ERE  IS  a  unique  and  fascinating  guide  to 
Nature  for  parents  and  cfiildren.  If  you 
have  a  child  aged  four  to  fourteen  and  want 
to  help  him— or  yourself— to  understand  and 
enjoy  the  countless  wonders  of  Nature  all 
about  you,  this  exciting  book  will  show  you 
the  way  quickly,  easily,  and  delightfully.  Over 
100  true-to-life  illustrations  by  outstanding 
artists  and  photographers  make  Nature's  story 
doubly  clear  and  dramatic  throughout. 

It  doesn't  matter  what  part  of  Nature  ap- 
peals to  you  most— this  book  takes  you  out 
exploring  them  all,  in  the  park,  in  the  country, 
at  the  zoo  or  museum,  or  simply  by  looking 
at  the  weather  or  the  skies.  It  tells  you  in 
advance  the  questions  a  child  will  ask  and 
shows  you  how  to  answer  them  so  they  make 
sense.  It  gives  you  ideas  for  trips  and  excur- 
sions, rewarding  nature  hobbies  you  can  share 
with  your  child,  and  nature  stories  that  chil- 
dren love  to  hear,  and  in  many  other  ways 
furnishes  inspiration  and  incentive  for  you  to 
form  closer  bonds  with  your  child  through 
Nature,  and  enrich  both  your  lives. 

This  book  tells  you  and  your  child  what 
you  should  know  about  animals,  tame  and 
wild.  From  the  house  cat  to  the  camel,  the 
lamb  to  the  lion,  the  canary  to  the  eagle,  the 
animals  that  interest  a  child  are  described  here 
—how  they  behave,  what  they  eat,  and  their 
fascinating  oddities.  You  are  introduced  to  the 
pleasurable  hobby  of  bird  watching  and  told 
how  to  recognize  birds  by  their  appearance 
and  songs,  and  how  to  attract  them  to  your 
home.  You  are  given  interesting  information 
galore  to  answer  such  inevitable  questions  as 
"How  do  birds  fly?",  "Can  a  squirrel  ever  find 
the  nuts  it  buries?",  "Can  animals  talk?", 
"What  is  the  difference  between  a  rabbit  and 
a  hare?",  and  many,  many  more. 

Snakes  get  their  due  here.  In  these  pages 
your  child  and  vou  will  discover  how  a  snake

ACKNOWLEDGMENTS 

The  writing  of  this  book  would  have  been  quite  impossible  without 
the  wholehearted  interest  of  my  husband,  Melvin  Shuttlesworth.  His 
excellent  advice  and  suggestions,  as  well  as  practical  helps,  have  been 
invaluable.  I  am  grateful  also  to  Frederick  Drimmer,  editor  of  The 
Greystone  Press,  for  his  guidance  and  enthusiasm  all  along  the  way. 
My  deep  appreciation  goes  also  to  C.  M.  Goethe  of  Sacramento, 
California,  who  through  a  lifetime  of  nature  exploring  has  caused 
innumerable  parents  and  children  to  follow  his  example,  and  whose 
interest  in  my  work  over  many  years  has  been  a  constant  inspiration. 

It  is  impossible  to  express  adequately  my  debt  to  the  American 
Museum  of  Natural  History,  where  my  work  gives  me  the  privilege  of 
discussing  the  various  aspects  of  nature  with  brilliant  scientists  who 
are  devoting  their  lives  to  the  study  of  some  particular  field  of  the 
natural  sciences.  Particularly  am  I  indebted  to  the  following  members 
of  the  Scientific  Staff  who  have  read  and  helpfully  criticized  chapters 
of  this  book:  Dr.  John  T.  Zimmer,  Curator  of  Birds;  T.  Donald  Carter, 
Assistant  Curator  of  Mammals;  Francesca  R.  LaMonte,  Associate  Cura- 
tor of  Fishes;  Bessie  Matalas  Hecht,  Scientific  Assistant,  Amphibians 
and  Reptiles;  John  Pallister,  Research  Associate,  Insects  and  Spiders; 
Farida  A.  Wiley,  Instructor,  Department  of  Education;  Dr.  Henry  K. 
Svenson,  Curator,  Forestry  and  Botany;  Robert  R.  Ccles,  Chairman, 
Astronomy  and  the  Hayden  Planetarium.  Also  my  thanks  to  Dr.  George 
H.  Childs  for  reading  the  section  of  seashore  life,  and  to  Dr.  George  G. 
Goodwin,  Associate  Curator  of  Mammals  for  reading  the  section 
on  whales. 

I  am  grateful  for  the  kind  permission  of  Dr.  Arnold  Gesell  and  of 
Ginn  and  Company  to  include  (in  Chapter  One)  an  excerpt  from 
The  Normal  Child  and  Primary  Education,  by  Arnold  and  Beatrice 
Chandler  Gesell.

Exploring  Nature 
with  Your  Child 


CHAP 


TER  II  What  Nature  Exploring 
Can  Do  for  Your  Child 


HiLDREN  are  natural  explorers.  They  have 
the  true  explorer's  interest  in  their  im- 
mediate surroundings  as  well  as  in  faraway  places,  and  they  are 
eager  to  know  why  things  are  as  they  are.  If  you  are  a  wise  parent, 
you  will  look  upon  these  qualities  in  your  child  as  a  sacred  fire- 
always  to  be  fed,  allowed  to  die  out  never.  An  inquiring  mind  and 
zest  for  living  are  essential  for  a  rich,  interesting,  and  worth-while 
life.  Childhood  is  the  time  to  nourish  and  strengthen  these  fine 
qualities. 

Just  as  your  child  is  a  natural  explorer,  you  are  a  natural  guide. 
You  help  him  find  security  and  a  sense  of  direction  in  the  broad 
and  bewildering  world  that  men  have  made;  so,  too,  you  can 
guide  him  along  nature's  ways— and  give  him  a  happy  outlet  and 
satisfaction  for  his  natural  curiosity  and  exuberance. 

You  can  be  a  fellow  explorer,  too,  enriching  your  own  life  as 
well  as  your  child's.  As  you  look  back  on  your  own  early  years, 
you  may  recall  the  first  time  you  noticed  a  bud  opening  into  a 
flower,  a  bird  building  its  nest,  two  colonies  of  ants  battling  each 
other.  You  may  remember  that  such  intimate  glimpses  of  nature 
gave  you  a  real  thrill.  Now,  as  a  parent,  you  can  find  still  more 
pleasure  in  learning  about  the  ways  of  animals  and  the  wonders 
of  plants  as  you  share  your  observing  with  your  child.  No  need  to 
go  on  a  safari  through  Central  Africa— delightful  discoveries  await 
you  in  your  own  back  yard,  in  city  parks  and  suburban  gardens, 
along  forest  trails  where  you  may  hike,  and  by  the  side  of  lakes 
and  streams  or  the  ocean  where  you  may  vacation.

i8  ]  What  Nature  Exploring  Can  Do  for  Your  Child 

There  is  no  end  to  the  wealth  of  experiences  nature  holds  in 
store  for  you  and  your  child.  In  a  park  you  can  see  squirrels  bury- 
ing nuts,  providing  for  lean  times  in  a  season  of  plenty.  You  may 
observe  a  flock  of  wild  ducks  landing  on  a  park  lake  for  a  stop- 
over in  their  long  flight  from  summer  to  winter  homes.  Bees, 
butterflies,  and  ants  have  strange  and  wonderful  ways  that  you 
and  your  child  can  watch  with  fascination  for  hours. 

The  diversion  nature  offers  you  is  more  exciting  than  any 
invented  by  man,  yet  it  is  close  at  hand  and  costs  you  nothing. 
In  many  suburbs  you  may  look  out  of  the  window  in  the  morning 
and  see  a  woodchuck  nibbling  its  breakfast  in  a  dewy  field,  or  a 
rabbit  scampering  across  the  lawn,  purposefully  headed  for  the 
vegetable  garden.  You  may  watch  spiders  spinning  silken  traps, 
or  see  an  exciting  tug-of-war  between  a  robin  and  an  earthworm. 
In  woodlands  and  meadows,  in  zoos  and  museums,  there  is  even 
more  for  you  to  observe.  No  television,  radio,  or  motion  picture 
producer  could  invest  in  his  productions  the  millions  of  years  that 
nature  has  spent  in  preparing  these  thrilling  spectacles  for  you. 

The  Best  Approach  To  Exploring  Nature 

What  is  the  best  method  of  exploring  nature?  The  answer 
depends  on  the  individual  child,  for  children  vary  in  their 
approach  to  nature's  activities  just  as  they  differ  in  countless 
other  ways.  One  child  is  full  of  curiosity  about  plant  and  animal 
life  from  the  time  he  is  an  infant.  Another  is  absorbed  in  fanciful 
ideas,  while  still  another  has  a  mechanical  bent,  remaining  oblivi- 
ous of  natural  wonders  until  you  bring  them  to  his  attention. 

And  so  exploring  nature  is  not  always  a  simple  matter:  It  is 
not  just  "knowing  all  the  answers"  or  pointing  out  each  tree  or 
bird  that  you  see.  A  background  of  information  is  invaluable,  to 
be  sure,  but  you  must  pass  it  on  in  such  a  way  that  you  do  not 
overwhelm  the  child's  own  modest  discoveries.  Awareness  is  essen- 
tial, but  it  should  not  be  carried  to  a  point  where  your  child 
considers  you  slightly  eccentric.  On  the  whole,  the  successful 
approach  lies  in  encouraging  his  inquisitiveness  and  providing 
opportunities  for  him  to  satisfy  his  curiosity.

We  Learn  from  Nature 

Children  with  a  practical  turn  of  mind  particularly  enjoy 
hearing  about  ways  in  which  man  has  put  nature's  "inventions" 
to  use.  Outstanding  among  these  devices  is  camouflage,  applied 
so  effectively  by  many  birds  and  other  animals  for  their  own 
protection.  This  principle  pointed  the  way  for  the  change  from 
army  uniforms  that  made  soldiers  conspicuous  targets  to  the 
deceptive,  neutral  earth  and  leaf  tones  used  in  battle  nowadays. 

Another  debt  we  owe  nature  is  the  inspiration  of  bird  flight, 
which  has  been  carefully  studied  in  advancing  our  own  conquest 
of  the  air.  Fish  that  swam  in  prehistoric  seas,  and  many  other 
creatures,  have  benefited  from  streamlining— another  principle 
that  we  have  put  to  use  only  recently.  Wasps  were  adept  at  making 
paper  from  wood  fiber  centuries  before  human  beings  learned  the 
technique.  Our  recent  invention  of  radar  is  an  old  story  to  bats, 
which  have  a  somewhat  comparable  system  for  getting  their  bear- 
ings as  they  fly  sightless  through  treacherous  passageways.  These 
are  just  a  few  of  the  lessons  that  the  practical-minded  child— or  any 
child— will  enjoy  having  pointed  out  to  him  as  he  becomes  ac- 
quainted with  nature's  ways. 

Overcoming  Fear 

Exploring  nature  teaches  children  to  overcome  many  baseless 
fears.  Occasionally  you  find  a  boy  or  girl  showing  more  timidity 
than  enjoyment  in  encounters  with  animals.  The  reason  for  this 
may  be  difficult  to  trace,  for  a  child  sometimes  has  experiences 
of  which  his  parents  are  not  aware.  I  saw  a  case  in  point  one  day 
in  a  woodsy  stretch  of  a  large  city  park  where  children  were  play- 
ing unsupervised.  A  big  boy,  hand  outstretched,  started  to  chase  a 
little  fellow,  and  was  fairly  hissing  with  menace: 

"Spider!  Spider!" 

The  smaller  child  was  screaming  in  fright.  My  curiosity  aroused 
as  to  the  size  of  the  creature  inspiring  his  terror,  I  approached  the 
older  boy  and  asked  if  I  might  see  the  spider.  He  gave  me  a  de- 
lighted conspiratorial  smile  and  showed  me  what  was  in  his  hand: 
a  small  flower! 


20  ]  What  Nature  Exploring  Can  Do  for  Your  Child 

"I  just  wanted  to  scare  him,"  he  explained.  "He  didn't  come 
close  enough  to  see  what  I  really  had." 

Meanwhile  something  remarkable  had  happened.  The  younger 
boy  had  not  only  stopped  crying,  but  was  coming  slowly  toward 
us.  My  interest  in  the  "spider"  had  aroused  his  curiosity  and  was 
giving  him  courage  to  at  least  see  what  the  "dangerous"  creature 
looked  like.  It  was  strong  evidence  of  the  influence  of  older  people 
on  a  youngster— to  his  advantage  or  detriment. 

As  we  spend  time  with  children  out-of-doors,  we  become  familiar 
with  the  fears  they  may  have  of  little-known  creatures.  Once  we 
realize  that  these  fears  exist,  it  is  usually  not  difficult  to  set  at 
rest  any  timidity  that  is  really  baseless.  The  remedy  is  simply  to 
give  the  youngster  an  understanding  of  the  dreaded  animal. 

"The  Child  Is  Father  of  the  Man'' 

We  contribute  a  great  deal  to  a  child's  future  happiness  by 
giving  him  a  sympathetic  acquaintance  with  as  much  wildlife  as 
possible.  The  point  is  brought  home  to  us  when  we  meet  an 
adult  who  is  agitated  by  any  number  of  groundless  fears. 

I  remember,  for  example,  a  visit  to  our  woodland  cabin  by  a 
woman  whose  usual  haunts  were  in  New  York.  All  day  long  she 
had  been  enjoying  the  trees  and  flowers,  the  river,  and  glimpses 
of  bird  life;  but  in  the  evening  a  screech  owl's  tremulous  wailing 
whistle  suddenly  shattered  the  quiet.  All  our  explanations  about 
its  being  "only  an  owl"  proved  futile.  Our  visitor  had  been  quite 
unnerved  by  the  unearthly  sound,  and  it  was  obvious  she  could 
hardly  wait  to  return  to  what  to  her  was  the  calming  environment 
of  the  big  city. 

A  few  evenings  later  another  visitor— this  time  a  little  boy  of 
no  more  than  five— heard  the  wail  of  the  screech  owl. 

"What  was  that?"  he  asked. 

We  told  him,  hastily  thinking  of  interesting  facts  that  might 
dispel  his  fears.  But  we  need  not  have  bothered.  As  soon  as  he 
heard  it  was  an  owl,  he  said  wistfully: 

"I  wish  he  would  come  close  so  I  could  hold  him  and  pat  him." 

It  is  pleasant  to  think  how  rich  life  will  be  for  this  child, 


What  Nature  Exploring  Can  Do  for  Your  Child  [21 

growing  up  with  an  acceptance  of  all  the  sounds  and  sights  that 
have  a  rightful  place  in  nature's  scheme.  But  he  did  not  come 
by  this  attitude  through  chance.  His  parents  have  been  giving 
him  a  knowledge  and  understanding  of  wildlife  since  he  was 
three.  They  have  told  him  nature  stories  and  taught  him  nature 
lore  and  hobbies  that  have  widened  his  world  and  made  it  more 
enjoyable.  All  this  will  certainly  contribute  to  a  healthful  serenity 
in  later  years. 

You  will  find  it  easy— and  delightful— to  do  the  same  for  ^^our 
child  or  children.  You  are  building  for  the  future  when  you  instil 
in  your  child  a  true  appreciation  of  nature  and  outdoor  activities. 
No  one  who  has  this  heritage  is  likely  to  become  a  neurotic  adult. 
His  conception  of  the  universe  and  our  own  earth  and  the  life 
on  it,  including  himself,  is  on  too  grand  a  scale  to  permit  petty 
man-made  problems  to  shatter  his  nerves. 

Famous  People  As  Nature  Lovers 

It  is  true  that  some  children  show  a  deep  interest  in  flowers  and 
birds  and  beasts  without  any  special  encouragement  from  adults; 
but  if  they  can  share  their  interest  with  their  parents,  the  whole 
experience  becomes  more  vital  and  the  bonds  of  family  affection 
are  strengthened.  Many  leading  citizens,  who  are  not  only  famous 
but  have  also  been  successful  in  their  personal  lives,  have  happy 
childhood  memories  of  nature  exploring  with  their  parents. 

Theodore  Roosevelt's  closely  knit  family  had  a  wealth  of  such 
shared  interests,  and  when  he  was  President  of  the  United  States 
his  letters  to  his  children  away  at  school  were  filled  with  nature 
news.  When  spring  came  to  Washington,  he  reported  that  "not 
only  are  the  song  sparrows  and  robins  singing,  but  white-throated 
sparrows  which  will  soon  leave  us  for  the  North."  The  oncoming 
of  fall  was  noted  with:  "The  Virginia  creepers  and  some  maple 
and  gum  trees  are  scarlet  and  crimson.  The  oaks  are  deep,  red 
brown."  He  told  of  watching  a  mother  bird  bring  worms  to  her 
babies,  of  feeding  elk  at  the  zoo,  and  countless  other  incidents 
about  animals  and  plants. 

Mary  Mapes  Dodge,  who  won  world  fame  with  Hans  Brinker 


22  ]  What  Nature  Exploring  Can  Do  for  Your  Child 

and  the  Silver  Skates  and  other  writings,  fondly  recalled  her 
father  as  a  companion  on  nature  jaunts.  One  of  her  most  vivid 
recollections  in  adult  years  was  of  a  trip  with  him  to  the  Botanical 
Gardens  in  New  York  where  some  plant  experiments  were  ex- 
plained. The  next  day,  with  her  father's  interested  approval,  Mary 
started  "a  little  botanical  garden"  at  her  bedroom  window— a 
sweet  potato  in  a  hanging  vase,  and  seeds  planted  in  old  teacups 
filled  with  different  kinds  of  soil. 

Herbert  Hoover  was  an  outstanding  geologist  and  mining 
engineer  before  he  became  President  of  the  United  States.  He 
was  an  "outdoor  boy"  from  babyhood  on,  and  only  the  worst  sort 
of  weather  could  keep  him  in  the  house.  His  parents  took  him 
often  to  his  grandfather's  farm  where  he  could  herd  cattle,  plant 
corn,  and  tend  chickens.  Though  his  father  died  when  the  boy 
was  small,  his  mother  found  time  in  her  busy  life  for  picnics  and 
other  outdoor  excursions.  It  was  on  these  outings  that  Herbert 
started  collecting  rocks— the  introduction  to  his  absorbing  lifelong 
interest  in  geology.  By  the  time  he  was  seven  he  knew  how  to  fish, 
forecast  storms,  and  track  animals;  he  loved  learning  about  the 
ways  of  birds,  snakes,  and  all  other  small  creatures  of  the  woods. 

As  a  friend  of  the  Hoover  family  puts  it,  "Bert  read  his  fairy 
tales  in  stones,  the  everlasting  hills,  the  dawn  of  creation,  the 
fashioning  of  a  universe."  This  heritage  of  nature  appreciation 
has  been  passed  on  to  Herbert  Hoover's  sons  and  grandchildren. 

In  all  countries,  men  and  women  have  achieved  eminence  after 
evincing  an  early  and  continuing  interest  in  the  world  around 
them,  and  particularly  in  nature's  ways.  Their  awareness  of  nature 
has  brought  greater  contentment  and  happiness  into  their  own 
lives.  Indeed,  they  have  enriched  the  lives  of  all  of  us  with  those 
achievements  of  the  inquiring  mind  that  has  been  trained  by 
close  and  habitual  observation. 

Wh^  Nature  Is  Important  to  Your  Qiild 

Modem  schools  have  excellent  programs  of  nature  study;  but 
even  the  best  programs  cannot  take  the  place  of  family  participa- 
tion in  nature  interests.  On  the  other  hand,  any  child  whose  parents 


What  Nature  Exploring  Can  Do  for  Your  Child  [  23 

enjoy  nature  with  him  finds  this  of  real  help  with  his  school  work. 
He  will  readily  discuss  ideas  that  are  presented  to  him  at  school 
when  he  knows  his  father  and  mother  are  interested. 

Actually  it  is  not  always  simple  to  keep  up  with  the  rapid  strides 
made  by  children.  It  seemed  I  had  barely  stopped  smiling  over  my 
three-year-old's  comments,  such  as,  "I  know  bees  make  honey, 
but  I  don't  see  how  they  get  it  into  jars,"  when  he  was  coming 
home  from  the  first  grade  asking,  "What  is  the  difference  between 
rodents  and  other  kinds  of  animals?"  A  year  later  he  was  likely  to 
interrupt  lunch  with  such  posers  as:  "If  dinosaurs  were  so  big  and 
powerful,  why  did  they  all  die?"  Suddenly  we  had  arrived  at  ques- 
tions that  still  puzzle  many  a  scientist. 

The  important  place  that  nature  has  in  the  life  of  a  young  child 
has  been  sensitively  analyzed  by  Arnold  and  Beatrice  Chandler 
Gesell.  Here  is  what  these  eminent  experts  on  child  behavior  say: 

"There  is  nothing  new  under  the  sun,  but  to  childhood  all  is 
novelty.  The  most  commonplace  things  teem  with  novelty. 

"Children  are  in  a  stage  of  sense  experience  when  this  warm 
glow  of  contact  through  eye  and  ear  and  touch  may  be  trans- 
mitted into  the  life  of  spirit;  when  light,  shadow,  sound,  motion, 
and  touch  weave  a  tangle  of  lovely  associations  around  common- 
place experiences  and  build  up  a  deep  appreciation  of  life  and 
things.  Thus  the  truths  of  nature  become  unconsciously  associated 
with  emotional  response,  which  deepens  and  safeguards  them. 
The  child  learns  more  through  unconscious  absorption  than 
through  didactic  prescription,  and  in  nature  study  daily  contact 
with  the  beauty,  motive,  and  unceasing  effort  everywhere  shown 
by  plant  and  animal  gives  an  impulse  to  individual  character  and 
sets  standards  of  behavior. 

"The  child  who  stands  on  tiptoe  to  peep  cautiously  into  the 
new-found  bird's  nest,  who  feels  the  velvety  softness  of  growing 
things  beneath  his  feet  as  he  hunts  out  the  tiny  wild  flowers  in 
the  spring,  who  sows  his  own  garden  seed  and  waits  to  see  the  first 
young  green  push  its  way  through  the  dark,  moist  soil  is  building 
up  a  reverence  for  life,  a  sense  of  kinship  with  it,  which  will 
uphold  him  in  his  later  and  deeper  understanding  of  its  meaning." 


CHAPTER^  How  to  Understand 
the  Birds 


GST  CHILDREN,  as  soon  as  they  are  old 
enough  to  take  an  interest  in  their  sur- 
roundings, delight  in  birds.  A  bundle  of  feathers  with  bright 
eyes  and  a  perky  air  of  self-confidence  is  an  appealing  figure 
whether  trilling  on  a  summer  day  or  seeking  food  in  wintry  gales. 
As  the  child  matures,  he  looks  more  inquiringly  at  the  graceful 
songster  with  which  he  has  become  familiar,  and  one  day  may 
startle  you  with  the  question: 

"What  makes  a  bird  a  bird?" 

Taken  off  guard  you  might  answer:  "A  bird  has  feathers  and 
wings  and  is  able  to  fly." 

But  there  you  stop  in  confusion.  Some  birds,  such  as  the  ostrich 
and  penguin,  do  not  fly!  A  fuller  explanation  will  take  this  into 
account.  Birds  are  warm-blooded,  feathered,  egg-laying  animals 
that  have  backbone  and  wings,  although  the  wings  do  not  neces- 
sarily serve  as  flying  aids.  Naturally,  you  will  have  to  expand 
this  description  to  make  it  clear  to  a  child— but  it  will  fit  the  tiny, 
speedy  hummingbird,  the  earth-bound  ostrich,  the  majestic  eagle, 
the  comical  puffin.  It  will  fit  the  feathered  creatures  of  woodlands, 
prairies,  oceanic  islands,  high  mountain  slopes,  lakes,  deserts, 
jungles  and  barnyards.  It  will  stand  up  under  such  a  challenge  as 
I  had  from  a  three-year-old: 

"But,  Mommy,  you  called  the  chicken  a  bird.  It's  a  chickenF' 

24 


How  to  Understand  the  Birds  [  25 

By  strongly  emphasizing  feathers  I  finally  persuaded  her  that 
even  the  stalwart  barnyard  fowl  deserves  to  be  ranked  with  the 
birds.  Feathers  are  about  the  only  feature  which  birds  do  not 
share  with  any  other  kind  of  animal. 


Feathers  for  Clothes 

Bird  plumage  is  often  so  beautiful  that  we  are  likely  to  over- 
look its  practical  value.  What  clothes  are  to  people,  feathers  are 
to  birds:  undergarments,  overcoat  and  raincoat  all  in  one. 

Watch  a  chicken  caught  in  a  rainstorm  and  you  will  have  a 
perfect  illustration  of  the  "raincoat."  The  chicken  droops  its  wings 
and  tail,  making  the  best  possible  use  of  the  feathers— for  rain 
flows  off  them  as  it  does  from  your  slicker.  Examine  one  of  the 
feathers  and  you  will  find  it  has  three  distinctive  parts:  the  quill 
(or  central  stem) ;  the  barbs  attached  to  the  major  part  of  the 
quill;  and  a  soft  fluff.  This  fluff,  snuggling  against  the  body  at 
the  base  of  the  quill,  plays  the  part  of  warm  underclothing. 

Why  Protective  Coloring  Is  Important 

Feathers  often  serve  birds  as  camouflage.  We  quickly  recognize 
this  in  many  wild  birds.  The  value  of  protective  coloring  in 
chickens  is  less  obvious  to  us  because  we  usually  see  them  in  a 
barnyard.  Were  a  hen  living  in  a  state  of  nature,  wandering  in 
grassy  fields  with  her  chicks,  her  neutral  color  would  blend  with 
her  surroundings.  It  is  the  rooster  who  is  decorative,  having  lovely 
iridescent  tail  feathers  and,  sometimes,  colorful  neck  plumage. 

Wild  birds  offer  many  convincing  examples  of  the  safety  value 
of  camouflage.  The  female  Baltimore  oriole,  for  example,  is  a 
dull  orange-yellow  while  her  mate  is  a  brilliant  combination  of 
vivid  orange,  black,  and  white.  Among  the  cardinals,  the  male 
is  a  rich  red;  the  female's  plumage  is  light  brown  with  only  the 
faintest  tinge  of  red.  The  name  "rose-breasted  grosbeak"  is  appro- 
priate for  the  male  of  this  species,  as  he  displays  a  deep  rose  patch 
on  his  white  breast;  but  his  mottled  yellow-brown  and  white  mate 
looks  rather  like  an  overgrown  sparrow. 


26  ]  How  to  Understand  the  Birds 

In  each  case  we  see  the  same  principle  at  work:  The  mother 
birds  that  must  look  after  the  eggs  and  babies  do  not  attract 
notice.  Meanwhile  the  arrestingly  colored  males  can  remain  at  a 
suitable  distance  from  the  nest,  distracting  the  attention  of 
squirrels  or  other  possible  enemies. 

You  may  notice  an  interesting  phase  of  protective  coloration 
in  birds  that  are  "molting."  When  the  males  of  certain  species 
lose  their  bright  feathers  after  the  mating  season,  they  develop 
new  ones  of  somber  hues.  By  fall  the  male  scarlet  tanager  is  the 
same  dull  yellow  green  as  his  mate;  both  male  and  female  bobolink 
become  sparrow-like  in  appearance;  and  the  bright  yellow  body- 
feathers  of  the  goldfinch  have  given  way  to  others  of  dull  yellow 
brown.  So  garbed,  the  male  birds  are  fairly  inconspicuous  until 
the  time  comes  again  for  them  to  be  gaily  attractive  to  the  females. 

New  Feathers  for  Old 

If  late  summer  happens  to  be  the  time  that  your  boy  or  girl 
starts  to  show  a  more  than  casual  interest  in  birds,  the  subject 
of  molting  makes  the  most  dramatic  theme  to  explore.  Some 
species  lose  their  worn  and  faded  feathers  in  August,  and  by 
September  have  a  completely  new  plumage.  Among  the  excep- 
tions to  this  schedule  are  waterfowl,  which  begin  to  molt  in  June. 
By  September  they  have  passed  through  two  molts,  during  which 
they  took  on  and  discarded  a  dull  plumage. 

Unless  there  is  a  definite  change  in  a  bird's  coloration  during 
molting,  the  process  is  not  easy  to  observe,  since  the  change  is 
gradual.  Starting  with  one  certain  feather— usually  this  is  the  inner- 
most primary  wing  feather— it  continues  over  the  wings  until  all 
are  replaced.  The  feathers  of  some  kinds  of  birds  develop  all  over 
the  body  at  the  same  time,  while  on  others  the  development  comes 
in  patches.  Ducks,  grebes,  loons  and  other  swimming  birds  which 
do  not  depend  on  flight  as  their  only  means  of  locomotion,  molt 
all  feathers  at  the  ends  of  the  wings  (the  primaries)  within  a 
very  short  time. 

Feathers  do  not  grow  haphazardly  over  a  bird's  body,  but  are 
arranged  in  definite  lines  or  patches    (called  "feather  tracts") 


How  to  Understand  the  Birds  [  27 

between  which  there  are  bare  areas.  However,  the  overlapping 
of  feathers  of  the  adjacent  tracts  keeps  the  skin  completely  covered 
in  healthy  birds.  You  may  see  a  chicken  looking  "half-naked"  as 
the  result  of  arrested  feather  development.  This  never  happens 
to  wild  birds  unless  they  are  diseased. 

Most  birds  molt  only  once  a  year,  but  the  brilliantly  colored 
males  that  have  dull  winter  coats  must  change  again  to  regain 
their  beauty  in  the  spring.  Hence  such  birds  as  the  scarlet  tanager 
and  the  goldfinch  undergo  a  spring  (prenuptial)  as  well  as  fall 
(postnuptial)  molt.  The  spring  molt  is  usually  not  complete,  how' 
ever;  the  wing  and  tail  feathers  serve  both  plumages. 

Some  birds  change  appearance  between  winter  and  spring 
without  undergoing  a  second  molt.  They  do  so  merely  by  "feather 
wear";  that  is,  the  feather  tips  which  have  given  the  general  tone 
to  the  winter  plumage  wear  away  and  expose  the  bright  colors  of 
the  breeding  plumage.  The  robin  is  a  notable  example.  His  breast 
becomes  redder  as  spring  advances  because  the  gray  feather  tips 
are  wearing  off.  In  other  birds  yellow,  brown,  and  gray  most 
frequently  edge  the  feathers  in  winter  plumage.  As  these  colors 
disappear,  black,  brown,  or  red  is  revealed. 

Molting  consumes  energy.  While  it  is  growing  a  new  set  of 
feathers,  a  bird  neither  sings  nor  fights,  staying  in  seclusion  except 
when  it  must  seek  food.  It  is  for  this  reason,  rather  than  because 
of  an  early  departure  for  southern  climes,  that  you  see  few  birds 
in  late  August  and  early  September.  As  soon  as  the  birds  have 
completed  their  molting  they  regain  their  vitality  and  are  ready 
to  migrate  or  to  face  the  rigors  of  a  northern  winter. 

The  Versatile  Beak 

The  child  who  is  always  asking  "Why?"  will  be  fascinated  by 
the  endless  variety  of  bird  beaks.  In  almost  every  case,  beak 
formation  gives  us  the  clue  to  a  bird's  eating  habits,  diet— and 
even  its  surroundings.  The  duck,  for  example,  has  a  wide,  flat 
bill  that  equips  it  for  feeding  on  water  insects  and  plants.  After 
seizing  food  in  its  beak,  the  duck  holds  the  food  until  the  water 
strains  out  of  the  sievelike  edges.  Given  the  same  conditions,  the 
sharp,  horny  beak  of  the  hen  woula  be  quite  useless.  The  hen's 


28  ]  How  to  Understand  the  Birds 

beak  resembles  a  pick  rather  than  a  scoop,  and  it  strikes  efficiently 
into  the  soil  for  insects  or  seeds. 

Another  bird  with  a  sharp,  seed-eating  beak  is  the  sparrow.  As 
for  the  woodpecker,  its  beak  is  virtually  a  chisel.  You  may  spy 
one  of  these  birds  drilling  for  insects,  or  come  upon  the  evidence 
where  a  woodpecker  has  left  a  series  of  holes  in  a  tree  trunk. 

These  are  but  a  few  examples  of  the  close  relationship  between 
the  style  of  a  bird's  beak  and  the  kind  of  food  that  it  eats.  Children 
will  get  the  point  at  once  if  you  tell  them  the  delightful  Aesop 
fable  of  the  stork  and  the  fox.  The  stork,  having  been  served  soup 
in  a  shallow  dish  by  his  host,  a  fox,  gets  his  revenge  by  inviting 
the  fox  to  dinner  and  serving  it  in  a  narrow-necked  vessel  down 
which  its  own  long  bill  fits  perfectly. 

Getting  food  for  the  adult  and  feeding  the  young  are  the 
two  basic  uses  of  the  beak.  But  it  has  other  important  functions: 
It  is  a  tool  for  gathering  nesting  material  and  digging  nesting  sites 
and  it  often  serves  as  a  weapon  of  attack  or  defense.  It  also  enables 
many  birds  to  do  an  effective  job  of  preening  and  smoothing  their 
plumage  and  keeping  it  clean. 

If  the  hen  you  watched  during  a  storm  could  be  observed  after 
the  rain  stopped,  you  might  see  her  using  her  beak  to  oil  her 
feathers.  There  is  an  oil  gland  on  her  back,  just  at  the  base  of 
the  tail  feathers.  She  presses  the  gland  with  her  beak  to  force  out 
oil;  then  she  rubs  the  beak  over  the  surface  of  her  feathers  and 
passes  it  through  them.  Now  her  "oilskin  slicker"  is  ready  for  the 
next  downpour.  A  number  of  other  birds,  including  waterfowl, 
use  this  same  oiling  method. 

The  parrot's  curved  bill  is  unique  in  construction  and  use,  as 
it  is  a  first-class  climbing  aid.  The  upper  mandible,  or  beak,  is 
movable,  being  connected  to  the  bird's  skull  by  a  hinge.  When 
the  parrot  climbs,  it  uses  this  mandible  as  a  hook  to  support  its 
body  while  its  feet  find  a  new  resting  place. 

Feet  Are  Versatile  Too 

Versatile  as  the  beak  is,  the  bird's  feet  are  equally  valuable 
tools.  Wading  birds,  such  as  flamingoes  and  herons,  have  extremely

THE  FLAMINGO-LONG  AND  LUGUBRIOUS 

''Long''  is  the  key  word  for  the  flamingo:  long  body,  long  bill,  long  neck,  long 
legs,  long  toes.  Its  weird  habits  include:  sleeping  in  its  famous  one-legged  stance, 
eating  with  its  head  upside-down,  and  roosting  on  its  foot-high  cone-shaped  nest. 

long  toes  which  distribute  their  weight  and  keep  them  from  sink- 
ing into  soft  mud.  Short-tailed  birds— the  murres,  for  example- 
use  the  feet  as  rudders  during  flight.  Diving  birds,  such  as  grebes, 
use  their  feet  to  propel  them  under  water. 

Whenever  you  see  a  bird  scratching  for  food,  you  are  noticing 
another  use  for  its  feet.  Birds  of  prey,  such  as  eagles  and  hawks, 
seize  their  victims  in  their  long,  powerful  talons.  Many  birds  use 
their  feet  to  gather  and  place  nesting  material;  with  other  birds, 
the  feet  are  fighting  weapons.  The  parrot  uses  a  foot  to  grasp  and 
bring  food  to  its  mouth,  much  as  we  use  a  hand.  So  we  see  that  a 
bird's  feet  serve  many  purposes  aside  from  the  most  obvious  one 
of  supporting  its  body. 


Sharp  Eyes  and  Ears 

Are  the  bright  eyes  of  a  bird  as  efficient  as  their  alert  and 
shining  appearance  leads  you  to  believe?  They  really  are:  Birds 
are  much  more  sharp-sighted   than  we  are.  Not  only  do  birds 


30  ]  How  to  Understand  the  Birds 

have  keen  vision,  but  some  of  them  are  remarkably  well  adapted 
for  seeing  objects  both  far  away  and  at  close  range.  Thus  a  hawk 
flying  so  high  that  it  would  appear  as  a  mere  speck  to  us,  may 
look  down  and  see  a  rabbit  or  even  a  mouse  on  the  ground!  The 
hawk  has  two  centers  of  vision,  and  as  it  swoops  down  from  the 
heights,  its  vision  shifts  from  one  center  to  the  other  so  that  its 
eyes  are  adjusted  for  short-range  work  when  it  seizes  its  prey. 

Yet  most  birds,  despite  their  sharp  eyes,  do  not  have  bifocal 
vision  like  the  hawk.  One  consequence  is  that  they  do  not  detect 
telephone  and  telegraph  wires,  and  many  birds  are  injured  or 
killed  every  year  by  collision  with  such  obstacles. 

Among  birds  there  is  quite  a  bit  of  variety  in  the  color  of  the 
iris;  it  may  be  brown,  gray,  blue,  yellow,  white,  pink,  purple, 
green,  and  even  red.  The  red-eyed  vireo  takes  the  first  part  of 
its  name  from  this  striking  feature.  The  hen,  which  is  ideal  for 
bird  study,  has  a  yellow  iris.  It  is  equipped  with  an  eyelid  that 
shuts  out  vision,  coming  up  from  the  bottom  of  the  eye,  however, 
rather  than  down  from  the  top.  It  also  has  another  kind  of  eyelid 
—a  film  that  moves  across  the  eye  from  the  inside  corner  to  the 
outer  side. 

You  may  escape  questioning  about  a  bird's  hearing  ability 
because  their  ears  are  fairly  well  hidden.  Then  suddenly  this 
very  fact  may  be  the  basis  for  a  query  from  your  young  observer: 

"How  can  that  bird  hear?  I  don't  see  any  ears!" 

Except  for  the  owls,  which  have  noticeable  "ear  tufts,"  the 
ear  of  a  bird  is  no  more  than  a  hole,  rather  well  covered  with 
feathers,  on  the  side  of  its  head.  Yet  a  bird's  hearing  is  just  as 
remarkable  as  its  sight— perhaps  even  more  remarkable.  Walking 
in  a  field  or  forest  you  may  notice  how  the  snapping  of  a  small 
twig  will  startle  and  put  to  flight  a  bird  that  is  a  considerable 
distance  away.  And  when  you  see  a  robin  cocking  its  head  and 
realize  it  is  listening  for  an  earthworm  under  the  surface  of  the 
ground,  you  develop  a  well-deserved  respect  for  birds*  hearing. 

How  Birds  Fly 

"How  do  birds  fly?"  is  a  question  that  most  children  ask  at 
some  time.  The  child  may  accompany  his  query  with  a  leap  into 


How  to  Understand  the  Birds  [  ^i 

the  air,  arms  outstretched,  and  a  faint  hope  that  he  too  can  "take 
oflE." 


Birds  are  Built  for  FucHt 

It  helps  your  inquisitive  child  to  understand  the  mechanics 
of  flight  if  you  point  out  that  the  bird's  streamlined  form  is  of 
great  advantage  in  flying.  Besides  this,  it  has  an  extremely  light 
structure:  Its  bones  and  the  shafts  of  its  feathers  are  hollow  and, 
as  is  easily  seen,  the  size  of  its  wing  is  greater  in  proportion  to 
its  body  than  an  arm  is  to  the  human  body. 

You  can  then  go  on  to  compare  the  child's  framework  to  the 
bone  and  feather  structure  of  the  bird,  which  has  a  bone  corres- 
ponding to  his  upper  arm  and  another  to  the  bone  between  his 
elbow  and  wrist.  Have  the  child  extend  his  thumb  upward,  hold 
his  first  and  second  fingers  in  a  horizontal  position,  and  fold  the 
other  two  into  his  palm— somewhat  as  he  would  do  in  making  a 
pretend-gun  out  of  his  hand.  This  will  give  him  a  rough  com- 
parison with  the  structure  of  a  bird's  wing. 

The  bird  has  a  winglet  corresponding  to  the  child's  thumb, 
and  a  second  and  third  digit  similar  to  his  extended  fingers. 
These  are  sometimes  extended  upright,  but  may  also  be  held 
horizontally.  While  the  child's  arm,  hand,  and  fingers  are  covered 
only  with  skin,  the  bird  has  flight  feathers  also— one  sheath  on 
the  "forearm,"  and  another  series  on  the  "hand."  The  number 
of  feathers  varies  in  different  birds. 

FuGHT  Techniques 

There  are  four  types  of  bird  flight:  flapping,  gliding,  static 
soaring,  and  dynamic  soaring.  In  flapping  flight  the  "arm"  wings 
help  to  lift  most  large  wings  into  the  air,  while  the  "hand"  wings 
produce  propulsion  through  the  air.  Speed  or  forward  motion  is 
gained  with  each  downward  stroke  of  the  wings;  lift  is  obtained 
on  up-and-down  strokes.  In  this  up-and-down  motion  the  wing 
tips  move  through  a  much  greater  arc  than  the  wrists  would. 
(In  airplane  flight  lift  and  speed  are  produced  by  the  propeller 
and  the  wings.)  In  small  birds,  such  as  the  finch,  the  whole  wing 


32  ]  How  to  Understand  the  Bird^ 

flaps  as  a  unit,  producing  speed  and  lift  at  the  same  time.  During 
the  upstroke,  the  wing  is  folded. 

When  a  bird  glides,  it  loses  altitude  to  keep  its  forward-pushing 
motion.  In  static  soaring,  the  bird  takes  advantage  of  up-air  cur- 
rents which  offset  the  loss  of  altitude  suffered  during  its  gliding 
flight.  For  dynamic  soaring  a  bird  such  as  the  albatross  will  use 
the  force  of  the  wind.  Wind  force  increases  with  altitude;  hence 
the  bird,  after  descending  most  of  the  way,  levels  off  with  the 
slowing  down  of  the  wind  near  the  surface  of  the  water,  and  then 
ascends  again,  once  more  making  use  of  the  air  currents. 

Birds  use  their  wings  differently  depending  on  the  kind  of 
flight,  such  as  horizontal,  soaring,  descending,  gliding,  hovering, 
taking  off,  and  climbing.  Various  types  of  birds  have  wings  of 
different  shapes  and  proportions,  and  each  employs  each  wing  in 
the  distinctive  manner  appropriate  to  it. 

An  important  feature  of  the  bird's  flying  mechanism  is  a  sinew 
with  elastic  qualities.  On  the  downward  thrust  of  the  wing,  the 
sinew  holds  the  feathers  in  a  tight  overlapping  position.  When 
the  wing  comes  up,  the  tension  of  the  sinew  relaxes  and  t^ 
feathers  part  and  rotate.  This  allows  air  to  flow  between  then^ 
as  an  aid  in  flight. 

It  gives  us  pleasure  to  understand  how  birds  fly,  but  all  the 
analysis  in  the  world  cannot  dim  the  initial  thrill  of  seeing  birds 
in  flight. 

The  Mystery  of  Migration 

There  is  no  more  fascinating  way  of  arousing  interest  in  flight 
than  having  your  child  catch  a  sight  of  migrating  birds— perhaps 
a  flight  of  geese  in  military  formation,  or  a  close-massed  flock  of 
grackles  racing  like  a  dark  wind-blown  cloud.  Even  after  years  of 
research  and  experiment,  scientists  speak  of  the  "mystery"  of  bird 
migration,  for  they  still  do  not  completely  understand  it.  Yet, 
puzzling  as  this  semiannual  pilgrimage  of  countless  birds  is,  it  is 
no  more  puzzling  to  me  than  the  way  in  which  my  daughter  took 
note  of  it  before  she  reached  her  second  birthday.  On  three  differ- 
ent occasions  we  were  having  a  late  afternoon  walk  along  streets 


How  to  Understand  the  Birds  [  33 

brightening  with  rows  of  electric  lights  and  alive  with  home- 
bound  traffic,  when  the  little  girl  in  the  stroller  looked  up  and 
pointed  in  great  excitement: 

"Look,  birdies!" 

And  there  they  were— large  flocks  of  them,  high  above  the  city's 
hubbub,  traveling  in  steady  and  sure  flight  toward  their  winter 
destination.  The  wonderful  instinct  that  keeps  birds  on  their 
course  in  long-distance  travel  has  been  called  a  "sixth  sense,"  and 
it  seemed  that  a  similar  sense  must  have  prompted  this  mite -to 
take  her  eyes  from  the  noise  and  excitement  on  the  ground  at 
exactly  the  right  time  to  catch  the  nature  news  high  in  the  sky. 
Now  that  she  is  older  we  have  fun  deliberately  watching  for  the 
"birdies." 

Not  all  birds  migrate.  Some  you  will  know  as  "permanent 
residents"  in  your  neighborhood.  The  migratory  birds  that  arrive 
in  the  spring  and  remain  through  the  summer  are  "summer  resi- 
dents." Fall  migrants  that  remain  through  the  cold  season  are 
"winter  residents."  Other  birds  you  may  see  only  briefly  as  they 
pass  through  to  nesting  grounds  or  winter  quarters.  These  you 
know  as  "transients."  Migratory  birds  thus  are  different  things 
to  different  people,  for  your  summer  residents  are  winter  residents 
in  other  regions  and  your  transients  somewhere  become  winter 
and  summer  residents. 

A  confusing  fact  about  migration  is  that  certain  well-known 
migrators  do  not  travel  as  far  south,  or  north,  as  we  think.  Accord- 
ing to  popular  belief,  the  robin,  that  noted  herald  of  spring, 
winters  in  the  warm  comfort  of  the  South.  It  is  a  bit  disconcerting 
therefore,  when  taking  a  winter  walk,  to  see  a  robin  hunting 
food  amid  frozen  surroundings,  especially  if  the  boy  or  girl  with 
you  asks: 

"Don't  robins  go  south  in  winter?" 

The  majority  of  them  are  reveling  in  southern  sunshine.  Many 
are  along  the  Gulf  coast,  some  are  in  Mexico,  and  enormous  flocks 
are  in  Florida,  feeding  on  holly  and  mistletoe  berries.  But  a  few 
elect  to  remain  in  northern  climes  with  only  the  friendly  ever- 
greens to  shield  them.  You  may  also  see  occasional  members  of 
other  species,  such  as  the  bluebird,  song  sparrow,  meadow  lark, 


34  ]  How  to  Understand  the  Birds 

redwinged  blackbird,  and  cedar  waxwing,  braving  the  northern 
winter. 

Sky  Lanes  of  the  Birds 

Because  the  expressions  "traveling  north"  or  "flying  south" 
are  used  repeatedly,  children  are  apt  to  believe  that  the  birds 
migrate  unfailingly  in  these  directions.  However,  this  is  not  an 
accurate  picture,  as  some  fly  southeast,  others  southwest.  Certain 
species  have  followed  fixed  travel  routes  until  they  have  become 
well-defined  pathways,  or  sky  lanes,  for  these  birds.  Some  travel 
north  by  one  route  and  return  south  by  another,  perhaps  leading 
over  an  entirely  different  part  of  the  country.  Or  else  one  route 
may  be  over  land  and  the  return  route  over  water.  The  golden 
plover  is  an  interesting  example  of  these  birds  that  have  a  "double 
migration  route."  In  the  spring  it  travels  from  South  America  to 
Labrador  in  as  direct  a  line  as  possible,  through  the  middle  of 
the  North  American  continent.  In  the  fall  it  goes  eastward  to  the 
Atlantic,  and  much  of  its  return  flight  is  over  water.  On  this 
longer  course  it  must  fly  2,400  miles. 

Flying  Hours 

There  are  also  variations  in  the  time  of  day  for  migratory 
flight.  Some  birds  are  on  the  wing  by  day,  others  by  night,  while 
still  others  are  active  day  and  night.  Warblers,  thrushes,  and  wood- 
cocks are  among  the  night  fliers;  geese,  crows,  swallows,  robins, 
hummingbirds,  blue  jays,  and  bluebirds  are  a  few  of  the  daytime 
travelers.  As  for  ducks,  you  may  see  them  on  the  wing  day  or  night. 

How  Fast  Do  Birds  Fly? 

Long  ago,  birds  were  credited  with  a  speed  that  approaches 
the  speed  of  a  modern  airplane.  The  theory  was  that  most  birds 
performed  the  greater  part  of  their  journey  in  one  night!  In 
recent  times  the  speed  of  many  birds  has  been  "clocked"  accurately 
with  the  aid  of  airplanes  and  motorcars.  We  now  know  that  a 
hundred  miles  an  hour  is  an  exceptionally  fast  rate,  achieved  by 
only  a  few  birds,  such  as  certain  swifts. 

In  making  their  migratory  flights  most  birds  apparently  move 


How  to  Understand  the  Birds 


[35 


at  a  rate  somewhere  between  twenty  and  fifty  miles  an  hour.  The 
great  journeys  made  by  some  species  are  accomplished  by  the 
birds  moving  for  long  hours  at  a  steady  rate  rather  than  by  great 
bursts  of  speed  over  short  distances.  When  we  compare  the  speed 
of  an  individual  bird  with  the  time  it  takes  a  flock  of  that  same 
species  to  complete  its  migratory  journey,  we  realize  that  the 
birds  do  not  fly  continuously  night  after  night  or  day  after  day. 
They  may  pause  for  extended  rests  or  for  favorable  weather 
conditions. 

Where  Birds  Migrate 

In  the  autumn  several  familiar  species  of  smaller  birds  go 
as  far  as  Central  and  South  America.  Bobolinks,  for  instance, 
leave  the  fields  and  meadows  of  northern  states  traveling  south- 
ward in  leisurely  fashion  through  the  West  Indies  and  along 


T><E  BOBOLINK-MIGRATOR  EXTRAORDINARY 

Every  winter  the  bobolink  journeys  some  five  thousand  miles  from  its  United  States 
haunts  to  Brazil  or  Argentina,  v^here  it  relishes  their  summer  weather  in  the  winter 
months.  The  bobolink  is  vrelcomed  where  it  devours  weed  seeds,  detested  where 
it  destroys  rice  croj>s.

eastern  Central  America.  Even  when  they  reach  the  northern 
parts  of  South  America  they  are  not  satisfied  but  continue  until 
they  come  to  the  wide  open  plains  and  marshes  of  southern  Brazil 
and  northern  Argentine. 

In  contrast  to  these  we  have  some  birds  that  migrate  for  only 
short  distances.  The  chickadee  is  one;  the  crow  is  another.  Such 
birds  may  move  southward  from  your  community  in  the  fall,  only 
to  be  replaced  by  other  chickadees  or  crows  moving  down  from 
points  farther  north.  Thus  while  you  seem  to  have  the  same  birds 
the  year  round,  they  are  actually  different  individuals. 

We  can  sum  up  some  of  the  puzzling  aspects  of  bird  migration 
by  saying  that  in  its  simplest  form,  migration  is  merely  a  journey 
away  from,  and  back  to,  a  nesting  ground,  and  apparently  made 
without  any  relation  to  temperature. 

How  TO  Keep  a  Bird  Calendar 

If  you  live  in  a  region  where  the  four  seasons  are  clearly 
defined  by  sharp  weather  contrasts,  the  study  of  bird  migrations 
will  provide  you  with  an  especially  enjoyable  hobby.  By  keeping 
a  bird  calendar  you  can  note  the  comings,  the  goings,  and  the 
passings  through  of  different  species.  Your  calendar  can  be  quite 
simple:  a  large  ruled  sheet  of  paper,  divided  into  four  columns. 
Head  the  first  column  "Date,"  the  second  "Bird's  Name,"  the 
third  "Where  Seen,"  the  fourth  "Time  of  Day."  You  may  simply 
fill  in  information  about  birds  that  come  near  your  home,  but 
the  record  becomes  far  more  lively  when  you  widen  the  range  of 
observation  by  means  of  bird  walks. 

Some  children  enjoy  such  a  project  as  an  individual  enterprise. 
Others  are  more  stimulated  if  the  calendar  is  a  family  affair  with 
scope  for  friendly  rivalry.  Who  will  have  the  fun  of  recording 
the  first  robin  of  spring?  Who  will  see  a  bluebird  this  year?  Who 
will  trace  a  song  sparrow  by  its  lilting  melody  or  look  for  a  hum- 
mingbird near  its  nest?  Interest  becomes  keener  when  you  keep 
calendars  year  after  year,  trying  to  better  the  record  of  observation 
with  each  new  calendar.

How  to  Be  a  Good  Neighbor  to  the  Birds 

There  are  a  number  of  ways  to  bring  wild  birds  close  to  yout 
home  where  you  may  enjoy  them  and  study  them.  One  of  the 
most  effective  overtures  of  friendship  is  to  provide  a  birdbath. 
Songbirds  as  a  rule  seem  to  be  attracted  by  water.  Some  of  them 
even  relish  taking  a  bath  when  it  is  raining;  but  during  hot  dry 
spells  when  many  natural  sources  of  water  dry  up,  your  birdbath 
will  serve  a  really  essential  purpose. 

There  are  also  times  when  birds  have  trouble  finding  drinking 
water.  The  simplest  way  to  provide  a  bath  and  drinking  fountain 
is  to  set  a  shallow  pan  filled  with  water  on  the  ground,  on  a  post, 
or  on  a  ledge.  In  placing  the  pan,  keep  in  mind  the  danger  from 
cats.  These  enemies  must  not  have  any  nearby  hiding  place  from 
which  to  launch  a  surprise  attack  against  the  birds.  A  birdbath 
of  concrete  comes  near  to  being  ideal  because  its  dull  surface 
blends  well  with  the  browns,  greens,  and  grays  that  surround  it, 
and  its  rough  surface  makes  perching  easy. 

Feeding  the  Birds  in  Wintertime 

You  can  also  attract  birds  by  building  houses  and  shelters 
for  them.  But  probably  the  greatest  service  you  can  render  is  to 
furnish  winter  food.  Though  completely  self-reliant  in  warm 
weather,  the  birds  that  remain  north  throughout  the  year  are 
often  desperate  for  food  during  the  winter  months.  Birds  have 
an  exceptionally  high  body  temperature,  and  so  long  as  they  have 
sufficient  food  to  keep  this  temperature  normal  they  do  not  suffer 
from  the  cold.  But  if  a  scarcity  of  food  results  in  a  lowering  of 
the  body  temperature,  the  birds  suffer  severely  and  may  even 
freeze  to  death. 

You  can  provide  food  for  them  in  a  number  of  ways.  If  you 
have  a  yard,  simply  trample  down  the  snow  at  some  suitable  spot 
and  sprinkle  crumbs  and  seeds.  Or  else  you  may  tie  pieces  of  suet 
to  trees  or  posts.  A  feeding  tray  fastened  to  a  window  makes  a 
good,  safe  feeding  station  and  also  gives  you  a  wonderful  oppor^ 
tunity  to  watch  birds  at  close  quarters.  You  can  even  photograph 
them  without  much  trouble.  Cut  a  circular  hole  at  the  bottom  of 


58] 


How  to  Understand  the  Birds 


a  board  that  fits  into  the  window  frame  where  your  feeding  tray 
is  placed.  When  you  wish  to  take  pictures  you  can  raise  the  window, 
insert  the  board  barrier,  and  direct  your  camera  through  the  hole. 
Birds  will  partake  of  your  food  offering  without  the  least  alarm 
as  they  let  themselves  be  photographed. 

Feeding  trays,  moreover,  have  their  uses  beyond  country  or 
suburb.  A  businessman  in  Topeka,  Kansas,  who  decided  to  put 
a  tray  of  sunflower  seeds  at  his  office  window  sill,  reported  that 
the  following  day  it  was  visited  by  a  chickadee,  a  downy  wood* 
pecker,  a  junco,  and  a  brown  creeper. 

One  other  excellent  type  of  feeding  station  is  a  covered  plat- 
form attached  to  a  post.  The  covering  keeps  the  food  dry  and  the 
elevation  protects  the  birds  while  they  are  eating.  There  are  many 
other  efficient  types  of  bird  feeders  that  you  can  buy  or  make  and 
place  on  porch,  window  sill,  or  around  the  yard. 

What  Birds  Feed  On 

Insect-eating  birds,  such  as  chickadees  and  woodpeckers, 
welcome  suet  when  their  usual  food  is  not  available.  Seed-eating 
birds  are  not  greatly  tempted  by  fat,  but  they  thrive  on  stale

THE  GROUSE-SPORTSMAN'S  FAVORITE 

These  handsome  game  birds  are  great  favorites  with  hunters.  Grouse  are  hardy 
creatures,  accustomed  to  living  through  the  rigors  of  severe  v/inter.  When 
their    usual    insect    diet    is    not    available,    they    get    by    on    twigs    and    buds. 


How  to  Understand  the  Birds  i  jg 

bread,  crackers  and  cake  broken  into  crumbs,  sunflower  seeds, 
squash,  and  cracked  corn.  Nuts  are  a  special  treat  to  many  birds, 
and  a  number  of  them  are  fond  of  peanut  butter.  It  is  worth  while 
to  remember  the  ground  birds,  such  as  pheasant,  grouse,  and  quail, 
if  they  live  near  you.  A  spot  by  a  hedge  or  a  clump  of  trees  makes 
a  good  feeding  place  for  them.  During  a  winter  of  extreme  snow 
and  sleet,  you  may  help  them  to  survive  by  supplying  corn  or  other 
grains  in  a  simple  lean-to  shelter. 

Birds  as  Songsters 

Spring  is  the  time  to  enjoy  the  singing  of  birds,  for  it  is  during 
the  nesting  season  that  their  choral  symphony  is  in  full  swing. 
Most  of  the  singing  is  instinctive  and  probably  an  attempt  on  the 
part  of  the  male  to  intimidate  other  males.  What  makes  this  seem 
likely  is  that  the  males  of  some  species  reach  their  nesting  grounds 
well  ahead  of  their  female  audience.  "Singing  for  fun"  is  charac- 
teristic of  certain  caged  birds  whose  only  companionship  is  that 
of  human  beings.  Then  there  are  species  that  have  a  second  sing- 
ing period  after  the  postbreeding  molt;  but  this  lasts  only  a  few 
days. 

A  frequent  question  I  have  received  in  letters  from  children  is: 
"Do  birds  sing  when  they  are  flying?"  Unfortunately  it  is  not  pos- 
sible to  give  the  eager  correspondents  a  simple  yes-or-no  answer. 
As  a  rule,  singing  usually  takes  a  bird's  undivided  attention,  but 
some  birds— the  bobolink,  for  one— do  sing  while  flying  as  well  as 
when  perching.  Other  birds,  besides  singing  from  a  perch,  indulge 
in  occasional  songs  of  "ecstasy"  as  they  bound  into  the  air  and 
seem  about  to  burst  with  their  hurried,  twittering  notes.  The 
meadow  lark  and  goldfinch  are  just  two  of  the  species  which  carry 
on  in  this  delightful  fashion. 

Other  Bird  Sounds 

Aside  from  its  song  a  bird  can  produce  several  other  kinds 
of  sounds.  Some  of  these  are  very  useful  in  the  baby  stage,  as  when 
the  young  greet  their  parents  from  the  nest  with  what  is  unmis' 
takably  a  hunger  call.  Some  babies  can  follow  the  parent  around

How  to  Understand  the  Birds 


THE  GOLDFINCH-ECSTATIC  SONGSTER 

Like  their  famous  relatives  the  canaries,  goldfinches  are  inspired  singers.  They 
sing  while  perching  and  sometimes  bound  into  the  air  with  an  ecstatic  outburst  of 
twittering  notes.  The  goldfinch  flies  in  graceful  curves  that  are  a  pleasure  to  watch. 


shortly  after  hatching;  the  youngsters  of  these  species  make  a 
peeping  sound  which  prevents  them  from  getting  lost.  As  the  bird 
matures,  it  develops  a  "vocabulary"  of  some  variety.  It  has  a  call, 
especially  useful  during  migration,  which  keeps  it  in  touch  with 
the  rest  of  the  group.  It  can  also  give  a  call  of  alarm  and  one  of 
warning. 

While  some  birds  have  won  a  reputation  as  excellent  songsters, 
others,  such  as  the  brown  pelican,  are  noted  for  being  virtually 
silent.  Then  there  are  birds  that  make  sounds  which  take  the  place 
of  song.  An  example  is  the  rufiEed  grouse  with  his  drumming. 


How  to  Understand  the  Birds  [  41 

The  male  grouse  produces  his  music  by  standing  stiffly  erect  with 
his  tail  down  and  fanning  the  air  with  his  wings.  He  may  select 
a  given  location,  say  a  log,  for  his  performance,  going  to  the  same 
spot  and  facing  in  the  same  direction  every  time  he  drums.  This 
habit  reminds  us  of  some  songbirds  that  become  greatly  attached 
to  favorite  perches  from  which  they  sing. 

When  you  hear  your  child  trilling  happily  at  his  play,  you  may 
tell  yourself  with  some  satisfaction  that  he  is  "singing  like  a  bird." 
Strictly  speaking,  however,  such  a  feat  is  impossible!  The  human 
voice  is  produced  in  the  larynx.  A  bird's  voice  comes  from  a  dif- 
ferent structure  called  the  syrinx,  located  at  the  base  of  the  wind- 
pipe. (In  Greek  mythology,  Syrinx  was  a  nymph  who  was  trans- 
formed into  a  tuft  of  reeds  from  which  the  god  Pan  made  his 
pipes.) 

Identifying  Birds  by  Their  Song 

"What  bird  is  that?"  is  a  frequent  question  from  youngsters 
who  are  becoming  interested  in  identification. 

If  you  are  able  to  recognize  the  songs  of  the  birds,  you  are  well 
on  the  way  to  the  right  answer.  Some  songs  are  as  characteristic  as 
the  bird's  physical  appearance:  The  interested  observer  and  lis^ 
tener  soon  recognizes  such  tunes  as  the  conk-a-ree-e  of  the  red- 
winged  blackbird  and  the  rollicking  medley  of  the  bobolink.  The 
best  time  of  the  year  to  begin  your  study  of  bird  songs  is  very  early 
in  spring,  before  migrants  arriving  in  large  numbers  create  a  con- 
fusion of  voices.  The  best  time  of  day  to  listen  is  the  morning  or 
late  afternoon.  Concentrate  at  first  on  the  songs  of  the  more  com- 
mon, hence  more  familiar,  birds  of  your  region.  This  will  make  it 
easier  for  you  to  distinguish  individual  calls  and  melodies  in  the 
chorus  that  arises  later  on  when  the  season  is  at  its  height. 

Certain  birds  make  recognition  quite  simple  for  you  by  calling 
their  own  names— for  it  was  their  calls  that  gave  them  their  names 
to  begin  with!  Among  the  better  known  of  these  are  the  bobolink, 
chickadee,  phoebe,  bobwhite,  and  whippoorwill. 
How  TO  Record  Bird  Songs 

While  you  may  not  be  able  to  write  out  bird  songs  in  musi- 
cal notation,  you  should  find  it  easy  to  jot  down  many  songs  in 


42  ]  How  to  Understand  the  Birds 

words  or  syllables.  This  is  instructive— and  amusing  too,  for  natur- 
ally any  two  listeners  may  arrive  at  varying  interpretations  of  the 
same  song.  Here  are  three  versions,  for  example,  of  the  song  of  the 
white-throated  sparrow:  Old  Sam  Peabody,  Peahody,  Peahody;  or, 
Sow  wheat  Peverly,  Peverly,  Peverly;  or.  Sweet  Canada,  Canada, 
Canada, 

Some  interpretations  have  been  published  so  often,  however, 
that  we  may  now  consider  them  as  standard.  Thus  the  scarlet 
tanager  is  supposed  to  say  chip-churr  and  the  nuthatch  ank,  ank. 
Though  the  robin  has  a  variety  of  sweet  songs,  its  apt  early  morn- 
ing serenade  is  wake-up,  cheer-up,  cheerily-up,  wake-up.  A  cardi- 
nal may  join  in  with  a  shrill  whoit,  whoit,  whoit,  whit,  whit,  whit, 
whit.  As  for  the  song  sparrow,  it  suggests  in  a  lyrical  mood:  maids, 
maids,  put  on  your  teakettle— ettle ,  ettle,  ettle.  Some  songs  are 
longer  and  have  more  variations;  we  write  their  lyrics  in  couplets. 
The  interpretation  of  the  brown  thrasher's  song  is  a  good  example: 

Shuck  it.  Shuck  it;  sow  it,  sow  it; 
Plow  it.  Plow  it;  hoe  it,  hoe  it! 

On  occasion  birds  may  vary  their  phrasing  just  enough  to  con- 
fuse us.  However,  an  excellent  way  to  become  familiar  with  bird 
songs  is  through  recordings.  In  many  stores— and  libraries  as  well 
—you  can  find  such  collections  as  "Bird  Songs"  and  "More  Bird 
Songs,"  both  recorded  by  Albert  R.  Brand. 

To  become  a  skillful  imitator  of  songs  and  calls  requires  a  great 
deal  of  practice.  The  chickadee  is  a  good  bird  to  imitate,  as  it  is 
a  particularly  responsive  bird.  If  you  can  get  the  chickadee  to 
answer  your  imitation  of  its  call,  you  will  be  sure  of  a  fascinated 
and  admiring  audience  in  your  child. 

How  to  Make  Birds  Feel  at  Home 

One  of  the  most  satisfying  outlets  for  the  energies  of  a  young 
carpenter  is  building  a  bird  house.  As  he  uses  his  tools  he  gets  a 
practical  grasp  of  the  essentials  of  construction  work.  Later  on,  if 
he  keeps  an  eye  on  the  house  after  it  is  set  up,  he  will  learn  a  great 
deal  about  the  habits  of  birds  and  their  likes  and  dislikes.  As  he 


How  to  Understand  the  Birds  { 43 

sees  them  in  and  about  "his"  house,  he  will  experience  a  feeling 
of  pride  and  protective  tenderness. 

But  remember  that  birds  are  often  very  "choosy,"  inspecting 
and  passing  up,  or  simply  ignoring,  an  ideal-looking  residence 
designed  for  them  and  nesting  nearby  in  a  hollow  stump,  post,  or 
tree.  To  be  a  successful  bird-house  "proprietor"  you  need  to  be 
familiar  with  the  habits  and  wants  of  the  birds  you  wish  to  attract, 
and  to  make  a  building  especially  suitable  for  them.  This  cer- 
tainly improves  your  prospects  of  attracting  "tenants."  You  can 
still  expect  surprises,  for  birds  like  to  do  things  their  own  way. 
One  summer  a  neighbor  of  mine  proudly  drew  my  attention  to 
wrens  settling  in  a  home  he  had  built  for  them.  The  following 
year  he  sheepishly  admitted  that  other  wrens  were  using  the  house 
as  a  foundation.  They  were  nesting  on  the  roof! 

The  Hobby  of  Nest  Collecting 

In  doing  their  own  nest  building,  birds  choose  from  a  wide  vari- 
ety of  materials.  The  chipping  sparrow  goes  exploring  for  fine 
roots,  the  robin  prefers  mud  and  grass,  the  ovenbird  fancies  the 
spore  stems  of  mosses,  while  the  Baltimore  oriole  favors  milkweed, 
bark,  and  long  moss.  If  their  favorite  materials  are  not  to  be 
found,  birds  are  ever  resourceful  in  finding  substitutes.  My  son's 
nature  collection  includes  a  chipping  sparrow  nest  that  is  neatly 
lined  with  pig  bristles!  Orioles  are  noted  for  their  fondness  for 
yarn  if  any  happens  to  be  available.  And  there  are  many  other 
examples  of  the  ingenuity  which  birds  lavish  on  their  nests. 

Spring  is  the  season  for  providing  nesting  places.  To  enjoy  the 
hobby  of  collecting  nests,  you  ought  to  wait  until  fall;  for  in  this 
way  you  avoid  removing  a  nest  when  there  is  still  a  chance  that 
the  birds  may  have  a  further  use  for  it. 

Many  birds  are  masters  at  the  art  of  concealment,  and  you  will 
need  all  your  powers  as  a  "nature  detective"  to  find  nests  before 
most  of  the  leaves  have  fallen.  Some  birds,  such  as  the  humming- 
bird, use  a  camouflage  technique  to  protect  their  nests.  Another 
favorite  device,  used  by  the  warbler,  for  example,  is  to  nest  in 
thick  foliage.  Still  another  precaution,  favored  by  some  owls,  is 
to  build  high  in  tall  trees. 


44  ]  How  to  Understand  the  Birds 

When  your  child  collects  deserted  nests  for  a  home  exhibit,  he 
can  give  them  quite  an  impressive  setting  with  a  few  leafy  twigs 
and  a  background  taken  from  the  original  location  of  the  nest. 
To  complete  the  exhibit  appropriately,  add  a  label  giving  the 
species,  time,  and  place  of  the  collection. 

Baby  Birds 

The  Chicken  and  the  Egg 

The  best-known  bird's  t^^  by  far  is  that  of  the  chicken. 
It  is  such  a  common  sight  on  grocery  shelf  and  breakfast  table 
that  it  really  requires  an  effort  of  imagination  on  a  child's  part 
to  think  of  the  egg  in  connection  with  bird  life. 

Yet  if,  in  this  day  of  incubators,  children  could  watch  a  hen 
with  her  brood,  they  would  soon  realize  she  is  one  of  the  best  of 
bird  mothers.  When  she  takes  her  chicks  into  tall  grass  she  clucks 
constantly  so  that  they  will  not  stray  away  from  her.  Finding  a  bit 
of  food,  she  calls  them  quickly  and  they  understand  just  what  she 
means.  Should  a  hawk  appear  overhead,  she  gives  a  warning  cry 
which  sends  the  chicks  scurrying  for  cover.  If  a  rat  or  other  enemy 
threatens  her  brood,  she  will  fight  to  the  limit  of  her  strength 
to  protect  the  chicks. 

A  newly  hatched  chick  wears  an  odd  little  "bump"  on  the  tip 
of  its  upper  mandible,  or  beak.  This  is  the  ''^gg  tooth"  that  the 
baby  used  as  a  pick  to  break  its  way  through  the  eggshell.  After 
the  egg  tooth  has  served  its  purpose  the  chick  has  no  further  use 
for  it  and  it  soon  disappears. 

How  Many  Eggs  Are  Laid 

There  is  an  almost  endless  variety  in  bird's  eggs.  There 
are  big  eggs  and  little  eggs;  white,  colored,  and  spotted  eggs;  eggs 
that  differ  in  shape  and  length  of  time  required  for  incubation. 
And  so  you  need  considerable  information  to  answer  the  simple 
question:  "How  many  eggs  does  a  bird  lay?" 

We  have  no  unconditional  reply  to  this  question.  Each  species 
has  a  mual  number  that  makes  up  a  full  set;  but  differences  will 
still  crop  up.  Northern  thrushes,  for  example,  normally  lay  four 


How  to  Understand  the  Birds 


[45 


eggs,  while  tropical  thrushes  lay  only  two  or  three.  If  a  nest  is 
robbed,  the  bird  will  often  lay  additional  eggs  to  replace  the 
stolen  ones.  There  is  an  historic  case  of  a  brown  woodpecker- 
known  as  the  flicker— laying  seventy-one  eggs  in  seventy- three  days! 

Fantastic  as  this  may  sound,  it  points  up  the  fact  that  constant 
nest-robbing  has  virtually  turned  domestic  fowls  into  egg-laying 
machines.  A  domestic  hen  may  lay  more  than  two  hundred  eggs 
a  season  if  they  are  promptly  taken  away,  thus  assuring  "continu- 
ous performance."  On  the  other  hand,  if  the  eggs  are  left  in  the 
nest  to  be  incubated,  her  production  will  stop  after  fifteen  or 
twenty  eggs. 

The  best  you  can  do,  then,  in  giving  actual  numbers  of  eggs 
that  different  birds  have  in  a  clutch,  is  to  say  that  in  a  full  set  of 
eggs  there  may  be  as  many  as  twenty  or  as  few  as  one. 


THE  AMAZING  HUMMINGBIRD 

The  smallest  of  all  birds,  with  the  tiniest  of  eggs,  the  hummingbird  has  other 
claims  to  fame.  Aside  from  flying  backward  or  remaining  stationary  in  mid-air. 
It  can  move  its  wings  so  rapidly  that  they  become  invisible.  This  incredibly 
rapid  motion  produces  the  sound  that  gives  the  "hummer"  its  name. 


46  ]  How  to  Understand  the  Birds 

The  Size  of  Eggs 

"Which  bird  lays  the  biggest  eggs?"  and  "Which  lays  the 
smallest?"  are  welcome  questions  because  we  have  direct  and 
definite  answers  to  them.  The  ostrich,  largest  of  birds,  lays  the 
largest  eggs;  the  hummingbird,  smallest  of  birds,  lays  the  smallest 

eggs. 

However,  it  does  not  always  follow  that  the  larger  bird  lays 
the  larger  ^^^.  A  bird  whose  chicks  come  forth  in  a  well-developed 
state,  lays  relatively  larger  eggs  than  a  bird  whose  chicks  are  less 
well  developed. 

Among  the  well-developed  babies  are  those  of  our  friend  the 
chicken,  the  grouse,  and  the  spotted  sandpiper.  When  they  hatch 
they  are  already  covered  with  a  soft  down.  Their  eyes  open  imme- 
diately and  in  no  time  at  all  they  can  toddle  about  and  follow 
their  mother.  Before  long  they  learn  to  pick  up  and  eat  their  own 
food.  We  term  this  kind  of  bird  "precocial,"  a  word  related  to 
"precocious."  Birds  that  hatch  in  a  more  helpless  state  are  naked 
or  at  best  have  a  scant  covering  of  down.  They  are  blind  at  first 
and  are  dependent  on  their  parents  for  at  least  a  week— usually 
much  longer.  Such  birds  are  known  as  "altricial,"  from  the  Latin 
word  for  "nourishers." 

"Baby  Sitters" 

The  length  of  time  needed  for  incubation  varies  with  dif- 
ferent species.  The  English  sparrow  takes  twelve  or  thirteen  days; 
the  robin,  thirteen  or  fourteen  days;  the  fish  hawk,  about  four 
weeks.  In  some  families  the  duty  of  sitting  on  the  eggs  is  shared 
by  both  parents;  in  others,  it  falls  entirely  to  the  lot  of  the  mother. 
There  is  one  curious  family  in  which  the  eggs,  once  they  have 
been  laid  by  the  female,  become  the  sole  responsibility  of  the 
male.  He  incubates  the  eggs  unaided,  though  the  mother  stays 
nearby  and  shows  continued  interest  in  her  family.  These  birds 
are  the  phalaropes,  found  in  many  parts  of  North  America. 

Bringing  Up  Baby 

Helpless  baby  birds  require  an  extraordinary  amount  of 
care,  and  perhaps  because  it  helps  to  build  in  themselves  a  sense 


How  to  Understand  the  Birds  [  47 

of  the  security  of  parental  care  and  affection,  children  greatly 
enjoy  hearing  about  the  devoted  family  life  of  birds.  How  proud 
the  mother  hen  is  of  her  chicks  as  she  struts  about  the  barnyard, 
clucking  loudly  to  call  attention  to  her  brood!  In  the  wilds,  where 
danger  constantly  threatens,  the  mother  bird's  behavior  may  be 
quite  the  opposite— she  does  everything  possible  to  make  her 
brood  inconspicuous.  A  grouse,  sensing  an  intruder,  will  go  to 
the  extreme  of  chirping  pitifully  while  thrashing  along  the  ground 
as  if  hurt.  This  serves  two  purposes.  Her  cry  warns  the  young  to 
remain  quiet  or  escape  from  the  danger,  and  her  movements  divert 
attention  from  her  little  family. 

How  Bird  Babies  Are  Fed 

Bird  babies  have  enormous  appetites.  Until  they  are  able 
to  take  care  of  themselves,  their  parents  must  find  and  bring  them 
food.  The  fledglings  usually  feed  on  insects,  even  though  many  of 
them  will  grow  up  to  be  seed-eaters.  In  species  where  the  young 
are  most  helpless— the  mourning  dove,  for  example— the  parent 
first  swallows  the  food  and  then  feeds  it  to  them  in  partly  digested 
form.  That  is  why  one  of  these  birds,  unlike  so  many  other  bird 
parents,  is  never  seen  flying  back  to  the  nest  with  food  in  its  bill. 

Children  occasionally  have  the  good  fortune  to  watch  baby  birds 
being  fed.  More  often  the  children  see  pictures  of  the  birds  at 
feeding  time,  and  they  may  notice  that  feeding  techniques  vary 
with  different  birds.  The  most  common  method  is  for  the  parent 
to  push  its  bill  down  the  baby's  throat— a  method  that  prevents 
any  live  insect  from  escaping.  With  pelicans  and  certain  other 
species  that  regurgitate  food,  the  process  is  reversed:  The  baby 
puts  its  head  in  its  mother's  throat  pouch  or  takes  food  from  her 
bill.  The  babies'  need  for  water  is  satisfied  by  the  moisture  in  their 
solid  food. 

Parents  often  continue  feeding  the  young  after  they  have  left 
the  nest;  but  at  this  point  the  feeding  methods  are  no  longer  so 
painstaking.  The  swallows  are  particularly  interesting  to  observe 
at  this  stage  of  development.  While  in  the  nest,  the  young  bird 
has  food  carefully  placed  down  its  throat.  But  once  the  fledgling 
is  able  to  hop  away  from  the  nest,  it  must  be  on  the  alert  with 


48  ]  How  to  Understand  the  Birds 

bill  opened  upward,  for  the  parents  merely  drop  food  to  it  with- 
out pausing  in  their  flight.  When  the  young  swallows  start  to  fly, 
this  catch-as-catch-can  feeding  continues  while  the  parents  and 
the  young  birds  as  well  are  in  full  flight. 

Proper  manners,  as  taught  to  our  children,  are  out  of  place  as 
far  as  baby  birds  are  concerned.  Usually  the  aggressive  one  that 
stretches  its  neck  farthest  and  cries  the  loudest  is  the  one  that 
is  fed— until  another  member  of  the  family  becomes  more  "grabby.** 
However,  the  parent,  with  a  kind  of  rough  justice,  usually  looks 
into  the  youngster's  mouth  after  each  feeding;  if  a  morsel  has  not 
been  swallowed  instantly,  the  older  bird  snatches  it  back  and 
turns  its  attention  to  another  baby. 

Getting  Ready  to  Leave  the  Nest 

Some  babies— those  of  chickens,  for  example— are  covered 
with  down  and  able  to  run  about  when  newly  hatched.  The 
parents  may  keep  them  under  their  wings,  "brooding"  them 
over  a  period  of  five  or  six  weeks.  Other  kinds  of  birds  also  "brood" 
while  the  babies  are  in  the  nest,  but  never  after  they  have  started 
to  fly.  Brooding  protects  the  young  ones  from  the  cold— and  from 
excessive  heat  as  well,  as  it  prevents  their  being  overheated  in  a 
nest  unprotected  from  the  sun. 

As  the  baby  birds  develop  feathers,  their  responsibilities  grow. 
They  preen  their  feathers  and  begin  to  exercise,  concentrating  on 
stretching  their  wings.  Often  they  practice  "taking  off"  before 
leaving  the  safety  of  the  nest. 

Though  birds  fly  by  instinct,  the  first  flight  generally  requires 
considerable  parental  coaxing.  It  may  be  no  more  than  a  flutter 
to  a  nearby  limb  or  it  may  be,  as  in  the  case  of  swallows,  a  sus- 
tained and  graceful  performance.  Song  sparrows  and  others  are 
ready  to  try  their  wings  only  a  week  after  hatching,  while  the 
wandering  albatross  has  to  be  forced  out  by  its  parents  to  make 
room  for  a  new  brood— nearly  a  year  later.  But  whatever  the 
amount  of  time  involved,  the  youngsters  have  flourished  on  the 
solicitous  care  of  their  parents,  and  are  now  ready  to  face  life 
on  their  own.

of  Bird  Watching 


ATCHiNG  FOR  BIRDS  Can  givc  Sparkle  to  an 
otherwise  ordinary  walk  through  a  park- 
it  can  offer  an  inducement  for  extensive  hiking— and  it  can  add 
zest  to  your  auto  trips.  If  you  do  not  try  it,  you  will  miss  a  world 
of  fun.  For  children,  it  is  one  of  the  most  delightful  of  pastimes. 

The  best  way  for  you  to  carry  on  bird  watching  depends  largely 
on  the  age  of  your  children.  Obviously  you  cannot  expect  a  child 
of  kindergarten  age  to  adapt  himself  to  an  excursion  in  the  woods 
where  you  hope  to  see  the  less  common  birds  in  their  natural 
surroundings;  a  young  child  is  too  restless  to  maintain  the  neces- 
sary quiet.  Also,  since  he  is  more  interested  in  what  birds  do  than 
in  what  they  are  called,  the  most  ordinary  bird  will  appeal  to 
him  just  as  strongly  as  a  rare  species.  Thus  you  may  find  it  best 
to  start  your  observations  with  the  "everyday"  birds  around  your 
home. 

A  small  child  loves  to  answer  easy  questions.  And  questions 
can  provide  the  motivation  here  if  the  presence  of  birds  on  the 
lawn  or  in  the  park  is  not  motivation  enough.  You  might  start 
with  some  of  these  queries,  leaving  out  bird  names  unless  the 
child  is  ready  for  them:  Do  the  birds  walk  (as  blackbirds  do), 
run  (like  robins),  or  hop  (like  sparrows)  ?  Do  they  keep  together 
in  flocks  (like  waxwings,  for  example) ,  or  do  they  prefer  to  be 
alone?  Do  they  seem  to  talk  to  each  other,  or  do  they  concentrate

on  feeding?  Do  they  hunt  worms  or  look  for  seeds  for  their  food? 
You  can  proceed  from  these  questions  to  others  that  will  come 
to  you  naturally  enough  as  you  read  what  this  book  has  to  say 
about  birds.  All  you  need  is  a  start.  Your  child's  rich  imagination 
will  carry  you  the  rest  of  the  way. 

How  TO  Get  the  Most  Out  of  Bird  Walks 

Once  boys  and  girls  have  become  interested  in  watching 
birds  at  home,  they  are  usually  eager  to  go  farther  afield.  Then  you 
will  enjoy  your  trip  a  lot  more  if  you  are  forearmed  with  some 
general  knowledge:  What  birds  may  be  found  where? 

For  example:    In  orchards  and  gardens  you  are  likely  to  find 
bluebirds,  mockingbirds,  screech  owls,  downy  woodpeckers,  chicka- 


fHE  BRILLIANT  SCARLET  TANAGER 

Whh  hl$  striking  red  body  and  black  wings  and  tail,  the  male  tanager  Is  on© 
of  the  most  brilliant  birds  of  North  America.  The  female,  olive-colored,  is  not 
nearly  so  pretty,  but  she's  the  one  that  gathers  twigs  and  weeds  to  build  the 
nest  in  an  oak  or  orchard  tree.  Here  she  lays  three  or  four  bluish-white  eggs. 


dees.  In  open  meadows,  look  for  bobolinks  and  crows;  in  damp 
meadows,  red-winged  blackbirds.  Along  rivers  and  by  lakes  and 
ponds  you  may  find  kingfishers,  swallows,  and  phoebes.  At  woods'

edges  there  are  white-throated  sparrows,  field  sparrows,  wood 
pee  wees,  scarlet  tanagers,  and  some  owls;  in  deeper  woods,  barred 
owls,  ovenbirds,  hermit  thrush,  ruffed  grouse. 

Swamps  and  marshes  are  the  places  for  herons,  bitterns  and 
rails,  while  near  large  ponds  and  lakes  you  may  expect  ducks, 
fish  hawks,  and  bald  eagles.  Seashore  and  mud  flats  are  the  setting 
for  sandpipers  and  avocets. 

This  greatly  shortened  list  of  birds  and  their  customary  home 
grounds  suggests  how  you  may  "line  up"  the  birds  of  your  locality 
before  starting  on  a  bird  walk.  You  will  have  an  idea  of  where 
to  look  for  certain  types  of  birds,  so  that  you  can  map  out  a  plan 
of  action. 

The  best  time  to  go  is  early  morning;  soon  after  sunrise  bird 
activities  slow  down  and  do  not  resume  until  late  afternoon.  On 
early-morning  walks,  avoid  traveling  east,  as  the  low-lying  sun 
in  your  eyes  makes  it  hard  to  see  birds.  Hawks,  ducks,  and  water- 
fowl are  active  throughout  the  day  and  you  may  often  observe 
them  when  other  birds  are  quiet. 

There  is  no  special  season  for  bird  watching.  The  great  attrac- 
tion of  spring  is  the  birds  migrating  north;  summer  offers  nesting 
birds  and  the  appearance  of  the  young;  fall  is  the  time  for  the 
flocks  to  wing  south;  winter  is  almost  best  of  all  with  the  hardy 
birds  showing  themselves  boldly  as  they  seek  food  among  snowy 
surroundings. 

An  interested  pair  of  eyes  is  the  only  essential  equipment  you 
need  for  bird  watching.  But  good  field  glasses  or  binoculars  are 
really  valuable  in  identifying  species  and  they  greatly  enhance 
the  pleasure  of  a  trip  for  any  child  old  enough  to  use  them. 

You  can  get  more  out  of  a  bird  walk,  also,  if  you  bring  along 
a  pocket  guide  of  birds  for  occasional  reference  and  also  a  note- 
book for  making  brief  entries  about  birds  that  you  cannot  identify 
on  the  spot.  Thus  you  can  note  size  (comparing  your  bird  to  a 
robin  or  other  familiar  species) ;  you  can  mention  whether  the 
tail  is  outstandingly  long  or  short;  you  can  list  the  bird's  color 
and  any  conspicuous  markings;  you  can  describe  its  actions  (walk- 
ing, hopping,  up-and-down  or  zigzag  flight,  posture  on  tree  trunk) , 
and,  of  course,  the  kind  of  surroundings  where  you  saw  it.  With

this  information  handy,  you  can  consult  reference  books  with 
a  good  chance  of  identifying  the  unknown  bird. 

Some  Bird  Neighbors 

Robins  Mean  SpRirjc  is  Here 

If  you  have  a  birdbath,  robins  are  very  likely  to  be  among 
those  patronizing  it.  They  enjoy  bathing  and  are  friendly  and 
trusting.  The  robin  is  so  well  known  that  it  is  commonly  used  as 
a  basis  for  comparison  with  other  birds  that  are  described  as 
"larger  than,"  "smaller  than,"  or  "about  the  size  of,"  a  robin. 
Its  length  is  about  ten  inches  from  the  tip  of  its  bill  to  the  tip 
of  its  tail. 

In  most  of  the  United  States  (aside  from  the  Gulf  Coast),  and 
in  Canada,  robins  are  "summer  residents";  their  return  to  familiar 
nesting  sites  is  a  sign  of  spring.  You  are  likely  to  see  them  then, 
hurrying  about  in  search  of  building  material.  (Robins  never 
walk;  they  run.)  They  pick  up  coarse  grasses,  rootlets,  and  other 
serviceable  bits  in  their  bills  and  fly  to  the  home  base.  Here  they 
add  their  plunder  to  former  collections.  After  putting  it  down 
they  hop  on  it  and  rapidly  work  it  with  their  feet  until  it  is 
wedged  tightly  in  place.  Even  as  they  do  this,  they  turn  their 
bodies  from  side  to  side,  squatting  down  against  the  nest.  In  this 
way  they  form  a  depression  that  is  really  "made  to  measure." 
Both  male  and  female  share  in  the  construction  work. 

The  female  robin  lays  from  three  to  five  greenish  blue  eggs  in 
the  compact  little  home.  Mother  and  father  take  turns  sitting 
on  the  eggs  to  keep  them  warm  day  and  night.  When  the  young 
robins  appear  in  about  two  weeks  the  parents  continue  their 
devoted  care,  feeding  them  insects  and  guarding  them  to  the  best 
of  their  ability  from  such  enemies  as  cats,  squirrels,  and  snakes. 
By  late  June  the  robin  family  may  be  really  sizable,  for  there  is 
likely  to  be  a  second  brood  in  the  nest.  The  young  of  the  first 
brood  now  go  each  night  with  the  adult  male  to  some  favorite 
roosting  place.  The  mother,  busy  caring  for  her  second  lot  of 
triplets  or  quadruplets,  is  not  forgotten  by  her  mate,  who  may 
return  each  day  to  help  her  with  her  duties. 


The  Delightful  Hobby  oj  Bird  Watching  f  53 

If  you  glimpse  a  robin  still  dressed  in  "baby  clothes"  you  will 
notice  that,  unlike  adults  with  their  solid  black-and-orange  color- 
ing, it  has  a  spotted  breast.  Here  you  have  a  clue  to  the  robin's 
relationship  to  other  birds.  Many  of  us  know  that  adult  thrushes 
have  spotted  breasts  and  we  can  correctly  assume  that  robins  and 
thrushes  belong  to  the  same  family.  The  bluebird  is  another 
famous  close  relative. 

Sparrows  Are  Pleasant  Neighbors 

The  sparrow  family  has  been  discredited  to  some  extent 
in  the  United  States  and  Canada  by  a  species  of  weaver  bird  that 
was  imported  a  hundred  years  ago  from  England  and  became 
generally  known  as  the  English,  or  house,  sparrow.  This  * 'sparrow" 
spread  over  the  continent  and  in  many  places  it  drove  away  the 
more  attractive  bluebirds  and  purple  martins. 

"Only  a  sparrow,"  may  be  your  child's  attitude  toward  this 
bird  family— it  is  easy  for  youngsters  to  acquire  the  general  preju- 
dice against  these  birds.  As  he  becomes  acquainted  with  sparrows, 
however,  he  will  find  that  some  of  them  are  surprisingly  attractive 
and  that  some  sing  sweet,  melodious  songs.  The  white-crowned 
sparrow  is  probably  the  most  handsome,  with  a  striking  black 
and  white  crown,  a  gray  breast  with  no  throat  markings,  and  an 
erect  posture.  It  is  found  all  over  North  America  but  it  is  much 
more  common  in  the  West  than  in  the  East. 

The  song  sparrow  is  noted  more  for  its  song  than  for  its  apj>ear- 
ance.  Its  cheerful  Tea-tea-tea!  Polly-put-the-kettle-on,  heard 
frequently  in  early  spring,  is  most  distinctive.  The  marking  that 
distinguishes  it  from  other  sparrows  is  a  large  brown  spot  centered 
on  a  streaked  breast.  It  has  a  long  rounded  tail  which  pumps  up 
and  down  as  it  flies. 

You  are  most  likely  to  see  little  "chippy,"  the  chipping  sparrow, 
in  suburban  areas.  It  seems  to  prefer  lawns  or  pasture  lands  to 
wilder  country  and  it  often  nests  in  dooryards,  hedges,  and  shrub- 
bery. It  is  among  the  smallest  of  sparrows  (about  half  as  long  as 
a  robin),  and  its  reddish  crown,  black  bill,  and  white  line  over 
the  eye  and  a  black  one  through  the  eye  are  its  distinguishing 
marks.  Though  this  sparrow  spends  most  of  its  time  on  the  ground. 


54  ]  The  Delightful  Hobby  of  Bird  Watching 

it  often  perches  on  some  lofty  spot  to  deliver  its  song— a  rapid 
succession  of  metallic-sounding  chips. 

Jays 

If  you  travel  from  coast  to  coast,  there  are  few  places  where 
you  will  lose  sight  of  the  jay  family.  Of  its  various  members  the 
blue  jays  are  most  common,  most  widespread  and  probably  the 
boldest.  Their  striking  markings  make  them  easy  to  recognize, 
and  anywhere  from  the  Atlantic  Coast  to  the  Rocky  Mountains 
you  may  see  them  along  highways  and  byways.  In  bright  blue 
plumage  marked  with  stripes  and  patches  of  black  and  with  clear 
white,  they  fly  with  a  regular  series  of  wing  flappings.  Or  else  they 
strut  and  swagger  on  the  ground,  scolding  loudly  at  any  bird, 
man,  or  beast  that  seems  likely  to  interfere  with  their  activities. 
Usually  they  have  a  raucous  cry,  but  they  can  also  produce  flute- 
like notes  as  well  as  a  noise  resembling  the  sound  of  nutcracking. 
Sometimes  they  imitate  the  cry  of  the  red-shouldered  hawk. 

In  the  West,  the  Steller  jay  is  slightly  larger  than  the  blue  jay,  and 
you  can  distinguish  it  by  its  black  head,  throat  and  breast  and  itf 
long  black  crest.  The  "California"  jay  (also  found  in  Florida)  has  a 
blue  cap,  back,  wings,  and  tail. 

Crows 

The  chances  are  your  child  has  been  able  to  recognize  a 
crow  for  a  long  time,  if  only  from  seeing  pictures  of  this  black 
bird  in  connection  with  scarecrows  ever  since  he  was  of  nursery 
school  age.  The  crow  is  also  one  of  the  easiest  birds  to  "spot" 
in  fields  and  woods  because  of  its  large  size  and  its  intense  black 
coloring,  identical  in  male  and  female.  You  are  likely  to  see  crows 
near  farms;  unfortunately,  their  taste  runs  to  such  crops  as  corn 
and  wheat  as  well  as  fruit. 

Crows  are  also  fond  of  the  eggs  and  fledglings  of  thrushes  and 
meadow  larks,  game  birds,  and  even  poultry.  That  is  why  the 
crow  is  in  great  disfavor  with  farmers  and  with  the  champions 
of  songbirds.  But  *Teck*s  bad  boy"  of  the  bird  world  though  it 
may  be,  the  crow  is  a  prime  favorite  with  children.  And  we  must 
admit  that  with  all  the  damage  crows  cause,   they  do  make  up

[65 


for  it  by  eating  beetles,  caterpillars,  and  slugs— all  of  them  menaces 
to  gardens,  orchards,  and  grainfields. 

Cardinals  for  Color 

You  can  recognize  a  male  cardinal  as  easily  as  the  crow, 
for  it  is  almost  as  intensely  red  (the  color  we  associate  with 
cardinals  of  the  Church)  as  the  crow  is  black.  There  are  very 
few  red  birds  in  North  America,  and  the  cardinal  is  the  only  one 
with  a  crest.  Even  its  heavy  bill  is  red,  though  around  the  base 
there  is  a  patch  of  black  that  extends  back  through  its  eyes  and 


% 


THE  COLORFUL  CARDINAL 

The  male  cardinal  is  an  eye-filling  red  from  bill  to  tati  tip,  with  the  exception  of 
a  touch  of  black  at  his  big,  efficient-looking  beak.  His  "windswept"  crest  mokes 
him  even  more  conspicuous.  In  wintertime  he  presents  a  colorful  contrast  to  snowy 
landscapes.   But   his   musical    coll    mokes   him    a   welcome    visitor   in    any   season. 


56  ]  The  Delightful  Hobby  of  Bird  Watching 

down  its  throat.  Though  the  female  has  the  crest  and  red  bill  of 
the  male,  her  plumage  is  light  brown. 

Cardinals  are  not  commonly  seen  in  New  England  or  on  the 
Pacific  Coast,  but  in  other  sections  of  the  United  States  you  may 
come  on  them  anywhere— in  suburbs,  towns,  or  open  country.  As  a 
rule  they  are  * 'permanent  residents"  of  whatever  area  they  live 
in,  and  in  the  northern  part  of  their  range  they  endure  many  a 
severe  winter  while  creating  scenes  of  striking  beauty:  crimson 
feathers  against  a  snowy-white  background. 

Goldfinches— Our  Wild  Canaries 

You  may  call  them  ''wild  canaries"  as  you  see  a  group  of 
goldfinches  chattering  and  twittering  on  a  lawn.  They  suggest 
these  pet  birds  because  of  their  yellow  coloring,  their  small  size, 
and  their  pleasant  song.  Actually  they  are  closely  related  to  the 
canary  and  also  to  native  sparrows. 

In  flight  goldfinches  are  recognizable  by  their  long  bounding 
motion,  which  may  remind  a  youngster  of  a  roller-coaster  ride. 
At  each  dip  they  seem  to  call  Per-chick-o-ree,  per-chick-o-ree.  They 
travel  around  in  small  groups  during  breeding  season.  Goldfinches 
may  be  found  in  fields  and  meadows  throughout  temperate  North 
America.  Like  the  cardinals,  they  are  usually  permanent  residents 
of  one  region— although  some  goldfinches  travel  a  bit  south  to 
escape  the  most  severe  winter  weather. 

Chickadees 

If  you  furnish  a  winter  feeding  station  for  birds,  you  are 
quite  likely  to  have  chickadees  among  your  patrons.  The  easiest 
way  to  recognize  this  plump  little  black-and-white  bird  is  by  its 
black  cap  and  bib.  In  the  South  there  is  the  Carolina  chickadee, 
only  four  and  a  half  inches  long;  and  in  the  West,  a  chestnut- 
backed  chickadee  with  a  dull  brown,  rather  than  black,  cap. 

Chickadees  are  commonly  found  around  farms  and  country 
homes.  In  warm  weather  they  seclude  themselves  in  the  woods, 
nesting  in  holes  in  trees;  in  winter  they  are  out  scouting  and 
seem  especially  grateful  for  "handouts"  from  human  friends.

Hummingbirds— Smallest  of  the  Birds 

Most  children,  loving  tiny  things  as  they  do,  are  delighted 
with  hummingbirds,  the  smallest  birds  in  the  world.  Those  found 
in  the  United  States  and  Canada  range  from  about  three  and  a 
half  to  four  and  a  half  inches  in  length. 

West  of  the  Mississippi  the  hummingbird  may  be  lured  near 
homes  by  an  abundance  of  flowers  and  any  small  stream  of  water. 
On  the  west  coast  it  nests  in  porch  vines  and  is  frequently  satisfied 
with  birdbaths  or  lawn  spiinklers  for  its  water  supply.  The  ruby- 
throated  hummingbird,  the  only  one  that  frequents  the  East,  is 
not  quite  so  sociable;  but  it  may  be  attracted  to  a  garden  by 
brightly  colored  tubes  of  sugar  water.  You  can  make  a  humming- 
bird feeder  with  a  medium-size  vial.  Wrap  this  with  red  ribbon 
or  crepe  paper  and  fasten  it  with  a  thin  wire  to  a  twig  in  the  garden. 
Fill  the  vial  with  a  mixture  of  one  part  sugar  to  two  parts  water. 

Hummingbirds  usually  nest  in  fruit  and  shade  trees,  and  their 
well-camouflaged  home  is  so  small  that  it  could  easily  be  covered 
by  a  fifty-cent  piece.  The  female  builds  the  deeply  cupped  nest  by 
herself.  While  she  is  busy  molding  and  shaping  it  with  her  feet 
and  bill,  her  mate  disappears  from  the  scene. 

Newly  hatched  hummers  look  more  like  black  insects  than 
birds,  and  watching  a  mother  feed  them  is  quite  an  experience. 
She  gives  them  food  in  a  series  of  stabbing  motions  as  she  jabs 
her  long  beak,  filled  with  nectar  and  insects,  down  their  throats. 
She  not  only  feeds  them  well;  she  is  ever  ready  to  defend  them 
and  will  even  attack  an  enemy  as  large  as  a  hawk  if  it  comes  near. 

Hummingbirds  have  exceptional  flying  powers.  Some  move 
their  wings  so  fast  that  it  is  quite  impossible  for  the  human  eye 
to  see  them.  Hummers  are  among  the  very  few  birds  that  can 
fly  backwards  (the  phoebe  and  the  oriental  sunbird  are  the 
others) ,  and  they  can  "stand  still'*  in  the  air.  They  get  their 
name  from  the  hum  of  their  wings  which  can  be  heard  during 
their  rapid  darting  flight  as  well  as  when  they  hover. 

Meadow  Larks 

When  you  walk  through  meadows  or  marshes  you  may  be 
startled  by  a  large  brownish  bird  rising  out  of  the  grass  in  front

THE  MEADOW  LARK -AN  AMERICAN  SYMBOL 

This  large  pudgy  brownish  bird  has  a  lovely  flutelike  song  and  likes  to  nest  in  the 
long  grasses  of  meadowbanks  along  streams.  A  useful  bird,  it  preys  on  great 
quantities  of  pernicious  insect  pests.  It  is  found  in  so  many  ports  of  our  land 
that  it  might  well  replace  the  eagle  as  an  American  symbol. 

of  you.  If  you  notice  a  striped  head  and  white  outer  tail  feathers 
as  it  flies  away,  the  chances  are  you  have  flushed  a  meadow  lark. 
This  bird  seems  to  have  great  faith  in  long  grasses  for  protection 
(even  nesting  among  them  on  the  ground).  You  may  walk  up 
to  within  a  few  feet  of  a  meadow  lark  before  it  will  take  wing. 
In  the  fall,  meadow  larks  of  the  North  gather  in  flocks  and  migrate 
to  southern  swamps. 

Baltimore  Orioles 

The  Baltimore  oriole  is  a  striking  example  of  how  our 
familiar  roles  may  be  reversed  in  the  bird  world:  The  male  is 
noted  for  his  beauty,  the  female  for  her  skill  in  home  construc- 
tion. You  can  easily  sight  the  brilliant  orange  and  black  plumage 
of  the  male  even  when  he  flits  among  tree  branches.  His  olive- 


The  Delightful  Hobby  of  Bird  Watching  [  59 

yellow  mate  looks  confusingly  like  the  female  orchard  oriole  and 
somewhat  like  the  female  scarlet  tanager;  the  only  time  it  is  easy 
to  identify  her  is  when  she  is  with  her  handsome  husband. 

You  may  best  appreciate  the  female's  building  prowess  after 
the  family  has  migrated  southward  and  you  see  the  nest  hold  up 
through  wind,  snow,  and  sleet.  She  works  with  such  plant  fibers 
as  the  inner  bark  of  milkweed,  as  well  as  string  and  other  avail- 
able materials,  weaving  them  skillfully  together.  The  nest,  a  large 
one,  is  very  unusual  in  being  fastened  to  a  branch  at  its  rim,  with 
the  bottom  hanging  free.  Vireos  are  the  only  other  birds  that 
build  this  type  of  nest,  but  theirs  is  less  than  two  inches  deep  on 
the  inside— much  smaller  than  an  oriole  structure. 

CowBiRDs  Follow  Cattle 

You  can  find  cowbirds  in  pastures  and  woodlands.  Often 
small  flocks  of  them  follow  cattle.  They  find  good  hunting  by 
catching  insects  that  infest  the  big  animals;  the  birds  alight  on 
the  cows*  backs  to  obtain  their  prey.  The  cowbird,  smallest  of  our 
native  blackbirds,  is  undistinguished  in  appearance.  In  a  good 
light  you  can  see  that  the  male's  head  is  a  rich  brown  rather  than 
black,  while  the  female  and  young  have  gray-brown  plumage. 

Though  ordinary  enough  in  appearance,  the  cowbird  has  an 
extraordinary— and  most  dishonest— way  of  providing  for  its  young. 
It  does  not  build  a  nesti  Instead,  the  female  merely  deposits  an 
€:^g  in  the  home  of  a  warbler,  song  sparrow,  or  other  bird,  biding 
her  time  until  the  owner  of  the  nest  is  away. 

In  due  course  the  foster  mother  hatches  the  cowbird  ^^^  with 
her  own  eggs.  The  cowbird  is  invariably  larger  than  its  legitimate 
nest-mates.  It  can  therefore  poke  its  head  over  theirs  to  be  first 
in  line  whenever  the  mother  appears  with  food.  The  result  is 
that  the  intruder  grows  faster  and  often  pushes  the  little  ones 
out  of  the  nest  to  die  of  starvation.  Occasionally  a  victimized  bird 
discovers  the  fraud  in  time  and  destroys  the  impostor  ^g^y  or  else 
abandons  the  nest  to  build  a  new  one  and  lay  a  new  clutch  of  eggs. 

The  yellow  warbler  has  an  ingenious  way  of  dealing  with  the 
cowbird's  maneuvering.  If  she  discovers  a  strange  e^g,  she  simply 
builds  another  nest  over  the  first  one.   If  still  another  cowbird 


6o] 


The  Delightful  Hobby  of  Bird  Watching 


egg  is  "planted"  in  the  second  nest,  she  builds  a  third  on  top  of 
that.  Warblers  have  been  known  to  build  up  to  five  nests  in 
this  way! 

Mockingbirds  Don't  Always  Mock 

The  name  of  this  justly  famous  songbird  is  misleading  in  a 
way.  Individual  birds  may  "mock"  the  notes  of  other  birds  and 
even  the  bark  of  a  dog  or  the  meow  of  a  cat;  but  occasionally  the 
birds  stick  to  their  own  notes.  Aside  from  its  imitations,  the 
mockingbird  has  a  lovely  liquid  song  that  deserves  appreciative 
recognition  in  its  own  right.  Mockingbirds  not  only  have  song 
fests  by  day;  they  are  most  eloquent  on  moonlit  nights. 

While  the  mockingbird  is  primarily  a  southerner,  some  birds 
venture  to  feeding  stations  as  far  north  as  New  England.  The 
mockingbird  has  an  over-all  grayish  tone  and  in  flight  shows 
flashes  of  black  and  white  in  its  wings.  The  mockingbird  is  about 
the  size  of  a  robin,  though  not  so  plump,  and  it  has  a  long  tail. 


THE  MOCKINGBIRD-EXPERT  AT  MIMICRY 

Though  moonlit  nights  inspire  the  mockingbird  to  a  hountingiy  beautiful  song 
with  exquisite  variations,  it  has  a  great  gift  for  sardonic  mimicry  of  other  birds. 
Its  lifelike  imitation  of  a   hawk's  shriek   is  as  convincing   as  ''the    real   thing."

Whippoorwills— The  Invisible  Singers 

Like  the  mockingbird,  the  whippoorwill  is  noted  above 
all  else  for  its  voice.  While  you  may  frequently  hear  its  call,  you 
will  rarely  see  the  bird  itself.  It  usually  lives  in  a  river  valley  or 
in  a  meadow  if  water  is  nearby,  stays  close  to  the  ground,  and 
does  not  become  active  until  the  sun  goes  down.  Then  it  starts  to 
feed  on  insects  during  low  short  flights,  between  which  it  gives 
the  oft  repeated  call  whip-poor-WILL,  whip-poor-WILL.  The 
bird's  brownish  plumage  makes  it  practically  invisible  when  it  is 
resting  on  dry  leaves. 

Woodpeckers— Good  Creepers  and  Climbers 
The  name  of  the  "redheaded"  woodpecker  appeals  so 
strongly  to  children  that  this  bird  almost  seems  to  be  the  out- 
standing member  of  the  tribe.  However,  this  woodpecker  is  only 
one  of  many:  There  are  at  least  375  varieties.  The  woodpecker 
is  found  in  all  parts  of  the  world  except  the  Australian  region 
and  Madagascar.  There  are  twenty-four  species  in  North  America. 
The  downy  woodpecker  which  is  at  home  in  our  woods  and 
parks  is  probably  the  most  widespread  and  common.  One  of  the 
smallest  of  the  family,  it  is  a  plain  black  and  white  except  for  the 
red  patch  the  male  wears  on  the  back  of  its  head.  It  is  also  one  of 
the  friendliest,  and  an  eager  visitor  at  winter  feeding  stations  if 
you  provide  suet  for  it. 

Woodpeckers  are  well  adapted  for  creeping  and  climbing,  as 
they  have  two  toes  directed  forward  and  two  backward  to  assist 
them  in  clinging  to  an  upright  surface.  The  stifiE-pointed  tail 
feathers  serve  as  a  prop.  Their  other  notable  adaptation  is  the 
strong  sharp  bill  with  which  they  can  chisel  away  wood  to  expose 
grubs.  This  bird's  specialized  tongue  is  also  useful:  it  can  be 
extended  some  distance  and  has  a  horny  spearlike  tip  on  which 
the  food  is  impaled  and  then  drawn  into  the  woodpecker's  bill. 

Owls— Birds  of  the  Night 

Even  before  a  child  hears  "The  Owl  and  the  Pussycat," 
his  imagination  may  be  captured  by  this  dignified  bird.  Since 
owls  are  creatures  of  the  night  they  are  seldom  seen;  but  their 
hoots,  shrieks,  and  other  distinctive  calls  often  betray  their  pres- 


62  ]  The  Delightful  Hobby  of  Bird  Watching 

ence  in  a  neighborhocxi.  Most  owls  are  woodland  birds,  though 
some  make  their  homes  in  steeples,  towers,  bams,  and  other  out- 
buildings; some  owls  prefer  marshes  and  plains. 

Many  people  have  mistaken  ideas  about  owls.  One  of  these 
notions  is  that  owls  cannot  see  in  the  daytime.  It  is  true  that 
their  sight  is  keenest  at  night,  when  they  do  their  hunting;  but 
they  can  use  their  big  staring  orbs  from  sunrise  to  dark  if  they 
wish.  These  eyes  are  placed  in  their  sockets  in  an  odd  manner, 
being  fixed  in  such  a  way  that  the  bird  cannot  look  from  one 
place  to  another  by  merely  rolling  its  eyeballs.  In  order  to  see  to 
the  side,  it  must  turn  its  head  in  that  direction.  As  a  result,  its 
efforts  to  keep  an  object  in  view  may  make  the  owl  seem  to  be 
"unscrewing"  its  head. 

Owls  vary  greatly  in  size  according  to  species.  Whereas  the 
screech  owl  is  no  more  than  ten  inches  long,  the  great  homed  owl 
may  reach  a  maximum  of  twenty-three  inches.  Both  of  these  have 
conspicuous  ear  tufts.  The  great  horned  owl  seeks  wild,  heavily 
forested  regions.  The  screech  owl  frequently  lives  near  dwellings, 
in  shade  trees  of  village  streets  or  suburban  lots.  On  occasion  it 
will  accept  the  hospitality  of  a  bird-box  home.  Its  plumage  is 
rather  odd:  its  color— gray  or  reddish— offers  no  clue  as  to  sex,  age, 
or  season.  Some  owls  simply  have  reddish-brown  feathers  while 
others  have  grayish-brown  ones. 

Hawks— More  Friends  Than  Foes 

You  can  perhaps  best  recognize  the  large  and  varied  hawk 
family  by  actions  and  sounds.  Hawks  are  solitary  birds  except 
during  the  migration  season.  Ordinarily  you  may  see  one  of  them 
soaring  in  wide  circles  high  overhead,  scanning  the  ground  below 
for  a  possible  victim.  When  it  spots  a  quarry  it  swoops  down, 
strikes  the  prey  with  its  feet  and  tears  it  to  pieces  with  its  bill. 
Its  loud,  startling  cry  seems  very  suitable  to  its  fierce  nature. 

Because  of  the  many  similarities  among  different  species,  it  is 
not  always  simple  to  tell  them  apart.  Sometimes  you  can  identify 
the  red-tailed  hawk  by  the  feature  which  gives  it  its  name,  even 
when  it  is  flying  quite  high  above  you.  Its  tail  is  frequently  slanted 
in  flight,  and  especially  on  a  sunny  day  the  red  tones  on  the  upper

THE  RED-TAILED  HAWK-BEHER  THAN   ITS  REPUTATION 

With  their  sharp  eyes  and  ability  to  fly  swiftly  and  tirelessly,  the  ropaclous 
hawks  are  ideally  adapted  to  be  birds  of  prey.  Though  falsely  accused  of  making 
off  with  poultry— it  is  sometimes  called  "the  chicken  hawk"— the  red-toiled 
hawk  specializes  in  mice  and  other  creatures  harmful  to  crops. 

surface  are  surprisingly  evident.  The  red-tailed  hawk  is  of  medium 
size,  its  body  length  ranging  from  nineteen  to  twenty-five  inches. 
Its  wing-spread  may  be  fifty  inches  or  more.  The  Cooper's  hawk 
is  slightly  smaller.  It  looks  very  much  like  the  sharp-shinned 
hawk,  the  adult  males  of  both  species  having  blue-gray  plumage 
above  and  whitish  below  with  reddish-brown  cross  stripes. 

Many  hawks  perform  a  valuable  service  in  farm  areas  by  eating 
great  numbers  of  mice  and  other  destructive  small  mammals.  In 
spite  of  this,  there  is  a  popular  notion  that  all  hawks  are  the 
farmer's  enemies. 

"But  don't  chicken  hawks  steal  the  farmer's  hens?"  your  child 
may  ask. 


64  ]  The  Delightful  Hobby  of  Bird  Watching 

Strangely  enough,  it  is  not  the  chicken  hawks  that  do  the  steal- 
ing. Or  if  they  do,  it  is  an  exceptional  case.  The  two  kinds  widely 
known  as  chicken  or  hen  hawks  are  the  red-tailed  hawk  and  the 
red-shouldered  hawk.  Both  of  these  eat  mostly  mice,  gophers  and 
other  mammals,  insects,  and  reptiles.  Only  rarely  do  they  attack 
poultry. 

The  Cooper's  hawk,  however,  is  one  that  the  farmer  may 
definitely  class  as  bad  from  his  point  of  view.  The  sharp-shinned 
hawk  also  kills  chickens  as  well  as  many  wild  birds.  The  chances 
are  that  the  larger  and  more  strikingly  marked  red-shouldered 
and  red-tailed  types  attract  the  most  attention,  while  the  smaller 
and  less  noticeable  Cooper's  and  sharp-shinned  hawks  actually 
carry  out  the  sneak  attacks  on  poultry  yards.  So,  ironically  enough, 
birds  that  are  really  allies  of  the  farmer  are  classed  as  foes. 

Bald  Eagles 

"Is  the  bald  eagle  really  bald?" 

Inquisitive  children  ask  this  question  so  often  that  you  ought 
to  have  a  ready  answer  handy.  Actually  this  bird  has  a  fine  crop 
of  feathers  on  its  head;  but  because  they  are  white,  in  contrast  to 
most  of  its  plumage,  they  do  not  show  up  when  seen  from  a 
distance. 

Because  of  its  strength  and  daring  and  its  air  of  majestic  dignity, 
the  Americans  chose  the  bald  eagle  as  their  national  emblem  when 
they  first  formed  an  independent  nation.  Some  people  find  fault 
with  this  selection  on  the  ground  that  eagles  often  get  their  food 
by  snatching  it  from  terrified  smaller  birds  that  have  procured  it 
from  river,  lake,  or  ocean.  This  banditry  charge  is  true,  but  it  is 
difficult  to  watch  the  enormous-winged  creature  soaring  through 
the  air  without  thinking  of  it  as  a  noble  bird. 

The  golden  eagle  of  the  West  is  somewhat  larger  than  the  bald 
one  and  has  been  known  to  grow  as  long  as  forty-three  inches.  It 
has  sometimes  been  accused  of  carrying  off  children  in  its  enormous 
claws.  However,  there  is  apparently  no  verified  case  of  this  haj> 
pening,  and  experiment  has  shown  that  six  pounds  is  about  the 
greatest  weight  the  golden  eagle  can  carry. 


DUCKS  ARE  NATURAL 
COMEDIANS 

A  duck's  short  legs  are  placed 
tar  apart,  making  i^  walk  with 
an  amusing  waddle,  and  its 
voice  is  as  comical  as  it  is 
raucous.  No  wonder  that  this 
bird  inspired  the  universally 
popular  cartoon  character, 
Donald  Duck.  Water,  not 
land,  is  the  duck's  proper 
element,  and  in  a  pond  it 
swims   and    dives    expertly.

Vultures— Nature's  Street  Cleaners 

These  are  the  birds  that  actually  merit  the  name  "bald," 
as  the  head  and  neck  of  both  black  and  turkey  vultures  are  bare 
of  feathers.  When  you  see  one  of  these  birds  of  prey,  in  the  flesh 
or  in  pictures,  you  are  more  likely  to  be  repelled  than  attracted; 
no  one  is  apt  to  speak  fondly  of  a  vulture.  Nevertheless  it  is 
extremely  valuable  as  a  scavenger,  and  in  certain  towns  of  the 
South,  vultures  form  a  dependable  street-cleaning  department. 

Gulls— They  Roost  on  Water 

You  are  most  likely  to  see  gulls  along  the  seashore  and  in 
bays  and  harbors.  But,  as  many  of  them  nest  on  the  islands  of  inland 
lakes,  it  is  not  impossible  to  glimpse  them  in  a  wide  variety  of 
places.  The  herring  gull,  abundant  along  the  Atlantic  Coast,  is 
one  of  the  largest  types  and  has  a  gray  back  and  wings  that  are 
tipped  with  black.  The  California  gull  closely  resembles  the 
herring  gull.  Some  kinds,  such  as  the  laughing  gull  of  the  East 
and  the  Franklin  gull  of  the  West,  have  a  black  head. 

Gulls  are  as  buoyant  as  cork  on  the  water  and  they  often  rest 
and  roost  there.  They  are  a  valuable  aid  to  sanitation  along  water 
fronts,  especially  in  harbors  where  garbage  is  dumped.  They  often 
gather  in  tremendous  numbers  at  such  places  and  seize  the  refuse 
as  it  is  thrown  off  scows.  It  is  exciting  to  watch  them  vie  for  offal 
discarded  from  a  returning  fishing  craft  when  the  catch  is  being 
cleaned.  In  addition  they  devour  the  bodies  of  dead  creatures  of 
the  sea  which  have  floated  to  the  surface. 

Making  Wild  Birds  Feel  at  Home 

Rescuing  a  helpless  animal  is  one  of  childhood's  greatest  thrills. 
Most  youngsters  are  thoroughly  delighted  at  an  opportunity  to 
care  for  an  injured  older  bird— or  a  baby  bird  that  has  become 
separated  from  its  parents. 

This  is  an  endearing  trait  in  children,  but  before  you  let  them 
make  the  attempt,  you  ought  to  know  how  hard  it  is  to  feed  wild 
birds— especially  the  young  ones.  Baby  birds  often  starve  to  death 
because  people  have  no  conception  of  the  enormous  quantities  of 
food  the  fledglings  require.  These  figures  tell  the  story:  A  house

wren  was  seen  feeding  her  three  babies  1 1 1  spiders  and  insects 
within  four  hours!  Chipping  sparrows  brought  their  three  young- 
sters thirty-seven  grasshoppers  in  an  hour  and  a  half.  Most  amazing 
of  all,  a  baby  robin,  just  ready  to  leave  its  nest,  was  able  to  eat 
the  equivalent  of  fourteen  feet  of  earthworms  in  a  day! 

Fortunately,  you  can  supply  substitutes  for  natural  foods  if  a 
young  bird  suddenly  becomes  your  responsibility.  Sparrows,  rob- 
ins, bluebirds,  waxwings,  and  many  others,  will  flourish  on  a 
well-balanced  diet  of  meal  worms,  hard-boiled  egg  yolk  fully  grated, 
bread  with  milk,  and  berries. 

Remember,  before  rashly  adopting  a  bird  "orphan,"  that  young 
ones  sometimes  become  separated  temporarily  from  their  family 
and  cry  loudly  trying  to  attract  their  parents'  attention.  If  you 
find  one  of  these  lost  youngsters  on  the  ground,  you  do  best  to 
place  the  bird  gently  on  the  branch  of  a  tree  rather  than  take  it 
home.  If  the  hour  is  late,  your  wisest  course  may  be  to  take  the 
baby  home  and  wait  until  early  next  morning  to  return  it  to  the 
place  where  you  found  it. 


THE  RAVEN-FRIEND  OR  FOE? 

These  blackbirds,  immortalized  by  Edgar  Allan  Poe  in  his  famous  poem,  are  twice 
as  big  as  crows.  They  are  very  intelligent  and  can  be  trained  to  talk  and  to 
perform  simple  stunts.  But  out  in  the  fields,  ravens  are  a  nuisance  and  their 
raids  are  very  costly  to  farmers.  Their  notes  are  loud  and  coarse. 


The  Delightful  Hobby  of  Bird  Watching  [  67 

If  you  succeed  in  raising  a  young  bird,  you  will  want  to  give  it 
its  liberty  as  soon  as  it  is  able  to  shift  for  itself.  In  fact,  there  are 
many  species  which  cannot  be  legally  kept  in  captivity  without  a 
permit.  Crows  are  one  of  the  exceptions  to  this  ruling,  and  they 
may  become  fascinating  pets.  If  they  are  taken  as  young  birds, 
they  attach  themselves  firmly  to  a  household  and  shun  the  efforts 
of  other  crows  to  draw  them  away.  They  enjoy  the  companionship 
of  humans  and  can  learn  to  talk  like  parrots.  Unfortunately,  some 
people  mistakenly  believe  that  splitting  a  crow's  tongue  helps  it 
talk.  This  is  a  cruel  thing  to  do,  and  futile  as  well;  the  crow  does 
not  use  its  tongue  to  produce  sounds. 

You  will  find  tame  crows  at  a  number  of  zoos.  The  Philadelphia 
Zoo  used  to  keep  one  near  the  main  entrance,  where  it  would 
greet  arrivals  with  a  cheery  "Hello";  and  there  was  another  whose 
favorite  exclamation  was,  "Wowl  Cold  out!"  even  in  midsummer. 
A  crow  named  Deacon  was  one  of  the  first  features  of  the  Chil- 
dren's Zoo  at  the  Bronx  Zoological  Gardens  in  New  York  City. 
Someone  had  found  the  bird,  a  forlorn  little  orphan,  under  a  tree. 
The  crow  repaid  the  good  care  he  received  from  zoo  officials  by 
playing  the  gracious  host  to  countless  boys  and  girls. 

Like  crows,  some  owls  make  fine  pets.  An  elderly  friend  of 
mine  delights  in  reminiscing  about  a  great  horned  owl  he  had 
when  he  was  a  boy.  He  found  it  as  a  small  ball  of  down  under  a 
huge  nest  in  the  woods  near  his  home  and  immediately  became 
the  bird's  foster  father.  He  named  it  Jack  and  took  full  charge  of 
its  diet  of  raw  fish,  flesh,  and  fowl,  keeping  it  healthy  and  happy 
until  it  was  full-grown. 

"Jack  was  an  ajffectionate  bird,"  he  recalls.  "Often  he  would 
sit  beside  me  and  I  would  ruffle  his  feathers  just  behind  his 
head.  He  would  bend  forward,  his  eyes  almost  closed,  and  every 
few  minutes  there  would  be  a  succession  of  deep  baritone  hoots." 
Such  gentle,  trusting  companionship  can  mean  a  great  deal  to  a 
child.

osT  CHILDREN  who  livc  ill  Tural  areas  are 
accustomed  to  chickens,  ducks,  and  other 
domesticated  birds  as  part  of  the  daily  scene.  To  city  dwellers 
these  creatures  may  seem  even  more  remote  than  the  wild  birds, 
which  at  least  make  their  home  in  parks  of  metropolitan  areas. 
But  whether  farm  birds  are  intriguingly  distant  or  familiar  to  the 
point  of  being  commonplace,  they  repay  close  observation. 

We  think  of  chickens  as  being  very  timid,  in  fact,  "chicken- 
hearted."  Yet  they  become  exciting  personalities  when  two  roosters 
engage  in  a  duel.  The  two  antagonists  face  each  other  with  lowered 
heads,  then  each  strikes  out  with  his  wing  spurs,  tears  his  opponent 
with  his  leg  spurs,  and  tries  to  seize  him  by  the  back  of  the  neck 
with  his  beak.  Roosters  are  unbelievably  tenacious  fighters,  going 
after  each  other  with  brutal  abandon.  Though  roosters  fight  it  out 
for  barnyard  supremacy,  they  display  equal  spirit  against  rats, 
skunks,  hawks,  and  other  marauders. 

Chickens  have  a  varied  and  eloquent  language  all  their  own. 
The  rooster's  crow  is  unmistakably  boastful,  challenging.  When  a 
hen  is  setting,  she  sounds  irritable;  when  her  chicks  have  hatched, 
her  voice  takes  on  a  triumphant  note.  When  she  is  enjoying  the 
sun  in  the  company  of  other  hens,  she  sounds  pleasantly  chatty; 
when  frightened,  she  squalls.  Listening  to  these  notes  and  others 
as  well,  and  interpreting  them,  is  an  interesting  pastime  for 
youngsters.

Turkeys— The  Pilgrims'  Pride 

The  turkey  gobble  is  possibly  the  most  famous  of  all  bird 
sounds.  The  tom  "gobbles"  aggressively  as  he  struts  and  displays 
his  beauty  to  a  flock  of  hens.  He  lifts  his  beautiful  tail  feathers 
in  a  semicircular  fan,  sticks  out  his  breast,  and  makes  a  handsome 
ruff  by  raising  the  iridescent  plumage  about  his  neck. 

The  Bronze  Turkey:  There  is  a  bronze  breed  of  turkey  that  has  a 
very  close  resemblance  to  the  North  American  wild  turkey. 

From  its  neck  halfway  to  the  middle  of  its  back  the  plumage 
is  bronze,  glittering  with  green  and  purple  tones.  Each  feather 
is  tipped  with  a  narrow  black  band.  The  breast  plumage  is  the 
same.  As  for  the  lower  back,  it  is  black  except  for  a  bronze  edging 
on  each  feather.  The  long  quills  on  the  wings  are  crossed  with 
black-and-white  bands,  and  each  feather  of  the  fan-shaped  tail  is 
banded  with  black  and  brown  and  at  the  end  has  a  black  bar 
tipped  with  white. 

The  hen's  plumage  is  similar  in  color— except  that  her  breast, 
neck,  and  wings  are  not  so  brilliant,  being  dimmed  by  a  line  of 
white  at  the  tip  of  each  feather.  The  warty,  wrinkled  skin  over 
the  head  and  neck  of  both  sexes  is  colorful:  bluish  white  on  the 
crown,  grayish  blue  about  the  eyes,  and  the  rest  red.  In  the  male 
the  colors  are  more  vivid. 

Turkey  With  Trimmings:  Turkeys  have  several  distinctive  "trim- 
mings."  The  wattle  (as  in  chickens)  is  a  hanging  fold  below  the 
throat.  Above  the  beak  is  the  "caruncle,"  a  fleshy,  pointed  knob 
which  on  the  gobbler  is  long  enough  to  fall  over,  and  hang  below, 
the  beak.  When  the  bird  is  angry,  both  these  parts  swell  and  turn 
a  more  brilliant  red. 

On  all  toms,  and  occasionally  on  a  hen,  you  will  see  a  "beard"— a 
bunch  of  black  bristles  hanging  from  the  center  of  the  breast. 
These  hang  limply  when  the  birds  are  feeding,  but  when  a  gobbler 
struts,  he  thrusts  the  beard  forward. 

How  the  Turkey  Got  Its  Name:  Despite  the  Thanksgiving  lore 
absorbed  at  school— or  perhaps  because  of  it— your  youngster  may 
raise  this  point:   "Did  the  Pilgrims  have  to  go  out  and  shoot 


7©  ]  Birds  of  Farm  and  Zoo 

turkeys?  Didn't  they  raise  them  on  their  farms?" 

The  answer  is  rather  complex.  When  the  early  Spanish  explorers 
came  to  Mexico  they  discovered  a  breed  of  turkeys  with  white- 
tipped  tail  feathers  and  took  some  of  them  back  to  Europe.  About 
a  century  later,  the  Pilgrims  brought  domesticated  descendants  of 
these  turkeys  to  eastern  North  America.  There,  as  well  as  farther 
to  the  west,  turkeys  with  brown- tipped  feathers  were  to  be  found 
in  a  wild  state.  Thus  the  Pilgrims  had  the  white-tipped  turkeys 
in  captivity,  but  they  filled  their  larder  by  hunting  brown-tipped 
ones  as  well. 

Apparently  this  Western  bird  was  given  an  Oriental  name  in 
the  course  of  its  travels  from  continent  to  continent.  When  it 
first  appeared  in  Europe  it  was  confused  there  with  the  guinea 
cock,  an  African  bird  that  was  imported  by  way  of  the  Turkish 
dominions.  While  the  two  kinds  of  birds  were  later  distinguished 
from  each  other,  the  name  "turkey"  was  kept  for  the  American 
bird. 

The  Sun  Dance:  Turkeys,  wild  or  domesticated,  have  a  curious 
custom— a  "sun  dance."  While  dawn  is  still  faint  in  the  sky,  the 
birds  gather  and  begin  high-stepping  flip-flop  motions.  As  they 
jump  up  and  down  with  wings  lifted,  the  hens  call  quit,  quit, 
and  the  males  accompany  them  with  a  high-keyed  rattle.  No 
sooner  does  the  sun  show  above  the  horizon  than  the  dance  ends 
as  abruptly  as  it  began. 

Ducks,  Tame  and  Wild 

In  your  study  of  wild  bird  life  you  may  find  that  water 
birds  are  on  the  whole  less  accessible  than  land  birds.  The  duck 
is  an  excellent  representative  of  the  water  dwellers  that  you  can 
observe  at  close  range  by  visiting  a  barnyard.  When  you  see  a 
duck  on  shore  you  may  have  a  good  look  at  its  legs,  which  partly 
explain  its  prowess  in  the  water.  You  will  notice  that  the  duck's 
short  legs  are  set  wide  apart  and  far  back  on  its  body.  The  three 
front  toes  are  joined  by  a  tough  skin  or  web.  These  admirably 
adapted  legs  and  feet  make  perfect  paddles  in  the  water. 

Domesticated  ducks  have  modest  needs  in  the  way  of  shelter; 


Birds  of  Farm  and  Zoo  [71 

a  low  open  shed  to  protect  them  from  snow  and  driving  rains  is 
sufficient.  Their  thick  feathers  and  down  form  an  almost  weather- 
proof coat  which  shields  them  from  the  foulest  weather. 

The  Muscovy  Duck:  Ducks  are  raised  more  commonly  for  meat 
than  for  their  eggs,  though  some  breeds  are  good  egg  producers. 
There  are  ten  outstanding  varieties  of  ducks  that  are  widely  bred 
for  meat,  eggs,  or  both.  One  of  the  most  interesting  to  observe  is 
the  "Muscovy"  variety,  which  despite  its  name  is  native  to  Latin 
America.  It  cannot  quack  in  the  familiar  manner  of  most  ducks. 
Instead,  it  makes  a  hoarse,  raucous  hissing  sound;  and  it  has  the 
further  peculiarity  of  wagging  its  tail  from  side  to  side  like  a  dog. 
The  Muscovy  duck  is  a  better  flier  than  other  domestic  ducks,  and 
it  is  not  unusual  to  see  one  perched  on  top  of  a  barn.  Muscovys 
are  almost  completely  self-supporting.  They  make  their  own  nests, 
hatch  their  young,  and  raise  them  with  no  more  than  a  feed  of 
corn  once  or  twice  a  day. 

Fresh-Water  and  Salt-Water  Ducks:  As  the  ancestors  of  our  domes- 
tic breeds,  wild  ducks  are  among  the  better  known  of  bird  families. 
You  may  have  some  conflicting  stories  to  straighten  out  abou* 
them.  Your  boy  may  say: 

"Ducks  are  good  divers." 

His  pal  contradicts:  "I've  watched  them!  They  never  do  any- 
thing more  than  stick  their  heads  under  water  and  raise  their 
tails.  I  don't  call  that  diving." 

Actually  both  boys  may  be  right;  there  are  two  groups  or  sub- 
families of  ducks,  each  with  different  habits.  One  group  lives  in 
rivers  and  ponds,  the  other  in  bays  and  the  open  sea.  The  pond  and 
river  ducks  do  very  little  diving.  They  dabble  along  the  shore 
and  probe  down  into  the  mud  where  the  water  is  shallow.  The 
sea  ducks,  however,  are  expert  divers.  They  may  go  under  water 
150  feet  or  more! 

The  canvasback  is  probably  the  most  familiar  of  the  sea  ducks. 
One  of  the  best  known  of  the  river  and  pond  group  is  the  mallard. 
Many  varieties  of  domestic  ducks  are  descended  from  this  bird.

Geese— And  How  to  Know  Them 

"What's  the  difference  between  a  duck  and  a  goose?"  is  a 
question  that  might  readily  occur  to  any  boy  or  girl.  There  is 
much  about  either  animal  that  suggests  the  other,  and  it  is  true 
that  they  both  belong  to  the  same  bird  family.  Still,  a  duck  is  a 
duck  and  a  goose  is  a  goose!  The  goose  is  more  of  a  "landlubber" 
than  the  duck  and  feeds  more  on  land  vegetation.  Its  beak  is 
harder,  and  less  flat  in  appearance,  than  a  duck's.  The  legs  of  the 
goose  are  not  placed  so  far  back  on  its  body,  so  that  geese  are 
able  to  walk  and  run  more  freely  than  ducks. 

While  male  and  female  ducks  are  easily  distinguished  by  the 
usual  sex  difference  in  coloration,  geese  are  alike  in  color.  (The 
gander,  however,  is  larger  than  his  mate.  He  shares  the  responsi- 
bility of  incubating  the  eggs  and  helps  to  care  for  the  goslings.) 
Finally,  geese  usually  have  longer  necks  than  ducks.  All  these 
distinctions  add  up  to  a  difference  which  your  boy  or  girl  will 
easily  notice. 

Domestic  geese  have  largely  lost  their  power  of  flight,  but  in 
other  ways  they  suggest  their  wild  relatives.  They  honk  to  each 
other  in  expressive  goose  language.  Mother  and  father  bird  are 
devoted  to  each  other  and  to  their  young.  They  proudly  take  their 
goslings  to  the  pond  for  the  first  swimming  lesson  and  gently  push 
them  in  with  their  bills  if  they  hesitate. 

It  is  not  uncommon  for  a  wild  goose  that  has  been  injured  or 
become  overtired  to  join  a  domestic  flock  along  the  path  of  its 
flight.  But  usually  after  a  season  "the  call  of  the  wild"  is  so  strong 
that  it  will  join  any  flock  that  happens  along— unless  the  farmer 
has  clipped  its  wings. 

"Silly  Goose!":  Have  you  ever  called  your  child  a  "silly  goose"? 
This  widely  used  expression  is  strangely  inappropriate,  for  geese 
usually  seem  to  know  just  what  they  want  and  how  to  go  about 
getting  it.  Some  people  contend  that  geese  are  among  the  smartest 
of  all  animals. 

A  goose  named  Simon  who  lived  on  a  farm  I  often  visited  well 
deserved  this  reputation.  He  appointed  himself  guardian  of  the 
small  boy  of  the  family,  he  v/ould  take  no  nonsense  from  the  dog, 


Birds  of  Farm  and  Zoo 


[73 


and  he  "policed"  the  barnyard  in  such  a  way  that  we  liked  to 
imagine  him  in  a  cap  and  badge.  Even  the  adults  of  the  family 
hesitated  to  do  anything  out  of  the  ordinary  routine  for  fear  of 
provoking  Simon's  displeasure. 

Geese  react  resourcefully  under  danger.  A  goose  is  quick  to  dive 
under  water  if  it  is  wounded.  Then,  with  its  body  just  below  the 
surface  and  only  its  bill  exposed,  it  heads  for  shore  where  it  tries 
to  hide  among  the  brush  and  grass. 

Both  goose  and  gander  will  defy  a  suspected  enemy  by  opening 
the  mouth  and  hissing  violently.  Nor  is  this  loud  "talk"  a  bluff. 
A  gander  is  able  to  seize  many  smaller  adversaries  in  his  strong 
hard  bill  and  beat  them  to  death  with  his  wings. 

The  Canada  Goose:  There  are  several  species  of  wild  geese  on  the 
North  American  continent,  but  probably  none  are  more  widely 
known  than  the  Canada  goose.  At  one  season  or  another  this  bird 


THE  CANADA  GOOSE-ANYTHING  BUT  SIUY 

Most  observers  are  agreed  that  the  goose  fs  the  most  intelligent  of  all  our  domesti- 
cated birds.  The  Canada  goose  is  perhaps  the  most  famous  of  all  the  wild  varieties. 
It  is  greatly  admired  for  its  fabulous  long-distance  migrations  covering  thousands 
of  miles.  A  large  bird— about  three  feet  long— it  is  noted  for  its  loud  honks. 


74  ]  Birds  of  Farm  and  Zoo 

may  be  found  from  the  Atlantic  Ocean  to  the  Pacific,  and  from 
the  Gulf  of  Mexico  to  the  Arctic. 

In  the  northern  part  of  its  range,  when  the  days  grow  shorter 
and  a  hint  of  frost  warns  that  winter  is  approaching,  the  leaders  of 
the  flocks  spur  their  followers  to  action.  These  leaders  are  usually 
old  ganders  that  have  trekked  down  the  continent  and  back  many 
times. 

The  birds  soar  skyward.  High  above  the  ground  they  form  two 
lines  which  join  to  form  a  large  V,  with  the  lead-gander  at  the 
forward  point.  His  strength  enables  him  to  make  the  initial  break 
in  the  air  mass.  He  starts  off  with  spirited  honks  and  is  frequently 
answered  by  the  birds  behind  him  as  if  by  way  of  assurance  that 
"all's  well!" 

As  a  rule,  migrating  geese  rest  at  night.  As  sundown  approaches, 
the  leader  looks  for  a  suitable  lake  and  glides  down  to  it  in  a  long 
incline,  followed  by  the  flock.  However,  if  no  safe  landing  place 
is  found,  a  flock  of  Canada  geese  may  stay  in  the  air  for  more  than 
twenty-four  hours.  It  has  been  calculated  that  they  sometimes  fly 
a  thousand  miles  without  a  stop! 

The  Graceful  Swans 

The  swan  belongs  to  the  bird  family  that  includes  the  duck 
and  the  goose.  Swans  also  favor  the  V  formation  in  which  migrating 
flocks  travel.  Both  the  male  and  the  female  swan  are  noted  for  their 
lovely  white  plumage  and  their  tranquil  grace  in  the  water. 

In  olden  times  the  striking  beauty  of  the  swan  was  a  favorite 
theme  of  many  myths,  legends,  and  fairly  tales,  and  to  this  day 
every  child  is  familiar  with  the  classic  story  of  the  Ugly  Duckling. 
Anyone  who  has  ever  seen  a  swan  can  understand  its  hold  on  the 
imagination  of  noted  composers  and  masters  of  the  ballet.  The 
famous  ballerina  Pavlova,  who  scored  her  greatest  successes  in  a 
composition  called  The  Swan,  was  very  fond  of  swans  and  kept 
them  as  pets  for  many  years. 

Pigeons 

Their  Courtship  Antics:  While  watching  pigeons,  you  have  prob- 
ably wondered  at  their  occasionally  odd  antics.  Sometimes  you 


Birds  of  Farm  and  Zoo  [  75 

may  see  one  pecking  at  another  bird's  head  and  pushing  it  around 
for  apparently  no  reason  at  all.  But  there  is  a  reason,  and  a  com- 
pelling one:  The  "pusher"  is  a  cock  bird  and  the  "pushed"  is  a 
hen.  The  pecking  and  pushing  are  part  of  the  cock's  breeding 
display.  The  cock  coos  much  louder  than  the  hen,  and  while  he 
is  performing  his  courtship  dances  the  hen  usually  feigns  indif- 
ference and  walks  away  from  the  male  who  is  striving  so  hard  to 
make  an  impression. 

Where  Pigeons  Are  Found:  You  may  encounter  pigeons  on  farms 
or  in  city  parks.  They  have  adapted  themselves  so  successfully  to 
city  life  that  they  are  often  a  distinct  nuisance  in  cluttering  and 
soiling  buildings.  And  sometimes  their  cooing  outside  the  windows 
of  a  humdrum  business  office  can  take  on  a  weird  unearthly 
quality!  But  children  love  these  birds,  and  "feeding  the  pigeons" 
has  become  almost  a  national  sport. 

There  is  nothing  novel  about  this,  for  pigeons  have  been 
popular  domestic  birds  for  many  centuries:  There  were  pigeon 
fanciers  in  ancient  Rome.  All  our  present  domestic  varieties  have 
been  developed  from  the  rock  pigeon,  a  wild  species  found  in  many 
parts  of  Europe  and  Asia. 

There  are  vast  numbers  of  pigeons  in  America,  but  they  also 
dwell  in  all  parts  of  the  temperate  and  tropical  regions  of  the 
world,  existing  in  the  greatest  quantity  and  variety  in  the  Eastern 
Hemisphere,  particularly  in  the  Australian  and  Malayan  regions. 

The  Homing  Pigeon:  This  remarkable  variety  was  developed 
during  the  Middle  Ages,  when  there  was  a  lack  of  dependable 
means  of  communication.  A  warrior  or  traveler  would  take  several 
of  these  pigeons  when  setting  out  on  a  journey.  After  a  few  days' 
travel,  he  would  attach  a  letter  to  one  of  the  birds,  which  on  being 
released  would  fly  straight  back  to  his  family  at  home.  Later 
he  would  send  back  more  letters  with  the  other  birds.  Today, 
champion  homing  pigeons  can  fly  at  the  rate  of  almost  a  mile  a 
minute,  keeping  up  that  amazing  pace  for  several  hours!

THE  OSTRICH-OUTRUNS  A  HORSE,  BUT  CANNOT  FLY 

A  giant  with  small  wings  and  long  legs,  the  ostrich  con  dash  off  at  sixty  miles  an 
hour  at  the  first  sign  of  danger.  Twenty-five  miles  an  hour,  though,  is  nearer  to 
its  normal  rote  of  speed.  At  bay,  the  ostrich  lashes  out  with  its  legs  with  a  force 
that  can  break  a  man's  leg.

Ostriches— The  World's  Largest  Birds 

Even  when  birds  are  extremely  rare,  children  may  become 
acquainted  with  them  through  pictures  and  stories  or,  better  still, 
see  them  in  the  flesh  in  some  of  our  larger  zoos.  You  may  find  the 


Birds  of  Farm  and  Zoo  [  77 

great  bird  of  Africa,  the  ostrich,  in  many  zoos— though  not  all  of 
them  are  able  to  accommodate  very  large  or  rare  species. 

The  ostrich  is  the  largest  living  bird:  A  full-grown  male 
measures  about  eight  feet  from  its  toes  to  the  crown  of  its  head. 
Its  wings  are  so  small  in  relation  to  the  size  of  its  body  that  a  child 
readily  realizes  that  the  ostrich  is  a  flightless  bird.  But  nature 
has  compensated,  as  it  so  often  does  when  an  animal  has  some 
lack  or  defect,  by  developing  other  traits  which  help  in  survival. 
We  see  this  compensation  in  the  case  of  the  small-winged  ostrich; 
it  has  tremendously  powerful  legs  on  which  it  can  travel  as  much 
as  thirty  miles  an  hour. 

The  Huge  Ostrich  Egg:  In  keeping  with  its  size  the  ostrich  lays 
eggs  that  are  about  eighteen  times  larger  than  a  chicken's  egg. 
A  family  group  of  ostriches  is  made  up  of  a  cock  and  several  hens. 
The  hens  all  lay  their  eggs  in  one  large  depression  scooped  out 
of  the  sand.  One  of  the  hens  covers  the  eggs  during  the  day,  but 
the  father  takes  over  the  task  at  night. 

The  Maligned  Ostrich:  When  you  go  to  see  the  ostrich,  your  child 
is  almost  certain  to  ask  about  the  bird's  reputation  for  stupidity. 
The  ostrich  gets  this  reputation  because  of  the  widespread  notion 
that  it  believes  itself  hidden  when  it  sticks  its  head  in  the  sand. 
Though  this  story  is  well  entrenched  in  people's  minds,  it  is 
completely  false.  This  fable  is  probably  based  on  the  fact  that 
when  an  ostrich  chick  is  alarmed,  it  flops  to  the  ground  and  extends 
its  long  neck  flat  along  the  surface. 

Peacocks— Nature's  Gorgeous  Spectaclk 

Even  when  he  is  not  "displaying,"  the  peacock  is  a  handsome 
bird.  But  if  you  are  lucky  enough  to  catch  him  in  the  act  of 
courting,  you  can  see  one  of  the  most  beautiful  sights  of  the  bird 
world. 

The  male  and  female  may  be  walking  quietly  side  by  side  when 
suddenly  there  is  a  rattling  of  quills  as  the  male  shakes  out  the 
feathers  of  his  train.  With  a  few  stiff-legged  steps  he  puts  himself 
ahead  of  his  companion.  Then,  with  a  dramatic  sweep  of  the  long 
feathers  which  trail  behind  him,  he  wheels  in  front  of  her,  lifts 


78  ]  Birds  of  Farm  and  Zoo 

and  spreads  his  gorgeous  fan.  This  fan  is  not  made  of  his  true  tail 
feathers,  which  are  stiff  and  blackish  and  entirely  concealed.  The 
true  tail  feathers  support  the  fan  when  the  long  brilliant  feathers 
are  held  erect. 

This  unforgettable  performance  will  bring  home  to  your  child 
just  what  we  mean  when  we  say  that  somebody  "struts  like  a 
peacock."  Incidentally,  the  other  members  of  the  pheasant  family, 
to  which  the  peacock  belongs,  are  also  given  to  the  display  habit. 
All  the  males  are  noted  for  their  colorful  plumage  and  dazzling 
displays.  A  curious  final  detail:  the  voice  of  the  peacock  is  not  in 
keeping  with  its  appearance,  being  shrill  and  unpleasant. 

Penguins— Birds  That  Swim  But  Can't  Fly 

The  penguin  is  a  prime  favorite  with  children  because  of 
its  comical  and  ingratiating  appearance.  Penguins  are  paradoxical 
creatures:  though  they  cannot  fly,  they  are  accomplished  swimmers  1 
Aside  from  diving  into  the  water  to  catch  fish  for  food,  they  love 
to  swim  for  the  fun  of  it. 

Laying  Eggs  on  Ice:  The  largest  kind  of  penguin,  the  "emperor," 
has  an  average  weight  of  seventy  pounds.  Unlike  some  other  species, 
it  is  a  true  antarctic  bird.  The  female  lays  her  egg  on  ice;  then,  to 
prevent  its  freezing,  she  tucks  it  in  a  fold  of  skin  between  her  legs 
and  crouches  low  over  it.  The  male  has  a  similar  fold  of  skin,  and 
the  parents  take  turns  shielding  the  egg  so  that  it  never  comes  in 
contact  with  the  ice  long  enough  to  freeze. 

Where  Penguins  Live:  Most  of  us  have  the  impression  that  all 
penguins  are  native  to  the  ice  barriers  along  the  coast  of  Antarctica. 
There  are  sixteen  or  more  species  of  penguins,  and  it  is  true  that 
most  of  them  live  in  the  frozen  wastes  of  the  far  South.  However, 
some  penguins  live  near  the  tropical  belts,  with  one  species  actually 
at  the  equator,  on  the  Galdpagos  Islands. 

Storks  and  More  Storks 

You  may  see  at  the  zoo  a  grotesque-looking  bird  which,  accord- 
ing to  a  sign,  is  a  stork;  but  it  appears  quite  different  from  the 
storks  that  have  been  described  in  stories  and  fables  you  have  read. 


Birds  of  Farm  and  Zoo  [  79 

A  close  look  at  the  sign  may  then  reveal  you  are  looking  at  a  jabiru 
stork.  This  is  one  of  twenty  or  more  different  kinds  of  stork.  It 
stands  between  four  and  five  feet  in  height,  and  is  striking  in  ap- 
pearance because  its  white  plumage  forms  a  strong  contrast  to 
its  bare  head  and  neck,  which  are  black.  Its  homeland  is  South 
America.  To  Africa  belongs  another  type  of  stork— the  "shoebill," 
with  its  bill  as  prominent  as  its  name  suggests.  Exquisitely  soft 
''marabou'*  feathers  are  taken  from  the  marabou  stork  of  Africa 
and  India.  Oddly  enough,  it  is  among  the  ugliest  of  birds,  with 
its  head  bare  of  feathers  and  a  large  bare  pouch  hanging  from  its 
throat.  Also  found  in  Africa  and  Asia,  as  well  as  in  Europe,  are 
black  storks,  handsome  birds  with  red  legs  and  beak. 

The  "good  luck"  bird,  the  stork  associated  with  children  (Dutch 
children  for  many  generations  have  chanted  a  verse  to  this  stork 
asking  for  a  little  brother)  is  white.  In  Denmark,  Germany,  Hol- 
land, and  Turkey,  where  white  storks  breed,  people  eagerly  at- 
tempt to  persuade  them  to  settle  on  their  housetops.  It  is  an  old 
custom  for  the  Dutch  to  erect  large  wooden  boxes  or  platforms 
above  their  chimneys  as  a  nesting  site.  Once  a  nest  has  been  used 
by  a  pair  of  storks,  they  return  to  it  year  after  year.  They  repair 
it  by  adding  sticks  and  reeds,  and  after  a  number  of  seasons,  the 
nest  may  be  several  feet  high.  During  breeding  season  they  make 
a  loud  clapping  noise  with  their  beaks,  but  aside  from  this  they 
are  silent.  They  display  great  affection  for  their  babies;  and  the 
Hebrew  name,  chasidah,  given  this  stork,  signifies  * 'kindness" 
or  "mercy.** 

Canaries— Favorite  Pets 

The  companionship  of  one  of  these  cheerful  songsters  has 
been  a  boon  to  many  otherwise  lonely  people.  For  several  hundred 
years  canaries  have  been  the  most  popular  of  all  bird  pets.  Today 
we  have  about  fifty  different  domestic  kinds,  each  with  distinctive 
coloring  and  markings.  Aside  from  the  familiar  yellow  canaries, 
you  may  see  others  with  blue-gray,  white,  cinnamon-brown,  and 
a  number  of  other  tones. 

Keeping  a  caged  pet  makes  it  very  convenient  for  you  to  observe 


8o  ]  Birds  of  Farm  and  Zoo 

at  close  range  many  phases  which  are  common  to  both  domesticated 
and  wild  birds.  A  canary  begins  to  molt  about  the  middle  of  July 
and  continues  to  exchange  old  feathers  for  new  until  the  end  of 
summer.  If  the  bird  starts  losing  its  feathers  after  this  normal  molt, 
the  chances  are  that  it  is  being  subjected  to  cold  drafts  or  to 
extreme  variations  of  heat  and  cold. 

Where  Canaries  Come  From:  Originally  canaries  came  from  the 
Canary  Islands  off  the  west  coast  of  Africa.  (The  islands  in  turn 
get  their  name  from  the  Latin  word  can/5— "dog"— because  of  an 
unusual  breed  of  large  dogs.)  But  the  islands  stopped  exporting 
the  birds  many  years  ago,  and  canaries  are  bred  extensively  in 
America  and  Europe.  The  wild  canary's  upper  plumage  is  olive 
green;  its  breast  is  golden  yellow.  „. 

Singing  and  Sex  Differences:  The  canary's  popularity  is  based  on 
song  rather  than  looks.  There  are  many  variations  in  voice  quality 
and  type  of  song,  with  the  "roller"  canary  rated  as  the  outstanding 
songster  of  the  canary  family.  A  first-rate  roller  sings  from  ten  to 
fourteen  different  notes  in  connected  or  "rolling"  phrases,  per- 
forming with  his  beak  closed.  The  general  style  of  singing  is 
inherited,  but  the  breeder  trains  the  young  males  to  establish  their 
song  properly  by  exposing  them  to  the  influence  of  a  tutor  bird 
for  about  three  months. 

Male  canaries  are  the  leading  singers;  but  this  is  not  necessarily 
a  guide  to  the  sex  of  an  individual  bird,  as  some  females  also  sing. 
An  experienced  breeder  verifies  a  bird's  sex  by  holding  the  canary 
in  his  hand  and  gently  feeling  its  abdomen.  The  casual  observer 
can  be  guided  by  these  points:  The  male  is  usually  slightly  larger 
than  the  female;  its  head  is  somewhat  larger;  the  eye  is  not  only 
larger,  but  bolder  as  well;  and  the  male's  call  is  louder  and  more 
musical. 

Parrots— Masters  of  Mimicry 

The  parrot  has  a  very  special  appeal  for  us  because  of  its 
talking  ability,  which  bridges  the  gap  in  a  way  between  "dumb" 
animals  and  humans. 

Children  are  often  disappointed  when  they  realize  that  instead 


Birds  of  Farm  and  Zoo  [Si 

of  conversing  with  them,  the  parrot  is  merely  imitating  sounds, 
copying  words  or  laughter  as  it  might  mimic  a  bird  melody  if  it 
were  a  song  bird.  But  this  disappointment  may  be  softened  by 
the  discovery  that  the  parrot  is  exceptionally  intelligent  for  an 
animal.  (Do  you  remember  Long  John  Silver's  parrot  Captain 
Flint  in  Treasure  Island  with  his  repeated  cry  of  "Pieces  of  eightl 
Pieces  of  eight!"?)  A  favorite  method  of  teaching  a  parrot  is  to 
hide  from  its  view  and  repeat  several  words  frequently,  slowly, 
and  always  in  the  same  tone.  -^  - 

Members  of  the  Parrot  Family:  Parakeets,  which  are  related  to  the 
parrots,  vary  in  size— but  most  of  them  are  small,  some  no  larger 
than  a  sparrow.  Though  parakeets  can  also  learn  to  talk,  it  is  not 
so  easy  to  understand  them,  for  they  speak  very  rapidly  and  in 
high-pitched  voices.  Distinguishing  between  the  parrots  and  the 
parakeets  is  something  of  a  problem,  as  there  is  no  sharp  dividing 
line  between  the  two  groups.  All  of  them  are  birds  of  the  forest; 
they  are  poor  walkers  but  good  fliers  and  climbers;  all  eat  fruit 
and  seeds. 

Other  relatives  are  the  macaws  (largest  and  most  brightly 
colored  of  the  family) ,  cockatoos,  cockateels,  lories,  lorikeets, 
conures,  and  the  interestingly  named  lovebirds,  noted  for  their 
affectionate  nature.  The  Amazon  parrot  is  a  popular  cage  bird, 
es{>ecially  the  species  with  blue  markings  on  its  face.  It  is  a  very 
efficient  talker,  though  the  African  gray  parrot  is  considered  the 
champion  in  this  respect. 

How  Birds  Began 

Sometimes  children  are  even  more  fascinated  by  the  remote 
and  somewhat  mysterious  past  than  by  the  wonders  they  see 
around  them.  So,  do  not  be  surprised  if  your  air-minded  son  or 
daughter  turns  to  you  with  such  questions  as,  "When  did  birds 
start  to  fly?"  and,  "Why?" 

The  Flying  Reptiles 

Fortunately,  and  in  a  way  that  seems  almost  miraculous, 
scientists  have  looked  back  over  the  ages  and  reconstructed  an 
understandable  picture  of  life  as  it  went  on  long  before  history 


82  ]  Birds  of  Farm  and  Zoo 

was  recorded.  Let's  pretend  to  look  through  their  magic  spyglass 
at  the  world  that  existed  about  150  million  years  ago.  What  do 
we  see? 

Dinosaurs  of  many  shapes  and  sizes  are  wandering  over  the 
land,  crocodiles  are  swarming  in  the  rivers,  and  lizards  are  running 
over  dry,  sandy  stretches.  In  addition  to  these  weird  creatures  on 
the  surface  of  the  earth,  we  see  others  soaring  overhead;  but  they 
do  not  seem  to  be  flying  so  much  as  gliding. 

It  does  not  take  us  long  to  realize  that  these  air-borne  animals 
have  a  big  advantage  over  the  earth-bound  monsters,  for  they  can 
swoop  earthward,  seize  a  victim,  and  then  soar  up  to  a  perch  and 
devour  their  prey  at  leisure  without  danger  of  attack  from  enemies. 
As  we  look  closer,  we  see  that  these  strange  gliders  are  not  birds: 
They  have  no  feathers.  Aside  from  their  flying  powers,  they  are 
not  unlike  the  reptiles  on  the  ground. 

We  look  again.  This  time  we  see  another  flying  creature.  This 
one  has  feathers!  It  is  a  bird. 

The  Earliest  Known  Bird 

Most  boys  and  girls  take  delight  in  impressive-sounding, 
mouth-rolling  words,  and  your  child  will  enjoy  learning  the  name 
that  has  been  given  to  this  earliest  known  bird:  Archaeopteryx 
(arck-ee-op^-ter-ix) .  This  word  combines  two  Greek  terms  meaning 
"ancient  wing." 

Archaeopteryx  had  teeth  in  its  upper  and  lower  jaws  and  was 
equipped  with  a  long  tail.  It  was  its  feathers  that  took  it  out  of 
the  realm  of  reptiles.  In  time  the  teeth  were  to  disappear  and  the 
mouth  formation  was  to  change  until  it  became  a  hard  beak  more 
adapted  to  pecking  than  biting. 

Very  gradually,  over  a  long  period  of  time,  the  flying  reptiles 
disappeared  while  birds  grew  more  numerous  and  varied.  After 
Archaeopteryx  there  is  a  lapse  of  millions  of  years  in  the  known 
history  of  birds.  By  the  time  their  story  is  resumed  by  fossils  of 
a  much  later  age,  they  had  become  specialized  and  diverse:  They 
were  more  akin  to  modern  birds  than  to  Archaeopteryx.  Scientists 
believe  that  some  of  the  birds  that  enliven  our  earth  today  have 
existed  in  their  present  form  for  over  a  million  years. 


CHAPTER  OAnimals 

in  the  Wild 


A> 


DVENTURous  YOUNGSTERS  are  thrilled  at  the 
/  ^  thought  of  stalking  wild  animals.  It  may 
suggest  to  them  mighty  gorillas  hidden  in  trackless  jungles  or 
lions  prowling  over  African  plains— or  perhaps  a  man-eating  tiger 
that  is  terrorizing  a  village  in  India.  They  may  think  of  our  own 
North  American  deer  and  bears,  or  even  the  smaller  foxes  and 
wildcats. 

Though  the  animals  that  occur  to  them  may  be  of  many 
different  kinds,  one  thing  is  certain:  Each  will  be  four-legged  and 
have  fur  or  hair.  For  most  children— and  many  parents  as  well  I— 
only  this  type  of  beast  is  an  "animal." 

True,  these  beasts  are  animals,  but  they  are  only  one  type:  the 
mammals. 

Aside  from  mammals,  we  find  in  the  animal  world  many 
creatures  without  four  legs  and  fur.  Among  them  are  birds,  fish, 
snakes,  frogs,  spiders,  and  worms.  In  fact,  all  living  things  that  have 
feeling  and  the  power  of  voluntary  motion  may  properly  be 
termed  animals. 

"What  is  the  difference,  then,"  the  inquiring  young  mind 
wonders,  "between  mammals  and  other  kinds  of  animals?" 

To  be  considered  a  mammal,  an  animal  must  have  three  quali- 
ties. It  must  be  warm-blooded,  which  means  that  its  blood  remains 
at  nearly  the  same  temperature  no  matter  how  hot  or  cold  its 
surroundings  may  be.  It  must  have  hair  or  fur  on  its  body.  And  a 

83 


84  ]  Animals  in  the  Wild 

baby  mammal  is  always  nourished  by  milk  furnished  by  its  mother. 
Opportunities  to  observe  wild  mammal  life  at  first  hand  are  much 
less  common  than  those  for  bird  study.  At  an  early  age  children 
become  familiar,  to  be  sure,  with  a  variety  of  beasts  in  their  story 
books— the  bears  in  ''Goldilocks,'*  the  wolf  in  ''Red  Riding  Hood," 
the  fox  in  "Chicken  Little"— but  this  acquaintance  is  based  on 
fantasy  rather  than  facts.  When  the  youngster  begins  to  grow 
away  from  his  make-believe  world  and  shows  an  interest  in  animals 
as  they  really  are,  he  has  considerable  misinformation  to  discard 
as  well  as  facts  to  learn. 

Many  Kinds  of  Mammals 

A  useful  way  to  simplify  the  story  of  the  mammals  for  an  older 
child  is  to  group  these  animals  into  their  main  divisions. 

One  group  consists  of  flesh-eating  ("carnivorous")  mammals, 
such  as  wolves,  foxes,  lions,  and  tigers.  A  second  group  is  made 
up  of  rodents— mice,  squirrels,  beavers  and  others  with  long,  sharp 
front  teeth.  The  third  group,  the  hoofed  animals,  includes  deer 
and  cattle. 

Strange  water  mammals  known  as  manatees  and  dugongs  are 
in  a  class  by  themselves— so  are  the  flying  mammals  we  call  bats. 
Whales  are  probably  the  best  known  of  the  group  known  as 
"cetaceans." 

All  toothless  mammals  such  as  the  anteater  are  included  in  one 
group.  Finally  there  are  the  marsupials,  made  up  chiefly  of 
mammals  with  pouches  in  which  to  carry  their  babies.  The 
opossum  is  the  one  American  representative  of  this  group,  but  the 
kangaroo  of  Australia  is  perhaps  the  most  widely  known  of  the 
pouched  animals. 

Flesh  Eaters  and  Plant  Eaters 

On  the  basis  of  their  food  habits  mammals  may  be  divided  into 
two  general  classes.  There  are  plant  eaters  (herbivores)  and  flesh 
eaters  (carnivores) .  In  trying  to  distinguish  one  type  from  the 
other,  a  child  would  pretty  much  take  for  granted  that  the  flesh 
eaters  are  larger  and  stronger.  But  that  is  not  always  the  case. 


Animals  in  the  Wild 


[85 


Teeth  and  claws  are  a  better  basis  for  distinguishing  between  tne 
two  groups.  You  can  point  out  that  the  flesh  eater  has  sharp 
enlarged  canine  teeth,  shearing  side  teeth,  and  strong,  sharp  claws. 

*'Good"  and  "Bad"  Animals 

Perhaps  you  have  noticed  a  tendency  on  the  part  of  a 
young  child  to  label  certain  animals  "bad"  and  others  "good."  If 
you  query  the  child  you  are  likely  to  find  that  the  "bad"  animals 
are  those  which  eat  other  animals.  This  habit  may  well  be  frighten- 
ing to  a  child,  who  does  not  see  the  connection  between  his  own 
appetite  for  steak  and  the  needs  of  a  carnivorous  animal  devouring 
prey  in  order  to  sustain  life.  It  is  a  good  idea  to  point  out,  at 
some  appropriate  moment,  that  the  food  habits  of  both  flesh  eaters 
and  plant  eaters  are  inborn  and  not  a  matter  of  choice,  and  that 
moreover  the  flesh  eaters  seldom  kill  except  when  they  are  hungry 
or  defending  themselves  from  attack. 
Watch  a  dog  gnaw  a  bone  and  you  have  an  excellent  illustration 


THE  TIGER-FEROCIOUS  JUNGLE  PROWLER 

9n  the  zoo  the  tiger  looks  like  an  overgrown  pussycat;  in  fungle  regions  !t  is  a 
fierce  beast  of  prey.  When  attacking,  it  may  spring  fifteen  feet  or  more.  Its  stripes 
♦^re  a  useful  aid  in  stalking;  the  light-and-dark  pattern  blends  with  the  alternation 
ot  sunlight  and  shadow  in  the  jungle,  concealing  it  from  its  victims.

of  a  carnivorous  mammal  in  action.  Not  only  are  his  incisors  sharp 
and  the  canine  teeth  long  and  strong;  the  molars  are  especially 
designed  for  cutting. 

All  members  of  the  cat  family  are  meat  eaters.  Jaguars  and 
pumas,  the  largest  cat  animals  on  the  American  continent,  are  a 
menace  to  game  and  livestock  in  some  areas.  You  can  study  their 
hunting  tactics  at  close  range  when  you  watch  a  house  cat  stalking 
a  bird.  The  cat  does  not  run  down  its  prey  as  a  dog  would; 
instead  it  creeps  along  stealthily  until  it  is  within  striking  distance, 
when  it  takes  a  final  vicious  leap.  The  hunting  technique  of  the 
big  wild  cats  is  exactly  the  same. 

The  weasel  offers  solid  proof  that  you  cannot  judge  an  animal's 
eating  habits  or  its  disposition  by  its  size.  Though  small  and 
slender,  the  weasel  is  one  of  the  most  aggressive  and  ferocious 
of  flesh-eating  animals.  Completely  fearless,  it  sometimes  kills 
animals  several  times  larger  than  itself  and  may  satisfy  its  appetite 
merely  by  lapping  up  their  blood. 

Hunting  for  Animal  Tracks 

When  your  child  becomes  interested  in  the  activities  of  wild 
mammals,  you  can  join  him  in  a  fascinating  hobby:  hunting  for 
footprints  and  identifying  them.  In  bygone  days  the  Indians  were 
expert  trackers— but  for  them  it  was  not  a  hobby.  The  game  they 
secured  by  their  expert  knowledge  of  tracking  often  meant  the 
difference  between  starving  and  having  enough  food. 

Today  a  knowledge  of  animal  tracks  is  no  longer  necessary  for 
survival,  but  it  can  help  satisfy  the  child's  desire  to  play  nature 
detective.  What  child  is  not  thrilled  at  reviving  this  once- 
important  Indian  activity— especially  if  he  realizes  the  early  signifi- 
cance of  tracking! 

How  TO  Identify  Tracks 

You  may  start  track-hunting  by  going  to  likely  places  such 
as  muddy  stream  banks  and  finding  tracks  there,  identifying  them 
later— or  you  may  first  obtain  a  background  for  field  study  from 
books  and  observations  near  home.  In  your  own  back  yard  you 
may  find  the  tracks  of  dogs,  cats,  and  squirrels.

TRACKS  NEAR  HOME  AND  IN  THE  WILDS 

The  footprints  of  cots  and  dogs  are  excellent  ''first  studies"  in  tracking.  At  the  left 
are  the  tracks  of  a  domestic  cat;  next  to  them  are  the  tracks  of  a  lynx— similar  in 
form  but  more  than  twice  as  large.  The  tracks  at  the  far  right  of  the  drawing  are 
those  of  a  dog;  next  to  them  are  the  footprints  of  a  wolf.  It  is  almost  impossible 
to  distinguish  one  from  the  other,  except  for  size.  A  wolf  has  a  larger  foot  than  a 
dog  of  normal  size  (the  wolf  is  five  feet  long,  weighs  one  hundred  pounds). 


A  dog's  tracks  practically  duplicate  those  of  a  wolf  or  coyote 
except  that  the  wolf  tracks  are  usually  larger.  The  tracks  of  a  cat 
are  similar  to  those  of  the  wildcat  and  mountain  lion  except  for 
size.  In  these  tracks  only  the  pads  and  claws  make  an  imprint.

FLAT-FOOTED  ANIMALS  MAKE  THESE  TRACKS 

Tracks  made  by  an  animal  that  walks  on  its  toes  are  quite  different  from  these,  all 
of  which  show  the  soles  of  the  feet.  At  the  left  is  the  track  of  a  black  bear.  In  the 
center  are  footprints  made  by  a  running  raccoon.  At  the  right  are  tracks  of  a 
running  skunk.  Skunk  tracks  are  rare  in  winter— the  animal  hibernates  then. 

Bears,  skunks,  and  raccoons  make  plantigrade  tracks,  which 
means  that  they  are  practically  fiat-footed,  and  the  greater  part  of 
the  foot  shows  in  the  tracks.  Deer,  sheep,  moose,  and  elk  make 
hoofed  tracks. 

Another  clue  for  identification  is  that  tree-climbing  animals 
normally  place  their  front  feet  side  by  side  when  they  jump, 
whereas  animals  that  stay  on  the  ground  rarely  show  the  front 
feet  paired  in  this  way.  However,  the  hind  feet  of  both  tree- 
climbing  and  ground-living  animals  are  generally  paired. 

Raccoon  tracks  are  particularly  intriguing,  for  this  animal's 
hind  foot  is  long  with  a  well-marked  heel  and  five  comparatively 
short  toes  that  make  an  impression  remarkably  like  that  of  a 
small  human  foot.

Collecting  Tracks 

Children  are  eager  collectors.  If  they  wish  to  carry  their 
interest  in  tracking  still  further,  it  is  sometimes  possible  to  bring 
tracks  home— in  plaster.  Making  plaster  casts  of  tracks  is  not  a 
difficult  process.  Pamphlets  or  books  in  your  library  should  provide 
detailed  instructions  for  preparing  such  casts. 

There  are  other  ways  to  collect  tracks— photographing  them  or 
sketching  them.  Neither  you  nor  your  child  need  be  an  artist  to 
try  this;  a  very  simple  sketch  will  picture  a  footprint  quite 
graphically.

HOOFS  ARE  PLAINLY  INDICATED  IN  THESE  TRACKS 

At  the  left  are  footprints  of  the  whitetailed  deer,  such  as  you  might  discover  in 
summer  along  the  edge  of  small  ponds  or  lakes.  At  the  right  are  moose  tracks. 
Those  made  by  a  full-grown  moose  are  longer,  larger  and  more  pointed  than  those 
of  all  other  hoofed  animals.  Tracks  of  the  moose  are  not  uncommon  in  Maine.

FOOTPRINTS  IN  FIELDS  AND  NEAR  STREAMS 

Tracks  are  best  seen  after  a  light  fall  of  snow,  or  on  dry,  flat  ground  if  the  animal's 
feet  were  wet.  At  the  far  left  of  the  drawing  are  footprints  of  a  cottontail  rabbit. 
Nexi  to  them  you  see  the  imprint  made  by  a  bounding  gray  squirrel.  Next  is  the 
track  of  a  field  mouse,  and  at  the  for  right  is  the  trail  left  by  a  beaver.  It  Is  dis-

Tracks  can  reveal  exciting  incidents,  such  as  a  fox  over-

depict  peaceful  animals  wandering  in  search  of  shelter  and  food. 
After  a  fresh  snowfall  tracks  are  particularly  clear  and  easy  to 
follow. 

Sooner  or  later  tracks  lead  you  to  the  haunts  where  mammal 
parents  bring  up  their  young.  Altogether,  tracking  helps  furnish 
an  answer  to  your  child's  question:  "What  do  mammals  do?"  It 
becomes  apparent  that  securing  food  and  raising  families  are  their 
major  concern.  -  - 

How  Mammals  Talk 

Most  children  get  their  first  inklings  of  animal  communication 
when  they  become  familiar  with  the  sounds  made  by  dogs  or  cats. 
The  dog  barks  and  squeals  with  pleasure;  he  growls  when  he  is 
angry,  whines  when  he  is  afraid,  and  howls  for  the  sheer  pleasure 
of  hearing  his  own  voice. 


^^_.A.}^ 


THE  FEEBLE  CAU  OF  THE  MIGHTY  BULL  MOOSE 

Standing  about  six  feet  high  at  the  shoulder,  the  bull  moose  mokes  a  majestfc 
appearance  with  its  formidable  antlers.  (Some  of  nature's  most  fearsome  duels 
have  been  fought  with  these  antlers.)  Yet  the  bull  moose  cannot  produce  any- 
thing   more   impressive    in   the   way  of  sound   than    a    subdued,   coughing    grunt. 


92  ]  Animals  in  the  Wild 

The  cat  mews  in  friendly  conversational  tones;  it  purrs  with 
contentment  and  yowls  when  it  is  hurt,  it  howls  and  screams  in  a 
fight.  Its  love  serenade  is  shrill  and  agonizing— to  the  human  ear. 

The  mammals  of  our  forests  and  plains  come  near  to  duplicating 
some  of  these  sounds,  and  they  have  other  kinds  of  vocal  expression 
as  well.  Some  mammals  roar,  some  whistle,  some  scream,  some  yap, 
some  bleat,  others  are  virtually  silent. 

One  of  the  more  unusual  sounds  is  sufficiently  well  known  so 
that  even  children  hear  about  it.  This  is  the  call  of  the  moose. 
Many  hunters  practice  it  diligently  in  the  hope  of  luring  one  of 
these  massive  creatures  within  gun  range.  The  hunters  learn  to 
imitate  the  female,  whose  call  is  like  the  bawl  of  a  domestic  cow. 
The  bull  moose,  for  all  his  size  and  strength,  usually  emits  nothing 
more  than  a  feeble,  coughing  grunt. 

Cry  Danger! 

To  a  child  it  is  especially  touching  to  note  that  frequently 
the  calls  and  cries  of  wild  animals  serve  to  alert  their  family  to 
the  approach  of  danger.  When  the  marmot,  standing  like  a  sentinel 
at  a  lookout  post,  gives  his  shrill  warning  whistle,  not  only  the 
marmots  but  mountain  sheep  and  other  creatures  as  well  take 
cover.  A  bear,  a  wolf— or  a  man!— may  be  approaching. 

Shrill,  also,  is  the  whistle  of  the  marmot's  cousin,  the  woodchuck. 
With  more  abandon  than  good  sense,  it  whistles  and  grinds  its 
teeth  while  trying  to  escape  from  an  enemy.  Gray  squirrels  give 
the  alarm  with  a  kind  of  flat  rasping  bark  finally  prolonged  into 
a  whining  snarl. 

Even  the  customarily  silent  mammals  find  their  voices  when  they 
are  wounded.  The  scream  of  a  white-tailed  deer  struck  by  a  bullet 
can  be  heard  half  a  mile  away,  and  a  rabbit  often  gives  a  piercing 
squeal  when  hit.  But  mammals  do  not  always  depend  on  their 
voices  to  express  emotion.  The  cottontail  rabbit  thumps  the 
ground  with  a  hind  foot  when  he  senses  danger.  The  beaver  slaps 
the  water  with  its  tail.  As  for  deer  and  sheep,  they  stamp  with  a 
fore  foot  when  they  are  frightened. 

A  museum  staff  guide  has  often  proved  to  me  that  animal 
sounds  have  a  powerful  appeal  for  children.  As  he  takes  visitors 


Animals  in  the  Wild  [  93 

through  mammal  exhibition  halls,  he  demonstrates  the  cries  of 
the  appropriate  creatures  in  a  thoroughly  uninhibited  manner. 
These  calls  are  enjoyed  not  only  by  the  group  of  visitors  assigned 
to  him,  but  by  fascinated  children  who  seem  to  appear  from 
nowhere,  all  eager  to  hear  what  animals  sound  like. 

How  Mammals  Fight 

Warfare  in  the  animal  world  is  not  limited  to  sporadic  outbreaks 
when  some  creature  or  other  decides  to  attack  its  neighbors. 
Instead,  the  warfare  is  constant  and  unceasing.  The  need  for  food 
drives  the  meat  eaters  to  prey  on  other  animals,  and  there  seem  to 
be  a  few  that  kill  for  the  sake  of  killing.  Among  some  groups,  the 
males  fight  it  out  to  win  a  mate  or  establish  themselves  as  leader 
of  a  herd.  Among  the  most  dramatic  of  mammal  battles  are  those 
between  animals  that  wear  antlers  or  horns--such  as  moose,  deer, 
elk,  and  goats. 

A  Duel  Between  Moose 

The  instinct  of  boys  for  pounding  and  pummeling  each 
other  seems  mild  indeed  compared  to  a  clash  between  two  bull 
moose.  Hostilities  may  start  with  a  moose  striking  its  antlers 
against  small  trees  in  a  way  that  broadcasts  his  defiance  to  all 
within  hearing.  Another  male  rushes  out  to  accept  the  challenge— 
and  the  battle  is  on!  Heads  lowered,  the  two  giants  rush  at  each 
other.  The  impact  of  the  collision  may  knock  one  down;  if  he 
regains  his  footing,  they  charge  again. 

Each  moose  tries  to  stab  his  enemy  with  the  sharp  brow  tines 
that  are  the  vicious  part  of  the  antler.  The  wide  flattened  areas 
are  useful  for  defense  in  warding  off  blows.  Frequently  it  is  a 
fight  to  the  death  for  one  of  the  contenders.  Sometimes  the  ending 
is  tragic  for  both:  Their  antlers  may  become  so  firmly  locked 
together  that  they  are  powerless  to  move,  and  death  by  starvation 
is  their  fate. 

Special  Battle  Techniques 

Mountain  lions,  jaguars,  and  other  members  of  the  cat 
family  have  four  long  pointed  teeth  (canines)  as  weapons,  as  well 


94  ]  Animals  in  the  Wild 

as  sharp  claws  that  can  be  withdrawn  into  the  fleshy  foot  pads 
when  they  are  not  needed.  When  your  child  sees  a  fight  between 
two  tomcats  he  can  feel  that  he  has  witnessed  real  jungle  warfare; 
they  use  their  teeth  and  claws  in  the  same  way  as  the  big  cats. 

Squirrels,  woodchucks,  rats,  and  other  rodents  have  dependable 
weapons  in  their  chisel-like  front  teeth,  though  rabbits  rely  chiefly 
on  their  strong  hind  legs  with  which  they  can  kick  savagely.  When 
rabbits  fight,  each  one  tries  to  leap  on  top  of  his  opponent  and 
kick  downward.  A  deer  avoids  trouble  whenever  possible,  but  if 
it  is  cornered  it  defends  itself  by  striking  at  the  enemy  with  its 
front  hoofs.  The  bucks  also  fight  with  their  antlers. 

Horses,  burros,  and  some  other  hoofed  mammals  are  able  to 
kick  with  both  front  and  back  feet.  The  grizzly  bear  has  strong, 
sharp  teeth,  and  its  huge  front  paws  can  be  deadly  to  an  enemy. 

Not-So-Secret  Weapons 

Some  mammals  have  specialized  defensive  weapons.  The 
skunk  can  discharge  a  notoriously  evil-smelling  scent  that  over- 
powers the  enemy  with  nature's  poison  gas.  Foxes,  wolverines, 
weasels,  and  some  other  animals  have  scent  glands  more  or  less 
like  the  skunk's  and  use  odor  as  a  defense  weapon.  But  none  of 
these  scents  is  so  potent  as  that  of  the  black  and  white  "wood 
pussy." 

Porcupines,  like  the  skunk,  are  not  aggressive;  they  are  slow- 
moving  and  stupid.  Their  quills,  however,  are  splendid  equipment 
for  defense.  Trapped  by  an  enemy.  Porky  contracts  his  skin 
muscles,  causing  the  quills  to  stand  erect.  Then  he  bunches  himself 
up,  raises  his  tail,  flails  anything  within  reach,  and  drives  many 
of  his  barbs  into  the  flesh  of  his  opponents.  Contrary  to  popular 
belief,  the  porcupine  never  shoots  or  throws  his  quills. 

Keeping  a  Mammal  C3iart 

Man  has  constantly  expanded  his  knowledge  of  the  world 
around  him  by  keeping  records.  You  and  your  child  will  find 
your  interest  in  nature  stimulated  if  you  keep  records  of  your 
observations.  A  chart  of  personal  findings  on  mammals  has  many

THE  PORCUPINE'S  REARGUARD  AHACK 

Muggish  in  its  movements  and  reactions,  the  porcupine  is  nevertheless  no  easy 
prey  for  other  animals.  It  uses  its  quills  only  as  a  last  resort  and  does  not  shoot 
them,  but  attacks  by  a  backward  rush,  driving  them  deep  into  its  foe's 
flesh.  Estimated  number  of  quills  for  an  individual:  25,000! 

attractive  features.  It  is  quite  different  from  a  bird  calendar,  as 
the  four-footed  creatures  are  neither  so  numerous,  so  varied,  nor 
so  easily  seen  as  the  birds. 

You  may  arrange  your  chart  by  calendar  months  or  by  species 
of  mammals  seen,  but  in  either  case  you  will  want  to  record  the 
time  and  place  of  your  observations.  You  can  start  it  when  you 
take  country  walks  with  your  son  or  daughter  and  continue  it 
through  the  years  until  the  child  is  old  enough  to  jot  down  later 
discoveries. 

Motoring  in  Search  of  Mammals 

In  many  regions  you  can  carry  on  your  search  for  mammab 
quite  successfully  by  car.  In  fact,  where  small  children  are  involved, 
this  method  is  far  more  practical  than  hiking.  In  some  of  the 
national  parks,  or  in  places  where  roads  run  through  field  and 
forest,  you  may  observe  a  variety  of  mammals— especially  if  you 
drive  slowly  and  travel  either  in  the  morning  or  late  afternoon.

One  of  the  greatest  thrills  my  family  had  during  a  tour  of  the 
United  States  came  in  Zion  National  Park  in  Utah  when  a  bobcat 
bounded  across  the  highway.  The  animal  was  so  close  to  our  car 
that  only  a  quick  use  of  brakes  prevented  our  hitting  it.  Shortly 
afterward  we  learned  from  a  ranger-naturalist  that  though  bobcats 
were  fairly  numerous  in  the  park,  one  of  these  animals  is  not 
likely  to  be  seen  by  visitors  more  than  once  in  twenty  years. 

Vivid  Details 

You  need  not  limit  your  record  to  animals  actually  seen; 
you  can  also  include  evidences  of  them.  Have  you  seen  footprints 
of  deer?  Have  they  led  to  trees  scraped  by  antlers?  Have  you 
found  a  woodchuck's  hole,  the  burrowings  of  a  mole,  or  the  dug-up 
turf  and  smooth  incline  at  the  water's  edge  which  proclaims  an 
otter's  playground?  An  account  of  your  experiences  may  include 
pictures,  tracks,  or  tufts  of  hair— an  endless  variety  depending  on 
your  inclinations  and  opportunities.  Whatever  form  your  findings 
take,  they  become  a  continuously  enriched  account  of  your  aware- 
ness of  the  world  of  nature. 

How  Mammals  Survive  the  Winter 

The  rigors  of  cold  weather  and  the  scarcity  of  food  create 
hardships  for  mammals  in  wintertime.  However,  this  is  unlikely 
to  impress  us  as  much  as  the  plight  of  the  birds,  as  mammals  are 
so  little  in  evidence  all  year  round. 

One  of  the  few  mammals  that  we  are  likely  to  see  during  all 
four  seasons  is  the  gray  squirrel.  On  cold  winter  days  children 
can  appreciate  the  practical  value  as  well  as  the  beauty  of  this 
creature's  fur  coat.  He  may  often  be  seen  scampering  over  the 
snow;  only  on  the  most  frigid  days  does  he  curl  up  in  his  tree- 
trunk  nest  and  cover  himself  with  his  bushy  tail.  He  has  some 
food  tucked  away  and  hunts  industriously  for  more  whenever 
i4^eather  permits. 

Even  hardier  ihan  the  squirrel  is  the  cottontail  rabbit,  which 
has  no  cozy  retreat.  A  pile  of  brush  is  usually  the  only  protection 
he  seeks.  When  his  favorite  grass  is  no  longer  available,  he  nibbles

grain.  These  caches  ore  so  large  that  people  have  been  known   to  rob  them.

THE  DEER-TIMJD  CREATURE  OF  THE  WILD 

These  shy,  graceful,  and  swift-footed  animals  were  hunted  by  the  Indians  long 
before  the  white  man's  arrival  on  the  shores  of  America.  Despite  centuries  of 
intensive  hunting,  deer  are  probably  more  numerous  in  this  country  than  ever 
before,  thanks  to  the  protection  of  our  modern  gome  laws. 

the  tender  bark  of  small  trees  and  shrubs,  dead  leaves,  weeds,  and 
flower  stalks. 

White-tailed  deer  also  endure  rugged  times.  Their  winter  home 
is  a  reasonably  sheltered  area  in  a  woods.  A  group  of  a  dozen  or 
more  band  together  and  choose  a  suitable  spot— called  a  "yard"— 
for  their  headquarters.  From  this  home  they  make  paths  to  places 
where  they  can  find  food:  tender  bark  and  shrubs,  lichens,  acorns, 
and  moss,  for  which  they  dig  under  the  snow. 

Wild  Mammal  Neighbors 

Squirrels— Nature's  Acrobats 

Of  all  the  wild  four-footed  animals,  the  gray  squirrel  is 
probably  the  one  most  commonly  observed  by  children.  He  dwells 
in  wooded  regions,  and  also  in  city  parks  and  suburban  areas  as 


gS  ]  Animals  in  the  Wild 

well.  In  fact,  these  attractive  rodents  seem  to  prefer  the  hazards 
of  civilization  to  the  dangers  of  the  wilds,  and  their  habits  vary 
little  whether  they  live  in  town  or  country. 

Young  Squirrels:  Watch  for  young  squirrels  about  the  middle  of 
May.  A  mother  bears  four  to  six  infants  during  March,  and  she 
may  have  a  second  litter  during  the  summer.  She  gives  her  young 
devoted  care.  They  are  born  blind  and  hairless.  When  they  are 
about  six  weeks  old  they  begin  to  climb  around  the  tree  branches 
and  nibble  at  buds  and  leaves.  At  eight  or  nine  weeks  they  have 
a  full  coat  of  fur  and  are  about  half  grown. 

In  a  year  they  have  almost  reached  full  growth  and  are  able  to 
leap  among  the  branches  with  astounding  agility.  The  bushy  tail 
is  a  great  help  in  balancing  and  making  easy  landings  possible. 
There  is  endless  entertainment  in  watching  the  acrobatics  of  a 
gray  squirrel.  I  recall  observing  one  of  them  leap  from  a  branch  of 
a  tree  to  a  long  attached  wire,  and  then  slide  down  the  wire  like 
a  fireman  using  his  pole  for  speedy  descent.  The  lure  was  a 
well-stocked  bird-feeding  station  at  the   end  of  the  wire! 

During  cold  weather  squirrels  generally  live  in  a  hollow  tree, 
but  later  in  the  year  they  find  a  suitable  location,  usually  thirty 
feet  from  the  ground  in  the  crotch  of  a  tree,  and  there  they 
construct  a  nest  of  dead  leaves  and  sticks.  The  shape  of  the  nest  is 
a  clue  to  the  tenant's  identity.  A  bird's  nest  is  flattened  at  the  top; 
the  squirrel's  is  rounded.  Red  squirrels  also  build  nests— sprawling 
but  comfortable  ones  of  bark,  twigs,  leaves  or  moss. 

Squirrels  and  Food:  As  you  watch  a  squirrel  bury  a  nut  in  the 
ground,  you  may  well  ask  yourself:  Will  he  ever  find  it  again?  It 
would  be  a  mistake  to  think  that  all  the  nuts  that  are  buried  get 
dug  up  afterward.  This  is  especially  true  in  the  wilds  where  food 
is  plentiful;  and  for  this  reason  the  squirrel  makes  a  valuable 
contribution  to  replanting  the  forests. 

However,  in  regions  where  winter  food  is  scarce  the  clever 
little  rodent  recovers  more  of  the  stored  nuts.  It  is  believed  that 
the  squirrel  is  guided  to  the  right  locality  by  memory,  and  to  the 
exact  spot  by  a  keen  sense  of  smell  which  can  penetrate  through 
several  inches  of  snow 


Animals  in  the  Wild  [  99 

Aside  from  nuts,  squirrels  enjoy  the  seeds  from  apples,  pears, 
and  other  fruit,  mushrooms,  corn,  and  wheat.  Sometimes  they 
raid  birds'  nests  for  eggs  or  fledglings,  though  they  are  guilty  of 
such  raids  less  often  than  red  squirrels.  An  overabundance  of 
peanuts  is  unhealthy  for  squirrels,  but  a  few  added  to  tree  nuts 
or  other  foods  are  a  nourishing  addition  to  their  diet. 

Rabbits— Nature's  Indestructibles 

If  you  are  familiar  with  the  story  of  Peter  Rabbit's  adven- 
tures in  Mr.  McGregor's  garden  you  have  an  excellent  basis  for 
understanding  this  rodent's  fate  in  life.  He  is  the  Pursued;  his 
daily  routine  is  one  escape  after  another.  In  addition  to  being  a 
victim  of  almost  every  flesh-eating  mammal  and  bird,  he  is  also 
a  favorite  target  for  sportsmen. 

How  Rabbits  Survive:  Yet  although  they  are  the  prey  of  countless 
enemies,  rabbits  are  fast  breeders  and  continue  to  exist  in  great 
numbers.  As  we  observe  them  we  see  two  further  features  which 
help  account  for  their  survival:  the  long  ears  that  detect  the 
enemy's  approach  from  a  distance,  and  the  long,  muscular  hind 
legs  which  propel  a  rabbit  away  from  danger  with  remarkable 
speed. 

A  further  aid  to  the  rabbit's  flair  for  self-preservation  is  its 
extremely  keen  sense  of  smell:  Its  nostrils  twitch  constantly  to 
catch  every  scent  in  the  air.  The  rabbit's  whiskers  serve  as  trusted 
feelers,  its  eyes  are  large  and  bright.  It  has  strong  front  cutting 
teeth,  and  with  its  split  upper  lip  makes  most  efficient  use  of  them. 

In  summer,  the  rabbit's  fondness  for  cabbage  and  lettuce  makes 
it  the  plague  of  gardeners.  It  also  feeds  on  grass,  clover,  and  other 
herbs.  During  the  winter,  when  green  leaves  are  scarce,  it  gnaws 
bark  from  trees  and  nibbles  buds  from  shrubs. 

There  are  many  varieties  of  rabbits.  Aside  from  those  living  in 
the  wild  state,  there  are  others  raised  by  thousands  of  people 
either  for  a  hobby  or  for  extra  income.  I  once  knew  a  rabbit  that 
began  its  career  as  an  Easter  pet.  Later  on  its  young  owner  kept 
it  at  his  family's  store,  where  the  rabbit  was  trained  to  snip  with 
its  front  teeth  the  cord  used  to  tie  packages.  This  novel  perform- 
ance stimulated  business  considerably!

TWENTY  FEET  AT  A  BOUND 

Jack  rabbits  are  among  the  swiftest  animals  in  creation.  They  may  hit  forty-five 
miles  an  hour  in  escaping  from  attack,  and  single  bounds  of  twenty  feet  are 
not  uncommon!  The  jock  rabbit's  long  ears,  reminding  us  of  those  of  a  jackass, 
inspired   its   popular   name.   They  ore   capable   of  extraordinarily   keen    hearing. 


Rabbits  and  Hares:  It  is  sometimes  confusing,  especially  to  a  child, 
to  hear  a  rabbit  called  a  hare.  Ostensibly  "hare"  is  just  another 
word  for  "rabbit."  Yet  actually  this  is  not  the  case.  Rabbits 
resemble  hares  in  appearance,  though  they  differ  in  some  of  their 
habits.  Hares  are  larger  in  size. 

Rabbits  are  bom  blind  and  hairless  and  completely  dependent 
on  their  mother's  care.  She  pulls  fur  from  her  own  body  with  her 
teeth  and  paws  to  line  the  nest.  When  she  goes  foraging  for  food 
she  covers  the  young  with  fur  and  grass.  This  serves  as  a  blanket 
and  also  as  camouflage.  Our  tame  rabbits  are  all  descendants  of 
wild  rabbits  of  Europe. 

The  babies  of  the  hare  are  born  with  their  eyes  open  and  are 
able  to  take  care  of  themselves  in  three  weeks  or  less.  The  jack 
rabbit  is  a  hare,  despite  its  common  name,  which  is  derived  from 
its  long  jackass-like  ears.  Its  shoulder  height  is  as  much  as  twelve 
inches  and  it  can  make  leaps  of  from  twelve  to  twenty  feet  with 
its  long  powerful  hind  legs.

Mice  and  Rats— Pets  and  Pests 

Among  parents  and  children  there  are  two  schools  of 
thought  about  mice.  As  far  as  the  adult  is  concerned,  these  rodents 
are  pests  to  be  exterminated  whenever  possible.  As  the  child  sees 
it,  mice  are  engaging,  clever  pets  that  can  be  kept  without  entailing 
a  great  amount  of  work  for  their  owner. 

The  House  Mouse:  The  house  mouse,  originally  a  native  o£  Asia, 
is  responsible  for  much  of  the  dislike  visited  on  the  whole  tribe. 
Through  its  ability  to  stow  away  wherever  food  is  kept,  this 
creature  infiltrated  into  Europe  and  later  on  came  to  this  country. 
Although  this  mouse  usually  makes  its  home  in  houses  or  bams, 
it  sometimes  nests  under  cornstalks  or  in  grain  fields. 

Indoors  it  uses  the  space  between  plaster  and  outer  walls  for 
runways,  or  else  it  travels  between  ceiling  and  floor.  With  its 
strong  gnawing  teeth  it  can  easily  cut  through  wood,  cardboard, 
or  almost  any  obstacle  but  metal.  The  mother  mouse  makes  her 
nest  out  of  cloth,  paper,  or  whatever  pliable  material  she  can  find. 

The  Harvest  Mouse:  Wandering  across  country  fields  you  may 
catch  sight  of  a  mouse  which  resembles  the  house  mouse  so  closely 
that  you  might  think  it  was  the  same  creature.  However,  the 
outdoor  species  is  probably  a  harvest  mouse,  content  to  find  its 
food  under  natural  conditions.  It  works  the  year  round  for  its 
living,  seeking  in  summertime  greens,  fruits,  berries,  and  a  variety 
of  seeds.  It  stores  some  seeds  in  its  nest  or  underground,  and  in 
the  winter  it  tunnels  under  the  snow,  if  need  be,  to  its  hidden 
supplies. 

Other  Members  of  the  Mouse  Family:  If  you  part  the  grass  in  the 
fields  and  find  hard-packed  little  roadways  about  an  inch  wide, 
you  have  probably  come  upon  the  meadow  mouse's  * 'communica- 
tion system"  between  burrows.  Again,  in  wintertime,  the  tiny 
animal  footprints  you  find  in  the  snow  often  prove  to  be  those  of 
the  meadow  mouse. 

The  most  attractive  and  interesting  of  wild  mice  is  the  white- 
footed  or  deer  mouse.  Look  for  it  in  the  woods  where  a  log,  a 
broken  rock,  or  merely  grass  provides  its  shelter.  It  is  an  excellent

THE  WHITE-FOOTED  MOUSE 

More  attractive  than  many  other  members  of  its  family,  the  white-footed  mouse 
is  an  appealing  creature  with  a  strong  bump  of  curiosity.  This  mischievous  little 
mouse  lives  in  the  woods,  and  eats  berries  and  nuts.  It  has  a  musical  voice  and 
often  chirps.  It's  a  native  animal,  unlike  the  house  mouse,  which  came  to  this 
country  at  about  the  time  of  the  American  Revolution. 


climber  and  occasionally  makes  its  home  in  a  bird's  nest  that 
has  been  deserted. 

Beavers— Sociable  Builders 

In  many  areas  where  it  was  once  threatened  with  extinc- 
tion the  beaver,  now  protected  by  law,  again  enlivens  the  land- 
scape. When  you  are  in  the  vicinity  of  beaver  homes  you  can  play 
a  game  that  never  fails  to  arouse  youthful  enthusiasm  in  nature 
exploring: 

"Who  will  find  one  first?" 

Competition  ends  when  you  or  your  young  companion  catch 
sight  of  a  beaver  home— a  rounded  mass  of  sticks  and  mud  rising 
like  a  miniature  island  out  of  a  lake.  This  is  where  a  beaver  family 
livesl

The  Beaver's  Home:  You  can  see  the  exterior  of  a  beaver  lodge 
and  admire  the  structure  of  the  dams  they  build  to  cause  water 
to  flood  around  it;  but  you  cannot  investigate  the  interior. 

If  you  could  look  inside  you  would  see  that  the  home  is  made 
up  of  one  large  room  or  several  smaller  ones.  In  either  case  you 
would  notice  openings  in  the  floor.  The  beaver  comes  and  goes 
through  these,  reaching  land  by  an  underwater  route.  As  the 
areas  in  the  lodge  around  the  floor  openings  are  wet  and  cold, 
the  main  floor  is  slightly  raised,  somewhat  like  a  step.  The  sleep- 
ing quarters  are  snugly  lined  with  wood  fibers,  chewed  fine,  or 
with  grass.  In  wintertime  the  mud  plaster  of  the  lodge  freezes, 
and  the  walls  become  so  strong  that  even  a  bear  cannot  break 
through. 

The  Beaver's  Building  Methods:  A  popular  myth  about  the  beaver's 
building  technique  is  that  he  uses  his  large  flat-ribbed  tail  as  a 


THE  EAGER  BEAVER 

Beavers'  work  is  never  done.  They  are  forever  gnawing  trees  into  neat  lengths, 
building  canals  for  floating  their  logs,  assembling  tons  of  material  for  constructing 
dams,  or  else  putting  together  one  of  their  snug  housing  developments,  complete 
with    a    hole    on   top    for   ventilation.    Mostly,    beavers    do    their   work    at    night. 


104]  Animals  in  the  Wild 

trowel  to  pat  down  mud.  Actually  he  works  with  his  fore  feet— some- 
times with  the  side  of  his  head— to  push  and  poke  mud  into  place. 
Another  belief  about  beavers  is  that  they  use  their  tails  as  "trailers" 
to  convey  grass,  earth,  and  stones  to  the  building  site;  but  such 
claims  have  always  lacked  proof. 

We  do  know  that  beavers  carry  these  materials  in  their  front 
paws  or  in  the  mouth.  The  tail  does  seem  to  be  useful  in  helping 
a  beaver  steer  and  propel  its  body  in  the  water.  Another  use  for 
the  tail,  as  we  have  learned,  is  that  by  slapping  it  against  the 
surface  of  the  water  the  beaver  is  able  to  warn  his  companions 
of  approaching  danger. 

The  Sociable  Beaver:  Beavers  form  sociable  family  circles.  They 
enjoy  being  together,  and  when  a  family  outgrows  its  lodge  they 
may  construct  new  homes  along  nearby  shores  until  a  large  settle- 
ment develops.  If,  on  the  other  hand,  overpopulation  results  in  a 
food  shortage  in  the  immediate  neighborhood,  the  generation  of 
two-year-olds  starts  off  in  search  of  a  building  site  for  a  new  colony. 
When  young  beavers  are  not  occupied  learning  the  serious  busi- 
ness of  tree-cutting,  engineering,  and  building,  they  like  to  play 
and  frolic,  sometimes  getting  underfoot  while  the  adults  are  at 
work. 

MusKRATS  Are  Also  Builders 

Muskrats  also  use  mud  in  building  their  homes,  but  they 
mix  it  with  roots  and  stems  of  plants,  for  they  live  in  marshes  and 
shallow  water  areas.  Beginning  the  construction  of  a  lodge  in 
shallow  water,  they  pile  layer  upon  layer  of  rushes  and  mud  until 
the  heap  is  large  and  reaches  a  height  of  four  or  five  feet  above 
the  surface  of  the  water.  Then  the  muskrat,  working  under  water, 
chews  and  digs  into  this  stack  from  the  bottom,  until  he  hollows 
out  a  space  above  the  water  line  large  enough  to  house  himself  and 
his  family. 

Near  towns  and  villages  you  are  much  more  likely  to  run  across 
muskrat  homes  rather  than  beaver  lodges.  Muskrats  seem  to  be 
undisturbed  by  the  sights  and  sounds  of  civilization,  whereas  the 
more  retiring  beaver  prefers  wilder  regions.  Muskrats  make  use 
of  swamps  and  streams  as  nature  provides  them,  and  they  also  take 


Animals  in  the  Wild  [  105 

advantage  of  man-made  ponds.  Despite  their  ingenuity,  however, 
they  have  never  learned  to  construct  their  own  dams,  as  beavers  do. 

Otters— Shy  But  Likable 

Few  creatures  are  as  wary  of  man  as  the  otter.  Even  when 
your  nature  trails  extend  far  beyond  cities  and  town,  you  may 
fail  to  catch  a  glimpse  of  this  attractive  animal.  But  though  otters 
remain  unseen,  you  can  still  find  evidence  of  their  whereabouts 
by  looking  closely  along  the  banks  of  streams  and  lakes.  There 
will  be  footprints  in  the  mud  that  borders  their  favorite  fishing 
waters. 

Otters  Outswim  Fish:  Otters  are  remarkably  swift  and  agile  in 
the  water:  They  catch  the  fish  they  delight  to  eat,  literally  out- 
swimming  theml  Yet  young  otters  are  anything  but  "born  swim- 
mers." They  live  quietly  at  first,  feeding  on  their  mother's  milk. 
When  they  are  old  enough  she  takes  them  for  their  first  swimming 
lesson.  By  way  of  encouraging  a  baby  she  has  it  climb  on  her 
shoulders;  then  she  dives  into  the  water,  often  swimming  with  the 
baby  still  clinging  to  her.  Lessons  may  continue  throughout  the 
summer  until  the  young  otters  are  as  big  as  cats.  Painstaking 
practice  finally  turns  the  pupils  into  first-class  swimmers. 

The  Otters'  Playful  Habits:  An  otter  family  keeps  together  for  at 
least  a  year,  and  all  its  members,  parents  as  well  as  youngsters, 
know  how  to  have  fun  the  way  boys  and  girls  do.  A  pastime  the 
otters  favor,  for  example,  is  for  two  of  them  to  pull  at  opposite 
ends  of  a  stick,  tug-of-war  fashion.  They  romp  and  roll  like 
puppies,  clawing  up  the  turf  and  throwing  the  clods  about.  Their 
greatest  fun  comes  from  sliding.  They  love  to  chute-the-chute  on 
their  stomachs  down  steep  river  banks  into  the  water,  and  will 
keep  this  up  in  one  place  until  it  becomes  very  slippery.  In 
wintertime  they  toboggan  down  snow-covered  hills. 

Moles— Nature's  Excavators 

You  do  not  have  to  go  far  afield  for  evidence  of  moles.  All 
too  often  unsightly  ridges  appear  in  your  garden  or  lawn  which 
proclaim  that  these  strange,  near-blind  underground  mammals 


io6  ]  Animals  in  the  Wild 

have  been  tunneling  there.  But  though  they  live  near  human 
dwellings,  moles  are  seldom  seen.  This  endows  them  with  a  rather 
mysterious  quality  for  a  child,  who  quite  naturally  wonders  how 
an  animal  can  dig  up  the  ground  while  it  is  actually  under  it. 

How  the  Mole  Burrows:  When  the  mole  is  digging,  it  braces 
itself  with  one  of  its  short  powerful  front  paws  while  the  other 
pushes  the  soil  upward— this  is  how  the  ridges  that  disfigure 
your  lawn  are  created.  To  make  deeper  tunnels,  the  mole  scoops 
the  earth  under  its  body  and  pushes  it  as  far  back  as  possible  with 
its  back  feet.  Every  now  and  then  the  mole  turns  a  somersault  and 
then  proceeds  in  the  opposite  direction,  shoving  the  accumulated 
pile  of  dirt  along  until  it  comes  to  a  vertical  tunnel  excavated  on  a 
previous  occasion.  Here  the  mole  forces  the  dirt  up  into  the  open, 
forming  the  proverbial  "molehill." 

The  mole's  nest,  lined  with  grass  and  leaves,  is  some  six  to 
twelve  inches  below  the  surface  of  the  ground.  A  main  passageway 
leads  from  the  nest  to  a  series  of  tunnels  extending  in  all  direc- 
tions. Most  of  these  tunnels  lead  in  turn  to  hunting  grounds 
where  worms  and  grubs  abound;  but  one  tunnel  is  reserved  for  an 
emergency  exit  when  danger  threatens. 

Prairie  Dogs— Master  Engineers 

The  chubby  rodents  known  as  prairie  dogs— they  were  mis- 
named by  early  pioneers  in  the  plains  region— are  also  remarkable 
excavators.  We  do  not  have  a  clear  picture  of  just  how  they  carry 
out  their  elaborate  digging  operations,  but  we  know  that  each 
prairie  dog  family  has  a  burrow  of  its  own  consisting  of  a  main 
shaft  which  goes  straight  down  about  fourteen  feet.  Horizontal 
tunnels  branch  out  from  the  shaft  to  the  animals'  sleeping  quarters. 
Other  vertical  shafts  rise  from  some  of  the  horizontal  tunnels 
and  are  probably  used  as  safety  zones  in  case  the  lower  levels  are 
flooded.  The  burrows  are  grouped  together  in  large  colonies, 
sometimes  called  "towns."  There  is  reason  to  believe  that  some  of 
these  towns  once  had  a  million  or  more  inhabitants! 

Tall  Tales:  Many  fantastic  stories  have  been  told  about  a  cozy 
alliance  between  prairie  dogs,  burrowing  owls,  and  rattlesnakes 


Animals  in  the  Wild  [107 

for  sharing  the  same  burrows  in  friendly  fashion.  It  is  true  that 
these  mammals,  birds,  and  reptiles  do  inhabit  the  same  western 
regions;  but  that  is  all  there  is  to  the  alliance.  The  owls  dig  holes 
for  themselves— though  they  may  put  a  prairie  dog's  burrow  to 
use  under  favorable  circumstances;  and  a  rattlesnake  may  occupy 
the  burrow  of  either  animal.  It  is  a  most  unwelcome  intrusion, 
however,  probably  resulting  in  the  loss  of  the  young  of  the  rightful 
home  owners.  — 

The  Wary  Marmot 

Prairie  dogs  are  related  to  the  golden-mantled  marmots 
which  are  so  numerous  in  some  of  our  western  national  parks— 
where  they  have  lost  much  of  their  fear  of  people.  Even  so,  you 
may  see  a  group  eating  while  one  animal  stands  guard.  Whenever 
this  lookout  senses  danger  it  gives  a  single  sharp  whistle  and  all 
scurry  for  cover.  Nevertheless,  marmots  combine  some  curiosity 
with  their  caution,  and  if  you  are  able  to  give  a  near-imitation  of 
their  whistle,  you  can  frequently  get  quite  close  to  one  for  better 
observation  or  for  picture-taking. 

The  Striped  Gopher 

Still  another  prairie  dweller  that  makes  excellent  burrows 
is  the  striped  gopher.  Some,  apparently  used  only  for  shelter,  are 
short.  There  are  also  longer  burrows  that  end  in  nests  where  the 
young  are  born.  Adjoining  rooms  serve  as  storehouses  for  a  large 
supply  of  winter  grain. 

Prospectors  prize  the  gopher  and  other  burrowers  as  good 
"pardners"  because  the  dirt  thrown  up  around  the  opening  of  a 
tunnel  by  the  animal  provides  them  with  underground  soil 
samples.  The  prospector  pans  such  dumps  for  gold  traces. 

Raccoons— Ingratiating  and  iNQuisrrrvE 

If  you  have  a  camper  son  or  daughter  you  may  be  startled 
one  of  these  days  by  the  introduction  into  your  home  of  a  bright- 
eyed  pointed-faced  creature  with  long,  bushy  fur.  This  will  be  a 
raccoon  that  your  youngster  has  adopted  during  the  summer  and 
could  not  bear  to  leave  behind.  Provided  there  is  enough  space 


io8] 


Animals  in  the  Wild 


for  a  roomy  pen,  it  is  possible  to  keep  a  raccoon  in  captivity  success- 
fully—though not  all  raccoons  lend  themselves  to  a  domestic 
routine. 

Not  a  Finicky  Eater:  The  raccoon  relishes  many  different  kinds  of 
food.  It  prowls  the  woods  at  night,  raiding  birds'  and  squirrels' 
nests  for  babies,  eggs,  or  even  adults.  The  black  markings  across 
the  raccoon's  face,  suggestive  of  a  bandit's  mask,  seem  most  appro- 
priate for  such  nighttime  excursions!  The  raccoon  enjoys  fish, 
catching  them  by  a  nimble  technique  which  involves  lying  in  wait 
at  the  edge  of  a  stream  and  hooking  out  with  its  paw  to  seize 
victims  that  swim  within  reach.  It  also  pounces  on  bugs  and 
reptiles,  and  enjoys  all  kinds  of  fruits  and  vegetables. 

Raccoons  have  a  fascinating  way  of  using  their  front  paws  as 
hands.  If  a  raccoon  is  allowed  in  a  house  it  must  be  watched  closely, 
as  it  can  open  latches  and  will  unhesitatingly  try  to  climb  on  any- 
thing at  all.  The  curiosity  of  this  animal  is  boundless. 


'THE  BUCKWAASKED  IIHIE  BEAR" 

This  is  the  name  the  American  Indians  gave  the  raccoon  in  their  stories.  Centuries 
ago  they  learned  to  admire  the  raccoon's  ingenuity,  curiosity,  and  genial  play- 
fulness. The  raccoon  eats  a  large  variety  of  animals,  catching  them  with  ap- 
propriately versatile  techniques.  It  is  said  to  wash  all  food  whenever   possible.

OFFENSIVENESS  IS  THE  BEST  DEFENSE 

The  skunk  is  a  peaceable,  friendly  creature.  When  menaced,  however,  it  resorts 
to  a  nasty  spray  that  can  be  smelled  for  half  a  mile— though  only  the  equivalent 
of  tv/o  or  three  drops  is  emitted!  Skunk's  fur,  of  excellent  quality,  is  often 
marketed    under  the   tactful  trade   names   of   Alaska   sable   and    black    marten. 


Skunks— Friendlier  Than  You  Think 

There  is  another  wild  mammal  an  enthusiastic  young 
camper  may  wish  to  bring  home:  the  skunk.  As  it  is  best  known 
for  the  obnoxious  odor  it  can  give  off,  this  animal  is  likely  to  meet 
with  a  froscy  reception.  It  may  be,  however,  that  the  camp  coun- 
selors have  already  had  the  skunk's  scent  glands  removed.  Most 
owners  of  skunks  do  have  such  an  operation  performed  on  their 
pets,  and  this  is  best  done  while  the  creature  is  still  quite  young. 
A  skunk  makes  a  friendly,  easygoing  pet.  A  small  cage  will  do 
for  its  headquarters;  but  if  the  cage  is  out-of-doors  the  sides  must 
be  carried  well  below  the  surface  of  the  ground.  Skunks  are  expert 
burrowers  and  can  easily  dig  their  way  to  freedom  through  an 
ordinary  earth  floor.  They  can  be  housebroken,  and  they  often 
render  excellent  service  in  catching  mice.

Other  Pets 
Guinea  Pigs:  If  you  adopt  a  skunk,  a  raccoon,  or  a  related  wild 
animal,  you  will  have  a  lively  hobby  to  share  with  your  youngster. 
That  old-time  favorite  among  mammal  pets,  the  guinea  pig,  is 
perhaps  a  more  conservative  choice.  Given  proper  care,  it  is  prac- 
tically odorless,  and  easy  to  feed.  However,  its  habit  of  breaking 
out  in  a  shrill  whistling  sound  may  be  disconcerting  if  you  live 
in  a  city  and  must  keep  your  pets  in  an  apartment  or  a  garage. 

Hamsters:  Hamsters  are  comparative  newcomers  to  the  ranks  of 
furry  pets.  These  rodents  look  like  fat-faced  stubby-eared  squirrels, 
but  are  smaller.  They  have  no  specialized  tastes  in  food  and  are 
free  from  unpleasant  odors.  Friendly  and  winning  in  their  ways, 
hamsters  retain  some  of  the  interesting  habits  of  wild  creatures- 
such  as  hoarding  food  until  they  are  ready  to  consume  it.  Many  a 
hamster  has  a  routine  of  packing  food  into  the  cheek  pouches  that 
extend  over  its  shoulders.  It  carries  the  food  to  a  hiding  place  and 
tucks  it  away;  then  at  night— for  it  tends  to  indulge  in  nighttime 
activity— the  hamster  digs  up  the  buried  food  and  nibbles  away 
contentedly.  It  is  not,  by  the  way,  a  native  American,  but  an 
import  from  Eurasia. 

Bears— Noted  Gourmets 

Nursery  stories  present  such  an  appealing  picture  of  Mother 
Bear,  Daddy  Bear,  and  Baby  Bear  that  a  child  is  all  too  likely  to 
think  of  this  closely  knit  family  group  as  being  true  to  life.  Let's 
look  at  the  facts. 

The  mother-and-baby  bear  relationship  does  really  exist  in 
nature,  but  as  far  as  Daddy  is  concerned,  we  shall  have  to  remove 
him  from  the  scene  if  we  are  to  be  faithful  to  the  facts.  He  actually 
goes  off  by  himself,  taking  no  responsibility  for  feeding,  protecting, 
or  educating  the  young:  The  mother  does  it  all.  In  this  respect 
bears  differ  from  wolves,  foxes,  and  coyotes— in  each  of  those 
families  the  father  does  his  full  share  when  it  comes  to  bringing 
up  the  children. 

The  Playful  Bear  Cub:  Bear  cubs  are  not  handicapped  by  the 
father's  absence,  as  the  mother  takes  care  of  their  needs  in  the

THE  BEAR'S  ROUNDHOUSE  PUNCH 

Black  bears  are  not  large  as  bears  go,  ond  their  top  weight  is  about  three 
hundred  pounds.  They  are  fond  of  berries  and— of  course— honey.  Bears  pack  a 
tremendous,  often  lethal,  wallop  in  their  forepaws;  but  the  ''bear  hug"  is  now 
generally  dismissed  by  scientists  as  a  fable. 


most  competent  fashion.  At  birth  the  twin  cubs  of  a  black  bear 
are  blind,  almost  hairless  and  not  much  larger  than  rats.  By  the 
time  they  leave  the  winter  retreat  where  they  were  born,  they 
have  become  saucy,  fun-loving  creatures  with  fluffy  hair  and  sharp 
claws.  They  box  and  wrestle,  play  hide-and-seek,  and  try  all  sorts 
of  tricks  on  their  mother. 

Sometimes  she  loses  patience  with  them  and  boxes  their  ears. 
For  all  that,  she  guards  them  jealously  and  the  only  time  she  is 
ever  really  dangerous  to  human  beings  is  when  her  cubs  are  with 
her. 

You  may  see  black  bears  in  some  of  our  national  parks;  their 
desire  for  food  from  tourists  has  overcome  their  natural  shyness. 
One  lesson  they  learn  well  in  the  wilderness  is  to  be  ever  wary 
of  humans  and  other  possible  enemies.  Mother  bear  teaches  the 
cubs  to  swim  and  to  climb  trees  to  escape  danger.  She  shows  them 
how  to  tear  apart  rotted  stumps  and  mop  up  swarming  ants  with 
the  tongue.  She  demonstrates  how  to  catch  mice,  how  to  slap  a 


!i3l  Animals  in  the  Wild 

frog  out  of  water,  and  how  to  raid  a  tree  in  which  bees  have 
stored  honey. 

The  Bear's  Sweet  Tooth:  Bears  are  noted  for  being  gourmets. 
Black  bears  live  chiefly  on  vegetables,  but  they  also  dig  for  roots 
and  bugs  and  catch  grasshoppers  and  crickets.  They  enjoy  all 
kinds  of  fruit,  blueberries  being  their  favorite;  and  like  all  bears, 
they  are  so  fond  of  honey  that  they  will  risk  the  vengeance  of 
furious  swarms  of  bees  to  tear  open  and  rob  a  bee  tree. 

Some  black  bears  add  meat  to  this  diet,  but  it  is  said  that  when 
other  food  is  plentiful  they  will  not  show  the  slightest  interest 
in  freshly  killed  deer  or  sheep.  Grizzly  bears  are  flesh  eaters:  They 
hunt  deer  and  wapiti  (an  especially  large  deer),  and  will  even 
attack  cattle  and  horses.  Small  game  is  their  usual  prey,  however, 
and  a  grizzly  will  hunt  mice  tirelessly,  digging  them  out  of  the 
grass  with  his  huge  paws. 

The  Bear's  Long  Sleep:  It  is  probable  that  ir  prehistoric  times 
great  cave  bears,  like  the  "cave  men,"  made  good  use  of  dens  and 
caves  for  shelter  and  safety.  Nowadays  bears  are  chiefly  interested 
in  dens  as  places  to  sleep  in  during  the  winter  months. 

A  female  bear  chooses  a  particularly  snug  retreat,  for  it  is 
during  the  long,  cold-weather  rest  period  that  her  babies  are  born. 
In  the  spring  she  leaves  her  winter  headquarters,  taking  her  cubs 
with  her.  From  then  on,  all  outdoors  is  her  home.  Black  bears 
and  grizzlies  usually  seek  out  a  natural  cave  or  partially  uprooted 
tree  that  will  shelter  them— but  if  need  be,  they  dig  a  hole  under 
some  steep  embankment. 

Foxes  and  Wolves 

Unlike  the  bears,  foxes  remain  together  in  family  groups. 
While  the  young  are  growing  up,  both  parents  take  care  of  them 
in  their  underground  den.  The  red  fox  digs  its  own  burrow, 
often  supplementing  the  living  room  with  a  pantry  and  then 
building  a  tunnel  to  connect  the  food  storage  room  with  the  main 
burrow.  Though  a  fox  family  leaves  its  cozy  home  during  warm 
weather,  it  may  return  to  the  same  winter  address  year  after  year.

JUST  AS  FOXY  AS  HE  LOOKS 

Many  are  the  centuries-old  tales  that  center  about  the  cunn!ng  of  the  fox.  Tha 
red  fox  is  perhaps  the  slyest  of  the  tribe — the  terror  of  the  hen  coops,  but  a  model 
husband  and  father.  The  beautiful  silver  fox  fur  is  highly  prized — a  sad  end  for 
Brer  Fox.  Besides  man,  his  enemies  ore  the  lynx,  wolf,  and  fisher. 

Gray  foxes  do  not  regularly  dig  homes;  they  dwell  in  natural 
cavities  in  rocks  or  in  hollow  trees. 

The  Wolfs  Home:  The  wolf  is  also  partial  to  dens.  Sometimes 
a  wolf  digs  a  short  burrow  in  the  ground;  a  large  hollow  log  or 
an  excavation  under  a  tree  stump  will  also  serve  his  purpose,  and 
in  rock-strewn  regions  he  often  adopts  a  natural  cave. 

Coyotes  are  more  ambitious  when  it  comes  to  constructing  a 
home.  Not  content  with  general  living  quarters  among  secluded 
rocks  or  brush,  the  mother  digs  a  nursery  den,  and  she  may  also 
have  a  separate  resting  den  where  she  can  retire  to  "get  away 
from  it  all."  Not  to  be  outdone,  the  male  digs  a  den  of  his  own 
to  use  while  his  mate  is  caring  for  the  young. 

Lynxes  and  Bobcats— More  Ballyhoo  Than  Ferocity 
The  oversized  bobtailed  cat  known  as  the  lynx  is  frequently 
heard  but  rarely  seen.  This  animal  prefers  night  prowling  to 
daytime  hunting  and  is  therefore  hardly  ever  seen  by  man;  but 


114]  Animals  in  the  Wila 

its  yowls  are  all  too  familiar  to  campers  in  northern  regions  and 
visitors  to  some  of  the  national  parks  who  are  trying  to  doze  off 
to  sleep.  Though  its  call  sounds  terrifying,  the  lynx  usually  seeks 
no  larger  game  than  the  hare  or  smaller  rodents.  On  rare  occasions 
a  lynx  may  leap  from  a  tree  branch  or  ledge  to  kill  a  deer  or  an 
antelope. 

Bobcats,  unlike  lynxes,  are  not  confined  to  the  North.  Bobcat 
trails  may  be  seen  in  Arizona  deserts  or  on  Canadian  snow- 
covered  plains.  "Fighting  like  a  wildcat"  suggests  the  most  vicious 
kind  of  battle  but,  like  the  lynx,  bobcats  usually  prey  only  on 
rabbits,  other  small  rodents,  and  ground-nesting  birds. 

Deer— Appealing  Creatures 

Thanks  to  the  classic  story  of  Bambi,  many  children  take  a 
sympathetic  interest  in  the  white-tailed  deer.  The  young  deer, 
or  fawn,  makes  an  interesting  contrast  with  some  other  mammal 
babies,  such  as  the  blind  and  helpless  bear  cubs.  As  infants,  deer 
are  weak  and  wobbly,  but  they  can  see  immediately  and  before 
long  they  are  anxious  to  explore  their  surroundings.  The  mother, 
or  doe,  scolds  them,  warning  against  such  activity;  if  necessary, 
she  bunts  them  on  the  head  to  make  them  stay  put. 

A  fawn's  spotted  coat  blends  effectively  with  its  surroundings. 
This  enables  it  to  protect  itself  by  merely  lying  still  and  relying 
on  camouflage.  Once  the  mother  has  taught  this  lesson  to  her 
fawns,  she  can  leave  to  seek  food;  but  she  returns  several  times  a 
day  to  nurse  them.  If  an  enemy  is  nearby,  she  will  deliberately 
attract  attention  to  herself  to  save  the  fawns. 

The  Buck's  Antlers:  The  father  of  the  deer  family,  the  buck,  is  a 
handsome,  impressive  animal.  The  buck's  crowning  glory,  his 
antlers,  are  shed  every  year,  and  he  proceeds  to  grow  a  new  pair. 
Considering  the  thousands  of  antlers  discarded  every  year,  your 
child  might  well  expect  the  woods  to  be  carpeted  with  them.  Some 
antlers  are  found,  to  be  sure;  but  many  are  eaten  by  porcupines, 
mice,  and  rabbits  for  their  mineral  content,  while  others  dis- 
integrate after  sufficient  weathering.

Adventures  In  Park  And  Zoo 

The  mammals  of  American  field  and  woodland  have  first  claim 
on  our  children's  interest;  these  animals  are  part  of  the  American 
scene,  and  their  colorful  variety  always  suggests  some  fascinating 
detail  to  absorb  our  attention.  Yet,  somehow,  there  is  a  greater 
enchantment  about  the  exotic  animals  of  faraway  places.  Thrilling 
as  it  is  to  see  a  shy,  graceful  creature  like  the  deer  in  our  native 
woods,  we  often  feel  it  would  be  a  more  exciting  experience  to 
stalk  elephants  and  other  big  game  in  Africa. 

Such  expeditions  are  out  of  the  question  for  most  of  us.  But 
not  altogether.  There  are  little  safaris  we  can  make  close  to  home. 
A  visit  to  the  zoo  is  a  delightful  way  to  make  the  acquaintance  of 
strange  animals  from  every  part  of  the  world.  Throughout  the 
United  States  and  Canada  there  are  a  number  of  fine  zoos  and 
zoological  parks  where  animals  from  Asia,  Africa,  Australia  and 
the  other  continents  may  be  seen  in  the  space  of  a  single  afternoon. 

Showmen  and  Show-Offs 

Every  zoo  has  sights  and  sounds  that  take  us  completely 
out  of  the  daily  round  of  humdrum  living.  But  to  get  the  most 
fun  out  of  a  visit  to  the  zoo,  you  must  have  one  or  more  youngsters 
along  with  you.  You  will  enjoy  their  reactions,  their  curiosity, 
dieir  astonishment.  For  a  visit  to  the  zoo  is  /wn— as  much  fun  as 
the  circus,  and  often  very  much  like  the  circus  if  you  see  the 
animals  at  feeding  time,  or  in  the  spring  when  frisky  babies  en- 
liven many  cages. 

Some  animals,  the  natural  showmen  and  show-offs,  are  enter- 
taining at  all  times.  The  sea  lions  with  their  graceful  diving,  their 
awkward  waddling,  their  hoarse  yawps,  their  bent  for  deadpan 
horseplay,  and  their  efficient  if  not  elegant  eating  habits,  are  great 
favorites.  All  children  are  delighted  with  the  tail-swinging  antics 
of  the  monkeys  and  some  of  their  droll  attitudes  which  caricature 
humans.  The  huge  elephant  with  his  fantastic  trunk  and  his  digni- 
fied, patient  look;  the  tigers  and  leopards  with  their  air  of  sleek 
power,  and  drowsy  laziness;  the  giraffes  with  their  incredibly  long 
necks  and  the  camels  with  their  bumpy  backs— all  these  and  many 


ii6]  Animals  in  the  Wild 

other  inhabitants  of  the  zoo  are  natural-born  showmen  and  show- 
offs  that  children  love  to  watch. 

Your  child's  enjoyment  of  a  visit  to  the  zoo  stimulates  him 
to  learn  more  about  the  animal  world.  Many  exhibits  have  labels 
or  placards  giving  specific  information  about  the  animals.  And 
before  going  on  a  visit,  you  can  prepare  yourself  at  home  with 
some  background  reading— one  of  the  purposes  of  this  chapter  is 
to  supply  you  with  it.  Thus  you  will  be  well  equipped  to  furnish 
details  about  the  animals  or  offer  interesting  information  at  the 
strategic  moment. 

Monkeys— High-Spirited  Performers 

It  is  a  good  idea  to  make  the  Monkey  House  the  first  stop 
on  your  zoo  tour:  There  is  a  special  appeal  in  these  volatile  animals 
and  their  endearing  ways  which  often  remind  us  of  human  beings 
in  miniature.  The  monkeys  also  show  to  good  advantage  because 
cages  are  less  confining  for  them  than  for  the  great  apes  such  as 
the  gorilla  and  the  orangutan. 

The  Rhesus  Monkey:  As  you  watch  a  family  of  rhesus  monkeys 
chasing  each  other,  chattering  and  occasionally  screaming,  it  is 
easy  for  you  to  picture  them  in  their  native  jungles  of  India. 
They  behave  there  pretty  much  the  same  way,  quarreling  and 
screeching  at  each  other  one  moment,  then  suddenly  quieting 
down  and  grooming  each  other's  fur.  Thousands  of  rhesus  monkeys 
are  brought  to  the  United  States  each  year  to  be  placed  in  zoos 
or  to  be  used  for  medical  research. 

Swinging  by  the  Tail:  The  woolly  monkey  is  one  of  the  largest 
of  the  species  native  to  South  America.  When  you  see  one  at  the 
zoo,  it  is  interesting  to  contrast  its  antics  with  the  gambols  of 
the  rhesus.  You  can  observe  the  woolly  monkey  swing  daringly 
from  branches  or  bars  by  its  tail.  No  matter  how  long  you  watch 
the  rhesus,  it  will  never  duplicate  this  feat.  The  point  is  that  the 
woolly  monkey  is  one  of  the  species  that  has  a  prehensile  tail— a 
"grasping"  tail  that  functions  in  effect  as  a  fifth  limb  or  extra  hand. 
Only  the  monkeys  of  Central  and  South  America  have  a  pre^ 
hensile  tail.  The  species  with  the  longest  tail  of  the  monkey  tribe

RAUCOUS  BUT  AMIABLE 
Tlhe  well-named  howler  monkey,  a   talented   climber  and   swinger,   relies  on   its 
prehensile  tail,  which  in  effect  serves  as  a  fifth   paw,  or   hand.  At  the  zoo,  the 
howler  performs  amazing  acrobatic  feats,  every  now  and  then  pausing  thoughtfully

live  in  India,  and  of  course  this  tail  is  not  prehensile.  As  for  the 
howler  monkey,  its  prehensile  tail  is  "different"— the  fur  is  missing 
from  the  inner  portion  near  the  tip. 

It  is  curious  that  many  of  the  larger  monkeys  are  afraid  of  the 
water;  not  so  the  rhesus,  which  is  a  good  swimmer. 

As  for  tastes  in  food,  monkeys  thrive  on  a  leafy  diet  and  on 
such  fruit  as  apples  and  bananas.  Those  living  in  the  natural  state 
augment  this  diet  in  one  way  or  another.  The  South  American 
squirrel  monkey,  for  example,  eats  insects,  and  possibly  young 
birds. 

Despite  their  general  reputation  for  amiability,  not  all  monkeys 
are  good  pet  or  exhibition  material.  One  of  the  most  attractive 
species,  the  lion-tailed  monkey,  is  likely  to  turn  savage  if  removed 
from  its  native  forests  in  western  India.  Even  the  Indians,  who 
have  a  way  with  animals,  cannot  keep  the  lion-tailed  monkey  in 
captivity  successfully.

The  Big  Apes 

Gorillas— Shy  and  Retiring:  When  you  see  the  gorillas  behind 
the  bars  at  the  zoo,  they  impress  you  as  fierce  and  vicious.  Some- 
times a  gorilla  acts  that  way  as  well— spitting  at  its  admiring 
audience  and  carrying  on  as  if  trying  to  pull  the  cage  apart.  In 
their  natural  surroundings,  however,  the  disposition  of  these  ani- 
mals is  quite  different.  While  they  may  occasionally  attack  men 
or  animals  in  self-defense,  they  are  by  nature  shy  and  retiring 
and  prefer  to  stay  clear  of  trouble  whenever  possible. 

On  their  native  grounds,  gorillas  roam  about  in  small  family 
groups  in  search  of  the  vegetables,  roots  and  fruit  on  which  they 
feed.  Though  they  can  stand  upright  as  humans  do,  and  their 
babies  often  walk  that  way,  older  gorillas  always  walk  on  all  fours. 

Their  great  strength  notwithstanding,  gorillas— like  many  wild 
animals— have  rather  frail  health.  In  the  wild  state  they  are  dis- 
tressed by  jungle-bred  worms  which  bring  on  intestinal  troubles; 
in  captivity  gorillas  are  very  susceptible  to  colds  and  pneumonia. 

Chimpanzees— Intelligent  and  Comical:  The  chimpanzee  is  as 
widely  known  for  its  intelligence  as  for  its  comical  antics.  It  can 
be  taught  all  sorts  of  tricks  and— what  is  more  impressive— it  often 
shows  actual  reasoning  powers.  Like  the  gorillas,  chimpanzees 
dwell  in  Africa  and  they  also  live  on  fruit  and  vegetables.  They 
are,  however,  much  smaller  than  gorillas.  An  adult  male  rarely 
attains  more  than  175  pounds,  while  a  gorilla  may  reach  six 
hundred  or  more. 

Chimps  can  walk  upright  but— again  like  the  gorillas— they 
usually  travel  on  all  fours  with  their  hands  curled  into  fists. 
Though  their  hands  resemble  those  of  humans,  chimpanzees  lack 
manipulative  powers— particularly  in  the  thumbs. 

Orangutans—Slow  and  Deliberate:  "Man  of  the  Woods"  and 
"Wild  Man"  are  alternative  renderings  for  the  orangutan's  Malay 
name.  This  big  ape  of  Borneo  and  Sumatra  lives  almost  entirely 
among  leafy  branches  and,  despite  its  bulk,  swings  with  great 
agility  from  one  tree  to  another.  Though  it  is  capable  of  moving 
speedily,  it  is  usually  slow  and  deliberate.  A  big  male  orang  weighs 
two  hundred  pounds  or  more.

Elephants—Largest  Land  Animals 

Children  love  elephants.  This  animal  is  interesting  to 
observe  for  many  reasons:  its  huge  size,  its  amazing  trunk,  its 
tusks  from  which  ivory  is  obtained,  its  status  as  a  living  relic  of 
the  great  mammoths  that  roamed  the  earth  many  ages  ago,  and  its 
wise,  benign  expression  that  reminds  us  of  some  distinguished 
elder  statesman. 

Having  been  told  that  the  elephant  is  the  largest  land  mammal, 
a  child  may  be  puzzled  by  its  tough,  wrinkled  skin. 

"I  thought  all  mammals  had  fur  or  hair,'*  he  may  tell  you. 
"But  the  elephant's  a  mammal  and  look  at  him." 

Indeed,  this  skeptical  attitude  is  well  taken,  for  adult  elephants 
are  almost  completely  devoid  of  hair.  You  have  to  look  closely  to 
see  even  a  bit  of  it  on  their  hide.  A  young  elephant,  however,  is 
covered  with  a  fuzzy  coat.  Several  other  beasts,  such  as  the  adult 
rhinoceros  and  hippopotamus,  follow  this  pattern  of  being  nearly 
hairless. 

The  Elephant's  Trunk:  Elephants  at  the  zoo  are  particularly 
fascinating  because  we  are  allowed  to  feed  them  and  thus  see  in 
action  the  amazing  "nose"  which  serves  them  as  arm,  hand,  and 
fingers.  The  size  and  muscular  strength  of  an  elephant's  trunk 
make  it  possible  for  him  to  carry  heavy,  bulky  objects;  the  finger- 
like tabs  that  project  from  the  end  of  the  trunk  enable  him  to 
pick  up  an  object  as  small  as  a  peanut  and  swing  it  through  a  great 
arc  into  his  mouth.  At  the  end  of  an  African  elephant's  trunk 
there  are  two  tabs  of  about  equal  length.  An  Indian  elephant  has 
only  one  tab. 

Elephants  of  Africa  and  India  can  also  be  distinguished  by  size. 
As  a  rule  the  African  species  grow  considerably  larger  than  the 
Indian  variety  and  their  ears  are  much  larger.  In  the  jungles  of 
west  Africa,  however,  there  are  elephants  that  are  an  exception 
to  this  rule.  These  elephants  are  often  described  as  pygmies  or 
dwarfs,  as  they  average  considerablv  less  in  size  than  most  African 
elephants.

Animals  in  the  Wild 


A  LOT  OF  ANIMAL 

The  African  elephant,  weighing  five  or  six  tons,  is  bigger  than  its  Indian  cousin— 
in  fact  the  largest  of  all  land  animals.  It  grows  to  a  height  of  eleven  or  twelve 
feet,  and  has  two  tusks  that  average  about  ten  feet  in  length  and  250  pounds 
in  weight.  It  has  been  claimed  that  the  powerful  but  delicate  trunk  contains  as 
many  as  forty  thousand   muscles!   Indian  species  has  smaller,   less  fanlike  ears. 


Training  an  Elephant:  You  see  the  Indian  elephants  far  more 
frequently  in  zoos  and  circuses  than  the  African  species;  the  Indian 
animals,  aside  from  being  smaller,  are  obtained  more  easily  and 
can  be  trained  more  rapidly.  For  thousands  of  years  the  natives 
of  eastern  India  have  been  skilled  in  the  training  of  elephants, 
and  the  knack  has  been  handed  down  from  father  to  son. 

An  important  factor  in  their  success  lies  in  the  use  of  the  human 
voice:  The  trainer  first  wins  his  charge's  trust  by  softly  chanting 
an  "elephant  song,"  after  which  he  bribes  the  beast  with  its 
favorite  foods.  (Wild  elephants  eat  leaves  and  grass—perhaps  half 


Animals  in  the  Wild  [121 

a  ton  in  a  single  day!— but  they  relish  sweet  fruits  and  other 
dainties.  In  the  zoo  they  are  fed  mostly  on  hay  and  grain.) 

Besides  drilling  some  elephants  for  circus  performance,  the 
natives  of  India  train  others  for  use  in  hunting  and  for  carrying 
heavy  materials— an  important  consideration  in  a  land  lacking 
machinery.  In  ancient  days  elephants  played  an  impressive  role 
in  warfare  as  forerunners  of  the  modern  giant  tank.  The  most 
famous  instance  of  their  military  use  was  in  Hannibal's  great 
victory  over  the  Romans  at  Cannae  after  he  had  brought  these 
huge  creatures  across  a  pass  over  the  Alps.  In  time  elephants  fell 
out  of  military  favor  because  they  were  too  easily  terrified  by  the 
noise  and  violence  of  battle. 

Elephants  have  always  excited  a  great  deal  of  interest  and  many 
curious  beliefs  have  grown  up  about  them.  One  of  these  is  that 
elephants  are  afraid  of  mice!  There  seems  to  be  no  scientific  evi- 
dence for  this  notion.  Another  fallacious  idea  is  that  elephants  live 
a  century  or  more.  Scientists  believe  that  the  life  span  of  these 
giant  mammals  is  about  the  same  as  that  of  human  beings— from 
sixty  to  eighty  years. 

Hippos— "River  Horses" 

Next  in  size  to  the  elephant  is  the  grotesque  African 
hippopotamus,  which  may  achieve  a  weight  of  four  tons— or  more! 
It  is  perhaps  this  creature's  very  ugliness  that  makes  it  appealing 
to  children.  Though  the  hippo  performs  no  stunts,  they  watch  it 
with  absorbed  interest. 

The  Hippo  in  the  Water:  The  hippopotamus  spends  a  great  deal 
of  time  in  the  water,  which  must  always  be  provided  in  its  en- 
closure. In  the  wild  state  the  hippo  seeks  out  the  calm  waters  of  a 
tropical  river  where  it  browses  on  water  plants  as  it  swims  or 
floats.  (The  name  hippopotamus  means  "river  horse.")  When 
frightened,  a  hippo  takes  to  flight  by  sinking  to  the  river  bot- 
tom, where  it  can  walk  easily  and  quickly.  Ten  minutes  is  about 
the  longest  it  can  stay  under  water,  and  when  it  comes  to  the 
surface  it  usually  spouts  a  column  of  air  from  its  nostrils. 

A  mother  hippo  often  rides  her  baby  on  her  back  in  the  water, 
and  the  young  one  clings  there  even  when  they  go  below  the

THE  MONUMENTAL  HIPPO 

This  four-ton  river  horse  is  anything  but  glamorous— yet,  despite  the  hippo's 
ugliness,  children  enjoy  observing  it,  perhaps  because  of  its  great  size  and  mild 
manner.  Its  enormous  mouth  and  tusklike  teeth  are  exercised  exclusively  on 
vegetation.  The  African  natives  hunt  it  for  its  flesh  and  its  tusks. 


surface  I  Once  your  child  realizes  the  extent  to  which  hippos  are 
water  animals,  he  may  see  the  advantage  of  their  peculiarly  placed 
eyes,  ears,  and  nose.  All  these  features  are  at  about  the  same  level 
on  top  of  the  animal's  huge  flat  head.  Thus  the  hippo  need  keep 
only  a  small  part  of  its  head  above  water  in  order  to  see,  hear, 
and  breathe  at  times  when  all  the  rest  of  its  body  is  submerged. 

The  Unpredictable  Rhino 

Like  the  elephant,  the  rhinoceros  is  native  to  both  Africa 
and  India.  You  can  tell  the  African  "black"  rhino  by  its  two 
horns;  the  large  Indian  rhino  has  only  one  horn.  Rhinos  spend 
much  of  their  time  sleeping  and  browsing  on  twigs.  They  have 
remarkably  keen  senses  of  smell  and  hearing  and  they  are  quickly 
alert  to  danger.  They  may  charge  an  enemy  with  surprising 
agility  or  do  a  right-about-face  and  gallop  away.  Poor  eyesight 
makes  their  actions  especially  unpredictable.  They  were  once 
much  more  plentiful  than  they  are  today,  for  hunters  have  greatly 
reduced  the  numbers  of  these  '*nose-homs"  (the  literal  meaning 
of  "rhinoceros") .

The  Big  Cats 

Tigers  and  lions  appeal  strongly  to  the  average  child 
because  of  his  affection  for  pussy  cats.  A  small  cub  appears  as 
gentle  and  playful  as  a  kitten,  and  even  an  adult— particularly  a 
tiger— suggests  a  giant  "tabby." 

Lions  and  tigers  are  the  two  biggest  members  of  the  cat  family. 
Some  kinds  of  tiger  grow  considerably  larger  than  others.  The 
Bengal  tiger,  one  of  the  best  known,  may  be  twelve  feet  long  and 
weigh  more  than  five  hundred  pounds.  The  Siberian  tiger,  which 
is  even  larger,  also  has  longer,  heavier  hair  to  protect  it  in  the 
cold  northern  forests  where  it  lives. 

Tigers— "Ten  Pounds  of  Meat  a  Day":  A  mother  tiger  has  two  to 
four  babies  in  a  litter.  In  a  zoo,  tiger  babies  are  sometimes  raised 
by  human  foster  parents  who  feed  them  milk  from  nursing  bottles. 
In  captivity  they  sleep,  purr,  play,  and  chase  their  tails  like  the 
kittens  that  are  so  dear  to  the  hearts  of  children.  In  the  natural 
state  young  tigers  start  killing  small  game  by  the  time  they  are 
seven  months  old.  They  stay  with  their  family  about  two  years. 
The  usual  diet  of  a  tiger  is  wild  game,  such  as  deer,  but  many 
prey  on  sheep,  cattle,  and  other  domestic  animals.  Occasionally  a 
tiger  turns  man-eater  and  becomes  a  serious  menace  to  the  com- 
munity. Well-fed  tigers  in  a  zoo  are  usually  peaceable  and  con- 
tented. It  takes  about  ten  pounds  of  meat  a  day  to  keep  them 
that  way! 

Lions— Not  So  Lionhearted 

A  lion  may  also  become  a  man-killer,  but  it  is  more  usual 
for  him  to  avoid  humans  whenever  possible.  By  day,  lions  like  to 
rest  quietly  in  shady  places;  at  night,  they  are  on  the  alert,  seek- 
ing such  game  as  zebra  and  antelope.  The  cliches  "king  of  beasts'* 
and  "brave  as  a  lion"  help  keep  alive  the  idea  that  lions  are  the 
most  daring  and  courageous  of  all  the  animals.  But,  though  they 
look  the  part,  they  do  not  really  live  up  to  it. 

According  to  Frank  Buck,  the  famous  "Bring  'em  Back  Alive" 
animal  collector,  a  tiger  is  often  self-confident  enough  to  take  on  a 
more  powerful  foe— a  water  buffalo,  for  example— but  a  lion  rarely

LEO  THE  LION 

Lions  like  each  other's  society  more  than  tigers,  and  groups  of  ten  or  twenty

undisturbed  when  visitors'  cars  go  by. 

tries  to  overpower  any  animal  that  is  a  match  for  it.  Mr.  Buck 
discovered,  furthermore,  that  lion  cubs  are  more  tame  than  tiger 
cubs,  and  that  older  lions  are  more  amenable  to  the  company  of 
humans  than  tigers  are. 

A  male  lion  is  far  more  handsome  than  his  mate,  because  of 
the  great  ruff  around  his  neck.  A  lioness  may  have  as  many  as  six 
cubs  in  one  litter.  They  are  completely  helpless  at  first,  as  their 
eyes  do  not  open  for  about  a  week.  Sometimes  they  suffer  from 
the  once-common  childhood  ailment  of  rickets,  and  teething  may 
give  them  a  great  deal  of  trouble. 

Giraffes— Walking  SKYscaiAPERs 

Children  are  naturally  fascinated  by  the  giraffe,  the  world's 
tallest  animal,  because  of  its  long  neck.  A  youngster  who  already 
knows  something  about  anatomy  may  wonder  whether  this  un^

THE  TALLEST  OF  THEM  AU 

The  giraffe  has  many  interesting  features  aside  from  its  long  neck.  It  sleeps 
standing,  and  it  can  go  without  formal  drinking  for  weeks,  getting  enough 
moisture  from  foliage.  Its  spotted  coloring  blends  admirably  with  its  surroundings, 
and    its    fleet    legs    make    a    quick   getaway    possible    when    danger    threatens. 


gainly  animal  has  more  than  the  normal  number  of  vertebrae 
from  head  to  shoulders.  It  does  not,  however.  It  has  the  usual 
seven  neck  vertebrae— they  are  simply  longer  than  those  of  other 
mammals. 

The  long  neck  makes  it  possible  for  the  giraffe  to  feed  on  the 
leaves  of  trees.  It  can  manage  to  reach  its  head  down  to  a  pool 
for  drinking  water,  but  it  depends  for  most  of  its  liquid  nourish- 
ment on  the  moisture  on  leaves.  As  you  may  have  guessed,  the 
giraffe  can  cover  ground  speedily  with  its  long  legs,  and  has  been 
known  to  go  over  thirty  miles  an  hour!  The  giraffe  reputedly  is 
silent,  but  at  times  it  does  produce  a  sound  somewhat  like  a  cow's 
moo.

DESERT  TRANSPORT  WITH  BUILT-IN  COMMISSARY 

The  camel  was  domesticated  thousands  of  years  ago— it  is  pictured  on  ancient 
pottery  and  Assyrian  friezes.  The  hump  is  not  part  of  the  camel's  backbone,  but 
a  reserve  supply  of  fat  which  is  gradually  absorbed  as  needed.  The  camel 
olso    keeps    a    water    reservoir    in    its    innards    to     provide    for    emergencies. 


Camels— Avid  Water  Drinkers 

The  camel  is  another  one  of  those  animals  that  interest 
children  because  of  a  physical  peculiarity.  At  some  zoos  children 
need  not  content  themselves  with  looking  at  a  camel;  they  may 
ride  on  the  animal  as  well.  Thus  they  can  come  to  know  some- 
thing of  the  sensation  of  a  desert  traveler  as  he  progresses  over 
the  sands  on  camel-back.  Of  course  the  youngsters  do  not  have  a 
chance  to  appreciate  how  this  useful  animal  weathers  a  sand- 
storm in  its  natural  surroundings.  The  camel  can  close  its  nostrils 
against  the  flying  sand,  and  in  addition  its  double  row  of  eye- 
lashes offers  excellent  protection  for  its  eyes.  A  one-humped  drome- 
dary in  good  form  can  travel  nearly  a  hundred  miles  a  day. 


Animals  in  the  Wild  [127 

Going  Without  Water:  The  accompiishment  for  which  camels  are 
most  noted— the  ability  to  do  without  water— seems  more  improb- 
able than  ever  if  you  see  them  drinking.  When  a  supply  is  avail- 
able, a  camel  will  drink  six  or  seven  gallons  of  water  a  day!  A  camel 
bearing  a  heavy  load  cannot  go  without  drink  for  much  more 
than  three  days;  but  records  show  that  some  animals  have  survived 
for  several  weeks  without  water.  At  such  times  the  camel  draws 
upon  moisture  stored  in  its  stomach  walls  and  actually  "drinks 
from  the  inside."  The  one-humped  camel  is  still  a  valued  beast 
of  burden  in  Africa  and  the  Arab  lands. 

The  Two-humped  Camel:  The  two-humped  Bactrian  camel  grows 
a  far  heavier  coat  than  the  dromedary.  Its  native  land  is  Central 
Asia,  where  many  people  depend  on  their  camels  not  only  for 
transportation  but  also  for  food  (they  drink  the  milk  and  eat 
the  meat)  and  for  clothing  (made  from  the  hair) .  In  the  spring  a 
camel  looks  disreputable  as  its  winter  coat  peels  off  in  ragged 
patches.  Flabby  humps  are  a  sign  of  poor  physical  condition,  as 
the  hump  provides  a  storehouse  of  reserve  nourishment  which 
the  animal  draws  upon  when  food  is  scarce. 

Zoo  Bears— Surprisingly  Timid 

Children  enjoy  watching  bears  because  they  are  reminded 
of  their  beloved  teddy  bears.  At  the  zoo,  aside  from  the  familiar 
native  North  American  black  bear,  you  may  also  see  several  more 
spectacular  or  unusual  species. 

The  Alaskan  Brown  Bear:  A  large  zoo  may  be  able  to  exhibit  the 
biggest  bears  in  the  world— the  Alaskan  brown  bear.  Some  of  them 
weigh  fifteen  hundred  pounds  or  more.  Despite  their  great  power 
and  tremendous  claws,  they  are  timid  rather  than  daring  and 
attack  only  when  cornered  or  wounded.  As  in  the  case  of  other 
bears,  the  cubs  are  amazingly  tiny  compared  to  the  adults.  A  baby 
bear  weighs  about  a  pound  and  a  half  at  birth. 

The  Polar  Bear:  Some  polar  bears  are  as  heavy  as  the  Alaskan 
brown  bear,  though  the  average  male  is  not  over  nine  hundred 
pounds.  This  bear  does  not  have  the  timidity  of  most  species.  It 
is  a  hunter  that  preys  upon  fish,  seals,  walrus,  and  it  will  stalk  a

THE  POLAR  BEAR  DOES  NOT  SEEM  TO  MISS  ITS  ICE  FLOES 

At  first  thought  it  seems  astonishing  that  this  native  of  the  Arctic  regions  can 
thrive  in  temperate-zone  zoos.  Apparently  the  polar  bear  is  not  uncomfortable 
so  long  as  it  has  a  chance  to  immerse  itself  in  a  refreshing  pool.  This  animal 
has  a  keen  sense  of  smell  in  detecting  food  or  enemies. 

man  in  the  same  way  that  it  pursues  the  large  mammals.  The 
polar  bear  mother,  like  all  bear  mothers,  is  a  conscientious  guard- 
ian and  teacher  of  her  cubs.  She  frequently  offers  them  a  unique 
towing  service  in  the  water,  allowing  them  to  grip  her  tail  with 
their  teeth! 

The  Grizzly  Bear:  You  may  look  with  some  awe  at  the  grizzlies, 
as  they  have  won  a  reputation  as  the  most  ferocious  of  all  bears. 
Books  about  the  lives  of  the  American  pioneers  and  frontiersmen 
contain  many  accounts  of  struggles  with  grizzlies.  If  wounded  or 
fearful  for  their  cubs,  they  may  kill  a  man— but  they  do  not  go  out 
of  their  way  to  hunt  him.  Grizzlies  live  chiefly  on  fruit,  berries, 
insects,  fish,  and  small  mammals. 

The  Giant  Panda— Children's  Favorite 

Few  zoos  are  in  a  position  to  exhibit  so  rare  an  animal  as 
the  giant  panda,  but  wherever  it  is  shown,  this  strikingly  marked 
black  and  white  mammal  makes  an  immediate  hit  with  children. 
Not  until  1937  was  a  giant  panda  captured  alive.  It  was  a  baby, 
and  had  many  of  the  appealing  ways  of  a  human  baby.  It  romped

"THE  BLACK-AND-WHITE  BEAR" 

In  its  toddler  stage  the  giant  panda  is  playful  and  appealing— one  of  the  200'$ 
outstandingly  popular  performers.  But  the  grown-up  giant  panda,  which  weighs 
about  three  hundred  pounds,  does  not  relish  captivity  and  is  apt  to  be  surly, 
not  to  say  downright  bad-tempered. 

in  a  play  pen,  took  milk  from  a  nursing  bottle,  and  when  it  was 
tired  it  whimpered  like  a  human  infant.  It  was  named  Su-Lin, 
which  has  been  translated  as  "a  little  bit  of  something  mighty 
cute." 

Since  the  time  of  Su-Lin*s  introduction  into  the  United  States, 
more  than  a  dozen  giant  pandas  have  been  captured  and  brought 
from  their  homes  in  western  China  to  zoos  in  the  United  States 
and  Europe.  An  unfortunate  aspect  of  the  pandas'  scarcity  is  that 
when  one  of  them  dies,  it  is  not  easily  replaced.  Although  this 
animal's  appearance  reminds  us  of  a  bear,  it  is  more  closely  related 
to  the  raccoon.  In  the  wild  state  the  panda  is  believed  to  live  on 
bamboo  leaves  and  stems;  in  a  zoo  corn-meal  mush,  nourishing 
if  less  exotic,  forms  a  large  part  of  its  diet. 

Oddities  from  Australia 

Among  the  most  remarkable  creatures  in  our  zoos  are 
several  near-extinct  Australian  animals.  Even  in  Australia  these 
believe-it-or-not  leftovers  from  prehistoric  times  can  generally  be 
seen  only  in  zoos.

The  Platypus—Scrambled  Mammal:  The  strangest  of  these 
strange  creatures  is  perhaps  the  platypus,  which  has  a  bill  like  a 
duck's  and  grows  to  a  length  of  about  eighteen  inches.  It  is  con- 
sidered a  mammal  because  it  feeds  its  young  on  its  own  milk, 
and  because  it  has  hair  and  is  warm-blooded.  But  the  platypus 
lays  eggs,  and  the  temperature  of  its  blood  changes  to  some  extent, 
depending  on  the  weather.  Most  curious  of  all,  the  nursing  tech- 
nique of  the  mother  platypus  is  highly  unorthodox:  Milk  oozes 
from  special  pores  in  her  skin  and  clings  to  her  fur,  from  which 
the  babies  lap  it  up.  The  platypus  is  considered  one  of  the  most 
primitive  of  mammals— in  some  ways  it  is  very  close  to  the  reptiles.

THE  CURIOUS  KANGAROO 

As  a  reMc  of  prehistoric  times,  the  kangaroo  has  traits  that  are  ofF  the  beaten 
track  in  our  own  prosaic  era.  Its  offspring,  only  an  inch  long— or  less!— at  birth, 
is  not  strong  enough  to  suck  milk.  However,  the  milk  is  pumped  automatically

The  Kangaroo's  Built-in  Baby  Carriage:  Children  have  always 
been  intrigued  by  the  kangaroo  and  its  built-in  baby-carriage 
features.  This  animal  is  the  largest  and  most  spectacular  of  the 
marsupials— a  kind  of  mammal  remarkable  for  having  small,  un- 
developed babies  that  spend  their  first  weeks—or  months— in  a 
pouch  on  the  mother's  abdomen. 

Usually  a  kangaroo  mother  has  only  one  baby  at  a  time  and 
the  infant  stays  in  the  nursery  pouch  for  five  or  six  months.  After 
that  the  baby  pokes  its  head  out  and  often  hops  out  to  explore  on 
its  own;  when  it  gets  tired  or  hungry,  it  quickly  dives  back  again. 

The  kangaroo  can  jump  over  a  five-foot  fence  with  ease,  and 
may  even  leap  more  than  twice  that  height.  In  Australia,  the 
animal  has  been  trained  to  be  a  skillful  boxer.  It  is  a  vegetarian, 
and  lives  about  ten  or  fifteen  years.  Smaller  types  of  kangaroos 
are  known  as  wallabies. 


THE  AUSTRALIAN  TEDDY  BEAR 

The  koala  fascinates  children  by  its  droll  resemblance  to  a  teddy  bear  as  well 
as  by  its  gentle,  wistful  expression.  On  its  native  grounds  the  koala,  a  leaf-eater, 
lives  in  tall  trees  and  leaps  sure-footedly  from  branch  to  branch,  as  far  as  five 
feet  at  a  time.  Zoo  keepers  must  feed   it  its   natural  diet  of  eucalyptus  leaves. 


132  ]  Animals  in  the  Wild 

The  Koala— Nature's  Teddy  Bear:  The  appeal  of  the  koala  is 
much  the  same  as  that  of  the  giant  panda— it  looks  like  the  work 
of  a  toy  designer.  In  fact,  some  people  believe  that  the  koala 
inspired  the  long-popular  "teddy  bear."  (The  "teddy"  part  of 
the  name  is  supposed  to  have  been  in  honor  of  Theodore  Roose- 
velt.) Like  the  kangaroo,  the  koala  is  a  marsupial.  A  newborn 
baby  is  less  than  an  inch  long,  and  it  stays  in  the  mother's  pouch 
for  about  two  months.  After  emerging,  the  baby  clings  to  the  fur 
on  the  mother's  back,  riding  there  until  it  becomes  quite  a  heavy 
load. 

SSA  Lions  and  Seals— Nature's  Clowns 

It  is  the  easily  tamed  and  trained  sea  lions  that  you  usually 
see  in  zoo  and  circus.  They  are  born  show-offs.  In  the  zoo 
their  feeding-time  antics  never  fail  to  draw  a  large  and  admiring 
crowd.  Children  and  grown-ups  alike  chortle  with  delight  at  the 
nonchalant  way  in  which  the  sea  lion  holds  his  mouth  wide  open 
and  catches  the  fish  thrown  to  him  by  the  keeper  across  the  length 
of  the  pool.  The  sea  lion  is  also  an  expert  circus  performer, 
balancing  a  large  ball  on  his  nose,  "answering"  questions,  and 
"playing"  musical  instruments. 

"What  is  the  difference  between  a  sea  lion  and  a  seal?"  you 
may  wonder  as  you  watch  the  frolicking  acrobatic  water  mammals 
at  the  zoo. 

Though  many  people  use  the  names  interchangeably,  sea  lions 
differ  somewhat  from  true  seals.  To  recognize  a  sea  lion,  look  for 
ears  at  the  sides  of  his  sleek  head.  They  are  small  but  distinguish- 
able. True  seals  have  no  external  ear  structure.  Sea  lions  are  also 
unique  in  their  ability  to  turn  their  hind  flippers  forward  and 
under,  making  possible  a  fairly  rapid  if  awkward  progress  over 
land. 

Under  natural  conditions  sea  lions  spend  considerable  time 
on  shore,  and  there  the  babies  are  born.  The  mothers  take  them 
to  shallow  water  to  teach  them  how  to  swim  and  catch  fish.  Sea 
lions  live  only  along  the  Pacific  coast.  The  common  seal  is  found 
along  the  shores  of  both  the  North  Atlantic  and  North  Pacific 
Oceans.  The  common  seal    (known  also  as  the  harbor  seal)    is

notably  tame  and  friendly  with  humans,  and  has  a  strong  sense 
of  curiosity. 

Walruses— Timid  Giants 

Most  children  will  look  forward  eagerly  to  seeing  a  walrus 
in  the  flesh  if  they  are  familiar  with  Tweedledee's  nonsensical 
recitation  about  the  Walrus  and  the  Carpenter  in  Through  the 
Looking-Glass.  Everyone  knows  the  famous  passage  in  which  the 
Walrus  pompously  declaims: 

"The  time  has  come**  the  Walrus  said, 

To  talk  of  many  things: 
Of  shoes— and  ships— and  sealing-wax-^ 

Of  cabbages— and  kings— 
And  why  the  sea  is  boiling  hot— 

And  whether  pigs  have  wings," 

The  walrus  is  a  mighty  creature  often  weighing  a  ton  or  more 
and  reaching  a  length  of  about  ten  feet.  Its  name  is  derived  from 
the  Scandinavian  for  "whale  horse,"  an  allusion  to  its  size  and 
the  fact  that  it  lives  both  on  the  land  and  in  the  sea.  The  walrus 
gives  no  lively  performance  as  seals  do;  its  appearance  is  a  show 
in  itself.  The  bristly  whiskers  and  the  male's  fantastically  elongated 
upper  canine  teeth— they  sometimes  reach  a  length  of  thirty 
inches!— enhance  the  formidable  impression  made  by  the  walrus. 

For  all  their  size  and  power,  walruses  are  rather  timid  and  try 
to  avoid  trouble.  They  live  in  herds,  and  if  one  member  is 
attacked,  all  the  rest  rush  to  its  defense.  They  can  fight  fiercely 
if  they  have  to,  making  good  use  of  their  tusks,  and  a  mother  never 
hesitates  to  show  fight  if  an  enemy  approaches  her  "baby."  The 
walrus  has  an  unearthly  bellow  that  is  in  keeping  with  its  appear- 
ance. 

Bats  and  Nature's  Radar  System 

Each  season  half  a  million  people  visit  Carlsbad  Caverns 
in  New  Mexico.  They  are  almost  as  interested  in  the  bats  they 
may  see  there  as  in  the  cave  itself.  Each  afternoon  hordes  of  the 
flying  mammals  come  out,  literally  darkening  the  sky  as  they  set 
out  in  quest  of  food.  It  is  estimated  that  there  are  millions  of  bats 


134  ]  Animals  in  the  Wild 

in  this  colony!  They  are  the  little  brown  bats,  of  which  there  are 
more  than  two  dozen  kinds  in  the  United  States. 

Bats  are  not  good  zoo  exhibition  subjects  because  they  sleep  in 
the  daytime.  Aside  from  roosting  at  Carlsbad  and  other,  smaller, 
caves,  the  little  brown  bat  takes  refuge  in  hollow  trees  and  under 
the  roofs  or  eaves  of  houses.  Your  child  may  shudder,  as  many 
adults  do,  at  the  thought  of  a  bat's  approach.  It  is  a  pity  that  so 
many  superstitions  have  grown  up  about  these  creatures  of  dark- 
ness. Despite  their  sinister  appearance  they  are  really  useful 
animals,  as  they  eat  large  numbers  of  insects— catching  them  in 
mid-flight. 

Occasionally  bats  do  become  entangled  in  a  human  being's 
hair.  Such  incidents  are  accidental— never  intentional.  As  a  matter 
of  fact  the  bat  rarely  flies  into  things,  thanks  to  its  own  special 
radar  system.  As  it  flies  it  emits  high-pitched  squeaks— far  too 
shrill  to  be  caught  by  the  human  ear.  The  sound  waves  hit  any 
nearby  solid  objects  and  bounce  back,  a  signal  to  the  bat  to 
swerve  aside. 

A  Four-foot  Wingspread:  The  "flying  fox,"  the  world's  largest 
bat,  lives  in  India  and  on  tropical  islands  of  the  Pacific.  Its  wing- 
spread  measures  more  than  four  feet  from  tip  to  tip.  The  flying 
foxes  live  on  fruit  and  leave  their  tree  roosts  at  night  to  fly  to 
orchards  or  wild  fruit  trees,  often  traveling  many  miles  to  their 
goal.  Because  of  their  potential  danger  to  fruit,  none  of  these 
bats  may  be  brought  into  the  United  States,  even  for  a  zoo. 

Blood-sucking  Bats:  The  vampire  bat  is  the  one  kind  of  bat  that 
really  deserves  a  place  in  horror  tales;  it  actually  lives  on  the 
blood  of  animals  and  humans.  At  dusk  these  vampire  bats,  which 
dwell  in  Mexico  and  tropical  South  America,  begin  their  hunt 
for  cattle,  wild  creatures,  or  human  beings  who  are  susceptible 
to  attack  through  living  in  unscreened  homes. 

A  bite  from  the  vampire  bat's  sharp  teeth  is  not  painful— nor 
would  it  be  harmful  except  that  sometimes  this  bat  is  infected 
with  a  disease  that  is  transmitted  to  the  victim  and  usually  proves 
fatal.  The  vamoire  laps  the  blood  as  it  flows  from  the  wound.

Mammals  in  Maps,  Games,  Stamps,  and  Art 

Your  visit  to  a  zoo  is  an  end  in  itself  because  of  the  pure  pleasure 
it  yields  in  direct,  enjoyable  experience.  Yet  such  visits  can  take 
on  lasting  meaning  in  a  child's  life  if  you  can  unobtrusively  asso- 
ciate each  animal  with  its  natural  home.  In  this  way  the  child's 
mind  forms  a  clear  idea  of  the  wildlife  of  different  countries  and 
continents.  Some  zoos  group  the  animals  in  exhibits— such  as  the 
Plains  of  Africa— where  mammals  that  are  natural  neighbors  are 
seen  together;  but  in  many  zoos  it  is  necessary  to  point  out  these 
associations  yourself. 

Of  course,  the  how  and  the  when  of  imparting  such  information 
will  depend  on  the  child's  age  and  interest  and  receptivity.  The 
best  method  is  doubtless  one  that  involves  some  active  participa- 
tion by  the  child.  Keeping  a  scrapbook  of  animal  pictures  is  fun 
at  almost  any  age,  and  it  provides  a  good  starting  point  for  talking 
and  learning  about  animals. 

Mammal  Maps 

Most  children  are  fascinated  by  a  map  that  pictures  a  con- 
tinent in  outline  with  its  animals  or  plants  shown  in  the  approxi- 
mate area  where  they  are  most  commonly  found.  Elaborate  maps 
of  this  kind  are  available;  but  children  will  enjoy  making  simple 
maps  of  their  own— perhaps  after  an  expedition  to  the  zoo— which 
will  mean  more  to  them  because  they  have  created  the  maps  them- 
selves. 

Animal  Lotto 

One  of  the  pleasantest  ways  for  very  young  children  to 
become  familiar  with  animals  is  to  play  games  involving  them, 
such  as  Animal  Lotto.  In  this  game  more  than  fifty  mammals, 
with  identifying  names,  are  pictured  on  master  cards;  the  players 
try  to  match  them  by  drawing  individual  pictures  of  the  animals 
from  the  "stock  pile." 

Place  Cards  for  Parties 

For  a  four-year-old's  birthday  we  used  an  idea  for  place 
cards  which  enabled  the  youngsters  to  seat  themselves  without 
assistance.  From  colored  cardboard  we  cut  silhouettes  of  elephants. 


136  ]  Animals  in  the  Wild 

kangaroos,  giraffes,  and  other  animals,  in  duplicate.  Each  child  was 
given  one  of  these,  and  the  duplicate  was  set  as  his  place  card  on 
the  table.  When  refreshment  time  arrived,  there  was  much  excite- 
ment over  matching  up  the  animals,  and  the  children  had  a  happy 
sense  of  accomplishment  in  recognizing  each  silhouette. 

Animals  on  Stamps 

For  older  children  a  stamp  collection  helps  create  a  link 
with  animals  of  the  world;  many  countries  depict  their  character- 
istic and  famous  animals  on  stamps.  The  elephant,  camel,  leopard, 
giraffe,  horse,  tiger  and  antelope  are  but  a  few  of  the  animals 
represented.  A  child's  interest  in  animals  may  create  a  desire  to 
collect  stamps,  or,  contrariwise,  stamp  collecting  may  develop  a 
desire  on  the  child's  part  to  know  more  about  the  animals. 

Animals  in  Art 

The  limitless  field  of  art  suggests  another  way  in  which 
two  different  interests  may  mutually  stimulate  one  another.  Almost 
every  youngster  enjoys  drawing  familiar  animals,  and  many  chil- 
dren favor  some  animal  that  they  will  draw  tirelessly,  again  and 
again.  Aside  from  this,  the  great  world  of  art  opens  up  an 
enormous  field  of  animal  drawings,  pictures,  and  statues  that  will 
delight  children.  Very  often  these  works  of  art  will  impinge  on 
other  interests  of  a  child.  Think  of  the  rock  paintings  of  pre- 
historic man,  Egyptian  sculpture,  Assyrian  reliefs,  Chinese  jade 
figures,  the  art  of  the  North  American  Indians,  the  Aztecs,  the 
Negroes  of  Africa.  All  have  used  animals  in  their  art.  An  interest 
in  art  will  intensify  a  youngster's  interest  in  animals  and  give  him 
a  source  of  lifelong  pleasure.

and  Helpers 


OST  CHILDREN  look  upon  thciT  cats  and  dogs 
as  affectionate  companions,  bound  to  them 
by  strong  ties  of  love  and  loyalty.  On  a  farm,  they  quickly  take 
full  charge  of  colts,  lambs,  calves,  and  kids,  giving  them  infinite 
care  and  consideration.  Young  animals— or  small  ones— seem  to< 
be  a  child's  natural  playmates.  It  often  comes  as  quite  a  surprise^ 
to  a  boy  or  girl  to  learn  that  these  friendly,  docile  creatures  are! 
descended  from  wild  beasts  that  once  feared  man  or  fought  with 
him. 

The  story  of  how  animals  were  tamed  has  been  an  important 
one  to  all  mankind,  not  merely  to  children.  No  one  knows  when 
the  first  wild  animal  was  domesticated.  Certainly  it  was  long;, 
long  ago,  before  the  building  of  the  pyramids.  It  happened  in 
what  we  call  prehistoric  times. 

In  those  times,  our  ancestors  were  mostly  wanderers  on  the 
face  of  the  earth.  Some  had  learned  to  garden  and  raise  crops 
but  others  had  not.  Famine  was  always  at  their  heels.  They  had 
to  be  constantly  on  the  move  in  search  of  the  wild  beasts  from 
which  they  took  their  food  and  clothing.  Stone-tipped  spears, 
bows  and  arrows,  and  crude  axes  were  the  weapons  with  which 
they  fought  for  their  livelihood  in  the  primeval  forest. 

Somehow,  in  some  way,  ancient  man  captured  animals.  Perhaps 
he  started  with  those  that  haunted  the  outskirts  of  his  camp, 
waiting  to  feed  on  his  leavings.  He  tamed  them,  fed  them  and 
bred  them.  Little  by  little,  this  new  practice  of  his  worked  a 
tremendous  revolution  in  his  way  of  life.  Flocks  and  herds  meant 
a  sure  supply  of  flesh  for  food  and  pelts  for  clothing.  With  these 

137 


138  ]  Animal  Friends  and  Helpers 

things  and  garden  crops,  he  could  settle  down  at  last  and  make 
permanent  towns  and  villages.  Civilization,  long  postponed  by 
the  never-ending  quest  for  enough  to  eat,  could  at  last  begin. 

Man  has  not  been  satisfied  merely  to  raise  animals  as  he  found 
them  in  nature.  He  has  carefully  selected  and  mated  stocks,  de- 
veloping in  his  animals  the  qualities  that  serve  him  best.  He  has 
bred  meat  animals  that  give  more  meat,  fur  bearers  that  give 
more  fur.  He  has  created  different  varieties  of  dogs— over  three 
hundred  are  known  today—  for  practically  every  conceivable  pur- 
pose. Still,  if  he  lets  some  of  his  animals  go— cats,  for  example— 
in  a  few  generations  they  become  wild  creatures  again. 

There  is  plenty  of  food  for  thought  and  talk  when  you  take 
your  children  on  a  family  excursion  to  a  farm  and  see  domestic 
animals  in  their  proper  setting,  or  encounter  a  cat,  a  dog,  or  a 
horse  on  city  streets.  Today  they  are  our  friends  and  helpers.  We 
take  them  completely  for  granted.  But  in  a  distant  yesterday, 
they  were  prowlers  and  fighters  whose  conquest  was  one  of  the 
greatest  victories  of  all  time. 

Dogs 

Dogs  are  "sniffers."  They  depend  on  their  sense  of  smell  much 
more  than  on  the  other  senses,  and  with  good  reason.  The  soft 
damp  skin  that  covers  the  dog's  nose  carries  all  scents  to  the  wide 
nostrils,  which  can  be  lifted  in  any  direction.  The  upper  sides 
are  slitted.  This  enables  the  nostrils  to  quiver,  making  them  even 
more  sensitive  to  odors. 

You  will  notice  that  a  dog  investigates  strangers  by  sniffing. 
If  the  scent  he  detects  has  pleasant  associations,  he  accepts  the 
stranger  as  a  friend.  On  the  other  hand,  the  dog  may  immediately 
turn  hostile  if  the  scent  is  distasteful— that  is,  if  it  suggests  a  person 
who  has  been  unkind,  or  perhaps  the  odor  of  another  dog. 

A  dog  will  frequently  rely  on  his  nose  where  another  creature 
would  use  its  eyes.  If  he  loses  something— a  bone,  say,  or  a  toy- 
he  does  not  look  for  it;  he  sniffs  until  he  locates  it.  A  foxhound 
stays  on  the  trail  of  a  fox  for  many  miles,  guided  by  a  scent  which 
may  be  several  hours  old.  This  ability  has  been  put  to  good  use 
in  several  breeds.  An  outstanding  example  is  the  bloodhound. 


Animal  Friends  and  Helpers  [  139 

which  does  an  extraordinary  job  of  tracking  down  lost  or  straying 
people  when  all  other  means  have  failed. 

Your  youngster  will  be  better  equipped  to  take  care  of  his  pet 
if  he  is  aware  that  the  nose  is  an  index  of  well-being.  When  the 
nose  of  a  dog— or  of  any  other  moist-nosed  animal— becomes  dry, 
it  is  a  sure  indication  of  illness. 

Keen  Eyes  and  Ears 

We  admire  a  dog's  eyes  as  "beautifully  soft"  or  "soulful" 
rather  than  "keen."  The  fact  is,  though,  that  dogs  are  sharp- 
sighted,  despite  their  reliance  on  their  sense  of  smell  when  it  comes 
to  locating  misplaced  articles.  Dogs  even  see  fairly  well  in  the 
dark,  though  probably  inferior  to  cats  in  this  respect.  We  have  an 
interesting  contrast  in  breeds  in  the  hunting  dog,  which  stays  on 
an  old  or  recent  trail  guided  solely  by  scent,  and  the  greyhound, 
swiftest  of  all  large  dogs,  which  hunts  by  sight. 

In  most  dogs  the  iris  is  a  rich  brown— though  puppies  usually 
have  blue  eyes— and  the  pupil,  as  in  human  eyes,  is  round. 

There  is  a  considerable  range  of  difference  in  the  shape  and 
appearance  of  the  outer  ears  of  dogs.  This  might  lead  us  to  expect 
a  great  deal  of  variation  in  hearing  ability.  Actually,  however, 
most  breeds  of  dogs  enjoy  an  acute  sense  of  hearing.  Whether  the 
animal  has  long  or  short  earflaps,  the  act  of  "pricking  up  his 
ears"  is  typical  of  an  alert  dog.  As  the  hound  lifts  his  long  ears 
they  form  tubes,  thereby  bringing  sound  more  eflEectively  to  the 
inner  ear. 

Dogs  are  Good  Runners 

Most  dogs  are  strong  runners,  although  running  ability 
varies  quite  a  bit  from  one  breed  to  another.  Dogs  have  long 
muscular  legs  and  when  they  are  running  their  lithe  bodies 
extend  full  length.  The  feet  are  adapted  for  running,  as  they  are 
protected  by  thick  fleshy  pads.  Another  aid  in  running  is  the  fact 
that  the  dog's  claws  do  not  draw  in  as  the  cat's  do;  this  gives  the 
feet  additional  protection. 

The  legs  and  feet  of  dogs  and  cats  have  interestingly  contrasted 
qualities,  for  the  cat  is  a  jumper  rather  than  a  runner.  The  cat's 
legs  are  delicate,  but  its  hips  are  verv  powerful.  These  factors. 


140  ]  Animal  Friends  and  Helpers 

plus  the  lightness  of  its  foot  pads,  make  it  an  admirable  jumper. 
But  the  cat's  claws,  excellent  though  they  are  for  grasping  and 
fighting,  are  pulled  in  and  thus  afford  no  protection  to  running 
feet. 

Dogs  Have  Hearty  Appetites 

Nowadays  we  generally  feed  our  dog  pets  daintily  with  bits 
of  food  cut  up  in  approved  civilized  fashion;  but  they  are  still 
capable  of  gulping  down  large  chunks.  A  friend  of  mine  who  takes 
his  dog  with  him  on  hunting  trips  has  learned  to  be  alert  in 
picking  up  a  rabbit  after  the  kill;  on  several  occasions  the  hound 
arrived  first  and  swallowed  the  rabbit  whole!  Not  only  can  dogs 
swallow  in  bulk;  they  digest  the  food  without  any  trouble. 

Your  child  may  point  to  the  dog  as  an  example  of  why  he 
need  not  chew  his  food.  In  that  case  you  can  explain  the  inter- 
esting difference  in  the  shape  of  the  teeth  which  drastically  alters 
the  case.  Where  we  have  molar  teeth  fitted  for  grinding  (and 
hence  chewing),  the  dog  has  molars  that  are  more  suited  for 
cutting.  Watch  him  work  on  a  bone,  gnawing  first  with  the  back 
teeth  on  one  side  and  then  on  the  other.  His  canine  teeth,  like 
those  of  the  wolf,  are  his  chief  weapons. 

How  Dogs  Talk 

A  dog  has  feelings  of  affection,  anger,  fear,  jealousy,  sor- 
row, and  joy;  he  can  express  all  of  them  by  his  voice.  He  whines 
when  he  is  afraid,  growls  when  angry,  and  sometimes  yips  for 
sheer  joy.  His  bark  is  expressive  of  defiance  or  excitement.  He 
has  still  another  medium  of  expression  in  his  tail:  It  wags  when 
he  is  happy  and  wants  to  express  friendliness,  stands  stiff  when 
he  is  angry,  and  droops  between  his  legs  when  he  is  dejected  or 
ashamed.  Sometimes  in  the  theater  you  see  "talking  dogs"— ani- 
mals that  have  been  taught  to  answer  questions  with  barks  that 
approximate  responses.  Actually  any  intelligent  dog  needs  little 
training  before  you  can  say  of  him,  "He  all  but  talks." 

When  a  Child  Fears  Dogs 

Parents  who  are  dog  enthusiasts  are  often  disconcerted  to 
find  that  their  children  fear  these  animals.  Experiments  tend  to 


Animal  Friends  and  Helpers  [141 

prove  that  a  child's  timidity  with  animals  is  explained  by  some 
prior  unpleasant  encounter,  or  by  his  associating  an  animal  with 
some  frightening  experience— possibly  entirely  unrelated  to  the 
animal.  At  the  same  time  I  cannot  help  also  crediting  a  very 
simple  theory— that  the  generally  unpredictable  actions  of  dogs 
and  their  sudden  movements  are  enough  to  make  some  young- 
sters wary  and  hence  distrustful  of  them.  There  is  also  the  matter 
of  size:  To  a  toddler,  even  a  spaniel  must  appear  as  large  as  a 
lion  does  to  an  adult. 

As  a  very  young  explorer  in  the  world  my  son  had  a  caution 
toward  dogs  and  cats  that  might  have  been  interpreted  as  fear. 
We  had  no  hint  of  any  plausible  reason  for  his  attitude,  but  we 
never  ridiculed  or  lectured  him  about  it.  We  did  give  him  every 
opportunity  to  see  that  we  considered  these  animals  good  friends, 
and  by  the  time  he  was  five  he  wanted  nothing  so  much  as  a  dog 
of  his  own. 

Some  people  believe  that  a  dog,  through  its  sense  of  smell,  or 
some  instinct,  knows  whether  a  person  is  afraid  of  him;  and  that 
the  animal  has  one  attitude  toward  a  brave  soul,  another  toward 
a  timid  one.  Presenting  a  bold  front  is  undoubtedly  the  best 
approach  when  dealing  with  a  strange  or  unfriendly  dog— all  the 
more  so  as  there  is  evidence  to  indicate  that  an  animal  cannot 
detect  well-concealed  fear. 

A  doctor  of  circus  animals  once  confessed  that  throughout  his 
career  he  had  to  struggle  with  actual  terror  whenever  called  upon 
to  treat  a  sick  tiger  or  leopard  or  other  creature  capable  of  great 
violence.  Luckily  he  was  able  to  mask  his  fear  by  keeping  his 
voice  stern  and  his  actions  incisive.  In  this  way  he  remained  master 
of  the  situation.  But,  the  doctor  added,  if  animals  had  any  way 
of  "sensing"  fear  in  a  human  being,  he  would  surely  have  been 
found  out,  and  his  career  ended  before  it  had  fairly  started. 

The  Wild  Strain  in  our  Dogs 

There  Is  a  widespread  belief  that  the  wolf  was  the  dog's 
ancestor,  but  we  now  know  that  this  theory  is  only  partially  cor- 
rect. Dogs  and  wolves  may  have  had  a  common  ancestor  some 
fifteen  million  years  ago,  and  scientists  believe  that  the  four 
earliest  breeds  of  dogs  probably  developed  from  this  animal. 


142  ]  Animal  Friends  and  Helpers 

We  can  clearly  trace  some  of  the  modern  dog's  outstanding 
traits  to  its  wild  ancestors.  When  a  dog  gives  chase,  he  usually 
barks— a  throwback  to  the  wild  pack  that  barked  or  bayed  to 
keep  together  while  hunting.  Similarly,  the  modern  dog's  habit 
of  turning  around  a  number  of  times  before  lying  down  makes 
no  sense  to  us,  but  he  owes  this  characteristic  to  his  distant  ances- 
tors—it was  the  way  they  made  themselves  a  comfortable  place 
for  lying  down  in  brush,  grass,  or  reeds.  Your  dog  gains  nothing 
by  such  actions  in  a  modern  home,  but  he  repeats  them  instinc- 
tively just  the  same.  Sometimes  when  a  dog  is  gazing  at  the  moon 
or  when  he  hears  music  he  will  emit  a  series  of  mournful  howls. 
This  too  may  be  a  reversion  to  the  past— to  the  time  when  the 
"pack**  was  called  together,  perhaps  to  hunt  by  moonlight. 

How  Man  Tamed  the  Dog 

The  friendly  association  of  human  beings  and  dogs  goes 
back  through  countless  ages.  It  must  have  started  in  some  such 
way  as  this:  In  the  course  of  their  hunting  excursions  the  early 
cave  dwellers  found  litters  of  puppies  and  brought  back  the 
appealing  creatures  to  their  primitive  homes.  The  puppies  did 
not  grow  up  wild  like  their  parents—for  they  were  fed  and  shel- 
tered by  people,  and  in  return  defended  their  cave  from  enemies. 
The  cave  was  their  home,  the  humans  were  their  masters. 

Primitive  man  could  not  fail  to  appreciate  the  dog's  keen 
senses  of  smell  and  sight:  He  could  take  the  animal  on  hunting 
trips  to  uncover  game  where  he  himself  might  not  suspect  it 
existed. 

As  the  centuries  passed,  men  gradually  changed  their  way  of 
living.  A  crude  cave  was  no  longer  a  good  home,  and  hunting  was 
no  longer  the  only  means  of  supplying  food  for  the  family.  Yet 
the  desire  to  keep  a  dog  in  the  household  did  not  change.  All 
over  the  world  they  had  become  established  as  friends  and  help- 
ers, and  were  bred  for  all  sorts  of  special  purposes. 

The  ancient  Greeks  bred  dogs  small  enough  to  sit  comfortably 
in  ladies'  laps— with  a  view  to  keeping  the  owner's  stomach  warm! 

In  England  there  was  a  need  for  quite  a  different  kind  of  dog. 
Almost  a  thousand  years  ago  a  breed  was  developed  there  with  a 
retreating  nose,  an  undershot  jaw,  and  menacing  teeth.  It  was 


Animal  Friends  and  Helpers  [  143 

to  become  known  as  the  bulldog,  for  its  special  purpose  was  to 
fight  bulls— a  ferocious  sport  that  enjoyed  great  popularity  for 
hundreds  of  years.  The  peculiar  formation  of  the  bulldog's  snout 
enabled  him  to  breathe  easily  while  biting  and  gripping  a  bull. 

The  Scottish  terrier  is  another  good  example  of  special  breed- 
ing. Its  shaggy  eyebrows  evolved  from  breeders'  efforts  to  provide 
these  small  hunting  dogs  with  protection  against  dirt  as  they  dug 
into  fox  holes  and  carried  out  other  hunting  chores. 

Even  dog  styles  had  a  practical  purpose  at  the  time  of  their 
origin.  Poodles,  used  as  retrievers,  had  wool  left  on  their  chest 
to  protect  them  against  cold  while  the  flanks  were  shaved  to 
streamline  them  for  swimming.  Ear-cropping  became  the  fashion 
in  the  eighteenth  century  to  guard  the  floppy  ears  of  hunting 
dogs  against  being  torn  in  the  underbrush. 

Today,  in  our  highly  mechanical  age,  dogs  are  still  being  bred 
and  trained  for  specific  purposes,  performing  tasks  which  no 
machines  have  been  able  to  take  over.  One  of  the  most  interesting 
ways  to  study  the  specialized  dog  breeds  is  to  read  stories  about 
dogs.  Fortunately  there  is  an  abundance  of  them  that  you  can 
read  together  with  your  child,  who  will  be  delighted  with  them. 
Aside  from  the  ageless  classics,  good  adventure  tales  about  dogs 
are  constantly  being  written. 

The  St.  Bernard 

In  his  Book  of  Famous  Dogs,  Albert  Payson  Terhune  gives 
a  touching  description  of  Barry,  a  St.  Bernard  that  rescued  as 
many  as  forty  travelers  from  death  in  the  snow  during  the  first 
ten  years  of  his  life. 

Until  a  great  tunnel  was  cut  through  the  Alps  in  relatively 
recent  times,  travelers  had  to  make  their  way  on  foot  over  the 
snow-clad  mountain  slopes.  Frequently  they  lost  their  way  or 
were  overtaken  by  a  blizzard.  The  rescue  of  such  unfortunates 
presented  a  baffling  problem,  especially  to  the  monks  of  the 
monastery  of  St.  Bernard  situated  at  the  crest  of  the  mountain 
pass.  We  can  only  guess  at  how  much  these  good  men  of  nearly  a 
thousand  years  ago  understood  of  "natural  history,"  but  we  do 
know  that  they  solved  the  problem  effectively. 

What  they  did  was  to  secure  strong,  oversized  yellowish  dop^s

(whose  ancestors  may  have  come  from  Central  Asia) ,  and  to 
breed  them  carefully  for  many  generations.  This  resulted  in  the 
breed  we  know  as  the  St.  Bernard.  Not  only  are  St.  Bernards  still 
used  in  Europe  to  find  people  lost  in  the  snow  and  bring  them  aid; 
these  dogs  are  beloved  pets  in  many  homes  of  our  own  country. 
Their  gentle  and  benign  character  makes  them  perfect  com- 
panions for  children. 

Seeing  Eye  Dogs 

In  almost  any  city  or  town  in  America  you  may  chance  to 
see  a  remarkable  man-and-dog-team  walking  along  quickly  and 
confidently.  Before  you  are  fully  aware  of  the  implications,  the 
boy  or  girl  with  you  may  exclaim: 

''There's  a  Seeing  Eye  dog!" 

It  seems  incredible  that  up  to  the  last  few  decades  there  were 
no  Seeing  Eye  dogs.  And  there  might  still  be  none  if  not  for  the 
extraordinary  pioneering  work  of  Dorothy  Eustis  a  generation 
ago.  Mrs.  Eustis  happened  to  own  a  particularly  wise  and  faithful 
German  shepherd  dog.  The  animal's  joy  in  serving  his  mistress 
started  her  on  a  long  road  of  research,  breeding,  and  training  to 
develop  superservice  dogs. 

After  establishing  a  school  that  graduated  dogs  thoroughly 
trained  to  work  with  policemen,  help  patrol  penitentiaries,  and 
aid  in  war  maneuvers,  Mrs.  Eustis  carried  on  a  work  that  had 
already  been  started  in  Germany— educating  dogs  to  be  the  "eyes'* 
of  blind  people.  Her  pioneering  eventually  led  to  the  establish- 
ment of  The  Seeing  Eye  organization. 

The  German  Shepherd 

The  chances  are  that  the  Seeing  Eye  dog  you  will  encounter 
on  your  walk  is  a  German  shepherd.  Your  young  companion  is 
likely  to  inquire,  "Are  shepherds  always  used  for  Seeing  Eye 
dogs?" 

As  a  matter  of  fact  they  are  not— though  it  is  true  that  most  of 
the  dogs  graduated  by  The  Seeing  Eye  are  shepherds.  The  ability 
not  only  to  assimilate  education  but  to  use  reasoning  power  as  well 
is  inherent  to  some  degree  in  most  shepherds.  Other  breeds  may 
respond  brilliantly  to  training,  but  there  is  a  difference. 


Animal  Friends  and  Helpers  [  145 

The  French  poodle,  for  example,  one  of  the  outstandingly  in- 
telligent dogs,  has  a  keen  memory  and  is  remarkably  quick.  The 
poodle  could  learn  the  routine  of  guiding  a  blind  person  in  con- 
siderably shorter  time  than  it  takes  the  German  shepherd.  But 
the  poodle  would  then  probably  carry  out  any  command  given 
by  his  master,  regardless  of  consequences.  The  shepherd,  on  the 
other  hand,  makes  his  own  decision— to  hold  back  if  a  "forward" 
command  means  trouble. 

How  Seeing  Eye  Dogs  Are  Trained:  Another  almost  inevitable 
question  is,  "How  are  the  dogs  taught  to  do  their  work?"  This 
query  is  constantly  being  put  to  the  members  of  The  Seeing  Eye 
staff.  A  complete  answer  would  literally  fill  volumes,  but  we  can 
get  some  idea  of  the  thoroughness  of  the  program  from  a  knowl- 
edge of  the  work  and  study  required  to  become  a  teacher  in  the 
organization. 

The  apprenticeship  is  a  lengthy  one.  First  the  newcomer  must 
spend  several  months  working  as  a  kennel  assistant,  feeding  and 
cleaning  the  dogs  and  turning  them  out  to  exercise.  Only  then 
is  he  ready  to  start  primary  work  in  obedience  training.  He  studies 
voice  culture  in  order  to  learn  the  best  inflections  to  use  in 
speaking  to  the  dogs;  he  learns  hand  and  body  movements  that 
supplement  spoken  commands  in  the  early  training  stages. 

Only  after  the  student  teacher  has  mastered  the  technique  of 
command  does  he  start  actual  work  with  dogs— some  of  them 
partly  trained,  others  completely  undisciplined.  His  next  step  is 
to  experience  the  actual  sensations  of  a  sightless  person:  For  a 
month  he  constantly  wears  a  lightproof  shield  over  his  eyes.  He 
is  then  ready  to  work  with  human  pupils. 

A  blind  person  who  is  eligible  for  a  dog-guide  must  live  at 
the  headquarters  of  The  Seeing  Eye  in  Morristown,  New  Jersey, 
during  the  period  of  training  with  the  dog  that  is  to  become  his 
guide. 

As  for  the  training  of  the  dogs,  members  of  The  Seeing  Eye 
staff  will  tell  you  that  their  method  stresses  kindness.  The  prin- 
ciple is  sound  for  training  any  kind  of  dog;  for  kindness  and 
patience  are  the  basic  ingredients  that  spell  success  with  a  German 
shepherd  pup  just  as  much  as  with  your  faithful  old  Rover.

Dogs  in  the  Home 

With  more  than  a  hundred  breeds  to  choose  from,  the 
wise  parent  will  give  careful  consideration  to  the  type  that  is 
best  for  his  household.  In  all  fairness  to  yourself,  your  child,  and 
the  pet,  you  want  to  select  an  animal  that  you  can  take  care  of 
properly  without  overtaxing  your  time,  purse,  or  housing  accom- 
modations. 

Training  a  dog  pet  can  be  a  fascinating  project.  There  is  much 
in  the  training  of  dogs  that  duplicates  the  upbringing  of  a  child! 
Good  health  is  important:  A  tired,  nervous  creature  will  not 
respond  to  the  best  trainer.  Patience,  consistent  rules  and  actions, 
determination— all  these  are  essential  to  successful  training.  Like 
a  child,  the  dog  does  his  best  for  someone  who  understands  him 
and  whom  he  likes. 

The  age  of  a  dog  is  less  important  than  we  are  led  to  believe 
by  the  saying,  "You  can't  teach  an  old  dog  new  tricks."  Nine- 
year-old  dogs  have  been  taught  tricks  and  even  trained  as  depend- 
able hunting  companions.  It  is  true,  however,  that  the  earlier 
training  is  begun,  the  easier  it  is  likely  to  be. 


Cats 

Most  children  love  cats,  and  they  recite  the  nursery  rhyme  "I 
love  little  pussy"  with  genuine  feeling.  But  as  they  grow  older, 
they  find  that  their  feline  companions  have  many  critics  and 
even  enemies.  Some  people  feel  that  cats  should  be  done  away 
with  because,  given  a  chance,  they  kill  birds.  Others,  who  doubt- 
less have  in  mind  abandoned  "strays"  that  try  to  make  a  living 
from  garbage  cans,  claim  that  cats  are  dirty  animals.  Another 
charge  is  that  cats  are  incapable  of  loyalty  and  affection. 

But  cats  have  their  defenders  as  well— many  people  champion 
them  with  fiery  zeal.  And,  as  they  can  prove,  cats  are  devoted  to 
their  masters  if  they  are  treated  kindly.  They  also  render  valuable 
service  in  preying  on  the  rats  and  mice  that  must  be  kept  in 
check.  And  cats  are  wonderfully  adaptable;  if  they  have  to,  they 
can  live  by  their  wits  in  the  manner  of  jungle  beasts,  though 
they  can  be  kept  happy  and  healthy  in  a  city  apartment.

Seeing  in  the  Dark 

The  ability  of  cats  to  see  well  in  the  dark  long  ago  gave 
them  a  touch  of  the  macabre:  People  came  to  associate  them  with 
the  nighttime  activities  of  witches  and  hobgoblins,  particularly 
on  Halloween.  Because  of  this  reputation,  children  are  especially 
interested  to  know  just  how  cats'  eyes  function. 

Back  of  the  eye  is  a  reflecting  surface  which  catches  and  reflects 
any  available  bit  of  light.  The  resulting  glow  enables  the  cat  to 
see  in  situations  where  our  eyes  are  inadequate.  The  startling 
green  glare  given  off  by  a  cat's  eyes  is  due  to  this  reflection,  its 
eye  being  almost  completely  covered  by  the  pupil.  During  the 
day  the  pupil  is  narrowed  down  to  a  mere  slit.  In  adult  cats  the 
iris  is  usually  yellow;  in  kittens  it  may  be  blue  or  green. 

Sensitive  Feelers 

Cats,  like  dogs,  have  moist  noses,  and  their  senses  of  smell 
and  hearing  are  keen.  The  hairs  in  a  cat's  ears,  far  from  being 
obstructions,  are  sensitive  aids  in  catching  sounds.  Cats  can  de- 
tect vibrations  beyond  the  range  of  the  human  ear.  They  are 
often  critical  of  musical  performances,  removing  themselves  as 
far  as  possible  from  shrill  radio  music  or  singing  practice  in  the 
home. 

The  hairs  on  a  cat's  face— its  whiskers— are  also  valuable  as 
"feelers."  A  set  of  whiskers  contains  between  twenty-five  and 
thirty  hairs.  If  you  look  at  them  closely,  you  will  note  that  they 
are  set  in  four  lines  above  and  at  the  sides  of  the  mouth,  where 
they  are  connected  to  sensitive  nerves.  Feelers  are  useful  to 
hunters,  especially  night  hunters,  as  Pussy  is  when  in  its  natural 
state;  the  hairs  supply  information  about  the  underbrush  or  other 
terrain  through  which  the  animal  is  moving. 

The  Cat  as  a  Hunter 

Stalking  and  pouncing  on  prey  come  as  naturally  to  a  cat 
as  breathing.  Where  the  dog  uses  sheer  power  and  speed,  the  cat 
resorts  to  stealth  and  cunning.  Having  discovered  the  haunts  of  a 
possible  victim,  the  cat  crouches  motionless  until  the  right  instant 
to  spring.  The  weight  of  the  marauder's  body  knocks  down  the 


148  ]  Animal  Friends  and  Helpers 

rabbit,  mouse,  or  other  victim— which  the  cat  then  seizes  with 
its  sharp  hooked  claws  and  its  strong  canine  teeth  to  make  the  kill. 
If  you  look  into  Pussy's  mouth  you  can  see  the  equipment  of  a 
real  prowler  of  the  jungle.  There  are  two  big  sharp  tushes  in 
each  jaw.  Its  molars  are  sharp-edged  wedges,  perfectly  adapted 
for  cutting  up  meat.  Its  tongue  is  so  rough  it  can  rasp  juices  from 
meat. 

Under  the  conditions  of  modern  civilization  cats  are  often 
expected  to  be  split  personalities:  alert  hunters  ready  to  pounce 
on  any  rodent  that  shows  itself,  and  at  the  same  time  restrained 
and  even  friendly  neighbors  to  all  birds,  tame  or  wild.  Actually 
cats  are  intelligent  enough  to  refrain  from  molesting  birds  if 
they  are  properly  trained  toward  that  end  while  still  young.  The 
most  successful  training  method  seems  to  be  that  of  association- 
creating  situations  where  the  cat  can  observe  its  mistress  or  master 
being  friendly  with  birds  and  expecting  the  cat  to  help  in  pro- 
tecting them.  Punishment  as  a  means  of  curing  bird-hunting  cats 
is  usually  quite  unsuccessful. 

Cats  are  Model  Mothers 

It  is  a  rare  cat  mother  that  shirks  her  responsibility  to 
her  kittens.  As  a  rule,  even  before  they  are  born  she  shows  her 
solicitude  by  looking  for  a  dark  secluded  spot  for  their  entrance 
into  the  world— just  as  in  the  primitive  state  a  cat  sought  a  dark 
cave  for  the  event.  Though  kittens  are  active  almost  immediately 
after  birth,  they  do  not  start  to  open  their  eyes  until  after  five 
days  or  so.  Within  ten  days  the  eyes  are  fully  open. 

Meanwhile  the  mother  nurses  the  kittens  and  industriously 
washes  them  from  nose-tip  to  tail  with  her  rough  tongue.  She 
allows  them  to  romp  and  play  boisterously— even  to  the  extent  of 
frolicking  over  and  around  her;  but  if  they  go  too  far  she  will 
box  their  ears  soundly. 

When  they  are  older  she  gives  them  lessons  in  hunting,  if 
circumstances  permit,  showing  all  the  tricks  at  her  command  for 
catching  mice  and  other  prey.  She  will  even  instruct  them  in  the 
fine  art  of  backing  down  a  tree  trunk— an  important  accomplish- 
ment for  a  cat.  Instinct  prompts  cats  to  climb,  but  many  a  cat  that 


Animal  Friends  and  Helpers  [  149 

has  had  no  coaching  may  reach  the  top  of  a  tree  and  then  be  too 
terrified  to  descend.  Often  a  fire  company  or  the  S.P.C.A.  must 
come  to  the  rescue! 

Children  and  Cats 

When  a  cat— and  this  is  even  truer  of  a  kitten— is  brought 
into  the  home,  training  is  usually  desirable  in  more  than  one 
respect.  Not  only  must  we  teach  the  little  animal  how  to  fit  into 
the  family  program;  we  also  need  to  instruct  the  children  of  the 
family  how  to  handle  and  treat  their  pet. 

A  frightened  cat  or  one  that  has  been  excited  or  angered  by 
teasing,  may  inflict  serious  scratches  on  a  child.  It  is  not  difficult 
to  teach  even  a  small  child  to  pick  up  a  cat  properly— by  approach- 
ing it  from  the  back  or  side  and  placing  one  arm  under  the  cat's 
forelegs  and  the  other  around  its  body  underneath  the  abdomen. 
The  best  way  to  pick  up  a  little  kitten  is  by  placing  your  hand 
under  its  body.  Grasping  the  scruff  of  its  neck  will  not  hurt  a  cat, 
but  it  is  not  a  sensation  that  the  animal  enjoys;  it  is  best  to  resort 
to  it  only  for  disciplinary  reasons. 

Cat  Language 

Children  will  quickly  learn  something  of  the  cat's  own 
language:  the  happy  purr,  the  soft  mew  of  contentment,  the 
begging  meow  of  hunger,  the  frightened  yowl,  the  shrill  battle 
cry  when  the  cat  is  involved  in  a  fight.  The  cat's  body  is  just  as 
expressive  as  its  voice.  A  lashing  tail  (in  contrast  to  a  dog's  happy 
wag)  is  a  sign  of  angry  excitement.  At  such  times  the  cat's  ears 
lie  back— and  if  it  is  badly  frightened,  its  hair  stands  on  end 
over  its  entire  body  and  tail. 

Where  Cats  Came  From 

Though  we  can  trace  back  the  cat  family  millions  of  years 
to  prehistoric  times,  there  is  much  about  the  ancestry  of  domestic 
cats  that  remains  a  mystery.  Many  conflicting  theories  have  been 
advanced  from  time  to  time  regarding  their  origin. 

The  striped  tabby  pattern  is  a  strong  indication  that  the  fore- 
bear of  our  pets  of  today  was  either  the  European  wildcat  or  the 
African  wildcat,  for  both  of  these  species  have  a  striped  pattern. 


150  ]  Animal  Friends  and  Helpers 

But  which  of  the  two  was  the  original  ancestor  is  a  question  that 
has  been  hotly  debated.  The  most  generally  held  opinion  favors 
the  African  or  Kaffir  cat,  which  was  tamed  by  the  ancient  Egyp- 
tians. For  centuries  the  domestic  short-hair  cats  have  mated 
haphazardly,  and  as  a  result  there  is  more  variation  in  their  size 
and  form  than  in  any  other  breeds. 

Persian  Cats 

The  Persian,  or  long-hair,  cat  is  generally  believed  to  have 
originated  somewhere  in  East  Asia.  Though  its  long  silky  coat 
and  fluffy  tail  give  the  Persian  infinite  grace,  it  is  not  so  lithe  in 
build  as  the  short-hair  cats.  Its  body  and  legs  are  both  short  and 
compact.  "Refined"  seems  the  most  suitable  adjective  for  the 
Persian.  It  is  characteristically  unaggressive,  lofty  in  its  bearing, 
and  has  a  soft,  well-modulated  voice. 

Siamese  Cats 

The  Siamese  cat  is  a  comparative  newcomer  to  America, 
the  first  of  the  breed  having  been  imported  from  England  little 
more  than  fifty  years  ago.  Only  a  few  years  before  that  a  famous 
pair  named  Pho  and  Mia  were  first  brought  to  England  from 
Siam.  The  Siamese  cat  is  distinguished  by  its  form— its  hind  legs, 
being  longer  than  the  front  ones,  give  the  body  a  slight  tilt  up- 
ward from  the  shoulder  to  pelvis,  and  its  head  is  long  and  wedge- 
shaped  with  a  flat  forehead. 

The  Siamese  cat  also  has  a  peculiar  coloration,  which  varies 
with  three  distinctive  types.  The  seal  point  Siamese  has  cream  or 
fawn-colored  body  fur,  with  face,  ears,  legs,  and  tail  a  seal  brown. 
Its  slanted  eyes  are  a  deep  sapphire  blue.  In  the  blue  point 
Siamese,  the  body  color  may  be  cream  or  pale  blue  with  the 
points  (or  markings)  a  deeper  blue.  As  for  the  chocolate  Siamese, 
it  has  a  deeper  body  tone  and  rich  brown  markings. 

The  acrobatic  ability  of  Siamese  cats,  combined  with  their 
great  mischievousness,  gave  rise  to  the  legend  that  their  ancestry 
was  part  monkey.  The  legend  is  completely  fanciful,  but  it  is 
amusing  to  recall  it  as  you  watch  a  Siamese  climbing,  leaping, 
twisting  its  tail  and  in  general  performing  "monkeyshines."

The  Manx 

One  of  the  oddities  of  animal  life  is  the  Manx— a  cat  with- 
out a  tail!  This  breed,  whose  ancestors  hailed  from  the  Isle  of 
Man  in  the  Irish  Sea,  has  a  particularly  mild  and  trusting  nature 
and  as  a  pet  is  especially  easy  to  train  and  manage. 

Pet  Shows  and  Pictures 

Once  your  children  are  interested  in  the  different  breeds  T>f 
cats  and  dogs,  attending  a  pet  show  becomes  a  worthwhile  family 
excursion.  At  such  an  exhibit  you  can  see  fine  specimens  of  many 
breeds  and  observe  the  fascinating  results  of  specialized  training. 
If  you  live  in  a  neighborhood  where  a  number  of  children  own 
dogs  and  cats,  it  is  possible  to  stage  a  strictly  home-style  pet  show 
guaranteed  to  provide  fun  as  well  as  an  added  incentive  for  the 
young  masters  and  mistresses  to  have  their  pets  well  groomed 
and  trained. 

Making  a  cat  or  dog  picture  album  is  an  activity  anyone  can 
enjoy.  It  is  fun  to  watch  the  magazines  for  suitable  pictures,  and 
even  the  youngest  member  of  the  family  can  join  in  the  game. 
The  resulting  album  can  be  either  extremely  simple  or  else 
elaborate,  depending  on  the  amount  of  time  you  can  give  as 
adviser  to  the  "art  and  production  department." 

Horses 

If  there  was  ever  the  possibility  of  a  waning  of  interest  in  horses 
in  this  machine  age  of  ours,  that  prospect  vanished  when  television 
brought  Western  movies  with  their  hard-riding  cowboys  into 
the  home.  Life  on  a  ranch  with  horses  became  the  dream  of  count- 
less city-dwelling  girls  and  boys,  and  children  who  had  the  oppor- 
tunity to  ride  felt  a  new  appreciation  of  that  privilege. 

Fortunately  it  is  not  necessary  to  live  on  a  ranch  to  have  a 
personal  acquaintance  with  horses.  There  are  numerous  farms 
where  we  may  see  different  breeds  of  horses,  and  rodeos  and 
horse  shows  are  held  throughout  the  country.  In  some  cities 
there  are  the  magnificent  steeds  of  mounted  police,  as  well  as 
riding  horses  in  the  parks.  In  at  least  a  few  communities,  the 
plodding  horse  of  the  milkman  still  survives.

Horseback  Riding 

A  resident  of  a  large  city  had  a  young  daughter  who  regu- 
larly "galloped'  rather  than  walked  along  the  street.  This  was  a 
real  worry  to  her  parents,  as  the  girl  had  a  heart  condition  which 
ruled  out  strenuous  activity.  After  many  attempts  to  dissuade  her, 
her  mother  happened  to  ask  why  she  galloped.  Her  daughter's 
answer  was  a  matter-of-fact  "I'm  riding  my  horse."  Mother  and 
doctor  then  got  together  on  the  happy  solution  of  providing 
limited  riding  lessons  which  actually  benefited  the  girl's  health. 

When  a  boy  or  girl  is  given  an  opportunity  to  ride,  an  under- 
standing of  the  background  of  the  horse  is  genuinely  valuable; 
for  some  of  the  animal's  qualities  and  reactions  are  easily  trace- 
able to  its  wild  ancestors.  When  startled,  a  horse  shies  in  the 
way  a  wild  horse  would  from  a  suddenly  discovered  enemy.  The 
wise  rider,  therefore,  speaks  in  a  confident  and  encouraging  voice 
to  his  shying  horse  instead  of  scolding  or  hitting  him. 

When  a  horse  lays  his  ears  flat  back,  it  is  a  warning  that  he  is 
angry.  The  ears  may  also  be  an  indication  of  a  horse's  character. 
The  horse  with  ears  drooped  or  turned  back  is  likely  to  be 
treacherous,  whereas  quick-moving  ears  are  a  sign  of  a  particu- 
larly sensitive  nature.  A  good  horse  has  ears  pointed  upward  or 
forward.  He  also  has  a  broad  space  between  the  eyes,  and  his 
head  is  high  between  the  ears. 

A  Horse's  Teeth  Tell  Its  Age 

The  child  who  feeds  a  horse  discovers  that  it  is  wise  to 
offer  lumps  of  sugar  in  an  open  palm  rather  than  grasped  in  his 
finger  tips.  A  horse  can  crop  grass  even  more  closely  than  a  cow, 
thanks  to  his  large  incisor  teeth.  These  teeth  might  easily  nip 
the  fingers  with  the  sugar. 

It  is  by  these  incisors  that  an  experienced  horseman  can  esti- 
mate the  age  of  a  horse.  As  the  teeth  develop,  annual  growth  rings 
are  formed  in  them.  (The  effect  is  somewhat  like  that  of  growth 
rings  in  a  tree  trunk.)  As  the  teeth  wear  with  age,  these  rings 
become  clearly  visible.  The  time-honored  warning  not  to  look  a 
gift  horse  in  the  mouth  is  based  on  this  revelation  of  the  animal's 
age  by  the  state  of  its  teeth. 


Animal  Friends  and  Helpers  [  i53 

Behind  the  incisors  is  a  bare  space  which  allows  for  the  placing 
of  a  bit,  and  behind  this  are  six  molars  on  each  side  of  each  jaw. 
When  a  male  horse  is  about  three  years  old,  canine  teeth  appear 
behind  the  incisors— four  in  all.  In  a  mare  these  canines  are  gen- 
erally small  or  completely  missing. 

How  Horses  Run 

Would-be  cowboys  and  cowgirls  thrill  to  the  pounding  of 
hoofs  as  horses  gallop  across  the  plains.  They  may  notice  that 
during  a  gallop  the  horse  is  completely  off  the  ground  for  a 
moment  after  each  spring  forward.  The  animal  makes  each  spring 
from  one  of  his  fore  feet  and  lands  on  the  hind  foot  of  the  oppo- 
site side  of  his  body.  Just  before  this  "pair"  of  feet  touches  the 
earth  the  other  two  are  coming  up  again,  so  that  the  body  is  in 
the  air  with  all  legs  bent  beneath. 

When  a  horse  is  walking,  two  or  more  of  his  feet  are  always 
on  the  ground.  The  order  of  their  progression  is  right  hind  foot, 
right  fore  foot,  left  hind  foot,  left  fore  foot.  In  a  canter  the  same 
rotation  of  feet  is  used,  but  the  motion  is  of  course  much  more 
rapid.  When  the  horse  trots,  each  diagonal  pair  of  legs  is  alter- 
nately raised  and  put  forward. 

The  Horse's  Wild  Relatives 

A  well-groomed  horse  is  sleek,  glossy,  and  thoroughly 
"civilized"  in  appearance,  but  an  animal  that  has  been  running 
in  the  pasture  all  winter  long  presents  a  very  different  picture. 
Like  all  wild  horses,  which  grow  a  thick  covering  of  hair  during 
cold  weather,  he  has  a  shaggy  coat.  They  shed  this  hair  in  the 
springtime. 

Wild  horses  still  exist  in  limited  numbers.  These  include  the 
so-called  tarpans  of  Mongolia  and  Central  Asia,  which,  though 
smaller  than  domesticated  horses,  are  strong  and  of  stocky  build. 

There  are  still  herds  of  half-wild  horses  on  our  western  prairies- 
descendants  from  horses  brought  to  Mexico  by  Cortez  and  to 
Florida  by  De  Soto.  Some  of  these  imports  from  Spain  strayed 
from  their  masters  and  roamed  far  and  wide  over  the  new  con- 
tinent. Eventually  members  of  the  two  groups  met  and  mated, 
and  before  long  thousands  of  unbridled  horses  added  a  colorful

note  to  the  American  scene.  Comparatively  few  survive  in  the 
wild  state  today;  and  of  this  remnant,  many  are  captured  by 
ranch  owners,  branded,  and  then  released.  We  generally  speak 
of  these  animals  as  "mustangs." 

As  for  ''broncho,"  this  is  not  a  name  for  a  special  breed,  but 
rather  a  generic  term  applied  to  any  wild  American  horse  that 
is  captured  and  trained  for  man's  use.  Today's  bronchos  are 
usually  born  of  domesticated  horses,  then  turned  loose  and 
allowed  to  run  wild  until  they  reach  the  age  of  usefulness. 

The  African  zebras,  members  of  the  horse  family,  have  resisted 
all  attempts  to  domesticate  them.  By  way  of  contrast  Shetland 
ponies,  which  still  run  wild  on  Shetland  and  other  islands  about  a 
hundred  miles  north  of  Scotland,  are  valuable  pack  animals  and 
trustworthy  pets. 

Where  Horses  Came  From 

The  distribution  of  horses  in  the  modern  world  follows  a 
long  history  of  wanderings  and  migrations.  The  family  started 
in  North  America  with  the  "Dawn  Horse"—the  original  ancestor. 
This  was  a  creature  about  the  size  of  a  fox,  with  several  toes  on 
each  foot.  Over  a  long  period  of  time  gradual  changes  took  place 
in  later  ancestral  horses,  notably  in  the  lengthening  of  the  legs 
and  the  steady  enlargement  and  greater  specialization  of  the 
middle  toe.  At  the  same  time  the  other  toes  grew  smaller  and 
smaller,  finally  vanishing  and  being  replaced  by  the  enormously 
enlarged  middle  toe,  which  had  taken  on  the  proportions  of  the 
hoof  as  we  know  it  today. 

Even  before  the  Ice  Age,  some  of  the  ancestral  horses  had  been 
leaving  North  America  for  other  continents,  and  the  true  horse 
of  the  Ice  Age  migrated  also.  Then,  while  the  branches  that  had 
gone  to  Asia,  Europe  and  Africa  flourished,  the  original  North 
American  family  died  out.  Thus  there  were  no  horses  on  the 
North  Amecian  continent  until  the  Spanish  explorers  brought 
them  back. 

Thoroughbreds  and  Other  Popular  Breeds 
Even  when  many  groups  of  horses  still  lived  in  the  wild 
state,  men  in  diverse  lands  were  busy  breeding  the  animals  for 


Animal  Friends  and  Helpers  [  i55 

specialized  uses.  To  these  efforts  we  owe  such  breeds  as  the  Ger- 
man coach  horse,  the  Belgian  saddle  horse,  the  American  saddle 
horse.  Especially  notable  breeds  were  developed  in  England, 
among  them  the  thoroughbred,  which  became  so  famous  as  a 
horse  of  high  quality  that  people  began  to  use  the  term  incor- 
rectly, saying  "thoroughbred"  when  they  meant  "purebred."  (A 
purebred  animal  is  one  which  has  known  and  recorded  ancestry 
and  represents  but  one  breed.) 

Thoroughbreds  excel  in  running,  and  the  finest  race  horses 
are  of  this  breed.  All  our  thoroughbreds  nowadays  are  descended 
from  three  horses  brought  to  England  more  than  two  hundred 
years  ago— two  of  them  Arabian  steeds,  the  remaining  one 
Turkish. 

Arabian  Horses:  Originally  Arabian  horses  were  creatures  of  the 
desert  and,  as  such,  needed  little  food  and  water.  So  great  was 
the  dependence  of  the  Arabs  hundreds  of  year  ago  on  their 
horses  that  they  bred  the  animals  with  great  care,  raised  them 
virtually  as  members  of  the  family,  and  trained  them  like  chil- 
dren. The  result  after  several  generations  was  one  of  the  most 
remarkable  triumphs  of  domestication— a  truly  great  breed,  out- 
standing in  appearance,  intelligence  and  performance.  Not  the 
least  value  of  the  Arabian  horse  lies  in  its  contribution  to  new 
breeds— the  thoroughbred,  for  example. 

The  Humble  Donkey  and  Mule 

Children  know  donkeys  as  amusingly  stubborn  creatures. 
Though  these  relatives  of  the  horse  often  do  display  rather  diffi- 
cult temperament,  they  are  valuable  as  beasts  of  burden  in  arid 
regions,  and  for  the  breeding  of  mules  (a  mule  being  the  off- 
spring of  a  male  donkey  and  a  mare.)  Donkeys  are  descended 
from  wild  asses  which  were  tamed  and  used  in  Egypt  before  the 
horse  became  domesticated.  In  its  size,  short  hair  and  other  less 
noticeable  features,  an  ass  bears  a  closer  resemblance  to  the  zebra 
than  to  the  horse.  It  even  has  a  tendency  to  show  stripes  on  the 
legs. 

Mules  are  larger  than  donkeys,  and  shaped  more  like  horses. 
Still,  with  their  lon^  ears,  small  hoofs,  and  large  heads,  they  rather 


156]  Animal  Friends  and  Helpers 

resemble  donkeys.  They  are  also  considered  valuable  as  pack 
animals,  being  noted  for  their  sureness  of  foot  and  their  great 
powers  of  endurance.  As  a  rule,  they  cannot  reproduce  their  kind. 

Catde 

About  the  first  thing  a  toddler  learns  about  cattle  is  that  "cows 
say  moo,"  and  that  cows  give  milk.  The  cow  thereupon  becomes 
an  impressive  figure,  milk  being  the  most  important  and  most 
frequent  item  in  a  child's  diet.  Even  a  child  of  five  is  more  likely 
than  not  to  tell  you  gravely  that  "milk  gives  vitamins."  His  older 
brother  is  interested  in  cows  too— but  mainly  because  they  are 
the  pawns  in  our  televised  folklore  of  ranchers  and  rustlers. 

Cows  FOR  Milk 

Man  has  developed  all  the  varieties  of  domesticated  cattle 
from  wild  species  of  Asia  and  Europe.  It  took  many  generations 
of  selective  breeding  to  achieve  such  marvels  as  the  Holstein  cow, 
which  can  produce  its  weight  in  milk  in  two  weeks,  and  the 
Jersey,  which  gives  more  than  five  thousand  pounds  of  rich  milk 
in  a  year!  Other  noted  dairy  breeds  are  the  Guernsey,  Ayrshire, 
and  brown  Swiss  cows. 

There  are  certain  features  by  which  you  can  recognize  a  good 
milch  cow.  These  include:  the  head  high  between  the  eyes,  which 
should  be  clear,  large,  and  placid;  a  large  mouth  with  a  muscular 
lower  jaw;  a  deep  wide  chest,  hips  much  broader  than  the 
shoulders,  and  a  large,  well-supported  abdomen.  As  you  would 
expect,  the  udder  should  be  large  and  its  four  quarters  of  equal 
size. 

Cattle  for  Beef 

Aside  from  the  cattle  bred  for  milk  production  there  are 
the  breeds  designed  as  beef  factories.  Among  the  best  known  of 
these  are  the  Hereford,  Aberdeen- Angus,  Galloway,  and  Short- 
horn. You  can  see  many  contrasts  between  them  and  the  milch 
cows.  The  beef  cattle  are  big  and  full  across  the  back  and  have 
thick,  short  necks.  (You  will  notice  that  the  milch  cow  has  a 
thin,  fine  neck.)  The  shape  of  the  body  is  markedly  different  in 


/inimal  Friends  and  Helpers  [  ^57 

these  groups:  The  milch  cow's  body  is  oval  and  the  outline  of 
her  body  sags  in  front  of  the  hips,  whereas  the  meat  animal  tends 
more  to  a  square-shaped  body  and  its  back  is  straight  from  neck 
to  tail. 

How  Milk  is  Produced 

Most  city  children  do  not  get  to  see  cows  very  often,  so  it 
is  not  surprising  that  they  develop  some  strange  notions  about 
how  cows  give  milk.  For  one  thing,  the  supply  of  milk  seems  as 
constant  as  water  flowing  from  a  tap.  Another  misconception  has 
turned  up  since  the  homogenizing  process  became  widespread; 
many  children  believe  that  milk  is  originally  produced  in  that 
state.  And  I  am  probably  not  the  only  one  who  has  heard  a  small 
child  wondering  what  kind  of  cows  give  chocolate  milkl 

Despite  the  way  in  which  man  has  disrupted  the  animal's  natural 
processes,  a  cow  still  produces  milk  as  nourishment  for  her  own 
offspring.  Her  supply  of  milk  is  of  course  most  abundant  soon 
after  a  calf  is  born.  Under  normal  conditions  she  would  go  dry 
as  soon  as  the  young  one  could  turn  to  other  feeds,  but  a  domestic 
cow  that  is  milked  continuously  may  give  milk  for  almost  a  year. 
The  quantity  decreases,  however,  after  six  to  eight  months,  and 
the  cow  must  be  bred  again  to  renew  the  milk  supply.  A  wise  dairy- 
man does  not  expect  cows  to  produce  constantly,  and  gives  them 
a  rest  of  at  least  six  weeks  every  year. 

How  Cows  Eat 

If  your  child  watches  a  horse  and  cow  grazing,  he  may  ob- 
serve as  he  looks  on  that  the  horse  is  pulling  his  head  in  whereas 
the  cow  is  pushing  her  head  forward.  These  distinctive  eating 
habits  are  no  accident;  they  are  determined  by  each  animal's 
mouth  and  teeth  formations. 

A  cow  has  eight  front  teeth  on  her  lower  jaw,  with  only  a  homy 
pad  above  them.  While  grazing,  she  runs  her  tongue  out,  seizes 
a  clump  of  grass,  and  closes  her  upper  lip  tightly  over  it.  A  for- 
ward thrust  of  her  head  then  causes  the  teeth  below  to  cut  or 
tear  the  grass  from  its  roots.  Thus  she  always  eats  "away  from 
herself." 

The  horse  cannot  gather  grass  with  his  tongue,  but  he  can  use 


158  ]  Animal  Friends  and  Helpers 

his  flexible  upper  lip  to  grasp  it.  He  has  both  upper  and  lower 
teeth  and,  taking  the  grass  between  these  two  rows,  he  cuts  it  by 
pulling  his  head  back.  Thus  a  horse  always  eats  "toward  himself." 
There  is  another  striking  difference  in  the  eating  habits  of 
horses  and  cows.  A  horse  chews  as  it  grazes.  The  cow  uses  a  dif- 
ferent technique,  due  to  the  fact  that  instead  of  one  stomach, 
she  has  four!  She  swallows  the  grass  exactly  as  it  is  cut,  and  the 
unchewed  food  goes  directly  into  her  first  stomach.  Later  the 
food  progresses  to  the  second  stomach,  where  it  is  formed  into 
cud  balls  in  a  convenient  size  for  chewing.  When  the  cow  lies 
down,  this  food  is  brought  back  to  the  mouth.  She  chews  her  cud 
contentedly  with  her  grinding  teeth  until  it  is  ready  to  be  swal- 
lowed. It  then  passes  to  her  third  and  fourth  stomachs,  where  it 
is  digested. 

Mammals  equipped  to  eat  in  this  fashion  are  known  as  "rumin- 
ants." They  include  sheep,  deer,  antelope,  and  camels.  In  the 
wild  state,  the  ruminants'  technique  is  a  definite  protection,  for 
they  can  graze  rapidly  in  the  open  (where  flesh-eating  beasts  might 
prey  upon  them) ,  and  then  retire  to  a  sheltered  area  to  continue 
their  meal  in  comparative  safety. 

How  Cattle  Express  Themselves 

Though  their  domestication  goes  back  through  countless 
generations,  cattle  still  reveal  traces  of  their  wild  ancestry.  Their 
vocal  expressions  are  akin  to  those  of  cattle  still  living  in  the  wild 
state.  The  bull  gives  a  sullen  roar  when  he  is  angry.  The  cow  moos 
gently  to  her  calf,  and  the  lowing  sound  so  characteristic  of  late 
afternoon  in  dairy  farm  country  is  the  call  of  the  herd— the  call 
which  kept  members  of  a  group  together  when  they  were  in  the 
natural  state. 

Though  the  adult  cow  gives  the  impression  of  being  the  most 
phlegmatic  of  creatures,  few  animals  are  more  frolicsome  than  a 
calf.  Even  cows  sometimes  forget  their  dignity,  kicking  up  their 
heels  exuberantly  as  the  tail  is  held  aloft.  In  bulls  the  instinct  for 
battle  is  still  strong.  Those  living  in  the  wild  state  use  their  vicious 
horns  not  so  much  against  other  animals  as  against  rival  bulls 
that  attempt  to  displace  them  as  master  of  a  harem.

Good  Hearers  and  Smellers 

Cattle  have  a  keen  sense  of  hearing,  benefiting  from  the 
fact  that  they  can  turn  their  ears  in  any  direction.  Their  sense 
of  smell  is  also  excellent:  The  moist,  sensitive  nose  is  equally  well 
adapted  for  picking  up  the  scent  of  an  enemy  or  deciding  if  food 
is  properly  edible. 

TAiL-SwrrcHiNG 

As  the  cow  is  such  an  emphatic  tail  switcher,  an  observer 
might  read  into  the  action  those  meanings  which  apply  to  the 
tail  movements  of  a  dog  or  cat.  However,  the  tail  has  nothing  to 
do  with  a  cow's  emotions;  it  is  an  efficient  fly-brush  and  swatter, 
and  without  it  a  cow  would  be  miserably  at  the  mercy  of  these 
ubiquitous  insects. 

Goats— They  Don't  Eat  Cans 

Children  are  usually  amused  as  well  as  impressed  by  the  fact 
that  goats  will  eat  anything,  but  one  young  girl  I  know  was  more 
impressed  than  amused.  Lying  on  the  grass  reading  one  fine  after- 
noon, she  was  so  absorbed  in  her  story  that  she  paid  no  attention 
to  a  gentle  tugging  at  her  braided  hair.  Suddenly  she  realized  that 
a  goat  was  thoughtfully  chewing  one  of  the  braids! 

This  seemingly  fantastic  willingness  to  "try  anything  once"  in 
the  way  of  food  begins  to  make  more  sense  when  a  child  realizes 
that  in  the  wild  state  goats  must  subsist  on  the  most  meager  re- 
sources. As  moss,  lichens,  and  bits  of  vegetation  are  the  best  fare 
tc  be  found  high  on  the  rocky  mountain  slopes  where  goats  live, 
it  is  hardly  surprising  that  they  are  not  very  "choosy"  about  what 
they  introduce  to  their  digestive  systems.  There  is  a  popular 
fallacy  that  goats  eat  tin  cans.  What  they  really  enjoy  eating  is 
the  glue  from  the  paper  labels  on  the  cans. 

Goats  Are  Useful  Animals 

By  means  of  selective  breeding,  man  has  developed  goats 
to  serve  him  in  more  ways  than  one.  He  uses  the  Angora  and 
Cashmere  for  their  hair,  which  is  woven  into  very  fine  fabrics. 
Another  type,  the  short-hair  goat,  yields  a  good  meat  supply,  and 
still  another  group  is  valued  for  its  milk. 


i6o]  Animal  Friends  and  Helpers 

These  three  kinds  of  goats  have  served  people  all  over  the 
world,  and  today  milk  goats  are  found  in  every  part  of  the  United 
States.  Many  belong  to  commercial  dairies,  but  probably  half  of 
our  goat  population  is  made  up  of  "back  yard"  residents.  A  great 
point  in  their  favor  is  that  they  can  eke  out  an  existence  even 
when  the  food  supply  is  at  its  scantiest. 

Goat  milk  is  superior  to  cow's  milk  for  two  reasons:  Goat  milk 
is  digested  more  quickly  and  completely,  and  it  is  safe  without 
pasteurization.  Its  taste,  slightly  different  from  that  of  cow's  milk, 
is  preferred  by  some  people  but  is  displeasing  to  others.  Goats 
do  not  get  tuberculosis  and  they  are  as  nearly  disease-free  as  any 
domestic  animal. 

A  goat  becomes  an  affectionate  pet  if  it  is  well  treated.  When 
a  goat  is  angry,  it  shows  its  feelings  by  shaking  its  head.  It  defends 
itself  by  butting  with  its  head  and  striking  an  adversary  with  its 
sharp  horns. 

Sheep— They  Came  Down  from  Mountains 

Like  goats,  sheep  are  mountain  animals.  Even  when  they  are 
domesticated  they  thrive  best  in  cool  dry  surroundings.  In  the 
wild  state  they  lived  in  less  rugged  localities  than  mountain  goats 
do,  but  on  the  other  hand  sheep  were  able  to  subsist  on  pasturage 
that  was  too  thin  for  cattle. 

The  sheep's  great  wool  coat,  originally  developed  as  a  protec- 
tion against  cold,  has  been  particularly  exploited  in  the  Merino 
breed  of  Spain  which  produces  exceptionally  fine  wool.  In  Eng- 
land, where  mutton  is  a  staple  food,  such  breeds  as  the  Dorset 
and  Shropshire  are  valued  for  their  flesh,  although  their  wool  i? 
also  used  to  good  advantage. 

Obedience  Saves  the  Sheep 

Most  children  are  familiar  with  the  figure  of  speech  that 
puts  people  blindly  following  a  leader  on  the  same  level  with 
*'a  lot  of  sheep."  This  scornful  phrase  implies  that  the  unques- 
tioning obedience  indicates  a  lack  of  intelligence;  yet  in  the  case 
of  sheep  the  instinct  for  following  has  often  saved  their  lives.

MARY  AND  HER  LAMB  HAVE  A  BLEATING  CONTEST 
One  delightful  nature  hobby  that  not  enough  people  hove  discovered  is  taking 
out-of-door  pictures.  Animals  and  children  are  natural  subjects.  But  so,  too,  are

Children  can  begin  a  fascinating  lifetime  hobby  with  a  camera.  A  visit  to  a  zoo 
or  a  farm  provides  exciting  opportunities  for  the  young  photographer.  Later,  birds

is  made  to  feel  the  less  favored.  A  cat  can  also  be  trained  to  treat  birds  as  friends. 


Animal  Friends  and  Helpers  [  i6l 

When  sheep  lived  in  the  wild  state,  they  gathered  habitually 
in  flocks  to  feed,  with  a  sentinel  always  on  guard.  When  this 
leader  spied  an  approaching  enemy  or  picked  up  his  scent,  he 
signaled  with  a  bleat  of  alarm,  then  started  off  with  the  whole 
flock  immediately  at  his  heels.  Over  difficult  terrain,  leaping  from 
precipices  when  necessary,  leader  and  flock  made  their  way  until 
they  reached  a  safe  retreat. 

The  bleating  sound  for  which  sheep  are  noted  is  their  means 
of  keeping  in  touch  with  each  other.  In  time  of  danger  they  are 
silent;  but  they  have  a  special  bleat  when  they  catch  sight  of  an 
enemy  and  another  one  when  they  come  upon  water. 

Sheep  have  keen  senses.  Their  large  ears  move  alertly  toward 
the  direction  of  any  sound.  They  can  pick  up  the  faintest  scent. 
Their  excellent  eyes  alter  according  to  the  light  conditions.  In 
sunshine  the  eye  is  just  a  narrow  slit,  showing  a  yellowish  or 
brownish  iris;  in  a  dim  light  the  pupil  grows  larger  until  it 
absorbs  practically  the  whole  eye. 

How  Sheep  Feed 

The  teeth  of  sheep  and  goats  are  alike.  There  are  six  rear 
grinding  teeth  on  each  side  of  the  upper  and  lower  jaws,  and 
eight  incisors  on  the  lower  but  none  on  the  upper.  Thus  equipped, 
sheep  can  crop  short  grass  close  to  its  roots.  Because  the  close 
cropping  by  sheep  may  ruin  pasture  and  because  sheep  droppings 
render  grass  obnoxious  to  cattle,  sheep  herders  and  cattlemen 
have  had  bitter  conflicts.  In  any  event,  sheep  and  goats  manage 
to  be  well  fed  where  cattle  might  starve.  Man  probably  could  not 
invent  a  more  efficient  self-powered  lawn  mowerl 

Pigs-Smarter  Than  You  Think 

**Dirty  pig!"  exclaims  the  tot  just  learning  the  names  of  animals. 

It  is  a  pity  that  pigs'  habits  are  so  generally  misunderstood,  for 
actually  they  are  rated  with  the  most  intelligent,  valuable,  and 
interesting  of  domesticated  mammals.  The  notion  that  they  enjoy 
filthy  surroundings  is  largely  the  consequence  of  man's  careless- 
ness in  keeping  them. 

The  truth  is  that  a  pig  will  keep  its  own  bed  clean  and  neat 


i62  ]  Animal  Friends  and  Helpers 

under  the  most  discouraging  conditions.  The  wild  hogs  of  India, 
for  example,  make  themselves  quite  respectable  nests  which 
resemble  grass  huts—thatched  on  top  and  with  openings  at  the 
side. 

The  fact  that  pigs  like  to  wallow  in  mud  is  advanced  as  further 
evidence  that  they  like  dirt.  The  real  reason  for  their  wallowing 
is  that  the  pig,  being  only  sparsely  covered  with  hairs  and  bristles, 
is  a  constant  victim  of  flies  and  other  insects.  It  has  no  tail,  as  a 
cow  has,  to  swish  these  tormentors  off,  and  so  its  only  hope  of 
cleaning  itself  free  of  pests  is  to  take  a  mud  bath. 

Your  child  probably  shares  the  general  view  that  the  pig's  nose 
is  singularly  ugly.  Be  that  as  it  may,  the  nose  has  many  uses  and 
is  even  comparable  to  the  elephant's  trunk  in  its  value  to  its 
owner.  The  fleshy  covering  of  the  nostrils  is  a  sensitive-feeling 
organ  which,  especially  in  the  wilds,  aids  the  pig  to  locate  bulbs, 
acorns,  roots,  and  other  foods.  Besides  guiding  the  pig  to  food, 
the  nose  also  serves  as  a  digging  tool.  Bony  plates  under  the  flesh 
give  it  remarkable  strength. 

*Tig  eyes,"  small  but  gleaming,  reflect  a  good  brain,  though 
tame  pigs  rarely  have  a  chance  to  show  how  intelligent  they  are. 
Wild  pigs  have  large  open  ears;  those  of  tame  breeds  vary,  some 
being  sharp  and  forward-opening,  others  lopped.  The  distinctive 
feature  of  the  male  pig's  teeth  is  the  upward  curve  of  its  upper 
canines.  These  tusks,  especially  in  the  wild  boar,  make  formid- 
able weapons. 

Pig  Talk 

Though  the  squeals  and  grunts  of  a  pig  are  anything  but 
musical,  they  are  interestingly  intelligible  to  the  human  ear.  You 
recognize  the  hunger  squeal  easily  enough  by  its  querulous  tone, 
and  the  terrified  squeal  of  fright  is  equally  unmistakable.  It  does 
not  take  you  long  to  distinguish  between  the  grunt  of  well-fed 
satisfaction  and  the  habitual  grunting  that  echoes  wild  animal 
ways.  Continuous  grunting  was  once  the  means  by  which  the 
pig  herd  kept  together.

Pics  Are  Big  Eaters 

Wild  pigs  eat  almost  constantly  when  food  is  available,  stor- 
ing up  fat  to  sustain  them  during  the  winter  months.  Tame  pigs, 
too,  will  eat  almost  anything,  and  they  are  much  more  efficient 
than  other  animals  when  it  comes  to  converting  plant  food  into 
flesh.  In  our  own  country,  meat-producing  breeds  have  become 
more  popular  than  the  lard  hog  breeds  which  inspired  the  old 
rhyme  beginning,  "To  market,  to  market,  to  buy  a  fat  pig."~The 
pure  American  breeds  include  the  black  and  white  Poland  China 
and  the  chestnut  or  reddish  Duroc-Jersey.

ow  DO  THEY  Stay  in  the  water?"  "How  do 
they  breathe?"  "Can  they  hear?"   "How 
long  can  they  live?" 

These  are  but  a  few  of  the  questions  that  will  occur  to  your 
child  as  he  observes  the  goldfish  or  tropical  fish  in  an  aquarium 
at  home  or  elsewhere.  For  fish  are  interesting,  question-provoking 
creatures.  Schools  have  recognized  their  popular  appeal  by  mak- 
ing aquariums  classroom  projects.  Newspapers  have  daily  col- 
umns telling  how  to  take  care  of  tropical  fish;  whole  magazines 
deal  with  the  subject;  and  shows  displaying  the  most  unusual 
kinds  of  fish  are  attended  by  eager  youngsters  as  well  as  grown-ups. 

The  common  goldfish  is  the  most  popular  among  children, 
and  even  a  young  child  can  be  taught  to  care  for  a  few  of  these 
hardy,  handsome  creatures  in  an  ordinary  fish  bowl  before  you 
enlarge  the  collection  with  tropical  specimens. 

So  attractive  are  goldfish  and  the  colorful  natives  of  tropical 
waters,  that  interior  decorators  often  plan  space  for  aquariums 
in  formal  settings  as  well  as  in  recreation  rooms.  But  beauty  is 
by  no  means  the  whole  charm  of  these  creatures.  As  we  watch 
the  fish  behind  glass  walls,  so  tranquil  and  completely  undis- 
turbed by  captivity,  we  have  an  experience  comparable  to  don- 
ning a  diving  helmet  and  going  into  the  sea  to  observe  underwater 
life.  Much  of  what  we  see  and  learn  applies  as  well  to  the  life  of 
fish  which  cannot  be  observed  so  closely. 

Now  for  some  of  the  questions  that  a  youngster,  especially  one 
learning  to  swim,  may  ask  about  fish. 

"How  does  it  just  stay  there}"  he  may  inquire  when  he  sees  a 
fish  motionless  in  the  water.  "Why  doesn't  it  sink  to  the  bottom 
or  come  to  the  top?"

The  Swim  Bladder 

The  ability  of  some  fish  to  stay  quietly  in  one  place  is  due 
to  a  unique  organ  known  as  the  "swim  bladder."  It  is  in  the 
lOrward  part  of  the  body  and  is  filled  with  gas— a  mixture  of 
oxygen  and  nitrogen.  Most  fish  (including  the  goldfish)  that 
have  skeletons  of  true  bone  possess  this  organ;  they  need  very 
little  fin  movement  to  stay  at  a  given  depth.  When  they  die,  their 
bodies  rise  to  the  surface. 

Sharks  and  some  other  kinds  of  fish  have  skeletons  of  gristle. 
They  lack  the  swim  bladder  and  consequently  they  can  remain 
suspended  in  one  position  only  by  continuous  muscular  eflEort. 
When  these  fish  die,  their  bodies  sink  instead  of  rising. 

How  Fish  Breathe 

A  fish  has  very  small  nostrils  which  you  can  see  if  you  look 
closely  on  either  side  of  its  snout.  The  nostrils  lead  to  a  little 
sac  where  the  sense  of  smell  is  located—but  they  have  no  connec- 
tion whatever  with  breathing.  When  you  see  a  goldfish  constantly 
opening  and  closing  its  mouth,  it  is  seeking  air  or  oxygen  and 
not  food.  Though  they  live  in  water,  fish  need  oxygen  just  as 
people  do;  but  they  need  it  in  a  different  form.  Most  fish  "drown" 
in  the  air  just  as  a  human  being  will  under  water  if  he  is  sub- 
merged too  long. 

How  THE  Gills  Work 

Instead  of  breathing  through  nostrils  and  lungs,  a  fish  is 
equipped  to  breathe  with  gills.  You  can  see  its  gill  covers— flat, 
bony  flaps— just  back  of  its  head,  one  on  each  side.  When  the  fish 
opens  its  mouth,  allowing  water  to  flow  in,  the  gill  covers  are 
pressed  against  the  body  so  that  water  will  not  enter  from  behind 
them. 

Then  you  see  the  gill  covers  move  outward  as  the  water  is 
forced  out  through  the  gill  slits  when  the  mouth  closes.  As  the 
water  passes  through,  the  oxygen  that  it  contains  is  absorbed  by 
the  tiny  blood  vessels  making  up  the  gills.  (At  the  same  time 
these  blood  vessels  give  off  carbon  dioxide  and  other  body  wastes.) 
The  new  oxygen  thus  obtained  is  then  circulated  through  the 
body.

What  Fins  Are  For 

As  you  watch  your  goldfish  swimming  you  may  get  the  idea 
that  its  fins  are  an  important  element  in  its  forward  movement. 
And  you  are  right,  though  nowadays  scientists  do  not  attach  as 
much  value  to  the  locomotion  value  of  fins  as  they  once  did. 
Experiments  have  shown  that  a  fish  can  navigate  even  without 
its  fins. 

You  will  note  seven  fins  on  the  common  goldfish.  Just  behind 
its  gill  covers  it  has  a  pair  of  fins  called  the  pectorals.  Farther  back 
is  another  pair  called  the  ventrals— or,  if  quite  far  forward,  called 
the  pelvics.  On  its  back  the  fish  has  a  dorsal  fin,  which  it  some- 
times lifts  and  shuts  down  like  a  fan.  On  the  underside,  toward 
the  tail,  is  the  anal  fin.  Finally,  at  the  end  of  the  tail  is  the  caudal 
fin;  we  often  call  it  the  tail  fin. 

How  Fins  Help  Fish  To  Swim 

How  the  different  kinds  of  fins  aid  a  fish's  movement  de- 
pends on  their  shape  and  location.  The  caudal  or  tail  fin  helps 
the  fish  propel  itself  as  it  presses  its  tail  against  the  water  first  to 
one  side  then  to  the  other.  The  shape  of  this  fin  seems  to  be  re- 
lated to  the  swimming  speed  of  different  species.  On  swift  swim- 
mers, such  as  the  trout,  the  caudal  fin  is  strongly  forked  or 
moon-shaped;  on  slow  swimmers  this  tail  fin  is  blunt  or  rounded. 

The  dorsal  fin  acts  as  a  keel:  It  prevents  rolling.  The  anal  fin 
serves  the  same  purpose  and  in  some  species  it  is  also  used  to  give 
the  fish  a  powerful  upward  sweep. 

Pectoral  fins  appear  to  serve  chiefly  as  brakes  for  fish  with  bony 
skeletons— this  is  particularly  true  of  perch— and  these  fins  also 
have  a  slight  balancing  effect.  In  fish  with  other  than  bony 
skeletons— and  this  makes  an  interesting  contrast— the  pectorals 
have  a  powerful  balancing  action  but  are  of  little  use  as  brakes. 
Sharks,  for  example,  are  apparently  unable  to  make  a  sudden 
stop.  As  for  the  ventral  fins,  they  contribute  further  to  keeping 
the  fish  evenly  balanced. 

The  fins  of  the  common  goldfish  are  by  no  means  standard 
equipment.  Many  fishes  do  not  have  ventrals.  Some,  like  the  cod, 
have  three  dorsal  fins;  others  have  two;  others,  one.  Some  have 
two  anal  fins;  others,  one. 


Fish  and  Their  Fabulous  Neighbors  [  167 

Fascinating  Fins:  Certain  kinds  of  fish  have  fascinatingly  special- 
ized uses  for  one  or  more  of  their  fins.  The  front  ray  of  the  first 
dorsal  fin  of  the  angler  fish  is  perfectly  adapted  as  a  rod  and  lure 
with  which  it  fishes  for  smaller  creatures  to  eat.  A  number  of 
fish  have  fins  modified  into  sucking  pads,  and  some  use  specially 
adapted  pectoral  fins  for  walking  on  the  bottom  of  the  sea— or 
even  on  land! 

Moving  Through  the  Water 

The  fish's  mastery  of  motion  in  the  water  is  wonderful  to 
behold.  It  can  dart  forward  with  tremendous  speed,  starting  from 
a  complete  "standstill";  it  can  progress  a  fraction  of  an  inch  with 
scarcely  a  motion;  it  can  move  straight  up  or  down  or  backward. 
There  are  three  types  of  swimming  motions,  and  most  fish  use 
all  three.  These  are:  a  sinuous  movement  of  the  whole  body,  the 
movements  of  the  fins,  and  the  propulsion  resulting  from  water 
being  shot  through  the  gill  chambers. 


THE  COD-PROLIFIC,  USEFUL,  STREAMLINED 

The  codfish,  which  produces  in  the  neighborhood  of  eight  million  eggs  at  a  time, 
is  the  most  valuable  of  all  fish,  as  far  as  man  is  concerned,  because  of  its  cod-liver 
oiL  The  body  of  the  cod,  b/  the  way,  is  admirably  streamlined  for  speedy  progress 
through  the  water.

Swimming  Speeds:  When  your  child  sees  his  goldfish  cover  the 
length  of  its  aquarium  with  one  quick  swish  of  its  body  in  what 
seems  like  no  time  at  all,  he  may  get  the  impression  that  fish 
always  move  with  notable  speed.  It  is  true  that  many  species 
are  capable  of  extremely  rapid  bursts  of  speed,  but  over  long 
distances  they  average  a  much  slower  rate  of  speed.  Salmon  may 
go  at  a  rate  of  twenty-five  miles  an  hour,  whereas  carp  are  not 
known  to  exceed  seven  and  a  half. 

How  the  Goldfish  Gets  Its  Color 

Goldfish  owe  much  of  their  attractiveness  to  their  golden  sheen. 
**Is  there  really  any  gold  in  a  goldfish?"  a  youngster  looking  at 
his  aquarium  may  ask.  The  goldfish  scales  do  resemble  this  pre- 
cious metal,  but  of  course  there  is  no  trace  of  gold  in  their  shiny 
covering.  Color  in  fish  is  mainly  the  effect  of  pigments  which  for 
the  most  part  are  scattered  in  the  surface  layers  of  the  skin  and 
are  visible  through  the  scales. 

The  ancestors  of  goldfish  were  olive  in  color.  They  belonged 
to  the  carp  family  and  lived  in  the  streams  of  China.  Hundreds 
of  years  ago  some  specimens  were  found  with  golden  tones  on 
their  sides,  and  breeding  was  started  with  these.  The  gold  pre- 
dominated in  some  of  their  offspring,  and  selective  breeding 
continued  until  fish  completely  golden  in  color  were  achieved. 
About  seventy-five  years  ago  a  sailor  brought  back  goldfish  to 
America  from  the  Orient.  They  have  been  popular  pets  here 
ever  since. 

Varieties  of  Goldfish 

Today  we  see  many  fancy  varieties,  such  as  fantail,  fringe- 
tail,  telescope,  and  lion-head.  The  breeding  of  specially  selected 
fish  produces  these  highly  ornamental  creatures,  though  great 
numbers  of  "common"  goldfish  appear  along  with  them.  This 
tyj>e  characteristically  has  a  long  body,  forked  tail,  and  small 
head.  It  may  be  all  gold  or  marked  with  black  and  silver.  It  is 
hardier  than  its  ornamental  relatives  and  if  it  is  transferred  to  a 
pond  with  ample  food,  it  may  grow  to  be  a  foot  in  length. 


Fish  and  Their  Fabulous  Neighbors  [  169 

Fish  Use  Camouflage  Too 

The  color  of  fish  is  often  a  definite  camouflage,  comparable  to 
protective  schemes  on  many  birds  and  mammals.  You  may  see 
a  hint  of  protective  coloration  in  a  goldfish,  as  the  orange  tones 
of  its  back  fade  to  pale  lemon-yellow  below.  In  general,  fish  are 
darker-colored  on  the  back  than  on  the  underside.  As  the  darker 
color  blends  with  the  river  or  pond  bottom,  fish  tend  to  be  less 
noticeable  to  an  observer  from  above.  Yet  when  fish  feed  near 
the  surface  their  light  underparts  blend  with  the  sky,  so  that 
they  are  not  too  likely  to  be  seen  by  enemies  swimming  below. 

Perch,  pike,  and  other  species  that  live  among  weeds  are  pro- 
tected by  their  vertical  stripes.  An  extreme  example  of  camouflage 
is  the  "leaf  fish"  of  the  Amazon  River  which  is  colored  like  a 
dead  leaf  and  has  a  projection  from  its  lower  lip  that  resembles 
a  leaf  stalk.  Even  its  actions  reinforce  the  illusion:  In  stalking  its 
prey  it  drifts  along  like  a  dead  leaf. 

How  Fish  See  and  Hear 

"Goldie  winked  at  me.  I  saw  himl"  my  exuberant  youngster 
exclaimed  one  day  during  a  close  scrutiny  of  the  aquarium. 

He  was  disappointed  when  I  pointed  out  that  a  fish  has  no 
eyelids  and  therefore  cannot  wink.  However,  fish  do  have  eye- 
balls and  when  one  of  these  is  flicked  downward  you  get  the 
impression  of  a  wink.  The  lack  of  eyelids  also  means  that  whether 
the  fish  is  awake  or  asleep,  its  eyes  are  wide  open. 

Fish  do  not  have  keen  sight.  The  part  of  the  eye  that  takes  in 
light  is  round— whereas  in  land  animals  it  is  flattened.  Fish  are 
near-sighted  because  of  the  shape  of  their  eye  lens. 

"Can  the  fish  hear  us?"  is  another  challenging  thought  to 
children  who  enjoy  talking  to  their  charges  at  feeding  time.  It  is 
doubtful  that  they  can,  but  they  do  seem  to  be  awaie  of  hand 
clapping  or  the  sound  of  tapping  on  the  aquarium  walls. 

The  fish  has  no  outside  ear— or  even  openings  where  you  would 
expect  to  find  ears.  It  does  have  other  sense  organs,  however, 
through  which  it  can  get  some  of  the  same  impressions  that  we 
receive  through  our  ears.  In  fact  goldfish,  minnows  and  others 
learn  to  react  to  whistles  and  certain  other  sounds  at  feeding  cime.

Fish  Scales 

The  scales  of  a  fish  look  a  good  deal  like  the  shingles  on  a 
roof.  Each  of  the  scales  grows  separately  from  the  skin,  but  they 
are  set  at  an  angle  so  that  they  overlap  and  form  a  complete  cov- 
ering for  the  body.  Naturalists  sometimes  call  this  scaly  covering 
the  "outside  skeleton." 

Some  fish,  the  catfish  for  one,  do  not  have  scales.  Among  the 
species  that  do  have  scales,  a  newly  hatched  fish  of  the  bony  group 
lacks  the  protection  of  scales  for  its  skin;  but  it  does  not  take  long 
for  them  to  develop.  Some  kinds  of  scales— those  of  the  eel,  for 
example— are  so  tiny  that  you  can  hardly  notice  them.  A  curious 
feature  of  some  members  of  the  tuna  family  is  that  they  are  only 
partly  scale-covered. 

Telung  the  Age  of  Fish 

As  the  fish  grows,  its  scales  grow  too.  You  can  tell  the  age 
of  many  of  the  bony  fish  by  the  markings  on  their  scales;  by  exam- 
ining the  rings  you  can  tell  how  many  birthdays  they  have  passed. 
Of  course  you  will  not  want  to  do  this  with  your  goldfish  pet: 
Its  scales  should  never  be  touched,  let  alone  pulled  out  of  the 
skin.  A  protective  slime  covers  the  scales  and  if  this  is  rubbed  off 
by  dry  hands  or  in  any  other  way,  death  may  result  for  the  fish. 
Children  enjoy  studying  the  scales  cleaned  from  a  fish  destined 
for  the  family  dinner.  Any  youngster  who  knows  how  to  count 
will  get  a  thrill  looking  at  the  scales  through  a  magnifying  glass, 
checking  the  number  and  nature  of  the  rings,  and  reporting  the 
age  of  the  main  course  for  dinner! 

"It  Was  That  Big!" 

Among  fish,  size  is  not  so  standardized  as  among  mammals. 
The  goldfish  is  an  outstanding  case  in  point.  In  an  aquarium  it 
remains  small,  whereas,  given  the  freedom  of  a  pond,  it  increases 
its  size  many  times  over.  Such  factors  as  the  temperature  and 
acidity  of  the  water  and  the  type  of  food  available  limit  the 
length  and  weight  a  fish  can  attain. 

Most  of  the  really  big  fish  are  found  in  the  ocean— though  there 
is  a  huge  species,  the  arapaima,  that  lives  in  the  rivers  of  Brazil 


Fish  and  Their  Fabulous  Neighbors  [171 

and  attains  a  weight  of  four  hundred  pounds.  Among  the  giants 
of  the  sea  is  that  popular  American  food  staple,  the  tuna.  These 
giants  vary  in  size  depending  on  the  regions  to  which  they  are 
native,  but  a  weight  of  a  thousand  pounds  is  about  the  maximum. 
Another  big  fish  is  the  spectacular  swordfish.  Few  sports  are  as 
adventurous  as  deep-sea  fishing,  and  many  a  boy  or  girl,  thrilled 
by  pictures  or  films,  looks  forward  to  taking  a  marlin  or  sailfish 
with  rod  and  reel.  ^ 

Fish  Migrate  Too 

"What  happened  to  the  fish  when  the  water  froze?"  children 
often  ask  as  they  prepare  to  go  skating  over  ice  that  was  a  rippling 
lake  or  stream  only  a  few  weeks  before. 

There  is  more  than  one  answer  to  this  question.  Some  fish— the 
common  sucker,  for  example— burrow  in  the  mud  and  may  be 
frozen  and  thawed  without  being  any  the  worse!  Others  remain 
active  if  the  water  under  the  ice  is  deep  enough.  As  for  carp  and 
some  other  species,  they  move  en  masse  to  deeper  water  at  the 
beginning  of  winter. 

Children  accept  the  seasonal  travels  of  birds  rather  casually 
because  they  can  witness  some  phases  of  their  migrations  each 
year;  but  they  are  likely  to  be  surprised  to  find  that  many  fish 
migrate  too.  Even  their  parents  often  do  not  realize  how  wide- 
spread the  migration  habit  is  among  fish.  Except  for  the  fish  living 
in  ponds,  a  great  many  may  make  migratory  journeys  in  the  course 
of  their  lives.  Sometimes  the  individuals  in  a  traveling  "school" 
are  counted  by  the  million. 

Spawning  Migrations 

Aside  from  the  journeys  of  fish  to  deeper  waters  for  the 
winter,  some  species  of  fresh-water  fish  travel  many  miles  in 
search  of  food.  There  are  also  salt-water  migrations  by  fish  that 
swim  away  from  their  feeding  grounds  to  deposit  their  eggs.  A 
famous  example  is  that  of  the  North  Sea  herring  migrating  in 
the  autumn  to  coastal  waters  off  France.  There  they  spawn  and 
go  northward  again.  When  the  young  hatch  they  swim  to  the 
surface  to  feed  and  are  gradually  swept  north  by  the  main  currents 


172  ]  Fish  and  Their  Fabulous  Neighbors 

until  they  reach  the  North  Sea.  There  are  still  other  migrations 
that  take  fish  from  the  salty  ocean  to  fresh  inland  waters  to  de- 
posit their  eggs. 

How  to  Keep  an  Aquarium  Successfully 

A  home  aquarium  may  be  a  simple  matter  of  keeping  one  or 
two  goldfish  or  it  may  be  a  full-scale  hobby  involving  a  variety 
of  fishes.  Tropical  and  toy  fishes  are  more  difficult  to  raise  than 
the  goldfish,  but  even  this  hardy  pet  requires  certain  favorable 
conditions  in  order  to  survive. 

The  goldfish  needs  adequate  amounts  of  water— about  a  gallon 
for  every  inch  of  fish  in  the  tank.  It  must  be  given  food  in  proper 
amounts;  overfeeding  is  a  far  more  common  trouble  than  insuffi- 
cient food.  The  water  must  be  kept  clean— yet  the  fish  must  not 
be  subjected  to  a  sudden  change  in  temperature  when  fresh  water 
is  provided.  The  tank  must  have  the  right  amount  of  sunlight, 
not  too  much,  not  too  little.  Several  hours  of  hot  summer  sun 
may  kill  the  occupants  of  a  small  tank. 

Plants  are  attractive  in  an  aquarium  and  give  the  fish  a  sheltered 
place  to  rest  and  possibly  to  lay  eggs.  Contrary  to  general  opin- 
ion, they  are  not  essential,  however,  and  too  many  plants  are 
harmful  rather  than  beneficial. 

The  popularity  of  goldfish  has  put  goldfish  breeding  on  a 
substantial  commercial  basis.  A  goldfish  hatchery  near  Frederick, 
Maryland,  covers  150  acres  and  turns  out  about  five  million  fish 
a  year! 

How  Long  Fish  Live 

Properly  cared  for,  the  common  goldfish  may  reach  an 
age  of  twenty-five  or  thirty  years.  Many  species  of  fish  have  a  long 
life  span,  but  in  the  natural  state  they  are  not  likely  to  live  to  a 
ripe  old  age:  They  have  too  many  enemies,  and  some— such  as 
the  Pacific  coast  salmon— die  after  spawning.  However,  records 
of  fish  in  ponds  or  aquariums  tell  us  of  catfish  that  lived  sixty 
years,  halibut  that  rounded  out  thirty,  and  trout  that  flourished 
for  eighteen  years.

Fish  and  Their  Fabulous  Neighbors  [  173 

Fishes  in  the  Brook 

Not  long  after  most  children  learn  the  "little  fishes  in  the 
brook"  rhyme,  they  have  a  strong  desire  to  join  Daddy  when  he 
goes  to  catch  fish.  There  is  something  about  dangling  a  hook  in 
water  and  wondering  what  it  may  bring  up  that  has  a  universal 
appeal  for  youngsters.  If  you  have  access  to  remote  country 
streams  you  have  a  perfect  setting  for  introducing  your  child  to 
the  sport  of  fishing. 

But  even  without  your  efforts  you  may  find  him  tying  a  bent 
pin  to  a  string,  getting  ready  to  try  his  luck  at  a  pond  in  the  park. 
Though  fishing  may  be  inconvenient  to  supervise,  it  is  a  hobby 
well  worth  encouraging.  A  five-year-old  always  seems  to  be  letting 
his  cap  fall  into  the  pond,  with  himself  on  the  verge  of  following 
the  cap.  But  give  him  a  few  more  years  and  the  wholesome  out- 
door sport  of  fishing  is  something  you  and  he  will  be  thankful  for. 

How  To  Plan  A  Fishing  Trip 

When  you  plan  a  fishing  trip  you  can  get  helpful  informa- 
tion from  several  sources:  a  fishing-tackle  dealer,  your  county 
agent,  a  local  game  warden,  or  your  state  fish  and  game  commis- 
sion. You  will  want  to  know  the  lakes  and  streams  where  there 
are  fish,  the  open  season  for  fishing,  the  minimum  size  at  which 
a  caught  fish  may  be  kept,  and  whether  you  need  to  have  a 
license.  Often  a  grown-up  requires  one  but  a  child  does  not. 

More  Fishing  Fun  For  Children 

Children's  needs  have  been  recognized  by  an  organization 
known  as  Better  Fishing,  Inc.,  which  has  arranged  for  them  to 
have  exclusive  rights  to  certain  lakes,  ponds,  and  streams  through- 
out the  United  States.  A  sign,  'Tishing  for  Children  Only," 
marks  these  spots  which  are  reserved  for  fishermen  under  fishing 
license  age.  Sportsmen  in  local  communities  stock  the  waters  with 
trout,  catfish,  bass,  and  pike;  and  many  of  these  people  teach 
children  how  to  fish  and  also  encourage  good  sportsmanship  and 
conservation. 

Better  Fishing,  Inc.*  carries  out  a  nation-wide  program  during 


•Its  headquarters  are  at  509  South  Wabash  Avenue,  Chicago  5,  111.

the  summer  school-vacation  time.  This  is  climaxed  by  a  Boy 
and  Girl  Better  Fishing  Rodeo  Day,  when  prizes  are  awarded 
to  the  boy  and  girl  from  each  participating  municipality  who 
bring  in  the  heaviest  fish.  More  than  three  million  children  have 
thrills  and  fun  in  this  contest  every  year. 

Shiners  and  ^^Pumpkin  Seeds" 

A  Common  Catch 

One  fish  that  father  and  son  are  likely  to  encounter  in  any 
country  stream  is  the  shiner;  this  is  among  the  commonest  of 
little  fish  in  the  brooks  of  America.  It  belongs  to  the  same  family 
as  the  minnow,  and  they  look  very  much  alike,  wedge-shaped  as 
seen  from  above,  rounded  in  front  and  tapering  to  a  point  in 
back.  However,  shiners  are  lighter  in  tone  than  minnows.  A 
delicate  olive-green  covers  the  shiner's  back,  bordered  at  the 
sides  by  a  line  of  blue-purple,  with  a  silvery  sheen  on  the  bottom 
that  seems  to  reflect  the  varied  hues  of  a  rainbow. 

Because  they  are  small,  shiners  are  the  prey  of  many  kinds  of 
fish.  Were  it  not  for  the  countless  eggs  that  this  species  lays,  it 
could  never  survive.  Shiners  live  on  water  insects  and  the  eggs 
of  larger  fishes.  You  are  rather  likely  to  see  them  traveling  in 
schools— a  large  group  of  little  fish  swimming  against  the  current. 

The  Plucky  Sunfish 

Another  attractive  little  resident  of  brooks  and  ponds  is 
the  sunfish  —  known  also  as  "tobacco  box,"  "pumpkin  seed," 
"sunny,"  and  a  variety  of  other  names.  Pumpkin  seed  is  a  good 
description  of  the  fish's  general  form  because,  viewed  from  the 
•side,  its  outlines  strongly  suggest  the  seeds  you  find  when  you 
carve  a  Halloween  jack-o'-lantern. 

Sunfish  are  perhaps  best  known  for  their  gameness:  Though 
small,  they  are  fierce  fighters.  Not  only  do  sunfish  put  up  a  real 
battle  when  caught  on  a  hook— the  males  fight  each  other  to  win 
a  desired  mate.  It  is  not  a  fight  to  the  death,  but  each  fish  tries 
to  mutilate  its  rival's  fins. 

Fishing  for  "sunnies"  with  angleworms  and  any  available  equip 


Fish  and  Their  Fabulous  Neighbors  [  175 

ment  has  always  been  a  popular  sport  for  boys.  Furthermore,  as 
summer  approaches,  sunfish  eagerly  take  a  dry  fly;  fathers  find 
fishing  for  "pumpkin  seeds"  an  excellent  way  of  introducing  their 
sons  to  the  techniques  of  dry-fly  fishing. 

Catching  Pish  for  Observation 

It  is  satisfying  to  catch  fish  for  food  or  for  the  sheer  fun  of  it, 
but  taking  them  for  observation  makes  an  interesting  hobby.  You 
need  a  bar  bless  hook  for  this  purpose,  and  the  simplest  solution 
is  to  file  the  barb  off  a  regular  or  fly-tied  hook.  When  you  catch 
a  fish  of  the  right  size,  remove  it  quickly  with  wet  hands  and  drop 
it  into  a  wide-mouthed  gallon  jar  of  water.  You  can  then  study 
the  actions  of  this  underwater  creature  at  leisure. 

Another  method  is  to  securely  cover  with  wire  mesh  the  top  of 
the  jar  in  which  the  fish  is  captive,  and  place  the  jar  on  its  side  in 
shallow  water  with  about  an  inch  of  air  between  the  water  and 
the  top  side.  Then  you  can  watch  the  fish  for  a  day  or  more;  if 
your  youngster  enjoys  drawing  he  may  wish  to  sketch  the  captive. 

Catching  Fish  With  A  Net 

An  old  and  widely  used  method  is  taking  fish  with  a  net, 
which  you  can  employ  if  it  is  not  against  the  law  in  your  locality. 
A  dark-colored  net,  deep  and  tapering  toward  a  rounded  bottom, 
is  best. 

This  is  how  to  use  the  net:  Walk  into  a  shallow  pond  or  stream 
and  hold  the  net  as  you  would  a  hoe.  Walk  slowly,  keeping  your 
shadow  from  falling  in  front  of  you  and  thus  frightening  the  fish 
away.  When  you  see  a  fish,  twirl  the  net  rapidly  in  the  air  so  that 
the  opening  will  cut  the  water  first.  Then,  with  a  downward 
swoop,  cover  the  fish  and  drag  the  net  briefly  shoreward  along 
the  bottom.  As  you  lift  the  net  from  the  water,  twist  it  again  so 
that  the  opening  faces  upward;  then  immediately  transfer  your 
catch  into  a  jar  or  bucket  of  water. 

Keeping  Records  of  Fish 

Keeping  a  chart  of  fish  found  in  your  region  can  be  as 
rewarding  as  a  bird  or  mammal  record.  To  prepare  a  chart  devoted 


176  ]  Fish  and  Their  Fabulous  Neighbors 

to  fish,  you  can  set  up  five  columns  with  headings  for  name  and 
brief  description,  spawning  grounds,  feeding  grounds,  natural 
food,  and  accepted  bait.  You  may,  if  you  wish,  add  columns  for 
the  date  and  place  of  specimens  caught,  and  another  in  which  a 
small  sketch  may  be  made.  Such  a  chart  is  fun  to  keep  up  and  in 
time  becomes  a  lively  textbook  for  children  in  learning  about 
native  fish. 

Visiting  Fish  Hatcheries 

A  trip  to  a  state  or  national  fish  hatchery  is  entertaining 
and  a  child  can  learn  a  great  deal  from  observing  the  fish  in  all 
stages  of  development  and  discovering  how  streams  and  lakes  are 
stocked.  Most  hatcheries  have  regular  visiting  hours  for  the 
public,  and  if  none  are  located  near  your  home,  you  may  discover 
one  during  a  vacation  trip.  Signs  along  the  highways  will  often 
direct  you  to  hatcheries,  and  a  travel  guidebook  usually  lists  them 
in  the  region  it  covers. 

Family  Life  in  the  Fish  World 

Duels  between  rival  males  are  not  the  only  drama  to  be  observed 
in  the  lives  of  sunfish.  They  belong  to  the  interesting  group  of 
fish  that  make  nests  for  their  families. 

The  male  sunfish  selects  a  spot  in  shallow  water  close  by  the 
shore  and  excavates  mud  and  sand  there  to  make  a  saucer-like 
basin.  He  clears  the  place  of  pebbles  by  jerking  them  away  with 
his  tail  fin  or  by  taking  them  in  his  mouth  and  carrying  them 
away.  Measured  across,  the  finished  nest  is  about  twice  the  length 
of  the  fish. 

The  female  sunny,  recently  won  by  right  of  conquest,  deposits 
her  eggs  in  the  nest  and  then  takes  leave  of  home  and  mate.  But 
the  male  does  not  share  her  irresponsibility.  He  stays  close  to 
the  nest  and  bravely  defends  it  from  enemies  until  the  eggs  hatch. 
Then  the  male  too  resumes  a  carefree  life  so  far  as  his  family  is 
concerned.  There  are  fish  that  carry  parental  duties  still  further. 
The  male  bullhead,  for  example,  continues  to  guard  the  baby 
fish  many  days  after  they  hatch.

THE  SUNFISH  IS  A  SCRAPPER 

Despite  tfs  maximum  length  of  eight  inches,  the  sunfish  leads  a  full  and  adven- 
turous life.  Fierce  and  courageous,  the  moles  fight  duels  during  the  courting  period. 
But  they  also  hove  their  tender  side,  building  nests  and  guarding  the  eggs  after 
their  fickle  motes  depart.  The  sunfish  has  lovely  shimmering  colors  and  is  an 
exceptionally  graceful   swimmer. 

Fish  That  Don't  Lay  Eggs 

Not  all  fish  lay  eggs.  Some  species,  ranging  from  the  great 
tiger  shark  to  the  tiny  guppy,  give  birth  to  young  that  are  in  an 
advanced  state  of  development.  A  guppy  produces  at  least  twenty- 
five  and  perhaps  as  many  as  fifty  offspring  at  a  time;  but  the  parent 
fish  eat  many  of  their  young,  and  only  a  small  proportion  survives. 


Some  Famous  Fish 

Trout— Fisherman's  Favorite 

Trout  live  in  cool  mountain  streams  or  lakes,  where  they 
feed  on  a  variety  of  insects  that  lay  eggs  on  water;  the  trout  also 
greedily  snatch  the  emerging  insects  as  they  hatch.  These  feeding 
habits  make  fly-fishing  for  trout  an  exciting  sport  as  the  fisherman 
lures  his  victim  with  imitations  of  its  favorite  food.  In  small 


178  ]  Fish  and  Their  Fabulous  Neighbors 

streams  trout  rarely  exceed  half  a  pound;  but  in  larger  rivers 
and  lakes  where  food  is  abundant  they  often  reach  from  five  to 
ten  pounds. 

How  Trout  Build  Nests:  One  female  trout  lays  hundreds  of  eggs. 
For  her  nest  she  seeks  water  with  a  gravelly  bottom,  perhaps 
where  the  brook  she  inhabits  flows  into  a  larger  stream.  There 
the  mother  fish  shapes  a  depression  with  her  tail  and  carries  away 
larger  stones  in  her  mouth. 

After  she  has  laid  her  eggs  in  the  nest  and  the  male  has  fertilized 
them,  she  moves  a  little  upstream  and  repeats  the  whole  process. 
The  gravel  and  sand  she  displaces  are  carried  along  by  the  current. 
Most  of  the  discarded  material  is  conveniently  deposited  over  the 
first  nest,  protecting  the  eggs  it  contains.  The  mother  trout  makes 
several  nests  and  lays  eggs  in  all  of  them  before  she  is  finished 
with  the  job. 

Legal  Protection  for  the  Trout:  In  spite  of  the  enormous  quan- 
tities of  eggs  laid  by  trout,  these  fish  were  in  serious  danger  of 
extermination  once  motor  highways  began  opening  wilderness 
country  to  ever-increasing  numbers  of  fishermen.  Aside  from 
being  destroyed  by  their  natural  enemies,  such  as  other  fish  that 
eat  the  eggs  and  young,  the  trout  were  caught  by  these  fishermen 
who  gave  no  thought  to  size  or  season  or  how  many  fish  might 
be  left  in  a  stream. 

The  passage  of  effective  conservation  laws  prevented  the  dis- 
appearance of  trout  from  native  waters  by  regulating  the  seasons 
for  trout  fishing,  the  number  a  fisherman  may  catch  and  the  size 
a  fish  must  be  before  it  can  be  taken. 

Salmon— They  Leap  Waterfalls 

Many  children  have  heard  about  the  travels  of  the  salmon, 
for  this  fish  has  become  a  symbol  of  determination  to  reach  a 
goal.  Pacific  salmon  swim  hundreds  of  miles  to  their  spawning 
grounds  in  North  American  rivers;  the  Atlantic  salmon  go 
hundreds  of  miles  to  reach  theirs  in  rivers  of  Europe  or  of 
America. 

If  you  had  the  opportunity  to  be  at  a  waterfall  where  salmon 
were  making  their  way  upstream,  you  might  see  them  putting 


Fish  and  Their  Fabulous  Neighbors  [  179 

their  noses  out  of  the  swirling  water  as  if  "sizing  up"  the  situation. 
They  turn  their  heads  against  the  falling  water  and  twist  their 
bodies  like  bows,  then  straighten  out  again.  They  bring  every 
muscle  into  play  as  they  try  to  progress. 

Sometimes  they  succeed  by  practically  climbing  the  cascade, 
at  other  times  they  top  it  with  a  single  leap.  No  matter  what  their 
method,  they  never  give  up.  If  need  be,  they  wait  for  days— even 
weeks!— until  a  change  in  the  volume  of  water  provides  a  bettei 
opportunity  to  scale  the  barrier. 

Pacific  salmon  rarely  survive  spawning  to  return  to  the  sea. 
Their  usual  fate  is  to  die  after  breeding. 

Eels— Versatile  Creatures 

"Is  that  a  fish}  Looks  like  a  snake  to  me!" 
With  some  reason  the  children  are  dubious  when  Daddy  dis- 
plays  an  eel  as  the  morning's  "catch."  But  despite  its  elongated, 
snakelike  form  it  is  a  true  fish,  having  gills  for  breathing  and 
fins  for  swimming. 

Eels  and  Snakes:  The  well-known  figure  of  speech,  "slippery  as 
an  eel,"  makes  a  good  point  of  contrast  between  this  fish  and  the 
snake.  The  skin  of  a  snake  is  never  slimy;  that  of  an  eel  is  always 
slimy.  The  eel's  skin  is  thick  and  flexible,  with  the  scales  lodged 
in  it  instead  of  on  the  outside.  Quantities  of  tiny  glands  in  the 
skin  produce  a  sticky  mucus.  These  factors,  combined  with  the 
creature's  suppleness,  give  it  the  ability  to  slip  through  anyone's 
fingers. 

Eels  Love  Privacy:  Eels  live  in  all  kinds  of  waters,  in  mountain 
lakes  and  streams,  in  salt-water  pools  along  the  shore,  and  in 
stagnant  ponds.  Clean  water  or  foul— it  makes  no  difference  to 
the  welfare  of  these  hardy  fish.  It  might  seem  strange,  therefore, 
that  we  do  not  see  them  more  frequently.  The  fact  is,  however, 
that  eels  are  secretive  creatures,  and  much  of  the  time  they  lie 
buried  in  mud.  If  something  seriously  disturbs  them  in  their 
hiding  place,  they  come  out  in  swarms;  they  live  in  groups. 

Vast  Migrations:  Like  salmon,  eels  make  astounding  migratory 
journeys— but  they  reverse  the  salmons'  procedure.   Instead   of 


i8o  ]  Fish  and  Their  Fabulous  Neighbors 

leaving  the  ocean  for  fresh  water,  they  travel  JErom  ponds  and  lakes 
down  rivers  to  the  depths  of  the  ocean— and  there  the  females 
eject  their  eggs. 

The  two  species  of  eel—one  European,  the  other  American— that 
spawn  in  the  same  area  in  the  Atlantic,  travel  in  opposite  direc- 
tions. The  young  whose  parents  come  from  American  rivers  take 
about  a  year  to  travel  from  their  ocean  breeding  place  to  this 
continent;  the  oflEspring  of  European  species  take  three  years  to 
reach  their  destination  in  Europe. 

In  the  course  of  its  travels  the  eel  has  a  notable  advantage  over 
most  fish.  It  has  specialized  gills  that  can  store  a  certain  amount 
of  water.  This  makes  it  possible  for  the  eel  to  leave  a  stream  or 
pond  and  wriggle  over  land  to  another  body  of  water  some 
distance  away. 

Fish  That  Are  Different 

The  Fish  That  Walks 

The  fish  family  has  its  share  of  fantastic  creatures.  In  some 
ways  their  real-life  qualities  are  more  amazing  than  those  of 
mythological  monsters  of  legend  and  myth.  The  climbing  perch 
is  the  commonest  of  these  belie ve-it-or-not  fish.  It  can  survive 
out  of  water  for  several  days,  and  its  pectoral  fins  are  strong 
enough  to  support  its  body  by  acting  as  legs!  This  perch  may  be 
said  to  walk  rather  than  wriggle,  and  it  has  been  found  on  low 
tree  trunks. 

"Flying"  Fish 

Perhaps  more  generally  known  than  the  walking  fishes  are 
those  that  leave  the  water  and  glide  above  its  surface.  If  you  travel 
in  tropical  waters,  such  as  those  around  Bermuda  or  the  West 
Indies,  you  frequently  see  some  of  these  gliders  in  action.  Most 
expert  of  the  group,  the  "flying  fish"  travel  through  the  air  about 
three  feet  above  the  water  at  forty  miles  an  hour,  and  may  go  as 
much  as  four  hundred  yards  at  a  stretch.  All  the  "flying  fish" 
—they  glide  rather  than  fly— live  in  the  ocean,  with  the  exception 
of  one  little  "butterfly"  fish  of  Africa  which  makes  brief  excur- 
sions over  its  fresh-water  home.

A  FISH  OUT  OF  WATER 

One  of  th«  most  remarkable  oddities  of  the  fish  world  is  the  climbing  perch,  which 
can  survive  for  several  days  out  of  water.  Equipped  with  pectoral  fins  that  are 
sturdy  enough  to  act  as  legs,  the  climbing  perch  "walks"  on  land  and  has  even 
been  known  to  climb  low  tree  trunks. 


Sea  Horses— Nature's  Eccentrics 

The  sea  horse,  despite  its  name,  is  a  fish,  and  strictly  a 
swimming  fish  at  that;  but  its  method  of  swimming  is  amusingly 
different.  Children  delight  in  seeing  a  group  of  them  in  a  public 
aquarium,  moving  through  the  water  with  an  appearance  of  great 
dignity— head  upright,  fins  at  the  back.  Any  onlooker  is  bound 
to  be  convulsed  with  laughter  when  the  sea  horse  rolls  its  eyes; 
for  a  sea  horse  can  look  straight  ahead  with  one  eye  and  backward 
with  the  other  at  the  same  time. 

But  these  features  by  no  means  exhaust  the  eccentricities  of 
this  odd  little  fish.  (It  averages  about  three  inches  in  length.)  The 
eggs  of  the  sea  horse  are  incubated  in  a  pouch  that  belongs  to  the 
male— not  the  female.  The  mother  sea  horse  transfers  her  eggs  to 
the  pouch  as  soon  as  they  are  produced;  and  there  they  stay  until 
they  hatch.

THE  SEA  HORSE-AS  ODD  AS  ITS  NAME 

The  ways  of  a  sea  horse  are  strange  indeed.  It  is  a  fish— not  a  horse;  but  it  has 
a  horse-shaped  head  and  a  tail  that  reminds  us  of  a  caterpillar's.  It  swims  upright, 
and  its  eyes  move  independently  of  each  other.  The  eggs  of  the  sea  horse  are 
carried  in  a  pouch— by  the  male!   Bony  plates  cover  the  body  of  this  fish. 


The  dried  bodies  of  sea  horses  are  prize  discoveries  for  boys  and 
girls  at  a  beach,  where  the  animals  are  often  stranded  by  the  tide. 

Shocking  Fish 

Another  unusual  fish  you  may  encounter  at  the  seashore 
is  the  little  electric  star  gazer,  which  spends  much  of  its  time 
buried  to  its  eyes  in  sand.  Only  if  you  happen  to  step  on  one  is 
its  hiding  place  quickly  revealed:  Its  power  to  give  an  electric 
shock  is  its  means  of  defense. 

There  are  other  fish,  larger  than  the  star  gazer,  that  are  also 
equipped  with  "batteries,"  but  they  are  not  native  to  our  country. 
One  of  these  is  the  electric  catfish  of  Africa,  another  the  electric 
eel  of  South  America  which  not  only  uses  its  powers  of  shock  to 
defend  itself,  but  also  as  a  weapon  for  securing  food.

EELS  WITH  BUILT-IN  BAHERIES 

The  electric  eel  of  South  America  carries  a  formidable  electric  charge  with  enough 
current  to  light  several  bulbs.  This  creature,  which  may  reach  a  length  of  as  much 
as  seven  feet  when  full  grown,  uses  shock  tactics  to  immobilize  its  prey,  devouring 
its  victims  at   its  convenience.   It   is  toothless,    so    has  to   swallow   them   whole. 


Just  as  ZOOS  give  you  an  opportunity  to  see  strange  mammals, 
so  public  aquariums  present  some  rare  and  exotic  fishes.  A  trip 
to  one  of  these  aquariums  is  the  best  substitute  for  a  trip 
underseas. 

Sharks— Not  So  Ferocious 

The  "ferocious"  shark,  like  the  pirates  of  old  who  cap- 
tured the  imagination  of  adventure-loving  children,  represents  a 
terrible  menace  of  the  sea.  Any  story  of  shipwreck  immediately 
takes  on  an  element  of  terror  when  "shark-infested  waters"  are 
mentioned. 

Yet  it  is  claimed  sometimes  that  sharks  never  attack  humans 
but  eat  only  small  forms  of  oceanic  life.  If  you  watch  native  boys 
fearlessly  diving  after  coins  tossed  by  tourists  in  the  harbor  of 
Nassau  in  the  Bahamas,  you  may  conclude  that  there  is  a  sound 
basis  for  this  theory.  Frequently  the  fins  of  sharks  which  abound 
in  nearby  waters  may  be  seen  cutting  the  surface  close  by  the 
divers— yet  the  sharks  never  molest  the  boys.  The  probable  ex-

plana tion  is  that  the  noise  and  excitement  and  the  evident  vitality 
of  the  divers  discourage  the  sharks. 

The  "Man-Eater":  Actually  the  biggest  member  of  the  shark 
family,  the  whale  shark,  is  quite  harmless  to  humans,  eating  only 
small  fish,  jellyfish,  and  shell  creatures.  By  way  of  contrast,  the 
great  white  shark,  which  is  found  in  all  warm  seas,  comes  legiti- 
mately by  its  other  name  of  "man-eater":  It  will  devour  almost 
anything  it  can  find,  including  humans  as  well  as  other  sharks. 
The  victim  need  only  be  disabled  or  too  small  to  defend  itself.

Whales— Biggest  Mammals  of  Them  All 

Whales  are  the  biggest  animals  in  the  world.  Fully  grown, 
one  of  them  may  weigh  ten  times  as  much  as  an  elephant!  The 
heroic  whale-hunters  in  the  palmy  days  of  Nantucket  and  New 
Bedford  created  one  of  the  imperishable  epics  of  American  history 
when  they  sailed  the  seven  seas  in  search  of  this  mighty  prey. 

The  enormous  size  of  the  whale  is  bound  to  impress  a  child. 
He  is  likely  to  be  even  more  amazed  when  he  learns  that  whales 
are  mammals— though  they  live  in  water,  as  fish  do.  "How  come, 
then,  that  they're  mammals?"  he  will  surely  demand. 

Whale  "Babies":  One  proof  that  whales  are  mammals  is  the  fact 
that  the  babies  are  born  alive  and  are  nourished  by  their  mother's 
milk.  Whale  calves  are  undoubtedly  the  biggest  babies  produced 
by  any  kind  of  animal,  although  their  size  depends  on  the  size 
and  species  of  the  parent.  Occasionally  it  has  been  possible  to 
record  birth  weights,  and  we  have  a  record  of  an  eighty-foot  blue 
whale  that  bore  a  four-ton  baby!  The  whale  mother  nurses  her 
calf  by  means  of  a  special  compressor  muscle  that  injects  into  its 
mouth  milk  which  looks  exactly  like  cow's  milk. 

Whales  Have  Hair:  Like  land-dwelling  mammals,  whales  are 
warm-blooded;  this  means  that  the  blood  remains  at  pretty  much 
the  same  temperature  regardless  of  how  warm  or  cold  the  animal's 
surroundings  may  be.  But  how  about  the  remaining  test  of  a 
mammal:  Does  the  whale,  with  its  bare  skin,  meet  the  mammal 


Fish  and  Their  Fabulous  Neighbors  [185 

requirement  for  having  fur  or  hair?  Well,  it  does  have  some  hairs 
—just  a  few!— sprouting  under  its  chin.  Its  ancestors  of  long  ago 
doubtless  had  a  great  deal  more  hair. 

How  Whales  Breathe:  But  here  is  another  unorthodox  feature  of 
the  whale.  We  know  that  mammals,  unlike  fish,  do  not  have  gills. 
How,  then,  does  the  whale  manage  to  breathe  in  its  ocean  home? 
Like  the  land  mammals,  it  must  take  oxygen  into  its  lungs. 

This  mammal  of  the  sea  has  nostrils  at  the  top  of  its  head, 
making  possible  a  quick  intake  of  air  when  it  comes  to  the  surface. 
When  the  whale  is  below  the  surface,  special  muscles  close  the 
nostrils  firmly  against  water.  There  is  also  a  passageway  at  the 
back  of  the  mouth  which  directly  connects  the  nose  passage  with 
the  windpipe.  Thus  water  cannot  reach  the  whale's  lungs  even 
when  its  mouth  is  open.  Ordinarily  a  whale  comes  up  for  air  every 
few  minutes;  but  it  can  stay  below  the  surface  twenty  minutes 
or  more  by  making  use  of  oxygen  stored  in  its  blood. 

"There  She  Blows!":  During  an  ocean  voyage  you  might  see  the 
last  phase  of  the  whale's  unique  breathing  operation.  The  excla- 
mation "There  she  blows!"  on  shipboard  calls  attention  to  one 
or  two  fine  sprays,  looking  like  steam  erupting  from  the  water. 
They  indicate  the  spot  where  a  whale  has  just  risen  to  the  surface 
and  exhaled!  The  blast  of  air  sent  out  of  its  nostrils  is  very  warm 
and  saturated  with  water  vapor.  The  blast  condenses  as  it  strikes 
the  colder  air,  forming  the  columns  of  spray  that  have  led  people 
to  insist— incorrectly— that  whales  spout  water. 

How  Whales  Swim:  If  you  are  looking  at  a  picture  of  a  whale 
that  shows  its  whole  body,  it  will  be  interesting  to  see  whether 
your  child  can  notice  an  important  difference  between  the  whale's 
tail  and  the  tail  fin  of  a  fish.  The  former  flattens  out  into  a  broad 
paddle,  lying  in  a  horizontal  plane.  This  is  just  the  opposite  of 
the  fish's  tail,  which  is  always  expanded  vertical-wise.  While  the 
fish  helps  move  itself  forward  by  lashing  its  tail  to  the  right  and 
left,  the  whale  propels  itself  forward  with  an  up  and  down  motion. 

What  Whales  Eat:  After  learning  the  story  of  Jonah  and  the 
whale,  a  child  may  ask,  "Do  whales  really  eat  people?"

THE  BREED  OF  MOBY  DICK 

The  sperm  whale,  with  a  maximum  length  of  sixty  feet  and  a  maximum  weight  of 
sixty  tons,  is  not  among  the  largest  whales!  Its  nose  may  yield  as  much  as  a  ton 
of  spermacetti,  an  oil  which  has  many  uses.  Its  head  is  about  one-third  the  length 
of  its  whole  body.  Moby  Dick  (in  Herman  Melville's  classic)  was  a  sperm  whale. 


Strangely  enough,  this  largest  of  creatures  lives  on  very  small 
animals.  Only  one  species— the  sperm  whale— is  capable  of  swal- 
lowing a  man  whole.  Others  would  be  apt  to  choke  on  any  large 
prey.  The  sperm  whale's  teeth  are  usually  only  on  the  lower  jaw; 
its  diet  consists  chiefly  of  fish  and  squid. 

Of  course,  the  "killer"  whales  and  the  species  known  as  por- 
poises have  teeth;  but  the  largest  whales  are  equipped,  instead, 
with  enormous  strainers.  These  are  made  of  whalebone  plates 
which,  despite  their  name,  are  not  bone  at  all  but  material  re- 
sembling that  of  human  fingernails.  The  whalebone  plates, 
bordered  with  a  horsehair-like  fringe,  grow  from  the  roof  of  the 
mouth.  When  the  whale  swims  with  its  mouth  open,  quantities 
of  shrimp  and  other  small  creatures  are  enmeshed;  when  the 
whale  closes  its  mouth,  the  water  is  forced  out  but  the  victims 
cannot  escape  from  the  trap. 

Mermaids— Glamour  Girls  of  the  Sea 

Fairy  tales,  cartoons,  and  sometimes  decorative  motifs  intro- 
duce most  children  to  the  fantastic,  lovely  ladies  known  as  mer- 
maids. Many  primitive  peoples  the  world  over  have  legends  about 


Fish  and  Their  Fabulous  Neighbors  [187 

mermaids.  Babylonian  art  dating  from  about  1800  B.C.  depicts 
mermaids,  and  only  a  century  ago  Barnum  featured  a  "stuffed 
mermaid"  in  his  side  show!  The  inquiring  mind  of  a  child  plays, 
naturally  enough,  with  the  idea  of  mermaids— even  if  "no  such 
animal"  is  alive  now,  did  it  ever  exist?  If  not,  why  were  mermaids 
"thought  up"? 

The  sea  cow,  a  creature  which,  like  the  whale,  is  a  sea-dwelling 
mammal,  probably  gave  rise  to  the  mermaid  legend.  The  sea 
cow's  head  is  shaped  much  like  that  of  the  seal;  its  body  is  plump 
but  somewhat  fishlike.  Its  startling  feature  is  its  face,  which  sug- 
gests an  oversize,  ugly  human.  It  is  believed  that  when  early 
navigators  saw  sea  cows  raise  their  heads  above  water,  they  were 
struck  by  the  animals'  part  human,  part  fishlike  appearance.  As 
they  did  not  have  binoculars  to  help  them  see  more  clearly,  they 
reported  these  creatures  as  glamorous  mermaids  I 

Sponges 

Boys  and  girls  can  learn  something  of  life  on  the  floor 
of  tropical  seas  by  examining  the  natural  (not  synthetic)  sponges. 
The  sponge,  when  it  is  alive  and  growing  at  the  bottom  of  the 
sea,  looks  more  like  a  plant  than  an  animal.  There  are  many 
varieties  of  sponges,  but  not  all  of  them  are  used  commercially  as 
some  skeletons  are  too  thin  or  scratchy  or  brittle.  Sometimes  the 
skeletons  become  detached  and  float  in  on  a  beach.  However,  the 
sponges  destined  for  commercial  use  are  obtained  by  divers  or 
by  workers  who  pull  them  from  the  ocean  floor  with  tongs  fas- 
tened to  long  poles. 

Corals— Semi-Precious  Ornaments 

Another  sea  animal  that  children  may  know  from  its 
skeleton  is  the  coral.  As  in  the  case  of  sponges,  there  are  many 
varieties  of  corals.  Aside  from  the  type  used  for  making  necklaces 
and  ornaments,  there  are  the  reef-building,  "stony"  kind.  These 
are  responsible  for  the  well-known  coral  isles  of  the  Pacific,  as 
well  as  the  great  coral  reefs  such  as  may  be  found  near  the 
Bahamas  and  off  the  coast  of  Australia.  The  Great  Barrier  Reefs 
off  Australia  are  more  than  a  thousand  miles  long  and  have 
caused  many  a  shipwreck.

Architect  of  the  Seas:  Any  child's  imagination  is  bound  to  be 
stimulated  by  the  amazing  explanation  of  how  the  tiny  soft- 
bodied  coral  polyp  produces  these  gigantic  structures.  A  newborn 
coral  polyp  is  active  at  first  and  swims  freely;  but  soon  it  fastens 
itself  to  a  rock  or  to  the  sea  floor.  Using  carbonate  of  lime  obtained 
from  food  and  water,  it  forms  a  little  platform  under  its  body 
and  a  hard  wall   (called  the  skeleton)  around  itself. 

What  happens  to  most  kinds  of  corals  is  that  these  new  polyps 
remain  attached  to  the  parent  and  in  turn  produce  new  buds. 
As  the  older  ones  die,  young  polyps  build  on  top  of  their  skeletons 
and  thus  the  structure  grows  until  an  island  or  reef  is  formed. 

The  Bashful  Snails 

Observing  a  snail's  daily  activities  need  not  be  the  only 
pleasure  your  child  derives  from  his  unusual  pet.  He  can  also  train 
the  animal  to  be  less  shy.  I  knew  one  friendly  snail  that  would 
come  out  of  its  shell  when  summoned  by  a  sharp  clicking  sound, 
and  would  proceed  to  eat  from  its  owner's  fingers. 

When  a  snail  has  enough  confidence  to  come  out  of  its  shell, 
your  child  will  be  able  to  observe  its  eyes,  which  are  located  at 
the  ends  of  tentacles  attached  to  its  head;  he  can  also  study  the 
horny  jaws  that  cut  up  the  plant  material  it  eats.  If  the  snail  learns 
to  eat  from  his  finger,  he  can  feel  the  tiny  teeth  on  the  tongue 
which  give  it  a  sandpaper  texture. 

How  to  Take  Care  of  a  Pet  Snail:  A  glass  terrarium  furnished  with 
moss  and  ferns  makes  an  excellent  home  for  a  snail.  You  will 
need  a  wire  covering  for  the  enclosure,  as  snails  can  crawl  up  any- 
thing—even a  slippery  piece  of  glass.  They  owe  this  ability  to  a 
substance  they  secrete  as  they  travel.  Snails  require  little  food, 
usually  thriving  on  cabbage  or  lettuce  leaves,  carrot  pulp  and 
the  like. 

At  the  Seashore 

If  you  could  take  your  child  on  an  exploring  trip  around  a 
coral  reef,  you  would  find  many  fantastic  forms  of  life  such  as  the 
giant  plantlike  sea  anemones,  and  such  shellfish  as  the  bright 
pink  crab  that  camouflages  itself  with  bits  of  sponge.  Such  an  ex- 


Fish  and  Their  Fabulous  Neighbors  [189 

pedition  is  out  of  the  question  for  most  of  us,  so  it  is  fortunate 
that  a  number  of  these  tropical  wonders  can  be  seen  much  closer 
to  home— in  tide  pools  along  the  shore,  and  on  rocky  coasts  and 
sandy  beaches. 

Looking  for  these  creatures  and  learning  something  of  their 
way  of  life  can  become  a  delightful  summer  hobby.  You  will  find 
that  a  magnifying  hand  lens  is  a  valuable  piece  of  equipment  to 
help  the  youngster  enjoy  his  discoveries  to  the  fullest.  Children 
of  six  or  over  can  use  a  microscope  to  good  advantage. 

Stinging  Hydroids 

You  can  often  come  across  hydroids  as  you  examine  a  tide 
pool.  These  are  tiny  creatures  that— like  the  giant  sea  anemones 
of  the  coral  reefs— resemble  flowers.  When  they  are  magnified, 
the  hydroids  are  revealed  as  animals.  Like  the  corals,  they  are 
known  as  polyps.  Each  individual  is  attached  to  a  delicate  stalk, 
and  it  has  numerous  threadlike  tentacles  that  are  equipped  with 
stinging  cells.  Small  creatures  that  come  close  are  paralyzed  and 
drawn  into  the  opening  that  serves  the  hydroid  as  a  mouth. 
Many  hydroids  are  quite  transparent,  and  for  this  reason  they 
are  especially  interesting  to  observe. 

Flower-like  Sea  Anemones 

In  the  tide  pools,  too,  you  may  find  sea  anemones,  much 
smaller  than  those  of  tropical  seas  yet  larger  than  the  hydroids. 
When  undisturbed,  they  expand  into  flower-like  forms;  but  the) 
can  contract  quickly  into  an  unattractive  jelly-like  mass.  When 
they  are  in  this  form  you  will  note  their  resemblance  to  jellyfish; 
actually  the  two  animals  are  closely  related. 

Shellfish-They  Aren't  Really  Fish 

A  child  running  barefoot  along  the  seashore  is  likely  to  have 
an  unpleasant  encounter  with  these  creatures,  for  their  sharp 
edges  can  inflict  painful  cuts.  He  soon  learns  to  watch  out  for 
mussels,  clams,  and  all  shellfish  that  are  exposed  to  view  during 
low  tide.  He  will  surely  wonder,  too,  how  these  animals  can  be 
fish  when  they  are  so  different  from  salmon,  trout,  or  other 
''regular"  fish.

SEA  ANEMONES-ANIMALS  OR  PLANTS? 

These  anemones  are  animals,  though  they  look  more  like  plants;  their  "petals" 
are  really  tentacles  encircling  an  odd  sort  of  mouth.  There  are  about  one  thousand 
different  kinds  of  sea  anemones,  some  having  as  many  as  ninety-six  tentacles,  some 
equipped  for  stinging.  If  menaced,  these  queer  creatures  contract  into  a  jelly-like 
mass.  They  have  no  skeletons,  and  are  classed  as  polyps. 

The  fact  is  that  the  term  ''shellfish,"  though  constantly  used, 
is  incorrect;  the  proper  name  for  these  animals  is  "mollusks." 
Every  kind  of  mollusk— there  are  something  like  eighty  thousand 
species!— has  a  soft  body  enveloped  in  a  mantle  which  in  most 
cases  manufactures  or  secretes  a  hard  shell.  There  are  two  siphons 
in  the  mantle;  one  of  them  brings  water  to  the  animal,  the  other 
carries  the  water  away  after  it  has  passed  through  the  gills. 

The  mollusk's  shell  is  sometimes  described  as  a  skeleton— a 
skeleton  without  a  backbone.  Instead  of  being  an  internal  struc- 
ture, the  skeleton  is  carried  on  the  outside  of  the  body.

The  Clam's  Pearly  Lining 

One  of  the  best-known  mollusks,  the  clam,  has  a  shelJ 
made  up  of  three  layers— a  thin  one  on  the  outside,  a  thick  strong 
middle  layer,  and  a  smooth  pearly  lining.  When  a  bit  of  sand  or 
other  foreign  matter  gets  lodged  within  the  shells,  it  becomes 
coated  like  the  lining  and  in  time  may  become  a  true  pearl. 

Squatters'  Rights 

We  find  mollusks  not  only  in  the  sea,  but  in  fresh-water 
lakes  and  streams  and  on  land  as  well.  Some  of  them— the  peri- 
winkle, for  example— have  a  single  shell;  others,  such  as  clams 
and  oysters,  have  two  shells  hinged  along  the  back.  Shellfish  give 
the  deceptive  appearance  of  leading  a  peaceful  existence,  though 
the  fact  is  that  life  is  a  constant  struggle  for  them.  They  are  de- 
voured by  a  variety  of  animals,  and  they  often  vie  with  each  other 
for  living  space. 

Oysters  settle  as  a  rule  in  fairly  deep  water,  though  sometimes  a 
colony  is  located  on  a  mud  flat  that  is  exposed  to  the  air  during 
low  tide.  In  such  a  situation  you  may  see  an  invasion  take  place. 
Mussels,  which  multiply  with  a  great  rapidity,  may  move  in  and 
smother  the  oysters  out  of  existence  by  sheer  weight  of  numbers. 
But,  once  the  mussel  colony  is  established,  it  may  in  turn  be 
invaded  by  a  host  of  barnacles  which  soon  take  over  the  territory 
for  their  own. 

One  of  the  mollusks'  worst  enemies  is  an  innocent-looking  snail 
with  the  sinister  name  of  oyster  drill.  It  plays  great  havoc  in 
oyster  beds  boring  holes  through  the  oyster  shell  and  feeding 
on  the  soft  underlying  flesh. 

The  Self-effacing  Crabs 

You  have  to  keep  a  sharp  lookout  to  catch  a  glimpse  of 
these  notable  creatures  of  the  seashore.  Some  are  expert  at  dis- 
guising themselves  by  putting  seaweed  or  bits  of  sponge  on  their 
back;  some  hide  themselves  almost  completely  in  the  sand  as  they 
lie  in  wait  for  prey;  and  some  are  very  small. 

The  Rock  Crab:  It  should  not  be  too  difficult  to  discover  the

SEASHORE  SCAVENGERS 

Crabs  are  useful  as  scavengers.  They  have  five  pairs  of  legs,  the  front  pair  being 
pinching  claws  for  seizing  food  and  fighting,  the  last  pair  fin-shoped  for  swimming, 
and  the  legs  in  between  adopted  for  walking.  Their  eyes  ore  on  long  stalks  equipped 
with  antennae.  Nature  explorers  young  and  old  find  crabs  fun  to  watch. 


it  is  a  little  over  five  inches  wide,  and  is  commonly  reddish  purple 
in  color.  Like  all  crabs,  the  little  fellow  has  five  pairs  of  legs.  The 
first  pair  are  adapted  as  pinching  claws,  and  in  some  crabs  the 
last  two  pairs,  shaped  like  fins,  serve  effectively  as  swimming  aids. 
It  is  amusing  to  watch  crabs  walk— they  move  sideways  instead 
of  forward  or  backward.  Shore  crabs  are  rather  slow  in  their 
movements;  the  swimming  crabs  are  considerably  more  active. 

Spare  Parts:  If  a  crab  accidentally  loses  a  claw,  it  can  grow  a  new 
one.  During  its  lifetime  it  also  replaces  its  shell,  not  because  of  a 
mishap,  but  because  its  body  gradually  grows  too  big  for  the 
shell.  When  the  original  shell  starts  getting  too  snug,  the  animal 
pulls  itself  free,  and  until  it  grows  a  new  covering  it  is  known 
as  a  "soft-shell"  crab.

THIS  ISN'T  LOVE-IT'S  WAR 

Some  kinds  of  fish  have  a  strong  feeling  of  possessiveness  for  a  certain  territory, 
and  will  savagely  fight  an  intruder.  The  beautiful  Siamese  fighting  fish  is  a  noted 
example  of  this  type.  The  two  shown  here  have  their  jaws  locked  in  combat.  Little 
sunfish,  which  you  may  commonly  find  in  country  streams,  are   also  valiant  fighters.

back  of  its  head  it  is  equipped  with  a  scent  organ  which  it  can  thrust  out  to  produce

The  Aggressive  Lobsters 

If  you  make  a  habit  of  observing  the  activity  among  the 
seaweed  in  shallow  waters,  you  may  have  an  opportunity  to  see  a 
struggle  between  a  lobster  and  a  crab,  although  such  encounters 
are  rather  infrequent.  The  crab— even  a  large  one— apparently  has 
little  chance  against  his  opponent:  A  lobster's  claws  are  extremely 
powerful.  One  of  them  is  very  broad  and  is  used  for  crushing;  the 
narrower  one  cuts  food  to  bits.  Its  mouth  can  crush  as  well  as 
bite.  It  is  also  probable  that  the  lobster  has  an  advantage  over 
the  crab  because  its  feelers,  especially  a  second  pair,  are  longer 
than  the  crab's.  With  them  the  lobster  can  investigate  holes  and 
crevices  and  is  extra-sensitive  to  danger  as  well  as  possible  prey. 


THE  LOBSTER  IS  HELPLESS  WITHOUT  ITS  COAT  OF  ARMOR 

Though  the  lobster  has  a  great  fighting  asset  in  its  brutal  claws,  its  tough  shell  has 
enormous  defensive  value.  At  the  times  when  the  lobster  has  to  shed  its  shell  for  a 
new  one,  it  is  helpless  against  the  onslaught  of  its  enemies.  The  lobster  is  valuable

Shell  Hobbies  Are  Fun 

Shell  Collecting 

Sea  shells  delight  children  who  live  inland  as  well  as  those 
who  have  the  seashore  close  at  hand.  They  may  collect  them  as 
stamps  and  coins  are  collected  through  purchase  at  stores,  by  order 
from  catalogues,  and  through  trading  with  correspondents  the 
world  over. 

Shells  have  a  multiple  appeal.  Some,  such  as  the  giant  conch 
shell,  intensify  the  sounds  they  pick  up  in  their  spiral  interior 
and  thus  bring  to  a  child's  ear  "the  sound  of  the  sea." 

Decorative  Uses  for  Shells 

Shells  have  a  further  appeal  because  you  can  make  art 
objects  with  them.  If  your  child  is  an  enthusiastic  collector,  he 
may  call  on  you  for  ideas  to  put  quantities  of  shells  to  use. 

One  project  that  serves  the  purpose  is  making  shell  book  ends. 
You  start  these  with  two  triangular  blocks  of  wood,  each  attached 
to  a  heavy  wood  base  about  six  inches  square.  Then  you  apply  a 
coat  of  ready-mixed  putty,  nearly  a  quarter  of  an  inch  thick,  to 
the  outer  surfaces  that  are  to  be  decorated.  While  this  is  still 
soft,  press  shells  into  it  just  far  enough  to  be  held  firm.  With 
good  cutting  tools  your  wood  blocks  may  take  varied  shapes, 
while  the  shell  groupings  and  designs  are  limitless  and  the  wood 
and  putty  may  be  painted  as  desired. 

Shell  Handicrafts 

Some  shells  are  suitable  for  making  belts,  necklaces,  brace- 
lets, and  earrings.  A  small  child  needs  help  in  making  the  holes 
where  stringing  is  necessary,  for  shells  crack  easily.  The  most 
effective  way  to  puncture  them  is  with  a  fine-pointed  electric 
drill.  You  can  buy  shellcraft  hobby  packages  in  which  the  pre- 
liminary work  has  been  done;  this  greatly  simplifies  the  assembling 
of  shell  "jewelry." 

A  child  who  gathers  sea  shells  takes  a  far  livelier  interest  in  his 
collection  if  he  thinks  of  a  shell  as  a  fortress  created  by  a  soft- 
bodied  creature.  The  shell  served  the  mollusk  as  a  protective 
covering  during  its  lifetime,  and  after  death  remained  as  a 
memorial  to  the  little  creature  that  lived  in  it. 


CHAPTER  O  Snakes  and  Frogs 
and  Their  Relatives 


HE  CHANCES  ARE  that  snakes  either  fascinate 
you  or  arouse  your  intense  dislike.  Few 
people  are  neutral,  and  children  are  quick  to  adopt  their  parents' 
admiration  or  profound  distaste  for  the  crawling  reptiles.  How- 
ever, some  children  are  so  fond  of  snakes  that  they  will  bring 
them  home  for  pets  regardless  of  how  their  families  receive  the 
creatures.  Under  such  circumstances  one  conscientious  mother 
said  to  me: 

''How  can  I  make  myself  like  snakes?  They  revolt  me,  but  my 
boys  are  always  bringing  them  home  and  have  so  much  fun  with 
them  that  I  don't  like  to  object." 

My  suggestion  was  not  to  try  to  force  a  liking  for  snakes— but 
merely  to  try  to  understand  them.  Snakes  are  probably  the  victims 
of  more  erroneous  beliefs  than  any  other  group  of  animals.  Some 
popular  misconceptions,  and  the  true  facts  about  them,  are: 

1.  False:  All  kinds  of  snakes  are  venomous.  True:  Most  snakes 
are  harmless. 

2.  False:  A  snake  thrusts  out  its  tongue  as  an  act  of  hostility. 
True:  A  snake  uses  its  tongue  as  a  sensory  organ  to  explore  its 
surroundings. 

3.  False:  Snakes  have  no  fear  of  people  and  are  constantly  on 
the  lookout  for  victims.  True:  Most  snakes  do  not  display  an 
aggressive  disposition  toward  people;  if  possible,  they  creep  away 
and  hide  at  a  human's  approach. 

4.  False:  Snakes  can  sting  as  well  as  bite.  True:  No  f^^zLe  can 
inflict  a  sting. 

5.  False:  Snakes  have  great  hypnotic  powers.  True:  Only  the 

195 


196  ]  Snakes  and  Frogs  and  Their  Relatives 

snake's  unblinking  stare,  caused  by  its  lack  of  movable  eyelids, 
gives  us  the  idea  that  it  is  trying  to  hypnotize  its  victim. 

6.  False:  Snakes  spring  from  the  ground  to  attack  a  victim. 
True:  No  snake  jumps  clear  of  the  ground  to  strike. 

7.  False:  Snakes  are  slimy.  True:  Snakes  are  completely  covered 
with  dry  scales. 

8.  False:  Snakes  have  yellow  blood  or  no  blood  at  all.  True: 
Their  blood  is  red  and  practically  the  same  as  that  of  a  mammal. 

When  you  get  to  know  the  truth  about  snakes,  and  understand 
why  they  behave  as  they  do,  you  may  find  yourself  regarding  them 
with  interest  rather  than  horror. 

Reptiles  —  Past  and  Present 

Snakes  are  reptiles,  a  name  scientists  have  given  to  a  group  of 
animals  that  includes  lizards,  turtles,  crocodiles,  and  alligators. 
The  name  was  suggested  by  the  Latin  word  for  * 'creeping." 

Reptiles  were  the  most  important  animals  on  earth  millions  of 
years  ago.  Porpoise-like  species  lived  in  the  ocean  while  batlike 
reptiles  flew  in  the  air.  The  land  was  dominated  by  reptiles  called 
dinosaurs.  At  first  they  were  no  larger  than  rabbits;  later  they 
developed  species  far  bigger  and  heavier  than  the  largest  elephant. 
We  do  not  know  for  certain  why  these  mighty  creatures  dis- 
appeared—changes in  the  earth's  climate  may  have  been  the  cause. 
Whatever  the  reason,  the  importance  of  reptiles  dwindled  and 
warm-blooded  mammals  became  the  outstanding  animals. 

The  Cold-blooded  Snakes 

All  reptiles  are  alike  in  being  covered  with  scales  or  bony 
plates,  and  all  are  cold-blooded.  (They  derive  their  heat  from 
external  sources,  whereas  warm-blooded  animals  derive  theirs 
from  within  their  bodies.)  We  find,  however,  that  reptiles  var^' 
greatly  in  the  way  they  live  and  in  the  places  they  inhabit.  Many 
of  them  dwell  only  in  regions  where  summer  conditions  prevail 
all  year;  but  there  are  some  snakes  that  have  to  adjust  to  a  climate 
with  extreme  variations  of  heat  and  cold. 

Sleeping  Through  the  Winter:  Though  cold  does  not  endanger  a 
snake's  life  until  it  reaches  a  few  degrees  below  freezing,  a  lesser 


SitJi 


Snakes  and  Frogs  and  Their  Relatives  [  ^97 

drop  in  temperature  is  enough  to  cause  sluggishness;  and  a  slug- 
gish snake  does  not  have  the  energy  to  procure  food.  The  solution 
in  cold  climates  is  to  hibernate  in  a  well-sheltered  rocky  crevice 
or  in  the  ground  below  the  frost  line.  In  this  way  the  snake  is 
protected  from  a  fall  in  body  temperature  that  would  be  low 
enough  to  cause  death.  The  animal  can  survive  hibernation 
without  eating,  provided  it  is  in  a  healthy  and  well-fattened 
condition  at  the  beginning  of  its  long  rest. 

The  Snake's  Body—More  than  a  Tail 

Many  children,  and  countless  adults  as  well,  think  of  a 
snake  as  a  long  tail  attached  to  a  head.  This  is  far  from  a  true 
picture— there  is  a  very  efficient  body  between  head  and  tail! 

This  body  contains  a  stomach  capable  of  amazing  distension 
and  digestive  powers,  a  liver,  kidneys,  and  other  organs  too.  The 
snake's  heart  differs  from  a  mammal's  in  having  only  three 
chambers.  (A  mammal's  heart  has  four.)  The  right  lung  is  quite 
elongated,  much  more  developed  than  the  left. 

The  Snake's  Tail 

The  length  of  the  tail  differs  according  to  the  species. 
However,  if  you  scrutinize  a  snake's  underside,  you  will  see  that 
the  tail  has  a  definite  starting  point.  There  a  distinctly  enlarged 
scale— sometimes  divided  into  two  overlapping  parts— covers  the 
orifice  through  which  wastes  pass.  This  marks  the  beginning  of 
the  tail. 

Another  way  of  distinguishing  the  tail  from  the  rest  of  the 
body  in  most  snakes  is  that  the  underside  scales  are  large  and 
each  of  them  extends  across  the  whole  undersurface  of  the  body— 
whereas  the  scales  on  the  underside  of  the  tail  are  almost  always 
arranged  in  two  columns.  A  zoologist  dissecting  a  snake  observes  a 
still  more  obvious  division  of  tail  and  body,  for  the  long  series 
of  ribs  ends  where  the  ribless  tail  begins. 

The  Snake's  Head 

There  are  two  reasons  for  the  snake's  fixed  gaze:  It  has 
no  movable  eyelids,  and  its  eyeballs  are  capable  of  only  slight 


igS  ]  Snakes  and  Frogs  and  Their  Relatives 

motion.  This  results  in  its  "stony  stare"  and  the  false  belief  that 
snakes  hypnotize  their  prey. 

The  Snake's  Hearing  Aid:  Though  snakes  have  no  ears,  they 
might  be  said  to  have  a  sense  of  hearing  as  sounds  are  trans- 
mitted to  them  through  ground  vibrations.  Tests  have  been  made 
with  cobras  to  illustrate  this  point.  After  the  snakes'  eyes  had 
been  bound  with  adhesive  tape,  someone  walked  toward  the 
animals.  Immediately  they  reared  and  faced  in  the  direction  from 
which  the  footsteps  were  approaching.  By  way  of  contrast,  the 
noise  made  by  blowing  a  bugle  brought  no  response. 

This  inability  to  hear  sounds  carried  through  the  air  tends  to 
disprove  the  Hindu  snake  charmer's  claim  that  music  charms 
serpents  into  dancing.  The  truth  seems  to  be  that  the  snakes 
merely  follow  the  continuous  movement  of  the  musician's  arms 
or  knees  as  he  plays  his  reed  instrument. 

You  can  quite  easily  see  the  snake's  nostrils.  There  is  one  on 
either  side  of  the  snout,  and  they  function  in  the  normal  manner. 

Molting— How  Snakes  Shed  Their  Skin 

Your  child  may  be  thrilled  by  the  discovery  of  a  discarded 
snakeskin  in  the  course  of  his  summer  wanderings.  If  he  visits 
the  zoo  he  may  see  just  how  this  molting  takes  place.  The  snake 
loses  its  lustrous  appearance  before  shedding;  its  bright  colors 
are  dimmed.  Even  the  eyes  become  milky  and  the  color  of  the 
eyes  is  obscured. 

This  goes  on  for  a  week  or  two;  then  the  snake's  normal  colora- 
tion returns  and  it  is  ready  to  molt.  It  finds  a  rough,  hard  object 
and  rubs  its  nose  and  chin  against  it  until  its  skin  breaks.  Once 
the  head  is  freed,  the  snake  wriggles  its  body  until  the  whole  skin 
peels  off,  inside  out. 

Why  Shedding  is  Necessary:  Molting  is  necessary  because  the  skin 
to  which  a  snake's  scales  are  attached,  cannot  grow.  After  the  skin 
has  stretched  as  much  as  possible  to  accommodate  the  growing 
snake,  it  must  be  discarded.  Actually  a  new  layer  of  skin  forms 
beneath  the  old  one  before  molting  takes  place.  There  is  no 
regular  interval  for  shedding:  It  depends  to  a  great  extent  on 
the  age  and  vitality  of  the  reptile.  Young  snakes  shed  more 


Snakes  and  Frogs  and  Their  Relatives  [  ^99 

frequently  than  adults,  and  healthy  individuals  more  often  than 
those  in  poor  condition. 

How  Snakes  Move 

If  you  discover  a  snake  on  hard,  packed  soil,  you  will  notice 
that  it  moves  very  slowly.  But  once  it  gets  off  this  smooth  surface 
into  long  grass  or  on  rough  ground,  it  will  whisk  out  of  sight  with 
surprising  swiftness. 

Observe  a  captive  snake  and  you  will  see  the  reason  for  this 
change  in  pace.  When  it  is  placed  on  a  large  piece  of  glass,  it 
will  slip  and  slide  ineffectively;  but  if  it  is  transferred  to  loose 
sand,  it  is  immediately  able  to  make  progress.  This  it  does  with 
sideways  movements,  keeping  the  full  length  of  its  body  against 
the  ground. 

You  will  observe  that  the  creature  leaves  in  its  wake  a  series  of 
slightly  curved  piles  of  sand;  these  prove  to  be  pivots  the  reptile 
has  raised  in  pushing  its  body  forward.  Next  watch  a  snake  on 
rough  grass.  Here  it  will  travel  with  even  greater  ease— each  blade 
of  grass  serves  as  a  pivot. 

"Legs"  Without  Feet:  To  produce  this  undulating  movement— 
apparently  its  most  usual  method  of  traveling— the  snake  depends 
largely  on  its  muscles  and  ribs  which,  in  effect,  are  footless  legs. 
The  ribs  are  attached  to  the  backbone  and  also  to  the  muscles 
and  the  slightly  overlapping  scales  on  the  underpart  of  the  body. 
When  the  muscles  are  moved  forward,  the  scales  are  carried 
forward  also.  When  the  muscles  are  pulled  back,  the  lower  edges 
of  the  scales  press  and  catch  against  any  roughness  on  the  surface 
over  which  the  snake  rests,  and  push  it  forward,  using  the  rough 
spot  for  leverage.  The  snake  does  not  move  muscles  all  along  its 
body  at  the  same  time;  instead,  it  brings  them  forward  gradually, 
and  the  scales  move  in  waves. 

Side-winding:  Another  method  snakes  occasionally  employ  is  to 
curve  the  body  into  an  S  form  and  then  straighten  it  out  again, 
pushing  forward  a  little  in  the  process.  Some  desert  snakes  have 
developed  a  specialized  method  called  "side-winding"  which  is 
practically  indescribable  except  that  the  body  is  thrown  into  great

Snakes  and  Frogs  and  Their  Relatives 


SIDEWINDING  FOR  DESERT  TRAVEl 

Most  snakes  move  forward  with  the  body  flat  against  the  ground.  Not  so  this  desert 
rattler,  which  progresses  in  S-shoped  loops— a  motion  known  as  sidewinding.  This 
is  an  effective  technique  for  crawling  on  sand  and  it  is  used  not  only  by  the 
American  rattler,  but  by  snakes  in  the  deserts  of  Africa  and  Asia  as  well. 

loops  and  seems  to  be  flowing  sidewise.  Using  these  motions  a  snake 
does  not  waste  energy  building  pivots;  yet  it  does  not  slip  back- 
ward. 

Snake  Tracks:  Snakes  leave  trails  in  sand  or  dust  that  are  just  as 
revealing  in  their  way  as  mammal  footprints.  Experts  not  only 
identify  the  kind  of  snake  by  its  trail— they  can  tell  the  approxi- 
mate rate  of  speed  at  which  it  was  moving  when  the  trail  was  made. 

How  Snakes  Breed 

It  is  often  said  that  some  snakes  lay  eggs  while  others  bear 
living  young;  yet  actually  all  species  reproduce  by  means  of  eggs. 
The  difference  between  egg-laying  and  "live-bearing"  consists  in 
this:  The  live-bearing  female  retains  the  eggs  in  her  oviduct 
until  the  embryo  is  fully  developed.  When  the  offspring  are 
"born"  they  are  covered  by  a  thin  membrane  which  soon  bursts. 
Only  about  one-fourth  of  the  known  species  of  snakes  follow  this 
procedure. 

Snake  Eggs 

When  a  female  of  the  other  species  is  ready  to  deposit  her 
eggs,  she  finds  a  sunny  sandbank  or  rotting  log  in  which  to  burrow 
a  hole.  There  she  lays  her  eggs— the  number,  size,  and  shape 


Snakes  and  Frogs  and  Their  Relatives  [  201 

depend  on  the  species.  Usually  they  are  elliptical,  with  flattened 
ends..  When  first  laid,  the  eggs  are  covered  with  a  moist  and  sticky 
skin  which  gradually  becomes  tough  and  leathery.  They  absorb 
water  and  thus  continue  to  grow  after  leaving  the  mother's  body 
until  they  have  increased  about  one-third  in  size. 

The  Egg-tooth 

Projecting  from  the  middle  of  the  upper  jaw  of  the  full- 
grown  embryo  is  an  egg-tooth  with  which  it  slits  the  tough  egg 
skin  when  it  is  ready  to  emerge  as  a  perfectly  formed  young  snake. 
If  you  rub  your  finger  over  the  nose  of  a  baby  snake  you  may  feel 
this  egg-tooth,  which  remains  until  the  baby  is  about  a  week  old. 

How  Snakes  Kill 

It  may  well  be  that  the  horror  snakes  arouse  in  many  people 
is  evoked  by  their  methods  of  killing.  A  tiger's  prey  is  just  as  dead 
as  a  snake's  victim;  but  constriction  and  poison  somehow  seem 
more  sinister  means  of  inflicting  death  than  fang  and  claw. 

Snakes  get  their  food  in  three  different  ways.  For  the  first  and 
most  primitive,  the  reptile  seizes  its  prey  by  throwing  its  coils 
about  a  victim— without  constriction— and  then  swallows  it  alive. 
Constriction  is  a  second  method,  suffocating  the  victim  until  its 
heart  and  lungs  can  no  longer  function  properly.  At  one  time  it 
was  believed  that  constrictors  crushed  the  bones  of  any  creature 
within  their  grip;  today  we  know  this  theory  to  be  erroneous. 

Poison  is  the  third  method  of  killing.  There  are  several  types 
of  poisonous  snakes;  those  known  as  vipers  and  pit  vipers  have 
the  most  effective  poison  apparatus.  The  group  includes  rattle- 
snakes, copperheads,  water  moccasins,  bushmasters,  and  the  trop- 
ical fer-de-lance. 

How  Poison  Fangs  Work 

All  these  snakes  have  hollow  fangs  in  the  upper  jaw, 
firmly  anchored  to  the  bone  above,  which  they  can  move  to 
thrust  the  fangs  forward  for  a  strike.  When  they  are  not  in  use, 
the  fangs  can  be  folded  back  against  the  roof  of  the  mouth. 

As  a  child,  you  may  have  been  told  that  the  mere  pressure  of  a 
snake's  fangs  against  a  solid  substance  brought  forth  the  venom. 


202  ]  Snakes  and  Frogs  and  Their  Relatives 

It  is  not  quite  so  simple  as  that.  The  snake  has  its  poison  supply 
in  two  sacs— one  in  either  cheek.  Each  sac  is  connected  to  the 
fangs  by  a  duct  that  runs  under  the  eye  and  over  the  bone  to 
which  the  fangs  are  attached.  When  the  viper  strikes,  muscles 
that  surround  the  poison  sacs,  contract  and  force  the  venom 
through  the  ducts  into  the  fangs,  from  which  it  flows  to  the 
wound  just  made  in  the  victim's  flesh. 

Hearty  Eaters 

The  ability  of  snakes  to  swallow  objects  larger  than  them- 
selves is  one  of  their  most  spectacular  traits.  The  larger  snakes, 
such  as  pythons  or  boas,  sometimes  devour  a  goat  or  small  deer 
whole.  Such  a  feat  would  be  impossible  without  a  number  of 
special  body  features  with  which  nature  has  provided  them. 

Let's  look  at  their  jaws,  for  example.  An  extra  bone  hinges 
the  upper  jaw  to  the  lower,  allowing  them  to  spread  far  apart. 
Also,  the  lower  jawbones  are  held  together  only  by  elastic  liga- 
ments and  they  can  separate  at  the  chin  to  further  increase  the 
size  of  the  mouth.  The  teeth  point  backward  and  thus  present 
no  obstacle  to  objects  taken  into  the  mouth.  Even  the  snake's  sides 
are  adapted  to  the  task— they  have  great  elasticity  and  can  stretch 
to  many  times  their  normal  dimensions! 

The  Movable  Windpipe 

Despite  all  these  helps,  you  might  still  expect  a  snake  to 
choke  to  death  swallowing  anything  large  enough  to  force  its 
jawbones  wide  apart.  The  snake  overcomes  this  difficulty  by  being 
able  to  extend  a  portion  of  its  windpipe  forward— even  a  few 
inches  beyond  its  open  mouth  if  need  be!  By  this  means  it  can 
breathe  during  the  long  slow  process  of  forcing  down  a  meal 
apparently  far  too  big  for  its  size. 

Some  species  of  snakes  can  live  on  three  or  four  big  meals  a 
year;  others  may  eat  a  moderate  meal  every  week  or  ten  days. 

The  Ways  of  a  Rattler 

Children  are  understandably  curious  about  the  hows  and  whys 
of  a  rattler's  rattle.  How  does  a  tail  tip  turn  into  a  rattle?  Why 
do  some  snakes  have  rattles?  How  does  the  rattle  work? 


Snakes  and  Frogs  and  Their  Relatives 


[203 


The  rattle  is  made  up  of  a  series  of  horny  sections  or  "buttons" 
on  the  end  of  the  spinal  column.  They  are  loosely  interlocked, 
and  when  the  snake  vibrates  its  tail  they  click  against  each  other. 
Many  other  kinds  of  snakes  also  vibrate  their  tails,  and  if  they 
happen  to  be  lying  among  dead  leaves  the  resulting  rustle  sounds 
like  a  rattle.  However,  the  rattlesnake's  vibration  is  distinctive. 
It  is  a  half  metallic,  half  insect-like  sound,  somewhat  like  the 
dull  buzz  of  the  bumblebee. 

The  Rattle  Rings 

At  birth  a  rattler  has  a  bulbous  swelling  at  the  tip  of  its 
tail.  When  the  snake  molts,  the  tip  of  its  old  skin  cannot  be 
pulled  over  this  enlargement,  so  it  remains  and  forms  the  begin- 
ning of  a  rattle.  As  successive  molts  take  place,  the  tip  of  the 
skin  that  cannot  be  shed  forms  an  additional  segment  or  ring. 
The  rings  form  around  a  bone  known  as  the  "shaker,"  made  up 
of  the  last  seven  or  eight  vertebrae  which  fuse  together  soon  after 
the  snake  is  bom.

THE  DANGEROUS  DIAMOND-BACK  RAHIER 

The  diamond-back,  so  called  because  of  the  distinctive  diamond-shaped  pattern  on 
its  back,  is  one  of  the  relatively  few  harmful  snakes  in  the  United  States.  Prac- 
tically all  the  deaths  by  snake  bite  in  this  country  (estimated  at  about  a  hundred  a 
year)  are  caused  by  diamond-back  rattlers,  prairie  and  timber  rattlers,  and  water 
moccasins.  If  proper  treatment  is  given,  their  bites  rarely  prove  fatal. 


204  ]  Snakes  and  Frogs  and  Their  Relatives 

The  old  theory  that  a  ring  is  added  each  year  has  been  dis- 
proved. Sometimes  several  molts  take  place  in  a  year  and  rings 
are  added;  it  is  also  possible  for  the  snake  to  molt  without  a 
new  ring  being  created.  This  irregularity,  not  to  mention  the 
fact  that  rings  are  often  broken  from  the  end,  makes  it  impos- 
sible to  reckon  a  snake's  age  by  the  size  of  its  rattle.  If  a  rattle 
is  unbroken,  however,  you  may  approximate  the  animal's  age 
by  allowing  one  year  for  each  two  rings. 

What  the  Rattle  Is  For 

Many  snakes  have  the  habit  of  vibrating  the  tip  of  the 
tail  when  they  are  excited,  but  the  rattler  is  the  only  kind 
equipped  with  a  "noise-maker."  We  do  not  entirely  understand 
the  purpose  of  the  rattle.  The  once  general  belief  that  this  reptile 
always  rattles  before  striking  is  no  longer  credited.  Apparently 
it  does  use  its  rattle,  as  a  rule,  to  try  to  frighten  enemies  dangerous 
to  its  own  safety. 

As  for  the  theory  of  ''warning"  prospective  prey,  some  ob- 
servers have  decided  that  this  snake  sounds  its  rattle  to  startle 
birds,  rabbits,  or  other  possible  victims  into  momentary  in- 
activity, thus  gaining  time  for  a  strike.  Other  people  claim  that  it 
never  rattles  before  attacking.  There  are  many  reports  of  rattlers 
that  never  rattled  at  any  time,  and  habitually  struck  without 
warning. 

Kinds  of  Rattlesnakes 

There  are  no  less  than  fifteen  different  species  of  rattle- 
snakes in  the  United  States  and  they  live  in  many  localities.  The 
deadly  diamond-back  of  the  southeastern  states  frequents  neigh- 
borhoods where  water  is  plentiful,  the  timber  rattler  lives  in 
woodland  mountain  regions,  the  prairie  rattler  haunts  the  Great 
Plains  of  the  West;  another  species  is  found  in  desert  wastes. 

Rattlers  are  among  the  more  important  kinds  of  snakes  in 
our  country  that  bear  live  young.  The  mother  gives  her  oflE- 
spring  no  care— but  none  is  necessary.  They  are  able  to  fend  for 
themselves  immediately,  and  have  been  seen  eating  ten  minutes 
after  birth!

Spectacular  Deadly  Snakes 

A  visit  to  the  snake  house  at  a  zoo  gives  you  a  first-hand 
acquaintance  with  species  you  would  never  welcome  as  house 
pets,  though  they  are  well  thought  o£  by  zoo  keepers. 

The  Good-natured  Boa 

One  of  these  deadly  creatures  is  the  boa  constrictor— a 
big  reptile  of  South  America  that  reaches  a  length  of  eighteen 
feet.  It  is  quite  hardy  in  captivity,  and  many  specimens  are  good- 
natured  and  easily  fed  with  birds  and  small  mammals.  Though 
most  South  American  Indians  dread  this  boa  and  believe  it  to  be 
poisonous,  it  is  not.  As  a  rule  this  boa  seems  anxious  to  keep 
away  from  humans,  but  it  will  occasionally  appear  in  a  native 
village,  apparently  attracted  by  the  domestic  fowl. 

Still  greater  in  size  than  the  boa  constrictor  is  a  water  boa 
known  as  the  anaconda,  native  to  the  river  valleys  of  nothern 


THE  ANACONDA  -  GIANT  AMONG  SNAKES 

A  huge  boa  fossil  of  about  fifty  million  years  ago,  unearthed  in  Egypt,  Is  supposed 
to  hove  been  fifty  feet  long.  Our  modern  anaconda  (or  water  boa),  the  largest 
of  New  World  snakes,  has  a  length  of  over  twenty  feet.  It  lives  in  South  America 
and  though  it  spends  much  of  its  time  in  the  water,  it  is  also  on  expert  tree  climber. 
The  anaconda  is  not  poisonous.  It  will  seldom  attack  humans  without  provocation. 


2o6  ]  Snakes  and  Frogs  and  Their  Relatives 

South  America.  Reliable  records  show  that  this  species  sometimes 
attains  a  length  of  twenty-eight  feet.  The  anaconda  is  the  largest 
snake  in  the  New  World. 

Pythons— The  Largest  Snakes 

Among  the  most  fearsome-looking  reptiles  are  the  pythons, 
which  have  been  imported  from  Asia  or  Africa.  There  are  giants 
among  them:  a  twenty-five-foot  Indian  python  may  weigh  more 
than  two  hundred  pounds;  the  reticulated  python,  not  quite  so 
thick  in  body,  may  be  nearly  thirty  feet  long.  The  large  pythons 
eat  a  variety  of  animals,  but  their  taste  runs  to  fairly  large 
mammals. 

"Snake-charming"  showmen  frequently  use  relatively  small  speci- 
mens of  the  rock  python  in  their  acts,  as  these  snakes  become 
very  docile  in  captivity.  Nevertheless,  there  is  always  some  danger. 
If  the  snake  accidentally  throws  a  complete  coil  about  the  body 
of  the  performer,  it  will  begin  to  constrict  and  throw  new  coils. 
The  "charmer"  must  quickly  straighten  out  the  reptile  or  be  in 
real  danger  of  strangulation.  Anyone  who  closely  watches  a  snake 
charmer  with  a  python  or  boa,  will  observe  that  every  movement 
of  his  hands  and  arms  is  made  solely  to  prevent  the  snake  from 
forming  a  coil. 

The  Cobra's  Double  Personality 

A  child  who  has  been  reading  colorful  stories  of  the  Orient 
in  which  cobras  play  a  sinister  part,  may  well  be  disappointed 
when  he  sees  this  snake  in  the  zoo.  When  it  is  not  excited,  this 
dangerously  venomous  reptile  looks  quite  commonplace.  Alarmed 
or  angry  the  cobra  presents  a  far  different  picture,  weaving  its 
raised  head  back  and  forth  with  its  hood  erect. 

The  Cobra's  Terrifying  Hood:  The  hood  is  actually  only  the 
skin  of  the  neck  stretched  taut.  The  cobra  has  a  series  of  ribs  on 
the  sides  of  the  vertebrae  of  the  neck,  and  when  it  is  excited  it 
uses  powerful  muscles  to  draw  these  ribs  forward,  thus  stretching 
its  skin  and  forcing  the  scales  wide  apart. 

Seen  from  in  back  when  its  hood  is  spread,  the  Indian  cobra 
gives  the  impression  of  having  eyes  on  top  of  its  head.  But  what 


Snakes  and  Frogs  and  Their  Relatives  [  207 

the  observer  sees  are  merely  markings;  the  eyes  are  at  the  sides 
of  the  head,  little  of  which  is  visible  when  the  hood  is  open.  It 
is  a  mistake  to  think  that  cobras  can  be  identified  by  the  erection 
of  the  hood;  other  snakes—such  as  the  harmless  hognose  snake- 
possess  the  same  ability. 

While  people  most  frequently  think  of  India  as  the  home  of 
cobras,  these  snakes  also  dwell  in  Africa.  The  king  cobra,  which 
may  grow  as  long  as  eighteen  feet,  is  the  largest  venomous  snake 
known.  It  is  very  aggressive  and  its  poison  is  deadly.  The  common 
Indian  cobra,  which  rarely  attains  a  length  of  more  than  six  feet, 
also  causes  many  deaths  every  year. 

Some  Common  Harmless  Snakes 

The  Garter  Snake 

We  have  many  kinds  of  garter  snakes  in  the  United  States 
and  they  are  well  distributed  all  over  the  country.  The  "common" 
variety  (often  called  the  garden  snake)  is  found  in  the  eastern 
states  up  into  Canada.  You  cannot  be  sure  of  recognizing  it  by 
its  color,  which  varies  in  different  individuals. 

The  ground  or  major  body  color  may  be  olive,  brown,  or 
black.  There  is  usually  a  stripe  of  yellow,  green,  or  whitish  hue 
down  the  center  of  the  back.  Along  each  side  is  a  similar  stripe, 
subdued  in  tone,  which  may  be  broken  up  into  spots.  The  under- 
side is  greenish  white  or  yellow.  A  full-grown  specimen  is  about 
thirty  inches  long. 

Where  Garter  Snakes  Are  Found:  You  are  most  likely  to  come 
upon  garter  snakes  in  summer  along  the  banks  and  edges  of 
streams  where  their  favorite  foods— toads,  frogs,  earthworms,  and 
insects— are  plentiful.  In  the  fall  they  are  likely  to  gather  on 
rocky  ledges  or  stony  hillsides.  Here  each  finds  a  crevice  or  makes 
a  burrow,  which  may  extend  more  than  a  yard  underground, 
where  it  sleeps  through  the  cold  weather. 

Hognose  Snakes— Ham  Actors 

The  garter  snake  and  the  hognose  snake  both  make  excel- 
lent pets— though  the  hognose  variety  has  bluffed  its  way  into  a 


2o8  ]  Snakes  and  Frogs  and  Their  Relatives 

bad  reputation.  When  it  is  frightened,  it  immediately  swells  its 
body,  flattens  its  neck  like  a  cobra,  and  hisses  in  a  vicious  manner. 
These  fearsome  actions  have  earned  it  such  names  as  "spreading 
adder,"  "blowing  viper,"  and  "blow  snake." 

However,  the  hognose  has  no  poisonous  power  whatever.  If 
it  succeeds  in  bluffing  its  enemy,  it  quickly  calms  down  and  crawls 
into  seclusion.  If  the  bluff  fails,  "hognose"  plays  dead,  rolling 
over  on  its  back  and  becoming  completely  quiet! 

How  the  Hognose  Got  Its  Name:  This  snake  has  a  remarkable 
nose.  It  is  equipped  with  a  hard,  trowel-shaped  shield  that  plows 
efficiently  into  loose  soil  and  often  roots  out  toads  that  are  buried 
near  the  surface.  Its  diet  is  made  up  exclusively  of  toads  and  frogs. 

The  Maligned  Milk  Snake 

This  snake  is  the  subject  of  one  of  the  most  fantastic  of 
all  snake  myths.  According  to  the  fable,  the  milk  snake  milks 
cows.  Not  only  is  this  feat  physically  impossible,  but  no  milk 
snake  in  captivity  could  ever  be  persuaded  to  drink  milk.  This 
snake's  presence  in  barns  and  stables  is  explained  by  its  liking 
for  mice  and  rats  as  food.  Thus,  instead  of  being  a  menace,  the 
milk  snake  is  an  ally  of  the  farmer. 

Though  the  milk  snake's  ground  color  is  light  gray,  it  is  cov- 
ered with  so  many  brown  or  dark  gray  spots  that  either  of  these 
may  seem  to  be  the  predominating  color.  The  underside  is  white 
with  square  black  spots  and  blotches.  A  fully  grown  specimen 
ranges  from  thirty  inches  to  three  feet  long. 

King  Snakes— Cannibals 

The  common  king  snake  is  an  impressive-looking  creature, 
for  it  may  attain  a  length  of  six  feet.  In  the  natural  state  it  is  a 
cannibal;  in  fact  it  is  noted  for  its  attacks  on  other  snakes— even 
rattlers.  It  is  black  and  decorated  with  yellow  spots  and  bands. 
Strangely  enough,  some  king  snakes  in  captivity  show  no  interest 
in  snakes  as  food,  while  others  will  eat  nothing  else.  King  snakes 
are  nevertheless  easy  to  feed  as  a  rule,  and  are  inclined  to  be 
docile  with  their  keepers.  There  are  fourteen  different  kinds  of 


Snakes  and  Frogs  and  Their  Relatives  [  209 

king  snakes,  and  they  are  found  throughout  most  of  the  United 
States. 

Water  Snakes— Harmless  and  Dangerous  Kinds 

Children  who  go  fishing  are  very  likely  to  encounter  this 
dingy  brown  reptile,  which  haunts  dams,  wharves,  rocks  and 
bushes  near  water.  Because  of  its  protective  color  plan  it  may 
escape  notice  until  it  moves  suddenly.  Like  the  hognose  snake, 
it  puts  on  a  great  show  when  cornered,  flattening  out  its  body 
and  striking  fiercely. 

However,  the  water  snake  has  no  venom  and  its  teeth  can 
inflict  only  harmless  wounds.  It  makes  a  good  pet.  While  it  will 
eat  almost  anything,  it  particularly  likes  fish.  Its  usual  size  is 
from  thirty  inches  to  three  feet.  Water  snakes  are  found  over 
almost  all  of  eastern  North  America. 

From  southern  Virginia  to  Florida  and  the  Gulf  states,  you 
must  be  extremely  cautious  about  water  snakes;  for  this  section 
is  the  home  of  the  deadly  water  moccasin,  which  has  a  superficial 
resemblance  to  the  harmless  water  snake. 

How  to  Recognize  a  Poisonous  Snake 

A  child  who  is  determined  to  be  not  only  an  observer  of  snakes 
but  also  a  collector  of  them,  should  be  well  coached  in  safety 
rules.  Of  first  importance  is  knowing  the  character  of  all  snakes 
in  your  locality.  If  there  are  poisonous  species  among  them,  it 
is  essential  to  distinguish  them  from  the  harmless  ones.  Collecting 
poisonous  species  should  be  left  to  the  experts! 

The  poisonous  snakes  of  the  United  States  fall  into  four  groups: 
rattlesnakes,  which  have  been  found  in  every  state;  copperheads, 
which  are  distributed  from  New  England  to  Texas  and  in  all  the 
southern  states;  water  moccasins,  found  chiefly  in  the  southern 
and  southeastern  states;  and  coral  snakes,  which  live  only  in  the 
deep  South,  from  North  Carolina  to  Texas  and  parts  of  Arizona. 
While  this  broad  distribution  sounds  forbidding,  there  are  many 
areas  within  these  regions  where  you  will  find  only  harmless 
species. 


2  lo  ]  Snakes  and  Frogs  and  Their  Relatives 

What  Poisonous  Snakes  Look  Like 
The  rattlesnakes  vary  considerably  in  size  and  general 
appearance,  but  all  of  them  are  identified  by  their  "rattles."  You 
can  distinguish  copperheads  by  hourglass-shaped  markings  on  the 
back.  Usually,  but  not  always,  the  top  of  the  head  is  bronze  or 
copper  colored. 

Water  moccasins  have  markings  resembling  those  of  the  copper- 
head, but  they  are  not  noticeably  copper  colored.  The  inside  of 
the  mouth  has  a  whitish  color.  Unlike  most  snakes,  which  try  a 
hurried  retreat  at  the  approach  of  an  enemy,  water  moccasins 
stand  their  ground  and  fight  any  intruder  in  their  territory. 

Coral  snakes  are  brightly  colored,  with  red,  yellow,  and  black 
rings  encircling  the  body.  They  closely  resemble  certain  harmless 
species,  and  considerable  concentration  is  needed  to  distinguish 
the  harmless  types  from  the  deadly  poisonous  coral  species. 

When  You  Encounter  a  Snake 

If  you  accidentally  come  upon  a  snake  and  are  frightened, 
just  bear  in  mind  that  the  snake  is  doubtless  as  anxious  to  get 
away  from  you  as  you  are  to  avoid  it.  Remember  that  it  has  no 
"power  of  hypnotism."  This  has  been  proved  many  times  by 
experiments  in  which  birds,  guinea  pigs,  and  other  animals  were 
placed  in  cages  with  a  snake  and  where  they  acted  entirely  un- 
concerned about  their  reptile  companion.  If  you  can  think  of  a 
snake  as  "just  another  animal,"  it  will  be  easy  for  you  to  remain 
calm  and  move  away  from  your  unwelcome  discovery. 

If  you  are  actively  interested  in  snake  collecting,  you  ought  to 
be  thoroughly  familiar  with  first-aid  treatment  for  poisonous 
snake  bite  and  have  a  snake-bite  kit  along  on  all  field  trips  if 
there  are  poisonous  species  in  the  vicinity. 

You  will  also  want  to  have  a  "snake  stick"  for  capturing  live 
specimens.  A  two-pronged  metal  fork  attached  to  a  pole,  or  a  cut 
stick  with  a  forked  end,  may  serve  your  purpose.  You  can  pin  down 
the  snake  behind  the  head  until  you  are  ready  to  pick  it  up  and 
transfer  it  to  a  bag.

Snakes  As  Pets 

When  a  youngster  has  captured  a  harmless  snake  and  is  keeping 
it  as  a  pet,  he  may  wish  to  build  a  cage  especially  for  his  prize. 
However,  an  ordinary  rectangular  fish  tank  will  serve  the  purpose 
effectively  for  a  small  specimen  such  as  a  ribbon  or  garter  snake. 
To  accommodate  a  king  snake  or  one  of  the  other  big  fellows,  the 
cage  should  be  at  least  equal  in  length  to  the  reptile's  body.  This 
will  make  it  possible  for  the  snake  to  coil  and  uncoil  and  move 
about  comfortably. 

A  cage  should  have  a  water  dish  large  enough  for  the  snake  to 
crawl  into.  A  big  ash  tray  is  convenient  and  large  enough  for  a 
garter  snake.  Cover  the  floor  of  the  cage  with  moss,  gravel,  or 
slightly  moistened  sand  to  make  cleaning  easier.  The  cage  should 
be  wiped  out  regularly  with  warm  water  and  soap,  and  the  floor 
covering  changed.  All  waste  matter  and  uneaten  food  must  be 
removed  daily. 

There  is  no  harm  in  exposing  a  snake  to  direct  sunlight  pro- 
vided that  shade  is  available  at  all  times.  Sun  that  does  not  feel 
excessively  hot  to  your  hand  may  be  dangerously  hot  for  a  snake; 
a  reptile's  body  absorbs  heat  and  becomes  warmer  and  warmer, 
as  would  a  piece  of  iron  lying  in  the  sun.  A  rock  or  block  of  wood 
placed  in  the  cage  helps  furnish  shade,  and  it  is  also  useful  to 
the  snake  for  rubbing  against  when  it  sheds  its  skin. 

Proper  Diet  for  a  Pet  Snake:  A  captive  snake  that  has  eaten  well 
from  spring  through  fall  may  safely  go  through  several  winter 
months  without  eating.  But  if  you  have  a  local  specimen  that 
refuses  food  for  nine  or  ten  weeks  during  warm  weather,  it  is 
best  to  give  it  its  freedom.  Forcible  feeding  by  an  inexperienced 
person  is  sure  to  be  fatal  to  the  snake. 

Of  course  it  is  necessary  to  know  which  snakes  will  eat  what. 
Thus,  garter  snakes  thrive  on  frogs,  tadpoles,  and  earthworms; 
larger  species,  including  black  racers  and  pilots,  eat  rats,  mice, 
rabbits,  and  gophers.  King  snakes  may  eat  other  snakes,  as  they 
do  in  the  natural  state,  or  they  may  prefer  rodents.  Very  small 
species  such  as  the  green  snake  eat  earthworms,  grasshoppers,  and 
other  insects.  The  insect-eating  snakes  need  more  frequent  feed- 
ings than  those  that  feed  on  rodents. 


212]  Snakes  and  Frogs  and  Their  Relatives 

You  may  be  told  that  snakes  will  not  touch  dead  animals,  but 
zoo  keepers  have  found  that  these  reptiles  will  consume  dead 
prey  as  readily  as  living  victims.  The  keepers  sometimes  teach 
them  to  eat  raw  meat  by  first  serving  it  mixed  with  chopped  earth- 
worms, then  gradually  reducing  the  quantity  of  worms.  When 
dead  food  is  used,  it  is  moved  right  in  front  of  the  snake  to  attract 
its  attention. 

Captive  snakes  are  likely  to  be  frightened  by  sudden  move- 
ments of  your  hand.  "Slow  and  easy"  is  the  best  rule  in  dealing 
with  them.  When  you  lift  a  snake,  give  its  long,  slender  body 
adequate  support;  the  animal  is  not  comfortable  when  it  is 
dangled  by  the  head  or  the  tail. 

If  snakes  capture  your  family's  imagination,  a  generally  satis- 
factory program  is  to  try  keeping  one  or  two  during  the  summer 
and  then  to  release  them  so  that  they  may  hibernate  under  natural 
conditions  in  wintertime. 

Turtles 

Of  all  reptile  pets,  turtles  are  probably  the  most  commonly 
enjoyed.  Your  child  is  apt  to  bring  home  one  of  these  creatures 
from  camp  or  from  an  outing  to  ponds  or  fields;  or  they  may  be 
bought  in  pet  or  novelty  stores. 

Unfortunately  thousands  of  turtles  are  entrusted  to  the  care 
of  people  who  understand  little  about  their  way  of  life.  If  your 
child  has  a  turtle,  you  and  he  will  certainly  want  to  know  more 
about  it.  And  even  if  you  don't  have  a  turtle  pet,  you  will  agree 
that  it  is  a  fascinating  animal  to  watch  and  study  if  you  are  at  all 
interested  in  nature's  ways. 

Armor  Plate  for  Defense 

At  first  glance  a  turtle  may  give  the  impression  of  an  inani- 
mate piece  of  armor;  when  it  is  uncertain  of  its  surroundings,  it  cau- 
tiously keeps  every  bit  of  its  body  under  its  hard  shell.  Once  the 
turtle  feels  safe,  however,  you  will  see  the  snakelike  head  project 
from  the  front  of  its  shell,  the  pointed  tail  poke  out  from  the 
rear,  and  two  wide  legs  appear  at  each  side.  Then  you  will  notice

THE  PAINTET*  TURTLE  AND   ITS  ATTRACTIVE  SHELL 

Encased  In  armor,  turtles  have  sturdily  maintained  themselves  against  their  enemies 
for  many  millions  of  years.  They  ore  wary  and  unsociable  creatures— at  least  when 
they  suspect  the  presence  of  an  enemy.  The  painted  turtle,  with  a  shell  about  six 
inches  long,  has  vivid  markings  of  red  and  yellow  on  its  blackish  or  olive  upper 
shell.  It  feeds  on  water  plants  and  animals,  eats  them  only  under  water. 

that  even  the  soft  body  is  covered  with  rough,  coarse  skin  and 
often  with  many  scales. 

You  can  appreciate  the  effectiveness  of  this  protective  covering 
when  you  realize  that  turtles  have  survived  for  many  millions  of 
years  with  no  means  of  fighting  countless  larger  animals  that 
might  attack  them.  Their  success  is  strictly  due  to  defense  equip- 
ment. (A  noteworthy  exception,  of  course,  is  the  big  snapper 
with  its  vicious  hooked  beak.) 

The  Protective  Shell:  The  upper  shell  (the  "carapace")  varies 
in  shape  depending  on  the  species  of  turtle.  This  shell  grows 
attached  to  the  turtle's  backbone;  in  a  few  species  the  carapace 
is  quite  flat,  in  others  it  is  rounded. 

The  lower  shell  (the  "plastron")  also  varies  in  shape  and  size 
and  is  attached  to  the  breastbone.  There  is  also  a  great  deal  of 
variation  from  one  species  to  one  another  as  to  size  and  color  of 
the  turtle's  body.  Other  oddities  include  the  tail  of  the  snapping 


214]  Snakes  and  Frogs  and  Their  Relatives 

turtle,  which  bears  a  saw-toothed  armor  of  plates,  and  the  front 
and  rear  "trap  doors"  which  the  box  turtle  can  pull  up  against 
the  carapace  to  enclose  the  body  completely! 

A  child  may  wonder  how  a  creature  encased  so  completely  can 
manage  to  breathe.  The  turtle's  shoulder  and  hip  bones  do  most 
of  the  work  in  contracting  and  expanding  the  lungs.  The  con- 
stant pulsation  you  can  observe  in  the  throat  is  caused  by  air 
being  swallowed. 

Sight,  Smell,  and  Teeth 

Like  snakes,  turtles  lack  movable  eyelids.  However,  turtles 
have  a  protective  membrane  which  comes  up  from  the  lower  edge 
to  cover  the  eye.  Some  species  have  nostrils  no  larger  than  pin- 
holes, and  their  poor  sense  of  smell  is  not  surprising.  Others, 
better  equipped,  have  a  keen  sense  of  smell. 

Though  a  turtle  has  no  real  teeth,  its  mouth  has  sawlike  cutting 
edges.  It  does  not  bother  to  chew  food  but  simply  tears  it  to  pieces. 

How  TO  Take  Care  of  Turtle  Pets 

We  naturally  avoid  the  big  snapping  turtles,  but  the  small 
ones  are  good  pet  material  because  they  are  hardy  and  usually 
easy  to  feed.  (This  is  also  true  of  musk  turtles.)  The  kind  you 
are  most  likely  to  find  in  pet  shops  is  the  Troost's  turtle,  which 
is  green  with  yellow  markings. 

Keeping  a  Turtle  Pet  Comfortable:  To  keep  water  turtles  healthy, 
you  must  give  them  some  means  of  getting  out  of  water  to  dry 
and  sun  themselves.  If  they  are  lodged  in  a  tank  or  aquarium,  a 
stone  island  or  floating  piece  of  wood  will  answer  the  purpose. 

Instead  of  an  aquarium,  you  may  use  a  dry  cage  or  box  to 
advantage.  In  that  case  you  must  furnish  it  with  a  dish  of  water 
deep  enough  to  serve  as  a  swimming  pool,  and  so  arranged  that 
the  turtle  will  find  it  easily  accessible.  The  rest  of  the  floor  of 
the  cage  may  be  covered  with  stones,  sand,  gravel,  or  moss. 

The  water,  especially  in  the  aquarium-type  housing,  should 
consistently  be  between  75  and  85  degrees.  Chilling  at  night  must 
be  avoided.  (Most  pet  turtles  come  from  southern  states,  and  they 
need  a  little  extra  warmth  in  order  to  thrive  in  northern  regions.) 


Snakes  and  Frogs  and  Their  Relatives  [215 

While  turtles  should  have  an  abundance  of  sunshine  (or  even 
bask  under  a  sun  lamp) ,  they  must  also  have  a  shady  retreat. 
Too  much  heat  can  kill  them. 

Menus  for  Turtle  Pets:  Most  water  turtles  prefer  to  swallow  their 
food  under  water.  Small  bits  put  on  a  broom  straw  will  often 
arouse  an  indifferent  pet.  Raw,  lean  meat  or  fish  scraped  or 
chopped  fine  is  usually  acceptable;  but  small  worms,  insects, 
tadpoles  and  other  little  creatures  are  the  natural  food  of  young 
turtles  and  are  excellent  if  available. 

A  good  way  to  supplement  the  home  diet  is  to  mix  a  bit  of 
bone  meal  and  a  drop  of  cod-liver  oil  frequently  with  meat.  Let- 
tuce and  other  greens  or  raw  fruits  and  vegetables  add  variety  to 
the  menu.  Baby  turtles  may  be  fed  as  often  and  as  much  as  they 
will  eat;  but  a  good  feeding  about  twice  a  week  should  be  enough. 
A  straight  diet  of  "ant  eggs"  or  house  flies  is  not  satisfactory. 

Turtle  Ailments  and  Remedies:  Turtles  are  often  afflicted  with 
softening  of  the  shell  and  swollen,  closed  eyes.  Recommended 
remedies  are  a  warmer  cage,  more  sunlight,  and  a  more  balanced 
diet.  Swollen  eyes  should  be  carefully  wiped  twice  a  day  with 
cotton  dipped  in  warm  boric-acid  solution.  When  a  turtle  refuses 
food  for  a  long  time,  its  appetite  may  improve  if  you  give  the 
animal  more  warmth  and  sunlight.  In  winter  there  is  a  natural 
tendency  for  turtles  to  eat  less  frequently  and  to  be  less  active. 

Some  Common  Turtles 

Ponds  are  the  most  likely  places  to  encounter  turtles, 
though  aside  from  the  species  that  frequent  ponds  there  are  also 
sea  turtles  and  those  that  live  exclusively  on  land.  "Tortoise"  is  a 
general  term  that  covers  all  types.  "Turtle"  is  usually  applied  to 
sea  or  fresh-water  forms;  "terrapin"  is  the  name  (of  Indian  origin) 
for  certain  American  fresh-water  species. 

You  may  find  a  wood  tortoise  in  the  damp  woods,  far  away 
from  water.  Its  upper  shell— one  of  its  distinguishing  features- 
may  reach  a  length  of  six  and  a  half  inches.  It  is  made  up  of  many 
plates  ornamented  with  concentric  ridges.  With  the  exception  of 
the  top  of  the  head  and  the  limbs,  all  the  fleshy  parts  of  this 
creature  are  brick-red.  It  thrives  in  captivity  and  will  soon  learn

THE  GIANT  TORTOISES  OF  THE  GALAPAGOS  ISLANDS 

In  contrast  to  the  six-inch  painted  turtle,  the  giant  tortoise  reaches  a  length  of 
four  feet  and  weighs  as  much  as  five  hundred  pounds.  It  was  once  a  favorite  source 
of  meat  for  Pacific  whalers  that  touched  at  the  islands  ofF  Ecuador.  Though  these 
giant  tortoises  may  live  to  well  over  a  hundred  years  in  the  natural  state,  they 
have  been  subjected  to  relentless  extermination  by  man. 

to  accept  food  from  your  fingers.  Tender  vegetables,  berries, 
insects,  and  chopped  meat  form  an  acceptable  diet. 

Another  turtle  that  you  can  tame  with  very  satisfactory  results 
is  the  spotted  turtle,  found  in  many  ponds  and  marshy  streams. 
Its  black  upper  shell  is  decorated  with  numerous  spots,  whence 
its  name.  The  spotted  turtle  enjoys  perching  on  a  log  for  long 
stretches  of  time,  but  its  feeding  is  done  under  water. 

You  may  recognize  another  pond  turtle— often  called  the  painted 
terrapin— by  the  red  mottled  border  of  its  shell.  This  is  a  good 
aquarium  pet  but  it  is  much  too  aggressive  to  be  kept  with  other 
creatures. 

Snapping  turtles,  so  intriguing  as  babies,  may  attain  a  weight 
of  forty  pounds  as  adults,  with  a  shell  fourteen  inches  long.  Be 
on  the  watch  for  them  in  slow-running  streams,  ponds,  or  marshes. 

The  "alligator  snapper"  of  the  South  sometimes  weighs  a 
hundred  pounds. 


Snakes  and  Frogs  and  Their  Relatives  [217 

The  mud  turtle  and  the  musk  turtle  are  really  water  dwellers 
to  all  intents  and  purposes;  the  only  time  they  come  to  shore  is 
to  deposit  their  eggs.  They  find  their  food  in  muddy  bottoms  of 
ponds  and  streams,  and  eat  only  under  water.  The  musk  turtle, 
which  has  two  broad  yellow  stripes  on  either  side  of  its  head,  gives 
off  a  strong  odor  on  being  handled.  The  head  of  the  mud  turtle 
is  ornamented  with  greenish  yellow  spots. 

The  box  turtle,  unlike  the  mud  and  musk  turtles,  lives  entirely- 
on  land.  It  is  easy  to  recognize  this  species  by  the  hinges  on  the 
front  and  rear  of  the  lower  shell  by  which  it  can  **box"  itself 
completely  within  its  armor.  This  turtle  grows  to  a  length  of 
about  five  inches. 

After  the  wintertime  hibernation  a  turtle  deposits  her  eggs  in  a 
shallow  hole  in  earth  or  sand.  As  a  rule  there  are  five  or  six  eggs, 
though  some  species  lay  more— the  snapper,  for  example,  usually 
produces  about  two  dozen. 

Chameleons  and  Other  Lizards 

If  you  take  a  casual  look  at  a  lizard,  it  will  remind  you  very 
much  of  a  snake.  Outwardly  there  is  not  much  difference  between 
them— except  that  most  lizards  have  legs.  Nevertheless,  a  legless 
lizard  is  a  lizard,  not  a  snake. 

One  definite  difference  you  can  observe  between  the  two  groups 
is  in  the  structure  of  the  lower  jawbone.  In  all  snakes  the  lower 
jaw  is  made  up  of  two  bones  joined  at  the  chin  by  a  more  or  less 
flexible  ligament.  The  lizard  also  has  a  lower  jawbone  on  either 
side,  but  these  are  attached  firmly  at  the  center  of  the  chin. 

Another  visible  difference  is  that  lizards  generally  have  movable 
eyelids— something  no  snake  possesses. 

The  Secret  of  the  Chameleon's  Color  Changes 

At  a  fair  or  circus,  boys  and  girls  frequently  buy  a  souvenir 
in  the  form  of  a  little  lizard  which  they  are  told  is  a  chameleon.  As 
it  happens,  true  chameleons  are  seldom  seen  in  our  country; 
they  are  animals  of  the  Old  World,  belonging  especially  to  Africa. 
But  another  kind  of  lizard,  often  called  the  "American  chamele- 
on," also  has  the  ability  of  the  true  chameleons  to  change  color 


2 1 8  ]  Snakes  and  Frogs  and  Their  Relatives 

frequently.  It  is  this  American  lizard  that  is  usually  peddled  at 
amusement  places. 

Most  children  are  apt  to  overrate  the  chameleon's  ability  to 
change  color;  they  take  the  excessively  simplified  view  that  the 
animal  speedily  alters  to  the  color  of  whatever  object  it  stands 
upon.  Chameleons  do,  to  a  great  extent,  harmonize  with  the 
foliage  on  which  they  rest;  but  several  other  factors  are  involved. 

Light  and  temperature  are  important  influences  in  changing  the 
animal's  color— and  so  are  excitement  and  fright.  Not  only  does 
the  tone  of  the  body  change,  but  strange  patterns  come  and  go  on 
the  skin.  How  does  this  happen?  To  put  it  briefly:  Beneath  the 
reptile's  skin  are  a  number  of  tiny  branched  cells  containing 
pigments  of  various  colors.  Whenever  the  chameleon  contracts 
or  expands  these  branches,  the  position  of  the  pigments  is  changed. 
Those  that  travel  to  the  surface  of  the  skin  are  partly  responsible 
for  the  color  the  animal  suggests. 

All-around  Eyes  and  a  Quick  Tongue 

The  true  chameleon  has  a  versatility  that  can  be  positively 
startling.  It  can  roll  one  eye  upward  while  the  other  rolls  down— 
or  turn  one  eye  forward  and  the  other  backward!  Its  tongue  is  a 
"secret  weapon"  that  shoots  forward  to  a  distance  of  seven  or 
eight  inches.  On  its  sticky  tip  the  chameleon  snares  insects  that 
apparently  were  well  out  of  harm's  way. 

How  TO  Keep  a  Chameleon  Pet 

Old  World  chameleons  rarely  eat  in  captivity  and  seldom 
live  longer  than  five  or  six  months  when  they  are  kept  confined. 
The  so-called  "American  chameleon"  is  not  so  remarkable  an 
animal,  but  it  does  make  a  better  pet. 

The  American  species  should  be  kept  in  a  warm  sunny  place 
and  fed  crickets,  cockroaches,  or  live  flies.  If  it  loses  interest  in 
eating,  you  may  revive  its  appetite  by  moving  food  slowly  in 
front  of  it.  Your  chameleon  needs  water;  but  do  not  put  it  in  a 
pan  or  cup  in  the  cage.  Instead,  sprinkle  the  water  about  the  cage 
so  that  the  little  creature  can  lap  up  the  drops  just  as  it  drinks 
dew  from  leaves  in  its  natural  state.

Lizards  of  the  Southwest 

Children  who  live  in  the  southwestern  United  States,  and 
others  whose  vacation  travels  take  them  over  some  of  the  arid 
stretches  of  this  region,  may  encounter  a  variety  of  lizards.  There 
is  the  whiptail  or  race  runner,  a  striped  species  that  is  active  all 
day  in  open  areas;  the  collared  lizard,  a  scrappy  fighter  that  has 
been  known  to  attack  rattlesnakes;  the  big  chuckwalla,  which 
may  grow  as  long  as  sixteen  inches;  and  the  banded  gecko,  a 
lizard  active  chiefly  at  night. 


THE  RESOURCEFUL  FENCE  LIZARD 

This  lizard,  about  six  inches  long,  has  a  very  lengthy  tail.  If  a  pursuer  grasps  the 
tail  the  lizard  is  able  to  shed  it,  later  growing  a  new  one  to  replace  the  one  it 
lost.  In  some  lizards  the  tail  is  four  or  five  times  the  length  of  the  rest  of  the  bodyi 

The  only  poisonous  lizard  found  in  the  United  States  is  the 
Gila  monster— a  colorful  figure  strongly  marbled  with  coal  black 
and  some  other  marking,  often  pink,  yellow,  or  white.  Its  stout 
body  may  grow  to  a  length  of  twenty  inches,  although  eighteen 
inches  is  pretty  much  the  average.  Its  bite  can  quickly  kill  a 
small  mammal  and  seriously  affect  a  human  being. 

Lizards  are  able  to  grow  a  new  tail  when  they  have  lost  the

THE  ONLY  POISONOUS  LIZARD  OF  THE  UNITED  STATES 

The  attractively  colored  Gila  monster  is  large  for  a  lizard— about  twenty  inches 
long  or  so.  It  lives  in  our  southwestern  desert  lands,  and  has  the  useful  trait  of 
being  able  to  store  food  in  its  tail!  The  Gila  monster  moves  sluggishly  as  a  rule, 
but  strikes  quickly  when  injecting  its  venom.  It  rarely  bites,  and  its  poison  is  not 
fatal  to  humans.  It  lays  its  eggs  in  the  sand,  where  the  sun  hatches  them. 

original  one  through  some  mishap.  The  true  chameleon,  however, 
lacks  this  regrowing  ability. 

Alligators  and  Crocodiles 

A  child  is  likely  to  see  these  giant  reptiles  only  in  zoos,  for 
their  natural  range  in  the  United  States  is  limited  to  the  swamps 
and  lagoons  of  the  Carolinas,  Georgia,  and  Florida  west  to  Texas. 
If  he  (or  his  parent)  looks  at  these  animals  only  casually,  he  is 
sure  to  ask  this  natural  question: 

"What's  the  difference  between  an  alligator  and  a  crocodile?" 

How  Alligators  and  Crocodiles  Differ:  If  you  look  closely,  you 
will  quickly  perceive  a  decided  difference  in  the  shape  of  the 
snout.  You  will  see  that  the  alligator's  snout  is  wide  and  more 
rounded  than  that  of  the  crocodile. 

There  is  also  a  difference  in  the  teeth.  In  the  case  of  the  croco- 
dile, the  fourth  tooth  on  either  side  of  its  lower  jaw  fits  into 
notches  on  the  outside  of  the  upper  jaw— so  that  even  when  its 


Snakes  and  Frogs  and  Their  Relatives 


[  221 


mouth  is  closed,  the  vicious  fangs  show.  The  usual  effect  is  to 
give  the  crocodile  a  fiercer  and  more  belligerent  appearance  than 
the  alligator.  Nor  are  looks  deceiving  here,  for  on  the  whole 
alligators  are  timid  and  try  to  escape  any  encounter  with  human 
beings,  whereas  crocodiles  are  sulky  and  ferocious  by  turns. 

In  the  zoo  a  keeper  will  often  step  among  and  over  alligators 
while  cleaning  their  swimming  pool— but  he  does  not  take  such 
chances  with  his  crocodile  charges.  At  the  circus  you  may  see-the 
"strong  man"  wrestle  with  the  lazy  and  slow-moving  alligator— 
never  with  the  quick  and  active  crocodile. 

Both  alligators  and  crocodiles  spend  much  of  their  time  in 
water.  Their  nostrils,  located  on  top  of  little  bumps  at  the  end 
of  the  snout,  take  in  air  as  the  animals  float  just  under  the  surface 
of  the  water.  They  can  even  feed  under  water  by  shutting  off 
the  food  tube  from  the  tube  that  leads  to  the  lungs. 

Unlike  most  reptiles,  alligators  and  crocodiles  are  able  to  make 
noises  with  their  mouths.  The  young  produce  a  curious  grunting 
sound,  while  the  bellowing  of  the  old  bulls  may  be  heard  a  mile 
away. 


AlUOATORS  lOVE  SUNSHINE 

Alligators  love  to  bosk  in  the  sun,  reserving  most  of  their  feeding  activities  for  night- 
time. They  favor  temperatures  of  between  75°  and  85"  Fahrenheit;  a  temperature 
over  100°  would  be  fatal  to  them.  An  alligator  occasionally  uses  its  powerful  tail 
to   knock  down   its   prey.   As  a   rule,   it  tries  to   keep   away  from   humcn    baing*. 


SJ22  ]  Snakes  and  Frogs  and  Their  Relatives 

Alligators  in  the  Home:  An  alligator  is  an  unlikely  but  not  im- 
possible pet.  It  is  not  suited  to  captivity  and  seldom  lives  more 
than  a  couple  of  years  away  from  its  natural  surroundings.  How- 
ever, it  is  occasionally  possible  to  obtain  young  'gators  and— 
judging  from  inquiries  to  zoos  and  museums  about  their  care— a 
number  of  people  do  cope  with  the  problem  of  keeping  an  alli- 
gator in  the  home. 

A  little  alligator,  like  other  reptile  pets,  must  be  kept  in  a 
consistently  warm  temperature  with  plenty  of  sunshine,  and  with 
shade  always  available.  Its  cage  must  be  kept  dry  and  clean  and 
furnished  with  a  pan  of  water.  Feeding  it  once  or  twice  a  week 
is  enough.  Raw  fish  or  bits  of  meat  should  be  offered  on  a  moving 
stick,  preferably  to  one  side  of  the  'gator's  head. 

Frogs 

Naturalists  call  the  frog  an  "amphibian"— a  creature  that  lives 
a  double  life.  This  is  a  good  name  for  the  frog,  as  it  divides  its 
time  between  land  and  water.  It  has  characteristics  in  common 
with  fish:  It  is  cold-blooded,  and  it  lays  its  eggs  in  the  water.  In  other 
respects  it  is  akin  to  reptiles,  which  are  also  cold-blooded  but 
are  able  to  live  on  dry  land.  Thus  the  frog,  along  with  the  toad, 
newt,  salamander,  and  other  amphibians,  is  a  "connecting  link" 
between  the  two  great  cold-blooded  groups— fish  and  reptiles. 

The  Hobby  of  Collecting  Frogs*  Eggs 

For  generations  children  have  sought  frogs'  eggs,  and  suc- 
cessful hunters  still  bring  them  home  to  observe  their  development 
in  an  aquarium.  Collecting  eggs  should  not  be  encouraged,  as  it 
makes  inroads  on  the  frog  population.  However,  the  ability  to 
i-ecognize  eggs  adds  interest  to  a  springtime  expedition  to  a  pond 
or  quiet  stream. 

If  a  child  is  serious  about  exploring  nature  and  particularly 
anxious  to  watch  tadpole  development,  it  is  important  to  know 
what  species  he  is  collecting;  the  time  required  for  development 
of  the  eggs  varies  widely  according  to  the  species  of  the  parent 
frogs.  Wood  frogs  take  on  adult  form  the  same  season  the  eggs 
are  laid;  green  frog  tadpoles  usually  do  not  grow  into  frogs  until 


Snakes  and  Frogs  and  Their  Relatives  [223 

the  following  summer;  bullfrogs  may  remain  in  a  tadpole  state 
for  two  or  three  years  I 

How  THE  Eggs  Develop 

We  find  frog  eggs  laid  in  a  transparent  protective  jelly. 
The  shape  of  the  jelly  mass  is  one  clue  to  the  species;  the  date 
it  is  discovered  is  another.  The  eggs  of  leopard  or  wood  frogs, 
for  example,  may  be  found  by  the  first  of  April;  those  of  the 
green  frog  do  not  appear  until  a  bit  later,  and  the  bullfrog  may 
not  lay  before  July.  The  leopard  frog's  egg  masses  are  in  the  form 
of  a  flattened  sphere;  those  of  the  wood  frog  are  round  masses. 

In  the  earliest  stages,  as  the  original  single  cell  gradually  divides 
into  many,  you  can  follow  the  egg's  development  only  with  the 
aid  of  a  magnifying  glass.  It  is  only  when  the  embryo  begins  to 
lengthen  that  it  can  be  easily  seen  with  the  naked  eye.  After  five 
or  six  days  the  embryo  has  a  tadpole  form,  but  it  is  still  inside 
the  jelly  mass.  About  the  ninth  day  the  tadpole  breaks  loose  from 
its  protective  covering. 

How  A  Tadpole  Grows 

The  Development  of  the  Head:  At  first  the  tadpole  is  so  shapeless 
that  the  only  way  to  know  head  from  tail  is  to  observe  the  direc- 
tion in  which  it  swims— the  head  naturally  goes  first.  But  soon 
the  head  grows  larger.  Instead  of  a  mouth  the  tadpole  has  a  V- 
shaped  raised  sucker  by  which  it  attaches  itself  to  water  weeds. 
Later  this  gives  way  to  a  small  round  mouth  provided  with  horny 
jaws.  As  the  tadpole  grows,  the  mouth  gets  wider  and  larger. 

How  the  Tadpole  Breathes:  When  you  observe  the  tadpole  you 
see  little  tassel-like  gills  appear  on  either  side  of  the  throat. 
Blood  passing  through  the  gills  is  purified  by  coming  in  contact 
with  the  oxygen  in  the  water.  Later  the  feathery  gills  disappear 
as  a  membrane  grows  down  over  them,  and  they  function  inside 
the  body  instead  of  externally.  Water  taken  in  through  the  nostrils 
passes  through  an  opening  in  the  throat,  on  over  the  gills,  and 
out  through  a  little  opening,  or  breathing  pore,  at  the  left  side 
of  the  body.  This  breathing  pore  may  easily  be  seen  in  larger 
tadpoles. 


224  ]  Snakes  and  Frogs  and  Their  Relatives 

The  Legs  and  Tail  Develop:  A  tadpole's  flat  tail,  bordered  by  a 
fin,  is  a  valuable  swimming  aid.  But  in  a  matter  of  weeks—the 
time  depends  on  the  species— the  first  sign  of  legs  foreshadows  the 
decline  of  the  tail's  usefulness.  The  hind  legs  appear  first  as  mere 
bumps  but  soon  push  out  completely  with  five  webbed  toes. 

Meanwhile  the  front  legs  show  just  in  back  of  the  head,  the 
left  one  pushing  out  through  the  breathing  pore.  The  front  feet 
have  only  four  toes  apiece  and  are  not  webbed;  they  are  used  for 
balancing,  whereas  the  back  feet  serve  for  thrusting  forward. 
While  these  changes  are  taking  place,  the  tail  is  becoming 
absorbed  by  the  body. 

First  Amphibian  Landing:  Young  frogs  do  not  always  wait  for 
the  completion  of  their  adult  form  before  venturing  on  land.  In 
late  spring  or  early  summer  you  may  see  one  hopping  about,  still 
wearing  its  stumpy  little  tail.  From  then  on  the  frog  is  primarily 
a  land  animal,  though  the  members  of  most  species  stay  near 
water,  ready  to  jump  in  at  a  sign  of  danger  or  simply  to  refresh 
themselves. 

The  frog  puts  its  tongue  to  good  use.  Hinged  to  the  front  of 
the  lower  jaw,  the  tongue  can  be  thrust  far  out  of  the  mouth  to 
capture  insects  on  its  sticky  surface. 

Biggest  and  Smallest  Frogs 

The  bullfrog  is  the  giant  among  North  American  frogs. 
Eight  inches  is  about  its  maximum  length.  Its  head  is  usually  a 
bright  green,  the  upper  part  of  its  body  green  also  but  shading 
to  gray  and  brown,  and  its  underside  is  yellowish. 

Other  identifying  features  are  its  large  eardrums  and  the  con- 
spicuous folds  of  skin  which  run  from  behind  the  eyes  around 
the  eardrums  to  the  front  legs.  The  bullfrog's  deep  voice  is  prob- 
ably better  known  than  its  appearance.  You  may  hear  its  sonorous 
jug-o'-rum  repeatedly  near  lakes  and  ponds  on  summer  evenings. 

Just  as  the  bullfrog  is  a  typical  "voice  of  summer,"  the  little 
tree  frog,  commonly  known  as  the  peeper,  might  be  called  the 
"voice  of  spring."  The  spring  peeper— or,  more  prosaically,  Pick- 
ering's hyla— is  one  of  the  tiniest  of  froglets.  Fully  grown,  it  is  about 
an  inch  longi

its  pond  home.  It  eats  smaller  frogs  of  all  kinds,  fish,  the  nymphs  of  dragonflies, 
other  water   insects,  worms,   and   practically  anything   that  fits   in   its   huge   mouth

THE   "REAL   THING"    IN   CHAMELEONS 

Although  certain  American  lizards  are  popularly  known  as  chameleons,  the  true 
chameleon,  pictured  above,  is  a  native  of  Africa.  One  of  the  most  fantastic  of 
animals,  it  has  a  long,  grasping  tail,  strangely  shaped  limbs,  eyes  that  move  inde- 
pendently of  each  other,  a  head  ornamented  like  some  huge  prehistoric  dinosaur's, 
plus  the  ability  to  change  color  from  moment  to  moment,  to  match  its  background.

TWENTY  THOUSAND  EGGS  AT  A  TIME 

The  bullfrog  gets  its  name  from  Its  sonorous  call.  Though  the  female  lays  as  many 
as  twenty  thousand  eggs  at  one  time,  the  tadpole  takes  quite  long  (three  years) 
to  develop  into  an  adult.  Protective  coloration  and  unusual  jumping  ability  safe- 
guard the  frog  against  most  enemies;  but  the  demand  for  frogs'  legs  as  a  delicacy 
has  made  inroads  on  our  frog  population. 


Under  the  throat  of  the  male  is  a  thin  membrane  that  swells 
to  surprising  proportions  as  he  blows  air  into  it,  then  closes  the 
openings  to  his  nose  and  forces  the  air  up  and  down  his  gullet. 
As  early  as  March  you  may  hear  the  din  raised  by  a  number  of 
peepers  going  through  their  vocal  gymnastics. 

There  are  several  reasons  why  the  spring  peeper  is  able  to  elude 
most  observers.  Aside  from  its  tiny  size,  it  changes  color  to  blend 
with  its  background.  In  less  than  half  an  hour  the  dark  cross  on 
its  back  can  alter  to  a  mottled  effect,  and  its  body  tone  can  change 
from  a  pale  yellowish  brown  to  leaf-green,  earth-brown,  or  even 
the  brighter  tones  of  flower  petals! 

Another  point  is  that  the  spring  peeper  spends  a  great  deal  of 
time  in  trees,  which  it  can  climb  easily  because  of  its  marvelously 
adapted  toes.  Each  toe  ends  in  a  rounded  disk  that  secretes  a  sticky 
substance  so  effective  that  a  peeper  can  walk  up  a  vertical  pane 
of  glass.

Toads 

Though  most  children  delight  in  catching  frogs,  many  hesitate  to 
touch  a  toad.  They  have  heard  the  old  myth  that  a  toad  is  sure 
to  produce  warts  on  the  hand  that  touches  it.  While  this  much- 
maligned  amphibian  does  have  warts  on  its  back,  it  has  no  power 
to  transfer  them. 

Basis  for  the  "Warf'  Myth:  The  so-called  warts  are  really  glands 
which  secrete  a  disagreeable-tasting  substance.  The  elongated 
swollen  glands  above  and  just  back  of  the  ears  exude  a  milky 
poisonous  substance  when  the  toad  is  seized  by  a  hungry  enemy. 
This  protective  feature  is  entirely  successful  in  some  cases,  but 
many  toads  become  victims  of  snakes  and  other  animals. 
The  Toad  Eats  Its  Skin 

Unlike  the  slippery,  slimy  frog,  the  toad  has  a  perfectly 
dry  skin.  It  is  cold  to  the  touch  because  toads,  like  all  amphibians, 
are  cold-blooded.  Though  the  toad  sheds  its  skin  periodically, 
you  will  never  find  one  of  these  skins  as  you  may  a  snake's  skin. 
The  skin  is  promptly  swallowed  by  the  toad  that  sheds  it! 

How  Toads  Drink  and  Breathe 

The  toad  has  a  very  absorbent  skin.  When  it  is  thirsty  it 
never  drinks  by  mouth;  instead,  it  stretches  out  in  shallow  water 
and  absorbs  moisture  through  its  skin.  Consequently,  if  pools  are 
not  available  and  if  the  atmosphere  is  dry,  the  toad  will  die  in  a 
short  time. 

The  toad's  breathing  technique  is  also  curious.  You  may  notice 
a  steady  pulsation  in  a  toad's  throat  that  results  from  its  swallow- 
ing air.  Lacking  ribs,  it  cannot  inflate  its  chest  to  draw  air  into  its 
lungs  as  we  do. 

How  Toads  Defend  Themselves 

The  toad  is  a  favorite  prey  of  many  larger  animals.  It 
cannot  fight  back,  but  it  is  resourceful  in  trying  to  save  itself. 
Toads  and  frogs  use  the  same  means  of  defense:  Both  are  jumpers 
capable  of  making  long  rapid  jumps.  The  popular  game  "leap- 
frog" is  a  tribute  to  the  extraordinary  jumping  ability  of  the  frog, 
which  has  larger  and  more  muscular  hind  legs.

TRUTH  AND  FICTION  ABOUT  TOADS 

There  is  no  truth  in  the  quaint  superstition  that  "ft  rains  toads"  and  that  "toads 
cause  warts/'  The  truth  about  toads  is  interesting  enough — for  example,  a  toad 
eats  its  skin  after  shedding  it;  it  "drinks"  by  absorbing  moisture  through  its  skin; 
and  it  digs  holes  with  its  hind  feet,  retreating  into  one  of  these  hideouts  on  the 
approach  of  enemies.   It  stays  in  concealment  by  day,  becomes  active   at  night. 


With  both  of  these  amphibians  protective  coloration  is  special- 
ized to  the  point  of  transforming  color  tone  to  blend  with  the 
background.  A  toad  also  has  a  clever  way  of  disappearing.  Instead 
of  squatting  where  it  can  easily  be  seen,  it  kicks  backward  until 
its  body  is  covered  with  earth.  At  the  approach  of  an  enemy,  the 
U)ad  quickly  jerks  its  head  back  letting  earth  tumble  over  its 
head  as  well. 

The  toad  also  knows  how  to  become  inconspicuous  by  flatten- 
ing out  its  body  and,  when  actually  trapped,  it  will  **play  dead." 


228]  Snakes  and  Frogs  and  Their  Relatives 

Finally,  if  all  these  ruses  fail  and  it  is  seized  by  an  enemy,  it 
emits  a  terrified  noise. 

Where  to  Find  Toads 

These  amphibians  are  rarely  out  in  the  open  during  the 
daytime,  and  a  child's  best  chance  to  observe  their  habits  is  to 
keep  one  as  a  pet.  They  go  abroad  mostly  at  nighttime,  hunting 
for  slugs,  worms,  and  insects;  most  of  the  day  they  remain  in 
hiding. 

Toads  frequent  cool  damp  places;  in  suburban  areas  you  may 
discover  one  under  a  porch  or  dug  in  under  a  sidewalk.  In  the 
fall  they  burrow  deep  into  the  ground  to  hibernate.  When  they 
awaken  in  the  spring  they  make  their  way  to  a  pond  to  breed 
and  lay  their  eggs. 

How  Toads*  Eggs  Develop 

The  eggs  of  the  toad,  like  frogs'  eggs,  are  laid  in  a  trans- 
parent jelly-like  substance,  but  they  can  be  identified  by  their 
form.  The  toad's  eggs  are  laid  in  long  strings,  instead  of  in  masses 
like  the  frog's  eggs.  Changes  in  toads'  eggs  take  place  rapidly. 
Tadpoles  may  emerge  only  four  days  after  the  eggs  are  laid;  only 
a  few  weeks  later  the  tadpoles  have  developed  into  adults. 

The  toads  are  still  very  small,  however,  and  continue  to  grow 
as  adults— in  contrast  to  frogs,  which  attain  much  of  their  adult 
size  while  still  in  the  tadpole  stage.  The  final  size  achieved  by  a 
toad  varies  with  the  species.  One  kind,  native  to  the  Southwest, 
sometimes  measures  six  and  a  half  inches  in  length;  a  little  green 
toad  that  lives  on  the  grassy  flatlands  of  the  Southwest  is  no  more 
than  an  inch  and  a  half  long. 

Salamanders 

A  most  likely  time  to  make  the  acquaintance  of  the  little 
amphibians  known  variously  as  salamanders,  newts,  or  efts,  is 
shortly  after  a  spring  or  summer  rain.  If  you  are  walking  along  a 
country  road  or  woodland  path,  you  may  not  even  have  to  look 
for  them:  They  are  out  in  the  open  enjoying  the  newly  fallen 
moisture. 


Snakes  and  Frogs  and  Their  Relatives  [229 

At  other  times  you  may  find  them  under  stones  or  rotting  logs, 
in  wet  crevices  along  a  brook,  and  even  in  the  water.  All  sala- 
manders must  stay  in  places  where  their  skin  will  not  become 
too  dry— though  some  prefer  more  water  than  others  do. 

Frequently  when  a  child  discovers  a  salamander  he  calls  it  a 
lizard;  and  it  does  strongly  suggest  the  small  reptile.  However, 
there  are  several  distinguishing  features.  The  salamander's  skin 
may  be  moist,  slimy,  or  even  dry  and  rough;  but  it  is  never  covered 
with  scales,  as  is  the  skin  of  a  lizard.  No  salamander  has  claws, 
whereas  you  will  find  these  on  the  toes  of  a  lizard. 

The  Red  Eft 

There  is  quite  a  bit  of  variety  in  the  appearance  of  sala- 
manders and  in  the  pattern  of  their  lives.  The  red-backed  species

THE  ELUSIVE  TIGER  SALAMANDER 

This  salamander  gets  its  name  from  its  colors  (yellow  splotches  cover  its  brown  body), 
and  reaches  a  length  of  ten  inches.  Like  most  of  its  kind,  it  is  an  elusive  creature, 
burrowing  by  day,  and  coming  out  at  night  to  forage  for  food.  All  salamanders 
have  smooth  skins,  in  contrast  to  the  scaly  bodies  of  lizards. 


230  ]  Snakes  and  Frogs  and  Their  Relatives 

does  not  even  conform  to  the  usual  amphibian  program  of  a  land- 
and-water  existence  and  spends  its  entire  life  on  land. 

One  of  the  most  commonly  seen  salamanders  is  the  red  eft.  It 
begins  its  adventurous  existence  in  a  pond  or  stream,  where  it 
hatches  from  an  egg  laid  on  a  water  plant.  The  next  few  months 
it  dwells  in  the  water;  it  is  an  expert  swimmer,  has  gills,  and 
breathes  like  a  fish.  By  the  middle  of  August  the  eft  has  lost  its 
gills,  developed  legs,  and  in  all  respects  is  ready  for  life  ashore. 
About  this  time  it  takes  on  a  bright  orange  hue. 

For  the  next  two  and  a  half  years  the  red  eft  lives  on  land, 
usually  frequenting  damp,  shady  places  and  hiding  under  leaves 
or  moss.  Then,  though  it  may  have  wandered  far  away  from  water, 
it  starts  traveling  purposefully  until  it  reaches  a  pond  or  stream. 

After  returning  to  its  native  element  the  eft  undergoes  more 
changes:  Its  color  becomes  olive-green  above  and  buff  below, 
while  its  tail  develops  a  keel  that  extends  along  its  back.  Only 
now  does  it  seek  a  mate,  and  its  remaining  years  are  spent  as  a 
water  animal.  In  this  final  water  stage  the  red  eft  is  frequently 
called  a  newt— a  common  name  for  this  type  of  salamander. 

The  Care  of  Amphibians 

Collecting  frogs  or  other  amphibians  and  keeping  them  for  a 
while  is  a  fine  seasonal  hobby  for  children.  However,  it  is  impor- 
tant to  first  inquire  of  the  conservation  department  of  your  state 
for  regulations  about  which  kinds  of  frogs  may  be  collected  and 
when. 

How  TO  Catch  a  Frog 

A  stout  collecting  net  is  a  useful  aid  in  catching  the  elusive 
frog  which  you  are  most  likely  to  find  in  a  swamp  or  shallow  pond. 
Extend  the  net  slowly  and  quietly  toward  and  under  a  pros 
pective  captive.  With  a  quick  upward  and  outward  movement 
you  may  succeed  in  snaring  the  frog.  It  should  then  be  trans- 
ferred to  a  suitable  container,  such  as  a  wet  burlap  bag,  for 
carrying  home.

Living  Quarters  for  the  Amphibian 

You  can  turn  an  aquarium  into  a  satisfactory  home  for 
small  specimens  of  frogs,  toads,  or  salamanders.  A  screen  top  made 
secure  around  the  edges  will  prevent  their  escape.  For  frogs  and 
salamanders  the  aquarium  should  be  about  one-third  full  of 
water,  with  stones  piled  high  at  one  end  to  give  the  amphibians  a 
place  to  land.  Toads  need  far  less  water;  for  them,  the  bulk  of  the 
cage  should  be  dry. 

It  is  important  to  bring  home  some  water  from  the  pond  where 
the  frogs  are  caught,  using  it  for  them  while  they  are  in  your 
care.  Tap  water  is  often  purified  with  chemicals  that  are  fatal 
to  these  animals.  The  water  in  the  amphibian's  quarters  must  be 
changed  often  and  kept  perfectly  clean;  uneaten  food  particles 
should  be  removed  daily. 

How  TO  Feed  an  Amphibian  Pet 

Live  insects— such  as  flies  or  bugs— and  earthworms  are  a 
good  diet  for  most  amphibians.  Sometimes  a  captive  will  nibble 
at  small  bits  of  food,  and  you  can  experiment  to  find  the  diet  that 
appeals  most  to  it.  If  it  does  not  respond  to  your  attempts,  it 
should  be  given  its  freedom  near  the  locality  where  it  was  found. 

Sometimes  it  may  prove  practical  to  grow  your  own  insects; 
this  is  what  a  boy  of  my  acquaintance  did  who  was  keeping  a 
dozen  salamanders  in  a  large  terrarium.  In  it  he  placed  a  bottle 
containing  a  few  pieces  of  banana.  Fruit  flies  bred  rapidly  there, 
and  as  they  started  to  fly  out  they  were  snapped  into  the  ready 
mouths  of  the  salamanders. 

Frogs  and  salamanders  should  always  be  picked  up  by  placing 
your  hand  under  their  body.  They  are  then  less  apt  to  get  away, 
and  such  handling  is  far  less  injurious  than  encircling  them  with 
warm,  dry  skin.  The  heat  of  the  human  hand  can  kill  a  very  small 
amphibian.  Thus  we  see  that  even  in  the  case  of  seemingly  petty 
details  we  have  to  bear  in  mind  the  basic  physical  make-up  of 
the  amphibian,  and  the  possible  consequences  of  not  heeding  its 
requirements-

There  is  another  way  of  looking  at  them,  though.  The  lives

ties" of  nature  which  so  delight  all  of  us  are  found  in  striking 
abundance  among  the  insects. 

Some  of  them  are  skillful  engineers  and  manufacturers.  Bees 
and  ants  live  in  societies  complex  enough  to  rival  those  of  man- 
kind. One  insect,  the  doodlebug,  always  walks  backward!  The 
queen  of  a  tropical  species  of  termites  may  produce  ten  million 
offspring  in  her  lifetime.  There  are  wasps  that  keep  their  food 
fresh  over  a  period  of  time— just  as  successfully  as  we  keep  ours 
in  a  refrigerator— by  injecting  a  fluid  which  paralyzes  the  nerves 
of  their  victims  without  producing  death.  Then  the  wasps  store 
the  bodies  until  they  are  needed  as  food. 

Many  of  our  common,  everyday  insects  become  objects  of 
wonder  if  we  examine  their  way  of  life;  and,  as  they  live  in  city, 
town,  and  country,  we  can  enjoy  hours  of  fascinating  observation 
without  troubling  to  go  far  afield.

The  Wonderful  Ways  of  Insects  and  Spiders  [233 

What  is  An  Insect? 

People  have  a  habit  of  referring  to  every  small,  creeping  animal 
as  an  insect.  However,  many  creatures  that  are  so  called  do  not 
belong  to  the  classification  of  insects.  Spiders  are  not  insects— nor 
are  worms  and  centipedes.  How,  then,  do  we  really  determine 
what  is  or  isn't  an  insect? 

An  insect  in  the  adult  stage  has  three  pairs  of  legs— no  more, 
no  less.  It  also  has  three  distinct  parts  to  its  body— the  head,  the 
thorax,  and  the  abdomen.  And  all  insects  have  a  shell-like  covering 
to  protect  their  bodies. 

How  Insects  Are  Able  To  Move 

Insects  have  no  inside  bone  structure  to  help  them  move 
as  our  bones  help  us;  but  movement  is  possible  for  them  because 
each  end  of  their  muscles  is  attached  to  the  hard  outer  covering 
that  serves  as  an  "outside  skeleton."  A  muscle,  for  example,  which 
acts  to  move  a  leg  forward  has  one  end  attached  to  the  hard  cover- 
ing of  the  leg  and  the  other  end  attached  to  the  covering  of  the 
thorax  in  front  of  the  legs.  When  this  muscle  contracts,  it  pulls 
the  two  solid  attachments  closer  together— and  the  leg  moves  for- 
ward. 

It  might  seem  impossible  for  a  creature  encased  in  a  rigid  cov- 
ering to  bend.  However,  the  insect  has  joints  in  places  where  the 
body  wall  is  flexible.  That  is  why  the  creature  can  bend,  some- 
what as  a  knight  of  old  could  bend  because  his  suit  of  heavy  armor 
was  jointed. 

The  Lowly  Bug 

Frequently  the  term  "bug"  is  mistakenly  used  for  "insect." 
Though  all  bugs  are  insects,  in  the  scientific  sense,  not  all  insects 
are  bugs.  Bugs  belong  to  a  specific  group  that  varies  within  itself 
in  many  respects;  but  all  bugs  are  alike  in  having  piercing,  suck- 
ing mouth  parts.  The  group  includes  the  giant  water  bugs  (also 
known  as  electric-light  bugs  because  the  adults  often  fly  about 
electric  lights) ,  squash  bugs  and  bedbugs. 


234  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

Millions  of  Kinds  of  Insects 

The  creatures  that  rightly  bear  the  name  "insects"  are 
included  in  an  astoundingly  huge  number  of  species.  We  already 
know  of  hundreds  of  thousands  of  different  kinds,  and  scientists 
believe  that  the  total  number  of  kinds  will  eventually  be  reckoned 
in  the  millions!  There  are  more  species  of  insects  than  all  other 
species  of  animals  added  together.  More  than  any  other  kind  of 
creature,  insects  may  he  regarded  as  man's  competitor  for  mastery 
of  the  earth. 

The  destruction  of  farm  crops,  stored  products,  and  wooden 
buildings  by  insects,  and  their  injury  to  the  health  of  human 
beings  by  spreading  disease,  is  beyond  calculating.  However, 
millions  of  dollars  are  being  spent  every  year  on  research,  quaran- 
tine and  control:  The  menace  of  insects  is  far  less  frightening 


HUGE  HORNET  COLONIES 

As  many  as  fifteen  thousand  hornets  may  live  in  a  single  paper-covered  nest.  They 
have  sentinels  posted  at  the  door  to  warn  of  the  approach  of  intruders.  Hornets 
are  irritated  by  the  presence  of  marauders  and  all  too  ready  to  sting  near  their 
nest.  However,  they  are  much  less  likely  to  sting  when  away  from  it.

to  us  than  it  was  to  our  parents.  Despite  all  the  havoc  that  insects 
wreak,  they  are  actually  of  enormous  value  to  us  in  some  ways. 
Insects  play  a  vital  role  by  pollinizing  many  plants  on  which 
we  depend  for  food  for  ourselves  and  our  domesticated  animals; 
and  many  birds  as  well  as  fish  would  disappear  if  they  were  de- 
prived of  insect  food. 

How  Insects  Develop  ^^ 

The  Magic  of  Metamorphosis 

The  child  who  observes  a  crawling  caterpillar  change  into 
a  winged  butterfly  is  enthralled  by  a  mystery  which  seems  one  of 
nature's  greatest  wonders.  This  is,  however,  only  one  of  several 
patterns  of  growth  that  we  find  among  insects.  It  involves  four 
different  forms.  Butterflies,  moths  and  others  that  grow  this  way 
are  said  to  have  a  "complete  metamorphosis."  (The  word  is  from 
the  Greek  and  means  "change  of  form.") 

The  first  form  is  the  e^^',  the  next  is  the  larva.  Then  comes  the 
pupal  stage,  a  period  of  relatively  quiet  resting.  Finally  the  pupa 
develops  into  the  adult.  The  larva  of  a  butterfly  we  commonly 
call  a  caterpillar;  the  term  for  the  pupa  is  "chrysalis."  The  larva 
of  a  fly,  you  may  know  as  a  "maggot";  that  of  a  bee  or  a  beetle, 
as  a  "grub." 

Incomplete  Metamorphosis 

Another  type  of  insect  growth  is  called  an  "incomplete 
metamorphosis"  because  the  insects  do  not  go  through  any  strik- 
ing change  in  form  during  their  growth  after  the  egg  stage.  They 
do,  however,  gradually  change  their  proportions.  The  young  of 
this  group,  known  as  "nymphs,"  are  like  adults  in  most  respects. 
They  eat  the  same  food  and  are  much  the  same  in  appearance 
and  behavior.  The  grasshopper  is  a  well-known  member  of  this 
group. 

In  the  case  of  some  water-dwelling  nymphs,  such  as  the  young 
of  the  dragonfly,  we  see  a  great  change  when  the  gilled  nymph 
becomes  an  adult;  but  the  metamorphosis  is  still  considered 
"incomplete." 


236  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

The  silverfish  illustrates  still  another  type  of  growth.  It  has  no 
metamorphosis;  the  general  body  form  does  not  change  notice- 
ably from  the  time  it  leaves  the  egg  until  it  is  fully  grown. 

All  insects  shed  their  skeletal  coverings  a  number  of  times 
while  they  are  still  growing. 

How  Insects  See,  Hear,  and  Feel 

Eyes  With  Thousands  of  Facets 

Occasionally  among  published  photographs  you  may  see 
a  strange-looking  object  suggesting  a  mosaic  of  diamonds.  It 
proves  to  be  the  compound  eye,  greatly  magnified,  of  an  insect. 
The  photograph  makes  a  curiously  intricate  pattern  of  what  are, 
in  eflEect,  many  tiny  eyes  set  close  together,  somewhat  like  the 
cells  of  a  honeycomb.  An  adult  insect  has  one  of  these  compound 
eyes  on  each  side  of  its  head. 

The  six-sided  areas  into  which  the  eyes  are  divided  are  known 
as  "facets."  The  compound  eyes  of  ants  and  other  insects  that 
live  on  the  ground  have  only  a  few  facets,  and  their  vision  is  not 
sharp.  The  eyes  of  dragonflies  and  other  keen-eyed  species  may 
have  thousands  of  facets! 

There  are  also  many  species  with  simple  eyes— three  of  them— 
situated  between  the  compound  eyes.  The  simple  eyes  are  so 
tiny,  however,  that  you  will  need  a  magnifying  lens  to  find  them. 

Insects  can  perceive  mass  and  motion,  light  and  darkness  and, 
to  a  certain  extent,  they  can  distinguish  colors. 

Ears  Anywhere  and  Everywhere 

Whenever  hearing  equipment  has  been  discovered  in  cer- 
tain kinds  of  insects,  it  has  been  found  on  rather  unconventional 
parts  of  the  body.  The  grasshopper,  for  example,  has  an  oval 
membrane  sensitive  to  sound,  and  it  is  located  on  the  side  of  the 
first  abdominal  segment.  Crickets,  ants,  and  katydids  have  hearing 
organs  on  their  front  legs,  and  the  male  mosquito  hears  through 
its  antennae,  or  ''feelers."

The  Insect's  Detecting  Equipment 

The  antennae  vary  in  shape  and  degree  of  complexity 
according  to  species.  The  segments  which  make  up  the  antennae 
vary  in  number— and  in  form  as  well.  The  grasshopper's  antennae 
may  have  more  than  twenty  segments,  whereas  the  common 
housefly  has  only  three  stubby  segments.  An  insect  uses  its  an- 
tennae to  investigate  its  surroundings,  and  in  many  species  these 
feelers  are  related  in  some  degree  to  the  sense  of  smell.  The 
antennae  are  attached  to  the  head— in  front  of,  or  between,  the 
eyes. 

How  Insects  Eat  and  Breathe 

When  we  learn  about  the  mouth  parts  of  insects  we  realize 
that  there  is  no  more  dramatic  example  of  the  way  nature  varies 
the  forms  of  its  creatures  to  suit  special  needs. 

Crushing  and  Sucking:  The  sharp  strong  jaws  of  the  ground 
beetle  are  excellently  adapted  to  crush  and  eat  caterpillars.  The 
big  brown  squash  bug  and  others  use  a  sucking  tube  to  take 
juice  from  plants;  bedbugs  have  a  similar  mechanism  for  taking 
blood  from  animals.  As  for  butterflies  and  other  insects  that 
extract  nectar  from  flowers,  they  use  a  long  tube,  or  tongue,  which 
at  other  times  is  tightly  coiled  beneath  the  head. 

Grasshoppers  Bite  Their  Food:  The  grasshoppers  and  other  biting 
insects  have  an  upper  lip  and  an  underlip,  with  two  pairs  of 
jaws  between  them.  If  you  look  at  a  grasshopper  through  a 
magnifying  lens  you  will  see  that  the  upper  pair  of  jaws  (the 
mandibles)  are  somewhat  heavier  than  the  lower  pair  (the 
maxillae). 

On  these  lower  jaws  and  on  the  lower  lip  there  are  feelers 
or  tasters  called  "palpi."  The  taste  buds— comparable  to  our 
own— on  the  tips  of  the  palpi  enable  the  grasshopper  to  taste  its 
food  before  biting  it.  Though  mandibles  function  somewhat 
as  human  jaws  do,  they  work  from  side  to  side  instead  of  up 
and  down. 


238  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

Breathing  Without  Lungs:  Insects  do  not  breathe  the  way  we  do. 
If  you  examine  almost  any  insect  closely,  you  will  discover  a 
series  of  tiny  openings  along  the  sides  of  the  body.  These  are  the 
"spiracles"  or  breathing  holes  through  which  air  passes  into  the 
insect's  body. 

The  spiracles  lead  into  a  system  of  thin-walled  tubes  which 
distribute  the  air  throughout  the  body.  As  the  insect's  blood 
comes  into  contact  with  these  tubes,  it  becomes  purified  as  your 
blood  does  when  it  bathes  the  air  tubes  of  your  lungs.  In  the  case 
of  grasshoppers  and  a  number  of  other  insects  naturalists  have 
discovered  that  some  of  the  spiracles  are  used  exclusively  for 
inhaling,  the  others  only  for  exhaling. 

The  Delicate  Structures  of  Legs  and  Wings 

We  have  already  learned  that  an  insect's  body  has  three  main 
parts:  the  head,  the  thorax,  and  the  abdomen.  Each  of  these  three 
parts  is  made  up  of  ringlike  segments  that  have  grown  together. 
The  thorax,  or  middle  region,  is  made  up  of  three  segments,  each 
bearing  a  pair  of  legs.  (You  will  recall  that  all  insects  have  three 
pairs  of  legs.) 

The  insect's  front  legs  are  attached  to  the  first  segment.  The 
front  wings— if  there  are  any— and  the  middle  legs  are  attached  to 
the  second  segment.  The  hind  legs— and  the  hind  wings,  if  they 
are  present— are  attached  to  the  third  segment. 

If  you  spread  apart  a  grasshopper's  four  wings,  you  will  find 
that  the  upper  ones  are  long  and  narrow,  while  the  broad  lower 
wings  rest,  folded  like  fans,  beneath  them.  If  you  feel  their  tex- 
ture you  will  discover  that  the  lower  pair  are  far  more  delicate 
than  the  upper  wings  which  protect  them. 

Once  insects  acquire  wings  they  stop  growing.  You  may  see 
little  flies  and  big  flies,  but  they  belong  to  different  species;  the 
little  ones  are  never  going  to  "catch  up"  and  be  big  ones. 

The  legs  of  all  insects  are  jointed  and  made  up  of  about  ten 
segments— though  the  number  and  size  vary  with  different  kinds 
of  insects.  On  many  insects  the  last  segment  bears  one  or  two  claws.

Some  Popular  Insects 

Butterflies— Insects  with  Glamour 

These  lovely  winged  creatures  seem  a  special  gift  of  nature 
to  children.  Many  a  boy  who  has  been  oblivious  to  outdoor  beauty 
is  captivated  by  the  sight  of  a  colorful  butterfly  perched  on  a 
bright  flower.  Some  children  go  further  than  merely  admiring 
the  appearance  of  butterflies;  they  become  absorbed  in  the  hobby 
of  collecting  them.  Taken  in  the  caterpillar  stage,  these  insects 
may  be  observed  through  their  metamorphosis  into  winged  adults. 
Later  on  the  adult  insects,  captured  and  mounted,  make  home 
exhibits  that  are  a  delight  to  the  eye. 

The  collector  must  handle  his  delicate  captives  with  care. 
(There  will  be  more  about  this  later  on.)  Even  with  careful 
handling,  some  fine  colored  dust  comes  off  the  butterflies  onto 
his  fingers.  If  he  could  examine  this  dust  under  a  powerful 
microscope,  he  would  see  that  it  is  made  up  of  tiny  scales.  These 
cover  the  insect's  wings,  overlapping  like  shingles,  and  they  are 
often  responsible  for  the  striking  pattern  and  brilliant  coloring. 

There  is  wide  variety  in  the  size,  shape,  and  habits  of  different 
kinds  of  butterflies.  The  caterpillars  are  equally  varied:  They  may 
be  hairy,  naked,  or  covered  with  spines.  Most  caterpillars  eat  their 
own  special  choice  of  leaves  and  will  starve  to  death  if  they  are 
given  the  wrong  kind. 

The  Beautiful  Black  Swallowtail:  This  swallowtail  is  one  of  the 
loveliest  butterflies  you  are  likely  to  find.  It  lives  in  almost  all 
parts  of  the  United  States  and  frequents  gardens,  sipping  nectar 
from  the  blossoms.  In  meadows  it  is  most  likely  to  be  seen  on 
thistles  or  the  orange-flowered  milkweed.  Two  projections  from 
the  margins  of  its  hind  wings,  which  are  responsible  for  its  popular 
name,  make  it  easy  to  identify.  Its  color  is  velvety  black,  with 
rows  of  yellow  spots;  the  hind  wings  have  metallic  blue  splashes. 
The  female  is  larger  than  her  mate,  and  though  she  has  more 
blue  on  her  wings,  the  yellow  markings  on  his  hind  wings  are 
more  vivid.

The  Wonderful  Ways  of  Insects  and  Spiders 


COLLECTOR'S  PRIZE 

The  tiger  swallowtail  butterfly  has  wings  that  are  beautifully  striped  in  black  and 
yellow.  It  gets  its  name  from  the  tail-like  extensions  of  its  hind  wings.  While  it 
visits  many  flowers,  it  is  partial  to  thistle  and  milkweed.  The  caterpillar  of  this 
butterfly  is  famous  for  a  repulsive  stench  it  produces  to  discourage  enemies,  par- 
ticularly hungry  birds.  It  is  also  noted  for  two  large  eyespots  at  front  end. 


From  Egg  to  Caterpillar:  A  black  swallowtail  deposits  her  eggs  on 
the  leaves  of  carrots,  parsnips,  or  parsley.  Each  tgg  looks  like  a 
tiny  drop  of  honey.  By  the  end  of  ten  days,  the  honey-colored 
eggs  have  turned  almost  coal  black,  and  spiny  little  caterpillars 
make  their  appearance.  Each  caterpillar  at  once  eats  the  shell  of 
the  ^gg  from  which  it  hatched,  then  continues  feeding  on  the  leaf 
where  it  was  originally  placed. 

As  the  caterpillar  grows  it  sheds  its  skin  from  time  to  time, 
and  with  each  molt  it  changes  its  size  and  coloring  until  it  has 
become  a  "carrot  worm."  Now  it  is  about  two  inches  long  and 
strikingly  colored  in  green,  black,  and  yellow.  If  you  poke  a 
finger  at  one  of  these  creatures,  it  will  thrust  out  brilliant  orange 
horns  that  give  off  a  disagreeable  smell.  This  odor  proves  a  most 
effective  defense  against  birds.

The  Chrysalis  Emerges  from  the  Silken  Halter:  If  you  bring  one 
of  these  caterpillars  indoors  or  manage  to  keep  it  under  close 
observation  in  some  other  way,  you  will  in  due  course  see  one  of 
those  wonders  of  nature  that  never  seem  commonplace  no  matter 
how  often  you  may  observe  them.  One  day  you  will  see  the  cater- 
pillar spin  a  button  of  silk  against  a  solid  support.  (Out-of-doors, 
the  lower  edge  of  a  fence  rail  is  a  favorite  place.) 

The  caterpillar  grasps  this  button  firmly  with  its  hind  prop-leg. 
Then  it  spins  a  strong  loop  of  silk,  fastening  both  ends  to  the 
same  support,  and  finally  it  thrusts  its  head  inside  the  silken 
halter.  Thus  supported,  it  starts  to  shed  its  last  caterpillar  skin, 
and  we  see  a  soft  pale-green  pupa,  or  chrysalis,  beginning  to 
emerge. 

Now  comes  a  moment  crucial  for  its  survival:  The  chrysalis 
releases  its  hold  on  the  little  silk  button,  relying  completely  on 
the  halter  for  support  while  it  pushes  off  its  shrunken  skin  and 
inserts  its  hooks  into  the  button.  Sometimes  the  chrysalis  falls  to 
the  ground  during  this  delicate  maneuvering— with  fatal  results. 
The  possibility  of  sudden  death  adds  a  poignant  touch  to  the 
mystery  of  metamorphosis. 

The  Butterfly  Lives  on  Nectar:  The  successful  chrysalis  gradually 
hardens  and  alters  its  colors,  usually  turning  grayish,  dark  green, 
or  tan.  Within  its  shell  the  elements  that  made  up  the  caterpillar 
are  taking  on  the  shape  of  a  butterfly.  Then  one  day,  after  some 
weeks  of  waiting,  you  will  see  the  upper  end  break  open  and  a 
crumpled  mass  of  damp  "velvet"  come  forth.  This  clings  to  a 
support  while  its  wings  unfold,  dry,  and  harden.  In  about  half  an 
hour  the  newcomer  is  ready  for  flight.  As  an  adult,  it  lives  entirely 
on  nectar  (how  fitting!)  and  acts  as  an  efficient  messenger  carry- 
ing pollen  from  one  blossom  to  another. 

The  Migrating  Monarch  Butterfly:  A  common  species  that  chil- 
dren can  easily  learn  to  recognize  is  the  monarch  or  milkweed 
butterfly.  With  its  brilliant  copper-red  color  and  vivid  black 
markings  it  is  quite  conspicuous.  You  can  distinguish  a  similarly 
colored  though  somewhat  smaller  species,  known  as  the  viceroy, 
by  a  black  band  across  the  middle  of  the  hind  wing. 


242  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

Monarchs  are  noted  for  their  migrations.  They  often  gather 
in  large  flocks  in  late  summer  and  then  move  southward.  You  may 
some  day  discover  one  of  these  beautiful  butterflies  with  an 
identification  tag  and  number  in  its  wing.  Many  persons  in  the 
United  States  and  Canada  have  for  several  years  been  marking 
and  releasing  monarchs  in  an  effort  to  increase  the  store  of 
scientific  knowledge  about  them.  The  tag  tells  where  to  send  the 
information  on  your  find,  and  you  may  thus  help  scientists  learn 
the  full  story  of  this  remarkable  traveler. 

The  Hibernating  Mourning  Cloak:  The  habits  of  the  mourning 
cloak— a  brownish  and  yellow  butterfly,  ornamented  with  blue 
spots— are  in  marked  contrast  to  those  of  the  monarch.  The  mourn- 
ing cloak  sleeps  in  hollow  trees  or  crannies  during  cold  weather 
and  is  one  of  the  few  insects  that  hibernate  in  the  adult  stage. 

Flying  Fighters:  For  all  their  ethereal  appearance,  you  may  dis- 
cover by  watching  butterflies  that  they  are  not  at  all  averse  to 
some  very  down-to-earth  fighting.  The  males  of  many  species  will 
try  to  drive  away  any  others  that  encroach  on  territory  they  con- 
sider their  own.  As  a  result,  duels  take  place,  with  the  contenders 
darting  and  dashing  at  each  other,  sometimes  buffeting  their 
wings  to  shreds.  The  red  admiral  and  the  buckeye  are  particularly 
noted  as  scrappers. 

Moths— How  They  Differ  From  Butterflies 

Children  are  much  more  likely  to  become  acquainted  with 
the  caterpillars  of  moths  than  with  the  moths  themselves,  as  these 
winged  insects  (with  few  exceptions)  sleep  by  day  and  fly  only  at 
dusk  or  after  dark.  This  nighttime  schedule  of  activity  helps  us 
to  distinguish  moths  from  butterflies,  as  butterflies  are  abroad 
during  the  day. 

There  are  several  other  features  which,  as  a  rule,  guide  us  in 
telling  a  moth  from  a  butterfly.  When  at  rest,  butterflies  hold 
their  wings  vertically  above  their  bodies  while  moths  extend 
theirs— horizontally,  or  tentlike  over  their  bodies.  A  moth's  body 
is  thicker  and  more  wedge-shaped,  and  its  antennae  are  feathery 
or  finely  tapered.  A  butterfly's  antennae,  though  smooth,  end  in 
knobs  or  thickenings. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  243 

Silk  Manufacturers:  A  moth's  life  pattern  is  much  like  that  of  a 
butterfly,  except  that  the  caterpillars  of  certain  moths  weave  about 
themselves  a  covering  of  silk  which  we  call  a  "cocoon."  Most 
species  of  moth  caterpillars,  however,  dispense  with  the  cocoon. 
When  the  "tomato  worm"  and  the  caterpillar  of  the  sphinx  moth, 
for  example,  are  fully  grown,  they  burrow  in  the  earth  and  there 
become  pupae.  If  you  are  digging  around  the  base  of  a  tree  in  the 
late  fall,  you  may  discover  such  caterpillars. 

By  way  of  contrast,  there  are  moth  caterpillars  that  may  be 
termed  "American  silkworms":  They  produce  strong  lustrous 
silk  rivaling  the  product  of  the  Chinese  silkworms.  The  American 
silk  never  became  a  commercial  success  because  these  creatures 
proved  too  difficult  to  breed  in  large  numbers;  in  addition,  the 
labor  involved  in  processing  their  silk  was  very  costly. 

The  native  silkworms  are  the  caterpillars  of  cecropia,  pro- 
methea,  polyphemus,  and  luna  moths.  Even  sharp-eyed  explorers 
are  not  likely  to  find  these  insects  that  have  a  knack  of  blending 
perfectly  with  the  leaves  on  which  they  rest  and  feed. 

The  Woolly  Bear  Caterpillar— Weather  Prophet:  Sooner  or  later 
nearly  every  child  in  country  surroundings  encounters  the  woolly 
bear  caterpillar,  which  is  conspicuous  because  of  its  thick  coat 
of  hair. 

There  are  many  kinds  of  woolly  bears.  One  species  is  black 
at  the  ends  with  a  middle  band  of  brown.  According  to  popular 
belief,  you  can  forecast  the  weather  by  the  size  of  this  band.  With 
the  arrival  of  the  fall,  if  the  band  is  wide— that  is,  if  it  measures 
half  the  body  length  or  more— on  many  woolly  bears,  a  mild 
winter  is  predicted.  By  the  same  token,  if  most  woolly  bears  have 
narrow  bands,  we  are  told  that  the  coming  season  will  be  severe. 
Scientists  have  not  yet  said  the  last  word  on  the  reliability  of  this 
belief. 

You  may  often  discover  woolly  bears  along  the  roadside  in  the 
bright  fall  sunshine.  If  you  pick  one  up,  it  has  the  defensive 
resource  of  rolling  itself  into  a  ball— a  trick  that  it  also  uses  to 
make  itself  less  attractive  to  a  hungry  bird. 


244  ]  ^^^  Wonderful  Ways  of  Insects  and  Spiders 

Woolly  Bears  As  Pets:  If  your  child  brings  home  a  woolly  bear  for 
a  pet,  it  must  be  kept  out-of-doors  in  a  sheltering  wooden  box  at 
ordinary  temperatures.  Keeping  the  creature  in  a  warm  room  is 
likely  to  prove  fatal  to  it.  During  late  summer  it  feeds  on  grass, 
clover,  and  other  leaves;  with  the  onset  of  fall  it  has  reached  its 
full  growth  and  requires  little  in  the  way  of  food. 

After  sleeping  the  winter  away,  the  woolly  bear  rouses  in  the 
spring,  eats  a  little  grass,  and  then  starts  to  spin  its  cocoon,  weav- 
ing into  it  the  hairs  from  its  "fur  coat."  The  finished  cocoon 
gives  the  appearance  of  being  made  of  felt.  About  the  end  of 
May  an  Isabella  tiger  moth  appears.  As  the  moth  flies  only  at 
night,  you  are  less  likely  to  become  familiar  with  it  than  with 
the  woolly  bear.  It  is  a  dull  gray  and  tawny  moth  with  a  few  black 
dots  on  its  wings. 

Caterpillars  As  A  Hobby 

Where  To  Look  For  Caterpillars:  The  woolly  bear  is  not  the  only 
caterpillar  that  makes  an  interesting  captive.  Other  larvae  of 
moths  that  you  are  likely  to  find  are  the  leaf-colored  polyphemus 
(often  on  oak  and  birch  trees),  and  the  colorful  cecropia  cater- 
pillar, green  with  bluish  tint  and  marked  with  yellow,  blue,  and 
red. 

Collecting  butterfly  caterpillars  is  simple  if  you  know  the  right 
hunting  grounds.  Tiger  swallowtail  caterpillars  are  most  com- 
monly found  on  wild  cherry  trees;  cabbage  butterfly  caterpillars 
on  cabbage;  monarchs  on  milkweed  plants;  and  viceroys  on  poplar 
and  willow  trees.  In  hunting  caterpillars  it  is  not  only  helpful 
to  know  the  plants  on  which  they  feed;  it  is  also  advisable  to  take 
some  of  the  leaves  to  feed  your  captives  their  favorite  food. 

Providing  Living  Quarters:  You  can  make  a  home  for  caterpillars 
from  a  shoe  box  or  a  small  wooden  box  or  any  other  kind  of  box 
of  convenient  size.  If  any  of  your  captives  are  the  kind  that  change 
into  a  chrysalis  in  the  earth  rather  than  on  foliage,  it  would  be 
wise  to  put  a  pot  of  dirt  in  the  box. 

You  can  keep  leafy  twigs  fresh  by  placing  them  in  water  in 
the  box,  but  you  need  a  cloth  or  some  other  covering  over  the 
top  of  the  water  container—otherwise  the  caterpillars  might  crawl 


The  Wonderful  Ways  of  Insects  and  Spiders  [  245 

into  it  and  be  drowned.  The  box-cage  should  be  covered  securely 
with  mosquito  netting  or  fine  wire  screening,  and  kept  where  the 
caterpillars  will  have  some  sunlight. 

The  Pleasures  of  Cocoon  Collecting 

In  the  country  you  may  find  the  cocoons  of  some  of  the 
large  silk  moths,  such  as  the  polyphemus,  cecropia,  and  luna.  (The 
beautiful  luna  moth  usually  spins  its  cocoon  between  leaves  on 
the  ground.)  After  the  leaves  have  fallen  in  autumn,  it  is  quite 
easy  to  see  the  brownish  wrappings  which  hold  a  pupa  as  it  hangs 
from  twigs  of  bushes  and  trees. 

Children  enjoy  seeing  the  cecropia's  hammock-shaped  product 
because  of  its  popular  name,  "cradle  cocoon."  It  has  two  walls 
of  silk.  The  inner  wall  is  thin  and  firm;  the  outer  wall— the  one 
you  look  for  when  you  go  cocoon  hunting— is  thick  and  paper-like. 
Between  the  two  walls  there  is  a  mat  of  loose  silk. 

Cocoons  in  the  Home:  When  you  collect  a  hanging  cocoon,  cut 
a  piece  of  the  twig  to  which  it  is  attached.  Later  on,  this  twig  will 
make  the  best  possible  perch  for  the  moth  as  it  emerges  and  waits 
for  its  wings  to  harden. 

If  you  keep  cocoons  in  your  house,  they  must  be  left  in  a  place 
that  is  not  well  heated.   (An  attic  or  cellar  is  fine  for  a  cocoon.) 
If  the  place  is  warm,  the  cocoons  will  hatch  out  before  spring. 
They  should  be  sprinkled  lightly  with  water  about  once  a  week 
to  keep  them  from  getting  dried  out  by  indoor  air. 

From  the  first  of  April  or  thereabouts,  and  for  the  following 
two  months,  you  can  have  an  exciting  time  watching  for  the 
beautiful  winged  insects  to  emerge.  Sometimes  you  are  given 
advance  notice  of  the  event  when  the  end  of  a  cocoon  grows  damp 
—the  effect  of  an  acid  fluid  the  insect  discharges  to  dissolve  the 
silk.  Thereafter  the  moth  has  no  trouble  pushing  its  way  through 
the  end  of  the  cocoon. 

How  TO  Collect  Butterfues  and  Moths 

Collecting  insects  is  a  wonderful  hobby  for  children.  The 
boy  or  girl  who  is  absorbed  in  this  pastime  derives  ever-increasing 
pleasure  from  collecting.  Often  this  interest  continues  into  adult

hood,  to  be  keenly  enjoyed  for  a  whole  lifetime.  An  outstanding 
example  of  how  the  passion  for  collecting  may  develop,  is  seen 
in  the  case  of  a  Pennsylvania  youngster  who  began  modestly  with 
the  common  monarchs,  swallowtails,  and  cabbage  butterflies  that 
frequented  his  back  yard.  As  the  years  passed,  his  collection  ex- 
panded to  such  proportions  that  eventually  a  museum  bought  it 
for  $20,000! 


THE  POLYPHEMUS,  GIANT  OF  THE  MOTH  WORLD 

The  yellowish  or  brownish  polyphemus  moth  is  one  of  our  largest  moths,  having 
a  wingspread  of  six  inches.  Its  name  (remember  one-eyed  Polyphemus — the  Cyclops 
— and  how  Ulysses  escaped  from  him?)  is  probably  due  to  the  peculiar  eye-like 
spot  it  has  on  each  wing.  At  rest,  it  holds  its  wings  over  its  back. 

How  to  Handle  the  Butterfly  Net:  Butterfly  collecting  is  an  ideal 
hobby  to  enjoy  with  your  children,  sharing  the  excitement  of 
stalking  prey  that  is  elusive  without  being  dangerous.  If  your  child 
starts  collecting  at  an  early  age,  though,  he  is  likely  to  be  too 
impetuous  for  success.  Teach  him  the  value  of  patience  and  care 
at  the  start.  A  slow  and  cautious  approach  to  a  butterfly  is  the 
right  one— despite  the  popular  misconception  that  pictures  collec- 


The  Wonderful  Ways  of  Insects  and  Spiders  [  247 

tors  leaping  with  abandon  and  spasmodically  lashing  out  with 
their  nets. 

Certain  precautions  are  indispensable  to  capturing  your  butter- 
fly, such  as  avoiding  having  the  sun  at  your  back— otherwise  you 
cast  a  shadow,  alarming  the  butterfly.  You  must  coach  your  young- 
ster in  acquiring  the  knack  of  giving  a  quick  sidewise  swoop  with 
the  net;  then,  with  the  butterfly  trapped  inside,  he  must  twist 
his  wrist  sharply  so  that  the  bag  folds  over  the  hoop. 

Usually  this  is  a  good  method  of  attack,  but  some  species  have 
reactions  that  call  for  special  strategy.  For  example:  A  monarch 
trying  to  escape,  flies  straight  up  in  the  air,  whereas  a  royal  fritil- 
lary  drops  down  directly  into  the  grass  and  weeds.  To  snare  either 
of  these  creatures,  you  must  swing  your  net  to  cut  off  escape. 

The  Best  Hunting  Grounds:  Clear,  bright,  windless  days  are  most 
favorable  for  butterfly  hunting.  The  best  hunting  grounds  are 
meadows  dotted  with  milkweed,  thistles  and  orange  butterfly 
weed,  clover  fields,  or  weed-covered  fields  near  a  wooded  tract. 
The  best  time  to  trap  a  butterfly  is  when  it  is  feeding.  Occasionally 
you  will  find  one  so  absorbed  in  sucking  nectar  from  a  flower 
that  you  can  catch  your  prey  between  your  thumb  and  forefinger. 

Baiting  the  Trap  for  Moths:  Night-flying  moths  can  often  be 
secured  as  they  cluster  about  electric  lights.  However,  a  more 
adventurous  way  to  collect  them  is  by  "sugaring"  tree  trunks. 
For  this  you  prepare  bait  in  the  form  of  mashed,  fermented 
peaches  mixed  with  sugar.  (Any  similar  preparation  will  also  do 
the  trick.) 

At  dusk  your  Expedition  for  Moths  takes  a  generous  supply 
of  bait  and  paints  long  streaks  of  it  with  a  stiff  brush  on  the  trunks 
of  several  trees,  making  sure  to  choose  the  sides  sheltered  from 
the  wind.  A  little  after  dark  you  again  visit  the  trees— this  time 
armed  with  flashlight  and  net.  Often  you  will  discover  many 
different  species  enjoying  the  bait. 

Painless  Killing:  On  any  collecting  expedition  you  must  have  a 
"killing  jar"  to  quiet  your  captives  quickly,  painlessly,  and  with- 
out injuring  their  delicate  wings.  You  can  fashion  a  homemade 
container  by  placing  cotton  batting  soaked  with  carbona  in  the 


248  ]  1  he  Wonderful  Ways  of  Insects  and  Spiders 

bottom  of  a  wide-mouthed  pint  jar.  Over  the  cotton,  place  a  piece 
of  wire  screening  to  prevent  the  moisture  of  the  carbona  from 
touching  the  insect.  Keep  the  jar  tightly  covered. 

When  you  remove  the  specimens,  it  is  best  to  use  tweezers  rather 
than  your  fingers;  but  if  tweezers  are  not  available,  pick  up  the 
insects  by  their  legs  or  antennae  and  not  by  their  wings.  Then 
you  may  place  them  temporarily  in  triangular-shaped  holders 
made  of  rather  stiff  paper. 

How  to  Mount  Butterflies  and  Moths:  Mounting  butterflies  and 
moths  for  permanent  exhibit  is  not  too  difficult  for  children  if 
they  have  the  patience  and  are  guided  by  expert  advice.  If  the 
specimens  have  been  kept  for  a  while  and  have  stiffened,  you  must 
soften  them.  You  can  accomplish  this  by  placing  them  in  a  metal 
box  with  a  tight-fitting  cover  and  a  layer  of  wet  sand  on  the 
bottom.  (Add  a  few  drops  of  carbolic  acid  to  the  water  which 
wets  the  sand  to  prevent  any  mold  from  forming.) 

After  twenty-four  hours  in  the  sealed  box,  the  specimens  are 
ready  for  the  setting  board.  This  is  simply  two  pieces  of  soft  wood 
set  side  by  side  with  a  narrow  channel  between  them.  At  the 
bottom  of  the  channel  there  is  a  piece  of  cork  or  balsa  wood. 

Carefully  take  the  softened  butterfly— handling  it  with  tweezers 
is  best;  stick  a  long,  fine  pin  through  its  thorax  and  set  the  body 
in  the  channel  with  the  pin  pushed  down  into  the  cork  or  balsa 
wood.  Spread  the  four  wings  outward  on  the  wooden  sides  until 
the  wings  are  in  a  good  position.  Do  not  put  pins  in  the  wings, 
but  keep  them  from  moving  by  pinning  narrow  strips  of  cloth 
across  them,  placing  the  pins  outside  the  wings. 

The  Storage  Box:  Several  days  on  the  setting  board  are  needed 
before  the  wings  are  thoroughly  dried  out.  Now  they  are  ready 
to  be  stored  in  real  exhibition  fashion.  Storage  boxes  should  be 
shallow  and  may  be  made  of  any  of  several  materials— but  some  are 
decidedly  wrong  for  the  purpose.  In  a  red  cedar  box,  resin  may 
ooze  out  and  make  your  exhibits  greasy.  Cardboard  boxes  absorb 
moisture  from  the  air  and  this  will  cause  the  specimens  to  get 
moldy.  White  pine  is  one  of  the  best  woods. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  249 

When  your  box  is  ready  the  bottom  should  be  lined  with  cork, 
into  which  you  can  stick  your  mounting  pins.  Two  sheets  of 
corrugated  cardboard,  one  placed  on  top  of  the  other  with  the 
corrugations  of  one  running  at  right  angles  to  those  of  the  other, 
may  be  substituted  for  cork.  A  few  flakes  of  the  chemical  dichlor- 
benzol  sprinkled  under  the  cork  will  prevent  tiny  beetles  from 
turning  the  specimens  into  a  fine  brown  dust. 

You  can  then  pin  butterflies  and  moths  in  rows  and  columns^ 
The  ambitious  collector  can  add  a  further  refinement  by  organ- 
izing the  specimens,  putting  insects  of  the  same  family  in  the 
same  box  and  placing  a  male  and  female  of  a  species  side  by  side. 

Many  museums  gladly  furnish  more  detailed  instructions  to 
amateurs,  and  research  in  most  libraries  will  yield  excellent  infor- 
mation about  arranging  and  mounting  specimens.  The  Naturalists' 
Directory  published  by  the  Cassino  Press  of  Salem,  Mass.,  in- 
cludes the  names  of  places  where  equipment  needed  for  insect 
collecting  and  preserving  may  be  purchased. 

Beetles--23,ooo  Species  in  North  America 

Beetles  Get  Around:  Probably  the  easiest  of  all  insects  to  collect 
or  to  become  acquainted  with  in  the  flesh  are  the  beetles.  Not  only 
can  they  be  found  in  innumerable  places  out-of-doors— they  ap- 
pear, unbidden  and  unwelcome,  in  city  apartments. 

Carpet  beetles  sometimes  appear  as  if  by  magic  in  the  wool  of 
rugs  and  upholstery  and  in  stored  cheese  and  cereals.  Equally  tiny 
beetles  turn  up  in  dried  fruits  and  cereal  products.  We  have 
already  seen  that  if  your  family  has  been  collecting  butterflies 
and  you  begin  to  notice  fine  brown  dust  falling  from  your  speci- 
mens, you  can  be  sure  that  beetles  are  working  on  them. 

Differences  and  Resemblances  Among  Beetles:  Once  you  start 
looking  at  beetles  with  some  care,  you  will  appreciate  the  amaz- 
ing degree  of  variation  among  them;  the  result  is  an  enormous 
number  of  species.  Beetles  vary  in  size  from  minute  specimens 
to  some,  found  in  the  tropics,  that  are  larger  than  a  mouse.  There 
are  at  least  twenty- three  thousand  species  on  the  North  American 
continent  alone.  Varied  as  the  members  of  this  insect  tribe  are  in 


250  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

appearance,  nearly  all  the  adults  are  easy  to  identify  by  the  hard, 
veinless  forewings  that  meet  in  a  straight  line  over  the  abdomen. 
In  flight  these  forewings  serve  much  the  same  purpose  as  the 
wings  of  an  airplane,  providing  elevation,  while  the  beetle  is 
actually  propelled  by  the  hind  wings.  The  forewings  also  serve  as 
protective  coverings  for  the  hind  wings,  which  are  folded  beneath 
them.  If  you  could  see  some  of  the  tropical  giants,  you  would  be 
quick  to  notice  their  huge  mandibles,  or  upper  jaws;  but  most  of 
the  smaller  species  also  have  well-developed  mouth  parts,  as  all 
beetles  bite  rather  than  suck. 

The  Firefly— Childhood  Delight:  The  firefly  is  a  member  of  the 
beetle  family.  Children  are  always  intrigued  by  the  way  the  insect 
* 'lights  up"  as  it  flits  through  the  night,  and  they  are  forever 
catching  and  imprisoning  "lightning  bugs"  in  the  hope  of  dis- 
covering their  secret.  In  brief,  this  is  the  explanation:  The  firefly 
produces  a  substance  called  luciferin,  which  glows  when  it  comes 
in  contact  with  air.  Underneath  the  light-producing  area  of  the 
body  there  is  a  reflecting  surface  which  serves  to  strengthen  the 
glow. 

In  some  species  the  females  and  the  larvae  have  no  wings  and 
are  therefore  limited  to  ground  travel.  Both  groups  are  also  light- 
producers— our  common  glowworms. 

Eating  Too  Much  or  Too  Little:  Fireflies  are  valuable  to  man 
because  their  larvae  feed  on  slugs  and  snails,  which  sometimes 
do  damage  to  cultivated  plants.  Mysteriously  enough,  most  of  the 
adults,  as  far  as  we  can  observe,  do  not  eat  at  alll  We  still  have  a 
great  deal  to  learn  about  the  habits  of  this  fascinating  beetle. 

The  Ladybug—Pest  Exterminator:  Another  beetle  dear  to  the 
hearts  of  little  children  is  the  ladybug  or  ladybird  beetle— which 
they  admonish  to  fly  away  home  to  its  burning  house.  These  small, 
hemispherically  shaped  insects  are  also  dear  to  the  hearts  of  fruit- 
growers—but not  for  any  sentimental  reasons.  The  ladybug  preys 
on  great  numbers  of  such  destructive  fruit  pests  as  aphids  and  soft 
scale  citrus  mealy  bugs. 

If  you  happen  to  be  exploring  the  countryside  in  the  fall  you 
may  come  on  a  great  assemblage  of  lady  beetles;  they  congregate 


The  Wonderful  Ways  of  Insects  and  Spiders  [  251 

in  large  numbers  before  going  into  hibernation  under  rocks  and 
forest  litter  and  inside  hollow  trees. 

The  Ground  Beetle^Nighttime  Hunter:  If  you  turn  over  a  stone, 
log,  or  board  lying  on  the  ground— especially  damp  ground— you 
are  likely  to  discover  a  beetle  hideout.  The  ''ground  beetle" 
family  has  many  different  members,  and  most  of  them  remain 
under  cover  during  the  day.  Usually  a  ground  beetle  is  plain 
black  or  brown  and  its  long,  flattened  body  is  carried  rapidly 
over  the  ground  on  its  slender  legs— as  you  will  observe  if  you 
disturb  one;  it  runs  away  as  rapidly  as  possible  when  it  is  dis- 
covered. 

Ground  beetles  feed  mostly  by  night,  looking  for  food  under 
rocks  and  refuse  or  in  the  soil.  Several  species  are  famous  for  their 
caterpillar-hunting;  the  larvae  as  well  as  the  adults  climb  up  tree 
trunks  searching  for  caterpillar  prey. 

Beetles  with  Gas  Bombs:  The  "bombardier"  beetles  are  among 
the  strangest  members  of  the  family.  At  the  first  sign  of  danger 
these  creatures  eject  a  drop  of  liquid  that  quickly  changes  to  a 
tiny  cloud  of  evil-smelling  vapor.  The  source  of  the  liquid  is  a 
gland  at  the  tip  of  the  abdomen,  and  four  or  five  discharges  can 
be  made  before  the  liquid  "bomb"  supply  is  exhausted. 

This  unpleasant  counterattack  will  often  discourage  a  bird  or 
other  aggressor— at  least  long  enough  for  the  beetle  to  scurry  to 
safety.  Many  members  of  the  ground  beetle  family  have  this 
power,  but  one  species  makes  its  discharge  with  a  distinct  "pop." 
This  is  the  true  bombardier.  It  has  a  yellowish  head  and  a  bluish 
body. 

Beetles  Near  Water:  You  may  find  the  tiger  beetle  along  the  shores 
of  streams,  lakes,  or  the  ocean,  and  also  on  woodland  trails.  About 
half  an  inch  long  and  often  brilliantly  colored  with  metallic  greens 
and  purples,  this  handsome  beetle  is  a  prize  for  any  young  col- 
lector; but,  being  a  swift  runner  and  quick  to  take  flight,  it  is 
not  easily  trapped  by  a  novice. 

Sometimes,  as  you  look  down  at  fresh-water  ponds  or  streams, 
you  may  see  black,  oval  whirligig  beetles  cruising  around  tire-

"TIGER"  ANIMALS  HAVE  STRIKING  COLORS 

Animals  named  after  the  tiger,  such  as  the  tiger  salamander,  tiger  swallowtail 
butterfly,  and  tiger  beetle,  are  noted  for  their  brilliant  coloring.  The  tiger  beetle 
at  the  left  is  purple,  the  one  at  the  right  belongs  to  the  six-spotted  species.  It  is 
active  in  the  daytime,  and  found  most  frequently  on  woodland  paths. 


lessly  in  circles— or  dark,  shiny  diving  beetles  that  stay  suspended, 
head  downward,  in  the  water. 

How  to  Collect  Beetles:  If  your  child  is  serious  about  beetle  col- 
lecting, he  can  go  about  it  in  a  number  of  ways.  Flat  rocks  and 
boards  on  moist  earth  have  been  mentioned  as  good  hunting 
grounds.  When  he  finds  beetles  on  a  small  tree  or  bush,  he  can 
hold  an  opened  umbrella  upside  down  under  it  and  then  hit 
the  branches  above,  The  insects  fall  into  the  outspread  trap. 

An  excellent  method  of  snapping  up  beetles  is  to  use  a  small, 
circular  pill  box  in  which  the  cover  fits  over  the  bottom  portion. 
If  you  wish,  you  can  attach  the  two  halves  of  the  box  with  adhesive 
iape  to  the  thumb  and  the  index  or  middle  finger.  It  is  possible  to 


The  Wonderful  Ways  of  Insects  and  Spiders  [  253 

find  some  beetles  on  sandy  shores  by  pulling  up  bunches  of  grass 
and  examining  the  roots;  or  moss  from  stream  banks  may  be 
shaken  over  a  piece  of  paper  for  possible  insect  finds. 

There  are  several  ways  of  setting  traps;  one  method  is  to  set  a 
tin  can  or  narrow  jar  into  the  ground,  the  open  top  flush  with 
the  surface,  and  with  a  bit  of  meat  or  fish  at  the  bottom.  Also, 
after  spring  floods  you  are  likely  to  find  numerous  specimens 
along  streams  and  creeks  where  they  have  been  drowned  and  their 
bodies  left  stranded. 

Carbona  or  ethyl  acetate  is  the  recommended  poison  to  use  in 
a  killing  jar  for  beetles.  Like  butterflies  and  moths  they  can  be 
mounted  for  attractive  exhibition  in  boxes.  The  mounting  pins 
should  go  through  the  right  wing-cover. 

Ants— Colonists,  Workers,  and   Warriors 

Ants,  like  beetles,  are  almost  easier  to  find  than  to  elude. 
You  see  ants  on  lawns,  roadways,  and  city  pavements;  in  gardens, 
forests,  and  pastures.  These  extraordinary  insects  vary  in  size  and 
color  from  the  big  carpenter  ant  to  the  little  brown  species  that 
is  the  most  common  of  all  in  North  America.  There  are  many 
localities  where  you  may  find  this  brown  ant;  but  because  it  has 
been  studied  chiefly  in  cornfields,  it  is  widely  known  as  the 
"cornfield  ant/' 

Ant  Colonies:  The  cornfield  ant,  like  all  members  of  the  ant 
family,  lives  in  colonies.  Each  colony  is  made  up  of  three  prin- 
cipal types  of  ants:  the  queen  (or  fertile  female) ;  the  short-lived 
males  that  die  soon  after  the  mating  flight;  and  the  infertile 
females.  These  last,  the  great  majority,  are  the  ordinary  hard- 
working citizens  of  the  ant  world.  They  are  divided  into  workers, 
soldiers,  or  other  specialized  castes.  The  workers  have  larger  heads 
and  part  of  their  front  legs  is  slightly  thicker  than  in  other  adults 
of  this  species. 

If  you  come  upon  a  mound  of  earth  about  which  ants  are 
hustling,  your  youngster  may  exclaim,  "There's  an  anthill!"  And 
if  he  is  of  an  adventurous  turn  of  mind,  he  may  want  to  dig  into 
it  to  see  just  what  an  ant  colony  is  like.  But  in  order  to  examine 


254  ]  7*^^  Wonderful  Ways  of  Insects  and  Spiders 

a  nest  successfully,  you  have  to  dig  down  with  great  skill— else 
you  may  merely  ruin  it. 

Inside  the  Ant  Colony:  Observe  the  nests  of  cornfield  ants  closely 
and  you  will  realize  that  these  nests  vary  greatly  in  size.  The 
mound  of  a  long-established  colony  covers  a  much  larger  area 
than  that  of  a  new  one.  As  a  rule,  the  underground  rooms  are 
only  a  few  inches  below  the  surface.  But  after  a  long  dry  spell, 
or  if  the  nest  is  located  in  sandy  soil,  the  rooms  are  deeper  in  the 
earth;  for  soil  that  is  very  dry  becomes  too  crumbly  for  excavation. 
In  the  winter  you  would  find  the  apartments  occupied  only  by 
inactive  adults  and  larvae.  In  midsummer  the  rooms  bulge  with 
eggs,  larvae,  pupae,  workers,  males  and  females.  (The  eggs  are 
tiny  specks.)  The  larvae  are  white  maggot-like  creatures,  and  the 
pupae  are  enclosed  in  whitish  cocoons  about  an  eighth  of  an  inch 
long.  Often  mistakenly  called  "ant  eggs,"  the  pupae  are  collected 
in  large  numbers  and  sold  as  fish  and  bird  food. 

How  Ant  Life  is  Organized:  If  you  were  to  discover  an  ant  nest 
on  a  fine  afternoon  in  August  or  early  September,  you  might 
find  the  occupants  swarming  excitedly  about  the  entrance;  you 
might  also  notice  that  many  of  them  have  wings.  Every  few 
minutes  a  winged  form  takes  to  the  air.  Some  of  these  are  males, 
some  females.    (Apparently  their  mating  takes  place  in  the  air.) 

When  the  female  returns  to  the  ground  she  breaks  off  her  wings, 
then  burrows  a  few  inches  into  the  earth  or  finds  an  opening 
beneath  a  log  or  stone.  Here  she  forms  a  small  cell.  She  may  then 
immediately  start  to  lay  her  eggs— or  she  may  wait  until  the  follow- 
ing spring.  As  time  goes  on  she  eats  some  of  the  eggs— they  are  the 
only  food  she  has— and  continues  to  lay  more.  About  two  months 
after  she  begins  to  raise  her  young  she  may  have  one  or  two 
workers. 

During  the  first  year,  if  she  does  well,  her  colony  increases  to 
about  twenty-five  adult  workers.  Their  duty  is  to  search  far  and 
wide  for  her  food.  They  feed  her  and  the  larvae  as  well,  also 
helping  the  larvae  to  spin  their  cocoons  and  in  time  assisting  the 
new  adults  as  they  escape  from  these  cocoons.  Their  mandibles 
and  forelegs  make  excellent  tools.  With  these,  too,  they  dig  out 


The  Wonderful  Ways  of  Insects  and  Spiders  [  255 

new  tunnels  and  rooms;  and  as  they  dig  and  bring  soil  up  to  the 
surface  of  the  ground,  the  "anthill"  grows  larger.  When  the  soil 
becomes  cold,  they  close  the  entrance  to  the  nest  and  rest  quietly 
in  the  rooms  until  the  next  spring. 

Savage  Ant  Warriors:  Not  all  ants  are  as  settled  in  their  ways  as 
the  cornfield  ant.  There  are  some  that  do  not  bother  to  build 
homes  at  all:  They  are  almost  constantly  on  the  move,  wandering 
from  place  to  place  in  search  of  food.  Among  these  nomads  are 
the  "driver"  ants  of  Africa  and  tropical  America.  They  march  in 
close  formation,  in  columns  an  inch  or  two  wide  and  sometimes  a 
mile  long!  Even  animals  as  large  as  a  deer  will  flee  in  terror  from 
such  an  army. 

Many  species  of  ants  are  savage  fighters.  Sometimes  battles  are 
fought  by  two  colonies  of  the  same  species  but  more  often  there 
is  a  struggle  of  one  species  against  another.  The  fighting  may 
occur  between  two  large  groups  or  even  between  individuals. 

If  you  stop  to  watch  a  lively  group  of  ants  on  the  ground  or 
sidewalk,  you  may  find  it  is  divided  into  two  factions  struggling 
over  a  bit  of  food— or  you  may  not  even  discover  the  cause  of  the 
conflict.  I  have  heard  of  a  sidewalk  ant  battle  that  raged  for  more 
than  five  hours,  until  each  colony  was  reduced  to  a  few  battered 
members. 

You  may  wonder  how  the  ants  in  such  a  struggle  know  friend 
from  foe.  Members  of  different  colonies  look  exactly  alike,  yet 
you  see  individuals  meet  and  at  once  pass  on  to  another  warrior 
or  start  fighting.  Apparently  an  ant's  antennae  help  it  distinguish 
its  own  team  mates  from  the  opposition— for  as  two  fighters  meet, 
the  antennae  of  each  touch  the  head  of  the  other.  There  is  also  a 
theory  that  ants  have  a  characteristic  odor  that  varies  with  each 
colony  and  may  thus  be  an  aid  to  solving  the  "friend-or-foe" 
puzzle. 

Ant  Hangers-on:  As  you  observe  some  ant  colonies  you  may  be 
puzzled  by  the  presence  of  other  insects  that  act  as  though  they 
belong  there.  If  you  were  able  to  study  ant  nests  all  over  the 
ivorld,  you  would  find  there  are  actually  several  thousand  differ- 
-ent  kinds  of  insects  that  make  their  home  with  ants.  Some  of 


256  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

these— certain  kinds  of  beetles,  for  example— the  ants  use  to  obtain 
savory  secretions.  Others  are  hangers-on,  scavengers,  thieves,  or 
enemies.  Some  of  them  to  all  outward  appearances  are  ants. 

Among  the  best  known  are  aphids— tiny  insects  that  feed  on 
the  juices  of  plants  and  give  off  from  their  bodies  droplets  of 
honeydew.  Some  aphids  are  popularly  known  as  "ant  cows."  The 
ants  protect  them  and  even  carry  them  from  one  food  plant  to 
another,  "milking"  them  by  stroking  their  back  with  their  anten- 
nae. The  milk  is  the  sweet,  colorless  fluid  that  we  call  "honeydew." 

Observing  Ants  Indoors 

A  child  can  get  a  great  deal  of  pleasure  by  watching  ants, 
and  he  can  learn  a  great  deal  about  their  habits,  if  you  keep  some 
in  your  home— provided  the  ants  are  there  through  your  choice 
and  not  their  own,  and  you  supply  suitable  living  quarters  for 
them.  One  type  of  house  that  is  easy  to  make  might  be  described 
as  a  glass  sandwich. 

Use  two  pieces  of  window  glass  about  ten  or  twelve  inches 
square.  One  will  serve  as  the  base,  the  other  as  the  top.  Around 
the  edges  of  the  base,  glue  quarter-inch  strips  of  wood  that  fit 
snugly  at  the  corners.  Leave  two  openings  in  one  strip  that  you 
will  use  later— one  for  food,  the  other  for  water.  Inside  the  water 
opening  you  keep  a  sponge  that  can  be  kept  moist  with  a  medicine 
dropper.  When  you  are  not  feeding  the  tenants,  you  can  keep 
these  two  openings  plugged  with  cotton. 

How  to  Collect  Ants:  You  are  now  ready  to  collect  your  ants. 
Dig  around  a  nest  carefully  with  a  small  shovel  or  trowel,  lift  the 
dirt  with  the  insects  into  a  carton  and  close  it  tightly  to  carry 
home.  Transfer  both  dirt  and  insects  to  the  glass  that  you  have 
rimmed  with  strips.  At  this  point  you  need  to  work  quickly  to 
glue  the  other  square  of  glass  to  this  base  and  finally  seal  all 
edges  with  adhesive  tape. 

Place  a  piece  of  cardboard  of  equal  size  on  top— ants  need  dark- 
ness most  of  the  time.  You  can  use  two  strips  of  adhesive  as  hinges 
to  attach  this  cover  to  one  side,  lifting  the  cardboard  whenever 
you  wish  to  watch  your  insects  at  work. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  257 

You  may  see  them  constructing  a  central  hall,  excavating  a 
system  of  tunnels,  cleaning  themselves  with  tongue  and  front 
legs— they  do  this  repeatedly— and  sometimes  lying  down  to  sleep, 
their  legs  pulled  close  to  the  body.  It  is  important  to  have  a  queen 
in  your  colony— otherwise  the  activities  of  the  captives  will  show  a 
far  from  complete  story  of  life  in  an  anthill. 

How  to  Take  Care  of  Captive  Ants:  The  care  of  ants  is  rather 
simple.  The  soil  should  be  kept  moist  by  inserting  water  through 
the  opening  at  least  once  a  week;  the  insects'  home  should  not  be 
left  in  bright  sunlight  or  near  a  radiator.  A  drawer  or  closet  is  a 
good  place  to  keep  them  when  you  are  not  watching  them.  A 
drop  of  honey  should  be  supplied  every  few  days,  as  well  as  a  little 
solid  food,  such  as  tiny  morsels  of  mashed  walnuts,  apples,  bananas, 
and  bits  of  dead  insects. 

Grasshoppers  and  Their  Music 

Katydids— Fiddlers,  Not  Singers:  Katydids  have  become  so  closely 
identified  with  this  name  because  of  their  insistent  refrain  Katy 
did,  no  she  didn't,  that  people  sometimes  forget  these  insects  are 
also  grasshoppers.  The  grasshoppers  are  divided  into  two  groups: 
the  short-  and  long-horned  families.  The  "horns"  (really  the 
antennae)  are  considered  long  if  they  are  nearly  as  long  as,  or 
longer  than,  the  insect's  body.  Katydids  belong  to  the  long-horned 
group. 

A  child  hearing  them  on  a  summer  night  may  refer  to  their 
"singing,"  but  "fiddling"  is  a  better  word  for  their  kind  of  music. 
A  male  katydid— the  females  only  listen— rubs  its  left  wing  over 
the  right  wing.  The  left  wing  has  a  file-like  row  of  ridges,  while 
the  right  wing  has  a  hard  little  scraper  just  behind  the  shoulder 
where  the  wings  overlap;  the  rubbing  of  the  wings  produces  the 
fiddling  sound. 

Fiddlers  All:  It  is  the  broad-winged  or  leaf-winged  katydid  that 
plays  its  name  with  insistent  repetition.  The  large  oblong-winged 
tree  katydid  has  a  refrain  of  Zzzzzz-Ipswich;  the  fork-tailed  bush 
katydid  plays  a  slow  zeep-zeep-zeep  now  and  then;  and  the  com- 
mon meadow  katydid  fiddles  several  soft  zees  in  a  row,  each  faster 
than  the  one  before,  and  then  hits  and  holds  a  high  zeee.

The  Wonderful  Ways  of  Insects  and  Spiders 


"KATf  DID  —  NO  SHE  DIDNT" 

Yhe  katydids  are  long-horned  grasshoppers  noted  for  their  fondness  for  fiddling. 
The  sound  is  produced  by  rubbing  the  left  wing  over  the  right  wing.  The  males 
do  all  the  playing,  while  the  females  are  apparently  content  to  listen.  The  katydid 
has  hearing  organs  on  its  front  legs. 

A  short-horned  grasshopper  has  a  different  fiddling  technique. 
Its  long  hind  leg  forms  the  bow,  and  a  coarse  outer  wing  the 
fiddle.  It  may  play  one  leg  and  wing  at  a  time  or  both  sides 
together— a  "one-man  duet."  However,  little  actual  music  is 
created  by  these  efforts;  you  can  hear  the  resulting  rasps  for  only 
a  few  feet. 

Both  males  and  females  have  large  hearing  organs.  You  can  see 
what  looks  like  an  oval  window  on  each  side  of  the  first  abdominal 
segment  under  the  wings.  What  you  see  is  the  outer  part  of  the 
grasshopper's  "ears." 

Grasshoppers  blend  so  successfully  with  their  surroundings 
that  it  is  not  easy  to  spot  them  during  the  day  except  when  they 
take  wing.  Some  of  the  smaller  katydids  are  easily  startled  into 
flight  from  tall  weeds  and  grasses  where  they  spend  much  of 
their  time.  In  the  country  you  can  have  a  lively  evening  tracking 
down  the  little  insect  fiddlers;  take  a  flashlight  along  and  let 
yourself  be  guided  by  their  sounds. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  259 

Crickets  Join  the  Insect  Serenade:  The  chirpy,  cheerful  cricket 
produces  music  with  its  wings  in  the  same  way  as  the  katydid, 
but  usually  with  its  right  wing  over  the  left— whereas  the  katydid, 
as  we  have  seen,  rubs  its  left  wing  over  the  right.  To  a  listening 
youngster  it  may  seem  that  the  katydids  dominate  the  insect 
serenade;  but  crickets  contribute  their  share  of  the  melodious 
performance.  The  tune  of  the  common  snowy  tree  cricket  begins 
as  a  musical  waa-waa-waa,  played  by  individuals,  each  "on-  his 
own."  But  soon  they  join  forces  and  play  as  if  they  were  following 
a  conductor's  baton. 

Crickets  As  Weather  Forecasters:  The  performance  of  the  snowy 
tree  cricket  is  directly  related  to  the  temperature.  By  counting 
the  number  of  notes  it  produces  each  minute,  you  can  roughly 
gauge  what  your  thermometer  registers.  Thus,  a  hundred  chirps 
to  the  minute  indicate  a  temperature  of  63  degrees.  Increasing  its 
tempo  as  the  temperature  rises,  this  cricket  slows  down  when  it 
gets  cooler. 

The  common  black  crickets,  with  their  clear  chirp,  are  the  first 
musicians  you  will  hear  in  summer.  You  may  often  discover  them, 
by  late  August,  if  you  turn  over  an  old  board  or  stone.  They 
run  fast  but  despite  their  muscular-looking  legs  they  do  not 
imitate  the  grasshopper's  high-jumping  tactics. 

Cricket  on  the  Hearth:  The  cricket  that  may  serenade  you  from 
indoors  after  cool  weather  begins  is  not  necessarily  the  same  kind 
about  which  Dickens  wrote  so  appealingly  in  England;  but  the 
American  field  cricket  is  also  a  cheery  visitor  to  have  on  the 
hearth.  The  European  cricket  is  now  quite  well  established  in 
the  eastern  United  States  and  is  a  persistent  fiddler.  Unfortunately, 
once  these  musicians  are  indoors  they  do  not  limit  their  activities 
to  music  but  may  get  into  food  and  eat  holes  in  everything  made 
of  cloth. 

Hoxv  To  Keep  Cricket  Pets:  In  the  natural  state,  not  many  crickets 
survive  the  coming  of  frost.  However,  if  they  are  adopted  as  pets, 
they  will  often  live  through  the  winter  with  every  appearance  of 
enjoying  themselves.  You  can  make  a  cage  for  a  cricket  very 
simply  with  a  flowerpot  full  of  earth  and  a  kerosene  lamp  chimney. 


26o  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

Sink  the  chimney  into  the  earth  to  a  depth  of  two  inches  and 
cover  the  top  with  a  piece  of  mosquito  netting  held  in  place  by 
a  rubber  band.  You  can  make  a  similar  cage  with  a  large  jar,  or 
an  aquarium  also  covered  with  mosquito  netting,  and  with  soil 
and  plants  set  on  the  bottom. 

Once  you  have  obtained  a  few  crickets,  place  them  inside  the 
cage  with  a  cabbage  leaf  or  other  greens  and  fasten  the  mosquito 
netting  top.  Aside  from  providing  their  leafy  food,  it  is  a  good 
idea  to  occasionally  drop  a  little  corn  meal  saturated  with  water 
into  the  glass  cage— it  will  furnish  moisture  as  well  as  food. 
Periodically,  too,  the  inside  quarters  should  be  sprinkled  with 
water  to  keep  the  atmosphere  moist. 

You  may  conclude  from  sad  experience  that  it  is  not  practicable 
to  keep  more  than  one  cricket  in  the  cage;  they  frequently  start 
fighting  with  fatal  results. 

Bees— Honey-Makers,  Pollinizers,  and  Stingers 

What  probably  impresses  children  above  all  about  bees 
is  their  stinging  ability.  "Is  it  true  that  a  bee  dies  after  it  stings 
you?  Can  only  females  sting?  Don't  bees  sting  when  they  are 
swarming?"  I  have  heard  youngsters  put  these  queries  incessantly 
before  the  topic  of  honey-making  ever  came  up. 

The  Bee's  Sting:  Tormenting  humans  is  far  from  the  primary  use 
of  stingers.  When  the  first  queen  hatches  in  a  hive,  she  imme- 
diately rips  open  other  queen  cells— unless  she  is  restrained  by 
the  workers— and  stings  the  inmates  to  death,  thereby  removing 
all  possible  rivals.  Queens  have  the  ability  to  sting  over  and 
over  again— but  they  use  their  sting  only  on  other  queens. 

It  is  a  worker  bee  that  will  sting  you,  and  it  commits  suicide 
by  doing  so.  Stinging  brings  twenty- two  muscles  into  play;  when 
the  stinger  is  torn  out  of  the  worker's  body,  death  results. 

The  order  of  insects  to  which  bees— and  wasps  and  ants— belong 
is  the  only  one  in  which  genuine  stingers  are  found.  The  stinger 
is  the  modified  ovipositor  (or  egg-laying  organ)  of  the  female 
worker,  so  obviously  the  males  or  "drones"  possess  no  stings.  In 
early  summer,  when  a  mass  of  bees  leave  their  hive  with  a  queen 


The  Wonderful  Ways  of  Insects  and  Spiders  [  261 

to  found  a  new  home,  they  seem  especially  tolerant  of  bystanders 
and  almost  never  sting  during  this  swarming. 

Very  Few  Kinds  of  Bees  Store  Honey:  Many  children  and  even 
some  grownups  have  a  mistaken  idea  that  all  bees  store  honey. 
Actually  this  is  true  of  only  a  few  of  the  thousands  of  kinds  of 
bees  known  to  exist.  Most  of  them  eat  nectar  as  they  take  it  from 
the  flowers,  instead  of  using  it  for  honey. 

The  true  honeybees,  so  valuable  in  fertilizing  such  plants  as 
clover  and  fruit  trees,  are  native  to  Europe;  they  were  introduced 
to  North  America  by  colonists  in  the  seventeenth  century.  If  you 
find  any  of  these  in  hollow  trees  in  the  woods,  they  are  swarms 
that  have  escaped  from  man-made  hives— or  descendants  of  such 
bees. 

The  Underground  Bumblebee:  The  large,  hairy  bumblebee,  with 
its  black  coat  marked  with  yellow,  orange,  or  red,  is  probably 
more  quickly  recognized  by  children  than  most  species.  This 
honey  manufacturer  is  native  to  America.  Bumblebees  live  in 
large  colonies  underground,  where  they  construct  many-celled 
combs.  In  the  cells  they  lay  eggs,  store  pollen  and  nectar,  and 
make  honey. 

Playing  Bee  Detective:  Country  youngsters  have  long  delighted  in 
tracking  down  honeybees  that  have  ''gone  native,"  and  finding 
their  store  of  honey.  The  bee  detective's  equipment  is  a  small  box 
with  either  honey  or  sugar  water  and  an  opening  large  enough  to 
enable  the  bees  to  get  to  it.  The  same  purpose  is  achieved  by 
using  one  of  those  frames  in  which  honey  is  bought  in  the  comb. 
Putting  some  flour  or  cornstarch  in  the  receptacle  will  give  the 
bees  a  touch  of  white  as  they  take  the  bait.  Thus  they  will  be 
more  conspicuous  at  a  distance,  making  it  possible  to  follow  the 
direction  of  their  flight. 

Your  bee  detective  places  the  box  on  a  stump  or  post  in  a 
neighborhood  where  bees  are  working.  By  moving  the  box  at 
intervals  in  the  direction  of  their  flight,  the  youthful  hunter 
gradually  narrows  down  the  distance  to  the  bees'  storehouse. 

The  first  customers  will  usually  bring  other  workers  with  them. 
Individual  bees  can  be  identified  after  a  while,  and  the  lessening 


262  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

time  required  to  complete  the  round  trip  will  indicate  how  much 
the  distance  to  the  hive  is  decreasing.  Although  the  youngster  will 
be  overjoyed  when  he  finally  locates  the  store  of  honey,  it  is  a 
wise  precaution  to  have  him  call  on  adult  help  in  removing  the 
honey  from  the  hollow-tree  storehouse. 

How  Bees  Use  "Glue":  When  you  see  a  bee  purposefully  visiting 
tree  after  tree,  it  may  be  gathering  water  from  the  buds.  The  other 
object  of  its  quest  may  be  a  brown  resinous  material— called 
"propolis"  or  "bee  glue"— that  these  insects  use  for  smoothing 
rough  places  in  the  hive.  This  assignment  is  given  to  young  bees 
on  their  first  flights. 

Pollination  by  Messenger  Service:  Later  on,  the  bees  set  about 
collecting  pollen  and  finally  nectar.  They  knead  the  pollen  into 
a  little  ball  and  tuck  it  into  a  cavity  on  the  hind  leg;  they  obtain 
nectar  by  extending  their  tongue  into  a  flower  and  sucking  the 
fluid.  There  are  some  species  of  clovers  and  other  plants  with 
long-tubed  corollas  that  depend  completely  on  bumblebees  and 
other  long-tongued  species  of  bees  for  pollination. 

Western  fruitgrowers  keep  colonies  of  bees  in  the  great  orch- 
ards for  fertilizing  the  fruit-tree  blooms.  (Some  owners  rent  the 
bees  for  this  purpose.)  Honeybees  are  more  valuable  to  man  in 
this  way  than  they  are  as  producers  of  honey  and  beeswax. 

What  Goes  On  In  A  Beehive:  Many  children  are  familiar  with 
the  beehives  provided  by  people  to  keep  bee  colonies  and  to  take 
advantage  of  the  bees'  honey  production.  This  kind  of  hive 
usually  has  one  lower  story,  in  which  the  frames  are  used  both 
for  the  brood  and  for  storing  honey  which  the  bees  use  in  winter. 
There  are  one  or  more  upper  stories  with  additional  frames  for 
storing  honey. 

As  they  would  do  in  a  natural  hive,  the  bees  house  their  brood 
in  the  lower  section,  then  work  hard  filling  the  top  part  with 
honey.  Beekeepers  remove  the  upper  frames  as  they  are  filled. 
Small  sections  of  each  frame,  containing  about  a  pound  of  honey, 
are  taken  out  in  the  form  you  buy  them  in  at  the  store.  The 
honey  is  removed  from  the  larger  frames  and  sold  in  liquid  form. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  263 

How  Bees  Make  Honeycombs:  To  store  honey,  honeybees  man- 
ufacture cells  from  wax  produced  by  certain  glands  in  their 
bodies.  (Bumblebees  do  this  also.  Many  species  make  their  cells 
of  wood,  leaves,  or  earth.) 

The  making  of  a  honeybee  comb  is  an  amazing  example  of 
co-operative  effort.  A  group  of  bees  begin  by  forming  a  living 
curtain  of  their  bodies,  each  one  holding  on  with  its  forefeet 
to  the  hind  feet  of  the  bee  above.  After  they  have  remained  in 
that  position  for  some  time,  little  plates  of  wax  appear  on  each 
insect's  abdomen.  They  then  chew  the  wax  and  form  it  into  a 
comb. 

The  Bee's  "Honey  Stomach":  The  nectar  that  the  bees  take  from 
flowers  becomes  honey  in  the  insects'  "honey  stomach."  This 
organ  is  not  involved  in  ordinary  digestion;  the  nectar  is  mixed 
in  the  honey  stomach  with  secretions  from  glands  that  cause 
chemical  changes.  The  cane  sugar  of  nectar,  for  example,  turns 
into  the  fruit  sugar  of  honey— a  form  that  we  can  digest  more 
readily. 

Money  From  Honey:  Keeping  honeybees  is  a  hobby  that  may 
be  made  to  pay  dividends.  Some  people  are  successful  at  housing 
them  in  relatively  small  back  yards,  so  long  as  there  are  nearby 
meadows  to  which  the  insects  can  fly.  Bees  need  comparatively 
little  care,  but  before  you  purchase  a  swarm  or  hive,  you  will 
do  well  to  seek  advice  either  directly  from  an  expert  or  from 
literature  on  the  subject. 

Some  Unpopular  Insects 

Wasps— Clever  Papermakers 

Proud  indeed  is  the  young  nature  collector  who  can  add 
a  hornet's  nest  to  his  home  exhibits.  It  is  a  real  showpiece— an 
impressive  example  of  the  skill  of  the  insects  often  claimed  to  be 
the  cleverest  of  the  entire  six-footed  tribe. 

The  bald-faced  hornet  is  one  of  several  wasps  that  manufacture 
paper  by  chewing  bits  of  wood  to  a  pulp  and  use  it  to  construct 
nests  sometimes  massive  in  size.  Some  wasps— like  the  hornet- 
suspend  the  nest  from  a  branch  of  a  tree  or  bush,  while  others 


264] 


The  Wonderful  Ways  of  Insects  and  Spiders 


attach  their  homes  to  eaves  or  barn  roofs— or  locate  them  in 
cavities  in  the  ground  or  in  tree  trunks. 

How  the  Wasp  Builds  Its  Paper  Nest:  If  you  observe  these  wasps 
when  they  are  busy  with  their  home  construction,  you  will  see 
them  flying  off  in  search  of  weathered  wood  or  cut  wood  fibers 
in  a  post,  an  unpainted  old  building,  or  a  piece  of  a  dead  tree 
trunk.  From  something  of  this  sort,  a  wasp  builder  bites  and 
tears  the  fiber  with  its  mandibles,  taking  enough  to  form  a  pellet 
about  an  eighth  of  an  inch  across  the  middle.  It  tucks  the  pellet 
under  its  chin  and  chews  until  the  wood  is  sufficiently  turned  into 
a  mass  of  doughy  pulp. 


STYLES  IN  WASP  ARCHITECTURE 

When  wasps  are  mentioned,  most  of  us  immediately  think  of  their  stinging  habits. 
Actually,  their  abilities  as  builders  are  far  more  remarkable.  The  ''paper"  wasp 
(upper  left)  chews  wood  into  paper  pulp  for  its  nest.  The  mud-dauber  wasps 
(right)  mix  mud  and  saliva  to  mortar  their  nests. 


The  insect  now  returns  to  the  nest  and,  alighting  astride  an 
unfinished  layer  of  paper,  presses  down  the  new  ball  of  pulp, 
biting  it  to  fasten  it  in  place.  Then  the  wasp  walks  slowly  back- 


The  Wonder  Jul  Ways  of  Insects  and  Spiders  [  265 

ward,  unraveling  the  ball  and  fastening  it  to  the  layer  of  paper 
below.  When  the  new  pulp  is  all  laid  out,  the  wasp  runs  forward, 
then  once  more  backs  up,  biting  the  pulp  all  along  the  way  to 
flatten  it.  While  the  moisture  is  drying  out,  the  wasp  is  off  collecb 
ing  more  fiber.  As  these  fibers  are  collected  from  a  variety  of 
sources,  the  color  of  the  paper  may  vary  in  different  parts  of 
the  nest! 

It  is  usually  safe  to  watch  bald-faced  hornets  or  yellow  jackets 
—which  are  also  papermakers— at  work  as  long  as  you  do  not 
disturb  them.  But  if  you  poke  into  their  nest  or  meddle  with 
their  activities,  you  will  quickly  discover  the  origin  of  the  phrase, 
"mad  as  a  hornet." 

Wasp  Homes  of  Mud:  Paper  nests  are  not  the  only  kind  built  by 
wasps.  Your  observant  youngster  may  come  across  cartridge-shaped 
cells  made  of  mud  and  attached  to  the  walls  of  garages,  barns,  or 
other  buildings— as  well  as  many  out-of-the-way  "unlikely"  places. 
Such  cells  are  constructed  by  mud-dauber  wasps. 

At  first  there  is  only  one  cell,  about  an  inch  long;  but  soon  an- 
other is  added  next  to  it,  and  before  the  builder  is  finished  there 
may  be  half  a  dozen  more.  On  a  hot  summer  day  you  may  catch 
sight  of  these  wasps  collecting  little  balls  of  mud  at  the  side  of 
a  puddle  of  water.  You  can  even  set  up  an  observation  post  by 
forming  a  mud  puddle  there. 

The  Wood-Eating  Termites 

Most  children  know  about  these  notorious  insects,  and 
the  damage  they  do  to  wooden  structures;  but  few  people  get  to 
see  these  creatures.  Termites  live  in  the  dark  seclusion  of  tunnels, 
and  the  first  intimation  of  their  presence  may  come  when  a  fence 
falls  down  or  a  wooden  step  gives  way.  (They  have  also  been 
known  to  eat  through  table  tops  and  window  frames!) 

The  one  time  you  are  likely  to  see  them  in  the  light  of  day 
is  on  the  occasion  of  the  marriage  flight  of  a  colony.  Then  swarms 
of  these  insects— the  male  and  female  winged  forms— may  emerge 
from  walls,  porch  supports,  or  anywhere  near  the  wood  founda-

Though  termites  are  often  called  "white  ants,"  they  belong  to 
an  entirely  different  order  of  insects.  It  is  easy  to  recognize  them 
by  their  shape;  termites  are  broad  where  the  thorax  and  abdomen 
join.  They  do  not  have  the  indentation  or  * 'waist"  that  all  ants 
have.  The  worker  and  soldier  termites  are  almost  colorless  and 
blind.  The  winged  females  and  males,  the  future  queens  and 
kings  of  new  colonies,  are  dark-colored  and  have  eyes.  Actually 
termites  are  more  closely  related  to  roaches  than  to  ants. 

How  Termites  Digest  Wood:  Nearly  any  child  can  tell  you  that 
termites  "eat  wood,"  but  few  of  us  are  aware  of  the  strange  alli- 
ance that  makes  it  possible  for  them  to  live  on  this  "food."  Each 
termite  harbors  numerous  tiny  one-celled  animals  that  break 
down  the  cellulose  content  of  wood  into  digestible  substances. 
If  you  were  to  place  a  termite  in  a  temperature  high  enough  to 
kill  its  minute  parasites,  it  might  continue  to  eat  wood  but  would 
derive  no  nourishment;  before  long  it  would  die  of  starvation! 

Flies— Carriers  of  Disease 

We  all  dislike  and  mistrust  flies.  They  are  generally  targets 
for  destruction  rather  than  objects  of  study.  But  despite  all  our 
efforts  to  wipe  them  out,  they  are  so  extraordinarily  successful 
in  surviving  that  they  become  objects  of  interest  for  that  very 
reason.  There  are  many  species  of  flies,  but  probably  the  most 
familiar— perhaps  the  most  familiar  of  all  insects— is  the  common 
housefly. 

A  Generation  A  Month:  The  difficulty  of  keeping  houseflies  in 
check  is  easy  to  understand  once  we  are  aware  of  the  rate  at 
which  they  produce  their  young.  The  female  lays  a  mass  of  from 
twenty-five  to  about  a  hundred  eggs  at  a  time.  In  less  than  a  day 
these  hatch  into  tiny  white  maggots  about  as  large  as  the  point 
of  a  pin.  The  maggots— actually  larvae— mature  in  four  or  five 
days,  then  enter  the  pupa  stage  which  lasts  another  five  days  or 
so.  The  full-grown  fly  now  appears. 

Shortly  after,  the  mother  of  this  brood  may  lay  another  mass 
of  eggs;  and  the  new  generation  begins  producing  young  of 
its  own  within  a  few  days  after  becoming  adults.  As  long  as  warm 


The  Wonderful  Ways  of  Insects  and  Spiders  [  267 

weather  lasts,  generations  follow  each  other  from  within  two 
weeks  to  a  month. 

The  arrival  of  cold  weather  destroys  the  adult  flies,  eggs,  and 
larvae.  The  pupae  in  their  protective  shells  survive,  remaining 
inactive  during  the  winter.  With  the  onset  of  warm  weather  they 
quickly  complete  their  development,  and  the  same  process  begins 
all  over  again.  The  average  life  of  an  adult  is  from  two  to  three 
weeks;  some  live  considerably  longer. 

The  Fly's  Cleaning  Routine:  If  you  have  ever  watched  a  fly  clean- 
ing itself,  you  must  have  wondered  at  its  reputation  for  filthiness. 
Its  grooming  is  remarkably  thorough.  First  it  rubs  its  front  feet 
together  briskly  so  that  the  hairs  on  one  leg  act  as  a  brush  for  the 
other  leg;  then  the  fly  nibbles  at  the  front  feet  with  the  rasping 
disk  it  has  in  lieu  of  teeth. 

Next  the  creature  gives  its  whole  head  an  energetic  scrubbing 
with  its  clean  front  feet.  It  pulls  forward  its  middle  pair  of  legs, 
one  at  a  time,  and  brushes  and  nibbles  them.  Finally  its  hind  feet 
are  used  to  clean  each  other  and  to  brush  its  wings  and  most  of 
its  body. 

All  this  careful  grooming  is  deceptive,  however,  as  far  as  pro- 
tecting our  health  is  concerned.  Flies  breed  in  manure  and  the 
odors  of  fermented  or  decayed  plants  and  animals  have  a  special 
attraction  for  them.  Harmful  germs  cling  to  their  feet  and  are 
deposited  in  food  on  which  they  may  alight.  Typhoid  fever  and 
amebic  dysentery  are  among  the  many  diseases  they  are  known  to 
spread.  It  is  true  that  many  kinds  of  flies  render  important  service 
as  scavengers  and  exterminators  of  other  objectionable  insects; 
but  credit  is  given  them  grudgingly, if  it  is  given  at  all,  because 
their  relatives  are  so  unpopular.  \ 

The  Fly's  Wing  Structure:  Flies  differ  from  most  other  adult 
insects  in  having  a  single  pair  of  wings^instead  of  two  pairs. 
(Dragonflies,  mayflies  and  others  with  four  wings  are  not  really 
flies.)  Nevertheless  they  seem  able  to  keep  flying  indefinitely,  as 
you  will  notice  when  you  chase  one  with  a  swatter.  Hind  wings 
are  replaced  by  short  stalks,  or  knobs,  which  are  important  in 
balancing  them  as  they  fly. 


268  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

How  Flies  Walk  Upside  Down:  You  can  observe,  too,  how  a  fly 
crawls  up  walls,  windows,  and  across  a  ceiling  as  easily  as  it  walks 
across  the  floor.  Two  tiny  claws  on  the  last  segment  of  each  foot 
aid  it  in  walking  on  rough  surfaces.  It  also  has  on  each  foot  two 
small  flat  pads  covered  on  the  lower  side  with  tiny  hairs.  These 
hairs  give  out  a  sticky  fluid  which  effectively  holds  the  insect  on 
slippery  surfaces  and  upside-down  positions.  It  is  these  hairs 
that  retain  the  great  number  of  germs  carried  by  flies. 

Bloodthirsty  Mosquitoes 

As  in  the  case  of  the  bee's  sting,  the  feature  of  the  mosquito 
that  chiefly  interests  children  is  this  insect's  bite.  But  while  many 
bees  are  highly  useful  to  man,  little  but  trouble  can  be  expected 
from  mosquitoes.  In  the  humid  tropics  they  are  the  dreaded 
carriers  of  such  diseases  as  malaria  and  yellow  fever.  The  relatively 
harmless  and  very  abundant  salt-marsh  mosquitoes  of  the  Atlantic 
and  Gulf  coasts  inflict  painful  bites  but  do  not  transmit  disease. 
The  female  mosquitoes,  like  the  female  bees,  are  the  trouble- 
makers; the  female  of  most  species  has  piercing-sucking  mouth 
parts  and  its  thirst  for  blood  makes  it  a  great  pest  for  man  and 
beast.  Some  males  have  an  elongated  "beak,"  but  it  is  not  suited 
for  piercing  skin.  They  live  on  the  juices  of  fruits  and  plants. 
It  is  the  females,  too,  that  "sing"  by  vibrating  thin  hard  projec- 
tions that  lie  across  their  breathing  pores. 

How  Mosquito  Eggs  Develop:  Mosquito  eggs  can  hatch  only  in 
water.  Even  small  puddles  are  good  breeding  grounds.  Where 
eggs  have  been  laid  on  dry  land,  a  hard  rain  may  provide  sufficient 
moisture  for  them  to  develop.  The  water  must  remain  standing 
long  enough— from  two  to  three  weeks— for  egg,  larva,  and  pupa 
stages  to  be  completed  if  an  adult  is  to  emerge.  If  a  puddle  dries 
up  in  less  time,  the  insects  die. 

A  female  mosquito  lays  a  mass  of  from  fifty  to  several  hundred 
eggs.  The  larvae  that  develop  from  these  eggs  are  aptly  known 
as  "wrigglers."  The  pupae,  or  "tumblers,"  are  also  lively  in  the 
water  and  move  about  lashing  their  tail-like  abdomens.  Though 
they  require  no  food,  they  must  have  air,  and  frequently  come 


The  Wonderful  Ways  of  Insects  and  Spiders  [  269 

to  the  surface  of  the  water  to  inhale  through  their  short  breathing 
tubes. 

Crane  Flies:  Often  a  child  believes  that  he  has  discovered  a  giant 
mosquito  when  he  sees  a  long-legged,  gangling  creature  awkwardly 
drifting  through  the  air.  The  chances  are  it  is  a  crane  fly— an 
absolutely  harmless  insect.  In  spring  and  autumn  you  may  see 
large  swarms  of  crane  flies  dancing  a  few  feet  above  the  ground 
or  water. 

The  Dragonfly— Beautiful,  and  Useful  Too 

"Devil's  Darning  Needle"  and  Other  Nicknames 

Though  the  dragonfly  is  one  of  the  most  beautiful  of  all 
insects,  and  harmless  as  well,  it  may  terrify  a  small  child  who  has 
heard  some  of  its  nicknames  and  the  old  fables  in  which  they 
originated.  "Devil's  darning  needle"  recalls  the  old  superstition 
that  this  insect  can  sew  up  children's  ears;  "mule-killer"  reminds 
us  that  the  dragonfly  was  once  believed  to  kill  livestock.  The 
name  "snake-doctor"  was  inspired  by  the  weird  notion  that  it 
brought  dead  water  snakes  to  life. 

An  Underlip  With  Claws:  However,  "mosquito  hawk"  is  a  well- 
deserved  title,  for  dragonflies  in  their  nymphal  stage  (spent  in 
water)  eat  quantities  of  mosquito  larvae.  As  an  adult,  a  dragonfly 
catches  all  sorts  of  insects  on  the  wing— flies,  honeybees,  butter- 
flies, and  sometimes  other  dragonflies  smaller  than  itself.  The 
nymph  has  a  long  underlip  that  folds  back  between  its  front 
legs.  When  it  approaches  a  victim  this  lower  lip  shoots  out 
rapidly  and  grasps  the  prey  with  two  claws  that  form  a  pair  of 
pincers  at  its  end.  Though  it  is  a  serious  threat  to  mosquitoes 
and  other  insects,  the  dragonfly  neither  stings  nor  bites  people. 

The  Metamorphosis  of  the  Dragonfly:  If  yours  is  a  family  of  early 
risers,  you  may  some  day  thrill  to  the  memorable  sight  of  a 
dragonfly  emerging  from  its  nymph.  You  would  have  to  go 
exploring  along  the  edge  of  a  pond  about  six  o'clock  of  a  summer 
morning  and  watch  carefully  for  one  of  the  grotesque  nymphs 


270  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

crawling  out  of  the  water,  up  a  tree  trunk,  water  plant,  or  other 
support. 

Sure  of  its  support,  it  now  strains  at  its  armor-like  covering  until 
the  skin  of  its  back  splits  along  its  length;  then  very  carefully 
it  begins  to  pull  its  soft  body  from  the  shell.  When  this  has  been 
accomplished,  the  two  pairs  of  transparent,  glistening  wings 
expand  and  harden.  Sometimes  these  wings  are  beautifully  tinted 
in 'blue  and  brown.  The  insect  has  an  elongated  body,  and  its 
great,  compound  eyes  cover  almost  the  entire  surface  of  its  head. 

The  Damsel  Fly:  It  is  quite  a  puzzle  to  distinguish  the  dragonfly 
from  its  close  relative  the  damsel  fly.  They  are  alike  in  many 
ways,  but  the  dragonflies  have  larger  bodies  and  are  stronger  fliers. 
Also,  the  dragonfly  always  holds  its  wings  outstretched  when  rest- 
ing, whereas  a  damsel  fly  holds  its  wings  together  over  its  back. 

Insects  that  Live  in  the  Water 

The  Whirligig— "Lucky  Bug" 

Summer  outings  are  a  lot  more  fun  for  your  children  if 
they  can  make  the  acquaintance  of  some  of  the  odd  little  creatures 
found  in  ponds  and  streams.  One  of  the  most  easily  observed  is 
the  whirligig,  a  dark,  small  beetle.  You  may  see  the  whirligig 
spinning  or  skating  in  circles  on  the  surface  of  the  water.  It  is 
known  by  such  charming  nicknames  as  "lucky  bug,"  "submarine 
chaser,"  and  "write-my-name." 

Usually  you  find  whirligigs  in  groups,  sometimes  made  up  of 
hundreds  of  individuals.  If  they  are  alarmed,  they  make  a  sudden 
dive  to  the  bottom.  They  prefer  shade  to  bright  sunshine  and 
may  sometimes  be  found  out  of  water,  resting  on  sticks  or  rocks. 

The  whirligig's  eyes  are  worth  special  notice;  each  is  divided 
so  that  the  upper  half  looks  into  the  air  while  the  lower  part 
looks  down  into  the  water!  Its  legs  are  also  specialized,  the  middle 
and  hind  ones  being  broad  and  oarlike,  while  the  front  pair  are 
long  and  slender.  Another  strange  feature  of  the  whirligig  is  that 
if  you  hold  one  in  your  hand  for  a  time,  you  will  find  it  gives  off 
a  white  milky  fluid  with  a  smell  recalling  that  of  ripe  apples. 


The  Wonderful  Ways  of  Insects  and  Spiders  [271 

This  accounts  for  such  local  names  as  "apple  bug"  and  "vanilla 
bug." 

The  Speedy  Water  Strider 

Water  striders,  usually  found  in  fresh  or  brackish  water, 
have  very  long  slender  middle  and  hind  legs.  It  is  difficult  to 
capture  them,  as  they  skate  away  with  great  speed.  The  middle 
pair  of  legs  propel  this  bug  over  the  water  while  the  hind  pair 
steer.  Its  color  is  a  dull  dark  brown  above,  with  a  silvery-white 
underside. 

The  Upside-Down  Bug 

Another  water  insect,  the  back  swimmer,  is  named  for 
its  habit  of  swimming  on  its  back,  which  is  shaped  like  the  bottom 
of  a  canoe.  You  may  first  notice  it  as  it  hangs  head  downward  in 
the  water;  but  when  it  is  alarmed,  it  propels  itself  swiftly  away 
—bottom  side  up!— pushing  with  its  hind  legs. 

The  more  common  species  are  about  half  an  inch  long,  and 
have  enormous  compound  eyes.  The  back,  which  you  do  not 
see  when  they  are  swimming,  is  pearly-colored;  the  underside, 
which  you  do  see,  is  darker.  The  back  swimmer  is  easily  con- 
fused with  the  water  boatman,  which  is  quite  similar  in  appear- 
ance; but  the  boatman  is  smaller  and  never  swims  on  its  back. 
All  these  bugs,  with  the  exception  of  some  wingless  water  striders, 
fly  at  night  and  are  strongly  attracted  to  lights. 

The  Caddis  Fly  and  Its  PROTEcrrvE  Covering 

Among  the  fascinating  population  of  ponds  and  streams 
there  are  some  creatures  which,  like  the  dragonfly,  spend  their 
early  life  in  the  water  and  then,  as  adults,  proceed  to  live  on  land 
and  in  the  air.  Look  in  shallow  pools  for  one  of  the  most  interest- 
ing of  these.  At  first  you  may  see  what  appears  to  be  a  stick,  one 
or  two  inches  long  and  half  an  inch  around.  If  it  starts  to  move 
itself  along  the  bottom  or  up  the  stem  of  a  plant,  you  know  it  is 
"animal"  rather  than  "vegetable." 

This  is  the  larva  of  a  small  mothlike  insect  called  the  caddis 
fly.  Many  caddis  fly  larvae  make  cases  of  pebbles,  sticks,  or  other 


272  ] 


The  Wonderful  Ways  of  Insects  and  Spiders 


materials,  as  a  protective  covering  for  their  caterpillar-like  bodies. 
Those  that  use  sticks  are  said  to  construct  "log  cabins."  More 
commonly  they  use  sand  or  bits  of  vegetable  matter  which  adhere 
to  their  bodies  with  silk  produced  by  certain  glands. 


THE  CADDIS  FLY -NATURE'S  MASTER  BUILDER 

In  the  larval  stage  this  small  mothlike  insect,  living  at  the  bottom  of  a  pond  or 
stream,  builds  a  case  about  itself  from  bits  of  plants  or  pebbles.  (Both  types  are 
pictured  underwater.)  The  cases,  held  together  with  gluelike  silk  provided  by  the 
creature's  secretions,  are  remarkable  for  their  skillful  construction. 


Still  another  interesting  product  of  some  caddis  worms  is  a 
silken  net.  The  insect  anchors  this  so  that  the  cup-shaped  interior 
faces  upstream.  Thus  the  net  serves  both  as  protection  against  the 
current  and  as  a  food  trap  for  the  caddis  worm  that  fashioned  it. 

The  caddis  fly  emerges  from  its  pupal  form  in  a  manner  differ- 
ent from  that  of  most  water  insects.  The  usual  way  is  for  them 
to  leave  the  water  before  they  attain  adult  form;  but  the  caddis 
fly  emerges  at  the  bottom  of  the  stream  and  swims  to  the  surface. 


The  Wonderful  Ways  of  Insects  and  Spiders  [  273 

There  it  usually  grasps  some  object,  climbs  on  it  and  waits  for 
its  wings  to  dry. 

The  Fisherman's  Friend:  A  knowledge  of  these  interesting  insects 
is  of  practical  value  to  the  child  or  grown-up  who  wishes  to  do 
"fly-fishing"  in  ponds  and  streams.  As  part  of  this  fascinating 
sport  the  fisherman  uses  nymphs,  "wet  flies,"  and  "dry  flies"  to 
duplicate  the  caddis  fly  in  all  its  stages.  He  may  make  these  with 
such  materials  as  bits  of  feather  and  hair;  but  even  if  he  buys 
them  commercially,  he  ought  to  have  a  knowledge  of  the  fly  and 
its  habits  in  order  to  make  the  best  use  of  his  bait. 

How  to  Keep  Water  Insects  at  Home 

Housing  the  Captives 

One  of  the  most  enjoyable  ways  for  a  child  to  observe  the 
activities  and  development  of  water  insects  is  to  have  an  insect 
aquarium.  You  can  keep  a  few  specimens  in  jars  or  buckets;  but 
a  rectangular  glass  aquarium,  which  is  available  at  a  pet  store, 
makes  a  much  better  home  because  you  can  reproduce  the  crea- 
tures* natural  surroundings  in  miniature. 

Cover  the  bottom  with  a  layer  of  sand  about  an  inch  and  a 
half  thick,  first  taking  the  precaution  of  baking  it  to  kill  any 
bacteria.  Next,  fill  the  aquarium  about  two-thirds  full  with  water; 
then  plant  water  cress,  eel  grass,  chara,  or  other  green  plants,  an- 
choring them  securely  in  the  sand.  If  you  expect  to  house  nymphs, 
you  will  want  to  have  sticks  fastened  at  the  bottom  of  the  aquarium 
and  extending  a  few  inches  over  the  surface  of  the  water;  when  the 
nymphs  are  ready  to  be  transformed  into  winged  adults,  they  can 
crawl  on  the  sticks. 

Capturing  Water  Insects:  To  collect  specimens,  use  a  large  kitchen 
strainer  or  a  net  smaller  than  the  type  employed  for  collecting 
insects  in  the  air.  At  a  shallow  edge  of  a  pond,  where  the  reeds 
are  plentiful,  sweep  the  net  a  few  inches  above  the  muddy  bottom. 
Examine  your  catch  and  drop  interesting-looking  specimens  into 
various  jars,  adding  some  of  the  pond  water.  Try  to  keep  different 
kinds  separate  as  a  precaution  against  any  flesh-eating  species 
devouring  their  fellow  captives  on  the  way  home. 


274  ]  ^^^  Wonderful  Ways  of  Insects  and  Spiders 

How  to  Feed  Water  Insects:  When  you  collect  your  specimens,  it 
is  wise  to  take  extra  insects  to  serve  as  food.  You  can  also  obtain 
food  by  sweeping  an  insect  net  through  weeds  and  tall  grass. 
Often  the  flesh-eating  nymphs  will  eat  tiny  bits  of  meat.  This 
should  be  tied  to  a  string  and  pulled  out  again  if  it  has  not  been 
eaten  by  the  next  day.  If  you  wish  to  keep  both  flesh-eating  and 
plant-eating  species,  you  will  need  more  than  one  aquarium. 

An  insect  aquarium  should  be  located  in  a  bright  spot,  but 
not  directly  in  the  sunlight.  Keep  the  inner  sides  of  the  glass 
cleaned  with  a  piece  of  flannel  wrapped  about  a  stick.  This  will 
give  you  good  "observation  windows"  through  which  to  see  a 
caddis  worm  building,  a  dragonfly  nymph  snatching  at  prey  with 
its  long,  hinged  lip,  or  the  tiny  larva  of  a  whirligig  creeping 
stealthily  over  the  bottom  as  it  looks  for  other  larvae  to  eat.  And 
if  you  successfully  keep  them  to  maturity,  you  will  have  the  added 
thrill  of  observing  them  transformed  from  underwater  "per- 
sonalities" to  winged  creatures  of  the  air. 

Insect  Oddities 

The  Gauls— Weird  Homemakers 

Insects  provide  many  of  nature's  most  remarkable  oddities. 
You  have  discovered  one  of  them  when  you  observe  a  curious 
"bump"  or  ball  on  a  plant  stem  or  flower,  reminding  you  of  a 
large  nut  growing  on  a  tree  branch  or  leaf.  It  may  be  greenish, 
brown,  pink,  or  red.  If  you  were  to  cut  open  one  of  these  bumps, 
you  would  discover  an  insect  larva  at  its  center.  This  identifies 
it  as  a  **gall,"  the  home  of  a  growing  creature  that  will  develop 
into  a  small  wasp,  fly,  or  moth. 

The  young  nature  observer  is  likely  to  be  puzzled  by  the  im- 
prisoned larva.  "How  does  it  get  in  there?  I  don't  see  any  opening 
from  the  outside." 

How  a  Gall  Insect  Develops:  Actually,  the  larva  doesn't  "get  in"; 
its  home  grows  about  it!  Let  us  follow  the  life  cycle  of  one  of  the 
common  gall  insects— a  very  small  wasp  responsible  for  the  "oak 
apple."  In  early  spring  we  see  it  deposit  its  eggs  on  the  leaf  of  a 
scarlet  oak.  When  one  of  these  eggs  develops  into  a  legless  and 


The  Wonderful  Ways  of  Insects  and  Spiders  [  275 

almost  colorless  larva,  we  note  an  immediate  change  in  the  leaf. 
Vegetable  fibers  start  to  grow,  radiating  out  from  the  little  grub. 
As  this  process  goes  on,  a  thin  smooth  crust  forms  around  the 
outer  edges. 

Now  the  "oak  apple"  is  formed,  and  the  insect  larva  is  com- 
pletely surrounded  by  food  and  protected  by  its  globular  house. 
Here  it  eats,  completes  its  growth,  changes  to  a  pupa,  and  at  last 
emerges  as  a  wasp,  no  more  than  a  quarter-inch  in  length. 

Remarkable  Types  of  Galls:  The  "apple  oak"  is  but  one  of  the 
many  kinds  of  galls.  Thus,  you  may  frequently  see  two  different 
types  on  goldenrod  stems.  One  of  them,  made  by  a  grub  that 
becomes  a  fly,  is  spherical  in  shape;  the  other,  which  is  spindle- 
shaped,  develops  into  a  tiny  moth. 

Then  there  are  the  willow  cone  galls,  produced  by  a  little 
gnat.  It  lays  its  eggs  on  the  tip  of  the  bud  of  a  twig.  This  stops 
the  further  growth  of  the  twig,  stunting  the  leaves  into  small  scales 
which  overlap  in  rows  around  the  larva.  The  very  pretty  galls 
which  you  may  find  on  wild  rosebushes  somewhat  resemble  small 
chestnut  burs  but  are  pink  and  green  when  young.  Later  they 
turn  brown. 

Collecting  Galls:  In  wintertime,  collecting  galls  makes  a  fine  out- 
door activity.  Many  of  them  are  dead  and  deserted  by  then,  to  be 
sure;  but  in  some  the  grubs  are  still  resting  and  waiting  for  the 
onset  of  warm  weather.  The  collector  will  find  it  rewarding  to 
compare  styles.  A  gall  may  be  large  or  small,  globular  or  spindle- 
shaped;  its  covering  may  be  smooth,  shingled,  or  spiny.  You  can 
succeed  in  identifying  the  insect  builder  once  you  become  familiar 
with  these  variations  and  the  kinds  of  plants  that  each  insect 
characteristically  chooses. 

The  Interestingly  Named  Ant  Lions 

The  larva  of  the  ant  lion,  one  of  nature's  most  remarkable 
oddities,  catches  its  prey  in  a  trap.  It  is  fairly  easy  to  find  the 
traps  it  builds,  for  ant  lions  live  on  sandy  stretches  over  most  o£

the  United  States  and  southern  Canada.  As  in  the  case  of  the  gall 
insects,  the  adult  forms  are  undistinguished;  it  is  the  larvae, 
often  called  doodlebugs,  that  attract  our  attention. 

The  Doodlebug's  Ambush  Technique:  The  doodlebug,  plump- 
bodied  and  hairy,  is  less  than  an  inch  long.  Its  head  is  small  in 
proportion  to  its  body— but  its  jaws  are  enormous  in  relation  to 
the  size  of  its  head!  It  digs  a  pit  in  sandy  or  powdery  soil  by 
shoveling  the  earth  on  its  head  and  then  with  a  sharp  jerk,  throw- 
ing it  a  considerable  distance.  As  it  digs,  it  walks  around  and 
around,  always  backwards,  in  ever-widening  circles. 

Finally  a  tiny  crater  is  formed,  an  inch  and  a  half  across  or 
smaller,  with  the  doodlebug  buried  at  the  bottom.  With  only 
its  head  and  powerful  jaws  exposed,  it  waits  for  an  ant  or  some 
other  insect  to  slip  over  the  edge  and  slide  down.  Then  it  seizes 
the  victim,  makes  it  helpless  by  injecting  a  paralyzing  secretion 
into  it,  sucks  the  juice  from  its  body,  and  flips  the  lifeless  remains 
out  of  the  pit  by  an  upward  jerk  of  its  long  jaws. 

How  to  Find  Doodlebugs:  You  may  be  interested  in  observing 
this  extraordinary  example  of  how  a  * 'lowly"  creature  can  capture 
its  prey  by  an  ingenious  trapping  technique.  You  can  catch  a 
doodlebug  by  finding  its  crater  and  scooping  your  hand  under  to 
bring  the  insect-excavator  to  the  surface.  Place  it  in  a  box  of 
sandy  soil  and  you  will  quickly  see  it  set  to  work.  If  you  wish 
to  see  the  final  act  of  the  drama,  you  must  place  ants  or  other 
insects  in  the  box  so  the  doodlebug  will  not  vainly  lie  in  wait. 

The  Strange  Praying  MANxros 

I  know  of  one  little  girl  to  whom  the  praying  mantis  will 
always  seem  curious  if  only  because  of  the  way  she  first  became 
acquainted  with  this  insect.  On  an  August  evening  a  mantis 
alighted  on  a  window  sill  of  her  New  York  apartment!  It  would 
be  hard  to  imagine  a  more  unlikely  intruder  in  such  a  place  than 
this  queer  green  creature  with  its  pointed,  elfin  face  and  big 
round  eyes. 

The  little  girl  managed  to  get  it  into  a  box  and  took  it  to  the 
American  Museum  of  Natural  History  in  New  York  in  the  belief 


The  Wonderful  Ways  of  Insects  and  Spiders 


[277 


that  she  had  something  on  the  order  of  a  visitor  from  Mars.  There 
she  learned  the  true  nature  of  her  captive,  and  also  that  it  was 
quite  possible  to  keep  a  mantis  as  a  pet. 

The  Preying  Habits  of  the  Praying  Mantis:  In  natural  surround- 
ings mantids  are  great  hunters,  capturing  by  stealth  such  lively 
insects  as  butterflies,  mosquitoes,  grasshoppers,  beetles,  and  flies. 
The  mantis  lies  in  wait  with  its  front  legs  upraised  in  a  prayerful 
pose,  and  when  its  prey  comes  near,  it  snatches  at  the  victim  with 
lightning  speed.  The  prey  has  slight  chance  of  escaping  the  rows 
of  sharp  spines  on  the  second  and  third  joints  of  the  mantis' 
forelegs. 


"MUIE-KILLERS"  AND  ''DEVIL'S  HORSES" 

These  are  some  of  the  epithets  that  have  been  applied  to  the  praying  mantis, 
though  its  forelegs  seem  to  be  raised  in  a  devout  attitude,  the  mantis  is  actually 
poised  to  pounce  on  its  prey.  Then,  holding  its  victim  in  a  grip  of  steel,  it  devours 
it  at  its  leisure.  Green  or  brown   in  color,  this   insect  is   about   two   inches   long. 


278  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

How  to  Feed  a  Praying  Mantis:  In  captivity  a  mantis  will  usually 
accept  bits  of  hamburger  and  other  meat  as  substitutes  for  living 
prey.  Mantids  vary  quite  a  bit  in  their  eating  habits;  some  are 
known  to  drink  milk  while  others  refuse  it.  They  should  be 
watered  every  day,  and  you  can  do  this  by  sprinkling  water  on 
leaves  in  their  cage.  In  time  they  may  become  tame  enough  to 
drink  the  water  off  a  spoon. 

During  the  winter,  mantids'  brownish  egg  cases,  about  the  size 
of  walnuts,  may  be  collected  from  weeds  and  bushes.  In  the  spring 
at  least  a  couple  of  hundred  babies  will  emerge  from  one  of  them. 

The  Mantis  as  a  Pest  Exterminator:  The  mantids  of  our  southern 
states  are  native  to  this  country,  but  one  species  found  commonly 
in  the  more  northerly  regions  originally  came  from  China  and 
Japan,  while  another  is  an  import  from  Europe.  Both  were  in- 
troduced here  by  accident;  later  more  were  imported  for  their 
supposed  value  in  destroying  insect  pests.  In  China  they  are 
sometimes  tied  by  a  silk  thread  near  a  bedroom  window  where 
they  trap  flies  and  mosquitoes. 

Walking  Sticks— Masters  of  Camouflage 
A  youngster  must  be  really  sharp-eyed  to  discover  one  of 
these  remarkably  camouflaged  insects.  Aside  from  the  fact  that  its 
coloring  blends  with  the  tree  bark  on  which  it  so  often  rests,  the 
ivalking  stick  has  much  the  same  shape  as  a  slender  twig.  Unless 
it  moves,  you  can  scarcely  tell  it  is  an  animal!  In  North  America 
you  will  never  see  one  flying,  as  all  our  species  are  wingless;  but 
some  of  the  tropical  kinds  have  wings. 

When  a  walking  stick  is  detected  and  picked  up,  it  is  quite 
capable  of  playing  dead— sometimes  for  several  hours  at  a  stretch. 
Though  the  largest  American  species  is  about  six  inches  long, 
including  the  antennae,  some  found  in  India  are  known  to  reach 
a  length  of  fifteen  inches.  Some  walking  sticks  are  able  to  grow 
a  new  leg,  at  least  partially,  to  replace  one  lost  through  a  mishap.

WHICH  IS  THE  WALKING  STICK,  WHICH  IS  THE  TWIG? 

This  aptly  named  insect  is  one  of  nature's  most  amazing  examples  of  camouflage. 
Its  color  follows  the  seasons:  green  in  springtime,  brown  in  autumn  to  blend  with 
the  changing  hues  of  the  leaves.  The  walking  stick  can  also  play  dead  for  several 
hours,  if  need  be.  It  feeds  on  leaves,  and  is  active  mostly  at  night. 

The  Misunderstood  Spiders 

Most  of  us  think  of  the  classic  struggle  between  the  spider  and 
the  fly  as  a  war  between  two  kinds  of  insects.  But  the  spider  is  not 
an  insect  at  all!  Your  youngster  can  discover  this  for  himself  if 
he  watches  one  closely  and  counts  its  legs.  The  spider  has  eight 
legs— two  more  than  an  adult  insect.  Another  distinction  is  that 
a  spider  has  only  two  major  body  divisions— the  head  and  thorax 
merged  into  one  unit,  and  the  abdomen— whereas  an  insect  has 
three.  Still  another  difference  is  that  a  spider,  unlike  an  insect, 
has  no  antennae. 

The  Spider's  Poisonous  Bite 

Spiders  are  widely  misunderstood,  much  as  snakes  are. 
Many  people  believe  that  all  spiders  should  be  avoided  or  killed, 
that  a  spider  bite  is  often  fatal.  In  the  United  States  we  must 
beware  of  iust  two  kinds:  the  tarantula  and  the  black  widow.  Even 


28o  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

in  the  case  of  these  two  species,  the  deadliness  of  the  bite  has  been 
greatly  exaggerated.  If  victims  are  properly  treated,  they  recover 
promptly. 

It  used  to  be  thought  that  black  widows  were  found  only  in 
the  South,  but  they  are  constantly  being  discovered— and  always 
with  great  surprise— in  New  York,  Connecticut,  and  other  north- 
ern states.  The  large,  hairy  tarantula  (the  banana  spider)  also 
occasionally  appears  up  north,  after  traveling  as  a  stowaway  in  a 
bunch  of  bananas.  In  the  tropics  tarantulas  are  constantly  on  the 
prowl  among  this  fruit  for  roaches  and  other  insect  food;  so, 
chances  are  strong  that  a  certain  number  will  be  moved  aboard 
ship. 

The  bite  of  ordinary  spiders  is  poisonous— that  is  the  way  they 
kill  for  food.  Some  bites  cause  swelling  and  irritation,  possibly 
to  the  extent  produced  by  a  wasp's  sting.  However,  the  poison  is 
usually  administered  in  minute  quantities;  and  few  spiders  are 
strong  enough  to  be  able  to  bite  through  a  human  skin  even  if 
they  tried. 

Styles  in  Spider  Traps 

Spiders  are  past  masters  at  keeping  out  of  sight,  but  we 
have  little  trouble  finding  the  silken  traps  they  weave.  Thus  we 
rarely  see  the  little  house  spider  that  prefers  life  indoors;  still, 
we  know  it  has  been  about  when  we  discover  cobwebs  in  dark 
and  undisturbed  corners.  The  funnel-shaped  webs  you  may  see 
spread  over  the  fields  if  you  go  for  an  early-morning  walk  are  the 
work  of  grass  spiders. 

A  close  relative  of  this  species  frequents  cellars,  so  it  is  not 
surprising  to  find  the  same  kind  of  funnel-shaped  webs  in  your 
cellar.  The  most  exquisite  of  all  webs  are  those  constructed  by  the 
orb  builders,  which  often  do  their  weaving  in  gardens  or  on 
porches. 

Remote-control  Traps:  Sometimes  you  may  find  an  orb  weaver 
stationed  at  the  center  of  its  web,  waiting  for  its  prey;  some  species 
make  a  habit  of  this.  Others,  however,  keep  themselves  hidden 
nearby.  A  spider  that  remains  away  from  its  web  rests  one  of  its 


The  Wonderful  Ways  of  Insects  and  Spiders  [281 

claws  on  a  trap  line  stretched  from  the  hub  of  the  web.  When  an 
insect  enters  the  trap,  the  resulting  vibration  is  carried  to  the 
spider,  which  rushes  onto  the  web  and  envelops  its  victim  in  a 
band  of  silk.  It  bites  the  insect  either  before  or  after  wrapping  it, 
but  usually  does  not  eat  it  at  once  unless  it  is  hungry. 

How  the  Spider  Ingeniously  Avoids  its  Own  Trap:  A  child  may 
wonder,  even  if  he  has  the  opportunity  to  watch  this  drama  being 
enacted,  why  the  spider  does  not  become  entangled  in  its  own 
web.  He  will  understand  why,  if  he  knows  that  a  web  is  made  of 
two  kinds  of  silk.  One  kind  is  inelastic  and  does  not  stick  to  objects 
that  touch  it;  the  other  is  very  elastic  and  sticky. 

The  spokes  of  the  web,  the  framework,  and  the  guy-lines  that 
fasten  it  to  surrounding  objects,  are  all  of  the  inelastic  silk.  How- 
ever, the  continuous  spiral  lines  connecting  the  spokes  are  very 
elastic  and  adhere  to  anything  that  touches  them.  The  spider 
cleverly  runs  along  the  spokes  and  thereby  avoids  being  tangled 
in  its  own  web. 

How  the  Spider  Spins  an  Orb  Web:  If  the  spider  is  unlucky  its 
web  may  be  destroyed  many  times  during  a  season.  At  times  the 
little  weaver  may  have  to  construct  one  every  twenty-four  hours. 
It  begins  its  work  on  a  well-elevated  position  by  spinning  a  thread 
of  silk  which  is  soon  caught  in  a  passing  breeze;  the  free  end  is 
carried  along  until  it  reaches  an  object  to  which  it  adheres.  The 
spider  then  draws  in  the  slack,  making  the  line  taut.  It  fastens  the 
second  end  and  walks  across  it,  doubling  its  strength  with  another 
line  of  silk. 

The  spokes  are  constructed  next,  extending  outward  from  a 
central  point  on  this  bridge  line.  Now  the  spider  makes  a  spiral 
line  a  short  distance  out  from  the  hub  of  these  spokes  and  attached 
to  each  of  them,  holding  them  firm.  The  spider  pulls  this  line 
tight,  then  continues  weaving  spiral  lines  until  it  reaches  what 
will  be  the  outer  edge  of  the  orb. 

Up  to  this  point  all  the  silk  has  been  smooth,  tough,  and  not 
sticky.  Now  elastic,  adhesive  silk  is  manufactured  as  the  spider 
makes  a  second  series  of  spirals,  this  time  working  from  the  outer 
edge  of  the  web  down  to  the  hub.  During  this  process  the  spider 


282  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

cuts  the  first  spirals  with  its  jaws  so  that  these  lines  fall  away  from 
the  web.  They  have  served  their  purpose  as  a  mere  scaffold!  If 
you  look  very  closely  at  a  web,  you  may  possibly  see  bits  of  the 
temporary  spiral  clinging  to  the  spokes. 

Built-in  Silk  Spinner:  What  the  spider  succeeds  in  spinning  is  so 
extraordinary  that  the  result  is  quite  certain  to  cause  an  observant 
child  to  wonder  just  how  the  silk  is  produced.  This  is  the  explana- 
tion: A  spider  has  special  spinning  organs  located  near  the  top 
of  its  abdomen  (in  contrast  to  a  caterpillar,  which  has  its  near  the 
lower  lip) .  There  are  two  or  three  of  these  finger-like  spinnerets, 
tipped  with  many  small  tubes.  The  silk  is  spun  from  them  as  a 
fluid  but  it  hardens  immediately  upon  coming  in  contact  with  the 
air. 

Spiders  in  Ambush:  Not  all  spiders  construct  webs;  some  kinds 
merely  lie  in  wait  for  their  prey.  You  may  find  white  crab  spiders 
doing  this,  though  it  is  not  easy  to  detect  one  of  them.  They  are 
great  artists  at  camouflage,  taking  on  the  color  of  the  various 
flowers  they  hide  in.  Another  spider  that  dispenses  with  a  web 
is  the  trap-door  spider,  which  makes  a  silk-lined  home  in  the 
earth  from  which  to  stalk  victims. 

How  to  Watch  Spiders  at  Work:  You  may  occasionally  succeed 
in  moving  an  orb  web  with  its  weaver  to  your  home,  if  it  happens 
to  be  attached  to  a  branch  that  you  can  break  off  conveniently. 
If  you  set  it  on  a  porch  or  some  other  likely  place,  you  can  then 
observe  it  at  your  convenience.  However,  it  is  more  adventurous 
to  watch  spider  traps  being  prepared  in  their  natural  setting. 

You  may  have  a  chance  to  do  this  while  you  take  an  evening 
walk  with  your  child;  late  in  the  day  is  the  spider's  usual  time 
for  spinning.  You  can  even  plot  to  have  a  web  built  as  you  look 
on.  If  you  find  one  during  the  day  with  its  builder  lying  in  wait 
nearby,  break  it  quietly  and  gently  so  as  not  to  frighten  the  spider 
into  running  away.  Then  return  to  the  scene  during  "building 
hours"  and  you  should  see  a  new  web  under  construction.

Spider  Mothers  Are  Resourceful 

Spiders  have  still  another  use  for  their  silk.  Eggs  laid  in 
the  autumn  to  hatch  in  the  spring  need  protection  from  weather 
as  well  as  from  hungry  creatures.  Many  spiders  solve  this  problem 
by  spinning  elaborate  silken  sacs  for  their  eggs.  Those  that  make 
cobwebs  often  suspend  the  sac  from  the  web— or  they  may  place 
the  sac  in  a  more  sheltered  spot.  Others  make  nests  for  their  eggs 
in  folded  leaves,  or  in  the  crevices  of  rocks  and  boards.  Another 
custom  is  to  nest  on  stones  and  cover  the  nest  and  eggs  with  a 
smooth,  waterproof  silken  coat. 

You  may  frequently  see  these  little  silvery  disks  as  you  walk 
through  the  fields  in  autumn.  The  large  running  spiders  that  you 
are  most  likely  to  find  under  stones  not  only  make  egg  sacs— the 
mother  attaches  the  sac  to  her  spinnerets  and  carries  it  everywhere. 
When  the  young  hatch,  they  climb  on  her  back  and  stay  with  her 
for  some  time. 

Cannibal  Spiders:  Even  a  mother's  care  cannot  prevent  her  off« 
spring  from  devouring  each  other.  One  of  the  common  orb 
weavers,  the  orange  garden  spider,  makes  a  very  fine  sac,  about 
as  large  as  a  hickory  nut,  in  which  she  may  lay  five  hundred  eggs 
or  more.  These  hatch  early  in  the  winter  but  the  young  remain 
within  the  protective  walls  of  the  sac.  By  spring,  when  the  sac 
breaks  open,  only  a  dozen  or  so  young  may  emerge.  They  are 
the  strong  ones  that  have  survived  by  consuming  the  rest  of  the 
once-large  family. 

"Flying"  Spiders 

Possibly  you  have  had  the  disconcerting  experience  of  hav- 
ing a  very  tiny  spider  "fly"  in  your  face  on  occasion.  Particularly 
in  the  spring  and  autumn  great  numbers  of  these  eight-legged 
creatures  sail  through  the  air  and,  especially  to  a  youngster,  it 
may  seem  they  are  actually  flying. 

However,  if  you  look  closely,  you  will  see  that  the  spiderling 
is  attached  to  a  long  thread— still  one  more  use  for  silk!  Aided  by 
the  thread,  it  makes  use  of  rising  air  currents  to  float  from  its 
hatching  place  to  new  territory,  well  apart  from  its  numerous 
and  hungry  brothers  and  sisters. 


284  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

The  Spider's  Homemade  Parachute:  To  start  its  journey,  the 
young  spider  climbs  up  a  tall  blade  of  grass  or  a  larger  plant. 
There  it  spins  a  silken  thread  and  sends  it  out  on  the  air.  When 
it  is  long  enough,  the  friction  of  air  currents  on  it  buoys  it  up- 
ward, and  the  spider,  letting  go  its  hold,  is  off  on  its  journey  to 
an  unknown  destination.  Usually  the  flight  is  ended  by  the  spider's 
bumping  against  an  elevated  object,  but  sometimes  it  helps  decide 
its  own  fate  by  pulling  in  the  streamer  till  all  buoyancy  is  lost. 
'Tlying"  spiders  have  been  discovered  in  mid-ocean! 

Flying  or  ballooning  is  not  the  habit  of  just  a  few  kinds  of 
spiders.  Most  species  use  this  means  of  getting  from  one  area  to 
another. 

Daddy  Longlegs 

If  you  observe  the  habits  of  this  creature  which,  like  the 
spider,  is  almost  "all  legs,"  you  will  find  that  it  does  not  have 
the  spider's  ways.  It  does  not  spin  silk,  and  it  lays  its  eggs  under 
stones  or  in  crevices  but  gives  them  no  other  protection.  Though 
it  has  eight  legs  and  in  many  other  ways  resembles  spiders,  it  is 
in  an  animal  division  of  its  own.  We  recognize  it  quite  easily  by 
its  hairlike  and  remarkably  long  legs.  If  our  legs  were  as  long  in 
proportion  to  our  bodies  as  "daddy's"  are  to  his,  we  would  stand 
something  like  forty  feet  off  the  ground! 

''Tell  Me  Where  the  Cows  Are":  Some  children  still  learn  the 
strange  old  custom  of  grasping  a  "daddy"  and  saying,  "Tell  me 
where  the  cows  are,  or  I'll  kill  you."  Its  waving  legs,  as  the  little 
creature  struggles  to  get  away,  are  directed  to  all  points  of  the 
compass,  so  that  if  there  are  some  cows  about,  they  are  sure  to 
be  indicated.  To  a  very  young  naturalist,  this  seems  a  satisfying 
experiment!  But  later  he  can  learn  facts  about  daddy  longlegs 
that  are  much  more  interesting  than  this  fanciful  idea. 

How  "Daddy"  Uses  His  Long  Legs:  This  creature  has  the  power 
of  regrowing  legs  if  they  are  broken  off.  The  several  pairs  are  of 
varying  lengths:  The  first  pair  is  usually  the  shortest,  the  second 
pair  the  longest  and  the  fourth  pair  next  in  length.  When  you 
watch  "daddy"  running  you  can  see  that  the  second  pair  of  legs 


The  Wonderful  Ways  of  Insects  and  Spiders  [  285 

are  spread  wide  apart  and  keep  in  rapid  motion.  Their  sensitive 
tips  serve  as  feelers  and  relay  information  about  the  nature  of 
the  animal's  surroundings.  If  they  pause  over  something  that  sug- 
gests food,  "daddy"  stops  running  to  investigate  further  with  the 
little  feelers   (palpi)   under  its  head. 

Observing  Daddy  Longlegs:  A  daddy  longlegs  makes  a  most  re- 
warding little  captive.  You  can  keep  one  for  a  while  by  simply 
putting  a  large  glass  tumbler  over  it.  Place  a  few  drops  of  sweet- 
ened water  within  convenient  reach  of  the  legs.  It  is  amusing  to 
watch  this  odd  creature  pull  one  leg  at  a  time  slowly  through  its 
jaws,  nibbling  it  clean.  A  child  can  also  see  a  little  black  dot  on 
top  of  its  body,  located  between  the  second  pair  of  legs,  which  is 
apparently  an  eye!  However,  by  examining  it  under  a  magnifying 
lens,  he  will  discover  that  this  is  a  raised  knob,  with  a  tiny  shining 
black  eye  on  either  side  of  it! 

''Thousand-Leggers" 

Children  often  call  these  creatures  "bugs"— but  they  are 
neither  bugs  nor  insects  of  any  kind.  They  are  in  the  same  major 
grouping  of  the  animal  kingdom  as  insects,  but  each  is  recognized 
as  a  separate  class  in  this  division.  This  is  quickly  indicated  by 
the  fact  that  centipedes  and  millipedes  have  many  pairs  of  legs— 
in  contrast  to  the  insects,  which  have  three  pairs  of  legs. 

More  About  ''Thousand-Leggers" :  Centipedes  and  millipedes  have 
two  main  parts  to  their  body  structure:  head  and  body.  The 
millipede  has  two  pairs  of  walking  legs  to  each  body  segment, 
whereas  the  centipede  has  one  pair  to  a  segment.  Their  size  and 
number  of  legs  vary  according  to  species,  but  all  species  of  milli- 
pedes have  so  many  legs  that  we  frequently  hear  them  called 
' '  thousand-leggers. ' ' 

We  usually  find  millipedes  in  damp  places,  though  they  may 
appear  almost  anywhere  in  a  garden.  They  feed  on  vegetable 
matter  and  they  do  not  bite.  If  they  are  disturbed,  they  roll  up 
into  a  spiral. 

The  centipedes  are  not  so  harmless.  They  have  a  pair  of  poison 
fangs  on  the  first  segment  of  the  flattened  body.  In  northern 


286  ]  •  The  Wonderful  Ways  of  Insects  and  Spiders 

regions  centipedes  are  small  and  generally  use  their  poison  for 
killing  insect  prey.  In  tropical  regions  there  are  larger  species  of 
centipedes;  their  bite  may  have  serious  consequences  for  human 
victims. 

The  Lowly  Worms 

Many  a  child  who  digs  earthworms  for  fishing  bait  thinks  he 
is  collecting  "insects."  This  idea  is  indeed  very  far  from  the  truth. 
Worms  are  not  closely  related  to  any  other  creature;  in  the  animal 
kingdom  they  occupy  their  own  major  niche,  just  as  distinct  as 
the  division  of  "vertebrates"  to  which  man  belongs. 

Scientists  have  classified  the  many  kinds  of  worms  in  three 
main  groups,  and  each  of  these  forms  one  of  the  eleven  major 
divisions  of  the  animal  kingdom.  Some  of  our  most  troublesome 
parasites,  such  as  tapeworms  and  hookworms,  belong  to  two  of 
these  divisions— "roundworms"  and  "flatworms." 

How  Earthworms  Enrich  the  Soil 

In  the  third  group  ("segmented  worms")  we  find  our  friend 
the  earthworm.  "Friend"  it  is  indeed,  for  earthworms  are  of  im- 
mense value  to  man  in  growing  food.  As  they  move  through  the 
ground  they  do  not  push  the  earth  around  their  bodies  as  a  mole 
does;  they  actually  swallow  it!  Before  they  expel  the  earth  again, 
it  is  ground  fine  in  the  gizzard  and  lime  is  added  to  it  in  the 
stomach. 

Earthworms  usually  plow  a  foot  or  more  beneath  the  surface 
of  the  earth,  and  are  constantly  bringing  subsoil  upward.  They 
also  carry  down  with  them  from  the  surface  bits  of  dead  leaves, 
flowers,  and  twigs,  which  enrich  the  soil  as  they  decay.  Charles 
Darwin  estimated  that  an  acre  of  garden  land  in  England  held 
more  than  fifty  thousand  earthworms,  and  that  eighteen  tons  of 
vegetable  mold  passed  through  each  earthworm's  body  every  year! 

Tug-of-War:  If  a  child  watches  a  bird  tugging  at  an  earthworm, 
he  may  wonder  what  enables  the  worm  to  "hold  on."  The  holding 
is  done  with  strong  muscles  aided  by  tiny  stiff  bristles  that  cling 
to  the  earth.  There  are  four  pairs  of  bristles  on  each  segment 


The  Wonderful  Ways  of  Insects  and  Spiders  [  287 

(or  ring)  of  the  worm's  body,  except  for  the  first  three  segments 
and  the  last  one.  The  bristles  are  aids  in  crawling  as  well  as 
holding. 

The  Earthworm's  Eggs:  In  the  giant  earthworms  of  the  tropics 
which  may  grow  to  a  length  of  six  feet,  it  is  easy  to  see  how  the 
body  is  composed  of  segments— one  behind  the  other.  On  the 
common  earthworm  an  extra,  saclike  ring  is  formed  about  the 
body  toward  its  tail-end.  The  worm  lays  its  eggs  in  this  ring,  and 
then  works  it  forward  and  over  its  head.  Cast  off,  the  ring  becomes 
a  football-shaped  capsule  of  yellowish  brown,  no  larger  than  a 
grain  of  wheat.  You  may  sometimes  come  across  such  a  capsule 
in  the  fields,  under  stones  or  sticks,  in  May  or  June,  before  baby 
earthworms  have  hatched  from  the  egg. 

Earthworms  Are  Profitable:  With  the  value  of  the  earthworm 
fully  recognized,  raising  worms  has  become  a  successful  business 
enterprise.  The  earthworms  are  sold  as  fish  bait  to  sportsmen 
throughout  the  United  States  and  Canada— and,  more  important, 
they  are  supplied  commercially  to  farmers  who  appreciate  their 
ability  to  increase  the  fertility  of  the  soil. 

The  Insect  World— Tiny  or  Immense 

We  have  come  to  the  end  of  our  exploration  of  the  enchanting 
world  of  insects,  spiders,  and  other  small  creatures.  It  is  a  world 
tiny  in  scale  but  brimming  over  with  fantastic,  "wonder-full" 
things  to  observe:  How  insects  see  with  their  curious  compound 
eyes,  how  they  walk  upside-down,  walk  backward,  swim  on  their 
back,  whirl  in  circles,  make  music,  and  change  into  gorgeous  crea- 
tures through  the  magic  of  metamorphosis;  how  they  make  paper, 
produce  honey,  and  weave  silk;  how  they  kill  by  piercing,  suck- 
ing, trapping,  entangling,  or  injecting  nerve-killing  fluid;  how 
they  build  nests,  combs,  webs— or  house  themselves  by  fashioning 
a  case  over  their  bodies;  how  they  live  in  huge  colonies  and  fight 
in  vast  armies  commanded  by  queens  and  served  by  slaves. 

Once  you  turn  from  man-made  structures  of  wood,  concrete, 
and  steel,  and  allow  your  eyes  to  dwell  on  nature  and  its  creatures, 
you  can  never  know  a  boring,  empty  moment.  There  is  so  much 


288  ]  The  Wonderful  Ways  of  Insects  and  Spiders 

to  see,  so  much  to  be  inquired  into  and  understood.  Exploring 
nature,  I  have  said  earlier,  is  a  natural  and  rewarding  outlet  for 
our  children's  energy  and  our  own.  It  opens  windows  on  the  world, 
through  which  the  tensions  produced  in  all  of  us  by  modern  liv- 
ing may  escape.  That  is  what  George  Orwell,  the  noted  British 
novelist  and  critic,  meant  when  he  declared:  "I  think  that  by 
retaining  one's  childhood  love  of  such  things  as  trees,  fishes, 
butterflies  and  .  .  .  toads,  one  makes  a  peaceful  and  decent  future 
a  little  more  probable." 


CHAPTER 


UThe  Fascination 
of  Flowers 


G 


HiLDREN  LOVE  things  that  grow.  That  is 
probably  why  few  toys  can  ever  hold  their 
attention  as  long  as  a  garden  will.  Everything  about  a  garden  ap- 
peals to  them.  Planting  a  seed  is  a  privilege  they  are  ready  to  fight 
for,  and  day  after  day  they  will  come  back  to  see  if  it  has  begun 
to  sprout.  Watching  a  bud  unfold  is  another  experience  that  fills 
them  with  wonderment.  It  is  no  exaggeration  to  say  that  the  young- 
ster who  does  not  have  his  own  garden  or  flower  box,  or  just  a 
single  flowerpot,  is  being  deprived  of  one  of  childhood's  most 
treasured  possessions. 

A  child's  interest  in  the  plant  world  is  by  no  means  limited  to 
flowers.  Vegetables  and  flowerless  plants,  or  even  grass,  will  absorb 
his  attention,  too,  and  he  will  give  them  devoted  care.  What 
attracts  him  to  plants  is  that  they  are  living  things,  growing,  ex- 
panding, changing. 

Once  your  youngster  becomes  fully  aware  that  plants  have 
life  just  as  animals  do,  a  number  of  questions  are  bound  to  arise 
in  his  mind  if  he  takes  nature  exploring  seriously.  Not  so  easy 
to  answer  as  it  is  to  ask  is  this  one:  "What's  the  difference  between 
plants  and  animals?" 

Plants  Move  Too:  The  younger  child  may  be  satisfied  with  the 
popular  answer— quite  oversimplified— that  animals  are  capable  of 
motion,  moving  from  place  to  place  by  their  own  efforts— whereas 

289 


290  1  The  Fascination  of  Flowers 

plants  cannot  move.  Often  this  answer  will  not  do  for  an  older 
child.  As  he  thinks  it  over,  he  may  realize  that  plants  do  move  in 
certain  ways. 

For  example:  They  move  upward  and  outward  as  part  of  the 
growing  process.  Some  develop  runners  that  creep  over  the  ground. 
Violets— and  others— shoot  their  seeds;  the  dandelion  is  one  of 
many  plants  that  parachute  seeds  to  new  growing  grounds,  while 
portions  of  the  stems  of  Florida  moss  break  off  and  are  blown 
about  by  the  wind  until  they  alight  and  start  to  grow.  The  water 
lily,  like  numerous  other  species,  closes  its  petals  each  night  and 
opens  them  again  in  the  morning.  (What  probably  impresses  chil- 
dren even  more  is  that  the  water  lily  floats.) 

So  we  see  there  is  plenty  of  motion  on  the  part  of  plants.  The 
older  child  will  conclude  that  many  characteristics  observed  in 
animals  are  also  present  in  plants.  Both  plants  and  animals  move; 
both  are  made  up  of  living  cells,  are  born,  breathe,  feed,  grow, 
and  reproduce  themselves. 

How  Plants  Feed  Themselves:  There  is  one  vital  difference  be- 
tween plants  and  animals,  however,  and  that  is  in  the  way  they 
feed  themselves.  A  plant  is  in  effect  a  factory  which  produces  its 
own  food  by  turning  nonliving  matter  into  living  matter.  This 
process,  one  of  nature's  wonders,  is  made  possible  by  the  green 
substance  known  as  chlorophyll. 

We  often  call  chlorophyll  "leaf-green,"  as  it  is  found  chiefly 
in  leaves.  When  this  leaf-green  is  worked  on  by  the  action  of  light 
from  the  sun,  chemical  changes  occur  which  transform  lifeless 

(inorganic)    matter  into   life-giving  and   life-sustaining  matter. 

(Animals  do  not  have  chlorophyll,  but  we  now  find  it  used  in  all 
kinds  of  products,  from  toothpaste  to  dog  food,  mainly  for  the 
purpose  of  killing  odors.) 

The  Leaf— Nature's  Great  Chemical  Laboratory 

If  you  examine  leaves,  you  will  notice  that  as  a  rule  they  are 
a  darker  green  on  the  upper  side  than  on  the  underside.  The 
chlorophyll-bearing  cells  on  the  top  surface  are  packed  more 
closely  to  catch  as  much  sunlight  as  possible.   (As  we  have  seen. 


The  Fascination  of  Flowers  [  29 1 

sunlight  is  one  of  the  "raw  materials"  needed  for  making  living 
matter.) 

The  "manufacturing"  cells  are  protected  on  top  and  bottom 
surfaces  by  a  skin,  or  epidermis,  which  is  perforated  with  innumer- 
able tiny  holes.  Each  hole  is  surrounded  by  two  guard-cells— the 
only  surface  cells  that  contain  chlorophyll.  Through  the  little 
holes  the  leaf  constantly  takes  in  and  gives  off  oxygen,  carbon 
dioxide,  and  other  gases  as  well  as  water  vapor.  -  - 

How  Chlorophyll  Makes  Food  for  Plants 

Before  the  leaf  "factory"  can  operate,  it  requires  one  more 
item.  This  is  a  watery  solution,  containing  many  substances,  that 
originates  in  the  soil,  enters  the  plant  roots,  works  its  way  up  the 
stem  and  at  last  into  the  leaf. 

Within  each  leaf,  carbon  dioxide— much  of  it  comes  from  the 
air  we  exhale— is  separated  into  carbon  and  oxygen.  In  the  same 
way,  water  is  broken  down  into  oxygen  and  hydrogen.  The  leaf 
cells  combine  the  carbon  with  the  hydrogen  and  oxygen  into  a 
form  of  sugar  that  will  nourish  the  plant.  It  is  the  chlorophyll 
that  accomplishes  this  remarkable  feat— but  it  can  be  done  only 
when  sunlight,  or  artificial  light  equal  to  sunlight,  is  shining  on 
the  plant. 

In  the  daytime  plants  are  our  benefactors  by  releasing  oxygen, 
which  purifies  the  air  we  breathe.  At  night,  though,  they  give 
off  carbon  dioxide,  a  gas  which  is  poisonous  when  it  is  present 
in  considerable  quantity.  (This  explains  why  a  room  with  many 
large  house  plants  should  be  well  aired  at  night.) 

A  scientist  has  estimated  that  during  the  course  of  a  summer 
a  single  leaf,  suitably  exposed  to  sunlight,  manufactures  enough 
sugar  to  cover  itself  with  a  solid  layer  about  one  twenty-fifth  of 
an  inch  thick— and  this  is  aside  from  protein  and  other  food 
elements! 

Plants  Turn  Toward  the  Sun:  Your  house  plants  will  give  you  a 
fine  opportunity  to  observe  how  leaves  are  affected  by  the  need 
for  sunlight,  in  order  to  continue  feeding  the  plants.  Even  a  small 
child  can  observe  how  the  location  of  the  leaves  at  or  near  the  ends 
of  branches  helps  expose  their  surfaces  to  a  maximum  of  light. 


292  ]  The  Fascination  of  Flowers 

The  youngster  can  also  notice  the  way  the  plants  sometimes 
change  their  position  according  to  the  direction  of  the  source  of 
light— and  how,  when  a  new  length  of  stem  grows,  its  young  leaf 
bends  and  turns  its  stalk  to  escape,  as  much  as  possible,  the  shade 
of  surrounding  leaves.  The  leaves  of  nasturtiums,  begonias,  and 
others,  are  noticeably  adept  at  keeping  in  a  favorable  light. 

Out-of-doors  there  are  some  plants,  such  as  one  of  the  wild 
lettuces,  which  fix  their  leaves  so  consistently  in  a  north-south 
plane  that  they  are  known  as  "compass  plants." 

Some  "Dew'*  Doesn't  Fall:  Going  out-of-doors  in  the  early  morn- 
ing, a  child  always  notices  the  dew,  with  some  such  exclamation 
as,  "Look  how  much  dew  has  fallen!"  But  like  as  not  the  drops 
of  moisture  he  calls  dew,  did  not  "fall";  they  are  probably  water 
that  passed  out  of  the  grass  and  leaves  as  water  vapor  and  con- 
densed into  drops  as  it  emerged.  If  the  night  was  humid  and  cool, 
the  vapor  could  not  become  part  of  the  air  as  rapidly  as  it  came 
out  of  the  leaves. 

What  Flowers  Are  For 

There  is  much  that  a  child  can  learn  from  house  plants,  but 
the  real  fun  of  studying  flowers  is  mostly  found  outdoors.  There 
he  can  watch  insects  traveling  from  one  bloom  to  another  in  quest 
of  nectar.  As  he  observes  flowers  in  numbers,  he  will  see  countless 
interesting  variations  in  the  shapes  and  colors  of  petals  and  in 
the  forms  of  complete  flowers.  But  there  is  a  purpose  in  flowers 
beyond  mere  looks,  beautiful  though  they  are. 

A  child  may  be  old  enough  to  understand  that  what  flowers 
are  really  for  is  to  continue  the  life  of  the  plants  that  bear  them; 
yet,  looking  at  a  blooming  garden  and  with  real  curiosity  in  his 
voice,  he  will  ask,  "How  do  they?" 

How  Flowers  Develop  Seeds 

A  brief  answer  is  that  flowers  produce  seeds.  But  before 
a  flower  can  produce  seeds,  it  must  receive  grains  of  pollen  that 
will  fertilize  it.  What  is  involved  in  the  fertilization  of  a  flower? 
To  answer  this  question,  we  must  be  familiar  with  the  different 
parts  that  make  up  a  flower.

A  SEED-PRODUCING  FACTORY 

All  seeds  are  produced  by  flowers,  but  there  is  considerable  variation  in  the  forms 
of  flowers.  Not  all  types  have  both  male  parts  (stamens)  and  female  (pistil) 
within  one  blossom.  Those  that  do  are  termed  "perfect"  flowers.  This  diagram  of  a 
lily  (shown  with  transparent  petals  and  sepals)  illustrates  one  of  them. 

Here  a  difficulty  arises:  Not  all  flowers  conform  to  the  same 
pattern.  Suppose,  then,  we  consider  the  simplest  types.  One  of 
these  is  the  "perfect"  flower— such  as  the  lily— which  has  a  pollen- 
bearing  stamen  and  an  ovary  in  which  seeds  develop. 

The  other  simple  type  is  a  plant  which  bears  two  different 
types  of  flowers— the  pussy  willow  is  an  example;  one  flower  bears 
only  the  pollen-laden  stamens  while  the  other  flower  bears  the 
ovary.  In  this  case,  we  might  call  the  flower  with  the  stamens 


294] 


The  Fascination  of  Flowers 


the  "male"  flower^  while  the  flower  with  the  ovary  is  the  "female" 
flower. 

The  Parts  of  a  Flower  and  What  They  Do:  It  is  a  great  help,  in 
understanding  how  a  flower  functions,  for  a  child  to  look  at  a 
diagram  in  which  flower  parts  are  pointed  out.  If  he  has  a  diagram 
illustrating  a  perfect  flower  (as  shown  here),  he  will  find: 

The  ovary— 3.  well-protected  structure  in  the  center  of  the 
flower.  In  it  are 

The  ovules— which  contain  egg  cells,  destined  to  become  seeds. 
(Some  ovaries  contain  a  single  ovule;  others  have  many  ovules.) 
The  ovary  has  a  rather  slender  stalk,  extending  upward,  and 
known  as 

The  style.  At  its  top,  the  style  expands  into  a  broadened  tip  with 
a  sticky  surface— a  perfect  trap  for  pollen.  This  expanded  tip 
we  call 


PETALS  ARE  A   FLOWER'S   CROWNING   GLORY 

The  corolla  (meaning  ''crown")  of  a  flower  may  vary  in  countless  ways.  It  Is  made 
up  of  petals,  and  these  have  numerous  colors  and  shapes.  Sometimes,  too,  each 
petal  is  separate  (as  in  the  lily,  left);  sometimes  they  are  joined  and  show 
only  as  separate  points  (as  in  the  squash  flower,  center);  and  sometimes  (as  in 
the  petunia,  right)  there  is  no  separation  whatever. 


The  Fascination  of  Flowers  [  295 

The  stigma.  The  combined  stigma,  style,  and  ovary  form  a 
complete  pistil. 

Also  within  the  flower  are 

The  stamens.  A  stamen  consists  of 

The  filament.  This  is  a  slender  stalk,  on  the  top  of  which  rests 

The  anther  J  which  encloses  a  powder  (nearly  always  yellow) 
that  we  know  as 

The  pollen.  The  pollen  grains  are  formed  by  the  division  of 
cells  within  the  anther.  In  our  typical  flower  the  pistil  and  the 
stamens  are  surrounded  by 

The  corolla,  composed  of  petals.  This  word,  meaning  "crown," 
IS  well  chosen,  for  the  corolla  is  the  most  beautiful  part  of  the 
flower.  In  many  flowers  it  is  made  up  of  separate  petals;  in  other 
flowers— the  squash  flower,  for  one— the  petals  are  joined  together 
and  show  only  as  separate  points.  Then  there  are  still  other 
flowers— the  petunia  and  morning-glory  are  among  them— which 
have  a  corolla  all  in  one  piece,  without  any  separation  of  the 
petals.  In  any  event,  the  petals  are  encircled  by 

The  sepals.  All  together,  the  sepals  make  up 

The  calyx,  which  serves  to  protect  the  flower,  especially  in  its 
budding  stage.  The  sepals,  which  are  really  specialized  leaves, 
vary  in  size,  shape,  and  number  in  different  kinds  of  flowers. 
Often  the  sepals  are  green,  as  on  the  rose;  but  sometimes— as  in 
the  case  of  the  tulip— you  find  them  the  same  color  as  the  petals. 
On  some  kinds  of  plants  sepals  fall  off  as  soon  as  the  flower  opens; 
on  many  others— roses  and  apple  blossoms,  for  example— these 
leaves  remain  even  after  the  seeds  have  ripened. 

How  THE  Seed  Starts 

The  first  step  in  the  development  of  a  seed  is  for  pollen 
to  reach  the  flower's  stigma.  The  pollen  may  be  blown  into  the 
stigma  from  the  anther  of  some  flower.  What  happens  more 
commonly  is  that  an  insect,  going  from  one  flower  to  another  in 
search  of  nectar,  gets  pollen  on  its  body  and  the  grains  later  rub 
off  on  a  stigma. 

Once  a  pollen  grain  has  become  attached  to  the  sticky  surface 
of  the  stigma,  it  quickly  forms  a  tiny  tube  much  like  a  root  hair. 


296  ]  The  Fascination  of  Flowers 

This  tube  forces  its  way  down  the  style  to  reach  an  ^gg  cell  in  the 
ovule.  As  soon  as  the  tube  makes  its  connection  with  the  ^^g  cell, 
the  life-germ  in  the  pollen  slips  through  the  tube  to  combine  with 
the  life-germ  in  the  c^g  cell.  Thus  the  seed  starts,  developing  on 
food  furnished  by  the  plant  and  on  warmth  given  by  the  sun. 

How  THE  Seed  Is  Nourished  and  Protected 

A  fully  developed  seed  is  the  embryo  of  a  new  plant,  with 
food  stored  around  it  in  a  form  that  can  be  used  whenever  new 
growth  begins.  One  of  the  amazing  things  about  seeds  is  that 
the  stored  food  remains  usable  even  though  new  growth  does  not 
start  for  weeks,  months,  or  even  years!  (This  dormant  period 
varies,  of  course,  with  different  kinds  of  seeds.)  The  embryo  and 
the  food  supply  are  protected  by  one  or  more  layers  of  the  ovule. 

Nuts  and  Tomatoes  Are  "Fruit":  In  some  seeds,  such  as  peas  and 
beans,  the  food  supply  is  stored  within  certain  parts  of  the  embryo 
itself.  In  other  plants,  corn  and  wheat  for  example,  the  food  is 
stored  around,  rather  than  in,  the  embryo.  And  still  other  plants 
develop  elaborate  structures  about  their  seeds.  These  structures 
are  called  "fruit"— apples  and  pears  are  familiar  examples.  When 
a  scientist  speaks  of  a  "fruit,"  he  may  be  referring  to  the  ripened 
ovary  of  any  kind  of  plant,  be  it  the  pod  of  a  pea,  a  hard  nut,  01 
a  juicy  tomato. 

There  are  many  opportunities  for  examining  seeds— for  example, 
when  you  are  preparing  dinner.  To  a  hungry  diner,  peas,  beans, 
and  corn  are  food;  to  a  nature  explorer,  they  are  seeds!  A  child 
is  thrilled  to  see  the  first  sprouting  of  the  plant  embryo  after  he 
plants  a  few  seeds  in  a  glass  with  moist  soil.  If  the  seeds  are  placed 
just  inside  the  glass,  they  can  be  seen  sprouting. 

How  Flowers  Attract  Insects 

When  a  child  learns  that  pollen  is  transferred  from  one 
plant  to  another  by  messenger  insects,  he  may  wonder  what  at- 
tracts an  insect  to  flowers— is  it  their  sweet  scent  or  the  color  of 
their  petals?  This  is  the  kind  of  problem  that  scientists  still  ponder 
and  sometimes  debate  about.  For  many  years  it  was  a  generally 


The  Fascination  of  Flowers  [  297 

accepted  "fact"  that  the  chief  value  of  color  in  flowers  was  to 
attract  insects. 

Scent  Is  the  Attraction:  Along  came  a  scientist  who  had  made  a 
study  of  the  insects'  pollinizing  role.  He  pointed  out  that  bees 
and  other  flower-visiting  insects  have  poor  vision  but  a  well- 
developed  sense  of  smell.  He  also  demonstrated  that  in  addition 
to  the  colors  that  we  can  see,  some  flowers  emit  ultraviolet  rays. 
Though  these  rays  are  not  visible  to  our  eyes,  insects  can  see 
the  rays  as  well  as,  or  even  better  than,  the  colors  which  our  eyes 
perceive.  His  over-all  conclusion  was  that  color  is,  at  most,  only 
incidentally  responsible  for  bringing  insects  to  flowers. 

Since  that  time,  countless  observations  and  experiments  have 
shown  that  insects  are  attracted  by  the  scent  of  flowers.  In  the 
course  of  one  of  his  famous  experiments,  for  example,  Luther 
Burbank  worked  patiently  to  develop  a  petunia  that  would  have 
fragrance.  He  knew  that  he  had  succeeded  at  last  when  he  saw 
several  bees  hovering  over  one  of  the  plants  in  a  large  bed  of  his 
experimental  petunias.  He  quickly  verified  the  fact  that  this 
particular  plant's  flowers  were  perfumed. 

How  Pollen  Is  Carried  from  Plant  to  Plant 

It  is  vital  for  insects  to  visit  flowers  for,  as  we  have  seen, 
they  carry  pollen  from  plant  to  plant  and  thus  help  bring  about 
the  fertilization  of  flowers.  Corn  and  all  other  plants  known  as 
"grasses,"  and  most  cone-bearing  plants— such  as  pine  trees- 
depend  on  the  wind  to  convey  their  pollen. 

Breeding  Flowers:  But  sometimes  man  takes  a  hand  in  pollinating 
plants,  especially  when  he  wishes  to  create  a  hybrid,  for  a  variety 
of  reasons,  by  "crossing"  the  pollen  of  two  different  species  in  the 
same  family.  This  may  be  done  to  increase  the  hardiness  of  a 
beautiful  but  fragile  plant,  or  to  make  the  colors  of  flowers  more 
vivid. 

Crossing  different  kinds  of  plants  calls  to  mind  the  name  of 
Luther  Burbank.  He  will  undoubtedly  be  remembered  for  all 
time  as  the  great  genius  among  plant  breeders;  it  was  he  who  made 
the  science  of  "training  plants  to  work  for  man"  really  practical. 


2g8  ]  The  Fascination  of  Flowers 

He  made  countless  improvements  in  vegetables  as  well  as 
in  flowers;  bigger  and  better  potatoes,  sweet  corn  that  matures 
early  in  the  season,  luscious  blackberries  on  thornless  bushes,  and 
freestone  plums  of  excellent  flavor  and  texture,  are  just  a  few  of 
them.  There  is  no  secret  about  the  methods  he  used  to  bring  about 
his  "miracles"  with  plants.  These  methods  have  often  been  de- 
scribed, and  a  book  by  Mr.  Burbank  (Partner  of  Nature)  telling 
about  his  work  is  exciting  reading. 

How  Seeds  Are  Scattered 

One  of  the  most  intriguing  aspects  of  the  flower  story  in- 
volves the  ways  in  which  seeds  are  scattered.  Many  children  get 
their  first  notion  of  seed  dispersal  when  they  blow  at  a  dandelion 
"gone  to  seed."  Each  seed,  attached  to  a  filmy  parachute,  flies  away. 

Other  times,  say  after  a  country  hike,  a  youngster  may  find  his 
clothes  (or  his  dog's  fur  coat)  covered  with  sticktights  or  cockle- 
burs  seeking  transportation  with  their  sharp  little  hooks.  If  he 
realizes  these  "burs"  are  seeds,  unconsciously  trying  to  use  him 
or  the  dog  as  a  means  of  reaching  new  growing  grounds,  he  may 
find  the  job  of  prying  them  loose  less  tedious. 

Other  Ways  That  Seeds  Travel:  Although  the  seeds  that  are  dis- 
persed by  the  wind  are  the  most  conspicuous  ones,  we  can  observe 
other  ways  they  travel.  Some  plants,  including  violets,  pansies,  and 
touch-me-nots,  shoot  their  seeds.  Water  lilies  and  several  other 
water  plants  bear  seeds  that  manage  to  float  to  some  desirable 
growing  spot  without  becoming  water-soaked. 

180.000  Seeds  from  a  Plant:  Countless  seeds  are  unsuccessful,  as  a 
youngster  may  realize  when  he  throws  the  burs  into  a  scrapbasket; 
but  this  is  of  little  importance  as  the  number  of  seeds  borne  by 
each  plant  is  incredibly  large.  Charles  Darwin  reported  counting 
the  seeds  of  an  orchid;  he  found  more  than  six  thousand  in  a  pod. 
As  there  were  thirty  pods  on  the  plant,  the  total  number  of  pros- 
pective  seedlings   from   this  parent   would   be    something   like

A  Garden  of  His  Own 

The  modest  blooms  children  raise  themselves  will  easily  thrill 
them  as  much  as,  if  not  more  than,  the  most  spectacular  plants  to 
be  seen  at  a  flower  show.  Window  boxes  and  other  indoor  planting 
can  give  city  youngsters  some  of  the  joy  of  raising  plants;  but 
families  with  land  at  their  disposal  have  endless  opportunity 
for  engaging  in  one  of  the  most  solidly  satisfying  of  all  occupa- 
tions—working in  a  garden. 

An  important  point  for  you  to  bear  in  mind  is  that  a  youngster 
may  be  only  casually  interested  in  a  family  project— whereas  if 
he  is  given  a  small  plot  of  his  own,  the  chances  are  that  he  will 
tend  it  with  conscientious  zeal.  He  enjoys  having  the  power  to 
decide  what  is  to  grow  in  that  special  piece  of  earth,  he  finds  new 
delight  in  poring  over  seed  packets  and  catalogues,  and  he  is 
stimulated  by  the  challenge  of  trying  to  bring  his  plans  to  a 
successful  conclusion.  He  is  not  likely  to  ask  for  advice  or  help  but 
he  will  probably  welcome  a  little  of  each  if  it  is  offered  tactfully. 

Annuals,  Biennials,  and  Perennials 
In  planning  his  garden,  a  youngster  will  find  annuals, 
biennials,  and  perennials  from  which  to  choose.  Most  plants  that 
flower  the  same  season  they  are  sown  are  usually  included  with 
the  annuals  in  flower  books.  However,  the  true  annual  is  a  plant 
that  not  only  flowers  the  first  season,  but,  if  left  to  itself,  dies  in 
the  fall. 

Biennial  plants  may  flower  during  their  first  season,  but  more 
often  do  so  the  next  year.  Unless  they  are  given  special  treatment 
by  the  gardener  during  their  first  season,  biennials  die  after  their 
second  season. 

Perennials— with  the  exception  of  woody  types— die  down  to  the 
ground  in  the  fall.  But  the  roots  continue  to  live,  and  new  branches 
and  flower  stems  are  thrown  up  for  years. 

Trees,  Shrubs,  and  Herbs 

Another  interesting  point  for  the  young  gardener  is  that 
most  flowering  plants  belong  to  one  of  three  general  forms:  trees, 
which  have  large,  erect  stems;  shrubs,  with  stems  that  are  smaller 


300  ]  The  Fascination  of  Flowers 

and  bushy;  and  herbs,  with  stems  that  are  more  or  less  soft,  and 
with  little  woody  tissue.  We  most  commonly  use  the  term  "herb"  to 
describe  plants  valuable  for  medicinal  purposes  or  for  their 
flavor  or  sweet  scent.  Nevertheless,  the  majority  of  flowers  (domes- 
ticated as  well  as  wild),  grasses,  and  weeds  are  herbs.

Flowers  for  A  Beginner 

If  you  are  a  beginner,  there  are  several  points  you  will 
want  to  bear  in  mind.  It  is  important  to  have  plants  that  will 
thrive  with  the  amount  of  sun  that  reaches  the  plot  you  are  using. 
It  is  fun  to  have  at  least  a  few  showy  flowers— such  as  hollyhocks 
or  salvia— as  well  as  flowers  good  for  cutting.  Phlox,  dianthus 
(pinks) ,  zinnias,  and  asters  are  a  few  of  the  many  that  provide 
generous  floral  decoration  for  your  home.  Plants  should  be  ar- 
ranged so  that  those  which  grow  tall  will  be  at  the  back  of  the 
garden;  the  lowest  ones  should  be  in  front,  or  else  grown  to  form 
a  border. 

Plan  Your  Color  Scheme:  Your  child  can  begin  to  enjoy  his  garden 
well  ahead  of  the  planting  season  if  he  works  out  a  "theme"  for 
his  plot.  It  may  be  an  all-yellow  color  scheme  (marigolds,  Cali- 
fornia poppies,  nasturtiums,  calliopsis)  ;  or  purple  and  white 
(petunias,  asters,  baby's  breath,  hollyhocks)  ;  or  red  (salvia), 
white  (petunia),  and  blue  (ageratum) .  These  flowers  are  a  few 
of  the  many  annuals  from  which  a  child  should  choose  to  obtain 
an  abundance  of  blooms. 

Protect  the  Seeds:  If  seeds  are  put  in  the  earth  too  early  they 
may  freeze  or  rot.  It  is  therefore  advisable  to  start  some  annuals— 
pansies,  for  example— indoors  or  in  a  protected  seed  bed,  and  then 
move  the  young  plants  to  the  garden  when  the  weather  is  suitable. 
Many  flower  enthusiasts  eliminate  this  step  by  purchasing  plants 
from  commercial  growers.  Pansy  plants  produced  from  seeds 
planted  outdoors  do  not  bloom  until  the  end  of  summer. 


The  Fascination  of  Flowers  [301 

Pansies— Perfect  for  Children 

Youthful  gardeners  can  ask  for  no  more  delightful  flower 
than  the  pansy.  Its  coloring  is  beautiful  and  its  markings  often 
give  it  an  appealing  face.  The  dark  spots  at  the  bases  of  the  side 
petals  and  the  lines  radiating  from  them  suggest  eyes  and  eye- 
lashes, the  opening  of  the  nectar  tube  makes  a  nose,  and  the 
spot  near  the  base  of  the  lower  petal  will  pass  for  a  mouth. 

Many  varieties  of  pansies  may  be  easily  raised  from  seed  sown 
in  the  spring  or  early  summer,  and  seedlings  may  be  set  out  in 
the  garden  in  early  spring.  They  do  better  in  shady  areas  than  in 
full  sunshine. 

Pansies  Are  Ideal  for  Picking:  Children  love  to  pick  flowers. 
This  makes  the  pansy  an  ideal  plant  for  a  child,  as  the  flowers 
should  be  picked  as  soon  as  they  open,  or  shortly  afterward.  If 
the  pansy's  seeds  are  allowed  to  ripen,  the  plant  will  bloom  for 
only  a  short  time,  its  life  purpose  having  been  accomplished. 
Persistent  picking  of  the  blooms,  on  the  other  hand,  constantly 
produces  new  buds. 

How  Bees  Help  Fertilize  the  Pansy:  The  nectar  sought  by  bees 
in  the  pansy  is  contained  in  the  spur  formed  by  the  lower  petal 
extending  behind  the  flower.  As  the  insect  probes  the  nectar  well 
with  its  tongue,  pollen  from  a  flower  previously  visited  brushes 
off  against  the  stigma.  At  the  same  time  the  bee  receives  a  fresh 
coating  of  pollen  dust.  Shortly  after  a  pansy  has  been  fertilized, 
you  can  notice  the  ribbed  seed  pod  becoming  prominent.  Finally 
this  opens  in  three  valves,  and  the  seeds  are  scattered  as  the  edges 
of  each  valve  curl  inward. 

Tulips—The  National  Passion  of  Holland 

This  famous  flower  was  introduced  into  Europe  from  the 
East  in  the  sixteenth  century,  and  about  a  hundred  years  later 
became  the  national  passion  of  Holland.  The  Dutch  growers 
speculated  in  outstandingly  beautiful  varieties  of  the  tulip  as 
some  people  speculate  in  stocks!  Anyone  who  is  familiar  with 
these  lovely  flowers  will  understand  the  hold  they  took  on  Dutch 
tulip-fanciers. 


502  ]  The  Fascination  of  Flowers 

Tulips  Are  Planted  in  the  Fall:  Tulips  are  excellent  material 
for  youngsters  who  enjoy  gardening  in  every  season  of  the  year. 
They  may  be  put  in  the  earth  during  September  or  October. 
Each  bulb  is  formed  of  several  layers  of  leaves,  all  of  which  may 
open  above  ground  if  the  planting  is  done  properly— with  the 
tip  of  the  bulb  pointed  upward.  The  leaf  layers  are  fleshy,  for 
they  contain  the  food  that  was  stored  up  during  the  previous 
season.  This  food  nourishes  the  flower  bud  in  the  heart  of  each 
bulb  and  the  other  growing  parts.  The  roots,  forming  a  thick 
white  tassel  below  the  bud,  bring  minerals  and  water  up  from 
the  soil. 

The  Tulip's  Spring  Buds:  In  the  spring,  the  anxious  gardener 
first  sees  his  tulip  buds  appear,  protected  by  three  sepals.  As 
the  bud  stretches  upward  and  becomes  larger,  the  green  of  the 
sepals  changes  to  the  color  of  the  petals.  When  the  flower  finally 
opens  there  is  no  very  noticeable  difference  between  petal  and 
sepal.  The  sepals  are  below  the  petals  and  stand  out  around  them, 
giving  the  flower  a  triangular  shape.  When  the  sun  is  not  bright, 
the  sepals  partially  close  about  the  flower. 

Bachelor's-Buttons— Composite  Flowers 

Most  children  love  this  hardy  and  beautiful  plant,  often 
called  the  cornflower.  It  may  have  special  interest  for  them,  too, 
if  they  realize  it  is  one  of  the  "composite"  plants— a  group  in 
which  different  kinds  of  flowers  are  attached  to  one  head.  Those  at 
the  center  of  this  compound  flower  head  work  for  the  production 
of  seeds,  while  the  flowers  surrounding  the  center  serve  merely  to 
attract  insects. 

The  bachelor's-button  usually  has  from  seven  to  fourteen  mar- 
ginal flowers  and  they  may  be  white,  pink,  blue,  or  purple.  Each 
of  the  center  flowers  has  a  white  corolla  tube,  enlarged  toward 
the  upper  end  to  a  purple  bulb,  and  a  purplish  anther  tube  which 
is  bent  far  over  so  that  its  tip  opens  toward  the  middle  of  the 
flower  head. 


The  Fascination  of  Flowers  [  303 

Garden  Geraniums—Butterflies'  Favorite 

On  no  other  flower  will  you  see  a  more  obvious  nectar  well; 
that  of  the  geranium  extends  almost  the  whole  length  of  the 
flower  stalk.  The  long  narrow  nectar  tube  explains  why  you  often 
see  butterflies  on  geraniums;  this  shape  is  especially  suitable  for 
the  long-tongued  insects. 

Some  of  these  plants  are  called  "horseshoe"  geraniums  because 
of  the  horseshoe  pattern  on  many  of  the  leaves.  Botanically  they 
are  not  true  geraniums,  being  the  descendants  of  the  pelargonium 
—a  plant  that  was  brought  to  England  from  South  Africa  more 
than  two  hundred  years  ago.  These  African  plants  were  the  ances- 
tors of  many  of  our  popular  garden  geraniums.  Other  varieties 
have  been  bred;  Luther  Burbank,  for  example,  created  the  now 
popular  crinkled-leaf  species  from  a  single  wild  geranium  plant 
that  did  not  have  the  customary  smooth-edged  leaves. 

Seeds  Spread  by  Explosion:  Some  geraniums  have  depended  for 
so  long  on  man  for  planting  that  they  have  almost  lost  the 
power  of  producing  seed.  However,  in  the  single  blossoms  you  may 
sometimes  discover  the  ovary  changed  into  a  long  beaklike  seed 
pod— a  feature  that  reveals  its  relationship  to  the  wild  geranium. 
The  seeds  are  dispersed  by  an  explosive  action  of  the  pod. 

How  Geraniums  Open:  It  is  interesting  to  watch  geranium  flow- 
ers opening.  Several  buds  are  grouped  together  in  a  nest  of  spe- 
cialized leaves  known  as  "bracts."  Besides  having  this  protection, 
each  bud  is  individually  guarded  by  its  own  sepals.  As  the  flower 
stalk  grows  longer  and  droops  from  the  weight  of  the  buds,  the 
bracts  often  fall  off.  In  each  mass  of  drooping  buds,  the  ones  in 
the  center  open  first.  It  sometimes  happens  that  by  the  time 
those  on  the  outside  are  in  bloom  the  center  flowers  have  begun 
to  wither. 

Nasturtiums  and  Their  Remarkable  Method 
OF  Pollination 

The  most  remarkable  aspect  of  the  nasturtium  is  its  special 
method  of  pollination.  The  five  beautiful  petals  are  set  around 
the  mouth  of  the  long  tube  leading  to  the  nectar  well.  The  two 


304  ]  T^he  Fascination  of  Flowers 

upper  petals  are  erect,  suggesting  colorful  display  signs.  They  are 
marked  with  lines  that  point  toward  the  opening  of  the  nectar 
tubes.  The  lower  petals  stand  out  to  form  a  landing  platform  for 
visiting  insects. 

Despite  this,  the  flower  is  not  actually  designed  for  hospitality; 
it  can  accommodate  only  big  insects  such  as  sizable  bees  or  butter- 
flies for  its  pollination  work,  and  it  is  able  to  thwart  smaller,  use- 
less creatures  that  might  creep  into  its  treasure  house  of  nectar. 
Each  of  the  lower  ''landing"  petals  narrows  to  a  fine  strip  at  its 
inner  end,  making  it  in  effect  a  footbridge  to  the  nectar  tube. 
These  bridges  are  covered  with  projecting  fringes  and  numerous 
little  spikes  that  prove  an  effective  barrier  to  any  small  creeping 
visitors. 

Mechanized  Pollination:  When  a  nasturtium  first  opens,  its  several 
stamens  are  all  bent  downward.  But  when  the  pollen-containing 
anthers— located  at  the  end  of  each  slender  stalk  of  a  stamen 
—are  ready  to  function,  the  stalk  lifts  up  so  that  it  is  directly 
in  the  path  of  the  nectar  store.  When  a  bee  or  butterfly,  or  oc- 
casionally a  hummingbird,  touches  the  stamens,  it  is  sometimes 
bombarded  with  pollen.  Equally  remarkable  is  the  action  of  the 
anther:  No  sooner  has  it  discharged  its  pollen  than  it  shrivels, 
making  way  for  a  new  anther. 

While  all  this  is  going  on,  the  flower's  three-lobed  stigma  lies 
quietly  below  and  behind  the  anthers.  (The  stigma  is  located 
on  the  prolongation  of  the  ovary  known  as  the  style.)  But,  once 
all  the  pollen  has  been  shed,  the  stigma  rises  up  and  opens.  Now 
the  stigma  operates  like  a  three-pronged  fork,  and  as  more  insects 
come  in  quest  of  nectar,  it  rakes  pollen  from  them.  Thus  the 
ovary  is  fertilized  and  the  seeds  are  ready  to  develop. 

Petunias  and  Their  International  Background 

Profusely  blooming  petunias  are  so  much  a  part  of  our 
American  garden  scene  that  it  comes  as  a  surprise  to  us  to  learn 
that  they  have  an  international  background.  They  are  the  result 
of  a  cross  between  two  species  of  plants  from  different  parts  of 
South  America.  The  first  of  these,  with  long-tubed  white  flowers, 
was  brought  to  Europe  a  little  more  than  a  hundred  years  ago. 


The  Fascination  of  Flowers  [  305 

Shortly  afterward  seeds  of  the  second  species,  having  small,  broad- 
tubed,  red-purple  flowers,  were  sent  to  the  Glasgow  Botanical 
Gardens  where  the  two  species  were  brought  together.  Today  we 
find  petunias  of  many  colors,  but  red-purple  and  white  still  pre- 
dominate. 

Pollen  for  Petunias:  The  petunia's  wonderful  arrangement  for 
pollination  is  one  of  the  marvels  of  nature.  Near  the  bottom  of 
the  long  tube  lies  the  stigma,  with  two  well-developed  anthers 
in  front  of  it  and  two  more— not  quite  so  advanced— behind  it. 
The  stalks  that  support  the  front  anthers  are  longer  than  those 
of  the  second  pair.  There  is  still  another  anther— a  fifth— on  a 
stalk  shorter  than  all  the  others.  This  is  apparently  a  little  pollen 
supply  held  in  reserve  by  the  flower. 

For  about  half  its  length,  each  stamen  is  attached  to  the  base 
of  the  flower's  tube.  The  rest  of  the  stamen  curves  abruptly  in- 
ward. This  makes  it  snuggle  up  to  the  pistil,  the  base  of  which 
is  set  in  the  nectar  well  at  the  bottom  of  the  flower.  When  an  in- 
sect pays  a  visit,  its  tongue  reaches  along  the  flower  tube  toward 
the  nectar  and  it  presses  against  the  stamens  at  the  point  where 
they  curve.  This  causes  the  anthers  to  move  about,  and  as  they 
move  their  pollen  is  shaken  off  on  the  insect! 

In  an  older  petunia  the  stigma,  standing  above  the  empty 
anthers,  opens  into  two  lobes  and  is  ready  to  receive  pollen  from 
other  flowers. 

The  Petunia  and  the  Hummingbird  Moth:  The  most  notable  in- 
sect partners  of  petunias  are  the  sphinx  or  hummingbird  moths, 
which  can  often  be  seen  hovering  over  these  flowers  in  the  early 
evening.  Petunias  are  members  of  the  "nightshade"  family,  which 
also  includes  the  tomato,  the  potato,  and  tobacco.  Hummingbird 
moths  are  distinctly  partial  to  all  these  plants. 

Poppies—They  Fascinate  Bees 

The  poppy  is  distinctly  a  bee's  flower.  The  insects  ap- 
parently delight  in  wallowing  in  the  pollen  that  lies  along  the 
ridges  of  the  flower's  pistil. 

This  pistil  resembles  a  tiny  vase  with  a  circular  cover.  After 


3o6  ]  The  Fascination  of  Flowers 

a  poppy  has  been  fertilized,  the  circular  cover  develops  a  scalloped 
edge.  Sharp  ridges  run  from  the  center  of  each  scallop  down  the 
length  of  the  vaselike  pistil.  These  ridges  are  the  outer  edges  of 
partitions.  Countless  seeds  develop  inside  these  partitions  and, 
when  ripe,  they  fall  into  the  hollow  capsule  which  forms  the 
center  of  the  pistil. 

The  Poppy's  Seed-Shaker:  An  observant  child  is  charmed  to  see 
how  poppy  seeds  make  their  way  in  the  world.  As  each  segment 
of  the  capsule  loosens  at  the  top  and  curls  back  from  the  circular 
cover,  openings  are  formed.  The  upshot  is  that  the  *Vase"  has 
been  made  into  a  perfect  seed-shaker.  When  the  wind  blows  on 
it,  or  when  it  is  brushed  by  any  passing  creature,  the  contents— 
the  seeds— are  sprinkled  a  little  at  a  time  in  all  directions. 

There  are  a  great  many  varieties  of  poppies,  but  only  four 
species  are  commonly  cultivated:  the  corn  poppy  and  the  opium 
(both  of  them  annuals);  the  arctic  and  the  oriental  (both 
perennials) . 

The  California  poppy  in  its  native  setting  blooms  abundantly 
from  February  to  April  in  the  desert  and  the  foothills.  In  gardens 
in  the  East  you  can  see  the  shining  orange  flowers  from  mid- 
summer until  frost  arrives. 

Irises— Large  and  Showy 

The  large,  showy  iris,  also  called  "blue  flag,"  is  another 
plant  favored  by  bees.  It  has  an  interesting  shape  because  of  its 
unique  style,  which  is  divided  into  three  branches  so  large  and 
broad  that  they  appear  to  be  petals.  These  branches  combined 
with  the  sepals  form  a  tunnel  through  which  bees  pass.  Between 
the  sepals  and  the  style  are  the  true  petals,  marked  with  decora- 
tive purple  lines. 

How  the  Bee  Maneuvers  on  the  Iris:  The  bee  uses  the  lip  of  a 
sepal  for  its  landing  platform,  then  pushes  forward  through  the 
tunnel  to  the  nectar  well.  As  the  insect  moves,  pollen  that  it  has 
collected  from  another  flower  is  rubbed  off  against  the  stigma, 
which  hangs  like  a  tent  flap  above  the  nectar  well.  The  stigma  is 
so  fashioned  that  it  gathers  pollen  from  an  incoming  insect  but 
turns  a  blank  side  to  the  departing  visitor. 


The  Fascination  of  Flowers  [  307 

The  small  solitary  bees  are  persistent  callers;  so  are  bumblebees 
and  honeybees,  though  they  seem  to  prefer  different  varieties  of  the 
iris. 

Roses—The  World's  Most  Popular  Flowers 

It  has  been  said  that  children  see  so  many  roses  that  they 
take  them  for  granted.  I  doubt  that  this  is  really  their  attitude, 
as  so  many  of  them  choose  roses  when  asked  to  write  aboutjJifiir 
favorite  nature  subject.  Certainly  the  rose  appears  to  be  the 
world's  most  popular  flower.  It  is  grown  wherever  gardening 
is  practiced,  in  all  temperate  climates  and  in  some  tropical  regions 
as  well.  It  is  also  believed  to  be  the  oldest  of  cultivated  flowers. 

Though  no  flower  is  more  readily  identified,  many  people  are 
perplexed  by  the  question,  "What  is  a  rose?"  Looking  for  an 
answer,  we  may  be  inclined  to  find  more  sense  than  nonsense 
in  Gertrude  Stein's  famous  statement,  "A  rose  is  a  rose  is  9 
rose";  for  the  rose  has  endless  varieties  and  it  is  neither  an  ordinary 
seed  plant  nor  a  tree.  There  are  single  blooms,  having  only  one 
row  of  showy  petals,  and  double  blooms  with  their  rows  of  petals 
arranged  in  regular  sequence  or  in  loose  informal  patterns. 

Five  Thousand  Varieties  of  Roses:  The  roses*  bright  colors  cover 
a  wide  range  from  white,  through  delicate  pink,  yellow  to  rich 
tones  of  red.  As  to  size,  they  vary  from  dime-small  miniatures  to 
exhibition  blooms  seven  inches  and  more  across.  Believe  it  or 
not,  in  the  United  States  alone  there  are  more  than  five  thousand 
varieties,  each  differing  in  some  detail.  The  plant  is  a  woody 
shrub  which  may  stand  erect  or  climb  on  supports.  It  has  an 
extensive  root  system  that  sometimes  goes  as  deep  as  twenty  feet 
into  the  ground. 

Roses  and  Strawberries  Are  Relatives:  Aside  from  the  innumer- 
able kinds  of  roses  produced  in  gardens,  there  is  the  simple  but 
very  beautiful  wild  rose  with  its  broad  blossoms  that  display 
five  pink  petals.  On  a  wild  rose  or  a  full-blown  garden  rose  you 
can  easily  see  the  great  number  of  stamens,  about  twenty,  as  a 
rule,  a  characteristic  feature  of  the  whole  family.  Usually  there 
are  a  great  many  pistils  also. 


3o8  ]  The  Fascination  of  Flowers 

Many  of  our  common  fruits  belong  to  the  rose  family;  the 
plants  include  the  creeping  strawberry  as  well  as  the  sturdy  black- 
berry bush  and  apple  tree.  Though  these  plants  differ  considerably 
in  size  and  general  appearance,  their  blossoms  have  a  great 
similarity  to  the  rose. 

Chrysanthemums—Japanese  Favorite 

The  chrysanthemum  has  a  double  flower  head,  numerous 
petals,  and  lovely  coloring  (generally  red,  yellow,  and  white) . 
It  gets  wide  publicity  every  fall  as  the  star  attraction  of  countless 
flower  shows.  But  it  is  not  only  the  spectacular  prize-winning 
varieties  that  merit  popularity.  There  are  many  kinds  that  will 
flourish  without  highly  skilled  care,  bringing  fresh  beauty  to  our 
gardens  in  the  fall  when  most  flowers  are  dying. 

Until  fairly  recently  "mums"  could  be  grown  in  northern 
climates  only  inside  a  greenhouse;  but  now  we  have  hardy  types 
that  bloom  out-of-doors  through  light  frost.  These  perennials 
usually  survive  the  winter,  and  each  spring  you  can  separate  the 
new  growths  and  replant  them.  Thus  your  chrysanthemum  dis- 
play can  expand  considerably  from  a  very  few  plants. 

Two  Thousand  Years  of  Chrysanthemums:  Two  thousand  years 
ago,  a  chrysanthemum  much  like  a  colored  daisy  was  a  popular 
garden  flower  in  Japan.  (A  figure  of  a  sixteen-petaled  chrysanthe- 
mum is  used  as  the  crest  of  the  Japanese  imperial  family.)  Early  in 
the  eighteenth  century  some  of  these  flowers  were  brought  to 
England,  and  China  and  India  contributed  other  species.  English 
gardeners  and  plant  breeders  went  to  work  with  them  and  in  less 
than  a  hundred  years  produced  new  varieties  bearing  flowers 
three  times  as  large  as  any  of  the  originals. 

Dahlias— They  Grow  Even  on  Ash  Heaps 

The  dahlia,  a  reddish  flower  that  originated  in  Mexico 
and  Central  America,  is  a  popular  show  flower.  Because  of  their 
size  and  beauty,  you  might  suspect  that  dahlias  are  difficult  to  raise. 
The  fact  is,  though,  that  dahlias  are  adaptable  to  almost  any  kind 
of  soil,  if  it  has  been  properly  prepared. 


The  Fascination  of  Flowers  [  309 

Clayey  soil  may  be  lightened  with  coal  ashes  or  sand,  plus 
vegetable  matter  and  manure.  A  light  sandy  loam  will  produce 
healthy  plants  and  exquisite  blooms;  gravelly  fields  have  been 
known  to  support  fine  dahlia  beds;  and  a  plant  may  even  be 
found  growing  in  an  ash  heap  where  a  tuber  (the  underground 
stem)  has  been  discarded. 

How  to  Protect  Dahlia  Seeds:  You  can  raise  dahlias  from  stem 
cuttings  as  well  as  from  tubers.  For  a  real  gardening  adventure, 
your  youngster  may  enjoy  trying  to  develop  new  dahlias  from 
seeds.  The  project  begins  at  the  height  of  the  blooming  season, 
when  he  must  be  on  the  lookout  for  any  particularly  large,  rich- 
colored  flower.  This  should  be  tagged  'Tor  Seed,"  so  that  it  will 
not  be  picked. 

The  chosen  flower  must  now  remain  in  the  garden  until  insects 
have  carried  pollen  to  it  and  it  "goes  to  seed."  When  the  flower 
shrivels  and  turns  brown,  you  tie  a  small  paper  bag  over  it  so  that 
you  can  save  the  seeds  if  the  seed  pod  bursts. 

How  to  Plant  Dahlia  Seeds:  Late  fall  is  the  time  for  you  to  gather 
the. seeds,  drying  them  and  storing  them  in  an  airtight  bottle. 
Early  in  May  you  plant  them  in  a  box  with  one  part  soil  to  two 
parts  sand  mixture.  When  seedlings  appear  about  two  weeks 
later,  transplant  them  to  a  sunny  spot  in  the  garden. 

Until  the  buds  finally  open,  the  young  gardener  will  go  through 
the  suspense  of  wondering  whether  they  will  be  double  or  single 
flowers  and  what  their  color  will  be.  It  all  depends  on  what  pollen 
was  carried  to  his  flowers  during  the  previous  season. 

Indoor  Gardening 

If  you  live  in  an  apartment  and  cannot  have  a  garden 
outdoors,  you  and  your  child  can  share  the  rich  pleasures  of 
starting  a  garden  indoors.  Bulbs  are  especially  suitable.  (Bulbs 
are  buds  made  up  of  a  stem  surrounded  by  leaves.)  You  can  buy 
them  inexpensively  at  many  department  stores,  hardware  stores, 
or  florist  shops. 

Narcissus  Bulbs  Are  Easy  to  Grow:  The  narcissus,  a  popular  favor- 
ite with  yellow  or  white  varieties,  need  only,  be  supported  in  a 


g  lo  ]  The  Fascination  of  Flowers 

shallow  dish  with  pebbles  or  bits  of  broken  shell,  and  given  just 
enough  water  to  show  through  the  pebbles. 

Unaided,  a  youngster  can  easily  prepare  a  dish  for  a  narcissus 
bulb,  and  will  be  thrilled  at  having  something  his  very  own.  To 
enhance  his  enjoyment,  a  narcissus  grows  rapidly  and  thus  re- 
wards daily  watching.  Care  should  be  taken  when  watering  that 
water  does  not  leak  in  where  old  leaves  have  broken  off,  as  this 
causes  a  bulb  to  rot. 

..  When  it  is  first  planted,  the  bulb  should  be  kept  in  a  dark 
cool  place  until  its  roots  have  formed.  Outdoors  this  would  take 
from  eight  to  twelve  weeks,  but  indoors  only  a  few  weeks  are 
required.  The  plant  should  then  be  brought  into  sunlight  gradual- 
ly, being  kept  away  from  drafts.  Two  or  three  weeks  will  elapse 
before  a  flower  appears. 

Hyacinth,  Tulip,  and  Crocus  Bulbs:  Such  bulbs  as  hyacinths  and 
tulips  do  better  in  soil.  As  bulbs  have  a  built-in  food  supply,  the 
soil  need  not  be  rich.  Sandy  garden  soil  well  mixed  with  {>eat 
moss  is  excellent.  A  hyacinth  bulb  should  be  placed  so  that  its 
top  projects  over  the  top  of  the  pot;  a  tulip  bulb  should  have 
its  top  level  with  the  top  of  the  soil.  As  for  crocus  and  other  small 
bulbs,  they  should  be  covered  with  an  inch  of  soil. 

If  you  keep  the  bulbs  in  a  cool  dark  place  for  several  weeks, 
the  roots  will  be  well  developed  before  the  leaf  stalks  begin  to 
grow.  When  the  roots  press  against  the  sides  of  the  pot  or  show 
at  the  bottom  opening,  you  know  that  the  plants  are  ready 
for  a  sunny  window. 

Other  Easy  Indoor  Gardening  Techniques 
You  need  not  limit  your  indoor  gardening  to  bulbs.  You 
have  the  choice  of  plants  growing  directly  from  roots,  such  as  the 
sweet  potato;  from  stem  cuttings— begonia,  geranium,  or  cactus, 
among  others;  and  from  certain  fleshy  leaves,  such  as  those  of 
the  African  violet.  Also,  many  seeds  thrive  when  they  are  planted 
indoors. 

A  wooden  cigar  box  will  do  to  give  stem  cuttings  or  leaves 
their  start.  Bore  holes  in  the  bottom  and  spread  pebbles  or  chips 
from  broken  flowerpots.  Then  fill  the  box  with  clean  sand  to  with- 


The  Fascination  of  Flowers  [311 

in  half  an  inch  of  the  top.  Moisten  the  sand  and  press  it  down 
firmly.  Make  a  hole  in  this  soil  for  each  stem  cutting  you  wish 
to  plant.  (A  pencil  is  a  very  good  tool  for  this  purpose.) 

Now  place  a  freshly  cut  stem  in  each  hole,  making  sure  that  in 
every  case  you  have  buried  at  least  two  ''nodes"  —  juncture  points 
for  leaves  that  have  been  removed.  Keep  the  little  garden  moist,  in 
a  cool  place,  and  before  long,  roots  should  form  at  each  node. 

How  to  Propagate  Plants 

African  Violets 

You  can  work  out  an  excellent  arrangement  for  propagat- 
ing African  violets  from  leaves  by  using  two  flowerpots— one  an 
eight-inch  size  and  shallow,  the  other  a  three-inch  pot.  Cover  the 
hole  of  the  larger  pot  with  a  piece  of  crockery  and  partly  fill  the 
pot  with  sand.  Close  the  hole  of  the  smaller  pot  with  a  cork,  and 
place  this  pot  inside  the  larger  one,  filling  the  space  between  the 
two  pots  with  more  sand.  If  you  keep  the  small  flowerpot  filled 
with  water,  the  sand  will  be  moist  at  all  times.  Set  the  base  ol 
the  violet  leaves  in  the  moistened  sand. 

Begonias  and  Snake  Plants 

Begonia  leaves  may  simply  be  pegged  down  with  toothpicks 
on  moist  sand  and  slit  across  the  main  veins.  Small  plants  will 
develop  at  the  wounds.  The  ever-popular  snake  plant,  or  Sanse- 
vieria,  may  be  propagated  by  cutting  leaves  into  sections  an  inch 
or  more  in  length  and  pegging  them  into  moist  earth.  The  leaves 
of  this  white  or  yellowish  plant  take  root  easily  but  grow  slowly. 
Any  plant  you  are  raising  from  leaves  or  stems  should  be 
covered  by  a  glass  jar  or  globe  until  it  has  become  well  rooted. 
The  covering  keeps  the  air  immediately  surrounding  the  plants 
moist;  an  excessively  dry  atmosphere  would  soon  kill  them. 

Growing  Flowers  Indoors 

If  flowers  interest  you  more,  you  will  find  that  marigolds, 
petunias,  and  other  plants  will  flourish  in  your  window  boxes. 
Smaller  seeds  should  be  planted  about  a  quarter  of  an  inch  deep. 


gig]  The  Fascination  of  Flowers 

and  larger  ones  slightly  deeper;  allow  at  least  an  inch  between 
seeds.  When  your  seedlings  are  large  enough  to  handle,  transplant 
them  to  window  boxes  or  flowerpots.  An  excellent  mixture  in 
which  to  plant  them  at  this  time  combines  two  parts  garden  soil, 
one  part  sand,  and  one  part  leaf  mold. 

Vegetables— for  Decoration  and  Food 

Sweet  Potatoes 

Of  all  the  plants  that  can  be  raised  from  roots,  the  sweet 
potato  is  probably  the  most  satisfying.  It  needs  nothing  but  water. 
A  sweet  potato  should  be  placed  in  a  glass  or  bowl  so  that  about 
one-third  of  it  is  in  water.  If  necessary,  you  can  push  three  tooth- 
picks into  the  plant  to  support  it  on  the  rim  of  the  bowl  or 
glass.  Although  this  will  not  yield  a  vegetable  harvest,  the  leaves 
produced  are  extremely  decorative. 

Working  with  Seeds 

If  you  wish  to  work  with  seeds,  you  will  need  a  shallow 
tray  with  holes  in  the  bottom  (for  drainage)  to  start  your  garden- 
ing. Place  small  stones  or  pieces  of  broken  flowerpots  over  the 
holes;  then  sift  soil  into  the  box  and  press  down  firmly  until  the 
soil  is  within  an  inch  of  the  top.  If  you  want  to  try  a  miniature 
vegetable  garden,  you  can  plant  such  seeds  as  peas,  beans,  and 
radishes. 

Growing  Dandelion  Greens 

A  child  who  shows  real  enthusiasm  for  gardening  may 
derive  great  pleasure  from  growing  a  few  indoor  "crops"  during 
the  winter  which  may  be  used  on  family  menus.  However,  a  warm 
cellar  is  usually  essential  for  such  activity.  There  are  several 
plants  that  will  flourish  in  a  box  of  earth  set  beside  a  furnace. 
Dandelion  greens,  which  are  a  tasty  substitute  for  lettuce,  are 
among  the  easiest  to  obtain  and  raise. 

Dig  up  the  plants,  including  roots,  before  the  ground  freezes, 
and  cut  off  a  good  two  inches  of  the  leafy  top.  Then  set  the 
roots  in  a  box  of  good  garden  soil,  and  keep  them  in  a  constantly 


The  Fascination  of  Flowers  [313 

warm  location— if  possible,  near  a  furnace.  They  require  some 
watering  but  need  no  light. 

Growing  Rhubarb 

Rhubarb  will  thrive  under  cooler  conditions.  A  tempera- 
ture of  about  50  degrees  is  best;  but  the  atmosphere  should  be 
moist  and  the  plants  should  not  be  in  a  draft.  To  provide  an  oc- 
casional winter  pie  or  breakfast  fruit,  dig  up  clumps  of  rhubarb 
root  in  November;  you  can  allow  them  to  freeze  under  natural 
conditions  or  in  a  freezer.  Then  store  them  in  a  cool  place 
and  plant  portions  from  time  to  time  in  a  box  of  earth  or  sand. 
Tender  young  shoots  will  grow  from  the  nourishment  stored  up 
in  the  roots. 

Young  Dirt  Farmers 

There  is  something  about  working  with  earth  that  is  deeply 
satisfying  to  boys  and  girls— and  out-of-door  vegetable  gardening 
provides  a  splendid  combination  of  physical  exercise  plus  the 
challenge  of  producing  food  from  the  soil. 

When  space  is  limited,  we  sometimes  feel  it  is  best  to  "bother" 
only  with  flowers.  However,  a  small  corner  devoted  to  vegetables 
can  give  youngsters  a  wonderful  sense  of  accomplishment.  I  know 
of  two  ten-year-old  boys  who  raised  radishes,  lettuce,  corn,  string 
beans,  tomatoes,  beets,  and  carrots  in  one  plot  just  six  by  ten 
feet.  They  were  able  to  make  substantial  contributions  to  the  table, 
and  the  only  help  their  parents  gave  was  in  the  spading. 

Radishes— A  Fast  Crop 

Radishes  are  a  special  boon  to  young  gardeners— particu- 
larly those  with  limited  planting  space.  Some  radish  seeds  may  be 
mixed  in  with  seeds  of  other  vegetables,  perhaps  beets  and  carrots, 
for  they  pop  up  above  ground  in  a  few  days.  Thus  the  planted 
rows  are  almost  immediately  marked,  and  weeds  cropping  up  be- 
tween them  can  be  dealt  with  promptly.  Another  good  point 
about  radishes  is  that  they  mature  in  a  month  or  so  and  can 
then  be  pulled  out  and  eaten— while  the  slower-growing  vegetables 
continue  to  develop  and  occupy  space  vacated  by  the  radishes.

Corn— A  Somewhat  Puzzling  Plant 

Even  children  who  do  not  aspire  to  raise  their  own 
vegetables  are  likely  to  be  interested  in  growing  corn.  Corn  is 
a  universal  food  favorite.  Not  only  that— it  is  something  of  a 
symbol  of  our  American  heritage— of  lessons  learned  from  the 
Indians  and  the  bountiful  harvest  that  inspired  our  traditional 
Thanksgiving. 

Corn  is  in  a  class  by  itself  and  something  of  a  puzzle.  What  is 
the  silk  tassel  comparable  to  on  other  plants?  Are  those  green 
husks  that  encase  each  ear  regular  leaves?  How  do  the  green 
husks  differ  from  the  long  narrow  leaves  that  hang  loosely  from 
the  stalk?  Is  each  kernel  of  corn  a  seed,  or  is  the  whole  cob  a  seed? 
And  why  do  we  sometimes  find  tiny,  undeveloped  kernels  among 
others  that  are  fully  ripe? 

Early  Development  of  the  Corn  Plant:  If  a  child  could  observe 
the  progress  of  a  corn  plant,  he  would  see  that  when  it  first  ap- 
pears above  the  ground,  its  leaves  are  wrapped  in  a  colorless  sheath 
in  a  pointed  roll.  These  leaves  soon  spread  apart.  Growth  is  slow; 
but  presently  the  main  stalk  becomes  visible— and  once  above  the 
ground,  it  stretches  up  rapidly. 

The  main  stalk  develops  more  leaves  and  also  ears  which  are 
located  at  the  leaf  joints,  or  nodes,  where  the  stalk  is  hollowed  out 
in  order  to  hold  the  ear  more  snugly.  The  ear  is  actually  on  a 
branch  stalk,  and  the  leaves  of  this  stalk  are  those  that  are 
wrapped  around  the  portion  we  call  the  "cob."  It  is  on  the  cob 
that  the  seeds,  or  kernels,  will  develop. 

Flowers— the  kind  bearing  pistils— now  appear  in  pairs  along 
the  sides  of  the  cob,  and  the  corn  "silk"  develops.  Each  strand  of 
silk  is  really  a  pistil,  with  the  stigma  at  the  upper  end  of  a  very 
long  style  (the  prolongation  of  the  ovary) .  In  order  to  secure 
pollen,  this  silk,  or  pistil,  must  extend  from  each  flower  to  the 
tip  of  the  cob,  and  beyond  the  leaf  wrapping. 

How  the  Corn  Plant  Is  Fertilized:  Meanwhile  brown  tassels  have 
appeared  at  the  top  of  the  main  stalk.  These  are  the  plant's  flowers 
which  bear  stamens  and  produce  pollen.  The  tassel  is  made  up 
of  many  florets,  each  having  two  anthers  hanging  from  it;  half 


The  Fascination  of  Flowers  [315 

of  each  anther  is  a  little  bag  of  pollen  grains.  When  the  pollen 
is  ripe,  this  bag  opens  and  the  grains  fall  on  the  silk  below.  The 
ends  of  the  silk  are  now  branched  and  covered  with  fine  hairs,  to 
catch  the  pollen. 

After  "landing,"  a  pollen  grain  goes  on  a  remarkable  journey- 
through  the  entire  length  of  the  corn  silk  until  it  reaches  the 
ovule.  Now  that  the  ovule  is  fertilized,  it  will  develop  into  a  kernel 
or  seed.  If  a  strand  of  silk  from  one  of  the  flowers  does  not  receive 
a  pollen  grain,  no  kernel  will  develop.  An  ear  with  some  of  these 
undeveloped  kernels  is  called  "imperfect."  If  pollen  from  another 
variety  of  corn  reaches  the  stigmas  of  the  silk,  the  ear  shows  a 
mixture  of  the  two  kinds  of  kernels. 

Self-Preservation  in  the  Corn  Plant:  Corn  stalks  are  so  tall  and 
slender  that  heavy  winds  can  damage  them  seriously.  Yet  the  struc- 
ture of  the  plant  provides  some  defense  against  wind.  The  cylinder- 
like stalk  with  its  pithy  center  is  sturdier  towards  the  base,  as  the 
hard  nodes,  or  joints,  occur  closer  together  there.  Towards  the 
top  the  nodes  are  farther  apart,  allowing  the  stalk  to  bend  with 
the  wind  and  recover. 

The  leaf  structure  also  affords  protection  against  the  wind.  The 
true  roots  go  deep  into  the  soil,  but  even  so  they  are  inadequate 
for  holding  a  tall  heavy  plant  upright  in  a  windstorm.  However, 
aside  from  these  roots  the  corn  has  other  roots  about  the  base  of 
the  plant— they  suggest  a  tentlike  frame— which  hold  the  stalk 
erect. 

Pumpkins— Source  of  Delicious  Pies 

Every  year  harvest  pictures  remind  us  that  corn  and 
pumpkin  are  constant  garden  companions.  A  child  may  guess 
that  these  two  vegetables  are  planted  together  because  one  grows 
high  while  the  other  barely  rises  above  the  ground.  The  real 
reason,  however,  is  found  in  the  nature  of  the  respective  roots: 
The  pumpkin  is  a  shallow-rooted  plant,  whereas  the  true  roots 
of  corn  go  deep  into  the  earth.  The  consequence  is  that  the  two 
plants  do  not  fight  each  other  for  minerals  and  water.

overshadows  its  flower  and  foliage.  The  rugged,  broad-based  leaves, 
with  their  three  to  five  lobes,  form  a  decorative  design  of  classic 
beauty.  The  delicately  curved  tendril  on  the  pumpkin  vine  is 
worth  observing.  Possibly  the  tendrils  are  a  holdover  from  a  remote 
past  when  pumpkin  vines  lifted  themselves  oflE  the  ground,  as 
certain  gourd  vines  do  today.  Occasionally  you  may  notice  a 
pumpkin  vine  reaching  out  as  it  climbs  on  the  edge  of  a  field, 
over  mounds  of  earth  or  fences  as  if  it  were  actually  a  climb- 
ing plant. 

Pumpkin  Seeds:  At  first  a  young  pumpkin  is  held  up  by  a  stiflE 
stem,  but  as  it  grows  heavier  it  rests  on  the  ground.  If  you  cut 
across  a  green  pumpkin,  you  will  notice  that  instead  of  a  cavity 
inside,  there  are  a  number  of  partitions  within  which  seeds  are 
borne.  (A  cucumber  has  much  the  same  arrangement.)  As  the 
pumpkin  ripens,  the  partitions  around  the  seeds  become  stringy— 
a  very  different  texture  from  the  "meat"  that  forms  a  thick  solid 
layer  between  the  skin  and  the  inner  chamber. 

The  pumpkin  is  a  plant  that  requires  no  aid  from  man  aside 
from  planting.  Another  favorable  trait  is  that  it  helps  to  check 
obnoxious  weeds. 

Weeds  Are  the  Farmer's  Enemy 

The  child  who  has  a  chance  to  work  in  a  garden  develops  a 
new  respect  for  nature— the  greatest  farmer  of  them  all.  As  he 
comes  to  realize  what  labor  and  skill  go  into  producing  plants, 
he  looks  appreciatively  at  natural  "crops"  that  no  man  has  aided. 
He  concludes  that  although  these  plants  which  cover  the  country- 
side may  be  attractive  and  have  certain  uses,  they  are  nothing 
but  weeds  if  they  spring  up  where  they  are  not  wanted. 

Weeds— Pests  That  May  Be  Beautiful 

Children  are  sometimes  perplexed  about  weeds.  We  usually 
speak  of  them  with  disdain  or  annoyance,  yet  the  flowers  that 
some  produce  are  as  lovely  as  those  we  carefully  tend  in  a  garden. 
It  is  not  the  looks  of  the  weeds  that  disturb  us;  their  ability  to 


The  Fascination  of  Flowers  [317 

produce  fantastic  numbers  of  seeds  makes  them  a  nuisance  in 
little  gardens,  and  a  serious  problem  to  farmers. 

Members  of  the  composite  family,  which  includes  daisies  and 
goldenrod,  are  among  the  chief  offenders;  bindweed  (a  morning- 
glory)  ,  devil's  paintbrush,  and  others  swell  the  ranks.  Because  of 
their  attractive  flowers,  many  types  of  weeds  were  intentionally 
brought  to  America  from  Europe,  where  they  had  been  kept  in 
check  by  the  nature  of  their  surroundings— farms,  forests,  and 
cities.  In  the  great  open  spaces  of  America  they  ran  wild,  and 
today  they  are  more  of  a  pest  than  a  pleasure. 

Wildflowers  to  Look  for  in  Springtime 

People  in  the  tropics  are  fortunate  in  having  flowering  plants 
throughout  the  year,  but  few  northerners  would  exchange  the 
joy  of  hunting  the  first  spring  flowers  for  all  the  luxury  of  endless 
blossoms. 

As  you  search  for  the  elusive  hepatica,  trillium,  and  other 
flowers  that  appear  soon  after  the  last  snows  have  melted,  you 
may  wonder  how  it  is  that  these  flowers  are  on  hand  in  so  short  a 
time  after  the  end  of  cold  weather.  After  all,  daisies,  irises,  and 
many  others  will  not  bloom  until  summer,  and  still  others— such 
as  asters  and  chrysanthemums— wait  almost  until  fall. 

Is  it  only  the  warm  weather  that  brings  forth  flowers?  If  so,  why 
do  plants  have  such  varying  timetables?  Here  is  the  answer:  Tests 
have  shown  that  plants  react  differently  to  the  amount  of  daylight 
they  receive.  Some  are  stimulated  to  bloom  by  short  days  and 
long  nights. 

At  first  it  sounds  contradictory  to  say  that  hepaticas  and  other 
early  spring  flowers  are  "short-day"  blossoms— they  make  their 
appearance  as  days  are  growing  longer!  However,  they  have  actu- 
ally been  formed  the  previous  year.  Formation  takes  place  under- 
ground; when  the  temperature  becomes  favorable,  these  flowers 
rise  up  into  the  light  and  air. 

On  a  quest  for  early  spring  flowers,  you  are  likely  to  observe 
that  many  of  them  are  white.  Later  in  the  season  you  will  find  more 
color.  There  is  a  definite  reason  for  this.  Flowers  formed  under 


3 1 8  ]  The  Fascination  of  Flowers 

ground  are  white  to  start  with  because  no  pigment  has  been 
developed.  When  they  are  exposed  to  light,  many  of  these  flowers 
take  on  various  hues,  among  them  blue,  red,  or  yellow. 

Hepaticas  Close  for  the  Night 

One  of  the  earliest  flowers  of  spring,  the  hepatica  must  be 
hunted  among  the  decaying  foliage  of  the  previous  fall.  As  its 
blossoms  grow  they  rise  about  three  inches  above  the  brownish 
leaves  of  the  year  before,  and  the  new  leaves  may  appear  very 
soon  after.  The  petal-like  sepals  are  white,  pink,  or  bluish- 
lavender.  Young  blossoms  close  during  the  night  and  on  dark 
days;  older  ones  remain  open  all  the  time. 

You  are  most  likely  to  find  the  wood  anemone,  a  member  of 
the  same  family  as  the  hepatica,  along  the  borders  of  woodlands. 
The  anemone  is  an  inch  or  more  taller  than  the  hepatica;  its 
flowers  are  white  or  delicate  purple. 

Adder's  Tongues  Are  LiLres 

Yellow  adder's  tongue  favors  moist  woods  and  brook  sides, 
though  it  sometimes  grows  in  open  fields  in  the  East.  White 
adder's  tongue  is  common  in  the  West  and  South.  The  small  bell- 
shaped  flowers  appear  in  early  spring,  but  the  leaves,  pale  green 
mottled  with  brownish  purple,  are  found  carpeting  large  irregular 
areas  long  after  the  blossoms  have  gone.  The  yellow  adder's 
tongue,  though  a  member  of  the  lily  family,  is  often  called  "dog- 
tooth violet." 

Violets— Not  Always  Shy 

In  the  true  violet  family  there  is  a  "dog"  violet  found 
especially  in  the  sandy  soils  of  the  Northwest.  This  is  a  low, 
creeping  species  with  light  purple  flowers.  Fairly  widespread  also 
is  the  downy  yellow  violet  which  blooms  almost  anywhere  in  low 
ground.  It  is  tall  in  comparison  to  most  violets— sometimes  as 
high  as  seventeen  inches. 

As  for  the  common  violet,  you  may  find  it  almost  anywhere  in 
low  ground.  As  a  rule,  the  deep  green  heart-shaped  leaves  usually 
grow  a  little  taller  than  the  flowers.  In  marshes,  however,  the

flower  stalks  are  longer  than  the  leaf  stalks  and  the  flowers  are 
exceptionally  large.  The  flowers  of  the  common  violet  range  from 
rich  purple  to  light  violet.  There  is  also  a  rare  variety  which  is 
white  with  purple  veins.

Trillium  for  Threefold 

The  season  for  trillium  begins  in  April  with  the  poetically 
named  wake-robin,  a  species  that  produces  purple,  red,  and  some- 
times purplish  flowers.  There  are  other  species,  but  it  will  be 
June  before  you  find  the  white  large-flowering  trillium.  It  is  this 
handsome  kind  that  flower-fanciers  often  cultivate. 

The  trilliums  grow  mostly  in  damp,  rich  wood  soils.  You  can 
help  children  in  identifying  these  flowers  if  you  explain  the  mean- 
ing of  "trillium,"  which  comes  from  the  word  triplum^  meaning 
"threefold."  These  flowers  always  have  three  petals  and  the  plants 
have  three  leaves  and  three  sepals. 

Jack-in-the-Pulpit— Miniature  Preacher 

No  plant  is  easier  to  remember  and  recognize  than  jack- 
in-the-pulpit,  for  to  an  imaginative  child  the  club-shaped  flower 
head  does  represent  a  miniature  preacher,  while  the  spathe  (a 
bract  or  modified  leaf)   forms  his  pulpit. 

Moist  woods  are  the  best  place  for  locating  this  plant.  When  it 
first  pushes  through  the  earth  it  looks  like  a  pointed  peg.  Inside 
the  p>ointed  and  mottled  sheath  are  the  leaves,  rolled  lengthwise 
and  forming  the  point.  The  club-shaped  spathe  is  at  the  center. 

As  the  leaves  grow  and  open,  flowers  develop  at  the  base  of  the 
spathe.  There  are  two  different  kinds;  greenish,  round  pistillate 
flowers,  packed  like  berries  on  the  stalk;  and  tiny,  almost  white 
flowers,  which  bear  the  pollen.  The  two  kinds  grow  on  separate 
plants.  You  may  sometimes  find  both  types  on  the  same  plant, 
with  the  pollen-bearing  kind  set  above  the  others.  In  such  a  case 
only  the  pollen-bearers  function. 

By  the  time  summer  comes  around,  the  "pulpit"  falls  away  from 
Jack,  revealing  shining  green  berries  formed  from  the  pistillate 
flowers.  In  August,  when  the  leaves  may  have  also  disappeared, 
you  will  find  that  the  berries  have  turned  a  brilliant  scarlet.

Cactus— Not  Just  a  Desert  Plant 

We  usually  associate  cactus  plants  with  the  desert.  Some 
cacti,  though,  thrive  in  such  contrasting  localities  as  the  high 
South  American  Andes  and  the  Pine  Barrens  of  New  Jersey. 

Many  varieties  of  this  hardy,  spiny  plant  have  been  adapted 
for  indoor  gardens,  so  you  don't  have  to  be  anywhere  near  a  desert 


322  ]  The  Fascination  of  Flowers 

to  enjoy  the  flowers  of  a  cactus.  (This  ought  to  interest  television- 
minded  children,  accustomed  to  viewing  hard-riding  cowboys 
among  desert  scenes!)  Cacti  may  bloom  in  your  home  any  time 
during  the  year— not  just  in  the  spring  as  the  desert  plants  do. 

It  is  in  the  springtime  that  we  see  desert  plants  at  their  best.  Out- 
standing are  the  pink,  yellow,  and  rose  blooms  of  the  prickly  pear, 
the  white  flowers  of  the  giant  sahuaro,  and  the  yellow  blossoms 
that  form  a  ring  about  each  round  column  of  the  barrel  cactus. 

Storehouses  of  Water:  Most  children  are  fascinated  by  the  curious 
forms  that  cacti  take.  They  can  see  some  of  these  plants  in  the 
hothouses  of  botanical  gardens,  and  they  are  very  likely  to  wonder 
about  their  lack  of  leaves.  Actually  the  cacti  do  very  well  without 
leaves. 

"Leaf-green"  in  their  thick  fleshy  stems  takes  care  of  manufac- 
turing their  food,  and  the  absence  of  leaves  prevents  the  water 
inside  the  plants  from  evaporating.  They  store  water  in  the  stems 
to  such  an  extent  that  they  can  survive  periods  of  drought  for  an 
amazingly  long  time.  Many  people  lost  in  the  desert  owe  their 
lives  to  these  natural  water  tanks. 

Plant  Survival  in  the  Desert:  In  humid  regions  plant  species  are 
largely  assured  of  survival  by  their  great  numbers.  In  deserts, 
where  plants  are  comparatively  sparse,  they  have  evolved  a  number 
of  defenses  to  keep  humans  and  animals  from  preying  on  them. 
Notable  are  the  spines,  thorns,  and  toughness  of  the  cactus.  Other 
plants  depend  on  bitterness  or  unpleasant  odors,  a  few  on  poison. 
Aside  from  cacti,  the  desert  offers  many  other  colorful  floral 
displays.  Visitors  from  near  and  far  are  attracted  every  year  to 
desert  areas— the  vicinity  of  Baker sfield  in  California,  for  example 
—to  see  lilies,  poppies,  violets,  primroses,  and  verbenas  blooming 
in  a  riotous  profusion  of  brilliant  colors.

Dandelions— Persistent  Weeds 

This  golden-headed  flower,  one  of  the  mast  persistent  of 
all  weeds,  is  occasionally  a  source  of  income  to  youngsters,  who 


The  Fascination  of  Flowers  [323 

earn  money  by  helping  rid  lawns  of  dandelions.  In  early  summer 
dandelions  can  provide  a  lot  of  fun  for  children.  The  youngsters 
can  whistle  through  the  hollow  stems,  or  make  dandelion  curls  of 
them;  they  may  even  pretend  to  tell  time  by  the  number  of  puffs 
required  to  blow  away  all  the  seeds  on  a  ripened  stem. 

The  Adaptable  Dandelion:  Children  have  done  such  things  to 
dandelions  for  ages,  man  has  tried  his  best  to  exterminate  them, 
animals  have  grazed  on  them,  other  plants  have  attempted  to 
crowd  them  out— all  in  vain.  The  dandelion  has  had  extraordinary 
success  in  surviving.  One  of  the  many  reasons  for  its  survival  is  its 
adaptability  to  circumstances.  For  example:  In  a  meadow  of  tall 
grasses  the  plant  sometimes  reaches  a  height  of  two  feet— and  more; 
but  on  a  lawn  the  flower  stem  may  be  less  than  two  inches  tall, 
saving  the  flower  head  from  the  blades  of  the  lawn  mower! 

The  Dandelion  is  a  Composite  Flower:  The  dandelion  belongs  to 
the  great  family  group  that  we  call  "composites"— a  word  that 
comes  from  the  Latin  and  means  "made  up  of  parts."  Aside  from 
the  dandelions,  the  composites  include  asters,  thistles,  and  a  great 
many  other  kinds  of  flowers.  All  have  compound  flower  heads  (the 
term  "head"  is  commonly  used  for  a  cluster  of  flowers) . 

Petals  and  Buds  in  the  Composites:  Some  of  the  composites  have  a 
disk  in  the  middle  of  the  flower  head.  This  disk  is  made  up  of  tiny 
tubular  florets,  and  around  it  are  brightly  colored  ray  flowers,  or 
petals. 

The  dandelion  belongs  to  another  type  of  composite  which  has 
a  petal-like  part  on  each  flower.  In  a  just-opened  dandelion  you 
can  see  the  buds  at  the  middle  all  curving  slightly  toward  the 
center.  They  are  also  shorter  and  a  darker  yellow  than  the  outer 
florets,  for  they  are  younger.  The  flower  head  is  well  protected 
by  long  bracts;  shorter  bracts  near  the  stem  curl  back,  forming  a 
frill. 

How  the  Dandelion  Opens  and  Closes:  Dandelions  close  on  dark 
days  and  at  night.  It  is  often  eight  o'clock  before  they  begin  to 
wake  up,  and  it  may  take  a  full  hour  for  the  golden  head  to  be 


324  ]  ^^^  Fascination  of  Flowers 

completely  opened.  When  all  the  florets  on  a  head  have  blos' 
somed,  the  dandelion  closes  for  good  until  its  seeds  are  formed. 
Each  seed  is  equipped  with  a  fluffy,  parachute-like  head.  When 
this  head  is  dry  it  can  "parachute"  the  seed  to  new  growing 
ground. 

How  the  Dandelion  Got  Its  Name:  You  need  a  good  imagination 
to  see  that  the  notched  edges  of  dandelion  leaves  resemble  lions' 
teeth;  but  that  is  what  they  looked  like  to  someone  in  France  who 
named  the  plant  dent-de-lion ^  whence  we  get  our  name  for  it. 

From  "Day's  Eye"  to  Daisy 

This  flower,  which  has  much  in  common  with  the  dande- 
lion, is  a  great  favorite  with  children.  Like  the  dandelion,  it  is 
an  amazingly  persistent  weed;  and  it  is  also  a  composite.  At  its 
center  we  find  numerous  short,  yellow,  tubular  disk  flowers. 

These  are  surrounded  by  twenty  or  more  ray  flowers— "petals" 
to  children,  who  love  to  pull  them  off  one  by  one  with  "he  loves 
me,  he  loves  me  not."  If  you  look  closely  at  these  ray  flowers  you 
will  see  that  each  has  a  pistil  which  shows  a  two-part  stigma  at 
its  base.  The  flowers  ripen  many  seeds  but  they  lack  the  traveling 
equipment  of  the  dandelion. 

In  the  yellow  daisy,  commonly  called  "black-eyed  Susan,"  the 
purple-brown  disk  flowers  form  a  conical,  button-like  center  for 
the  orange  ray  flowers.  Still  more  color  is  added  to  the  flower 
when  brilliant  orange  pollen  appears. 

Like  the  dandelion,  the  daisy  opens  in  the  morning.  It  owes  its 
name  to  this  trait— people  in  Old  England  called  it  "day's  eye," 
which  finally  became  our  "daisy." 

Buttercups— Sometimes  Three  Feet  High 

Growing  as  they  do  in  the  same  fields,  buttercups  and 
daisies  are  commonly  associated  in  children's  minds.  There  is  an 
essential  difference,  however;  whereas  the  daisy  is  a  composite, 
the  buttercup  is  a  single  flower.  The  five  (and  sometimes  more) 
wedge-shaped  petals  are  slightly  curved,  giving  the  flower  its  cup- 
like form. 


The  Fascination  of  Flowers  [  325 

*'Do  You  Like  Butter?":  The  bright  yellow  color  of  the  buttercup 
gives  it  a  shiny  finish  which  in  bright  sunlight  quite  easily  reflects 
on  another  surface.  That  is  why  the  answer  is  nearly  always  posi- 
tive when  a  child  follows  the  old  custom  of  holding  a  buttercup 
under  a  playmate's  chin  to  see  if  he  "likes  butter."  (If  yellow  is 
reflected  on  the  chin,  the  answer  is  "yes.")  Outside  the  reflecting 
petals  are  five  sepals,  about  half  the  length  of  the  petals  and  pale 
yellow  with  brownish  tips.  —  ~ 

There  are  many  different  kinds  of  buttercups;  the  common  one 
of  fields  and  meadows  is  properly  called  the  tall  buttercup.  It  may 
grow  as  tall  as  three  feet!  Though  you  are  likely  to  find  buttercups 
as  early  as  May,  they  bloom  through  August  and  sometimes  until 
frost  appears. 

Lucky  Clover 

Among  our  most  popular  superstitions  is  the  one  that 
promises  good  luck  to  the  finder  of  a  four-leaf  clover.  It  is  a  fact, 
however,  that  the  clover  plant  is  good  fortune  for  all  of  us. 

25,000  to  the  Inch:  In  addition  to  being  a  valuable  food  crop  for 
horses  and  cattle,  clover  has  an  almost  magical  way  of  bringing 
fertility  to  the  soil.  The  secret  of  this  power  lies  in  the  little 
swellings— sometimes  called  root  tubercles  or  nodules— that  you 
will  find  on  the  rootlets.  Each  swelling  is  occupied  by  bacteria, 
so  many  that  25,000  of  them,  lined  up,  would  cover  only  an  inch 
of  space. 

These  bacteria  extract  nitrogen,  a  valuable  chemical  fertilizer, 
from  the  soil  and  change  its  form  so  that  clover  can  absorb  it. 
When  a  crop  of  clover  is  harvested,  the  roots  remain  in  the  ground 
with  their  precious  supply  of  fertilizer.  This  is  one  reason  why 
farmers,  in  rotating  their  crops,  plant  clover  every  few  years. 

Collecting  Clovers  is  Fun:  It  is  fun  for  a  child  to  make  a  collection 
of  clovers,  for  there  are  many  attractive  species,  including  crimson, 
red,  white,  rabbit-foot,  buffalo,  and  yellow.  Both  leaves  and  blos- 
soms can  be  kept  for  several  years  when  pressed  between  pieces 
of  wax  paper  or  cellophane.  It  is  even  possible  to  become  an 
expert  at  finding  the  rare  four-leaf  clover  to  add  to  one's  collec-

tion.  These  leaves  turn  up  here  and  there  in  the  midst  of  stalks 
with  three  leaflets. 

The  three-leaved  grouping  is  the  customary  one  and  has  given 
the  plant  its  scientific  name,  trifolium   ("three-leaved") .  To  find 


The  Fascination  of  Flowers  [327 

the  out-of-the-ordinary  stalk  with  four  leaflets,  you  need  to  practice 
looking  for  a  square  pattern  in  a  carpet  of  triangles.  Stand  erect 
and  scan  the  clover  design;  where  one  four-leaf  specimen  is  found 
there  are  apt  to  be  more. 

Milkweed  and  its  Strain  ge  Secretion 

This  plant  has  two  products  that  fascinate  children:  its 
milky  juice  of  rubber-like  composition  and  its  skeins  of  shining 
silk.  To  see  the  "milk,"  all  they  need  do  is  break  the  stem  of  the 
plant  or  cut  across  a  leaf. 

The  "milk"  is  a  special  secretion— not  the  sap  of  the  plant.  If 
you  cut  across  the  stem  and  then  blot  the  end  so  that  you  can  see 
the  details  clearly,  you  will  find  that  the  liquid  oozes  from  a  dark 
green  ring  around  the  hollow  stem.  On  a  plant  that  is  only  par- 
tially broken  or  gashed,  the  "milk"  soon  heals  the  wound. 

Murder  by  Milkweed:  The  extremely  complex  flowers  growing  at 
the  junction  of  the  milkweed's  leaf  stem  and  plant  stem  are 
fertilized  mostly  by  bees.  Every  once  in  a  while  one  of  these  insects 
loses  its  life  on  the  flowers!  It  is  actually  trapped  by  the  anther, 
and  this  is  how:  Instead  of  being  free,  the  pollen  is  held  in  paired 
sacs  that  are  joined  in  a  V-shape.  The  bee,  busy  collecting  nectar, 
may  stand  in  the  V,  and  the  little  sacs  of  pollen-producing  anthers 
may  close  on  its  legs.  If  the  grip  is  too  tight,  the  insect  cannot 
free  itself. 

Milkweed  for  Life  Jackets  and  Aviators:  Once  the  milkweed 
flower  has  been  fertilized,  the  seed  pod  begins  to  grow.  The  fully 
developed  pod  bursts  apart  at  the  seam,  and  you  can  see  the 
brown,  overlapping  seeds  inside  with  exquisite  silk  attached  to 
one  end  of  each  seed.  When  the  silk  is  dry,  each  fluffy  mass  of 
threads  parachutes  off  in  the  breeze  carrying  a  seed  with  it— in 
some  cases  for  a  very  long  distance. 

Milkweed  floss  has  been  used  commercially  to  stuff  life  jackets- 
it  is  more  buoyant  than  cork— and  to  line  aviators'  uniforms,  as  it 
is  six  times  lighter  than  wool,  and  just  as  warm.

Queen  Anne's  Lace— Beautiful  Yet  Troublesome 
This  plant  is  very  beautiful,  as  its  name  suggests,  but  it  is 
also  a  very  troublesome  weed.  You  are  likely  to  find  it  in  waste 
places  and  fields  almost  anywhere.  It  is  also  called  the  wild  carrot, 
and  it  is  really  closely  related  to  the  garden  carrot.  On  a  fully 
grown  plant,  the  yellowish  root  is  six  inches  long  or  more;  but  it 
isn't  good  to  eat. 

The  Flower  Cluster:  Each  large  flat  flower  cluster,  with  its  radiat- 
ing pattern  as  fine  as  lace,  is  made  up  of  many  small  flower 
clusters,  each  in  turn  with  a  stalk  of  proper  length  to  fit  into  just 
the  right  place  in  the  medallion  pattern.  These  small  flower 
clusters  each  have  twenty  or  thirty  tiny  white  blossoms  in  a 
rosette  design. 

If  you  look  down  at  one  of  the  large  flower  clusters,  you  will 
notice  that  the  outside  blossoms  have  small  bracts— the  special 
leaves  which,  in  this  case,  resemble  the  petals.  These  are  larger 
than  the  petals  and  create  a  pleasing  border  effect  for  the  complete 
cluster.  Often  you  will  find  a  single  wine-colored  floret  in  the 
center  on  its  own  stalk. 

When  Queen  Anne's  lace  begins  to  wither,  each  of  the  small 
clusters  curves  inward  until  the  whole  unit  suggest  a  tiny  bird's 
nest.  Thousands  of  seeds  develop  on  each  plant,  and  many  live  to 
germinate. 

GoLDENROD— Another  Composite  Flower 

From  early  summer  to  late  fall  you  can  see  these  bright 
yellow  flowers  on  dry,  sandy  roadsides,  along  moist  riverbanks  and 
seashores,  at  the  edges  of  woods,  in  sunny  meadows,  in  moun- 
tainous regions,  and  on  flat  barren  plains.  In  all  these  localities 
there  are  many  kinds  of  goldenrod— more  than  fifty  all  told. 

The  goldenrod  is  another  interesting  example  of  a  composite 
flower.  Each  flower  head  is  very  small,  but  the  plant  makes  a 
bright  showing  because  the  florets  are  set  close  together.  On  each 
delicate  branch  there  is  a  procession  of  ray  flowers  with  short  but 
brilliant  banners,  and  a  few  tubular  disk  flowers  that  open  out 


The  Fascination  oj  Flowers  [329 

like  bells.  Look  at  the  disk  flowers  closely  and  you  will  see  in 
them  the  pollen  tubes  or  yellow  two-part  stigmas. 

Insects  of  many  shapes  and  sizes  carry  the  goldenrod's  pollen 
far  and  wide  for  it. 

Asters— ATTRAcrrvE  to  Beks 

Like  goldenrod,  asters  are  to  be  found  in  all  sorts  of  places, 
and  there  are  numerous  species.  They  too  are  composites,  but 
the  flower  heads  are  different  in  form  from  the  goldenrod.  At  the 
center  of  their  circular  flower  heads  there  are  yellow  disk  flowers 
that  turn  a  dull  purplish  color  as  they  age. 

These  disk  flowers  yield  an  abundance  of  nectar,  and  you 
frequently  see  bees,  small  butterflies,  and  beelike  flies  visiting 
them.  One  of  the  most  beautiful  and  best  known  is  the  New  Eng- 
land aster;  it  is  widespread  throughout  the  eastern  United  States 
and  is  frequently  cultivated.  Its  numerous  flowers,  blooming  from 
August  to  October,  vary  in  hue  from  pale  violet  to  deep  purple. 

Some  Sunflowers  are  Twelve  Feet  High 

Because  of  its  size,  this  giant  plant  serves  best  of  all  to 
show  us  the  make-up  of  a  composite  flower.  One  wild  species— 
the  "tall  sunflower"— is  common  to  swamps  and  the  borders  of 
wet  meadows.  It  grows  as  high  as  twelve  feet  and  has  a  flower 
head  about  two  inches  across.  On  the  common  garden  sunflower 
the  flower  head  may  have  a  width  of  ten  inches. 

First  to  unfold  are  the  wide,  flaring  ray  flowers  that  are  largely 
responsible  for  the  sunflower's  spectacular  appearance.  There 
may  be  two  or  three  rows  of  these.  When  they  are  a  few  days  old, 
you  can  see  inside  them  a  circle  of  florets  from  which  ripened 
pollen  and  stigmas  have  already  disappeared.  Below  the  florets 
fertilized  seeds  are  now  developing. 

Inside  this  circle  is  another  composed  of  florets  where  coiled- 
back  stigma  lobes  protrude  from  the  anther  tubes.  Next,  moving 
toward  the  center  of  the  flower  head,  you  may  see  several  rows  of 
florets  in  which  pollen  is  just  being  pushed  out;  and  within  this 
ring  may  be  florets  with  the  anther  tubes  still  closed.  At  the  center

Sunflower  Myths:  Children  who  have  not  had  a  chance  to  observe 
sunflowers  may  be  interested  to  know  if  it  is  true  that  these  blos- 
soms twist  on  their  stems  in  order  to  face  the  sun  all  day.  This 


The  Fascination  of  Flowers  L  33  i 

widely  circulated  story  is  charming  but  not  particularly  accurate. 
Some  of  these  giant  flowers  have  been  observed  turning  with  the 
sun  to  a  certain  extent  when  they  first  unfold— but  not  after  they 
grow  heavy  with  seeds. 

Another  published  observation  is  that  many  turn  for  their  last 
few  weeks  of  bloom  to  the  east  and  remain  that  way.  Watching 
those  that  grow  in  my  neighbor's  garden— they  are  planted,  by 
the  way,  to  raise  seeds  for  her  winter  bird-feeding  station— I  have 
not  seen  any  evidence  of  the  flower  heads  following  the  sun.  The 
direction  they  usually  face  is  south. 

Wildflower  Bouquets  and  Gardens 

Part  of  the  joy  of  flowers  comes  from  picking  them  and  arrang- 
ing them  in  enchanting  bouquets.  Unfortunately,  we  are  limited 
for  the  most  part  to  garden  plants.  Many  wild  species  have  become 
so  rare  that  they  are  protected  by  law;  others,  such  as  wild  roses 
and  asters,  though  plentiful,  wilt  quickly  after  they  are  plucked. 

What  Flowers  to  Choose 

Despite  these  limitations,  we  still  have  some  excellent 
material  for  wildflower  bouquets.  The  common  blue  violet  is  one 
of  the  very  few  spring  flowers  not  on  the  "protected"  list  of  most 
states,  and  in  summer,  buttercups,  daisies,  black-eyed  Susans,  gold- 
enrod,  and  Queen  Anne's  lace  lend  themselves  to  charming  floral 
decorations. 

When  you  have  a  chance  to  pick  wildflowers,  it  is  best  to  cut 
them  with  scissors  or  regular  garden  clippers.  Later,  the  stems 
should  be  cut  on  a  slant  with  a  sharp  knife.  Then,  if  they  are  left 
in  a  pail  of  water  for  a  few  hours  or  overnight,  they  may  regain 
much  of  their  freshness. 

Growing  a  Wildflower  Garden 

Few  hobbies  are  more  delightful  than  a  wildflower  garden. 
With  very  little  trouble  you  can  transplant  daisies,  black-eyed 
Susans,  and  certain  other  hardy  species,  making  them  thrive  close 
to  your  home.  You  can  usually  move  even  the  rarer  plants,  such 


^^2  ]  ^^^  Fascination  of  Flowers 

as  red  milium,  violet,  and  wild  geranium,  if  you  take  along  a 
generous  amount  of  earth.  As  a  matter  of  fact,  many  commercial 
growers  specialize  in  quite  rare  plants;  you  can  obtain  the  wild- 
flowers  in  this  way  when  it  is  not  feasible  to  take  them  from  their 
native  growing  places. 

How  to  Press  and  Mount  Plants 

Pressing  wildfiowers  is  still  another  way  in  which  children  can 
get  pleasure  from  them.  They  can  also  have  a  world  of  fun  arrang- 
ing the  flowers  in  attractive  groupings  and  framing  them  as  wall 
pictures.  You  will  again  want  to  stress  to  youngsters,  before  they 
do  any  picking,  that  only  plants  that  are  plentiful  should  be  taken. 
It  is  well  for  children  to  make  a  habit  of  asking  their  parents  about 
protected  wildfiowers  before  doing  any  picking.  The  parents  can 
then  check  conservation  laws  with  local  authorities. 

Techniques  for  Pressing  Flowers:  When  you  collect  plants  for 
pressing,  keep  them  damp  until  you  are  ready  to  place  them  under 
pressure.  You  can  manage  this  by  taking  a  few  damp  newspapers 
on  a  collecting  trip  and  carrying  the  plants  between  the  pages. 
For  ease  of  handling,  you  can  roll  up  the  papers— not  too  tightly, 
however,  or  the  leaves  may  crack. 

When  you  are  ready  for  pressing,  place  a  piece  of  newspaper 
about  twelve  by  eighteen  inches  on  the  floor,  and  lay  plants  or 
flowers  on  top  of  it.  As  you  may  want  to  frame  them  later  on, 
take  care  to  arrange  petals,  and  leaves  in  natural  positions.  A 
violet,  for  example,  usually  looks  more  natural  if  pressed  in  pro- 
file. A  few  buds  with  the  full-bloom  flower  and  some  leaves  make  a 
complete  story  and  an  interesting  composition.  Make  sure  that  no 
plants  overlap  during  the  pressing. 

How  to  Dry  Out  Plant  Moisture:  Now  that  you  have  laid  out  the 
plants  on  newspaper,  cover  this  arrangement  with  a  layer  of  news- 
paper equal  in  thickness  to  the  thickest  part  of  the  plant  or  plants 
below.  Add  layers  of  plants  and  paper  until  your  entire  collection 
is  taken  care  of.  Over  this  pile,  place  a  board  or  other  flat  object 
equal  in  size  to  the  newspaper,  and  on  top  of  this  put  weights 


The  Fascination  of  Flowers  [333 

such  as  books,  rocks,  or  other  heavy  things.  If  the  weight  is  not 
heavy  enough,  the  plants  will  wrinkle. 

Change  the  paper  or  move  the  plants  to  a  dry  location  every 
day  for  at  least  four  days— then  less  often,  for  about  ten  days.  The 
more  rapidly  the  plant  loses  its  moisture,  the  better  its  delicate 
colors  will  be  preserved. 

How  to  Mount  Plants:  To  mount  a  plant  you  need  a  piece  of 
glass  as  large  as  the  specimen  you  are  preparing.  Cover  the  glass 
with  a  thin  coating  of  glue  diluted  a  bit  with  a  drop  or  two  of 
vinegar.  Place  the  dried  plant  on  the  glue  (to  get  the  glue  on 
one  side) ,  then  quickly  transfer  the  plant  to  a  piece  of  mounting 
paper.  Now  you  are  ready  for  framing.  If  a  plant  is  too  delicate 
for  this  treatment— it  may  curl  when  it  is  picked  up  from  the 
glue— you  can  mount  it  by  placing  thin  strips  of  gummed  paper 
at  intervals  across  the  stem. 

Some  Plants  Have  No  Green  Parts 

Knowing  as  we  do  how  vital  "leaf-green"  is  to  the  growth  of 
plants,  the  mushroom  and  other  fungi  that  develop  without  a 
trace  of  green  seem  rather  mysterious  to  us.  No  wonder  that 
generations  ago,  when  not  too  much  was  known  about  plant  life, 
people  stood  in  superstitious  awe  of  the  magic  "toadstools,"  which 
seemed  to  spring  out  of  nowhere  and  were  sometimes  good  food 
and  sometimes  poisonous.  When  you  are  on  a  woodlands  hike 
with  your  youngster,  especially  in  late  summer  or  early  fall,  you 
can  get  a  lot  more  out  of  your  trip  if  you  watch  for  members  of 
this  fungus  family  growing  wild. 

What  Fungi  Feed  On 

Lacking  leaf-green,  mushrooms  are  unable  to  manufacture 
starch,  sugar,  and  other  elements,  and  must  absorb  them  from 
dead  wood,  withered  leaves,  or  soils  enriched  by  remains  of  plants. 
They  are  the  kind  of  fungi  we  know  as  "saprophytes"  (living  on 
dead  or  decaying  matter) ,  and  they  are  valuable  plants  because 
they  prevent  forests  from  becoming  choked  with  dead  wood.  As 


^^^  ]  The  Fascination  of  Flowers 

mushrooms  and  other  fungi  absorb  tissue  from  stumps  and  old 
logs,  the  wood  softens  and  falls  apart. 

Fungi  That  Prey  on  Living  Things 

The  other  kinds  of  fungi,  the  "parasites,"  take  their  food 
from  the  cells  of  living  things.  These  fungi  are  often  dangerous 
enemies  to  the  plants  and  animals  on  which  they  grow.  It  is  a 
parasitic  fungus  that  causes  "potato  blight";  another  is  responsible 
for  the  costly  disease  known  as  "wheat  rust."  The  simplest  forms 
of  parasitic  fungi  that  take  their  nourishment  from  animals  are 
the  bacteria  that  cause  diphtheria,  typhoid  fever  and  other  serious 
diseases. 

Mushroom  Spores  Instead  of  Seeds 

As  mushrooms  have  no  flowers,  a  child  may  wonder  what 
they  do  about  seeds.  Flowerless  plants  have  their  own  special  kind 
of  "seed."  Microscopic  in  size,  it  is  called  a  "spore."  After  landing 
in  a  favorable  growing  place,  the  spore  of  a  mushroom  develops 
rapidly  into  a  threadlike  form.  From  this  a  whole  mass  of  threads 
grow  out  for  weeks  or  even  months,  until  there  is  enough  tissue 
to  produce  a  fruiting  body— then,  with  startling  suddenness,  the 
mushroom  appears! 

Precautions  Against  Poisonous  Mushrooms 

Mushrooms  are  usually  abundant  in  damp,  wooded  spots, 
as  they  do  not  need  sunshine.  If  we  happen  to  be  in  one  of  these 
localities,  we  may  be  tempted  to  find  some  mushrooms  suitable 
for  eating.  It  is  a  temptation  best  denied.  Unfortunately  some 
people  rely  on  tests  that  are  supposed  to  indicate  when  a  species 
is  poisonous— they  believe  such  mushrooms  turn  a  silver  spoon 
black  or  change  color  when  bruised.  None  of  these  tests  are  of 
the  slightest  value.  A  number  of  characteristics  do  help  to  dis- 
tinguish the  poisonous  from  the  nonpoisonous  species,  but  only 
an  expert  should  attempt  to  draw  the  distinction  for  eating 
purposes. 


The  Fascination  of  Flowers  [  335 

Mosses  Favor  Moist  Places 

There  is  a  shrub  known  as  the  "flowering  moss,"  but  you  can 
be  sure  it  is  not  really  moss— no  moss  bears  flowers.  The  so-called 
flowering  moss  merely  suggests  moss  in  a  superficial  way  because 
of  its  appearance. 

Mosses,  like  mushrooms,  produce  spores.  The  moss  spore  grows 
a  branched  green  thread  on  which  leafy  buds  soon  appear.  They 
develop  further  into  leafy  stems  which  in  turn  produce  rootlike 
projections— not  true  roots.  Some  of  the  plants  bear  eggs  at  their 
leaf  tips  while  others  produce  sperms.  Wind,  or  films  of  water 
supplied  by  rain  or  dew,  may  bring  sperm  and  egg  together.  After 
fertilization  they  develop  delicate  upright  stalks  on  which  spore 
cases  full  of  green-colored  spores  will  form. 

The  Moss  as  a  Compass 

In  June  you  can  generally  see  mosses  in  all  stages  of  devel- 
opment. Usually  you  find  moss  only  in  rather  moist  places,  on 
woodland  floors  and  on  rocks  and  tree  trunks  where  strong  sun- 
light does  not  penetrate.  The  American  Indians  commonly  used 
this  bit  of  nature  lore  to  determine  their  direction— moss  usually 
grows  on  the  northern  side  of  tree  trunks  where  there  is  least 
exposure  to  sunlight. 

The  Best-known  Moss 

What  is  probably  the  best-known  moss  has  several  names: 
common  hair-cap,  bird  wheat,  or  pigeon  wheat  moss.  It  grows  not 
only  in  woods  but  in  open  fields  and  meadows  as  well  as  in  all 
parts  of  North  America;  it  is  found  also  in  Europe  and  Asia.  It 
is  rather  a  large  moss  with  stems  a  foot  long,  and  in  fall  or  winter 
you  will  see  it  as  a  greenish-brown  mass  of  bristling  stems. 

By  the  arrival  of  summer  the  new  growth  tips  these  with  vivid 
green.  During  dry  spells  the  small  leaves  shut  lengthwise  into 
mere  threads  and  huddle  against  the  stem  to  prevent  their 
moisture  from  evaporating.  After  a  rain  they  open  up  again.  In 
Europe  this  moss  is  used  for  making  small  brooms  and  for 
mattresses. 


336  ]  The  Fascination  of  Flowers 

Ferns,  Fronds,  and  ^Tiddle  Heads'' 

Mosl  children  love  ferns  as  much  as  they  do  flowers.  Ferns 
lack  colored  petals,  but  by  way  of  compensation  they  have  grace- 
fully shaped  fronds,  or  leaves,  that  are  a  delight  to  the  eye  from 
the  time  they  come  through  the  ground  and  uncoil  like  a  watch 
spring  until  the  divided  leaves  are  fully  developed.  While  the 
leaves  are  still  partly  coiled  they  are  called  "fiddle  heads,"  as 
their  shape  resembles  the  top  of  a  violin. 

Fbrns  for  Decoration 

Ferns  are  frequently  cultivated  and  used  for  decoration; 
consequently  a  fernery  makes  a  very  rewarding  project.  To  begin 
with,  the  ground  for  a  fern  garden  should  be  dug  up  and  treated 
with  well-rotted  leaves  and  humus.  When  you  transplant  speci- 
mens from  the  woods,  take  a  large  ball  of  earth  with  each  plant, 
and  water  the  ferns  well  for  several  days  after  each  planting.  Give 
the  ferns  the  same  conditions  of  shade  and  sunshine,  as  far  as 
possible,  as  they  had  in  the  natural  state. 

Among  the  most  attractive  species  are  the  Christmas  fern  of 
the  East  and  its  close  relative,  the  sword  fern  of  the  West.  They 
are  very  similar  in  appearance— except  that  the  sword  fern  grows 
much  larger. 

Ferns  and  their  Spores 

Ferns,  like  the  mosses  and  mushrooms,  produce  spores. 
Some  ferns  also  have  a  creeping  underground  stem,  called  a  "root- 
stock,"  which  pushes  forward  and  sends  up  new  fronds  each  year. 
One  species  is  known  as  the  "walking  fern"  because  new  growth 
is  started  where  the  tips  of  the  fronds  come  in  contact  with  ground 
or  rocks.  Look  closely  at  a  Christmas  fern  in  early  spring  and 
you  will  notice  on  the  underside  of  some  of  the  leaflets  a  double 
row  of  circular,  raised  fruit  dots,  looking  like  pale  blisters. 

Later  on  these  "dots"  turn  brown,  and  by  the  middle  of  June 
masses  of  pinpoint-size  globules  push  out  from  under  them.  Each 
globule  is  a  case  packed  with  spores  so  tiny  that  even  under  a 
magnifying  glass  thev  look  like  yellowish  powder.  By  July  the 


The  Fascination  of  Flowers  [  337 

brown  covers  have  shriveled  into  irregular  scrolls  but  still  cling 
to  the  ferns. 

Fronds  and  Frondlike  Foliage:  Not  all  fronds  are  fertile.  The  in- 
fertile ones— those  without  the  fruit  dots— are  much  prettier. 
Coming  back  to  the  fertile  fronds,  the  brown  spots  are  not  always 
recognized  as  being  covers  of  spore  cases;  many  people  take  them 
for  fungus  growths.  Another  cause  for  confusion  is  that  Queen 
Anne's  lace  and  other  plants  with  frondlike  foliage  look  enough 
like  ferns  to  be  mistaken  for  them.  A  good  test  in  case  of  doubt  is 
to  examine  the  center  of  the  plant  to  see  if  the  leaves  are  rolled 
into  a  coil.  If  they  are,  you  are  almost  certainly  looking  at  a  fern. 

How  to  Make  Fern  Printa 

You  can  press  fern  fronds  by  using  the  methods  described  for 
flowering  plants  (page  332) .  A  child  will  also  enjoy  making  blue 
prints  of  fronds,  and  here  is  how  it  is  done: 

You  can  buy  sheets  of  blueprint  paper  in  any  store  which  sells 
artists'  supplies.  Keep  the  paper  in  the  dark  at  all  times;  the 
safest  course  is  to  keep  it  rolled  and  wrapped  up  in  other  paper. 
You  will  also  need  a  picture  frame  with  a  glass  and  tight-fitting 
cardboard  back.  Then  you  can  cut  the  blueprint  paper  into 
sheets  the  size  of  the  picture  frame— always  being  careful  to  avoid 
exposing  the  blueprint  paper  to  light. 

Finally,  take  two  shallow  pans,  each  somewhat  larger  than  your 
sheets  of  blueprint  paper,  fill  them  half  full  with  cool  water, 
and  add  a  teaspoon  of  hydrogen  peroxide  to  one  of  the  pans  of 
water.  Now  your  equipment  is  complete. 

Printing  the  Fronds 

A  bright  sunny  day  is  best— but  not  essential— for  your 
blueprinting  operations.  Working  in  a  dimly  lighted  room,  place 
the  picture  frame,  glass  down,  on  a  table  and  remove  the  card- 
board back.  Place  the  ferns  on  the  glass,  and  lay  over  them  a  sheet 
of  blueprint  paper  with  its  greenish-blue  side  down,  against  the 
ferns.  (Fronds  that  have  been  pressed  for  a  day  or  two  may  give 
better  prints  than  those  freshly  picked.)

Now  replace  the  cardboard  and  fasten  it  firmly.  The  frame  is 
ready  to  be  exposed  to  sunlight  at  a  window  or  outdoors— from 
two  to  five  minutes  depending  on  the  intensity  of  the  sunlight. 
After  exposure,  remove  the  blueprint  paper  from  the  frame  and 
let  it  soak  in  the  pan  of  clear  water.  In  a  few  minutes,  after  the 
background  of  the  fern  has  turned  white,  transfer  the  paper  to 
the  other  pan  of  water  to  which  the  peroxide  has  been  added.  In 
this  second  bath— which  fixes  the  print— the  background  will  turn 
a  deep  blue  and  the  outline  of  the  frond  will  appear  in  white. 

You  can  now  remove  the  paper,  wash  it  again  in  the  clear 
water,  and  dry  it.  Dry  the  print  between  blotting  paper  or  paper 
towels  and  leave  it  for  several  hours  pressed  between  books  or 
other  heavy  objects  until  it  is  completely  flat  and  dry.  This  project 
can  be  managed  even  by  a  fairly  young  child,  and  the  process  can 
be  used  not  only  for  ferns  but  for  a  collection  of  all  kinds  of 
leaves  as  well. 

Nature's  Fern  Prints 

Countless  ages  ago  nature  made  fern  prints  of  a  somewhat 
different  sort.  Today  workers  in  coal  mines  frequently  find  these 
"prints"— for  they  are  a  part  of  the  great  coal  deposits  in  Ohio, 
Pennsylvania,  and  other  regions.  When  our  earth  was  several  hun- 
dred million  years  younger,  ferns  and  their  relatives  were  the 
principal  land  plants.  The  massive  but  weak  fern  trees  crashed 
down  and  gradually  filled  swamps  and  marshes. 

Later  the  pressure  of  overlying  sand  and  mud  that  drifted  and 
oozed  over  these  regions  turned  the  fern  masses  into  peat  and 
finally  into  coal.  As  this  was  happening  the  outline  of  an  occa- 
sional fern  frond  was  imprinted  in  the  slate  or  rock  which  formed 
from  the  muddy  deposits  as  it  pressed  against  the  vegetation  which 
was  changing  into  coal.  These  ancient  prints  reveal  that  the 
appearance  of  ferns  has  not  changed  much  in  all  these  millions 
of  years. 


CHAPTER 


I  Trees  and  How 
to  Know  Them 


OST  ADULTS  sccm  to  take  trees  for  granted, 
but  in  the  child's  world  they  loom  large. 
They  are  natural  play  equipment,  to  be  climbed  for  fruit  or  for 
fun.  City  children  are  doubly  grateful  for  them  in  summertime, 
when  the  hot  sun  blisters  the  pavements  and  the  only  comfortable 
place  to  play  is  under  widespread,  sheltering  leaves. 

There  are  other  reasons  for  appreciating  trees— because  they  give 
homes  to  the  birds  and  squirrels,  and  yield  to  man  the  wood  that 
he  uses  in  so  many  ways.  Even  a  young  child  cannot  remain  un- 
moved by  the  beauty  of  the  trees:  the  majesty  of  their  boughs  and 
rugged  bark,  the  changing  colors  of  their  leaves,  the  splendid 
bounty  of  their  fruit,  blossoms,  and  cones.  No  wonder  that  most 
children  love  the  trees  and  delight  in  telling  the  seasons  by  these 
living  calendars. 

Tree  Rings  and  What  They  Tell  Us:  You  can  find  the  record  of  a 
tree's  growth  in  the  trunk  or  a  branch  that  has  been  cut  across. 
There,  in  the  wood,  are  the  rings  that  mark  each  year  of  its  life. 
In  adding  to  its  girth  the  tree  depends  on  a  layer  of  cells  called 
"cambium,"  which  lies  just  inside  the  protective  bark.  Each  year 
the  cambium  builds  a  layer  of  bark  on  its  outer  side  and  a  layer  of 
wood  on  the  inner  side. 

During  spring  and  early  summer,  when  conditions  for  growth 
are  most  favorable,  wood  cells  develop.  During  late  summer  and 

339 


340  ]  Trees  and  How  to  Know  Them 

early  fall,  new  though  somewhat  smaller  wood  cells  are  still  pro- 
duced. During  the  winter,  growth  stops  entirely.  When  it  resumes 
once  more  with  "spring  wood"  next  to  "fall  wood,"  the  contrast 
between  the  two  kinds  of  wood  produces  a  line  around  the  trunk. 
This  line  we  know  as  the  "annual  ring." 

How  Trees  Record  Their  Autobiographies:  In  a  sense  the  annual 
rings  are  the  biography  of  the  tree— wide  spaces  between  rings 
indicate  good  growing  years,  whereas  narrow  spaces  tell  of  seasons 
of  drought  or  other  climatic  conditions  unfavorable  to  growth. 
A  series  of  rings  with  little  space  between  them  at  the  center  of 
the  trunk,  changing  to  wider-spaced  rings  toward  the  bark,  might 
also  be  a  clue  to  improved  growing  conditions.  The  thinning  out 
of  surrounding  trees,  for  example,  would  provide  more  sunlight 
and  the  roots  would  have  less  competition  for  the  water  and 
minerals  of  the  soil. 

Annual  growth  rings  are  common  to  most  of  the  trees  that 
grow  in  North  America.  But  in  some  regions,  such  as  the  rainy 
tropics,  there  is  no  distinct  growing  season.  There  tree  growth  is 
constant,  and  the  wood  has  a  more  uniform  structure  instead  of 
annual  rings.  When  these  trees  are  sawed  into  boards  they  do  not 
show  the  intricate  grain  that  our  trees  do;  what  we  call  the  "grain" 
is  simply  the  annual  growth  rings  sawed  lengthwise. 

Watching  a  Tree  Develop 

In  attaining  its  height,  a  tree  does  not  merely  stretch  up- 
ward. If  you  observe  one  from  the  time  it  is  a  sapling  until  it  is  a 
mature  tree,  you  will  see  that  the  height  of  the  lowest  limb  always 
stays  at  exactly  the  same  distance  from  the  ground.  It  gains  height 
as  a  result  of  "leaders"  at  the  top  of  the  tree. 

Buds— New  Life  for  the  Tree:  If  you  open  a  bud  from  the  tip  end 
of  a  branch  in  wintertime,  you  will  find  tiny  but  perfectly  formed 
stems,  leaves,  and  perhaps  clusters  of  flowers.  Many  of  our  familiar 
trees  produce  all  these  in  the  same  bud;  others,  like  the  American 
elm,  have  twigs  and  leaves  in  one  type  of  bud,  flowers  in  another. 
The  buds,  folded  neatly  and  tightly,  are  protected  by  scales  that 
overlap  like  shingles  on  a  roof. 


Trees  and  How  to  Know  Them  [341 

In  the  spring  you  can  see  the  buds  open  when  the  scales  are 
cast  off  and  the  new  twigs  lengthen  and  form  new  side  branches. 
On  most  trees  the  new  twigs  are  only  a  few  inches  long,  but  on 
some  the  growth  is  more  noticeable. 

How  to  Grow  Tree  Buds  Indoors:  Children  can  observe  this  un- 
folding at  close  range  by  putting  a  few  twigs  of  different  kinds  of 
trees  into  vases  partly  filled  with  water.  Collect  the  twigs  in  the 
fall  after  the  leaves  have  been  shed,  and  cut  them  carefully  with  a 
sharp  knife.  Through  the  winter,  change  the  water  each  week  and 
rinse  the  twigs  in  cool  water  to  keep  the  bud  scales  fresh  and 
clean— a  task  performed  out-of-doors  by  winter  rains  and  snow. 

If  you  keep  the  twigs  in  a  warm,  fairly  dark  place,  the  buds 
will  enlarge  ahead  of  those  on  the  trees  outdoors.  When  the  buds 
seem  almost  ready  to  burst,  they  should  be  moved  to  a  sunny 
window. 

Trees  Have  Their  Own  Birthday  Candles:  Trunks  are  not  the 
only  parts  of  trees  that  have  growth  marks.  Branches  and  twigs 
have  them  too,  and  you  don't  have  to  cut  down  a  tree  to  see  them. 
Every  year  a  bud  leaves  a  little  circle  of  scars  as  it  casts  off  its 
scales.  Consequently  the  distance  between  every  two  circles  of 
scars  on  the  branch  shows  the  growth  achieved  in  a  year's  time. 
An  imaginative  child  will  enjoy  likening  the  bud  scars  to  birth- 
day candles— by  counting  them  he  finds  the  age  of  any  twig. 

Bursting  at  the  Seams:  The  child  who  makes  a  habit  of  observing 
some  of  the  details  of  tree  structure  will  soon  notice  that  while 
young  trees  have  smooth  bark,  that  of  older  trees  is  furrowed  and 
frequently  sheds  untidily.  This  also  is  caused  by  growth;  as  the 
girth  of  the  trunk  increases,  the  constant  pressure  causes  the  bark 
to  split.  A  special  layer  of  cells  in  the  bark  forms  new  corky  layers 
that  patch  the  damaged  parts  but  do  not  smooth  the  "wrinkles" 
that  have  formed.  Trees,  like  people,  often  look  their  age. 

How  Trees  Are  Nourished 

Though  we  cannot  see  a  tree  obtain  its  food  the  way  we  can 
watch  an  animal  feed,  we  can  observe  to  some  extent  how  the  leaf 


342  ]  Trees  and  How  to  Know  Them 

"factories"  secure  the  materials  with  which  they  work.  Put  a  leafy 
twig  into  ink  and  you  will  see  how  the  color  is  carried  up  through 
the  wood  into  the  leaves.  The  minerals  and  water  taken  from  the 
earth  by  the  rootlets  are  carried  in  much  the  same  way  up  the 
larger  roots,  on  up  into  the  sapwood  of  the  trunk,  and  out  through 
the  branches  and  twigs  to  the  leaves. 

When  you  look  carefully  at  the  leaves  you  can  see  many  veins 
that  serve  as  channels  for  spreading  water  and  minerals.  From 
these  raw  materials,  and  with  the  help  of  sunlight,  the  leaves 
produce  a  sugary  liquid  that  travels  back  to  the  trunk  and  through 
the  fibers  of  the  innermost  layer  of  bark  to  all  parts  of  the  tree 
to  nourish  it. 

The  work  of  making  food  and  distributing  it,  goes  on  through- 
out the  spring  and  early  summer.  By  midsummer  the  tree  has 
achieved  most  of  its  growth  for  the  year  and  it  can  begin  to  store 
extra  food  in  its  trunk,  branches,  twigs,  and  roots.  During  the 
winter  the  tree  rests;  the  following  spring  the  reserve  food  is  avail- 
able to  help  buds  open  and  new  leaves  can  begin  to  grow. 

The  Most  Famous  Tree  Food  of  All:  At  this  point  maple  sugar 
and  maple  syrup  come  into  our  story.  Everyone  knows  they  are 
processed  from  the  sap  of  the  maple  tree— but  what  makes  that 
sap  so  deliciously  sweet?  As  it  surges  through  the  maple  trees  in 
springtime,  the  sap  dissolves  the  sugar  they  have  stored  up.  Thus 
sugar  and  sap  flow  out  together  into  containers  the  canny  Ver- 
monters  have  mounted  under  holes  they  make  in  the  trunks. 
Boiling  does  the  rest. 

Why  Leaves  Change  Color  and  What  Makes  Them  Fall 

As  children  first  notice  the  reds  and  yellows  about  the  time  of 
the  first  cold  snap,  they  often  conclude  that  frost  causes  the  leaves 
to  change  from  green  to  bright  fall  coloring.  As  it  happens,  frost 
is  not  the  cause,  though  lower  temperatures  do  have  some  bearing 
on  the  change.  With  the  coming  of  colder  weather  the  earth  starts 
to  harden  and  the  trees  are  no  longer  able  to  draw  much  water 
from  it. 


Trees  and  How  to  Know  Them  [  343 

Lacking  water,  the  green  pigment  of  the  leaves  begins  to  fade 
and  is  gradually  replaced  by  yellow  and  orange  pigments  that  have 
been  present  all  along  but  in  smaller  quantities  than  the  green. 
Red  coloring  has  a  different  origin:  It  is  formed  in  the  cell  sap 
by  the  same  sort  of  "dye"  that  colors  red  cabbage  and  beets.  You 
can  look  for  lovely  red  displays  on  sugar  maples,  white  oaks,  and 
sumac. 

Poplar,  hickory,  and  linden  are  some  of  the  trees  that  Have 
golden-yellow  fall  coloring.  The  green  pigment  of  evergreens  is 
so  hardy  that— as  we  might  guess  from  the  name  of  this  tree— it  is 
not  affected  by  winter  conditions. 

How  Leaves  Die  and  Drop  Off:  While  the  leaves  are  changing 
color,  a  thin  corklike  layer  of  cells  develops  between  the  leaf  stems 
and  the  twigs  to  which  they  are  fastened.  This  layer  of  weak  tissue 
reduces  or  shuts  off  completely  the  flow  of  sap  to  the  leaf.  This  not 
only  contributes  to  the  death  of  the  leaf— it  also  weakens  its  attach- 
ment so  that  it  falls  at  a  slight  breeze  or  even  from  its  own  weight. 

How  Knots  and  Knotholes  Are  Formed 

Trees  Prune  Their  Own  Branches:  Children  often  have  the 
opportunity  to  watch  trees  being  pruned  in  city  parks  or  on 
suburban  lawns.  But  they  are  surprised  to  learn  that  trees  growing 
under  natural  conditions  are  also  pruned.  The  trees  do  this 
pruning  themselves!  One  process,  called  natural  pruning,  works 
like  this:  Lower  branches  become  undernourished  because  exces- 
sive shade  prevents  their  leaves  from  manufacturing  food,  with 
the  result  that  these  branches  die  and  drop  off. 

In  willows,  poplars,  and  other  trees,  layers  of  weak  tissue, 
similar  to  those  that  cause  leaves  to  fall,  form  somewhere  along 
certain  branches— sometimes  at  the  base.  After  a  while  the 
branches  break  off,  even  though  many  fresh  leaves  may  still  be 
attached  to  them.  This  process  is  known  as  self-pruning. 

Knotholes  and  Peepholes:  When  a  branch  is  lost  to  a  tree  by 
pruning,  the  remaining  short  stump  of  branch  eventually  becomes 
overgrown  by  the  trunk.  If  the  tree  is  felled  and  cut  for  lumber, 


344  ]  Trees  and  How  to  Know  Them 

the  end  of  the  branch  shows  up  as  a  knot.  In  cases  where  the 
branch  was  quite  dead  when  it  dropped  from  the  tree,  the  knot 
is  a  dead  one  and  falls  out  readily,  leaving  a  knothole— a  boon  to 
many  a  child  who  wishes  to  peep  through  a  board  fence. 

The  Underground  Life  of  Trees 

Trees  vary  in  many  respects,  but  all  kinds  are  alike  in  being 
made  up  of  two  main  parts.  Every  tree  has  a  trunk  and  a  crown— 
or  head— which  is  made  up  of  branches  and  spray  (the  term  used 
for  its  great  mass  of  twigs) .  We  can  easily  see  this  part  of  the  tree, 
but  there  is  another  big  section  which  is  concealed. 

Below  the  Surface:  The  root  system  of  a  tree  is  often  so  extensive 
that  its  size  would  equal  that  of  the  crown  if  this  upper  part  were 
somewhat  compressed.  The  roots  of  some  species  grow  almost 
straight  down;  other  species  have  roots  extending  outward  close 
to  the  surface  of  the  ground.  Certain  oak  trees  have  been  found 
with  roots  two  or  three  times  as  widespread  as  their  branches! 

Sometimes  roots  that  have  pushed  partly  above  the  surface  help 
a  child  to  picture  the  extent  of  a  root  system— or  he  may  come 
upon  an  uprooted  stump  to  which  roots  are  still  attached.  City 
youngsters  occasionally  see  work  being  done  on  pavements  or 
watch  the  installation  of  pipes  under  sidewalks  which  uncovers 
or  cuts  into  the  roots  of  shade  trees.  They  may  well  be  impressed 
by  the  amount  of  abuse  the  trees  will  take,  yet  there  are  limits  to 
the  damage  that  a  tree  can  stand. 

Repairing  Injured  Roots:  Often  the  injured  roots  require  treat- 
ment. Sometimes  it  is  enough  to  trim  away  the  ragged  edges;  in 
other  cases  the  broken  sections  should  be  removed  completely.  If 
any  considerable  amount  of  root  material  is  taken  away  when  a 
tree  is  transplanted,  the  crown  should  also  be  trimmed.  This  re- 
duces the  needs  of  the  foliage  for  food  and  water  at  a  time  when 
the  root  system  can  no  longer  do  its  full  part  in  providing  them.

Keeping  a  Tree  Biography 

Once  a  child  has  a  general  understanding  of  tree  growth,  he 
will  very  likely  enjoy  keeping  a  record  of  one  particular  specimen. 
Choose  a  tree  fairly  near  home  so  that  he  can  observe  it  often: 
about  once  a  week  in  spring  and  fall  and  every  two  weeks  in 
summer  and  winter.  If  he  looks  at  it  closely  for  just  a  few  minutes 
at  a  time,  he  will  see  whatever  developments  there  are:  buds  notice- 
ably larger,  buds  opening,  flowers  blossoming,  fruits  forming,  and 
so  on  through  changing  leaf  colors  to  bare  branches. 

Insects  found  on  the  tree,  birds  nesting  in  it,  or  squirrels  using 
it  for  their  home— these  are  all  part  of  the  story.  Such  a  record 
kept  in  a  notebook  may  be  illustrated  with  a  few  sketches  of  the 
tree's  changing  silhouette,  its  leaves,  flowers,  or  fruit.  At  the  end 
of  the  year  the  youngster  is  quite  sure  to  have  felt  something  of 
the  fascination  of  first-hand  observation,  and  to  have  an  increased 
interest  in  all  trees. 

How  to  Recognize  the  Trees 

Certain  trees  have  something  so  special  about  them  that  chil- 
dren have  no  trouble  remembering  them.  The  drooping  form  of 
the  weeping  willow,  the  bark  of  the  slender  white  birch— these  are 
quite  unforgettable.  However,  you  will  find  dozens  of  trees  in 
your  own  neighborhood  that  look  more  or  less  like  many  others. 
It  would  be  rash  to  conclude  that  it  is  quite  impossible  to  recog- 
nize them  all;  there  are  numerous  ways  in  which  each  reveals  its 
name  to  us. 

Oaks— Grandeur,  Strength,  Endurance 

If  there  are  oak  trees  in  your  neighborhood,  you  might 
begin  with  this  group.  So  impressive  are  the  grandeur,  strength, 
and  endurance  of  the  oak  that  it  is  frequently  used  as  a  symbol  of 
these  qualities  in  literature  and  art.  The  oak  group  has  many 
different  members.  It  is  not  always  easy  to  identify  each  of  its 
species;  there  are  numerous  kinds  that  vary  in  size,  type  of  leaf, 
and  other  features.

Trees  and  How  to  Know  Them 


Usually,  though,  an  oak  is  ponderous,  with  scaly  or  furrowed 
bark.  The  leaves  are  marked  by  prominent  branching  veins  and 
the  winter  buds  are  clustered  at  the  ends  of  the  twigs.  These  buds 
are  covered  with  chestnut-brown  scales  which  leave  a  ringlike 
mark  on  the  twig  when  they  fall.  All  oaks  are  alike  in  producing 
those  delightfully  sculptured  seed  containers,  the  acorns. 

The  White  Oaks:  All  oaks  are  divided  into  two  classes:  white  oaks 
and  black  oaks.  In  identifying  a  member  of  the  white  group— 


"GREAT  OAKS  FROM  UHLE  ACORNS  GROW 

The  mighty  white  oak,  with  branches  that  may  extend  fifty  feet  or  more,  develops 
from  a  seed  that  may  be  only  three-quarters  of  an  inch  long.  Its  wood  is  a  great 
favorite  where  durability  is  needed;  it  is  used  in  shipbuilding,  for  railroad  ties 
and  cars,  flooring,  agricultural  implements. 


Trees  and  How  to  Know  Them  [  347 

which  includes  the  white  oak  proper,  the  bur,  post,  and  Cali- 
fornia white  oak— it  helps  to  examine  the  leaves.  They  have 
characteristically  rounded  lobes  (segments) ,  though  the  chestnut 
oak  is  a  well-known  exception  with  its  long  narrow  leaves.  Usually 
they  are  light-colored  on  the  underside. 

Another  characteristic  of  these  trees  is  the  grayish  or  light- 
brown  bark  which  you  may  often  notice  breaking  off  in  loose, 
flaky  scales.  (This,  again,  is  not  true  of  the  chestnut  oak.)  Acorns 
of  the  white  oaks  mature  in  one  year;  you  will  never  see  acorns 
of  old  and  new  crops  on  a  tree  at  the  same  time. 

The  Black  Oaks:  The  black  oak  group,  by  contrast,  has  leaves 
with  angular  lobes,  ending  in  sharp  points.  Members  of  this 
group,  including  the  black,  pin,  red,  scarlet,  Spanish,  and  willow 
oaks,  require  two  years  to  mature  their  acorns;  so  you  may  observe 
fully  grown  acorns  started  the  previous  year  and  the  new  crop 
clinging  to  the  branches  at  the  same  time. 

As  for  differentiating  oak  species,  you  will  find  such  distinc> 
tions  as  the  pin  oak's  horizontal,  slender  branches  that  arch  out 
gracefully  and  on  the  lower  part  of  the  tree  droop  and  spread  out 
into  fine  branchlets  most  unusual  for  an  oak.  The  willow  oak  is 
distinctive  in  that  its  slender  leaves  have  no  lobes.  The  black  oak 
has  rough,  dark  bark  growing  in  ridges;  the  bark  of  the  scarlet 
oak  is  even  rougher.  The  red  oak's  acorns  are  large  and  set  in 
broad,  shallow  cups  especially  adaptable  for  the  toy  cups  and 
saucers  that  children  enjoy  fashioning  from  them. 

Many  oaks  do  not  begin  to  produce  acorns  until  they  are  about 
twenty  years  old.  Oaks  are  comparatively  slow-growing  and  long- 
lived;  you  may  find  some  that  have  apparently  been  growing  for 
several  centuries. 

Oak  Buds:  There  are  noticeable  differences  in  the  shapes  of  oak 
buds.  On  most  of  the  white  oaks  they  are  blunt;  on  black  oaks 
they  are  large  and  sharp-pointed.  They  also  differ  in  color.  All 
oaks  do  have  a  family  resemblance,  however,  in  the  way  several 
buds,  all  fairly  equal  in  size,  cluster  at  the  tip  of  a  branch  or  twig. 
(Other  trees  may  have  only  one  bud  at,  or  near,  the  tip  of  the 


^^8  ]  Trees  and  How  to  Know  Them 

branch.  Still  others  may  also  have  several  placed  like  the  buds 
of  the  oaks;  but  in  such  cases  the  buds  are  very  unequal  in  size.) 

The  Sturdy  Oak:  The  sturdy  wood  of  the  oak  has  played  a  great 
role  in  our  history.  Pioneers  built  blockhouses,  log  cabins,  bridges, 
and  bams  of  oak.  Gun  deck,  keel,  and  other  parts  of  the  frigate 
Constitution  were  made  of  white  oak,  and  all-oak  ships  were  built 
for  years.  Today  oak  is  still  a  wood  of  great  importance.  It  is  used 
especially  for  flooring  and  furniture  and  serves  the  United  States 
Navy  in  mine  sweepers  and  patrol  boats. 

Maples 

Sugar  Maples:  The  form  of  the  sugar  maple  is  determined  by  the 
conditions  under  which  it  grows.  When  there  is  plenty  of  room 
the  tree  has  a  short  trunk  and  an  oval  head;  in  a  forest  its  granite- 
gray  trunk  in  search  of  sunlight  may  reach  a  height  of  a  hundred 
feet  while  its  leaves  and  branches  blend  with  the  surrounding 
foliage  to  form  the  forest's  green  canopy.  The  glossy  leaves,  dark 
green  above  and  pale  beneath,  have  five  main  lobes  between  the 
edges  marked  with  a  few  large  teeth. 

When  the  leaves  fall,  you  see  a  silhouette  with  many  branches— 
these  divide  into  fine  spray— set  close  at  sharp  angles  to  the  trunk. 
You  can  notice,  too,  a  fine  graduation  in  color  as  the  dark  gray  of 
the  trunk  shades  to  lighter  tones  on  the  branches.  The  spray  is 
purplish— the  color  of  the  long  sharp-pointed  winter  buds.  In  late 
winter  the  bud  scales  become  downy  and  turn  almost  golden. 
Soon  afterward  you  see  them  pushed  off  by  the  yellowish,  downy 
leaves.  Greenish-yellow  flowers  appear  at  the  same  time,  grouped 
in  tassel-like  clusters. 

The  sugar  (or  rock)  maple's  hard,  close-grained  wood  is  used 
in  much  of  our  high-quality  furniture. 

Red  Maples:  Other  species  of  maple  native  to  America  can  also 
be  distinguished  quite  readily.  The  red  maple  gets  its  name  from 
usually  having  something  red  about  it.  It  has  red  buds  in  winter 
and  early  spring;  in  late  spring  the  flowers  are  most  frequently

THE  VERSATILE  SUGAR  A\APLE 

In  early  spring  this  maple  yields  delicious  sweet  sap.  During  the  summer  its  leaves 
provide  glorious  shady  shelter.  With  the  coming  of  autumn  the  crimson,  orange, 
and  yellow  coloring  of  the  leaves  makes  the  tree  a  work  of  art.  In  winter,  with 
the  leaves  gone,  we  can  appreciate  the  fine  tracery  of  the  sugar  maple's  branches 
and  twigs.  This  hardy  tree  may  live  as  long  as  three   hundred  years. 


red  (though  sometimes  yellow) ;  the  leaf  stalks  in  summer  are 
noticeably  red;  and  in  fall  the  leaves  are  a  lovely  crimson  or 
wine-red. 


Silver  Maples:  These  maples  turn  a  pale  yellow  in  the  fall.  In 
summer  you  can  appreciate  their  interestingly  two- toned  leaves: 
bright  pale  green  above  and  silvery  white  below.  Whenever  the 


350  ]  Trees  and  How  to  Know  Them 

wind  ruffles  this  foliage,  a  silver  maple  may  seem  to  change  before 
your  eyes  from  an  ordinary  green  hue  to  silver.  This  tree  is  the 
fastest  growing  of  all  our  maples  and  attains  a  good  size. 

Bigleaf  Maples:  The  bigleaf  maples,  found  along  the  Pacific  coast 
from  Alaska  to  southern  California,  have  the  largest  leaves  of 
any  native  maple.  They  may  be  as  long  as  twelve  inches,  and  their 
width  is  slightly  greaterl 

Norway  Maples:  The  Norway  maple  is  one  of  several  species  in- 
troduced to  America  for  ornamental  planting.  Its  leaves  are  very 
much  like  those  of  the  sugar  maple,  but  they  are  broader  than  they 
are  long.  If  you  break  one  of  the  leaf  stalks,  a  milky  juice  will 
ooze  forth.  The  bark  of  the  Norway  maple  is  dark  gray  and  fairly 
smooth;  its  twigs  are  about  twice  as  thick  as  those  of  a  sugar  maple. 

Seeds  with  Wings:  What  acorns  are  to  the  oaks,  the  paired,  winged 
seeds  are  to  the  maples.  Any  time  after  the  first  of  June  you  may 
look  for  maple  seeds  on  the  sidewalks,  roads,  and  woods.  In  the 
case  of  the  sugar  maple,  though,  the  seeds  do  not  fly  until  the  fall. 
Sometimes  maple  seeds  have  two  wings  attached,  other  times  a 
wing  is  broken  off.  Though  they  have  the  appearance  of  two  sepa- 
rate seeds  joined  together,  usually  only  one  seed  of  the  pair  is 
developed. 

The  twin  green  wings  do  a  good  job  of  carrying  seeds  to 
new  growing  grounds.  Children  are  quick  to  appreciate  their 
efficiency  and  similarity  to  man-made  gliders. 

Sycamores— Massive  Shade  Trees 

You  will  easily  recognize  this  massive  tree  in  winter  as  well 
as  summer  by  its  mottled  whitish  bark,  its  thick  trunk,  and  its 
broad  oval  crown.  However,  the  bark  takes  on  a  variety  of  forms 
and  colors  according  to  the  sycamore's  age  and  the  conditions 
under  which  it  is  growing.  Until  it  is  moderately  old,  large  thin 
plates  of  bark  peel  off,  exposing  areas  of  whitish,  yellowish,  or 
greenish  inner  bark— probably  the  result  of  the  outer  bark's  in- 
ability to  expand. 


Trees  and  How  to  Know  Them 


[351 


THE  UNPREDICTABLE  SYCAMORE 

Young  sycamores  ore  generally  flat  at  the  bottom  and  round  at  the  top,  but  as 
they  age  their  forms  show  interesting  individuality.  The  branches  spread  and  twist 
at  every  angle,  and  their  leaves,  broader  than  long,  provide  heavy  foliage.  Some 
sycamores  grow  tall  straight  trunks,  others  have  trunks  dividing  close  to  the  ground. 


In  older  trees,  the  bark  is  two  or  three  inches  thick  and  broken 
by  numerous  shallow  fissures.  This  results  in  a  scaly  appearance, 
and  the  light-colored  mottled  look  is  replaced  by  dark  gray  or 
reddish  brown. 

"The  Button-Ball  Tree":  The  inconspicuous  flowers  of  the  syca- 
more blossom  when  the  leaves  unfold  early  in  May.  By  October, 
the  fruit  that  develops  from  them  provides  an  excellent  "trade- 


252  ]  Trees  and  How  to  Know  Them 

mark."  It  is  a  dense  ball  about  an  inch  thick  which  is  green  at 
first  but  later  turns  brown. 

Because  of  this  button-like  fruit,  the  sycamore  is  sometimes 
called  the  button-ball  tree  or  buttonwood.  A  "button"  dangles 
from  a  long  slender  stem  throughout  the  winter.  When  spring 
arrives,  the  button  breaks  up  into  many  hairy  nutlets. 

Sycamores  are  chiefly  useful  as  shade  trees,  but  their  wood  is  of 
some  value  for  musical  instruments. 

American  Elms— Graceful  and  Tough 

In  summertime  this  tree,  when  it  is  growing  in  the  open, 
is  likely  to  remind  you  of  a  huge  vase  filled  with  foliage.  From  its 
rounded  wide-spreading  top  it  tapers  downward  in  the  manner  of 
many  graceful  flower-holders.  After  it  sheds  its  first  foliage,  you 
will  notice  how  the  trunk  divides  gradually  at  ten  to  twenty  feet 
above  the  ground  into  two  or  more  stout  branches.  The  gray  bark 
is  furrowed  in  perpendicular  flat-topped  ridges. 

The  Elm's  Purplish  Haze:  In  early  spring  you  may  wonder 
whether  your  eyes  are  deceiving  you,  or  if  there  really  is  a  purple 
glow  over  that  elm  tree  a  short  distance  ahead  of  you.  Your  eyes 
are  not  playing  tricks:  The  purple  haze  is  produced  by  clusters 
of  light-green  blossoms  with  red  stamens,  all  over  the  tree.  Seeds 
develop  from  them  even  before  the  leaves  are  fully  open  in  May 
or  June;  they  are  flat  and  surrounded  by  a  broad  papery  wing. 
When  the  seeds  are  planted,  some  may  germinate  within  a  few 
days;  many,  however,  remain  dormant  until  the  next  spring. 

Lopsided  Leaves:  The  leaves  of  this  elm  have  the  peculiarity  of 
being  lopsided;  one  side  of  each  leaf  is  larger  than  the  other. 
Their  parallel  veins  are  evenly  spaced  and  go  directly  from  the 
midrib  to  the  sawtooth  edges.  The  upper  surface  is  somewhat 
rough  and  the  undersurface  softly  hairy. 

What  Elm  Wood  Is  Used  For:  The  wood  of  this  tree  is  so  hard 
as  to  make  it  impractical  for  many  uses;  yet  the  very  hardness  of 
elm  wood  makes  it  ideal  for  such  purposes  as  the  hubs  of  heavy

THE  AMERICAN  ELM  -  GRACEFUL  SHADE  TREE 

Many  trees  derive  their  graceful  charm  from  their  foliage,  but  the  American  elm  is 
lovely  for  its  shape  as  well.  Its  lower  branches  sweep  upward  and  bend  at  the  ends; 
the  higher  branches  form  a  rounded  top  with  a  multitude  of  slender  twigs.  This 
arrangement  gives  the  elm  an  attractive  vaselike  outline. 

wagons,  floors  that  must  take  considerable  punishment,  and  chop 
ping  boards  and  bowls.  The  more  this  wood  is  scrubbed,  the  more 
it  shines. 

Some  Other  Elms:  The  American  elm,  sometimes  also  called  the 
white  elm,  grows  naturally  on  low,  fertile  hills  and  river  bottom 
lands.  Of  the  other  species  of  elm  native  to  America,  the  slippery 
elm  is  next  in  importance.  It  rather  resembles  its  larger  relative 
but  lacks  its  graceful  symmetry.  The  whitish  inner  bark  of  the

slippery  elm  is  very  gummy  (though  quite  tasteless) ,  and  chewing 
it  is  fun  for  children. 

Poplars— Including  the  Quaking  Aspen 

Of  the  eleven  different  members  of  the  poplar  group  that 
we  find  in  North  America,  the  quaking  aspen   (or  aspen  poplar) 
carries  to  the  furthest  extreme  the  family  characteristic  of  having 
foliage  that  trembles  with  the  breeze.  The  small  broad  leaves  of 
this  poplar  quiver  almost  incessantly  even  when  the  air  is  calm. 


THE  RESTLESS  FOLIAGE  OF  THE  QUAKING  ASPEN 

The  slightest  breeze  sets  in  motion  the  foliage  of  this  poplar.  Its  dark  green  leaves, 
which  turn  clear  gold  in  autumn,  are  attached  by  long  ribbon-like  stems.  Its  twigs 
and  bark  of  blotched  white  keep  many  a  rabbit  alive  in  winter,  and  its  bitter  inner 
bark    is   a  favorite   food   of  beavers.   It  is  also   known   as  the   trembling   aspen. 


Trees  and  How  to  Know  Them  [  355 

The  Quaking  Aspen:  The  quaking  aspen's  leaves  are  shiny  green 
above  and  pale  dull  green  below;  in  the  fall  they  turn  golden 
yellow  some  time  before  they  are  shed.  In  spring  the  quaking 
aspen  flowers  appear  in  the  form  of  drooping  catkins— a  compact 
spike  of  flowers  from  an  inch  and  a  half  to  two  and  a  half  inches 
long. 

Young  trees  have  yellowish-green  or  nearly  white  powdery  bark 
which  is  marked  with  horizontal  creases  and  scars.  On  old  trees 
the  bark  near  the  base  is  almost  black,  and  roughened  by  bands 
of  wartlike  growths.  For  years  the  wood  was  considered  quite 
worthless.  Today  it  has  a  very  real  value  as  a  source  of  paper, 
especially  magazine  stock. 

The  Popular  Cottonwood:  Another  widespread  and  well-known 
poplar  is  the  cottonwood.  You  are  likely  to  encounter  it  on  dry 
western  plains  where  other  trees  cannot  gain  a  foothold— or  in  a 
large  city  where  its  shiny,  leathery  leaves  successfully  shed  smoke 
and  dirt.  However,  many  cities  prohibit  the  planting  of  the  cotton- 
wood  because  its  extensive  shallow  root  system  often  breaks  up 
sidewalks  and  its  tiny  rootlets,  in  their  quest  for  water,  fill  drain- 
pipes. 

Cottonwoods  Grow  Fast:  Children  who  are  impatient  for  things 
to  grow  up  can  enjoy  watching  cottonwoods  develop.  These  trees 
have  been  observed  adding  four  or  five  feet  to  their  height  in  a 
year;  some  have  grown  a  hundred  feet  in  fifteen  years.  This  is 
rather  more  than  average  height  for  a  cottonwood,  yet  you  may 
find  one  growing  as  tall  as  150  feet,  given  favorable  conditions. 
It  develops  a  massive  trunk  that  divides  near  the  ground. 

Willows— Generally  Found  Near  Water 
Children  are  quickly  attracted  to  some  of  the  willows.  One 
introduction  is  all  they  are  likely  to  need  to  the  huge  but  ex- 
tremely graceful  willow,  with  its  long,  narrow,  pointed  leaves, 
some  of  which  droop  to  the  ground.  A  boy  with  his  first  jackknife 
loves  the  willow  because  the  bark  is  easily  removed  in  whole  sec- 


356  ]  Trees  and  How  to  Know  Them 

tions  from  branches  or  twigs  and  can  be  used  to  fashion  a  variety 
of  whistles. 

The  wood  of  the  willows  has  a  few  practical  uses  but  most  mem- 
bers of  this  group,  especially  the  weeping  willow  (an  import  from 
Asia),  are  mostly  valued  for  their  grace  and  beauty. 

The  Pussy  Willow— Children's  Favorite:  The  pussy  willow,  a  great 
joy  to  children,  is  related  to  the  weeping  willow  though  they  differ 
considerably  in  size.  The  pussy  willow  rarely  reaches  a  height  of 
twenty  feet.  Its  prominent  soft  pussies  are  welcomed  as  one  of  the 
first  promises  of  spring  and  enjoyed  for  their  silky  "fur"  as  much  in 
florists'  shops  as  in  their  natural  setting. 

Willow  Seeds  and  Pollen:  There  are  quite  a  few  other  species  of 
varying  sizes  and  characteristics,  but  they  all  have  the  distinctive 
elongated  catkins  (scaly  spikes),  and  our  American  willows  bear 
long  narrow  leaves  that  turn  yellow  in  the  fall.  In  each  species  the 
seed-bearing  flowers  and  the  pollen-bearing  flowers  are  produced 
on  separate  trees. 

The  showy  pussies  are  pollen-bearing  flowers.  In  winter  they 
are  covered  by  a  shiny  brown  tentlike  bract.  When  these  open  you 
can  see  two  stamens  and  anthers  (the  pollen  bearers)  underneath 
each  fur-bordered  scale.  But  you  will  find  no  pistils. 

On  another  tree,  however,  you  may  discover  greenish-gray  cat- 
kins, similar  to  the  ones  just  described,  but  not  so  soft  and  furry. 
In  these,  each  fringed  scale  has  a  pistil  at  its  base,  and  projecting 
from  it  is  a  Y-shaped  stigma  that  is  fertilized  by  the  pollen  and 
produces  the  seed.  You  can  observe  the  process  closely  by  keeping 
a  few  in  water  until  the  catkins  open. 

At  the  base  of  both  kinds  of  flowers  are  small  glands  of  nectar. 
Bees  make  their  way  to  these,  and  as  they  do  they  carry  pollen  to 
the  pistils.  Wind  also  plays  a  role  in  the  pollination  project.  When 
the  willow  seeds  ripen  in  June,  you  find  the  catkins  made  up  of 
tiny  pods.  When  the  seeds  pop  open,  they  are  equipped  with  fuzz 
and  fly  away,  balloon-fashion.  A  frequent  comment  is,  "The 
willows  are  shedding  cotton."

[357 


WHY  WILLOWS  ARE  FOUND  AT  WATERSIDES 

We  are  so  accustomed  to  seeing  willows  at  the  edges  of  streams,  that  these  trees 
have  come  to  seem  most  "at  home"  there.  As  a  matter  of  fact,  the  planting  of 
willows  near  stream  bonks  has  practical  value;  their  roots,  powerful  and  extensive, 
hove  a  restraining  effect  on  the  soil  and  help  hold  it  in  place  in  case  of  a  flood. 


Willows  and  Their  Roots:  Willows  are  most  likely  to  be  found 
near  water,  and  they  are  valuable  in  controlling  watercourses  in 
floodtime  because  of  their  extensive  roots.  By  placing  willow  twigs 
in  water  you  can  demonstrate  how  easily  they  form  rootlets.  A 
twig  lying  on  moist  soil  will  develop  them  in  the  same  way  along 
its  entire  underside  as  shoots  appear  from  the  buds  on  the  upper 
side.

Beeches— Handsome  and  Practical 

If  there  are  beech  trees  in  your  neighborhood,  your  chil- 
dren are  likely  to  be  familiar  with  the  nuts  even  though  they  pay 
scant  attention  to  the  rest  of  the  tree.  By  early  fall  they  are  ripe 
and  edible— two  or  three  small  triangular,  highly  polished  nuts 
enclosed  in  a  small  prickly  bur.  Another  distinctive  characteristic 
of  the  beech  is  its  smooth,  blue-gray,  skinlike  bark  which  hugs 
trunk  and  branches,  even  on  old  trees. 


THE  HARDY  AND   LONG-LIVED   AMERICAN    BEECH 

The  American  beech,  a  relative  of  the  oaks,  has  striking  beauty  of  form,  foliage 
and  bark.  This  hardy  and  long-lived  tree  is  easy  to  recognize  by  its  smooth  gray 
bark.  The  family  name  of  the  beech,  Fagus,  comes  from  a  Greek  word  meaning 
to  "eat"— perhaps  a  reference  to  the  tasty  beech  nut,  which  makes  good  eating. 


Trees  and  How  to  Know  Them  [  359 

From  Beech  to  Book:  This  bark  offers  youngsters  a  tempting 
opfK>rtunity  to  carve  their  initials  on  its  smooth  surface.  The  idea 
of  using  it  as  a  slate  is  far  from  new!  It  is  said  that  centuries  ago 
in  Europe  some  of  the  first  writing  was  done  on  beech-bark  strips, 
and  there  is  an  interesting  connection  between  the  words  beech 
and  hook.  Beech  comes  from  the  Anglo-Saxon  heeche,  to  which 
our  word  hook  is  closely  related. 

What  Beech  Wood  is  Used  For:  Though  unsuitable  for  important 
building,  beech  has  a  number  of  practical  uses,  serving  for  such 
humble  articles  as  boxes,  crates,  barrels,  and  clothespins.  Seeing 
one  of  these  handsome  trees  with  its  many  long,  wide-spreading 
branches,  you  are  hardly  likely  to  associate  it  with  such  lowly 
though  essential  products. 

The  glossy,  dark  blue-green  leaves  of  the  beech  are  between 
three  and  five  inches  long,  and  each  vein  ends  in  a  small  sharp 
tooth.  The  leaves  sometimes  cling  stubbornly  to  the  branches 
throughout  the  winter. 

Ash  Trees— Pliant  But  Tough 

Of  the  eighteen  different  species  of  ash  growing  in  the 
United  States,  the  white  ash  is  the  largest  and  handsomest.  You 
may  discover  it  on  a  variety  of  soils— most  often  on  well-drained 
fertile  sites  along  streams  and  on  north  or  east  slopes.  Its  compact, 
oval  head  is  a  rich  green  that  derives  from  the  dark  tone  of  the 
lancelike  leaflets.  These  are  the  compounded  type  of  leaf;  from 
five  to  nine  short-stalked  blades  are  attached  to  each  leaf  stem. 

Possibly  the  ash  got  its  name  from  its  dark  ashy  gray  bark.  In 
any  event  the  color  of  the  bark  serves  as  a  reminder  of  the  tree's 
name.  The  bark  is  cut  by  deep  diamond-shaped  fissures  with  broad 
flattened  ridges  between  them.  The  seeds  are  equipped  for  flight, 
each  being  enclosed  in  a  single  wing. 

Ash  for  Baseball  Bats:  There  are  not  many  purposes  for  which  the 
white  ash  is  esteemed,  but  some  of  the  special  uses  to  which  it  is 
put  provide  a  lot  of  fun  for  boys  and  girls.  White  ash  is  the  only 
wood  used  for  making  good  baseball  bats,  and  it  is  excellent  for

BATS.   PADDLES,   SKIS,    HOCKEY   STICKS 

The  wood  of  the  white  ash  is  ideal  for  many  kinds  of  sports  equipment,  including 
baseball  bats,  canoe  paddles  (this  goes  back  to  Indian  times),  frames  for  tennis 
racquets,  skis,  polo  and  hockey  sticks.  Incidentally,  the  tree  of  the  universe  in 
Norse  mythology  (Igdrasil)  was  a  white  ash. 


tennis  racquet  frames,  hockey  sticks,  skis,  and  other  sports  equip- 
ment. What  makes  it  peculiarly  suitable  for  these  purposes  is  that 
it  is  pliant  yet  tough.  It  can  be  bent  into  the  required  shapes, 
but  it  is  durable  enough  to  stand  up  under  strenuous  use. 

Black  ash  wood  also  serves  specialized  purposes:  It  splits  easily 
into  very  thin,  yet  tough  pieces,  and  as  a  result  makes  ideal  barrel 
hoops  and  woven  chair  bottoms.

Birches— From  Canoes  to  Furniture 

The  Paper  Birch:  It  is  a  pity  that  the  bark  of  this  graceful  tree 
appeals  so  much  to  children;  the  temptation  to  peel  strips  from 
the  trunk  is  usually  irresistible,  with  the  result  that  countless  trees 
are  disfigured  or  fatally  injured.  Some  children  may  have  the  good 
fortune  to  fashion  some  article  or  other  from  a  birch  that  must  be 
felled;  but  as  a  rule  parents  need  to  admonish  them  against  mis- 
treating standing  trees.  We  have  to  hoard  our  natural  resources 


BIRCH  BARK  FOR  CANOES 

Long  before  the  arrival  of  the  white  man  in  America,  the  Indians  were  using  the 
bark  of  the  paper  birch  for  their  canoes.  Though  the  paper  birch  varies  in  form 
all  the  way  from  a  bushy  and  rather  dwarfish  tree  to  one  that  reaches  a  straight, 
sturdy  sixty  feet,  it  can  always  be  recognized  by  its  white  bark,  which  peels  into 
thin,  papery  layers.  This  may  be  worked  into  fancy  objects,  such  as  baskets. 


^^2  ]  Trees  and  How  to  Know  Them 

nowadays,  unlike  the  Indians  and  early  American  settlers,  who 
used  birch  bark  freely  to  make  canoes  and  a  variety  of  receptacles. 

In  the  young  birches  the  bark  is  smooth  and  peels  easily.  As  the 
tree  ages,  the  outer  bark  rolls  back  in  irregular,  frayed  sheets,  and 
the  black  lower  trunk  develops  deep  fissures.  Aside  from  the 
characteristic  bark,  the  paper  birch  is  distinguished  by  its  slender 
trunk  and  an  open  crown  with  small  branches  and  a  quantity  of 
flexible  twigs. 

In  April  or  May  you  may  find  it  interesting  to  watch  for  brown, 
slender  tassel  ends  on  the  twigs.  (These  are  the  male  flowers.)  A 
short  distance  back  from  them  are  the  short,  greenish  female 
cones.  By  fall  these  have  become  loose,  conelike  fruit.  You  will 
usually  find  the  paper  birch  growing  among  white  or  red  pine, 
spruce,  and  aspen. 

The  Gray  and  Yellow  Birches:  Gray  birch  is  much  like  paper 
birch,  as  it  also  has  chalky  white  bark;  but  it  does  not  peel  off 
readily,  and  it  has  short  thick  horizontal  lines.  You  can  easily 
recognize  the  yellow  birch  by  the  lustrous  silvery  yellow  bark  on 
young  trunks  and  on  the  limbs.  Bark  on  older  trees  peels  into  thin 
papery  strips.  Yellow  birch  is  usually  associated  with  maple, 
beech,  ash,  and  red  and  white  pine. 

The  Cherry  Birch:  The  cherry  birch  (also  called  black  birch) 
provides  furniture  manufacturers  with  an  excellent  wood  just  as 
nard  as  mahogany.  Before  the  days  of  synthetics,  an  oil  was  ex- 
tracted from  it  that  was  widely  used  to  flavor  candy  and  medicines. 
Though  this  oil  is  rarely  used  nowadays,  children  still  love  to 
chew  the  bark  of  tender  young  branches  and  twigs.  Another 
product  of  the  cherry  birch  in  bygone  days  was  birch  beer,  made 
from  the  tree's  sap. 

Horse-Chestn UTS— Imported  from  Abroad 

It  is  almost  impossible  to  find  an  American  chestnut  tree, 

for  it  has  been  practically  wiped  out  by  the  chestnut  blight— a 

parasitic  fungus  that  lives  on  its  bark.  Throughout  our  country 

this  tree  has  virtually  been  replaced  by  a  popular  ornamental

species  imported  from  Europe  and  Asia,  known  as  the  horse- 
chestnut.  Because  of  the  similarity  in  names,  many  people  connect 
this  tree  with  the  vanishing  chestnut.  However,  the  two  are  not 
related.  The  nuts  of  the  horse-chestnut,  far  from  being  deliciously 
sweet,  are  so  bitter  that  even  squirrels  shun  them. 

It  is  claimed  that  the  seeds  of  the  horse-chestnut  were  used  long 
ago  as  medicine  for  horses— hence  the  tree's  name.  When  the 
green  prickly  balls  encasing  the  fruit  open  in  the  fall,  the  highly 


THE  LUXURIANT  FOLIAGE  OF  THE  HORSE-CHESTNUT 

This  favorite  shade  tree  carries  a  suggestion  of  tropical  growth  In  the  size  and 
profusion  of  its  leaves  and  its  showy  flower  clusters.  Now  a  favorite  American 
tree,  it  was  originally  found  in  Balkan  countries  and  introduced  int«  England 
before  reaching  our  shores.  Though  inedible  and  despised  even  by  squirrels,  this 
tree's  shiny  rich  brown  nuts  are  prized  by  children. 


364  ]  Trees  and  How  to  Know  Them 

polished  reddish-brown  nuts  become  the  prized  treasures  of  chil- 
dren. Designs  can  be  carved  on  these  nuts,  and  if  they  are  hol- 
lowed out  they  can  be  turned  into  pipes,  baskets,  and  other  toys. 
Even  when  they  are  put  to  no  use  whatever,  they  have  a  tremen- 
dous appeal  and  are  hoarded  by  boys  and  girls  as  if  they  were 
precious,  hard-earned  legal  tender. 

In  June  and  July  you  find  the  horse-chestnut  tree  at  its  loveliest; 
showy  white  flower  clusters  from  six  to  twelve  inches  high  appear 
then  and  the  leaves  are  fully  developed.  Its  leaves  suggest  tropical 
foliage  in  their  size  and  luxuriance,  for  leaflets  from  five  to  seven 
inches  long  are  grouped  together  like  a  palm  with  six  or  seven 
fingers.  Its  bark  is  dark  brown,  with  deep  furrows  and  scaly  ridges. 

Another  imported  tree  furnishes  many  of  the  chestnuts  that  we 
now  buy  at  the  market.  It  is  the  Japanese  chestnut,  a  rather 
dwarfed  and  compact  tree  that  stays  free  of  blight  and  is  excellent 
for  orchard  growth. 

Ginkgos— Admirable  for  City  Streets 

City  streets  are  the  place  to  find  ginkgos,  or  maidenhair, 
trees.  This  species,  imported  from  Japan  and  China  as  a  shade 
tree,  is  excellent  for  city  use  because  it  thrives  on  poor  soil  and  is 
not  harmed  by  heat  reflected  from  pavements. 

The  name  "maidenhair"  was  suggested  by  the  fanlike  leaves 
which  are  shaped  like  the  leaflets  of  the  maidenhair  fern.  They 
are  deep  green  and  turn  a  brilliant  yellow.  The  tree  is  naturally 
cone-shaped,  but  as  it  responds  so  well  to  pruning  you  may  see  it 
rounded  or  otherwise  trimmed  to  a  form  suitable  to  narrow  city 
streets.  The  bark  of  the  short  trunk  is  grayish  brown  with  shallow 
furrows. 


The  Cone-Bearing  Evergreens 

Firs  for  Christmas 

The  firs  are  so  closely  associated  with  the  delights  of  Christ- 
mas that  children  are  likely  to  be  particularly  interested  in  these 
trees.  We  cannot  help  admiring  the  symmetrical  form  and  rich 


Trees  and  How  to  Know  Them  [  365 

green  of  the  persistently  clinging  needles  which  make  the  balsam 
fir  the  ideal  evergreen  for  Christmas  decorating. 

This  tree  retains  its  beauty  even  when  it  is  quite  dried  out  after 
many  days  indoors.  Not  so  all  evergreens— the  spruce,  for  example, 
begins  to  shed  its  needles  fairly  soon  after  being  cut,  as  each  needle 
is  attached  to  the  twig  by  a  small  joint.  Boys  and  girls  love  the 
evergreens  for  the  happiness  they  bring  at  Christmas;  and  while 
grown-ups  feel  the  same  way,  they  may  also  appreciate  them  as 
our  major  source  of  paper  and  lumber. 

The  Fir's  Fragrant  Aroma:  People  living  close  to  balsam  firs 
become  so  accustomed  to  their  fragrant  aroma  that  they  are  no 
longer  aware  of  it.  But  city  children  and  their  parents  delight  in 
the  lovely  "Christmasy"  smell  and  sometimes  enjoy  it  the  whole 
year  round  by  using  cushions  stuffed  with  the  fir  needles. 

Canada  Balsam:  These  firs  yield  another  useful  product:  Canada 
balsam,  used  in  making  turpentine.  The  balsam  comes  from  resin 
blisters  under  the  thick,  rich  brown  bark  which  are  a  great  fire 
hazard  for  the  trees.  In  case  of  fire,  the  resin  quickly  turns  the 
whole  tree  into  a  torch. 

Spruces— Once  Used  for  Chewing  Gum 

Our  native  black  spruce  has  a  wide  natural  range  in  North 
America— from  coast  to  coast,  as  far  south  as  West  Virginia  and  as 
far  north  as  Labrador  and  Alaska.  Young  spruces  are  often  used 
as  Christmas  trees,  despite  the  fact  that  they  shed  their  needles 
early  in  a  warm  house;  but  you  do  not  often  see  them  adorning 
landscapes.  As  cultivated  trees  they  are  relatively  short-lived  and 
their  dead  branches  give  them  an  uneven  appearance. 

Children  are  usually  intrigued  to  know  that  spruce  resin  was 
once  an  important  source  of  chewing  gum— now  replaced  by 
chicle  from  the  tropics.  The  Indians  used  spruce  gum  to  water- 
proof their  canoes. 

How  to  Recognize  a  Black  Spruce:  Among  the  distinctive  features 
of  the  black  spruce  are  its  bluish-green,  blunt-tipped   needles

Trees  and  How  to  Know  Them 


(Left)  THE  BALSAM  FIR  MEANS  CHRISTMAS 

To  children  the  beautiful  and  fragrant  balsam  tree  means  Christmas.  Outdoors, 
the  fir,  with  its  straight  trunk  and  graceful,  symmetrical  branches,  adorns  many  a 
landscape  of  Canada  and  the  northern  United  States.  The  balsam  fir  is  particularly 
attractive  in  wintry  surroundings,  when  it  is  effectively  outlined  against  a  snowy 
background.  It  is  not  a  long-lived  tree;  it  seldom  survives  ninety  years. 

(Right)  THE  SPRUCE  AND  ITS  VARIED  FORMS 

There  are  many  kinds  of  spruce  trees.  The  block  spruce,  pictured  above,  varies  its 
shape  according  to  the  natural  forces  with  which  it  has  to  contend.  On  lov/lands 
the  spruce  grows  narrow  and  toll,  on  mountains  you  may  see  dwarfed  firs  no  more 
than  five  feet  tall.  The  cones  of  this  spruce  may  remain  on  the  tree  for  decades. 

averaging  half  an  inch  in  length  and  growing  in  spirals  along  the 
twigs.  New  twigs  are  yellowish  brown  and  covered  with  short 
reddish-brown  hairs.  Tiny  flowers  appear  near  the  top  of  the 
branches  in  May  or  June.  Small,  clustered  grayish-brown  cones 


Trees  and  How  to  Know  Them  [  367 

mature  in  August,  but  they  may  remain  on  the  trees  as  long  as 
twenty  or  thirty  years! 

You  will  find  the  oldest  cones  at  the  base  of  the  branches, 
nearest  the  trunk.  The  straight  mastlike  trunks  of  spruces  are 
covered  with  bark  of  grayish  brown  or  reddish  brown  tinged  with 
gray.  The  bark  is  scaly  rather  than  furrowed. 

The  Norway  Spruce:  While  we  have  other  important  native 
spruces,  it  is  the  one  imported  from  Norway  that  you  are  most 
likely  to  enjoy.  The  Norway  spruce  has  been  planted  for  forests, 
as  an  ornamental  tree,  and  for  farm  windbreaks  in  both  the 
northern  and  western  states.  The  dark  shiny  needles,  each  with 
tiny  white  lines,  point  upward  and  forward,  but  their  bases 
entirely  surround  the  twig.  They  remain  on  the  twig  for  six  or 
seven  years. 

Hemlocks— Useful  and  Ornamental 

While  we  enjoy  this  magnificent  tree  for  its  appearance,  it 
is  more  than  merely  ornamental  as  far  as  many  animals  are  con- 
cerned. Its  dense  foliage  furnishes  valuable  shelter  for  birds  in 
winter,  and  branches  of  young  hemlocks  drooping  to  the  ground 
form  cozy  hideouts  for  mice,  rabbits,  and  other  small  creatures 
during  severe  weather.  And  sometimes  you  may  catch  sight  of 
squirrels  feasting  on  the  seeds  that  develop  in  the  cones. 

Though  hemlocks  grow  to  massive  proportions,  the  cones  of 
the  eastern  hemlocks  are  among  the  smallest  of  all  tree  cones. 
The  largest  are  about  three-quarters  of  an  inch  long.  They  mature 
in  one  year  and  normally  fall  in  the  spring.  The  cones  of  the 
western  hemlocks  are  nearly  twice  the  size  of  the  eastern  species. 

Three  Centuries  to  Mature:  When  you  look  up  at  the  foliage  of  a 
hemlock,  it  appears  whitish  because  the  needles  are  light  under- 
neath. On  top  they  are  a  rich  dark  green.  Hemlock  branches  are 
seldom  broken  by  snow— they  droop  to  let  it  slide  away.  These 
slow-growing  trees  require  nearly  three  hundred  years  to  reach 
maturity,  and  often  live  more  than  twice  that  long.  Countless 
seeds  are  formed  each  year  and  sail  away  on  tiny  transparent 


368  2  Trees  and  How  to  Know  Them 

wings,  but  they  reproduce  poorly.  Those  that  find  moist,  shady 
conditions  have  the  best  chance  of  survival. 

Useful  Hemlock  Bark:  The  thin  brownish-red  to  purplish  rough 
bark  of  the  eastern  hemlock  is  rich  in  tannin.  Long  ago  the 
Indians  used  this  as  a  curative  for  sores  and  burns.  For  many  years 
it  was  the  basis  of  our  tanning  industry  and  in  some  places  tannin 
is  still  used  for  this  purpose.  It  not  only  preserves  the  leather  but 
gives  it  an  attractive  reddish  tone.  Hemlock  wood  is  used  chiefly 
in  making  pulp  for  wrapping  paper  and  newsprint.  Hemlock 
poison,  notorious  in  ancient  times,  is  not  derived  from  this  tree 
but  from  herbs. 

Pines— Majestic  Trees 

Some  pine  trees  reach  a  height  of  two  hundred  feet— and 
even  more.  An  age  of  two  hundred  years  is  not  unusual,  and  the 
sturdiness  of  pine  wood  makes  it  particularly  suitable  for  the 
masts  of  ships.  And  pines  are  handsome  too.  Branches  of  the  white 
pine  make  especially  graceful  decorations.  If  you  look  at  them 
closely  you  will  see  that  this  graceful  quality  derives  from  their 
length  and  also  from  the  way  that  the  needles  are  attached  to  the 
branches  in  bundles. 

Needles— The  Key  to  Identification:  The  pines  can  generally  be 
distinguished  from  other  evergreens  by  their  longer  needles.  The 
grouping  of  the  needles  provides  a  key  to  the  various  species 
because  the  number  varies  from  one  type  of  pine  to  another.  For 
example,  on  all  true  white  pines  there  are  five  needles  to  a 
bundle;  the  pitch,  red,  and  ponder osa  pines  generally  have  three; 
and  the  pifion  and  lodgepole  pines  have  needles  grouped  in  pairs. 
White  pine  needles  are  long,  soft  and  pliable;  those  of  the  pitch 
pine  are  stiff  and  coarse. 

The  shape  of  pine  needles  is  such  that  the  wind  blowing 
through  them  makes  the  soft  sighing  sound  that  we  like  to  fancy 
as  whispering.  The  "whispering  pines"  and  other  cone-bearing 
evergreens  were  growing  on  earth  long  before  the  more  modem 
type  of  tree— the  deciduous  or  "leaf-dropping"  kind,  which  sheds

(UU)  THE  STUBBORN  HEMLOCK 

The  needles  of  the  eastern  (or  Canadian)  hemlock,  pictured  here,  are  flat,  but  the 
needles  of  some  hemlocks  are  angular.  This  tree  likes  mountains  and  the  shady 
north  sides  of  hills.  The  great  rocks  that  may  abound  in  such  locations  are  no 
handicap;  the  hemlock's  roots  straddle  them  when  necessary,  and  in  time  crack  them 
apart!   This   pyramid-shaped   tree   may   grow   to   a    height  of  one   hundred    feet. 

(Right)  THE  MAJESTIC  WHITE  PINE 

This  magnificent  tree  sometimes  reaches  a  height  of  two  hundred  feet  and  may 
live  two  hundred  years  or  more.  It  is  very  easy  to  identify  by  its  needles,  which 
are  bluish  green,  from  three  to  five  inches  long,  and  grow  in  groups  of  five.  The 
cones  ore  from  four  to  eight  inches  long  and  droop  gracefully.

of  retaining  their  needle-like  leaves  all  year  round. 

Pine  Cones:  Boys  and  girls  enjoy  gathering  the  cones  of  ever- 
greens. Some  of  these  cones  are  splendid  collector's  pieces.  Small 


g^o  ]  Trees  and  How  to  Know  Them 

ones  may  be  painted  or  used  in  natural  color  for  Christmas  trim- 
mings; larger  cones,  such  as  those  of  the  western  sugar  pine,  which 
weigh  a  pound  or  more,  are  spectacular  items  for  nature  collec- 
tions. 

Pine  cones,  which  develop  from  small  pistillate  flowers,  require 
two  years  to  mature.  In  May  and  June  you  can  see  the  bright 
pink  flowers  of  white  pine  growing  near  the  tips  of  new  twigs. 
On  the  new  shoots  of  lower  branches,  yellow  staminate  conelike 
blossoms  appear  and  produce  quantities  of  pollen.  Soon  after 
this  pollen  has  been  carried  off  by  the  wind,  these  blossoms  wither 
and  fall;  but  meanwhile  the  pistillate  flowers,  which  have  been 
pollinated,  are  turning  into  cones. 

By  the  end  of  a  season's  growth  the  cones  are  about  an  inch 
long,  green  and  upright.  By  the  second  season  they  are  longer  and 
turn  downward.  By  August  they  have  turned  brown  and  are  from 
Rye  to  eleven  inches  in  length.  If  you  look  at  them  carefully  at 
this  time,  you  will  find  two  little  winged  seeds  beneath  each  scale. 
In  September  the  cone  scales  open  out  and  the  wind  carries  the 
seeds  away— perhaps  as  far  as  a  quarter  of  a  mile. 

Massive  Sequoias— 1'housands  of  Years  Old 
The  likeliest  place  to  find  these  huge  trees  is  in  the  national 
parks  of  California,  though  giant  sequoias  have  been  successfully 
planted  in  other  parts  of  California  and  occasionally  in  parts  of 
the  eastern  United  States  and  Europe. 

The  sequoia  is  the  most  massive,  as  well  as  the  oldest,  of  all 
living  things.  Some  of  the  very  trees  that  stand  majestically  today 
on  the  high  slopes  of  the  Sierras  were  growing  in  the  time  of 
Christ— roughly  two  thousand  years  ago.  Some  sequoias  are  more 
than  three  hundred  feet  high!  These  magnificent  trees  were  named 
in  honor  of  Sequoyah,  a  gifted  Indian  chief  who  invented  an 
alphabet  over  a  hundred  years  ago  for  his  people  of  the  Cherokee 
tribe. 

The  Sequoia's  Foliage  and  Bark:  The  rich  evergreen  foliage  is  in 
the  form  of  scalelike  sharp-pointed  needles  that  overlap  closely 
on  the  branches.  You  can  see  the  tiny  flowers  in  February  or 


Trees  and  How  to  Know  Them  [371 

March.  From  the  seed-producing  flowers  there  develop  yellowish- 
brown,  egg-shaped  cones  between  two  and  three  inches  long. 
These  mature  in  two  years  and  the  seeds  are  blown  away,  but  the 
empty  cones  often  remain  on  the  tree.  Sequoias  are  better  able  to 
resist  fire  than  other  trees  because  their  spongy  red-brown  bark 
is  at  least  twelve  inches  thick— sometimes  as  much  as  twenty-four— 
on  mature  trees. 

The  Towering  Redwood:  The  giant  sequoia  has  a  cousin,  the 
towering  redwood,  which  grows  to  an  even  greater  height— though 
its  girth  is  less  than  that  of  the  sequoia.  The  redwood  gets  its 
name  from  the  straight-grained  red  wood  which  varies  in  tone 
from  light  cherry  to  dark  mahogany.  It  is  a  popular  wood  for 
building.  As  in  the  case  of  the  sequoia,  the  thick,  fibrous  bark 
is  exceptionally  fire-resistant.  It  is  reddish  gray  with  fissures 
running  up  and  down  the  trunk,  giving  it  a  fluted  appearance. 

The  Redwood  Grows  Readily:  Sometimes  one  finds  old  stumps  or 
roots  of  redwood  from  which  vigorous  sprouts  are  growing  into 
sizable  new  trees.  In  this  respect  they  differ  from  the  giant 
sequoias,  which  grow  only  from  seeds.  The  redwood  cones  also 
produce  many  seeds  that  may  germinate  and  become  young  trees. 
The  tree's  readiness  to  sprout  is  emphasized  by  redwood  burls,  the 
large  knots  that  grow  on  the  trunks.  If  you  place  a  burl  in  water, 
it  quickly  produces  sprouts  to  form  an  attractive  "redwood  plant." 


How  to  Mount  Evergreen  Specimens 

Youngsters  can  make  attractive  exhibits  of  evergreens  with 
little  or  no  aid.  You  start  by  finding  a  shallow  cardboard  box 
and  cutting  a  square  out  of  the  lid,  leaving  a  half-inch  margin 
around  the  edge.  Fill  the  box  with  cotton,  right  up  to  the  top. 
Place  the  evergreen  spray  on  this,  removing  just  enough  of  the 
cotton  under  the  stem  so  that  the  spray  will  lie  flat. 

Now  place  a  piece  of  glass  over  the  square  opening  in  the 
lid  and  fasten  it  neatly  with  a  tape  binding.  Put  the  lid  on  the 
box  and  fasten  it  by  inserting  pins  on  all  four  sides.  You  can  of 


372  ]  Trees  and  How  to  Know  Them 

course  decorate  or  paint  the  box  in  advance,  and  the  tape  may  be 
colored  to  provide  an  even  more  handsome  setting. 

Some  Spring  Beauties 

When  we  look  forward  to  flowers  that  bloom  in  the  spring, 
we  usually  have  in  mind  the  small,  shy  blossoms  of  woodlands 
and  meadows.  However,  certain  trees  make  a  gorgeous  if  brief 
display  with  their  flowers.  If  any  of  these  are  within  reasonable 
traveling  distance  of  your  home,  you  will  be  well  rewarded  if 
you  keep  track  of  the  best  time  to  see  them.  There  is  a  great 
delight  in  viewing  the  massed  array  of  their  colors. 

Flowering  Dogwoods 

The  flowering  dogwood  with  its  beautiful  mass  of  showy 
white  flowers  is  among  the  loveliest  of  all  trees.  It  blooms  from 
late  April  to  early  June,  depending  on  the  locality.  The  spec- 
tacular part  of  its  display  is  not  actually  the  flower,  but  four  white 
or  pink  bracts— specialized  leaves  that  look  like  large  petals. 

Your  first  chance  to  see  these  bracts  comes  in  wintertime  when, 
as  purplish-brown  scales,  they  are  wrapped  snugly  about  the  flower 
buds.  In  early  spring  these  scales  grow  rapidly  and  spread  out. 
The  artistic  notch  on  the  tip  of  each  bract  is  telltale  evidence  of 
its  winter  form.  The  true  flowers,  which  are  yellow  green  and 
inconspicuous,  cluster  at  the  base  of  the  four  bracts.  Such  a  cluster 
consists  of  about  twenty  bracts. 

Magnolias 

The  display  put  on  by  tulip  trees  (members  of  the  mag- 
nolia family)  is  another  sight  to  reward  a  journey  to  the  country, 
though  you  may  also  find  them  on  lawns  or  along  city  streets. 
The  large  greenish-yellow  and  orange  tulip-like  flowers  that  give 
the  tree  its  name  show  themselves  among  the  glossy  leaves  of  late 
spring  and  early  summer. 

We  find  the  magnolia  tree  beautifying  many  a  park  and  lawn 
with  its  striking  pink  and  white  flowers.  Scattered  over  forest 
areas  are  seven  other  species  of  magnolia,  all  of  tree  size.  One  of 


Trees  and  How  to  Know  Them  [  373 

these  is  the  hardy  cucumber  tree,  which  produces  bell-shaped  pale 
yellow  or  green  flowers  from  April  to  June.  You  must  look  closely 
to  see  them— their  coloring  is  so  much  like  that  of  the  spring 
foliage  of  the  tree. 

Apple  Blossoms 

The  blossoms  of  apple  and  other  fruit  trees  make  a  lovely 
floral  display.  Children  can  appreciate  the  individual  beauty  of 
an  apple  tree  in  bloom,  if  they  examine  the  cluster  of  blossoms 
that  grows  at  the  tip  of  each  twig.  With  soft  green  leaves  surround- 
ing each  cluster,  the  effect  is  that  of  a  conventional  bouquet.  By 
contrast,  peach  and  cherry  blossoms  grow  along  the  sides  of  the 
branches. 

Though  we  find  five,  six,  or  even  more  blossoms  in  a  cluster 
of  apple  blossoms,  only  one  or  two  of  each  tend  to  develop  into 
fruit.  It  is  interesting  to  examine  an  apple  and  a  blossom  together, 
observing  the  parts  of  the  flower  that  may  still  be  seen  in  the  fruit. 
The  five  scales  at  the  bottom  of  the  apple  are  the  remains  of  the 
calyx  lobes  that  originally  enclosed  the  blossom;  and  within  them 
are  the  dried  and  shrunken  stamens  and  styles. 

You  will  find  many  buds  on  an  apple  tree  branch  that  produce 
only  leaves;  whereas  at  the  side  and  below  the  spur  (where  the 
apple  develops) ,  there  is  a  bud  that  will  continue  the  growth  of 
the  branch.  The  following  year  the  blossom  buds  will  appear  on 
this  new  growth. 

Shrubs— Mostly  Decorative,  Occasionally  Hanufiil 

How  TO  Tell  a  Shrub  from  a  Tree 

It  is  not  easy  to  be  exact  enough  to  satisfy  a  boy  or  girl 
who  wants  to  know  the  difference  between  a  shrub  and  a  tree. 
Both  shrubs  and  trees  are  woody,  perennial  plants.  Trees  are 
generally  much  larger— but  you  may  find  some  shrubs,  such  as  the 
witch  hazel,  almost  rivaling  a  small  dogwood  tree  in  size.  There 
is  a  definite  line  of  cleavage,  however,  in  that  trees  have  a  single 
trunk,  whereas  shrubs  are  divided  into  many  primary  stems  at  the 
ground,  or  near  it.

Witch  Hazel  and  its  Popgun  Seed 

You  can  look  for  witch  hazel  blossoms  long  after  those  of 
other  plants  have  disappeared.  Sometimes  the  witch  hazel  blossoms 
open  in  late  September,  but  more  often  it  is  October  or  November 
before  the  yellow,  starlike  flowers  open.  As  most  flowers  have 
fallen  by  that  time,  the  long-petaled  flowers  are  particularly  effec- 
tive in  enhancing  the  landscape.  If  you  keep  watching  a  bush, 
you  will  see  that  once  the  flower  petals  fall,  the  calyx  forms  a  little 
urn  in  which  a  nut  will  develop. 

At  first  the  small  nut  is  green,  but  later  it  turns  brown.  It  re- 
quires a  year  to  mature.  Then,  if  you  take  it  indoors,  the  heat 
will  soon  cause  the  edges  of  the  seed  cup  to  curl  inward,  shooting 
the  seeds  out  as  it  does  so.  When  this  shooting  device  functions 
out-of-doors,  the  seeds  are  propelled  many  feet  from  the  parent 
bush  to  new  growing  grounds. 

Lovely  Mountain  Laurel 

By  fall  the  flowers  of  mountain  laurel  have  long  since 
died  away,  but  you  still  find  this  lovely  shrub  a  beautiful  part  of 
the  landscape.  The  lustrous  leaves  do  not  die  with  the  onset  of 
cold  weather  but  remain  green  throughout  the  winter.  With  the 
coming  of  spring,  leaves  grow  on  the  new  wood,  arranged  below 
the  clusters  of  flowers  in  formal  bouquet  design.  You  can  easily 
recognize  the  new  wood:  It  is  greenish  and  rough  while  the  older 
wood  is  brownish  red.  Mountain  laurel  is  a  woodland  shrub, 
with  a  special  adaptation  for  rocky  mountain  sides  and  sandy  soil. 

Staghorn  Sumac— Brilliant  Scarlet 

In  open  fields  and  on  hillsides  you  are  likely  to  come  upon 
staghorn  sumac.  This  is  how  you  can  recognize  it:  In  early  fall 
the  leaves  are  usually  the  most  brilliant  scarlet  of  any  on  the 
landscape.  These  leaves  are  of  the  kind  that  has  a  number  of 
separate  blades  attached  to  both  sides  of  the  long  leaf  stalks, 
though  they  are  not  always  set  exactly  opposite  each  other.  The 
number  of  these  blades  varies  from  eleven  to  thirty-one. 


Trees  and  How  to  Know  Them  i  375 

After  the  leaves  have  fallen,  you  can  realize  why  this  sumac  i? 
named  **staghorn"  when  you  see  the  upper  branches  widely  spread 
in  the  form  of  a  stag's  antlers.  In  the  spring  the  new  growths  of 
wood  and  leaf  stems  are  covered  with  fine  hairs,  giving  them  a 
velvety  feel— again  suggestive  of  a  stag's  antlers  "in  velvet." 

By  the  time  summer  has  arrived,  the  sumacs  resemble  giant 
ferns  with  their  long  narrow  leaf  blades  drooping  somewhat  from 
the  mid-rib.  In  June  a  shrub  shows  two  different  kinds  of  blos- 
soms: one,  a  whitish  form  that  bears  the  pollen;  the  other,  a 
reddish  pistillate  flower  that  later  develops  into  the  dark  red 
seed  on  the  upright  fruit  cluster. 

Poison  Sumac 

One  of  the  hazards  of  nature  exploring  is  the  "poison 
sumac,"  which,  when  handled,  sometimes  causes  painful  itching 
and  swelling.  You  may  recognize  this  species  partly  by  its  location 
(swamps  rather  than  sunny  fields);  by  its  smooth-edged  leaves 
(staghorn  sumac  has  sharp-toothed  leaves) ;  and  by  its  fruit  (a 
drooping  arrangement  of  white  berries).  Any  sumac  with  a  red 
fruit  cluster  is  harmless. 

Poison  Ivy  and  Poison  OmL 

Other  oflEenders  that  may  give  us  discomfort  in  the  course 
of  outdoor  exploring  are  poison  ivy  and  poison  oak,  which  belong 
to  the  same  family  as  the  sumacs.  As  in  the  case  of  the  poison 
sumac,  their  foliage  contains  an  oil  that  poisons  the  skin  of  many 
people  who  come  in  contact  with  it.  You  will  find  poison  ivy 
climbing  up  trees  and  over  walls  and  fences.  It  does  so  by  means 
of  rootlets— not  by  tendrils  such  as  vines  use.  The  poison  oak,  on 
the  other  hand,  is  shrubby  in  form. 

Harmless  vines— this  is  especially  true  of  the  Virginia  creeper- 
are  often  mistaken  for  poison  ivy  although  there  are  several  ways 
to  distinguish  the  nonpoisonous  from  the  poisonous  plants.  Poison 
ivy  is  best  identified  by  its  leaflets  which  are  shiny  and  arranged 
in  groups  of  three.  The  Virginia  creeper  leaves  are  grouped  in 
fives  and  are  dull  rather  than  shiny.  When  berries  develop,  those 
of  poison  ivy  are  white  while  the  Virginia  creeper's  are  dark  blue. 


376  ]  Trees  and  How  to  Know  Them 

Relief  for  Poison  Ivy:  A  thorough  washing  with  heavy  suds 
(preferably  yellow  soap)  is  an  old  precaution  if  you  suspect  that 
you  have  been  exposed  to  these  plants.  Several  preparations  are 
available  in  drugstores  to  treat  cases  of  poison  ivy,  in  which  red- 
ness and  burning  of  the  skin  is  followed  by  the  appearance  of 
small  white  blisters.  When  commercial  preparations  were  not  at 
hand,  I  have  used  a  mixture  of  half  a  cup  of  vinegar  and  a  tea- 
spoon of  salt  with  success.  Dabbed  on  frequently,  this  relieves  the 
itch  and  tends  to  dry  up  the  blisters. 

Making  Leaf  Collections 

Children,  as  we  know,  are  avid  collectors;  and  collecting  leaves 
often  provides  a  completely  satisfying  outlet  for  this  instinct.  They 
can  obtain  foliage  of  many  kinds  of  trees  in  late  summer  and  early 
fall  by  simply  picking  the  leaves  off  the  ground.  To  preserve  them, 
place  each  leaf  between  sheets  of  newspaper,  with  several  sheets 
above  and  more  below,  and  with  a  heavy  weight  on  top  of  the  pile. 
In  a  few  days  the  leaf  will  be  dried  out  and  flattened  so  that  it  can 
be  fastened  in  a  scrapbook  with  narrow  strips  of  cellophane  tape. 

How  TO  Make  Spatter  Prints 

Older  boys  and  girls  may  enjoy  the  more  elaborate  process 
of  making  leaf  prints.  There  are  several  methods.  One  of  them 
is  the  "blueprint"  made  like  the  fern  prints  described  on  page 
337.  Possibly  the  simplest  method  is  the  spatter  print,  which  re- 
quires the  use  of  ink,  a  toothbrush,  a  small  piece  of  wire  screen- 
ing (or  a  thin  stick) ,  sheets  of  paper,  and  fresh— not  dried— leaves. 
First  place  the  leaf  on  a  sheet  of  paper  and  pin  it  down  abso- 
lutely flat.  Then  dip  the  toothbrush  into  the  ink,  remove  it  and 
allow  the  surplus  to  drain  back  into  the  bottle.  Now,  working 
from  side  to  side  and  from  top  to  bottom  of  the  paper,  hold  the 
brush  a  few  inches  above  it  and  rub  the  bristles  against  the  wire 
screening  (or  stick)  to  spatter  the  ink.  Scrape  the  bristles  toward 
you  as  this  throws  the  ink  in  the  opposite  direction.  (It  may  be  a 
good  idea  to  have  the  youngster  practice  this  stroke  several  times 
before  trying  it  with  ink.)

INK  SPAHERING 


BLUEPRINT 


PRINTER'S  INK  PRINT 


When  the  whole  surface  of  the  paper  is  covered,  you  can  finally 
remove  the  leaf— and  what  remains  is  a  perfect  outline  of  the  leaf, 
surrounded  by  hundreds  of  little  spatters  of  ink.  You  can  get  inter- 
esting effects  by  varying  the  combination  of  ink  and  paper  colors. 

How  TO  Make  Prints  with  Printer's  Ink 

Leaf  prints  made  with  printer's  ink  have  the  advantage 
over  spatter  prints  that  they  show  not  only  the  outline  of  the  leaf 
but  also  many  of  its  veins.  The  materials  you  need  for  this  third 
process  are:  a  tube  of  printer's  ink  (any  color) ,  a  sheet  of  window 
glass  slightly  larger  than  the  leaves,  a  rubber  roller,  and  several 
sheets  of  paper. 

Roll  out  a  thin  film  of  ink  on  the  surface  of  the  glass.  Next 
place  the  leaf,  with  its  underside  down,  on  this  inked  surface. 
Put  a  piece  of  paper  over  the  leaf  and  work  the  roller  over  it 
several  times.  Now  you  can  discard  the  paper  and  lift  the  leaf 
from  the  ink. 

To  make  your  print,  place  the  leaf,  with  the  inked  side  down, 
on  a  sheet  of  clean  paper.  Place  another  sheet  of  paper  over  it  and 
work  the  roller  back  and  forth  directly  over  the  paper-covered 
leaf.  Now  remove  the  top  paper  and  leaf  and  allow  the  finished 
print  to  dry. 

When  the  youngster  has  made  a  series  of  leaf  prints  or  mounted 
the  actual  leaves,  his  collection  will  mean  a  great  deal  more  to 


378  ]  Trees  and  How  to  Know  Them 

him  if  he  labels  each  leaf  with  the  name  and  a  few  short  notes 
about  the  characteristics  of  the  tree  on  which  it  grew. 

Growing  Trees  At  Home 

Aside  from  the  pleasure  of  observing  trees  in  their  natural 
environment  and  in  decorative  landscapes,  it  is  also  fun  to  watch 
them  start  growing  from  seed.  It  is  far  more  difficult  to  get  tree 
seeds  to  grow  than  flower  seeds;  even  under  natural  conditions 
only  one  out  of  thousands  may  develop  into  a  tree.  But  if  you 
keep  certain  facts  in  mind,  you  should  have  a  rewarding  measure 
of  success. 

Among  the  better  seeds  to  try  your  green  thumb  with  are 
acorns,  horse-chestnuts,  sycamore,  and  beech  seeds.  They  germi- 
nate quickly  and,  if  successful,  they  put  forth  their  first  leaves 
the  spring  after  they  are  planted.  You  can  prepare  ground  in 
flowerpots  or  flat,  lightweight  wooden  boxes  such  as  the  ones 
used  for  packing  certain  kinds  of  cheese.  If  you  use  the  box,  make 
several  drainage  holes  in  the  bottom  and  cover  them  with  broken 
bits  of  pottery,  rounded  sides  up,  so  that  the  holes  will  not  become 
clogged. 

Now  put  a  layer  of  pebbles  over  the  bottom  of  the  box  or  pot, 
followed  by  garden  soil  or  sand,  mixed  half  and  half,  until  the  box 
is  filled  to  within  half  an  inch  from  the  top— and  press  down 
firmly.  Plant  the  seeds,  place  a  light  covering  of  soil  over  them, 
and  press  the  soil  down  again.  (Such  seeds  as  acorns  and  chestnuts 
should  be  soaked  in  water  for  two  days  before  planting.) 

Keep  your  "tree  garden"  very  close  to  a  window  which  admits 
plenty  of  sunshine.  The  soil,  which  should  be  kept  moist  but 
never  wet,  is  best  watered  with  a  bulb  spray  or  sprinkler.  Until 
the  seeds  sprout,  it  is  helpful  to  cover  the  top  with  a  pane  of  glass, 
thus  preventing  the  surface  from  drying  out. 

You  can  keep  small  trees  in  pots  for  years.  They  remain  dwarfed 
and  do  not  flower,  but  otherwise  they  are  as  interesting  as  forest 
trees.  If  you  have  land  with  space  for  more  trees,  it  is  naturally  a 
thrilling  experience  for  a  child  to  transplant  one  of  the  seedlings 


Trees  and  How  to  Know  Them  [  379 

in  its  second  year  to  the  out-of-doors,  where  it  may  soon  out- 
distance him  in  growth! 

Seeds  of  fruit  trees  are  almost  always  available.  Those  of  the 
orange,  lemon,  and  grapefruit  may  be  planted  thickly  in  shallow 
flowerpots.  They  need  little  attention  and  will  grow  slowly  all 
winter,  producing  attractive  green  decorations.  Apple,  peach, 
cherry,  and  plum  seeds  should  be  mixed  with  dampened  peat 
moss,  placed  in  a  jar  and  put  in  the  refrigerator  for  some  seven 
or  eight  weeks.  Once  a  week  thereafter,  look  at  the  seeds  and 
turn  them  a  little  in  their  mossy  bed.  As  soon  as  they  start  to 
sprout,  take  them  out  and  plant  them  as  you  would  other  tree 
seeds. 


CHAPTER 


2  Our  Earth  and  Its 
Fellow  Planets 


E  HAVE  NOTHING  ON  EARTH  SO  SublimC  aS  the 

star-filled  night  sky.  We  gaze  in  wonder- 
ment at  this  vast  and  mysteriously  ordered  universe  where  a 
million  miles  is  a  short  distance  and  where  each  of  the  countless 
stars  moves  in  its  own  sphere  without  disturbing  other  heavenly 
bodies.  Who,  looking  heavenward,  can  fail  to  feel  trivial  by 
comparison? 

A  small  child  may  not  share  all  our  adult  feelings  about  this 
miracle  of  the  skies.  Yet  even  to  him  the  night  sky  has  an  irresis- 
tible fascination.  When  a  child  recites  * 'Twinkle,  twinkle,  little 
star,  how  I  wonder  what  you  are,"  he  is  unwittingly  giving  expres- 
sion to  mankind's  old  curiosity  about  what  a  star  is,  and  why  it 
behaves  as  it  does.  But  the  child  can  ask  more  questions  about 
stars  than  does  the  poem.  Why  do  stars  disappear  in  the  daytime? 
What  makes  stars  twinkle?  Why  can't  we  fly  to  them  in  an  air- 
plane? Don't  they  ever  bump  into  each  other?  These  are  questions 
that  many  a  child  has  asked  me. 

Some  of  them  are  quite  easy  to  answer.  We  cannot  see  stars  in 
the  daytime  because  the  brilliant  light  of  the  sun  blots  them  out. 
A  youngster  can  understand  this  more  easily  when  he  looks  at 
the  night  sky  from  a  brightly  lit  city  and  finds  how  dim  the  stars 
seem— and  then  sees  their  brightness  from  dark  country  fields. 

380 


Our  Earth  and  Its  Fellow  Planets  [  381 

When  the  sun  is  overhead,  every  bit  of  air  and  dust  catches  its 
light  and  scatters  it.  Thus  in  the  daytime  the  air  is  brighter  than 
the  starlight  and  prevents  it  from  shining  through  to  us. 

Stars  appear  to  twinkle  because  we  see  their  light  through  an 
unsteady  atmosphere.  The  fact  that  there  are  no  collisions  of 
heavenly  bodies  is  explained  by  the  force  of  gravitation,  which 
makes  the  stars,  planets,  and  moons  move  around  each  other  in 
fixed  paths,  or  "orbits."  They  pull  and  tug  at  their  neighbors,  but 
the  net  effect  is  to  hold  all  in  place  rather  than  pull  them  off 
course. 

We  cannot  fly  to  the  stars— though  we  sometimes  feel  we  can 
reach  up  and  almost  touch  them— because  they  are  really  millions 
of  miles  away.  Up  to  now  no  one  has  penetrated  beyond  the  mere 
six  miles  of  air  that  surround  our  earth. 

Things  Are  Not  What  They  Seem 

The  youngster  who  observes  the  heavens  appears  to  be 
easily  learning  a  number  of  facts.  He  watches  the  sun  rise  in  the 
east  and  move  across  the  sky  until  it  sinks  in  the  west.  He  sees 
the  moon  gradually  disappear  each  month,  then  gradually  return 
to  view.  When  he  can  see  it,  he  knows  it  rises  and  sets,  as  the  sun 
does.  He  may  notice  that  the  stars,  too,  seem  to  travel  from  east 
to  west  across  the  sky. 

But  these  are  apparent  happenings.  Our  children  have  the 
benefit  of  centuries  of  study  by  people  who  questioned  what  their 
eyes  perceived;  and  before  a  child  is  ten,  he  usually  begins  to 
learn  at  school  some  of  the  facts  discovered  by  the  astronomers. 
He  is  taught  that  much  of  what  appears  to  be  the  behavior  of  the 
heavenly  bodies  is  actually  the  result  of  our  earth  turning  on  its 
axis  and  revolving  around  the  sun;  and  that  the  moon  is  a  sphere 
that  reflects  the  light  of  the  sun  and  revolves  around  the  earth  in  a 
period  of  about  twenty-nine  days. 

Yet,  even  while  they  are  learning,  today's  children  are  being 
exposed  to  a  new  type  of  fantasy  that  is  likely  to  become  confusing 
even  to  parents.  Science  fiction  and  television  depict  people  racing 
in  rocketships  from  one  planet  to  another;  they  describe  distant 


382  ]  Our  Earth  and  Its  Fellow  Planets 

planets  inhabited  by  humans,  and  present  "new"  planets  to 
explore. 

The  imaginative  child  who  accepts  and  thrills  to  this  fantasy  is 
reassured  to  learn  that  at  least  some  of  it  may  become  reality.  For, 
since  scientists  have  learned  how  to  use  the  energy  inside  the 
atom,  they  seriously  predict  that  atomic-energy-propelled  rocket- 
ships  may  in  due  course  be  sent  to  the  moon.  So,  what  only  a  few 
years  ago  would  have  been  regarded  as  completely  fantastic  is 
today  given  serious  consideration. 

Yet  these  fanciful  facts  are  so  intermingled  with  out-and-out 
fantasy  in  young  minds  that  we  are  actually  bringing  our  children 
down  to  earth— in  more  than  one  sense!— when  we  tell  them  the 
truth,  as  we  know  it  today,  about  planets  and  stars. 

Looking  at  the  Sky 

Though  the  people  of  long  ago  watched  the  skies  closely 
and  made  keen  observations,  they  could  not  understand  many 
things  because  they  assumed  that  the  earth  stood  still  while  the 
planets  and  stars  moved  around  it.  Only  about  350  years  ago  the 
great  Polish  astronomer.  Copernicus  announced  his  startling  hypo- 
thesis: The  movements  of  the  planets  became  understandable  if 
the  earth  was  a  planet  and  if  all  the  planets  revolved  about  the 
sun.  Copernicus  added  that  the  earth  also  turns  on  its  axis  once  a 
day.  Thus,  while  we  are  apparently  watching  heavenly  bodies 
move  from  east  to  west,  we  are  instead  seeing  the  effects  of  the 
earth  whirling  eastward  on  its  axis. 

Galaxies  and  More  Galaxies:  We  call  the  earth  and  its  eight  fellow 
planets  that  travel  around  the  sun,  the  "solar  system."  Beyond 
our  solar  system— a  seemingly  endless  distance  beyond  it— there  are 
billions  of  stars  I  All  these  heavenly  bodies  are  a  part  of  our 
universe,  or  galaxy.  At  one  time,  universe  (meaning  "everything 
there  is,  combined  into  one")  seemed  a  suitable  word  to  use  for 
our  galaxy;  but,  as  exploration  of  the  heavens  continued,  astrono- 
mers found  that  our  universe  was  not  "everything."  Many  other 
galaxies  of  stars  are  scattered  throughout  the  endless  space  that 
surrounds  our  own  galaxy!

What  Telescopes  Tell  Us:  Powerful  modern  telescopes  reach  out 
across  hundreds  of  millions  of  light-years  to  penetrate  some  of 
these  distant  galaxies.  (A  light-year  represents  the  distance  that 
can  be  covered  by  light  in  a  year's  time:  6,000,000,000,000  miles!) 
But  even  the  comparatively  "close"  stars  of  our  own  universe  are 
so  far  away  that  they  appear  as  mere  points  of  light.  Our  most 
powerful  telescopes  make  these  stars  appear  brighter,  but  with  no 
more  defined  form  than  when  we  observed  them  with  the  naked 
eye.

OUR  PLANET  NEIGHBORS  VARY  GREATLY  IN  SIZE 

The  earth  is  neither  the  largest  nor  the  smallest  of  the  planets.  From  Jupiter, 
the  largest,  with  a  diameter  of  eighty-seven  thousand  miles,  to  Mercury  with  o 
diameter  of  only  three  thousand  miles,  there  are  remarkable  differences  among 
the  members  of  the  sun's  family.  However,  all  move  around  the  sun  in  the  same 
direction.  A  year  on  any  planet  is  the  time  it  takes  that  planet  to  moke  a  complete 
revolution  around  the  sun.  The  planets  are  dwarfs,  compared  to  the  sun,  with  its 
864,000-mile  diameter.  The  sun,  a  ball  of  flaming  gas,  is  not  a  planet  but  a  star. 


On  the  other  hand,  when  we  look  at  any  of  the  planets  (except 
Pluto,  the  most  distant  one)  through  a  large  telescope,  they  appear 
as  round  disks,  similar  to  our  moon.  Jupiter,  largest  of  the  planets, 
which  is  hundreds  of  millions  of  miles  distant  from  the  earth, 
needs  to  be  magnified  only  fifty  times  to  appear  as  large  as  the 
moon.

Telescopes  for  Everyday  Use 

If  your  family  becomes  seriously  interested  in  stargazing,  you 
may  consider  a  telescope  of  your  own  a  worth-while  investment. 
Either  of  the  two  types  that  are  used  by  the  great  observatories 
devoted  to  astronomy,  can  be  obtained  in  vastly  reduced  size. 

Refractor  Telescopes 

The  kind  that  looks  as  you  might  expect  it  to— that  is, 
resembling  a  long  spyglass— is  known  as  a  refractor,  or  lens,  tele- 
scope. It  is  called  a  "refractor"  because  starlight,  as  it  passes 
through  the  lens,  is  bent  or  refracted  by  the  curved  surface  of  the 
glass,  then  brought  together  at  the  focus. 

Reflector  Telescopes 

The  other  type  is  a  "reflector"  or  mirror  telescope.  It  brings 
the  light  from  the  stars  to  a  focus  by  reflection  from  a  mirror, 
which  is  not  flat  like  an  ordinary  mirror  but  slopes  gradually 
towards  its  center.  The  world-famous  telescope  on  Mt.  Palomar 
in  California  is  a  reflector. 

Each  type,  refractor  and  reflector,  has  its  advantages  for  the 
professional  astronomer,  but  on  the  whole  the  refractor  seems 
best  for  a  child.  It  is  less  subject  to  damage  from  inexperienced 
handling  and  as  a  rule  the  stars  are  seen  more  sharply  through  it. 

Choosing  a  Telescope:  If  you  are  buying  a  telescope,  it  is  wise  to 
choose  a  small  one  with  a  good  lens  and  a  tripod  (mounting) , 
rather  than  a  large  one  without  these  assets.  A  mounting  that  is 
not  firm  will  show  you  "dancing  stars"  as  you  look  through  it. 
Equipment  of  this  kind  may  require  an  investment  of  more  than  a 
hundred  dollars;  however,  you  may  find  satisfactory  an  extension 
type  of  telescope  that  is  held  to  the  eye.  The  cost  of  such  an  instru- 
ment is  less  than  half  that  of  a  mounted  telescope. 

In  many  towns  and  cities  groups  of  young  people  interested  in 
the  stars  have  astronomy  clubs.  Belonging  to  such  an  organization 
often  gives  a  child  the  opportunity  to  use  a  telescope  regularly, 
thus  saving  his  family  the  expense  of  investing  in  one.  The  club 


PARASOL  ANT- 
SCIENTIFIC  GARDENER 
This  ant  bearing  a  piece  of  leaf, 
parasol-fashion,  is  not  shading 
itself  from  the  sun  but  is  carrying 
out  an  important  part  of  its  farm 
program.  Parasol  ant  workers  cut 
leaves  underground  and  on  them 
plant  fungus  spores  which  pro- 
duce food  for  the  colony.  In 
dense  tropical  forests  a  proces- 
sion of  these  large  ants  may 
extend    a   good    part   of    a    mile.

THE   BEAUTIFUL,  USEFUL,  AND  ALARMING  DRAGONFLY 

Many  people  regard  this  handsome  insect  (note  i's  exquisite  tiansparent  wings)  with 
almost  superstitious  fear.  But  not  only  is  it  harmless  to  man— it  helps  to  keep 
mosquito  pesti  in  check.  Dragonfly  eggs  ore  often    laid  right  in  the   water.

A  MONARCH  BUTTERFLY  IS  BORN 

Behind  the  creation  of  every  butterfly  is  a  fanciful  story.  The  ugly  cater- 
pillar turns  into  a  chrysalis  of  rare  beauty.  The  monarch  chrysalis,  shown 
first  at  the  upper  left,  is  a  jewel  of  gold  and  green,  hanging  from  o 
leaf  or  fence.   It  gets  darker;  after  twelve  days  the  butterfly    emerges. 


A  MONARCH  ON  ITS 
FAVORITE  PERCH 
When  the  butterfly  emerges 
from  the  chrysalis,  its  wings 
are  damp  and  limp,  but  soon 
they  harden  and  the  insect 
becomes  a  sturdy  flier.  The 
monarch  can  sail  in  strong 
breezes  or  light  rainstorms, 
and  is  notable  for  its  long- 
distance migrations.  The  fe- 
males, as  they  travel  north 
in  the  spring,  lay  eggs  on

The  Planets 

"Is  there  much  difiEerence  between  stars  and  planets?"  your  sky- 
minded  youngster  may  ask.

THE   PLANETS  TRAVEL  ABOUT  THE  SUN -OUR  DAYTIME  STAR 

Two  planets  are  closer  to  the  sun  than  is  our  earth;  six  others  are  farther  away, 
rhe  drawing  shows  the  planets  in  the  order  of  their  distance  from  this  great 
blazing  mass.  It  may  be  that  beyond  our  solar  system,  there  are  other  planets 
revolving  about  stars  which  furnish  them  light  and  warmth  as  our  sun  does  for  us. 


386  ]  Our  Earth  and  Its  Fellow  Planets 

There  is,  indeed.  Stars  are  blazing  masses  of  glowing  gas,  like 
our  sun.  We  are  told  that  something  like  two  or  three  billion 
years  ago  a  great  piece  of  our  sun  was  drawn  away  from  the  main 
body  and  separated  into  nine  parts.  The  generally  held  theory  is 
that  the  gravitational  attraction  of  a  passing  star  pulled  away  a 
portion  of  the  sun's  mass,  which  later  broke  up  into  separate  drops. 
Some  of  these  went  much  further  away  from  the  sun  than  others, 
but  all  cooled  into  solid  balls,  and  all— controlled  by  the  sun's  pull 
or  force  of  gravitation— proceeded  to  revolve  about  the  sun.  These 
are  the  planets. 

From  planet  Earth  we  can  see  five  of  the  others— Mercury,  Mars, 
Venus,  Saturn,  and  Jupiter— without  using  a  telescope.  The  re- 
maining three— Uranus,  Neptune,  and  Pluto— are  too  faint  to  be 
seen  with  the  naked  eye. 

How  Planets  Differ  from  Stars 

It  will  help  you  to  distinguish  planets  from  stars  if  you 
keep  several  points  in  mind.  Planets  shine  steadily— they  do  not 
twinkle  as  stars  always  appear  to  do.  This  difference  comes  about 
because  the  beam  of  light  that  radiates  from  a  planet  is  wider  than 
that  from  a  more  distant  star,  and  is  therefore  less  influenced  by 
our  atmosphere.  Also,  the  way  the  planets  move  about  the  sky  is 
different  from  the  movement  of  the  innumerable  stars  that  sur- 
round them. 

Like  stars,  the  planets  appear  first  in  the  east  and  seem  to  travel 
westward;  but  you  will  notice  that  the  position  of  the  stars  with 
relation  to  one  another  remains  constant.  The  position  of  the 
planets  among  the  stars,  however,  is  variable. 

If  you  start  to  keep  track  of  a  planet,  you  will  see  it  change  its 
heavenly  neighbors  week  after  week.  More  than  two  thousand 
years  ago,  the  Greeks  noticed  these  "stars"  that  behaved  differently 
from  the  rest,  and  named  them  planets— in  Greek  this  means 
"wanderers." 

How  TO  Locate  the  Planets 

The  night  sky  may  well  bewilder  parent  and  child  as  they 
first  try  to  distinguish  planets  from  stars,  and  one  star  group  from 


Our  Earth  and  Its  Fellow  Planets  [  387 

another.  Charts  which  indicate  the  positions  of  these  heavenly 
bodies  will  help  you  to  recognize  them  and  also  indicate  where  to 
look  for  them  as  their  positions  change.  You  can  find  sky  charts 
in  many  newspapers  and  in  publications  devoted  to  astronomy. 

When  your  child  has  looked  carefully  at  timely  charts,  he  will 
be  thrilled  as  he  traces  with  you  the  paths  of  the  planets.  Over  a 
period  of  time  he  will  have  the  exciting  experience  of  seeing  them 
travel  along  with  the  stars,  then  seemingly  move  backward—then 
soon  turn  again  and  go  forward  in  their  original  direction. 

Why  the  Earth  is  "Different" 

It  is  quite  natural  for  a  child  to  suppose  that  since  our 
earth  is  one  of  a  group  of  planets,  the  others  are  worlds  just  like 
our  own.  When  he  learns  that  this  is  not  so,  he  will  surely  be 
intensely  curious  about  the  difference  between  the  earth  and  the 
other  planets. 

Is  it  because  the  other  planets  are  too  far  away  from  the  sun— 
or  too  near  it— that  he  could  not  live  on  them?  Some  planets  are 
larger  than  the  earth  (which  has  a  diameter  of  nearly  eight  thou- 
sand miles)  and  others  are  smaller.  Is  the  size  of  a  planet  important 
in  regulating  the  possibility  of  life  on  it? 

Why  Life  is  Possible  on  our  Earth:  Most  scientists  agree  that  p 
combination  of  favorable  factors  makes  our  form  of  life  possible 
on  earth. 

Among  these  are  the  size  and  weight  of  the  materials  of  which 
the  earth  is  made.  They  are  just  right  to  produce  the  gravity  that 
is  needed— not  too  great  to  crush  us  by  our  own  weight,  and  yet 
great  enough  for  the  earth  to  hold  sufficient  atmosphere  to  sustain 
life. 

Another  condition  is  that  we  are  neither  too  close  to,  nor  too 
far  away  from,  the  sun;  and  the  length  of  our  seasons  is  apparently 
stimulating  to  organic  life.  Not  only  are  these  particular  condi- 
tions missing  on  other  planets,  but  they  have  other  conditions 
definitely  unfavorable  to  our  form  of  life. 


388  ]  Our  Earth  and  Its  Fellow  Planets 

As  we  look  at  the  other  planets,  it  appears  that  if  there  is  life 
in  these  other  worlds,  it  must  be  of  a  kind  that  is  beyond  our 
experience  and  understanding. 

Mars— Science-Fiction  Favorite 

Of  all  the  planets,  Mars  is  the  one  most  often  used  by  science- 
fiction  writers  as  the  home  of  a  race  of  people  similar  to  ourselves. 
They  choose  Mars  because  they  have  more  information  on  which 
to  base  their  stories  than  they  have  about  the  other  planets.  It  is 
one  of  our  closest  planetary  neighbors,  and  while  many  of  the 
other  planets  are  hidden  behind  dense  clouds,  the  atmosphere  of 
Mars  is  so  thin  that  we  can  see  through  it  clearly. 

Mars  Through  the  Telescope:  If  you  look  at  Mars  through  a  tele- 
scope it  appears  mostly  orange  in  color;  but  patches  of  other  colors 
show,  too.  At  the  top,  or  at  the  bottom,  of  the  disk  (and  some- 
times at  both  locations  at  once) ,  there  is  a  great  patch  of  white. 
These  patches  are  apparently  fields  of  snow  and  ice  which  we  call 
polar  caps.  When  the  northern  half  of  the  planet's  axis  begins  to 
tilt  toward  the  sun,  the  northern  polar  cap  begins  to  grow  smaller, 
while  the  southern  polar  cap  shows  a  gradual  increase  in  size. 

The  diameter  of  Mars  is  about  4,200  miles— only  about  half  of 
our  earth's. 

The  **Canals"  on  Mars 

The  discovery  of  "canals"  on  Mars  about  seventy-five  years 
ago  quickly  gave  rise  to  the  exciting  idea  that  people  like  our- 
selves live  on  that  planet.  But  actually  the  canal  theory  started 
from  a  misunderstanding!  When  an  Italian  astronomer,  Giovanni 
Schiaparelli,  was  observing  Mars  through  his  small  telescope,  he 
saw  on  its  surface  what  looked  like  a  network  of  fine  lines.  He 
noted  them  as  canali,  an  Italian  word  meaning  "channels."  English 
translations  immediately  turned  this  into  "canals"— a  word  we  use 
for  artificial  waterways  made  by  human  beings. 

Ever  since  that  time  the  canals  have  been  a  subject  for  debate; 
the  astronomers  have  not  been  able  to  agree  on  their  description 
of  the  "canals,"  and  some  even  refuse  to  recognize  anything  that 


Our  Earth  and  Its  Fellow  Planets  [  389 

even  resembles  channels.  Some  scientists  believe  they  are  volcanic 
cracks;  others  say  they  are  watercourses;  still  others  hold  they  are 
formed  by  vegetation. 

Life  on  Mars:  Today  the  idea  that  there  is  human  life  on  Mars 
is  generally  discredited  but  we  are  fairly  sure  that  plant  life,  at 
least,  does  exist  there.  An  analysis  of  the  planet's  atmosphere 
reveals  similarities  to  our  own— including  free  oxygen.  This  indi- 
cates that  plant  life  is  possible,  and  looking  through  a  telescope 
we  see  greenish  markings  (probably  caused  by  vegetation)  that 
appear  to  move  across  the  face  of  Mars. 

The  motion  that  we  see  is  due  to  the  fact  that  Mars  is  turning 
on  its  axis— just  as  the  earth  does.  And  because  the  axis  of  Mars 
is  tilted  just  about  as  much  as  ours,  we  conclude  that  Mars  must 
have  seasons  like  our  own.  But  it  takes  Mars  nearly  two  years  to 
complete  a  journey  around  the  sun;  its  seasons  are  therefore  much 
longer  than  ours,  and  its  "year"  is  nearly  twice  as  long  as  one  of 
our  years. 

Mars  WrrHour  a  Telescope 

When  you  look  at  the  sky  unaided  by  a  telescope,  Mars 
appears  reddish— in  contrast  to  the  blue  of  other  planets  and  stars. 
It  was  this  reddish  tinge  that  led  the  ancients  to  associate  the 
planet  with  their  god  of  war.  Sometimes  Mars  is  brilliant,  at  other 
times  dim.  The  variation  is  caused  by  its  changing  distance  from 
the  earth  and  by  its  distance  from  the  sun;  Mars  shines  by  reflected 
sunlight. 

Sometimes  Mars  is  250  million  miles  away  from  the  earth,  and 
sometimes  as  close  as  thirty-six  million  miles.  When  the  earth  is 
between  Mars  and  the  sun.  Mars  is  at  its  brightest  as  viewed  from 
the  earth.  When  Mars  is  on  the  opposite  side  of  the  sun  from  us. 
Mars  is  very  dim. 

Martian  Invasion 

Many  years  ago  H.  G.  Wells  wrote  a  work  called  The  War 
of  the  Worlds,  in  which  he  described  with  great  imaginative  skill 
a  Martian  invasion  of  our  planet.  When  a  dramatized  version  of 


390  ]  Our  Earth  and  Its  Fellow  Planets 

this  story  was  broadcast  on  a  Sunday  evening  in  1938,  the  narra- 
tion was  so  "realistic"  that  great  numbers  of  people  were  caught 
in  the  unreasoning  grip  of  hysteria.  The  popular  reaction  to  this 
broadcast  is  the  most  convincing  proof  that  scientific  knowledge 
of  the  planets  is  not  very  widespread.  Their  distance  is  so  great, 
of  course,  that  no  object  could  proceed  from  them  toward  our 
planet  without  its  movements  being  noticed  long  in  advance  of  its 
arrival. 

Mercury— Submerged  by  the  Sun's  Brilliance 

Though  Mars  is  probably  our  most  frequently  discussed  planet 
neighbor,  Venus  and  Mercury  are  also  reasonably  close— close,  that 
is,  in  comparison  to  the  other  five  remaining  planets.  Together 
with  Earth  and  Mars,  they  are  sometimes  called  the  "terrestrial 
planets."  All  are  made  up  of  solid,  fairly  heavy  material.  All  are 
roughly  comparable  in  size,  and  all  rotate  on  their  axis  at  moderate 
or  slow  speed. 

Life  is  Impossible  on  Mercury 

The  smallest  member  of  the  sun*s  "family,"  Mercury  is  also 
closest  to  the  sun.  Because  of  its  small  size  and  slight  mass  (it  is 
only  three  thousand  miles  in  diameter  and  the  earth  has  twenty- 
five  times  as  much  mass) ,  the  attraction  of  gravity  on  its  surface 
is  not  enough  to  retain  an  atmosphere.  And  because  of  its  nearness 
to  the  sun.  Mercury's  surface  is  hot.  The  heat  and  lack  of  atmos- 
phere make  life  impossible. 

When  Mercury  is  Visible 

Submerged  by  the  sun's  brilliance.  Mercury  is  generally 
invisible  to  us.  During  the  year  there  are  only  six  periods  of  two 
weeks'  duration  when  we  can  see  it  clearly,  shining  with  a  white 
light.  These  are  the  times  when  it  is  farthest,  east  or  west,  from 
the  sun  as  seen  from  the  earth.  When  it  is  far  to  the  east  of  the 
sun.  Mercury  sets  soon  after  the  sun.  We  then  see  it  in  the  west, 
and  know  it  as  the  "evening  star."  About  two  months  later,  when 
Mercury  is  farthest  to  the  west  of  the  sun,  it  rises  in  the  east  a 


Our  Earth  and  Its  Fellow  Planets  [391 

while  before  the  sun,  and  we  know  it  as  the  "morning  star." 
Mercury  requires  eighty-eight  days  to  complete  its  trip  around 
the  sun. 

Venus— Most  Brilliant  of  the  Planets 

This  planet,  named  by  the  ancients  for  their  goddess  of  beauty, 
is  also  close  to  the  sun,  but  it  shines  with  remarkable  brilliance.  In 
fact,  aside  from  the  moon,  Venus  is  the  brightest  object  in  the 
night  sky.  It  is  invisible  for  certain  periods,  like  Mercury;  but 
these  periods  of  invisibility  are  far  less  frequent  than  Mercury's. 
We  can  hope  to  see  Venus  about  sunset  or  dawn,  and  occasionally 
we  can  see  it,  with  the  naked  eye,  in  broad  daylight. 

The  Atmosphere  of  Venus 

Venus  has  an  atmosphere,  and  in  fact  it  is  completely 
covered  by  dense  white  clouds— one  reason  for  its  brilliance,  as 
the  clouds  reflect  light.  Unfortunately  the  clouds  hide  all  fixed 
points  on  the  planet,  so  we  do  not  know  what  its  surface  is  like. 
Astronomers  have  not  detected  oxygen  and  water  vapor  in  the 
upper  atmosphere  of  Venus— a  fact  which  leads  us  to  conclude 
that  life  does  not  exist  there.  However,  we  do  not  know  what 
conditions  exist  below  the  heavy  surrounding  curtain  of  clouds. 
With  a  small  telescope  you  can  watch  Venus  go  through  phases 
similar  to  those  of  the  moon.  When  it  is  nearest  to  the  earth  it 
appears  as  a  crescent;  when  the  planet  is  farthest  from  the  earth 
it  is  "full." 

Earth— Just  Another  Planet 

With  solid  ground  under  his  feet,  and  firmly  rooted  trees, 
solidly  constructed  buildings,  and  many  other  stationary  objects 
all  about  him,  a  child  finds  it  difficult  to  think  of  our  earth  as  a 
heavenly  body  moving  freely  through  space,  just  like  the  other 
planets.  Probably  the  most  convincing  evidence  you  can  offer  the 
youngster  to  show  that  we  do  live  on  a  moving  planet  is  to  cite 
our  change  of  seasons  and  alternating  periods  of  light  and 
darkness.

Our  Earth  and  Its  Fellow  Planets 


That  the  sun  stands  still  (aside  from  rotating  on  its  axis)  has 
been  known  since  the  time  of  the  astronomer  Copernicus.  Con- 
sequently the  earth  must  be  moving,  or  we  would  have  no  change 
from  winter  to  summer  or  from  day  to  night.  The  earth  and  all 
the  other  planets  travel  around  the  sun  and,  at  the  same  time, 
turn,  or  spin,  on  an  axis  (the  imaginary  line  that  connects  the 
North  Pole  with  the  South  Pole,  in  the  case  of  the  earth) . 

Night  and  Day 

A  good  way  to  give  a  child  a  clear  picture  of  some  of  the 
causes  and  effects  of  the  earth's  motions  is  to  have  a  lamp  represent 
the  sun.  An  inexpensive  globe  may  be  bought  at  many  five-and- 
ten-cent  stores,  and  as  you  rotate  the  globe  and  make  it  revolve 
around  the  lamp,  the  youngster  can  see  how  light  from  the  sun 
varies  at  different  parts  of  the  earth. 

As  the  Earth  Whirls  Through  Space:  If  we  could  stand  out  in 
space  to  watch  our  earth,  as  we  can  observe  the  lamp  and  globe  in 
our  room,  we  would  see  that  the  earth  makes  one  complete  turn 
on  its  axis  every  twenty-four  hours.  This  may  seem  very  slow,  but 
at  its  widest  part— around  the  equator— it  is  whirling  at  a  rate  of 


DAY  CHANGES  TO  NIGHT  AS  THE  EARTH  TURNS  ON  ITS  AXIS 
As  the  earth  rotates,  some  of  it  always  faces  the  sun  and  has  daylight.  As  rotation 
continues,  this  portion  is  gradually  turned  away  from  the  sun  and  night  descends 
there.  All  the  planets  rotate  in  this  manner,  and  the  length  of  a  day  on  each 
depends  on  the  time  it  takes  to  moke  one  complete  turn  on  its  axis.  A  day  on  Mars 
is  thirty-seven  minutes  longer  than  our  twenty-four-hour  day.  Jupiter's  day  is 
less  than  ten  hours,  while  one  day  on  Mercury  equals  eighty-eight  of  our  days! 


Our  Earth  and  Its  Fellow  Planets  [  393 

more  than  a  thousand  miles  an  hourl  At  places  north  and  south 
of  the  equator  the  rate  is  not  quite  so  fast.  The  rotating  speed  at 
San  Francisco,  Chicago,  and  New  York  is  750  miles  an  hour. 

Sunrise,  Noon,  and  Night:  Just  as  our  lamp  illumines  only  half 
the  globe  at  a  time,  so  the  light  of  the  sun  shines  on  only  half  the 
earth  at  a  time.  This  is  what  gives  us  our  alternation  of  night  and 
day.  As  the  earth  turns  so  that  we  can  see  the  sun  from  our  particu- 
lar spot  on  earth,  we  say  that  "the  sun  is  rising." 

The  earth  continues  to  turn  eastward  and  the  sun  appears  to 
rise  higher  and  higher  in  the  sky.  When  the  sun  is  as  high  as  it 
"can  go,"  we  have  "noon."  After  that  the  sun  seems  to  sink  lower 
and  lower  until  the  earth  has  turned  so  far  that  we  can  no  longer 
see  the  sun  from  our  particular  spot  on  earth.  We  say  that  "the 
sun  has  set."  It  is  now  night  on  our  side  of  the  earth— but  on  the 
other  side  of  the  earth,  day  is  beginning. 

Why  the  Amount  of  Daylight  Varies:  The  path  that  the  sun 
appears  to  follow  in  the  sky  varies  according  to  our  location  on 
the  earth.  If  we  were  at  the  equator,  we  would  find  night  and  day 
of  equal  length  throughout  the  year.  But  the  farther  north  we  are 
from  the  equator,  the  farther  around  to  north  does  the  sun  rise 
and  set  in  summer  (making  for  long  days  and  short  nights) . 

Thus  if  we  travel  far  to  the  north  in  summertime,  we  find  the 
days  still  longer  than  they  are  in  the  United  States.  When  we  get 
as  far  north  as  the  capital  of  Sweden,  for  example,  a  summer  day 
is  nearly  nineteen  hours  long.  Still  farther  north,  beyond  the 
Arctic  Circle,  there  is  a  time  in  midsummer  when  we  would  find 
the  sun  shining  continuously  for  forty-eight  hours! 

In  wintertime,  however,  the  farther  north  we  are  from  the 
equator,  the  farther  to  the  south  does  the  sun  rise  and  set.  This 
produces  short  days  and  long  nights. 

What  causes  these  changing  lengths  of  night  and  days?  The 
earth's  axis  is  tilted  and  always  pointed  in  the  same  direction— 
with  the  North  Pole  toward  the  north  pole  of  the  sky.  There  is  a 
certain  stage  in  the  journey  of  the  earth  around  the  sun  when  our 
North  Pole  is  tipped  farthest  toward  the  sun.  One  result  is  that 


394] 


Our  Earth  and  Its  Fellow  Planets 


sunshine  goes  far  beyond  the  Pole,  making  long  days  (summer) 
on  the  northern  half  of  the  earth.  When  the  earth  reaches  a  differ- 
ent stage  in  its  journey  around  the  sun  so  that  the  North  Pole- 
always  pointing  in  the  same  direction— begins  to  tip  further  and 
further  away  from  the  sun,  daytime  on  the  northern  half  of  the 
earth  grows  shorter:  Winter  is  approaching. 

If  the  earth's  axis  were  not  tilted— if  the  axis  were  straight  up 
and  down  in  relation  to  its  path  around  the  sun,  the  sun  would 
always  appear  directly  over  our  equator,  and  throughout  the  earth 
the  days  and  nights  would  be  of  equal  length. 

Why  We  Have  Changing  Seasons 

The  slant  of  the  sun's  rays  affects  the  earth's  seasons.  In 
the  United  States  the  rays  are  most  nearly  vertical— coming  almost 


SEASONS  CHANGE  AS  THE  EARTH  TRAVELS  AROUND  THE  SUN 
The  variation  in  the  way  the  sun's  rays  reach  us  causes  the  seasons  of  spring, 
summer,  autumn  and  winter;  and  the  variation  results  because  the  earth's  axis  is 
not  exactly  perpendicular  to  its  path  around  the  sun,  but  is  tipped  toward  the 
north.  The  axis  always  points  in  the  same  direction,  but  the  fact  that  it  is  tipped 
causes  the  North  Pofe  to  point  away  f'rom  the  sun  during  our  winter  and  toward 
the  sun  in  summer.  We  receive  only  one  two-billionth  of  the  sun's  energy. 


Our  Earth  and  Its  Fellow  Planets  [  395 

straight  down— on  June  21  (beginning  of  summer).  On  December 
2 1  (beginning  of  winter)  they  come  to  us  on  more  of  a  slant  than 
at  any  other  time. 

We  notice,  however,  that  we  have  our  hottest  weather  in  July 
and  August,  and  our  coldest  in  January  and  February.  This  lag  is 
explained  by  the  fact  that  the  earth  takes  time  to  grow  warm 
again  after  the  cold  of  winter,  and  to  become  fully  cooled  oflE 
after  the  accumulation  of  summer  heat. 

Winter  in  June:  On  the  day  that  summer  begins  in  the  Northern 
Hemisphere,  winter  begins  in  the  Southern  Hemisphere;  at  the 
stage  of  the  earth's  journey  around  the  sun  where  the  North  Pole 
is  tipped  farthest  toward  the  sun,  the  South  Pole  is  tipped  farthest 
away  from  the  sun.  Thus  we  see  that  the  seasons  in  the  Southern 
Hemisphere  are  the  reverse  of  those  in  the  Northern  Hemisphere 
at  the  very  same  time.  This  shows  that  winter  and  summer  are  not 
caused  by  the  earth  being  farther  away  from,  or  nearer  to,  the  sun. 
It  is  the  tilting  of  the  axis  that  produces  the  changes  of  the  seasons. 

Jupiter— Largest  of  tbe  Planets 

This  planet  is  often  one  of  the  brightest  objects  in  our  night 
sky,  and  this  may  give  us  the  impression  that  it  is  at  least  as  close 
to  the  earth  as  Mars.  The  fact  is  that  Jupiter  is  hundreds  of  mil- 
lions of  miles  further  away  from  us  than  Mars  is;  however,  the 
tremendous  size  of  Jupiter  enables  us  to  see  it  clearly.  It  is  the 
largest  of  all  the  planets  (perhaps  that  is  why  the  ancients  named 
it  for  the  king  of  their  gods) ,  with  a  diameter  about  eleven  times 
that  of  the  earth. 

An  Atmosphere  Thousands  of  Miles  Deep 

With  only  a  small  telescope  you  can  get  a  closer  view  of 
Jupiter,  making  out  soft  shades  of  red,  yellow,  tan,  and  brown 
that  form  bands  across  the  distant  white  planet,  parallel  to  its 
equator.  These  bands  are  actually  clouds,  composed  in  the  main 
of  two  poisonous  gases— ammonia  and  methane.  Their  presence 
rules  out  any  possibility  of  life  as  we  know  it  on  earth.  Scientists 


2g6  ]  Our  Earth  and  Its  Fellow  Planets 

believe  that  the  atmosphere  of  Jupiter  is  thousands  of  miles  deep 
and  that  the  solid  core  of  the  planet  is  comparatively  small. 

Jupiter  Has  Moons 

What  is  possibly  the  most  interesting  feature  of  Jupiter, 
the  procession  of  moons  that  circle  about  the  planet,  cannot  be 
seen  with  the  naked  eye.  There  are  twelve  of  these  moons— four  of 
them  visible  through  powerful  field  glasses.  Looking  at  these  four 
through  a  small  telescope,  you  may  see  them  circling  around 
Jupiter,  first  in  front  of,  then  vanishing  behind,  the  giant  planet. 
It  was  about  350  years  ago  that  the  great  Galileo  discovered  these 
four  moons,  which  are  about  the  size  of  our  own  moon.  They 
were  the  first  moons  ever  seen  that  belonged  to  any  other  planet 
than  the  earth.  The  development  of  more  powerful  telescopes  led 
to  the  discovery  of  eight  smaller  moons  around  Jupiter,  the  most 
recent  one  coming  in  1951. 

Saturn  and  Its  Strange,  Gigantic  Rings 

This  planet,  too,  has  moons,  but  it  has  an  even  more  fascinating 
feature.  Saturn  is  encircled  by  three  strange,  gigantic  rings  that 
whirl  around  it  continually.  These  rings  are  one  of  the  unsolved 
mysteries  of  astronomy.  Why  should  Saturn— but  no  other  planet- 
have  rings? 

The  rings  of  Saturn  are  not  solid— they  are  apparently  made  up 
of  innumerable  tiny  particles,  perhaps  no  larger  than  grains  of 
dust.  These  great  rings  are  probably  not  more  than  ten  miles 
thick— which  is  paper-thin  in  relation  to  its  enormous  diameter. 

Looking  at  Saturn's  Rings 

If  we  view  Saturn  through  a  small  telescope,  we  see  the 
rings  as  a  single  flattened  object.  However,  a  more  powerful  instru- 
ment reveals  all  three  of  them,  one  inside  the  other.  The  inner- 
most ring  is  very  faint;  the  middle  one  is  the  brightest.  They  are 
inclined  at  an  angle  that  is  unchanging,  but,  as  the  planet  moves 
around  the  sun  we  see  them  at  varying  angles  according  to  Saturn's 
position  with  respect  to  the  earth. 


Our  Earth  and  Its  Fellow  Planets  [  397 

Saturn  takes  twenty-nine  and  a  half  of  our  years  to  revolve  about 
the  sun.  Twice  during  that  period  the  rings  are  so  tilted  that  only 
a  narrow  edge  faces  the  earth.  At  that  stage  we  cannot  see  the 
rings  at  all  through  a  small  telescope;  we  succeed  with  a  powerful 
instrument  only  because  of  sunlight  shining  through  the  rings. 
When  they  appear  upward  or  downward,  the  three  rings  are 
distinct. 

It  is  fascinating  to  observe  the  changing  aspects  of  the  rings  as 
the  shadow  of  Saturn  is  thrown  on  them,  and  again  as  the  shadow 
of  the  rings  appears  on  the  planet  as  a  dark,  sharply  outlined  band. 
They  move  around  the  planet  at  varying  speeds— the  ring  nearest 
Saturn  is  the  fastest;  the  outer  ring,  the  slowest. 

Saturn  is  the  last  of  the  planets  that  we  can  see  with  the  naked 
eye.  It  is  another  of  the  "giants,"  second  only  to  Jupiter  in  size. 
As  in  the  case  of  Jupiter,  clouds  of  poisonous  gases  form  bands 
across  the  surface  of  Saturn,  but  they  are  much  fainter  than 
Jupiter's  bands.  Despite  its  great  size,  Saturn  does  not  appear 
nearly  so  brilliant  to  the  naked  eye  as  Jupiter  does.  Saturn  is 
millions  of  miles  farther  away  from  us. 

Uranus  and  Neptune— Distant  Planets 

These  planets  are  so  far  away  from  us  that  only  a  person  with 
exceptional  eyesight  can  possibly  see  Uranus  without  the  aid  of  a 
telescope,  while  Neptune  is  always  invisible  to  the  naked  eye. 
Both  of  these  planets  resemble  Jupiter  and  Saturn  in  having 
clouds  of  ammonia  and  methane  in  their  atmosphere.  And  though 
they  are  smaller  than  Jupiter  and  Saturn,  they  are  nevertheless 
classed  as  giants. 

Uranus  is  about  thirty-two  thousand  miles  in  diameter  and  takes 
eighty-four  of  our  years  to  complete  its  revolution  around  the  sun. 
Even  through  a  telescope  there  is  little  to  look  for  on  Uranus.  It 
appears  as  a  small  greenish  disk  with  vague  belts  across  the  surface. 
It  has  four  satellites. 

Neptune,  as  we  have  seen,  is  completely  invisible  except  with 
the  aid  of  a  fairly  powerful  telescope.  Still,  it  has  a  diameter  of 
about  thirty-three  thousand  miles,  and  its  period  of  revolving 


^g8  ]  Our  Earth  and  Its  Fellow  Planets 

about  the  sun  requires  almost  165  of  our  years.  It  has  one  satellite 
and,  like  Uranus,  is  greenish  in  color. 

How  Uranus  and  Neptune  Were  Discovered 

It  is  interesting  to  realize  that  Uranus  was  discovered  purely 
by  accident  in  1781— thousands  of  years  after  people  first  began  to 
watch  the  heavens  and  firmly  concluded  there  were  no  planets 
beyond  Saturn.  The  discoverer  of  Uranus  was  Sir  William 
Herschel,  a  great  British  astonomer,  whose  name  is  sometimes 
given  to  it. 

Neptune  was  found  independently  in  1846  by  two  different 
astronomers— each  unknown  to  the  other  I  They  noticed  that 
Uranus  did  not  always  follow  its  exj>ected  course,  and  they  specu- 
lated that  this  might  be  due  to  the  influence  of  another,  hitherto 
unknown,  planet.  After  several  years  of  study  and  calculations, 
each  man  in  his  own  way  located  the  "new"  planet,  which  was 
named  Neptune.  Science  had  rung  up  another  curtain,  revealed 
another  secret  of  the  mysterious  universe  that  is  our  home. 

Pluto— Most  Distant  of  Them  All 

The  most  recently  discovered  planet  (it  was  first  seen  in  1930) , 
Pluto  is  completely  beyond  the  range  of  a  small  telescope.  Small 
wonder— Pluto  is  almost  four  billion  miles  away  from  us!  It  is  the 
planet  most  distant  from  the  sun,  and  requires  nearly  250  of  our 
years  to  complete  one  trip  around  it. 

Pluto  does  not  compare  in  size  to  the  giant  planets,  and  is  prob- 
ably somewhat  smaller  than  the  earth.  One  interesting  theory 
about  the  origin  of  Pluto  is  that  it  may  have  started  as  an  escaped 
satellite  of  its  nearest  planetary  neighbor,  Neptune.  Scientists 
believe  that  Pluto  has  little  or  no  atmosphere,  as  it  reflects  light 
very  poorly.  Pluto  is  yellowish  in  color. 

Though  this  planet  was  named  for  the  god  of  the  underworld, 
the  first  two  letters  PL  are  used  for  its  symbol,  and  these  are  the 
initials  of  a  great  astronomer,  Percival  Lowell.  It  was  Dr.  Lowell 
who  calculated  how  a  planet  in  the  realm  of  Pluto  must  move. 


Our  Earth  and  Its  Fellow  Planets  [  399 

However,  Pluto  was  not  discovered  until  twenty-five  years  after 
his  death  I 

The  Mysterious  Minor  Planets 

With  a  telescope  you  may  make  the  acquaintance  of  another 
group  of  heavenly  bodies  that  are  not  stars— for  they  are  within 
our  solar  system— and  yet  lack  the  full  status  of  planets.  These  are 
the  asteroids  (from  the  Greek  word  aster,  meaning  "star") .  They 
are  found  in  the  great  gulf  of  space  between  the  orbits  of  Mars 
and  Jupiter. 

Even  through  the  telescope  the  asteroids  show  up  only  as  points 
of  light  (like  the  stars),  though  they  have  the  solid  mass  of  planets. 
This  is  explained  by  the  far  smaller  size  of  the  asteroids  as  com- 
pared to  the  full  planets;  the  largest  asteroid  is  less  than  five 
hundred  miles  across  and  the  smallest,  only  five  or  ten  miles. 

Solving  the  Puzzle  of  the  Minor  Planets 
The  answer  to  the  puzzle  of  why  several  thousand  of  these 
minor  planets  (or  asteroids)  exist  in  an  area  where  one  single 
planet  might  be  expected,  may  lie  in  the  theory  that  once  a  single 
planet  did  move  along  this  path.  This  unknown  planet  may  have 
broken  into  the  thousands  of  fragments  that  now  continue  to  move 
in  the  same  path.  Meteorites  that  strike  our  earth  are  also  believed 
to  be  the  remains  of  this  vanished  planet. 

The  Moon— Our  Neighbor  in  Space 

To  young  children,  the  moon  is  probably  the  most  interesting 
object  in  the  sky.  It  is  by  far  the  brightest  of  the  night  sky;  and 
though  the  sun  is  overwhelmingly  brighter,  it  does  not  have  the 
moon's  rather  mysterious  appeal.  The  moon's  gradual  disappear- 
ance and  equally  gradual  return  to  view  each  month  may  seem  very 
odd,  to  say  the  least,  until  a  child  understands  the  cause. 

A  child  may  take  in  all  seriousness  talk  about  "the  man  in  the 
moon,"  and  by  the  time  he  realizes  that  this  is  merely  an  imagina- 
tive phrase,  he  may  have  begun  to  wonder  about  such  terms  as 
the  "craters"  and  the  dark  plains   (often  called  seas  or  "maria") 


^oo  ]  Our  Earth  and  Its  Fellow  Planets 

of  the  moon— terms  concerned  with  facts  rather  than  fancy.  As  he 
grows  older  he  may  have  the  exciting  dream  of  going  to  the  moon 
by  rocketship;  being  the  nearest  of  the  heavenly  bodies,  the  moon 
is  the  first  that  scientists  hope  to  reach. 

What  Makes  "The  Man  in  the  Moon" 

A  powerful  telescope  gives  spectacular  results  when  it  is 
trained  on  the  moon,  but  we  can  still  learn  many  things  about  its 
surface  by  observing  it  with  field  glasses  or  a  small  telescope.  Con- 
spicuous even  to  an  unaided  eye  are  the  large  dark  spots  we  like 
to  associate  with  a  man's  face,  a  rabbit,  and  other  fancies. 

Through  a  telescope  we  can  see  these  spots  better.  They  are 
craters— great  circular  depressions.  Some  are  fifty  miles  or  more  in 
diameter,  with  walls  thousands  of  feet  high;  others  are  small  pits 
without  walls.  Many  astronomers  believe  the  craters  were  formed 
by  volcanoes,  but  others  suggest  that  large  meteors  falling  upon 
the  moon  created  them. 

Phases  of  the  Moon 

The  dark  spots  give  further  emphasis  to  the  fact  that  the 
moon  (like  the  planets)  has  no  light  of  its  own;  the  brilliance  of 
the  moon  is  all  reflected  light.  And  because  it  borrows  its  light 
from  the  sun,  the  moon  has  * 'phases"  that  range  from  crescent  to 
"first  quarter"  to  "full"  to  "last  quarter"  to  crescent  again.  With 
light  of  its  own  the  moon  would  not  be  so  changeable. 

What  Produces  the  Phases:  To  understand  the  phases,  we  must 
keep  in  mind  several  facts:  The  sun  is  ninety-three  million  miles 
from  our  earth.  The  moon  is  a  mere  240,000  miles  from  us.  The 
moon  revolves  around  the  earth,  as  the  earth  revolves  around  the 
sun.  But  whereas  the  earth  takes  a  year  to  make  its  revolution  the 
moon  requires  only  a  month  for  its  journey.  (The  word  "month" 
is  derived  from  "moon.") 

We  cannot  see  the  moon  at  all  when  it  comes  between  us  and 
the  sun,  for  the  side  of  the  moon  that  faces  the  earth  then  reflects 
no  light.  When  we  are  able  to  see  a  thin  sliver  of  light  on  its  edge, 
which  now  faces  the  sun,  we  call  it  the  crescent  or  "new"  moon. 


Our  Earth  and  Its  Fellow  Planets  [  401 

About  a  week  later,  when  the  moon  has  moved  a  quarter  of  the 
way  around  its  orbit,  we  can  see  half  of  its  bright  side  (first 
quarter) . 

In  another  week  the  moon  is  opposite  the  sun,  and  appears  full, 
for  we  can  see  all  of  its  bright  side.  (During  this  period  the  moon 
rises  about  sunset  and  remains  in  the  sky  all  night.)  Still  another 
week  brings  the  moon  three-quarters  of  the  distance  of  its  orbit 
and  we  again  see  half  of  the  bright  side  (third  quarter).  The  moon 
goes  through  all  these  phases  each  month. 

It  happens  that  the  moon  rotates  on  its  axis  in  just  the  same 
time  that  it  revolves  about  the  earth,  with  the  result  that  the  same 
face  is  always  turned  towards  usi  No  one  has  ever  seen  the  other 
side— the  intriguing  "hidden  side"  of  the  moon. 

What  We  Will  Find  on  the  Moon 

If  the  time  comes  when  we  can  shoot  in  a  rocketship  to  the 
moon,  we  shall  have  to  take  oxygen  tanks  along;  there  is  no  air  on 
this  planet-like  heavenly  body.  The  territory  to  be  explored  will 
be  far  less  than  on  the  earth,  for  the  moon's  diameter  is  only  2,160 
miles— in  contrast  to  the  earth's  7,918-mile  diameter. 

We  probably  would  not  regret  the  small  size,  for  there  is  a 
terrible  sameness  about  the  moon's  landscape.  Rocks,  rocky  plains, 
and  rocky  mountains  are  on  all  sides  of  us.  No  trees,  flowers,  or 
even  grass  break  the  monotony  and  no  birds  or  other  animals  give 
life  to  the  scene.  If  we  clap  our  hands  to  break  the  eerie  quiet,  we 
still  hear  nothing!— without  air  there  can  be  no  sound  waves. 

Knowing  as  we  do  that  the  force  of  gravitation  on  the  moon  is 
low  compared  with  that  of  our  earth,  we  check  our  weight. 
Whereas  on  earth  we  weighed  120  pounds,  we  are  now  just  twenty 
pounds— only  a  sixth  of  our  accustomed  weight!  In  this  feather- 
weight condition  we  find  that  we  can  get  around  with  great  strides. 
So  we  climb  easily  over  the  moutains,  dome-shaped  hills,  and 
mountain-ringed  plains.  We  have  no  worries  about  weather  for 
the  moon,  being  without  moisture,  has  no  clouds,  rain,  snow,  or 
wind. 


402  ]  Our  Earth  and  Its  Fellow  Planets 

These  things  we  know  about  the  moon,  but  many  others  we  do 
not.  Its  first  explorers  will  doubtless  find  out  much  we  on  earth 
cannot  possibly  discover  even  with  our  wonderful  scientific  instru- 
ments. 

How  THE  Moon  Was  Formed 

Satellites  are  generally  very  tiny  in  relation  to  the  size  of 
the  parent  bodies  around  which  they  revolve.  The  other  planets, 
for  example,  have  several  hundred  thousand  times  the  mass  of 
their  satellites.  But  the  moon  is  an  exception:  Our  earth  has  only 
eighty-one  times  the  mass  of  the  moon.  One  explanation  of  this  is 
found  in  the  theory  that  our  moon  separated  from  the  earth  at  a 
comparatively  late  stage  of  the  earth's  development,  when  it  had 
cooled  to  a  liquid  form. 

At  this  point,  so  runs  the  theory,  gravitational  forces  from  the 
sun  acted  to  form  a  bulge  on  our  earth.  In  time  this  bulge  sepa- 
rated as  a  giant  teardrop  and  moved  out  into  space  to  occupy  its 
present  orbit  encircling  the  earth.  Held  in  its  orbit  by  the  con- 
tinual pulling  force  of  the  sun  as  well  as  by  that  of  the  earth,  the 
moon  exerts  its  own  pull  on  the  earth.  (This  pull  of  the  moon  is 
reflected  in  our  tides.  The  highest  tides  each  month  come  with  the 
full  moon  and  the  new  moon.) 

To  support  this  interesting  theory  the  astronomers  have  brought 
geology  to  their  aid  by  suggesting  that  the  moon's  tearing  away 
from  the  earth  left  a  visible  scar  on  our  planet.  The  fact  that  the 
entire  Pacific  Ocean  basin  has  a  different  surface  rock  structure- 
basalt  rather  than  the  granite  common  to  other  areas— has  led  some 
scientists  to  accept  this  area  as  the  region  where  the  moon  carried 
away  a  large  portion  of  our  forming  earth. 

WH'i'  We  Have  Eclipses  of  the  Moon 

Every  once  in  a  while  the  moon  stages  a  show  that  fascinates 
children  as  well  as  adults.  This  happens  at  the  times  when  the 
moon  goes  into  the  shadow  of  the  earth,  and  we  say  there  has  been 
an  eclipse  of  the  moon. 


Our  Earth  and  Its  Fellow  Planets 


SUN'S  RAYS 


[403 


THE  MOON   IS  ECLIPSED  WHEN   COVERED   BY  THE  EARTH'S  SHADOW 

An  eclipse  of  the  moon  does  not  occur  each  time  the  moon  mokes  its  circle  around 
the  earth;  usually  the  sun  passes  above  or  below  the  earth's  tapering  shadow, 
which  is  nearly  a  million  miles  long!  But  when  sun,  earth,  and  moon  ore  in  line, 
the  earth  blots  out  the  sun's  rays.  However,  some  of  these  rays  are  bent  in  passing 
through  the  earth's  atmosphere— enough  to  make  the  moon  faintly  visible,  with 
a  coppery  tint.  Astronomers  predict  these  eclipses  with  extraordinary  precision. 


In  its  journey  around  the  earth,  the  moon  usually  passes  once  a 
month  either  below  or  above  the  shadow  cast  from  the  darkened 
side  of  the  earth.  But  sometimes  the  moon  passes  through  this 
earth  shadow  and  then  becomes  nearly  invisible— eclipsed.  A  whole 
year  may  go  by  without  a  lunar  eclipse;  in  another  year  there  may 
be  as  many  as  three  eclipses. 

On  some  of  these  occasions  the  moon  passes  through  the  edge  of 
the  shadow  and  only  part  of  it  is  darkened;  at  other  times  it  is 
completely  in  the  shadow.  But  even  during  a  total  eclipse  the 
moon  does  not  entirely  disappear  from  view— it  only  dims  and 
changes  color.  The  point  is  that  it  does  not  completely  lose  all 
sunlight.  Some  of  that  light  is  refracted  (bent)  by  the  earth's 
atmosphere;  and  because  red,  orange,  and  yellow  pass  most  easily 
through  the  atmosphere,  the  moon  appears  a  deep  copper  color 
when  it  is  eclipsed. 

Astronomers  can  predict  eclipses.  Newspapers  and  almanacs  tell 
when  they  will  occur,  and  from  what  places  they  may  be  seen.

Seeing  the  Skies  "Indoors" 

If  it  is  at  all  possible,  you  will  not  want  to  miss  the  experience 
of  visiting  one  of  the  great  planetariums.  It  is  the  best  way  for  a 
child  to  get  a  good  basic  understanding  of  our  solar  system  and 
the  stars  that  surround  it.  There  are  six  planetariums  in  the 
United  States— in  Los  Angeles,  Chicago,  Pittsburgh,  Philadelphia, 
New  York,  and  Chapel  Hill,  North  Carolina. 

When  you  enter  a  planetarium,  your  child  will  be  curious  about 
the  weird-looking  instrument  that  stands  on  a  platform  in  the 
center  of  the  domed  room.  This  is  the  projector— rather  like  a 
motion-picture  projector  but  far  more  complicated.  The  "show" 
begins,  the  room  is  plunged  into  darkness,  and  the  projector 
throws  on  the  rounded  ceiling  images  of  the  stars  and  planets.  As 
these  bodies  move  about  in  "the  heavens,"  the  speaker  explains 
their  movements;  inside  an  hour  you  may  watch  them  go  through 
motions  that  would  normally  take  days,  months,  or  years. 

The  sky  may  be  pictured  as  it  was  at  the  birth  of  Christ  or  when 
Columbus  arrived  in  America;  or  it  may  be  shown  as  it  should 
appear  hundreds  of  years  from  now.  As  he  looks  on,  the  child 
can  feel  a  thrilling  closeness  to  the  distant  past  when  intrepid 
explorers  guided  their  ships  by  the  stars  and  peaceful  shepherds 
used  the  stars  to  tell  time.  He  can  feel,  too,  a  comforting  confidence 
in  the  future  as  it  becomes  evident  that  though  stars,  moon,  and 
planets  disappear  from  view,  each  in  its  own  proper  time  will  be 
back  again. 


CHAPTER 


O  Recognizing 
the  Stars 


HE 

]lth( 


HE  SUN  is  of  course  the  most  familiar  of  all 
the  stars— and  yet  not  everyone  realizes  that 
it  is  a  star!  It  appears  large  and  red,  instead  of  small  and  cool  like 
other  stars,  because  it  is  closer  to  us.  The  sun  is  more  important 
to  us  than  any  other  body  in  the  heavens.  Without  it,  the  scientists 
tell  us,  life  could  not  have  begun  on  our  planet;  and  if  the  sun 
were  to  vanish,  life  would  be  hard  put  to  survive. 

We  can  see  all  about  us  the  results  of  the  energy  that  the  sun 
gives  to  the  earth.  We  owe  almost  all  our  heat  and  light  as  well  as 
energy,  to  the  influence  of  this  great  ball  of  fiery  gas.  Plants  cannot 
grow  without  its  beneficent  rays,  and  the  animals  in  turn  draw 
life-sustaining  energy  from  the  plants.  It  is  not  surprising  that 
ancient  peoples  worshiped  the  sun  as  their  supreme  god,  and 
that  to  us  the  word  "sunshine"  means  "happiness." 

The  sun  is  blazing  hot— hot  beyond  belief.  It  helps  us  to  get 
some  idea  of  the  sun's  temperature  when  we  consider  how  hot  it 
is  in  midsummer  despite  the  fact  that  the  nearest  we  ever  come  to 
the  sun  is  well  over  ninety  million  miles!  The  surface  temperature 
of  the  sun  is  about  5,800°  centigrade.  Inside  its  burning  body  the 
temperature  may  be  millions  of  degrees  higher. 

The  sun  gives  the  illusion  of  varying  in  brightness  and  also  in 
size.  Late  in  the  day,  as  the  sun  sinks  toward  the  western  horizon,

its  glare  is  reduced  so  that  you  can  watch  it  briefly  without  ill 
effect.  At  this  time  it  appears  to  grow  larger;  but  if  you  roll  a 
sheet  of  paper  into  a  tube  and  look  through  it,  the  sun  will  resume 
its  usual  size.  The  "change"  of  size  is  one  of  nature's  interesting 
illusions. 

Spots  on  the  Sun 

If  you  look  at  the  sun  through  a  telescope  equipped  with  a 
specially  darkened  filter,  you  may  observe  some  dark  spots  on  its 
bright  yellow  surface,  possibly  grouped  in  pairs  or  clusters.  You 
would  see  them  apparently  moving  across  the  disk  a  short  distance 
each  day  as  the  sun  turns  on  its  axis. 

These  "sunspots"  would  appear  very  tiny  in  your  telescope,  but 
in  reality  each  one  of  them  might  be  as  large  as  our  earth— or 
larger.  The  earth  is  a  mere  speck  compared  to  the  sun,  which 
requires  twenty-five  of  our  days  to  complete  a  turn  on  its  axis  and 
has  a  mass  332,000  times  greater  than  that  of  the  earth! 

What  Sunspots  Are:  A  sunspot  is  believed  to  begin  in  a  column 
of  gas  that  rises  from  far  below  the  surface  of  the  sun.  This  column 
is  pushed  upward  to  the  surface  by  energy  supplied  by  its  own 
heat.  This  expended  energy  results  in  a  shallow  layer  of  gas  at  the 
top  of  the  column.  The  top  layer  is  cooler  than  its  surroundings 
and  therefore  appears  darker. 

The  number  and  frequency  of  sunspots  vary,  but  they  have  a 
way  of  increasing  and  gathering  in  larger  groups  for  several  years, 
then  becoming  less  and  less  frequent  until  the  sun  is  quite  clear  of 
them.  On  the  average,  about  eleven  years  elapse  between  one 
period  of  great  spottedness  to  the  next. 

Tracing  the  Influence  of  Sunspots:  There  has  naturally  been  a 
great  deal  of  speculation  about  the  possible  effects  of  sunspots  on 
our  earth.  Occasionally  scientists  have  thought  they  could  trace  a 
connection  between  "storms"  on  the  sun  and  stormy  weather  on 
the  earth.  However,  observers  in  the  United  States  Weather 
Bureau  have  not  yet  succeeded  in  tracing  any  direct  influence  of 
sunspots  on  our  storms. 


Recognizing  the  Stars  [  407 

However,  these  observers  feel  more  certain  about  a  connection 
between  sunspots  and  the  northern  lights  (aurora  borealis)  often 
seen  from  Alaska,  Canada,  and  northern  Europe,  and  also  between 
sunspots  and  the  so-called  magnetic  storms  that  sometimes  inter- 
fere with  radio  reception.  These  storms  and  the  northern  lights 
have  never  been  traced  to  any  particular  sunspots,  but  they  have 
been  most  numerous  during  years  when  the  sun  was  heavily 
"spotted." 

"Granules"  Hundreds  of  Miles  Across:  You  would  need  to  use 
a  large  telescope  to  discover  that  the  sun's  surface  is  not  smooth, 
but  apparently  made  up  of  countless  grains  (usually  called  "gran- 
ules") that  are  believed  to  be  rising  streams  of  hot  gases.  Though 
they  look  small  to  us,  they  have  been  estimated  as  anywhere  from 
about  four  hundred  to  a  thousand  miles  across!  The  sun  probably 
contains  the  same  chemical  elements  as  its  daughter,  the  earth, 
but  these  remain  in  the  form  of  gas  because  of  the  intense  heat. 

Eclipses  of  the  Sun 

When  the  moon  is  in  a  direct  line  between  the  earth  and 
the  sun,  we  have  a  total  eclipse  of  the  sun.  This  kind  of  eclipse 
does  not  happen  often;  hundreds  of  years  may  pass  between  total 
eclipses  in  any  one  part  of  the  earth.  Sunlight  is  so  taken  for 
granted  that  even  the  prospect  of  an  eclipse  is  of  wide  interest 
and  appeals  not  only  to  scientists,  but  to  all  people,  young  and  old. 
We  can  see  an  eclipse  of  the  sun  from  only  a  small  area— for  a 
total  eclipse  the  area  is  about  sixty  miles  wide— while  an  eclipse

THE  MOON,  BETWEEN   SUN   AND  EARTH,  MAKES  A  SOLAR  ECLIPSE 

When  the  moon  passes  between  the  earth  and  sun,  the  sun  is  eclipsed.  However, 
we  see  a  tofal  eclipse  of  the  sun  from  no  more  than  a  small  portion  of  the  earth — 
that  area  on  which  the  tapering  shadow  of  the  moon  falls.  From  a  much  wider 
area   the    sun    is   only   partly   hidden    and    here   observers   see    a    partial    eclipse. 


4o8  ]  Recognizing  the  Stars 

of  the  moon  can  be  seen  anywhere  on  the  side  of  the  earth  where 
it  is  night.  This  is  explained  by  the  fact  that  the  earth's  shadow 
is  large  enough  to  cover  the  whole  moon  (during  a  lunar  eclipse) , 
whereas  the  moon's  shadow  is  small  and  covers  only  a  small  part 
of  the  earth. 

How  the  Sun  is  "Blotted  Out'*:  "How  can  the  moon  ever  'blot  out' 
the  entire  sun,  if  the  sun  is  so  much  bigger?"  a  child  may  wonder. 
If  he  holds  a  dime  at  arm's  length  he  will  find  that  the  small 
coin  seems  to  more  than  cover  the  moon.  This  same  principle 
operates  when  we  see  the  nearby  moon  between  us  and  the  distant 
sun.  While  the  sun's  diameter  is  four  hundred  times  larger  than 
that  of  the  moon,  the  sun  is  also  four  hundred  times  farther  away, 
and  the  two  disks  seem  of  equal  size. 

Atomic  Energy  and  the  Sun 

Children  take  a  lively  interest  in  the  information  that  the 
sun's  energy  is  atomic,  and  that  this  giant  heavenly  body  was 
producing  atomic  energy  before  the  earth  began.  Long  ago  people 
believed  that  the  sun  was  merely  a  great  burning  mass;  but  if  this 
had  been  true,  it  would  have  burned  itself  out  in  less  than  two 
thousand  years.  When  scientists  realized  that  this  idea  must  be 
wrong,  they  were  puzzled  about  the  secret  of  the  sun's  energy— 
until  they  discovered,  quite  recently,  that  an  atom  could  be  split, 
releasing  an  enormous  amount  of  energy.  This  solved  the  puzzle 
of  the  sun's  energy  1 

The  term  "atom"  (taken  from  a  Greek  word  meaning  "indiv- 
isible") had  been  chosen  for  what  was  believed  to  be  the  tiniest 
possible  unit  of  matter.  We  now  know  that  these  units  are  made 
of  still  smaller  particles  that  are  in  motion— and  are  constantly 
changing  into  new  forms.  The  change  may  be  sudden  and  violent, 
as  in  an  atomic  bomb,  or  slow  and  gradual. 

In  the  case  of  the  sun,  hydrogen  atoms  are  changing  into  helium 
atoms.  To  be  specific,  four  hydrogen  atoms  are  changed  into  one 
helium  atom,  and  one  per  cent  of  their  weight  is  converted  into 
atomic  energy.  This  means  that  the  sun,  with  its  countless  active 
atoms,  is  constantly  growing  smaller,  or  losing  weight;  but  it  is  so 


Recognizing  the  Stars  [  409 

enormous  that  it  can  continue  to  shrink  at  its  present  rate  for 
billions  of  years  without  affecting  the  earth! 

Safety  Measures  for  Sun  Observation 

If  you  are  interested  in  sun-watching,  you  must  always 
keep  in  mind  how  dangerous  it  is  to  look  directly  at  it,  even  for 
a  moment.  To  impress  this  on  your  child,  you  can  hold  a  reading 
glass  in  the  sunlight  so  that  it  will  focus  the  rays  on  a  piece  of 
paper.  Before  long  a  hole  will  burn  in  the  paper— a  dramatic  il- 
lustration of  the  power  of  the  sun. 

As  for  using  an  instrument,  anyone  looking  at  the  sun  through 
a  telescope  not  equipped  with  a  darkened  lens,  would  be  blinded. 
Observing  the  sun  is  safe  only  with  a  proper  telescope,  or  heavily 
smoked  glass,  or  several  thicknesses  of  photographic  film. 

For  interesting  and  easily  managed  sun  observations,  you  can 
note  and  record  the  time  of  sunset  and  sunrise  over  a  period  of 
several  months  and  also  the  points  on  the  horizon  at  which  the 
sun  rises  and  sets  during  the  same  period.  In  this  way  you  have 
first-hand  information  about  its  gradual  shift  northward  (as  seen 
from  northern  latitudes)  from  December  2 1  to  June  2 1 ;  you  can 
then  chart  its  reverse  trip  southward  from  June  2 1  to  December  2 1 . 

Stars  Beyond  the  Sun 

The  sun  is  four  hundred  times  farther  away  from  us  than  is  the 
moon.  Yet  the  sun,  in  comparison  to  the  other  stars,  is  a  nearby 
star!— that  is  why  it  appears  large  and  red.  This  fact  will  give  a 
youngster  some  notion  of  the  incredibly  vast  distances  between  us 
and  the  other  stars. 

The  average  size  of  a  star  is  about  equal  to  the  size  of  the  sun. 
Many  stars  that  we  can  see  with  unaided  eye  are  much  larger  than 
the  sun;  on  the  other  hand,  countless  stars  that  can  be  seen  only 
through  telescopes  are  smaller  than  the  average  size. 

Hundreds  of  Thousands  of  Light-Years  Away 

The  real  stars  (as  distinguished  from  the  wandering  plan- 
ets) we  know  as  "fixed"  stars.  Scientists  have  reckoned  that  light. 


^lo  ]  Recognizing  the  Stars 

moving  at  a  rate  of  186,000  miles  a  second,  takes  four  years  to 
travel  from  the  nearest  fixed  star— other  than  the  sun— to  our 
earth.  This  impressive  figure  is  a  useful  one  to  remember,  for  it 
involves  the  "light-year"  previously  mentioned,  which  is  used  as  a 
unit  of  measurement  in  astronomy.  (A  light-year  is  the  distance 
light  travels  in  one  year.) 

Looking  at  the  night  sky,  we  have  the  illusion  that  all  the 
stars  are  the  same  distance  from  us,  with  some  larger  than  others. 
However,  their  apparent  size  is  partly  dependent  on  their  location. 
Some  of  these  stars  are  hundreds  of  thousands  of  light-years  awayl 

How  Stars  Seem  to  Move 

When  we  talk  about  "fixed"  stars,  it  is  a  good  idea  to 
remind  a  child  that  the  earth  rotates  on  its  axis.  It  is  this  real 
motion  of  the  earth  that  explains  the  apparent  motion  of  the  stars. 
The  youngster  should  also  bear  in  mind  that  the  axis  of  the  earth, 
if  it  could  be  extended,  would  pierce  the  northern  sky  a  short 
distance  from  the  North  Star,  or  polestar,  known  also  as  Polaris. 

Polaris,  the  North  Star:  Polaris  is  the  only  star  in  the  sky  that  never 
seems  to  move.  While  it  remains  nearly  stationary,  the  other 
constellations  seem  to  move  around  it.  If  we  look  for  Polaris  from 
a  position  just  north  of  the  equator,  we  will  locate  it  barely  above 
the  horizon.  As  we  travel  northward,  it  seems  to  be  higher  and 
higher  in  the  sky.  If  we  went  as  far  as  the  North  Pole,  we  would 
find  Polaris  directly  overhead. 

The  North  Star  has  guided  sailors  for  centuries  in  determining 
their  position  at  sea.  In  the  southern  sky,  where  the  earth's  axis 
would  touch  if  extended,  there  is  no  star  bright  enough  to  serve 
as  a  comparable  guide  to  seamen. 

The  heavens  look  different  depending  on  what  part  of  the  earth 
you  view  them  from.  Thus,  from  the  United  States  and  Canada 
we  cannot  see  the  stars  that  circle  the  South  Pole;  and  the  people 
who  live  in  Australia,  southern  Africa,  or  South  America,  cannot 
see  the  stars  around  the  North  Pole.  It  is  only  from  locations  along 
the  equator  that  all  the  stars  can  be  seen.

Constellations  in  the  Night  Sky 

With  their  vivid  imagination  and  quick  flair  for  fanciful  pat- 
terns, children  seize  eagerly  on  the  constellations,  those  pictorial 
star-groups  that  hark  back  to  the  childhood  of  civilization.  At  the 
time  of  Christ,  more  than  forty  of  these  sky  pictures  had  become 
generally  accepted;  over  the  succeeding  centuries  more  were 
worked  out,  and  today  astronomers  officially  recognize  eighty-eight 
constellations.  (The  word  "constellation"  is  taken  from  two  Latin 
words  meaning  "stars  together.") 

The  stars  in  a  constellation  may  differ  in  brightness,  distance 
from  us,  and  in  size;  their  only  relationship  is  created  as  our  eyes 
move  from  one  to  another  and  we  draw  our  imaginary  picture 
bringing  a  group  into  focus.  Some  constellations,  such  as  Sagitta 
(the  Arrow) ,  have  few  bright  stars  and  the  area  they  cover  is 
small.  Ursa  Major  (the  Great  Bear),  Hydra  (the  Water  Monster) 
and  Hercules  are  among  the  very  large  constellations. 

The  constellations  near  the  North  Star  go  around  the  pole  (in 
terms  of  apparent  motion)  every  twenty-four  hours  and  are  visible 
throughout  the  year.  How  many  constellations  you  can  see  con- 
stantly, depends  on  your  location  between  the  pole  and  the 
equator.  From  the  greater  part  of  the  United  States  we  can  ob- 
serve six  that  never  set:  the  Great  Bear,  the  Little  Bear,  the  Dragon, 
Cepheus  (se  fus) ,  Cassiopeia  (kas  io-pe  yah) ,  and  Camelopardalis 
(kah-mel  o-par-dah-lis).  From  Canada  and  the  northernmost 
United  States  about  ten  others  can  be  seen,  wholly  or  in  part, 
through  all  seasons. 

The  Great  Bear  and  the  Big  Dipper 

The  Great  Bear  is  usually  the  first  constellation  with  which 
children  become  familiar.  "Great  Bear"  is  the  translation  of  the 
Latin  name  Ursa  Major;  in  the  United  States  a  part  of  the  constel- 
lation is  famous  as  the  Big  Dipper.  This  is  the  most  easily  recog- 
nized of  constellations,  and  of  further  importance  as  the  guidepost 
to  the  North  Star. 

If  you  imagine  a  line  joining  the  two  stars  that  form  the  side 
of  the  Dipper's  bowl  farthest  from  the  handle,  and  then  extend 


412] 


Recognizing  the  Stars 


USE  THIS  STAR  AUP  TO  FIND  THE  CONSTELLATIONS 
IN  THE  NORTHERN  SKY,  AT  ANY  TIME  OF  YEAR 

Inside  the  circle,  you  see  the  star  groups  around  Polaris.  You  can  always  find  them 
on  any  clear  night  in  the  year,  for  they  never  go  below  the  horizon.  If  you'd  like 
to  locate  some  of  these  northern  star  groups  tonight,  here  is  what  you  do: 

Find  the  name  of  the  present  month  on  the  circle,  and  turn  the  book  so  that  this 
name  comes  at  the  top.  Then  look  on  the  map  for  the  Big  Dipper  (Ursa  Major). 

If  the  month  on  top  of  the  circle  is  February,  you  will  find  the  bowl  of  the 
Dipper  at  the  right  of  the  polestar.  If  May  is  on  top,  the  bowl  will  be  high  above 
the  pole.  If  it  is  August,  the  bowl  will  be  at  the  left;  and  in  November  the  Dipper 
will  be  directly  below  the  polestar.  The  sky  turns  a  quarter  way  round  every  three 
months;  one-twelfth  of  the  circle  each  month. 

This  map  shows  the  positions  of  the  Dipper  (and  the  other  star  groups)  at  about 
eight  o'clock  in  the  evening.  If  you  look  for  them  two  hours  later,  you  will  find  them 
advanced  (in  a  counterclockwise  direction)  another  twelfth  of  the  way  round  the 
circle.  Each  twelfth  is  two  hours;  each  twenty-fourth  is  one  hour. 


Recognizing  the  Stars  [413 

this  line  through  the  top  of  the  Dipper  for  five  times  that  length, 
it  will  end  at  the  North  Star.  For  this  reason,  the  two  stars  at  the 
Dipper's  bowl  are  often  called  the  "pointers." 

All  four  stars  that  form  the  bowl  of  the  Dipper  and  the  three 
that  make  the  handle  are  of  about  the  same  degree  of  brightness, 
making  the  form  of  a  dipper  especially  clear.  If  you  keep  tiack 
of  the  Dipper  for  three  or  four  hours,  you  will  see  that  it  is  moving 
like  a  giant  clock  hand— "counterclockwise,"  however— around 
Polaris.  Unless  you  look  carefully  you  may  not  see  the  stars  con- 
tained within  the  bowl  of  the  Dipper;  but  with  close  observation 
on  a  clear  night,  you  should  be  able  to  distinguish  ten  or  twelve 
faint  stars. 

The  Little  Bear  and  the  Little  Dipper 

You  will  not  find  the  Little  Bear  so  easily  as  the  Big  Bear, 
for  many  of  its  stars  are  dim  and  may  be  overlooked  in  moonlight 
or  haze.  Seven  of  its  stars  form  the  Little  Dipper,  with  the  bright 
North  Star  forming  the  free  end  of  the  handle.  The  two  stars  that 
correspond  to  the  pointers  in  the  Big  Dipper  (farthest  from  the 
handle)  are  also  bright.  These  two  stars  are  known  as  "the 
guardians  of  the  pole"  because  they  circle  closer  to  it  and  to  Polaris 
than  do  any  other  bright  stars. 

The  Winding  Dragon 

Winding  about  the  Dippers  is  Draco,  the  Dragon.  To  locate 
it,  you  must  look  for  a  stream  of  stars  that  starts  near  the  pointers 
in  the  Big  Dipper.  From  there  the  dragon  makes  a  semicircle 
around  the  guardians  of  the  pole,  then  turns  sharply  back  for 
some  distance;  the  dragon's  head  lies  between  a  very  bright  star, 
Vega,  and  the  guardians. 

Cassiopeia  and  Cepheus 

Cassiopeia  is  nearly  directly  opposite  the  Big  Dipper,  on 
the  other  side  of  the  pole.  Hence,  when  one  of  these  constellations 
is  not  in  a  good  position  for  observation,  the  other  is.  Five  of  the 
brighter  stars  of  Cassiopeia  form  a  giant  irregular  W  (or  M,  de- 


414  ]  Recognizing  the  Stars 

pending  on  your  location).  One  less  bright  star  is  sometimes  in- 
cluded in  the  group,  and  when  it  is,  the  constellation  may  be 
fancied  as  a  broken-backed  chair,  sometimes  called  Cassiopeia's 
chair. 

In  Greek  mythology  Cassiopeia  was  a  queen,  and  Cepheus  was 
her  king.  In  the  heavens,  Cepheus  is  located  next  to  Cassiopeia. 
Cepheus  contains  no  very  bright  stars,  but  you  can  locate  it  by 
looking  along  an  imaginary  line  from  the  pointers  of  the  Big 
Dipper  through  the  North  Star,  and  then  continuing  on  for  about 
the  same  distance  again.  Some  of  its  stars  form  a  crude  square  and 
others  make  a  triangle  resting  on  the  square.  The  Milky  Way 
runs  through  Cepheus. 

Camelopardaus 

When  you  go  sky-exploring  in  quest  of  Camelopardalis 
you  will  want  to  choose  a  clear  moonless  night;  this  constellation 
is  made  up  of  nothing  but  faint  stars.  Though  its  name  suggests 
a  camel,  the  constellation  is  actually  supposed  to  represent  a 
giraffe.  It  lies  quite  close  to  the  North  Star.  Astronomers  worked 
out  Camelopardalis  to  fill  in  a  large  area  of  the  sky  that  the 
ancient  constellations  did  not  include. 

Stars  of  the  Summer  Night 

Just  as  we  can  learn  to  tell  time  by  the  position  of  the  Big 
Dipper  constellation,  we  can  follow  the  seasons  by  tracing  certain 
stars.  In  the  summertime,  if  you  look  to  the  east  and  slightly 
north,  you  will  see  three  exceptionally  bright  stars,  located  so  as 
to  form  a  gigantic  triangle.  The  Milky  Way,  passing  through  it, 
may  help  you  to  discover  this  triangle.  The  stars  that  form  it  are 
Vega,  Altair,  and  Deneb. 

Vega,  a  brilliant  bluish-white,  is  the  brightest  star  in  the  summer 
sky.  Arcturus,  orange  in  tone,  is  second  brightest.  You  may  notice 
these  two  stars  as  darkness  falls  (Arcturus  to  the  southwest) ,  for 
they  are  the  first  to  appear.  The  three  "summer  triangle"  stars 
are  not  a  constellation;  in  fact  each  belongs  to  a  different  star 
group.  Vega  is  in  a  constellation  known  as  the  Lyre.  Altair  is  part 
of  Aquila  the  Eagle,  and  Deneb  belongs  to  Cygnus  the  Swan. 


Recognizing  the  Stars  [415 

Another  brilliant  star  you  will  find  in  the  southern  sky  of 
summer  is  Antares,  of  rosy  hue  in  contrast  to  Vega's  bluish-white. 
It  is  a  part  of  the  constellation  Scorpio.  These  and  many  other 
stars  and  constellations  will  become  sky  friends  to  look  for,  year 
after  year,  once  you  have  made  their  acquaintance. 

Winter  Stars  are  Exceptionally  Brilliant 

On  winter  evenings  the  stars  are  exceptionally  brilliant- 
brighter  than  any  "sky  pictures  of  summertime."  In  guessing  at 
the  explanation,  a  youngster  may  give  all  the  credit  to  the  clear, 
cold  atmosphere.  True,  this  clarity  is  a  help,  but  it  is  a  fact  that 
many  of  the  most  brilliant  and  striking  star  groups  come  into 
view  only  in  winter. 

Some  Wintertime  Favorites:  It  is  in  the  winter  that  we  see  the 
supergiant  star,  Betelgeuse  (bet  el  gooz) .  Early  in  the  winter  two 
bright  stars.  Castor  and  Pollux,  may  be  located  by  extending  the 
line  of  the  Big  Dipper's  handle  through  its  bowl.  Then,  through 
the  season  we  have  an  animal  parade  of  star  groups  with  the  Little 
Dog  (Canis  Minor)  and  Big  Dog  (Canis  Major) ,  and  Leo,  the 
Lion.  Many  of  the  stars  that  form  these  "animal"  outlines  are  of 
exceptional  brilliance,  including  the  Dog  Star  (Sirius)  situated 
in  the  Big  Dog,  and  Regulus,  which  marks  Leo's  heart. 

You  may  be  interested  to  know  that  Sirius  is  twenty-five  times 
as  bright  as  our  sun— though  most  of  the  effect  is  lost  on  us  as 
Sirius  is  fifty  trillion  miles  away  from  our  earth! 

If  the  clearness  of  the  winter  atmosphere  does  not  account  for 
the  variations  in  the  brilliance  of  stars,  what  then  is  the  explana- 
tion? The  distance  of  a  star  from  the  earth  is  part  of  the  story; 
but  if  all  stars  were  equally  distant  from  us  they  would  still  not 
be  equally  bright.  Some  stars  are  larger  than  others,  some  have 
a  higher  temperature  than  others.  All  these  factors  affect  the 
degree  of  brilliance  associated  with  a  given  star. 

The  Zodiac 

Millions  of  children  undoubtedly  met  this  ancient  word 
for  the  first  time  through  a  sinister  television  villain  known  as 


41 6]  Recognizing  the  Stars 

Doctor  Zodiac.  Their  parents  generally  had  a  vague  notion  that 
the  zodiac  was  concerned  with  the  heavenly  bodies,  though  many 
were  unable  to  say  just  what  it  was. 

The  zodiac  is  an  imaginary  wide  zone  in  the  sky,  within  which 
the  sun,  moon,  and  planets  move.  In  addition,  twelve  constellations 
are  considered  part  of  the  zodiac,  although  their  boundaries  may 
extend  beyond  it,  and  other  constellations  have  at  least  a  few  of 
their  stars  within  it. 

The  Signs  of  the  Zodiac:  The  twelve  zodiacal  constellations  are 
divided  into  six  northern  signs  and  six  southern  signs.  Here  they 
are,  with  their  Latin  names  and  English  translations: 

Northern  signs  for  spring:  Aries  (the  ram),  Taurus  (the  bull) , 
Gemini  (the  twins);  northern  signs  for  summer:  Cancer  (the 
crab) ,  Leo  (the  lion) ,  Virgo  (the  virgin) ;  southern  signs  for  fall: 
Libra  (the  balance) ,  Scorpio  (the  scorpion),  Sagittarius  (the 
archer);  southern  signs  for  winter:  Capricornus  (the  goat) ,  Aqua- 
rius (the  water-bearer) ,  and  Pisces  (the  fishes) . 

The  astronomers  of  ancient  times  divided  the  zodiac  into  twelve 
equal  parts,  and  we  know  these  sections  as  "the  signs  of  the 
zodiac,"  with  the  same  names  as  the  twelve  constellations  of  the 
zodiac. 

Discovering  the  Constellations 

Although  our  modem  observatories  have  to  be  equipped  with 
all  the  latest  refinements  in  the  way  of  observing,  recording,  and 
calculating,  you  can  have  the  fun  of  looking  for  the  constellations 
without  resorting  to  a  telescope. 

At  the  start  it  is  helpful  to  obtain  sky  maps  or  charts  giving 
the  positions  of  the  stars  for  the  season  in  which  you  are  in- 
terested. You  can  avoid  discouragement  if  you  are  aware  that 
even  the  ever-present  constellations  are  not  always  in  a  good  posi- 
tion for  study.  (When  they  are  near  the  horizon,  some  of  their 
stars  are  too  faint  for  you  to  see.) 

A  youngster  will  get  the  best  results,  and  hence  the  most  fun, 
seeking  constellations  that  are  high  in  the  sky.  Help  him  recognize 


THE  HEAD  OF  A  COMET  MAY  BE  LARGER  THAN  THE  EARTH 


Yerkes  Observatory— University  of  Chicago  P 


A  comet  is  a  rare  and  unforgettable  sight,  with  its  bright,  starlike  head  and  long, 
Khny  tail.  The  head  probably  consists  of  countless  small  meteorites,  and  the  tail 
of  a  rarefied  gas.  In  its  travels  around  the  sun  the  same  comet  may  become  visible 
from  the  earth  a  number  of  times,  but  centuries  may  elapse  betv/een  these  appear- 
ances in  some  cases.  The  photograph  above  is  of  Daniel's  Comet,  sighted  in   1907.

low  Astronomers  Study  the  Stars 

As  you  explain  facts  about  the  stars  to  a  child,  he  may  very 
well  be  puzzled.  Some  of  these  facts  are  so  fantastic  of  themselves, 
►ome  go  counter  to  "common  sense,"  some  contradict  what  a  child 
nay  have  taken  for  granted.  How  can  he  be  sure  that  the  informa- 
tion given  him  is  accurate— especially  as  he  learns  that  early 
studies  of  the  stars  led  to  many  incorrect  conclusions? 

Telescope  and  Camera 

It  was  the  telescope  that  gave  tremendous  impetus  to  manS 
exploration  of  the  stars.  But  his  observations  were  still  limited 
jntil  the  camera  came  along  and  considerably  enhanced  the  value 
:>f  the  telescope.  A  camera  can  be  fastened  to  the  viewing  end  of 
I  telescope,  doing  the  observer's  work  more  efficiently  in  some 
respects. 

The  combination  of  telescope  and  camera  is  particularly  effective 
kvhen  a  driving  clock  is  attached  causing  the  instrument  to  turn 
ibout  an  axis  parallel  to  the  axis  around  which  the  earth  turns. 
The  instrument  moves  at  the  same  speed  but  in  the  opposite 
iirection.  Thus  a  photographic  plate  may  be  exposed  for  several 
lours,  and  stars  too  faint  to  be  seen  through  the  telescope,  will 
register  dots  on  the  plate. 

The  Versatile  Spectroscope 

Even  before  the  camera  was  being  used  by  astronomers, 
iie  spectroscope  had  been  invented.  To  understand  how  this 
instrument  works  requires  a  knowledge  of  physics,  but  even  the 
layman  can  appreciate  the  immense  usefulness  of  this  instrument. 


^j8]  Recognizing  the  Stars 

The  spectroscope  analyzes  the  light  of  the  stars  and  reveals  what 
chemical  elements  go  into  their  make-up.  On  the  basis  of  this 
analysis  the  spectroscope  estimates  the  rate  at  which  the  stars  are 
moving,  and  the  direction  of  their  motion  toward  the  earth  or 
away  from  it. 

The  spectroscope  does  more— it  reveals  the  age  of  the  stars 
through  their  size,  color,  and  composition.  The  younger  ones  are 
giant  size  and  are  composed  of  thin  gases  that  shine  with  a  rosy 
hue.  An  older  star  is  more  condensed  and  shines  yellow.  In  the 
next  age  cycle  it  would  shine  white  and  blue;  after  that  it  is  really 
an  old  star  and  begins  to  cool. 

Through  all  its  stages  a  star  condenses  and  contracts.  After  its 
old  age,  a  star  shines  white,  then  yellow,  then  red— at  last  becoming 
cold  and  dead.  Although  a  new  star  and  a  very  old  one  both  shine 
red,  their  age  can  be  distinguished  by  their  size:  A  giant  red  star 
is  young,  a  small  red  star  is  old. 

The  Interferometer  and  Other  Aids 

Another  invention  that  has  proved  of  great  value  to  astron- 
omers is  the  interferometer,  a  remarkable  instrument  that  can  be 
attached  to  a  telescope  to  measure  the  size  of  certain  stars.  There 
are  still  other  instruments  that  help  us  to  know  the  stars.  Scientists 
use  these  instruments  to  measure  the  intensity  of  light  and  heat 
on  these  far-distant  heavenly  bodies.  Whatever  instrument  is  used, 
mathematical  techniques  are  the  key  to  success.  Geometry,  trig- 
onometry, and  the  calculations  they  involve,  originated  with  the 
measurement  of  land  on  the  surface  of  the  earth,  but  they  ended 
up  by  leading  us  to  the  stars. 

Spectacular  Sights  in  the  Skies 

The  Milky  Way— Forty  Biluon  Stars 

On  a  clear  night,  in  open  country,  even  a  child  will  be  able 
to  find  the  Milky  Way  without  having  it  pointed  out  to  him— the 
band  it  forms  in  the  sky  actually  does  have  a  milky-white  appear- 
ance. This  cloudy  band  of  light  is  made  up  of  an  enormous  number 
of  stars— an  estimated  forty  billionl— one  of  which  is  our  sun.  Many 


Recognizing  the  Stars  [419 

of  these  stars  are  too  dim  to  stand  out  separately,  but  their  light 
adds  to  the  glow  of  the  star-band.  A  number  of  important  con- 
stellations, such  as  Sagittarius  and  Cassiopeia,  are  included  in  it. 
If  you  were  to  take  a  trip  around  the  world  you  would  find 
that  the  Milky  Way  (also  called  the  Galaxy)  forms  a  nearly  con- 
tinuous belt  about  the  heavens.  At  home  you  can,  at  best,  see 
half  of  this  starry  band  crossing  the  sky  from  horizon  to  horizon. 
When  it  lies  near  the  horizon,  it  can  be  observed  only  with  some 
difficulty,  and  on  cloudy  nights,  not  at  all. 

The  Southern  Cross 

South  of  the  equator,  the  Milky  Way  includes  the  famous 
constellation  that  we  call  the  Southern  Cross  (Crux).  To  the 
people  who  live  in  the  far  south  it  is  what  the  Great  Bear  is  to 
those  in  the  north,  for  it  lies  closer  to  the  South  Pole  than  does 
any  other  outstanding  constellation.  While  the  Southern  Cross 
is  sometimes  seen  from  the  farthest  southerly  parts  of  the  United 
States,  most  of  us  know  it  from  reading  or  from  pictures. 

However,  a  picture  of  the  Southern  Cross  may  be  disappointing 
to  a  child;  the  bright,  reddish  star  (Gamma)  at  the  top  of  the 
cross  does  not  photograph  well  on  ordinary  plates  because  of  its 
color.  The  outline  of  the  Southern  Cross  is  formed  by  four  stars 
of  almost  equal  brightness.  In  the  northern  skies  we  have  a  group 
of  stars,  also  lying  within  the  Milky  Way,  which  form  a  cross  and 
are  often  called  the  Northern  Cross— though  the  official  name  for 
the  group  is  Cygnus,  meaning  "swan." 

Comets— Millions  of  Miles  Long 

Children  are  naturally  interested  in  learning  more  about 
this  amazing  spectacle  of  the  skies.  Whenever  a  comet  is  bright 
enough  to  be  seen  with  the  unaided  eye,  newspapers  make  a  big 
story  out  of  its  appearance,  and  give  the  position  in  which  the 
comet  will  be  found.  Though  astronomers  watching  the  sky  with 
telescopes  can  see  possibly  six  or  more  comets  every  year,  on  the 
average  not  more  than  two  or  three  a  century  will  be  large  enough 
to  attract  wide  attention. 


^20  ]  Recognizing  the  Stars 

What  Comets  are  Made  of:  A  comet  has  a  bright  starlike  head  and 
a  long  filmy  tail.  We  know  that  it  is  made  partly  of  solid  matter 
(as  it  reflects  sunlight)  and  partly  of  gas;  but  the  solid  matter 
does  not  form  one  great  solid  body  like  the  earth.  It  is  made  of 
many  solid  pieces  of  greatly  varying  sizes  with  gases  between  them. 

Millions  of  Miles,  Thousands  of  Years:  The  tremendous  distance 
that  separates  us  from  the  comets  makes  them  appear  small.  Ac- 
tually the  head  of  a  comet  may  be  as  big  as  the  earth,  if  not  much 
larger,  and  the  tail  is  millions  of  miles  long!  The  apparent  motion 
of  comets  through  space  is  affected,  too,  by  this  distance.  They 
seem  to  move  slowly  because  they  are  millions  of  miles  away,  but 
they  are  really  speeding  through  space.  In  the  course  of  their 
travels— which  take  them  around  the  sun  in  elongated  ellipses— 
they  may  return  a  number  of  times  within  sight  from  the  earth, 
but  hundreds  or  thousands  of  years  may  pass  between  the  suc- 
cessive appearances  of  any  one  comet. 

While  the  actions  of  most  comets  are  unpredictable,  the  famous 
"Halley's  comet"— a  bright  one  that  can  easily  be  seen  without  a 
telescope— has  been  observed  at  intervals  of  about  seventy-seven 
years.  It  was  last  seen  in  1910  and  is  predicted  to  return  about 
1987. 

A  comet  may  be  seen  with  the  naked  eye  or  with  a  telescope  for 
a  number  of  nights,  perhaps  running  into  weeks.  Each  night  its 
position  is  somewhat  changed  as  it  progresses  through  the  heavens. 

"Shooting  Stars"  are  not  Stars 

The  term  "shooting  star"  is  a  very  natural  one  for  a  bright 
spot  streaking  across  the  sky.  Astronomers  avoid  the  term,  how- 
ever, as  the  objects  that  look  like  shooting  stars  are  not  stars  at 
all.  The  proper  name  for  them  is  meteors. 

Meteors  and  "Fireballs":  Meteors  are  made  up  of  solid  material 
that  suggests  stone  or  iron.  We  do  not  know  whether  meteors  are 
fragments  left  over  from  the  forming  of  our  planets  or  matter 
that  entered  our  solar  system  from  the  outside;  but  we  do  know 
that  comets  sometimes  break  up  into  meteors. 


Recognizing  the  Stars  [  42 1 

As  it  shoots  through  the  sky,  a  meteor  may  give  off  sparks  or 
appear  to  have  a  bright  train;  and  it  may  travel  in  a  straight  or 
wavy  line.  You  are  most  likely  to  see  one  that  appears  white  or 
yellow;  but  there  are  also  very  bright  ones,  red  or  green,  and  these 
are  called  "fireballs." 

The  light  given  off  by  meteors  is  produced  by  the  terrific  speed 
at  which  they  race  through  the  atmosphere,  and  the  resulting 
friction.  Their  average  speed  is  anywhere  from  seven  to  nearly 
fifty  miles  a  second! 

"Meteor  Showers'*:  At  certain  times  of  the  year  meteors  appear  in 
such  numbers  that  we  talk  of  "meteor  showers."  You  can  look  for 
a  shower  about  the  tenth  of  December  in  the  eastern  sky;  another, 
about  the  sixteenth  of  November.  There  are  others  in  August  and 
October,  but  as  they  do  not  occur  until  after  midnight,  it  is  not 
practical  to  keep  young  children  up  to  watch  for  them. 

Two  Thousand  Meteors  a  Day:  Some  meteors  are  no  larger  than 
a  small  pea;  others  may  weigh  thirty  tons  or  more.  The  small 
ones  bum  themselves  out  by  the  friction  they  create,  but  many 
of  the  larger  ones  land  on  earth.  About  two  thousand  meteors 
hit  the  earth  every  day!  After  landing  they  are  called  meteorites. 
About  fifteen  hundred  of  them  have  been  found  (the  biggest 
weighs  fifty  tons) ,  and  a  number  of  them  are  on  exhibition  in 
museums  throughout  the  country. 

When  a  big  meteor  strikes  the  earth  it  may  smash  a  gaping  hole, 
or  crater,  in  it.  The  largest  meteor-made  crater  in  the  United 
States,  known  as  El  Diablo  (the  Devil) ,  is  in  Arizona.  It  is  more 
than  four  thousand  feet  across,  and  575  feet  deep.  For  years  pro- 
spectors have  hunted  in  vain  for  the  meteorite  that  created  El 
Diablo.  Despite  all  the  evidence  of  huge  meteorites  and  the 
discovery  of  some  big  ones,  it  does  not  seem  that  anyone  has  ever 
been  injured  by  a  meteor. 

"Flying  Saucers"— Optical  Ghosts 

The  baffling  challenge  of  unsolved  mystery  confronts  us  in 
the  provocative  reports  of  these  strange  objects  which  are  supposed 
to  have  been  seen  from  time  to  time  in  the  sky.  The  first  accounts 


422  ]  Recognizing  the  Stars 

in  1947  of  disks  hurtling  through  space  aroused  more  amusement 
than  serious  attention.  It  was  recalled  that  fifty  years  earlier, 
glimpses  of  unaccountable  "objects"  in  the  skies  were  exciting 
people,  first  in  California  and  later  as  far  east  as  Chicago.  The 
verdict  on  the  flying  saucers  was  that  they  were  not  material 
objects,  but  lights  and  reflections. 

''As  Real  as  Rainbows":  Then  came  a  new  series  of  flying  saucer 
episodes.  The  first  reports  spoke  of  round  objects— hence  the  name 
"saucer"— but  later  saucers  were  described  as  cone-shaped  and 
even  rocket-like  in  form.  Several  observers,  including  an  authority 
on  meteors,  reported  globes  of  green  fire  rushing  through  the  night 
sky  which  did  not  seem  to  be  ordinary  fireballs. 

These  accounts— and  others  like  them— started  some  astronomers 
and  the  United  States  Air  Force  on  exhaustive  investigations.  Dr. 
Donald  Menzel,  an  astronomer  and  expert  on  radar,  summed  up 
his  researches  with  the  statement:  "Flying  saucers  are  as  real  as 
rainbows." 

What  Causes  Optical  Illusions:  Behind  this  apparently  simple 
remark  are  many  complicated  facts  concerned  with  warm  and  cool 
air  currents,  and  lights  from  cars,  airplanes,  and  other  sources, 
that  make  us  see  things  when  there  are  none.  Even  children  may 
be  familiar  with  some  simple  optical  illusions.  A  common  one  is 
to  "see"  water  shining  on  a  road  that  is  actually  dry.  The  effect  is 
caused  by  a  thin  layer  of  warm  air  above  sun-heated  pavements. 
The  layer  of  hot  air  and  another,  colder  and  more  dense,  above 
it,  together  refract  (bend)  upward  the  light  that  comes  to  them 
from  the  sky;  and  it  is  this  that  gives  the  illusion  of  a  wet 
pavement. 

Other,  less  common,  types  of  mirages  may  explain  the  majority 
of  flying  saucers.  In  the  Southwest,  where  most  of  them  are  re- 
ported, atmospheric  conditions  are  especially  favorable  for  mir- 
ages, or  "optical  ghosts."  In  some  instances,  weather  balloons  or 
other  objects  have  been  mistaken  for  flying  saucers. 

Seeing  is  not  always  believing.  Our  eyes  and  nature  itself  often 
conspire  to  deceive  us.  Someday  genuine  flying  saucers,  intelli- 


Recognizing  the  Stars  [423 

gently  directed,  may  scoot  across  our  skies.  I  expect  then  that  we 
shall  be  able  to  find,  without  much  difficulty,  unmistakable,  veri- 
fiable, and  abundant  proof  that  they  are  real.  Until  evidence  of  a 
reputable  kind  is  forthcoming,  we  must  consider  the  saucers  a 
popular  fantasy,  like  the  Loch  Ness  monster,  but  still  not  close 
our  minds  to  unexpected  possibilities. 


CHAPTER 


Understanding 
the  Weather 


p 


EOPLE  ARE  ALWAYS  talking  about  the 
"  weather,  and  with  good  reason.  The 
weather  has  a  vital  bearing  on  our  plans,  our  work,  our  leisure, 
and  even  on  our  dispositions.  Weather  is  important  in  great 
and  small  things— all  the  way  from  planning  a  picnic  to  growing 
successful  crops  and  keeping  our  nation  and  the  world  well  fed. 

Children  are  even  more  dependent  than  grown-ups  on  the  state 
of  the  weather.  Clear,  sunshiny  days  mean  happy  play  out-of-doors; 
rain  often  means  the  opposite,  to  many  a  mother's  despair;  an 
abundance  of  snow  promises  endless  hours  of  merriment  on  a 
strange  and  wondrously  transformed  landscape.  So,  be  it  fair  or 
foul,  weather  is  always  a  meaningful  and  absorbing  topic  to  ex- 
plore with  children.  They  are  keenly  interested  in  it  even  before 
they  can  talk,  and  words  like  "rain"  and  "sun"  are  often  among 
the  first  they  learn. 

Later  on,  as  the  children  grow  older,  flashes  of  lightning,  claps 
of  thunder,  blizzards,  wind,  rain  and  ice  storms  give  rise  to  a 
never-ending  series  of  whys  and  hows.  They  discover  a  fascinating 
fellow  called  the  weatherman;  the  younger  ones  may  be  under  the 
impression  that  he  "makes"  the  weather,  but  the  older  ones  sagely 
pooh-pooh  this  juvenile  belief  and  ask  to  know  something  of  the 
secrets  of  weather  forecasting.

Understanding  the  Weather  [  425 

In  our  grandparents'  time  people  relied  on  various  signs  for 
hints  of  coming  weather.  Some  of  these  signs  we  still  believe  in— 
on  the  whole,  with  good  reason,  as  they  often  have  scientific  back- 
ing. Others  are  wholly  unreliable  and  have  no  such  backing; 
where  they  "work,"  the  effect  is  wholly  coincidental  and  cannot 
serve  as  a  basis  for  further  prediction.  

Ring  Around  the  Moon 

Perhaps  you  have  heard  that  "a  ring  around  the  moon 
means  rain."  This  old  belief  is  accurate  enough— rain  often  follows 
the  appearance  of  a  moon  halo.  The  big  question— and  it  is  sure 
to  come— is  why.  The  ring  indicates  that  the  moonlight  is  re- 
fracted (bent)  by  ice  particles  in  clouds  that  are  miles  overhead. 
Those  ice  particles  warn  us  of  a  change  of  temperature,  and  thus 
of  a  probable  change  in  weather. 

The  Rainbow  Has  Practical  Value 

"Rainbow  at  night,  sailors'  delight;  rainbow  in  the  morn- 
ing, sailors  take  warning,"  is  another  fairly  accurate  saying.  Rain- 
bows are  formed  when  raindrops  in  the  air  break  up  the  sunlight 
into  distinct  colors.  This  takes  place  in  the  part  of  the  sky  opposite 
the  sun.  When  you  see  a  rainbow  in  the  late  afternoon  sky,  you 
know  that  the  moisture  causing  it  is  to  the  east.  Why?  Because  the 
rainbow  must  be  opposite  the  sun,  which  is  now  in  the  west. 

Now  add  to  this  the  pertinent  bit  of  information  that  our 
storms  usually  move  from  west  to  east;  you  can  see  that  the  mois- 
ture (a  potential  storm) ,  being  already  in  the  east,  has  passed  us. 
But,  by  the  same  reasoning,  a  morning  rainbow  (in  the  west  while 
the  sun  is  in  the  east)  means  that  there  is  a  large  amount  of 
moisture  in  the  west.  As  this  comes  toward  us,  it  is  likely  to  arrive 
as  a  storm. 

Night  Rains 

"Rain  before  seven,  shine  before  eleven,"  is  likely  to  prove 
a  dependable  forecast  if  the  rain  is  light  or  moderate.  Rain  usually 
lasts  only  a  few  hours;  and  when  it  starts  in  the  cooler  hours  of 


^26  ]  Understanding  the  Weather 

the  night,  the  morning  sun  often  evaporates  the  clouds  and  stops 
the  rain.  However,  the  proverb  does  not  apply  to  heavy  storms 
that  are  often  connected  with  northeast  or  southerly  winds. 

When  the  Sun  *'Draws  Watier" 

Still  another  weather  prediction  we  can  depend  on  to  a 
certain  extent  is  that  rain  is  on  the  way  if  we  see  "the  sun  drawing 
water."  This  expression,  which  is  used  to  describe  light  rays 
streaming  toward  the  setting  sun,  is  inaccurate. 

Actually  the  rays  are  formed  by  sunlight  streaming  through 
openings  in  the  clouds  and  shining  on  vapor.  However,  as  the 
rays  appear  when  there  is  an  exceptional  amount  of  moisture  in 
the  air  and  when  the  sun  is  hidden  behind  a  cloud,  it  often  hap- 
pens that  they  precede  rainy  weather.  But  often,  of  course,  they 
do  not. 

Unreliable  Predictions 

Among  the  many  false  notions  is  the  one  that  we  can  tell 
how  many  days  will  pass  before  it  rains  by  counting  the  number 
of  bright  stars  within  a  ring  that  may  be  around  the  moon.  An- 
other entirely  incorrect  idea  is  that  whenever  the  moon  goes  into 
a  new  phase,  the  weather  changes. 

If  all  these  old  tales  were  true,  the  weatherman  could  close  up 
shop.  As  it  is,  he  has  to  stay  on  the  job  twenty-four  hours  a  day, 
using  the  most  modern  equipment  devised  by  scientists;  and  at 
that  he  cannot  be  as  certain  as  he  would  like  to  be!  But  more  of 
this  later. 

The  Wind  and  Its  Ways 

We  can  blame  most  of  our  severe  storms  on  the  wind.  Rain  is 
not  unpleasant  unless  it  is  lashed  by  strong  winds.  Snow  usually 
seems  very  beautiful— unless  wind  turns  it  into  a  blizzard.  Wind- 
storms, unaccompanied  by  rain  or  snow,  often  do  fearful  damage, 
especially  in  the  form  of  tornadoes  and  hurricanes. 

The  air  that  is  all  about  us  is  made  up  of  a  number  of  gases— 
chiefly  oxygen  and  nitrogen.  Although  we  cannot  see  these  gases. 


Understanding  the  Weather  [  427 

they  have  mass,  and  gravitation  pulls  them  downward,  giving  them 
weight.  As  a  rule  you  do  not  think  of  the  pressure  of  air  against 
your  body;  but  when  you  drive  from  mountain  heights  to  a  lower 
level  the  change  to  "heavier  air"  is  very  noticeable— especially  on 
your  eardrums. 

How  Winds  are  Formed 

For  a  number  of  reasons  we  have  high-pressure  areas,  in 
which  the  air  is  cooler  and  therefore  more  compact,  and  low- 
pressure  areas,  in  which  the  air  is  warm  and  expanded.  (One 
reason  for  this  is  that  different  portions  of  the  surface  of  the  earth 
heat  up  or  cool  off  at  unequal  rates.)  Wind  is  air  moving  from 
high-pressure  areas  to  areas  of  low  pressure— nature's  effort  to 
equalize  pressure  differences  in  the  atmosphere. 

A  high  or  low-pressure  area  may  range  from  a  few  hundred  to 
a  thousand  miles  in  diameter.  In  a  "high,"  the  pressure  increases 
steadily  toward  its  center,  and  in  a  "low"  it  gradually  decreases. 
The  speed  of  a  wind  depends  on  the  degree  of  pressure  differ- 
ence between  a  low-pressure  area  and  the  high-pressure  area  next 
to  it.  When  we  have  stormy  weather  these  variations  show  up 
sharply  on  the  weather  map  in  your  daily  newspaper;  this  is  an 
especially  good  time  to  study  the  weather  map  with  your  child. 

Why  It  Rains 

"Look  at  the  size  of  those  raindrops!"  is  an  exclamation  that  may 
start  a  child  wondering  about  why  we  have  raindrops  at  all,  and 
why  they  are  of  varying  sizes. 

The  "makings"  of  rain  are  around  us  all  the  time— tiny  droplets 
of  water  that  we  know  as  vapor  and  bits  of  water-attracting  dust. 
These  dust  particles— two  important  kinds  are  salt  from  the  sea, 
and  smoke— become  the  center  of  the  droplets  when  the  vapor  in 
the  air  takes  the  form  of  moisture.  Air  can  hold  only  a  certain 
amount  of  vapor  (warm  air  can  hold  more  than  cold  air) ,  and 
when  there  is  too  much  vapor,  the  droplets  of  water  join  together 
and  form  raindrops. 


^28  ]  Understanding  the  Weather 

How  Air  Currents  Affect  Rain:  When  the  raindrops  are  formed  in 
gently  rising  air,  the  condensation  takes  place  very  slowly  and  quite 
small  drops  may  fall  in  a  drizzle.  But  when  the  drops  are  formed 
in  powerful  upward  currents,  the  drops  may  be  held  aloft  until 
they  are  very  large  (to  a  fifth  of  an  inch  in  diameter).  This  kind 
may  fall  with  great  splashes— the  kind  you  often  see  just  before 
a  thunderstorm  downpour.  At  times  the  larger  raindrops  flatten 
out  and  split  up  as  they  fall. 

Sun  Showers:  Occasionally  we  have  the  odd  effect  of  rain  falling 
from  a  clear  sky  overhead.  This  may  be  due  to  the  drops  being 
delayed  in  their  fall  by  rising  air  currents  or  by  friction  with  the 
air.  Thus  before  the  drops  reach  us  the  clouds  from  which  they 
started  have  blown  away  or  evaporated. 

Another  curious  sight  is  rain  falling  on  one  side  of  a  street 
while  the  other  remains  dry.  This  is  simply  caused  by  small  clouds 
meeting  with  a  cold  air  current  that  turns  their  vapor  into  rain- 
drops which  fall  only  over  the  area  the  clouds  had  covered. 

A  child  may  think  of  rain  as  blowing  to  his  neighborhood  from 
great  distances— possible  from  over  the  ocean.  This  is  never  the 
case:  Rain  falls  where  it  forms.  The  moisture  may  have  been  ab- 
sorbed into  the  air  many  miles  away,  but  it  is  never  blown  to  us  as 
"ready-made"  rain. 

Billions  of  Snowflakes,  No  Two  Alike 

Probably  no  other  event  in  nature  is  so  thrilling  to  children  in 
our  latitudes  as  the  first  snowfall  of  the  season.  It  is  as  if  snow  were 
a  substance  designed  to  turn  the  humdrum  world  into  a  dazzling 
fairyland.  Observation  only  strengthens  the  fairyland  illusion,  for 
if  a  youngster  studies  a  flake  through  a  magnifying  lens,  he  notes 
that  each  snow  crystal  has  a  lovely,  delicate  design,  as  if  woven 
on  a  fairy  loom. 

Though  billions  of  snowflakes  may  fall,  no  two  are  exactly  alike 
in  design,  except  that  each  one  is  six-sided.  Some  flakes,  as  you 
can  see  with  a  magnifying  glass,  are  more  solid  than  others.  They 
are  formed  in  clouds  very  high  above  the  earth.  The  most  beauti- 


Understanding  the  Weather  [  429 

ful  flakes,  of  lacelike  design,  usually  form  in  warmer  air  currents, 
close  to  the  earth. 

Snow  and  Sleet 

"Aren't  snowflakes  frozen  water?"  your  alert  child  may 
wonder.  "What  makes  them  soft  and  white?  Why  aren't  they  little 
pieces  of  ice— like  sleet?" 

Good  questions,  these.  Snowflakes  are  frozen  moisture,  like  ice, 
but  they  are  formed  when  the  moisture  in  the  air  condenses 
(changes  from  vapor  to  liquid  form)  at  a  point  below  freezing. 
If,  on  the  other  hand,  the  moisture  condenses  into  rain  first  and 
then  freezes,  sleet  results.  The  time  when  the  freezing  takes  place 
accounts  for  the  difference. 

Snow  is  Mostly  Air 

As  the  crystal  particles  of  the  snowflake  take  shape,  many 
tiny  reflecting  surfaces  are  formed  with  air  spaces  between  them. 
It  is  these  air  spaces  that  make  snow  soft  and  dazzling  white  as 
it  reflects  the  light  of  sun  and  moon.  Also,  it  is  odd  but  true  that 
the  fluffy,  new-fallen  snow  forms  an  effective  blanket,  protecting 
whatever  it  covers  from  freezing.  (Air  is  one  of  the  best  insulators 
against  heat  and  cold.)  Newly  fallen  snow  usually  contains  only 
one  part  of  ice  to  ten  or  twelve  parts  of  air;  and  even  an  old  snow 
is  at  least  half  air. 

The  popular  theory  that  the  temperature  may  be  "too  cold  for 
snow"  is  definitely  wrong.  The  extreme  dryness  of  very  cold  air 
does  make  heavy  snow  unlikely,  but  even  then  a  warm  wind  may 
move  into  the  upper  atmosphere  bringing  moisture  with  it  and 
thus  resulting  in  snowfall. 

Frost  on  the  Windowpane 

The  appearance  of  frost  on  windowpanes  is  nature's  artistic 
announcement  of  the  arrival  of  winter.  In  many  modern  homes, 
where  storm  windows  are  used,  this  lovely  effect  is  not  so  common; 
but  sooner  or  later  most  children  have  an  opportunity  to  see  these 
exquisite  icy  window  decorations.  It  is  pleasant  to  credit  them  to 


^go  ]  Understanding  the  Weather 

the  magical  hand  of  Jack  Frost,  but  they  are  of  course  the  result 
of  low  temperatures  outside,  cold  enough  to  chill  the  indoor  air 
which  touches  the  windowpane.  (Storm  windows  protect  the  pane 
and  prevent  frost  from  forming  on  windows.) 

If  the  chill  is  sufficient  to  cause  the  moisture  to  condense  on  the 
inner  surface,  frost  begins  to  form.  Usually  crystals  first  appear 
around  some  tiny  irregularity  in  the  glass  surface  or  around  a  bit 
of  dirt.  Often  these  first  crystals  continue  to  grow,  and  as  some 
of  the  smaller  ones  evaporate,  their  moisture  condenses  again  on 
the  larger  crystals.  Thus  spectacular  designs,  numerous  and  in- 
terestingly varied,  are  created. 

How  TO  Make  Frost  Prints 

As  window  frost  rarely  lingers  more  than  a  brief  time, 
children  may  get  a  great  deal  of  pleasure  from  making  prints  of 
some  of  its  lovely  designs.  This  may  be  done  with  blueprint  paper. 
Sheets  of  this  paper,  about  twelve  inches  square,  should  be  kept 
in  a  dark  place  until  ready  for  use.  Some  morning  when  the  sun 
is  shining  brightly  though  frost  prints  have  not  yet  melted  from 
the  window,  take  a  piece  of  blueprint  paper  and  quickly  attach 
it  with  scotch  tape  to  the  pane.  Press  the  sensitive  side  directly 
against  the  frost  design  for  two  or  more  minutes. 

The  sunlight  turns  parts  of  the  paper  light  blue  but  leaves  the 
pattern  of  the  frost  in  white.  Remove  the  sheet  of  paper  and  im- 
mediately immerse  it  in  a  pan  of  clear  water  for  a  few  minutes. 
Then  transfer  it  to  another  pan  of  water  to  which  a  tablespoon  of 
peroxide  has  been  added.  When  the  blue  part  has  turned  an  at- 
tractive shade,  rinse  the  paper  in  dear  water,  then  spread  it  flat 
to  dry.  It  will  make  an  attractive  decoration  for  any  child's  room. 

Hail-*^Hot-Weather  Ice" 

To  some  people,  hail  is  "hot-weather  ice,"  as  it  is  usually  seen 
during  violent  summer  thunderstorms;  it  is  quite  rare  in  winter- 
time. Hailstones  are  formed  when  raindrops  are  caught  in  swiftly 
uprushing  air  and  are  carried  high  into  the  cloud  tops  where  they 
may  meet  snow  crystals.  Mixing  with  the  crystals,  the  raindrops 


Understanding  the  Weather  [  43 1 

become  globules  of  cloudy  ice.  These  globules  may  fall,  on  descend- 
ing air  currents,  into  warmer  rain  levels  of  air  and  take  on  a  layer 
of  ice  from  contact  with  rising  drops.  Again  the  growing  ice  pellets 
may  be  tossed  far  up,  and  again  a  layer  of  snowy  ice  will  be  added 
to  them. 

This  up-and-down  movement  may  continue  until  the  ice  pellets 
have  a  dozen  or  more  layers.  Records  show  that  hailstones  having 
twenty-five  layers,  and  as  big  as  baseballs,  once  fell  at  Annapolis, 
Maryland! 

Thunder  and  Lightning 

Many  children  are  frightened  by  thunder  and  lightning.  Their 
timidity  usually  fades  in  the  course  of  time  if  they  see  that  grown- 
ups are  undisturbed  by  storms,  and  if  they  can  understand  just 
what  takes  place  during  a  storm.  This  last,  unfortunately,  is  easier 
said  than  done. 

It  is  easy  for  a  child  to  believe  that  there  is  such  a  thing  as  air 
all  about  him,  for  he  can  often  feel  it  blow.  It  is  more  difficult 
for  him  to  understand  that  electricity  is  always  there  as  well. 
Nevertheless,  every  bit  of  dust  and  droplet  of  moisture  has  its 
charge— a  fact  closely  connected  with  lightning  flashes.  It  may 
be  enough  to  explain  to  a  young  child  that  lightning  is  electricity— 
the  same  force  that  furnishes  our  modern  lighting— but  on  a  grand 
scale.  Older  children  may  be  eager  for  more  details. 

What  Causes  Lightning 

About  the  time  a  thunderstorm  breaks,  you  may  notice  a 
wind  spring  up  as  though  from  nowhere  and  blow  toward  the 
storm.  Scientists  believe  such  currents  of  air  may  be  part  of  a  chain 
of  events  somewhat  on  this  order:  As  the  wind  blasts  its  way  up- 
ward, it  cools  and  the  vapor  in  it  is  changed  to  liquid  form.  The 
speed  of  the  rising  current  tears  apart  the  drops  of  water  that 
form.  The  fine  drops  are  carried  to  the  top  of  the  storm  cloud 
while  the  larger  drops  fall  to  lower  levels. 

Now,  it  seems  that  the  fine  drops  have  a  negative  charge,  while 
the  large  drops  are  positively  charged.  When  the  electrical  pres- 


A 92]  Understanding  the  Weather 

sure  between  these  two  parts  of  the  cloud  becomes  powerful 
enough  to  break  through  the  air  so  they  can  join  each  other,  a 
tremendous  spark— lightning— is  created. 

"Lightning"  In  a  Storage  Battery 

If  you  are  interested  in  things  electrical,  and  have  some 
simple  equipment,  you  probably  know  how  to  give  your  child  a 
dramatic  illustration  of  how  lightning  is  formed— and  thunder 
too.  All  you  need  do  is  connect  the  positive  and  negative  poles  of 
a  storage  battery  with  a  piece  of  wire.  As  the  youngster  looks  on, 
he  will  see  how  quickly  a  spark  is  created  there,  caused  by  the 
negative  particles  (electrons)  leaping  toward  the  positive  pole. 
He  will  hear,  too,  a  crackling  sound  accompanying  the  spark. 

In  just  the  same  way  the  giant  sparks  that  flash  across  the  sky 
produce  a  crackling  sound  of  tremendous  volume.  We  call  it 
thunder. 

Forked  Lightning  and  Other  Kinds 

Lightning  comes  in  different  forms.  The  most  common  type 
is  forked  lightning  with  a  brilliant  zigzag  flash,  as  the  electrical  dis- 
charge takes  the  path  of  least  resistance— an  irregular  one— through 
the  air.  A  second  kind,  "sheet"  lightning,  is  caused  by  a  flash 
hidden  in  the  clouds  which  brightly  but  briefly  lights  up  a  whole 
cloud  or  a  sheet  of  rain. 

Finally,  there  is  "heat"  lightning— a  description  we  often  give 
to  a  sudden  lighting  of  the  atmosphere  that  appears  near  the  hori- 
zon though  no  thunderclouds  are  in  sight.  Heat  lightning  is  usual- 
ly explained  as  the  reflection  of  lightning  flashes  below  the  horizon 
by  the  hazy  air  within  our  range  of  vision.  It  is  appropriately 
named  "heat  lightning,"  as  we  encounter  it  during  hot,  muggy 
weather. 

When  Lightning  is  Dangerous 

Though  we  want  to  reassure  a  child  on  the  subject  of 
lightning,  we  must  not  fail  to  let  him  know  the  circumstances 
under  which  it  can  be  a  real  danger.  Most  flashes  are  from  one 


Understanding  the  Weather  [  433 

cloud  to  another;  very  few  come  down  to  earth,  and  only  when 
the  negative  charges  in  a  cloud  are  attracted  to  positive  charges 
on  the  ground. 

Probably  the  safest  place  to  be  is  indoors  when  there  is  a  storm 
in  your  neighborhood.  If  you  happen  to  be  outdoors  and  without 
available  shelter,  be  sure  to  avoid  high  ground,  trees  standing 
alone,  the  edges  of  woods,  and  wire  fences.  In  case  the  lightning 
is  unusually  severe  and  directly  overhead,  your  safest  course  is  to 
lie  or  sit  in  a  ditch. 

How  Many  Miles  Between  You  and  Lightning? 

Most  children  enjoy  being  able  to  reckon  how  far  lightning 
is  from  them;  and  knowing  how  to  do  this  is  especially  comforting 
to  the  nervous  child  who  imagines  that  every  flash  is  directly  over 
his  head.  The  calculation  is  based  on  the  lapse  of  time  between 
a  flash  and  the  moment  the  resulting  thunder  is  heard.  So  quickly 
does  light  travel  that  the  lightning  is  seen  almost  the  instant  it 
flashes.  Therefore,  if  you  count  the  number  of  seconds  that  elapse 
between  the  flash  and  the  thunder,  you  know,  roughly,  the  distance 
between  you  and  the  storm  center. 

You  can  train  yourself  to  count  seconds  without  a  timepiece 
by  repeating  some  such  phrase  as  "storm  in  the  sky,"  which  takes 
a  second  to  say.  A  lapse  of  fifty  seconds  means  the  lightning  is 
about  ten  miles  away  (a  mile  distant  for  each  five  seconds) .  You 
cannot  hear  thunder  from  a  greater  distance  than  ten  miles,  except 
under  unusually  favorable  circumstances. 

Thunderstorms 

You  have  probably  noticed  that  there  are  different  kinds  of 
thunderstorms  and  that  they  have  different  effects  on  the  atmo- 
sphere. Moreover— contrary  to  popular  belief— they  may  even  oc- 
cur in  winter.  The  two  kinds  that  most  often  visit  us  in  summer 
are  the  local  or  "heat"  thunderstorm  and  the  "cold  front"  type. 

Heat  Thunderstorms:  The  heat  thunderstorm  is  generally  a  small- 
scale  affair  leaving  the  atmosphere  as  oppressive  as  before  it  broke. 
This  kind  is  most  common  in  the  late  afternoon  or  early  evening 


^g^  ]  Understanding  the  Weather 

following  an  extremely  hot  day.  The  overheating  of  the  surface 
air  when  the  atmosphere  is  fairly  quiet  brings  about  an  unstable 
condition,  and  the  storm  is  the  outcome. 

"Cold  Front*'  Thunderstorms:  The  "cold  front"  thunderstorm  is 
frequently  more  severe.  It  may  form  a  nearly  continuous  line 
hundreds  of  miles  long  where  cool  air  from  the  west  or  north  meets 
hot,  moist  currents.  As  a  result,  the  vapor  in  the  air  turns  rapidly 
into  water,  and  with  the  heavy  downpour  of  rain  great  electrical 
disturbances  take  place.  Such  a  storm  is  often  accompanied  by 
Wind  squalls  and  hail.  Though  it  may  break  at  any  time  of  day 
or  night,  the  most  likely  time  is  in  the  afternoon. 

l^hter  Thunderstorms:  Winter  thunderstorms,  which  usually 
.'(p?»he  at  night,  almost  always  announce  the  arrival  of  a  sharp 
change  in  the  weather.  Toward  the  close  of  a  cold  spell,  when  a 
warm  wind  blows  over  a  region,  thunderstorms  may  occur  when- 
ever there  is  a  great  contrast  between  the  cold  and  warm  air  masses. 
Or  again,  where  warm  air  currents  are  being  displaced  by  cold  air, 
thunderstorms  may  give  warning  of  the  coming  cold  wave. 

Storms  of  Violence 

Tornadoes—Several  Hundred  Miles  an  Hour 

The  thunderstorm  is  a  relative  of  the  dreaded  tornado  and 
often  accompanies  it.  The  tornado  has  a  distinctive  feature:  It 
always  includes  a  funnel-shaped  whirling  cloud.  This  terrifying 
spiral,  green  gray  to  yellowish  black,  moves  at  a  rate  of  thirty  to 
fifty  miles  an  hour,  and  within  the  tornado  itself  the  wind  moves 
at  more  than  a  hundred  miles  an  hour  I 

In  fact,  the  speed  of  a  tornado  has  been  estimated  up  to  several 
hundred  miles  an  hour;  but  since  recording  instruments  are 
destroyed  in  such  a  storm,  no  exact  records  are  available.  Fortu- 
nately, tornadoes  do  not  occur  everywhere,  and  even  in  regions 
where  they  are  apt  to  strike  they  are  infrequent.

Cyclones—A  Confusing  Term 

Many  people  use  the  term  "cyclone"  for  these  violent 
storms.  In  fact,  the  "cyclone  cellar"  is  the  common  description  of 
an  underground  retreat  used  for  escaping  tornadoes.  The  word  is 
rather  confusing,  for  to  weathermen  a  cyclone  is  a  low-pressure 
area  which  is  not  violent  and  may  extend  over  thousands  of  square 
miles.  These  cyclones  pass  over  us  every  few  days  and  generally 
cause  no  more  of  a  change  than  increased  cloudiness. 

However,  it  became  customary  to  apply  the  term  "cyclone'  to 
a  certain  type  of  storm  that  developed  about  low-pressure  centers 
in  the  Indian  Ocean.  From  this  the  usage  of  the  term  broadened 
until  it  became  identified  with  tornadoes. 

Hurricanes— Several  Hundred  Miles  Wide:  A  hurricane  is  not 
accompanied  by  a  funnel-shaped  cloud;  but  its  speed  may  reach 
1 50  miles  an  hour  and  the  width  of  its  path  is  far  greater  than  that 
of  a  tornado.  This  width  is  generally  several  hundred  miles.  Hurri- 
canes always  start  on  the  ocean. 

Forecasting  the  Weather  from  the  Clouds 

Clouds  and  Fog 

The  best  way  for  a  youngster  to  "get  the  feel"  of  a  cloud 
is  simply  to  walk  through  fog— for  fog  is  nothing  more  than  a 
cloud  in  contact  with  the  ground  or  a  body  of  water.  Once  a  child 
knows  that  cloud  and  fog  are  the  same,  his  logical  question  then 
is,  "What  keeps  some  clouds  up  in  the  sky?"  and,  "Why  don't  they 
fall  down  to  earth  like  this  one?" 

Feathery  and  Billowy  Clouds 

These  questions  are  fairly  easy  to  answer  if  we  can  forget 
that  constantly  repeated  phrase,  "floating  clouds."  Clouds  really 
do  not  float;  they  tend  to  fall  earthward.  However,  certain  forces 
act  to  prevent  their  falling.  For  example,  the  great  billowy  white 
mounds  that  we  call  cumulus  clouds  are  supported  by  the  strength 
of  ascending  air  currents.  In  the  more  feathery  ("cirrus")  type  of 
cloud  formation  we  may  see  some  of  its  moisture  fall  as  snow  or 


^o5  ]  Understanding  the  Weather 

rain;  yet  the  cloud  stays  aloft  if  conditions  favor  condensation, 
and  if  the  particles  it  has  lost  are  replaced. 

Most  clouds  are  formed  by  rising,  warm,  moist  air  that  becomes 
visible  as  billowy  masses  of  moisture  when  it  comes  in  contact 
with  the  cold  upper  atmosphere;  and  generally  this  same  process 
which  produces  clouds  counteracts  their  natural  tendency  to  fall 
earthward. 

We  get  fog  when  warm,  humid  air  meets  a  cool  surface  such 
as  that  of  a  lake  or  sea,  or  ground  which  has  rapidly  lost  the  heat 
it  absorbed  during  the  day.  As  in  the  case  of  clouds,  the  vapor 
in  the  warm  air  then  condenses  and  becomes  visible. 

How  TO  Read  the  Clouds 

Anyone,  young  or  old,  enjoys  playing  the  role  of  weather 
prophet.  While  many  factors  enter  into  the  predictions  made  by 
the  weatherman,  you  can  nevertheless  have  the  fun  of  making  rea- 
sonably accurate  forecasts  just  from  clouds.  And  because  you  are 
concerned  only  with  your  immediate  vicinity,  your  prediction  may 
be  more  successful  than  that  of  the  professional  forecaster! 

As  far  as  a  youngster  is  concerned,  the  simplest  indications  for 
clear  weather  are  high,  white  clouds,  while  dark,  heavy,  low 
clouds  point  to  bad  weather.  Long  before  people  knew  much  about 
clouds,  this  much  was  about  all  that  anyone  looked  for  in  them. 
Today,  however,  we  have  the  benefit  of  years  of  study  of  the  clouds, 
and  we  know  that  scientists  have  divided  them  into  three  general 
classes.  Each  class  has  its  own  story  to  tell  about  conditions  high 
above  the  earth. 

Spectacular  Cumulus  Clouds 

The  spectacular  cumulus  is  the  kind  of  cloud  that  children 
are  likely  to  notice  first.  Its  name,  taken  from  the  Latin  word  for 
"heap,"  is  a  good  description;  these  clouds  are  heaps  upon  heaps 
of  billowy  mounds  that  may  reach  a  height  of  several  miles!  The 
name  becomes  easy  to  remember  when  you  associate  it  with 
"accumulated." 


Understanding  the  Weather  [  437 

When  cumulus  clouds  are  glistening  white  they  are  an  indica- 
tion of  good  weather;  but  on  a  summer  afternoon  they  may  grad- 
ually darken  and  become  an  unmistakable  threat  of  a  storm- 
often  accompanied  by  thunder  and  lightning. 

Artists  are  fond  of  ornamenting  their  landscapes  with  cumulus 
clouds,  but  the  cloud  "portraits"  they  produce  are  often  decidedly 
incorrect.  They  show  the  clouds  as  rounded  masses  at  both  top  and 
bottom— whereas  the  base  of  a  cumulus  cloud  is  always  flattened. 
The  base  forms  at  the  level  where  rising  warm  air  cools  enough 
to  cause  its  water  vapor  to  condense.  Then,  if  the  current  of  rising 
air  is  strong,  the  cloud  grows  upward  with  its  rounded  head  mark- 
ing the  top  of  the  rising  air  column. 

Cirrus  Clouds— "Mares'  Tails" 

The  white  feathery  wisps  that  you  are  likely  to  see  on  a  fine 
summer  day  belong  to  a  second  cloud  group.  These  are  cirrus 
clouds  (from  the  Latin  word  meaning  "curl") .  "Cirrus"  sounds  a 
little  like  "icy,"  and  this  helps  us  remember  that  cirrus  clouds  are 
made  up  of  tiny  particles  of  ice— not  merely  moisture.  They  are 
the  highest  of  all  clouds,  and  may  range  from  two  to  seven  miles 
aloft.  As  cirrus  clouds  suggest  long  wisps  of  hair,  they  are  often 
called  "mares'  tails." 

If  cirrus  clouds  are  moving  from  the  southwest,  the  temperature 
is  apt  to  fall.  If  they  are  coming  from  the  north,  it  is  probably 
going  to  be  fair  and  warm. 

Stratus  Clouds 

Thin  flat  clouds  make  up  the  third  group,  well  named 
"stratus,"  for  this  is  the  Latin  word  for  "spreading  out."  Stratus 
clouds  do  spread  out  across  the  sky,  sometimes  as  far  as  we  can  see. 
To  remember  this  name,  think  of  the  similarity  of  "stratus"  and 
"straight."  Most  often  the  stratus  clouds  appear  as  low,  gray  sheets. 
They  may  merge  with  rain  clouds  and  precede  a  storm,  or  they 
may  clear  away  like  lifting  fog. 


^^8  ]  Understanding  the  Weather 

Other  Cloud  Forms 

''Nimbus'*  is  one  of  the  descriptive  words  that  are  fre- 
quently combined  with  the  three  cloud  forms  when  dark,  heavy 
portions  build  up  in  them.  For  example,  a  cumulus  that  grows 
black  and  threatening  is  a  cumulus-nimbus,  and  a  nimbo-stratus 
is  a  rain  sheet. 

"Alto"  ("high")  is  also  combined  with  cloud  names,  and 
"fracto"  ("broken")  is  another  element  of  cloud  descriptions. 
Add  these  terms  to  combinations  of  main  cloud  forms  like  cirro- 
cumulus  and  cirro-stratus  and  you  have  a  descriptive  name  for  all 
the  many  cloud  formations  that  decorate  the  sky.  Cirro-cumulus 
clouds  are  small  and  fleecy,  arranged  in  even  rows  high  overhead 
and  producing  what  we  often  call  a  "mackerel  sky"— a  sign  of 
coming  rain. 

How  the  Weatherman  Operates 

Young  children  sometimes  look  upon  "the  weatherman"  as  a 
very  definite  person— either  a  hero  or  a  villain,  depending  on  how 
well  the  weather  fits  in  with  their  plans.  Of  course  it  does  not  take 
long  before  they  realize  that  this  somewhat  mysterious  figure  has 
nothing  to  do  with  producing  rain,  snow,  or  sunshine— he  only 
predicts  them.  In  the  next  stage  they  begin  to  wonder  why,  when 
predictions  prove  wrong  for  several  days,  we  show  any  further 
interest  in  them. 

Forecasting  the  Weather 

We  can  understand  why  some  predictions  fail  to  materialize 
when  we  have  a  clear  picture  of  the  complex  factors  that  enter 
into  weather  forecasting.  Our  United  States  Weather  Bureau  has 
more  than  five  hundred  observers  stationed  throughout  the  entire 
country.  Every  morning  each  observer  reports  by  teletype  to  head- 
quarters in  Washington,  D.  C.  all  the  weather  facts  in  his  region 
as  recorded  on  sensitive  instruments.  These  facts  are  all  immedi- 
ately recorded  on  a  map  by  symbols. 

The  Chief  Forecaster  studies  this  map,  compares  it  with  the 
weather  map  of  the  previous  day,  and  prepares  his  predictions  for 


Understanding  the  Weather  [  439 

Washington.  Similar  forecasts  are  made  for  other  sections  of  the 
country  and  a  radio  station  in  the  Weather  Bureau  broadcasts 
them,  while  teletype  sends  them  to  airports,  newspapers,  and  com- 
mercial organizations.  A  daily  weather  map  is  also  printed  and 
widely  distributed. 

Yet,  despite  all  the  skill  and  care  of  the  experts  in  reading  signs, 
it  is  not  always  possible  to  be  certain  about  the  coming  weather. 
An  unexpected  shift  of  winds  may  blow  storm  clouds  from  an  area 
that  was  prepared  for  rain,  and  drench  another  where  sunshine 
was  expected! 

The  Weatherman's  Tools:  The  observers  who  report  to  the 
Weather  Bureau  depend  on  a  variety  of  instruments.  The  weather 
vane,  which  indicates  wind  direction,  is  the  one  with  which  most 
children  are  familiar.  More  complicated  are  the  barograph  which 
writes  down  the  pressure  of  the  air,  the  anemometer  which  mea- 
sures the  speed  of  wind,  thermometers  (of  course!),  a  very  precise 
barometer,  an  instrument  to  measure  moisture,  and  another  to 
record  sunshine.  These  tools,  and  many  others,  help  the  observers 
to  prepare  their  account  of  weather  conditions  close  to  earth. 

Studying  the  Upper  Atmosphere:  Besides  assembling  this  informa- 
tion, weathermen  have  become  increasingly  interested  in  ascertain- 
ing the  condition  of  the  upper  atmosphere.  To  obtain  this  data 
the  Weather  Bureau  sends  aloft  equipment  attached  to  a  large 
balloon.  A  radio  device  called  a  radiosonde  is  attached  to  a  para- 
chute carried  in  the  balloon.  This  instrument  is  a  small  radio 
station  in  effect,  telling,  as  it  rises,  about  the  temperature,  winds, 
and  other  conditions. 

The  information  supplied  by  the  radiosonde  is  recorded  on  a 
complicated  receiver  at  the  Weather  Bureau.  The  parachute  car- 
ries a  small  balloon  which  both  prevents  the  larger  one  from  going 
up  too  fast  and  also  helps  to  steady  it.  When  they  reach  fifteen 
hundred  feet,  the  smaller  balloon  bursts,  causing  the  remaining 
balloon  to  rise  faster— which  it  does  for  about  thirteen  miles.  Then 
the  larger  balloon  bursts— the  parachute  opens— and  the  radicK 
sonde  descends  safely. 


^40  ]  Understanding  the  Weather 

Weather  Study  as  a  Hobby 

Weather  forecasting  provides  many  hobbies  for  older  children. 
They  can  construct  instruments  for  a  weather  station  of  their  own, 
keep  records  of  their  observations,  and  study  the  weather  maps  in 
the  daily  newspaper. 

Estimating  Wind  VELOcrrv 

Besides  learning  to  know  the  clouds,  boys  and  girls  of  even 
first  and  second  grade  can  have  fun  with  weather  in  other  ways. 
While  they  may  not  be  able  to  construct  a  wind  vane,  they  can 
learn  to  describe  the  direction  of  the  wind  by  observing  where  the 
narrow,  weighted  part  of  the  vane  points. 

They  can  also  learn  to  judge  the  speed  of  wind  fairly  accurately 
without  an  instrument.  For  example:  If  smoke  is  seen  rising 
straight  up,  the  wind  is  moving  less  than  a  mile  an  hour.  If  the 
smoke  drifts  in  the  wind— though  wind  vanes  are  not  turning— its 
rate  is  from  one  to  three  miles  an  hour. 

When  wind  keeps  leaves  and  small  twigs  in  motion,  it  is  de- 
scribed as  "gentle"  and  is  traveling  from  eight  to  twelve  miles  an 
hour.  When  it  raises  dust  and  papers  and  keeps  small  branches 
moving,  it  is  "moderate"— from  thirteen  to  eighteen  miles  an  hour. 

If  you  have  trouble  walking  against  the  wind  and  it  is  bending 
trees,  it  is  "strong"— more  than  thirty  miles  an  hour.  Wind  that 
does  such  damage  as  the  uprooting  of  trees  is  a  gale,  and  may  move 
up  to  seventy-five  miles  an  hour.  A  wind  in  excess  of  this  is  a 
hurricane. 

How  to  Make  a  Rain  Gauge 

A  small  child  who  enjoys  making  things  can  construct  a  measur- 
ing instrument  for  rain  and  snow— a  rain  gauge.  The  weatherman 
uses  a  gauge  to  measure  periodic  rainfall  in  an  area,  or  the  depth 
of  water  that  would  lie  on  the  ground  if  the  rain  had  not  escaped. 

All  your  child  needs  in  order  to  make  his  own  gauge  is  a  large 
watertight  can— eight  inches  across  is  close  to  the  size  used  by  the 
United  States  Weather  Bureau.  You  can  also  make  a  measuring 
glass  by  pouring  water  to  the  depth  of  one  inch  in  the  can;  then 


Understanding  the  Weather  [441 

pour  it  into  a  tall  thin  jar  (such  as  an  olive  jar)  about  a  third  as 
big  around  as  the  can.  Mark  the  level  to  which  it  comes,  using 
permanent  paint,  and  divide  the  space  between  this  level  and  the 
bottom  of  the  jar  into  ten  equal  parts. 

Place  the  can  with  its  top  removed  on  a  stand  so  that  the  top  is 
level  and  about  two  and  a  half  feet  from  the  ground.  After  a  rain, 
pour  the  water  that  has  accumulated  in  the  can  into  your  measur- 
ing jar.  In  this  way  you  can  easily  measure  even  as  little  rainfall 
as  a  tenth  of  an  inch.  By  keeping  a  chart  for  recording  the  results 
of  each  storm,  a  youngster  has  the  added  fun  of  weather  recording. 

Studying  the  Weather  Is  More  Than  Fun 

There  is  a  real  need  among  weather  scientists  for  greater  knowl- 
edge of  local  weather  variations.  Your  child  might  even  succeed  in 
making  a  useful  contribution  to  this  field;  and,  no  matter  what 
occupation  or  profession  he  follows  in  later  life,  his  interest  in 
the  weather  will  never  leave  him.  If  his  activity  is  connected  with 
aviation  or  related  sciences,  weather  study  may  be  of  great  im- 
portance to  him.  Or— at  the  other  end  of  the  scale— he  may  merely 
want  to  know  whether  he  can  expect  clear  weather  for  taking  his 
family  on  an  outing. 

Whatever  your  child  grows  up  to  be,  his  first  experiences  as  a 
weather  recorder  or  prophet  will  be  prized  memories.  Indeed,  all 
his  happy  associations  with  the  out-of-doors— his  enjoyment  of  ani- 
mals and  his  appreciation  of  trees  and  flowers— will  be  greatly  en- 
riched if  he  has  pleasant  memories  of  a  childhood  in  which  he 
explored  the  surprises  and  delights  of  nature  with  his  parents.
