  butterfly,  or  a humming  bird;  there  is  no  platform  for 
a bee  to  alight  upon,  and  the  tube  is  too  long  to  be  fathomed  by  a bee’s 
tongue;  but  the  bees  are  very  good  business  folk;  they  adapt  themselves 
to  flowers  that  are  not  adapted  to  them,  and  in  autumn  the  glow  of  the 
salvia  attracts  the  eye  scarcely  more  than  the  hum  of  the  visiting  bees 
attracts  the  ear. 

The  calyx  of  the  salvia  is  as  red  as  the  corolla,  and  is  somewhat  fuzzy 
while  the  corolla  is  smooth.  The  calyx  is  a three-lobed  bulging  tube 
held  stiff  by  rather  strong  veins;  there  is  one  large  lobe  above  and  two 
small  ones  below  the  corolla.  The  corolla  is  a tube  which  is  more  than 
twice  the  length  of  the  calyx;  it  is  prolonged  above  into  a projecting 
hood,  which  holds  the  anthers  and  the  stigma;  it  has  a short,  cuplike 
lower  lip  and  two  little  turned-back,  earlike  lobes  at  the  side. 

The  special  mechanism  of  the  salvia  is  shown  in  the  stamens;  there  are 
two  of  these  lying  flat  along  the  floor  of  the  corolla-tube  and  grown  fast  to 
it.  Near  the  mouth  of  the  tube,  each  of  these  lifts  up  at  a broad  angle  to 
the  roof,  and  is  more  or  less  T-shaped,  at  the  tip  of  one  of  the  arms  of  the 
T is  an  anther  while  the  other  arm  is  longer  and  slants  down  and  inward  to 
the  floor  of  the  tube,  as  shown  at  2 in  the  figure. 

The  bee  visiting  the  flower  and  entering  the  corolla-tube,  pushes  her 
head  against  the  inner  arms  of  the  stamens,  lifting  them,  and  in  so  doing 
causes  the  anthers  on  the  front  arms  of  the  T to  lower  and  leave  streaks  of 
pollen  along  her  fuzzy  sides.  The  stigma  is  at  first  concealed  in  the  hood ; 

but,  when  ripe,  it  pro- 
jects and  hangs  down  in 
front  of  the  opening  of 
the  corolla-tube,  whe. 
it  may  be  brushed  along 
one  side  or  the  other  by 
the  visiting  insect,  which 
has  been  dusted  with 
the  pollen  of  some  other 
flower.  The  stigma- 
lobes  open  in  such  a 
manner  that  they  do  not 
catch  the  pollen  from 
the  insect  backing  out  of 
their  own  corolla.  As  the 
nectar  is  at  the  base  of 
the  corolla-tube,  the 
bees,  in  order  to  get  it, 
crawl  in  almost  out  of 
sight.  Late  in  the  sea- 
son they  seem  to  “go 
as  she  crazy”  when  gathering 
this  nectar;  I have  often 
seen  them  searching  the 
bases  of  the  corolla-tubes  which  have  fallen  to  the  ground,  in  order  to  ge* 
vhat  is  left  of  the  sweet  treasure.

But  the  pollen  story  is  not  all  that  is  of  interest  in  the  salvia.  Some  of 
the  parts  of  the  flower  which  are  green  in  most  blossoms,  are  scarlet  as  a 
cardinal’s  robe  in  this.  If  we  glance  at  a flower  stalk,  we  see  that  at  its 
tip  it  looks  like  a braided,  flattened  cone;  this  appearance  is  caused  by 
the  scarlet,  long-pointed  bracts,  each  of  which  covers,  with  its  bulging 
base,  the  scarlet  calyx  which  in  turn  enfolds  the  scarlet  flower  bud. 
These  bracts  fall  as  the  flowers  are  ready  to  open,  making  a brilliant 
carpet  about  the  plant.  Each  flower  stem  continues  to  develop  buds  at 
its  tip  for  a long  season;  and  this,  taken  together  with  its  scarlet  bracts 
and  flowers,  renders  the  salvia  a thing  of  beauty  in  our  gardens,  and 
makes  it  cry  aloud  to  pollen-carriers  that  here,  even  in  late  autumn,  there 
is  plenty  of  nectar. 

LESSON  CLXII 
Salvia,  or  Scarlet  Sage 

Leading  thought — This  flower  has  the  bracts  and  calyx:  scarlet  instead 
of  green,  and  this  makes  it  a brilliant  mass  of  color  to  please  our  eyes  and 
attract  the  pollen-carrying  insects.  Its  anthers  are  arranged  at  the  tip  of 
two  levers,  which  the  insects  push  up  and  down  as  they  enter  the  flower, 
thus  becoming  dusted  with  pollen. 

Method — The  structure  of  this  flower  may  be  studied  in  the  schoolroom 
and  its  mechanism  there  understood;  but  the  most  important  part  of  the 
lesson  is  the  observation  out-of-doors  upon  the  way  the  bees  work  the 
stamen  levers  when  seeking  the  nectar.  This  is  best  observed  during  late 
September  or  October,  after  other  flowers  are  mostly  gone,  and  when  the 
bees  are  working  with  frantic  haste  to  get  all  the  honey  possible. 

Observations — 1.  How  does  the  calyx  of  the  salvia  differ  from  that  of 
other  flowers  in  color?  How  does  it  differ  from  the  corolla  in  texture? 
How  many  lobes  has  it?  How  are  they  placed  about  the  corolla? 

2.  What  is  the  shape  of  the  corolla?  How  does  it  make  a hood  over 
the  entrance  to  the  tube?  What  does  the  hood  hold  ? Is  there  any  plat- 
form made  by  the  lower  lip  of  the  corolla  for  a visiting  insect  to  alight 
upon  ? 

3.  Cut  open  one  side  of  the  corolla  and  describe  how  the  stamens  are 
arranged.  Thrust  your  pencil  into  an  uninjured  flower  and  see  if  the 
anthers  in  the  hood  are  moved  by  it.  How?  Describe  how  a bee  in 
visiting  this  flower  moves  the  anthers  so  as  to  become  dusted  with  pollen. 

4.  Where  is  the  stigma?  How  does  it  receive  pollen  from  visiting 
insects?  Would  it  be  likely  to  get  the  pollen  which  has  just  been  scraped 
off  from  its  own  anthers  by  the  bee  ? Why  ? 

5.  Experiment  to  find  where  the  nectar  is.  Do  you  ever  see  bees 
getting  the  nectar  from  fallen  flowers?  Do  they  get  it  from  the  “front” 
or  the  “back  door?” 

6.  What  other  parts  of  this  flower  are  red,  which  in  other  flowers  are 
green?  How  does  this  make  the  budding  portions  of  the  flower  stem 
look?  Why  does  this  make  the  salvia  a more  beautiful  plant  for  our 
gardens? 

7.  Compare  the  mechanism  of  the  stamens  of  the  scarlet  sage  with 
the  mechanism,  of  the  stamens  of  the  common  garden  sage.

PETUNIAS 


Teacher's  Story 

HESE  red-purple  and  white  flowers,  which, 
massed  in  borders  and  beds,  make  gay  our  gar- 
dens and  grounds  in  late  summer  and  early 
autumn,  have  an  interesting  history.  Professor 
L.  H.  Bailey  uses  it  as  an  illustration  in  his 
thought-inspiring  book,  “The  Survival  of  the  Unlike;’’  he  says  that  our 
modern  petunias  are  a strange  compound  of  two  original  species; 
the  first  one  was  found  on  the  shores  of  the  La  Plata  in  South  America 
and  was  introduced  into  Europe  in  1823.  “It  is  a plant  of  upright 
habit,  thick  sticky  leaves  and  sticky  stems,  and  very  long-tubed 
white  flowers  . which  exhale  a strong  perfume  at  nightfall.”  The 
second  species  of  petunia  came  from  seeds  sent  from  Argentina  to  the 
Glasgow  Botanical  Gardens  in  1831.  “This  is  a more  compact  plant 
than  the  other,  with  a decumbent  base,  narrower  leaves  and  small,  red- 
purple  flowers  which  have  a very  broad  or  ventricose  tube,  scarcely  twice 
longer  than  the  slender  calyx  lobes.”  This  plant  was  called  Petunia 
violacea  and  it  was  easily  hybridized  with  the  white  species;  it  is  now, 
strangely  enough,  lost  to  cultivation,  although  the  white  species  is  found 
in  some  old  gardens.  The  hybrids  of  these  two  species  are  the  ancestors 
of  our  garden  petunias,  which  show  the  purple-red  and  white  of  their  pro- 
genitors. The  petunias  are  of  the  Nightshade  family  and  are  kin  to 
the  potato,  tomato,  egg-plant,-  tobacco  and  Jimson-weed,  and,  like  the 
latter,  the  flowers  are  especially  adapted  to  give  nectar  to  the  long- 
tongued  sphinx  or  humming  bird  moths. 

The  petunia  corolla  is  tubular,  and  the  five  lobes  open  out  in  salver- 
shape;  each  lobe  is  slightly  notched  at  its  middle,  from  which  point  a 
marked  midrib  extends  to  the  base  of  the  tube.  In  some  varieties  the 
edges  of  the  lobes  are  ruffled.  Within  the  throat  of  the  tube  may  be  seen 
a network  of  darker  veins,  and  in  some  varieties  this  network  spreads  out 
over  the  corolla-lobes.  Although  many  colors  have  been  developed  in 
petunias,  the  red-purple  and  white  still  predominate;  when  the  two  colors 
combine  in  one  flower,  the  pattern  may  be  symmetrical,  but  is  often 
broken  and  blotchy. 


Cultivated-Plant  Study 


641 


When  a flower-bud  is  nearly  ready  to  open  the  long,  bristly  tube  of  the 
corolla  lies  with  its  narrow  base  set  in  the  calyx,  the  long,  fuzzy  lobes  of 
which  flare  out  in  bell-shape ; the  tube  is  marked  by  lengthwise  lines  made 
by  the  five  midribs;  the  lobes  of  the  corolla  are  folded  along  the  outer 
portions  of  these  midribs,  and  these  folded  tips  are  twisted  together  much 
as  if  some  one  had  given  them  a half  turn  with  the  thumb  and  finger.  It 
is  a pleasing  experience  to  watch  one  of  these  flowers  unfold.  When  a 
flower  first  opens,  there  lies  near  the  bottom  of  the  throat  of  the  tube  the 
green  stigma,  with  two  anthers  snuggled  up  in  front  of  it  and  two  behind 
it,  the  latter  being  not  quite  so  advanced  in  age  as  the  former.  As  the 
filaments  of  the  front  pair  of  anthers  are  longer  than  those  of  the  rear  pair, 
the  little  group  lies  at  a low  angle  offering  a dusty  doormat  for  entering 
insects.  If  we  open  a flower  at  this  stage,  we  find  another  anther,  as  yet 
unopened,  and  which  is  on  the  shortest  stamen  of  the  five.  This  seems  to 
be  a little  pollen-reserve,  perhaps  for  its  own  use  later  in  the  season. 
There  is  an  interesting  mechanism  connected  with  these  stamens ; each  is 
attached  to  the  corolla-tube  at  the  base  for  about  half  its  length,  and  at 
the  point  of  attachment  curves  suddenly  inward  so  as  to  “cuddle  up”  to 
the  pistil,  the  base  of  which  is  set  in  the  nectar-well  at  the  bottom  of  the 
flower.  If  we  introduce  a slender  pencil  or  a toothpick  into  the  flower- 
tube  along  the  path  which  the  moth’s  tongue  must  follow  to  reach  the 
nectar,  we  can  see  that  the  stamens,  pressing  against  it  at  the  point  where 
they  curve  inward,  cause  the  anthers  to  move  about  so  as  to  discharge 
their  pollen  upon  it ; and  as  the  toothpick  is  withdrawn  they  close  upon  it 
cogently  so  that  it  carries  off  all  the  pollen  with  which  it  is  brought  in 
contact. 

If  we  look  at  the  stigma  at  the  center  of  its  anther-guard,  it  has  a cer- 
tain close-fisted  appearance,  although  its  outer  edges  may  be  dusted  with 
the  pollen ; as  the  flower  grows  older,  the  stigma  stands  above  the  empty 
anthers  at  the  throat  of  the  flower  tube 
and  opens  out  into  two  distinct  lobes. 

Even  though  it  may  have  accepted  some 
of  its  own  pollen,  it  apparently  opens  up 
a new  stigmatic  surface  for  the  pollen 
brought  from  other  flowers  by  visiting 
insects. 

Dr.  James  G.  Needham  says  that  at 
Lake  Forest  he  has  been  attracted  to  the 
petunia  beds  in  the  twilight  by  the  whir- 
ring of  the  wings  of  countless  numbers  of 
sphinx,  or  hummingbird  moths  which 
were  visiting  these  flowers.  We  also 
may  find  these  moths  hovering  over 
petunia  beds  in  almost  any  region  if  we 
visit  them  on  the  warmer  evenings. 

And  it  is  a safe  guess  that  the  remote 
white  ancestor  of  our  petunias  had  some 
special  species  of  sphinx  moth  which  it 
depended  upon  for  carrying  its  pollen ; 
and  the  strong  perfume  it  exhaled  at  nightfall  was  an  odor  signal  to 
its  moth  friends  to  come  and  feast.

But  even  though  the  petunia  flowers  are  especially  adapted  to  the 
delectation  of  hummingbird  moths,  our  bees  which — like  man — have 
claimed  all  the  earth,  will  work  industriously  in  the  petunias,  scrambling 
into  the  blossoms  with  much  remonstrating,  high-pitched  buzzing  because 
of  the  tight  fit,  and  thus  rifle  the  nectar-wells  that  were  meant  for  insects 
of  quite  different  build. 

The  leaves  of  the  petunia  are  so  broadly  ovate  as  to  be  almost  lozenge- 
shape,  especially  the  lower  ones;  they  are  soft,  and  have  prominent  veins 
on  the  lower  side;  they  are  without  stipules,  and  have  short  flat  petioles. 
The  stems  are  soft  and  fuzzy  and  are  usually  decumbent  at  the  base, 
except  the  central  stems  of  a stool  or  clump  which,  though  surrounded  by 
kneeling  sisters,  seem  to  prefer  to  stand  up  straight. 

The  flower  stems  come  off  at  the  axils  of  the  leaves,  the  lower  flowers 
open  first.  The  blossoms  remain  open  about  two  days;  at  the  first  sign 
of  fading,  the  lobes  of  the  corolla  droop  dejectedly  like  a frill  that  has  lost 
its  starch,  and  finally  the  corolla — tube  and  all — drops  off,  leaving  a little 
conical  seed-capsule  nestled  snugly  in  the  heart  of  the  bell-shaped  calyx. 
At  this  time,  if  this  peaked  cap  of  the  seed-capsule  be  removed,  the  many 
seeds  look  like  tiny  white  pearls  set  upon  the  fleshy,  conical  placenta.  As 
the  capsule  ripens,  it  grows  brown  and  glossy  like  glazed  manila  paper  and 
it  is  nearly  as  thin ; then  it  cracks  precisely  down  its  middle,  and  the  seeds 
are  spilled  out  at  any  stirring  of  the  stems.  The  ripe  seeds  are  dark 
brown,  almost  as  fine  as  dust,  and  yet,  when  examined  with  a lens,  they 
are  seen  to  be  exquisitely  netted  and  pitted.

LESSON  CLXIII 
The  Petunia 

Leading  thought — The  petunias  have  an  interesting  history  being 
native  to  South  America.  Their  flowers  are  fitted  by  form  and  mechanism 
to  entice  the  hummingbird  moths  as  visitors,  and  to  use  them  for  carrying 
pollen. 

Method — The  petunias  are  such  determined  bloomers  that  they  give  us 
flowers  up  to  the  time  of  killing  frosts,  and  they  are  therefore  good  material 
for  nature  lessons.  Each  pupil  should  have  a flower  in  hand  to  observe 
during  the  lesson,  and  should  also  have  access  to  a petunia  bed  for 
observations  on  the  habits  of  the  plant. 

Observations — 1.  What  colors  do  you  find  in  the  petunia  flowers?  If 
striped  or  otherwise  marked,  what  are  the  colors?  Are  the  markings 
symmetrical  and  regular? 

2.  Sketch  or  describe  a flower,  looking  into  it.  What  is  the  shape  of 
the  corolla-lobes?  How  many  lobes  are  there?  How  are  they  veined? 
What  peculiar  markings  are  at  the  throat  of  the  flower? 

3.  What  are  the  color  and  position  of  the  stigma?  How  are  the 
stamens  arranged  ? How  many  anthers  do  you  see  ? What  is  the  color 
of  the  anthers  ? Of  the  pollen  ? 

4.  Sketch  or  describe  the  flower  from  the  side.  What  is  the  shape  of 
the  corolla-tube ? Is  it  smooth  or  fuzzy?  How  is  it  marked ? What  are 
the  number  and  shape  of  the  sepals,  or  lobes,  of  the  calyx?

5.  Study  a freshly  opened  flower,  and  describe  the  position  and 
appearance  of  the  anthers  and  stigma.  Do  they  remain  in  these  relative 
positions  after  the  flower  is  old  ? 

6.  Cut  open  a flower,  slitting  it  along  the  upper  side.  Describe  the 
stamens  and  how  they  aj-e  attached.  Is  the  pistil  attached  in  the  same 
manner?  Where  is  the  nectar?  Thrust  a slender  pencil  or  a toothpick 
into  the  tube  of  a fresh  flower.  Does  this  spread  the  anthers  apart  and 
move  them  around ? When  it  is  withdrawn,  is  there  pollen  on  it?  Can 
you  see  in  your  open  flower  the  mechanism  by  which  the  pollen  is  dusted 
on  the  object  thrust  into  the  flower? 

7.  What  insects  have  tongues  sufficiently  long  to  reach  the  nectar- 
well  at  the  bottom  of  the  petunia  flower?  At  what  time  do  these  insects 
fly  ? At  what  time  of  day  do  most  of  the  petunia  flowers  open  ? Visit  the 
petunia  beds  in  the  twilight,  and  note  whether  there  are  any  insects  visit- 
ing them.  What  insects  do  you  find  visiting  these  flowers  during  the  day  ? 

8.  Sketch  or  describe  the  leaves  of  the  petunia.  How  do  the  leaves 
feel  ? Look  at  a leaf  with  a lens  and  note  the  fringe  of  hair  along  its  edges. 
Describe  the  veining  of  the  leaf. 

9.  Describe  the  petunia  s.tems.  Are  they  stout  or  slender?  How  do 
they  feel?  With  what  are  they  covered?  Where  do  the  flower  stems 
come  off  the  main  stalk  ? 

10.  Describe  or  sketch  a flower-bud  just  ready  to  open.  How  are  the 
tips  of  the  lobes  folded?  How  long  does  the  flower  remain  in  bloom? 
What  is  the  first  sign  of  its  fading? 

nr  Describe  the  seed-capsule.  Where  does  it  open  ? Are  the  seeds 
many  or  few,  large  or  small?  What  is  their  color  when  ripe?  When 
examined  with  a lens,  have  they  any  pits  or  markings? 


THE  HORSESHOE  GERANIUM 
Teacher's  Story 

The  geraniums  perhaps  do  more  to  brighten  the  world  than  almost  any 
other  cultivated  flowers.  They  will  grow  for  every  one,  whether  for  the 
gardener  in  the  conservatory  of  the  rich,  or  in  a tin  can  on  the  windowsill 
of  the  crowded  tenement  of  the  poor.  And  it  is  interesting  to  know  that 
this  common  plant  has  a cultivated  ancestry  of  two  hundred  years’ 
standing  These  geraniums,  which  are  really  not  geraniums  botanically 
but  are  pelargoniums , originally  came  from  southern  Africa,  and  the  two 
ancestors  of  our  common  bedding  geraniums  were  introduced  into  England 
in  1710  and  1714. 

The  geranium  is  of  special  value  to  the  teacher,  since  it  is  available  for 
study  at  any  season  of  the  year,  and  has  a most  interesting  blossom.  The 
single-flowered  varieties  should  be  used  for  this  lesson,  since  the  blossoms 
that  are  double  have  lost  their  original  form.  Moreover,  the  geranium’s 
blossom  is  so  simple  that  it  is  of  special  value  as  a subject  for  a beginning 
lesson  in  teaching  the  parts  of  a flower;  and  its  leaves  and  stems  may 
likewise  be  used  for  the  first  lessons  in  plant  structure. 

The  stem  is  thick  and  fleshy , and  is  downy  on  the  new  growth ; there  is 
much  food  stored  in  these  stems,  which  accounts  for  the  readiness  with 
which  cuttings  from  them  will  grow.  Wherever  a leaf  comes  off  the  stem, 
it  is  guarded,  by  two  stipules  at  the  base;  these  stipules  often  remain  after

the  leaves  have  fallen,  thus  giving  the  stem  an  unkempt  look.  The 
leaves  are  of  various  shapes,  although  of  one  general  pattern;  they  are 
circular  and  beautifully  scalloped  and  lobed,  with  veins  for  every  lobe 
radiating  from  the  petiole;  they  are  velvety  above  and  of  quite  different

Note  the  positions  of  the  opened  flowers  and  the  buds.  Note  the  shape  of  the  two  upper 
petals  with  their  guide-lines,  showing  the  position  of  the  nectar-gland.  The  flower  at  the  left,  seen 
in  profile,  shows  that  these  upper  petals  project  farther  forward  than  those  below.  Note.,,  the 
cluster  of  young  buds  set  in  a circlet  of  bracts  just  below  this  flower. 


texture  beneath,  and  many  show  the  dark  horseshoe  which  gives  the  name 
to  this  variety.  The  petiole  is  usually  long  and  stiff  and  the  leaves  are  set 
alternately  upon  the  stem. 

The  flower  has  five  petals,  and  at  first  glance  they  seem  of  much  the 
same  shape  and  position ; but  if  we  look  at  them  carefully,  we  see  that  the 
upper  two  are  much  narrower  at  the  base  and  project  farther  forward  than

do  the  lower  three . Moreover,  there  are  certain  lines  on  these  upper  petals 
all  pointing  toward  the  center  of  the  flower;  these  are  the  nectar  guide- 
lines, and  if  we  follow  them  we  find  a deep 
nectar-well  just  at  the  base  of  these  upper 
petals  and  situated  above  the  ovary  of 
the  flower.  No  other  flower  shows  a 
prettier  plan  for  guiding  insects  to  the 
hidden  sweets,  and  in  none  is  there  a 
more  obvious  and  easily  seen  well  of 
nectar.  It  extends  almost  the  whole 
length  of  the  flower  stem,  the  nectar 
gland  forming  a hump  near  the  base  of 
the  stem.  If  we  thrust  a needle  down 
the  whole  length  of  this  nectar  tube  we 
can  see  that  this  bright  flower  developed 
its  nectar  especially  for  some  long-tongued 
insect,  probably  a butterfly.  It  is  inter- 
esting to  note  that  in  the  double  geranium 
where  the  stamens  have  been  all  changed 
to  petals  and  where,  therefore,  no  seeds 
are  formed,  this  nectar-well  has  been  lost. 

There  are  five  sepals,  the  lower  one 
being  the  largest.  But  the  geranium 
is  careless  about  the  number  of  its  sta- 
mens; most  flowers  are  very  good  mathe- 
maticians, and  if  they  have  five  sepals 
and  five  petals  they  are  likely  to  have  five  or  ten  stamens.  The  geranium 
often  shows  seven  anthers,  but  if  we  look  carefully  we  may  find  ten 
stamens,  three  of  them  without  anthers.  But  this  is  not  always 
true;  there  are  sometimes  five  anthers  and  two  or  three  filaments 
without  anthers.  The  color  of  the  anthers  differs  with  the  variety 
of  the  flower.  The  stamens  broaden  below,  and  their  bases  are 
joined  making  a cup  around  the  lower  part  of  the  ovary.  The 
pistil  is  at  the  center  of  the  flower  and  has  no  style,  but  at  the 
summit  divides  into  five  long,  curving  stigmas;  but  again  the 
geranium  cannot  be  trusted  to  count,  for  sometimes  there  are 
seven  or  eight  stigmas.  Although  many  of  our  common  varieties 
of  geraniums  have  been  bred  so  long  that  they  have  almost  lost 
the  habit  of  producing  seed,  yet  we  may  often  find  in  these  single  blossoms 
the  ovary  changed  into  the  peculiar,  long,  beaklike  pod,  which  shows  the 
relationship  of  this  plant  to  the  cranesbill  or  wild  geranium. 

When  the  buds  of  the  geranium  first  appear,  all  of  them  are  nestled  in 
a nest  of  protecting  bracts,  each  bud  being  enclosed  in  its  own  protecting 
sepals.  But  soon  each  flower  stem  grows  longer  and  droops  and  often  the 
bracts  at  its  base  fall  off ; from  this  mass  of  drooping  buds,  the  ones  at  the 
center  of  the  cluster  lift  up  and  open  their  blossoms  first.  Often,  when 
the  outside  flowers  are  in  bloom,  those  at  the  center  have  withered  petals 
but  are  hidden  by  their  fresher  sisters. 

It  would  be  well  to  say  something  to  the  pupils  about  those  plants 
which  have  depended  upon  man  so  long  for  their  planting  that  they  do 
not  develop  any  more  seed  for  themselves.  In  connection  with  the 
geraniums,  there  should  be  a lesson  on  how  to  make  cuttings  and  start

their  growth.  The  small  side  branches  or  the  tips  of  the  main  stems  may 
be  used  as  cuttings.  With  a sharp  knife  make  a cut  straight  across.  Fill 
shallow  boxes  with  sand,  place  them  in  a cool  room  and  keep  them  con- 
stantly moist ; plant  the  cuttings  in  these  boxes,  putting  the  stems  for  one- 
third  of  their  length  in  the  sand.  After  about  a month  the  plants  may  be 
repotted  in  fertile  soil.  The  fall  is  the  best  time  to  make  cuttings. 


LESSON  CLXIV 
The  Horseshoe  Geranium 

Leading  thought — The  geraniums  are  very  much  prized  as  flowers  for 
ornamental  beds.  Let  us  see  why  they  are  so  valued. 

Method — A variety  of  geranium  with  single  flowers  should  be  chosen 
for  this  purpose,  and  it  may  be  studied  in  the  schoolhouse  window  or  in 
the  garden.  As  the  parts  of  this  flower  are  of  a very  general  type,  it  is  an 
excellent  one  with  which  to  teach  the  names  and  purposes  of  the  flower 
parts.  Each  child  can  make  a little  drawing  of  the  sepals,  petals,  stamens 
and  pistil,  and  label  them  with  the  proper  names. 

Observations — 1 . What  sort  of  a stem  has  the  geranium.  Is  it  smooth 
or  downy  ? What  makes  the  geranium  stem  look  so  rough  and  untidy? 

2.  Study  the  leaf.  Show  by  description  or  drawing  its  shape,  its 
wings,  its  veins.  What  are  its  colors  and  texture  above ? Beneath?  Is 
the  petiole  long  or  short  ? What  grows  at  the  base  of  the  petiole  where  it 
joins  the  stem?  What  marking  is  there  on  the  leaf,  which  makes  us  call 
this  a “horseshoe  geranium?”  Are  there  other  geraniums  with  leaves  of 
similar  shape  that  have  no  horseshoe  mark? 

3.  Study  the  flower.  Are  the  petals  all  the  same  size  and  shape? 
How  many  of  them  are  broad?  How  many  narrow?  Do  the  narrow 


Cultivated-Plant  Study 


647 


ones  project  in  front  of  the  others  ? Do  these  have  guide-lines  upon  them  ? 
Where  do  these  lines  point?  Find  the  nectar- well,  how  deep  is  it?  Does 
it  extend  almost  the  entire  length  of  the  flower  stem?  For  what  insects 
must  it  have  been  developed?  Are  there  nectar-tubes  in  the  stems  of 
the  geraniums  with  double  flowers?  Why? 

4.  How  many  sepals  are  there ? Are  they  all  the  same  size ? Where 
is  the  largest? 

5.  How  many  stamens  can  you  see?  What  is  the  color  of  the  fila- 
ments and  of  the  anthers?  How  are  the  stamens  joined  at  their  bases? 
Can  you  find  any  stamens  without  anthers  ? 

6.  Where  is  the  pistil  situated  ? Can  you  see  the  ovary,  or  seed-box  ? 
How  many  stigmas?  Describe  their  color  and  shape. 

7 . In  what  part  of  the  flower  will  the  seeds  be  developed  ? H-ow  does 
the  geranium  fruit  look?  Sketch  the  pod.  Do  the  geraniums  develop 
many  seeds?  Why  not?  Do  you  know  the  seed-pod  of  the  wild  gera- 
nium? If  so,  compare  it  with  the  pod  of  this  plant. 

8.  Take  a flower  cluster  when  the  flowers  are  all  in  the  bud,  and  note 

the  following:  When  the  buds  first  appear,  what  protects  them?  What 

becomes  of  these  bracts  later?  How  do  the  sepals  protect  the  bud  ? Are 
the  bud  stems  upright  and  stiff  or  drooping?  How  many  buds  are  there 
in  a cluster? 

9.  Take  notes  on  successive  days  as  follows : What  happens  to  the 
stem  as  the  bud  gets  ready  to  bloom  ? Is  it  a central  or  an  outside  blossom 
that  opens  first?  How  many  new  blossoms  are  there  each  day?  How 
long  is  it  from  the  time  that  the  first  bud  opens  until  the  last  bud  of  the 
cluster  blossoms?  What  has  this  to  do  with  making  the  geranium  a 
valuable  ornamental  plant  ? 

10.  Make  some  geranium  cuttings,  and  note  how  they  develop  into 
new  plants.  Place  one  of  the  cuttings  in  a bottle  of  water  and  describe 
how  its  roots  appear  and  grow. 


“God  made  the  flowers  to  beautify 
The  earth,  and  cheer  man's  careful  mood; 
And  he  is  happiest  who  hath  power 
To  gather  wisdom  from  a flower, 

And  wake  his  heart  in  every  hour 
To  pleasant  gratitude .” 

— Wordsworth.

THE  SWEET  PEA 


Teacher's  Story 


MONG  the  most  attractive  of  the  seeds  which 
make  up  the  treasure  of  the  children  s seed 
packets,  the  sweet  peas  are  of  the  prettiest. 
They  are  smooth,  little  white  or  brown 
globules,  marked  with  a scar  on  the  side,  showing  where 
they  were  attached  to  the  pod.  One  of  these  peas  divides 
readily  into  two  sections ; and  after  it  has  been  soaked  in 
water  for  twenty-four  hours,  the  germ  of  the  future  plant 
may,  with  the  aid  of  a lens,  be  seen  within  it.  After 
planting,  the  sprout  pushes  through  the  seed-coat  at  a 
point  very  near  the  scar,  and  leaf  shoots  emerge  from 
the  same  place ; but  the  two  act  very  differently . The  leaf  lifts 
upward  toward  the  light,  and  the  root  plunges  down  into  the  soil. 
As  the  plant  grows,  it  absorbs  the  food  stored  in  the  seed;  but  the  seed 
remains  below  ground  and  does  not  lift  itself  into  the  air,  as  happens  with 
the  bean.  The  root  forms  many  slender  branches,  near  the  tips  of  which 
may  be  seen  the  fringe  of  feeding  roots,  which  take  up  the  food  and  water 
from  the  soil.  The  first  leaves  of  the  pea  seedling  put  forth  no  tendrils, 
but  otherwise  look  like  the  later  ones.  The  leaves  grow  alternately  on  the 
stalk,  and  they  are  compound,  each  having  from  three  to  seven  leaflets. 
The  petiole  is  winged,  as  is  also  the  stem  of  the  plant.  There  is  a pair  of 
large,  clasping  stipules  at  the  base  of  each  leaf.  If  we  compare  one  of 
these  leaves  with  a spray  of  tendrils,  we  can  see  that  they  resemble  each 
other  in  the  following  points : The  basal  leaflets  of  the  petiole  are  similar 

and  the  stipules  are  present  in  each  case ; but  the  leaflets  nearest  the  tip 
are  marvelously  changed  to  little,  stiff  stems  with  a quirl  at  the  tip  of  each 
ready  to  reach  out  and  hook  upon  any  object  that  offers  surface  to  cling 
to.  Sometimes  we  find  a leaflet  paired  with  a tendril.  The  sweet  pea 
could  not  thrive  without  a support  outside  of  itself. 

Of  course,  the  great  upper  petal  of  the  sweet  pea  blossom  is  called  the 
banner!  It  stands  aloft  and  proclaims  the  sweet  pea  as  open ; but  before 
this  occurs,  it  tenderly  enfolds  all  the  inner  part  of  the  flower  in  the 
unopened  bud,  and  when  the  flower  fades  it  again  performs  tnis  duty. 
The  wings  are  also  well  named;  for  these  two  petals  which  hang  like  a 
peaked  roof  above  the  keel,  seem  like  wings  just  ready  to  open  in  flight, 
The  two  lower  petals  are  sewed  together  in  one 
of  Nature’s  invisible  seams,  making  a long, 
curved  treasure  chest  resembling  the  keel  of  a 
boat,  and  it  has  thus  been  called.  Within  the 
keel  are  hidden  the  pistil  and  stamens.  The 
ovary  is  long,  pod-shaped  and  downy;  from 
its  tip  the  style  projects,  as  strong  as  a wire, 
curving  upwards,  and  covered  with  a brush  of 
fine,  white  hairs;  at  the  very  tip  of  the  style, 
and  often  projecting  slightly  from  the  keel,  is 
the  stigma.  Around  the  sides  and  below  the 
ovary  and  style,  are  nine  stamens,  their  fila- 
ments broadening  and  uniting  to  make  a white,  silken  tube  about  the 
ovary,  or  young  pod.  From  the  tip  of  this  stamen -tube,  each  of  the  nine

filaments  disengages  itself,  and  lying  close  to  the  style  thrusts  its  anther 
up  into  the  point  ot  the  keel,  below  the  stigma.  But  strange  to  say,  one 
lone,  lorn  stamen  “flocks  by  itself”  above  the  pistil,  curving  its  anther  up 
stigma-ward.  If  we  touch  the  point  of  the  keel  with  the  finger,  up  fly — like 
a jack-in-the-box — the  anthers  splashing  the  finger  with  pollen;  and  if  a 
bee,  in  her  search  for  nectar,  alights  on  the  wings  at  the  very  base  of  the 
petals,  up  flies  the  pollen  brush  and  daubs  her  with  the  yellow  dust,  which 

she  may  deposit  on  the  stigma  of 
another  flower.  The  interesting 
part  of  this  mechanism  is  the 
brush  near  the  tip  of  the  style 
below  the  stigma — a veritable 
broom,  with  splints  all  directed 
upward.  As  the  pollen  is  dis- 
charged around  it,  the  brus-h 
lifts  it  up  when  the  keel  is  pressed 
down,  and  the  stiff  petals  form- 
ing the  keel,  in  springing  back  to 
place,  scrape  off  the  pollen  and 
plaster  it  upon  the  visitor.  But 
for  all  this  elaborate  mechanism, 
sweet  peas,  of  all  flowers,  are  the 
Sweet  pea  pod  bursting  in  spiral.  most  difficult  to  cross-pollenate, 

since  they  are  so  likely  to  receive 
some  of  their  own  pollen  during  this  process. 

The  sweet-pea  bud  droops,  a tubular  calyx  with  its  five-pointed  lobes 
forming  a bell  to  protect  it.  Within  the  bud  the  banner  petal  clasps  all  in 
its  protecting  embrace. 

After  the  petals  fall,  the  young  pod  stands  out  from  the  calyx,  the  five 
lobes  of  which  are  recurved  and  remain  until  the  pod  is  well  grown.  As 
the  sweet  pea  ripens,  all  the  moisture  is  lost  and  the  pod  becomes  dry  and 
hard,  through  the  dampness  of  dews  at  night  and  the  sun’s  heat  which 
warps  it  by  day,  finally  each  side  of  the  pod  suddenly  coils  into  a spiral, 
flinging  the  seed  many  feet  distant  in  different  directions. 

LESSON  CLXV 
The  Sweet  Pea 

Leading  thought — The  sweet  pea  has  its  leaflets  changed  to  tendrils, 
which  hold  it  to  the  trellis.  Its  flower  is  like  that  of  the  clover,  the  upper 
petal  forming  the  banner,  the  two  side  petals  the  wings,  and  the  two 
united  lower  petals  the  keel  which  protects  the  stamens  and  pistil. 

Method — This  should  be  a garden  lesson.  A study  should  be  made  of 
the  peas  before  they  are  planted,  and  their  germination  carefully  watched. 
Later,  the  method  of  climbing,  the  flower  and  the  fruit  should  each  be  the 
subject  of  a lesson. 

Observations  on  germination — i.  Soak  some  sweet  peas  over  night ; 
split  them  the  next  morning.  Can  you  see  the  little  plant  within  ? 

2.  Plant  some  of  the  soaked  peas  in  cotton  batting,  which  may  be 
kept  moist.  At  what  point  does  the  sprout  break  through  the  seed  cover- 
ing? Do  the  root  and  leaf-shoot  emerge  at  the  same  place,  or  at  differ- 
ent points?  Which  is  the  first  to  appear?

3.  Plant  some  of  the  soaked  peas  in  the  garden.  How  do  the 
young  plants  look  when  they  first  appear?  Does  the  fleshy  part  of  the 
seed  remain  a part  of  the  plant  and  appear  above  the  ground,  as  is 
the  case  with  the  bean  ? What  becomes  of  the  meat  of  the  seed  after 
growth  has  started? 

4.  Do  the  first  leaves  which  unfold  from  the  seed  pea  look  like  the 
later  ones?  Are  the  leaves  simple  or  compound?  Do  they  grow 
opposite  each  other  or  alternately? 

5.  Take  a leaf  and  also  a spray  of  the  tendrils.  How  many  leaflets 
are  there  in  a compound  leaf?  Describe  the  petiole  and  the  basal  leaves. 
How  far  apart  are  the  leaflets  on  the  mid-stem?  Compare  the  stem 
on  which  the  tendrils  grow  with  this  leaf.  Are  the  basal  leaflets  like 
those  of  the  leaf?  Is  the  petiole  like  that  of  the  leaf?  Do  you  think  that 
the  leaflets  toward  the  tip  of  the  stem  often  change  to  tendrils? 
Why  do  you  think  so?  Why  must  the  sweet  pea  have  tendrils?  Do 
you  see  the  earlike  stipules  at  the  base  of  the  leaf?  Are  there  similar 
stipules  at  the  base  of  the  tendril  stem? 

Observations  on  the  flower  and  fruit — 1 . Take  the  sweet  pea  in  blossom . 
Why  is  the  large  upper  petal  called  the  banner?  How  does  it  compare 
in  size  with  the  other  petals?  What  is  its  purpose  when  the  flower  is 
open  ? Why  do  you  think  the  side  petals  are  called  wings  ? What  is  their 
position  when  the  flower  is  open? 

2.  Describe  that  part  of  the  flower  below  the  wings.  Do  you  think 
that  it  is  made  of  two  petals  grown  together?  Why  is  it  called  the  keel  of 
the  flower?  Press  down  with  your  finger  on  the  tip  of  the  keel.  What 
happens?  Is  your  finger  splashed  with  pollen?  Where  is  the  nectar  in 
the  sweet  pea?  Would  an  insect  getting  the  nectar  press  down  upon  the 
keel  and  receive  a splash  of  pollen? 

3.  Open  the  keel.  How  many  stamens  do  you  find  within  it  ? How 
many  have  their  filaments  joined  together?  Is  there  one  separate  from 
the  others?  Against  what  are  the  anthers  pressed  by  the  keel? 

4.  Remove  the  stamens  and  describe  the  pistil.  Which  part  of  this 
will  make  the  pod  in  which  the  new  peas  will  develop  ? Describe  how  the 
style  is  curved.  How  is  the  style  covered  near  its  tip?  What  is  this 
brush  for  ? Can  you  find  the  stigma  with  the'  help  of  the  lens  ? When  the 
bee  is  seeking  for  nectar  and  pushes  down  on  the  keel,  does  the  stigma 
push  out  at  the  same  point  as  the  pollen?  Does  this  enable  the  stigma 
sometimes  to  receive  pollen  which  the  bees  bring  from  other  flowers? 

5.  Describe  an  unopened  flower  bud.  What  is  its  position?  How 
many  lobes  to  the  calyx?  What  is  their  shape,  and  how  do  they  protect 
the  bud ? Which  petal  is  folded  over  all  the  others?  How  does  the  posi- 
tion of  the  open  flower  differ  from  that  of  the  bud  ? 

6.  How  does  the  young  pod  look  when  the  petals  fall?  How  does  it 
look  when  ripe  ? How  does  it  open  to  scatter  little,  ripe  sweet  peas  ? Do 
the  lobes  of  the  sepals  still  remain  with  the  pod?

THE  CLOVERS 
Teacher's  Story 

11  Sweet  by  the  roadside , sweet  by  the  rills , 

Sweet  in  the  meadows , sweet  on  the  hills, 

Sweet  in  its  wine,  sweet  in  its  red, 

Oh,  half  of  its  sweetness  cannot  be  said; 

Sweet  in  its  every  living  breath. 

Sweetest,  perhaps,  at  last,  in  death." 

— “A  Song  of  Clover”,  Helen  Hunt  Jackson. 

Clover  has  for  centuries  been  a most  valv. 
able  forage  crop ; and  for  eons  it  has  been  the 
special  partner  of  the  bees,  giving  them  honey 
for  their  service  in  carrying  its  pollen ; and  in 
recent  years  it  has  been  discovered  that  it  has 
also  formed  a mysterious  and  undoubtedly  an 
ancient  partnership  with  bacteria  below 
ground,  which,  moreover, brings  fertility  to  the 
soil.  The  making  of  a collection  of  the  clovers 
of  a region  is  a sure  way  of  enlisting  the  pupils’ 
interest  in  these  valuable  plants.  The  species 
have  some  similarities  and  differences,  which 
give  opportunity  for  much  observation  in 
comparing  them.  There  may  be  found  in 
most  localities  the  white  and  yellow  sweet 
clovers,  the  black  and  spotted  medics  and 
their  relative  the  alfalfa;  while  of  the  true 
clovers  there  are  the  red,  the  zigzag,  the 
buffalo,  the  rabbit’s  foot,  the  white,  the  alsike,

In  all  the  clovers,  those  blossoms  which  are 
lowest,  or  on  the  outside  of  the  head,  blossom  first,  and  all  of  them  have

upon  their  roots  the  little  swellings,  or  nodules,  which  are  the  houses  in 
which  the  beneficent  bacteria  grow. 

If  we  pull  up  or  dig  out  the  roots  of  alfalfa,  or  of  the 
true  clovers  or  vetches,  we  find  upon  the  rootlets  little 
swellings  which  are  called  nodules,  or  root-tubercles. 

Although  these  tubercles  look  so  uninteresting,  no  fairy 
story  was  ever  more  wonderful  than  is  theirs.  They  are, 
in  fact,  the  home  of  the  clover  brownies,  which  help  the 
plants  to  do  their  work.  Each  nodule  is  a nestful  of  liv- 
ing beings,  so  small  that  it  would  take  twenty-five 
thousand  of  them  end  to  end  to  reach  an  inch;  therefore, 
even  a little  swelling  can  hold  many  of  these  minute 
organisms,  which  are  called  bacteria.  For  many  years 
people  thought  that  these  swellings  were  injurious  to  the 
roots  of  the  clover,  but  now  we  know  that  the  bacteria 
which  live  in  them  are  simply  underground  partners  of 
these  plants.  The  clover  roots  give  the  bacteria  homes 
and  place  to  grow,  and  in  return  these  are  able  to  extract 
a very  valuable  chemical  fertilizer  from  the  air,  and  to 
change  its  form  so  that  the  clovers  can  absorb  it.  The 
name  of  this  substance  is  nitrogen,  and  it  makes  up  more 
than  three-fourths  of  the  air  we  breathe.  Other  plants 
are  unable  to  take  the  nitrogen  from  the  air  and  use  it  for 
food,  but  these  little  bacteria  extract  it  from  the  air  which 
fills  every  little  space  between  every  two  grains  of  soil  and 
then  change  it  to  a form  which  the  clovers  can  use. 

After  the  clover  crop  is  h arvested,  the  roots  remain  in  the 
ground,  their  little  storehouses  filled  with  this  precious 
substance,  and  the  soil  falls  heir  to  it. 

Nitrogen  in  the  form  of  commercial  fertilizer  is  the 
most  expensive  which  the  farmer  has  to  buy.  So  when 
he  plants  clover  or  alfalfa  on  his  land,  he  is  bringing  to  the 
soil  this  expensive  element  of  plant  growth,  and  it  costs  Alfalfa  showing 
him  nothing.  This  is  why  a good  farmer  practices  the  root-tubercles. 
rotation  of  crops  and  puts  clover  upon  his  land  every  three  or  four  years.

Handbook  of  Nature-Study 


Alfalfa  is  so  dependent  on  its  little  underground  partners,  that  it 
cannot  grow  without  them;  and  so  the  farmer  plants,  with  the  alfalfa 
seed,  some  of  the  soil  from  an  old  alfalfa  field,  which  is  rich  in  these  bac- 
teria. On  a farm  I know,  the  bacterial 
soil  gave  out  before  all  of  the  seed  was 
planted ; and  when  the  crop  was  ready 
to  cut  it  was  easy  to  see  just  where  the 
seed  without  the  inoculated  soil  had 
been  planted,  for  the  plants  that  grew 
there  were  small  and  poor,  while  the 
remainder  of  the  field  showed  a luxu- 
rious growth. 

It  is  because  of  the  great  quantity  of 
nitrogen  absorbed  from  the  air  through 
the  bacteria  on  its  roots  that  the  alfalfa 
is  such  a valuable  fodder;  for  it  con- 
tains the  nitrogen  which  otherwise 
would  have  to  be  furnished  to  cattle  in 
expensive  grain  or  cotton-seed  meal. 
The  farmer  who  gives  his  stock  alfalfa 
does  not  need  to  pay  such  large  bills 
for  grain.  Other  plants  belonging  to 
the  same  family  as  the  clovers — like 
the  vetches  and  cow-peas — also  have 
bacteria  on  their  roots.  But  each 
species  of  legume  has  its  own  species  of 
bacteria;  although  in  some  cases  soil 
inoculated  with  bacteria  from  one 
species  of  legume  will  grow  it  on  roots 
of  another  species.  Thus,  the  bacteria 
on  the  roots  of  sweet  clover  will  grow 
on  the  roots  of  alfalfa  and  many  farmers 
use  the  soil  inoculated  by  sweet  clover 
to  start  their  alfalfa  crops. 

In  addition  to  the  enriching  of  the  soil,  clover  roots,  which  penetrate 
very  deeply,  protect  land  from  being  washed  away  by  freshets  and  heavy 
rains ; and  since  clover  foliage  makes  a thick 
carpet  over  the  surface  of  the  soil,  it  pre- 
vents evaporation  and  thus  keeps  the  soil 
moist.  Crimson  clover  is  used  extensively 
as  a cover  crop ; it  is  sowed  in  the  fall, 
especially  where  clean  culture  is  practiced 
in  orchards,  and  spreads  its  leaves  above 
and  its  roots  within  the  soil,  keeping  out 
weeds  and  protecting  the  land.  In  the 
spring  it  may  be  plowed  under,  and  thus 
add  again  to  the  fertility.  This  is  also  an 
aesthetic  crop,  for  a field  of  crimson  clover 
in  bloom  is  one  of  the  most  beautiful  sights 
in  our  rural  landscape. 

Red  clover  has  such  deep  florets  that, 
of  all  our  bees,  only  the  bumblebees  have  Red  cljver  blossom.

sufficiently  long  tongues  to  reach  the  nectar. 

It  is,  therefore,  dependent  upon  this  bee  for 
developing  its  seed,  and  the  enlightened  farmer 
of  to-day  looks  upon  the  bumblebees  as  h;  , 
best  friends.  The  export  of  clover  seed  frc_n 
the  United  States  has  sometimes  reached  the 
value  of  two  million  dollars  per  year,  and  this 
great  industry  can  only  be  carried  on  with  the 
aid  of  the  bumblebee.  There  are  sections  of 
New  York  State  where  the  growing  of  clover 
seed  was  once  a most  profitable  business,  but 
where  now,  owing  to  the  dearth  of  bumblebees, 
no  clover  seed  whatever  is  produced. 

LESSON  CLXVI 
The  Clovers 

Leading  thought — The  clovers  enrich  with  nitrogen  the  soil  in  which 
they  are  planted.  They  are  very  valuable  as  food  for  stock;  and  their 
flowers  are  pollenated  by  bees. 

Method — Each  pupil  should  dig  up  a root  of  red  clover  or  alfalfa  to  use 
for  the  lesson  on  the  nodules.  The  flowers  should  be  studied  in  the  field, 
and  also  in  detail  in  the  schoolroom. 

Observations — i.  How  many  kinds  of  clover  do  you  know?  How 
many  of  the  medics  ? 

2.  In  all  clovers,  which  flowers  of  the  head  blossom  first,  those  on  the 
lower  or  outside,  or  those  on  the  upper  or  inside  ? 

3.  Take  up  a root  of  red  clover  or  alfalfa,  noting  how  deep  it  grows. 
Wash  the  root  free  from  soil,  and  find  the  little  swellings  on  it.  Write  the 
story  of  what  these  swellings  do  for  the  clover,  and  incidentally  for  the 
soil. 

4.  How  must  the  soil  be  prepared  so  that  afalfa  may  grow  success- 
fully? What  does  the  farmer  gain  by  feeding  alfalfa,  and  why? 

5.  How  do  clover  roots  protect  the  land  from  being  washed  by  heavy 
rains  ? 

6.  How  do  clovers  keep  the  soil  moist?  How  does  this  aid  the 
farmer? 

7.  What  is  a cover  crop,  and  what  are  its  uses? 

8.  Upon  what  insects  does  the  red  clover  depend  for  carrying  pollen  ? 
Can  it  produce  seed  without  the  aid  of  these  valuable  bees?  Why  not  ? 


SWEET  CLOVER 
Teacher's  Story 

In  passing  along  the  country  roads,  especially  those  which  have 
suffered  upheaval  from  the  road  machines,  suddenly  we  are  conscious  of 
a perfume  so  sweet,  so  suggestive  of  honey  and  other  delicate  things, 
that  we  involuntarily  stop  to  find  its  source.  Close  at  hand  we  find  this 
perfume  laboratory  in  the  blossoms  of  the  sweet  clover.  It  may  be 
the  species  with  white  blossoms,  or  the  one  with  yellow  flowers,  but 
the  fragrance  is  the  same.  There  stands  the  plant,  lifting  its  beautiful

blue-green  foliage  and  its  spikes  of  flowers  for 
the  enjoyment  of  the  passer-by,  while  its  roots 
are  feeling  their  way  down  deep  in  the  poor, 
hard  soil,  taking  air  and  drainage  with  them 
and  building,  with  the  aid  of  their  underground 
partners,  nitrogen  factories  which  will  enrich 
the  poverty-stricken  earth,  so  that  other 
plants  may  find  nourishment  in  it. 

Never  was  there  such  another  beneficent 1 
weed  as  the  sweet  clover — beneficent  alike  to 
man,  bee  and  soil.  Usually  we  see  it  growing 
on  soil  so  poor  that  it  can  only  attain  a height 
of  from  two  to  four  feet;  but  if  it  once  gets 
foothold  on  a generous  soil,  it  rises  majestically 
ten  feet  tall. 

Like  the  true  clover,  its  leaf  has  three 
leaflets,  the  middle  one  being  longer  and 
larger  than  the  other  two  and  separated  from 
them  by  a naked  midrib;  the  leaflets  are  long, 
oval  in  shape,  with  narrow,  toothed  edges, 
and  they  are  dull,  velvety  green;  the  two 
stipules  at  the  base  of  the  leaf  are  little  and 
pointed. 

The  blossoming  of  the  sweet  clover  is  a 
pretty  story.  The  blossom  stem,  which 
comes  from  the  axil 


of  the  leaf,  is  at  first  an  inch  or  so  long, 
packed  closely  with  little,  green  buds  hav- 
ing pointed  tips.  But  as  soon  as  the  blos- 
soming begins,  the  stem  elongates,  bring- 
ing the  flowers  farther  apart — just  as  if 
the  buds  had  been  fastened  to  a rubber  cord 
which  had  been  stretched.  The  buds  lower 
down  open  first ; each  day  some  of  the  flowers 
bloom,  while  those  of  the  day  before  linger, 
and  thus  the  blossom  tide  rises,  little  by  little 
up  the  stalk.  But  the  growing  tip  develops 
more  and  more  buds,  and  thus  the  blossom 
story  continues  until  long  after  the  frosts  have 
killed  most  other  plants;  finally  the  tip  is 
white  with  blossoms,  while  the  seeds  developed 
from  the  first  flowers  on  the  plant  have  been 
perfected  and  scattered. 

The  blossom  is  very  much  like  a diminutive 
sweet  pea;  the  calyx  is  like  a cup  with  five 
points  to  its  rim,  and  is  attached  to  the  stalk 
by  a short  stem.  The  banner  petal  is  larger 
than  the  wings  and  the  keel . A lens  shows  the 
stamens  united  into  two  groups,  with  a thread- 
like pistil  pushing  out  between ; both  stamens 
and  pistil  are  covered  by  the  keel,  as  in  the  pea 
blossom.

The  flowers  are  beloved  by  bees  and  many  other  insects,  which  are 
attracted  to  them  by  their  fragrance  as  well  as  by  the  white  radiance  of 
their  blossoms.  The  ripened  pod  is  well  encased  in  the  calyx  at  its 
base.  The  foliage  of  the  sweet  clover  is  fragrant,  especially  so  when 
drying;  it  has  been  used  for  fodder.  The  6weet  clovers  came  to  us  from 
Europe  and  are,  in  a measure,  compensation  for  some  of  the  other 
emigrant  weeds  which  we  wish  had  remained  at  home. 

LESSON  CLXVII 
Sweet  Clover 

Leading  thought - — This  beneficent  plant  grows  in  soil  too  poor  for  other 
plants  to  thrive  in.  It  brings  nitrogen  and  air  into  the  soil,  and  thus 
makes  it  fertile  so  that  other  plants  soon  find  in  its  vicinity  nourishment 
for  growth. 

Method — Plants  of  the  sweet  clover  with  their  roots  may  be  brought  to 
the  schoolroom  for  study.  The  children  should  observe  sweet  clover  in 
the  field;  its  method  of  inflorescence,  and  the  insects  which  visit  it,  should 
be  noted. 

Observations — 1 . What  first  makes  you  aware  that  you  are  near  sweet 
clover?  On  what  kinds  of  soil,  and  in  what  localities,  does  sweet  clover 
abound  ? 

2.  Do  you  know  how  sweet  clover  growing  in  poor  soils  and  waste 
places  acts  as  a pioneer  for  other  plants? 

3.  Dig  up  a sweet  clover  plant,  and  see  how  far  its  stems  go  into  the 
soil? 

4.  How  high  does  the  plant  grow?  What  is  the  color  of  its  foliage? 

5.  Compare  one  of  the  leaves  with  the  leaf  of  a red  clover,  and  de- 
scribe the  likeness  and  the  difference.  Note  especially  the  edges  of  the 
upper  and  the  lower  leaves,  and  also  the  stipules. 

6.  Describe  the  way  the  sweet  clover  blossoms.  Do  the  lower  or 
upper  flowers  open  first  ? How  does  the  flower  stem  look  before  it  begins 
to  blossom  ? What  happens  to  it  after  the  blossoming  begins  ? How  long 
will  it  continue  to  blossom? 

7 . Take  a blossom  and  compare  it  with  that  of  a sweet  pea.  Can  you 
see  the  banner?  The  wings?  The  keel?  Can  you  see  if  the  stamens  are 
united  into  two  sets?  Can  you  see  the  pistil?  Note  the  shape  of  the 
calyx. 

8.  How  many  flowers  are  in  blossom  at  a time  ? Does  it  make  a mass 
of  white  to  attract  insects?  In  what  other  way  does  it  attract  insects? 
What  insects  do  you  find  visiting  it? 

9 . How  do  the  ripened  pods  look  ? 


“ The  blooming  wilds  His  gardens  are;  some  cheering 
Earth's  ugliest  waste  has  felt  that  flowers  bequeath, 

And  all  the  winds  o'er  summer  hills  careering 
Sound  softer  for  the  sweetness  that  they  breathe.'*

THE  WHITE  CLOVER 
Teacher's  Story 

sweet  clover  should  be  studied  first,  for  after 
making  this  study  it  is  easier  to  understand  the 
1 blossoming  of  the  white  and  the  red  clover.  In 

Sj^.f  I Uv  \ the  sweet  clovers,  the  flowers  are  strung  along  the 
i i Bl  I I stalk  but  in  the  red,  the  white,  and  many  others,  it 

\ \ I \j  is  as  if  the  blossom  stalk  were  telescoped,  so  that 

i.  the  flowers  are  all  in  one  bunch , the  tip  of  the  stalk 
making  the  center  of  the  clover  head.  We  use  the 
white  clover  in  our  lawns  because  of  a peculiarity  of  its  stem, 
which,  instead  of  standing  erect,  lies  flat  on  the  ground,  send- 
ing leaves  and  blossoms  upward  and  thus  making  a thick  carpet  over  the 
ground.  The  leaves  are  very  pretty;  and  although  they  grow  upon  the 
stems  alternately,  they  always  manage  to  twist  around  so  as  to  lift  their 
three  leaflets  upward  to  the  light.  The  three  leaflets  are  nearly  equal  in 
size,  with  fine,  even  veins  and  toothed  edges;  and  each  has  upon  it,  near 
the  middle  a pale,  angular  spot.  The  white  clover,  in  common  with  other 
clovers,  has  the  pretty  habit  of  going  to  sleep  at  night.  Botanists  may 
object  to  this  human  term,  but  the  great  Linnaeus  first  called  it  sleep,  and 
we  may  be  permitted  to  follow  his  example.  Certainly  the  way  the  clover 
leaves  fold  at  the  middle,  the  three  drawing  near  each  other,  looks  like 
going  to  sleep,  and  is  one  of  the  things  which  even  the  little  child  will 
enjoy  observing. 

The  clover  head  is  made  up  of  many  little  flowers;  each  one  has  a 
tubular  calyx  with  five  delicate  points  and  a little  stem  to  hold  it  up  into 
the  world.  In  shape,  the  corolla  is  much  like  that  of  the  sweet  pea,  and 
each  secretes  nectar  at  its  base.  The  outside  blossoms  open  first ; and  as 
soon  as  open,  the  honey  bees,  which  eagerly  visit  white  clover  wherever  it 
is  growing,  begin  at  once  their  work  of  gathering  nectar  and  carrying 
pollen ; as  soon  as  the  florets  are  pollenated  they  wither  and  droop  below 
the  flower-head. 

“Where  I made  One,  turn  down  an  empty  Glass.” 

Sings  old  Omar,  and  I always  think  of  it  when  I see  the  turned-down 
florets  of  the  white-clover  blossom.  But  in  this  case  the  glass  is  not 
empty,  but  holds  the  maturing  seed.  This  habit  of  the  white  clover 
flowers  saves  the  bees  much  time,  since  only  those  which  need  pollenating 
are  lifted  upward  to  receive  their  visits.  The  length  of  time  the  little 
clover  head  requires  for  the  maturing  of  its  blossoms  depends  much  upon 
the  weather  and  upon  the  insect  visitors. 

White  clover  honey  is  in  the  opinion  of  many  the  most  delicious  honey 
made  from  any  flowers  except,  perhaps,  from  orange  blossoms.  So 
valuable  is  the  white  clover  as  a honey  plant,  that  apiarists  often  grow 
acres  of  it  for  their  bees. 

LESSON  CLXVIII 
The  White  Clover 

Leading  thought — The  white  clover  has  creeping  stems.  Its  flowers 
depend  upon  the  bees  for  their  pollination,  and  the  bees  depend  upon  the 
white  clover  blossoms  for  honey .

Method — The  plant  may  be  brought  into  the  schoolroom  while  in  blos- 
som, and  its  form  be  studied  there.  Observations  as  to  the  fertilization  of 
the  flowers  should  be  made  out-of-doors. 

Observations — 1.  Where  does  the  white  clover  grow?  Why  is  it  so 
valuable  in  lawns? 

2.  Note  carefully  the  clover  leaf,  the  shape  of  the  three  leaflets,  stems, 
and  edges.  Is  part  of  the  leaflet  lighter  colored  than  the  rest?  If  so, 
describe  the  shape.  Are  the  leaflets  unequal  or  equal  in  size  ? Does  each 
leaf  come  directly  from  the  root?  Are  they  alternately  arranged ? Why 
do  they  seem  to  come  from  the  upper  side  of  the  stem? 

3.  Note  the  behavior  of  the  clover  leaves  at  night.  How  do  the  two 
'side  leaflets  act ? The  central  leaflet  ? Do  you  think  that  this  is  because 
the  plant  is  sleepy  ? 

i 4.  Take  a white  fclover  head,  and  note  that  it  is  made  up  of  many 
[little  flowers.  How  many?  Study  one  of  the  little  flowers  with  a lens. 
Can  you  see  its  calyx?  Its  petals?  Its  stem  ? In  what  way  is  it  similar 
to  the  blossom  of  the  sweet  pea? 

5.  Take  a head  of  white  clover  which  has  not  yet  blossomed.  Tie  a 

string  about  its  stem  so  that  you  may  be  sure  you  are  observing  the  same 
flower  and  make  the  following  observations  during  several  days : Which 

blossoms  begin  to  open  first — those  outside  or  inside?  How  many  buds 
open  each  day?  What  happens  to  the  blossoms  as  they  fade?  Of  what 
use  is  this  to  the  plant  ? How  many  days  pass  from  the  time  the  flowers 
begin  to  blossom  until  the  last  flower  at  the  center  opens? 

6.  What  insects  do  you  see  working  on  the  white  clover  blossoms? 
How  does  the  bee  act  when  collecting  nectar?  Can  you  see  where  she 
thrusts  her  tongue  ? What  does  the  bee  do  for  the  clover  blossom  ? What 
sort  of  honey  does  the  white  clover  give  to  the  bee  ? 

7.  Tie  little  bags  of  cheesecloth  over  two  or  three  heads  of  white 
clover  and  see  if  they  produce  any  seed.

THE  MAIZE,  OR  INDIAN  CORN 


Teacher's  Story 

“Hail!  Ha-wen-ni-yu!  Listen  with  open  ears  to  the  words  of  thy  people.  Continue 
to  listen.  We  thank  our  mother  earth  which  sustains  us.  We  thank  the  winds  which  have 
banished  disease.  We  thank  He-no  for  rain.  We  thank  the  moon  and  stars  which  give  us 
light  when  the  sun  has  gone  to  rest.  We  thank  the  sun  for  warmth  and  light  by  day.  Keep 
us  from  evil  ways  that  the  sun  may  never  hide  his  face  from  us  for  shame  and  leave  us  in 
darkness.  We  thank  thee  that  thou  hast  made  our  corn  to  grow.  Thou  art  our  creator  and 
our  good  ruler,  thou  canst  do  no  evil.  Everything  thou  doest  is  for  our  happiness.” 


HUS  prayed  the  Iroquois  Indians  when 
the  com  had  ripened  on  the  hills  and 
valleys  of  New  York  State  long  before 
it  was  a state,  and  even  before  Columbus  had 
turned  his  ambitious  prowrs  westward  in  quest  of 
the  Indies.  Had  he  found  the  Indies  with  their 
wealth  of  fabrics  and  spices,  he  would  have 
found  there  nothing  so  valuable  to  the  world  as 
has  proved  this  golden  treasure  of  ripened  com. 

The  origin  of  Indian  com,  or  maize,  is  shrouded 
in  mystery.  There  is  a plant  which  grows  on  the 
table-lands  of  Mexico,  which  is  possibly  the 
original  species ; but  so  long  had  maize  been  cultivated  by  the  American 
Indians  that  it  was  thoroughly  domesticated  when  America  was  first

discovered.  In  those  early  days  of  American  colonization,  it  is  doubtful, 
says  Professor  John  Fiske,  if  oui  forefathers  could  have  remained  here  had 
it  not  been  for  Indian  com.  No  plowing,  nor  even  clearing,  was  necessary 
for  the  successful  raising  of  this  grain.  The  trees  were  girdled,  thus  kill- 
ing their  tops  to  let  in  the  sunlight , the  rich  earth  was  scratched  a little 
with  a primitive  tool,  and  the  seed  put  in  and  covered;  and  the  plants 
that  grew  therefrom  took  care  of  therpselves.  It  the  pioneers  had  been 
obliged  to  depend  alone  upon  the  wheat  and  rye  of  Europe,  which  only 
grows  under  good  tilllage,  they  might  have  starved  before  they  gained  a 
foothold  on  our  forest-covered  shores. 


The  Corn  Plant 


In  studying  the  maize  it  is  well  to  keep  in  mind  that  a heavy  wind  is  its 
worst  enemy;  such  a wind  will  lay  it  low,  and  from  such  an  injury  it  is 
difficult  for  the  corn  to  recover  and  perfect  its  seed.  Thus,  the  mechanism 
of  the  corn-stalk  and  leat  is 
adapted  for  prevention  of  this 
disaster.  The  corn-stalk  is,  prac- 
tically, a strong  cylinder  with  a 
pithy  center;  the  fibres  of  the 
stalks  are  very  strong,  and  at 
short  intervals  the  stalk  is 
strengthened  by  hard  nodes,  or 
joints,  it  the  whole  stalk  were  as 
hard  as  the  nodes,  it  would  be 
inelastic  and  break  instead  of 
bend;  as  it  is,  the  stalk  is  very 
elastic  and  will  bend  far  over 
before  it  breaks.  The  nodes  are 
nearer  each  other  at  the  bottom, 
thus  giving  strength  to  the  base; 
they  are  farther  apart  at  the  top, 
where  the  wind  strikes,  and  where 
the  bending  and  bowing  of  the 
stalk  is  necessary. 

The  leaf  comes  off  at  a node 
and  clasps  the  stalk  for  a con- 
siderable distance,  thus  making  it 
stronger,  especially  toward  the 
base.  Just  where  the  leaf  starts 
away  from  the  stem  there  is  a 
little  growth  called  a rain-guard; 
if  water  should  seep  between  the 
stalk  and  the  clasping  leaf,  it 
would  afford  harbor  for  destruc- 
tive fungi.  The  structure  of  the 
com  leaf  is  especially  adapted  to 
escape  injury  from  the  wind ; the 
strong  veins  are  parallel  with  a 
strong  but  flexible  midrib  at  the 
center;  often,  after  the  wind  has 

whipped  the  leaves  severely,  only  stalk  of  corn  with  car  and  tassel. 


66  2 


Handbook  of  Nature-Study 


the  tips  are  split  and  injured.  The  edges  of  the  corn  leaf  are  ruffled 
and,  where  the  leaf  leaves  the  stalk,  there  is  a wide  fold  in  the 
edge  at  either  side;  this  arrangement  gives  play  for  a sidewise 
movement  without  breaking  the  leaf  margins.  The  leaf  is  thus 
protected  from  the  wind,  whether  it  is  struck  from  above  or  hori- 
zontally. The  true  roots  of  the  com  plant  go  quite  deep  into 
the  soil,  but  are  hardly  adequate  to  the  holding  of  such  a tall, 

slender  stalk  upright 
in  a wind  storm; 
therefore,  all  about 
the  base  of  the  plant 
are  brace-roots,  which 
serve  to  hold  the  stalk 
erect — like  the  stay- 
ropes  about  a flagpole. 

The  Ear  of  Corn 
The  ears  of  corn 
are  borne  at  the  joints 
or  nodes;  and  the 
stalk,  where  the  ear 
presses  against  it,  is 
hollowed  out  so  as  to 
hold  it  snugly;  this  is 
very  suggestive  of  a 
mother  holding  a baby 
in  her  arms.  In  the 
following  ways,  the 
husks  show  plainly 
that  they  are  modified 
leaves : The  hu  sk  has 

the  same  structure  as 
the  leaf,  having  paral- 
lel veins;  it  comes  off 

the  stem  like  a leaf; 

The  pollen-bearing  flowers  of  corn.  ^ is  °^en  green,  and 

therefore  does  the 

work  of  a leaf;  it  changes  to  leaf  .shape  at  the  tip  of  the  ear, 

thus  showing  that  the  husk  is  really  that  part  of  the  leaf  which 

usually  clasps  the  stem.  If  a husk  tipped  with  a leaf  is  examined, 
the  rain -guard  will  be  found  at  the  place  where  the  two  join. 
As  a matter  of  fact,  the  ear  of  com  is  on  a branch  stalk  which  has  been 
very  much  shortened,  so  that  the  nodes  are  very  close  together,  and  there- 
fore the  leaves  come  off  close  together.  By  stripping  the  husks  back  one 
by  one,  the  change  from  the  outside,  stiff,  green  leaf  structure  to  the 
inner  delicate,  papery  wrapping  for  the  seed,  may  be  seen  in  all  its  stages. 
This  is  a beautiful  lesson  in  showing  how  the  maize  protects  its  seed,  and  the 
husk  may  well  be  compared  to  the  clothing  of  a baby.  The  pistillate 
flowers  of  the  com,  which  finally  develop  into  the  kernels,  grow  in  pairs 
alongthe  sides  of  the  end  portion  of  the  shortened  stalk,  which  is  what  we 
call  the  “cob.”  Therefore,  the  ear  will  show  an  even  number  of  rows,  and 


Cultivated-Plant  Study 


663 


the  cob  shows  distinctly  that  the  rows  are  paired. 
The  corn-silk  is  the  style  of  the  pistillate  flowers ; and 
therefore,  in  order  to  secure  pollen,  it  must  extend 
from  the  ovule,  which  later  develops  into  a kernel, 
to  the  tip  of  the  ear,  where  it  protrudes  from  the  end 
of  the  husk.  A computation  of  the  number  of 
kernels  in  a row  and  on  the  ear  makes  a very  good 
arithmetic  lesson  for  the  primary  pupils,  especially 
as  the  kernels  occur  in  pairs. 

The  Growth  of  the  Corn 


The  tip  of  the  corn- silk 
showing  the  stigma;  j. 
The  pistillate  flower, 
which  will  develop  into 
the  kernel. 


If  we  cut  a kernel  of  com  crosswise  we  can  see,  near  the  point  where  it 
joins  the  cob,  the  little  plant  and  the  root.  Com  should  be  germinated 
between  wet  blotters,  in  a seed-testing  experiment,  before  observations 
are  made  on  the  growing  com  of  the  fields.  When  the  com  first  appears, 
the  com  leaves  are  in  a pointed  roll  which  pierces  the  soil.  Soon  they 
spread  apart,  but  it  may  be  some  time  before  the  corn-stalk  proper 
appears.  Then  it  stretches  up  rapidly,  and  very  soon  will  be  tipped  with 
beautiful  pale  brown  tassels.  These  tassels  merit  careful  study  for  they 
are  the  staminate  flowers.  Each  floret  has  two  anthers  hanging  down 
from  it,  and  each  half  of  each  anther  is  a little  bag  of  pollen-grains ; and  in 
order  that  they  shall  be  shaken  down  upon  the  waiting  corn-silk  below, 
the  bottom  of  each  bag  opens  wide  when  the  pollen  is  ripe.  The  com-silk, 
at  this  stage,  is  branched  at  the  tip  and  clothed  with  fine  hairs,  so  that  it 
may  catch  a grain  of  the  precious  pollen.  Then  occurs  one  of  the  most 
wonderful  pollen  stories  in  all  nature,  for  the  pollen -tube  must  push  down 
through  the  center  of  the  com-silk  for  its  whole  length,  in  order  to  reach 
the  waiting  ovule  and  thus  enable  it  to  become  a kernel  of  corn.  These 

young,  unfertilized  kernels  are  pretty 
objects,  looking  like  seed-pearls,  each 
wrapped  in  furry  bracts.  If  the  silk  from 
one  of  these  young  flowers  does  not 
receive  its  grain  of  pollen,  then  the  kernel 
will  not  develop  and  the  ear  will  be  im- 
perfect. On  the  other  hand  if  the  pollen 
from  another  variety  of  com  falls  upon 
the  waiting  stigmas  of  the  silk,  we  shall 
find  the  ear  will  have  upon  it  a mixture 
of  the  two  varieties . This  is  best  exempli- 
fied when  we  have  the  black  and  white 
varieties  of  sweet  corn  growing  near  each 
other. 

One  reason  why  com  is  such  a valu- 
able plant  to  us  is  that  its  growth  is  so 
rapid.  It  is  usually  not  planted  until 
late  spring,  yet,  with  some  varieties,  by 
September  the  stalks  are  twenty  feet 
high.  The  secret  of  this  is  that  the  com, 
unlike  many  other  plants,  has  many 
points  of  growth.  While  young,  the 
lower  part  of  the  stalk  lying  between 
every  two  nodes  is  a growing  center 


664 


Handbook  of  Nature-Study 


and  the  tip  of  the  stalk  also  grows;  in  most  plants,  the  tip  of  the  stems 
is  the  only  center  of  growth.  The  first  two  experiments  suggested  will 
demonstrate  this.  When  blown  down  by  the  wind,  the  corn  has  a wonder- 
ful way  of  lifting  itself,  by  inserting  growing  wedges  in  the  lower  sides  of 
the  nodes.  A corn-stalk  blown  down  by  the  wind  will  often  show  this 
wedge-shape  at  every  joint,  and  the  result  will  be  an  upward  curve 
of  the  whole  stalk.  Of  course,  this  cannot  be  seen  unless  the  stalk  is 
cut  lengthwise  through  the  center.  Experiment  3 is  suggested  to 
demonstrate  this. 

During  drought  the  corn  leaves  check  the  transpiration  of  water  by 
rolling  together  lengthwise  in  tubes,  thus  offering  less  surface  to  the  sun 
and  air.  The  farmer  calls  this  the  crtrling  of  the  corn,  and  it  is  always  a 
sign  of  lack  of  moisture.  If  a corn  plant  with  leaves  thus  curled,  be  given 
plenty  of  water,  the  leaves  will  soon  straighten  out  again  into  their  normal 
shape.

Corn  in  the  shock. 


LESSON  CLXIX 
The  Maize 

Leading  thought — The  Indian  corn,  or  maize,  is  a plant  of  much  beauty 
and  dignity.  It  has  wonderful  adaptations  for  the  development  of  its 
seed  and  for  resisting  its  arch-enemy,  the  wind. 

Method — The  study  may  begin  in  spring  when  the  com  is  planted, 
giving  the  pupils  the  outline  for  observations  to  be  filled  out  in  their  note- 


Cultivated-Plant  Study

books  during  the  summer,  when  they  have  opportunities  for  observing  the 
plant;  or.it  may  be  studied  in  the  autumn  as  a matured  plant.  It  may 
be  studied  in  the  school  room  or  in  the  field,  or  both. 

Observations  on  the  corn  plant — i.  Describe  the  central  stem.  How 
many  joints,  or  nodes,  has  it  ? Of  what  use  to  the  plant  are  these  nodes  ? 
Are  the  joints  nearer  each  other  at  the  bottom  or  the  top  of  the  plant  ? 

2 . Where  do  the  leaves  come  off  the  stem  ? Describe  the  relation  of 
the  bases  of  the  leaves  to  the  stem.  Of  what  use  is  this  to  the  plant  ? 

3.  Note  the  little  growth  on  the  leaf  where  it  leaves  the  stalk. 
Describe  how  this  prevents  the  rain  from  seeping  down  between  the  stalk 
and  the  clasping  leaf.  What  danger  would  there  be  to  the  plant  if  the 
water  could  get  into  this  narrow  space? 

4.  What  is  the  shape  of  the  leaf?  Describe  the  veins.  Does  the  leaf 
tear  easily  across?  Does  it  tear  easily  lengthwise?  Of  what  use  to  the 
leaf  is  this  condition  ? 

5.  Are  the  edges  of  the  corn  leaf  straight  or  ruffled  ? How  does  this 
ruffled  edge  permit  the  leaf  to  turn  without  breaking?  Describe  at 
length  the  benefit  the  com  plant  derives  from  having  leaves  which  cannot 
be  broken  across  and  that  can  bend  readily  sidewise  as  well  as  up  and  down . 

6.  Describe  the  roots  of  the  com  plant.  Describe  the  brace-roots. 
Explain  their  use. 

7.  Describe  all  the  ways  in  which  the  corn  plant  is  strengthened 
against  its  enemy,  the  wind. 

Observation  on  the  ear  of  corn — 8.  Where  on  the  corn  plant  are  the  ears 
borne  ? Are  two  ears  borne  on  the  same  side  of  the  stalk  ? Remove  an 
ear,  and  see  how  the  stalk  is  changed  to  give  it  room. 

9.  Where  do  the  ears  come  off  the  stalk  in  relation  to  the  leaves? 

10.  Examine  the  outside  husks,  and  compare  them  with  the  green 
leaves.  What  is  there  to  suggest  that  the  corn-husk  is  a leaf  changed  to 
protect  the  seed  ? Do  you  think  that  the  husk  represents  that  portion  of 
the  leaf  which  clasps  the  stalk?  Why?  Describe  how  the  inner  husk 
differs  from  the  outer  in  color  and  texture.  Describe  how  this  is  a special 
protection  to  the  growing  kernels. 

1 1 . After  carefully  removing  the  husk,  examine  the  silk  and  see  if 
there  is  a thread  for  ever}'"  kernel.  Is  there  an  equal  amount  of  silk  lying 
between  every  two  rows?  Do  you  know  what  part  of  the  corn  flower  is 
the  comsilk?  What  part  is  the  kernel? 

12.  How  many  rows  of  kernels  are  thereon  an  ear?  How  many  ker- 
nels in  a row?  How  many  on  the  whole  ear?  Do  any  of  the  rows  disap- 
pear toward  the  tip  of  the  ear?  If  so,  do  they  disappear  in  pairs?  Do 
you  know  why  ? Are  the  kernels  on  the  tip  of  the  ear  and  near  the  base  as 
perfect  as  those  along  the  middle?  Do  you  know  whether  they  will 
germinate  as  quickly  and  vigorously  as  the  middle  ones? 

13.  Study  a cob  with  no  corn  on  it  and  note  if  the  rows  of  kernel- 
sockets  are  in  distinct  pairs.  This  will,  perhaps  show  best  if  you  break 
the  cob  across. 

14.  Break  an  ear  of  com  in  two,  and  sketch  the  broken  end  showing 
the  relation  of  the  cob  to  the  kernels. 

15.  Are  there  any  places  on  the  ear  you  are  studjdng.  where  the 
kernels  did  not  grow  or  are  blasted?  What  happened  to  cause  this? 

16.  Describe  the  requisites  for  a perfect  ear  of  seed-com.  Why  should 
the  plant  from  which  the  seed-ear  is  taken  be  vigorous  and  perfect?.

Observations  on  the  growth  of  corn — Work  for  the  Summer  Vacation — 

17.  How  does  the  com  look  when  it  first  comes  up?  How  many 
leaves  are  there  in  the  pointed  roll  which  first  appears  above  the  ground? 
How  long  before  the  central  stalk  appears? 

18.  When  do  the  tassels  first  appear?  What  kind  of  flowers  are  the 
com  tassels  ? Describe  the  anthers . How  many  on  each  flower  ? Where 
do  the  anthers  open  to  discharge  their  pollen? 

19.  How  large  are  the  ears  when  the  pollen  is  being  shed?  Study  an 
ear  of  corn  at  this  period.  Note  that  the  kernel  is  the  ovule,  the  silk  is 
attached  to  it  and  is  the  long  style  extending  out  beyond  the  husks.  Note 
that  the  tip,  or  stigma  is  branched. 

20.  What  carries  the  pollen  for  the  corn  plant?  If  you  have  rows  of 
popcorn  and  sweet  com  or  of  sweet  corn  and  field  corn  next  to  each  other 
why  is  it  that  the  ears  will  show  a mixture  of  both  kinds? 

EXPERIMENT  I 

Compare  the  growth  of  the  com  plant  with  that  of  the  pigweed. 
When  the  corn-stalk  first  appears  above  ground,  tie  two  strings  upon  it, 
one  just  above  a joint  and  one  below  it.  Tie  two  strings  the  same  dis- 
tance apart  on  the  stem  of  a pigweed.  Measure  carefully  the  distance 
between  these  two  strings  on  the  two  plants.  Two  weeks  later  measure 
the  distance  between  the  strings  again.  What  is  the  result  ? 

EXPERIMENT  2 

Measure  the  distance  between  two  of  the  nodes  or  joints  near  the  tip  of 
a certain  corn-stalk.  Two  weeks  later  measure  this  distance  again  and 
compare  the  two . 

EXPERIMENT  3 

When  a stalk  of  corn  is  still  green  in  August,  bend  it  down  and  place  a

to  an  erect  attitude  after  two  or  three  weeks.  Cut  lengthwise  across  one 
of  the  nodes,  beyond  the  point  held  down  by  the  stick,  and  see  the  wedge-

THE  COTTON  PLANT 
Teacher's  Story 

There  are  some  plants  which  have  made  great  chapters  in  the  histories 
of  nations,  and  cotton  is  one  of  them.  The  fibre  of  cotton  was  used  for 
making  clothing  so  long  ago,  that  its  discovery  is  shrouded  in  the  myths 
of  prehistoric  times.  But  we  believe  it  first  came  into  use  in  India,  for  in 
this  land  we  find  certain  laws  concerning  cotton  which  were  codified 
8co  B<  C.;  and  allusions  to  the  fine,  white  raiment  of  the  peoples  of  India 
are  frequent  in  ancient  history.  Cotton  was  introduced  into  Egypt  from 
India  at  an  early  date:  it  was  in  common  use  there  150  B.  C,  But  not

until  our  Civil  War  laid  fallow  the  cotton  fields  of  the  United  States, 
did  Egypt  realize  the  value  of  its  crop;  and  although  much  money  was 
lost  there  in  agricultural  speculation  after  our  own  product  was  again  put 
on  the  market,  yet  cotton  has  remained  since  that  time  one  of  Egypt’s 
most  valuable  exports. 

When  Columbus  discovered  America  he  found  cotton  growing  in  the 
West  Indies,  and  the  chief  articles  of  clothing  of  the  native  Mexicans  were 
made  of  cotton.  Cloths  of  cotton  were  also  found  in  ancient  tombs  of 


The  cotton  in  blossom. 


Peru,  proving  it  was  used  there  long  before  the  white  man  set  his  foot 
upon  those  shores.  When  Magellan  made  his  famous  voyage  around  the 
world  in  1500,  he  found  the  cotton  fibre  in  use  in  Brazil. 

It  is  a strange  fact  that  the  only  region  of  the  world  between  the 
parallels  of  40°  north  and  40°  south  latitude,  where  cotton  did  not  grow  as 
a native  or  cultivated  plant  when  America  was  discovered,  was  the  region 
01  our  Gulf  States,  which  now  produces  more  cotton  than  any  other. 
The  first  mention  of  cotton  as  a crop  in  the  American  colonies  is  in  the 
report  published  in  1666.  At  the  time  of  the  Revolutionary  War  the 
cotton  industry  was  thoroughly  established.  It  is  one  of  the  significant 
facts  of  history  that  the  invention  of  the  cotton  gin  by  Eli  Whitney  in 
1793,  which  revolutionized  the  cotton  industry  and  brought  it  to  a much 


568 


Handbook  of  Nature-Study 


more  profitable  basis,  wrought  great  evil  to  the  United  States,  since  it 
revived  the  profits  of  slave-holding.  The  institution  of  slavery  was  sink- 
ing out  of  sight  by  its  own  weight;  Washington  showed  that  it  was  the 
most  expensive  way  to  work  land,  and  Jefferson  failed  to  liberate  his  own 
slaves  simply  because  he  believed  that  liberty  would  come  to  all  slaves 
inevitably,  since  slave-holding  was  such  an  expense  to  the  plantation 
owners.  But  the  cotton  gin,  which  removed  the  seeds  rapidly — theretofore 
done  by  slow  and  laborious  hand  process — suddenly  made  the  raising  of 
cotton  so  profitable  that  slaves  were  again  employed  in  its  production 
with  great  financial  benefits.  And  thus  it  came  about  that  the  cotton 
plant  innocently  wielded  a great  influence  in  the  political,  as  well  as  the 
industrial  life  of  our  country. 

The  cotton  plant  has  a taproot,  with  branches  which  go  deep  into  the 
soil.  The  stem  is  nearly  cylindrical,  the  branches  often  spreading  and 
sometimes  irregular;  the  bark  is  dark  and  reddish;  the  wood  is  white. 
In  Egypt,  and  probably  in  other  arid  countries,  the  stalks  are  gathered 
for  fuel  in  winter. 

The  leaves  are  alternate,  with  long  petioles.  The  upper  leaves  are 
deeply  cut,  some  having  five,  some  seven,  some  three,  and  some  even  nine 
lobes;  strong  veins  extend  from  the  petiole  along  the  center  of  each  lobe; 
the  leaves  near  the  ground  may  not  be  lobed  at  a-11.  Where  the  petiole 
joins  the  stem,  there  is  a pair  of  long,  slender,  pointed  stipules,  but  they 
often  fall  off  early.  A strange  characteristic  of  the  cotton  leaves  is  tha\. 
they  bear  nectar-glands;  these  may  be  seen  on  the  under  side  and  along 
the  main  ribs  of  the  leaf ; they  appear  as  little  pits  in  the  rib ; some  leaves 
may  have  none,  while  others  may  have  from  one  to  five.  It  has  been 
thought  that  perhaps  these  glands  might  attract  bees,  wasps  or  ants, 
which  would  attack  the  caterpillars  eating  the  leaves,  but  this  has  not 
been  proved.  However,  many  friendly  insects  get  their  nectar  at  these 
leaf-wells,  and  here  is  an  opportunity  for  some  young  naturalist  of  the 
South  to  investigate  this  matter  and  discover  what  insects  come  to  these 
glands  at  all  times  of  day  and  what  they  do. 

The  flower  bud  is  partially  hidden  beneath  the  clasping  bracts  of  the 
involucre.  These  bracts  are  three  or  four  in  number,  and  they  have  the 
edges  so  deeply  lobed  that  they  seem  branched.  By  pushing  back  the 
bracts  we  can  find  the  calyx,  which  is  a shallow  cup  with  five  shallow 
notches  in  its  rim.  The  petals  are  rolled  in  the  bud  like  a shut  umbrella. 
The  open  flower  has  five  broadly  spreading  petals;  when  the  bud  first 
opens  in  the  morning,  the  petals  are  whitish  or  pale  yellow  with  a purplish 
spot  at  the  base,  by  noon  they  are  pale  pink,  by  the  next  day  they  are  a 
deep  purplish  red  and  they  fall  at  the  end  of  the  second  day.  There  are 
nectar-glands  also  in  the  flower  at  the  base  of  the  calyx,  and  the  insects 
are  obliged  to  thrust  their  tongues  between  the  bases  of  the  petals  to  reach 
the  nectar,  only  long-tonguedbees,  moths  and  butterflies  are  able  to  attain 
it. 

There  are  many  stamens  which  have  their  filaments  united  in  a tube 
extending  up  into  the  middle  of  the  flower  and  enlarging  a little  at  the  tip; 
below  the  enlarged  base  of  this  tube  is  the  ovary  which  later  develops  into 
the  cotton-boll;  within  the  stamen-tube  extends  the  long  style,  and  from 
its  tip  are  thrust  out  from  three  to  five  stigmas  like  little  pennants  from 
the  top  of  a chimney;  and  sometimes  they  are  more  or  less  twisted  to- 
gether. The  young  boll  is  covered  and  protected  by  the  fringed  bracts.

which  cover  the  bud  and  remain  attached  to  the  ripened  boll  The 
calyx,  looking  like  a little  saucer,  also  remains  at  the  base  of  the  bolb 
The  boll  soon  assumes  an  elongated,  oval  shape,  with  long,  pointed  tip, 
it  is  green  outside  and  covered  with  little  pits,  as  large  as  pin  points. 
There  are,  extending  back  from  the  pointed  tip,  three  to  five  creases  or 
sutures,  which  show  where  the  bell  will  open.  If  we  open  a nearly 
ripened  boll,  we  find  that  half  way  between  each  two  sutures  where  the 
boll  will  open,  there  is  a partition  extending  into  the  boll  dividing  it  into 
compartments.  These  are  really  carpels,  as  in  the  core  of  an  apple,  and 
their  leaf  origin  may  be  plainly  seen  in  the  venation.  The  seeds  are 
fastened  by  their  pointed  ends  along  each  side  of  the  central  edge  of  the 
partition,  from  which  they  break  away  very  easily.  The  number  of  seeds 
varies,  usually  two  or  three  along  each  side;  the  young  seeds  are  wrapped 
in  the  young  cotton,  which  is  a stringy,  soft  white  mass.  The  cotton 
fibres  are  attached  to  the  covering  of  the  seed  around  the  blunt  end,  and

usually  the  pointed  end  is  bare.  When  the  boll  opens,  the  cotton  becomes 
very  fluffy  and  if  not  picked  will  blow  away;  for  this  cotton  fibre  is  a 
device  of  the  wild  cotton  for  disseminating  its  seeds  by  sending  them  off 
on  the  wings  of  the  wind.  Heavy  winds  at  the  cotton -picking  time,  are  a 
menace  to  the  crop  and  often  occasion  serious  loss. 

The  mechanism  of  the  opening  of  the  cotton -boll  is  very  interesting; 
along  the  central  edge  of  each  partition  and  extending  up  like  beaks  into 
the  point  of  the  boll,  is  a stiff  ridge,  about  the  basal  portion  of  which  the 
seeds  are  attached;  as  the  boll  becomes  dry,  this  ridged  margin  becomes 
as  stiff  as  wire  and  warps  outward;  at  the  same  time,  the  outside  of  the 
boll  is  shriveling.  This  action  tears  the  boll  apart  along  the  sutures  and 
exposes  the  seeds  with  their  fluffy  balloons  to  the  action  of  the  wind.  The 
ripe,  open,  empty  boll  is  worth  looking  at;  the  sections  are  wide  apart 
and  each  white,  delicate,  parchment-like  partition,  or  carpel,  has  its  wire 
edge  curved  back  gracefully.  The  outside  of  the  boll  is  brown  and 
shriveled,  but  inside  it  is  still  white  and  shows  that  it  had  a soft  lining  for 
its  “seed babies.” 

The  amount  of  the  cotton  crop  per  acre  varies  with  the  soil  and 
climate;  the  amount  that  can  be  picked  per  day  also  depends  upon  the 


6 70

cotton  as  well  as  the  picker.  Children  have  been  known  to  pick  ons 
hundred  pounds  per  day,  and  a first-class  picker  from  five  hundred  to  six 
hundred  pounds,  or  even  eight  hundred;  one  man  has  made  a record  of 
picking  sixty  pounds  in  an  hour.  Cotton  is  one  of  the  most  important 
crops  grown  in  America,  and  there  are  listed  more  than  one  hundred  and 
thirty  varieties  which  have  originated  in  our  country.

LESSON  CLXX 
Cotton 


Leading  thought — Cotton  has  had  a great  influence  upon  our  country 

politically  as  well  as  in- 
dustrially. Its  fibre  was 
used  by  the  ancients, 
and  it  is  to-day  one  of  the 
most  important  crops  in 
the  regions  where  it  is 
grown. 

Method — A cotton 
plant  with  blossoms  and 
ripe,  bolls  upon  it  may  be 
brought  into  the  school- 
room or  studied  in  the 
field.

5.  Look  at  the  lower  side  of  a leaf  and  find,  if  you  can,  a little  pit  on 
the  midrib  near  its  base.  How  many  of  these  pits  can  you  find  on  the 
veins  of  one  leaf?  What  is  the  fluid  in  these  pits?  Taste  it  and  see  if  it 
is  sweet.  Watch  carefully  a growing  plant  and  describe  what  insects  you

there  in  it?  Where  are  they  in  relation  to  the  openings?  Gently  push 
back  the  cotton  from  the  seeds  without  loosening  them,  and  describe  how 
the  seeds  are  connected  with  the  partitions.  Is  the  seed  attached  by  its 
pointed  or  blunt  end  ? 

12.  How  many  seeds  in  each  chamber  in  the  cotton  boll?  Whereon 
the  seed  does  the*cotton  grow?  How  does  the  cotton  blanket  wrap  about 
the  seed?  If  the  cotton  is  not  picked  what  happens  to  it ? Of  what  use 
to  the  wild  cotton  plant  are  seeds  covered  with  cotton  ? 

13.  What  makes  the  cotton-boll  open?  Describe  an  open  and  empty 
boll  outside  and  inside.

THE  STRAWBERRY 
Teacher's  Story 

Of  all  the  blossoms  that  clothe  our  open  fields,  one  of  the  prettiest  is 
that  of  the  wild  strawberry.  And  yet  so  influenced  is  man  by  his  stomach 
that  he  seldom  heeds  this  flower  except  as  a promise  of  a crop  of  straw- 
berries. It  is  comforting  to  know  that  the  flowers  of  the  field  “do  not 
care  a rap”  whether  man  notices  them  or  not;  insect  attentions  are  what 
they  covet,  and  they  are  surely  as  indifferent  to  our  indifference  as  it  is  to 
them. 

The  field  strawbeny’s  five  petals  are  little  cups  of  white  held  up 
protectingly  around  a central  treasure  of  anthers  and  pistils ; each  petal 
has  its  base  narrowed  into  a little  stem,  which  the  botanists  call  a claw. 
When  the  blossom  first  opens,  the  anthers  are  little,  flat,  vividly  lemon- 
yellow  discs,  each  disc  consisting  of  two  clamped  together  sternly  and 
determinedly  as  if  they  meant  never  to  open  and  yield  their  gold  dust. 
At  the  very  center  of  the  flower  is  a little,  greenish  yellow  cone,  which  if 
we  examine  with  a lens,  we  can  see  is  made  up  of  many  pistils  set  together, 
each  lifting  up  a little,  circular,  eager  stigma  high  as  ever  it  can  reach. 
Whether  all  the  stigmas  receive  pollen  or  not  determines  the  formation  of 
a good  strawberry. 

The  sepals  are  slender  and  pointed  and  seem  to  be  ten  in  number, 
every  other  one  being  smaller  and  shorter  than  its  neighbors ; but  the  five 
shorter  ones  are  not  sepals  but  are  bracts  below  the  calyx.  The  sepals 
unite  at  their  bases  so  that  the  strawberry  has  really  a lobed  calyx  instead 
of  separate  sepals.  The  blossom  stem  is  soft,  pinkish  and  silky  and  wilts 
easily.  There  are  several  blossoms  borne  upon  one  stem  and  the  central 
one  opens  first. 


Cultivated-Plant  Study

The  strawberry  leaf  is  beautiful ; each  of  its  three  leaflets  is  oval,  deeply 
toothed,  and  has  strong  regular  veins  extending  from  the  midrib  to  the 
tip  of  each  tooth.  I11  color  it  is  rich,  dark  green  and  turns  to  wine-color 
in  autumn.  It  has  a very 
pretty  way  of  coming  out 
of  its  hairy  bud  scales,  each 
leaflet  folded  lengthwise 
and  the  three  pressed  to- 
gether. Its  whole  appear- 
ance then,  is  infantile  in 
the  extreme,  it  is  so  soft 
and  helpless  looking.  But 
it  soon  opens  out  on  its 
pink,  downy  stem  and 
shows  the  world  how  beau- 
tiful a leaf  can  be. 

If  a comparison  of  the 
wild  and  cultivated  straw- 
berries is  practicable,  it 
makes  this  lesson  more  in- 
teresting. Much  tillage  an  d food  have  caused  the  cultivated  blossoms  to 
double,  and  they  may  often  have  seven  or  eight  petals.  And  while  the 
wild  flowers  are  usually  perfect,  many  cultivated  varieties  have  the  pollen 
and  pistils  borne  in  different  flowers,  and  they  depend  upon  the  bees  to 
carry  their  pollen.  The  blossom  stem  of  the  garden  strawberry  is  round, 
smooth  and  quite  strong,  holding  its  branching  panicle  of  flowers  erect, 
and  it  is  usually  shorter  than  the  leaf  stems  among  which  it  nestles.  The 
flowers  open  in  a series,  so  that  ripe  and  green  fruit,  flowers  and  buds  may 
often  be  found  on  the  same  stem.  As  the  strawberry  ripens,  the  petals 
and  stamens  wither  and  fall  away;  the  green  calyx  remains  as  the  hull, 
which  holds  in  its  cup  the  pyramid  of  pistils  which  swell  and  ripen  into  the 
juicy  fruit.  To  the  botanists  the  strawberry  is  not  a berry,  that  definition 
being  limited  to  fruits  having  a juicy  pulp  and  containing  many  seeds, 
like  the  currant  or  grape.  The  strawberry  is  a fleshy  fruit  bearing  its 
seed  in  shallow  pits  on  its  surface.  These  seeds  are  so  small  that  we  do 
not  notice  them  when  eating  the  fruit,  but  each  one  is  a tiny  nut,  almond- 
shaped,  and  containing  within  its  tough,  little  shell  a starchy  meat  to  sus- 
tain the  future  plant  which  may  grow  from  it.  It  is  by  planting  these 
seeds  that  growers  obtain  new  varieties. 

The  root  of  the  strawberry  is  fibrous  and  threadlike.  When  growers 
desire  plants  for  setting  new  strawberry  beds  they  are  careful  to  take  only 
such  as  have  light  colored  and  fresh-looking  roots.  On  old  plants  the 
roots  are  rather  black  and  woody  and  are  not  so  vigorous. 

The  stem  of  the  strawberry  is  partially  underground  and  so  short  as  to 
be  unnoticeable.  However,  the  leaves  grow  upon  it  alternately  one  above 
another,  so  that  the  crown  rises  as  it  grows.  The  base  of  each  leaf  has  a 
broad,  clasping  sheath  which  partly  encircles  the  plant  and  extends 
upward  in  a pair  of  earlike  stipules. 

The  runners  begin  to  grow  after  the  fruiting  season  has  closed;  they 
originate  from  the  upper  part  of  the  crown ; they  are  strong,  fibrous  and 
hairy  when  young.  Some  are  short  between  joints,  others  seem  to  reach 
far  out  as  if  seeking  for  the  best  location  before  striking  root;  a young

plant  wilt  often  have  several  leaves  before  putting  forth  roots.  Each 
runner  may  start  one  or  more  new  strawberry  plants.  After  the  young 
plant  has  root  growth  so  as  to  be  able  to  feed  itself,  the  runner  ceases  to 
carry  sap  from  the  main  stem  and  withers  to  a mere  dry  fiber.  The 
parent  plant  continues  to  live  and  bear  fruit,  for  the  strawberry  is  a per- 
ennial, but  the  later  crops  are  of  less  value.  Gardeners  usually  renew 
their  plots  each  year,  but  if  intending  to  harvest  a second  year’s  crop, 
they  cut  off  the  runners  as  they  form.

LESSON  CLXXI 
The  Strawberry 

Leading  thought — The  strawberry  plant  has  two  methods  of  perpet- 
uating itself,  one  by  the  seeds  which  are  grown  on  the  outside  of  the 
strawberry  fruits,  and  one  by  means  of  runners  which  start  new  plants 
wherever  they  find  place  to  take  root. 

Method — It  would  be  well  to  have  a strawberry  plant,  with  roots  and 
runners  attached,  for  an  observation  lesson  by  the  class.  Each  pupil 
should  have  a leaf,  including  the  clasping  stipules  and  sheath  at  its  base. 
Each  one  should  also  have  a strawberry  blossom  and  bud,  and  if  possible 
a green  or  ripe  fruit. 

Observations — i.  What  kind  of  root  has  the  strawberry?  What  is  its 
color? 

2.  How  are  the  leaves  of  the  strawberry  plant  arranged?  Describe 
the  base  of  the  leaf  and  the  way  it  is  attached  to  the  stem.  Has  each 
leaflet  a pedicel  or  stem  of  its  own?  How  many  leaflets  are  there? 
Sketch  a strawberry  leaf,  showing  the  edges  and  form  of  the  leaflets,  and

3.  From  what  part  of  the  plant  do  the  runners  spring?  When  do  the 
runners  begin  to  grow?  Does  the  runner  strike  root  before  forming  a new 
plant  or  does  the  little  plant  grow  on  the  runner  and  draw  sustenance 
from  the  parent  plant  ? 

4.  What  happens  to  the  runners  after  the  new  plants  have  become 
established?  Does  the  parent  plant  survive  or  die  after  it  sends  out 
many  runners? 

5.  Describe  the  strawberry  blossom.  How  many  parts  are  there  to 
the  hull  or  calyx  ? Can  you  see  that  five  of  these  are  set  below  the  other 
five? 

6.  How  many  petals  has  it?  Does  the  number  differ  in  different- 
flowers?  Has  the  wild  strawberry  as  many  petals  as  the  cultivated  ones? 

7.  Study  with  a lens  the  small  green  button  at  the  center  of  the 
flower.  This  is  made  up  of  pistils  so  closely  set  that  only  their  stigmas 
may  be  seen.  Do  you  find  this  button  of  pistils  in  the  same  blossom  with 
the  stamens  ? Does  the  wild  blossom  have  both  stamens  and  pistils  in  the 
same  flower? 

8.  Describe  the  stamens.  What  insects  carry  pollen  for  the  straw- 
berry plants  ? 

9.  Are  the  blossoms  arranged  in  clusters  ? Do  the  flowers  all  open  at 
the  same  time?  What  parts  of  the  blossom  fall  away  and  what  parts 
remain  when  the  fruit  begins  to  form? 

10.  Are  the  fruits  all  of  the  same  shape  and  color?  Is  the  pulp  of  the 
same  color  within  as  on  the  surface?  Has  the  fruit  an  outer  coat  or  skin? 
What  are  the  specks  on  its  surface? 

1 1 . How  many  kinds  of  wild  strawberries  do  you  know?  How  many 
kinds  of  cultivated  strawberries  do  you  know? 

12.  Describe  howyou  should  prepare,  plant  and  care  for  a strawberry 
bed. 


THE  PUMPKIN 
Teacher's  Story 

If  the  pumpkin  were  as  rare  as  some  orchids,  people  would  make  long 
pilgrimages  to  look  upon  so  magnificent  a plant.  Although  it  trails  along 
the  ground,  letting  Mother  Earth  help  it  support  its  gigantic  fruit,  yet 
there  is  no  sign  of  weakness  in  its  appearance ; the  vine  stem  is  strong, 
ridged,  spiny  and  purposeful.  And  the  spines  upon  it  are  surely  a protec- 
tion under  some  circumstances,  for  I remember  distinctly  when,  as 
children,  bare-footed  and  owning  the  world,  we  “played  Indian”  and 
found  our  ambush  in  the  long  rows  of  ripening  corn,  we  skipped  over  the 
pumpkin  vines,  knowing  well  the  punishment  they  inflicted  on  the  un- 
wary feet. 

From  the  hollow,  strongly  angled  stem  arise  in  majesty  the  pumpkin 
leaves,  of  variously  lobed  patterns,  but  all  formed  on  the  same  decorative 
plan.  The  pumpkin  leaf  is  as  worthy  of  the  sculptor’s  chisel  as  is  that  of 
the  classic  acanthus:  it  is  palmat-ely  veined,  having  from  three  to  five 
lobes,  and  its  broad  base  is  supported  for  a distance  on  each  side  of  the 
angled  petiole  by  the  two  basal  veins.  The  leaves  are  deep  green  above, 
paler  below  and  are  covered  on  both  sides  with  minute  bristles,  and  their 
edges  are  finely  toothed.  The  bristly,  angled  stem  which  lifts  it  aloft  is  a

quite  worthy  support  for  so  beautiful  a leaf.  And,  during  our  childhood, 
it  was  also  highly  esteemed  as  a trombone,  for  it  added  great  richness  of 
quality  to  our  orchestral  performances,  balancing  the  shrillness  of  the 
basswood  whistle  and  the  sharp  buzzing  of  the  dandelion-stem  pipe. 

Growing  from  a point  nearly  opposite  a leaf,  may  be  seen  the  pumpkin’s 
elaborate  tendril.  It  has  a stalk  like  that  of  the  leaf,  but  instead  of  the 
leaf  blade  it  seems  to  have  the  three  to  five  naked  ribs  curled  in  long,  small 
coils  very  even  and  exact.  Perhaps,  at  some  period  in  the  past,  the 
pumpkin  vines  lifted  themselves  by  clinging  to  trees,  as  do  the  gourd  vines 
of  to-day.  But  the  pumpkin  was  cultivated  in  fields  with  the  maize  by 
the  North  American  Indians,  long  before  the  Pilgrim  Fathers  came  to 
America,  to  make  its  fruit  into  pies.  Since  the  pumpkin  cannot  sustain 
itself  in  our  Northern  climate  without  the  help  of  man,  it  was  evidently  a 
native  of  a warmer  land;  and,  by  growing  for  so  long  a time  as  a com- 
panion of  the  corn,  it  has  learned  to  send  its  long  stems  out  for  many  feet, 
resting  entirely  upon  the  ground.  But,  like  a conservative,  elderly 
maiden  lady,  it  still  wears  corkscrew  curls  in  memory  of  a fashion,  long 
since  obsolete.  Occasionally,  we  see  the  pumpkin  vines  at  the  edge  of  the 
field  pushing  out  and  clambering  over  stone  piles,  and  often  attempting  to 
climb  the  rail  fences,  as  if  there  still  remained  within  them  the  old  instinct 
to  climb. 

But  though  its  foliage  is  beautiful,  the  glory  of  the  pumpkin  is  its 
vivid  yellow  blossom  and,  later,  its  orange  fruit.  When  the  blossom  first 
starts  on  its  career  as  a bud,  it  is  enfolded  in  a bristly,  ribbed  calyx  with 
five  stiff,  narrow  lobes,  which  close  up  protectingly  about  the  green,  cone- 
shaped  bud,  a rib  of  the  cone  appearing  between  each  two  lobes  of  the

calyx.  If  we  watch  one  of  these  buds  day  after  day,  we  find  that  the 
green  cone  changes  to  a yellow  color  and  a softer  texture  as  the  bud  un- 
folds, and  then  we  discover  that  it  is  the  corolla  itself;  however,  ihese  ribs 
which  extend  out  to  the  tip  of  the  corolla-lobes  remain  greenish  below, 
permanently.  The  expanding  of  the  flower  bud  is  a pretty  process;  each 
lobe,  supported  by  a strong  midrib,  spreads  out  into  a five-pointed  star, 
each  point  being 
very  sharp  and  an- 
gular because, 
folded  in  along 
these  edges  in  one 
of  the  prettiest  of 
Nature’s  hems,  is 
the  ruffled  margin 
"of the  flower.  Not 
until  the  sun  has 
shone  upon  the 
star  for  some  little 
time  of  a summer 
morning,  do  these 
tumed-in  margins 
open  out;  and,  late 
in  the  afternoon  or 
during  a .storm, 
they  fold  down 
again  neatly  before 
the  lobes  close  up;

in  escaping  she 
may,  willy-nilly, 
get  a night’s  lodg-

is  a double  one,  and 

we  had  best  begin  it  by  selecting  a flower  that  has  below  it  a little  green 
globe — the  ovary — which  will  later  develop  into  a pumpkin.  At  the 
heart  of  such  a flower  there  stand  three  stigmas,  that  look  like  liliputian 
boxing-gloves ; each  is  set  on  a stout,  postlike  style,  which  has  its  base  in  a 
great  nectar-cup,  the  edges  of  which  are  slightly  incurved  over  its  welling 
sweetness.  In  order  to  reach  this  nectar,  the  lady  bee  must  stand  on  her 
head  and  brush  her  pollen-dusted  side  against  the  greedy  stigmas.  Pn> 
fessor  Duggar  has  noted  that  in  dry  weather  the  margins  of  this  nectar-cup 
contract  noticeably,  and  that  in  wet  weather  the  stigmas  close,  down  as  if 
the  boxing-gloves  were  on  closed  fists. 

The  other  half  of  the  pumpkin-blossom  story  is  to  be  found  in  the 
flowers  which  have  no  green  globes  below  them,  for  these  produce  the 
pollen.  Such  a flower  has  at  its  center  a graceful  pedestal  with  a broad

base  and  a slender  stem,  which  upholds  a curiously  folded,  elongate  knob, 
that  looks  like  some  ancient  or  primitive  jewel  wrought  in  gold.  The 
corrugations  on  its  surface  are  the  anther-cells,  which  are  curiously  joined 
and  curved  around  a central  oblong  support ; by  cutting  one  across,  we 
can  see  plainly  the  central  core,  bordered  by  cells  filled  with  pollen.  But 
where  is  the  nectar  well  in  the  smooth  cup  of  this  flower?  Some  have

maintained  that  the  bees  visit  this  flower  for  the  sake  of  the  pollen,  but  I 
am  convinced  that  this  is  not  all  of  the  story.  In  the  base  of  the  pedestal 
which  supports  the  anther  knob  there  appear,  after  a time,  three  incon- 
spicuous openings;  and  if  we  watch  a bee,  we  shall  see  that  she  knows 
these  openings  are  there  and  eagerly  thrusts  her  tongue  down  through 
them.  If  we  remove  the  anthers  and  the  pedestal,  we  shall  find  below  the 
latter,  a treasure  cave;  it  is  carpeted  with  the  softest  of  buff  velvet,  and 
while  it  does  not  reek  with  nectar,  as  does  the  cup  which  encompasses  the 
styles  of  the  pistil,  yet  it  secretes  enough  of  the  sweet  fluid  so  that  we  can 
taste  it  distinctly.  Thus,  although  the  bees  find  pollen  in  this  flower  they 
also  find  there,  nectar.  The  pumpkin  is  absolutely  dependent  upon  the 
work  of  bees  and  other  insects  for  carrying  its  pollen  from  the  blossom 
that  bears  it  to  the  one  which  needs  it,  as  this  is  the  only  way  that  the 
fruit  maybe  developed. 

And  after  the  pollen  has  been  shed  and  delivered,  the  flower  closes, 
this  time  with  an  air  of  finality.  The  fading  corolla  looks  as  if  its  lobes 
had  been  twisted  about  by  the  thumb  and  finger  to  secure  tightness ; and 
woe  betide  the  bee  caught  in  one  of  these  prisons,  unless  she  knows  how  to 
cut  through  its  walls  or  can  find  within,  sustenance  to  last  until  the 
withered  flower  falls.  The  young  pumpkin  is  at  first  held  up  by  its  stiff 
stem  but  later  rests  upon  the  ground  . 

The  ripe  pumpkin  is  not  only  a colossal  but  also  a beautiful  fruit.  The 
glossy  rind  is  brilliant  orange  and  makes  a very  efficient  protection  for  the 
treasures  within  it.  The  stem  is  strong,  five-angled  and  stubborn,  and 
will  not  let  go  its  hold  until  the  fruit  is  over-ripe.  It  t en  leaves  a star- 
shaped scar  to  match  the  one  at  the  ther  end  of  the  fruit,  where  once  the 
blossom  sat  enthroned.  The  pumpkin  in  shape  is  like  a little  world 
flattened  at  the  poles,  and  with  the  lines  of  longitude  creased  into  its 
surface.  But  the  number  of  these  longitudinal  creases  varies  with 
individual  pumpkins,  and  seems  to  have  no 
relation  to  the  angles  of  the  stem  or  the  three 
chambers  within. 

If  we  cut  a small  green  pumpkin  across,  we 
find  the  entire  inside  solid  There  are  three 
fibrous  partitions  extending  from  the  center, 
dividing  the  pulp  into  thirds;  at  its  outer  end 
each  partition  divides,  and  the  two  ends  curve 
in  opposite  directions.  Within  these  curves 
the  seeds  are  borne.  A similar  arrangement 
is  seen  in  the  sliced  cucumber.  As  the  pump- 
kin ripens,  the  partitions  surrounding  the 
seeds  become  stringy  and  very  different  from 
the  “meat”  next  to  the  rind,  which  makes  a 
thick,  solid  outer  wall  about  the  central 
chamber,  where,  within  its  “groined  arches”  are  contained  six 
rows  of  crowded  seeds,  attached  by  their  pointed  tips  and  supported 
by  a network  of  yellow,  coarse  fibers — like  babies  supported  in  hammocks. 
All  this  network,  making  a loose  and  fibrous  core,  allows  the  seeds  to  fall 
out  in  a mass  when  the  pumpkin  is  broken.  If  we  observe  where  the 
cattle  have  been  eating  pumpkins  we  find  these  masses  of  seeds  left  and 
trampled  into  the  mud,  where,  if  our  winter  climate  permitted,  they 
could  grow  into  plants  next  year.

The  pumpkin  seed  is  attached  by  its  pointed  end; 
it  is  flat,  oblong  and  has  a rounded  ridge  at  its  edge, 
within  which  is  a delicate  “beading.”  The  outside  is

seed-coats,  is  covered  with  a greenish,  membranous  coat.  The 
meat  falls  apart  lengthwise  and  flatwise,  the  two 
halves  forming  later  the  seed-leaves  and  containing 
the  food  laid  up  by  the  “pumpkin  mother”  for  the  nourishment 
of  the  young  plant.  Between  these  two  halves,  at  the  pointed 
end,  is  the  germ,  which  will  develop  into  a new  plant. 

When  sprouting,  the  root  pushes  out  through  the  pointed  end 
of  the  seed’  and  grows  downward.  The  shell  of  the  seed  is  forced 
open  by  a little  wedge-shaped  projection,  while  the 
seed-leaves  are  pulled  from  their  snug  quarters.  In 
watching  one  of  these  seeds  sprout,  it  is  difficult  not 
to  attribute  to  it  conscious  effort,  while  it  is  sturdily 
pulling  hard  to  release  its  seed-leaves.  If  it  fails  to

erence between  a jolly  grin  and  an  “awful  face.” 

LESSON  CLXXII 
The  Pumpkin 


Leading  thought — The  pumpkin  and  squash  were  cultivated  by  the 
American  Indians  in  their  cornfields  long  before  Columbus  discovered  the 
new  world.  The  flowers  of  these  plants  depend  entirely  upon  insects  for 
carrying  their  pollen,  and  are  unable  to  develop  their  fruit  without  this 
aid. 

Method — This  work  may  be  done  in  the  garden  or  field  in  September  or 
early  October;  or  a vine  bearing  both  kinds  of  flowers,  leaves  and  tendrils 
may  be  brought  to  the  schoolroom  for  observation.  The  lesson  on  the 
pumpkin  fruit  may  be  given  later.  A small  green  pumpkin  should  be 
studied  with  the  ripe  one,  and  also  with  the  blossoms,  so  as  to  show  the 
position  of  the  seeds  during  development.  This  lesson  can  be  modified 
to  fit  the  cucumber,  the  melon  and  the  squash. 


The  Pumpkin  Vine  and  Flowers 

Observations — i.  How  many  different  forms  of  flowers  do  you  find  on 
a pumpkin  vine?  What  are  the  chief  differences  in  their  shape? 

2.  Look  first  at  the  flowers  with  the  long  slender  stems : What  is  the 

shape  and  color  of  the  blossom ? How  many  lobes  has  it?  Is  each  lobe

distinctly  ribbed  or  veined?  Is  the  flower  smooth  on  the  inner  and  the 
outer  surface  ? Are  the  edges  of  the  lobes  scalloped  or  ruffled  ? 

3.  What  do  you  see  at  the  bottom  of  the  golden  vase  of  this  flower? 
This  yellow  club,  or  knob,  is  formed  by  the  joining  of  three  anthers,  one  of 
which  is  smaller  than  the  others.  Do  all  the  pumpkin  flowers  have  this 
knob  at  the  center?  Look  at  the  base  of  the  standard  which  bears  the 
anther-knob,  and  note  if  there  are  some  openings;  how  many?  Cut  off 
the  anther  pedestal,  and  describe  what  is  hidden  beneath  it.  Note  if  the 
bees  find  the  openings  to  the  nectar-well  and  probe  there  for  the  nectar. 
Do  they  become  dusted  with  pollen  while  seeking  the  nectar? 

4.  What  color  is  the  pollen  which  is  clinging  to  the  anther?  Is  it  soft 
and  light,  or  moist  and  sticky?  Do  you  think  that  the  wind  would  be 
able  to  lift  it  from  its  deep  cup  and  carry  it  to  the  cup  of  another  flower? 

5.  Describe  the  calyx  behind  this  pollen -bearing  flower.  How  many 
lobes  has  it?  Are  the  lobes  slender  and  pointed? 

6.  Find  one  of  the  flowers  which  has  below  it  a little  green  globe, 
which  will  later  develop  into  a pumpkin.  How  does  this  flower  differ 
from  the  one  that  bears  the  pollen  ? 

7.  Describe  or  sketch  the  pistil  which  is  at  the  bottom  of  this  flower 
vase.  Into  how  many  lobes  does  it  divide?  Do  these  three  stigmas  face 
outward,  or  toward  each  other?  Are  the  styles  which  uphold  the  stigmas 
short  or  long?  Describe  the  cup  in  which  they  stand.  Break  away  a bit 
of  this  little  yellow  cup  and  taste  it.  Why  do  you  think  the  pumpkin 
flowers  need  such  a large  and  well-filled  nectary?  Could  insects  get  the 
nectar  from  the  cup  without  rubbing  against  the  stigmas,  the  pollen  with

which  they  became  so  thoroughly  dusted  when  they  visited  the  staminate 
flowers? 

8.  Cut  through  the  center  of  one  of  the  small  green  pumpkins.  Can 
you  see  into  how  many  sections  it  is  divided?  Does  the  number  of  seed- 
clusters  correspond  with  the  number  of  stigmas  in  the  flower?  Make  a 
sketch  of  a cross-section,  showing  where  the  seeds  are  placed. 

9 . What  insects  do  you  find  visiting  the  pumpkin  flowers  ? 

10.  Carefully  unfold  a flower  bud  which  is  nearly  ready  to  open,  and 
note  how  it  is  folded.  Then  notice  late  in  the  afternoon  how  the  fl  wer 
closes.  What  part  is  folded  over  first ? What  next?  How  does  it  look 
when  closed? 

n.  Describe  the  stems  of  the  pumpkin  vine;  how  are  they 
strengthened  and  protected?  Sketch  or  describe  a pumpkin  leaf. 

12.  Describe  one  of  the  tendrils  of  the  pumpkin  vine.  Do  you  think 
that  these  tendrils  could  help  the  vine  in  climbing?  Have  you  ever 
found  a pumpkin  vine  climbing  up  any  object? 

The  Pumpkin  Fruit 

Observations — i.  Do  you  think  the  pumpkin  is  a beautiful  fruit? 
Why?  Describe  its  shape  and  the  way  it  is  creased.  Describe  the  rind, 
its  color  and  its  texture,  and  tell  how  it  protects  the  fruit.  Describe  the 

stem;  does  it  cling  to  the  pump- 
kin? How  many  ridges  in  the 
stem  where  it  joins  the  vine? 
How  many  where  it  joins  the 
pumpkin?  Which  part  of  the 
stem  is  larger?  Does  this  give  it 
a firmer  hold? 

2.  Cut  in  halves  crosswise  a 
small  green  pumpkin  and  a ripe 
one.  Which  is  the  most  solid? 
Can  you  see  how  the  seeds  are 
borne  in  the  green  pumpkin  ? 
How  do  they  look  in  the  ripe 
pumpkin?  What  is  next  to  the 
rmd  in  the  ripe  fruit  ? What  part 
of  the  pumpkin  do  we  use  for  pies? 

3.  Can  you  see  in  the  ripe 
pumpkin  where  the  seeds  are 
borne?  How  are  they  suspended? 
How  many  rows  of  seeds  length- 
wise of  the  pumpkin?  Of  what 
use  could  it  be  to  the  pumpkin  to 
have  the  seeds  thus  suspended 
within  it  by  these  threads  or 
fibers?  What  is  left  of  a pumpkin 
after  the  cattle  have  eaten  it? 
Might  the  seeds  thus  left  plant 
themselves? 

4.  Is  the  pumpkin  seed  at- 
tached at  the  round,  or  the  pointed,  end?  Describe  the  pumpkin  seed  its 
shape  and  its  edges?  How  does  it  feel  when  first  taken  from  the 
pumpkin?  How  many  coats  has  the  seed? 


Cultivated-Plant  Study

5.  Describe  the  meat  of  the  seed?  Does  it  divide  naturally  into  two 
parts?  Can  you  see  the  little  germ?  Have  you  ever  tried  roasting  and 
salting  pumpkin  and  squash  seeds,  to  prepare  them  for  food  as  almonds 
and  peanuts  are  prepared  ? 

6.  Plant  a pumpkin  seed  in  damp  sand  and  give  it  warmth  and  light. 
From  which  end  does  it  sprout  ? What  comes  first,  the  root  or  the  leaves  ? 
What  part  of  the  seed  forms  the  seed-leaves? 

7.  Describe  how  the  pumpkin  sprout  pries  open  the  shell  to  its  seed, 
in  order  to  get  its  seed-leaves  out.  What  happens  if  it  does  not  pull  them 
out  ? Which  part  of  the  seedling  pumpkin  appears  above  ground  first  ? 

8.  How  do  the  true  leaves  differ  in  shape  from  the  seed-leaves.  What 
is  the  use  of  the  seed-leaves  to  the  plant  ? 


Ah!  on  Thanksgiving  day , when  from  East  and  from  West, 

From  North  and  from  South  come  the  pilgrim  and  guest, 

When  the  gray-haired  New-Englander  sees  round  his  board 
The  old  broken  lines  of  affection  restored, 

When  the  care-wearied  man  seeks  his  mother  once  more, 

And  the  worn  matron  smiles  where  the  girl  smiled  before, 

What  moistens  the  lip  and  brightens  the  eye? 

What  calls  back  the  past,  like  the  rich  Pumpkin  pie? 

Oh,  fruit  loved  of  boyhood!  the  old  days  recalling, 

When  wood-grapes  were  purpling  and  brown  nuts  were  falling 
When  wild,  ugly  faces  we  carved  in  its  skin, 

Glaring  out  through  the  dark  with  a candle  within! 

When  we  laughed  round  the  corn-heap,  with  hearts  all  in  tune, 

Our  chair  a broad  pumpkin — our  lantern  the  moon, 

Telling  tales  of  the  fairy  who  travelled  like  steam, 

In  a pumpkin-shell  coach,  with  two  rats  for  her  team! 

— J.  G.  Whittier.

FERNS 

ANY  interesting  things  about  ferns  may  be 
taught  to  the  young  child,  but  the  more  care- 
ful study  of  these  plants  is  better  adapted  to 
the  pupils  in  the  higher  grades,  and  is  one  ot 
the  wide-open  doors  that  leads  directly  from 
nature-study  to  systematic  science.  While 
the  pupils  are  studying  the  different  forms  in 
which  ferns  bear  their  fruit,  they  can  make 
collections  of  all  the  ferns  of  the  locality. 
Since  ferns  are  easily  pressed  and  are  beauti- 
ful objects  when  mounted  on  white  paper,  the 
making  of  a fern  herbarium  is  a delightful  pastime ; or  leaf-prints  may  be 
made  which  give  beautiful  results  (see  page  734)  ;but,  better  perhaps,  than 
either  collections  or  prints,  are  pencil  or  water-color  drawings  with  details 
of  the  fruiting  organs  enlarged.  Such  a portfolio  is  not  only  a thing  of 
beauty  but  the  close  observation  needed  for  drawing  brings  much 
knowledge  to  the  artist.

THE  CHRISTMAS  FERN 
Teacher's  Story 

“No  shivering  frond  that  shuns  the  blast  sways  on  its  slender  chaffy  stem ; 

Full  veined  and  lusty  green  it  stands,  of  all  the  wintry  woods  the  gem.  ” 

— W.  N.  Clute. 

The  rootstock  of  the  fern  is  an  humble  example  of  “rising  on  stepping 
stones  of  our  dead  selves,”  this  being  almost  literally  true  of  the  tree-ferns. 
The  rootstock  which  is  a stem  and  not  a root — has,  like  other  stems,  a 
growing  tip  from  which,  each  year,  it  sends  up  into  the  world  several 
beautiful  green  fronds,  and  numerous  rootlets  down  into  the  earth. 
These  graceful  fronds  rejoice  the  world  and  our  eyes  for  the  summer,  and 
make  glad  the  one  who,  in  winter,  loves  to  wander  often  in  the  woods  to 
inquire  after  the  welfare  of  his  many  friends  during  their  period  of  sleeping 
and  waking.  These  fronds,  after  giving  their  message  of  winter  cheer, 
and  after  the  following  summer  has  made  the  whole  woodland  green  and 
the  young  fronds  are  growing  thriftily  from  the  tip  of  the  rootstock,  die 
down,  and  in  midsummer  we  can  find  the  old  fronds  lying  sere  and  brown, 
with  broken  stipes,  just  back  of  the  new  fern  clump;  if  we  examine  the 
rootstock  we  can  detect  behind  them,  remains  of  the  stems  of  the  fronds  of 
year  before  last ; and  still  farther  behind  we  may  trace  all  the  stems  of 
fronds  which  gladdened  the  world  three  years  ago.  Thus  we  learn  that

fruiting  pinna.

this  rootstock  may  have  been  creeping  on  an  inch  or  so  each  season  for 
many  years,  always  busy  with  the  present  and  giving  no  heed  to  its  dead 
past.  One  of  the  chief  differences  between  our  ferns  and  the  tree-ferns  of 
the  tropics,  which  we  often  see  in  greenhouses,  is  that  in  the  tree-fern  the 
rootstock  rises  in  the  air  instead  of  creeping  on,  or  below,  the  surface  of  the 
ground.  This  upright  rootstock  of  the  tree-fern  also  bears  fronds  at  its 
tip,  and  its  old  fronds  gradually  die  down,  leaving  it  rough  below  its  crown 
of  green  plumes. 

The  Christmas  fern  has  its  green  stipe,  or  petiole,  and  its  rachis,  or  mid- 
rib, more  or  less  covered  with  ragged,  brownish  scales,  which  give  it  an 
unkempt  appearance.  Its  pinnae,  or  leaflets,  are  individually  very 
pretty;  in  color  they  are  dark,  shining  green,  lance-shaped,  with  a pointed 
lobe  or  ear  at  the  base  projecting  upward.  The  edges  of  the  pinnae  are 
delicately  toothed,  each  point  armed  with  a little  spine,  and  the  veins  are 
fine,  straight  and  free  to  the  margin;  the  lower  pinnae  often  have  the 
earlike  lobe  completely  severed. 

; In  studying  a fertile  fern  from  above,  we  notice  that  about  a dozen 
pairs  of  the  pinnae  near  the  tip  are  narrowed  and  roughened  and  are 
more  distinctly  toothed  on  the  margins.  Examining  them  underneath, 
we  find,  on  each  a double  row  of  circular  raised  dots  which  are  the  fruit- 
dots,  or  sori;  there  is  a row  between  the  midrib  and  margin  on  each  side, 
and  also  a double  row  extending  up  into  the  point  at  the  base.  Early  in 
the  season  these  spots  look  like  pale  blisters,  later  they  turn  pale  brown, 
each  blister  having  a depression  at  its  center;  by  the  middle  of  June, 


686 


Handbook  of  Nature-Study 


masses  of  tiny  globules,  not  larger  than  pin  points,  push  out  from  beneath 
the  margin  of  these  dots.  The  blisterlike  membrane  is  simply  a cover  for 
the  growing  spores,  and  is  called  the  indusium;  by  July  it  shrivels  into  an 
irregular  scroll,  still  clinging  to  the  pinnule  by  its  depressed  center;  and 

by  this  time  the  profu- 
sion of  tiny  globules 
covers  the  entire  under 
side  of  the  pinna  like 
a brown  fuzz.  If  we 
scrape  off  some  of  this 
fuzz  and  examine  it  with 
a lens,  we  can  see  that  it 
consists  of  numberless 
little  globules,  each  with 
a stem  to  attach  it  to  the 
leaf ; these  are  the  spore- 
cases,  or  sporangia,  each 
globule  being  packed  full 
of  spores  which,  even 
through  the  lens,  look 
like  yellowish  powder. 
But  each  particle  of  this 
dust  has  its  own  structure  and  contains  in  its  heart  the  living  fern-sub- 
stance. 

Not  all  the  fronds  of  the  fern  clump  bear  these  fruit-dots.  The  ones 
we  select  for  decoration  are  usually  the  sterile  fronds,  for  the  fertile  ones 
are  not  so  graceful,  and  many  ignorant  people  think  the  brown  spore-cases 
are  a fungus.  The  Christmas  fern  being  evergreen  and  very  firm  in  tex-

cure,  is  much  used  in  holiday  decoration,  hence  its  common  name,  which 
is  more  easily  remembered  than  Polystichum  acrostichoides , which  is  its 
real  name.  It  loves  to  grow  in  well-shaded  woodlands,  liking  better  the 
trees  which  shed  their  leaves  than  the  evergreens;  it  is  indeed  well- 
adapted  to  thrive  in  damp,  cold  shade;  it  is  rarely  found  on  slopes  which 
face  the  south,  and  sunshine  kills  it. 


LESSON  CLXXIII 
The  Christmas  Fern 

Leading  thought — The  fern  has  a creeping  underground  stem  called  the 
rootstock,  which  pushes  forward  and  sends  up  fresh  fronds  each  year, 
Some  of  the  fronds  of  the  Christmas  fern  bear  spores  on  the  lower  surface 
of  the  terminal  pinnae. 

Method — This  lesson  should  be  given  during  the  latter  part  of  May, 
when  the  fruit-dots  are  still  green.  Take  up  a fern  and  transplant  it,  in  a 
dish  of  moss,  in  the  schoolroom,  and  later  plant  it  in  some  convenient 
shady  place.  The  pupils  should  sketch  the  fertile  frond  from  the  upper 
side  so  as  to  fix  in  their  minds  the  contracted  pinnae  of  the  tip;  one  of 
the  lower  pinnae  should  be  drawn  in  detail,  showing  the  serrate  edge, 
the  ear  and  the  venation.  The  teacher  should  use  the  following  terms 
constantly  and  insis- 
tently, so  as  to  make 
the  fern  nomencla- 
ture a part  of  the 
school  vocabulary, 
and  thus  fit  the 
pupils  for  using  fern 
manuals. 

A frond  is  all  of 
the  fern  which  grows 
on  one  stem  from  the 
rootstock;  the  blade 
is  that  portion  which 
bears  leaflets;  the 
stipe  is  the  stem  or 
petiole;  the rachis is 
the  midrib  and  is  a 
continuation  of  the 
stipe ; the  pinnule 
is  a leaflet  of  the  last 
division;  the  pinna 
is  a chief  division  of 
the  midrib  or  rachis, 
when  the  fern  is  com- 
pound; the  sori  are 
the  fruit  dots;  the 
mdusium  isthe  mem- 
brane covering  the 
fruiting  organs;  the 
sporcngia  are  the 

tiny  brown  globules.  Leaf-print  of  a fern  with  the  parts  named .

cases;  the  spores  make  up  the  fine  dust  which  comes  from  the  spore-cases. 
It  would  be  well  to  make  a diagram  on  the  blackboard  of  the  fern  with  its 
parts  named,  so  that  the  pupils  may  consult  it  while  studying  ferns. 

Observations  — i.  Study  a stump  of  the  Christmas  ferns.  Are  there  any 
withered  fronds  ? Where  do  they  join  the  rootstock?  Do  the  green  fronds 
come  from  the  same  place  on  the  rootstock  as  the  withered  ones  ? Do  the 
green  ferns  come  from  near  the  tip  of  the  rootstock?  Can  you  find  the 
growing  tip  of  the  rootstock?  Can  you  trace  back  and  find  where  the 
fronds  of  last  year  and  year  before  last  grew?  Does  that  part  of  the  root- 
stock  seem  alive  now?  Can  you  find  the  true  root  of  the  fern? 

2.  Take  a frond  of  the  Christmas  fern.  Is  the  stem,  or  stipe,  and  the 
midrib,  or  rachis,  smooth  or  rough  ? What  color  are  the  scales  of  the 
stalk?  Do  you  think  that  these  scales  once  wrapped  the  fern  bud? 

3.  Does  each  frond  of  a clump  have  the  same  number  of  pinnae  on 
each  side?  Can  you  find  fronds  where  the  pinnae  near  the  tip  are  nar- 
rower than  those  below?  Take  a lower  pinna  and  draw  it  carefully, 
showing  its  shape,  its  edges  and  its  veins.  Is  there  a point,  or  ear,  at 
the  base  of  every  pinna?  Is  it  a separate  lobe  or  a mere  point  of  the 
pinna  ? 

4.  Take  one  of  the  narrow  pinnae  near  the  tip  of  the  frond,  and 
examine  it  beneath.  Can  you  see  some  circular,  roundish  blisterlike 
dots?  Are  they  dented  at  the  center?  How  many  of  these  dots  on  a 
pinna?  Make  a little  sketch  showing  how  they  are  arranged  on  the 
pinna  and  on  the  little  earlike  point.  Look  at  the  fruiting  pinnae  of 
a fern  during  July,  and  describe  how  they  look  then. 

5.  Do  all  the  fronds  of  a fern  clump  have  these  narrowed  spore- 
bearing pinnae?  Do  you  know  what  those  fronds  are  called  that  beai 
the  fruit-dots? 

6.  Where  do  you  find  the  Christmas  fern  growing?  Do  you  ever  find 
it  in  a sunny  place?  Why  is  it  called  the  Christmas  fern? 


FERN  SONG 

Dance  to  the  heat  of  the  rain,  little  Fern 
And  spread  out  your  palms  again, 

And  say,  “ Tho ’ the  sun 
Hath  my  vesture  spun, 

He  had  labored,  alas,  in  vain, 

But  for  the  shade 

That  the  Cloud  hath  made, 

And  the  gift  of  the  Dew  and  the  Rain.” 

Then  laugh  and  upturn 
All  your  fronds,  little  Fern, 

And  rejoice  in  the  beat  of  the  rain!

THE  BRACKEN 


689 


Teacher's  Story 

It  is  well  for  the 
children  to  study  the 
animals  and  plants 
which  have  a world- 
w i d e distribution. 
There  is  something 
comforting  in  finding 
a familiar  plant  in 
strange  countries ; and 
when  I have  found 
the  bracken  on  the 
coast  ranges  of  Cali- 
fornia, on  the  rugged 
sides  of  the  Alps,  and 
in  many  other  far 
places,  I have  always 
experienced  a thrill  of 
delightful  memories  of 
the  fence  corners  of 
the  homestead  farm. 
Since  the  bracken  is 
so  widespread,  it  is 
natural  that  it  should 
find  a place  in  litera- 
ture and  popular 
legend.  As  it  clothes 
the  mountains  of  Scot- 
land, it  is  much  sung 
of  in  Scottish  poetry. 
Many  superstitions 
cluster  around  it — its 
seed,  if  caught  at 
midnight  on  a white 
napkin,  is  supposed  to 
render  the  possessor 
invisible.  Professor 
Clute,  in  Our  Ferns  in 
Their  Haunts,  gives  a 
delightful  chapter 
about  the  relation  of 
the  bracken  to  people. 

For  nature-study 
purposes,  the  bracken 
is  valuable  as  a lesson 
on  the  intricate  pat- 
terns of  the  fern  leaf; 
it  is  in  fact  a lesson  in 
pinnateness.  The  two 
lower  branches  are 
large  and  spreading'

Handbook  of  Nature-Study 


and  are  in  themselves  often  three  times  pinnate ; the  branches  higher  up 
are  twice  pinnate ; while  the  main  branch  near  the  tip  is  once  pinnate,  and 
at  the  tip  is  merely  lobed.  The  lesson,  as  illustrated  in  the  diagram  of  the 
fern,  should  be  well  learned  for  future  study,  because  this  nomenclature  is 
used  in  all  the  fern  manuals.  The  fact  that  a pinnule  is  merely  the  last 
division  of  a frond,  whether  it  be  twice  or  thrice  pinnate,  should 
also  be  understood. 

The  bracken  does  not  love  complete  shade  and  establishes  itself  in 
waste  places,  living  contentedly  in  not  too  shaded  locations ; it  is  especially 
fond  of  woodsides,  and  fence  corners  on  high  and  cold  land.  As  Professor 
Clute  says,  “It  is  found  both  in  woodland  and  in  the  open  field;  its  favor- 
ite haunt  is  neither,  but  is  that  half-way  ground  where  man  leaves  off  and 
nature  begins,  the  copse  or  the  thicket.”  With  us  it  usually  grows  c^bout 
three  feet  high,  but  varies  much  in  this  respect.  The  great  triangular 
fronds  often  measure  two  or  three  feet  across,  and  are  supposed  to  bear  a 
likeness  to  an  eagle  with  spread  wings.  Its  rootstock  is  usually  too 
deeply  embedded  in  earth  for  the  study  of  any  except  the  most  energetic; 
it  is  about  the  size  of  a lead  pencil  and  is  black  and  smooth ; in  its  way  it 
is  a great  traveler,  sending  up  fronds  fifteen  or  twenty  feet  from  its  start- 
ing place.  It  also  sends  off  branching  rootstocks. 

The  fruiting  pinnules 
look  as  if  they  were  hemmed 
and  the  edges  of  the  hems 
embroidered  with  brown 
wool;  but  the  embroidery 
is  simply  the  spore-cases 
pushing  out  from  under 
the  folded  margin  which 
protected  them  while  de- 
veloping. 

Much  on  which  to  base 
necromancy  has  been  found 
in  the  figure  shown  in  the 
cross-section  of  the  Stem  or  7 J-  fruiting  pinnules  of  the  maiden-hair  fern,  en-

tection from  witches.  But  this  figure  has  also  been  compared  to  the 
devil’s  hoof,  an  oak  tree,  or  the  initial  of  one’s  sweetheart,  and  all  these 
imaginings  have  played  their  part  in  the  lives  of  the  people  of  past  ages. 
It  was  believed  in  England  that  burning  the  bracken  from  the  fields 
brought  rain ; the  roots  in  time  of  scarcity  have  been  ground  and  mixed 
with  flour  to  make  bread.  The  young  ferns,  or  croziers,  are  sometimes 
cooked  and  eaten  like  asparagus.  The  fronds  have  been  used  extensively 
for  tanning  leather  and  for  packing  fish  and  fruit,  and  when  burned  theii 
ashes  are  used  instead  of  soap. 

In  Europe,  bracken  grows  so  rankly  that  it  is  used  for  roof-thatching 
and  for  the  bedding  of  cattle.  The  name  “brake,”  which  is  loosely  used 
for  all  ferns,  comes  from  the  word  “bracken;”  some  people  think  that 
brakes  are  different  from  ferns,  whereas  this  is  simply  a name  which  has 
strayed  from  the  bracken  to  other  species.  Its  scientific  name,  Pteris 
aquilina,  signifies  eagle’s  wing.

LESSON  CLXXIV 
The  Bracken 

Leading  thought — The  bracken  is  a fern  which  has  taken  possession  of 
the  world.  It  is  much  branched  and  divided,  and  it  covers  the  ground  in 
masses  where  it  grows.  The  edges  of  its  pinnules  are  folded  under  to  pro- 
tect the  spores. 

Method — Bring  to  the  schoolroom  large  and  small  specimens  of  the 
bracken,  and  after  a study  is  made  tell  about  the  superstitions  connected 
with  this  fern  and  as  far  as  possible  interest  the  pupils  in  its  literature. 

Observations — 1.  Do  you  find  the  bracken  growing  in  the  woods  or 
open  places?  Do  you  find  it  in  the  cultivated  fields?  How  high  does  it 
stand?  Could  you  find  the  rootstock? 

2.  Take  a bracken  frond.  What  is  its  general  shape?  Does  it 
remind  you  of  an  eagle  with  spread  wings?  Look  at  its  very  tip.  Is  it 
pinnate  or  merely  lobed?  Can  you  find  a place  farther  down  where  the 
leaflets,  or  pinnules,  are  not  joined  at  their  bases?  This  is  once  pinnate. 
Look  farther  down  and  find  a pinna  that  is  lobed  at  the  tip ; at  the  base 
it  has  distinct  pinnules.  This  is  twice  pinnate.  Look  at  the  lowest 
divisions  of  all.  Can  you  find  any  part  of  this  which  is  three  times  pin- 
nate? Four  times  pinnate?  Pinna  means  feather,  pinnate  therefore 
means  feathered.  If  a thing  is  once  pinnate,  it  means  that  it  has  divisions 
along  each  side  similar  to  q feather;  twice  pinnate  means  that  each 
feather  has  little  feathers  along  each  side ; thrice  pinnate  means  that  the 
little  feathers  have  similar  feathers  along  each  side,  and  so  on. 

3.  Can  you  see  if  the  edges  of  the  pinnules  are  folded  under?  Lift  up 
one  of  these  edges  and  see  if  you  can  find  what  is  growing  beneath  it. 
How  do  these  folded  margins  look  during  August  and  September? 

4.  Cut  the  stem,  or  stipe,  of  a bracken  across  and  see  the  figure  in  it. 
Does  it  look  like  the  initial  C?  Or  a hoof,  or  an  oak  tree,  or  another 
initial? 

5.  Discover,  if  you  can,  the  different  uses  which  people  of  other 
countries  find  for  this  fern. 


HOW  A FERN  BUD  UNFOLDS 

Teacher's  Story 

Of  all  "plant  babies,”  that  of  the  fern  is  most  cozily  cuddled;  one  feels 
when  looking  at  it,  that  not  only  are  its  eyes  shut  but  its  fists  are 
tightly  closed.  But  the  first  glance  at  one  of  these  little  woolly  spirals 
gives  us  but  small  conception  of  its  marvelous  enfolding,  all  so  systematic 
and  perfect  that  it  seems  another  evidence  of  the  divine  origin  of  mathe- 
matics. Every  part  of  the  frond  is  present  in  that  bud,  even  to  the 
fruiting  organs;  all  the  pinnae  and  the  pinnules  are  packed  in  the 
smallest  compass — each  division,  even  to  the  smallest  pinnule,  coiled  in 
a spiral  towards  its  base.  These  coiled  fern  buds  are  called  crosiers ; 
they  are  woolly,  with  scales  instead  of  hairs,  and  are  thus  well  blanketed. 
Some  botanists  object  to  the  comparison  of  the  woolly  or  fuzzy  clothing  of 
young  plants  with  the  blankets  of  human  infants.  It  is  true  that  the  young 
plant  is  not  kept  at  a higher  temperature  by  this  covering;  but  because 
of  it,  transpiration  which  is  a cooling  process  is  prevented,  and  thus  the

plant  is  kept  warmer.  When  the  fern  commences  to  grow,  it  stretches  up 
and  seems  to  lean  over  backward  in  its  effort  to  be  bigger.  First  the  main 

stem,  or  rachis,  loosens  its 
coil;  but  before  this  is  com- 
pleted, the  pinnas,  which 
are  coiled  at  right  angles  to 
the  main  stem,  begin  to  un- 
fold; a little  later  the  pin- 
nules, which  are  folded  at 
right  angles  to  the  pinnae, 
loosen  and  seem  to  stretch 
and  yawn  before  taking  a 
look  at  the  world  which 
they  have  just  entered;  it 
may  be  several  days  before 
all  signs  of  the  complex  coil- 
ing disappear.  The  crosiers 
of  the  bracken  are  queer  look- 
ing creatures,  soon  develop- 
ing three  claws  which  some 
people  say  look  like  the 
talons  of  an  eagle;  and  so 
intricate  is  the  action  of  their 
multitudinous  spirals,  that 
to  watch  them  unfolding  im- 
presses one  as  in  the  presence 
of  a miracle.

ally within  the  bud,  and 
every  lobe  of  every  leaflet  is  also  folded  in  a spiral. 

Method — The  bracken  crosier  is  a most  illuminating  object  for  this 
lesson,  because  it  has  so  many  divisions  and  is  so  large;  it  is  also  con- 
venient, because  it  may  be  found  in  September.  However,  any  fern  bud 
will  do.  The  lesson  may  be  best  given  in  May  when  the  woodland  ferns 
are  starting.  A fern  root  with  its  buds  should  be  brought  to  the  school- 
room, where  the  process  of  unfolding  may  be  watched  at  leisure. 

Observations — 1.  Take  a very  young  bud.  How  does  it  look?  Do 
you  see  any  reason  why  ignorant  people  call  these  buds  caterpillars  ? Can 
you  see  why  they  are  popiilarly  called  “fiddle  heads?”  What  is  their  true 
name?  How  many  turns  of  the  coil  can  you  count.?  Whar  ■>  j the  cover- 
ing of  the  crosier?  Do  you  think  this  cover  is  a protection?  How  is  the 
stem  grooved  to  make  the  spiral  compact  ? 

2.  Take  a crosier  a little  further  advanced.  How  are  its  pinnae  folded? 
How  is  each  pinnule  of  each  pinna  folded  ? How  is  each  lobe  of  a pinnule 
folded?  Is  each  smaller  part  coiled  toward  each  larger  part?

THE  FRUITING  OF  THE  FERN 

Teacher's  Story 

“If  we  were  required  to  know  the  position  of  the  fruit-dots  or  the  character  of  the 
indusium,  nothing  could  he  easier  than  to  ascertain  it;  hut  if  it  is  required  that  you  he 
affected  by  ferns,  that  they  amount  to  anything,  signify  anything  to  you,  that  they  he 
another  sacred  scripture  and  revelation  to  you,  help  to  redeem  your  life,  this  end  is  not  so 
easily  accomplished .” — Thoreau. 

HE  fern,  like  the  butterfly,  seems  to  have  sev- 
eral this-world  incarnations;  and  perhaps 
the  most  wonderful  of  these  is  the  spore. 
Shake  the  dust  out  of  the  ripened  fern  and 
each  particle,  although  too  small  for  the 
naked  eye  to  see,  has  within  it  the  possibili- 
ties of  developing  a mass  of  graceful  ferns. 
Each  spore  has  an  outside  hard  layer,  and 
within  this  an  atom  of  fern-substance ; but 
it  cannot  be  developed  unless  it  falls  into 
some  warm,  damp  place  favorable  for  its 
growth ; it  may  have  to  wait  many  years 
before  chance  gives  it  this  favorable  con- 
dition, but  it  is  strong  and  patient  and 
retains  its  vital  power  for  years.  There 
are  cases  known  where  spores  grew  after  twenty  years  of  waiting. 
But  what  does  this  microscopic  atom  grow  into?  It  develops  into  a 
tiny  heart-shaped,  leaflike  structure  which  botanists  call  the 
prothallium;  this  has  on  its  lower  side  little  roots  which  reach  down 
into  the  soil  for  nourishment;  and  on  its  upper  surface  are  two 
kinds  of  pockets,  one  round  and  the  other  long.  In  the  round 
pockets  are  developed  bodies  which  may  be  compared  to  the  pollen; 
and  in  the  long  pockets,  bodies  which  may  be  compared  to  the  ovules 
of  flowering  plants.  In  the  case  of  ferns,  water  is  necessary  to  float  the 
pollen  from  the  round  pockets  to  the  ovules  in 
the  long  pockets.  From  a germ  thus  fertilized 
in  one  of  the  long  pockets,  a little  green  fern 
starts  to  grow,  although  it  may  be  several  years 
before  it  becomes  a plant  strong  enough  to  send 
up  fronds  with  spore-dots  on  them.  To  study 
the  structure  of  the  spore  requires  the  highest 
powers  of  the  microscope ; and  even  the  prothal- 
lium in  most  species  is  very  small,  varying  from 
the  size  of  a pin-head  to  that  of  a small  pea,  and  it 
is  therefore  quite  difficult  to  find.  I found  some 
once  on  a mossy  log  that  bridged  a stream,  and  I 
was  never  so  triumphant  over  any  other  outdoor 
achievement.  They  may  be  found  in  damp

larged, showing  the  two

the  fern  to  be  compared  to  the  flower  and  seed  combined  in  the  highei 
plants ; but  this  is  difficult  for  young  minds  to  comprehend.  I like  to  tell 
the  children  that  the  fern,  like  a butterfly,  has  several  stages : Beginning 

with  the  spore-bearing 
fern,  we  next  have  the 
^ spores,  next  the  prothal- 
lium stage,  and  then  the 
young  fern.  While  in 
the  other  case  we  have 
first  the  egg,  then  the 
caterpillar,  then  the 
chrysalis,  and  then  the

the  ripe  fruit-dots  on  the 
lower  side  of  the  fern 
leaf,  we  can  easily  see 
with  a lens  a mass  of  tiny  globules;  each  one  of  these  is  a spore-case,  or 
sporangium,  (plural  sporangia),  and  is  fastened  to  the  leaf  by  a stalk 
and  has,  almost  encircling  it,  a jointed  ring.  (See  figure  on  page  686). 

When  the  spores  are  ripe,  this  ring  straightens  out  and  ruptures  the 
globule,  and  out  fly  the  spores.  By  scraping  a little  of  the  brown  fuzz 
from  a fruiting  pinna  of  the  Christmas  fern  upon  a glass  slide  and  placing  a 
cover  glass  upon  it,  we  find  it  very  easy  to  examine  through  the  micro* 
scope,  and  we  are  able  thus  to  find  the  spore-cases  in  all  stages,  and  to  see

the  spores  distinctly.  The  spore-cases  may  also  be  seen  with  a hand  lens, 
the  spores  seeming  then  to  be  mere  dust. 

The  different  ways  the  ferns  blanket 
their  spore-cases  is  a delightful  study,  and 
one  which  the  pupils  enjoy  very  much.  All 
of  our  common  ferns  except  the  careless 
little  polypody  thus  protect  their  spores. 

Whether  this  blanket  be  circular,  or  horse- 
shoe-shaped, or  oblong,  or  in  the  form  of 
pocket  or  cup,  depends  upon  the  genus  to 
which  the  fern  belongs.  The  little  protect- 
ing blanket-membrane  is  called  the  indu- 
sium,  and  while  its  shape  distinguishes  the 
genus,  the  position  in  which  it  grows 
determines  the  species.  I shall  never 
forget  my  surprise  and  delight  when,  as  a 
young  girl,  I visited  the  Philadelphia  Cen- 
tennial Expositon,  and  there  in  the  great 
conservatories  saw  for  the  first  time  the 
tree-ferns  of  the  tropics.  One  of  these  was 
labelled  Dicksonia,  and  mystified,  I asked  the  privilege  of  examining 
the  fronds  for  fruiting  organs.  When  lo!  the  indusium  proved  to  be  a 
little  cup,  borne  at  the  base  of  the  tooth  of  the  pinnule, 
exactly  like  that  of  our  boulder  fern,  which  is  also  a 
Dicksonia.  I had  a sudden  feeling  that  I must  have  fern 
friends  all  over  the  world. 

The  children  are  always  interested  in  the  way  the 
maidenhair  folds  over  the  tips  of  her  scallops  to  protect 
her  spore  nursery;  and  while  many  of  our  ferns  have 
their  fertile  fronds  very  similar  in  form  to  the  sterile  ones, 
yet  there  are  many  common  ferns  with  fertile  fronds  that 
look  so  different  from  the  others,  that  one  would  not 
think  they  were  originally  of  the  same  pattern;  but 
although  their  pinnules  are  changed  into  cups, 
or  spore-pockets,  of  various  shapes,  if  they  be 
examined  carefully  they  will  be  seen  to  have 
the  same  general  structure  and  the  same 
divisions  however  much  contracted,  as  have 
the  large  sterile  fronds.  The  Osmundas, 
which  include  the  interrupted,  the  cinnamon 
and  the  flowering  ferns,  are  especially  good  for 
this  part  of  the  lesson.  The  sensitive  fern,  so 
common  in  damp  places  in  open  fields,  is  also 
an  excellent  illustration  of  this  method  of 
fruiting.  While  studying  the  ferns,  the  teacher  should  lay  stress  upon 
the  fact  that  they  represent  the  earliest  and  simplest  forms  of  plants, 
that  they  reached  the  zenith  of  their  growth  in  the  Carboniferous  age,  and 
that,  to  a large  extent,  our  coal  is  composed  of  them.  It  is  interesting 
to  think  that  the  exquisite  and  intricate  leaf  patterns  of  the  ferns  should 
belong  to  a primitive  type.  Often  when  I have  watched  the  forming 
by  the  frost,  of  the  exquisite  fernlike  pictures  on  the  window-pane,  I 
have  wondered  if,  after  all,  the  first  expression  of  the  Creator  did  not

find  form  in  the  most  exquisite  grace  and  beauty;  and  if  perchance  the 
first  fishes,  so  fierce  and  terrible,  did  not  mark  the  introduction  of  Satan. 


LESSON  CLXXVI 
The  Fruiting  of  the  Fern 

Leading  thought — Ferns  do  not  have  flowers,  but  they  produce  spores. 
Spores  are  not  seeds ; but  they  grow  into  something  which  may  be  com- 
pared to  a true  seed,  and  this  in  turn  develops  into  young  ferns.  Each 
genus  of  ferns  has  its  own  peculiar  way  of  protecting  its  spores ; and  if  we 
learn  these  different  ways,  we  can  recognize  ferns  without  effort. 

Method — July  is  the  best  time  for  this  lesson,  which  is  well  adapted  for 
summer  schools  or  camping  trips.  However,  if  it  is  desired  to  use  it  as  a 
school  lesson,  it  should  be  begun  in  June,  when  the  fruiting  organs  are 
green,  and  it  may  be  finished  in  September  after  the  spores  are  discharged. 
Begin  with  the  Christmas  fern,  which  ripens  in  June,  and  make  the  fruit- 
ing of  this  species  a basis  for  comparison.  Follow  this  with  other  wood 
ferns  which  bear  fruit-dots  on  the  back  of  the  fronds.  Then  study  the 
ferns  which  live  in  more  open  places,  and  which  have  fronds  changed  in 
*orm  to  bear  the  spores — like  the  sensitive,  the  ostrich,  the  royal  and  the 
flowering  ferns.  A study  of  the  interrupted  fern  is  a desirable  preparation 
for  the  further  study  of  those  which  have  special  fruiting  fronds  • the

interrupted  fern  has,  at  about  the  middle  of  its  frond,  three  pinnae  on  each 
side,  fitted  for  spore-bearing,  the  pinnules  being  changed  into  globular 
cups  filled  with  spore-cases. 

While  not  absolutely  necessary,  it  is  highly  de- 
sirable that  each  member  of  the  class  should  look 
at  a fruit-dot  of  some  fern  through  a three- 
quarters  objective  of  a compound  microscope, 
and  then  examine  the  spore-cases  and  the  spores 
through  a one-sixth  objective.  It  must  be 
remembered  that  this  lesson  is  for  advanced 
grades,  and  is  a preparation  for  systematic 
scientific  work.  If  a microscope  is  not  available, 
the  work  may  be  done  with  a hand  lens  aided  by 
pictures. 

Observations — 1 . Take  a fern  that  is  in  fruit ; 
lay  it  on  a sheet  of  white  paper  and  leave  it  thus 
for  a day  or  two,  where  it  will  not  be  disturbed 
and  where  there  is  no  draught ; then  take  it  up 
carefully ; the  form  of  the  fern  will  be  outlined  in 
dust.  What  is  this  dust  ? 

2 . What  conditions  must  the  spores  have  in 
ordertogrbw?  What  do  they  grow  into?  (See 
First  Studies  of  Plant  Life  by  Atkinson,  p.  207). 

3 . Look  at  a ripe  fruit-dot  on  the  back  of  a 

fern  leaf  and  see  where  the  spores  come  from.  Can 
you  see  with  a lens  many  little,,  brown  globules?  C 

Can  you  see  that  some  of  them  are  torn  open  ? These  are  the  spore-cases, 
called  sporangia,  each  globule  being  packed  with  spores.  Can  you  see 
how  the  sporangia  are  fastened  to  the  leaf  by  little  stems? 

4.  Almost  all  our  common  wood  ferns  have  the  spore-cases  protected 
by  a thin  membrane,  the  spore-blanket,  when  very,  young ; this  little 
membrane  is  called  the  indusium,  and  it  is  of  different  sn^pe  in  those  ferns 
which  do  not  have  the  same  sirname,  or  generic  name.  Study  as  many 
kinds  of  wood  ferns  as  you  can  find.  If  the  blanket,  or  indusium,  is 
circular  with  a dent  at  the  center  where  it  is  fastened  to  the  leaf,  and  the 
spore-cases  push  out  around  the  margin,  it  is  a Christmas  fern;  if  horseshoe- 
shaped, it  is  one  of  the  wood  ferns;  if  oblong,  in  rows  on  each  side  of  the 
midrib,  it  is  a chain  fern;  but  if  oblong  and  at  an  angle  to  the  midrib,  it  is  a 
spleenwort;  if  it  is  ocket-shaped  and  opening  at  one  side,  it  is  a 
bladder  fern;  if  it  is  cup-shaped,  it  is  a boulder  fern;  if  it  breaks  open  and 
lays  back  in  star  shape,  it  is  a woodsia;  if  the  edge  of  the  fern  leaf  is  folded 
over  all  along  its  margin  to  protect  the  spore-cases,  it  is  a bracken;  if  the 
tips  of  the  scallops  of  the  leaf  be  delicately  folded  over  to  make  a spore 
blanket,  it  is  the  maidenhair. 

5 . If  you  know  of  swampy  land  where  there  are  many  tall  brakes,  look 
for  a kind  that  has  some  of  its  pinnae  withered  and  brown.  Examine 
these  withered  pinnae,  and  you  will  see  that  they  are  not  withered  at  all 
but  are  changed  into  little  cups  to  hold  spore-cases.  This  is  the  inter- 
rupted fern.  The  flowering  fern  has  the  pinnae  at  its  tip  changed  into  cups 
for  spore-cases.  The  cinnamon  fern,  which  grows  in  swampy  places,  has 
whole  fronds  which  are  cinnamon-colored  and  look  withered,  but  which 
bear  the  spores.  The  ostrich  fern,  which  has  fronds  which  look  like  mag- 


698 


Handbook  of  Nature-Study 


nificent  ostrich  feathers,  has  stiff,  little  stalks  of  fruiting  fronds  very 
unlike  the  magnificent  sterile  fronds.  The  sensitive  fern,  which  grows  in 
damp  meadows  and  along  roadsides,  also  has  contracted  fruiting  fronds. 
If  you  find  any  of  these,  compare  carefully  the  fruiting  with  the  sterile 
fronds,  and  note  in  each  case  the  resemblance  in  branching  and  in  pinnules 
and  also  the  shape  of  the  openings  through  which  the  spores  are  sifted  out. 

6.  Gather  and  press  specimens  of  as  many  ferns  in  the  fruiting  stage 
as  you  can  find,  taking  both  sterile  and  fruiting  fronds  in  those  species 
which  have  this  specialization. 

7.  Read  in  the  geologies  about  the  ferns  which  helped  to  make  our 
coal  beds.

THE  FIELD  HORSETAIL 
Teacher's  Story 

These  queer,  pale  plants  grow  in 
sandy  or  gravelly  soil,  and  since  they 
appear  so  early  in  the  spring  they  are 
objects  of  curiosity  to  children.  The 
stalk  is  pale  and  uncanny  looking; 
the  pinkish  stem,  all  the  same  size 
from  bottom  to  top,  is  ornamented  at 
intervals  with  upward-pointing, 
slender,  black,  sharp-pointed  scales, 
which  unite  at  the  bottom  and  en- 
circle the  stalk  in  a slightly  bulging 
ring,  a ring  which  shows  a ridge  for 
every  scale,  extending  down  the  stem. 

These  black  scales  are  really  leaves 
springing  from  a joint  in  the  stem,  but 
they  forgot  long  ago  how  to  do  a 
leaf’s  work  of  getting  food  from  the 
air.  The  “blossom”  which  is  not  a 
real  blossom  in  the  eye  of  the  botanist, 
is  made  up  of  rows  of  tiny  discs  which 
are  set  like  miniature  toadstools 
around  the  central  stalk.  Before  it  is 
ripe,  there  extends  back  from  the  edge 
of  each  disc  a row  of  little  sacs  stuffed 
so  full  of  green  spores  that  they  look 
united  like  a row  of  tiny  green  ridges. 

The  discs  at  the  top  of  the  fertile  spike 
discharge  their  spores  first,  as  can  be 
seen  by  shaking  the  plant  over  white 
paper,  the  falling  spores  looking  1,  Fertile  plant  of  the  field  horsetail;  2,  spore, 
like  pale  green  powder.  The  burst  and  3t  disk  discharging  spores;  4,  disk  with 
empty  sacs  are  whitish,  and  hang  sPore'sacs • 

around  the  discs  in  torn  scallops,  after  the  spores  are  shed.  The  spores, 
when  seen  under  the  microscope,  are  wonderful  objects,  each  a little 
green  ball  with  four  spiral  bands  wound  about  it.  These  spirals  uncoil 
and  throw  the  spore,  giving  it  a movement  as  of  something  alive.  The 
motor  power  in  these  living  springs  is  the  absorbing  of  moisture. 

The  beginning  of  the  sterile  shoot  can  be  seen  like  a green  bit  of  the 
blossom  spike  of  the  plantain;  but  later,  after  the  fertile  stalks  have 
died  down,  these  cover  the  ground  with  their  strange  fringes. 

The  person  who  first  called  these  sterile  plants  “horsetails”  had  an 
overworked  imagination,  or  none  at  all ; for  the  only  quality  the  two  have 
in  common  is  brushiness.  A horse  which  had  the  hair  of  its  tail  set  in 
whorls  with  the  same  precision  as  this  plant  has  its  branches  would  be  one 
of  the  world’s  wonders.  The  Equicetum  is  one  of  the  plants  which  give 
evidence  of  nature’s  resourcefulness;  its  remote  ancestors  probably  had  a 
whorl  of  leaves  at  each  joint  or  node  of  the  main  stem  and  branches ; but 
the  plant  now  having  so  many  green  branches,  does  not  really  need  the 
leaves,  and  thus  they  have  been  reduced  to  mere  points,  and  look  like

nothing  but  “trimming,”  they  are  so  purely  ornamental.'  Each  little  cup 
or  socket,  of  the  joint  or  node,  in  branch  or  stem,  has  a row  of  points 
around  its  margin,  and  these  points  are  terminals  of  the  angles  in  the 
branch.  If  a branch  is  triangular  in  cross  section,  it  will  have  three 
points  at  its  socket,  if  quadrangular  it  will  have  four  points,  and  the  main 

stem  may  have  six  or  a dozen, 
or  even  more  points.  The 
main  stem  and  branches  are 
made  up  entirely  of  these  .seg- 
ments, each  set  at  its  lower  end 
in  the  socket  of  the  segment  be- 
hind or  below  it.  These  green 
branches,  rich  in  chlorophyl, 
manufacture  for  the  plant  all  the 
food  that  it  needs.  Late  in  the 
season  this  food  is  stored  in 
the  rootstocks,  so  that  early  next 
spring  the  fertile  plants,  nour- 
ished by  this  stored  material,  are 
able  to  push  forth  before  most 
other  plants,  and  thus  develop 
their  spores  early  in  the  season. 
There  is  a prothallium  stage  as 
in  the  ferns. 

Above  where  the  whorl  of 
stems  comes  from  the  main 
branch,  may  be  seen  a row  of 
upward-standing  points  which 
are  the  remnants  of  leaves ; each 
branch  as  it  leaves  the  stem  is  set 
in  a little  dark  cup  with  a toothed 
rim.  There  is  a nice  gradation 
from  the  stout  lower  part  of  the 
stem  to  the  tip,  which  is  as  deli- 
cate as  one  of  the  side  branches. 
The  rootstock  dies  out  behind 
the  plant  and  pushes  on  ahead  like  the  rootstock  of  ferns.  The  true 
roots  may  be  seen  attached  on  the  under  side.  The  food  made  in  the 
summer  is  stored  in  little  tubers,  which  may  be  seen  in  the  rootstocks.

LESSON  CLXXVII 
The  Field  Horsetail 
The  Fertile  Plant 

Leading  thought — The  horsetail  is  a plant  that  develops  spores  instead 
of  seeds,  and  has  green  stems  instead  of  leaves. 

Method — In  April  and  May,  when  the  children  are  looking  for  flowers, 
they  will  find  some  of  these  weird  looking  plants.  These  should  be 
brought  to  the  schoolroom  and  the  observation  lesson  given  there. 

Observations — i.  Where  are  these  plants  found?  On  what  kind  of 
soil  ? 


Flowerless-Plant  Study 


701 


2.  In  what  respect  does  this  plant  differ  from  other  plants  in  appear- 
ance? Can  you  find  any  green  part  to  it? 

3.  What  color  is  the  stem?  Is  it  the  same  size  its  whole  length?  Is 
it  smooth  or  rough? 

4.  Do  you  see  any  leaves  on  the  stems?  Do  you  see  the  black- 
pointed  scales?  In  which  direction  do  these  scales  point?  Are  they 
united  at  the  bottom?  What  sort  of  a ring  do  they  make  around  the 
stem?  Split  a stem  lengthwise  and  see  if  there  are  joints,  or  nodes,  where 
the  ring  joins  the  stalk. 

5.  How  does  the  “blossom”  look?  What  color  are  the  little  discs 
that  make  up  the  blossom?  How  are  the  discs  set? 

6.  Take  one  of  the  plants  which  has  the  discs  surrounded  by  green 
ridges.  Shake  it  over  a white  paper.  What  comes  from  it  ? Where  does 
it  come  from?  Which  discs  on  the  stalk  shed  the  green  spores  first? 

The  Sterile  Plants 

Leading  thought — The  horsetail  or  Equicetum  is  nourished  by  very  dif- 
ferent looking  stems  than  those  which  bore  the  spores.  It  lacks  leaves, 
but  its  branches  are  green  and  do  the  work  of  making  food  for  the  plant. 

Method — The  sterile  plants  of  the  horsetail  do  not  appear  for  several 
weeks  after  the  fertile  ones;  they  are  much  more  numerous,  and  do  not 
resemble  the  fertile  plants  in  form  or  color.  These  sterile  plants  may  be 
used  for  a lesson  in  September  or  October.  Some  of  these  plants  with 
their  roots  may  be  brought  into  the  schoolroom  for  study. 

Observations — 1.  Has  this  plant  any  leaves?  How  does  it  make  and 
digest  its  food  without  leaves?  What  part  of  it  is  green?  Wherever 
there  is  green  in  a plant,  there  is  the  chlorophyl-factory  for  making  food.. 
In  the  horsetail,  then,  what  part  of  the  plant  does  the  work  of  leaves? 

2.  Take  off  one  little  branch  and  study  with  the  lens.  How  does  it 
look  ? Pull  it  apart  ? Where  does  it  break  easily  ? How  many  j oints,  or 
nodes,  are  there  in  the  branch? 

3 . Study  the  socket  from  which  one  of  the  segments  was  pulled  off. 
What  do  you  see  around  its  edge  ? How  many  of  these  points  ? Look  at 
the  branch  in  cross  section.  How  many  angles  has  it  ? What  relation  do 
the  points  bear  to  the  angles  ? Do  you  think  these  points  are  all  there  are 
left  of  true  leaves? 

4.  How  do  the  little  green  branches  come  off  the  main  stem?  How 
many  in  a place  ? How  many  whorls  of  branches  on  the  main  stem  ? 

5.  Study  the  bases  of  the  branches.  What  do  you  see?  Look 
directly  above  where  the  whorl  of  branches  comes  off  the  main  stem. 
What  do  you  see?  Cut  the  main  stem  in  cross-section  just  below  this 
place,  and  see  if  there  are  as  many  little  points  as  there  are  angles,  or 
ridges,  in  the  stem.  Do  you  suppose  these  little  points  are  the  remnants 
of  leaves  on  the  main  stem  ? 

6.  What  kind  of  root  has  the  horsetail?  Do  you  think  this  long 
running  root  is  the  true  root  or  an  underground  stem?  Where  are  the 
true  roots?  Do  you  think  the  rootstock  dies  off  at  the  oldest  end  each 
year,,  like  the  fern  ? Can  you  find  the  little  tubers  in  the  rootstock,  which 
contain  nourishment  for  next  year’s  spore-bearing  stalks?

THE  HAIR-CAP  MOSS.  OR  PIGEON  WHEAT 


The  mosses  are-  a 
special  delight  to 
children  because  they 
are  green  and  beauti- 
ful before  other  plants 
have  gained  their 
greenness  in  the  spring 
and  after  they  have 
lost  it  in  the  fall;  to 
the  discerning  eye,  a 
mossy  bankor  a mossy 
log  is  a thingof  beauty 
always.  When  we 
were  children  we  re- 
garded moss  as  a 
forest  for  fairy  folk, 
each  moss  stem  being 
a tree,  and  we  natural- 
ly concludedthat  fairy 
forests  were  evergreen. 
We  also  had  other 
diversions  with  pigeon 
wheat,  for  we  took 
the  fruiting  stem, 
pulled  the  cap  off  the  spore-capsule,  tucked  the  other  end  of  the  red  stem 
into  the  middle  of  the  capsule,  making  a beautiful  coral  ring  with  an 
emerald  “set.”  To  be  sure  these  rings  were  rather  too  delicate  to  last 
long,  but  there  were  plenty  more  to  be  had  for  nothing;  so  we  made  these 
rings  into  long  chains  which  we  wore  as  necklaces  for  brief  and  happy 
moments,  their  evanescence  being  one  of  their  charms. 

Pigeon  wheat  is  a rather  large  moss  which  grows  on  dry  knolls,  usually 
near  the  margins  of  damp  woodlands  in  just  those  places  where  winter- 
greens  love  to  grow.  In  fall  or  winter  it  forms  a greenish  brown  mass  of 
bristling  stems;  in  the  early  summer  the  stems  are  tipped  with  the  vivid 
green  of  the  new  growth.  The  bristling  appearance  comes  from  the  long 
sharp  leaves  set  thickly  upon  the  ruddy  brown  stems;  each  leaf  is  pretty 
to  look  at  with  a lens,  which  reveals  it  as  thick  though  narrow,  grooved 
along  the  middle,  the  edges  usually  armed  with  sharp  teeth  and  the  base 
clasping  the  stem.  These  leaves,  although  so  small,  are  wonderfully 
made ; during  the  hot,  dry  weather  they  shut  up  lengthwise  and  twist  into 
the  merest  threads,  in  order  to  keep  their  soft,  green  surfaces  from  losing 
their  moisture  by  exposure  to  the  air ; more  than  this,  they  lift  themselves 
and  huddle  close  to  the  stem,  and  are  thus  as  snug  and  safe  as  may  be  from 
the  effect  of  drought ; but  as  soon  as  the  rains  come,  they  straighten  back 
at  right  angles  to  the  stem,  and  curve  their  tips  downward  in  a joyful 
expanding.  Bring  in  some  of  this  moss  and  let  it  dry,  and  then  drop  it 
into  a glass  of  water  and  watch  this  miracle  of  leaf  movement ! And  yet 
it  is  no  miracle  but  a mechanism  quite  automatic — and  therefore — like 
other  miracles,  when  once  they  are  understood.

In  early  June  the  mossy  knoll  shows  us  the  origin  of  the  name  pigeon 
grass  or  pigeon  wheat,  for  it  is  then  covered  with  a forest  of  shining,  ruddy, 
stiff,  little  stems,  each  stem  bearing  on  its  tip  a woolly  object  about  the

size  of  a grain  of  wheat.  But  it  is  safe  to  say  that  the  pigeons  and  other 
birds  enjoy  our  own  kind  of  wheat  better  than  this,  which  is  attributed  to 
them. 

A study  of  one  of  these  wheat  grains  reveals  it  as  covered  with  a yellow- 
ish, mohair  cap,  ending  in  a golden  brown  peak  at  its  tip,  as  if  it  were  the 
original  pattern  of  the  toboggan  cap;  it  closes  loosely  and  downily 
around  the  stem  below.  This  grain  is  the  spore-capsule  of  the  moss;  the 
hairy  cap  pulls  off  easily  when  seized  by  its  tip.  This  cap  is  present  at  the 
very  beginning,  even  before  the  stem  lengthens,  to  protect  the  delicate 
tissues  of  the  growing  spore-case ; it  is  only  through  a lens  that  we  can 
see  it  in  all  its  silky  softness.  The  capsule  revealed  by  the  removal  of  the 
cap  is  a beautiful  green  object,  usually  four-sided,  set  upon  an  elegant 
little  pedestal  where  it  joins  the  coral  stem,  and  with  a lid  on  its  top  like  a 
sugar-bowl  cover,  with  a point  instead  of  a knob  at  its  center.  When  the 
spores  are  ripe,  this  lid  falls  off,  and  then  if  we  have  a lens  we  may  see 
another  instance  of  moss  mechanism.  Looking  at  the  uncovered  end  of 
the  capsule,  we  see  a row  of  tiny  teeth  around  the  margin,  which  seem  to 
hold  down  an  inner  cover  with  a little  raised  rim.  The  botanists  have 
counted  these  teeth  and  find  there  are  64.  The  teeth  themselves  are  not 
important,  but  the  openings  between  them  are,  since  only  through  these 
openings  can  the  spores  escape.  In  fact,  the  capsule  is  a pepper-box  with 
a grating  around  its  upper  edge  instead  of  holes  in  its  cover ; and  when  it 
is  fully  ripe,  instead  of  standing  right  side  up,  it  tips  over  so  as  to  shake 
out  its  spores  more  easily.  These  teeth  are  like  the  moss  leaves;  they 
swell  with  moisture,  and  thus  in  rainy  weather  they,  with  the  inner  cover, 
swell  so  that  not  a single  spore  can  be  shaken  out.  If  spores  should  come 
out  during  the  rain,  they  would  fall  among  the  parent  plants  where  there 
is  no  room  for  growth.  But  when  they  emerge  in  dry  weather,  the  wind 
scatters  them  far  and  wide  where  there  is  room  for  development. 

When  seen  with  the  naked  eye,  the  spores  seem  to  be  simply  fine  dust, 
but  each  dust  grain  is  able  to  produce  moss  plants.  However,  the  spore 
does  not  grow  up  into  a plant  like  a seed,  it  grows  into  fine,  green,  branch- 
ing threads  which  push  along  the  surface  of  damp  soil;  on  these  threads 
little  buds  appear,  each  of  which  grows  up  into  a moss  stem. 

The  spore-capsule  is  hardly  the  fruit  of  the  moss  plant.  If  we  examine 
the  moss,  we  find  that  some  stems  end  in  yellowish  cups  which  look  almost 
like  blossoms;  on  closer  examination,  we  find  that  there  are  several  of 
these  cups,  one  below  the  other,  with  the  stem  extending  up  through  the 
middle.  The  upp^r  cup  matured  this  year,  the  one  below  it  last  year,  and 
so  on.  These  cups  are  star-pointed,  and  inside,  at  the  bottom,  is  a starlike 
cluster  of  leaves.  Among  the  leaves  of  this  star-rosette  are  borne  the 
moss  anthers  called  antheridii,  too  small  for  us  to  see  without  a high 
power  microscope.  The  pollen  from  these  anthers  is  blown  over  to  other 
plants,  some  of  which  produce  ovules  at  their  very  tips,  although  the 
ovule  has  no  leaf-rosette  to  show  where  it  is.  This  ovule,  after  receiving 
the  pollen,  grows  into  the  spore-capsule  supported  on  its  coral  stem. 
These — stem,  capsule  and  all — grow  up  out  of  the  mother  plant,  the  red 
stem  is  enlarged  at  its  base,  and  fits  into  the  moss  stem  like  a flagstaff  in 
the  socket.  After  the  star-shaped  cup  has  shed  its  pollen,  the  stem  grows 
up  from  its  center  for  an  inch  or  so  in  height  and  bears  new  leaves,  and 
next  year  will  bear  another  starry  cup. 


Flowerless-Plant  Study

The  brown  leaves  on  the  lower  part  of  the  moss  stem  are  dead,  and 
only  the  green  leaves  on  the  upper  part  are  living. 

And  this  is  the  story  of  the  moss  cycle : 

1.  A plant  with  an  ovule  at  its  tip;  another  plant  with  a star-cup 
holding  the  moss  pollen  which  is  sifted  by  wind  over  to  the  waiting  egg. 

2.  The  egg  or  ovule  as  soon  as  fertilized  develops  into  a spore-capsule, 
and  is  lifted  up  into  the  world  on  a beautiful  shining  stem  and  is  pro- 
tected by  a silky  cap. 

3 . The  cap  comes  off ; the  lid  of  the  spore-case  falls  off,  the  spores  are 
shaken  out  and  scattered  by  the  wind. 

4.  Those  spores  that  find  fitting  places  grow  into  a net  of  green 
threads. 

5.  These  green  threads  send  up  moss  stems  which  repeat  the  story. 

LESSON  CLXXVIII 
The  Hair-Cap  Moss 

Leading  thought — The  mosses,  like  the  butterfly  and  the  fern,  have 
several  stages  in  their  development.  The  butterfly  stages  are  the  egg, 
the  caterpillar,  the  chrysalis,  the  butterfly.  The  moss  stages  are  the  egg 
(or  ovule),  the  spores,  the  branching  green  threads,  the  moss  plants  with 
their  green  foliage.  In  June  we  can  easily  find  all  these  stages,  except 
perhaps  the  branching  thread  stage. 

Method — The  children  should  bring  to  the  schoolroom  a basin  of  moss 
in  its  fruiting  stage ; or  still  better,  go  with  them  to  a knoll  covered  with 
moss.  Incidentally  tell  them  that  this  moss,  when  dried,  is  used  by  the 
Laplanders  for  stuffing  their  pillows,  and  that  the  bears  use  it  for  their 
beds.  Once,  a long  time  ago,  people  believed  that  a plant,  by  the  shape  of 
its  leaf  or  flower,  indicated  its  nature  as  a medicine,  and  as  this  moss 
looked  like  hair,  the  water  in  which  it  was  steeped  was  used  as  a hair 
tonic. 

Observation — 1 . Take  a moss  stem  with  a grain  of  pigeon  wheat  at  the 
end.  Examine  the  lower  part  of  the  stalk.  How  are  the  leaves  arranged 
on  it?  Examine  one  of  the  little  leaves  through  a lens  and  describe  its 
shape,  its  edges,  and  the  way  it  joins  the  stem.  Are  the  lower  leaves  the 
same  color  as  the  upper  ones  ? Why  ? 

2.  Describe  the  pretty  shining  stem  of  the  fruit,  which  is  called  the 
pedicel.  Is  it  the  same  color  for  its  entire  length  ? Can  you  pull  it  easily 
from  the  main  plant  ? Describe  how  its  base  is  embedded  in  the  tip  of  the 
plant. 

3.  Note  the  silken  cap  on  a grain  of  the  pigeon  wheat.  This  is  called 
the  veil.  Is  it  all  the  same  color?  Is  it  grown  fast  to  the  plant  at  its 
lower  margin?  Take  it  by  the  tip,  and  pull  it  off.  Is  this  done  easily? 
Describe  what  it  covers.  This  elegant  little  green  vase  is  called  a spore- 
capsule.  How  many  sides  has  it?  Describe  its  base  which  stands  upon 
the  stem.  Describe  the  little  lid.  Pull  off  the  lid;  is  there  another  lid 
below  it?  Can  you  see  the  tiny  teeth  around  the  edge  which  hold  this 
lid  in  place?  Ask  your  teacher,  or  read  in  the  books,  the  purpose  of  this. 

4.  Do  all  the  spore  vases  stand  straight  up,  or  do  some  bend  over? 

- 5.  Do  you  think  the  silken  cap  falls  off  of  itself  after  a while?  Can 
you  find  any  capsules  where  the  cap  or  veil  and  the  lid  have  fallen  off? 
See  if  you  can  shake  any  dust  out  of  such  a spore  vase.  What  do  you 


706 


Handbook  of  Nature-Study 


think  this  dust  is?  Ask  your  teacher,  or  read  in  the  books,  about  moss 
spores  and  what  happens  if  they  find  a damp  place  in  which  to  grow. 

6.  Hunt  among  the  moss  for  some  stems  that  have  pretty,  yellowish, 
starlike  cups  at  their  tips.  How  does  the  inside  of  one  of  these  cups  look? 
Ask  the  teacher  to  tell  you  what  grows  in  this  cup.  Look  down  the  stem 
and  see  if  you  can  find  last  year’s  cup.  The  cup  of  two  years  ago? 
Measured  by  these  cups  how  old  do  you  think  this  moss  stem  is? 

7 . Select  some  stems  of  moss,  both  those  that  bear  the  fruit  and  those 
that  bear  the  cups.  After  they  are  dried  describe  how  the  leaves  look. 
Examine  the  plant  with  a lens  and  note  how  these  leaves  are  folded  and 
twisted.  Do  the  leaves  stand  out  from  the  stem  or  lie  close  to  it  ? Is  this 
action  of  the  leaves  of  any  use  to  the  plant  in  keeping  the  water  from 
evaporating ? How  do  the  star-cups  look  when  dry  ? 

8.  Place  these  dried  stems  in  a glass  of  water  and  describe  what  hap- 
pens to  the  cup.  Examine  some  of  the  dried  moss  and  the  wet  moss  with 
a lens,  and  describe  the  difference.  Of  what  use  to  the  moss  is  this  power 
of  changing  form  when  damp  ?

MUSHROOMS  AND  OTHER  FUNGI 
Teacher's  Story 

HERE  is  something  uncanny  about  plants  which 
have  no  green  parts ; they  seem  like  people  with- 
out blood.  It  is;  therefore,  no  wonder  that  many 
superstitions  cluster  about  toadstools.  In  times 
of  old,  not  only  did  the  toads  sit  on  them,  but 
fairies  danced  upon  them  and  used  them  for 
umbrellas.  The  poisonous  qualities  of  some 
species  made  them  also  a natural  ingredient  of 
the  witch’s  cauldron.  But  science,  in  these  days, 
brings  revelations  concerning  these  mysterious 
plants  which  are  far  more  wonderful  than  the 
web  which  superstition  wove  about  them  in  days 
of  yore. 

■ When  we  find  plants  with  no  green  parts  which  grow  and  thrive, 
though  unable  to  manufacture  their  own  organic  food  through  the  alchemy 
of  chlorophyl,  sunlight  and  air,  we  may  safely  infer  that  in  one  way  or 
another  they  gain  the  products  of  this  alchemy  at  second  hand.  Such 
plants  are  either  parasites  or  saprophytes;  if  parasites,  they  steal  the 
food  from  the  cells  of  living  plants;  if  saprophytes,  they  live  on  such  of 
this  food  material  as  remains  in  dead  wood,  withered  leaves,  or  soils 
enriched  by  their  remains. 

Thus,  we  find  mushrooms  and  other  fungus  fruiting  bodies,  pallid, 
brown -olive,  yellow  or  red  in  color,  but  with  no  signs  of  the  living  green 
of  other  plants ; and  this  fact  reveals  their  history.  Some  of  them  are 
parasites,  as  certain  species  of  bracket  fungi  which  are  the  deadly  enemies 
of  living  trees;  but  most  of  the  fungus  species  that  we  ordinarily  see 
are  saprophytes,  and  live  on  dead  vegetation.  Fungi,  as  a whole,  are  a 
great  boon  to  the  world.  Without  them  our  forests  would  be  choked 


Flowerless-Plant  Study 


7°7 


out  with  dead  wood.  Decay  is  simply  the  process  by  which  fungi  and  other 
organisms  break  down  dead  material,  so  that  the  major  part  of  it  returns 
to  the  air  in  gaseous  form,  and  the  remainder,  now  mostly  humus,  mingles 
with  the  soil. 

As  a table  delicacy,  mushrooms  are  highly  prized.  A very  large  num- 
ber of  species  are  edible.  But  every  year  the  newspapers  report  deaths 
resulting  from  eating  the  poisonous  kinds — the  price  of  an  ignorance  which 
comes  from  a lack  of  the  powers  of  observation  developed  in  nature-study. 
It  would  be  very  unwise  for  any  teacher  to  give  rules  to  guide  her  pupils  in 
separating  edible  from  poisonous  mushrooms,  since  the  most  careful  direc- 
tions may  be  disregarded  or  misunder- 
stood. She  should  emphasize  the  danger 
incurred  by  mistaking  a poisonous  for  an 
edible  species.  One  small  button  of  the 
deadly  kind,  if  eaten,  may  cause  death. 

A few  warning  rules  may  be  given,  which 
if  firmly  impressed  on  the  pupils,  may 
result  in  saving  human  life. 

First  and  most  important,  avoid  all 
mushrooms  that  are  covered  with  scales, 
or  that  have  the  base  of  the  stem  included 
in  a sac,  for  two  of  the  poisonous  species, 
often  mistaken  for  the  common  edible 
mushroom,  have  these  distinguishing 
characters.  Care  should  be  taken  that 
every  specimen  be  collected  in  a way  to 
show  the  base  of  the  stem,  since  in  some 
poisonous  species  this  sac  is  hidden  be- 
neath the  soil. 

Second,  avoid  the  young,  or  button, 
stages,  since  they  are  similar  in  appear- 
ance in  species  that  are  edible  and  in 
those  that  are  poisonous. 

Third,  avoid  those  that  have  milky 
juices;  unless  the  juices  are  reddish  in 
color,  the  mushrooms  should  not  be 
eaten. 

Fourth,  avoid  those  with  shiny,  thin, 
or  brightly  colored  caps,  and  those  with 
whitish  or  clay-colored  spores. 

Fifth,  no  mushroom  or  puffball  should  be  eaten  after  its  meat  has 
begun  to  turn  brown  or  has  become  infested  with  fly  larvae.

How  Mushrooms  Look  and  How  They  Live 

HERE  are  many  kinds  of  mushrooms  varying  greatly  in  form, 
color  and  size,  but  wherever  they  appear  it  means  that 
sometime  previous  the  mushroom  spores  have  been 
planted  there.  There  they  threw  out  threads  which  have 
penetrated  the  food  substance  and  gained  a successful 
growth,  which  finally  resulted  in  sending  up  into  the  world 
the  fruiting  organs.  In  general  shape  these  consist  of  a stem  with  a cap 
upon  it,  making  it  usually  somewhat  umbrella-shaped.  Attached  to  the

cap  and  usually  under  it,  are  plate-like  growths  called  gills,  or  a fleshy 
surface  which  is  full  of  pores.  In  the  case  of  the  gills,  each  side  of  each

plate  develops  spores, 
other  mushrooms. 


These,  as  fine  as  dust,  are  capable  of  producing 


In  the  common  edible  species  of 
mushroom  ( Agaricus  campestris),  the 
stem  is  white  and  almost  cylindrical, 
tapering  slightly  toward  the  base;  it  is 
solid  although  the  core  is  not  so  firm  as 
the  outside.  When  it  first  pushes  above 
the  ground,  it  is  in  what  is  called  the 
“button  stage”  and  consists  of  a little, 
rounded  cap  covered  with  a membrane 
which  is  attached  to  the  stem.  Later 
the  cap  spreads  wide,  for  it  is  naturally 
umbrella-shaped,  and  it  tears  loose  this 
membrane,  leaving  a piece  of  it  attached 
to  the  stem;  this  remnant  is  called  the 
ring  or  collar.  The  collar  is  very  notice- 
able in  many  species,  but  in  the  common 
mushroom  it  soon  shrivels  and  disap- 
pears. The  cap  is  at  first  rounded  and 
then  convex;  its  surface  is  at  first 
smooth,  looking  soft  and  silky;  but  as 
the  plant  becomes  old,  it  is  often  broken 
up  into  triangular  scales  which  are  often 
dark  brown;  although  the  color  of  the 
cap  is  usually  white  or  pale  brown.  The 
gills  beneath  the  cap  are  at  first  white, 
but  later,  as  the  spores  mature,  they  be- 
come brownish  black  because  of  the 
ripened  spores.

LESSON  CLXXIX 
Mushrooms 

Leading  thought — Mushrooms  are  the  fruiting  organs  of  the  fungi  which 
grow  in  the  form  of  threads,  spreading  in  every  direction  through  the  food 
material.  The  dust  which  falls  from  ripe  mushrooms  is  made  up  of 
spores  which  are  not  true  seeds,  but  which  will  start  a new  growth  of  the 
fungus. 

Method — The  ideal  method  would  be  to  study  the  mushrooms  in  the 
field  and  forest,  making  an  excursion  for  the  purpose  of  collecting  as  many

species  as  possible.  But  the  lesson  may  be  given  from  specimens  brought 
into  the  schoolroom  by  pupils,  care  being  taken  to  bring  with  them  the 
soil,  dead  wood  or  leaves  on  which  they  were  found  growing.  After 
studying  one  species  thus,  encourage  the  pupils  to  bring  in  as  many  others 
as  possible.  There  are  a few  terms  which  the  pupils  should  learn  to  use, 
and  the  best  method  of  teaching  them  is  to  place  the  diagrams  shown  on 
pages 708,  7 11,  712,  on  the  blackboard,  and  leave  them  therefor  a time. 

Since  mushrooms  are  especially  good  subjects  for  water-color  and 
pencil  studies,  it  would  add  much  to  the  interest  of  the  work  if  each  pupil, 
or  the  school  as  a whole,  should  make  a portfolio  of  sketches  of  all  the 
species  found . With  each  drawing  there  should  be  made  on  a supplemen- 
tary sheet  a spore-print  of  the  species.  White  paper  should  be  covered

very  thinly  with  white  of  egg  or  mucilage,  so  as  to  hold  fast  the  discharged 
spores  when  making  these  prints  for  portfolio  or  herbarium. 

Observations — i.  Where  was  the  mushroom  found?  If  on  the 
ground,  was  the  soil  wet  or  dry?  Was  it  in  open  fields  or  in  woods?  Or 
was  it  found  on  rotten  wood,  fallen  leaves,  old  trees  or  stumps,  or  roots? 
Were  there  many  or  few  specimens? 

2.  Is  the  cap  cone-shaped,  bell-shaped,  convex,  plane,  concave,  or 
funnel-form?  Has  it  a raised  point  at  the  center?  How  wide  is  it? 

3.  What  is  the  color  of  the  upper  surface  of  the  cap  when  young? 
When  old  ? Has  it  any  spots  of  different  colors  on  it  ? Has  it  any  striate 
markings,  dots  or  fine  grains  on  its  surface?  Is  its  texture  smooth  or 
scaly?  Is  its  surface  dull,  or  polished,  or  slimy?  Break  the  cap  and  note 
the  color  of  the  juice.  Is  it  milky  ? 

4.  Look  beneath  the 
cap.  Is  the  under  surface 
divided  into  plates  like 
the  leaves  of  a book,  or  is 
it  porous  ? 

5.  The  plates  which 
may  be  compared  to  the 
leaves  of  a book  are  called 
gills,  although  they  are 
not  for  the  purpose  of 
breathing,  as  are  the  gills 
of  a fish.  Are  there  more 
gills  near  the  edge  of  the 
cap  than  near  the  stem? 
How  does  this  occur? 
What  are  the  colors  of  the 
gills?  Are  the  gills  the 
same  color  when  young  as 
when  old  ? Are  the  lower 
edges  of  the  gills  sharp, 
blunt  or  saw-toothed  ? 

6.  Break  off  a cap  and

do  not  join  the  stem  at  all  they  are  termed  “free.”  If  they  end  by  being 
joined  to  the  stem,  they  are  called  “adnate”  or  “adnexed.”  If  they 
extend  down  the  stem  they  are  called  “decurrent.” 

7.  Take  a freshly  opened  mushroom,  cut  off  the  stem,  even  with  the 
cap,  and  set  the  cap,  gills  down,  on  white  paper;  cover  with  a tumbler,  or 
other  dish  to  exclude  draught;  leave  it  for  twenty-four  hours  and  then 
remove  the  cover,  lift  the  cap  carefully  and  examine  the  paper.  What 
color  is  the  imprint?  What  is  its  shape?  Touch  it  gently  with  a pencil 
and  see  what  makes  the  imprint.  Can  you  tell  by  the  pattern  where  this 
fine  dust  came  from  ? Examine  the  dust  with  a lens.  This  dust  is  made 
up  of  mushroom  spores,  which  are  not  true  seeds,  but  which  do  for  mush- 
rooms what  seeds  do  for  plants.  How  do  you  think  the  spores  are 
scattered?  Do  you  know  that  one  little  grain  of  this  spore  dust  would 
start  a new  growth  of  mushrooms?

8.  Look  at  the  stem.  What  is  its  length ? Its  color?  Is  it  slender 
or  stocky?  Is  its  surface  shiny,  smooth,  scaly,  striate  or  dotted?  Has  it 
a collar  or  ring  around  it  near  the  top  ? What  is  the  appearance  of  this 
ring?  Is  it  fastened  to  the  stem,  or  will  it  slide  up  and  down?  Is  the 
stem  solid  or  hollow?  Is  it  swollen  at  its  base?  Is  its  base  set  in  a sac.  or 
cup,  or  is  it  covered  with  a membrane  which  scales  off?  Do  you  know 
that  the  most  poisonous  of  mushrooms  have  the  sac  or  the  scaly  covering 
at  the  base  of  the  stem? 

9.  Examine  with  a lens  the  material 
on  which  the  mushroom  was  growing; 
do  you  see  any  threads  in  it  that  look 
like  mold?  Find  if  you  can  what  these 
threads  do  for  the  mushroom?  If  you 
were  to  go  into  the  mushroom  business

PUFFBALLS 
Teacher's  Story 

The  puffballs  are  always  interesting  to  children,  because  of  the  ‘ ‘smoke” 
which  issues  from  them  in  clouds  when  they  are  pressed  between  thumb 
and  finger.  The  common  species  are  white  or  creamy  when  young ; and 
some  of  the  species  are  warty  or  roughened,  so  that  as  children  we  called 
them  “little  lambs.”  They  grow  on  the  ground  usually,  some  in  wet, 
shady  places,  and  others,  as  the  giant  species,  in  grassy  fields  in  late 
summer.  This  giant  puffball  always  excites  interest,  when  found.  It  is 
a smoothish,  white,  rounded  mass,  apparently  resting  on  the  grass  as  if 
thrown  there ; when  lifted  it  is  seen  that  it  has  a connection  below  at  its 
center,  through  its  mycelium  threads,  which  form  a network  in  the  soil. 
It  is  often  a foot  in  diameter,  and  specimens  four  feet  through  have  been 
recorded.  When  its  meat  is  solid  and  white  to  the  very  center,  it  makes 
very  good  food.  The  skin  should  be  pared  off,  the  meat  sliced  and 
sprinkled  with  salt  and  pepper  and  fried  in  hot  fat  until  browned.  All 
the  puffballs  are  edible,  but  ignorant  persons  might  mistake  the  button 
stages  of  some  of  the  poisonous  mushrooms  for  little  puffballs,  and  it  is  not 
well  to  encourage  the  use  of  small  puffballs  for  the  table. 


Flowerless-Plant  Study 


A common  species — “the  beaker  puffball”  is  pear-shaped,  with  its 
small  end  made  fast  to  the  ground,  which  is  permeated  with  its  vegetative 
threads. 

The  interior  of  a puffball,  “the 
meat,”  is  made  up  of  the  threads  and 
spores.  As  they  ripen,  the  threads 
break  up  so  that  with  the  spores  they 
make  the  “smoke,”  as  can  be  seen  if 
the  dust  is  examined  through  a micro- 
scope. The  outer  wall  may  become 
dry  and  brittle  and  break  open  to 
allow  the  spores  to  escape,  or  one  or 
more  openings  may  appear  in  it  as 
spore  doors.  The  spores  of  puffballs 
were  used  extensively  in  pioneer  days 
to  stop  the  bleeding  of  wounds  and 
especially  for  nosebleed.

lengthwise  in  six  or  seven  sections  but  still  remaining  attached  to  the  base. 
There  is  an  inner  coat  that  remains  as  a protection  to  the  spores,  so  that 
these  little  balls  are  set  each  in  a little  star-shaped  saucer.  These  star 
points  straighten  out  flat  or  even  curl  under  in  dry  Weather,  but  when 
damp  they  lift  up  and  again  envelop  the  ball  to  a greater  or  less  extent.

Puffballs 


Photo  by  Verne  Morton 


Leading  thought — 
The  puffballs  are 
fungi  that  grow  from 
the  threads,  or  my- 
celium, which  per- 
meate the  ground  or 
other  matter  on 
which  the  puffballs 
grow.  The  puffballs 
are  the  fruiting  or- 
gans, and  “smoke” 
which  issues  from 
them  is  largely 
made  up  of  spores, 
which  are  carried  off 
by  the  wind  and 
sown  and  planted. 

Method — Ask  the 
pupils  to  bring  to 
school  any  of  the 
globular  or  pear- 
shaped  fungi  in  the 
early  stages  when

they  are  white,  taking  pains  to  bring  them  on  the  soil  or  wood  on  which 
they  are  growing. 

Observations — i.  Where  did  you  find  the  puffball?  On  what  was  it 
growing  ? W ere  there  many  growing  in  company  ? Remove  the  puffball, 
and  examine  the  place  where  it  stood  with  a lens  to  find  the  matted  and 
crisscrossed  fungus  threads. 

2.  What  is  the  size  and  shape  of  the  puffball  ? Is  its  surface  smooth 
or  warty?  What  is  its  color  inside  and  outside? 

3.  Have  you  ever  found  the  giant  puffball,  which  may  become  four 
inches  to  four  feet  through?  Where  was  it  growing?  Have  you  evei 
eaten  this  puffball  sliced  and  fried?  Do  you  know  by  the  looks  of  the 
meat  when  it  is  fit  to  eat? 

4.  If  the  puffball  is  ripe,  what  is  its  color  outside  and  in?  What  is 
the  color  of  its  “smoke?”  Does  the  smoke  come  out  through  the  broken 
covering  of  the  puffball,  or  are  there  one  or  more  special  openings  to  allow 
it  to  escape? 

5.  Puff  some  of  the  “smoke”  on  white  paper  and  examine  it  with  a 
lens.  What  do  you  think  this  dust  is?  Of  what  use  is  it  to  the  puffball ? 

6.  Have  you  ever  found  what  are  called  earth-stars,  which  look  like 
little  puffballs  set  in  star-shaped  cups?  If  you  find  these  note  the  follow- 
ing things : 

a.  Of  what  is  the  star-shaped  base  made?  Was  it  always  there? 

b.  Let  this  star  saucer  become  very  dry ; how  does  it  act  ? 

c.  Wet  it;  and  how  does  it  behave  then? 

d.  Where  and  how  does  the  spore  dust  escape  from  the  earth-stars  ? 

7.  For  what  medicinal  purpose  is  the  “smoke”  of  the  puffball  some- 
times used? 

THE  BRACKET  FUNGI 

Teacher's  Story 

There  are  some 
naturalistswhothink 
that  one  kind  of  life 
is  as  good  as  another 
and  therefore  call  all 
things  good.  Per- 
haps this  is  the  only 
true  attitude  for  the 
nature  lover.  To 
such  the  bracketlike 
fungi  which  appear 
upon  the  sides  of  our 
forest  and  shade 
trees  are  simply  an 
additional  beauty,  a 
bountiful  ornamen- 
tation. But  some  of 
us  have  become 
special  pleaders  in 
our  attitude  toward 
life,  and  those  of  us 
who  have  come  to

feel  the  grandeur  of  tree  life  can  but  look  with  sorrow  upon  these  fungus 
outgrowths,  for  they  mean  that  the  doom  of  the  tree  is  sealed. 

There  are  many  species  of  bracket  fungi.  Three  of  these  are  very 
common.  The  gray  bracket,  gray  above  and  with  creamy  surface  below 
(Polyporous  applanatus ) is  a favorite  for  amateur  etchers,  who  with  a 
sharp  point  make  interesting  sketches  upon  this  naturally  prepared  plate; 
this  species  often  grows  tc  great  size  and  is  frequently  very  old.  Another 
species  (P.  lucidus)  is  in  color  a beautiful  mahogany,  or  coral-red  above 
and  has  a peculiar  stem  from  which  it  depends;  the  stem  and  upper  sur- 
face are  polished  as  if  burnished  and  the  lower  surface  is  yellowish  white. 
Another  species  ( P . sulphur ens)  is  sulphur  yellow  above  and  below; 
usually  many  of  these  yellow  brackets  are  grouped  together,  their  fan- 
shaped caps  overlapping.  Many  of  the  shelf  fungi  live  only  on  dead  wood, 
and  those  are  an  aid  in  reducing  dead  branches  and  stumps  until  they 
crumble  and  become  again  a part  of  the  soil.  However,  several  of  the 
species  attack  living  trees  and  do  great  damage.  They  can  gain  access  to 
the  living  tree  only  through  an  injured  place  in  the  bark,  a break  caused 
perhaps  by  the  wind,  by  a bruise  from  a falling  tree,  or  more  often  from 
the  hack  of  the  careless  wood-chopper;  often  they  gain  entrance  through 
an  unhealed  knot-hole.  To  one  who  understands  trees  and  loves  them, 
their  patient  striving  to  heal  these  wounds  inflicted  by  forces  they  cannot 
withstand  is  truly  pathetic.  After  the  wound  is  made  and  before  the 
healing  is  accomplished,  the  wind  may  sift  into  the  wound  the  almost 
omnipresent  spores  of  these  fungi  and  the  work  of  destruction  begins. 
From  the  spores  grows  the  mycelium,  the  fungus  threads  which  push  into 
the  heart  of  the  wood  getting  nourishment  from  it  as  they  go.  When  we 
see  wood  thus  diseased  we  say  that  it  is  rotting,  but  rotting  merely  means 
the  yielding  up  of  the  body  substance  of  the  tree  to  these  voracious  fungus 
threads.  They  push  in  radially  and  then  grow  upward  and  downward, 
weakening  the  tree  where  it  most  needs  strength  to  withstand  the  on- 
slaught of  the  wind.  Later  these  parasitic  threads  may  reach  the  cam- 
bium layer,  the  living  ring  of  the  tree  trunk,  and  kill  the  tree  entirely ; but 
many  a tree  has  lived  long  with  the  fungus  attacking  its  heartwood.  A 
bracket  fungus  found  by  Professor  Atkinson  was  eighty  years  old ; how- 
ever, this  may  have  shortened  the  life  of  the  tree  a century  or  more. 

After  these  fungus  threads  are  thoroughly  established  in  the  tree,  they 
again  seek  a wound  in  the  protecting  bark  where  they  may  push  out  and 
build  the  fruiting  organ,  which  we  call  the  bracket.  This  may  be  at  the 
same  place  where  the  fatal  entry  was  made,  or  it  may  be  far  from  it.  The 
bracket  is  at  first  very  small  and  is  composed  of  a layer  of  honeycomb 
cells,  closed  and  hard  above  and  opening  below — cells  so  small  that  we  can 
see  the  cell  openings  only  with  a lens.  These  cells  are  not  hexagonal  like 
the  honeycomb,  but  are  tubes  packed  together.  Spores  are  developed  in 
each  tube.  Next  year  another  layer  of  cells  grows  beneath  this  first 
bracket  and  extends  out  beyond  it;  each  year  it  is  thus  added  to,  making 
it  thicker  and  marking  its  upper  surface  with  concentric  rings  around  the 
point  of  attachment.  The  creamy  surface  of  the  great  bracket  fungus  on 
which  etchings  are  made,  is  composed  of  a layer  of  these  minute  spore- 
bearing tubes.  Not  all  bracket  fungi  show  their  age  by  these  annual 
growths,  for  some  species -form  new  shelves  every  year,  which  decay  aftei 
the  spores  are  ripened  and  shed.

When  once  the  mycelium  of  such  fungus  becomes  established,  the  tree 
is  doomed  and  its  lumber  made  worthless  even  though,  as  sometimes 
happens,  the  tree  heals  its  wounds  so  that  the  fungus  is  imprisoned  and 
can  never  send  out  fruiting  brackets.  Thus  it  is  most  important  to  teach 
the  pupils  how  to  protect  trees  from  the  attacks  of  these  enemies,  which 
are  devastating  our  forests  and  which  sometimes  attack  our  orchards  and 
shade  trees. 

As  soon  as  a tree  is  bruised,  the  wound  should  be  painted  or  covered 
with  a coat  of  tar.  If  the  wind  breaks  a branch,  the  splinters  left  hanging 
should  be  sawed  off,  leaving  a smooth  stump,  and  this  be  painted.  While 
ordinary  paint  if  renewed  each  year  will  suffice,  experiment  has  shown 
that  the  coat  of  tar  is  better  and  should  be  used. 

Especially  should  teachers  impress  on  pupils  the  harm  done  by  careless 
hacking  with  axe  or  hatchet.  We  shall  do  an  invaluable  service  in  the 
protection  of  our  forests,  if  we  teach  the  rising  generation  the  respectful 
treatment  of  trees — which  is  due  living  organisms  whose  span  of  life  may 
cover  centuries. 

LESSON  CLXXXI 
Bracket  Fungi 

Leading  thought — The  fungi  which  we  see  growing  shelflike  from  trees, 
are  deadly  enemies  to  the  trees.  Their  spores  germinate  and  penetrate  at 
some  open  wound  and  the  growing  fungus  weakens  the  wood. 

Method — It  is  desirable  that  a tree  on  which  shelf  fungus  grows  should 
be  studied  by  the  class,  for  this  is  a lesson  on  the  care  of  trees.  After  this 
lesson  the  fungus  itself  may  be  studied  at  leisure  in  the  schoolroom. 

Observations — i.  On  what  kind  of  a tree  is  the  bracket  fungus  grow- 
ing ? Is  it  alive  or  dead  ? If  living,  does  it  look  vigorous  or  is  it  decaying  ? 

2 . Is  the  fungus  bracket  growing  against  the  side  of  the  tree,  or  does  it 
stand  out  on  a stem? 

3 . Look  at  the  place  where  the  bracket  joined  the  tree.  Does  it  seem 
to  be  a part  of  the  wood  ? 

4.  What  color  is  the  fungus  on  its  upper  surface?  How  large  is  it? 
How  thick  near  the  tree?  How  thick  at  the  edge?  Can  you  detect  con- 
centric layers  or  rings  ? If  it  is  the  large  species  used  for  etching,  cut  down 
through  it  with  a knife  or  hatchet  and  count  the  layers ; this  should  show 
its  age. 

5.  Look  at  the  lower  surface.  How  does  it  appear  to  the  naked  eye? 
If  you  scratch  it  with  a pin  or  knife  does  the  bruise  show?  Examine  the 
surface  with  a lens  and  describe  what  you  see.  Cut  or  break  the  fungus 
and  note  that  each  of  these  holes  is  an  opening  to  a little  tube.  In  each  of 
these  tubes  spores  are  borne. 

6.  Have  you  ever  seen  toadstools  that,  instead  of  having  the  leaflike 
gills,  have  beneath  the  cap  a porous  surface  like  a little  honeycomb  or  like 
the  under  side  of  the  shelf  fungi  ? 

7.  How  manv  kinds  of  shelf  fungi  can  you  find?  Which  of  them  is  on 
living  trees,  and  which  on  stumps  or  dead  wood? 

8.  If  the  fungus  is  on  a living  tree,  then  the  tree  is  ruined,  for  the 
fungus  threads  have  worked  through  it  and  weakened  it  so  that  it  will 
break  easily  and  is  of  no  use  as  lumber.  There  must  have  been  an  open 
wound  in  the  tree  where  the  fungus  entered ; see  whether  you  can  find  this

wound.  There  must  also  have  been  a wound  where  the  shelf  grew  out; 
see  whether  you  can  detect  it.  If  the  tree  should  heal  all  its  wounds  after 
the  fungus  entered,  what  would  become  of  the  fungus? 

9.  What  does  the  shelf  fungus  feed  on?  What  part  of  it  corresponds 
to  the  roots  and  leaves  of  other  plants?  What  part  may  be  compared  to 
the  flowering  and  fruiting  parts  of  plants  ? 

10.  What  treatment  must  we  give  trees  to  keep  them  free  from  this 

enemy  ? 


The  edible  Boletus  ( B . edulis).  This  has  tubes  below  the  cap  instead  of  gills. 

The  spores  are  developed  within  the  tubes , as  in  the  bracket  fungi.

LESSON  CLXXXII 
Hedgehog  Fungi 

There  is  something  mysterious  about  all  fungi,  but  perhaps  none  of 
these  wonderful  organisms  so  strangely  impresses  the  observer  as  the 
fountainlike  masses  c creamy  white  or  the  branching  white  coral  that  we 
see  growing  on  a dead  tree  trunk.  The  writer  remembers  as  a child  that 
the  finding  of  these  woodland  treasures  made  her  feel  as  if  she  were  in  the 
presence  of  the  supernatural,  as  if  she  had  discovered  a fairy  grotto  or  a 
kobold  cave.  The  prosaic  name  of  hedgehog  fungi  has  been  applied  to 
these  exquisite  growths.  Their  life  story  is  simple  enough.  The  spores 
falling  upon  dead  wood  start  threads  which  ramify  within  it  and  feed  on  its 
substance,  until  strong  enough  to  send  out  a fruiting  organ.  This  consists 
of  a stem,  dividing  into  ascending  branches ; from  these  branches,  depend- 
ing like  the  stalactites  in  a cave,  are  masses  of  drooping  spines,  the  surface 
of  each  bearing  the  spores.  And  it  is  so  natural  for  these  spines  to  hang 
earthward  that  they  are  invariably  so  placed  when  the  tree  is  in  the  posi-

tion  in  which  they  grew.  There  is  one  species  called  the  “satyr’s  beard,” 
sometimes  found  on  living  trees,  which  is  a mere  bunch  of  downward- 
hanging spines ; the  corallike  species  is  called  Hydnum  coraloides,  and  the 
one  that  looks  like  an  exquisite  white  frozen  fountain,  and  maybe  seen  in 
late  summer  or  early  autumn  growing  from  dead  limbs  or  branches,  is  the 
bear’s  head  fungus;  it  is  often  eight  inches  across. 

Observations — i.  These  fungi  come  from  a stem  which  extends  into 
the  wood. 

2.  This  stem  divides  into  many  branchlets. 

3 . From  these  branchlets  there  hang  long  fleshy  fringes  like  miniature 
icicles. 

4.  These  fringes  always  hang  downward  when  the  fungus  is  in  natural 
position. 

5 . These  fringes  bear  the  spores. 

LESSON  CLXXXIII 

The  Scarlet  Saucer  ( Sarcocypha  coccinea) 

The  heart  of  the  child,  searching  the  woods  for  hepaticas — woods 
where  snow  banks  still  hold  their  ground  on  north  slopes — is  filled  with 
delight  at  finding  these  exquisite  saucerlike  fungi.  They  are  more  often 
found  on  fallen  rotting  branches  which  are  more  or  less  buried  in  leaves, 
and  there  are  likely  to  be  several  of  different  sizes  on  the  same  stick. 


Flowerless-Plant  Study 


719 


When  they  grow  unhindered  and  while  they  are  young,  they  are  very  per- 
fectly saucer-shaped  and  range  from  the  size  of  a pea  to  an  inch  or  two 
across.  But  the  larger  they  are  the  more  likely  are  they  to  be  distorted, 
either  by  environment  or  by  the  bulging  of  rapid  growth.  The  under  side 
of  the  saucer  is  beautifully  fleshlike  in  color  and  feeling  and  is  attached  at 


Scarlet  saucer . 


the  middle  to  the.  stick.  The  inside  of  the  saucer  is  the  most  exquisite 
scarlet  shading  to  crimson.  This  crimson  lining  bears  the  spores  in  little 
sacs  all  over  its  surface. 

Observations — 1.  Where  did  you  find  the  fungus? 

2.  What  is  the  shape  of  the  saucer?  How  large  is  it?  Is  it  regular 
and  beautiful  or  irregular  and  distorted? 

3.  What  is  the  color  inside? 

4.  What  is  the  color  outside? 

5.  Turn  the  one  you  bring  in  bottom  side  up — that  is,  scarlet  side 
down — on  a piece  of  white  paper,  and  see  whether  you  can  get  a spore 
harvest. 


LESSON  CLXXXIV 

The  Morels 

In  May  or  June  in  open,  damp  places,  as 
orchards  or  the  moist  fence  corners  of  meadows, 
the  morels  may  be  found.  This  mushroom  family 
contains  no  member  that  is  poisonous,  and  the 
members  are  very  unlike  any  other  family  in 
appearance.  They  are  very  pretty  with  their 
creamy  white,  thick,  swollen  stems  and  a cap 
more  or  less  conical,  made  up  of  the  deep-celled 
meshes  of  an  unequal  network.  The  outside 
edges  of  the  network  are  yellowish  or  brownish 
when  the  morel  is  young  and  edible,  but  later 
turn  dark  as  the  spores  develop.  In  some  species 
the  stems  are  comparatively  smooth  and  in  others 
their  surface  is  more  or  less  wrinkled . The  spores 
are  borne  in  the  depressions  of  the  network. 
These  mushrooms  should  not  be  eaten  after  the 
cells  change  from  creamy  white  to  brownish. 

Observations — 1.  Where  did  you  find  the 
morels? 

2.  Describe  the  stem.  Is  it  solid  or  hollow? 
Is  it  smooth  hr  rough  ? 

3 . What  is  the  shape  of  the  cap  ? How  does 
it  look?  What  color  is  the  outer  edge  of  the  net-

meshes? 

4.  Take  one  of  these  fungi,  lay  it  on 
a sheet  of  white  paper,  and  note  the 
color  of  the  spores. 

LESSON  CLXXXV 
The  Stinkhorns 

To  give  a nature-study  lesson  on  the 
stinkhorn  is  quite  out  of  the  question, 
for  the  odor  of  these  strange  growths  is 
so  nauseating  that  even  to  come  near  to 
one  of  them  in  the  garden  is  a disagree- 
able experience.  The  reason  for  men- 
tioning them  at  all  is  because  of  the 
impression  made  by  them  that  most 
mushrooms  are  ill  smelling,  which  is  a 
slander. 

It  is  a pity  that  these  fungi  are  so 
offensive  that  we  do  not  care  to  come 
near  enough  to  them  to  admire  them, 
for  they  are  most  interesting  in  appear- 
ance. The  scientific  name  of  our  com- 
monest genus  when  translated  means 
“the  net  bearers,’’  and  it  is  a most  ap- 
propriate name.  The  stout,  white  stem 
is  composed  of  network  without  and 
within.  The  outer  covering  of  the  stem  seems  to  tear  loose  from  the 
lower  portion  as  the  stem  elongates,  and  is  lifted  so  that  it  hangs  as  a 
veil  around  the  bottom  of  the  bell-shaped  cap,  which  is  always  covered 
with  a pitted  network.  The  mycelium,  or  spawn,  of  the  stinkhorn 
consists  of  strands  which  push  their  way  through  the  ground 
or  through  the  decaying  vegetable  matter  on  which  they  feed. 
On  these  strands  are  produced  the  stinkhorns,  which  at  first 
look  like  eggs;  but  later  the  top  of  the  egg. is  broken,  and  the  strange 
horn-shaped  fungus  pushes  up  through  it.  The  spores  are  borne 
in  the  chambers  of  the  cap,  and  when  ripe  the  substance  of  these 
chambers  dissolves  into  a thick  liquid  in  which  the  spores  float.  The  flies 
are  attracted  by  the  fetid  odor  and  come  to  feast  upon  these  fungi  and  to 
lay  their  eggs  within  them,  and  incidentally  they  carry  the  spores  away 
on  their  brushy  feet,  and  thus  help  to  spread  the  species.

MOLDS 
Teacher's  Story 

It  is  lucky  for  our  peace  of  mind  that  our  eyes  are  not  provided  with 
microscopic  lenses,  for  then  we  should  know  that  the  dust,  which  seems  to 
foregather  upon  our  furniture  from  nowhere,  is  composed  of  all  sorts  of 
germs,  many  of  them  of  the  deadly  kind.  The  spores  of  mold  are  very 


Flowerless -Plant  Study 


721 


minute  objects,  the  spore -cases  being  the  little  white  globes,  not  larger 
than  the  head  of  a small  pin  which  we  see  upon  mold,  yet  each  of  these 
spore-cases  breaks  and  lets  out  into  the  world  thousands  of  spores,  each 
one  ready  and  anxious  to  start  a growth  of  mold  and  perfectly  able  to  do 
it  under  the  right  conditions ; almost  any  substance  which  we  use  for  food, 
if  placed  in  a damp  and  rather  dark  place,  will  prove  a favorable  situation 
for  the  development  of  the  spore  which  swells,  bursts  its  wall  and  sends 
out  a short  thread.  This  gains  nourishment,  grows  longer  and  branches, 
sending  out  many  threads,  some  of  which  go  down  into  the  nutritive 
material  and  are  called  the  mycelium.  While  these  threads,  in  a way,  act 
like  roots,  they  are  not  true  roots.  Presently  the  tip  ends  of  the  threads, 
which  are  spread  out  in  the  air  above  the  bread  or  other  material,  begin  to 
enlarge,  forming  little  globules;  the  substance  (protoplasm)  within  them 
breaks  up  into  little  round  bodies,  and  each  develops  a cell  wall  and  thus 
becomes  a spore.  When  these  are  unripe  they  are  white  but  later,  they 
become  almost  black.  In  the  blue  mold  the  spores  are  borne  in  clusters 
of  chains,  and  resemble  tiny  tassels  instead  of  growing  within  little 
globular  sacs. 

Molds,  mildews,  blights,  rusts  and  smuts  are  all  flowerless  plants  and, 
with  the  mushrooms,  belong  to  the  great  group  of  fungi.  Molds  and 
mildews  will  grow  upon  almost  any  organic  substance,  if  the  right  condi- 
tions of  moisture  are  present,  and  the  temperature  is  not  too  cold. 

Molds  of  several  kinds  may  appear  upon  the  bread  used  in  the  experi- 
ments for  this  lesson.  Those  most  likely  to  appear  are  the  bread  mold — 
consisting  of  long,  white  threads  tipped  with  white,  globular  spore-cases, 
and  the  green  cheese-mold — which  looks  like 
thick  patches  of  blue-green  powder.  Two 
others  may  appear,  one  a smaller  white  mold 
with  smaller  spore-cases,  and  a black  mold. 

However,  the  bread  mold  is  the  one  most 
desirable  for  this  lesson,  because  of  its  com- 
paratively large  size.  When  examined  with  a 
lens,  it  is  a most  exquisite  plant.  The  long 
threads  are  fringed  at  the  sides,  and  they  pass 
over  and  through  each  other,  making  a web 
fit  for  fairies — a web  all  beset  with  the  spore- 
cases,  like  fairy  pearls.  However,  as  the  spores 
ripen,  these  spore-cases  turn  black,  and  after 
a time  so  many  of  them  are  developed  and 
ripened  that  the  whole  mass  of  mold  is  black. 

The  time  required  for  the  development  of  mold 
varies  with  the  temperature.  For  two  or  three 
days  nothing  may  seem  to  be  happening  upon  the  moist  bread;  then  a 
queer,  soft  whiteness  appears  in  patches.  In  a few  hours  or  perhaps 
during  the  night,  these  white  patches  send  up  white  fuzz  which  is  soon 
dotted  with  tiny  pearl-like  spore-cases.  At  first  there  is  no  odor  when  the 
glass  is  lifted  from  the  saucer,  but  after  the  spores  ripen,  the  odor  is  quite 
disagreeable. 

The  special  point  to  teach  the  children  in  this  lesson  is  that  dryness  and 
sunlight  are  unfavorable  to  the  development  of  mold ; and  it  might  be 
well  to  take  one  of  the  luxuriant  growths  of  mold  developed  in  the  dark, 
uncover  it  and  place  it  in  the  sunlight,  and  see  how  soon  it  withers.  The

lesson  should  also  impress  upon  them  that  dust  is  composed,  in  part,  of 
living  germs  waiting  for  a chance  to  grow. 

LESSON  CLXXXVI 

Molds 

Leading  thought — The  spores  of  mold  are  everywhere  and  help  to  make 
what  we  call  dust.  These  spores  will  grow  on  any  substance  which  gives 
them  nourishment,  if  the  temperature  is  warm,  the  air  moist  and  the  sun- 
light is  excluded. 

Method — Take  bread  in  slices  two  inches  square,  and  also  the  juice  of 
apple  sauce  or  other  stewed  fruit.  Have  each  pupil,  or  the  one  who  does 
the  work  for  the  class,  provided  with  tumblers  and  saucers.  Use  four 
pieces  of  bread  cut  in  about  two-inch  squares,  each  placed  on  a saucer; 
moisten  two  and  leave  the  other  two  dry.  With  a feather  or  the  finger 
take  some  dust  from  the  woodwork  of  the  room  or  the  furniture  and  with 
it  lightly  touch  each  piece  of  bread.  Cover  each  with  a tumbler.  Set 
one  of  the  moistened  pieces  in  a warm,  dark  place  and  the  other  in  a dry, 
sunny  place.  Place  a dry  piece  in  similar  situations.  Let  the  pupils 
examine  these  every  two  or  three  days. 

Put  fruit  juice  in  a saucer,  scatter  a little  dust  over  it  and  set  it  in  a 
warm,  dark  place.  Take  some  of  the  same,  do  not  scatter  any  dust  upon 
it,  cover  it  safely  with  a tumbler  and  put  it  in  the  same  place  as  the  other. 
A lens  is  necessary  for  this  lesson,  and  it  is  much  more  interesting  for  the 
pupils  if  they  can  see  the  mold  under  a microscope  with  a three-fourths 
objective. 

Observations — i.  When  does  the  mold  begin  to  appear?  Which 
piece  of  bread  showed  it  first?  Describe  the  first  changes  you  noticed. 
What  is  the  color  of  the  mold  at  first?  Is  there  any  odor  to  it? 

2.  At  what  date  did  the  little  branching  mold-threads  with  round 
dots  appear?  Is  there  an  odor  when  these  appear?  What  are  the  colors 
of  the  dots,  or  spore-cases,  at  first  ? When  do  these  begin  to  change  color  ? 
How  does  the  bread  smell  then  ? What  caused  the  musty  odor  ? 

3.  Did  the  mold  fail  to  appear  on  any  of  the  pieces  of  bread?  If  so, 
where  were  these  placed ? Were  they  moist?  Were  they  exposed  to  the 
sunlight  ? 

4.  Did  more  than  one  kind  of  mold  appear  on  the  bread  ? If  so,  how 
do  you  know  that  they  are  different  kinds  ? Are  there  any  pink  or  yellow 
patcheson  thebread?  If  so,  these  are  made  by  bacteria  and  not  by  mold. 

5.  From  the  results  of  the  experiments,  describe  in  what  temperature 
mold  grows  best.  In  what  conditions  of  dryness  or  moisture?  Does  it 
flourish  in  the  sunlight  or  in  the  dark? 

6.  Where  does  the  mold  come  from?  What  harm  does  it  do?  What 
should  we  do  to  prevent  the  growth  of  mold?  Name  all  of  the  things  on 
which  you  have  seen  mold  or  mildew  growing. 

7.  Examine  the  mold  through  a microscope  or  a lens.  Describe  the 
threads.  Describe  the  little  round  spore-cases.  Look  at  some  of  the 
threads  that  have  grown  down  into  the  fruit  juice.  Are  they  like  the 
ones  which  grow  in  the  air? 

8.  If  you  have  a microscope  cut  a bit  of  the  mold  off,  place  it  in  a 
drop  of  water  on  a glass  slide,  put  on  a cover-glass.  Examine  it  with  a 
three-fourths  objective,  and  describe  the  spores  and  spore-cases.

BACTERIA 
Teacher's  Story. 

The  yellow,  pink  or  purple  spots  developed  upon  the  moist  and  moldy 
bread  are  caused  by  bacteria  and  yeast.  Bacteria  are  one-celled  organ- 
isms now  classed  as  plants ; they  are  the  smallest  known  living  beings,  and 
can  only  be  seen  through  a high  power  microscope. 

Bacteria  grow  almost  everywhere — in  the  soil,  on  all  foods  and  fruits, 
in  the  water  of  ponds,  streams  and  wells,  in  the  mouths  and  stomachs  of 
human  beings,  and  in  fact  in  almost  all  possible  places,  and  occur  in  the 
air.  Most  of  them  are  harmless,  some  of  them  are  useful,  and  some  pro- 
duce disease  in  both  plants  and  animals,  including  man. 

What  bacteria  do  would  require  many  large  volumes  to  enumerate. 
Some  of  them  develop  colors  or  pigments;  some  produce  gases,  often  ill- 
smelling; some  are  phosphorescent;  some  take  nitrogen  from  the  air 
and  fix  it  in  the  soil;  some  produce  putrefaction;  and  some  produce 
disease.  Nearly  all  of  the  “catching  diseases”  are  produced  by  bacteria. 
Diphtheria,  scarlet  fever,  typhoid  fever,  consumption,  influenza,  grippe, 
colds,  cholera,  lockjaw,  leprosy,  blood  poisoning  and  many  other  diseases 
are  the  result  of  bacteria.  On  the  other  hand,  many  of  the  bacteria  are 
beneficial  to  man.  Some  forms  ripen  the  cream  before  churning,  others 
give  flavor  to  butter;  while  some  are  an  absolute  necessity  in  making 
cheese.  The  making  of  cider  into  vinegar  is  the  work  of  bacteria;  some 
clear  the  pollution  from  ponds  and  streams;  some  help  to  decompose  the 
dead  bodies  of  animals,  so  that  they  return  to  the  dust  whence  they  came. 

We  have  in  our  blood  little  cells  whose  business  it  is  to  destroy  the 
harmful  bacteria  which  get  into  the  blood.  These  little  fighting  cells 
move  everywhere  with  our  blood,  and  if  we  keep  healthy  and  vigorous  by 
right  living,  right  food  and  exercise,  these  cells  may  prove  strong  enough 
to  kill  the  disease  germs  before  they  harm  us.  Direct  sunlight  also  kills 
some  of  the  bacteria.  Seven  or  eight  minutes  exposure  to  bright  sunlight 
is  said  to  kill  the  germs  of  tuberculosis.  Exposure  to  the  air  is  also  a help 
in  subduing  disease  germs.  Bichloride  of  mercury,  carbolic  acid,  formal- 
dehyde and  burning  sulphur  also  kill  germs,  and  may  be  applied  to  cloth- 
ing or  to  rooms  in  which  patients  suffering  from  these  germ  diseases  have 
been.  We  can  do  much  to  protect  ourselves  from  harmful  bacteria  by 
being  very  clean  in  our  persons  and  in  our  homes,  by  bathing  frequently 
and  washing  our  hands  with  soap  often.  We  should  eat  only  pure  and 
freshly  cooked  food,  we  should  get  plenty  of  sleep  and  admit  the  sunlight 
to  our  homes ; we  should  spend  all  the  time  possible  in  the  open  air  and  be 
careful  to  drink  pure  water.  If  we  are  not  sure  that  the  water  is  pure,  it 
should  be  boiled  for  twenty  minutes  and  then  cooled  for  drinking. 

In  Experiment  A the  milk  vials  and  the  corks  are  all  boiled,  so  that 
we  may  be  sure  that  no  other  bacteria  than  the  ones  we  chose  are  present,

since  boiling  kills  these  germs.  As  soon  as  the  milk  becomes  discolored 
we  know  that  it  is  full  of  bacteria. 

Experiment  B shows  that  bacteria  can  be  transplanted  to  gelatin, 
which  is  a material  favorable  for  its  growth.  But  the  point  of  this  experi- 
ment is  to  show  the  child  that  a soiled  finger  will  have  upon  it  germs 
which,  by  growing,  cloud  the  gelatin.  They  should  thus  learn  the  value 
of  washing  their  hands  often  or  of  keeping  their  fingers  out  of  their  mouths. 

Experiment  C shows  the  way  the  destructive  bacteria  attack  the 
potato.  The  discolored  spots  show  where  the  decay  begins,  and  the  odor 
is  suggestive  of  decay.  If  a potato  thus  attacked  is  put  in  the  bright  sun- 
light the  bacteria  are  destroyed,  and  this  should  enforce  the  moral  of  the 
value  of  sunshine.

LESSON  CLXXXVII 
Bacteria 

Leading  thought — Bacteria  are  such  small  plants  that  we  cannot  see 
them  without  the  aid  of  a microscope,  but  they  can  be  planted  and 
will  grow.  The  object  of  this  lesson  is  to  enforce  cleanliness. 

Method — Experiment  A — The  bread  used  for  the  mold  experiment  is 
likely  to  develop  spots  of  yellow,  red  or  purple  upon  it,  and  cultures  from 
these  spots  may  be  used  in  this  lesson  as  follows:  Take  some  vials,  boil 

them  and  their  corks,  and  nearly  fill  them  with  milk  that  has  been  boiled. 
Take  the  head  of  a pin  or  hairpin,  sterilize  the  point  by  holding  in  a flame, 
let  it  cool,  touch  one  of  the  yellow  spots  on  the  bread  with  the  point,  being 
careful  to  touch  nothing  else,  and  thrust  the  point  with  the  bacteria  on  it 
into  the  milk ; then  cork  the  vials. 

Experiment  B — Prepare  gelatin  as  for  the  table  but  do  not  sweeten. 
Pour  some  of  this  gelatin  on  clean  plates  or  saucers.  After  it  has  cooled 
let  one  of  the  children  touch  lightly  the  gelatin  in  one  saucer  for  a few 
seconds  with  his  soiled  finger.  Note  the  place.  Ask  him  to  wash  his 
hands  thoroughly  with  soap  and  then  apply  a finger  to  the  surface  of  the 
gelatin  in  the  other  plate.  Cover  both  plates  to  keep  out  the  dust  and 
leave  them  for  two  or  three  days  in  a dark  place.  The  plates  touched  by 
the  soiled  finger  will  show  a clouded  growth  in  the  gelatin ; the  other  plate 
will  show  a few  irregular,  scattered  growths  or  none. 

Experiment  C — Take  a slice  of  boiled  potato,  place  in  a saucer,  leave  it 
uncovered  for  a time  or  blow  dust  upon  it,  label  with  date,  then  cover  with 
a tumbler  to  keep  from  drying  and  place  in  a cool,  somewhat  dark  place. 

The  pupils  should  examine  all  these  cultures  every  day  and  make  the 
following  notes : 

Experiment  A — How  soon  did  you  observe  a change  in  the  color  of  the 
milk?  How  can  you  tell  when  the  milk  is  full  of  the  bacteria?  How  do 
you  know  that  the  bacteria  in  the  milk  was  transplanted  by  the  pin  ? 

Experiment  B — Can  you  see  that  the  gelatin  is  becoming  clouded 
where  the  soiled  finger  touched  it  ? This  is  a growth  of  the  bacteria  which 
were  on  the  soiled  finger. 

Experiment  C — What  change  has  taken  place  in  the  appearance  of  the 
slice  of  potato  ? Are  there  any  spots  gro wing  upon  it  ? What  is  the  odor  ? 


Flowerless-Plant  Study 


725 

What  makes  the  spots?  Describe  the  shape  of  the  spots.  The  color. 
Are  any  of  them  pimple-shaped  ? Make  a drawing  of  the  slice  of  potato 
showing  the  bacteria  spots.  What  are  the  bacteria  doing  to  the  potato? 
Take  a part  of  the  slice  of  potato  with  the  bacteria  spots  upon  it,  and  put 
it  in  the  sunshine.  What  happens?  Compare  this  with  the  part  kept  in 
the  dark. 

After  this  lesson  the  children  should  be  asked  the  following  questions. 

1.  Why  should  the  hands  always  be  washed  before  eating? 

2.  Why  should  the  finger  nails  be  kept  clean? 

3.  Why  should  we  never  bite  the  finger  nails  nor  put  the  fingers  in 
the  mouth  ? 

4.  Why  should  we  never  put  coins  in  the  mouth? 

5.  Why  should  wounds  be  carefully  cleansed  and  dressed  at  once? 

6.  Why  should  clothing,  furniture  and  the  house  be  kept  free  from 
dust? 

7.  Why  should  sweeping  be  done  as  far  as  possible  without  raising 
dust? 

8.  Why  are  hardwood  floors  more  healthful  than  carpets? 

9.  Why  is  a damp  cloth  better  than  a feather  duster  for  removing 
dust? 

10.  Why  should  the  prohibition  against  spitting  in  public  places  be 
strictly  enforced  ? 

11.  Why  should  the  dishes,  clothes  and  other  articles  used  bysick 
persons  be  kept  distinctly  separate  from  those  used  by  well  members  of 
the  family  ? 

1 2 . Why  should  food  not  be  exposed  for  sale  on  the  street  ? 

1 3 . Why,  during  an  epidemic,  should  water  be  boiled  before  drinking  ? 


“ This  habit  of  looking  first  at  what  we  call  the  beauty  of  objects  is  closely  associated 
•with  the  old  conceit  that  everything  is  made  to  please  man:  man  is  only  demanding  his 

own.  It  is  true  that  everything  is  man's  because  he  may  use  it  or  enjoy  it,  but  not 
because  it  was  designed  and 'made' for  'him'  in  the  beginning.  This  notion  that  all 
things  were  made  for  man's  special  pleasure  is  colossal  self-assurance.  It  has  none  of 
the  humility  of  the  psalmist,  who  exclaimed,  ' What  is  man,  that  thou  art  mindful  of 
him ? 

" 'What  were  these  things  made  for , then!'  asked  my  friend.  Just  for  themselves! 
Each  thing  lives  for  itself  and  its  kind,  and  to  live  is  worth  the  effort  of  living  for  man 
or  bug.  But  there  are  more  homely  reasons  for  believing  that  things  were  not  made  for 
man  alone.  There  was  logic  in  the  farmer's  retort  to  the  good  man  who  told  him  that 
roses  were  made  to  make  man  happy.  'No,  they  wa’n't',  said  the  farmer,  ‘or  they 
wouldn't  a had  pricker sJ  A teacher  asked  me  what  snakes  are  ‘good  for.'  Of  course 
there  is  but  one  answer:  they  are  good  to  be  snakes."

TREE  STUDY 
Teacher's  Story 

“ I wonder  if  they  like  it — being  trees? 

I suppose  they  do. 

It  must  feel  so  good  to  have  the  ground  so  flat, 

A nd  feel  yourself  stand  straight  up  like  that. 

So  stiff  in  the  middle;  and  then  branch  at  ease, 

Big  boughs  that  arch,  small  ones  that  bend  and  blow, 

And  all  those  fringy  leaves  that  flutter  so., 

You'd  think  they'd  break  off  at  the  lower  end 
When  the  wind  fills  them,  and  their  great  heads  bend. 

But  when  you  think  of  all  the  roots  they  drop, 

As  much  at  bottom  as  there  is  on  top, 

A double  tree,  widespread  in  earth  and  air, 

Like  a reflection  in  the  water  there." 

— “Tree  Feelings”  by  Charlotte  Perkins  Stetson 

YTURAL  is  our  love  for  trees!  A tree  is  a 
living  being,  with  a life  comparable  to  our  own. 
In  one  way  it  differs  from  us  greatly:  it  is  sta- 
tionary, and  it  has  roots  and  trunk  instead  of 
legs  and  body ; it  is  obliged  to  wait  to  have 
what  it  needs  come  to  it,  instead  of  being  able 
to  search  the  wide  world  over  to  satisfy  its 
wants. 

THE  PARTS  OF  THE  TREE 

The  head,  or  crown,  is  composed  of  the 
branches  as  a whole,  which  in  turn  are  composed 
of  the  larger  and  smaller  branches  and  twigs. 
The  spray  is  the  term  given  to  the  outer  twigs,  the  finest  divisions  of  the 
trunk,  which  bear  the  leaves  and  fruit.  The  branches  are  divisions  of  the 
bole,  or  trunk,  which  is  the  body,  or  stem,  of  the  tree.  The  bole,  at  the  base, 


Tree  Study 


727 

divides  into  roots,  and  the  roots  into  rootlets,  which  are  covered  with  root- 
hairs.  It  is  important  to  understand  what  each  of  the  parts  of  a tree’s 
anatomy  does  to  help  carry  on  theflife  of  the  tree. 


The  roots,  which  extend  out  in  every  direction  beneath  the  surface  of 
the  ground,  have  two  quite  different  offices  to  perform : First,  they  absorb 
the  water  which  contains  the  tree  food  dissolved  from  the  soil;  second,  they 
hold  the  tree  in  place  against  the  onslaught  of  the  winds.  If  we  could  see  a 
0 tree  standing  on  its  head  with  its  roots  spread  in  the  air  in  the  same  manner 
as  they  are  in  the  ground,  we  could  then  better  understand  that  there  is  as 
much  of  the  tree  hidden  below  ground  as  there  is  in  sight  above  ground, 
although  of  quite  different  shape,  being  flatter  and  in  a more  dense  mass. 
The  roots  seem  to  know  in  which  direction  to  grow  to  reach  water;  thus,  the 
larger  number  of  the  roots  of  a tree  are  often  found  to  extend  out  toward  a 
stream  flowing  perhaps  some  distance  from  the  tree ; when  they  find  plenty 
of  food  and  water  the  rootlets  interlace  forming  a solid  mat.  On  the 
Cornell  Campus  are  certain  elms  which,  every  six  or  seven  years,  completely 
fill  and  clog  the  nearby  sewers ; these  trees  send  most  of  their  roots  in  the 
direction  of  the  sewer  pipe.  The  fine  rootlets  upon  the  tree-roots  are 
covered  with  root-hairs,  which  really  form  the  mouths  by  which  the  liquid 
food  is  taken  into  the  tree. 


Handbook  of  Nature-Study 


728 

To  understand  how  firm  a base  the  roots  form  to  hold  up  the  tall  trunk, 
we  need  to  see  an  uprooted  tree.  The  great  roots  seem  to  be  molded  to  take 

firm  grasp  upon 
the  soil.  It  is 
interesting  to 
study  some  of 
the  “stump 
fences”  which 
were  made  by 
our  forefathers, 
who  uprooted 
the  white  pines 
when  the  land 
was  cleared  of 
the  primeval  for- 
est, and  made 
fences  of  their 
widespreading 
but  rather  shal- 
low extending 
roots.  Many  of 
these  fences 
stand  to-day 

with  branching,  out-reaching  roots,  white  and  weather-worn,  but  still 
staunch  and  massive  as  if  in  memory  of  their  strong  grasp  upon  the  soil 
of  the  wilderness. 

The  trunk,  or  bole,  or  stem  of  the  tree  has  also  two  chief  offices:  It 

holds  the  branches  aloft,  rising  to  a sufficient  height  in  the  forest  so  that  its 
head  shall  push  through  the  leaf  canopy  and  expose  the  leaves  to  the  sun- 
light. It  also  is  a channel  by  which  the  water  containing  the  food  surges 
from  root  to  leaf  and  back  again  through  each  growing  part.  The  branches 
are  divisions  of  the  trunk,  and  have  the  same  work  to  do. 

In  cross-section,  the  tree  trunk  shows  on  the  outside  the  layer  of  protec- 
tive bark ; next  to  this  comes  the  cambium  layer,  which  is  the  vital  part  of 
the  trunk;  it  builds  on  its  outside  a layer  of  bark,  and  on  its  inside  a layer 
of  wood  around  the  trunk.  Just  within  the  cambium  layer  is  a lighter 
colored  portion  of  the  trunk,  which  is  called  the  sap-wood  because  it  is  filled 
with  sap  which  moves  up  and  down  its  cells  in  a mysterious  manner;  the 
sap-wood  consists  of  the  more  recent  annual  rings  of  growth.  Within  the 
sap-wood  are  concentric  rings  to  the  very  center  or  pith ; this  portion  is 
usually  darker  in  color  and  is  called  the  heartwood;  it  no  longer  has 
anything  to  do  with  the  life  of  the  tree,  but  simply  gives  to  it  strength  and 
staunchness.  The  larger  branches,  if  cut  across,  show  the  same  structure 
as  the  trunk, — the  bark  on  the  outside,  the  cambium  layer  next,  and 
within  this  the  rings  of  annual  growth.  Even  the  smaller  branches  and 
twigs  show  similar  structure,  but  they  are  young  and  have  not  attained 
many  annual  rings. 

The  leaves  are  borne  on  the  outermost  parts  of  the  tree.  A leaf 
cannot  grow,  and  if  it  could  would  be  of  no  use,  unless  it-  can  be  reached 
by  the  sunlight.  Therefore  the  trunk  lifts  the  branches  aloft,  and 
the  branches  hold  the  twigs  far  out,  and  the  twigs  divide  into  the 
fine  spray,  so  as  to  spread  the  leaves  and  hold  them  out  into  the  sunshine.

In  structure,  the  leaf  is  made  up  of  the  stem,  or  petiole,  and  the  blade,  or 
widened  portion  of  the  leaf,  Which  is  sustained  usually  with  a framework  of 
many  ribs  or  veins.  The  petioles  and  the  veins  are  sap  channels  like  the 
branches  and  twigs. 

WOOD-GRAIN 

This  is  the  way  that  the  sap-river  ran 
From  the  root  to  the  top  of  the  tree 
Silent  and  dark, 

Under  the  bark, 

Working  a wonderful  plan 
That  the  leaves  never  know, 

And  the  branches  that  grow 
On  the  brink  of  the  tide  never  see. 

— John  B.  Tabb. 

THE  WAY  A TREE  GROWS 

HE  places  of  growth  on  a tree  may  be  found  at  the  tips  of  the 
twigs  and  the  tips  of  the  rootlets ; each  year  through  this 
growth  the  tree  pushes  up  higher,  down  deeper  and  out 
farther  at  the  sides.  But  in  addition  to  all  of  these  grow- 
ing tips,  there  is  a layer  of  growth  over  the  entire  tree — 
over  every  root,  over  the  trunk,  over  the  limbs  and  over 
each  least  twig,  just  as  if  a thick  coat  of  paint  had  been 
put  over  the  complete  tree.  It  is  a coat  of  growth  instead,  and 
these  coats  of  growth  make  the  concentric  rings  which  we  see  when 
the  trunks  or  branches  are  cut  across.  Such  growth  as  this  cannot 
be  made  without  food;  but  the  tree  can  take  only  liquid  food  from  the 
soil;  the  root-hairs  take  up  the  water  in  which  the  “fertilizer”  is 
dissolved,  and  it  is  carried  up  through  the  larger  roots,  up  through 
the  sap-wood  of  the  trunk,  out  through  the  branches  to  the  leaves, 
where  in  the  leaf-factories  the  water  and  free  oxygen  is  given  off  to  the 
air,  and  the  nourishing  elements  retained  and  mixed  with  certain 
chemical  elements  of  the  air,  thus  becoming  tree  food.  The  leaf  is  a factory ; 
the  green  pulp  in  the  leaf  cells  is  part  of  the  machinery ; the  machinery  is 
set  in  motion  by  sunshine  power ; the  raw  materials  are  taken  from  the  air 
and  from  the  sap  containing  food  from  the  soil;  the  finished  product  is 
largely  starch.  Thus,  it  is  well,  when  we  begin  the  study  of  the  tree,  to 
notice  that  the  leaves  are  so  arranged  as  to  gain  all  the  sunlight  possible,  for 
without  sunlight  the  starch  factories  would  be  obliged  to  “shut  down.”  It 
has  been  estimated  that  on  a mature  maple  of  vigorous  growth  there  is 
exposed  to  the  sun  nearly  a half  acre  of  leaf  surface.  Our  tree  appears  to  us 
in  a new  phase  when  we  think  of  it  as  a starch  factory  covering  half  an  acre. 

Starch  is  plant  food  in  a convenient  form  for  storage,  and  it  is  stored  in 
sap-wood  of  the  limbs,  the  branches  and  trunk,  to  be  used  for  the  growth  of 
the  next  year’s  leaves.  But  starch  cannot  be  assimilated  by  plants  in  this 
form,  it  must  be  changed  to  sugar  before  it  may  be  used  to  build  up  the 
plant  tissues.  So  the  leaves  are  obliged  to  perform  the  office  of  stomach  and 
digest  the  food  they  have  made  for  the  tree’s  use.  In  the  mysterious 
laboratory  of  the  leaf-cells,  the  starch  is  changed  to  sugar;  and  nitrogen, 
sulphur,  phosphorus  and  other  substances  are  taken  from  the  sap  and  starch 
added  to  them,  and  thus  are  made  the  proteids  which  form  another  part  of 


Handbook  of  Nature-Study 


730 

the  tree’s  diet.  It  is  interesting  to  note  that  while  the  starch  factories  can 
operate  only  in  the  sunlight,  the  leaves  can  digest  the  food  and  it  can  be 
transported  and  used  in  the  growing  tissues  in  the  dark.  The  leaves  are 
also  an  aid  to  the  tree  in  breathing,  but  they  are  not  especially  the  lungs  of 
the  tree.  The  tree  breathes  in  certain  respects  aswe  do ; it  takes  in  oxygen 

and  gives  off  carbondi- 
oxid;  but  the  air  con- 
taining the  oxygen  is 
taken  in  through  the 
numerous  pores  in  the 
leaves  called  stomata,  and 
also  through  lenticels  in 
the  bark;  so  the  tree 
really  breathes  all  over 
its  active  surface. 

The  tree  is  a rapid 
worker  and  achieves  most 
of  its  growth  and  does 
most  of  its  work  by  mid- 
summer. The  autumn 
leaf  which  is  so  beautiful 
has  completed  its  work. 
The  green  starch-machin- 
ery or  chlorophyl,  the 
living  protoplasm  in  the 
leaf  cells,  has  been  with- 
drawn and  is  safely  se- 
cluded in  the  woody  part 
of  the  tree.  The  autumn 
leaf  which  glows  gold  or 
red,  has  in  it  only  the 
material  which  the  tree 
A stump  showing  rings  of  growth.  can  110  longer  use.  It  is 

a mistake  to  believe  that 
the  frost  causes  the  brilliant  colors  of  autumn  foliage;  they  are  caused 
by  the  natural  old  age  and  death  of  the  leaves — and  where  is  there  to 
be  found  old  age  and  death  more  beautiful?  When  the  leaf  assumes  its 
bright  colors,  it  is  making  ready  to  depart  from  the  tree;  a thin,  corky  layer 
is  being  developed  between  its  petiole  and  the  twig,  and  when  this  is  per- 
fected, the  leaf  drops  from  its  own  weight  or  the  touch  of  the  slightest  breeze. 

A tree,  growing  in  open  ground,  records  in  its  shape,  the  direction  of  the 
prevailing  winds.  It  grows  more  luxuriantly  on  the  leeward  side.  It 
touches  the  heart  of  the  one  who  loves  trees  to  note  their  sturdy  endurance 
of  the  onslaughts  of  this,  their  most  ancient  enemy.

HOW  TO  BEGIN  TREE  STUDY 


Teacher's  Story 


'URING  autumn  the  attention  of  the  children  should  be 
attracted  to  the  leaves  by  their  gorgeous  colors.  It  is 
well  to  use  this  interest  to  cultivate  their  knowledge  of 
the  forms  of  leaves  of  trees;  but  the  teaching  of  the  tree 
species  to  the  young  child  should  be  done  quite  incidentally 
and  guardedly.  If  the  teacher  says  to  the  child  bringing 
a leaf,  “This  is  a white  oak  leaf,”  the  child  will  soon  quite 
unconsciously  learn  that  leaf  by  name.  Thus,  tree  study 
may  be  begun  in  the  kindergarten  or  the  primary  grades. 

i .  Let  the  pupils  use  their  leaves  as  a color  lesson  by  classifying  them 
according  to  color,  and  thus  train  the  eye  to  discriminate  tints  and  color 
values. 


2.  Let  them  classify  the  leaves  according  to  form,  selecting  those  which 
resemble  each  other. 

3.  Let  each  child  select  a leaf  of  his  own  choosing  and  draw  it.  This 
may  be  done  by  placing  the  leaf  flat  on  paper  and  outlining  it  with  pencil 
or  with  colored  crayon. 

4.  Let  the  pupils  select  paper  of  a color  similar  to  the  chosen  leaf  and 
cut  a paper  leaf  like  it. 

5 . Let  each  pupil  select  four  leaves  which  are  similar  and  arrange  them 
on  a card  in  a symmetrical  design.  This  may  be  done  while  the  leaves 
are  fresh,  and  the  card  with  leaves  may  be  pressed  and  thus  preserved. 

In  the  fourth  grade,  begin  with  the  study  of  a tree  which  grows  near  the 
schoolhouse.  In  selecting  this  tree  and  in  speaking  of  it,  impress  upon  the 
children  that  it  is  a living  being,  with  a life  and  with  needs  of  its  own.  I 
believe  so  much  in  making  this  tree  seem  an  individual,  that  I would  if 
necessary  name  it  Pocahontas  or  Martha  Washington.  First,  try  to  ascer- 
tain the  age  of  the  tree.  Tell  an  interesting  story  of  who  planted  it  and 
who  were  children  and  attended  school  in  the  schoolhouse  when  the  tree 
was  planted.  To  begin  the  pupils’  work,  let  each  have  a little  note-book  in 
which  shall  be  written,  sketched  or  described  all  that  happens  to  this  parti- 
cular tree  for  a year.  The  following  words  with  their  meaning  should  be 
given  in  the  reading  and  spelling  lessons:  Head , bole,  trunk,  branches, 
twigs,  spray,  roots,  bark,  leaf,  petiole,  foliage,  sap.

LESSON  CLXXXVIII 
Tree  Study 

Autumn  Work — i.  What  is  the  color  of  the  tree  in  its  autumn  foliage? 
Sketch  it  in  water  colors  or  crayons,  showing  the  shape  of  the  head,  the  rela- 
tive proportions  of  head  and  trunk. 

2.  Describe  what  you  can  see  of  the  tree’s  roots.  How  far  do  you  sup- 
pose the  roots  reach  down  ? How  far  out  at  the  sides  ? In  how  many  ways 
are  the  roots  useful  to  the  tree  ? Do  you  suppose,  if  the  tree  were  turned 
bottomside  up,  that  it  would  show  as  many  roots  as  it  now  shows  branches? 

3 . How  high  on  the  trunk  from  the  ground  do  the  lower  branches  come 
off?  How  large  around  is  the  trunk  three  feet  from  the  ground?  If  you 
know  how  large  around  it  is,  how  can  you  get  the  distance  through?  What 
is  the  color  of  the  bark ? Is  the  bark  smooth  or  rough?  Are  the  ridges  fine 
or  coarse  ? Are  the  furrows  between  the  ridges  deep  or  shallow  ? Of  what 
use  is  the  bark  to  the  tree? 

4.  Describe  the  leaf  from  your  tree,  paying  special  attention  to  its 
shape,  its  edges,  its  color  above  and  below,  its  veins  or  ribs,  and  the  relative 
length  and  thickness  of  its  petiole.  Are  the  leaves  set  opposite  or  alternate 
upon  the  twigs?  As  the  leaves  begin  to  fall,  can  you  find  two  which  are 
exactly  the  same  in  size  and  shape  ? Draw  in  your  note-book  the  two  leaves 
which  differ  most  from  each  other  of  any  that  grew  on  your  tree.  At  what 
date  do  the  leaves  begin  to  fall  from  your  tree?  At  what  date  are  they  all 
off  the  tree?

5.  Do  you  find  any  fruit  or  seed  upon  your  tree?  If  so  describe  and 
sketch  it,  and  tell  how  you  think  it  is  scattered  and  planted. 

Winter  Study  of  the  Tree — 1.  Make  a sketch  of  the  tree  in  your  note- 
book, showing  its  shape  as  it  stands  bare.  Does  the  trunk  divide  into 
branches,  or  does  it  extend  through  the  center  of  the  tree  and  the  branches 
come  off  from  its  sides?  Of  what  use  are  the  branches  to  a tree?  Is  the 
spray,  or  the  twigs  at  the  end  of  the  branches,  coarse  or  fine?  Does  it  lift 
up  or  droop  ? Is  the  bark  on  the  branches  like  that  on  the  trunk  ? Is  the 
color  of  the  spray  the  same  as  of  the  large  branches  ? Why  does  the  tree 
drop  its  leaves  in  winter  ? Does  the  tree  grow  during  the  winter  ? Do  you 
think  that  it  sleeps  during  the  winter? 

2.  Study  the  cut  end  of  a log  or  stump  and  also  study  a slab.  Which 
is  the  heart-wood  and  which  is  the  sap-wood?  Can  you  see  the  rings  of 
growth?  Can  you  count  these  rings  and  tell  how  old  was  the  tree  from 
which  this  log  came?  Describe  if  you  can,  how  a tree  trunk  grows  larger 
each  year.  What  is  it  makes  the  grain  in  the  wood  which  we  use  for  furni- 
ture ? If  we  girdle  a tree  why  does.it  die  ? If  we  place  a nail  in  a tree  three 
feet  from  the  ground  this  winter,  will  it  be  any  higher  from  the  ground  ten 
years  from  now  ? How  does  the  tree  grow  tall  ? 

3.  Take  a twig  of  a tree  in  February  and  look  carefully  at  the  buds. 
What  is  their  color?  Are  they  shiny,  rough,  sticky  or  downy?  Are  they 
arranged  on  the  twigs  opposite  or  alternate  ? Can  you  see  the  scar  below 
the  buds  where  the  last  year’s  leaf  was  borne  ? Place  the  twig  in  water  and 
put  in  a light,  warm  place,  and  see  what  happens  to  the  buds.  As  the 
leaves  push  out,  what  happens  to  the  scales  which  protected  the  buds? 

4.  What  birds  do  you  find  visiting  your  tree  during  winter  ? Tie  some 
strips  of  beef  fat  upon  its  branches,  and  note  all  of  the  kinds  of  birds  which 
come  to  feast  upon  it. 


Trees  in  winter.

Spring  Work— i.  At  what  date  do  the  young  leaves  appear  upon  your 
tree  ? What  color  are  they  ? Look  carefully  to  see  how  each  leaf  was  folded 
in  the  bud.  Were  all  the  leaves  folded  in  the  same  way?  Are  the  young 
leaves  thin,  downy  and  tender?  Do  they  stand  out  straight  as  did  the  old 
leaves  last  autumn,  or  do  they  droop?  Why?  Will  they  change  position 
and  stand  out  as  they  grow  stronger  ? Why  do  the  leaves  stand  out  from 
the  twigs  in  order  to  get  sunshine  ? What  would  happen  to  a tree  if  it  lost 
all  its  leaves  in  spring  and  summer?  Tell  all  of  the  things  you  know  which 
the  leaves  do  for  the  tree? 

2.  Are  there  any  blossoms  on  your  tree  in  the  spring?  If  so,  how  do 
they  look?'  Are  the  blossoms  which  bear  the  fruit  on  different  trees  from 
those  that  bear  the  pollen,  or  are  these  flowers  placed  separately  on  the  same 
tree  ? Or  does  the  same  flower  which  produces  the  pollen  also  produce  the 
seed?.  Do  the  insects  carry  the  pollen  from  flower  to  flower,  or  does  the 
wind  do  this  for  your  tree  ? What  sort  of  seeds  are  formed  by  these  flowers  ? 
How  are  the  seeds  scattered  and  planted? 

3.  At  what  date  does  your  tree  stand  in  full  leaf?  What  color  is  it 
now  ? What  birds  do  you  find  visiting  it  ? What  insects  ? What  animals 
seek  its  shade?  Do  the  squirrels  live  in  it? 

4.  Measure  the  height  of  your  tree  as  follows : Choose  a bright,  sunny 

morning  for  this. Take  a stick  3F2  feet  long  and  thrust  it  in  the  ground  so 
that  three  feet  will  project  above  the  soil.  Immediately  measure  the  length 
of  its  shadow  and  of  the  shadow  which  your  tree  makes  from  its  base  to  the 
shadow  of  its  topmost  twigs.  Supposing  that  the  shadow  from  the  stick  is 
4 feet  long  and  the  shadow  from  your  tree  is  80  feet  long,  then  your  example 
will  be : 4 ft.  13  ft. : : 80  ft. :?  Which  will  make  the  tree  60  feet  high. 

To  measure  the  circumference  of  the  tree,  take  the  trunk  three  feet  from 
the  ground  and  measure  it  exactly  with  a tape  measure.  To  find  the  thick- 
ness of  the  trunk,  divide  the  circumference  just  found  by  3.15.

LESSON  CLXXXIX 
How  to  Make  Leaf  Prints 

A very  practical  help  in  interesting  children  in  trees,  is  to  encourage  them 
to  make  portfolios  of  leaf -prints  of  all  the  trees  of  the  region.  Although  the 
process  is  mechanical,  yet  the  fact  that  every  print  must  be  correctly  labeled 
makes  for  useful  knowledge.  One  of  my  treasured  possessions  is  such  a 
portfolio  made  by  the  lads  of  St.  Andrews  School  of  Richmond,  Va.,  who 
were  guided  and  inspired  in  this  work  by  their  teacher,  Professor  W.  W. 
Gillette.  The  impressions  were  made  in  green  ink  and  the  results  are  as 
beautiful  as  works  of  art.  Professor  Gillette  gave  me  my  first  lesson  in 
making  leaf  prints. 

Material — 1.  A smooth  slate,  or  better,  a thick  plate  of  glass,  about 
12x15  inches. 

2.  A tube  of  printer’s  ink,  either  green  or  black,  and  costing  50  cents; 
one  tube  contains  a sufficient  supply  of  ink  for  making  several  hundred 
prints.  Or  a small  quantity  of  printer’s  ink  may  be  purchased  at  any 
printing  office.

3.  Two  six-inch  rubber  rollers,  such  as  photographers  use  in  mounting 
prints,  which  cost  1 5 cents  each.  A letter-press  may  be  used  instead  of  one 
roller. 

4.  A small  bottle  of  kerosene  to  dilute  the  ink,  and  a bottle  of  benzine 
for  cleaning  the  outfit  after  using,  care  being  taken  to  store  them  safe  from 
fire. 

5.  Sheets  of  paper  8^2  x 11  inches.  The  paper  should  be  of  good 
quality,  with  smooth  surface  in  order  that  it  may  take  and  hold  a clear  out-

line.  The  ordinary  paper  used  in  printers’  offices  for  printing  newspapers 
works  fairly  well.  I have  used  with  success  the  paper  from  blank  note- 
books which  cost  five  cents  a piece. 

To  make  a print,  place  a few  drops  of  ink  upon  the  glass  or  slate,  and 
spread  it  about  with  the  roller  until  there  is  a thin  coat  of  ink  upon  the  roller 
and  a smooth  patch  in  the  center  of  the  glass  or  slate.  It  should  never  be  so 
liquid  as  to  “run,”  for  then  the  outlines  will  be  blurred.  Ink  the  leaf  by 
placing  it  on  the  inky  surface  of  the  glass  and  passing  the  inked  roller  over 
it  once  or  twice  until  the  veins  show  that  they  are  smoothly  filled.  Now 
place  the  inked  leaf  between  two  sheets  of  paper  and  roll  once  with  the  clean

roller,  bearing  on  with  all  the  strength  possible;  a second  passage  of  the 
roller  blurs  the  print.  Two  prints  are  made  at  each  rolling,  one  of  the 
upper,  and  one  of  the  under  side  of  the  leaf.  Dry  and  wrinkled  leaves  may 
be  made  pliant  by  soaking  in  water,  drying  between  blotters  before  they  are 
inked. 

Prints  may  also  be  made  a number  at  a time  by  pressing  them  under 
weights,  being  careful  to  put  the  sheets  of  paper  with  the  leaves  between 
the  pages  of  old  magazines  or  folded  newspapers,  in  order  that  the  impres- 
sion of  one  set  of  leaves  may  not  mar  the  others.  If  a letter-press  is  avail- 
able for  this  purpose,  it  does  the  work  quickly  and  well.

Strong  as  the  sea  and  silent  as  the  grave, 

It  flows  and  ebbs  unseen,

With  mists  of  deepening  green.

THE  MAPLES 
Teacher's  Story 

E sugar  maple,  combining  beauty  with  many  kinds  of 
utility,  is  dear  to  the  American  heart.  Its  habits  of 
growth  are  very  accommodating;  when  planted  where 
it  has  plenty  of  room,  it  shows  a short  trunk  and 
oval  head,  which,  like  a dark  green  period,  prettily 
punctuates  the  summer  landscape;^  but  when  it 
occurs  in  the  forest,  its  noble  bole,  a pillar  of  granite 
gray,  rises  to  uphold  the  arches  of  the  forest  canopy; 
and  it  attains  there  the  height  of  ioo  feet.  It  grows 
rapidly  and  is  a favorite  shade  tree,  twenty  years 
being  long  enough  to  make  it  thus  useful.  The 
foliage  is  deep  green  in  the  summer,  the  leaf  being  a glossy,  dark  green  above 
and  paler  beneath.  It  has  five  main  lobes,  the  two  nearest  the  stem  being 
smaller;  the  curved  edges  between  the  lobes  are  marked  with  a few, 
smoothly  cut,  large  teeth;  the  main  veins  extend  directly  from  the  petiole 
to  the  sharp  tips  of  the  lobes ; the  petiole  is  long,  slender,  and  occasionally 
red.  The  leaves  are  placed  opposite.  The  shade  made  by  the  foliage  of  the 
maple  is  so  dense  that  it  shades  down  the  plants  beneath  it,  even  grass  grow- 
ing but  sparsely  there.  If  a shade  tree  stands  in  an  exposed  position,  it 
grows  luxuriously  to  the  leeward  of  the  prevailing  winds,  and  thus  makes  a 
one-sided  record  of  their  general  direction. 

It  is  its  autumn  transfiguration  which  has  made  people  observant  of  the 
maple’s  beauty;  yellow,  orange,  crimson  and  scarlet  foliage  make  these 
trees  gorgeous  when  October  comes.  Nor  do  the  trees  get  their  color  uni- 
formly; even  in  September,  the  maple  will  show  a scarlet  branch  in  the 
midst  of  its  green  foliage.  I believe  this  is  a hectic  flush  and  a premonition 
of  death  to  the  branch  which,  less  vigorous  than  its  neighbors,  is  being 
pruned  out  by  Nature’s  slow  but  sure  method.  After  the  vivid  color  is  on 
the  maple,  it  begins  to  shed  its  leaves.  This  is  by  no  means  the  sad  act 
which  the  poets  would  have  us  believe;  the  brilliant  colors  are  an  evidence 


Tree  Study 


737 


that  the  trees  have  withdrawn  from  the  leaves  the  green  life-substance,  the 
protoplasm-machinery  for  making  the  starch,  and  have  stored  it  snugly  in 
trunk  and  branch  for  winter  keeping.  Thus,  only  the  mineral  substances 
are  left  in  the  leaf,  and  they  give  the  vivid  hues.  It  is  a mistake  to  think 
that  frost  causes  this  brilliance;  it  is  caused  by  the  natural,  beautiful,  old 
age  of  the  leaf.  When  the  leaves  finally  fall,  they  form  a mulch-carpet  for 
the  tree  that  bore  them,  and  add  their  substance  to  the  humus  from  which 
the  tree  draws  new  powers  for  growth. 

After  every  leaf  has  fallen,  the  maple  shows  why  its  shade  is  dense.  It 
has  many  branches  set  close  and  at  sharp  angles  to  the  trunk,  dividing  into 
fine,  erect  spray,  giving  the 
tree  a resemblance  to  a giant 
whisk-broom.  Its  dark,  deep- 
furrowed  bark  smoothes  out 
and  becomes  light  gray  on  the 
larger  limbs,  while  the  spray 
is  purplish,  a color  given  it  by 
the  winter  buds.  These  buds 
are  sharp-pointed  and  long. 

In  February,  their  covering  of 
scales  shows  premonitions  of 
spring  by  enlarging,  and  as  if 
due  to  the  soft  influence,  they 
become  downy,  and  take  on  a 
sunshine  color  before  they  are 
pushed  off  by  the  leaves.  The 
leaves  and  the  blossoms  appear 
together.  The  leaves  are  at 

first,  yellowish,  downy  and  Sugar  maple  leaver. 

drooping,  thus  shunning  the 

too  hot  sun  and  the  violent  pelting  rains  and  fierce  spring  winds.  The 
flowers  appear  in  tassellike  clusters,  each  downy  drooping  thread  of  the  tassel 
bearing  at  its  tip  a five-lobed  calyx,  which  may  hold  seven  or  eight  long, 


738 


Handbook  of  Nature-Study 


drooping  stamens  or  a pistil  with  long,  double  stigmas.  The  flowers  are 
greenish  yellow,  and  those  that  bear  pollen  and  those  that  bear  the  seeds 
may  be  borne  on  separate  trees  or  on  the  same  tree,  but  they  are  always  in 
different  clusters.  If  on  the  same  tree,  the  seed-bearing  tassels  are  at  the 
tips  of  the  twigs,  and  those  bearing  pollen  are  along  the  sides. 

The  ovary  is  two-celled, 
but  there  is  usually  only 
one  seed  developed  in  the 
pair  which  forms  a “key;” 
to  observe  this,  however, 
we  have  to  dissect  the 
seeds;  they  have  the  ap- 
pearance of  two  seeds 
joined  together,  each  pro- 
vided with  a thin,  closely 
veined  wing  and  the  two 
attached  to  the  tree  by  a 
single  long,  drooping  stem. 
This  twin-winged  form  is 
well  fitted  to  be  whirled 
off  by  the  autumn  winds, 
for  the  seeds  ripen  in  Sep- 
tember. I have  seen  seed- 
lings growing  thickly  for 
rods  to  the  leeward  of  their 
parent  tree,  which  stood 
in  an  open  field.  The 
maples  bear  blossoms  and 
seeds  every  year.  There 
are  six  species  of  native 
maples  which  are  readily 
distinguishable.  The  sil- 
ver and  the  red  maples  and 
the  box  elder  are  rather 
large  trees;  the  mountain 
and  the  striped  (or  goose- 
foot)  maples  are  scarcely

mostly  grow  in  woods 
along  streams.  The  Norway  and  the  sycamore  maples  have  been  intro- 
duced from  Europe  for  ornamental  planting.  The  cut-leaf  silver  maple 
comes  from  Japan. 

The  maple  wood  is  hard,  heavy,  strong,  tough  and  fine-grained;  it  is 
cream-color,  the  heart-wood  showing  shades  of  brown ; it  takes  a fine  polish 
and  is  used  as  a finishing  timber  for  houses  and  furniture.  It  is  used  in  con- 
struction of  ships,  cars,  piano  action  and  tool  handles;  its  fine-grained 
quality  makes  it  good  for  wood-carving;  it  is  an  excellent  fuel  and  has  many 
other  uses. 


MAPLE-SUGAR  MAKING 

Although  we  have  tapped  the  trees  in  America  for  many  hundred  years, 
we  do  not  as  yet  understand  perfectly  the  mysteries  of  the  sap  flow.  In 
1903,  the  scientists  at  the  Vermont  Experiment  Station  did  some  very 


Tree  Study 


739 


remarkable  work  In  clearing  up  the  mysteries  of  sap  movement.  Their 
results  were  published  in  their  Bulletins  103  and  105,  which  are  very 
interesting  and  instructive. 

The  starch  which  is  changed  to  sugar  in  the  sap  of  early  spring  was  made 
the  previous  season  and  stored  within  the  tree.  If  the  foliage  of  the  tree  is 
injured  by  caterpillars  one  year,  very  little  sugar  can  be  made  from  that  tree 
the  next  spring,  because  it  has  been  unable  to  store  enough  starch  in  its  sap- 
wood  and  in  the  outer  ray-cells  of  its  smaller  branches  to  make  a good 
supply  of  sugar.  During  the  latter  part  of  winter,  the  stored  starch  dis- 
appears, being  converted  into 
tree-food  in  the  sap,  and  then 
begins  that  wonderful  surgin  g 
up  and  down  of  the  sap  tide 
During  the  first  part  of  a 
typical  sugar  season,  more 
sap  comes  from  above  down 
than  from  below  up ; toward 
the  end  of  the  season,  during 
poor  sap  days,  there  is  more 
sap  coming  up  from  below 
than  down  from  above.  The 
ideal  sugar  weather  consists 
of  warm  days  and  freezing 
nights.  This  change  of  tem- 
perature between  day  and 
night  acts  as  a pump.  Dur- 
ing the  day  when  the  branches 
of  the  tree  are  warmed,  the 
pressure  forces  into  the  hole 
bored  into  the  trunk  all  the 
sap  located  in  the  adjacent 
cells  of  the  wood.  Then  the 
suction  which  follows  a freez- 
ing night  drives  more  sap  into 
those  cells,  which  is  in  turn 
forced  out  when  the  top  of  the  tree  is  again  warmed.  The  tree  is  usually 
tapped  on  the  south  side,  because  the  action  of  the  sun  and  the  consequent 
temperature-pump  more  readily  affects  that  side. 

“Tapping  the  sugar  bush”  are  magical  words  to  the  country  boy  and 
girl.  Well  do  we  older  folk  remember  those  days  in  March  when  the  south 
wind  settled  the  snow  into  hard,  marblelike  drifts,  and  the  father  would 
say,  “We  will  get  the  sap-buckets  down  from  the  stable  loft  and  wash  them, 
for  we  shall  tap  the  sugar-bush  soon.”  In  those  days  the  buckets  were 
made  of  staves  and  were  by  no  means  so  easily  washed  as  are  the  metal 
buckets  of  to-day.  Well  do  we  recall  the  sickish  smell  of  musty  sap  that 
greeted  our  nostrils,  when  we  poured  in  the  boiling  water  to  clean  those  old 
brown  buckets.  Previously  during  the  winter  evenings,  we  all  had  helped 
fashion  sap-spiles  from  stems  of  sumac.  With  buckets  and  spiles  ready 
when  the  momentous  day  came,  the  large,  iron  caldron  kettle  was  loaded 
on  a stoneboat  together  with  a sap-cask,  log-chain,  ax  and  various  other 
utensils,  and  as  many  children  as  could  find  standing  room;  then  the  oxen 
were  hitched  on  and  the  procession  started  across  the  rough  pasture  to  the 


740  Handbook  of  Nature-Study 

woods,  where  it  eventually  arrived  after  numerous  stops  for  reloading  almost 
everything  but  the  kettle. 

When  we  came  to  the  boiling  place,  we  lifted  the  kettle  into  position  and 
flanked  it  with  two  great  logs  against  which  the  fire  was  to  be  kindled. 
Meanwhile  the  oxen  and  stoneboat  returned  to  the  house  for  a load  of 
buckets.  The  oxen  blinking,  with  bowed  heads,  or  with  noses  lifted  aloft 
to  keep  the  underbrush  from  striking  their  faces,  “gee’d  and  haw’d”  up  hill 
and  down  dale  through  the  woods,  stopping  here  and  there  while  the  men 
with  augers  bored  holes  in  certain  trees  near  other  holes  which  had  bled 
sweet  juices  in  years  gone  by.  When  the  auger  was  withdrawn,  the  sap 
followed  it,  and  enthusiastic  young  tongues  met  it  half  way,  though  they 
received  more  chips  than  sweetness  therefrom ; then  the  spiles  were  driven 
in  with  a wooden  mallet. 

The  next  day  after  “tapping,”  those  of  us  large  enough  to  wear  the  neck- 
yoke  donned  cheerfully  this  badge  of  servitude  and  with  its  help  brought 

pails  of  sap  to  the  kettle,  and  the 
“boiling”  began.  As  the  evening 
shades  gathered,  how  delicious  was 
the  odor  of  the  sap  steam,  per- 
meating the  woods  farther  than 
the  shafts  of  firelight  pierced  the 
gloom ! How  weird  and  delightful 
was  this  night  experience  in  the 
woods!  And  how  cheerfully  we 
swallowed  the  smoke  which  the 
contrary  wind  seemed  ever  to  turn 
toward  us!  We  poked  the  fire  to 
send  the  sparks  upward,  and  now 
and  then  added  more  sap  from  a 
barrel,  and  removed  the  scum  from 
the  boiling  liquid  with  a skimmer 
thrust  into  the  cleft  of  a long  stick 
for  a handle.  As  the  evening  wore 
on,  we  drew  closer  to  each  other 
as  we  told  stories  of  the  Indians, 
bears,  panthers  and  wolves  which 
had  roamed  these  woods  when  our 
father  was  a little  boy ; and  came 
to  each  of  us  a disquieting  suspicion 
that  perhaps  they  were  not  all  gone 
yet,  for  everything  seemed  possible 
in  those  night-shrouded  woods;  and 
our  hearts  suddenly  “jumped  into  our  throats”  when  near  by  there 
sounded  the  tremulous,  blood-curdling  cry  of  the  screech  owl. 

After  about  three  days  of  gathering  and  boiling  sap,  came  the  “siruping 
down.”  During  all  that  afternoon  we  added  no  more  sap  and  we  watched 
carefully  the  tawny,  steaming  mass  in  the  kettle;  when  it  threatened  to 
boil  over,  we  threw  in  a thin  slice  of  fat  pork  which  seemed  to  have  some 
mysterious  calming  influence.  The  odor  grew  more  and  more  delicious  and 
presently  the  sirup  was  pronounced  sufficiently  thick.  The  kettle  was 
swung  off  the  logs  and  the  sirup  dipped  through  a cloth  strainer  into  a 
carrying-pail.  Oh,  the  blackness  of  the  residue  left  on  that  strainer!  But

it  was  clean  woods-dirt  and  never  destroyed  our  faith  in  the  maple-sugar, 
any  more  than  did  the  belief  that  our  friends  were  made  of  dirt  destroy  our 
friendship  for  them.  The  next  day  our 
interests  were  transferred  to  the  house 
where  we  “sugared  off.”  There  we 
boiled  the  sirup  to  sugar  on  the  stove 
and  pouring  it  thick  and  hot  upon  snow 
made  that  most  delicious  of  all  sweets — 
the  maple-wax;  or  we  stirred  it  until 
it  “grained,”  before  we  poured  it  into 
the  tins  to  make  the  “cakes”  of  maple- 
sugar. 

Now  the  old  stave  bucket  and  the 
sumac  spile  are  gone;  in  their  place 
the  patent  galvanized  spile  not  only 
conducts  the  sap  but  holds  in  place  a 
tin  bucket  carefully  covered.  The  old 
caldron  kettle  is  broken,  or  lies  rusting 
in  the  shed.  In  its  place,  in  the  new- 
fangled sugar-houses,  are  evaporating 
vats,  set  over  furnaces  with  chimneys. 

But  we  may  as  well  confess  that  the 
maple-sirup  of  to-day  seems  to  us  a 
pale  and  anaemic  liquid,  lacking  the 
delicious  flavor  of  the  rich,  dark  nectar 
which  we,  with  the  help  of  cinders, 
smoke  and  various  other  things,  brewed  of  yore  in  the  open  woods. 

LESSON  CXC 
The  Sugar  Maple 
Leading  thought — The  sugar 
maple  grows  very  rapidly,  and 
is  therefore  a useful  shade 
tree.  Its  wood  is  used  for 
many  purposes,  and  from  its 
sap  is  made  a delicious  sugar. 

Method — This  study  of  the 
maple  should  be  done  by  the 
pupils  out  of  doors,  with  a tree 
to  answer  the  questions.  The 
study  of  the  leaves,  blossoms 
and  fruit  may  be  made  in 
the  schoolroom.  The  maple 
is  an  excellent  subject  for 
Lesson  CLXXXVIII.  The 
observations  should  begin  in 
the  fall  and  continue  at 
intervals  until  June.

tree  ? Do  the  same  plants  grow  there  as  in  the  open  field  ? 

5.  Does  your  maple 
get  its  autumn  colors 
all  at  once,  or  on  one  or 
two  branches  first?  At 
what  time  do  you  see 
the  first  autumn  colors 
on  your  tree  ? When  is 
it  completely  clothed  in 
its  autumn  dress?  Is 
it  all  red  or  all  yellow, 
or  mixed?  If  it  is  yel- 
low this  year  do  you 
think  it  will  be  red  next

kind  of  weather  is  the  best  for 
causing  sap  flow?  Do  you  sup-

from  the  root  to  the  tree  and  the 
branches,  or  that  coming  down 
from  the  branches  to  the  root 
which  flows  into  the  bucket  ? 
Why  do  we  not  make  maple-

THE  AMERICAN  ELM 


Teacher's  Story 


LTHOUGH  the  American  elm  loves  moist  woods, 
it  is  one  of  those  trees  that  enjoys  gadding;  and 
without  knowing  just*  how  it  has  managed  to  do 
it,  we  can  see  plainly  that  it  has  planted  its  seeds 
along  fence  corners,  and  many  elms  now  grace 
, our  fields  on  sites  of  fences  long  ago  laid  low. 
Because  of  its  beautiful  form  and  its  rapid 
growth,  the  elm  has  been  from  earliest  times  a 
favorite  shade  tree  in  the  Eastern  and  Middle 
States.  Thirty  years  after  being  planted,  the 
elms  on  the  Cornell  Campus  clasped  branches 
across 

the  avenues;  and  the  beauty  of 
many  a village  and  city  is  due 
chiefly  to  these  graceful  trees  of 
bounteous  shade.  Moreover  the 
elm  is  at  no  time  more  beautiful 
than  when  it  traces  its  flowing 
lines  against  the  background  of 
snow  and  gray  horizon.  Whether 
the  tree  be  shaped  like  a vase  or 
a fountain,  the  trunk  divides 
into  great  uplifting  branches, 
which  in  turn  divide  into 
spray  that  oftentimes  droops 
gracefully,  as  if  it  were  made  pur- 
posely to  sustain  from  its  fine  tips 
the  woven  pocket-nest  of  the 
oriole.  No  wonder  this  bird  so 
often  chooses  the  elm  for  its  roof- 
tree! 

In  winter,  the  dark,  coarsely- 
ridged  bark  and  the  peculiar, 
wiry,  thick  spray,  as  well  as  the 
characteristic  shape  of  the  tree 
reveal  to  us  its  identity;  it  also

has  a peculiar  habit  of  growing  its  short  branches  all  the  way  down  its 
trunk,  making  it  look  as  if  it  were  entwined  with  a vine.  The  elm  leaf, 
although  its  ribs  are  straight  and  simple,  shows  a little  quirk  of  its  own  in 
the  uneven  sides  of  its  base  where  it  joins  the  petiole',  it  is  dark  green 
and  rough  above,  light  green  and  somewhat  rough  below;  but  this  leaf  is 
rough  only  when  stroked  in  certain  directions,  while  the  leaf  of  the  slippery 
elm  is  rough  whichever  way  it  may  be  stroked.  The  leaf  has  the  edges  saw- 
toothed, which  are  in  turn  toothed;  the  petiole  is  short.  The  leaf  comes 
out  of  the  bud  in  the  spring  folded  like  a little  fan ; but  before  the  fans 
are  opened  to  the  spring  breezes,  the  elm  twigs  are  furry  with  reddish 
green  blossoms.  The  blossom  consists  of  a calyx  with  an  irregular 
number  of  lobes,  and  for  every  lobe,  a stamen  which  consists  of  a thread- 
like filament  from  which  hangs  a bright  red  anther ; at  the  center  is  a two- 
celled  pistil  with  two  light  green  styles.  These  blossoms  appear  in  March 
or  early  April,  before  the  leaves. 

When  full-grown  the  fruit  hangs  like  beaded  fringe  from  the  twigs.  The 
seed  is  flat  and  has  a wide,  much  veined  margin  or  wing,  notched  at  the  tip 
and  edged  with  a white  silken  fringe ; the  seed  is  at  the  center,  wrinkled  and 
flat.  Each  seed  shows  at  its  base  the  old  calyx  and  is  attached  by  a slender 
threadlike  stem  to  the  twig  at  the  axils  of  last  year’s  leaves.  A little  later 
the  lusty  breezes  of  spring  break  the  frail  threads  and  release  the  seeds, 
although  few  of  them  find  places  fit  for  growth. 

The  elm  roots 
are  water  hunters 
and  extend  deep 
into  the  earth;  they 
will  grow  towards 
water,  seeming  to 
know  the  way.  The 
elm  heart-wood  is 
reddish,  the  sap- 
wood  being  broad 
and  whitish  in  color ; 
the  wood  is  very 
tough  because  of 
theinterlaced  fibers, 
and  therefore  very 
hard  to  split.  It  is 
used  for  cooperage, 
wheel  hubs,  sad- 
dlery, and  is  now 
used  more  exten- 
sively for  furniture ; 
its  grain  is  most 
ornamental.  It  is 
fairly  durable  as  posts,  but  perhaps  the  greatest  use  of  all  for  the 
tree  is  for  shade.  The  slippery  elm  is  much  like  the  white  elm, 
except  that  its  inner  bark  is  very  mucilaginous,  and  children  love  to 
chew  it.  The  cork  elm  has  a peculiar  corky  growth  on  its  branches, 
giving  it  a very  unkempt  look.  The  wahoo,  or  winged  elm,  is  a small 
tree,  and  its  twigs  are  ornamented  on  each  side  by  a corky  layer.  The 
English  elm  has  a solid,  round  head,  very  different  from  that  of  our  graceful 


Elm  blossoms.

species.  The  elms  are  long-lived,  some  living  for  centuries.  The  Wash- 
ington elm  in  Cambridge,  and  the  William  Penn  elm  in  Philadelphia, 
which  now  has  a monument  to  mark  its  place,  were  famous  trees.

LESSON  CXCI 
The  Elm 

Leading  thought — The  elm  has  a peculiarly  graceful  form,  which  makes  it 
of  value  as  a shade  tree.  It  grows  best  in  moist  locations.  Its  wood  is 
very  tough. 

Method — This  work  should  be  begun  in  the  fall  with  the  study  of  the 
shape  of  the  tree  and  its  foliage.  Sketches  should  be  made  when  the  tree  is 
clothed  in  autumn  tints,  and  later  it  should  be  sketched  again  when  its 
branches  are  naked.  Its  blossoms  should  be  studied  in  March  and  April 
and  its  seeds  in  May. 

Observations — i . Where  does  the  elm  grow  ? Does  it  thrive  where  there 
is  little  water?  What  is  the  usual  shape  of  the  elm ? How  does  the  trunk 
divide  into  branches  to  make  this  shape  possible  ? What  is  the  shape  of  the 
larger  elms  ? Describe  the  spray.  Describe  the  elm  bark.  How  can  you 
tell  the  elm  from  other  trees  in  winter  ? 

2.  Study  the  elm  leaf.  What  is  its  form?  What  kind  of  edges  has  it? 
How  large  is  it  ? What  is  the  difference  in  appearance  and  feeling  between 
the  upper  and  lower  sides  ? Are  the  leaves  rough  above  whichever  way  you 
stroke  them  ? If  a leaf  is  folded  lengthwise  are  the  two  halves  exactly  alike  ? 
How  are  the  leaves  arranged  on  the  twig  ? What  is  their  color  above  and 
below  ? Describe  the  leafy  growth  along  the  trunk. 

3 . What  is  the  color  of  the  elm  tree  in  autumn  ? Make  a sketch  of  the 
elm  tree  you  are  studying. 

4-  What  sort  of  roots  has  the  elm?  Do  they  grow  deep  into  the  earth? 
What  is  the  character  of  its  wood?  Is  it  easy  to  split ? Why?  What  are 
the  chief  uses  of  the  elm?

THE  OAK 
Teacher's  Story 

HE  symbol  of  rugged  strength  since  man  first 
gazed  upon  its  noble  proportions,  the  oak  more 
than  other  trees  has  been  entangled  in  human 
myth,  legend  and  imagination.  It  was  regarded 
as  the  special  tree  of  Zeus  by  the  Greeks. 
Virgil  sang  of  it  thus : 

“Full  in  the  midst  of  his  own  strength  he  stands 
Stretching  his  brawny  arms  and  leafy  hands, 
His  shade  protects  the  plains,  his  head  the  hills 
commands.” 

While  in  primitive  England  the  strange  worship 
of  the  Druids  centered  around  it. 

Although  the  oak  is  a tree  of  grandeur  when  its  broad  branches  are 
covered  with  leafage,  yet  it  is  only  in  winter  when  it  stands  stripped  like  an 
athlete  that  we  realize  wherein  its  supremacy  lies.  Then  only  can  we 
appreciate  the  massive  trunk  and  the  strong  limbs  bent  and  gnarled  with 
combating  the  blasts  of  centuries.  But  there  are  oaks  and  oaks,  and  each 
species  fights  time  and 
tempest  in  his  own 
peculiar  armor  and  in 
his  own  way.  Many  of 
the  oaks  achieve  the 
height  of  eighty  to  one 
hundred  feet.  The  great 
branches  come  off  the 
sturdy  trunk  at  wide 
angles,  branches  that 
may  be  crooked  or 
gnarled  but  are  ever  long 
and  strong;  the  smaller 
branches  also  come  off 
at  wide  angles,  and  in 
turn  bear  angular  in- 
dividual spray  all  of  White  oak  leaves  and  acorn.

which,  when  covered  with  leaves,  make  the  broad,  rounded  head  which 
characterizes  this  tree.  The  oaks  are  divided  into  two  classes  which  the 
children  soon  learn  to  distinguish,  as  follows : 

A.  The  white  oak  group , the  leaves  of  which  have  rounded  lobes  and 
are  rough  and  light-colored  below ; the  wood  is  light-colored,  the  acorns  have 


sweet  kernels  and  mature  in  one  year,  so  that  there  are  no  acorns  on  the 
branches  in  winter.  To  this  class  belong  the  white,  chestnut,  bur,  and 
post  oaks. 

AA.  The  black  oak  group,  the  leaves  of  which  are  nearly  as  smooth  below 
as  above,  and  have  angular  lobes  ending  in  sharp  points.  The  bark  is  dark 
in  color,  the  acorns  have  bitter  kernels  and  require  two  years  for  maturing, 
so  that  they  may  be  seen  on  the  branches  in  winter.  To  this  group  belong 
the  red,  scarlet,  Spanish,  pin,  scrub,  black-jack,  laurel  and  willow  oaks. 

There  is  a great  variation  in  the  shape  of  the  leaves  on  the  same  tree,  and 
while  the  black,  the  red  and  the  scarlet  oaks  are  well-marked  species,  it  is 
possible  to  find  leaves  on  these  three  different  trees  which  are  similar  in 
shape.  Oaks  also  hybridize,  and  thus  their  leaves  are  a puzzle  to  the 
botanist;  but  in  general,  the  species  can  be  determined  by  any  of  the  tree 
books,  and  the  pupils  should  learn  to  distinguish  them. 

The  acorns  and  their  scaly  saucers  are  varied  in  shape,  and  are  a delight 
to  children  as  well  as  to  pigs.  The  great  acorns  of  the  red  oak  are  made

is  the  average 
age  of  most  oaks, 
yet  a scarlet  oak 
of  my  acquain- 
tance is  about 
four  hundred 
years  old,  and 
there  are  oaks 
still  living  in 
England  which 
were  there  when 
William,  the 
Conquerer  came. 

The  famous 
Wadsworth  Oak 
at  Geneseo.N.Y.

ferenceof  twenty 


into  cups  and  saucers  by  the  girls, 
and  those  of  the  scarlet  oak  into 
tops  by  the  boys.  The  white 
oaks  turn  a rich  wine-color  in  the 
autumn,  while  the  bur  and  the 
chestnut  are  yellow.  The  red 
oak  is  a dark,  wine-red;  the  black 
oak  russet,  and  the  scarlet  a deep 
and  brilliant  red.  When  the  oak 
leaves  first  come  from  the  buds 
in  the  spring,  they  are  soft  and 
downy  and  drooping,  those  of  the 
red  and  scarlet  being  reddish,  and 
those  of  the  white,  pale  green 
with  red  tints.  Thoreau  says  of 
them,  “They  hang  loosely,  flac- 
idly  down  at  the  mercy  of  the 
wind,  like  a new-born  butterfly 
or  dragonfly.” 

The  pollen-bearing  flowers  are 
like  beads  on  a string,  several 
strings  hanging  down  from  the 
same  point  on  the  twig,  making  a 
fringe,  and  they  are  attractive  to 
the  eye  that  sees.  The  pistillate 
flowers  are  inconspicuous,  at  the 
axils  of  the  leaves,  and  have 
irregular  or  curved  stigmas ; they 
are  on  the  same  branch  as  the 
pollen-bearing  flowers. 

The  oak  is  long-lived;  it  does 
not  produce  acorns  until  about 
twenty  years  of  age  and  requires

great  number  of  roots  near 
the  surface  which  act  as 
braces,  and  their  large  and 
luxurious  heads. 

Oak  wood  is  usually  heavy, 
very  strong,  tough  and  coarse. 
The  heart  is  brown,  the  sap- 
wood  whitish.  It  is  used  for 
many  purposes — ships,  fur- 
niture, wagons,  cars,  cooper- 
age, farm  implements,  piles, 
wharves,  railway  ties,  etc. 
The  white  and  live  oaks  give 
the  best  wood.  Oak  bark  is 
used  extensively  for  tanning. 

LESSON  CXCII 
The  Oaks 


Leading  thought — The  oak  tree  is  the  symbol  of  strength  and  loyalty. 
Let  us  study  it  and  see  what  qualities  in  it  have  thus  distinguished  it. 

Method — Any  oak  tree  may  be  used  for  this  lesson ; but  whatever  species 
is  used,  the  lesson  should  lead  to  the  knowledge  of  all  the  species  of  oaks  in 
the  neighborhood.  The  tree  should  be  sketched,  essays  concerning  the 
connection  of  the  oak  with  human  history  should  be  written,  while  the

leaves  and  acorns  may  be  brought  into  the  schoolroom  for  study.  Use 
Lesson  CLXXXIX  for  a study  of  leaves  of  all  the  oaks  of  the  neighborhood. 

Observations — i.  Describe  the  oak 
tree  which  you  are  studying.  Where 
is  it  growing?  What  shape  is  its 
head?  How  high  in  proportion  to 
the  head  is  the  trunk?  What  is  the 
color  and  character  of  its  bark? 

Describe  its  roots  as  far  as  you  can 
see.  Are  the  branches  straight  or 
crooked?  Delicate  or  strong?  Is 
the  spray  graceful  or  angular  ? Cup  and  saucer  made  from  the  acorns  of 

2.  What  is  the  name  of  your  oak  red  oak 

tree  ? What  is  the  color  of  its  foliage 

in  autumn?  Find  three  leaves  from  your  tree  which  differ  most  widely  in 
form,  and  sketch  them  or  make  leaf  prints  of  them  for  your  note-book. 
Does  the  leaf  have  the  lobes  rounded,  or  angular  and  tipped  with  sharp 
points?  Is  the  leaf  smooth  on  the  lower  side  or  rough?  Is  there  much 
difference  in  color  between  the  upper  and  the  lower  side  ? 

3.  Describe  the  acorns  which  grow  on  your  oak.  Has  the  acorn  a 
stem,  or  is  it  set  directly  on  the  twig.  How  much  of  the  acorn  does  the  cup 
cover?  Are  the  scales  on  the  cup  fine  or  coarse?  Is  the  cup  rounded  in- 
wards at  its  rim  ? What  is  the  length  of  the  acorn  including  the  cup  ? The 
diameter?  Are  there  acorns  on  your  oak  in  winter?  If  so,  why?  Is  the 
kernel  of  the  acorn  sweet  or  bitter?  Plant  an  acorn  and  watch  it  sprout. 

4.  Read  all  the  stories  you 
can  find  about  oak  trees,  and 
write  them  in  your  note-book. 

5.  How  great  an  age  does  the 
oak  attain?  Describe  how  the 
country  round  about  looked  when 
the  oak  tree  you  are  studying 
was  planted. 

6.  How  many  kinds  of  oaks 
do  you  know  ? What  is  the 
difference  in  leaves  between  the 
white  and  the  black  oak  groups? 
What  is  the  difference  in  the 
length  of  time  required  for  the 
acorns  to  mature  in  these  two 
groups?  The  difference  in  taste 
of  the  acorns  ? The  difference  in 
the  general  color  of  the  bark? 
Why  is  the  chestnut  oak  an 
exception  to  this  latter  rule  ? 

7.  How  do  the  oak  leaves 
look  when  they  first  come  out  of 
the  bud  in  spring?  What  is  the 
color  of  the  tree  covered  with  new 
leaves?  When  does  your  oak

THE  SHAGBARK  HICKORY 
Teacher's  Story 

‘OW  pathetically  the  untidy  bark  of  this  dignified 
tree  suggests  the  careless  raiment  of  a great  man! 
The  shagbark  is  so  busy  being  something  worth 
while  that  it  does  not  seem  to  have  time  or  energy 
to  clothe  itself  in  tailor-made  bark,  like  the  beech, 
the  white  ash  and  the  basswood.  And  just  as  we 
^ like  a great  man  more  because  of  his  n egligence  to 

fashion’s  demands,  so  do  we  esteem  this  noble  tree, 
and  involuntarily  pay  it  admiring  tribute  as  we 
===r  note  its  trunk  with  the  bark  scaling  off  in  long, 
thin  plates  that  curve  outward  at  the  top  and  bot- 
tom and  seem  to  be  only  slightly  attached  at  the  middle. 

In  general  shape,  the  shagbark  resembles  the  oak;  the  lower  branches 
are  large  and,  although  rising  as  they  leave  the  bole,  their  tips  are  deflected; 
and,  for  their  whole  length,  they  are  gnarled  and  knotted  as  if  to  show  their 
strength.  The  bark  on  the  larger  branches  may  be  scaly  toward  their  bases 
but  above  is  remarkably  smooth.  The  spray  is  angular  and  extends  in 
almost  every  direction.  The  leaves,  like  those  of  other  hickories,  are  com- 
pound. There  are  generally  five  leaflets,  but  sometimes  only  three  and 
sometimes  seven.  The  basal  pair  is  smaller  than  the  others.  The  hickory 
leaves  are  borne  alternately  on  the  twig,  and  from  this  character  the  hickory 
may  be  distinguished  from  the  ashes,  which  have  leaves  of  similar  type,  but 
which  are  placed  opposite  on  the  twigs.  The  shagbark  usually  has  an  un- 
symmetrical  oblong  head ; the  lower  branches  are  usually  shorter  than  the 
upper  ones,  and  the  latter  are  irregularly  placed,  causing  gaps  in  the  foliage. 

The  nut  is  large,  with  a thick,  smooth,  outer  husk  channeled  at  the  seams 
and  separating  readily  into  sections ; the  inner  shell  is  sharply  angled  and 
pointed  and  slightly  flattened  at  the  sides ; the  kernel  is  sweet.  The  winter 
buds  of  the  shagbark  are  large,  light  brown,  egg-shaped  and  downy;  they 
swell  greatly  before  they  expand.  There  are  from  eight  to  ten  bud-scales; 
the  inner  ones,  which  are  red,  increase  to  two  or  three  inches  in  length 
before  the  leaves  unfold,  after  which  they  fall  away.  The  young  branches 
are  smooth,  soft,  delicate  in  color,  and  with  conspicuous  leaf  scars. 

The  hickory  bears  its  staminate  and  pistillate  flowers  on  the  same  tree. 
The  pollen-bearing  flowers  grow  ac  the  base  of  the  season’s  shoots  in  slender, 
pendulous,  green  catkins,  which  occur  usually  in  clusters  of  three  swinging 
from  a common  stem.  The  pistillate  flowers  grow  at  the  tips  of  the  season’s 
shoots  singly  or  perhaps  two  or  three  on  a common  stem.  In  the  shagbark 
the  middle  lobe  of  the  staminate  calyx  is  nearly  twice  as  long  as  the  other 
two,  and  is  tipped  with  long  bristles ; it  usually  has  four  stamens  with  yellow 
anthers;  its  pistillate  calyx  is  four-toothed  and  hairy,  and  has  two  large, 
fringed  stigmas. 

The  big  shagbark,  or  king  nut,  is  similar  to  the  shagbark  in  height, 
manner  of  growth,  and  bark.  However,  its  leaves  have  from  seven  to  nine 
leaflets,  which  are  more  oblong  and  wedgelike  than  are  those  of  the  shag- 
bark; they  are  also  more  downy  when  young  and  remain  slightly  downy 
beneath.  The  nut  is  very  large,  thick-shelled,  oblong,  angled,  and  pointed 
at  both  ends.  The  kernel  is  large  and  sweet  but  inferior  in  flavor  to  the 
smaller  shagbark.  The  big  shagbark  has  larger  buds  than  has  the  other. 


756 


Handbook  of  Nature-Study 


Their  fringy,  reddish  purple,  inner  scales  grow  so  large  that  they  appear 
tuliplike  before  they  fall  away  at  the  unfolding  of  the  leaves. 

Hickoy  wood  ranks  high  in  value;  it  is  light-colored,  close-grained, 
heavy,  and  very  durable  when  not  exposed  to  moisture.  It  is  capable  of 
resisting  immense  strain,  and,  therefore,  it  is  used  for  the  handles  of  spades, 
plows  and  other  tools,  and  also  for  spokes  and  thills  in  carriage-making. 
As  a fuel,  it  is  superior  to  most  woods,  making  a glowing,  hot  and  quite 
lasting  fire. 

LESSON  CXCIII 
The  Shagbark 

Leading  thought — The  hickories  are  important  trees  commercially. 
They  have  compound  leaves  which  are  set  alternately  upon  the  twig.  The 
shagbark  can  be  told  from  the  other  hickories  by  its  ragged,  scaling  bark. 

Method — This  lesson  may  be  begun  in  the  winter  when  the  tree  can  be 
studied  carefully  as  to  its  shape  and  method  of  branching.  Later,  the 
unfolding  of  the  leaves  from  the  large  buds  should  be  watched,  as  this  is  a 
most  interesting  process;  and  a little  later  the  blossoms  may  be  studied. 
The  work  should  be  taken  up  again  in  the  fall,  when  the  fruit  is  ripe. 

Observations  Winter  study — i.  What  is  the  general  shape  of  the  whole 
tree?  Are  the  lower  branches  very  large?  At  what  angle  do  the  branches, 
in  general,  grow  from  the  trunk  ? Are  there  many  large  branches  ? 

2.  Where  is  the  spray  borne?  What  is  its  character — that  is,  is  it  fine 
and  smooth,  or  knotted  and  angled?  What  is  its  color? 

3.  Describe  the  bark.  Is  the  bark  on  the  limbs  like  that  on  the  trunk? 

4.  What  is  the  size  and  shape  of  the  buds?  Are  the  buds  greenish- 
yellow,  yellowish  brown,  or  do  they  have  a reddish  tinge? 

5 . Count  the  bud-scales.  Are  they  downy  or  smooth  ? 

Spring  study — 6.  Describe  how  the  hickory  leaf  unfolds  from  its  bud. 
How  is  each  leaflet  folded  within  the  bud? 

7.  Describe  the  long  greenish  catkins  which  bear  the  pollen.  On  what 
part  of  the  twigs  do  they  grow  ? Do  they  grow  singly  or  in  clusters  ? 

8.  Take  one  of  the  tiny,  pollen-bearing  flowers  and  hold  it  under  a lens 
on  the  point  of  a pin.  How  many  lobes  has  the  calyx?  Count  the 
stamens,  and  note  the  color  of  the  anthers. 

9.  Upon  what  part  of  the  twigs  do  the  pistillate  flowers  grow?  How 
many  points  or  lobes  has  the  pistillate  calyx  ? Describe  the  growth  of  the 
nut  from  the  flower. 

Autumn  study — 10.  Does  the  hickory  you  are  studying  grow  in  open 
field  or  wood  ? 

1 1 . Are  the  trunk  and  branches  slender  and  lofty,  or  sturdy  and  wide 
spreading  ? 

12.  Note  the  number  and  shape  of  the  leaflets.  Are  they  slim  and 
tapering,  or  do  they  swell  to  the  width  of  half  their  length?  Are  they  set 
directly  upon  or  are  they  attached  by  tiny  stems  to  the  mid-stem?  Are 
they  smooth  or  downy  on  the  under  side?  Are  the  leaves  set  upon  the 
twigs  alternately  or  opposite  each  other  ? How  are  the  leaflets  set  upon  the 
mid-stem? 

13.  Describe  the  outer  husk  of  the  nut.  Into  how  many  sections  does 
it  open  ? Does  it  cling  to  the  nut  and  fall  with  it  to  the  ground  ? Is  the  nut 
angled  and  pointed,  or  is  it  roundish  and  without  angles?  Is  the  kernel 
sweet  or  bitter?

Chestnut  blossoms. 

Note  the  two  pistillate  flowers  above  the  staminate  catkins. 

THE  CHESTNUT 
Teacher's  Story 

HIS  splendid  tree,  sometimes  reaching  the  height 
of  one  hundred  feet,  seldom  receives  the  admira- 
tion due  to  it,  simply  because  humanity  is  so 
much  more  interested  in  food  than  in  beauty. 
The  fact  that  the  chestnuts  are  sought  so  eagerly 
has  taken  away  from  interest  in  the  appearance 
of  the  tree.  The  chestnut  has  a great  round 
head  set  firmly  on  a handsome  bole,  which  is 
covered  with  grayish  brown  bark  divided  into 
rather  broad,  flat,  irregular  ridges.  The  foliage 
is  superb;  the  long,  slender,  graceful  leaves, 
tapering  at  both  ends,  are  glossy,  brilliant  green  above  and  paler  below; 
and  they  are  placed  near  the  ends  of  the  twigs,  those  of  the  fruiting 
twigs  seeming  to  be  arranged  in  rosettes  to  make  a background 
for  blossom  or  fruit.  The  leaves  are  placed  alternately  and  have 
deeply  notched  edges,  the  veins  extending  straight  and  unbroken  from 
midrib  to  margin;  the  petiole  is  short.  The  leaf  is  like  that  of  the  beech, 


758 


Handbook  of  N atur e-Study 


except  that  it  is  much  longer  and  more  pointed;  it  resembles  in  general 
shape  the  leaf  of  the  chestnut  oak,  except  that  the  edges  of  the  latter  have 
rounded  scallops  instead  of  being  sharply  toothed.  The  burs  appear  at  the 
axils  of  the  leaves  near  the  end  of  the  twig.  Thoreau  has  given  us  a most 
admirable  description  of  the  chestnut  fruit: 

“What  a perfect  chest  the  chestnut  is  packed  in ! With  such  wonderful 
care  Nature  has  secluded  and  defended  these  huts  as  if  they  were  her  most 
precious  fruits,  while  diamonds  are  left  to  take  care  of  themselves.  First,  it 
bristles  all  over  with  sharp,  green  prickles,  some  nearly  a half  inch  long,  like 
a hedgehog  rolled  into  a ball ; these  rest  on  a thick,  stiff,  barklike  rind  one- 
sixteenth  to  one-eighth  of  an  inch  thick,  which  again  is  most  daintily  lined 
with  a kind  of  silvery  fur  or  velvet  plush  one-sixteenth  of  an  inch  thick,  even 
rising  into  a ridge  between  the  nuts,  like  the  lining  of  a casket  in  which  the 
most  precious  commodities  are  kept.  At  last  frost  comes  to  unlock  this 
chest;  it  alone  holds  the  true  key;  and  then  Nature  drops  to  the  rustling 
leaves  a ‘done’  nut,  prepared  to  begin  a chestnut’s  course  again.  Within 
itself  again  each  individual  nut  is  lined  with  a reddish  velvet,  as  if  to  pre- 
serve the  seed  from  jar  and  injury  in  falling,  and  perchance  from  sudden 
damp  and  cold;  and  within  that  a thin,  white  skin  envelops  the  germ. 
Thus,  it  has  lining  within  lining  and  unwearied  care,  not  to  count  closely, 
six  coverings  at  least  before  you  reach  the  contents.” 

The  red  squirrels,  as  if  to  show  their  spite  because  of  the  protection  of 
this  treasure  chest,  have  the  reprehensible  habit  of  cutting  off  the  young 
burs  and  thus  robbing  themselves  of  a rich  later  harvest— which  serves  them 
right.  There  are  usually  two  nuts  in  each  bur,  set  with  flat  sides  together; 
but  sometimes  there  are  three  and  then  the  middle  one  is  squeezed  so  that 
it  has  two  flat  sides.  Occasionally  there  is  only  one  nut  developed  in  a bur 
— an  only  child,  so  well  cared  for  that  it  grows  to  be  almost  globular. 
The  color  we  call  chestnut  is  derived  from  the  beautiful  red-brown  of  the 
polished  shell  of  the  nut,  polished  except  where  the  base  joins  the  bur,  and 
the  apex  which  is  gray  and  downy. 

The  chestnut  is  always  a beautiful  tree,  whether  green  in  summer  or 
glowing  golden  yellow  in  autumn;  but  it  is  most  beautiful  during  late  June 
and  July,  when  covered  with  constellations  of  pale  yellow  stars.  Each  of 
these  stars  is  a rosette  of  the  pollen-bearing  blossoms ; each  ray  consists  of  a 


early  enough,  we  can  see  these  stamens  curled  up  as  they  come 
forth  from  the  tiny,  pale  yellow,  six-lobed  calyx.  One  calyx,  although 
scarcely  one-sixteenth  of  an  inch  across,  develops  from  ten  to  twenty 
of  these  stamens:  these  tiny  flowers  are  arranged  in  knots  along

the  central  thread  of  the  catkin.  No  wonder  it  looks  like  chenille! 
There  are  often  as  many  as  thirty  of  these  catkin  rays  in  the  star 
rosette;  the  lower  ones  come  from  the  axils  of  the  leaves;  but 
toward  the  tips  of  the  twig,  the  leaves  are  ignored  and  the  catkins  have 
possession.  In  one  catkin  I estimated  that  there  were  approximately  2,500 
stamens  developed,  each  anther  packed  with  pollen.  When  we  think  that 
there  may  be  thirty  of  the  catkins  in  a blossom-star,  we  get  a glimmering  of 
the  amount  of  pollen  produced. 

And  what  is  all  this  pollen  for?  Can  it  be  simply  to  fertilize  the  three  or 
four  inconspicuous  flowers  at  the  tip  of  the  twig  beyond  and  at  the  center  of 
the  star?  These  pistillate  flowers  are  little  bunches  of  green  scales  with 
some  short,  white  threads  projecting  from  their  centers;  and  beyond  them  a 
skimpy  continuation  of  the  stem  with  more  little  green  bunches  scattered 
along  it,  which  are  undeveloped  pistillate  blossoryis.  The  one  or  two  flow- 
ers at  the  base  of  the  stem  get  all  the  nourishment  and  the  others  do  not 
develop.  If  we  examine  one  of  these  nests  of  green  scales,  we  find  that 
there  are  six  threads  belonging  to  one  tiny,  green  flower  with  a six-lobed 
calyx ; the  six  threads  are  the  stigmas,  each  one  reaching  out  and  asking  for 
no  more  than  one  grain  of  the  rich  shower  of  pollen. 

Chestnut  wood  is  light,  rather  soft,  stiff,  coarse  and  not  strong.  It  is 
used  in  cabinet  work,  cooperage,  for  telegraph  poles  and  railway  ties. 
When  burned  as  fuel,  it  snaps  and  crackles  almost  equal  to  hemlock. 

LESSON  CXCIV 
The  Chestnut 

Leading  thought — The  chestnut  is  one  of  our  most  beautiful  trees.  We 
should  learn  to  appreciate  it  by  observing  the  beauty  of  its  blossoms  and  of 
its  foliage  when  green  and  when  brilliant  yellow  in  autumn.  Until  the 
chestnut  fruit  is  ripe,  it  is  well  protected  by  its  spiny  bur. 


Handbook  of  N ature-Study 


760 

Method — This  study  may  be  begun  in  the  fall  when  chestnuts  are  ripe. 
Ask  the  boys  to  describe  the  trees  from  which  they  get  this  longed-for 
harvest.  The  leaves,  burs  and  nuts  may  be  studied  in  the  schoolroom. 

Observations — 1.  Where  do  chestnut  trees  grow?  What  is  the  general 
form  of  the  head  of  the  tree?  How  high  is  the  trunk  below  the  branches? 
Do  the  branches  divide  into  fine  twigs  or  spray  at  the  tips  ? 

2.  Sketch  and  describe  a chestnut  leaf,  showing  the  veins,  edges  and 
petiole.  Are  the  leaves  placed  opposite  or  alternate  ? What  is  their  color 
above  and  below?  How  do  the  chestnut  leaves  differ. from  those  of  the 
beech  and  of  the  chestnut  oak  ? What  is  the  color  of  the  chestnut  foliage  in 
autumn? 

3 . Where  on  the  branch  is  the  bur  borne  ? How  does  the  green  chest- 
nut bur  look  ? Why  is  this  prickly  exterior  beneficial  to  the  fruit  ? Does  the

bur  open  easily  when  green?  What  causes  the  chestnut  bur  to  open? 
Into  how  many  lobes  does  it  open?  Describe  an  open  bur  outside  and  in. 

4.  Where  in  the  bur  are  the  chestnuts  set?  How  many  in  one  bur? 
How  can  you  tell  by  the  shape  of  the  chestnut  whether  it  grew  as  a twin  or 
single  in  a bur.  Are  there  ever  three  in  a bur?  If  so,  what  shape  is  the 
middel  one?  Do  the  burs  fall  when  the  chestnuts  are  ripe? 

5.  Take  a single  chestnut.  Describe  its  shape  and  color.  What  is  the 
mark  on  its  large  end?  Describe  the  coloring  and  covering  of  the  tip. 
Open  the  shell  and  note  the  lining.  Describe  how  the  meat  is  finally  pro- 
tected. Can  you  see  where  the  germ  is?  Plant  a chestnut  and  watch  it 
grow. 

6.  Study  the  chestnut  blossom  in  late  June  or  July.  What  kind  of 
blossoms  are  those  which  look  like  yellow  stars  all  over  the  tree  ? Study  one 
of  the  catkins  which  makes  a ray  of  the  star,  and  describe  it.  Can  you  see 
the  anthers  and  the  pollen  ? How  many  of  these  pollen-bearing  flowers  are

on  one  stem?  Where  are  the  pistillate  flowers  which  will  grow  into  young 
chestnuts?  Describe  them. 

7 . How  much  are  chestnuts  worth  per  bushel  ? To  what  uses  is  chest- 
nut timber  put  ? What  is  the  character  of  the  wood  ?

wealth  in  this  world;  and  the  horse-chestnuts, 
brown  and  smooth,  looking  so  appetizing  and  so 
belying  their  looks,  have  been  used  from  time 
immemorial  by  boys  as  legal  tender — a fit  use, 
for  these  handsome  nuts  seem  coined  purposely 
for  boys’  pockets. 

The  horse-chestnut  is  a native  of  Asia 
Minor.  It  has  also  a home  in  the  high  moun- 
tains of  Greece.  In  America,  it  is  essentially  a 
shade  tree.  Its  head  is  a broad  cone,  its  dark 
green  foliage  is  dense  and,  when  in  blossom,  the 
flower  clusters  stand  out  like  little  white 
pyramids  against  the  rich  back-ground 
in  a most  striking  fashion.  “A  pyramid 
of  green  supporting  a thousand  pyra- 
mids of  white”  is  a clever  description  of 
this  tree’s  blossoming.  The  brown  bark 
of  the  trunk  has  a tendency  to  break  into 
plates,  and  the  trunk  is  just  high  enough 
to  make  a fitting  base  for  the  handsome 
head. 

The  blossom  panicle  is  at  the  tip  end 
of  the  twig  and  stops  its  growth  at  that 
point;  the  side  buds  continue  to  grow 
thus  making  a forking  branch.  Each 
blossom  panicle  stands  erect  like  a candle

flame,  and  the  flowers  are  arranged  spirally  around  the  central  stem,  each 
pedicel  carrying  from  four  to  six  flowers.  The  calyx  has  five  unequal  lobes, 
and  it  and  the  stem  are  downy.  Five  spreading  and  unequal  petals 
with  ruffled  margins  are  raised  on  short  claws,  to  form  the  corolla;  seven 
stamens  with  orange  colored  anthers  are  thrust  far  out  and  up  from  the 
flower.  The  blossoms  are  creamy  or  pinkish  white  and  have  purple  or 
yellow  blotches  in  their  throats.  Not  all  the  flowers  have  perfect  pistils. 
The  stigmas  ripen  before  the  pollen,  and  are  often  thrust  forth  from  the 
unopened  flower.  The  flowers  are  fragrant  and  are  eagerly  visited  by 
bumblebees,  honey-bees  and  wasps. 

Very  soon  after  the  blossom  falls,  there  may  be  seen  one  or  two  green, 
prickly  balls  which  are  all  the  fruits  one  flower  cluster  could  afford  to 
mature.  By  October  the  green,  spherical  husk  breaks  open  in  three  parts, 
showing  its  white  satin  lining  and  the  roundish,  shining,  smooth  nut  at  its 
center.  At  first  there  were  six  little  nuts  in  this  husk,  but  all  except  one 
gave  up  to  the  burly  occupant.  The  great,  round,  pale  scar  on  the  nut  is 
where  it  joined  the  husk.  Very  few  American  animals  will  eat  the  nut ; the 
squirrels  scorn  it  and  horses  surely  disown  it. 

In  winter,  the  horse-chestnut  twig  has  at  its  tip  a large  bud  and  looks 
like  a knobbed  antenna  thrust  forth  to  test  the  safety  of  the  neighborhood. 
There  are,  besides  the  great  varnished  buds  at  the  ends  of  the  twigs,  smaller 
buds  opposite  to  each  other  along  the  sides  of  the  twig,  standing  out  stiffly. 
On  each  side  of  the  end  bud,  and  below  each  of  the  others,  is  a horseshoe- 
shaped scar  left  by  the  falling  leaf  of  last  year.  The  “nails”  in  this  horse- 
shoe are  formed  by  the  leafy  fibres  which  joined  the  petiole  to  the  twig.

The  great  terminal  buds  hold  both  leaves  and  flowers.  The  buds  in  winter 
are  brown  and  shining  as  if  varnished ; when  they  begin  to  swell,  they  open, 
displaying  the  silky  gray  floss  which  swaddles  the  tiny  leaves.  The  leaves 
unfold  rapidly  and  lift  up  their  green  leaflets,  looking  like  partly  opened 
umbrellas,  and  giving  the  tree  a very  downy  appearance,  which  Lowell  so 
well  describes : 

“And  gray  hoss-chestnut’s  leetle  hands  unfold 
Softer ’n  a baby’s  be  at  three  days  old.” 

The  leaf,  when  fully  developed,  has  seven  leaflets,  of  which  the  central 
ones  are  the  larger.  They  are  all  attached  around  the  tip  of  the  petiole. 
The  number  of  leaflets  may  vary  from  three  to  nine,  but  is  usually  seven. 
The  leaflets  are  oval  in  shape,  being  attached  to  the  petiole  at  the  smaller 
end ; their  edges  are  irregularly  toothed.  The  veins  are  large,  straight  and 
lighter  in  color;  the  upper  surface  is  smooth  and  dark  green,  the  under  side 
is  lighter  in  color  and  slightly  rough.  The  petiole  is  long  and  shining  and 
enlarges  at  both  ends;  when  cut  across,  it  shows  a woody  outer  part  encas- 
ing a bundle  of  fibres,  one  fiber  to  each  leaflet.  The  places  where  these 
fibers  were  attached  to  the  twig  make  the  nails  in  the  horseshoe  scar.  The 
leaves  are  placed  opposite  on  the  twigs. 

Very  different  from  that  of  the  horse-chestnut  is  the  flowed  of  the  yellow 
or  sweet,  buckeye;  the  calyx  is  tubular,  long  and  five-lobed ; the  two  side 
petals  are  on  long  stalks  and  are  closed  like  spoons  over  the  stamens  and 
anthers ; the  two  upper  petals  are  also  on  long  stalks,  lifting  themselves  up 
and  showing  on  their  inner  surfaces  a bit  of  color  to  tell  the  wandering  bee 
that  here  is  a tube  to  be  explored.  The  flowers  are  greenish  yellow.  The 
flowers  of  the  Ohio  buckeye  show  a stage  between  the  sweet  buckeye  and 
the  horse-chestnut.  The  Ohio  buckeye  is  our  most  common  native  relative 
of  the  horse-chestnut.  Its  leaves  have  five  leaflets  instead  of  seven.  The 
Sweet  buckeye  is  also  an  American  species  and  grows  in  the  Alleghany 
mountains. 

LESSON  CXCV 
The  Horse-Chestnut 

Leading  thought — The  horse-chestnut  has  been  introduced  into  America 
as  a shade  tree  from  Asia  Minor  and  southern  Europe.  Its  foliage  and  its 
flowers  are  both  beautiful. 

Method — This  tree  is  almost  always  at  hand  for  the  village  teacher,  as  it 
is  so  often  used  as  a shade' tree.  Watching  the  leaves  develop  from  the 
buds  is  one  of  the  most  common  of  the  nature-study  lessons.  The  study  of 
the  buds,  leaves  and  fruits  may  be  made  in  school ; but  the  children  should 
observe  the  tree  where  it  grows  and  pay  special  attention  to  its  insect  visi- 
tors when  it  is  in  bloom. 

Observations — 1.  Describe  the  horse-chestnut  tree  when  in  blossom. 
At  what  time  does  this  occur  ? What  is  there  in  its  shape  and  foliage  and 
flowers  which  make  it  a favorite  shade  tree  ? Where  did  it  grow  naturally  ? 
What  relatives  of  the  horse-chestnut  are  native  to  America? 

2.  Study  the  blossom  cluster;  are  the  flowers  borne  on  the  ends  or  on 
the  sides  of  the  twig?  Describe  the  shape  of  the  cluster.  How  are  the 
flowers  arranged  on  the  main  flower  stalk  to  produce  this  form?  Do  the 
flowers  open  all  at  once  from  top  to  bottom  of  the  cluster?  Are  all  the 
flowers  in  the  cluster  the  same  color  ? Are  they  fragrant  ? What  insects 
visit  them?

3.  Take  a single  flower;  describe  the  form  of  the  calyx.  Is  it  smooth 
or  downy  ? Are  the  lobes  all  the  same  size  ? Are  the  petals  all  alike  in  size 
and  shape  ? What  gives  them  the  appearance  of  J apanese  paper  ? Are  any 
connected  together?  Are  they  all  splashed  with  color  alike? 

4.  How  many  stamens  are  there?  Where  do  you  see  them?  What 
color  are  the  anthers?  Search  the  center  of  a flower  for  a pistil  with  its 
green  style.  Do  you  find  one  in  every  flower?  Could  a bee  reach  the 
nectar  at  the  base  of  the  blossom  without  touching  the  stigma?  Could  she 
withdraw  without  dusting  herself  with  pollen? 

5 . How  long  after  the  blossom  does  the  young  fruit  appear  ? How  does 
it  look?  How  many  nuts  are  developed  from  each  cluster  of  blossoms? 
What  is  the  shape  of  the  bur  ? Into  how  many  parts  does  it  open  ? De- 
scribe the  outside ; the  inside.  Describe  the  shape  of  the  nuts,  their  color 
and  markings.  Which  make  the  best  “conquerers,”  those  which  grow 
single  in  the  bur  or  as  twins  ? Open  a nut.  Can  you  find  any  division  in 
the  kernel?  Is  it  good  to  eat? 

Horse-chestnut  Twigs  and  Leaves  in  Spring — 6.  Are  the  buds  on  the 
twigs  nearly  all  the  same  size  ? Where  are  the  larger  ones  situated  ? What 
is  the  color  of  the  buds  ? How  are  the  scales  arranged  on  them  ? Are  they 
shiny  or  dull?  What  do  the  scales  enfold ? Can  you  tell  without  opening 
them  which  buds  contain  flowers  and  which  ones  leaves? 

7.  Describe  the  scars  below  the  buds.  What  caused  them?  What 
marks  are  on  them?  What  made  the  “nails”  in  the  horseshoe?  Has  the 
twig  other  scars  ? How  do  the  ring-marks  show  the  age  of  the  twig  ? Do 
you  see  the  little,  light  colored  dots  scattered  over  the  bark  of  the  twig? 
What  are  they  ? 

8.  Describe  how  the  leaf  unfolds  from  the  bud.  What  is  the  shape  of 
the  leaf?  Do  all  the  leaves  have  the  same  number  of  leaflets?  Do  any  of

them  have  an  even  number?  How  are  the  leaflets  set  upon  the  petiole? 
Describe  the  leaflets,  including  shape,  veins,  edges,  color  above  and  below. 
Is  the  petiole  pliant,  or  stiff  and  strong?  Is  it  the  same  shape  and  size 
throughout  its  length?  Break  a petiole,  is  it  green  throughout?  What 
can  you  see  at  its  center?  Are  the  leaves  opposite  or  alternate?  When 
they  fall,  do  they  drop  entire  or  do  the  leaflets  fall  apart  from  the  stem  ? 

9.  Sketch  the  horse-chestnut  tree. 

10.  How  do  the  flowers  and  leaves  of  the  horse-chestnut  differ  from 
those  of  the  sweet  buckeye  and  of  the  Ohio  buckeye?

THE  WILLOWS 
Teacher's  Story 

They  shall  spring  up  among  the  grass,  as  willows  by  the  water  courses. 

— Isaiah. 

“When  I cross  opposite  the  end  of  Willow  Row  the  sun  comes  out  and  the  trees  are  very 
handsome,  like  a rosette,  pale,  tawny  or  fawn  color  at  base  and  red-yellow  or  orange-yellow 
for  the  upper  three  or  four  feet.  This  is,  methinks,  the  brightest  object  in  the  landscape 
these  days.  Nothing  so  betrays  the  spring  sun.  I am  aware  that  the  sun  has  come  out 
of  the  cloud  just  by  seeing  it  light  up  the  osiers.” — Thoreau. 


HE  willow,  Thoreau  noted,  is  the  golden  osier,  a colonial 
dame,  a descendent  from  the  white  willow  of  Europe. 
It  is  the  most  common  tree  planted  along  streams  to 
confine  them  to  their  channels,  and  affords  an  excellent 
subject  for  a nature-study  lesson.  The  golden  osier  has 
a short  though  magnificent  trunk,  giving  off  tremendous 
branches,  which  in  turn  branch  and  uphold  a mass  of 
golden  terminal  shoots.  But  there  are  many  willows 
besides  this,  and  the  one  who  tries  to  determine  all  the 
species  and  hybrids  must  conclude  that  of  making 
willows  there  is  no  end.  The  species  beloved  by  children 
is  the  pussy  willow  which  is  often  a shrub,  rarely  reach- 
ing twenty  feet  in  height.  It  loves  moist  localities,  and  on  its  branches  in 
early  spring  are  developed  the  silky,  furry  pussies.  These  are  favorite 
objects  for  a nature-study  lesson,  and  yet  how  little  have  the  teachers  or 
pupils  known  about  these  flowers! 

The  willow  pussies  are  the  pollen-bearing 
flowers;  they  are  covered  in  winter  by  a 
brown,  varnished,  double,  tentlike  bract. 

The  pussy  in  full  bloom  shows  beneath  each 
fur-bordered  scale  two  stamens  with  long  fila- 
ments and  plump  anthers;  but  there  are  no 
pistils  in  this  blossom.  The  flowers  which 
produce  seed  are  borne  on  another  tree  entirely 
and  in  similar  greenish  gray  catkins,  but  not 
so  soft  and  furry.  In  the  pistillate  catkin 
each  fringed  scale  has  at  its  base  a pistil 
which  thrusts  out  a Y-shaped  stigma.  The 
question  of  how  the  pollen  from  one  gets  to

the  pistils  of  another  is  a story  which  the  bees 
can  best  tell.  The  willow  flowers  give  the  bees 
almost  their  earliest  spring  feast  and,  when  they 
are  in  blossom,  the  happy  hum  of  the  bees 
working  in  them  can  be  heard  for  some  distance 
from  the  trees.  The  pollen  gives  them  bee 
bread  for  their  early  brood,  and  they  get  their 
honey  supply  from  the  nectar  which  is  pro- 
duced in  little  jug-shaped  glands,  at  the  base 
of  each  pollen-bearing  flower  on  the  “pussy” 
catkin,  and  in  a long  pocket  at  the  base  of  each 
flower  on  the  pistillate  catkin.  So  they  pass 
back  and  forth,  carrying  their  pollen  loads  to 
fertilize  the  stigmas  on  trees  where  there  is  no 
pollen.  It  has  been  asserted  that  the  pussies, 
or  pollen-bearing  flowers,  yield  no  nectar  but 
give  only  pollen,  so  that  the  bee  is  obliged  to 
seek  both  trees  in  order  to  secure  a diet  of 
“balanced  ration;”  but  the  person  who  made 
this  statement  had  never  taken  the  pains  to  look 
at  the  tiny  jugs  over-flowing  with  nectar  found 
at  their  bases. 

In  June  the  willow  seed  is  ripe.  The  catkin 
then  is  made  up  of  tiny  pods,  which  open  like 
milkweed  pods  and  are  filled  with  seed  equipped 
with  balloons.  When  these  fuzzy  seeds  are 
being  set  free  people  say  that  the  willows  “shed 
cotton.” 

Although  the  seed  of  the  willow  is  produced 
in  abundance,  it  is  hardly  needed  for  preserving 
the  species.  Twigs  which  we  place  in  water  to 
develop  flowers  will  also  put  forth  roots;  even 
if  the  twigs  are  placed  in  water  wrong  side  up, 
rootlets  will  form.  A twig  lying  flat  on  moist 
soil  will  push  out  rootlets  along  its  entire  length 
as  though  it  were  a root;  and  shoots  will  grow 
from  the  buds  on  its  upper  side.  This  habit  of 
the  willows  and  the  fact  that  the  roots  are  long, 
strong  and  fibrous  make  these  trees  of  great  use 
as  soil  binders.  There  is  nothing  better  than  a 
thick  hedge  of  willows  to  hold  streams  to  their 
proper  channels  during  floods;  the  roots  reach 
out  in  all  directions,  interlacing  themselves  in 
great  masses,  and  thus  hold  the  soil  of  the  banks 
in  place.  The  twigs  of  several  of  the  species, 
notably  the  crack  and  sand-bar  willows,  are 
broken  off  easily  by  the  wind  and  carried  off 
down  stream,  and  where  they  lodge,  they  take 
root ; thus,  many  streams  are  bordered  by  self- 
planted  willow  hedges. 

The  willow  foliage  is  fine  and  makes  a 
beautiful,  soft  mass,  with  delicate  shadows. 
The  leaf  is  long,  narrow,  pointed  and  slender, 


Tree  Study

with  finely  toothed  edges  and  short  petiole;  the  exact  shape  of  the  leaf, 
of  course,  depends  upon  the  species,  but  all  of  them  are  much  lighter  in 
color  below  than  above.  The  willows  are,  as  a whole,  water  lovers  and 
quick  growers. 

Although  willow  wood  is  soft  and 
exceedingly  light,  it  is  very  tough  when 
seasoned  and  is  used  for  many  things. 

The  wooden  shoes  of  the  European 
peasant,  artificial  limbs,  willowware, 
and  charcoal  of  the  finest  grain  used  in 
the  manufacture  of  gunpowder,  are  all 
made  from  the  willow  wood.  The 
toughness  and  flexibility  of  the  willow 
twigs  have  given  rise  to  many  indus- 
tries ; baskets,  hampers,  carriage  bodies 
and  furniture  are  made  of  them.  To 
get  these  twigs  the  willow  trees  are  pol- 
larded, or  cut  back  every  year  between 
the  fall  of  the  leaves  and  the  flow  of 
the  sap  in  the  spring.  This  pruning 
results  in  many  twigs.  The  use  of  wil- 
low twigs  in  basketry  is  ancient.  The 
Britons  fought  the  Roman  soldiers  from 
behind  shields  of  basket  work ; and  the 
wattled  huts  in  which  they  lived  were 
woven  of  willow  saplings  smeared  with 
clay.  Salicylic  acid,  used  widely  in 
medicine,  is  made  from  willow  bark, 
which  produces  also  tannin  and  some 
unfading  dyes. 

There  are  many  insect  inhabitants 
of  the  willow,  but  perhaps  the  most 
interesting  is  the  little  chap  which 
makes  a conelike  object  on  the  twig  of 
certain  species  of  willow  growing  along 
our  streams.  This  cone  is  naturally 
considered  a fruit  by  the  ignorant, 
but  we  know  that  the  willow  seeds  are 
grown  in  catkins  instead  of  cones. 

This  willow  cone  is  made  by  a small 
gnat  which  lays  its  egg  in  the  tip  of 
the  twig;  as  soon  as  the  little  grub 
hatches,  it  begins  to  gnaw  the  twig, 
and  this  irritation  for  some  reason  stops 
the  growth.  The  leaves  instead  of  de- 
veloping along  the  stem  are  dwarfed 
and  overlap  each  other.  Just  in  the  center  of  the  cone  at  the  tip  of  the  twig 
the  little  larva  lives  its  whole  life  surrounded  by  food  and  protected  from 
enemies;  it  remains  in  the  cone  all  winter,  in  the  spring  changes  to  a pupa, 
and  after  a time  comes  forth — a very  delicate  little  fly.  The  larva  in  this 
gall  is  very  hospitable.  It  has  its  own  little  apartment  at  the  center  but  does 
not  object  to  having  a tenant  in  its  outer  chambers,  a fact  which  is  taken

advantage  of  by  another  gall-gnat  which  breeds  there  in  large  numbers. 
It  is  well  to  gather  these  cones  in  winter;  examine  one  by  cutting  it  open 
to  find  the  larva,  and  place  others  in  a fruit  jar  with  a cover  so  as  to  see  the 
little  flies  when  they  shall  issue  in  the  spring.  (See  p.  362).  For  supple- 

mentary reading  see  “Outdoor  Studies,”  page  24. 

There  is  another  interesting  winter  tenant  of  willow  leaves,  but  it  is 
rather  difficult  to  find.  On  the  lower  branches  may  be  discovered,  during 
winter  and  spring,  leaves  rolled  lengthwise  and  fastened,  making  elongated 
cups.  Each  little  cup  is  very  full  of  a caterpillar  which  just  fits  it,  the  cater- 
pillar’s head  forming  the  plug  of  the  opening.  This  is  the  partially  grown 
larva  of  the  viceroy  butterfly.  It  eats  off  the  tip  of  the  leaf  each  side  of  the 
midrib  for  about  half  its  length,  fastens  the  petiole  fast  to  the  twig  with  silk, 
then  rods  the  base  of  the  leaf  into  a cup,  lines  it  with  silk  and  backs  into  it, 
there  to  remain  until  fresh  leaves  on  the  willow  in  spring  afford  it  new  food.

LESSON  CXCVI 
The  Willows 

Leading  thought — The  willows  have  their  pollen-bearing  flowers  and 
their  seed-bearing  flowers  on  separate  trees;  the  bees  carry  the  pollen  from 
one  to  the  other.  The  willow  pussies  are  the  pollen-bearing  flowers. 

Method — As  early  in  March  as  is  practicable,  have  the  pupils  gather 
twigs  of  as  many  different  kinds  of  willows  as  can  be  found ; these  should 
be  put  in  jars  of  water  and  placed  in  a warm,  sunny  window.  The  catkins 
will  soon  begin  to  push  out  from  the  bud-scales,  and  the  whole  process 
of  flowering  may  be  watched. 


Tree  Study 


769 


Observations — 1 . How  can  you  tell  the 
common  willow  tree  from  afar?  In  what 
localities  do  these  trees  grow?  What  is 
the  general  shape  of  the  big  willow  ? How 
high  is  the  trunk,  or  bole?  What  sort  of 
bark  has  it?  Are  the  main  branches 
large  or  small?  Do  they  stand  out  at  a 
wide  angle  or  lift  up  sharply?  What 
color  are  the  terminal  shoots,  or  spray  ? 

2.  Are  the  buds  opposite  or  alternate 
on  the  twigs?  Is  there  a bud  at  exactly 
the  end  of  any  twig?  How  many  bracts 
are  there  covering  the  bud  ? 

3.  Which  appear  first,  the  leaves  or 
the  blossoms  ? Study  the  pussies  on  your 
twigs  and  see  if  they  are  all  alike.  Is  one 
kind  more  soft  and  furry  than  the  other? 

Are  they  of  different  colors? 

4.  Take  one  of  the  furry  pussies. 

Describe  the  little  bract,  which  is  like  a 
protecting  hood  at  its  base.  What  color 
is  the  fur?  After  a few  days,  what  color 
is  the  pussy?  Why  does  it  change  from 
silver  color  to  yellow?  Pick  one  of  the 
catkins  apart  and  see  how  the  fur  protects 
the  stamens. 

5.  Take  one  of  the  pussies  which  is 
not  so  furry.  Can  you  see  the  little 
pistils  with  the  Y-shaped  stigmas  set  in 
it?  Is  each  little  pistil  set  at  the  base 
of  a little  scale  with  fringed  edges  ? 

6.  Since  the  pollen-bearing  catkins 
are  on  one  tree  and  the  seed-bearing  cat- 
kins are  on  the  other,  and  since  the  seeds 
cannot  be  developed  without  the  pollen, 
how  is  the  pollen  carried  to  the  pistils? 

For  this  answer,  visit  the  willows  when 
the  pussies  are  all  in  bloom  and  listen. 

Tell  what  you  hear.  What  insects  do 
you  see  working  on  the  willow  blossoms  ? 

What  are  they  after?  Seeds  of  willow. 

7.  What  sort  of  seed  has  the  willow?  Photo  by  Verne  Morton. 

How  is  it  scattered?  Do  you  think  the 

wind  or  water  has  most  to  do  with  planting  willow  seed  ? 

Work  for  May  or  September — 8.  Describe  willow  foliage  and  leaves. 
How  can  you  tell  willow  foliage  at  a distance? 

9.  What  sort  of  roots  has  the  willow?  Why  are  the  willows  planted 
along  the  banks  of  streams?  If  you  wished  to  plant  some  willow  trees  how 
would  you  do  it  ? Would  you  plant  seeds  or  twigs  ? 

10.  For  what  purposes  is  willow  wood  used  ? How  are  the  twigs  used  ? 
Why  are  they  specially  fitted  for  this  use?  What  is  pollarding  a tree?

THE  COTTONWOOD,  OR  CAROLINA  POPLAR 

Teacher's  Story 

HE  sojourner  on  our  western  plains  where  streams 
are  few  and  sluggish,  disappearing  entirely  in 
summer,  soon  learns  to  love  the  cottonwoods, 
for  they  will  grow  and  cast  their  shade  for  men 
and  cattle  where  no  other  tree  could  endure. 
The  cottonwood  may  be  unkempt  and  ragged, 
but  it  is  a tree,  and  we  are  grateful  to  it  for  its 
ability  to  grow  in  unfavorable  situations.  In 
the  Middle  West  it  attains  its  perfection,  al- 
though in  New  York  we  have  some  superb 
specimens — trees  which  are  more  than  one 
hundred  feet  in  height  and  with  majestic 
trunks,  perhaps  five  or  six  feet  through.  The  deep-furrowed,  pale  gray 
bark  makes  a handsome  covering.  The  trunk  divides  into  great  out-swing- 
ing, widely  spaced  branches,  which  bear  a fine  spray  on  their  drooping  ends. 
Sargent  declares  that  at  its  best  the  cottonwood  is  one  of  the  statliest  in- 
habitants of  our  eastern  forests.  The  variety  we  plant  in  cities  we  call  the 
Carolina  poplar,  but  it  is  a cottonwood.  It  is  a rapid  grower,  and  therefore 
a great  help  to  the  “boom  towns”  of  the  West  and  to  the  boom  suburbs  in 
the  East;  although  for  a city  tree  its  weak  branches  break  too  readily  in 
wind  storms  in  old  age.  However,  it  keeps  its  foliage  clean,  the  varnished 
leaves  shedding  the  dust  and  smoke;  because  of  this  latter  quality  it  is  of 
special  use  in  towns  that  burn  soft  coal. 

The  cottonwood  twigs  which  we  gather  for  study  in  the  spring  are 
yellowish  or  reddish,  those  of  last  year’s  growth  being  smooth  and  round, 
while  those  showing  previous  growth  are  angular.  The  buds  are  red-brown 
and  shining,  and  covered  with  resin  which  the  bees  like  to  collect  for  their 
glue.  The  leaf  buds  are  slender  and  sharp-pointed;  the  flower  buds  are 
wider  and  plumper. 

The  two  sexes  of  the  flowers  are  borne  on  separate  trees.  The  trees 
bearing  pollen  catkins  are  so  completely  covered  with  them  that  they 
take  on  a very  furry,  purplish  appearance  when  in  blossom.  These  catkins 
are  from  three  to  five  inches  long  and  half  an  inch  thick,  looking  fat  and 
pendulous ; each  fringed  scale  of  the  catkin  has  at  its  base  a disc  looking 
like  a white  bracket,  from  which  hang  the  reddish  purple  anthers;  these 
catkins  fall  after  the  pollen  is  shed  and  look  like  red  caterpillars  upon  the 
ground. 

The  seed-bearing  flowers  are  very  different ; they  look  like  a string  of 
Jittle,  greenish  beads  loosely  strung.  Each  pistil  is  globular  and  set  in  a 
tiny  cup,  and  it  has  three  or  four  stigmas  which  are  widened  or  lobed;  as 


Tree  Study 


771 


it  matures,  it  becomes  larger  and  darker  green, 
and  the  string  elongates  to  six  or  even  ten 
inches.  The  little  pointed  pods  open  into  two  or 
more  valves  and  set  free  the  seeds,  which  are 
provided  with  a fluff  of  pappus  to  sail  them  off  on 
the  breeze;  so  many  of  the  seeds  develop  that 
every  object  in  the  neighborhood  is  covered  with 
their  fuzz,  and  thus  the  tree  has  gained  its  name 
“cottonwood.” 

The  foliage  of  the  cottonwood  is  like  that  of  other 
poplars,  trembling  with  the  breeze.  The  heavy,  sub- 
circular  leaf  is  supported  on  the  sidewise  flattened 
petiole,  so  that  the  slightest  breath  of  air  sets  it  quak- 
ing; a gentle  breeze  sets  the  whole  tree  twinkling  and 
gives  the  eye  a fascinating  impression  as  of  leaves 
beckoning.  The  leaf  is  in  itself  pretty.  It  is  from 
three  to  five  inches  long,  broad,  slightly  angular  at  the 
base  and  has  a long,  tapering,  pointed  tip.  The  edge 
is  saw-toothed,  and  also  slightly  ruffled  except  near  the 
stem  where  it  is  smooth ; it  is  thick  and  shining  green 
above  and  paler  beneath.  The  long,  slender  petiole 
is  red  or  yellowish,  and  the  leaves  are  placed  alternate 
on  the  twigs. 

In  the  autumn  the  leaves  are  brilliant  yellow.  The 
wood  is  soft,  weak,  fine-grained,  whitish  or  yellowish, 
and  has  a satiny  luster ; it  is  not  durable.  It  is  used 
somewhat  for  building  and  for  furniture,  in  some  kinds 
of  cooperage,  and  also  for  crates  and  woodenware;  but 
its  greatest  use  is  for  making  the  pulp  for  paper. 
Many  newspapers  and  books  are  printed  on  cotton- 
wood paper.  It  is  common  from  the  Middle  States  to 
the  Rocky  Mountains  and  from  Manitoba  to  Texas.

LESSON  CXCVII 
The  Cottonwood 

Leading  thought — The  cottonwood  is  a poplar.  It  grows  rapidly  and 
flourishes  on  the  dry  western  plains  where  other  trees  fail  to  gain  a foothold. 
It  grows  well  in  the  dusty  city,  its  shining  leaves  shedding  the  smoke  and 

dirt. 

Method — Begin  this  study  in  spring  before  the  cottonwoods  bloom. 
Bring  in  twigs  in  February,  give  them  water  and  warmth,  and  watch  the 
development  of  the  catkins.  Afterwards  watch  the  unfolding  of  the  leaves 
and  study  the  tree. 

Observations — 1.  What  is  the  color  of  the  bark  on  the  cottonwood  ? Is 
it  ridged  deeply?  What  is  the  color  of  the  twigs?  Are  they  round  or 
angular,  or  both?  Describe  the  winter  buds  and  bud-scales.  Can  you  tell 
which  bud  will  produce  leaves  and  which  flowers  ? 

2.  Describe  the  catkin  as  it  comes  out.  Has  this  catkin  anthers  and 
pollen,  or  will  it  produce  seed  ? Do  you  think  the  seeds  are  produced  on  the 
same  trees  as  the  pollen? 


Handbook  of  Nature-Study 

3.  Find  a pollen-bearing  catkin.  Describe  the  stamens. 
Can  you  see  anything  but  the  anthers  ? On  what  are  they  set  ? 
What  color  are  they?  What  color  do  they  give  to  the  tree 
when  they  are  in  blossom?  What  happens  to  the  catkins 
after  their  pollen  is  shed? 

4.  Find  a seed-bearing  catkin.  How  long  is  it?  Do  you 
see  why  this  tree  is  called  the  necklace  poplar?  Describe 
the  pistils  which  make  the  beads  on  the  necklace. 

5.  When  do  the  seeds  ripen?  If  you  have  been  near  the  tree,  how  do 
you  know  when  they  are  ripe?  How  long  is  the  catkin  with  the  ripened

seeds?  How  many  balls  on  the  necklace  now?  What  is  the  color?  How 
many  seeds  come  out  of  each  little  pod?  How  are  the  seeds  floated  on  the 
air?  Why  do  we  call  this  tree  “cottonwood?” 

6.  How  large  is  the  largest  cottonwood  that  you  know?  Sketch  it  to 
show  the  shape  of  the  tree.  Are  the  main  branches  large?  Do  they  droop 
at  the  tips? 

7 . How  does  the  foliage  of  the  cottonwood  look  ? Does  it  twinkle  with 
the  wind  ? Examine  the  leaves  upon  a branch  and  see  why  they  twinkle. 
Are  the  petioles  round  or  flat  ? Are  they  flattened  sidewise  or  up  and 
down?  Are  they  stiff  or  slender?  Describe  the  leaves,  giving  their  shape, 


Tree  Study

veins,  edges,  color  and  texture  above  and  below.  Are  the  edges  ruffled  as 
well  as  toothed  ? Is  the  leaf  heavy  ? If  a breeze  comes  along  how  would  it 
affect  such  a heavy,  broad  leaf  on  such  a slender,  thin  petiole?  Blow 
against  the  leaves  and  see  how  they  move?  Do  you  understand,  now,  why 
they  twinkle  ? Can  you  see  why  the  leaves  shed  smoke  and  dust,  when  used 
for  shading  city  streets? 

8.  Why  is  the  cottonwood  used  as  a shade  tree?  Do  you  think  it 
makes  a beautiful  shade  tree?  How  long  does  it  take  it  to  grow?  What 
kind  of  wood  does  it  produce  ? For  what  is  it  used  ?

THE  WHITE  ASH 
Teacher's  Story 

YTHS  and  legends  cluster  about  the  ash  tree. 
It  was,  in  the  Norse  mythology,  the  tree 
“Igdrasil,”  the  tree  of  the  universe,  which  was 
the  origin  of  all  things.  It  is  a pity  that  it 
was  not  the  Tree  of  Life  in  the  Garden  of 
Eden,  for  if  another  myth  is  true,  no  snake  will 
go  near  it  or  cross  its  branches.  There  is  a 
widespread  belief  that  it  draws  lightning,  just 
as  the  beech  repels  the  thunderbolts.  “As 
straight  as  a white  ash  tree”  was  the  highest 
compliment  that  could  be  paid  to  the  young 
pioneer;  so  straight  is  its  fiber  and  so  strong 
its  quality,  that  the  American  Indians  made  their  canoe  paddles  from  it. 

The  ashes  have  the  most  beautiful  bark  in  the  world.  It  is  divided  into 
fine,  vertical  ridges,  giving  the  trunks  the  look  of  being  shaded  with  pencil

lines;  the  bark  smooths  out  on  the  lower  branches.  But  even  more 
characteristic  than  the  bark,  are  the  ash  branches  and  twigs ; the  latter  are 
sparse,  coarse  and  clumsy,  those  of  the  white  ash  being  pale  orange  or  gray 
and  seemingly  warped  into  curves  at  the  ends;  they  are  covered  with 
whitish  gray  dots,  which  reveal  themselves  under  the  lens  to  be  breathing- 
pores. 

The  white  ash  loves  to  grow  in  rich  woods  or  in  rich  soil  anywhere,  even 
though  it  be  shallow;  at  its  best,  it  reaches  the  height  of  130  feet,  with  a 
trunk  six  feet  through.  Its  foliage  is  peculiarly  graceful;  the  leaves  are 
from  eight  to  twelve  inches  long  and  are  composed  of  from  five  to  nine 
leaflets.  The  leaflets  have  little  petioles  connecting  them  with  the  middle 
stem ; in  shape  they  are  ovate  with  edges  obscurely  toothed  or  entire ; the 
two  basal  leaflets  are  smaller  than  the  others  and  the  end  one  largest ; in 
texture,  they  are  satiny,  dark  green  above,  whitish  beneath,  with  feather- 
like veins,  often  hairy  on  the  lower  side.  The  petioles  are  swollen  at  the 
base.  The  leaves  are  set  opposite  upon  the  twig ; except  the  horsechestnut, 
the  ashes  are  our  only  trees  with  compound  leaves  which  have  the  leaves 
opposite.  This  character  alone  readily  distinguishes  the  ashes  from  the 
hickories.  The  autumn  foliage  has  a very  peculiar  color;  the  leaves  are 
dull  purple  above  and  pale  yellow  below ; this  brings  the  sunshine  color  into 
the  shadowy  parts  of  the  tree,  and  gives  a curious  effect  of  no  perspective. 
Notwithstanding  this,  the  autumn  coloring  is  a joy  to  the  artistic  eye  and  is 
very  characteristic. 

The  seeds  of  the  ash  are  borne  in  crowded  clusters;  the  delicate  stem, 
from  three  to  five  inches  long,  is  branched  into  smaller  stems  to  which  are 
joined  two  or  three  keys,  and  often  several  of  these  main  stems  come  from 
the  same  bud  at  the  tip  of  last  year’s  wood  so  that  they  seem  crowded. 
The  seed  is  winged,  the  wing  being 
almost  twice  as  long  as  the  seed 
set  at  its  base.  Thoreau  says: 

“The  keys  of  the  white  ash  cover 
the  trees  profusely,  a sort  of  mul- 
berry brown,  an  inch  and  a half 
long,  and  handsome . ’ ’ The  seeds 
cling  persistently  to  the  tree, 
and  I have  often  observed  them 
being  blown  over  the  surface  of 
the  snow  as  if  they  were  skating 
to  a planting  place. 

The  flowers  appear  in  April  or 
May,  before  the  leaves.  The 
pistillate  flowers  make  an  untidy 
fringe,  curling  in  every  direction 
around  the  twigs.  The  chief 
flower  stem  is  three  to  four  inches 
long,  quite  stout,  pale  green,  and 
from  this  arise  short,  fringed 
stems,  each  carrying  along  its 
sides  the  knobs  on  little  stems — \ 
which  are  the  pistillate  flowers.

ing  off  at  its  own  angle  to  get  its  own  pollen.  The  flower  has  the  calyx 
four-lobed;  the  style  is  long  and  slender  and  is  divided  into  a V-shaped 
purple  stigma. 

The  staminate  flowers  appear  early  in  the  spring,  and  look  like  knobs  on 
the  tips  of  the  coarse,  sparse  twigs;,  they  consist  of  masses  of  thick,  green 
anthers  with  very  short,  stout  filaments;  each  calyx  is  four-lobed.

These  flowers  are  attached  to  a five-branching  stem ; but  the  stem  and  its 
branches  cannot  be  seen  unless  the  anthers  are  plucked  off,  because  they 
hang  in  such  a crowded  mass.  Later  the  leaves  come  out  beyond  them. 

The  leaf  buds  in  winter  are  very  pretty;  they  are  white,  bluntly 
pointed,  with  a pale  gray  half-circle  below,  on  which  was  set  last  year’s 
leaf.  Another  one  of  nature’s  miracles  is  the  bouquet  of  leaves  coming 
from  one  of  the  big  four-parted  terminal  buds,  which  is  made  up  of  four 
scales,  two  of  which  are  longer  and  narrower  than  the  others.  Within  the 
bud  each  little  compound  leaflet  is  folded  like  a sheet  of  paper  lengthwise, 
and  folded  with  the  other  leaflets  like  the  leaves  of  a book;  and  when 
they  first  appear  they  look  like  tiny,  scrawny,  birds’  claws.  But  it  is 


Tree  Study

not  merely  one  pair  of  leaves  that  comes  from  this  bud,  but  many,  each 
pair  being  set  on  a twig  opposite  and  at  right  angles  to  the  next  pair  on 
either  side.  Even  as  many  as  five  pairs  of  these  splendid  compound 
leaves  come  from  this  one  prolific  bud.  As  they  push  out,  the  green  stem 
of  the  new  wood  grows,  thus  spacing  the  pairs  properly  for  the  making 
of  beautiful  foliage. 

LESSON  CXCVIII 
Ash  Trees 

Leading  thought — The  ashes  are  our  most  valuable  timber  trees;  the 
white  ash  is  one  of  the  most  beautiful  and  useful  of  them  all.  It  does  not 
make  forests,  but  it  grows  in  them,  and  its  wood  is  of  great  value  for  many 
things. 

Method — The  pupils  should  all  see  the  tree  where  it  grows.  The  ques- 
tions should  be  given  to  them  for  their  field  note-books.  The  lesson  should 
begin  in  the  fall  and  be  continued  in  the  spring. 

Observations — i.  What  is  there  about  the  bark  of  the  ash  tree  which 
distinguishes  it  from  other  trees  ? Where  does  the  white  ash  grow  ? What 
is  the  height  and  thickness  of  the  ash  tree  you  are  studying  ? 

2 . The  ash  leaf  is  a compound  leaf ; of  how  many  leaflets  is  it  composed  ? 
What  is  the  texture  and  shape  of  the  leaflets?  Describe  the  veins.  Do 
the  leaflets  have  petioles  (petiolules)  ? Are  the  edges  of  the  leaflets  toothed  ? 
Which  of  the  leaflets  is  largest?  Which  smallest?  Is  the  petiole  swollen 
at  the  base?  How  are  the  leaves  arranged  on  the  twigs?  How  does  this 
distinguish  the  ashes  from  all  other  of  our  trees  having  compound  leaves? 
How  do  the  hickories  have  their  leaves  arranged  ? What  color  is  the  ash 
foliage  in  autumn? 

3 . Describe  the  seeds  of  the  ash  and  the  way  they  are  arranged  on  their 
stems.  Where  are  they  placed  on  the  tree?  How  long  do  they  cling? 
How  does  the  snow  help  to  scatter  them? 

4.  When  does  the  white  ash  blossom  ? Are  the  pistillate  and  staminate 
flowers  together  or  separate?  Find  and  describe  them. 

5.  What  are  our  uses  for  ash  timber?  For  what  are  the  saplings  used? 
How  did  the  Indians  use  the  white  ash?  Write  a theme  on  all  the  interest- 
ing things  you  can  find  about  the  ash  trees. 

6.  How  many  species  of  the  ash  trees  do  you  know  ?

A baldwin  apple  tree. 

THE  APPLE  TREE 
Teacher's  Story 

As  the  apple  tree  among  the  trees  of  the  wood , so  is  my  beloved  among  the  sons.  I sat 
down  under  his  shadow  with  great  delight,  and  his  fruit  was  sweet  to  my  taste. 

— The  Song  of  Solomon. 

N old-fashioned  orchard  is  always  a delight  to  those  of  us 
if  who  love  the  picturesque.  The  venerable  apple  tree  with 

0$  its  great  twisted  and  gnarled  branches,  rearing  aloft  its 

rounded  head,  and  casting  its  shadow  on  the  green  turf 
below,  is  a picture  well  worthy  of  the  artist’s  brush. 
And  that  is  the  kind  of  orchard  I should  always  have, 
because  it  suits  me,  just  as  it  does  bluebirds,  downies 
and  chickadees,  as  a place  to  live  in.  However,  if  I 
wished  to  make  money  by  selling  apples,  I should 
need  to  have  an  orchard  of  comparatively  young  trees, 
which  should  be  straight  and  well  pruned,  and  the  ground  beneath  them 
well  cultivated;  for  there  is  no  plant  that  responds  more  generously  to 
cultivation  than  does  the  apple  tree.  In  such  an  orchard,  a few  annual 
crops  might  be  grown  while  the  trees  were  young,  and  each  year  there 
should  be  planted  in  August  or  September  the  seed  of  crimson  clover  or  of 
some  other  good  cover-crop.  This  would  grow  so  as  to  protect  the  ground 
from  washing  during  the  heavy  rains  and  thaws  of  fall  and  winter,  and  in 
the  spring  it  would  be  plowed  under  to  add  more  humus  to  the  soil.

The  apple  originally  came  from  southwestern  Asia  and  the  neighboring 
parts  of  Europe,  but  it  has  been  cultivated  so  long  that  we  have  no  accounts 
of  how  it  began.  The  prehistoric  lake-dwellers  of  Switzerland  ate  this 
fruit.  In  this  country  the  apple  thrives  best  on  clay  loam,  although  it 
grows  on  a great  variety  of  soils ; where  wheat  and  corn  grow,  there  will  the 
apple  also  grow.  In  general,  the  shape  of  the  apple  tree  head  is  rounded  or 
broadly  pyramidal;  however,  this  differs  somewhat  with  varieties.  The 
trunk  is  short  and  rather  stocky,  the  bark  is  a beautiful  soft  gray  and  is 
decidedly  scaly,  flaking  off  in  pieces  which  are  more  or  less  quadrangular. 
The  wood  is  very  fine-grained  and  heavy.  On  this  account  for  many  years 
it  was  used  for  wood-engraving  and  is  also  a favorite  wood  for  wood- 
carving ; it  makes  a most  excellent  fuel.  The  spray  is  fine,  and  while  at  the 
tips  of  the  limbs  it  may  be  drooping  or  horizontal,  it  often  grows  erect  along 
the  upper  sides  of  the  limbs,  each  shoot  looking  as  if  it  were  determined  to 
be  a tree  in  itself.  The  leaves  are  oval,  with  toothed  edges  and  long 
petioles.  When  the  leaves  first  appear  each  has  two  stipules  at  its  base. 
The  shape  of  the  apple  leaves  depends  to  some  extent  upon  the  variety  of 
the  apple. 

It  has  long  been  the  practice  not  to  depend  upon  the  seeds  for  reproduc- 
ing a variety;  for,  since  the  bees  do  such  a large  work  in  pollenating  the 
apple  flowers,  it  would  be  quite  difficult  to  be  sure  that  a seed  would  not  be 
a result  of  a cross  between  two  varieties.  Therefore,  the  matter  is  made 
certain  by  the  process  of  grafting  or  budding.  There  are  several  modes  of 
grafting,  but  perhaps  the  one  in  most  common  use  is  the  cleft-graft.  A

scion  which  is  a twig  bearing  several  buds,  is  cut  from  a tree  of  the  desired 
variety,  and  its  lower  end  is  cut  wedge-shaped.  The  branch  of  the  tree  to 
be  grafted  is  cut  off  across  and  split  down  through  the  end  to  the  depth  of 
about  two  inches ; the  wedge-shaped  end  of  the  scion  is  pressed  into  this  cleft, 
so  that  its  bark  will  come  in  contact  with  the  inner  edge  of  the  bark  on  one 
side  of  the  cleft  branch.  The  reason  for  this  is  that  the  growing  part  of  the 
tree  is  the  cambium  layer,  which  is  just  inside  of  the  bark,  and  if  the  cam- 
bium of  the  scion  does  not  come  in  contact  with  the  cambium  of  the  branch 
they  will  not  grow  together.  After  the  graft  becomes  well-established,  the 
other  branches  of  the  tree  are  cut  off  and  the  tree  produces  apples  only  from 
that  part  of  it  which  grows  from  the  graft.  After  the  scion  has  been  set  in 
the  stock,  all  of  the  wounded  parts  are  covered  with  grafting  wax,  which 
keeps  in  the  moisture  and  keeps  out  disease  germs.

Budding  is  done  on  a similar  principle,  but  in  a different  fashion.  A 
seedling  apple  tree  about  a year  and  a half  old  has  a T-shaped  slit  cut  into 
its  bark;  into  this  suture  a bud,  cut  from  a tree  of  the  desired  variety  is 
inserted,  and  is  bound  in  with  yarn.  The  next  spring  this  tree  is  cut  back 
to  just  above  the  place  where  the  bud  was  set  in,  and  this  bud-shoot  grows 
several  feet;  the  next  year  the  tree  may  be  sold  to  the  orchardist.  Budding 
is  done  on  a large  scale  in  the  nurseries,  for  it  is  by  this  method  that  the 
different  varieties  are  placed  on  the  market. 

Most  varieties  of  apple  trees  should  be  set  forty  feet  apart  each  way.  It 
is  possible,  if  done  judiciously,  to  raise  some  small  crops  on  the  land  with 
the  young  orchard,  but  care  should  be  taken  that  they  do  not  rob  the  trees 
of  their  rightful  food.  The  dwarf  varieties  begin  to  bear  much  sooner  than 
the  others,  but  an  orchard  does  not  come  into  full  bearing  until  after  it  has 
been  planted  fifteen  or  twenty  years,  The  present  practice  is  to  prune  a 
tree  so  that  the  trunk  shall  be  very  short.  This  makes  the  picking  of  the 
fruit  much  easier  and  also  exposes  the  tree  less  to  wind  and  sun-scald. 

There  are  certain  underlying  principles  of  pruning  that  every  child 
should  know:  The  pruning  of  the  root  cuts  down  the  amount  of  food 
which  the  tree  is  able  to  get  from  the  soil.  The  pruning  of  the  top  throws 
the  food  into  the  branches  which  are  left  and  makes  them  more  vigorous. 
If  the  buds  at  the  tips  of  the  twigs  are  pruned  off,  the  food  is  forced  into  the 
side  buds  and  into  the  fruit,  which  make  greater  growth.  Thinning  the 


Tree  Study

branches  allows  more  light  to  reach  down  into  the  tree,  and  gives  greater 
vigor  to  the  branches  which  are  left.  A limb  should  be  pruned  off  smoothly 
where  it  joins  the  larger  limb,  and  there  should  be  no  stump  projecting;  the 
wound  should  be  painted  so  as  not  to  allow  fungus  spores  to  enter. 

We  should  not  forget  that  we  have  a native  apple,  which  we  know  as  the 
thornapple.  Its  low,  broad  head  in  winter  makes  a picturesque  point  along 
the  fences;  its  fine,  thick  spray,  spread  horizontally,  makes  a fit  framework 
for  the  bridal  bouquet  which  will  grow  upon  it  in  June;  and  it  is  scarcely 
less  beautiful  in  autumn,  when  covered  with  the  little,  red  apples  called 
“haws.”  Though  we  may  refrain  from  eating  these  native  apples,  which 
consist  of  a bit  of  sweet  pulp  around  large  seeds,  the  codling-moth  finds 
them  most  acceptable 

LESSON  CXCIX 
The  Apple  Tree 

Leading  thought — The  tree  of  each  variety  of  apple  has  its  own  character- 
istic shape,  although  all  apple  trees  belong  to  one  general  type.  The  variety 
of  the  apple  grown  upon  the  tree  is  not  determined  by  the  kind  of  seed 
which  is  planted  to  produce  the  tree,  but  by  the  process  of  grafting  or 
budding  the  young  tree. 

Method — A visit  to  a large,  well-grown  orchard  in  spring  or  autumn  will 
aid  in  making  this  work  interesting.  Any  apple  tree  near  at  hand  may  be 
used  for  the  lesson. 

Observations — 1.  How  tall  is  the  largest  apple  tree  you  know?  What 
variety  is  it  ? How  old  is  it  ? How  can  you  distinguish  old  apple  trees 
from  young  ones  at  a glance  ? 

2.  Choose  a tree  for  study:  How  thick  is  its  trunk?  What  is  the 
shape  of  its  head?  Does  the  trunk  divide  into  large  branches  or  does  it 
extend  up  through  the  center  of  the  head? 

3.  What  sort  of  bark  has  it ? What  is  the  color  of  the  bark? 

4.  Does  the  spray  stand  erect  or  is  it  gnarled  and  querly?  Does  the 
spray  grow  simply  at  the  ends  of  the  branches  or  along  the  sides  of  the 
branches? 

5.  Are  the  leaves  borne  at  the  tip  of  the  spray?  Are  the  leaves  oppo- 
site or  alternate  ? Describe  or  sketch  an  apple  leaf.  Does  it  have  stipules 
at  its  base  when  it  first  appears  ? 

6 . What  is  the  character  of  apple-tree  wood  ? What  is  it  used  for  ? 

7 . Did  this  tree  come  from  a seed  borne  in  an  apple  of  the  same  variety 
which  it  produces?  What  is  the  purpose  of  grafting  a tree?  What  is  a 
scion?  How  and  why  do  we  choose  a scion?  How  do  we  prepare  a 
branch  to  receive  the  scion?  If  you  should  place  the  scion  at  the  center  of 
the  branch  would  it  grow?  Where  must  it  be  placed  in  order  to  grow? 
How  do  we  protect  the  cut-end  of  the  branch  after  it  is  grafted?  Why? 

8.  What  is  meant  by  the  term  “budding?”  What  is  the  difference 
between  grafting  and  budding?  Describe  the  process  of  budding. 

9.  Where  is  budding  done  on  a large  scale  ? How  do  nurserymen  know 
what  special  varieties  of  apples  their  nursery  stock  will  bear  ? How  old  is  a 
tree  when  it  is  budded?  How  old  when  it  is  sold  to  the  orchardist? 

10.  Why  should  the  soil  around  apple  trees  be  tilled?  Is  this  the  prac- 
tice in  the  best-paying  orchards? 

11.  What  is  often  used  as  a cover  crop  in  orchards?  When  is  this 
planted?  For  what  purpose?

12.  How  far  apart  should  apple  trees  be  set?  How  may  the  land  be 
utilized  while  the  trees  are  growing?  How  old  must  the  apple  tree  be  to 
come  into  bearing? 

13 . Is  the  practice  now  to  allow  an  apple  tree  to  grow  tall  ? Why  is  an 
apple  tree  with  a short  trunk  better? 

14.  What  does  it  do  to  a tree  to  prune  its  roots?  What  does  it  do  to  a 
tree  to  prune  its  branches  ? 

15.  How  does  it  affect  a tree  to  prune  the  buds  at  the  tips  of  the  twigs  ? 

16.  How  does  it  affect  a tree  to  thin  the  branches?  Describe  how  a 
limb  should  be  pruned  and  how  the  wound  thus  made  should  be  treated. 
Why? 


HOW  AN  APPLE  GROWS 
Teacher's  Story 

An  apple  tree  in  full  blossom  is  a beauti- 
ful sight.  If  we  try  to  analyze  its  beauty  we 
find  that  on  the  tip  of  each  twig  there  is  a 
cluster  of  blossoms,  and  set  around  them,  as 
in  a conventional  bouquet,  are  the  pale,  soft, 
downy  leaves.  These  leaves  and  blossoms 
come  from  the  terminal  winter  buds,  which 
are  protected  during  winter  by  little  scales 
which  are  more  or  less  downy.  With  the 
bursting  of  the  bud,  these  scales  fall  off,  each 
one  leaving  its  mark  crosswise  on  the  twig, 
marking  the  end  of  the  year’s  growth;  these 
little  ridges  close  together  and  in  groups  mark 
the  winters  which  the  twig  has  experienced,  and  thus  reveal  its  age. 

There  is  a difference  in  varieties  of  apples  and  in  the  season  as  to  whether 
the  blossoms  or  the  leaves  push  out  first.  The  white,  downy  leaves  at  first 
have  two  narrow  stipules  at  the  base  of  their  petioles.  They  are  soft, 
whitish  and  fuzzy,  as  are  also  the  flower  stem  and  the  calyx,  which  holds 
fast  in  its  slender,  pointed  lobes  the  globular  flower  bud.  We  speak  of  the 
lobes  of  the  calyx  because  they  are  joined  at  the  base,  and  are  not  entirely 
separate  as  are  sepals.  The  basal  part  of  the  calyx  is  cup-shaped,  and  upon 
its  rim  are  set  the  large,  oval  petals,  each  narrowing  to  a slender  stem  at  its 
base.  The  petals  are  set  between  the  sepals  or  lobes  of  the  calyx,  the  latter 
appearing  as  a beautiful,  pale  green,  five-pointed  star  at  the  bottom  of  the 
flower.  The  petals  are  pink  on  the  outside  and  white  on  the  inside,  and  are 
veined  from  base  to  edge  like  a leaf ; they  are  crumpled  more  than  are  the 
cherry  petals. 

The  many  pale,  greenish  white  stamens  of  different  lengths  and  heights 
stand  up  like  a column  . at  the  center  of  the  flower.  They  are  tipped  with 
pale  yellow  anthers,  and  are  attached  to  the  rim  of  the  calyx-cup.  They 
are  really  attached  in  ten  different  groups  but  this  is  not  easy  to  see. 

The  five  pale  green  styles  are  very  silky  and  downy  and  are  tipped  with 
green  stigmas.  The  pistils  all  unite  at  their  bases  making  a five-lobed, 
compound  ovary.  The  upper  part  of  this  ovary  may  be  seen  above  the 
calyx-cup,  but  the  lower  portion  is  grown  fast  to  it  and  is  hidden  within  it. 
The  calyx-cup  is  what  develops  into  the  pulp  of  the  apple,  and  each  of  these 


Tree  Study 


783 


pistils  becomes  one  of  the  five  cells  in  the  apple  core.  If  one  of  the  stigmas 
does  not  receive  pollen,  its  ovary  will  develop  no  seed;  this  often  makes  the 
apple  lop-sided.  When  the  petals  first  fall,  the  calyx-lobes  are  spread  wide 
apart ; later  they  close  in  toward  the  center,  making  a tube.  T o note  exactly 
the  time  of  this  change  is  important;  since  the  time  of  spraying  for  the 
codling  moth  is  before  the  calyx-lobes  close.  These  lobes  may  be  seen  in 
any  ripe  apple  as  five  little,  wrinkled  scales  at  the  blossom  end ; within  them 
may  be  seen  the  dried  and  wrinkled  stamens,  and  within  the  circle  of 
stamens,  the  sere  and  blackened  styles.

There  may  be  five  or  six,  or  even  more  blossoms  developed  from  one 
winter  bud,  and  there  may  be  as  many  leaves  encircling  them,  forming  a 
bouquet  at  the  tip  of  the  twig.  However,  rarely  more  than  two  of  these 
blossoms  develop  into  fruit,  and  the  fruit  is  much  better  when  only  one 
blossom  of  the  bouquet  produces  an  apple ; if  a tree  bears  too  many  apples 
it  cannot  perfect  them. 

The  blossoms  and  fruit  are  always  at  the  end  of  the  twigs  and  spurs  of 
the  apple  tree,  and  do  not  grow  along  the  sides  of  the  branches  as  do  the 
cherry  and  the  peach.  However,  there  are  many  buds  which  produce  only 
leaves;  and  just  at  the  side  and  below  the  spur,  where  the  apple  is  borne,  a 
bud  is  developed,  which  pushes  on  and  continues  the  growth  of  the  twig, 
and  will  in  turn  be  a spur  and  bear  blossoms  the  following  year.

LESSON  CC 
How  an  Apple  Grows 

Leading  thought — The  purpose  of  the  apple  blossom  is  to  produce  apples 
which  shall  contain  seeds  to  grow  into  more  apple  trees. 

Method — This  lesson  should  begin  with  the  apple  blossoms  in  the  spring 
and  should  continue,  with  occasional  observations,  until  the  apples  are  well 
grown.  If  this  is  not  possible,  the  blossom  may  be  studied,  and  directly 
afterward,  the  apple  may  be  observed  carefully,  noting  its  relation  to  the 
blossom. 

The  Apple  Blossom 

Observations — 1.  How  are  the  apple  buds  protected  in  the  winter?  As 
the  buds  open  what  becomes  of  the  protecting  scales?  Can  you  see  the 
scars  left  by  the  scales  after  they  have  fallen.  How  does  this  help  us  to  tell 
the  age  of  a twig  or  branch? 

2.  As  the  winter  buds  open,  which  appear  first — the  flowers  or  the 
leaves  ? Do  they  both  come  from  the  same  bud  ? Do  all  the  buds  produce 
both  flowers  and  leaves  ? 

3.  Study  the  bud  of  the  apple  blossom.  Describe  its  stem ; its  stipules; 
its  calyx.  What  is  the  shape  and  position  of  the  lobes,  or  sepals,  of  the 
calyx?  Why  do  we  usually  call  them  the  “lobes  of  the  calyx”  instead  of 
sepals? 

4.  Sketch  or  describe  an  open  apple  blossom.  How  many  petals? 
What  is  their  shape  and  arrangement?  Can  you  see  the  calyx-lobes 
between  the  petals  as  you  look  down  into  the  blossom?  What  sort  of  a 
figure  do  they  make  ? Are  the  petals  usually  cup-shaped  ? What  is  their 
color  outside  and  inside  ? Why  do  the  buds  seem  so  pink  and  the  blossoms 
so  white?  , 

5.  How  many  stamens  are  there?  Are  they  all  of  the  same  length? 
What  is  the  color  of  the  filaments  and  anthers?  On  what  are  they  set? 

6.  How  many  pistils  do  you  see?  How  many  stigmas  are  there?  Are 
the  ovaries  united  ? Are  they  attached  to  the  calyx  ? 


Tree  Study 


785 


7.  Describe  the  young  leaves  as  they  appear  around  the  blossoms. 
What  is  their  color?  Have  they  any  stipules?  Why  do  they  make  the 
flowers  look  like  a bouquet  ? 

8.  After  the  petals  fall,  what  of  the  blossom  remains?  What  part 
develops  into  the  apple?  Does  this  part  enclose  the  ovaries  of  the 
pistils  ? How  can  you  tell  in  the  ripe  apple  if  any  stigma  failed  to  receive 
pollen  ? 

9.  What  is  the  position  of  the  calyx-lobes  directly  after  the  petals  fall? 
Do  they  change  later  ? How  does  this  affect  spraying  for  the  codling  moth  ? 

10.  Watch  an  apple  develop;  look  at  it  once  a week  and  tell  what 
parts  of  the  blossom  remain  with  the  apple. 

il  How  many  blossoms  come  from  one  winter  bud?  How  many 
leaves?  Do  the  blossoms  ever  appear  along  the  sides  of  the  branches,  as  in 
the  cherries  ? How  many  blossoms  from  a single  bud  develop  into  apples  ? 

12.  Since  the  apple  is  developed  on  the  tip  of  the  twig  how  does  the 
twig  keep  on  growing? 

1 3 . Compare  the  apple  with  the  pear,  the  plum,  the  cherry  and  the  peach 
in  the  following  particulars;  position  on  the  twigs;  number  of  petals; 
number  and  color  of  stamens;  number  of  pistils;  whether  the  pistils  are 
attached  to  the  calyx-cup  at  the  base. 


THE  APPLE 
Teacher's  Story 

“Man  fell  with  apples  and  with  apples  rose , 

If  this  be  true;  for  we  must  deem  the  mode 
In  which  Sir  Isaac  Newton  could  disclose, 

Through  the  then  unpaved  stars,  the  turnpike  road, 

A thing  to  counterbalance  human  woes.” — Byron. 

PLES  seem  to  have  played  a very  important 
part  in  human  history,  and  from  the  first  had 
much  effect  upon  human  destiny,  judging  from 
the  trouble  that  ensued  both  to  Adam  and  to 
Helen  of  Troy  from  meddling,  even  though 
indirectly,  with  this  much  esteemed  fruit.  It 
is  surely  no  more  than  just  to  humanity — shut 
out  from  the  Garden  of  Eden — that  the  apple 
should  have  led  Sir  Isaac  Newton  to  discover 
the  law  which  holds  us  in  the  universe;  and 
that,  in  these  later  centuries,  apples  have  been 
developed,  so  beautiful  and  so  luscious  as  almost 
to  reconcile  us  to  the  closing  of  the  gates  of  Paradise. 

While  it  is  true  that  no  two  apples  were  ever  exactly  alike,  any  more  than 
any  two  leaves,  yet  their  shapes  are  often  very  characteristic  of  the  varie- 
ties. From  the  big,  round  Baldwin  to  the  cone-shaped  gillyflower,  each  has 
its  own  peculiar  form,  and  also  its  own  colors  and  markings  and  its  own 
texture  and  flavor.  Some  ha^e  tough  skins,  others  bruise  readily  even  with 
careful  handling;  but  to  all  kinds,  the  skin  is  an  armor  against  those  ever- 
present foes,  the  fungus  spores,  myriads  of  which  are  floating  in  the  air

ready  to  enter  the  smallest  breach,  and  by  their  growth  bring  about  decay. 
Even  the  tip  of  a branch  or  twig  swayed  by  the  wind,  may  bruise  an  apple 
and  cause  it  to  rot ; windfalls  are  always  bruised  and  will  not  keep.  Greater 
care  in  packing,  wrapping,  picking  and  storing,  so  as  to  avoid  contact  with 
other  apples,  is  a paying  investment  of  labor  to  the  apple  grower. 

The  cavities  at  the  stem  and  basin-ends  of  the  fruit  are  also  likely  to 
have,  in  the  same  variety,  a likeness  in  their  depth  or  shallowness,  and  thus 
prove  a help  in  identifying  an  apple.  At  the  blossom,  or  basin,  end  of  the 
fruit  may  be  seen  five  scales,  which  are  all  that  remain  of  the  calyx-lobes 
which  enclosed  the  blossom;  and  within  them  are  the  withered  and 
shrunken  stamens  and  styles. 

When  the  fruit  is  cut,  we  see  that  the  inner  parts  differ  as  much  in  the 
different  varieties  as  do  the  outer  parts.  Some  have  large  cores,  others 


e,  carpels;  f,  outer  core-lines,  terminating  at  a point  where  stamens  are  attached;  g, 
fibres  extending  from  stem  to  basin.  Transverse  section  of  apple  showing  the  five  car-

small.  The  carpels,  or  seed-cells,  are  five  in  number,  and  when  the  fruit  is 
cut  across  through  the  center  these  carpels  show  as  a pretty,  five-pointed 
star;  in  them  the  seeds  lie,  all  pointing  toward  the  stem.  Some  apples 
have  both  seeds  and  carpels  smooth  and  shining,  while  in  others  they  are 
tufted  with  a soft,  fuzzy  outgrowth.  The  number  of  seeds  in  each  cell 
varies;  the  usual  number  is  two.  In  case  a carpel  is  empty,  the  apple  is 
often  lopsided,  and  this  signifies  that  the  stigma  of  that  ovary  received  no 
pollen.  The  apple  seed  is  oval,  plump  and  pointed,  with  an  outer  shell,  and 
a delicate  inner  skin  covering  the  white  meat;  this  separates  readily  into 
two  parts,  between  which,  at  the  point,  may  be  seen  the  germ.  The  entire 
core,  with  the  pulp  immediately  surrounding  the  seed  cells,  is  marked  off 
from  the  rest  of  the  pulp  by  the  core-lines,  faint  in  some  varieties  but  dis- 
tinct in  others.  In  our  native  crab-apples  this  separation  is  so  complete 
that,  when  the  fruit  is  ripe,  the  core  may  be  plucked  out  leaving  a globular 
cavity  at  the  center  of  the  apple. 

Extending  from  the  stem  to  the  basin,  through  the  center  of  the  apple, 
is  a bundle  of  fibers,  five  in  number,  each  attached  to  the  inner  edge  of  a 


Tree  Study 


787 


carpel,  or  seed-box.  Other  bundles  of  fibers  pass  through  the  flesh  about 
half  way  between  the  core  and  the  skin.  Delicate  as  they  are,  so  that  no 
one  observes  them  in  eating  the  fruit,  they  show  clearly  as  a second  core- 
line, and  each  terminates  at  a point  in  the  calyx-tube  where  the  stamens 
were  attached — as  can  be  easily  seen  by  dissecting  an  apple.  In  transverse 
section,  these  show  as  ten  faint  dots  placed  opposite  each  outer  point  and 
inner  angle  of  the  star  at  the  center  formed  by  the  carpels.  Sometimes  the 
seed-cells  are  very  close  to  the  stem,  and  the  apple  is  said  to  have  a sessile 
core;  if  at  the  center  of  the  fruit,  it  has  a medium  core;  if  nearest  to  the 
blossom  end,  it  has  a distant  core.  This  position  of  the  core  marks  different 
varieties. 


Basket  of  apples. 


Apples  evefi  of  the  same  variety,  differ  much  in  yield  and  quality 
according  to  the  soil  and  climate  in  which  they  grow.  The  snow  apple 
grows  best  in  the  St.  Lawrence  Valley,  and  New  York  State  is  noted  for  the 
fine  flavor  of  the  Esopus  spitzenburg,  the  northern  spy,  and  the  Newtown 
pippin,  all  of  which  originated  and  grow  best  within  its  boundaries.  Thus, 
each  locality  has  its  favorite  variety. 

Too  often  in  passing  through  the  country,  we  see  neglected  and  unprof- 
itable orchards,  with  soil  untilled,  the  trees  unpruned  and  scale- infested, 
yielding  scanty  fruit,  fit  only  for  the  cider  mill  and  the  vinegar  barrel. 
This  kind  of  orchard  must  pass  away  and  give  place  to  the  new  horticulture.

LESSON  CCI 
The  Apple 

Leading  thought — The  apple  is  a nutritious  fruit,  wholesome  and  easily 
digested.  The  varieties  of  apple  differ  in  shape,  size,  color,  texture  and 
flavor.  A perfect  apple  hasi  no  bruise  upon  it  and  no  worm-holes  in  it.

Handbook  of  Nature-Study 


Method — Typical  blossoms  of  different  varieties  of  apples  should  be 
brought  into  the  schoolroom,  where  the  pupils  may  closely  observe  and  make 
notes  about  their  appearance.  Each  pupil  should  have  one  or  two  apples 
that  may  be  cut  in  vertical  and  transverse  sections,  so  that  the  pulp,  core- 
lines, carpels  and  seeds  may  be  observed.  After  this  lesson  there  should  be 
an  apple  exhibit,  and  the  pupils  should  be  taught  how  to  score  the  apples 
according  to  size,  shape,  color,  flavor  and  texture. 

Observations — i . Sketch  the  shape  of  your  apple.  Is  it  almost  spheri- 
cal, or  flattened,  or  long  and  egg-shaped,  or  with  unequal  tapering  sides? 
How  does  the  shape  of  the  apple  help  in  determining  its  variety? 

2.  What  is  the  color  of  the  skin?  Is  it  varied  by  streaks,  freckles  or 
blotches  ? Has  it  one  blushing  cheek  the  rest  being  of  a different  color  ? 

3 . Is  the  stem  thick  and  fleshy,  or  short  and  knobby,  or  slender  and 
woody  and  long?  Does  each  variety  have  a characteristic  stem? 

4.  Is  the  cavity  or  depression  where  the  stem  grew  narrow  and  deep 
like  a tunnel,  or  shallow  like  a saucer? 

5.  Examine  the  blossom  end,  or  basin.  What  is  its  shape?  Can  you 
find  within  it  the  remnants  of  the  calyx-lobes,  the  stamens  and  the  pistils  of 
the  flower  ? 

6.  What  is  the  texture  of  the  skin  of  the  apple  ? Is  it  thin,  tough,  waxy 
or  oily?  Has  it  a bloom  that  may  be  rubbed  off?  From  what  sort  of 
injury  does  the  skin  protect  the  apple? 

Experiment  1.  Take  three  apples  of  equal  soundness  and  peel  one  of 
them ; place  them  on  a shelf.  Place  one  of  the  unpeeled  apples  against  the 
peeled  one,  and  the  other  a little  distance  from  it.  Does  the  peeled  apple 
begin  to  rot  before  the  other  two  ? Does  the  unpeeled  apple  touching  the 
peeled  one  begin  to  decay  first  at  the  point  of  contact  ? 

Experiment  2.  Take  an  apple  with  a smooth,  unblemished  skin  and 
vaccinate  it  with  some  juice  from  an  apple  that  has  begun  to  decay;  per- 
form the  operation  with  a pin  or  needle,  pricking  first  the  unsound  fruit  and 
then  the  sound  one ; this  may  be  done  in  patterns  around  the  apple  or  with 
the  initials  of  the  operator’s  name.  Where  does  this  apple  begin  to  decay  ? 
What  should  these  two  experiments  teach  us  as  to  the  care  and  storage  of 
fruit  ? 

7 . Cut  an  apple  through  its  center  from  stem  to  blossom  end.  Describe 
the  color,  texture  and  taste  of  the  pulp.  Is  it  coarse  or  fine-grained? 
Crisp  or  smooth?  Juicy,  or  dry  and  mealy?  Sweet  or  sour?  Does  it 
exhale  a fragrance  or  have  a spicy  flavor? 

8.  Is  the  flesh  immediately  surrounding  the  core  separated  from  the 
rest  of  the  pulp  by  a line  more  or  less  distinct?  This  is  called  the  core-line 
and  differs  in  size  and  outline  in  different  varieties.  Can  you  find  any 
connection  between  the  stem  and  blossom  ends  and  the  core  ? Can  you  see 
the  fibrous  threads  which  connect  them? 

9.  Cut  an  apple  transversely  across  the  middle.  In  what  shape  are 
the  seed-cells  arranged  in  the  center?  Do  the  carpels,  or  seed-cells,  vary 
in  shape  in  different  varieties?  Are  they  closed,  or  do  they  all  open  into  a 
common  cavity  ? Can  you  see,  between  the  core-lines  and  the  skin,  faint 
little  dots?  Count,  and  tell  how  they  are  arranged  in  relation  to  the  star 
formed  by  the  core. 

10.  The  stiff,  parchment-like  walls  of  the  seed-cells  are  called  carpels 
How  many  of  these  does  the  apple  contain?  Do  all  apples  have  the  same 
number  of  carpels  ? Are  the  carpels  of  all  varieties  smooth  and  glossy,  or 


Tree  Study

velvety?  How  many  seeds  do  you  find  in  a carpel ? Do  they  lie  with  the 
points  toward  the  stem-end  or  the  blossom-end  of  the  apple?  Where  are 
they  attached  to  the  apple  ? Describe  the  apple  seed — its  outer  and  inner 
coat  and  its  “meat.”  Gan  you  find  the  germ  within  it  which  will,  after  the 
seed  is  planted,  produce  another  apple  tree? 

11.  Is  the  core  at  the  center  of  the  apple,  or  is  it  nearer  to  the  stem-end 
or  to  the  blossom-end  of  the  fruit?  Are  all  apples  alike  in  this  particular? 

1 2 . Describe  fully  all  the  varieties  of  apples  which  you  know,  giving  the 
average  size,  texture  and  color  of  the  skin,  the  shape  of  the  cavities  at  the 
stem  and  blossom  ends,  the  color,  texture  and  flavor  of  the  pulp,  and  the 
position  within  the  apple  of  the  core.

THE  PINE 
Teacher's  Story 

NE  other  of  our  native  trees  is  more  beautiful  than 
the  pine.  In  the  East,  we  have  the  white  pine  with 
its  fine-tasselled  foliage,  growing  often  150  to  200 
feet  in  height  and  reaching  an  age  of  from  two  to 
three  hundred  years.  On  the  Pacific  coast,  the 
splendid  sugar  pine  lifts  its  straight  trunk  from  two 
to  three  hundred  feet  in  height;  and  although  the 
trunk  may  be  from  six  to  ten  feet  in  diameter  yet  it 
looks  slender,  so  tall  is  the  tree.  A sugar  pine  cone 
on  my  desk  measures  2 2 inches  in  length  and  weighs 
almost  one  pound,  although  it  is  dried  and  emptied  of  seed. 

There  is  something  majestic  about  the  pines,  which  even  the  most 
ignorant  feel.  Their  dark  foliage  outlined  against  wintry  skies  appeals  to 
the  imagination,  and  well  it  may,  for  it  represents  an  ancient  tree-costume. 
The  pines  are  among  the  most  ancient  of  trees,  and  were  the  contemporaries 
of  those  plants  which  were  put  to  sleep,  during  the  Devonian  age,  in  the  coal 
beds.  It  is  because  the  pines  and  the  other  evergreens  belong  essentially  to 
earlier  ages,  when  the  climate  was  far  different  than  it  is  to-day,  that  they 
do  not  shed  their  leaves  like  the  more  recent,  deciduous  trees.  They  stand 
among  us,  representatives  of  an  ancient  race,  and  wrap  their  green  foliage 
about  them  as  an  Indian  sachem  does  his  blanket,  in  calm  disregard  of 
modem  fashion  of  attire. 

All  cone-bearing  trees  have  typically  a central  stem  from  which  the 
branches  come  off  in  whorls,  but  so  many  things  have  happened  to  the  old 
pine  trees  that  the  evidence  of  the  whorls  is  not  very  plain;  the  young  trees 
show  this  method  of  growth  clearly,  the  white  pine  having  five  branches  in 
each  whorl.'  Sometimes  pines  are  seen  which  have  two  or  three  stems  near 
the  top ; but  this  is  a story  of  injury  to  the  tree  and  its  later  victory. 

The  very  tip  of  the  central  stem  in  the  evergreens  is  called  “the  leader,* 
because  it  leads  the  growth  of  the  tree  upward;  it  stretches  up  from  the 
center  of  the  whorl  of  last  year’s  young  branches,  and  there  at  its  tip  are  the 
buds  which  produce  this  year’s  branches.  There  is  a little  beetle  which 
seems  possessed  of  evil,  for  it  likes  best  of  all  to  lay  its  rascally  eggs  in  the 
very  tip  of  this  leader;  the  grub,  after  hatching,  feeds  upon  the  bud  and 
bores  down  into  the  shoot,  killing  it.  Then  comes  the  question  of  which 


790 


Handbook  of  Nature-Study 


branch  of  the  tipper 
whorl  shall  be  elected 
to  rise  up  and  take  the 
place  of  the  dead  leader ; 
but  this  is  an  election 
which  we  know  less 
about  than  we  do  of 
those  resulting  from 
our  blanket  ballots. 
Whether  the  tree 
chooses,  or  whether  the 
branches  aspire,  we  may 
not  know;  but  we  do 
know  that  one  branch 
of  this  upper  whorl 
arises  and  continues  the 
growth  of  the  tree. 
Sometimes  there  are 
two  candidates  for  this 
position,  and  they  each 
make  such  a good  strug- 
gle for  the  place  that 
the  tree  grows  on  with 
two  stems  instead  of 
one — and  sometimes 

with  even  three.  This 
evil  insect  injures  the 
leaders  of  other  conifers 
also,  but  these  are  less 
likely  to  allow  two 
competitors  to  take  the 
place  of  the  dead  leader. 

The  lower  branches 
of  many  of  the  pines 
come  off  almost  at  right 
angles  from  the  bole; 
the  foliage  is  borne  above  the  branches,  which  gives  the  pines  a very 
different  appearance  from  that  of  other  trees.  The  foliage  of  most  of 
the  pines  is  dark  green,  looking  almost  black  in  winter ; the  pitch  pine 
has  the  foliage  yellowish  green,  and  the  white  pine,  bluish  green;  each 
species  has  its  own  peculiar  shade.  There  is  great  variation  in  the  color 
and  form  of  the  bark  of  different  species.  The  white  pine  has  nearly 
smooth  bark  on  the  young  trees,  but  on  the  older  ones  it  has  ridges  that  are 
rather  broad,  flat  and  scaly,  separated  by  shallow  sutures,  while  the 
pitch  pine  has  its  bark  in  scales  like  the  covering  of  a giant  alligator. 

The  foliage  of  the  pine  consists  of  pine  needles  set  in  little  bundles  on 
raised  points  which  look  like  little  brackets  along  the  twigs.  When  the  pine 
needles  are  young,  the  bundle  is  enclosed  in  a sheath  making  the  twig  look 
as  if  it  were  covered  with  pin-feathers.  In  many  of  the  species  this  sheath 
remains,  encasing  the  base  of  the  bundle  of  needles ; but  in  the  white  pine  it 
is  shed  early.  The  number  of  leaves  in  the  bundle  helps  to  determine  the 
tree ; the  white  pine  has  five  needles  in  each  bunch,  the  pitch  pine  has  three,

while  the  Austrian  pine  has  two. 

There  is  a great  difference  in  the 
length  and  the  color  of  the  needles 
of  different  species  of  pine.  Those 
of  the  white  pine  are  soft,  delicate 
and  pliable,  and  from  three  to 
four  inches  in  length;  the  needles 

of  the  pitch  pine  are  stiff  and  ^4  pari  0f  a necklace  of  pitch  pine  needles. 
coarse  and  about  the  same  length; 

the  white  pine  needles  are  triangular  in  section,  and  are  set  so  as  to  form  dis- 
tinct tassels,  while  those  of  the  Austrian  pine  simply  clothe  the  ends  of  the 
twigs . The  needles  of  the  pine  act  like  the  strings  of  an  aeolian  harp ; and  the 
wind,  in  passing  through  the  tree,  sets  them  into  vibration,  making  a sighing 
sound  which  seems  to  the  listener  like  the  voice  of  the  tree.  Therefore,  the 
pine  is  the  most  companionable  of  all  our  trees  and,  to  one  who  observes 
them  closely,  each  tree  has  its  own  tones  and  whispers  a different  story. 

The  appearance  of  the  unripe  cone  is  another  convincing  evidence  that 
mathematics  is  the  basis  of  the  beautiful.  -The  pattern  of  the  overlapping

scales  is  intricate  and  yet  regular — to  appreciate  it  one  needs  to  try  to 
sketch  it.  Beneath  each  scale,  when  it  opens  wide,  we  find  nestled  at  its 
base  two  little  seeds  in  twin  boxes;  each  provided  with  a little  wing  so  that 
it  can  sail  off  with  the  wind  to  find  a plaoe  to  grow.  The  shape  of  the  scales 
of  the  cone  is  another  distinguishing  character  of  the  pine,  and  sketching 
the  outside  of  scales  from  several  different  species  of  pine  cones  will  develop 
the  pupils’  powers  of  observation;  the  tip  of  the  scale  may  be  thickened  or 
armed  with  a spine,  and  one  wonders  if  these  spines  are  for  the  purpose  of 
discouraging  the  squirrels  from  stealing  the  green  seeds. 

The  pine  cone  requires  two  years  for  maturing ; the  pistillate  flower  from 
which  it  is  developed  is  a tiny  cone  with  each  scale  spread  wide  and  standing 
upright  to  catch  the  pollen  for  the  tiny  ovule  nestled  within  it.  The  pis- 
tillate flower  of  the  white  pine  grows  near  the  tip  of  the  new  twig,  and  is 
pinkish  in  color.  In  the  Austrian  pine  it  is  the  merest  pink  dot  at  first,  but 
after  a little  shows  itself  to  be  a true  cone  with  pink-purple  scales,  which 
stand  up  very  erect  and  makes  a pretty  object  when  viewed  through  a lens; 
each  scale  is  pink  at  its  three-pointed  tip,  with  pink  wings  just  below,  the 
inner  portions  being  pale  green.  The  cone  is  set  just  beside  the  growing 
tip  of  the  twig,  is  pointed  upward,  and  its  sheath-scales  are  turned  back 
like  chaff  around  its  base. 

In  June  when  the  new  shoots  of  the  pine  twigs  stand  up  like  pale  green 
candles  on  a Christmas  tree,  at  their  bases  may  be  found  the  staminate 
catkins  set  in  radiating  whorls,  making  galaxies  of  golden  stars  against  the 

dark  green  back- 
ground of  foliage.  In 
the  Austrian  pine, 
one  of  these  pollen 
catkins  may  be  an 
inch  or  two  long  and 
a half -inch  in  width; 
each  little  scale  of 
this  cone  is  an  anther 
sac,  filled  to  bursting 
with  yellow  pollen. 
From  these  starry 
pollen  cones  there 
descends  a yellow 
shower  every  time  a 
breeze  passes;  Dr 
the  pine  trees  depend 
upon  the  wind  to  sift 
their  pollen  dust  into 
the  lifted  cups  of  the 
cone  scales,  which 
will  close  upon  the 
treasure  soon.  The 
pollen  grains  of  pine 
are  very  beautiful 
when  seen  through  a 
microscope;  and  it 
seems  almost  incredible  that  the  masses  of  yellow  dust  sifted  in  showers 
from  the  pines  when  in  blossom,  should  be  composed  of  these  beautiful

structures.  When  the  pine  forests  on  the  shores  of  the  Great  Lakes  are  in 
bloom,  the  pollen  covers  the  waves  for  miles  out  from  the  shores. 


White  pine. 

If  we  examine  the  growing  tips  of  the  pine  branches,  we  find  the  leaves 
look  callow  and  pin-feathery.  The  entire  leaf  is  wrapped  in  a smooth, 
shining,  silken  sheath,  at  the  tip  of  which  its  green  point  protrudes.  The 
sheath  is  tough  like  parchment  and  is  cylindrical  because  the  pine  needles 


794 


Handbook  of  Nature-Study 


within  it  are  perfectly  adjusted  one  to  another  in  cylindrical  form.  The 
sheath  is  made  up  of  several  layers,  one  over  the  other,  and  may  be  pulled 
apart.  The  new  leaves  are  borne  on  the  new,  pale  green  wood. 

The  uses  of  pines  are  many.  The  lumber  of  many  of  the  species,  es- 
pecially that  of  the  white  pine,  is  free  from  knots  and  is  used  for  almost 
everything  from  house-building  to  masts  for  ships.  In  the  Southern  States, 
the  long-leafed  pines  are  tapped  for  resin,  which  is  not  the  sap  of  the  tree,  as 
is  generally  supposed.  Pine  sap  is  like  other  sap ; the  resin  is  a product  of 
certain  glands  of  the  tree,  and  is  of  great  use  to  it  in  closing  wounds  and 
thus  keeping  out  the  spores  of  destructive  fungi.  It  is  this  effort  of  the 
tree  to  heal  its  wounds  that  makes  it  pour  resin  into  the  cuts  made  by  the 
turpentine  gatherers.  This  resin  is  taken  to  a distillery,  where  the  turpen- 
tine is  given  off  as  a vapor  and  condensed  in  a coiled  tube  which  is  kept  cold. 
What  is  left  is  known  as  “rosin.”

This  species  stands  upright  normally  and  is  often  over  one  hundred  feet  high;  but  on  the  mountain 
tops,  exposed  to  wind  and  snow,  its  trunk  reclines  on  the  ground  and  its  branches  look  like 
shrubs,  as  shown  in  the  foreground.  Trees  of  the  same  species,  wind-beaten 
but  standing  are  shown  in  the  background.

LESSON  CCII 
The  Pine 

Leading  thought — The  pines  are  among  our  most  ancient  trees.  Their 
foliage  is  evergreen  but  is  shed  gradually.  The  pollen-bearing  and  the 
seed-bearing  flowers  are  separate  on  the  tree.  The  seeds  are  winged  and 
are  developed  in  cones. 


Tree  Study 


795 


Method — At  least  one  pine  tree  should  be  studied  in  the  field.  Any 
species  will  do  but  the  white  pine  is  the  most  interesting.  The  Austrian 
pine  which  is  commonly  planted  in  parks  is  a good  subject.  The  leaves  and 
cones  may  be  studied  in  the  schoolroom,  each  pupil  having  a specimen. 

Observations — i . What  is  the  general  shape  of  the  pine  tree  ? Is  there 
one  central  stem  running  straight  up  through  the  center  of  the  tree  to  the 
top.  Do  you  find  any  trees  where  this  stem  is  divided  into  two  or  three 
near  the  top?  Describe  how  the  pine  tree  grows.  What  is  the  “leader?” 
What  happens  if  the  leader  is  injured?  How  do  the  topmost  branches  of 
the  young  pine  look  ? Do  they  all  come  off  from  the  same  part  of  the  stem  ? 
How  many  are  there  in  a whorl  ? 

2.  What  color  is  the  bark?  Is  it  ridged  or  in  scales? 

3 . Do  the  branches  come  off  the  main  stem  at  right  angles  or  do  they 
lift  up  or  droop  down  ? Where  is  the  foliage  borne  on  the  branches  ? What 
is  the  color  of  the  foliage?  Is  the  pine  foliage  ever  shed  or  does  the  pine 
leaf,  when  it  comes,  stay  on  as  long  as  the  tree  lives  ? 

4.  Study  the  pine  leaves.  Why  are  they  called  needles?  Note  that 
they  grow  several  together  in  what  we  call  a bundle.  How  many  in  one 
bundle?  Is  the  bundle  enclosed  in  a little  sheath  at  the  base?  Are  the 
bundles  grouped  to  make  distinct  tassels  ? Study  one  of  the  needles.  How 
long  is  it?  Is  it  straight  or  curved?  Flexible  or  coarse  and  stiff?  Cut  it 
across  and  examine  it  with  a lens.  What  is  the  outline  in  cross  section? 
Why  does  the  wind  make  a moaning  sound  in  the  pines  ? 

5.  Study  a pine  cone.  Does  it  grow  near  the  tip  of 
the  branch  or  along  the  sides?  Does  it  hang  down  or 
stand  out  stiffly  ? What  is  its  length  ? Sketch  or  describe 
its  general  shape.  Note  that  it  is  made  up  of  short, 
over-lapping  scales.  What  pattern  do  the  scales  make  as 
they  are  set  together?  Describe  or  sketch  one  scale;  has 
it  a thickened  tip  ? Is  there  a spine  at  the  tip  of  the  scale  ? 

6.  Where  in  the  cone  are  the  seeds?  Describe  or 
sketch  a pine  seed.  How  long  is  its  wing?  How  is  it 
carried  and  planted?  When  the  cone  opens,  how  are  the 
seeds  scattered  ? What  creatures  feed  upon  the  pine  seed  ? 

7.  Study  the  pine  when  in  blossom,  which  is  likely  to 
occur  in  June.  This  time  is  easily  determined  because 
the  air  around  the  tree  is  then  filled  with  the  yellow  pollen 
dust.  Study  the  pollen-bearing  flower.  Is  it  conelike  in 
form?  Does  it  produce  a great  deal  of  pollen?  If  you 
have  a microscope,  look  at  the  pollen  through  a high 
objective  and  describe  it.  How  many  of  the  pollen  cat- 
kins are  clustered  together?  On  what  part  of  the  twigs 
are  they  borne?  Where  are  the  pistillate  flowers  which 
are  to  form  the  young  cones?  How  large  are  they  and 
how  do  they  look  at  the  time  the  pollen  is  flying  ? Do  they 
point  upward  or  droop  downward  ? Why  ? Look  beneath 
the  scales  of  a little  cone  with  a lens  and  see  if  you  can  find 
the  flowers.  What  carries  the  pine  pollen  to  the  flowers  in  the  cone? 

8.  Name  all  the  uses  for  pine  lumber  that  you  know.  Write  an 
English  theme  on  how  turpentine  is  produced  from  pines  and  the  effect  of 
this  industry  upon  pine  forests.  Where  does  resin  appear  on  the  pine? 
Of  what  use  is  it  to  the  tree?  Do  you  think  it  is  pine  sap?  What  is  the 
difference  between  resin  and  rosin?

THE  NORWAY  SPRUCE 
Teacher's  Story 

HE  Norway  spruce  is  a native  of  Europe,  and  we 
find  it  in  America  the  most  satisfactory  of  all 
spruces  for  ornamental  planting;  it  lifts  its 
slender  cone  from  almost  every  park  and  private 
estate  in  our  country,  and  is  easily  distinguished 
from  all  other  evergreens  by  the  drooping,  pen- 
dant habit  of  its  twigs,  which  seem  to  hang 
down  from  the  straight,  uplifted  branches.  We 
have  spruces  of  our  own— the  black,  the  white 
and  the  red  spruces ; and  it  will  add  much  to  the 
interest  of  this  lesson  for  the  pupils  to  read  in 
the  tree  and  forestry  books  concerning  these 
American  species.  Chewing  gum  and  spruce  beer  are  the  products  of  the 
black  and  red  spruce  of  our  eastern  forests.  The  Douglas  spruce,  which  is 
a fir  and  not  a spruce,  is  also  commonly  planted  as  an  ornamental  tree,  but

it  is  only  at  its  best  on  the  Pacific  Coast,  where  it  is  one  of  the  most  magni- 
ficent of  trees. 

The  Norway  spruce  tree  is  in  form  a beautiful  cone,  slanting  from  its 
slender  tip  to  the  ground,  on  which  its  lower  drooping  branches  rest;  the 
upper  branches  come  off  at  a narrower  angle  from  the  sturdy  central  stem 
than  do  the  widespreading  lower  branches.  On  the  older  trees,  the  twigs 
hang  like  pendulous  fringes  from  the  branches,  enabling  them  to  shed  the 
snow  more  readily — a peculiarity  which  is  of  much  use  to  the  tree,  because 
it  is  a native  of  the  snowy  northern  countries  of  Europe  and  also  grows 
successfully  in  the  high  altitudes  of  the  Alps  and  other  mountains.  If  we 
stroke  a spruce  branch  toward  the  tip,  the  hand  slides  smoothly  over  it ; but 
brusn  backward  from  the  tip,  and  the  hand  is  pricked  by  hundreds  of  the 
sharp,  bayonet-pointed  leaves;  this  is  another  arrangement  for  letting  the 
snow  slide  off. 

If  we  examine  a twig  of  the  present  year’s  growth,  we  can  see  on  every 
side  of  its  brown  stem  the  pointed  leaves,  each  growing  from  a short  ridge; 
but  the  leaves  on  the  lower  side  stretch  out  sidewise  to  get  the  light,  and 
those  above  lift  up  angularly.  Perhaps  the  twig  of  last  year’s  growth  has 
shed  its  leaves  which  grew  on  the  under  side  and  thus  failed  to  reach  the 
sun.  The  leaf  of  the  spruce  is  curved,  stiff,  four-sided  and  ends  in  a sharp 
point.  It  is  dark  yellowish  above  and  lighter  beneath  and  is  set  stiffly  on 
the  twig.  The  winter  buds  for  next  year’s  growth  may  be 
seen  at  the  tips  of  the  twigs,  covered  with  little,  recurved, 
brown  scales  quite  flowerlike  in  form.  In  the  balsam  fir, 
which  is  often  planted  with  the  Norway  spruce,  these  buds 
are  varnished. 

The  cones  are  borne  on  the  tips  of  the  branches  and 
hang  down.  In  color  they  are  pale,  wood-brown;  they 
are  from  four  to  six  inches  long,  and  are  very  conspicuous. 

They  are  made  up  of  broad  scales  that  .are  thin  toward  the 
notched  tips;  they  are  set  around  the  central  stem  in 
spirals  of  five  rows.  If  we  follow  one  spiral  around  mark- 
ing it  with  a winding  string,  it  will  prove  to  be  the  fifth 
row  above  the  place  where  we  started.  These  manifold 
spirals  can  be  seen  sometimes  by  looking  into  the  tip  end 
of  a cone.  The  cone  has  much  resin  on  it,  and  is  a very 
safe  box  for  seeds;  but  when  it  begins  to  open,  squirrels 
impatiently  tear  it  to  pieces,  harvesting  the  seeds  and 
leaving  a pile  of  cone-scales  beneath  the  tree  to  tell  of  their 
piracy.  _ way  spruce,  show- 

A Norway  spruce  m blossom  is  a beautiful  sight;  the  ing  that  the  spiral 
little,  wine-red  pistillate  cones  are  lifted  upwards  from  the  of  the  scales  is  in 
tips  of  the  twigs,  while  short,  terminal  branches  are  laden  rows  °f  ftve' 
with  the  pollen-bearing  catkins,  which  are  soft  and  cater-  Ph°cr5by.yrus 
pillarish,  growing  on  soft,  white  stems  from  the  base  of 
scales  which  enclosed  and  protected  them  during  the  winter;  these  catkins 
are  filled  with  the  yellow  dust.  The  young  cones  continue  to  stand 
upright  after  the  scales  have  closed  on  the  pollen  which  has  been  sifted 
by  the  wind  to  the  ovules  which  they  guard;  and  for  some  time  they 
remain  most  ornamentally  purplish  red.  Before  the  cone  is  heavy  enough 
to  bend  from  its  own  weight,  it  turns  deliberately  around  and  downward, 
as  if  the  act  were  a wilful  deed,  and  then  changes  its  color  to  green,  ripening 
into  brown  in  the  fall.

Handbook  of  N ature-Study 


The  Norway  spruce  grows  on  the  Alps  abundantly,  and  like  the  youth 
with  the  banner,  “excelsior”  is  not  only  its  motto  but  its  scientific  name, 
{Pi.  ea  excelsa ) . Here  it  grows  to  the  height  of  one  hundred  to  one  hundred 
and  fifty  feet.  Its  wood  is  valuable  and  its  pitch  is  marketed.  In  this 
country,  it  is  used  chiefly  for  ornamental  planting  and  for  wind-breaks. 

LESSON  CCIII 
The  Norway  Spruce 

Leading  thought — The 
Norway  spruce  is  one  of  the 
most  valuable  of  the  trees 
which  have  come  to  America 
from  Europe.  It  grows 
naturally  in  high  places  and 
in  northern  countries  where 
there  is  much  snow ; its 
drooping  twigs  cannot  hold 
a great  burden  of  snow,  and 
thus  it  escapes  being 
crushed. 

Method — This  lesson 
should  begin  in  the  autumn 
when  the  cones  are  ripe. 
The  tree  should  be  observed 
by  all  of  the  pupils,  and  they 
should  bring  in  twigs  and 
cones  for  study  in  the 
schoolroom.  The  lesson 
should  be  taken  up  again 
in  May  when  the  trees  are 
in  blossom. 

Observations — r.  What 
is  the  general  shape  of  the 
tree  ? Do  the  lowter  branches 
come  off  at  the  same  angle 
as  the  upper?  If  un- 
trimmed, what  can  you  see  of  the  trunk  ? Do  the  lower  branches  rest  upon 
the  ground  ? What  advantage  would  this  be  to  the  tree  in  winter  ? Do  the 
twigs  stand  out,  or  droop  from  the  branches  ? Of  what  advantage  is  this  in 
case  of  heavy  snow?  What  is  the  color  of  the  foliage?  Where  did  the 
Norway  spruce  come  from? 

2.  What  is  the  color  of  the  twig?  How  are  the  leaves  set  upon  it? 
Are  there  more  leaves  on  the  upper  than  on  the  under  side  of  the  twigs  of 
this  year’s  growth?  Of  last  year’s  growth?  Brush  your  hand  along  a 
branch  toward  the  tip.  Do  the  leaves  prick?  Brush  from  the  tip  back- 
ward. Is  the  result  the  same  ? Why  is  this  angle  of  the  leaves  to  the  twig 
a benefit  during  snowstorms? 

3.  Take  a single  leaf.  What  is  its  shape?  How  many  sides  has  it? 
Is  it  soft  or  stiff?  Is  it  sharp  at  the  tip?  Describe  the  buds  which  are 
forming  for  next  year’s  growth.  Look  along  the  twigs  and  see  if  you  can 
discover  the  scales  of  the  bud  which  produced  last  year’s  growth?

4.  Where  are  1 he  cones  borne ? How  long  does  it  take  a cone  to  grow? 
Is  it  heavy?  Is  there  resin  on  it ? Note  that  the  scales  are  set  in  a spiral 
around  the  center  of  the  cone.  Wind  a string  around  a cone  following  the 
same  row  of  scales.  How  many  rows  between  those  marked  with  a string? 
Look  into  the  tip  of  a cone  and  see  the  spiral  arrangement.  Sketch  and 
describe  a cone-schle,  paying  special  attention  to  the  shape  of  the  tip.  Try 
to  tear  a cone  apart.  Is  this  easily  done?  Hang  a closed  cone  in  a dry 
place  and  note  what  happens. 

5.  Describe  the  seed,  ics  wings  and  where  it  is  placed  at  the  base  of  the 
scale.  How  many  seeds  under  each  scale?  When  do  the  cones  open  of 

6 themselves  to  scatter  the  seed?  Do  you  observe  squirrels  tearing  these 
i apart  to  get  the  seed  ? 

6.  The  Norway  spruce  blossoms  in  May.  Find  the  little  flower  which 
will  produce  the  cone,  and  describe  it.  What  color  is  it  ? Is  it  upright  or 
hanging  down  ? Do  the  scales  turn  toward  the  tip  or  backward  ? Why  is 
this  ? Where  are  the  pollen-catkins  borne  ? How  many  of  them  arise  from 
the  same  place  on  the  twig?"  Can  you  see  the  little  scales  at  the  base  of 
each  pistillate  catkin  ? What  are  they  ? Are  they  very  full  of  pollen  ? Do 
the  insects  carry  the  pollen  for  the  Norway  spruce,  or  does  the  wind  sift  it 
over  the  pistillate  blossoms  ? After  the  pollen  is  shed,  note  if  the  scales  of 
the  young  cones  close  up.  How  long  before  the  cones  begin  to  droop  ? Do 
you  think  it  is  their  weight  which  causes  them  to  droop  ? 

7.  What  use  do  we  make  of  the  Norway  spruce?  What  is  it  used  for 
in  Europe  ? 


11  All  outward  wisdom  yields  to  that  within, 

Whereof  nor  creed  nor  canon  holds  the  key; 

We  only  feel  that  we  have  ever  been 
And  evermore  shall  be. 

A nd  thus  I know,  by  memories  unfurled 
In  rarer  moods,  and  many  a nameless  sign, 

That  once  in  Time,  and  somewhere  in  the  world , 

I was  a towering  pine. 

Rooted  upon  a cape  that  overhung 

The  entrance  to  a mountain  gorge;  whereon 

The  wintry  shade  of  a peak  was  flung, 

Long  after  rise  of  sun. 

There  did  I clutch  the  granite  with  firm  feet , 

There  shake  my  boughs  above  the  roaring  gulf, 

When  mountain  whirlwinds  through  the  passes  beat, 

A nd  howled  the  mountain  wolf. 

There  did  I louder  sing  than  all  the  floods 
Whirled  in  white  foam  adown  the  precipice, 

A nd  the  sharp  sleet  that  stung  the  naked  woods, 

Answer  with  sullen  hiss. 

I held  the  eagle  till  the  mountain  mist 

Rolled  from  the  azure  paths  he  came  to  soar, 

And  like  a hunter,  on  my  gnarled  wrist 
The  dappled  falcon  bore."

THE  HEMLOCK 
Teacher's  Story 

“ O'er  lonely  lakes  that  wild  and  nameless  lie , 

Black , shaggy,  vast  and  still  as  Barca's  sands 
A hemlock  forest  stands.  Oh  forest  like  a pall! 

Oh  hemlock  of  the  wild , Oh  brother  of  my  soul 
I love  thy  mantle  black,  thy  shaggy  bole. 

Thy  form  grotesque,  thy  spreading  arms  of  steel." 

— Pattee. 

N ITS  prime,  the  hemlock  is  a magnificent  tree. 
It  reaches  the  height  of  from  sixty  to  one  hun- 
dred feet,  is  cone-shaped,  its  fine,  dense  foliage 
and  its  drooping  branches  giving  to  its  appear- 
ance exquisite  delicacy;  and  I have  yet  to  see 
elsewhere  such  graceful  tree-spires  as  are  the 
hemlocks  of  the  Sierras,  albeit  they  have  bend- 
ing tips.  However,  an  old  hemlock  becomes 
very  ragged  and  rugged  in  appearance;  and 
dying,  it  rears  its  wind-broken  branches  against 
the  sky,  a gaunt  figure  of  stark  loneliness. 

The  hemlock  branches  are  seldom  broken  by  snow;  they  droop  to  let 
the  burden  slide  off.  The  bark  is  reddish,  or  sometimes  gray,  and 
is  furrowed  into  wide,  scaly  ridges.  The  foliage  is  a rich  dark  green, 
but  whitish  when  seen  from  below.  The  leaves  of  the  hemlock  are 
really  arranged  in  a spiral,  but  this  is  hard  to  demonstrate.  They 
look  as  though  they  were  arranged  in  double  rows  along  each  side  of  the 
little  twig;  but  they  are  not  in  the  same  plane  and  there  is  usually  a row  of 
short  leaves  on  the  upper  side  of  the  twig.  The  leaf  is  blunt  at  the  tip  and 
has  a little  petiole  of  its  own  which  distinguishes  it  from  the  leaves  of  any 
other  species  of  conifer;  it  is  dark,  glossy  green  above,  pale  green  beneath, 
marked  with  two  white,  lengthwise  lines.  In  June,  the  tip  of  every  twig 
grows  and  puts  forth  new  leaves  which  are  greenish  yellow  in  color,  making 
the  tree  very  beautiful  and  giving  it  the  appearance  of  blossoming.  The 
leaves  are  shed  during  the  third  year.  The  hemlock  cones  are  small  and 
are  borne  on  the  tips  of  the  twigs.  The  seeds  are  borne,  two  beneath  each 
scale,  and  they  have  wings  nearly  as  large  as  the  scale  itself.  Squirrels  are 
so  fond  of  them  that  probably  but  few  have  an  opportunity  to  try  their 
wings.  The  cones  mature  in  one  year,  and  usually  fall  in  the  spring.  The 
hemlock  blossoms  in  May ; the  pistillate  flowers  are  very  difficult  to  observe 
as  they  are  tiny  and  greenish  and  are  placed  at  the  tip  of  the  twig.  The 
pollen-bearing  flowers  are  little,  yellowish  balls  on  delicate,  short  stems, 
borne  along  the  sides  of  the  twig. 

Hemlock  bark  is  rich  in  tannin  and  is  used  in  great  quantities  for  the 
tanning  of  leather.  The  timber,  which  is  coarse-grained,  is  stiff  and  is  used 
in  framing  buildings  and  for  railroad  ties;  nails  and  spikes  driven  into  it 
cling  with  great  tenacity  and  the  wood  does  not  split  in  nailing.  Oil  dis- 
tilled from  the  leaves  of  hemlock  is  used  as  an  antiseptic. 

The  dense  foliage  of  the  hemlock  offers  a shelter  to  birds  of  all  kinds  in 
winter;  even  the  partridges  roost  in  the  young  trees.  These  young  tree 
often  have  branches  drooping  to  the  ground,  making  an  evergreen  tent

Handbook  of  Nature-Study 


which  forms  a winter  harbor  for  mice  and  other  beasties.  The  seed-eating 
birds  which  remain  with  us  during  the  winter,  feed  upon  the  seeds;  and  as 
the  cones  grow  on  the  tips  of  the  delicate  twigs,  the  red  squirrels  display 
their  utmost  powers  as  acrobats  when  gathering  this,  their  favorite  food. 


LESSON  CCIV 
The  Hemlock 

Leading  thought — This  is  one  of  the  most  common  and  useful  and  beauti- 
ful of  our  evergreen  trees.  Its  fine  foliage  makes  it  an  efficient  winter  shel- 
ter for  birds 

Method — Ask  the  children  the  questions  and  request  them  to  make  notes 
on  the  hemlock  trees  of  the  neighborhood.  The  study  of  the  leaves  and  the 
cones  may  be  made  in  the  schoolroom. 

Observations — i.  Where  does  the  hemlock  tree  grow  in  your  neighbor- 
hood? What  is  the  general, shape  of  the  tree?  What  sort  of  bark  has  it ? 
How  tall  does  it  grow  ? How  are  its  branches  arranged  to  shed  the  snow  ? 

2.  What  is  the  color  of  the  foliage?  How  are  the  leaves  arranged  on 
the  twigs  ? Are  all  the  leaves  of  about  the  same  size  ? What  is  the  position 
of  the  smaller  leaves  ? 

3 . Break  off  a leaf  and  describe  its  shape ; its  petiole.  Does  the  leaf  of 
any  other  evergreen  have  a petiole  ? What  is  the  color  and  marking  of  the 
hemlock  leaf  above?  Below?  At  what  time  of  year  are  the  new  leaves 
developed  ? How  does  the  hemlock  tree  look  at  this  time  ? Does  the  hem- 
lock ever  shed  its  leaves?

4.  Are  the  hemlock  cones  borne  on  the  tip  of  the  twigs  or  along  the 
side  ? How  long  does  it  take  a cone  to  mature  ? When  does  it  fall  ? How 
many  scales  has  it  ? Where  are  the  seeds  borne  ? How  many  seeds  beneath 
each  scale?  Describe  and  sketch  a hemlock  seed.  How  are  the  seeds 
scattered  ? Study  the  tree  in  May,  and  see  if  you  can  find  the  blossom  ? 

5.  Make  drawings  of  the  following:  The  hemlock  twig,  showing  the 

arrangement  of  the  leaves ; single  leaf,  enlarged;  cone;  cone  scale;  seed. 

6.  What  creatures  feed  upon  the  hemlock  seed?  What  birds  find  pro- 
tection in  the  hemlock  foliage  in  winter  ? 

7 . For  what  purposes  is  hemlock  bark  used  ? What  is  the  timber  good 
for?  Is  a nail  easily  pulled  out  from  a hemlock  board? 


THE  DOGWOOD 
Teacher's  Story 

Through  cloud  rifts  the  sunlight  is  streaming  in  floods  to  far  depths  of  the  wood, 
Retouching  the  velvet-leafed  dogwood  to  crimson  as  vital  as  blood. 


HERE  is  no  prettier  story  among  the  flowers  than 
that  of  the  bracts  of  the  dogwood,  and  it  is  a 
subject  for  investigation  which  any  child  can 
work  out  for  himself.  I shall  never  forget  the 
thrill  of  triumph  I experienced  when  I dis- 
covered for  myself  the  cause  of  the  mysterious 
dark  notch  at  the  tip  of  each  great  white  bract, 
which  I had  for  years  idly  noticed.  One  day 
my  curiosity  mastered  my  inertia,  and  I hunted 
a tree  over  for  a flower  bud,  for  it  was  rather  late  in  the  season;  finally  I 
was  rewarded  by  finding  the  bracts  in  all  stages  of  development. 

The  flowering  dogwood  forms  its  buds  during  the  summer,  and  of  course 
they  must  have  winter  protection;  therefore,  they  are  wrapped  in  four, 
close-clasping,  purplish  brown  scales,  one  pair  inside  and  one  pair  outside, 
both  thick  and  well  fitted  to  protect  the  bunch  of  tiny  flower  buds  at  their 
center.  But  when  spring  comes,  these  motherly  bud-scales  change  their 
duties,  and  by  rapid  growth  become  four  beautiful  white  or  pinkish  bracts 
calling  aloud  to  all  the  insect  world  that  here  at  their  hearts  is  something 
sweet. 1 For  months  they  brood  the  flowers  and  then  display  them  to  an 
admiring  world.  The  artistic  eye  loves  the  little  notch  at  the  tip  of  the 
bracts,  even  before  it  has  read  in  it  the  story  of  winter  protection,  of  which 
it  is  an  evidence. 


The  study  of  the  flowers  at  the  center  is  more  interesting  if  aided  by  a 
lens.  Within  each  blossom  can  be  seen  its  tube,  set  in  the  four-lobed  calyx. 
It  has  four  slender  petals  curled  back,  its  four  chubby, 
greenish  yellow  anthers  set  on  filaments  wh'ch  lift  them 
up  between  the  petals ; and  at  the  center  of  all  is  the  tiny 
green  pistil.  There  may  be  twenty,  more  or  less,  of 
these  perfect  flowers  in  this  tiny,  greenish  yellow  bunch  at 
the  center  of  the  four  great,  flaring  bracts.  These  flowers 
do  not  open  simultaneously,  and  the  yellow  buds  and  open  Bhsscl%Znd  bud  o) 
flowers  are  mingled  together  m the  rosette.  The  calyx  dogwood,  enlarged.

shows  better  on  the  bud  than  on  the  open  flower.  It  might  be  well  to 
explain  to  the  pupils  that  a bract  is  simply  a leaf  in  some  other  business 
than  that  ordinarily  performed  by  leaves. 

The  twigs  have  a beautiful,  smooth  bark,  purplish  brown  above 
and  greenish  below.  The  flowers  grow  at  the  tips  of  the  twigs;  and 
the  young  leaves  are  just  below  the  flowers  and  also  at  the  tips  of  the 
twigs.  These  twigs  are  spread  and  bent  in  a peculiar  way,  so  that  each 
white  flower-head  may  be  seen  by  the  admiring  world  and  not  be  hidden 
behind  any  of  its  neighbors.  This  habit  makes  this  tree  a favorite  for  plant- 
ing, since  it  forms  a mass  of  white  bloom. 


The  flowers  of  dogwood.

The  dogwood  banners  unfurl  before  the  flowers  at  their  hearts  open,  and 
they  remain  after  the  last  flower  has  received  within  itself  the  gracious,  vital 
pollen  which  will  enable  it  to  mature  into  a beautiful  berry.  This  long 
period  of  bloom  is  another  quality  which  adds  to  the  value  of  the  dogwood 
as  an  ornamental  tree.  At  the  time  the  bracts  fall,  the  curly  petals  also  fall 
out  leaving  the  little  calyx-tubes  standing  with  style  and  stigma  projecting 
from  their  centers,  making  them  look  like  a bunch  of  liliputian  churns  with 
dashers.  In  autumn,  the' foliage  turns  to  a rich,  purplish  crimson — a most 
satisfying  color. 

During  the  winter,  the  flowering  dogwood,  which  renders  our  forests  so 
beautiful  in  early  spring,  may  be  readily  recognized  by  its  bark,  which  is 
broken  up  into  small  scales  and  mottled  like  the  skin  of  a serpent ; and  on 
the  tips  of  its  branches  are  the  beautiful  clusters  of  red  berries,  or  speaking 
more  exactly,  drupes.  This  fruit  is  oval,  with  a brilliant,  shining,  red, 
pulpy  covering  which  must  be  attractive  to  birds.  At  its  tip  it  has  a little 
purple  crown,  in  the  center  of  which  may  be  seen  the  remnant  of  the  style,

but  this  attractive  outside  covers  a seed  with  a very  thick,  hard  shell, 
which  is  quite  indigestible  and  fully  able  to  protect,  even  from  the  attack  of 
the  digestive  juices  of  the  bird’s  stomach,  the  tender  white  kernel  within  it, 
which  includes  the  stored  food  and  the  embryo.  There  are  in  the  North 
two  other  common  species  of  dogwood  which  have  dark  blue  fruit. 

LESSON  CCV 
The  Dogwood 

Leading  thought — The  petals  are  not  the  only  means  of  attracting  insects 
to  the  flowers.  Sometimes  other  parts  of  the  plant  are  made  into  banners 
to  show  insects  where  the  nectar  is  to  be  found. 

Method — Bring  in  a branch  of  the  dogwood  when  it  is  in  flower.  The 
branch  should  have  upon  it  some  flowers  that  are  unopened.  Study  the 
flower  first,  and  ask  the 
pupils  to  discover  for 
themselves  why  the 
great  white  bracts  have 
a notch  in  the  tip.  A 
lens  is  a great  help  to 
the  interest  in  studying 
these  tiny  flowers. 

Observations — i. 

What  is  there  at  the 
center  of  the  dogwood 
flower?  How  do  the 
parts  at  the  center  look  ? 

Are  they  of  the  same 
shape?  Are  some 
opened  and  others  not  ? 

Take  a penknife  and 
cut  out  one  that  is 
opened  and  describe  it. 

Can  you  see  how  many 
petals  this  tiny  flowei 
has  ? Describe  its 
calyx.  How  many  sta- 
mens has  it?  Can  you 
see  the  pistil  ? If  a flower  has  a calyx  and  stamens  and  a pistil,  has  it  not  all 
that  a flower  needs? 

2.  How  many  of  these  flowers  are  there  at  the  center  of  the  dogwood 
“blossom?”  What  color  are  they?  Would  they  show  off  much  if  it  were 
not  for  the  great  white  banners  around  them  ? Do  we  not  think  of  these 
great  white  bracts  as  the  dogwood  flower  ? 

3 . Study  one  of  these  banners.  What  is  its  shape  ? Are  the  four  white 
bracts  the  same  shape  and  size?  Make  a sketch  of  these  four  bracts  with 
the  bunch  of  flowers  at  the  center.  What  is  there  peculiar  about  each  one 
of  these  white  bracts.  Why  should  this  notch  be  there?  Find  one  of  the 
flower-heads  which  is  not  yet  opened  and  watch  it  develop,  and  then  write 
a little  story  of  the  work  done  in  the  winter  for  the  flowers  by  these  bracts 
and  the  different  work  done  by  them  in  the  spring,  all  for  the  sake  of  the 
precious  blossoms.

4.  Sketch  the  bracts  from  below.  Is  one  pair  wider  than  the  other? 
Is  the  wider  pair  inside  or  outside?  Why  is  this  so? 

5.  Where  are  the  flowers  of  the  dogwood  borne?  How  are  the  twigs 
arranged  so  as  to  unfurl  all  the  banners  and  not  hide  one  behind  another,  so 
that  the  whole  tree  is  a mass  of  white  ? 

6 . While  studying  the  flowers,  study  where  the  young  leaves  come  from. 
Can  you  still  see  the  scales  which  protected  the  leaf  buds  ? 

7.  What  kind  of  fruit  develops  from  the  dogwood  blossoms?  What 
colors  are  its  leaves  in  autumn? 


THE  VELVET,  OR  STAGHORN,  SUMAC 
Teacher's  Story 

The  sumacs  with  flame  leaves  at  half-mast , like  wildfire  spread  over  the  glade; 

A hove  them,  the  crows  on  frayed  pinions  move  northward  in  ragged  parade. 

HE  sumacs,  in  early  autumn,  form  a “firing  line”  along 
the  borders  of  woodlands  and  fences,  before  any  other 
plant  but  the  Virginia  creeper  has  thought  of  taking 
on  brighter  colors.  No  other  leaves  can  emulate  the 
burning  scarlet  of  their  hues.  The  sumacs  are  a glory 
to  our  hills;  and  sometime,  when  Americans  have 
time  to  cultivate  a true  artistic  sense,  these  shrubs 
will  play  an  important  part  in  landscape  gardening. 
They  are  beautiful  in  summer,  when  each  crimson 
“bob”  (a  homely  New  England  name  for  the  fruit 
panicle)  is  set  at  the  center  of  the  bouquet  of  spread- 
ing, fernlike  leaves.  In  winter  nakedness  they  are 
most  picturesque,  with  their  broadly  branching  twigs  bearing  aloft  the  w'ne- 
colored  pompons  against  the  background  of  snow,  and  calling  to  the  winter 
birds  to  come  and  partake  of  the  pleasantly  acid  drupes.  In  spring,  they 
put  out  their  soft  leaves  in  exquisite  shades  of  pale  pinkish  green,  and  when 
in  blossom  their  staminate  panicles  of  greenish  white  cover  them  with  loose 
pryamids  of  delicate  bloom. 

Well  may  it  be  called  velvet  sumac,  for  this  year’s  growth  of  wood  and 
the  leaf  stems  are  covered  with  fine  hairs,  pinkish  at  first,  but  soon  white; 
if  we  slip  our  fingers  down  a branch,  we  can  tell  even  without  looking  where 
last  year’s  growth  began  and  ended,  because  of  the  velvety  feel.  Th.3  name 
staghorn  sumac  is  just  as  fitting,  for  its  upper  branches  spread  widely  like  a 
stag’s  horns  and,  like  them,  the  new  growth  is  covered  with  velvet. 

The  leaves  are  borne  on  the  new  wood,  and  therefore  at  the  ends  of 
branches;  they  are  alternate;  the  petiole  broadens  where  it  clasps  the 
branch,  making  a perfect  nursery  for  the  little  next-year’s  bud,  which  is 
nestled  below  it.  The  leaves  are  compound  and  the  number  of  leaflets 
varies  from  eleven  to  thirty-one.  Each  leaflet  is  set  close  to  the  midrib, 
with  a base  that  is  not  symmetrical ; the  leaflets  have  their  edges  toothed, 
and  are  long  and  narrow ; they  do  not  spread  out  on  either  side  the  midrib 
like  a fern,  but  naturally  droop  somewhat,  and  thus  conceal  their  under- 
sides, which  are  much  lighter  in  color.  The  leaflets  are  not  always  set 
exactly  opposite;  the  basal  ones  are  bent  back  toward  the  main  stem,  mak- 


Tree  Study

ing  a fold  in  the  base  of  each.  The  end  leaflets  are  not  always  three,  sym- 
metrically set,  but  sometimes  are  two  and  sometimes  one,  with  two  basal 
lobes. 

The  wine-colored  “bob”  is  cone-shaped,  but  with  a bunchy  surface. 
Remove  all  the  seeds  from  it  and  note  its  framework  of  tiny  branches,  and 
again  pay  admiring  tribute  to  nature’s  way  of  doing  up  compact  packages. 
Each  seed  is  a drupe,  as  is  also  the  cherry.  A drupe  is  merely  a seed  within 
a fleshy  layer,  all  being  enclosed  in  a firmer  outside  covering;  here,  the  out- 
side case  is  covered  with  dark  red  fuzz,  a clothing  of  furs  for  winter,  the  fur 
standing  out  in  all  directions.  The  fleshy  part  around  the  seed  has  a 
pleasantly  acid  taste,  and  one  of  my  childhood  diversions  was  to  share  these 
fruits  in  winter  with  the  birds.  I probably  inadvertently  ate  also  many  a 
little  six-footed  brother  hidden  away  for  winter  safe-keeping,  for  every 
sumac  panicle  is  a crowded  insect-tenement. 

It  is  only  in  its' winter  aspect  that  we  can  see  the  peculiar  way  of  the 
sumac’s  branching,  which  is  in  picturesque  zigzags,  ending  with  coarse, 
wide-spreading  twigs.  As  each  terminal  twig  was  a stem  for  the  bouquet  of 
blossom  and  fruit  set-  about  with  graceful  leaves,  it  needed  room  and  this  is 
reason  enough  for  the  coarse  branching.  The  wood  of  the  sumac  has  a pith, 
and  is  coarse  in  texture. 

During  late  May  the  new  growth  starts  near  the  end  of  last  year’s  twig; 
the  buds  are  yellowish  and  show  off  against  the  dark  gray  twigs.  From  the 
center  of  these  buds  comes  the  fuzzy  new  growth,  which  is  usually  reddish 
purple;  the  tiny  leaves  are  folded,  each  leaflet  creased  at  its  midrib  and

folded  tightly  against  itself;  as  the  leaves  unfold,  they  are  olive-green 
tinted  with  red,  and  look  like  tassels  coming  out  around  the  old  dark  red 
“bob.”  When  the  sumacs  are  in  blossom,  we  see  in  every  group  of  them, 
two  kinds;  one  with  pyramids  of  white  flowers,  and  the  other  with  pinkish 
callow  bobs.  The  structure  of  these  two  different  flower-clusters  is  really 
the  same,  except  that  the  white  ones  are  looser  and  more  widely  spread. 
Each  flower  of  the  white  panicle  is  staminate,  and  has  five  greenish,  some- 
what hairy  sepals  and  five  yellowish  white  petals,  at  the  center  of  which  are 
five  large  anthers.  A flower  from  the  bob  is  quite  different ; it  has  the  five 
hairy  sepals  alternating  with  five  narrow,  yellowish  white  petals,  both 
clasping  the  globular  base,  or  ovary,  which  is  now  quite  covered  with  pinkish 
plush,  and  bears  at  its  tip  the  three  styles  flaring  into  stigmas. 

The  velvet  sumac  is  larger  than  the  smooth  species 
{Rhus  glabra),  and  is  easily  distinguished  from  it,  since 
the  new  wood  of  the  latter  is  smooth  and  covered  with 
bloom  but  is  not  at  all  velvety.  The  poison  sumac, 
which  is  very  dangerous  to  many  people  when  handled, 
is  a swamp  species  and  its  fruit  is  a loose,  drooping  panicle  of 
whitish  berries,  very  much  like  that  of  poison  ivy;  therefore, 
any  sumac  that  has  the  red  bob  is  not  dangerous.  The  poison 
species  has  the  edges  of  its  leaflets  entire  and  each  leaflet  has  a 
distinct  petiole  of  its  own  where  it  joins  the  midrib. 

There  is  much  tannin  in  sumac  and  it  is  used  extensively  to 
tan  leather.  The  bobs  are  used  for  coloring  a certain  shade  of 
brown.  The  famous  Japanese  lacquer  is  made  from  the  juice  of 
a species  of  sumac. 

LESSON  CCVI 

The  Velvet,  or  Staghorn,  Sumac 
Leading  thought — The  sumac  is  a beautiful  shrub  in  summer  because  of 
its  fern-like  leaves;  it  is  picturesque  in  winter,  and  its  colors  in  autumn  are 
most  brilliant.  Its  dark  red  fruit  clusters  remain  upon  it  during  the  entire 
winter.  In  June  it  shows  two  kinds  of  blossoms  on  different  shrubs,  one  is 
whitish  and  bears  the  pollen,  the  other  is  reddish  and  is  a pistillate  flower, 
later  developing  into  the  seed  on  the  “bob,”  or  fruit  cluster. 

Method — Begin  this  study  in  October  when  the  beautiful  autumn  color 
of  the  leaves  attracts  the  eye.  Observations  to  be  made  in  the  field  should 
be  outlined  and  should  be  answered  in  the  field  note-books.  The  study  of 
the  fruit  and  leaf  may  be  made  in  the  schoolroom,  and  an  interest  should  be 
developed  which  will  lead  to  the  study  of  the  interesting  flowers  the  follow- 
ing spring.  The  sumacs  in  autumn  make  a beautiful  subject  for  water- 
color  sketches,  and  their  peculiar  method  of  branching  with  their  dark  red 
seed  clusters  or  bobs,  make  them  excellent  subjects  for  winter  sketching. 

Observations — i . Why  is  this  called  the  velvet  sumac  ? Why  is  it  called 
the  staghorn  sumac?  Look  at  the  stems  with  a lens  and  describe  the 
velvet.  Can  you  tell  this  year’s  wood  by  the  velvet?  Is  there  any  velvet 
on  last  year’s  wood?  Is  there  any  on  the  wood  below?  What  is  there 
peculiar  in  the  appearance  of  last  year’s  wood?  What  are  the  colors  of  the 
hairs  that  make  the  velvet  on  this  year’s  growth?  On  last  year’s  growth? 
What  is  the  color  of  this  year’s  growth  under  the  velvet?  Where  are  the 
leaves  borne?

2 . Look  at  the  leaves.  How  many  come  off  the  stem  between  two,  one 
of  which  is  above  the  other?  Is  the  midrib  velvety?  What  is  its  color  at 
base  and  at  tip ? What  is  the  shape  of  the  petiole  where  it  joins  the  stem? 
Remove  the  leaf.  What  do  you  find  hidden  and  protected  by  its  broad 
base? 

3.  How  many  leaflets  are  there  on  the  longest  leaf  which  you  can  find? 
How  many  on  the  shortest  ? Do  the  leaflets  have  little  petioles,  or  are  they 
set  close  to  the  midrib  ? How  does  the  basal  pair  differ  from  the  others  ? 
Are  the  leaflets  the  same  color  above  as  below?  Are  the  pairs  set  exactly 
opposite  each  other  ? Look  at  the  three  leaflets  at  the  tips  of  several  leaves 
and  see  if  they  are  all  regular  in  form.  Draw  a leaflet  showing  its  base,  its 
veins  and  its  margin.  Draw  an  entire  leaf,  and  color  it  as  exactly  as 
possible. 

4.  Study  the  fruit.  Pick  one  of  the  bobs  and  note  its  general  shape. 
Is  it  smooth  or  bunchy  ? Sketch  it.  Remove  one  of  the  little  bunches  and 
find  out  why  it  is  of  that  shape.  Remove  all  of  the  seeds  from  one  of  last 
year’s  bobs  and  see  how  the  fruit  is  borne.  Sketch  a part  of  such  a bare 
stem. 

5.  Take  a single  seed;  look  at  it  through  a lens  and  describe  it.  What 
are  the  colors?  Cut  or  pare  away  the  flesh,  and  describe  the  seed.  What 
birds  live  on  the  sumac  seeds  in  winter?  How  many  kinds  of  insects  can 
you  find  wintering  in  the  bob  ? Find  a seed  free  from  insects  and  taste  it. 

Winter  study  of  the  Sumac — 6.  Study  the  sumac  after  the  leaves  have 
fallen  and  sketch  it.  What  is  there  peculiar  in  its  branching?  Of  what 
use  to  the  plant  is  its  method  of  branching  ? Break  a branch  and  look  at  the 
end.  Is  there  a pith?  What  color  is  the  wood  and  pith ? 

May  or  June  Study  of  the  Sumac — 7.  Where  on  the  branch  does  the 
new  growth  start  ? How  are  the  tiny  leaves  folded  ? Look  over  a group  of 
sumacs  and  see  if  their  blossoms  all  look  alike.  Are  the  different  kinds  of 
blossoms  found  on  the  same  tree  or  on  different  trees?  Take  one  of  the 
white  pyramidal  blossom  clusters;  look  at  one  of  these  flowers  with  a lens 
and  describe  its  sepals  and  petals.  How  many  anthers  has  it  and  where  are 
they?  This  is  a pollen-bearing  flower  and  has  no  pistil.  How  are  its  tiny 
staminate  flowers  arranged  on  the  stem  to  give  the  beautiful  pyramid 
shape?  This  kind  of  flower  cluster  is  called  a panicle. 

8.  Take  one  of  the  green  bobs  and  see  if  it  is  made  up  of  little  round 
flowers.  Through  a lens  study  one  of  these.  How  many  sepals?  How 
many  petals?  Describe  the  middle  of  the  flower  around  which  the  petals 
and  sepals  clasp.  Is  this  the  ovary,  or  seed  box?  Can  you  see  the  stigmas 
protruding  beyond  it  ? What  insects  visit  these  flowers  ? 

9.  How  can  you  tell  the  velvet  or  staghorn  sumac  from  the  smooth 
sumac?  How  can  you  tell  both  of  these  from  the  poison  sumac? 

10.  To  what  uses  are  the  sumacs  put? 


“I  see  the  partridges  feed  quite  extensively  upon  the  sumach  berries,  at  my  old  house. 
They  come  to  them  after  every  snow,  making  fresh  tracks,  and  have  now  stripped  many 
bushes  quite  bare."

THE  WITCH-HAZEL 
Teacher's  Story 

In  the  dusky,  somber  woodland,  thwarting  vistas  dull  and  cold, 
Thrown  in  vivid  constellations,  gleam  the  hazel  stars  of  gold, 
Gracious  gift  of  wealth  untold. 

Hazel  blossoms  brightly  gl owing  through  the  forests  dark  and  drear, 
Work  sweet  miracles,  bestowing  gladness  on  the  dying  year, 

Joy  of  life  in  woods  grown  sere. 


ITCH-HAZEL  is  not  only  a most  interesting 
shrub  in  itself,  but  it  has  connected  with  it  many 
legends.  From  its  forked  twigs  were  made  the 
divining  rods  by  which  hidden  springs  of  water 
or  mines  of  precious  metals  were  found,  as  it  was 
firmly  believed  that  the  twig  would  turn  in  the 
hand  when  the  one  who  held  it  passed  over  the 
spring  or  mine.  At  the  present  day,  its  fresh 
leaves  and  twigs  are  used  in  large  quantities  for 
the  distilling  of  the  healing  extract  so  much  in 
demand  as  a remedy  for  cuts  and  bruises  and 
for  chapped  or  sunburned  skins.  It  is  said  that  the  Oneida  Indians  first 
taught  the  white  people  concerning  its  medicinal  qualities. 

The  witch-hazel  is  a large  shrub,  usually  from  six  to  twelve  feet  high, 
although  under  very  advantageous  circumstances  it  has  been  known  to 
take  a tree-like  form  and  attain  a height  of  more  than  twenty  feet.  Its 
bark  is  very  dark  grayish  brown, 
smooth,  specked  with  little  dots, 
which  are  the  lenticels,  or  breathing- 
pores.  If  the  season’s  growth  has 
been  rapid,  the  new  twigs  are  lighter 
in  color,  but  when  stunted  by  drouth 
or  poor  soil,  the  new  growth  has  a tint 
similar  to  the  old.  The  wood  is 
white,  very  tough  and  fibrous,  with 
a pith  or  heart-wood  of  softer  sub- 
stance and  yellow  in  color.  The 
leaves  are  alternate,  and  the  leaf  buds 
appear  at  the  tips  of  the  season’s 
twigs,  while  the  blossoms  grow  at  the 
axils  of  the  leaves. 

The  witch-hazel  leaf  is  nearly  as 
broad  as  it  is  long,  bluntly  pointed  at 
its  tip,  with  a stem  generally  less  than 
one-half  inch  in  length.  The  sides 
are  unequal  in  size  and  shape,  and  the 
edges  are  roughly  scalloped.  The 
veins  are  straight,  are  depressed  on 
the  upper  side  but  very  prominent 
beneath,  and  they  are  lighter  in  color 

than  the  rest  of  the  leaf.  Witch-  Wiich-hazeL

hazel  leaves  are  likely  to  be  apartment  houses  for  insects,  especially  the 
insects  that  make  galls.  Of  these  there  are  many  species,  each  making  a 
different  shaped  gall.  One  of  the  most  common  is  a gall,  shaped  like  a little 
horn  or  spur  on  the  upper  side  of  the  leaf  and  having  a tiny  door  opening  on 
the  under  side  of  the  leaf.  If  one  of  these  snug  little  homes  is  torn  open,  it 
will  be  found  occupied  by  a community  of  little  aphids,  or  plant-lice. 

The  witch-hazel  blossoms  appear  at  the  axil  of  a leaf  or  immediately 
above  the  scar  from  which  a leaf  has  fallen,  the  season  of  bloom  being  so  late 
that  often  the  bush  is  bare  of  leaves  and  is  clothed  only  with  the  yellow, 
fringe-like  flowers.  Usually  the  flowers  are  in  c usters  of  three,  but  occa- 
sionally four  or  five  can  be  found  on  the  same  very  short  sfem.  The  calyx 
is  four-lobed,  the  petals  are  four  in  number,  shaped  like  tiny,  yellow  ribbons, 
about  one-half  inch  long  and 
not  much  wider  than  a coarse 
thread.  In  the  bud,  these 
petals  are  rolled  inward  in  a 
close  spiral,  like  a watch- 
spring,  and  are  coiled- so  tightly 
that  each  bud  is  a solid  little 
ball  no  larger  than  a bird-shot. 

There  are  four  stamens  lying 
between  the  petals,  and  be- 
tween each  two  of  these 
stamens  is  a little  scale  just 
opposite  the  petal.  The 
anthers  are  most  interesting. 

Each  has  two  little  doors 
which  fly  open,  as  if  by  magic 
springs,  and  throw  out  the 
pollen  which  clings  to  them. 

The  pistil  has  two  stigmas, 
which  are  joined  above  the 
two-celled  seed-box,  or  ovary. 

The  blossoms  sometimes  open 
in  late  September,  but  the 
greater  number  appear  in 
October  and  November.  They  are  more  beautiful  in  November  after 
the  leaves  have  fallen,  since  these  yellow,  starry  flowers  seem  to  bring 
light  and  warmth  into  the  landscape.  After  the  petals  fall,  the  calyx 
forms  a beautiful  little  urn,  holding  the  growing  fruit. 

The  nuts  seem  to  require  a sharp  frost  to  separate  the  closely  joined 
parts ; it  requires  a complete  year  to  mature  them.  One  of  these  nuts  is 
about  half  an  inch  long  and  is  covered  with  a velvety  green  outer  husk,  until 
the  frost  turns  it  brown;  cutting  through  it  discloses  a yellowish  white 
inner  shell,  which  is  as  hard  as  bone ; within  this  are  the  two  brown  seeds 
each  ornamented  with  a white  dot ; note  particularly  that  these  seeds  lie  in 
close-fitting  cells.  The  fruit,  if  looked  at  when  the  husk  is  opening,  bears

Frosty  nights  will  open  the  husks,  and  the  dry  warmth  of  sunny  days  or  of

records  one  actual  measurement  of  forty-five  feet.  The  children  should 
note  that  the  surface  of  the  seeds  is  very  polished  and  smooth,  and  the  way 
they  are  discharged  may  be  likened  to  that  by  which  an  orange  seed  is  shot 
from  between  the  fingers. 

LESSON  CCVII 
The  Witch-Hazel 

Leading  thought — The  witch- 
hazel  blossoms  during  the  autumn, 
and  thus  adds  beauty  to  the 
landscape.  It  has  an  interesting 
mechanism  by  which  it  can  shoot 
its  seeds  for  a distance  of  many 
feet. 

Method — This  lesson  divides 
naturally  into  two  parts;  a study 
of  the  way  the  seeds  are  distributed 
is  fitted  for  the  primary  grades, 
and  a study  of  the  flower  for  more 
advanced  grades.  For  the  pri- 
mary grades  the  lesson  should 
begin  by  the  gathering  of  the  twigs 
which  bear  the  fruit.  These  should 
be  brought  to  the  schoolroom — 
there  to  await  results.  Soon  the 
seeds  will  be  popping  all  over  the 
schoolroom,  and  then  the  question 
as  to  how  this  is  done,  and  why, 
may  be  made  the  topic  of  the 
lesson.  For  the  study  of  the  flower 
and  the  shrub  itself,  the  work 
should  begin  in  October  when  the 
blossoms  are  still  in  bud.  As  they 
expand  they  may  be  studied,  a lens  being  necessary  for  observing  the 
interesting  little  doors  to  the  anthers. 

Observations — i.  Is  the  witch-hazel  a shrub  or  a tree? 

2.  What  is  the  color  of  the  bark?  Is  it  thick  or  thin,  rough  or  smooth, 
dark  or  light,  or  marked  with  dots  or  lines  ? Is  there  any  difference  in  color 
between  the  older  wood  and  the  young  twigs?  Is  the  wood  tough  or 
brittle?  Dark  or  light  in  color? 

3 . Do  the  leaves  grow  opposite  each  other  or  alternate  ? On  what  part 
of  the  plant  do  the  leaf  buds  grow?  . 

4 . What  is  the  general  shape  of  the  leaf  ? Is  it  more  pointed  at  the  base 
or  at  the  tip  ? Are  the  leaves  regular  in  form,  or  larger  on  one  side  than  the 
other  ? Are  the  edges  entire*  toothed  or  wavy  ? Are  the  petioles  short  or 
long?  Are  the  veins  straight  or  branching?  Are  they  prominent?  Are 
the  leaves  of  the  same  color  on  both  sides  ? 

5.  Are  there  many  queer-shaped  little  swellings  on  the  leaf  above  and 
below?  See  how  many  of  these  you  can  find?  Tell  what  you  think  they 
are. 

6.  Do  the  flowers  grow  singly  or  in  clusters?  What  is  the  shape  and 
color  of  the  petals,  and  how  many  of  them  are  there  in  each  blossom? 


Tree  Study  813 

Describe  the  calyx.  If  there  are  any  flower  buds  just  opening,  observe  and 
describe  the  way  the  petals  are  folded  within  them. 

7.  How  many  stamens?  With  a lens  observe  the  way  the  two  little 
doors  to  the  anther  fly  open;  how  is  the  pollen  thrown  out?  What  is  the 
shape  of  the  pistil?  How  many  stigmas? 

8.  Does  each  individual  flower  have  a stem  or  is  there  a common  stem 
for  a cluster  of  blossoms  ? Do  the  flowers  grow  at  the  tips  or  along  the  sides 
of  the  twigs?  When  do  the  witch-hazel  flowers  appear  and  how  long  do 
they  last  ? 

9.  Make  a drawing  of  a witch-hazel  nut  before  it  opens.  What  is  the 
color  of  the  outer  husk  when  ripe?  Cut  into  a closed  nut  and  observe  the 
extreme  hardness  and  strength  of  the  inner  shell. 

10.  Where  are  the  seeds  situated?  Can  you  see  that  the  shell,  when 
partially  open,  ready  to  throw  out  the  seeds  resembles  a queer  little  face? 
Describe  the  color  and  marking  of  the  seeds;  are  they  rough  or  smooth? 
How  far  have  you  known  the  witch-hazel  to  throw  its  seeds  ? Study  the 
nut  and  try  to  discover  how  it  throws  the  seeds  so  far.

THE  MOUNTAIN  LAUREL 
Teacher's  Story 

a child  I never  doubted  that  the  laurel  wreaths 
of  Grecian  heroes  were  made  from  mountain 
laurel,  and  I supposed,  of  course,  that  the 
flowers  were  used  also . M y vision  was  of  a hero 
crowned  with  huge  wreaths  of  laurel  bouquets, 
which  I thought  so  beautiful.  It  was  a shock  to 
exchange  this  sumptuous  headgear  of  my 
dreams  for  a plain  wreath  of  leaves  from  the 
green-bay  tree. 

However,  the  mountain  laurel  leaf  is  ever- 
green and  beautiful  enough  to  crown  a victor; 
in  color  it  is  a rich,  lustrous  green  above,  with  a 
yellow  midrib,  the  lower  side  being  of  a much  lighter  color.  In 
shape,  the  leaf  is  long,  narrow,  pointed  at  each  end  and  smooth-edged, 
with  a rather  short  petiole,  The  leaves  each  year  grow  on  the  new 
wood,  which  is  greenish  and  rough,  in  contrast  with  the  old  wood, 
which  is  rich  brownish  red.  The  leaves  are  arranged  below  the  flower 
cluster,  so  that  they  make  a shining  green  base  for  this  natural  bouquet. 

The  flowers  grow  on  the  tips  of  the  branching  twigs,  which  are  huddled 
together  in  a manner  that  brings  into  a mass  many  flowers.  I have  counted 
seventy-five  of  them  in  a single  bunch;  the  youngest  flowers  grow  nearest 
the  tip  of  the  twig.  The  blossom  stems  are  pink,  and  afford  a rich  back- 
ground for  the  starry  open  flowers  and  knobby  closed  buds.  The  bud  of 
the  laurel  blossom  is  very  pretty  and  resembles  a bit  of  rose-colored  pottery ; 
it  has  a five-sided,  pyramidal  top,  and  at  the  base  of  the  pyramid  are  ten 
little  buttresses  which  flare  out  from  the  calyx.  The  calyx  is  five-lobed, 
each  lobe  being  green  at  the  base  and  pink  at  the  point.  Each  one  of  the 


814 


Handbook  of  Nature-Study 


ten  little  buttresses  or  ridges  is  a groove  in  which  a stamen  is  growing,  as 
we  may  see  by  looking  into  an  opening  flower;  each  anther  is  “headed” 
toward  the  pocket  which  ends  the  groove.  The  filament  lengthens  and 
shoves  the  anther  into  the  pocket,  and  then  keeps  on  growing  until  it  forms 
a bow-shaped  spring,  like  a sapling  with  the  top  bent  to  the  ground.  The 
opening  flower  is  saucerlike,  pinkish  white,  and  in  form  is  a five-pointed 
star.  At  the  bottom  of  the  saucer  a ten-pointed  star  is  outlined  in  crimson; 
and  bowed  above  this  crimson  ring  are  the  ten  white  filaments  with  their 
red-brown  anthers  stuffed  cozily  into  the  pockets,  one  pocket  at  the  center 
of  each  lobe,  and  one  half-way  between;  each  pocket  is  marked  with  a 
splash  of  crimson  with  spotty  edges.  From  the 
center  of  the  flower  projects  the  stigma,  far  from  and 
above  the  pollen-pockets. 

Each  laurel  flower  is  thus  set  with  ten  spring-traps 
all  awaiting  the  visit  of  the  unwary  moth  or  bee 
which,  when  seeking  the  nectar  at  the  center  of  the 
flower,  is  sure  to  touch  one  or  all  of  these  bent  fila- 
ments. As  soon  as  one  is  touched,  up  it  springs  and 
slings  its  pollen  hard  at  the  intruder.  The  pollen  is 
not  simply  a shower  of  powder,  but  is  in  the  form  of  a 
sticky  string,  as  if  the  grains  were  strung  on  cobweb 
silk.  When  liberating  these  springs  with  a pencil 
point,  I have  seen  the  pollen  thrown  a distance  of  thirteen  inches;  thus,  if 
the  pollen  ammunition  does  not  strike  the  bee,  it  may  fall  upon  some  open 
flower  in  the  neighborhood.  The  anthers  spring  back  after  this  perform- 
ance and  the  filaments  curl  over  each  other  at  the  center  of  the  flower  below 
the  pink  stigma ; but  after  a few  hours  they  straighten  out  and  each  empty 
anther  is  suspended  above  its  own  pocket.  The  anthers  open  while  in  the 
pocket,  each  one  is  slit  open  at  its  tip  so  that  it  is  like  the  leather  pocket  of  a 
sling. 

After  the  corollas  fall,  the  long  stigma  still  projects  from  the  tip  of  the 
ripening  ovary,  and  there  it  stays,  until  the  capsule  is  ripe  and  open.  The 
five-pointed  calyx  remains  as  an  ornamental  cup  for  the  fruit.  The  capsule 
opens  along  five  valves,  and  each  section  is  stuffed  with  little,  almost 
globular  seeds. 

The  mountain  laurel  grows  in  woods  and  shows  a preference  for  rocky 
mountain  sides  or  sandy  soil. 

Another  of  the  common  species  is  the  sheep  laurel,  which  grows  in 
swampy  places,  especially  on  hillsides.  The  flowers  of  this  are  smaller  and 
pinker  than  the  mountain  laurel,  and  are  set  below  the  leaves  on  the  twig. 
Another  species  called  the  pale,  or  swamp,  laurel,  has  very  small  flowers,  not 
more  than  half  an  inch  in  breadth  and  its  leaves  have  rolled-back  edges  and 
are  whitish  green  beneath.  This  species  is  found  only  in  cold  peat-bogs  and 
swamps 

LESSON  CCVII1 
The  Mountain  Laurel 

Leading  thought — The  laurel  blossom  is  set  with  ten  springs,  and  each 
spring  acts  as  a sling  in  throwing  pollen  upon  visiting  insects,  thus  making 
sure  that  the  visitor  will  carry  pollen  to  other  waiting  flowers. 

Method — Have  the  pupils  bring  to  the  schoolroom  a branch  of  laurei 
which  shows  blossoms  in  all  stages  from  the  bud.  Although  this  lesson  is 
on  the  mountain  laurel,  any  of  the  other  species  will  do  as  well.

Observations — 1.  How  are  the  laurel  leaves  set  about  the  blossom 
clusters  to  make  them  beautiful?  What  is  the  shape  of  the  laurel  leaf? 
What  are  its  colors  above  and  below?  How  do  the  leaves  grow  with 
reference  to  the  flowers?  Do  they  grow  on  last  year’s  or  this  year’s  wood? 
How  can  you  tell  the  new  wood  from  the  old? 

2.  Take  a blossom  bud.  What  is  its  shape ? How  many  sides  to  the 
pyramid-like  tip  ? How  many  little  flaring  ridges  at  the  base  of  the  pyra- 
mid? Describe  the  calyx. 

3.  What  is  the  shape  of  the  flower  when  open?  How  many  lobes  has 
it?  What  is  its  color?  Where  is  it  marked  with  red? 

4.  In  the  open  blossom,  what  do  you  see  of  the  ten  ridges,  or  keels, 
which  you  noticed  in  the  bud  ? How  does  each  one  of  these  grooves  end  ? 
What  does  the  laurel  blossom  keep  in  these  ten  pockets  ? Touch  one  of  the 
ten  filaments  with  a pencil  and  note  what  happens. 

5.  Take  a bud  scarcely  open.  Where  are  the  stamens?  Can  you  see 
the  anthers  ? Take  a blossom  somewhat  more  open.  Where  are  the  anthers

now?  From  these  observations  explain  how  the  stamens  place  their 
anthers  in  the  pockets.  How  do  the  filaments  grow  into  bent  springs?  ' 

6.  Are  the  anthers  open  when  they  are  still  in  the  pocket  ? Look  at  an 
anther  with  a lens  and  tell  how  many  slits  it  has.  How  do  they  open  ? Are 
the  pollen  grains  loose  when  they  are  thrown  from  the  anther?  How  are 
they  fastened  together?  Does  this  pollen  mass  stick  to  whatever  it 
touches  ? 

7.  What  is  the  use  to  the  flower  of  this  arrangement  for  throwing 
pollen?  What  insects  set  free  the  stamen-springs?  Where  is  the  nectar 
which  the  bee  or  moth  is  after?  Can  it  get  this  nectar  without  setting  free 
the  springs  ? Touch  the  filaments  with  a pencil  and  see  how  far  they  will 
sling  the  pollen. 

8.  Describe  the  pistil  in  the  open  flower.  Is  the  stigma  near  the 
anthers?  Would  they  be  likely  to  throw  their  pollen  on  the  stigma  of  their 
own  flower?  Could  they  throw  it  on  the  stigmas  of  neighboring  flowers? 

9.  How  does  the  fruit  of  the  laurel  look?  Does  the  style  still  cling 
after  the  corolla  falls?  Describe  the  fruit-capsule.  How  does  it  open? 
How  do  the  seeds  look?  Are  there  many  of  them? 

10.  Where  does  the  mountain  laurel  grow?  What  kind  of  soil  does  it 
like?  Do  you  know  any  other  species  of  laurel?  If  so,  are  they  found  in 
the  same  situations  as  the  mountain  laurel? 


“A  childish  gladness  stays  my  feet, 

.4$  through  the  winter  woods  I go, 

Behind  some  frozen  ledge  to  meet 

A kalmia  shining  through  the  snow. 

I see  it,  beauteous  as  it  stood 

Ere  autumn's  glories  paled  and  fled, 

And  sigh  no  more  in  pensive  mood, 

‘My  leafy  oreads  are  all  dead.' 

I hear  its  foliage  move,  like  bells 

On  rosaries  strung,  and  listening  there. 

Forget  the  icy  wind  that  tells 

Of  turfless  fields,  and  forests  bare. 

All  gently  with  th'  inclement  scene 
I feel  its  glossy  verdure  blend; — ■ 

I bless  that  lovely  evergreen 

As  heart  in  exile  hails  a friend. 

Its  boughs,  by  tempest  scarcely  stirred, 

A re  tents  beneath  whose  emerald  fold 
The  rabbit  and  the  snowbound  bird 
Forget  the  world  is  white  and  cold. 

And  still,  ’ mid  ruin  undestroyed, 

Queen  arbor  with  the  fadeless  crown, 

Its  brightness  warms  the  frosty  void, 

And  softens  winter's  surliest  frown."

EARTH  AND  SKY 


THE  BROOK 
Teacher's  Story 

“ Little  brook , sing  a song  of  a leaf  that  sailed  along, 

Down  the  golden  braided  center  of  your  current  swift  and  strong.” 

— J.  W.  Riley. 

A brook  is  undoubtedly  the  most  fascinating  bit  of  geography  which  the 
child  encounters ; and  yet  how  few  children  who  happily  play  in  the  brook — ■ 
wading,  making  dams,  drawing  out  the  crayfish  by  his  own  grip  from  his 
lurking  place  under  the  log,  or  watching  schools  of  tiny  minnows — ever 
dream  that  they  are  dealing  with  real  geography.  The  geography  lesson  on 
the  brook  should  not  be  given  for  the  purpose  of  making  work  out  of  play, 
but  to  conserve  all  of  the  natural  interest  in  the  brook,  and  add  to  it  by 
revealing  other  and  more  interesting  facts  concerning  it.  A child  who  thus 
studies  the  brook  will  master  some  of  the  fundamental  facts  of  physical 
geography,  so  that  ever  after  he  will  know  and  understand  all  streams, 
whether  they  are  brooks  or  rivers.  An  interesting  time  to  study  a brook  is 
after  a rain;  and  May  or  October  give  attractive  surroundings  for  the 
study.  However,  the  work  should  be  continued  now  and  then  during  the 
entire  year,  for  each  season  gives  it  some  new  features  of  interest. 

Each  brook  has  its  own  history,  which  can  be  revealed  only  to  the  eyes 
of  those  that  follow  it  from  its  beginning  to  where  it  empties  its  water  into 
a larger  stream  or  pond.  At  its  source  the  brook  usually  is  a small  stream 
with  narrow  banks;  not  until  it  receives  water  from  surrounding  hills  does 
it  gain  enough  power  to  cut  its  bed  deeper  into  the  earth,  thus  making  its 
banks  higher.  Where  it  flows  with  swift  current  down  a hillside,  it  cuts  its 
bed  deeper,  because  swift-moving  water  has  more  power  for  cutting  and 
carrying  away  the  soil.  However,  if  the  hillside  happens  to  be  in  the 
woods,  the  roots  of  trees  or  bushes  will  help  to  keep  the  soil  from  being 
washed  away.  Unless  there  are  obstacles,  the  course  of  the  brook  is  likely 
to  be  more  direct  in  flowing  down  a hillside  than  when  crossing  level  fields. 
The  delightful  way  in  which  brooks  meander  crookedly  across  the  level 
areas  is  due  to  the  inequalities  of  the  surface,  which  interfere  more  with 
water  on  a-  plain  than  on  a hillside,  since  the  gravity  which  pulls  it  forever 
down  has  less  chance  to  act  upon  it  forcibly  in  these  situations.  After  a 
stream  has  thus  started  its  crooked  course,  in  time  of  flood  the  current 
strikes  with  more  force  against  the  curves,  and  cutting  them  deeper,  makes 
the  course  still  more  crooked.  The  places  on  the  banks  where  the  soil  is 
bare  and  exposed  to  the  force  of  the  current,  are  the  points  where  the  banks 
are  cut  most  deeply  at  flood  time. 

But  the  brook  is  not  simply  an  object  to  look  at  and  admire;  it  is  a very 
busy  worker,  its  chief  labor  being  that  of  a digger  and  carrier.  When  it  is 
not  carrying  anything — that  is,  when  its  waters  are  perfectly  clear — the 


Earth  Study 


819 


stream  is  doing  the  least  work.  The  poets,  as  well  as  common  people, 
speak  of  the  playing  of  the  brook  when  its  limpid  waters  catch  the  sun- 
beams on  their  dimpling  surface;  but  when  the  waters  are  roily  the  brook 
is  working  very  hard.  This  usually  occurs  after  a rain,  which  adds  much 
more  water  to  the  volume  of  the  brook;  the  action  of  gravity  upon  this 
larger  and  heavier  body  forces  it  to  flow  more  swiftly  and  every  drop  in  the 
stream  that  touches  the  bank  or  bottom,  snatches  up  a tiny  load  of  earth 
and  carries  it  along.  And  every  drop  thus  laden,  when  it  strikes  against  a 
comer  of  the  bank,  tears  more  soil  loose  through  the  impact,  and  other 
drops  snatch  it  up  and  carry  it  on  down  the  stream.  And  after  a time 
there  are  so  many  drops  carrying  loads  and  bumping  along,  knocking  loose 
more  earth,  that  the  whole  brook,  which  is  made  up  of  drops,  looks  muddy. 
In  its  work  as  a digger,  every  drop  of  water  that  touches  the  soil  at  the 
bottom  or  on  the  banks  of  the  brook  uses  its  own  little  load  of  earth  or 
gravel  as  a crowbar  or  pickaxe  to  pry  up  other  bits  of  dirt  and  gravel ; and 
all  of  the  drops  hastening  on,  working  hard  together,  dig  the  channel  of  the 
brook  wider  and  deeper  In  some  steep  places,  so  many  of  the  drops  are 
working  together  that  they  are  able  .to  pick  up  pebbles  or  stones,  with 
which  they  batter  and  tear  down  larger  pieces  of  the  bank  and  scrape  out 
greater  holes  in  the  bottom  of  the  stream.  On  and  on  the  brook  flows,  a 
gang  of  workmen  each  of  which  is  using  its  own  load  as  a tool,  all  in  close 
procession  and  working  double  quick.  But  as  soon  as  the  brook  reaches  a 
plain  or  level,  its  activity  ceases;  the  drops  act  tired  and  seem  to  have  no 
ambition  to  pick  up  more  soil,  and  each  lets  fall  its  own  load  as  soon  as 
possible,  dropping  the  larger  pieces  of  gravel  and  rock  first,  carrying  the 
finer  soil  farther,  but  finally  letting  that  down  also.  If  we  examine  the 
sediment  of  a flooded  brook,  we  find  that  the  gravel  is  always  dropped  first, 
and  that  the  fine  mud  is  carried  farthest  before  it  is  deposited. 

The  roar  of  a flooded  stream  is  very  different  from  the  murmur  of  its 
waters  when  they  are  low.  It  is  not  to  be  wondered  at,  when  we  once  think 
of  all  that  is  going  on  in  the  brook  during  periods  of  flood.  There  are  some 
s mple  experiments  to  show  what  the  force  of  water  can  do  when  turned 
against  the  soil.  Pour  water  from  a pitcher  into  a bed  of  soft  soil,  and  note 
how  quickly  a hole  will  be  made ; if  the  pitcher  is  held  near  the  soil,  less  of  a 
hole  will  be  formed  than  if  the  pitcher  is  held  high  up,  which  shows  that  the 
farther  the  water  falls,  the  greater  is  its  force.  This  explains  why  the  banks 
of  streams  are  undermined  when  a strong  current  is  driven  against  them. 
The  swift  current,  of  course,  breaks  away  more  earth  at  bends  and  curves 
than  when  it  is  flowing  in  a straight  line;  for  ordinarily,  when  flowing 
straight,  the  current  is  swiftest  in  the  bed  of  the  stream,  and  is  therefore 
only  digging  at  the  bottom ; but  when  it  flows  around  curves,  it  is  directed 
against  the  banks,  and  therefore  has  much  more  surface  to  work  upon. 
Thus  it  is  that  bends  are  cut  deeper  and  deeper.  If  the  bare  arm  is  thrust 
into  a flooded  brook,  we  find  that  many  pieces  of  gravel  strike  against  it; 
and  if  we  reach  the  bottom,  we  can  feel  the  pebbles  being  moved  along  over 
the  brook  bed. 

LESSON  CCIX 
The  Brook 

Leading  thought — The  water  from  the  little  brook  near  our  schoolhouse  is 
flowing  toward  the  ocean,  and  is  meanwhile  digging  out  and  carrying  along 
with  it  the  soil  through  which  it  flows.

Method — The  best  time  to  study  a brook  is  after  a rain,  and  October  or 
May  is  an  interesting  time  for  beginning  this  lesson.  The  work  should  be 
continued  during  the  entire  year.  It  may  be  done  at  noon  or  recess,  if  the 
brook  is  near  at  hand;  or  there  may  be  excursions  after  school,  if  the  brook 
is  at  some  distance.  The  observations  should  be  made  by  the  class  as  a 
whole. 

Observations — i.  Does  the  brook  have  its  source  in  a spring  or  a 
swamp,  or  does  it  receive  its  water  as  drainage  from  surrounding  hills? 
Follow  it  back  to  its  very  beginning.  Do  you  find  this  in  open  fields  or 
woods?  Is  the  land  about  it  level  or  hilly? 

2 . Are  its  banks  deeper  at  the  beginning,  or  is  the  brook  at  first  almost 
on  a level  with  the  surrounding  fields?  Do  the  banks  become  deeper 
farther  from  the  source  ? Are  the  banks  higher  where  the  brook  flows  down 
hill,  or  where  it  is  on  a level? 

3 . Is  the  course  of  the  brook  more  crooked  on  a hillside  or  when  flowing 
through  a level  area?  Are  the  banks  more  worn  away  and  steep  where  the 
brook  flows  through  woods  or  bushes  than  through  the  open  fields  ? 

4.  Can  you  find  the  places  where  the  water  is  cutting  the  banks  most, 
when  the  brook  is  flooded?  Why  does  it  cut  the  banks  at  these  particular 
points  ? 

5.  Into  what  stream,  pond  or  lake  does  the  brook  flow?  If  you  should 
launch  a toy  boat  upon  the  waters  of  this  brook,  and  it  should  keep  afloat, 
through  what  streams  would  it  pass  to  reach  the  ocean?  Through  what 
townships,  counties,  states  or  countries  would  it  pass  ? 

6.  When  is  the  brook  working  and  when  is  it  playing?  What  is  the 
difference  between  the  color  of  the  water  ordinarily  and  when  the  brook  is 
flooded?  What  causes  this  difference?

7.  Make  the  following  experiment  to  show  what  the  brook  is  carrying 
after  a storm  when  the  water  is  roily.  Dip  from  the  swift  portion  of  the 
stream  a glass  fruit  jar  full  of  water.  Place  it  on  a window-sill  and  do  not 
disturb  it  until  the  water  is  clear.  How  much  sediment  has  settled  at  the 
bottom  of  the  jar?  Where  was  this  sediment  when  you  dipped  up  the 
water?  If  this  quart  of  water  could  carry  so  much  soil  or  sediment,  how 
much,  do  you  think,  would  the  whole  brook  carry  ? 

8.  Where  did  the  brook  get  the  soil  to  make  the  water  roily  ? Study 
its  banks  in  order  to  answer  this  question.  Do  you  think  the  soil  in  the 
water  came  from  the  banks  that  are  covered  by  vegetation  or  from  those 
which  are  bare? 

9.  How  did  the  brook  pick  up  the  soil  that  it  carried  when  it  was 
flooded?  Do  you  think  that  one  of  the  tools  that  the  brook  digs  with  is 
the  current?  Try  to  find  a place  where  the  swift  current  strikes  the  bank, 
and  note  if  the  latter  is  being  worn  away. 

10.  Does  the  swift  current  take  more  soil  where  it  is  flowing  straight, 
or  where  there  are  sharp  bends  ? How  are  the  bends  in  the  brook  or  creek 
made? 

1 1 . Thrust  your  bare  hand  or  arm  into  the  swift  current  of  the  brook 
when  it  is  flo’oded.  Do  you  feel  the  gravel  strike  against  your  arm  or  hand  ? 
Wade  in  the  water.  Do  you  feel  the  pebbles  strike  against  the  feet  or  legs, 
as  they  are  being  rolled  along  the  bed  of  the  stream? 

12.  Does  the  water,  loaded  with  soil  and  pebbles,  dig  into  the  banks 
more  vigorously  than  just  the  water  alone  could  do  ? Which  washes  away 
more  earth  and  carries  it  down  stream — a fast  or  a slow  current  ? 

13 . Does  the  water  of  the  brook  flow  fastest  when  its  waters  are  low  or 
high?  When  the  brook  is  at  its  highest  flood,  do  you  think  it  is  working 
the  hardest?  If  so,  explain  why?  When  it  is  working  the  hardest  and 
carrying  most  soil  and  gravel,  does  it  make  a different  sound  than  when  it  is 
flowing  slowly  and  its  waters  are  clear? 

14.  How  does  the  brook  look  when  it  is  doing  the  least  amount  of  work 
possible? 

15  Make  a map  of  your  brook  showing  every  pool,  indicating  the 
places  where  the  current  is  swiftest  and  showing  the  bends  in  its  course. 
To  test  the  rapidity  of  the  current,  put  something  afloat  on  it  and  measure 
how  far  it  will  go  in  a minute. 

16.  How  many  kinds  of  trees,  bushes  and  plants  grow  along  the  banks 
of  your  brook  ? How  many  kinds  of  fish  and  insects  do  you  find  living  in  it  ? 
How  many,  kinds  of  birds  do  you  see  frequently  near  it  ? 

A brook  puzzle  for  pupils  to  solve — When  we  have  a load  to  carry  we  go 
slowly  because  we  are  obliged  to ; and  the  heavier  the  load,  the  slower  we 
go.  On  the  other  hand,  when  we  wish  to  run  very  swiftly  we  drop  the  load 
so  as  not  to  be  weighted  down;  when  college  or  high  school  boys  run  races 
in  athletic  games,  they  do  not  wear  even  their  ordinary  clothing,  but  dress 
as  lightly  as  possible  in  trunks  and  tights;  they  also  train  severely  so  that 
they  do  not  have  to  carry  any  more  flesh  on  their  bones  than  is  necessary. 
How  is  it  that  in  the  case  of  a brook  just  opposite  is  true?  The  faster  the 
brook  runs,  the  more  it  can  carry;  and  the  heavier  it  becomes  the  faster  it 
runs ; and  the  faster  it  runs  the  more  work  it  can  do.

Where  the  stream  drops  its  load. 

HOW  A BROOK  DROPS  ITS  LOAD 
Teacher's  Story 

The  brook  is  most  discriminating  in  the  way  it  takes  up  its  burdens,  and 
also  in  the  way  it  lays  them  down.  It,  with  quite  superhuman  wisdom, 
selects  the  lightest  material  first,  leaving  the  heaviest  to  the  last;  and  when 
depositing  the  load,  it  promptly  drops  the  heaviest  part  first.  And  thus 
the  flowing  waters  of  the  earth  are  eternally  lifting,  selecting,  and  sifting 
the  soils  on  its  surface. 

The  action  of  rain  upon  the  surface  of  the  ground  is  in  itself  an  excellent 
lesson  in  erosion.  If  there  is  on  a hillside  a bit  of  bare  ground  which  has 
been  recently  cultivated  or  graded,  we  can  plainly  see,  after  a heavy  rain, 
where  the  finer  material  has  been  sorted  out  and  carried  away,  leaving  the 
larger  gravel  and  stones.  And  if  we  examine  the  pools  in  the  brook,  we 
shall  find  deltas  as  well  as  many  examples  of  the  way  the  soil  is  sifted  as  it  is 
dropped.  The  water  of  a rill  flowing  through  pasture  and  meadow  is 
clear,  even  after  a hard  rain.  This  is  owing,  not  so  much  to  the  fact  that 
the  roots  hold  the  banks  of  the  brook  firmly,  as  that  the  grass  on  the  surface 
of  the  ground  acts  as  a mulch  and  protects  the  soil  from  the  erosive  impact 
of  the  raindrops.  On  the  other  hand,  and  for  a reverse  reason,  a rill 
through  plowed  ground  is  muddy.  On  a hillside,  therefore,  contour  plow- 
ing is  practiced — that  is,  plowing  crosswise  the  hillside  instead  of  up  and 
down.  When  the  furrow  is  carried  crosswise,  the  water  after  showers  can 
not  dash  away,  carrying  off  in  it  all  the  finer  and  more  fertile  portions  of  the 
soil.  There  are  many  instances  in  our  Southern  States  where  this  difference 
in  the  direction  of  plowing  has  saved  or  destroyed  the  fertility  of  hillside 
farms. 

The  little  experiment  suggested  at  the  beginning  of  the  following  lesson, 
should  show  the  pupils  clearly  the  following  points : It  is  through  motion 

that  water  takes  up  soil  and  holds  it  in  suspension.  The  tendency  of  still 


Earth  Study 


823 


water  is  to  drop  all  the  load  which  it  is  carrying  and  it  drops  the  heaviest 
part  first.  We  find  the  pebbles  at  the  bottom  of  the  jar,  the  sand  and 
gravel  next,  and  the  fine  mud  on  top.  The  water  may  become  perfectly 
clear  in  the  jar  and  yet,  when  stirred  a little,  it  will  become  roily  again 
because  of  the  movement.  Every  child  who  wades  in  a brook,  knows  that 
the  edges  and  the  still  pools  are  more  comfortable  for  the  feet  than  is  the 
center  of  the  stream  under  the  swift  current.  This  is  because,  where  the 
water  is  less  swift  at  the  sides,  it  deposits  its  mud  and  makes  a soft  bottom; 
while  under  the  swifter  part  of  the  current,  mud  is  washed  away  leaving 
the  larger  stones  bare.  For  the  same  reason,  the  bottom  of  a stream  cross- 
ing a level  field  is  soft,  because  the  silt,  washed  down  from  the  hills  by  the 
swift  current,  is  dropped  when  the  waters  come  to  a more  quiet  place.  If, 
across  a stony  brook,  the  pupils  can  build  a dam  that  will  hold  for  two  or 
three  months  in  the  fall  or  spring  when  the  brook  is  flooded,  they  will  be 
able  to  note  that  the  stones  will  soon  be  more  or  less  covered  with  soft  mud; 
for  the  dam,  stopping  the  current,  causes  the  water  to  drop  its  load  of  silt. 
It  would  have  to  be  a very  recently  made  pool  in  a stream,  which  would  not 
have  a soft  mud  bottom.  The  water  at  times  of  flood  is  forced  to  the  side 
of  the  streams  in  eddies,  and  its  current  is  thus  checked,  and  its  load  of  mud 
dropped. 

It  should  be  noted  that  at  points  where  the  brook  is  narrowest  the  cur- 
rent is  swiftest,  and  where  the  current  is  swiftest  the  bottom  is  more  stony. 
Also,  where  there  is  a bend  in  the  stream  the  brook  digs  deeper  into  the 
bank  where  it  strikes  the  curve,  and  much  of  the  soil  thus  washed  out  is 
removed  to  the  other  side  of  the  stream  where  the  current  is  very  slow,  and 
there  is  dropped.  (See  Introduction  to  Physical  Geography,  Gilbert  and 
Brigham,  pp.  51  and  52.)  If  possible,  note  that  where  a muddy  stream 
empties  into  a pond  or  lake,  the  waters  of  the  latter  are  made  roily  for  some 
distance  out,  but  beyond  this  the  water  remains  clear.  The  pupils  should 
be  made  to  see  that  the  swift  current  of  the  brook  is  checked  when  its 
waters  empty  into  a pond  or  lake,  and  because  of  this  they  drop  their  load. 
This  happens  year  after  year,  and  a point  extending  out  into  the  lake  or 
pond  is  thus  built  up.  In  this  manner  the  great  river  deltas  are  formed.

LESSON  CCX 

How  a Brook  Drops  Its  Load 

Leading  thought — The  brook  carries  its  load  only  when  it  is  flowing 
rapidly.  As  soon  as  the  current  is  checked,  it  drops  the  larger  stones  and 
gravel  first  and  then  the  finer  sediment.  It  is  thus  that  deltas  are  built  up 
where  streams  empty  into  lakes  and  ponds. 

Method — Study  the  rills  made  in  freshly  graded  soil  directly  after  a 
heavy  rain.  Ask  the  pupils  individually  to  make  observations  on  the 
flooded  brook. 

Experiment — Take  a glass  fruit  jar  nearly  full  of  water  from  the  brook, 
add  gravel  and  small  stones  from  the  bed  of  the  brook,  sand  from  its  borders 
and  mud  from  its  quiet  pools.  Have  it  brought  into  the  schoolroom,  and 
shake  it  thoroughly.  Then  place  in  a window  and  ask  the  pupils  to  observe 
the  following  things: 


824 


Handbook  of  Nature-Study 


(a)  Does  the  mud  begin  to  settle  while  the  water  is  in  motion;  that  i?, 
while  it  is  being  shaken? 

(b)  As  soon  as  it  is  quiet,  does  the  settling  process  begin? 

(c)  Which  settles  first — the  pebbles,  the  sand  or  the  mud?  Which 
settles  on  top — that  is,  which  settles  last  ? 

(d)  Notice  that  as  long  as  the  water  is  in  the  least  roily,  it  means  that 
the  soil  in  it  has  not  all  settled;  if  the  water  is  disturbed  even  a little  it 
becomes  roily  again,  which  means  that  as  soon  as  the  water  is  in  motion  it 
takes  up  its  load. 

Observations — 1.  Where  is  the  current  swiftest,  in  the  middle  or  at  the 
side  of  the  stream  ? 

2 . What  is  the  difference,  in  the  bottom  of  the  brook,  between  the  place 
below  the  swift  current  and  the  edges?  That  is,  if  you  were  wading  in  the 
brook,  where  would  it  be  more  comfortable  for  your  feet — at  the  sides  or  in 
the  swiftest  part  of  the  current?  Why? 

3 . Does  the  brook  have  a more  stony  bed  where  it  flows  down  a hillside 
than  where  flowing  through  a level  place? 

4.  Place  a dam  across  your  brook  where  the  bottom  is  stony,  and  note 
how  soon  it  will  have  a soft  mud  bottom.  Why  is  this? 

5.  Can  you  find  a still  pool  in  your  brook  that  has  not  a soft,  muddy 
bottom?  Why  is  this? 

6.  Does  the  brook  flow  more  swiftly  in  the  steep  and  narrow  places 
than  in  the  wide  portions  and  where  it  is  dammed  ? 

7 . Do  you  think  if  water,  flowing  swiftly  and  carrying  a load  of  mud, 
were  to  come  to  a wider  or  more  level  place,  like  a pool  or  millpond  dam, 
that  it  would  drop  some  of  its  load?  Why? 

8.  If  the  water  flows  less  swiftly  along  the  edges  than  in  the  middle, 
would  this  make  the  bottom  below  softer  and  more  comfortable  to  the  feet 
than  where  the  current  is  swiftest?  If  so,  why? 

9.  If  you  can  see  the  place  where  a brook  empties  into  a pond  or  lake, 
how  does  it  make  the  waters  of  the  latter  look  after  a storm?  What  is  the 
water  of  the  brook  doing  to  give  this  appearance,  and  why? 

10.  What  becomes  of  the  soil  dropped  by  the  brook  as  it  enters  a pond 
or  lake?  Do  you  know  of  any  points  of  land  extending  out  into  a lake  or 
pond  where  the  stream  enters  it  ? What  is  a stream  delta? 

“In  the  bottom  .of  the  valley  is  a brook  that  saunters  between  oozing  banks.  It  falls  over 
stones  and  dips  under  fences.  It  marks  an  open  place  on  the  face  of  the  earth , and  the  trees 
and  soft  herbs  bend  their  branches  into  the  sunlight.  The  hangbird  swings  her  nest  over  it. 
Mossy  logs  are  crumbling  into  it.  There  are  still  pools  where  the  minnows  play.  The  brook 
runs  away  and  away  into  the  forest.  As  a boy  I explored  it  but  never  found  its  source.  It 
came  somewhere  from  the  Beyond  and  its  name  was  Mystery. 

The  mystery  of  this  brook  was  its  changing  moods.  It  had  its  own  way  of  recording  the 
passing  of  the  weeks  and  months.  I remember  never  to  have  seen  it  twice  in  the  same  mood , 
nor  to  have  got  the  same  lesson  from  it  on  two  successive  days:  yet, with  all  its  variety , it  always 
left  that  same  feeling  of  mystery  and  that  same  vague  longing  to  follow  to  its  source  and  to  know 
the  great  world  that  I was  sure  must  lie  beyond.  I felt  that  the  brook  was  greater  and  wiser 
than  I.  It  became  my  teacher.  I wondered  how  it  knew  when  March  came , and  why  its 
round  of  life  recurred  so  regularly  with  the  returning  seasons.  I remember  that  I was 
anxious  for  the  spring  to  come,  that  I might  see  it  again.  I longed  for  the  earthy  smell  when 
the  snow  settled  away  and  left  bare  brown  margins  along  its  banks.  I watched  for  the  suck- 
ers that  came  up  from  the  river  to  spawn.  I made  a note  when  the  first  frog  peeped.  I waited 
for  the  unfolding  spray  to  soften  the  bare  trunks.  I watched  the  greening  of  the  banks  and 
looked  eagerly  for  the  bluebird  when  I heard  his  curling  note  somewhere  high  in  the  air."

CRYSTAL  GROWTH 
Teacher's  Story 

To  watch  the  growth  of  a crystal  is  to  witness  a 
miracle;  involuntarily  we  stand  in  awe  before  it, 
as  a proof  that  of  all  truths  mathematics  is  the 
most  divine  and  inherent  in  the  universe.  The 
teacher  will  fail  to  make  the  best  use  of  this  lesson 
if  she  does  not  reveal  to  the  child  through  it  some- 
thing of  the  marvel  of  crystal  growth. 

That  a substance  which  has  been  dissolved  in 
water  should,  when  the  water  evaporates,  assem- 
ble its  particles  in  solid  form  of  a certain  shape, 
with  its  plane  surfaces  set  exactly  at  certain  A snow  crystaL 
angles  one  to  another,  always  the  same  whether  Photomicrograph  by  w.  a. 
the  crystal  be  large  or  small,  is  quite  beyond  our 

understanding  Perhaps  it  is  no  more  miraculous  than  the  growth  of  living 
beings , but  it  seems  so.  The  fact  that  when  an  imperfect  crystal,  unfinished 
or  broken,  is  placed  in  water  which  is  saturated  with  the  same  substance,  it 
will  be  built  out  and  made  perfect,  shows  a law  of  growth  so  exquisitely 
exemplified  as  to  again  make  us  glad  to  be  a part  of  a universe  so  perfectly 
governed.  Moreover,  when  crystals  show  a variation  in  numbers  of  angles 
and  planes  it  is  merely  a matter  of  division  or  multiplication.  A snow 
crystal  is  a six-rayed  star,  yet  sometimes  it  has  three  rays. 

The  window-sill  of  a schoolroom  may  be  a place  for  the  working  of 
greater  wonders  than  those  claimed  by  the  astrologists  of  old,  when  they 
transmuted  baser  metals  to  gold  and  worthless  stones  to  diamonds.  It 
may  be  a place  where  strings  of  gems  are  made  before  the  wondering  eyes  of 
the  children;  gems  fit  to  make  necklaces  for  any  naiad  of  the  brook  or 
oread  of  the  caves. 

It  adds  much  to  the  interest  of  this  lesson  if  different  colored  substances 
are  used  for  the  forming  of  the  crystals.  Blue  vitriol,  potassium  bichro- 
mate, and  alum  give  beautiful  crystals,  contrasting  in  shape  as  well  as  in 
colors. 

Copper  sulphate  and  blue  vitriol  are  two  names  for  one  substance;  it  is 
a poison  when  taken  internally  and,  therefore,  it  is  best  for  the  teacher  to 
carry  on  the  experiment  before  the  pupils  instead  of  trusting  the  substance 
to  them  indiscriminately.  Blue  vitriol  forms  an  exquisitely  beautiful  blue 
crystal,  which  is  lozenge-shaped  with  oblique  edges.  Often,  as  purchased 
from  the  drug  store,  we  find  it  in  the  form  of  rather  large,  broken,  or  imper- 
fect crystals.  One  01  the  pretty  experiments  is  to  place  some  of  these  broken 
crystals  in  a saucer  containing  a saturated  solution  of  the  vitriol,  and  note 
that  they  straightway  assert  crystal  nature  by  building  out  the  broken 
places,  and  growing  into  perfect  crystals.  Blue  vitriol  is  used  much  in  the 
dying  and  in  the  printing  of  cotton  and  linen  cloths.  It  has  quite  wonderful 
preservative  qualities;  if  either  animal  or  vegetable  tissues  are  permeated 
by  it  they  will  remain  dry  and  unchanged. 

Potassium  bichromate  is  also  a poison  and,  therefore,  the  teacher  should 
make  the  solution  in  the  presence  of  the  class.  It  forms  orange-red  crystals, 
more  or  less  needle-shaped.  It  crystallizes  so  readily  that  if  one  drop  of  the 
so'ution  be  placed  on  a saucer  the  pupils  may  see  the  formation  of  the 
crystals  by  watching  it  for  a few  moments  through  a lens.

Handbook  of  Nature-Study 


The  common  alum  we  buy  in  crystal  form,  however,  it  is  very  much 
broken.  Its  crystals  are  eight-sided  and  pretty.  Alum  is  widely  used  in 
dyes,  in  medicines,  and  in  many  other  ways.  It  is  very  astringent,  as  every 
child  knows  who  has  tried  to  eat  it,  and  has  found  the  lips  and  tongue  much 
puckered  thereby 

Although  we  are  more  familiar  with  crystals  formed  from  substances 
dissolved  in  water,  yet  there  are  some  minerals,  like  iron  which  crystallize 
only  when  they  are  melted  by  heat;  and  there  are  other  crystals,  like  the 
snow,  which  are  formed  from  vapor.  Thus,  substances  must  be  molten 
hot,  or  dissolved  in  a liquid,  or  in  form  of  gas,  in  order  to  grow  into  crystals. 

LESSON  CCXI 
Crystal  Growth 

Leading  thought — Different  substances  when  dissolved  in  water  will 
re-form  as  crystals;  each  substance  forms  crystals  of  its  own  peculiar  color 
and  shape. 

Method — Take  three  test  tubes,  long  vials  or  clear  bottles.  Fill  one 
with  a solution  made  by  dissolving  one  part  of  blue  vitriol  in  three  parts  of 
water;  fill  another  by  dissolving  one  part  of  bichromate  of  potash  with 
twenty-five  parts  of  water;  fill  another  'with  one  part  of  alum  in  three 
parts  of  water.  Suspend  from  the  mouth  of  each  test  tube  or  vial,  a piece  of 
white  twine,  the  upper  end  tied  to  a tooth  pick,  which  is  placed  across  the 
mouth  of  the  vial;  the  other  end  should  reach  the  bottom  of  the  vial.  If 
necessary,  tie  a pebble  to  the  lower  end  so  that  it  will  hang  straight.  Place 
the  bottles  on  the  window  sill  of  the  schoolroom,  where  the  children  may 
observe  what  is  happening.  Allow  them  to  stand  for  a time,  until  the 
string  in  each  case  is  encrusted  with  crystals ; then  pull  out  the  string  and 
the  crystals.  Dry  them  with  a blotter,  and  let  the  children  observe  them 
closely.  Care  should  be  taken  to  prevent  the  children  from  trying  to  eat 
these  beautiful  crystals,  by  telling  them  that  the  red  and  blue  crystals  are 
poisonous. 

Observations — i.  In  which  bottle  did  the  crystals  form  first?  Which 
string  is  the  heaviest  with  the  crystals  ? 

2.  What  was  the  color  of  the  water  in  which  the  blue  vitriol  was 
dissolved?  Is  it  as  brilliant  in  color  now  as  it  was  when  it  was  first  made? 
Do  you  think  that  the  growth  of  the  crystals  took  away  from  the  blue 
material  of  the  water?  Look  at  the  blue  vitriol  crystals  with  a lens,  and 
describe  their  shape.  Are  the  shapes  of  the  large  crystals  of  the  vitriol  the 
same  as  those  of  the  small  ones? 

3.  What  is  the  shape  of  the  crystals  of  the  potassium  bichromate? 
What  is  the  color  ? Are  these  crystals  as  large  as  those  of  the  blue  vitriol  or 
of  the  alum? 

4.  What  shapes  do  you  find  among  the  crystals  of  alum? 

5.  Do  you  think  that  vitriol  and  potassium  bichromate  and  alum 
will,  under  favorable  circumstances,  always  form  each  its  own  shape  of 
crystal  wherever  it  occurs  in  the  world?  Do  you  think  crystals  could  be 
formed  without  the  aid  of  water?

SALT 

Teacher's  Story 

A “saturated  solution”  is  an  uninspiring  term  to  one 
not  chemically  trained;  and  yet  it  merely  means  water 
which  holds  as  much  as  it  can  take  of  the  dissolved  sub- 
stance; if  the  water  is  hot,  it  disso  vesmore  of  most  sub- 
stances. To  make  a saturated  solution  of  salt  we  need  two 
parts  of  salt  or  a little  more,  for  good  measure,  to  five  parts 
of  water;  the  water  should  be  stirred  until  it  will  take  up 
no  more  salt. 

A slip  of  paper  placed  in  a saucer  of  this  solution  will  prove  a resting 
place  for  the  crystals  as  they  form.  In  about  two  days  the  miracle  will  be 
working,  and  the  pupils  should  now  and  then  observe  its  progress.  Those 
saucers  set  in  a draft  or  in  a warm  place  will  show  crystals  sooner  than 
others,  but  the  crystals  will  be  smaller;  for  the  faster  a crystal  grows,  the 
smaller  is  its  stature.  If  the  water  evaporates  rapidly,  the  crystals  are 
smaller,  because  so  many  crystals  are  started  which  do  not  have  material 
for  large  growth.  When  the  water  is  evaporated,  to  appreciate  the  beauty 
o f the  crystals  we  should  look  at  them  with  a lens  or  microscope.  Each 
crystal  is  a beautiful  little  cube,  often  with  a pyramid-shaped  depression  in 
each  face  or  side.  After  the  pupils  have  seen  these  crystals,  the  story  of 
where  salt  is  found  should  be  told  them. 

Salt  is  obtained  by  two  methods:  by  mining  large  deposits  of  rock  salt, 
and  by  evaporating  water  containing  a strong  solution  of  salt.  The  oldest 
salt  works  in  this  country  are  in  Syracuse,  New  York,  where  the  salt  comes 
from  salt  springs  which  were  famous  among  the  American  Indians.  At 
Ithaca,  N.  Y.,  the  salt  deposits  are  about  2000  feet  below  the  surface  of  the 
earth.  Water  is  forced  down  into  the  stratum  of  rock,  which  was  evidently 
once  the  bottom  of  a briny  sea ; the  water  dissolves  the  salt,  and  it  is  then 
pumped  up  to  the  surface  and  evaporated,  leaving  the  salt  in  crystals.  In 
Michigan  and  Louisiana  there  are  other  large  salt  works  of  a similar 
character.  The  largest  salt  mines  in  the  world  are  those  in  Poland,  which 
have  been  used  for  hundreds  of  years.  In  these  mines  there  are  fifty  miles 
of  corridors,  and  the  salt  has  been  carved  Into  beautiful  chambers  with 
statues  and  other  decorations,  all  cut  from  the  solid  salt.  One  of  these 
chambers  represents  a chapel  beautifully  ornamented. 

When  the  United  States  was  first  settled,  salt  was  brought  over  from 
England;  but  this  was  so  expensive  that  people  could  not  afford  it  and 
they  soon  began  to  make  their  own  salt  by  evaporating  sea  water  in  kettles 
on  the  beach.  In  those  countries  where  it  is  scarce,  salt  is  said  to  be  literally 
worth  its  weight  in  gold.  The  necessity  for  salt  to  preserve  the  health  of 
both  people  and  animals  has  tempted  the  governments  of  some  countries  to 
place  a special  tax  upon  it;  in  Italy,  especially,  the  poor  people  suffer 
greatly  on  account  of  the  high  price  of  salt  from  this  cause. 

Salt  lakes  are  found  in  natural  basins  of  arid  lands,  and  are  always  with- 
out outlets.  The  water  which  runs  in  escapes  by  evaporation,  but  the  salt 
it  brings  cannot  escape,  and  accumulates.  A salt  lick  is  a place  where  salt 
is  found  on  the  surface  of  the  earth,  usually  near  a salt  spring.  Animals 
will  travel  a long  distance  to  visit  a salt  lick  which  gained  its  name  through 
their  attentions.

LESSON  CCXII 
Salt 

Leading  thought — Salt  dissolves  in  water,  and  as  the  water  evaporates 
the  salt  appears  in  beautiful  crystals. 

Method — Let  each  pupil,  if  possible,  have  a cup  and  saucer,  a square  of 
paper  small  enough  to  go  into  the  saucer,  some  salt  and  water.  Let  each 
pupil  take  five  teaspoonfuls  of  water  and  add  to  this  two  spoonfuls  of  salt, 
stirring  the  mixture  until  dissolved.  When  the  water  will  take  no  more  salt 
let  each  pupil  write  his  name  and  the  date  on  the  square  of  paper,  lay  it  in 
the  saucer,  pressing  it  down  beneath  the  surface.  Let  some  place  their 
saucers  in  a warm  place,  others  where  they  may  be  kept  cool,  and  others  in  a 
draft.  If  it  is  impossible  for  each  pupil  to  have  a saucer,  two  or  three  pupils 
may  be  selected  to  perform  the  experiments. 

Observations — i.  When  you  pour  the  salt  into  the  water,  what  becomes 
of  it?  How  do  you  know  when  the  water  will  hold  no  more  salt? 

2 . After  a saucer,  filled  with  the  salt  water,  stands  exposed  to  the  air  for 
several  days,  what  becomes  of  the  water?  From  which  saucers  did  the 
water  evaporate  fastest — those  in  the  warm  places,  or  those  in  the  cold? 
In  which  did  the  crystals  form  first? 

3 . Which  saucers  contained  the  largest  crystals — those  from  which  the 
water  evaporated  first,  or  those  from  which  it  evaporated  more  slowly? 

4.  Could  you  see  how  the  crystals  began?  What  is  the  shape  of  the 
perfect  salt  crystal  ? Do  the  smallest  crystals  have  the  same  shape  as  the 
largest  ones  ? 

5 . What  happens  to  people  who  cannot  get  salt  to  eat  ? 

6.  How  is  dairy  salt  and  table  salt  obtained?  What  is  rock  salt? 
What  are  salt  licks  ? Where  are  the  salt  mines  found  ? Why  .is  the  ocean 
called  “the  briny  deep?” 

7.  Name  and  locate  the  salt  lakes.  Why  are  lakes  salt? 

LESSON  CCXIII 
How  to  Study  Minerals 

Many  children  are  naturally  interested  in 
stones.  I once  knew  two  children,  aged  seven  and 
five,  who  could  invariably  select  the  boulders  and 
pebbles  of  metamorphic  rock  in  the  region  about 
Ithaca.  They  also  could  tell,  when  the  pebbles 
were  broken,  which  parts  were  quartz  and  which 
mica.  They  had  incidentally  asked  about  one  of 
these  stones,  and  I had  told  them  the  story  of  the 
glacial  period  and  how  these  stones  were  torn 
away  from  the  mountains  in  Canada  and  brought 
down  by  ice  and  dropped  in  Ithaca.  It  was  a 
story  they  liked,  and  their  interest  in  these  granite 
voyagers  was  always  a delightful  element  of  our  walks  in  the  field. 

For  the  pupils  in  the  elementary  grades  it  seems  best  to  limit  the  study 
of  minerals  to  those  which  make  up  our  granite  and  common  rocks.  In 
order  to  teach  about  these  minerals  well,  the  teacher  should  have  at  least 
one  set  of  labelled  specimens.  Such  a collection  may  be  obtained  from 
Edward  E.  Howell,  612  17th  St.,  N.  W.,  Washington,  D.  C.,  and  also  from

Ward’s  Natural  Science  Establishment,  College  Avenue  Rochester,  N.  Y. 
These  collections  vary  in  number  of  specimens  and  price  from  one  to  two 
dollars  and  are  excellent.  The  teacher  should  have  one  or  two  perfect 
crystals  of  quartz,  feldspar  and  calcite.  An  excellent  practice  for  a boy  is 
to  copy  these  crystals  in  wood  for  the  use  of  the  teacher. 

The  physical  characteristics  used  in  identifying  minerals  are  briefly  as 
follows : 

1.  Form.  This  may  be  crystalline,  which  shows  the  shape  of  the 
crystals  definitely;  granular,  like  marble,  the  grains  having  the  internal 
structure,  but  not  the  external  form,  of  crystals;  compact,  which  is  without 
crystalline  form,  as  limestone  or  flint. 

2.  Color. 

3.  Luster  or  shine , which  may  be  glassy  like  quartz,  pearly  like  the 
inside  of  a shell;  silky  like  asbestos;  dull;  or  metallic  like  gold. 

4.  Hardness  or  resistance  to  scratching,  thus : Easily  scratched  with 
the  finger  nail;  cannot  be  scratched  by  the  finger  nail;  easily  scratched 
with  steel ; with  difficulty  scratched  with  steel ; not  to  be  scratched  by 
steel.  A pocket  knife  is  usually  the  implement  used  for  scratching. 


Forms  of  quartz  crystals. 


QUARTZ 
Teacher's  Story 

There  is  in  the  Cornell  University  Museum  a great  quartz  crystal,  a six- 
sided  prism  several  inches  in  thickness.  One-half  of  it  is  muddy  and  the 
other  half  clear,  transparent  and  beautiful.  The  professor  in  charge,  who 
has  the  imagination  necessary  to  the  expert  crystallographer,  said  to  his 
class:  “This  crystal  was  begun  under  conditions  which  made  it  cloudy; 

then  something  happened,  perhaps  some  cataclysm  that  changed  all  the 
conditions  around  the  half-grown  crystal,  and  it  may  have  lain  a hundred 
or  a thousand  years  unfinished,  when,  some  other  change  occurring,  there 
came  about  conditions  which  permitted  it  to  resume  growth,  and  the  work 
began  again  exactly  where  it  was  left  off,  the  shaft  being  perfected  even  to 
its  six-sided  pyramidal  tip.”  And  ever  afterwards  that  crystal,  half  clouded 
and  half  clear,  remained  in  the  minds  of  his  pupils  as  a witness  of  the  eternal 

endurance  of  the  laws  which  govern  the  growth  of  crystals.  

Quartz  is  the  least  destructible  and  is  one  of  the  most  abundant  materials 
in  the  crust  of  the  earth  as  we  know  it.  It  is  made  up  of  two  elements 
chemically  united — the  solid  silicon  and  the  gas  oxygen.  It  is  the  chief 
material  of  sand  and  sandstones,  and  it  occurs,  mixed  with  grains  of  other 
minerals,  in  granite,  gneiss,  and  many  lavas;  it  also  occurs  in  thick  masses 
or  sheets,  and  sometimes  in  crystals  ornamenting  the  walls  of  cavities  in  the 
rocks.  Subterranean  waters  often  contain  a small  amount  of  silica,  the 
substance  of  quartz,  in  solution;  from  such  solutions  it  may  be  deposited  in 


830 


Handbook  of  Nature-Study 


fissures  or  cracks  in  the  rock,  thus  forming  bodies  called  “veins.”  Other 
materials  are  often  deposited  at  the  same  time,  and  in  this  way  the  ores  of 
the  precious  metals  came  to  be  associated  with  quartz.  Sometimes  quartz 
is  deposited  from  hot  springs  or  geysers,  forming  a spongy  substance  called 
sinter.  In  this  case,  some  of  the  water  is  combined  with  the  quartz,  making 
what  is  called  opal.  Quartz  crystal  will  cut  glass. 

Quartz  occurs  in  many  varieties : (a)  In  crystals  like  glass.  If  colorless 

and  transparent  it  is  called  rock  crystal ; if  smoky  brown,  it  is  called 
smoky  quartz;  if  purple,  amethyst,  (b)  In  crystals,  glassy  but  not 
transparent.  If  white,  it  is  milky  quartz;  if  pink,  rose  quartz,  (c)  As  a 
compact  crystalline  structure  without  luster,  waxy  or  dull,  opaque  or 
translucent,  when  polished.  If  bright  red,  it  is  carnelian;  if  brownish  red, 
sard;  if  in  various  colors  in  bands,  agate;  if  in  horizontal  layers,  onyx;  if 
dull  red  or  brown,  jasper;  if  green  with  red  spots,  bloodstone;  if  smoky  or 
gray,  breaking  with  small,  shell-like  or  conchoidal  fractures,  flint. 

Rock  crystals  are  used  in  jewelry  and  especially  are  made  to  imitate 
diamonds.  The  amethyst  is  much  prized  as  a semi-precious  stone.  Car- 
nelian, bloodstone  and  agate  are  also  used  in  jewelry;  agate  is  used  also  in 
making  many  ornamental  objects,  and  to  make  little  mortars  and  pestles 
for  grinding  hard  substances. 

One  of  the  marvels  of  the  world  is  the  petrified  forest  of  Arizona,  now  set 
aside  by  the  government  as  a national  reserve.  Great  trees  have  been 
changed  to  agate  and  flint,  the  silica  being  substituted  for  the  tissues  of  the 
wood  so  that  the  texture  is  preserved  though  the  material  is  changed. 

When  our  country  was  first  settled,  flint  was  used  to  start  fires  by  strik- 
ing it  with  steel  and  letting  the  sparks  fly  into  dry,  fine  material,  called 
tinder.  It  was  also  used  in  guns  before  the  invention  of  cartridges,  and  the 
guns  were  called  flintlocks.  The  Indians  used  flint  to  make  hatchets  and 
for  tips  to  their  arrows.  The  making  of  flint  implements  dates  far  back 
into  prehistoric  times;  it  was  probably  one  of  the  first  steps  upward  which 
man  achieved  in  his  long,  hard  climb  from  a level  with  the  brute  creation 
to  the  heights  attained  by  our  present  civilization. 

Quartz  sand  is  used  in  making  glass.  It  is  melted  with  soda  or  potash  or 
lead,  and  the  glass  varies  in  hardness  according  to  the  minerals  added. 
Quartz  is  also  used  for  sandpaper  and  glass  paper;  and  ground  to  a fine 
powder,  it  is  combined  with  Japans  and  oils  and  used  as  a finish  for  wood 
surfaces.  Mineral  wool  is  made  from  the  slag  refuse  of  furnaces  where  glass 
is  made,  and  is  used  for  rat-proof  and  fireproof  padding  for  the  walls  of 
houses.  Quartz  combined  with  sodium  or  potassium  and  water,  forms  a 
liquid  called  water-glass,  which  is  used  for  waterproof  surfaces;  it  is  also 
fireproof  to  a certain  degree.  Water-glass  is  the  best  substance  in  which  to 
preserve  eggs;  one  part  of  commercial  water-glass  to  ten  parts  of  water 
makes  a proper  solution  for  this  purpose. 

LESSON  CCXIV 
Quartz 

Leading  thought — Quarts  is  one  of  the  most  common  of  minerals.  It 
occurs  in  many  forms.  As  a crystal  it  is  six-sided,  and  the  ends  terminate 
in  a six-sided  pyramid.  It  is  very  hard  and  will  scratch  and  cut  glass. 
When  broken,  it  has  a glassy  luster  and  it  does  not  break  smoothly  but 
shows  an  uneven  surface. 


Earth  Study 


831 


Method — The  pupils  should  have  before  them  as  many  varieties  of 
quartz  as  possible;  at  least  they  should  have  rock  crystal,  amethyst,  rose 
and  smoky  quartz  and  flint. 

Observations — 1.  What  is  the  shape  of  quartz  crystals?  Are  the  sides 
ail  of  the  same  size?  Has  the  pyramid-shaped  end  the  same  number  of 
plane  surfaces  as  the  sides? 

2.  What  is  the  luster  of  quartz?  Is  this  luster  the  same  in  all  the 
different  colored  kinds  of  quartz? 

3.  Can  you  scratch  quartz  with  the  point  of  a knife?  Can  you  scratch 
glass  with  a corner  or  piece  of  the  quartz  ? Can  you  cut  glass  with  quartz  ? 

4.  Describe  the  following  kinds  of  quartz  and  their  uses:  amethyst, 

agate,  flint. 

5.  How  many  varieties  of  quartz  do  you  know?  What  has  quartz  to 
do  with  the  petrified  forests  of  Arizona? 


FELDSPAR 
Teacher's  Story 

We  most  commonly  see  feldspar  as  the  pinkish  portion  of  granite.  This 
does  not  mean  that  feldspar  is  always  pink,  for  it  may  be  the  lime-soda  form 
known  as  labradorite,  which  is  dark  gray,  brown  or  greenish  brown,  or 
white ; or  it  may  be  the  soda-lime  feldspar  called  oligoclase,  which  is  grayish 
green,  grayish  white,  or  white;  but 
the  most  common  feldspar  of  all  is 
the  potash  feldspar — orthoclase — 
which  may  be  white,  nearly  trans- 
parent, or  pinkish.  Orthoclase  is 
different  from  other  feldspars  in 
that,  when  it  splits,  its  plane  sur- 
faces form  right  angles.  Feldspar 
is  next  in  the  scale  of  hardness  to  quartz,  and  will  with  effort  and  per- 
severance scratch  glass  but  will  not  cut  it;  it  can  be  scratched  with  a 
steel  point.  Its  luster  is  glassy  and  often  somewhat  pearly. 

Maine  leads  all  other  states  in  the  production  of  feldspar.  It  is  quarried 
and  crushed  and  ground  to  powder,  as  fine  as  flour,  to  make  the  clay  from 
which  china  and  all  kinds  of  pottery  are  made.  Our  clayey  soils  are  made 
chiefly  from  the  potash  feldspar  which  is  weathered  to  fine  dust.  Kaolin, 
which  has  been  used  so  extensively  in  making  the  finest  porcelain,  is  the 
purest  of  all  clays,  and  is  formed  of  weathered  feldspar;  floor  tiling  and 
sewer  pipes  are  also  made  from  ground  feldspar.  Moonstone  is  clean,  soda- 
lime  feldspar,  whitish  in  color  and  with  a reflection  something  like  an  opal. 

LESSON  CCXV 
Feldspar 

Leading  thought — Feldspar  is  about  five  times  as  common  as  quartz. 
The  crystal  is  obliquely  brick-shaped,  and  when  broken  splits  in  two  direc- 
tions at  right  angles  to  each  other.  It  is  next  in  hardness  to  quartz,  and 
will  scratch  glass  but  will  not  cut  it. 

Method — If  possible,  have  the  common  feldspar  (orthoclase),  the  soda- 
lime  feldspar  (oligoclase)  and  the  lime-soda  feldspar  (labradorite).

2.  What  colors  are  your  specimens  of  feldspar?  How  many  kinds 
have  you? 

3.  What  is  the  luster  of  feldspar?

5.  When  you  scratch  feldspar  with  steel  what  is  the  color  of  the  streak 
left  upon  it? 

6.  If  feldspar  is  broken,  does  it  break  along  certain  lines,  leaving 
smooth  faces  ? At  what  angles  do  these  smooth  faces  stand  to  each  other  ? 

7.  How  can  you  tell  feldspar  from  quartz?  Write  a comparison  of

crust,  why  is  there  so  much  more  quartz  than  feldspar  in  sand? 


MICA 

Teacher's  Story 

The  mica  crystal  when  perfect  is  a flat  crystal  with  six  straight  edges. 
These  crystals  separate  in  thin  layers  parallel  with  the  base.  In  color  mica 
varies  through  shades  of  brown,  from  a pale  smoked  pearl  to  black.  Its 
luster  is  pearly,  and  it  can  be  scratched  with  the  thumb  nail.  Its  distin- 
guishing characteristic  is  that  the  thin  layers  into  which  it  splits  bend  with- 
out breaking  and  endure  great  heat. 

Mica  was  used  in  antiquity  for  windows.  Because  it  is  transparent  and 
not  affected  by  heat,  it  is  used  in  the  doors  of  stoves  and  furnaces  and  for 
lamp  chimneys.  Its  strength  makes  it  of  use  for  automobile  goggles. 
Diamond  dust  is  powdered  mica,  as  is  also  the  artificial  snow  scattered 
over  cotton  batting  for  the  decoration  of  Christmas  trees.  When  ground 
finely,  it  is  used  as  an  absorbent  for  nitroglycerine  in  the  manufacture  of 
dynamite 

Mica  mines  are  scarce  in  this  country.  There  is  an  interesting  one  in 
North  Carolina  which  had  evidently  been  worked  centuries  before  the 
advent  of  the  white  man  in  America.  There  are  other  mica  mines  in  New 
Hampshire  and  Canada.  The  entire  production  of  this  mineral  in  the 
United  States  for  the  year  1908,  was  valued  at  a little  more  than  a quarter 
of  a million  dollars.  Nearly  all  of  this  output  was  used  in  the  electrical 
industries,  since  mica  is  one  of  the  best  insulating  materials  known. 

LESSON  CCXVI 
Mica 

Leading  thought — Mica  is  a crystal  which  flakes  off  in  thin  scales  parallel 
with  the  base  of  the  crystal.  We  rarely  see  a complete  mica  crystal  but 
simply  the  thin  plates  which  have  split  off.  The  ordinary  mica  is  light 
colored,  but  there  is  a black  form. 

Method — If  it  is  not  possible  to  obtain  a mica  crystal,  get  a thick  piece  of 
mica  which  the  pupils  may  split  off  into  layers.

Observations — 1 . Describe  your  piece  of  mica.  Pull  off  a lay  er  with  the

GRANITE 


Teacher's  Story 

In  granite,  the  quartz  may  be  detected  by  its  fracture  which  is  always 
conchoidal  and  never  flat;  that  is,  it  has  no  cleavage  planes.  It  is  usually 
white  or  smoky,  and  is  glassy  in  luster.  It  cannot  be  scratched  with  a 
knife.  The  feldspar  is 
usually  whitish  or  flesh- 
colored  and  the  smooth 
surface  of  its  cleavage 
planes  shines  brilliantly 
as  the  light  strikes  upon 
it;  it  can  be  scratched 
with  a knife  but  this 
requires  effort.  The 
mica  is  in  pearly  scales, 
sometimes  whitish  and 
sometimes  black.  The 
scales  of  these  mica 
particles  may  be  lifted 
off  with  a knife,  and  it 
may  thus  be  distin- 
guished. If  there  are 
black  particles  in  the 
granite  which  do  not 
separate,  like  the  mica, 
into  thin  layers,  they 
probably  consist  of 
hornblende. 

Granite  is  used  ex- 
tensively for  building 
purposes  and  for  monu- 
ments. It  is  a very 
durable  stone  but  in 
the  northeastern  United 
States  where  there  is

weakest,  hornblende  next,  and  feldspar  is  next  to  quartz,  the  strongest  con- 
stituent of  granite.  Water  permeates  the  mica,  hornblende,  feldspar  and 
sometimes  the  quartz,  and  by  its  expansion  in  freezing  causes  the  stone  to 
crumble.  The  reason  why  polished  granite  endures  better  than  the  rough 
finished,  is  that  the  smooth  surface  gives  less  opportunity  for  the  water  to 
lodge  and  freeze.  When  the  weathered  granite  is  cut  up  into  small 
particles  by  the  waters  of  streams,  they  are  sifted  and  all  the  parts  which 
are  soluble  are  carried  off,  leaving  a sand  composed  of  quartz  and  mica, 
which  are  insoluble.  This  sand  is  washed  by  streams  into  lakes,  and  then 
is  dropped  to  the  bottom;  if  enough  is  thus  carried  and  dropped,  it  forms 
sandstone  rock.  All  of  our  sandstones  used  for  building  purposes  were 
thus  laid  down. 

Cleopatra’s  Needle,  which  stood  for  thousands  of  years  in  the  dry 
climate  of  Egypt,  soon  commenced  to  weather  and  crumble  when  placed  in 
Central  Park,  N.  Y.  This  shaft  has  a most  interesting  history.  It  was 
quarried  near  Assuan,  in  the  most  famous  of  all  granite  quarries  of 
ancient  Egypt.  It  was  cut  as  a solid  shaft  in  the  quarry  and  carried 
down  the  Nile  River  for  500  miles — an  engineering  feat  which  would  be 
hard  to  accomplish  to-day,  with  all  our  modern  appliances.  It  was  one  of 
the  obelisks  that  graced  the  ancient  city  of  On,  later  called  Heliopolis, 
situated  on  a plateau  near  the  present  city  of  Cairo ; On  was  the  city  where 
Moses  was  born  and  reared.  There  is  still  standing  where  it  was  first 
placed  as  a part  of  a magnificent  temple,  the  temple  a part  of  a magni- 
ficent city,  one  of  these  obelisks.  It  now  stands  alone  in  the  middle  of 
a great  fertile  plain,  which  is  vividly  green  with  growing  crops ; a road 
shaded  by  tamarisk  and  lebbakh  trees  leads  to  it;  nearby  is  a sakiah, 
creaking  as  the  blindfolded  bullock  walks  around  and  around,  turning  the 
wheel  that  lifts  the  chain  of  buckets  from  the  well  to  irrigate  the  crops; 
and  a hooded  crow,  whose  ancestors  were  contemporaries  of  its  erection, 
caws  hoarsely  as  it  alights  on  the  beautiful  apex  of  this  ancient  shaft, 
which  has  stood  there  nearly  four  thousand  years  and  has  seen  a great 
city  go  down  to  dust  to  fertilize  a grassy  plain.

CALCITE,  MARBLE  AND  LIMESTONE 
Teacher's  Story 

Calc  spar,  or  calcium  carbonate,  is  a mineral  and  is  the  material  of  which 
marble,  limestone  and  chalk  are  made.  The  faces  of  the  calcite  crystal  are 
always  arranged  in  groups  of  three  or  multiples  of  three — a three-sided 
pyramid  or  two  pyramids  joined  base  to  base.  The  pyramids  may  be 
obtuse  or  acute.  When  acute  and  formed  of  three  pairs  of  faces,  the 
crystals  are  called  dog-tooth  spar.  The  crystals  appear  in  a great  variety 
of  forms,  but  they  all  have  the  common  quality  of  splitting  readily  in  three 
directions,  the  fragments  resembling  cubes 
which  are  oblique  instead  of  rectangular. 

When  these  cleaved,  or  split  pieces,  are  trans- 
parent, they  are  called  Iceland  spar.  When  an 
object  is  viewed  through  Iceland  spar  at  least 
one-quarter  inch  thick,  it  appears  double.  The 
calcite  crystal  is  often  transparent  with  a slight 
yellowish  tinge,  but  it  also  shows  other  colors; 
and  it  has  a slightly  cloudy  or  slightly  pearly  or 
almost  glassy  luster  like  feldspar.  It  is  easily 
scratched  with  a knife  and  will  not  scratch 
glass.  If  a drop  of  strong  vinegar  or  weak 
hydrochloric  acid  falls  upon  it,  it  will  effervesce. 

Limestone — so  called  because  it  is  burned  to 
make  quicklime — was  formed  on  the  bottoms 
of  oceans;  its  substance  came  chiefly  from  the 
skeletons  of  corals  and  the  shells  of  other  sea  Forms  of  calcite  crystals. 
creatures,  since  sea-shells  and  coral  stems  are 

pure  calcium  carbonate  in  composition.  In  the  water,  the  shells  and 
corals  were  broken  down,  and  then  deposited  in  layers  on  the  bottom  of  the 
sea.  So  wherever  we  find  limestone,  we  know  that  there  was  once  the 
bottom  of  a great  sea.  Such  layers  of  limestone  are  now  being  deposited  off 
the  shores  of  Florida,  where  corals  grow  in  great  abundance.  Limestone  is 
used  extensively  for  building  purposes,  and  in  most  climates  is  very  durable. 
The  great  pyramids  of  Egypt  are  of  limestone.  It  is  not  a good  material 
for  making  roads,  since  it  is  so  soft  that  it  wears  out  readily,  making  a fine 
easily-blown  dust.  It  is  slowly  dissolved  in  water,  especially  if  the  water  be 
acid;  thus,  in  limestone  regions,  there  are  caves  where  the  water  has 
dissolved  out  the  rock ; and  attached  to  their  roofs  and  piled  upon  their 
floors  may  be  large  icicle-shaped  stalactites  and  stalagmites,  which  were 
made  by  the  lime-bearing  water  dripping  down  and  evaporating,  leaving  its 
burden  in  crystals  behind  it.  When  the  roof  of  a cave  falls  in,  the  cavity 
thus  made  is  called  a sink  hole  and  is  often  dangerous.  The  famous  Natural 
Bridge  in  Virginia  is  all  that  is  left  of  what  was  once  the  roof  of  such  a 
cavern.  The  water  in  limestone  regions  is  always  hard,  because  of  the  lime 
which  it  holds  in  solution;  and  in  such  regions  the  streams  usually  have  no

silt,  but  have  clean  bottoms;  moreover,  the  springs  are  likely  to  become 
contaminated  because  the  water  has  run  through  long  caves  instead  of 
filtering  through  sand. 

Chalk  is  similar  in  origin  to  limestone;  it  is  made  up  of  the  shells  of 
minute  sea  creatures,  so  small  that  we  can  only  see  them  with  the  aid  of  a 
microscope.  Try  and  think  how  many  years  it  must  have  required  for  the 
shells  of  such  tiny  beings  to  build  up  the  beds  which  make  the  great  chalk 
cliffs  of  England! 

Marble  is  formed  inside  of  the  earth  from  limestone,  under  the  influence 
of  heat  and  pressure;  it  differs  from  limestone  chiefly  in  that  the  grains  are 
of  crystalline  structure,  and  are  larger;  it  is  usually  white  or  gray  in  color, 
and  sometimes  is  found  in  differing  colors.  At  Cadiz  in  California,  marble 
is  found  showing  twenty  or  more  quite  different  colors.  The  most  famous 
marbles  are  the  Carrara  of  Italy,  the  Parian  from  the  Island  of  Paros,  and 
the  Pentelican  from  the  mountain  of  that  name  near  Athens.  The  reason 
why  these  marbles  are  so  famous  is  that  in  ancient  times  sculptors  carved 
beautiful  statues  from  them,  and  the  architects  used  them  for  building 
magnificent  temples.  The  principal  marble  deposits  in  the  United  States 
are  in  Vermont.  Georgia,  Tennessee  and  California.  Marble  deteriorates 
when  it  is  exposed  to  air  which  is  filled  with  smoke  and  gases.  It  is  also 
used  to  make  lime.  When  either  marble  or  limestone  is  heated  very  hot,  it 
separates  into  two  parts,  one  of  which  is  lime,  and  the  other  carbonic  acid 
gas — the  same  that  is  used  for  charging  soda-water  fountains. 


LESSON  CCXVIII 
Calcite,  Marble  and  Limestone 

Leading  thought — Calcite  or  calc  spar  is  formed  more  than  half  of  lime. 
The  best  known  forms  of  its  crystals  are  cubelike,  but  instead  of  having 
twelve  right-angled  edges,  the  sides  are  lozenge-shaped,  and  are  set  together 
with  six  obtuse  angles  and  six  acute.  Dog-tooth  spar  is  one  form  of  calcite 
crystal.  Limestone  is  a solid  form  of  calcite.  Marble  is  granular  lime- 
stone which  shows  the  broken  crystals  of  calcite.  Chalk  is  very  fine, 
pulverized  calcite. 

Method — Specimens  of  dog-tooth  spar,  limestone,  marble,  shells  of 
oysters  or  other  sea  creatures  and  coral  should  be  provided  for  this  lesson; 
also  a bottle  of  dilute  hydrochloric  acid,  and  a piece  of  glass  tubing  about 
six  inches  long  with  which  to  drop  the  acid  on  the  stones.  Some  strong 
vinegar  will  do  instead  of  the  acid. 

Observations — i.  What  is  the  form  of  the  calcite  crystal  ? What  is  the 
luster  of  the  crystal  ? Is  it  the  same  as  the  inside  of  sea-shells  ? Will  calcite 
scratch  glass  ? Can  you  scratch  it  with  a knife  ? What  happens  to  calcite 
if  you  put  a drop  of  weak  hydrochloric  acid  upon  it  ? 

2.  Is  marble  made  up  of  crystals?  Examine  it  with  a lens  to  see. 
What  is  its  color?  Have  you  seen  marble  of  other  colors  than  white ? Do 
you  know  the  reason  why  marble  is  sometimes  clouded  and  streaked? 

3.  Put  a drop  of  weak  hydrochloric  acid  on  the  marble.  What  happens? 

4.  What  are  the  uses  of  marble  ? What  have  you  ever  seen  made  from 
marble?  Why  is  it  used  for  sculpture?  What  famous  statues  have  you 
seen  which  were  made  of  marble  ? N ame  some  of  the  famous  ancient  marble

5.  Test  a piece  of  limestone  for  hardness.  Can  you  scratch  it  with  a 
knife?  Is  it  as  soft  as  marble?  Put  on  it  a drop  of  acid.  Does  it  effer- 
vesce? If  there  are  any  fossils  in  your  piece  of  limestone,  test  them  with 
acid  and  see  if  they  will  effervesce.  Any  other  mineral  that  you  have  which 
will  effervesce  when  touched  with  acid,  is  probably  some  form  of  calcite. 

6.  Are  there  any  buildings  in  your  town  made  of  limestone  ? How  do 
you  know  the  stone  is  limestone?  Where  was  it  obtained?  Is  it  affected 
by  the  weather?

county  of  your  state  is  limestone  found  ?

it  happen  that  these,  which  were  once  a part  of  living  creatures,  are  now 
limestone  ? Of  what  are  our  own  bones  made  ? 


“A  great  chapter  in  the  history  of  the  world  is  written  in  the  chalk.  Few  passages  in  the 
history  of  man  can  he  supported  by  such  an  overwhelming  mass  of  direct  and  indirect  evi- 
dence as  that  which  testifies  to  the  truth  of  the  fragment  of  the  history  of  the  globe , which  I 
hope  to  enable  you  to  read , with  your  own  eyes,  to-night.  Let  me  add,  that  few  chapters  of 
human  history  have  a more  profound  significance  for  ourselves.  I weigh  my  words  well 
when  I assert,  that  the  man  who  should  know  the  true  history  of  the  bit  of  chalk  which  every 
carpenter  carries  about  in  his  breeches-pocket,  though  ignorant  of  all  other  history,  is  likely,  if 
he  will  think  his  knowledge  out  to  its  ultimate  results,  to  have  a truer,  and  therefore  a better, 
conception  of  this  wonderful  universe,  and  of  man's  relation  to  it,  than  the  most  learned 
student  who  is  deep-read  in  the  records  of  humanity  and  ignorant  of  those  of  Nature ." 

“ During  the  chalk  period,  or  1 cretaceous  epoch,'  not  one  of  the  present  great  physical 
features  of  the  globe  was  in  existence.  Our  great  mountain  ranges,  Pyrenees,  Alps , Hima- 
layas, Andes,  have  all  been  upheaved  since  the  chalk  was  deposited,  and  the  cretaceous  sea 
flowed  over  the  sites  of  Sinai  and  Ararat.  All  this  is  certain,  because  rocks  of  cretaceous 
or  still  later  date,  have  shared  in  the  elevatory  movements  which  give  rise  to  these  mountain 
chains;  and  may  be  found  perched  up,  in  some  cases,  many  thousand  feet  high  upon  their 
flanks."

THE  MAGNET 
Teacher's  Story 

NTIL  comparatively  recent  times,  the  power  of  the 
magnet  was  so  inexplicable  that  it  was  regarded  as  the 
working  of  magic.  The  tale  of  the  Great  Black  Moun- 
tain Island  magnet  described  in  the  “Arabian  Nights 
Entertainments” — the  story  of  the  island  that  pulled 
the  nails  from  passing  ships  and  thus  wrecked  them — 
was  believed  by  the  mariners  of  the  Middle  Ages.  Pro- 
fessor George  L.  Burr  assures  me  that  this  mountain 
of  lodestone  and  the  fear  which  it  inspired  were  potent  factors  in  the 
development  of  Medieval  navigation.  Even  yet,  with  all  our 
scientific  knowledge,  the  magnet  is  a mystery.  We  know  what  it 
does,  but  we  do  not  know  what  it  is.  That  a force  unseen  by  us  is 
flowing  off  the  ends  of  a bar  magnet,  the  force  flowing  from  one  end 
attracted  to  the  force  flowing  from  the  other  and  repellent  to  a force  similar 
to  itself,  we  perceive  clearly.  We  also  know  that  there  is  less  of  this  force 
at  a point  in  the  magnet  half-way  between  the  poles ; and  we  know  that  the 
force  of  the  magnet  acts  more  strongly  if  we  offer  it  more  surface  to  act 
upon,  as  is  shown  in  the  experiment  in  drawing  a needle  to  a magnet  by 
trying  to  attract  it  first  at  its  point  and  then  along  its  length.  That  this 
force  extends  out  beyond  the  ends  of  the  magnet,  the  child  likes  to  demon- 
strate by  seeing  across  how  wide  a space  the  magnet,  without  touching  the 
objects,  can  draw  to  it  iron  filings  or  tacks.  That  the  magnet  can  impart 
this  force  to  iron  objects  is  demonstrated  with  curious  interest,  as  the  child 
takes  up  a chain  of  tacks  at  the  end  of  the  magnet ; and  yet  the  tacks  when 
removed  from  the  magnet  have  no  such  power  of  cohesion.  That  some 
magnets  are  stronger  than  others  is  shown  in  the  favorite  game  of  “stealing 
tacks,  ’ ’ the  stronger  magnet  taking  them  away  from  the  weaker ; it  can  also 
be  demonstrated  by  a competition  between  magnets,  noting  how  many 
tacks  each  will  hold. 

One  of  the  most  interesting  things  about  a magnet  is  that  like  poles  repel 
and  opposite  poles  attract  each  other.  How  hard  must  we  pull  to  separate 
two  magnets  that  have  the  south  pole  of  one  against  the  north  pole  of  the 
other ! Even  more  interesting  is  the  repellent  power  of  two  similar  poles, 
which  is  shown  by  approaching  a suspended  magnetized  needle  with  a 
magnet.  These  attractive  and  repellent  forces  are  most  interestingly 
demonstrated  by  the  experiment  in  question  13  of  the  lesson.  These 
needles  floating  on  cork  join  the  magnet  or  flee  from  it,  according  to  which 
pole  is  presented  to  them. 

Not  only  does  this  power  reside  in  the  magnet,  but  it  can  be  imparted  to 
other  objects  of  iron  and  steel.  By  rubbing  one  pole  of  the  magnet  over  a 
needle  several  times,  always  in  the  same  direction,  the  needle  becomes  a 
magnet.  If  we  suspend  such  a needle  by  a bit  of  thread  from  its  center,  and 
the  needle  is  not  affected  by  the  nearness  of  a magnet,  it  will  soon  arrange 
itself  nearly  north  and  south.  It  is  well  to  thrust  the  needle  through  a cork, 
so  it  will  hang  horizontally,  and  then  suspend  the  cork  by  a thread.  The 
magnetized  needle  will  not  point  exactly  north,  for  the  magnet  poles  of  the 
earth  do  not  quite  coincide  with  the  poles  of  the  earth’s  axis. 

The  direction  assumed  by  the  magnetized  needle  may  be  explained  by 
the  fact  that  the  earth  is  a great  magnet,  but  the  south  pole  of  the  great 


Earth  Study 


839 


earth  magnet  lies  near  the  North  Pole  of  the  earth.  Thus,  a magnet  on 
the  earth’s  surface,  if  allowed  to  move  freely,  will  turn  its  north  pole 
toward  the  south  pole  of  the  great  earth  magnet.  Then,  we  might  ask, 
why  not  call  the  earth’s  magnetic  pole  that  lies  nearest  our  North  Pole  its 
north  magnetic  pole  ? That  is  merely  a matter  of  convenience  for  us.  We 
see  that  the  compass  needle  points  north  and  south,  and  the  arm  of  the 
needle  which  points  north  we  conveniently  call  its  north  pole. 

The  above  experiment  with  a suspended  needle  shows  how  the  mariner’s 
compass  is  made.  This  most  useful  instrument  is  said  to  have  been 
invented  by  the  Chinese,  at  least  1400  B.  C.,  and  perhaps  even  longer  ago. 
It  was  used  by  them  to  guide  armies  over  the  great  plains,  and  the  needle 
was  made  of  lodestone.  The  compass  was  introduced  into  Europe  about 
1300  A.  D.,  and  has  been  used  by  mariners  ever  since.  To  “box  the  com- 
pass” is  to  tell  all  the  points  on  the  compass  dial,  and  is  an  exercise  which 
the  children  will  enjoy. 

We  are  able  to  tell  the  direction  of  the  lines  of  force  flowing  from  a 
magnet,  by  placing  fine  iron  filings  on  a pane  of  glass  or  a sheet  of  paper  and 
holding  close  beneath  one  or  both  poles  of  a magnet ; instantly  the  filings 
assume  certain  lines.  If  the  two  ends  of  a horseshoe  magnet  are  used,  we 
can  see  the  direction  of  the  lines  of  force  that  flow  from  one  pole  to  the 
other. , It  is  supposed  that  these  lines  of  magnetic  force  streaming  from  the 
ends  of  the  great  earth  magnet  cause  the  Northern  Lights,  or  Aurora 
Borealis . 

Lodestone  is  a form  of  iron  with  a special  chemical  composition,  and  it  is 
a natural  magnet.  Most  interesting  stories  are  told  of  the  way  the  ancients 
discovered  this  apparently  bewitched  material,  because  it  clung  to  the  iron 
ends  of  their  staffs  or  pulled  the  iron  nails  from  their  shoes.  In  the  Ward’s 
collection  of  minerals  sent  out  to  schools,  which  costs  only  one  dollar,  there  is 
included  a piece  of  lodestone,  which  is  of  perennial  interest  to  the 
children. 

Magnets  made  from  lodestone  are  called  natural  magnets.  A bar 
magnet  or  a horseshoe  magnet  has  received  its  magnetism  from  some  other 
magnet  or  from  electrical  sources.  An  electro  magnet  is  of  soft  iron,  and  is 
only  a magnet  when  under  the  influence  of  a coil  of  wire  charged  with 
electricity.  As  soon  as  the  current  is  shut  off  the  iron  immediately  ceases 
to  be  a magnet. 

LESSON  CC&IX 
The  Magnet 

Leading  thought — Any  substance  that  will  attract  iron  is  called  a magnet, 
and  the  force  which  enables  it  to  attract  iron  is  called  magnetism.  This 
force  resides  chiefly  at  the  ends  of  magnets,  called  the  poles.  The  forces 
residing  at  the  opposite  ends  of  a magnet  act  in  opposite  directions;  in 
two  magnets  the  like  poles  repel  and  the  unlike  poles  attract  each  other. 
The  needle  of  the  mariner’s  compass  points  north  and  south,  because  the 
earth  is  a great  magnet  which  has  its  south  pole  as  a magnet  at  the  North 
Pole  of  the  world. 

Method — Cheap  toy  horseshoe  magnets  are  sufficiently  good  for  this 
lesson,  but  the  teacher  should  have  a bar  magnet,  also  a cheap  toy  compass, 
and  a specimen  of  lodestone,  which  can  be  procured  from  any  dealer  in 
minerals.  In  addition,  there  should  be  nails,  iron  filings  and  tacks  of  both 
iron  and  brass,  pins,  darning  needles  or  knitting  needles,  pens,  etc.  Each

child,  during  play  time,  should  have  a chance  to  test  the  action  of  the 
magnets  on  these  objects,  and  thus  be  able  to  answer  for  himself  the  ques- 
tions which  should  be  given  a few  at  a time. 

Observations — 1,  How  do  we  know  that  an  object  is  a magnet?  How 
many  kinds  of  magnets  do  you  know?  Of  what  substance  are  the  objects 
made  which  the  magnets  can  pick  up  ? Does  a magnet  pick  up  as  many  iron 
filings  at  its  middle  as  at  its  ends?  What  does  this  show? 

2.  How  far  away  from  a needle  must  one  end  of  the  magnet  be  before 
the  needle  leaps  toward  it?  Does  it  make  any  difference  in  this  respect,  if 
the  magnet  approaches  the  needle  toward  the  point  or  along  its  length? 
Does  this  show  that  the  magnetic  force  extends  out  beyond  the  magnet? 
Does  it  show  that  the  magnetic  force  works  more  strongly  where  it  has 
more  surface  to  act  upon? 

3.  Take  a tack  and  see  if  it  will  pick  up  iron  filings  or  another  tack. 
Place  a tack  on  one  end  of  the  magnet,  does  it  pick  up  iron  filings  now  ? 
What  do  you  think  is  the  reason  for  this  difference  in  the  powers  of  the  tack  ? 

4.  Are  some  magnets  stronger  than  others?  Will  some  magnets  pull 
the  iron  filings  off  from  others?  In  the  game  of  “stealing  tacks,”  which 
can  be  played  with  two  magnets,  does  each  end  of  the  magnet  work  equally 
well  in  pulling  the  tacks  away  from  the  other  magnet  ? 

5.  Pick  up  a tack  with  a magnet.  Hang  another  tack  to  this  one  end 
to  end.  How  many  tacks  will  it  thus  hold  ? Can  you  hang  more  tacks  to 
some  magnets  than  to  others?  Will  the  last  tack  picked  up  attract  iron 
filings  as  strongly  as  the  first  next  to  the  magnet?  Why?  Pull  off  the 
tack  which  is  next  to  the  magnet.  Do  the  other  tacks  continue  to  hold 
together?  Why?  Instead  of  placing  the  tacks  end  to  end,  pick  up  one 
tack  with  the  magnet  and  place  others  around  it.  Will  it  hold  more  tacks 
in  this  way  ? Why  ? If  a magnet  is  covered  with  iron  filings  will  it  hold  as 
many  tacks  without  dropping  the  filings? 

6.  Take  two  horseshoe  magnets  and  bring  their  ends  together.  Then 
turn  one  over  and  again  bring  the  ends  together.  Will  they  cling  to  each 
other  more  or  less  strongly  than  before?  Bring  two  ends  of  two  bar  mag- 
nets together;  do  they  hold  fast  to  each  other?  Change  ends  with  one, 
now  do  the  two  magnets  cling  more  or  less  closely  than  before?  Does  this 
show  that  the  force  in  the  two  ends  of  a magnet  is  different  in  character? 

7 . Magnetize  a knitting  needle  or  a long  sewing  needle  by  rubbing  one 
end  of  a magnet  along  its  length  twelve  times,  always  in  the  same  direction, 
and  not  back  and  forth.  Does  a needle  thus  treated  pick  up  iron  filings? 
Why? 

8.  Suspend  this  magnetized  needle  by  a thread  from  some  object 
where  it  can  swing  clear.  When  it  finally  rests  does  it  point  north  and 
south  or  east  and  west? 

9.  Bring  one  end  of  a bar  magnet  or  of  a horseshoe  magnet  near  to  the 
north  end  of  the  suspended  needle;  what  happens?  Bring  the  other  end 
of  the  magnet  near  the  north  end  of  the  needle ; what  happens  ? 

1 o . Magnetize  two  needles  so  that  their  eyes  point  in  the  same  direction 
when  they  are  suspended.  Then  bring  the  point  of  one  of  these  needles 
toward  the  eye  of  the  other,  what  happens?  Bring  the  eye  of  one  toward 
the  eye  of  the  other,  what  happens  ? When  a needle  is  thus  magnetized  the 
end  which  turns  toward  the  north  is  called  the  north  pole,  and  the  end 
pointing  south  is  called  the  south  pole. 


Earth  Study 


841 


1 1 . Try  this  same  experiment  by  thrusting  the  needles  through  the  top 
of  a cork  and  float  them  on  a pan  of  water.  Do  the  north  poles  of  these 
needles  attract  or  repel  each  other?  Do  the  south  poles  of  these  needles 
attract  or  repel  each  other  ? If  you  place  the  north  pole  of  one  needle  at 
the  south  pole  of  the  other  do  they  join  and  make  one  long  magnet  pointing 
north  and  south? 

12.  Take  a pocket  compass;  place  the  north  end  of  one  of  the  mag- 
netized needles  near  the  north  arm  of  the  compass  needle ; what  happens  ? 
Place  the  south  pole  of  the  needle  near  the  north  arm  of  the  compass  needle, 
what  happens?  Can  you  tell  by  the  action  of  your  magnet  upon  the 
compass  needle  which  end  of  your  magnet  is  the  north  pole  and  which  the 
south  pole? 

13.  Magnetize  several  long  sewing  needles  by  rubbing  some  of  them 
toward  the  eye  with  the  magnet  and  some  from  the  eye  toward  the  point. 
Take  some  small  corks,  cut  them  in  cross  sections  about  one-fourth  inch 
thick,  thrust  a needle  down  through  the  center  of  each  leaving  only  the  eye 
above  the  cork.  Then  set  them  afloat  on  a pan  of  water.  How  do  they 
act  toward  each  other?  Try  them  with  a bar  magnet  first  with  one  end 
and  then  with  the  other,  how  do  they  act? 

14.  Describe  how  the  needle  in  the  mariner’s  compass  is  used  in 
navigation. 

15.  Place  fine  iron  filings  on  a pane  of  glass  or  on  a stiff  paper.  Pass  a 
magnet  underneath;  what  forms  do  the  filings  assume?  Do  they  make  a 
picture  of  the  direction  of  the  lines  of  force  which  come  from  the  magnet? 
Describe  or  sketch  the  direction  of  these  lines  of  force,  when  the  poles  of  a 
horseshoe  magnet  are  placed  below  the  filings.  Place  two  similar  poles  of  a 
bar  magnet  beneath  the  filings ; what  form  do  they  take  now  ? 

16.  What  is  lodestone?  Why  is  it  so  called ? 

17.  What  is  the  difference  between  lodestone  and  a bar  magnet  ? What 
is  an  electro  magnet? 

18.  Write  an  English  theme  on  “The  Discovery  and  Early  Use  of  the 
Mariner’s  Compass.”

A tiller  of  the  soil. 

THE  SOIL 
Teacher's  Story 

The  soil  is  the  sepulcher  and  the  resurrection  of  all  life  in  the  past.  The  greater  the 
sepulcher  the  greater  the  resurrection.  The  greater  the  resurrection  the  greater  the  growth. 
The  life  of  yesterday  seeks  the  earth  to-day  that  new  life  may  come  from  it  tomorrow. 
The  soil  is  composed  of  stone  flour  and  organic  matter  {humus)  mixed ; the  greater  the 
store  of  organic  matter  the  greater  the  fertility. — John  Walton  Spencer. 

Because  the  child,  after  making  mud  pies,  is  told  that  his  face  is  dirty, 
he  naturally  concludes  that  all  soil  is  dirt.  But  it  is  only  when  out  of  place 
that  it  is  dirt;  for,  in  place,  it  is  the  home  of  miracles — the  matrix  from 
which  comes  that  wonderful  force  which  we  call  life.  After  the  study  of 
the  brook,  the  crystals,  the  minerals  and  the  rocks,  the  pupils  are  ready  for 
a more  careful  study  of  the  soil.  However,  most  of  the  study  in  soils 
belongs  to  agriculture  rather  than  to  nature-study. 

The  Soil  Makers 

If  we  could  go  back  to  the  very  beginning,  we  should  find  that  the  soil 
consisted  solely  of  broken  off  particles  of  rock — particles  so  finely  ground 
by  nature’s  forces  that  we  might  properly  call  them  “rock  flour.”  In  our 
study  of  the  brook,  we  noted  that  those  stones  with  sharp  corners  were  just 
beginning  their  experience  in  the  brook  mill,  and  those  that  were 
rounded  out,  forming  pebbles,  had  their  corners  ground  off  in  the  making 
of  the  soil  grist.  And  in  the  work  of  the  brook  we  saw  how  this  grind- 
ing was  done,  and  how  the  soil  grist  is  sifted,  sorted,  carried  and 
dropped. 


Earth  Study 


843 


But  there  are  other  agencies  besides 
water  that  help  in  grinding  the  stone  flour. 

If  we  visit  some  rocky  cliff,  we  are  sure  to 
find  at  its  base  a heap  of  stones,  gravel  and 
soil,  which  the  geologists  call  talus.  In  our 
eastern  country  we  know  that  these  pebbles 
and  soil  were  pried  loose  by  Jack  Frost 
with  his  ice  wedges.  The  water  filters  into 
all  the  cracks  and  crevices  of  the  rock,  and 
since  water,  when  freezing,  is  obliged  to 
expand,  the  particles  of  rock  were  thereby 
torn  loose  and  forced  off  and  fell  to  the 
bottom  of  the  cliff.  Moreover,  rocks 
expand  when  hot,  and  are  often  thus 
broken  without  the  aid  of  water  and  frost . 

In  the  rocks  of  the  desert,  the  changes  in 
temperature  pry  off  the  rock  particles, 
which  the  winds  carry  away  to  make  up 
the  sands  of  the  desert.  The  winds  hurl 
these  sands  against  other  rocks  which  are 
still  standing,  and  hurl  them  with  such  force 
that  more  particles  are  torn  off,  making 
more  sand.  In  fact,  the  _ wind,  in  some  Qne  of  Uncle  John's  nieces  making 
regions,  grinds  the  rocks  into  stone  flour  stone  flour. 

as  effectually  as  does  the  water  in  other 

places.  Then,  too,  the  gases  of  the  air  also  cause  rocks  to  decay.  We 
know  how  iron  rusts  and  falls  to  pieces  through  contact  with  the  gases 
of  the  air.  Some  rocks  decompose  in  a similar  way.  We  often  see  that 
the  inscriptions  on  old  headstones  have  been  almost  obliterated,  because 
the  gases  in  the  air  have  so  decomposed  the  marble. 

In  addition  to  the  other  soil  makers,  there  are  the  little  plants  which  we 
call  lichens.  The  spores  of  these  plants  are  so  minute  that  we  cannot  see 
them,  and  they  drift  about  in  the  air  until  they  find  resting  place  upon  some 
rock.  Here  they  begin  to  grow,  and  as  they  grow  they  become  strongly 
acid ; they  are  thus  enabled  to  eat  a foothold  into  the  rock,  softening  its

surface  and  powdering  it  into  stone  flour.  And  in  these  situations  other 
plants  grow  later,  sending  their  roots  down  into  every  crack  and  orevice 
and  thus  prying  off  more  of  the  rock. 

The  Soil  Carriers 

In  the  study  of  the  brook  we  have  seen  how  the  water  lifts,  carries  and 
deposits  the  soils ; and  since,  at  one  time  or  another,  the  entire  surface  of 
the  earth  has  been  under  water,  we  can  see  that  water  has  been  the  most 
important  of  the  soil  carriers  and  has  done  the  greatest  work.  The  wind 
carries  much  soil,  especially  in  the  arid  regions ; the  movements  of  the  sand 
dunes  in  the  deserts  and  on  the  seashores  bear  witness  to  what  the  wind  can 
do  as  a soil  carrier.  But  in  the  northern  United  States,  from  New  England 
to  the  Dakotas,  much  of  our  soil  has  been  carried  by  a great  ice  river  that 
once  upon  a time  flowed  down  upon  our  lands  from  the  North.  This  great, 
slow-moving  river,  perhaps  a mile  or  more  high,  plowed  up  the  soil  and 
stones,  and  freezing  them  fast  carried  and  shoved  them  along  under  its 
great  weight.  After  a time  the  ice  melted  and  dropped  its  burden.  Many 
of  the  stones  were  of  granite  taken  up  from  the  old  mountains  of  northern 
Canada  and  ground  off  and  rounded  during  their  journey.  We  call  these 
stones  which  were  brought  down  to  us  from  the  North,  “boulders and  the 
soils  which  were  brought  along  on  the  bottoms  of  glaciers  and  dropped  and 
pressed  down  by  the  tremendous  ice  weight  and  thus  made  compact 
although  unsorted,  we  call  “hardpan.” 


The  Kinds  of  Soil 

By  the  work  of  these  soil  makers  and  soil  carriers,  the  rock  flour  was 
made.  But  if  we  should  take  some  of  it  and  plant  our  seeds  in  it,  we  should 
find  that  they  would  not  grow  thriftily,  even  though  we  watered  them  and 
gave  them  every  care.  The  reason  for  this  is  that  most  rock  flour  does  not 
have  in  it  the  substances  which  the  plants  most  need  for  their  growth.  But 
if  we  should  go  to  the  woods  and  get  some  of  the  black  woods-earth  and  mix 
it  with  rock  flour,  we  should  find  that  our  plants  would  thrive.  This  rich, 
earth  mold  in  the  forest  is  almost  wholly  made  up  of  matter  once  alive,  but 
which  is  now  decayed,  and  which  we  call  “humus.”  The  more  humus  that 
we  have  in  the  rock  flour,  the  richer  it  is  in  plant  food,  and  the  more  plant 
growth  it  will  support. 

In  general,  soils  may  be  divided  into  clay,  sand,  gravel,  loam  and 
humus. 

Clay  in  its  purest  sftate  is  kaolinite,  the  result  of  weathering  of  feldspar, 
or  mica.  It  is  finely  powdered  a,nd  is  used  for  pottery,  while  the  less  pure 
clays  are  used  for  brickmaking.  Clayey  soil  is  sticky  and  slippery  when 
wet,  and  bakes  hard  and  cracks  when  dry.  It  is  hard  to  cultivate,  but  it 
absorbs  moisture  from  the  air  and  holds  fast  to  its  fertility,  and  is  especially 
good  for  permanent  pastures  and  meadows. 

Sand,  in  a pure  state,  is  made  up  mostly  of  finely  broken  particles  of 
quartz  and  feldspar,  and  is  used  for  the  making  of  glass.  A sandy  soil  is 
light  and  open  and  easy  to  work.  It  absorbs  little  water  from  the  air  and 
has  little  power  for  holding  plant  food,  since  the  water  washes  it  out.  It  is 
especially  valuable  for  truck  gardening,  because  it  is  a warm  soil.  It  is 
warm  because  water  does  not  evaporate  from  its  surface  rapidly.

Humus  is  composed  of  decayed  animal  and  vegetable  matter.  It  is  very 
rich  in  plant  food.  Wherever  there  is  humus  in  the  soil  it  is  likely  to  be 
darker  in  color  than  the  stone  flour. 

Loam  is  a mixture  of  clay,  sand  and  humus.  For  many  crops  it  is  the 
most  desirable  soil. 

LESSON  CCXX 

The  Soil 

Leading  thought — The  soil  is  composed  of  rock  flour  and  humus.  Soil, 
to  support  life,  must  be  porous,  so  that  the  roots  of  the  plants  may  receive 
through  it  both  water  and  air. 

Method — The  children  should  bring  in  specimens  of  soils  from  various 
localities  near  the  school.  Parts  of  each  specimen  should  be  wet  to  see  if 
they  are  clayey,  that  quality  showing  quickly  in  the  puttylike  adhesiveness 
when  rubbed  between  the  fingers.  It  would  be  well  to  get  some  pure  blue 
day,  and  let  the  children  make  marbles  of  it  to  impress  upon  them  this 
quality  of  clay.  They  should  try  and  make  marbles  of  other  soils  to  show 
the  lack  of  adhesiveness  in  them.  They  should  examine  sand  through  a 
lens  and  should  examine  humus  in  a similar  way.  After  they  are  familiar 
with  these  three  kinds  of  soils,  they  are  ready  for  the  lesson. 

Observations — 1 . Look  at  any  kind  of  soil  with  a lens,  and  tell  why  you 
think  it  is  made  up  of  small  pieces  of  stone  and  rock. 

2.  Take  a piece  of  rock  and  pound  it  fine.  What  does  it  look  like? 
Do  you  think  that  your  plants  will  grow  well  if  you  plant  them  in  the  rock 
flour  which  you  have  just  made?  Try  the  experiment  and  describe  the 
results. 

3 . How  does  the  water  grind  off  the  stones  and  make  soil  ? How  does 
the  wind  do  it? 

4.  How  do  water  and  frost  pry  off  pieces  of  rock.  Is  there  a cliff  in 
your  neighborhood  that  has  at  its  foot  a heap  of  soil  and  stones?  Where 
did  these  comes  from? 

5.  How  do  the  lichens  and  other  plants  pry  off  the  outside  of  rocks? 
Have  you  ever  found  lichens  growing  on  stones? 

6.  Have  you  ever  noticed  old  headstones  in  the  cemetery  that  were 
falling  to  pieces  ? What  causes  them  to  decay  ? 

7.  Write  an  English  theme  on  the  great  glacier  that  formerly  covered 
the  northeastern  portion  of  the  United  States. 

8 . Go  to  the  woods,  scrape  off  the  leaves  and  get  some  of  the  black  earth 
beneath  them.  Of  what  is  this  soil  composed?  Is  it  rock  flour?  What 
makes  it  so  black  ? Why  do  you  call  this  soil  rich  ? What  does  it  do  if  you 
add  it  to  the  soil  in  the  pots  where  your  flowers  are  growing? 

9.  Find  a railroad  cut  or  some  other  place  where  the  earth  is  exposed 
for  some  distance  up  and  down.  Is  there  solid  rock  at  the  bottom?  How 
deep  is  the  soil  above  the  rock  ? Is  the  soil  the  same  color  at  the  surface  as 
it  is  below?  Why  is  this? 

10.  Experiment  1:  To  show  which  kinds  of  soil  hold  most  water— Take 

three  lamp  chimneys,  or  bottles  from  which  the  bottoms  have  been  broken. 
Place  in  one  loam  in  another  clay,  in  another  fine-grained  sand,  using  in 
each  case  the  same  amount.  Tie  cheesecloth  over  the  bottom,  so  that  the 
soil  will  not  fall  out;  make  the  soil  compact  by  jarring  down.  Place  each 
over  a tumbler.  From  a cup  of  water,  held  as  near  as  possible  to  the  soil, 
pour  water  into  one  of  the  bottles  slowly,  so  as  to  keep  the  surface  of  the  soil 


846 


Handbook  of  Nature-Study 


covered.  Consult  a watch  and  note  how  long  before  the  water  begins 
dripping  below.  Do  the  same  with  the  other  two.  Compare  the  results. 
Which  soil  takes  the  water  most  rapidly?  Which  lets  it  through  first  ? 
Which  lets  through  the  most  ? How  would  rain  affect  fields  of  clayey  soil  ? 
Of  sandy  soil  ? Of  loam  ? 

Hints  for  teacher  on  Experiment  No.  i — Through  sand  the  water  passes 
very  rapidly — in  less  than  a minute  if  the  sand  is  coarse.  It  takes  several 
minutes  (14  min.)  to  go  through  loam,  but  requires  some  hours  to  appear 
below  the  clay.  It  requires  more  water  to  saturate  clay.  Care  should  be 
taken  to  use  the  same  amount  of  water  on  the  three  kinds  of  soil.  More 
than  one  application  will  be  required  for  clay,  since  the  amount  of  water 


Loam.  Sand.  Clay. 

Note  that  the  sand  has  allowed  the  most  water  to  drip  through  it,  the  loam  next, 
while  no  water  has  passed  through  the  clay. 


accommodated  in  the  chimney  above  the  soil  will  not  be  sufficient  to  satu- 
rate clay. 

More  water  will  be  found  to  have  percolated  through  sand  than  through 
loam  or  clay.  The  latter  are  more  retentive  of  moisture  than  is  sand, 
although  absorbing  rain  less  readily  than  sand.  The  mixture  of  sand  and 
clay  in  loam  is  most  ideal  for  cultivated  fields,  absorbing  moisture  more 
readily  than  clay  and  retaining  it  better  than  sand. 

Experiment  2 — Fill  a glass  tumbler  with  very  small  marbles  or  buckshot. 
Pour  water  over  them  to  fill  the  glass.  Placing  cheesecloth  over  the  top  of 
the  tumbler  pour  off  all  the  water  that  easily  drains  away.  Remove  the 
cheesecloth,  and  immediately  examine  the  marbles  for  the  film  of  water 
which  surrounds  each  one  and  can  clearly  be  seen  where  one  marble  comes  in 
contact  with  another  marble  or  the  side  of  the  glass. 

Hints  for  teacher  on  Experiment  2 — It  is  sucn  a film  of  water  as  remains 
on  the  marbles  that  on  each  particle  of  soil  supplies  the  plant  with  water  and

corresponds  to  that  carried  out  of  the  soil  by  drainage;  it  is  injurious  to  the 
plant,  keeping  “its  feet  too  wet,”  and  should  be  removed.

Experiment  3 — To  show  that  soil  lifts  water  up  from  below — Use  the  same 
soils  arranged  in  the  same  way  as  for  Experiment  1 , but  instead  of  pouring 
water  in  at  the  top,  place  the  three  lamp  chimneys  in  a pan  which  has  water 
in  it  about  an  inch  deep.  In  which 
soil  does  the  water  rise  most  rapidly  ? 

In  which  does  it  rise  the  highest? 

After  the  water  has  been  taken  up, 
let  the  soil  stand  in  the  lamp 
chimneys  for  several  days.  Which 
soil  dries  out  the  soonest?  If  we 
had  three  fields,  one  of  loam,  one  of 
clay,  and  one  of  sand,  in  which 
would  the  most  water  be  lifted  from 
below  for  the  use  of  the  plants? 

Which  would  retain  the  water 
longest  ?

short  time;  if  rather  fine  sand  is  used  Sand.  Clay.  Loam. 

it  requires  less  than  half  an  hour.  The  water  has  nearly  reached  the  upper  surface

three  or  four  times  as  long,  and  may  clay  u has  climbed  but  a short  distance- 
not  reach  the  top  of  the  clay  for 

several  days.  If  the  glass  tubes  were  three  or  four  feet  long  and  allowed 
to  stand  for  several  days,  we  would  find  that  although  the  water  climbs 
very  slowly  through  the  clay  it  will  climb  to  a greater  height  in  clay  than 

in  loam  or  sand.  Under  field 
conditions  clay  will  retain 
moisture  for  a longer  time 
than  sand  or  loam. 

Experiment  4 — To  show 
that  mulch  keeps  the  water  from 
evaporating  from  soils — Take 
two  of  the  lamp  chimneys 
filled  half  full  with  loam. 
Pour  in  the  same  amount  of 
water  in  each  until  the  soil  is 
thoroughly  wet.  Cover  the 
top  of  one  with  an  inch  deep 
of  dry,  loose  earth.  Which 
dries  out  first?  What  does 
the  loosening  and  pulverizing 
of  the  soil  in  our  fields  by 
harrowing  do  for  our  planted 
crops?  What  is  a mulch? 

Hints  for  teacher  on  Experi- 
ment 4 — The  soil  covered 
with  a layer  of  dry  soil — 
a dust  mulch  — will  retain 
moisture  much  longer  than 
the  unmulched  soil.  Hence, 
the  farmer  or  gardener  loosens 


The  unmulched  loam  in  the  chimney  at  the  left 
dried  out  in  four  days.  The  loam  covered  with  a

and  pulverizes  the  top  soil  by  harrowing,  hoeing  or  raking  in  order  to 
retain  moisture  for  plant  roots.  A mulch  may  also  be  of  straw,  boards, 
leaves  or  stones.  Fallen  leaves  form  a natural  mulch  in  the  woods. 
There,  at  any  time,  under  this  covering,  may  be  found  moist  earth.  A 
mulch  is  a soil  cover  which  breaks  the  capillary  connection,  so  that  water 
will  not  rise  to  the  surface  to  be  evaporated.  To  be  efficient  a mulch 
must  be  dry.  After  rain  the  “dust  blanket”  on  the  garden  bed  should  be 
renewed  by  cultivation. 

Experiment  5 — Fill  several  vials  with  different  soils  from  fields  in  the 
neighborhood.  If  the  soil  in  any  of  the  vials  is  dry,  moisten  it.  Take 
a piece  of  blue  litmus  paper  and  press  down  into  the  soil  in  each  vial.  Does 
the  litmus  paper  turn  red  as  it  becomes  dampened  by  the  soil  in  any 
of  the  vials?  If  so,  this  soil  is  acid.  Add  a little  lime  and  mix  it  in 
thoroughly  with  the  soil  m the  vial  that  shows  the  acid  soil.  Test  it  again 
with  the  litmus  paper.  Does  the  paper  remain  blue  or  turn  red?  Does 
alfalfa  and  clover  grow  on  acid  soils?  Why  should  we  add  lime  to  such 
soils  ? 

Hints  for  teacher  on  Experiment  5 — A slightly  acid  soil  may  show  no 
reaction  with  litmus  paper.  It  may  be  well  to  have  a prepared  soil  wnh  a 
few  drops  of  vinegar  or  other  acid  added,  which  will  show  the  reaction. 
The  addition  of  lime  will  correct  the  acid  condition.  Soils  for  alfalfa  or

clover  should  never  be  acid.  They  are  usually  well  limed  before  an 
attempt  is  made  to  grow  these  legumes. 

Experiment  6,  which  indicates  the  proper  treatment  of  clay  soils — Fill  four 
pie  tins  with  clay  which  has  been  wet  and  smoothly  puddled.  In  one  mix 
with  the  clay  a small  portion  of  lime;  in  another  add  a larger  portion  of 
muck;  leave  two  with  pure  clay,  and  place  one  of  these  out-of-doors  where 
it  will  freeze  hard.  Then  place  the  four  tins  on  a shelf  and  allow  to  dry. 
In  which  of  these  is  the  clay  most  friable  ? In  which  is  it  the  hardest  ? 

Hints  to  the  teacher  on  Experiment  6 — This  experiment  shows  that  freez- 
ing the  clay  rendered  it  finer,  so  that  it  may  be  broken  easily  into  particles 
small  enough  to  set  closely  about  the  plant’s  roots.  The  clay  mixed  with 
lime  is  much  more  friable  than  the  one  mixed  with  muck,  showing  that  clay 
needs  lime  more  than  organic  matter  to  make  it  of  greatest  use.  The  pure 
clay  which  is  dried  without  freezing  hardens  into  large,  flat  pieces,,  each 
being  almost  as  hard  as  stone.

WATER  FORMS 
Teacher's  Story 

Water,  in  its  various  changing  forms,  is  an  example  of  another  over- 
worked miracle — so  common  that  we  fail  to  see  the  miraculous  in  it.  We 
cultivate  the  imagination  of  our  children  by  tales  of  the  Prince  who 
became  invisible  when  he  put  on  his  cap  of  darkness,  and  who  made  far 
journeys  through  the  air  on  his  magic  carpet.  And  yet  no  cap  of  darkness 
ever  wrought  more  astonishing  disappearances  than  occur  when  this  most 
common  of  our  earth’s  elements  disappears  from  under  our  very  eyes,  dis- 
solving into  thin  air.  We  cloak  the  miracle  by  saying  ‘ ‘water  evaporates,  ’ ’ 
but  think  once  of  the  travels  of  one  of  these  drops  of  water  in  its  invisible 
cap!  It  may  be  a drop  caught  and  clogged  in  a towel  hung  on  the  line 
after  washing,  but  as  soon  as  it  dons  its  magic  cap,  it  flies  off  in  the  atmos- 
phere invisible  to  our  eyes ; and  the  next  time  any  of  its  parts  are  evident  to 
our  senses,  they  may  occur  as  a portion  of  the  white  masses  of  cloud  sailing 
across  the  blue  sky,  the  cloud  which  Shelley  impersonates: 

“I  am  the  daughter  of  Earth  and  Water, 

And  the  nursling  of  the  Sky; 

I pass  through  the  pores  of  the  ocean  and  shores; 

I change,  but  I cannot  die.” 

We  have,  however,  learned  the  mysterious  key-word  which  brings  back 
the  vapor  spirit  to  our  sight  and  touch.  This  word  is  “cold.”  For  if  our 
drop  of  water,  in  its  cap  of  darkness,  meets  in  its  travels  an  object  which  is 


Earth  Study 


851 

cold,  straightway  the  cap  falls  off  and  it  becomes  visible.  If  it  be  a stratum 
of  cold  air  that  meets  the  invisible  wanderer,  it  becomes  visible  as  a cloud, 
or  as  mist,  or  as  rain.  If  the  cold  object  be  an  ice  pitcher,  then  it  appears  as 
drops  on  its  surface,  captured  from  the  air  and  chained  as  ‘'flowing  tears" 
upon  its  cold  surface.  And  again,  if  it  be  the  cooling  surface  of  thA  earth  at 
night  that  captures*  the  wanderer,  it  appears  as  dew. 

But  the  story  of  the  water  magic  is  only  half  told.  The  cold  brings  back 
the  invisible  water  vapor,  forming  it  into  visible  drops;  but  if  it  is  cold 
enough  to  freeze,  then  we  behold  another  miracle,  for  the  drops  are  changed 
to  crystals.  The  cool  window-pane  at  evening  may  be  dimmed  with  mist 
caught  from  the  air  of  the  room ; if  we  examine  the  mist  with  a lens  we  find 
it  composed  of  tiny  drops  of  water.  But  if  the  night  be  very  cold,  we  find 
next  morning  upon  the  window-pane  exquisite  ferns,  or  stars,  or  trees,  all 
formed  of  the  crystals  grown  from  the  mist  which  was  there  the  night  before. 
Moreover,  the  drops  of  mist  have  been  drawn  together  by  crystal  magic, 
leaving  portions  of  the  glass  dry  and  clear. 

If  we  examine  the  grass  during  a cool  evening  of  October  we  find  it 
pearled  with  dew,  wrung  from  the  atmosphere  by  the  permeating  coolness 
of  the  surface  of  the  ground.  If  the  following  night  be  freezing  cold,  the 
next  morning  we  find  the  grass  blades  covered  with  the  beautiful  crystals  of 
hoar  frost. 

If  a raincloud  encounters  a stratum  of  air  cold  enough  to  freeze,  then 
what  would  have  been  rain  or  mist  comes  down  to  us  as  sleet,  hail  or  snow- 
flakes, and  of  all  the  forms  of  water  crystals,  that  of  snow  in  its  perfection  is 
the  most  beautiful ; it  is,  indeed,  the  most  beautiful  of  all  crystals  that  we 
know.  Why  should  water  freezing  freely  in  the  air  so  demonstrate  geome- 
try by  forming,  as  it  does,  a star  with  six  rays,  each  set  to  another,  at  an 
angle  of  60  degrees?  And  as  if  to  prove  geometry  divine  beyond  cavil, 
sometimes  the  rays  are  only  three  in  number — a factor  of  six — and  include 
angles  of  twice  60  degrees.  Moreover,  the  rays  are  decorated,  making 
thousands  of  intricate  and  beautiful  forms;  but  if  one  ray  of  the  six  is 
ornamented  with  additional  crystals  the 
other  five  are  decorated  likewise.  Those 
snow  crystals  formed  in  the  higher 
clouds  and,  therefore,  in  cooler  regions 
may  be  more  solid  in  form,  the  spaces  in 
the  angles  being  built  out  to  the  tips  of 
the  rays  including  air  spaces  set  in  sym- 
metrical patterns:  and  some  of  the 

crystals  may  be  columnar  in  form,  the 
column  being  six-sided.  While  those 
snow  crystals  formed  in  the  lower  cur- 
rents of  air,  and  therefore  in  warmer 
regions,  show  their  six  rays  marvellously 
ornamented.  The  reason  why  the  snow 
crystals  are  so  much  more  beautiful  and 
perfect  than  the  crystals  of  hoar  frost  or 
ice,  is  because  they  are  formed  from  water 
vapor,  and  grow  freely  in  the  regions  of 
the  upper  air.  Mr.  W.  A.  Bentley,  who  has  spent  many  years  photo- 
graphing the  snow  crystals,  has  found  more  than  1300  distinct  types.

The  high  clouds  are  composed  of 
ice  crystals  formed  from  the  cloud  mists; 
such  ice  clouds  form  a halo  when  veiling 
the  sun  or  the  moon. 

When  the  water  changes  to  vapor  and 
is  absorbed  into  the  atmosphere,  we  call 
the  process  evaporation.  The  water 
left  in  an  open  saucer  will  evaporate  more 
rapidly  than  that  in  a covered  saucer, 
because  it  comes  in  contact  with  more 
air.  The  clothes  which  are  hung  on  the 
line  wet,  dry  more  rapidly  if  the  air  is  dry 
and  not  damp;  for  if  the  air  is  damp,  it 
means  that  it  already  has  almost  as  much 
water  in  it  as  it  can  hold.  The  clothes 
will  dry  more  rapidly  when  the  air  is  hot, 
because  hot  air  takes  up  moisture  more 
readily  and  holds  more  of  it  than  does 
cold  air.  The  clothes  will  dry  more 
rapidly  on  a windy  day,  because  more  air 
moves  over  them  and  comes  in  contact 
with  them  than  on  a still  day. 

If  we  observe  a boiling  teakettle,  we 
can  see  a clear  space  of  perhaps  an  inch 
or  less  in  front  of  the  spout.  This  space 
is  filled  with  steam,  which  is  hot  air 
saturated  with  hot  water  vapor.  But 
what  we  call  “steam”  from  a kettle,  is 
this  same  water  vapor  condensed  back 
into  thin  drops  of  water  or  mist  by 
coming  into  contact  with  the  cooler  air  Blizzard  type  of  snow  crystal  formed 
of  the  room.  When  the  atmosphere  is  in  low  cloud. 

dry,  water  will  boil  away  much  more  Photomicrograph  by  W.  A.  Bentley, 
rapidly  than  when  the  air  is  damp. 

The  breath  of  a horse,  or  our  own  breath,  is  invisible  during  a warm  day; 
but  during  a cold  day,  it  is  condensed  to  mist  as  soon  as  it  is  expelled  from 
the  nostrils  and  comes  in  contact  with  the  cold  air.  The  one  who  wears 
spectacles  finds  them  unclouded  during  warm  days;  but  in  winter  the 
glasses  become  cold  out  of  doors,  and  as  soon  as  they  are  brought  into  con- 
tact with  the  warmer,  damp  atmosphere  of  a room,  they  are  covered 
with  a mist.  In  a like  manner,  the  window-pane  in  winter,  cooled  by 
the  outside  temperature,  condenses  on  its  inner  surface  the  mist  from  the 
damp  air  of  the  room. 

The  water  vapor  in  the  atmosphere  is  invisible,  and  it  moves  with  the 
air  currents  until  it  is  wrung  out  by  coming  into  contact  with  the  cold. 
The  air  thus  filled  with  water  vapor  may  be  entirely  clear  near  the  surface 
of  the  earth;  but,  as  it  rises,  it  comes  in  contact  with  cooler  air  and  dis- 
charges its  vapor  in  the  form  of  mist,  which  we  call  clouds;  and  if  there  is 
enough  vapor  in  the  air  when  it  meets  a cold  current,  it  is  discharged  as  rain 
and  falls  back  to  the  earth.  Thus,  when  it  is  very  cloudy,  we  think  it  will 
rain,  because  clouds  consist  of  mist  or  fog;  and  if  they  are  subjected  to  a 
colder  temperature,  the  mist  is  condensed  to  rain.  Thus,  often  in  moun-

tainous  regions,  the  fog  may  be  seen  streaming  and  boiling  over  a mountain 
peak,  and  yet  always  disappears  at  a cer- 
tain distance  below  it.  This  is  because  the 
temperature  around  the  peak  is  cold  and 
condenses  the  water  vapor  as  fast  as  the 
wind  bringsit  along,  but  the  mist  passes  over 
and  soon  meets  a warm  current  below  and, 
presto,  it  disappears!  It  is  then  taken 
back  into  the  atmosphere.  The  level  base 
of  a cumulus  cloud  has  a stratum  of  warmer 
air  below  it,  and  marks  the  level  of  con- 
densation. 

At  the  end  of  the  day,  the  surface  of  the 
ground  cools  more  quickly  than  the  air 
above  it.  If  it  becomes  sufficiently  cold 
and  the  air  is  damp,  then  the  water  from  it 
is  condensed  and  dew  is  formed  during  the 
night.  However,  all  dew  is  not  always 
condensed  from  the  atmosphere,  since  some 
of  it  is  moisture  pumped  up  by  the  plants, 
which  could  not  evaporate  in  the  cold  night 
air.  On  windy  nights,  the  stratum  of  air 
cooled  by  the  surface  of  the  earth  is  moved 
along  and  more  air  takes  its  place,  and  it 
therefore  does  not  become  cold  enough  to 
be  obliged  to  yield  up  its  water  vapor  as 
dew.  If  the  weather  during  a dewy  night 
becomes  very  cold,  the  dew  becomes 
crystallized  into  hoar  frost.  The  crystals 
of  hoar  frost  are  often  very  beautiful  and 
are  well  worth  our  study. 

The  ice  on  the  surface  of  a still  pond 
begins  to  form  usually  around  the  edges 
first,  and  fine,  lancelike  needles  of  ice  are 
sent  out  across  the  surface.  It  is  a very 
interesting  experience  to  watch  the  ice 
crystals  form  on  a shallow  pond  of  water. 

This  may  easily  be  seen  during  cold  winter 
weather.  It  is  equally  interesting  to 
watch  the  formation  of  the  ice  crystals  in  a 
glass  bottle  or  jar.  Water,  in  crystallizing,  Dew  on  spider's  web;  Dewdrops  on

often  presses  so  hard  against  the  sides  of  the  bottle  as  to  break  it.  The  ice 
in  the  surface  soil  of  the  wheat  fields  expands  and  buckles,  holding  fast  in 
its  grip  the  leaves  of  the  young  wheat  and  tearing  them  loose  from  their 
roots;  this  “heaving”  is  one  cause  for  the  winter-killing  of  wheat.  Sleet 
consists  of  rain  crystallized  in  the  form  of  sharp  needles.  Hail  consists  of 
ice  and  snow  compacted  together,  making  the  hard,  more  or  less  globular 
hailstones.

LESSON  CCXXI 

Water  Forms 

Leading  thought — W ater  occurs 
as  an  invisibl^Vapor  in  the  air 
and  also  as  mist  and  rain;  and 
when  subjected  to  freezing,  it 
crystallizes  into  ice  and  frost  and 
snow. 

Method — The  answers  to  the 
questions  of  this  lesson  should,  as 
far  as  possible,  be  given  in  the 
form  of  a demonstration.  All  of 
the  experiments  suggested  should 
be  tried,  and  the  pupils  should 
think  the  matter  out  for  them- 
selves. In  the  study  of  the  snow 
crystals  a compound  microscope 
is  a great  help,  but  a hand  lens 
will  do.  This  part  of  the  work 
must  be  done  out  of  doors.  The 
most  advantageous  time  for 
studying  the  perfect  snow  cry- 
stals is  when  the  snow  is  falling  in 
small,  hard  flakes;  since,  when 
the  snow  is  soft,  there  are  many 
crystals  massed  together  into 
great  fleecy  flakes,  and  they  have 
lost  their  original  form.  The 
lessons  on  frost  or  dew  may  be 
given  best  in  the  autumn  or 
spring. 

Observations — i.  Place  a saucer 
filled  with  water  near  a stove  or 
radiator;  do  not  cover  it  nor 
disturb  it.  Place  another  saucer 
filled  with  water  near  this  but 
cover  it  with  a tight  box.  From 
which  saucer  does  the  water 
evaporate  most  rapidly?  Why? 

2 . We  hang  the  clothes,  after 
they  are  washed,  out  of  doors  to 
dry;  what  becomes  of  the  water 
that  was  in  them?  Will  they 
dry  more  rapidly  during  a clear 
or  during  a damp  day?  Why? 
Will  they  dry  more  rapidly  dur- 
ing a still  or  during  a windy  day? 
Why?  Will  they  dry  more 
rapidly  during  hot  or  cold 
weather?  Why? 

3.  Watch  a teakettle  of 


855 


Earth  Study 

water  as  it  is  boiling.  Notice  that  near  its  spout  there  is  no  mist,  but  what 
we  call  steam  is  formed  beyond  this.  Why  is  this  so?  What  is  steam? 
Why  does  water  boil  away  ? Do  kettles  boil  dry  sooner  on  some  days  than 
on  others?  Whv^? 

4.  If  the  water  disappears  in  the  atmosphere  where  does  it  go?  Why 
do  we  say  “the  weather  is  damp”  ? What  force  is  it  that  wrings  the  water

do  the  window-panes  become  covered  with  mist  during  cold  weather?  Is 
the  mist  on  the  outside  or  on  the  inside  ? Why  does  steam  show  as  a white 
mist?  Why  does  the  ice  pitcher,  on  a warm  day,  become  covered  on  the 
outside  with  drops  of  water?  Would  this  happen  on  a cold  day?  Why  not? 

6.  Why,  when  the  water  is  invisible  in  the  atmosphere,  does  it  become 
visible  as  clouds?  What  causes  the  lower  edges  of  cumulus  clouds  to  be 
so  level?  What  is  fog?  Why  do  clouds  occur  on  mountain  peaks? 
What  causes  rain? 

7.  What  causes  dew  to  form?  When  the  grass  is  covered  with 
dew,  are  the  leaves  of  the  higher  trees  likewise  covered?  Why  not? 
What  kind  of  weather  must  we  have  in  order  to  have  dewy  nights?  What 
must  be  the  atmosphere  of  the  air  in  relation  to  that  of  the  ground  in 
order  to  condense  the  dew  ? Does  dew  form  on  windy  nights  ? Why 
not?  Does  all  dew  come  from  the  air,  or  does  some  of  it  come  from  the 
ground  through  the  plants?  Why  is  not  this  water,  pumped  up  by  the 
plants,  evaporated? 

8 . What  happens  to  the  dew  if  the  weather  becomes  freezing  during  the 
night?  What  is  hoar  frost?  Why  should  water  change  form  when  it  is 
frozen  ? How  many  forms  of  frost  crystals  can  you  find  on  the  grass  on  a 
frosty  morning?

“When  in  the  night  we  wake  and  hear  the  rain 
Which  on  the  white  bloom  of  the  orchard  falls, 

And  on  the  young,  green  wheat-blades,  where  thought  recalls 
How  in  the  furrow  stands  the  rusting  plow, 

Then  fancy  pictures  what  the  day  will  see — 

The  ducklings  paddling  in  the  puddled  lane , 

Sheep  grazing  slowly  up  the  emerald  slope, 

Clear  bird-notes  ringing,  and  the  droning  bee 
Among  the  lilac's  bloom — enchanting  hope — 

How  fair  the  fading  dreams  we  entertain, 

When  in  the  night  we  wake  and  hear  the  rain!" 

■ — Robert  Burns  Wilson. 


“ The  thin  snow  now  driving  from  the  north  and  lodging  on  my  coat  consists  of  those 
beautiful  star  crystals,  not  cottony  and  chubby  spokes,  but  thin  and  partly  transparent 
crystals.  They  are  about  a tenth  of  an  inch  in  diameter,  perfect  little  wheels  with  six  spokes 
without  a tire,  or  rather  with  six  perfect  little  leaflets,  fern - like,  with  a distinct  straight  and 
slender  midrib,  raying  from  the  center.  On  each  side  of  each  midrib  there  is  a transparent 
thin  blade  with  a crenate  edge.  How  full  of  creative  genius  is  the  air  in  which  these  are 
generated!  I should  hardly  admire  more  if  real  stars  fell  and  lodged  on  my  coat.  Nature 
is  full  of  genius,  full  of  divinity.  Nothing  is  cheap  and  coarse,  neither  dewdrops  nor 
snowflakes .” 

“A  divinity  must  have  stirred  within  them  before  the  crystals  did  thus  shoot  and  set. 
Wheels  of  storm-chariots.  The  same  law  that  shapes  the  earth-star  shapes  the  snow-stars. 
As  surely  as  the  petals  of  a flower  are  fixed,  each  of  these  countless  snow-stars  comes  whirling 
to  earth , pronouncing  thus,  with  emphasis,  the  number  six.” — Thoreau’s  Journal.

THE  WEATHER 
By  Wilford  M.  Wilson 

Section  Director,  U.  S.  Weather  Bureau,  and  Professor  of  Meteorology 
in  Cornell  University. 

The  atmosphere,  at  the  bottom  of  which  we 
live,  may  be  compared  to  a great  ocean  of  air, 
about  two  hundred  miles  deep,  resting  upon  the 
earth.  The  changes  and  movements  that  take 
place  in  this  ocean  of  air,  the  storms  that  invade 
it,  the  clouds  that  float  in  it,  the  sunshine,  the 
rain,  the  dew,  the  sleet,  the  frost,  the  snow,  and 
the  hail  are  termed  “weather.”  We  live  in  it; 
we  partake  of  its  moods;  we  reflect  its  sunshine 
and  shadows;  it  invades  the  everyday  affairs 
of  life,  influences  every  business  and  social 
activity,  and  molds  the  character  of  nations; 
and  yet  nearly  everything  we  know  about  the 
weather  has  been  learned  within  the  lifetime 
of  the  present  generation.  N ot  that  the  weather 
did  not  interest  men  of  early  times,  but  the 
problem  appeared  to  be  so  complicated  and  so 
complex  that  it  baffled  their  utmost  endeavors.

The  Temple  of  the  Winds  at  Athens 

The  Temple  of  the  Winds,  erected  probably 
about  five  hundred  years  B.  C.,  indicates  the 
knowledge  f the  weather  possessed  by  the 
ancient  Greeks.  This  temple  is  a little  octagon 
tower,  the  eight  sides  of  which  face  the  eight 
principal  winds.  On  each  of  its  eight  sides  is  a 
human  figure  cut  in  the  marble,  symbolizing 
the  kind  of  weather  the  wind  from  that  particu- 
lar direction  brought  to  Athens. 

Boreas,  the  cold  north  wind,  is  represented 
by  the  figure  of  an  old  man  wearing  a thick 
mantle,  high  buskins  (boots)  and  blowing  on 
a “weathered  horn.  ” The  northeast  wind,  which 
brought,  and  still  brings  to  Athens,  cold,  snow,  sleet  and  hail,  is  symbolized 
by  a man  with  a severe  countenance  who  is  rattling  slingstones  in  a 
shield,  thus  expressing  the  noise  made  by  the  falling  hail  and  sleet. 

The  east  wind,  which  brought  weather  favorable  to  the  growth  of  vegeta- 
tion, is  shown  by  the  figure  of  a beautiful  youth  bearing  fruit  and  flowers  in 
his  tucked-up  mantle. 

Natos,  the  warm  south  wind,  brought  rain,  and  he  is  about  to  pour  the 
water  over  the  earth  from  the  jar  which  he  carries. 

Lips,  the  southwest  wind,  beloved  of  the  Greek  sailors,  drives  a ship 
before  him,  while  Zephros,  the  gentle  west  wind,  is  represented  by  a youth 
lightly  clad,  scattering  flowers  as  he  goes. 

, The  northwest  wind,  which  brought  dry  and  sometimes  hot  weather  to 
Athens,  is  symbolized  in  the  figure  of  a man  holding  a vessel  of  charcoal 
in  his  hands.  Thus,  the  character  of  the  weather  brought  by  each  separate 
wind  is  fixed  in  stone,  and  from  this  record  we  learn  that,  even  with  the 
lapse  of  twenty  centuries,  there  has  come  no  material  change. 


Historical 

There  is  no  record  of  any  rational  progress 
having  been  made  in  the  study  of  the  weather 
until  about  the  middle  of  the  seventeenth  cen- 
tury, when  Torricelli  discovered  the  principles 
of  the  barometer.  This  was  a most  important 
discover}'  and  marks  the  beginning  of  the 
modem  science  of  meteorology.  Soon  after 
Torricelli’s  discovery  of  the  barometer  his  great 
teacher,  Galileo,  discovered  the  thermometer, 
and  thus  made  possible  the  collection  of  data 
upon  which  all  meteorological  investigations 
are  based.  About  one  hundred  years  after 
the  discovery  of  the  barometer,  Benjamin 
Franklin  made  a discovery  of  equal  import- 
ance. He  demonstrated  that  storms  were 
eddies  in  the  atmosphere,  and  that  they  pro- 
gressed or  moved  as  a whole,  along  the  surface  of  the  earth. 

It  might  be  interesting  to  leam  how  Franklin  made  this  discovery. 
Franklin,  being  interested  at  that  time  in  astronomy,  had  arranged  with  a

friend  in  Boston  to  take  observations  of  a lunar  eclipse  at  the  same  time 
that  he,  himself,  was  to  take  observations  at  Philadelphia.  On  the  night  of 
the  eclipse  a terrific  northeast  wind  and  rain  storm  set  in  at  Philadelphia, 
and  Franklin  was  unable  to  make  any  observations.  He  reasoned,  that  as 
the  wind  blew  from  the  northeast,  the  storm  must  have  been  experienced  in 
Boston  before  it  reached  Philadelphia.  But  imagine  his  surprise,  when  he 
heard  from  his  friend  in  Boston  that  the  night  had  been  clear  and  favorable 
for  observation,  but  that  a fierce  wind  and  rain  storm  set  in  on  the  following 
morning.  Franklin  determined  to  investigate.  He  sent  out  letters  of 
inquiry  to  all  surrounding  mail  stations,  asking  for  the  time  of  the  beginning 
and  ending  of  the  storm,  the  direction  and  strength  of  the  wind,  etc.  When 
the  information  contained  in  the  replies  was  charted  on  a map  it  showed 
that,  at  all  places  to  the  southwest  of  Philadelphia,  the  beginning  of  the 
storm  was  earlier  than  at  Philadelphia,  while  at  all  places  to  the  northeast 
of  Philadelphia  the  beginning  of  the  storm  was  later  than  at  Philadelphia. 
Likewise,  the  ending  was  earlier  to  the  southwest  and  later  to  the  northeast 
of  Philadelphia  than  at  Philadelphia.  He  also  found  that  the  winds  in 
every  instance  passed  through  a regular  sequence,  setting  in  from  some 
easterly  point  and  veering  to  the  south  as  the  storm  progressed,  then  to  the 
southeast  and  finally  to  the  west  or  northwest  as  the  storm  passed  away  and 
the  weather  cleared. 

A further  study  of  these  facts  convinced  Franklin  that  the  storm  was  an 
eddy  in  the  atmosphere,  and  that  the  eddy  moved  as  a whole  from  the 
southwest  toward  the  northeast,  and  that  the  winds  blew  from  all  directions 
toward  the  center  of  the  eddy,  impelled  by  what  he  termed  suction. 

Franklin  was  so  far  in  advance  of  his  time  that  his  ideas  about  storms 
made  little  impression  on  his  contemporaries,  and  so  it  remained  for 
Redfield,  Espy,  Loomis,  Henry  and  Maury  and  other  American  meteorolo- 
gists, a hundred  years  later,  to  show  that  Franklin  had  gained  the  first 
essentially  correct  and  adequate  conception  of  the  structure  and  movement 
of  storms. 

During  the  first  half  of  the  nineteenth  century,  considerable  progress 
was  made  in  the  study  of  storms,  principally  by  American  meteorologists, 
among  whom  was  William  Redfield  of  New  York,  who  first  demonstrated 
that  storms  had  both  a rotary  and  progressive  movement.  James  Espy 
followed  Redfield  in  the  construction  of  weather  maps,  although  he  had 
already  published  much  on  meteorological  subjects  before  the  latter  entered 
the  field. 

Professor  Joseph  Henry,  Secretary  of  the  Smithsonian  Institution  at 
Washington,  was  the  first  to  prepare  a daily  weather  map  from  observations 
collected  by  telegraph.  He  made  no  attempt  to  make  forecasts,  but  used 
his  weather  map  to  demonstrate  to  members  of  Congress  the  feasibility  of  a 
national  weather  service. 

An  incident  occurred  during  the  Crimean  War  that  gave  meteorology 
a great  impetus,  especially  in  Europe.  On  November  10th,  1854,  while 
the  French  fleet  was  at  anchor  in  the  Black  Sea,  a storm  of  great  intensity 
occurred  which  practically  destroyed  its  effectiveness  against  the  enemy. 
The  investigation  that  followed  showed  that  the  storm  came  from  western 
Europe,  and  had  there  been  adequate  means  of  communication  and  its 
character  and  direction  of  progress  been  known,  it  would  have  been 
possible  to  have  warned  the  fleet  of  its  approach  and  thus  afforded  an 
opportunity  for  its  protection.

This  report  created  a profound  impression  among  scientific  men  and 
active  measures  were  taken  at  once  that  resulted  in  the  organization  of 
weather  services  in  the  principal  countries  of  Europe  between  1855  and 
i860. 

The  work  of  Professor  Henry,  Abbe,  and  others  in  this  country  would, 
doubtless,  have  resulted  in  such  an  organization  in  the  United  States  in  the 
early  6o’s,  had  not  the  Civil  War  intervened,  absorbing  public  attention  to 
the  exclusion  of  other  matters.  It  was  not  until  1870,  that  Dr.  Increase  A. 
Lapham  of  Milwaukee,  in  conjunction  with  Representative  Paine  of  that 
city,  was  able  so  to  present  the  claims  for  a national  weather  service  that 
the  act. was  finally  passed  that  gave  birth  to  the  present  meteorological 
bureau  in  the  United  States.  Dr.  Lapham  issued  from  Chicago  on  Novem- 
ber 10,  1871,  the  first  official  forecast  of  the  weather  made  in  this  country. 

The  Atmosphere 

What  is  known  about  the  atmosphere  of  our 
earth  has  been  learned  from  the  exploration  of 
a comparatively  thin  layer  at  the  bottom. 
There  is  reason  to  believe  that  the  atmosphere 
extends  upwards  about  two  hundred  miles  from 
the  surface  of  the  earth.  W e have  a great  mass 
of  observations  made  at  the  surface,  some  on 
mountains,  but  few  in  the  free  air  more  than 
a few  miles  above  the  surface.  Our  knowledge 
of  the  upper  atmosphere  is,  therefore,  in  the 
nature  of  conclusions  drawn  from  such  obser- 
vations as  are  at  hand,  and  is  subject  to  changes 
and  modifications  as  the  facts  become  known 
by  actual  observation. 

During  the  past  few  years  a concerted  effort  has  been  made  in  various 
parts  of  the  world  to  explore  the  upper  atmosphere  by  means  of  kites  and 
balloons,  carrying  meteorological  instruments  that  automatically  record 
the  temperature,  pressure,  humidity,  velocity  and  direction  of  the  wind,  etc. 
In  this  country  this  work  has  been  carried  on  principally  at  the  Mount 
Weather  Observatory,  which  is  located  in  Loudon  County,  Virginia,  and  is 
under  the  direction  of  the  United  States  Weather  Bureau  and  at  Blue  Hill 
Observatory,  a private  institution  located  near  Boston  and  supported  by 
Professor  Lawrence  Rotch.  From  observations  thus  obtained  much  has 
been  learned  about  the  upper  atmosphere  that  was  not  even  suspected 
before.  Some  theories  have  been  confirmed  and  some  destroyed,  but  this 
line  of  research  is  gradually  bringing  us  nearer  the  truth. 

Air  as  a Gas 

Air  is  not  a simple  substance,  as  was  once  supposed,  but  is  composed  of 
a number  of  gases,  each  one  of  which  tends  to  form  an  atmosphere  of  its 
own,  just  as  it  would  if  none  of  the  other  gases  were  present.  The  different 
gases  of  the  atmosphere  are  not  chemically  combined  but  are  very 
thoroughly  mixed,  as  one  might  mix  sugar  and  salt.  Samples  of  air  col- 
lected from  all  parts  of  the  world  show  that  the  relative  proportion  of  the 
gases  forming  the  atmosphere  is  practically  uniform.

The  Composition  of  Air 

Dry  air  is  composed  chiefly  of  oxygen  and  nitrogen.  There  are,  how- 
ever, small  quantities  of  carbon  dioxide,  argon,  helium,  krepton,  neon, 
hydrogen  and  xenon,  and  probably  other  gases  yet  to  be  discovered. 

The  approximate  proportion,  by  volume  is  as  follows:  Nitrogen  78 

parts,  oxygen  21  parts,  argon  1 part,  carbon-dioxide  .03  parts,  and  krepton 
helium  and  xenon  a trace.  Pure  dry  air  does  not  exist  in  nature,  so  there  is 
always  present  in  natural  air  a variable  amount  of  water  vapor,  depending 
upon  the  temperature  and  the  source  of  supply.  Besides  these,  which  may 
be  termed  the  permanent  constituents  of  the  atmosphere,  many  other  sub- 
stances are  occasionally  met  with.  Lightning  produces  minute  quantities 
of  ammonia,  nitrous  acid  and  ozone.  Dust  comes  from  the  earth,  salt  from 
the  sea,  while  innumerable  micro-organisms,  most  of  which  are  harmless, 
besides  the  pollen  and  spores  of  plants,  are  frequently  found  floating  in  the 
atmosphere.  Recent  investigations  in  atmospheric  electricity  lead  to  the 
conclusion  that  electric  ions  are  also  present,  and  perform  important  func- 
tions, especially  with  respect  to  precipitation. 

Oxygen 

Oxygen  is  one  of  the  most  common  substances.  It  exists  in  the  atmos- 
phere as  a transparent,  odorless,  tasteless  gas.  It  combines  with  hydrogen 
to  form  the  water  of  the  oceans,  and  with  various  other  substances  to  form 
much  of  the  solid  crust  of  the  earth.  Chemically,  it  is  a very  active  gas, 
and  because  of  its  tendency  to  unite  with  other  substances  to  form  chemical 
compounds,  it  is  believed  that  the  volume  of  oxygen  now  in  the  atmosphere, 
is  less  than  during  the  early  history  of  the  earth.  It  supports  combustion 
by  combining  with  carbon  and  other  substances,  producing  light  and  heat. 
It  combines  with  some  of  the  organic  constituents  of  the  blood,  through  the 
function  of  respiration,  which  is  in  itself  a slow  process  of  combustion,  and 
thus  supports  life  and  maintains  the  bodily  heat. 

Nitrogen 

Nitrogen  forms  the  largest  proportion  of  the  atmosphere,  but  unlike 
oxygen  it  is  a very  inert  substance,  uniting  with  no  element  at  ordinary 
temperatures,  and  at  high  temperatures  with  only  a few;  and  when  so 
united  the  bonds  that  hold  it  are  easily  broken  and  the  gas  set  free.  For 
this  reason,  it  is  utilized  in  the  manufacture  of  explosives,  such  as  gun- 
powder, guncotton,  nitroglycerine,  dynamite,  etc.  Its  office  in  the  atmos- 
phere appears  to  be  to  give  the  air  greater  weight  and  to  dilute  the  oxygen, 
for  in  an  atmosphere  of  pure  oxygen  a fire  once  started  could  not  be  con- 
trolled. Although  nitrogen  does  not  contribute  directly  to  animal  life,  in 
that  it  is  not  absorbed  and  assimilated  from  the  air  direct  as  oxygen  is, 
nevertheless,  it  is  a very  important  element  of  food  both  for  animals  and 
plants,  and  in  combination  with  other  substances  forms  a large  proportion 
of  animal  and  vegetable  tissues. 

Carbon  Dioxide 

Carbonic  acid  gas,  known  chemically  as  C02  is  a product  of  combustion. 
It  results  from  the  burning  of  fuel  and  is  exhaled  by  the  breathing  of  ani- 
mals. It  also  results  from  certain  chemical  reactions.  The  amount  in  the 
atmosphere  varies  slightly,  being  somewhat  greater  at  night  than  by  day 


862 


Handbook  of  Nature-Study 


and  during  cloudy  weather  than  during  clear  weather.  Air  containing 
more  than  0.06%  of  carbon  dioxide  is  not  fit  to  breathe,  not  because  air 
loaded  with  carbon  dioxide  is  poisonous,  but  because  it  excludes  the  oxygen 
and  thus  produces  death  by  suffocation.  It  is  considerably  heavier  than 
air,  and  in  certain  localities,  where  it  is  emitted  from  the  ground,  accumu- 
lates in  low  places  in  such  quantities  as  to  suffocate  animals.  Death’s 
Gulch,  a deep  ravine  in  Yellowstone  Park,  and  Dog’s  Grotto  near  Naples, 
are  examples.  At  the  latter  place,  the  gas,  on  account  of  being  heavier  than 
air,  lies  so  close  to  the  ground  that  a man,  standing  erect,  will  have  no 
difficulty  in  breathing,  while  a dog  will  die  of  suffocation.  It  also  accumu- 
lates in  unused  wells,  cisterns  and  mines,  and  can  usually  be  detected  by 
lowering  a lighted  candle.  If  carbon  dioxide  is  present  in  large  quantities, 
the  candle  will  be  extinguished  because  of  the  lack  of  oxygen  to  support 
combustion. 

Although  carbon  dioxide  forms  but  a small  proportion  of  the  atmos- 
phere, it  is  a very  important  element  in  plant  life.  Animals  consume 
oxygen  and  exhale  carbon  dioxide,  while  plants  take  in  carbon  dioxide  and 
give  off  oxygen ; thus,  the  amount  of  these  gases  in  the  atmosphere  is  main- 
tained at  an  equilibrium.  Plants,  through  their  leaves,  absorb  the  carbon 
dioxide,  which  is  decomposed  by  the  sunlight,  returning  the  oxygen  free 
into  the  air,  while  the  carbon  is  used  to  build  up  plant  tissue. 

Other  Gases 

Argon,  on  account  of  its  resemblance  to  nitrogen,  was  not  discovered 
until  1894,  having  been  included  with  the  nitrogen  in  all  previous  analyses 
of  air.  It  constitutes  about  1%  of  air  by  volume.  Krepton,  neon  and 
xenon  exist  in  minute  quantities  and  have  some  interest  chemically,  but 
little  for  the  meteorologists.  Helium  and  hydrogen  probably  exist  at  great 
elevations  in  the  atmosphere. 

Water  Vapor 

The  vapor  of  water  in  the  atmosphere  varies  from  about  one  per  cent 
for  arid  regions  to  about  five  per  cent,  of  the  weight  of  the  air  for  warm, 
humid  regions.  It  is  a little  over  one-half  as  heavy  as  air  and  moist  air  is, 
therefore,  lighter  than  dry  air;  but  the  increase  of  moisture  near  the  center 
of  cyclones  has  only  a slight  effect  in  reducing  the  pressure.  The  amount  of 
vapor  decreases  very  rapidly  with  elevation,  and  probably  disappears  at  an 
elevation  of  five  or  six  miles  above  the  surface.  The  amount  of  water  in 
the  form  of  vapor  that  can  exist  in  the  atmosphere  increases  with  the 
temperature,  being  .54  grains  Troy  per  cubic  foot  at  zero  temperature  and 
14.81  at  90°.*  When  the  air  has  taken  up  all  the  moisture  it  can  contain 
at  a given  temperature  it  is  said  to  be  saturated. 

The  dewpoint  is  the  temperature  at  which  saturation  occurs.  If  the 
air  is  saturated,  the  temperature  of  the  air  and  the  dewpoint  will  be  the 
same,  but  if  the  air  is  not  saturated  the  dewpoint  will  be  below  that  of  the 
air. 

Relative  humidity  is  expressed  in  percentages  of  the  amount  necessary 
to  saturate.  If  the  air  contains  one-half  enough  vapor  to  saturate  it,  the 
relative  humidity  will  be  50%;  if  one-fourth,  enough  to  saturate,  25%;  if 
saturated  100%  etc. 

The  absolute  humidity  is  the  actual  amount  of  water  in  the  form  of 
vapor  in  the  air,  and  is  usually  expressed  by  weight  in  grains  per  cubic  foot

or  in  inches  of  mercury,  the  weight  of  which  would  counterbalance  the 
weight  of  the  vapor  in  the  air.  The  conditions  present  in  a volume  of. 
saturated  air  at  a temperature  of  3 2 0 may  be  expressed  as  follows : Relative 
humidity  100%;  dewpoint  3 20;  absolute  humidity  2 . 1 1 grains  per  cu.  ft. 
or  .18  inch. 

Pressure  of  Atmosphere 

Although  the  atmosphere  is  composed  of  these  various  gases,  it  acts  in 
all  respects  like  a simple,  single  gas.  It  is  very  elastic,  easily  compressed, 
expands  when  heated  and  contracts  when  cooled.  It  is  acted,  upon  by 
gravity  and,  therefore,  has  weight  and  exerts  pressure,  which  at  sea  level 
amount  to  about  14.7  pounds  on  each  square  inch  of  the  surface.  Because 
it  is  compressible  and  has  weight,  it  is  more  dense  at  the  surface  than  at  any 
elevation  above  the  surface,  and  as  we  ascend  in  the  atmosphere  the  weight 
or  pressure  decreases  in  proportion  to  the  weight  of  that  part  of  the  atmos- 
phere left  below.  The  weight  or  pressure  of  the  atmosphere  is  measured 
by  means  of  a barometer  and  is  expressed  in  terms  of  inches  of  mercury. 
The  normal  atmosphere  at  sea  level  will  sustain  a column  of  mercury 
about  thirty  inches  high,  and  we  therefore  say  that  the  normal  pressure 
of  the  atmosphere  is  thirty  inches.  (See  Lessons  on  air  pressure  and  the 
barometer.) 

The  Height  of  the  Atmosphere  ■ 

The  air  that  surrounds  the  earth  is  called  its 
atmosphere,  but  it  is  a rather  curious  fact  that  the 
earth  has  really  ten  atmospheres  and  may  have 
others  not  yet  discovered. 

The  air  near  the  surface  is  a mixture  of  eight 
different  gases,  and  each  individual  gas  arranges 
itself  so  as  to  form  an  atmosphere  just  as  it  would 
if  no  other  gases  were  present.  Thus,  the  earth  is 
surrounded  by  an  atmosphere  of  oxygen,  an 
atmosphere  of  nitrogen,  one  of  carbon  dioxide, 
one  of  water  vapor,  one  each  of  argon,  krypton, 
neon,  and  xenon,  while  hydrogen  and  helium 
are  believed  to  exist  at  great  elevations  above  the 
earth’s  surface. 

These  gases  are  kept  from  flying  off  into  space  by  the  force  of  gravity, 
just  as  a piece  of  iron,  stone,  or  a building  is  held  fast  to  the  earth  by  the 
same  force.  Gravity  acts  with  greater  force  on  some  things  than  on  others. 
For  example,  a piece  of  iron  is  pulled  down  by  gravity  with  greater  force 
than  is  a piece  of  wood  of  the  same  size ; likewise,  a piece  of  lead  is  pulled 
down  with  greater  force  than  a piece  of  iron.  We,  therefore,  say  that  iron  is 
heavier  than  wood  and  that  lead  is  heavier  than  iron,  simply  because  gravity 
acts  with  greater  force  on  the  one  than  on  the  other.  The  weight  of  gases 
differ  just  as  the  weight  of  different  solids,  such  as  lead,  wood  or  iron  differ. 
For  instance,  nitrogen  is  14  and  oxygen  16  times  heavier  than  hydrogen. 

Gases  having  the  least  weight  extend  upward  the  farthest,  because  the 
lighter  the  gas  the  greater  its  expansive  force.  Every  boy  who  rides  a 
bicycle  takes  advantage  of  the  expansive  force  of  air  when  he  pumps  his 
tires.  The  air  is  compressed  by  the  pump  into  the  tube  and  the  expansive 
force  exerted  by  the  air  in  trying  to  expand  makes  the  tire  “stand  up.”  If 
it  requires  10  pounds  pressure  to  compress  the  gas  into  the  tube,  the  expan- 
sive force  will  be  just  ten  pounds.

Handbook  of  Nature-Study 

There  are  two  forces  in  constant  operation  on  each  gas  that  surrounds 
the  earth,  viz.,  expansive  force  and  gravity.  Expansive  force  pushes  the 
gas  up  and  gravity  pulls  it  down,  but  the  force  of  gravity  decreases  as  the 
distance  from  the  center  of  the  earth  increases,  so  there  is  a point  at  a cer- 
tain distance  above  the  earth  where  the  two  forces  just  balance  each  other, 
and  each  gas  will  expand  upward  to  that  point  but  will  not  rise  beyond  it. 
Therefore,  if  we  know  the  expansive  force  of  a gas  and  the  rate  at  which 
gravity  decreases,  it  is  possible  to  calculate  the  height  to  which  the  differ- 
ent gases  that  compose  the  air  will  rise. 

In  this  way  it  has  been  determined  that  carbon  dioxide,  which  is  one  of 
the  heavier  gases,  extends  upward  about  ten  miles,  water  vapor  about  12 
miles,  oxygen  about  30  miles  and  nitrogen  about  35  miles  while  hydrogen 
and  helium,  the  lightest  gases  known,  do  not  appear  at  the  surface  at  all,  but 
probably  exist  at  a height  of  from  30  miles  to  possibly  200  miles.

The  zone  of  twilight  in  midwinter. 


From  Todd’s  New  Astronomy. 

There  are  other  ways  in  which  we  are  able  to  gain  some  idea  of  the 
approximate  height  at  which  there  is  an  appreciable  atmosphere.  When 
the  rays  of  light  from  the  sun  enter  our  atmosphere  they  are  broken  up  or 
scattered — diffracted — so  that  the  atmosphere  is  partially  lighted  for 
some  time  before  sunrise  and  after  sunset.  This  is  called  twilight.  If  there 
were  no  atmosphere,  there  would  be  no  twilight,  and  darkness  would  fall  the 
instant  the  sun  passed  below  the  horizon.  Twilight,  which  is  caused  by  the 
sun  shining  on  the  upper  atmosphere,  is  perceptible  until  the  sun  is  about 
1 6°  below  the  horizon.*  ' From  this  it  is  calculated  that  the  atmosphere  has 
sufficient  density  at  a height  of  40  miles  to  scatter,  or  diffract,  sunlight. 

Observations  of  meteors,  commonly  called  shooting  stars,  indicate  that 
there  is  an  appreciable  atmosphere  at  a height  of  nearly  2 00  miles.  Meteors 
are  solid  bodies  flying  with  great  velocity  through  space.  Occasionally 
they  enter  our  atmosphere.  Their  velocity  is  so  great  that  the  slight 
resistance  offered  by  the  air  generates  enough  heat  by  friction,  or  by  the 
compression  of  the  air  in  the  path  of  the  meteor,  to  make  it  red  hot  or  to 
bum  it  up  before  it  reaches  the  bottom  of  the  atmosphere.  Only  the  largest 
meteors  reach  the  earth. 

When  a meteor  is  observed  by  two  or  more  persons  at  a known  distance 
from  each  other,  and  the  angle  which  the  line  of  vision  makes  with  the 
horizon  is  noted  by  each,  it  is  a simple  matter  to  calculate  the  distance  from 
the  earth  where  the  lines  of  vision  intersect,  and  thus  determine  the  height 
of  the  meteor.  In  this  way,  reliable  observations  have  given  the  height  at 
which  there  is  sufficient  density  in  the  atmosphere  to  render  meteors  lumin- 
ous as  188  miles.

Temperature  of  the  Atmosphere 

The  condition  of  the  atmosphere  with  respect  to  its  temperature  is 
determined  by  means  of  the  thermometer.  This  instrument  is  in  such 
common  use  that  a detailed  description  is  not  necessary.  It  might  be 
interesting  to  note  that  the  instrument  invented  by  Galileo  was  very 
different  from  those  now  in  use.  Galileo’s  original  thermometer  was  what 
is  known  as  an  air  thermometer,  and  its  operation  when  subjected  to  differ- 
ent degrees  of  heat  or  cold  depended  upon  the  expansion  and  contraction  of 
air  instead  of  mercury  or  alcohol.  It  had  one  serious  defect,  viz. , the  length 
of  a column  of  air  is  affected  by  pressure  as  well  as  by  temperature  and  it 
was,  therefore,  necessary,  when  using  this  thermometer,  to  obtain  the  pres- 
sure of  the  atmosphere  by  means  of  the  barometer  before  the  temperature 
could  be  determined.  This  is  obviated  in  the  modern  thermometer  by  the 
use  of  mercury  or  alcohol  in  a vacuum  tube.  Mercury  is  not  used  when  it 
is  expected  to  register  very  low  temperatures,  because  it  congeals  at  about 
45  degrees  below  zero  Fahr. 

Thermometer  Scales  in  Use 

There  are  three  systems  in  common  use  for  marking  the  degrees  on  the 
scale,  viz.,  Fahrenheit,  Centigrade  and  Reaumur. 

The  Fahrenheit  scale  was  the  invention  of  a German  by  that  name,  but  it 
is  worthy  of  note  that  this  scale  is  used  principally  by  English  speaking 
nations  and  is  not  in  common  use  in  Germany.  Fahrenheit  found  that  by 
mixing  snow  and  salt  he  was  able  to  obtain  a very  low  temperature,  and 
believing  that  the  temperature  thus  obtained  was  the  lowest  possible  he 
started  his  scale  at  that  point,  which  he  called  zero.  He  then  fixed  the 
freezing  temperature  of  water  32  degrees  above  this  zero,  and  the  boiling 
point  of  water  at  212  degrees.  There  are,  therefore,  180  divisions  or  de- 
grees between  the  freezing  and  boiling  point  of  water  on  the  Fahrenheit 
scale. 

The  Centigrade  scale  starts  with  zero  at  the  freezing  point  of  water  and 
makes  the  boiling  point  100.  Thus  180  degrees  on  the  Fahrenheit  scale 
equal  100  degrees  on  the  Centigrade.  The  Fahrenheit  degree  is,  therefore, 
only  a little  more  than  half  as  large,  to  be  exact  five-ninths  of  a degree,  as  a 
degree  on  the  Centigrade  scale.  The  Centigrade  scale  is  in  common  use  in 
France  and  is  used  almost  exclusively  in  all  scientific  work  throughout  the 
world. 

The  Reaumur  scale  is  used  generally  in  Russia  and  quite  commonly  in 
some  parts  of  Europe,  especially  in  Germany.  On  this  scale  the  zero  is 
placed  at  the  freezing  point  of  water  and  the  boiling  point  at  80  degrees. 
The  divisions  are,  therefore,  larger  than  those  of  the  Centigrade  scale  and 
more  than  twice  as  large  as  the  Fahrenheit.  The  general  use  of  these 
different  scales  has  led  to  endless  confusion  and  made  the  comparison  of 
records  difficult,  so  that  even  at  the  present  time  when  making  a tempera- 
ture record  it  is  necessary  to  indicate  the  scale  in  use. 

Distribution  of  the  Temperature  and  Pressure 

The  heat  received  on  the  earth  from  the  sun  is  the  controlling  factor  in 
all  weather  conditions.  If  the  earth  were  composed  of  all  land  or  all  water, 
and  the  amount  of  heat  received  were  everywhere  the  same  throughout  the 
year,  there  would  be  no  winds,  no  storms  and  probably  no  clouds  and  no 


866

rain,  because  the  force  of  gravity,  which  acts  on  everything  on  the  earth’s 
surface  and  on  the  air  as  well,  would  soon  settle  all  differences  and  the  at- 
mosphere would  become  perfectly  still.  But  the  earth  is  composed  of  land 
and  water  and  the  land  heats  up  more  rapidly  under  sunshine  than  the 
water  and  also  gives  off —“radiates”  its  heal  more  rapidly  than  water.  As 
a result,  the  air  over  the  land  is  warmer  in  summer  than  the  air  over  the 
water.  During  the  winter  this  is  reversed,  and  the  air  over  the  oceans  is 
warmer  than  the  air  over  the  land.  The  great  ocean  currents,  by  carrying 
the  heat  from  the  equatorial  regions  toward  the  poles,  and  by  bringing  the 
cold  from  the  polar  regions  toward  the  equator,  assist  in  maintaining  a con- 
stant difference  in  temperature  between  the  continents  and  the  adjacent 
oceans. 

Furthermore,  the  fact  that  the  path  of  the  earth  about  the  sun  is  not  a 
circle  but  an  ellipse,  and  that  the  axis  of  the  earth  is  not  perpendicular  to 
the  plane  of  its  orbit,  result  in  an  unequal  distribution  of  heat  over  the  sur- 
face. It  is  always  warmer  near  the  equator  than  at  the  poles,  and  warmer 
in  summer  than  in  winter.  All  these  differences  in  temperature  cause 
corresponding  differences  in  density,  which,  in  turn,  cause  differences  in 
weight  or  pressure  over  various  parts  of  the  earth’s  surface.  These  changes 
are,  in  no  way,  the  result  of  chance  but  are  determined  by  the  operation  of 
fixed  natural  laws,  and  with  this  in  mind  we  may  now  take  up  the  study  of 
the  winds  of  the  world. 

The  Winds  of  the  World 

The  general  circulation  of  the  atmosphere  may 
be  best  studied  by  disregarding  those  smaller  differ- 
ences of  temperature  and  pressure  that  result  from 
local  causes  and  by  viewing  the  earth  and  its  atmos- 
phere as  a whole,  considering  only  those  larger 
differences  which  are  in  constant  operation.  In 
the  great  oceans  of  the  world  we  find  the  water  con- 
stantly moving  in  a very  systematic  manner,  and 
we  call  this  system  of  movements  ocean  currents. 
The  Gulf  Stream,  the  Equatorial  Current,  the  Japan 
Current  and  others  may  be  likened  to  great  rivers 
of  water  moving  systematically  on  their  courses 
in  the  ocean. 

There  are  greater  rivers  of  air  in  the  atmosphere 
than  any  in  the  oceans,  and  they  move  on  their 
courses  with  equally  systematic  precision  and  in  obedience  to  fixed  laws, 
which  we  may  in  a measure  understand. 

The  river,  at  the  bottom  of  which  we  live,  is  broad  and  deep,  extending 
in  width  from  Florida  northward,  nearly  to  the  north  pole.  It  flows  from 
west  to  east  circling  the  globe  and  its  name  is  The  Prevailing  Westerlies. 
The  other  river  in  this  hemisphere  extends  southward  from  latitude  about 
35°  nearly  to  the  equator.  Its  name  is  The  Northeast  Trade  Winds. 

In  the  southern  hemisphere  are  two  similar  rivers,  one  extending  south- 
ward from  latitude  about  30°  nearly  to  the  south  pole  with  its  current, 
like  its  counterpart  in  the  northern  hemisphere,  flowing  from  west,  to 
east,  circling  the  globe.  It  is  also  called  The  Prevailing  Westerlies. 
The  other  river  in  the  southern  hemisphere  extends  from  about  latitude 
30°  northward  nearly  to  the  equator  and  flows  from  the  southeast 


Snow  crystal.

toward  the  northwest,  hence  the  name  Southeast  Trade  Winds. 
The  dividing  line,  or  bank,  between  the  rivers  in  each  hemisphere 
belts  the  earth  at  about  3 50  north  and  3 o°  south  of  the  equator.  Why 
does  the  air  move  and  why  does  it  move  in  such  a regular,  systematic 
manner  ? To  answer  these  questions  we  will  rely  upon  gravity,  the  heat 
from  the  sun  and  the  effect  of  the  rotation  of  the  earth  on  moving  wind 
currents. 

Everyone  knows  that  water  flows  down  hill  because  of  the  force  of 
gravity.  Gravity  is  nature’s  great  peacemaker.  It  is  always  trying  to 
settle  disturbances,  even  things  up,  smooth  them  over.  If  there  were 
no  winds  to  bring  rain  to  the  land  or  to  stir  up  the  ocean,  gravity  would 


soon  run  all  the  water  into  the  lakes  and  the  seas,  and  then  smooth  them 
out  like  sheets  of  glass;  and  if  there  were  nothing  to  stir  up  the  winds, 
gravity  would  soon  settle  all  differences  in  the  atmosphere  and  the  air  would 
become  perfectly  quiet.  So  gravity  is  kept  busy  trying  to  smooth  out  the 
water  which  the  wind  stirs  up,  at  the  same  time  trying  to  quiet  the  winds 
which  are  stirred  up  by  the  heat  of  the  sun. 

Tyndall  says  that  heat  is  a mode  of  motion,  that  when  heat  is  imparted 
to  a substance  the  molecules  of  which  it  is  composed  are  set  into  very  rapid 
vibration.  They  are  continually  trying  to  get  away  from  each  other  and 
usually  succeed  in  getting  more  space,  and  thus  increase  the  size  or  volume 
of  the  substance,  or,  in  other  words,  expand  it.  Iron,  brass,  copper,  water 
and  many  other  substances  expand  under  heat.  Air  is  a gas  and  expands 
very  rapidly  when  heated.  One  cubic  foot  of  cold  air  becomes  two  cubic 
feet  when  heated.  Now  gravity  pulls  things  down  toward  the  center  of 
the  earth  in  accordance  with  their  weight-density,  and  a cubic  foot  of  cold 
air,  being  more  dense  and  thus  heavier  than  an  equal  volume  of  warm  air,  is 
pulled  down  with  greater  force.  We,  therefore,  say  that  warm  air  is  lighter 
than  cold  air,  and  if  lighter  it  will  rise.  What,  it  actually  does  is  to  press 
equally  in  all  directions  and  when  a place  is  found  where  there  is  less 


868 


Handbook  of  Nature-Study 


resistance  than  elsewhere  it  moves  in  that  direction.  So  when  heat  causes 
air  to  expand  and  become  lighter  than  the  surrounding  cool  air,  it  moves, 
and  air  in  motion  is  wind. 

This  diagram  represents  a section  of  the  atmosphere  over  a broad,  level 
plain  with  the  air  at  rest  and  pressing  down  equally  on  every  part  of  the  sur- 
face. The  dotted  line  H represents  the  top  of  the  quiet  atmosphere.  Such 
a condition  occurs  frequently  at  night  after  the  heat  from  the  sun  is  with- 
drawn and  gravity  has  settled  the  atmosphere.  When  the  rays  of  the  sun 
fall  upon  the  earth  upon  which  this  quiet  air  rests  they  warm  the  earth  first, 
then  the  layer  of  air  immediately  in  contact  with  the  surface,  so  the  atmos- 
phere is  heated  from  the  bottom  upward.  We  will  assume  that  the  layer 
of  air  between  the  earth  and  the  dotted  line,  G,  is  thus  heated  to  a higher 
temperature  than  the  air  above  it.  It  will,  therefore,  expand.  It  cannot 
expand  downward  because  of  the  earth.  It  cannot  expand  much  laterally 
because  it  is  pressed  upon  by  air  that  is  also  seeking  more  space.  It,  there- 
fore, expands  upward  as  represented  by  the  line  ABC.  Now  in  expanding 


upward  it  lifts  all  the  air  above  it  and  the  line  H,  representing  the  top  of  the 
atmosphere,  will  become  bowed  upward  also  as  indicated  by  the  line  A'B'C'. 
As  a result,  the  air  at  the  top  of  the  atmosphere  over  the  warm  center 
slides  down  the  slopes  on  either  side  toward  the  cool  margins.  As  soon  as 
the  flow  of  air  away  from  the  warm  center  begins,  just  that  instant  the 
pressure  upon  the  heated  layer  at  the  surface  is  relieved  and  the  warm  air 
rushes  upward  (is  pushed  upward)  and  the  whole  circulation,  as  indicated 
by  the  arrows,  begins.  It  must  be  remembered  that  gravity  is  the  really 
active  force  in  maintaining  this  movement,  because  it  pulls  down  the  denser, 
heavier  air  at  the  cool  margins  with  greater  force  than  the  warm,  expanded, 
light  air  at  the  warm  center.  The  descent  of  the  cool  air  actually  lifts  the 
warm  air. 

The  normal  pressure,  or  weight,  of  the  atmosphere  at  sea  level  is  about 
14.7  pounds  on  each  square  inch  of  surface.  It  is  customary,  however,  to 
express  the  weight  of  the  atmosphere  in  terms  of  inches  of  mercury  instead 
of  in  pounds  and  ounces.  A column  of  air  one  inch  square  from  sea  level  to 
the  top  of  the  atmosphere  will  just  counterbalance  a column  of  mercury 
30.00  inches  high  in  a barometer  tube  of  the  same  size.  We,  therefore,  say 
that  the  normal  pressure  of  the  atmosphere  at  sea  level  is  about  30.00 
inches.  If,  for  any  reason,  the  atmosphere  becomes  heavier  than  normal, 
it  will  raise  the  column  of  mercury  above  the  30  inch  mark,  and  we  say  that 
the  pressure  is  “high.  ’ ’ If  the  atmosphere  becomes  lighter  than  normal,  we 


Weather  Study ' 869 

say  that  the  pressure  is  ‘ ‘low.  ’ ’ So  high  pressure  means  a heavy  atmosphere 
and  low  pressure  a light  atmosphere. 

At  the  beginning  we  assumed  that  the  atmosphere  over  the  broad,  level 
plain  was  quiet  and  that  it  pressed  down  equally  on  every  part  of  the  sur- 
face. We  will  now  assume  that  the  pressure  was  normal,  or  30.00  inches, 
and  note  the  changes  in  pressure  that  result  from  the  interchange  of  air 
between  the  warm  center  and  the  cool  margins.  So  long  as  none  of  the  air 
raised  by  the  expanding  layer  at  the  surface,  moved  away  toward  the  cool 
margins,  no  change  in  pressure  occurred;  but  the  instant  the  air  began  to 
glide  down  the  slopes  away  from  the  warm  center,  *then  the  pressure  at  the 
surface  decreased,  because,  some  air  having  moved  away,  there  was  less  to 
press  down  than  before.  The  pressure  at  the  warm  center,  therefore, 
became  less  than  30.00  inches,  or  in  other  words,  low.  Likewise,  the  air  as 
it  moved  away  from  the  warm  center,  having  lost  much  of  its  heat  during 
its  ascent,  was  gradually  pulled  down  by  gravity  because  of  its  greater 
density,  thus  increasing  the  pressure  over  the  cool  margins.  We,  therefore, 
have  low  pressure  at  the  warm  center,  29.90  inches  and  high  pressure,  30.10 
inches,  at  the  cool  margins.  From  this  illustration  we  obtain  the  six  prin- 
ciples of  convectional  circulation,  viz. : 

1 . Low  pressure  at  warm  center. 

2.  High  pressure  at  cool  margins. 

3 . Ascending  currents  at  warm  center. 

4.  Descending  currents  at  cool  margins. 

5.  Surface  winds  from  high  pressure  to  low  pressure. 

6.  Upper  currents  from  low  pressure  to  high  pressure. 

Now,  we  all  know  that  the  temperature  of  air  is  much  higher  at  the 
equator  than  at  the  poles  and  we  may,  therefore,  let  Fig.  1 represent  a sec-

tion  of  the  atmosphere  along  any  meridian  from  the  north  to  the  south  pole. 
The  equator  would  then  become  the  warm  center  and  the  poles  the  cool 
margins.  We  would  then  expect  to  find  a belt  of  low  pressure  around  the 
world  near  the  equator  because  of  the  high  temperature,  and  high  pressure 
at  the  poles  because  of  the  low  temperature.  We  would,  also,  expect  to 
find  ascending  currents  at  the  equator;  upper  currents  flowing  from  the 
equator  toward  the  poles;  descending  currents  at  the  poles,  and  surface 
winds  blowing  from  the  poles  toward  the  equator.  Let  us  now  test  our 
theory  by  actual  facts  and  see  how  far  they  are  in  accord. 

The  chart,  Fig.  2,  represents  the  normal,  or  average,  pressure  at  sea 
level  for  the  world,  and  if  our  theory  is  in  accord  with  the  facts,  we  should 
find  a belt  of  low  pressure  all  around  the  world  near  the  equator,  with  areas 
of  high  pressure  at  the  poles.  Let  us  examine  the  chart.  Beginning  at  the 
equator,  and  bearing  in  mind  that  the  normal  pfessure  is  about  30.00  inches.

we  find  irregular  lines,  representing  pressures  of  29.90  inches — slightly 
below  normal — around  the  world  on  both  sides  of  the  equator.  Between 
these  lines  we  find  pressure  as  low  as  29.80.  It  is,  therefore,  evident  that 
there  is  a belt  of  low  pressure  around  the  world  near  the  equator,  as  antici- 
pated. Let  us  look  for  the  high  pressure  at  the  poles.  We  have  compara- 
tively few  observations  near  the  poles,  but  the  line  nearest  the  south  pole 
is  marked  29.30  inches,  a surprisingly  low  pressure,  much  lower  even  than 
the  low  belt  at  the  equator,  and  just  the  reverse  of  what  we  expected  to  find. 
When  we  look  at  the  north  pole  we  find  that  the  pressure  is  not  so  low  as  at 
the  south  pole,  but  still  below  normal  and  about  as  low  as  at  the  equator. 
Going  north  and  south  from  the  equator  we  find  that  the  pressure  increases 
gradually  up  to  about  latitude  3 50  in  the  northern  hemisphere  and  to  about 
latitude  30°  in  the  southern,  after  which  it  decreases  toward  the  poles.  So 
there  are  two  well  marked  belts  of  high  pressure  circling  the  globe ; the  one 
about  3 50  north,  and  the  other  about  30°,  south  of  the  equator.  May  it  not 
be  significant  that  these  belts  of  high  pressure  coincide  so  nearly  with  the 
margins,  or  banks,  of  the  air  rivers  mentioned  on  page  867  ? 

Thus  far  our  theory  does  not  accord  very  well  with  the  facts.  True,  we 
found  the  low  pressure  at  the  equator  as  anticipated ; but  we  also  found  low 
pressure  at  the  poles,  where  the  reverse  was  expected ; and  the  high  pressure 
that  we  anticipated  at  the  poles,  we  found  not  far  north  and  south  of  the 
equator.  We  will,  therefore,  have  to  discard  our  theory,  or  reconstruct  it 
to  accord  with  the  facts.  Let  us  reconstruct  Fig.  1 , and  mark  the  pressure 
on  the  line  representing  the  earth’s  surface  along  any  meridian  to  accord 
with  the  facts  as  they  appear  on  Fig.  2. 

The  above  diagram  now  represents  the  true  pressure  along  any  meridian, 
as  determined  by  actual  observations,  and  we  cannot  escape  the  conviction 
that  the  requirements  as  to  temperature  and  pressure  at  the  warm  center 


Weather  Study

are  fulfilled  by  the  high  temperature  and  low  pressure  found  at  the  equator. 
Furthermore,  the  temperature  decreases  north  and  south  from  the  equator, 
and  thus  the  belts  of  high  pressure  near  the  tropics  may  be  taken  to  repre- 
sent the  conditions  at  the  cool  margins.  The  first  and  second  principles  of 
a convectional  circulation,  viz.,  low  pressure  at  the  warm  center  and  a high 
pressure  at  the  cool  margins,  are  thus  fulfilled.  To  satisfy  the  remaining 
conditions,  we  should  find  ascending  currents  near  the  equator,  upper  cur- 
rents flowing  from  the  equator  toward  the  tropical  belts  of  high  pressure, 
descending  currents  at  the  tropics,  and  surface  winds  blowing  from  the 
tropics  toward  the  equator.  Let  us  now  examine  the  surface  winds  of  the 
world  as  illustrated  by  the  diagram  on  page  867. 

On  either  side  of  the  equator  and  blowing  toward  it,  we  find  the  famous 
trade  winds — the  most  constant  and  steady  winds  of  the  world.  Their 
northern  and  southern  margins  coincide  with  the  tropical  belts  of  high  pres- 
sure. They  blow  from  high  pressure  to  low  pressure  and  we  cannot  doubt 
that  they  act  in  obedience  to  the  fifth  principle  of  convectional  circulation. 
From  observation  of  the  lofty,  cirrus  clouds  in  the  trade  wind  belts,  we  have 
abundant  evidence  of  upper  currents,  flowing  away  from  the  equator  toward 
the  tropical  belts  of  high  pressure ; thus  the  sixth  principle  is  satisfied.  The 
torrential  rains  and  violent  thunderstorms,  characteristic  of  the  equatorial 
regions,  bear  evidence  to  the  rapid  cooling  of  the  ascending  currents  near  the 
equator;  while  the  clear,  cool  weather  and  light  winds  of  the  Horse  Lati- 
tudes clearly  indicate  the  presence  of  descending  currents  at  the  tropics. 
Thus,  the  six  principles  of  a convectional  circulation  are  satisfied,  and  the 
evidence  is  conclusive  that  the  trade  winds  form  a part  of  a convectional 
circulation  between  the  tropical  belts  of  high  pressure  and  the  equatorial 
belt  of  low  pressure. 

You  have  doubtless  observed  that  the  trade  winds  do  not  blow  directly 
toward  the  equator  but  are  turned  to  the  west  so  that  they  blow  from  the 
northeast  in  the  northern  hemisphere,  and  from  the  southeast  in  the  south- 
ern. This  peculiarity  is  not  in  strict  accord  with  our  ideas  of  a simple  con- 
vectional circulation  and  suggests,  at  least,  the  presence  of  some  outside 
influence.  If  we  turn  to  Ferre’s  treatise  on  the  winds,  we  find  a demonstra- 
tion of  the  following  principle : a free  moving  body,  such  as  air,  in  moving 
over  the  surface  of  a rotating  globe,  such  as  the  earth,  describes  a path  on 
the  surface  that  turns  to  the  right  of  the  direction  of  motion  in  the  northern 
hemisphere  and  to  the  left  in  the  southern.  The  curvature  of  the  path 
increases  with  the  latitude,  being  zero  at  the  equator  and  greatest  at  the 
poles,  and  is  independent  of  direction.  With  this  in  mind,  if  we  take  posi- 
tion at  the  northern  limit  of  the  trade  winds  in  the  northern  hemisphere  and 
face  the  equator,  (see  p.  867),  we  find  that  the  winds  moving  toward  the 
equator  turn  to  our  right ; likewise,  if  we  face  the  equator  from  the  southern 
limit  of  the  southeast  trades,  we  find  them  turning  to  our  left.  Observa- 
tions of  upper  clouds  in  the  trade  wind  belts  show  that  the  upper  currents 
also  turn  to  the  right  in  the  northern  hemisphere,  and  to  the  left  in  the 
southern.  It  is,  therefore,  clear  that  the  systematic  turning  of  the  trade 
winds  from  the  meridian  is  due  to  the  rotation  of  the  earth.  The  value  of  a 
force  at  various  latitudes  and  for  various  velocities  that  would  cause  a body 
to  turn  away  from  a straight  line,  is  purely  a problem  in  mathematics,  and 
for  the  benefit  of  those  versed  in  the  science  the  formula  is  given.  The 
amount  of  such  a force  is  expressed  by  2 MVW  sin  D,  where  M is  the  mass, 
V the  velocity,  W the  angular  rotation  of  the  earth,  and  D the  latitude.

Not  all  of  us  may  be  able  to  solve  the  problem,  but  we  may  understand 
something  of  the  effect  of  the  rotation  of  the  earth  on  moving  wind  currents. 
It  is  a well-known  principle  of  physics  that  if  a body  be  given  a motion  in 
any  direction,  it  will  continue  to  move  in  a straight  line  by  reason  of  its 
inertia,  without  reference  to  north,  south,  east  or  west.  A personal 
experience  of  this  principle  may  be  gained  in  a street  car  while  it  is  rounding 


a curve. 

In  this  diagram,  we  have  a view  of  the  northern  hemisphere.  The  direc- 
tion of  the  rotation  is  indicated  by  the  curved  arrows  outside  the  circle 
representing  the  equator.  Suppose  that  a wind  starts  from  the  equator, 
moving  along  the  meridian  A directly  toward  the  north  pole.  It  is  clear 
that  it  cannot  continue  to  move  along  the  meridian,  because  the  direction  of 
the  meridian  with  reference  to  space,  is  continually  changing,  and  the  inertia 
of  the  wind  compels  it  to  move  in  a straight  line  without  reference  to  the 
points  of  the  compass.  So  when  the  meridian  A has  been  moved  to  B by 

the  rotation  of  the  earth,  the  wind,  al- 
though it  maintains  its  original  direc- 
tion, no  longer  points  toward  the  pole 
but  to  the  right  of  the  pole.  Like- 
wise, a wind  starting  from  the  pole 
toward  the  equator  also  turns  to  the 
right  of  the  meridians  and  becomes  a 
northeast  wind  as  it  approaches  the 
equator.  A wind  moving  east  or  west, 
also  turns  to  the  right  of  the  parallels 
for  the  same  reason.  So  a wind  start- 
ing out  from  the  equator  with  the  best 
possible  intention  of  hitting  the  pole, 
and  all  the  while  continuing  in  the 
same  straight  line,  will  miss  the  pole  by 
many  miles,  and  always  on  the  right 
side  in  the  northern  and  on  the  left  side 
in  the  southern  hemisphere.  Thus, 
the  oblique  movement  of  both  the  trade  winds  and  the  prevailing  westerlies 
is  accounted  for. 

It  now  remains  to  consider  the  cause  of  the  unexpected  low  pressure 
found  at  the  poles,  and  the  reason  for  the  belts  of  high  pressure  at  the 
tropics.  If  we  refer  to  Fig.  2,  it  is  evident  that  not  all  the  air  that  ascends 
at  the  equator  descends  at  the  tropics,  else  there  would  be  an  absence  of  air 
at  the  higher  latitudes,  which  is  manifestly  not  the  case.  On  the  other 
hand,  it  is  equally  impossible  that  all  the  air  ascending  at  the  equator 
should  move  to  the  poles,  because  the  space  it  could  occupy  decreases 
rapidly  from  a maximum  at  the  equator  to  zero  at  the  poles.  Only  a part 
of  the  air  that  ascends  at  the  equator  is,  therefore,  involved  in  the  trade 
wind  circulation  and  a part  passes  over  the  tropics  and  moves  on  toward 
the  low  pressure  at  the  poles.  Furthermore,  some  of  the  air  that  descends 
at  the  tropics  moves  along  the  surface  toward  the  poles,  obeying  the  law 
that  impels  air  to  move  from  high  pressure  to  low  pressure.  Now  every 
particle  of  air  that  passes  over  the  tropics,  every  particle  that  moves  north- 
ward along  the  surface,  turns  to  the  right  in  the  northern  and  to  the  left  in 
the  southern  hemisphere.  All,  therefore,  miss  the  poles — on  the  right  side 
in  the  northern  and  on  the  left  side  in  the  southern  hemisphere.  The  result

is  that  two  great  whirlpools  develop  in  the  atmosphere;  one  whirling  about 
the  north  and  the  other  whirling  about  the  south  pole.  The  outer  margins 
of  these  whirlpools  coincide  with  the  tropical  belts  of  high  pressure. 

As  an  example  of  a whirlpool  we  may  take  a oasin  having  a vent  at  the 
center  of  the  bottom.  If  the  basin  is  filled  with  water,  the  plug  withdrawn 
and  the  water  given  a slight  rotary  motion,  its  velocity  will  increase  as  it 
approaches  the  center  and  the  rapid  whirling  will  develop  sufficient  cen- 
trifugal force  to  open  an  empty  core.  Those  who  have  visited  the  great 
whirlpool  at  Niagara,  undoubtedly  noticed  that  the  whirling  waters  are 
held  away  from  the  center  and  piled  up  around  the  margins  by  the  centrif- 
ugal force  developed.  Let  us  suppose  that  air  starting  from  the  equator, 
moves  without  friction  or  other  resistances  toward  the  pole.  Its  velocity 
must  increase  as  its  radius  shortens,  because  the  law  of  the  conservation  of 


areas  requires  that  the  radius  must  always  sweep  over  equal  areas  in  a given 
unit  of  time.  (See  law  of  conservation  of  areas.)  At  the  equator,  the  air 
has  an  easterly  motion  equal  to  the  eastward  motion  of  the  earth,  which  is 
1 ,000  miles  per  hour.  At  latitude  6o°  the  radius  will  have  decreased  one- 
half  and  the  velocity,  therefore,  doubled;  but  at  latitude  6o°  the  eastward 
motion  of  the  earth  is  only  500  miles  per  hour,  so  the  air  would  be  moving 
1500  miles  per  hour  faster  than  the  earth.  At  a distance  of  40  miles  from 
the  pole  the  wind  would  attain  an  easterly  velocity  of  100,000  miles  per 
hour,  and  moving  on  so  short  a radius  would  develop  sufficient  centrifugal 
force  to  hold  all  the  air  away  from  the  pole  and  thus  form  a vacuum.  That 
the  supposed  case  of  no  friction  is  far  from  the  truth  is  evidenced  by  the 
fact  that  the  pressure  at  the  north  pole  is  but  little  less  than  at  the  equator ; 
but  the  centrifugal  force  developed  by  the  gyration  winds,  in  thus  with- 
drawing the  air  from  the  poles  and  piling  it  up  at  the  tropics,  may  be  fairly 
taken  as  sufficient  cause  for  the  low  pressure  found  at  the  poles  and  the 
belts  of  high  pressure  at  the  tropics. 

The  questions  that  remain  to  be  considered  are : ( 1 ) the  low  pressure  at 

the  south  pole  as  compared  with  the  pressure  at  the  north  pole  and  (2)  the 


874 


Handbook  of  Nature-Study 


unequal  distance  of  the  tropical  belts  of  high  pressure  from  the  equator. 
These  questions  may  be  considered  together. 

It  is  to  be  remembered  that  the  southern  hemisphere  is  the  water  hemi- 
sphere, and  that  the  prevailing  westerlies,  in  gliding  over  the  smooth  water 
surface,  are  but  little  retarded  by  friction  and,  therefore,  attain  a higher 
velocity  than  the  corresponding  winds  of  the  northern  hemisphere,  where 
the  rougher  surface  materially  retards  their  movement.  As  a consequence, 
the  circumpolar  whirl  of  the  southern  hemisphere  is  stronger,  and  develops  a 
greater  centrifugal  force,  thus  holding  a larger  quantity  of  air  away  from  the 
south  pole  and  reducing  the  pressure  to  a greater  degree  than  is  brought 
about  by  the  weaker  winds  of  the  northern  hemisphere. 

Since  the  circumpolar  whirl  of  the  southern  hemisphere  is  the  stronger 
of  the  two,  it  withdraws  the  air  to  a greater  distance  from  the  pole  than  does 
its  weaker  counterpart  of  the  northern  hemisphere,  and  piles  it  up  in  the 
tropical  belt  of  high  pressure  about  five  degrees  nearer  the  equator  than 
does  the  weaker  forces  of  the  northern  hemisphere. 

Storms 

Having  gained  a comprehensive  view  of  the 
general,  planetary  wind  system,  we  may  now 
undertake  the  study  of  local  disturbances  that 
arise  within  the  general  circulation  and  are 
known  as  “storms.” 

Storms  are  simply  eddies  in  the  atmosphere. 
They  may  be  compared  to  the  eddies  that  are 
often  seen  floating  along  with  the  current  of  a 
river  or  creek.  In  these  eddies  the  water  is 
seen  to  move  rapidly  around  a central  vertex, 
developing  sufficient  centrifugal  force  to  hold 
some  of  the  water  away  from  the  center,  thus 
forming  a well  marked  depression,  frequently 
of  considerable  depth.  The  whole  circulation 
of  the  eddy  is  quite  independent  of  the  current 
of  the  stream  which  carries  it  along  its  course,  and  while  its  general  direction 
and  velocity  of  movement  coincide  with  that  of  the  current,  there  are  times 
when  it  will  be  seen  to  move  quickly  from  side  to  side  and  again  when  it  will 
remain  nearly  stationary  for  a time  or  take  on  a rapid  movement. 

The  eddies  or  storms  in  the  atmosphere  act  in  much  the  same  way. 
They  are  carried  along  by  the  general  currents  of  the  river  of  air  in  which 
they  exist.  Their  general  direction  coincides  with  the  direction  of  the 
current  in  which  they  are  floating,  and  their  rate  of  movement  conforms  in 
a general  way  to  its  velocity ; but  like  the  eddies  in  the  river,  they  do  not 
always  move  in  straight  lines  nor  at  a uniform  rate  of  speed. 

There  is  one  important  respect  in  which  the  eddies  in  the  air  differ  from 
eddies  in  water.  The  water  eddy  may  revolve  in  either  direction,  depend- 
ing upon  the  direction  in  which  the  initial  force  was  applied,  but  the  storm 
eddies  in  the  atmosphere  always  revolve  counter-clockwise  in  the  northern 
hemisphere,  and  clockwise  in  the  southern. 

This  is  due  to  the  deflecting  force  of  the  earth’s  rotation,  which  is  fully 
explained  on  page  872.

Weather  Maps 

A weather  map  is  a sort  of  flashlight  photograph 
of  a section  of  the  bottom  of  one  or  more  of  these 
great  rivers  of  air.  It  brings  into  view  the  whole 
meteorological  situation  over  a large  territory  at  a 
given  instant  of  time ; and,  while  a single  map  con- 
veys no  indication  of  the  movements  continually 
taking  place  in  the  atmosphere,  a series  of  maps,  like 
a moving  picture,  shows  not  only  the  whirling 
eddies,  the  hurrying  clouds  and  the  fast-moving 
winds,  but  the  ceaseless  on-flow  of  the  great  river  of 
air  in  which  they  float.  Our  present  knowledge  of 
the  movements  of  the  atmosphere  has  been  gained 
chiefly  from  a study  of  weather  maps ; they  form  the  basis  of  the  modern 
system  of  weather  forecasting,  and  their  careful  study  is  essential  to  any 
adequate  understanding  of  the  problems  presented  by  the  atmosphere. 
(See  pages  884-885.) 

The  Principles  of  Weather  Forecasting 
The  forecasting  of  the  weather  has  been 
made  possible  by  the  electric  telegraph.  It  is 
based  upon  a perfectly  simple,  rational  process 
constantly  employed  in  everyday  affairs.  We 
go  to  a railway  station  and  ask  the  operator 
about  a certain  train.  He  tells  us  that  it  will 
arrive  in,  an  hour.  We  accept  his  statement 
without  question,  because  we  are  confident  that 
he  knows  the  speed  at  which  the  train  is  ap- 
proaching, a few  clicks  of  his  telegraph  instru- 
ment has  told  him  just  where  it  is  and  the  time  it 
will  arrive,  barring  accidents,  is  a simple  calcula- 
tion. Information  of  coming  weather  changes  Snow  crystal. 

are  obtained  in  a similar  manner.  Although  Photomicrograph  by 

storms  do  not  run  on  steel  rails  like  a train,  w.  a.  Bentley, 

nevertheless  their  movements  may  be  foreseen  with  a reasonable  degree  of 
accuracy,  depending  chiefly  upon  the  size  of  the  territory  from  which  tele- 
graphic reports  are  received  and  the  experience  and  skill  of  the  forecaster. 
As  a rule,  the  larger  the  territory  brought  under  observation,  especially  in 
its  longitudinal  extent  (the  general  currents  carry  storms  of  the  middle 
latitudes  eastward  around  the  world  and  those  of  the  tropics  westward) , the 
earlier  advancing  changes  may  be  recognized  and  the  more  accurately  their 
movements  foreseen. 


Forecasts  Based  on  Weather  Maps 

The  forecasts  issued  by  the  United  States  Weather  Bureau  are  based  on 
weather  maps,  prepared  from  observations  taken  at  8 a.  m.  and  8 p.  m.  at 
about  200  observatories.  In  addition  to  the  reports  received  by  telegraph 
by  the  Central  Office  at  Washington,  the  several  forecast  centers  and  other 
designated  stations  from  observatories  or  stations  in  the  United  States,  a 
system  of  interchange  with  Canada,  Mexico,  the  West  Indies  and  other 
island  outposts  in  the  Atlantic  and  Pacific  gives  to  the  forecaster  two  daily 
photographs  of  the  weather  conditions  over  a territory  embracing  nearly

at  once  upon  the  weather  map.  If  it  be  a West  Indies  hurricane  or  other 
destructive  storm,  its  character  is  recognized  instantly,  its  rate  and  direc- 
tion determined  and  information  of  the  probable  time  of  its  arrival  sent  to 
those  places  that  lie  in  its  path.  The  method  is  perfectly  simple.  Anyone 
with  a weather  map  and  a little  experience  can  forecast  the  weather  with 
some  degree  of  accuracy,  or,  at  least,  gain  an  intelligent  understanding  of 
the  conditions  upon  which  the  forecasts  that  accompany  the  map  are  based. 

Maps,  Where  Published  and  How  Obtained 

Weather  maps  are  published  in  many  daily  papers,  and  in  somewhat 
larger  form  and  more  in  detail,  at  many  Weather  Bureau  stations.  They 
may  usually  be  obtained  for  school  use  by  applying  to  the  nearest  Weather 
Bureau  station  or  to  the  Chief  of  the  Weather  Bureau  at  Washington,  D.  C. 

The  forecasts  that  accompany  the  maps  are  simply  an  expression  on  the 
part  of  the  official  forecaster  as  to  the  weather  changes  he  expects  to  occur 
in  various  parts  of  the  country  within  the  time  specified,  usually  within  36 
to  48  hours.  His  opinion  is  based  upon  the  conditions  shown  by  the  map. 
He  has  no  secret  source  of  information.  You  may  accept  his  conclusions, 
or,  if  in  your  opinion  they  are  not  justified,  you  have  all  the  information 
necessary  to  make  a forecast  for  yourself.  Weather  maps  are  published  so 
extensively  with  a view  to  thus  stimulating  an  intelligent  interest  in  the 
problem  of  weather  forecasting,  and  also  that  one  may  see  at  a glance 
what  the  temperature,  rainfall,  wind  and  weather  is  in  any  part  of  the 
country  in  which  he  may  be  interested.  The  friends  of  the  weather  service 
are  those  who  best  understand  its  work. 


The  Value  of  the  Weather  Service 
No  one  knows  so  well  as  the  forecaster  that  the 
changes  that  appear  most  certain  to  come  some- 
times fail,  or  come  too  late;  but  taking  all  in  all, 
about  85  out  of  100  forecasts  are  correct.  Of 
those  that  fail,  probably  not  more  than  three  of 
four  per  cent,  fail  because  the  changes  come 
unannounced.  Most  forecasters  predict  too 
much,  and  their  forecasts  fail  because  the  expected 
changes  come  after  the  time  specified  or  not  at  all. 
It  is  fortunate  that  this  is  so ; for  it  is  better  to  be 
prepared  for  the  change  though  it  be  late  in  co  m±ng 
than  to  have  it  come  without  warning. 

The  value  of  the  weather  service  to  the  agriculture  and  commerce  of  the 
United  States  cannot  be  questioned  seriously.  That  the  appropriations 
for  its  support  have  been  increased  year  by  year  from  $1,500  in  1871  to 
nearly  $1,500,000  in  1910  is  evidence  of  its  value  and  efficiency.  A con- 
servative estimate  places  the  value  of  property  saved  by  the  warnings  issued 
by  the  Weather  Bureau  at  $30,000,000  annually.

LESSON  CCXXI1 

Experiments  to  Show  Air  Pressure 

Leading  thought — The  air  presses  equally 
in  all  directions. 

Experiment  1 — To  show  that  air  presses 
upward — Fill  a tumbler  which  has  an 
unbroken  edge  as  full  of  water  as  possible. 

Take  a piece  of  writing  paper  and  cover  the 
tumbler,  pressing  the  paper  down  firmly 
upon  the  edge  of  the  glass.  Turn  the  glass 
bottom  side  up  and  ask  why  the  water  does 
not  flow  out.  Allow  a little  air  to  enter; 
what  happens?  Why?  Turn  the  glass 
filled  with  water  and  covered  with  paper 
sidewise ; does  the  water  flow  out  ? If  not, 
why? 

Experiment  2 — To  show  that  air  passes 
downward — Ask  some  of  the  boys  of  the 
class  to  make  what  they  call  a sucker. 

This  is  a piece  of  leather  a few  inches 
across.  Through  its  center  a string  is 
drawn  which  fits  very  closely  into  the  leather  and  is  held  in  place  by  a very 
flat  knot  on  the  lower  side.  Dampen  the  leather  and  press  it  against  any 
flat  surface,  and  try  to  pull  it  off.  If  possible,  place  the  sucker  on  a flat 
stone  and  see  how  heavy  a stone  can  be  lifted  by  the  sucker.  Ask  why  a 
sucker  clings  so  to  the  flat  surface.  If  a little  air  is  allowed  to  get  between 
the  sucker  and  the  stone,  what  happens  ? Why  ? 

Hints  to  the  teacher  regarding  the  Experiments — The  water  is  kept  in  the 
tumbler  in  Experiment  1 by  the  pressure  of  the  atmosphere  against  the 
paper.  If  the  tumbler  is  tipped  to  one  side  the  water  still  remains  in  the 
glass,  which  shows  that  the  air  is  pressing  against  the  paper  from  the  side 
with  sufficient  force  to  restrain  the  water,  and  if  the  tumbler  is  tipped 
bottom  side  up  it  shows  the  air  is  pressing  upward  with  sufficient  force  to 
keep  the  water  within  the  glass. 

In  the  case  of  Experiment  2 , we  know  that  the  leather  pressing  upon  the 
floor  or  on  the  stone  is  not  in  itself  adhesive,  but  it  is  made  wet  simply  so 
that  it  shall  press  against  the  smooth  surface  more  closely.  The  reason 
why  we  cannot  pull  it  off  is  that  the  air  is  pressing  down  upon  it  with  the 
force  of  about  fifteen  pounds  to  the  square  inch.  If  the  experiment  is  per- 
formed at  sea  level,  we  should  be  able  to  lift  by  the  string  of  the  sucker  a 
stone  weighing  fifteen  pounds.  The  reason  why  the  water  falls  out  of  the 
tumbler  after  a little  air  is  let  beneath  the  paper,  is  that  then  the  air  is 
pressing  on  both  sides  of  the  paper;  and  the  reason  why  the  sucker  will  not 
hold  if  there  is  any  air  between  it  and  the  stone,  is  because  the  air  is  pressing 
in  both  directions  upon  it.

LESSON  CCXXIII 
The  Barometer 

Leading  thought — The  weight  of  our 
atmosphere  balances  a column  of  mercury 
about  thirty  inches  high,  and  is  equal  to 
about  fifteen  pounds  to  the  square  inch. 
This  pressure  varies  from  day  to  day,  and 
becomes  less  as  the  height  of  the  place 
increases.  The  barometer  is  an  instru- 
ment for  measuring  the  atmospheric  pres- 
sure. It  is  used  in  finding  the  height  of 
mountains,  and,  to  a certain  extent,  it 
indicates  changes  of  the  weather. 

Method — A glass  tube  about  36  inches 
long,  closed  at  one  end;  a little  glass 
funnel  about  an  inch  in  diameter  at  the  top ; 
a small  cup — a bird’s  bathtub  is  a good  size 
since  it  allows  plenty  of  room  for  the 
fingers ; mercury  enough  to  fill  the  tube  and 
have  the  mercury  an  inch  or  more  deep  in  the  cup.  Be  careful  not  to 
spill  the  mercury  in  the  following  process,  or  you  will  be  as  badly  off  as 
old  Sisyphus  with  his  rolling  stone. 

Set  the  closed  end  of  the  tube  in  the  cup  so  that 
any  spilled  mercury  will  not  be  lost ; with  the  help 
of  the  funnel  slowly  and  carefully  fill  the  tube  clear 
to  the  top  with  the  mercury ; empty  the  rest  of  the 
mercury  into  the  cup ; place  the  end  of  one  of  the 
fingers  of  the  left  hand  tightly  over  the  open  end  of 
the  tube  and  keep  it  there;  with  the  right  hand 
invert  the  tube,  keeping  the  end  closed  with  the 
finger,  and  place  the  hand,  finger  and  all,  beneath 
the  mercury  in  the  cup  then  remove  the  finger, 
keeping  the  open  end  of  the  tube  all  the  time  below 
the  surface  of  the  mercury.  When  the  mercury  has 
ceased  to  fall  measure  the  distance  from  the  surface 
in  the  cup  to  the  top  of  the  mercury  in  the  tube. 

Observations — 1.  How  high  is  the  column  of 
mercury  in  the  tube? 

2 . What  keeps  the  mercury  in  the  tube  ? Place 
the  cup  and  the  tube  on  a table  in  the  corner  of  the 
room,  place  behind  the  tube  a yardstick,  and  note 
whether  the  column  of  mercury  is  the  same  height 
day  after  day.  If  it  varies,  why  ? 

3.  Would  the  mercury  column  be  as  high  in  the  tube  if  it  were  placed 
on  top  of  a mountain  as  it  would  at  the  foot  ? Why  ?

HOW  TO  READ  WEATHER  MAPS 
Teacher's  Story 

Weather  maps  may  be  obtained  by 
writing  to  the  nearest  Weather  Station, 
or  by  writing  to  the  Chief  of  the  Weather 
Bureau,  Dr.  Willis  L.  Moore,  Washing- 
ton, D.  C.,  stating  that  you  wish  to  post 
the  maps  in  a public  place.  A supply 
of  maps  for  three  successive  days  for  use 
in  these  lessons  may  be  obtained  at  20 
cents  per  hundred.  Sometimes  they  are 
sent  free,  if  it  is  stated  that  they  are 
to  be  used  for  school  purposes. 

The  words  isobar  and  isotherm  have 
been  bogies  which  have  frightened 
many  a teacher  from  undertaking  to 
teach  about  weather  maps,  and  yet  how 
simple  are  the  meaning  of  these  two 
words.  Isobar  is  made  up  of  two 
Greek  words,  isos  meaning  equal  and 
baros  meaning  weight.  Therefore,  an 
isobar  means  equal  weight,  and  on  a map 
one  of  these  continuous  lines  means  that, 
wherever  it  passes,  the  atmosphere  there 
has  equal  weight  and  the  barometer 
stands  at  equal  height.  The  isobar  of 
30  means  that  the  mercury  in  the  bar- 
ometer stands  30  inches  in  height  in 
all  the  regions  where  that  line  passes. 

“Isotherm”  comes  from  the  two  Greek  words,  isos  meaning  equal  and 
iherme  meaning  heat.  Therefore,  on  the  map  the  dotted  lines  show  the 
region  where  the  temperature  is  the  same.  If  at  the  end  of  the  dotted  line 
you  find  60  it  means  that,  wherever  that  line  passes,  the  thermometer 
stands  at  60  degrees. 

Many  of  the  “highs”  and  “lows”  enter  the  United  States  from  the 
Pacific  Ocean  about  the  latitude  of  Washington  State  or  southwest  British 
Columbia.  They  follow  one  another  alternately,  crossing  the  continent  in 
the  general  direction  of  west  to  east  in  a path  which  curves  somewhat  to  the 
north,  and  they  leave  the  United  States  in  the  latitude  of  Maine  or  New 
Brunswick.  If  they  enter  by  way  of  lower  California,  they  pass  over  to  the 
Atlantic  Ocean  farther  south.  The  time  for  the  passage  of  a high  or  low 
across  the  continent  averages  about  three  and  one-half  days,  sometimes  a 
little  more.  These  areas  are  usually  more  marked  in  winter,  and  wind 
storms  are  more  marked  and  more  regular. 

A low  area  is  called  a cyclone  and  a high  area  an  anti-cyclone.  The 
destructive  winds,  popularly  called  cyclones,  which  occur  in  certain  regions, 
should  be  called  tornadoes  instead,  although  in  fact  they  are  simply  small 
and  violent  cyclones.  But  a cyclone,  when  used  in  a meteorological  sense, 
extends  over  thousands  of  square  miles  and  is  not  violent ; while  a tornado 
may  be  only  a few  rods  in  diameter  and  be  very  destructive.  The  little 
whirlwinds  which  lift  the  dust  in  the  roads  are  rotary  winds  also,  but  merely 
the  eddies  of  a gentle  wind. 


88o 


Handbook  of  Nature-Study 


In  a cyclone  or  “low,”  and  also  in  a tornado,  the  air  blows  from  all  sides 
spirally  inward  toward  the  center  where  there  is  a column  of  ascending  air. 

In  an  anti-cyclone  or  “high”  the  air  blows  outward  in  every  direction 
in  curved  lines  from  a column  of  descending  air. 


In  the  above  map,  the  curved  lines  are  isobars;  the  line  of  crosses  from 
A to  B indicates  the  course  of  the  storm ; the  arrows  indicate  the  direction 
of  the  wind,  note  that  it  is  moving  counter-clockwise  around  the  area  of 
low  pressure;  the  shaded  area  indicates  the  region  where  it  is  raining  or 
snowing;  note  that  this  is  the  area  where  the  warm,  moist  air  from  the 
Gulf  and  the  Ocean  meets  the  colder  air  of  the  North. 

The  weather  conditions  during  the  passage  of  a cyclone  are  briefly  as 
follows:  Small,  changing  wisps  of  cirrus  clouds  appear  about  24  hours 
before  rain ; these  gradually  become  larger  and  cover  the  whole  sky,  making 
a nimbus  cloud.  The  wind  changes  from  northeast  to  east  or  southeast  to 
south.  The  barometer  falls ; the  thermometer  rises,  that  is,  air  pressure  is 
less  to  the  square  inch,  and  the  temperature  of  the  atmosphere  is  warmer. 
Rain  begins  and  falls  for  a time,  varying  from  an  hour  to  a day  or  more. 
After  the  rain  there  appear  breaks  in  the  great  nimbus  clouds  and  finally  the 
blue  sky  conquers  until  there  are  only  a few  or  no  clouds.  The  wind 
changes  to  southwest  and  west;  the  barometer  rises,  the  temperature  falls. 
The  rain  ceases,  the  sun  shines  out  brightly.  The  low  has  passed  and  the 
high  is  approaching  to  last  about  three  days.

Explanation  of  Storm  and  Hurricane  Signals 

Storm  warning — A red  flag  with  a black  center  indicates  that  a storm  of  marked  violence  is  expected. 

The  pennants  displayed  with  the  flags  indicate  the  direction  of  the  wind;  red,  easterly  (from  north- 
east to  south) ; white  (westerly  from  southwest  to  north).  The  pennant  above  the  flag  indicates  that 
the  wind  is  expected  to  blow  from  the  northerly  quadrants;  below  from  the  southerly  quadrants. 

By  night  a red  light  indicates  easterly  winds  and  a white  light  below  a red  light  westerly  winds. 

Hurricane  warning — Two  red  flags  with  black  centers  displayed  one  above  the  other  indicates  the 
expected  approach  of  a tropical  hurricane  or  one  of  those  extremely  severe  and  dangerous  storms  which 
occasionally  move  across  the  Lakes  and  northern  Atlantic  coast. 

No  night  hurricane  warnings  are  displayed.

LESSON  CCXXIV 
How  to  Read  Weather  Maps 

Leading  thought — Weather  maps  are  made  with  great  care  by  the 
Weather  Bureau  experts.  Each  map  is  the  result  of  many  telegraphic 
communications  from  all  parts  of  the  country.  Every  intelligent  person 
should  be  able  to  understand  the  weather  maps. 

Method — Get  several  weather  maps  of  the  nearest  Weather  Bureau  Sta- 
tion. They  should  be  maps  for  successive  days,  and  there  should  be 
enough  so  that  each  pupil  can  have  three  maps,  showing  the  weather  condi- 
tions for  three  successive  days. 

Observations — i . T ake  the  map  of  the  earliest  date  of  the  three.  Where 
was  your  map  used?  What  is  its  date  ? How  many  kinds  of  lines  are  there 
on  your  map  ? Are  there  explanatory  notes  on  the  lower  left-hand  comer  of 
your  map  ? Explain  what  the  continuous  lines  mean.  Find  an  isobar  of 
30 ; to  what  does  this  figure  refer?  Find  all  the  towns  on  your  map  where 
the  barometer  stands  at  30  inches.  Is  there  more  than  one  isobar  on  your 
map  where  the  barometer  stands  at  30? 

2 . Where  is  the  greatest  air  pressure  on  your  map  ? How  high  does  the 
barometer  stand  there?  How  are  the  isobars  arranged  with  reference  to 
this  region  ? What  word  is  printed  in  the  center  of  this  series  of  isobars  ? 

3 . What  do  the  arrows  indicate  ? What  do  the  circles  attached  to  the 
arrows  indicate? 

4.  In  general,  what  is  the  direction  of  the  winds  with  reference  to  this 
high  center? 

5 . Is  the  air  rising  or  sinking  at  the  center  of  this  area  ? If  the  wind  is 
blowing  in  all  directions  from  a center  marked  high,  what  sort  of  weather 
must  the  places  just  east  of  the  high  be  having?  Do  the  arrows  with  their 
circles  indicate  this? 

6.  Find  a center  marked  low.  How  high  does  the  barometer  stand 
there?  Does  the  air  pressure  increase  or  diminish  away  from  the  center 
marked  low,  as  indicated  by  the  isobars  ? Do  the  winds  blow  toward  this 
center  or  away  from  it  ? 

7 . What  must  the  weather  in  the  region  just  east  of  the  low  be  ? Why  ? 
Do  the  arrows  and  circles  indicate  this  ? 

8.  Is  there  a shaded  area  on  your  map  ? If  so,  what  does  this  show  ? 

9.  Compare  the  map  of  the  next  date  with  the  one  you  have  just 
studied.  Are  the  highs  and  lows  in  just  the  same  position  that  they  were 
the  day  before  ? Where  are  the  centers  high  and  low  now  ? In  what  direc- 
tions have  they  moved  ? 

10.  Look  at  the  third  map  and  compare  the  three  maps.  Where  do  the 
high  and  low  centers  seem  to  have  originated  ? How  long  does  it  take  a high 
or  low  to  cross  the  United  States  ? How  far  north  and  south  does  a high  or 
low,  with  all  its  isobars,  extend? 

11.  What  do  the  dotted  lines  on  your  map  mean?  Do  they  follow 
exactly  the  isobars  ? 

12.  What  is  the  greatest  isotherm  on  your  map?  Through  or  near 
what  towns  does  it  pass  ? 

13 . Do  the  regions  of  high  air  pressure  have  the  highest  temperature  or 
the  lowest  ? Do  high  temperatures  accompany  low  pressures?  Why  ? 

14.  What  is  the  condition  of  the  sky  just  east  of  a low  center?  What 
is  its  condition  just  west  of  low? 


Weather  Study 


88S 


15.  If  the  isobars  are  near  together  in  a low,  it  means  that  the  wind 
is  moving  rather  fast  and  that  there  will  be  a well  marked  storm.  Look  at 
the  column  giving  wind  velocity.  W as  the  wind  blowing  toward  the  center 
of  the  low  on  the  map?  If  so,  does  that  mean  it  is  coming  fast  or  slow? 
How  does  this  fact  correspond  with  the  indications  shown  by  the  distance 
between  the  isobars  ? 

16.  Describe  the  weather  accompanying  the  approach  and  passage  of  a 
low  in  the  region  where  your  town  is  situated  ? What  sort  of  clouds  would 
you  have,  what  winds,  what  change  of  the  barometer  and  thermometer? 

How  to  Find  the  General  Direction  and  Average  Rate  of  Motion  of 
Highs  and  Lows 

Observations — 1.  On  the  first  map  of  the  series  of  three  given,  put  an  X 
in  red  pencil  or  crayon  at  the  center  of  the  high  and  a blue  one  at  the  center 
of  the  low;  or  if  you  do  not  have  the  colored  pencils,  use  some  other  dis- 
tinguishing marks  for  the  two.  If  there  are  two  highs  and  two  lows  use  a 
different  mark  for  each  one. 

2.  Mark  the  position  of  each  center  on  this  map  for  the  following  day 
with  the  same  mark  that  you  first  used  for  that  area.  Do  this  for  each  of 
the  highs  and  lows  until  it  leaves  the  map  or  until  your  maps  have  been 
used.  All  the  marks  of  one  kind  can  be  joined  by  a line,  using  a red  line  for 
the  red  marks  and  a blue  line  for  the  blue  marks. 

3 . What  do  you  find  to  be  the  general  direction  of  the  movement  of  the 
highs  and  lows? 

4.  Examine  the  scale  marked  statute  miles  at  the  bottom  of  the  map. 
How  many  miles  are  represented  by  one  inch  on  the  scale  ? 

5 . With  your  ruler  find  out  how  many  miles  one  area  of  high  or  low  has 
moved  in  twenty-four  hours ; in  three  days.  Divide  the  distance  which  the 
area  has  moved  in  three  days  by  three  and  this  will  give  the  average  velocity 
for  one  day. 

6.  In  the  same  way  find  the  average  veolcity  of  each  of  the  areas  on 
your  map  for  three  days  and  write  down  all  your  answers.  From  all  your 
results  find  the  average  weekly  velocity;  that  is,  how  many  miles  per  hour 
and  the  general  direction  which  has  characterized  the  movement  of  the  high 
and  low  areas.

How  to  Keep  a Daily  Weather  Map 

The  pupils  should  keep  a daily  weather  map  record  for  at  least  six 
months.  The  observations  should  be  made  twice  each  day  and  always  at 
the  same  hours.  While  it  would  be  better  if  these  records  could  be  made  at 
8 o’clock  in  the  morning  and  again  at  8 o’clock  in  the  evening,  this  is  hardly 
practicable  and  they  should,  therefore,  be  made  at  9 o’clock  and  at  4.  The 
accompanying  chart  may  be  drawn  enlarged.  Sheets  of  manila  paper  are 
often  used,  so  that  one  chart  may  cover  the  observations  for  a month. 

Few  schools  are  able  to  have  a working  barometer,  but  observations  of 
temperature  and  sky  should  be  made  in  every  school.  Almost  any  boy  can 
make  a weather  vane,  which  should  be  placed  on  a high  building  or  tree 
where  the  wind  will  not  be  deflected  from  its  true  direction  when  striking  it. 
A thermometer  should  be  placed  on  the  north  side  of  a post  and  on  a level

with  the  eyes ; it  should  not  be  hung  to  a building,  as  the  temperature  of  the 
building  might  affect  it. 

The  direction  of  the  wind  and  the  cloudiness  of  the  day  may  be  indicated 
on  the  chart,  as  it  is  on  the  weather  maps,  by  a circle  attached  to  an  arrow 
which  points  in  the  direction  in  which  the  wind  is  blowing.

“ Though  I know  not  what  you  are , twinkle,  twinkle  liltle  star  .” 

THE  STORY  OF  THE  STARS 
Teacher's  Story 

tlWhy  did  not  somebody  teach  me  the  constellations  and  make  me  at  home  in  the  starry 
heavens,  which  are  always  overhead,  and  which  I don't  half  know  to  this  day." 

—Thomas  Carlyle. 

For  many  reasons  aside  from  the  mere  knowledge  acquired,  children 
should  be  taught  to  know  something  of  the  stars.  It  is  an  investment  for 
future  years;  the  stars  are  a constant  reminder  to  us  of  the  thousands  of 
worlds  outside  our  own,  and  looking  at  them  intelligently,  lifts  us  out  of 
ourselves  in  wonder  and  admiration  for  the  infinity  of  the  universe,  and 
serves  to  make  our  own  cares  and  trials  seem  trivial.  The  author  has  not  a 
wide  knowledge  of  the  stars;  a dozen  constellations  were  taught  to  her  as  a 
little  child  by  her  mother,  who  loved  the  sky  as  well  as  the  earth;  but 
perhaps  nothing  she  has  ever  learned  has  been  to  her  such  a constant  source 
of  satisfaction  and  pleasure  as  this  ability  to  call  a few  stars  by  the  names 
they  have  borne  since  the  men  of  ancient  times  first  mapped  the  heavens. 
It  has  given  her  a sense  of  friendliness  with  the  night  sky,  that  can  only  be 
understood  by  those  who  have  had  a similar  experience. 

There  are  three  ways  in  which  the  mysteries  of  the  skies  are  made  plain 
to  us:  First,  by  the  telescope;  second,  by  geometry,  trigonometry  and 
calculations — a proof  that  mathematics  is  even  more  of  a heavenly  than  an 
earthly  science;  and  third,  by  the  use  of  the  spectroscope,  which  can  only 
be  understood  after  we  study  physics.  It  is  an  instrument  which  tells  us, 
by  analyzing  the  light  of  the  stars,  what  chemical  elements  compose  them ; 
and  also,  by  the  means  of  the  light,  it  estimates  the  rate  at  which  the  stars 
are  moving  and  the  direction  of  their  motion  toward  or  away  from  us. 

Thus,  we  have  learned  many  things  about  the  stars ; we  know  that  every 
shining  star  is  a great  blazing  sun,  and  there  is  no  reason  to  doubt  that 
many  of  these  suns  have  worlds,  like  the  earth,  spinning  around  them 
although,  of  course,  so  far  away  as  to  be  invisible  to  us ; for  our  world  could 
not  be  seen  at  all  from  even  the  nearest  star.  We  also  know  that  many  of 


888 


Handbook  of  Nature-Study 


the  stars  which  seem  single  to  us  are  really  double — made  up  of  two  vast 
suns  swinging  around  a common  center;  and  although  they  may  be  mil- 
lions of  miles  apart,  they  are  so  far  away  that  they  seem  to  us  as  one  star. 
The  telescope  reveals  many  of  these  double  stars  and  shows  that  they  circle 
around  their  orbits  in  various  periods  of  time,  the  most  rapid  making  the 
circle  in  five  years,  another  in  sixteen  years,  another  in  forty-six  years; 
while  there  is  at  least  one  lazy  pair  which  seems  to  require  fully  sixteen 
hundred  years  to  complete  their  circle.  And  the  spectroscope  has  revealed 
to  us  that  many  of  the  stars  which  seem  single  through  the  largest  telescope 
are  really  double,  and  some  of  these  great  suns  race  around  each  other  in  the 
period  of  a few  hours,  which  is  a rate  of  speed  we  could  hardly  imagine. 

Astronomers  have  been  able  to  measure  the  distance  from  us  to  many  of 
the  stars,  but  when  this  distance  is  expressed  in  miles  it  is  too  much  for  us  to 
grasp.  Thus,  they  have  come  to  measure  heavenly  distance  in  terms  of  the 
rate  at  which  light  travels,  which  is  186,400  miles  per  second  or  about  six 
trillions  of  miles  per  year ; this  distance  is  called  a light-year.  Light  reaches 
us  from  the  sun  in  about  eight  minutes,  but  it  takes  more  than  four  years  for 
a ray  to  reach  us  from  the  nearest  star.  It  adds  new  interest  to  the  Pole- 
star  to  know  that  the  light  which  reaches  our  eyes  left  that  star  almost  half 
a century  ago,  and  that  the  light  we  get  from  the  Pleiades  may  have  started 
on  its  journey  before  America  was  discovered.  Most  of  the  stars  are  so  far 
away  that  we  cannot  measure  the  distance. 

Although  stars  seem  stationary,  they  are  all  moving  through  space 
just  as  our  own  sun  is  doing;  but  the  stars  are  so  far  away  that  even  if 
one  moved  a million  miles  a day,  it  would  require  years  of  observation 
to  detect  that  it  moved  at  all,  unless  it  was  moving  toward  or  away  from 
us.  We  know  the  rate  of  movement  of  some  stars  but  have  no  idea  of 
their  goal,  nor  do  we  know  where  our  sun  is  dragging  us  at  the  rate  of 
nearly  800  miles  a minute;  all  we  know  is  that  each  star  is  going  some- 
where and  attending  strictly  to  its  own  business. 

The  spectroscope  reveals  the  life  cycle  of  stars;  when  young  they  are 
composed  of  thin  gases  shining  red  and  are  giant  stars;  when  older  and 
more  condensed  they  shine  yellow,  when  still  more  condensed  they  shine 
white  and  blue,  which  marks  middle  life.  With  old  age  they  contract 
and  begin  to  cool;  after  this  they  shine  white,  then  yellow,  then  red,  and 
then  become  dark,  cold,  dead  stars.  Red  is  a sign  of  infancy  and  of  old 
age;  but  the  young  red  stars  are  giants  and  the  old  red  stars  are  dwarfs. 
The  spectroscope  reveals  many  dark  stars  in  our  skies ; but  they  are  not 
all  dead  suns  for  some  of  them  may  still  be  unborn.  If  one  of  these  dark 
stars  should  approach  another  star,  the  force  developed  would  shatter  it 
into  glowing,  gaseous  atoms  and  it  would  finally  become  a shining  star. 

Scattered  through  the  skies  are  masses  of  misty  light  called  nebulae, 
meaning  “clouds.”  They  are  vast  gaseous  bodies  of  different  shapes,  and 
are  classified  as  irregular,  globular,  ringed  and  spiral.  While  some  are 
dark,  many  are  made  up  of  glowing  gases,  largely  hydrogen  and  helium, 
and  each  nebula  keeps  its  own  place  in  the  heavens  like  a star,  and  moves 
through  space  like  a star.  The  spiral  nebulae  are  at  least  100,000  light- 
years  distant  and  are  moving  away  at  the  rate  of  800  miles  a second; 
many  believe  that  the  spiral  nebulae  are  star  galaxies  like  our  Milky 
Way.  Many  astronomers  believe  that  nebulae  have  to  do  with  the 
formation  of  stars,  but  this  much  only  do  they  know  by  observation : they 
have  seen  stars  change  to  nebulae  but  never  the  reverse. 


Sky  Study 


889 


Nebulae  are  practically  beyond  our  unaided  vision;  the  telescope 
reveals  about  eight  thousand  irregular  nebulae  and  photography  shows 
numberless  others.  It  is  thought  that  radiation  from  the  stars  sets  up 
the  activity  in  nebulae  that  gives  off  light.  The  ring  nebulae  are  mere 
dots  compared  with  the  spiral  forms  yet  some  idea  of  their  size  is  given 
by  Ball  who  says  of  the  ring  nebula  of  Lyra,  which  we  cannot  see  with 
the- naked  eye,  if  a railroad  train  started  to  cross  its  middle,  at  the  rate 
of  a mile  a minute,  one  thousand  years  would  not  complete  the  journey. 

The  number  of  stars  that  may  be  seen  with  the  unaided  eye,  if  one  were 
to  travel  from  the  southern  to  the  northern  polar  region,  would  be  between 
six  and  seven  thousand;  but  it  would  require  very  keen  eyes  to  see  two 
thousand  at  one  time.  With  the  help  of  the  telescope,  about  eight  hundred 
thousand  stars  have  been  discovered,  classified  and  catalogued,  while 
photography  of  the  skies  reveals  millions.  It  is  thought  that  the  new 
international  photographic  chart,  which  shall  cover  all  the  space  seen  from 
our  globe  may  show  thirty  millions  of  stars.  The  Milky  Way  or  Galaxy, 
that  great,  white  band  across  the  heavens,  is  made  up  of  stars  which  are  so 
far  away  that  we  cannot  see  them,  but  see  only  their  diffused  light.  It  is 
well  called  a “River  of  Stars”  flowing  in  a circle  around  our  whole  solar 
system ; and,  except  during  the  spring  months,  one-half  of  it  may  be  seen 
directly  above  us  while  the  other  half  is  hidden  below  us.  The  place  of  the 
Milky  Way  in  the  heavens  seems  fixed  and  eternal;  any  star  within  its 
borders  is  always  seen  at  the  same  point.  When  the  Northern  Cross  lifts 
itself  toward  the  zenith  we  are  able  to  see  that,  near  that  constellation,  the 
star  river  divides  into  three  streams  with  long,  blue  islands  between.

HOW  TO  BEGIN  STAR  STUDY 
The  Pole-star  and  the  Dippers 
Teacher's  Story 

The  way  to  begin  star  study  is  to  learn  to  know  the  Big  Dipper,  and 
through  its  pointers  to  distinguish  the  Pole-star;  for  whenever  we  try  to 
find  any  star  we  have  to  find  the  Big  Dipper  and  Pole-star  first  so  as  to  have 
some  fixed  point  to  start  from.  There  are  four  stars  in  the  bowl  of  the  Big 
Dipper  and  three  in  the  curved  handle.  A line  drawn  through  the  outer 
two  stars  of  the  bowl,  if  extended,  will  touch  the  North  Star,  or  Pole-star. 
It  is  very  important  for  us  to  know  the  Pole-star,  because  the  northern  end 
of  the  earth’s  axis  is  directed  toward  it,  and  it  is  therefore  situated  in  the 
heavens  almost  directly  above  our  North  Pole.  For  those  of  us  who  live  in 
the  northern  Hemisphere,  the  North  Star  never  sets,  but  is  always  in  our 
sky.  Of  course,  the  North  Star  has  nothing  to  do  with  the  axis  of  our  earth 


890 


Handbook  of  Nature-Study 


any  more  than  the  figure  on  the  blackboard  has  to  do  with  the  pointer;  it 
simply  happens  to  lie  in  the  direction  toward  which  the  northern  end  of  the 
earth’s  axis  points.  In  the  southern  skies,  there  is  no  convenient  star  which 
lies  directly  above  the  South  Pole,  so  there  is  no  South  Pole-star.  It  is  also 
a coincidence  that  the  needle  of  the  mariner’s  compass  points  toward  the 
North  Star;  the  earth  being  a large  magnet  exercises  its  influence  on  all 
substances  which  can  be  magnetized,  and  since  the  poles  of  our  great  earth- 
magnet  are  nearly  in  line  with  the  poles  of  the  earth’s  axis,  the  magnetic 
needle  naturally  points  approximately  north  and  south  in  many  regions, 
and  the  North  Star  chances  to  be  nearly  in  the  direction  toward  which 
the  northern  end  of  the  compass  needle  points. 

The  Pole-star  cannot  be  seen  from  the  southern  hemisphere;  but  if  we 
should  start  from  Florida,  on  a journey  toward  Baffin’s  Bay,  we  should 
discover  that  each  night  this  star  would  seem  higher  in  the  sky.  And  if 
we  should  succeed  in  reaching  the  North  Pole,  we  would  find  the  Pole- 
star  directly  over  our  heads,  and  what  a wonderful  sight  the  stars  would 
be  from  this  point ! For  none  of  the  stars  which  we  could  see  would  rise 
or  set,  but  would  move  around  us  in  circles  parallel  to  the  horizon. 

The  Big  Dipper  shows  to  us  the  Pole-star,  and  to  us  seems  to  revolve 
around  it  every  twenty-four  hours  but,  of  course,  this  appearance  is  caused 
by  the  fact  that  we  ourselves  are  revolving  from  west  to  east.  Therefore, 
the  stars  seems  to  revolve  from  west  to  east  under  the  Pole-star  and  from 
east  to  west  above  it,  or  in  exactly  the  opposite  direction  in  which  the 
hands  of  a clock  turn.  Owing  to  the  movement  of  the  earth  in  its  orbit,  the 
Big  Dipper  and  all  the  other  stars  arrive  at  a certain  point  in  our  sky  four 
minutes  earlier  each  day  or  about  two  hours  earlier  each  month;  thus,  the 
Big  Dipper  is  east  of  the  Pole-star  with  handle  down  in  the  evenings  of 
January,  while  at  the  same  time  of  night  in  July,  it  is  west  of  the  Pole-star 
with  the  handle  up.  But  the  time  of  year  that  a certain  star  reaches  a cer- 
tain point  is  so  invariable,  that  if  we  know  star  time,  or  sidereal  time  as  it  is 
called,  we  can  tell  just  what  hour  of  the  night  it  is  when  a star  passes  this 
point.  Thus,  the  Big  Dipper  and  the  other  polar  constellations  are  the 
night  clock  of  the  sailors  of  the  northern  hemisphere;  for  though  this  great 
polar  clock  has  its  hands  moving  around  the  wrong  way,  it  gains  time 

with  such  regularity  that  anyone 
who  understands  is  able  to  compute 
exact  time  by  it. 

The  Little  Dipper liesmuchnearer 
the  Pole-star  than  does  the  Big  Dip- 
per; in  fact,  the  Pole-star  itself  is 
the  end  >f  the  handle  of  the  Little 
Dipper.  Besides  the  Pole-star,  there 
are  two  more  stars  in  the  handle 
of  the  Little  Dipper,  and  of  the  four 
stars  which  make  the  bowl,  the  two 
that  form  the  outer  edge  are  much 
the  brighter.  The  bowl  of  the  Little 
Dipper  is  above  or  below  the  Pole- 
star  according  to  the  hour  of  the 
evening,  or  the  night  of  the  year,  for 
it  apparently  revolves  about  the 
The  Pole-star  and  the  Big  and  Little  Dippers.  Pole-star  as  does  the  Big  Dipper. 


Sky  Study  891 

The  two  Dippers  open  toward  each  other,  and  some  one  said  “they  pour 
into  each  other.” 

The  Big  Dipper  is  a part  of  a constellation  called  Ursa  Major,  the 
Great  Bear;  and  the  Little  Dipper  is  the  Little  Bear,  the  handle  of  the 
dipper  being  the  bear’s  tail. 

There  is  an  ancient  myth  telling  the  story  of  the  Big  and  Little 
Bears:  A beautiful  mother  called  Callisto  had  a little  son  whom 

she  named  Areas.  Callisto  was  so  beautiful  that  she  awakened  the 
anger  of  Juno,  who  changed  her  to  a bear;  and  when  her  son  grew  up 
he  became  a hunter,  and  one  day  would  have  killed  his  transformed 
mother;  but  Jupiter  seeing  the  danger  of  this  crime  caught  the  two  up  into 
the  heavens,  and  set  them  there  as  shining  stars.  But  Juno  was  still 
vindictive,  so  she  wrought  a spell  which  never  allowed  these  stars  to  rise  and 
set  like  other  stars,  but  kept  them  always  moving  around  and  around. 

References — The  Friendly  Stars  by  Martin  is  a most  delightful  book  and 
at  the  same  time  gives  explicit  directions  for  finding  the  stars  and  much 
interesting  information  concerning  them.  The  planisphere  is  a little  chart 
with  a mechanical  device  which  enables  us  to  find  what  stars  are  in  sight 
every  night  of  the  year,  or  at  any  time  of  night.  It  is  published  by  Thos. 
Whittaker,  Bible  House,  New  York,  and  costs  seventy-five  cents. 

LESSON  CCXXV 
The  Two  Dippers 

Leading  thought — The  North  Star  or  Pole-star  may  always  be  found  by 
the  stars  known  as  the  pointers  in  the  Big  Dipper;  the  stars  of  the  Big 
Dipper  seem  to  revolve  around  the  Pole-star  once  in  twenty-four  hours. 

Method — The  time  to  begin  these  observations  is  when  the  moon  is  in  its 
last  quarter,  so  that  the  moonlight  will  not  make  pale  the  stars  in  early 
evening.  Draw  upon  the  blackboard,  from  the  chart  shown  on  page  890,  the 
Big  Dipper  and  the  Pole-star,  with  a line  extending  through  the  pointers. 
Say  to  the  pupils  that  this  Big  Dipper  is  above  or  below  or  at  one  side  of  the 
Pole-star,  and  that  you  wish  them  to  observe  for  themselves  where  it  is  and 
tell  you  about  it  the  next  day.  After  they  surely  know  the  Big  Dipper,  ask 
the  following  questions : 

Observations — 1.  Can  you  find  the  Big  Dipper  among  the  stars 

2.  Is  it  in  the  north,  south,  east  or  west? 

3.  Which  stars  are  the  “pointers”  in  the  dipper,  and  why  are  they 
called  so  ? 

4.  Make  a drawing  showing  how  you  can  always  find  the  Pole-star,  if 
you  can  see  the  Big  Dipper. 

5.  How  many  stars  make  the  bowl  of  the  Dipper? 

6 . How  many  stars  in  the  handle  ? 

7 . Is  the  handle  straight  or  is  it  curved  ? 

8.  Does  the  Big  Dipper  open  toward  the  Pole-star,  or  away  from  it? 

9.  Is  it  above  or  below  the  Pole-star  at  eight  o’clock  in  the  evening,  or 
at  the  right  or  the  left  of  it? 

10.  Does  the  Big  Dipper  remain  in  the  same  direction  from  the  Pole- 
star  all  night  ? Look  at  it  at  seven  o’clock  and  again  at  nine  o’clock  and  see 
if  it  has  changed  position  ? 

1 1 . Do  you  think  it  moves  around  the  Pole-star  once  every  twenty-four 
hours  ? In  which  direction  ? How  could  you  tell  the  time  of  night  by  the 
Big  Dipper  and  the  Pole-star? 


892 


Handbook  of  Nature-Study 


1 2 . Does  the  Big  Dipper  ever  rise  and  set  ? 

13.  The  Big  Dipper  is  also  called  the  Great  Bear.  Can  you  find  the 
stars  which  make  the  bear’s  head  and  front  legs? 

After  the  pupils  surely  know  the  Big  Dipper  and  Pole-star  draw  the  com- 
plete diagram  upon  the  board  to  show  the  Little  Dipper  and  where  it  may  be 
found,  and  call  attention  to  the  fact  that  the  end  of  the  Little  Dipper’s 
handle  is  the  Pole-star  itself  and  that  its  bowl  is  not  flaring,  like  that  of  the 
Big  Dipper  and  that  the  two  pour  into  each  other.  Let  the  pupils  find  the 
Little  Dipper  in  the  sky  for  themselves  and  ask  the  following  questions : 

Observations — 14.  Is  the  Little  Dipper  nearer  or  farther  from  the  Pole- 
star  than  the  Big  Dipper  ? 

1 5 . How  many  stars  in  the  handle  of  the  Little  Dipper  ? 

16.  How  many  stars  make  the  bowl  of  the  Little  Dipper?  Which  of 
these  stars  arp  the  brightest?  Is  the  bowl  of  the  Little  Dipper  above  or 
below  the  Pole-star  ? 

17.  Does  the  Little  Dipper  extend  in  the  same  direction  in  relation  to 
the  Pole-star  all  night? 

18.  Make  observations  on  the  relation  to  each  other  of  the  two  dippers 
at  eight  o’clock  in  the  evening  of  January,  February,  March  and  April. 

After  the  above  lessons  are  well  learned,  give  the  following  questions,  and 
try  to  have  the  pupils  answer  by  thinking : 

Questions  about  Polaris  ( the  North  Star ) for  the  pupils  to  think  about  and 
answer: 

19.  How  many  names  has  the  Pole-star?  Can  the  Pole-star  be  seen 
from  the  southern  hemisphere  ? If  not,  why  not  ? 

20.  If  you  should  start  from  southern  Florida  and  travel  straight  north, 
how  would  the  Pole-star  seem  to  change  position  each  succeeding  night  ? 

21.  If  you  could  stand  at  the  North  Pole,  where  would  the  Pole-star 
seem  to  be  ? 

22.  If  you  were  at  the  North  Pole,  would  any  of  the  stars  rise  and  set? 
In  what  direction  would  the  stars  seem  to  move  and  why? 

23.  How  does  the  North  Star  help  the  sailors  to  navigate  the  seas  and 
why? 

24.  How  do  astronomers  reckon  distances  between  us  and  the  stars? 
What  is  a light-year  ? 

Topics  for  English  lesson — (a)  What  a star  is.  (b)  What  a constellation 
is.  ( c ) How  the  stars  and  constellations  received  their  names  in  ancient 
times.  In  ancient  times  the  Big  and  Little  Dippers  were  named  the  Big

CASSIOPEIA’S  CHAIR,  CEPHEUS,  AND  THE  DRAGON 
Teacher's  Story 

There  are  other  constellations  besides  the  two  Dippers,  which  never  rise 
and  set  in  this  latitude,  because  they  are  so  near  to  the  Pole-star  that,  when 
revolving  around  it,  they  do  not  fall  below  the  horizon.  There  is  one  very 
brilliant  star,  called  Capella,  which  almost  belongs  to  the  polar  constella- 


The  polar  constellations  as  they  appear  at  about  8 o'clock  January  20,  the  Dragon 
being  south  of  the  Pole-star.  By  revolving  this  chart  as  indicated,  the  positions 
of  the  stars  is  shown  for  6 p.m.,  midnight,  6 a.  m.  and 
noon  of  January  20th. 

tions  but  not  quite,  for  it  is  far  enough  away  from  Polaris  to  dip  below  the 
horizon  for  four  hours  of  the  twenty-four. 

Queen  Cassiopeia’s  Chair  is  on  the  opposite  side  of  the  Pole-star  from 
the  Big  Dipper  and  at  about  equal  distance  from  it.  It  consists  of  five  bril- 
liant stars  that  form  a W with  the  top  toward  Polaris,  one-half  of  the  W 
being  wider  than  the  other.  There  is  a less  brilliant  sixth  star  which  finishes 
out  half  of  the  W into  a chair  seat,  making  of  the  figure  a very  uneasy  look- 
ing throne  for  a poor  queen  to  sit  upon. 

King  Cepheus  is  Queen  Cassiopeia’s  husband,  and  he  sits  with  one  foot 
on  the  Pole-star  quite  near  to  his  royal  spouse.  His  constellation  is  marked 


894 


Handbook  of  N ature-Study 


by  five  stars,  four  of  which  form  a lozenge,  and  a line  connecting  the  two 
stars  on  the  side  of  the  lozenge  farthest  from  Cassiopeia,  if  extended,  will 
reach  the  Pole-star  as  surely  as  a line  from  the  Big  Dipper  pointers. 
Cepheus  is  not  such  a shining  light  in  the  heavens  as  is  his  wife,  for  his  stars 
are  not  so  brilliant.  Perhaps  this  is  because  he  was  only  incidentally  put  in 
the  skies.  He  was  merely  the  consort  of  Queen  Cassiopeia,  who  being  a 
vain  and  jealous  lady  boasted  that  she  and  her  daughter,  Andromeda,  were 
far  more  beautiful  than  any  other  goddesses  that  ever  were,  and  thus  in- 
curred the  wrath  of  Juno  and  Jupiter  who  set  the  whole  family  “sky  high” 
and  quite  out  of  the  way,  a punishment  which  must  have  had  its  compensa- 
tions since  they  are  where  the  world  of  men  may  look  at  and  admire  them 
for  all  ages. 

Lying  between  the  Big  and  Little  Dippers  and  extending  beyond  the 
latter  is  a straggling  line  of  stars,  which,  if  connected  by  a line,  make  a very 
satisfactory  dragon.  Nine  stars  form  his  body,  three  his  head,  the  two 
brighter  ones  being  the  eyes. 

LESSON  CCXXVI 

Cassiopeia’s  Chair,  Cepheus,  and  the  Dragon 

Leading  thought — To  learn  to  know  and  to  map  the  constellations  which 
are  so  near  the  Pole-star  that  they  never  rise  or  set  in  our  latitude,  but  seem 
to  swing  around  the  North  Star  once  in  twenty-four  hours. 

Method — Place  on  the  blackboard  the  diagram  given  showing  the  Pole- 
star,  Big  and  Little  Dippers  and  Cassiopeia’s  Chair,  and  ask  for  observa- 
tions and  sketches  showing  their  position  in  the  skies  the  following  evening. 
After  the  pupils  have  observed  the  Chair  and  know  it,  add  to  your  diagram, 
first  Cepheus  and  then  the  Dragon.  After  you  are  sure  the  pupils  know 
these  constellations,  give  the  following  lesson.  The  observations  should  be 
made  early  and  late  in  the  same  evening  and  at  different  times  of  the 
month,  so  that  pupils  will  in  every  case  note  the  apparent  movement  of  these 
stars  around  Polaris. 

Observations — i.  How  many  stars  form  Cassiopeia’s  Chair?  Make  a 
drawing  showing  them  and  their  relation  to  the  Pole-star. 

2.  Is  the  Queen’s  Chair  on  the  same  side  of  the  Pole-star  as  the  Big 
Dipper?  Is  the  top  or  the  bottom  of  the  “W”  which  forms  Cassiopeia’s 
Chair  turned  toward  the  Pole-star? 

3.  Does  Cassiopeia’s  Chair  move  around  the  Pole-star,  like  the  Big 
Dipper? 

4.  How  many  stars  mark  the  constellation  of  Cepheus? 

5.  Make  a sketch  of  these  stars  and  show  the  two  which  are  pointers 
toward  the  North  Star. 

6.  Does  Cepheus  also  move  around  the  Pole-star,  and  in  which  diree 
fcion? 

7.  Describe  where  the  Dragon  lies,  and  where  are  his  tail  and  his  head 
in  relation  to  the  two  Dippers.  Make  a sketch  of  the  Dragon. 

8.  Why  do  all  the  poplar  constellations  seem  to  move  around  the  Pole- 
star  every  twenty-four  hours,  and  why  do  they  seem  to  go  in  a direction 
opposite  the  movement  of  the  hands  of  a clock?  What  do  we  mean  by 
“Polar  constellations”?

To  use  the  chart  take  it  in  the  hands,  face  the  Pole-star  and  hold  the  chart  above  the  head 
so  that  the  side  marked  east  will  extend  eastward. 


THE  WINTER  STARS 
Teacher's  Story 

The  natural  time  for  beginning  star  study  is  in  the  autumn 
when  the  days  are  shortening  and  the  early  evenings  give  us 
opportunity  for  observation.  After  the  polar  constellations  are  learned, 
we  are  then  ready  for  further  study  in  the  still  earlier  evenings  of  winter, 
when  the  clear  atmosphere  and  beautiful  blue  of  the  heavens  make  the  stars 
seem  more  alive,  more  sparkling,  and  more  beautiful  than  at  any  other 
period  of  the  year.  One  of  the  first  lessons  should  be  to  instruct  the  pupils 
how  to  draw  an  imaginary  straight  line  from  one  star  to  another,  and  to 
perceive  the  angles  which  such  lines  make  when  they  meet  at  a given  star. 
A rule,  or  what  is  just  as  effective,  a postal  card  or  some  other  piece  of  stiff 
paper  which  shows  right-angled  corners,  is  very  useful  in  this  work.  It 
should  be  held  between  the  eyes  and  the  stars  which  we  wish  to  connect,  and 
thus  make  us  certain  of  a straight  line  and  a right  angle. 

Orion  ( o-ri'on ) 

During  the  evenings  of  January,  February  and  March  the  splendid  con- 
stellation of  Orion  takes  possession  of  the  southern  half  of  the  heavens;  and 
so  striking  is  it  that  we  find  other  stars  by  referring  to  it  instead  of  to  the 
Pole-star.  Orion  is  a constellation  which  almost  everyone  knows;  three 
stars  in  a row  outline  his  belt,  and  a curving  line  of  stars,  set  obliquely 
below  the  belt,  outline  the  sword.  Above  the  belt  in  the  evening  sky  we  can 


896 


Handbook  of  Nature-Study 


■ see  the  splendid  red  star  Betelgeuse  (bet-el-gerz) , and 
below  the  belt,  at  about  an  equal  distance,  is  the  white 
star  Rigel  ( re-jel ).  West  of  the  red  star  above,  and  east 
of  the  white  star  below,  are  two  fainter  stars,  and  if 
these  four  stars  are  connected  by  lines,  an  irregular  four- 
sided figure  results,  which  includes  the  belt  and  the 
sword.  In  this  constellation  the  ancients  saw  Orion,  the 
great  hunter,  with  his  belt  and  his  sword ; Betelgeuse  was 
set  like  a glowing  ruby  on  his  shoulder,  and  the  white 
star  Rigel  was  set  like  a spur  on  his  heel.  Thus,  stood 
the  great  hunter  in  the  sky,  with  his  club  raised  to  keep 
off  the  plunging  bull  whose  eye  is  the  red  Aldebaran 
Orion,  the  three  large  (al-deb' a-ran) . And  beyond  him  follows  the  Great  Dog 
stars  in  a line  form-  with  the  bright  blue  star  Sirius  ( sir'i-us ) in  his  mouth, 
ing  the  belt,  the  an(}  the  Little  Dog  branded  by  the  white  star  Procyon

geuse  above , Rigel  stellation  the  Yard-ell  or  the  Ell-yard. 
below.  The  three  beautiful  stars  which  make  Orion’s  belt 

are  all  double  stars;  the  belt  is  just  three  degrees 
long  and  is  a good  unit  for  sky  measurement.  The  sword  is  not 
merely  the  three  stars  which  we  ordinarily  see,  but  is  really  a curved 
line  of  five  stars;  and  what  seems  to  be  the  third  star  from  the  tip 
of  the  sword  and  which  looks  hazy,  is  in  fact  a great  nebula.  Through  the 
telescope  this  nebula  seems  a splash  of  light  with  six  beautiful  stars  within 
it.  The  first  star  in  Orion  to  appear  above  the  horizon  is  red  Betelgeuse, 
a blushing  young  giant  just  starting  on  its  career  as  a star;  it  is  com- 
posed of  a gas  much  thinner  than  our  air.  Its  diameter  is  215,000,000 
miles,  which  is  millions  more  than  that  of  the  Earth’s  orbit.  It  is  one 
hundred  and  sixty  light-years  away  from  us  and  it  is  receding  from  us 
all  the  time.  About  fifteen  minutes  after  Betelgeuse  rises,  and  after  the 
belt  and  sword  are  in  sight,  a white  sparkling  star  appears  at  the  south- 
west of  the  belt.  This  is  Rigel,  and  its  distance  is  too  great  to  measure. 

LESSON  CCXXVII 
Orion 

Leading  thought — Orion  is  one  of  the  most  beautiful  constellations  in  the 
heavens.  It  is  especially  marked  by  the  three  stars  which  form  Orion’s 
belt,  and  the  line  of  stars  below  the  belt  which  form  the  sword. 

Method — Place  on  the  blackboard  the  outline  of  Orion  as  given  in  the 
diagram.  Ask  the  pupils  to  make  the  following  observations  in  the  even- 
ing and  give  their  report  the  next  day. 

Observations — 1.  Where  is  Orion  in  relation  to  the  Pole-star? 

2.  How  many  stars  in  the  belt  of  Orion?  How  many  stars  in  the 
Sword?  Can  you  see  plainly  the  third  star  from  the  bottom  of  the  sword? 

3.  Notice  above  the  belt,  about  three  times  its  length,  a bright  star; 
this  is  Betelgeuse.  What  is  the  color  of  this  star?  What  do  we  know 
about  the  age  of  a star  if  it  is  red  ? 

4.  Look  below  the  belt  and  observe  another  bright  star  at  about  the 
same  distance  below  that  Betelgeuse  is  above.  What  is  the  color  of  thie 
star?  What  does  its  color  signify?  The  name  of  this  star  is  Rigel.

5.  Note  that  west  of  the  red  star  above  and  east  of  the  white  star 
below  are  two  fainter  stars.  If  we  connect  these  four  stars  by  lines  we 
shall  make  an  irregular  four-sided  figure,  fencing  in  the  belt  and  sword. 
Sketch  this  figure  with  the  belt  and  sword,  and  write  on  your  diagram 
the  name  of  the  red  star  above  and  the  white  star  below  and  also  the 
name  of  the  constellation. 

6.  Which  star  of  the  constellation  rises  first  in  the  evening?  Which 
last? 

7.  Write  an  English  theme  on  the  story  of  Orion,  the  great  hunter.

ALDEBARAN  AND  THE  PLEIADES 

Teacher's  Story 

Almost  in  a line  with  the. belt  of  Orion,  up  in  the  skies  northwest  from 
it,  is  the  rosy  star  Aldebaran.  This  star,  which  is  also  a ruddy  young 
giant,  marks  the  end  of  the  lower  arm  of  a V-shaped 
constellation  composed  of  this  and  four  other  stars. 

This  constellation  is  the  Hyades  ( hi'a-dez ).  The 

Hyades  is  a part  of  the  constellation  called  by  the 
ancients  Taurus,  the  bull,  and  is  the  head  of  the  in- 
furiated animal.  Aldebaran  is  a comparatively  near 
neighbor  of  ours,  since  it  takes  light  only  thirty-two-^^&araw  in  the  V- 
years  to  pass  from  it  to  us.  It  gives  off  about  forty-  shaped  constellation 
five  times  as  much  light  as  does  our  sun ; it  lies  in  the  C^h-S  is  ea  p“rt 
path  traversed  by  the  moon  as  it  crosses  the  sky,  and  the  constellation, 
is  often  thus  hidden  from  our  view.  Taurus. 

Although  we  are  attracted  by  many  bright  stars  in  the  winter  sky, 
yet  there  is  a little  misty  group  of  stars,  which  has  ever  held  the  human 
attention  enthralled,  and  of  which  the  poets  of  all  the  ages  have  sung. 
These  stars  are  called  the  Pleiades  ( ple'ya-dees) ; most  eyes  can  count 
only  six  stars  in  the  constellation.  There  are  nine  stars  large  enough 
to  be  seen  through  the  telescope,  and  which  have  been  given  names; 
but  sky  photography  has  revealed  to  us  that  there  are  more  than  three 
thousand  stars  in  this  little  group.  Perhaps  no  stars  in  the  heavens 
give  us  such  a feeling  of  the  infinity  of  the  universe  as  do  the  Pleiades; 
for  astronomers  believe  that  they  form  a great  star  system,  known  as 
one  of  the  globular  nebulae.  The  reason  for  this  belief  is  that  these  stars 
seem  to  be  surrounded  by  a brilliant  mist  which 
sometimes  seems  to  be  looped  from  one  to  another; 
and,  too,  the  stars  are  all  in  the  same  stage 
of  development  and  have  the  same  chemical  com- 
position, and  they  are  all  moving  together  in  the 
same  direction.  These  stars  which  look  so  close 
together  to  us  are  so  far  apart  really  that  our  own

in  the  Pleiades  to  another.  The  Pleiades  are  so  far 
from  us  that  only  recently  have  astronomers  estimated  that  it  takes 
light  six  hundred  years  to  reach  us  from  them.  There  is  a mythical 


8g8 


Handbook  of  Nature-Study 


story  found  in  literature,  that  once  the  unaided  eye  could  see  seven 
instead  of  six  stars  in  the  Pleiades,  and  much  poetic  imagining  has  been 
developed  to  account  for  the  “lost  Pleiad.” 

LESSON  CCXXVIII 
Aldebaran  and  the  Pleiades 

Leading  thought — The  Pleiades  seem  to  be  a little  misty  group  of  six 
stars,  but  instead  there  are  in  it  three  thousand  stars.  Half  way  between 
the  Pleiades  and  Orion’s  belt  is  Aldebaran,  an  ageing  ruddy  star. 

Method — Draw  the  diagram  (p.  895)  on  the  blackboard  showing  Orion, 
Aldebaran  and  the  Pleiades,  and  the  lines  B,  C,  D.  Give  an  outline  of 
the  observations  to  be  made  by  the  pupils,  and  let  them  work  out  the 
answers  when  they  have  opportunity.  Each  pupil  should  prepare  a chart 
of  these  constellations. 

Observations — 1.  Imagine  a line  drawn  from  Rigel  to  Betelgeuse  and 
then  another  line  just  as  long  extending  to  the  west  of  the  latter  at  a little 
less  than  a right  angle,  and  it  will  end  in  a bright,  rosy  star,  not  so  red  as 
Betelgeuse. 

2.  What  is  the  name  of  this  star  ? Write  it  on  your  chart. 

3 . Can  you  see  the  figure  V formed  by  Aldebaran  and  four  fainter  stars  ? 
Sketch  the  V and  show  where  in  it  Aldebaran  belongs.  This  V-shaped 
constellation  is  called  the  Hyades. 

4.  Imagine  a line  drawn  from  Orion’s  belt  to  Aldebaran  and  extend  it 
to  not  quite  an  equal  length  beyond  it,  and  it  will  end  near  a “fuzzy  little 
bunch”  of  stars  which  are  called  the  Pleiades.  Place  the  Pleiades  on  your 
chart. 

5 . How  many  stars  can  you  see  in  the  Pleiades  ? 

6.  Why  are  they  called  the  seven  sisters? 

7.  How  many  stars  in  the  Pleiades  which  are  named,  and  how  many 
does  photography  show  that  there  really  are  in  the  group? 

8.  How  far  apart  from  each  other  are  the  nearest  neighbors  of  the 
Pleiades  ? 

9.  What  do  the  astronomers  think  about  the  Pleiades  and  why  do  they 
think  this  ? 


THE  TWO  DOG  STARS,  SIRIUS  AND  PROCYON 
Teacher's  Story 

If  a line  from  Aldebaran  pass  through  the  belt  of  Orion  and  is  extended 
about  as  far  on  the  other  side,  it  will  reach  the  Great  Dog  Star,  following  at 
Orion’s  heels.  This  is  Sirius,  (Sir'-e-us)  the  most  brilliant  of  all  the  stars  in 
our  skies,  glinting  with  ever  changing  colors,  sometimes  blue,  at  others  rosy 
or  white.  It  must  have  been  of  this  star  that  Browning  wrote : 

“All  that  I know 
Of,  a certain  star 
Is,  it  can  throw 
(Like  the  angled  spar) 

Now  a dart  of  red, 

Now  a dart  of  blue.” 


Sky  Study 


899 


Sirius  has  reached  the  blue- 
white  stage  of  star  develop- 
ment. Although  it  is  larger 
than  our  sun,  its  superior 
brilliance  is  due  to  its  near- 
ness to  us;  it  is  only  eight 
and  one-half  light-years  away 
from  us  and  is  the  most  cele- 
brated star  in  literature.  The 
ancients  knew  it,  the  Egyp- 
tians worshipped  it,  Homer 
sang  of  it,  and  it  has  had  its 
place  in  the  poetry  of  all  ages. 

Procyon,  ( pro'-se-on ) the 
Little  Dog  Star,  was  so-called 
perhaps  because  it  trots  up  the 
eastern  skies  a little  ahead  of 
the  magnificent  Great  Dog 
Star;  it  gives  out  eight  times 
as  much  light  as  our  sun,  and  is  only  ten  light-years  away  from  us.  It  has  a 
fainter  companion  about  three  or  four  degrees  to  the  northwest  of  it.

B,  Betelgeuse;  R,  Rigel;  S,  Sirius,  the  Great  Dog  Star; 
P,  Procyon,  the  Little  Dog  Star. 


LESSON  CCXXIX 

The  Two  Dog  Stars 


Leading  thought — The  Great  Dog  Star,  Sirius,  is  the  most  famous  of  all 
stars  in  the  literature  of  the  ages.  The  Two  Dog  Stars  were  supposed  by 
the  ancients  to  be  following  the  great  hunter,  Orion. 

Method — Draw  upon  the  board  from  the  chart  shown  on  this  page,  the 
constellation  of  Orion  with  Sirius  and  Procyon.  Ask  the  pupils  to  note 
that  after  Orion  is  well  up  in  the  sky  a straight  line  drawn  through  Orion’s 
belt  and  dropping  down  toward  the  eastern  horizon  ends  in  a beautiful 
white  star,  which  is  Sirius.  And  that  if  we  draw  a line  from  Betelgeuse  to 
Rigel  from  Rigel  to  Sirius  and  then  draw  lines  to  complete  a quadrangle,  we 
shall  find  our  lines  meet  at  a bright  star  just  a little  too  far  away  to  make 
the  figure  a square,  but  making  it  somewhat  kite-shaped  instead.  This  is 
the  Little  Dog  Star,  Procyon,  and  it  has  a twin  star  near  it.  After  giving 
these  directions  let  the  children  make  the  following  observations : 

1 . How  do  you  find  Sirius  ? Which  rises  first,  Orion  or  Sirius  ? 

2 . What  color  is  Sirius  ? Judging  from  its  color  what  stage  of  develop- 
ment do  you  think  it  is  in  ? 

3 . Try  and  find  out  how  large  Sirius  is  compared  with  our  sun  and  how 
near  it  is  to  us. 

4.  Why  is  Sirius  called  the  Great  Dog  Star?  Is  the  Little  Dog  Star 
nearer  to  the  North  Star  than  Sirius?  Which  is  the  brighter,  the  Great 
Dog  Star  or  the  Little  Dog  Star?  Can  you  see  any  fainter  star  near 
Procyon? 

5.  Why  is  Procyon  called  the  Little  Dog  Star? 

6.  Make  a chart  showing  Orion  and  the  two  Dog  Stars.

CAPELLA  AND  THE  HEAVENLY  TWINS 
Teacher's  Story 

Capella  is  nearer  to  the  North  Star  than  any  other 
of  the  bright  stars  and  it  comes  very  near  belonging 
to  the  strictly  polar  constellations,  since  it  falls  below 
the  horizon  only  four  hours  out  of  twenty-four.  In 
composition  it  much  resembles  our  sun,  as  do  all  the 
bright  yellow  stars ; but  it  is  much  larger ; it  gives  off 
one  hundred  and  twenty  times  as  much  light  as  our 
sun,  and  it  is  forty  light-years  away  from  us.  Capella 
is  always  a beautiful  feature  of  the  northern  skies, 
being  almost  in  the  zenith  during  the  evenings  of 
January  and  February.  It  is  in  a brilliant  shield, 
shaped  constellation  known  as  Auriga.  Capella  is  a double  star. 

During  the  winter  evenings  we  see  two  stars  set  like  glowing  eyes  almost 
in  the  zenith,  and  in  a region  of  the  sky  where  there  are  no  other  bright  stars. 
These  twin  stars  are  set  just  a little  closer  together  than  are  the  pointers  of 
the  Big  Dipper.  To  this  brilliant  pair  the  ancients  gave  the  names  of 
Castor  and  Pollux.  Pollux  is  the  brighter  of  the  two  and  is  the  more  south- 
ward in  situation.  Pollux  and  Castor  were  two  beauti- 
ful twin  boys  who  loved  each  other  so  much  that,  after 
they  were;  dead,  they  were  placed  in  the  skies  where 
they  could  always  be  near  each  other.  The  twin  stars 
are  supposed  to  exert  a benign  influence  on  oceans  and 
seas  and  are,  therefore,  beloved  by  sailors.  Although 
they  seem  to  us  so  near  together,  they  are  separated  by 
a space  so  great  that  we  cannot  conceive  of  it  and  they 
are  going  in  opposite  directions. 

Pollux  is  a ye1  low  star,  and  supposed  to  be  in  the  same 
stage  of  development  as  our  sun,  while  Castor  is  white 
and  according  to  star  ages  is  young.  When  a boy  says  “By  Jimminy,” 
he  does  not  realize  that  he  is  using  an  ancient  expletive  “By  Gemini,” 
which  is  the  Latin  name  of  these  twin  stars  and  was  a favorite  ancient  oath, 
especially  of  sailors. 

LESSON  CCXXX 
Capella  and  the  Heavenly  Twins 

Leading  thought — There  are,  during  the  evenings  of  January  and  Febru- 
ary, three  brilliant  stars  almost  directly  overhead.  One  of  these  is  Capella, 
the  other  two  are  the  Heavenly  Twins. 

Method — Place  on  the  board  the  part  of  the  chart  (p.  895)  showing  the 
Big  Dipper,  Pole-star,  Capella  and  the  Twins.  Draw  a line,  L,  from  the 
pointers  of  the  Big  Dipper,  and  extend  it  to  the  Pole-star.  Draw  another 
line,  K,  from  the  Pole-star  at  right  angles  to  the  line  L,  and  on  the  side 
away  from  the  Big  Dipper’s  handle,  and  it  will  pass  through  a large,  bril- 
liant, yellow  star  which  is  Capella.  Ask  the  pupils  to  imagine  similar 
lines  drawn  across  the  sky,  when  they  are  making  their  observations  and 
thus  find  these  stars,  and  to  place  them  on  their  charts,  making  the 
following  observations : 

1.  What  color  is  Capella,  and  how  does  its  color  compare  with  that  of 
our  sun? 


Gemini,  the  heavenly 
twins,  the  larger 
one  is  Pollux  and 
the  other  is  Castor.

lation Auriga.

2.  Is  Capella  as  near  to  the  Pole-star  as  the  Big  Dipper?  Is  it  near 
enough  so  that  it  never  sets  ? 

3 . Can  you  see  the  shield-like  constellation  of  which  Capella  is  a part  ? 
Do  you  know  the  name  of  this  constellation  ? 

4.  How  do  you  find  the  Heavenly  Twins  after  you  have  found  Capella? 

5.  Why  are  these  stars  called  the  Heavenly  Twins?  What  is  their 
Latin  name  ? What  are  the  names  of  the  two  stars  ? Are  these  twins  set 
nearer  together  than  the  pointers  of  the  Big  Dipper  ? 

6.  How  can  you  tell  the  Heavenly  Twins  from  the  Little  Dog  Star  and 
its  companion  ? 

7.  Read  in  the  books  all  that  you  can  find  about  the  Heavenly  Twins. 
Try  and  find  if  they  are  the  same  age,  if  they  are  as  near  together  as  they 
seem,  and  if  they  are  going  in  the  same  direction.  What  did  the  ancient 
sailors  think  of  these  twin  stars  ? 


THE  STARS  OF  SUMMER 

To  us,  who  dwell  in  a world  of  change,  the  stars  give  the  comfort  of 
abidingness ; they  remain  ever  the  same  to  our  eyes  and  the  teacher  should 
make  much  of  this.  When  we  once  come  to  know  a star,  we  know  exactly 
where  to  find  it  in  the  heavens,  wherever  we  may  be.  A star  which  a person 
knows  during  childhood  will,  in  later  life  and  in  other  lands,  seem  a staunch 
friend  and  a bond,  drawing  him  back  to  his  early  home  and  associations.

Handbook  of  Nature-Study 


The  summer  is  an  enticing  season  for  making  the  acquaintance  of  eight 
of  the  fifteen  brightest  stars  visible  in  northern  latitudes.  F ew  midsummer 
entertainments  rival  that  of  lying  on  one’s  back  on  the  grass  of  some  open 
space  which  commands  a wide  view  of  the  heavens,  and  there  with  a plani- 
sphere and  an  intermittently  lighted  candle  with  which  to  consult  it,  learn 
by  sight,  by  name  and  by  heart  those  brilliant  stars  which  will  ever  after 
meet  with  friendly  greeting  our  uplifted  eyes.  To  teach  the  children  in  a 
true  informing  way  about  the  stars,  the  teacher  should  know  them,  and 
nowhere  in  nature’s  realm  is  there  a more  thought-awakening  lesson. 


LESSON  CCXXXI 
The  Bright  Stars  of  Summer 

Leading  thought — The  stars  which  we  see  shining  during  summer  even- 
ings are  not  the  same  ones  that  we  see  during  the  winter  evenings,  except 
those  in  the  polar  constellations.  There  are  eight  of  the  brilliant  summer 
stars,  which  we  should  be  able  to  distinguish  and  call  by  name. 

Method — Begin  by  the  middle  of  May  when  the  Big  Dipper  is  well  above 
the  Pole-star  in  the  early  evening,  and  when,  therefore,  Regulus,  Spica, 
Arcturus  and  the  Crown  are  high  in  the  sky.  The  others  may  be  learned  in 
June,  although  July  is  the  best  month  for  observing  them.  In  teaching  the 
pupils  how  to  find  the  stars,  again  instruct  them  how  to  draw  an  imaginary 
straight  line  from  one  star  to  another  and  to  observe  the  angles  made  by 
such  lines  connecting  three  or  four  stars. 

Place  upon  the  blackboard  the  figures  from  the  chart  (page  901),  as 
indicated,  leaving  each  one  there  until  the  pupils  have  observed  and  learned 
it.  Then  erase  and  place  another  figure.  In  each  case  try  to  get  the  pupils 
interested  in  what  we  know  about  each  star,  a brief  summary  of  which  is 
given.  Note  that  the  observations  given  in  the  lessons  are  for  early  in  the 
evenings  of  the  last  of  May,  of  June,  and  of  early  July. 

Regulus  ( reg'-u-lus ) 

Draw  upon  the  blackboard  from  the  chart  (p.  901) 
the  Pole-star,  the  Big  Dipper,  the  line  G and  the  Sickle 
shown  just  below  the  outer  end  of  the  line.  Extend 
the  line  that  passes  through  the  pointers  of  the  Big 
Dipper  to  the  North  Star  backward  into  the  western 
skies ; just  west  of  this  line  lies  a constellation  called  the 
Sickle,  and  the  stars  that  form  it  outline  this  implement. 
The  Sickle  has  a jewel  at  the  end  of  the  handle,  which  is 
a white  and  diamond-glittering  star  called  Regulus. 
It  is  a great  sun  giving  out  one  thousand  times  as  much 
light  as  our  own  sun,  and  this  light  reaches  us  in  about 
one  hundred  and  sixty  years.  The  Sickle  is  part  of  a 
constellation  called  the  Lion,  and  from  which  comes  the  shower  of 
meteors  which  we  see  on  the  evening  of  November  13th.  Regulus  is 
seen  best  in  Spring. 

Arcturus  ( ark-tu'rus ) 

Place  on  the  blackboard  the  Big  Dipper,  the  Pole-star  and  the  line 
E,  Arcturus  and  the  Crown.  Extend  the  handle  of  the  Big  Dipper  fol- 


Regulus , the  large 
star  in  the  handle

lowing  its  own  curve  for  about 
twice  its  length  and  it  will  end 
in  a beautiful,  yellow  star,  the 
only  very  bright  one  in  that 
region.  It  is  a thousand 
times  brighter  than  our  own 
sun,  but  its  light  does  not 
reach  us  for  a hundred  years 
after  it  is  given  off.  Arcturus 
is  supposed  to  be  one  of  the  largest  of  all  the  suns,  having  a diameter  of 
twenty-one  million  miles.  During  the  latter  part  of  June  and  July  it  is 
almost  overhead  in  the  early  evening. 

The  Crown 

Between  Arcturus  and  Vega,  but  much  nearer  the  former, 
is  a circle  of  smaller  stars  that  is  called  the  Northern  Crown, 
and  which  because  of  its  form  is  quite  noticeable. 

Spica  ( spi'-ka ) 

Place  on  the  blackboard  the  Big  Dipper,  the  Pole-star,  the 
line  F and  Spica.  To  find  Spica  draw  a line  through  the  star 
on  the  outer  edge  of  the  top  of  the  bowl  of  the  Big  Dipper, 
The  North-  through  the  star  at  the  bottom  of  the  bowl  next  the  handle, 
ern  Crown,  and  extend  this  line  far  over  to  the  southwest,  during  the  even- 
ings of  June  and  July.  (See  page  901)  In  August,  this  star 
sets  at  ten  o’clock.  Spica  is  a white  star,  and  is  the  only  bright  one  in  that 
part  of  the  sky.  It  is  so  far  away  from  us  that  the  distance  has  never  been 
measured.  Spica  is  in  the  constellation  called  the  Virgin. 

Vega  (vee'-ga) 

Place  on  the  blackboard  the  Pole-star,  the  Big  Dipper, 
the  lines  H and  I and  Vega  with  her  five  attendant  stars, 
as  shown  in  the  chart.  Teach  that  these  stars  are  the 
chief  ones  in  the  constellation  called  The  Lyre.  To  find 
Vega,  draw  a line  from  the  Pole-star  to  the  star  in  the  Big 
Dipper  which  joins  the  bowl  to  the  handle.  Then  draw  a 
line  at  right  angles  to  this  (see  chart  lines  H,  I)  and  extend 
the  line  I a little  farther  from  the  North-star  than  is  the 
end  star  of  the  Dipper  handle ; this  line  will  reach  a bright 
star,  bluish  in  color,  which  can  always  be  identified  by  four 
smaller  attendant  stars  which  lie  near  it  and  outline  a 
parallelogram  with  slanting  ends.  Vega  is  the  most 
brilliant  summer  star  that  we  see  in  the  northern  hemi-  Vega andher train 
sphere.  It  is  a very  large  sun,  giving  out  ninety  times  as  of  five  stars. 
much  light  as  our  sun;  it  is  so  far  away  that  it  requires 
twenty-nine  years  for  a ray  of  light  to  reach  us  from  it.  Vega’s  chief 
interest  for  us,  aside  from  its  beauty,  is  that  toward  it  our  sun  and  all  its 
planets,  including  our  earth,  are  moving  at  the  rate  of  thirteen  miles  per 
second.

Antares,  a brilliant 
star  in  the  south- 
ern skies. 


Antares  ( an-ta'-rees ) 

Add  to  the  last  diagram  on  the  blackboard  the  line  E, 
Arcturus,  the  line  B and  Antares.  To  find  this  star, 
draw  a line  half  way  between  Arcturus  and  Vega  from 
the  Pole-star  straight  across  the  sky  to  the  south,  and 
just  above  the  southern  horizon  it  will  point  to  the  glow- 
ing star,  Antares,  in  the  constellation  of  the  Scorpion. 
Also  a line  drawn  at  right  angles  to  the  line  connecting 
Altair  with  its  companions  and  extending  toward  the 
south  will  reach  Antares.  Late  June  and  July  about 
ten  o’clock  in  the  evening  is  the  best  for  viewing  this 
beautiful  star.  An  interesting  thing  about  Antares  is  that  it  is  the  greatest 
of  the  young  giant -stars  yet  measured;  it  has  a diameter  of  400,000,000 
miles. 

Deneb,  or  Arided  ( den'-eb ; a'-ri-ded) 

Erase  from  the  last  diagram  Antares  and  the 
line  B . Add  to  it  the  lines  C and  D making  a right 
angle  at  Deneb ; and  the  Cross — the  head  of  which 
is  Deneb,  the  foot  ending  near  the  letter  on  line  L. 

This  star  is  at  the  head  of  the  Northern  Cross, 
which  is  a very  shaky  looking  cross  and  appears 
upside  down  in  the  eastern  skies  during  the  evenings 
of  June  and  July.  Deneb  is  white  in  color  and 
is  a very  large  sun,  because  it  seems  to  us  a bright 
star  although  it  is  so  far  away  from  us  that  the 
distance  has  never  been  surely  measured;  but  it 
has  been  estimated  that  a ray  of  light  would  need 
at  least  three  hundred  and  twenty-five  years  to 
reach  us  from  Deneb.  It  and  the  cross  are  a part 
4f  the  constellation  of  Cygnus,  or  the  Swan.

Altair

stellation of  the 
Eagle. 


Add  to  the  last  diagram  on  the  board  the  lines  L,  K, 
Altair  and  its  two  attendant  stars  and  the  Dolphin.  Em- 
phasize the  fact  that  Altair  marks  the  constellation  of 
Aquila,  or  the  Eagle.  This  beautiful  star  is  easily  distin- 
guished because  of  its  small  companions,  one  on  each  side, 
all  three  in  a line.  The  three  belong  to  a constellation 
called  the  Eagle,  and  may  be  seen  in  early  evening  from  June 
to  December.  Altair,  Deneb  and  Vega  form  a triangle  with 
the  most  acute  angle  at  Altair.  (See  chart  L,  K.)  Just 
northeast  of  Altair  is  a little  diamond-shaped 
cluster  of  stars  called  the  Dolphin,  which 
is  a good  name  for  it,  since  it  looks  like  a 
Dolphin,  the  fifth  star  forming  the  tail.  It  is 
also  called  Job’s  Coffin,  but  the  reason  for  this  is 
uncertain,  unless  Job’s  trials  extended  to  a 
coffin  which  could  not  possibly  fit  him.  If  the 
line  C on  the  chart  drawn  from  the  Pole-star  to  The  Dolphin  or  Job's  Coffin.. 
Deneb  be  extended,  it  will  touch  the  Dolphin.  Altair  is  always  low  in 
the  sky;  it  is  a great  sun  giving  off  nearly  ten  times  as  much  light  as  our 
own  sun ; light  reaches  us  from  it  in  fifteen  years.

THE  SUN 
Teacher's  Story 

To  be  retold  to  pupils. 

If,  only  once  in  a century,  there  came  to  us  from  our  great  sun,  light  and 
heat,  bringing  the  power  to  awaken  dormant  life,  to  lift  the  plant  from  the 
seed  and  clothe  the  earth  with  verdure,  then  it  would  indeed  be  a miracle. 
But  the  sun  by  shining  every  day  cheapens  its  miracles  in  the  eyes  of  the 
thoughtless.  While  it  hardly  comes  within  the  province  of  the  nature- 
study  teacher  to  make  a careful  study  of  the  sun,  yet  she  may  surely  stimu- 
late in  her  pupils  a desire  to  know  something  of  this  great  luminous  center 
of  our  system. 

Our  sun  is  a great  shining  globe  about  one  hundred  and  ten  times  as 
thick  through  as  the  earth,  and  more  than  a million  times  as  large.  If  we 
look  at  the  sun  in  a clear  sky,  it  is  so  brilliant  that  it  hurts  our  eyes.  Thus, 
it  is  better  to  look  at  it  through  a smoked  glass,  or  when  the  atmosphere  is 
very  hazy.  If  we  should  see  the  sun  through  a telescope,  we  should  find 
that  its  surface  is  not  one  great  glare  of  light  but  is  mottled,  looking  like  a 
plate  of  rice  soup,  and  at  times  there  are  dark  spots  to  be  seen  upon  its  sur- 
face. Some  of  these  spots  are  so  large  that  during  very  “smoky  weather” 
we  can  see  them  with  the  naked  eye.  In  September,  1908,  a sun-spot  was 
plainly  visible ; it  was  ten  thousand  miles  across,  and  our  whole  world  could 
have  been  dropped  into  it  with  a thousand  miles  to  spare  all  around  it.  We 
do  not,  know  the  cause  of  these  sun-spots,  but  we  know  they  appear  in 
greater  numbers  in  certain  regions  of  the  sun,  above  and  below  the  equator. 
And  since  each  sun-spot  retains  its  place  on  the  surface  of  the  sun,  just  as  a 
hole  dug  in  the  surface  of  our  earth  would  retain  its  place,  we  have  been  able 
to  tell  by  the  apparent  movement  of  these  spots  how  rapidly  and  in  which 
direction  the  sun  is  turning  on  its  axis;  it  revolves  once  in  about  twenty-six 
days  and,  since  the  sun  is  so  much  larger  than  our  earth,  a spot  on  the 
equator  travels  at  a rate  of  more  than  a mile  a second.  There  is  a queer 
thing  about  the  outside  surface  of  the  sun — the  equator  rotates  more 
rapidly  than  the  parts  lying  nearer  the  poles ; this  shows  that  the  sun  is  a 
gaseous  or  liquid  body,  for  if  it  were  solid,  like  our  earth,  all  its  parts  would 
have  to  rotate  at  the  same  rate.  At  periods  of  eleven  years  the  greatest 
number  of  spots  appear  upon  the  sun. 

Another  interesting  feature  of  the  sun  is  the  tremendous  explosion  of 
hydrogen  gas  mixed  with  the  vapors  of  calcium  and  magnesium,  which 
shoot  out  flames  from  twenty-five  thousand  to  three  hundred  thousand 
miles  high,  at  a rate  of  speed  two  hundred  times  as  swift  as  a rifle  bullet 
travels.)  Think  what  fireworks  one  might  see  from  the  sun’s  surface  all  the 
time!  One  would  not  need  to  wait  until  the  Fourth  of  July  for  fireworks 
there.  These  great,  explosive  flames  can  be  seen  by  the  telescope  when  the 
moon  eclipses  the  sun,  and  they  have  been  analyzed  by  means  of  the 
spectroscope.  Besides  these  magnificent  explosions,  there  is  surrounding 
the  sun  a glow  which  is  brighter  near  the  sun ’si  surface  and  paler  at  the 
edges;  it  is  a magnificent  solar  halo,  some  of  its  streamers  being  millions  of 
miles  long.  This  halo  is  called  the  Corona,  and  is  visible  during  total 
eclipses.  By  means  of  the  spectroscope  we  know  that  there  are  about 
fifty  chemical  elements  in  the  sun,  which  are  the  same  as  those  we  find 
upon  our  earth. 

The  sun  weighs  330,000  times  as  much  as  the  earth;  the  force  of  grav- 
ity upon  its  surface  is  twenty-seven  and  two-thirds  times  as  much  as  it

is  here.  A letter  which  weighs  an  ounce  here  would  weigh  almost  a pound 
and  three  quarters  on  the  sun;  and  a man  of  ordinary  size  in  this  world 
would  weigh  more  than  two  tons  there,  and  would  be  crushed  to  death  by 
his  own  weight.  Find  how  much  your  watch,  your  book,  your  pencil,  your 
baseball,  your  football  would  weigh  on  the  sun. 

Our  Sun  and  its  Family 

First  of  all  we  shall  have  to  acknowledge  that  our  great,  blazing  sun  is 
simply  a medium-sized  star,  not  nearly  so  large  as  Vega,  nor  even  as  large 
as  the  Pole-star;  but  it  happens  to  be  our  own  particular  star  and  so  is  of 
the  greatest  importance  to  us.  The  sun  has  several  other  worlds,  more  or 
less  like  our  own,  revolving  around  it  on  almost  the  same  level  or  plane  in 
which  our  world  revolves,  but  some  of  these  worlds  are  much  nearer  the  sun 
and  others  much  farther  away  than  ours.  Nearest  of  all  is  Mercury,  but  it 
is  not  half  so  thick  through  as  our  earth,  and  it  is  so  close  to  the  sun  that  it 
circles  around  in  88  days ; that  is,  its  year  is  only  88  days  long.  Next  comes 
Venus,  almost  as  large  as  the  earth,  with  a year  225  days  long;  next  comes 
our  earth,  which  completes  its  year  in  365  days;  next  beyond  us  is  Mars,  a 
little  more  than  half  as  thick  as  the  earth  and  with  a year  687  days  long; 
beyond  Mars  is  a group  of  small  planets  which  are  not  large  enough  to  be 
seen  with  the  telescope,  but  we  know  that  one  of  the  largest  of  the  group  is 
only  490  miles  through;  beyond  this  mysterious  swarm  of  little  worlds  is 
great  Jupiter  almost  ten  times  as  thick  through  as  the  earth,  and  it  is  so  far 
away  that  it  does  not  circle  about  the  sun  but  once  in  1 1 years ; beyond 
great  Jupiter  comes  Saturn,  not  quite  ten  times  the  diameter  of  the  earth 
and  so  far  from  the  sun  that  it  takes  29^  years  for  it  to  move  around  its 
orbit;  beyond  Saturn  is  Uranus,  only  about  four  times  as  thick  through  as 
our  world,  and  it  has  a year  84  years  long;  but  the  outermost  of  all  our 
sun’s  planets  is  Neptune,  little  larger  than  Uranus,  but  so  far  from  the 
sun  that  165  years  are  required  for  it  to  complete  its  circle.  Just  think 
of  a spring  or  a winter  41  years  long!  If  Methuselah  had  lived  on  Nep- 
tune, he  would  have  died  before  he  was  five  and  one-half  years  old. 

Almost  all  of  the  Earth’s  sister  planets  are  better  off  for  moons  than  she ; 
neither  Venus  nor  Mercury  has  any  moons.  Mars  has  two  moons,  Jupiter 
nine  and  Saturn  has  nine  besides  some  splendid  rings;  strangely,  two  of 
Jupiter’s  and  one  of  Saturn’s  moons  revolve  in  an  opposite  direction  from 
the  others.  Uranus  has  four  moons,  while  Neptune  is  not  any  better 
off  than  we  are,  unless  there  are  some  we  have  not  been  able  to  discover 
because  they  are  so  far  away. 

One  peculiar  thing  about  all  of  the  planets  of  the  sun’s  family  and  all  of 
their  moons  is  that  they  all  shine  by  reflecting  the  light  of  the  sun,  and  none 
of  them  are  hot  enough  to  give  off  light  independently;  but  these  sister 
worlds  of  ours  are  so  near  us  that  they  often  seem  larger  and  brighter  than 
the  stars,  which  are  true  suns  and  give  off  much  more  light  than  our  own 
sun.  After  a little  experience  the  young  astronomer  learns  to  distinguish 
the  planets  from  the  true  stars ; the  planets  always  follow  closely  the  path 
of  the  sun  and  moon  through  the  sky;  they  often  seem  larger  and  brighter 
than  the  true  stars  and  do  not  twinkle  so  much.  The  so-called  morning 
and  evening  stars  are  other  planets  of  our  sun’s  family  and  are  not  stars  at 
all. 

Dr.  Simon  Newcomb  in  his  delightful  book,  “Astronomy  for  Every- 
body,” gives  the  best  illustration  to  make  us  understand  the  place  of  our

sun  and  its  planets  and  its  relation  to  the  stars  in  space.  He  explains  that 
if  here  in  the  Atlantic  States  we  should  make  a model  of  our  solar  system  by 
putting  an  apple  down  in  a field  to  represent  the  sun ; then  our  earth  could 
be  represented  by  a mustard  seed  forty  feet  away  revolving  around  the 
apple;  and  Neptune,  our  outermost  planet,  could  be  represented  as  a small 
pea  circling  around  the  apple  at  the  distance  of  a quarter  of  a mile.  Thus, 
our  whole  solar  system  could  be  modeled  in  a field  one-half  mile  square, 
except  for  comets  which  might  extend  out  in  their  long  orbits  for  several 
miles.  But  to  find  the  star  nearest  to  our  earth,  the  stai  that  is  only  four 
and  one-half  light-years  away  from  us,  we  should  have  to  travel  from  this 
field  across  the  whole  of  North  America  to  California,  and  then  take  steamer 
and  go  out  into  the  Pacific  Ocean  before  we  should  reach  our  nearest  star 
neighbor,  which  would  be  another  sun  like  our  own  and  be  represented  by 
another  apple. 

Comets 

Besides  planets  and  stars  there  are  in  space  other  bodies  spinning  around 
our  great  sun,  and  following  paths  shaped  quite  differently  than  those 
followed  by  our  earth  and  its  sister  planets.  We  move  around  the  sun 
nearly  in  a circle  with  the  sun  at  the  center,  but  these  other  heavenly  bodies 
move  in  narrow  oval  orbits,  the  sun  being  near  one  end  of  the  ellipse  and 
the  other  end  being  out  in  space  beyond  our  farthest  planet.  These  bodies 
do  not  revolve  around  the  sun  in  the  same  plane  as  our  world  and  the  other 
planets;  indeed  they  often  move  in  quite  the  opposite  direction.  The 
most  noticeable  of  these  bodies  whose  race-track  around  the  sun  is  long 
instead  of  circular  are  the  comets,  and  we  know  that  some  of  these  almost 
brush  the  sun  when  turning  at  the  end  of  their  course.  The  astronomers 
have  been  able  to  measure  the  length  of  the  race-tracks  of  some  of  the 
comets  and  thus  tell  when  they  will  come  back.  Encke’s  comet,  named 
after  the  German  astronomer,  makes  its  course  in  three  and  one-half  years 
and  this  is  the  shortest  period  of  any  we  know.  There  are  five  hundred 
comets  whose  courses  have  been  thus  measured ; the  longest  period  belongs 
to  Halley’s  comet,  which  makes  such  a long  trip  that  it  comes  back  only 
once  in  seventy-six  years;  but  there  are  other  comets  which  astronomers 
are  sure  travel  such  long  routes  that  the]’  come  back  only  once  in  hundreds 
or  even  thousands  of  years.  About  twelve  hundred  comets  have  been  dis- 
covered, many  of  them  so  small  that  they  can  only  be  seen  through  the 
aid  of  the  telescope;  and  it  has  been  found  that  in  one  instance,  at  least, 
three  comets  are  racing  around  the  sun  on  the  same  track. 

A comet  is  a beautiful  object,  usually  having  a head  which  is  a point  of 
brilliant  light  and  a long,  flaring  tail  of  fainter  light,  which  always  extends 
out  from  it  on  the  side  opposite  the  sun.  The  head  of  a comet  must  be 
nearly  twice  as  thick  through  as  the  earth  in  order  to  be  large  enough  for 
our  telescopes  to  discover  it.  Some  of  the  comet  heads  have  been  measured, 
and  one  was  thirty-one  times,  and  another  one  hundred  and  fifty  times, 
as  wide  as  our  earth.  If  the  heads  are  this  large,  imagine  how  long  the 
tails  must  be!  Some  of  them  are  far  longer  than  the  distance  from  our 
earth  to  the  sun.  The  comet  head  decreases  as  it  approaches  the  sun. 

The  head  of  a comet  is  supposed  to  be  a swarm  of  meteors  with  some 
gas,  glowing  partly  by  reflected  light  and  partly  by  the  sun’s  radiation. 
In  fact,  this  gas  has  so  little  weight  that  light  can  push  it;  one  would 
never  believe  that  light  could  push  anything,  because  we  cannot  feel  it 


go8

strike  against  us;  but  the  physicists  have  found  that  it  does  push,  and  by 
pushing  against  the  particles  of  the  gas  of  comets  it  sends  them  out  into  a 
streamer  away  from  the  sun,  just  as  the  heat  pushes  out  a flaring  cloud  of 
steam  from  the  spout  of  a teakettle. 

Comets  have  played  an  important  part  in  history ; they  were  formerly 
considered  signs  of  the  approval  or  wrath  of  God.  The  comet  appearing 
in  1066  struck  terror  to  the  Saxons  and  presaged  the  Norman  conquest 
of  England.  The  comet  of  18 11  was  thought  to  warn  us  of  the  war  of 
1812  and  Napoleon  of  his  coming  defeat.  This  was  a wonderful  comet 
illuminating  our  skies  for  a year  and  a half;  its  rosy  head  was  veiled  in 
a gaseous  sphere  one  hundred  and  twenty  miles  across  and  its  tail  was 
one  hundred  and  thirty  million  miles  long.  Some  comets  that  have 
failed  to  appear  when  expected  have  their  orbits  marked  by  swarms  of 
meteors. 

Since  comets  are  moving  around  the  sun  in  every  direction,  it  is  possible 
that  the  earth  may  sometime  meet  one ; and  if  this  proves  to  be  a “head  on 
collision”  there  are  those  who  prophesy  that  there  will  be  no  people  left  to 
tell  the  story;  but  the  tails  of  comets  are  so  thin  and  ethereal  that  our 
earth  actually  passed  through  one  once,  and  no  one  but  the  astronomers 
knew  anything  about  it. 

Shooting  Stars 

When  we  look  up  during  an  evening  walk  and  see  a star  falling  through 
space,  sometimes  leaving  a track  of  light  behind  it,  we  wonder  which  of  the 
beautiful  stars  of  the  heavens  has  fallen.  But  astronomers  tell  us  that  no 
real  star  ever  fell,  but  that  what  we  saw  was  a lump  of  the  matter  of  which 
worlds  and  comets  are  made;  and  it  was  following  its  own  swift  path 
around  the  sun,  when  by  chance  it  crossed  our  earth’s  path,  and  there  was 
a collision.  Luckily  for  us  we  were  the  larger  of  the  two  colliding  bodies, 
and  luckier  still  for  us  is  the  fact  that  our  earth  is  surrounded  by  some 
miles  of  air,  else  we  should  be  helpless  under  this  meteoric  bombardment. 
Although  this  shooting  star  was  just  a dark,  cold  lump  of  metal,  too  small 
for  us  to  see,  yet  it  was  moving  so  swiftly  along  its  path  around  the  sun 
that  the  friction  caused  by  its  passing  through  our  air,  lighted  it  and  burned 
it  up,  just  as  a match  scratched  on  sandpaper  lights  and  burns;  as  soon 
as  it  blazed  we  saw  it  and  said,  “There  is  a shooting  star!”  Sometimes 
the  lump  is  so  big  that  it  does  not  have  time  to  burn  up  while  passing 
through  the  hundred  miles  or  more  of  our  atmosphere,  and  what  is  left 
of  it  strikes  the  earth  usually  with  such  force  as  to  bury  itself  deep  in  the 
soil.  Such  lumps  are  called  “meteoroids”  before  they  fall  and  “meteors” 
while  plunging  white-hot  through  the  air,  but  when  they  reach  our  earth 
we  call  what  is  left  of  them  “meteorites.”  There  are,  in  museums,  many 
meteorites  of  this  so-called  stone,  which  is  largely  iron.  Chemists  find 
no  new  metals  or  elements  in  these  strangers  from  space,  but  they  do  find 
new  kinds  of  chemical  partnerships  and  combinations.  Some  of  these 
meteorites  weigh  hundreds  of  pounds,  one  in  the  Yale  Museum  weighing 
1635  pounds.  If  it  were  not  for  the  air  that  wraps  our  globe,  like  a 
great,  kindly  blanket,  and  by  its  friction  sets  fire  to  the  meteors  and 
destroys  them,  no  one  could  live  on  this  earth  because  we  all  should  be 
pelted  to  death.  Prof.  Newton  estimated  that  every  twenty-four  hours 
our  world  meets  seven  millions  of  these  shooting  stars,  some  of  them 
no  larger  than  shot  and  others  weighing  tons.

The  Relation  Between  Comets  and  Meteors 

It  has  been  discovered  that  many  of  the  shooting  stars  are  gathered  in 
great  flocks  and  move  about  the  sun  in  elongated  paths,  like  the  comets. 
We  have  learned  the  times  of  year  when  the  path  our  earth  follows  comes 
close  to  these  flocks  of  meteors  which  are  flying  around  the  sun  like  birds. 
One  of  these  flocks  is  straggling,  and  we  begin  to  meet  it  about  the  end  of 
July  and  reach  the  center  of  the  crowd  on  August  10th,  and  then  continue 
to  take  stragglers  until  the  last  of  August.  We  can  see  the  point  where  we 
meet  this  flock  of  meteors,  if  we  look  for  it  in  the  direction  of  the  constella- 
tion Perseus  (see  planisphere).  On  November  13th,  we  meet  another  flock 
which  we  find  in  the  direction  of  the  constellation  Leo,  of  which  the  great 
star  Regulus  is  the  heart  (see  chart) ; but  this  flock  is  usually  all  in  a bunch 
and  we  pass  it  in  two  days.  Once  there  was  a splendid  flock  which  our 
world  met  every  thirty-three  years,  and  we  took  so  many  stragglers  from  it 
that  our  skies  were  filled  with  shooting  stars,  and  ignorant  people  were 
greatly  frightened ; but  for  some  reason,  this  flock  has  changed  its  path  and 
we  looked  in  vain  for  the  great  display  of  fireworks  which  was  due  to  occur 
in  1899. 

While  we  know  from  observation  that  the  flocks  of  shooting  stars,  which 
make  our  star  showers,  are  just  broken  pieces  of  comets  which  once  traveled 
the  same  path,  yet  it  does  not  follow  that  all  our  shooting  stars  are  comet 
fragments.  Prof.  Elkins  has  shown  by  photographing  meteors  that  some 
of  them  must  be  wanderers  in  the  vast  spaces  which  lie  between  the  stars. 


* THE  RELATION  BETWEEN  THE  TROPIC  OF  CANCER  AND 
THE  PLANTING  OF  THE  GARDEN 
By  John  W.  Spencer 
A story  to  be  read  to  the  pupils 

In  years  gone  by,  many  farmers  had  a favorite  phase  of  the  moon  when 
they  planted  certain  crops,  usually  spoken  of  as  the  “dark”  or  the  “light”  of 
the  moon.  I once  knew  a woman  who  picked  her  geese  by  the  “sign  of  the 
moon.  ’ ’ Hogs  were  butchered  in  the  ‘ ‘light”  of  the  moon,  and  then  the  pork 
would  not  “fry  away”  so  much  in  the  skillet.  It  is  true  some  pork  from 
some  hogs  wastes  faster  than  that  of  others,  but  the  difference  is  due  to  the 
kind  of  food  given  the  hogs.  Many  farmers  hold  to  those  old  superstitions 
yet,  but  the  number  is  much  less  now  than  twenty-five  years  ago.  I wish  I 
might  impress  on  you  young  agriculturists  that  the  moon  has  no  influence 
on  plant  life,  or  pork,  or  geese,  but  the  position  of  the  sun  most  decidedly 
has.  We  have  some  plants  that  had  best  be  planted  when  the  sun’s  rays 
strike  the  state  of  New  York  slantingly,  which  means  in  early  spring  or  late 
fall.  We  have  other  plants  that  should  not  be  put  in  the  open  ground  until 
the  rays  of  the  sun  strike  the  state  more  direct  blows,  which  means  the  hotter 
weather  of  summer.  If  I were  in  close  touch  with  you  pupils,  I should  be 
glad  to  tell  some  things  that  happen  to  three  young  friends  of  mine,  hoping 
that  thereby  my  statement  might  give  the  boys  and  girls  an  interest  in  three 
geographical  lines  concerning  the  tropics,  and  lead  them  to  find  their  loca- 
tion on  the  map,  particularly  when  later  they  learn  what  happens  to  my

three  young  friends,  whom  we  will  call  by  the  following  names:  There  is 
one  in  Quito,  Ecuador,  of  whom  we  will  speak  as  Equator  Shem;  the  one  on 
the  Island  of  Cuba  is  named  Tropic  of  Cancer  Ham;  and  the  other  in  San 
Paulo,  Brazil,  answers  to  the  name  of  Tropic  of  Capricorn  Japhet. 

What  happens  to  these  three  boys,  Shem,  Ham  and  Japhet,  is  this.  At 
certain  times  of  the  year  they  have  no  shadow  when  they  go  home  for  dinner 
at  noon.  This  state  of  affairs  is  no  fault  of  theirs.  It  is  not  because  they 
are  too  thin  to  make  shadows.  It  is  due  to  the  position  of  the  sun.  ' If  the 
boys  should  look  for  that  luminary  at  noon,  they  would  find  it  as  directly 
over  their  heads  as  a plumb  line.  It  is  a case  of  direct  or  straight  blows  from 
rays  of  the  sun,  and,  oh,  how  hot — hotter  than  any  Fourth  of  July  the  oldest 
inhabitant  can  remember!  These  three  boys  are  not  hit  squarely  on  the 
head  on  one  and  the  same  day.  Each  is  hit  three  months  after  the  other. 
The  first  boy  to  be  hit  this  year  in  the  above  manner  will  be  the  Equator 
Shem.  The  time  will  be  during  the  last  half  of  March.  Can  any  of  my 
young  friends  in  this  grade  tell  me  the  exact  day  of  March  that  Equator 
Shem  has  no  shadow?  If  no  one  of  you  can  answer  that  question  at  this 
time,  you  had  best  talk  it  over  with  your  friends,  and  bring  your  answers 
tomorrow.  It  happens  at  a time  when  our  days  are  of  about  equal  length. 

Another  thing  about  this  particular  day  is  that  our  almanacs  call  it  the 
first  day  of  spring.  All  because  no  boy  or  anything  else  has  a shadow  on  the 
equator  at  noon  time.  People  and  bluebirds  and  robins  in  the  state  of  New 
York  will  see  squalls  of  snow  about  that  time,  and  there  will  be  some  freez- 
ing nights.  But  after  the  first  day  of  spring  the  cold  storms  do  not  last  so 
long,  as  was  the  case  during  December,  January,  and  early  February,  when 
the  sun’s  rays  hit  us  with  very  glancing  blows.  Watch  to  see  how  much 
faster  the  sun  melts  the  snow  on  the  last  days  of  March  than  it  did  at 
Christmas  time.  The  light  is  also  stronger  and  brighter,  and  plants  in 
greenhouses  and  our  homes  have  more  life,  and  are  not  so  shiftless,  so  to 
speak.  Even  the  hens  feel  the  influence,  for  they  begin  to  lay  more  eggs  and 
cackle,  and  down  goes  the  price  of  eggs.  Do  not  forget  to  learn  what  day  in 
March  spring  begins,  when  the  Equator  boy  finds  it  so  hot  that  he  would  like 
to  take  off  his  flesh,  and  sit  in  his  bones.  After  a few  days,  Equator  Shem 
will  find  he  again  has  a shadow  at  noon.  A short  one  it  is  true,  but  it  will  get 
longer  and  longer  each  day.  N ow  his  shadow  will  be  on  the  south  side  of  him. 
Is  this  a queer  thing  to  happen  ? On  which  side  of  you  is  your  noon-time 
shadow  ? I will  give  every  one  of  you  a red  apple  that  finds  it  anywhere  but 
on  the  north  side  of  him  at  twelve  o’clock.  Every  time  the  sunshines  at 
noon,  watch  to  find  your  old  uncle  in  the  wrong,  and  thereby  get  the  apple. 
Each  day  that  the  shadow  of  Equator  Shem  becomes  longer  and  longer,  the 
noon-day  shadow  of  Tropic  of  Cancer  Ham  , living  on  the  Island  of  Cuba,  will 
be  getting  shorter  and  shorter,  until  at  last  there  comes  a day  during  the  last 
of  June  that  he,  too,  will  have  no  shadow,  and  the  almanac  says  that  that 
day  is  the  beginning  of  summer. 

Now  it  will  be  the  turn  of  the  Tropic  of  Cancer  Ham,  on  the  Island  of 
Cuba,  to  say  the  weather  is  hotter  than  two  Fourths  of  July  beat  into  one, 
and  he  too  will  wish  that  he  could  take  off  his  flesh,  and  sit  in  his  bones. 
Everybody  in  the  state  of  New  York  will  say  that  the  first  summer  day  is 
the  longest  day  of  the  year.  It  is  on  this  day  that  Equator  Shem  will  have 
as  long  a shadow  as  he  ever  had  in  his  life.  No  United  States  boy  will  ever 
be  without  a shadow  at  noon  so  long  as  he  remains  in  his  own  country.

bed,  it  will  yet  be  light  enough  to  read  the  papers.  The  sun  not  only  sets 
late  on  that  first  summer  day,  but  it  appears  early  next  morning.  What  a 
beautiful  spectacle  a sunrise  in  June  is ! Men  of  wealth  will  pay  thousands 
of  dollars  for  pictures  showing  its  glory,  yet  I suppose  that  not  one  boy  in 
five  hundred  ever  saw  the  beauty  of  the  birth  of  a new  day  in  the  sixth 
month  of  the  year,  and  with  no  price  of  admission  at  that. 

For  only  one  day  do  the  sun’s  rays  fall  directly  on  top  of  the  head  of 
Tropic  of  Cancer  Ham,  who  lives  on  the  Island  of  Cuba — just  for  one  day, 
after  which  the  up  and  down  rays  travel  back  towards  the  Equator  Shem. 
On  the  twenty-first  of  September  Shem  again  has  no  shadow  at  noon,  and 
the  almanac  makers  say  that  is  the  last  day  of  summer,  and  tomorrow  will 
be  the  first  day  of  autumn.  Again  it  is  very  hot  where  Shem  lives,  but  the 
alligators  and  monkeys  and  the  parrots  do  not  seem  to  mind  it.  Where  do 
the  up  and  down  rays  of  the  sun  go  next  ? They  keep  going  south,  hunting 
for  the  boy  named  Tropic  of  Capricorn  Japhet,  to  warm  him  up,  as  was  the 
case  with  the  boys  in  Cuba  and  at  the  Equator.  The  up  and  down  rays  do 
not  find  the  top  of  the  head  of  the  lad  in  the  City  of  San  Paulo,  Brazil  until 
the  last  part  of  December,  just  four  days  before  Christmas,  and  then  the 
almanac  says  this  is  the  beginning  of  winter,  and  the  shorter  days  of  the 
year,  when  we  in  the  state  of  New  York  light  the  lamp  at  five  o’clock  in  the 
afternoon.  Now,  my  boys  and  girls,  do  you  understand  why  we  have  a 
change  of  seasons  ? Do  you  understand  that  the  sun  changes  his  manner  of- 
pitching  his  rays  at  us?  That  in  winter,  when  he  is  over  the  head  of  the 
Tropic  of  Capricorn  Japhet  in  San  Paulo,  and  making  summer  on  that  part 
of  the  earth,  to  us  people  in  the  north,  in  the  State  of  New  York,  he  pitche ; 
only  slanting  rays  that  do  not  hit  us  hard,  and  have  but  little  power  ? Thus 
you  will  see  that  the  rays  of  the  sun  that  strike  the  earth  direct  blows,  swing 
back  and  forth  like  a pendulum,  year  after  year,  and  century  after  century, 
coming  north  as  far  as  Tropic  of  Cancer  Shem,  but  no  farther,  and  then 
swinging  south  as  far  as  the  boy  named  Tropic  of  Capricorn  Japhet,  and  no 
farther,  just  stopping  and  swinging  back  again  towards  the  north. 


THE  ZODIAC  AND  ITS  SIGNS 
Teacher's  Story 

To  be  retold  to  pupils. 

The  mysterious  symbols  of  the  Zodiac  on  the  first  pages  of  almanacs  are 
always  a source  of  wonder  and  awe  to  children,  and  remain  a life-long 
mystery  to  most  people  except  fortune  tellers;  and  yet  the  Zodiac  is  the 
simplest  thing  in  the  world  to  understand.  However,  the  lesson  should 
not  be  given  until  after  the  children  have  had  their  lessons  on  the  sun  and 
the  shadow-stick,  and  also  the  lessons  on  the  stars. 

The  ancients  who  believed  the  earth  stood  still  and  the  sun  moved  around 
it,  noticed  inevitably  that  the  path  through  the  heavens  pursued  by  the  sun 
reached  in  summer  a point  farther  north  and  higher  up  than  in  the  winter, 
and  they  naturally  wished  to  map  this  path,  so  as  to  fix  it  in  their  minds  and 
writings.  Nothing  could  be  easier,  for  there  in  the  skies  were  the  eternal 
stars  always  following  the  same  fixed  path  through  the  heavens  and  never 
wobbling  up  and  down  like  the  sun.  So  they  chose  the  constellation  which 
marked  the  highest  point  in  the  sun’s  path  for  each  month,  and  these  con- 
stellations might  be  likened  to  a stairway  with  six  steps  down  toward  the 


912

south  and  six  steps  up  toward  the  north,  the  highest  stair  being  reached  by 
the  sun  in  June,  for  then  the  sun  is  highest  in  the  heavens  and  the  farthest 
north.  So  beginning  in  June  with  Cancer,  (the  Crab) , which  is  high  in  the 
heavens,  it  steps  down  to  Leo,  (the  Lion)  in  July,  takes  another  step  lower 
to  the  Virgin  in  August,  another  down  to  the  Scorpion  in  September,  and 
comes  to  the  lowest  step  of  all,  Sagittarius,  (the  Archer),  in  November;  for 
at  the  last  of  November,  the  sun’s  path  reaches  its  lowest  point  farthest 
south  in  the  heavens  and  then  the  days  are  shortest.  But  in  December  it 
begins  to  climb  and  takes  a short  step  up  to  Capri  cornus,  (the  Goat) , in 
January  it  rises  to  Aquarius,  (the  Water  Carrier),  and  in  February  rises 
another  step  to  Pisces,  (the  Fishes).  In  March  it  reaches  up  to  Aries,  (the 
Ram) , in  April  attains  Taurus,  (the  Bull) , and  in  May  reaches  Gemini,  (the 
Twins),  which  step  is  almost  as  high  and  as  near  to  the  North  Star  as  was 
the  Cancer,  where  the  journey  began  the  June  before. 

It  may  be  difficult  for  the  pupils  to  learn  to  know  all  these  constellations, 
as  some  of  them  are  not  very  well  marked;  however,  if  they  wish  to  learn 
them  they  can  do  so  by  the  use  of  the  planisphere.  Some  of  the  Zodiac 
constellations  are  marked  by  brilliant  stars  which  have  already  been  learned. 
Regulus  is  the  heart  of  Leo,  the  Lion ; Spica  which  means  “ear”  is  the  ear  of 
wheat  which  the  Virgin  is  holding  in  the  constellation  Virgo.  Red  Antares 
lies  in  the  Scorpion;  and  the  Milk  Dipper,  which  is  shaped  like  the  Big 
Dipper,  but  smaller,  marks  Sagittarius.  Red  Aldsbaran  is  the  fiery  eye  of 
Taurus,  the  Bull,  while  the  Gemini,  or  Twins,  are  the  most  conspicuous  of 
the  stars  in  the  evening  skies  of  February  and  March.  It  should  be  noted, 
however,  that  at  the  present  day,  owing  to  the  peculiar  movement  of  our 
earth,  the  path  of  the  sun  in  climbing  up  and  down  these  constellation 
steps  is  not  quite  the  same  as  it  seemed  to  the  ancients.

THE  RELATIONS  OF  THE  SUN  TO  THE  EARTH 

Teacher's  Story 

“ Whether  we  look  or  whether  we  listen, 

We  hear  life  murmur  or  see  it  glisten 

— Lowell. 

All  this  murmuring  and  glistening  life  on  our  earth  planet  has  its  source 
in  the  great  sun  which  swings  through  our  skies  daily,  sending  to  us  through 
the  friendly  ether  his  messages  of  light  and  warmth — messages  that  kindle 
life  in  the  seed  and  perfect  the  existence  of  every  living  organism,  whether  it 
be  the  weed  in  the  field  or  the  king  on  his  throne. 

At  sunrise  this  heat  which  the  sun  sends  out  equally  at  all  times  of  day 
and  night,  is  tempered  when  it  reaches  us  because  it  passes  obliquely  through 
our  atmosphere-blanket,  and  thus  traverses  a greater  distance  in  the  cooling 
air..  The  same  is  true  at  sunset ; but  at  noon,  when  the  sun  is  most  directly 
over  our  heads  its  rays  pass  through  the  least  possible  distance  of  the  at- 
mosphere-blanket and,  therefore,  lose  less  heat  on  the  way.  It  is  true  that 
often  about  three  o’clock  in  the  afternoon  is  the  hottest  period  of  the  day, 
but  this  is  because  the  air-blanket  has  become  thoroughly  heated;  but  we 
receive  the  most  heat  directly  from  the  sun  at  noon. 

The  variations  in  the  time  of  the  rising  and  the  setting  of  the  sun  may  be 
made  a most  interesting  investigation  on  the  part  of  the  pupils.  They 
should  keep  a record  for  a month  in  the  winter ; and  with  this  as  a basis,  use 
the  almanac  to  complete  the  lesson.  Thus,  each  one  may  learn  for  himself 
which  is  the  shortest  and  which  the  longest  day  of  the  year.  There  is  a 
slight  variation  in  different  years ; the  shortest  day  of  the  year  when  this 
lesson  was  written,  as  computed  from  a current  almanac,  was  the  2 2d  of 
December ; it  was  nine  hours  and  fourteen  minutes  long.  The  longest  day 
of  the  year  was  the  2 2d  of  June,  and  it  was  fifteen  hours  and  six  minutes  in 
duration. ' On  the  longest  day  of  the  year  the  sun  reaches  its  farthest  point 
north  and  is,  therefore,  most  nearly  above  us  at  mid-day.  On  the  shortest 
day  of  the  year,  the  sun  reaches  its  farthest  point  south  and  is,  therefore, 
farther  from  the  point  directly  above  us  at  mid-day  than  during  any  other 
day  of  the  year. 

Also  the  movement  of  the  sun  north  and  south  is  an  interesting  subject 
for  personal  investigation,  as  suggested  in  the  lesson.  Through  quite 
involuntary  observation,  I have  become  so  accustomed  to  the  arc  traversed 
by  the  points  of  sunrise  as  seen  from  my  home,  that  I can  tell  what  month 
of  the  year  it  is,  by  simply  noting  the  place  where  the  sun  rises.  When 
it  first  peeps  at  us  over  a certain  pine  tree  far  to  the  south,  it  is  Decem- 
berwhen  it  rises  over  the  reservoir  it  is  February  or  October;  and  when  it 
rises  over  Beebe  pond  it  is  July.  Only  at  the  equinox  of  spring  and  fall  does 
it  rise  exactly  in  the  east  and  set  directly  in  the  west.  Equinox  means  equal 
nights,  that  is,  the  length  of  the  night  is  equal  to  that  of  the  day. 

So  vast  is  the  weight  of  the  sun  that  the  force  of  gravity  upon  its  surface 
is  so  great  that  even  if  it  were  not  for  the  white-hot  fireworks  there  so  con- 
stantly active,  we  could  not  live  upon  it,  for  our  own  weight  would  crush  us 
to  death.  • But  this  multiplying  the  weight  of  common  objects  by  twenty- 
seven  and  two-thirds  to  find  how  much  they  would  weigh  on  the  sun  is  an 
interesting  diversion  for  the  pupils,  and  incidentally  teaches  them  how  to 
weigh  objects,  and  something  about  that  mysterious  force  called  gravity ; 
and  it  is  also  an  excellent  lesson  in  fractions.

LESSON  CCXXXII 

The  Relation  of  the  Sun  to  the  Earth. 

Leading  thought — The  sun  which  is  the  source  of  all  our  light  and  heat 
and,  therefore,  of  all  life  on  our  globe  travels  a path  that  is  higher  across  the 
sky  in  June  than  the  path  which  it  follows  in  December,  and  hence  we 
experience  changes  of  seasons.  The  lesson  should  be  given  to  the  pupils  of 
the  upper  grades  and  should  be  correlated  with  reading,  arithmetic  and 
thinking. 

Observations — 1.  What  does  the  sun  do  for  us? 

2 . At  what  time  of  the  day  after  the  sun  rises  do  we  get  the  least  heat 
from  it  ? What  hour  of  the  day  do  we  get  the  most  heat  from  it  ? 

3.  Is  the  sun  equally  hot  all  day?  Why  does  it  seem  hotter  to  us  at 
one  time  of  the  day  than  at  another? 

4.  At  what  hour  does  the  sun  rise  and  set  on  the  first  of  the  following 
months;  February,  March,  Arpil,  May  and  June? 

5 . Which  is  the  shortest  day  of  the  year,  and  how  long  is  it  ? 

6.  Which  is  the  longest  day  of  the  year,  and  how  many  hours  and 
minutes  are  there  in  it? 

7.  What  day  of  the  year  is  the  sun  nearest  a point  directly  over  our 
heads  at  mid-day? 

8.  Which  day  of  the  year  is  the  sun  at  mid-day  farthest  from  the  point 
directly  above  our  heads?  Explain  why  this  is  so. 

9.  Standing  in  a certain  place,  mark  by  some  building,  tree  or  other 
object  just  where  the  sun  rises  in  the  east  and  sets  in  the  west  on  the  first  of 
February.  Observe  the  rising  and  setting  of  the  sun  from  the  same  place 
on  the  first  day  of  March  and  again  on  the  first  of  April.  Does  it  rise  and 
set  in  the  same  place  always  or  does  it  move  northward  or  southward  ? 

10.  Is  the  sun  farthest  south  on  the  shortest  day  of  the  year?  If  so,  is 
it  farthest  north  on  the  longest  day  of  the  year  ? 

11.  At  what  time  of  the  year  does  the  sun  rise  due  east  and  set  due 
west? 

12.  The  sun  is  so  much  larger  than  the  earth  that  its  force  of  gravity 
is  twenty-seven  and  two-thirds  times  that  of  the  earth.  How  much  would 
your  watch  weigh  if  you  were  living  on  the  sun?  How  much  would  you 
yourself  weigh  if  you  were  there? 

13 . Experiment.  A shadow  stick — Place  a peg  two  or  three  inches  high 
upright  in  a board  and  place  the  board  lengthwise  on  the  sill  of  a south 

window  or  where  it  will  get  the 
south  light.  Note  the  length 
cast  by  the  shadow  of  the  peg 
during  a sunny  day  and  draw  a 
line  with  pencil  or  chalk  out- 
lining the  tip  of  the  shadow  of 
the  stick  from  9 a.  m.  to 
4 p.  m.  Make  a similar  out- 
line a month  later  and  again  a 
month  later  and  note  whether  the  shadow  traces  the  same  line  during 
each  of  these  days  of  observation.  Note  especially  the  length  of  the 
shadow  at  noon.

Another  excellent  observation  lesson  for  teaching  the  fact  that  the  sun 
travels  farther  south  in  the  winter,  is  to  measure  the  shadow  of  a tree  on  the 
school  grounds  at  noonday  once  a month  during  the  school  year.  The 
length  of  the  tree  shadow  can  be  measured  from  the  base  of  the  tree  trunk,  a 
memorandum  being  made  of  it. 

14.  When  does  the  stick  or  tree  cast  its  longest  shadow  at  noon — in 
December  or  February ? February  or  April?  April  or  June?  Why?

LESSON  CCXXXIII 
How  to  Make  a Sundial 

Method — The  diagram  for  the  dial  is  a 
lesson  in  mechanical  drawing.  Each  pupil 
should  construct  a gnomon  ( no-mon ) of 
cardboard,  and  should  make  a drawing  of 
the  face  of  the  dial  upon  paper.  Then  the 
sundial  may  be  constructed  by  the  help  of 
the  more  skillful  in  the  class.  It  should  be 
made  and  set  up  by  the  pupils.  A sundial 
in  the  school  grounds  may  be  made  a center 
of  interest  and  an  object  of  beauty  as  well. 

Materials — For  the  gnomon  a piece  of 
board  a half  inch  thick  and  six  inches 
square  is  required.  It  should  be  given 
several  coats  of  white  paint  so  that  it  will 
not  warp.  For  the  dial,  take  a board 
about  14  inches  square  and  an  inch  or  more  thick.  The  lower  edge  may 
be  bevelled  if  desired.  This  should  be  given  three  coats  of  white  paint,  so 
that  it  will  not  warp  and  check. 

To  make  the  gnomon — The  word  gnomon  is  from  a Greek  word  meaning 

“one  who  knows.”  It  is  the  hand  of 
the  sundial,  which  throws  its  shadow 
on  the  face  of  the  dial,  indicating  the 
hour.  Take  a piece  of  board  six 
inches  square,  and  be  very  sure  its 
angles  are  right  angles.  Let  s,  t,  u,  v 
represent  the  four  angles;  draw  on 
it  a quarter  of  a circle  frorr  stou 
with  a radius  equal  to  the  line  vs. 
Then  with  a cardboard  protractor, 
costing  fifteen  cents,  or  by  working  it 
out  without  any  help  except  knowing 
that  a right  angle  is  90°,  draw  the  line 
vw  making  the  angle  at  x the  same  as 
the  degree  of  latitude  where  the  sun- 
dial is  to  be  placed.  At  Ithaca  the 
latitude  is  420,  27'  and  the  angle  at  x

measures  420  27'.  Then  the  board  should  be  cut  off  at  the  line  vw, 
and  later  the  edge  sw  may  be  cut  in  some  ornamental  pattern. 

To  make  the  dial — Take  the  painted  board  14  inches  square  and  find  its 
exact  center,  y.  Draw  on  it  with  a pencil  the  line  A A"  a foot  long  and  one- 
fourth  inch  at  the  left  of  the  center.  Then  draw  the  line  B B"  exactly  par- 
allel to  the  line  A A' ' and  a half  inch  to  the  right  of  it.  These  lines  should 
be  one-half  inch  apart — which  is  just  the  thickness  of  the  gnomon.  If  the 
gnomon  were  only  one-fourth  inch  thick,  then  these  lines  should  be  one- 
fourth  inch  apart,  etc. 

With  a compass,  or  a pencil  fastened  to  a string,  draw  the  half-circle 
A A'  A"  with  a radius  of  six  inches  with  the  point  C for  its  center.  Draw  a 
similar  half-circle  B B'  B"  opposite  with  c'  for  its  center.  Then  draw  the 
half-circle  from  D,  D',  D",  from  c with  a radius  of  five  and  three-quarter 
inches.  Then  draw  similarly  from  c'  the  half-circle  E,  E',  E".  Then  draw 
from  c the  half-circle  F,  F',  F"  with  a radius  of  five  inches  and  a similar  half- 
circle G,  G',  G"  from  c'  as  a center. 

Find  the  points  M,  M'  just  six  inches  from  the  points  F,  G;  draw  the 
line  J,  K through  M,  M'  exactly  at  right  angles  to  the  line  A,  A'.  This  will

mark  the  six  o’clock  point  so  the  figures  VI  may  be  placed  on  it  in  the  space 
between  the  two  inner  circles.  The  noon  mark  XII  should  be  placed  as 
indicated  (the  “X”  at  D,  F,  the  “II”  at  E,  G).  With  black  paint  outline  all 
the  semi-circles  and  figures. 

To  set  up  the  sundial — Fasten  the  base  of  the  gnomon  by  screws  or 
brads  to  the  dial  with  the  point  s of  the  gnomon  at  F,  G,  and  the  point  v 
of  the  gnomon  at  M,  M',  so  that  the  point  W is  up  in  the  air.  Set  the  dial 
on  some  perfectly  level  standard  with  the  line  A,  A"  extending  exactly 
north  and  south.  If  no  compass  is  available,  wait  until  noon  and  set  the 
dial  so  that  the  shadow  from  W will  fall  exactly  between  the  points  A,  B, 
and  this  will  mean  that  the  dial  is  set  exactly  right.  Then  with  a good 
watch  note  the  points  on  the  arc  E,  K',  on  which  the  shadow  falls  at  one, 
two,  three,  four,  and  five  o’clock : and  in  the  morning  the  points  on  the  arc 
J'  D on  which  the  shadow  falls  at  seven,  eight,  nine,  ten  and  eleven  o’clock. 
Draw  lines  from  M to  these  points,  and  lines  from  M'  to  the  points  on  the 
arc  E K'.  Then  place  the  figures  on  the  dial  as  indicated  in  the  spaces 
between  the  two  inner  circles.  The  space  between  the  two  outer  circles 
may  be  marked  with  lines  indicating  the  half  and  quarter  hours.  The 
figures  should  be  outlined  in  pencil  and  then  painted  with  black  paint,  or 
carved  in  the  wood  and  then  painted. 


T wilight,  twilight  of  the  west,

Hanging,  hanging  as  ye  will 
Low  along  the  western  sky,

And  silent  shoreless  vasts  between —

Ye  know  no  longer  strain  or  stress, 

All  passionless  and  passionless.

THE  MOON 
Teacher's  Story 

The  moon  is  in  more  senses  than  one  an  illuminating  object  for  both  the 
earth  and  the  skies.  As  a beginning  for  earth  study  it  is  an  object  lesson, 
illustrating  what  air  and  water  do  for  our  world  and  incidentally  for  us; 
while  as  the  beginning  of  the  study  of  astronomy,  it  is  the  largest  and 
brightest  object  seen  in  the  sky  at  night ; and  since  it  lies  nearest  us,  it  is  the 
first  natural  step  from  our  world  to  outer  space. 

The  moon  is  a little  dead  world  that  circles  around  our  earth  with  one 
face  always  towards  us,  just  as  a hat-pin  thrust  into  an  apple  would  keep 
the  same  side  of  its  head  always  toward  the  apple  no  matter  how  rapidly  the 
apple  was  twirled.  As  we  study  the  face  of  the  moon,  thus  always  turned 
toward  us,  we  see  that  it  is  dark  in  some  places  and  shining  in  others,  and 
some  ignorant  people  have  thought  that  the  dark  places  are  oceans  and  the 
light  places,  land.  But  the  dark  portions  are  simply  areas  of  darker  rocks, 
while  the  lighter  portions  are  yellowish  or  whitish  rocks.  The  dark  portions 
are  of  such  a form  that  people  have  imagined  them  to  represent  the  eyes, 
nose  and  mouth  of  a man’s  face;  but  a far  prettier  picture  is  that  of  a 
woman’s  uplifted  face  in  profile.  The  author  has  a personal  feeling  on  this 
point,  for  as  a child  she  saw  the  man’s  face  always  and  thought  it  very  ugly 
and,  moreover,  concluded  that  he  chewed  tobacco;  but  after  she  had  been 
taught  to  find  the  face  of  the  lady,  the  moon  was  always  a beautiful  object 
to  her. 

The  moon  is  a member  of  our  sun’s  family,  his  granddaughter  we  might 
call  her  if  the  earth  be  his  daughter ; and  since  the  moon  has  no  fires  or  light 
of  its  own,  it  shines  by  light  reflected  from  the  sun  and,  therefore,  one-half 
of  it  is  always  in  shadow.  When  we  see  the  whole  surface  of  the  lighted 
half  we  say  the  moon  is  full;  but  when  we  see  only  half  of  the 


Sky  Study 


9L9 


lighted  side  turned  toward  us,  we 
say  the  moon  is  in  its  quarter, 
because  all  we  can  see  is  one- 
half  of  one-half  which  is  one- 
quarter;  and  when  the  lighted 
side  is  almost  entirely  turned 
away  from  us  we  say  it  is 
a crescent  moon;  and  when 
the  lighted  side  is  entirely 
turned  away  from  us  we  say  there 
is  no  moon,  although  it  is  always 
there  just  the  same.  Thus,  we 
can  understand  that,  although  we 
can  never  see  the  other  side  of  the 
moon,  the  sun  shines  on  all  sides  of 
it.  Our  earth,  like  the  moon, 
shines  always  by  reflected  light  and 
is  almost  four  times  as  wide  as 
the  moon.  Think  what  a splendid  moon  our  earth  must  seem  to  the 
lady  in  the  moon!  When  we  see  the  old  moon  in  the  new  moon’s 
arms,  the  dark  outline  of  the  moon  within  the  bright  crescent  is  visible 
because  of  the  earthshine  reflected  from  it.  Sometimes  pupils  con- 
fuse this  appearance  of  the  moon  with  a partial  eclipse ; but  the  former  is  the 
new  or  old  moon,  which  is  one  edge  of  the  moon  shining  in  the  sunlight,  the 
remainder  faintly  illumined  by  earth  light,  while  an  eclipse  must  always 
occur  at  the  full  of  the  moon  when  the  earth  passes  between  the  sun  and  the 
moon,  hiding  the  latter  in  its  shadow. 

It  is  approximately  a month  from  one  new  moon  to  the  next,  since  it 
takes  twenty-nine  and  one-half  days  for  the  moon  to  complete  its  cycle 
around  the  earth  and  thus  turn  once  around  in  the  sunshine.  Therefore, 
each  moon  day  is  fourteen  and  three-quarter  days  long  and  the  night  is  the 
same  length.  The  moon  always  rises  in  the  east  and  sets  in  the  west,  follow- 
ing pretty  nearly  the  sun’s  summer  path.  The  full  moon  rises  at  sunset  and 
sets  at  sunrise,  but  owing  to  the  movement  of  the  earth  around  the  sun  the 
moon  rises  about  fifty  minutes  later  each  evening ; however,  this  time  varies 
with  the  different  phases  of  the  moon  and  at  different  times  of  the  year. 
This  difference  in  the  time  of  rising  is  so  shortened  in  August,  that  we  have 
several  nights  when  the  full  moon  lengthens  the  day;  and  it  is  called  the 
“harvest  moon,”  because  in  England  it  adds  to  the  hours  devoted  to 
harvesting  the  grain. 

A’  Visit  to  the  Moon 

If  we  could  be  shot  out  from  a Jules  Verne  cannon  and  make  a visit  to 
the  moon,  it  would  be  a strange  experience.  First,  we  should  find  on  this 
little  world,  which  is  only  as  thick  through  as  the  distance  from  Boston  to 
Salt  Lake  City,  mountains  rising  from  its  surface  more  than  thirty  thousand 
feet  high,  which  is  twice  as  high  as  Mt.  Blanc  and  a thousand  feet  higher 
than  the  tallest  peak  of  the  Himalayas ; and  these  moon  mountains  are  so 
steep  that  no  one  could  climb  them.  Besides  ranges  of  these  tremendous 
mountains,  there  are  great  craters  or  circular  spaces  enclosed  with  steep 
rock  walls  many  thousand  feet  high.  Sometimes  at  the  center  of  the  crater 
there  is  a peak  lifting  itself  up  thousands  of  feet,  and  sometimes  the  space 


920  Handbook  of  Nature-Study 

within  the  crater  circle  is  level.  Thirty-three  thousand  of  these  craters 
have  been  discovered.  And,  too,  on  the  moon,  there  are  great  plains  and 
chasms ; and  all  these  features  of  the  moon  have  been  mapped,  measured 
and  photographed  by  people  on  our  earth.  For  a boy  studying  geometry, 
the  measuring  of  the  height  of  the  mountains  of  the  moon  is  an  interesting 
story. 

But  we  could  never  in  our  present  bodies  visit  the  moon,  because  of  one 
terrible  fact — the  moon  has  no  air  surrounding  it.  No  air ! What  does  that 
mean  to  a world?  First  of  all,  as  we  know  life,  no  living  thing — animal  or 
plant — could  exist  there,  for  living  beings  must  have  air.  Neither  is  there 
water  on  the  moon;  for  if  there  were  water  there  would  have  to  be  air. 
And  without  water  no  green  thing  can  be  grown,  and  the  surface  of  the  moon 
is  simply  naked,  barren  rock.  If  we  were  on  the  moon,  we  could  not  turn 
our  eyes  toward  the  sun,  for  with  no  air  to  veil  it,  its  fierce  light  would  blind 
us;  and  the  sky  is  as  black  at  midday  as  at  midnight,  since  there  is  no  at- 
mosphere to  sift  out  the  other  rays  of  light,  leaving  the  beautiful  blue  in  the 
sky ; nor  is  there  a glow  at  sunset  because  there  is  no  air  prism  to  separate 
the  rays  of  light  and  no  clouds  to  reflect  or  refract  them.  The  stars  could 
be  seen  in  the  black  skies  of  midday  as  well  as  in  the  black  skies  of  night,  and 
they  would  be  simply  points  of  light  and  could  not  twinkle,  since  there  is  no 
air  to  diffuse  the  sun’s  light  and  thus  curtain  the  stars  by  day  and  cause 
them  to  twinkle  at  night.  The  shadows  on  the  moon  are,  for  the  same 
reason,  as  black  as  midnight  and  as  sharply  defined;  and  if  we  should  step 
into  the  shadow  of  a rock  at  midday  we  should  be  hidden  although  some 
light  reflected  from  the  rocks  around  us  might  reach  us.  Hiding  in 
such  a shadow  would  be  like  putting  on  the  invisible  cloak  of  fairy  lore.

And  because  of  no  layers  of  air  to  make  an  aerial  perspective,  a mountain 
a hundred  miles  away  would  seem  as  close  to  us  as  one  a mile  away. 

Since  there  is  no  atmosphere  on  the  moon  to  act  as  a buffer  between  the 
cold  of  outer  space,  which  is  estimated  to  be  250°  below  zero,  and  the 
heat  of  the  sun,  which  is  500°  above  zero,  the  temperature  of  the  moon 
reaches  above  boiling  point  at  noon  and  absolute  zero  at  midnight,  be- 
cause there  is  no  air  to  carry  the  heat  over  into  the  shadow  or  to  blanket 
the  moon  at  night.  But  this  great  change  of  temperature  between  sun- 
light and  darkness  is  the  only  force  on  the  moon  to  change  the  shape  of 
its  rocks,  for  the  expansion  under  heat  and  contraction  under  cold  must 
break  and  crumble  even  the  firmest  rock  more  or  less.  Our  rocks  are 
broken  by  the  freezing  of  water  that  creeps  into  every  crevice,  but  there 
is  no  water  to  act  on  the  moon’s  mountains  in  this  fashion  or  to  wear 
them  away  by  dashing  over  their  surface.  However,  the  rocks  and 
mountains  of  the  moon  may  be  changed  in  shape  by  the  battering  of 
meteorites,  which  pelt  into  the  moon  by  the  million,  since  the  moon  has 
no  air  to  set  them  afire  and  make  them  into  harmless  shooting  stars, 
burning  up  before  they  strike.  But  though  a meteorite  weighing  thou- 
sands of  tons  should  crash  into  a moon  mountain  and  shatter  it  to  atoms 
there  would  be  no  sound,  since  sound  is  carried  only  by  the  atmosphere. 

Imagine  this  barren,  dead  world,  chained  to  our  earth  by  links  forged 
from  unbreakable  gravity,  with  never  a breath  of  air,  a drop  of  rain  or  flake 
of  snow,  with  no  streams,  nor  seas,  nor  graced  by  any  green  thing — not  even 
a blade  of  grass — a tree,  nor  by  the  presence  of  any  living  creature ! Out 
there  in  space  it  whirls  its  dreary  round,  with  its  stupendous  mountains 
cutting  the  black  skies  with  their  jagged  peaks  above,  and  casting  their 
inky  shadows  below ; heated  by  the  sun’s  rays  until  hotter  than  the  flame  of 
a blast  furnace,  then  suddenly  immersed  into  cold  that  would  freeze  our  air 
into  solid  ice,  its  only  companion  the  terrific  rain  of  meteoric  stones  driven 
against  it  with  a force  far  beyond  that  of  cannon  balls,  and  yet  with  never  a 
sound  as  loud  as  a whisper  to  break  the  terrible  stillness  which  envelops  it. 

LESSON  CCXXXIV 
The  Moon 

Leading  thought — The  moon  always  has  the  same  side  turned  toward  us 
so  we  do  not  know  what  is  on  the  other  side.  The  moon  shines  by  re- 
flected light  from  the  sun,  and  is  always  half  in  light  and  half  in  shadow. 
The  moon  has  neither  air  nor  water  on  its  surface  and  what  we  call  the 
moon  phases  depend  on  how  much  of  the  lighted  surface  we  see. 

Method — Have  the  pupils  observe  the  moon  as  often  as  possible  for  a 
month,  beginning  with  the  full  moon.  After  the  suggested  experiment,  the 
questions  which  follow  may  be  given  a few  at  a time. 

Experiment  for  recess — Darken  the  room  as  much  as  possible;  use  a 
lighted  lamp  or  gas  jet  or  electric  light  for  the  sun,  which  is,  of  course, 
stationary.  Take  a large  apple  to  represent  the  earth  and  a small  one  to 
represent  the  moon.  Thrust  a hat  pin  through  the  big  apple  to  represent 
the  axis  of  the  earth  and  also  the  axis  about  which  the  moon  revolves.  Tie 
a string  about  a foot  long  to  the  stem  of  the  moon  apple  and  make  fast  the 
other  end  to  the  hat  pin  just  above  the  earth  apple.  Hold  the  hat  pin  in 
one  hand  and  revolve  the  apple  representing  the  moon  slowly  with  the  other

hand  letting  the  children  see  that  if  they  were  living  on  the  earth  apple  the 
following  things  would  be  true : 

1 . Moving  from  right  to  left  when  the  moon  is  between  the  earth  and 
the  sun  it  reflects  no  light. 

2.  Moving  a little  to  the  left  a crescent  appears. 

3 . Moving  a quarter  around  shows  the  first  quarter. 

4.  When  just  opposite  the  lamp,  it  shows  its  whole  face  lighted  turned 
toward  the  earth. 

5 . Another  quarter  around  shows  a half  disc,  which  is  the  third  quarter . 

6.  When  almost  between  the  sun  and  the  earth  the  crescent  of  the  old 
moon  appears. 

7.  Note  that  the  moon  always  keeps  one  face  toward  the  earth. 


Experiment  for  illustrating  the  phases  of  the  moon. 


8 . N ote  that  the  new  moon  crescent  is  the  lighted  edge  of  one  side  of  the 
moon,  while  the  old  moon  crescent  is  the  lighted  edge  of  the  opposite  side. 

9.  Make  an  eclipse  of  the  moon  by  letting  the  shadow  of  the  earth  fall 
upon  it,  and  an  eclipse  of  the  sun  by  revolving  the  moon  apple  between  the 
sun  and  the  earth.  The  earth’s  orbit  and  the  moon’s  orbit  are  such  that 
this  relative  position  of  the  two  bodies  occurs  but  seldom. 

Observations — 1.  Describe  how  the  moon  looks  when  it  is  full. 

2 . What  do  you  think  you  see  in  the  moon  ? 

3.  Describe  the  difference  in  appearance  between  the  new  moon  and 
the  full  moon,  and  explain  this  difference. 

4.  Where  does  the  new  moon  rise  and  where  does  it  set? 

5.  When  does  it  rise  and  when  does  it  set  ? 

6.  Where  and  when  does  the  full  moon  rise  and  where  and  when  does  it 
set? 

7.  How  does  the  old  moon  look? 

8.  Could  the  crescent  moon  which  is  seen  in  early  evening  be  the  old 
moon  instead  of  the  new;  and,  if  not,  why  not? 


Sky  Study  923 

9.  When  and  where  do  we  ordinarily  see  the  old  moon  when  it  is 
crescent  shaped  ? 

10.  Does  the  moon  rise  earlier  or  later  on  succeeding  nights?  What  is 
approximately  the  difference  in  time  of  moonrise  on  two  successive  nights  ? 

1 1 . Do  you  think  we  always  look  at  the  same  side  of  the  moon  ? If  so, 
why? 

12.  Is  more  than  one  side  of  the  moon  luminous  ? Why  ? 

13 . How  many  days  from  one  new  moon  until  the  next  ? 

14.  How  long  is  the  day  on  the  moon  and  how  long  the  night  ? 

15.  How  many  times  does  the  moon  go  around  the  earth  in  a year? 

16.  What  is  the  difference  between  the  disappearance  of  the  old  moon 
and  an  eclipse  of  the  moon?  In  both  cases  the  moon  is  hidden  from  us. 

The  Physical  Geography  of  the  Moon 

Questions  for  the  pupils  to  think  about  and  answer  if  they  can — 17.  Since 
it  has  been  proved  that  there  is  no  air  or  water  on  the  moon,  could  there  be 
any  life  there  ? 

18.  Supposing  you  could  do  without  air  or  water  and  should  be  able  to 
visit  the  moon,  what  would  you  find  to  be  the  color  of  the  sky  there? 

19.  Would  there  be  a red  glow  before  sunrise  or  beautiful  colors  at 
sunset  ? 

20.  Would  the  sun  appear  to  have  rays?  Could  you  look  at  the  sun 
without  being  blinded  ? 

2 1 . Would  the  stars  appear  to  twinkle ? Could  you  see  the  stars  in  the- 
daytime  ? 

2 2 . How  would  the  shadows  look  ? If  you  could  step  into  the  shadow 
of  a rock  at  midday,  could  you  be  seen? 

23 . Could  you  tell  by  looking  at  it  whether  a mountain  was  far  or  near? 

24.  It  is  estimated  that  the  temperature  of  outer  space  is  250  degrees 
below  zero,  and  the  sun’s  direct  heat  is  500  degrees  above  zero.  If  this  be 
correct,  how  hot  would  it  be  in  the  sunshine  on  the  moon?  How  cold 
would  it  be  at  midnight  ? 

25.  Why  is  it  so  much  hotter  and  colder  on  the  moon  than  upon  the 
earth? 

26.  If  you  could  shout  on  the  moon,  how  would  it  sound?  If  one 
hundred  cannons  should  be  fired  at  once  on  the  moon,  how  would  it  sound? 

27.  Is  there  any  rain  or  snow  on  the  moon?  Are  there  any  clouds 
there?  If  there  are  no  air  and  water  on  the  moon,  would  the  intense  heat 
and  the  powerful  cold  affect  the  soils  or  rocks,  as  freezing  and  thawing  affect 
our  rocks  ? 

28.  Professor  Newton  estimated  that  the  earth  meets  seven  million 
meteorites  (shooting  stars)  every  twenty-four  hours.  Why  do  we  not  see 
more  of  these?  What  happens  when  a meteorite  strikes  the  moon? 

29.  The  moon  is  so  small  that  the  force  of  gravity  on  its  surface  is  one- 
sixth  that  on  the  earth’s  surface.  If  a man  can  carry  seventy-five  pounds 
on  his  back  here,  how  much  could  he  carry  on  the  moon?  If  a boy  can 
throw  a ball  one  hundred  yards  here,  how  many  yards  could  he  throw  on  the 
moon  ? If  a boy  can  kick  a football  one  hundred  and  thirty-five  feet  in  the 
air  here,  how  far  could  he  kick  it  on  the  moon?
