PREFACE. 


It  has  been  found  impossible  to  treat  of  the  subjects  of  metamorphism, 
elevation  of  mountains,  and  earthquakes  within  the  limits  of  this  volume, 
as  originally  contemplated,  but  we  hope  not  to  neglect  them  altogether,  as 
provision  has  been  made  for  the  printing  of  another  book,  devoted  more 
particularly  to  geology  and  mineralogy,  in  which  these  topics  will  be  fully 
discussed. 

Some  of  the  following  chapters  have  been  prepared  by  gentlemen  eminent 
in  their  several  specialties,  not  officially  connected  with  the  Survey,  who 
have  kindly  devoted  their  time  and  strength  to  the  work  without  remunera 
tion  for  their  services.  To  them  our  thanks  are  specially  extended. 

Mr.  Warren  Upham,  of  Nashua,  compiled  the  interesting  chapter  upon 
the  History  of  Explorations  among  the  White  Mountains,  and  the  descrip 
tion  of  the  river  systems.  If  the  observations  upon  altitudes  constitute  the 
most  thorough  and  perhaps  most  useful  chapter  in  the  volume,  it  is  due  to 
the  indefatigable  diligence  of  Mr.  Upham,  in  comparing  the  various  railroad 
surveys  from  different  parts  of  the  state,  sifting  out  what  seemed  unreliable, 
and  matching  them  together  into  one  connected  whole. 

With  such  substantial  foundations  established  for  the  elucidation  of  the 
water-power  of  the  state  as  are  afforded  by  these  two  chapters,  it  is  to  be 
hoped  that  the  Executive  will  call  to  mind  an  act  passed  by  the  legislature 
in  reference  to  the  appointment  of  a  hydrographic  commission.  The  infor 
mation  in  this  report  would  be  of  so  much  service  to  that  commission,  that 
the  sum  appropriated  for  their  work  would  be  sufficient  to  bring  out  results 
of  great  benefit  to  the  state,  which  could  not  otherwise  have  been  obtained 
to  so  good  advantage. 


iv  PREFACE. 

The  valuable  treatises  of  Mr.  S.  H.  Scuddcr,  of  Cambridge,  Mass.,  upon 
the  Distribution  of  Insects,  of  Dr.  A.  M.  Edwards,  of  Newark,  N.  J.,  upon 
the  Natural  History  of  the  Diatomacea?,  and  of  Mr.  W.  F.  Flint,  of  Rich 
mond,  upon  the  Distribution  of  Plants,  arc  well  adapted  to  awaken  among 
our  citizens  a  new  interest  in  the  departments  of  entomology,  microscopy, 
and  botany.  Should  this  result  follow,  the  several  gentlemen  will  feel  them 
selves  amply  repaid  for  their  exertions  in  our  behalf. 

Prof.  Quimby's  essay  upon  the  use  of  the  magnetic  needle  in  surveying 
has  been  issued  separately,  for  the  benefit  of  students  and  engineers. 

Mr.  Isaac  N.  Andrews,  of  Nashua,  has  rendered  the  appearance  of  the 
volume  more  satisfactory  by  allowing  us  the  privilege  of  copying  many  of 
the  elegant  wood-engravings,  relating  to  White  Mountain  scenery,  from  the 
White  Hills,  by  the  late  Rev.  T.  Starr  King. 

The  Atlas  will  show  very  important  contributions  to  the  study  of  our 
topography,  in  the  truthful  delineations  of  outline  sketches,  from  prominent 
points,  of  the  White  Mountains,  prepared  by  the  skilful  hand  of  Mr.  Geo.  F. 
Morse,  of  Portland,  Me.,  who  has  devoted  much  time  to  their  preparation. 

It  was  found  impossible  to  obtain  a  satisfactory  heliotype  of  the  view  of 
the  White  Mountain  range  from  Jackson,  which  was  intended  for  the  frontis 
piece.  In  its  place  we  have  inserted  the  view  illustrating  the  ledges  frac 
tured  by  frost,  upon  the  summit  of  Mt.  Washington.  For  a  similar  reason, 
the  view  of  the  White  Mountain  Notch  from  Mt.  Willard,  accompanying 
one  of  the  Willey  house,  is  copied  from  a  hand  sketch.

CHAPTER    I. 


HISTORY    OF    GEOLOGICAL    SURVEYS    IN    NEW    HAMPSHIRE. 


^ 

I  HE  first  public  notice  of  the  importance  of  examining  the  mineral 
resources  of  New  Hampshire  which  I  can  find  is  contained  in  a 
message  of  His  Excellency  Levi  Woodbury,  governor,  to  the  legislature, 
in  June,  1823.  He  recommended  the  institution  of  an  agricultural  sur 
vey,  with  a  view  to  the  chemical  analysis  of  the  various  kinds  of  soils. 
'In  support  of  this  proposal  he  quoted  the  following  passage  from  the 
constitution  of  the  state:  "It  shall  be  the  duty  of  legislators  and  magis 
trates,  at  all  future  periods  of  this  government,  to  cherish  the  interests  of 
literature  and  the  sciences."  It  also  inculcates  "the  promotion  of  agri 
culture,  the  arts,  sciences,  commerce,  trades,  manufactures,  and  the  natu 
ral  history  of  the  country."  Had  this  recommendation  been  adopted, 
New  Hampshire  would  have  been  the  first  of  the  United  States  to  inau 
gurate  a  scientific  survey  of  its  mineral  resources. 


PHYSICAL    GEOGRAPHY. 

About  1837  or  1838,  His  Excellency  Isaac  Hill,  governor,  urged  the 
propriety  of  authorizing  a  geological  and  mineralogical  survey,  with  a 
view  to  the  advancement  of  agriculture  and  the  arts.  This  was  the 
epoch  when  most  of  the  states  had  either  inaugurated  or  were  consider 
ing  the  propriety  of  establishing  geological  surveys.  Massachusetts  had 
recently  so  successfully  completed  a  triennial  survey  of  her  territory,  under 
the  superintendence  of  my  honored  father,  the  late  Professor  Edward 
Hitchcock,  that  the  utility  of  such  explorations  was  well  appreciated.  In 
1839,  His  Excellency  John  Page,  governor,  advocated  a  survey  of  New 
Hampshire  with  such  success  that  the  legislature  passed  the  following 
act  in  reference  to  it : 


AN  ACT  to  provide  for  the  geological  and  mineralogical  survey  of  the  state. 

SECTION  i .  Be  it  enacted  by  the  Senate  and  House  of  Representatives  in  General 
Court  convened,  That  the  governor  of  this  state  is  hereby  authorized  and  required,  as 
soon  as  may  be  after  the  passage  of  this  act,  to  appoint  a  state  geologist,  who  shall  be 
a  person  of  competent  scientific  and  practical  knowledge  of  the  sciences  of  geology 
and  mineralogy ;  and  the  said  state  geologist  shall,  by  and  with  the  consent  of  the 
governor  and  council,  appoint  one  suitable  person  to  assist  him  in  the  discharge  of  his 
duties,  who  shall  be  a  skilful  analytical  and  experimental  chemist. 

SEC.  2.  And  be  it  further  enacted,  That  it  shall  be  the  duty  of  the  said  state  geolo 
gist  and  his  said  assistant,  as  soon  as  may  be  practicable  after  their  appointment,  to 
commence  and  carry  on,  with  as  much  expedition  and  dispatch  as  may  be  consistent 
with  minuteness  and  accuracy,  a  thorough  geological  and  mineralogical  survey  of  this 
state,  with  a  view  to  determine  the  order,  succession,  arrangement,  relative  position, 
dip  or  inclination,  and  comparative  magnitude  of  the  several  strata  or  geological  forma 
tions  within  this  state,  and  to  discover  and  examine  all  beds  or  deposits  of  ore,  coal, 
clay,  marls,  and  such  other  mineral  substances  as  may  be  useful  or  valuable,  and  to 
perform  such  other  duties  as  may  be  necessary  to  make  a  full  and  complete  geological 
and  mineralogical  survey  of  the  state. 

SEC.  3.  And  be  it  further  enacted,  That  it  shall  be  the  duty  of  the  said  assistant  to 
make  full  and  complete  examinations,  assays,  and  analyses  of  all  such  rocks,  ores,  soils, 
or  other  substances  as  may  be  submitted  to  him  by  the  state  geologist  for  that  purpose, 
and  to  furnish  him  with  a  detailed  and  complete  account  of  the  results  so  obtained. 

SEC.  4.  And  be  it  further  enacted,  That  it  shall  be  the  duty  of  the  said  state  geolo 
gist,  on  or  before  the  first  day  of  June  in  each  and  every  year  during  the  time  necessa 
rily  occupied  by  said  survey,  to  make  an  annual  report  of  the  progress  of  said  survey, 
accompanied  with  such  maps,  drawings,  and  specimens  as  may  be  necessary  and  proper 


HISTORY    OF    GEOLOGICAL    SURVEY.  5 

to  exemplify  and  elucidate  the  same,  to  the  secretary  of  state,  who  shall  lay  such  report 
before  the  legislature. 

SEC.  5.  And  be  it  further  enacted,  That  it  shall  be  the  duty  of  the  said  state  geolo 
gist  to  cause  to  be  represented  on  the  map  of  the  state,  by  colors  and  other  appropriate 
means,  the  various  areas  occupied  by  the  different  geological  formations  in  the  state, 
and  to  mark  thereon  the  localities  of  the  respective  beds  or  deposits  of  the  various  min 
eral  substances  discovered  ;  and,  on  the  completion  of  the  survey,  to  compile  a  memoir 
of  the  geology  and  mineralogy  of  the  state,  comprising  a  complete  account  of  the 
leading  subjects  and  discoveries  which  have  been  embraced  in  the  survey. 

SEC.  6.  And  be  it  further  enacted,  That  it  shall  also  be  the  duty  of  the  said  state 
geologist  to  forward  to  the  secretary  of  state,  from  time  to  time  during  the  progress  of 
such  survey,  such  specimens  of  the  rocks,  ores,  coals,  soils,  fossils,  and  other  mineral 
substances  discovered  and  examined,  as  may  be  proper  and  necessary  to  form  a  com 
plete  cabinet  collection  of  specimens  of  geology  and  mineralogy  of  the  state  ;  and  the 
said  secretary  shall  cause  the  same  to  be  deposited  in  proper  order  in  some  convenient 
room  in  the  state  capitol,  there  to  be  preserved  for  public  inspection. 

SEC.  7.  And  be  it  further  enacted,  That  for  the  purpose  of  carrying  into  effect  the 
provisions  of  this  act,  the  sum  of  two  thousand  dollars  is  hereby  annually  appropriated 
for  the  term  of  three  years,  to  be  expended  under  the  direction  of  the  governor :  pro 
vided,  however,  that  the  salaries  of  the  said  state  geologist  and  his  assistant  shall  not 
commence  until  they  have  entered  upon  the  execution  of  their  duties,  and,  upon  the 
completion  of  said  survey  and  of  the  duties  connected  therewith,  they  shall  wholly 
cease  and  determine. 

MOSES  NORRIS,  JR., 
Speaker  of  the  House  of  Representatives. 


Approved  June  24,  1839. 

JOHN  PAGE, 

Governor. 


JAMES  McK.  WILKINS, 

President  of  the  Senate. 


In  accordance  with  the  provisions  of  this  act,  Dr.  Charles  T.  Jackson, 
-of  Boston,  was  appointed  State  Geologist  September  10,  1839,  and  en 
tered  upon  the  duties  of  the  office  June  i,  1840.  He  devoted  the  prin 
cipal  part  of  three  years  to  his  researches.  It  was  understood  and 
agreed  between  the  parties  that  the  surveyor  should  devote  four  months 
to  the  researches  required  in  the  field,  and  that  four  months  should  be 
spent  in  the  analysis  of  the  minerals  obtained  ;  but,  as  the  laboratory 
work  proved  more  difficult  and  extensive  than  was  at  first  apprehended, 
nearly  the  whole  remaining  four  months  of  the  year  were  occupied  in  the 


6  PHYSICAL    GEOGRAPHY. 

requisite  examinations.  Additional  appropriations  were  made  in  subse 
quent  years,  so  that  the  total  cost  of  the  first  survey  amounted  to  $9,000, 
independently  of  the  expense  of  publication. 

Dr.  Jackson  employed  assistants,  whose  names   and  time  of    service 
appear  to  have  been  as  follows  :  J.  D.  Whitney,  appointed  December  7, 

1840,  and  served  during   that  winter;   M.  B.Williams,  appointed  June, 

1841,  and  served  during  the  summer  of  that  year;    W.  F.  Charming, 
appointed  June  7,   1842,  and  served  during  the  summer  of   that  year 
Eben  Baker  served  in  the  autumn  and  winter  of   1842;   John  Chandler 
served  in  the  winter  of  1842.     Their  services  are  said  to  have  been  gra 
tuitous,  the  survey  paying  only  the  necessary  travelling  expenses.     Seme 
of  these  gentlemen  performed  field  work  other  than  has  been  specified,— 
which  sendee  will  be  noted  presently. 

Four  volumes  and  pamphlets  appear  to  have  been  published,  contain 
ing  an  account  of  these  researches,  as  follows  :

In  the  first  annual  report  is  described  the  method  of  proceeding  with 
the  explorations.  Knowing  that  the  strata  pursue  a  general  north-east 
course,  Dr.  Jackson  proposed  to  cross  them  several  times  at  right  angles, 
and  also  along  their  line  of  strike,  or  a  north-east  course.  These  lines  of 
explorations  would  divide  the  territory  into  triangular  areas  whose  boun 
daries  would  be  known,  and  various  excursions  across  them  would  make 
the  knowledge  of  each  tract  more  or  less  accurate.  The  cross  sections 
described  are  from  Portsmouth  to  Claremont  through  Concord ;  from  Con 
cord  to  Wakefield ;  from  Wakefield  to  Haverhill, — all  measured  by  Messrs. 
Whitney  and  Williams.  Dr.  Jackson  measured  another,  from  Concord  to 
Winchester,  traversing  outside  of  the  line  the  towns  of  Amherst,  Peter 
borough,  Dublin,  Keene,  and  Brattleborough.  Messrs.  Whitney  and 
Williams  also  travelled  to  the  northern  corner  of  the  state  as  far  as 
Mt.  Carmel ;  and  this  section  is  connected  with  a  longitudinal  section 
along  Connecticut  river,  measured  by  Dr.  Jackson  from  Haverhill  to 
Northfield,  Mass.  The  field  work  closed  after  a  tour  to  the  White  Moun 
tains,  including  Jackson,  Eaton,  and  Mt.  Gunstock. 

The  pamphlet  report  of  the  first  year's  work  contains  remarks  upon 
economical  geology  and  agriculture,  but  does  not  exhibit  any  illustrations 
of  the  sections.  Those  were  reserved  for  the  quarto  volume,  and  consist 
of  the  ones  enumerated  as  measured  by  Whitney  and  Williams,  and  the 
longitudinal  one  along  Connecticut  river  as  far  as  Mt.  Carmel  (Camel's 
Rump).  The  former  are  much  superior  in  artistic  execution  to  the  latter. 
Excepting  one  theoretical  section  and  the  geological  map,  the  material 
for  the  plates  seems  to  have  been  entirely  obtained  from  the  results  of 
this  year's  explorations. 

Second  Years  Work.  The  second  year's  explorations  commenced  at 
Nashua.  A  party  of  assistants  explored  the  southern  range  of  towns 
between  Nashua  and  Connecticut  river ;  but  they  do  not  seem  to  have 


8  PHYSICAL    GEOGRAPHY. 

furnished  any  facts  for  the  text.  Dr.  Jackson  himself  took  the  opposite 
direction,  exploring  between  Nashua  and  Portsmouth.  From  thence  he 
travelled  to  Madison  (then  a  part  of  Eaton),  Mt.  Chocorua  (Williams  and 
Channing),  Jackson,  Randolph,  Lancaster,  Shelburne,  back  to  Lancaster 
and  Dixville  notch.  Next  he  measured  a  section  through  Vermont,  from 
Lancaster  to  Lake  Champlain.  The  facts  derived  from  this  line  of  sur 
vey,  as  well  as  on  a  return  line  farther  south,  are  generalized  in  a  section, 
the  substance  of  which  I  have  reproduced  in  Fig.  I.  Meanwhile,  Messrs. 
Channing  and  E.  E.  Hale  examined  the  northern  frontier,  or  the  Canadian 
borders  of  New  Hampshire  and  Vermont.  The  rest  of  the  year's  field- 
work  consisted  of  explorations  in  Littleton,  Franconia,  Landaff,  Orford, 
Lyme,  Canaan,  Grafton,  Amherst,  and  a  hasty  trip  from  Amherst  to 
Keene. 

Third  Year's  Work.  The  third  report  states  that  the  towns  which  had 
not  been  previously  visited  were  examined  as  far  as  practicable.  Those 
mentioned  are  Epsom,  Pittsfield,  Barnstead,  Stafford,  Temple,  Richmond, 
Winchester,  Hinsdale,  Guilford,  Vt.,  Warren,  Springfield,  Enfield,  Canaan, 
Gilmanton,  Sandwich,  Jackson,  Mt.  Crawford,  Dalton,  Warren,  down 
Connecticut  river  to  Charlestown,  Unity,  and  an  excursion  to  Mt.  Wash 
ington  from  Jefferson,  by  Messrs.  Channing  and  Hale.  This  year's  report 
closes  with  a  fuller  sketch  of  the  previous  year's  work  of  measuring  sec 
tions  across  Vermont. 

BUILDING  MATERIALS,  METALLURGY,  ETC. 

The  economical  part  of  the  report  describes  granite,  soapstone,  slate, 
quartz,  limestone,  scythe-stones,  beryl,  garnet,  infusorial  silica,  ochres  for 
paints,  plumbago,  pyrites,  and  some  other  minerals.  It  is  quite  full  in 
metallurgical  statements  respecting  iron,  zinc,  copper,  lead,  tin,  silver, 
gold,  molybdenum,  manganese,  and  arsenic.  Many  original  chemical 
analyses  are  given  in  connection  with  these  economical  and  metallurgical 
descriptions. 

The  agricultural  portion  is  divided  into  five  parts  :  i.  The  origin  and 
distribution  of  soils.  2.  Nature  and  origin  of  the  organic  and  saline 
ingredients  of  soils.  3.  Chemical  constitution  of  plants.  4.  What  ingre- 


HISTORY    OF    GEOLOGICAL    SURVEY.  9 

dients  are  taken  from  the  soil  by  crops.  5.  Best  methods  of  restoring 
fertility  to  exhausted  soils,  and  of  improving  those  that  are  infertile.  It 
concludes  with  descriptions  of  the  methods  of  conducting  agricultural 
operations  by  several  eminent  gentlemen,  as  at  the  Derby  farm  on  Cow 
island,  Winnipiseogee  lake  ;  the  Shaker  farm,  in  Canterbury  ;  Levi  Bart- 
lett's  farm,  in  Warner ;  David  Stiles's  farm,  in  Lyndeborough  ;  Judge 
Hayes's  farm,  in  South  Berwick,  Maine,  and  others. 

The  barometrical  observations  are  incomplete,  and  in  a  few  cases  the 
altitudes  have  been  calculated  from  them.  All  that  are  of  value  I  have 
had  reduced,  and  given  in  a  list  of  heights  in  a  subsequent  chapter. 

The  appendix  to  agricultural  geology  contains  a  large  number  of  soil 
analyses,  mostly  original. 

GEOLOGICAL  MAP. 

The  state  authorities  did  not  think  it  important  to  color  the  geological 
map  attached  to  Jackson's  report.  Hence  it  has  become  difficult  to  un 
derstand  many  things  which  otherwise  might  have  been  evident.  Carri- 
gain's  map  seems  to  have  been  the  topographical  basis,  with,  no  doubt, 
many  corrections  of  town  boundaries  and  various  minute  points,  though 
the  mountains  are  not  reproduced.  The  scale  is  exactly  half  that  of 
Carrigain's.  The  geological  distinctions  are  the  following  :  I.  Granite, 
sienite  and  gneiss.  2.  Mica  slate.  3.  Hornblende  rock.  4.  Argilla 
ceous  slate.  5.  Drift.  6.  Alluvium.  There  are  numerous  symbols  to 
denote  the  location  of  quartz  rock,  trap,  limestone,  talc  and  soapstone, 
peat,  iron,  lead,  zinc,  tin,  copper,  pyrites,  silver,  gold,  titanium,  titanic 
iron,  plumbago,  beryl,  mica,  manganese,  arsenic,  and  molybdenum.  Other 
symbols  indicated  the  place  where  mines  or  quarries  were  worked,  the 
d-ip  and  direction  of  strata,  and  anticlinal  axes. 

JACKSON'S  THEORY  OF  GEOLOGICAL  STRUCTURE. 

These  reports  and  map  being  chiefly  descriptive  of  mineral  localities, 
it  is  difficult  to  deduce  from  them  a  very  satisfactory  notion  of  strati- 
graphical  structure.  In  general,  he  seems  to  have  regarded  the  rocks  of 
New  Hampshire  as  "  Primary,"  or  the  oldest  to  be  met  with  between

Nova  Scotia  and  Pennsylvania.  His 
ideal  section  represents  the  New 
Hampshire  rocks  as  granite  at  the 
White  Mountain  centre,  with  gneiss 
upon  both  sides,  dipping  on  the  east 
towards  Maine,  and  on  the  west 
towards  Vermont.  The  schistose 
rocks  adjacent  to  the  gneiss  in 
Maine  and  Vermont  are  called  "  Cam 
brian."  The  Green  Mountains  of 
Vermont  are  made  out  to  be  an 
immense  stratum  of  quartz  rock,  dip 
ping  westerly.  These  Cambrian  stra 
ta  in  their  turn  are  flanked  on  their 
outer  sides  by  Silurian,  and  these  in 
their  turn  by  Carboniferous  rocks,  in 
the  extremes  of  Nova  Scotia  and 
Pennsylvania. 

Not  to  be  misunderstood,  I  have 
reproduced  here  Dr.  Jackson's  ideal 
section.  I  shall  attempt  hereafter 
to  point  out  that  in  this  idea  there 
is  an  important  element  of  truth, 
while  many  of  the  details  are  incor 
rect.  It  is  true,  for  instance,  that 
in  the  White  Mountain  neighbor 
hood  the  older  rocks  make  their 
appearance.  This  view  is  derived 
from  the  study  of  the  formations  in 
the  field,  and  is  at  variance  with 
the  prevalent  opinions  of  Amer 
ican  geologists,  as  held  in  1868, 
when  our  explorations  commenced. 
The  quotation  given  in  Chapter  1 1 
shows  that  our  first  explorations 
about  Lisbon  led  to  the  conclusion 


HISTORY    OF    GEOLOGICAL    SURVEY.  I  I 

that  the  White  Mountain  series  were  older  than  those  in  the  Ammo- 
noosuc  and  Connecticut  valleys.  In  the  year  following,  1870,  Dr.  T. 
Sterry  Hunt  published  a  letter  suggesting  whether  he  had  not  been  at 
fault  heretofore  in  calling  the  White  Mountain  rocks  Paleozoic.  In  1871 
he  proposed  to  call  them  pre-Cambrian.* 

Dr.  Jackson's  section  is  wrong  in  such  details  as  these.  The  granite 
does  not  constitute  the  central  axis  of  the  White  Mountains  ;  the  strata 
are  not  regular  in  their  dips  upon  both  sides  of  the  axis,  there  being 
overturns  as  well  as  repetitions  of  older  formations.  The  Green  Moun 
tains  are  not  made  up  in  the  mass,  nor  in  any  part,  of  quartz  rock  in  the 
position  indicated,  and  the  term  Cambrian  is  misapplied. 

Territorially,  Dr.  Jackson's  oldest  division  is  made  to  occupy  the  prin 
cipal  part  of  the  state.  The  most  northern  locality  specified  is  at  Berlin. 
It  occupies  the  greater  portion  of  the  breadth  of  the  state  in  the  latitude 
of  Bristol.  South  of  this  line  there  are  only  isolated  granitic  patches 
west  of  the  Merrimack  river,  while  a  broad  band  of  it  extends  nearly  as 
far  as  Concord  on  the  east  side. 

The  mica  slate  formation  occupies  most  of  the  territory  south  of  the 
latitude  of  Franklin,  passes  up  to  Jackson  on  the  east  and  to  Columbia  on 
the  west  side  of  the  first  and  fundamental  group.  There  is  also  a  little 
represented  as  lying  upon  Mt.  Washington. 

The  third  division — "  hornblende  rock " — is  very  limited,  appearing 
only  in  Hanover,  Wakefield,  and  Acworth.  The  fourth — "  clay  slate  " — 
appears  along  Connecticut  river,  in  Hinsdale,  Chesterfield,  Dalton,  and 
Lancaster ;  on  the  east  side  of  Mt.  Washington  ;  along  Salmon  river, 
in  Rochester,  Somersworth,  Newington,  Portsmouth,  and  also  Rye. 

"  Drift "  is  shown  along  the  Merrimack  river,  in  Hudson,  Litchfield, 
Pembroke,  Northfield,  Holderness,  and  Woodstock.  It  seems  to  include 
some  extensive  sandy  plains  properly  belonging  to  the  next  division. 
"  Alluvium "  appears  in  the  same  valley  in  Concord,  and  New  Hampton, 
in  the  bend  opposite  Bristol  village  ;  also  on  the  Connecticut,  in  Hins 
dale,  Westmoreland,  Piermont,  Haverhill,  and  Lancaster.  The  localities 
of  minerals  and  ores  need  not  be  enumerated.

Museum.  I  understand  Dr.  Jackson  left  a  collection  of  rocks  and 
minerals  at  Concord  to  illustrate  his  explorations.  As  they  were  entirely 
destroyed  by  fire  a  few  years  since,  I  have  no  means  of  ascertaining  what 
their  value  may  have  been.

CHAPTER    II. 

HISTORY    OF    THE    PRESENT    GEOLOGICAL    SURVEY. 

T  the  June  session  of  the  legislature  in  1868,  the  following  statute 
was  enacted,  as  taken  from  Chapter  III,  Laws  of  1868: 

AN  ACT  to  provide  for  the  geological  and  mineralogical  survey  of  the  state. 
Be  it  enacted  by  the  Senate  and  House  of  Representatives  in  General  Court  convened: 

SECTION  i.  That  the  governor  of  this  state,  by  and  with  the  advice  of  the  honorable 
council,  is  hereby  required  and  authorized,  as  soon  as  may  be  after  the  passage  of  this 
act,  to  appoint  a  state  geologist,  who  shall  be  a  person  of  competent  scientific  and 
practical  knowledge  of  the  sciences  of  geology  and  mineralogy ;  and  said  state  geolo 
gist  shall  have  power  to  appoint  such  suitable  person  or  persons  as  he  may  deem  neces 
sary  to  aid  him  in  carrying  out  the  purposes  of  this  act. 

SEC.  2.  It  shall  be  the  duty  of  said  state  geologist,  as  soon  as  may  be  practicable 
after  his  appointment,  to  commence  and  carry  on,  with  as  much  expedition  and  dispatch 
as  may  be  consistent  with  minuteness  and  accuracy,  a  thorough  geological  and  mine 
ralogical  survey  of  this  state,  with  a  view  to  discover  and  examine  all  beds  or  deposits 
of  ore,  coal,  clay,  marls,  and  such  other  mineral  substances  as  may  be  useful  or  valua

Besides  these,  there  have  been  a  few  papers  read  by  the  state  geologist 
before  scientific  associations,  and  subsequently  published,  relating  to  New 
Hampshire  geology,  unfolding  more  fully  than  is  possible  in  the  annual 
reports  our  ideas  of  the  stratigraphical  structure  of  the  state.  In  fact, 
the  act  specially  forbids  the  presentation  of  observations  at  great  length, 
and  therefore  we  have  felt  constrained  to  make  the  reports  very  brief.  Our 
investigations  have  led  to  the  adoption  of  new  views  respecting  the  geolog 
ical  features  of  New  Hampshire,  which  seem  of  considerable  importance. 
They  will  be  unfolded  in  detail  in  the  volumes  now  in  course  of  prepara 
tion  ;  and  we  must  be  content  at  the  outset  to  give  a  short  sketch  of  the 
operations  of  the  survey,  as  set  forth, in  the  annual  reports  of  progress, 


HISTORY    OF    GEOLOGICAL    SURVEY.  15 

partly  to  trace  the  rise  of  the  doctrines  adopted  after  much  reflection, 
and  then  present  the  various  physical  features  which  lie  at  the  base  of 
sound  geological  reasoning. 

New  Hampshire,  in  her  geographical  position  and  topographical  con 
tour-features  combined,  is  unlike  any  other  portion  of  our  land;  and, 
therefore,  it  is  appropriate  to  state  at  the  outset  what  there  is  peculiar 
about  her  topography,  climate,  distribution  of  animal  and  plant  life, 
scenery,  variation  of  the  magnetic  needle,  and  other  points  in  physical 
geography.  These  involve  a  history  of  the  artificial  boundaries  of  the 
state,  notices  of  maps  that  have  been  published,  a  brief  review  of  scientific 
explorations  among  the  White  Mountains,  a  sketch  of  the  theories  relat 
ing  to  the  elevation  of  mountains,  earthquakes,  and  the  conclusions  that 
we  have  now  attained  respecting  the  physical  history  of  the  state,  or  an 
account  of  our  territorial  limits  in  the  several  periods  of  geological  time. 
This  chapter  might  be  styled  an  epitome  of  the  geology  of  New  Hamp 
shire. 

THE  FIRST  THREE  MONTHS  OF  LABOR. 

The  first  annual  report  presents  a  sketch  of  the  labors  of  three  months 
in  the  field,  and  is  not,  properly  speaking,  an  annual  report.  On  the  eighth 
of  September,  1868,  I  had  the  honor  to  receive  from  His  Excellency 
Walter  Harriman,  governor,  the  notice  of  my  appointment  as  state  geolo 
gist.  Though  almost  too  late  in  the  season  to  commence  work,  I  thought 
something  might  be  done,  and  began  the  examination  of  the  Ammo- 
noosuc  gold  field.  On  the  ninth  of  September  I  started  for  Lisbon, 
stopping  on  the  way  at  Hanover  to  arrange  for  an  office  and  storage 
apartment  for  specimens.  As  a  part  of  our  work,  invitations  were  issued 
through  all  the  newspapers  of  the  state,  to  persons  interested  in  minerals, 
to  communicate  information  and  forward  specimens  of  interesting  and 
valuable  substances  for  examination.  About  eighty  answers  have  been 
received  to  this  appeal,  from  first  to  last,  communicating  many  facts  of 
great  importance,  as  well  as  specimens.  The  great  success  of  this  circu 
lar  has  satisfied  us  that  the  community  have  been  watching  the  progress 
of  our  work  with  much  interest ;  and  that  those  who  have  been  living 
among  the  rocks  and  hills  of  New  Hampshire  will  not  be  satisfied  with  the 


!6  PHYSICAL    GEOGRAPHY. 

economical  results  of  the  survey,  but  are  anxious  to  understand  the  causes 
of  the  elevation  of  the  mountains,  of  the  immense  foldings  and  erosions 
of  the  solid  ledges,  the  filling  of  the  rock  crevices  with  metallic  ores, 
and  the  formation  of  the  soils. 

As  soon  as  possible  our  corps  of  observers  was  organized  by  the 
appointment  of  George  L.  Vose  of  Paris,  Me.,  and  J.  H.  Huntington  of 
Norwich,  Conn.,  as  assistant  geologists,  and  of  Prof.  E.  W.  Dimond  of 
Hanover,  as  chemist. 

Unforeseen  circumstances  prevented  either  of  the  geologists  from 
entering  the  field  till  the  spring  of  1869.  It  seemed  best  to  give  each  of 
them  a  special  subject,  or  a  definite  area,  to  investigate.  Accordingly  the 
White  Mountain  region  was  assigned  to  Mr.  Vose,  and  the  principal  part 
of  Coos  county  to  Mr.  Huntington.  Mr.  Vose  was  expected  to  pay  spe 
cial  attention  to  the  topography,  and,  in  addition  to  the  delineation  of  the 
geological  structure,  to  furnish  the  most  accurate  map  of  the  mountain 
region  ever  drawn. 

Inasmuch  as  Professor  Dimond  has  been  continually  occupied  by  other 
matters,  he  has  not  been  able  to  act  as  chemist  for  the  survey  at  any 
time.  His  place  in  this  respect  has  been  supplied  by  Professor  Charles 
A.  Seely,  of  New  York,  and  also,  to  a  small  extent,  by  Professor  B.  T. 
Blanpied,  of  the  New  Hampshire  College  of  Agriculture  and  the  Me 
chanic  Arts. 

The  third  month's  exploration  was  in  May,  1 869.  Its  beginning  found 
Messrs.  Vose  and  Huntington,  with  myself,  in  the  field,  engaged  in  deter 
mining  the  limits  of  the  gold  field  in  the  towns  of  Littleton,  Lyman, 
Lisbon,  Bath,  Monroe,  Landaif,  and  Haverhill.  There  has  been  little 
modification  of  the  results  attained  at  that  time,  save  in  greater  precision ; 
and  no  portion  of  our  territory  has  received  so  much  attention  as  this. 

The  report  proceeds  to  give  the  history  of  the  discovery  of  the  gold  in 
this  valley ;  a  full  description  of  the  Dodge  gold  mining  property,  with 
assays ;  a  notice  of  other  supposed  auriferous  openings,  with  an  afnrma- 
tive  answer  to  the  question  whether  it  will  pay  to  mine  for  gold  in  New 
Hampshire.  All  these  points  will  be  again  stated,  with  additions. 

In  this  pamphlet  there  appears  a  colored  geological  map  of  the  most 
interesting  part  of  the  gold  field,  in  which,  with  the  accompanying  descrip 
tions,  may  be  discerned  the  germ  of  our  peculiar  notions  respecting  the 


HISTORY    OF    GEOLOGICAL    SURVEY.  I/ 

structure  of  all  New  England.  A  portion  of  the  map  was  enlarged,  and 
hung  upon  the  wall  of  a  room  at  the  state  house,  near  a  case  of  speci 
mens,  where  those  who  were  interested  in  the  subject  could  judge  of 
the  correctness  of  the  conclusions. 

The  description  states  that  "there  are  two  general  divisions  upon  the 
map :  first,  the  granitic  and  gneissic  rocks,  ivliicli  appear  to  be  older,  and 
consequently  to  underlie  the  formations  of  the  second  or  Quebec  group? 
Explanation  is  then  made  of  the  term  "Quebec  group,"  and  its  use  in  the 
sense  in  which  it  was  proposed  by  Sir  W.  E.  Logan  stated  to  be  "provi 
sional,  and  liable  to  amendment  after  further  explorations  shall  have  made 
our  knowledge  more  definite." 

The  historical  importance  of  the  description  of  the  map  leads  me  to 
quote  it : 

A  mere  glance  at  the  map  and  accompanying  section  suggests  two  conclusions : 
First,  there  is  an  unusual  expansion  of  the  area  occupied  by  the  gold  rocks  north  of 
Haverhill,  which  contracts  to  some  extent  in  the  latitude  of  Littleton.  The  narrowest 
part  of  the  group  can  be  seen  by  referring  to  the  Vermont  Geological  Map,  and  notic 
ing  the  contracted  band,  not  three  miles  wide,  along  Connecticut  river.  It  is  not  over 
four  miles  wide  in  any  part  of  its  course  between  Lebanon  and  Woodville. 

Second,  the  rocks  assume  the  form  of  a  basin  or  synclinal  axis.*  To  confirm  this 
view,  appeal  is  made  to  the  general  arrangement  of  the  several  groups.  In  the  centre 
is  the  auriferous  conglomerate,  with  some  of  the  upper  schists.  These  are  inclosed  by 
a  line  of  dolomite,  not  represented  upon  the  map ;  this  by  clay  slate  ;  the  slate  by  the 
lower  green  schists  which  occupy  the  outer  edge  of  the  basin,  and  adjoin  the  gneissic 
rocks  of  the  White  Mountains  upon  the  east,  and  the  calciferous  mica  schist  or  supposed 
upper  Silurian  strata  on  the  west  in  Vermont.  Hence  the  strata  in  the  centre  of  the 
field,  the  conglomerate,  slates,  and  upper  schists  lie  at  the  summit  of  the  series,  and 
were  the  latest  formed.  A  few  words  about  each  sub-division. 

1 .  Gneissic  and  Granitic.     These  rocks  consist  of  gneiss  passing  into  mica  schist 
and  granite.     They  continue  easterly  from  the  gold-field  past  the  White  Mountains  into 
Maine.     By  way  of  geographical  convenience,  they  may  be  called  the  White  Mountain 
series.     The  line  of  union  is  irregular,  and  the  bordering  rock  is  not  uniform.     In  Lit 
tleton  it  is  generally  granitic ;  in  Lisbon,  gneissic ;  more  quartzose  in  Haverhill.     A 
bed  of  limestone  skirts  the  border  in  Lisbon,  and  its  place  seems  to  be  taken  by  soap- 
stone  in  North  Haverhill. 

2.  Staurolite  Rock.     Adjoining  the  gneiss,  and  apparently  resting  upon  it,  is  a  slate 
or  schist  (according  to  locality)  filled  with  crystals  of  the  mineral  staurolite,  called 

*  Shown  also  farther  north. —  Geology  of  Vermont, p.  521. 
VOL.  I.       3 


jg  PHYSICAL    GEOGRAPHY. 

staurotide  in  the  older  mineralogies.  Garnets  are  also  present.  This  rock  has  not 
been  seen  out  of  Lisbon  and  Landaff,  and  that  which  lies  in  Landaff  is  chiefly  garnet- 
iferous.  More  labor  is  required  to  fix  the  limits  and  proper  relations  of  this  rock.  At 
almost  any  outcrop  good  specimens  of  staurolite  may  be  obtained  in  abundance. 

3.  Next  are  Argillaceous  Schists,  passing  into  clay  slate.     This  rock  differs  from  clay 
slate  farther  west,  and  receives  no  color  on  the  map  to  separate  it  from  the  next  divi 
sion.     A  line  drawn  from  the  south  branch  of  the  Ammonoosuc  in  Lisbon  to  the 
east  line  of  Bath  shows  its  western  border.     It  may  contain  garnets  and  staurolite,  and 
carries  quartz  veins  worthy  of  examination  for  gold. 

4.  Lower  Sc/iists.     These  belong  to  the  lower  part  of  the  Quebec  group.     They  are 
chiefly  a  greenish,  unctuous  schist,  sometimes  massive,  the  same  with  that  usually  called 
"  talcose  schist."    As  the  unctuous  character  seems  to  be  derived  from  the  alumina 
present,  we  shall  often  style  them  aluminous  schists.     Marked  varieties  occur  over  the 
wide  area  representing  this  division,  as  hornblende  and  chlorite  schist,  greenish  quartz- 
ites,  sandstones  and  conglomerates,  white  quartz,  etc.     Within  it  are  beds  of  dolomite, 
limestone,  buhrstone,  the  copper  belt,  and  veins  of  iron  pyrites.     It  would  seem  as  if 
there  were  an  anticlinal  axis  in  the  west  part  of  the  area  of  this  group,  followed  by  a 
synclinal  in  the  east. 

5.  Clay  Slate.     This  rock  is  abundant  in  the  central  part  of  the  series,  and  carries 
the  gold  veins  akin  to  the  Dodge  lead.     That  which  lies  in  Bath  is  often  grayish.     Its 
distribution  is  quite  irregular,  and  there  are  several  patches  of  it,  apparently  outliers, 
in  two  of  which  are  slate  quarries.     The  dolomite  next  the  conglomerate  is  frequently 
imbedded  in  this  dark  slate.     In  the  more  northern  part  of  the  dolomite,  the  rock  is 
more  schistose. 

6.  Auriferous  Conglomerate.     An  immense  number  of  facts  of  scientific  interest  in 
regard  to  this  curious  belt  have  been  obtained,  but  their  publication  must  be  deferred. 
The  rock  is  a  clear  quartz  conglomerate,  from  ten  to  one  hundred  feet  wide,  extending 
from  the  east  part  of  Lyman  into  Bath.     As  it  can  be  readily  recognized,  and  resists 
decomposition,  it  furnishes  an  excellent  landmark  by  which  one  can  discover  the  won 
derful  foldings,  overturns,  and  dislocations  in  the  strata.     Instead  of  following  a  straight 
course,  its  line  of  outcrop  is  sharply  tortuous,  and  a  fault  has  often  thrown  the  rock  out 
of  its  line,  in  one  case  a  distance  of  eleven  hundred  feet.     These  variations  are  shown 
in-the  large  manuscript  map  spoken  of  above,  and  on  the  printed  map,  as  well  as  the 
scale  will  permit,  by  the  red  line.     That  this  rock  overlies  the  slate,  is  shown  by  the 
general  synclinal  character  of  the  country,  and  its  encirclement  by  the  clay  slate  which 
both  accommodates  itself  to  the  very  tortuous  course  in  Bath,  and  dips  beneath  it  on 
the  east,  south,  and  west  sides.*     That  it  overlies  the  lower  schists  seems  proved  by  the 
presence  in  it  of  pebbles  of  quartz  containing  chlorite,  jasper,  and  buhrstone,  all  of 
which  have  been  observed  exclusively  in  that  member. 

7.  Upper  Schists.     These  are  partly  very  light  colored,  and  partly  quite  siliceous  as 

*  This  view  has  been  modified  by  later  researches. 


HISTORY    OF    GEOLOGICAL    SURVEY.  19 

well  as  unctuous.     They  bound  the  clay  slate  on  the  west  side,  near  the  Dodge  mine  ; 
while  near  their  eastern  limit  is  the  auriferous  quartz  vein  described  as  the  property 
of  the  New  Hampshire  Gold  Mining  Company.      The  color  and  aspect  of  this  group 
change  in  proceeding  southerly. 
8.  The  Copper  Belt. 

Upon  the  map  is  a  section  from  Branson's  lime-kiln  to  the  Connecticut 
river,  near  Stevens  village,  in  Barnet.  The  dips  and  general  arrangement 
are  the  same  with  what  will  be  described  hereafter.  Two  faults  are  rep 
resented,  whose  extent,  but  not  existence,  may  be  somewhat  modified  in 
future  descriptions. 

Copper  Mines.  Next,  a  considerable  space  is  devoted  to  a  description 
of  numerous  copper  veins,  chiefly  along  Gardner's  Mountain  range.  The 
general  conclusions  then  reached  have  been  confirmed  by  subsequent 
researches.  Only  the  conclusions  need  be  referred  to  in  this  sketch,  as 
the  details  will  be  given  hereafter. 

In  brief,  it  may  be  said  of  the  Gardner  Mountain  range  of  copper  veins, 
that  they  consist  of  schists  charged  with  the  sulphurets  of  iron  and  cop 
per,  averaging  less  than  five  per  cent,  before  concentration  ;  that  they  are 
conveniently  situated  with  respect  to  drainage  and  to  water-power.  As 
several  mines  are  contiguous,  adits,  mills,  and  tramways  might  be  con 
structed  for  the  mutual  benefit  of  several  proprietors,  with  a  comparatively 
small  proportionate  outlay  for  each.  It  was  understood  that  some  of  these 
proprietors  had  arranged  for  the  concentration  of  the  ores  at  the  new  mills 
soon  to  be  constructed  in  the  west  corner  of  Lisbon.  The  working  of 
these  copper  veins,  if  conducted  with  prudence  and  wisdom,  will  undoubt 
edly  be  remunerative  ;  and  when  the  enterprise  is  fairly  inaugurated,  a 
large  number  of  workmen  will  be  employed,  and  a  new  impetus  given  to 
the  industry  of  the  whole  community. 

Miscellaneous  Topics.  Other  topics  treated  of  were  the  zinc  or  copper 
mine  at  Warren  ;  the  nature  and  extent  of  peat  deposits  ;  an  enumeration 
of  beds  of  limestone  suitable  for  manufacture  into  quick-lime ;  agricultural 
deductions  for  the  Coos  region ;  economical  statistics  and  statements 
about  the  museums.  Great  interest  in  the  survey  among  the  people  was 
also  spoken  of.  This  manifested  itself  very  pleasantly  in  acts  tending  to

forward  our  researches.  Some  hotel  proprietors  refused  to  accept  of 
compensation  for  accommodation  received  ;  others  reduced  the  ordinary 
rates  for  our  benefit ;  many  occupants  of  private  houses  freely  tendered 
their  hospitalities  ;  some  have  gone  with  us  to  point  out  localities  of 
interest ;  and  for  six  weeks  so  many  carriages  were  placed  at  our  disposal 
that  there  was  no  occasion  to  hire  a  team.  Every  one  with  whom  we 
came  in  contact,  from  highest  to  lowest,  expressed  an  interest  in  our 
work,  and  no  one,  to  our  knowledge,  spoke  of  it  disparagingly.  These 
many  favors  greatly  stimulated  us  in  our  work.  Acknowledgment  was 
also  made  of  the  important  aid  furnished  by  the  newspapers.  They 
promptly  circulated  our  original  appeal  for  aid,  and  have  always  been 
ready  to  help  us  subsequently. 

The  authorities  of  Dartmouth  college  generously  provided  rooms  to 
serve  as  an  office  and  working  apartment,  as  well  as  for  the  exhibition 
and  storage  of  specimens,  till  a  building  could  be  erected  for  their  accom 
modation.  Lastly,  a  few  names  of  individuals  were  given  who  had  ten 
dered  us  special  courtesies. 

SECOND  ANNUAL  REPORT. 

This  continues  the  history  from  June  I,  1869,  for  one  year.  It  com 
mences  with  statements  respecting  the  importance  of  a  new  topograph 
ical  map  of  the  state,  that  might  serve  for  the  proper  delineation  of  the 
geological  boundaries.  One  of  the  first  inquiries  made  at  the  beginning  of 
the  New  Hampshire  explorations,  related  to  the  character  of  the  maps  in 
use,  that  I  might  learn  with  how  great  precision  the  position  and  courses 
of  the  several  mineral  veins  and  rock  deposits  could  be  delineated.  I 
found  that  a  map  had  been  issued,  under  the  authority  of  the  state,  in  1 8 1 6, 
by  Philip  Carrigain.  This  seems  to  have  been  a  very  fair  delineation  of 
the  natural  and  civil  boundaries  at  the  time  of  its  appearance.  But  there 
are  serious  errors  in  it  of  latitude  and  longitude.  Nearly  half  the  boun 
dary  lines  have  since  been  altered,  whether  of  the  towns,  or  the  limits 
between  adjoining  territories;  and,  moreover,  the  plates  are  not  to  be 
found.  Then  the  whole  face  of  the  country  has  been  altered  since  1816; 
large  tracts  of  forest  have  been  reclaimed  and  occupied  by  village  sites ; 
numerous  roads  and  railroads  have  been  constructed, — so  that  Carrigain's 
map  does  not  meet  the  necessities  of  either  practical  or  scientific  pur- 


HISTORY    OF    GEOLOGICAL    SURVEY.  21 

poses  at  the  present  day.  There  have  been  smaller  maps  also  constructed, 
most  of  which  are  inferior  to  Carrigain's  for  accuracy,  as  they  certainly 
are  in  the  style  of  execution. 

Besides  this,  other  map  material  exists.  There  are,  first,  the  county 
maps,  prepared  chiefly  by  Prof.  H.  F.  Walling,  at  an  expense  of  over 
$20,000.  These  present  the  roads  with  great  accuracy,  and  likewise  the 
names  of  the  owners  of  every  house  at  the  time  of  the  surveys.  Being 
on  a  large  scale,  and  published  mostly  about  1860,  the  boundaries  and 
names  agree  essentially  with  what  they  are  at  present,  and  the  surveys 
were  quite  accurate.  Secondly,  a  considerable  triangulation  has  been 
effected  by  the  United  States  Coast  Survey  over  fully  a  third  part  of  the 
state.  By  means  of  their  triangles  a  score  or  more  points  are  definitely 
fixed  in  respect  to  latitude  and  longitude,  and  that  as  correctly  as  is  pos 
sible,  through  the  unequalled  accuracy  of  the  Coast  Survey  engineers. 
Thirdly,  there  exists  a  very  careful  delineation  of  the  boundary  between 
New  Hampshire  and  Canada,  prepared  in  1 844,  under  the  direction  of  the 
governments  of  the  United  States  of  America  and  Great  Britain,  Colonel 
Graham  being  the  commissioner  on  the  part  of  the  United  States.  Lastly, 
there  are  the  reports  of  commissioners  concerning  the  boundaries  between 
New  Hampshire  and  Maine,  between  New  Hampshire  and  Massachusetts, 
and  there  are  two  local  maps  of  the  White  Mountain  region,  all  of  which 
are  accessible. 

On  further  inquiry  it  was  ascertained  that  in  1853  the  legislature 
appointed  a  commissioner  to  report  upon  the  expediency  of  preparing  a 
new  topographical  map  of  the  state.  The  report  was  presented  the  fol 
lowing  year  by  Prof.  John  S.  Woodman,  of  Hanover,  who  briefly  recited 
the  errors  in  Carrigain's  and  other  maps,  and  carefully  estimated  the 
expense  of  preparing  a  new  draft  based  upon  the  government  work  just 
alluded  to,  and  upon  new  surveys.  He  showed  that  such  a  map  would 
involve  an  expense  of  thirty  or  forty  thousand  dollars.  No  action  was 
taken  upon  this  report  by  the  legislature. 

It  appeared  to  me  that  the  chief  part  of  the  surveys  requisite  for  the 
proper  delineation  of  a  new  map  of  the  state  had  been  made  since  1854, 
so  that  by  a  careful  collation  of  the  abundant  material,  coupled  with  some 
additional  triangulation  and  river  surveys,  a  new  map  might  be  prepared, 
sufficiently  accurate  for  all  practical  purposes,  which  would  require  a  very

small  appropriation  compared  with  the  sum  estimated  by  the  commis 
sioner  in  1854.  A  letter  was  accordingly  addressed  to  His  Excellency 
the  Governor,  and  the  Honorable  Council,  in  which  the  foregoing  facts 
were  recited,  and  the  proposal  was  made  that,  without  asking  for  any 
additional  appropriations,  the  geologist  would  cause  a  new  map  of  the 
state,  upon  the  scale  of  two  and  a  half  miles  to  the  inch,  to  be  prepared, 
and  that  this  work  might  be  considered  as  involved  in  the  act  authorizing 
the  survey.  The  council  approved  of  this  proposition  May  13,  1869;  and 
since  that  time  measures  have  been  taken  to  prepare  the  map,  in  connec 
tion  with  the  other  work. 

TOPOGRAPHICAL  WORK  PP:RFORMED. 

The  most  important  topographical  work  performed  this  year  is  embodied 
in  a  report  by  Prof.  E.  T.  Quimby,  of  Dartmouth  college,  most  of  which 
is  presented  in  the  chapter  upon  topography. 

Next  should  be  mentioned  the  labors  of  Mr.  Vose.  He  spent  a  few 
weeks  among  the  White  Mountains,  taking  a  large  number  of  observa 
tions  for  the  purpose  of  fixing  the  exact  position  of  many  of  the  high 
mountain  peaks.  His  observations  serve  to  fix  the  latitudes  and  longi 
tudes  of  Mt.  Passaconnavvay,  Waterville;  Mt.  Pequawket,  Chatham;  Mt. 
Whiteface,  Waterville ;  and  Mt.  Chocorua,  Albany.  From  Mts.  Pequaw 
ket  and  Chocorua,  Mr.  Vose  drew  accurate  sketches  of  all  the  mountains 
as  seen  along  the  New  Hampshire  horizon.  The  instrument  used  was  a 
six-inch  theodolite,  kindly  loaned  for  the  purpose  by  the  United  States 
Coast  Survey.  Mr.  Vose  also  made  observations  upon  the  geology  of 
the  region,  which  were  mostly  printed  in  the  report  for  1871.  In  the 
month  of  August  he  resigned  his  position  on  the  survey. 

During  all  the  seasons  of  field  work  our  parties  have  been  supplied 
with  county  maps,  and  have  carefully  noted  the  changes  or  alterations 
required  for  the  perfection  of  the  general  map.  These  will  be  embodied 
upon  our  large  geological  map.  For  the  sake  of  determining  the  forma 
tions  in  the  Ammonoosuc  gold  field  with  accuracy,  we  commenced  during 
this  season  a  topographical  survey  of  a  few  square  miles  of  the  most 
valuable  portion,  upon  the  scale  of  five  hundred  feet  to  the  inch.  With 
the  aid  of  J.  H.  Huntington,  A.  C.  Page  of  Center  Harbor,  and  A.  A. 


HISTORY    OF    GEOLOGICAL    SURVEY.  23 

Woolson  of  Lisbon,  two  square  miles  of  the  territory  were  surveyed. 
The  intention  was  to  set  stakes  at  the  corners  of  every  block  of  five 
hundred  feet  square,  and  thus  to  locate  the  formations  with  great 
definiteness. 

At  the  request  of  the  commissioners  appointed  to  consider  the  propri 
ety  of  establishing  a  survey  of  the  water-power  of  New  Hampshire,  we 
prepared  a  map  of  the  state,  upon  the  scale  of  ten  miles  to  the  inch, 
showing  by  colors  the  areas  drained  respectively  by  the  Connecticut, 
Androscoggin,  Saco,  Piscataqua,  and  Merrimack  rivers.  It  was  compiled 
from  our  data  by  Mr.  Huntington.  The  map  accompanied  the  report  of 
the  hydrographic  commissioners.  A  copy  from  the  same  plate,  with 
changes  and  additions,  was  presented  with  our  second  report,  designed 
to  illustrate  the  distribution  of  the  granite  and  the  progress  of  our  trian- 
gulation,  as  well  as  some  of  the  geological  formations. 

MEASURING  HEIGHTS. 

In  May,  1870,  a  trip  was  taken  by  Mr.  Huntington  to  determine  the 
relative  altitudes  of  the  passes  along  the  principal  White  Mountain  range 
between  the  Crawford  house  and  Waterville.  The  snow  had  not  entirely 
disappeared,  so  that  the  expedition  was  of  a  very  laborious  character. 
The  results  are  given  elsewhere. 

A  thorough  knowledge  of  the  general  elevation  of  the  land  of  the  state 
being  very  important,  measures  were  taken  early  towards  the  obtaining 
of  exact  altitudes  in  the  interior.  Upon  examining  various  railroad 
surveys,  discrepancies  appeared,  so  that  they  could  not  be  relied  upon. 
Two  lines  of  survey  running  lengthwise  of  the  state  were  therefore 
devised, — one  from  Portsmouth  (or  Great  bay)  through  Manchester,  Con 
cord,  and  the  Connecticut  valley  to  Connecticut  lake ;  the  other  from 
Lowell,  Mass.,  to  connect  with  the  other  survey  at  Lancaster.  The 
final  conclusions  appear  in  another  chapter;  but  the  work  was  com 
menced  early  in  the  second  season.  Messrs.  Frank  and  H.  D.  Wood- 
bridge,  of  Dartmouth  college,  obtained,  by  actual  levelling  much  of  the 
way,  facts  which  fixed  the  height  of  the  barometer  at  the  Shattuck  obser 
vatory,  in  Hanover,  at  603.71  feet  above  mean  tide-water.  A  few  com 
putations  were  made,  also,  by  a  comparison  of  barometical  observations 
at  the  Shattuck  observatory,  and  the  top  of  Mt.  Moosilauke.

MOUNTAIN  EXPLORATIONS. 

During  the  second  year,  the  Moosilauke  winter  exploration  was  carried 
out  by  J.  H.  Huntington  and  Amos  F.  Clough.  This  is  sketched,  as  fully 
as  needed  for  our  purposes,  in  the  chapter  upon  the  history  of  explora 
tions  among  the  White  Mountains. 

Possibly  there  may  be  space,  in  the  chapters  upon  scenery,  to  quote 
from  Mr.  Vose's  report  upon  an  ascent  of  Mt.  Carrigain,  made  during 
this  year. 

MEASURING  SECTIONS. 

In  a  letter  directed  to  Rev.  Dr.  Asa  D.  Smith,  President  of  the  New 
Hampshire  College  of  Agriculture  and  the  Mechanic  Arts,  and  printed  in 
his  report  for  1 869,  I  set  forth  my  views  as  to  the  best  method  of  exhib 
iting  the  specimens  of  rocks  collected  during  our  explorations.  It  was  sug 
gested  that  these  should  be  collected  along  lines  about  fifteen  or  twenty 
miles  apart,  running  east  and  west,  and  parallel  to  one  another,  amounting 
to  fourteen  in  number  in  all.  These  lines  were  called  lines  of  section, 
because  it  was  proposed  to  show,  in  connection  with  the  specimens,  a 
geological  profile  and  section.  This  method  of  studying  the  geological 
structure  of  the  state  readily  commends  itself  to  every  mind. 

We  crossed  the  state  eight  times  during  this  season  in  endeavoring  to 
measure  these  sections.  The  lines  of  section  thus  measured  are, — 

I.  From  Lawrence,  Mass.,  along  the  south  border  of  the  state,  to  Con 
necticut  river. 

II.  From  Seabrook  to  Chesterfield. 

III.  From  Portsmouth  to  Walpole. 

IV.  From  Great  Falls  to  Charlestown. 

V.  From  Milton  to  Cornish. 

VI.  From  Effingham  to  Hanover. 

VII.  From  Errol  to  Stratford. 

VIII.  From  Atkinson  and  Gilmanton  Academy  grant  to  Stewartstown. 
The  last  two  were  traversed  by  Mr.  Huntington  on  foot,  as  they  lie 

chiefly  in  the  unbroken  forest.     Two  sets  of  specimens  have  been  col 
lected  along  these  routes. 


HISTORY    OF    GEOLOGICAL    SURVEY.  25 

EXAMINATION  OF  Coos  COUNTY. 

One  of  the  most  laborious  parts  of  our  work  accomplished  this  year 
has  been  the  exploration  of  about  six  hundred  and  seventy  square  miles 
of  territory,  in  the  north  part  of  Coos  county,  by  Mr.  Huntington.  The 
country  is  mostly  unsettled,  and  consequently  travelling  is  restricted  to 
the  most  primitive  methods,  and  all  supplies  are  carried  on  one's  back. 
The  same  is  true  of  all  specimens  collected,  which  were  at  least  a  thousand 
in  number,  from  the  forest  region.  But  the  information  acquired  has  been 
most  important.  As  will  be  seen  by  the  map,  the  line  has  been  clearly 
drawn  between  the  White  Mountain  series  of  granitic  or  gneissic  rocks, 
and  the  dark  slates  and  schists  of  newer  formations.  The  latter  are 
sub-divided  into  eight  different  bands,  and  a  county  map  has  been  col 
ored  to  show  them.  Two  matters  of  economical  interest  have  been 
developed, — the  first,  the  existence  of  alluvial  gold  along  Indian  and  Perry 
streams ;  and  the  second,  the  existence  of  large  beds  of  serpentine  north 
of  Carlisle's  grant,  a  few  miles  south-west  from  the  crown  monument,  at 
the  angle  between  New  Hampshire,  Maine,  and  the  province  of  Quebec. 
The  latter  is,  of  course,  too  remote  to  be  available  for  the  arts  at  present, 
though  the  time  is  coming  when  it  will  be  used.  The  gold  is  not  unlike 
that  of  Lyman,  judging  from  the  character  of  the  underlying  rocks,  but 
more  closely  resembles  that  mined  a  short  distance  over  the  line,  where 
J.  H.  Pope,  member  of  parliament,  of  Cookshire,  province  of  Quebec,  has 
been  profitably  extracting  gold  by  sluices  for  several  years.  Mr.  Hunt- 
ington's  specimens  are  quite  large  pieces  of  shot  gold,  of  the  same 
purity  with  that  obtained  by  milling  in  Lisbon.  It  is  not  improbable 
that  the  gold  can  be  profitably  extracted  both  from  the  soil  and  the 
rock  near  the  extreme  northern  boundary;  and  the  proprietors  of  the 
large  tracts  of  land  there  would  do  well  to  expend  a  few  hundred  dollars 
in  testing  the  value  of  these  auriferous  deposits. 

MISCELLANEOUS. 

There  are  further  remarks  upon  the  agricultural  character  of   lands 
along  Connecticut   river;    operations  of    the   gold   mining  company  in 
Lyman  and  Lisbon ;  notice  of  Mr.  Vose's  report ;  the  Carroll  county  lead

mine ;  other  mining  properties,  particularly  beds  of  pyrites  in  Croydon, 
Unity,  Lebanon,  etc. ;  G.  A.  Wheelock's  researches  about  Kccne ;  various 
brief  excursions ;  and  the  map  of  Dalton. 

It  was  stated  in  the  first  report  that  very  material  aid  might  be  fur 
nished  us  in  our  explorations  if  the  proprietors  of  large  tracts  of  land 
would  aid  us  in  tracing  out  the  formations  upon  lands  in  which  they  feel 
an  interest.  This  appeal  was  immediately  answered  by  J.  13.  Sumncr, 
Esq.,  of  Dalton,  who  furnished  the  means  for  a  careful  survey  of  the 
township  of  Dalton.  The  work  was  performed  by  Mr.  Huntington,  who 
prepared  a  map  of  the  township,  on  the  scale  of  one  hundred  and  six  rods 
to  the  inch,  showing  the  several  formations,  as  well  as  the  courses  of  the 
metallic  veins  and  the  location  of  mineral  deposits.  A  copy  of  this  was 
sent  to  Mr.  Sumner,  with  an  explanation  of  the  significance  of  the 
several  colors.  The  facts  ascertained  are  all  embodied  in  our  general 
geological  map. 

THE  NEW  MAP  OF  THE  SECOND  YEAR. 

The  map  of  the  state  spoken  of  above  showed  several  geological  fea 
tures,  under  the  following  headings:  i.  White  Mountain,  or  gneissic 
series.  2.  Sienite  group  of  Exeter  and  Dover.  3.  Porphyritic  gran 
ite.  4.  Common  granite.  5.  Merrimack  group.  6.  Quebec  group. 
7.  Coos  group.  8.  Calciferous  mica  schist.  9.  Clay  slates.  The  re 
marks  made  about  them  are  here  reproduced,  in  substance: 

i.  ll'hite  Mountain  or  Gneissic  Scries.  In  our  report  of  last  year  this  term  was  used 
to  indicate  the  general  mass  of  gneissic  and  granitic  rocks  of  the  state,  including  desig 
nations  three  and  four  of  the  present  map.  It  occupies  four  fifths  of  the  area  of  the 
state  ;  and  it  will  be  a  leading  object  of  our  survey  to  discover  the  relations  of  the  sev 
eral  members  of  the  group  to  one  another.  It  may  not  be  amiss  to  state  that  the  clue 
to  the  structure  of  the  whole  has  probably  been  discovered,  and  that,  by  diligence  and 
discrimination,  it  can  be  completely  followed  out.  The  practical  advantages  of  this 
knowledge  can  hardly  be  overrated,  since  information  will  at  once  be  afforded  restrict 
ing  the  occurrence  of  valuable  minerals  to  narrow  areas,  where  the  proper  research  will 
develop  them.  I  refer  to  such  minerals  as  the  soapstone  of  Francestown,  the  pyrites 
of  Sullivan  county,  the  mica  of  Grafton,  granites,  limestone,  feldspar,  tin,  lead,  etc. 

I  am  satisfied  that  the  following  are  some  of  the  subdivisions  of  this  group,  which 
further  explorations  will  enable  us  to  define  with  precision  :  i,  normal  gneiss  ;  2,  fer 
ruginous  gneiss;  3,  granitic  gneiss;  4,  feldspathic  mica  schist;  5,  andalusite  gneiss; 


HISTORY    OF    GEOLOGICAL    SURVEY.  2/ 

6,  chiastolite  slates;  7,  granite;  8,  sienite  ;  9,  porphyritic  granite;  10,  quartzites ;  n, 
limestones  ;  12,  soapstones.  Little  doubt  remains  as  to  the  Eozoic  or  pre-Silurian  age 
of  this  entire  series. 

2.  Sienite  of  Exeter  and  Dover.     There  appear  to  be  sienitic  rocks  of  probable  Lau- 
rentian  age,  equivalent  to  the  Quincy  sienitic  group  of  Massachusetts,  prominently 
exposed   along   the   Boston  &  Maine   Railroad,  between  Massachusetts  and  Maine, 
especially  in  the  towns  of  Exeter  and  Dover.     They  form,  apparently,  an  anticlinal 
mass,  overlaid  by  the  Merrimack  slates. 

3.  Porphyritic  Granite.     Common  granite  full  of  large  crystals  of  feldspar,  generally 
from  one  half  of  one  to  two  inches  long,  which  give  a  checked  appearance  to  the  ledges. 
Some  portions  of  it  have  evidently  been  injected ;  while  the  arrangement  of  the  feld- 
spathic  crystals,  in  parallel  lines,  leads  to  the  suspicion  of  stratification  in  other  cases. 
The  area  is  probably  very  irregular. 

4.  Common  Granite.     The  granite  of  New  Hampshire  seems  to  have  originated  at 
five  different  periods.      First  are  the  (a)  indigenous  and  (b)  eruptive  granites  of  the 
White  Mountain  series ;  second,  the  (c)  indigenous  granites  of  the  Merrimack  group, 
in  which  none  of  the  eruptive  class  have  yet  been  seen ;  third,  the  (d)  indigenous  and 
(f)  eruptive  granites  of  the  Coos  and  calciferous  mica  schist  groups. 

5.  Merrimack  Group.     This  name  was  informally  applied  by  my  father  to  the  mica 
schists,  slates,  and  quartzites  contained  in  the  valley  of  the  Merrimack  river,  in  Massa 
chusetts.     They  skirt  the  Exeter  sienites  in  New  Hampshire,  lying  in  troughs,  on  the 
flanks  of  an  anticlinal.     They  probably  belong  to  the  earliest  Silurian  series. 

6.  Quebec  Group.     Lower  Silurian,  according  to  Sir  William  E.  Logan,  and  largely 
developed  in  northern  Cob's  county,  the  Ammonoosuc  gold  field,  and  along  the  Connec 
ticut  river,  chiefly  in  Vermont,  to  Bellows  Falls. 

7.  Coos  Group.     Under  this  appellation,  for  want  of  a  better  name,  are  included  the 
argillaceous  schists,  whetstone  mica  schists,  grits,  etc.,  of  northern  Cobs  county,  as 
explored  by  Mr.  Huntington,  the  similar  and  associated  rocks  in  Barford,  Hereford, 
Auckland,  etc.,  province  of  Quebec,  and  Essex  county,  Vermont,  the  quartzites,  stau- 
rolite  rocks,  micaceous  schists,  hornblende  schists,  perhaps  gneiss,  protogine,  and  other 
rocks  west  of  the  White  Mountain  series  and  east  of  the  Connecticut  river,  along  the 
whole  of  western  New  Hampshire,  but  excluding  the  calciferous  mica  schist  (8) .     The 
unity  of   the   series,    its   age,    thickness,    and   relations   to    the    Quebec  group,    (8) 
remain  to  be  defined.     It  appears  clearly  to  overlie  the  White  Mountain  series  uncon- 
formably.     The  calciferous  mica  schist  and  the  clay  slate  groups  seem  to  be  limited 
outliers.

CHAPTER    III. 


HISTORY  OF  THE  SURVEY — continued. 


y 

E  now  reach  an  epoch  in  the  history  of  our  explorations  when  it 
may  be  more  profitable  to  treat  of  the  subjects  of  research  each 
by  itself,  than  to  speak  of  the  yearly  progress  in  each.  The  time  had 
arrived  when  we  began  to  understand  the  structure  of  the  White  Moun 
tains,  which  knowledge  proved  to  be  the  key  to  that  of  the  rest  of  the 
state.  The  field  had  been  assigned  to  Mr.  Vose  originally ;  but  his  resig 
nation  left  the  place  vacant,  and  it  became  the  duty  of  the  state  geologist 
to  explore  the  territory  in  person.  The  special  plan  pursued  in  1870 
may  be  thus  described. 

This  laborious  field  of  research  includes  particularly  the  region  about 
thirty  miles  long  and  twelve  or  fifteen  wide,  bounded  by  Israel's,  Moose, 
Peabody,  Ellis,  and  Saco  rivers.  This  area  is  nearly  an  unbroken  forest, 
traversed  only  by  the  bridle-paths  and  roads  required  for  the  ascent  of 
Mt.  Washington  by  summer  visitors.  The  plan  pursued  was,  to  visit  sys 
tematically  every  one  of  the  numerous  peaks  and  valleys  composing  this 
area  with  the  hammer  and  barometer.  As  the  first  result  of  our  labors 
in  the  district  specified,  a  physical  model  of  the  mountainous  region  was 
constructed,  about  five  feet  in  length,  on  the  scale  of  one  hundred  and 
forty  rods  to  the  inch  horizontally,  and  one  thousand  feet  to  three  fourths 
of  an  inch  vertically.  Contour  lines  were  drawn  for  each  five  hundred 
feet,  and  were  made  the  basis  for  fashioning  the  mountains.  With  our 


3O  PHYSICAL    GEOGRAPHY. 

limited  resources,  much  reliance  was  placed  upon  estimates  of  the  loca 
tion  of  the  contour  lines,  without  actual  measurement.  Hence  this  model 
is  only  an  approximation  to  a  correct  representation,  but  is  sufficiently 
accurate  to  enable  all  interested  in  the  study  of  the  mountains  to  compre 
hend  the  relative  altitudes  and  courses  of  the  ranges,  especially  as  they 
stand  related  to  the  distribution  of  the  formations. 

After  the  exhibition  of  this  model  in  public,  information  was  furnished 
that  a  model  of  the  White  Mountains  had  been  fashioned  in  plaster,  sev 
eral  years  since,  by  Rev.  Dr.  Thomas  Hill,  lately  president  of  Harvard 
college.  This  was  upon  a  much  smaller  scale,  about  eighteen  inches 
square,  and  was  built  up  upon  the  basis  of  Bond's  Map  of  the  White 
Mountains,  published  in  1853.  It  includes  the  Franconia  region,  and  all 
the  mountains  as  far  south  as  Waterville  and  Conway.  An  inspection 
of  this  representation  shows  great  familiarity  with  the  structure  of  the 
mountains,  and  it  is  a  matter  of  regret  that  its  existence  has  been  known 
to  so  few  persons.  A  copy  of  it  has  been  presented  to  us  by  the  author, 
and  is  placed  in  the  state  museum  at  Hanover. 

So  numerous  were  the  localities  requiring  visitation,  that  six  of  the 
members  of  the  class  of  1871  of  Dartmouth  college,  C.  S.  D.,  were  in 
vited  to  assist  in  the  work  of  exploration.  These  were  B.  W.  Andrews, 
W.  B.  Douglass,  C.  J.  Johnson,  J.  F.  Pratt,  E.  Thompson,  and  Frank 
Woodbridge.  Aid  was  also  furnished  by  J.  H.  Huntington,  Dr.  Nathan 
Barrows,  and  E.  Hitchcock,  Jr.  We  procured  the  necessary  provisions 
and  other  supplies,  and  lived  among  the  mountains,  in  extempore  camps, 
till  the  various  points  had  been  explored  and  the  required  observations 
made.  Without  so  many  assistants,  the  early  completion  of  the  model 
would  have  been  impossible ;  and  all  who  take  pleasure  in  contemplating 
the  results  are  under  obligations  to  these  gentlemen  for  their  very 
arduous  labors. 

That  it  is  very  difficult  to  climb  high  mountains  is  a  statement  which 
no  one  will  deny.  Most  persons  who  visit  our  New  Hampshire  mountains 
are  well  satisfied  with  their  labors  when  a  single  peak  has  been  ascended 
on  foot.  They  are  willing  to  accept  almost  any  theory  that  may  be  pro 
posed  to  explain  their  geological  structure,  because  immense  labor  would 
be  required  to  disprove  it.  The  task  before  us  was  the  dissipation  of 
all  false  notions,  and  the  discovery  of  the  real  stratigraphical  structure 


HISTORY    OF    GEOLOGICAL    SURVEY.  31 

of  the  rocky  masses,  by  careful  induction.  The  whole  party  were  ani 
mated  with  the  desire  to  accomplish  this  object,  and  therefore  visited 
the  almost  inaccessible  peaks  and  ravines,  one  after  another,  till  all  had 
been  explored.  The  actual  exertion  often  put  forth  for  procuring  a  single 
specimen  was  greater  than  to  pass  over  Mt.  Washington  on  foot,  by  the 
paths.  Its  location  may  have  been  three  or  four  thousand  feet  above  the 
camp,  and  the  country  to  be  travelled  was  the  original  forest,  never  before 
traversed  except  by  hunters,  full  of  underbrush,  fallen  trees,  and  at  the 
higher  elevations  consisting  of  the  stiff  dwarf  spruces,  through  which  trav 
elling  is  almost  impossible.  After  overcoming  the  difficulties  of  threading 
the  forest  and  ascending  the  precipices,  the  rarified  air  of  the  upper  re 
gions  has  made  even  slight  exertions  burdensome.  We  take  great  pleas 
ure,  therefore,  in  pointing  to  the  results  of  our  labors,  as  they  have  been 
acquired  only  through  infinite  toil ;  and  we  feel  sure  that  if  our  generali 
zations  are  not  accepted,  it  will  be  a  long  time  before  any  other  party  will 
labor  so  hard  as  we  have  done  to  disprove  our  theories. 

A  sketch  of  the  various  opinions  that  have  been  entertained  respecting 
the  age  and  structure  of  the  White  Mountains  was  presented  at  some 
length  in  the  report  for  1870;  also,  further  definitions  respecting  the  Coos 
group,  and  the  manner  in  which  the  valley  of  the  White  Mountain  notch 
had  been  excavated.  The  conclusions  expressed  concerning  the  strati- 
graphical  structure  have  not  been  modified  by  subsequent  explorations. 
The  following  opinion  is  expressed  as  to  the  age  of  the  series : 

In  fine,  the  White  Mountain  rocks  are  believed  to  belong  to  two  great 
systems,  the  Gneissic  and  the  Coos  group.  The  first  are,  for  convenience, 
called  the  White  Mountain  series ;  and  in  the  area  of  the  model  are  vari 
ous  imperfect  gneisses,  verging  into  mica  schists,  a  few  beds  of  genuine 
gneiss,  granitic  gneiss,  andalusite  gneiss  and  granite,  both  bedded  and  in 
Veins.  These  rocks  appear  to  underlie  the  Coos  group,  and  are  therefore 
older.  The  presumption  is  that  they  are  entirely  Eozoic,  though  it  is  not 
clear  whether  they  are  to  be  considered  as  the  equivalent  of  the  Lauren- 
tian  of  Canada,  or  more  nearly  the  age  of  the  Cambrian  of  Great  Britain, 
as  restricted  by  the  government  survey. 

This  White  Mountain  series  has  a  great  development  in  the  middle  and 
southern  parts  of  the  state,  perhaps  embracing  everything  not  included  in 
the  Exeter,  Merrimack,  and  Cods  groups.  Its  satisfactory  reference  to 


32  PHYSICAL    GEOGRAPHY. 

the  Eozoic  series  will  enable  us  to  clear  up  the  obscurities  of  New  Hamp 
shire  geology,  and  make  the  study  of  our  strata  as  interesting  as  that  of 
the  well-established  fossiliferous  groups  in  other  parts  of  the  country. 

WHITE  MOUNTAIN  EXPLORATIONS  IN  1871. 

The  most  valuable  of  all  our  reports  is  that  which  details  the  operations 
for  1871.  The  conclusions  stated  had  been  foreshadowed  by  the  results 
of  the  previous  years'  explorations,  but  were  rendered  much  more  satis 
factory  by  our  labors  in  the  area  lying  between  the  Saco  and  Pemige- 
wasset  rivers,  and  north  of  Sandwich. 

On  the  seventeenth  of  June,  with  the  assistance  of  eleven  gentlemen 
from  the  graduating  class  at  Dartmouth  college,  the  exploration  of  the 
Pemigewasset  country  was  commenced,  and  continued  uninterruptedly 
for  a  month.  These  gentlemen  kindly  proffered  their  services  without 
charge,  and  deserve  the  thanks  of  the  community  for  their  exertions  in 
our  behalf.  Some  have  imagined  the  party  as  enjoying  the  luxuries  of 
the  season  in  the  cushioned  seats  of  the  well  appointed  hotels  about  the 
mountains,  with  every  want  eagerly  anticipated  by  dutiful  attendants.  On 
the  contrary,  our  houses  were  hastily  extemporized  sheds  ;  our  beds,  a  few 
boughs  or  ferns  placed  upon  boards ;  our  food  consisted  of  stale  crackers 
and  preserved  meats,  save  a  rare  taste  of  trout  and  berries  gathered  in 
climbing  mountains,  and  the  luxury  of  an  occasional  basket  of  provisions 
sent  by  kind  friends  at  the  Profile  house ;  and  we  were  our  own  servants. 
The  party  consisted  of  A.  A.  Abbott,  M.  O.  Adams,  A.  M.  Bachelor,  R. 
M.  Carleton,  C.  H.  Conant,  G.  E.  Davis,  H.  C.  Harrison,  C.  W.  Hoitt, 
Jonathan  Smith,  W.  Upham,  A.  W.  Waters.  All  these  gentlemen  con 
tributed  something  towards  the  accumulation  of  facts  bearing  upon  the 
important  questions  discussed  in  the  first  part  of  the  report.  Messrs. 
Conant  and  Smith  were  so  fortunate  as  to  discover  a  new  lake  on  the 
north-west  side  of  Haystack  mountain,  which  we  christened  Haystack 
lake.  It  is  parallelogramic  in  shape,  fifteen  rods  long  and  half  as  wide, 
with  rather  shallow  water,  forming  the  head  waters  of  Gale  river,  three 
thousand  seven  hundred  and  eighty-seven  feet  above  tide-water,  as  deter 
mined  by  the  aneroid  barometer.  Messrs.  Abbott  and  Bacheler  suc 
ceeded  in  discovering  a  second  lake,  still  larger,  upon  the  east  side  of 
Mt.  Kinsman,  named,  as  the  other,  after  the  mountain.  Others  of  the 


HISTORY    OF    GEOLOGICAL    SURVEY.  33 

party  measured  the  length  of  the  profile  of  the  "Old  Man  of  the  Moun 
tains,"  finding  it  to  be  thirty-six  feet  from  chin  to  top  of  the  head, — the 
face  itself  being  twelve  hundred  feet  above  the  lake  beneath.  Soon  after 
the  disbanding  of  the  first,  a  new  party  was  formed,  consisting  of  A.  A. 
Abbott,  W.  Flint,  and  W.  Upham,  with  the  aid  of  E.  C.  Atwood  for  a 
short  period.  This  second  party  remained,  some  of  them,  two  months 
longer,  exploring  the  country  as  far  south  as  Sandwich. 

DESCRIPTION  OF  THE  MAP. 

With  the  report  there  appeared  a  geological  map  embodying  the  results  of  all  our  ex 
plorations.  The  colors  upon  the  map  indicated  the  geographical  relations  of  ten  groups. 
In  the  absence  of  precise  knowledge,  spaces  were  left  uncolored  in  certain  districts. 
The  topographical  basis  is  the  map  of  C.  H.  V.  Cavis,  prepared  for  Eastman's  White 
Mountain  Guide,  upon  the  scale  of  five  miles  to  the  inch,  it  being  the  most  convenient 
one  accessible  to  us.  On  account  of  the  difficulties  in  the  way  of  exploring  among  the 
mountains,  which  have  already  been  described,  this  delineation  can  only  be  regarded 
as  a  reconnoissance,  especially  as  the  true  position  of  the  rocks  did  not  suggest  itself 
till  late  in  the  spring  of  1872,  when  the  field  notes  were  being  compared  with  specimens. 
The  areas  will  be  briefly  mentioned,  and  the  most  important  conclusions  dwelt  upon 
at  length. 

1.  Porphyritic  Gneiss.     This  is  an  ordinary  gneiss,  carrying  numerous   crystals  of 
orthoclase  or  potash-feldspar,  from  a  quarter  of  one  to  two  inches  long.     The  longer 
axes  may  be  parallel  to  the  strike,  or  arranged  helter-skelter.     It  passes  into  granite 
with  the  same  porphyritic  peculiarity  of  structure.     Its  most  northern  area  lies  along 
the  Ammonoosuc  river  in  Bethlehem,  Littleton,  and  Whitefield.     Next,  commencing 
west  of  Haystack  mountain,  at  some  unknown  point,  is  another  range,  which  passes 
southerly  on  the  west  flank  of  Profile  mountain,  and  makes  up  the  great  mass  of  Kins 
man  or  Blue  mountain;    thence  passes  southerly  to  Woodstock    and  Campton.     It 
crops  out  on  the  west  side  of  Moosilauke — how  extensively  has  never  been  determined. 
A  spur  from  this  appears  at  the  Lake  of  the  Clouds  on  Mt.  Lafayette,  and  passes 
southerly  towards  the  Basin.     It  may  occupy  part  of  the  uncolored  area  west  of  the 
Lafayette  range.     Upon  the  other  side  of  the  Pemigewasset  country,  this  formation 
shows  itself  in  the  valley  of  Sawyer's  river,  on  the  south  side  of  Mt.  Carrigain.     It  is 
there  covered  by  compact  feldspar.     It  reappears  in  Waterville,  on  Cascade  brook, 
Snow's  mountain,  Bald  Knob,  and  upon  other  high  mountains  in  Sandwich,  whence  it 
passes  out  of  the  limits  of  the  map.     We  suppose  this  to  be  the  oldest  formation 
among  the  mountains.     Geologists  speak  of  a  rock  of  this  character  as  common  in  the 
Laurentian,  in  various  parts  of  North  America  and  Europe. 

2.  Bethlehem  Gneiss,     The  whole  of  Bethlehem  is  underlaid  by  a  gneiss  abounding 
in  a  talcoid  mineral,  perhaps  pinite.     The  orthocla'se  is  abundant,  usually  pink  or  flesh

PHYSICAL    GEOGRAPHY. 


colored,  and  mica  is  sparsely  disseminated  through  the  rock.  It  is  usually  granitic,  so 
much  so  that  it  has  always  been  called  granite  heretofore.  Its  most  remarkable  feature 
consists  in  the  common  cast  and  west  strike  between  Littleton  and  Cherry  mountain. 
In  Whitefield,  Mr.  Huntington  finds  the  rock  tending  more  north-easterly.  Lying  be 
tween  outcrops  of  porphyritic  gneiss,  the  natural  inference  is  that  it  is  a  synclinal,  and 
therefore  newer,  while  the  strike  indicates  a  very  great  antiquity,  judging  from  the  same 
phenomenon  elsewhere.  The  dip  is  monoclinal,  averaging  75°  northerly,  across  Beth 
lehem,  but  anticlinal  in  Whitefield.  If  the  anticlinal  structure  is  persistent,  evidence 
may  be  afforded  that  this  peculiar  gneiss  is  older  than  No.  i.  There  is  a  limited  out 
lier  of  this  rock  west  of  Haystack  mountain,  another  north-west  of  Alt.  Pemigewasset, 
a  third  about  Big  Coolidge  mountain  in  Franconia,  and  perhaps  another  south  of  the 
east  branch  of  the  Pemigewasset.  These  limited  outliers  give  the  idea  of  a  rock 
newer  than  No.  I.  The  boulders  scattered  to  the  north  of  Lafayette,  in  Franconia 
and  Bethlehem,  which  Professor  Agassiz  regards  as  moraines  of  a  local  glacier  push 
ing  northerly,  are  composed  of  this  rock. 

3.  Gneiss.     The  gneiss  west  of  No.  I,  in  Franconia  and  Lanclaff,  and  also  to  a  limited 
extent  east  of  the  Labrador  felsite  on  Tripyramid,  is  a  common  variety,  and  has  not 
yet  been  referred  to  any  of  the  sub-divisions  recognized  elsewhere. 

4.  White  Mountain  or  Andalusite  Gneiss.     This  is  the  variety  described  in  previous 
reports  as  containing  andalusite  or  staurolite.     It  occupies  the  great  part  of  the  White 
Mountain  area  east  of  the  Saco,  making  up  the  bulk  of  the  highest  peaks.     It  reap 
pears  on  equally  extended  a  scale  south  of  Mts.  Pequawket,  Chocorua,  and  Whiteface. 
About  Dr.  Bemis's  residence,  or  the  "Mt.  Crawford  house"  of  the  map,  this  rock 
seems  to  be  isolated,  being  surrounded  by  granite.     A  little  of  it  lies  to  the  north  of 
the  Labrador  in  Albany,  and  is  not  represented  upon  the  map.     Farther  north  it  crops 
out  in  Whitefield,  and  there  is  a  range  apparently  from  the  west  flank  of  Profile  moun 
tain  to  Moosilauke.     More  is  found  in  Thornton,  and  there  is  an  extensive  area  of  it 
to  the  south-west,  which  is  not  designated  upon  the  map.     The  presumption  is  that  the 
beryl-bearing  gneiss  east  of  the  Pemigewasset,  on  the  edge  of  Woodstock  and  Thorn 
ton,  is  the  same  rock  which  extends  into  Campton.     The  amount  of  andalusite  in  this 
area  is  very  small.     The  relative   position  of  the   andalusite   gneiss  remains  to  be 
determined.     It  seems   to  be   newer  than  Nos.    I    and    2,  but  its   relations   to   the 
granites  and  felsites  are  yet  to  be  made  out. 

5.  Common  Granite.     The  type  of  this  rock  appears  at  the  Basin,  Pool,  and  Flume 
in  Franconia,  and  at  Goodrich's  falls  in  Jackson.     The  constituents  are  rather  coarse, 
never  more  than  an  inch,  and  usually  one  fourth  of  an  inch  long.     The  orthoclase  is 
commonly  flesh-colored,  and  is  the  most  abundant  ingredient.     The  quartz  is  smoky, 
translucent,  and  oftqn  roughly  crystallized.     The  mica  is  the  least  abundant  of  the 
three  constituents,  and  is  black.     The  joints  passing  through  this  rock  are  both  hori 
zontal  and  vertical.     This  rock  seems  to  form  the  basis  of  the  whole  Pemigewasset 
country,  and  the  areas  left  blank  will  most  likely  be  found  to  consist  of  this  same  ma 
terial.    The  first  area  is  that  in  Franconia,  embracing  the  Profile  and  Cannon  moun- 


HISTORY    OF    GEOLOGICAL    SURVEY.  3$ 

tains,  besides  the  parts  already  specified.  The  mountains  show  a  finer  grained  rock 
than  the  valleys.  Some  of  it  seems  to  extend  into  the  uncolored  area  between  No.  I 
and  the  Lafayette  range.  This  probably  connects  under  Flume  mountain  with  the 
granites  on  the  East  Branch  in  Lincoln  and  Thornton.  More  appears  near  the  forks 
of  the  East  Branch,  Hancock  mountain,  and  the  ridge  north,  including  the  falls  in 
the  valley  of  Mad  river  in  Waterville,  abundantly  in  the  Swift  River  valley  in  Albany, 
and  about  Conway,  passing  under  Pequawket,  and  extending  into  the  Green  Hills.  The 
small  area  of  Bald  Face  and  Mt.  Eastman  in  Chatham  has  a  fine  grain,  and  possibly 
is  of  a  different  age. 

The  largest  area  of  this  rock  upon  the  map  extends  from  Jackson  to  Carroll.  The 
Saco  valley  above  Rocky  Branch  is  mostly  excavated  out  of  it.  The  excavation  of  the 
White  Mountain  notch  out  of  this  granite  was  alluded  to  last  year.  The  high  range  north 
from  Mt.  Lowell  to  Mt.  Willard  is  probably  of  this  rock.  East  of  the  Saco  the  andalu- 
site  gneiss  seems  to  have  been  cut  by  it,  Mts.  Crawford  and  Resolution  being  composed 
of  granite.  Mt.  Deception,  and  the  country  east  of  the  old  Fabyan  house,  are  made  up 
of  a  different  sort  of  a  granite,  whitish  or  grayish  in  color,  with  the  feldspar  in  narrow 
crystals,  porphyritic  in  appearance.  But  the  range  from  the  north  end  of  Mt.  Tom  to 
the  lower  falls  on  the  Ammonoosuc,  and  the  three  "Sugar  Loaves"  farther  west,  are 
entirely  of  the  typical  variety  of  coarse  granite. 

6.  Trachytic  Granite.     Above  No.  5,  with  the  same   horizontal   appearance,   is   a 
granite  of  trachytic  or  serni-porphyritic  aspect.     The  feldspar  is  orthoclase,  as  shown 
by  analysis,  and  most  of  the  rock  is  made  of  it,  being  essentially  rounded  crystals 
imbedded  in  a  granitic  paste,  with  scarcely  any  quartz,  and  rarely  a  peppering  of  dark 
mica.    It  often  contains  a  small  per  cent,  of  manganese.    The  first  great  expanse  of  this 
rock  lies  between  the  saw-mill  of  Rounsevel  &  Coburn,  in  Carroll,  on  the  Ammonoosuc, 
and  Waterville.     The  Twin  Mountains,  Haystack,  a  portion  of  the  Lafayette  range 
beneath  the  cap,  Mts.  Liberty,  Osceola,  and  other  high  peaks,  are  mainly  composed  of 
this  trachytic  granite.     It  will  be  observed  that  this  area  is  wholly  in  the  forest  region, 
untraversed  by  roads ;  hence  it  is  not  strange  that  its  peculiar  characters  should  not 
have  been  recognized  earlier.     There  is  some  of  this  rock  north  of  Mt.  Carrigain,  and 
the  Sawyer's  Rock  range  appears  to  belong  here.     Other  localities  are  high  up  Rocky 
Branch  in  Bartlett,  Iron  mountain,  the  valley  of  the  Saco  in  Bartlett,  underlying  the 
great  mass  of  Pequawket,  but  above  the  common  granite.     The  rock  referred  to  this 
division,  along  the  Swift  river  and  the  Ossipee  mountains,  is  made  of  finer  materials, 
with  more  of  the  paste,  and  that  of  a  darker  color  than  the  ledges  farther  west.     It 
also  disintegrates  less  readily. 

7.  Brecciated  Granite.     This   designation  applies  to  the  rocks  forming  Eagle  cliff 
in  Franconia,  and  several  nameless  peaks  between  Profile  and  Kinsman.     The  frag 
ments  most  easily  recognized  are  those  of  porphyritic  gneiss,  dark  gneiss,  and  horn 
blende,   imbedded  in  a  very  compact  feldspathic  paste.     Along  Eagle  cliff  there  are 
appearances    of  stratification,  and   at  Echo  lake    the    brecciated   granite  appears  to 
underlie  the  porphyritic  gneiss.     The  rock  is  irregular  in  arrangement,  as  if  thrust

up  from  below.  As  it  contains  no  fragment  of  the  common  or  trachytic  granite, 
we  have  concluded  it  to  be  more  ancient  than  either  of  these  granites,  but  newer 
than  the  porphyritic  gneiss.  The  two  areas  are  also  probably  connected  beneath  the 
Pemigewasset  valley,  under  the  common  coarse  granite,  which  cither  flowed  in  above 
the  breccia,  or  was  deposited  upon  it  quietly  in  some  other  way. 

8.  Norian.     This  includes  several    areas    of  labradorite   rock,   including   compact 
felsites,  breccias,  and  sienites.     They  are  the  Lafayette  range,  Twin  Mountain  area,  near 
Loon  pond,  Trypyramid  region,   Carrigain  district,  north  of  Mt.  Tom,  valley  of  Dry 
river,  valley  of  Rocky  Branch,  Sable  mountain  in  Jackson,  Mt.  Pequawket  or  Kiarsarge, 
Deer  River  valley  in  Albany,  near  Mt.  Chocorua,  and  Red  Hill,  Moultonboro'.     There 
are  other  areas  to  be  referred  to  the  same  group  outside  of  the  White  Mountain  area. 

9.  Clay  slate  and  Quart  sites.     The  first   of   these  areas  is  a  limited  one  on  the 
south  slope  of  Pequawket ;  the  second  south-west  of  Mt.  Willard,  passing  into  andalu- 
site  slates  and  quartzites  on  Mts.  Willey,  Field,  and  Tom. 

10.  Coos  Group.     This  embraces  the  andalusite  slates  on  the  east  flank  of  the  Mt. 
Washington  range,  repeated  on  the  north-east  side  of  Pine  mountain,  near  Gorham, 
and  the  staurolite   rocks  from   Littleton  southwards,   curving  around  the  underlying 
Bethlehem  gneiss.     Only  the  eastern  border  of  the  latter  is  indicated  upon  the  map. 

WHITE  MOUNTAIN  EXPLORATIONS  IN  1872  AND  1873. 

A  still  larger  party  was  organized  for  work  in  1872.  Under  the  direc 
tion  of  J.  A.  Leach,  of  Nashua,  a  plane-table  survey  was  made  of  the 
south-west  portion  of  the  mountain  area,  with  the  design  of  perfecting 
the  map.  The  rest  of  the  party  examined  the  rocks  along  the  Saco  val 
ley  and  in  Albany  for  a  period  of  three  weeks,  under  the  guidance  of  Mr. 
Huntington.  The  explorations  served  to  confirm  the  theory  of  the  pre 
vious  year  concerning  the  arrangement  of  the  formations.  The  parties 
consisted  of  the  following  members  of  the  class  of  1872,  Dartmouth  col 
lege:  E.  J.  Bartlett,  W.  H.  Cotton,  L.  G.  Farmer,  G.  H.  Fletcher,  A.  M. 
French,  G.  M.  French,  W.  H.  Galbraith,  W.  A.  Holman,  E.  D.  Mason,  C.

Ladd  and  A.  O.  Lawrence  of  the  class  of  1873. 

In  1873  a  few  points  about  the  mountains  were  visited  by  Mr.  Hunt 
ington  and  myself  for  the  sake  of  completing  our  knowledge  of  them. 
The  exploration,  so  far  as  it  seemed  advisable  to  proceed  with  our  present 
instructions  from  the  state  authorities,  had  been  essentially  completed 
in  1872. 


HISTORY  OF  GEOLOGICAL.  SURVEY.  37 

THE  LABRADOR  SYSTEM. 

The  group  of  rocks  referred  by  us  to  the  Labrador  system  are  first 
described  in  the  1871  report,  and  certain  passages  in  the  history  of  its 
exploration  may  be  of  considerable  importance.  The  names  of  "Norian 
system  "  and  "  Norite  rocks  "  were  applied  to  this  group  in  the  report  after 
a  suggestion  by  Dr.  Hunt.  Upon  reflection  it  seems  more  proper  to  use 
the  first  name  suggested  for  the  system,  rather  than  the  lithological 
appellation  for  a  characteristic  member. 

The  first  locality  described  is  in  Waterville.  Its  discovery  was  due  to 
the  uncovering  of  the  ledges  by  the  remarkable  rain-storm  ending  Oct.  4, 
1869.  The  ravages  of  the  freshet  were  described  by  Prof.  G.  H.  Perkins, 
PII.  D.,  of  Burlington,  Vt,  who  speaks  of  the  ledge  as  a  "  black  hornblendic 
rock."  In  May,  1870,  Mr.  Huntington  went  up  the  same  stream  and 
brought  back  specimens  of  the  dark  rock,  which  he  thought  might  be 
labradorite.  He  carried  a  fragment  of  it  to  Dr.  T.  Sterry  Hunt,  of 
Montreal,  for  examination,  March  21,  1871.  Dr.  Hunt  wrote  as  follows 
concerning  this  rock  to  Mr.  Huntington : 

"The  blue  granular  crystalline  rock  from  Waterville,  N.  H.,  consists  chiefly  of  a 
feldspar  allied  to  labradorite.  I  have  not  separated  the  grains  to  get  them  quite  pure, 
but  the  mass  is  seen  under  a  glass  to  consist  of  the  bluish-grey  cleavable  feldspar,  with 
some  mica,  probably  biotite,  and  a  little  magnetic  iron  ore.  From  a  pulverized  sample 
the  magnet  takes  up  about  5  per  cent,  of  magnetic  grains ;  these  contain  a  little  titan 
ium.  The  analysis  of  the  material  thus  freed  from  the  magnetic  portion  gave  me, — 
silica,  50.30;  alumina,  25.10;  protoxide  of  iron,  4.23;  lime,  14.07;  magnesia,  2.95; 
volatile,  0.70  :  loss  (alkalies),  2.65=100.00.  I  have  found  the  feldspar  of  the  so-called 
labradorite  or  norite  rocks  very  variable  in  composition,  being  sometimes  more  and 
other  times  less  basic  than  typical  labradorite."  "The  analysis  agrees  closely  with 
what  might  be  expected  from  an  admixture  of  labradorite  with  biotite.  It  (the  rock) 
may  hold  a  little  hornblende,  but  I  did  not  discern  any.  Thus  the  rock  agrees  chemi 
cally  and  mineralogically  with  much  of  the  norite  of  the  labradorite  series  of  rocks,  in 
which  titaniferous  iron  ore  and  biotite  not  unfrequently  occur." 

About  the  same  time  the  following  passage  was  written  by  Dr.  Hunt  in 
a  letter  to  the  state  geologist.  By  oversight,  the  second  passage  was 
printed  in  a  communication  to  the  American  Journal  of  Science,  January, 
1872,  instead  of  the  first.  The  error  was  corrected  in  the  report  for  1871. 


og  PHYSICAL    GEOGRAPHY. 

"  The  specimen  brought  by  Mr.  Huntington  is  a  labracloritc  or  norite  rock,  which 
resembles  in  composition  and  aspect  that  of  the  Labradorian,  with  this  difference,  how 
ever,  that  it  is  much  more  tender  and  friable,— and,  in  this  respect,  resembles  the  gran 
itic  gneiss  of  the  White  Mountains,  as  compared  with  similar  rocks  in  the  Adirondacks." 

I  first  visited  the  locality  August  18  and  19,  1871,  and  subsequently  on 
September  20,  in  company  with  Prof.  J.  D.  Dana,  LL.D.,  of  New  Haven, 
Conn.  The  conclusions  derived  from  these  two  visits  appeared  in  a  short 
article  by  myself  in  the  journal  above  cited,  followed  by  descriptive 
analyses  of  some  of  the  rocks  by  Mr.  E.  S.  Dana,  of  New  Haven,  Conn. 
The  description  of  the  rocks  agrees  with  that  which  appeared  subse 
quently  in  the  1871  report,  save  in  one  or  two  particulars,  which  I  will 
mention. 

In  ascending  from  "Beckytovvn,"  the  first  rock  seen  was  called  gneiss, 
with  nodular  orthoclasc,  with  its  supposed  strata  dipping  by  compass  80° 
S.  70°  W.  This  rock  is  evidently  the  same  with  the  "trachytic  granite" 
of  Mt.  Osceola  and  elsewhere.  After  noticing  its  distribution  in  mass 
throughout  so  large  a  portion  of  the  mountains,  and  its  nearly  horizontal 
position  between  the  coarse  granite  below  and  the  felsites  above,  the  pre 
sumption  arises  that  these  so-called  strata  may  be  bands  of  mica  whose 
planes  do  not  correspond  with  those  of  accumulation,  but  have  been 
superinduced  during  the  metamorphism  of  the  rock.  The  jointed  planes, 
dipping  about  25°  westerly,  would  be  those  of  stratification,  if  the  rock  is 
stratified.  These  were  pointed  out  by  J.  P.  Lesley.* 

A  few  rods  up  Norway  brook  appears  the  first  ledge  of  the  ossipyte. 
Its  junction  with  the  gneiss  is  concealed  by  drift.  For  about  a  mile 
similar  ledges  occur,  some  exposures  being  sixty  or  seventy  feet  long. 
Considered  as  an  isolated  case,  it  is  difficult  to  determine  the  planes  of 
stratification,  since  two  prominent  sets  of  jointed  planes  exist,  either  of 
which  might  be  taken  for  strata.  One  set  dip  about  20°  northerly,  and 
are  the  most  numerous;  the  other  dip  about  75°  W.  10°  S.  As  the  lat 
ter  correspond  better  in  position  with  the  supposed  strata  of  nodular 
gneiss,  it  was  thought  they  indicated  the  proper  lines  of  deposition.  The 
former,  however,  are  what  appear  at  the  first  glance  to  be  the  strata ;  and, 
as  by  this  interpretation  the  position  of  the  rocks  at  Watcrville  will

HISTORY    OF    GEOLOGICAL    SURVEY.  39 

correspond  with  that  in  Franconia  about  the  Lafayette  range,  our  former 
ideas  must  be  modified.  We  should  have,  therefore,  an  underlying  gran 
ite,  as  seen  in  Mad  river  two  miles  below  Greely's  hotel ;  then  the  trachytic 
granite  of  Osceola,  extending  to  the  cascades  and  including  the  "nodular 
gneiss"  on  Norway  brook,  dipping  gently  westerly;  and  finally  above 
both,  the  ossipyte  schists,  with  a  small  inclination. 

Mr.  E.  S.  Dana  has  carefully  analyzed  specimens  of  the  Waterville 
rocks,  and  described  the  assemblage  as  a  new  rock,  with  the  name  of 
Ossipyte,  after  one  of  the  aboriginal  tribes  of  Indians  formerly  dwelling 
in  the  neighborhood. 

The  following  are  his  results  with  the  ossipyte,  it  being  composed  of 
the  two  minerals,  labradorite  and  chrysolite :

The  large  percentage  of  iron  (determined  volumetrically)  had  not  been  expected, 
as  the  eye  had  failed  to  detect  any  impurities  in  the  fragments  selected  for  analysis. 
Some  very  thin  pieces  were  afterwards  examined  under  the  microscope ;  and  by  this 
means  it  was  found  that  even  the  clearest  pieces  contained  very  minute  grains  of  an 
iron  ore,  from  gL-th  to  -j^th  of  an  inch  in  diameter,  which  were  strongly  attractable  by 
the  magnet.  Microscopic  dark  specks  less  than  jowo^1  °f  an  incn  m  S'IZQ  were  also 
observed,  and  at  first  referred  to  the  same  cause  ;  but,  on  magnifying  them  800  diame 
ters,  it  was  concluded  that  they  were  air-cavities  in  the  structure  of  the  feldspar,  and 
not  any  foreign  matter.  The  peculiar  dark  smoky  color  of  the  rock  is  doubtless  to  be 
explained  by  the  presence  of  these  particles  of  iron  ore. 

This  magnetic  iron  ore,  a  sufficient  amount  for  the  test  having  been  picked  out 
by  the  magnet,  gave  a  decided  reaction  for  titanic  acid.

The  oxygen  ratio  of  the  bases  and  silica  afforded  is  nearly  i  :r,  and  of  the  iron 
and  magnesia  about  i  :2  ;  whence  the  formula  (JFe-f  |Mg)aS.  This  is  then  a  chryso 
lite,  containing  an  unusually  large  per  centage  of  iron  (here  a  constituent  of  the  min 
eral,  and  not  owing  to  the  presence  of  impurities).  The  amount  of  iron  is  not  strange, 
considering  the  fact  that  the  rock  contains,  diffused  throughout  it,  so  much  free  iron  ore. 

This  chrysolite  has  the  same  ratio  deduced  for  hyalosiderite,  but  still  differs  widely 
in  fusibility  and  other  characters.  It  is,  in  fact,  a  true  chrysolite  in  all  respects,  while 
hyalosiderite  is  a  doubtful  compound,  probably  owing  its  fusibility  in  part  to  the  potash 
present.  B.  B.  the  chrysolite  is  nearly  infusible. 

The  following  is  Mr.  Dana's  analysis  of  another  specimen  of  labradorite : 

This  feldspar  has  a  grayish-white  color,  is  destitute  of  iridescence,  and  only  care 
ful  searching  reveals  any  striations.  Two  analyses  afforded, —

Both  analyses  show  that  the  labradorite  of  this  region  is  remarkable  for  the  large 
proportion  of  lime  present. 

The  next  point  in  the  history  of  these  rocks  in  New  Hampshire  relates 
to  a  discussion  respecting  the  discovery  of  the  mineral  aggregate  named 
"ossipyte."  In  a  letter  of  May  i,  1872  (which,  with  Prof.  Dana's,  is  pub 
lished  in  full  in  the  report  for  1871),  Dr.  Hunt  speaks  thus  concerning 
Mr.  E.  S.  Dana's  paper:  "He  remarks  that  a  rock  consisting  of  labra- 
dor  with  chrysolite  (olivine)  has  not  been  previously  described.  It  was, 
however,  long  since  noticed  by  Macculloch  in  Skye,  and  by  G.  Rose  at 
Elfdalen.  [Senft  die  Felsartcn ;  also,  Geology  of  Canada,  p.  650.]" 

The  substance  of  this  note  having  been  communicated  to  Mr.  Dana, 
the  following  letter  came  from  his  father : 

PROF.  C.  H.  HITCHCOCK. 

My  Dear  Sir— In  the  absence  of  my  son,  Mr.  Edward  S.  Dana,  now  on  his  way  to 
Europe,  I  write  a  brief  reply  to  your  letter  of  the  2gth  inst.  You  stated  that  Prof.  T. 
Sterry  Hunt,  in  a  recent  note,  objects  to  Mr.  Dana's  remark  that  a  rock  of  the  compo 
sition  of  the  ossipyte  of  Waterville  had  not  before  been  described,  and  that  he  refers 
to  Macculloch  as  having  observed  the  same  in  Skye,  and  G.  Rose  another  example  of 
it  at  Elfdalen  in  Sweden.  Mr.  Hunt  is  evidently  unaware  of  the  facts.  Macculloch 


HISTORY    OF    GEOLOGICAL    SURVEY.  41 

found  chrysolite  in  Skyc,  according  to  his  two  articles  in  Vols.III  and  IV  of  the  Trans 
actions  of  the  Geological  Society  of  London,  only  in  trap  or  "amygdaloid;"  and  he 
repeats  the  same  essentially  in  his  work  on  rocks,  the  chrysolite  being  spoken  of  as 
occurring  in  an  eruptive  or  overlying  rock.  Greg  and  Lettsom,  in  their  work  on  British 
Mineralogy  (1858),  confirm  this  by  speaking  of  the  chrysolite  of  Skye  as  being  found 
in  trap.  Moreover,  the  chrysolite  is  one  of  three  constituents. — the  other  two  being 
hornblende  or  augite,  and  a  feldspar ;  and  the  rock  is  not  Laurentian  or  Norian. 

The  rock  of  Elfdalen  is  undoubtedly  related  to  that  of  Waterville,  and  yet  is  widely 
different.  I  have  not  seen  Rose's  description  of  it.  But  Senft,  to  whom  Mr.  Hunt 
refers,  speaks  of  it  as  a  hypersthene  rock,  that  is,  a  granular  compound  of  labradorite 
and  hypersthene,  with  grains  of  chrysolite  as  an  accessory  ingredient.  The  ossipyte, 
on  the  contrary,  consists  almost  solely  of  labradorite  and  chrysolite,  there  being  "only 
a  very  little  of  a  black  mineral,  probably  hornblende."  I  examined  the  specimens  of 
ossipyte  with  Mr.  Dana, — the  same  that  I  collected  when  in  Waterville  with  you, — and 
through  much  of  it  could  detect  no  hornblende  whatever.  Mr.  Dana  was  right,  there 
fore,  in  saying  that  this  Waterville  rock,  consisting  essentially  of  labradorite  and 
chrysolite,  is  one  not  previously  described.  The  principal  constituent,  besides  the  two 
mentioned,  was  the  titaniferous  iron  ore,  which  he  found  distributed  in  microscopic 
grains  through  the  labradorite. 

The  light  colored  rock,  from  a  point  higher  up  the  stream,  determined  to  be  a 
labradorite  rock  by  Mr.  Dana,  is,  as  he  observes,  wholly  different  from  the  ossipyte,  it 
containing  much  hornblende  and  no  chrysolite  ;  and  the  titaniferous  iron  ore  in  visible 
grains,  instead  of  invisible  particles  disseminated  through  the  labradorite. 

After  the  publication  of  these  letters,  Dr.  Hunt  writes  to  the  effect  that 
he  had  personally  examined  Macculloch's  specimens  in  Europe,  and  felt 
confident  that  the  rock  of  Skye  was  the  same  with  that  from  Waterville. 
Per  contra,  Prof.  Dana  communicates  a  message  from  Prof.  Geikie,  direc 
tor  of  the  geological  survey  of  Scotland,  in  which  it  is  stated  that  the 
rock  of  Skye  is  an  eruptive  rock  related  to  trap.  Whatever  may  be  the 
truth  as  to  the  Scottish  rock,  it  is  clear  that  no  one  had  proposed  any 
technical  name  for  this  mineral  aggregate  before  Mr.  Dana;  and  there 
fore,  by  the  canons  of  lithological  nomenclature,  the  designation  of 
"ossipyte"  is  entitled  to  recognition  and  acceptance. 

The  1871  report  contains  a  full  description  of  this  locality  at  Water 
ville,  and  an  enumeration  of  the  other  localities  of  the  same  formation. 
These  are  Sabba  Day  and  Down's  brooks,  Waterville  ;  Loon  pond,  Wood 
stock;  Lafayette  range;  Mt.  Tom;  Mt.  Washington  river;  and  Sable 
mountain,  in  Jackson.  These  are  the  only  ones  in  which  the  mineral 
labradorite  had  been  found  in  the  area  of  the  map.

DISCOVERY  OF  THE  SUCCESSION  OF  MEMBERS  OF  THE  LABRADOR  SYSTEM. 

The  same  report  contains  the  announcement  of  the  discovery  of  the 
relations  to  one  another  of  the  several  members  of  the  Labrador  group, 
and  also  to  the  underlying  porphyritic  gneiss,  White  Mountain  series,  and 
brecciated  granite. 

From  a  peak  north  of  Mt.  Lafayette  in  Franconia  to  Flume  mountain, 
there  seems  to  be  a  nearly  continuous  band  of  dark,  compact  feldspar, 
about  five  miles  long,  and  never  more  than  two  hundred  to  three  hundred 
feet  thick.  It  closely  resembles  some  of  the  compact  labradorites.  The 
layers  are  horizontal,  or  nearly  so,  resting  upon  trachytic  granite  through 
out.  It  has  not  actually  been  traversed  from  the  south  end  of  the 
Lafayette  ridge  to  Flume  mountain,  but  the  topographical  features  of  the 
country  are  such  as  to  render  probable  its  continuance  by  a  curve  to 
connect  with  that  which  has  been  observed  upon  the  latter  summit. 
The  annexed  wood-cut  will  show  the  relative  position  and  thickness  of 
the  rocks  between  Mt.  Liberty  (C)  and  Mt.  Flume  (A),  two  thousand 
two  hundred  and  fifty  feet  above  the  bottom  of  the  valley.  There  is  the 
common  coarse  granite  at  the  base,  the  celebrated  Plume  of  Lincoln 
(Franconia),  lying  at  the  bottom  of  the  valley  (F  in  the  figure),  eighteen 
hundred  and  forty-nine  feet  above  the  ocean.  Above  the  Pemigewasset 
river  there  may  be  six  hundred  feet  thickness  of  this  rock,  considering  it 
to  lie  horizontally,  before  reaching  the  trachytic  variety.  This  in  turn 
may  be  one  thousand  feet  thick,  as  shown  at  band  C.  This  rock  caps 
Mt.  Liberty,  but  the  compact  feldspar  has  been  spared  by  the  denuding 
agencies  upon  Mt.  Flume.  As  seen  by  the  general  map,  the  edges 
of  this  dark  rock  everywhere  rest  upon  the  trachytic  granite.

MT.  PEQUAWKET. 

The  same  granite  which  appears  at  the  Flume,  is  found  in  the  Green 
Hills,  and  all  along  through  Conway,  at  Kiarsarge  village,  and  in  the  lower 
part  of  the  mountain  itself.  Above  this  the  trachytic  granite  occurs  upon 
all  sides  most  distinctly  (the  fourth  had  not  then  been  explored).  It  is  not 
abundant  on  the  south  and  east,  but  very  characteristic.  On  the  south, 
it  crops  out  on  the  hillside  below  the  slate.  About  five  hundred  feet 
above  the  south  base  of  Pequawket,  and  in  the  old  foot-path  (that  of  1840), 
occurs  a  ledge  of  clay  slate,  directly  above  the  granite.  This  formation 
does  not  seem  to  extend  far,  as  it  is  not  found  in  either  of  the  new  paths 
up  the  mountain,  and  a  very  short  distance  from  its  lower  boundary  we 
pass  beyond  it  and  come  upon  the  rock  of  which  the  upper  two  thousand 
feet  of  Pequawket  appears  to  consist,  viz.,  an  igneous  felsite,  full  of  peb 
bles.  The  greater  portion  of  the  included  fragments  are  angular,  slaty, 
lying  at  all  angles,  and  range  in  size  from  an  inch  to  a  foot  in  diameter  ; 
but  the  pebbles,  many  of  them  rounded,  also  occur  very  frequently,  and 
were  all  taken  from  the  rock  in  place.  The  slate  above  referred  to 
runs  N.  70°  E.,  S.  70°  W.,  and  dips  50°  to  80°  N.  W.,  being  much 
twisted  on  a  small  scale.  It  does  not  appear  either  in  the  old  or  new 
roads,  but  in  the  path  of  1840.  Five  hundred  feet  north  and  south  and 
one  thousand  feet  east  and  west  seem  to  include  the  whole  exposure, 
though  further  examination  may  detect  it  elsewhere.  The  upper  part  of 
Pequawket  shows  two  well  marked  systems  of  joints,  which  seem  to 
affect  nearly  the  whole  mountains.  At  the  top,  one  set  runs  S.  60°  W., 
and  dips  about  80°  N.  W. ;  the  other  set  runs  N.  55°  W.,  and  dips  about 
80°  S.  W.  It  will  be  observed  that  the  first  set  agree  almost  exactly 
with  the  strike  and  dip  of  the  slate  in  the  lower  part  of  the  mountain. 
In  many  places  on  the  upper  part  of  the  mountain  the  rock  has  a  thin 
bedded  sort  of  structure  parallel  to  the  jointed  planes ;  but  whether  these 
divisions  indicate  a  real  highly  inclined  bedding  remains  to  be  seen. 

The  slate  lying  above  the  trachytic  granite  is,  in  this  respect,  like  the 
felsites  of  Pemigewasset,  but,  unlike  them,  has  been  much  twisted,  and 
reposes  on  the  top  of  the  terrace,  inclined  at  a  high  angle.  No  doubt 
would  be  entertained  respecting  its  very  much  later  origin  than  the  upper 
two  thousand  feet  of  the  mountain,  except  that  the  latter  is  partly  com-

posed  of  fragments  of  slate,  evidently  derived  from  this  formation.  The 
lower  portions  adjacent  to  the  slate  are  chiefly  composed  of  it,  and  even 
at  the  summit  small  dark  pieces,  apparently  of  the  same  material,  abound. 
A  similar  rock  with  dark  fragments  is  found  on  Twin  mountain.  The 
composition  of  the  cement  shows  it  to  be  allied  in  character  to  the  felsites 
elsewhere  found  overlying  the  trachytic  granite. 

A  somewhat  similar  slate  occurs  between  Mt.  Willard  and  Mt.  Field. 
Specimens  from  the  two  localities  are  not  distinguishable  from  each  other, 
and  the  mass  of  Mt.  Willard  is  a  trachytic  granite.  These  slaty  rocks 
pass  into  quartzites,  if  not  into  felsites,  and  cover  a  considerable  area, 
including  the  country  from  Mt.  Willey  to  beyond  Mt.  Tom,  over  three  miles. 
Well  marked  crystals  of  andalusite  are  found  in  a  similar  slate  on  the 
north-east  spur  of  Mt.  Tom,  which  seems  to  ally  the  series  with  the 
andalusite  slates  of  the  Coos  group  along  the  head  waters  of  Ellis  river, 
at  the  east  side  of  Mt.  Washington.  I  observed  that  jointed  planes 
existed  in  the  trachytic  granite  parallel  with  the  slaty  strata  above 
them  on  Mt.  Willard,  like  those  described  upon  Pequawket.  Passing 
to  the  first  peak  of  Mt.  Field,  the  line  of  union  of  the  granite  and  slate 
was  traversed,  having  a  compass  course  of  N.  25°  W.  In  the  saddle  of 
Mt.  Field  the  slates  dipped  50°  S.  20°  W.  But  on  the  mountains  south 
nothing  is  found  to  correspond  with  the  feldspathic  and  brecciatecl  cap  of 
Pequawket.  The  relations  of  this  slate  to  the  granite  and  felsites  demand 
further  examination. 

RELATIVE  POSITION. 

A  few  considerations  will  serve  to  indicate  the  probable  relative  posi 
tions  of  the  rocks  that  have  been  described.  The  sections  given  of  the 
common  granite,  trachytic  granite,  and  the  felsites,  seem  to  determine 
their  relative  positions,  the  last  being  at  the  top.  The  brecciated  granites 
of  Franconia  appear  to  be  older  than  any  of  these,  and  to  underlie  them, 
as  already  stated;  and  hence  there  may  not  be  any  correspondence 
between  them  and  the  breccias  made  up  of  felsites  and  labradorite.  If 
these  points  are  assumed,  the  porphyritic  gneiss  can  be  shown  to  be  at 
the  bottom  of  the  series,  for  it  lies  outside  of  the  lowest  of  them.  Two 
principal  ranges  of  this  rock  enter  the  limits  of  our  map.  The  eastern 


HISTORY    OF    GEOLOGICAL    SURVEY.  45 

is  cut  off  abruptly  by  the  Labrador  system  at  Waterville,  crossing  at  an 
angle  of  at  least  seventy  degrees,  and  as  much  as  fifty  degrees  in  the  dip. 
Another  exposure  of  the  same  band  of  gneiss  appears  at  the  base  of  Mt. 
Carrigain,  standing  nearly  vertically.  Passing  from  this  across  to  the 
western  range,  we  travel  fifteen  miles.  An  anticlinal  is  hardly  supposa- 
ble  over  so  great  a  distance.  The  dips  have  not  been  observed  system 
atically  ;  but  the  western  range,  from  the  Pemigewasset  to  Moosilauke, 
has  an  anticlinal  form,  and  comes  up  again  west  of  Moosilauke  so  as  to 
underlie  a  synclinal  mass  of  andalusite  schist  or  gneiss.  This  structure 
agrees  with  its  position,  as  deduced  from  other  facts.  The  andalusite 
rock  is  repeated  east  of  the  Pemigewasset  in  an  anticlinal  way,  so  as  to 
correspond,  as  shown  by  its  distribution  on  the  map. 

The  porphyritic  gneiss  west  of  Echo  lake  dips  north-westerly.  At 
the  Lake  of  the  Clouds  the  dip  was  not  measured.  On  the  ridge  running 
south  it  dips  50°  easterly.  Below  Walker's  falls  it  stands  nearly  vertical. 
Our  notes  represent  a  feldspatho-hornblendic  rock  in  horizontal  plates 
immediately  contiguous  on  the  east,  most  likely  lying  upon  the  edges  of 
this  gneiss.  If  this  proves  correct,  then  the  rest  of  the  intermediate 
space  to  the  crest  of  the  range  will  be  found  occupied  by  the  trachytic 
granite,  the  horizontal  plates  showing  its  beginning.  If  the  horizontal 
position  of  the  granites  and  felsites  is  to  be  regarded  as  produced  by 
original  deposition,  then  the  elevation  of  the  gneiss  took  place  first ;  and 
this  mass  of  mountains  has  been  only  slightly  disturbed  by  elevating 
forces  since  that  time. 

The  porphyritic  area  along  the  Ammonoosuc  is  probably  a  repetition  of 
that  near  Echo  lake,  making  a  synclinal  axis,  just  as  in  Benton,  under 
Moosilauke.  With  this  premise  we  can  infer  that  the  gneiss  of  Bethlehem 
was  formed  subsequently,  and  lies  in  a  basin,  with  an  east  and  west  axis. 

We  cannot  as  yet  locate  the  andalusite  gneiss,  save  that  it  is  newer  than 
the  porphyritic  bands,  as  shown  at  Moosilauke. 

There  is  one  further  suggestion  in  respect  to  relative  ages.  The  Coos 
group  of  Littleton  and  Lisbon  passes  around  the  west  end  of  the  Bethle 
hem  gneiss,  showing  that  the  latter  existed  before  either  the  deposition 
or  elevation  of  the  former.  This  indicates  that  the  whole  of  the  White 
Mountain  rocks  are  more  ancient  than  the  Cods  and  Quebec  groups  of 
the  Connecticut  valley.

MAP  SURVEYS  AND  LEVELLING. 


Some  of  the  new  material  obtained  for  perfecting  the  map  in  1870  was 
the  following  : 

First,  a  new  map  of  Connecticut  river,  from  Massachusetts  to  Connec 
ticut  lake.  Part  of  this  was  surveyed  in  1825,  with  the  expectation  that 
a  canal  would  be  built  along  the  river,  as  high  as  Mclndoe's  falls,  in  Bath. 
This  very  valuable  map  was  presented  to  the  survey  by  Dr.  E.  E.  Phelps, 
of  Windsor,  Vt.  It  is  superior  to  the  county  maps  or  the  state  map  of 
Vermont,  and  is  therefore  the  best  one  in  existence.  It  represents  things 
as  they  were  in  1825;  but  there  has  been  little  change  since  that  time 
except  in  the  construction  of  new  turnpikes  and  railroads. 

Second,  Messrs.  Walling  and  Gray  were  employed  late  in  the  season  to 
prepare  a  map  of  the  river  between  Bath  and  Connecticut  lake,  from  new 
surveys.  This  has  been  done  carefully,  and  constitutes  a  very  important 
addition  to  our  materials  for  the  final  map.  These  same  engineers  also 
made  careful  odometer  surveys  of  the  Mt.  Washington  carriage  road  and 
the  Fabyan  turnpike,  which  are  in  our  possession. 

We  commenced  this  year  the  preparation  of  a  raised  map  of  the  state, 
for  the  museum,  upon  the  scale  of  one  mile  to  the  inch.  The  table  to 
serve  as  its  foundation  was  placed  in  position,  and  nearly  all  the  outside 
boundaries  of  the  state  drawn  upon  it.  In  1871  Mr.  Huntington  drew 
contour  lines  for  all  of  Coos  county  north  of  Shelburne  and  Lancaster, 
from  which  the  north  portion  of  the  model  has  been  constructed.  At  the 
same  time  I  constructed  a  plan  of  the  Franconia  and  Bethlehem  moun 
tains  upon  a  much  larger  scale.  This  was  designed  to  illustrate  the 
theory  of  Prof.  Agassiz  respecting  the  northward  transportation  of  boul 
ders  by  a  local  glacier  from  the  Franconia  Mountains. 

Additional  work  upon  the  model  of  the  whole  state  was  performed  in 
1873.  It  will  not  be  best  to  complete  this  until  the  last  item  of  facts  con 
cerning  the  topography  of  the  state  has  been  garnered  in.  The  general 
facts  upon  which  this  is  based  will  appear  in  the  chapter  upon  topography. 
The  surveying  necessary  for  the  mapping  of  a  part  of  the  Ammo- 
noosuc  gold  field,  referred  to  heretofore,  was  completed  in  1870.  The 
last  part  of  the  work,  setting  the  stakes  for  more  than  two  square  miles, 


HISTORY    OF    GEOLOGICAL    SURVEY.  47 

was  performed  under  the  direction  of  Prof.  Quimby.  The  map  shows 
the  courses  of  all  the  valuable  mineral  veins  existing  upon  the  tract,  as 
well  as  the  remarkable  windings  and  dislocations  of  the  formations  which 
are  there  exhibited.  Not  less  than  five  hundred  specimens  were  collected 
to  illustrate  this  map. 

A  TRIGONOMETRICAL  SURVEY. 

By  an  act  passed  in  1871,  congress  authorized  the  coast  survey  to 
expend  a  considerable  sum  of  money  in  extending  their  triangulations 
into  the  interior,  but  only  for  those  states  where  a  geological  survey  is  in 
progress.  New  Hampshire  is  the  only  one  of  the  New  England  states 
which  has  so  far  received  any  benefit  from  this  act,  and  the  annual  appro 
priation  for  this  purpose  has  not  been  less  than  $2,000.  The  work  has 
been  placed  in  the  hands  of  Professor  E.  T.  Quimby,  of  Dartmouth 
college.  He  first  occupied  the  stations  established  in  1869  for  the  benefit 
of  the  geological  survey,  so  as  to  verify  their  accuracy.  The  work  has 
been  successfully  carried  on  now  for  three  seasons,  and  the  latitudes  and 
longitudes  thus  obtained  are  given  in  the  chapter  on  topography. 

LEVELLING  ALONG  CONNECTICUT  RIVER. 

For  the  sake  of  a  proper  understanding  of  the  surface  geology  of 
Connecticut  river,  it  has  been  thought  best  to  level  from  the  Massachu 
setts  line  to  Connecticut  lake.  The  work  was  commenced  in  1870  by 
Gyles  Merrill,  Jr.,  and  S.  Q.  Robinson,  of  the  class  of  1872,  C.  S.  D., 
Dartmouth  college.  They  have  levelled  between  the  line  and  Walpole. 
Mr.  Merrill  was  assisted  also  by  his  brother.  The  line  from  Bellows 
Falls  to  Windsor  was  levelled  by  Warren  Upham  in  1874.  The  work 
above  Hanover  was  performed  in  1871,  under  the  direction  of  A.  F.  Reed, 
of  Groton,  Mass.,  assisted  between  Hanover  and  Lancaster  by  Dr.  Nathan 
Barrows,  of  Meriden,  and  between  Lancaster  and  Connecticut  lake  by 
Messrs.  C.  F.  and  F.  A.  Bradley,  of  the  class  of  1873,  Dartmouth  college. 
The  connection  between  this  survey  and  that  of  the  P.  &  O.  Railroad,  at 
Dalton,  was  made  by  J.  T.  Woodbury  in  1874. 

In  the  report  for  1871  there  appears  a  long  list  of  altitudes,  including 
all  that  had  been  obtained  by  special  surveys  at  that  time.  These  are 
to  be  given  more  fully  in  a  following  chapter,  with  many  additions  and 
improvements.

MICROSCOPICAL   RESEARCHES. 


In  view  of  the  importance  of  microscopical  researches,  not  only  in 
gaining  knowledge  of  the  mineral  structure  of  rocks,  but  also  of  the 
"  polishing  powder"  and  other  valuable  minerals  abundant  in  the  state, 
we  organized  a  new  department  of  the  survey  in  1870,  and  obtained  the 
assistance  of  Professor  A.  M.  Edwards,  of  Newark,  N.  J.,  and  Professor 
T.  Egleston,  of  the  School  of  Mines,  Columbia  college,  New  York. 
Professor  Edwards  has  prepared  an  extensive  report  upon  the  organisms 
producing  the  lacustrine  sedimentary  deposits  ;  and  Professor  Egleston 
has  had  charge  of  the  cutting  and  description  of  rock  sections. 

FOSSILS  ix  NEW  HAMPSHIRE. 

In  October,  1870,  while  examining  the  limestones  of  Littleton,  fossil 
corals  were  discovered.  They  were  quite  numerous,  though  obscure.  In 
telligence  of  the  discovery  was  immediately  telegraphed  to  the  Dartmouth 
Scientific  Association,  who  happened  to  be  holding  a  meeting  the  same 
evening.  It  was  announced  to  them  that  New  Hampshire  could  no 
longer  be  called  an  Azoic  state,  since  she  had  within  her  borders  a  coral 
reef  of  Silurian  age. 

Specimens  were  sent  to  E.  Billings,  F.  G.  S.,  paleontologist  of  the 
geological  survey  of  Canada,  who  recognized  the  genera  Zaphrentis  and 
Favosites,  and  perceived  the  probable  equivalency  of  these  limestones 
with  the  Helderberg  series  of  Memphrcmagog.  The  band  of  rock  was 
at  first  supposed  to  be  the  same  with  the  limestones  of  Dalton  and 
Lancaster,  and  perhaps  farther  north.  The  fossils  have  been  discov 
ered  in  two  localities,  nearly  two  miles  apart,  upon  what  is  thought  to  be 
the  two  sides  of  a  synclinal  axis.  The  limestone  is  underlaid  by  a 
quartzite  and  covered  by  a  clay  slate,  the  latter  containing  impressions  of 
worm  tracks.  Though  previously  announced,  this  is  believed  to  be  the 
first  authentic  discovery  of  fossils  in  the  solid  rocks  of  New  Hampshire. 

No  time  could  be  devoted  to  this  interesting  department  till  1873,  when 
our  labors  were  rewarded  by  the  discovery  of  fossils  characteristic  of  the 
Lower  Helderberg.  Mr.  Huntington  was  so  fortunate  as  to  find,  on 
Fitch  hill,  Littleton,  specimens  of  brachiopods,  a  gasteropod,  and  large 


HISTORY    OF    GEOLOGICAL    SURVEY.  49 

crinoidal  stems.  Mr.  Billings  reports  that  the  brachiopod  is  allied  to  the 
Pcntauicrns  Knightii  of  the  Lower  Helderberg ;  and  that  the  gasteropod 
is  also  like  one  in  the  same  formation.  The  crinoidal  fragments  place 
this  deposit  in  correlation  with  the  noted  bed  at  Bernardston,  Mass.,  first 
described  by  my  father  in  1833.  Geologists  had  supposed  the  latter  bed 
to  be  of  Devonian  age,  because  the  large  crinoids  seemed  like  those  from 
the  Corniferous  beds  in  New  York ;  but  our  discoveries  serve  to  modify 
this  conclusion.  Considerable  attention  was  devoted  to  the  Helderberg 
deposits  by  us  in  1873,  and  we  have  been  enabled  to  derive  most  impor 
tant  generalizations  respecting  the  structure  of  the  state,  second  in 
importance  only  (though  most  would  value  them  more  highly)  to  the 
results  of  the  White  Mountain  exploration.  A  lengthy  sketch  of  the 
New  Hampshire  Helderberg  rocks  has  been  published  in  the  American 
Journal  of  Science  for  April,  1874.  Our  next  volume  will  treat  the  sub 
ject  with  all  the  detail  required. 

QUARTZITES    IN    THE    GNEISS. 

Hon.  S.  N.  Bell,  of  Manchester,  pointed  out  to  me,  before  commenc 
ing  the  New  Hampshire  survey,  the  occurrence  of  interesting  bands  of 
quartzite  in  the  southern  part  of  the  state.  As  soon  as  occasion  offered, 
an  examination  of  them  was  commenced.  Mr.  Bell  often  accompanied  us 
on  our  expeditions,  and  for  his  own  pleasure  traced  out  thirty  or  forty 
miles  of  their  extent.  In  1871,  in  company  with  Mr.  L.  Holbrook,  the 
limits  of  these  bands  were  studied  in  Hillsborough,  Merrimack,  and 
Strafford  counties.  The  results  of  our  examination  indicated  that  these 
two  bands  of  quartzite  traverse  a  tract  of  country,  often  in  a  serpentine 
course  parallel  to  each  other,  eight  or  ten  miles  apart,  from  Temple  to  the 
north  part  of  Strafford  on  one  line,  and  from  New  Ipswich  to  the  south 
part  of  Strafford  on  the  other.  Beyond  this  point  the  formations  seem 
to  be  covered  by  the  andalusite  schists. 

After  passing  a  wide  band  of  gneiss  to  the  west  of  the  Temple-Straf- 
ford  range,  we  came  to  a  belt  of  porphyritic  gneiss,  which  seems  to  be 
the  oldest  formation  in  the  state.  In  accordance  with  this  view  of  the 
relative  ages  of  the  formations,  we  find  similar  rocks  west  from  this  cen 
tral  porphyritic  gneiss.  The  studies  commenced  by  G.  A.  Wheelock,  of 
Keene,  have  brought  to  light  two  beds  of  the  same  quartzites  in  Keene 
VOL.  r.  7 


jo  PHYSICAL    GEOGRAPHY. 

and  Surry,  separated  by  a  wide  band  of  gneiss  from  the  central  group. 
As  the  same  rock  appears  in  Grafton  and  Newport,  fifty  or  sixty  miles 
farther  north,  it  is  likely  the  same  arrangement  continues  past  the  centre 
of  the  state;  while  the  descriptions  of  my  father,  in  the  final  report  on 
the  geology  of  Massachusetts,  speak  of  a  white  quartzite  having  the  same 
relations,  midway  through  that  commonwealth.  Neither  this,  nor  the 
band  of  porphyritic  gneiss  mentioned  as  passing  nearly  north  and  south 
from  New  Hampshire  to  Connecticut,  on  the  meridian  of  Ware,  was 
represented  upon  his  map,  as  their  importance  was  not  appreciated. 

In  the  report  for  1872,  a  map  of  the  southern  part  of  New  Hampshire 
was  presented  for  the  purpose  of  showing  the  course  of  these  quartzite 
bands.  The  following  statements  were  made  respecting  them  : 

Our  map  shows  two  nearly  parallel  ranges  of  quartzites, — the  one  extending  from 
Allenstown  to  Mason,  and  the  other  from  the  same  town  to  Temple.  Diligent  search 
has  failed  to  reveal  any  traces  of  these  bands  beyond  Allenstown,  which  surely  belong 
to  them.  Inasmuch  as  the  accompanying  gneisses  also  terminate, — both  those  included 
between  the  ranges,  and  the  crumpled  granitic  gneiss  to  the  south-east, — and  the  mica 
schists  beyond  seem  to  have  taken  a  northerly  course,  we  conclude  that  the  continua 
tion  of  all  those  strata  is  concealed  by  the  overlying  blanket  of  mica  schist.  The 
map  shows  how  completely  these  bands  are  interrupted  by  the  newer  schists.  Nothing 
has  yet  been  suggested  to  account  for  the  termination  of  the  quartzite  bands  in  Temple 
and  Mason.  Further  search  may  reveal  them  on  the  same  line  in  Massachusetts. 

The  map  shows  these  quartzites  in  Richmond,  Keene,  Surry,  and  Grafton,  on  the 
west  side  of  the  porphyritic  range.  We  have  not  yet  been  able  to  trace  them  out  in 
that  part  of  the  state.  These  ranges  have  been  seen  in  Massachusetts,  especially  in 
New  Salem.  Their  occurrence  in  two  bands  on  both  sides  of  the  main  anticlinal  will 
furnish  us  the  general  clue  to  the  stratigraphical  structure  of  the  gneiss,  besides  making 
plain  the  line  of  the  granites  and  soapstone, — for  there  is  a  range  of  the  latter  mineral 
accompanying  the  Keene  quartzites.  It  will  be  observed  that  the  latter  curve  around 
the  older  porphyritic  rocks  of  Swanzey. 

It  is  almost  exciting  to  follow  the  hills  of  this  rock  through  the  towns.  They  can  be 
seen  miles  away,  being  as  white  as  snow.  The  following  are  the  most  notable  hills 
along  its  course  :  In  East  Concord,  Oak  hill ;  West  Concord,  Pine  hill ;  on  the  Temple 
range,  the  foundations  of  the  upper  railroad  bridge,  and  the  Pinnacle  in  Hooksett ; 
the  hill  of  quartz  quarried  for  the  manufacture  of  glass  in  Lyndeborough,  and  a  long 
ridge  in  Temple  extending  north-easterly  from  the  village ;  on  the  Mason  range,  a 
high  hill  north-east  from  East  Wilton  ;  the  north-east  corner  of  Amherst ;  and  Campbell 
hill  in  Hooksett.  The  ranges  are  6.20  miles  apart  in  New  Boston  and  Bedford, 
narrowing  to  3.12  in  Hooksett,  and  5  miles  in  Wilton.  The  most  remote  localities  in 


HISTORY    OF    GEOLOGICAL    SURVEY.  51 

Temple  and  Mason  are  6£  miles  distant  from  each  other.     The  Mason  range  does  not 
curve  to  the  west,  as  erroneously  shown  upon  the  map. 

There  are  also  ranges  of  quartzite  in  the  mica  schist  group.  The  most  extensive  is 
in  Raymond  and  Nottingham.  Other  outcrops  are  in  Londonderry,  Strafford,  and 
Pittsfield.  Those  in  Strafford  were  formerly  regarded  as  the  extension  of  the  Temple 
and  Mason  ranges. 

MUSEUM. 

Work  has  steadily  progressed,  during  the  continuance  of  the  survey^ 
upon  the  museum.  Culver  hall  contains  the  specimens  designed  for  the 
New  Hampshire  College  of  Agriculture  and  the  Mechanic  Arts ;  but  the 
Concord  collection  still  remains  packed  in  boxes.  Briefly,  the  special 
features  of  the  museum  are  the  following :  A  room  about  forty  feet  square 
is  set  apart  for  the  illustration  of  the  geology,  mineralogy,  paleontology, 
botany,  and  zoology  of  New  Hampshire  and  Vermont.  It  is  designed  that 
every  department  shall  be  represented  complete  and  entire.  Only  the  col 
lections  of  the  survey  have  been  presented  by  the  state ;  but  earnest  efforts 
are  put  forth  to  secure  the  remainder  by  aid  from  friends  of  Dartmouth  col 
lege.  This  institution  being  nearly  the  geographical  centre  of  two  states, 
it  seems  an  appropriate  place  for  this  gathering  of  representations  of 
their  natural  products  and  resources.  The  room  now  contains,  first,  and 
the  most  prominent  feature,  fourteen  shelves,  holding  specimens  collected 
along  fourteen  east  and  west  lines  across  New  Hampshire.  Several  of 
the  section  lines  have  been  carried  across  to  Lake  Champlain.  Behind 
each  shelf  is  a  colored  profile  of  the  route  taken,  drawn  to  an  exact 
scale  for  heights  and  distances,  each  formation  being  distinguished  from 
every  other,  the  names  of  the  groups  and  localities  printed  in  large 
letters,  numbers  placed  on  the  section  to  show  the  exact  locality  of  every 
specimen,  and  the  rocks  appear  in  the  immediate  proximity  of  the  figures 
on  the  wall.  Lithological  specimens,  obtained  between  the  section  lines, 
are  placed  on  the  shelf  in  their  proper  relations,  but  not  so  as  to  be 
confounded  with  the  others.  There  is  also  a  series  of  large  maps  of  the 
northern  townships  (and  eventually  there  will  be  of  all  the  rest),  showing 
the  topographical  position  of  every  lithological  specimen  in  the  collection. 
If  possible,  these  will  be  reproduced  for  the  report.  Second,  the  room 
contains  several  sets  of  specimens,  properly  catalogued,  to  illustrate  more 


52  PHYSICAL    GEOGRAPHY. 

fully  important  areas.  They  are  the  White  Mountain  area,  the  Ammo- 
noosuc  gold  field  (including  the  Lyman  map  district),  and  the  towns 
adjacent  to  Hanover.  Third,  a  special  collection  of  minerals ;  fourth,  of 
fossils;  fifth,  of  all  economic  materials,  particularly  the  granites  of  New 
Hampshire,  and  the  marbles  and  slates  of  Vermont;  sixth,  a  special  set  to 
illustrate  the  distribution  of  boulders ;  seventh,  numerous  topographical 
models. 

The  college  collections  embrace,  first,  most  of  our  birds,  collected  and 
presented  by  Prof.  Henry  Fairbanks,  of  St.  Johnsbury,  Vt;  second,  one 
thousand  species  of  New  Hampshire  insects,  collected  by  C.  P.  Whitney, 
of  Milford,  and  presented  by  Mr.  Fairbanks ;  third,  a  few  mammals,  by 
the  same ;  fourth,  miscellaneous  New  Hampshire  fish  and  reptiles ;  fifth, 
the  plants  of  the  White  Mountains,  collected  by  the  survey,  and  the  local 
flora  of  Hanover, — the  latter  gathered  and  presented  to  Dartmouth  college 
by  Miss  Mary  Hitchcock,  of  Hanover. 

The  state  house  collection  ought  to  be  equally  comprehensive;  but  at 
present  there  are  no  rooms  suitable  for  its  accommodation. 

THE  Mr.  WASHINGTON  EXPEDITION. 

The  chief  part  of  the  report  for  1870  is  occupied  by  a  sketch  of  the 
Mt.  Washington  expedition.  The  meteorological  tables  are  given  in  full ; 
and,  side  by  side  with  them,  observations  from  several  other  localities, 
taken  at  the  same  hours,  for  purposes  of  comparison.  Mr.  S.  A.  Nelson 
furnishes  an  admirable  sketch  of  the  meteorology  of  Mt.  Washington, 
following  the  tables.  His  great  skill  in  generalizing  from  facts  will  cause 
great  regret  that  he  was  unable  to  prepare  for  this  volume  a  sketch  of  the 
meteorology  of  the  state. 

MR.  HUNTINGTON'S  LABORS. 

We  have  been  greatly  favored,  through  most  of  our  labors,  by  the  per 
severance  of  Mr.  J.  H.  Huntington,  principal  assistant.  He  has  entered 
thoroughly  into  the  spirit  of  the  work,  and  has  fully  identified  himself 
with  our  explorations.  Though  having  a  special  field  of  his  own,  he  has 
always  been  ready  to  labor  elsewhere  whenever  assistance  was  required. 
The  following  is  a  general  outline  of  his  work  since  the  last  mention  of 


HISTORY    OF    GEOLOGICAL    SURVEY.  53 

him:  In  the  early  part  of  18/0,  he  traversed,  on  foot,  the  various  moun 
tain  notches  between  the  Saco,  Pemigewasset,  and  Connecticut  rivers,  for 
the  purpose  of  ascertaining  their  altitudes.  Next  he  renewed  the  exami 
nation  of  the  rocks  of  Coos  county.  Afterwards  he  joined  our  party  in 
the  White  Mountain  explorations.  Later  in  the  season  he  continued  the 
exploration  in  Coos  county  and  Bean's  purchase.  Later  in  the  fall  he 
devoted  himself  to  the  interests  of  the  Mt.  Washington  meteorological 
expedition,  attending  to  the  completion  of  the  arrangements  for  occupy 
ing  the  railroad  depot  as  an  observatory.  The  six  months  from  the  middle 
of  November  to  the  middle  of  May  were  spent  by  him  mostly  upon  the 
summit,  where  he  was  the  leader  of  the  heroic  party  who  risked  their 
lives  in  behalf  of  science.  When  this  task  was  completed,  he  resumed 
his  work  upon  the  geology  of  Coos  county  in  1871,  being  occupied  until 
late  in  July  with  the  compilation  of  his  report  upon  the  geology  of  Coos 
county.  He  then  took  the  field  and  labored  in  the  northern  part  of  the 
state,  also  in  Essex  county,  Vt, — the  latter  without  cost  to  the  survey, 
though  we  receive  the  benefits  of  the  exploration.  In  September  he 
examined  the  formations  near  Jackson,  Bartlett,  Comvay,  Albany,  etc., 
partly  to  carry  on  the  search  for  labradorite  rocks. 

Essentially  the  same  field  was  traversed  by  him  in  the  summer  of  1872. 
His  researches  in  Albany  will  be  found  of  special  importance.  In  1873, 
after  the  completion  of  the  exploration  in  the  northern  part  of  the  state, 
he  commenced  working  in  the  gneissic  district  lying  between  the  main 
range  of  porphyritic  gneiss  on  the  east,  and  the  Connecticut  valley  Coos 
group.  The  sketch  of  the  geology  of  this  tract  will  be  written  by  him  as 
soon  as  possible.  In  the  first  volume,  the  chapter  on  meteorology  has  been 
prepared  by  him ;  also,  topographical  and  scenographical  contributions. 

MISCELLANEOUS. 

Very  much  remains  to  be  told  of  the  history  of  our  scientific  ex 
plorations  ;  but  we  fancy  it  will  be  more  satisfactory  to  read  the  com 
pleted  results  than  to  learn  how  they  have  been  effected.  In  the  reports 
there  has  been  a  fine  series  of  rock  analyses  by  Profs.  Seely  and  Blan- 
pied;  outline  sketches  of  the  subject-matter  of  this  series  of  volumes; 
the  progress  of  the  microscopical  department ;  additional  meteorological 


e 4  PHYSICAL   GEOGRAPHY. 

tables  from  Mt.  Washington  and  Hanover ;  and  a  sketch  of  the  geology 
of  southern  New  Hampshire.  The  map  illustrating  it  shows  the  follow 
ing  formations  between  the  Exeter  sicnites  and  the  Coos  group,  along 
Connecticut  river,  given  in  the  supposed  order  of  their  age: 

1.  Porphyritic  gneiss  and  granite. 

2.  Granitic  gneiss. 

3.  White  Mountain  series,  including  andalusite  gneiss,  ordinary  and 
imperfect  gneiss,  the  so-called  granite  of  Concord  and  Fitzwilliam,  beds 
of  soapstone  and  limestone. 

4.  Bands  of  quartzite. 

5.  Mica  schist. 

6.  Andalusite  slates  or  outliers  of  the  Coos  group.     Of  these  the  map 
distinguishes  the  porphyritic  group,  the  quartzite  bands,  the  mica  schist, 
and  the  Coos  outlier.     The  other  gneiss,  being  yet  known  imperfectly,  I 
will  not  attempt  to  divide. 

The  following  remarks  concerning  the  second  group  may  be  quoted, 
as  this  had  not  been  distinguished  from  the  adjacent  groups  before. 

There  is  decided  evidence  of  a  range  of  very  ancient  gneiss  from  Mason  to  Deerfield. 
It  abounds  in  feldspar;  the  strata  are  very  highly  inclined  and  remarkably  plicated. 
It  is  very  granitic,  so  much  so  that  but  a  slight  additional  metamorphic  action  would 
be  needed  to  obliterate  all  the  planes  of  stratification.  This  formation  is  probably 
repeated  west  of  the  quartzite  ranges,  and  also  in  Cheshire  and  Sullivan  counties. 
The  character  of  the  strata,  and  the  superabundance  of  feldspar,  readily  distinguishes 
it  from  everything  else. 

Also,  a  few  words  about  the  "Concord  granite,"  and  the  "mica  schist" 
of  Rockingham  county. 

The  "Concord  granite"  has  been  traced  irregularly  from  Concord  to  Fitzwilliam. 
It  will  require  more  detailed  examinations  to  enable  us  to  say  positively  where  this 
valuable  band  may  be  found.  It  seems  to  lie  near  the  quartzite,  say  from  a  quarter  to 
half  a  mile  above  it.  Hence,  if  it  exists  as  a  range,  it  should  be  adjacent  to  all  the 
quartzite  bands,  and  its  distribution  can  be  determined  readily  in  the  manner  suggested 
above.  A  section  across  these  ranges  near  Manchester  shows  a  similar  granite  inside 
both  of  them,  while  a  protracted  examination  has  failed  to  show  the  quartzite  beyond 
the  west  part  of  Concord.  This  rock  is  not  a  proper  granite.  There  is  an  arrangement 
of  the  particles  of  mica  along  parallel  planes,  which  allows  the  rock  to  split  readily. 
These  we  regard  as  strata.  They  are  seen  plainly  in  the  inferior  qualities  of  the  stone, 
and  farther  south  the  celebrated  "granite"  of  Pelham  and  Monson,  Mass.,  shows  the 


HISTORY    OF    GEOLOGICAL    SURVEY.  55 

strata  perfectly.  The  latter  appear  to  be  identical  with  the  Concord  stone.  Micro 
scopic  sections,  when  available  for  study,  will  add  much  to  our  knowledge  of  this 
variety  of  rock. 

By  scrutinizing  the  course  of  a  band  of  rock  closely  packed  with  andalusite,  it 
appears  probable  that  the  valuable  soapstone  of  Francestown  is  continuous  into  Weare, 
as  well  as  extending  farther  south-west.  Outcrops  have  been  found  in  four  localities. 
The  soapstone  of  Richmond  resembles  it  also,  and  seems  to  be  on  the  same  course. 
Hon.  M.  A.  Hodgdon,  of  Weare,  has  made  an  extensive  excavation  in  this  bed  on  Mt. 
Misery,  which  throws  considerable  light  on  its  character. 

Mica  Schist.  This  formation  covers  a  great  area  in  Rockingham  and  Strafford 
counties.  In  general  it  is  a  simple  compound  of  mica  and  quartz,  resembling  an 
argillaceous  rock  at  times,  and  often  showing  the  mica  in  irregular  blotches.  It  every 
where  contains  beds  of  a  very  coarse  granite.  In  the  south  part  of  Rockingham,  in 
Barrington,  Strafford,  and  elsewhere,  the  granite  remains  in  ridges,  while  the  schist  has 
decomposed,  thus  making  one  believe  granite  to  be  the  prevailing  rock  of  the  country, 
without  careful  search  for  the  schist  in  the  valleys. 

The  sienites  of  Exeter  bound  this  group  on  the  east.  The  Merrimack  group  seems 
to  be  distinct  from  it,  though  the  two  have  been  confounded  together  heretofore. 
This  rock  forms  mountain  masses  in  many  towns.  Such  are  the  ridges  between  Hill's 
Corner  and  Shaker  Village  in  Canterbury,  the  Pinnacle  and  Bean  hill  in  Northfield, 
Catamount  Mount  in  Pittsfield,  Brush  hill,  McKays,  Fort,  and  Nottingham  mountains 
in  Epsom,  Saddleback  Mount  in  North  wood,  Devil's  Den  in  Auburn,  ridges  in  Farm- 
ington,  etc.  Narrow  patches  of  mica  schist  occur  resting  in  synclinal  form  on  the 
gneiss  west  of  the  Merrimack  river,  but  it  is  of  no  use  to  attempt  to  represent  them 
at  present. 

GEOLOGICAL  HISTORY  OF  WINNIPISEOGEE  LAKE. 

The  results  of  a  tour  in  the  vicinity  of  Winnipiseogee  lake,  in  1873,  are 
given  in  a  lengthy  paper  read  before  the  American  Association  for  the 
Advancement  of  Science,  at  Portland,  in  August.  The  greatest  detail  of 
the  sketch  relates  to  the  supposed  appearance  of  the  lake  country  in  the 
glacial  and  terrace  periods,  which  need  not  be  reproduced  here.  But  I 
desire  to  state  the  phase  of  opinion  expressed  in  this  communication 
respecting  the  older  groups.  A  large  manuscript  map  illustrated  to  the 
geologists  at  the  meeting  the  distribution  of  the  formations  deposited  in 
the  several  periods  enumerated.  There  are  some  new  groups  in  this  list. 
We  can  trace  no  less  than  ten  periods  in  the  history  of  this  lake  basin : 
i.  Period  of  the  deposition  of  the  Po rpJiyritic  Gneiss  or  Granite.  This 
is  the  oldest  formation  in  the  state.  A  range  of  it  starts  southerly  from 


5  6  PHYSICAL    GEOGRAPHY. 

\Vaterville,  and  proceeds  south-westerly  to  Mt.  Prospect,  in  Holderness. 
Thence  it  courses  more  southerly,  proceeding  to  New  Hampton  centre 
village.  In  this  vicinity  it  is  developed  more  perfectly  than  in  any  other 
part  of  the  state.  At  the  village  it  makes  a  sharp  turn  eastward  to  Mer 
edith  Village ;  thence  north-easterly  nearly  to  Squam  lake,  in  the  extreme 
north-east  part  of  Center  Harbor.  It  then  makes  another  sharp  turn 
down  both  sides  of  Meredith,  or  North-west  Cove,  and  appears  also  on  the 
islands  off  Wiers  and  the  north  part  of  Gilford.  It  now  rapidly  dimin 
ishes  in  width,  and  finally  disappears,  coming  up  again  in  West  Alton,  and 
is  last  seen  in  the  south  part  of  Alton. 

2.  Winnipiseogce  Lake  Gneiss  formation.     This   is    a  granitic   gneiss 
filled  with  segregated  veins,  and  has  not  yet  been  observed  away  from 
the  vicinity  of  the  lake.     It  does  not  appear  upon  any  mountains,  nor  in 
bluffs,  and  has  everywhere  been  greatly  denuded,  so  that  its  ledges  are 
inconspicuous.      It  joins  the  first  named  rock  everywhere  on  the  east, 
and  covers  it  in  Alton.     The  strata  are  highly  inclined,  and  sometimes 
inverted. 

3.  WJiite  Mountain  Scries.     This  rock  is  often  characterized  by  the 
presence  of  andalusite.     It  crops  out  in  Gilford  and  Alton,  and  bounds 
the  lake  gneiss  on  the  east,  where  the  junction  is  not  obscured  by  over 
lying  formations. 

4.  The  next  great  period  may  represent  the  time  of  the  elevation,  and 
perhaps  metamorphosis,  of  the  three  groups   already  enumerated.     We 
possess  no  decided  evidence  to  show  that  these  three  groups  are  uncon- 
formable  with  one  another.     The  presumption  is  that  these  groups  belong 
to  the  Laurentian  system ; — they  are  certainly  Eozoic. 

5.  Eruption  of  tJie  Granites  of  the  Ossipee  Mountains.     In  a  paper 
presented  last  year,  a  description  was  given  of  the  rocks  among  the  White 
Mountains,  where  it  was  stated  that  the  upturned  edges  of  the  White 
Mountain  series  were  covered  first  by  a  layer  of  coarse  granite,  and  then 
by  a  "trachytic"  or  spotted  granite.     Both  these  varieties  arc  found  in 
the  Ossipee  mountains,  and  in  a  similar  stratigraphical  position. 

6.  Deposition  of  Felsites  or  Compact  Feldspars.     Enormous  thicknesses 
of  variously  colored  felsites  cover  the  spotted  granite  of   Ossipee,  and 
form  the  summits  of  the  pile  of  mountains.     None   of   the  ossipyte,  a 
compound   of   labradorite  and   chrysolite,  has   yet   been   seen.      These 


HISTORY    OF    GEOLOGICAL    SURVEY.  57 

granites  and  felsites  together  constitute  a  great  series  of  formations, 
which,  I  suppose,  are  the  equivalents  of  the  Labrador  system  of  Logan. 
He  has  not  given  the  limits  of  his  system ;  but  I  retain  the  name  sug 
gested  by  him  for  the  group  of  granites  and  compact  feldspars  developed 
so  finely  in  New  Hampshire.  There  is  an  extensive  mass  of  granite  in 
Wolfeborough  and  New  Durham,  which  may  be  connected  with  the 
Labrador  system,  but  its  relations  have  not  yet  been  made  out  with 
certainty. 

7.  Eruption  of  Sicnite.     The    Belknap   Mountains,   certain    peaks   in 
Alton,  Diamond  island,  and  probably  Rattlesnake  island  in  Winnipiseogee 
lake,  and  Red  hill  in  Moultonborough  and  Sandwich,  are  composed  of 
sienite  of  various  textures,  which  seems  to  have  been  erupted  after  the 
deposition  of  the  felsites.     Its  age  is  shown  by  the  fact  that  it  cuts  the 
ossipyte  in  Waterville. 

8.  Deposition  of  Mica  Schists.     This  formation  is  enormously  devel 
oped  in  Strafford  and  Rockingham  counties,  touching  the  lake  only  at 
Alton  Bay.     It  evidently  covers  all  the  formations  thus  far  specified. 

This  is  the  last  of  the  solid  rocks  in  this  area.  There  succeeds  an 
enormous  interval  of  time,  of  which  we  have  no  record  in  New  Hamp 
shire.  The  country  must  have  been  elevated,  so  that  no  deposits  could 
be  formed.  The  interval  embraces  the  principal  portion  of  the  fossil- 
iferous  rocks. 

9.  Glacier  Period.     The  phenomena  of  this  age  about  the  lake  are 
striae,  embossed  ledges,  pot-holes,  beds  of  clay,  boulder  drift,  etc.     The 
courses  of   the    striae  usually   agree  with  that  of   the   valley,   or  from 
S.  25°-30°E. 

10.  The  Terrace  Period.     The  presence  of  the  ocean  after  the  glacial 
period  over  the  lake  may  possibly  be  indicated  by  the  existence  of  the 
smelts  in  its  waters,  which  are  marine  animals,  possibly  left  behind  when 
the  salt  water  disappeared.     The  terraces  seem  to  indicate  that  the  water 
has  stood  successively  at  the  heights  of  100,  80,  55,  30,  23,  15,  and  12 
feet,  but  never  any  higher.     There  may  have  been  egress  for  the  waters 
in  the  direction  of  Squam  lake,  Gilford,  and  Alton. 

Lengthy  considerations  are  presented  to  show,  by  contrast  to  these 
small  lake  terraces,  the  fluviatile  origin  of  the  large  banks  of  sand  and 
gravel  along  the  Merrimack  river  valley.     The  conclusions  are  of  consid-

erable  importance,  and  will  be  fully  developed  in  that  part  of  our  report 
relating  to  surface  geology.

CHAPTER    IV. 


HISTORY    OF    EXPLORATIONS    AMONG   THE   WHITE    MOUNTAINS. 


COMPILED    BY   WAKREN   UPHAM. 


FIRST  VISITS  TO  MT.  WASHINGTON. 

IHE  early  history  of  the  White  Mountains  may  well  be  of  interest  to 
all  who  feel  a  pride  in  the  beautiful  scenery  or  in  the  material  pros 
perity  of  this  portion  of  our  state.  It  is  only  a  meagre  record,  however, 
that  we  are  able  to  present.  Even  the  name  of  the  first  adventurer  who 
ascended  these  mountains  was  for  some  time  uncertain.  It  was  stated  by 
Dr.  Belknap,  in  the  early  editions  of  his  history  of  New  Hampshire,  that 
Walter  and  Robert  Neal  were  the  first  to  climb  the  highest  summit  of  the 
White  Mountains,  in  1631.  This  appears  to  be  incorrect;  and  the  error 
was  noticed  by  the  author  in  the  edition  of  1812.  It  is  now  considered 
settled  that  this  credit  is  to  be  assigned  to  Darby  Field,  of  Pascataquack 
(Portsmouth),  who  made  the  ascent,  accompanied  by  two  Indians,  in  June, 
1642.  An  account  of  this  has  been  preserved  by  Winthrop,  from  which 
it  appears  that  "within  12  miles  of  the  top  was  neither  tree  nor  grass, 
but  low  savins,  which  they  went  upon  the  top  of  sometimes,  but  a  con 
tinual  ascent  upon  rocks,  on  a  ridge  between  two  valleys  filled  with  snow, 
out  of  which  came  two  branches  of  Saco  river,  which  met  at  the  foot  of 
the  hill,  where  was  an  Indian  town  of  some  200  people.  *  *  *  By  the 
way,  among  the  rocks,  there  were  two  ponds, — one  a  blackish  water,  the 
other  a  reddish.  The  top  of  all  was  plain,  about  60  feet  square.  On 


6O  PHYSICAL    GEOGRAPHY. 

the  north  side  was  such  a  precipice  as  they  could  scarce  discern  to 
the  bottom.  They  had  neither  cloud  nor  wind  on  the  top,  and  moderate 
heat.  *  *  *  About  a  month  after  he  went  again,  with  five  or  six  in 
his  company."*  The  appearance  of  the  mountains  is  thus  seen  to  have 
been  the  same  two  hundred  years  ago  as  now ;  but  besides  this  descrip 
tion,  Field  brought  back  a  glowing  account  of  precious  stones,  &c.,  and 
even  of  sheets  of  "  Muscovy  glass,"  or  mica,  forty  feet  long !  The  enumer 
ation  of  these  wonders  was  probably  employed  to  collect  the  party  for  his 
second  expedition. 

This  inducement,  also,  says  the  historian,  "  caused  divers  others  to 
travel  thither,  but  they  found  nothing  worth  their  pains."  Of  these  are 
particularly  mentioned  Thomas  Gorges  and  Mr.  Vines,  two  magistrates 
of  the  province  of  Sir  Ferdinando  Gorges,  who  went  about  the  end  of 
August  of  the  same  year.  "  They  went  up  Saco  River  in  birch  canoes, 
and  that  way  they  found  it  90  miles  to  Pegwaggett,  an  Indian  town; 
but  by  land  it  is  but  60.  Upon  Saco  River  they  found  many  thousand 
acres  of  rich  meadow;  but  there  are  10  falls,  which  hinder  boats,  &c. 
From  the  Indian  town  they  went  up  hill  (for  the  most  part)  about  30 
miles  in  woody  lands.  They  then  went  about  7  or  8  miles  upon  shattered 
rocks,  without  tree  or  grass,  very  steep  all  the  way.  At  the  top  is  a 
plain  about  3  or  4  miles  over,  all  shattered  stones  ;  and  upon  that  is 
another  rock  or  spire,  about  a  mile  in  height,  and  about  an  acre  of  ground 
at  the  top.  At  the  top  of  the  plain  arise  four  great  rivers  ;  each  of  them 
so  much  water  at  the  first  issue  as  would  drive  a  mill :  Connecticut 
River  from  two  heads  at  the  N.  W.  and  S.  W.,  which  join  in  one  about 
60  miles  off ;  Saco  River  on  the  S.  E. ;  Amascoggin,  which  runs  into 
Casco  Bay,  at  the  N.  E. ;  and  Kennebeck  at  the  N.  by  E.  The  moun 
tain  runs  E.  and  W.  thirty  miles,  but  the  peak  is  above  all  the  rest. 
They  went  and  returned  in  1 5  days."  f 

The  route  taken  by  Field,  and  probably -by  the  other  explorers  also, 
lay  from  the  Saco  up  Ellis  river  nearly  to  its  source,  and  thence  up  the 
great  ridge  south-east  of  Mt.  Washington,  known  as  Boott's  Spur. 
Tuckerman's  ravine  and  Oakes's  gulf,  on  either  hand,  are  recognized  as 
the  "two  valleys  filled  with  snow."  The  summit  of  this  spur  brought

them  to  the  broadest  portion  of  the  comparatively  level  tract  at  the 
southern  base  of  Mt.  Washington,  the  south-eastern  part  of  which  is 
the  grassy  expanse  of  some  forty  acres,  known  as  Bigelow's  Lawn. 
Between  this  and  the  summit  they  encountered  the  Lake  of  the  Clouds, 
and  smaller  ponds,  which  no  doubt  furnished  Gorges  with  a  part  of  the 
sources  of  his  rivers  ;  and  no  one  who  has  looked  into  the  abyss  some 
what  absurdly  denominated  the  "  Gulf  of  Mexico,"  will  wonder  at  its 
notice  in  the  brief  account  of  the  first  explorer.  E.  Tuckerman,  in  1843, 
endeavored  to  trace  the  path  of  these  earliest  ascents,  and  was  surprised 
with  a  view  of  Mt.  Washington  as  a  somewhat  regular  pyramid  rising 
from  an  apparent  plain,  which  is  the  way  it  was  described  by  Gorges,  and 
afterwards  by  Josselyn.  Davis's  bridle-path,  opened  in  1845,  traversed  the 
bold  part  of  this  ridge,  and  afforded  the  same  view  while  it  was  in  use. 

The  first  mention  of  the  White  Mountains  in  print  occurs  in  John 
Josselyn's  "New  England's  Rarities  Discovered,"  which  was  published  in 
1672,  containing  the  earliest  notice  of  the  botany  of  the  country.  The 
materials  for  this  and  a  subsequent  work  were  collected  by  the  author 
during  two  visits  to  New  England,  coming  first  in  1638  and  remaining 
fifteen  months,  and  again  in  1663,  remaining  eight  years.  In  his  account 
of  the  mountains,  he  describes  a  pond  upon  the  highest  summit, — either 
from  a  defect  of  memory,  or  because  he  was  satisfied  with  seeing  them 
at  a  distance,  without  making  the  ascent,  and  mistook  its  position,  as 
described  by  explorers.  "Four-score  miles,"  says  Josselyn,  "to  the  North 
west  of  Scarborozv,  a  Ridge  of  Mountains  runs  North-west  and  North-east 
an  hundred  leagues,  known  by  the  name  of  the  White  Mountains,  upon 
which  lieth  snow  all  the  year,  and  is  a  Landmark  twenty  miles  off  at  Sea. 
It  is  rising  ground  from  the  seashore  to  these  Hills,  and  they  are  inacces 
sible  except  by  the  Gullies  which  the  dissolved  Snow  hath  made.  In  these 
Gullies  grow  Saven  bushes,  which,  being  taken  hold  of,  are  a  good  help 
to  the  climbing  discoverer.  Upon  the  top  of  the  highest  of  these  Moun 
tains  is  a  large  Level  or  Plain,  of  a  day's  journey  over,  whereon  nothing 
grows  but  Moss.  At  the  farther  end  of  this  Plain  is  another  Hill  called 
the  Sugarloaf,  to  outward  appearance  a  rude  heap  of  massie  stones  piled 
one  upon  another ;  and  you  may,  as  you  ascend,  step  from  one  stone  to 
another  as  if  you  were  going  up  a  pair  of  stairs,  but  winding  still  about 
the  Hill  till  you  come  to  the  top,  which  will  require  half  a  day's  time,— 


62  PHYSICAL    GEOGRAPHY. 

and  yet  it  is  not  above  a  Mile, — where  there  is  also  a  Level  of  about 
an  Acre  of  ground,  with  a  pond  of  clear  water  in  the  midst  of  it,  which 
you  may  hear  run  down,  but  how  it  ascends  is  a  mystery.  From  this 
rocky  Hill  you  may  see  the  whole  country  round  about.  It  is  far  above 
the  lower  clouds ;  and  from  hence  we  beheld  a  Vapour  (like  a  great  Pillar) 
drawn  up  by  the  Sun  Beams  out  of  a  great  Lake  or  Pond  into  the  air, 
where  it  was  formed  into  a  Cloud.  The  Country  beyond  these  Hills 
Northward  is  daunting  terrible,  being  full  of  rocky  Hills  as  thick  as  Mole 
hills  in  a  Meadow,  and  cloathed  with  infinite  thick  Woods."*  In  his 
"Voyages,"  published  a  year  or  two  later,  Josselyn  corrects  what  he  says 
of  the  snow's  lying  the  whole  year  upon  the  mountains,  by  excepting  the 
month  of  August,  f 

The  "Voyages"  contain  an  account  of  the  Indian  traditions  which 
clustered  about  our  highest  mountains.  "Ask  them,"  says  Josselyn, 
"whither  they  go  when  they  dye,  they  will  tell  you,  pointing  with  their 
finger  to  Heaven,  beyond  the  White  Mountains ;  and  do  hint  at  Noah's 
Floud,  as  may  be  conceived  by  a  story  they  have  received  from  Father  to 
Son,  time  out  of  mind,  that  a  great  while  agon  their  Countrey  was 
drowned,  and  all  the  People  and  other  Creatures  in  it,  only  one  Powaw 
and  his  Webb,  foreseeing  the  Floud,  fled  to  the  White  Mountains,  carrying 
a  hare  along  with  them,  and  so  escaped.  After  a  while,  the  Powaw  sent 
the  Hare  away,  who  not  returning,  emboldened  thereby,  they  descended, 
and  lived  many  years  after  and  had  many  children,  from  whom  the  Coun- 
trie  was  again  filled  with  Indians."  \  None  of  the  traditions  of  the 
native  tribes  appear  to  have  been  so  widespread  as  that  of  a  flood ;  and 
many  notices  might  be  cited  similar  to  this  of  the  White  Mountains. 
Catlin  describes  a  ceremony  referring  to  this  which  he  witnessed  among 
the  Mandans,  on  the  upper  Missouri  river,  where  the  only  survivor  was 
represented  as  white. 

The  next  mention  of  explorations  among  the  White  Mountains  is  on 
April  29,  1725,  when  "a  ranging  company  ascended  the  highest  mountain 
on  the  N.  W.  part," — probably  the  first  ascent  from  this  side.  As  was  to 
be  expected,  they  found  the  snow  deep  and  the  Alpine  ponds  frozen.  ||

Mountains,  on  a  warm  day  in  the  Month  of  March,  in  1 746,  were  alarmed 
with  a  repeated  noise,  which  they  supposed  to  be  the  firing  of  guns.  On 
further  search,  they  found  it  to  be  caused  by  rocks  falling  from  the  south 
side  of  a  steep  mountain."*  This  is  the  first  notice  that  we  find  of  the 
mighty  force  that  has  left  its  furrows  and  scars  all  through  the  mountains, 
and  which  caused  to  be  written  the  saddest  page  in  their  history. 

DISCOVERY  OF  THE  WHITE  MOUNTAIN  NOTCH. 

It  is  supposed  that  the  Indians  were  aware  of  the  central  pass  through 
the  White  Mountains,  and  took  their  captives  through  it  to  Canada ;  but 
its  existence  was  unknown  to  the  English  at  the  time  of  the  first  settle 
ments  of  the  Coos  country.  The  value  of  these  lands  was  thus  very 
much  diminished  on  account  of  the  wide  circuit  which  must  be  made 
either  to  east  or  west  to  communicate  with  the  seaboard,  so  that  it 
became  a  matter  of  inquiry  to  the  authorities  of  the  state  how  a  way 
should  be  opened  through  this  almost  impassable  chain.  Its  discovery 
was  made  in  1771  by  one  Timothy  Nash,  a  pioneer  hunter  who  had 
established  himself  in  this  solitary  region.  Climbing  a  tree  on  Cherry 
mountain  in  search  of  a  moose,  he  discovered,  as  he  thought,  the  wished- 
for  pass.  Steering  for  the  opening,  he  soon  struck  the  Saco  river,  a  mere 
brook,  and,  following  down,  stopped  at  what  is  now  known  as  the  gate 
of  the  notch.  Here  the  sharp  rocks  came  so  near  together  as  to  prevent 
his  following  the  stream  ;  but,  seeing  that  by  a  reasonable  expenditure 
a  road  could  be  opened  at  the  point,  he  scaled  the  cliffs  and  continued 
on  to  Portsmouth.  Here  he  made  known  his  discovery  to  Governor 
Wentworth.  The  wary  governor,  to  test  the  practicability  of  the  pass, 
informed  Nash  that  if  he  would  bring  him  a  horse  down  through  the 
gorge  from  Lancaster,  he  would  grant  him  the  tract  of  land  now  known 
as'  Nash  and  Sawyer's  location.  To  accomplish  this,  Nash  admitted 
a  fellow  hunter,  Benjamin  Sawyer,  to  a  share  in  his  trade.  By  means 
of  ropes  they  succeeded  in  getting  the  horse  over  the  projecting  cliff 
and  down  the  rugged  pathway  of  the  mountain  torrent,  and  brought 
him  to  the  governor.  When  they  saw  the  horse  safely  lowered  on  the 
south  side  of  the  last  projection,  it  is  said  that  Sawyer,  draining  the  last

64  PHYSICAL    GEOGRAPHY. 

drop  of  rum  from  his  junk  bottle,  and  breaking  it  on  the  rock,  called  it 
Sawyer's  rock,  by  which  name  it  has  ever  since  been  known.  A  road 
was  soon  opened  by  the  proprietors  of  lands  in  the  upper  Coos,  and 
settlers  began  to  make  their  way  into  the  immediate  vicinity  of  the 
mountains.  Jefferson,  Whitefield,  Littleton,  and  Franconia  were  first 
settled  within  two  or  three  years  after  this  date.  A  road  was  also  com 
menced  through  the  eastern,  or  Pinkham  notch,  in  1 774,  and  Shelburne, 
which  included  Gorham,  received  its  first  inhabitants  in  the  following  year. 
The  earliest  articles  of  commerce  taken  through  the  notch  have  not 
escaped  mention.  They  appear  to  have  been  a  barrel  of  tobacco,  raised 
at  Lancaster,  which  was  carried  to  Portsmouth,  and  a  barrel  of  rum 
which  a  company  in  Portland  offered  to  any  one  who  should  succeed  in 
taking  it  through  the  pass.  This  was  done  by  Captain  Rosebrook,  with 
some  assistance,  though  it  was  nearly  empty,  we  are  informed,  "through 
the  politeness  of  those  who  helped  to  manage  the  affair."  The  difficulty 
of  communication  was  often  the  occasion  of  more  serious  want,  and  it 
was  no  rare  thing  to  suffer  from  scarcity  of  provisions.  In  1800,  the 
inhabitants  of  Bethlehem  were  obliged  to  leave  their  occupations,  go 
into  the  woods,  and  cut  and  burn  timber  enough  for  a  load  of  potash,  with 
which  to  procure  provisions  after  a  journey  of  one  hundred  and  seventy 
miles.  The  tenth  turnpike  of  New  Hampshire  was  incorporated  in  1803, 
to  extend  from  the  west  line  of  Bartlett,  through  the  White  Mountain 
notch,  a  distance  of  twenty  miles.  The  original  cost  of  the  road  was 
forty  thousand  dollars,  and  the  expense  of  repairs  was  large ;  but  it  proved 
a  profitable  investment.  Strings  of  teams  of  half  a  mile  in  length  were 
sometimes  seen  winding  through  Conway  on  their  route  to  Portland,  the 
great  market  at  that  time  for  all  northern  New  Hampshire. 

VISITS  OF  SCIENTIFIC  PARTIES. 

Mt.  Washington  was  ascended  in  July,  1784,  "with  a  view  to  make 
particular  observations  on  the  several  phenomena  which  might  occur," 
the  party  consisting  of  the  Rev.  Manasseh  Cutler,  of  Ipswich,  Mass.,  a 
zealous  member  of  the  American  Academy  of  Arts  and  Sciences,  the 
Rev.  Daniel  Little,  of  Kcnnebunk,  Me.,  also  a  member  of  the  Academy, 
and  Col.  John  Whipple,  of  Jefferson  (then  Dartmouth),  together  with 
others  to  the  number  of  seven  in  all.  They  are  said  to  have  been  "the 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  65 

subject  of  much  speculation"  as  they  passed  through  Eaton  and  Conway. 
Dr.  Belknap,  the  early  historian  of  the  state,  and  Dr.  Fisher,  of  Beverly, 
Mass.,  were  of  this  party,  but  neither  of  them  succeeded  in  reaching  the 
summit.  Dr.  Fisher  remained  at  the  notch  "to  collect  birds,  and  other 
animal  and  vegetable  productions."  The  objects  of  the  expedition  were 
but  partially  attained.  It  happened  unfortunately  that  thick  clouds 
covered  the  mountains  nearly  the  whole  time,  so  that  the  instruments, 
which  they  had  carried  up  with  much  labor,  were  rendered  useless.  They 
made  some  unsatisfactory  barometrical  observations,  but  were  unable  to 
test  them  in  an  attempted  geometrical  measurement  from  the  base. 
The  barometer  had  suffered  so  much  agitation  that  an  allowance  was 
necessary,  and  the  altitude  was  computed  in  round  numbers  at  5,500  feet 
above  the  meadow  in  the  valley  below,  and  nearly  10,000  feet  above  the 
level  of  the  sea.  This  was  no  greater  altitude  than  appears  to  have  been 
generally  assigned  to  these  mountains.  Dr.  Belknap,  in  1792,  gave  his 
opinion  that  these  figures  were  too  small,  predicting  "that  whenever  the 
mountain  can  be  measured  with  the  requisite  precision,  it  will  be  found 
to  exceed  ten  thousand  feet,  of  perpendicular  altitude,  above  the  level  of 
the  ocean."* 

The  plants  of  the  upper  region  were  now  described  for  the  first  time, 
but  only  in  a  general  way.  The  following  extract  from  a  manuscript  of 
Dr.  Cutler,  which  is  quoted  by  Belknap,  points  out  the  more  prominent 
botanical  features,  as  seen  by  the  first  scientific  party:  "There  is  evi 
dently  the  appearance  of  three  zones, —  I,  the  woods;  2,  the  bald,  mossy 
part;  3,  the  part  above  vegetation.  The  same  appearance  has  been 
observed  on  the  Alps  and  all  other  high  mountains.  I  recollect  no  grass 
on  the  plain.  The  spaces  between  the  rocks  in  the  second  zone  and  on 
the  plain  are  filled  with  spruce  and  fir,  which  perhaps  have  been  growing 
ever  since  the  creation,  and  yet  many  of  them  have  not  attained  a  greater 
height  than  three  or  four  inches  ;  but  their  spreading  tops  are  so  thick  and 
strong  as  to  support  the  weight  of  a  man  without  yielding  in  the  smallest 
degree ; — the  snows  and  winds  keeping  the  surface  even  with  the  general 
surface  of  the  rocks.  In  many  places  on  the  sides  we  could  get  glades  of 
this  growth  some  rods  in  extent,  when  we  could,  by  sitting  down  on  our

feet,  slide  the  whole  length.  The  tops  of  the  growth  of  wood  were  so 
thick  and  firm  as  to  bear  us  currently  a  considerable  distance  before  we 
arrived  at  the  utmost  boundaries,  which  were  almost  as  well  defined  as 
the  water  on  the  shore  of  a  pond.  The  tops  of  the  wood  had  the  appear 
ance  of  having  been  shorn  off,  exhibiting  a  smooth  surface  from  their 
upper  limits  for  a  great  distance  down  the  mountain."  "  On  the  upper 
most  rock"  the  letters  "N.  H."  were  engraved  ;  and  a  plate  of  lead  bearing 
the  names  of  the  party  was  deposited  under  a  stone. 

The  route  by  which  Cutler  and  his  party  reached  the  mountain  is  prob 
ably  indicated  by  the  stream  which  bears  his  name  in  Bigelow's  narrative. 
"In  less  than  half  a  mile  southward  from  this  fountain," — that  is,  of  Ellis 
river,  at  the  height  of  land  between  the  Saco  and  the  Androscoggin,  in 
Pinkham  woods, — "a  large  stream,  which  runs  down  the  highest  of  the 
White  Mountains,  falls  into  Ellis  river ;  and,  in  about  the  same  distance 
from  this,  another  falls  from  the  same  mountain.  The  former  of  these 
streams  is  Cutler's  river,  the  latter  New  river."  This  name  is  said  to 
have  been  applied  to  the  stream  at  Dr.  Cutler's  express  wish. 

A  "Second  Scientific  Visit"  was  made  in  1804  by  Dr.  Cutler,  who  was 
accompanied  by  W.  D.  Peck,  afterwards  professor  of  natural  history  at 
Cambridge,  Mass.  Barometrical  observations  made  on  this  occasion,  and 
computed  by  Mr.  Bowditch,  gave  to  Mt.  Washington  an  elevation  of  7,05  5 
feet  above  the  sea.  A  collection  of  the  Alpine  plants  was  made  by  Dr. 
Peck,  and  was  afterwards  seen  by  Mr.  Pursh,  in  whose  "  Flora  of  North 
America,"  printed  in  1814,  many  of  the  most  interesting  species  were 
described.  Naturalists  soon  began  to  give  special  attention  to  the 
peculiar  Arctic  flora  and  fauna  of  these  mountains.  A  quite  complete 
enumeration  and  description  of  the  phsenogamous  plants,  together  with  a 
statement  of  much  concerning  their  mineralogy  and  zoology  appeared  in 
Dr.  Bigelow's  "Account  of  the  White  Mountains  of  New  Hampshire," 
published  in  1816,  from  explorations  made  during  the  same  season.  Dr. 
Francis  Boott,  Mr.  Francis  C.  Gray,  and  the  venerable  Chief  Justice  Shaw 
were  members  of  this  party.  The  barometrical  observations  which  they 
obtained  gave  6,225  feet  above  the  sea.  This  visit  was  made  in  June ;  and 
Dr.  Boott  made  a  second  visit  the  succeeding  month,  adding  a  considera 
ble  number  of  species  to  the  botanical  collections.  The  ascent  was  from 
the  eastern  pass,  following  Cutler's  river.  In  1 8 1 9,  Abel  Crawford  opened 


EXPLORATIONS    AMONG   THE    WHITE    MOUNTAINS.  6/ 

a  footway  to  Mt.  Washington,  following  the  south-western  ridge.  This, 
and  the  new  road  made  two  years  later  by  Ethan  Allen  Crawford  along 
the  Ammonoosuc,  subsequently  became  the  more  common  ways  of 
ascending  the  mountains.  Botanists  were  gainers  by  this  change, 
especially  those  whose  work  was  carried  on  without  camping  out,  as 
these  routes  enabled  them  to  examine  the  finest  localities  for  Alpine 
plants  while  on  their  way  to  the  summit.  An  account  of  the  expedition 
of  1 8 1 6  appeared  in  the  New  England  Journal  of  Medicine  and  Surgery 
for  November  of  the  same  year. 

MAPS,  SURVEYS,  AND  NAMES. 

The  first  and  only  map  of  New  Hampshire  issued  under  the  direction 
of  the  state  authorities,  was  that  of  Philip  Carrigain,  published  in  i8id 
The  author's  name  is  still  preserved  at  the  White  Mountains,  as  that  of 
the  noblest  of  the  peaks  upon  the  east  branch  of  the  Pemigewasset, — too 
distant,  however,  from  settlements  to  be  often  visited  by  tourists.  This 
map  notices  that  recent  barometrical  calculations  give  7,162  feet  above  the 
sea  as  the  height  of  the  White  Mountains ;  and  states  that,  being  below 
the  line  of  perpetual  congelation,  which  must  be  7,200  feet  lower  than  in 
Europe  on  the  same  parallel,  they  cannot  exceed  7,800  feet.  The  author 
then  somewhat  incorrectly  adds, — "After  every  abridgment  of  the  here 
tofore  exaggerated  estimates  of  their  altitude,  it  will  be  found  doubly  to 
exceed  that  of  any  mountain  in  the  United  States  other  than  those  of 
New  Hampshire."  The  Franconia  and  Mt.  Washington  ranges,  with 
intervening  ranges  and  peaks,  are  laid  down  on  this  map ;  but  no  names 
are  applied  to  individual  summits  throughout  this  central  area  of  the 
White  Mountains,  with  the  exception  of  Lafayette,  which  is  called 
"Great  Haystack."  The  prominent  mountains  which  stand  on  guard 
just  outside  this  area,  however,  were  already  distinguished  by  the  same 
names  as  now.  We  find  "Pigwacket  Mt.,  formerly  Kiarsarge;"  "Corway 
Peak  Mt."  (Chocorua);  also,  "Corway"  pond  and  river;  and,  on  the  west, 
Kinsman's  Mt.  and  "Moosehillock"  Mt.  The  latter  is  in  the  town  of 
"Coventry,"  changed  to  Benton  in  1840.  Albany,  Woodstock,  Carroll, 
Randolph,  and  Jackson  are  designated  by  the  names  Burton,  Peeling, 
Breton  Woods,  Durand,  and  Adams,  The  name  of  "  Merrimack  River,  or 
Pemigewasset  Br.,"  is  applied  to  that  stream  above  Franklin ;  while  the 


68

East  Branch  is  marked  "  Merrimack  R."  The  names  Hancock  Br.  and 
"Moosfhillock"  Br.,  and  the  old  form  Ammariscoggin,  are  also  found  on 
this  map.  In  his  short  notice  of  the  productions  and  natural  features 
of  the  state,  the  author  remarks,  referring  to  its  lake  and  mountain 
scenery,  "  It  may  be  called  the  Switzerland  of  America," — a  term  which 
has  been  generally  adopted  in  descriptions  of  New  Hampshire. 

The  first  carefully  prepared  map  of  the  White  Mountains  was  published 
by  Prof.  G.  P.  Bond,  of  Cambridge,  Mass.,  in  1853,  from  original  triangu- 
lation.  The  history  of  the  efforts  of  the  geological  survey  to  secure 
more  perfect  maps  of  this  region,  with  the  result  of  these  labors,  is  given 
in  another  part  of  this  work.

Considerable  interest  appears  to  have  been  awakened  as  to  the  altitude 
of  these  mountains,  on  account  of  the  conflicting  results  of  barometrical 
measurements;  and  we  find  that  in  July,  1820,  a  party  of  engineers  and 
others  from  Lancaster  visited  the  whole  range  between  the  notch  and 
Mt.  Madison,  and,  on  a  second  visit,  measured  the  altitudes  with  a  spirit

level.  The  first  party  consisted  of  Adino  N.  Brackett,  John  W.  Weeks, 
Gen.  John  Wilson,  Charles  J.  Stuart,  Noyes  S.  Dennison,  and  Samuel  A. 
Pearson,  of  Lancaster,  with  Philip  Carrigain  and  E.  A.  Crawford,  the 
latter  acting  as  pilot  and  baggage-carrier.  This  party  gave  names  to  Mts. 
Pleasant,  Franklin,  Monroe,  Jefferson,  Adams,  and  Madison.  They  called 
the  Lake  of  the  Clouds  "Blue  pond;"  and  the  locality  since  named  after 
Bigelow  was  by  them  called  "  Carrigain's  lawn."  The  dead,  gnarled  trees, 
which  are  especially  conspicuous  on  Moosilauke  and  common  on  all  the 
mountains,  received  special  notice.  They  were  called  by  some  members 
of  the  party  buck's  horns,  and  by  others  bleached  bones.  The  cause  of  the 
death  of  these  trees  they  supposed  to  have  been  the  cold  seasons  which 
prevailed  from  1812  to  1816,  saying, — "It  can  hardly  be  doubted  that 
during  the  whole  of  the  year  1816  these  trees  continued  frozen."  This 
was  the  year  long  remembered  as  the  "year  without  a  summer."  About 
a  month  after  this  visit,  Weeks,  Stuart,  and  Brackett,  accompanied  by 
Richard  Eastman,  spent  seven  days  in  levelling  to  the  tops  of  all  these 
mountains  from  Lancaster,  encamping  on  them  four  nights ; — that  of 
August  3ist  on  the  summit  of  Mt.  Washington.  They  must  have  been 
the  first  party  who  ever  spent  the  night  upon  the  summit.  They  made 
Mt.  Washington  6,428  feet  above  the  sea,  or  5,850  feet  above  the  river  at 
Lancaster.  An  interesting  account  of  these  visits  is  found  in  the  "  New 
Hampshire  Historical  Collections"  for  1823.  During  the  year  following 
these  visits,  Capt.  Partridge  again  computed  the  height  of  Mt.  Washing 
ton  from  barometrical  observations,  giving  6,234  ^ee^  The  observations 
of  Dr.  C.  T.  Jackson,  in  1840,  were  quite  accurate  for  the  difference  in 
height  between  Mt.  Washington  and  the  notch.  Correcting  the  error  for 
the  height  of  the  notch,  his  figures  would  stand  6,303,  instead  of  6,228, 
only  ten  feet  in  excess  of  the  correct  height.  Prof.  Arnold  Guyot,  in 
1851,  from  barometrical  observations,  gives  the  figures  of  6,291  feet.  In 
his  memoir  of  the  "Appalachian  Mountain  System,"  published  in  1861,  he 
has  altered  these  figures  to  6,288.  In  1853,  Capt.  T.  J.  Cram  levelled  to 
the  summit  of  Mt.  Washington,  under  the  direction  of  the  United  States 
Coast  Survey,  and  reported  its  height  to  be  6,293  feet,  which  may  be 
assumed  to  be  the  true  altitude. 

The  Indians  are  said  to  have  been  restrained  by  awe  and  fear  from 
climbing  to  the  summits  of  these  mountains.     Their  traditions  repre-

sented  that  here  was  the  residence  of  the  Great  Spirit,  who,  with  a 
motion  of  the  hand,  could  raise  a  storm  and  destroy  the  daring  adven 
turer  who  presumed  to  approach  his  abode.  They  never  felt,  amid  the 
sublimity  and  awfulness  of  the  mountains,  that  sense  of  ownership  and 
appropriation  which  was  inspired  by  rivers  and  lakes,  with  their  calmer 
beauty  and  life-sustaining  productiveness.  Thus,  while  solitary  mountains 
throughout  the  state,  like  nearly  all  the  rivers,  still  preserve  the  names  of 
their  ancient  baptism,  always  the  last  memorial  of  a  departed  race,  the 
central  portion  of  the  White  Mountains  is  wholly  English  in  name  and 
associations.  We  do  not  know  that  the  Indians  distinguished  them  by 
any  other  than  a  collective  name.  This,  according  to  Dr.  Belknap,  was 
AgiococJiook  in  one  dialect,  and  in  another  Waumbckkct-MctJina,  signify 
ing  Mountains  zuitk  snoivy  forcJicads,  The  English  name  White  Moun 
tains  we  meet  in  the  earliest  account  of  them  that  was  published.  It  is 
not  improbable  that  this  name  was  applied  to  them  while  as  yet  they 
were  only  known  to  adventurous  mariners  in  their  exploring  voyages 
along  the  coast. 

It  is  impossible  to  ascertain  with  certainty  who  first  proposed  to  call 
the  highest  of  these  summits  Mt.  Washington.  Dr.  Belknap,  in  1792, 
says  of  it, — "it  has  lately  been  distinguished  by  the  name  of  Mount 
Washington."  He  quotes  from  the  manuscript  of  Dr.  Cutler,  in  another 
place,  the  account  of  the  zones  of  vegetation,  where  mention  is  made  of 
"Mount  Washington"  as  if  it  were  well  known.  As  his  visit  was  made 
in  1784,  it  is  not  unlikely  that  the  name  was  proposed  soon  after  the 
close  of  the  revolutionary  war,  probably  by  Dr.  Cutler's  party.  Of  other 
prominent  peaks,  besides  those  named  by  the  party  of  1820,  Mt.  Clinton 
received  its  name  from  some  undiscoverable  source,  certainly  before  1837. 
Mts.  Clay  and  Jackson  were  named  by  Mr.  Oakes.  This  gentleman  was 
with  Prof.  Tuckerman,  and  sent  up  his  guide,  Amasa  Allen,  to  build  a 
fire  on  the  top  of  the  south  spur  of  Clinton  ;  and  thus,  with  a  fiery  bap 
tism,  the  mountain  was  christened  Jackson.  Mt.  Willard  was  named 
from  Mr.  Sidney  Willard,  of  Boston ;  and  it  is  probable  that  the  name  of 
Mt.  Webster  was  proposed  by  Mr.  Willard  for  the  peak  known  to  earlier 
visitors  as  Notch  mountain.  Lower  down  the  Saco,  Mts.  Crawford  and 
Resolution,  as  well  as  the  Giant's  stairs,  received  names  from  Dr.  S.  A. 
Bemis.  The  names  of  Tuckerman's  ravine,  Oakes's  gulf,  and  Bigelow's 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS.  *Jl 

lawn  were  given,  in  honor  of  three  eminent  botanists  who  had  particu 
larly  distinguished  themselves  in  the  study  of  the  White  Mountain  flora, 
to  three  fine  localities  of  plants  as  well  as  marked  topographical  features. 
It  is  difficult  to  ascertain  the  origin  of  many  of  the  names  of  natural 
objects  about  the  mountains.  Dr.  Bemis  has  perhaps  applied  more 
appellations  than  any  other  person  to  these  features.  Other  names 
have  been  given  by  chance  visitors,  and  preserved  by  usage  among 
guides. 

No  Indian  legends  remain  about  the  mountains,  and  but  few  localities 
have  a  particular  history.  There  is  one  cascade,  however,  about  a  quarter 
of  a  mile  from  the  former  residence  of  old  Abel  Crawford,  which  is  more 
distinguished  by  the  sad  story  associated  with  it,  than  by  the  picturesque- 
ness  of  the  crags  through  which  it  hurries  for  the  last  mile  of  its  descent. 
It  is  called  "Nancy's  brook."  Here,  late  in  the  autumn  of  i/SS,  a  young 
woman,  who  had  lived  with  a  family  in  Jefferson,  was  found  frozen  to  death. 
She  was  engaged  to  be  married  to  a  man  who  was  employed  in  the  same 
family  where  she  served,  and  had  entrusted  to  him  all  her  earnings,  with 
the  understanding  that  in  a  few  days  they  should  leave  for  Portsmouth 
to  be  married  there.  During  her  temporary  absence  at  Lancaster,  nine 
miles  distant,  the  man  started  with  his  employer  for  Portsmouth,  leaving 
no  explanation  or  message  for  her.  She  learned  the  fact  of  her  deser 
tion  on  the  same  day,  and  at  once  walked  back  to  Jefferson,  tied  up  a 
small  bundle  of  clothing,  and,  in  spite  of  all  warnings  and  entreaties, 
set  out  on  foot  to  overtake  them.  The  distance  to  the  notch  was  thirty 
miles,  with  no  settlement  on  the  way,  the  only  road  being  a  hunter's  path 
marked  by  spotted  trees.  It  had  been  snowing,  but  she  pressed  on  over 
this  road  through  the  night,  in  the  hope  of  overtaking  her  lover  at  the 
camp  in  the  notch  before  the  party  should  start  in  the  morning.  She 
reached  it  soon  after  they  had  left,  and  it  appeared  to  those  who,  alarmed 
for  her  safety,  had  followed  on  from  Jefferson  to  overtake  her,  that  she 
had  tried  in  vain  to  rekindle  the  fire  in  the  lonely  camp.  Failing  in  this, 
she  had  hurried  on,  climbing  the  wild  pass  of  the  notch,  and  following 
the  track  of  the  Saco  towards  Conway.  Several  miles  of  the  roughest 
part  of  the  way  she  travelled  thus,  often  fording  the  river.  But  her 
strength  was  spent  by  two  or  three  hours  of  such  toil ;  and  she  was 
found  by  the  party  in  pursuit  of  her,  chilled  and  stiff  in  the  snow,  at  the

foot  of  an  aged  tree  near  "  Nancy's  bridge,"  not  many  hours  after  she 
had  ceased  to  breathe. 

EARLY  SETTLEMENTS. 

President  Dwight,  of  Yale  college,  visited  the  notch  in  1797,  and 
again  in  1803,  and  has  left  in  his  "Travels"  an  appreciative  description  of 
the  White  Mountain  scenery,  besides  some  account  of  the  early  settlers 
of  this  region.  The  two  prominent  names  are  those  of  Eleazer  Rose- 
brook  and  Abel  Crawford.  Mr.  Rosebrook  was  a  pioneer  from  Grafton, 
Mass.,  whence  he  removed  to  Lancaster  about  1 772  ;  he  finally  settled  at 
Monadnock,  now  Colebrook.  Here  he  was  fully  thirty  miles  from  any 
inhabitant,  with  no  path  to  his  cabin  excepting  blazed  trees.  During  the 
revolutionary  war  he  removed  to  Guildhall,  Vt,  in  order  to  place  his 
family  in  the  neighborhood  of  settlements,  being  absent  from  them  most 
of  the  time  in  the  military  service  of  the  frontier.  In  1792,  he  sold  his 
fine  farm  on  the  Connecticut,  and  once  more  sought  the  wilderness, — 
removing,  in  the  depth  of  winter,  to  Nash  &  Sawyer's  location.  Here  he 
soon  built  a  large  two-story  house,  at  the  base  of  what  was  known  as  the 
Giant's  grave,  occupying  nearly  the  same  site  as  the  present  Fabyan 
house.  He  also  built  a  saw-mill  and  grist-mill,  and  large  barns,  stables,

EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  73 

and  sheds.  He  had  hardly  become  comfortably  situated,  however,  when 
a  cancer  broke  out  on  his  lip,  and  after  a  few  years  of  intense  suffering, 
which  was  patiently  borne,  he  died  September  2/th,  1817.  "In  all 
respects  Mr.  Rosebrook  was  a  remarkable  man.  He  loved  the  rugged 
scenes  of  pioneer  life,  and  was  never  more  in  his  element  than  while 
scaling  the  mountain,  or  trapping  the  wolf  or  bear.  There  are  men 
enough  who  prefer  the  city,  and  cling  fondly  around  their  native  village  ; 
but  he  could  never  endure  the  restraints  connected  with  our  larger  settle 
ments, — the  restraints  of  artificial  life ;  but  freely,  his  arms  and  broad 
chest  all  bare,  he  must  breathe  the  strong,  pure  air,  as  it  came  rushing 
along  through  these  mountain  gorges." 

Abel  Crawford,  who  married  Capt.  Rosebrook's  daughter,  and  who  is 
remembered  as  the  "patriarch  of  the  mountains,"  also  came  from  Guild 
hall  a  few  years  later,  locating  himself  twelve  miles  farther  south,  near 
the  site  of  the  present  Mt.  Crawford  house.  In  1840,  at  the  age  of 
seventy-five,  he  made  the  first  horseback  ascent  to  the  top  of  Mt.  Wash 
ington.  Dr.  C.  T.  Jackson,  state  geologist,  was  a  member  of  the  same 
party.  Mr.  Crawford  died  at  the  advanced  age  of  eighty-five.  For  sixty 
years  he  had  been  acquainted  with  this  region,  and  had  seen  the  gradual 
process  of  civilization  applied  to  the  wilderness  from  upper  Bartlett  to 
Bethlehem.  So  long  had  he  been  accustomed  to  travellers  during  the 
summer  months,  that  he  felt  he  could  not  die  without  seeing  them  arrive 
once  more.  "  He  used  to  sit,  in  the  warm  spring  days,  supported  by  his 
daughter,  his  snow-white  hair  falling  to  his  shoulders,  waiting  for  the  first 
ripple  of  that  large  tide  which  he  had  seen  increasing  in  volume  for 
twenty  years.  Not  long  after  the  stages  began  to  carry  their  summer 
freight  by  his  door,  he  passed  away." 

His  son,  Ethan  Allen  Crawford,  succeeded  to  the  estate  of  Capt.  Rose- 
brook  ;  but  the  ample  buildings  which  the  latter  had  reared  were  soon  after 
burned  to  the  ground.  For  many  years  the  Crawfords  were  the  only  ones 
to  entertain  strangers  at  the  mountains.  All  the  bridle-paths  on  the  west 
side  were  cut  by  them,  the  first  of  which,  made  for  a  foot-path  in  1821, 
extended  from  the  Rosebrook  place,  nearly  seven  miles,  to  the  foot  of  Mt. 
Washington,  following  the  Ammonoosuc  river.  It  was  afterwards  known 
as  "  Fabyan's  road."  It  was  in  this  year  that  ladies  first  climbed  to  the 
summit.  They  were  three  in  number, — sisters, — the  Misses  Austin,  of

Portsmouth.  With  a  firm  determination  to  obtain  a  fine  prospect,  they 
remained  four  days  near  the  top  in  a  small  stone  cabin,  until  the  weather 
became  propitious.  With  the  beginning  of  the  present  century,  visitors 
to  the  White  Mountains  increased  in  number.  In  1819,  the  number 
averaged  ten  or  twelve  annually ;  and  the  pioneer  settlers  began  to  pro 
vide  means  for  their  accommodation.  Abel  Crawford  and  his  sons  were 
the  efficient  guides  of  the  early  visitors ;  and  many  traditions  are  still 
current  of  their  skill  and  strength,  both  as  guides  and  hunters.  They 
were  all  of  the  largest  stature;  and  Ethan  Allen,  known  as  the  "giant  of 
the  mountains,"  was  nearly  seven  feet  in  height.  With  additional  facili 
ties,  the  number  of  visitors  gradually  increased,  so  that  in  1858  it  was 
estimated  that  five  thousand  annually  ascended  the  various  bridle-paths. 
In  1870,  the  number  was  estimated  at  seven  thousand,  of  whom  five 
thousand  registered  their  names  at  the  Tip-top  house. 

Of  all  the  adventurous  lives  which  have  been  passed  among  the 
shadows  of  these  mountains,  perhaps  none  exceeds,  in  thrilling  interest 
and  remarkable  contrasts,  that  of  Ethan  Allen  Crawford,  whom  we  have 
already  had  occasion  several  times  to  mention.  A  considerable  "  History 
of  the  White  Mountains,"  with  his  experiences  and  reminiscences,  has 
been  left  us  by  his  own  hand.  Many  of  the  wisest  and  most  distin 
guished  of  the  country  were  entertained  under  his  rude  roof,  who  grate 
fully  remembered  his  hospitality  and  his  faithful  service  in  guiding  them 
to  the  great  ridge.  He  would  come  home  from  a  bear-fight  to  find  in  his 
house,  perhaps,  "a  member  of  congress,  Daniel  Webster,"  who  desired  his 
assistance  on  foot  to  the  summit  of  Mt.  Washington.  Ethan  says  that 
they  went  up  "without  meeting  anything  worthy  of  note,  more  than  was 
common  for  me  to  find ;  but  to  him  things  appeared  interesting:  And 
when  we  arrived  there  he  addressed  himself  in  this  way,  saying, — 'Mt. 
Washington,  I  have  come  a  long  distance,  and  have  toiled  hard  to  arrive 
at  your  summit,  and  now  you  give  me  a  cold  reception.  I  am  extremely 
sorry  that  I  shall  not  have  time  enough  to  view  this  grand  prospect  which 
lies  before  me ;  and  nothing  prevents  but  the  uncomfortable  atmosphere 
in  which  you  reside.'"  The  snow  from  a  sudden  squall  froze  upon  them 
as  they  descended.  The  statesman  had  evidently  become  interested  in 
his  guide,  for  Ethan  adds  that  "the  next  morning,  after  paying  his  bill,  he 
made  me  a  handsome  present  of  twenty  dollars." 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS.  75 

The  fire  which  destroyed  his  buildings  left  him  heavily  oppressed  by 
debts,  a  burden  which  he  was  never  able  to  throw  off.  His  crops  were 
swept  away,  and  his  meadows  filled  with  sand  by  freshets.  Other  forms 
of  adversity,  too,  beset  him.  Before  middle  life,  his  own  powerful  frame 
was  so  shaken  by  disease  and  pain  that  a  flash  of  lightning,  he  would 
sometimes  say,  seemed  to  run  from  his  spine  to  the  ends  of  his  hair.  But 
the  example  of  his  wife  taught  him  how  to  meet  calamity  and  distress 
without  despair  and  repining.  He  was  put  in  jail  at  last,  in  Lancaster, 
for  debt.  She  wrote  a  pleading  letter  to  his  chief  creditor  to  release  him, 
but  without  effect.  "This,"  says  Ethan,  "forced  me,  in  the  jail,  to  reflect 
on  human  nature,  and  it  overcame  me  so  that  I  was  obliged  to  call  for  the 
advice  of  physicians  and  a  nurse."  Broken  in  health,  oppressed  by 
pecuniary  burdens,  and  with  shattered  spirits,  he  left  the  plateau  at  the 
base  of  Mr.  Washington  for  a  more  pleasant  home  in  Vermont.  But 
he  experienced  hard  fortune  there,  too,  and  returned  to  die  within  sight 
of  the  range,  an  old  man,  before  he  had  reached  the  age  of  fifty-six  years. 

"  Since  the  breaking  up  of  his  home  at  the  Giant's  grave,"  says  T.  Starr 
King,  "the  mountains  have  heard  no  music  which  they  have  echoed  so 
heartily  as  the  windings  of  his  horn,  and  the  roar  of  the  cannon  which  he 
used  to  load  to  the  muzzle,  that  his  guests  might  hear  a  park  of  artillery 
reply.  Few  men  that  have  ever  visited  the  mountains  have  done  more 
faithful  work,  or  borne  so  much  adversity  and  suffering.  The  cutting  of 
his  heel-cord  with  an  axe,  when  he  was  chopping  out  the  first  path  up  Mt. 
Washington,  was  a  type  of  the  result  to  himself  of  his  years  of  toil  in 
the  wilderness ;  and  his  own  quaint  reflection  on  that  wound,  which 
inflicted  lameness  upon  him  for  months,  is  the  most  appropriate  inscrip 
tion, — after  the  simple  words,  'an  honest  man,' — that  could  be  reared  over 
his  grave : — '  So  it  is  that  men  suffer  various  ways  in  advancing  civiliza 
tion  ;  and,  through  God,  mankind  are  indebted  to  the  labors  of  men  in 
many  different  spheres  of  life.'" 

At  about  the  same  time  with  the  settlement  of  the  Crawfords,  a 
tract  of  land  three  miles  below  the  mouth  of  the  notch  was  first 
improved  by  a  Mr.  Davies  ;  this  was  the  farm  afterwards  occupied  by 
Mr.  Willey.  In  describing  his  second  visit  to  this  place,  President 
Dwight  has  preserved  a  record  of  one  of  the  great  fires  which  have 
devastated  the  mountains  of  the  notch.  "When  we  entered  upon  this 


76  PHYSICAL    GEOGRAPHY. 

farm  in  1803,  a  fire,  which  not  long  before  had  been  kindled  in  its  skirts, 
had  spread  over  an  extensive  region  of  the  mountains  on  the  north-east, 
and  consumed  all  the  vegetation,  and  most  of  the  soil,  which  was  chiefly 
vegetable  mould,  in  its  progress.  The  whole  tract,  from  the  base  to  the 
summit,  was  alternately  white  and  dappled ;  while  the  melancholy  remains 
of  half-burnt  trees,  which  hung  here  and  there  on  the  immense  steeps, 
finished  the  picture  of  barrenness  and  death."  Old  Mr.  Crawford  is  said 
to  have  been  accustomed,  about  the  year  1845,  to  refer  to  the  great  fire 
which  reduced  Mt.  Crawford  to  its  present  condition,  as  occurring  some 
thirty  years  before.  A  similar  fire,  occurring  seventy  or  eighty  years 
ago  and  burning  for  several  weeks,  is  said  to  have  produced  the  barren 
aspect  of  Mt.  Monadnock,  in  the  south-west  part  of  the  state.  The 
time  may  arrive  when  the  record  of  these  irreparable  mischiefs,  destroy 
ing  the  vitality  of  the  mountains  and  leaving  only  naked  and  desolate 
rocks,  shall  possess  a  mournful  value. 

Several  years  after  this  visit  by  Dwight,  the  house  was  built  upon  the 
Davies  farm  by  a  Mr.  Henry  Hill,  which  is  yet  standing,  being  familiarly 
known  as  the  "Willey  house,"  and  interesting  as  a  monument  of  the 
fearful  tragedy  which  occurred  here  August  28th,  1826.  In  the  autumn 
of  1825,  Mr.  Samuel  Willey  with  his  family  moved  into  this  house.  In 
the  June  following,  a  slide  occurred  near  them  upon  the  mountain,  since 
called  "Mt.  Willey,"  which  rose  at  a  threatening  angle  some  two  thousand 
feet,  with  its  base  close  behind  the  house.  This,  which  was  the  warning 
of  the  impending  disaster,  at  first  greatly  alarmed  the  family,  and  they 
resolved  to  remove  from  the  notch.  But  Mr.  Willey,  on  reflection,  felt 
confident  that  such  an  event  was  not  likely  to  occur  again,  and  was  satis 
fied  with  building  a  place  of  shelter  to  which  the  family  might  fly,  if 
another  slide  seemed  to  threaten  their  home.  Later  in  the  summer  there 
was  a  long  hot  drought,  by  which  the  earth  had  been  dried  to  an  unusual 
depth,  thus  preparing  the  surface  to  be  operated  on  more  powerfully  by  a 
sudden  and  copious  rain.  This  began  to  fall  on  Sunday,  the  2;th  of 
August ;  and  on  the  next  day  the  storm  was  very  severe,  especially  in  the 
vicinity  of  the  mountains.  On  the  morning  of  Tuesday  the  sun  rose  in 
a  cloudless  sky,  and  the  air  was  remarkably  transparent.  During  the 
preceding  night  the  Saco  had  risen  twenty-four  feet,  and  swept  the  whole 
interval  between  the  notch  and  Conway.  The  storm  had  wrought  with 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.

a  terrible  effect  upon  the  sides  of  the  Mt.  Washington  range.  The 
whole  line  was  devastated  by  land-slides.  A  party  ascending  the  Ammo- 
noosuc  soon  after,  counted  thirty  along  their  path,  some  of  which  ravaged 
more  than  a  hundred  acres  of  the  wilderness.  On  the  declivities  towards 
North  Conway,  it  was  thought  that  this  one  storm  dismantled  more  of 
the  great  range  than  all  the  rains  of  a  hundred  years  before.  As  soon 
as  the  fate  of  the  Willey  family  became  known,  relatives  at  Conway,  and 
many  neighbors,  hurried  to  the  notch.  An  immense  slide  had  come 
down  the  mountain  directly  towards  the  house,  but  had  been  divided  by 
a  huge  boulder  thirty  feet  high,  in  the  rear  of  the  buildings,  uniting  again 
in  front.  A  portion  of  the  stable  had  been  swept  away.  The  doors  of 
the  house  were  all  open,  and  beds  and  clothing  showed  that  the  family 
had  hurriedly  left.  They  had  probably  fled  from  the  only  place  of  safety 
at  just  the  moment  to  be  overwhelmed  in  the  terrible  pathway  of  the 


Fig.   9. — THE  WILLEY   SLIDE  AND   MONUMENT. 

slide.  The  whole  family, — Mr.  Willey,  his  wife,  and  five  children,  together 
with  two  hired  men, — had  perished.  Search  for  the  bodies  was  at  once 
commenced.  The  first  found  was  that  of  one  of  the  hired  men,  David 
Allen,  a  man  of  powerful  frame  and  remarkable  strength.  He  was  found

near  the  top  of  a  pile  of  earth  and  shattered  timbers,  with  "hands 
clenched,  and  full  of  broken  sticks  and  small  limbs  of  trees."  The  bodies 
of  Mrs.  Willey  and  her  husband  were  also  discovered,  but  so  crushed  as 
to  be  hardly  recognized.  Rude  coffins  were  prepared,  and  the  next  day, 
Friday,  about  sunset,  they  were  buried  in  a  single  wide  grave,  and  the 
simple  burial  service  was  offered,  amid  the  solemnity  and  desolation  of 
the  mountains.  The  bodies  of  two  of  the  children  and  the  other  hired 
man,  David  Nickerson,  were  found  a  day  or  two  after,  and  also  buried, 
but  the  remaining  three  children  were  never  discovered. 

HOTELS,  AND  MODES  OF  ASCENT. 

Soon  after  the  completion  of  the  rude  bridle-path  in  1821,  by  Ethan 
Crawford,  it  was  perceived  that  a  house  of  some  sort  was  needed  upon 
the  summit,  where  visitors  could  spend  the  night.  Hence  Mr.  Crawford 
constructed  a  stone  cabin  near  the  top  of  Mt.  Washington,  by  the  side  of 
a  spring.  In  this  was  spread  an  abundance  of  soft  moss  for  beds ;  and 
thus  travellers  were  enabled  to  view  the  setting  and  rising  of  the  sun. 
After  a  while  a  small  stove  was  brought  up,  with  an  iron  chest  and  a 
long  roll  of  sheet  lead.  The  chest  was  the  receptacle  for  the  camping 
blankets,  and  the  lead  was  the  register  for  visitors.  Every  winter  this 
house  was  seriously  damaged.  The  roof  would  be  blown  away,  and  the 
stones  fall  down  from  the  walls, — the  chest  and  stove  remaining,  sadly 
rusted.  Finally,  at  the  great  storm  of  August  28,  1826,  when  the  Willey 
family  were  destroyed,  this  cabin,  with  the  iron  chest  and  the  blankets, 
was  swept  down  the  steep  slope  and  lost.  A  party  had  taken  possession 
for  the  night,  but  were  terrified  by  the  violence  of  the  storm,  and  had 
hastened  down  the  mountain  just  in  time  to  save  their  lives. 

In  1852,  J.  S.  Hall  and  L.  M.  Rosebrook  built  the  Summit  house  on 
the  very  top  of  the  mountain.  It  is  twenty-four  by  sixty-four  feet,  quite 
low,  with  very  thick  walls  of  stone  firmly  cemented  together,  and  bolted 
down  to  the  solid  rock.  Over  the  roof  are  four  strong  cables.  This 
house  has  now  stood  for  more  than  twenty  years. 

A  year  later  the  Tip-top  house  was  built  by  Samuel  F.  Spalding  &  Co. 
It  is  twenty-eight  by  eighty-four  feet,  and  was  built  in  the  same  substan 
tial  manner  as  the  other.  These  two  houses  were  originally  under 
different  management,  but  after  1859  tncy  were  both  leased  by  the 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  79 

proprietor  of  the  Alpine  house,  in  Gorham ;  and  many  thousand  people 
remember  their  stay  here  as  one  of  the  novel  experiences  of  the  mountain 
tour.  Within  two  years  the  Mt.  Washington  house, — a  new  and  very 
commodious  hotel  building,  provided  with  all  the  modern  improvements, 
and  quite  in  contrast  with  the  former  accommodations, — has  been  erected 
on  the  summit.  It  was  first  opened  to  the  public  in  the  summer  oi  1873, 
averaging  about  one  hundred  guests  daily.  J.  E.  Lyon  and  Walter  Aiken 
are  understood  to  be  the  proprietors ;  and  the  manager  is  Capt.  J.  W. 
Dodge. 

There  has  been  a  controversy  concerning  the  ownership  of  the  land 
upon  the  summit  of  Mt.  Washington.  In  the  early  legislation  of  New 
Hampshire  respecting  the  unoccupied  lands  of  the  state,  little  attention 
was  paid  to  exact  boundaries ;  consequently,  each  of  the  two  parties 
claiming  the  summit  had  reason  to  believe  it  to  be  included  within  their 
limits.  Mr.  Bellows,  of  Exeter,  owns  the  land  upon  the  east  side,  and 
was  the  party  in  possession  till  about  fifteen  years  ago,  when  his  tenants 
were  ejected  by  the  sheriff  acting  for  Coe  &  Pingree,  of  Bangor,  Me.,  and 
Salem,  Mass.  Probably  more  than  twenty-five  thousand  dollars  was 
spent  in  contesting  the  matter  of  ownership  before  the  courts,  which  has 
since  been  settled  through  purchase,  by  Coe  &  Pingree,  of  all  the  rights 
and  claims  of  the  former  occupant. 

The  first  good  public  house  for  summer  visitors  was  built  near 
the  Giant's  grave,  about  seven  miles  west  from  the  base  of  Mt.  Wash 
ington,  and  came  into  the  hands  of  Mr.  Fabyan.  This  was  destroyed 
by  fire  about  twenty  years  since.  The  Fabyan  house,  a  large  and  ele 
gant  hotel,  has  been  recently  built  at  this  place,  the  Giant's  grave  being 
levelled  down  for  its  reception.  It  was  first  opened  to  guests  in  1873. 
The  well  known  White  Mountain  house,  about  a  mile  west  from 
this  place,  was  built  by  Mr.  Rosebrook,  a  descendant  of  the  pioneer  of 
that  name,  about  thirty  years  since.  About  four  miles  farther  west,  fol 
lowing  the  Ammonoosuc  river,  we  come  to  the  Twin  Mountain  house,  one 
of  the  finest  and  most  complete  of  the  mountain  hotels.  The  Notch 
house,  kept  by  T.  J.  Crawford,  is  no  longer  in  existence ;  but  its  place  has 
been  more  than  made  good  by  the  large  and  well  kept  hotel,  a  quarter  of 
a  mile  farther  north,  known  as  the  Crawford  house.  At  the  foot  of  the  Mt. 
Washington  Railway  is  the  Marshfield  house,  a  smaller  but  comfortable 


80  PHYSICAL    GEOGRAPHY. 

hotel,  with  accommodations  for  fifty  guests.  Upon  the  east  side  is  the 
Glen  house,  at  the  lower  end  of  the  carriage-road.  This,  and  the  Fabyan 
house,  are  the  largest  hotels  near  Mt.  Washington,  either  being  capa 
ble  of  accommodating  five  hundred  guests  at  one  time.  The  Profile  and 
Flume  houses,  among  the  Franconia  Mountains,  and  the  large  and  well 
appointed  hotels  of  Plymouth,  Littleton,  Bethlehem,  Lancaster,  Jefferson, 
North  Conway,  and  other  places,  too  numerous  for  particular  mention 
here,  show  the  popularity  of  this  portion  of  our  state  as  a  summer 
resort. 

There  are  now  three  ways  of  ascending  Mt.  Washington  from  below, — 
two  from  the  west  and  one  from  the  east ;  or,  a  railway,  a  carriage-road, 
and  a  bridle-path.  In  1840,  the  bridle-path  to  the  summit  was  cut  from 
the  notch  over  Mts.  Clinton,  Pleasant,  Franklin,  and  Monroe,  to  Washing 
ton,  being  nine  miles  in  length.  It  affords  a  magnificent  panorama  of 
mountain  scenery,  passing  along  over  the  treeless,  wind-swept  summits 
of  the  range ;  but,  on  account  of  its  tiresomeness,  few  now  ascend  by  this 
route.  A  still  longer  bridle-path  was  soon  afterwards  opened  by  Mr. 
Davis  over  Mt.  Crawford,  and  thence  along  the  east  side  of  Dry,  or  Mt. 
Washington  river,  but  it  is  now  wholly  disused.  Still  later,  the  bridle 
path  first  opened  by  Ethan  Crawford  from  the  Giant's  grave  to  "  Cold 
spring,"  or  the  base  of  Washington,  was  enlarged  and  became  a  carriage- 
road.  This  was  in  use,  though  kept  in  poor  repair,  till  it  was  superseded 
by  the  "Fabyan  turnpike,"  in  1866.  It  terminated  about  a  quarter  of  a 
mile  higher  up  the  mountain  than  the  lower  depot  of  the  railway,  known 
as  "Ammonoosuc,"  formerly  "Marshfield." 

In  June,  1853,  a  company  was  chartered  to  build  a  carriage-road  from 
the  Glen  to  the  Tip-top  house,  with  a  capital  stock  of  fifty  thousand 
dollars.  The  length  of  this  road  is  a  little  less  than  eight  miles.  By  the 
original  design  it  was  to  be  sixteen  feet  wide,  macadamized,  and  to  have 
a  protection  wall  three  feet  high  in  dangerous  places.  Its  average  grade 
is  twelve  feet  in  one  hundred,  and  the  steepest  is  about  sixteen  feet  in 
one  hundred,  two  and  a  half  miles  from  the  Glen.  The  work  of  its  con 
struction  was  commenced  in  1855,  under  the  superintendence  of  C.  H. 
V.  Cavis,  engineer.  It  was  carried  as  far  as  the  "  ledge,"  or  half  way,  in 
1856,  and  in  1861  it  was  completed  to  the  summit.  There  is  a  small 
house  on  this  road  half  way  up  the  mountain,  at  the  point  where  the 


EXPLORATIONS    AMONG   THE    WHITE    MOUNTAINS.  8 1 

trees  terminate  and  the  arctic  zone  commences.  This  is  occupied  in 
summer  by  a  force  of  laborers,  by  whom  the  roadway  is  kept  in  a  first- 
rate  condition.  But  the  greatest  triumph  of  engineering  skill  is  on  the 
west  side  of  the  mountain,  and  was  first  projected  while  the  carriage- 
road  was  in  process  of  construction,  but  was  not  realized  till  several 
years  later. 

The  first  effort,  in  the  direction  of  ascending  Mt.  Washington  by  steam- 
power,  was  made  by  Mr.  Sylvester  Marsh,  now  residing  at  Littleton,  N. 
H.,  and  the  president  of  the  Mt  Washington  Railway  Company.  He 
invented  the  special  contrivances  needed  to  adapt  motive  machines  to  a 
highly  inclined  plane.  It  was  found  very  difficult  at  the  outset  to  con 
vince  mechanicians  and  capitalists  of  the  feasibility  of  this  ascending 
railway.  Mr.  Marsh  commenced  the  work,  relying  chiefly  upon  his  own 
private  resources,  and  little  encouragement  was  afforded  by  capitalists 
till  an  engine  was  actually  running  over  a  portion  of  the  route.  In  1858 
the  application  was  made  to  the  legislature  of  New  Hampshire  to  grant 
a  charter  for  a  steam  railway  from  their  bases  to  the  summits  of  Mts. 
Washington  and  Lafayette.  A  model  of  the  invention  was  exhibited, 
and  it  was  stated  that  the  petitioner  and  his  friends  would  assume  the 
expense  of  the  enterprise.  After  considerable  ridicule,  this  charter  was 
charitably  granted,  with  the  usual  formula  of  railroad  laws  in  the  state. 
The  actual  work  of  construction  was  delayed  for  a  number  of  years.  As 
a  preliminary  operation  it  was  found  desirable  to  build  the  new  turnpike, 
already  noticed,  from  the  stage  road  to  the  point  where  the  ascent  by 
rail  should  commence,  upon  which  work  was  begun  in  April,  1866.  Some 
five  miles  from  the  starting-point  this  road  passes  through  a  clearing  of 
perhaps  a  hundred  acres,  called  "  Twin  River  Farm."  This  spot  is  about 
five  hundred  feet  above  the  White  Mountain  house,  and  is  spoken  of  as 
p'ossibly  the  site  of  the  future  junction  of  the  Mt.  Washington  Railway 
with  the  extension  of  the  Boston,  Concord  &  Montreal  Railroad  branch 
from  near  Littleton,  now  nearly  completed  to  the  Fabyan  house. 

The  Mt.  Washington  railroad  was  commenced  in  May,  1866.  It  starts 
from  a  point  2,668  feet  above  the  level  of  the  sea,  and  3,625  below  the 
summit.  The  distance  traversed  is  two  miles  and  thirteen  sixteenths. 
The  average  grade  is  1,300  feet  to  the  mile,  the  maximum  being  1,980 
feet  to  the  mile,  or  thirteen  and  a  half  inches  to  the  yard.  There  are

82  PHYSICAL    GEOGRAPHY. 

nine  curves  on  the  line,  varying  from  497  to  945  feet  radius.  The  first 
year  the  road  was  built  a  distance  of  about  a  quarter  of  a  mile.  In 
1867  the  track  was  extended  to  "Waumbek  Junction,"  where  it  crosses 
Fabyan's  foot-path,  a  distance  of  one  mile  and  eight  rods.  Work  was 
resumed  May  7,  1 868,  and  in  eighty-four  working  days  it  had  advanced 
more  than  a  mile,  or  to  the  top  of  "Jacob's  Ladder."  The  work  was 
continued  till  cold  weather  set  in,  and  the  last  few  rods  of  the  track  was 
laid  in  July,  1869.  The  road  was  built  under  the  superintendence  of  J.  J. 
Sanborn,  of  Franklin,  N.  H.,  at  a  total  cost,  including  depots,  turn-outs, 
and  rolling  stock,  of  about  $150,000.  The  indispensable  peculiarity  of 
this  railway  is  its  central  cog-rail,  which  consists  of  twro  pieces  of  wrought 
angle  iron,  three  inches  wide  and  three  eighths  of  an  inch  thick,  placed 
upon  their  edges,  parallel  to  each  other,  and  connected  by  strong  iron 
pins  an  inch  and  a  half  in  diameter,  and  four  inches  apart  from  centre  to 
centre.  The  teeth  of  the  driving  wheel  of  the  engine  play  into  the 
spaces  between  the  bolts,  and,  as  it  revolves,  the  whole  engine  is  made  to 
move,  resting  upon  the  outer  rails.  These  cog-rails  cost  about  two  dol 
lars  per  foot,  delivered  at  the  base  of  the  mountain.  The  appliances  for 
stopping  trains  are  of  the  most  perfect  kind.  Both  friction  and  atmos 
pheric  brakes  are  employed,  and  their  complete  reliability  has  been 
proved  by  the  severest  tests.  The  speed  of  descent  is  entirely  regulated 
by  their  means  without  the  use  of  steam.  The  engines  employed  have 
been  built  by  Walter  Aiken,  of  Franklin,  N.  H.,  each  weighing  six  and  a 
half  tons,  and  rated  at  about  fifty  horse-power  ;  but  on  account  of  their 
gearing  they  are  practically  two  hundred  horse-power.  When  moving, 
the  engine  always  takes  the  down-hill  end  of  the  train.  While  this  rail 
way  was  in  process  of  construction  it  was  visited  by  a  Swiss  engineer, 
who  took  away  drawings,  etc.,  of  the  machinery  and  track,  from  which  a 
similar  road  has  been  since  built  upon  Mt.  Rhigi  in  Switzerland  :  and 
thus  we  have  set  an  example  worthy  of  imitation  to  an  older  country. 
This  road  has  a  double  track,  and  its  length  and  grades  are  about  the 
same  as  upon  Mt.  Washington. 

CASUALTIES  UPON  Mr.  WASHINGTON. 

Before  the  construction  of  these  improved  and  even  luxurious  methods 
of  ascent,  several  persons  had  lost  their  lives  in  attempting  to  climb  this 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  83 

mountain,  generally  in  consequence  of  neglecting  the  advice  of  guides. 
The  first  was  an  English  baronet,  named  Strickland.  He  went  up  from 
the  notch  late  in  October,  1851.  Disregarding  the  advice  of  his  guide, 
he  pushed  on  to  the  summit,  proposing  to  descend  by  Fabyan's  path. 
He  seems  to  have  become  bewildered,  and,  after  falling  down  precipitous 
places  several  times,  to  have  perished  from  cold  and  exhaustion,  probably 
in  less  than  twelve  hours  after  he  started. 

On  the  24th  of  September,  1855,  Miss  Lizzie  Bourne,  of  Kennebunk, 
Me.,  perished  within  thirty  rods  of  the  summit.  With  an  uncle  and  cousin 
she  climbed  the  mountain  on  foot ;  but  after  reaching  the  Half-way  house 
the  clear  sky  disappeared  ;  they  became  enveloped  in  a  thick  cloud,  and 
strong  winds  met  them  in  front.  Not  knowing  their  nearness  to  the 
summit,  they  were  compelled  to  shelter  themselves  behind  a  few  rough 
stones ;  and  Miss  Bourne  was  not  strong  enough  to  survive  the  shock. 
A  pyramid  of  stones  close  to  the  railroad  marks  the  spot. 

August  /th,  1856,  Benjamin  Chandler,  of  Wilmington,  Del.,  started 
from  the  Glen  house  for  the  summit  late  in  the  afternoon.  It  was  rainy, 
windy,  and  very  cold.  He  was  about  seventy-five  years  of  age.  He 
seems  to  have  wandered  from  the  path,  but  no  one  knows  how  long  he 
survived.  His  remains  were  not  found  for  more  than  a  year,  when  they 
were  accidentally  discovered  about  half  a  mile  east  of  the  summit. 

The  most  terrible  exposure  which  any  person  has  survived  upon  Mt. 
Washington  was  that  of  Dr.  B.  L.  Ball,  of  Boston,  late  in  October,  1855. 
This  gentleman  walked  from  the  Glen  house  to  the  Half-way  house, 
while  workmen  were  engaged  in  building  the  carriage-road.  The  moun 
tain  was  covered  with  clouds,  and,  after  climbing  some  distance  above 
the  "ledge,"  he  returned  to  the  camp  and  spent  the  night  with  the 
laborers.  The  next  morning  the  clouds  seemed  about  breaking,  and  he 
•started  with  the  intention  of  reaching  the  summit  if  possible.  The  rain 
was  changed  to  sleet  and  snow,  and  the  temperature  fell  very  much. 
Though  very  uncomfortable,  Dr.  Ball  believed  himself  to  be  near  the 
summit,  and  struggled  on,  understanding  that  he  could  find  provisions 
and  shelter  in  one  of  the  houses  there.  He  describes  the  storm  as  fol 
lows  :  "  I  could  not  have  believed  that  the  storm  could  be  more  violent 
than  it  had  been.  Yet  here  it  was  more  furious  than  ever.  It  now  had 
the  full  sweep  of  the  mountain  top,  the  highest  point  of  the  whole  group, 


84  PHYSICAL    GEOGRAPHY. 

of  the  loftiest  mountain  for  hundreds  of  miles  around.  If  ten  hurricanes 
had  been  in  deadly  strife  with  each  other  it  could  have  been  no  worse. 
The  winds,  as  if  locked  in  mortal  embrace,  tore  along,  whirling-  and  twist 
ing,  and  mingling  their  roaring  with  the  flinty  rattling  of  the  snow  grains 
in  one  confused  din."  Dr.  Ball  did  not,  however,  actually  reach  the  sum 
mit,  and,  after  many  hours  spent  in  the  endeavor,  buffeting  the  storm,  he 
was  obliged  to  abandon  his  purpose,  and  set  out  to  descend.  But  his 
footprints  had  been  obliterated  by  the  storm,  and,  losing  his  way,  he 
found  himself  unable  to  judge  from  what  direction  he  had  come.  He 
pursued  his  way  downward,  however,  till  he  reached  the  stunted  and 
tangled  growth  of  spruce  at  the  upper  limit  of  trees.  Here  night  came 
on,  and,  building  himself  a  sort  of  shelter  from  the  wind  and  snow  wTith 
the  aid  of  an  umbrella,  he  lay  down,  knowing  that  to  yield  to  sleep  would 
be  fatal.  The  night  was  bitterly  cold,  water  being  frozen  thick  at  the 
camp  below  in  a  room  adjoining  one  which  had  a  fire.  But  even  in  this 
situation,  he  remarks, — "  It  was  not  without  some  satisfaction  that  I  looked 
around  me,  and  beheld  the  results  of  my  labors.  Notwithstanding  the 
open  front,  a  bed  of  snow,  a  frosty  rock  on  one  side,  a  congealed  mass 
of  snow  and  brush  on  the  other,  I  was  happy  in  the  reflection  that  my 
lot  here  was  infinitely  better  than  it  could  have  been  outside.  Drawing 
myself  up  into  as  small  a  compass  as  possible  under  my  covering,  I  pre 
pared  to  pass  a  long,  long  night, — the  longest  of  my  life."  He  says  that 
he  was  enabled  to  keep  awake  by  the  multiplicity  of  thoughts  which 
crowded  through  his  mind,  and  by  taking  constrained  and  almost  con 
stantly  varied  positions.  "When  the  first  rays  of  light  appeared  in  the 
morning,  so  much  sooner  had  the  night  passed  than  I  had  expected,  that 
I  presumed  the  moon  was  shining.  My  body  was  stiff  and  rigid  with 
cold,  and  pressing  upon  the  ground  with  such  a  senseless  weight,  that  it 
seemed  to  me  I  had  become  a  part  of  the  mountain  itself."  The  second 
day  the  view  was  still  obscured  by  clouds,  and  was  spent  by  him  wan 
dering  about  in  the  snow.  Unable  to  obtain  a  sight  of  the  Glen  house 
below,  and  not  daring  to  descend  into  the  mazes  of  the  forests,  he  returned 
to  spend  a  second  night  in  the  same  place  as  before.  During  this  night, 
he  says,  "the  thought  occurred,  What  if  I  am  obliged  to  stay  out  a  night 
after  this,  without  food,  drink,  or  sleep  ?  After  a  short  consideration, 
taking  into  account  my  present  state, — that  which  had  passed,  and  the 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  85 

chances  to  come, — I  concluded  that,  terrible  as  it  might  be,  I  should  be 
able  to  survive  it ;  but  whether  I  could  then  walk  or  not,  I  was  unable  to 
decide."  The  next  day  was  clear ;  but  not  being  able  to  make  out  the  Glen 
house,  as  soon  as  he  was  able  to  walk,  which  he  says  was  after  about  two 
hours,  he  started  out  to  make  a  circuit  for  its  discovery,  higher  up  the 
mountain.  On  this  day  he  says  that  he  no  longer  felt  the  gnawings  of 
hunger,  but  was  oppressed  by  a  burning  thirst.  "I  thought  I  should  not 
wish  to  eat,  even  were  food  at  hand.  But  I  could  not  remain  ignorant  of 
the  fact  that  I  was  becoming  weaker.  This  I  perceived  by  the  effort  I  was 
obliged  to  make  to  hold  my  body  erect,  it  inclining  to  stoop  forward  like 
a  man  bowed  down  with  old  age.  Often  I  raised  myself  upright,  but  was 
very  soon  in  the  same  bent  posture."  He  was  found  in  the  afternoon  of 
this  the  third  day  of  his  exposure,  still  in  good  spirits,  after  having  en 
dured  for  sixty  hours  the  severe  cold  of  the  mountain,  without  food  or 
sleep.  The  party  by  whom  Dr.  Ball  was  rescued,  consisting  of  Francis 
Smith,  J.  S.  Hall,  and  others,  had  been  also  engaged  the  preceding  day 
in  the  search,  but  had  given  up  all  expectation  of  meeting  with  him  alive. 

On  February  22,  1872,  private  William  Stevens,  of  the  Signal  Service, 
U.  S.  A.,  died,  after  a  sudden  attack  of  paralysis.  It  does  not  appear 
that  this  malady  was  induced  by  the  special  perils  of  the  service,  as  he 
had  spent  a  winter  in  Alaska,  and  another  at  Fort  Russell,  though  an 
unnecessary  yielding  to  sedentary  habits  may  induce  disease  in  the  most 
vigorous  constitution.  The  body  of  Mr.  Stevens  was  brought  down  the 
mountain  by  a  party  of  six  persons,  and  buried  at  Littleton. 

During  the  summer  of  1873,  one  of  the  section  hands  on  the  railway 
met  with  a  fatal  accident.  He  was  sliding  down  the  middle  rail  on  a 
board,  and  collided  with  an  engine  which  was  coming  up  the  mountain. 
His  velocity  of  descent  (a  mile  per  minute)  prevented  him  from  stopping, 
and  his  head  was  split  entirely  open.  The  site  of  the  accident  was  at 
Jacob's  Ladder. 

WINTER  VISITS  TO  THE  SUMMIT. 

The  thrilling  and  melancholy  recital  of  such  events  as  these  has  not 
failed  to  invest  the  mountains  with  something  of  tragic  interest.  Their 
changeableness  in  atmosphere  and  temperature,  the  impenetrability  of 
their  fogs,  and  the  suddenness  and  merciless  fury  of  their  storms,  often 


86  PHYSICAL    GEOGRAPHY. 

demand  precaution  and  judgment  in  summer  visits  to  their  summits. 
Previous  to  the  expedition  of  1870,  few  had  been  found  so  hardy  as  to 
attempt  the  ascent  in  winter.  In  the  month  of  November,  1855,  a  month 
after  Dr.  Ball's  experience,  another  party  succeeded  in  reaching  the  top 
in  safety,  and  in  enjoying  a  good  view.  One  of  the  most  hardy  men,  in 
the  party  that  rescued  Dr.  Ball,  said  that  with  a  friend  he  attempted  to 
make  the  ascent  in  February  ;  but  when  they  arrived  within  a  mile  of  the 
summit,  they  were  obliged  to  turn  back  almost  frozen.  Before  1 870,  only 
two  instances  are  recorded  of  visits  to  the  summit  during  the  winter 
months.  The  first  was  made  December  7th,  1858,  by  Mr.  Osgood,  of 
Lancaster,  who  went  up,  accompanied  by  one  or  two  friends,  to  serve  a 
legal  process  upon  property  there.  They  found  frost  formed  upon  the 
windows  a  foot  and  a  half  in  thickness.  It  also  covered  the  furniture 
and  the  walls,  giving  them  the  appearance  of  a  "  snow  cavern."  On  their 
return,  they  were  overtaken  by  one  of  the  frost  clouds  peculiar  to  the 
mountains  in  winter.  "When  first  seen  it  was  small  in  magnitude,  but  it 
increased  in  size  with  alarming  velocity,  soon  spreading  over  the  entire 
south.  They  had  just  entered  the  woods  at  the  base  of  the  ledge,  when 
it  came  upon  them.  So  icy  and  penetrating  was  its  breath,  that  to  have 
encountered  its  blinding,  freezing  power  on  the  unprotected  height,  would 
have  been  to  have  perished  with  it  as  a  pall  to  cover  them.  The  party 
reached  the  Glen  in  safety,  and  were  heartily  welcomed  by  their  friends, 
who,  well  knowing  the  danger  attending  this  never  before  accomplished 
feat,  awaited  them  with  much  anxiety." 

The  other  ascent  was  made  by  a  party  of  three, — J.  H.  Spalding,  F. 
White,  and  C.  C.  Brooks,  all  from  Lancaster, — on  February  n,  1862.  A 
stereograph,  obtained  at  this  visit,  exhibited  the  interior  of  the  Summit 
house,  with  snow-drifts  which  had  been  sifted  in  through  cracks  in  the 
building.  This  party  remained  on  the  top  two  clays  and  nights,  experi 
encing  a  driving  snow-storm  of  thirty-six  hours'  duration,  and  were  repaid 
by  "one  of  the  most  magnificent  sunrise  scenes  that  imagination  can 
picture."  The  most  extreme  cold  during  their  stay  was  five  degrees 
below  zero.  One  of  the  objects  of  this  visit  was  evidently  to  obtain  some 
acquaintance  with  the  storms  of  the  mountain.  Their  account  concludes : 
"We  were  remarkably  well  satisfied  with  the  weather,  and  were  very 
lucky  about  climbing  over  the  ice-clad  rocks.  Should  others  attempt  to 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  87 

go  up  among  the  clouds,  for  their  own  sake  they  should  go  prepared  for 
the  worst.  An  iron-pointed  staff,  with  an  axe,  and  plenty  of  food  and 
clothing,  are  indispensable." 

In  the  winter  of  1870-71,  the  possibility  of  climbing  the  mountain  in 
the  winter  was  thoroughly  established.  Thirty-eight  persons  went  up 
and  down, — some  of  them  several  times, — the  total  number  of  ascents 
being  seventy.  A  register  of  the  trips  was  given  in  the  report  for  1870. 
The  expedition  was  undertaken  in  opposition  to  the  judgment,  experience, 
and  advice  of  those  most  familiar  with  the  mountain. 

Mrs.  O.  E.  Freeman,  of  Lancaster,  made  the  ascent  of  Mt.  Washington,  Tuesday, 
January  24,  1874.  on  foot.  She  is  a  daughter  of  "Old  Ethan  Crawford,"  of  White 
Mountain  fame,  and  is  doubtless  the  first  woman  who  ever  attempted  to  accomplish 
his  feat  in  winter.  She  was  accompanied  by  her  sister  Mrs.  Durgin,  her  brother 
William  H.  Crawford,  and  nephew  Ethan  Crawford,  Jr.  They  did  not  anticipate  going 
to  the  top  at  the  starting,  but  thought  they  would  walk  up  a  short  distance  to  see  the 
railroad,  etc.  They  finally  concluded  to  go  to  the  top  if  possible,  and  made  the 
distance  in  three  hours,  walking  upon  the  railroad  sleepers  most  of  the  way, — which 
required  not  a  little  self-possession  and  endurance,  as  they  are  in  many  places  ten  and 
fifteen  feet  above  the  rocks  below,  and  covered  with  ice  and  snow,  so  that  a  single 
misstep  might  prove  fatal  to  one  walking  upon  them.  Having  been  born  under  the 
very  shadowrs  of  these  grand  old  hills,  these  ladies  have  become  inured  to  cold,  frost, 
and  snow,  and  enjoy  rather  than  shrink  from  a  little  exposure.  Mrs.  Freeman  describes 
the  trip  as  "glorious  fun,"  and  expresses  the  hope  that  all  her  lady  friends  may  have 
the  pleasure  of  making  it  in  winter. 

ESTABLISHMENT  OF  AN  OBSERVATORY. 

The  increasing  interest  during  the  past  few  years  in  the  subject  of 
meteorology,  the  remarkable  character  of  the  phenomena  which  would  be 
observed  during  a  winter  residence  on  any  of  these  mountain  summits, 
and,  within  the  last  few  years,  the  obvious  bearing  which  these  must  have 
upon  the  great  problem  of  meteorology,  the  prediction  of  the  weather, 
together  with  the  expensive  outfit  which  it  was  seen  must  be  necessary  to 
render  such  an  enterprise  possible,  seem  to  have  given  rise  to  many 
stories  of  large  rewards  which  had  been  offered  to  any  one  who  should 
accomplish  this  object.  As  long  ago  as  1858  a  report  was  current,  among 
guides  and  others,  that  the  Smithsonian  Institution  had  offered  a  thousand 
dollars  to  any  one  who  would  spend  a  winter  on  the  highest  summit,  for 


88  PHYSICAL    GEOGRAPHY. 

the  purpose  of  taking  meteorological  observations.  Others  said  that  a 
firm  in  Boston  had  offered  five  thousand  dollars  for  the  same  object,  with 
the  avowed  purpose  of  publishing  the  journal  of  the  observers'  experience, 
expecting  to  be  reimbursed  for  the  large  expenditure  by  the  sale  of  the 
books.  In  the  efforts  during  the  fall  of  1870  to  raise  funds  for  the  me 
teorological  expedition  then  undertaken,  every  such  report  was  carefully 
scrutinized,  but  none  could  be  traced  to  any  reliable  source.  Even 
to  the  present  time,  people  at  the  mountains  still  insist  that  somebody 
had  offered  a  very  large  sum  for  the  purpose  accomplished  by  the  Mt. 
Washington  expedition. 

Perhaps  the  first  attempt  to  establish  a  scientific  observatory  upon  the 
summit  of  Mt.  Washington  was  made  in  1853,  by  D.  O.  Macomber, 
president  of  the  Mt.  Washington  Road  Company.  I  have  seen  no  one 
who  recalls  the  extent  of  the  effort  made  at  this  time,  but  can  reproduce 
a  circular  setting  forth  the  importance  of  the  enterprise,  and  a  petition 
to  congress  for  assistance. 

"UNITED  STATES  OBSERVATORY  ON  MT.  WASHINGTON. 

"The  arguments  in  favor  of  establishing  a  permanent  building  on  the  top 
of  Mt.  Washington,  for  scientific  purposes,  are  numerous  and  weighty. 
Among  them  are,— 

"i.  Mt.  Washington  is  the  highest  accessible  point  of  land  in  the  United  States,  east 
of  the  Rocky  Mountains,  being  6,285  feet  above  the  level  of  the  sea,  according  to 
actual  measurements  made  by  William  A.  Goodwin,  Esq.,  civil  engineer,  in  1852,  who 
was  employed  for  that  purpose  by  the  Atlantic  &  St.  Lawrence  Railroad  Company. 

"  2.  The  construction  of  a  Macadamized  carriage-road,  chartered  by  the  state  of  New 
Hampshire,  in  July,  1853,  and  which  will  be  completed  in  1854,  will  render  the  ascent 
of  the  mountain  easy  for  such  portions  of  the  year  as  it  is  desirable  to  continue  scien 
tific  observations. 

"  3.  A  line  of  telegraph  is  to  be  constructed  to  the  summit  of  Mt.  Washington,  con 
necting  with  the  line  now  in  operation  from  Portland  to  Montreal,  and  which  line 
connects  at  Portland  with  lines  to  Boston,  New  York,  Washington,  Cincinnati,  £c.,  &c. 

"  4.  A  large  hotel  is  to  be  erected  on  the  top  of  the  mountain  by  the  Mt.  Washington 
Road  Company,  which  hotel,  together  with  the  necessary  out-buildings,  will  occupy  all 
the  available  space  on  the  summit  which  is  suitable  for  such  purposes,  and  which  is 
already  laid  out  and  commenced,  and  will  be  completed  during  the  year  1854.  The 
company  who  erected  the  first  building  of  any  kind  on  the  summit,  form  a  portion  of 
the  present  incorporation,  and  merge  all  their  interests  in  the  new  building. 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS.  89 

"5.  It  has  been  satisfactorily  ascertained  that  no  private  individuals  have  any  title  to 
the  surface  of  the  summit  of  Mt.  Washington,  but  the  same  is  held  by  the  state  of 
New  Hampshire,  from  whom  and  by  the  legislature  of  which  the  charter  of  the  Mt. 
Washington  Road  Company  was  granted. 

"6.  When  the  building,  with  an  observatory  attached,  shall  be  completed,  and  fur 
nished  with  the  necessary  instruments,  scientific  observations  may  be  kept  up  through 
out  the  entire  year,  giving,  over  the  telegraph  wires  to  Washington,  New  York,  Cincin 
nati,  £c.,  three  times  each  day  (viz.,  sunrise,  meridian,  and  sunset),  the  record  of 
the  thermometer,  barometer,  and  wind,  and  also  the  duration  and  power  of  storms. 

"7.  Mt.  Washington  has  been  for  years  past,  and  will  be  for  years  to  come,  the  cul 
minating  point  of  many  of  the  most  important  and  interesting  observations  connected 
with  the  coast  surveys  under  charge  of  Prof.  Bache,  and  which  are  now  becoming  of 
so  much  acknowledged  practical  utility  to  the  great  commercial  interests  of  the  United 
States,  and  of  the  world. 

"8.  It  is  evident  that  if  an  observatory,  for  the  use  of  the  government  and  the  benefit 
of  the  public,  is  ever  to  be  erected  on  the  summit  of  Mt.  Washington,  it  should  be 
built  in  connection  with  the  house  now  about  to  be  commenced,  and  both  constructed 
in  the  most  durable  and  permanent  manner,  not  only  to  resist  the  force  of  the  elements, 
but  also  for  the  safety  and  comfort  of  those  whom  it  may  be  necessary  to  station  there 
during  the  winter  season  for  scientific  observations,  and  who  will  be  wholly  inaccessible 
to  those  below  for  at  least  five  consecutive  months. 

"9.  The  proposition  to  the  United  States  government  will  embrace  all  the  advan 
tages  of  furnishing  an  excellent  road  for  its  use,  and  keeping  the  same  in  repair, 
erecting  a  tower  for  scientific  observations,  with  movable  dome,  and  with  a  centre 
isolated  pillar  on  which  to  place  instruments,  with  sufficient  rooms  for  observations,  and 
also  for  the  use  of  any  scientific  corps  it  may  be  necessary  to  place  there,  with  appur 
tenances  for  heating  the  same  during  the  winter  months.  These  rooms,  together  with 
the  observatory,  to  be  entirely  under  the  control  of  the  government,  and,  if  desirable, 
built  under  the  inspection  of  scientific  gentlemen  to  be  named  by  the  president." 

"To  the  Honorable  Senate  and  House  of  Representatives  of  the  United 
States  in  Congress  assembled: 

"The  president  and  directors  of  the  Mt.  Washington  Road  Company  propose 
to  the  United  States  government  to  build,  for  the  use  of  the  government 
and  for  scientific  purposes,  an  observatory  on  the  top  of  Mt.  Washington, 
in  the  state  of  New  Hampshire,  in  the  manner  following,  to  wit : 

"  i.  The  observatory  to  be  25  feet  square,  with  walls  4  feet  in  thickness,  and  to  be 
not  less  than  40  feet  high  above  the  top  of  Mt.  Washington. 

"2.  The  rooms  inside  to  be  17  feet  square,  or  of  an  octagon  form,  and  a  stone  pillar 
to  be  erected  in  the  centre  from  the  foundation  to  the  top,  entirely  disconnected  with

the  walls,  with  stone  beams  projecting  from  it  in  the  several  stories,  for  the  reception 
of  transit  instrument,  transit  clock,  artificial  horizon,  &c.,  £c. 

"3.  The  walls  of  the  observatory  to  be  built  of  stone,  in  the  most  substantial  and 
durable  manner,  with  a  traversing  dome,  fitted  according  to  the  most  approved  scien 
tific  buildings  of  this  character. 

"4.  The  observatory  to  be  erected  as  a  tower  to,  and  in  connection  with,  a  large 
substantial  stone  building,  no  feet  long  by  50  deep,  with  an  ell  90  by  40.  The  whole 
to  be  three  stories  high,  with  flat  roof,  and  calculated  to  accommodate  one  hundred 
and  fifty  visitors  during  the  summer  months. 

"5.  The  Mt.  Washington  Road  Company,  under  their  charter  of  incorporation,  a 
copy  of  which  is  herewith  submitted,  will  build  a  substantial  carriage-road  from  the 
base  to  the  top  of  Mt.  Washington,  with  a  grade  not  exceeding  one  foot  in  eight,  and 
eight  miles  long,  to  be  completed  before  July,  1855. 

"6.  The  company  will  place  this  road  at  the  service  of  the  U.  S.  government,  and 
will  transport  all  instruments,  furniture,  and  persons  belonging  to  or  connected  with 
the  government  observatory,  over  the  same,  free  of  charges  of  any  kind,  at  all  times 
when  the  said  road  shall  not  be  rendered  impassable  by  the  elements. 

"7.  The  Mt.  Washington  Road  Company  will  erect,  or  cause  to  be  erected,  a  sub 
stantial  line  of  telegraph  wires  from  the  top  of  Mt.  Washington,  to  connect  with  the 
line  already  in  operation  along  the  line  of  the  Atlantic  &  St.  Lawrence  Railroad, 
which  is  distant  only  eight  miles  from  the  base  of  the  mountain,  and  which  telegraph 
line  connects  at  Portland,  Me.,  with  the  lines  extending  to  New  York,  Philadelphia, 
Boston,  Washington,  Cincinnati,  and  other  portions  of  the  United  States. 

"8.  To  facilitate  the  continuation  of  scientific  observations  during  the  entire  year  on 
the  top  of  Mt.  Washington,  the  Mt.  Washington  Road  Company  will  place  at  the 
disposal  of  the  U.  S.  government  such  portion  of  the  building  as  shall  be  necessary 
for  the  accommodation  of  those  who  may  be  in  the  employment  of  the  government,  or 
of  any  scientific  society  approved  of  by  government,  without  charge,  and  will  transport 
at  their  own  cost  over  their  road,  all  fuel,  provisions,  &c.,  for  the  support  and  conven 
ience  of  such  persons. 

"9.  To  enable  the  Mt.  Washington  Road  Company  to  build  this  national  observa 
tory  in  the  manner  stated  above,  and  in  accordance  with  plans  of  the  same  herewith 
submitted,  and  for  the  furnishing  a  carriage-road,  telegraph  communication,  and  all  the 
facilities  above  stated  for  the  use  of  the  United  States  government  and  the  cause  of 
science  throughout  the  world,  they  ask,  in  consideration,  an  appropriation  of  $50,000, 
to  be  expended  under  a  joint  commission  of  two  persons,  the  one  to  be  named  by  the 
government,  and  the  other  to  be  the  president  of  the  Mt.  Washington  Road  Company. 
"  D.  O.  MACOMBER,  President  Mt.  Washington  Road  Company. 

"December  ist,  1853." 

In  1859,  Jonathan  Marshall,  a  recent  graduate  of  Dartmouth  college, 
conceived  the  idea  of  spending  a  winter  upon  the  summit  of  Mt.  Wash- 


EXPLORATIONS   AMONG   THE   WHITE    MOUNTAINS.  9 1 

ington  for  meteorological  purposes.  He  received  encouragement  from 
Prof.  Joseph  Henry,  of  the  Smithsonian  Institution,  and  was  allowed  to 
occupy  one  of  the  houses.  An  unexpected  snow  storm  delayed  some  of 
his  preparations,  and  meanwhile  other  considerations  prevented  him  from 
carrying  out  the  enterprise. 

The  history  of    the  successful   establishment  of   the  observatory,  in 
connection  with  the  geological  survey,  will  presently  be  given  in  full.

Signal  Service  Occupation.  Mt.  Washington  has  been  occupied  as  one 
of  the  stations  of  the  signal  service  since  its  abandonment  by  the  geolog 
ical  survey,  in  May,  1871.  Sergeant  T.  Smith  was  relieved  by  Sergeant 
M.  L.  Hearne,  in  June,  1871.  Sergeant  Hearne  was  assisted  by  private 
William  Stevens,  till  his  death,  Feb.  22,  1872, — his  place  being  taken  by 
Robert  J.  Bell.  They  arranged  a  box  like  a  chimney,  extending  above 
the  ridge-pole,  so  that  they  could  climb  up  and  expose  the  anemometer 
without  going  out  of  doors  themselves.  The  head  is  protruded  a  single 
instant,  in  order  to  place  the  instrument  properly;  and  the  sensation

hour,  is  said  "to  be  the  same  as  if  a  bucket  of  water  were  thrown  sud 
denly  into  the  face,  and  immediately  frozen  thereon." 

November  14,  15,  and  16,  1871,  are  reported  by  Sergeant  Hearne  as  very 
"stirring  times,"  his  instrument  recording  the  most  rapid  movements  of 
air  ever  described.  At  9  A.  M.,  Nov.  14,  the  wind  blew  at  the  rate  of  40 
miles  to  the  hour.  At  4  p.  M.,  it  reached  60 ;  at  midnight,  78,  and  still 
increasing,  with  snow  and  sleet, — the  barometer  sinking  four  tenths  of 
an  inch  during  the  night.  At  6  A.  M.,  the  I5th,  the  wind  tore  off  five  or 
six  planks  from  a  corner  of  the  building.  At  7,  the  rate  of  velocity  was 
102;  at  9,  120;  at  3  P.  M.,  136  miles.  The  building  cracked,  shook,  and 
groaned  to  its  very  foundation.  At  4  P.  M.,  it  blew  at  a  steady  rate  of  140 
miles,  and  three  more  planks  gave  way.  At  5  p.  M.,  two  trials  gave  150 
and  1 5 1  miles  per  hour.  This  was  the  culmination  of  the  storm,  and  the 
wind  gradually  died  away  during  the  i6th  inst.  Meteorology  does  not  yet 
furnish  the  record  of  a  more  fearful  storm  than  this  experienced  by 
civilized  beings. 

Sergeant  A.  R.  Hornett  succeeded  Hearne,  and  has  already  spent  two 
winters  on  the  summit,  assisted  by  Sergeant  Wm.  Line,  Fred.  DeRoshers, 
and  others.  The  party  now  consists  of  three  persons.  In  1873,  a  build 
ing  was  erected  for  the  occupation  of  the  government  party.  It  is 
situated  a  few  rods  south  of  the  hotel,  in  a  very  exposed  situation.  It  is 
thirty-six  feet  long,  and  twenty-four  wide,  containing  an  office,  dining-, 
store-,  and  two  bedrooms,  besides  an  attic.  It  is  built  of  wood,  and  is 
situated  so  that  the  grandest  views  can  be  seen  without  leaving  a  com 
fortably  warmed  apartment. 

THE  OCCUPATION  OF  MOOSILAUKE — WINTER  OF  1869-70. 

With  the  commencement  of  work  on  the  geological  survey  of  the  state 
in  1869,  this  subject  of  an  elevated  winter  observatory  was  early  dis 
cussed,  Mr.  Huntington  being  prepared  to  occupy  the  position  of 
observer.  But  it  was  found  that  the  lessee  of  the  houses  on  the  summit 
of  Mt.  Washington  was  unwilling  that  they  should  be  occupied  for  this 
purpose  during  the  winter.  While  this  unexpected  refusal  deferred  the 
occupation  of  Mt.  Washington,  it  led  to  a  successful  attempt  in  a  dif 
ferent  direction.  Had  the  observatory  been  established  in  1869,  it  might 
have  been  a  failure,  from  the  want  of  an  experience  of  the  peculiarities 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS.  93 

of  mountain  atmospheric  phenomena.  The  defeat  of  our  plans  coming  to 
the  knowledge  of  Mr.  William  Little,  of  Manchester,  the  owner  of  the 
house  on  the  top  of  Moosilauke,  he  generously  offered  its  free  use  for 
the  occupation  of  Mr.  Huntington's  party  that  winter.  The  proposal 
being  made  to  Mr.  Huntington,  he  adopted  it  without  hesitation, 
although,  in  consequence  of  bad  chirography,  "Moosilauke"  was  mis 
taken  for  "  Monadnock."  Moosilauke,  situated  in  Benton,  is  some  twelve 
or  fifteen  miles  distant  from  the  Franconia  range,  and  in  a  fully  exposed 
position,  being  nearly  five  thousand  feet  high,  and  within  the  Arctic  zone 
of  climate. 

It  was  late  autumn  before  any  preparations  were  made.  Wood  and 
provisions  had  to  be  hauled  up  a  mountain  bridle-path  more  than  a  mile ; 
and  it  was  necessary  to  fit  up  a  comfortable  room.  On  the  230!  of 
November,  an  ascent,  to  make  these  preparations,  was  attempted.  The 
day  was  unfavorable ;  and,  upon  reaching  the  bald  portion  of  the  moun 
tain,  nearly  a  mile  from  the  house  on  the  summit,  the  party  were  met  by 
such  a  furious  storm  of  wind  and  driving  snow  that  they  were  obliged  to 
retreat.  The  following  day,  however,  the  attempt  was  successful ;  and 
three  days  were  spent  in  arranging  for  winter  quarters.  On  the  last  day 
of  December,  Mr.  Huntington  finally  ascended  the  mountain,  to  remain 
for  two  months,  accompanied  by  Mr.  A.  F.  Clough,  photographer,  of 
Warren,  whose  enthusiasm,  backed  by  resolution  and  great  powers  of 
physical  endurance,  proved  of  the  greatest  value,  both  in  this  and  the  Mt. 
Washington  expedition.  The  limited  supply  of  provisions  which  had 
been  taken  up  necessitated  a  short  stay ;  and  the  descent  from  the  moun 
tain  was  made  on  the  last  day  of  February.  It  may  be  proper  to  add 
that  the  whole  expense  of  this  expedition  was  borne  by  those  who  par 
ticipated  in  it,  chiefly  by  Mr.  Huntington. 

By  the  two  months  spent  on  this  summit,  the  possibility  of  living  on  a 
mountain  top  during  the  winter  was  fully  demonstrated.  The  observa 
tions  made  were  published  in  the  newspapers ;  and  the  public  were,  to 
some  extent,  prepared  for  the  expedition  of  the  ensuing  winter,  for  which 
ways  and  means  began  to  be  early  devised. 

The  following  extract  will  be  read  with  the  greater  interest,  since  the 
author — though  the  strongest,  on  both  mountains — has  been  the  first  to 
yield  to  the  attacks  of  disease.  He  died  of  gangrene  on  the  lungs,  in  1 872.

EXTRACTS   FROM  THE   DIARY   OF  A.  F.  CLOUGII,  KEPT  UPON   THE  SUM 
MIT    OF   MOOSILAUKE    IN    1 870. 

January  27.  Mounted  my  snow-shoes,  took  an  axe  and  an  old  iron  tea-kettle,  and 
started  for  Jobildunk  ravine.  Splendid  view  there, — ice  columns  a  hundred  feet  high. 
What  a  time  I  had  getting  down  to  the  foot !  First,  I  sent  the  axe  down  on  a  voyage 
of  discovery,  and  to  bush  out  a  path.  How  it  leaped  and  slid  and  plunged,  as  it  went 
down  to  the  woods  a  thousand  feet  below !  Next  went  the  snow-shoes  ;  but  the  kettle 
would  be  smashed,  and  I  kept  it  along  with  me.  Then  I  slid  a  little  way ;  clinging  by 
the  bushes  and  holding  to  a  birch,  got  clown  a  perpendicular  descent  some  ten  feet. 
From  this  I  could  not  get  back  at  all,  or  down,  except  by  jumping.  Then  I  sent  the 
tea-kettle  ahead.  It  went  leaping  and  whirling  twenty  feet  at  a  bound,  smashed  in 
pieces,  and  was  lost  in  the  firs.  I  never  saw  it  again.  I  looked  over  the  precipice. 
There  was  a  shelf  of  the  rock  twenty  feet  below,  and  a  snow-bank  on  it.  It  was  the 
only  way.  I  jumped,  and  settled  to  my  knees  in  it.  The  rest  of  the  way  was  easier ; 
and,  sliding  and  jumping,  I  was  at  the  foot  in  almost  no  time.  It  was  a  wild,  grand 
scene,  ice  precipices  rising  one  above  the  other  a  thousand  feet,  till  the  tops  are  lost  in 
the  clouds.  Spotted  my  views  ;  and  was  two  hours  climbing  home  through  the  woods. 
The  ravine  is  one  of  the  wildest  places  in  New  Hampshire,  especially  in  winter.  The 
Asquamchumauke  comes  down  through  it. 

February  18.  Storms.  Well,  I  like  a  storm  ;  it  arouses  peculiar  feelings,  excitement, 
when  it  goes  in  strong,  and  it  does  that  to-day,  sure.  One  incessant  roar  all  day,  driv 
ing  sleet  and  rain.  The  house  shakes  and  trembles,  though  one  side  is  buried  in  a  snow 
drift  to  the  top  of  the  roof,  nearly,  with  five  inches  of  snow  and  ice  on  the  roof  and 
walls. 

10  A.  M.  Went  out  with  the  anemometer.  We  had  a  barrel  set  for  the  purpose  ;  but 
the  snow  and  ice  had  filled  it  up,  so  I  held  the  machine  for  ten  minutes.  Sat  down, 
back  to  the  wind,  astride  of  the  barrel.  It  was  no  boy's  play.  Machine  won't  weigh 
five  pounds,  but  it  tired  me  terribly.  The  wind  would  ease  a  trifle,  then  come  with  a 
rush  and  a  roar  louder  than  thunder,  that  made  me  cling,  legs  and  arms,  to  the  barrel. 
The  roar  was  deafening; — I  could  not  hear.  Huntington  gave  signal  with  his  hand, 
and  I  made  for  the  house ;  was  thrown  flat  down  by  the  wind,  then  crept  in.  How 
queer  I  felt.  I  reeled  and  staggered  like  a  drunken  man.  My  head  was  giddy,  my 
eyes  on  fire,  a  thrill  like  electricity  shot  through  my  whole  body,  making  me  wild  and 
reckless.  How  it  would  have  operated  had  I  stopped  longer,  I  cannot  say.  I  should 
be  careless  of  my  life  to  try  it  again.  The  wind  is  blowing  a  hundred  miles  an  hour; 
the  sleet  cuts  like  a  knife  ;  and  my  skin  smarts  wherever  it  was  struck. 

Blows  like  great  guns  this  afternoon.  Rain  comes  down  a  perfect  shower ;  runs  in 
streams  about  our  window.  We  have  got  pails,  buckets,  kettles,  &c.,  to  catch  it,  and 
keep  from  being  drowned  out.  This  is  worse  than  the  storm  of  January  2  ;  but  we  are 
better  prepared  to  meet  it. 


EXPLORATIONS    AMONG   THE    WHITE    MOUNTAINS.  95 

8  P.  M.  No  abatement  in  the  storm  yet.     Blow,  blow!     I  like  it;  it  is  like  a  roar  of 
thunder  all  the  time. 


Fig.   II. — MEASURING  THE   WIND. 

Velocity  88  miles  per  hour. 

10 : 30  P.  M.  Still  continues.  Wind  howls  now  like  ten  thousand  fiends  let  loose 
from  the  infernal  regions. 

February  19.  Well,  the  storm  has  spent  its  fury  at  last.  The  wild,  deafening  roar 
has  died  away,  but  occasional  gusts  sweep  along,  sighing  with  a  low  moan,  the  last 
dying  throes  of  the  wild,  terrifying  hurricane.  It  began  to  abate  last  midnight.  Would 
like  to  have  the  clouds  lift  a  few  minutes,  to  see  how  it  served  people  down  on  earth. 
Huntington  has  gone  down,  and  when  he  comes  back  he  will  report. 

It  takes  a  blow  from  the  south-east  to  get  up  a  storm  and  to  keep  it  going.  It  also 
takes  a  blow  from  the  north-west,  up  in  this  altitude,  a  mile  above  the  ocean,  to  clear  it 
off.  It  is  cold  to-day. 

This  afternoon  we  got  frost  clouds, — "clouds  made  up  of  minute  particles  of  ice, 
said  to  bring  death  to  any  one  caught  in  them."  That  story  is  a  myth.  [See  page 
86.]  We  found  them  as  harmless  as  a  summer  vapor. 

February  20.  Thermometer  14°  below ;  clear  and  pleasant.  Looked  away  to  the 
south-east,  and  saiv  the  ocean.  Walked  down  to  the  ravine  ;  got  a  fall,  and  slid  down 
a  hundred  feet ;  brought  up  in  a  snow-bank  ;  was  frightened,  but  not  hurt  a  bit.  Hack 
matacks  are  buried  in  snow.  Wind  has  changed  to  south-east  again ;  another  storm  is 
on  the  stocks. 

2.  p.  M.  It  is  blowing  again, — it  roars  again, — it  howls  again.     I  thought  the  wind 


96 


PHYSICAL    GEOGRAPHY. 


had  blown  as  hard  as  it  could,  but  it  is  now  worse  than  ever  before.  I  shall  not  wet 
myself  to  the  skin  again  to  hold  up  that  anemometer.  I  know  it  blows  at  the  rate  of 
more  than  a  hundred  miles  an  hour.  How  it  roars!  But  "roar"  doesn't  express  the 
noise  ;  bellow  is  too  tame  by  half.  In  a  thunder-storm  the  lightning  flashes,  blinding 
the  sight;  then  comes  a  sharp  report,  which  immediately  gives  way  to  deep,  reverbera- 
tory  rumbling  that  shakes  and  makes  everything  vibrate  with  its  power,  then  rolls  away 
and  is  lost.  Now  just  imagine,  if  you  can,  a  continual  roll  of  the  first  reverberations, 
after  the  sharp  report  is  over,  and  you  will  have  some  faint  idea  of  what  we  have  this 
day, — a  continual  thunder,  making  everything  shake  for  hours  together.  Have  storms 
like  this  swept  over  these  mountains  for  thousands,  perhaps  millions,  of  years?  or,  is 
this  a  special  storm  for  the  benefit  of  us  two  poor  mortals  who  have  invaded  this  bleak 
and  lofty  region?  Can't  tell. 

February  21.  Snows;  and  there  is  a  drift  fifteen  feet  high  on  the  south  side  of  our 
house.  Had  to  shovel  out  our  window  to  let  in  daylight. 

i  p.  M.  I  am  writing  by  lamplight ; — the  house  is  completely  snowed  up. 

February  22.  Thermometer  17°  below.     House  still  snowed  up  ; — time  drags. 

THE  Mr.  WASHINGTON  EXPEDITION — WINTER  OF  1870-71. 

This  expedition,  like  that  upon  Moosilauke,  was  undertaken  for  the 
purpose  of  contributing  something  to  the  solution  of  the  great  question 
whether  science  can  forecast  the  weather  for  hours  and  days  beforehand. 
It  was  deemed  especially  important  to  investigate  the  meteorology  of  Mt. 
Washington, — the  highest  point  of  land  in  the  eastern  United  States, — 
as,  from  its  exposed  position,  it  might  be  expected  to  give  the  first  indica 
tions  of  approaching  storms.  The  observations  upon  Moosilauke  had 
afforded  valuable  experience  for  this  more  extended  expedition,  and  had 
already  given  some  indication  of  the  phenomena  peculiar  to  the  higher 
New  England  summits  in  winter.  As  nothing  of  this  kind  was  contem 
plated  in  the  original  act  establishing  the  geological  survey  of  the  state, 
it  was  not  possible,  nor  desired,  to  use  any  of  the  funds  appropriated  to 
geological  exploration  for  meteorological  purposes.  With  the  approval  of 
the  state  authorities,  the  geological  survey  adopted  the  expedition  as  a 
part  of  its  work,  and  obtained  the  requisite  funds  entirely  by  subscription. 
The  total  amount  expended,  including  the  value  of  materials  and  other 
substantial  aid  furnished,  reached  as  high  as  $3,500. 

In  the  preparations  for  this  expedition  a  house  was,  of  course,  the  first 
essential.  Application  was  again  made  for  the  Tip-top  house  :  this  was 
met  by  a  courteous  but  firm  refusal.  At  one  time  the  question  of  build- 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS.  97 

ing  a  small  house  was  discussed.  From  his  elevated  observatory  on 
Moosilauke,  Mr.  Hunting-ton,  by  letter  of  February  iSth,  1870,  had  pro 
posed  that  negotiations  be  commenced  with  the  Mt.  Washington  Railway 
Company  for  the  use  of  the  engine-house  or  depot  they  were  intending 
to  build  on  the  summit.  After  the  adverse  decision  in  regard  to  the  Tip 
top  house,  a  letter  was  addressed  to  Mr.  Sylvester  Marsh,  the  president 
of  this  company,  inquiring  whether  their  building  might  not  be  used  in 
the  winter  by  the  meteorological  party.  In  reply,  it  was  stated  that  the 
completion  of  the  house  before  winter  was  uncertain  ;  but  a  desire  was 
expressed  that  the  project  might  be  successful.  Interviews  were  had 
with  Mr.  Marsh,  and  he  spoke  even  more  favorably  than  had  been 
expected  from  his  letter ;  but  he  added,  that  he  had  not  the  authority  to 
speak  for  the  company.  Having  no  reason  to  suppose  the  directors 
would  not  favor  us,  late  in  July  the  state  geologist  issued  a  circular, 
stating  the  importance  of  establishing  a  meteorological  observatory  upon 
Mt.  Washington  in  the  winter,  and  asked  the  friends  of  science  to  con 
tribute  the  sum  of  two  thousand  dollars  to  maintain  the  expedition,  and 
furnish  the  means  of  telegraphic  communication  between  the  observers 
and  the  public.  It  was  stated  that  with  this  sum  the  expedition  could  be 
made  successful,  and  the  public  would  receive  daily  reports  describing 
the  character  of  the  arctic  phenomena  peculiar  to  the  summit,  thus  giving 
abundant  opportunity  for  comparison  with  any  observatory  in  the  country. 
This  circular  was  sent  to  friends,  and  small  sums  were  received,  but  not 
to  any  promising  extent.  It  was  also  posted  at  the  principal  hotels  among 
the  mountains,  in  full  view  of  the  guests,  but  failed  to  excite  any  special 
interest.  The  remainder  of  the  summer  was  so  occupied  with  necessary 
geological  field-work  as  to  leave  no  time  to  beg  for  money. 

By  the  first  of  September  not  a  hundred  dollars  had  been  promised. 
The  next  effort  was  in  the  direction  of  the  press.  A  prominent  journal 
in  New  York  was  willing  to  give  five  hundred  dollars  for  daily  telegrams 
and  occasional  letters  sent  to  them  exclusively  during  the  winter. 
Although  a  telegraph  line,  capable  of  use  in  the  winter  months,  was 
beyond  the  expected  means,  faith  in  ultimate  success  was  strengthened 
by  this  proposal.  About  this  time  attention  was  called  to  the  recent 
establishment  of  the  "  Bureau  of  Telegrams  and  Reports  for  the  Benefit 
of  Commerce,"  in  connection  with  the  War  department  at  Washington. 
VOL.  i.  13 


98  PHYSICAL    GEOGRAPHY. 

Application  was  made  to  Gen.  A.  J.  Myer,  the  chief  signal  officer,  for 
funds  to  aid  in  carrying  out  this  enterprise,  allowing  the  weather  office 
to  share  its  benefits.  The  answer,  dated  September  I4th,  stated  that  the 
chief  signal  officer  could  "hardly  appropriate  money  for  the  object  named  ; 
but  it  may  be  in  the  power  of  this  office,  with  the  approval  of  the  secre 
tary  of  war,  to  detail  an  observer  for  the  position  you  propose  to  occupy." 
In  further  correspondence,  he  stated  his  willingness  to  provide  an  insu 
lated  telegraph  wire,  to  extend  from  the  summit  of  Mt.  Washington  to 
the  railroad  station  at  its  base;  adding,  however,  that  he  could  not  sanc 
tion  any  special  arrangement  to  furnish  any  one  paper  exclusively  with 
the  weather  reports.  He  proposed  himself  to  furnish  weather  reports 
from  all  the  stations  throughout  the  country  to  the  principal  newspapers, 
as  well  as  to  the  chambers  of  commerce.  He  also  offered  to  provide  the 
meteorological  instruments  required  for  the  station.  Thus  the  means 
were  provided  for  sending  daily  telegrams,  but  it  necessitated  a  change 
from  the  proposal  to  send  the  weather  reports  exclusively  to  the  New 
York  Tribune,  and  left  the  enterprise  as  poor  as  ever. 

In  a  letter  of  October  7th,  the  chief  signal  officer  announced  that  he 
had  sent  to  the  state  geologist  three  miles  of  insulated  Kerite  telegraph 
wire,  two  telegraph  instruments,  two  sections,  and  four  conductors,  to 
the  value  of  $1,032  ;  and  that  an  instructed  observer  would  probably  be 
detailed  to  join  the  expedition.  These  telegraph  supplies  were  duly 
received,  and  immediately  transported  to  the  mountain. 

From  another  quarter,  however,  there  came  the  required  pecuniary 
assistance.  In  the  month  of  July,  the  state  geologist  learned  that  Mr. 
S.  A.  Nelson,  of  Georgetown,  Mass.,  was  very  much  interested  in  the 
meteorology  of  Mt.  Washington,  and  would  like  to  join  the  expedition. 
He  soon  after  received  a  letter  from  Mr.  Nelson,  presenting  this  request, 
and  asking  also  for  further  information.  His  tone  of  writing  evinced  a 
rare  enthusiasm  for  the  undertaking,  and  from  further  correspondence  it 
appeared  that  he  was  ready  to  devote  himself  to  raising  funds  for  the 
expedition,  in  case  he  could  be  one  of  the  party.  A  formal  invitation  was 
soon  extended  to  Mr.  Nelson,  which  he  accepted,  and  immediately  set 
himself  to  the  task  of  soliciting  subscriptions  in  eastern  Massachusetts, 
pledging  himself  to  procure  at  least  $500.  His  promise  was  more  than 
realized,  for  his  efforts  brought  in  more  than  $800.  His  labors  com- 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.  99 

mcncccl  early  in  September,  and  he  did  not  go  upon  the  mountain  till 
late  in  December,  remaining  behind  after  the  occupation  of  the  summit 
to  complete  what  he  conceived  to  be  his  part  of  the  work  below. 

It  became  evident  that  the  public  were  slowly  gaining  confidence  in 
the  success  of  our  enterprise,  and  therefore  we  began  to  purchase  our 
supplies.  Mr.  Huntington  made  out  the  list,  that  the  needed  articles 
might  be  at  the  lower  mountain  depot  early  in  October,  understanding 
that  the  trains  could  not  transport  freight  for  the  expedition  before  that 
time.  On  the  I9th  of  September,  however,  information  accidentally  came 
to  the  state  geologist,  at  Bethlehem,  that  the  mountain  trains  would  stop 
running  on  the  following  day,  as  the  track  was  to  be  taken  up  immediately 
for  repairs;  and  that  no  orders  had  been  given  by  the  officers  of  the 
company  to  afford  the  expedition  any  facilities,  either  of  transportation 
or  the  use  of  the  summit  depot.  To  add  to  these  difficulties,  the  supplies 
had  not  all  been  purchased.  It  was  uncertain  whether  sufficient  funds 
could  be  obtained ;  and  no  arrangement  had  then  been  made  for  the  use  of 
a  telegraph  cable.  Under  these  unpromising  circumstances,  the  party  at 
Bethlehem,  with  the  exception  of  the  state  geologist,  came  unanimously 
to  the  conclusion  that  the  difficulties  in  the  way  were  insurmountable,  and 
that  the  expedition  must  be  abandoned  for  the  next  winter.  But  he  said 
that  the  supplies  should  all  go  up  the  mountain,  even  if  he  turned  team 
ster  himself,  and,  with  a  single  horse,  transported  them  up  the  carriage- 
road, — Mr.  Huntington  having  expressed  a  willingness  to  remain  upon  the 
summit  all  winter,  even  without  telegraphic  communication  with  the 
world  below.  The  next  day,  therefore,  one  of  the  party  went  to  the 
railroad  station  to  say  that  orders  were  coming  from  head-quarters  to 
grant  the  needed  facilities,  as  they  must  have  been  delayed  by  some  mis 
understanding.  Another  went  to  Littleton  to  borrow  a  few  tons  of  coal, 
that  the  most  essential  article  to  comfort  might  be  sure  to  reach  the 
railroad  in  season  for  transportation  to  the  summit.  Prof.  Hitchcock,  at 
the  same  time,  went  to  Boston,  and  obtained  from  the  officers  of  the 
company  the  necessary  permission  to  use  their  summit  depot  during  the 
winter,  and  immediately  transmitted  it  to  the  employes.  The  railway

have  been  completed.  The  necessary  supplies  were  immediately  pur 
chased,  and  transported  without  charge  from  Boston  to  the  Wing  road, 
by  the  B.  L.  &  N.,  Concord,  and  B.  C.  &  M.  railroads.  After  all  our 
efforts,  however,  the  telegraphic  apparatus  sent  from  Washington,  and 
some  other  necessary  articles,  arrived  too  late  for  the  last  train ;  and  these 
were  taken  around  the  mountain, — partly  by  Prof.  Hitchcock  and  partly 
by  Mr.  Huntington, — and  thence  to  the  summit,  on  the  carriage-road. 
The  distance  traversed  was  nearly  eighty  miles,  over  a  very  muddy  and 
hilly  route — a  tedious  journey,  whose  difficulties  can  never  be  appreciated 
by  the  public.  Several  days  were  spent  upon  the  summit  in  preparing 
the  building  for  occupation, — partitioning  off  a  room,  laying  double  floors, 
setting  up  the  stoves,  etc.  Mr.  Huntington  remained  upon  the  mountain 
till  the  rooms  were  completed  for  occupation,  the  Kerite  wire  laid,  and

everything  in  readiness  for  the  incoming  of  the  party.     He  came  down 
October  22. 

A  new  circular,  adapted  to  the  changed  circumstances,  was  now  pre 
pared  and  widely  distributed.  In  this  it  was  briefly  stated  that  the 
arrangements  for  the  occupation  of  the  mountain  had  been  completed  ; 
the  observers,  photographers,  and  telegrapher,  selected;  the  needful

supplies  purchased  and  transported  to  the  summit;  a  Kerite  telegraph 
wire  had  been  laid  over  that  portion  of  the  route  where  a  common  wire 
could  not  withstand  the  wintry  blasts  and  accumulations  of  ice ;  that  the 
building  had  been  secured  and  comfortably  furnished ;  and,  furthermore, 
that  the  party  intended  to  establish  themselves  in  their  snug  eyrie  about 
the  1 2th  of  November.  Reference  was  made  to  the  approval  of  the 
expedition  by  the  War  department,  and  to  a  special  letter  of  recommenda 
tion  signed  by  Professors  B.  Pierce,  Joseph  Winlock,  Joseph  Lovering, 
Asa  Gray,  Alpheus  Hyatt,  President  Runkle,  N.  B.  Shurtleff,  and  William 
Claflin.  It  was  thought  that  commerce  would  be  greatly  benefited  by 
the  daily  reports.  As  the  farmer  studies  the  cloud-caps  upon  mountains 
to  forecast  the  weather,  so  telegraphic  reports  of  the  condition  of  the 
atmosphere  upon  the  highest  summit  in  eastern  America  would  enable 
ship-owners  to  judge  of  the  approach  of  storms,  and  escape  risk  of  loss 
to  their  vessels  by  keeping  them  in  a  harbor  until  the  danger  was  past ; 
so,  too,  with  fair  weather  reported  from  the  mountain,  vessels  could  get 
a  day's  start  of  any  bad  spell  of  weather,  and  thus  escape  great  peril. 
It  was  announced  that  the  preparations  for  the  expedition  had  been  made 
with  the  expectation  that  friends  would  contribute  funds  sufficient  to 
meet  the  expenses.  Should  the  public  fail  to  appreciate  the  enterprise, 
the  burden  would  fall  upon  the  state  geologist,  who  had  already  paid  out 
$700  more  than  the  amount  of  the  subscriptions.  This  appeal  proved  to 
be  efHcacious,  as,  in  consequence  of  this  and  other  applications,  enough 
funds  were  at  length  secured  to  meet  all  the  expenses  of  the  expedition. 

On  the  3d  of  October,  a  letter  was  received  from  Mr.  H.  A.  Kimball, 
photographer,  of  Concord,  N.  H.,  asking  to  be  permitted  to  join  the 
party  and  take  views.  According  to  the  original  plan,  the  artist  of  the 
expedition  was  Mr.  A.  F.  Clough,  who  had  been  associated  with  Mr. 
Huntington  in  the  occupation  of  Moosilauke ;  hence  this  application  was 
referred  to  him,  with  the  result  that  the  two  gentlemen  concluded  to 
combine  their  efforts,  and  go  upon  the  mountain  in  company.  Mr.  Kim- 
ball  aided,  also,  in  the  work  of  raising  funds,  adding  more  than  a  hundred 
dollars  to  the  list.  Both  the  photographers  made  personal  pecuniary 
sacrifices  to  render  their  branch  of  the  expedition  successful ;  and  their 
published  stereographs  have  proved  a  valuable  addition  to  its  records. 

On  the   third  of   November,  the  chief   signal  officer  informed   Prof. 


IO2  PHYSICAL    GEOGRAPHY. 

Hitchcock  that  he  would  send  an  instructed  operator  and  observer,  with 
a  complete  set  of  meteorological  instruments,  to  Mt.  Washington,  and 
requested  that  one  weather  report  might  be  forwarded  to  him  daily  by 
telegraph.  This  report  would  be  bulletined  along  with  those  from  other 
stations,  and  a  copy  of  it  furnished  to  the  principal  daily  journals  in  the 
country.  After  some  delay,  Sergeant  Theodore  Smith,  U.  S.  A.,  started 
from  Washington,  and  reached  the  mountain  early  in  December. 

The  complete  organization  of  the  expedition  was  as  follows : 

C.  H.  HITCHCOCK,  state  geologist,  with  office  in  Hanover  connected  by 
telegraph  with  the  summit  of  Mt.  Washington. 

J.  H.  HUNTINGTON,  assistant  state  geologist,  in  charge  of  the  observ 
atory  upon  the  mountain. 

S.  A.  NELSON,  observer. 

A.  F.  CLOUGH  and  H.  A.  KIMBALL,  photographers. 

THEODORE  SMITH,  observer  and  telegrapher  for  the  signal  service. 

The  mountain  was  occupied  for  scientific  observation  during  a  period 
of  six  months,  from  Nov.  12,  1870,  to  May  12,  1871.  From  that  time  to 
the  present,  the  observations  have  been  continued  by  the  United  States 
signal  service,  this  being  adopted  as  one  of  their  regular  stations. 

NARRATIVE  OF  THE  EXPEDITION. 

The  meteorological  records  of  the  expedition  have  been  made  the  sub 
ject  of  a  separate  portion  of  this  work.  It  has  been  thought,  also,  that, 
in  addition  to  these,  some  account  of  the  doings  and  experiences  of  the 
party  while  on  the  summit  would  be  sought  for  in  these  pages.  Extracts 
from  the  journal  of  the  expedition,  kept  by  Mr.  Huntington,  from  Nov. 
12  to  Dec.  20,  and  subsequently  by  Mr.  Nelson,  together  with  its  history 
from  the  beginning,  and  a  statement  of  its  results,  were  in  due  time 
arranged  and  published.*  All  who  were  connected  with  the  expedition 
contributed  to  this  work,  which  was  "addressed,  as  their  official  report,  to 
those  friends  who  furnished  the  means  of  establishing  this  Arctic  observ 
atory."  Portions  have  been  selected  from  this  work  for  presentation 
here,  so  far  as  to  show  some  of  the  most  noteworthy  experiences  of  a 
life  in  winter  upon  Mt.  Washington.

Mr.  L.  L.  Holclen,  correspondent  of  the  Boston  Journal,  visited  the 
mountain  February  8,  and  again  April  29.  He  describes  the  quarters 
occupied  by  the  party  as  follows : 

The  depot  was  built  last  summer,  and  occupies  a  site  of  the  same  elevation  as  the 
Tip-top  and  Summit  houses,  north-easterly  of  those  structures,  upon  the  verge  of  the 
little  plateau  forming  the  summit  of  the  mountain.  The  building,  unlike  the  two 
diminutive  public  houses,  whose  sides  are  of  stone,  is  constructed  wholly  of  wood.  It 
is  sixty  feet  long  by  twenty-two  feet  wide,  and  stands  nearly  north  and  south.  It  has 
eleven  feet  posts,  and  the  elevation  of  the  ridge-pole  is  twenty-five  feet,  the  roof  being 
of  the  same  form  as  the  roofs  of  ordinary  buildings.  The  apartment  inhabited  by  the 
party  is  situated  in  the  south-east  corner  of  this  edifice.  It  is  a  room  about  twenty  feet 


Fig.  13. — THE   HOME   OF   THE   EXPEDITION. 

long,  eleven  feet  wide,  and  eight  feet  high.  The  larger  portion  of  the  depot  forms  a 
sort  of  vestibule  to  this  room,  and  is  wholly  enclosed,  except  at  the  easterly  end  of  the 
northern  face,  where  the  outer  door  is  situated.  The  little  room  was  formed  in  the 
following  manner :  i ,  there  was  the  thick  plank  floor  of  the  depot  itself,  which  con 
stituted  a  good  foundation  to  build  upon ;  2,  a  course  of  sheathing  paper  was  laid  over 
the  original  floor ;  3,  an  additional  floor  of  close-fitting  boards  was  then  laid  down ; 
4,  two  thicknesses  of  sheathing  paper  were  placed  on  the  top  of  the  second  floor ;  5,  a 
layer  of  carpet  lining  was  added ;  and  6,  a  thick  woollen  carpet  was  made  the  upper 
most  layer  of  all.  The  inside  of  the  outer  walls  was  covered  first  with  tarred  paper, 


104  PHYSICAL    GEOGRAPHY. 

then  with  boards ;  a  layer  of  sheathing  paper  was  added,  and  wall  paper  spread 
upon  this.  The  ceiling  is  formed  of  two  thicknesses  of  boards  with  sheathing  paper 
between,  and  the  inner  walls  consist  of  single  thicknesses  of  boards,  sheathing  paper, 
and  wall  paper.  There  are  two  double  windows,  or  rather  half-windows,  on  the  westerly 
side  of  the  room,  and  these  are  protected  by  strips  of  board  without.  The  door  of 
the  room  is  of  ordinary  size,  but  the  outer  door  is  nothing  but  a  little  opening  two  feet 
square,  some  two  feet  from  the  floor. 

We  have  thus  far  described  none  of  the  precautions  taken  to  prevent  the  building 
from  being  torn  to  pieces  by  the  terrible  winter  tempests,  or  from  being  blown  away 
altogether.  The  frame-work  is  of  the  strongest  possible  kind,  and  is  fitted  together  in 
the  best  manner.  The  sills  extend  beyond  the  walls  eight  or  ten  feet,  and  every  means 
are  taken  to  fasten  the  structure  down  to  its  rocky  base.  Within,  bolts,  iron  rods,  and 
wooden  braces  add  strength  to  the  walls,  and  three  strong  iron  chains,  securely  fastened 
to  the  rocks,  pass  over  the  roof.  Notwithstanding  all  these  provisions,  the  building 
rocks  and  bends  before  a  furious  wind-storm  in  a  manner  well  calculated  to  create 
consternation  and  dismay.  An  ordinary  house  would  stand  no  longer  before  such  terrific 
blasts  than  would  a  house  of  cards  before  an  ordinary  wind.  The  great  gale  in  Decem 
ber  awakened  the  fears  of  the  party  for  the  safety  of  the  depot,  but,  as  the  structure 
stood  that  frightful  assault,  it  was  thought  no  further  danger  on  that  score  need  be 
apprehended.  It  was  nevertheless  thought  best  to  strengthen  the  walls  with  addi 
tional  braces  and  supports. 

The  work  of  the  expedition  was  begun  by  Mr.  Huntington,  who 
ascended  November  12,  and  was  for  nearly  three  weeks  alone  upon  the 
mountain.  We  copy  from  his  journal : 

November  12.  Started  from  Marshficld  at  7  A.  u. ;  arrived  at  the  summit  of  Mt. 
Washington  at  9:30.  It  rained  until  I  got  within  three  fourths  of  a  mile  of  the  sum 
mit  ;  then  there  was  a  frozen  mist.  The  snow  was  six  inches  deep  at  Ammonoosuc  ;  at 
Waumbek  Junction,  a  foot.  At  the  second  tank  the  snow  was  drifted  ;  none  on  the 
ties  above.  On  the  summit  it  was  drifted  so  that  neither  at  the  Summit  nor  the  Tip-top 
house  could  the  doors  be  seen  ;  there  was  very  little  about  the  depot.  I  am  here  alone, 
but  should  have  come  if  I  had  known  that  I  had  to  stay  alone  all  winter. 

November  15.  Have  been  above  the  clouds  all  day  long.  Some  of  the  time  not  a 
single  mountain  top  could  be  seen.  Occasionally  Mts.  Adams  and  Jefferson  would 
appear,  but  most  of  the  day  in  every  direction  was  this  illimitable  sea  of  clouds. 

November  24.  The  barometer  lower  this  morning  than  it  has  been  before.  Wind 
blowing  fiercely  from  the  north-west,  not  steadily,  but  in  gusts.  The  house  creaks  in 
every  joint.  It  is  something  fearful  to  sit  here  alone  and  hear  the  wind  howl,  while 
showers  of  ice  are  blown  against  the  side  of  the  building  and  along  the  roof. 

November  30.  Clear  until  2  p.  M.,  when  light  clouds  began  to  pass  over  the  moun-

tain,  but  became  dense  toward  night.  Was  surprised  by  the  arrival  of  Clough,  Kimball, 
Cheney,  and  Bracy.  I  am  not  likely  to  be  alone  again  this  winter. 

December  4.  Sergeant  Smith  arrived  to-day. 

December  12.  Clough  and  Smith  went  down  to  the  base  of  the  mountain,  and  as 
they  returned  found  that  the  wire  would  work  to  the  second  tank,  but  could  get  no 
current  on  the  summit. 

December  13.  The  telegraph  worked  to-day  for  the  first  time.  Now  we  are  in  the 
xvorld  again. 

The  ascent  of  the  photographers,  Messrs.  Clough  and  Kimball,  accom 
panied  by  two  friends, — Charles  B.  Cheney,  of  Orford,  and  C.  F.  Bracy, 
of  Warren, — upon  Nov.  30,  was  accomplished  under  circumstances  of 
great  difficulty.  The  party  had  been  delayed  in  reaching  Ammo- 
noosuc  by  being  unexpectedly  obliged  to  chop  a  passage-way  through 
trees  which  the  wind  had  thrown  across  their  road ;  and  it  was  past  the 
middle  of  the  afternoon  before  they  could  start  on  the  ascent.  But,  as 
the  weather  appeared  propitious,  they  decided  to  advance,  having  been 
already  delayed  several  days  beyond  their  original  plans.  The  following 
description  of  their  experience  was  prepared  by  Mr.  Kimball,  whose 
strength  proved  unequal  to  the  severe  task  when  suddenly  overtaken  by 
one  of  the  fierce  mountain  storms. 

The  end  of  the  first  mile,  carrying  us  up  to  within  one  half  mile  of  the  limit  of  wood- 
growth,  found  us  in  tolerable  condition,  when  a  halt,  for  breath  and  observation, 
discovered  to  us  an  approaching  storm  lying  on  the  Green  Mountains  of  Vermont.  It 
would  undoubtedly  strike  us,  but  we  still  hoped  that  we  might  press  on  and  reach  the 
summit  first.  The  thought  of  being  overtaken  by  a  furious  storm,  on  the  wintry,  shel 
terless  cliffs  of  Mt.  Washington,  with  the  night  about  to  enshroud  us,  was  fearfully 
impressive,  and  prompted  us  to  our  best  endeavors.  With  all  the  effort  we  could 
well  muster,  we  had  only  advanced  a  half  mile  more,  carrying  us  fairly  above  the 
wooded  region  to  the  foot  of  "Jacob's  Ladder,"  when  the  storm  struck  us.  There  were 
suddenly  wrapped  around  us  dense  clouds  of  frozen  vapor,  driven  so  furiously  into  our 
faces  by  the  raging  winds  as  to  threaten  suffocation.  The  cheering  repose  of  the  ele 
ments  but  a  moment  before,  had  now  given  place  to  what  might  well  be  felt  as  the 
power  and  hoarse  rage  of  a  thousand  furies ;  and  the  shroud  of  darkness  that  was  in  a 
moment  thrown  over  us,  was  nearly  equal  to  that  of  the  moonless  night.  Compelled 
to  redoubled  efforts  to  keep  our  feet  and  make  proper  advance,  we  struggled  with  the 
tempest,  though  with  such  odds  against  us  that  we  were  repeatedly  slipping  and  getting 
painful  bruises.  Mr.  Kimball  finding  himself  too  much  exhausted  to  continue  this 
struggle  on  the  track,  we  all  halted  in  brief  consultation.  It  was  suggested  that  we

IO6  PHYSICAL    GEOGRAPHY. 

return  to  Waumbek  station,  an  old  building  a  half  mile  below  us,  and  there  try  to  keep 
ourselves  from  freezing  by  brisk  exercise.  Mr.  Clough  emphatically  vetoed  this  as  a 
most  dangerous  and  impracticable  proposition,  saying  that  our  only  hope  consisted  in 
pushing  upward  with  all  our  might. 

Here  we  became  separated :  three  of  the  party  left  the  track,  and  Mr.  Kimball  will 
ingly  left  behind  his  luggage  in  order  to  continue  the  ascent.  By  thus  leaving  the 
track  we  escaped  liability  to  falls  and  bruises,  but  found  ourselves  often  getting  buried 
to  our  waists  in  snow,  and  forced  to  exert  our  utmost  strength  to  drag  ourselves  out  and 
advance.  We  repeatedly  called  to  Mr.  Bracy,  who  had  kept  on  the  track  as  we  sup 
posed,  but  could  get  no  answer.  The  roar  of  the  tempest  overcame  our  utmost  vocal 
efforts ;  and  the  cloud  of  frozen  vapor,  that  lashed  us  so  furiously  as  it  hugged  us  in  its 
chilling  embrace,  was  so  dense  that  no  object  could  be  seen  at  a  distance  of  ten  paces. 
Against  such  remorseless  blasts,  no  human  being  could  keep  integrity  of  muscle  and 
remain  erect.  We  could  only  go  on  together  a  little  way,  and  then  throw  ourselves  down 
for  a  few  moments  to  recover  breath  and  strength.  We  had  many  times  repeated  this, 
when  Mr.  Kimball  became  so  utterly  exhausted  as  to  make  it  impossible  for  him  to  take 
another  step.  He  called  to  the  others  to  leave  him,  and  save  themselves,  if  possible. 
The  noble  and  emphatic  "Never!'1'1  uttered  by  the  manly  Clough,  whose  sturdy  muscle 
was  found  able  to  back  his  will,  aroused  him  to  another  effort.  The  two  stronger 
gentlemen,  whose  habits  of  life  and  superior  physical  powers  gave  hope  of  deliverance 
for  themselves,  were  both  immovable  in  the  determination  that  our  fate  should  be  one, 
let  that  be  what  it  must. 

The  situation  was  one  of  momentous  peril,  especially  as  to  Mr.  Kimball,  whose 
exhaustion  was  now  so  extreme  that  he  was  wholly  indifferent  to  the  fate  that  seemed 
to  impend,  only  begging  that  he  might  be  left  to  that  sleep  from  whose  embrace  there 
was  left  no  power  of  resistance.  Still  there  was  forced  a  listless  drag  onward,  mostly 
in  the  interests  of  his  companions,  and  in  obedience  to  their  potent  wills.  After  this 
sort  we  struggled  on  a  few  rods  at  a  time,  falling  together,  between  each  effort,  to  rest 
and  gain  new  strength.  With  the  wind  at  70  miles  per  hour,  and  the  thermometer 
down  to  7°, — as  was  found  after  arriving  at  the  observatory, — we  came  at  length  to 
"Lizzie  Bourne's  monument,"  only  thirty  rods  from  the  observatory.  It  took  more 
than  a  half  hour's  time  to  make  this  last  thirty  rods.  Even  the  stronger  ones  had 
become  wearied  by  their  unusual  exertions,  and  had  not  this  been  the  case  their  prog 
ress  would  have  been  slow,  for  it  was  found  absolutely  impossible  to  force  on  the  one 
who  had  now  become  unable  to  regard  his  own  peril,  more  than  a  few  feet  at  a  time. 
He  would  then  sink  down  into  a  deep  sleep,  while  the  others  would  employ  the  time  in 
chafing  his  hands  and  feet,  and,  after  a  few  moments,  manage  to  arouse  him  and  make 
another  struggle  onward. 

Mr.  Bracy,  too,  had  a  narrow  escape.  Losing  his  foothold  on  the  track,  he  at  one 
time  fell  through  into  a  gorge  beneath  the  trestle-work.  Exhausted,  bruised,  and  dis 
couraged,  he  crawled  beneath  the  ruins  of  the  old  "Gulf  house,"  which  were  found  to 
be  at  hand,  thinking  he  would  try  to  weather  the  storm  there  ;  but  finding  himself,  in 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.          IO/ 

spite  of  every  effort,  getting  numb  and  dozy,  he  rallied  to  a  new  struggle,  and  thus 
saved  himself. 

air.  Huntington,  aroused  by  the  arrival  of  Mr.  Bracy,  sallied  out  with  a  lantern  in 
search  of  us,  but  found  his  best  exertions  of  little  avail,  the  storm  being  so  fierce  and 
thick  that  he  could  neither  make  himself  seen  nor  heard  beyond  a  few  paces  ;  and  they 
were  regarding  us  as  probably  lost,  though  preparing  for  another  effort  in  our  behalf, 
when  we  arrived. 

This  was  perhaps  the  most  perilous  ascent  of  the  winter,  owing  to  the 
storm  and  darkness,  especially  as  Mr.  Kimball  had  been  wholly  unaccus 
tomed  to  severe  physical  exertion.  The  ascent,  under  the  greatest  diffi 
culties,  was  that  of  April  5,  by  Messrs.  Clough  and  Cheney.  The  wind 
blew  over  eighty  miles  an  hour,  while  the  temperature  was  nearly  at 
zero.  They  succeeded  in  reaching  the  summit  on  account  of  their  supe 
rior  powers  of  endurance.  Most  persons  would  have  perished.  An 
ascent  has  since  been  made,  however,  by  Mr.  Huntington,  late  in  Novem 
ber,  1873,  under  circumstances  still  more  perilous.  The  temperature  was 
17°  below  zero,  and  the  velocity  of  the  wind  72  miles  per  hour.  It  should 
be  remembered  that,  at  the  same  time  with  such  severity  of  exposure 
upon  the  mountain,  the  weather  at  the  base  may  seem  favorable  for  the 
ascent 

The  expedition  had  an  early  experience  of  the  furious  storms  peculiar 
to  mountain  summits.  Mr.  Huntington  writes  :  "There  was  a  storm  of 
some  severity  the  24th  of  November,  when  I  was  alone  on  the  mountain. 
But  the  most  severe  storm,  of  all  that  we  had,  occurred  on  the  I5th  of 
December,  and,  as  it  was  the  first  terrific  storm  since  the  house  had  been 
built  which  we  occupied,  we  did  not  feel  that  security  that  we  should  in 
one  that  had  stood  the  force  of  the  storms  in  winters  past.  The  other 
houses  are  of  stone;  ours  of  wood, — and,  besides,  presented  a  much 
greater  surface  to  the  wind  than  any  building  ever  before  erected  on  the 
summit.  Two  of  the  party  had  never  been  on  a  mountain  during 
a  winter  storm,  so  they  would  be  likely  to  describe  it  more  vividly  than 
a  person  who  had  witnessed  many," — as  appears  in  the  following,  by 
H.  A.  Kimball : 

We  have  had  probably  as  severe  a  tornado  as  will  visit  us  during  the  winter.  The 
velocity  of  the  wind  was  recorded  at  7  p.  M.,  and  it  was  92  miles  per  hour.  After  that 
time  it  was  not  safe  to  venture  out  with  the  anemometer,  unless  we  wanted  to  take  an

air-line  passage  to  Tucker-man's  ravine,  for  the  wind  kept  increasing  until  towards 
morning,  when  it  blew  a  terrific  hurricane.  Mr.  Huntington  and  Mr.  Clough,  both 
having  had  considerable  of  this  kind  of  experience,  say  it  must  have  blown,  at  the 
highest  point,  no  to  120  miles  per  hour.  We  expected  at  any  moment  to  have  the 
building  come  down  about  our  heads,  and  were  prepared  to  make  an  effort  for  our  lives, 
having  put  hard-tack  in  our  pockets,  and  armed  with  axe  and  saw,  ready,  in  case  we 
found  it  necessary,  to  cut  our  way  out,  getting  also  some  of  our  thickest  blankets  ready 
for  use,  and  preparing  with  considerable  excitement  for  any  emergency.  The  wind 
roared  terribly,  as  if  inspired  with  the  power  and  spite  of  all  the  furies,  and  the  wild 
rage  was  so  deafening  that  we  were  obliged  to  shout  to  our  utmost  in  order  to  be  heard. 
Huntington  and  Clough  were  both  very  cool,  although  I  believe  they  thought  the 
chances  were  more  than  even  that  we  should  have  quarters  elsewhere  before  morning. 
We  watched  all  night,  waiting  anxiously  the  effect  or  result  of  the  hurricane ;  and, 
after  a  long  night  of  such  fearful  tumult,  morning  brought  us  a  little  relief,  by  reducing 
the  velocity  of  the  wind  to  84  miles  per  hour.  We  were  duly  thankful  for  this  slight 
change,  and  at  breakfast  we  congratulated  each  other  on  our  narrow  escape  ;  for,  if  the 
building  had  been  crushed,  our  chance  for  wishing  any  one  a  "  Merry  Christmas"  and 
"  Happy  New  Year"  would  have  been  very  small ;  for  the  mercury  was  15°  below  zero, 
and  the  barometer,  the  lowest  recorded  so  far,  22.796.  This  remarkable  fall  will  not 
happen  often,  but  when  it  does  we  shall  keep  housed.  The  immediate  danger  is 
passed,  however,  and  our  good  cover  has  been  severely  tested,  and  has  not  been 
found  wanting  in  point  of  strength.  We  have  more  confidence  in  it  than  we  had 
before  the  storm. 

We  continue  this  narrative  with  extracts  from  the  journal,  written  by 
S.  A.  Nelson : 

December  21.  Forefathers'  Day  was  celebrated  by  the  arrival  of  Prof.  Hitchcock, 
L.  B.  Newell,  E.  Thompson,  F.  Woodbridge,  and  the  writer.  We  ascended  in  a  rough 
south-west  snow  storm,  with  the  velocity  of  the  wind  at  59  miles  per  hour.  It  is  pleas 
ant  to  be  located  at  last,  and  settled  down  for  the  coming  six  months.  It  is  quite  a 
change,  in  one  short  week  from  busy  Boston,  to  this  out-of-the-world-up-in-the-clouds 
observatory.  .  .  .  There  are  no  signs  of  animal  life  outside.  Mice  are  plenty  in  the 
house,  and  it  is  thought  that  a  sable  has  taken  up  winter  quarters  under  the  building. 

December  23.  Kimball  was  up  first  this  morning,  and  had  the  first  sight  of  as  beau 
tiful  a  sunrise  as  one  could  wish.  It  was  a  cold  morning,  the  thermometer  indicating  o  ; 
but  we  don't  feel  the  cold  as  sensibly  as  in  the  lower  regions.  Clough  and  Kimball 
took  some  fine  views  to-day, — among  them,  one  of  the  observatory,  with  Clough,  Smith, 
and  Nelson  standing  by  the  door.  Later  in  the  day,  they  took  one  from  the  roof  of 
the  hotel.  They  have  been  successful  against  odds,  having  had  but  three  days  so  far 
suitable  for  work  during  a  month's  residence. 

December  24.  Yesterday  afternoon,  and  late  at  night,  a  "snow-bank"  lay  along  the 
south  ;  this  forenoon,  snow  was  falling,  with  a  temperature  of  — 13°.  At  times,  during 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.          109 

the  day,  the  wind  was  as  high  as  seventy  miles  an  hour :  consequently  we  were  con 
fined  to  the  house.  Mr.  Smith  has  much  to  do,  many  messages  being  sent  to  and  from 
the  "lower  regions."  He  sends  his  first  regular  report  to  Washington  to-night.  We 
have  sent  a  press  despatch  of  "A  merry  Christmas  to  all  the  world  below." 

December  it).  There  were  no  clouds  above  or  around  the  summit.  Below,  and  but 
a  little  lower  than  this  peak,  the  clouds  were  dense,  and  covered  an  extensive  tract  of 
country.  Through  the  less  dense  portion  of  the  lighter  clouds,  the  sun's  rays  gave  a 
peculiar  rose  tint,  extremely  beautiful  in  effect.  This  was  my  first  cloud  view,  and  it 
was  a  treat  beyond  expectation.  .  .  .  Mr.  Smith  takes  our  four-footed  friends,  the 
sable  and  mice,  under  his  especial  care,  and  sees  that  they  get  all  the  waste  food. 
They  are  our  companions,  though  we  see  them  but  seldom. 

January  10.  The  snow  is  nearly  all  off  the  houses  and  the  rocks — a  great  change  in 
three  days'  time.  At  i  P.M.  it  was  37°.  Like  April  it  seemed  ; — but  who  knows  what 
it  will  be  to-morrow? 

January  16.  Still  raining.  At  n  this  forenoon,  Mr.  Smith  started  out  on  a  voyage 
of  discovery ;  but  it  rained  so  hard,  and  the  walking  was  so  difficult,  that  he  soon  came 
back.  Did  n't  stop  long,  however ;  he  is  too  energetic  a  man  to  give  up  easily.  So, 
putting  on  an  overcoat,  and  otherwise  prepared,  he  once  more  went  out,  determined  to 
find  the  break  in  the  wire,  if  he  had  to  go  to  Littleton.  Wished  him  good  luck,  not 
expecting  to  see  him  again  for  three  or  four  days, — and  he  was  off.  But  we  soon  heard 
the  click,  click,  click  of  the  instrument,  and  knew  that  he  had  found  the  break.  In 
half  an  hour  he  returned:  the  break  was  at  the  Gulf  tank.  Mr.  Huntington 
went  down  to  the  spring  to-day,  and  brought  up  a  pail  of  water.  A  week  ago 
this  was  an  Arctic  region ;  now  it  is  more  like  April  in  the  valleys  of  New  Hamp 
shire. 

January  17.  Perfectly  clear  at  sunset.  Had  one  of  the  best  views  of  the  shadow 
of  Mt.  Washington  yet  obtained.  The  mountains,  far  and  near,  look  gray  now  since 
the  rains. 

January  18.  I  have  seen  to-day  a  sea  of  clouds.  At  10  A.  M.,  westward  from  a  line 
due  north  and  south,  as  far  the  eye  could  see,  the  clouds  presented  the  appearance  of 
a  frozen  ocean, — the  surface  level  and  motionless,  apparently,  but  really  moving  east 
ward,  and  only  a  little  below  the  summit.  In  no  direction  west  of  a  line  north  and 
south  was  there  a  glimpse  of  mountain  or  valley.  Turning  to  the  east  the  contrast  was 
striking,  for  in  this  direction  there  was  scarcely  a  single  cloud,  and  the  atmosphere 
was  remarkably  clear.  Saco  valley  was  never  more  distinct, — while  the  range,  com 
prising  Clay,  Jefferson,  and  Adams,  was  completely  hidden ;  but  the  Carter  range 
loomed  up  as  on  a  clear  morning  when  not  a  single  cloud  can  be  seen,  and  far  away 
the  ocean  was  plainly  visible. 

January  22.  Having  a  gale  to-day,  and  not  only  a  high  wind,  but  a  temperature 
below  anything  I  have  ever  experienced  before,  now  at  9  P.  M., — 34°  inside  the  door. 
The  wind  is  80  miles,  blowing  steadily.  At  2  p.  M.,  wind  72,  Mr.  Huntington  meas 
ured  the  velocity.  He  had  to  sit  with  a  line  around  him,  myself  at  the  other  end, 


I  10  PHYSICAL    GEOGRAPHY. 

in-doors,  as  an  anchor :  even  then  it  was  almost  impossible  for  him  to  keep  his  position. 
Temperature,  — 31°. 

January  23.  The  wind  raged  all  night.  The  house  rocked  fearfully ;  but  as  we 
had  no  fear  of  a  wreck,  it  did  not  disturb  us  much.  Sometimes  it  would  seem  as  if 
things  were  going  by  the  board,  but  an  inspection  showed  everything  all  right.  It  is 
a  sublime  affair,  such  a  gale, — only  we  do  not  care  to  have  it  repeated  too  often. 
Nobody  was  hurt  or  scared,  though  there  was  not  much  sleep  for  our  party,  with  such 
an  uproar  of  the  elements.  Evidently  the  spirits  of  the  mountain  are  angry  at  this 
invasion  of  their  domain.  Toward  morning  the  wind  ceased,  and  all  day  it  has  been 
nearly  calm.  The  temperature  outside,  — 43°.  Mr.  Huntington  and  myself  sat  up 
all  night  to  keep  fires  going. 

January  31.  The  most  glorious  sunrise  this  winter.  To  the  east  was  a  sea  of 
clouds,  somewhat  broken,  and  much  lower  than  usual.  The  protruding  peaks  resem 
bled  islands  more  than  ever  before.  Over  northern  New  Hampshire  and  Maine,  and 
along  the  coast,  the  clouds  were  very  dense,  but  their  upper  surface,  as  the  sun  shone 
across  them,  was  of  dazzling  brightness,  while  singular  forms  of  cirrus  clouds  overcast 
the  sky.  Low  in  the  west  it  was  intensely  black,  and  detached  masses  of  clouds 
floated  along  the  northern  horizon.  For  an  hour  after  sunrise  all  these  cloud  forms 
were  constantly  changing  in  color, — purple  and  crimson,  leaden  hues  and  rose  tints, 
almost  black  and  dazzling  white. 

February  2,  10  p.  M.  All  day  the  wind  has  been  light,  and  it  was  nearly  calm  this 
evening  till  half  an  hour  since,  when,  without  any  warning,  the  gale  began,  not  with 
a  rising  wind,  but  a  sudden  blast  that  shook  the  house  to  its  foundations.  I  said  that 
we  had  no  warning  of  its  approach  :  we  had  notice  of  it  in  the  falling  of  the  barometer. 
A  moment  before  the  first  blast,  some  one  called  attention  to  the  quiet  night,  remarking 
that  the  storm  would  not  probably  reach  us  before  morning,  when  the  conversation 
was  suddenly  interrupted  by  the  uproar  of  the  elements. 

February  3.  We  get  to-day  the  most  severe  snow  storm  of  the  winter  so  far.  The  wind 
is  north-west,  the  point  from  which  our  storms  and  hurricanes  come.  At  no  time  has 
the  temperature  been  higher  than  5° ;  it  was  — 25°  this  morning  at  7  o'clock.  Smith 
and  myself  are  yet  on  the  sick  list,  so  all  the  hard  work  falls  to  Mr.  Huntington.  To 
add  to  the  discomfort  of  our  situation,  the  line  failed  last  night,  just  after  Smith  got  off 
the  press  despatch.  Cold  as  it  is,  and  has  been  all  day,  Mr.  Huntington  made  six  trips 
down  the  railway  repairing  line.  His  method  was  to  find  and  repair  a  break,  then  run 
for  the  house,  get  thoroughly  warmed  and  rested,  and  then  out  for  another  attempt. 
The  last  time  he  went  to  the  Gulf:  below  there  he  did  not  dare  go.  So,  as  there  is  at 
least  one  more  splice  to  make,  far  as  any  good  for  to-night  telegraphing  goes,  his 
labors  were  of  no  avail. 

February  4 — 9  p.  M.  The  wind,  rising  toward  morning,  has  held  its  own  all  day, — at 
no  time  being  below  seventy-five,  and,  since  8  : 30,  acts  as  though  it  were  ambitious  to 
attain  the  ninety-mile  standard.  This  has  been  so  cold  a  day  that  we  found  Dr.  Kane's 
voyages  most  suitable  reading.  At  7  A.M.,  —33°,  and  it  has  gradually  worked  down  to 


EXPLORATIONS  AMONG  THE  WHITE  MOUNTAINS.          Ill 

— 40°.  We  have  the  stoves  at  a  red  heat.  Ten  feet  from  the  stove,  at  the  floor  to-day, 
the  temperature  was  only  12°,  and  at  the  same  time  was  65°  in  other  parts  of  the 
room.  .  .  .  Find  that  I  froze  my  fingers  while  sawing  off  a  piece  of  pork  for  our 
"  Sunday  baked-beans  ; "  was  out  only  five  minutes.  It  was  like  cutting  into  a  block  of 
gypsum,  to  saw  off  that  piece  of  pork. 

Midnight.  Really,  there  is  quite  a  breeze  just  now.  Some  of  the  gusts,  from  what 
we  know  of  the  measured  force,  must  be  fully  up  to  one  hundred  miles  per  hour.  In 
fact,  it  is  a  first-class  hurricane.  The  wind  is  north-west,  and,  as  the  house  is  fully 
broadside  to  it,  the  full  force  is  felt.  At  times,  it  seems  as  though  everything  was  going 
to  wreck.  We  go  to  the  door  and  look  out :  it  is  the  most  we  can  do.  To  step 
beyond,  with  nothing  for  a  holdfast,  one  would  take  passage  on  the  wings  of  the  wind 
in  the  direction  of  Tuckerman's  ravine.  We  shout  across  the  room  to  be  heard.  Now 
the  wind  suddenly  lulls,  and,  moaning  and  sighing,  it  dies  away.  Then,  quickly  gath 
ering  strength,  it  blows  as  if  it  would  hurl  the  house  from  the  summit.  The  timbers 
creak  and  groan,  and  the  windows  rattle.  The  walls  bend  inward,  and,  as  the  wind 
lets  go  its  hold,  rebound  with  a  jerk  that  starts  the  joints  again.  The  noise  is  like 
rifle-firing  in  fifty  different  directions  at  the  same  moment  in  the  room — a  moment 
ago,  close  by  me  as  I  sat  here  leaning  against  the  wall,  now  in  the  outer  room,  or  up 
aloft,  and  outside  as  well.  Then  there  is  the  trembling  and  groaning  of  the  whole 
building,  which  is  constant.  Everything  movable  is  on  the  move.  Books  drop  from 
the  shelves.  We  pick  them  up  and  replace  them,  only  to  do  it  again  and  again.  We 
have  just  looked  at  the  thermometer  ;  find  the  temperature  lower  than  at  last  observa 
tion, — now  minus  40°.  Huntington  and  Smith  are  taking  hourly  observations.  When 
we  hear  an  unusually  loud  report  in  the  outer  room,  one  goes  to  inspect.  Nothing  has 
given  away  yet. 

February  5.  From  I  to  2  A.  M.,  the  wind  was  higher  than  during  the  early  part  of  the 
night.  Some  of  the  gusts  must  have  been  above  100 — possibly  no.  The  tempest 
roared  and  thundered.  It  had  precisely  the  sound  of  the  ocean  waves  breaking  on  a 
rocky  shore.  And  the  building,  too,  had  the  motion  of  a  ship  scudding  before  a  gale. 
At  3  A.M.  the  temperature  had  fallen  to — 59°,*  and  the  barometer  stood  at  22.810; 
attached  barometer,  62°.  Barometer  was  lowest  yesterday  at  8  A.M.,  when  it  was 
22.508,  and  attached  thermometer,  32°. 

9  A.  M.  Talked  over  the  events  of  the  past  night  at  the  breakfast  table,  recalling 
many  laughable  incidents,  and  agreeing  that  we  rather  enjoyed  the  night's  experience 
than  otherwise ;  that  it  was  a  sublime  affair  (having  full  confidence  that  the  house 
would  stand,  the  storm  had  no  terror  for  us)  ;  but  all  things  considered,  were  unani 
mous  in  the  opinion  that  once  in  a  fortnight  was  quite  often  enough  for  such  grand 
displays  of  the  storm-king's  power.  Of  all  the  nights  since  this  party  came  here,  the 
last  exceeds  every  one. 


*  The  Signal  Service  did  not  provide  us  with  a  spirit  thermometer;  consequently  it  is  impossible  to  say  how 
cold  it  was  at  this  time,  the  instrument  in  use  not  being  reliable  below  — 38°.     C.  H.  H. 


H2  PHYSICAL    GEOGRAPHY. 

February  6.  They  have  put  the  line  in  order  to-day,  and  Mr.  Huntington  sent  an 
interesting  press  despatch.  Wonder  if  our  situation  excites  any  comment,  especially 
as  we  have  held  no  communication  with  the  lower  world  for  three  days. 

Tuesday,  February  7.  A  glorious  sunrise,  and  a  quiet,  warm  day.  Temperature  at 
2  P.M.,  62°  in  the  sun.  Change  of  temperature  since  Sunday  of  121°!  ....  I 
have  given  some  time  this  afternoon  to  the  study  of  cloud  formations.  Days  like  this 
are  so  rare  that  we  improve  every  opportunity  for  investigation.  Gales,  storms,  hurri 
canes,  all  clear  off  with  a  north  wind, — a  wind  gentle  and  soft  as  the  south  wind  of  the 
lower  regions.  How  can  this  be  explained?  It  is  S.  S.  W.  to-night,  and  two  miles  per 
hour, — a  marked  contrast  to  Sunday  morning.  Mr.  Holden  telegraphs  from  Littleton 
that  we  may  expect  him  to-morrow. 

February  8.  Smith  and  I  laid  in  a  supply  of  ice,  enough  for  three  days'  consumption. 
Are  obliged  to  look  sharp  in  fair  weather  and  lay  in  an  ample  stock  of  ice,  for  it  some 
times  happens  that  we  cannot  replenish  for  several  days.  ...  At  noon  the  party 
arrived,  consisting  of  Messrs.  Holden,  Cogswell,  and  Clough.  They  received  from  us 
a  right  hearty  welcome.  They  brought  a  large  mail,  and  a  contribution  of  magazines 
and  papers.  Some  of  the  dailies  are  more  than  a  fortnight  old,  yet  we  read  them  with 
as  much  eagerness  as  we  do  the  evening  paper  at  home.  The  evening  has  passed 
pleasantly.  We  had  something  to  tell  our  friends  of  mountain  life  ;  and  they,  in  return, 
had  much  to  relate  of  events  occurring  since  we  left  the  region  below  the  clouds. 

February  9,  9  P.  M.  Cloudy  all  day,  wind  moderate  ;  temperature  high  as  26°.  The 
cloud  on  the  mountain  so  dense  that  it  was  impossible  to  see  ten  rods  in  any  direction. 
It  is  a  pleasure  to  have  company  in  this  out-of-the-world  place  ;  and  I  sincerely  hope 
that  we  may  be  able  to  treat  our  friends  to  some  one  or  more  of  the  Mt.  Washington 
novelties, — a  gorgeous  sunrise  or  brilliant  sunset,  a  superior  show  of  frost-work,  or, 
failing  in  these,  something  in  the  line  of  hurricanes.  It  is  a  pity  that  they  should  be 
at  the  trouble  of  making  the  ascent  at  this  inclement  season,  and  not  take  back  some 
thing  of  the  experience  that  falls  to  our  lot  daily — something  to  endure,  or  enjoy,  as  the 
case  may  be.  The  line  has  been  down  to-day  between  Littleton  and  Concord :  this 
time  it  is  not  the  Mt.  Washington  cable.  The  papers  say  that  fears  were  entertained 
for  our  safety  during  the  time  the  line  was  down.  Knowing  better  than  the  good 
people  below  all  about  the  matter,  we  had  not  the  least  anxiety. 

February  10.  The  wind  high  all  day,  88  at  2  p.  M., — Holden  having  the  honor  of 
measuring  its  velocity,  Huntington  timing  him.  He  acknowledges  perfect  satisfaction 
as  regards  Mt.  Washington  winter  winds.  Now,  7  p.  M.,  the  wind  is  rapidly  rising. 
Been  cloudy  all  day ;  a  dense  cloud  on  the  mountain,  charged  with  frost. 

Midnight.  About  8  o'clock  the- wind  had  worked  up  to  the  90  mile  rate,  and  then 
commenced  a  furious  bombardment  of  ice  from  the  summit  and  frost-work  from  off 
the  house.  The  house  shook  and  trembled  as  the  fiercer  blasts  beat  against  it.  Pieces 
of  ice  were  driven  between  the  bars  protecting  the  windows,  and  at  last,  by  one  heavy 
discharge,  three  panes  were  broken.  As  good  luck  would  have  it,  the  broken  lights 
were  in  the  room  above.  The  roar  of  the  wind  as  it  rushed  through  the  opening  was

enough  to  wake  a  Rip  Van  Winkle.  Huntington,  Clough,  Smith,  and  myself,  were 
out  in  a  moment,  and  after  having  the  "hurricane"  lantern  twice  extinguished  (it  is 
warranted  to  burn  the  brighter  the  higher  the  wind),  we  succeeded  in  nailing  boards 
over  the  aperture.  Still  the  bombardment  was  going  on  for  an  hour,  but  no  more  glass 
was  broken.  The  supply  of  ammunition  was  exhausted  by  10  o'clock,  and  then,  though 

the  wind  was  terrific,  we  did  not  mind  the  gale The  line  failed  just  after 

Holden's  Journal  despatch  went.  One  thing  more :  our  friends  have  had  the  enjoy 
ment  of  a  very  respectable  if  not  a  first-class  gale.  It  does  not  seem  now  as  if  it  would 
rise  to  the  rank  of  that  of  December,  January,  or  the  one  of  last  week.  The  temper 
ature  at  9  P.  M.  was  — 20°.  Hourly  observations  to-day. 

February  13.  The  party  left  at  11:20.  Smith  and  I  watched  them  going  down  as 
long  as  we  could  see  them,  and  then  returned  to  the  house,  perhaps  a  little  envious: 
more  silent  we  certainly  were  than  usual,  though  this  is  not  the  first  time  we  have  lived 
by  ourselves.  Really,  these  few  days  have  passed  most  agreeably.  .  .  .  The  clouds 
in  the  morning  did  not  present  any  remarkable  features  for  this  locality,  but  from  3  to 
4  130  P.  M.  there  was  an  extensive  "sea  of  clouds."  It  extended  from  a  point  60  miles 
north,  far  as  the  ocean  east,  bounded  only  by  the  horizon.  This  summit  was  alone 
above  the  cloud.  It  was  to  the  eye  a  frozen  polar  ocean,  here  and  there  a  lofty  moun 
tain  of  ice  rising  from  the  apparent  dead  level  surface.  The  setting  sun,  throwing  a 
silvery  light  along  the  cloud,  dispelled  the  illusion.  Perfectly  clear  overhead  all  day ; 
our  sunny  day  contrasts  strongly  with  the  cold,  gloomy,  cloudy  one  below.  If  we  have 
much  cloud  here,  it  is  not  always  sunshine  there. 

February  22.  The  only  perfectly  clear  day  this  month;  cool,  the  mean  temperature 
being  but  2°.  These  clear  days,  and,  if  nearly  calm,  so  much  the  better,  are  the  chief 
attractions,  or  rather  -among  them,  for  cloud-views  count  in  the  list.  On  such  days 
even  the  most  distant  mountain  peaks  are  clearly  outlined.  Katahdin  is  to-day  plainly 
seen,  as  are  some  mountains  in  Canada  as  distant.  The  view  is  not  often  good  in  a 
southerly  direction ;  it  is  not  to-day.  The  mountains  belonging  to  this  group  show 
grandly  in  the  bright  sunlight.  .  .  .  Smith  has  been  working  on  the  line,  and  I 
have  spent  the  day  in  writing.  In  such  weather  this  is  a  pleasant  winter  residence. 

Anniversary  of  Washington's  birthday,  and  we  had  not  thought  of  it  until  now!  We 
might  have  raised  our  little  flag  in  honor  of  the  day, — it  would  have  been  "quite  the  thing." 

February  26.  A  morning  perfect  as  a  morning  of  winter  can  well  be.  Clouds  in  the 
valleys, — the  ocean  visible  for  a  long  distance  up  and  down  the  coast,  and  far  out  at 
sea.  About  9  A.  M.  a  heavy  cloud  commenced  to  move  inland,  one  portion  of  it  mov 
ing  up  the  Saco  valley.  Its  progress  was  so  slow  that  it  did  not  shut  the  Glen  house  in 
till  7  P.  M. 

February  28.  This  is  one  of  those  days  which  make  us  contented  with  our  home.  It 
cleared  off  early  in  the  morning.  Wind  from  50  to  70  miles  per  hour.  The  mean 
temperature  for  to-day  is  o°.  The  frost-work  is  again  fine ;  and  the  house,  if  not  a 
marble  palace,  looks  like  a  building  fashioned  from  purest  marble, — no  part  of  the 
chains,  wooden  braces,  or  finish  to  be  seen.

I  14  PHYSICAL    GEOGRAPHY. 

March  11.  The  morning  was  so  fine  that  we  felt  invited  out.  The  snow  is  nearly  all 
gone.  The  rocks  look  charming  in  their  Alpine  dress  of  beautiful,  pale  green  moss 
lichen.  We  were  so  fortunate  as  to  discover  a  fine  bunch  of  Greenland  sandwort — one 
in  bloom.  I  took  up  some  of  each  for  house-plants,  that  our  parlor  may  boast  its 
winter  garden. 

March  23.  This  morning  there  was  a  thick  stratum  of  clouds  eastward,  at  a  moderate 
elevation  above  the  summit.  By  8  A.  M.  it  was  quite  dense  ;  at  9  A.  M.,  snow-squalls  to 
the  north-east,  and  the  clouds  gradually  settling  in  the  valleys ;  1 1  o'clock,  thick  on 
the  Carter  range;  by  12,  clouds  all  about,  except  on  the  summit.  By  2  P.M.  the 
mountain  was  in  clouds.  The  formation, — for  I  can  call  it  nothing  else, — and  progress 
of  the  storm  were  very  interesting.  The  clouds  were  at  a  higher  elevation  than  has 
generally  been  the  case, — cirro-stratus,  color  gray,  uniform  in  density  over  nearly  the 
entire  field  of  view ;  thick  along  the  south-east,  east,  and  north-east,  long  before  it 
shut  down  elsewhere.  Evidently  the  lower  current  of  the  wind  was  from  the  east, 
while  the  wind  on  the  summit  was  west-north-west.  It  was  two  hours  from  the  time 
the  Carter  range  shut  in  before  the  summit  was  enveloped.  The  clouds  poured  over 
Mt.  Adams,  and,  later,  over  the  dividing  ridge  between  Mts.  Washington  and  Clay. 
They  seemed  to  curve,  as  they  passed  over  these  mountain-tops,  as  though  the  upper 
currents  of  air  conformed  to  the  irregularities  of. surface.  When  there  are  two  strata 
of  clouds,  they  unite  before  the  snow  or  rain  falls,  as  a  rule,  though  to-day  snow  fell  an 
hour  previous  to  the  clouds  settling  on  the  mountain. 

April 4.  All  the  forenoon,  till  i  P.M.,  the  summit  was  in  a  dense  cloud.  Suddenly 
it  lifted,  or  passed  off,  and  then  we  had  the  most  gorgeous  display  of  cloud-scenes  we 
have  yet  witnessed.  Eastward,  masses  of  aunuli  rested  over  the  valleys  and  the  moun 
tains.  Why  not  call  them  mountains  of  cloud?  Certainly.  They  rise  far  above  our 
level,  six  thousand,  or  perhaps  eight  thousand,  feet  higher  than  this  peak!  They  con 
form  to  the  heights  over  which  they  lie,  and  seem  to  envelop  other  mountains 
nearly  as  lofty  as  their  upper  limits.  The  illusion  was  perfect;  and  Mt.  Washington, 
in  comparison,  was  a  diminutive  spur  or  outlying  peak  of  this  great  mountain  range. 
Without  ever  having  seen  the  Alps,  I  understood  them  better  for  having  seen  these 
cloud  mountains.  The  sun  runs  high,  but  we  know  nothing  of  spring.  It  is  more  like 
winter  than  some  of  the  time  in  March.  Then  there  was  no  snow; — now  everywhere 
there  is  snow  and  ice. 

April  5.  All  day  there  has  been  a  furious  storm  of  snow, — at  one  time  wind  86,  and 
temperature  low  as  2°.  9  p.  M.,  wind  60,  and  clear.  This  afternoon  we  were  surprised 
by  the  arrival  of  Messrs.  Clough  and  Cheney.  They  were  somewhat  frost-bitten,  ears, 
fingers,  and  feet,  and  it  was  doubtful,  for  a  half  hour,  how  badly.  But  now  they  are 
all  right,  though  their  hands  and  ears  are  considerably  swollen.  It  is  the  toughest 
storm  in  which  any  party  has  made  the  ascent  this  winter. 

April  28.  At  4  P.  M.,  started  down  the  railroad,  expecting  to  meet  Mr.  Huntington 
and  Mr.  Holden.  To  show  the  changes  of  temperature  here,  in  a  few  feet  of  altitude, 
I  note  my  trip  down  to-day,  and  up  as  well.  Left  the  house  at  4:  30  p.  M.,  wind  30

miles ;  at  the  Lizzie  Bourne  monument,  40 ;  at  the  Gulf  house  ruins  and  below,  fully 
60,  thus  reversing  the  order  of  things  in  regard  to  wind.  Thermometer  on  the  sum 
mit,  28°  ;  frost-work  forming  some  distance  below  the  monument.  At  the  Gulf  tank,

The  dark  cone  is  shadow  of  observer  with  glory  about  the  head.  Above  the  foreground  is  the  shadow  of  the 
mountain,  while  the  large  circle  is  the  colored  prism  or  corona  resting  on  clouds,  and  partially  obscuring  the  two 
shadows. 

when  the  sun  came  out,  as  it  did  several  times,  the  ice  on  my  cap  would  thaw  com 
pletely  ;  then,  while  the  cloud  was  passing,  icicles  two  inches  in  length  would  form  on 
the  visor.  It  was  difficult  to  walk  or  even  stand  against  the  wind  below  the  Gulf  house 
ruins.  Returning,  the  wind  was  not  so  violent ;  rain  as  far  as  the  plateau,  where  they 
collect  water  for  the  engine  in  summer ;  mist  on  the  summit,  with  thermometer 
28°  at  6:  50. 

April  30.  We  have  had  the  past  month  more  clouds  than  sunshine,  more  snow  than 
rain ;  light  winds  and  few  gales,  the  clouds  often  dense  on  the  summit  when  clear 
below.  Now  only  on  the  higher  peaks,  in  the  deep  ravines,  and  a  few  places  on  wooded 
slopes  is  there  snow. 

May  2.  Taking  advantage  of  the  day,  Mr.  Holden  and  myself  set  out  for  Tucker- 
man's  ravine.  Found  more  snow  than  on  the  gth  ult.  Sunlight  bright  and  warm 
there,  but  over  Washington  a  dense  cloud  most  of  the  afternoon.  The  air  spring-like, 
as  were  the  surroundings ;  little  snow  except  at  the  head  of  the  ravine,  where  the  arch 
will  be  looked  for  in  vain  next  summer,  unless  May  makes  up  for  the  short-comings  of

winter.  Hermit  lake  really  breaking  up,  and  the  stream  open  above.  We  could  see 
the  pretty  cascade  some  distance  above  the  lake,  and  hear  the  rushing  waters,  now 
loudly  as  the  wind  arose,  now  softly  murmuring  as  it  fell.  Half  way  down  the  northern 
side,  under  a  sheltering  rock,  we  lunched  on  hard  tack  and  sugar,  drinking  the  pure 
water  of  a  little  rill  which  ran  down  among  the  rocks.  Then  for  an  hour  we  climbed 
the  crags,  getting  views  from  many  different  points. 

Came  away  at  3  P.  M.,  too  early  to  go  home,  so  decided  on  a  trip  to  the  north-eastern 
spur  of  Washington.  Passed  a  deep  spring  of  excellent  water,  which  in  my  jaunts  I 
had  never  seen,  then  visited  the  ravine  beyond.  In  some  respects  this  is  even  more 
interesting  than  Tuckerman's,  for  what  is  wanting  in  extent  is  made  up  in  boldness  of 
outline,  its  steep,  sloping  northern  side,  and  sheer  precipice  of  two  hundred  feet  or 
more  on  the  south.  Seven  seconds  was  the  time  taken,  by  repeated  trials,  for  a  stone 
to  reach  the  bottom.  We  propose  that  Huntingtoii's  Ravine  shall  be  its  future 
designation.  [See  frontispiece.] 

May  3.  Snowing  all  night,  and  cloudy  all  day.  Mr.  Smith  sick, — seems  no  better; 
a  rough  place  to  be  sick  in  ; — safe  from  the  doctors,  he  has  that  comfort ! 

May  4.  Another  tough  snow-storm.  ...  A  pair  of  birds  have  made  the  house 
their  home  of  late.  To-day,  especially,  they  have  hardly  been  out.  This  afternoon 
they  have  sung  several  songs  for  our  benefit.  To-night  they  sit  on  the  beam  over  this 
room,  close  by  the  flue,  and  we  can  occasionally  hear  them  twitter,  softly  calling  to 
each  other. 

On  May  6,  Messrs.  Holden  and  Nelson  visited  Mt.  Adams.  A  description  of  a 
phenomenon  seen  on  their  return  is  given  as  follows  :  "In  ascending  the  cone  of  Mt. 
Washington  we  again  got  above  the  cloud  level,  and  enjoyed  a  rare  sunset  scene.  We 
also  witnessed  a  veritable  battle  of  the  clouds.  The  wind,  which  had  been  very  light 
throughout  the  day,  had  appeared  to  come  from  different  directions  at  different  points, — 
now  from  the  east,  in  another  place  from  the  north  or  north-west,  and  again  from  the 
west  or  south-west.  We  had  ascended  a  little  distance  above  the  Gulf  tank,  when  we 
turned  and  observed  two  ghostly  armies  approaching  each  other,  one  from  the  direction 
of  Mt.  Monroe,  and  the  other  from  out  the  depths  of  the  Great  Gulf.  Noiselessly 
they  marched  onward,  and  the  conflict  came  near  the  gap  between  Mts.  Washington 
and  Clay.  The  battle  was  short  and  decisive.  Little  fragments  of  cloud,  like  wreaths 
of  smoke,  were  flung  high  in  air,  and  there  seemed  a  momentary  indecision,  but  the 
fleecy  forms  from  the  south-west  were  soon  fleeing  before  the  fast  gathering  hosts  of 
the  east,  until  all  were  commingled  in  one  shadowy  mass." 

May  j.  The  barometer  fell  5o-iooths  from  last  night  at  9  o'clock  to  this  morning  at 
7  o'clock.  Wind  rising  at  3  A.  M.,  reaching  the  highest  velocity  at  2  p.  M.,  which  was 
67, — highest  recorded  for  some  time,  forcibly  reminding  us  of  the  winter  months. 
Snowing  all  day ;  the  whirling,  driving  clouds  of  snow  made  it  far  from  pleasant  to 
stay  out  for  three  minutes,  the  time  occupied  in  taking  the  force  of  the  wind.  At 
5  P.  M.  the  cloud  passed  off,  and  we  could  see  that  not  the  mountains  alone,  but  the 
lower  country  as  well,  were  "snow  bound." 


EXPLORATIONS    AMONG    THE    WHITE    MOUNTAINS. 

May  II.  A  wintry  sky  and  winter  scenery  this  morning :  the  sky  a  pale  blue,  and  the 
sunshine  that  of  December.  The  clouds  presented  an  infinite  variety  of  shades — gray, 
brown,  and  dingy  black.  Distant  mountains  showed  clear  cut  outlines  ;  snowy  peaks 
of  the  higher  mountains  glisten  in  the  morning  light.  Looking  beyond  them  we  see  a 
change.  The  Androscoggin  is  broader,  and  its  waters  sparkle  in  the  play  of  sunlight; 
the  valleys  are  bare  and  brown.  Last  winter,  the  river  was  a  silver  thread ;  the  low 
lands  white  as  are  these  summits  now.  Only  these  differences  between  a  pleasant 
morning  last  December  and  this.  Twenty  degrees  at  7  A.  M. 

Mr.  Huntington  expects  to  leave  us  soon.  How  quickly  the  winter  has  passed,  spite 
of  storms,  hurricanes,  and  clouds, — of  discomfort,  and  rather  hard  fare,  and  the  many 
deprivations.  Smith  is  still  far  from  well.  To  endure,  without  suffering  in  some 
respect  the  sudden  changes  of  weather,  one  needs  an  iron  constitution ;  and  any  one 
that  stays  here  should  have  a  will  equally  as  strong.  It  is  hard  on  an  invalid.  I  can 
bear  testimony  to  that. 

May  12.  The  last  press  telegram  goes  to-night.  Nor  shall  we  any  longer  have  pleas 
ant  evening  chats  by  telegraph  with  Prof.  Hitchcock  at  Hanover.  Smith  is  at  the  depot 
to-night;  and  the  telegraph  has  no  word  for  us. 

May  14.  The  wind  was  high  as  80,  if  not  higher,  during  the  night.  All  day,  as 
usual,  it  has  been  cloudy,  and  frost-work  forming.  Temperature  at  /A.M.  was  11°, 
and  highest  for  the  day,  at  9  P.  M.,  21°.  At  no  time  was  the  wind  lower  than  46.  Mr. 
Huntington  left  at  9  A.  M.,  in  the  face  of  a  48-mile  gale,  and  the  temperature  only  14°. 
I  am  anxious  for  his  safety,  and  shall  be  till  Smith  returns.  To-night,  for  the  first  time, 
I  am  keeping  "watch  and  ward"  on  the  mountain-top  alone. 

The  winter's  work  is  done.  We  trust  that  it  has  not  been  time  and  labor  lost. 
Storms  of  unparalleled  severity,  when,  for  days  in  succession,  the  summit  was  enveloped 
in  clouds,  and  the  hurricanes  lasted  longer,  and  were  more  violent  than  any  yet  recorded 
in  the  United  States,  together  with  very  low  temperatures,  have  been  a  part  of  our 
experience. 

Though  interesting,  these  grand  atmospheric  disturbances  are  not  the  most  enjoyable 
features  of  mountain  life.  There  were  mornings  when  the  atmosphere  was  so  trans 
parent,  and  the  sky  so  pure  a  blue,  with  not  a  fleck  of  cloud,  the  snowy  mountain- 
peaks  so  dazzlingly  white,  their  forms  so  clearly  outlined  and  standing  up  in  such  bold 
relief,  that  they  seemed  the  creation  of  yesterday ;  and  mornings  when  earth  and  sky, 
forests,  lakes,  and  rivers,  and  the  clouds  above,  wore  a  radiance  and  richness  of  color 
never  seen  in  other  than  mountain  regions  and  from  the  loftiest  elevations.  There 
were  days  when  the  shifting  views  of  each  hour  furnished  new  wonders  and  new  beau 
ties, — in  the  play  of  sunlight  and  changing  cloud-forms, — every  hour  a  picture  in  itself, 
and  perfect  in  details.  Sunsets,  too,  when  an  ocean  of  clouds  surrounded  this  island- 
like  summit,  the  only  one  of  all  the  many  high  peaks  visible  above  the  cloud  billows, 
all  else  of  earth  hidden  from  sight.  There  were  times  when  this  aerial  sea  was  bur 
nished  silver,  smooth  and  calm ;  and  times  when  its  tossing  waves  were  tipped  with 
crimson  and  golden  fire.

PHYSICAL    GEOGRAPHY. 


Although  our  situation  has  been  very  much  an  isolated  one,  and  the  area  of  our  little 
world  limited,  our  daily  life  has  not  been  without  incident  or  void  of  interest, — to  us,  at 
least.  But  now,  our  work  being  done,  we  go  down  to  the  busy  world  once  more.  And 
though  we  look  forward  to  the  change  with  anticipations  of  pleasure,  we  half-regretfully 
turn  our  backs  upon  this  majestic  old  mountain,  whose  cloud-enveloped  summit  has  so 
long  been  our  home. 


NOTE.  It  is  proper  to  add,  in  respect  to  these  disconnected  notes  of  the  expedition,  that  this  journal  was  kept 
for  private  reference  by  Mr.  Nelson,  with  no  intention  or  expectation  of  its  being  published.  But  when  an 
extended  publication  of  the  history  of  the  expedition  was  decided  on,  it  was  found  desirable  to  use  parts  of  the 
journal  to  convey  an  idea  of  winter  life  upon  the  mountain,  and  of  the  experiences  and  impressions  of  the  party. 
A  more  connected  and  particular  description  of  the  meteorological  phenomena,  with  the  deductions  obtained 
from  their  comparison,  is  separately  presented,  exhibiting  the  practical  results  of  the  expedition.

CHAPTER    V. 


CLIMATOLOGY    OF    NEW    HAMPSHIRE. 


BY   J.    H.    HUNTINGTON. 


>HE  great  south-west  current,  that  bears  northward  the  moisture 
from  the  gulf,  and  renders  fertile  not  only  the  great  valley  of  the 
Mississippi  but  also  the  Atlantic  states,  the  physical  contour  of  the 
country  and  its  proximity  to  the  ocean,  determine  chiefly  the  climate  of 
New  Hampshire.  Yet  there  is  still  another  cause,  though  more  remote, 
that  may  have  a  greater  influence  than  we  might  at  first  suppose.  The 
great  current  from  the  Pacific,  at  first  moisture  laden,  comes  in  contact 
with  the  mountain  ranges  extending  north  and  south.  The  cold  summits 
condense  the  moisture,  and  when  the  current  reaches  the  third  great 
range  it  is  deprived  almost  altogether  of  its  moisture ;  yet  this  great  cur 
rent  affects  the  climate  eastward,  for  it  is  in  the  immediate  vicinity  of 
this  mountain  range  that  by  far  the  greater  proportion  of  the  atmos 
pheric  disturbances  are  generated,  the  influence  of  which  extends  to  the 
Atlantic  coast,  and  gives  us  the  precipitation  of  moisture  that  renders 
fertile  our  valleys,  hill-sides,  and  mountain  slopes. 

After  passing  the  third  mountain  range,  the  air,  deprived  of  its  mois 
ture,  allows  the  rays  of  the  sun  to  pass  through  it,  and  very  little  heat  is 
absorbed  until  they  come  near  the  surface  of  the  earth.  The  thin 
stratum  of  air  that  contains  moisture  becomes  heated,  and  at  intervals  it 


CLIMATOLOGY    OF    NEW    HAMPSHIRE.  121 

rises,  thus  creating  an  area  of  low  pressure,  which  is  the  nucleus  of  the 
storm  area  that  is  carried  eastward  across  the  continent.  The  other 
great  storm-centre  is  within  the  tropics.  The  great  current  of  the  south 
east  trade-wind  infringes  on  the  north-cast  trade-wind,  and  produces  the 
cyclones  that  are  so  destructive  in  the  West  Indies  and  on  the  coast  of 
Florida.  The  cyclone  thus  generated  moves  along  our  coast,  generally 
with  greatly  diminished  force,  and  thus  we  have  our  north-east  storms. 
The  character  of  these  storms  was  first  pointed  out  by  Franklin,  and 
the  theory  as  to  their  origin  has  been  discussed  by  Espy,  Redfield, 
Maury,  and  others,  while  Prof.  Joseph  Henry  was  the  first  to  explain  the 
origin  of  the  storms  that  move  eastward  across  the  continent.  In  sum 
mer,  the  disturbances  seem  to  originate  chiefly  in  the  vicinity  of  the 
Rocky  Mountains,  while  in  spring,  autumn,  and  winter,  frequently,  they 
have  their  origin  within  the  tropics. 

From  the  observations  of  the  Signal  Service,  we  find  that  there  are 
from  seven  to  thirteen  areas  of  low  barometer  developed  per  month 
within,  or  pass  along  the  border  of,  the  United  States.  Of  these,  from 
one  to  three  pass  directly  across  or  along  the  border  of  New  Hampshire. 

WEATHER  MAP. 

The  weather  map  on  the  opposite  page  shows  graphically  the  tracks 
of  the  storm-centres  for  January,  1 874.  It  will  be  seen  that  two  of  the 
storm-centres  passed  directly  across  New  Hampshire  ;  and  it  will  also  be 
seen  that  the  storms,  as  a  whole,  are  chiefly  of  the  type  that  have  their 
origin  in  the  vicinity  of  the  Rocky  Mountains.  The  dotted  line  from  the 
Pacific  coast  indicates  only  the  probability  that  the  storm-centre  passed 
over  that  section  of  the  country.  The  storms  from  the  south  usually  pass 
along  or  nearer  the  coast  than  the  one  represented  on  this  map.  By  trac 
ing  each  storm-centre,  a  person  can  get  some  idea  as  to  the  probability  of 
the  Signal  Service  being  able  to  give  accurate  forecasts  of  the  weather. 
On  account  of  our  high  latitude,  sea  border,  our  lofty  mountains  and  nar 
row  valleys,  for  our  limited  area  the  climate  is  exceedingly  varied.  On 
the  coast,  the  cold  of  winter  and  the  heat  of  summer  are  moderated  by  the 
breezes  of  the  ocean.  Inland,  for  a  very  few  days  in  summer,  we  have 
more  than  the  heat  of  the  tropics ;  while  on  our  highest  mountain  sum 
mits  in  winter,  we  have  the  climate  of  Greenland, — if  anything,  more

intense,  on  account  of  the  fierce  winds.  In  the  southern  portion  of  the 
state  we  have  the  trees  and  the  birds,  and  we  raise  the  grain  and  the 
fruits  common  in  the  Northern  states,  while  on  the  slopes  of  the  moun 
tains  and  on  the  highlands  in  the  vicinity  of  Connecticut  lake,  we 
have  the  trees  and  the  birds,  and  raise  only  the  grain  and  the  fruits  of 
the  far  north. 

Notwithstanding  our  extremes  of  temperature,  we  have  a  climate  far 
more  healthful  than  that  of  most  of  the  states  east  of  the  Rocky  Moun 
tains.  The  extreme  heat  of  summer  is  of  so  short  a  duration  that  it  does 
not  produce  the  enervating  effect  of  long  continued  heat,  though  of  a 
considerably  lower  temperature.  The  bracing  air  of  winter,  and  the 
charm  of  our  autumn  months,  largely  compensate  for  the  few  extremes 
of  summer  and  of  winter.  The  lassitude  produced  by  months  of  heat  in 
southern  latitudes,  and  the  extremes  of  cold,  accompanied  by  fierce  winds 
that  descend  with  such  fell  swoop  in  the  west,  are  both  unknown;  for 
with  us  winds  of  great  velocity,  accompanied  by  intense  cold,  except  on 
the  summits  of  our  mountains,  are  extremely  rare. 

MOISTURE  OF  THE  ATMOSPHERE. 

The  climate  of  a  country,  as  affecting  vegetation,  does  not  depend 
altogether  upon  the  absolute  amount  of  rain-fall  during  the  year ;  but  in 
New  Hampshire,  particularly,  the  rain  must,  be  distributed  through  the 
months  when  vegetation  is  growing,  so  that  drouth  will  not  check  its 
growth.  Even  when  vegetation  is  growing,  there  must  be  other  condi 
tions  of  moisture  than  rain-fall.  The  most  important  is  the  relative 
humidity  of  the  atmosphere.  This  is  the  relative  amount  of  moisture  in 
the  atmosphere,  compared  with  that  which  it  is  capable  of  sustaining  at 
a  given  temperature.  Saturation  is  assumed  as  100,  and  perfectly  dry  air 
as  o.  The  following  is  the  absolute  amount  of  moisture  at  the  given 
temperatures.

Suppose  the  temperature  is  30°,  and  the  absolute  amount  of  moisture 
in  the  atmosphere  is  2  grains,  then  there  is  half  the  amount  present  that 


CLIMATOLOGY    OF    NEW    HAMPSHIRE.  123 

the  atmosphere  can  sustain:  hence  the  relative  humidity  is  50  per  cent 
Now,  if  the  temperature  rises  just  above  70°,  and  the  amount  of  moisture 
is  not  increased,  there  is  only  one  fourth  the  amount  of  moisture  that  the 
atmosphere  can  sustain  at  that  temperature ;  hence  the  relative  humidity 
is  25  per  cent.  If,  on  the  other  hand,  the  temperature  falls  to  30°,  there 
is  more  moisture  than  the  atmosphere  can  sustain,  and  it  is  precipitated. 
The  air  feels  moist  or  dry,  not  from  the  absolute  amount  of  moisture 
present,  but  from  its  relative  humidity.  If  the  per-centage  is  small,  the 
moisture  evaporates  rapidly  from  the  earth  and  from  vegetation,  as  well 
as  from  everything  containing  moisture.  The  opposite  effect  is  seen  on 
the  approach  of  rain.  After  a  drouth,  water  is  seen  where  there  had  been 
none  for  weeks ;  and  the  partially  withered  leaves  assume  their  natural 
shape, — so  much  so  that  we  should  scarcely  know  that  they  had  been 
affected  by  a  drouth  :  and  all  this  before  a  drop  of  rain  has  fallen.  Why  ? 
Because  the  air  is  approaching  saturation,  and  moisture  is  no  longer 
evaporated  from  the  earth  and  vegetation. 

The  vapor  of  water  diffused  through  the  air  is  an  obstruction  to  the 
free  passage  of  the  heat  of  the  sun,  and  also  prevents  the  sudden  radia 
tion  of  the  heat  that  has  been  absorbed  by  the  earth.  "This,"  says 
Buchan,  "is  undoubtedly  one  of  the  most  important  and  conservative 
functions  of  the  invisible  moisture  of  the  atmosphere.  For  if  the  mois 
ture  was  drained  out  of  it,  and  its  diathermacy  thereby  rendered 
complete,  the  sun's  rays  would  burn  up  everything  by  their  intolerable 
fierceness ; "  and  during  the  night  the  escape  of  heat  by  radiation  would 
be  so  rapid  that,  ere  the  sun  appeared  again,  everything  would  perish  that 
a  freezing  temperature  could  kill.  We  see  the  effect  of  the  want  of 
moisture  frequently  in  New  Hampshire,  in  the  extremely  hot  days  and 
cold  nights  that  invariably  accompany  a  long  drouth. 

EFFECT  OF  FORESTS. 

How  far  the  removal  or  renewal  of  forests  affects  our  climate,  is  some 
thing  in  which  every  one  is  interested.  From  the  data  that  we  have, 
it  may  be  impossible  to  generalize  to  any  great  extent ;  yet  there  are  some 
things  that  we  can  learn  from  the  observations  that  have  been  made. 
While  it  is  stoutly  contended  that  there  has  been  no  decrease  in  the 
annual  amount  of  rain-fall  in  the  eastern  part  of  the  United  States,  there 


124  PHYSICAL    GEOGRAPHY. 

arc  facts  that  show  that  forests  have  a  great  influence  on  the  climate, — if 
not  on  the  annual  rain-fall,  yet  on  its  distribution  during  the  months  of 
the  year  and  the  hours  of  the  day. 

In  the  central  and  southern  portion  of  New  Hampshire,  the  hay  crop 
is  frequently  cut  short  by  drouth,  while  in  the  northern  portion  of  the 
state,  often  the  same  year,  the  hay  crop  is  above  the  average ;  yet  the 
annual  rain-fall  is  less  in  the  northern  than  either  in  the  central  or 
southern  part  of  the  state.  But  in  the  north  there  are  abundant  forests ; 
and  the  rain  is  distributed  through  the  months  when  it  is  needed  for  the 
crops  to  grow  and  mature.  The  effect  of  the  diminution  and  increase  of 
vegetation  is  shown  in  the  well  known  facts  in  regard  to  Lake  Tacarigua, 
Venezuela.  During  the  last  thirty  years  of  the  past  century,  it  was  found 
to  be  gradually  drying  up;  but  when  the  valley  of  Aragua  was  devastated 
by  war,  the  country,  by  the  rapid  growth  of  vegetation,  was  soon  covered 
with  forests ;  and  it  was  observed  by  Boussingault  that  the  water  of  the 
lake  had  risen  so  that  it  covered  much  of  the  country  that  was  formerly 
cultivated. 

The  gradual  rise  in  the  height  of  the  water  of  the  Great  Salt  lake,  in 
Utah,  at  the  rate  nearly  of  a  foot  per  year,  and  the  gradual  increase  in 
rain-fall  more  than  three  inches  per  year  since  the  country  has  been  cul 
tivated, — and  there  has  been  a  great  increase  of  vegetation  on  account  of 
irrigation, — is  an  important  example,  as  showing  the  effect  of  the  increase 
of  vegetation.* 

The  preservation  of  the  vegetation  on  our  mountains  is  of  great 
importance,  not  only  in  modifying  the  distribution  of  rain,  but  also  in 
moderating  the  extremes  of  cold  in  winter. 

Our  mountains,  especially  the  higher  summits,  except  where  it  has  been 
destroyed  by  fire,  are  covered  to  a  considerable  depth  by  peat  formed 
chiefly  from  moss  and  lichens.  Now  it  has  been  found  by  experiment 
"that  peat  moss  can  absorb  more  than  twice  its  own  weight  of  water,  dry 
clay  nearly  its  own  weight,  dry  earth,  or  garden  mould,  more  than  half  its 
own  weight,  and  dry  sand  a  little  more  than  a  third  of  its  own  weight. 
With  equal  times  of  drying,  under  the  same  circumstances,  peat  moss  lost 
two  thirds  of  all  the  water -it  contained,  clay  and  earth  more  than  three

fourths,  and  sand  more  than  nine  tenths."  Farmers  can  determine  the 
capacity  that  different  soils  have  for  retaining  moisture,  by  taking  two 
boxes,  filling  each  with  a  different  kind  of  soil,  and  pouring  an  equal 
quantity  of  water  on  each,  and  then  suspending  each  of  the  boxes  at  the 
end  of  a  balance,  so  adjusted  that  the  bar  shall  be  horizontal.  Then,  if 
the  soils  are  unequal  in  their  capacity  for  retaining  moisture,  one  box  will 
soon  rise  above  the  level  of  the  other.  This  experiment  was  first  per 
formed  by  D.  Milne  Home.  When  a  mountain  has  been  denuded  of  its 
forests  and  vegetable  mould,  the  rain  that  falls  upon  it  flows  immediately 
into  the  streams,  and  is  carried  to  the  ocean ;  then,  before  another  rain, 
the  streams  are  dried  up,  the  rivers  are  greatly  contracted,  and  the  next 
rain  causes  a  freshet; — so  we  have  a  succession  of  drouths  and  floods. 
On  the  other  hand,  vegetable  mould  retains  the  moisture,  and  it  is  grad 
ually  evaporated,  a  high  relative  humidity  is  maintained,  springs  gush 
forth  from  the  slopes  of  the  mountains,  the  streams  are  full,  but  not  to 
overflowing,  and  a  slight  change  in  the  temperature  causes  rain  to  fall  in 
gentle  showers. 

There  is  one  marked  feature  in  regard  to  the  mountains  in  New  Hamp 
shire  that  have  been  burned,  namely,  the  fact  that  the  fire  has,  in 
general,  spread  only  over  their  eastern  slopes,  and  when  it  has  reached 
the  summits  it  has  extended  but  a  short  distance  down  the  western 
slopes,  showing  that  the  moisture-bearing  currents  of  wind  come  from 
the  west  or  south-west.  Although  it  is  of  great  importance  that  the 
mountains  should  be  covered  with  vegetation,  yet  it  is  of  no  less  impor 
tance  that  there  should  be  a  certain  amount  of  forest  over  the  entire 
country,  and  this  amount  should  be  at  least  thirty  per  cent,  of  the  whole 
area.  In  some  parts  of  the  state  the  area  covered  by  forests  is  much  less. 
The  general  effect  of  forests  on  temperature  is  to  make  the  nights 
warmer  and  the  days  cooler,  and  to  moderate  the  extreme  heat  of  sum 
mer,  making  it  less  intense,  and  the  cold  of  winter  less  severe.  In  New 
Hampshire,  during  the  winter,  in  calm,  clear  weather,  the  cold  is  more 
intense,  or,  at  least,  the  thermometer  goes  lower  in  the  valleys  than  on 
moderate  elevations,  or  even  on  the  summit  of  Mt.  Washington.  As  the 
stratum  of  air  in  contact  with  the  earth  often  becomes  colder  by  contact, 
and  as  the  cold  air  is  heavier  than  the  warmer  currents,  the  cold  air  flows 
down  the  valleys  like  currents  of  water.  Hence  in  the  Connecticut  and 


126  PHYSICAL    GEOGRAPHY. 

Merrimack  valleys,  where  these  currents  converge  and  become  united, 
the  cold  is  the  most  intense.  Where  the  mountain  slopes  and  valleys  are 
wooded,  the  flow  of  these  cold  currents  is  greatly  impeded.  In  windy 
and  stormy  weather  there  is,  however,  a  gradual  decrease  of  temperature 
according  to  the  height.  This  decrease,  comparing  the  observations  at 
Hanover  with  those  on  the  summit  of  Mt.  Washington,  is  one  degree 
for  every  three  hundred  and  fifty-four  feet ;  but  observations  continued 
for  a  series  of  years  might  greatly  modify  this  ;  or,  if  we  make  the  com 
parison  at  different  seasons  of  the  year,  we  find  that  the  decrease,  taking 
the  monthly  mean,  is  one  degree  for  every  five  hundred  feet  in  January, 
while  it  is  the  same  in  May  for  only  two  hundred  and  eighty-four  feet. 

CHARTS  AND  DIAGRAMS. 

In  order  to  present  clearly  the  leading  features  of  the  climate  of  New 
Hampshire,  we  have  prepared  several  charts  and  diagrams.  These  are 
chiefly  the  results  of  observations  taken  under  the  direction  of  the 
Smithsonian  Institution. 

On  CJiart  /,  we  have  traced  the  yearly  isothermal  lines.  In  the  vicinity 
of  Manchester  there  is  a  small  area  where  the  yearly  mean,  48°,  is  greater 
than  in  any  other  part  of  the  state.  The  observations  extend  over  a 
period  of  fourteen  years  ;  hence,  they  ought  to  give  at  least  an  approxi 
mate  average.  An  extended  curve  of  47°,  of  which  Manchester  is  the 
centre,  lies  some  five  miles  beyond  the  first,  and  forms  an  entirely  isolated 
area.  In  contrast  with  this  comparatively  warm  area,  we  find  directly 
west  an  island  of  cold  with  the  isotherm  of  42°,  occupying  Dublin,  Nel 
son,  Stoddard,  and  parts  of  the  adjoining  towns.  The  isotherm  of  46° 
begins  at  the  state  line  in  New  Ipswich,  runs  northward,  then  turns 
south  of  east,  crosses  the  Merrimack  at  Thornton's  Ferry,  and  strikes  the 
coast  at  Portsmouth  ;  thence  it  is  deflected  northward  in  a  great  curve  that 
passes  above  Lake  Winnipiseogee,  and  returns  to  the  coast  at  the  mouth  of 
the  Piscataqua  river.  The  isotherm  of  45°  passes  through  Dover,  runs 
northward  near  the  state  line,  and  crosses  into  Maine  from  Effingham  ; 
the  other  end  of  it  begins  at  South  Charlestown,  is  deflected  southward 
through  Francestown,  then  runs  northward  nearly  parallel  with  the 
Merrimack,  passes  around  Newfound  lake  above  Squam,  thence  through 
Tamworth,  Madison,  and  Eaton,  connecting  with  the  other  part  of  it  in

Maine.  The  isotherm  of  44°  on  the  west,  is  a  sharpe  curve  beginning 
at  North  Charlestown,  and  it  has  its  further  limit  in  Danbury.  On  the 
eastern  border  of  the  state  there  is  a  short  curve  on  the  Saco  in  Conway. 
The  isotherm  of  43°  is  similar  in  shape  to  that  of  44°,  but  is  some  ten 
miles  northward. 

The  isotherm  of  42°  begins  on  the  Connecticut  in  Plainfield,  and 
extends  eastward,  but  is  soon  deflected  northward,  passes  above  the  White 
Mountains,  through  Randolph,  Gorham,  and  Shelburne.  The  isotherm 
of  41°  is  just  below  Hanover.  Westward  in  Vermont  it  is  deflected 
southward  ;  but  in  New  Hampshire  it  is  nearly  parallel  with  42°,  except 
that  from  Lisbon  a  branch  goes  almost  directly  north  to  Lunenburg,  Vt. 
The  isotherm  of  40°,  the  lowest  mean  average  in  the  settled  portions  of 
the  state,  begins  near  North  Stratford,  and  probably  extends  eastward  to 
Umbagog  lake.  As  we  ascend  the  mountains  the  mean  annual  tempera 
ture  decreases  rapidly,  so  that  on  the  summit  of  Mt.  Washington  we  have 
an  isotherm  of  25°. 

Chart  II.  Referring  to  chart  II,  we  have  isotherals,  or  lines  of  equal 
summer  temperature  ;  and  isochimenals,  or  lines  of  equal  winter  tem 
perature.  For  the  isotherals,  we  have  a  small  area  about  Manchester, 
included  within  the  line  of  70°;  there  is  also  an  isotheral  of  70°,  extend 
ing  along  the  northern  border  of  Lake  Winnipiseogee,  thence  through 
Ossipee  to  the  line  of  Maine.  The  isotheral  of  69°  is  below  Rochester, 
and  there  is  a  more  extended  area  of  the  same  through  Tarn  worth,  Madi 
son,  and  Eaton.  The  isotheral  of  68°  corresponds  with  the  isotherm  of 
47°.  The  curve  of  67°  is  the  most  variable  of  all  the  isotheral  lines. 

It  begins  at  the  Connecticut,  near  Claremont,  is  deflected  southward 
to  Francestown,  then  northward  to  Barnstead,  then  southward  again  as 
far  as  Exeter,  when  it  turns  north  and  passes  between  Dover  and  Great 
Falls.  The  curve  of  66°  begins  on  the  coast  near  Portsmouth,  and 
passes  up  the  Piscataquis  to  Dover,  where  it  is  deflected  eastward. 

The  isotheral  of  65°  passes  up  the  river  from  Hanover,  thence  up  the 
Ammonoosuc, — makes  a  sharp  curve  to  the  Connecticut,  at  Lancaster, 
then  runs  through  Randolph,  Gorham,  and  Shelburne  ;  that  of  64°  runs 
through  Stoddard,  Nelson,  Dublin,  and  Peterborough;  that  of  63°  begins 
in  North  Littleton,  goes  northward  through  Lunenburg,  Vt.,  and  then  is 
deflected  eastward  and  across  New  Hampshire,  near  the  Grand  Trunk 


128  PHYSICAL    GEOGRAPHY. 

Railway.  The  isotheral  of  62°  is  in  the  towns  of  Colebrook,  Dixville, 
and  Errol;  and  that  of  47°  touches  the  top  of  Mt.  Washington. 

The  general  direction  of  the  isochiraenal  lines  are  the  same  as  those  of 
the  isotheral.  We  have  an  island  of  cold  on  the  line  between  Cheshire 
and  Hillsborough  counties,  a  warm  area  in  the  vicinity  of  Manchester,  a 
gradual  increase  of  the  cold  inland  from  the  ocean  at  Portsmouth,  and 
the  same  deflection  northward, — but  not  to  so  great  a  degree, — of  the 
lines  beginning  at  the  Connecticut.  The  marked  conformity  of  the 
isochimenals  of  19°,  17,°  and  16°,  with  the  isotherals  of  65°,  63°,  and 
62°,  is  quite  remarkable. 

Cliart  III.  We  have  here  represented  the  entire  annual  aqueous  pre 
cipitation.  The  area  of  greatest  precipitation  is  in  the  central  portion 
of  the  state,  in  the  vicinity  of  Newfound  lake,  and  it  extends  north  at 
least  as  far  as  Ashland,  and  southward  probably  as  far  as  Franklin.  The 
rain-fall  in  this  area,  including  melted  snow,  is  46  inches.  There  is  an 
area  of  45  inches  from  Hooksett  southward  toward  the  state  line,  and  the 
table  would  give  us  a  small  area  in  the  vicinity  of  West  Enfield ;  but,  as 
there  seems  to  be  some  doubt  as  to  the  accuracy  for  that  locality,  we  have 
omitted  it  on  the  chart.  In  the  south-west  part  of  the  state,  below  a  line 
from  Claremont  and  extending  to  a  point  just  north  of  Concord,  there  is 
a  large  area  where  the  precipitation  is  43  inches.  There  is  an  area 
of  42  inches  north  of  Claremont,  perhaps  ten  miles  in  width,  extending 
to  the  Merrimack  river,  thence  northward  along  the  west  side  of  Lake 
Winnipiseogee,  when  the  area  widens  so  that  it  includes  almost  the  whole 
portion  of  the  state  north  of  the  lake  to  a  line  above  the  Grand  Trunk 
Railway.  In  the  north  part  of  the  state,  above  42,  there  is  an  area  of 
41  inches  extending  across  the  state,  and  having  a  width  of  about  twenty 
miles.  There  is  another  small  area  of  41  inches,  extending  from  Bath  in 
a  curve  southward  as  far  as  Plainfield.  Between  this  and  the  Connec 
ticut,  embracing  a  part  of  Orford,  Lyme,  and  Hanover,  there  is  an  area 
where  the  precipitation  is  only  a  little  more  than  40  inches.  Also,  the 
whole  portion  of  the  state  north  of  Stratford  is  included  in  the  area  of  40 
inches.  On  the  sea-coast,  at  least  in  the  vicinity  of  Portsmouth,  the  rain 
fall  is  less  than  in  any  other  part  of  the  state,  being  35  inches, — but  it 
increases  as  we  go  inland.  At  Dover  there  are  36  inches,  and  at  Wolfe- 
borough  38.  Since  the  distribution  of  rain-fall  depends  in  a  measure  on

THE  PHENOMENA  OBSERVED  ON  Mxs.  MOOSILAUKE  AND  WASHINGTON. 

In  the  summer  of  1869,  I  proposed  to  Prof.  Hitchcock  to  occupy  the 
summit  of  Mt.  Washington  the  following  winter,  for  the  purpose  of  taking 
meteorological  observations.  He  heartily  approved  of  the  undertaking, 
and  made  an  effort  to  secure  a  building  on  the  summit  of  that  mountain. 
In  this,  however,  he  failed ;  but  he  did  obtain  permission  for  me  to  occupy 
a  building  on  the  summit  of  Moosilauke.  In  late  autumn,  preparations 
were  made,  and  on  the  last  day  of  the  year  of  1869,  with  Mr.  A.  F. 
Clough  as  photographer,  I  ascended  this  mountain,  and  remained  there 
during  the  January  and  February  following.  The  expedition  was  carried 
out  chiefly  at  my  own  expense.  We  found  out  many  things  that  were 
novel  and  interesting,  and  some  that  were  new  to  science.  The  beautiful 
frost-work  of  our  mountain  summits  was  here  for  the  first  time  photo 
graphed  and  described ;  and  we  experienced  winds  of  greater  velocity 
than  had  ever  before  been  measured. 

Our  observations  here  made  us  still  more  desirous  of  spending  a  winter 
on  Mt.  Washington.  This  we  were  able  to  do  the  following  winter, 
through  the  cooperation  of  Prof.  Hitchcock,  Mr.  S.  A.  Nelson,  the  U.  S. 
Signal  Service,  and  the  seventy-five  individuals  and  firms,  besides  railroad 
corporations,  that  furnished  material  aid.  The  mountain  has  since  been 
occupied  by  the  Signal  Service,  and  last  summer  a  building  was  erected 
for  the  use  of  the  observers.

FROST-WORK. 

The  frost-work  is  the  most  remarkable  phenomenon  of  our  mountain 
summits.  It  is  difficult  to  convey,  in  words,  any  idea  of  its  wonderful 
form  and  beauty.  It  was  not  easy,  at  first,  to  understand  how  it  could  be 
formed ;  but  we  are  able  now  to  give  a  plausible  theory  to  account  for 
this  the  most  extraordinary  of  all  the  handiwork  of  Nature.  It  is  very 
rarely  formed  except  when  the  wind  is  at  some  point  between  north  and 
west,  and  only  when  there  are  clouds  on  the  mountains.  It  begins  with 
mere  points  on  everything  the  wind  reaches, — on  the  rocks,  on  the  rail 
way,  and  on  every  part  of  the  buildings,  even  on  the  glass.  On  the  south 
side  of  the  buildings  and  the  high  rocks  it  is  very  slight,  as  the  wind 
reaches  there  only  in  eddying  gusts.  When  the  surface  is  rough,  the 
points,  as  they  begin,  are  an  inch  or  more  apart ;  when  smooth,  it  almost 
entirely  covers  the  surface  at  the  very  beginning ;  but  soon  only  a  few 
points  elongate,  so  that  on  whatever  surface  it  begins  to  form,  it  has  soon 
everywhere  the  same  general  appearance,  presenting  the  same  beautiful, 
feathery-like  forms. 

"  Thus  Nature  works,  as  if  defying  art ; 
And  in  defiance  of  her  rival  powers, 
Performing  such  inimitable  feats, 
As  she,  with  all  her  rules,  can  never  reach." 

In  going  up  Mt.  Washington,  we  do  not  see  the  frost-work  until  we  get 
above  the  present  limit  of  the  trees.  It  is  nearly  a  mile  above  before  it 
is  seen  in  its  characteristic  forms,  and  it  is  only  immediately  about  the 
summit  that  it  presents  its  most  attractive  features.  On  all  our  moun 
tains  north  of  latitude  43°  50',  that  are  more  than  thirty-five  hundred 
feet  in  height,  it  can  be  seen  extending  down  to  a  certain  line,  and  this 
line  extends  along  the  whole  mountain  range.  Everywhere  it  appears  to 
be  at  the  same  elevation.  We  notice  that  it  always  forms  towards  the 
wind,  never  from  it ;  and  the  rapidity  with  which  it  forms,  and  the  great 
length  of  the  horizontal  masses,  are  truly  wonderful.  On  the  piles  of 
stones  south  of  the  house,  the  horizontal  masses  are  sometimes  five  and 
six  feet  in  length.  On  the  southern  exposures,  instead  of  the  frost-work, 
especially  on  the  telegraph  poles  by  the  railway,  there  are  only  masses  of 


CLIMATOLOGY    OF    NEW    HAMPSHIRE.  13! 

pure  ice,  which  have  always  a  peculiar  hue  of  greenish  blue ;  and  there  is 
a  striking  contrast  between  this  and  the  pure  white  of  the  frost-work  on 
the  side  opposite.  When  the  thermometer  ranges  from  25°  to  30°,  and 
the  wind  is  southward,  ice  often  forms  to  the  thickness  of  a  foot  or  more 
on  the  telegraph  poles  near  the  summit.  These  icy  masses  are  formed 
evidently  by  the  condensation  of  the  vapor  of  the  atmosphere.  The  frost 
work  is  also  formed  by  the  condensation  of  vapor,  but,  besides  the  vapor, 
the  air  must  be  filled  with  very  minute  spicuke  of  ice.  As  the  vapor 
condenses,  these  are  caught,  and  thus  the  horizontal,  feathery  masses  are 
formed.  This  accounts  for  the  facts  that  we  have  observed,  namely,  that 
it  forms  when  the  wind  is  northward,  and  always  towards  the  wind. 

Fig.  1 6  will  give  a  general  idea  of  the  appearance  of  the  Tip-top  house 
when  the  frost-work  has  formed  to  a  thickness  of  two  or  three  feet  on 
the  build  in  2:  and  the  rocks. 


Fig.   1 6. — TIP-TOP   HOUSE   IN  WINTER. 


The  beginning  of  the  frost-work  is  shown  in  the  accompanying  helio- 
type  entitled  Frost  Feathers.  Here  they  are  formed  on  the  surface  of  a 
rock.  The  longest  points  are  ten  inches  in  length,  and  each  presents 


132  PHYSICAL    GEOGRAPHY. 

serrated  and  feathery  edges.  This  view  was  almost  the  very  first  ever 
taken  of  this  peculiar  form  of  snow-ice;  and  had  it  not  been  for  the 
self-denial  of  my  late  friend  Mr.  A.  F.  Clough,  and  his  intense  love  of 
the  grand  and  beautiful  in  nature,  it  is  probable  that  many  years  would 
have  elapsed  before  another  artist  would  have  had  the  inclination,  much 
less  the  courage,  to  encounter  the  difficulties  and  dangers  that  presented 
themselves  to  a  person  who  contemplated  spending  a  winter  on  the 
summit  of  one  of  our  highest  mountains. 

In  the  illustration  entitled  Snow-ice,  the  frost  feathers  are  elongated, 
and  form  immense  feathery  masses  two  or  three  feet  in  length.  On 
account  of  the  boards  being  loose,  it  has  fallen  off  from  the  side  of  the 
building;  but  this  is  an  advantage,  since  the  corner  of  the  building  can  be 
seen,  and  one  can  get  a  better  idea  of  its  form  and  length.  The  view  was 
taken  on  the  summit  of  Mt.  Washington  by  Mr.  B.  W.  Kilburn,  in  1872, 
who,  by  his  perseverance  and  skill,  has  made  our  Alpine  scenery  known 
to  tens  of  thousands  who  have  never  visited  the  mountains. 

THE  WEATHER  AT  HIGH  ALTITUDES. 

As  to  the  extraordinary  weather  on  our  mountains  in  winter,  the  follow 
ing  description  is  a  typical  illustration  of  two  days  on  Moosilauke : 

On  the  first  day  of  January  the  sun  rose  clear.  We  were  above  the  clouds,  and  a 
grander  spectacle  one  does  not  often  behold.  The  clouds  seemed  to  roll  and  surge  like 
the  billows  of  the  ocean.  They  were  of  every  dark  and  of  every  brilliant  hue :  here 
they  were  resplendent  with  golden  light,  and  there  they  were  of  silvery  brightness ; 
here  of  rosy  tints,  there  of  sombre  gray ;  here  of  snowy  whiteness,  there  of  murky 
darkness  ;  here  gorgeous  with  the  play  of  colors,  and  there  the  livid  light  flashes  deep 
down  into  the  gulfs  formed  by  the  eddying  mist,  while 

"  Far  overhead 

The  sky,  without  a  vapor  or  a  stain, 
Intensely  blue,  even  deepened  into  purple 
When  nearer  the  horizon  it  received 
A  tincture  from  the  mist  that  there  dissolved 
Into  the  viewless  air.     .     .     .     The  sky  bent  round 
The  awful  dome  of  a  most  mighty  temple, 
Built  by  Omnipotent  hand  for  nothing  less 
Than  infinite  worship.     So  beautiful, 
So  bright,  so  glorious  !  Such  a  majesty 

In  yon  pure  vault !     So  many  dazxling  tints 
In  yonder  waste  of  waves." 


•  •'" 


CLIMATOLOGY    OF    NEW    HAMPSHIRE.  133 

But  above  all  these  clouds,  these  flashes  of  light,  this  darkness,  rises  in  stately  grandeur 
the  summit  of  Mt.  Washington,  "sublime  in  its  canopy  of  snow ;"  and  Lafayette,  with 
a  few  peaks  of  lesser  altitude,  glitters  in  the  bright  sunlight.  As  the  sun  rises  higher, 
the  picture  fades  away,  and  the  whole  country  is  flooded  with  light.  Did  this  grandeur, 
this  magnificence,  this  grand  display  of  lights,  of  shadows,  and  shades, — these  clouds, 
so  resplendent,  so  beautiful, — portend  a  storm?  In  the  evening  the  wind  changed  to 
the  south-east,  and  increased  in  velocity. 

At  daylight,  on  the  second,  it  was  snowing.  This  soon  changed  to  sleet,  and  then  to 
rain  ;  and,  at  8  A.  M.,  the  velocity  of  the  wind  was  70  miles  per  hour.  At  12,  there  was 
a  perfect  tempest.  Although  the  wind  was  so  fearful,  yet  Mr.  Clough  was  determined 
to  know  the  exact  rate  at  which  it  was  blowing.  By  clinging  to  the  rocks  he  succeeded 
in  reaching  a  place  where  he  could  expose  the  anemometer,  and  not  be  blown  away  him 
self.  He  found  the  velocity  to  be  97^  miles  per  hour, — the  greatest  velocity,  until  that 
time,  ever  recorded.  When  he  reached  the  house  he  was  thoroughly  saturated,  the 
wind  having  driven  the  rain  through  every  garment,  although  they  were  of  the  heaviest 
material,  as  though  they  were  made  of  the  lightest  fabric.  During  the  afternoon,  the 
rain  and  gale  continued  with  unabated  violence.  The  rain  was  driven  through  every 
crack  and  crevice  of  the  house,  and  the  floor  of  our  room  was  flooded.  So  fierce  was 
the  draught  of  the  stove,  that  the  wind  literally  took  away  every  spark  of  fire,  leaving 
only  the  half-charred  wood  in  the  stove  ;  and  it  was  with  the  greatest  difficulty  that  we 
succeeded  in  rekindling  it.  During  the  evening,  the  wind  seemed  to  increase  in  fury ; 
and  although  the  window  was  somewhat  protected,  yet  nearly  every  glass  that  was 
exposed  was  broken  by  the  pressure  of  the  gale.  As  the  lights  were  broken,  the  fire 
was  again  extinguished ;  and  even  my  hurricane  lantern  was  blown  out  as  quickly  as  if 
the  flame  had  been  unprotected.  Darkness,  if  not  terror,  reigned  ;  but  calmness,  with 
energy,  are  requisites  for  such  an  occasion,  and,  fortunately,  they  were  not  wanting 
now.  Our  necessities  quickly  showed  us  what  to  do.  By  nailing  boards  across  the 
windows,  and  by  the  use  of  blankets,  we  stopped  the  openings  the  wind  had  made. 
After  9  p.  M.  there  were  occasional  lulls  in  the  storm,  and  by  12  it  had  considerablv 
abated,  at  least  enough  to  bring  on  that  depression  that  naturally  succeeds  a  period  of 
intense  excitement; — so  we  willingly  yielded  ourselves  to  sleep,  to  dream  of  gentle 
zephyrs  and  sunny  skies. 

•  Although  as  a  rule  rains  in  winter  are  not  common  on  the  summits  of 
our  high  mountains,  yet  observations  thus  far  show  that  every  third 
winter  they  may  be  quite  frequent. 

As  already  indicated,  the  clouds  are  often  spread  out  in  a  thin  stratum 
over  a  large  area,  and  we  look  forth  upon  an  illimitable  sea  of  mist  glit 
tering  in  the  sunlight,  while  every  peak,  except  that  on  which  we  stand, 
is  concealed  by  clouds.  So  it  is  not  uncommon  for  it  to  be  a  dark  day  in 
the  valleys,  while  on  the  summit  of  the  mountain  we  are  in  the  bright 


134  PHYSICAL    GEOGRAPHY. 

sunlight.  Sometimes  the  clouds  are  two  thousand  feet  below  the  summit 
of  Mt.  Washington ; — in  that  case,  innumerable  mountain  peaks  protrude, 
and  seem  like  islands  in  an  ocean  bounded  only  by  the  sky.  The  forma 
tion  and  the  dissolving  of  clouds  is  an  interesting  feature.  It  often 
happens  that  the  whole  country  westward  is  covered  with  clouds,  but 
when  they  have  passed  the  ridge  running  directly  south  from  Mt.  Wash 
ington,  they  are  instantly  dissolved,  never  passing  a  certain  point, 
although  moving  at  the  rate  of  fifty  or  sixty  miles  per  hour,  when  that 
point  is  reached.  In  spring  and  summer,  instead  of  these  horizontal 
layers,  the  clouds  assume  cumulose  forms,  and  from  the  mountain  they 
can  be  seen  rising  vertically  thousands  of  feet  in  an  incredibly  short 
space  of  time.  During  the  steady  cold  weather  of  winter,  the  upper 
clouds  \vere  never  seen  to  move  except  in  the  same  direction  as  the  wind 
on  the  summit  of  the  mountain. 

WIND  AND  RAIN. 

Of  all  phenomena,  the  wind  is  the  most  terrific.  Usually  during 
periods  of  storm,  the  wind  increases  steadily  in  velocity  until  it  reaches 
its  culmination :  then  there  are  lulls,  at  first  only  for  an  instant,  and  these 
continually  lengthen  until  the  storm  ceases.  The  greatest  velocity  that 
has  been  measured  is  140  miles  per  hour;  and  during  one  night  the  mean 
of  four  observations  was  128  miles.  The  most  remarkable  fact  in  relation 
to  the  wind  is  the  great  velocity  on  the  summit  when  there  is  a  calm  at 
the  base.  One  observation  shows  that  there  was  a  wind  of  96  miles  per 
hour  on  the  summit,  when,  at  the  depot  of  the  Mt.  Washington  Railway, 
2,677  feet  below,  there  was  not  wind  enough  to  move  the  anemometer. 
The  observations  were  taken,  under  the  direction  of  the  Wrar  depart 
ment,  during  the  month  of  May,  1872,  at  7  A.  M.,  9  A.  M.,  12  M.,  4  p.  M.,  and 
9  P.  M. 

In  general,  winds  of  very  great  velocity  are  usually  limited  to  winter, 
and  to  the  time  when  there  are  clouds  on  the  mountain.  The  prevailing 
winds  for  the  entire  year  are  west  and  north-west.  It  is  a  noticeable  fact 
that,  while  the  northerly  and  westerly  winds  have  a  much  greater  velocity 
on  the  summit  than  below,  the  southerly  winds  have  frequently  a  greater 
velocity  five  hundred  or  a  thousand  feet  below  than  on  the  summit.  In 
Fig.  17,  the  curve  represents  the  velocity  of  the  wind.  Fig.  18  shows 


CLIMATOLOGY    OF    NEW    HAMPSHIRE.

the  rise  and  fall  of  the  barometer.     The  correspondence  between  the  two 
is  very  striking,  especially  during  periods  of  great  disturbance.

AOJJEOUS  PRECIPITATION. 

The  observations  for  one  year  give  the  amount  of  aqueous  precipitation 
as  55  inches,  and  it  is  confined  mainly  to  summer  and  autumn, — the  entire 
precipitation  for  winter  and  spring  being  given  as  only  about  eight  inches, 
leaving  47  inches  for  summer  and  autumn.  There  is  no  means  of  deter 
mining  the  actual  amount  of  frost-work  and  snow,  but  we  know  that  the 


136  PHYSICAL    GEOGRAPHY. 

snow-fall  is  very  slight  during  autumn  and  winter,  the  snow-cloud  being 
below  the  summit ;  but  in  spring,  when  showers  become  frequent  in  the 
valleys,  there  are  invariably  heavy  falls  of  snow  on  the  mountain.  During 
a  thunder-storm  in  April,  when  the  thunder  could  be  heard  and  the  light 
ning  seen,  we  were  having  one  of  the  thickest  snow-storms  of  the  season. 
Nearly  all  the  optical  phenomena  seen  elsewhere  on  mountain  summits 
have  been  observed  on  Mt.  Washington.  Rainbows,  with  three  supernu 
merary  bows,  have  been  seen  for  hours  on  the  clouds ;  coronas,  of  large 
and  small  dimensions ;  anthelia  or  glories  of  light,  the  prismatic  circles 
surrounding  the  shadow  cast  far  out  on  the  clouds ;  halos,  and  parhelia. 
The  spectre  of  the  Brocken,  though  rare,  was  seen  by  Mr.  S.  A.  Nelson. 

DIAGRAMS. 

Diagram  I  shows  the  fluctuations  in  the  annual  rain-fall  in  the  Atlantic 
states, — Maine  to  Maryland, — from  1805  to  1867.  From  the  fluctuations 
as  shown  in  this  diagram,  there  are  groups  of  years  of  unusual  amount 
of  rain,  followed  by  groups  of  years  of  drouth ;  and,  on  the  whole,  it  indi 
cates  an  increase  of  rain.  The  figures  on  the  left  are  the  per-centage 
of  the  mean  amount. 

Diagram  II  shows  the  fluctuations  in  the  annual  rain-fall  in  the  upper 
Connecticut  valley,  from  observations  taken  at  Lunenburg,  Vt.  This 
shows  similar  groups  of  years.  An  unusual  amount  of  rain-fall  does  not 
necessarily  imply  that  it  was  distributed  throughout  the  year,  so  that 
there  was  no  drouth  in  summer;  for,  while  the  amount  of  rain  in  1871 
was  above  the  average,  yet  the  summer  of  that  year  was  regarded  as  very 
dry. 

Diagram  III  shows  the  fluctuations  in  the  annual  snow-fall  at  the  same 
locality,  and  by  the  same  observer,  as  in  Diagram  II.  The  fluctuation, 
however,  is  greater  than  in  the  rain-fall;  for  the  greatest  amount,  167.5 
inches,  is  more  than  twice  as  much  as  the  mean,  83.1  inches,  and  the 
least  amount,  41  inches,  is  less  than  half  the  mean;  yet  there  are  similar 
groups  of  years,  though  at  no  time  does  it  show  more  than  three  consec 
utive  years,  when  the  amount  was  greater  than  the  mean. 

Diagram  IV  shows  the  annual  fluctuations  in  rain-fall  at  Lake  Village 
from  1857  to  J873.  The  observations  were  taken  under  direction  of  the 
Lake  Company.

Diagram  Fis  a  comparison  of  the  extreme  maximum  and  minimum 
temperatures  of  the  7  A.  M.,  2  p.  M.,  and  9  P.  M.  observations  at  Claremont 
and  Stratford  for  1867  and  1868.  These  places  were  selected  for  compari 
son,  since  Claremont  is  the  most  southern  point  in  the  Connecticut  valley 
where  observations  have  been  taken,  and  Stratford  the  most  northern. 
It  is  noticeable  that,  while  the  minimum  of  Stratford  is  less  than  at  Clare 
mont,  the  maximum  is  greater  at  Stratford  than  at  Claremont.  This  is 
the  general  rule,  though  there  are  exceptions  to  both. 

Diagram  VI  is  a  comparison  of  the  monthly  mean  temperatures  of 
Exeter,  Claremont,  and  Stratford  for  1864.  It  will  be  observed  that,  in 
the  extreme  maximum  and  minimum,  the  difference  is  greatest  in  winter 
and  least  in  summer;  but  in  the  monthly  mean,  that  the  difference 
between  Claremont  and  Stratford  is  greatest  in  summer  and  least  in 
winter. 

Diagram  VII  is  a  comparison  of  the  monthly  mean  temperatures  of 
Mt.  Washington  and  Lunenburg,  Vt. 

Diagram  VIII  is  a  comparison  of  the  maximum  and  minimum  tem 
peratures  at  Exeter,  Manchester,  Claremont,  North  Bridgeton,  Me.,  and 
St.  Johnsbury,  Vt.,  during  the  cold  period  of  January,  1861. 

Diagram  IX  is  a  comparison  of  maximum  and  minimum  mean  temper 
atures  for  the  cold  period  of  January,  1871,  of  Mt.  Washington,  Tamworth, 
Contoocookville,  Stratford,  and  Whitefield. 

Diagram  X  shows  graphically  the  difference  in  the  velocity  of  the  wind 
at  the  station  on  the  summit  of  Mt.  Washington,  and  a  station  at  the 
depot  of  the  Mt.  Washington  Railway,  2,677  ^ee^  below  the  summit.  The

CHAPTER    VI, 


THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING. 


BY  E.  T.  QUIMBY,  A.M., 

PROFESSOR   OF    MATHEMATICS   AND    CIVIL    ENGINEERING,   DARTMOUTH    COLLEGE. 


>HE  object  of  this  paper  is  to  explain  the  facts  of  terrestrial  mag 
netism,  so  far  as  they  relate  to  the  use  of  the  magnetic  needle  by 
the  surveyor,  with  particular  reference  to  the  state  of  New  Hampshire. 
It  will  not  therefore  be  necessary  to  describe  the  construction  and  use  of 
the  instruments  by  means  of  which  these  facts  have  been  observed,  nor 
to  discuss  the  formulae  for  the  reduction  of  the  observations.  Those 
who  wish  to  make  a  thorough  examination  of  this  subject  are  referred  to 
the  works  of  Airy,  Walker,  and  others,  and  to  the  reports  of  the  United 
States  Coast  Survey,  under  whose  auspices  extensive  magnetic  observa 
tions  have  been  and  are  still  being  made  in  various  parts  of  our  country. 
It  may  seem  of  little  importance  to  reproduce  what  has  been  so  long 
known,  when  nothing  specially  new  can  be  added ;  but  an  examination  of 
the  records  of  surveys  made  within  the  last  fifty  years  will  show  that 
there  is  need  either  of  more  general  knowledge  on  this  subject,  or  of  a 
better  use  of  what  is  known.  It  is  quite  unusual  to  find  in  any  of  these 
records  the  slightest  reference  to  magnetic  declination ;  and  there  is 
reason  to  believe  that  surveyors  sometimes  rely  too  implicitly  upon  the 
needle  in  retracing  old  lines  by  their  former  magnetic  bearings.  It  will 
appear  by  the  behavior  of  the  needle  that,  while  it  is  a  valuable  aid,  it  can 


148  PHYSICAL    GEOGRAPHY. 

never  be  depended  on  for  such  purposes,  and  should,  in  all  cases,  be  used 
with  caution,  and  only  when  extreme  accuracy  is  not  required. 

It  is  well  known  that  a  bar  (not  magnetic)  suspended  from  its  centre  of 
gravity  will  remain  in  any  position  in  which  it  may  be  placed,  unless  dis 
turbed  by  some  extraneous  force ;  but  if  the  bar  be  made  of  steel,  and 
magnetized,  it  will  assume  a  definite  direction,  and,  when  disturbed,  will 
invariably  return  to  the  same  direction  when  the  disturbing  force  ceases. 
This  directive  property  of  the  magnet  was  known  to  the  Chinese,  and 
probably  in  Europe,  as  early  as  the  twelfth  century;  and  the  magnetic 
needle  has  from  that  time  been  used  to  guide  ships  upon  the  seas,  and 
for  exploring  and  other  purposes  upon  the  land.  This  needle  consists  of 
a  slender  magnetized  steel  bar,  balanced  upon  a  pivot  at  a  point  consider 
ably  above  its  centre  of  gravity,  that  it  may  retain  its  horizontal  position ; 
and,  when  left  free  to  turn  upon  its  pivot,  it  comes  to  rest,  by  the  action 
of  the  earth's  magnetism,  approximately  in  the  plane  of  a  meridian :  hence 
one  end  is  called  the  north  pole,  and  the  other  the  south  pole  of  the 
magnet,  and  a  vertical  plane  through  the  needle  is  termed  the  magnetic 
meridian.  It  is  not  certain  at  what  time  the  deviation  of  the  magnetic 
from  the  true  meridian  (called  the  declination  of  the  needle)  first  became 
known,  but  it  is  evident  that  it  could  not  have  been  long  after  the 
directive  property  itself  was  discovered.  There  is,  however,  no  reliable 
record  of  any  experiments  to  determine  the  amount  of  this  declination 
prior  to  the  discovery  of  America,  although  it  is  probable  such  experiments 
were  made.  It  seems  likely,  also,  that  this  declination  was  previously 
supposed  to  be  constant,  or  nearly  so,  for  all  times  and  places, — as  Colum 
bus  and  his  sailors  were  not  a  little  surprised,  and  some  of  them  alarmed, 
on  the  1 3th  of  September,  1492,  to  find  that  the  needle,  which  at  the 
commencement  of  their  voyage  pointed  east  of  north,  had  changed  to 
west  of  north.  Since  that  time  the  interest  in  terrestrial  magnetism, 
among  scientific  men,  has  been  increasing ;  and  observations,  at  first  with 
instruments  rudely  constructed,  but  more  recently  with  those  of  extreme 
delicacy,  have  revealed  facts,  a  knowledge  of  which  is  important  to  every 
one  using  the  magnetic  needle. 

To  make  the  statement  of  these  facts  plain,  let  us  recur  to  our  magnet 
ized  bar  which  we  supposed  to  be  suspended  from  its  centre  of  gravity. 
This  magnet,  if  left  free  to  turn  about  the  point  of  suspension  in  all 


THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  149 

directions,  will  take  a  position  in  the  magnetic  meridian  which  (if  the 
observation  be  taken  at  Hanover)  will  deviate  from  the  true  meridian 
about  11°,  the  north  end  of  the  magnet  turning  to  the  west  of  north. 
Moreover,  also,  it  will  incline  to  the  horizon,  the  north  pole  dipping  down 
ward  at  an  angle  of  about  75°  30'.  This  is  called  the  inclination  or  dip 
of  the  needle.  It  becomes  necessary,  therefore,  in  studying  the  phenom 
ena  of  terrestrial  magnetism,  to  make  use  of  two  instruments, — one  for 
observations  upon  the  declination,  and  the  other  upon  the  dip  of  the 
needle.  In  the  former,  the  needle  hangs  horizontally  in  a  stirrup  sus 
pended  by  a  fibre  of  untwisted  silk,  which  leaves  it  free  to  turn  in  a 
horizontal  plane  with  the  least  possible  resistance ;  while  the  latter,  called 
the  dipping  needle,  is  balanced  upon  a  horizontal  axis,  and  is  free  to  turn 
only  in  a  vertical  plane,  and  when  in  use  must  have  its  axis  perpendicular 
to  the  plane  of  the  magnetic  meridian.  Besides  the  declination  and  dip, 
we  may  also  consider  the  intensity  of  terrestrial  magnetism,  by  which  is 
meant  the  amount  of  that  force  which  restores  the  needle,  when  dis 
turbed,  to  its  normal  direction.  This  element  is  of  so  little  practical 
importance  in  the  ordinary  use  of  the  needle,  that  it  may  be  passed 
briefly. 

Intensity  of  Terrestrial  Magnetism.  If  a  magnetic  needle, — suspended, 
as  mentioned  above,  by  a  fibre  of  silk, — be  drawn  out  of  the  magnetic 
meridian  by  bringing  near  it  another  magnet,  and  then  allowed  to  return 
by  removing  the  second  magnet  to  a  distance,  it  will  oscillate  for  a  time 
before  the  resistance  of  the  air  and  of  the  suspending  fibre  will  bring  it 
to  rest.  If  the  weight  and  dimensions  of  the  needle  are  accurately  known, 
and  the  number  of  oscillations  it  makes  in  a  given  time  be  observed,  it  is 
easy  to  compute  the  intensity  of  the  force  'which  actuates  it,  the  more 
rapid  oscillation  indicating  the  greater  force.  This,  however,  will  not 
represent  the  total  force  of  the  earth's  magnetism,  but  only  that  part  of  it 
which  tends  to  bring  the  needle  into  the  plane  of  the  magnetic  meridian, 
and  which  is  called  the  horizontal  intensity,  or  the  horizontal  component 
of  the  magnetic  force.  The  vertical  component  tends  to  draw  the  north 
end  of  the  needle  downward  (in  the  Northern  hemisphere),  causing  the  dip. 
The  actual  direction  of  the  force  of  terrestrial  magnetism  at  any  place  is 
the  same  as  that  of  a  magnetic  needle  suspended  from  its  centre  of' 
gravity,  and  free  to  move  in  all  directions,  or  of  the  dipping-needle  when

placed  in  the  plane  of  the  magnetic  meridian.  As  we  go  towards  the 
south,  the  vertical  component  of  this  force  diminishes,  and  the  horizontal 
component  increases,  as  will  be  seen  by  the  United  States  Coast  Survey 
chart  (p.  6)  showing  lines  of  equal  horizontal  intensity,  and,  also,  of 
equal  dip.  Neither  does  the  magnetic  intensity  remain  the  same  for  the 
same  place.  Observations  made  at  Washington,  D.  C.,  by  the  United 
States  Coast  Survey,  show  that  the  total  force  at  that  place  has  heretofore 
been  slightly  increasing,  while  at  the  present  time  it  is  nearly  stationary, 
or,  perhaps,  beginning  to  decrease.  Like  the  other  magnetic  elements, 
the  intensity  has  its  secular  period  of  change,  but  the  data  are  not  at 
present  sufficient  to  determine  that  period ;  and  even  if  it  were  known,  it 
would  be  of  no  practical  importance  to  the  surveyor. 

Magnetic  Dip.  When  the  dipping-needle  is  placed  in  the  plane  of  the 
magnetic  meridian, — that  is,  with  its  axis  at  right  angles  to  this  plane, — 
the  north  end  is  drawn  downwards,  making,  at  Hanover,  an  angle  with 
the  horizon  of  about  75°  30'.  If,  now,  we  carry  this  needle  to  the  south, 
we  find  the  dip  diminishing,  until,  near  the  equator,  we  reach  a  place  where 
it  is  zero.  We  may  then  trace  a  line,  approximately  east  and  west,  upon 
which  there  is  no  clip.  North  of  this  line  the  north  end  of  the  needle 
will  dip,  and  south  of  it,  the  south  end.  On  each  side  of  the  line  of  no 
dip,  we  may  trace  lines  of  equal  dip  called  isoclinic  lines.  These  lines 
are  shown,  so  far  as  they  have  been  determined  for  the  United  States, 
on  the  chart  previously  referred  to  (p.  6).  Going  northward,  the  dip 
increases,  till,  at  a  magnetic  pole,  the  needle  takes  a  vertical  position. 

The  magnetic  dip,  like  the  intensity,  is  slowly  changing,  as  continued 
observations  upon  the  dipping-needle  show.  Previous  to  1854,  it  was 
increasing  in  the  United  States,  and  since  that  date  it  has  diminished 
about  30'. 

-  The  use  of  the  magnetic  needle  in  surveying  does  not  require  special 
attention  to  the  dip.  It  is  only  necessary  to  place  upon  one  end  of  the 
needle  a  suitable  counterpoise  to  keep  it  in  a  horizontal  position,  since, 
when  balanced  before  being  magnetized,  it  will  always  require  such  a 
counterpoise  after  it  is  magnetized,  unless  used  upon  the  line  of  no  dip ; 
and,  when  balanced  for  one  latitude,  it  will  need  readjusting  if  taken  to  a 
different  latitude.  When  the  needle  is  once  properly  balanced  for  any 
place,  the  surveyor  need  give  no  further  attention  to  the  dip.

THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  153 

Magnetic  Declination.  As  an  instrument  for  the  determination  of  the 
true  bearings  of  lines,  it  is  evident  that  the  magnetic  needle  can  be  of 
little  value  except  as  we  are  able  to  determine  accurately  its  declination, 
or  the  angle  it  makes  with  the  true  meridian.  It  is  true  that,  when  only 
a  comparison  of  directions  is  required,  as  in  the  survey  of  a  field  to  deter 
mine  its  figure  and  area,  it  is  of  no  consequence  what  the  declination  is, 
provided  it  remains  the  same  during  the  progress  of  the  survey  and  for 
all  points  where  the  needle  is  used;  but  even  then,  to  make  the  survey 
useful  in  retracing  the  same  lines  at  a  future  time,  the  declination  should 
be  known  and  recorded. 

By  observations  upon  the  needle  of  a  well  constructed  magnetometer, 
the  following  facts  relating  to  the  declination  will  appear,  some  of  which 
will  be  indicated  even  by  the  ordinary  compass  needle. 

1.  The  declination  is  not  the  same  in  all  places. 

2.  For  a  given  place  it  is  subject  to  a  secular  change  of  unknown 
period,  but  requiring  at  least  several  hundred  years  for  its  completion. 

3.  It  has  a  diurnal  change,  with  a  maximum  and  minimum  for  each 
day. 

4.  It  has  also  an  annual  maximum  and  minimum,  changing  with  the 
seasons  of  the  year. 

5.  It  is  subject  to  irregular  disturbances,  being  more  or  less  affected  by 
every  meteorological  change. 

Discussing  these  in  their  order,  we  consider, 

i.  The  declination  in  different  places.  This  is  well  shown  by  the  chart 
of  the  world  (p.  8)  upon  which  lines  of  equal  declination,  called  isogonic 
lines,  are  drawn.  By  reference  to  this  chart  it  will  be  seen  that,  on  this 
continent,  a  line  of  no  declination  passes  in  a  north-westerly  and  south 
easterly  direction  near  Cleveland,  O.,  and  Raleigh,  N.  C.  At  all  places 
east  of  this  line,  the  declination  is  westerly, — that  is,  the  north  end  of  the 
needle  points  to  the  west  of  north ;  and  west  of  the  line  the  declination 
is  easterly.  The  map  of  New  Hampshire  and  Vermont,  herewith  given, 
shows  the  isogonic  lines  for  these  states,  as  delineated  by  the  United 
States  Coast  Survey.  By  observing  the  situation  of  a  place  with 
reference  to  these  lines,  the  declination  for  that  place  may  be  approxi 
mately  determined ;  but  while  they  may  be  considered  mainly  correct  for 
this  date  (January,  1874),  no  surveyor  should  rely  upon  them  for  the 

VOL.  I.       21 


154  PHYSICAL    GEOGRAPHY. 

declination  of  a  place,  when  it  is  possible  to  determine  that  declination 
by  a  direct  observation  upon  the  true  meridian. 

By  the  general  direction  of  these  lines  in  New  England,  it  appears 
that,  by  moving  north-westerly  or  south-easterly,  but  little  change  will 
be  noted  in  the  declination;  but  in  going  north  or  north-east  it  will 
increase,  and  diminish  in  going  south  or  south-west.  The  following 
declinations  were  observed  by  Dr.  T.  C.  Hilgard,  for  the  United  States 
Coast  Survey,  in  1873:

tion  at  that  place  is  1 1  °  30'.

2.  Secular  Variation  of  the  Declination.  The  line  of  no  declination 
and  the  other  isogonic  lines  are  not  fixed  in  position,  but  are  slowly  mov 
ing.  This  motion,  in  the  United  States,  is  at  the  present  time  for  the 
most  part  toward  the  south-west.  In  1801  the  line  of  no  declination 
passed  nearly  through  Annapolis,  Md.,  crossing  Lake  Erie  about  forty 
miles  from  Buffalo.  In  1850  it  had  gone  to  the  west  upon  our  coast  as  far 
as  Beaufort,  N.  C.,  and,  passing  west  of  Pittsburgh,  Penn.,  crossed  Lake 
Erie  near  its  centre.  In  1870  it  passed  very  nearly  through  the  cities  of 
Raleigh,  N.  C.,  and  Cleveland,  O.  At  the  present  time,  the  declination  is 
more  than  3°  upon  the  line  where,  in  1801,  it  was  o°.  The  influence 
which  causes  this  change  in  declination  is  passing  over  this  continent 
from  north-east  to  south-west,  as  will  be  seen  by  the  following  extract 
from  a  report  on  secular  changes  in  declination,  &c.,  by  C.  A.  Schott, 

*  Probably  too  small  on  account  of  local  attraction.

THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  155 

assistant  in  charge  of  the  computing  division,  United  States  Coast  Survey 
office,  Washington,  D.  C. : 

The  influence  which  produced  the  increase  of  magnetic  west  declination  on  our 
Atlantic  coast  was  first  recognized  in  the  north-east,  extending  itself  in  time  toward 
the  south-west.  The  minimum  west  declination  occurred  at  Portland,  Me.,  about  1765  ; 
at  Cambridge,  Mass.,  about  1783;  at  New  York,  about  1795  ;  at  Savannah,  Ga.,  about 
1817  ;  at  New  Orleans,  La.,  about  1831  ;  and  at  the  city  of  Mexico  about  1838,  appear 
ing  at  the  last  three  places  as  a  maximum  east  declination.  The  same  influence  will 
possibly  soon  reach  our  Pacific  coast,  where  at  present  the  east  declination  is  still 
slowly  on  the  increase.  Sub-periods  or  subordinate  waves  in  the  secular  change  have 
been  recognized  in  the  observed  declinations  at  Cambridge,  Mass.,  at  Hatboro',  Penn. 
(near  Philadelphia),  and  at  other  places ;  and  they  are  also  noted  in  the  observed  dips 
at  Washington,  and  Toronto,  Canada. 

Taking  this  view  of  the  subject,  the  phenomenon  of  the  secular  change  is  a  complex 
one ;  and  the  numerical  formulae  designed  for  expressing  it  must,  for  the  present, 
retain  their  tentative  and  hence  provisional  character ;  and  they  should  not  be  used 
(either  way)  much  beyond  the  time  for  which  they  are  supported  by  observations. 

The  declination  at  Hanover  in  1840  was  9°  20'  west,  and  the  annual 
increase  at  that  time  5 ' .2.  But  the  whole  change  since  then  is  only  2°, 
being  an  average  of  3 '.5  per  annum  ;  and  recent  observations  show  that 
the  annual  increase  during  the  last  decade  has  been  less  than  3'.  The 
present  rate  of  change  will  not  be  accurately  known  until  the  observa 
tions  made  in  September,  1873,  shall  be  repeated.  It  is  probably  not 
more  than  2'  or  2 '.5  per  annum,  which  indicates  a  probability  that  the 
westerly  declination  will  reach  a  maximum  here  about  the  close  of  the 
present  century.  If  this  estimate  should  prove  correct,  and  the  period 
of  decrease  should  be  as  long  as  that  of  increase,  the  time  required  for 
the  declination  to  pass  from  a  minimum  to  a  maximum  and  to  return  to 
the  minimum,  will  be  about  two  hundred  and  forty  or  two  hundred  and 
-fifty  years.  We  have  not,  however,  at  present,  sufficient  data  to  deter 
mine  this  period  with  accuracy,  nor  are  the  causes  which  produce  the 
change  well  known. 

The  amount  of  the  secular  variation  is  very  different  in  different  parts 
of  the  earth.  At  the  Cape  of  Good  Hope,  in  two  hundred  and  forty-six 
years,  ending  1850,  the  declination  had  changed  from  30' east  to  29°  iS',8 
west,  and  was  at  that  date  slightly  increasing.  This  shows  a  longer 
period  and  much  greater  change  than  in  the  United  States.  In  New 


156  PHYSICAL    GEOGRAPHY. 

England  the  whole  change  is  probably  between  6°  and  8°.  The  following 
declinations,  copied  from  the  United  States  Coast  Survey  Report  for 
1855,  were  observed  at  Cambridge,  Mass.,  and  show  the  change  at  that 
place  since  1708: 

1708 — 9°  oo'  west.  1782 — 6°  45'  west.  1840 —  9°  18'  west. 

1742 — 8°  oo'  west.  1783 — 6°  52'  west.  1842 —  9°  34'. 9  west. 

1757 — 7°  20'  west.  1788 — 6°  38'  west.  1844 —  9°  39'  west. 

1761 — 7°  14'  west.  1810 — 7°  30'  west.  1852 — ioc  08'  west. 

1763 — 7°  oo' west.  1835 — 8°  51' west.  1854 — 10°  39' west. 

1780 — 7°  02'  west.  •          1837 — 9°  09'  west.  1855 — 10°  54'  west. 

From  these  facts  will  appear  the  importance  of  recording,  with  the 
minutes  of  every  survey,  the  declination  of  the  needle  at  the  time  and 
place.  To  do  this  the  surveyor  must  know  the  declination,  which  he 
cannot  do  without  some  trouble  and  labor.  He  must  frequently  try  his 
compass  by  some  well  established  meridian,  which,  if  he  cannot  find 
already  determined,  he  must  locate  for  himself.  Neither  should  he  lose 
any  opportunity  to  take  the  bearing  of  any  old  line  whose  former  bearing 
he  may  find  in  the  record  of  some  previous,  perhaps  the  original,  survey. 
By  continuing  such  observations,  he  will  learn  not  only  the  amount  of 
the  declination  at  the  time  of  the  former  survey,  but,  also,  its  rate  of 
change,  and  the  whole  change  that  has  occurred  since  the  running  of  the 
old  lines  with  which  he  has  compared  his  needle ;  and  he  will  thus  gain 
information  which  will  render  his  services  invaluable  in  disputes  relating 
to  division  lines. 

3.  Diurnal  change  in  the  Declination.  If  hourly  observations  be  made 
upon  the  delicately  suspended  needle  of  a  magnetometer,  or,  still  better, 
if  we  use  a  self-registering  instrument  by  which  a  continuous  record  is 
made  of  the  changes  in  the  direction  of  the  needle,  we  shall  notice  a 
diurnal  variation  of  the  declination,  in  northern  latitudes,  substantially 
as  follows :  During  the  night  the  needle  will  be  comparatively  quiet ;  but 
at  dawn  of  day  the  north  end  will  move  toward  the  east,  and  will 
continue  this  decrease  of  declination  till  about  8  o'clock  A.  M.,  when  it 
will  commence  a  westerly  motion,  and  will  come  to  its  maximum  west 
declination  at  about  2  o'clock  p.  M.  It  will  then  return  toward  the  east 
until  some  hours  after  sunset,  when  it  will  again  remain  quiet  till  the  next 
dawn.  But  while  this  is  in  general  true,  it  must  be  taken  with  much 
allowance.  In  the  first  place,  it  must  not  be  understood  that  the  needle 
is  stationary  even  at  night,  for  it  seldom,  if  ever,  fails  to  show  more  or 


THE  USE  OF  THE  MAGNETIC  NEEDLE  IN  SURVEYING. 

less  change  every  hour  of  the  twenty-four ;  but,  ordinarily,  the  change  is 
much  less  during  the  night  than  in  the  day-time.  The  extent  of  this 
variation  is  not  the  same  in  all  places,  nor  on  different  days  in  the  same 
place.  It  is  greater  in  summer  than  in  winter,  and  on  clear  days  than  in 
cloudy  weather.  At  Hanover  it  is  about  15'  in  winter,  and  perhaps  20' 
in  summer.  The  morning  deviation  eastward  from  the  direction  during 
the  night  is  usually  about  one  third  of  the  whole  variation,  or  one  half  of 
the  westward  deviation  from  the  same  direction  at  2  o'clock  p.  M.  We 
give  herewith  a  few  curves  showing  the  diurnal  variation  at  Hanover,  in 
January,  1872,  from  which  a  better  idea  can  be  obtained  than  from  any 
verbal  explanation.  Of  these  curves  we  shall  see  that  no  two  are  pre 
cisely  alike;  and,  if  we  should  examine  the  curves  for  each  day  of  the 
year,  we  should  find  the  same  variety  that  is  observed  in  the  weather  of 
different  days.  In  these  diagrams,  each  curve  has  upon  it  the  date  at 
which  it  wras  observed.  The  vertical  divisions  indicate  minutes  of  arc, 
and  are  numbered  for  Jan.  I  on  the  left  hand,  for  Jan.  2  on  the  right,  and 
so  on,  alternating  for  each  day.  Thus,  wThile  the  zero  line  of  each  curve 
represents  the  same  direction  of  the  needle,  a  different  line  in  each  case 
is  used  for  zero,  to  prevent  confusion  by  the  curves  intersecting  and 
blending  together.  A  tendency  of  the  curve  upward  indicates  motion  of 
the  north  end  of  the  needle  eastward,  or  decrease  of  declination,  and 
downward  indicates  increase  of  declination.  To  determine,  therefore, 
the  relative  pointings  of  the  needle  at  the  same  time  on  any  two  of  these 
days,  compare  each  with  its  own  zero.  For  example,  at  2  o'clock  p.  M.,  on 
Jan.  i,  the  pointing  was  — 6'.  5  ;  Jan.  2,  it  was  — 6';  Jan.  3,  • — 2';  Jan.  5, 
— 2 '.4 ;  Jan.  6,  — 2 '.5,  &c.  January  9,  it  will  be  observed,  was  a  day  of  con 
siderable  disturbance,  and,  at  2  p.  M.,  the  pointing  was  +7'.3,  being  from 
10'  to  14'  farther  east  than  on  previous  days;  and  the  average  pointing 
on  that  day  and  for  several  succeeding  days  was  about  10'  or  12'  east 
ward  of  the  usual  direction  of  the  needle.  Of  this  we  shall  say  more  in 
speaking  of  magnetic  storms. 

4.  TJie  annual  variation  of  the  Declination.  Besides  the  changes  in 
declination  already  mentioned,  there  is  an  annual  variation  produced  by 
the  changing  seasons  of  the  year.  This  is  perhaps  so  small  as  to  be  of 
little  practical  importance  in  the  ordinary  use  of  the  needle,  but  it  should 
not  be  omitted  in  a  full  discussion  of  the  subject.  Observations  have

not  been  sufficiently  multiplied  to  enable  us  to  state  with  certainty  the 
extent  and  manner  of  this  variation  for  New  England.  Cassini  began 
daily  observations  in  Paris,  in  1783,  by  which,  in  1786,  he  was  able  to 
announce  the  discovery  of  this  annual  variation.  By  his  observations  it 
appeared  that  the  westerly  declination  increased  from  June  20  to  March 
20,  and  from  March  20  to  June  20,  decreased  by  about  one  third  of  the 
increase  from  June  to  March.  Subsequent  observations  in  other  places 
do  not  fully  confirm  the  results  obtained  by  Cassini.  It  is  more  probable 
that  there  are  two  periods  of  retrogression,  one  between  the  vernal 
equinox  and  summer  solstice,  and  the  other  between  the  autumnal  equi 
nox  and  winter  solstice.  This  seems  to  be  indicated  by  the  observations 
of  Gilpin,  about  the  beginning  of  the  present  century,  in  England.  But 
it  is  not  necessary  for  our  present  purpose  to  pursue  this  part  of  the 
subject  further,  as  this  variation  in  New  England  is  too  small  to  require 
notice  in  the  use  of  the  needle,  being  probably  less  than  one  minute. 

5.  Magnetic  Storms.  Those  irregular  and  occasional  disturbances  in 
terrestrial  magnetism  called  magnetic  storms,  are  generally  attended  by 
an  aurora,  and  no  doubt  are  one  effect  of  the  same  cause  which  produces 
the  aurora.  They  occur  by  day  as  well  as  by  night,  and  therefore  are 
not  always  accompanied  by  a  visible  aurora.  Their  duration  and  the 
amount  of  disturbance  they  produce  are  as  varied  as  the  features  of  our 
rain-storms.  During  a  magnetic  storm  the  needle  is  observed  to  be 
unsteady  and  tremulous,  changing  its  direction,  now  this  way  and  now 
that,  to  an  extent  dependent  on  the  magnitude  of  the  storm.  Slight 
disturbances  of  this  kind,  affecting  the  direction  of  the  needle  by  a  few 
minutes,  are  not  uncommon.  The  diurnal  curve  for  January  9,  1872, 
shows  such  a  disturbance.  This  disturbance  continued  through  the 
night,  beyond  the  limits  of  this  diagram ;  and,  as  before  stated,  for 
several  days  after,  the  average  pointing  of  the  needle  was  some  10' 
farther  east  than  usual.  There  were  also  many  other  days  of  unusual 
disturbance  during  this  month ;  and  on  the  4th  of  the  following  month  a 
most  remarkable  storm  was  observed  by  the  writer  and  his  assistants  at 
the  Dartmouth  College  observatory.  The  day  was  cold  and  windy,  the 
weather  clearing  after  a  heavy  fall  of  snow.  In  the  evening  appeared 
that  most  remarkable  aurora,  covering  the  whole  heavens  south  as  well 
as  north,  which  many  will  remember,  and  which  was  seen  in  Europe  as

well  as  on  this  continent.  The  assistant  in  charge  of  the  magnetometer 
noticed  early  in  the  forenoon  of  this  day  an  unusual  disturbance  of  the 
needle,  and  was  thoughtful  enough  to  make  his  observations  every  few 
minutes,  and  sometimes,  at  the  height  of  the  storm,  every  half  minute, 
instead  of  the  usual  hourly  observations.  The  annexed  diagram  shows 
this  storm  between  nh  53™  A.  M.,  and  I21'  53'"  p.  M.  The  vertical  lines 
denote  minutes  of  mean  solar  time,  and  the  horizontal  spaces  are  each  5' 
of  arc.  To  compare  the  disturbance  during  this  hour  with  the  usual 
diurnal  variation,  as  represented  on  page  14,  it  must  be  noted  that  if  the 
former  were  represented  on  the  same  scale  as  the  latter,  it  would  appear 
to  be  nearly  twenty-five  times  greater  than  here  shown.  The  figures 
at  the  right  and  left  margin  are  reckoned  from  a  zero  below  the  limits  of 
this  diagram,  and  which  was  the  normal  pointing  when  the  needle  was 
undisturbed.  It  will  be  noticed  that,  at  iih  53™  A.  M.,  the  north  end  of 
the  needle  had  moved  eastward  of  its  normal  position  2°  05'.  This 
movement  commenced  about  10  o'clock,  and  went  on  with  some  irregu 
larity  up  to  the  time  when  our  diagram  commences.  From  this  time  the 
eastward  movement  was  more  rapid,  particularly  after  1 2  M., — from  1 2!l  to 
1 2h  01 m,  increasing  i°  25'.  At  i2hO7mthe  greatest  eastward  deviation 
was  reached,  which  was  5°  25'  east  of  the  normal  pointing.  After  this 
the  westward  motion  was  quite  rapid,  with  considerable  disturbance,  how 
ever,  and  with  two  very  marked  and  sudden  fluctuations  to  the  east,  in 
which  it  reached,  within  30',  its  maximum  deviation.  The  most  violent 
'disturbances  of  this  storm  occurred  within  the  hour  here  represented. 
After  I211  53m  p.  M.,  the  needle  became  gradually  more  quiet,  and  by  3 
p.  M.  had  returned  nearly  or  quite  to  its  usual  position.  In  the  evening, 
during  the  remarkable  display  of  aurora,  though  somewhat  disturbed, 
the  fluctuations  were  by  no  means  so  great  as  during  the  day.  We  can- 
"not,  of  course,  positively  affirm  that  this  aurora  was  not  present  during 
the  day,  but  it  seems  more  than  probable  that  the  needle  is  more  affected 
by  the  approach  than  by  the  presence  of  an  aurora,  particularly  of  one 
like  this,  extending  over  the  whole  heavens.  It  would  of  course  be 
impossible  to  use  the  needle  in  surveying  at  such  a  time,  as  by  the  sudden 
changes  in  the  direction  of  the  magnetic  force  it  would  be  kept  constantly 
oscillating.  It  must  not  be  understood  that  during  this  hour  the  nee 
dle  moved  steadily  back  and  forth  as  shown  in  the  diagram,  but  it  was

1 62  PHYSICAL    GEOGRAPHY. 

swinging  sometimes  4°  or  5°,  and  the  pointings  here  indicated  are  the 
means  of  the  two  extremes  of  oscillation. 

The  Construction  and  Use  of  the  Magnetic  Needle.  From  the  foregoing 
it  will  be  easy  to  deduce  the  value  of  the  magnetic  needle  in  determining 
directions,  and  the  precautions  necessary  in  the  use  of  it.  In  the  first 
place,  the  greatest  care  must  be  exercised  in  the  construction  of  the 
needle  and  its  accompaniments.  The  most  important  points  of  construc 
tion  are  these : 

1.  The  magnetic  axis  of  tlie  needle  should  coincide  with  a  line  joining 
its  extreme  points, — otherwise  it  will  fail  to  indicate  the  true  magnetic 
meridian.     This  would  be  of  little  consequence  in  using  a  single  needle, 
but,  in  comparing  the  work  of  different  needles,  as  must  frequently  be 
done,  it  becomes  important.     The  magnetic  axis  of  a  needle  may  be 
determined  by  suspending  it  in  a  stirrup  by  an  untwisted  fibre  of  silk — 
first  one  side  up  and  then  the  other — and  observing  the  pointings  in  each 
position.     This  test  should  be  applied  by  the  maker  of  the  needle,  and 
the  magnetic  axis  be  made  to  coincide  with  the  axis  of  the  needle. 

2.  The  suspension  of  the  needle  should  be  such  as  to  reduce  friction  to  a 
minimum.     Since  that  component  of  the  magnetic  force,  which  tends  to 
bring  the  needle  to  the  magnetic  meridian,  diminishes  as  the  sine  of  the 
angle  the  needle  makes  with  that  meridian,  it  will  require  but  little  friction 
to  cause  it  to  stop  so  far  out  of  the  meridian  as  to  introduce  an  apprecia 
ble  error  into  the  results.     The  best  compass  needles  are  poised  upon  a 
fine  needle  point,  in  an  agate  or  other  jewelled  socket;  but  with  such  a 
needle  no  less  care  is  requisite  to  keep  it  than  to  make  it  right.     The 
more  delicate  the  point,  the  more  liable  it  is  to  injury,  and  it  can  be  kept 
in  proper  condition  only  by  raising  the  needle  from  it  when  the  compass  is 
moved,  and  letting  it  down  carefully  when  to  be  used.     The  arrangement 
for  raising  the  needle  should  be  a  screw  and  not  a  cam,  as  the  latter  is  liable 
to  work  loose  in  transportation,  and  allow  the  needle  to  fall  upon  the  point. 

3.  The  compass-box  and  tripod  should  be  free  from  everything-  magnetic. 
Not  only  should  no  iron  be  used  in  their  construction,  but  the  brass  for 
the  compass-box  and  tripod-head  should  be  tested  to  determine  whether 
it  has  any  power  of  attracting  the  needle.     In  two  instances  known  to 
the  writer,  the  brass  of  a  compass-box  has  become  so  magnetic  as  to 
destroy  the  value  of  the  instrument.    It  is  easy  to  determine  whether  such 


THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  163 

Is  the  case,  by  directing  the  sights  to  various  objects  in  different  direc 
tions,  reversing  on  each,  and  noting  whether  the  needle  gives  a  different 
reading  by  any  of  the  reversals.  If  the  reading  is  not  changed  by  re 
versing  in  any  of  the  positions,  the  box  may  be  considered  free  from 
magnetic  power. 

4.  The  pivot  should  be  exactly  in  the  centre  of  the  graduated  circle,  that 
the  two  ends  of  the  needle  may  give  the  same  reading.     It  is  true  this 
error  may  be  eliminated  by  reading  both  ends,  and  taking  the  mean ;  but 
It  is  better  to  have  no  error  to  eliminate.     If,  however,  the  two  ends  do 
not  read  alike,  the  mean  reading  should  be  used. 

5.  In  using  tJie  compass,  proximity  to  all  magnetic  substances,  both 
natural  and  artificial,  must  be  avoided.     Masses  of   iron,  like  gas-  or 
water-pipes,  water-conductors,  and  lightning-rods,  are  a  source  of  disturb 
ance  not  easily  avoided  in  cities  ;  and  the  water-conductors  and  lightning- 
rods  being  placed  vertically  are  more  disturbing  than  larger  masses  lying 
horizontally.     The  reason  of  this  is  that,  having  their  longer  axis  more 
nearly  in  the  direction  of  the  force  of  terrestrial  magnetism,  they  become 
magnetic  by  induction,  and  act  not  merely  as  so  much  iron,  but  as  mag 
nets.     They  must  therefore  be  given  a  wide  berth  by  the  surveyor  with 
the  magnetic  needle.     In  making  observations  with  the  magnetometer,  it 
is  thought  necessary  to  remove  from  such  objects  to  a  distance  at  least 
equal  to  twice  their  height ;  but  it  is  probable  that  no  perceptible  influ 
ence  upon  an  ordinary  needle  would  be  observed  at  half  that  distance. 

Besides  these  larger  masses  of  iron,  the  surveyor  sometimes  carries  upon 
his  person  the  cause  of  much  error.  Ordinary  knives,  if  not  brought 
nearer  to  the  needle  than  two  or  three  feet,  will  have  no  appreciable 
effect,  but  magnetized  knives  should  be  kept  at  a  greater  distance;  and 
the  chain-men  should  not  be  allowed  to  bring  the  chain  within  less  than 
twenty  feet  of  the  instrument.  There  is  another  source  of  disturbance, 
carried  by  the  surveyor  himself,  which  frequently  he  does  not  suspect.  It 
is  the  common  buttons,  with  an  iron  body,  used  upon  coats.  In  reading 
the  bearing,  these  are  likely  to  be  brought  near  to  the  needle,  and  to  pro 
duce  considerable  deviation.  Such  buttons  ought  not  to  be  worn  in 
working  with  a  compass. 

Still  more  difficult  is  it  to  avoid  local  attraction  by  magnetic  rocks, 
which  are  more  common  than  is  generally  supposed.  Indeed,  so  common 


164  PHYSICAL    GEOGRAPHY. 

is  this  source  of  error,  that  in  every  case  the  bearing  of  a  line  should  be 
taken  at  two  places  at  least,  and  these  should  be  as  far  apart  as  possible. 
If  the  two  bearings  agree,  it  may  be  safely  concluded  that  they  are  cor 
rect,  and  not  affected  by  local  attraction.  Yet  it  must  not  be  forgotten 
that  it  is  possible,  though  highly  improbable,  that  two  bearings  thus  taken 
should  be  equally  affected.  If  the  line  is  very  short,  or  if  no  two  points 
on  it  can  be  found  at  which  the  bearings  agree,  a  point  may  be  taken  out 
of  the  line  in  any  direction,  and  at  a  suitable  distance ;  and,  if  the  direct 
and  reverse  bearings  from  it  to  any  point  of  the  line  be  found  to  agree, 
those  points  may  be  considered  free  from  local  attraction.  In  some 
places,  as  in  the  vicinity  of  iron  mines,  it  will  be  found  impracticable  to 
use  the  needle  at  all  for  the  determination  of  bearings ;  but  even  in  this 
case,  the  figure  and  area  of  a  field  may  be  found  by  so  placing  the  com 
pass  at  each  angle  as  to  take  the  bearings  of  the  two  adjacent  sides  from 
the  same  point.  This  will  give  the  angle  between  these  sides  without 
error  from  local  attraction. 

The  most  difficult  problem  ever  presented  to  the  surveyor  is  that  which 
asks  him  to  retrace  a  lost  line,  with  but  one  point  known,  and  the  bearing 
from  some  old  deed.  To  add  to  his  perplexity,  the  parties  in  interest  are 
usually  too  much  excited  by  the  apprehension  of  being  robbed  of  a  square 
rod  of  rocky  pasture,  or  of  swamp  rich  in  mud  and  brakes,  to  be  able  to 
give  correctly  such  facts  as  might  be  serviceable  in  the  solution  of  the 
problem.  In  such  case,  if  the  parties  cannot  be  induced  to  agree  upon  a 
second  bound  and  thus  determine  the  line,  there  is  no  way  but  to  "mu 
by  the  needle"  after  making  due  allowance  for  change  in  declination  since 
the  previous  survey.  Running  in  this  way  may  lead  to  the  discovery  of 
some  old  landmark,  nearly  obliterated,  and  thus  settle  the  dispute  ;  but  if 
not,  though  the  error  in  the  bearing  is  likely  to  be  15'  to  30',  it  is  better 
than  a  lawsuit ;  and  if,  in  such  case,  the  parties  in  their  ignorance  believe 
that  to  be  "true  as  the  needle  to  the  pole"  is  to  be  true  enough  it  is 
certainly  an  occasion  where  "  't  is  folly  to  be  wise." 

Determination  of  a  true  meridian.  That  the  surveyor  may  be  able  to 
test  his  compass  by  some  well  established  meridian,  it  would  be  an 
economical  measure  if  the  state  should  locate  and  permanently  mark  a 
true  meridian  in  one  or  more  of  the  principal  towns  of  each  county, 
and  then  require  by  law  all  surveyors  to  record  the  declination  with  the 


THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  165 

plan  or  report  of  every  survey,  stating  at  what  time  and  by  which  of 
these  meridians  the  declination  was  taken. 

In  the  absence  of  such  meridians  located  at  the  public  expense,  the 
surveyor  may,  with  little  trouble,  determine  one  for  himself.  The  remain 
der  of  this  paper  will  be  devoted  to  an  explanation  of  some  of  the 
methods  by  which  the  astronomical  meridian  of  a  place  may  be  found. 

I.  By  observations  upon  the  pole  star  (Polaris).  This  star  has  now 
(Jan.  i,  1874)  a  polar  distance  of  i°  21'  45",  with  an  annual  diminution 
of  19",  and  it  may  be  observed  either  at  its  culmination  or  elongation,  or 
at  any  other  known  time.  The  time  selected  for  the  observation  must 
depend  on  the  circumstances  of  the  observer.  If  he  has  not  the  means 
of  determining  his  local  time  within  fifteen  seconds,  he  must  take  the  star 
at  its  elongation  ;  but  if  he  can  know  the  time,  he  may  observe  whenever 
it  is  most  convenient  to  himself.  The  culminations  offer  the  advantage 
of  giving  the  meridian  at  once,  without  computation  or  correction  for 
azimuth ;  but  neither  at  the  culmination  nor  at  the  elongation  can  double 
observations  be  taken  to  eliminate  any  error  in  the  adjustment  of  instru 
ments,  and  if  the  single  observation  be  missed  at  the  moment,  it  cannot 
be  repeated  till  the  next  night.  It  may  therefore  be  more  convenient  to  ob 
serve  without  reference  to  these  ;  but  in  that  case  the  local  time  must  be 
known,  the  azimuth  of  the  star  computed,  and  the  proper  correction  applied. 

These  observations  may  be  made  with  a  theodolite  or  transit,  or,  for 
want  of  these,  we  may  use  simply  a  plumb-line,  with  a  compass-sight,  or 
anything  with  a  small  hole  in  it  to  look  through.  Any  heavy  body  sus 
pended  by  a  string  will  serve  for  a  plumb,  and  it  may  be  suspended  in 
water  to  give  it  greater  stability.  It  should  not,  however,  even  then  be 
used  in  any  considerable  wind,  as  this  will  cause  it  to  deviate  from  a 
vertical.  South  of  the  plumb-line,  and  at  a  convenient  distance,  fix  a 
board  firmly  in  a  horizontal  position,  upon  which  a  small  piece  of  board, 
with  a  compass-sight  affixed,  may  be  moved  east  and  west"  Bring  this  in 
line  with  the  star  and  plumb-line,  and  follow  the  star  until  the  time  of 
culmination,  then  fasten  the  compass-sight,  and  the  meridian  is  secured. 
Or,  if  the  time  of  an  elongation  be  selected  for  the  observation,  bring  the 
compass-sight  into  line  a  little  before  the  time,  and  follow  the  star  till  it 
begins  its  return.  This  line,  with  the  proper  correction  for  azimuth,  will 
be  the  true  meridian.  So,  also,  if  the  observation  be  made  at  any  time 


1 66  PHYSICAL    GEOGRAPHY. 

(the    time   being   noted),  and   the   proper   correction   applied,  the   true 
meridian  will  be  determined. 

If  a  transit  or  theodolite  is  used,  it  must  be  carefully  adjusted,  or  the 
results  will  be  less  reliable  than  by  the  simple  plumb-line,  as  above.  The 
adjustments  liable  to  affect  the  work  are  the  collimation,  and  the  height 
of  Y's  or  horizontality  of  the  axis  of  the  telescope.  By  making  two 
observations, — one  with  the  telescope  reversed,  and  using  the  mean 
result, — any  error  which  would  otherwise  occur  by  defect  in  these  adjust 
ments  is  eliminated ;  but  in  this  case  both  observations  cannot  be  taken  at 
the  moment  of  culmination :  hence,  for  one,  at  least,  the  azimuth  must  be 
computed.  If  neither  is  taken  at  the  culmination,  separate  azimuths  must 
be  computed  for  each. 

Unless  an  instrument  with  a  perforated  axis  for  illumination  of  spider 
lines  is  used,  some  easily  managed  means  must  be  contrived  for  this 
illumination.  If  a  steady  light  cannot  be  thrown  upon  the  lines  in  such 
way  that  it  may  be  increased  or  diminished  at  pleasure,  it  is  not  easy  to 
see  both  the  star  and  lines  with  that  distinctness  necessary  to  a  good 
observation.  With  the  perforated  axis  there  is  little  difficulty  in  securing 
the  right  amount  of  light ;  but  without  this,  the  light  must  be  thrown 
into  the  object  end  of  the  telescope.  This  can  be  done  successfully  by 
using  a  stand  to  carry  a  bull's-eye  lantern,  and  a  vertical  piece  of  board 
covered  with  white  paper  to  serve  as  a  reflector,  the  diffused,  reflected 
light  being  much  better  than  the  direct  rays  of  the  lantern ;  or,  a  ring  of 
thin  white  paper,  of  suitable  size  to  cover  the  outer  edge  of  the  object  glass, 
leaving  the  centre  open,  may  be  made  to  adhere  to  the  glass  by  simple 
wetting,  which  will  serve  to  reflect  and  diffuse  the  light  thrown  upon  it. 

To  mark  the  meridian  after  the  observation,  a  piece  of  board  with  a 
small  hole,  behind  which  a  light  is  placed,  will  serve  as  a  temporary 
arrangement.  This  need  not  be  placed  precisely  in  line  of  the  meridian, 
but  being  fastened,  before  observing,  at  some  point  near  this  line,  the 
angle  between  it  and  the  star  may  be  taken,  and  the  work  of  fixing  and 
permanently  marking  the  meridian  be  deferred  to  any  convenient  time. 
When  the  final  marking  is  done,  it  should  be  such  that  neither  frost  nor 
any  other  natural  causes  will  disturb  it. 

2.  A  meridian  may  be  established  by  observations  upon  tJie  sun ;  but, 
while  they  offer  the  advantage  of  the  day-time  for  doing  the  work,  they 


THE    USE    OF    THE    MAGNETIC    NEEDLE    IN    SURVEYING.  l6/ 

are  not,  on  the  whole,  so  convenient  as  the  use  of  the  pole  star.  One 
objection  to  them  is,  that,  as  the  centre  ot  so  large  a  body  cannot  be 
accurately  observed,  it  is  necessary  to  observe  the  limb  or  edge ;  and  thus 
a  computation  is  necessary  to  reduce  to  the  centre,  or  a  second  observa 
tion  must  be  made  on  the  opposite  limb  to  eliminate  the  error.  Hence, 
in  no  way  can  a  meridian  be  directly  found  by  solar  observations  without 
computation  and  correction  for  azimuth,  except  by  the  rough  and  unreli 
able  method  of  guessing  at  the  sun's  centre  when  on  the  meridian.  These 
observations  require,  also,  the  use  of  a  telescope  with  a  darkened  glass, 
which  is  not  always  at  hand.  The  most  convenient  way  of  locating  a 
meridian  by  the  sun  is  to  take  its  altitude  in  the  morning  or  evening, 
when  the  altitude  is  rapidly  changing,  and  measuring  the  angle  between 
it  and  some  fixed  mark.  The  azimuth  of  the  sun  may  be  computed  by 
data  found  in  the  nautical  almanac,  whence  the  azimuth  of  the  mark 
becomes  known,  and  the  meridian  is  determined.  By  this  method, 
double  observations  must  be  made  to  eliminate  the  error  of  taking  the 
limb  instead  of  the  centre,  and,  also,  by  reversing  the  telescope,  to 
eliminate  error  in  collimation  and  height  of  Y's,  and  in  the  position  of 
the  zero  of  the  vertical  circle.  In  one  observation,  bring  the  sun  into  one 
angle  of  the  spider  lines  and  tangent  to  each ;  then  read  the  horizontal 
and  vertical  circles ;  point  to  the  mark,  and  read  the  horizontal  circle ; 
reverse  the  telescope,  and  take  the  sun  in  the  same  manner  as  before, 
but  in  the  opposite  angle, — that  is,  upon  the  opposite  side  of  both  lines ; 
read  the  circles  again,  and  observe  the  mark  as  before.  It  would  make 
the  work  still  more  sure  to  take  a  second  set  in  the  other  angles  of  the 
lines,  but  this  is  not  essential.  The  mean  azimuth  of  the  mark,  as  obtained 
by  the  different  observations,  will  be  its  true  angle  with  the  meridian. 

If  the  local  time  is  known  and  noted  with  each  observation,  the  azimuth 
of  the  sun  may  be  computed  without  observing  its  altitude;  but  it  is 
easier  to  observe  the  altitude  than  to  find  the  time.  To  take  the  sun, 
when  on  the  meridian,  will  also  require  the  time  with  a  correction  for  the 
difference  between  apparent  and  mean  time.  Much  better  than  these 
solar  methods,  will  be  found  the  following : 

3.  By  observations  upon  any  one  of  tJic  stars.  Select  some  bright  star, 
as  Sirius  or  the  planet  Jupiter,  that,  if  possible,  the  spider  lines  may  be 
seen  without  artificial  illumination.  If  this  can  be  done,  it  will  save  the 


1  68  PHYSICAL    GEOGRAPHY. 

trouble  of  adjusting  a  light  for  this  purpose.  With  a  theodolite  having 
a  vertical  circle,  which  has  been  previously  adjusted  with  care  and  firmly 
set  (as  in  all  these  observations  the  instrument  should  be),  take  the  star 
at  least  three  hours  before  its  culmination,  recording  its  altitude  and  the 
angle  it  makes  with  the  mark  ;  reverse  the  telescope,  and  observe  in  the 
same  way  again.  Note,  also,  the  time  of  each  observation  with  sufficient 
accuracy  to  be  ready  for  the  star  at  the  same  altitude  after  culmination. 
Before  the  star  descends  to  this  altitude,  set  the  vertical  circle  to  that 
altitude,  with  the  telescope  in  the  same  position  (direct  or  reverse)  as 
when  the  observation  at  the  same  altitude  was  made  before  culmination, 
and,  as  soon  as  it  can  be  done,  bring  the  star  into  the  field  by  turning 
only  the  horizontal  circle  ;  put  the  vertical  line  upon  the  star,  and  follow 
it  till  it  comes  to  the  intersection;  read  both  circles,  and  observe  the 
mark;  reverse  the  telescope,  set  to  the  other  altitude,  and  observe  the 
star,  and  mark  again  in  the  same  manner.  Find  the  mean  angle  between 
the  star  and  mark  by  the  first  set  of  observations  taken  before  culmina 
tion,  and,  also,  by  those  taken  after  ;  and  the  half  difference  of  these  two 
angles  will  be  the  angle  between  the  mark  and  meridian.  By  this  method 
of  equal  altitudes,  all  trouble  of  finding  the  exact  local  time,  and  of 
computations,  is  avoided. 

It  remains  only  to  give  the  formulae  for  computing  the  azimuth  of  the 
pole  star,  —  i.  When  taken  at  its  elongation  ;  and,  2.  When  taken  at  any 
other  time. 

1.  Let  /  —  the  polar  distance  of  the  star. 

/  =  the  latitude  of  the  observer. 
z  =  the  required  azimuth. 
Then  we  have 

sin/> 

sins  =  —  f- 
sin/ 

when  taken  at  the  elongation. 

2.  Using  the  same  notation  as  above,  with  the  addition  of  t  =  the 
time  since  the  last  culmination  reduced  to  degrees,  &c.,  of  arc,  we  have 

cos  (/  4-  k]  cot  / 
cotz  =  -  —  r-    —, 

sin  k 

in  which 


=  tan/  cos/, 
when  the  observation  is  not  at  the  elonation. 


NOTE.  Inasmuch  as  this  chapter  explains  satisfactorily  the  proper  way  of  using  the  magnetic  needle,  I  take 
occasion  here  to  say  that  all  the  courses  mentioned  subsequently  in  this  report  may  be  understood  as  referring 
to  the  true  meridian.  They  were  taken  with  pocket  compasses  originally,  and  have  been  corrected  according 
to  the  principles  stated  so  lucidly  by  Prof.  Quimby.  C.  H.  H. 


CHAPTER  VII. 

TOPOGRAPHY. 

iHE  general  shape  of  the  territory  of  New  Hampshire  is  that  of  a 
scalene,  almost  a  right-angled  triangle, — having  the  perpendicular 
one  hundred  and  eighty,  and  the  base  seventy-five  miles  long.  From  the 
crown  monument,  at  the  extreme  north  point,  to  the  south-east  corner  of 
Pelham,  at  the  most  southern  extension,  the  distance  is  one  hundred  and 
eighty  miles, — the  length  of  the  perpendicular.  The  longest  distance 
that  can  be  measured  in  the  state  is  from  the  crown  monument  to  the 
south-west  corner,  a  distance  of  one  hundred  and  ninety  miles,  and  this 
line  would  be  the  hypothenuse  of  the  triangle.  The  greatest  width  of 
the  state  is  from  Chesterfield  to  the  outer  island  of  the  Isles  of  Shoals,  a 
distance  of  one  hundred  miles.  To  the  outermost  projection  of  Rye 
from  Chesterfield,  the  distance  is  seven  miles  less.  At  Colebrook,  the 
width  of  the  state  is  only  twenty  miles. 

New  Hampshire  is  bounded  north  by  the  province  of  Quebec,  east  by 
the  state  of  Maine,  south-east  by  the  Atlantic  ocean  and  Essex  county, 
Mass.,  south  by  the  state  of  Massachusetts,  west  and  north-west  chiefly 
by  the  state  of  Vermont,  and  partially  by  Quebec.  It  lies  between 
70°  37'  and  72°  37'  longitude  west  from  Greenwich,  and  between  42°  40' 
and  45°  18'  23 "  north  latitude. 

The  books  usually  give  the  area  of  the  state  as  9,280  square  miles. 
Mr.  Warren  Upham  carefully  measured  the  area  of  the  state  upon  J.  R. 
VOL.  i.  24 


PHYSICAL    GEOGRAPHY. 

Dodge's  map,  published  in  1854,  and  finds  it  to  be  very  nearly  8,8 1 8 
square  miles,  although  the  explanations  in  the  margin  state  the  figure  to 
be  9,280.  The  scale  given  on  this  map  is  evidently  incorrect,  perhaps  on 
account  of  the  usual  want  of  correspondence  between  an  original  draft  and 
the  printed  sheet.  Hence  I  have  had  the  area  carefully  measured  upon 
the  original  draft  of  our  new  map,  or  the  one  which  appears  in  the 
accompanying  atlas,  and  find  it  to  be  9,336  square  miles.* 

Our  territory  possesses  a  mountainous  character,  much  more  so  than 
the  average  among  the  states  along  the  Atlantic  slope  of  the  continent. 
It  is  situated  about  a  third  of  the  way  from  the  north-eastern  end  of  the 
Atlantic  system  to  the  south-western  extremity  of  the  chain.  Viewed 
as  a  whole,  there  are  two  culminating  points  in  this  system.  The  land 
rises  gradually  from  the  ocean  level  in  the  Gulf  St.  Lawrence  till  the 
apex  of  the  White  Mountains  is  reached.  Then  it  falls  to  the  Hudson 
river,  reaching  the  ocean  level  along  that  valley.  From  this  line  it 
ascends  to  the  mountains  in  western  North  Carolina,  whence  the  land 
descends  to  the  Gulf  of  Mexico. 

More  particularly,  there  is  a  mountainous  ridge  following  the  eastern 
rim  of  the  Connecticut  river  basin  entirely  through  the  state.  On  the 
east  the  country  is  low,  scarcely  rising  above  five  hundred  feet  for  three 
fourths  of  the  area  outside  of  the  foot  hills  of  the  White  Mountains. 
These  mountains  occupy  nearly  all  the  space  east  of  the  western  ridge  to 
the  Maine  line,  for  a  distance  north  and  south  of  about  thirty-three  miles. 
This  district  is  mostly  wooded,  very  mountainous,  and  scarcely  inhabited. 
Deep  transverse  valleys  divide  the  White  Mountains  proper  from  a  simi 
lar  triangular  area  between  the  Androscoggin  and  Connecticut  rivers. 
There  is  a  third  mountainous  district  half  way  through  Coos  county,  and 
the  fourth  and  last  along  the  extreme  northern  boundary.  On  the  other 


*  The  calculations  were  made  by  Mr.  T.  B.  Mann,  of  Boston.  There  are  two  or  three  points  in  connection  with 
the  calculation  that  need  to  be  mentioned.  The  proper  west  line  of  New  Hampshire  is  the  west  side  of  Con 
necticut  river.  At  the  mouth  of  the  Passumpsic,  where  the  Connecticut  has  three  channels,  the  calculation  has 
omitted  the  narrow  channel,  and  a  large  island  next  to  the  Vermont  side.  In  Portsmouth  harbor,  no  islands 
outside  of  Newcastle  are  included.  The  centre  of  Salmon  Falls  river  and  the  ponds  between  Wakeficld  and 
Portsmouth  harbor  was  regarded  as  the  east  line  of  the  state.  At  Seabrook  and  Rye,  the  measurement  includes 
the  bays  at  the  mouths  of  rivers,  running  from  headland  to  headland.  The  Isles  of  Shoals  are  not  included, 
which  do  not  seem  to  cover  more  than  one  square  mile.  If  to  this  figure  we  add  a  square  mile  for  the  neglected 
channel  in  Monroe,  and  54  miles  for  the  belt  of  three  miles  of  ocean  over  which  our  authorities  exercise  jurisdic 
tion,  the  total  area  may  be  stated  at  9,392  square  miles.

side  of  the  Connecticut  there  is  a  similar  elevated  country,  constituting 
the  sparsely  settled  district  of  Essex  county,  Vt.  In  mineral  features 
this  is  like  the  White  Mountains,  and  should  properly  belong  to  New 
Hampshire,  if  the  boundary  line  between  us  and  Vermont  were  at  all  sym 
metrical.  As  it  is  topographically  connected  with  our  state,  I  shall  take 
occasion  to  refer  to  it  often,  and  to  describe  it,  so  far  as  may  be  practica 
ble,  considering  its  extra-limital  position,  and  the  scantiness  of  our 
information  concerning  it.  Our  survey  has  done  something  towards  its 
exploration,  though  by  no  means  so  fully  as  is  desirable. 

The  area  of  our  field  of  exploration  may  be  divided  into  six  districts, 
each  of  which  will  be  described  in  detail.  They  are  the  topographical 
divisions  that  suggest  themselves  most  naturally. 

1.  Hydrographic  basin  of  the  Connecticut  river,  leaving  the  main  valley 
at  Barnct,  and  continuing  up  the  Passumpsic  to  its  source. 

2.  Hilly  district  of  the  principal  portions  of  Coos  county,  N.  H.,  and 
Essex  county,  Vt. 

3.  White  Mountain  area. 

4.  Winnipiscogce  Lake  basin. 

5.  Merrimack  River  basin,  wedging  into  the  White  Mountain  area, 

6.  The  Atlantic  slope  in  Straff ord  and  RockingJiam  counties. 

These  districts  present  themselves  forcibly  to  the  eye  upon  the  accom 
panying  map. 

Before  describing  these  topographical  areas,  it  will  be  well  to  under 
stand  what  are  the  artificial  boundaries  of  New  Hampshire. 

THE  NORTHERN  BOUNDARY. 

The  northern  boundary  of  the  state  has  been  more  carefully  measured 
than  any  other,  having  been  surveyed  under  orders  from  the  United 
States  government,  for  the  purpose  of  marking  the  line  of  division 
between  New  Hampshire  and  Canada,  in  accordance  with  the  treaty  of 
Washington  bearing  date  of  August  9,  1842.  It  is  needless  here  to 
state  the  particulars  of  the  controversy  which  led  the  commissioners  to 
fix  upon  the  present  as  the  proper  boundary  line.  The  two  countries 
were  much  excited  previous  to  the  decision,  so  much  so  as  to  talk  of 
settling  the  dispute  by  fighting.  An  elegant  series  of  maps,  upon  the 
scale  of  one  mile  to  two  inches,  of  the  country  from  the  head  of  the 


PHYSICAL    GEOGRAPHY. 

St.  Croix  river  in  Maine  to  St.  Regis  on  the  St.  Lawrence  river,  may  be 
found  in  the  state  library  at  Concord,  which  was  prepared  from  very 
elaborate  surveys  after  instructions  from  Major  J.  D.  Graham,  of  the 
United  States  topographical  engineers,  principal  astronomer,  who  acted 
under  the  direction  of  congress.  Two  stations  along  the  New  Hamp 
shire  boundary  were  determined  astronomically  by  Major  Graham.  One 
of  these  is  situated  at  the  extreme  east  point  of  Vermont,  on  the  west 
side  of  Hall's  stream,  having1  the  latitude  of  45°  o'  17"  .58,  and  the 
longitude  west  from  Greenwich  of  71°  30'  34"  .5.  The  other  is  about 
half  a  mile  N.  10°  W.  from  Lake  Sophy,  or  Third  Connecticut  lake, 
having  the  latitude  of  45°  14'  58"  .06,  and  the  longitude  west  of 
Greenwich  of  71°  12'  57".  Distances  and  bearings  were  measured  care 
fully  by  chaining  and  triangulation.  The  trigonometrical  work  seems  to 
have  been  performed  under  the  guidance  of  different  engineers, — all  east 
of  Mt.  Prospect,  an  azimuth  station  about  half  a  mile  north-west  from 
the  small  Fourth  lake,  having  been  under  the  direction  of  Lieuts. 
Emory  and  Raynolds,  of  the  U.  S.  topographical  engineers,  while  that 
on  the  west  was  surveyed  by  A.  W.  and  S.  Longfellow,  civil  engineers. 
In  brief,  the  line  may  be  described  as  following  the  water-shed  between 
the  St.  Francis  and  Connecticut  rivers,  from  a  point  at  the  junction  of 
Maine,  New  Hampshire,  and  Quebec  province,  to  the  head  of  the  main 
Hall's  stream ;  thence  down  Hall's  stream  to  the  first  named  astronomi 
cal  station  of  Major  Graham.  It  is  hence  often  styled  the  "highland 
boundary." 

More  particularly,  the  boundary  may  be  thus  described  :  The  point  to 
which  the  three  territories  converge  is  known  as  "Crown  monument,"  or 
No.  474,  from  the  first  at  the  head  of  the  St.  Croix  river,  and  appears  to 
be  in  latitude  45°  18'  23"  .33  ;  longitude  71°  5'  40"  .5.  This  is  on  high 
land,  and  the  country  descends  to  the  next  post,  or  No.  475.  Monuments 
are  located  at  most  of  the  prominent  elevations  and  depressions,  as  the 
line  is  traced  westward.  Monuments  474  to  477  lie  along  the  head  waters 
of  the  Magalloway  (Margalloway,  as  spelled  by  the  commissioners  and 
Carrigain's  map).  No.  478  seems  to  be  situated  upon  rising  ground  not 
specially  connected  with  either  stream  ;  but  from  No.  478  to  No.  484,  we 
travel  along  the  little  streams  discharging  into  the  valley  of  Lake  Sophy. 
The  whole  of  the  Perry  stream  basin  lies  between  Nos.  484  and  485, 


TOPOGRAPHY.  1/3 

which  is  not  a  great  distance.  Nos.  483  and  484  lie  close  together,  and  are 
exactly  north  of  the  astronomical  station  near  Lake  Sophy.  The  country 
sloping  towards  Indian  stream  extends  from  monument  No.  485  to  No. 
500.  No.  489  is  near  the  point  of  a  curious  northerly  projection  into 
Quebec.  Nos.  501  to  506  are  on  the  slope  of  Hall's  stream.  No.  506  is 
exactly  on  the  head  of  the  main  Hall's  stream,  and  is  flanked  closely  by 
Nos.  505  and  507.  Nos.  508  to  517  lie  at  intervals  along  Hall's  stream 
to  the  east  end  of  the  north  line  of  Vermont.  The  total  length  of  the 
north  boundary  line  is  no  miles,  but  a  direct  course  between  the 
extreme  points  is  32.7  miles.  The  monuments  are  of  iron,  having  on 
them  the  names  of  the  U.  S.  and  H.  B.  M.  commissioners.  The  line 
itself  was  carefully  bushed  out  by  the  surveyors  as  wide  as  an  ordinary 
highway,  and  the  trees  have  not  yet  grown  up  again, — so  that  the  course 
of  the  boundary  is  still  conspicuously  marked. 

The  topographical  features  are  carefully  laid  down  along  the  whole  line. 
That  west  of  Hall's  stream,  in  Vermont,  appears  to  have  been  projected 
by  new  surveys  in  1851,  by  Lieut.  Thorn,  U.  S.  Engineers.  Monument 
No.  522  lies  just  west  of  Leach  Branch,  in  Canaan,  Vt.  Farther  west, 
Barnston  Pinnacle,  a  very  conspicuous  granitic  ledge,  is  said  to  rise  about 
600  feet  above  the  lake  at  its  base.  The  earlier  surveys  seem  to  have 
been  made  in  1845.  The  line  is  copied  as  accurately  as  possible  upon 
our  largest  map.  Mr.  Huntington  has  written  something  concerning  the 
altitudes  of  this  highland  boundary,  in  his  sketch  of  the  topography  of 
Coos  county. 

DESCRIPTION  OF  THE  EASTERN   BOUNDARY  OF  NEW  HAMPSHIRE. 

By  J.  H.  HUNTINGTON,  Commissioner  on  the  part  of  New  Hampshire  to  mark  anew 
the  boundary  between  New  Hampshire  and  Maine. 

The  eastern  boundary  of  New  Hampshire  was  for  many  years  a  matter 
of  fierce  controversy.  One  reason  of  this,  no  doubt,  was  owing  to  the 
fact  that  the  geography  of  the  country  was  little  known;  besides,  the 
same  territory  was  granted  to  several  different  parties,  both  by  the  king 
of  England  and  the  council  of  Plymouth.  It  was  finally  determined  by 
commissioners  appointed  by  the  king.  Their  report  was  as  follows  :  "As 
to  the  northern  boundaries  between  said  provinces,  the  court  resolve  and 


PHYSICAL    GEOGRAPHY. 

determine  that  the  dividing  line  shall  pass  up  through  the  mouth  of 
Piscataqua  harbor,  and  up  the  river  Newichwannock,  part  of  which  is 
now  called  Salmon  Falls,  and  through  the  middle  of  the  same  up  to  the 
fartherest  head  thereof,  and  from  thence  north  two  degrees  westerly,  until 
1 20  miles  be  finished  from  the  mouth  of  Piscataqua  harbor  aforesaid,  or 
until  it  meets  his  majesties  other  governments  ;  and  that  the  dividing 
line  shall  part  the  Isles  of  Sholes,  and  run  through  the  middle  of  the 
harbor  between  the  islands  to  the  sea  on  the  southerly  side,  and  that  the 
south-westerly  part  of  said  islands  shall  lye  in  and  be  accounted  part  of 
the  province  of  New  Hampshire."  To  the  order  of  Governor  Belcher, 
appointing  Walter  Bryent  to  survey  the  line,  was  affixed  the  following 
memorandum:  "The  true  north  2°  west  is  by  the  needle  north  8°  east, 
which  is  your  course."  Bryent  went  only  to  the  Saco,  and  it  is  supposed 
that  the  line  was  extended  to  the  north-east  corner  of  Shelburne,  in  1763, 
under  the  direction  of  Isaac  Rindge.  From  this  point  the  survey  was 
continued,  under  the  direction  of  a  committee  of  the  legislature,  to  the 
birch  tree  that  formerly  marked  the  northern  terminus  of  the  line, — the 
work  having  been  done  by  Jeremiah  Eames  and  Joseph  Cram. 

After  the  lapse  of  many  years,  when  Maine  had  been  erected  into  a 
separate  state,  provision  was  made  by  the  states  of  New  Hampshire  and 
Maine  to  have  the  line  resurveyed,  and  designated  by  suitable  monu 
ments.  Hon.  Ichabod  Bartlett,  of  Portsmouth,  and  Hon.  J.  W.  Weeks, 
of  Lancaster,  were  appointed  commissioners  on  the  part  of  New 
Hampshire. 

In  1858  the  line  was  again  surveyed.  Col.  Henry  O.  Kent  was  ap 
pointed  on  the  part  of  New  Hampshire.* 

The  northern  terminus  of  the  eastern  boundary  of  the  state  is  on  the 
water-shed  between  the  streams  flowing  northward  into  the  St.  Lawrence, 
and  the  streams  that  flow  southward  and  form  the  Magalloway.  The 
iron  post  that  marks  the  north-east  corner  of  the  state  is  also  on  the 
boundary  between  the  states  and  the  provinces,  and  the  point  is  said  to 
be  2,569  feet  above  the  level  of  the  sea. 

The  line   between  New  Hampshire  and  Maine  runs    south    2°  east. 


'  Since  penning  the  above,  Mr.  Huntington  has  attended  to  his  official  duty  of  remarking  this  boundary  line, 
ia  the  month  of  April,  1874.  C.  jj    jj. 


TOPOGRAPHY.  175 

For  the  first  fifteen  miles  there  is  an  unbroken  primeval  forest ;  then  for 
seven  miles  it  is  still  a  wilderness,  but  in  New  Hampshire  all  the  large 
timber  has  been  taken  off  by  lumbermen  ;  thence  southward,  clearings 
alternate  with  the  forest  until  we  reach  Chatham,  whence  southward  the 
country  is  settled.  At  first  the  descent  is  quite  rapid,  but,  on  reaching 
the  branches  of  the  Magalloway,  for  several  miles  the  country  is  com 
paratively  level.  But  it  soon  rises,  and  we  pass  over  Mt.  Abbott,  and 
here  we  touch  the  water-shed  between  the  Connecticut  and  the  Magallo 
way  ;  and  this  is  the  only  point  where  it  reaches  the  line  of  Maine. 
Leaving  Mt.  Abbott,  the  line  descends  somewhat,  but  in  a  mile  and  a 
quarter  it  reaches  the  summit  of  Mt.  C  arm  el,  which  is  the  highest  point 
on  our  eastern  boundary.  South  from  Mt.  Carmel  the  line  crosses  sev 
eral  branches  of  the  Magalloway,  passes  over  Prospect  hill,  and  the  next 
stream  of  any  considerable  size  is  the  Little  Magalloway.  From  this 
stream  the  line  passes  over  a  ridge  of  Bosebuck  mountain,  and  on 
on  the  southern  border  of  the  Academy  grant  it  crosses  Abbott  brook. 
Along  the  border  of  the  Academy  and  Dartmouth  College  grants  the 
contour  of  the  line  is  very  irregular,  but  Half  Moon  mountain  is  the  only 
noticeable  height.  South  of  this  mountain  the  line  crosses  an  open  bog, 
and  near  the  mouth  of  the  Swift  Diamond  it  twice  crosses  the  Magallo 
way  river,  and  it  crosses  it  a  third  time  near  the  north  border  of  Went- 
worth's  Location.  In  Errol  it  crosses  Umbagog  lake,  touching  two  points 
of  land  on  the  eastern  shore.  On  the  border  of  Cambridge,  the  first 
town  south  of  Umbagog  lake,  the  line  crosses  the  Hampshire  hills,  and 
several  branches  of  the  Androscoggin.  In  Success  it  crosses  the 
Chickwolnepy,  then  runs  along  the  western  slope  of  Goose  Eye  mountain, 
passes  over  Mt.  Ingalls,  and  then  on  the  border  of  Shelburne  it  descends 
to  the  Androscoggin.  Southward  it  crosses  a  ridge  of  land,  and  two 
miles  and  four  tenths  from  the  Androscoggin  it  strikes  Wild  river  ;  then 
with  varying  undulations  it  rises  until  it  reaches  the  summit  of  Mt. 
Royce,  whence  the  descent  is  very  precipitous  to  the  open  country  on 
Cold  river,  in  Chatham  and  Stow.  The  boundary  follows  the  valley  of 
this  stream  below  Chatham  centre,  and  on  the  south  line  of  Chatham  it 
crosses  Kimball  pond,  and  leaves  only  a  small  part  of  it  in  New  Hamp 
shire.  In  Conway  it  crosses  the  Saco,  thence  passes  over  a  gently  undu 
lating  country,  except  that  there  is  quite  a  hill  just  before  it  crosses  the 


176  PHYSICAL    GEOGRAPHY. 

Ossipee  river  on  the  border  of  Freedom.  Southward,  except  its  lakes,  the 
country  has  no  striking  characteristics.  The  line  touches  Province  pond, 
that  lies  principally  in  Effingham  and  Wakefield,  and  in  the  south  part  of 
the  latter  it  strikes  East  pond,  which  is  the  source  of  Salmon  Falls  river, 
and  this  is  the  boundary  to  the  ocean.  From  the  mouth  of  the  river  the 
line  runs  along  the  main  channel,  and  divides  the  Isles  of  Shoals  into 
unequal  parts.  The  largest  area,  including  Appledore  and  Smutty-nose 
islands,  belongs  to  Maine ;  but  Star  island,  which  has  the  chief  popula 
tion  of  the  islands,  belongs  to  New  Hampshire.  The  boundary  line 
passes  between  Smutty-nose  and  Cedar,  which  are  practically  one,  and 
Star  island.  J.  H.  HUNTINGTON. 

WESTERN  AND  SOUTHERN  BOUNDARIES. 

There  has  been  no  end  of  dispute  respecting  the  southern  boundary 
line.  The  south-eastern  portion  is  made  to  average  the  distance  of  three 
miles  northerly  from  the  Merrimack  river  for  about  thirty  miles.  From 
a  fixed  point,  a  "pine  tree"  between  Pelham,  N.  H.,  and  Dracut,  Mass., 
five  and  one  fourth  miles  east  of  the  Merrimack,  there  commences  a  line 
running  directly  to  Connecticut  river,  with  the  course  N.  86°  59'  37"  .5  W. 
The  distance  is  about  fifty-eight  miles.  According  to  a  plan  in  the  state 
library,  the  distance  between  the  south-east  corner  of  Hinsdale  and  a 
due  east  and  west  line  starting  from  the  pine  tree  and  ending  on  the 
west  bank  of  Connecticut  river,  is  942  rods.  The  difference  between 
the  true  and  magnetic  meridian  is  given  as  6°  20'  30".  The  plan  was 
drawn  by  E.  Hunt,  from  a  survey  made  August,  1825. 

The  western  boundary  of  the  state  has  been  fixed  at  low  water  on  the 
west  bank  of  Connecticut  river  as  far  as  the  north-east  corner  of  Ver 
mont.  Above  that  point  the  small  Hall's  stream  separates  the  state  from 
the  province  of  Quebec. 

ELEVATIONS  ALONG  THE  BOUNDARIES  OF  NEW  HAMPSHIRE. 

Height  of  tide  at  Portsmouth  is  8.6  feet ;  the  mean  or  half  tide  is,  in  all  cases,  the 
datum  to  which  our  altitudes  refer.  Head  of  tide  in  branches  of  the  Piscataqua  is 
at  Exeter,  Dover,  and  South  Berwick.

TOPOGRAPHICAL  DISTRICTS. 

I.  The  Connecticut  Valley.  The  limits  assigned  to  this  district  differ 
from  the  exact  area  drained  by  the  waters  of  the  hydrographic  system  of 
the  Connecticut.  Owing  to  the  presence  of  a  prominent  mountain  ridge 
six  or  seven  miles  back  from  the  river,  the  proper  valley  lies  in  the 
western  part  of  the  east  side  of  the  basin.  This  boundary  corresponds, 
also,  with  that  of  the  distinctive  agricultural  and  geological  character  of 
the  district.  In  general,  it  follows  on  the  east  line  of  the  ridge  of  slaty 
or  quartzose  hills  from  Winchester  to  Benton,  and  thence  the  eastern 
line  of  the  Connecticut  basin  to  Carroll ;  thence  it  continues  down  the 
VOL.  i.  25 


1/8  PHYSICAL    GEOGRAPHY. 

John's  river  valley  to  the  Connecticut  in  Dalton,  crosses  over  the  Con 
cord,  Vt.,  ridge  to  the  eastern  line  of  the  Passumpsic  river  basin,  which 
it  follows  around  to  Newark,  Sheffield,  and  Cabot.  From  here  the  line 
coincides  with  the  west  border  of  the  Connecticut  basin  to  Washington, 
Vt.;  thence  it  proceeds  west  of  south  directly  to  Proctorsville,  Vt.  Here 
it  turns  back  sharply  to  the  south-west  corner  of  Hartford,  whence  it 
proceeds  again  nearly  in  a  right  line  west  of  south  to  the  Massachusetts 
line  in  Halifax,  Vt.  This  area  comprises  about  3,200  square  miles,  and 
it  is  the  best  agricultural  district  east  of  the  Green  Mountains. 

Hinsdale  and  Vernon  combined — the  southern  border  towns  of  this 
district — make  a  natural  basin  about  seven  miles  in  diameter.  Hinsdale 
is  not  over  half  a  mile  wide  at  its  southern  extremity.  On  the  cast  bank 
of  the  Connecticut,  Foxden  mountain  bounds  the  district  as  far  as  the  vil 
lage  of  Hinsdale.  Here  the  Ashuelot  has  cut  a  deep,  narrow  chasm  into 
the  range.  The  high  land  continues  to  the  north,  culminating  along  the 
north  town  line,  in  Wantastiquit  or  Mine  mountain,  more  than  1,000 
feet  above  the  Connecticut.  The  more  eastern  part  of  this  mountainous 
pile  is  called  Daniel's,  and  East  mountain,  and  Bear  hill.  A  spur  runs 
down  opposite  Brattleborough  village,  about  a  mile  and  a  half,  close  to  the 
river's  bank.  As  seen  from  Brattleborough,  Wantastiquit  mountain  is 
rough  and  precipitous,  barely  giving  a  foothold  for  trees. 

On  the  Vernon  side  the  range  commences  directly  at  the  South  Vernon 
Railroad  junction,  and  follows  the  state  line  westerly  to  its  culmination 
in  the  south-west  corner  of  the  town,  perhaps  700  feet  above  the  river. 
Then  it  sweeps  around,  and  pursues  a  northerly  course  into  Brattle 
borough. 

Although  one  might  fancy  this  basin  an  extinct  volcanic  crater,  it  was 
not  this  resemblance  which  led  a  few  persons,  near  the  close  of  the 
eighteenth  century,  to  imagine  Wantastiquit  mountain  an  active  volcano. 
The  supposed  volcanic  phenomena  were  described  fully  in  the  Transac 
tions  of  the  American  Academy  of  Arts  and  Sciences,  Boston.  Dr. 
Timothy  Dwight  also  visited  the  locality  in  1798,  and  seems  to  have 
regarded  the  phenomena  as  "in  a  very  humble  degree  volcanic."  The 
site  of  the  supposed  eruption  is  about  one  hundred  and  fifty  feet  below 
the  summit.  A  loud  noise  had  been  heard,  and  on  this  spot  a  black  iron 
ore,  much  like  scoria,  seemed  to  have  been  thrown  about.  From  an 


TOPOGRAPHY. 

excavation,  iron  ochre  and  the  "vitrified  ore"  were  obtained  in  considera 
ble  amount.  The  noise  probably  came  from  the  decomposition  of  pyrites, 
while  the  ores  are  such  as  slightly  resemble  artificial  slag,  though  formed 
by  concretion  or  segregation  from  moist  clay. 

The  high  land  continues  through  Chesterfield,  Westmoreland,  and  Wai- 
pole, — cut  down  to  830  feet  in  Westmoreland  for  the  passage  of  the 
Cheshire  Railroad,  and  to  the  level  of  the  Connecticut  just  below  Bellows 
Falls.  On  the  Vermont  side  the  slate  range  of  Guilford  has  been  cut 
through  by  West  river  in  Brattleborough  and  Dummerston.  Just  to  the 
north  there  is  the  conical  granitic  peak  of  Black  mountain,  which  is  the 
culmination  of  the  hilly  ridge  from  Bellows  Falls.  Both  the  Vermont 
and  New  Hampshire  ridges  close  in  at  Bellows  Falls,  making  Kilburn 
peak  in  Walpole.  This  is  about  1200  feet  high,  and  is  more  ragged  and 
precipitous  than  Wantastiquit.  It  is  an  outlier  of  an  older  formation, 
upon  which  the  slates  were  originally  deposited,  and  then  elevated  so  as 
to  stand  nearly  upon  their  edges.  Three  streams  have  cut  around  this 
mountain;  the  Connecticut  and  Saxton's  rivers  on  the  west,  and  Cold 
river  along  its  south-eastern  slope.  My  father  supposed  the  Bellows 
Falls  gorge  was  worn  out  subsequently  to  the  formation  of  the  pot-holes 
in  Orange,  along  the  track  of  the  Northern  Railroad.  The  occurrence  of 
the  pot-holes,  however,  can  be  explained  more  simply  otherwise. 

The  third  of  the  basins  is  not  quite  so  regular.  On  the  east  side 
there  commences  a  series  of  mountains  of  quartz,  in  Charlestown, 
Acworth,  Unity,  Claremont,  Croydon,  Grantham,  Plainfield,  East  Leba 
non,  Hanover,  Lyme,  Orford,  and  Piermont,  into  Benton.  The  basin 
may  terminate  in  Cornish,  opposite  Mt.  Ascutney.  In  Charlestown  we 
have  Page,  Sam's,  and  Prospect  hills.  Perry's  mountain  makes  a  range 
between  Unity  and  Charlestown,  cut  through  by  Little  Sugar  river.  The 
land  then  rises  into  Fifield  hill,  Unity,  and  Bible  hill,  Claremont.  At 
this  point  Sugar  river  valley  intervenes,  and  carries  the  proper  Connecti 
cut  slope  farther  east  than  the  district  under  consideration.  On  the 
north  the  mountains  increase  their  strength,  and  the  long  and  elevated 
Croydon  and  Grantham  range  pushes  on  to  the  Mascomy  lake  in  East 
Lebanon.  Green  and  Bald  mountains  in  Claremont  are  the  foot  hills  of 
this  range.  Barber's  mountain  occupies  a  bend  in  the  river  in  West 
Claremont.  In  Cornish,  Parsonage,  Smith's,  Kenyon,  and  Dingleton 


I  SO  PHYSICAL    GEOGRAPHY. 

hills  make  a  series  of  elevations  crossing  over  towards  Ascutney,  the 
highest  peak  in  the  Connecticut  district,  and  crowding  the  river. 

On  the  Vermont  side  the  range  of  hills  is  not  high  below  Ascutney, 
and  notches  have  been  excavated  for  the  passage  of  William's  and  Black 
rivers.  Mt.  Ascutney  is  a  conical  mountain,  mostly  of  eruptive  granite, 
protruded  through  the  calcareous  range,  and  rises  to  about  3,168  feet 
above  the  sea.  It  is  as  much  isolated  in  position  as  it  is  elevated  above 
the  ridge  of  which  it  is  the  culmination. 

Perhaps  a  fourth  basin  may  be  said  to  commence  with  Ascutney,  and 
terminate  in  the  narrows  above  Fairlee  and  Orford. 

There  is  a  gap  at  East  Lebanon  for  the  passage  of  Mascomy  river, 
above  which  the  Mascomy  lake  basin  expands  as  extensively  as  the  Sun- 
apee  lake  country  at  the  head  of  Sugar  river.  The  quartzite  range  of 
Moose  mountain  is  broken  at  the  south  line  of  Lyme,  and  then  rises 
gradually  to  form  Mt.  Cuba  in  Orford,  2,273  feet  above  the  sea.  On  the 
west  slope  of  Cuba,  Lime  and  Bass  hills,  with  Sunday  and  Soapstone 
mountains,  constitute  a  ridge  extending  close  on  to  the  Connecticut. 

On  the  Vermont  side  there  are  no  prominent  hills  adjacent  to  the  river. 
The  valley  of  White  river  is  the  deepest  and  most  extensive  yet  traversed, 
as  it  is  the  main  valley  threading  north-westerly  towards  Montpelier  and 
Burlington,  and,  consequently,  the  route  of  the  Central  Vermont  Rail 
road.  Our  limits  are  here  much  broadened  to  take  in  the  hilly  calcareous 
country  of  all  the  eastern  townships  of  upper  Windsor  and  Orange  coun 
ties.  The  proper  ridge  would  extend  from  Beaver  hill  in  Norwich,  and 
Copperas  hill  in  Strafford,  towards  Washington,  Orange,  and  the  elevated 
gores  of  land  west  of  Peacham,  into  Cabot.  Thetford  hill  is  on  the  sub 
range  next  to  the  river,  which  is  cut  entirely  through  farther  north  for 
the  outlet  of  Fairlee  pond,  and  crowds  the  Connecticut  in  Sawyer's 
mountain  next  the  Soapstone  hill.  Opposite  Orford  village  this  makes  a 
precipitous  ledge.  A  view  of  the  closing  in  of  Sawyer's  and  Soapstone 
mountains  is  given  in  Fig.  20,  in  which  the  steep  escarpment  of  the 
former  and  the  more  undulating  outline  of  the  latter  mountain  on  the 
right  hand  side  may  be  distinctly  discerned.  In  the  foreground  are 
alluvial  terraces,  the  view  being  that  seen  from  Bissell's  hill,  a  little  north 
of  Orford  village. 

The  Haverhill  section  of  the  valley  next  commands  attention.     The

valley  widens  so  as  to  give  a  great  breadth  of  alluvial  meadow  between 
the  villages  of  Haverhill  and  Newbury,  more  so  than  at  any  other  point  in 
the  valley,  the  nearest  approach 
to  it  below  being  in  Walpole  and 
Westminster.  These  meadows 
are  two  miles  in  width,  and  the 
river  is  very  crooked,  flowing 
nearly  twice  as  far  as  the  linear 
distance  from  Howard's  island 
to  the  south  line  of  Haverhill. 
From  the  village  of  Newbury, 
\vhich  is  located  upon  a  beauti 
ful  terrace,  one  can  see  the  hills 
rise  higher  and  higher  back  of 
Haverhill,  to  the  lofty  ridge  of 
Moosilauke,  the  south-west  ex 
tension  of  the  White  Moun 
tains.  There  are  five  peaks  in 
a  line  below  the  highest  ridge, 
which  are  distinguished  by 
their  baldness,  and  known  as 
Owl's  Head,  Blueberry,  Hog's 
Back,  Sugar  Loaf,  and  Black 
mountains. 

On  the  Vermont  side  the 
hills  are  scattered,  abundant, 
and  are  in  no  way  remarkable 
directly  opposite  the  Haverhill 
section  ;  but  the  range  from  Knox  mountain  in  Orange  to  Cow  hill  in 
Peacham  is  the  counterpart  of  the  Moosilauke  group,  a  little  farther  north. 
The  Ammonoosuc  section  may  embrace  all  that  lies  east  of  the  Con 
necticut  as  far  north  as  Dalton  above  Haverhill.  The  calcareous  rocks 
mostly  disappear  to  make  way  for  the  older  and  harder  green  schist, 
which  gives  a  different  shape  to  the  hills.  This  is  where  the  Connecticut 
bends  north-east  and  east,  and  in  the  angle  of  the  bend  is  the  Gardner 
mountain  range,  reaching  nearly  2,000  feet.  Landaff,  Lisbon,  and  Little- 


1 82  PHYSICAL    GEOGRAPHY. 

ton  give  slaty  eminences  in  Pond,  Pine,  Sugar,  Eustis,  and  portions  of 
Mann's  hills.  The  gneissic  eminences  are  Bronson  and  Ore  hills,  Green 
mountain,  Iron  Ore  hill,  and  Moody  ledge  in  Landaff,  and  numerous 
unnamed  summits  in  the  western  part  of  Bethlehem. 

The  Connecticut  has  excavated  a  passage  through  the  Gardner  moun 
tain  range,  in  what  is  known  as  Fifteen-miles  falls,  from  Barnet  to  South 
Lancaster,  where  the  water  descends  nearly  four  hundred  feet.  The 
valley  is  narrow,  rocky,  and  mostly  devoid  of  superficial  deposits  above 
the  drift.  In  contrast  with  this  is  the  valley  of  the  Ammonoosuc,  between 
Woodsville  and  Bethlehem,  which  is  full  of  deposits  of  modified  drift. 
These  differences  have  given  rise  to  the  inquiry  whether  the  Connecticut 
may  not  have  flowed  formerly  through  the  Ammonoosuc  valley,  passing 
over  the  water-shed  at  Whitefield. 

The  Passumpsic  section  is  located  in  a  fertile  calcareous  region,  and 
abounds  in  deposits  of  sand,  gravel,  and  clay.  It  lies  entirely  in  Vermont. 
On  the  east  are  the  slate  hills  of  Kirby  and  Waterford,  which  are  pro 
longed  into  the  schist  eminences  of  Lunenburg,  Victory,  and  Granby; 
and  there  are  gneissic  and  granitic  mountains,  in  the  same  connection, 
following  around  by  Willoughby  lake  to  Barton.  The  notch  between  Mts. 
Horr  and  Pisgah,  in  Westmore,  is  the  most  conspicuous  feature  in  the 
landscape  of  all  northern  Vermont ;  and  the  closer  it  is  approached  the 
more  irregular  it  appears.  These  two  hills  rise  precipitously  1,800  feet 
above  Willoughby  lake,  having  only  the  water  between  them,  and  are 
less  than  a  mile  apart  near  the  upper  end  of  the  lake. 

The  country  rises  from  Crystal  lake,  in  Barton,  to  Sheffield ;  and  the 
water-shed  between  the  Passumpsic  and  Lamoille  rivers,  through  Shef 
field,  Wheelock,  and  Walden,  coincides  with  the  western  border  of  the 
Connecticut  district.  It  is  nearly  all  susceptible  of  cultivation,  though 
abounding  in  forests ;  and  the  rocks  are  nearly  all  calcareous. 

II.  Coos  and  Essex  District.  This  lies  at  the  extreme  north  of  the  area 
of  our  explorations.  It  is  all  mountainous,  sparsely  settled,  largely  cov 
ered  with  forests,  yet  containing  many  tracts  of  great  fertility.  It  is  the 
most  diversified  of  all  the  topographical  districts.  The  main  water-shed 
of  New  Hampshire  passes  through  the  middle  portion  from  Randolph  to 
Mt.  Carmel ;  and,  in  Essex  county,  there  is  a  similar  ridge  from  Lunen 
burg  to  the  state  line.  The  Grand  Trunk  Railway  passes  through  the

lowest  line  of  depression  that  can  be  found  in  this  area.  Commencing  at 
the  boundary  of  Quebec  and  Vermont,  with  1,232  feet  elevation  above 
the  sea,  it  rises  to  1,357  feet  at  Norton,  and  thence  descends  to  Connec 
ticut  river  at  North  Stratford,  which  is  915  feet.  Following  the  river 
down  to  Groveton,  there  may  be  a  fall  of  twenty  feet.  The  road  pro 
ceeds  up  the  Upper  Ammonoosuc,  attaining  1,080  feet  at  Milan  water- 
station.  Thence  it  descends  to  the  Androscoggin  valley,  passing  into 
Maine  with  an  altitude  of  713  feet. 


Fig.  21. — MX.  LYON,  FROM  GUILDHALL  FALLS. 

At  the  entrance  to  the  Upper  Ammonoosuc  valley  there  stands  a  bold 
ridge,  known  formerly  as  Cape  Horn,  in  Northumberland.  Mr.  Hunting- 
ton  has  proposed  to  designate  it  as  Mt.  Lyon,  in  honor  of  J.  E.  Lyon, 
president  of  the  Boston,  Concord  &  Montreal  Railroad.  The  ridge  is  too 
precipitous  to  be  cultivated.  A  sketch  of  it  is  given  in  Fig.  21. 

There  are  two  prominent  lines  of  depression,  running  in  a  north-east 
erly  direction,  in  the  Coos  region.  The  first  follows  the  Androscoggin, 
from  Shelburne  to  Umbagog  lake,  713  to  1,256  feet;  the  second  follows 
the  "Connecticut  river,  from  830  feet  at  Dalton  to  1,619  feet  at  Connec 
ticut  lake,  and  thence  to  2,146  feet  at  the  gap  above  the  source  of  the 
Connecticut.  All  the  rest  of  this  district  is  more  elevated  than  these 
three  lines  of  depression. 

Both  the  elevation  and  the  high  latitude  of  this  district  render  the 
climate  of  this  district,  including  the  White  Mountains,  the  most  rigorous 
of  any  in  the  state.  Plants  that  suffer  from  protracted  winters  cannot 
therefore  be  successfully  cultivated  here.  Nothing  is  done  with  the  vine, 


184  PHYSICAL    GEOGRAPHY. 

and  scarcely  anything  with  fruit  trees.  The  staple  crops  are  grain,  oats, 
and  potatoes,  no  county  in  the  United  States  yielding  better  results  for 
the  latter  article  than  this.  On  this  account  there  are  many  manufacto 
ries  of  potato  starch  here. 

As  the  topography  of  this  district  is  of  special  geological  interest,  a 
whole  chapter  will  be  devoted  to  it,  prepared  by  Mr.  Huntington. 

III.  White  Mountain  Area.  The  White  Mountains  of  New  Hamp 
shire  cover  an  area  of  1,270  square  miles,  bounded  by  the  state  line  on 
the  east,  the  Androscoggin  river  and  the  Grand  Trunk  Railway  on  the 
north-east  and  north,  the  Connecticut  river  valley,  or  an  irregular  line 
from  Northumberland  to  Warren,  on  the  west,  the  less  elevated  region  of 
Baker's  river  on  the  south-west,  the  Pemigewasset  river  and  the  lake 
district  on  the  south.  The  Pemigewasset  valley  makes  a  prominent 
notch  in  it  in  Thornton  and  Woodstock.  The  Saco  river  cuts  the  White 
Mountains  into  nearly  equal  parts  ; — and  it  may  be  convenient  sometimes 
to  speak  of  what  lies  on  the  east  and  the  west  sides  of  this  stream. 

The  mountains  may  be  grouped  in  ten  sub-divisions,  i.  Mt.  Starr 
King  group.  2.  Mt.  Carter  group.  3.  Mt.  Washington  range,  with  a 
Jackson  branch.  4.  Cherry  Mountain  district.  5.  Mt.  Willey  range. 
6.  Mts.  Carrigain  and  Osceola  group.  7.  Mt.  Passaconnaway  range. 
8.  Mts.  Twin  and  Lafayette  group.  9.  Mts.  Moosilauke  and  Profile 
division.  10.  Mt.  Pequawket  area.  Divisions  2  and  3  may  be  termed 
"Waumbek"  for  convenience,  and  divisions  5,  6,  and  8  may  receive  the 
name  of  "Pemigewasset." 

Considered  as  a  whole,  the  main  range  would  commence  with  Pine 
mountain  in  Gorham,  follow  the  Mt.  Washington  ridge,  cross  the  Saco 
below  Mt.  Webster,  and  continue  south-westerly  by  Nancy  mountain,  Mt. 
Carrigain,  Mt.  Osceola,  and  terminate  in  Welch  mountain  in  Waterville. 
Another  considerable  range  may  be  said  to  commence  with  the  Sugar 
Loaves  in  Carroll  and  Bethlehem,  and  continue  westerly  by  the  Twin 
mountains,  Lafayette,  Profile,  Kinsman,  and  Moosilauke.  A  third  of  some 
consequence  might  embrace  the  Carter  range,  with  Iron  mountain  in 
Bartlett.  These  mountain  groups  differ  much  in  geological  character, 
age,  and  marked  topographical  features. 

i.  Mt.  Starr  King  Group.  This  has  not  been  explored  very  exten 
sively,  and  it  is  not  so  much  frequented  by  visitors  as  most  of  the  other

districts.  It  is  embraced  in  the  remote  portions  of  the  towns  of  Gorham, 
Randolph,  Jefferson,  Lancaster,  Stark,  Milan,  Berlin,  and  the  whole  of 
Kilkenny.  It  may  be  bounded  by  the  Upper  Ammonoosuc  and  Andros- 
coggin  rivers  on  the  north  and  east,  by  Moose  and  Israel's  rivers  on  the 
south,  and  the  Connecticut  slope  on  the  west.  From  the  extreme  out 
lying  foot  hill  on  the  west  line  of  Stark  to  Gorham,  the  longest  diameter 
of  this  group,  the  distance  is  sixteen  miles.  The  greatest  width  is  thir 
teen  miles,  or  from  Jefferson  hill  to  Milan  water-station.  The  shape  of 
the  area,  as  mapped,  is  oval-elliptical,  being  more  pointed  at  the  north 
than  the  south.  The  area  may  comprise  150  square  miles. 

The  Upper  Ammonoosuc  river  flows  in  a  broad  valley  in  Randolph 
and  Berlin,  and  thereby  divides  the  group  into  two  parts.  The  source, 
called  the  Pond  of  Safety,  is  nearly  900  feet  above  Milan  water-station, 
and  there  is  a  depression  in  the  ridge  in  the  south  towards  Jefferson. 
For  geological  reasons,  we  understand  that  the  northern  portion  of  the 
Starr  King  region  was  once  an  immense  plateau,  and  the  numerous 
valleys  in  it  now  are  the  result  of  atmospheric  erosion.  Not  less  than 
seven  streams  have  notched  in  the  edge  of  this  plateau, — the  three  most 
prominent  erosions  being  from  Berlin,  Stark  (Mill  brook),  and  Lancaster. 
There  is  a  central  ridge  through  Kilkenny,  the  Pilot  mountain  range, 
connected  by  a  valley  with  Mt.  Starr  King  in  Jefferson.  A  branch 
diverges  from  this  range  to  Pilot  mountain  in  Stark,  formerly  ascended 
by  a  foot-path  from  Lost  Nation.  Green's  ledge  and  Black  mountain 
are  spurs  to  the  east  from  the  Pilot  range. 

From  Mt.  Starr  King  to  Berlin  Falls  there  runs  an  irregularly  curved 
range.  It  is  composed  of  Pliny,  Randolph,  and  Crescent  mountains,  and 
Mt.  Forest.  Section  X  passes  through  the  centre  of  this  district  from 
Berlin  Falls  to  Lancaster,  from  which  the  reader  may  learn  the  irregulari 
ties  of  the  surface-profile.  Mts.  Starr  King,  Pilot,  and  Randolph  are  the 
culminating  points,  being  3,800,  3,640,  and  3,043  feet  respectively.  The 
region  is  entirely  covered  by  a  forest. 

2.  Mt.  Carter  Group.  This  lies  in  Shelburne,  Bean's  Purchase,  Chat 
ham,  and  Jackson,  and  is  the  least  known  of  all  the  mountain  districts. 
I  do  not  find  any  explorer  of  it  anxious  to  continue  his  investigations 
therein.  The  mountains,  however,  are  like  all  other  elevated  tracts  of 
land  far  away  from  habitations.  There  seems  to  be  a  heavy  range  from

Gorham  to  Jackson,  quite  near  the  Peabody  and  Ellis  valleys,  while  on 
the  east  the  slope  towards  the  Androscoggin  is  quite  gradual.  Mt.  Moriah 
is  one  of  the  more  northern  peaks  of  this  chain.  Fig.  19,  p.  146,  will 
show  its  features.  The  view  is  from  a  point  in  the  Androscoggin  valley 
in  Shelburne.  The  distance  is  so  great  that  the  stern,  rugged  features  of 
the  mountain  are  much  softened.  Wild  river  occupies  a  broad  valley 
in  Bean's  Purchase,  trending  north-easterly.  The  highest  part  of  the 
Carter  range  lies  next  the  Peabody  river ;  and  the  western  slope  is  much 
steeper  than  the  eastern.  A  view  of  Mt.  Carter,  from  a  point  south  of 
the  village  of  Gorham,  is  quite  impressive,  as  exhibited  in  the  sketch. 


Fig.   22. — MT.    CARTER,   FROM   GORHAM. 

Imp  mountain  lies  between  Moriah  and  Carter.  There  is  a  very  deep 
notch  between  Height's  and  Carter's  mountains,  in  the  edge  of  Jackson. 
The  east  branch  of  Ellis  river  flows  from  it  south-easterly ;  and  the  range 
courses  easterly  so  as  to  form  the  entire  westerly  and  southerly  rim  of 
the  Wild  river  basin.  Several  tributaries  flow  to  Wild  river  on  the  north ; 
and  others  to  the  Saco  on  the  south  of  this  easterly  range.  It  curves 
more  northerly  near  the  Maine  line,  terminating,  so  far  as  New  Hamp 
shire  is  concerned,  in  Mt.  Royce,  directly  on  the  border. 


TOPOGRAPHY.  l8/ 

The  Carter  mountain  group  sends  five  spurs  into  Jackson  and  Chatham. 
The  first  is  the  continuation  of  Height's  mountain,  adjoining  the  Pinkham 
road,  to  Spruce  and  Eagle  mountains,  near  Jackson  village.  The  second 
comes  down  from  Carter  mountain,  to  include  Black  and  Tin  mountains. 
The  third  spur  takes  in  Doublehead  mountain,  and  is  bordered  easterly 
by  the  east  branch  of  the  Saco  and  the  Wildcat  branch.  Near  the  line 
of  Bean's  Purchase  and  Chatham  lies  Baldface  mountain,  3,600  feet  high, 
from  which  run  the  fourth  and  fifth  spurs.  The  fourth  comprises  Sable 
mountain,  in  Jackson,  and  its  foot  hills.  The  fifth  is  composed  of 
Mts.  Eastman  and  Slope,  in  Chatham,  which  run  into  the  Pequawket 
area. 

3.  Aft.  Washington  Range.  The  main  range  of  Mt.  Washington 
extends  from  Gorham  to  Bartlett,  about  twenty-two  miles.  The  culmi 
nating  point  is  central,  with  a  deep  gulf  towards  Gorham,  a  slope  on  the 
north,  formed  partially  by  the  westerly  Mt.  Deception  range,  which  also 
produces  the  broad  Ammonoosuc  valley  on  the  west,  in  connection  with 
the  axial  line  of  summits.  On  the  south  there  are  two  principal  valleys, 
the  more  westerly  occupying  the  depression  of  Dry  or  Mt.  Washington 
river,  and  the  easterly  passing  down  the  slope  of  Rocky  branch,  which 
travels  easterly  near  its  termination,  so  as  to  be  parallel  with  the  Saco  in 
Bartlett.  Starting  with  the  Androscoggin  valley,  the  range  commences 
in  the  low  Pine  mountain.  In  the  south-east  corner  of  Gorham  this  is 
intersected  by  the  pass  of  the  Pinkham  road  between  Randolph  and  the 
Glen  house.  Next,  the  land  rises  rapidly  to  the  top  of  Mt.  Madison,  5,400 
feet.  The  range  now  curves  westerly,  passing  over  the  summits  of 
Adams,  Jefferson,  and  Clay.  The  gap  between  Clay  and  Washington  is 
the  best  place  to  behold  the  deep  abyss  in  which  the  west  branch  of 
Peabody  river  takes  its  rise.  From  Washington,  one  can  easily  discern 
the  east  rim  of  the  Great  Gulf,  for  upon  it  is  located  the  carriage-road 
to  the  Glen  house.  From  the  Lake  of  the  Clouds,  and  the  eminence 
south  of  Tuckerman's  ravine  to  Madison,  it  is  easy  to  imagine  the  area 
an  elevated  plateau, — of  which  Bigelow's  lawn  is  a  portion, — out  of  which 
Washington  may  rise  800  feet.  On  the  east  of  Washington,  two  deep 
ravines  have  been  excavated, — Tuckerman's  and  Huntington's.  The  first 
runs  easterly,  and  holds  the  head  waters  of  Ellis  river ;  the  second  com 
mences  at  the  southernmost  angle  of  the  carriage-road,  at  the  fifth  mile

post,  and  runs  towards  the 
first.  The  frontispiece  will 
show  the  character  of  these 
two  valleys,  and  their  rela 
tions  to  the  adjoining  moun 
tains. 

The   shape   of  Jefferson 
and  the  foot  of  Adams,  as 
seen    from     the     Half-way 
house,  are  indicated  in  Fig.

must  realize  that  they  represent  2,000  feet  of  altitude  above  the  station 
of  the  observer.

The  deep  valley  on  the  left  is  Tuckerman's  ravine.     Huntington's  ra 
vine,  the  head  of  Peabody  river,  lies  back  of  a  low,  woody  ridge  terminating 


TOPOGRAPHY.  189 

just  behind  the  prominent  spruce  tree  in  the  centre  of  the  foreground. 
The  tops  of  the  ridge  back  of  Huntington's  ravine,  and  the  one  to  the 
extreme  left,  mark  the  edge  of  the  5,000  feet  plateau  about  Mt.  Washing 
ton.  Mt.  Washington  itself  rises  above  the  plateau  a  little  to  the  right 
of  the  centre  of  the  sketch.  The  projection  between  the  two  ravines  is 
known  as  Davis's  Spur. 

These  and  other  topographical  features  of  the  Mt.  Washington  range 
are  well  represented  upon  a  map  designed  to  illustrate  the  Alpine  and 
sub-Alpine  districts  of  Waumbek,  which  will  appear  in  the  chapter  upon 
the  distribution  of  insects  in  New  Hampshire. 

Past  Mt.  Washington  the  main  range  descends  to  the  pass  of  the  Lake 
of  the  Clouds, — the  source  of  the  Ammonoosuc  river, — 5,000  feet  high. 
The  first  mountain  is  Monroe — a  double,  ragged  peak  scarcely  ever  visited, 
the  road  passing  around  it.  Next  follow  in  order  Mts.  Franklin,  Pleasant, 
Clinton,  Jackson,  and  Webster.  The  gaps  between  all  these  are  small. 
Mt.  Pleasant  may  be  recognized  by  its  dome  shape.  Fig.  25  will  give  a 
good  idea  of  the  ranges  as  seen  from  near  the  White  Mountain  house  in 
Carroll.  The  last  peak  on  the  right  is  a  fragment  of  Jackson.  It  lies  a 
little  back  from  the  line ;  and  the  road  to  Crawford's  lies  in  front  of  it. 


Fig.    25. — MT.    WASHINGTON,   FROM   NEAR   FABYAN'S. 

The  valley  in  front  is  the  broad  basin  of  the  Ammonoosuc  ;  and  the 
lower  slopes  of  the  Deception  range  on  the  left.     Mt.  Webster  is  a  long

mountain  with  precipitous  flank  on  the  side  towards  the  Saco.  It  is 
directly  opposite  the  Willey  house.  It  is  one  of  the  main  features  of  the 
notch. 

The  east  flank  of  the  mountains,  from  Monroe  to  Webster,  is  washed 
by  the  powerful  Mt.  Washington  river,  which  forms  the  central  line  of 
Cutts's  grant,  heading  in  Oakes's  gulf.  It  is  the  proper  continuation  of 
the  Saco  valley,  its  source  being  several  miles  farther  away  than  the  small 
pond  near  Crawford's.  In  dry  seasons  the  water  may  be  low,  which  fact, 
in  connection  with  a  broad,  gravelly  expanse  of  decomposed  granite  near 
the  lower  end  of  the  valley,  gave  rise  to  the  early  appellation  of  "  Dry 
river."  Dr.  Bemis  proposed  that  it  receive  the  name  of  Mt.  Washington 
river. 

From  the  east  side  of  Oakes's  gulf,  or  the  continuation  of  Bigelow's 
lawn,  two  ranges  course  southerly.  The  western  follows  the  Saco  to  just 
opposite  Sawyer's  rock,  having,  in  the  lower  part  of  its  course,  Giant's 
stairs,  Mt.  Resolution,  Mt.  Crawford,  Mt.  Hope,  and  "Hart's  ledge,"  of

Boardman's  map.     Two  heliotypes  show  the  shape  of  Crawford.     When 
seen  from  the  north-west,  a  little  below  the  Willey  house,  the  summit 


TOPOGRAPHY.  19 1 

projects  northwardly,  like  the  head  of  a  wild  beast,  overhanging  the 
granitic  slope.  From  near  Dr.  Bemis's  residence,  one  gets  the  idea  of  a 
broad,  conical  peak,  furrowed  by  a  temporary  stream.  There  have  been 
avalanches  down  the  west  side,  where  very  large  rocks  have  bounded  into 
the  middle  of  the  Saco  flood  plain,  175  feet  at  a  single  leap.  The  over 
hanging  character  of  Mt.  Crawford  may  be  somewhat  exaggerated  in  the 
figure;  but  any  one's  pencil  is  tempted  to  distort  somewhat  the  char 
acteristic  features  of  summits,  in  order  to  give  strangers  the  proper 
impression  of  their  effect  in  the  landscape. 

The  more  easterly  range  is  elevated  but  is  not  conspicuous,  and  con 
sequently  is  not  named.  It  is  flanked  by  Rocky  Branch  on  the  west  and 
by  Ellis  river  on  the  east.  Near  Jackson  village  it  curves  easterly,  and 
terminates  in  the  granitic  Iron  mountain.  Between  Sawyer's  rock  and 
the  mouth  of  Rocky  Branch  there  is  a  range  running  easterly,  with  a 
spur  towards  Mt.  Crawford,  separated  by  Razor  brook  from  the  Mt.  Hope 
ridge.  It  lies  between  the  southern  termini  of  the  two  divergent  ranges 
pointing  southerly  from  Bigelow's  lawn.  Its  precipitous  character  is 
shown  in  the  sketch  placed  at  the  end  of  Chapter  I. 

4.  Cherry  Mountain  District.  The  Mt.  Deception  range  consists  of 
four  peaks, — Mt.  Mitten,  Mt.  Dartmouth,  Mt.  Deception,  and  Cherry 
mountain,  formerly  called  Pondicherry.  It  is  separated  by  a  considerable 
valley  from  Mt.  Jefferson,  and  its  gentler  slope  lies  on  the  northern  flank 


Fig.  27. — CHERRY  MOUNTAIN,  FROM  TWIN  MOUNTAIN  HOUSE. 


towards    Israel's    river.     The  road  from    Fabyan's  to  Jefferson    passes 
between  Cherry  and  Deception.     The  range  runs  nearly  at  right  angles 


192  PHYSICAL    GEOGRAPHY. 

to  the  main  mountain  axis.  Cherry  mountain  has  a  northerly  spur  of 
large  dimensions,  called  Owl's  Head.  A  view  of  Cherry  mountain,  as 
seen  from  a  point  half  a  mile  west  of  the  Twin  Mountain  house,  is  pre 
sented  in  Fig.  27.  The  northern  part  of  the  range  seems  to  be  the 
highest. 

5.  Mt.  Willcy  Range.  This  starts  from  near  the  White  Mountain 
house  in  Carroll,  and  terminates  in  Mt.  Willey.  Its  northern  terminus 
is  low,  and  the  highest  peak  is  at  the  southern  end  of  the  range.  Six 
granitic  summits  may  be  counted  before  reaching  the  high  summit  of 
Mt.  Tom,  just  behind  the  Crawford  house.  This  peak  is  high  and  impos 
ing,  as  seen  from  the  vicinity  of  the  Crawford  house.  The  stream  form 
ing  Beecher's  cascade  passes  between  Tom  and  the  next  summit  south. 

This  latter  peak  has  been  named  Mt.  Lincoln,  in  honor  of  the  late 
President  Abraham  Lincoln,  by  some  unknown  person.  This  title  has 
been  applied  to  stereoscopic  views  of  it  :  but  if  we  apply  to  the  naming 
of  mountains  the  canons  of  nomenclature  required  for  scientific  terms, 
it  will  be  impossible  to  retain  the  name  of  Lincoln,  because  it  has  been 
preoccupied  at  Franconia.  It  is  doubtful  whether  Mr.  Fifield  proposed 
to  call  the  nameless  peak  Lincoln  in  advance  of  photographic  usage  at 
Crawford's  ;  but  the  fact  of  its  prior  publication  in  a  map  is  sufficient 
reason  for  adopting  the  name  in  Franconia,  and  hence  to  reject  the  appel 
lation  in  the  other  case.  I  propose,  therefore,  the  name  of  Mt.  Field  for 
the  eminence  near  the  Crawford  house,  in  honor  of  the  worthy  gentleman 
(Darby  Field)  who  first  ascended  Mt.  Washington  in  1642,  and  will  use 
it  upon  the  map  and  in  the  descriptions  of  this  report.  See  p.  44. 

From  Mt.  Field  to  Mt.  Willey  the  high  land  is  continuous,  reaching  an 
elevation  of  4,300  feet.  It  then  drops  off  abruptly,  and  terminates,  while 
the  water-shed  continues  into  the  Carrigain  district.  Ethan's  pond  is 
situated  a  little  to  the  south-west  of  the  base  of  the  precipice.  This  is 
the  extreme  head  of  the  waters  flowing  into  Merrimack  river.  The  Field- 
Willey  range  is  directly  opposite  to  Mt.  Webster;  and  the  intervening 
valley  is  the  most  striking  part  of  the  White  Mountain  notch.  The  head 
of  the  notch  is  formed  by  Mt.  Willard,  only  about  550  feet  above  the 
Crawford  plain.  It  is  covered  by  trees  on  the  north  side ;  and  the  south 
is  precipitous,  looking  down  the  valley  of  the  Saco.  One  of  our  helio- 
types  shows  this  view,  which  is  one  of  great  beauty.

6.  Carrigain  and  Osceola  Group,  Across  from  Mt.  Webster  the  Mt 
Washington  range  is  continued  in  the  mountains  culminating  in  Carri 
gain,  4,678  feet  high.  This  is  a  lofty,  conical  summit,  occupying  the  most 
conspicuous  position  in  the  horizon  when  seen  from  Mts.  Washington, 
Crawford,  Pequawket,  Moosilauke,  and  Lafayette.  Two  summits  in  this 
line,  north  of  Carrigain,  have  names,  viz.,  Mts.  Nancy  and  Lowell, — the 
latter  after  Abner  Lowell,  of  Portland,  and  known  heretofore  as  Brick- 
house  mountain.  There  is  an  interesting  gap  between  Lowell  and  Carri 
gain,  represented  in  the  chapter  on  Scenery.  The  original  of  this  sketch 
was  prepared  by  George  F.  Morse,  of  Portland,  who  visited  Mt.  Carrigain, 
in  company  with  G.  L.  Vose,  in  1869.  The  depth  and  impressiveness  of 
the  notch  remind  one  of  the  great  gap  between  Willey  and  Webster.  It 
would  be  a  good  route  for  a  carriage-road  from  Bartlett  over  to  the  east 
branch  of  the  Pemigewasset.  Nearly  west  from  Carrigain  is  Mt.  Hancock 
{Pemigewasset  of  Guyot).  It  is  nearly  as  high  as  Carrigain  (4,420  feet), 
and  falls  off  gradually  to  the  forks  of  the  East  Branch  on  the  east  line  of 
Lincoln.  The  space  between  Carrigain  and  Osceola  abounds  in  granite 
mountains,  often  with  precipitous  sides.  Tripyramid  may  represent  a 
spur  (if  not  an  isolated  group)  from  them,  running  towards  Whiteface, 
Between  Tripyramid  and  Osceola  there  is  a  deep  gap,  in  which  the  Greeley 
ponds  are  situated.  Osceola,  or  "  Mad  River  peak"  of  Guyot,  is  a  double 
mountain  with  a  deep  excavation  on  the  south  side  for  one  of  the  tribu 
tary  streams  of  Mad  river.  The  range  is  continuous  into  Tecumseh, 
Fisher's,  and  Welch  mountains  in  Waterville.  Sketches  of  Osceola  and 
Tecumseh  are  presented  herewith. 

Osceola  is  the  highest 
mountain  on  the  left,  in 
Fig.   28,    and  the   most 
distant  peak  on  the  right 
is  its  eastern  spur.    Mad 
river  comes  from  a  valley 
to  the    right  of  all   the 
hills  represented  in  the 
sketch.     There  is  a  deep  valley  to  the  south-west  of  Osceola.     Then  a 
mountain  appears  much  like  Osceola  reversed.     It  is  shown  in  Fig.  29,

Cone  mountain  succeeds  Welch,  but  this  is  not  so  conspicuous  an  emi 
nence  as  appears  upon  some  of  the  maps.  North-westerly  from  Osceola 
the  high  granitic  range  continues  as  far  as  the  East  Branch,  the  last  sum 
mits  being  Black  and  Loon  Pond  mountains.  This  very  interesting 
region  is  unknown  to  most  tourists.  The  only  mountain  accessible  by  a 
path  is  Osceola,  from  which  most  of  the  others  can  be  seen  to  advantage. 
7.  PassaconncrMay  Range.  This  has  an  easterly  course,  and  bounds 
the  White  Mountain  area  upon  the  south.  The  most  massive  of  the 
series  is  Black  mountain,  or  "Sandwich  Dome"  of  Guyot,  on  the  line 

between  Sandwich  and 
Waterville,  over  4,000 
feet  high.  The  annexed

to  be  stationed  near  Greeley's  hotel.  A  path  leads  to  this  summit,  where 
one  can  see  advantageously  the  Waterville  basin  as  flanked  by  Tripyra- 
mid  and  the  Osceola  range.  A  high  plateau  extends  from  Black  to 
Tripyramid  and  Whiteface.  The  latter  is  double,  and  the  southern  part 
has  been  recently  occupied  by  the  U.  S.  Coast  Survey  as  a  signal  station. 
From  here  Passaconnaway  looms  up  majestically.  It  is  a  sharp  dome, 
covered  by  trees  to  the  very  summit,  and  rises  far  above  the  surrounding

peaks.  Our  most  recent  calculations  place  this  summit  in  the  east  edge 
of  Waterville.  Passaconnaway  lies  a  little  north  of  the  main  ridge.  The 
space  between  this  and  Chocorua  is  occupied  by  low,  ragged  mountains. 

Chocorua  is  the  sharpest  of  all  the  New  Hampshire  summits,  and  can 
be  the  most  easily  recognized  and  located  on  this  account.  One  of  the 
heliotypes  gives  a  distant  view,  and  the  annexed  figure  illustrates  the 
appearance  of  the  peak  near  at  hand.  The  cone  is  composed  of  an

uncommon  variety  of  granite.  To  the  eastward  the  mountains  gradually 
fall  off  till  the  plains  of  Comvay  are  reached.  The  country  south  of  this 
mountain  range  is  low  and  undulating.

Albany  Mountains.  Swift  river  divides  the  Albany  mountains  into  two 
parts,  rising  on  the  long-  easterly  slopes  of  the  Carrigain-Osceola  range  and 
Green's  cliff.  Those  just  described  form  the  southern  rim  of  this  basin. 
Those  upon  the  north  side  are  the  Mote  mountains,  adjacent  to  Conway, 
and  mostly  unnamed  peaks  along  the  south  bank  of  the  Saco  in  Bartlett, 
joining  on  to  Tremont  in  a  wild  tract  of  forest.  The  Mote  mountains 
have  been  burnt  over,  so  that  they  appear  unusually  barren  when  seen 
from  a  distance.  They  are  the  newest  of  the  White  Mountains,  while 
the  foundations  of  the  Passaconnaway  range  are  the  oldest.  With  a 
different  arrangement  of  description,  the  Albany  basin  may  be  said  to 
have  very  gentle  slopes  upon  the  inside,  but  on  the  Saco  valley  range 
and  the  Chocorua  group  the  hills  dip  abruptly  in  opposite  directions, 
This  basin  may  also  be  termed  a  projection  eastwardly  from  the  Carri- 
gain  range. 

8.  Mts.  Lafayette  and  Twin.  This  area  is  bounded  on  the  north  by 
the  Ammonoosuc,  on  the  east  by  New  Zealand  river  and  the  east  branch 
of  the  Pemigewasset, — which  curves  so  as  to  make  it  the  south  line, 
also, — on  the  west  by  the  north  branch  of  the  Pemigewasset.  It  contains 
two  prominent  ranges, — first,  the  western  one,  from  Haystack  to  the  junc 
tion  of  the  two  branch  streams ;  and  the  other,  from  the  Twin  mountains 
to  the  mouth  of  the  Franconia  branch.  The  Haystack,  a  conical  peak,  is 
separated  by  a  series  of  small  gaps  from  Lafayette.  The  Lafayette 
mountains  are  peculiar  in  form.  The  range  is  quite  elevated,  extremely 
narrow,  and  consisting  of  seven  summits.  Lafayette,  5,290  feet,  is  the 
second  from  the  north.  Then  follow  Mt.  Lincoln  of  Fifield,  5,101  feet, 
two  nameless  peaks,  Mts.  Liberty  and  Flume,  each  4,500  feet,  the  latter 
to  the  south-east  of  the  usual  course  of  the  ridge.  This  elevated  ridge 
is  composed  of  dark  felsite.  The  peaks  south  of  Mt.  Flume  are  coarsely 
granitic,  being  Big  and  Little  Coolidge,  Potash  mountain,  and  others. 

The  Twin  mountain  range  occupies  the  middle  line  between  the  Saco 
and  Pemigewasset  rivers.  The  two  most  prominent  peaks  are  a  mile 
apart,  eight  miles  south  of  the  Twin  Mountain  house,  and  are  5,000  feet 
high.  Scarcely  any  mountains  are  more  difficult  to  reach  than  these,  on 
account  of  the  stunted  growth  near  their  tops.  The  ridge  is  broad,  and 
keeps  at  almost  the  same  level  for  two  or  three  miles  south  of  the  summit. 
On  the  west  of  this  range  there  is  an  isolated  ridge  of  no  great  dimen-

sions ;  and,  on  the  north-east,  a  mass  of  mountains  has  been  separated 
from  the  main  summits  by  the  erosive  action  of  Little  river.  The  highest 
of  these  separated  peaks  is  sometimes  confounded  with  the  Twin  moun 
tains,  because  only  one  of  the  Twins  is  seen  from  the  hotel  named  after 
them.  The  double  character  is  seen  from  either  Washington  or  Lafayette, 
and  not  from  the  Twin  Mountain  house.  That  the  early  distinctions  may 
not  be  forgotten,  and  for  the  sake  of  fixing  the  position  of  a  noble  moun 
tain,  I  venture  to  name  the  highest  of  the  unnamed  peaks  north-east  of 
Little  river  Mt.  Hale,  after  Rev.  E.  E.  Hale,  of  Boston,  editor  of  Old  and 
New,  who  assisted  Dr.  Jackson  in  exploring  the  White  Mountains,  and 
has  done  much  to  make  them  famous  by  his  writings. 

To  the  north  of  Mt.  Hale  are  three  granitic  lumps,  which,  for  conven 
ience,  I  have  called  the  Three  Sugar  Loaves.  On  the  north-east  side  of 
Twin  mountain  is  a  curious  nubble  or  small  conical  summit  150  feet  high, 
which  is  observable  from  several  places  along  the  Ammonoosuc  valley. 
It  is  probably  an  enormous  vein  of  very  coarse  granite.  Fig.  32  is  a 
rough  pen  sketch  of  the  outlines  of  the  mountains  between  Haystack 
and  the  first  Sugar  Loaf,  as  seen  from  near  the  Twin  Mountain  house. 
Their  names  are  very  plainly  indicated,  and  those  interested  will  readily 
recognize  the  place  of  the  newly  named  peak.  A  sketch  of  the  outlines 
of  the  mountains  to  the  south,  as  seen  from  the  north  Twin  mountain, 
is  given  in  Fig.  33.  This  is  a  view  very  rarely  seen;  but  the  proprietors 
of  the  Twin  Mountain  house  would  add  much  to  the  attractiveness  of 
their  establishment  if  they  would  construct  a  bridle-path  to  the  top  of 
the  mountain. 

A  view  of  the  Twin  mountains  and  Haystack,  from  the  east  part  of 
Bethlehem  hill,  Fig.  34,  will  show  better  than  words  the  several  ridges 
and  valleys  composing  the  range.  They  show  well,  also,  from  the  Wing 
Road  station,  and  from  Sugar  Hill,  Lisbon,  as  represented  in  Fig.  35. 

There  is  a  deep  and  broad  valley  between  the  Mt.  Tom  and  the  Twin 
ranges.  The  divide  between  the  New  Zealand  waters  flowing  to  the 
north,  and  of  the  East  Branch  rivulets  descending  southerly,  is  quite 
low.  It  has  all  been  excavated  by  atmospheric  agencies ; — since,  from 
geological  reasons,  it  is  clear  that  Mts.  Twin  and  Tom  were  once  con 
tinuous.

west  is  nearly  as  steep,  and  it  is  absolutely  perpendicular  a  mile  southerly. 
One  of  our  heliotypes  represents  this  valley,  closed,  apparently,  by  Eagle 
cliff. 

The  north  end  of  the  range  consists  of  a  pile  of  granite  hummocks, 
attaining  the  height  of  3,850  feet.  A  terribly  rough  valley  separates  it 
from  the  long  range  of  Mt.  Kinsman,  which  extends  to  the  extreme 
south-east  corner  of  Landaff.  It  is  ascended  from  the  village  of  Landaff, 
and  the  trip  is  easily  made.  The  relations  between  the  Profile  and 
Lafayette  range  may  be  seen  in  a  view  of  them  from  Thornton.  Lafay-

down.  The  deep  valley  of  the  Pemigewasset  lies  in  the  centre,  and  Pro 
file  on  the  left.  The  precipitous  character  of  Profile  does  not  show 
advantageously.  Only  the  lower  summit  of  this  mountain  is  generally 
visited,  the  apex  being  still  covered  by  trees.

IV.  Lake  District.  This  consists  largely  of  the  hydrographic  basin  of 
Winnipiseogee  lake,  with  sandy  plains  carrying  tributaries  of  the  Saco. 
It  is  normally  a  plain  with  four  isolated  mountain  masses  imposed  upon 
it.  These  are  the  Gunstock  and  Belknap  mountains,  Red  hill,  Ossipee 
mountains  east  of  the  lake,  and  the  Green  mountain  in  Effingham.  All 
these  mountains  are  composed  of  igneous  material,  which  seems  to  have 
been  poured  out  over  an  uneven  floor  of  rocks  deposited  in  the  Mont- 
alban  period. 

The  Belknap  range  lies  in  the  towns  of  Gilford,  Gilmanton,  and  Alton, 
on  the  south-west  side  of  Lake  Winnipiseogee,  covering  an  area  ten  by 
four  miles,  measured  along  the  greatest  diameters.  From  the  point  oppo 
site  Thompson's  island  in  Gilford  the  ridge  gradually  rises  to  the  peak 
known  as  Belknap.  This  is  directly  connected  by  a  low  saddle  with  the 
Mt.  Gunstock  of  the  Coast  Survey,  1,914  feet  high.  From  Mt.  Belknap 
a  ridge  turns  south-easterly,  and  in  the  extreme  north-east  corner  of  Gil 
manton  makes  a  curve,  so  as  to  run  a  few  degrees  north  of  east  towards 
the  lake.  This  so-called  spur  is  really  the  main  range,  and  it  continues 
on  to  Alton,  as  an  essential  prolongation  of  the  south-easterly  range  from 
Mt.  Belknap.  In  Alton,  Mts.  Straight-back,  Major,  Pine,  and  Avery  hill 
are  developments  of  this  group.  To  the  south  of  these  there  is  a  gap 
low  enough  for  a  road  from  Gilmanton  Iron  Works  to  Alton  Bay.  South 
ward  the  mountainous  area  terminates  in  the  easterly  running  hills  known 
as  Rocky  mountain.  The  principal  part  of  the  region  is  heavily  wooded, 
save  the  highest  summits,  which  are  practically  above  trees  ;  and  there 
is  uncultivated  land  enough  to  make  a  township  as  large  as  Brookline. 

Red  hill  received  from  Dr.  Timothy  Dwight  the  name  of  Mt.  Went- 
worth,  at  the  beginning  of  the  present  century.  The  mountain  area  is  of 
elliptical  shape,  with  two  summits,  the  northern*  2,043,  and  the  southern 
•1,769  feet  in  height.  The  length  is  three  miles  ;  the  breadth  about  half  as 
much.  It  lies  chiefly  in  Moultonborough,  and  partly  in  Sandwich.  Owing 
to  its  proximity  to  Center  Harbor,  Red  hill  is  much  visited  by  tourists. 

The  Ossipee  mountains  occupy  the  largest  of  all  these  mountainous 
areas,  of  oval  form,  measuring  about  six  by  ten  miles,  and  are  situated  in 
the  adjacent  corners  of  Moultonborough,  Ossipee,  Tarn  worth,  and  Tufton- 

*  Called  western  by  Guyot. 


2O4  PHYSICAL    GEOGRAPHY. 

borough.  The  broadest  portion  of  the  area  is  in  Tamworth  and  Ossipee. 
The  Bearcamp  river  washes  the  northern  base  of  the  mountains.  Two 
of  its  tributaries  have  excavated  north  and  south  valleys  out  of  the  north 
slope,  leaving  an  east  and  west  ridge  six  miles  long.  This  juts  out  from 
near  the  middle  of  the  main  range  of  about  eight  miles  length,  turning 
somewhat  easterly  in  Moultonborough  and  Tuftonborough.  The  two 
most  elevated  points,  called  for  convenience  North  and  South  Ossipee, 
lie  in  the  north-south  range.  Two  east  flowing  streams  have  excavated 
very  large  valleys  out  of  the  eastern  flank  of  these  granitic  piles,  the 
first  and  largest,  known  as  Lovell's  river,  discharging  into  Ossipee  pond, 
and  the  second,  a  tributary  of  Pine  river,  coming  out  of  Dan  Hole  pond. 
At  the  upper  end  of  Dan  Hole  pond  is  a  hamlet  known  as  Canaan. 
There  is  no  road  to  this  place  from  Moulton  mills,  up  the  valley  of  the 
outlet,  as  one  would  naturally  expect,  but  over  the  elevated  south  rim  of 
the  valley  from  Tuftonborough.  The  height  of  the  loftiest  Ossipee 
mountain  is  estimated  at  about  2,000  feet.  There  are  no  important 
streams  on  the  west  side  of  these  mountains.  The  seven  brooks  which 
course  down  the  abrupt  slope  often  produce  cascades,  but  have  not  made 
notable  excavations  in  the  edge  of  the  feldspathic  mass. 

Green  mountain  in  Effingham  is  four  miles  long,  shaped  much  like 
Red  hill,  save  that  the  two  parts  are  less  deeply  notched,  and  the  course 
is  nearly  east-west.  It  is  about  one  fourth  larger  in  every  way,  vertically 
as  well  as  horizontally. 

Except  two  ranges,  the  rest  of  the  Lake  district  is  nearly  level.  The 
first  lies  in  Eaton  and  Madison,  including  the  easterly  part  of  Free 
dom  ;  the  second  is  a  continuation  of  the  Ossipee  water-shed  through 
Wolfeborough  into  Brookfield  and  Middleton.  Also,  about  Center  Harbor 
and  Laconia  there  are  isolated  hilly  knobs. 

The  sandy  plains  of  Madison,  Freedom,  and  Ossipee  are  elevated  from 
400  to  525  feet,  extending  to  North  Conway  and  Bartlett,  in  the  moun 
tain  district.  The  average  is  nearly  that  of  Lake  Winnipiseogee.  The 
soil  is  very  sandy,  much  of  it  being  left  for  the  growth  of  small  pines. 
Between  the  Ossipee  and  the  Passaconnaway  range  the  average  eleva 
tion  of  the  land  may  be  from  550  to  600  feet,  largely  in  the  towns  of 
Tamworth  and  Sandwich.  In  Tamworth,  Chatman's,  Great,  and  McDan- 
iel's  hills  are  the  highest  points.  The  soil  is  better,  and  in  favorable

locations,  say  along  the  extensive  meadows  of  the  Bearcamp  river,  there 
are  many  large  and  profitable  farming  establishments.     An  excellent  idea 


Fig.  39. — LAKE  WINNIPISEOGEE,   FROM    CENTER   HARBOR. 


of  the  country  about  Lake  Winnipiseogee  may  be  derived  from  a  view  of 
it  given  in  Fig.  40.  The  observer  looks  from  the  east  flank  of  Sunset 
hill,  back  from  Center  Harbor  landing.  The  highest  peak  on  the  extreme 
right  is  Mt.  Gunstock ;  the  highest  on  the  extreme  left  is  the  southern 
edge  of  Ossipee  ;  those  in  the  distance  on  the  left  bound  this  district 
in  Alton,  New  Durham,  and  Middleton.  The  borders  of  the  lake  are 
usually  of  hard  pan,  sloping  gradually  to  the  water's  edge.  The  general 
course  of  the  basin  is  S.  25°  to  30°  E.,  the  islands  and  points  showing 
essentially  the  same  trend.  This  direction  is  determined  by  the  corre 
sponding  courses,  parallel  to  each  other,  of  the  Gunstock  and  Ossipee 
ranges. 

V.   The  Merrimack    Valley   District.     This    includes    more   than   the 
hydrographic  basin  on  the  west,  and  less  on  the  north.     It  is  bounded  by 


2O6  PHYSICAL    GEOGRAPHY. 

the  White  Mountains  on  the  north,  extending  as  far  as  Woodstock  in  the 
valley ;  on  the  north-east  by  the  Lake  district,  which  extends  close  to  the 
Pemigewasset  in  Ashland ;  on  the  east  by  the  coast  slope ;  slightly  on  the 
south-east  and  entirely  on  the  south  by  Massachusetts  ;  on  the  west  by 
the  Connecticut  valley  district,  or,  more  exactly,  the  eastern  boundary  of 
the  Coos  quartzite.  It  may  well  represent  the  average  physical  appear 
ance  of  New  Hampshire,  consisting  of  numerous  hills  and  mountains, 
mostly  cultivable,  interspersed  with  sandy  plains,  alluvial  flats,  and  entirely 
underlaid  by  gneissic  or  granitic  rocks.  It  is  much  the  largest  of  the 
topographical  districts.  There  are  only  two  marked  topographical  divi 
sions  of  this  tract, — the  double  mountainous  range  along  the  western 
borders,  and  the  Merrimack  valley. 

The  more  western  of  the  two  ranges  along  the  western  border  has  been 
referred  to  in  the  description  of  the  first  district.  More  particularly,  it 
may  be  said  to  follow  the  line  of  division  between  the  two  districts.  It 
commences  in  the  east  part  of  Piermont  as  Iron  and  Piermont  mountains. 
It  is  the  Cuba  mountain  range  in  Orford,  Smart's  mountain  in  Lyme, 
Moose  mountain  in  Hanover,  Grantham  and  Croydon  mountains  between 
Plainfield  and  Newport,  Perry's  mountain  between  Charlestown  and  Unity. 
It  is  wanting  in  much  of  Charlestown,  Langdon,  and  the  neighborhood 
of  Bellows  Flails.  Between  Walpole  and  Hinsdale  there  is  a  series  of 
hills,  mostly  unnamed,  which  mark  the  line,  though  some  of  them  are 
covered  by  slate. 

From  Warren  to  Plymouth,  Baker's  river  has  cut  through  the  range 
transversely.  Webster  Slide  and  Mist  mountains  are  continuous  with 
Iron  mountain.  The  valley  between  the  two  ranges  commences  east  of 
Piermont  mountain,  bordered  easterly  by  Ore  hill,  Warren,  the  water 
flowing  northerly.  In  the  same  depression  Pond  brook  rises,  flowing  to 
the  south-east  to  join  Baker's  river.  Other  tributaries  flow  in  the  same 
direction  in  Wentworth.  The  depression  is  again  markedly  manifest  in 
Dorchester,  having  Smart's  mountain  range  on  the  west,  and  the  Groton 
hills  on  the  east.  It  is  more  pronounced  still  in  Canaan,  Enfield,  and  the 
east  part  of  Hanover.  The  quartz  range  is  broken  first  in  Lyme,  and 
more  markedly  by  the  outlet  of  Mascomy  lake  in  East  Lebanon.  The 
lowland  water-shed  between  the  Mascomy  and  Sugar  rivers  lies  in  the 
swampy  district  near  the  south  line  of  Enfield.  The  Croydon  range 


TOPOGRAPHY.  2O/ 

borders  the  valley  to  Claremont,  where  the  erosion  is  more  observable 
than  at  East  Lebanon,  allowing  Sugar  river  to  pass  into  Claremont.  This 
river  is  further  remarkable,  since  it  cuts  the  main  range,  also  draining  a 
large  area  east  of  Sunapee,  which  would  more  naturally  flow  into  the 
Merrimack. 

From  Newport  the  valley  between  the  parallel  ranges  passes  more 
easterly  into  Goshen  and  Lempster,  rising  in  the  swamps  near  Dodge 
pond,  the  source  of  the  tributaries  of  Cold  river,  which  courses  southerly 
through  Acworth,  Langdon,  and  the  corners  of  Alstead  and  Walpole. 
North  Unity  and  North  Acworth  possess  water-sheds  parallel  to  each 
other  and  running  easterly,  having  Little  Sugar  river  between  them. 
There  are  no  notable  hills  on  either  side,  though  the  land  is  high.  This 
irregularity  is  induced  by  the  rising  up  of  older  earth-masses  in  Kilburn 
Peak,  near  Bellows  Falls. 

The  valley  is  next  continuous  in  the  Ashuelot  basin.  The  north  rim 
lies  between  Paper  Mill  Village  and  Alstead  Centre.  The  ridge  in  Mar- 
low,  where  the  old  and  new  Forest  roads  unite,  is  1,328  feet  high,  along 
the  line  of  a  railroad  survey.  Just  north  of  the  Ashuelot  valley,  near 
Alstead  village,  the  ridge  is  lower,  estimated  to  be  about  900  feet.  In 
Surry  the  valley  is  narrow  and  deep.  In  Keene  it  spreads  out  widely, 
the  level  at  the  railroad  being  482  feet.  It  narrows  in  passing  into 
Swanzey,  but  is  constantly  deepening.  At  Winchester  the  river  turns 
into  Hinsdale,  across  a  very  ancient  ridge ;  but  the  valley  continues  into 
Massachusetts  in  a  direct  southerly  course. 

Principal  Range.  The  main  water-shed  of  the  state  is  the  eastern 
part  of  this  double  range.  Leaving  the  White  Mountain  district  in 
Moosilauke,  it  starts  up  again  in  the  high  Kinneo  and  Carr's  mountains, 
running  down  through  Wentworth  and  Rumney,  ending  in  Rattlesnake 
mountain,  till  cut  across  by  Baker's  river. 

Warren  occupies  an  elevated  position  between  the  two  great  ranges. 
The  general  shape  of  the  land  is  that  of  a  basin,  with  notched  edges. 
Just  to  the  north  the  immense  mass  of  Moosilauke  makes  a  third  side  to 
the  depression,  while  the  narrowness  of  the  Owl's  Head  pass  nearly 
closes  up  the  valley  on  the  north-west.  The  map  of  Warren  annexed, — 
kindly  loaned  by  William  Little,  of  Manchester,  an  early  friend  of  the 
survey,  and  author  of  a  history  of  Warren, — shows  better  than  words  the

topographical  features  of  the  town,  with  its  ancient  and  modern  artificial 
limits. 


Fig.   40. — MAP   OF  WARREN. 

Our  main  range  rapidly  recovers  itself  in  the  highlands  of  Groton,  and 
Mt.  Cardigan  in  Orange.  The  next  low  point  is  at  the  summit  of  the 
Northern  Railroad.  Next,  we  find,  in  Grafton,  Isinglass  mountain  and 
Prescott  hill.  In  Springfield  the  range  is  continuous  in  Aaron's  ledges, 
Shad,  Stevens's,  Col.  Sanborn,  Hoyt,  Sanborn,  and  Hog  hills,  besides 
others  not  mentioned  on  the  map.  The  continuity  is  interrupted  by  the 
basin  of  Sunapee  lake.  Directly  to  the  south  are  the  Sunapee  moun 
tains,  along  the  line  between  Newbury  and  Goshen.  These  connect 
directly  with  Kittredge,  Jones,  Taylor,  and  Ames  hills,  and  Mt.  Lovell  in 
Washington.  At  the  village  the  range  is  cut  through  by  streams  flowing 
south-easterly;  but  the  ridge  is  continuous  from  Oak  hill  to  Stoddard, 
the  west  part  of  Nelson,  and  so  on  to  Mt.  Monadnock. 


TOPOGRAPHY.  2<X) 

Mt.  Monadnock  is  usually  described  as  an  isolated  peak  rising  out  of  a 
plateau,  having  the  altitude  of  3,186  feet;  while  the  plain  will  average 
from  1,000  to  1,200  feet,  including  the  towns  of  Jaffrey,  Sharon,  Fitzwil- 
liam,  New  Ipswich,  and  others.  While  this  is  generally  correct,  it  should 
be  modified  so  that  it  be  understood  to  be  part  of  the  principal  backbone 
of  the  state,  and  the  culminating  peak  of  the  southern  part  of  the  range. 
There  are  geological  reasons  for  explaining  its  isolated  position,  which 
will  be  mentioned  hereafter.  The  Pack  Monadnock  range  is  really  a  part 
of  the  Monadnock  group.  The  Contoocook  river,  with  its  Harrisville 
branch,  has  excavated  a  deep  channel  through  the  Monadnock  plateau, 
sinking  northerly.  Consequently  there  are  left  high  hills  to  the  west,  as 
in  Nelson  and  Hancock,  Bald,  Willard,  and  Robb  mountains  in  Antrim, 
etc.  On  the  east  is  the  more  important  range  of  hills  in  the  west  part 
of  Deering,  Crotchet  mountain  in  Francestown,  Pinnacle  mountain  in 
Lyndeborough,  Pack  Monadnock  in  Peterborough  and  Temple,  Temple, 
Kiclder,  and  Barrett's  mountains  in  Temple  and  New  Ipswich.  This  is 
now  the  main  range,  having  come  from  a  direction  east  of  north  to  join 
the  Monadnock  water-shed.  It  continues  southerly  into  Massachusetts, 
viz.,  Watatic  mountain  in  Ashburnham,  Wachusett,  2,018  feet,  in  Prince 
ton  ;  and  so  on  southerly  through  the  central  part  of  the  state.  The 
White  Mountain  range,  therefore,  when  correctly  followed,  does  not 
pass  into  the  Connecticut  valley  Trap  mountains,  as  maintained  by  some 
authors. 

Heights  along-  the  Principal  Water-shed  of  New  HampsJiirc.  The 
main  water-shed  of  New  Hampshire  runs  nearly  parallel  to  Connecticut 
river,  and  in  fact  forms  the  eastern  rim  of  that  hydrographic  basin. 
It  is  of  special  importance  to  one  studying  the  topography  of  the  state, 
and  for  that  reason  is  given  here  as  fully  as  possible. 

From  near  the  north  corner  of  the  state  to  Mt  Washington,  this  line 
skirts  the  Androscoggin  basin.  It  borders  the  Saco  waters  only  from 
Mt.  Washington  to  Mt.  Field.  From  here  to  Massachusetts  the  line 
agrees  with  the  west  border  of  the  Merrimack  system.  The  line  may  be 
divided  into  three  sections  :  First,  averaging  2,000  feet  elevation  to  the 
base  of  Mt.  Madison.  Second,  the  White  Mountain  division  from  Madi 
son  to  Moosilauke,  averaging  nearly  4,000  feet.  Third,  the  portion  from 
Warren  to  Massachusetts,  averaging  about  1,500  feet.  The  lowest  point

in  the  northern  section  is  at  the  Milan  summit  on  the  Grand  Trunk  Rail 
way,  1,087  feet-  The  lowest  point  in  the  White  Mountain  line  is  at  the 
notch,  1,914  feet.  The  Franconia  notch  is  nearly  the  same,  being  2,014 
feet.  The  lowest  point  in  the  entire  line  is  at  the  Orange  summit  of  the 
Northern  Railroad,  990  feet.  The  next  lowest  point  is  at  Warren,  1,063 
feet.  It  is  followed  by  the  railroad  cut  at  Milan,  1,087,  and  at  Newbury, 
1,161  feet,  for  the  natural  surface  of  the  ground.  Two  projected  railway 
lines  cross  the  southern  section,  with  the  height  of  1,560  feet  in  Stod- 
dard,  and  of  1,265  at  Harrisville.

Other  Elevated  Areas.  There  are  several  important  hilly  areas  in  the 
Merrimack  basin,  immediately  adjoining  the  range  just  described.  The 
first  is  a  hilly  area  in  New  Hampton  and  Sanbornton,  consisting  of 
Burleigh,  Hersey,  and  Sanbornton  mountains  on  the  east  side  of  the 
Pemigewasset.  Next  are  the  Ragged  mountains  of  Andover  and  Hill. 
Separated  from  these  by  the  Blackwater  river  are  the  Kearsarge  moun 
tains  in  Warner,  Wilmot,  and  Salisbury,  the  most  important  of  all  the 
groups.  Kearsarge  resembles  Monadnock  in  form,  general  features,  and 
geological  structure.  Smaller  areas  worthy  of  notice  are  the  dying  out 
of  the  Ragged  mountain  range,  with  a  southerly  instead  of  easterly  trend, 
in  Franklin  and  Boscawen  ;  the  Sutton  hills,  perhaps  a  continuation  of 
Kearsarge  ;  an  unnamed  area  in  Bradford  and  Hillsborough,  Mink  hills  in 
Warner,  Craney  hill  in  Henniker,  with  eminences  in  North  Weare ;  the 
Dunbarton  heights,  the  Uncanoonucs  of  Goffstown,  Joe  English  hill  in 


212  PHYSICAL    GEOGRAPHY. 

New  Boston,  Lyndcborough  mountains,  the  hilly  area  of  south-west 
Lyndeborough  and  Mt.  Wilton,  and  the  Rattlesnake  hill  granitic  range  of 
Concord.  Perhaps  the  hilly  character  of  Mt.  Vernon,  Amherst,  Mason, 
and  other  localities  may  be  worthy  of  notice. 

On  the  east  side  of  the  Merrimack  are  several  hilly  groups,  as  Bean 
hill,  Northfield,  spreading  into  Canterbury  on  the  south  and  into  Gilman- 
ton  on  the  east;  the  somewhat  isolated  peaks  of  Grant,  Bradford,  and 
Cogswell  hills,  in  the  east  part  of  Gilmanton ;  scattered  summits  in  south 
west  Gilmanton  and  eastern  London,  Catamount  mountains  in  Pittsfield, 
Brush  hill,  McKoy's  Fort,  and  Nottingham  mountains  in  Epsom,  with 
high  land  in  the  west  part  of  Deerfield.  Farther  south  the  elevations 
are  of  less  consequence.  There  is  high  land  in  Allenstown,  extending  in 
a  range  to  Hooksett,  and  terminating  in  Campbell's  hill  near  the  Merri 
mack.  There  are  minor  ridges  following  the  course  of  the  two  bands  of 
quartzite,  referred  to  on  p.  50.  The  Manchester  ridge  runs  a  little  east 
of  north  into  the  west  part  of  Auburn  and  Candia,  connecting  with  the 
abandoned  railroad  summit  at  Rowe's  Corner,  and  the  Allenstown  range 
beyond.  We  can  also  trace  an  important  ridge  from  Candia  through 
Auburn,  Chester,  Derry  East,  and  Windham,  lying  between  Corbett's 
and  Policy  ponds  just  before  entering  Massachusetts. 

TJic  Loivland  Country.  There  are  no  swamps  nor  low  meadows  of  any 
consequence  anywhere  along  the  Merrimack  river.  The  clay  banks, 
when  present,  are  usually  high  up,  covered  by  sand.  The  high  sandy 
plains  commence  in  New  Hampton.  Here  they  are  undulating  and  nar 
row.  At  Bristol  they  are  cut  off,  and  there  is  no  correctness  in  Dr. 
Jackson's  map,  representing  the  great  bend  opposite  Bristol  as  composed 
of  drift.  They  skirt  both  sides  of  the  river  in  Sanbornton,  Tilton,  Hill, 
and  Franklin.  In  Northfield,  Canterbury,  Boscawen,  and  Concord  we 
find  the  most  extensive  development  of  the  elevated  sandy  plains.  In 
the  east  part  of  Concord  the  plain  is  about  one  hundred  and  twenty-five 
feet  above  the  river,  and  two  miles  wide.  The  plains  are  contracted  to  a 
line  at  Hooksett,  widening  in  the  south  part  of  the  town.  The  Piscata- 
quog  river  develops  this  sandy  plain  several  miles  back  into  Bedford  and 
Goffstown,  from  Manchester.  Litchfiekl  is  chiefly  a  sandy  plain.  Merri 
mack,  Amherst,  Nashua,  and  Hudson  possess  large  areas  of  the  same, 
but  the  land  so  far  down  the  river  is  everywhere  low,  and  is  mostly 


• 


TOPOGRAPHY.  2  I  3 

covered  by  hard  pan,  which  has  somewhat  of  a  sandy  character,  and  ought 
not  to  be  confounded  with  the  elevated  plain  above,  for  geological  reasons. 
Every  large  tributary  below  Manchester,  as  the  Souhegan  and  Nashua 
rivers,  enlarges  the  bounds  of  the  lowland,  causing  it  to  wind  back  among 
the  border  hills  for  many  miles. 

The  valley  of  the  Merrimack  below  Nashua  in  Massachusetts,  in  gen 
eral  terms,  may  be  said  to  agree  exactly  with  its  physical  features  in  New 
Hampshire  below  Manchester. 

VI.  Coast  Slope.  This  greatly  resembles  the  lower  Merrimack  country. 
It  starts  from  the  mountainous  ridge  bordering  the  Lake  district  on  the 
south,  and  is  bounded  westerly  by  the  Merrimack  river  basin.  The 
northerly  boundary  consists  of  the  following  eminences,  running  in  an 
easterly  direction:  Mt.  Bet,  Mt.  Holly,  Cropple  Crown  mountain,  and 
Birch  hill,  with  the  Rattlesnake  mountains  for  foot  hills  in  New  Durham  ; 
the  Great  Moose,  Bald,  Hall,  and  Parker's  mountains  in  Middleton.  The 
range  is  cut  through  by  Fellows's  branch  of  the  Salmon  Falls  river  in 
Wakefield  (Union  Village);  and  the  hills  to  the  east,  in  Milton,  are  4ow. 

In  general,  it  may  be  stated  that  the  entire  northerly  and  westerly  bor 
ders  of  this  district,  as  represented  upon  the  map,  are  the  lines  of  highest 
elevation,  or  the  rim-edge  of  a  basin,  which  slopes  gently  towards  the 
ocean,  having  miscellaneous  ridges  and  isolated  peaks  scattered  at  ran 
dom  over  its  surface.  The  first  subdivision  of  this  basin  is  a  triangular 
area,  widest  at  the  north,  with  a  very  prolonged  and  swelling  apex.  It  is 
situated  between  the  Cochecho  and  Salmon  Falls  rivers,  comprising  New 
Durham,  Middleton,  Milton,  parts  of  Wakefield,  Farmington,  Rochester, 
Dover,  and  the  whole  of  the  small  towns  of  Somersworth  and  Rollins- 
ford.  Milton  seems  to  have  a  culmination  in  Teneriffe  mountain,  near 
its  topographical  centre.  Middleton  and  New  Durham  slope  uniformly 
towards  the  two  rivers,  with  lateral  north-south  ridges  between  tributary 
streams.  The  Rochester  portion  is  a  perfectly  flat,  sandy,  swampy  plain, 
226  feet  above  the  sea.  In  the  laterally  expanded  apex  of  the  triangle, 
there  is  a  long  elevation  midway  between  the  rivers,  ending  with  Garrison 
hill  in  Dover. 

A  second  subdivision  may  embrace  the  easterly  flowing  waters  of  the 
Cochecho.  This  includes  the  south-easterly,  bearing  "  New  Durham  ridge" 
in  the  south  corner  of  the  town;  the  more  extensive  north  east-south 


214  PHYSICAL    GEOGRAPHY. 

west  range  of  the  Blue  Job  mountain  in  Farmington,  and  the  Blue  hills 
of  Strafford ;  a  north  west-south  east  ridge,  at  right  angles  to  the  last, 
from  Chesley  mountain,  in  Farmington,  to  the  west  part  of  Rochester; 
and  the  extensive  basin  of  Isinglass  river,  fed  by  Round,  Long,  Nippo, 
Stonehouse,  and  Ayer's  ponds,  in  Barrington. 

A  third  subdivision  may  be  represented  by  the  Lamprey  river  basin, 
including  most  of  Northwood,  Nottingham,  Deerfield,  and  the  vicinity  of 
the  Concord  &  Portsmouth  Railroad.  The  first  three  towns  mentioned 
show  mountainous  areas,  as  the  Saddleback  in  the  south  part  of  North- 
wood,  and  the  double  group  of  Pawtuccawa  in  the  west  part  of  Notting 
ham,  edging  into  Deerfield.  In  the  east  part  of  Nottingham  there  is  a 
large  marshy  country  tributary  to  Pawtuccawa  pond.  There  is  nothing 
of  much  importance  in  the  rest  of  the  Lamprey  valley. 

The  fourth  subdivision  may  be  termed  the  Exeter  river  basin.  This 
crooked  stream  rises  in  Chester,  and  flows  through  parts  of  Raymond 
and  Fremont,  where  it  is  joined  by  another  branch  through  Sandown,  start 
ing  in  Chester,  thence  through  Brentwood  and  Exeter,  joining  Great  bay 
between  Newmarket  and  Stratham.  After  viewing  the  hills  of  Farming- 
ton  and  Middleton,  there  is  nothing  in  this  subdivision  worthy  of  note. 

The  balance  of  this  coast  district  may  be  called  the  Hampton  division, 
embracing,  perhaps,  the  most  square  miles  of  territory  possessed  by  any 
of  the  five  areas.  It  embraces  three  fourths  of  the  land  eastward  from 
the  Boston  &  Maine  Railroad.  The  land  is  low,  but  not  marshy,  except 
along  the  shore  line  in  Seabrook,  Hampton  Falls,  and  Hampton.  The 
northern  portion  is  a  promontory  between  the  Great  bay  and  the  Atlantic 
ocean.  There  is  an  extensive  sea  beach  on  it  in  Rye,  with  ledges  on  the 
coast  at  Little  Boar's  Head,  Frost's  Point,  and  Newcastle. 

There  is  a  peculiar  class  of  drift  hills  observed  in  this  area  that  do  not 
occur  far  back  from  the  ocean.  They  may  be  from  eighty  to  two  hundred 
feet  above  the  adjoining  lowland.  They  may  be  termed  bowl-shaped  or 
elongated  ridges,  according  to  circumstances.  I  have  searched  in  vain 
for  ledges  about  them,  and  have  therefore  concluded  that  they  are  entirely 
composed  of  drift  brought  from  the  north.  I  have  reason  to  believe 
many  of  them  exist  in  Rockingham  county,  a  field  that  yet  remains  to  be 
fully  explored.  Signal  examples  are  in  Stratham,  in  the  north  middle  dis 
trict,  prominent  on  the  map  by  reason  of  the  absence  of  roads  over  it,

and  in  South  Hampton  abundantly.  Great  Boar's  Head,  in  Hampton, 
is  another  example.  Others  occur  in  Massachusetts,  as  Prospect  hill, 
Andover. 

The  Isles  of  Shoals  belong  to  the  coast  slope,  being  remnants  of  land 
that  may  formerly  have  been  connected  with  the  main  land.  As  they  are 
little  elevated  above  the  tide,  most  of  the  loose  materials  have  been 
washed  away  by  the  severe  north-east  storms  occurring  off  our  coast.  I 
found  on  Star  island  boulders  that  had  been,  derived  from  the  main  land 
thirty  or  forty  miles  distant.

CHAPTER    VIII. 


TOPOGRAPHY    OF    COOS    COUNTY 


BY   J.    H.    HUNTINGTON. 


>HE  extreme  northern  part  of  New  Hampshire  is  covered  by  a  con 
tinuous  primeval  forest ;  and  the  surface  of  the  country  is  broken 
by  undulating  ridges,  which  here  and  there  rise  to  mountain  heights.  In 
these  forests,  almost  on  the  boundary  of  Quebec  province,  is  the  source 
of  the  Connecticut  river;  and  in  the  extreme  north-east  corner  of  the 
state  is  a  small  lake,  which  is  the  principal  source  of  the  Magalloway 
river.  Scarcely  anything  more  is  known  to  the  dwellers  on  the  banks  of 
the  Connecticut  as  to  its  source,  than  they  know  of  the  source  of  the 
Nile.  Hence  we  shall  give  a  somewhat  minute  description  of  this 
section. 

The  difficulties  encountered  in  traversing  an  unbroken  forest  are  many 
and  varied.  At  times  the  experience  is  most  pleasurable,  and,  again, 
obstacles  are  encountered  that  are  almost  insurmountable.  To-day  we 
cross  a  beautiful  lake.  The  clear,  sparkling  waters  reflect  the  bright  sun 
light,  while  along  its  borders  are  mirrored  the  trees  that  stand  in  stately 
grandeur  on  its  shores.  To-morrow  its  waters  roll  in  tumultuous 
wave,  and  the  clouds  rest  almost  on  the  bosom  of  the  lake.  To-day  we 
traverse  its  shores,  and  walk  upon  the  soft  green  moss  that  lies  spread 
under  the  trees  of  evergreen  like  a  carpet,  so  soft  and  elastic  to  the 


TOPOGRAPHY    OF    COOS    COUNTY.  2 1/ 

tread,  while  the  rays  of  the  sun,  shining  through  the  thick  foliage,  give 
a  Denial  liorht,  and  the  fresh  green  moss  coxrers  even  the  fallen  trunks  of 

O          '  O  '  O 

the  trees,  as  if  to  conceal  every  sign  of  decay ; — and  here,  where  a  stream 
trickles  over  its  mossy  bed,  one  is  carried  away  in  elysian  dreams,  and 
forgets  all  else  save  that  some  enchantment  binds  him  here.  But  to-mor 
row  we  become  entangled  in  the  undergrowth  and  shrubs,  in  what  seems 
to  be  an  illimitable  morass ;  while  the  gently  descending  rain  adheres  to 
every  spray  of  the  foliage,  and  every  touch  brings  down  an  additional 
shower  to  add  to  our  discomfiture,  until  every  thread  of  our  apparel  is 
saturated.  As  we  struggle  on  through  the  underbrush  and  tangled 
ferns,  we  become  bewildered  as  to  our  course,  and  our  compass  shows  us 
that  we  are  travelling  in  a  direction  exactly  opposite  to  that  we  wished  to 
go ;  and  we  conclude  that  this  is  certainly  studying  geology  under  difficul 
ties.  To-day  we  traverse  a  section  where  not  a  single  rock  is  to  be  seen 
in  place :  to-morrow  ledges  that  excite  the  liveliest  interest  crop  out  on 
every  hillside.  To-day  the  vision  is  circumscribed  within  the  narrowest 
limits:  to-morrow  we  ascend  some  lofty  mountain,  where  the  view  is 
unobstructed,  and  where  the  undulations  of  the  forests,  as  they  stretch 
out  in  the  far  distance,  seem  like  vast  waves  of  the  ocean ;  and  nothing 
is  more  pleasing  than  to  watch  the  shadows  of  the  fleeting  clouds  as  they 
pass  over  these  miles  of  forests.  To-day  we  see  only  the  straight  shafts 
of  the  spruce  and  fir:  to-morrow  the  trees  are  varied,  and  along  our 
pathway  are  plants  of  rare  beauty, — orchids, — that  would  attract  the 
attention  of  the  most  careless  observer.  To-day  we  see  no  sign  of 
animal  life,  and  the  songs  of  birds,  even,  break  not  the  stillness  of  these 
deep  solitudes :  to-morrow  we  may  be  carried  away  in  ecstacies  of  delight 
as  the  song  of  the  hermit  thrush  greets  the  ear,  or  we  wonder  at  the 
extraordinary  volume  of  song  that  the  little  winter  wren  pours  forth ;  and, 
as-  we  see  its  diminutive  size,  we  mark  the  force  of  the  comparison  of 
the  Indian  who  said  that,  if  he  had  strength  in  proportion  as  this  bird  has 
power  of  song,  he  could  move  the  world ; — and  it  would  not  be  strange  if, 
in  our  travels  through  the  woods,  we  should  meet  a  deer  or  see  a  moose. 
To-day  the  cool  breezes  drive  every  insect  from  the  air:  to-morrow,  in 
the  dense  forests,  the  mosquitoes  are  in  perfect  swarms,  and  their  attacks 
drive  one  almost  frantic.  In  the  openings,  where  the  mosquitoes  cannot 
endure  the  sun,  the  black  flies  are  sure  not  to  be  wanting.  The  very  air 
VOL.  i.  30 


2l8  PHYSICAL    GEOGRAPHY. 

seems  filled  with  them,  and  their  attacks  are,  if  possible,  more  persistent 
than  those  of  the  mosquitoes ;  and  we  are  bled  at  every  pore,  so  that  the 
face  becomes  one  mass  of  gore.  To-night,  after  a  delightful  clay,  we 
camp  beneath  the  clear  blue  sky,  while  the  shimmering  light  of  the  moon 
through  the  trees  gives  a  dreamy  aspect  to  the  scene ;  and,  reclining  on 
our  elastic  bed  of  boughs  of  fir,  we  need  no  somnific  portion  to  bring  sleep 
and  repose.  But  again,  another  night,  thoroughly  saturated,  we  seek 
a  camping-place,  while  the  rain  still  pours  in  torrents.  Stretching  our 
shelter-tent,  we  kindle  a  fire  with  the  bark  of  the  birch  trees,  and,  in  the 
drenching  rain,  cut  wood  for  our  camp-fire.  Then,  retiring  within  our 
shelter,  we  steam  until  we  are  dry.  So,  day  by  day,  the  experience  is 
ever  new ;  but  at  no  time  is  it  an  easy  task  to  travel  through  the  unbroken 
forests. 

WATER-SHEDS. 

Along  the  water-shed  that  separates  the  head  waters  of  the  Connecti 
cut  and  Magalloway  from  those  of  the  St.  Lawrence,  runs  the  boundary 
line  between  New  Hampshire  and  Quebec  province.  Although  its  gen 
eral  direction  from  Crown  monument  to  the  head  of  Hall's  stream  is  a 
little  south  of  west,  yet  so  crooked  is  it  that  in  its  course  it  runs  towards 
nearly  every  point  of  compass,  making  the  distance  nearly  twice  as  great 
as  it  is  in  a  direct  line  between  these  points. 

At  Crown  monument  the  height  of  the  water-shed  is  2,568  feet.  It 
descends  gently  for  a  short  distance  as  we  go  west,  but  soon  rises  again, 
until,  near  Lake  Magalloway,  it  has  an  elevation  of  2,812  feet.  The  sum 
mit  of  the  ridge  here  is  587  feet  above  the  lake  just  mentioned.  Then 
north-west  of  the  lake  there  is  quite  a  gap,  but  it  soon  rises  again  into  a 
mountain  ridge.  But  two  miles  west  of  the  lake  is  another  depression : 
in  this  rises  the  most  north-westerly  branch  of  the  Magalloway.  West  of 
this  the  ridge  rises  again,  and  forms  a  mountain  range  which  extends 
west  two  miles  to  the  gap  near  Third  lake.  Extending  south  from  this 
height  of  land  is  the  water-shed  between  the  Connecticut  and  Magallo 
way.  The  gap  at  Third  lake  has  a  height  of  2,146  feet.  Then  there  is 
a  slight  rise,  and  again  a  depression  of  about  the  same  height  as  the  last. 
Then  the  water-shed  rises  again  to  the  summit  of  Mt.  Prospect,  to  an 
elevation  of  2,629  feet.  It  then  descends,  but  continues  with  varying 


TOPOGRAPHY  OF  COOS  COUNTY.  2IQ 

undulations,  until,  near  the  head  of  Hall's  stream,  it  spreads  out  into  an 
immense  plateau. 

The  water-shed  that  separates  the  waters  of  the  Connecticut  from  the 
Magalloway,  Androscoggin,  and  Saco  rivers,  runs  as  follows :  Starting 
from  the  boundary  of  Quebec  province,  five  miles  south-west  of  Crown 
monument,  and  not  far  from  three  miles  east  of  Third  lake,  the  line 
runs  nearly  south  four  miles  ;  then  it  turns  almost  directly  east,  and 
extends  to  Mt.  Kent,  on  the  boundary  between  New  Hampshire  and 
Maine  ;  thence  it  follows  the  boundary  to  Mt.  Carmel ;  thence  it  runs 
a  little  south  of  west,  to  a  point  two  miles  south  of  Second  lake; 
thence  south  to  Magalloway  mountain;  thence  it  follows  a  ridge  west 
nearly  a  mile ;  thence  it  runs  south-west  to  Mt.  Pisgah ;  then  it  bends 
still  to  the  west,  and  reaches  its  western  limit  near  the  Diamond  ponds 
in  the  eastern  part  of  Stewartstown ;  thence  it  runs  south-east  to 
Dixville  notch  ;  thence  a  little  east  of  south,  through  the  western  part 
of  Millsfield ;  thence  south  through  Milan,  Berlin,  and  Randolph ;  thence 
over  the  White  Mountains  to  the  notch.  Along  this  water-shed  is 
some  of  the  highest  land  in  New  Hampshire ;  but  there  are  occasional 
gaps  where  roads  are  or  can  be  constructed.  Some  of  these  passes 
are  well  known.  Going  north  from  the  notch,  the  first  is  in  Ran 
dolph  ;  the  next  is  where  the  Grand  Trunk  Railway  passes ;  then  there 
is  the  road  through  Dixville  notch ;  but  north  of  this  no  carriage-road 
has  ever  been  constructed, — and  there  are  only  three  winter  roads, 
and  these  for  lumbering  purposes.  The  first  of  these  roads  crosses  the 
Connecticut  three  and  a  half  miles  south  of  Connecticut  lake,  and  runs 
south-east.  After  passing  the  height  of  land,  it  strikes  one  of  the  branches 
of  the  Swift  Diamond,  and,  following  this,  it  extends  down  to  the  Magal 
loway.  The  second  road  begins  at  the  last  settlement  in  Pittsburg, 
crosses  the  Connecticut  one  mile  north  of  Connecticut  lake,  and  strikes 
the  Magalloway  four  miles  south  of  Parmachena  lake.  It  is  several  years 
since  either  of  these  roads  was  used,  but  through  the  evergreen  forests 
they  are  as  distinct  as  when  first  made, — yet  through  the  deciduous  trees 
the  underbrush  has  so  obstructed  the  way  that  it  is  almost  impossible  to 
pass,  even  on  foot.  Along  either  of  these  routes  there  is  nothing 
to  hinder  the  construction  of  a  carriage-road,  and,  probably  along  the 
most  northern,  one  will  never  be  called  for ;  but  it  may  be  opened  again 


22O  PHYSICAL    GEOGRAPHY. 

as  a  "tote"  road  when  lumbering  is  carried  on  along  the  Upper  Magallo- 
Avay.  The  third,  a  new  tote  road,  recently  opened  to  the  Magalloway 
by  the  way  of  Second  lake,  will  probably  be  the  one  that  will  be  most 
used,  since  it  strikes  farther  up  the  river.  The  water-shed  itself,  and 
the  country  east,  is  broken  up  into  irregular  groups  of  mountains  and 
hills,  but  no  two  groups  have  exactly  the  same  kind  of  rocks.  The  axis 
of  all  the  higher  groups  is  either  gneiss  or  schist. 

The  northern  portion  of  the  area  of  Vermont,  that  is  represented  on 
the  topographical  map,  is  covered  for  the  most  part  with  forests.  In 
general,  the  features  of  the  country  are  very  irregular,  and  in  the  more 
rugged  portions  the  land  rises  to  mountain  heights.  On  the  east,  Mt. 
Monadnock,  in  Lemington,  is  not  far  from  3,000  feet  above  the  valley  of 
the  Connecticut,  while  in  the  towns  immediately  south  of  the  Grand 
Trunk  Railway  there  are  half  a  score  of  mountain  peaks.  From  this 
last  area  streams  flow  in  every  direction, — north  into  the  Nulhegan,  east 
into  the  Connecticut,  and  south  and  east  into  the  Passumpsic. 

The  water-shed  between  the  Connecticut  and  the  St.  Lawrence  runs 
south-west  from  the  head  of  Hall's  stream  through  the  township  of 
Auckland,  and  when  it  strikes  Hereford  it  runs  nearly  west  almost  to  the 
limit  of  the  township  ;  thence  it  runs  directly  south  about  four  miles, 
when  it  turns  westerly  into  Barford ;  and  thence  it  runs  southward,  and 
enters  Vermont  in  the  extreme  west  part  of  Canaan.  It  then  runs  south 
between  Great  Averill  and  Little  Leach  ponds.  Between  these  the 
height  of  land  is  probably  not  more  than  fifty  feet.  From  Great  Averill 
pond  it  runs  south  perhaps  a  mile  and  a  half  below  Little  Averill,  thence 
westward,  bending  northward  around  the  head  of  the  north  branch  of  the 
Nulhegan,  and  strikes  the  Grand  Trunk  Railway  in  Warren  Gore,  when 
it  turns  abruptly  southward  and  eastward,  and  strikes  the  Grand  Trunk 
Railway  again  two  miles  south-east  of  Island  Pond  village.  Southward 
the  road  from  Island  Pond  to  Burke  crosses  the  water-shed  near  the 
southern  line  of  Brighton ;  from  thence  it  has  generally  a  westerly  trend, 
and  the  Passumpsic  railroad  crosses  it  in  the  north-west  part  of  Sutton, 
when  it  passes  out  of  the  limit  of  our  map.  The  great  irregularity  of 
surface  in  this  north-east  section  of  Vermont  is  due  principally  to  the 
great  difference  in  the  character  of  the  rocks.  There  are  few  areas  of 
equal  extent  where  so  great  a  variety  of  crystalline  rocks  are  found. 


TOPOGRAPHY  OF  COOS  COUNTY.  221 

THE  WATER  BASINS. 

The  northern  portion  of  the  water  basin  of  the  Connecticutt,  he  Magal- 
loway,  the  Androscoggin,  and  the  Saco,  is  embraced  in  this  section. 
North  of  latitude  45°  it  embraces  nearly  the  whole  of  that  of  the  Con 
necticut.  West  of  the  Connecticut  river,  and  north  of  latitude  45°,  there 
are  three  nearly  parallel  ridges.  The  first,  going  west,  is  somewhat  irreg 
ular,  and  is  cut  off  where  Perry's  stream  turns  east  and  flows  into  the 
Connecticut.  But  two, — one  between  Perry's  and  Indian  streams,  and 
the  other  between  Indian  and  Hall's  streams, — are  more  uniform,  and 
they  have  a  mean  height  of  about  six  hundred  feet  above  the  streams. 
South  of  latitude  45°,  and  east  of  the  Connecticut,  the  ridges  are  every 
where  very  irregular.  North  hill,  in  Clarksville,  rises  1,971  feet  where 
the  road  crosses.  South  hill,  in  Stewartstown,  is  2,000  feet,  ascending  to 
Jackson.  In  Colebrook  and  below,  the  high  ridges  branching  from  the 
water-shed  have  generally  a  westerly  trend.  South  of  Sims  stream  the 
ridge  extends  nearly  to  the  Connecticut,  as,  also,  the  one  in  Stratford, 
south  of  Lyman  brook.  Below  North  Stratford  the  ridges  run  more  to 
the  south.  In  Northumberland,  south  of  the  Upper  Ammonoosuc,  they 
again  run  more  nearly  west,  and  continue  thus  until  we  reach  Dalton, 
where  the  principal  ridge  runs  north  and  south. 

Seven  miles  south  of  Crown  monument  the  water-shed  touches  the 
boundary  line  of  Maine.  The  portion  of  the  water  basin  of  the  Magallo- 
way  north  of  this  is  a  level  tract  of  country,  penetrated  by  spurs  from 
the  boundary  line  towards  Quebec  province.  South  of  the  point  men 
tioned  above,  the  water  basin  of  the  Magalloway  occupies  a  large  tract  of 
country  in  New  Hampshire.  It  is  everywhere  broken  into  irregular 
mountain  ridges,  but  these  have  generally  a  southern  trend  until  we  reach 
the  Swift  Diamond  in  Dartmouth  College  grant.  South  of  this  stream 
there  is  a  high,  continuous  ridge  from  Dixville  notch  to  the  Magollaway : 
then  there  is  a  high  ridge  that  runs  south,  parallel  with  the  stream  last 
mentioned.  The  triangular  area,  embraced  by  the  Swift  Diamond,  Clear 
stream,  and  the  Magalloway  and  Androscoggin,  is  a  succession  of  hills 
and  mountain  ridges.  The  high  point  north  of  Dixville  notch  forms  the 
apex  of  the  triangle ;  and  Mt.  Dustan  is  in  the  north-east  angle.  South 


222  PHYSICAL   GEOGRAPHY. 

of  Clear  stream  the  hills  are,  if  possible,  more  irregular  in  their  contour 
than  those  northward. 

THE   STREAMS. 

The  principal  streams  are  the  Connecticut,  the  Magalloway,  and  the 
Androscoggin.  Almost  on  the  very  northern  boundary  of  New  Hamp 
shire,  and  nearly  on  the  very  summit  of  the  dividing  ridge  that  separates 
the  waters  of  the  St.  Lawrence  from  those  that  flow  southward,  there  is 
a  small  lake  containing  only  a  few  square  acres ;  and  this  is  the  source  of 
the  Connecticut  river.  It  has  an  elevation  of  2,551  feet,  and  is  only 
seventy-eight  feet  below  the  summit  of  Mt.  Prospect;  and  so  remote 
is  it  from  the  habitations  of  men  that  it  is  rarely  seen.  A  place  more 
solitary  I  know  not  in  northern  New  Hampshire.  Surrounded  as  it  is  by 
dense  forests  of  evergreen,  you  can  see  only  these  and  the  waters  of  the 
lake.  Almost  the  only  sound  that  relieves  the  monotony  of  the  place  is 
the  croaking  of  the  frogs,  and  this  must  be  their  paradise.  A  few  steps 
to  the  summit  of  Mt.  Prospect,  and  we  can  overlook  thousands  and 
thousands  of  square  miles  of  forests  in  Quebec  province,  while  in  the 
extreme  distance  to  the  north-west  can  be  seen  the  habitations  of  men. 
Southward  the  view  is  not  extensive.  The  outlet  of  the  lake  just  men 
tioned  is  a  mere  rill ;  this  flows  into  Third  lake.  This  lake  is  half  a  mile 
directly  south  of  the  boundary,  and  has  an  area  of  three  fourths  of  a 
square  mile,  and  its  height  is  2,038  feet.  It  is  trapezoidal  in  shape,  and 
has  its  greatest  width  on  the  south,  while  its  northern  shore  is  not  more 
than  a  quarter  of  a  mile  in  length.  Its  outlet  is  at  the  south-east  corner, 
and  its  width  is  eight  feet,  and  its  depth  six  or  eight  inches.  Besides  the 
spruce  and  firs  and  cedars  of  immense  size,  it  has  a  sub-alpine  vegetation. 
Labrador  tea,  the  ledum  palustre,  is  found  in  abundance  along  its  shores. 
In  early  summer,  before  the  swarms  of  insects  come,  it  is  charming  to 
stand  upon  its  border,  when  not  a  ripple  disturbs  its  placid  waters,  and  the 
trees  are  mirrored  along  its  shores.  On  every  side  except  the  south,  the 
hills,  which  rise  to  mountain  heights,  approach  almost  to  its  very  shores. 
The  Connecticut,  which  is  its  outlet,  is  nowhere  remarkably  rapid. 
About  five  miles  from  the  lake  it  receives  a  tributary  from  the  east,  the 
principal  branch  of  which  rises  near  the  boundary.  This  stream  is  nearly 
as  large  as  that  into  which  it  flows.  A  mile  and  a  half  from  where  it 


TOPOGRAPHY  OF  COOS  COUNTY.  223 

receives  this  tributary,  it  flows  into  Second  lake.  This  lake  is  two  miles 
and  three  fourths  in  length,  and  in  the  widest  part  it  is  little  more  than  a 
mile,  and  the  height  above  the  sea  is  1882  feet.  Its  area  is  about  one 
and  three  fourths  square  miles.  It  is  one  of  the  most  beautiful  of 
our  northern  lakes.  The  graceful  contour  of  its  shores,  the  symmetry  of 
its  projecting  points,  the  stately  growth  of  its  primeval  forests,  the  carpet 
of  green  that  is  spread  along  its  border  and  extends  through  the  long 
vista  of  the  woods,  the  receding  hills  and  the  distant  mountains,  present 
a  combination  of  the  wild,  the  grand,  and  the  beautiful  that  is  rarely  seen. 
Near  its  northern  border,  besides  the  Connecticut,  it  receives  two  tributa 
ries,  one  from  the  north-east  and  one  from  the  north-west.  Its  outlet  is 
on  the  west  side,  near  its  southern  limit;  it  is  forty  feet  in  width,  and  has 
a  depth  of  eighteen  inches.  Twenty  rods  from  the  lake  it  has  a  fall  of 
eighteen  feet  or  more  ;  then  its  descent  is  quite  gradual,  but  forms  here 
and  there  deep  eddies.  A  mile  from  the  lake  it  becomes  more  rapid,  and 
rushes  down  between  precipitous  walls  of  rock  in  a  series  of  wild  cas 
cades,  which  continue  for  half  a  mile.  It  receives  two  tributaries  from 
the  west  before  it  flows  into  Connecticut  lake.  Here  we  find  a  sheet  of 
water  exceedingly  irregular  in  its  outline.  Its  length  is  four  miles,  and 
its  greatest  width  two  and  three  fourths,  and  it  contains  not  far  from  three 
square  miles.  Its  general  direction  is  east  and  west,  but  near  its  outlet 
it  turns  towards  the  south.  None  of  these  lakes  contain  islands  to  any 
extent.  Second  lake  has  only  one,  and  this  has  two,  but  they  are  very 
near  the  south-east  shore.  On  the  west  shore  of  this  lake  the  country 
is  settled,  and  the  grassy  pastures  extend  down  to  its  border ;  but  for 
the  most  part  it  is  still  surrounded  by  a  primeval  forest.  As  many  of 
the  neighboring  hills  are  crowned  with  deciduous  trees,  particularly  the 
maple,  in  autumn,  when  the  frost  comes  and  these  have  put  on  their 
crown  of  beauty,  of  crimson  and  scarlet,  of  yellow  and  gold,  and  mingled 
as  they  often  are  with  the  dark  foliage  of  the  spruce  and  fir,  we  have  a 
scene  which,  in  brilliancy  and  beauty,  is  rarely  if  ever  excelled.  There  is 
another  element  characteristic  of  this  high  elevation,  for  the  lake  is  1,619 
feet  above  the  sea.  It  often  happens,  when  the  forest  has  put  on  this  robe 
of  beauty,  that  all  the  neighboring  heights  are  of  immaculate  whiteness 
from  the  frozen  mist  that  clings  to  every  spray  of  the  evergreen  foliage. 
Embraced  in  the  picture  are  the  blue  waters  of  the  lake,  the  belt  of

deciduous  forests,  with  their  brilliant,  gorgeous  colors,  the  dark  bands  of 
the  evergreens,  and  the  snow-white  summits.  The  water  at  the  outlet 
flows  over  a  rocky  barrier,  the  stream  falling  abruptly  nearly  thirty-seven 
feet.  The  fall  is  quite  rapid  for  two  miles  and  a  half:  then  the  flow  is 
more  gentle  for  about  four  miles :  then  it  becomes  more  rapid  again,  and 
continues  thus  until  after  it  passes  West  Stewartstown.  It  is  then 
nowhere  a  sluggish  stream,  and  has  rapids  in  many  places  until  it  gets 
below  the  falls  of  Northumberland :  then  it  is  the  most  placid  of  streams 
until  it  reaches  the  Fifteen-mile  falls,  which  begin  in  Dalton.  The  fall 
from  Connecticut  lake  to  Lancaster  is  785  feet.  In  New  Hampshire, 
below  Connecticut  lake,  the  Connecticut  river  receives  three  large  tribu 
taries, — Perry's  stream,  which  rises  near  Third  lake,  and  has  a  rapid 
descent,  including  two  falls  three  and  five  miles  from  its  confluence,  a 
mile  and  a  half  from  the  lake ;  Indian  stream,  which  rises  on  the  bound 
ary,  has  a  very  rapid  descent  for  five  or  six  miles,  when  it  is  a  very  quiet 
stream  until  it  flows  into  the  Connecticut  about  eleven  miles  from  the 
lake ;  Hall's  stream,  which  rises  also  on  the  boundary,  and  is  the  dividing 
line  between  New  Hampshire  and  Quebec  province.  Besides  these  there 
are  several  smaller  streams.  The  principal  streams  from  the  east  are 
Cedar  stream  in  Pittsburg,  Labrador  brook  and  Dead  Water  stream  in 
Clarksville,  the  Mohawk  in  Colebrook,  Sims  stream  and  Lyman  brook  in 
Columbia,  Bog  brook  in  Stratford,  the  Upper  Ammonoosuc  in  Northum 
berland,  Israel's  river  in  Lancaster,  and  John's  river  in  Dalton. 

The  Magalloway  has  its  principal  source  in  Lake  Magalloway,  about  a 
mile  and  a  half  south-west  of  Crown  monument.  This  lake  is  one  of  the 
most  romantic  in  New  Hampshire.  It  has  an  elevation  of  2,225  feet 
above  the  sea.  Its  area  is  not  far  from  from  320  square  acres,  and  is 
surrounded  by  hills  that  rise  to  mountain  heights,  the  elevation  on  the 
north-east  being  587  feet  above  the  lake,  and  from  its  summit  we  look 
immediately  down  upon  it.  The  stream  which  is  its  outlet  forms,  a 
few  steps  from  the  lake,  a  beautiful  cascade  some  twenty  feet  in  height. 
Of  all  the  men  who  have  hunted  in  these  forests,  I  have  found  only  one 
who  has  ever  seen  this  lake.  If  it  were  within  the  reach  of  travel,  it 
would  no  doubt  attract  many  persons,  for  in  wildness  and  grandeur  it  is 
not  surpassed.  Its  outlet  is  soon  augmented  by  streams  both  from  New 
Hampshire  and  Maine.

The  Magalloway,  soon  after  it  enters  the  state  of  Maine,  forms  one  of 
the  peculiar  streams  in  this  northern  country.     It  flows  for  a  time  with 


Fig.  42. — VIEW   ON   THE   UPPER   MAGALLOWAY. 

a  rapid  current,  and  then  for  a  long  distance  it  is  the  most  sluggish 
of  streams,  often  deeper  than  it  is  wide,  while  on  either  side  there  are 
numerous  ponds  or  bogs.  Parmachena  lake,  into  which  it  flows,  is  about 
the  size  of  Connecticut  lake.  For  four  miles  below  Parmachena  the 
stream  is  very  rapid,  and  then,  for  almost  the  entire  distance  to  Escahos 
falls,  the  descent  is  slight.  Upper  Magalloway  settlement  lies  above  the 
falls.  The  Magalloway  enters  New  Hampshire  in  Dartmouth  College 
grant.  It  flows  about  a  mile,  and  then  goes  into  Maine,  but  enters  New 
Hampshire  again  in  the  north-east  corner  of  Wentworth's  Location,  and 
flows  into  the  Androscoggin  a  mile  and  a  quarter  from  Umbagog  lake. 
Although  the  river  is  very  crooked,  yet  the  water  is  of  sufficient  depth 
so  that  a  steamer  runs  up  nearly  to  the  Maine  line.  The  steamer  runs 
down  the  Androscoggin  to  Errol  dam:  below  this  the  Androscoggin  is 
for  the  most  part  quite  rapid,  and,  in  the  sixty-six  miles  of  this  river  in 
New  Hampshire,  the  fall  is  464  feet.  The  tributaries  of  the  Magalloway 
and- Androscoggin  from  New  Hampshire  are  the  Little  Magalloway,  four 
and  a  half  miles  south  of  Parmachena  lake,  and  the  Swift  Diamond,  which 
has  its  source  in  the  Diamond  ponds  in  Stewartstown,  and  has  a  tribu 
tary,  the  Dead  Diamond,  which  rises  two  and  a  half  miles  south-east  of 
Second  lake,  and  flows  into  the  Swift  Diamond  a  mile  and  a  half  from  its 
confluence  with  the  Magalloway  in  Dartmouth  College  grant.  Clear 
stream  flows  into  the  Androscoggin  in  Errol.  In  Gorham  the  tributaries 
are  Moose  and  Peabody  rivers,  the  latter  of  which  rises  in  the  Great  Gulf

between  Mt.  Washington  and  Mt.  Adams.  A  considerable  tributary, 
Wild  river,  rises  in  Bean's  purchase,  but  flows  into  the  Androscoggin  in 
Maine.  Besides  these  from  the  west,  the  Androscoggin  has  three  tribu 
taries  in  New  Hampshire  from  the  east, — the  Molichewock  in  Errol,  and 
the  Chickwolnepy  and  Stearns  brooks  in  Milan.

CHAPTER    IX. 

TOPOGRAPHICAL    MAPS    OF    THE    STATE. 

,NE  of  the  first  essentials  to  a  knowledge  of  the  natural  resources 
of  a  state  is  an  acquaintance  with  its  topographical  features  in 
relation  to  population.  The  position  of  villages,  mountains,  roads, 
streams,  lakes,  etc.,  must  be  known  before  any  kind  of  important  com 
mercial  transactions  can  be  effected.  Our  predecessors  understood  the 
importance  of  maps,  since  they  commenced  a  century  since  to  order  their 
construction, — long  before  many  other  states  seemed  to  appreciate  their 
importance.  But  a  new  one  is  needed  now.  We  have  endeavored  to 
construct  one  that  is  reliable,  drawing  upon  our  own  private  resources  for 
want  of  public  patronage.  It  is  employed  as  the  base  chart  for  repre 
senting  the  geology  in  this  report. 

In  view  of  the  importance  of  maps  to  the  progress  of  civilization,  I 
have  thought  it  best  to  sketch  the  history  of  the  official  charts  of  New 
Hampshire,  describing  those  in  particular  which  have  been  published 
under  legislative  sanction,  and  stating  the  most  important  improvements 
in  the  one  constructed  under  our  direction. 

The  first  known  map  of  the  state  was  edited  by  Joseph  Blanchard  and 
Samuel  Langdon,  and  published  at  Portsmouth  in  1761.  I  have  not  been 
able  to  find  a  copy  of  it  anywhere,  and  therefore  will  not  attempt  to 
describe  it.  The  next  was  Holland's.  Dr.  William  Prescott,  of  Concord, 
possesses  a  copy  of  this,  which  has  preserved  much  of  its  original  fresh

appearance  ;  and  he  kindly  loaned  it  to  us  for  examination  and  copy,  by 
the  heliotype  process,  for  this  report. 

HOLLAND'S  MAP. 

In  1773  and  1774,  Capt.  Samuel  Holland  made  a  survey  of  the  prov 
ince  at  the  public  expense.  Owing  to  the  disturbances,  which  commenced 
immediately  afterwards,  the  map  was  not  engraved  till  1784,  in  London, 
and  by  the  direction  and  at  the  expense  of  Paul  Wentworth,  Esq. 
Belknap  says  of  it,  in  the  third  volume  of  his  history,  bearing  date  of 
1792,  in  the  preface:  "Those  parts  which  were  actually  furnished  by 
Holland,  or  his  assistants,  are  laid  down  with  great  accuracy.  The 
eastern  boundary  line  and  the  parts  connected  with  it  were  not  surveyed, 
but  taken  from  such  materials  and  information  as  could  at  that  time  be 
collected."  Belknap  has  compiled  a  smaller  map  from  Holland's  for  his 
work,  upon  which  he  placed  a  few  improvements,  including  the  straight 
line  finally  agreed  upon  by  the  assembly  to  take  the  place  of  the  con 
spicuous  "Masonian  curve,"  appearing  both  upon  Holland's  and  Carri- 
gain's  map.  I  quote  Belknap' s  account  of  the  final  settlement  of  the 
matter.* 

It  was  observed,  in  the  course  of  the  preceding  work,  that  the  Masonian  proprietors 
claimed  a  curve  line  as  their  western  boundary,  and  that  under  the  royal  government 
no  person  had  controverted  that  claim.  When  the  war  with  Great  Britain  was  termi 
nated  by  the  peace  of  1783,  the  grantees  of  some  crown  lands,  with  which  this  line 
interfered,  petitioned  the  assembly  to  ascertain  the  limits  of  Mason's  patent.  The 
Masonians  at  the  same  time  presented  a  petition  showing  the  pretension  which  they 
had  to  a  curve  line,  and  praying  that  a  survey  of  it,  which  had  been  made  in  1768  by 
Robert  Fletcher,  might  be  established.  About  the  same  time  the  heirs  of  Allen, 
whose  claim  had  long  lain  dormant  for  want  of  ability  to  prosecute  it,  having  consulted 
council  and  admitted  some  persons  of  property  into  partnership  with  them,  entered 
and  took  possession  of  the  unoccupied  lands  within  the  limits  of  the  patent,  and,  in 
imitation  of  the  Masonians,  gave  general  deeds  of  quit-claim  to  all  bonafide  purchasers, 
previously  to  the  first  of  May,  1785, — which  deeds  were  recorded  in  each  county,  and 
published  in  the  newspapers.  They  also  petitioned  the  assembly  to  establish  a  head 
line  for  their  patent. 

After  a  solemn  hearing  of  these  claims,  the  assembly  ordered  a  survey  to  be  made  of 
sixty  miles  from  the  sea,  on  the  southern  and  eastern  lines  of  the  state,  and  a  straight 
line  to  be  run  from  the  end  of  one  line  of  sixty  miles  to  the  end  of  the  other.  They

TOPOGRAPHICAL    MAPS    OF    THE    STATE.  229 

also  passed  an  act  to  quiet  all  bona  fide  purchasers  of  lands  between  the  straight  and 
curve  lines,  so  far  as  that  the  state  should  not  disturb  them.  This  survey  was  made  in 
1787  by  Joseph  Blanchard  and  Charles  Clapham.  The  line  begins  on  the  southern 
boundary,  at  lot  No.  18  in  the  town  of  Rindge.  Its  course  is  N.  39°  E.  Its  extent  is 
93i  miles.  It  ends  at  a  point  in  the  eastern  boundary,  which  is  seven  miles  and  two 
hundred  and  six  rods  northward  of  Great  Ossapy  river.  This  line  being  established 
as  the  head  line  or  western  boundary  of  Mason's  patent,  the  Masonians,  for  the  sum 
of  forty  thousand  dollars  in  public  securities  and  eight  hundred  dollars  in  specie,  pur 
chased  of  the  state  all  its  right  and  title  to  the  unoccupied  lands  between  the  straight 
line  and  the  curve.  The  heirs  of  Allen  were  then  confined  in  their  claim  to  those 
waste  lands  only,  which  were  within  the  straight  line.  They  have  since  compromised 
their  dispute  with  the  proprietors  of  eleven  of  the  fifteen  Masonian  shares,  by  deeds  of 
mutual  quit-claim  and  release.  This  was  clone  in  January,  1790. 

The  following  is  the  title  of  the  map  upon  its  face : 

A  Topographical  Map  of  tJie  State  of  New  Hampshire:  Surveyed  under  the  Direc 
tion  of  Samuel  Holland,  Esqr,  Surveyor  General  for  the  Northern  District  of  North 
America ;  by  the  following  Gentlemen,  his  Deputies  :  Mr.  Thomas  Wright,  Mr.  George 
Sproule,  Mr.  James  Grant,  Mr.  Thomas  Wheeler  and  Mr.  Charles  Blaskowitz. 
London:  Printed  for  William  Faden,  Geographer  to  the  King.  Charing  Crofs, 
March  first,  1784. 

ADVERTISEMENT. 

The  respective  parts  of  this  Plan  were  arranged  by  the  several  Gentlemen  concerned 
with  all  pofsible  accuracy,  and  afterwards  rectified  by  Samuel  Holland  Esq.  from  the 
Astronomical  Observations  made  by  him  at  Portsmouth,  Wentworth  House,  Newbury 
Port  and  Cape  Anne  and  those  made  by  Mr.  Wright  at  Hensdale  and  the  Pine  Tree 
at  Dracutt. 

By  these  Surveys  thus  adjusted  the  Form  of  the  Province  is  exactly  determined 
except  as  to  its  Eastern  Boundary  Line,  which  is  laid  down  with  the  several  Parts 
dependent  thereon  from  such  materials  as  were  given  in :  Whatever  relates  therefore  to 
that  line,  must  depend  on  their  authenticity  and  goodnefs. 

The  Bounds  of  the  several  Townships  and  Patents  were  delineated  from  Descrip 
tions  in  the  Public  Offices,  or  Surveys  made  for  the  use  of  the  State  and  the  Parties 
concerned  :  It  is  pofsible  some  Tracts  which  were  granted  or  patented  at  the  execution 
of  this  Plan  are  omitted,  should  there  be  any  such  it  must  be  attributed  to  the  necefsary 
materials  for  describing  them  not  having  been  sent  in  :  Which  is  also  the  reason  that 
some  Townships  appear  more  compleatly  laid  down  than  others  that  are  perhaps  as 
well  settled. 

Some  of  the  special  features  of  this  map  will  be  stated  next. 
Townships  retaining  the  same  names  as  at  present,  and  the  same,  or 
not  very  different,  boundaries :

The  following  towns  appeared  without  intervening  boundaries,  which 
probably  were  essentially  their  present  ones :  Newington,  Portsmouth, 
Greenland,  Rye,  Hampton  and  Hampton  Falls  ;  Kingston,  Newtown, 
Plaistow,  Hampstead,  New  Salem  (Salem  and  Atkinson),  and  Pelham  ; 
Brentwood  and  Fremont  (Polin). 

The  following  towns  had  about  the  same  boundaries  as  at  present, 
but  different  names :  Hudson  (Nottingham  West),  Manchester  (Derry- 
field),  Nashua  (Dunstable),  Brookline  (Raby),  Sharon  (Peterborough  Slip), 
Troy  and  Maryborough  (Oxford),  Nelson  (Packersfield),  Stoddard  (Lim

Goshen  and  Sunapee  (Saville),  Springfield  (Protectworth),  New  London

Jefferson  (Dartmouth),  Stark  (Percy),  Stratford  (New  Stratford),  Columbia 
(Cockborne),  Randolph  (Durand),  Gorham  (Shelburne  Addition),  Berlin 
(Mainsburgh),  Milan  (Paulsburgh). 

The  following  are  marked  off  without  names :  Somersworth,  the  lower 
part  of  Ossipec,  and  Lebanon. 

In  addition  to  the  territories  embraced  under  their  present  appellations, 
the  following  towns  included  additional  area:  Rochester  added  Farming- 
ton  and  Milton ;  Barrington  added  Strafford ;  Chester  added  Auburn  and 
Hooksett ;  Chichester  included  Pittsfield ;  Londonderry  included  Derry ; 
"Society  Lands"  included  Deering,  Francestown,  Antrim,  Hancock,  and 
Greenfield ;  Canterbury  included  Northfield ;  Gilmanton  added  Belmont 
and  Gilford ;  Eaton  embraced  much  of  Ossipee,  Madison,  and  Freedom. 
Kilkenny  and  Percy  (Stark)  seem  to  have  been  magnified  to  three  or 
four  times  their  proper  width,  and  the  straight  east  boundary  is  made  to 
run  due  north  and  south.  The  White  Mountain  and  Upper  Coos  regions 
were  scarcely  infringed  upon  by  boundaries. 

The  importance  of  this  map  has  induced  us  to  reproduce  it  in  the  atlas 
as  a  fac-simile  of  one  fourth  the  size  of  the  original.  For  that  reason, 
those  interested  in  the  changes  of  boundaries  and  names  that  have  taken 
place  since  New  Hampshire  ceased  to  be  a  province  of  King  George  the 
Third,  may  glean  further  items  of  interest  by  actual  inspection.  For  the 
same  reason,  it  is  not  desirable  to  state,  in  detail,  the  position  of  the 
numerous  gores  and  grants  that  have  been  absorbed  into  adjacent  town 
ships.  I  cannot  forbear,  however,  to  refer  to  the  origin  of  the  name 
Kearsarge.  Holland  says, — "Kyar  Sarga  mountain:  by  the  Indians, 
Cowissewaschook."  The  name  seems  to  have  been  derived  from  that  of 
a  Mr.  Hezekiah  Sargent, — corrupted  by  usage  into  Kearsarge.  It  is  not, 
therefore,  of  Indian  origin,  as  supposed  by  many.  Furthermore,  Kear 
sarge,  in  Warner,  seems  to  have  been  the  only  mountain  of  that  name  in 
1784.  Hence,  when  the  early  settlers  of  Bartlett  carried  with  them  the 
name  of  their  favorite  mountain,  and  applied  it  to  a  new  peak  in  Chatham, 
it  cannot  be  expected  that,  in  these  days  of  rapid  transit,  we  should 
employ  the  same  name,  or  even  the  corruption  of  AYarsarge,  for  the  latter. 
It  is  best  to  retain  the  original  name  of  Pigwacket  or  Pequawket,  as  I 
have  endeavored  to  do  uniformly  in  this  report  and  on  the  new  map. 

A  similar  transfer  of  names  is  seen  at  Colebrook.     A  fine  mountain, 


232  PHYSICAL    GEOGRAPHY. 

directly  opposite  the  village,  is  named  Monadnock,  for  the  same  reason  as 
in  the  other  instance.  This  peak  is  in  another  state,  and  is  not  visited  at 
all  by  tourists.  Hence  it  is  not  worth  while  to  attempt  any  change  in  its 
designation  at  present,  though  it  may  be  desirable  hereafter. 

The  north  boundary  of  the  state  is  placed  at  45°  north  latitude.  This 
may  have  been  occasioned  by  the  change  of  the  relations  of  the  province, 
in  1784,  to  the  mother  country. 

CARRIGAIX'S  MAP. 

The  legislatures  of  1803  and  1805  directed  that  a  map  of  the  state 
should  be  compiled  under  the  direction  of  the  secretary  of  state,  Philip 
Carrigain,  from  town  surveys  returned  to  the  secretary's  office.  The 
map  was  made  by  joining  together  numerous  separate  surveys  of  town 
ships  made  by  different  engineers,  and  consequently  of  variable  value. 
It  was  not  published  till  1816. 

Were  care  taken  to  discover  all  the  steps  of  the  process  of  the  manu 
facture  of  this  projection,  the  space  of  several  chapters  would  be  occupied 
by  their  rehearsal.  The  fact  that  eleven  years  passed  while  the  work  was 
preparing,  indicates  that  much  tribulation  must  have  been  endured  by  the 
author  in  his  attempts  to  average  the  errors.  His  results,  with  which 
alone  we  need  now  be  concerned,  were  exceedingly  creditable,  both  to  the 
author  and  to  the  state.  I  do  not  recall  the  existence  of  any  state  map 
in  the  country  so  good  as  this,  which  was  published  at  so  early  a  period. 
What  are  now  seen  to  have  been  defects  in  the  plan  of  its  construction 
were  unavoidable  at  that  time,  without  the  experience  of  subsequent 
years  of  labor  by  engineers. 

The  atlas  contains  a  half-size  fac-similc  of  Carrigain's  map,  which  may 
be  consulted  in  connection  with  the  description,  or  for  more  minute  study 
of  localities.  It  was  copied  from  uncolored  sheets,  kindly  furnished  by 
Hon.  S.  N.  Bell.  The  following  is  the  title  of  it,  which  is  not  reproduced 
in  the  heliotype. 

NEW  HAMPSHIRE  By  recent  survey  made  under  the  Supreme  Authority  and 
published  according  to  law  by  Philip  Carrigain  Councillor  at  Law  and  late  secretary  of 
state.  To  His  Excellency  John  Taylor  Gilman  Esq,  and  to  the  Honorable  the  Legisla 
ture  of  the  State  of  New  Hampshire,  this  map  commenced  under  their  auspices  and 
matured  by  their  patronage  is  most  respectfully  inscribed  by  their  obliged  servant, 
Philip  Carrigain.  Concord,  1816. 


TOPOGRAPHICAL    MAPS    OF    THE    STATE.  233 

Connected  with  this  title  is  a  large  colored  vignette,  six  by  ten  inches 
in  dimensions.  The  title  is  inscribed  upon  the  side  of  a  shield-like  cliff, 
with  evergreens  upon  its  summit,  and  an  eagle  feeding  her  young. 
Behind  are  several  very  high  mountain  peaks.  On  the  left  is  a  large 
cataract  adjacent  to  the  Willey  house,  and  a  hunter  shooting  at  a  moose 
on  the  border  of  a  lake, — perhaps  Winnipiseogee.  On  the  right  seems 
to  be  the  ocean  leading  out  of  Portsmouth  harbor,  with  a  tower  on  an 
island,  large  ships,  and  a  long  arched  bridge  leading  to  Portsmouth. 
Nearer  to  the  front  is  an  extensive  canal  lock,  and  people  engaged  in 
agricultural  operations, — ploughing  and  fishing.  Directly  in  front  of  the 
title  shield  are  miscellaneous  objects,  as  cannon,  the  state  insignia,  rolls, 
baskets,  etc.  The  name  of  the  state  is  written  in  very  large  letters  over 
the  vignette,  and  the  dedication  is  placed  beneath.  Three  side  sketches 
are  the  gap  of  the  White  Mountains,  view  of  the  Great  Boar's  Head  with 
Hampton  beach,  and  the  White  Mountains  from  Shelburne.  Some  of 
these  will  be  reproduced  with  the  map.  Their  vertical  scale  is  so  much 
exaggerated  that  they  are  objects  of  curiosity.  There  are  two  side  maps, 
not  reproduced :  the  first,  of  New  England  and  the  Dominion  of  Canada ; 
the  second,  the  United  States  as  far  as  the  Mississippi  river.  The  early 
period  of  the  issue  of  the  map  is  appreciated,  when  it  appears  that  Illinois, 
Indiana,  and  Michigan  are  represented  here  as  territories.  The  following 
text  on  the  side  of  the  map,  relating  to  the  state,  may  be  of  historic 
interest. 

NEW  HAMPSHIRE  is  bounded  on  the  E.  by  Maine,  and  the  Atlantic;  S.  by 
Massachusetts ;  W.  by  the  west  bank  of  the  river  Connecticut  as  far  as  Lat.  45,  and 
then  by  Lower  Canada  to  Maine. 

The  line  which  divides  New  Hampshire  from  Maine,  commencing  at  East  Pond,  and 
extending  to  the  north-east  boundary  of  the  state,  was  taken  from  three  surveys,  made 
in  1741,  1768  and  1789;  and  is  properly  three  lines. 

The  first  surveyor  allowed  too  much  for  the  westerly  variation;  and  the  others, 
successively  adhering,  at  the  periods  of  their  respective  surveys  to  the  same  allowance, 
notwithstanding  the  continual  retrogression  of  the  needle,  thereby  increased  the  error, 
and  actually  made  three  distinct  courses. 

The  royal  order  of  1740,  by  which  this  line  should  have  progressed  N.  2°  W.,  has 
therefore  never  been  carried  into  effect. 

The  southern  boundary  from  the  Pine,  at  the  south-east  corner  of  Pelham,  to  the 
river  Connecticut,  was  measured  in  1741,  and  was  intended  to  have  been  a  due  west 
VOL.  I.  32

line ;  but  a  similar  allowance  for  the  magnetic  change  having  been  adopted,  gave  it  an 
inclination  injurious  to  N.  H.  Yet  how  far  the  erroneous  mode,  then  in  practice,  of 
running  parallels  by  perpendiculars  counteracted  the  mistake  in  the  allowance  for 
A-ariation,  remains  to  be  determined  by  proper  observations,  yet  to  be  made  at  the 
extremities  of  this  line. 

But  under  present  circumstances  the  calculations  of  Mr.  Wright,  made  in  1773,  have 
been  deemed  from  necessity  the  safest  basis  for  this  projection. 

With  regard  to  the  face  of  the  country,  its  features  are  striking  and  picturesque. 
The  natural  scenery  of  mountains  of  greater  elevation  than  any  others  in  the  UNITED 
STATES ;  of  lakes,  of  cataracts,  of  vallies,  furnishes  a  profusion  of  the  sublime  and 
beautiful.  It  may  be  called  the  Switzerland  of  AMERICA.  The  extreme  coldness  of 
the  winter  is  alleviated  by  the  convivial  hospitality  of  that  season ;  and  [is]  more  than 
compensated  by  the  salubrity  of  the  air  and  other  delights  of  the  summer.  Industry 
morality  and  piety  characterize  the  public  manners,  and  this  state  richly  participates  in 
those  advancements  in  science  and  that  high  grade  of  refinement,  so  general  in  NEW 
ENGLAND.  Although  the  soil,  for  the  most  part,  is  better  adapted  to  pasturage, 
than  agriculture ;  yet  a  great  portion  of  it  is  fertile,  and  produces  maize  and  other 
grains  abundantly.  Elections  are  annual ;  the  Townships  are  distinct  corporations, 
and  slavery  is  unknown.  N.  H.  was  discovered  in  1614,  and  its  settlement  commenced 
in  1623.  Its  population  had  advanced  in  1770  to  63,761,  in  1780  to  102,131,111  1798 
to  142,018,  in  1800  to  183,663,  and  in  1810  to  214,460.  The  State  is  restricted 
to  one  harbor,  which  is  at  PORTSMOUTH,  and  is  second  to  none  in  AMERICA. 
CONCORD  is  the  present  seat  of  Government. 

The  variation  of  the  magnetic  needle  is  given  thus  :  Latitude  45,  1807, 
7°  33'.  Dartmouth  college,  1808,  7°  21'.  Concord,  1810,  7°  if. 

The  scale  is  stated  to  be  three  miles  to  the  inch,  or  rather  that  seems 
to  have  been  the  intention.  Careful  measurements  upon  our  copy  indi 
cate  it  to  be  3.4  miles  to  the  inch.  The  variation  is  undoubtedly  due  to 
the  contraction  of  the  paper  by  drying  after  the  impression  had  been 
printed  upon  it.  Every  map  thus  prepared  is  liable  to  modification  for 
the  same  reason,  and  measurements  should  always  be  made  from  the 
scale  engraved  on  the  face  of  the  map,  rather  than  from  a  foot-rule. 

The  general  appearance  of  the  map  is  a  great  improvement  over  Hol 
land's,  having  been  engraved  upon  copper.  The  mountains,  rivers,  and 
various  boundary  lines  are  given  with  much  greater  precision.  The 
northern  boundary  is  given  very  nearly  as  it  was  finally  settled  by  the 
commissioners.  The  wedge  of  Percy  and  Kilkenny,  between  the  east 
and  west  townships  in  Coos  county,  has  been  reduced  to  respectable 
limits.  Most  of  the  grants  and  gores  have  been  merged  into  townships ; 


TOPOGRAPHICAL    MAPS    OF    THE    STATE.  235 

and   county  lines   are   given  for  Rockingham,   Hillsborough,  Cheshire, 
Strafford,  Grafton,  and  Coos. 

Taking  the  town  improvements  over  Holland's  map  by  counties,  it  may 
be  said  of  Rockingham  that  Canterbury  and  Chichester  have  been 
divided;  Sandown,  East  Kingston,  and  Hawke  (Danville)  have  been 
taken  out  of  Kingston ;  Atkinson  and  Windham  are  eliminated ;  and  the 
shore  towns  have  their  boundaries  inserted.  In  Hillsborough,  Mont 
Vernon  and  Milford  came  essentially  from  Amherst ;  Raby  has  become 
Brookline;  Derryfield,  Manchester;  Peterborough  Slip,  Sharon.  Only  a 
half  township  of  the  "Society  Land"  is  left  unassigned.  Warner,  New 
London,  Wilmot,  Andover,  and  Sutton  have  received  their  present  names. 
In  Cheshire,  Marlborough,  Roxbury,  Sullivan,  Langdon,  Washington, 
Goshen,  and  Springfield  make  their  appearance  for  the  first  time.  The 
present  town  of  Sunapee  is  called  Wendell. 

In  Strafford,  Somersworth  has  a  name ;  Rochester  is  divided  as  now. 
East  Town  becomes  Wakefield ;  Ossipee,  Center  Harbor,  Alton,  Brook- 
field,  New  Hampton,  and  Burton  (Albany)  have  an  existence,  because 
incorporated  since  1784.  In  Grafton,  Lebanon  receives  a  name;  Relhan 
becomes  Enfield ;  Cardigan,  Orange ;  Cockermouth,  Groton ;  Trecothick 
and  Fairfield  are  merged  into  Ellsworth,  Peeling  (Woodstock),  and  Coven 
try  (Benton);  Franconia  and  Lincoln  are  properly  divided;  Lisbon  has 
the  name  of  Concord ;  and  Lyman.  remains  as  before,  including  the 
present  town  of  Monroe.  In  Coos,  Chatham,  Adams  (Jackson),  Bartlett, 
Success,  and  Dixville  are  new  townships.  Shelburne  is  not  divided  as  on 
Holland's;  Dalton  has  been  separated  from  Littleton  (Apthorp);  and 
there  are  six  grants  not  previously  mentioned.  The  names  of  Jefferson, 
Stratford,  and  Columbia  are  also  new. 

Both  maps  show  the  supposed  course  of  the  "ancient  Masonian  curve 
line."  This  will  not  be  reproduced  on  the  new  map,  as  it  has  ceased  to 
be  of  any  practical  importance,  though  it  has  apparently  determined  the 
west  town  lines  of  Fitzwilliam,  Stoddard,  and  Washington. 

Carrigain's  map  shows  the  population  in  figures  engraved  upon  the  face 
of  each  town.  Kearsarge  is  applied  where  it  belongs ;  and,  in  Chatham, 
Pigwacket  mountain  is  said  to  have  been  formerly  called  Kiarsarge.  There 
is  an  improvement  over  existing  usage  in  regard  to  the  Merrimack  river. 
It  is  made  to  rise  at  the  foot  of  Mt.  Willey,  and  the  name  Merrimack  is

applied  to  the  east  branch  of  the  Pemigewasset.  But  the  name  of  Pemi- 
gewasset  is  preserved  as  a  synonym,  as  it  should  be.  The  stream  coming 
down  from  Franconia  is  called  the  Middle  Branch. 

The  roads  are  laid  down  well  in  accordance  with  the  old  method  of 
presenting  the  general  course,  without  reference  to  their  minor  irregu 
larities. 

PROF.  WOODMAN'S  REPORT. 

In  1853  the  governor  was  directed  to  "appoint  a  commissioner  to 
obtain  the  necessary  information,  and  make  estimates  of  the  expense  of 
constructing  %a  new  and  accurate  map  of  the  state."  In  his  report  the 
following  year,  Prof.  John  S.  Woodman,  the  commissioner,  answers  four 
questions,  viz., — What  data,  information,  or  facts  are  already  within  reach 
for  the  construction  of  a  new  map  ?  What  are  necessary  yet  to  be  obtained 
for  a  new  and  accurate  map  by  actual  operations  in  the  field  ?  What  is  the 
time  and  expense  necessary  for  obtaining  all  that  is  required,  and  con 
structing  a  map  ?  What  is  the  expense  of  engraving,  printing,  and  manu 
facturing?  The  answer  he  gives  to  the  second  question  expresses  well 
the  character  of  work  required  for  the  construction  of  a  good  map,  and 
the  deficiency  of  Carrigain's  map  in  this  respect. 

An  accurate  map  of  a  state  is  now  understood  to  imply  a  map  constructed  upon  data 
obtained  by  a  series  of  geodetic  and  astronomical  observations,  carefully  conducted 
with  suitable  instruments  of  the  kind  now  in  use  for  such  work.  Both  instruments 
and  methods  have  been  greatly  improved  within  fifty  years,  so  that  a  degree  of  preci 
sion  is  now  easily  attained  which  was  formerly  impossible.  The  general  method  is 
briefly  this :  A  base  line  of  four  to  ten  miles  in  length  is  accurately  measured,  and 
from  this  a  series  of  large  triangles  is  supposed  to  cover  the  state  like  a  net.  The 
sides  of  these  triangles  should  be  from  twenty  to  forty  miles  long.  The  vertices  of 
these  triangles  are  accurately  determined  in  position  and  elevation  by  the  observations. 
Then  a  series  of  smaller  triangles  are  taken  so  as  to  fix  one  or  two  points  in  or  near 
such  town.  Then  the  town  maps  are  accurately  made  and  put  in  their  true  position  by 
reference  to  the  points  determined  by  the  triangulation.  All  the  Coast  Survey  work  in 
New  Hampshire  is  so  much  work  done,  with  the  requisite  care,  and  the  distance 
between  any  two  of  these  points  can  be  used  for  a  base,  and  the  work  readily  continued 
over  the  state  from  the  points  in  this  state  and  on  the  adjacent  borders  of  Maine  and 
Massachusetts  already  established.  The  measuring  of  a  base  line  with  the  required 
accuracy  is  always  expensive,  and  would  be  particularly  so  in  New  Hampshire.  The 
work  of  the  Coast  Survey  that  could  be  used  without  expense  would  probably  diminish 


TOPOGRAPHICAL    MAPS    OF    THE    STATE.  237 

the  cost  of  the  triangulation  about  one  half.  The  exact  determination  of  the  principal 
points  over  the  state,  in  this  way,  lies  at  the  foundation  of  a  correct  map.  The  town 
maps  and  all  the  details  can  be  prepared  with  more  or  less  fulness  and  correctness,  as 
may  be  convenient,  and  the  state  map  improved  from  time  to  time  till  it  is  perfect,  if 
the  expense  cannot  be  incurred  at  once.  Slight  errors  in  the  position  of  the  details 
would  not  greatly  injure  the  map  if  the  main  points  were  all  correct.  But  a  map 
compiled  from  the  best  town  surveys  could  not  be  relied  upon  as  accurate.  There 
would  be  likely  to  occur  errors  of  some  miles.  In  the  copy  of  Carrigain's  map  now 
before  me,  by  comparing  the  position  of  several  points  with  their  actual  position  as 
determined  by  the  U.  S.  Coast  Survey,  they  appear  to  be  from  ten  to  fifteen  statute  miles 
out  of  the  way  in  longitude,  and  from  one  third  of  a  mile  to  a  mile  in  latitude.  The 
large  error  in  longitude  has  been  partially  corrected  on  later  maps.  The  relative  error 
is  also  considerable,  though  not  more  than  what  might  exist  in  any  map  made  in  the 
same  way.  For  instance,  if  Fort  Constitution  be  assumed  as  correct  in  position, 
Uncanoonuc  is  more  than  a  mile  too  far  north  and  half  a  mile  too  far  east,  while  Mt. 
Washington  is  two  thirds  of  a  mile  too  far  south,  and  one  third  of  a  mile  too  far  west. 
What  remains  to  be  done,  then,  to  obtain  the  required  data  for  an  accurate  map,  is  to 
complete  the  triangulation  of  the  state,  and  make  a  correct  plan  of  all  the  towns  and 
places  that  have  not  yet  been  accurately  surveyed. 

IMPROVEMENTS  INCORPORATED  INTO  THE  NEW  MAP.

accordance  with  the  treaty  of  1842.  Noticed  upon  pages  21,  171.

survey  in  1869.  See  full  report  further  on. 

Triangulation  of  the  geodetic  connection  survey  under  the  direction  of

County  maps.  From  1855  to  1860  careful  odometer  surveys  were 
made  of  every  county  in  the  state,  and  the  results  published  by  subscrip 
tion.  The  scale  was  usually  about  an  inch  to  the  mile ;  and  the  most 
valuable  portions  of  them  relate  to  the  delineation  of  the  highways. 
Existing  surveys  of  lakes,  water-courses,  boundary  lines,  railroads,  and 
other  topographical  features  were  made  use  of  wherever  practicable.  A 
map  constructed  simply  from  these  odometer  maps  would  produce  a  new 
draft  much  superior  to  Carrigain's,  for  the  number  of  surveyors  is  greatly 
reduced,  and  there  is  consequently  less  opportunity  for  discrepancies

twenty  thousand  dollars,  and  their  most  valuable  features  arc  retained  in 
the  new  draft.

no  matter  how  minute.

For  the  delineation  of  mountain  ranges,  use  has  been  made  of  the  facts 
given  in  the  chapter  upon  Altitudes.

*The  geographical  positions  as  given  in  the  earlier  reports  do  not  agree  exactly  with  the  latest  determina 
tions,  especially  of  the  longitudes.  The  ocean  telegraph  has  furnished  the  means  of  ascertaining  more  accurately 
than  before  the  difference  in  time  between  Greenwich  and  Washington.  The  average  correction  to  be  added  to 
the  longitudes  is  20". 15,  and  o".28  to  the  latitudes.  In  the  cases  above,  that  are  marked  with  an  asterisk,  I  have

PROF.  QUIMBY'S  REPORT. 

To  PROF.  C.  H.  HITCHCOCK  :  I  beg  leave  to  submit  the  following 
report  of  the  geodetic  work  done  by  your  order  the  past  year.  I  occu 
pied,  during  the  month  of  October,  1869,  the  following  stations,  and, 
although  the  weather  was  very  unfavorable,  succeeded  in  obtaining  satis 
factory  observations  on  each  :  The  observatory  at  Dartmouth  college  ; 
Moose  mountain,  Hanover ;  Kearsarge,  Warner ;  Uncanoonuc,  Goffstown ; 
Monadnock,  Jaffrey;  and  Ascutney,  Windsor,  Vt.  The  station  upon 
Kearsarge  was  at  an  angle  of  the  line  between  the  towns  of  Warner  and 
Wilmot.

It  is  proper  to  say  that  the  latitude  of  the  Shattuck  observatory,  Dart 
mouth  college,  as  obtained  by  this  survey,  differs  only  2"  from  the  latitude 
as  determined  astronomically  by  Prof.  Young,  and  the  longitude  differs 
only  i".25  from  the  astronomical  longitude  as  far  as  has  been  yet  deter 
mined  ; — and  even  this  discrepancy  is  no  doubt  due  to  the  station  error

of  the  observatory.  The  instrument  used  in  the  survey  was  a  ten-inch 
theodolite  belonging  to  the  Thayer  School  of  Engineering,  Dartmouth 
college.  The  signals  used  were  heliotropes,  which  were  kindly  loaned  for 
this  purpose  by  the  United  States  Coast  Survey. 

Respectfully  submitted,  E.  T.  OUIMBY. 

GEODETIC  CONNECTION  SURVEY. 

DARTMOUTH  COLLEGE,  April  i,  1874. 

DEAR  SIR:  I  am  instructed  by  the  superintendent  of  the  United  States 
Coast  Survey  to  furnish  you  any  information  you  may  desire  from  the 
results  of  the  triangulation  of  New  Hampshire.  It  is  desired  that  you 
state,  in  publishing  these  results,  that  they  are  obtained  by  the  first  rough 
computations,  and  will  doubtless  be  somewhat  modified  by  the  final 
adjustments.  I  have  occupied,  for  observations,  twelve  stations  in  the 
three  seasons  which  have  been  given  to  the  work,  and  observations  have 
been  made  upon  several  hundred  stations.  By  an  appropriation  made 
by  the  state  the  work  has  been  greatly  facilitated  and  extended,  in  the 
establishment  of  tertiary  stations.  The  number  of  geographical  posi 
tions  already  determined  is  fifty,  the  altitudes  of  which  have  also  been 
found  by  trigonometrical  levelling.  Besides  these,  many  others  have  been 
observed  from  one  direction,  and  will  only  require  observing  from  another 
point  to  give  their  latitudes  and  longitudes. 

The  accompanying  chart  shows  the  scheme  of  this  triangulation  and 
the  progress  thus  far,  and  the  former  Coast  Survey  stations  with  which  it 
is  directly  connected.  The  stations  here  shown  are  only  those  occupied 
as  points  of  observation,  the  tertiary  points  being  too  numerous  to  be 
shown  on  a  chart  of  this  size.  The  base  from  which  this  triangula 
tion  proceeds  'is  the  line  Monadnock-Uncanoonuc.  Although  these 
results,  as  above  mentioned,  are  not  to  be  considered  final,  it  may  be 
remarked  that  the  latitude  and  longitude  of  Gunstock,  as  computed 
from  the  base  Monadnock-Uncanoonuc,  through  this  triangulation,  differ 
from  the  former  results  of  the  Coast  Survey  only  oo".O3.  From  this  it 
would  seem  that  the  correction  made  by  the  final  adjustment  will  not  be 
large.  Respectfully  yours,  E.  T.  QUIMBY,

244  PHYSICAL    GEOGRAPHY. 

For  the  sake  of  facilitating  further  determinations,  I  present  also  the 
directions  for  the  selection  of  tertiary  stations.  Persons  who  desire  to 
obtain  the  exact  positions  of  conspicuous  landmarks  in  the  vicinity  of 
Prof.  Quimby's  work,  only  need  to  follow  these  directions,  and  in  due 
time  they  will  receive  the  results  of  the  calculations. 

Directions  for  the  Selection  of  Tertiary  Stations  and  the  Erection  of  Signals  for  the 
United  States  Coast  Survey,  and  the  operations  connected  therewith. 

1 .  Tertiary  stations  should  be  upon  those  hills  which  command  the  best  view  of  the 
surrounding  country,  particularly  within  a  radius  of  six  to  ten  miles.     It  is  not  so 
important  to  secure  a  distant  view  as  that  the  signal  should  be  visible  from  the  valleys 
in  the  more  immediate  vicinity.     It  must  also  be  visible  from  at  least  three  secondary 
stations. 

2.  Having  chosen  the  hill  upon  which  a  signal  is  to  be  erected,  select  that  spot  for 
the  station  where  the  signal  can  best  be  seen  from  all  directions,  taking  care  that  the 
ground  be  as  level  as  possible  for  a  few  feet  around  the  station,  for  the  convenience  of 
placing  an  instrument  over  it. 

3.  The  method  of  marking  permanently  the  station  will  depend  on  the  nature  of  the 
ground.     If  the  ledge  is  within  three  feet  of  the  surface,  remove  the  earth  and  drill  a 
five-eighths  inch  hole  four  inches  deep,  in  which  set  with  lead  or  sulphur  an  iron  bolt 
projecting  three  inches  above  the  ledge.     If  the  ledge  is  near  the  surface,  cut  a  small 
equilateral  triangle  in  the  rock  around  the  bolt  (say  each  side  nine  inches),  one  of  the 
sides  being  north  and  south,  and  the  opposite  vertex  pointing  to  the  east. 

If  there  is  no  ledge  within  three  or  four  feet  of  the  surface,  dig  to  that  depth  and  set 
a  stone  jar  or  some  piece  of  pottery  which  will  accurately  mark  the  station,  and  be 
readily  recognized  when  found.  Pack  the  earth  carefully  around  and  above  this  to  the 
depth  of  twelve  inches,  upon  which  place  a  piece  of  plank  with  a  half-inch  bolt  firmly 
set  in  it  and  projecting  upwards  three  inches  exactly  over  the  station,  as  marked  by  the 
jar. 

4.  Select  for  the  signal  a  straight  pole  (from  which  it  is  better  to  remove  the  bark) 
six  or  eight  inches  in  diameter  at  the  butt,  and  twelve  or  fifteen  feet  long.     Bore  a  hole 
in  the  centre  of  the  butt  to  receive  the  bolt  set  in  the  ledge  or  plank,  and  fasten  to  the 
top  of  the  pole  a  nail  keg,  ten  to  fifteen  inches  in  diameter,  so  that  the  centre  of  keg 
and  pole  shall  coincide.     This  may  most  readily  be  done  by  inverting  the  keg  (one  head 
being  out)  upon  the  pole  and  nailing  through  the  other  head,  at  the  same  time  bracing 
firmly  the  lower  end  of  the  keg.     Cover  this  keg  with  black  cambric,  and  the  pole 
below  the  keg  with  alternate  bands  of  white  and  black.     Set  the  pole  thus  prepared 
over  the  bolt,  and  support  it  in  a  vertical  position  by  filling  around  with  earth,  or  if  on 
a  ledge  by  a  pile  of  stones,  and  also  by  braces  or  wire  guys,  as  the  circumstances  per 
mit  or  require.     Too  great  care  cannot  be  taken  to  place  the  pole  exactly  vertical,  and 
to    secure  it  from   being   moved  by  winds,  cattle,  or   any  other  cause.      To  secure 


TOPOGRAPHICAL    MAPS    OF    THE    STATE.  24$ 

vertically,  use  a  plummet  from  two  directions  at  right  angles,  and  avoid  any  deviation 
of  the  plummet  by  the  wind. 

5.  To  aid  in  finding  the  station  if  the  signal  pole  should  be  removed,  a  full  descrip 
tion  must  be  made,  embracing  the  following  points  : 

The  township  and  county  in  which  it  is  situated  ;  the  most  direct  and  easy  route  for 
reaching  it;,  the  name  by  which  the  hill  is  commonly  known;  the  name  of  the  person 
owning  the  land  where  the  station  is ;  the  name  and  post-office  address  of  the  person 
having  the  signal  in  charge  (who  is  expected  to  restore  it  to  its  proper  position,  if  dis 
turbed)  ;  the  particular  part  of  the  hill  where  it  is  located ;  its  exact  distance  and 
magnetic  direction  from  any  prominent  objects  around ;  the  height  of  the  top  of  the 
keg  above  the  ground ;  the  manner  in  which  the  station  is  marked,  whether  by  bolt  or 
jar ;  and  any  other  statements  which  may  facilitate  the  identification  of  the  spot  when 
ever  the  signal  may  be  destroyed. 

In  this  description  there  should  also  be  noted  the  direction,  by  the  compass,  to  other 
hills  and  mountains  visible,  particularly  to  those  upon  which  signals  have  been  or  are 
to  be  set,  also,  to  church  spires  and  other  prominent  buildings.  This  description 

should  be  carefully  written  out  and  sent  to

MISCELLANEOUS. 

It  is  perhaps  hardly  important  enough  to  mention  reasons  for  choosing 
particular  names  of  localities  when  there  is  opportunity  to  exercise  judg 
ment.  For  example,  in  opposition  to  a  common  usage,  I  employ  Mt. 
Cuba  instead  of  Mt.  Cube,  in  Orford.  According  to  Dr.  Dwight,*  the 
original  name  was  derived  from  the  circumstance  that  a  dog  called  Cuba 
lost  his  life  on  this  eminence  in  a  fight  with  a  bear.  There  is  no  signifi 
cance  in  the  word  Cube,  save  as  a  corruption  of  Cuba.  I  retain  the 
improvement  proposed  by  Carrigain  in  applying  the  appellation  of 
Merrimack  river  to  the  longest  branch  of  the  Pemigewasset.  A  pond  at 
the  north-west  head  of  the  Magalloway  river  we  propose  to  call  Magallo- 
way  pond  or  lake.  Small  bodies  of  water  discovered  in  the  White 
Mountains  are  termed  Haystack  and  Kinsman  ponds.  Mts.  Hale,  Field, 
and  Lyon  are  new  names  suggested  for  peaks  in  Pemigewasset  and 
Northumberland.  Any  other  changes  of  consequence  will  be  noticed  in 
connection  with  descriptions  of  their  geological  or  physical  features. 

The  proper  triangulation  of  the  White  Mountain  district  is  likely  to

246  PHYSICAL    GEOGRAPHY. 

alter  the  dimensions  of  many  tracts  of  land.  The  case  of  Kilkenny  has 
been  referred  to.  Another  is  the  position  of  Mt.  Passaconnaway.  The 
western  line  of  Albany,  as  perambulated,  according  to  James  Shackford, 
lies  west  of  this  mountain ;  but  the  triangulation  will  bring  it  and  White- 
face  into  the  town  of  Waterville.  This  discrepancy  has  not  been 
observed  before.  There  may  be  others  of  a  similar  character.  While 
we  exercise  our  judgment  in  locating  every  point  according  to  our 
information,  we  rejoice  that  our  map  is  not  the  legal  tribunal  for  the 
settlement  of  discrepancies. 

There  are  irregularities  in  the  mutual  boundaries  of  Carroll,  Grafton, 
and  Coos  counties,  which  will  probably  need  rectification  from  the  legis 
lature.  The  limits  are  given  thus  in  the  General  Statutes,  p.  67  : 

Carroll.  "Thence  by  the  northerly  line  of  Sandwich  to  the  westerly 
line  of  Albany  ;  thence  by  the  westerly  line  of  Albany  to  the  north-west 
corner  thereof ;  thence  by  the  north  line  of  Albany  to  the  ivcst  line  of 
Bartlctt ;  thence  by  the  west  lines  of  Bartlctt  and  PI  art  s  Location  to  tlic 
north  line  of  said  Location;  thence  by  the  northerly  and  easterly  lines  of 
said  Location  to  the  west  line  of  Bartlett ;  thence  by  the  westerly  lines 
of  Bartlett  and  Jackson  to  the  northerly  line  of  Jackson,"  etc. 

Grafton.  "Thence  on  the  westerly  and  southerly  lines  of  Dalton, 
Whiten  eld,  Carroll,  and  Nash  &  Sawyer  s  Location,  to  tJic  south-easterly 
corner  thereof;  thence  southerly  on  a  straigJit  line  across  the  nnlocated 
lands  to  the  line  of  the  county  of  Carroll  at  the  nortJi-wcsterly  corner  of 
Albany"  etc. 

Coos  county  "contains  all  the  lands  and  waters  within  the  limits  of  this 
state  which  lie  northerly  of  the  counties  of  Grafton  and  Carroll." 

The  boundaries  as  defined  above  leave  a  triangular  area,  about  half  a 
township  in  size,  outside  all  county  lines.  It  lies  between  the  straight 
easterly  boundary  of  Grafton  and  Hart's  Location.  This  straight  line 
also  cuts  off  a  part  of  Hart's  Location,  making  a  small  area  of  land  to 
lie  in  two  counties.  The  Carroll  county  map  places  the  neglected  area 
and  the  south  projection  of  Coos  county  between  Hart's  Location  and 
Bartlett  with  Jackson,  within  its  own  limits.  Perhaps  this  is  the  best 
disposition  to  be  made  of  these  unsettled  areas,  though  we  can  find  no 
authority  for  such  a  reference.  Any  other  arrangement  lacks  symmetry 
of  outline. 


TOPOGRAPHICAL    MAPS    OF    THE    STATE.  247 

There  is  a  question  in  relation  to  the  proper  boundary  line  between  the  Atkinson  and 
Gilmanton  Academy  and  Carlisle  grants.  The  act  denning  the  former  fixes  the  north 
erly  boundary  on  the  line  of  forty-five  degrees  north  latitude. 

Carlisle's  grant  is  defined  thus :  Commencing  at  east  bank  of  Connecticut  river  at 
point  of  intersection  with  the  north  line  of  the  College  grant  (Clarksville)  ;  "thence 
extending  up  said  river,  on  the  east  side  thereof  as  it  winds  and  turns,  to  the  distance 
of  twelve  miles  in  a  straight  line  from  the  place  of  beginning ;  thence  in  a  line  as 
nearly  as  possible  at  right  angles  with  the  main  course  of  the  aforesaid  line  on  said 
river  to  the  line  of  the  state  of  Maine ;  thence  southerly  by  the  line  of  the  state  of 
Maine  to  a  point  distant  twelve  miles  in  a  right  angular  line  from  the  line  last  aforesaid  ; 
thence  in  a  line  as  nearly  as  possible  at  right  angles  with  the  main  course  of  Connecticut 
river  aforesaid,  and  parallel  with  the  second  line  above  described,  to  the  Connecticut 
river  at  the  place  of  beginning." 

If  these  acts  are  to  be  interpreted  strictly,  there  is  an  irregular  piece  of  land  between 
the  two  grants  which  has  never  been  assigned  to  either  party.  I  have  given  the  line  as 
it  is  usually  understood  by  the  lumbermen. 

Carlisle's  grant  is  divided  into  the  three  townships  of  Carlisle,  Webster,  and  Hub- 
bard,  by  the  proprietors.  As  these  names  appear  upon  the  tax-list  of  Pittsburg,  they 
are  placed  upon  the  map,  though  they  have  never  been  sanctioned  by  the  legislature. 

Our  experience  in  matching  together  the  townships  in  the  northern  part  of  the  state 
makes  it  clear  that  all  the  tracts  of  land  there  are  larger  than  the  bounds  assigned  to 
them  upon  paper.  After  conference  with  engineers  and  map-makers,  I  find  it  to  be  a 
general  rule  that  land  is  always  larger  than  the  original  surveys  allow  it  to  be.  As 
tronomers  allow  a  "personal  equation"  in  their  calculations  from  original  observations  ; 
and,  for  the  same  reason,  terrestrial  boundaries  require  adjustment  after  their  primal 
measurements. 

I  might  mention  other  cases  where  names  and  boundaries  have  been  adjusted  differ 
ently  from  the  previous  maps,  but  do  not  think  them  of  enough  consequence  to  be 
presented  here.  They  all  show  how  desirable  it  would  be  to  have  a  new  map  prepared 
having  all  its  minutiae  settled  by  competent  authority. 


CHAPTER    X. 

ALTITUDES. 

one  would  fashion  a  correct  model  of  New  Hampshire,  he  must 
first  ascertain  the  exact  elevation  of  numerous  points  above  the 
ocean.  As  this  has  been  our  constant  purpose  from  the  very  first,  alti 
tudes  have  been  collected  by  a  study  of  canal  and  railroad  surveys ; 
measurements  have  been  made  with  mercurial  and  aneroid  barometers ; 
and  numerous  profiles  have  been  obtained  by  careful  levelling.  A  multi 
tude  of  observations  have  been  collected,  and  it  is  the  object  of  this 
chapter  to  explain  how  they  have  been  obtained,  and  to  classify  them 
under  various  headings,  such  as  may  be  convenient  for  future  reference. 
If  any  of  our  estimates  are  incorrect,  the  means  of  discovering  the  error 
will  here  be  afforded. 

The  delineation  of  the  geological  sections  across  the  state  has  been 
based  upon  barometrical  measurement,  which  could  be  obtained  with  little 
additional  trouble,  at  the  same  time  with  the  examination  of  strata  and 
the  collection  of  specimens  of  rocks.  This  method  is,  however,  subject 
to  inaccuracies,  owing  to  sudden  fluctuations  in  barometrical  pressure, 
and  other  causes.  The  most  reliable  manner  of  obtaining  extended  series 
of  altitudes  over  a  large  area,  so  as  to  arrive  with  accuracy  at  the  contour 
or  relative  height  and  configuration  of  its  whole  extent,  is  to  combine  this 
inexpensive  barometrical  work,  carried  in  numerous  sections  across  the 
state,  with  transverse  series  of  altitudes  carefully  obtained  with  an 


ALTITUDES.  249 

engineer's  level.  These  being  employed  as  starting-points  for  compara 
tively  short  series  of  barometrical  levels,  the  latter  will  be  perfectly 
reliable,  so  far  as  regards  the  accurate  construction  of  profiles  across  the 
state,  or  the  delineation  of  contour  lines  on  a  map.  For  these  transverse 
series,  railroad  profiles  have  been  employed  whenever  attainable,  together 
with  surveys  for  canals,  water-works,  &c.,  gaps  in  series  being  filled  up, 
and  a  large  amount  of  necessary  extensions  made.  As  part  of  this  work, 
it  will  be  seen  that  a  continuous  series  of  actual  levelling  has  been  per 
formed  under  the  direction  of  the  geological  survey  along  our  entire 
western  boundary  from  Massachusetts  to  Connecticut  lake. 

Exact  information  upon  this  subject,  now  for  the  first  time  obtained 
throughout  the  entire  extent  of  New  Hampshire,  as  here  given  in  tabular 
form,  and  as  presented  to  the  eye  in  the  profiles  of  geological  sections  in 
the  state  museum,  and  which  it  is  intended  to  put  in  a  still  more  practical 
shape  in  a  raised  map  of  New  Hampshire,  may  be  said  to  be  in  many 
respects  of  not  less  importance  than  a  correct  outline  of  the  boundaries 
of  the  state,  with  its  division  into  counties  and  townships.  It  will  be 
readily  seen  that  knowledge  of  this  kind  is  almost  indispensable  to  the 
geologist.  Beyond  this,  when  considered  in  connection  with  geological 
structure  and  proximity  to  the  sea,  the  relative  elevation  of  any  area  is 
the  determining  feature  upon  which  depend  the  character  of  its  climate, 
its  agricultural  products,  its  forest  trees,  the  amount  and  location  of  its 
water-power,  the  facilities  for  communication,  and  the  consequent  distri 
bution  of  population  and  wealth. 

The  different  series  of  altitudes  measured  by  actual  levelling  are  first 
given,  nearly  all  of  which  are  put  in  heavy  type  to  indicate  their  superior 
reliability,  having  been  proved  correct  by  the  agreement  of  results 
obtained  along  different  routes.  In  the  lists  of  altitudes  which  fol 
low'  these,  the  same  heavy  type  designates  such  points  as  belong  to 
these  series,  or  have  otherwise  been  exactly  determined.  Altitudes  given 
in  ordinary  type  have  been  obtained  either  from  levelling, — where  some 
discrepancy  when  connected  with  more  carefully  determined  series  pre 
vents  a  confidence  in  their  entire  correctness, — or,  as  in  the  sections  across 
the  state,  from  barometrical  measurement ; — all  of  these  are  to  be  regarded 
as  closely  approximate. 

This  method  of  printing,  and  the  particular  description  of  the  way  in

250  PHYSICAL    GEOGRAPHY. 

which  these  altitudes  have  been  determined,  with  our  reasons  for  decision 
in  cases  of  disagreement,  will  enable  those  who  have  occasion  to  use  our 
figures  to  do  so  understandingly. 

In  accordance  with  the  example  of  eminent  physicists,  the  standard  to 
which  all  our  altitudes  are  referred  is  the  level  of  the  sea  at  mean  tide. 
Heights  along  railroads,  unless  otherwise  specified,  are  taken  on  top  of 
the  rail  in  front  of  passenger  stations. 

REFERENCE  LINE  FROM   PORTSMOUTH,  THROUGH    CONCORD  AND  WHITE 
RIVER  JUNCTION,  TO  CONNECTICUT  LAKE. 

Several  prominent  lines  of  reference  have  been  determined,  which  have 
served  as  a  basis  for  aneroid  measurements  and  estimates.  The  first 
commenced  with  mean  tide  water  at  Great  bay,  below  the  railroad  bridge 
between  Newmarket  Junction  and  Stratham,  May  2,  1870.  Messrs. 
Frank  and  H.  D.  Woodbridge,  then  members  of  Dartmouth  college, 
levelled  from  here  to  Manchester  depot,  over  the  Concord  &  Portsmouth 
Railroad.  They  found  the  mean  tide  water  to  be  1O.7  feet  below  the 
bottom  of  the  rail.  The  centre  of  Manchester  depot  they  found  to  be 
18O.832  feet  above  this  mean  tide  water. 

The  difference  between  Manchester  and  Concord  depots  was  derived 
from  a  comparison  of  several  measurements,  as  follows  : 

Between  Manchester  depot  and  Hooksett  bridge, 24.565 

Hooksett  bridge  to  Carter's  bridge,  Concord  (J.  A.  Weston),          .         .         4O. 
Carter's  bridge  to  Concord  depot  (railroad  survey),          .         .         .         .  7. 

71.565 

This  places  the  height  of  track  at  Concord  depot  252.397  feet  above 
mean  tide, — i6feet  higher  than  previously  supposed.  The  correctness  of 
this  change  will  appear  by  the  comparison  of  levels  from  this  base  over 
the  Northern  and  Concord  &  Claremont  railroads,  with  lines  of  levels 
from  the  sea  by  way  of  the  Fitchburg  and  Cheshire  railroads,  and  the 
recent  surveys  for  the  Portland  &  Ogdensburg  Railroad.  A  strong  con 
firmation  of  this  is  further  supplied  by  the  Concord  &  Rochester  Rail 
road  survey,  by  Chas.  C.  Lund,  hereafter  given,  the  profiles  of  which 
agree  exactly  with  the  corrected  height  of  Concord. 


ALTITUDES.  251 

Next,  the  very  accurate  surveys  of  the  Northern  Railroad  between 
Concord  and  White  River  Junction,  made  by  A.  M.  Shaw,  were  accepted 
as  correct,  the  difference  between  the  extremes  of  the  road  being  1 16.84O 
feet.  The  height  of  track  at  White  River  Junction  is  thus  placed  at 
389.237.  The  accuracy  of  these  levels  between  Concord  and  White 
River  Junction  is  confirmed  by  the  levels  of  R.  S.  Howe,  engineer  of 
the  Concord  &  Claremont  Railroad,  which  differ  from  those  over  the 
Northern  Railroad  by  only  a  small  fraction  of  a  foot. 

To  obtain  the  remainder  of  this  base  line,  recourse  was  had  to  a  special 
survey  under  A.  F.  Reed,  in  1871,  assisted  by  Dr.  N.  Barrows  of  Mer- 
iden,  and  Messrs.  C  F.  and  F.  A.  Bradley  of  Dartmouth  college.  This 
series  extends  over  the  Connecticut  &  Passumpsic  Railroad  to  Barnet, 
Vt,  at  which  point  it  leaves  the  railroad,  and  follows  the  carriage-road  to 
Connecticut  lake. 

A  line  of  levels  from  the  sea,  connecting  with  this  series  at  Dalton,  is 
furnished  by  the  very  reliable  surveys  for  the  Portland  &  Ogdensburg 
Railroad,  crossing  New  Hampshire  through  the  heart  of  the  White 
Mountains.  The  connection  between  these  series  was  made  for  the  geo 
logical  survey  by  James  T.  Woodbury,  in  February,  1874,  the  levels  of 
the  Portland  &  Ogdensburg  Railroad  survey  being  found  5  feet  higher 
than  those  of  our  series  along  the  Connecticut  river.  This  disagreement 
has  been  in  part  reconciled  by  adding  one  half  the  difference,  viz.,  2\ 
feet,  to  our  former  figures  beyond  Dalton  to  Connecticut  lake. 

Another  series  of  levels,  coincident  with  the  Connecticut  river  line 
from  Groveton  to  North  Stratford,  is  supplied  from  the  surveys  for  the 
Grand  Trunk  Railway.  These  heights  were  given  as  referred  to  tide  at 
Three  Rivers,  P.  Q.  To  make  them  agree  with  our  series  when  changed 
as  just  mentioned,  it  is  necessary  to  call  tide  at  Three  Rivers  30  feet 
above  mean  sea  level, — which  is  quite  near  the  truth, — tide  being  stated 
by  Prof.  Elias  Loomis  to  be  9  feet  at  the  mouth  of  the  St.  Lawrence,  and 
20  feet  at  Quebec,  while  it  is  probably  considerably  higher  at  Three 
Rivers.  Heights  along  this  railroad  have  been  accordingly  referred  to 
mean  sea  level  by  connecting  them  with  our  first  series. 

With  the  modification  mentioned,  Mr.  Reed's  levels  gave  the  difference 
between  the  Junction  and  Connecticut  lake  1,249.626  feet, — the  height 
of  the  lake  being  1,618.863  feet  above  mean  tide.

FROM  SOUTH  ASIIBURNHAM,  MASS.,  THROUGH  BELLOWS  FALLS,  TO 
WHITE  RIVER  JUNCTION. 

A  second  reference  line,  connecting  with  the  one  already  described  at 
White  River  Junction,  was  obtained  from  Boston  by  way  of  Fitchburg 
and  South  Ashburnham,  Mass.  The  height  of  the  railroad  at  the  latter 
place,  as  determined  by  the  Fitchburg  and  Cheshire  Railroad  surveys,  was 
obtained  from  the  records  of  the  Cheshire  Railroad ;  and  the  profile  of 
that  road  was  used  to  Bellows  Falls,  through  the  kindness  of  R.  Stewart, 
superintendent.  From  this  place  the  remaining  distance  to  White  River 
Junction  was  levelled  over  for  the  geological  survey  by  Warren  Upham, 
assisted  by  Benj.  P.  Kelley¥  in  February,  1874.  The  height  of  White 
River  Junction  thus  obtained  was  32  feet  above  that  from  the  former 
series.  In  the  list  of  altitudes  upon  this  series,  all  heights,  from  White 
River  Junction  to  Troy  inclusive,  are  given  to  agree  with  the  previously 
determined  height  of  White  River  Junction,  while  those  south  of  this 
point  agree  with  the  assumed  height  of  South  Ashburnham, — this 
arrangement  being  adopted  because  of  a  slight  discrepancy,  amounting 
to  nearly  this  correction,  found  to  exist  at  that  point  in  the  Cheshire  Rail 
road  profile.  With  the  change  which  would  be  justified  by  a  more  favor 
able  interpretation  of  the  profile  at  this  place,  the  series  from  South 
Ashburnham  gives  White  River  Junction  i£  feet  higher  than  by  the 
series  from  Concord.  Another  survey  over  part  of  this  route,  in  March, 
1874,  by  R.  S.  Howe,  to  connect  his  levels  from  Concord,  over  the  Con 
cord  &  Claremont  Railroad,  with  those  from  the  same  place  over  the 
Northern  Railroad,  proves  by  almost  exact  agreement  the  entire  correct 
ness  of  this  work  north  from  Claremont  Junction. 

Levels  had  been  already  obtained,  under  the  direction  of  the  geological 
survey,  from  South  Vernon  to  Bellows  Falls,  by  Gyles  Merrill,  Jr.,  in  Feb 
ruary,  1873,  and  the  completion  of  this  work  to  White  River  Junction

The  altitudes  comprised  in  these  two  reference  lines  are  arranged  in 
full  under  Nos;  i,  2,  and  3  in  the  tables  of  this  chapter.  The  last  of  these 
contains  the  heights  determined  along  Connecticut  river,  the  reliability  of 
which  is  attested  by  the  close  agreement  of  four  series  directly  from  the 
sea,  viz.,  through  South  Ashburnham,  through  Concord,  and  by  way  of 
the  Portland  &  Ogdensburg  Railroad  and  the  Grand  Trunk  Railway. 

FROM  BOSTON,  BY  WAY  OF  BOSTON  &  MAINE,  PORTSMOUTH,  GREAT  FALLS 
&  CONWAY,  AND  PORTLAND  &  OoDENSBURG  RAILROADS,  TO  DALTON. 

A  third  reference  line,  extending  along  the  eastern  portion  of  the  state, 
and  connecting  with  the  Connecticut  river  series  at  Dalton,  has  been 
obtained  entirely  from  railroad  surveys.  These  altitudes  from  Boston  to 
Great  Falls  were  taken  from  the  original  profile  of  the  Boston  &  Maine 
Railroad,  through  the  kindness  of  Pres.  White,  at  his  office  in  Boston. 
On  this  profile,  reference  was  to  marsh  level  (high  tide),  and  5  feet  have 
been  added  to  the  figures  there  given  for  height  above  mean  tide. 
These  figures  show  an  exact  agreement  at  Newmarket  Junction  with  the 
series  measured  by  the  Messrs.  Woodbridge,  and  again  at  Great  Falls 
with  the  altitudes  furnished  by  T.  Willis  Pratt,  engineer  of  the  Ports 
mouth,  Great  Falls  &  Conway  Railroad,  from  mean  tide  at  Portsmouth. 
By  this  latter  series  the  line  is  continued  to  North  Conway.  The  levels 
for  the  Wolfeborough  Branch,  including  the  altitude  of  Lake  Winnipiseo- 
gee,  were  furnished  by  George  L.  Whitehouse,  Esq.,  of  Farmington,  and 


254  PHYSICAL    GEOGRAPHY. 

by  J.  W.  Levering,  assistant  engineer.  At  North  Conway,  this  series 
connects  with  that  of  the  Portland  &  Ogdensburg  Railroad,  with  which 
it  closely  agrees ;  and  the  remainder  of  this  line,  which  here  turns  north 
westerly,  has  been  supplied  by  John  F.  Anderson,  chief  engineer,  from 
the  surveys  of  that  railroad,  now  being  built  through  the  White  Moun 
tain  notch.  The  whole  line  of  this  road  is  given  from  Portland,  and,  as  the 
reference  of  these  surveys  was  to  mean  low  water  in  Casco  bay,  as  estab 
lished  by  engineers  of  the  U.  S.  C.  S.,  4  feet  have  been  subtracted  from 
the  heights  of  their  profile  given  in  our  annual  report  for  the  year  1871, 
to  reduce  to  mean  tide.  The  connection  between  this  series  at  Dalton 
and  the  line  along  Connecticut  river  has  been  already  mentioned.  It 
will  thus  be  seen  that  the  accuracy  of  this  reference  line  is  confirmed  by 
a  close  agreement  of  altitudes,  obtained  by  five  different  courses  of 
direct  levelling  from  the  sea. 

A  summary  of  prominent  points  along  this  line  is  as  follows  :

ADDITIONAL   RAILROAD  SURVEYS. 

Many  other  extended  series  of  altitudes  have  been  determined  by  the 
various  railroad  surveys  throughout  the  state,  and  wherever  these  have 
been  preserved  and  are  still  attainable,  they  have  been  secured,  and  are 
presented  in  the  tables  following  those  of  the  special  reference  lines  along 
our  east  and  west  borders  already  described.  In  some  instances,  how 
ever,  these  records,  from  various  causes,  have  been  unfortunately  lost. 
On  this  account  it  was  found  necessary,  in  establishing  our  western 
reference  line,  to  level  along  our  whole  western  boundary,  although  rail 
road  lines  extend  over  three  fourths  of  this  distance,  and  were  adopted 


ALTITUDES.  255 

for  our  work  as  affording  the  easiest  route.  For  the  same  reason  it  will 
be  seen  that  we  have  failed  to  present  complete  lists  of  heights  along 
some  other  railroads,  while  in  a  few  cases  no  records  whatever  could  be 
obtained. 

Among  the  railroad  lines  which  we  are  able  to  present  are, — a  survey 
between  Exeter  and  Salisbury,  Mass.;  the  recent  surveys  for  the  Nashua 
&  Rochester  Railroad,  with  points  on  a  survey  from  Windham,  the  junc 
tion  of  this  road  with  the  Manchester  &  Lawrence  Railroad,  to  Lowell ; 
various  points  along  the  Boston,  Lowell  &  Nashua,  Wilton,  and  Peter 
borough  railroads,  with  additional  surveys  extended  from  the  present 
terminus  at  Greenfield  to  the  Connecticut  river  near  Charlestown,  and  a 
few  points  on  a  survey  for  this  road  from  Claremont  village  to  White 
River  Junction;  a  series  of  heights  determined  by  surveys  between 
Rochester  and  Concord;  the  Suncook  Valley  Railroad;  points  on  the 
Manchester  &  North  Weare  Railroad,  and  others  determined  by  surveys 
extended  westward  to  Keene ;  the  very  accurate  surveys  of  the  Concord 
&  Claremont  Railroad,  with  the  Hillsborough  Branch  ;  and  the  Boston, 
Concord  &  Montreal  Railroad.  These  various  surveys  have  been  tabu- 
larly  arranged  in  the  above  order,  exhibiting  several  accurately  measured 
transverse  sections  of  the  state,  while,  by  the  last,  a  longitudinal  series  is 
furnished  from  Lake  Winnipiseogee  to  Lancaster.  Other  altitudes  have 
been  gathered  from  railroad  surveys  not  here  mentioned.  In  all  cases 
the  name  of  the  surveyor,  or  the  source  from  which  information  has  been 
obtained,  is  given,  with  any  explanation  which  could  add  to  its  practical 
value. 

MISCELLANEOUS  ALTITUDES. 

Other  accurately  determined  altitudes  have  been  collected  from 
different  sources.  A  considerable  number  of  these,  in  the  vicinity  of 
our  cities,  are  from  the  surveys  for  water-works.  Others  are  from  sur 
veys  for  canals,  or  for  manufacturing  companies,  by  which  heights  along 
the  rivers  have  been  obtained,  with  the  amount  and  extent  of  many  of 
the  most  important  falls.  Where  such  information  has  not  been  attain 
able,  the  height  of  our  largest  rivers  has  been  stated  approximately. 
These  altitudes  are  not  presented  here  in  full,  as  they  would  to  a  large 
extent  require  repetition  in  another  chapter,  treating  of  our  water-power. 


256  PHYSICAL    GEOGRAPHY. 

They  will  be  found  there,  arranged  in  the  description  of  river  systems, 
together  with  heights  of  the  principal  lakes  and  ponds  of  the  state,  and 
others  along  lines  of  water-sheds,  many  of  which,  taken  from  baromet 
rical  measurement,  are  not  to  be  regarded  as  exact. 

The  altitudes  of  principal  points  along  the  main  water-shed  of  New 
Hampshire,  separating  the  waters  of  the  Connecticut  from  those  of  the 
Androscoggin,  Saco,  and  Merrimack,  being  of  the  first  importance  as 
illustrating  the  topography  of  the  state,  have  been  already  given  in  a  pre 
ceding  chapter.  Also,  in  the  same  chapter,  are  to  be  found  heights  along 
the  boundaries  of  New  Hampshire. 

The  lists  of  altitudes  of  villages,  of  some  of  the  largest  lakes  and 
ponds,  of  the  largest  rivers  at  a  few  places,  and  of  other  points  of  inter 
est  throughout  the  state,  have  been  derived  from  various  sources,  the 
degree  of  probable  accuracy  being  indicated  by  the  difference  in  type. 

The  table  of  heights  of  the  mountains  and  principal  hills  of  the  state, 
with  miscellaneous  points  in  the  mountain  region,  comes,  to  a  large  extent, 
from  barometrical  measurement.  Others,  both  in  this  list  and  in  that  of 
villages,  &c.,  have  been  copied  from  different  publications,  in  which  case 
the  original  authority  is  usually  given,  exact  measurements  being  distin 
guished  by  heavy  type.  A  very  valuable  list  of  altitudes,  principally  of 
mountains  and  hills,  has  been  obtained,  in  connection  with  the  triangula- 
tion  of  the  state  under  the  U.  S.  Coast  Survey,  by  Prof.  E.  T.  Quimby ; 
these,  so  far  as  the  survey  has  been  already  extended,  are  given  on  p.  242. 

GEOLOGICAL  SECTIONS. 

Fourteen  general  sections  have  been  measured,  extending  across  the 
state  in  parallel  lines,  nearly  east  and  west.  Their  geological  character 
will  be  given  subsequently ;  but  it  is  the  proper  place  here  to  state  what 
figures  have  been  used  in  drawing  their  profiles,  as  exhibited  in  connec 
tion  with  the  rock  specimens  in  the  state  museum  at  Hanover.  Exact 
determination  by  levelling  has  been  secured  for  the  starting-point 
wherever  practicable,  and  the  aneroid  barometer  has  been  employed  for 
determining  heights  beyond.  The  details  cannot  very  well  be  presented 
with  each  determination,  as  they  are  too  voluminous,  and  not  of  great 
consequence. 

The  names  of  residents,  streams,  hills,  and  mountains  are  taken  from 


ALTITUDES.  257 

the  several  county  maps.  Exceptions  to  this  rule  may  occur.  Our  inten 
tion  is  to  have  the  names  conform  to  those  adopted  upon  our  geological 
map.  The  most  important  deviations  from  the  usage  of  the  county 
maps  have  been  explained  in  Chapter  IX. 

The  results  of  the  numerous  railroad  and  special  surveys  here  ex 
hibited,  together  make  up  a  complete  network  of  interlocking  series  of 
accurately  determined  altitudes  throughout  the  entire  state.  With  this 
as  a  basis  of  reference,  it  is  believed  that  the  barometrical  measurements 
of  the  altitudes  of  villages  and  of  general  sections  will  be  found  of  the 
highest  value,  in  an  inquiry  into  the  geology,  climate,  and  physical  char 
acter  of  New  Hampshire.

The  records  of  this  road  having  been  lost  by  fire,  the  altitudes  published  in  Guyot's 
Memoir  on  the  "Appalachian  Mountain  System," which  were  derived  from  the  original

records,  are  here  given,  with  others  from  a  published  plan  and  profile  of  a  survey  for 
this  road  between  WoodsviUe  and  Lancaster,  by  J.  L.  Gregg,  engineer,  in  1849. 
These  altitudes  are  known  to  be  approximately  in  agreement  with  other  series  fore 
going,  by  comparison  at  Lake  Winnipiseogee,  at  Wells  River,  and  at  the  junction  of 
the  Mt.  Washington  Branch  with  the  P.  &  O.  Railroad.  Several  heights  in  the 
vicinity  of  Bethlehem,  and  others  from  the  recent  surveys  north  from  Littleton  and 
for  the  Mt.  W.  Branch,  have  been  furnished  by  engineers  H.  W.  Goodrich  and  R.  S. 
Howe.

noticed  (p.  251).  This  profile  thus  referred  to  sea  level  indicates  for  Gorham  a 
height  10  feet  greater  than  that  given  for  this  railroad  station  by  Guyot,  from  which 
base  his  determinations  of  altitudes  among  the  White  Mountaias  were  probably

We  are  now  prepared  to  make  a  practical  application  of  the  long  list 
of  heights  given  with  so  much  particularity.  By  noting  their  relations 
to  the  rise  and  fall  of  land,  one  can  designate  certain  points  where  the 
land  must  be  of  a  given  height.  Furthermore,  after  fastening  upon  a 


ALTITUDES.  2QI 

multitude  of  points  which  seem  to  be  exactly  500  feet  above  mean  tide, 
we  may  connect  them  together  by  lines,  and  thus  indicate  the  level  of 
500  feet  wherever  it  may  extend  throughout  the  state.  If  it  were  possi 
ble  to  lay  down  a  red  cord  from  town  to  town,  wherever  this  contour  line 
extended,  the  means  would  be  afforded  for  determining  the  exact  height 
of  much  territory.  The  next  best  thing  is  to  draw  the  course  of  the  line 
upon  a  map.  By  drawing  a  series  of  them  and  coloring  the  areas  between, 
one  can  get  at  a  glance  the  relative  elevations  of  all  parts  of  the  state. 
If  skilfully  prepared,  such  a  map  is  invaluable. 

We  have  endeavored  to  prepare  such  a  chart,  and  present  it  in  the 
atlas.  The  final  sketch  is  not  drawn  at  the  moment  of  penning  this 
description,  but  a  general  idea  of  its  appearance  will  lead  those  interested 
to  examine  it  in  detail  for  themselves.  We  desire,  also,  to  incorporate 
other  facts  which  may  still  be  within  our  reach  before  the  final  comple 
tion  of  our  work.  Such  a  sketch  may  be  elaborated  indefinitely.  Our 
aim  is  to  make  use  of  a  well  engraved  map  of  the  state  on  copper,  on 
the  scale  of  eight  miles  to  the  inch,  and  draw  upon  it  the  contour  lines 
for  every  successive  five  hundred  feet  of  altitude.  Twelve  of  them, 
therefore,  can  be  represented  within  the  state  limits. 

TJic  $oo-fcet  Line.  This  commences  at  Lake  Newichwannock,  between 
Wakefield,  and  Newfield  and  Acton,  Me.,  the  sources  of  Salmon  river, 
and  the  south  end  of  the  straight  east  boundary.  The  line  runs  south 
westerly  into  Milton,  curving  around  parallel  to  the  Portsmouth,  Great 
Falls  &  Conway  Railroad  to  Union  Village,  on  the  east  side  of  the  Fel 
lows  Branch  river  valley.  It  then  follows  the  west  border  of  the  same 
valley  into  Farmington,  returning  northerly  along  the  Dover  &  Win- 
nipiseogee  Railroad  into  New  Durham.  The  line  apparently  follows 
back  the  other  side  of  the  Cochecho  valley  into  Rochester,  and  turns  up 
the  Isinglass  river  and  its  branches,  to  within  half  a  mile  of  Bow  lake 
in  Strafford.  The  line  next  passes  more  westerly  from  Barrington  into 
Nottingham,  Deerfield,  and  Candia,  almost  connecting  with  its  course  up 
the  Suncook  valley  through  Deerfield.  From  the  west  part  of  Candia  it 
passes  along  the  ridge  east  of  Manchester,  within  two  miles  of  Massa- 
besic  lake.  Thence  it  doubles  back  in  sight  of  the  city  of  Manchester, 
and  passes  up  the  valley  of  Suncook  river  to  Pittsfield,  extending  nearly 
to  Suncook  pond,  or  the  tributary  from  Northwood.  Thus  nearly  all  of 


292  PHYSICAL    GEOGRAPHY. 

Rockingham  county  lies  below  the  level  of  500  feet.  There  must  be 
several  islands,  or  insulated  areas  of  land,  above  500  feet  to  the  south  of 
the  line  as  described. 

From  Pittsfield  the  line  extends  to  the  lower  part  of  Chichester,  and 
curves  back  north-easterly  along  the  Soucook  valley  to  the  north  part  of 
Loudon.  It  then  passes  directly  to  Winnipiseogee  lake,  after  curving 
nearly  to  the  town  of  Concord,  through  Canterbury,  Northfield,  Belmont, 
and  Gilford.  The  shore  of  Lake  Winnipiseogee  affords  the  most  accu 
rate  notion  of  the  course  of  our  line  in  Belknap  and  Carroll  counties, 
since  the  average  height  of  the  lake  is  just  500  feet.  Returning  down 
the  valley,  there  is  a  great  curve  northwardly  into  Meredith,  for  the  Win- 
nisquam  lake,  thence  the  course  is  through  Tilton  and  Sanbornton, 
crowding  the  Merrimack  river  opposite  Bristol,  and  bordering  the  river 
into  Campton  and  Rumney,  the  area  between  the  lines  varying  some 
what  in  width. 

On  the  west  side  of  the  Merrimack  the  return  line  cannot  pass  the 
barrier  till  we  reach  the  edge  of  Concord.  It  then  passes  up  the  Black- 
water  valley  into  Salisbury.  The  line  passes  up  to  Warner  on  Warner 
river,  and  to  Hillsborough  on  the  Contoocook  river.  Rattlesnake  hill,  in 
Concord,  becomes  an  island.  From  opposite  the  Mast  Yard,  in  Concord, 
the  line  crosses  to  the  Bow  hills,  turning  in  Hooksett  and  Goffstown  to 
pass  up  to  North  Weare  along  the  Piscataquog,  with  a  branch  to  New 
Boston.  The  line  returns  through  Bedford,  and  extends  up  the  Quoh- 
quinapassakessananagnog  creek  into  Amherst.  On  the  Souhegan  river 
the  line  may  extend  into  the  edge  of  Lyndeborough.  The  banks  on  this 
river  through  Wilton  are  high,  and  not  far  apart,  so  that  the  area  below 
the  level  of  500  feet  is  long  and  narrow.  The  line  seems  to  leave  the 
state  in  the  south-west  corner  of  Brookline. 

The  line  next  enters  the  state  in  Winchester  along  the  Connecticut 
valley,  and  extends  to  the  Fifteen-miles  falls  in  Monroe,  curving  north 
easterly  along  the  valleys  of  the  tributaries.  On  the  Ashuelot,  the  line 
extends  a  little  ways  above  Keene.  As  the  water-shed  between  the 
Ashuelot  and  Connecticut  rivers  continues  to  the  village  of  Hinsdale  as 
a  prominent  ridge,  the  area  below  five  hundred  feet  is  very  marked  on  the 
map  in  the  former  valley.  On  Cold  river,  the  line  runs  up  to  the  edge  of 
Acworth ;  on  Sugar  river,  nearly  to  Claremont  village ;  on  Mascomy  river, 


ALTITUDES.  2Q3 

to  Lebanon  village ;  and  only  a  short  distance  up  the  other  tributaries. 
It  passes  up  the  Passumpsic  river  five  or  six  miles. 

The  5oo-feet  line  passes  a  few  miles  into  New  Hampshire  along  the 
Ossipee  and  Saco  valleys.  The  two  contours  almost  connect  on  the  Mad 
ison  summit  of  the  Portsmouth,  Great  Falls  &  Conway  Railroad,  and,  on 
the  Saco,  the  line  passes  to  Lower  Bartlett. 

The  looo-fcet  line.  On  the  Androscoggin  this  line  extends  to  the  top 
of  Berlin  falls,  and  to  the  west  line  of  Gorham  on  Moose  river.  On  the 
Saco  it  reaches  to  the  mouth  of  Nancy's  brook,  near  the  residence  of  Dr. 
S.  A.  Bemis,  also  two  or  three  miles  up  Sawyer's  river,  and  above  Jackson 
on  the  Ellis  river.  On  Swift  river  it  extends  to  the  west  part  of  Albany. 
It  then  follows  the  foot  hills  of  the  White  Mountains  to  the  junction  of 
the  main  branches  of  the  Pemigewasset  river  at  North  Woodstock,  having 
run  two  or  three  miles  into  Waterville  along  Mad  river.  The  line  from 
the  Pemigewasset  passes  into  the  valley  of  Baker's  river  to  the  north  part 
of  Warren,  returning  on  the  west  side  to  Bridgewater,  thence  curves 
around  Newfound  lake,  and  can  be  traced  to  the  valley  of  Smith  river, 
whence  it  passes  to  the  highest  summit  on  the  Northern  Railroad  in 
Orange.  The  railroad  has  been  excavated  beneath  the  thousand-feet  level 
at  this  divide ;  but  there  are  a  few  rods'  width  of  the  natural  surface  of 
the  ground  which  rise  above  that  level.  The  line  next  passes  in  a  south 
erly  direction  to  Massachusetts,  curving  very  much  easterly  to  pass 
around  Mt.  Kearsarge,  returning  to  the  railroad  summit  in  Newbury,  and 
reaching  the  towns  of  Jaffrey  and  Sharon  on  the  Contoocook  river  before 
coming  back  to  Deering  and  Weare  on  the  east  side  of  the  same  valley. 
The  line  leaves  the  state  in  New  Ipswich. 

The  most  prominent  islands  to  the  south-east  of  the  line  just  described 
are  the  Eaton-Madison  heights,  Ossipee  Mountain  group,  Green  moun 
tains  in  Effingham,  the  mountains  between  Strafford  and  Carroll  counties, 
the  Gunstock  and  Belknap  range,  Red  hill,  New  Hampton  and  Sanborn- 
ton  heights,  Ragged  mountains  in  Hill  and  Andover,  and  the  Uncanoonucs 
in  Goffstown. 

On  the  west  side  of  the  Merrimack-Connecticut  water-shed  we  find  the 
area  between  the  mill-pond  and  Troy,  on  the  Cheshire  Railroad,  to  be 
above  one  thousand  feet,  the  line  curving  westerly  from  the  south  part  of 
Fitzwilliam  around  Richmond  to  Troy.  Thence  it  proceeds  nearly  to 


294  PHYSICAL    GEOGRAPHY. 

Harrisville,  thence  into  Marlow,  around  most  of  Alsteacl,  and  up  the 
valley  of  Cold  river  into  Lempster.  The  line  returns  so  as  to  pass  south 
of  Acworth  village,  thence  northerly,  and  north-easterly  irregularly,  nearly 
to  Sunapee  lake.  The  line  now  runs  back  among  the  hills  on  the  north 
branches  of  Sugar  river,  even  into  Springfield,  but  meanders  back  to 
Claremont,  and  then  passes  northerly  on  the  flanks  of  Croydon  and 
Grantham  mountains  to  East  Lebanon,  thence  southerly  to  the  Orange 
railroad  summit,  thence  to  the  north  line  of  Canaan,  and  westerly  nearly 
to  the  gap  between  Moose  and  Smart's  mountains,  thence  southerly  to 
the  south  end  of  Moose  mountain,  and  thence  northerly  to  the  Swift 
Water  valley  in  Haverhill.  Thence  the  line  passes  south-easterly  towards 
the  Woodstock  notch,  and  thence  irregularly  to  Franconia  iron  works,  to 
North  Lisbon,  and  up  the  Ammonoosuc  river  nearly  to  the  Wing  Road 
station.  The  Whitefield  summit  (Boston,  Concord  &  Montreal  Railroad) 
lies  above  one  thousand  feet ;  and,  therefore,  this  contour  returns  to  Little 
ton,  passes  around  Palmer  hill,  and  thence  into  Whitefield  through  Dalton. 
From  the  very  bank  of  the  Connecticut  in  South  Lancaster  the  line  runs 
into  Lancaster,  Northumberland,  around  Mt.  Lyon,  and  up  the  Grand 
Trunk  Railway  into  Stark  and  Milan.  Returning,  the  line  extends  up  the 
Connecticut  to  Columbia,  and  up  Nulhegan  river  in  Vermont  two  or  three 
miles.  Gardner's  Mountain  range  in  Lyman  is  the  principal  island  west 
of  this  looo-feet  level  on  the  Connecticut  slope. 

The  i^oo-fcet  line.  In  the  south  part  of  the  state  this  line  appears 
chiefly  along  the  Merrimack-Connecticut  water-shed,  as  a  series  of 
islands.  First  there  are  the  Barrett,  Pack  Monadnock,  and  Monadnock 
series.  Next,  the  heights  in  Nelson,  Stoddard,  Springfield,  and  the 
Sunapee  range.  On  the  east  Mt.  Kearsarge,  and  on  the  west  Croydon, 
Grantham,  Moose,  Smart,  Cuba,  and  Piermont  mountains,  reach  above 
this  line.  Other  areas  are  connected  with  the  Cardigan  range,  Groton 
and  Plymouth  heights,  Gunstock,  Ossipee,  and  Green  mountains. 
Another  prominent  expanse  above  1500  feet  lies  east  of  Baker's  river, 
in  Wentworth,  Warren,  and  Rumney. 

The  entire  White  Mountain  area  is  encircled  by  this  contour  line,  with 
very  narrow  strips  of  a  lower  level,  marking  off  Pequawket  and  the  Starr 
King  group.  There  are  two  areas  to  the  north  above  this  line,  one  cast 
of  the  Androscoggin  valley,  and  the  other  north  of  the  Grand  Trunk 


ALTITUDES.  2Q5 

Railway.  This  line  is  reached  on  the  Connecticut,  near  the  "hollow," 
six  miles  below  the  lake. 

Contours  from  2,000  to  6,000  feet  JiigJi.  These  are  confined  to  com 
paratively  small  areas,  and  need  not  be  described  fully  in  the  text.  Only 
two  mountains,  Monadnock  and  Cardigan,  south  of  the  Boston,  Concord 
&  Montreal  Railroad,  exceed  3,000  feet,  while  Kearsarge  and  Cuba  are 
nearly  as  high.  In  the  same  district  the  following  exceed  2,000  feet : 
Bald,  Pack  Monadnock,  Crotched,  Pitcher,  Croydon,  Melvin,  Sunapee, 
Ragged,  Lovell's,  Moose,  Smart's,  Piermont,  Webster  slide,  and  Mist. 
Near  Winnipiseogee  lake,  Gunstock,  Belknap,  Ossipee,  Green,  Cropple 
Crown,  Red  Hill,  Prospect,  Israel,  and  Squam  exceed  the  same  figure. 
Nearly  all  the  White  Mountain  elevations  are  more  than  2,000  feet  high. 

North  of  the  Grand  Trunk  Railway  the  following  peaks  exceed  2,000 
feet :  Ingalls,  Half-moon,  Dustan,  Hampshire  hills,  Pisgah,  Lyon,  Percy 
peaks,  Stratford  mountains,  Dixville  range,  peaks  in  Millsfield,  Stewarts- 
town,  Atkinson  and  Gilmanton  Academy  grant,  Webster,  Mt.  Carmel, 
and  the  highland  boundary. 

The  special  arrangement  of  the  elevated  contours  about  the  White 
Mountains  can  be  best  understood  by  reference  to  the  maps  in  the  atlas. 
Washington  is  the  only  peak  exceeding  6,000  feet.  Eight  are  more  than 
5,000  feet  high,  viz.,  Adams,  Jefferson,  Clay,  two  Monroes,  Madison,  La 
fayette,  and  Lincoln.  Fourteen  equal  or  exceed  4,500  feet,  viz.,  Franklin, 
Pleasant,  two  Carters,  Moriah,  Carrigain,  Moosilauke,  Flume,  Liberty, 
south  peak  of  Lafayette  range,  four  of  Twin  Mountain  range,  and  perhaps 
others.  Twenty  equal  or  exceed  4,000  feet,  viz.,  two  Whitefaces,  Passa- 
connaway,  four  of  the  Tripyramid,  Osceola, — Sandwich  Dome  lacks  only 
one  foot  of  it, — Hancock,  Willey,  Field,  one  between  Nancy  and  Lowell, 
highest  peak  of  Willey  chain,  Kinsman,  Blue,  Wild-cat,  Webster,  Jackson, 
Clinton,  and  perhaps  others.  Twenty-eight  equal  or  exceed  3,000  feet, 
viz.,  Crawford,  Resolution,  Giant's  stairs,  Tri-mountain,  Silver  spring, 
Table,  Chocorua,  Pequawket,  Baldface,  Doublehead,  Mote,  Welch,  Echo, 
Profile,  Black  (Warren),  Kineo,  Cushman,  Waternomee,  Carr,  Bear, 
Lowell,  Nancy,  Randolph,  South,  Long,  Starr  King,  Pilot,  Cherry,  and 
others  unnamed.  Those  above  2,000  feet  are  still  more  numerous. 

Conclusions.  From  the  presentation  of  the  above  facts,  we  may  per 
ceive  that  the  land  rises  in  passing  north-westerly  from  the  coast  till  the 


296  PHYSICAL    GEOGRAPHY. 

main  ridge  or  backbone  of  the  state,  described  on  page  210,  is  reached, 
averaging  about  twenty  miles  distant  from  Connecticut  river.  On  the 
west  of  this  ridge  there  is  a  gradual  rise  along  the  western  boundary  from 
two  hundred  to  three  thousand  feet,  or  so  that  the  head  of  the  valley 
reaches  the  level  of  the  summit  ridge  on  the  north  border.  The  culmi 
nating  point  in  the  ridge  is  about  one  third  of  the  way  from  the  north 
boundary. 

The  following  may  show  the  general  arrangement  of  the  several  areas : 
The  south-east  corner, — making,  with  the  narrow  Connecticut  strip,  about 
one  sixth  of  the  whole  area  of  the  state, — lies  altogether  below  500  feet. 
The  1000  to  i5OO-feet  area,  occupying  about  a  fifth  part  of  our  territory, 
is  situated  mainly  along  the  Connecticut-Merrimack  ridge,  skirting  the 
White  Mountains  on  the  east,  and  then  passing  up  the  Androscoggin 
valley  to  Umbagog  lake.  The  500  to  moo-feet  line  embraces  certainly 
two  fifths  of  our  area,  and  lies  chiefly  between  the  south-east  5 co-feet  line 
and  the  Connecticut-Merrimack  ridge, — the  balance  occupying  the  western 
slope  of  the  state.  About  one  sixth  of  our  area  reaches  above  2000  feet ; 
and  the  balance  would  be  occupied  by  the  1 5 oo-2OOO-feet  surface.  This 
would  place  the  average  elevation  of  the  state  above  the  sea  at  about 
fourteen  hundred  feet. 

With  the  exception  of  about  one  twelfth  part  of  our  territory,  every 
thing  is  susceptible  of  cultivation.  There  is  good  grass  land  in  Stoddard 
2 1 70  feet  above  the  sea,  and  perhaps  higher,  north  of  Colebrook.  Forest 
trees  grow  to  advantage  to  the  height  of  3000  feet  among  the  White 
Mountains,  and  will  flourish  a  thousand  feet  higher  if  protected  from  the 
stronger  winds.  At  4000  feet  the  animals  and  plants  common  in  Green 
land  and  Labrador  begin  to  show  themselves,  and  they  extend  universally 
above  that  level.  In  subsequent  chapters  the  geographical  distribution 
of  animals  and  plants  will  be  taken  up  in  considerable  detail. 

NOTE.  For  the  sake  of  perfecting  the  tables  of  heights,  I  have  sent  proof-sheets  of  this  chapter  to  several 
gentlemen,  and  can  report  from  their  examinations  a  few  corrections  on  what  has  preceded. 

Prof.  Quimby  reports,  upon  reexamining  his  note  books,  that  118  feet  should  be  added  to  the  height  of  the 
Shaker  barn,  Canterbury  (see  pp.  242,  277) ;  and  that  28  feet  should  be  added  to  the  height  of  North  Putney  hill, 
Hopkinton  (see  pp.  242,  280).  The  heights  of  Mts.  Moose  and  Cuba,  when  calculated  from  Observatory  hill, 
Hanover,  "  come  out  within  ten  or  fifteen  feet"  of  what  they  are  given  on  page  242.  All  these  altitudes  on  page 
242  have  been  reduced  from  the  original  figures  given  to  us,  to  agree  with  the  known  heights  of  Kearsarge 
and  the  state  house,  by  subtracting  55  feet.  This  has  not  been  done  in  the  case  of  Mts.  Pequawket  and  Pleasant 
(p.  280),  the  figures  being  given  as  stated  in  the  published  Coast  Survey  reports. 


ALTITUDES. 


297 


Many  persons  may  desire  that  these  altitudes  should  have  been  much  more  numerous.  Others  might  have 
been  given,  but  i  did  not  think  it  desirable  further  to  encroach  upon  the  text,  especially  as  the  contour  map  will 
give  a  general  idea  of  the  altitude  of  every  foot  of  land  in  the  state. 

I  should  have  been  glad  to  reproduce  Prof.  (Juyot's  figures,  as  obtained  by  the  mercurial  barometer,  for 
comparison  with  those  of  the  Geodetic  Connection  survey.  It  has  been  done  only  in  a  few  cases  on  page  280. 
His  barometrical  figures  are  usually  nearly  as  reliable  as  those  obtained  by  the  measurement  of  vertical  angles. 
I  have  altered  his  figures  of  the  heights  of  mountains  in  Warren,  page  281,  measured  on  the  slope  of  Moosilauke 
with  a  pocket  level,  and  communicated  privately  to  William  Little,  by  the  difference  between  the  barometrical 
and  trigonometrical  heights  of  Moosilauke.  I  have  been  disappointed  in  not  receiving  from  Prof.  Guyot  answers 
to  several  questions  about  his  measurements,  sent  with  the  proofs  of  this  chapter.  Hence  the  reference  to  "  note 
beyond,"  on  page  275,  has  no  significance. 

R.  S.  Howe,  engineer  of  the  Northern  Railroad,  suggests  the  addition  of  the  following  statement  to  the  end 
of  the  second  paragraph  on  page  249 :  "  and  an  efficient  means  of  noticing  the  orographical  and  other  physical 
peculiarities  of  the  state,  and  placing  within  reach  of  the  medical  profession  a  record  that  may  enable  and  induce 
professional  men  in  different  localities  to  observe,  record,  and  contrast  the  Influence  of  elevation,  if  it  has  any,  on 
health  and  disease.  Hitherto,  latitude  and  longitude  have  been  the  chief  and  almost  the  only  conditions  modify 
ing  climate  that  have  been  taken  into  account  in  considering  the  influences  on  health ;  but  the  observations  of 
physicians  and  travellers  present  facts  suggesting  that  altitude,  to  some  extent,  controls  the  type  of  diseases."

CHAPTER    XL 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE. 


BY   WARREN   UPHAM. 


the  entire  area  of  New  Hampshire  it  is  estimated  that  one  sixth 
part  is  covered  with  water.  Fifteen  hundred  streams  are  delineated 
on  the  various  county  and  other  maps ;  and  numerous  lakes  and  ponds 
are  scattered  over  the  entire  state.  The  object  of  this  chapter  will  be  to 
present  a  description  of  our  different  hydrographic  divisions ;  and  to  con 
sider  the  influence  of  the  position,  physical  features,  and  climate  of  our 
state  upon  the  distribution  and  character  of  its  rivers  and  lakes. 

New  Hampshire  is  divided  into  five  hydrographic  districts,  which  are 
drained  by  the  Connecticut,  Merrimack,  Androscoggin,  Saco,  and  Piscat- 
aqua  rivers.  None  of  these  river  systems  is  wholly  comprised  within  the 
limits  of  the  state.  The  description  of  these  districts  should  embrace 
both  the  principal  river,  with  tributaries  and  lakes,  and  also  the  area 
drained,  or  river  basin.  Of  the  rivers,  the  features  which  require  notice 
are  the  direction  and  extent  of  their  course,  their  volume,  and  their  slope 
or  rapidity  of  descent.  Of  the  drainage  basins,  the  particulars  to  be 
noted  are  position,  area,  elevation,  and  proportion  of  surface  covered  by 
forest.  The  relations  of  rain-fall  and  temperature,  being  nearly  uniform 
in  the  different  portions  of  the  state,  are  left  to  be  considered  with  the 
other  general  conditions  on  which  the  hydrographic  character  of  the 
state  depends. 


RIVER  SYSTEMS  OF  NEW  HAMPSHIRE.  299 

BOUNDARIES  OF  HYDROGRAPIIIC  BASINS. 

Connecticut  River.  The  main  water-shed  of  the  state,  separating  the 
waters  of  the  Connecticut  from  those  of  the  Androscoggin,  Saco,  and 
Merrimack,  commences  at  the  Canadian  boundary  five  miles  south-west 
of  Crown  monument,  and  three  miles  east  of  Third  "lake.*  Its  course  is 
first  south-east  to  Mts.  Abbott  and  Carmel,  thence  south-west  nearly  to 
the  southern  border  of  Second  lake,  thence  south  to  Magalloway  moun 
tain,  and  then  south-west  to  Mt.  Pisgah.  It  next  bends  more  to  the  west, 
and  reaches  its  farthest  limit  just  west  of  the  Diamond  ponds  in  the 
eastern  part  of  Stewartstown ;  thence  it  runs  south-east  to  Dixville  notch, 
thence  a  little  east  of  south,  through  Millsfield,  Dummer,  and  Milan,  to  a 
point  about  three  miles  north-west  of  Berlin  falls.  Here  it  bends  to  the 
south-west,  passing  along  the  mountain  ridges  in  Randolph,  then  south 
east  to  Mts.  Jefferson  and  Washington,  then  south-west  along  this  range 
to  Mt.  Clinton  and  the  Notch.  Thence  it  extends  nearly  west  over  the 
Twin  mountains  and  Lafayette  to  Cannon  mountain  in  Franconia ;  thence 
it  turns  south-west,  passing  over  Mt.  Kinsman,  through  the  west  part  of 
Lincoln  and  near  the  boundary  between  Woodstock  and  Benton,  to 
Moosilauke,  from  which  it  descends  to  the  Oliverian  notch  in  the  north 
part  of  Warren.  It  then  passes  to  the  mountains  in  the  north-west  corner 
of  this  township,  and  thence  south-westerly  over  Ore  hill  and  through  the 
south-east  corner  of  Piermont  to  Mt.  Cuba  in  the  east  part  of  Orford. 
From  this  it  extends  south-east  to  Cardigan  mountain  in  Orange,  dividing 
Dorchester  by  a  diagonal  line.  It  next  turns  south-west  to  Orange  sum 
mit,  on  the  Northern  Railroad ;  thence  it  extends  nearly  south  through 
the  west  part  of  Grafton  and  the  north-east  part  of  Springfield,  passing 
into  New  London  between  Little  Sunapee  lake  and  Pleasant  pond,  thence 
bending  south-west  to  within  a  half  mile  of  Sunapee  lake  at  its  north 
east  extremity.  This  line  next  passes  over  the  high  ridge  in  the  north 
west  corner  of  Sutton,  thence  south-west  into  Newbury,  again  coming 
within  about  a  half  mile  of  Sunapee  lake  at  its  southern  end,  and  thence 
west  to  Sunapee  mountain.  From  this  the  water-shed  line  follows  the 
highlands,  which  extend  south,  nearly  through  the  centres  of  Washington, 
Stoddard,  Nelson,  and  Dublin,  to  Monadnock  mountain.  Thence  it  passes 

*  See,  also,  p.  218. 


3OO  PHYSICAL    GEOGRAPHY. 

a  little  cast  of  south  through  Jaffrey,  and  partly  through  Rinclge ;  it  then 
turns  north-east  to  Kidder  mountain  in  the  south-west  corner  of  Temple, 
from  which  it  extends  south-west  across  the  west  part  of  New  Ipswich  to 
the  Massachusetts  line. 

Altitudes  along  this  principal  water-shed  of  the  state  have  been  already 
given  on  pp.  209-211.  From  the  course  of  this  line  it  will  be  seen  that 
the  drainage  area  of  the  Connecticut  river  in  New  Hampshire  is  of  com 
paratively  uniform  width,  the  water-shed  averaging  about  sixteen  miles 
distant  from  the  river.  The  point  of  least  width  is  in  the  north  part  of 
Orford,  where  it  is  contracted  to  five  miles.  The  farthest  part  drained 
by  this  river  system  from  New  Hampshire  is  in  New  Ipswich,  thirty 
miles  from  the  Connecticut  at  its  nearest  point.  The  length  of  this  basin 
in  New  Hampshire,  in  a  direct  line,  is  185  miles. 

Merrimack  River,  Eastern  Water-shed.  The  line  dividing  the  Merri- 
mack  basin  from  those  of  the  Saco  and  Piscataqua  begins  about  three 
miles  south-west  from  the  White  Mountain  notch,  and  runs  nearly  south 
over  Willey,  Carrigain,  Tripyramid,  Black,  and  Sandwich  mountains, 
passing  through  Elkins's  grant,  the  east  part  of  Waterville,  and  the 
west  part  of  Sandwich,  to  a  point  about  a  mile  and  a  half  north  of  Squam 
lake.  Here  it  turns  to  the  east,  passing  between  Red  Hill  and  Bear 
Camp  ponds,  thence  south-east  to  Ossipce  mountain  in  the  east  part  of 
Moultonborough,  thence  through  the  east  part  of  Tuftonborough  to  a 
point  one  half  mile  south  of  Upper  Beech  pond,  around  which  it  passes, 
running  north-east  to  a  point  about  one  mile  east  of  Water  Village. 

The  place  where  this  water-shed  line  approaches  nearest  to  Lake  Win- 
nipiseogee  is  west  of  Upper  Beech  pond,  one  of  its  bays  being  here  three 
miles  distant.  The  farthest  point  that  is  drained  into  Winnipiseogee  is 
that  last  named,  being  on  the  north  side  of  Batson  pond,  seven  miles 
from  the  lake. 

Thence  it  follows  nearly  the  north-east  and  south-east  boundaries  of 
Wolfeborough  to  Mt.  Delight,  passing  within  one  mile  of  Smith's  pond. 
Thence  it  extends  south  through  the  west  part  of  Brookfield,  over  Crop- 
pie  Crown  mountain,  thence  south-west  through  New  Durham,  nearly 
to  Downing's  mills,  passing  one  mile  south-east  from  Merry-meeting  lake. 
Here  the  course  again  turns  south  to  the  west  corner  of  Farmington, 
then  south-east  three  miles  to  the  Blue  Hills  range,  which  it  follows 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  30! 

across  Strafford.  Thence  it  extends  south  through  Northwood  to  Saddle 
back  mountain,  thence  a  little  south  of  west  through  Deerfield  to  Aliens- 
town  line,  near  Shingle  ponds.  Thence  it  passes  on  a  curve  through  the 
west  and  south  portions  of  Candia  to  Patten's  hill.  From  this  point  it 
follows  nearly  the  west  and  south  boundary  lines  of  Chester,  next  passing 
through  the  north  part  of  Hampstead,  between  Island  pond  and  Phillips 
pond,  Sandown,  thence  north-east  to  near  the  Town  hall  in  Danville, 
thence  east  through  Kingston  village, — the  large  ponds  of  Kingston 
being  tributary  to  Powwow  river  on  the  south.  Thence  its  course  is 
south-east,  passing  through  East  Kingston  village,  and  the  south-west 
corner  of  Kensington,  to  the  Massachusetts  line,  near  the  boundary 
between  South  Hampton  and  Seabrook. 

The  width  of  the  Merrimack  basin  at  its  source,  measured  from  Mt. 
Willey  to  Cannon  or  Profile  mountain,  is  about  fifteen  miles.  This 
increases  to  the  section  from  Brookfield  across  Winnipiseogee  lake  to 
Orange,  which  is  forty-three  miles.  Thence  southward  to  Manchester  it 
remains  very  nearly  the  same.  From  near  Manchester  this  area  widens 
on  the  east,  bending  in  the  direction  of  the  river's  mouth  at  Newbury- 
port.  Its  greatest  width  in  New  Hampshire,  from  the  west  line  of  Sea- 
brook  to  Monadnock  mountain,  is  sixty  miles.  Its  length,  from  Profile 
lake  south  to  the  Massachusetts  line,  is  ninety-eight  miles. 

Androscoggin  River.  The  water-shed  between  the  Androscoggin  and 
Saco  extends  from  the  summit  of  Mt.  Washington  to  Pinkham  notch, 
passing  between  Huntington's  and  Tuckerman's  ravines,  and  thence 
nearly  east,  through  Bean's  purchase  to  the  Maine  line.  Its  course  is 
across  high  mountain  ranges,  which  extend  north  and  south,  and  are 
covered  with  unbroken  forest. 

By  reference  to  our  hydrographic  map,  it  will  be  seen  that  Coos  county, 
north  from  Mt.  Washington,  is  nearly  equally  divided  between  the  Con 
necticut  and  Androscoggin  basins.  The  latter,  as  far  as  included  in  New 
Hampshire,  averages  about  eleven  miles  in  width,  being  sixteen  miles 
wide  at  its  southern  end,  and  fifteen  at  the  sources  of  the  Swift  Diamond 
river,  while  it  is  narrowed  to  almost  nothing  at  Mt.  Carmel.  The  length 
of  this  hydrographic  district,  measured  on  the  eastern  boundary  of  the 
state,  is  seventy-one  miles. 

Saco  River.     The  water-shed  between  the  Saco  and  Piscataqua  starts 


3O2  PHYSICAL    GEOGRAPHY. 

from  the  east  line  of  the  Merrimack  basin  in  Wolfeborough,  and  passes 
east  through  the  north  corner  of  Brookfield  and  near  the  centre  of  Wake- 
field  to  the  Maine  line,  which  it  crosses  between  Balch  and  East  ponds. 

Nearly  the  whole  of  Carroll  county  is  comprised  within  the  Saco  basin, 
which  has  in  New  Hampshire  an  average  width  of  about  eighteen  miles, 
and  a  length,  measured  on  our  eastern  boundary,  of  forty-six  miles. 

Piscataqua  River.  The  south-east  boundary  of  this  district  starts  from 
the  Merrimack  river  water-shed  at  East  Kingston,  and  passes  east  through 
Kensington  village,  thence  north-east  through  the  east  corner  of  Exeter, 
thence  east  and  north-east  through  North  Hampton  to  Breakfast  hill 
between  Greenland  and  Rye,  from  which  it  passes  north-east  through 
Rye  to  Odiorne's  point  at  the  south  side  of  the  mouth  of  the  Piscataqua. 

This  basin  includes  in  New  Hampshire  nearly  all  of  Strafford  and  half 
of  Rockingham  counties,  averaging  about  eighteen  miles  in  width,  and 
forty-five  miles  in  length,  measured  from  Wakefield  to  East  Kingston. 
From  the  sources  of  the  Pawtuccaway  river  to  the  mouth  of  the  Piscat 
aqua  is  thirty  miles,  from  which  point  the  width  of  this  district  diminishes 
northward,  being  ten  miles  at  Farmington. 

Hampton  Falls  River,  &c.  The  portion  of  New  Hampshire  south  of 
the  last  described  water-shed  and  east  from  East  Kingston  and  South 
Hampton,  forming  our  sea-coast  slope,  is  drained  directly  into  the  ocean 
by  Hampton  Falls  and  Taylor's  rivers  and  numerous  smaller  streams,  not 
being  included  in  either  of  the  principal  hydrographic  districts  adjacent. 

The  most  distant  point  of  this  area  from  the  ocean  is  in  the  south-east 
corner  of  Exeter,  six  miles  from  the  coast.  Its  length  from  Odiorne's 
point  to  the  Massachusetts  line  is  thirteen  miles. 

The  accompanying  map  shows  the  dimensions  and  relative  areas  of 
these  hydrographic  basins,  and  the  course  of  water-shed  lines. 

CONNECTICUT  RIVER  SYSTEM. 

The  basin  of  the  Connecticut  comprises  about  3,060  square  miles  in 
New  Hampshire,  or  three  tenths  of  the  area  of  the  state.  The  line  of 
low  water  on  the  west  side  of  this  river  forms  the  boundary  between  this 
state  and  Vermont ;  and  Hall's  stream,  the  third  considerable  tributary 
from  the  right  below  its  source,  continues  this  boundary  between  our 
state  and  the  province  of  Quebec.  In  addition  to  this  area  drained  from 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  303 

New  Hampshire,  the  Connecticut  basin  embraces  about  3,750  square 
miles  in  Vermont,  or  four  tenths  of  that  state,  making  a  total  of  more 
than  6,800  square  miles  in  both  states,  nearly  all  of  which  contributes  to 
the  water-power  of  this  river  along  our  western  border. 

The  general  course  of  the  head  stream  of  the  Connecticut  river, 
passing  through  Second  and  Connecticut  lakes  to  the  mouth  of  Hall's 
stream,  is  S.  60°  W.,*  being  a  distance  of  twenty-five  miles  from  its 
farthest  sources  in  a  direct  line,  and  of  twenty-eight  miles  from  Third 
lake,  following  the  course  of  the  river.  The  descent  along  this  distance 
is  comparatively  rapid,  with  few  and  narrow  intervals.  The  surface  of 
the  country  is  moderately  hilly  but  not  rugged,  and  more  than  nine-tenths 
is  still  covered  with  the  original  forest. 

From  the  mouth  of  Hall's  stream  to  the  head  of  Fifteen-miles  falls  in 
Dalton,  the  general  course  is  S.  13°  W.,  a  distance  of  forty-two  miles  in 
a  direct  line,  or  forty-six  miles,  if  we  follow  the  principal  bends  in  the 
river.  Along  this  whole  distance  are  the  fertile  intervals  of  the  upper 
Connecticut  valley,  varying  from  one  half  mile  to  a  mile  in  width.  The 
surface  back  from  the  immediate  river  valley  rises  in  bold  hills  or  moun 
tains,  and  fully  four  fifths  of  its  area  is  covered  by  forest. 

From  the  head  of  Fifteen-miles  falls,  near  the  mouth  of  John's  river,  to 
the  mouth  of  the  Passumpsic,  the  course  of  the  Connecticut  is  S.  70°  W., 
being  a  distance  of  eighteen  miles  in  a  direct  line,  or  about  twenty, 
following  the  stream.  Opposite  to  this  portion  of  the  river,  on  the  east 
and  south-east,  is  the  elevated  mountain  region  of  the  state.  Here  the 
descent  is  rapid,  and  the  surface  more  broken  than  in  any  other  part  of 
the  course  of  this  river.  Its  direction  is  also  bent  to  the  west  along  this 
distance,  beyond  which  the  general  course  of  the  upper  is  again  followed  in 
the  lower  valley,  with  but  slight  deviation,  almost  to  the  Massachusetts  line. 

This  course  from  the  mouth  of  the  Passumpsic  to  Brattleborough  is 
S.  1 6°  W.,  a  distance  of  103  miles  in  a  straight  line,  or  107  by  the  course 
of  the  river.  Along  this  distance  the  river  intervals  and  terraces  of  the 
valley  usually  extend  from  one  half  to  a  mile  and  a  half  in  width  on 
each  side  of  the  river,  but  are  occasionally  interrupted  on  one  or  both 
sides  by  encroaching  ranges  of  hills.  The  water-shed  which  separates 
this  portion  of  the  Connecticut  basin  from  that  of  the  Merrimack,  every-

where  reaches  a  considerable  elevation,  and  frequently  is  marked  by 
mountains.  The  slope  on  the  west  from  opposite  Haverhill  extends  to 
the  Green  Mountain  range  of  Vermont,  its  greatest  width  being  at  the 
sources  of  White  river,  which  are  thirty-eight  miles  from  the  nearest 
point  of  the  Connecticut,  and  forty-two  miles  from  the  mouth  of  White 
river.  In  the  northern  half  of  Vermont,  a  large  area  east  of  this  moun 
tain  range  is  drained  into  Lake  Champlain  and  the  St.  Lawrence. 

South  from  Brattleborough  the  Connecticut,  for  the  remaining  ten  miles 
in  New  Hampshire,  has  a  general  direction  S.  25°  E.,  again  resuming  nearly 
its  former  course  after  crossing  the  Massachusetts  line.  Of  this  basin,  from 
the  mouth  of  the  Passumpsic,  probably  two  thirds  are  covered  with  forest. 

The  entire  length  of  the  Connecticut  from  Third  lake,  following  its 
principal  bends  along  our  western  border  to  the  Massachusetts  line,  is 
21 1  miles. 

Altitudes  at  various  points,  with  distances  from  Third  lake,  are  given 
in  the  following

The  principal  tributaries  which  the  Connecticut  receives  from  Vermont 
are  Nulhegan  river  at  Brunswick,  Passumpsic  river  at  Earner,  Wells 
river  at  Newbury,  Wait's  river  at  Bradford,  Pompanoosuc  at  Norwich, 
White  river  at  White  River  Junction,  Quechee  river  at  Hartland,  Black 
river  at  Springfield,  Williams  river  at  Rockingham,  and  West  river  at  Brat- 
tleborough.  A  portion  of  this  basin  in  Vermont  is  drained  by  the  Deer- 
field  river,  passing  into  Massachusetts,  while  in  New  Hampshire  the  head 
waters  of  Miller's  river  include  portions  of  Richmond,  Fitzwilliam,  and 
Rindge.

3O6  PHYSICAL  GEOGRAPHY. 

MERRIMACK  RIVER  SYSTEM. 

The  Merrimack  river  receives  this  name  south  from  Franklin,  where 
the  Pemigewasset  and  Winnipiseogee  rivers  unite.  Its  area  of  drainage 
in  New  Hampshire  is  about  3,825  square  miles,  or  four  tenths  of  the 
state.  This  river  system  comprises  the  central  portion  of  New  Hamp 
shire,  including  our  principal  lake  region,  and  has  its  source  in  the  centre 
of  the  White  Mountains.  Our  largest  cities  have  grown  up  along  the 
Merrimack,  and  its  name  has  become  associated,  like  those  of  Winnipiseo 
gee  lake  and  Mt.  Washington,  with  all  descriptions  of  the  Granite  State. 

From  its  source  in  Franconia  to  the  Massachusetts  line,  its  general  direc 
tion  is  S.  8°  E.,  being  100  miles  in  a  direct  course,  or  105  miles  following 
the  principal  bends  in  the  river.  The  first  thirty-eight  miles  of  this  dis 
tance  is  nearly  S.  5°  E. ;  it  then  bends  nearly  west  four  miles  to  Bristol 
village,  and  this  is  the  only  considerable  deviation  from  its  general  course. 
From  this  point  to  the  mouth  of  the  Suncook  river,  a  distance  of  thirty- 
three  miles,  it  runs  nearly  S.  20°  E.,  thence  a  distance  of  thirty  miles  its 
course  is  about  S.  2°  E.  to  the  Massachusetts  line.  After  passing  beyond 
the  limits  of  the  state,  the  Merrimack  bends  to  the  north-east,  the 
boundary  line  south  of  Rockingham  county  being  parallel  with  its  course 
and  three  miles  distant.  Its  total  length  is  about  144  miles. 

The  upper  part  of  the  Pemigewasset  valley  is  narrow,  and  closely 
bordered  on  both  sides  by  mountain  ranges.  The  intervals  begin  in 
Thornton  and  Campton.  The  high  sandy  plains,  which  are  characteristic 
of  this  valley  southward,  commence  at  New  Hampton.  The  alluvial 
area  along  this  river  is  much  wider  than  on  the  Connecticut,  and  the 
hills  rise  less  abruptly  upon  either  side.  The  proportion  of  this  basin 
covered  by  forest  is  probably  nine  tenths  north  of  Plymouth,  and  two 
thirds  southward. 

Winnipiseogee  Lake.  The  hydrographic  basin  of  Winnipiseogee  lake 
comprises  about  350  square  miles.  Its  waters  flow  into  the  Merrimack, 
though  the  general  level  of  the  country  would  seem  to  ally  it  with  the 
waters  of  the  Saco  or  Cochecho  valley.  The  height  of  the  divide 
separating  it  from  the  latter  is  only  seventy-two  feet  at  the  lowest  place. 

The  lake  is  quite  irregular  in  form.  Its  general  course  is  S.  25°  E., 
with  several  long  bays  or  arms.  On  the  south  is  Alton  bay,  eight  or  ten 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  3O/ 

miles  long,  which  resembles  a  fiord  more  than  any  of  the  other  arms. 
On  the  south-east  is  Wolfeborough  bay,  in  close  connection  with  Smith's 
pond.  On  the  north-east  are  two  branches  into  Moultonborough.  On 
the  north-west  is  the  expanse  known  as  Meredith  bay.  The  western 
shore  is  comparatively  straight  from  Meredith  Village  to  Alton  Bay  vil 
lage.  The  hills  about  the  lake  are  steeper  than  the  average  in  other 
parts  of  the  state. 

The  length  of  the  lake  proper  is  19  miles.  The  breadth  at  the 
widest  part  is  8i  miles.  Its  area  is  69.8  square  miles.  If  Long  bay, 
which  is  properly  an  expansion  of  the  outlet,  be  added,  the  area  becomes 
71.8  square  miles. 

The  lake  abounds  in  islands.  Their  number,  large  and  small  together, 
is  two  hundred  and  seventy-four.  The  water  is  remarkably  pure,  but 
shallow.  No  soundings  have  been  made,  but  no  part  is  likely  to  be  over 
two  hundred  feet  deep.  By  the  dam  at  the  outlet  of  this  lake  a  depth  of 
six  feet  is  made  available  for  the  use  of  manufacturing  companies  in  the 
dry  season.  The  top  of  this  dam  is  502  feet  above  mean  tide.

From  the  north-west  side  it  receives  Blackwater  and  Warner  rivers  in 
Hopkinton,  North  Branch,  near  the  north  line  of  Antrim,  and  Nubanusit 
river  at  Peterborough.

Hampshire  is  about  775  square  miles,  or  one  twelfth  of  the  state.  About 
900  square  miles  from  Maine  are  also  drained  by  this  river  through 
New  Hampshire. 

The  course  of  the  Androscoggin  from  Umbagog  lake  is  first  a  little 
south  of  west  about  five  miles  to  the  mouth  of  Clear  stream,  from  which 
its  general  course  is  S.  5°  W.  to  the  mouth  of  Moose  river  at  Gorham, 
a  distance  of  thirty-three  miles,  following  the  bends  of  the  river.  Along 
this  portion  of  its  course  the  Androscoggin  flows  almost  directly  towards 
the  highest  and  most  massive  range  of  the  White  Mountains,  approach 
ing  within  ten  miles  of  the  summit  of  Mt.  Washington.  At  Gorham, 
this  barrier  turns  the  river  sharply  to  the  east,  a  distance  of  nine  miles, 
carrying  it  into  the  state  of  Maine. 

The  length  of  the  Magalloway,  from  its  source  in  Pittsburg,  near  the 
most  northern  point  of  New  Hampshire,  to  its  mouth,  is  thirty-three  miles 
in  a  direct  line,  or  thirty-nine  miles,  following  the  principal  bends  in  the 
stream.  A  large  portion  of  this  river  is  nearly  level  and  very  meander 
ing,  although  its  general  course  is  nearly  straight.  The  total  length  of 
river  from  Magalloway  lake,  the  source  of  this  stream,  to  the  point  where 
the  Androscoggin  enters  Maine,  is  eighty-six  miles. 

The  most  distant  point  in  Maine  drained  by  the  range  of  lakes  is  about 
forty  miles  in  a  direct  line  from  the  junction  of  these  waters  with  the 
Magalloway.  We  copy,  from  Wells's  Water  Power  of  Maine,  the  follow

Our  eastern  boundary  runs  across  Umbagog  lake,  dividing  it  in  nearly 
equal  portions  to  the  two  states.  The  length  of  this  lake  is  about  eleven 
miles,  the  north  portion  being  bent  east  into  Maine.  By  the  dam  in 
Errol,  four  miles  below  its  mouth,  the  outlet  is  made  navigable  for  a

Almost  the  entire  area  drained  by  the  range  of  lakes  and  the  Magallo 
way  is  unbroken  forest,  which  also  covers  nine  tenths  of  this  basin  south 
ward  in  New  Hampshire.

SACO  RIVER  SYSTEM. 

The  area  drained  by  this  system  in  New  Hampshire  is  about  850 
square  miles,  or  one  eleventh  of  the  state. 

The  distance  in  a  straight  line  from  the  head  of  the  Saco  beyond  the 
White  Mountain  notch  to  its  point  of  crossing  the  Maine  line  is  about 
twenty-five  miles,  the  direction  being  nearly  south-east.  Following  the 
course  of  the  river,  this  distance  is  about  thirty-four  miles.  The  first 
eleven  miles  it  runs  a  little  east  of  south,  with  high  mountains  bending 
in  steep  and  gracefully  curved  slopes  to  form  its  valley.  The  next  nine 
miles  extend  nearly  east,  through  the  level  intervals  of  Bartlett  to  the

mouths  of  Ellis  river  and  East  Branch.  The  river  then  turns  nearly 
south  eight  miles  to  the  mouth  of  Swift  river  in  Conway,  from  which 
point  it  flows  east  six  miles  to  Maine  line. 

The  southern  portion  of  this  basin  in  New  Hampshire  is  drained  by  the 
Ossipee  river,  which  passes  into  Maine.  A  large  part  of  this  area  about 
Ossipee  lake  is  comparatively  level,  consisting  of  sandy  plains.  The 
proportion  of  forest  in  the  whole  basin  is  probably  about  three  fourths.

RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  313 

PISCATAQUA  RIVER  SYSTEM. 

The  Piscataqua  river  is  formed  by  the  union  of  the  Cochecho  and 
Salmon  Falls  rivers  at  Dover.  The  second,  in  its  whole  length,  with  the 
Piscataqua,  constitutes  a  part  of  our  eastern  state  boundary.  The  area 
of  this  basin  in  New  Hampshire, — those  towns  on  the  coast  which  drain 
directly  into  the  ocean  being  also  included  in  this  measurement, — is  about 
825  square  miles,  or  nearly  one  eleventh  of  the  state. 

From  East  pond,  the  source  of  Salmon  Falls  river,  to  the  mouth  of 
the  Piscataqua,  is  nearly  thirty-eight  miles  in  a  straight  line,  the  course 
being  S.  20°  E.  By  the  course  of  the  river  this  distance  is  thirty-nine 
miles,  the  length  of  Salmon  Falls  river  being  twenty-eight  miles,  and  of 
the  Piscataqua,  from  the  junction  of  this  river  with  the  Cochecho,  eleven 
miles.  The  course  of  Salmon  Falls  river  in  the  first  twelve  miles  is 
nearly  south.  The  next  thirteen  miles  to  Salmon  Falls  is  nearly  south 
east  ;  thence  the  course  is  south  seven  miles  to  the  mouth  of  Great  bay, 
thence  south-east  about  seven  miles  to  the  ocean,  three  miles  below 
Portsmouth. 

This  river  is  affected  by  tide  to  Dover  and  South  Berwick.  Between 
the  township  of  Durham  and  those  of  Greenland  and  Newington  is  a 
wide  tidal  basin,  which  receives  the  waters  of  several  rivers.  Upon 
Exeter  or  Squamscot  river,  the  largest  of  these,  tide  extends  to  the 
village  of  Exeter.  The  area  of  this  estuary,  south-west  from  Dover 
point,  including  Little  and  Great  bays,  is  about  nine  square  miles.  From 
Dover  point  to  Portsmouth  the  Piscataqua  is  about  half  a  mile  wide. 
Below  this  city  it  contains  numerous  islands,  the  largest  of  which  consti 
tutes  the  township  of  Newcastle. 

The  section  of  New  Hampshire  drained  by  this  river  system  is,  for 
the  most  part,  level.  Probably  about  one  third  is  covered  with  forest.

EFFECT  OF  GEOGRAPHIC  AND  CONTINENTAL  POSITION. 

If  we  inquire  into  the  causes  which  influence  the  hydrographic  char 
acter  of  New  Hampshire,  we  find  that  the  situation  of  our  state  gives 
us  favorable  conditions  of  climate,  producing  well-watered  fields  for  the 
farmer,  and  abundant  water-power  for  manufacturing  industry. 

New  Hampshire  is  situated  between  42°  40'  and  45°  18'  23"  north 
latitude,  and  between  70°  37'  and  72°  37'  longitude  west  from  Green- 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  315 

wich.  In  consequence  of  this  geographic  position,  almost  equidistant 
between  the  equator  and  the  pole,  the  amount  of  evaporation  in  New 
Hampshire  is  only  that  due  to  a  moderate  temperature;  the  moisture  of 
the  soil  is  not  burned  away  by  long  continued  and  excessive  heat,  nor 
are  the  sources  of  water  supply  wholly  cut  off  by  long  and  uninterrupted 
cold.  For  the  same  reason  the  winds  are  variable,  not  constant  as 
within  the  tropics,  but  coming  throughout  the  year  from  every  quarter  of 
the  compass,  rarely  for  more  than  two  or  three  days  from  the  same  point, 
bringing  heat  and  cold,  moisture  and  dryness,  in  succession.  It  follows 
also  from  this  geographic  position,  that  the  precipitation  of  moisture  is 
non-periodic.  It  occurs  in  the  form  of  either  rain  or  snow  at  all  seasons, 
tending  to  make  the  volume  of  streams  constant  throughout  the  year. 
Its  fall  is  usually  gentle,  often  occupying  several  days  for  the  deposition 
of  a  single  inch  of  water.  On  this  account  sudden  and  great  inunda 
tions  are  of  rare  occurrence.  It  is  generally  attended,  also,  with  a  pro 
tracted  continuance  of  cloud,  fog,  or  mist,  which  lessens  evaporation, 
and,  in  consequence,  increases  the  volume  to  be  removed  by  drainage. 

The  continental  position  of  New  Hampshire  has  the  further  effect  to 
produce  a  larger  rainfall  and  a  smaller  amount  of  evaporation  than  the 
average  for  this  latitude.  It  is  situated  on  the  coast,  and  is  constantly 
visited,  therefore,  by  currents  of  air  directly  from  the  ocean,  tending  to 
produce  a  more  equable  temperature,  increased  rainfall,  and  a  humid 
atmosphere.  It  lies  directly  in  the  current  of  the  south-west  winds  from 
the  Gulf  of  Mexico.  This  great  inland  sea  is  noted  for  its  remarkably 
high  temperature,  to  which  it  presents  an  evaporating  surface  of  800,000 
square  miles  in  area.  The  prevailing  course  of  our  storms  being  from 
the  west  and  south-west,  it  is  to  a  very  large  extent  from  this  source  that 
their  vapor  is  derived.  This  is  precipitated  upon  us  in  our  so-called 
north-easterly  storms,  the  moisture  being  brought  in  large  measure  by  an 
upper  current  whose  course  is  opposite  to  that  experienced  below. 

This  deposition,  also,  is  relatively  more  abundant  here  than  farther 
south,  because  of  the  colder  currents  of  air  which  these  storms  encoun 
ter  here,  after  uniting  with  which  their  combined  capacity  for  retaining 
moisture  becomes  greatly  diminished,  the  excess  necessarily  falling  in  the 
form  of  rain.  The  whole  circulation  of  the  Arctic  ocean,  including  all 
the  waters  which  are  brought  in  by  the  currents  through  Behring's  strait,

and  from  the  north  coast  of  Europe,  after  being  reduced  to  a  very  low 
temperature  and  loaded  with  vast  masses  of  ice,  is  poured  in  a  constant 
stream  by  the  east  coast  of  Greenland,  by  Baffin's  bay,  and  the  straits 
north  of  Hudson's  bay  directly  upon  the  shores  of  Labrador  and  New 
foundland,  and  is  afterwards  carried  as  a  cold  inshore  drift  along  our 
coast.  Our  north-east  and  east  winds  are,  in  consequence,  of  low  tem 
perature,  producing  an  excessive  rainfall  by  their  meeting  with  the 
warmer  south-west  currents  of  our  prevailing  storms.  By  another 
remarkable  oceanic  current,  known  as  the  Gulf  stream,  enormous  vol 
umes  of  water,  of  almost  tropical  temperature,  are  brought  into  sudden 
contact  with  this  polar  current  off  the  coast  of  Newfoundland.  The 
warm  atmosphere  overhanging  the  Gulf  stream  is  saturated  with  mois 
ture,  and  on  meeting  the  cold  atmosphere  of  the  polar  current  this  is 
condensed,  covering  the  Grand  Banks,  the  Gulf  of  St.  Lawrence,  and 
the  adjacent  ocean  and  land  with  thick  and  comparatively  constant  fogs. 
These  vapors  are  brought  over  our  state  by  east  and  north-east  winds, 
sometimes  remaining  for  days,  or,  with  some  intervals,  for  weeks  together, 
especially  in  the  latter  part  of  summer.  The  cool  fogs  of  the  dog  days 
throughout  New  England,  which  are  in  marked  contrast  with  the  sultry 
heat  of  that  season  in  the  interior,  are  derived  from  this  source,  or  in 
part  from  a  similar  condensation  of  the  moisture  of  southerly  winds 
blowing  from  the  Gulf  stream  across  the  cold  ocean  current  along  our 
shores.  The  obvious  effect  of  these  fogs,  occurring  most  notably  in  the 
midst  of  the  protracted  heat  of  summer,  when  streams  tend  to  run 
lowest,  is  greatly  to  diminish  the  evaporating  power  of  the  sun  and 
reserve  a  large  proportion  of  the  rainfall  for  removal  by  drainage. 

The  conditions  of  our  climate,  resulting  from  geographic  and  conti 
nental  position,  are  thus  such  as  to  give  increased  volume  and  unusual 
constancy  to  our  streams. 

PHYSICAL  CHARACTER  OF  NEW  HAMPSHIRE  AS  RELATED  TO  WATER- 
POWER. 

The  consideration  of  the  hydrographic  features  of  the  state  is  of  espe 
cial  interest,  as  exhibiting  the  extent  and  value  of  its  water-power.  Our 
river  systems  are  hardly  more  important  as  a  part  of  the  physical  geog 
raphy  than  they  have  already  become  in  their  relation  to  the  industries 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  317 

and  wealth  of  the  state.     A  general  view  of  the  nature  of  these  resources 
will  cause  us  to  see  utility  as  well  as  beauty  in  our  river  and  lake  scenery. 

Among  the  physical  characteristics  of  the  state  which  affect  the  amount 
and  availability  of  its  water-power,  we  should  first  consider  its  geological 
structure.  Here  the  most  noticeable  feature  in  this  relation  is  the  ability 
of  the  ledges  to  resist  decomposition.  This  is  the  prevailing  character  of 
very  ancient  rock  formations.  They  resist  the  wearing  action  of  water, 
breaking  the  course  of  streams  with  numerous  falls  and  abrupt  rapids, 
and  maintaining  the  uneven  condition  of  river  beds,  which  renders  water- 
power  capable  of  use.  The  importance  of  this  feature  will  be  rightly 
estimated  by  a  comparison  with  the  prevailing  form  of  river  channel  in 
the  south-western  portion  of  the  United  States,  where  the  rivers  find 
their  way  by  an  almost  subterranean  passage  through  canons  many  miles 
in  length  and  hundreds  of  feet  deep,  while  the  parched  and  sterile  country 
is  rendered  impassable  by  their  yawning  chasms.  This  character  of  our 
rocks  also  reduces  the  amount  of  water,  which  is  absorbed  through  crev 
ices  and  fissures  in  strata,  and  which,  in  a  season  of  drouth,  is  lifted  to 
the  surface,  and  burned  away  by  evaporation.  It  is  also  of  peculiar 
importance  in  relation  to  the  water-retaining  capacity  of  our  lakes  and 
ponds,  these  being  in  the  majority  of  cases  underlaid  and  walled  in  with 
impervious  rock.  The  same  consideration  insures  the  reliability  of 
artificial  reservoirs  wherever  natural  slopes  of  land  admit  of  their  con 
struction. 

It  is  also  to  be  noticed  that  the  disintegrated  material,  which  almost 
everywhere  overlies  the  solid  rock,  is  comparatively  shallow.  The  sides 
and  bed  of  nearly  all  our  streams,  at  points  where  falls  or  rapids  exist, 
are  rock-set  and  rock-bound,  though  apparently  covered  with  earth. 
Ravages  of  river  beds  and  diversions  of  river  courses,  which  in  alluvial 
districts  are  productive  of  much  inconvenience,  or  even  of  serious  losses, 
are  on  this  account  very  rare.  Canals  and  race-ways  can  be  constructed 
in  permanent  material,  and  when  once  completed  need  no  repairs.  Mills 
and  accompanying  structures  can  be  planted  on  ledge  bottom,  and  thus 
defy  the  treacherous  undermining  of  deep  currents.  A  permanent  dam 
can  be  built  at  almost  any  point  where  the  slope  of  a  stream  is  sufficient 
to  produce  a  rapid ;  so  that,  dam  succeeding  dam,  the  whole  descent  of 
the  stream  may  be  utilized,  the  damage  from  flowage  or  from  wear  upon

the  banks  being  as  a  general  statement  very  small.  To  this  comparative 
shallowness  of  earth,  ancTconsequent  prominence  of  the  underlying  rock, 
we  also  owe  the  large  amount  of  water-power  which  occurs  on  our  rivers 
in  the  lower  portion  of  their  course.  Were  the  geological  character  of 
our  sea-coast  the  same  as  that  of  the  Southern  states,  our  rivers  near  the 
sea  would  be  worthless  for  water-power,  having  deepened  their  valleys 
through  the  loose  strata  so  as  to  be  affected  far  inland  by  the  rise  of  the 
tide,  while  their  size  is  such  that  they  would  be  of  little  value  for  pur 
poses  of  navigation  in  comparison  with  the  power  which  they  now  furnish 
for  our  manufactures. 

The  character  of  the  surface  of  New  Hampshire  should  also  be  con 
sidered  in  its  effect  upon  the  water-power.  Under  this  head  the  most 
important  inquiry  is  in  regard  to  the  contour  or  general  elevation  of  tJie 
state  in  different  sections,  including  the  arrangement  and  character  of  its 
slopes,  and  the  distinguishing  features  of  its  mountains,  drainage  basins, 
and  river  valleys. 

From  the  tables  of  altitudes  already  given  in  this  chapter,  it  is  seen 
that  Connecticut  lake,  the  principal  source  of  our  largest  river,  exceeds 
1600  feet  above  the  level  of  the  sea.  The  descent  of  this  river  from  this 
point  to  the  north  line  of  Massachusetts  is  more  than  1400  feet.  This 
total  descent  is  distributed  over  the  entire  distance  of  its  course,  furnish 
ing  a  succession  of  valuable  water-powers  often  equal  to  those  which 
have  caused  the  rapid  building  up  of  such  cities  as  Manchester,  Lowell, 
and  Lawrence.  Although  no  considerable  distance  along  this  river  is 
destitute  of  sufficient  descent  to  produce  upon  improvement  a  valuable 
water-power,  it  is  not  intended  to  convey  the  idea  that  the  rate  of  fall  is 
nearly  uniform  along  its  entire  course.  By  recurrence  to  the  list  of  alti 
tudes,  it  will  be  seen  that  its  descent  in  the  first  17  miles,  to  the  bridge 
between  West  Stewartstown  and  Canaan,  Vt,  is  about  600  feet ;  in  the 
next  44  miles,  to  the  mouth  of  John's  river  in  Dalton,  the  descent  is  about 
200  feet ;  in  the  next  24  miles  its  descent  is  again  rapid,  amounting  to 
about  400  feet,  the  course  of  the  river  being  transferred,  with  a  westerly 
offset  by  the  rapids  of  Fifteen-miles  falls,  from  the  Upper  to  the  Lower 
Connecticut  valley.  From  the  northern  continuation  of  the  latter  valley 
it  receives  the  waters  of  the  Passumpsic.  In  the  remaining  1 1 3  miles  of 
its  course  along  our  western  border,  its  descent  is  about  230  feet,  which 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  319 

is  divided  into  successive  falls  and  rapids,  separated  by  only  a  few  miles 
from  each  other,  along  this  entire  distance.  This  river  leaves  the  state 
at  a  height  of  200  feet  above  sea. 

The  water-power  of  this  river  at  one  of  its  principal  falls,  about  two 
miles  north  of  White  River  Junction,  is  illustrated  by  the  annexed  plate, 
prepared  by  Mr.  J.  T.  Woodbury,  of  the  Thayer  Department  of  Civil 
Engineering,  Dartmouth  college.  He  states  that  the  amount  of  flow  of 
the  Connecticut  at  Ledyard  bridge  on  May  4,  1874,  was  3,498,636  gallons 
per  minute,  and  estimates  that  in  the  driest  season  the  flow  might  be 
reduced  to  one  eighth  of  this  amount.  A  dam  10.8  feet  above  present 
surface  at  the  head  of  the  falls,  one  fourth  mile  above  the  paper  mill, 
flows  back  to  this  bridge,  and  gives  a  fall  of  31^  feet  at  a  distance  of  half 
a  mile.  A  canal  now  exists  on  the  New  Hampshire  side,  formerly  used 
for  the  river  navigation,  in  which  a  depth  of  ten  feet  is  secured  by  this 
dam.  This  canal  passes  through  450  feet  of  hornblende  schist,  and 
would  require  enlargement.  On  the  Vermont  side  a  canal  can  be  con 
structed  of  any  desired  length,  passing  through  the  common  terrace 
formation  of  the  river. 

East  and  south-east  from  the  point  where  the  Connecticut  river  enters 
its  lower  valley  is  the  extended  mountain  region  of  New  Hampshire. 
From  the  wide  interval  on  the  Lower  Ammonoosuc  river,  seven  miles 
south-west  from  Mt.  Washington,  to  the  place  where  that  river  empties 
into  the  Connecticut,  is  a  descent  of  about  1 1 50  feet  The  lowest  point 
of  the  water-shed,  dividing  the  waters  of  the  Lower  Ammonoosuc  from 
those  of  the  Saco,  has  an  elevation  of  over  1900  feet  above  the  sea. 
Here  is  an  area  of  1300  square  miles,  or  one  seventh  of  the  area  of  the 
whole  state,  thickly  set  with  mountains  which  vary  in  height  from  3000 
to  6000  feet  above  the  level  of  the  sea,  the  bottoms  of  its  valleys  varying 
from  1000  to  2000  feet  in  altitude.  These  mountains  constitute  a  group 
in  the  general  form  of  an  oblique  parallelogram,  having  its  corners  in 
Bethlehem,  Shelburne,  Conway,  and  Warren.  Of  course  any  such  rigid 
boundaries  must  be  imperfect;  the  south  line  should  be  bent  farther 
south  at  the  middle  to  include  the  high  mountains  of  Sandwich;  the 
mountains  of  Orford,  and  those  on  the  opposite  side  of  the  river  in  Ver 
mont,  seem  to  be  the  south-western  extension  of  this  central  group, 
while  in  a  north-eastern  direction  it  is  continued  into  the  state  of  Maine. 


32O  PHYSICAL    GEOGRAPHY. 

The  most  elevated  portion  of  that  state,  extending  north-easterly  across 
it  a  little  north  of  its  centre,  covered  with  numerous  lakes  and  isolated 
mountains,  is  the  virtual  extension  of  the  more  elevated  area  of  our 
White  Mountain  region.  This  area  is  not,  however,  continuous  to  Con 
necticut  lake,  from  which  it  is  separated  by  the  drainage  basin  of  the 
Upper  Ammonoosuc  and  the  deep  valley  of  the  Androscoggin.  The 
general  direction  of  mountain  chains  of  the  Appalachian  system  is  thus 
seen,  although  the  arrangement  of  our  mountains  departs  from  the 
general  type  of  the  great  Alleghanian  ranges,  as  seen  in  Vermont  and 
Massachusetts,  Pennsylvania,  Virginia,  and  North  Carolina.  Instead  of 
occurring  as  one  continuous  chain,  our  mountains  form  a  group,  made  up 
of  several  parallel  ridges  or  short  chains,  extending  north  and  south,  the 
highest  summits  of  these  successive  ridges,  in  order  from  south-west  to 
north-east,  being  Moosilauke,  Kinsman,  Lafayette,  Twin  mountain,  Mt. 
Washington,  and  Mt.  Carter.  East  and  west  ridges  and  scattered  peaks 
also  occur,  especially  near  the  south  and  south-east  limits  of  the  group. 

The  relation  which  this  great  mountain  region  holds  to  the  water- 
power  of  the  state  is  three-fold.  It  places  one  seventh  of  our  state  at  a 
greater  elevation  above  the  sea  than  any  other  section  of  New  England, 
giving  a  correspondingly  increased  amount  of  water-power  in  the  descent 
of  its  streams.  From  this  elevated  mountain  area  a  gradual  slope 
extends,  varied  by  transverse  ranges  of  hills  and  outcropping  ledges  in 
the  channels  of  rivers,  producing  falls  or  rapids  to  within  a  few  miles  of 
the  ocean.  This  increased  amount  and  convenient  distribution  of  water- 
power  cannot  be  too  highly  estimated.  The  available  power  of  the 
Merrimack  river  alone  has  been  stated  by  good  authority  to  be  double 
that  of  all  France. 

The  influence  of  mountains  in  producing  an  increased  rainfall  is  well 
known.  Observations  in  the  mountain  districts  of  northern  England 
show  a  rainfall  frequently  three  or  four  times  that  of  the  lowland  around. 
The  average  rainfall  at  Edinburgh,  200  feet  above  the  sea,  in  three  suc 
cessive  years,  was  30  inches ;  in  the  Pentland  hills,  a  few  miles  south,  at 
700  feet  above  sea,  it  was  37.4  inches ;  at  900  feet  above  sea,  49.2  inches. 
Sufficient  observations  have  never  been  taken  to  determine  the  rainfall 
of  our  mountain  region,  and  special  circumstances  may  very  much 
reduce  this  proportion  of  increase,  but  it  cannot  be  doubted  that  a  much 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  321 

larger  amount  of  rain  and  snow  is  collected  here  than  upon  the  same 
area  in  any  other  part  of  New  Hampshire.*  This  is  effected  by  the 
refrigeration  of  currents  of  air,  coming  in  contact  with  the  relatively  cool 
mountain  ridges,  their  moisture  being  thereby  condensed  and  precipitated 
as  rain.  The  clustered  arrangement  of  our  mountains  and  their  disposi 
tion  in  numerous  short  ranges,  transverse  to  the  direction  of  our  pre 
vailing  storms,  would  tend  to  increase  their  influence  in  this  respect. 

The  third  consideration  to  be  noticed  is,  that  this  whole  area  is  heavily 
wooded,  with  the  small  exception  of  such  alpine  summits  as  have  an 
elevation  more  than  4000  feet  above  the  sea.  This  condition  prevents 
the  very  rapid  drainage  which  would  otherwise  produce  overwhelming 
freshets,  sweeping  all  before  them,  after  which  the  streams  would  dwindle 
to  mere  rills,  worthless  for  water-power.  By  this  clothing  of  forest, 
however,  the  large  rainfall  of  this  area  is  stored  up,  as  in  a  sponge,  and 
gradually  given  forth,  producing  in  our  mountain-fed  streams  one  of  the 
principal  resources  of  our  water-power  when  most  needed  in  the  drouth 
of  summer.  This  effect  of  forests  is  due  to  several  causes.  A  great 
amount  of  decaying  vegetable  materials  and  mosses,  which  become 
saturated  with  rain,  everywhere  covers  the  ground  in  our  forests,  and  the 
earth  is  loosened  through  which  tree  roots  have  forced  their  passage, 
giving  water  a  chance  to  penetrate  it, — from  both  which  conditions  its 
volume,  when  in  surplus,  is  husbanded  against  too  sudden  removal.  Thus 
the  forest  acts  as  a  capacious  reservoir  for  retaining  the  water  as  it  falls. 
A  further  office  is  the  protection  of  the  ground  from  the  parching  heat 
of  the  sun,  and  from  the  similar  effect  of  drying  winds,  producing  a 
permanence  and  constancy  in  the  springs  on  which  the  summer  volume 
of  our  streams  mainly  depends.  Forests  also  check  the  waste  of  winter 
snow  as  well  as  of  summer  rain.  Patches  of  ice  and  snow  may  be  found, 
as  late  as  early  June,  lying  here  and  there  in  the  defiles  and  ravines  of 
our  northern  woods,  and  even  late  in  summer  in  secluded  mountain 
glens,  saturating  the  ground  as  they  melt,  and  sending  off  streamlets  to 
the  nearest  brook  or  river.  It  will  be  seen  that  our  forests  are,  to  an 
important  extent,  so  situated  as  to  exercise  their  characteristic  influence 


*The  rainfall  at  the  summit  of  Mt.  Washington  during  the  first  year  of  observation  was  55  inches,  against  an 
average  annual  rainfall  varying  from  35  to  46  inches  in  other  portions  of  the  state  (p.  135).

upon  the  constancy  of  water-power  to  the  best  advantage,  namely,  upon 
the  mountain  region  of  the  state.  Thus  located,  it  is  certain  that  they 
will  remain  for  a  long  time  substantially  as  they  now  are,  deprived  indeed 
of  their  heavier  timber,  but  still  dense  woods ;  so  that  this  effect,  which 
is  unquestionably  of  great  importance  in  a  consideration  of  our  water- 
power,  will  be  at  the  same  time  permanent.  (See  p.  123.) 

The  source  of  the  main  stream  of  the  Merrimack  river, — better  known 
north  from  its  confluence  with  the  Winnipiseogee  under  the  name  Pemi- 
gewasset, — is  Profile  lake,  situated  in  the  midst  of  the  Franconia  ranges, 
at  the  very  foot  of  the  mountain  wall  from  whose  top  hang  the  jutting 
rocks  that  make  up  the  profile  of  the  Old  Man  of  the  Mountains.  This 
little  mountain  lake  is  about  1950  feet  above  the  sea.  The  first  consider 
able  tributary  which  the  Pemigewasset  receives  is  the  East  Branch,  which 
drains  a  wholly  uninhabited  basin  150  square  miles  in  area,  bounded,  and 
in  the  middle  almost  crossed,  by  ranges  of  high  mountains.  The  descent 
of  this  river,  to  the  mouth  of  the  East  Branch,  in  a  distance  of  nine  miles, 
is  about  600  feet.  From  this  point  to  Plymouth,  a  distance  of  1 8  miles,  it 
descends  about  900  feet ;  in  the  next  25  miles  to  Franklin,  where  it  receives 
the  Winnipiseogee,  it  descends  about  175  feet,  the  descent  from  Lake 
Winnipiseogee,  500  feet  above  the  sea,  being  225  feet.  From  this  place 
to  the  southern  boundary  of  the  state,  a  distance  of  53  miles,  its  descent 
is  about  185  feet,  the  height  of  the  Merrimack  at  the  average  stage  of 
water  at  this  point  being  90  feet  above  the  sea.  The  water-power  of  this 
distance  is  located,  as  on  the  Connecticut,  at  numerous  falls,  separated 
from  each  other  by  intervals  of  a  few  miles  each,  affording  unimproved 
sites  for  manufacturing  cities  as  favorable  as  any  already  occupied.  The 
tributaries  of  this  river  are  also  specially  important  for  their  water-power. 

North-east  of  the  White  Mountains  a  large  amount  of  water-power  is 
furnished  by  the  Androscoggin  river,  which  has  its  sources  and  the  lower 
portion  of  its  course  in  the  state  of  Maine.  Being  connected  with  a 
chain  of  lakes  which  can  be  employed  as  immense  reservoirs, — for  which 
they  are  already  used  to  obtain  a  sufficient  supply  of  water  at  the  last 
part  of  the  log-driving  season, — this  river  can  be  made  perfectly  reliable 
for  water-power  in  the  driest  summer.  The  sources  of  this  river,  in  both 
its  upper  drainage  areas  of  the  range  of  lakes  and  Magalloway  river,  are 
from  the  high  water-shed  ridge  which  forms  the  north-west  boundary  of 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  323 

Maine,  having  an  altitude  of  nearly  3000  feet  above  the  sea.  The  upper 
portion  of  the  range  of  lakes  is  1500  feet  in  altitude;  Umbagog  lake, 
about  1250  feet.  At  the  east  line  of  New  Hampshire  the  Androscoggin 
is  about  700  feet  above  the  sea.  The  great  value  of  this  very  reliable 
water-power,  for  the  manufacture  of  lumber, — of  which  there  is  an  almost 
inexhaustible  supply  on  the  lakes  and  streams  above, — cannot  fail  to  be 
appreciated  and  more  fully  employed. 

Although  the  south-eastern  portion  of  the  state  along  the  coast  is 
comparatively  level  and  of  small  altitude,  the  descent  of  its  rivers  is 
gradual,  in  consequence  of  the  projecting  strata  of  solid  rock,  being 
broken  by  falls  to  within  a  short  distance  of  the  sea,  and  affording  very 
valuable  facilities  for  manufacturing.  The  water-shed  between  the  lower 
part  of  the  Merrimack  in  New  Hampshire,  and  the  section  drained  north 
easterly  toward  the  Piscataqua,  is  very  low.  By  reference  to  our  tables 
of  altitudes,  it  will  be  seen  that  the  highest  point  on  the  Nashua  &  Roch 
ester  Railroad  is  only  345  feet  above  the  sea.  Phillips  pond,  the  head  of 
Exeter  river,  has  an  altitude  of  2 1 5  feet.  The  sources  of  Cochecho  and 
Salmon  Falls  rivers  are  among  the  hills  at  the  south-east  end  of  Lake 
Winnipiseogee, — East  pond,  at  the  head  of  Salmon  Falls  river,  having 
the  same  altitude  with  this  lake,  namely,  500  feet  above  the  sea. 

The  drainage  areas  on  either  side  of  our  river  valleys  are  specially 
favorable  for  the  provision  of  a  large  and  comparatively  constant  water 
supply.  With  the  exception  of  our  mountains,  already  noticed  in  their 
relation  to  our  water-power,  the  narrow  intervals  and  alluvial  plains  in  the 
valleys  of  our  largest  rivers,  and  the  level  portions  of  eastern  Rocking- 
ham  county,  our  whole  state  is  covered  with  irregularly  scattered  ridges 
of  hills.  The  rainfall  is  gathered  into  .our  streams  and  lakes  without  the 
large  waste  from  evaporation  and  infiltration  which  takes  place  upon 
.  comparatively  level  water-sheds,  such  as  those  of  a  large  portion  of  the 
West.  At  the  same  time,  the  surface  being  only  moderately  broken,  con 
sisting  of  wide  swells  of  hilly  country  to  a  large  extent  covered  with 
forest,  the  drainage  from  rains  is  not  too  sudden,  so  as  to  turn  our  rivers 
into  torrents  which  cannot  be  used  in  passing,  and  leave  nothing  behind. 
This  variety  of  local  elevations  and  depressions  is  of  still  further  impor 
tance,  since  it  affords  room  for  the  natural  formation  of  invaluable  storage 
basins  of  reserved  water-power. 


324  PHYSICAL    GEOGRAPHY. 

No  feature  in  the  physical  geography  of  a  country  is  of  greater  impor 
tance  in  a  consideration  of  its  water-power  than  the  number,  size,  and 
distribution  of  its  lakes  and  ponds,  and  the  adaptation  of  its  surface  for 
the  construction  of  artificial  reservoirs,  and  for  increasing  the  capacity 
of  those  which  have  been  naturally  formed.  The  importance  of  this 
appears  when  it  is  remembered  that  water-power  is  suitable  for  extensive 
manufacturing,  where  large  amounts  of  capital  are  invested,  only  in  pro 
portion  as  it  is  constant  and  reliable  at  all  seasons  of  the  year.  It  may  be 
employed  for  local  convenience  and  by  small  establishments,  even  though 
it  be  variable  at  different  seasons,  and  its  use  wholly  suspended  during 
the  driest  portion  of  the  year ;  but  it  is  only  when  a  constant  supply  of 
water-power  can  be  depended  upon,  that  it  is  capable  of  being  advan 
tageously  employed  by  large  manufacturing  corporations, — the  greater 
cheapness  of  water-power,  as  compared  with  steam-power,  being  more 
than  counter-balanced  if  business  must  be  interrupted  and  capital  lie 
idle  because  of  the  failure  of  streams.  By  lakes,  ponds,  and  artificial 
reservoirs,  the  surplus  of  heavy  rains  and  of  snow  melting  is  stored  up 
in  the  season  of  excess  against  the  season  of  dearth.  Our  natural  reser 
voirs  are  of  a  capacity,  too,  which  man  would  not  presume  to  imitate  by 
artificial  constructions,  being  also  provided  almost  free  of  cost,  and  capa 
ble  of  being  put  to  actual  use  with  insignificant  outlay. 

In  our  climate  the  need  of  a  reserved  water  supply  is  likely  to  be 
experienced  at  two  seasons  of  drouth, — in  midsummer,  and,  to  a  less 
degree,  in  midwinter.  Although  the  amount  of  rainfall  for  the  different 
quarters  of  the  year  is  nearly  equal,  the  increased  heat  of  summer  and 
consequent  evaporation,  together  with  the  fact  that  our  summer  rainfall 
is  to  a  considerable  extent  from  showers,  and  subject  to  greater  variable 
ness  than  that  of  any  other  season,  usually  cause  our  streams  to  reach 
their  lowest  point  at  some  time  during  the  last  part  of  summer, — the  period 
of  drouth  being  in  some  years  protracted,  in  others  scarcely  noticeable  or 
wholly  wanting.  In  winter,  on  the  other  hand,  precipitation  takes  place 
largely  in  the  form  of  snow.  The  ground  itself,  in  all  its  upper  stratum, 
is  also  frozen  solid,  and  yields  but  small  contributions  to  the  streams. 
The  value  of  reservoirs  to  provide  a  supply  against  the  contingency  of 
want  at  these  seasons  can  scarcely  be  over-estimated.  By  these  the 
regulation  of  the  water  supply  is  under  the  control  of  the  consumer,  and 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  325 

not  dependent  upon  the  caprices  of  a  variable  climate,  which,  by  proving 
unfavorable,  would  bring  great  inconvenience  and  loss. 

Lakes  and  reservoirs  are  also  of  great  value  in  lessening  the  frequency 
and  violence  of  freshets.  By  their  storage  of  water,  in  floods  and  snow- 
meltings,  they  reduce  the  volume  of  streams  at  these  times,  causing  a 
comparatively  moderate  rise  of  surface.  Manufacturing  establishments, 
built  upon  rivers  subject  to  heavy  floods,  have  to  be  constructed  of  great 
strength  and  with  much  care  to  withstand  the  water,  and,  if  so  placed  as 
to  be  secure  against  the  overflow  of  freshets,  are  often  too  high  for 
advantageous  use  at  the  ordinary  stage  of  water.  The  equability  of 
volume  in  our  rivers  is  not  less  important  as  insuring  the  security  of 
property  invested,  than  it  is  in  making  the  investment  certain  of  a  profit 
able  return. 

A  further  consideration  of  importance  is,  that  the  water  of  lakes  and 
ponds  is  so  warm  in  winter,  that  mills  near  them  and  fed  by  them  expe 
rience  no  trouble  from  the  formation  of  ice  about  their  gate-ways  and 
wheels,  even  during  the  severest  cold.  Only  their  upper  strata  sink 
below  39°  in  midwinter,  the  deeper  portion  being  so  protected  by  the 
non-conducting  mantle  of  ice,  that  during  the  longest  winter  the  general 
temperature  remains  far  above  the  freezing  point. 

The  altitude  of  our  lakes  and  ponds  above  the  sea  should  also  be 
noticed.  The  supply  which  they  are  capable  of  furnishing  in  a  drouth  is 
of  equal  benefit  to  all  the  water-powers  situated  below  them  on  their  path 
way  to  the  sea.  This  enables  a  large  number  of  interested  companies  to 
enter  into  combination  for  the  improvement  of  these  natural  storage 
basins,  most  of  which  are  so  situated  that  the  lowering  of  their  outlets, 
or  the  erection  of  dams  at  a  comparatively  small  outlay,  would  double  or 
treble  their  value.  The  expense  of  such  improvements  would  be  divided 
among  a  large  number,  each  of  whom  would  receive  the  full  advantage  of 
the  increased  water  supply.  A  large  number  of  small  ponds  will  also  be 
improved  for  the  same  object  by  proprietors  on  their  outlets,  thereby 
increasing  at  the  same  time  the  capacity  of  the  larger  powers  below. 

The  average  depth  of  reserve,  that  with  a  reasonable  outlay  could  be 
retained  upon  the  surface  of  our  lakes  and  ponds  for  use  during  the  dry 
season  in  each  year, 'would  probably  not  be  less  than  eight  feet,  while  the 
natural  low  run  of  the  streams  would  be  more  than  doubled.  Indeed, 


326  PHYSICAL    GEOGRAPHY. 

the  proportion  of  reservoir  water  used  by  large  manufactories  is  in  many 
cases  eighty  or  ninety  per  cent,  of  the  whole  amount  during  the  drier 
season  of  the  year.  It  is  easy  to  see,  therefore,  how  great  an  advantage 
our  water-power  has  in  comparison  with  any  which  is  obliged  to  rely 
upon  the  natural  flow  of  the  streams,  or,  if  supplied  with  reservoirs  at  all, 
has  to  depend  on  artificial  constructions  of  comparatively  great  cost  and 
limited  capacity. 

RAINFALL  AND  EVAPORATION. 

A  previous  chapter  of  this  report  has  been  devoted  to  the  general  con 
sideration  of  the  climate  of  New  Hampshire :  reference  must  be  made  to 
this  for  statistics  and  meteorological  tables.  It  is  proposed  to  consider 
briefly  in  this  place  the  rainfall  and  temperature  of  the  state,  as  related 
to  the  volume  and  constancy  of  our  rivers. 

The  rainfall  of  New  Hampshire,  as  we  have  already  noticed,  is  consid 
erably  in  excess  of  the  normal  amount.  From  a  comparison  of  the 
records  of  the  Smithsonian  Institution,  it  appears  that  the  average  rain 
fall  for  the  same  latitude  westward  to  the  Missouri  river  is  not  more  than 
three  fourths  of  the  average  amount  which  we  receive.  A  like  compari 
son  with  places  south  of  us  along  the  Atlantic  slope  shows  that  their 
annual  rainfall  also  is  less  than  that  of  New  Hampshire.  The  difference, 
however,  is  small ;  but  the  comparison  is  remarkable,  since  these  places 
are  entitled  upon  general  principles  to  a  considerably  larger  rainfall  than 
our  state.  This  deviation  from  the  general  law  of  distribution  becomes 
intelligible  when  the  local  conditions  are  taken  into  account,  namely,  the 
cold  ocean  currents  north-east  of  us  and  along  our  shores,  the  consequent 
low  temperature,  and  its  influence  upon  the  storms  which  sweep  over  us. 
The  precipitation  of  moisture  throughout  the  year  is  also  remarkably 
uniform,  the  total  amount  being  almost  equally  divided  between  the  four 
seasons.  The  practical  consequence  of  this  distribution  of  rainfall  is, 
that  our  state  enjoys  comparative  security  from  the  two  great  obstacles 
to  the  successful  employment  of  water-power,  freshet  and  drouth. 

These  favorable  conditions  are  still  further  promoted  by  our  tempera 
ture.  In  no  other  part  of  the  Northern  Hemisphere,  except  north-eastern 
China,  does  the  isothermal  line,  which  represents  the  mean  temperature 
of  our  state,  sink  so  near  to  the  equator, — that  is,  our  average  temper- 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  327 

ature  is  unusually  low  for  the  latitude.  The  line  of  the  same  average 
temperature  for  the  year  crosses  Europe  several  hundred  miles  farther 
north,  corresponding  to  the  mouth  of  the  St.  Lawrence  and  the  southern 
coast  of  Labrador.  Thus  while  New  Hampshire  cannot  be  declared  to 
be  cold  in  respect  to  comfortable  habitableness  and  capacity  of  vegetable 
production,  it  is  so  in  a  relative  sense,  and  as  compared  with  other  coun 
tries  no  further  removed  towards  the  poles. 

This  is  mainly  caused  by  the  cold  oceanic  current  already  referred  to, 
which  the  Arctic  sea  pours  forth  upon  the  north-eastern  shores  of  our 
continent.  This  effect  is  exerted  on  so  grand  a  scale  that  the  whole 
north-east  portion  of  North  America  is  constituted  a  geographic  region 
of  relatively  low  temperature.  The  focus  of  this  district  is  at  the  north 
east  corner  of  Hudson's  bay,  its  relative  deficiency  of  heat  being  13°. 
The  temperature  of  all  adjacent  regions  is  lower  than  that  due  to  the 
latitude  in  proportion  to  their  proximity  to  this  point.  Thus,  at  Quebec 
the  deficiency  is  stated  by  Wells  as  nearly  7°,  and  at  New  York,  4°; 
throughout  New  Hampshire  it  is  therefore  about  5°.  5, — that  is,  our  mean 
temperature  is  what  might  be  expected  were  our  geographic  position  five 
degrees  farther  north.  The  temperature  of  Europe,  on  the  other  hand, 
is  much  warmer  than  would  be  expected  for  the  latitude,  owing  to  the 
warm  current  of  the  Gulf  Stream,  which  is  constantly  pouring  upon  its 
shores. 

This  comparatively  low  temperature  of  our  state  largely  increases  the 
volume  of  its  streams.  This  is  effected,  first,  by  the  condensation  of  a 
large  amount  of  moisture  from  the  warm  south  and  south-west  winds, 
inducing  a  more  abundant  rainfall  than  could  be  looked  for  in  our  lati 
tude  and  upon  the  lee  side  of  the  continent ;  and,  secondly,  by  diminish 
ing  the  waste  of  water  from  evaporation,  preserving  consequently  a  larger 
proportion  for  removal  by  rivers.  Having  already  noticed  the  conditions 
which  are  concerned  in  the  first  of  these  results,  it  remains  to  speak  here 
of  the  relation  of  evaporation  to  water-power,  and  the  modification  of 
this  influence  from  our  comparatively  low  temperature. 

Of  the  total  rainfall  of  the  state,  probably  sixty  per  cent,  is  removed 
by  evaporation  from  our  surface  before  it  reaches  the  sea.  In  the  case 
of  various  reservoirs,  where  an  exact  measurement  of  this  proportion 
could  be  taken,  the  evaporation  from  the  drainage  area  has  been  found 


328  PHYSICAL    GEOGRAPHY. 

to  vary  from  fifty  to  sixty  per  cent,  of  the  total  rainfall.  From  England 
and  Ireland  the  amount  of  evaporation  is  estimated  as  two  thirds ;  from 
the  Ohio  and  upper  Mississippi  river  basins,  three  fourths ;  from  the  basins 
of  the  Missouri,  Arkansas,  and  Red  rivers,  five  sixths  of  the  whole  rain 
fall.*  The  larger  proportion  west  of  the  Mississippi  is  due  to  the  preva 
lence  of  winds  already  reduced  to  dryness  by  passage  over  mountain 
ranges,  and  still  more  inclined  by  the  increased  temperature  of  this 
region  to  absorb  rather  than  impart  moisture.  In  the  Ohio  and  upper 
Mississippi  basins  the  mean  temperature  is  higher  than  with  us,  and  the 
air  more  drying  throughout  the  year ;  the  surface,  also,  is  far  less  favora 
ble  for  drainage  than  in  our  own  state.  In  a  comparison  with  the  British 
Isles,  it  is  to  be  noted  that  our  mean  annual  temperature  is  several 
degrees  lower  than  theirs,  our  winters  sealed  by  frost  against  evaporation 
while  theirs  are  open,  and  our  surfaces  to  a  much  larger  extent  forest 
clad,  producing  probably  with  us  a  considerably  lower  proportion  of 
evaporation. 

The  tendency  to  evaporation  is  of  course  less  in  proportion  as  the 
winds  which  reach  our  area  are  charged  with  moisture.  Our  position  on 
the  coast  is  favorable  in  this  regard.  It  is  not,  however,  the  actual 
amount  of  moisture  which  air  contains  that  renders  it  moist,  but  the  rela 
tion  between  that  amount  and  the  amount  which  is  capable  of  being 
held  in  suspension.  Although  the  south-west  storms  which  sweep  over 
us,  laden  with  the  evaporation  of  the  Mexican  gulf,  have  become  de 
prived  of  much  of  their  moisture  before  reaching  us,  they  are  still  as 
thoroughly  saturated  as  at  their  start,  having  become  cooled,  and  conse 
quently  capable  of  holding  less  moisture  in  the  same  proportion  as  they 
have  given  it  up.  As  we  have  seen,  this  cooling  process  becomes  more 
rapid  as  these  winds  reach  us,  on  account  of  our  unusually  low  tempera 
ture,  giving  them  great  relative  humidity,  with  the  results  of  increased 
rainfall  and  lessened  evaporation.  Thus  the  effect  of  our  temperature  is 
to  give  us  relatively  moist  instead  of  drying  winds,  making  the  loss  by 
evaporation  from  the  surface  a  comparatively  low  proportion. 

The  average  summer  temperature  of  New  Hampshire  is  several  degrees 
lower  than  that  of  places  of  the  same  latitude  farther  west,  while  a  still 
greater  difference  is  exhibited  in  a  comparison  with  the  middle  and 

*  Wells 's  Water  Power  of  Maim,  1869,  p.  52. 


RIVER    SYSTEMS    OF    NEW    HAMPSHIRE.  329 

southern  states.  Our  chances  of  water  dearth  occasioned  by  summer 
heat  are  thus  greatly  diminished  as  compared  with  other  sections  of  the 
country. 

Our  winter  temperature  is  more  nearly  like  that  of  the  same  latitude 
westward,  being  indeed  less  severe,  the  neighborhood  of  the  sea  having 
the  effect  to  lessen  the  extremes  of  our  temperature,  which  is  lower  in 
summer,  and  on  an  average  for  the  year,  but  nearly  the  same  in  winter. 
Our  mean  winter  temperature,  however,  falls  considerably  below  the 
freezing  point  of  water.  The  ground,  therefore,  with  its  contained  water, 
tends  to  freeze  solid  to  a  considerable  depth,  thereby  lessening  the  supply 
of  streams.  Much  of  the  surface  water  upon  the  drainage  sheds  through 
out  this  season  is  changed  to  ice.  The  precipitation  also  is  mainly  in  the 
form  of  snow.  But  these  circumstances,  which  seem  to  threaten  water 
dearth,  never  act  to  their  full  extent  in  combination  to  reduce  river 
supply.  When  a  large  depth  of  snow  falls  the  ground  does  not  freeze 
deeply,  and  continues  therefore  to  give  forth  the  reserved  abundance  of 
the  autumn  rains.  Nor  does  the  severity  of  the  temperature  often  last 
many  weeks  without  such  intervals  as  admit  of  rains  and  the  thawing  of 
part  of  the  accumulated  snow,  with  sufficient  time  for  drainage,  by  which 
the  water  supply  is  reinforced  and  the  lakes  and  reservoirs  filled.  Thus, 
while  our  streams  tend  to  run  low  in  winter,  they  are  still  almost  always 
prevented  from  reaching  so  low  a  point  as  in  the  heat  of  summer.* 

The  frequent  thaws  of  winter  also  prevent  the  accumulation  of  snow 
from  being  wholly  reserved  for  the  melting  of  spring.  The  disappearance 
of  the  snow  remaining  at  that  season,  however,  sometimes  attended  with 
heavy  rains,  usually  produces  the  highest  stage  of  water  for  the  year.  A 
few  of  the  conditions  which  modify  this  result  deserve  to  be  considered. 
During  the  winter  the  snow  generally  becomes  solidified,  especially  in  its 
lower  portions,  almost  to  ice,  and  in  this  form  it  disappears  but  slowly 
before  the  advancing  heat  of  the  year.  The  ground,  even  if  frozen  before 
snowfall,  is  usually  thawed  out  beneath  the  snow  of  winter,  and  becomes 
a  reservoir  for  a  large  amount  of  water,  thus  retarding  the  discharge  into 
the  rivers.  For  these  reasons,  the  accumulations  of  winter  go  off  with 

*  Reference  to  charts  illustrating  isothermal  lines  and  rainfall  will  show  that  the  Merrimack  valley  is  the 
warmest  area  in  the  state,  and,  also,  that  it  receives  the  most  rain.  Combining  with  these  the  constancy  of  flow 
caused  by  the  large  lake  reservoirs,  and  it  is  clear  that  the  Merrimack  river  is  superior  to  the  Connecticut,  if  not 
to  any  stream  in  the  country,  for  its  capabilities  for  driving  machinery.  C.  H.  H.

less  swelling  of  the  streams  than  is  experienced  farther  south  and  in  the 
interior,  where  the  depth  of  snow  is  less,  but  where  the  spring  heat  comes 
on  more  suddenly,  and  without  the  moderating  influence  of  cold  sea 
winds. 

The  effect  of  summer  temperature,  also,  although  sufficient  to  produce 
the  lowest  run  in  our  streams  for  the  year,  is  yet  far  different  from  that 
experienced  in  many  portions  of  our  country.  No  such  thing  is  known 
in  New  Hampshire  as  the  drying  up  of  streams,  draining  hundreds  of 
square  miles  of  territory,  into  chains  of  half-stagnant  pools,  their  beds 
turned  into  wastes  of  fissured,  sun-baked  mud,  strewn  with  the  stumps 
and  driftwood  of  freshets,  leaving  long  bridges  stretching  across  dry 
land,  where,  at  the  spring  flood,  a  torrent  twenty  feet  deep  fills  the  entire 
channel. 

In  conclusion,  it  appears  that  the  temperature  of  the  state,  on  the 
whole,  influences  very  favorably  both  the  volume  and  constancy  of  our 
rivers.  The  mean  for  the  year  is  comparatively  low,  and  the  loss  from 
evaporation  is  therefore  of  necessity  comparatively  small.  Our  relative 
advantage  in  this  respect  is  also  greatest  in  the  abatement  of  the  drouth 
of  summer,  which  everywhere  fixes  the  limit  of  the  capacity  of  water- 
power.

CHAPTER    XII. 

THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE. 


BY    SAMUEL    H.    SCUDDER. 


I.  GENERAL  CONSIDERATIONS. 

>ROBABLY  no  state  in  the  Union  presents  so  striking  a  variety  in 
its  animal  life  as  New  Hampshire.  Its  northern  and  southern 
portions  belong  to  distinct  continental  faunas ;  above  the  forest  growth 
of  its  colder  region  rise  some  of  the  highest  elevations  east  of  the  Rocky 
Mountains,  and  these  bleak  altitudes  support  a  vegetation  and  an  assem 
blage  of  animals  intimately  resembling  those  of  Labrador  and  Greenland, 
while  sixty  miles  to  the  south  flourish  animals  characteristic  of  sub 
tropical  climes. 

In  the  northern  hemisphere,  rivers  flowing  south  always  exert  an 
influence  upon  the  character  of  the  inhabitants  upon  its  banks ;  and  the 
Connecticut,  although  navigable  but  fifty  miles,  is  no  exception  to  the 
rule.  At  its  southern  extremity  it  reaches  a  warm  coast  and  a  latitude 
where  numerous  insects  occur,  whose  true  metropolis  is  found  in  the 
Carolinas  and  Floridas.  Many  of  these,  following  the-  course  of  the  river, 
with  its  warm,  moist  banks,  penetrate  into  the  heart  of  the  country; 
some  are  found  in  central  Massachusetts,  a  few  in  southern  Vermont 
and  New  Hampshire,  and  one  or  two  are  found  even  in  the  latitude  of  the 
White  Mountains.  It  is  therefore  especially  interesting  to  consider  the 
distribution  of  a  few  groups  of  insects  in  New  Hampshire. 


33  2  PHYSICAL    GEOGRAPHY. 

In  1854,  Prof.  L.  Agassiz  made  the  first  attempt*  to  divide  North 
America  into  several  zoological  areas ;  and,  on  a  rude  map  accompanying 
his  sketch,  he  draws  a  line  in  an  east-westerly  direction,  which  passes 
through  New  Hampshire.  The  two  great  regions  thus  separated  he 
names  the  Canadian  and  Alleghanian  faunas. 

In  1859,  Dr.  J-  L.  LeConte  divided  the  United  States  into  a  number  of 
"entomological  provinces;"!  and  the  "northern"  and  "middle"  provinces 
of  his  "Atlantic  district"  were  separated  by  a  line  which  passed  through 
the  southern  half  of  New  Hampshire. 

In  1863,  Prof.  A.  E.  Verrill  also  pointed  out  that  the  dividing  line  of  the 
Canadian  and  Alleghanian  faunas  cut  New  Hampshire  in  two,$  and  three 
years  later  he  defined  the  limits  more  exactly  as  "coincident  with  a  line 
which  shall  indicate  a  mean  temperature  of  50°  Fahrenheit  during  the 
months  of  April,  May,  and  June;"  and,  in  describing  its  course,  says, — 
"  It  passes  south  of  Moosehead  and  Umbagog  lakes,  but  rises  somewhat 
northward  along  the  Androscoggin  valley,  thence  it  passes  southward  of 
the  White  Mountains,  through  the  vicinity  of  Conway,  N.  H.  It  bends 
northward  again  up  the  Connecticut  valley  as  far  as  Craf tsbury,  Vt,  where 
the  mean  temperature  is  50°  91."  || 

Mr.  J.  A.  Allen  has  recently  discussed  the  areas  of  the  faunas  of  east 
ern  North  America ;  and,  in  his  description  of  the  northern  boundary  of 
the  Alleghanian  fauna,  says  the  line  "follows  the  northern  boundaries  of 
the  lowlands  through  southern  Maine  and  southern  New  Hampshire.  In 
the  Connecticut  valley  it  rises  farther  to  the  northward,  and,  in  its  south 
ern  descent,  skirts  the  eastern  base  of  the  Green  Mountains."  § 

Both  of  these  latter  writers  base  their  conclusions  upon  the  study  of 
birds  during  breeding  season,  as  first  suggested  by  Prof.  Verrill,  in  1 866,  in 
the  paper  from  which  we  have  quoted,  and  where  he  further  writes, — "From 
this  remarkable  coincidence  between  this  system  of  lines  of  temperature 
of  the  months  of  spring  and  early  summer,  with  what  had  been  already 
observed  in  the  actual  distribution  of  birds,  we  must  necessarily  infer

THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  333 

that  they  are  chiefly  influenced,  so  far  as  latitude  is  concerned,  by  the 
temperature  of  the  breeding  season  .  .  .  ;  whether  a  similar  law  con 
trols  the  distribution  of  mammalia,  reptiles,  insects,  etc.,  can  only  be 
determined  by  further  investigation." 

Since  insects  are  not  regularly  migratory  animals ;  as  several  genera 
tions  frequently  succeed  each  other  during  a  single  season  ;  and,  as  the 
winter  is  passed  in  very  various  conditions,  we  can  hardly  expect  their 
distribution  to  follow  exactly  that  of  birds.  Various  causes  may  modify 
unequally  the  distribution  of  insects  belonging  to  a  certain  group :  too 
intense  cold  in  our  arctic  winters ;  the  lack  of  snow  during  a  less  severe 
season ;  too  excessive  heat  or  too  long  a  drouth  in  midsummer ;  or,  too 
sudden  changes  of  temperature  at  critical  periods.  Taking  our  butter 
flies  only,  they  may  be  found  at  every  season  of  the  year,  even  in  mid 
winter,  of  one  species  or  another,  in  every  stage  of  existence,  from  the 
egg,  through  all  the  larval  periods  and  the  chrysalis,  to  the  imago.  The 
distribution  of  butterflies  is  therefore  much  more  complicated  than  that 
of  birds,  whose  early  stages  are  always  passed  in  comparatively  warm 
weather,  under  the  guardianship  of  the  mother;  and,  if  more  than  one 
brood  appears  during  a  season,  the  second  is  only  the  produce  of  the 
same  pair  that  raised  the  first. 

It  is  nevertheless  true  that  the  distribution  of  insects  over  continental 
areas  coincides  in  a  remarkable  way  with  that  of  birds.  The  northern 
limits  of  the  Alleghanian  fauna,  as  laid  down  by  Verrill,  agree  very 
fairly  with  the  northern  boundary  of  the  belt  colored  blue  on  Plate  B ; 
and  this  probably  indicates  pretty  accurately  the  southern  limit  of  Cyclo- 
pides  Mandan  and  the  northern  limit  of  Mcgisto  Eiiryttts,  Grapta  comma, 
Argynnis  Cybcle,  A.  Aphrodite,  and  EupJiyes  Mctacomet.  It  may  be  ques 
tioned,  however,  whether,  as  far  as  butterflies  are  concerned,  this  can  really 
be  considered  the  northern  limit  of  the  Alleghanian  fauna.  If  we  trace 
upon  a  map  of  the  state  the  northern  limits  of  the  several  Alleghanian 
butterflies  and  the  southern  limits  of  the  Canadian,  they  will  be  found  to 
mingle  in  a  broad  belt  of  country,  which  includes  all  the  colored  portions 
of  Plate  B,.  The  northernmost  Alleghanian  and  southernmost  Canadian 
species  gradually  decrease  in  numbers  away  from  their  metropolis,  and 
become  confined  to  increasingly  lower  or  higher  altitudes  in  this  belt, 
according  as  they  are  Alleghanian  or  Canadian  forms. 


334  PHYSICAL   GEOGRAPHY. 

Mr.  Allen's  location  of  the  dividing  line  between  the  Alleghanian  and 
Canadian  faunas,  though  rather  vaguely  stated,  seems  to  correspond 
better  with  the  distribution  of  butterflies,  though  it  is  perhaps  still  too 
far  north ;  and  I  have  colored  a  narrow  band  red  on  Plate  B,  which  will 
indicate  more  exactly  the  limitation  which  seems  to  accord  best  with  the 
facts  at  my  command.  This  band,  striking  the  Maine  boundary  opposite 
the  lower  extremity  of  Lake  Winnipiseogee,  runs  in  a  south-westerly 
direction  nearly  parallel  with  the  coast  line  of  Maine,  until  it  reaches  the 
vicinity  of  the  Monadnock  mountain  (Hillsborough  county),  and  then 
turns  sharply  upward  and  strikes  the  Connecticut  river  at  the  highlands 
about  Claremont.  In  the  neighborhood  of  this  band  (sometimes  closely 
confined  to  it)  are  the  southern  limits  of  such  Canadian  butterflies  as 
Minois  Alope,  and  the  northern  limits  of  such  Alleghanian  butterflies  as 
Basilarchia  Astyanax,  G  rapt  a  intcrrogationis,  Vanessa  Hunt  era,  Speyeria 
Idalia,  Pterourus  Troilns,  Erynnis  Juvenalis,  AntJiomaster  Leonardns, 
and  Limochores  Manataaqua;  other  species,  including  northern  types  like 
Grapta  Faunas  and  Argynnis  Atlantis,  and  southern  types,  such  as  Epar- 
gyreus  Tityrus  and  PampJnla  Sassacus,  find  their  southern  or  northern 
limits,  as  the  case  may  be,  within  other  portions  of  the  broad  blue  belt ; 
while,  again,  some  Alleghanian  species,  such  as  AcJialarus  Lycidas,  PJw- 
lisora  Catullus,  Amblyscirtcs  vialis,  Ocytes  Metea,  and  Poancs  Massasoit, 
find  their  northern  limit  at  the  southern  boundary  of  this  belt ;  and  some 
Canadian  species,  such  as  Argus  Eurydice  and  Aglais  Milberti,  find  at 
this  same  point  their  southern  limit. 

It  is  plain  that  somewhere  within  this  blue  belt  the  dividing  line  between 
the  Canadian  and  Alleghanian  faunas  must  be  drawn ;  and  it  will  proba 
bly  prove  difficult  to  discover  any  more  exact  boundary  than  this,  for  we 
should  certainly  expect  an  interdigitation  of  forms  peculiar  to  the  two 
faunas  over  some  common  area;  and  it  is  only  by  direct  study  of  the 
comparative  abundance  or  rarity  of  very  many  species  of  animals  within 
this  broad  belt  that  any  more  exact  limitation  can  be  obtained.  The 
local  zoologists  of  New  Hampshire  can  render  science  an  important  ser 
vice  by  a  careful  record  of  such  facts  in  as  many  distinct  localities  as 
possible ;  only  it  is  essential  that  such  observations  be  continued  through 
several  successive  seasons  (best,  for  a  decade),  for  the  comparative  abun 
dance  of  any  one  species,  in  any  one  locality,  depends  upon  a  variable

climate,  the  antagonism  of  other  insects,  and  many  other  causes  still 
unknown. 

It  may  be  well  to  enter  with  more  detail  upon  the  probable  limits  of 
the  belt  colored  blue  on  Plate  B.  At  the  north,  it  enters  New  Hampshire 
from  Maine  near  the  range  of  hills  lying  east  of  Pinkham's  notch, 
and  comes  from  the  direction  of  Bethel  or  Norway,  Me.  That  the  latter 
town  lies  near  the  boundary  between  the  Alleghanian  and  Canadian 
faunas  is  evident  from  the  extensive  collections  of  Messrs.  Verrill  and 
Smith.  From  this  point  it  runs  between  Bartlett  and  Conway  toward 
Plymouth,  passing  just  north  of  the  latter  town,  following  up  Baker's 
river  toward  the  Connecticut,  and  only  crossing  the  latter  stream  at  some 
distance  above  Wells  river.  At  the  north,  on  either  side  of  the  White 
Mountains,  the  Alleghanian  fauna  extends  along  the  river  bottoms  of  the 
Androscoggin,  the  Connecticut,  and  even  the  Ammonoosuc,  but  too  nar 
rowly  to  be  traced  upon  our  map.  Less  is  known  about  the  southern 
boundary  of  the  band  at  its  eastern  extremity,  but  it  must  enter  the  state 
between  Dover  and  the  sea,  and  it  continues  in  a  nearly  straight  line 
through  Milford  to  Warwick,  Mass.  Here  it  turns  upward  and  toward 
the  Connecticut,  crossing  the  river  certainly  above  Brattleborough,  Vt., 
and  perhaps  as  high  as  Walpole,  N.  H.,  where  Mr.  S.  I.  Smith  has  even 
taken  a  specimen  of  Laertias  PJiilcnor. 

Thus  far  our  examples  have  been  wholly  drawn  from  among  the  butter 
flies,  as  the  best  known  group  of  insects ;  but  our  knowledge  of  the 
Orthoptera  is  sufficiently  advanced  to  show  that  the  facts  of  their  distri 
bution  do  not  militate  against  the  conclusions  drawn  from  the  study  of 
the  butterflies.  Among  the  Orthoptera  of  the  Alleghanian  fauna,  Gryl- 
lotalpa  borealis,  CEcantJius  nivctis,  Phylloptera  oblongifolia,  Thyreonotus 
dorsalis,  CJirysocJiraon  viridis,  and  Diaplieromera  femorata  appear  to 
reach  only  the  southern  limits  of  our  blue  belt ;  while  TragoccpJiala  sor- 
dida,  CEdipoda  Carolina,  Hippiscus  phoenicopterus,  H,  mgosa,  the  different 
Tettigideans  (perhaps  with  the  exception  of  BatracJiidca  cristata)  and 
Labia  minuta  probably  extend  to  its  northern  boundaries.  On  the  other 
hand,  among  the  insects  of  the  Canadian  fauna,  CJilocaltis  conspersa, 
Arcyptera  lineata,  A.  gracilis,  Trimcrotropis  vcrruculata,  and  Cammula 
pclludda  find  their  southern  limit  at  or  near  the  southern  extremity  of 
the  blue  belt ;  the  latter  species  also  occurs  on  high  ground  farther  south. 


336  PHYSICAL    GEOGRAPHY. 

Pezotcttix  borealis  and  P.  manca  do  not  extend  below  the  uppermost 
boundaries  of  the  blue  belt ;  while,  among  Alleghanian  species,  Trimcro- 
tropis  czgnalis,  ArpJiia  xantlioptera,  and  A.  sulphured  are  limited  on  the 
north  by  the  red  band,  the  first  perhaps  extending  somewhat  farther. 

But  the  principal  interest  attaching  to  the  distribution  of  insects  in 
New  Hampshire  is  through  their  relation  to  the  White  Mountains.  These 
mountains  are  situated  next  the  southern  boundary  of  the  Canadian 
fauna,  and  their  valleys,  as  well  as  the  lower  wooded  portions  of  their 
slopes,  are  peopled  with  representatives  of  this  region ;  but  their  peaks 
rise  from  above  the  limit  of  forest  growth,  and  maintain  a  fauna  and  flora 
very  distinct  from  those  below. 

It  has  long  been  known  that  in  ascending  lofty  mountains  within  the 
warm  or  temperate  regions,  one  passes  successively  over  areas  exhibiting 
in  their  vegetation  distinct  features,  with  an  ever  increasing  resemblance 
to  more  northern  floras.  The  European  Alps  have  furnished  a  field  for 
extensive  investigations ;  and  their  sides  have  been  mapped  into  distinct 
zones,  called,  on  an  ascending  scale,  the  mountain,  the  sub-alpine,  and  the 
alpine  regions.  These  regions  have  been  recognized  and  applied  to 
similar  phenomena  elsewhere,  and  are  in  general  use.  It  has  also  been 
noticed  that  the  distribution  of  animals  upon  mountain  summits  corre 
sponds  with  that  of  plants. 

So  far  as  plants  are  concerned,  no  distinctive  alpine  and  sub-alpine 
regions  have  yet  been  recognized  in  the  White  Mountains.  Dr.  Asa 
Gray,  it  is  true,  in  his  statistics  of  the  flora  of  the  northern  United 
States,*  gives  separate  and  extended  lists  of  alpine  and  sub-alpine  plants ; 
but  the  only  distinction  made  between  the  two  is,  that  the  former  are 
found  only  in  "our  small  alpine  region"  (in  which  he  includes  all  the 
treeless  summits  of  the  White  Mountains),  and  the  latter  "occur  mainly  in 
our  alpine  region,  but  are  also  found  decidedly  out  of  it ;"  so  that  the  lists 
do  not  separate  plants  of  distinct  alpine  and  sub-alpine  zones.  Prof.  E. 
Tuckerman,  in  a  very  interesting  article  upon  the  vegetation  of  the  White 
Mountains,!  says, — "Botanists  designate  the  highest  bald  district,  with

THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  337 

the  heads  of  ravines  descending  from  it,  as  the  alpine  region,  and  have 
sometimes  spoken  of  a  small  tract  intermediate  between  the  two,  but 
still  imperfectly  characterized,  as  the  sub-alpine  region;"  and  this  is  the 
most  definite  mention  of  a  sub-alpine  as  distinct  from  an  alpine  zone  yet 
made  by  botanists. 

More  than  ten  years  ago,  however,  I  pointed  out  *  that  two  distinct 
zones  of  life  existed  above  the  limits  of  forest  growth  in  the  White 
Mountains,  each  of  which  was  characterized  by  the  presence  of  distinct 
animals.  So  little  has  been  added  to  these  observations,  that  I  have 
incorporated  them  into  the  present  essay. 

One  feature  of  the  White  Mountain  vegetation  strikes  the  most  casual 
observer,  viz.,  the  abrupt  limit  of  the  forest  growth  upon  these  mountain 
slopes,  marking  a  very  natural  division  into  a  wooded  and  a  woodless  dis 
trict.  An  observant  eye  will  detect  in  the  latter  a  further  subdivision 
into  two  regions, — a  lower,  where  the  dwarfed  spruce,  struggling  upward, 
conceals  the  gray  rocks  by  a  covering  of  uniform  green,  broken  only  by 
the  land-slips  which  have  scarred  the  declivities  with  their  lengthened 
furrows,  or,  by  the  steeper  faces  of  precipices,  where  trees  obtain  no  foot 
hold  ;  and  an  upper,  much  more  restricted  area,  where  the  huge  blocks 
of  lichen-covered  stone  lie  piled  in  inextricable  confusion,  one  upon 
another,  or  have  their  interstices  filled  with  sedges,  which,  on  the  more 
level  spots,  occasionally  form  small  fields  like  pasture-land,  but  full  of  pit 
falls  and  irregularities. 

These  three  zones  (the  forest  district,  the  district  of  the  dwarfed  spruce, 
and  the  rocky  district)  exhibit  in  a  general  way  the  limits  of  the  moun 
tain,  the  sub-alpine,  and  the  alpine  regions ;  and  also  correspond,  in  the 
characteristics  of  their  inhabitants,  to  the  Canadian,  the  Hudsonian,  and 
the  sub-arctic  or  Labradorian  faunas.  They  do  not,  however,  correspond 
to  the  divisions  indicated  by  Tuckerman,  for  the  "heads  of  ravines"  and 
all  the  surrounding  districts  belong  to  the  sub-alpine  region,  while  the 
alpine  is  confined  to  the  topmost  areas  of  only  the  very  highest  peaks. 

The  separation  of  the  mountain  from  the  sub-alpine  region  is  well 
marked  by  the  limit  of  the  forest  growth,  and  this  is  so  abrupt  that  a 
narrow  belt  of  a  few  rods  is  usually  all  that  intervenes  between  the  spruce

of  one,  two,  or  three  feet  high  and  trees  available  for  the  market.  The 
limit  of  the  trees  is  not  wholly  dependent  upon  the  elevation  of  the  slope, 
but  is  partly  influenced  by  the  ravines,  and,  to  a  much  greater  extent,  by 
the  exposure  of  the  mountain  side,  which  causes  a  variation  of  from  one 
to  two  hundred  feet  in  altitude.  Upon  Mt.  Madison  and  the  north-western 
slope  of  Mt.  Washington,  the  forest  line,  according  to  the  measurements 
of  Prof.  Guyot,  reaches  the  height  of  4150  feet  above  the  sea,  and,  upon 
the  face  of  Mt.  Clinton,  which  has  a  westerly  exposure,  it  attains  an  eleva 
tion  of  4250 feet;  while,  again,  at  the  ledge  (the  most  northerly  extremity 
of  the  sub-alpine  region  on  Mt.  Washington),  its  limit  is  reached  at  about 
3900  feet.  The  alpine  region  occupies  the  summits  of  only  the  three 
highest  mountains,  being  limited  to  from  one  to  two  hundred  feet  of  the 
cones  of  Mts.  Adams  and  Jefferson,  and  some  seven  or  eight  hundred 
feet  of  Mt.  Washington. 

On  Plate  C  I  have  attempted  to  show  by  the  red  color  the  general  area 
of  the  alpine,  and  by  the  blue  the  limits  of  the  sub- alpine  region.  Stand 
ing  upon  the  summit  of  Mt.  Washington,  the  main  peak,  and  looking  at 
the  mountains  which  lie  to  the  north,  it  will  be  seen  that,  while  the  sub- 
alpine  region  follows  the  main  chain,  it  extends,  also,  a  short  distance 
along  the  ridge  running  eastwardly  from  the  peak  of  Mt.  Madison,  and 
to  a  much  greater  distance  north-eastwardly  from  Mt.  Washington,  in  the 
general  direction  of  the  carriage-road,  terminating,  at  a  lower  level  than 
usual,  at  the  ledge,  around  which  the  road  abruptly  turns  just  before  it 
enters  the  forest.  South  of  Mt.  Washington  there  are  two  ridges :  the 
more  prominent  and  longer  range,  whose  peaks  bear  the  names  of  Amer 
ican  statesmen,  trends  toward  the  south-west ;  the  other  continues  in  the 
direction  of  the  main  chain  lying  to  the  north  of  Mt.  Washington,  and  its 
northernmost  peaks  have  received  the  names  of  Davis's  and  Boott's  spurs. 
A  slight  abutment  to  Mt.  Washington  divides  the  angle  between  these 
two,  but  is  nearer  the  latter.  By  the  union  of  these  ridges,  at  their 
junction  with  Mt.  Washington,  there  is  formed  a  broad  plateau,  called 
Bigelow's  lawn,  sloping  gradually  away  to  the  south,  where  the  sub-alpine 
region  finds  its  widest  boundaries,  and  whose  southern  limits  I  have  not 
traced  as  carefully  as  upon  the  opposite  side  of  Mt.  Washington,  but  which 
must  have,  approximately,  the  extent  shown  upon  the  map.  Within  this 
sub-alpine  region,  which  includes  also  the  heads  of  all  the  deeper  ravines,

there  are  several  ponds  or  tarns  of  small  extent, — one  in  the  deep  gap 
between  Adams  and  Madison,  at  the  head  of  King's  ravine,  at  the  height 
of  4912  feet;  several  small  ones  upon  the  slopes  of  Adams  and  Jefferson; 
two  deeper  ones,  known  as  the  Lakes  of  the  Clouds,  the  highest  sources 
of  the  Ammonoosuc,  lying  at  the  base  of  Mt.  Monroe  on  the  Mt.  Wash 
ington  side ;  and  other  small  ones  on  the  south  side  of  Mt.  Monroe. 

The  alpine  zone  of  Adams  and  Jefferson  merely  encircles  their  sum 
mits;  that  of  Mt.  Washington  stretches  north-eastwardly  along  the  ridge 
which  extends  in  that  direction,  occupying  one  or  two  successively  lower 
plateaus ;  it  also  expands  upon  the  opposite  side  of  the  mountain,  over 
the  upper  portions  of  the  widely  extended  plateau  known  as  Bigelow's 
lawn,  but  it  scarcely  attains  the  Lakes  of  the  Clouds  upon  the  one  side, 
or  the  edge  of  Tuckerman's  ravine  upon  the  other. 

Within  the  limits  of  the  sub-alpine  region,  and  generally  preferring  its 
lower  to  its  tipper  levels,  we  find  a  butterfly  (Brenthis  Montinus)  and  a 
grasshopper  (Pezotcttix  glacialis),  which,  so  far  as  yet  known,  are  wholly 
or  almost  wholly  peculiar  to  this  region.  The  butterfly  has  been  taken 
in  scanty  numbers  but  at  various  localities,  such  as  the  summit  of  Mt. 
Madison,  the  plateaus  just  above  the  ledge,  the  gaps  between  Clay, 
Jefferson,  and  Adams,  the  head  of  Tuckerman's  ravine,  the  adjoining 
portions  of  Bigelow's  lawn,  and  the  further  extremity  of  the  sub-alpine 
belt  upon  the  summits  of  Mts.  Clinton  and  Pleasant;  it  has  also  been 
"seen"  on  the  top  of  Black  mountain  in  Thornton,  but  some  other  species 
of  Brenthis  might  easily  have  been  mistaken  for  this  ;  yet  it  will  probably 
be  found  upon  the  summits  of  moderately  high  and  barren  mountains  in 
the  neighborhood  of  the  White  Hills.  The  grasshopper  is  abundant 
upon  all  the  woodless  parts  of  Mt.  Madison,  especially  near  the  forest 
line ;  also,  at  and  above  the  ledge,  near  the  snow-bank  in  Tuckerman's 
ravine,  and  on  the  warm  hillsides  above  the  latter.  It  has  also  been 
taken  on  barren  hill-tops  near  Norway,  Me.,  and  will  doubtless  be  found 
in  any  similar  situation  in  the  vicinity  of  the  White  Mountain  range, 
especially  to  the  north. 

The  butterfly  belongs  to  a  genus  which  consists  of  several  groups, 
some  of  which  are  found  in  the  northern  temperate  regions  of  Europe 
and  America,  extending  also  into  the  colder  regions.  Others  inhabit  sub 
arctic  regions  and  high  altitudes;  while  one  group  extends  from  the

sub-arctic  into  the  arctic  zone,  and  contains  one  representative,  which  is 
the  most  northern  butterfly  known,  B.  polaris*  Our  White  Mountain 
butterfly  belongs  to  the  second  category,  having  its  representatives  on 
this  continent  in  the  Hudsonian  fauna.  It  is  very  closely  allied  to  two 
Hudsonian  species  (B.  Boisduvalii  and  B.  C/iariclca),  and  at  first  sight 
might  be  taken  for  them,  especially  for  the  former ;  but  repeated  exami 
nations  of  many  individuals  have  confirmed  my  first  impression  that 
they  were  distinct.  The  genus  Pezotettix,  to  which  the  grasshopper 
belongs,  is  not  so  strictly  northern  as  Brenthis,  but  has  several  represent 
atives  at  least  in  the  Hudsonian  fauna,  and,  like  Brenthis,  is  also  found  in 
the  alpine  elevations  of  Europe. 

But  even  the  narrow  limit  of  the  alpine  zone  of  the  White  Mountains 
claims  for  its  own  a  single  butterfly,  which  probably  has  a  more  restricted 
range  than  any  other  in  the  world.  One  may  search  the  season  through 
over  the  comparatively  vast  and  almost  equally  barren  elevations  within 
the  sub-alpine  district  of  the  White  Mountains,  and  fail  to  discover  more 
than  here  and  there  a  solitary  individual  whirled  by  fierce  blasts  down 
the  mountain  slopes,  while,  a  few  hundred  feet  above,  the  butterflies  swarm 
in  great  numbers.  Every  passage  of  the  sun  from  behind  a  cloud  brings 
them  out  in  scores,  and  they  may  often  be  captured  as  fast  as  they  can  be 
properly  secured.  The  contrast  between  the  occasional  and  unwilling 
visitor  in  the  sub-alpine  region,  and  the  swarms  which  flutter  about  the 
upper  plateaus,  is  most  significant.  Yet  the  Carices,  the  food-plant  of  the 
caterpillar,  are  quite  as  abundant  in  the  lower  regions  as  in  the  upper, 
even  to  the  species  C.  rigida,  upon  which  I  found  the  larva  feeding.  Now 
this  butterfly,  (Eneis  semidea,  belongs  to  a  genus  which  is  peculiar  to 
alpine  and  arctic  regions;  in  fact,  it  is  the  only  genus  of  butterflies  which 
is  exclusively  confined  to  them.  It  has  numerous  members,  both  in  this 
country  and  in  the  old  world.  One  is  confined  to  the  Alps  of  Europe ; 
most  of  the  European  species,  however,  are  found  only  in  the  extreme 
north.  The  genus  extends  across  the  whole  continent  of  America,  and 
several  of  its  species  occur  on  the  highest  elevations  of  the  Rocky  Moun 
tains.  Several  species  are  common  to  Europe  and  America;  and  it  is  to 
one  of  these  that  (E.  scmidca  is  most  closely  allied.  A  few  species 
descend  into  the  Hudsonian  fauna;  but,  as  a  whole,  the  genus  has  its

metropolis  farther  north.  So  that  in  ascending  Mt.  Washington,  we  pass, 
as  it  were,  from  New  Hampshire  to  northern  Labrador;  on  leaving  the 
forests,  we  come  first  upon  animals  recalling  those  of  the  northern  shores 
of  the  Gulf  of  St.  Lawrence  and  the  coast  of  Labrador  opposite  New 
foundland  ;  and  when  we  have  attained  the  summit,  we  find  insects  which 
represent  the  fauna  of  Atlantic  Labrador  and  the  southern  extremity  of 
Greenland.* 

We  have  hitherto  spoken  only  of  the  barren  elevations ;  below  these 
we  find  the  mountain  or  wooded  region  corresponding  altogether  with 
the  Canadian  fauna.  The  boundary  line  between  this  and  the  Allegha- 
nian  fauna  crosses  the  country  at  about  this  latitude,  and  therefore  this 
region  forms  a  promontory  of  the  Canadian  fauna  stretching  southwardly 
into  the  Alleghanian  fauna,  just  as  occurs  to  a  greater  extent  along  the 
chain  of  the  Green  Mountains,  while  the  Alleghanian  fauna,  in  its  turn, 
extends  northward  into  the  Canadian  fauna,  along  the  warmer  banks  of 
those  rivers  which  find  a  southern  outlet.  We  need  only  wander  eight 
miles  north  of  Mt.  Washington  itself  to  find,  in  the  valley  of  the  Andro- 
scoggin,  the  entomological  fauna  of  the  central  portions  of  the  New 
England  states,  while  between  the  two,  in  the  mountain  region  and  in 
that  portion  of  the  Canadian  fauna  lying  in  the  valley  of  the  Peabody, 
we  have  such  phenomena  as  the  replacement  of  Polygonia  comma  of  the 
Alleghanian  fauna  by  P.  Faunus  of  the  Canadian,  and  of  Argynnis 
Aphrodite  by  A,  Atlantis. 

We  have,  then,  three  distinct  faunas  upon  the  slopes  of  the  White 
Mountains,!  each  with  its  characteristic  forms.  However  much  we  may 
expect  some  difference  between  the  animals  of  the  barren  summits  and 
those  of  the  sheltered  valleys,  we  are  struck  at  finding  such  distinct 
regions,  each  sheltering  its  own  peculiar  forms,  which  live,  as  it  were, 
"within  a  stone's  throw  of  each  other,  and  would  seem  to  be  capable  of 

*  Dr.  A.  S.  Packard,  writing  of  the  region  about  Hopedale,  Labrador,  says  that  he  found  the  species  of 
OZneis  in  great  abundance  on  the  outer  barren  exposed  islands,  while  those  of  Brenthis  were  confined  to  the 
valleys  of  the  main  land  or  the  southerly  slopes  of  the  more  protected  islands,  near  the  low  stunted  spruces  and 
the  more  luxuriant  vegetation  of  that  desolate  coast. 

t  It  must  not  be  supposed  that  all  the  insects  which  characterize  the  faunas  of  the  barren  regions  have 
been  mentioned.  I  have  only  chosen  a  few  from  many  which  might  be  given.  Nearly  every  year  fresh  instances 
are  recorded  and  partial  lists  have  been  made.  It  is  unfortunate,  however,  that  we  seldom  find  any  specification 
of  the  exact  locality  or  height  at  which  an  insect  has  been  taken,  or  of  its  comparative  abundance;  so  that  the 
notes  at  hand  are  worthless  for  any  purposes  of  distinction  between  an  alpine  and  a  sub-alpine  fauna ;  they  serve 
only  to  show  how  strikingly  the  general  fauna  agrees  with  that  of  the  -whole  of  Labrador.

interchanging  their  stations,  and  yet  which  never  pass  their  impercepti 
ble  barriers.  Many  butterflies  from  the  valley  occasionally  struggle  to 
the  extremest  summits,  and  one  or  two,  such  as  Polygonia  Faunns  and 
Aglais  Milberti,  are  frequently  found  within  the  sub-alpine  region.  In 
all,  the  capabilities  of  flight  are  unlimited,  yet  I  have  but  two  or  three 
times  taken  (Eneis  scmidea  more  than  a  mile  and  a  quarter  from  the 
summit ;  and  the  appearance  of  the  valley  butterflies  upon  the  heights 
may  easily  be  accounted  for,  from  the  fact  that  all  insects  with  reasonable 
powers  of  flight  seem  to  delight  in  seeking  the  most  elevated  situations. 
Their  scanty  numbers  in  these  parts  is  in  marked  contrast  with  their  often 
astonishing  profusion  in  their  proper  haunts  below. 

The  results  we  have  reached,  by  our  study  of  the  faunas  of  these 
mountain  slopes,  are  what  might  be  expected  from  a  comparison  of  the 
elevation  of  these  mountains  with  that  of  the  European  Alps,  at  the  same 
time  taking  into  consideration  the  difference  in  climate  between  the  two 
countries.  In  the  Alps  the  lower  limit  of  the  sub-alpine  zone  is  placed 
by  different  writers  at  from  4000  to  4500  feet  above  the  sea,  and  that  of 
the  alpine  zone  at  from  6000  to  6500  feet.  Now,  although  Mt.  Blanc  lies 
in  a  latitude  (45°  45')  north  of  Mt.  Washington  (44°  15')  by  a  degree  and 
a  half,  yet  a  comparison  of  the  isothermal  and  isochimenal  lines,  which 
pass  respectively  through  these  two  points,  would  show  that  a  mountain 
elevation  in  Europe,  which  should  have  climatic  conditions  similar  to 
those  of  the  White  Mountains,  ought  to  be  placed  north  of  the  Alps,  and 
would  be  found  between  the  mountains  of  Switzerland  and  Norway  at 
just  such  a  proportionate  distance  from  them  as  the  heights  of  the  alpine 
and  sub-alpine  zones  of  the  White  Mountains  were  found  to  be  related 
respectively  to  those  of  the  Alps  and  Scandinavian  mountains.  By  the 
same  comparison  we  may  also  judge,  that  if  the  summit  of  Mt.  Wash 
ington  were  somewhat  less  than  two  thousand  feet  higher,  it  would 
reach  the  upper  limits  of  the  alpine  district,  or  the  region  of  perpetual 
snow. 

An  attempt  to  institute  a  rigid  comparison  between  the  alpine  and 
sub-alpine  regions  of  our  White  Mountains  and  those  of  the  Alps  is  not 
so  easy  as  would  be  imagined.  If  we  examine  their  physical  features 
alone,  we  shall  discover  important  differences.  In  New  Hampshire  these 
regions  are  confined  solely  to  the  summits  of  the  very  highest  moun- 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  343 

tains,  all  comprised  within  a  few  square  miles,  exposed  almost  continu 
ously  to  the  very  fiercest  gales ;  they  are  covered  by  interminable  broken 
rock-masses,  concealed  in  part  by  a  scanty  layer  of  mould,  supporting 
either  sedges,  or  stunted  juniper-like  spruces,  whose  gnarled  and  spreading 
branches  creep  along  the  ground.  In  Switzerland  and  the  Tyrol  these 
regions  extend  over  an  area  of  thousands  of  square  miles,  more  or  less 
continuous ;  the  highest  mountains  rise  above  them  into  the  region  of 
perpetual  snow,  and  form  barriers  to  the  wind,  rendering  the  alpine  slopes 
scarcely  more  breezy  than  the  plains.  About  the  Belalp,  above  Brieg, 
where  I  have  paid  most  attention  to  the  insects  of  the  high  Alps,  the 
trees  seem  to  reach  a  general  level  of  about  6000  feet  ;*  above  them  the 
ground  is  sward,  richly  beautified  by  flowers,  and  a  pasturing  ground 
for  goats  and  cattle ;  on  the  slopes  most  exposed  to  the  morning  and 
midday  sun,  immense  patches  of  low,  dark  green  shrubbery,  seldom 
rising  more  than  a  foot  above  the  ground,  dispute  the  soil  with  the  grass. 
These  patches  consist  mainly  of  heather  (Calluna)  with  Rhododendron  and 
several  species  of  Vaccinium,  and  seem  to  represent  the  dwarfed  spruces 
of  our  alpine  heights,  which,  near  the  forests,  are  also  accompanied  by 
Vaccinium.  The  sward  extends  up  to  the  snow  and  cliffs,  and  while 
sedges  are  no  doubt  present,  its  mass  is  composed  of  Gramineae. 
During  the  few  days  early  in  July  spent  in  this  region,  I  noticed  that 
insects,  especially  butterflies,  were  most  numerous  between  5500  and 
8000  feet  above  the  sea.  The  most  abundant  species  of  the  very  highest 
region  were  Pieris  Callidice  and  Erebia  Manto ;  and  many  caterpillars  of 
Melitcea  Cynthia  were  found,  crawling  about  the  rocks.  Between  6500 
and  7500  feet,  the  more  common  species  were  Syrichtus  malvce,  CEneis 
Acllo  (not  rare),  Brenthis  Pales  (common),  two  or  three  species  of 
Erebia,  including  E.  Manto,  Colias  Palceno  (common),  and  Pieris  Calli- 
•  dice  (common);  Vanessa  Atalanta  and  Aglais  urticce  were  also  seen,  the 
latter  frequently ;  the  species  of  CEneis  and  Brenthis  seemed  to  occupy 
an  identical  zone.  Lower  down,  the  Blues  appeared  in  abundance,  with 
different  species  of  Erebia ;  Parnassius  Apollo  occurred  in  considerable 
numbers,  Syrichtus  malvcz  was  extremely  abundant,  Aglais  urticce  was 
very  common,  and  eggs  and  young  caterpillars  could  be  found  anywhere ;

even  (Ends  Acllo  was  not  infrequent,  but  Picris  Callidice  was  not 
seen. 

CEneis  Aello  was  very  wary,  and  possessed  of  a  very  vigorous,  energetic 
flight ;  CE.  semidea,  on  the  other  hand,  has  a  very  weak  flight,  and  suffers 
itself  to  be  blown  about  at  random  by  the  wind.  This  difference  seems 
all  the  more  striking  when  we  remember  that  CE.  semidea  inhabits  a 
region  of  tempestuous  winds,  where  existence  would  seem  impossible  to 
a  butterfly,  unless  unusually  gifted.  Both  species,  when  at  rest,  sit  with 
wings  back  to  back,  the  front  pair  concealed  as  much  as  possible  between 
the  hind  pair;  but  CE.  Aello  always  sits  erect,  or  only  slightly  inclined, 
while  CE.  semidea  is  rarely  erect,  and  often,  when  it  has  alighted  upon  the 
horizontal  surface  of  a  rock  or  by  the  muddy  brim  of  a  pool,  fairly  lies 
upon  its  side,  as  if  dead. 

In  the  following  pages  we  give  a  list  of  the  butterflies  and  Orthoptera 
of  New  Hampshire,  as  far  as  they  are  known.  The  list  of  Orthoptera  is 
given  almost  entirely  from  memoranda  collected  by  myself.  For  notes 
on  the  butterflies,  I  am  indebted  to  many  persons,  but  especially  to  Mr. 
C.  P.  Whitney,  of  Milford,  N.  H.  In  this  list  I  have  incorporated  as  full 
an  account  as  possible  of  the  two  butterflies  peculiar  to  the  barren  sum 
mits  of  the  White  Mountains.

As  stated  in  the  first  part  of  this  memoir,  this  insect  probably  occupies 
a  more  restricted  geographical  area  than  any  other  butterfly  in  the  world, 
the  narrow  area  of  the  alpine  fauna  of  the  White  Mountains.  Dr.  Har 
ris's  assertion  that  "it  has  also  been  seen  on  the  Monadnock  mountain, 
and  will  probably  be  discovered  on  the  tops  of  the  high  mountains  in  our 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  345 

own  state"  (Massachusetts),  is  wholly  erroneous.  I  have  ascended  Grey- 
lock,  the  highest  mountain  in  Massachusetts,  more  than  twenty  times, 
and  at  all  seasons  of  the  year,  and  certainly  could  not  have  failed  to  see 
this  butterfly  did  it  occur  there.  Since  Monadnock  is  a  naked  peak,  it 
would  certainly  be  a  more  propable  habitat  for  the  insect ;  but  the  limita 
tion  of  its  distribution  in  the  White  Mountains  wholly  forbids  the  possi 
bility  of  its  presence  on  a  much  lower  and  isolated  mountain  to  the 
south. 

The  butterfly  is  found  most  abundantly  from  about  one  quarter  to  three 
quarters  of  a  mile  from  the  summit  of  Mt.  Washington,  or  at  an  elevation 
of  from  5600  to  6200  feet  above  the  sea.  It  often  alights  on  the  flowers 
of  Silcne  acaulis  Linn.,  and  also  upon  some  of  the  Ericaceae,  particularly 
on  a  species  of  Vaccinium ;  but  the  best  collecting  places  are  the  sedgy 
plateaus  of  the  north-eastern  and  southern  sides  of  the  mountain,  where 
the  collector  will  also  obtain  a  good  footing,  a  matter  of  no  small 
importance  on  such  a  collecting  ground.  I  have  never  found  the  butterfly 
at  the  head  of  any  of  the  deep  ravines. 

Dr.  Meyer-Diir  states  of  GE,  Aello,  the  species  occurring  in  the  Euro 
pean  Alps,  that  it  inhabits  the  calcareous  and  central  mountains, — not  the 
highest  chains,  as  has  been  generally  supposed,  but  rather  the  middle 
regions,  from  4000  to  6000  feet  above  the  sea.*  He  also  makes  the 
remarkable  assertion  that  the  butterfly  appears,  at  least  in  Switzerland,! 
only  on  alternate  years,  namely,  those  with  even  numbers.  Prof.  Frey 
thinks  this  to  be  true  only  for  each  special  locality,  but  that  every 
year  it  may  be  found  in  some  of  them. 

All  the  species  of  this  family  of  butterflies,  so  far  as  they  are  known, 
feed  in  the  caterpillar  state  on  grasses ;  \  but  as  the  true  grasses  are  rare 
in  the  inhospitable  region  where  this  insect  is  found,  being  replaced  almost 
altogether  by  sedges,  the  caterpillar  feeds  upon  the  latter.  Mr.  Sanborn 
has  seen  them  eating  it  by  day,  and,  by  the  aid  of  a  lantern,  I  discovered 

*  See  our  previous  remarks  on  this  species,  p.  343. 

f  Meyer-Dur  says  further,  that  the  records  of  its  capture  out  of  Switzerland  are  also  in  even  years ;  but,  since 
writing  the  above,  I  notice  that  Speyer,  in  his  work  on  the  geographical  distribution  of  the  Lepidoptera  of  Ger 
many  and  Switzerland  (II,  271),  says  that,  according  to  Trapp,  it  appears  every  year,  but  in  some  years  more 
abundantly  than  in  others. 

J  This  is  not  strictly  true,  as  I  thought  when  writing  it.     Boisduval,  Rambur,  and  Graslin,  in  their  work  on  the 
caterpillars  of  Europe,  state  that  Ccenonympha  Corinna  feeds  both  on  Triticum  and  Carex;  and  Wilde,  accord 
ing  to  Kaltenbach  (Pflanzenfeinde,  728),  gives  Lolium  and  Carex  as  the  food  of  Pararge  Ac/tint".

them  feeding  on  the  same  plant,  Carex  rigida,  by  night.  This  shows 
that  I  was  mistaken  in  a  belief  formerly  expressed,  that  they  fed  upon 
lichens. 

CEneis  semidea  was  first  discovered  about  half  a  century  ago,  and 
described  by  Say  from  specimens  sent  him  by  Dr.  Pickering  and  Prof. 
Nuttall,  of  Boston.  Very  few  specimens  seem  to  have  been  taken  since 
that  time,  until  1859,  when  I  made  my  first  considerable  collections  in  the 
White  Mountains.  I  ascended  the  highest  peak  on  July  8,  for  the  express 
purpose  of  finding  the  butterfly,  and  secured  my  first  specimen  at  about 
a  mile  from  the  summit,  near  the  foot-path  from  the  Glen.  On  ascending, 
the  butterfly  became  more  abundant ;  and,  although  our  party  hastened 
over  the  ground,  more  than  forty  good  specimens  were  taken,  and  a  friend 
even  captured  seven  without  a  net.  Less  than  a  week  afterwards,  in  a 
little  more  than  an  hour's  collecting,  fifty-nine  were  taken,  for,  in  its 
season,  this  butterfly  is  exceedingly  abundant. 

Dr.  Harris  gives  "June  and  July"  as  the  season  of  the  flight  of  the 
imago,  the  former  date  on  the  authority  of  Oakes,  who  found  the  insect 
abundant  in  June,  1826.  Undoubtedly  this  was  toward  the  close  of  the 
month.  It  usually  begins  to  appear  very  early  (the  first  week)  in  July,  be 
comes  exceedingly  abundant  before  the  middle  of  the  month,  and  continues 
until  about  the  second  week  in  August.  Mr.  Sanborn  gives  July  4th  as 
its  earliest  appearance  in  1869,  and  only  one  more  specimen  was  seen 
before  the  9th,  although  the  weather  was  favorable.  This  may  serve,  I 
think,  as  an  average  date,  and  the  butterflies  will  best  be  taken  in  the 
second  and  third  weeks  in  July.  They  lay  their  eggs  until  about  the  22d 
of  July,  and  probably  a  little  later.  These  are  apparently  dropped  loosely 
among  the  sedges,  for  I  could  obtain  no  eggs  on  the  sedge  itself  from 
gravid  females  confined  in  open  kegs,  and  finally,  searching  among  the 
roots  as  a  last  resort,  I  discovered  a  single  egg,  which,  however,  never 
hatched.  Caterpillars  have  been  found  by  Mr.  Sanborn,  the  late  Mr. 
Shurtleff,  and  myself,  nearly  full  grown,  on  the  2d  of  August,  and  others 
certainly  full  grown  on  August  19.  More  recently  Mr.  Whitney  has 
found  them  "  apparently  fully  grown,  under  stones."  They  were  unques 
tionably  seeking  a  good  place  to  undergo  their  transformations.  They 
probably  transform  to  chrysalids  at  once,  and  hibernate  in  that  state, 
although  it  is  possible  that  they  winter  as  Mr.  Whitney  found  them.  In

the  early  part  of  July,  1869,  Mr.  Sanborn  searched  very  carefully  for  the 
chrysalids  of  this  species,  spending  ten  or  twelve  hours  in  raising  mova 
ble  surface  stones,  and  in  four  or  five  places  clearing  away  to  the  depth 
of  several  feet  the  smaller  blocks  of  stone  lying  in  the  "  rock  rivulets," 
as  he  appropriately  terms  the  slight  gulleys  wholly  devoid  of  vegetation, 
which  are  scattered  everywhere  over  the  plateaus,  and  which  mark  the 
course  of  the  surface  waters  after  rain.  He  succeeded  in  securing  only 
two  living  specimens.  Nine  others  were  either  infested  by  ichneumons 
(Eulophus  semidea  Pack.,  and  Encyrtus  Montinus  Pack.,  described 
below*),  or  were  the  empty  shells  of  the  previous  year.  They  were  all 
found  imbedded  between  the  sides  of  the  rock  and  the  long,  dense,  crisp 
moss  surrounding  it,  between  half  an  inch  and  an  inch  and  a  half  below

the  general  surface,  where  the  caterpillars  had  entered.  They  were  not 
attached  to  the  rock  or  the  moss,  but  lay  in  horizontal  oval  cells,  evidently 
formed  by  the  movements  of  the  caterpillar  before  pupation.  The  most 
particular  examination  revealed  no  trace  of  any  web  or  silken  thread, 
even  as  a  lining  of  the  cell.  Mr.  Sanborn's  impressions,  drawn  mainly 
from  a  comparison  between  the  slender  number  of  specimens  he  obtained 
and  the  abundance  of  the  butterfly,  are,  that  the  healthier  caterpillars 
penetrate  even  deeper  into  the  ground  ;  but  as  I  have  also  found  them 
under  or  beside  surface  stones,  and  Mr.  Whitney  has  discovered,  larvae 
ready  for  their  change  in  similar  localities,  I  am  more  disposed  to  believe 
that  the  place  to  seek  them  is  beneath  and  beside  the  uppermost  stones, 
and  especially  at  the  edges  of  the  "rock  rivulets,"  where  the  vegetation 
is  usually  the  freshest.  To  one  familiar  with  the  locality, — a  surface 
almost  completely  strewn  with  angular  rock  fragments, — Mr.  Sanborn's 
exploration  will  seem  to  have  been  a  very  successful  one.  Most  of  his 
specimens  were  found  at  more  than  a  mile  from  the  summit ;  doubtless 
better  success  would  attend  efforts  in  localities  not  more  than  half  or 
three  quarters  of  a  mile  from  the  top. 

One  would  suppose  that  insects,  whose  home  is  almost  always  swept  by 
the  fiercest  blasts,  would  be  provided  with  powerful  wings  fitting  them 
for  strong  and  sustained  flight ;  but  the  contrary  is  true.  They  can  offer 
no  resistance  to  the  winds,  and  whenever  they  ascend  more  than  their 
accustomed  two  or  three  feet  above  the  surface  of  the  ground,  or  pass 
the  shelter  of  some  projecting  ledge  of  rocks,  they  are  whirled  headlong 
to  immense  distances,  until  they  can  again  hug  the  earth.  Their  flight  is 
sluggish  and  heavy,  and  has  less  of  the  dancing  movement  than  one  is 
accustomed  to  see  in  the  Oreades.*  They  are  easily  captured. 

The  European  Aello  appears,  says  Meyer-Dur,  among  the  earliest  but 
terflies  of  the  Alps.  It  is  seen  soon  after  the  snow  melts, — first,  on  the 
lower  grounds  at  the  end  of  May ;  last,  on  the  higher  levels  (correspond 
ing  more  nearly  to  those  to  which  our  species  is  restricted)  at  about  the 
beginning  of  July ;  it  disappears  in  the  same  way  from  the  end  of  June 
to  the  end  of  the  first  week  in  August. 

2.  Enodia  Portlandia  Scudd.  Within  the  limits  of  New  England  this 
is  a  very  rare  insect.  It  may  be  found  occasionally  upon  the  banks  of 

*  See  p.  346. 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  349 

the  southern  Connecticut,  since  Mr.  Emery  reports  that  it  is  "not  uncom 
mon"  in  certain  stations  about  Holyoke  and  Mt.  Tom  in  Massachusetts. 
I  have  also  taken  two  battered  specimens  at  Jefferson,  in  the  White 
Mountains.  Gosse  took  it  at  Compton,  Lower  Canada,  and  D'Urban  on 
the  River  Rouge,  north  of  the  Ottawa;  three  or  four  specimens  have 
also  been  captured  at  Suncook,  N.  H.  (Thaxter). 

3.  Minois  A  lope  Scudd.     This  insect  is  tolerably  abundant,  sometimes 
very  common,  in  the  southern  half  of  New  England,  occurring  through 
out  Massachusetts    and    the  two   states  lying  south  of  it,  and  in  the 
southern  extremities  of    Maine,  New  Hampshire,  and  Vermont.     The 
most  northern  localities  from  which  I  have  seen  specimens,  or  received 
notes  of  its  capture,  are  Norway,  Me.  (Smith),  Thornton  and  Shelburne, 
N.  H.  (Faxon),  and  Sudbury,  Vt.     Mr.  Jones  states  that  it  is  also  found 
in  Nova  Scotia.     It  occurs  in  open  woods  and  orchards,  as  well  as  along 
roadsides  and  stone  walls,  especially  such  as  are  overgrown  with  brambles 
or  skirted  by  shrubbery. 

4.  Minois  NepJiele  Scudd.     This  insect  is  found  over  the  whole  northern 
half  of  New  England  in  great  abundance.     The  only  locality  in  which  I 
have  met  with  it  in  Massachusetts  is  the  elevated  region  about  Williams- 
town,  but  it  undoubtedly  approaches  closely  to  the  northern  limits  of  the 
state. 

5.  Argus  Eurydice  Scudd.     In  New  England  this  is  not  a  very  rare 
insect,  especially  in  the  northern  and  elevated  parts.     There  is  no  notice 
of  its  capture  south  of  Massachusetts,  nor  in  the  Connecticut  valley 
south  of  New  Hampshire.     In  the  latitude  of  the  White  Mountains,  and 
as  far  south  as  Campton,  it  will  be  found  extremely  abundant  by  those 
who  look  for  it  in  its  proper  haunts,  elevated  moist  meadows. 

6.  Megisto  Eurytus  Scudd.     The  northern  limit  of  this  butterfly  prob 
ably  follows  the  isotherm  of  45°,  for  this  seems  to  be  its  boundary  in  New 
England,  since  it  is  found  in  some  abundance  in  Walpole  (Smith)  and 
Milford,  N.  H.  (Whitney).     There  is  no  record  of  it  farther  north,  except 
ing  at  Norway,  Me.,  where  Mr.  Smith  found  it  in  abundance ;  at  Plymouth, 
where  it  is  not  very  common  (Scudder);  and  at  Brunswick,  Me.  (Packard), 
toward  which  place,  being  on  the  sea-coast,  the  isotherm  probably  turns. 
It  does  not  occur  among  the  White  Mountains,  but  probably  will  be  found 
close  to  their  southern  boundaries,  and  quite  as  far  north  in  Vermont. 


35O  PHYSICAL    GEOGRAPHY. 

7.  Danaiis  Plexippus  Latr.     This  butterfly  ranges  over  the  whole  North 
American  continent  from  Atlantic  to  Pacific  (excluding  perhaps  the  Rocky 
Mountain  district),  as  far  north  as  the  annual  isotherm  of  40°,  and  over 
that  portion  of  South  America  lying  east  of  the  Andes  and  north  of  Rio 
de  Janeiro,  including,  also,  many  and   perhaps    all  of   the  West  India 
islands.     It  occurs  throughout  New  England,  but  it  is  much  more  rare  in 
the  northern  than  in  the  southern  part,  though  even  here  it  can  hardly 
be  called  abundant,  for,  usually,  specimens  must  be  captured  singly.    Yet, 
now  and  again,  it  swarms,  as  in  the  autumn  of  1871.     In  some  localities 
it  is  especially  numerous, — such  places,  for  instance,  as  islands  off  the 
coast,  or  broad  sandy  sea-beaches,  where  no  Asclepias  grows.     Is  it  that 
an  innate  propensity  for  geographical  extension  leads  it  to  the  last  possi 
ble  limit  ?     Mr.  L.  L.  Thaxter  states  that  it  is  found  in  great  numbers  on 
Appledore,  the  largest  of  the  Isles  of  Shoals,  which  has  a  surface  of  about 
500  acres ;  yet  there  is  no  trace  of  milk- weed  upon  any  of  these  islands, 
which  he  has  thoroughly  explored.     It  has  not  been  recorded  from  the 
White  Mountains. 

8.  Basilarchia  Disippe  Scudd.     Within  New  England,  Disippe  occurs 
abundantly  in  the  south,  sparingly  in  the  north,  although  found  in  the 
very  heart  of  the  White  Mountains.     Gosse  does  not  record   it  from 
Compton,  Canada;  and  the  northernmost  points  from  which  specimens 
have  been  reported  are  Mt.  Desert  (Scudder),  Waterville  (Hamlin),  and 
Norway,   Me.  (Smith),  the  Glen,  White  Mountains,  and   Sudbury,  Vt. 
(Scudder). 

9.  Basilarchia  Astyanax  Scudd.     The  general  range  of  this  butterfly 
is  similar  to  that  of  the  preceding,  though  less  extensive.     It  is  tolerably 
abundant  in  the  southern  parts  of  New  England,  and  occurs  about  as  far 
north  as  the  annual  isotherm  of  45°,  the  northernmost  points  recorded 
being  Dublin  (Faxon)  and  Milford,  common  (Whitney). 

10.  Basilarchia  Arthemis  Scudd.    This  species  of  Basilarchia  has  a  very 
different  range  from  the  two  preceding,  its   southern  limits  nearly  co 
inciding  with  the  northern  boundaries  of  B.  astyanax.     In  New  England 
it  has  not  been  taken  south  of  Massachusetts,  and  but  rarely  in  that  state. 
It  is  already  common  at  Brattleborough,  Vt.,  Walpole  (Smith),  Weare 
(Emery),  and  Dublin,  N.  H.  (Faxon  and  Leonard) ;  but  it  is  said  to  be 
scarce  in   Milford  (Whitney),  and   in   the  immediate   neighborhood  of 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  35! 

Dublin.  In  the  White  Mountain  region,  and  in  northern  New  England 
generally,  it  is  exceedingly  abundant,  far  more  so  than  the  other  species 
of  the  genus  in  their  most  favorable  localities.  Indeed,  the  matrons  of 
farm-houses,  in  the  valley  of  Peabody  river,  complain  of  the  insects 
entering  the  kitchens  in  such  numbers  as  to  be  a  very  nuisance.  One  of 
them,  Mrs.  Dolly  Copp,  of  "Imp  cottage"  (well  known  to  many  frequenters 
of  "the  Glen"),  relates  how  she  has  taken  more  than  fifty  on  the  inside 
of  her  windows  in  a  single  morning. 

11.  Polygonia  intcrrogationis  Scudd.     In  New  England  this  butterfly 
is  nowhere  very  abundant,  and  in  the  northern  portions  very  rare.     The 
northernmost  localities  from  which  it  is  reported  are  Brunswick  (Packard) 
and  Norway,  Me.  (Smith),  and  Walpole  (Smith)  and  Milford,  N.  H.,  one 
specimen  only  (Whitney). 

12.  Polygonia  comma  Scudd.  is  found  throughout  New  England,  except 
ing  in  the  White  Mountain  region,  and  perhaps  other  elevated  portions  of 
the  northern  counties.     It  has,  however,  been  taken  on  Camel's  Hump, 
Vt.  (Sprague),  and  given  as  a  probable  inhabitant  of  Norway,  Me.  (Smith). 

13.  Polygonia  Faunus  Scudd.     This  butterfly  is   as  peculiar  to  the 
Canadian  fauna  as  P.  comma  is  to  the  Alleghanian.     In  New  England  it 
is  found  only  in  the  north,  the  southernmost  localities  from  which  it  has 
been  recorded  being  Williamstown,  Mass.  (Scudder),  Dover  and  Camel's 
Hump,  Vt.  (Sprague),  Dublin  (Faxon)  and  Milford,  N.  H.,  two  specimens 
(Whitney),  and  Norway,  Me.  (Smith).     In  the  valleys  of  the  White  Moun 
tains  it  is  exceedingly  abundant,  and  is  the  butterfly  oftenest  seen  in  deep 
ravines  and  on  mountain  slopes  below  the  sub-alpine  region.     More  than 
any  other  species  belonging  to  the  mountain  region,  it  mounts  to  the  very 
summit  of  the  highest  peaks,  far  above  any  plant  upon  which  its  larva 
would  be  likely  to  feed.     Edwards  reports  a  single  specimen  from  West 
Virginia,  and  Abbott  records  it  from  the  mountains  of  Georgia!     I  con 
sider  P.  gracilis  a  dimorphic  form  of  this  species. 

14.  Polygonia  Progne  Hiibn.  [Plate  A.,  Fig.  12.]     The  range  of  this 
butterfly  corresponds  very  closely  with  that  of  P.  comma.     In  New  Eng 
land  it  is  more  generally  distributed  and  universally  common  than  any 
other  species  of  Polygonia.     It  is  somewhat  more  abundant  in  the  south 
ern  than  in  the  northern  parts.     I  have  this  spring  taken  a  single  specimen 
in   the  White   Mountain  region.     It   is   common   in   some  seasons  at 


352  PHYSICAL    GEOGRAPHY. 

Norway,  Me.  (Smith),  and  has  been  found  at  Thornton  and  Shelburne,  N. 
H.  (Faxon).  It  will  probably  prove  to  be  rare  in  the  elevated  regions  of 
northern  New  Hampshire  and  Maine. 

15.  Nymphalis  J.  album   Scudd.   occurs  throughout   New  England, 
although  very  rare  in  the  northernmost  portions.     In  the  White  Moun 
tain  district  and  its  vicinity  it  is  abundant,  as  it  doubtless  is  through  all 
that  portion  of  New  England  lying  north  of  the  isotherm  of  40°,  for  the 
spring  months.     Mr.  Roland  Thaxter  mentions  it  as  exceedingly  common 
at  Suncook,  but  it  is  much  less  so  at  Milford  (Whitney). 

1 6.  Papilio  Antiopa  Linn.     This  butterfly  is   apparently  distributed 
over  the  entire  breadth  of  the  Northern  Hemisphere  below  the  arctic 
circle,  as  far  as  the  thirtieth  parallel  of  latitude  in  America,  and  the 
fortieth  in  the  old  world.     It  is  found  in  nearly  equal  abundance  through 
all  parts  of  New  England,  so  numerous,  indeed,  as  to  become  positively 
injurious  on  account  of  the  damage  done  by  the  caterpillar  to  some  of  our 
choicest  ornamental  trees. 

17.  Aglais  Milbcrti  Scudd.     This    insect  is  found   throughout  New 
England,  but  is  extremely  rare  in  the  southern  portions.     Probably  the 
isotherm  of  23°  for  the  winter  months  would  mark  the  limit  of  its  abun 
dance.     It  is  rather  common  in  Walpole,  Dublin,  Milford,  and  the  Isles  of 
Shoals.     Still  farther  north  it  is  very  abundant,  often  the  commonest 
species  in  its  season,  and  is  plentiful  even  in  the  White  Mountain  region 
itself. 

1 8.  Vanessa  Atalanta  Fabr.     This  butterfly  enjoys  a  very  extensive 
geographical  range,  extending  over  nearly  the  whole  of  the  North  Amer 
ican  and  European  continents.     I  believe  it  is  found  plentifully,  and  in 
nearly  equal  numbers,  through  every  part  of  New  England,  although  there 
is  no  record  of  its  capture  in  the  heart  of  the  White  Mountain  region. 
As  the  abundance  of  this  species  is  more  than  ordinarily  affected  by  the 
action  of  parasites,  the  records  of  a  single  year  for  any  locality  are  com 
paratively  valueless. 

19.  Vanessa  Huntcra  Hiibn.     It  is  far  more  common  in  the  southern 
than  in  the  northern  portions  of  New  England,  and  is  wholly  wanting  in 
the  White  Mountain  district,  although  occurring  as  far  north  as  Quebec. 
The  northernmost  localities  from  which  it  has  been  reported  are  Water- 
ville,  very  few  (Hamlin),  and  Norway,  Me.  (Smith),  and  Milford,  N.  H., 
scarce  (Whitney). 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  353 

20.  Vanessa  cardui  Ochs.     This  insect,  says  Speyer,*  "is   the   most 
widely  distributed  of  all  butterflies,  and  perhaps  of  all  Lepidoptera.     It 
inhabits  the  whole  of  Europe  as  far  north  as  Lapland,  the  whole  of  Asia 
(with  perhaps  the  exception  of  the  polar  regions),  the  whole  of  Africa, 
America  from  Hudson's  bay  to  Brazil,  and  Australia ;  that  is  to  say,  all 
parts  of  the  world,  every  zone,  the   northern  as  well  as    the   southern 
hemisphere,  its  area  of  dispersion  embracing  little  less  than  the  whole 
globe.     Moreover,  in  the  warm  regions  it  is  by  no  means  restricted  to 
the  higher  altitudes,  but  inhabits  the  plains  under  the  equator  as  well  as 
in  Lapland.     It  has  therefore  nowhere  on  the  earth  an  inferior  limit  to 
its  distribution,  through  excess  of  temperature  or  insufficiency  of  mois 
ture.     As  to  its  upper  limits,  it  is  restricted  only  by  the  eternal  snows  of 
the  loftiest  mountains.     It  is,  however,  not  yet  determined  whether  it  is 
found  in  the  treeless  regions  of  the  arctic  zone,  as  it  is  in  the  sub-glacial 
districts  of  the  Alps."     There  is  no  spot  in  New  England  where  it  may 
not  be  found  at  certain  seasons  in  abundance. 

21.  Junonia  Cccnia  Hiibn.     In  New  England  this  is  an  exceedingly 
rare  insect.     Mr.  Smith  has  seen  several  specimens  from  the  vicinity  of 
New  Haven ;  Mr.  McCurdy  found  it  somewhat  plentiful  one  autumn  in 
the  vicinity  of    Norwich,  Conn. ;  Col.   Higginson  reports  several  from 
Newport,  R.  I.;  and  Mr.  Bennett  captured  a  single  specimen  at  Springfield. 
Mr.  Sanborn  and  myself  have  both  taken  specimens  on  Cape  Cod.     Dr. 
Harris  took  one  specimen  at  Milton,  Mass.;  and  I  have  captured  a  single 
individual  at  Hampton,  N.  H.,  the  northernmost  locality  from  which  it  has 
been  reported  in  New  England,  or,  indeed,  in  America. 

22.  Speycria  Idalia  Scudd.     Generally  speaking  this  is  not  a  common 
insect  in  New  England,  and  is  seldom  seen  above  the  annual  isotherm  of 
45°.     The  most  northerly  stations  from  which  it  is  recorded  are  Bruns 
wick,  Me.  (Packard),  Isles  of  Shoals,  a  few  specimens,  and  Suncook,  not 
common   (Thaxter),   Milford,  common  (Whitney),  Dublin   (Faxon),  and 
Walpole,  N.  H.  (Smith). 

23.  Argynnis  Cybelc  God.     In  New  England  this  insect  is  scarcely 
larger  than  A.  Aphrodite,  and  the  two  species  have  frequently  been  con 
founded,  but  it  is  found  throughout  the  whole  area,  excepting  the  White

Mountain  region,  and  probably  most  of  the  country  farther  north.  In  the 
northern  half  of  the  district  it  is  uncommon,  but  in  the  extreme  south 
exceedingly  abundant.  The  most  northern  known  localities  are  Bruns 
wick,  Waterville,  and  Norway,  Me.;  and  in  New  Hampshire,  Isles  of 
Shoals  (not  common),  Suncook  (not  common),  Milford  (very  abundant), 
Walpole,  and  Plymouth. 

24.  Argynnis  Aphrodite  God.      In  New  England  this  is  one  of  our 
commonest  butterflies,  but  it  is  wholly  absent  from  the  White  Mountain 
region,  where  it  is  replaced  by  the  next  species. 

25.  Argynnis  Atlantis  Edw.     Abundant  through  all  the  cooler  parts  of 
Canada,  and  very  closely  limited  southwardly  by  the  annual  isotherm  of 
45°,  only  surpassing  it  in  elevated  regions  and  along  mountain  chains. 
In  New  England  it  is  probably  common  everywhere  north  of  the  isotherm 
of  45°  maximum  temperature  for  the  spring  months,  but  is  really  abun 
dant  only  in  the  White  Mountain  district,  where  it  wholly  replaces  A. 
Aphrodite.     Other  New  Hampshire  localities  are  Thornton,  Shelburne 
(Faxon,  Minot),  Littleton  (Sanborn),  Jefferson  (Scudder),  and  even  Sun- 
cook  (Thaxter),  Dublin  (Faxon),  and  Milford,  very  rare  (Whitney). 

26.  BrentJiis  Myrina  Herr.-Schaff.     This  butterfly  is  found  in  nearly 
equal  abundance  throughout  New  England,  in  the  valleys  of  the  White 
Mountains,  or  by  the  sea-coast. 

27.  Brcnthis  Montinus  Scudd.  [Plate  A.,  Fig.   i].     The  geographical 
range  of  this  insect  has  been  sufficiently  indicated  in  the  first  part  of  this 
paper,  in  the  discussion  of  the  sub-alpine  zone.     Very  little  can  be  added 
to  what  has  already  been  published  concerning  the  seasons  of  this  insect. 
It  has  been  found  from  July  2 1  to  August  1 8.     Specimens  captured  August 
2  had  well  developed  eggs;  others  taken  August  n  were  "in  good  con 
dition."     It  is  therefore  probable,  from  analogy  with  the  other  species  of 
the  genus  inhabiting  New  England,  that  the  butterflies  first  appear  in  the 
middle  or  latter  part  of  June,  and  lay  their  eggs  about  the  middle  of 
August;  that  these  hatch  at  once,  and  that  the  embryonic  caterpillars 
hibernate,  reviving  sufficiently  in  the  spring  to  undergo  their  changes 
and  appear  on  the  wing  in  June.     Perhaps,  however,  some  of  these  cater 
pillars  become  lethargic  and  transform  later,  so  as   to  appear  on   the 
wing  in  August  (while  the  June  butterflies  are  laying  their  eggs),  for 
fresh  individuals  have  been  captured  on  August  11.     Should  observers 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  355 

find  females  at  this  date  with  undeveloped  eggs,  this  theory  would  seem 
more  plausible,  and  might  throw  some  light  on  the  origin  of  the  vernal 
series  in  the  other  species.  It  should  be  added  that,  in  Europe,  only  one 
brood  has  been  observed  among  the  mountain  species  of  this  genus. 

Probably  no  collector  has  seen  more  than  eight  or  ten  of  these  butter 
flies  in  a  day's  scramble  among  the  mountains,  but  if  sought  early  in  July 
they  might  be  found  in  greater  abundance.  They  fly  close  to  the  ground 
among  the  scanty  foliage  growing  in  the  rocky  crevices  of  the  steep 
mountain  slopes.  Messrs.  Sanborn  and  Whitney  have  often  seen  them 
on  the  mountain  willow,  Salix  hcrbacea  Linn.,  which  grows  but  a  few 
inches  above  the  ground.  So  frequent  and  prolonged  were  their  visita 
tions  to  this  plant,  that  these  observers  sought  carefully  but  in  vain  for 
eggs.  It  is  more  probable  that  the  caterpillar  feeds  upon  some  of  the 
Violaceae. 

28.  BrentJds  Bellona  Herr.-Schaff.     In  New  England  this  butterfly 
appears  to  be  as  well  distributed  and  as  common  as  B.  Myrina,  although 
elsewhere  it  is  considered  somewhat  less  abundant. 

29.  Phyciodes  Tharos  Kirb.     In  New  England  this  species  is  almost 
everywhere  exceedingly  abundant.     It  is  not  uncommon  even  in  the 
White  Mountain  district;  but  Mr.  Smith,  who  has  collected  largely  in 
Norway,  Me.,  writes  that  he  has  never  seen  a  dozen  specimens  there. 

30.  Charidryas  Nycteis  Scudd.     In  New  England  this  is  a  very  rare 
insect.     Mr.  Sanborn  has  found  a  single  specimen  in  the  Glen,  at  the 
base  of  the  White  Mountains,  and  Mr.  Smith  one  at  Walpole.     The  gen 
eral  distribution  of  this  insect  leads  us  to  anticipate  its  occurrence  any 
where  in  the  southern  half  of  New  Hampshire. 

31.  Limncecia  Harrisii  Scudd.     Specimens  of  the  imago  have  been 
taken   among  the  White  Mountains,  and   the  sides  of  the    Glen   road 
swarm  with  the  caterpillars  at  the  proper  season.     It  has  also  been  found 
at  Pittsfield  (Treat),  Dublin  (Faxon),  and  Milford,  rare  and  local  (Whit 
ney).     It  seems  to  be  more  common  in  the  elevated  and  northern  dis 
tricts  than  elsewhere,  and  has  seldom  been  found  outside  of  the  state. 

32.  Eupliydryas  Phaeton  Scudd.     This  butterfly  is  so  eminently  local 
in  its  habits  that  it  has  not  yet  been  found  over  the  extent  of  country 
which  it  probably  occupies.     In   New  England  it  is  found  abundantly

of  the  Connecticut  river  valley,  but,  owing  to  its  local  habits,  it  is  ordi 
narily  esteemed  rare.  It  occurs  only  in  moist,  or  moist  and  shady,  mead 
ows  of  small  extent.  When  young,  it  feeds  on  Chcloue  glabra;  after 
hibernating,  on  Lonicem  ciliata. 

33.  Libythca  Bachmanii  Kirtl.     Two  specimens  of  this  butterfly  have 
been  taken  at  Littleton  by  Dr.  F.  F.  Hodgman.     With  a  single  excep 
tion,  this  is  the  only  known  instance  of  its  occurrence  in  New  England. 

RURALES. 

34.  Thccla  L  iparops  LeC.     This  butterfly  appears  to  be  found  through 
out  New  England,  although  everywhere  considered  a  rare  species.     In 
New  Hampshire  it  has  only  been  reported  from  Mt.  Moriah,  Thornton 
(Faxon),  and  Milford  (Whitney). 

35.  TJiccla  Edwardsii  Saund.     Has  been  taken  only  in  the  extreme 
southern  parts  of  the  state,  Milford  (Whitney)  and  Nashua  (Harris). 

36.  TJiecla  Calamts  Doubl.     This  butterfly  seems  to  occur  throughout 
New  England.     In    New  Hampshire,  it   is   very  common   at   Walpole 
(Smith),  but  is  probably  absent  from  the  northern  and  perhaps  the  cen 
tral  parts  of  the  state,  although  it  occurs  at  Norway,  Me. 

37.  TJiecla  acadica  Edw.     This  butterfly  is  rather  widely  distributed 
in  New  England.     In  New  Hampshire  it  has  been  taken  only  at  Milford, 
"very  rare"  (Whitney),  and  at  Nashua  (Harris). 

38.  Callipareus  Melinus  Scudd.     A  widely  spread  species  that  will 
probably  be  found  in  every  part  of  the  United  States.     In  New  England 
it  is  more  abundant  in  the  south  than  in  the  north,  although  it  has  been 
taken  as  far  north  as  Norway,  Me.,  and  Plymouth,  N.  H.     Other  locali 
ties  in   New  Hampshire   are   Dublin  (Faxon),  Suncook   (Thaxter),  and 
Milford  (Whitney). 

39.  Incisalia  Augustus  Min.     The  distribution  of  this  insect  seems  to 
be  somewhat  peculiar.    Apparently  reaching  its  maximum  of  development 
in  New  England,  it  occurs  also  in  the  Canadian  fauna,  even  as  far  as  the 
Cumberland  house  on  the  Saskatchewan,  nearly  in  the  centre  of  the  con 
tinent,  and  has  been  described  from    California  as  a  distinct    species. 
Yet  notwithstanding  its  occurrence  in  California,  it  has  not  otherwise 
been  reported  in  the  United  States  west  of  Albany.     In  New  England 
it  is  widely  distributed,  and  will  probably  be  found  in  abundance  all  over 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  357 

the  wilder  portion.  It  has  not  been  reported  from  the  White  Mountains, 
and  its  northernmost  known  station  is  Norway,  Me.,  very  common 
(Smith).  In  Milford,  N.  H.,  it  is  rather  uncommon.  (Whitney). 

40.  Incisalia  Niphon  Min.     In  New  England  this  butterfly  has  been 
found  in  widely  separated  localities,  more  abundantly  at  the  south  than 
at  the  north.     It  has  been  taken  in   Norway,  Me.  (Smith),  the  White 
Mountains  (Sanborn),  and  Milford,  N.  H.,  common  (Whitney). 

41.  Incisalia  Irns  Scudd.     The  only  known  locality  for  this  butterfly 
in  New  Hampshire  is  Milford,  where  it  is  scarce  (Whitney). 

42.  Strymou   Titus  Butl.     In  New  England  it  is  considered  a  rare 
insect,  but  has  occasionally  been  found  in  considerable  numbers,  and  is 
well  distributed  at  least  over  the  southern  portions.     The  only  northern 
locality  in  which  it  has  been  found  is  Norway,  Me.,  where  it  occurs  in 
abundance  (Smith).     In  New  Hampshire  it  has  been  taken  only  at  Mil- 
ford,  not  common  (Whitney). 

43.  Cyaniris  neglecta  Scudd.     This  butterfly  is  found  across  the  con 
tinent.     We  may  therefore  naturally  presume  that  it  is  found  throughout 
New  England.     It  is  common  in  the  southern  half,  but  it  is  not  often 
reported  from  the  northern  portions ;  perhaps,  however,  this  is  rather  due 
to  the  lack  of  observers.     Our  northernmost  recorded  localities  are  Nor 
way,  Me.  (Smith),  and  Dublin,  N.  H.,  "quite  plenty"  (Faxon). 

44.  Cyaniris  violacea  Scudd.     This  is    by  no  means   an   uncommon 
insect  in  New  England,  but  has  generally  been  mistaken  for  one  of  the 
other  species  (coming,  as  it  does,  midway  between  neglecta  and  Lucia), 
on  account  of  the  absence  in  New  England  of  the  dark  form  of  the 
female.     Probably  it  will  prove  comparatively  rare  in  the  northern  half. 
It  has  been  taken  at  Walpole  and  Milford. 

45.  Cyaniris  Lucia  Scudd.     This  is  an  abundant  insect  throughout  the 
northern  half  of  New  England,  and  cannot  be  called  very  uncommon 
even  in  Massachusetts. 

46.  Evcres  Comyntas  Scudd.  is  found  throughout  New  England,  even 
in   the  White  Mountain  district,  and  is  everywhere  a  common  insect, 
especially  in  the  southern  half. 

47.  Chrysophanus  Hyllus  Hiibn.     In  New  England  it  has  never  been 
taken  east  of  the  Connecticut  valley;  and  in  New  Hampshire  only  at 
Walpole,  a  single  specimen  (Smith). 


PHYSICAL    GEOGRAPHY. 

48.  Chrysophanus  epixanthe  Westw.     In  New  England  this  butterfly 
has  only  been  found  east  of  the  Connecticut  valley.     In  New  Hampshire 
it  has  been  taken  at  Milford,  very  plentiful  in  a  few  localities  (Whitney), 
Suncook,  not  common  (Thaxter),  and  Hampton,  abundant  (Scudder). 

49.  Lyccena  aincricana  Harr.     It  is  found  throughout  New  England, 
almost  as  abundantly  in  the  White  Mountain  district  as  elsewhere,  and  is 
one  of  our  commonest  species. 

50.  Feniscca   Tarqninius  Grote.     The  latitudinal  distribution  of  this 
butterfly  is  greater  than  that  of  any  other  of  the  American  coppers,  since 
it  is  found  from  beyond  the  limits  of  the  Alleghanian  fauna  on  the  north 
to  the  shores  of  the  Gulf  of  Mexico.     In  New  Hampshire  it  has  been 
taken  at  Berlin  Falls,  Thornton,  "very  abundant  below  the  cascade  on 
Mill  brook"  (Faxon),  Waterville,  Manchester,  and  Milford. 


PAPILIONimE. 


51.  Colias  PJiilodice  God.     In  New  England  this  butterfly  is  every 
where  the  commonest  species,  except  in  certain  years,  when  it  seems  to 
be  affected  by  some  unfavorable  circumstances.     It  is  found  alike  in  the 
White  Mountain  region  and  on  the  shores  of  the  Sound,  but  is  more 
abundant  in  the  southern  than  in  the  northern  districts. 

52.  Eurema  Lisa  Kirb.     This  butterfly  is  a  member  of  the  Carolinian 
fauna,  where  it  is  very  abundant.     A  single  specimen  has  been  taken  by 
Mr.  Thaxter  at  the  Isles  of  Shoals. 

53.  Ganoris  rapce  Dalm.     This  butterfly  is  our  most  recent  and  least 
desirable  importation  from  the  old  world,  and  before  many  years  it  will 
doubtless  spread  over  the  whole  northern  hemisphere.     It  was  introduced 
at  Quebec,  and  has  rapidly  spread  southward  and  westward.     The  first 
specimens  taken  near  New  Hampshire  were  captured  by  Mr.  Merrill,  at 
Waterbury,  Vt,  in  August,  1867;  yet  it  was  only  in  May  of  the  same 
year  that  they  appeared  at  Montreal.     In  August,  1868,  they  were  not 
uncommon  at  Island  Pond,  on  the  Grand  Trunk  Railway,  and  the  suc 
ceeding  year  were  taken  in  July  by  Mr.  Sanborn,  at  Littleton,  and  by  Mr. 
Whorf,  at  Shelburne,  and,  in  August,  as  far  south  as  Campton,  by  the 
latter  gentleman.     It  was  not  until  September  of  the  same  year  that  they 
were  discovered  at  Norway,  Me.,  a  few  miles  from  Shelburne;  and  yet 
they  were  taken  at  Waterville,  in  the  same  state,  in  May  of  that  year, 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  359 

and  still  farther  south,  at  Lewiston,  even  in  the  previous  year!  In  1870, 
the  vanguard  of  the  army  crossed  the  state,  reaching  Milford  in  May,  but 
they  had  even  then  penetrated  as  far  as  Springfield,  in  their  march  down 
the  Connecticut,  and  were  abundant  at  Walpole.  They  swarm  now  in 
every  part  of  the  state,  not  even  excepting  the  Isles  of  Shoals,  where  Mr. 
Thaxter  found  them  in  1870,  and  the  alpine  zone  of  the  White  Mountains, 
where  I  took  fresh  specimens  in  1873. 

54.  Ganoris  olcracca  Scudd.     [Plate  A,  Fig.  8.]     It  is  found  through 
out    New   England,    although    seldom    abundant   south    of    the   annual 
isotherm  of  48°.     Northward  and  eastward  it  is  everywhere  abundant, 
and  continues  to  be  so  as  far  south  as  Williamstown,  Mass.,  Dublin, 
N.  H.,  and  Portland,  Me.     It  rarely  occurs  south  of  the  northern  bound 
ary  of  Connecticut. 

55.  Lacrtias  PJiilenor  Hubn.     [Plate  A,  Fig.  15,  chrysalis,  side  view. 
Fig.  17,  ib.,  dorsal  view.]     In  New  England  this  butterfly  is  very  rare. 
In  no  locality  has  more  than  a  single  specimen  been  taken  during  a  sea 
son,  excepting  near  New  Haven ;  one  was  taken  and  another  seen  by 
Mr.  Smith,  at  Walpole,  N.  H.,  in  1870. 

56.  Pterourus   Troilus  Scudd.      In  New  England  this   insect  is  not 
uncommon  in  the  three  southern  states,  and  has  been  found  north   of 
Massachusetts,  at   Milford,   not   as    common   as    Polyxenes    (Whitney), 
Dublin   (Faxon),   and  Walpole,    N.    H.    (Smith),   and   at    Sudbury,  Vt, 
scarce  (Scudder). 

57.  Euphceadcs  Glaucus  Hiibn.     [Plate  A,  Fig.  16.]     This  butterfly  is 
more  widely  distributed  than  any  other  of  our  swallow-tails,  for  it  is 
found  in  nearly  every  part  of  North  America,  from  the  Atlantic  to  the 
Pacific,  from  Newfoundland  to  northern  Florida,  and  from  central  Alaska 
to  California.     Its  northern  limit  in  the  eastern  half  of  the  continent 
closely  follows  the  dividing  line  between  the  Canadian  and  Huronian 
faunas,  as  laid  down  by  Allen.     In  New  England  it  is  everywhere  com 
mon,  from  the  summit  of  Mt.  Washington  to  Long  Island  sound,  but  is 
more  abundant  in  the  northern  than  in  the  southern  districts.     In  the 
White  Mountain  region  it  is  exceedingly  abundant,  and  individuals  are 
often  dusky  and  small,  like  those  from  Alaska. 

58.  Amaryssus   Polyxenes  Scudd.     This    insect    is   rather    uniformly 
common  throughout  New  England,  although  not  mentioned  by  Gosse 


36O  PHYSICAL    GEOGRAPHY. 

among  the  butterflies  of  Compton,  Lower  Canada,  which  is  rather  strange, 
since  it  is  found  in  the  valleys  of  the  White  Mountains. 


URBICOL/E. 


59.  Epargyreus  Tityrns  Scudd.     This  is  a  tolerably  common,  some 
times  abundant  species  in  the  three  southern  New  England  states,  occur 
ring  even  in  the  elevated  portions.     North  of  this  it  becomes  rare,  having 
been  taken  in  New  Hampshire  only  at  Milford,  "plenty"  (Whitney),  Dover 
(Faxon),  Walpole  (Smith),  and  Plymouth  (Scudder). 

60.  Achalarus  Lycidas  Scudd.     This  is  a  rare  insect  in  New  England. 
It  has  occasionally  occurred  in  abundance  in  New  Haven  and  vicinity, 
and  a  few  specimens  are  reported  at  rare  intervals  in  various  parts  of 
Massachusetts.     Mr.  Whitney  has  taken  three  or  four  specimens  at  Mil- 
ford,  the  northernmost  known  locality  for  this  insect. 

61.  Thorybes  Py lades  Scudd.     It  is  found  in  abundance  in  every  part 
of  New  England. 

62.  Erynnis  Persius  Scudd.     In  New  England  it  is  everywhere  com 
mon,  from  the  valleys  of  the  White  Mountains  and  Norway,  Me.,  to  Cape 
Cod,  Norwich,  and  New  Haven. 

63.  Erynnis  Lucilius  Scudd.     This  insect  has  not  been  recorded  from 
New  Hampshire ;  but  I  have  found  empty  nests  of  the  larva  among  the 
leaves  of  Aquilegia  in  Plymouth,  which  must  have  been  made  by   this 
species. 

64.  Erynnis  Icelus  Scudd.     It  is  widely  spread  over  New  England, 
having  been  taken  at  nearly  every  place  where  there  are  resident  col 
lectors.     In  the  north  it  has  been  found  in  the  wilds  of  Maine,  at  Norway 
in  the  same  state,  in  the  valleys,  and  even  in  the  sub-alpine  zone  of  the 
White  Mountains,  at  Plymouth,  and  farther  south  at  Milford. 

65.  Erynnis  Brizo  Scudd.     This,  too,  is  widely  spread  in  New  England, 
but  has  not  yet  been  found  in  the  White  Mountain  valleys,  although  it  has 
been  taken  at  Waterville,  Me.,  and  Thornton,  N.  H.     It  has  also  been 
reported  from  Dublin  and  Milford,  in  the  southern  part  of  New  Hamp 
shire. 

66.  Erynnis  Jnvenalis    Scudd.      This    butterfly   is   confined    in   New 
England  to  the  three  southern  states,  having  been  taken  north  of  them 
in  but  a  single  locality  (Milford,  N.  H.),  where  it  is  reported  rare. 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  361 

67.  Pliolisora  Catullus  Scudd.     In  New  England  this  is  not  an  uncom 
mon  insect  in  some  southern  localities,  notably  along  the  Connecticut 
river.     Its  northernmost  recorded  locality  is  Milford,  N.  H.,  very  rare 
(Whitney). 

68.  Ancyloxypha  Numitor  Feld.     In  New  England  this  smallest  of  our 
butterflies  is  abundant  south  of  the  latitude  of  42°  30',  but  has  been 
recorded  from  only  a  single  locality  north  of  it,  Milford,  N.  H.     As  it  is 
said  to  be  common  there,  it  will  probably  be  found  somewhat  farther 
north. 

69.  Amblyscirtcs  vialis   Scudd.     In    New    England   this   butterfly   is 
strictly  limited  to  the  southern  half,  having  been  found  but  once  north  of 
Massachusetts,  at  Milford,  N.  H.  (Whitney). 

70.  Amblyscirtes  Samoset  Scudd.     In  New  England  it  is  found  in  such 
northern  and  elevated  localities  as  Norway,  Me.,  and  the  valleys  of  the 
White  Mountains.     It  has  also  been  taken  at  Milford,  and  once  only  in 
Massachusetts. 

71.  Cyclopides  Mandan  Scudd.      In  New  England  this  butterfly  has 
been  taken  but  twice, — once  in  Norway,  Me.  (Smith),  and  once  in  the 
Glen,  White  Mountains  (Sanborn). 

72.  Ocytcs  Metea  Scudd.     This  is  another  of  the  many  southern  but 
terflies,  whose  northernmost  known  limit  is  Milford,  N.  H. 

73.  Poanes  Massasoit  Scudd.     Excepting  in  New  England  this  butter 
fly  has  not  been  taken  north  of  Albany;  in  New  England,  although 
otherwise  confined  to  the  more  southern  portions,  and  especially  to  the 
lower  levels,  it  has  been  taken  at  Milford,  N.  H. 

74.  Atrytone  Zabulon  Scudd.     This  common  butterfly  is  taken  through 
out  New  England,  in  the  southern  parts  of  which  it  is  exceedingly  abun 
dant.     It  is.  even  common  in  such  northern  and  elevated  localities  as 
Williamstown,  Mass.,  Norway,  Me.,  and  Thornton  and  Plymouth,  N.  H.; 
it  extends  to  Quebec  and  Nova  Scotia. 

75.  Pamphila  Sassacus  Kirb.     This  butterfly  occurs  everywhere  in  the 
southern  half  of  New  England,  but,  excepting  at  Norway,  Me.,  has  not 
been  taken  in  the  northern  half.     Mr.  Whitney  has  found  it  at  Milford. 

76.  AntJiomastcr  Leonardus  Scudd.     This  butterfly  also  is  confined  in 
New  England  to  the  southern  half,  the  northernmost  localities  from  which 
it  is  recorded  being  Dublin  (Faxon)  and  Milford,  N.  H.  (Whitney). 

VOL.  i.    48 


362  PHYSICAL    GEOGRAPHY. 

77.  Polites  Peckius  Scudd.     In  New  England  it  is  everywhere  the 
commonest  of  the  Astyci,  and  is  found  throughout  every  portion  of  the 
district,  from  the  White  Mountains  to  the  sea-coast. 

78.  Hcdone  SEtna  Scudd.     It  is  found  in  the  southern  half  of  New 
England;  once,  however,  a  specimen  was  taken  in  Norway,  Me.     With 
that  exception,  its  northernmost  range  is  indicated  by  its  capture  in  Wai- 
pole  and  Milford,  N.  H. 

79.  LimocJiores  Mystic  Scudd.     It  is  found  everywhere  in  New  Eng 
land,  from  the  White  Mountains  to  Cape  Cod  and  New  Haven.     There 
is  hardly  a  local  collection  of  any  size  that  does  not  contain  it. 

80.  LimocJiores  bimacula  Scudd.     It  has  seldom  been  taken  in  New 
England,  and  never  north  of  Massachusetts,  except  at   Milford,  N.  H., 
where  it  is  rare. 

8 1.  LimocJiores  Manataaqua  Scudd.      In  New  England  it  has  been 
found  only  in  widely  separated  localities.     Among  these,  and  one  of  the 
most  northern,  is  Walpole,  N.  H.,  where  Mr.  Smith  found  it  somewhat 
common. 

82.  LimocJiores  Taumas  Scudd.     This  butterfly  is  found  over  perhaps 
a  larger  extent  of  territory  than  any  other  species  of  its  tribe.     In  New 
England  it  is  everywhere  common,  from  the  White  Mountains,  and  even 
from  its  highest  altitudes,  to  the  southern  and  eastern  sea-coast. 

83.  EitpJiyes  Mctacomet  Scudd.     This  insect  is  widely  spread  in  New 
England,  although  it  has  been  taken  but  rarely  in  its  northern  half;  it 
has  been  taken  at  Norway,  Me.,  and  Thornton,  N.  H.,  and  is  not  uncom 
mon  at  Plymouth,  Walpole,  and  Milford.     South  of  these  latter  points 
it  is  everywhere  rather  common  and  sometimes  abundant. 

84.  EupJiyes  -vcrna  Scudd.      In  New  England   it  is  confined  to  the 
Alleghanian  region,  and  is  everywhere  exceedingly  rare.     A  single  speci 
men  has  been  taken  at  Milford  by  Mr.  Whitney. 

85.  Lerema  Hianna  Scudd.     This  member  of  the  Alleghanian  fauna 
has  thus  far  been  detected  in  New  England  in  only  a  few  localities.     It  is 
confined  to  its  southern  portions,  but  has  been  found  to  be  somewhat 
common  at  Milford  by  Mr.  Whitney. 

III.  LIST  OF  THE   ORTHOPTERA   OF  NEW  HAMPSHIRE,  WITH   NOTES  ON 
THEIR  GEOGRAPHICAL  DISTRIBUTION  AND  STRIDULATION. 

In  the  following  pages  I  have  given  a  list  of  all  the  species  known  to 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  363 

me  to  inhabit  the  state,  adding  notes  upon  their  geographical  distribution 
both  within  and  without  the  state.  Such  information  is  given  concern 
ing  the  mode  and  character  of  their  stridulation  as  could  be  obtained. 
Unfortunately  most  of  the  material  for  the  list  has  been  collected  about 
the  White  Mountains  only  in  excursions  made  by  my  friends  and  myself. 
This  accounts  for  its  poverty. 

GRYLLIDES. 

1.  Gryllotalpa  borealis  Burm.  [Plate  A,  Fig.  7.]     The  northern  mole- 
cricket  inhabits  nearly  the  whole  of  the  United  States  east  of  the  great 
plains,  from  Louisiana  to  Massachusetts.     It  has  not  yet  been  discovered 
in  New  Hampshire,  but  it  will  doubtless  be  found  in  the  southern  portions 
of  the  state,  as  it  is  not  at  all  uncommon  in  the  region  about  Boston  and 
Springfield,  Mass.,  and  has  been  taken  by  Prof.  Verrill,  at  Anticosti.     The 
figure  has  been  introduced  upon  the  plate,  to  call  the  attention  of  those 
interested,  and   because  it  is  one  of    the  most  peculiar  forms   among 
Orthoptera.     It  is  a  burrowing  insect,  as  the  character  of  the  forelegs 
readily  indicates.     At  Winter  pond,  Winchester,  Mass.,  the  whole  surface 
of  the  ground  beneath  the  sod  and  stones  for  a  rod  from  the  water's  edge 
is  completely  honeycombed  with  their  burrows.     They  seldom  penetrate 
to  a  depth  of  more  than  six  or  eight  inches,  rarely  to  a  foot  beneath  the 
surface.     The  burrows  are  usually  about  a  third  of  an  inch  in  diameter, 
entirely  irregular  in  direction,  and  often  terminate  abruptly.     Where  the 
ground  is  hard  the  burrows  are  brought  so  near  the  surface  as  to  raise 
long  ridges  of  mould,  which,  when  dry,  frequently  fall  in  and  expose 
the  burrows.     The  note  of  this  insect  is  most  frequently  heard  at  dusk, 
and  resembles  the  distant  sound  of  frogs,  but  is  somewhat  feebler. 

2.  Gry Hits  luctuosus  Serv.     This  insect  is  readily  distinguished  from  all 
other  species  of  the  genus  found  in  this  part  of  the  country  by  the  great 
length  of  the  wings,  which  extend  far  beyond  the  body  and  the  elytra.     It 
has  been  taken  in  New  Hampshire  by  Mrs.  F.  W.  Putnam,  and  is  not 
infrequent  even  so  far  north  as  the  valleys  of  the  White  Mountains.    The 
individuals  from  this  locality  are  much  smaller  than  farther  south. 

Other  species  of  this  genus  doubtless  occur  in  New  Hampshire,  but  I 
do  not  happen  to  possess  specimens  for  determination.  At  Jefferson,  in 
1867,  no  chirp  of  a  Gryllus  was  heard  until  August  12,  although  they 
often  commence  their  song  in  Massachusetts  in  June.

3.  Nemobius  vittatus  Harr.  is  found  all  over  the  state,  even  in  the  White 
Mountain  region,  and  extends  west  as  far  as  Nebraska,  and  south  at  least 
to  Maryland.  It  appears  a  little  earlier  than  the  species  of  Gryllus,  but 
in  the  White  Mountains  not  until  August.  Its  chirp  is  very  similar  to 
that  of  Gryllus,  and  can  best  be  expressed  by  ru  or  rruu,  pronounced  as

Note  of  Nemobius  vittatus. 

though  it  were  a  French  word.  The  note  is  trilled  forcibly,  and  lasts  a 
variable  length  of  time,  sometimes  for  several  seconds;  at  others  it  is 
reduced  to  a  short,  sharp  click.* 

I  once  observed  one  of  these  insects  singing  to  its  mate.  At  first  the 
song  was  mild,  and  frequently  broken ;  afterward  it  grew  impetuous, 
forcible,  and  more  prolonged ;  then  it  decreased  in  volume  and  extent  till 
it  became  quite  soft  and  feeble.  At  this  time  the  male  began  to  approach 
the  female,  uttering  a  series  of  twittering  chirps ;  the  female  ran  away, 
and  the  male,  after  a  short  chase,  returned  to  his  old  haunt,  singing 
with  the  same  vigor  as  before,  but  with  more  frequent  pauses ;  at  last, 
finding  all  persuasion  unavailing,  he  brought  his  serenade  to  a  close. 
The  pauses  of  his  song  were  almost  instantly  followed  by  a  peculiar  jerk 
of  the  body ;  it  consisted  of  an  impulsive  movement  backward,  and  then 
as  suddenly  forward,  and  was  accompanied  by  a  corresponding  movement 
of  the  antennae  together,  and  then  apart.  The  female  was  near  enough 
to  be  touched  by  the  antennae  of  the  male  during  the  first  movement,  and 
usually  started  in  a  nearly  similar  way  as  soon  as  touched. 

The  elytra  of  the  male  are  held  at  an  angle  of  about  twenty  degrees 
from  the  body  during  stridulation,  and,  perhaps,  at  a  slightly  greater 
angle  from  each  other.  Even  when  most  violent,  the  sound  is  produced 

*  It  is  necessary  for  me  to  describe  the  peculiar  system  of  musical  notation  which  I  have  adopted.  Each  bar 
represents  a  second  of  time,  and  is  occupied  by  the  equivalent  of  a  semibreve ;  consequently  a  quarter  note  (t\ 
or  a  quarter  rest  (\*)  represents  a  quarter  of  a  second  ;  a  sixteenth  note  /f\  or  a  sixteenth  rest  /  Jf\  a  sixteenth 

of  a  second,  etc.  For  convenience'  sake,  I  have  introduced  a  new  form  of  rest  ("^Bl  or  B^"),  which  indicates 
silence  through  the  remainder  of  a  measure. 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  365 

by  the  friction  of  the  inner  edges  of  the  elytra  only,  not  by  the  whole 
surface. 

4.  Nemobius  fasciatus  Scudd.     This  cricket  may  prove  to  be  only  a 
long-winged  form  of  the  preceding,  as  it  scarcely  differs  from  it  in  anything 
but  the  length  of  these  organs.     It  is  also  found  throughout  New  Hamp 
shire,  even  in  the  White  Mountain  region.     It  occurs  as  far  south  as 
South  Carolina,  Louisiana,  and  Texas,  and  west  at  least  to  Missouri.     I 
have  not  noticed  any  difference  between  the  chirp  of  this  species  and  of 
the  preceding. 

5.  CEcantJius  niveus  Serv.  is  probably  found  in  the  southern  portions 
of  the  state,  although  no  record  of  its  occurrence  has  fallen  under  my 
notice.     It  is  certainly  found  in  the  neighboring  parts  of  Massachusetts. 
This  insect  does  great  damage  to  young  shoots  of  raspberry,  blackberry, 
and  even  of  the  grape-vine,  by  depositing  its  eggs  within  the  stem ;  these 
are  laid  in  a  nearly  perpendicular  row,  often  a  foot  long,  at  short  distances 
apart,  a  single  egg  being  introduced  through  each  hole  into  the  very 
heart  of  the  stem,  weakening  it  to  such  a  degree  that  it  is  apt  to  break 
in  a  strong  wind.     A  European  species,  thought  by  some  to  be  identical 
with  this,  has  a  slightly  different  habit,  and  is  far  less,  if  at  all,  injurious. 
It  makes  its  punctures  much  farther  apart,  and  introduces  two  or  three 
eggs  into  each  opening. 

The  day-song  of  this  insect  is  exceedingly  shrill,  and  may  be  repre 
sented  by  the  following  figure,  though  the  notes  vary  in  rapidity.     When

slowest  they  are  about  sixteen  a  second.  The  song  is  of  varied  length, 
sometimes  lasting  but  two  or  three  seconds,  sometimes  continuing  a 
minute  or  two  uninterruptedly ;  it  is  a  nearly  uniform,  equally  sustained 
trill,  but  the  insect  often  commences  its  note  at  a  different  pitch  from  the 
normal  one,  as  if  it  required  a  little  practice  to  attain  it.  When  singing,

the  tegmina  are  raised  at  fully  a  right  angle  to  the  body.  The  night-song 
consists  of  tJirrr  repeated  incessantly,  three  parts  of  song  and  one  of 
rest  in  every  three  seconds.

LOCUSTARLE. 

6.  Ceuthophilus  maculatus  Scudd.  is  found  throughout  New  England 
and  as  far  south  as  Maryland.     I  once  took  a  specimen  half  way  up  Mt. 
Washington.     All  the  Vermont  specimens   I  have  seen  are  unusually 
dark. 

7.  PJiylloptera  oblongifolia  Burm.  has  not  been  found  in  the  state,  but 
as  it  occurs  somewhat  abundantly  in  Massachusetts,  and  is  found  as  far 
west  as  Iowa,  it  doubtless  inhabits  at  least  the  southern  part  of  New 
Hampshire.     I  have  not  studied  its  note  attentively,  but  if  I  recollect 
aright,  it  gives  three  rapid  notes  in  succession  like  the  katydid. 

8.  PJianeroptera  curvicauda  Serv.     This  insect  is  found  all  over  the 
state,  even  inhabiting  the  sub-alpine  zones  of  the  White  Mountains.     It 
is  found  also  as  far  south  as  the  Carolinas,  and  west  to  the  Red  river  set 
tlements  of  British  America,  to  Michigan,  and  Illinois.     It  is  more  noisy 
by  night  than  by  day;  and  the  songs  differ  considerably  at  these  two 
times.     The  day-song  is  given  only  during  sunshine,  the  other  by  night 
and  in  cloudy  weather.     I  first  noticed  this  while  watching  one  of  these 
little  creatures  close  beside  me ;  as  a  cloud  passed  over  the  sun,  he  sud 
denly  changed  his  note  to  one  with  which  I  was  already  familiar,  but 
without  knowing  to  what  insect  it  belonged.     At  the  same  time,  all  the 
individuals  around  me  whose  similar  day-song  I  had  heard,  began  to 
respond  with  the  night  cry :  the  cloud  passed  away,  and  the  original  note 
was  resumed  on  all  sides.     Judging  that  they  preferred  the  night-song  to 
that  of  the  day,  from  their  increased  stridulation  during  the  former  period, 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  367 

I  imitated  the  night-song  during  sunshine,  and  obtained  an  immediate 
response  in  the  same  language.  The  experiment  proved  that  the  insects 
could  hear  as  well  as  sing. 

This  species  is  exceedingly  shy,  and  the  observer  must  be  patient  who 
would  hold  converse  with  it.  One  insect  which  I  had  disturbed,  and 
beside  which  I  was  standing,  could  not  at  first  decide  to  resume  his  song ; 
he  was  afraid  of  the  intruder,  but,  enticed  by  a  neighboring  songster,  gave

utterance  several  times  to  a  barely  discernible,  short  click  or  tl;  after  five 
or  six  of  these  efforts  his  desires  overcame  his  fears.  The  note  by  day  is 
bzrwi,  and  lasts  for  one  third  of  a  second. 

The  night-song  consists  of  a  repetition,  ordinarily  eight  times,  of  a 
note  which  sounds  like  tchw.  It  is  repeated  at  the  rate  of  five  times  in

three  quarters  of  a  second,  making  each  note  half  the  length  of  the  day 
note. 

9.  Conocephalus  ensiger  Harr.  Found  throughout  New  England,  even 
into  the  sub-alpine  zone  of  the  White  Mountains ;  it  extends  south  as  far 
as  the  middle  states  and  southern  Illinois,  and  west  to  Nebraska,  Minne 
sota,  and  the  Red  river  of  the  north.  Mr.  Smith  found  a  female  of  this 
insect  "with  the  ovipositor  forced  down  between  the  root-leaves  and  the 
stalk  of  the  Andropogon,  where  the  eggs  are  probably  deposited." 

There  is  a  species  of  Conocephalus  (C.  robustus  Scudd.),  found  on  the 
southern  sea-beaches  of  New  England,  which  is  exceedingly  noisy,  and 
sings  equally,  and,  I  believe,  similarly,  by  day  and  night.  The  song 
resembles  that  of  the  harvest  fly,  Cicada  canicularis.  It  often  lasts  for 
many  minutes,  and  seems,  at  a  distance,  to  be  quite  uniform ;  on  a  nearer 
approach,  one  can  hear  it  swelling  and  decreasing  in  volume,  while  there

is  a  corresponding  muscular  movement  from  the  front  of  the  abdomen 
backward,  two  and  a  half  times  a  second.  This  is  accompanied  by  a 
buzzing  sound,  quite  audible  near  at  hand ;  it  resembles  the  humming  of 
a  bee,  or  the  droning  of  a  bagpipe. 

C.  ensiger  also  seems  to  have  a  single  song,  but  it  stridulates  only  by 
night  or  during  cloudy  weather ;  it  commences  its  song  as  soon  as  the 
sky  is  obscured  or  the  sun  is  near  the  horizon ;  it  begins  with  a  note  like 
briv,  then  pauses  an  instant  and  immediately  emits  a  rapid  succession  of 
sounds  like  ckwl  at  the  rate  of  about  five  per  second,  and  continues  them 
for  an  unlimited  time.  Either  the  rapidity  of  the  notes  is  variable, 
becoming  sometimes  as  frequent  as  twenty-three  in  three  seconds,  or 
else  there  is  some  deceptive  character  in  its  song.  In  a  number  of

instances  I  have  counted  the  notes  as  rapid  as  the  highest  rate  given 
above,  but  on  a  nearer  approach  to  verify  them  the  rate  was  invariably 
reduced  to  five  per  second ;  it  is  doubtful  whether  this  was  due  to  alarm 
at  my  approach,  for  this  is  the  least  shy  of  all  our  Locustarians. 

10.  XipJiidium  fasciatum  Serv.  It  is  found  from  the  valleys  of  the 
White  Mountain  region  southward,  as  far  as  Maryland  and  southern 
Illinois.  Its  note  resembles  that  of  Orchelimum,  but  is  exceedingly  faint. 

n.  Xiphidium  brevipenne  Scudd.  This  species  has  much  the  same 
distribution  as  the  preceding,  but  is  not  recorded  from  points  so  far  south, 
although  it  reaches  Pennsylvania  and  Michigan.  One  year  its  first 
appearance  was  recorded  about  Boston,  July  i6th;  another  year  in  the 
neighborhood  of  Jefferson,  White  Mountains,  August  8th. 

12.  Orchelimum  vulgare  Harr.  This  insect  is  found  through  all  the 
White  Mountain  region,  even  to  the  alpine  zone,  and  also  over  the  rest  of 
the  state.  It  is  everywhere  very  abundant,  as  its  name  indicates.  It  is 
also  found  southward  at  least  as  far  as  Maryland  and  southern  Illinois, 
probably  also  to  the  Carolinas.  There  is  not  so  great  disparity  in  the  time

of  its  appearance  in  the  White  Mountain  region  and  in  southern  New 
England,  as  in  some  other  species.  One  year  it  appeared  in  Jefferson, 
July  28,  and  the  following  year  about  Boston,  July  15.

there  is  a  crescendo  movement,  which  reaches  its  volume  in  half  a  second  ; 
the  trill  is  then  sustained  for  a  period  varying  from  one  to  twenty  seconds 
(generally  from  six  to  eight  seconds),  and  closes  abruptly  with/.  This 
strain  is  followed  by  a  series  of  very  short  staccato  notes  sounding  like 
jip!  repeated  at  half-second  intervals;  the  staccato  notes  and  the  trill 
alternate  ad  libitum.t  The  staccato  notes  may  be  continued  almost  indefi 
nitely,  but  are  very  rarely  heard  more  than  ten  times  in  succession  ;  it 
ordinarily  occurs  three  or  four  times  before  the  repetition  of  the  phrase, 
but  not  more  than  two  or  three  times  when  the  phrase  is  not  repeated. 
I  have  known  it  to  be  entirely  omitted,  even  before  the  repetition  of  a 
phrase.  The  interval  between  the  last////  and  the  recommencement  of 
the  phrase  never  exceeds  one  quarter  of  a  second.  The  night-song  differs 
from  that  of  the  day  in  the  rarer  occurrence  of  the  immediate  notes  and 
the  less  rapid  trill  of  the  phrase  ;  the  pitch  of  both  is  at  B  flat. 

13.  TJiyrconotits  dorsalis  Scudd.     I  have  taken  a  single  specimen  of 
this  insect  as  far  north  as  Sudbury,  Vt.;  and  since  it  also  occurs  in 
eastern  Massachusetts,  it  will  no  doubt  be  found  within  the  limits  of  New 
Hampshire  in  the  Connecticut  valley.

14.  Chlocaltis  conspersa  Harr.    This  is  a  northern  insect,  extending  from

that  I  formerly  described  it  under  a  distinct  generic  name.     Its  song  is 


ftrtttt

of  varied  rapidity,  according  to  the  amount  of  sunshine;  in  the  sun  it 
makes  from  nine  to  twelve  notes,  at  the  rate  of  fifty-three  in  fifteen 
seconds  ;  the  usual  number  of  notes  is  ten. 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  3/1 

In  the  shade  the  rate  falls  to  forty-three  in  fifteen  seconds,  the  num 
ber  of  notes  remaining  the  same. 

The  femur  is  evidently  scraped  gently  upon  the  elytron  to  produce  the 
sound,  for  frequently,  at  the  commencement,  two  or  three  noiseless  move 
ments  are  made,  the  leg  failing  to  touch  the  wing-cover.  I  once  found 
three  males  singing  to  a  single  female,  who  was  busily  engaged  laying 
eggs  in  a  stick  of  wood,  her  abdomen  plunged  into  a  hole  she  had  bored 
to  the  depth  of  half  an  inch ;  two  of  the  males  were  near  enough  each 
other  to  cross  antennae. 

Mr.  S.  I.  Smith  gives  an  interesting  account  of  the  habits  of  this 
species  in  the  Proceedings  of  tJie  Portland  (Me.)  Society  of  Natural 
History. 

The  eggs  are  deposited  in  old  logs,  in  the  under  sides  of  boards,  or  in  any  soft 
wood  lying  among  the  grass  which  these  insects  inhabit.  By  means  of  the  anal 
appendages,  the  female  excavates  in  the  wood  a  smooth,  round  hole,  about  an  eighth  of 
an  inch  in  diameter.  This  hole  is  almost  perpendicular  at  first,  but  is  turned  rapidly 
off  in  the  direction  of  the  grain  of  the  wood,  and  runs  nearly  parallel  with,  and  about 
three  eighths  of  an  inch  from,  the  surface, — the  whole  length  of  the  hole  being  an 
inch  or  an  inch  and  a  fourth.  A  single  hole  noticed  in  the  end  of  a  log  was  straight. 
The  eggs,  which  are  about  a  fourth  of  an  inch  in  length,  quite  slender,  and  light 
brownish  yellow,  are  placed  in  two  rows,  one  on  each  side,  and  inclined  so  that, 
beginning  at  the  end  of  the  hole,  each  egg  overlies  the  next  in  the  same  row  by  about 
half  its  length.  The  aperture  is  closed  by  a  little  disk  of  a  hard,  gummy  substance. 
I  have  seen  many  of  the  females  engaged  in  excavating  the  holes,  and  they  always 
stood  with  the  body  in  the  direction  of  the  grain  of  the  wood,  and  apparently  did  not 
change  their  position  during  the  operation.  When  one  was  just  beginning  a  hole,  it 
was  very  easy  to  see  the  upper  appendages  rise  and  open,  and  each  time  scrape  away  a 
little  of  the  wood.  During  this  operation  a  frothy  fluid  is  emitted  from  some  part  of 
the  abdomen,  but  whether  it  serves  to  soften  the  wood,  or  to  lubricate  the  appendages 
and  the  sides  of  the  hole,  I  did  not  determine.  There  were  always  great  numbers  of 
half  finished  holes,  or  those  just  begun,  and  comparatively  very  few  that  were  com 
pleted  ;  and  I  have  often  found  upon  the  under  side  of  boards  great  numbers  of  the 
holes  just  begun,  none  of  them  being  more  than  an  eighth  of  an  inch  in  depth.  Per 
haps  the  reason  for  so  few  holes  being  finished  is,  that  the  wood  proves  too  hard,  and 
the  insect  tries  for  a  softer  place,  or,  many  of  them  may  be  disturbed  during  the  oper 
ation.  When  they  had  opened  the  hole  only  to  a  slight  depth,  they  leaped  away  if 
disturbed  ;  but  when  the  abdomen  was  quite  a  distance  into  the  nearly  completed  hole, 
they  seldom  attempted  to  withdraw  it  even  after  the  hand  was  upon  them. 

I  have  also  noticed  that  this  insect  is  not  easily  suited  in  choosing  the 


372  PHYSICAL    GEOGRAPHY. 

best  place  to  bore  her  nest ;  the  wood  must  be  firm  enough  to  retain  the 
eggs  well  in  place,  and  soft  enough  to  absorb  much  moisture  in  the  spring. 
Upright  pieces  of  timber  are  never  chosen,  but  rather  short  sticks  of 
decaying,  charred,  or  pithy  wood,  which  cannot  easily  be  broken  or  blown 
against  the  rocks.  Holes  are  frequently  made  three  quarters  of  an  inch 
deep,  and  abandoned  because  the  spot  proves  unsuitable.  In  a  stick 
about  a  foot  and  a  half  long  and  two  or  three  inches  wide,  I  counted 
seventy-five  borings,  only  three  or  four  of  which  had  been  used  as  nests. 
The  number  of  imperfect  to  perfect  holes  must  be  as  twenty-five  to  one, 
or,  perhaps,  as  fifty  to  one.  When  a  good  piece  of  wood  is  discovered, 
the  nests  are  crowded  thickly  together ;  and  a  stick  less  than  two  inches 
in  diameter  and  five  inches  in  length  contained  thirteen  completed  nests. 
The  holes  are  pierced  at  a  slight  angle  to  the  perpendicular,  away  from 
the  insect;  they  are  straight  for  about  a  quarter  of  an  inch,  then  turn 
abruptly  and  run  horizontally  along  the  grain  for  about  an  inch.  The 
eggs  (from  ten  to  fourteen  in  number)  are  almost  always  laid  in  the  hori 
zontal  portion  of  the  nest ;  they  are  cylindrical,  tapering  toward  the  ends, 
but  not  at  all  pointed,  and  measure  from  five  to  five  and  a  half  milli 
metres  in  length,  by  one  and  one  eighth  in  breadth ;  the  ends  are  equally 
and  regularly  rounded.  They  vary  in  tint,  some  being  almost  colorless, 
and  others  of  a  faint  yellow.  After  the  eggs  have  been  carefully  packed 
away  in  the  sawdust  made  by  the  abrasion  of  the  sides  of  the  hole,  they 
are  covered  above  with  a  whitish  froth,  and  the  hole  is  sealed  up  just 
below  the  surface  of  the  wood  with  a  black  glutinous  secretion,  exces 
sively  hard,  smooth,  and  shiny,  and  the  upper  surface  slightly  concave. 
In  the  spring  the  moisture  doubtless  softens  these  coverings  so  that  the 
young  grasshoppers  can  easily  escape.  Many  old  nests  may  be  found 
uncovered  and  filled  with  the  shells  of  the  eggs,  but  none  in  which  the 
cover  is  still  retained. 

15.  Ckrysockraou  viridis  Thorn.     This  grasshopper  has  been  taken  in 
southern  New  Hampshire ;  it  has  an  extensive  range,  having  been  taken, 
according  to  Thomas,  as  far  west  as  southern  Illinois  and  Nebraska. 

1 6.  Stenobothrus  curtipennis  Scudd.     A  very  common  species  all  over 
the  state  and  in  the  valleys  of  the  White  Mountains;  it  extends  from 
Maine  to  the  Red  river  settlements  in  British  America,  and  thence  south 
ward  to  Pennsylvania,  southern  Illinois,  Colorado,  and  Wyoming.      It 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  373 

inhabits  uplands  rather  than  moist  grounds.  When  about  to  stridulate, 
these  insects  place  themselves  in  a  nearly  horizontal  position,  with  the 
head  a  little  elevated  ;  they  then  raise  both  hind  legs  at  once,  and  grate 
the  thighs  against  the  outer  surface  of  the  elytra.  The  first  one  or  two 
movements  are  frequently  noiseless  or  faint.  In  sunny  weather  the  notes 


Note  of  Stenobothrus  curtipennis. 

are  produced  at  the  rate  of  about  six  a  second,  and  are  continued  from 
one  and  a  half  to  two  and  a  half  seconds.  When  the  sky  is  overcast,  the 
movements  are  less  rapid. 

17.  StcnobotJirns  maculipennis  Scudd.  The  range  of  this  insect  is 
similar  to  that  of  the  preceding.  It  is  found  in  the  White  Mountain 
valleys  and  all  over  the  state.  Also,  westward  as  far  as  Minnesota, 
Wyoming,  and  Nebraska. 

1  8.  Stenobothrus  czqualis  Scudd.  This  insect  is  believed  by  Smith  to 
be  identical  with  the  preceding,  and  may  prove  to  be.  It  also  occurs  in 
the  White  Mountain  valleys  and  in  other  parts  of  New  Hampshire,  and 
has  been  taken  in  Maine,  Massachusetts,  New  York,  the  middle  states, 
and  Minnesota. 

19.  Tragocephala  infuscata    Harr.     A  wide  -spread   insect,  not   only 
found  in  every  part   of  the  state,  including  the  valleys    of  the   White 
Mountain  region,  and  up  at  least  to  the  sub-alpine  zone,  but  reaching 
southward  to  North  Carolina  and  Louisiana,  and  westward  to  Nebraska 
and  Colorado. 

20.  Tragocephala  sordida    Stal.     This   grasshopper   is   found   in  the 
southern  half  of  the  state,  and  extends  from  Maine,  in  the  latitude  of 
the  White  Mountains,  to    Maryland  and  Tennessee  in  the   south,    and 
Nebraska,  Iowa,  and  Minnesota  in  the  west.     It  has  also  been  taken  at 
London,  Ontario,  Canada. 

21.  Arcyptera  lineata  Scudd.     This  grasshopper  has  not  been  taken  in 
the  state,  but,  having   been  found  at  Norway,  Me.,  Williamstown   and 
Andover,  Mass.,  it  doubtless  occurs  here.     It  has  also  been  taken  in  the 
valley  of  the  Red  river  of  the  north. 

22.  Arcyptera  gracilis  Scudd.     This  insect  is  abundant  at  Jefferson 


374  PHYSICAL    GEOGRAPHY. 

and  other  parts  of  the  White  Mountains,  and  is  common  on  the  summit 
of  Graylock  in  Massachusetts ;  it  has  also  been  taken  at  Norway  and 
other  parts  of  Maine,  and  in  Minnesota,  and  is  abundant  in  the  Red  river 
settlements  of  British  America.  It  is  a  very  shy  insect,  but  stridulates 
more  loudly  than  other  Acridians ;  its  note  can  be  heard  at  a  distance  of 
fifty  feet.  It  usually  makes  four  notes,  but  the  number  is  sometimes 
greater.  The  first,  a  quarter  of  a  second  in  length,  is  duller  than  the 

Fig.  58. 


Note  of  Arcyptcra  gracilis. 

others,  and  is  followed  by  a  pause  of  a  quarter  second ;  the  other  notes 
are  of  the  same  length,  but  sharply  sounded  and  follow  each  other  rapidly. 

23.  Pezotettix  borcalis   Scudd.     This    northern    insect,  originally    de 
scribed  from  Minnesota,  the  Saskatchawan  river,  Lake  Winnipeg,  and 
the  Island  of  Anticosti,  has  since  been  mentioned  from  Speckled  moun 
tain  in  Stoneham,  Me.,  and   occurs  also   among  the  White  Mountains. 
It  is  thought  by  some  to  be  identical  with  P.frigida  of  northern  Europe. 

24.  Pezotettix  manca  Smith.     Described  from  a  single  specimen  taken 
on  Speckled  mountain,  Stoneham,  Me.;  doubtless,  therefore,  it  will  be 
found  in  the  hilly  parts  of  New  Hampshire. 

25.  Pezotettix  glacialis  Scudd.  [Plate  A,  Figs.  5,  10.]     I  have  found 
this  wingless  Acridian  most  plentifully  on  Mt.  Madison,  the  neighbor 
hood  of  the  snow-bank  in  Tuckerman's   ravine,  and  at  the  ledge,  all 
within  the  sub-alpine  zone.     In  the  latter  place  it  frequents  the  branches 
of  the  small  birch  trees.     I  am  not  aware  that  any  other  of  our  Acridians 
are  found  habitually  upon  trees.     I  have  found  this  species  on  Graylock 
(Berkshire  county),  Mass.     Mr.  Sanborn  has  taken  it  about  the  Umbagog 
lakes  in  northern  Maine,  and  Mr.  Smith  on  Speckled  mountain,  Stone- 
ham,  Me.     Of  this  latter  locality  Mr.  Smith  says, — "It  is  in  the  south 
western  part  of  Oxford  county,  and  probably  belongs  to  the  White  Moun 
tain  group.    I  am  not  aware  that  its  height  has  ever  been  determined,  but 
it  is  probably  not  much  above  two  thousand  feet.     Upon  the  upper  and 
treeless  part  of  the  mountain,  where  all  the  species  of  Pezotettix  occurred 
[see  the  two  preceding  species],  the  following  plants  were  abundant: 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  375 

Alsine  grtznlandica  Fenzl.,  Potentilla  tridentata  Ait.,  Vaccinium   Vitis- 
Idcca  Linn.,  V.  uliginosum  Linn.,  Empetrum  nigrum  Linn." 

26.  Mclanoplus  femur-rubrum  Stal.  This  species  is  wide-spread  and 
destructive ;  it  is  found  over  all  the  portions  of  the  United  States  lying 
east  of  the  Rocky  Mountains,  excepting  perhaps  those  bordering  the 
Gulf  of  Mexico.  In  New  Hampshire  it  ascends  to  the  tops  of  the  high 
est  mountains,  being  common  in  both  the  alpine  and  sub-alpine  zones. 
It  has  at  times  migrated  in  swarms  like  its  congener,  M.  spretus,  one  of 
the  most  devastating  of  all  insects.  "  The  southern  and  western  parts  of 
New  Hampshire,"  says  Dr.  Harris,  in  his  treatise  on  injurious  insects, 
"have  been  overrun  by  swarms  of  these  grasshoppers,  and  have  suffered 
more  or  less  from  their  depredations."  Dr.  True  gives  the  following 
account  of  their  ravages  in  Pownal  (Cumberland  county),  Me.,  about  half 
a  century  ago : 

During  the  haying  season  the  weather  was  dry  and  hot,  and  these  hungry  locusts 
stripped  the  leaves  from  the  clover  and  herds-grass,  leaving  nothing  but  the  naked 
stems.  In  consequence,  the  hay  crop  was  seriously  diminished  in  value.  So  ravenous 
had  they  become  that  they  would  attack  clover,  eating  it  into  shreds.  Rake  and  pitch 
fork  handles,  made  of  white  ash,  and  worn  to  a  glossy  smoothness  by  use,  would  be 
found  nibbled  over  by  them  if  left  within  their  reach. 

As  soon  as  the  hay  was  cut,  and  they  had  eaten  every  living  thing  from  the  ground, 
they  removed  to  the  adjacent  crops  of  grain,  completely  stripping  the  leaves  ;  climbing 
the  naked  stalks,  they  would  eat  off  the  stems  of  wheat  and  rye  just  below  the  head, 
and  leave  them  to  drop  to  the  ground.  I  well  remember  assisting  in  sweeping  a  large 
cord  over  the  heads  of  wheat  after  dark,  causing  the  insects  to  drop  to  the  ground, 
where  most  of  them  would  remain  during  the  night.  During  harvest  time  it  was  my 
painful  duty,  with  a  younger  brother,  to  pick  up  the  fallen  wheat  heads  for  threshing ; 
they  amounted  to  several  bushels. 

Their  next  attack  was  upon  the  Indian  corn  and  potatoes.  They  stripped  the  leaves 
and  ate  out  the  silk  from  the  corn,  so  that  it  was  rare  to  harvest  a  full  ear.  Among 
forty  or  fifty  bushels  of  corn  spread  out  in  the  corn-room,  not  an  ear  could  be  found 
not  mottled  with  detached  kernels. 

While  these  insects  were  more  than  usually  abundant  in  the  town  generally,  it  was 
in  the  field  I  have  described  that  they  appeared  in  the  greatest  intensity.  After  they 
had  stripped  everything  from  the  field,  they  began  to  emigrate  in  countless  numbers. 
They  crossed  the  highway  and  attacked  the  vegetable  garden.  I  remember  the  curious 
appearance  of  a  large,  flourishing  bed  of  red  onions,  whose  tops  they  first  literally  ate 
up,  and,  not  content  with  that,  devoured  the  interior  of  the  bulbs,  leaving  the  dry 
external  covering  in  place.  The  provident  care  of  my  mother,  who  covered  the  bed

•f 
with  chaff  from  the  stable  floor,  did  not  save  them,  while  she  was  complimented  the 

next  year  for  so  successfully  sowing  the  garden  down  to  grass.  The  leaves  were 
stripped  from  the  apple-trees.  They  entered  the  house  in  swarms,  reminding  one  of 
the  locusts  of  Egypt,  and,  as  we  walked,  they  would  rise  in  countless  numbers  and  fly 
away  in  clouds. 

As  the  nights  grew  cooler  they  collected  on  the  spruce  and  hemlock  stumps  and  log 
fences,  completely  covering  them,  eating  the  moss  and  decomposed  surface  of  the 
wood,  and  leaving  the  surface  clean  and  new.  They  would  perch  on  the  west  side  of 
a  stump,  where  they  could  feel  the  warmth  of  the  sun,  and  work  around  to  the  east 
side  in  the  morning  as  the  sun  reappeared.  The  foot-paths  in  the  fields  were  literally 
covered  with  their  excrements. 

During  the  latter  part  of  August  and  the  first  of  September,  when  the  air  was  still 
dry,  and  for  several  days  in  succession  a  high  wind  prevailed  from  the  north-west,  the 
locusts  frequently  rose  in  the  air  to  an  immense  height.  By  looking  up  at  the  sky 
in  the  middle  of  a  clear  day,  as  nearly  as  possible  in  the  direction  of  the  sun,  one  may 
descry  a  locust  at  a  great  height.  These  insects  could  thus  be  seen  in  swarms,  appear 
ing  like  so  many  thistle-blows,  as  they  expanded  their  wings  and  were  borne  along 
toward  the  sea  before  the  wind ;  myriads  of  them  were  drowned  in  Casco  bay,  and  I 
remember  hearing  that  they  frequently  dropped  on  the  decks  of  coasting  vessels. 
Cart-loads  of  dead  bodies  remained  in  the  fields,  forming  in  spots  a  tolerable  coating 
of  manure. 

27.  Mclanophis  pnnctnlatus  ( Caloptcnus  punctulatus  Uhl.).     This  insect 
having  been  taken  in  Maine  and  in  central  Vermont,  must  occur  in  parts 
of  New  Hampshire. 

28.  Mclanoplus  bivittatus  (Gryllus  bivittatus  Say).     One  may  find  this 
insect  almost  anywhere  in  New  Hampshire,  perched  on  the  huge  leaves 
of  Inula  Hclcniinn   growing  by  road -sides.     It   occurs    in   the  White 
Mountain  valleys,  and  has  a  very  wide  distribution  extending  along  the 
Atlantic  coast  from  Maine  to  Carolina  or  Georgia,  and  westward  to  the 
Rocky  Mountains,  where,  Thomas  says,  it  "is  found  east  of  the  range  from 
New  Mexico  to  Montana  [and  farther,  for  I  have  taken  it  on  Lake  Win 
nipeg,  and  Kirby  took  it  in  latitude  65°,  or  about  Fort  Simpson  in  Arctic 
America],  and  west  of  it  from  Salt  lake  north  to  the  dead  waters  of  Snake 
river ;  and,  although  it  is  not  mentioned  among  the  collections  made  in 
Washington  territory,  yet  I  am  of  the  opinion  it  will  be  found  there." 

29.  CEdipoda  Carolina  Burm.     This  grasshopper  is  found  through  all 
the  parts  of  the  state  included  in  the  Alleghanian  fauna,  but  no  farther ; 
it  is  found,  for  instance,  at  Shelburne,  on  the  Androscoggin,  but  not  in 
the  Glen,  or  the  upper  valley  of  the  Peabody.     It  is  a  wide-spread  species, 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE. 

reaching  Georgia  and  Mississippi  on  the  south,  and  extending  westward  to 
New  Mexico,  Colorado,  Nebraska,  Utah,  Wyoming,  and  even,  according 
to  Walker,  Vancouver's  island,  on  the  Pacific  coast.  It  makes  a  muffled, 
rustling  sound  with  its  wings  during  a  somewhat  sustained  flight. 

30.  Hippiscus  phcenicoptcrus   (CEdipoda  phcenicoptera   Germ.).      Ply 
mouth  is  the  only  place  in  New  Hampshire  in  which  I  have  taken  this 
grasshopper,  but  it  doubtless  occurs  in  all  the  region  south  of  the  White 
Mountains,  for  it  is  found  throughout  the  southern  part  of  New  England, 
and  as  far  south  as  Carolina,  and  even  Florida,  and,  according  to  Thomas 
and  Walker,  reaches  Colorada,  Dakota,  and  Nebraska. 

31.  Hippiscus  rugosus  (CEdipoda  rugosa  Scudd.).     This  grasshopper 
has  not  yet  been  captured  in  New  Hampshire,  but  it  undoubtedly  belongs 
to  the  fauna  of  the  state,  having  been  taken  in  Norway,  Me.,  upon  one 
side,  and  Massachusetts  on  the  other,  and  also,  according  to  Thomas,  in 
the  distant  regions  of  Nebraska,  Dakota,  and  Missouri. 

32.  Arphia  xanthoptera  ( CEdipoda  xanthoptera  Germ.).     Extends  from 
middle  New  Hampshire  to  Carolina  along  the  Atlantic  coast,  and  west 
ward  to  the  Mississippi. 

33.  Arphia  sulphured  Stal.     Although  this    insect   has   never   been 
recorded  from  New  Hampshire,  it  doubtless  inhabits  the  state,  for  it  is 
found  in  Norway,  Me.,  and  is  not  at  all  uncommon  in  Massachusetts ;  it 
is,  however,  a  southern  insect,  extending  to  Florida,  and  westward  to  Col 
orado,  Missouri,  and  Nebraska,  according  to  Thomas,  and  even,  by  Mr. 
Walker's  statement,  to  Vancouver's  island,  on  the  Pacific  coast. 

34.  Trimerotropis  aqualis  (Gryllus  czqualis  Say).     This  grasshopper 
is  found  at  Norway,  Me.,  and,  as  it  occurs  also  in  Vermont  and  Massa 
chusetts,  it  must  belong  to  the  fauna  of  New  Hampshire.     According  to 
Walker,  it  extends  south  to  Florida;  but  I  know  of  it  from  no  point 
farther  south  than  Long  island.     Westward,  I  have  taken  it  at  the  Red 
river  settlements  and  Minnesota,  and  it  also  occurs  in  Iowa,  Dakota,  and 
northern  Illinois. 

35.  Trimerotropis  verruculata  (Locusta  verruculata  Kirb.).     A  very 
abundant  species  in  the  valleys  of  the  White  Mountains,  as  well  as  all 
over  the  state ;  it  has  also  been  taken  on  the  top  of  Mts.  Tom  and  Gray- 
lock  in  Massachusetts,  in  the  northern  wilds  of  Maine,  on  the  Saguenay 
river  in  Canada,  the  region  of  the  Saskatchawan  river,  and  even  in  south-

ern  Illinois,  the  only  southern  locality  I  know ;  at  least,  Mr.  Thomas  sent 
it  to  me  from  there  :  could  he  have  received  it  from  some  other  quarter  ? 
This  insect,  like  the  preceding,  stridulates  at  will  during  flight;  the  flight 
is  well  sustained,  and  the  insect  is  capable  of  changing  its  course.  At 
each  turn  it  accompanies  the  movement  with  a  swoop-like  curve,  and

emits  a  crackling  sound.  In  verruculata  the  sound  is  like  kl  or  kla,  the 
former  at  a  distance,  the  latter  nearer  by  ;  it  is  repeated  at  the  rate  of 
about  five  per  second.  Just  before  alighting,  it  crackles  more  rapidly 
and  frequently. 

36.  Trimerotropis  maritima  Stal.     This  curious  grasshopper  is  a  good 
example  of  mimicry,  for  it  so  closely  resembles  the  color  of  the  sand  on 
a  sea-beach  that  it  is  difficult  to  see  it  when  alighted.     It  is  found  only 
in  such  localities,  and  reaches  its  northern  limits  about  the  narrow  part 
of  the  state  washed  by  the  sea.     I  have  taken  it  at  Hampton.     South 
ward  it  extends  at  least  as  far  as  New  Jersey. 

37.  Camnula  pellucida  (GEdipoda  pelhicida   Scudd.)     This  insect  is 
silent  in  flight,  and  is  a  northern  species,  swarming  in  immense  numbers 
among  the  White  Mountains  and  on  the  dry  summits  of  the  country 
south  of  it.     The  top  of  Mt.  Prospect,  near  Plymouth,  was  covered  with 
myriads  of  them  in  the  autumn  of  1873.     It  is  found,  however,  as  far 
south  as  Connecticut  and  southern  Illinois,  and  west  to  the  latter  region 
and  Lake  Superior.     It  is  very  closely  allied  to  C.  atrox  of  the  Pacific 
coast,  which  is  said  to  be  the  most  destructive  grasshopper  there,  and  to 
migrate  in  swarms  like  Melanoplus  spretus. 

38.  Tettix  granulata   Scudd.      This  is  a   northern   insect,  occurring 
throughout  the  state,  even  into  the  valleys   of  the  White  Mountains. 
Southward  it  extends  as  far  as  the  middle  states,  but  is  most  common 
farther  north  ;  it  occurs  at  Hudson's  bay  and  about  Lake  Huron,  and  as 
far  west  as  Minnesota.     Kirby  took  it  in  Arctic  America,  as  far  north 
as  lat.  65°,  probably  near  Fort  Simpson. 


THE    DISTRIBUTION    OF    INSECTS    IN    NEW    HAMPSHIRE.  379 

39.  Tcttix  ornata  Scudd.     This  more  southern  species  is  still  found  in 
New  Hampshire,  at  least  in  the  southern  portion ;  other  northern  locali 
ties  are  Norway,  Me.,  and  Royalton,  Vt.     It  extends  southward  as  far  as 
the  District  of  Columbia,  southern  Illinois,  and  eastern  Missouri. 

40.  Tettix  triangularis  Scudd.     This    species,  which   also  occurs  in 
southern  New  Hampshire,  seems  to  have  a  distribution  very  similar  to 
that  of  the  preceding,  having  also  been  taken  in  Maine,  and  extending  as 
far  south  as  the  middle  states ;  it  does  not  seem  to  have  been  noticed  far 
west,  but  has  been  taken  at  Prescott,  Canada  West. 

41.  Tettigidea  lateralis  Scudd.     Also  a  southern  species,  but  found  in 
southern  New  Hampshire,  and  in  Maine  as  far  north  as  Norway.     South 
ward,  it  extends  to  Florida,  and  westward  to  southern  Illinois  and  the 
vicinity  of  St.  Louis. 

42.  Tettigidea  polymorpha  Scudd.     The  distribution  of  this  species  is 
apparently  identical  with  that  of  the  preceding.     It  is  found  in  southern 
New  Hampshire  and  in  Maine  as  far  as  Norway,  where  it  is  said  to  be 
common ;  southward  it  is  recorded  as  far  as  Alabama,  and  west  to  Pres 
cott,  Canada  West,  southern  Illinois,  and  the  vicinity  of  St.  Louis,  Mo. 

43.  Batrachidca  cristata  Scudd.     This  species  has  apparently  a  more 
limited  range.     It  is  recorded  from  New  Hampshire,  but  from  what  por 
tion  of  it  is  unknown ;  in  Maine  it  has  been  taken  in  the  centre  of  the 
state,  and  at  Norway  "on  rocky  hills."     Southward  it  extends  to  the  mid 
dle  states,  but  is  not  mentioned  from  any  point  farther  west.

taken  in  New  Hampshire,  and  I  have  found  it  as  far  north  as  Sudbury, 
Vt.,  and  even  in  the  Red  river  settlements  in  British  America.     It  has 
also  been  taken  in  Prescott,  Canada  West,  and  extends  as  far  west  as 
Nebraska,  Kansas,  and  Iowa,  and  southward  to  Virginia,  and,  judging 
from  poor  specimens,  from  the  farther  parts  of  Texas.     It  lives  mostly 
upon  the  lower  branches  of  oaks,  or  on  young  trees  of  less  than  a  man's 
height.     The  eggs  are  dropped  loosely  upon  the  ground,  and  do  not 
hatch  until  the  succeeding  year,  sometimes  not  until  the  second  year.

as  the  "water  bug,"  has  been  taken  in  New  Hampshire;  it  undoubtedly 
reached  this  country  from  Europe. 

Doubtless  other  species  of  this  family  occur  upon  the  seaboard,  but 
none  have  been  recorded.

that  it  inhabits  New  Hampshire,  for  it  occurs  southwardly  as  far  as 
Maryland,  where  Mr.  Uhler  found  it  in  rotten  fungi,  and  even  Virginia. 
It  has  not  been  found  west  of  the  Atlantic  states.  Dohrn  considers  it 
identical  with  the  European  L.  minor.

THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE. 


BY   WILLIAM    F.    FLINT. 


BOTANISTS  divide  the  flora  of  the  United  States  into  several  nat 
ural  districts,  while  these  are  again  subdivided.  The  district  to 
which  New  Hampshire  belongs  is  the  great  Middle  and  Northern ;  but 
with  such  marked  difference,  especially  noticeable  in  our  forest  trees, 
between  the  northern  and  southern  portions  of  the  state,  as  to  be  most 
properly  considered  under  two  nearly  equal  divisions.  Including  also,  as 
it  does,  the  greater  portion  of  the  small  alpine  areas  found  within  the 
eastern  part  of  the  United  States,  and  comprising  within  its  short  range 
of  sea-coast  and  the  outlying  Isles  of  Shoals  a  small  part  of  the  Maritime 
district,  it  presents  to  us  a  more  interesting  field  for  botanical  research 
than  any  other  area  of  equal  size  east  of  the  Mississippi. 

Originally  the  state,  almost  without  exception,  was  clothed  with  a  dense 
forest.  This  forest  presented  the  same  characteristics  as  at  the  present 
day.  Its  only  change  is  that  it  has  been  greatly  restricted  in  area  by  the 
hand  of  man.  Its  leading  trees  were  pines,  spruces,  oaks,  and  hickories, 
the  beech,  chestnut,  white,  red,  and  sugar  maples,  the  butternut,  birches, 
elm,  white  and  black  ashes,  basswood,  and  poplars.  Among  shrubs  were 
the  blueberries,  the  huckleberry,  mountain  ash,  mountain  laurel,  azalea, 
alders,  and  willows ;  and,  trailing  over  rocks  and  shrubbery,  the  wild  grape, 
Virginia  creeper,  and  virgin's  bower. 

A  traveller,  passing  from  one  end  of  the  state  to  the  other,  cannot  fail 


382  PHYSICAL    GEOGRAPHY. 

to  observe  the  contrast  in  the  aspect  of  the  vegetation  of  its  northern 
and  southern  portions,  caused  by  the  different  temperature  consequent 
upon  the  difference  in  altitude.  The  flora  of  New  England  has  been 
classed  in  two  divisions,  based  upon  this  fact,  which  may  be  termed  the 
Alleghanian  and  the  Canadian,  because  they  seem  to  correspond  with 
the  faunas  of  the  same  names  described  in  the  previous  chapter.  Of 
course,  however,  no  separating  line,  or  definite  and  sudden  change,  is 
anywhere  noticed.  The  transition  is  gradual,  some  species  becoming 
scarce  and  finally  disappearing,  while  others  first  appear  in  small  num 
bers,  but  increase  as  the  traveller  advances,  and  at  length  supply  the 
place  of  the  former  as  the  prevailing  forms  of  vegetation.  Many  other 
species,  probably  one  half  in  number  of  our  whole  flora  (not  being  so 
readily  influenced  by  a  difference  of  temperature),  have  a  range  extending 
over  the  entire  state.  If  it  were  attempted  to  draw  the  line  between 
these  divisions,  on  each  side  of  which  would  of  course  be  included 
species  more  particularly  characteristic  of  the  other,  it  might  be  extended, 
approximately,  from  North  Conway  to  Lake  Winnipiseogee,  and  thence 
to  Hanover  or  vicinity.  The  transition  area  is  thus  at  an  elevation  of 
about  five  or  six  hundred  feet  above  the  sea,  corresponding  approxi 
mately  to  the  isothermal  line  of  45°  mean  annual  temperature,  or  to  20° 
during  the  winter  and  65°  during  the  summer  months. 

Among  the  species  which  are  characteristic  of  the  Alleghanian  divi 
sion,  but  find  their  northern  limit  before  reaching  this  line  or  soon  after 
it  is  crossed,  may  be  mentioned  the  chestnut,  the  white  oak,  spoonwood 
or  mountain  laurel,  and  the  frost  grape  (  Vitis  cordifolia).  The  range  of 
our  pines  and  wralnuts,  of  white  or  river  maple,  red  oak,  and  hemlock,  is 
also  mainly  southern. 

The  most  characteristic  trees  of  the  Canadian  division  are  sugar  maple, 
beech,  balsam  fir,  black  and  white  spruce,  and  arbor-vitae;  among  its 
shrubs  are  the  mountain  and  striped  maples,  and  the  mountain  ash.  Of 
these  the  white  spruce  and  arbor-vitae  have  the  most  limited  range ;  the 
former  is  abundant  about  Connecticut  lake,  but  occurs  rarely,  if  at  all, 
south  of  Colebrook;  the  latter,  often  incorrectly  called  "white  cedar," 
is  also  common  in  this  section,  extending  south  to  the  vicinity  of  the 
White  Mountains.  It  is  also  occasionally  found  in  highland  swamps 
farther  south.

THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE.  383 

A  map  has  been  prepared,  illustrating  this  distribution  in  the  case  of 
some  of  our  forest  trees.  The  lines  there  drawn  will  be  seen  to  agree 
nearly  with  contour  lines  having  the  altitudes  which  are  mentioned  in 
our  further  notice  of  these  species.  Thus  the  greater  altitude  of  the 
highlands  in  the  southern  part  of  the  state,  between  the  Merrimack  and 
Connecticut,  excludes  chestnut  and  white  oak,  and  gives  to  that  section 
a  flora  like  that  of  the  southern  part  of  the  Canadian  division. 

FOREST  TREES. 

Among  the  twenty-seven  natural  orders  which  make  up  the  greater 
part  of  the  flora  of  New  Hampshire,  we  find  the  pine  family  the  most 
important,  either  as  a  prominent  feature  of  the  landscape,  or  as  contrib 
uting  to  the  wealth  of  the  state.  First  in  this  family  is  the  white  pine, 
which  has  been  the  most  valued  of  our  forest  trees  ever  since  the  ser 
vants  of  King  George  roused  the  indignation  of  the  pioneers  by  placing 
their  "broad  arrow"  on  the  best  mast  trees  of  the  Merrimack  valley. 
When  the  country  was  covered  by  the  primeval  forest,  this  tree  filled  all 
the  river  valleys  with  a  stately  growth,  extending  along  that  of  the  Con 
necticut  to  the  northern  boundary.  At  the  present  day  this  growth  has 
nearly  disappeared  before  the  lumberman's  axe,  but  the  great  abundance 
of  saplings  in  the  southern  part  of  the  state  shows  that  this  species  is 
still  the  principal  conifer  of  that  section.  Passing  northward  into  Coos 
county,  we  find  the  white  pine  much  restricted  in  area,  occurring  mostly 
at  the  head  waters  of  the  streams,  and  mainly  confined  to  first  growth 
specimens,  saplings  being  of  rare  occurrence,  even  where  the  land  is 
allowed  to  return  to  forest  after  clearing. 

The  pitch  and  red  pines  are  much  more  limited  in  range  than  the  fore 
going.  The  pitch  pine  finds  its  most  congenial  soil  along  the  sandy 
plains  and  drift  knolls  of  the  river  valleys,  scarcely  growing  on  hills  that 
attain  much  elevation  above  the  sea  level.  It  is  found  most  abundantly 
in  the  south-eastern  part  of  the  state,  in  the  Merrimack  valley,  and 
around  Lakes  Winnipiseogee  and  Ossipee,  extending  northward  as  far  as 
North  Conway.  In  the  valley  of  the  Connecticut  it  appears  less  abun 
dantly.  The  red  pine,  often  wrongly  called  "Norway  pine,"  is  the  most 
social  of  the  pine  genus  found  with  us,  occurring  in  groups  of  from  a  few 
individuals  to  groves  containing  several  acres.  Although  much  less 


384  PHYSICAL    GEOGRAPHY. 

common,  its  range  is  nearly  the  same  as  that  of  the  pitch  pine,  probably 
attaining  a  higher  elevation  above  the  sea  level.  This  species  is  of  hand 
some  appearance  and  rapid  growth,  and  is  well  worthy  to  be  planted  for 
ornament. 

In  the  White  Mountain  region,  the  balsam  fir  and  black  spruce,  growing 
together  in  about  equal  numbers,  give  to  the  scenery  one  of  its  peculiar 
features.  The  stiff,  spiked  forms  of  the  one  are  mingled  with  the  blackish 
green  foliage  of  the  other  almost  universally  along  the  mountain  sides, 
and  are  the  last  of  arborescent  vegetation  to  yield  to  the  increased  cold 
and  fierce  winds  of  the  higher  summits.  North  of  the  mountains  these 
trees,  with  arbor-vita;,  are  the  predominant  evergreens,  mingling  with  the 
white  spruce  about  Connecticut  lake.  In  the  southern  part  of  the  state 
they  are  mostly  confined  to  the  highlands  between  the  Merrimack  and 
Connecticut,  the  black  spruce  appearing  most  abundantly. 

The  hemlock,  which  when  young  is  the  most  graceful  of  the  spruces, 
is  common  in  the  southern  part  of  the  state,  ranging  in  greatest  abun 
dance  from  around  the  base  of  the  White  Mountains  southward  along 
the  highlands,  becoming  less  common  near  the  coast.  It  has  its  northern 
limit  in  the  vicinity  of  Colebrook  and  Umbagog  lake,  reaching  an  eleva 
tion  of  about  twelve  hundred  feet  above  the  sea. 

"Our  arbor-vitae  is,"  says  Prof.  Gray,  "the  physiognomic  tree  of  our 
cold  swamps  at  the  north  and  in  Canada."  This  tree,  very  rarely  seen 
in  southern  New  Hampshire  except  when  cultivated  for  a  hedge,*  enters 
as  a  prominent  element  into  the  flora  of  Coos  county,  growing  most 
abundantly  along  the  borders  of  slow  streams  and  in  swamps,  and  varying 
from  thirty  to  fifty  feet  in  height. 

Hackmatacks,  or  tamaracks,  do  not  enter  largely  into  our  flora,  but  are 
of  very  graceful  appearance  wherever  they  are  seen.  This  species  is 
chiefly  found  in  swamps  of  small  extent,  and  ranges  along  the  highlands 
from  Massachusetts  to  north  of  the  White  Mountains.  The  red  cedar, 
or  savin,  has  the  most  limited  range  of  all  our  trees  belonging  to  this 
family,  occurring  mostly  near  the  sea-coast  in  sterile  soil.f  Juniper, 
of  the  same  family,  is  sometimes  troublesome  by  overspreading  hilly 
pastures.  The  Canadian  variety  of  the  yew  is  often  present  in  cold

land  swamps  as  an  under  shrub,  familiarly  known  by  the  name  of 
"  ground  hemlock." 

While  the  evergreens  wear  the  same  sombre  aspect  throughout  the 
year,  the  deciduous  trees  present  every  phase  of  change,  from  leafless 
branches  in  winter  to  the  delicate  green  of  spring,  the  full  leafage  of 
summer,  and  the  gorgeous  hues  of  autumn ;  so  that  to  them  are  due 
some  of  the  most  pleasing  features  of  New  Hampshire  scenery.  This 
effect  is  increased  by  their  greater  number  of  species  as  compared  with 
the  evergreens,  and  by  their  heterogeneous  mode  of  growth,  a  forest  of 
deciduous  trees  generally  containing  several  species,  growing  in  about 
equal  numbers.  In  our  forests  the  most  important  of  these  are  maples, 
beech,  birches,  chestnut,  and  oaks ;  and,  less  abundantly,  elm,  butternut, 
hickory,  ashes,  cherries,  basswood,  and  poplars. 

The  maples  are  best  represented,  all  the  species  growing  in  the  north 
ern  United  States  being  present.  First  among  these  are  our  white,  red, 
and  sugar  maples,  all  being  large  trees.  The  white  or  river  maple  is  the 
most  limited  in  range,  being  confined  to  the  intervals  of  the  principal 
streams,  and  rarely  found  away  from  them.  The  red  maple  (often 
wrongly  called  white  maple)  is  the  most  widely  spread  species,  being 
common  to  all  parts  of  the  state,  and  giving  the  brilliant  scarlet  hue  of 
our  woodlands  in  autumn.  The  rock  or  sugar  maple  is  the  largest  of  the 
genus,  and  fills  an  important  part  in  the  economy  of  the  state,  furnishing 
sugar  and  valuable  timber.  It  is  common  on  hillsides  throughout  most 
of  the  state  and  along  many  of  the  streams,  but  is  rare  toward  the  sea- 
coast. 

The  beech  and  the  sugar  maple  are  the  most  common  deciduous  trees 
of  Coos  county,  making  up  the  greater  part  of  the  "hardwood"  forests. 
Southward,  beech  is  common  to  the  highlands  only,  often  growing  with 
spruces  and  hemlocks. 

Four  species  of  birch  are  common.  Three  of  them, — the  black,  yellow, 
and  canoe  birches, — have  the  same  range  as  the  red  maple,  for  the  most 
part ;  but  the  canoe  or  paper  birch  seems  to  attain  the  highest  elevation, 
being  found  high  up  the  sides  of  the  mountains,  its  white  bark  in  striking 
contrast  with  the  dark  trunks  and  foliage  of  the  firs  and  spruces.  The 
fourth  and  smallest  of  these,  the  white  birch,  is  distinguished  for  its  light 
and  graceful  foliage,  which  renders  it  a  pleasing  feature  wherever  it  is 
VOL.  i.  5 1 


386  PHYSICAL    GEOGRAPHY. 

found.  It  is  most  abundant  in  the  south-eastern  part  of  the  state,  spring 
ing  up  along  sandy  plains  and  around  the  edges  of  woodland.  Its  growth 
is  rapid,  rising  again,  when  cut  down,  by  shoots  from  the  root.  This 
species  supplies  the  "gray  birch  hoop-poles"  used  in  the  manufacture  of 
fish  barrels. 

Five  or  six  species  of  oaks  are  found  here.  Of  these  the  red  oak  is 
the  hardiest,  but,  although  the  only  species  found  along  the  water-shed 
between  the  Merrimack  and  Connecticut,  it  does  not  extend  much  beyond 
the  White  Mountains,  having  its  upper  limit  at  about  one  thousand  feet 
above  the  sea.  The  white  and  yellow  oaks  usually  appear  together,  grow 
ing  on  the  plains  and  hillsides  along  the  rivers.  The  former  of  these, 
especially  valuable  for  the  strength  and  durability  of  its  timber,  extends 
northward  in  the  Connecticut  valley  nearly  to  the  mouth  of  the  Pas- 
sumpsic,  in  the  Merrimack  valley  to  Plymouth,  and,  in  the  eastern  part 
of  the  state,  to  the  vicinity  of  Ossipee  lake.  Its  limit  in  altitude  is  about 
five  hundred  feet  above  the  sea,  which  is  also  very  nearly  that  of  the 
frost  grape.  The  barren  or  scrub  oak  is  abundant  on  the  pine  plains  of 
the  lower  Merrimack  valley,  thence  extending  eastward  to  the  coast,  and 
to  the  sandy  plains  of  Madison  and  Conway.  The  chestnut  oak  seems 
to  be  local  in  this  state ;  at  Amherst  and  West  Ossipee  it  can  be  found 
abundantly. 

The  chestnut  is  found  in  the  same  situations  as  the  white  oak,  but  is  the 
first  to  reach  its  limit  in  altitude,  which  is  at  a  height  of  about  four  hun 
dred  feet  above  the  sea.  It  occurs  in  a  few  localities  about  Lake  Winni- 
piseogee  at  a  somewhat  greater  height,  the  neighborhood  of  the  lake 
producing  less  severity  of  temperature  than  in  the  river  valleys  at  the 
same  altitude. 

The  American  elm  attains  probably  the  largest  size  of  any  of  our 
deciduous  trees.  This  naturally  finds  its  home  in  the  alluvial  soil  of  our 
rivers.  It  has  also  been  the  most  extensively  planted  for  shade  and  orna 
ment  of  all  our  trees,  excepting  perhaps  the  sugar  maple.  Owing  to  its 
majestic  appearance,  it  is  very  conspicuous  wherever  present,  but  the 
number  growing  together  is  generally  small. 

Butternuts  also  prefer  the  borders  of  streams,  and,  in  the  valley  of  the 
Pemigewasset,  extend  northward  to  the  base  of  the  mountains.  Hicko 
ries  are  most  common  in  the  lower  Merrimack  valley,  the  shellbark 


THE   DISTRIBUTION   OF    PLANTS   IN   NEW   HAMPSHIRE.  387 

extending  northward  to  the  vicinity  of  Lake  Winnipiseogee.  Basswood 
is  found  mostly  on  highlands,  but  is  not  very  common.  The  black  cherry 
is  found  throughout  the  state,  usually  most  common  near  streams. 

Two  species  of  poplar  are  commonly  found.  The  first  is  a  small  tree, 
very  common  in  light  soil,  and  often  springing  in  great  abundance  where 
woodland  is  cleared  away.  The  other  may  be  a  large  tree,  with  dark 
colored  bark  on  the  trunk,  whence  it  is  often  called  "black  poplar."  In 
spring  the  young  leaves  are  clothed  with  white  down,  by  which  this 
species  can  then  be  distinguished  at  a  great  distance. 

SHRUBBY  PLANTS. 

Next  in  order  are  shrubs,  which,  as  an  element  of  our  flora,  are  much 
more  abundant  at  the  present  day  than  formerly,  when  the  shade  of  the 
dense  forest  restricted  them  to  the  borders  of  ponds  and  streams,  the 
thin  soil  of  rocky  hillsides,  or  the  openings  made  by  the  path  of  the 
whirlwind.  The  clearing  away  of  the  forest  gave  the  conditions  favorable 
to  the  growth  of  shrubby  vegetation.  Consequently  we  find  in  almost 
all  uncultivated  cleared  lands  a  great  variety,  the  beautiful  flowers  of 
some  being  much  admired,  while  the  fruit  of  others  is  eagerly  sought. 

Belonging  "to  the  rose  family  are  several  species  important  in  our  flora. 
In  early  spring  the  shadbush,  or  service-berry,  is  observed  almost  every 
where,  bearing  a  profusion  of  snow-white  blossoms.  This  is  followed  by 
the  pigeon  cherry,  which,  like  the  first,  often  becomes  a  small  tree.  The 
mountain  ash  flourishes  along  the  mountain  streams,  and  grows  out  of 
the  crevices  of  the  rocks  on  the  mountain  sides.  The  two  spiraeas,  or 
hardbacks,  are  very  common  by  roadsides  and  in  pastures.  The  numer 
ous  blackberries  and  raspberries  spring  up  abundantly  in  the  same 
situations,  and  in  newly  cleared  lands.  The  former  are  found  mostly  in 
the  Alleghanian  division,  being  less  common  north  of  the  White  Moun 
tains,  the  red  raspberry  there  replacing  them,  and  being  very  character 
istic  of  Coos  county.  In  this  genus  is  the  flowering  raspberry,  popularly 
called  "mulberry,"  with  broad  leaves  and  handsome  rose-like  flowers, 
often  found  in  the  Connecticut  valley. 

Growing  in  moist  soil  and  along  alluvial  banks  are  the  flowering  dog 
woods,  or  cornels,  including  several  species.  These  bear  white  flowers 
in  June,  and  clusters  of  red,  blue,  and  white  fruit  in  autumn. 


388  PHYSICAL    GEOGRAPHY. 

The  viburnums,  or  arrow-woods,  seem  as  widely  distributed  as  any  of 
our  flowering  shrubs,  and  include  the  species  familiarly  known  as  arrow- 
wood,  withe-rod,  hobble  bush,  and  cranberry  bush.  In  June,  the  pure 
white  flowers  of  the  arrow-woods  are  very  conspicuous  in  the  thickets 
bordering  meadows  and  along  streams,  while  in  the  woods  we  find  the 
hydrangea-like  blossoms  of  the  hobble  bush.  In  the  upper  Connecticut 
valley  the  cranberry  bush  is  common,  and  sometimes  cultivated,  the 
bright  red  fruit,  which  ripens  after  frosts,  being  used  as  a  substitute  for 
cranberries. 

Belonging  to  the  heath  family  we  find,  distinguished  for  beauty  and 
abundance  of  bloom,  the  kalmias,  or  American  laurels,  azalea,  rhodora, 
and  clethra,  and,  barely  entering  within  our  limits,  the  stately  Rhododen 
dron  maximum,  or  great  rose  bay,  justly  considered  one  of  the  finest  of 
the  heaths.  The  spoonwood  or  mountain  laurel  often  forms  dense  thick 
ets  in  the  swampy  woods  of  southern  New  Hampshire,  its  pink  and  white 
flowers  and  glossy  leaves  making  it  one  of  the  most  ornamental  of  our 
flowering  shrubs.  The  little  sheep  laurel,  much  detested  by  farmers, 
because  so  prone  to  overrun  pastures,  generally  appears  with  it,  bearing 
a  profusion  of  rose-red  flowers.  Along  the  edges  of  the  woodlands  and 
under  evergreens,  creeping  close  to  the  ground,  grows  the  trailing  arbu 
tus  or  Mayflower,  its  pink  and  white  fragrant  flowers  appearing  among 
the  first  in  spring.  In  cold  upland  woods  throughout  the  state,  over 
growing  old  logs  and  stumps,  is  found  the  CJiiogencs,  or  creeping  snow- 
berry,  its  snow-white  berries  half  hidden  by  the  leaves.  The  pink  azalea, 
common  to  the  swamps  of  Cheshire  county,  is  associated  in  the  minds  of 
many  with  the  day  when  our  legislature  meets,  being  popularly  called 
"election  pink."  Its  almost  flame-colored  flowers  appear  about  the  first 
of  June.  This  species  readily  bears  transplanting,  and  is  well  worthy  a 
place  among  cultivated  ornamental  shrubs.  In  moist  land  the  rhodora 
is  often  found,  rendered  very  conspicuous  by  its  purple  flowers,  which 
appear  before  the  leaves  in  early  spring.  The  Labrador  tea,  bearing  clus 
ters  of  white  flowers  in  June,  is  one  of  the  low  shrubs  of  bogs  in  Cods 
county.  The  clethra,  with  its  racemes  of  sweet-scented  white  flowers, 
appearing  in  July  and  August,  is  found  to  some  extent  in  the  swamps 
along  the  Merrimack. 

In  the  blueberry  genus  are  included  blueberries  of  several  species,  the 


THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE.  389 

huckleberry,  cranberry,  and  cowberry,  the  last  of  which  is  sub-alpine, 
and  often  called  "mountain  cranberry."  Among  the  blueberries  whose 
fruit  is  commonly  gathered  for  market,  the  dwarf,  or  Pennsylvania  blue 
berry,  has  the  most  extended  range,  being  found  far  up  the  sides  of 
mountains,  and  in  the  fields  and  pastures  everywhere.  The  swamp,  or 
high  blueberry,  is  more  limited,  being  common  to  the  swamps  and  high 
lands  southward,  rarely  appearing  as  far  north  as  Conway.  North  of  the 
mountains  the  Canadian  blueberry  is  the  representative  species.  The 
huckleberry  is  common  in  dry  soil  from  the  Merrimack  valley  eastward 
to  the  sea-coast.  The  common  cranberry  has  nearly  the  same  range  as 
the  high  blueberry,  a  smaller  fruited  species  appearing  in  Coos  county. 

Often  met  with  in  our  swamps  are  the  Canadian  holly  and  winter- 
berry,  the  latter  well  known  for  its  crimson  berries,  persistent  long  after 
the  leaves  have  fallen.  In  all  our  highland  woods  grows  the  handsome 
striped  maple,  and  along  rocky  streams  the  scarcely  less  beautiful  moun 
tain  maple.  Sumacs  delight  in  rocky  situations  on  the  southern  slopes 
of  hills,  their  purple  autumn  leaves  and  scarlet  spikes  of  fruit  being  well 
known  to  all.  Everywhere  common  is  the  alder,  not  only  along  the 
banks  of  sluggish  streams,  but  extending  along  the  marshy  hollows  of 
rough  pastures.  Seven  or  eight  species  of  willows  are  commonly  found, 
having  a  place  in  almost  every  variety  of  soil. 

HERBACEOUS  PLANTS. 

The  herbaceous  plants  occupy  the  largest  place  in  any  flora,  as  regards 
number  and  variety,  a  fact  which  is  especially  true  of  ours,  the  configura 
tion  of  the  state  giving  the  conditions  favorable  to  the  growth  of  very 
numerous  species.  Among  them  are  included  the  greater  part  of  those 
which  we  term  "wild  flowers,"  and  most  of  the  introduced  plants  which 
have  followed  the  settlement  of  the  country.  It  is  difficult  to  ascertain 
the  limits  of  many  of  our  herbaceous  plants,  as  characteristic  of  the 
Alleghanian  or  Canadian  divisions,  for  want  of  data  bearing  upon  the 
subject. 

The  sea-coast,  the  Merrimack  valley,  and  the  vicinity  of  lakes  Win- 
nipiseogee  and  Ossipee,  are  our  least  elevated  and  longest  settled  por 
tions;  consequently,  we  there  find  our  flora  richest  in  species.  The 
long  belt  of  alluvial  land  of  the  Connecticut  river  also  furnishes  a  field 


39°  PHYSICAL    GEOGRAPHY. 

favorable  to  the  growth  of  many  species  of  herbaceous  plants ;  and  to  the 
presence  of  this  river  our  Canadian  division  probably  owes  some  species 
which  would  otherwise  be  wanting.  A  marked  resemblance  is  seen  also 
between  the  herbaceous  flora  of  the  water-shed  between  the  Merrimack 
and  Connecticut,  and  that  at  the  base  of  the  White  Mountains. 

It  is  regretted  that  the  space  of  this  article  will  permit  the  mention  of 
but  few  of  the  great  variety  of  herbs  with  which  the  hand  of  the  Creator 
has  made  glad  our  fields  and  forests ;  but  the  book  of  Nature  is  ever  open, 
and  all  who  will  may  read.  The  vernal  species,  which  attract  the  atten 
tion  of  the  lover  of  nature,  are  mostly  modest  and  delicate.  Peering 
through  the  brown  carpet  of  fallen  leaves  in  our  woodlands,  we  find  in 
early  spring  the  yellow  violet,  the  dwarf  ginseng,  the  yellow  bellwort, 
trilliums,  Solomon's  seal,  the  frail  blossoms  of  the  bloodroot,  and  the 
hepatica,  with  its  downy  young  leaves  and  white  or  sky-blue  flowers. 

A  little  later  the  shining  leaves  and  yellow  bells  of  the  Clintonia  show 
themselves  beneath  the  shade  of  the  hemlocks ;  and  in  the  open  glades 
nods  the  little  wood  anemone  or  wind-flower.  In  the  crevices  of  ledges 
are  found  the  early  saxifrage  and  the  wild  columbine,  popularly  called 
"honeysuckle,"  whose  curiously  formed  flowers  swing  in  every  passing 
breeze.  The  bright  white  flower  of  the  false  mitrewort  appears  in  all 
marshy  places.  Violets  are  found  in  almost  every  kind  of  soil;  and 
nearly  every  species  of  the  Northern  states  findc  its  home  in  New  Hamp 
shire. 

In  upland  woods  we  find,  modestly  trailing  around  the  roots  of  moss- 
grown  trees,  the  fragrant  twin  flower  (Linncea  borcalis),  whose  botanical 
name  was  given  in  honor  of  Linnaeus,  who  first  discovered  it  in  Lapland, 
and  with  whom  it  was  an  especial  favorite.  Growing  in  evergreen  woods 
are  four  species  of  pyrola,  or  wintergreen,  the  prince's  pine,  Indian  pipe, 
and  pine  sap.  On  the  sandy  plains  toward  the  coast  the  wild  lupine, 
blazing  star,  and  butterfly-weed  are  not  uncommon.  In  rich,  moist  places 
we  find  the  jewel-weed,  or  wild  balsam.  Water  lilies  occur  in  all  muddy 
streams  and  ponds,  the  yellow  flowered  species  having  a  wide  range  and 
reaching  to  the  alpine  ponds  of  the  White  Mountains.  In  the  rich 
meadows  along  the  rivers  grows  the  beautiful  Canada  lily,  and  the  well 
known  red  lily  is  common  to  all  pastures.  The  cardinal  flower  rears  its 
flaming  spikes  along  the  brooksides  in  August.  Springing  up  in  great 


THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE.  3QI 

profusion  in  newly  cleared  lands  is  the  great  willow-herb,  with  very 
showy  bright  purple  flowers,  whence  it  is  often  called  "  fire-weed."  A  great 
multitude  of  asters  and  golden-rods  adorn  our  fields  in  late  summer  and 
early  fall.  Fringed  gentians  are  almost  the  last  flowers  which  appear  in 
autumn,  and  are  among  the  most  admired  of  our  wild  flowers ;  they  are 
not  everywhere  found,  but  may  be  sought  for  in  meadows  and  along 
moist  hillsides. 

The  orchis  family  attract  the  attention  as  the  most  beautiful  and  inter 
esting  endogenous  plants  in  our  flora.  Many  of  them  are  rare,  and  most 
of  them  are  limited  in  range.  Among  those  well  known  to  every  one  are 
the  fringed  orchises,  two  or  three  species  being  common  in  wet  places ; 
also,  the  little  pink  pogonia,  and,  in  woodlands,  the  round-leaved  orchis, 
with  its  shining  leaves  spread  flat  upon  the  ground.  Under  pines,  we 
find  the  handsome  stemless  ladies'  slipper ;  and,  half  hidden  in  the  grass, 
in  late  summer,  the  little  twisted  spikes  of  the  ladies'  tresses. 

The  genus  Carex,  whose  numerous  species  are  commonly  known  as 
sedges,  is  the  most  fully  represented  of  the  endogens  found  with  us, 
more  than  fifty  species  having  been  noted  in  New  Hampshire.  Although 
favorites  with  botanists,  they  are  of  little  value  to  the  farmer,  the  coarser 
species  adding  more  in  quantity  than  in  quality  to  the  hay  mown  from 
low,  wet  meadows. 

Only  two  of  the  indigenous  grasses  of  our  state  are  of  sufficient  abun 
dance  to  be  of  importance  to  agriculture.  These  are  generally  known  as 
"white-top"  (Dantlionia  spicata)  and  "blue-joint  grass"  ( Calamagrostis 
Canadensis),  the  former  being  most  abundant  in  southern  New  Hamp 
shire,  while  the  latter  is  found  throughout  the  state,  and  is  the  principal 
native  grass  of  the  upper  Connecticut  valley. 

We  find  in  the  ferns  the  most  graceful  element,  perhaps,  of  our  flora, 
and  these  are  very  well  represented,  about  forty  species  and  varieties 
being  known.  Some  of  them  are  quite  rare  or  local,  being  found  only  in 
obscure  situations,  and  likely  to  be  overlooked  except  by  the  keenest 
observer ;  but  many  of  them  abound  in  fields  and  woods,  and  are  well 
known  to  most  people.  Among  these  the  coarse  fronds  of  the  bracken, 
the  plume-like  Ostrich  fern,  and  the  more  humble  sensitive  fern  are  very 
common.  The  beech  fern  is  found  fringing  the  mossy  rocks  of  moun 
tain  brooks ;  and  in  the  shade  of  the  forest  occur  the  taller  spleenworts 


392  PHYSICAL    GEOGRAPHY. 

and  shield  ferns,  where  also,  clinging  to  moss-grown  boulders,  are  the 
handsome  evergreen  fronds  of  the  common  polypody.  The  dwarf  and 
ebony  spleenworts  and  the  frail  bladder  fern  delight  to  find  a  lodgment 
in  the  crevices  or  at  the  base  of  perpendicular  ledges. 

Our  state  may  be  called  the  home  of  the  Lycopodiums  or  club  mosses, 
popularly  known  as  "trailing  evergreen,"  all  excepting  two  of  those 
belonging  to  the  Northern  states  being  present.  They  are  found  in  deep 
woods  and  on  cold,  bleak  hillsides,  and  are  most  common  on  the  high 
lands  of  Cheshire  county  and  around  the  base  of  the  White  Mountains. 

THE  ALPINE  FLORA. 

The  wind-swept  summits  of  our  White  Mountains  are  to  the  botanist 
the  most  interesting  locality  east  of  the  Mississippi,  for  there  are  found 
the  lingering  remnants  of  a  flora  once  common  probably  to  all  New  Eng 
land,  but  which,  since  the  close  of  the  glacial  epoch,  has,  with  few  excep 
tions,  retreated  to  Arctic  America.  On  the  highest  of  these  mountains, 
only,  are  found  the  conditions  favorable  to  the  growth  of  these  arctic 
plants.  Of  these  alpine  areas,  Mt.  Washington  and  the  adjacent  peaks 
are  the  largest,  being  a  treeless  region  at  least  eight  miles  long  by  two 
miles  wide  at  its  broadest  part.  These  alpine  plants  are  of  great  hardi 
hood,  and  sometimes  bloom  amid  ice  and  snow,  as  a  Greenland  sandwort, 
found  in  bloom  on  the  summit  of  Mt.  Washington  by  Mr.  S.  A.  Nelson, 
March  n,  1871,  well  illustrates  (p.  114).  About  fifty  species  are  strictly 
alpine,  and  never  found  elsewhere  with  us.  These  are  accompanied  by 
about  as  many  other  species,  which  are  also  found  at  the  base  of  the 
mountains,  and  sometimes  throughout  the  state.  These  may  be  called 
sub-alpine,  being  found  in  the  ravines  and  on  the  lower  portions  of  the 
treeless  areas,  but  not  upon  the  higher  summits. 

The  peculiar  flora  of  these  heights,  almost  wholly  consisting  of  plants 
never  found  at  lower  elevations  south  of  arctic  latitudes,  but  identical 
with  those  found  on  Mt.  Katahdin  in  Maine,  and  the  Adirondacks  in  New 
York,  has  led  naturalists  to  inquire  how  it  is  possible  to  account  for  this 
identity  of  species  found  at  a  few  isolated  stations  in  the  midst  of  the 
temperate  zone,  with  those  of  regions  more  than  a  thousand  miles  north. 
The  conditions  of  climate  which  prevail  over  the  intervening  territory 
render  it  impossible  for  these  plants  to  maintain  their  existence,  and 


THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE.  393 

show  that  they  could  never  have  migrated  to  these  stations  under  ordi 
nary  causes.  The  science  of  geology  has  led  to  the  probable  solution  of 
this  problem.  It  has  been  found  necessary,  for  the  explanation  of  many 
phenomena  in  the  surface  geology  of  the  northern  temperate  zone,  to  sup 
pose  that  at  a  comparatively  recent  geological  period  the  climatic  condi 
tions  were  wholly  different  from  those  of  the  present  time.  The  ruins  of 
a  burned  building  do  not  tell  their  story  more  plainly  than  do  the  bould 
ers  of  our  hills  and  the  worn  and  striated  sides  of  our  mountains  prove 
the  existence  of  glaciers  and  icebergs  among  them  at  no  very  distant 
date  in  geological  history.  The  explanation  which  this  affords  of  the 
origin  of  an  arctic  flora  upon  high  mountains  in  the  temperate  zone,  has 
been  pointed  out  by  one  of  the  foremost  theorists  of  the  present  day. 
As  the  low  temperature  of  the  frigid  zone  became  gradually  extended 
over  this  whole  area,  the  forms  of  vegetation  peculiar  to  an  arctic  climate 
took  the  place  of  those  which  had  previously  existed,  while  these  receded 
to  the  south.  Again,  upon  the  gradual  return  of  a  more  genial  climate 
throughout  this  area,  the  arctic  flora  disappeared,  following  the  retreat  of 
the  causes  by  which  it  was  brought,  and  only  remaining,  with  the  rees- 
tablishment  of  warmth  and  fertility,  upon  those  higher  mountain  summits 
whose  elevation  renders  them  arctic  islands  in  the  middle  of  the  temper 
ate  zone.  He  who  ascends  to  this  altitude  has  a  similar  opportunity  for 
botanic  study  as  if  he  made  a  journey  to  the  north,  passing  first  from  the 
noble  forests,  with  which  we  are  familiar,  to  those  of  stunted  growth,  and, 
finally  leaving  them  behind  altogether,  at  length  arriving  at  the  barren 
and  bleak  regions  beneath  the  Arctic  Circle. 

In  approaching  these  mountain  summits,  one  is  first  struck  by  the 
appearance  of  the  firs  and  spruces,  which  gradually  become  more  and 
more  dwarfish,  at  length  rising  but  a  few  feet  from  the  ground,  the 
branches  spreading  out  horizontally  many  feet,  and  becoming  thickly 
interwoven.  These  present  a  comparatively  even  upper  surface,  which  is 
often  firm  enough  to  walk  upon.  At  length  these  disappear  wholly,  and 
give  place  to  the  Lapland  rhododendron,  Labrador  tea,  dwarf  birch,  and 
alpine  willows,  all  of  which,  after  rising  a  few  inches  above  the  ground, 
spread  out  over  the  surface  of  the  nearest  rock,  thereby  gaining  warmth, 
which  enables  them  to  exist  in  spite  of  tempest  and  cold.  These  in  their 
turn  give  place  to  the  Greenland  sandwort,  the  diapensia,  the  cassiope, 
VOL.  i.  52

and  others,  with  arctic  rushes,  sedges,  and  lichens,  which  flourish  on  the 
very  summits. 

INTRODUCED  PLANTS. 

As  shown  from  field-notes,  there  are  more  than  one  thousand  species  of 
plants  found  in  New  Hampshire.  Of  these  about  one  hundred  are 
"introduced,"  having  been  imported,  either  intentionally  or  otherwise, 
through  the  agency  of  man.  Some  of  them  are  indigenous  in  other 
parts  of  our  own  country,  but  the  greater  part  come  from  Europe.  Many 
of  them  have  increased  until  they  are  found  in  all  cultivated  soils,  while 
others  establish  themselves  only  locally.  In  the  former  class  are  most 
of  the  "weeds  of  cultivation,"  and  nearly  all  the  grasses  mown  for  hay. 
Most  of  these  plants,  although  so  well  established  under  the  present  con 
ditions,  would  probably  altogether  disappear  were  the  country  allowed  to 
return  again  to  its  natural  state. 

Unlike  our  indigenous  species,  these  plants  cannot  be  referred  to  any 
particular  portion  of  the  state,  because,  having  been  planted  accidentally, 
they  may  be  found  regardless  of  altitude,  &c.,  often  in  places  where  they 
would  least  be  expected.  An  instance  is  seen  in  the  garden  wormwood 
(Artemisia  Absinthium),  rarely  seen  outside  of  gardens  in  most  places, 
but  found  well  naturalized  in  Pittsburg,  our  most  northern  town,  seem 
ing  to  find  in  the  soil  derived  from  the  slaty  rocks  of  that  region  the 
conditions  exactly  suited  to  its  growth.  Instances  of  the  wide  range 
which  some  of  our  introduced  species  have  attained,  may  be  seen  in  the 
common  hemp  nettle  (Galeopsis  TetraJiit)  and  the  herds-grass  (Phi cum 
pratense).  The  former  is  common  everywhere  in  the  Merrimack  valley, 
passing  into  the  valley  of  the  Connecticut  through  Franconia  notch,  and 
reaching  northward  to  the  clearings  around  Connecticut  lake.  The 
latter,  cultivated  for  hay  throughout  the  state,  may  be  seen  in  the  lum 
ber  roads  throughout  Coos  county,  and  may  even  be  traced  up  the  car 
riage-road  on  Mt.  Washington,  far  above  the  limit  of  trees. 

The  white  willow  of  Europe  ( ' Salix  alba),  which  was  at  some  time 
introduced  for  a  shade  tree,  has  extended  itself  along  the  rivers,  evi 
dently  often  without  the  aid  of  man,  until  now  it  may  be  seen  as  far 
north  as  Stewartstown  in  the  upper  Connecticut  valley.  The  Canadian 
plum  is  much  cultivated  in  Coos  county,  and  may  often  be  seen  in  places 


THE    DISTRIBUTION    OF    PLANTS    IN    NEW    HAMPSHIRE.  395 

where  it  cannot  have  been  intentionally  planted.  The  succory  and  the 
portulaca  of  the  flower  gardens  seem  likely  to  be  added  at  some  future 
time  to  our  list  of  weeds  of  cultivation,  the  one  as  the  companion  of  the 
ox-eye  daisy,  and  the  other  with  the  common  purslane. 

CATALOGUE  OF  THE  PLANTS  OF  NEW  HAMPSHIRE. 
COMPILED  FROM  FIELD  NOTES. 

In  making  out  the  following  catalogue,  my  acknowledgments  are  due  to  Dr.  Nathan 
Barrows  of  Meriden,  Rev.  Joseph  Blake  of  Gilmanton,  Miss  Mary  Hitchcock  of 
Hanover,  Mrs.  D.  W.  Gilbert  of  Keene,  and  Warren  Upham  of  Nashua,  for  valuable 
field  notes. 

Explanation.  A  denotes  Alleghanian,  or  southern;  C,  Canadian,  or  northern; 
M,  mountain  (alpine  and  sub-alpine)  ;  and  S,  sea-coast  species.  These  letters 
italicized  indicate  that  the  species  is  strictly  limited  to  the  division  noted.  Species 
unmarked  are  likely  to  be  found  in  any  part  of  the  state,  but  many  of  them  are  of  rare 
occurrence.  Those  which  are  common  almost  everywhere,  or  in  the  division  to  which 
they  belong,  are  marked  by  a  star  (*).  Lowland  species,  which  have  extended  upwaid 
to  the  mountain  districts,  are  marked  by  a  dagger  (f).  In  some  instances  of  rare  or 
local  plants,  the  towns  in  which  they  occur  are  mentioned  below  the  name. 

The  botanic  nomenclature  is  that  of  Gray's  "Manual  of  Botany  of  the  Northern 
United  States,"  fifth  edition,  after  which  the  popular  names  are  also  given.  Italics 
denote  introduced  species.

NATURAL    HISTORY   OF   THE    DIATOMACE/E. 


BY   A.    MEAD    EDWARDS,  'M.  D. 


PREFACE. 

It  is  desirable  that  the  reader  of  the  present  brief  sketch  should,  at  the  outset,  under 
stand  that  it  is  intended  to  be  of  an  essentially  popular  character,  and  by  no  means  a 
scientific  treatise  on  the  diatomaceas.  It  has  been  prepared  in  such  a  manner  that  it 
will,  it  is  hoped,  bring  to  the  attention  of  others  besides  strictly  scientific  observers 
one  of  the  most  beautiful  groups  of  organisms  with  which  the  naturalist  is  acquainted. 
To  that  end  the  language  employed  is  as  untechnical  as  was  judged  consistent  with 
clearness  ;  and  when  it  has  been  found  necessary  to  use  technical  terms,  their  meaning 
has  been  at  the  same  time  made  plain.  This  short  preface  has  been  intended  more 
specially  for  the  scientist  into  whose  hands  this  volume  may  come,  so  that  he  may 
understand  its  aim  and  purpose,  and,  at  the  same  time,  not  judge  it  as  he  would  had 
it  made  pretence  to  a  position  among  thoroughly  scientific  works.  At  the  same  time 
it  must  be  understood  that  it  has  of  course  been  made  scientifically  correct,  so  that 
what  it  teaches  concerning  the  diatomaceaa  may  be  as  nearly  as  possible  up  to  date, 
and  consistent  with  the  latest  investigations  in  this  field  of  research. 

INTRODUCTION. 

is  a  matter  which  is  well  understood  at  the  present  day,  that  if  the 
geologist  desires  to  carry  out,  in  a  systematic  and  scientific  manner, 
his  investigations  into  the  history  of  the  globe  upon  which  he  dwells, 
he  must  earnestly  and  conscientiously  qualify  himself  for  extended  and 
searching  observations  in  many  more  branches  of  knowledge  than  his 
predecessors  of  but  a  few  years  back  considered  necessary  to  the  accom- 


NATURAL    HISTORY    OF    THE    DIATOMACE7E.  417 

plishment  of  their  labors.  To  properly  comprehend  the  structure  and 
modes  of  formation  of  strata,  be  they  made  up  of  solid  rock  or  more 
loosely  aggregated  material,  he  must  be  a  mathematician  of  no  low  order. 
To  understand  the  how,  the  why,  and  the  where  of  the  great  stone  book 
laid  open  to  his  eye,  to  read  aright  the  record  of  the  rocks,  he  must  call 
in  to  his  assistance  at  least  the  learning  of  the  physicist,  the  chemist,  and 
the  biologist,  if  he  be  not — which,  in  our  present  and  ever  growing  state 
of  knowledge  is  practically  impossible — a  physicist,  a  chemist,  and  a 
biologist  himself.  But  as  it  would  be  evidently  impossible  for  any  one 
man  to  be  thoroughly  skilled  in  all  these  branches  and  their  various 
ramifications  at  one  and  the  same  time,  the  advanced  and  advancing 
geologist  of  to-day  carries  out  the  following  special  plan,  when  engaged 
in  the  study  of  any  tract  of  country.  He  secures  the  cooperation  of  a 
number  of  specialists,  persons  who  have  devoted  their  time  and  attention 
more  particularly  to  the  study  of  distinct  sections  of  science,  so  that 
the  highest  skill  shall  investigate  for  him  the  several  parts  of  the  work, 
and  thus  individual  bricks  will  be  contributed  to  the  edifice  which 
the  geologist  desires  to  erect.  To  this  end  he  is  aided  by  at  least  a 
chemist,  who  analyzes  for  him  his  rocks,  his  metallic  ores,  his  marls, 
or  his  soils ;  a  zoologist,  who  studies  the  animals  found  in  the  section 
of  country  gone  over;  and  a  botanist,  who  turns  his  attention  to  the 
plants  discovered  in  the  district  traversed.  If  he  desires  to  carry  his 
investigations  still  further,  or  if  the  particular  section  of  country  over 
which  his  labors  extend  requires  that  he  should  do  so,  he  calls  in  to  his 
assistance  individuals  who  have  turned  their  attention  to  particular 
branches  of  chemistry,  of  zoology,  or  of  botany.  Thus,  insects  may 
abound  in  his  field  of  work,  and  the  farmers  will  like  to  know  something 
about  the  ravages  they  commit  upon  the  crops ;  or,  vegetable  diseases 
may  afflict  those  crops ;  or,  the  rocks  may  be  of  a  kind  made  use  of  in 
building ;  or,  remarkable  kinds  of  deposits,  of  great  interest  to  science  or 
of  value  in  the  arts,  may  occur.  In  all  of  these,  or  any  similar  cases,  it 
will  be  necessary  that  the  subjects  should  be  investigated  by  competent 
observers,  and  they  must  be  found,  and  their  cooperation  secured.  Where 
the  geology  alone,  as  restricted  by  the  boundaries  which  limited  it  a  few 
years  back,  is  considered,  but  few  of  these  specialists  will  be  required  to 
assist.  But,  at  the  present  day,  and,  more  particularly,  as  is  the  case 
VOL.  i.  55

with  our  state  surveys,  where  the  gentleman  who  accepts  the  position 
of  state  geologist  is  expected  to  make  his  investigations  practically  appli 
cable  and  at  an  early  date,  the  field  of  labor  is  very  much  more  extended, 
and  the  assistants  required  much  larger  in  number.  Hence  it  has  come 
to  pass  that  the  modern  geologist  recognizes  the  necessity  of  attaching 
to  his  staff  of  assistants  one  who  is  specially  skilled  in  the  use  of  the 
microscope,  an  instrument,  the  proper  employment  of  which  necessitates 
a  long  and  severe  schooling  of  the  hand  and  mind,  but  more  particularly 
the  eye  in  a  peculiar  manner  and  direction.  For  microscopy  has  become 
a  science  in  itself,  so  that,  though  the  naturalist,  the  chemist,  or  the 
physician  may  possess  and  look  through  microscopes,  yet  it  requires  one 
who  has  mastered  its  secrets,  and  has  skilled  himself  in  its  most  advanta 
geous  workings,  to  apply  it  so  as  to  obtain  the  best  results.  But,  even  in 
microscopy  as  a  branch  of  science,  there  are  specialists.  Thus,  we  find 
one  who  devotes  himself  almost  exclusively  to  perfecting  the  optical  por 
tions  of  the  instrument ;  another  will  study  its  application  to  chemistry 
and  toxicology  alone ;  another,  its  use  in  medicine,  pathology,  and  physi 
ology;  another,  its  employment  as  an  adjunct  to  geology,  and  so  on,  as 
can  be  readily  understood ;  for  science  and  knowledge  are  growing  so 
rapidly  nowadays  that  division  of  labor  becomes  as  necessary  therein  as 
it  has  been  found  to  be  in  the  mechanic  arts. 

These  few  words,  by  way  of  an  introduction,  have  been  deemed  neces 
sary,  so  that  the  general  reader,  into  whose  hands  these  volumes  may 
come,  might  understand  that  the  geological  survey  of  New  Hampshire 
has  been  the  first  of  our  state  surveys  which  has  possessed  a  special 
microscopist,  a  person  who  has  turned  his  attention  particularly  to  the 
study  of  the  application  of  that  instrument,  aided  by  other  means  of 
research,  to  the  investigation  of  geology.  It  is  true  that  similar  investi 
gations  have  been  made  to  some  extent,  by  others  as  well  as  himself,  for 
other  surveys ;  but  in  no  case  hitherto  have  special  collections  been  made 
systematically,  and  in  such  a  manner  that  any  very  valuable  results  have 
been  arrived  at,  for,  in  this  branch  of  science  as  well  as  in  others,  a  defi 
nite  end  should  be  had  in  view,  and  the  specimens  collected  and  the 
examinations  made  be  for  that  end.  It  has  remained  for  the  state  of 
New  Hampshire  to  be  the  first  to  inaugurate  a  thorough  microscopical 
survey  of  its  geology  and  assistant  branches  of  science, — paleontology, 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  419 

petrology,  and  biology;  and  it  is  to  be  hoped  that  the  results  will  be, 
therefore,  proportionally  valuable  and  interesting  to  science  at  large,  and 
conducive  to  the  welfare  more  particularly  of  the  citizens  of  that  state. 
It  has  been  considered  desirable,  and,  in  fact,  necessary  to  the  proper 
understanding  of  the  subject,  that  that  portion  of  the  work  of  the  survey 
which  comes  within  the  province  of  the  microscopist  should  be  treated  of 
under  more  than  one  head.  Thus,  at  the  present  time,  that  part  of  his 
investigations  which  has  a  particular  bearing  upon  paleontology,  or  the 
study  of  the  remains  of  organized  beings  found  stored  up  in  the  form 
of  what  are  known  as  fossils  in  the  various  strata  of  the  earth,  will  be 
treated  of,  while  micro-petrology,  or  the  examination  of  the  minute  struc 
ture  of  rock-masses  by  means  of  the  microscope,  will  be  considered  at 
another  time  and  by  another  hand,  as  the  bearings  of  the  two  branches 
are  so  very  different.  The  minor  applications  of  the  microscope  to  the 
subjects  coming  under  the  consideration  of  the  survey  will  be  gone  into 
as  opportunity  offers  and  desirability  requires.  As  it  is  to  the  study  of 
the  remains  of  the  minute  forms  of  extinct  beings  that  micro-paleon 
tology  is  at  the  present  time  particularly  devoted,  the  structure  of  more 
highly  organized  beings  not  having  been  investigated  in  this  connection 
to  any  very  great  extent,  those  smaller  organisms,  their  life,  history, 
habits,  and  relations  to  geology  and  the  useful  arts,  will  be  herein  con 
sidered  ;  and  we  shall  begin  with  a  group  of  organisms  whose  remains 
constitute,  in  some  parts  of  the  world,  strata  of  many  feet  in  thickness, 
underlying  cities,  and,  at  other  points,  make  up  the  greater  part  of  vast 
mountain  chains,  and  which  have  in  former  times  played  a  very  impor 
tant  part  in  the  history  of  our  globe.  These  are  the  Diatomaceae. 

PART    FIRST. 
A  SKETCH  OF  THE  NATURAL  HISTORY  OF  THE  DIATOMACEAE. 

As  a  large  majority  of  the  persons  into  whose  hands  the  present  vol 
ume  will  come  are  ignorant  of  the  characteristics  of  the  group  of  organ 
isms  which  it  is  intended  to  consider,  that  is  to  say,  the  Diatomacese, 
and  as  they  occupy  an  important  position  in  the  scheme  of  the  geologist, 
before  going  into  their  bearings  on  paleontology  it  has  been  thought 


42O  PHYSICAL    GEOGRAPHY. 

best,  at  the  outset,  to  devote  a  few  pages  to  a  sketch  of  their  nat 
ural  history,  presenting  familiar  and  readily  understood  descriptions  of 
their  forms  illustrated  by  figures,  their  habits,  modes  of  growth  and 
reproduction,  and  manner  of  occurrence  in  nature,  so  that  the  value  of 
a  knowledge  of  them  may  be  comprehended,  and  the  reader  be  able,  if 
he  desire  so  to  do,  to  follow  up  their  study  and  learn  where  they  are  to 
be  found,  and  how  they  may  be  collected,  prepared,  and  examined. 

It  is  a  remarkable  fact  that  these  beautiful  and  wonderful  atomies,  the 
diatomaceae,  are  so  little  known  to  biologists  in  general,  who,  we  find, 
have  neglected  in  a  remarkable  manner  to  make  themselves  acquainted 
with  the  so-called  lower  forms  of  life,  confining  to  a  great  extent  their 
investigations  to  a  study  of  the  larger  groups.  This  doubtless  has  arisen 
mainly  from  the  fact  that  they  cannot  generally  be  seen  and  much  less 
studied  by  the  unassisted  eye,  but  require,  for  the  full  elucidation  of  their 
anatomy  and  physiology,  the  most  perfect  appliances  of  modern  skill,  as 
epitomized  in  the  achromatic  compound  microscope.  Now,  however, 
that  the  microscope  is  coming  into  more  general  use  among  scientific 
observers,  it  is  to  be  hoped  that  some  obscure  points  relating  to  this 
group  of  organisms,  more  particularly  connected  with  their  mode  of 
reproduction,  as  well  as  the  subjects  of  evolution,  abiogenesis,  and  classi 
fication,  which,  it  is  considered,  may  be  more  thoroughly  studied  in 
these  apparently  simple  forms  than  in  the  more  complexly  organized 
forms  of  existence,  will  be  elucidated,  or,  at  all  events,  have  considerable 
light  thrown  upon  them.  Unfortunately,  perhaps,  the  forms  of  the  di- 
atomacese  are  so  beautiful  and  attractive,  that,  as  they  have  been  in  the 
manner  mentioned  neglected  by  accomplished  biologists,  they  have  been 
collected,  observed,  figured,  and  described  by  totally  incompetent  per 
sons,  who,  in  very  few  cases,  have  possessed  the  training  which  would 
qualify  them  for  undertaking  the  investigation  of  organisms  of  which  so 
little  is  known,  and  whose  position  in  the  plan  of  being  even  is  not 
thoroughly  established.  Hence,  a  great  deal  of  that  which  has  been  pub 
lished  on  this  subject  is  totally  useless,  if  it  be  not  in  many  cases 
absolutely  harmful,  tending  to  confuse  rather  than  simplify  matters, 
and  render  the  little  that  is  known  concerning  their  life-history  obscure. 
The  natural  consequence  has  been  that  students  of  the  diatomacea? 
have  fallen  somewhat  into  disrepute,  and,  in  some  cases,  observers  have 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  421 

been  frightened  away  from  a  field  of  inquiry  which  was  beset  with 
so  many  difficulties  at  the  outset.  Under  these  circumstances  it  is 
hoped  that  the  present  sketch  will  recommend  itself  for  perusal  to  every 
one  interested  in  natural  history,  and  at  the  same  time  introduce  to  many 
unacquainted  with  them  an  extremely  attractive  group  of  wonderfully 
constituted  and  beautifully  sculptured  beings.  Those  wishing  to  follow 
the  subject  up  more  thoroughly  will  find,  in  the  works  of  Kiitzing,  Smith, 
Rabenborst,  Ralfs,  and  others, — a  list  of  which  will  be  given  hereafter, — 
ample  opportunities  for  making  themselves  acquainted  with  what  is 
known  concerning  the  diatomaceae. 

The  Diatomaceae,  or,  as  they  have  come  to  be  familiarly  termed  by 
those  more  or  less  acquainted  with  them,  the  Diatoms,  have  been  so 
named  from  a  genus  called  Diatoma,  which  received  its  name  at  a  time 
when  it  was  considered  to  be  an  animal,  and  was  placed  in  a  group  to 
which  a  celebrated  German  naturalist,  named  Ehrenberg,  gave  the  dis 
tinctive  title  of  Polygastrica,  or,  polygastric  animalcules,  or,  minute 
animals  possessing  many  stomachs.  The  name  Diatoma  had  been 
bestowed  upon  the  organism  in  question  from  two  Greek  words,  dia, 
through,  and  tcmno,  to  cut  asunder,  on  account  of  its  appearing  as  a 
number  of  minute,  oblong  boxes,  attached,  corner  to  corner,  in  such  a 
manner  as  to  form  a  zig-zag  chain,  and  looking  as  if  the  chain  had  been 
formed  from  a  ribbon-like  band,  partially  broken  across  at  intervals. 
After  a  while,  when  it  came  to  be  known  that  the  group  to  which  the 
name  of  polygastrica  had  been  given  was  made  up  of  many  totally  dis 
tinct  groups, — some  animals,  some  plants,  and  some  neither  one  nor  the 
other,  but  merely  broken  pieces  of  animals,  plants,  or  minerals, — different 
forms  were,  one  after  the  other,  or,  in  some  cases,  many  together, 
removed  from  this  heterogeneous  assemblage.  Some,  it  was  found,  could 
be  placed  in  divisions  already  known,  but  others  had  to  be  made  into 
classes  by  themselves,  and  these  newly  constituted  groups  had  to  have 
bestowed  upon  them,  as  a  natural  consequence,  appellations  by  means 
of  which  they  might  be  distinguished  and  known.  The  Diatomacece  was 
one  of  these  apparently  natural  groups,  and  as  all  the  forms,  it  was  found, 
grew  after  a  manner  the  same  as  the  organism  upon  which  the  name  of 
Diatoma  had  been  bestowed,  that  is  to  say,  by  a  partial  or  total  splitting 
across,  the  distinctive  name  of  Diatomacca  was  given  to  them,  and  they 


422  PHYSICAL    GEOGRAPHY. 

were  erected  into  a  family  by  themselves,  and  provisionally  placed  in  the 
animal  kingdom.  Very  soon,  however,  it  was  observed  that  they  pos 
sessed  characters  inconsistent  with  animals  as  then  known,  but  more 
nearly  allied  to  plants.  For  this  reason  they  were  soon  removed  to  the 
vegetable  kingdom,  and,  after  a  time,  ranked  as  algae,  or  water-plants 
which  do  not  produce  evident  flowers.  Yet  there  have  been,  and  in  fact 
still  are,  observers  who  think  that  these  organisms  were  improperly 
removed  from  amongst  the  animals,  and  the  consequence  has  been  that, 
for  a  few  years,  they  vacillated  between  these  two  kingdoms.  By  far  the 
greater  number  of  naturalists,  however,  have  come  to  consider  them  as 
plants,  and  so  they  have  rested  up  to  a  very  late  date.  It  has  been  within 
the  last  six  or  eight  years  that  their  true  position  has  apparently  been 
determined  by  a  German  naturalist  named  Haeckel,  who  considers  that 
they  possess  characteristics  which  qualify  them  for  a  position,  along  with 
a  few  other  minute  forms  of  life,  in  a  group  separated  alike  from  animals 
and  vegetables,  and  to  which  he  has  given  the  name  of  Protista.  With 
out,  at  the  present  time  (for  it  would  be  out  of  place  in  a  publication  of 
the  character  of  the  present),  going  into  the  consideration  of  the  reasons 
which  have  influenced  the  eminent  German  naturalist  in  his  conclusions, 
suffice  it  that  the  author  of  this  sketch  coincides  with  him  in  his  opinion, 
and  considers  the  diatomaceae  to  be  neither  animals  nor  plants,  but 
Protista. 

The  diatomaceae  are  inhabitants  of  both  fresh  and  salt  water,  as  well 
as  that  which  is  brackish  by  reason  of  its  being  subjected  to  the  periodi 
cal  influx  of  the  water  of  the  ocean,  or  that  from  springs  and  streams. 
They  live  in  many  cases  attached  to  submerged  objects,  such  as  plants, 
rocks,  or  wood-work ;  but  some  species  appear  to  be  free,  and  unattached 
to  anything.  It  is,  however,  likely,  as  has  been  shown  by  the  present 
writer,  that  all  of  them  spend  a  portion  of  their  lives  attached  to  sub 
stances  below  the  surface  of  the  water,  whilst  they  have  periods  of  free 
dom  when  they  swim  about,  and  in  this  way  disseminate  the  species. 
Although  we  find  them  inhabiting  both  fresh  and  salt  water,  yet  it  would 
seem  that  there  are  certain  forms  which  will  not  thrive  in  both  of 
them.  Thus,  we  find  certain  well  marked  species  which  would  seem  to 
be  confined  to  the  ocean,  whilst  others  are  only  to  be  seen  in  running 
fresh  water,  and  still  others  exist  solely  in  quiet  lakes.  However,  so  little 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  423 

has  been  done  towards  studying  the  local  peculiarities  influencing  the 
distribution  of  these  organisms,  that  we  will  dismiss  the  subject  with  this 
brief  mention,  merely  pointing  out  that  therein  lies  a  field  for  investiga 
tion  which  will  yield  abundant  fruit  to  the  patient  and  conscientious 
student. 

They  are  to  be  found  in  all  permanent  collections  of  water,  but  have 
never  been  observed  in  pools  formed  by  the  rain  and  liable  to  be  dried 
up,  and  they  may  be  looked  for  at  all  seasons,  although,  as  might  have 
been  supposed,  they  appear  in  greatest  numbers  in  spring  and  during  the 
autumn.  The  hottest  days  of  summer,  at  least  in  such  localities  as  the 
present  writer  has  examined,  seem  to  be  unfavorable  to  their  growth 
(that  is  to  say,  in  fresh  water),  but  they  have  been  gathered  in  midwinter 
from  beneath  the  ice  in  the  Hudson  river,  New  York.  In  the  ocean  we 
find  that  season  affects  the  diatomaceae,  as  it  does  most  organisms  which, 
like  them,  live  near  tide  levels ;  that  is,  they  diminish  in  numbers  as  the 
cold  of  winter  approaches,  only  to  increase  again  in  spring. 

The  structure  of  the  diatomaceae  is  very  peculiar ;  and  although!  heir 
general  outline  can,  without  any  very  great  difficulty,  be  made  out  by 
using  a  magnifying  glass  of  moderate  power,  their  ultimate  anatomy  is 
extremely  difficult  of  elucidation,  as  will  be  exemplified  further  on.  This 
can  be  readily  understood  when  we  know  that  the  largest  of  them  are  not 
over  eight  thousandths  of  an  inch  in  diameter,  and  that  many,  and  those 
by  no  means  the  smallest,  are  only  two  ten-thousandths  of  an  inch  across. 
If  the  diatomaceae  possess  an  outer  membrane,  integument,  or,  we  might 
almost  say,  skin,  it  is  extremely  delicate,  so  much  so  that  it  has  not  with 
certainty  been  detected  as  yet,  although  one  or  two  observers  think  they 
have  seen  something  that  looks  like  such  a  seemingly  necessary  limiting 
portion  of  the  individual.  But  we  shall  see  hereafter  that  there  are 
organisms  very  closely  related  to  those  we  are  now  considering,  which 
certainly  do  not  possess  limiting  membranes,  but  whose  whole  substance 
is  homogeneous,  and  made  up  of  but  one  kind  of  substance  of  a  semi- 
gelatinous  consistence,  and  known  to  naturalists  as  protoplasm,  meaning 
the  simplest  of  all  living  matter.  It  is  likely,  then,  that  the  diatomaceae 
have  for  an  essential  base  to  their  bodies  this  protoplasm ;  and,  reasoning 
from  what  we  know  of  allied  organisms,  it  is  within  and  from,  in  part, 
the  substance  of  this  protoplasm  that  the  other  portions  of  the  individual 


424  PHYSICAL   GEOGRAPHY. 

are  elaborated,  constructed,  and  built  up.     What  appears  to  be  the  ex 
terior  membrane  of  a  diatom  is  siliceous ;  that  is  to  say,  it  is  composed 
of  the  substance  known  commonly  as  silex,  but  called  by  the  chemist 
silica.     This  is  the  same  material  as  that  which,  crystallized,  we  find  in 
rock  crystal  or   quartz,  and  which,  variously  colored,  constitutes   flint, 
agate,  jasper,  amethyst,  and  various  other  minerals  often  used  for  orna 
mental  purposes.     Of  course,  this  portion  of  the  diatom  is  very  hard, 
and  on  this  account  what  we  may  with  considerable  propriety  call  the 
skeletons    of   dead    individuals    are   used   for   the  purpose  of  polishing 
metals,  and  similar  substances,  under  the  name  of  tripoli, — although  it 
by  no  means  follows  that  all  tripoli  is  made  up  of  dead  diatom  skeletons. 
The  typical  form  of  a  mature  and  perfect  individual  diatom  is  con 
structed  after  the  following  manner :  The  outer  wall,  consisting,  as  has 
just  been  said,  of  silica,  is  formed  of  two  portions  so  fashioned  that  when 
these  are  united,  as  they  are  during  the  life  of  the  organism,  they  form 
a  little  box,  within  which  is  enclosed  the  softer  parts  which  go  to  make 
up  what  have  been  called  the  "cell  contents,"  under  the  supposition  that 
the  diatomaceae  were  "unicellular"  organisms.     Now  that  the  old  theory 
of  cell  organization  has  been  very  materially  modified,  this  appellation 
had  better  be  discarded,  as  it  has  been  used  (and  in  fact  was  constructed) 
for  the  purpose   of  describing  a  condition,  of  the   existence   of  which 
there  are  considerable  doubts.     The  whole  diatomaceaeous  individual  has 
been  called  the  frustiile,  and  under  this  designation  we  will  speak  of  it 
here.     Within  the  siliceous  wall  some  observers  have  thought  that  they 
have  detected  a  delicate  membrane  surrounding  the  rest  of  the  contents, 
but  it  is  doubtful  if  such  a  limiting  membrane  really  exists ;  and,  in  fact, 
it  is  much  more  probable  that  the  general  mass  of  the  contents  is  made 
up  of  protoplasmic  substance,  consisting,  like  such  protoplasm  usually, 
of  a  more  or  less  semi-fluid  material,  without  any  differentiation  of  its 
parts  from  the  centre  to  the  exterior.     Enclosed  within  the  mass  of  this 
clear,  colorless  protoplasm  are  seen  irregularly  formed  masses  of  a  sub 
stance  of  a  greater  consistence,  and  of  a  peculiar  light  yellowish-brown 
tint:    this  is  known   as  the   endochromc.     Sometimes  the    endochrome 
occurs  in  the  form  of  two  masses,  but  often  there  are  many  such  masses. 
In  either  case,  as  a  common  thing,  the  particles  of  endochrome  are  so 
disposed  as  to  lie  near  to  the  two  portions  of  the  siliceous  wall  which 


NATURAL   HISTORY   OF   THE   DIATOMACEyE.  425 

constitute  the  top  and  bottom  of  the  box.  Besides  this  colored  matter, 
which  gives  the  peculiar  tint  to  the  diatoms  when  seen  in  mass  at  certain 
times,  but  apparently  not  at  all  periods  of  their  existence,  we  find  the 
diatom  individuals  to  have  scattered  throughout  their  contents,  but 
always  within  the  layer  of  endochrome,  one  or  more  clear  globules  look 
ing  like  oil.  These  have  been  called  the  "oil  globules,"  and,  when  the 
diatomaceae  were  ranked  in  the  vegetable  kingdom,  were  supposed  to  be 
the  representatives  of  the  starch  found  in  the  larger  plants.  Ehrenberg, 
who  did  (and,  in  fact,  does  still)  rank  the  diatomaceae  among  animals,  con 
sidered  these  clear  spaces  to  be  stomachs,  and  fancied  he  had  been  able 
to  feed  these  organisms  on  such  colored  matter  as  indigo,  and  see  it  enter 
these  spaces.  On  account  of  their  frequently  being  present  in  numbers, 
he  constructed  for  the  diatoms  the  name  already  spoken  of, — Polygastrica, 
or  many-stomached.  There  is  no  doubt  that  diatomaceae  will  absorb 
indigo,  or  similar  material,  along  with  water,  and  thus  their  cell-contents 
may  become  tinted ;  but  such  taking  into  their  interior,  of  matter,  does 
not  prove  their  animal  nature,  as  all  the  Protista  absorb  solid  nutriment, 
and,  in  fact,  many  undoubted  plants,  under  certain  conditions,  do  the  same. 
The  typical  form  of  a  diatomaceous  individual,  then,  consists  of  a  little 
siliceous  box  with  its  cell-contents  more  or  less  colored  of  an  olive-brown 
tint.  The  variation  in  form  of  the  top  and  bottom  of  the  box,  which  are 
known  as  the  "valves,"  is  very  great,  whilst  the  band  uniting  the  valves, 
and  called  the  "connecting  membrane,"  or  "cingulum,"  remains  essen 
tially  the  same,  being  merely  a  ring,  narrower  or  wider  as  the  case  may 
be,  and  conforming  in  contour,  of  course,  to  the  valve  to  which  it  is 
attached,  and  whose  outline  it  then  typifies.  In  the  same  way,  the  sides 
of  a  trunk  form  an  oblong  ring,  and  those  of  a  pill-box  a  circular  or  oval 
loop.  Thus,  in  the  genus  Pinnularia,  the  connecting  membrane  is 
oblong,  with  rounded  ends ;  in  Coscinodiscus,  and  the  many  similar 
genera,  circular;  in  Triceratium,  triangular;  in  AmpJiitetras,  quadrangu 
lar,  and  so  on,  as  can  readily  be  understood,  and  will  be  made  more  plain 
when  the  various  forms  come  to  be  seen  in  their  integrity.  As  has  been 
said,  the  outline  of  the  valves  varies  very  greatly,  but  is,  for  the  most 
part,  constant  in  each  genus.  We  occasionally  find,  however,  that  the 
outline  of  the  valve  is  the  same  in  two  or  more  distinct  genera,  which 

are  then  separable  by  means  of  some  other  character.     The  intimate

structure  of  the  valve  itself  is  very  beautiful  and  characteristic,  but  we 
shall  be  able  here  to  consider  such  structure  in  general  terms  only,  leav 
ing  its  more  particular  description  until  we  note  the  peculiarities  of  a  few 
typical  forms,  which  will  be  described  in  detail,  and  illustrated  by  figures 
showing  their  outline  and  sculpture,  as  revealed  by  means  of  the  micro 
scope.  The  minute  sculpture  of  the  diatom  valve  is  commonly  spoken 
of  as  its  "markings,"  and  in  all  cases  they  are  generally  of  a  similar 
character  on  both  valves.  This,  however,  is  not  always  the  case,  as  we 
find  in  some  genera  which  pass  most,  if  not  all,  of  their  lives  attached 
to  objects  like  plants,  sticks,  stones,  and  the  like,  submerged  in  the  water 
(fresh,  brackish,  or  salt)  which  the  diatomaceoe  inhabit.  In  such  cases, 
as  they  are  dissimilar,  and  can  be  distinguished,  it  has  become  customary 
to  call  that  valve  which  is  next  to  the  object  upon  which  it  grows  the 
lower  valve,  and  the  opposite  one  the  upper, — and  if,  as  must  often  be  the 
case  when  the  diatom  is  fixed  to  the  under  side  of  a  plant  leaf  as  it  floats 
upon  the  surface  of  the  water,  the  position  of  the  valves  is  reversed.  In 
all  cases  the  valves  are  convex  at  the  edges,  although  they  may  be  some 
what  flattened  near  the  middle,  so  that  when  the  edges  are  in  contact 
they  enclose  the  cavity  already  spoken  of,  and  which  may  be  very  shallow 
in  proportion  to  its  width,  perfectly  spherical,  or  several  times  deeper 
than  wide. 

The  great  point  of  beauty  in  the  diatomaceae,  and  what  has  attracted 
to  them  the  attention  of  so  many  unscientific  possessors  of  microscopes, 
is  the  symmetry  and  forms  of  these  same  sculpturings  or  markings  found 
upon  the  siliceous  envelope ;  and  these  vary  in  delicacy  from  comparatively 
coarse  reticulations  to  such  extremely  minute  dots  that  no  microscope 
has  as  yet  been  constructed  which  will  show  us  what  is  their  true  char 
acter,  so  that,  as  they  lie  side  by  side  in  rows,  the  siliceous  cell-wall 
appears  to  be  marked  with  extremely  faint  lines.  But  this  is  not  all,  for 
there  are  diatoms  upon  which  even  such  faint  lines  have  not  been  seen ; 
but  we  know  that  they  must  be  fashioned  after  the  same  manner  as  their 
brothers,  and  must,  therefore,  possess  markings  of  yet  greater  fineness, 
and  which  time,  it  is  to  be  hoped,  with  the  aid  of  improved  means  of 
research,  will  reveal  to  the  inquiring  eye  of  the  future  observer.  The 
great  delicacy  of  some  of  the  markings  found  upon  diatom  cell-walls,  and 
the  consequent  difficulty  of  seeing  them,  has  led  to  great  rivalry  in 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  427 

makers  of  lenses  for  microscopes,  and  certain  species  have  been  selected 
and  accepted  as  "test  objects,"  by  means  of  which  the  power  of  lenses 
to  show  their  structure  has  been  made  evident.  But  as  this  has  become 
a  special  department  of  microscopy  we  will  pass  it  by,  at  the  present 
time,  with  this  mere  allusion.  These  beautiful  markings  are,  for  the 
most  part,  hexagonal,  that  is  to  say,  six-sided,  or,  at  least,  they  are  of 
forms  derived  from  the  hexagon,  that  being  the  form  most  economical  of 
space  under  the  circumstances.  And  it  can  be  readily  understood  how 
this  has  come  about,  if  we  consider  the  matter  after  the  following  man 
ner  :  It  is  well  known  that  matter,  by  which  is  meant  solid  or  semi-solid 
substance  of  any  kind  whatever,  if  left  to  itself  uninfluenced  by  any  out 
side  force,  as  gravity  and  the  like,  will  assume  the  globular  form.  Thus 
we  find  that  the  drop  of  water,  of  oil,  or  of  metallic  quicksilver,  is  round 
or  spherical,  or  nearly  so.  So  we  can  understand  that  the  silica  deposited 
as  skeleton  by  the  diatom  would  assume  the  spherical  form.  Likewise, 
the  minute  markings  or  granulations  made  up  by  those  siliceous  particles 
would,  in  a  like  manner,  be  at  least  spheroidal,  be  they  elevations,  as  it  is 
assumed  by  some  observers,  or  depressions,  as  is  thought  to  be  the  case 
by  the  majority  of  students.  Now,  supposing  them  to  have  a  circular 
outline  when  they  are  far  apart,  if  they  are  made  to  approach  each  other 
closer  and  closer  until  they  touch,  they,  at  last,  by  mutual  pressure,  will 
present  a  six-sided  outline.  That  such  would  be  the  case  may  be  proved, 
experimentally,  in  a  very  simple  and,  at  the  same  time,  elegant  manner. 
Let  a  mass  of  soap  and  water  be  placed  in  a  bowl,  and  a  pipe  like  a 
straw  be  thrust  down  into  it.  Then  if  air  be  blown  through  the  tube, 
keeping  the  end  opposite  to  that  placed  in  the  mouth  in  contact  with  the 
bottom  of  the  bowl,  after  a  time  the  vessel  will  become  filled  with  soap- 
bubbles  all  of  about  one  size,  and  which  we  know,  if  they  had  been 
formed  separately,  would  each  have  been  perfectly  spherical, — as,  in  fact, 
can  be  seen  on  the  top  where  those  which  are  outermost  present  an  outer 
limiting  surface  which  is  part  of  a  sphere.  But  we  see  plainly  that  these 
little  globes  have  pressed  upon  each  other  to  such  an  extent  that  they 
have  lost  their  spherical  outline,  and  have  sides  which  are  more  or  less 
plane.  If,  now,  a  plate  of  glass  be  pressed  down  upon  the  accumulation 
of  bubbles  in  the  bowl,  many  of  them  will  be  cut  in  two  in  such  a  way 
that  we  may  see  through  the  glass  that  their  section  is  an  almost  regular

hexagon.  In  fact,  such  a  collection  of  bubbles,  thus  cut  in  halves,  looks 
very  much  like  the  transparent  siliceous  membrane  of  a  diatom.  It  is 
impossible,  however,  to  give  any  idea  in  words  of  the  beauty  of  the 
diatomaceas,  and,  in  fact,  the  best  of  illustrations  affords  but  a  faint  notion 
of  them ;  they  must  be  seen  and  closely  observed  to  be  fully  appreciated. 
Their  great  interest  to  all  students  of  nature  will  perhaps  be  understood 
from  a  perusal  of  this  brief  sketch,  wherein  their  principal  points  of 
structure,  habits,  modes  of  occurrence,  and  uses,  are  set  forth  in  such  a 
way,  it  is  hoped,  as  will  be  readily  understood,  and  at  the  same  time 
prove  interesting  to  others  than  those  intending  to  be  students  of  these 
organisms. 

Having  now  arrived  at  a  pretty  clear  idea  of  the  typical  structure  of 
diatoms  in  general,  let  us  make  ourselves  more  thoroughly  acquainted 
with  some  of  the  various  forms  in  which  they  make  their  appearance. 
If  we  take,  as  a  representative  of  the  usually  free  circular  or  discoid  dia 
toms,  the  genus  Anlacodiscus,  we  find  the  valves  perfectly  round  in  out 
line,  and  usually  only  slightly  convex  near  the  margin,  the  concavity  for 
holding  the  cell-contents  being  thus  somewhat  flattened,  its  sides  being 
limited  as  usual  by  the  connecting  membrane  or  zone,  which  in  this 
genus  is  narrow.  The  structure  of  the  siliceous  material  which  goes  to 
make  up  the  valve  is  of  the  following  character:  On  the  exterior  is  a 
plate  marked  with  coarse  hexagons,  which  really  are  only  net-like ;  that 
is  to  say,  they  merely  constitute  a  hexagonal  framework  of  boxes  without 
tops  or  bottoms,  set  side  by  side,  and  arranged  more  or  less  regularly,  so 
as  to  radiate  from  the  centre  to  the  edge  of  the  valve.  The  radiant 
arrangement  of  these  coarse  markings  varies  in  regularity  in  the  differ 
ent  species  of  the  genus,  but  in  all  is  apparent.  Inside  of  this  coarsely 
marked  plate  is  another,  so  that  the  large  hexagons  have  the  character  of 
honey-comb ;  that  is  to  say,  the  sides  are  perpendicular  to  the  flat  surface 
of  the  inner  plate,  which  thus  constitutes  for  them  a  bottom.  And  this 
inner  plate  is  commonly,  although  not  always,  constructed  after  the  same 
manner  as  the  outer  one,  being  set  all  over  with  small  hexagons,  which 
are  so  small  that  as  yet  their  character  has  not  been  studied,  but  most 
likely  it  is  similar  to  the  larger  ones,  that  is  to  say,  being  honey-comb- 
like ;  but  its  hexagons  probably  have  not  in  their  turn  still  smaller  mark 
ings  within  them.  At  any  rate,  in  most  species  of  Aulacodiscus,  both 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  429 

those  with  two  sets  of  hexagonal  markings  and  those  with  only  one  set 
of  coarse  ones,  we  find  that  under,  and  often  filling  up  the  whole  bottom 
of  each  hexagon,  and  therefore  on  the  inside  of  the  inner  plate,  is  a  little 
plano-convex  lens  of  silica.  That  such  is  the  case  is  readily  proved  by 
the  images  formed  of  the  source  of  light,  as  a  candle,  by  the  little  lenses ; 
and  in  fact  it  would  doubtless  be  possible  to  measure  their  focus  by 
means  of  a  graduated  fine  adjustment  to  the  microscope,  such  as  is  found 
on  the  larger  instruments.  Sometimes  the  sides  of  the  large  hexagons 
are  not  quite  perpendicular  to  the  inner  plate,  but  approach  each  other  as 
they  descend,  so  that  the  bottom  of  the  cavity  becomes  concave ;  and,  as 
the  convexity  still  occurs  on  the  inner  surface  of  the  inner  plate,  we  have 
a  meniscus  lens  of  silica  formed, — that  is  to  say,  a  lens  which  is  still 
thickest  at  the  centre,  and  therefore  one  which  converges  light  like  the 
plano-convex  one  more  commonly  found.  The  effect  on  light  passing 
through  such  a  diatom  is  very  much  the  same  as  in  the  first  case  men 
tioned,  but  sufficiently  different  to  be  distinguished.  Though  these 
peculiarities  of  structure  can  be  made  out  by  a  careful  observer  in  Aiila- 
codiscus  and  a  few  other  genera,  on  account  of  their  size  and  coarseness 
of  structure,  yet  they  can  be  seen  only  with  difficulty  in  others,  and  in 
most  diatoms  cannot  be  shown  at  all.  And  this  can  be  readily  under 
stood  when  we  remember  that  markings  of  any  kind  upon  many  species 
can  only  indistinctly  be  seen  when  the  best  optical  appliances  for  illumi 
nation  and  the  finest  microscope  objectives  and  occulars  are  used.  In 
fact,  it  has  been  for  the  purpose  of  exhibiting  such  markings  that  objec 
tives  have  been  specially  made  and  apparatus  invented,  as  has  been 
already  said. 

The  sculpture  of  the  siliceous  cell- wall  just  described  is  not  peculiar 
to  the  Aulacodiscus,  but  is  found  in  many  other  genera.  This  particular 
genus,  however,  is  remarkable  for  possessing  what  have  been  called,  for 
want  of  a  better  name,  "feet."  These  consist  of  tubular  masses  of  silica 
projecting  outwards  from  the  cell-wall,  and  usually  placed  near  to  the 
margin  of  the  valve.  In  some  species  the  portion  from  which  the  feet 
project  is  somewhat  raised  immediately  under  each  foot,  or  in  the  form  of 
a  ridge  all  around  the  valve.  Within  this  portion  the  valve  is  either 
plane,  concave,  or  undulate,  although  the  central  portion  is  usually  some 
what  raised.  The  feet  project  outwards  at  a  greater  or  less  angle,  and 


43O  PHYSICAL    GEOGRAPHY. 

are  either  short  and  stout  or  long  and  slender,  varying  in  this  respect  in 
different  species.  They  also  vary  in  number  from  one  upwards,  the 
number  being  constant  in  some  species,  while  in  others  it  varies  very 
greatly.  Usually  the  outermost  end  is  somewhat  swelled  into  something 
like  a  knob,  and  within  this  part  the  central  canal,  running  through  the 
foot,  also  swells  into  a  spherical  cavity.  When  a  perfect  specimen  of  an 
Aulacodiscus  is  examined  on  what  is  known  as  its  "front  view,"  that  is  to 
say,  with  the  edge  of  the  valve  presented  towards  the  eye,  the  presence 
of  the  feet  makes  the  appearance  of  this  diatom  very  characteristic.  The 
description  of  this  genus  has  been  thus  full,  because  the  beautiful  com 
plexity  of  the  diatomacese  could  thus  be  made  evident,  and  many  points 
of  structure  dwelt  upon  at  the  outset.  So  when  we  come  to  describe  a 
few  of  the  other  forms  as  types,  their  resemblance  to  or  variance  from 
Aulacodiscus  will  be  noticed. 

The  genus  Coscinodiscus  has  the  same  general  characters  of  outline 
and  sculpture  of  markings  as  the  genus  just  described,  but  is  destitute  of 
"feet,"  and,  therefore,  of  the  raised  portion  upon  which  they  are  placed. 
The  two  membranes  are  present,  but  the  inner  one  is  smooth.  Both 
Aulacodiscus  and  Coscinodiscus  are  inhabitants  of  salt  water,  although 
there  is  a  minute  form,  usually  classed  as  a  Coscinodiscus  and  called 
minor,  which  has  been  seen  in  fresh  water ;  but  it  is  now  pretty  well 
ascertained  that  it  is  not  a  true  Coscinodiscus,  but  belongs  to  the  genus 
to  be  described  next. 

In  Mclosira,  the  frustules  have  a  general  resemblance  to  Coscinodiscus, 
and  are  frequently  mistaken  for  specimens  of  that  genus,  especially  when 
dead  and  detached  one  from  the  other.  Usually,  however,  the  valves  are 
so  much  more  convex  when  viewed  edgewise,  that  the  whole  frustule 
may  approach  in  form  a  sphere,  as  is  the  case  in  the  species  chosen  as 
an  illustration.  It  however  differs  widely  from  Coscinodiscus  in  having 
its  frustules  united,  by  means  of  their  valves,  into  long  chains,  which  are 
quite  flexible,  so  that  they  wave  about  in  the  moving  water.  Some 
species  have  the  valves  more  flat,  and  then  the  live  plant  looks  like  a 
number  of  pill-boxes  attached  together.  Some  species  are  peculiar  to 
fresh  water,  whilst  others  are  found  in  the  sea;  but  it  would  seem  that  a 
few  of  them  can  become  acclimated  to  and  live  in  either  kind  of  water. 

Actinoptychus,  another  beautiful  genus,  contains  several  species  which 


NATURAL    HISTORY    OF    THE    DIATOMACE7E.  43 1 

are  extremely  graceful  in  sculpture.  In  form  it  is  discoid,  on  what  is 
known  as  the  "side  view,"  but,  unlike  any  of  those  we  have  seen  so  far, 
the  surface  of  the  valve  is  divided  into  segments  which  radiate  from  the 
centre,  and  are  arranged  alternately  elevated  and  depressed,  so  that  on  a 
front  view  the  frustule  appears  undulate.  When  we  look  straight  down 
upon  the  valve,  it  has  very  much  the  appearance  of  a  wheel.  In  some 
species  the  markings  of  the  raised  segments  are  different  from  those  on 
the  sunk  portions,  while  others  have  the  markings  of  the  same  character 
all  over  the  valve.  They  are,  however,  always  of  the  same  general  char 
acter  as  those  described  as  occurring  in  Aulacodiscus.  This  is  likewise 
a  marine  genus,  and  some  of  the  most  beautiful  species  belonging  to  it 
have  been  found  as  yet  only  in  the  fossil  state. 

There  are  many  other  discoid  forms  which  we  cannot  stop  to  describe, 
but  must  pass  on  to  consider  some  other  genera. 

Nearly  allied  to  the  true  discoid  diatoms,  and  in  fact  having  a  few  cir 
cular  species,  are  two  genera  which  it  will  be  well  to  describe  here.  One 
of  them  is  called  Biddulphia,  and  is  found  only  in  salt  water,  although 
one  species  was  seen  by  the  late  Prof.  Bailey  in  the  Hudson  river  at 
West  Point,  where  the  water  is  not  all  salt ;  but,  strange  to  say,  the  tide 
reaching  up  as  far  as  this,  the  salt  water  creeps  up  under  the  fresh,  so 
that  at  this  point  salt  and  fresh  water  forms  of  vegetation  appear  along 
side  of  each  other.  Biddulphia  grows  in  chains  attached  to  submerged 
objects,  more  commonly  the  larger  plants.  It  has  valves  either  orbicular, 
elliptic,  or  more  or  less  pointed  in  two  directions,  and  approaching  in 
outline  to  the  boat-shaped  genera  to  be  presently  described.  In  fact, 
the  outline  of  the  valve  in  Biddulphia  varies  very  greatly,  as  is  seen  by 
the  figures  given.  At  two  opposite  points  on  the  valve  are  projections 
upwards  very  much  like  the  feet  of  Aulacodiscus,  and,  in  fact,  they  may 
be  considered  their  analogues.  So  when  BiddulpJiia  is  looked  at  on  a 
front  view,  it  looks  like  a  number  of  little  wool-sacks ;  and  the  species 
which  Prof.  Bailey  found  at  West  Point,  and  which  is  not  very  uncommon 
along  the  Atlantic  coast  of  the  United  States,  has  very  much  that  appear 
ance,  especially  as  the  frustules  grow  in  the  form  of  a  chain,  with  these 
projecting  portions  united,  often  alternately,  so  that  the  chain  becomes 
of  a  zigzag  form.  Sometimes  the  surface  of  the  valve  also  bears  upon 
it  certain  spines,  varying  in  number  in  different  species,  and  usually

placed  near  to  the  centre  or  at  points  midway  between  the  centre  and 
the  edge,  and  half-way  between  the  horn-like  projections. 

In  outline,  Biddulphia  passes  into  a  genus  known  as  Triceratium, 
which,  as  its  name  indicates,  is  provided  with  three  projecting  horns  or 
corners.  In  fact,  what  may  be  called  the  normal  form  of  its  valve  is 
triangular,  having  three  horn-like  projecting  portions  like  the  two  in 
Biddulphia.  But  although  the  commonest  outline  is  triangular,  we  find 
certain  species  varying  to  such  an  extent  as  to  have  examples  with  four, 
five,  and  even  six  sides, — in  this  respect  resembling  Aulacodiscus,  whose 
number  of  projections,  or  "feet,"  vary  in  the  manner  described.  And 
there  is  a  genus  called  Amphitetras,  which  apparently  only  differs  from 
Triceratium  in  the  fact  that  its  normal  form  is  with  four  corners.  In 
truth,  we  find  occasionally  specimens  of  Biddulphia  with  three  corners, 
Triceratium  with  four,  five,  six,  and  even  nine  corners,  and  AmpJiitetras 
with  five  corners,  so  it  becomes  extremely  difficult  to  draw  lines  of  dis 
tinction  between  these  three  genera.  Besides  this,  we  find  that  among 
themselves  the  species  of  Triceratium  differ  in  minor  characters ;  some 
have  the  sides  convex,  becoming  more  and  more  so,  until  at  last  we  have  a 
perfectly  circular  outline  still  retaining  the  three  projecting  horns.  Then 
we  find  them  with  sides  straight,  then  more  and  more  concave,  until  the 
valve  appears  to  be  but  three  arms  united  by  a  very  small  body.  Some 
have  undulate  sides.  The  front  view  is  as  various  as  the  side  view.  In 
some  the  processes  are  nearly  level  with  the  surface  of  the  valve,  while 
others  have  them  considerably  elevated,  and  attenuated  into  spines.  So, 
again,  in  this  beautiful  genus,  the  sculpturing  of  the  valve  is  very  various. 
We  have  coarse  hexagonal  reticulations,  with  or  without  finer  ones  within 
them,  fine  hexagonal  markings,  circular,  dot-like,  radiant  or  curved  depres 
sions,  in  some  cases  of  such  delicacy  that  high-power  glasses  are  required 
for  their  elimination.  Then,  again,  we  have  large,  heavy  bars  of  silica 
projecting  across  the  valve  in  different  directions,  merely  cutting  off  the 
corners,  or  dividing  the  central  portion  in  various  ways.  In  short,  Tricera 
tium  is  one  of  the  most  variable  as  it  is  one  of  the  most  beautiful  genera 
of  the  diatomaceae.  It  is  found  living  in  the  ocean,  growing  in  chains 
attached  to  algae  and  shells,  after  the  manner  of  Biddulphia  and  Mclosira. 
Some  of  the  most  beautiful  species  have  been  as  yet  found  only  in  the 
fossil  condition  in  certain  so-called  "infusorial"  earths. 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  433 

As  has  been  said,  the  species  of  BiddulpJiia  vary  very  greatly  among 
themselves,  until  we  have  them  approaching  the  boat-like  form  in  outline, 
and  in  this  way  they  are  connected  with  the  next  group  of  diatoms,  which 
we  now  come  to  consider.  These  are  all  more  or  less  quadrangular  in 
outline,  or,  rather,  we  might  describe  them  as  elongate,  with  more  or  less 
parallel  sides,  and  having  their  ends  acute  or  rounded.  The  genera 
belonging  to  this  group  are  very  numerous,  but  we  shall  describe  only  a 
few  of  them.  It  is  a  remarkable  fact,  that,  almost  with  the  exception  of 
some  of  the  Mclosira  and  allied  cylindrical  forms,  the  discoid,  two-,  three-, 
four-,  five-,  and  six-cornered  genera  are  confined  to  salt  water;  but  the 
boat-  and  stick-like  forms  are  found  in  both  fresh  and  salt  water,  so  that 
in  our  streams  and  ponds  we  find  the  "  naviculsef orm "  and  "bacillar" 
genera,  as  they  are  called,  almost  unmixed  with  circular  forms.  A  few 
species  of  Mclosirce,  and  an  allied  genus  called  Cyclotclla,  are  found 
occasionally  intermixed  with  the  boat-like  ones,  and  rarely  alone  in  lakes 
and  fresh-water  streams.  So  we  already  see  that,  by  examining  the 
species  of  diatoms,  we  can  say  with  considerable  certainty  whether  a 
piece  of  water  be  fresh  or  salt,  and,  if  found  in  a  fossil  condition,  whether 
the  earth,  of  which  they  make  up  a  part  or  the  whole,  was  thrown  down 
from  a  now  extinct  ocean,  lake,  or  river.  Our  knowledge  of  the  habits  of 
the  diatomacere  is  hardly  complete  enough  as  yet  for  us  to  tell  exactly  the 
character  of  lake,  river,  or  ocean  in  which  the  diatoms  grow ;  but  already 
we  have  learned  that  certain  forms  are  found  on  mountain  tops,  others  in 
swift  streams,  and  so  on. 

Taking  Pinnnlaria  as  the  first  type  of  the  naviculaeform,  or  boat- 
shaped  diatoms,  we  find  it  to  be,  of  course,  made  up  of  two  siliceous 
valves  and  a  connecting  membrane.  The  valves  are  boat-shaped  in 
outline,  sometimes  with  the  sides  parallel,  and  the  ends  pointed  or 
rounded  off.  Frequently  the  sides  are  convex  or  bowed  outwards,  bent 
inwards,  or  undulate ;  but  all  of  the  various  species,  and  they  are  very 
numerous,  preserve  the  general  characteristic  boat-like  form.  The  valves 
in  this  genus  are  commonly  very  convex,  so  that  when  looked  at  on  a 
front  view  or  endwise,  the  edges  are  distinctly  rounded  off.  Running 
down  the  middle  portion  of  the  valve  from  one  end  to  the  other  is  a 
blank  space,  which,  at  each  end  and  at  the  centre,  expands  into  round 

nodules  projecting  into  the  cavity  of  the  frustule,  as  likewise  does  the 
VOL.  i.        57 


434  PHYSICAL    GEOGRAPHY. 

blank  strip  itself.  In  fact,  this  strip,  with  its  end  and  middle  swellings, 
constitutes  a  thickened  part  of  the  valve,  and  they  have  by  some  writers 
been  called  the  "median  line,"  and  "central"  and  "terminal  nodules." 
Considerable  confusion  has  arisen  in  the  nomenclature  of  what  might  be 
called  the  osteology  of  the  diatomaceac.  This  central  thickened  band  is 
usually,  if  not  always  at  some  period  in  the  life  of  the  individual,  traversed 
by  a  canal  which  runs  the  whole  length  of  the  clear  space,  but  in  the 
thicker  ends  terminates  in  enlargements,  and  is  divided  into  two  sections 
at  the  centre  of  the  valve,  where,  likewise,  it  ends  in  two  round  cavities. 
The  end  enlargements  of  this  canal  have  also  been  called  "terminal 
nodules,"  and  the  swellings  near  the  centre  have  been  called  "  central 
nodules,"  as  well  as  the  parts  just  described.  Lately  it  has  been  proposed 
to  call  the  tube  the  "central  canal,"  and  by  this  name  we  shall  designate 
it  in  this  sketch.  At  one  period  in  the  life  of  the  diatom  it  would  seem 
that  this  canal  is  open  outwards  down  its  whole  length ;  at  least,  such  is 
the  belief  of  some  observers ;  but  the  writer  has  never  been  able  to  satisfy 
himself  that  such  is  the  case,  for  in  some  of  the  Pinnularics  he  has 
noticed  that  the  central  enlargements  of  this  canal  open,  by  means  of 
trumpet-shaped  tubes  set  at  right  angles  to  the  course  of  the  canal,  into 
the  general  cavity  of  the  frustule,  and  that  the  terminal  expansions,  in  a 
like  manner,  have  a  communication  outwards  at  the  ends  of  the  valve. 
It  is  his  opinion  that  this  canal  has  something  to  do  with  the  motion  of 
the  naviculaeform  diatoms,  which  always  sail  about  in  a  direction  parallel 
to  their  longest  axis.  The  central  canal,  when  the  diatom  valve  is  dead 
and  dry,  is  filled  with  air,  and  then, — on  account  of  the  effect  produced 
upon  the  light  as  it  is  transmitted  through  the  object  to  the  microscope, — 
appears  black,  or  nearly  so,  if  the  objective  employed  is  a  good  one,  and 
more  or  less  colored  when  an  inferior  one  is  used.  The  markings  found 
sculpturing  the  valve  of  Pinnnlaria  are  different  from  what  we  have  seen 
to  occur  in  any  of  the  genera  described  so  far.  We  find  no  large  hexa 
gons  nor  finer  ones  here,  but,  instead,  the  valve  is  marked  on  each  side  of 
the  median  blank  space  with  lines  which  indicate  elevations  in  the  form  of 
bars  or  corrugations  more  or  less  parallel  to  each  other,  and  set  at  nearly 
right  angles  to  the  central  canal.  These  bars,  or  "pinnulae,"  as  they  arc 
called,  reach  from  the  edge  of  the  valve  over  the  convex  margin,  and  up 
to  the  median  blank  space,  where  they  stop  in  rounded  off  extremities. 


NATURAL    HISTORY    OF    THE    DIATOMACEvE.  435 

There  is  a  genus  very  closely  allied  to  Pinnularia  which  has  the  same 
general  form,  except  that  in  many  of  the  species  the  sides  slope  off 
straight  towards  the  somewhat  acute  ends,  so  that  the  whole  valve  is 
quadrangular  in  form.  On  account  of  the  thickened  portion  at  the  centre 
of  the  valve  being  widened  out  so  as  to  extend  almost  or  quite  across  the 
valve  as  a  band,  and  thus,  with  the  median  blank  space,  form  a  cross,  it  has 
received  the  name  of  Stauroneis.  The  markings  on  the  valve,  however, 
are  not  those  found  on  Pinnularia,  but  consist  of  minute  depressions, 
or  dots  set  in  lines,  which  run  usually  somewhat  sloping  from  the  middle 
portion  to  the  edge.  These  rows  of  dots  are  usually  known  as  "striae," 
and  are  often  extremely  fine,  so  much  so  that  in  some  species  in  which 
they  occur  they  are  very  difficult  to  demonstrate,  and  hence  the  diatom 
becomes  a  very  good  "test-object."  In  Navicula,  the  genus  which  has 
by  far  the  largest  number  of  species,  inhabiting  fresh,  salt,  and  brackish 
water,  we  have  Stauroneis  without  the  central  cross  bar,  but  merely  the 
blank  longitudinal  space  found  in  Pinnularia. 

The  variation  in  outline  and  in  other  respects,  among  the  several  hun 
dred  species  which  have  been  grouped  together  under  the  generic  name 
of  Navicula,  is  very  great,  so  much  so,  in  fact,  that  it  would  seem  reason 
able  to  believe  that  several  genera  must  have  been  unconsciously  fused 
together.  And  such  is  the  opinion  of  the  present  writer,  in  which  he 
rather  agrees  with  some  of  the  older  writers  on  the  diatomaceae. 

There  is  a  genus  which  at  one  time  was  included  in  Navicula,  but 
which  has  of  late  years  been  separated  therefrom,  and  is  known  as  Pleu- 
rosigma.  It  looks  like  a  Navicula  which  has  been  twisted  so  as  to  bend 
the  two  opposite  sides  of  the  valve  in  different  directions.  Hence  it  has 
somewhat  the  form  of  an  S,  as  its  name  indicates.  It  has  a  central  canal 
like  the  other  naviculaeform  diatoms ;  but  the  blank  space  through  which 
it  runs  is  very  narrow.  The  central  expansion  is  generally  present ;  but 
the  terminal  swellings  are  not  so  evident.  On  this  account,  although  in 
Pinnularia  and  other  genera,  in  which  they  are  pronounced,  the  terminal 
expansions  of  the  blank,  thickened  portion  have  been  called  "terminal 
nodules;"  in  Plcurosigma,  where  they  are  not  so  apparent,  that  name 
has  been  applied  to  the  swelled  ends  of  the  central  canal, — an  example  of 
the  unscientific  manner  in  which  the  diatomaceae  have  been  treated  by 
many  who  have  written  about  them. 


436  PHYSICAL    GEOGRAPHY. 

The  markings  on  the  valves  of  Plcurosigma  are  peculiar,  and  different 
from  those  found  upon  the  other  naviculaeform  diatoms  considered.  The 
genus  can  be  and  is  usually  divided  into  two  groups,  distinguished  by  the 
character  of  the  markings.  In  the  first  group  the  valve  is  covered  with 
dots  set  all  over  the  surface  in  such  a  way  that  they  are  in  lines  at  equal 
distances  apart,  running  from  the  central  canal  to  the  edge  of  the  valve. 
But  the  next  row  starts,  as  it  were,  half  a  dot  behind  the  previous  one : 
therefore  its  dots  alternate  with  and  come  between  those  of  the  first  line, 
and  so  on,  so  that  the  dots  are  at  equal  distances  apart  all  over  the  valve, 
but,  when  traced  across  the  valve,  are  in  straight  lines,  and,  when  traced 
lengthwise  of  the  valve,  are  in  zigzag  lines.  As  these  dots  are  coarse 
and  set  far  apart  in  a  few  species,  they  can  then  be  seen  to  be  circular, 
but,  when  they  approach  each  other  closely,  they  appear  to  become,  by 
mutual  compression,  as  would  be  the  case  if  such  were  to  occur,  hexa 
gons.  In  fact,  it  has  been  one  of  the  difficult  matters  to  solve  concerning 
the  diatoms,  and  one  on  which  observers  have  differed  for  a  long  time,  as 
to  whether  the  markings  on  certain  species  of  Plcnrosigma  are  circular 
or  hexagonal.  Hence  one  species,  especially  named  Plcnrosigma  angn- 
lata,  has  been  selected  as  a  "test  object"  for  lenses  of  moderate  power. 
But  the  second  of  the  two  groups  into  which  Pleurosigma  is  divided  has 
its  markings  arranged  somewhat  differently.  In  this  group  the  dots  are 
set  in  straight  lines,  if  they  be  traced  either  across  or  lengthwise  of  the 
valve ;  that  is  to  say,  instead  of  being  alternate,  they  are  opposite  in  con 
tiguous  rows.  Among  themselves  the  different  species  of  Plcnrosigma 
vary  somewhat :  thus  in  many  the  sides  run  in  one  unbroken  line  from 
end  to  end,  being  only  swelled  out  at  the  centre.  In  P.  angnlata,  and 
still  more  so  in  P.  quadrata,  the  bowing  out  at  this  point  is  decidedly 
angular.  In  P.  Balticum,  a  species  originally  found  in  the  Baltic  sea,  and 
hence  the  name  which  was  given  to  it,  but  which  has  since  been  found 
pretty  much  all  over  the  world,  the  sides  are  straight  and  parallel  until 
near  the  ends,  when  they  are  curved  over  so  that  one  end  of  the  valve 
points  to  the  right,  while  the  other  is  turned  to  the  left.  P.  angnlata  and 
P.  quadrata  belong  to  the  group  in  which  the  dots  of  the  markings  are 
arranged  alternately,  while  P.  Balticnm  has  its  dots  set  regularly  and 
opposite  to  each  other.  P.  fasciola  differs  totally  in  outline  from  any  of 
those  described.  The  main  portion  of  its  valve  is  in  shape  like  a  Navic- 


NATURAL    HISTORY    OF    THE    DIATOMACEyE.  437 

via,  being  almost  oval,  but  pointed  at  each  end,  and  with  a  central  canal 
running  down  the  middle,  just  like  a  Navicula ;  in  fact,  it  may  be  said  to 
be  almost  shuttle-shaped ;  but  from  each  extremity  projects  a  long,  horn 
like  portion,  into  which  the  central  canal  is  continued,  and  which  is 
curved  one  to  the  right,  the  other  to  the  left,  thus  completing  the  sigmoid 
form  necessary  to  constitute  a  member  of  this  genus.  Some  species  of 
Pleurosigma  have  markings  of  such  extreme  fineness  that  it  becomes 
very  difficult  to  sec  them  unless  the  microscope  employed  be  of  the  best 
quality.  A  few  species  are  found  in  fresh  water,  but  for  the  most  part 
they  are  inhabitants  of  the  brackish  water  of  swamps  and  similar  localities. 

Some  species  of  diatoms  present  us  with  examples  of  a  peculiar  struc 
ture  not  found  in  all.  Thus,  when  we  look  at  certain  species  of  Stauro- 
ncis  from  a  front  view,  we  see  at  the  ends  and  just  below  the  terminal 
nodules,  as  a  part  of  the  valve,  and  just  where  it  joins  the  connecting 
membrane  or  zone,  a  stout  siliceous  structure  projecting  a  short  distance 
into  the  cavity  of  the  frustule  like  a  shelf,  but  more  so  at  the  ends  than 
at  the  sides,  where  it  becomes  so  shallow  as  to  be  hardly  apparent. 
When  we  look  down  upon  the  valve,  or  view  the  diatom  on  what  is  known 
as  the  side,  we  see  that  this  projecting  portion  forms  a  ring  all  around 
the  cavity,  widest  at  the  ends  and  narrowest  at  the  centre,  where  it  is 
hardly,  or  in  some  species  not  at  all,  perceptible.  This  has  been  called 
the  "septum."  In  Triccratinm,  we  find  it  appearing  only  as  slight  project 
ing  shelves  at  the  corners.  Some  genera  have  it  very  strongly  developed, 
and  projecting  very  far  into  the  cavity,  so  that  the  two  septa  divide  it 
into  three  distinct  portions.  Some  genera  have  more  than  two  septa, 
and  in  such  cases  they  are  not  fused  with  and  form  part  of  the  valves, 
but  are  attached  to  separate  rings  which  lie  between  the  edges  of  the 
valves  and  the  connecting  membrane  or  zone. 

Septa  are  very  marked  characters  in  a  genus  named  Grammatophora, 
which  is  found  in  chains  of  many  frustules,  united  corner  to  corner,  and 
attached  to  algae  in  the  ocean  on  almost  all  sea  shores.  The  valves  are 
shaped  somewhat  like  a  Pinmtlaria,  but  have  the  striae,  as  the  rows  of 
markings  have  been  called,  running  straight  across,  and  extending  quite 
up  to  the  ends.  The  septa  are  four  in  number,  and  extend  almost  across 
the  cavity  of  the  frustule,  leaving  only  a  small  opening  of  communica 
tion  at  the  centre.  Besides,  although  some  species  have  them  straight, 


43  8  PHYSICAL    GEOGRAPHY. 

in  most  they  are  undulate,  so  that  on  a  front  view  they  look  somewhat 
like  written  characters,  which  has  led  to  the  name  Grammatophora  being 
given  to  the  genus. 

Nearly  related  to  the  genus  just  mentioned  is  one  known  as  RJiabdo- 
nema.  It  likewise  is  found  growing  in  chains  attached  to  algae,  and 
similar  submerged  objects  in  the  ocean.  In  this  the  septa  are  not  con 
tinuous,  but  look  as  if  they  were  punctured  with  several  holes.  The  two 
last  mentioned  genera  are  attached  to  their  supports  by  a  small  gelati 
nous  cushion,  but  there  is  a  genus  named  Achnant/ics,  in  which  this 
cushion  is  lengthened  out  into  a  long  stalk,  and  as  it  is  attached  to  one 
of  the  corners  of  the  frustule,  the  whole  individual  looks  very  much  like 
a  flag  floating  out  straight  from  a  staff.  This  stalk  is  called  the  "stipes," 
and  is  remarkably  developed  in  other  genera.  Thus,  Gomphonema  con 
sists  of  a  number  of  wedge-shaped  frustules  attached  by  their  pointed 
ends  to  long  and  forked  stalks,  while  in  Synedra  the  stipes  has  again 
shrunk  down  to  a  cushion.  The  frustules  of  Synedra  are  like  little  sticks 
attached  to  the  cushion  by  one  end,  and  sticking  out  on  all  sides  like  the 
spines  of  a  porcupine. 

There  are  many  other  forms  which  the  various  genera  of  diatoms 
present,  but  we  have  had  space  only  to  describe  and  figure  a  few  of  them. 
The  possessor  of  a  microscope  will  soon,  if  he  searches,  come  across 
others ;  and  if  he  is  encouraged  to  ask  for  more  information  concerning 
the  beautiful  atomies  he  sees,  as  it  is  to  be  hoped  will  be  the  case,  he  will 
be  able,  in  the  works  of  W.  Smith,  Rabenhorst,  Kiitzing,  Ralfs,  and  others, 
to  find  them  more  fully  described,  and  better  and  more  thoroughly  illus 
trated.  So  to  those  works  we  must  refer  the  reader  who  desires  to  learn 
more  than  we  have  been  able  to  tell  him  in  this  little  sketch  concerning 
the  diatomaceas. 

PART    SECOND. 
MOVEMENTS  OF  THE  DIATOMACE^E. 

It  has  been  said  that  it  is  extremely  probable  that  all  species  of  dia- 
tomacere  are  at  some  period  of  their  lives  free,  while  for  a  short  period 
perhaps  for  some,  but  always  for  some  time,  they  are  fixed  or  attached  to 
some  submerged  object,  as  rocks,  plants,  woodwork,  or  similar  substances. 
This  opinion  is  not  held  by  all  observers ;  so  much  so  that  many, — and 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  439 

W.  Smith,  the  author  of  the  Synopsis  of  the  British  Diatomaceoe,  among 
that  number, — have  classified  them  in  such  a  way  as  to  constitute  two 
great  groups,  namely,  those  which  are  free,  and  those  which  occur 
attached.  It  would  seem  most  natural  that  those  forms  which  commonly 
present  themselves  attached  should  become  free  at  some  period  of  their 
existence  for  the  purpose  of  disseminating  the  species,  for  we  do  not  find 
that  the  diatomaceas  produce  seed  which  may  be  wafted  about  by  the 
motion  of  the  water,  or  young  which  are  specially  characterized  by  pos 
sessing  organs  of  motion,  so  that  this  phenomenon  may  be  accomplished. 
However  this  may  be,  it  is  a  fact  that  many  of  them  possess  peculiar 
movements,  produced  by  and  inherent  in  themselves,  and  which  have 
from  the  earliest  times,  when  they  were  first  observed,  attracted  the 
attention  and  aroused  the  wonder  of  possessors  of  microscopes.  And 
when  these  seeming  sentient  movements  are  watched  by  means  of  the 
magnifying  glass,  it  is  not  to  be  wondered  at  that  many  observers  have 
been  disposed  to  class  them  among  animals  possessing  complicated  organs 
of  locomotion,  digestion,  and  reproduction,  if  not  reasoning  powers  to 
guide  and  direct  those  organs.  And  this  power  of  active  movement  is 
not  confined  to  those  forms  alone  which  are  usually  seen  free,  for  many 
of  the  fixed  forms,  if  detached  from  their  support,  will  immediately  take 
upon  themselves  motions  precisely  similar  to  those  of  their  normally 
free  brethren. 

The  extreme  liveliness  of  some  of  the  diatomaceae  has  been  considered 
by  many  as  proof  of  their  animal  nature ;  but  when  we  know  that  the 
seeds  of  many  large  and  acknowledged  plants  growing  in  water,  namely, 
the  algae,  are  even  more  active  in  their  motions  than  our  little  friends,  and, 
as  in  the  case  of  those  plants,  this  motion  is  evidently  for  disseminating 
the  species,  so  we  may  naturally  believe  that  some  similar  provision  is 
made  for  the  wide  spreading  of  the  diatom aceae.  If  we  watch,  by  means 
of  a  good  microscope,  an  individual  belonging  to  the  genus  Navicula,  in 
which  the  form,  when  viewed  in  the  direction  which  is  usually  presented 
to  the  eye,  is  that  of  a  double-prowed  boat,  something  like  an  Indian 
canoe,  we  find  that  it  moves  after  the  manner  of  a  boat,  but  with  either 
prow  forward,  as  happens  to  be  most  convenient,  apparently,  for,  after 
moving  in  one  direction  for  a  few  seconds  or  minutes,  it  will  immediately 
return  upon  its  course,  now  propelling  the  other  forward.  And  although 


44O  PHYSICAL    GEOGRAPHY. 

in  a  few  species,  and  those  seemingly  the  larger,  the  motion  is  a  steady 
progressive  one,  yet  it  is  by  far  commoner  to  find  that  it  is  unsteady  and 
trembling,  as  if  it  were  the  tottering  steps  of  the  infant,  or  of  extreme 
old  age.  Navicula  is  one  of  those  genera  which  are  usually  classed 
among  the  free  forms,  and  in  them  all,  with  perhaps  one  or  two  excep 
tions,  when  they  have  any  progressive  motion,  it  is  that  which  we  have 
described.  There  is  a  genus  which  has  very  much  the  form  of  a  horse 
saddle  with  the  two  flexures,  and  known  as  Campy lo discus,  in  which  "the 
motion  never  proceeds  farther  than  a  languid  roll  from  one  side  to  the 
other." 

As  has  been  remarked,  the  earlier  observers  of  these  atomies,  being 
insufficiently  informed  on  the  subject  of  the  economy  of  the  vegetable 
kingdom,  considered  the  possession  of  the  power  of  spontaneous  motion 
by  any  being  indisputable  evidence  of  its  animal  nature ;  and,  on  this 
foundation,  it  became  easy  to  rear  up  a  mass  of  proofs  that  the  diatoma- 
ceas  were  certainly  animals.  The  space  within  the  two-valved  shell,  like 
an  oyster  or  clam,  was  the  animal  matter  furnished  with  special  organs, 
if  not  with  muscles,  by  means  of  which  the  movements  were  accom 
plished.  Of  course,  the  many  clear  vacuole-like-looking  spots  of  oily 
matter  were  the  stomachs,  and,  with  the  imperfect  microscopes  of  the 
time,  observers  were  (they  thought)  able  to  see  the  protrusion  of  a  "foot" 
like  that  upon  which  the  snail  travels,  through  the  central  portion,  which 
looked  to  them  like  a  round  opening,  but  which  we  now  know  to  be  a 
thickened  portion  of  the  shell.  A  late  observer  has  asserted  that  he  has 
seen,  along  the  so-called  "median  line,"  an  appearance  indicating  the  pro 
trusion  of  an  organ  or  series  of  organs  of  some  kind ;  but  as  others, 
equally  competent  microscopists,  have  not  been  able  to  satisfy  themselves 
that  there  are  such  organs,  this  gentleman's  assertion  can  hardly  be  said 
to  be  proven.  There  are  still  a  few  microscopists  who  hold  to  the  belief 
in  the  animal  nature  of  the  diatomacere,  although  by  far  the  majority 
rank  them  as  plants.  One  gentleman  in  England  says  that  he  has 
seen  (and,  what  is  more,  figures)  the  cilia,  or  hairs,  which  move  about 
like  arms,  and  by  means  of  which  these  creatures  change  their  place. 
Unfortunately,  he  first  takes  the  animal  nature  of  the  diatomaccrc  for 
granted,  and  then  attempts  to  prove  the  existence  of  the  cilia  as  organs 
of  locomotion. 


NATURAL    HISTORY    OF    THE    DIATOMACEyE.  44! 

It  will  be  naturally  supposed,  from  what  has  been  said  on  the  subject, 
that  the  mode  in  which  the  motion  is  caused  is  not  decidedly  known ; 
but  however  that  may  be,  it  is  a  remarkable  characteristic  of  these  crea 
tures,  and,  although  in  most  species  it  is  regular  and  uniform,  in  some  it 
takes  place  as  a  series  of  jerks.  It  would  seem  that  it  could  hardly  be 
called  a  voluntary  motion,  or,  at  least,  that  if  it  be  so,  the  faculty  govern 
ing  and  directing  it  within  the  creature  is  of  a  low  order,  or  one  which 
responds  to  stimulus  in  a  very  sluggish  manner ;  for  if  an  obstacle  of  any 
kind  occur  in  the  path  of  a  moving  diatom,  like  a  Navicula,  it  is  not 
avoided ;  but,  on  the  contrary,  if  it  be  small  enough,  it  is  thrust  aside ; 
or,  if  it  be  too  large,  the  diatom  is  arrested  in  its  career  for  a  certain 
length  of  time,  or  turned  aside  in  its  course.  If  it  be  stopped,  it  is  a 
remarkable  fact,  noted  by  English  observers,  that  the  diatom  waits  exactly 
the  length  of  time  it  would  have  taken  for  it  to  perfect  its  forward  pro 
gression  to  the  greatest  extent,  when  it  returns  on  its  path  again.  In 
many  species,  however,  the  motion  is  not  so  regular  as  this,  and  the  little 
creature  goes  tottering  along  its  way.  It  has  been  remarked  by  one 
author  that  "the  movements  of  the  diatomaceae  appear  rapid  and  viva 
cious  under  the  microscope;  but  it  must  be  remembered  that  the  high 
powers  usually  employed  in  the  observation  of  these  minute  organisms 
magnify  their  motions  as  well  as  their  bulk."  Using  a  seconds  watch, 
and  timing  several  species  exactly,  it  has  been  found  that  one  of  the 
most  rapid,  known  as  Bacillaria  paradoxa,  took  a  whole  second  to  move 
over  one  two-hundreth  of  an  inch ;  and  that  one  of  the  slowest,  named 
Pinnularia  radiosa,  in  the  same  space  of  time  only  travelled  one  thirty- 
four-hundredth  of  an  inch ; — so  that  the  quickest  would  take  three  min 
utes  to  travel  an  inch,  while  its  slowest  relative  would  require  a  full  hour 
to  perform  the  same  feat.  But  although  a  few  observations  of  this  kind 
have  been  made,  we  have  by  no  means  arrived  at  a  knowledge  of  the 
rate  of  movement  of  these  atomies,  for  it  varies  under  different  circum 
stances,  as  apparent  condition  of  health  and  surroundings.  Heat  appears 
to  accelerate  as  cold  retards  it ;  and  yet  I  have  seen  Bacillaria  paradoxa 
very  lively  when  taken  from  beneath  the  ice  on  a  cold  winter's  day.  It 
is  a  curious  fact,  that  often,  as  we  watch  a  diatom  sailing  across  the  field 
of  the  microscope,  it  comes  in  contact  with  an  obstacle,  as  a  grain  of 
sand.  If  it  cannot  move  it,  or  pass  under  it,  or,  by  a  little  shifting,  around

it,  it  waits  exactly  the  length  of  time  it  would  have  taken  for  it  to  perfect 
its  forward  progression,  when  it  returns  on  its  path  again.  But  this  takes 
place  only  with  such  species  as  have  a  regular  backward  and  forward  mo 
tion  ;  most  of  them  are  extremely  erratic  in  their  ways.  As  an  illustration 
of  the  regularity  of  movement  of  the  diatomaceas,  let  us  consider  one  of 
those  species  just  mentioned,  namely,  Bacillaria  paradoxa.  This  crea 
ture  has  a  motion  of  its  own,  which  is  so  peculiar,  and  at  the  same  time 
so  incomprehensible  in  its  mode  of  accomplishment,  that  it  well  deserves 
a  more  particular  description.  This  species  is  somewhat  of  the  form  of 
a  straight  ruler,  when  we  consider  the  single  individual,  or,  at  least,  it 
looks  very  much  of  that  form,  as  commonly  seen.  But  a  careful  exami 
nation  shows  it  to  be  made  up  of  two  long  and  narrow  boat-shaped  valves, 
united  together  so  that  the  keels  project  outwards  opposite  to  each  other, 
and  enclose  within  their  united  bodies  the  general  cavity  of  the  frustule. 
When  in  a  living  state,  the  compound  individual,  or  colony,  whichever 
we  may  choose  to  consider  it,  consists  of  a  number,  more  or  less  great, 
of  these  double  boat-shaped  frustules,  united  one  to  the  other  at  their 
keeled  sides ;  but  the  mode  of  union  is  entirely  unknown,  and,  from  the 
extreme  freedom  of  motion  which  each  frustule  of  the  colony  enjoys,  it 
is  hard  to  imagine  what  its  character  is.  Thus  united,  they  form  a  fila 
ment  which  is  generally  found  floating  freely  in  the  water  of  brackish 
ditches  within  reach  of  the  influence  of  the  sea.  But  I  have  seen  it  in 
perfectly  fresh  water,  far  up  the  Hudson  river  in  New  York  state. 

The  movement  has  been  well  described  by  an  English  observer,  Mr. 
Thwaites,  and  I  cannot  do  better  than  quote  his  words.  He  says, — 

When  the  filaments  have  been  detached  from  the  plants  to  which  they  adhere,  a 
remarkable  motion  is  seen  to  commence  in  them.  The  first  indication  of  this  consists 
in  a  slight  movement  of  a  terminal  frustule,  which  begins  to  slide  lengthwise  over  its 
contiguous  frustule  ;  the  second  acts  simultaneously  in  a  similar  manner  with  regard  to 
the  third,  and  so  on,  throughout  the  whole  filament ;  the  same  action  having  been  going 
on  at  the  same  time  at  both  ends  of  the  filament,  but  in  opposite  directions.  The  cen 
tral  frustule  thus  appears  to  remain  stationary,  or  nearly  so,  while  each  of  the  others 
has  moved  with  a  rapidity  increasing  with  its  distance  from  the  centre,  its  own  rate  of 
movement  having  been  increased  by  the  addition  of  that  of  the  independent  move 
ment  of  each  frustule  between  it  and  the  central  one.  This  lateral  elongation  of  the 
filament  continues  until  the  point  of  contact  between  the  contiguous  frustules  is 
reduced  to  a  very  small  portion  of  their  length,  when  the  filament  is  again  contracted 


NATURAL    HISTORY   OF   THE   DIATOMACE^E.  443 

by  the  frustules  sliding  back  again,  as  it  were,  over  each  other ;  and  this  changed 
direction  of  movement  proceeding,  the  filament  is  again  drawn  out  until  the  frustules 
are  again  only  slightly  in  contact.  The  direction  of  the  movement  is  again  reversed, 
and  continues  to  operate  in  opposite  directions,  the  time  occupied  in  passing  from  the 
elongation  in  one  direction  to  the  opposite  being  generally  about  forty-five  seconds. 
If  a  filament  while  in  motion  be  forcibly  divided,  the  uninjured  frustules  of  each  por 
tion  continue  to  move  as  before,  proving  that  the  filament  is  a  compound  structure, 
notwithstanding  that  its  frustules  move  in  unison.  When  the  filament  is  elongated  to 
its  utmost  extent,  it  is  extremely  rigid,  and  requires  some  comparatively  considerable 
force  to  bend  it,  the  whole  filament  moving  out  of  the  way  of  any  obstacle  rather  than 
bending  or  separating  at  the  joints. 

This  is  not  always  the  case,  as  I  have  myself  frequently  observed,  as 
the  filament  often  becomes  bent  by  the  force  of  its  own  motion.  And 
there  is  one  other  fact  which  seems  to  have  escaped  the  notice  of  Mr. 
Thwaites,  and  which  adds  considerably  to  the  interest  of  an  exhibition 
of  this  plant  while  in  motion.  After  the  extended  frustules  have  returned 
to  their  normal  position  in  the  filament,  so  as  to  form  a  ribbon-like  com 
bination  again,  and  just  at  the  time  when  they  are  about  to  start  on  their 
way  in  the  opposite  direction,  there  seems  as  if  a  considerable  amount  of 
force  were  necessary  to  get  them  started  past  this  point,  for  this  force  is 
very  apt  to  dislodge  the  whole  filament  and  swing  it  entirely  round,  so 
that  that  end  which  was,  we  may  say,  pointing  towards  the  right  hand, 
now  points  to  the  left.  The  consequence  is,  that  now,  when  the  frustules 
proceed  on  their  path  towards  the  opposite  side  of  the  filament  from 
which  they  projected  previously,  they,  in  reality,  extend  towards  the  same 
side  of  the  microscope  as  they  returned  from.  This  motion  often  contin 
ues  to  be  exerted,  so  that  the  whole  filament  is  periodically  swung  around 
on  its  centre  as  the  frustules  return  to  their  places,  and  become  again 
parallel  one  to  the  other.  Often  and  often  have  I  spent  hours  looking  at 
this  marvel  of  nature ;  the  motion  without  apparent  cause  or  mode,  an 
invisible  joint,  which,  as  a  friend  of  mine  (an  engineer)  once  remarked, 
would  be  a  fortune  to  any  one  who  would  discover  it,  for  here  we  have 
several  sticks  forming  the  bundle,  moving  over  each  other  without  sep 
arating,  and  yet  the  use  of  the  highest  powers  of  the  microscope  has 
failed  to  detect  the  means  of  their  union  into  one  mass,  or  composite 
group,  of  individuals.  The  more  often  I  watch  Bacillcria  pamdoxa,  the 
more  it  puzzles  me.  Not  long  since  I  saw  one  specimen  (of  course,  I 


444  PHYSICAL   GEOGRAPHY. 

mean  one  bundle  of  individuals)  slide  out  to  its  utmost  limit  across  the 
field  of  view,  and  then,  becoming  entangled  with  others,  which  likewise 
were  made  up  of  many  individuals,  some  eight  or  ten  of  its  frustules 
were  twisted  around,  almost  off  from  the  rest,  so  as  to  lie  at  right  angles 
to  them ;  and  when  the  group  containing  the  largest  number  of  frustules 
receded  to  their  former  position,  which  they  soon  did,  the  eight  or  ten 
seeming,  by  the  act  of  twisting,  to  lose  their  power  of  motion  among 
themselves  for  the  time  being,  were  dragged  along  in  a  helpless  condi 
tion,  and  twisted  completely  around  one  revolution,  so  as  thereafter  to 
fall  back  again  into  their  places,  when  all  went  on  again  as  usual, — that 
is  to  say,  the  regular  motion  of  all  the  frustules  over  each  other  succeeded. 
Now  what  kind  of  a  joint  can  it  be  that  permits  of  such  eccentric  move 
ment  ?  The  motion  of  all  diatoms  is  accelerated  by  a  moderate  heat,  so 
that  specimens  gathered  during  the  winter  months,  and  remaining  either 
quiescent,  or  only  exhibiting  very  slight  motion  when  viewed  by  means 
of  the  magnifying  glass  of  the  microscope,  may  be  made  to  move  vigor 
ously  by  the  cautious  application  of  warmth,  as  by  placing  them  in  a 
warm  room,  or  by  holding  the  glass  slide,  upon  which  they  are,  upon  the 
palm  of  the  hand  for  a  short  time. 

PART    THIRD. 
MODE  OF  GROWTH  OF  THE  DIATOMACE^E. 

When  we  speak  of  the  growth  of  the  Diatomacese,  it  must  not  be 
confounded  with  the  reproduction  of  the  organisms,  although  modern 
physiologists  are  coming  to  understand  that  growth  or  increase  in  vol 
ume,  and  reproduction  or  increase  in  number,  are  very  nearly  related,  if 
they  be  not  but  modification,  in  degree  and  in  direction,  of  a  force  acting 
within  and  essential  to  the  existence  of  living  beings. 

We  have  seen  what  the  structure  of  the  outer  coat  or  siliceous  skeleton 
of  the  diatomaceae  is.  Let  us  now,  before  asking  how  they  grow  or 
increase  in  dimensions,  learn  what  is  known  with  regard  to  their  internal 
economy,  that  is  to  say,  the  anatomy  of  their  softer  parts.  Unfortu 
nately,  on  this  point  our  knowledge  is  extremely  unsatisfactory,  and  it 
even  appears,  as  has  been  already  hinted,  that  the  result  of  modern 
investigations  would  be  to  upset  a  great  deal  of  what  we  have  up  to  a 
late  date  considered  as  settled  in  connection  with  this  point. 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  44$ 

Immediately  within  the  siliceous  skeleton  of  a  diatom  is  supposed  by 
many  to  be  a  membrane  or  skin  which  bounds  and  limits  the  soft  parts  of 
the  organism ;  and  it  is  this  membrane,  say  those  who  believe  in  its  exist 
ence,  which  secretes  or  forms  the  wonderfully  sculptured  epiderm  we 
have  been  considering.  Some  observers  think  that  there  is  also  an  out 
side  membrane,  and  that  it  is  in  it  that  the  silica  accumulates.  But  as 
many  good  observers  have  been  able  to  see  neither  of  these  membranes 
in  the  living  diatom,  and  as  even  the  believers  in  their  existence  acknowl 
edge  that  they  are  extremely  difficult  of  exhibition,  most  likely  the  fact  is 
that  the  real  individual  matter  of  the  diatom  is  a  mass  of  structureless 
protoplasm,  which  deposits  near  its  outer  portion  the  silica  it  has  absorbed 
from  the  surrounding  water.  Within  the  protoplasmic  mass  is  the  endo- 
chrome  or  colored  matter  we  have  already  spoken  of,  and  which  is  most 
commonly  disposed  in  two  portions  contiguous  to  the  two  valves.  In  the 
clear  central  portion  there  is  often  to  be  seen  a  little  sac  or  vesicle,  which 
is  quite  transparent,  except  at  one  part,  where  a  minute  dot  is  seen.  This 
vesicle  is  considered  to  be  the  "nucleus"  of  the  diatom,  while  the  dot  is 
the  "nucleolus,"  both  of  these  things  being  required  in  a  cell  constituted 
under  the  type  established  by  a  German  observer  named  Schwann.  But 
now  that  Schwann's  typical  cell,  consisting  of  a  "cell  wall"  containing 
"cell  contents,"  wherein  are  found  a  "nucleus"  and  often  one  "nucleolus" 
or  several  "nucleoli,"  is  known  to  exist  rarely,  we  are  not  surprised  if 
we  do  not  find  all  of  these  parts  present  in  a  diatom.  And  now  that 
we  understand  the  internal  anotomy  of  the  diatom,  without  taking  into 
consideration  disputed  minutiae  of  structure,  we  can  see  how  the  indi 
vidual  grows. 

Schwann  has  shown  us  what  he  considers  cell  growth  to  be,  and  it 
is  what  is  known  as  "cell  subdivision."  That  is  to  say,  the  cell  itself  is 
stable  as  to  size,  but  increase  of  volume  occurs  by  its  dividing  into  two, 
and  these  two  into  four,  and  so  on,  so  that  if  the  resulting  cells  remain 
united  to  each  other  there  will  eventuate  a  true  increase  in  bulk,  and 
eventually  a  large  organism  like  a  tree  or  a  man  may  be  formed.  But 
such  is  not  the  way  that  the  diatom  grows,  for  it  is  not  a  polycellular,  but 
a  unicellular  organism.  There  is  a  large  group  of  very  simple  plants, 
even  more  simple  in  structure  than  the  diatomaceae,  for  they  have  no 
elaborately  sculptured  siliceous  cell-wall,  which  are  known  as  ProtopJiytes, 


446  PHYSICAL    GEOGRAPHY. 

and  in  the  life  history  of  one  of  these  we  shall  be  able  to  study  the  sim 
plest  expression  of  cell  growth.  Dr.  Carpenter,  whose  valuable  treatise 
on  the  microscope  is  to  be  recommended  to  all  intending  to  use  that 
instrument,  has  epitomized  what  is  known  on  this  subject  so  well  that  I 
cannot  do  better  than  to  give  it  in  his  own  words.  He  says, — 

The  life-history  of  one  of  these  unicellular  plants,  in  its  most  simple  form,  can 
scarcely  be  better  exemplified  than  in  the  Palmoglcca  macrococca  (Kiitzing) — one  of 
those  humble  kinds  of  vegetation  which  spreads  itself  as  a  green  slime  over  damp 
stones,  walls,  &c.  When  this  slime  is  examined  with  the  microscope,  it  is  found  to 
consist  of  a  multitude  of  green  cells  (Fig.  A) ,  each  surrounded  by  a  gelatinous  envel 
ope  ;  the  cell,  which  does  not  seem  to  have  any  distinct  membranous  wall,  is  filled 
with  granular  particles  of  a  green  color ;  and  a  nucleus,  or  more  solid  aggregation, 
which  appears  to  be  the  centre  of  the  vital  activity  of  the  cell,  may  sometimes  be 
distinguished  through  the  midst  of  these.  When  treated  with  tincture  of  iodine, 
however,  the  green  contents  of  the  cell  are  turned  to  a  brownish  hue,  and  a  dark 
brown  nucleus  is  distinctly  shown.  Other  cells  are  seen  (B),  which  are  considerably 
elongated,  some  of  them  beginning  to  present  a  sort  of  hour-glass  contraction  across 
the  middle ;  in  these  is  commencing  that  curious  multiplication  by  binary  subdivison, 
which  is  the  ordinary  mode  of  increase  throughout  the  vegetable  kingdom ;  and  when 
a  cell  in  this  condition  is  treated  with  tincture  of  iodine,  the  nucleus  is  seen  to  be 
undergoing  the  like  elongation  and  constriction.  A  more  advanced  state  of  the  pro 
cess  of  subdivision  is  seen  at  C,  in  which  the  constriction  has  proceeded  to  the  extent 
of  completely  cutting  off  the  two  halves  of  the  cell,  as  well  as  of  the  nucleus  (I),  from 
each  other,  though  they  still  remain  in  mutual  contact ;  but  in  a  yet  later  stage  they 
are  found  detached  from  each  other  (D),  though  still  included  within  the  same  gelati 
nous  envelope.  Each  new  cell  then  begins  to  secrete  its  own  gelatinous  envelope,  so 
that,  by  its  intervention,  the  two  are  usually  soon  separated  from  one  another  (E). 
Sometimes,  however,  this  is  not  the  case, — the  process  of  subdivision  being  quickly 
repeated  before  there  is  time  for  the  production  of  the  gelatinous  envelope,  so  that  a 
series  of  cells  (F)  hanging  on  one  to  another  is  produced. 

Now  the  diatom aceae  grow  in  a  manner  precisely  similar  to  that  just 
described  as  taking  place  in  Palmogl&a.  This  subdivision  of  the  cell,  so 
that  the  new  individuals  are  formed  from  one  in  the  diatomaceae,  results 
in  the  production  of  a  series  of  frustules  almost  identical  in  all  particulars 
with  the  original  individual.  In  most  cases,  if  not  in  all,  the  new  indi 
viduals  differ  from  that  from  which  they  sprung  in  two  marked  respects : 
First,  they  each  possess  one  old  and  one  new  valve ;  and,  secondly,  the 
new  valve  is  smaller  than  the  old  one,  so  that  the  two  valves  of  all  dia 
toms  differ  somewhat  in  dimensions,  although  alike  in  other  respects. 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  447 

As  the  siliceous  exterior  skeleton  of  the  diatom  does  not  permit  of  its 
expanding  in  all  directions,  the  consequence  is  that  when  it  absorbs  nutri 
tive  material,  increases  in  bulk,  and  proceeds  to  subdivide,  it  must  mul 
tiply  its  bulk  in  one  direction  only ;  and,  as  the  two  valves  are  capable  of 
being  separated  one  from  the  other  along  the  line  of  junction  with  the 
connecting  membrane,  it  is  in  that  way  that  the  splitting  up  of  the  cell 
into  two  new  ones  takes  place.  The  existence  of  the  connecting  mem 
brane  in  the  perfect  diatomaceous  individual,  before  subdivision  starts,  is 
denied  by  many.  Under  those  circumstances,  the  siliceous  skeleton  con 
sists  of  only  two  parts,  the  valves,  to  which,  as  soon  as  subdivision  sets 
in  the  third  portion,  the  connecting  membrane  is  added.  In  Palmoglcea 
we  have  seen  that  the  perfect  cell  subdivides  by  a  process  which  shows 
itself  by  the  bending  in  of  the  cell  wall,  if  there  be  one,  or  by  the  pe 
riphery  of  the  mass,  if  there  be  no  limiting  membrane.  In  this  way,  at 
first,  two  united  and  similar  halves,  and  thereafter,  two  separate  individ 
uals,  are  formed  exactly  alike  in  all  particulars.  The  nucleus  and  nucle- 
olus,  if  there  be  one,  of  the  diatom  subdivide  at  the  same  time ;  and,  to 
make  room  for  the  increasing  cell-substance,  the  enclosing  valves  sepa 
rate  from  one  another,  the  space  all  around  between  them  being  closed  in 
by  the  new  hoop  of  siliceous  substance,  the  connecting  membrane  which 
now  makes  its  appearance  and  grows  by  additions  to  its  two  edges,  as  the 
accumulation  of  pabulum  by  the  growing  individual  goes  on.  At  the 
same  time,  two  new  valves  have  been  forming  exactly  like  the  two  old 
ones,  except  that  in  consequence  of  their  forming  entirely  within  the  con- 
'  necting  membrane,  which  has  the  same  diameter  as  the  old  valves,  they 
are  just  so  much  smaller;  and,  as  this  mode  of  subdivision  is  repeated 
again  and  again,  there  are  always  two  individual  diatoms  having  one  old 
and  one  new  valve,  which  latest  formed  valve  is  continually  being  replaced 
by  another  still  newer.  That  the  cell-contents  may  be  at  no  time  exposed 
to  direct  contact  with  the  surrounding  water,  the  connecting  membrane 
is  formed  of  two  pieces,  by  additions  next  to  the  two  valves ;  and,  as  one 
valve  of  the  diatom  individual  is  always  somewhat  smaller  than  the  other, 
one  of  these  sections  of  the  connecting  membrane  is  smaller  than  and 
slides  within  the  other.  In  some  cases,  however,  it  would  seem  that  the 
connecting  membrane  is  made  up  of  but  one  piece,  instead  of  two,  as 
described.  On  account  of  this  gradual  diminution  in  size  which  must 


448  PHYSICAL    GEOGRAPHY. 

take  place,  we  can  readily  understand  how  we  shall  be  very  likely  to  find 
diatoms  growing  together  which  are  exactly  alike,  except  that  they  vary 
in  size.  But  instead  of  the  smallest  being  the  oldest,  the  largest  were 
formed  first,  and,  by  the  process  of  subdivision  described,  they  have  grad 
ually  diminished  in  dimension.  And  it  would  seem  that  there  was  a  limit 
in  each  species  beyond  which  the  frustule  did  not  diminish,  but  as  soon 
as  it  was  reached,  then  the  stage  had  arrived  when  reproduction  sets  in 
in  the  manner  to  be  presently  described.  Thus  we  see  how  one  indi 
vidual  diatom  may  in  a  very  short  time  populate  a  large  lake  or  river ; 
but  all  of  these  separate  cells,  which  have  now  become  separate  individ 
uals  as  well,  will  very  closely  resemble  the  first  one  from  which  they 
sprung.  But  circumstances  may  occur,  while  this  rapid  growth  is  going 
on,  which  may  modify  the  characters  of  the  diatom  to  such  an  extent  that 
very  marked  variation  may  result.  Thus,  for  example,  if  the  original 
frustule  existed  at  the  head  waters  of  a  small  stream,  in  perfectly  fresh, 
running  water,  some  of  its  descendants  may  be  carried  down  into  a  lake 
where  they  may  lodge  along  the  shore,  in  still  water,  and  thus  become 
modified,  or,  they  may  pass  on  into  a  large  river,  to  be  there  affected,  or 
even  carried  down  to  its  mouth,  and  there,  where  the  salt  and  fresh  waters 
mingle,  be  changed  by  that  circumstance.  So,  of  course,  other  circum 
stances,  which  will  readily  present  themselves  to  the  mind,  will  serve  to 
form  and  perpetuate  variation  in  the  diatoms,  until  two  frustules,  de 
scended  from  the  same  progenitor,  by  growing  under  different  circum 
stances,  will  appear  so  unlike  that  they  may  be  classed  as  separate 
species,  or  even  as  belonging  to  separate  genera. 

The  time  occupied  in  a  single  act  of  self-division  in  the  diatoms  has 
not  been  ascertained  for  all  species,  although  it  has  been  lately  noted  for 
a  few;  "but  supposing  it  to  be  completed  in  twenty-four  hours,  we  should 
have,  as  the  progeny  of  a  single  frustule,  the  amazing  number  of  one 
thousand  millions  in  a  single  month, — a  circumstance  which  will,  in  some 
degree,  explain  the  sudden,  or,  at  least,  rapid  appearance  of  vast  numbers 
of  these  organisms  in  localities  where  they  were  but  a  short  time  pre 
viously  either  unrecognized,  or  only  sparingly  diffused." 

In  all  cases,  however,  the  two  newly  formed  frustules  do  not  entirely 
separate  from  each  other,  for,  after  subdivision  has  taken  place,  they 
remain  united,  so  that  in  time  others  will  be  added,  and  eventually  a  long 


NATURAL    HISTORY    OF    THE    DIATOMACE.E.  449 

ribbon-like  assemblage  of  individuals  result.  The  genera  Fragilaria, 
Hiuiantidinm,  and  Rhabdonema,  are  examples  of  such  a  mode  of  growth 
when  the  valves  are  oblong,  and  Mclosira  when  they  are  circular.  Then, 
again,  the  separation  may  be  partial,  so  that  the  frustules  remaining 
united  by  the  alternate  corners  are  attached  to  each  other,  and  a  zigzag 
chain  is  formed.  Diatoma  and  Grammatophora  are  examples  of  this. 
If  the  frustules  are  not  possessed  of  quite  parallel  sides,  but  if  they,  on 
the  contrary,  approach  each  other  at  one  end,  and  then  remain  united 
after  subdivision  has  taken  place,  a  fan-shaped  arrangement  will  result,  as 
is  seen  in  LicJnnapJwra ;  or,  if  subdivision  continues,  a  spiral  will  be 
formed  as  in  Meridian,  Those  forms  which  do  not  float  about  freely  in 
the  water  in  which  they  live  and  grow,  are  attached  to  submerged  objects 
by  either  a  small  gelatinous  cushion,  a  long  single  or  branching  stalk, 
pedicle,  or  "stipes,"  as  it  is  called.  And  there  are  forms,  as  ScJiizoncma, 
which  are  of  a  naviculoid  form,  but  which  secrete  around  themselves  a 
membranous  tube  within  which  the  process  of  subdivision  goes  on,  and 
up  and  down  the  cavity  of  which  the  little  boats  sail  with  extreme 
activity.  Thus,  from  this  simple  process  of  subdivision,  as  described, 
various  forms  may  result,  and  many  individuals  be  formed  which  shall 
have  their  number  still  further  increased  by  the  process  of  reproduction 
to  be  next  described. 

PART    FOURTH. 
REPRODUCTION  OF  THE  DIATOMACE^E. 

We  have  seen  the  manner  in  which  the  diatomaceae  increase  in  dimen 
sions,  or  grow,  and  observed  that  it  is  essentially  the  same  process  as 
that  which  takes  place  in  larger  and  apparently  more  complex  organisms, 
both  animal  and  vegetable.  That  is  to  say,  we  have  found  that  in  the 
case  of  the  diatomaceae  it  becomes  very  difficult,  if  not  impossible,  to 
distinguish  the  results  of  growth  from  the  results  of  reproduction.  And 
although  at  first  sight  this  may  appear  a  very  remarkable  fact,  yet  it 
ceases  to  be  so  if  we  remember  that  really  physiology  teaches  us  that 
reproduction  is  merely  a  form  of  modified  growth,  resulting  after  the 
casting  off  from  the  parent's  body  of  one  or  more  masses  of  matter  which 
possess  in  themselves  the  power  of  assimilation  of  food,  and  its  appro 
priation  for  the  building  up  and  elaboration  of  new  tissues.  Those  genera

45O  PHYSICAL    GEOGRAPHY. 

of  diatomaceas  which  occur  normally,  or,  we  should  say,  most  com 
monly,  attached  in  some  manner,  as  by  a  cushion,  pedicle,  stipes,  or  the 
surface  of  the  valve  or  connecting  membrane,  or  otherwise,  to  submerged 
objects,  would  never  become  very  widely  distributed  through  the  agency 
of  self-fission  alone,  as  it  has  been  described,  and  the  consequence  would 
be  that  they  would  be  confined  to  certain  localities  were  there  not  some 
other  mode  of  increase  or  reproduction.  To  a  certain  extent,  this  distri 
bution  is  provided  for  by  the  curious  movements  of  the  individual  which 
we  have  just  treated  of,  and  which  we  have  seen  are  quite  lively  in  some 
species.  But  it  is  still  more  perfectly  insured  by  the  process  of  repro 
duction  in  which  a  new  individual  is  developed  from  a  parent.  It  is  in 
the  form  of  spores  or  seeds  that  most  plants  (or,  at  least,  the  larger  ones 
with  which  we  are  acquainted)  are  enabled  to  endure  the  severe  frosts  of 
the  winter  months ;  and  the  same  is  likely  to  be  the  case  with  the  dia- 
tomaceaD,  although  it  is  true  that  some  species  are  to  be  found  living  and 
swimming  actively  about  beneath  the  frozen  surface  of  ponds  and  streams. 
And,  although  they  be  caught  within  the  mass  of  solid  ice,  yet  their 
vitality  does  not  seem  to  be  materially  compromised,  for,  on  thawing  the 
ice  they  again  move  about  in  a  lively  manner  in  the  water  formed.  Very 
little  investigation  has  been  carried  on  in  the  direction  of  the  reproduc 
tion  of  the  diatomaceae,  or,  rather,  we  should  say,  that  little  has  been 
published  in  this  connection,  so  that  we  have  few  authorities  to  draw 
upon  to  enlighten  us  on  this  point  in  the  economy  of  our  little  friends. 
From  what  little  has  been  observed  and  recorded  by  a  few  investigators, 
it  would  seem  that  the  diatomaceae  reproduce  after  a  manner  very  similar 
to  that  which  has  been  found  to  take  place  in  the  ProtopJiyta,  or  simple 
unicellular  plants  ;  and  this  fact  has  been  brought  forward  as  an  argu 
ment  in  favor  of  the  vegetable  nature  of  the  organisms  of  which  we 
are  treating. 

The  first  instance  in  which  the  process  of  reproduction  was  observed 
and  published  was  by  Mr.  Thwaites,  in  EpitJicmia,  a  genus  which  is 
almost  always  found  in  the  living  state,  attached  to  submerged  plants,  as 
mosses  and  the  like.  He  found  it  to  be  essentially  the  same  as  the  mode 
of  conjugation,  as  it  had  been  called,  known  to  take  place  in  several  algae 
or  water  plants  of  simple  organization.  He  describes  it  in  the  following 
manner:  "The  process  of  conjugation  consists  in  the  union  of  the  endo- 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  451 

chrome  of  two  approximated  fronds  [using  this  term  instead  of  frustule, 
to  indicate  the  perfect  individual],  this  mixed  endochrome  developing 
around  itself  a  proper  membrane,  and  thus  becoming  converted  into  the 
sporangium."  The  sporangium  is  what  may  be  called  the  seed  vessel,  as, 
although  it  does  not  contain  seeds,  in  the  ordinary  acceptation  of  that 
term,  yet  from  it  proceed  the  new  individuals  who  are  to  perpetuate  the 
species.  "In  a  very  early  stage  of  the  process,  the  conjugated  frustules 
have  their  concave  surfaces  [it  must  be  remembered  that  we  are  speaking 
of  Epithemia,)  whose  outline  is  somewhat  bow-shaped,  having  convex  and 
concave  surfaces]  in  nearly  close  opposition;  and,  it  may  be  observed, 
that  from  each  of  these  surfaces  two  protuberances  arise,  which  meet  two 
similar  ones  in  the  opposite  frustule;  these  protuberances  indicate  the 
future  channels  of  communication  by  which  the  endochrome  of  the  two 
frustules  becomes  united,  as  well  as  the  spot  where  is  subsequently  devel 
oped  the  double  sporangium,  or,  rather,  the  two  sporangia.  The  mixed 
endochrome  occurs  at  first  as  two  irregular  masses  between  the  connected 
(conjugating)  frustules ;  but  these  masses  shortly  become  covered  with  a 
smooth  cylindrical  membrane,  the  young  sporangia,  which  gradually  in 
crease  in  length,  retaining  nearly  a  cylindrical  form  until  they  far  exceed 
in  dimensions  the  parent  frustules,  and,  at  length,  when  mature,  become, 
like  them,  transversely  striated  upon  the  surface.  Around  the  whole 
structure  a  considerable  quantity  of  mucus  has  during  this  time  been 
developed,  by  which  the  empty  frustules  are  held  attached  to  the  sporan 
gia."  Thus  we  see  that,  whether  any  two  particular  frustules  are  drawn 
towards  each  other  or  not  (which  we  do  not  know),  yet  two  contiguous 
individuals  pour  out  their  respective  contents,  which,  melting  together, 
are  thus  fused  into  a  mass,  around  which  is  formed  one  or  two  new  sili 
ceous  coats  exactly  alike  in  structure,  but  only  differing  in  size,  being 
larger  than  those  which  enclose  the  parent  frustules.  Enveloping  these 
sporangia,  or  large  cases  from  which  the  new  individuals  shall  be  evolved, 
is  thrown  a  protecting,  or,  perhaps,  nutritive  globular  mass  of  transparent 
mucous  material.  In  different  genera,  slight  variations  are  met  with  in 
the  method  of  conjugation,  as  described.  Thus,  in  some  species  of  Gom- 
pJioncuia,  which  grows  attached  to  the  end  of  branching  stalks  or  stipes, 
very  much  after  the  manner  of  the  leaves  on  the  ends  of  the  twigs  of  a 
tree,  the  sporangia  lie  in  a  direction  parallel  to  the  empty  parent  frustules 


452  PHYSICAL    GEOGRAPHY. 

by  which  they  have  been  generated,  instead  of  across  them,  as  is  the  case 
in  EpitJicmia.  Although  in  many  cases  the  frustules,  which  are  about  to 
conjugate  and  form  sporangia,  split  into  two  separate  parts,  so  that  their 
contents  may  freely  coalesce,  we  find  that  there  are  examples  where  the 
valves  only  split  apart  at  one  end  to  a  slight  extent,  but  enough  to  serve 
for  the  escape  of  the  endochrome.  Instead,  also,  of  the  pair  of  conju 
gated  frustules,  producing  between  them  two  sporangia,  they  may  develop 
but  a  single  one.  The  Melosirce  and  BiddnlpJiue  (the  former  looking  like 
a  string  of  pill-boxes  attached  together  by  their  tops  and  bottoms ;  and 
the  latter  beins:  somewhat  like  a  number  of  wool-sacks  united  at  the  cor- 

o 

ners  into  a  chain),  Mr.  Thwaites  remarks,  "would  seem  in  their  develop 
ment  of  sporangia  to  offer  an  exception  to  most  diatomacea; ;  for,  in  those 
genera,  no  evident  conjugation  has  been  seen.  However,  something  anal 
ogous  to  it  must  take  place;  for,  excepting  the  mixture  of  endochromes 
of  two  cells,  the  phenomena  are  of  precisely  similar  character.  Thus, 
instead  of  the  conjugation  of  two  frustules,  a  change  takes  place  in  the 
endochrome  of  a  single  frustule;  that  is,  a  disturbance  of  its  previous 
arrangement,  a  moving  towards  the  centre  of  the  frustule,  and  a  rapid 
increase  in  its  quantity ;  subsequently  to  this  it  becomes  a  sporangium. 
In  a  single  cell,  therefore,  a  process,  physiologically  precisely  similar  to 
that  occurring  between  two  conjugating  cells,  takes  place;  and  it  is  not 
difficult  to  believe,  taking  into  view  the  secondary  character  of  cell- 
membrane,  that  the  two  kinds  of  endochrome  may  be  developed  at  the 
opposite  ends  of  one  frustule  as  easily  as  in  two  contiguous  frustules, 
and  give  rise  to  the  same  phenomena  as  ordinary  conjugation."  In  such 
genera  as  have  their  siliceous  frustules  enclosed  within  membranous 
tubes,  as  ScJiizoucina,  conjugation  seems  to  take  place  both  without  and 
within  the  tube,  but  oftenest  upon  the  outside.  As  has  been  remarked, 
"one  reason  for  the  paucity  of  observations  on  this  process  in  the  dia- 
tomaceae  is  no  doubt  to  be  found  in  the  changes  which  usually  take  place 
in  the  condition  of  these  organisms  at  this  period  of  their  existence. 
During  conjugation  the  process  of  self-division  is  arrested,  the  general 
mucus  envelope  or  stratum,  produced  during  self-division,  is  dissolved, 
and  the  conjugating  pair  of  frustules  become  detached  from  the  original 
mass;  they  are  thus  more  readily  borne  away  and  dispersed  by  the  sur 
rounding  currents,  or  the  movements  of  worms  and  insects,  and  their 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  453 

detection  becomes  in  consequence  more  casual  and  difficult."  The 
modes  of  conjugation  have  been  reduced  to  four  classes,  thus:  ist.  We 
have  two  parent  frustules  and  two  sporangia,  as  the  result  of  their  con 
jugation.  This  mode  has  been  seen  to  take  place  in  the  genera  EpitJi- 
cmia,  Cocconeina,  Gomphonema,  Encyonema,  and  Colletoncma.  2d.  From 
the  conjugation  of  two  parent  frustules  we  have  formed  a  single  sporan 
gium.  This  mode  has  been  only  seen  to  take  place  in  Himantidinm,  but 
most  likely  will  be  found  hereafter  to  be  natural  in  allied  forms.  3d. 
The  valves  of  a  single  frustule  separate,  the  contents  set  free,  rapidly 
increase  in  bulk,  and  finally  become  condensed  into  a  single  sporangium. 
This  has  been  seen  in  Cocconeis,  Cyclotclla,  Melosira,  OrtJwsira,  and 
ScJiizoncma.  4th.  From  a  single  frustule,  as  in  the  last  mode,  two  spo 
rangia  are  produced  in  the  process  of  conjugation.  This  takes  place  in 
Achnanthidium  and  RJiabdoncma.  Thus  far  has  observation  gone ;  but 
no  one  seems  to  have  traced  the  further  history  of  the  sporangium.  For 
we  find  no  record  of  the  undoubted  production  of  gonidia,  as  they  are 
called,  or  seeds  possessed  of  motion,  from  the  contents  of  the  sporan 
gium.  In  fact,  we  have  no  proof  that  such  contents  are  developed  into 
spores,  still  or  motile.  It  is  true  that  Rabenhorst,  a  German  observer, 
has  figured  and  described  what  he  supposes  to  be  the  development  of 
gonidia  or  motile  spores  from  the  contents  of  a  sporangium  in  a  filament 
of  filelosira  varians,  an  extremely  common  species  found  growing  in 
fresh  water  in  all  quarters  of  the  globe.  It  would  seem  strange,  there 
fore,  that  others  have  not  seen  the  same  thing ;  and  later  observers  have 
doubted  his  record  for  this  reason  alone,  apparently,  that  they  have  not 
chanced  to  see  it.  However,  Smith,  one  of  the  best  of  the  English 
authorities  on  this  subject,  says, — "On  the  whole,  the  facts  at  present 
within  our  knowledge  seem  fully  to  warrant  the  conclusions  that  the 
conjugated  state  of  the  diatomaceas  is  the  first  step  in  the  reproduction 
process  of  these  organisms ;  and  that  the  sporangial  products  of  this 
condition  become  the  parents  of  numerous  young  frustules  destined  to 
renew  the  cycle  of  phenomena  which  accompanies  the  life  and  growth  of 
the  species  from  which  the  sporangia  have  thence  originated."  It  is  very 
likely  that  the  contents  of  the  sporangium  are  converted  into  spores  or 
gonidia,  as  Rabenhorst  has  stated,  and  that  after  escaping  and  moving 
rapidly  about,  and  thus  aiding  in  distributing  the  species,  these  gonidia 


454  PHYSICAL    GEOGRAPHY. 

develop  around  themselves  siliceous  shells  or  skeletons,  and  become  dia 
toms  of  the  normal  dimensions  of  the  species  from  and  by  which  the 
sporangium  was  produced.  On  the  other  hand,  the  sporangia  may  con 
stitute  the  "resting"  state,  such  as  is  known  to  occur  in  several  simple 
forms  of  life,  in  which  the  species  encounters  the  severity  of  the  winter 
only  to  reproduce  the  species  in  the  spring.  In  this  case,  examination  of 
localities,  known  to  produce  certain  species  during  the  summer,  should, 
during  the  winter  months,  be  searched  when  most  likely  there  would  be 
found  abundance  of  sporangial  forms.  I  am  not  aware  that  any  such 
investigations  have  been  as  yet  made ;  and  the  difficulties  surrounding 
the  study  of  these  organisms  is  so  great  that  but  few  have  the  patience 
requisite  for  such  work.  Hence  we  find  that  most  of  the  papers  relating 
to  the  diatomaceae,  which  have  been  published,  are  by  persons  who  de 
light  in  the  naming  of  "new  species,"  and  have  not  cared  to  spend  the 
time  necessary  to  determine  whether  they  be  but  transition  forms,  spo 
rangia,  or  true  species. 

Although,  then,  as  has  been  said,  the  whole  life-history  of  the  diato- 
maceous  sporangium  has  not  been  established,  yet  we  know  enough  to 
convince  us,  as  Prof.  Smith  says,  that  "the  ordinary  diatomaceous  frus- 
tule  seems  to  owe  its  production  to  the  protoplasmic  contents  of  the 
sporangial  frustule  formed  by  the  process  of  conjugation.  These  spo 
rangia,  like  the  seeds  of  higher  plants,  often  remain  for  a  long  period 
dormant,  and  are  borne  about  by  currents,  or  become  imbedded  in  the 
mud  of  the  waters  in  which  they  have  been  produced,  until  the  circum 
stances  necessary  to  their  development  concur  to  call  them  into  activity. 
At  such  times,  their  siliceous  epiderms  open  to  permit  the  escape  of 
the  contained  endochrome,  which  is  resolved  into  a  myriad  of  embryonic 
frustules ;  these  either  remain  free,  or  surround  themselves  with  mucus, 
forming  a  pellicle  or  stratum,  and,  in  a  definite  but  unascertained  period, 
reach  the  mature  form  of  the  ordinary  frustule."  Prof.  Smith  has  made 
observations  which  appear  to  establish  this  fact  of  the  formation  of 
motile  spores,  which  he  details  in  the  following  words :  "  In  the  gathering 
of  Cocconcina  Cistnla,  made  in  April,  1852,  which  contained  numerous 
instances  of  the  conjugating  process,  I  observed  the  frequent  occurrence 
of  cysts  enclosing  minute  bodies,  variable  in  their  number  and  size,  and 
many  of  which  had  the  outline  and  markings  of  the  surrounding  forms, 


NATURAL    HISTORY    OF    THE    DIATOMACE7E.  455 

and  were  obviously  young  frustules  of  the  Cocconema.  It  would  appear 
that  production  of  the  young  frustules  is  preceded  by  the  separation  and 
throwing  off  of  the  siliceous  valves  of  the  sporangium,  and  the  constric 
tion  or  enlargement  of  its  primordial  utricle,  according  to  the  number  of 
young  frustules  originating  in  its  protoplasmic  contents.  In  this  gather 
ing,  forms  of  every  size,  intermediate  between  the  minutest  frustule  in 
the  cyst  and  the  ordinary  frustules  engaged  in  the  conjugating,  were 
easily  to  be  detected ;  and  the  conclusion  was  inevitable  that  the  cysts 
and  their  contents  were  sporangia  of  the  species  with  which  they  were 
associated,  and  indicated  the  several  stages  of  the  reproductive  process." 
Although  this  observation  seems  to  confirm  the  supposition  that  the  con 
tents  of  the  sporangium  must  divide  into  a  number  of  small  frustules 
similar  to  the  parents  from  which  the  sporangium  sprung,  yet  further 
study  is  necessary  before  we  can  consider  this  fact  established ;  and  such 
study  can  only  be  carried  out  by  those  who  are  willing  to  keep  alive  for 
hours,  days,  or  even  weeks,  such  forms  as  they  may  meet  with,  and 
spend  hours  at  a  time  at  the  microscope,  watching  any  change  that  may 
take  place  in  them. 

Thus  do  we  see  the  diatomaceous  frustule  becoming  gradually  smaller 
and  smaller,  through  the  carrying  on  of  the  process  of  self-division,  and 
its  return  to  the  normal  dimensions  through  conjugation,  or  the  forma 
tion  of  gigantic  sporangia,  whose  cell-contents  shall  return  by  subdivi 
sion,  and  the  genesis  of  motile  spores  to  the  size  of  the  parent  frustules. 
A  perfect  cycle  of  changes  would  seem  to  be  thus  kept  up,  such  as  is  by 
no  means  uncommon  in  the  life-history  of  many  simple  plants  grouped 
under  the  head  Protophyta.  And  we  are  at  the  same  time  reminded, 
when  witnessing  these  changes  and  transformations,  of  the  equally  won 
derful  metamorphoses,  well  known  to  naturalists,  to  take  place  in  the 
jelly-fish  and  hydroids  of  our  coast,  or  those  of  the  insect  world,  and 
which  we  see  going  on  day  by  day  around  us.  The  egg  becomes  a  grub, 
the  grub  a  caterpillar,  which,  in  turn,  changes  into  the  quiescent  chrys 
alis,  in  which  commonly  the  winter  is  passed,  only  to  burst  forth,  as  soon 
as  the  revivifying  rays  of  the  spring  sun  warm  it  into  being,  as  the  gor 
geously  tinted  and  active  butterfly,  the  parent  of  innumerable  eggs, 
which  shall  in  turn  produce  another  generation  of  grubs.

PART     FIFTH. 
MODES  OF  OCCURRENCE,  AND  USES  TO  MAN  OF  THE  DIATOMACE.E. 

And  now  it  will  be  desirable  to  say  something  with  regard  to  the 
various  modes  of  occurrence  of  the  diatomaceac:,  specifying  the  particu 
lar  habitats  or  kinds  of  situations  or  water  (salt,  fresh,  or  brackish),  for 
the  use  of  such  as  may  wish  to  know  more  concerning  these  beautiful 
atomies  than  can  be  told  within  the  limits  of  a  short  sketch  like  the 
present.  Thereafter  it  will  be  well  to  say  something  of  the  importance 
to  the  geologist  of  knowing  the  life-history  of  the  diatomaceae,  and, 
finally,  their  uses  to  man  in  the  arts  and  otherwise,  as  they  occur  in 
mass  in  various  parts  of  the  world.  And  in  this  connection  we  are 
reminded  of  the  words  of  the  poet,  who  says, — 

Naught  so  vile  that  on  this  earth  doth  live, 
But  to  the  earth  some  special  good  doth  give ; 

for  we  find  that  the  diatomaceae  have  in  past  ages  played,  and,  in  truth, 
still  are  playing,  a  most  important  part  in  the  grand  drama  of  nature; 
and  their  minute  dimensions  is  no  excuse  for  the  neglect  to  which  they 
have  been  subjected  by  scientific  and  capable  observers. 

Diatomaceae  are  to  be  looked  for  in  both  fresh  and  salt  water,  as  well 
as  in  that  which  can  be  included  under  neither  of  these  heads,  the  brack 
ish  water  of  seaside  marshes,  where  the  springs  of  to-day  are  overflowed 
by  the  rising  tide  of  to-morrow.  In  general,  the  piece  of  water  in  which 
they  are  looked  for  must  be  permanent,  for  authors  tell  us  that  it  is  use 
less  to  expect  to  find  them  in  the  transient  pools  left  by  the  rain.  This 
is,  however,  not  strictly  the  case,  for,  on  one  occasion,  I  found  diatoms  in 
a  pool  formed  by  the  drainings  of  a  stable-yard,  and  even  little  collec 
tions  of  water  only  two  or  three  days  old  have  occasionally  yielded  forms 
when  carefully  searched,  but  in  such  cases  they  were  only  few  and  mi 
nute.  Prof.  Gregory  found  them  in  moist  earth  about  the  roots  of  plants, 
and  others  have  collected  them  from  between  the  branches  of  mosses 
which  clustered  upon  tree  barks  or  house-tops.  Even  the  dust  which 
has  fallen  upon  the  sails  and  decks  of  vessels,  far  out  at  sea,  have  been 
found  to  contain  them,  by  the  German  microscopist,  Ehrenberg,  who 
therefrom  has  deduced  certain  supposed  facts  with  regard  to  atmospheric 


NATURAL    HISTORY    OF    THE    DIATOMAEC7E.  457 

currents.  Upon  these  foundations  Maury  has  formed  theories  which, 
however  true  they  may  be  in  themselves,  are  not  borne  out  by  later 
researches,  for  the  forms  which  Ehrenberg  supposed  to  be  peculiar  to 
certain  quarters  of  the  globe  have  been  found  to  be  almost  universally 
distributed ;  and,  therefore,  any  deductions,  which  may  have  been  estab 
lished  in  consequence  of  their  appearance  upon  a  ship,  do  not  prove  that 
they  were  brought  from  the  spot  where  they  were  first  seen.  In  fact, 
the  diatomaceae  would  seem  to  be  more  widely  distributed  than  any  other 
group  of  organisms,  animal  or  vegetable ;  and  the  student  of  them  need 
never  be  at  a  loss  for  specimens  to  examine.  The  pool  by  the  road-side, 
the  mud  of  the  river  bank,  the  moss  upon  the  house-top,  the  earth  be 
neath  his  feet,  or  the  air  above  his  head,  may  be  searched,  and  will  all  of 
them  yield  him  material  for  observation,  wonder,  and  delight.  In  the 
living  state,  and,  as  often  found,  floating  upon  the  surface  of  the  water 
of  a  pond  or  slowly  running  river,  swamp,  or  ditch,  the  diatoms  present 
themselves  as  a  flocculent  collection  of  more  or  less  dark  rust-colored 
matter,  coherent  in  stringy  masses,  when  such  genera  as  Melosira,  Frag- 
ilaria,  or  Himantidium  occur,  or  consisting  of  particles  readily  dispersed 
and  scattered  when  Navicula,  Pinnularia,  or  other  so-called  free  genera 
exist.  The  color  of  such  a  mass  may  vary  from  a  golden  orange  to  a 
dark  brown,  according  to  the  thickness  of  the  stratum  or  particular  spe 
cies  present,  or,  it  may  take  on  a  greenish  tinge  at  certain  seasons,  which 
is  supposed  to  indicate  a  change  in  the  character  of  the  endochrome 
having  some  connection  with  the  process  of  reproduction.  At  times,  I 
have  found  that  bright  green  masses  of  floating  confervae, — which  are 
filamentous  water-plants  found  in  all  waters,  both  fresh  and  salt, — will 
yield  beautiful  specimens  of  diatoms,  which  are  entangled  among  their 
branches,  or  grow  adherent  to  them.  But  in  most  of  such  cases  the 
species  belong  to  the  group  of  adherent  forms,  and  for  those  we  are  to 
look  to  submerged  plants,  sticks,  metal,  and  stones,  and  there  they 
appear  as  a  brownish  or  fawn-colored  mass,  either  closely  adherent,  or 
with  its  free  ends  floating  freely  in  the  water,  as  delicate  threads,  borne 
hither  and  thither  by  the  changes  of  the  current.  A  sprig  of  some 
submerged  plant,  bearing  a  cluster  of  some  such  genus  as  Himan 
tidium,  Fragilaria,  or  Tabcllaria,  presents  a  beautiful  object,  as  the  fine 
hair-like  filaments  spread  out  on  all  sides,  or  bend  with  the  motion  of  the

45 S  PHYSICAL    GEOGRAPHY. 

containing  water.  A  very  little  practice  will  enable  the  searcher  after 
diatoms  to  distinguish  them,  or  to  choose  localities  likely  to  yield  them. 
I  have  found  that,  if  the  adherent  mud  on  the  submerged  wood-work  of 
a  bridge  or  pier  be  scraped  off  and  transferred  to  a  bottle  with  some 
water,  and,  when  brought  home,  be  placed  in  a  saucer  or  plate,  covered 
with  the  water  and  exposed  to  the  diffused  sunlight  which  comes  in  at  a 
south  window,  many  very  beautiful  forms  may  be  procured  in  sufficient 
quantity  for  observation ;  and,  besides,  in  such  saucers  the  diatoms  may 
be  kept  and  grown  for  a  length  of  time,  and  many  points  in  their  econ 
omy  studied  with  facility.  Thus  they  may  be  watched  through  the 
process  of  growth  by  subdivision  and  conjugation,  and  the  changes 
which  they  then  undergo  observed  without  being  under  the  necessity 
of  making  several  visits  to  their  native  localities  to  make  collections. 
The  dead  skeletons  of  many  rare  species  are  to  be  found  in  the  muds  of 
our  tidal  rivers  and  harbors,  that  from  some  of  our  southern  streams 
especially,  where  the  summer  season  of  vigorous  growth  lasts  longer 
than  with  us,  having  yielded  forms  not  otherwise  procurable.  All  algae, 
as  the  water-plants  which  do  not  bear  apparent  flowers  are  called,  both 
marine  and  fresh  water,  bear  upon  their  fronds  diatoms  in  greater  or  less 
numbers ;  and  the  results  of  dredgings  in  deep  water  will  provide  the 
student  with  ample  material  for  many  an  hour's  amusement  and  instruc 
tion.  The  various  methods  to  be  employed,  in  preparing  clean  or  mixed 
gatherings  of  diatomaceae,  can  for  the  most  part  only  be  learned  from 
experience,  as  the  books  tell  us  little  on  this  subject.  Some  general 
directions,  however,  on  this  point  will  be  appropriate  to  this  sketch,  and 
will  be  given  hereafter.  As  the  diatomaceae  live,  grow,  and  multiply, 
thus  floating  freely  on  the  surface,  along  the  bottom,  or  through  the 
mass  of  the  water,  or  wave  in  tiny  filaments  from  other  objects,  they 
must  die ;  and  the  most  perishable  part  of  their  bodies,  namely,  the  cell- 
contents,  will  be  dissolved  in  the  water  or  dissipated  in  gases,  to  return 
and  again  build  up  new  individuals  at  some  future  time.  But  their  less 
perishable  portions,  their  siliceous  skeletons,  will  fall  to  the  bottom  of 
the  pond,  lake,  ocean,  or  river,  and  there  collect.  Their  remains  will 
also  be  found  in  the  stomachs  of  such  animals  as  are  vegetable  feeders, 
as  are  most  of  the  mollusca,  like  the  oyster,  the  clam,  and  the  water 
snails,  as  well  as  the  Crustacea, — lobsters,  crabs,  and  the  like.  So,  like- 


NATURAL    HISTORY    OF    THE    DIATOMACEyE.  459 

wise,  the  alimentary  canals  of  sea  urchins  and  sea  cucumbers,  as  they 
are  commonly  called,  but  whose  correct  and  scientific,  although,  perhaps, 
at  first  more  incomprehensible  names  are  echinoderms  and  holothurians, 
as  well  as  many  fish  and  countless  smaller  creatures  inhabiting  the 
waters,  both  fresh  and  salt,  will  be  found  to  contain  the  skeletons  of 
diatoms  which  they  take  in  directly  as  food,  or  indirectly  when  browsing 
upon  the  algae  and  other  examples  of  aquatic  vegetation.  So  the  exami 
nation  of  the  half-digested  food,  from  the  stomachs  of  these  creatures, 
will  often  repay  the  trouble  of  preparing  it  for  the  microscope.  And 
here  is  an  appropriate  opportunity  of  saying  something  with  regard  to 
that  remarkable  and  important  substance  which  goes  by  the  name  of 
guano,  and  which  has  proved  to  be  an  almost  inexhaustible  storehouse 
for  beautiful  forms  of  diatomaceae.  Very  generally  this  substance  is 
supposed  to  be  the  excrements  of  birds,  which  has  accumulated  in  large 
quantities  during  the  lapse  of  many  years  upon  the  rocky  islands  in  the 
Pacific  ocean  and  elsewhere,  in  latitudes  where  little  or  no  rain  falls  to 
wash  out  the  organic  matter.  This  substance  has  been  used  by  the 
inhabitants  of  the  coast  of  South  America  from  time  immemorial  as  a 
manure  ;  and,  since  it  was  introduced  into  Europe  by  Humboldt,  in  1804, 
it  has  been  largely  exported  to  that  country  and  this,  to  supply  the 
exhaustion  of  our  fields  by  the  continuous  crops  necessitated  by  our 
always  increasing  population. 

Some  years  since,  the  attention  of  the  writer  of  this  sketch  was  called 
to  the  subject  of  guano,  when  engaged  as  an  analytical  chemist  in  exam 
ining  fertilizers  of  different  kinds;  and  thereafter,  when  studying  the 
diatomaceae  and  the  application  of  a  knowledge  of  them  to  geology,  he 
pushed  his  investigations  still  further,  and  at  last  came  to  the  conclusion 
that  the  popular  prevalent  notion  with  regard  to  the  origin  of  guano  was 
erroneous.  His  ideas  on  the  subject  he  embodied  in  a  communication 
made  to  the  Essex  Institute  of  Salem,  Mass.,  on  the  4th  of  January, 
1869,  an  abstract  of  which  will  be  found  in  the  Bulletin  of  the  Associa 
tion,  vol.  I,  p.  ii.  Subsequently,  with  the  Hon.  E.  G.  Squier  and  Dr. 
A.  Habel,  who  had  visited  the  celebrated  Chincha  islands,  and  there 
observed  some  facts  which  confirmed  the  present  writer's  notions  with 
regard  to  it,  he  again  brought  the  subject  prominently  before  the  public 
at  a  meeting  of  the  New  York  Lyceum  of  Natural  History,  held  May  I, 


460  PHYSICAL    GEOGRAPHY. 

1871.  (Proceedings  Lye.  Nat.  Hist.  N.  Y.,  vol.  I,  p.  224.)  Therein  it  is 
shown  that  guano  is  most  likely  not  the  excrements  of  birds  or  other 
similar  animals,  deposited  upon  the  islands  and  main  land  after  their 
upheaval,  but  that  it  is  the  result  of  the  accumulation  of  the  bodies  of 
animals  and  plants,  for  the  most  part  minute,  the  diatomaceae  making  up 
a  large  part  of  the  mass,  and  subsequently  upheaved  from  the  bottom 
of  the  ocean  by  volcanic  agency,  which  is  known  to  be  very  active  and 
pretty  constant  in  that  part  of  the  world.  In  this  way  guano  has 
become  a  storehouse  of  many  otherwise  rare  and  beautiful  forms  of 
diatomaceae,  which  can  be  procured  from  it  by  employing  a  proper  pro 
cess  with  chemicals  to  destroy  and  remove  everything  but  the  siliceous 
skeletons,  which  are  then  left  in  all  their  purity,  so  that  their  forms 
may  be  viewed  by  means  of  the  microscope.  The  process  for  cleaning 
guano,  so  as  to  obtain  the  microscopic  organisms  contained  in  it,  will 
be  described  hereafter. 

In  a  semi-fossil  condition,  the  diatomaceae  are  to  be  found  in  all  parts 
of  the  world,  and  very  extensively  within  the  state  of  New  Hampshire 
in  the  form  of  what  have  been  called  lacustrine  sedimentary  deposits, — 
that  is  to  say,  collections  of  their  dead  skeletons  formed  at  the  bottom 
of  lakes,  and  going  commonly  by  the  name  of  "marl,"  although  true  marl 
contains  few,  if  any,  diatoms,  and  is  largely  made  up  of  the  shells  of 
mollusca,  snails,  and  the  like.  The  mode  of  formation  of  these  deposits 
will  be  described  hereafter. 

Still  more  ancient,  and,  what  may  be  with  propriety  termed  truly  fossil 
deposits  of  fresh-water  diatomaceae,  are  not  found  on  this  coast  of  the 
North  American  continent,  but,  in  fact,  appear  to  be  confined  to  the 
Pacific  states,  where  they  cover  vast  tracts  of  country.  Their  mode  of 
formation  will  be  described  when  we  come  to  treat  of  the  application  of 
a  knowledge  of  the  diatomaceae  to  geology,  in  a  subsequent  part  of  this 
sketch.  Thus  extensive  strata  of  diatomaceae  have  accumulated  and 
become  fossilized,  and  constitute  the  "infusorial  earths"  of  geologists 
and  others,  many  of  those  on  our  Pacific  coast,  as  has  been  said,  being 
made  up  of  the  remains  of  fresh-water  species  which  have  lived,  grown, 
died,  and  been  laid  up  in  countless  millions  in  the  beds  of  now  extinct 
lakes ;  while,  likewise,  in  California,  as  well  as  in  Virginia  and  Maryland, 
in  Peru,  Japan,  and  Algeria,  are  found  layers  which  are  made  up  of  the 


NATURAL    HISTORY    OF    THE    DIATOMACEvE.  461 

skeletons  of  marine  species.  The  city  of  Richmond,  Va.,  rests  upon 
such  a  stratum,  which  varies  in  thickness  from  twelve  to  twenty-five  feet, 
and  which  extends  to  Fortress  Monroe  and  over  the  Potomac  river  into 
Maryland,  and  all  the  way  down  on  both  sides  of  the  Patuxent  river  in 
that  state.  The  principal  localities  from  which  these  deposits,  fresh 
water  and  salt-,  have  been  obtained  so  far,  will  be  mentioned  in  the 
directions  for  collecting,  to  be  given  hereafter. 

Besides  objects  of  great  beauty  and  scientific  interest,  the  uses  to 
which  the  diatomaceae  have  been  put  may  be  briefly  summarized.  It 
is  to  be  hoped  that  the  unlearned,  whose  attention  has  for  the  first  time, 
perhaps,  been  called  to  them  by  this  sketch,  will  feel  that  the  elegance 
of  their  forms  and  the  geometrical  purity  of  their  sculpture  will  recom 
mend  them  sufficiently,  without  eliciting  the  question,  which  unfortu 
nately  has  been  propounded  with  reference  to  other  scientific  subjects, 
viz.,  What  good  are  they  ?  That  they  serve  as  food  for  numerous 
aquatic  animals  is  plainly  shown  by  the  fact  of  their  being  found  in 
their  stomachs ;  but,  if  that  were  their  only  use,  it  could  hardly  be 
said  that  they  were  of  value  to  man  directly.  Who  would  suppose 
that  these  little  atomies,  so  seemingly  insignificant,  could  serve  as  sus 
tenance  for  the  human  race? — and  yet  such  is  the  fact.  In  the  bleak 
and  almost  barren  parts  of  Lapland,  during  times  of  scarcity  from  failure 
of  the  crops,  the  infusorial  deposits  are  turned  to  account,  under  the 
name  of  "berg-mekl"  or  mountain  meal,  to  eke  out  the  scanty  supply  of 
flour  with  which  they  are  mixed  before  it  is  made  up  into  bread  and 
eaten.  In  some  other  parts  of  the  world  we  find  wild  nations  making  a 
similar  use  of  such  "infusorial  deposits;"  but  we  can  hardly  say  they 
serve  as  food,  for  although  some  authors  have  supposed  that  some  of  the 
organic  matter  they  contain  may  be  absorbed  by  the  stomach  or  intes 
tines,  it  is  not  likely  that  such  is  the  case.  It  is  much  more  probable 
that  the  earthy  material  serves  to  clog  the  stomach,  and,  by  the  mere  act 
of  distention,  arrest  for  a  time  the  pangs  of  hunger.  Their  siliceous 
character  is  opposed  to  their  serving  as  food  in  the  true  acceptation  of 
that  word.  In  Samarancy  and  Java,  under  the  name  of  "tanah,"  an 
earth  of  this  kind,  made  up  of  the  siliceous  remains  of  diatomaceae,  is 
eaten.  It  is  described  as  "generally  solid,  plastic,  and  sticky,  and  is 
rolled  and  dried  in  the  shape  of  small  sticks  over  a  charcoal  fire,  and  is

eaten  as  a  delicacy."  The  natives  of  our  western  coast,  as  well  as  the 
inhabitants  of  some  parts  of  South  America,  use  an  "infusorial  earth"  as 
a  pigment  to  decorate  their  bodies.  In  guano,  doubtless  the  diatomaceae 
play  a  very  important  part,  when  that  substance  is  employed  as  a  fertil 
izer  and  spread  upon  our  fields,  for  they  then  present  the  silica  in  an 
extremely  minute  state  of  division  to  the  moisture  of  the  soil  and  the  air, 
which  gains  admittance  thereto,  either  along  with  the  water  or  on  account 
of  the  porosity  of  the  earth.  It  has  been  found  that  under  these  circum 
stances  the  silica  is  dissolved  and  absorbed  by  the  plant  that  requires  it, 
in  whose  tissues  it  is  deposited  to  form  a  strong  support  to  its  frame 
work.  The  cereals  especially  require  a  certain  amount  of  silica,  as  is 
well  known,  for  the  strengthening  of  the  stem  which  serves  to  elevate 
the  seed  where  it  gets  the  benefit  of  the  sun  and  the  air.  So  we  find 
that  all  the  grasses,  as  wheat,  oats,  sugar-cane,  maize,  grow  best  on  a 
soil  from  which  they  can  abstract  sufficient  silica  for  the  purpose  indi 
cated.  Instances  have  come  to  my  knowledge  where  recent  wet  deposits 
of  diatomaceae,  especially  those  containing  organic  matter,  and  men 
tioned  above  under  the  designation  of  lacustrine  sedimentary,  have 
proved  of  real  value  as  fertilizers,  when  mixed  with  stable  manure  and 
used  for  cereals,  but,  of  course,  they  would  be  objectionable  if  applied 
to  root,  fruit,  or  leaf  crops. 

Many  deposits  of  diatomaceae  are  called  tripoli  and  polishing  pow 
ders;  and  these  names  indicate  that  they  are  possessed  of  properties 
which  peculiarly  fit  them  for  polishing  hard  surfaces,  such  as  metal. 
The  extremely  minute  state  of  division  of  the  silica  in  the  diatom-valves, 
and  the  readiness  with  which  those  valves  are  fractured  and  broken  down 
into  still  smaller  angular  portions,  are  remarkable,  and  could  hardly  be 
imitated  by  any  artificially  prepared  powder.  It  has  been  suggested  that 
the  vast  diatomaceous  deposits  found  in  some  parts  of  the  world,  as  the 
strata  occurring  in  Virginia  and  California,  might  be  turned  to  account, 
as  presenting  silica  in  a  fine  state  of  division,  so  that  it  can  readily  be 
acted  upon  by  the  alkali,  and  the  so-called  "soluble  glass"  made  there 
from.  One  manufacturer  has  experimented  somewhat  in  this  direction, 
but  with  what  result  is  at  present  unknown. 

It  is,  however,  to  the  scientific  student  that  the  diatomaceae  are  of  the 
greatest  interest  and  really  of  use,  for  they  have  proved  valuable  in 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  463 

assisting  him  in  the  investigation  of  various  subjects,  as  the  matter  of  the 
conditions  of  existence  of  the  simple  cell,  and,  likewise,  the  former  char 
acters  of  certain  strata  in  which  they  are  found  in  vast  numbers.  The 
bearings  of  this  latter  subject  will  occupy  our  attention  in  Part  Sixth. 

PART    SIXTH. 

THE    DlATOMACE^E    AND    GEOLOGY. 

The  manner  in  which  the  diatomaceae  increase,  both  by  true  growth 
and  reproduction,  has  been  described  in  such  detail  that  it  is  to  be  hoped 
that  it  is  thoroughly  understood.  At  the  same  time,  it  can  be  readily 
comprehended  how,  as  they  secrete,  from  its  solution  in  the  water  in 
which  they  live,  the  siliceous  material  constituting  their  harder  parts, 
and,  as  they  die,  this  flinty  matter  must  after  a  time  form  a  deposit  at 
the  bottom  of  the  lake  or  ocean  which  they  inhabit.  We  are,  then,  pre 
pared  to  take  into  consideration  the  formation  of  such  deposits,  both 
fresh  and  salt,  and  their  connection  with  the  science  of  geology. 

The  mode  of  formation  of  fresh-water  deposits  of  diatomacese,  as 
lacustrine  sedimentary  strata  and  as  fluviatile  fossil  layers,  has  been 
fully  described  in  a  paper  read  by  the  present  writer  before  the  New 
York  Lyceum  of  Natural  History,  Nov.  28,  1870,  and  published  in  the 
proceedings  of  that  association,  vol.  I,  p.  109;  and  the  major  part  of  that 
communication  will  be  given  here  as  embodying  about  all  that  is  known 
on  that  subject,  and  detailing  at  the  same  time  the  author's  ideas  with 
regard  to  the  enormous  deposits  of  fresh-water  diatomaceas  found  spread 
over  many  parts  of  the  western  states  of  the  North  American  continent. 

We  have  seen  how  the  diatomacese  increase  by  subdivision,  so  that  by 
this  means  alone  they  may  multiply  extremely  rapidly,  a.nd  a  single  indi 
vidual,  by  means  of  its  descendants,  soon  populates  a  large  pond  or  lake. 
But  while  subdivision  or  true  growth  has  been  thus  progressing,  increase 
by  generation  or  seeding  may  have  taken  place  at  the  same  time,  and, 
from  each  individual  in  turn,  several  young  may  have  been  brought 
forth,  which  would  multiply  the  rate  of  increase  very  materially,  of 
course.  It  is  true  that  the  mode  of  seeding  of  these  organisms  is  not 
thoroughly  understood ;  but  we  know  enough  to  say  that  it  does  occur, 
and  very  frequently,  and  that  the  number  of  new  individuals  thus  formed 
is  very  great.  At  the  same  time,  numerous  individuals  are  dying,  and, 


464  PHYSICAL    GEOGRAPHY. 

as  they  do  so,  much  of  the  organic  matter  of  which  they  are  composed 
is  dissipated,  but  some  of  it,  along  with  the  hard  siliceous  valves  and 
connecting  membranes  which  constituted  the  skeletons  of  the  diatoms, 
falls  to  the  bottom  of  the  pond,  and  forms  a  layer  of  greater  or  less 
thickness,  according  to  the  time  during  which  it  has  been  accumulating. 
If  it  be  exposed  now,  by  draining  such  a  pond,  it  may  appear  as  a  brown 
or  grey  powdery  mass,  but,  if  it  has  rested  beneath  the  the  water  suffi 
ciently  long,  almost  all  of  the  organic  matter  will  be  removed,  and  the 
clean,  white  siliceous  skeletons  alone  remain.  In  some  localities, — and 
this  I  have  found  to  be  the  case  in  the  state  of  New  Hampshire,  perhaps 
from  the  peculiar  topography  of  the  spots  where  these  masses  of  the 
accumulated  dead  shells  of  diatoms  are  found, — these  organisms  grow  in 
bogs  of  no  very  great  superficial  extent,  but  which,  from  their  occurring 
in  hollows  between  hills,  are  often  quite  deep.  Under  such  circum 
stances,  as  I  should  judge  from  the  character  of  a  deposit  I  examined  at 
Bowkerville  in  Cheshire  county,  the  organic  matter  might  for  the  most 
part  decay  out  of  a  layer  of  considerable  thickness,  and  nothing  be  left 
but  a  mass  of  finely  divided  siliceous  material  of  a  character  well  fitted 
for  use  as  a  polishing  powder,  or  for  other  purposes  to  which  this  sub 
stance  has  been  applied. 

Such  are  the  results,  then,  of  this  rapid  growth  of  the  diatomaceas  in 
ponds,  lakes,  marshes,  and  rivers ;  and,  as  the  first  examples  of  such 
deposits  which  I  examined  were  found  beneath  layers  of  peat,  I  gave  to 
them  the  name  "sub-peat"  deposits,  and  under  that  designation  they 
have  been  generally  known.  After  a  time,  however,  specimens  came 
into  my  hands  which  were  procured  from  the  bottoms  of  existing  ponds, 
and  these,  besides  consisting  for  the  most  part  of  little  else  than  silica, 
and  being  of  an  almost  pure  white  color,  had  no  peat  overlying  them. 
Hence,  of  course,  I  saw  the  inapplicability  of  the  term  "sub-peat"  to 
such  deposits,  and  for  them  I  have  coined  a  new  name,  viz.,  lacustrine 
sedimentary,  which  I  consider  more  appropriate,  and  at  the  same  time 
indicating  their  usual  origin,  and  including  all  deposits  of  fresh-water 
diatomaceous  remains,  with  the  exception  of  certain  peculiar  layers  to 
be  hereafter  described.  Of  course  the  sub-peat  then  become  a  variety 
of  these.  Deposits  of  this  character  are  extremely  common  in  this 
country,  as  well  as  elsewhere,  and  it  will  be  at  once  seen  that,  although 


NATURAL   HISTORY   OF   THE   DIATOMACE^E.  46$ 

any  one  of  them  might  be  of  great  thickness,  yet  it  does  not  necessarily 
follow  that  it  had  been  forming  for  any  great  number  of  years;  and 
geologists  and  others  are  not  warranted,  from  observance  of  this  one 
fact  of  thickness,  in  supposing  that  a  great  length  of  time  has  inter 
vened  during  its  deposition.  Thus,  some  years  since,  I  examined  one 
of  these  lacustrine  sedimentary  deposits,  at  a  spot  near  the  town  of  East 
Stoughton  in  Massachusetts,  which  was  fully  twelve  feet  thick,  but  only 
covered  a  few  feet  of  surface,  which  circumstance  was  due  to  the  occur 
rence  of  a  dam  across  the  course  of  a  stream,  which  arrested  its  progress 
and  formed  a  small,  deep  pond,  into  which  all  of  the  diatomaceas,  which 
grew  for  some  considerable  distance  up  stream,  drained,  and,  dying, 
accumulated  as  a  light  grey-colored  powder.  I  have  received  specimens 
of  similar  material  from  many  points  in  this  country,  so  that  about  one 
hundred  have  been  examined.  The  state  of  New  Hampshire  has  sup 
plied  quite  a  number,  and  they  will  be  hereafter  described,  and  the 
forms  detected  in  them  illustrated. 

The  first  recorded  discovery  of  a  lacustrine  sedimentary  deposit  of 
diatomaceae  in  this  country  is  found  in  Sillimans  Journal,  1839,  vo^ 
xxv,  p.  1 1 8,  in  an  article  "On  Fossil  Infusoria  discovered  in  Peat-earth 
at  West  Point,  N.  Y.,  with  some  notices  of  American  species  of  Dia- 
tomae.  By  J.  W.  Bailey."  Of  this  I  have  a  small  portion  given  me  by 
Prof.  Bailey  himself,  and,  on  examination,  it  is  found  to  have  the  general 
characteristics  of  these  deposits ;  that  is  to  say,  it  is  of  a  grey  color, 
light  in  density  and  very  friable,  and  is  made  up  of  the  siliceous  skele 
tons  of  such  species  of  diatomaceas  as  grow  in  small  fresh-water  lakes, 
ponds,  and  marshes.  In  fact,  Prof.  Bailey  says  that  this  deposit,  which 
was  "eight  or  ten  inches  thick,  and  probably  several  hundred  square 
yards  in  extent,"  was  discovered  "about  a  foot  below  the  surface  of  a 
small  peat-bog  immediately  at  the  foot  of  the  southern  escarpment  of 
the  hill  on  which  the  celebrated  Fort  Putnam  stands."  He  considers 
the  remains  present  in  this  stratum  to  be  "in  a  fossil  state."  And  here, 
perhaps,  it  is  desirable  to  say  something  with  regard  to  the  use  of  this 
term.  Its  origin  would  warrant  its  being  applied  to  anything  dug  up  out 
of  the  earth;  and,  as  Mr.  Page  remarks  in  his  Handbook  of  Geological 
Terms,  "hence  the  earlier  geologists  spoke  of  native  fossils  or  minerals, 
and  extraneous  fossils,  or  the  bodies  of  plants  and  animals  accidentally 
VOL.  i.  6 1 


466  PHYSICAL    GEOGRAPHY. 

buried  in  the  earth."  For  myself,  I  am  disposed  to  restrict  the  term 
fossil  to  the  remains,  more  or  less  perfect,  of  organized  beings  dating 
anterior  to  the  present  epoch,  if  we  can  conscientiously  speak  of  epochs 
at  all  where  the  progression  and  rate  of  change  have  been  so  gradual. 
Considered  thus,  then,  these  remains  of  diatomaceae  cannot  be  classed 
as  fossils ;  and  at  once  the  geologist  perceives  that  they  are  to  be  taken 
into  account  in  a  very  different  manner  from  what  they  have  been  hith 
erto.  So  much,  then,  for  lacustrine  sedimentary  deposits  of  diatomacece ; 
and  I  trust  that  I  have  made  clear  as  to  what  they  are,  and  how  they  are 
formed  and  forming.  At  the  time  I  made  his  acquaintance,  Prof.  Bailey 
expressed  an  opinion  that  similar  strata  would  be  found  beneath  every 
bog  and  pond  in  the  country.  The  clear  scientific  vision  of  my  late 
friend  is  evidenced  in  the  fact  that  this  prediction  was  proved  almost  lit 
erally  true.  I  have  over  one  hundred  such  specimens,  and  am  continually 
receiving  others.  Several  I  have  already  described,  and  others  remain  to 
be  examined,  and  facts  with  regard  to  the  geographical  distribution  and 
other  points  will  be  elucidated  by  such  investigations, — so  that  I  am 
always  anxious  to  receive  contributions  from  all  sources.  It  is  only 
desirable  that  all  facts  connected  with  their  mode  of  occurrence,  as  to 
amount  in  thickness  and  extent,  over-  and  underlying  material,  etc.,  be 
noted  at  the  time  of  making  the  gathering. 

We  now  come  to  consider  deposits  of  an  entirely  different  character 
from  those  just  spoken  of,  but  which  yet  are  also  made  up  almost  en 
tirely  of  the  siliceous  remains  of  fresh-water  diatomaceae.  These  are 
the  so-called  "infusorial"  deposits  found  in  such  enormous  quantity  in 
our  Pacific  states.  From  time  to  time,  during  the  last  thirty  years,  spec 
imens  of  these  have  come  into  the  hands  of  naturalists,  from  collectors 
and  otherwise,  and  also  "in  place"  they  are  well  known  to  settlers  in  the 
districts  where  they  occur.  As  their  true  character  has  not  been  under 
stood,  they  have  received  various  appellations,  as  "magnesia,"  "porcelain 
clay,"  "white  clay,"  "chalk,"  "siliceous  marl,"  "microphytal  earth,"  "trip- 
oli,"  "rotten-stone,"  "pipe-clay"  or  simply  "clay,"  "trachytal  tufa,"  and 
"phytolitharian  tuff,"  by  Ehrenberg.  These  specimens  are  almost  always 
white  in  color,  or  nearly  so,  although  there  are  records  of  some  strata 
occurring  of  various  tints.  None  of  these  except  the  white  ones  have 
come  under  my  observation,  so  I  am  not  prepared  to  state  that  the 


NATURAL    HISTORY    OF    THE    DIATOMACE^.  467 

colored  ones  are  diatomaceous.  Besides,  this  material  is  of  a  somewhat 
hard,  stony  character,  but  porous  withal,  and  light;  as  a  general  thing, 
also,  it  is  readily  broken,  but  not  easily  powdered,  as  are  the  lacustrine 
sedimentary  deposits.  On  account  of  this  hardness  there  is  found  to  be 
considerable  difficulty  in  preparing  these  specimens  for  microscopical 
examination.  After  so  preparing,  by  a  method  I  have  devised,  to  be 
described  hereafter,  and  viewing  with  a  sufficiently  high  magnifying  lens, 
this  substance  is  found  to  be  made  up  entirely  of  the  siliceous  remains 
of  fresh- water  diatomaceae  which  have  been  matted  together  in  the  re 
markable  manner  described.  The  species  of  diatomaceae  present,  how 
ever,  are  found  to  be  very  different  in  character  from  those  to  be  seen  in 
the  other  class  of  recently  formed  deposits.  Thus,  while  the  genera 
most  commonly  represented  in  and  making  up  the  mass  of  the  lacustrine 
sedimentary  deposits  are  Navicula,  Pinnularia,  Staiironeis,  Synedra,  and 
similar  elongated  forms,  the  hard,  white  material  is  in  general  found  to 
consist  of  myriads  of  examples  of  Orthosira,  Cyclotella,  and  similar  dis 
coid  forms.  Although  our  knowledge  of  the  forms  of  these  minute 
organisms,  peculiar  to  different  kinds  of  collections  of  water,  is  rather 
imperfect,  yet  we  know  that  the  naviculaeform  genera  spoken  of  above 
are  found  in  small  lakes,  while  in  the  larger  pieces  of  water  are  to  be 
seen  growing  more  particularly  the  discoid  genera  like  Cyclotclla.  From 
this  fact  alone,  then,  we  should  be  prepared  to  assume  that  the  waters, 
in  which  the  organisms  whose  remains  make  up  these  deposits  grew  at 
one  time,  covered  large  tracts  of  country.  And  our  surmises  on  this 
point  are  confirmed  by  the  reports  of  explorers  who  have  passed  over, 
this  section  of  country,  that  is  to  say,  on  both  sides  of  the  Sierra  Ne 
vada  Mountains,  from  Puget's  sound  to  the  southernmost  border  of 
California,  for  they  tell  us  that  these  deposits  extend  over  a  consider 
able  portion  of  the  Pacific  states. 

I  have  examined  many  specimens  from  this  district,  and,  on  account 
of  the  mode  of  occurrence  of  this  material,  being  capped  by  lava,  basalt, 
or  some  volcanically-erupted  rock,  I  have  designated  them  sub-plutonic. 
The  first  specimens  of  such  sub-plutonic  deposits  of  diatomaceae,  which 
were  put  into  the  hands  of  scientists,  were  undoubtedly  those  brought 
home  by  Fremont,  from  his  expeditions  to  the  Rocky  Mountains,  in 
the  year  1842,  and  to  Oregon  and  North  California,  in  the  years  1843 


468  PHYSICAL    GEOGRAPHY. 

and  1844.  The  discovery  of  these,  as  detailed  in  his  report,  gives  a 
good  idea  of  this  portion  of  the  country,  and  is  as  follows.  It  must  be 
premised  that,  in  that  report,  what  is  now  known  as  the  Des  Chutes 
river,  and  which  is  one  of  the  tributaries  of  the  Columbia,  is  called 
"Fall  river"  (Rivttrc  aux  Chutes);  so,  also,  he  spells  Klamath  lake 
"Tlamatt."  Speaking  of  the  tributaries  of  the  Columbia  river,  he  says 
(p.  200),— 

These  streams  are  characterized  by  the  narrow  and  chasm-like  valleys  in  which  they 
run,  generally  sunk  a  thousand  feet  below  the  plain.  At  the  verge  of  this  plain  they 
frequently  commence  in  vertical  precipices  of  basaltic  rock,  and  which  leave  only 
casual  places  at  which  they  can  be  entered  by  horses.  The  road  across  the  country, 
which  would  otherwise  be  very  good,  is  rendered  impracticable  for  wagons  by  these 
streams.  At  such  places  the  gun-carriage  was  unlimbered,  and  separately  descended 
by  hand.  Continuing  a  few  miles  up  the  left  bank  of  the  river,  we  encamped  early  in 
an  open  bottom  among  the  pines,  a  short  distance  below  a  lodge  of  Indians.  Here, 
along  the  river  bluffs  present,  escarpments  seven  or  eight  hundred  feet  in  height,  con 
taining  strata  of  a  very  fine  porcelain  clay,  overlaid,  at  the  height  of  about  five  hundred 
feet,  by  a  massive  stratum  of  basalt  one  hundred  feet  in  thickness,  which  again  is  suc 
ceeded  above  by  other  strata  of  volcanic  rocks.  The  clay  strata  are  variously  colored, 
some  of  them  very  nearly  as  white  as  chalk,  and  very  fine  grained.  Specimens 
brought  from  there  have  been  subjected  to  microscopical  examination  by  Prof.  Bailey, 
of  West  Point,  and  are  considered  by  him  to  constitute  one  of  the  most  remarkable 
deposits  of  fluviatile  infusoria  on  record.  While  they  abound  in  genera  and  species 
which  are  common  in  fresh  water,  but  which  rarely  thrive  where  the  water  is  brackish, 
not  one  decidedly  marine  form  is  to  be  found  among  them ;  and  their  fresh-water 
origin  is  therefore  beyond  a  doubt.  It  is  equally  certain  that  they  lived  and  died  in 
the  situation  where  they  were  found,  as  they  could  scarcely  have  been  transported  by 
running  waters  without  an  admixture  of  muddy  particles,  from  which,  however,  they 
are  remarkably  free.  Fossil  infusoria  of  a  fresh-water  origin  had  been  previously  de 
tected  by  Mr.  Bailey  in  specimens  brought  by  Mr.  James  D.  Dana  from  the  tertiary 
formation  of  Oregon.  Most  of  the  species  in  those  specimens  differed  so  much  from 
those  now  living  and  known,  that  he  was  led  to  infer  that  they  might  belong  to  extinct 
species,  and  considered  them  also  as  affording  proof  of  an  alternation,  in  the  forma 
tion  from  which  they  were  obtained,  of  fresh-  and  salt-water  deposits,  which,  common 
enough  in  Europe,  had  not  hitherto  been  noticed  in  the  United  States.  Coming  evi 
dently  from  a  locality  entirely  different,  our  specimens  show  very  few  species  in  com 
mon  with  those  brought  by  Mr.  Dana,  but  bear  a  much  closer  resemblance  to  those 
inhabiting  the  north-eastern  states.  It  is  possible  that  they  are  from  a  more  recent 
deposit ;  but  the  presence  of  a  few  remarkable  forms,  which  are  common  to  the  two 
localities,  renders  it  more  probable  that  there  is  no  great  difference  in  their  ages. 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  469 

I  have  given  in  full  all  that  Fremont  says  regarding  this  locality,  as  it 
presents  us  with  the  first  discovery  of  strata  of  the  remarkable  character 
of  which  I  am  now  treating,  and  is  therefore  of  special  interest.  Bailey's 
report,  contained  in  the  same  volume,  merely  mentions  and  figures  the 
principal  forms  he  detected. 

The  only  other  description  of  this  locality  and  these  remarkable 
deposits,  fortunately,  is  a  much  more  complete  and  scientific  one.  It  is 
that  of  Dr.  J.  S.  Newberry,  as  geologist  of  the  expedition  under  Lieuts. 
R.  S.  Williamson  and  Henry  L.  Abbot,  which  explored  the  route  for  a 
railroad,  from  the  Sacramento  valley  to  the  Columbia  river,  in  1855, 
and  will  be  found  in  vol.  vi  of  the  Pacific  Railroad  Survey  Report.  Dr. 
Newberry  gives  a  description  of  the  geology  of  the  Des  Chutes  basin, 
which  is  essentially  as  follows.  It  must  be  remembered  that  the  Des 
Chutes  and  Fall  river,  mentioned  above,  are  one  and  the  same.  The 
Des  Chutes  basin  consists  of  a  series  of  plateaus,  having  varying  eleva 
tions  from  four  thousand  to  twenty-two  thousand  feet  above  the  level  of 
the  sea,  separated  by  subordinate  ranges  of  volcanic  mountains.  These 
plateaus  are  usually  covered  by  a  floor  of  trap,  which  extends  in  a 
smooth  sheet  from  fifty  to  a  hundred  and  fifty  feet  in  thickness,  un 
broken  except  by  and  at  the  canons  of  the  various  streams  which,  as  a 
general  thing,  flow  from  the  interior  to  the  ocean  at  right  angles  to  the 
coast  line.  Beneath  this  bed  of  trap  is  the  whitish  or  light-colored 
material,  consisting  of  the  siliceous  remains  of  diatomaceae  we  are  con 
sidering,  sometimes  occurring  as  a  single  bed  only,  sometimes  as  a  series 
of  beds  locally  intercalated  with  thin  beds  of  trap.  These  infusorial 
strata,  as  they  have  been  called,  are  cut  in  many  places  by  the  Des 
Chutes  and  its  tributaries  to  the  depth  of  more  than  a  thousand  feet, 
without  exposing  the  basis  on  which  they  rest.  They  are  usually  quite 
horizontal,  from  a  few  lines  to  twenty  feet  in  thickness,  and  very  accu 
rately  stratified. 

Psuc-see-que  creek,  one  of  the  tributaries  of  the  Des  Chutes  river, 
flows  through  a  valley  of  a  remarkable  character,  as  its  sides  consist  of 
several  alternate  strata  of  diatomaceous  material  and  columnar  trap  or 
concrete.  Near  the  base  of  this  series  of  layers  is  a  stratum,  three  feet 
in  thickness,  of  brilliant  white  feldspathic  pumice,  so  soft  as  to  be  easily 
crumbled  in  the  fingers.  Above,  and  lying  upon  this,  is  a  line  of  dark

carbonaceous  matter,  less  than  a  quarter  of  an  inch  in  thickness,  from 
which,  up  into  another  layer  of  pumice,  projects  the  remains  of  the 
branches  of  some  small  plant  which  had  apparently  been  killed  by  the 
overflow  of  the  pumice.  Lieut.  Williamson  gives  a  striking  view  of  this 
locality,  and  speaks  of  it  in  the  following  terms: 

This  river  canon  is  very  remarkable.  Its  sides  vary  from  eight  hundred  to  two  thou 
sand  feet  in  height.  The  river  has  cut  down  its  bed  to  this  immense  depth  through 
successive  strata  of  basalt,  with  occasionally  a  deposit  of  infusorial  marl  and  volcanic 
tufa,  which  has  sometimes  hardened  into  a  kind  of  conglomerate  sandstone  ten  or 
twenty  feet  in  thickness,  and  of  a  white,  grey,  or  reddish  color.  We  followed  down 
this  cafion  for  about  five  miles,  when  a  rocky  spur  cut  off  all  further  progress,  and 
compelled  us  to  attempt  the  ascent.  This  with  great  difficulty  we  accomplished,  and 
found  ourselves  on  a  plain  thinly  dotted  with  sage  bushes  and  clumps  of  grass.  We 
continued  our  course,  and,  after  crossing  the  bed  of  a  torrent  of  the  rainy  season, 
came  to  a  very  small  stream,  called  Psuc-see-que  by  the  Indians.  It  was  sunk  in  a 
canon  about  five  hundred  feet  deep,  cut  through  successive  strata  of  basalt,  infusorial 
marl,  tufas,  and  conglomerate  sandstone  like  that  found  in  the  Mpto-ly-as  canon  (pp. 
84,85). 

Another  locality  in  which  these  remarkable  deposits  occur  is  on  the 
Pitt  river;  and  Lieut.  Williamson's  description  gives  such  a  good  idea 
of  the  mode  of  their  occurrence  that  I  transcribe  it,  also,  below: 

The  banks  of  the  Pitt  river,  both  above  and  below  the  mouth  of  Canoe  creek,  are 
partially  formed  by  regularly  stratified  sedimentary  deposits,  the  first  seen  since  leav 
ing  the  valley  of  the  Sacramento.  They  appear  on  both  sides  of  Pitt  river  at  intervals 
for  several  miles,  being  in  many  places  interrupted  or  covered  by  beds  of  trap.  They 
are,  perhaps,  best  exposed  in  the  cafion  formed  by  the  passage  of  the  river  through 
"  Stoneman's  ridge,"  the  most  conspicuous  of  the  lines  of  upheaval  which  form  what 
is  known  as  the  lower  cafion  of  Pitt  river.  They  here  exhibit  a  thickness  of  about 
fifty  feet,  but  are  considerably  tilted  up,  and  are  covered  by  a  thick  bed  of  trap  which 
has  been  poured  out  over  them.  They  exhibit  narrow  and  parallel  lines  of  deposition, 
but  are  very  homogeneous,  and  can  hardly  be  said  to  form  more  than  two  distinct 
beds.  Of  these,  the  upper  is  white,  resembling  very  pure  kaolin,  derived  from  the 
decomposition  of  crystalline  feldspar.  The  lower  bed  is  light  brown  or  dirty  white  in 
color,  and  has  a  slightly  gritty  feel  between  the  fingers.  These  strata  rest  upon  a 
thick  bed  of  rolled  and  rounded  fragments  of  traps,  porphyry,  and  basalt  of  all  sizes, 
from  masses  of  two  and  even  three  feet  in  diameter,  to  pebbles.  They  are  generally 
as  large  as  one's  head,  and  great  numbers  are  each  a  foot  in  diameter.  The  surface 
of  this  bed  of  boulders  is  perhaps  twenty  feet  above  the  present  surface  of  the  stream  ; 
but  it  bears  indubitable  evidence  of  having  at  one  time  been  covered  by  it,  or,  at  least, 


NATURAL    HISTORY    OF    THE    DIATOMACE^E. 

the  stones  composing  it,  so  large  and  clear,  have  been  rounded  where  they  lie  by  a 
current  or  waves  of  water.  The  appearance  presented  by  this  bed  of  boulders  is  dif 
ferent  from  that  of  any  of  the  beds  of  volcanic  conglomerate  which  are  so  common  in 
many  parts  of  California  and  Oregon,  or  of  the  stratified  conglomerates  of  the  Sacra 
mento  valley,  and  it  is  undoubtedly  of  local  origin.  The  trap  which  formed  the 
greater  part  of  the  bank  above  is  evidently  of  recent  date,  more  recent  than  the  infu 
sorial  marls,  and  the  marls  more  recent  than  the  conglomerate,  and  the  conglomerate 
an  accumulation  of  rolled  stones  and  pebbles,  which  belongs  to  the  present  epoch. 
The  trap  which  overlies  the  infusorial  marls  composes  a  large  part  of  the  walls  of  the 
canon  at  this  point,  where  it  has  been  cut  away  by  the  stream,  and  forms  nearly  per 
pendicular  faces  of  several  hundred  feet  in  height.  The  soft  nature  of  the  underlying 
strata  has,  however,  very  much  assisted  in  its  removal  (p.  33) . 

There  are  several  localities  besides  those  mentioned  at  which  this, — 
what  I  have  chosen  to  designate  "sub-plutonic," — material  is  found,  as 
at  Klamath  lake,  on  the  northern  border  of  California,  and  elsewhere  all 
through  the  Pacific  states.  From  these  I  have  received  gatherings,  and 
have  thus  been  enabled  to  examine,  by  means  of  the  microscope,  spec 
imens  from  many  points  in  what  was  once  this  chain  of  enormous 
fresh-water  inland  seas, — for  such  they  deserve  to  be  styled.  For  as  the 
microscope  reveals  the  fact,  the  organisms,  whose  stony  remains  consti 
tute  the  mass  of  these  deposits,  were  inhabitants  of  collections  of  fresh 
water  which  existed  at  some  past  period  as  large  lakes;  and  a  careful 
geographical  examination  of  the  country  enables  us  even  to  indicate,  to 
a  certain  extent,  the  situations  once  occupied  by  these  now  extinct  seas, 
which  at  times  varied  in  superficial  dimensions,  and  certainly  were  in 
some  cases  drained,  overflowed  by  lava,  and  renewed  and  replenished 
with  living  organisms  as  many  as  seven  times. 

And  now  that  we  understand  how  it  is  that  lacustrine  sedimentary 
deposits  are  formed  by  the  accumulation  of  the  dead  shells  of  diato- 
macese,  we  can  comprehend  the  manner  in  which  these  sub-plutonic 
strata  have  been  laid  down.  If  we  look  at  the  map  of  the  western 
coast  of  the  North  American  continent,  we  see  that  there  are  three 
great  chains  of  mountains,  about  parallel  to  each  other  and  the  coast 
line,  and  thus  enclosing  between  their  peaks  two  long  and  wide  valleys. 
The  Rocky  Mountains  are  the  first  of  these  chains,  and  they  at  one 
time  formed  the  coast  of  this  continent.  Slowly  and  gradually,  however, 
there  appeared  a  line  of  islands  at  a  distance  from  the  coast,  whose 


472  PHYSICAL   GEOGRAPHY. 

material  was  volcanic,  and,  as  these  islands  rose  higher  and  higher,  the 
space  between  them  and  the  coast  cliffs  also  rose  until  it  became  dry 
land.  Soon  rain  fell  and  accumulated  in  this  valley  so  formed,  and  lakes 
and  rivers  appeared.  In  these,  diatomaceae  appeared,  thrived,  grew, 
reproduced,  and  multiplied ;  lacustrine  sedimentary  deposits  were  thrown 
down.  Now  came  a  time  when  the  volcanic  cones,  which  constituted  the 
peaks  of  the  range  of  mountains  nearest  to  the  coast,  burst  forth  with  fire 
and  lava ;  and,  probably  at  the  same  time,  earthquakes  took  place  which 
drained  many  of  the  lakes  and  changed  the  courses  of  rivers.  Into  the 
lake  basins  the  lava  was  poured,  with  its  heat  evaporating  the  moisture, 
and  consolidating  the  diatomaceous  material  into  a  stony  mass,  from 
which  all  organic  matter  was  burned  out.  A  period  of  rest  succeeded. 
Diatoms  again  appeared  and  accumulated,  to  be  again  overlaid  by  lava ; 
and  so  on  the  same  thing  may  have  again  and  again  taken  place.  In 
this  way  the  enormous  deposits  of  sub-plutonic  diatomacese  were  formed ; 
and  in  the  cracks,  made  in  the  rock  by  volcanic  agency,  the  rivers 
wended  their  way,  and  made  the  gates  we  now  are  in  the  habit  of  call 
ing  canons. 

But  in  the  ocean  diatomaceae  also  occur,  and  in  large  quantities. 
When  they  die  there,  their  siliceous  remains  must  accumulate  at  the 
bottom  of  the  water,  and  occur  as  deposits.  It  is  in  the  black  mud  of 
our  quiet  bays  and  harbors  that  we  must  look  for  the  greatest  accumu 
lation  of  these  remains ;  and  rivers  are  carrying  them  down  to  their 
mouths,  where  often  they  are  piled  up  in  such  masses  as  to  form  bars. 
The  mud  of  the  river  Thames  in  England  yielded  to  Mr.  Roper  a  large 
number  of  diatomaceous  remains.  Ehrenberg  examined  the  mud  of  the 
Elbe  in  Germany,  and  found  these  minute  shells  to  make  up  from  one 
quarter  to  one  third  of  the  whole  mass.  He  calculated  that  at  Pillau 
there  are  annually  deposited  from  the  water  from  seven  thousand  two 
hundred  to  fourteen  thousand  cubic  metres  of  these  minute  shells, 
which  in  the  course  of  a  century  would  give  a  deposit  of  from  seven 
hundred  and  twenty  thousand  to  one  million  four  hundred  thousand 
cubic  metres  of  deposit,  which  might  be  hardened  into  a  stony  mass. 
That  such  hardening  has  taken  place  is  evidenced  by  the  occurrence  of 
the  vast  strata  of  marine  forms  found  in  Virginia  and  Maryland,  on  the 
Atlantic  side  of  North  America,  and  in  California  on  the  Pacific  coast. 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  4/3 

This  material  is  often  almost  white,  but  more  commonly  is  tinted  slightly 
yellowish  or  salmon-colored.  It  makes  up  the  most  part  of  the  material 
of  the  coast  range  of  mountains  in  California,  and  has  also  been  found 
in  Peru,  Japan,  Algeria,  Spain,  and  the  West  India  islands.  In  Cali 
fornia,  in  the  almost  rainless  districts,  it  is  used  for  building,  but  gen 
erally  is  too  friable  for  that  purpose.  The  forms  occurring  in  it  are  for 
the  most  part  discoid,  with  a  few  triangular  ones,  and,  when  prepared 
and  examined  by  means  of  the  microscope,  present  one  of  the  most 
beautiful  objects  which  can  be  so  viewed. 

Something  has  been  said  with  regard  to  the  origin  of  the  substance 
known  as  guano,  and  which  has  been  so  extensively  used  as  a  fertilizer; — 
but  to  the  agricultural  fraternity  anything  connected  with  this  material 
must  prove  of  interest,  so  it  is  thought  best  to  enter  more  fully  into  the 
consideration  of  this  subject  on  account  of  its  important  bearings,  its 
value  to  geologists,  and  its  general  attraction,  evinced  by  the  manner  in 
which  the  publications  of  the  present  writer  thereon  have  been  copied 
and  circulated  by  the  periodical  press. 

On  May  i,  1871,  a  discussion  took  place  at  the  Lyceum  of  Natural 
History,  New  York,  on  the  subject  of  guano,  when  the  Hon.  E.  G. 
Squier  exhibited  a  map  of  the  Guanape  islands  of  Peru,  where  guano 
is  found,  drawings  of  a  wooden  idol  and  other  objects  discovered  in  the 
guano,  and  photographs  showing  that  that  substance  is  distinctly  strati 
fied,  and  not  thrown  clown  in  the  shape  of  a  confused  mass,  as  would  be 
the  case  if  it  were,  as  is  usually  supposed,  merely  the  excrement  of 
birds  and  other  animals  deposited  on  rocky  islands,  in  localities  where 
little  or  no  rain  falls  to  wash  out  its  soluble  and  valuable  constituents. 

Dr.  A.  Habel,  who  had  visited  the  Chincha  islands  for  the  purpose 
of  studying  the  mode  of  occurrence  of  the  guano  (or,  as  he  prefers  to 
write  it,  in  consonance  with  the  mode  of  its  pronunciation,  "whuano"), 
made  an  extended  communication  showing  that  the  outer  and  uppermost 
portion  of  this  substance  does  consist  of  the  droppings  of  various  spe 
cies  of  sea-birds  and  mammals,  mixed  with  the  feathers  and  eggs  of  birds, 
and  bones.  This  layer  does  not  at  all  show  signs  of  stratification,  and  is 
of  a  reddish  brown  color.  Below  this  is  the  guano  proper,  which  is  of  a 
different  structure,  and  distinctly  stratified.  He  says  that  "this  stratifi 
cation  is  so  marked  that  even  a  superficial  examination  must  convince 
VOL.  i.  62 


474  PHYSICAL    GEOGRAPHY. 

every  unprejudiced  person  that  it  is  the  product  of  sedimentary  for 
mation.  It  is  made  up  of  alternate  white  and  yellow  strata,  varying 
in  shade  and  thickness.  All  of  these  strata  exhibit  distinctly  their 
inclination  or  dip,  which  varies  not  only  on  the  separate  islands,  but  in 
different  parts  of  the  same  island.  On  the  middle  island,  for  example, 
the  inclination  or  dip  of  the  strata  in  one  part  of  it  does  not  amount  to 
more  than  five  degrees,  while  in  another  part  it  is  eight  degrees,  and  in 
a  third,  close  to  the  first,  fifteen  degrees."  In  one  place  strata,  running 
south-west  and  north-east,  and  dipping  twenty  degrees,  rested  uncon- 
formably  on  others  running  north  and  south,  and  dipping  only  four 
degrees.  In  all  of  the  strata  are  imbedded  stones  of  various  sizes  and 
weight  up  to  fifteen  pounds,  as  well  as  eggs  and  bones.  Another  proof 
that  the  guano  has  been  deposited  beneath  the  ocean  is  seen  in  the 
various  strata  of  sea  sand  underlying  it,  and  which  are  also  stratified,  and 
dip  in  one  direction  or  the  other. 

The  present  writer  said  that  he  first  made  his  hypothesis  public,  with 
regard  to  guano  having  been  deposited  beneath  the  water  of  the  ocean, 
in  1868,  at  a  meeting  of  the  American  Microscopical  Society.  In  Jan 
uary,  1869,  he  entered  more  fully  into  a  discussion  of  the  subject  before 
the  Essex  Institute,  at  Salem,  Mass.  He  said, — 

I  have  been  for  the  last  fifteen  years  or  more  studying  the  so-called  "infusorial 
deposits "  of  marine  origin.  Among  the  specimens  thus  examined  are  some  of  the 
rocks  or  shales  making  up  the  great  mass  of  the  mountains  of  the  coast  range,  which 
extend  down  the  Pacific  shore  from  Washington  territory  to  the  borders  of  Lower 
California,  and  even  perhaps  down  as  far  as  the  southernmost  extremity  of  that  penin 
sula.  These  shales  are  usually  of  a  light  cream  color,  and  mainly  consist  of  the 
siliceous  skeletons  of  diatomaceae  and  polycystina,  the  former  being  commonly  con 
sidered  as  plants,  the  latter  as  animals.  These  are  of  extremely  minute  size,  and 
often  require  for  their  study  the  use  of  the  highest  magnifying  powers.  Many  of  them 
prove  to  be  indistinguishable  from  forms  living  at  the  present  day  on  the  California 
coast.  Exuding  through,  and  often  appearing  at  the  upper  portion  of  these  rocks,  to 
which  situation  they  have  evidently  been  driven  by  heat,  are  found  the  petroleum,  bitu 
men,  and  asphalt  of  California.  Hence  the  state  survey  has  conferred  upon  these  strata 
the  name  of  bituminous  shales.  Along  the  Pacific  coast,  and  lying  parallel  to  it,  are 
islands  often  bearing  upon  their  summits  deposits  of  guano,  of  more  or  less  commercial 
value.  In  many  cases  the  quantity  has  been  small  and  soon  removed ;  but  I  am  in 
formed  that  there  are  deposits  of  this  material  in  that  quarter  of  the  globe  still 
unworked.  At  the  same  time,  it  must  be  remembered  that  the  whole  Pacific  coast,  of 


NATURAL    HISTORY    OF    THE    DIATOMACEyE.  4/5 

both  North  and  South  America,  is  in  an  almost  continual  state  of  motion,  and  gradual 
but  constant  upheaval,  caused,  doubtless,  by  the  action  of  internal  chemical  changes, 
which  make  themselves  markedly  evident  in  the  volcanic  vents  found  all  along  the 
mountains  constituting  the  Cascades  and  Sierra  Nevadas  of  North,  and  the  Ancles  of 
South  America.  There  have  been  identified  at  least  three  former  lines  of  rise  of  coast, 
and  still  another  is  seen  presenting  its  peaks  in  the  islands,  which  will,  at  some  future 
day,  be  united  in  such  a  manner  as  to  constitute  another  coast  range  of  mountains. 

If,  now,  we  consider  the  bearing  of  these  facts  on  the  origin  of  the  substance  known 
as  guano,  we  find  the  following  points  worthy  of  note.  Guano  may  be  divided  into 
two  great  groups,  the  ammoniacal  and  the  phosphatic ;  but  it  is  of  the  first  mentioned, 
only,  that  I  desire  to  treat  at  the  present  time,  and  to  which  I  wish  to  apply  my  de 
ductions.  Guano  is  usually  considered  as  the  excrement  of  sea-fowl,  and  which  has 
accumulated  during  a  long  period  of  time, — so  long,  that  attempts  have  been  made  to 
calculate  its  age  from  its  thickness.  Thus  Humboldt,  who  first  made  this  substance 
known  to  the  Eastern  hemisphere  in  1804,  states,  that  on  the  Chincha  islands  it  has  a 
depth  of  fifty  to  sixty  feet,  and  that  the  accumulation  of  the  preceding  three  hundred 
years  has  formed  only  a  few  lines  of  this  thickness.  The  facts  brought  forward  by  Mr. 
Squier  show  how  difficult  it  is  to  arrive  at  any  certain  knowledge  on  this  point,  and,  in 
fact,  show  that  we  have  no  means  of  ascertaining  the  age  of  the  guano  deposits,  even 
if  we  accept  the  theory  of  their  origin  from  the  source  usually  ascribed  to  them.  We 
find  that  guano  is  not  confined  to  islands  only,  but  occurs  in  large  quantities  on  the 
contiguous  headlands  ;  and  many  ravines,  extending  into  the  interior  of  the  country, 
contain  guano  in  smaller  and  larger  quantities.  Thus,  the  ravines  of  Lolo,  Culata, 
Sacramento,  Animas,  Morillo,  Guajes,  Colorado,  Chucumata,  and  Pica  are  reported  to 
contain  pure  guano  deposits,  covered  by  a  thick  coating  of  sand.  Neither  is  it  found 
in  rainless  districts  only,  for,  as  I  have  said,  it  is  found  on  the  islands  off  the  Califor 
nia  coast,  which  are  by  no  means  rainless ;  and  Mr.  W.  H.  Dall  informs  me  that  it 
occurs  on  the  Aleutian  islands,  where  the  air  is  almost  always  saturated  with  moisture, 
and  heavy  rains  fall  during  a  large  part  of  the  year.  With  regard  to  the  upheaval  of 
such  coasts  along  which  guano  occurs,  it  is  well  known,  from  Darwin's  investigations, 
that  the  whole  Pacific  coast  of  South  America  is  in  constant  motion  and  upheaval,  and 
that  on  the  main  land  near  Lima,  and  on  the  adjoining  island  of  San  Lorenzo,  Mr. 
Darwin  found  proofs  that  the  ancient  bed  of  the  sea  had  been  raised  to  the  height  of 
more  than  eighty  feet  above  the  water,  within  the  human  epoch,  strata  having  been 
discovered  at  that  altitude  containing  pieces  of  cotton  thread  and  plaited  rush,  together 
with  sea-weed  and  marine  shells  (Lyell,  Principles,  1853,  p.  502). 

And  Darwin  says, — "I  have  convincing  proofs  that  this  part  of  the  continent  of 
South  America  has  been  elevated  near  the  coast  at  least  from  three  hundred  to  five 
hundred  feet,  and,  in  some  parts,  one  thousand  to  thirteen  hundred  feet,  since  the 
epoch  of  existing  shells."  Other  proofs  of  this  fact  are  not  wanting,  but  these  are 
sufficient  for  me  to  quote  at  the  present  time. 

When  the  portions  of  guano,  which  are  insoluble  in  water  and  acids,  are  examined 


4/6  PHYSICAL    GEOGRAPHY. 

by  means  of  the  microscope,  they  are  found  to  be  made  up  of  the  skeletons  of  diato- 
macere,  polycystina,  and  sponges,  invariably  of  marine  origin,  and  sometimes  identical 
with  those  living  in  the  adjoining  ocean,  and  fossilized  in  the  adjacent  infusorial  strata. 
Also,  we  find  that  some  of  these  forms  occur  in  patches  exactly  as  they  grow  in  nature, 
and  as  they  would  present  themselves  if  they  were  deposited  from  water,  and  not  as 
they  would  be  if  they  had  to  pass  first  through  the  alimentary  canals  of  mollusca  and 
similar  small  animals,  then  through  the  same  organs  of  fish  and  birds,  in  turn,  as  they 
would  have  to  do  to  get  into  the  guano  in  the  manner  commonly  supposed. 

In  California  we  have  a  deposit  of  "infusoria,"  improperly  so  called,  accompanied 
by  bitumen,  which  bitumen,  the  gentlemen  of  the  state  survey  believe,  has  been 
derived  from  those  "infusoria,"  and  that  contiguous  thereto  we  have  guano  deposits. 
Now  let  us  see  if  we  have  a  similar  association  of  facts  anywhere  else.  At  Payta,  in 
Peru,  Dr.  C.  F.  Winslow  discovered  an  "infusorial"  deposit  almost  identical  in  char 
acter  with  the  California  one.  Near  by  are  bitumen  springs ;  and  lying  off  the  coast 
are  the  guano  islands  of  Lobos,  Chincha,  Guanape,  and  others.  At  Netanai,  Japan, 
we  have  extensive  "infusorial"  strata  and  bitumen;  it  is  not  recorded  whether  guano 
occurs  in  that  quarter.  In  the  island  of  Barbadoes  we  have  "infusorial"  strata,  bitu 
men,  and,  near  by,  the  guano  islands  of  the  Carribean  sea ;  and,  I  am  informed,  guano 
is  abundant  on  the  small  islands  and  rocks  nearly  throughout  the  West  Indian  archi 
pelago.  In  the  island  of  Trinidad  we  have  "infusorial"  strata  and  bitumen,  and,  of 
course,  adjacent  guano.  At  all  of  these  localities  volcanic  action  is  evident ;  but  we 
have  some  localities  of  guano  without  "infusorial"  strata  or  bitumen,  as  yet  recorded ; 
while  we  have  the  celebrated  "infusorial"  strata  of  Virginia,  which,  by  a  little  stretch 
of  the  imagination,  may  be  supposed  to  be  related  in  some  way  to  the  petroleum  of 
West  Virginia  and  Pennsylvania.  In  Algeria  we  have  "infusorial"  strata  and  bitumen ; 
but  I  never  heard  of  guano  having  been  found  near  by.  From  all  of  these  facts,  and 
others  that  I  have  collected  of  no  less  importance,  derived  from  chemical  and  micro 
scopical  characters,  I  have  come  to  the  conclusion  that  guano  is  not  the  excreta  of 
birds,  deposited  upon  the  islands  and  main  land  after  their  upheaval,  but  that  it  is  the 
result  of  the  accumulation  of  the  bodies  of  animals  and  plants,  for  the  most  part 
minute,  and  belonging  to  the  group  which  Haeckel  has  included  in  a  new  kingdom, 
separate  from  the  animal  as  well  as  the  vegetable,  under  the  name  of  Protista,  and 
subsequently  upheaved  from  the  bottom  of  the  ocean.  Subsequent  chemical  changes 
have  transformed  it  into  guano,  or,  heat  and  pressure  have  so  acted  upon  it  that  the 
organic  matter  has  been  transformed  into  bitumen,  while  the  mineral  constituents  are 
preserved  in  the  beautiful  atomies  that  make  up  the  mass  of  the  extensive  "infusorial" 
strata  found  in  various  parts  of  the  world. 

The  Chincha  islands  have  been  visited  by  a  competent  geologist,  Mr.  Kinahan,  of 
Dublin,  and  he  has  pointed  out  that  they  have  been  upheaved  by  volcanic  action  within 
a  recent  period,  geologically  considered.  I  have  found  a  remarkable  confirmation  of 
my  theory  in  a  paper,  read  before  the  American  Institute,  New  York,  some  years  since, 
by  Mr.  Alanson  Nash,  detailing  the  observations  of  a  Mr.  F.  Nash  made  during  a  resi- 


NATURAL    HISTORY    OF   THE    DIATOMACE^E. 

dence  on  the  Chincha  islands,  while  engaged  in  the  guano  trade,  for  nearly  six  months. 
Therein  we  find  it  stated  that  Mr.  Nash  was  of  opinion  that  guano  was  formed  in  the 
way  I  have  described  ;  that  the  anchors  of  vessels  in  that  locality  bring  up  guano  from 
the  bottom  of  the  ocean  ;  that  "  the  guano  is  (much  of  it)  not  composed  of  bird  dung, 
but  is  composed  of  the  mud  of  the  ocean;"  that  "the  composition  taken  from  the 
islands,  called  guano,  is  stratified,  and  lies  in  the  same  form  it  did  before  it  was  lifted 
up  from  the  ocean ; "  that  ' '  the  bottom  of  the  ocean,  on  the  west  coast  of  Peru,  con 
tains  vast  deposits  of  guano.  An  island,  during  an  earthquake,  rose  up  in  the  bay  of 
Callao,  some  years  since,  from  the  sea,  containing  guano  four  feet  deep,  the  formation 
the  same  as  the  Chincha  islands."  In  conclusion,  he  says,  "the  day  will  come  when 
the  guano  at  these  islands  will  be  dredged  up  with  boats  like  mud  from  our  rivers  and 
harbors."  And  in  this  expectation  I  fully  coincide  with  Mr.  Nash. 

Sea  mud  has  been  found  to  yield  an  excellent  article  of  fertilizer,  and 
is  collected  for  that  purpose  at  different  points  along  our  coast.  That 
from  the  harbor  of  Charleston,  S.  C.,  yielded  to  the  late  Prof.  Bailey  a 
rich  harvest  of  diatomaceous  forms;  and  I  have  examined  the  same 
material,  as  well  as  that  used  in  Salem,  Mass.,  for  the  same  purpose, 
and  known  as  "mussel  bed,"  and  have  found  them  both  to  be  full  of 
microscopic  forms. 

Some  years  since  Prof.  Gregory  described  a  remarkable  deposit  of  sand 
from  Glenshira,  which  he  considered  to  be  fossil,  and  called  it  post-ter 
tiary.  It  was  full  of  the  remains  of  diatomacese,  both  marine  and  fresh 
water,  and  had  been  formed  evidently  by  the  ingress  of  the  salt  water  of 
the  bay  into  a  fresh  water  pond.  Occasionally  we  find  the  bottom  of 
fresh  water  marshes  upheaved  and  everted  by  superincumbent  pressure 
from  railroads  or  other  passage  ways  being  built  across  them.  Under 
these  circumstances  there  are  often  developed  deposits  of  the  remains  of 
diatomacese.  I  have  one  such  specimen  from  Detroit,  Mich.  I  have  also 
seen  two  examples  of  the  everting,  in  this  way,  of  the  ancient  bed  of  salt 
marshes,  and  in  both  cases  the  remains  of  diatomaceas  are  plentiful. 

The  importance  of  a  knowledge  of  the  diatomaceae  to  the  geologist 
has  been  lost  sight  of  up  to  the  present  time ;  but  now  that  the  state  of 
New  Hampshire  has  taken  the  lead  in  this  matter,  it  is  to  be  hoped  that 
they  will  be  studied,  as  they  occur  in  the  rocks  of  other  localities.

DIRECTIONS    FOR    COLLECTING,    PRESERVING,    AND    TRANSPORTING 
SPECIMENS  OF  DIATOMACE.«. 

The  diatomacese  constitute  a  group  of  organisms  of  so  much  interest 
to  the  student  of  natural  history,  that  it  is  desirable  that  specimens 
should  be  collected  in  various  parts  of  the  world.  That  such  collections 
may  be  of  value,  it  is  necessary  that  they  should  be  made  in  a  proper 
manner ;  and  for  the  purpose  of  facilitating  the  making  of  such  collections 
these  directions  have  been  drawn  up.  The  directions  given  should  be 
closely  followed,  as  the  methods  described  have  been  found,  after  consid 
erable  trial,  to  be  those  yielding  the  most  satisfactory  results.  As  the 
fossil  deposits  containing  the  remains  of  diatomacese  are  most  readily 
recognized,  gathered,  and  forwarded,  they  will  be  first  described. 

Fossil  Deposits.  Included  under  this  head  must  be  considered  the 
enormous  sub-plutonic  strata  found  on  the  Pacific  coast  of  North  Amer 
ica,  so  that  the  fossil  deposits  of  diatomacese  may  be  said  to  contain  both 
fresh-water  and  marine  species,  though  never  in  a  mixed  state.  In  some 
cases  the  particular  species  present  indicate  the  character  of  the  piece  of 
water  in  which  the  deposit  has  accumulated,  different  forms,  or  groups 
of  forms,  appearing  in  bays,  ponds,  lakes,  marshes,  springs,  and  rivers,  and 
at  various  points  of  elevation  above  the  surface  of  the  sea. 

The  principal  fossil  deposits  of  diatomaceae  hitherto  discovered  contain 
marine  species,  and  extend  over  considerable  tracts  of  the  earth's  surface. 
The  most  important  stratum  of  this  character  is  considered  to  belong 
to  the  miocene  tertiary,  and  is  found  on  the  Atlantic  side  of  North 
America,  not  far  from,  and,  in  fact,  in  some  places,  reaching  down  to 
the  coast.  It  is  known  to  extend  from  the  Patuxent  river,  in  Maryland, 
as  far  south  as  the  city  of  Petersburg,  in  Virginia.  How  much  beyond 
these  two  points  it  extends  has  not  been  ascertained,  but  is  found  under 
lying  the  cities  of  Petersburg,  Richmond,  and  Fredericksburg,  in  Virginia, 
and  at  many  other  points  in  that  state  as  well  as  in  Maryland.  It  is 
desirable  to  obtain  specimens  from  different  points  in  this  bed,  as  it  varies 
in  character,  and  contained  organisms  with  every  few  miles  of  surface, 
and  at  different  points  in  its  depth. 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  479 

Strata  of  this  kind  vary  greatly  in  appearance,  as  well  as  in  micro 
scopic  character.  Therefore  the  following  general  directions  will  suffice 
to  guide  collectors  in  searching  for  and  detecting  them. 

Gather  all  earths  of  light  color,  varying  from  a  pure  white,  through 
different  shades  of  grey,  cream,  and  fawn,  to  an  iron-rust  tint.  The 
texture  is  often  friable,  and  then  looks  somewhat  like  clay,  especially 
when  it  is  wet;  at  other  times  it  is  of  a  hard  and  stony  character, 
though  always  more  or  less  porous,  and,  when  soft,  of  little  weight. 
A  moderate  magnifying  power  shows  it  to  be  made  up  of  the  shells 
of  diatomaceae.  Collect  enough  to  make  up  three  or  four  pounds' 
weight,  or,  say,  a  block  six  or  eight  inches  square,  and,  if  possible,  from 
the  surface  and  at  various  depths,  for  the  reasons  already  stated.  Some 
of  the  localities  of  this  material  may  be  mentioned.  In  Virginia  it  has 
been  procured  in  and  near  Petersburg  and  Richmond,  at  Shockhoe  hill 
and  Church  hill,  and  at  Hollis  cliff;  and  in  Maryland,  at  Lower  Marlboro', 
Nottingham,  Piscataway,  and  Rappahannock  cliff. 

Besides  the  above  mentioned,  an  extremely  interesting  stratum  of  a 
similar  character,  but  in  general  of  harder  texture,  has  been  found  on 
the  Pacific  coast  of  North  America,  and  extending  at  least  from  San 
Francisco  to  the  lower  border  of  California,  if  not  farther,  in  both  direc 
tions.  This  substance  makes  up  the  major  part  of  the  rocks  of  the  coast 
range  of  mountains,  and  has  been  named  the  bituminous  shales.  It  was 
first  detected  at  Monterey,  and  is  known  to  microscopists  in  England  as 
"  Monterey  stone,"  but  it  has  since  been  traced  and  brought  from  various 
points.  Santa  Cruz,  San  Pedro,  and  San  Diego  have  yielded  excellent 
specimens  containing  many  beautiful  forms  of  diatomaceae.  It  is  usually 
light  fawn-colored,  and  distinctly  stratified.  Large  fossil  shells  are  found 
in  it ;  and  associated  with  and  in,  if  not  derived  from  it,  is  the  bitumen  of 
California.  At  Baldjik,  near  Varna  in  Bulgaria,  on  the  Black  sea,  is  a 
stratum  of  stony  character,  having  shells  and  bones  dispersed  through  it. 
The  diatomaceae  found  in  it  are  apparently  of  brackish-water  origin,  and 
this  is  the  only  stratum  of  this  kind  that  is  known.  But  very  little  of 
this  material  has  found  its  way  into  the  hands  of  naturalists.  On  the 
island  of  Jutland,  in  Denmark,  is  found  a  polishing  slate  which  is  rich  in 
diatomaceous  forms  not  found  anywhere  else.  This,  also,  is  rare  among 
naturalists,  and  a  good  supply  of  it  is  very  desirable.  At  Oran  in 


480  PHYSICAL    GEOGRAPHY. 

Algeria,  Africa,  and  at  JEg'ma.  and  Caltanisetta  in  Greece,  are  deposits 
containing  the  remains  of  diatomaceae  intermixed  with  polycystina  and 
foraminifera,  and  referred  to  the  Cretaceous.  In  the  island  of  Barba- 
does  are  so-called  marls  made  up  of  diatomaceae  and  polycystina,  the 
latter  in  great  numbers  and  very  beautiful.  In  the  island  of  Trinidad,  at 
South  Naparima,  a  similar  stratum  has  lately  been  discovered  which  "is 
considered  as  connected  with  the  new  red  sandstone;  adjoining  to  which 
is  the  sandstone,  probably  of  the  same  description,  in  which  the  Pitch 
lake  is  situated."  At  Moron,  in  Spain,  has  been  found  a  similar  deposit 
of  marine  diatomaceae;  and  still  another  was  discovered  by  Dr.  C.  F. 
Winslow  at  a  point  about  seventy  miles  south  of  the  town  of  Payta,  in 
Peru,  and  about  fifteen  miles  from  the  Pacific  ocean.  Here  is  a  plain 
separated  from  the  sea  by  a  range  of  hills  several  hundred  feet  high. 
Within  the  plain  is  a  depression  with  nearly  perpendicular  walls  two 
hundred  feet  high,  the  bottom  of  which  depression  is  at  about  the  level 
of  the  sea — perhaps  a  little  lower.  The  surface  of  the  soil  thereabouts 
is  covered  with  salt.  For  fifteen  feet  down  there  is  a  deposit  containing 
recent  shells,  the  bones  of  cetacea,  and  pebbles;  then,  for  one  or  two 
feet,  is  a  yellow  loam,  and,  at  the  bottom,  is  the  stratum,  containing  the 
diatomaceae,  which  is  from  two  to  four  feet  thick.  The  amount  Dr. 
Winslow  brought  away  was  very  small,  and  this  is  all  that  has  got  into 
the  hands  of  microscopists.  Prof.  Pumpelley  brought  from  near  Netanai, 
in  Japan,  specimens  of  a  like  deposit.  Very  small  fragments  of  the 
strata  from  Jutland,  Trinidad,  Moron,  Payta,  and  Japan  have  been  se 
cured  ;  so  it  is  extremely  desirable  that  those  localities  should  be  again 
visited,  the  geological  relations  of  the  strata  ascertained,  and  a  plentiful 
supply  of  the  material  gathered.  The  sub-plutonic  deposits  seem  to  be 
confined  to  the  Pacific  coast  of  the  North  American  continent,  and  near 
by.  At  Five-mile  canon,  near  Virginia  city,  Nevada,  is  an  enormously 
thick  stratum  of  this  character,  which  is  ground  and  sold  considerably 
under  the  name  of  "electro  silicon,"  as  a  polishing  powder.  At  Klamath 
lake,  on  the  banks  of  the  Columbia  and  Pitt  rivers,  and  elsewhere,  at 
many  points,  these  deposits  have  been  found. 

The  rules  already  given  hold  good  with  regard  to  gathering  specimens 
of  all  of  these  deposits.  Everything  that  can  be  ascertained  with  regard 
to  their  position  and  relations  should  be  noted.  Also,  any  fossils  con- 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  481 

tained  in  them,  or  in  the  strata  above  or  below  them,  should  be  gathered, 
and  their  position  noted  on  the  labels  accompanying  them.  All  specimens 
should  be  kept  carefully  separate  (not  even  permitting  them  to  come  in 
contact)  by  wrapping  each  one  in  paper,  placing  within  a  label  having 
written  upon  it  in  ink  the  exact  locality,  date  of  collection,  and  name  of 
collector.  It  is  also  desirable  that  note  should  be  made  of  the  depth 
from  the  surface  at  which  the  specimen  was  taken,  together  with  any 
other  information  that  may  be  deemed  of  interest,  as  supposed  extent  of 
stratum,  slope-upwards  towards  north,  south,  east,  or  west,  and  thickness. 

Lacustrine  Sedimentary  Deposits.  These  were  called  by  me  at  one 
time  sub-peat  deposits,  from  the  fact  that  all  I  had  seen  up  to  that  time 
had  been  discovered  beneath  peat;  but  as  the  number  of  these  strata 
which  have  come  into  my  hands  has  increased,  I  have  seen  many  which 
do  not  occur  under  such  circumstances;  hence  the  above  name  has 
been  applied  to  them  as  being  more  appropriate,  and  indicating  their 
most  common  mode  of  occurrence.  In  England  they  are  called  fossil; 
but  in  the  true  acceptation  of  that  term  the  forms  contained  in  them 
are  not  fossils,  but  are  identical  with  living  species. 

They  are  generally  of  a  pulverulent  character,  and,  when  dry,  are  of 
little  weight,  so  much  so  as  to  attract  attention.  When  free  from  organic 
matter,  as  occasionally  occurs,  they  are  quite  white,  looking  almost  like 
powdered  starch ;  but  most  commonly  they  are  grey,  which  looks  dark 
while  the  material  is  wet,  but  when  dried  the  color  is  light.  A  mass  of 
about  six  or  eight  pounds'  weight  should  be  secured,  and  the  same  pre 
cautions  as  to  keeping  separate  and  labelling  specimens  adhered  to,  as 
have  been  already  mentioned.  As  these  beds  are  seldom  of  any  great 
extent  (they  often  soon  become  obliterated  or  covered  up),  it  will  be  well 
to  secure  a  good  supply  of  the  material  while  it  is  accessible.  If  any 
shell,  wood,  or  other  organic  remains  should  be  found  dispersed  through 
the  deposit,  or  overlying  or  beneath  it,  they  should  also  be  secured,  and 
their  position  recorded  on  the  label.  Likewise,  a  sample  of  any  superin 
cumbent  peat  should  be  kept  for  future  examination.  In  Sweden  and 
Norway,  and  in  Lapland,  these  deposits  have  been  used  to  eke  out  a 
scanty  supply  of  flour  during  bad  seasons ;  but  they  can  hardly  be  said 
to  be  food,  for  they  are  not  nutritious,  but  most  likely  only  act  by  their 

mass  distending  the  stomach,  and  thus  allaying  for  a  time  the  pangs  of

hunger.  They  have  likewise  very  frequently  been  employed,  under  the 
name  of  "tripoli,"  as  a  polishing  material,  and  are  excellent  for  that  pur 
pose.  In  some  parts  of  this  country  they  go  by  the  name  of  "marl,"  but 
they  are  not  examples  of  that  substance,  which  is  calcareous,  being  made 
up  of  the  remains  of  the  shells  of  mollusca.  Specimens  from  every 
locality  are  desirable. 

Muds  and  Deposits  from  tJic  bottoms  of  harbors,  bays,  lakes,  ponds, 
estnarics,  and  rivers.  As  a  general  thing  these  are  not  of  very  great 
value  to  the  microscopist  for  the  remains  they  contain,  and  it  is  only  de 
sirable  to  collect  them  in  localities  or  under  circumstances  where  other 
gathering  cannot  be  made,  or  when  they  are  known  to  contain  any  organ 
isms  of  great  beauty  or  rarity.  The  blacker  and  softer  the  mud  the 
better,  for,  if  it  contains  much  sand  or  gravel,  the  minute  organisms  will 
be  present  in  just  so  much  less  proportion.  As  much  as  can  be  conven 
iently  transported,  say  about  a  handful,  should  be  collected,  and,  if  possi 
ble,  not  dried,  but  placed  in  a  bottle  and  tightly  corked ;  or,  it  may  have  a 
little  glycerine  added  to  it,  which  will  prevent  its  drying, — for  it  has  been 
found  that  muds,  and  especially  those  from  salt-water,  when  once  dried, 
are  only  with  difficulty  broken  down  again  so  as  to  be  cleaned.  The 
mud  and  slime  attached  to  anchors,  buoys,  and  submerged  woodwork, 
together  with  the  scrapings  from  the  bottoms  of  vessels  containing  shells, 
plants,  zoophytes,  etc.,  may  be  simply  dried  in  the  sun,  and  then  have  a 
label  attached.  The  mud  from  beneath  fresh  water  is  of  little  value,  as 
it  rarely  contains  any  organisms  of  beauty;  but  the  marine  forms  found 
in  mud  are  occasionally  fine,  beautiful,  and  rare. 

Guano.  This  substance  often  contains  species  of  diatomacerc  not 
otherwise  obtainable.  It  is  the  ammoniacal  guanos  alone,  however,  which 
I  have  found  to  yield  any  great  number  of  diatomaceous  forms ;  but 
there  are  certain  guanos,  of  which  one  known  as  "Bolivian  guano"  is  an 
example,  partly  ammoniacal  and  partly  phosphatic,  which  contain  some 
forms  not  otherwise  obtainable.  Quantities  of  a  pound  or  two  in  weight 
should  be  secured,  and  the  exact  locality  of  the  island  or  other  place  from 
which  it  was  obtained,  together  with  the  latitude  and  longitude,  and  other 
information  that  may  be  collected  and  deemed  of  interest,  should  be 
marked  in  ink  upon  the  label. 

Shell  Cleanings.     The  sand,  mud,  algce,  zoophytes,  and  similar  matters 


NATURAL    HISTORY    OF    THE    DIATOMAEC/E.  483 

adherent  to  marine  shells,  which  are  commonly  removed  by  students  of 
conchology,  have  often  been  found  to  yield  rich  harvests  of  rare  forms  of 
diatomaceae.  Such  material  can  be  washed,  or,  still  better,  scraped  off  of 
the  living  or  dead  shells  (the  dirtier  such  shells  seem  the  better,  of  course), 
placed  in  paper  and  plainly  labelled  with  the  exact  locality,  and,  if  possi 
ble,  name  of  the  shell  and  depth  of  water  from  which  it  was  taken.  Con- 
chologists  will  do  well  to  save  all  their  shell-cleanings  for  this  purpose. 

Marine  Ini'crtcbrata.  Specimens  of  the  entire  animal,  or  the  contents 
of  the  stomachs  of  echinoidea  (sea  urchins)  and  holothuroidea  (sea  cu 
cumbers),  should  be  secured,  as  it  has  been  found  that  many,  if  not  most 
of  them,  are  vegetable  feeders,  and  thus  take  into  their  stomachs  algae 
which  have  diatomaceae  growing  upon  them.  The  entire  animal  should 
be  preserved  in  spirits  (if  alcohol  is  not  procurable,  brandy  or  whiskey 
will  answer),  but  if  that  be  not  convenient,  they,  as  well  as  the  contents 
of  the  stomachs,  may  be  dried  without  washing  in  any  way.  It  has  been 
found  that  holothurians,  when  they  are  immersed  in  spirit,  often  turn 
their  stomachs  inside  out,  and  thus  the  contents,  which  are  the  part  most 
valuable  for  the  microscopic  organisms,  will  be  found  at  the  bottom  of 
the  containing  vessel.  When  the  whole  animal  is  preserved  in  spirit,  the 
label  may  be  written  in  ink  on  stiff  paper  or  parchment,  and,  when  quite 
dry,  tied  to  the  specimen  and  immersed  with  it  in  the  spirit.  In  this  way 
several  specimens  can  be  preserved  in  the  same  vessel,  and  space  econo 
mized.  This  method  will  be  found  to  be  the  best,  as  labels  pasted  or 
gummed  on,  or  otherwise  attached  to  the  vessel,  are  liable  to  be  obliter 
ated  from  leakage  of  the  contained  fluid,  or  removed  during  transporta 
tion.  The  stomachs  of  mollusca  (shell  fish)  and  crustaceans  (lobsters, 
crabs)  also  occasionally  yield  specimens  of  diatomaceae,  and  it  will  be 
well  to  secure  specimens  of  those  creatures  in  the  manner  described. 
'The  stomachs  of  fish  occasionally  contain  diatomaceae,  and  may  be

Soundings.  The  material  brought  up  from  the  ocean  bed  by  the 
sounding-line,  or  the  larger  masses  procured  by  means  of  the  dredge, 
have  been  found  to  yield  good  returns  of  microscopic  treasures  when 
examined.  The  calcareous  shells  of  foraminifera,  as  well  as  siliceous 
polycystina  and  diatomaceae,  are  found  in  them.  When  kept  for  this 
purpose,  note  should  be  made  of  the  latitude  and  longitude,  depth  of

water,  along  with  the  name  of  the  vessel  and  collector,  and  the  date  of 
collection. 

TJic  dust  wJiich  collects  at  sea  upon  tJie  sails  or  decks  of  vessels.  This 
kind  of  material,  although  not  common,  has  been  found  to  be  of  interest 
when  examined  microscopically.  It  can  generally  be  scraped  up  with  a 
piece  of  paper.  When  the  quantity  is  so  small  that  it  cannot  be  col 
lected  in  this  way,  a  piece  of  damp  paper  may  be  laid  on  it  once  or 
twice,  in  several  places,  and  then  folded  up  before  it  becomes  dry.  Lati 
tude  and  longitude,  direction  of  wind  at  the  time  of  the  falling  of  the 
dust,  name  of  vessel,  date,  and  collector's  name,  should  be  noted  on  the 
label. 

Recent  gatherings  of  Diatomacc<z.  These  are  the  most  valuable,  im 
portant,  and  rich  of  the  gatherings  containing  diatomaceae  on  which  the 
student  depends  for  material  for  investigation,  and  they  are  so  various  in 
character  that  it  becomes  difficult  to  give  general  directions  that  will 
serve  to  indicate  the  modes  of  procedure  to  be  followed  in  securing 
them.  To  collect  diatomaceae  at  all  thoroughly,  a  considerable  amount 
of  knowledge  of  their  habits  is  necessary.  In  general,  it  may  be  said 
that  gatherings  should  be  made  of  marine  plants,  or  algae  as  they  are 
called,  which  grow  entirely  submerged  beneath  the  water,  attached  to 
rocks,  piers,  iron-,  or  wood-work.  The  dirtier  such  plants  appear  to  the 
naked  eye,  the  richer  will  be  the  harvest  of  minute  organisms  secured, 
as  the  brown  coating,  seen  upon  aquatic  plants  and  similar  submerged 
objects,  obscuring  them,  is  but  a  mass  of  living  diatomaceae.  The  larger 
and  coarser  algae, — more  especially  those  having  a  slimy  feel, — do  not 
usually  yield  many  diatomaceae ;  but  the  finer  brown,  red,  or  green  fila 
mentous  kinds  are  commonly  covered  with  them.  Detached  fragments 
thrown  up  upon  the  beach  ought  not  to  be  kept  if  living  ones  can  be 
found,  for  they  usually  have  had  the  diatoms  rubbed  off  from  them,  and 
are,  besides,  contaminated  with  sand.  The  living  algae  taken  from  their 
attachment  should  be  dried  without  washing  or  much  compressing,  and 
may  then  be  placed  in  layers,  each  specimen  being  plainly  labelled  with 
the  exact  locality,  date  of  collection,  and  collector's  name.  Fragments  of 
algae,  which  may  break  off  from  cabinet  specimens,  and  would  be  rejected 
by  students  of  the  algae,  may  yet  be  of  value  to  the  diatomist.  Some  of 
the  finest  collections  I  have  ever  seen  were  derived  from  this  source. 


NATURAL   HISTORY   OF   THE   DIATOMACE^.  48$ 

When  known,  the  name  of  the  alga  should  be  stated.  If  possible,  it 
is  extremely  desirable  to  secure  specimens  of  diatom-encrusted  algae  in 
spirits.  In  this  way  the  diatoms  will  be  preserved  in  almost  their  natu 
ral  condition ;  and  those  species,  which  are  filamentous  or  grow  in  chains, 
will  be  available  in  that  condition  for  study. 

Fresh-water  plants  clouded  with  diatomacese  may  be  collected  and 
preserved  in  the  same  manner  as  marine  algae.  As  has  been  remarked, 
the  finer  filamentous  species  of  water  plants  yield  the  best  results ;  the 
marine  fucoids,  as  the  "bladder  wrack,"  and  similar  species,  secrete  a 
mucus  which  seems  to  be  repugnant  to  the  growth  of  most  diatoms ;  yet 
upon  the  stalks  of  Laminaria,  and  some  other  large  olive-colored  algae,  are 
found  the  finer  red-tinted  species,  which  are  themselves  beautiful  objects 
of  study,  and  are,  in  turn,  the  homes  of  hosts  of  minute  forms  of  life. 
Water  plants,  marine  or  fresh-water,  should  not  be  cleaned  in  any  way, 
but  merely  raised  from  the  water,  and,  after  draining  for  a  short  time,  be 
either  laid  upon  a  piece  of  clean  paper  to  dry,  or  hung  up  where  the  air 
and  sun  can  rapidly  evaporate  the  moisture.  Marine  plants  will  usually 
not  dry  thoroughly,  as  the  salts  present  in  the  water  absorb  moisture 
from  the  air ;  hence  they  are  liable  to  mould  unless  they  are  packed  in 
paper.  The  moss-like  carpeting  seen  upon  submerged  rocks  is  often 
made  up  of  beautiful  specimens  of  the  filamentous  species  of  diatoms 
alone,  and  it  will  be  well  to  scrape  the  surface  of  the  stone,  and,  placing 
the  mass  in  a  bottle,  cover  it  with  alcohol,  which  will  become  colored 
from  dissolving  the  coloring  matter  of  the  diatoms,  and  preserve  them 
in  the  very  best  manner  for  future  study.  Fresh-water  forms  are  very 
often  found  hanging  in  green-colored  festoons  from  the  exit  pipe  of 
drains,  sluices,  or  fountains,  and  may  be  preserved  in  the  same  way. 

The  green,  brown,  or  fawn-colored  scum  which  floats  upon  the  surface 
of  the  water  of  road-side  pools,  ponds,  bogs,  marshes,  or  rivers,  consists 
usually  of  little  else  but  diatoms,  and  may  be  taken  up  by  means  of  a 
spoon  or  bottle,  and  then  preserved  in  alcohol  or  dried  upon  paper.  The 
surface  of  the  sea  may  be  skimmed  by  means  of  a  net  of  fine  muslin, 
having  an  opening  left  in  the  bottom,  in  which  a  four-  or  six-ounce  wide- 
mouth  phial  is  tied,  and  towed  at  the  stern  of  a  vessel.  If  the  sea-water 
be  strained  through  such  a  net,  either  by  towing  behind  a  boat  or  even 
poured  from  a  pail,  the  solid  matter  contained  in  it  will  be  washed  down 


486  PHYSICAL    GEOGRAPHY. 

and  gradually  collect  in  the  phial,  which  can  then  be  removed  and  tightly 
corked,  and  another  substituted.  Some  very  beautiful  forms  have  been 
procured  in  this  way.  The  stain  occasionally  seen  on  the  surface  of  the 
sea  in  some  latitudes,  as  well  as  the  minute  organisms  causing  the  lumi 
nosity  of  the  ocean,  yield  rich  crops  of  diatoms,  and  should  be  secured. 
Such  gatherings  may  be  put  up  as  obtained,  or  have  alcohol  added  to 
them  for  better  preservation.  The  collection  of  aquatic  plants  from  the 
mouths  of  rivers  is  extremely  desirable, — such  as  have  been  made  in  the 
delta  of  the  Ganges  yielding  interesting  results.  The  refuse  of  dredging 
for  shells  often  yields  mud,  old  shells,  or  algae ;  and  collectors  will  do  well 
to  secure  such.  Experience,  however,  will  teach  the  best  places  to  look 
for  recent  diatoms ;  but  the  above  general  directions  will  prove  of  service 
to  those  who  are  new  to  the  pursuit,  or  who  collect  for  others. 

It  should  always  be  remembered  that  a  knowledge  of  the  exact  locality 
is  of  the  greatest  importance, — so  that  upon  the  label  should  be  written 
in  ink  the  locality,  date  of  collection,  and  name  of  collector.  Other 
facts  deemed  of  interest  may  also  be  added. 

PART    EIGHTH. 

How  TO  PREPARE   SPECIMENS  OF  DIATOMACE^E  FOR  EXAMINATION  AND 
STUDY  BY  MEANS  OF  THE  MICROSCOPE. 

Having  accumulated  a  number  of  gatherings  of  rough  material,  which, 
a  cursory  examination  has  shown,  contain  specimens  of  diatomaceas,  and 
which,  it  is  judged,  it  will  answer  to  clean  and  otherwise  arrange  and  put 
up,  or,  as  it  is  technically  termed,  "mount,"  for  future  study,  the  intend 
ing  diatomist  requires  to  be  informed  how  he  may  best  set  about  pre 
paring  his  specimens  in  the  most  advantageous  manner.  The  author  of 
the  present  sketch  has  published,  in  the  seventh  volume  of  the  Proceed 
ings  of  tJie  Boston  (Mass.)  Society  of  Natural  History,  certain  directions 
for  collecting,  preparing,  and  mounting  diatomaceee  for  the  microscope; 
and,  as  that  paper  contains  a  large  part  of  the  information  he  desires  to 
impart  at  the  present  time,  he  will  draw  upon  it  pretty  freely,  supple 
menting  it  to  such  a  degree  as  later  investigations  warrant,  or  as  may 
seem  desirable. 

Although  most  of  the  published  treatises  on  the  use  of  the  microscope 
in  general  profess  to  give  directions  for  mounting  objects  in  such  a 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  487 

manner  as  to  preserve  them  for  almost  any  length  of  time,  and  at  the 
same  time  exhibit  their  characters  to  the  best  advantage,  and  although 
we  have  in  the  English  language  at  least  three  books  treating  specially 
of  this  subject  of  the  preparation  of  microscopic  objects,  yet  hardly  any 
one  of  these  volumes  gives  any  concise,  practical,  and,  at  the  same  time, 
reliable  descriptions  of  the  best  methods  of  collecting,  preparing,  and 
mounting  specimens  of  diatomacere.  In  books,  generally,  when  the 
preparation  of  these  organisms  is  treated  of,  it  is  usually  the  fossil 
deposits  which  are  considered,  and  even  such  directions  as  relate  to 
these  are  for  the  most  part  meagre  and  unsatisfactory;  and,  when  the 
specific  and  special  directions  are,  as  is  often  the  case,  copied  from  one 
book  into  the  other  without  having  been  tested  by  the  copyist,  any 
faults  they  may  have  possessed,  as  originally  written,  are  merely  repeated 
and  not  eliminated.  To  prepare  and  mount  specimens  of  diatomacex, 
for  the  purpose  of  sale  alone,  is  one  thing,  and  to  prepare  and  mount 
them,  so  as  to  preserve  and  exhibit  their  natural  characters  and  fit  them 
as  objects  of  scientific  study,  is  another  and  very  different  thing.  The 
latter  can  only  be  attained  after  considerable  practice,  and  to  do  it  prop 
erly  a  considerable  amount  of  knowledge  of  their  natural  history  is 
plainly  necessary. 

The  diatomaceas  should  always  be  prepared  and  put  up  for  a  special 
purpose, — that  of  exhibiting  characters  peculiar  to  genera  and  species ; 
and  to  do  this  those  characters  must  of  course  be  known.  Muds, 
guanos,  dredgings,  and  gatherings  of  that  description  can  seldom  be 
used  for  the  purpose  of  exhibiting  such  characters,  and  when  they  can, 
in  exceptional  cases,  be  so  employed,  it  is  when  the  forms  they  contain 
are  selected  out  in  the  manner  to  be  described  hereafter.  Gatherings, 
likewise,  which  contain  many  species  in  a  mixed  condition,  should,  as  a 
general  thing,  be  rejected  unless  there  be  present  something  of  special 
importance,  such  as  rare  species,  or  some  large  and  fine  or  distorted 
forms  of  common  species.  But  even  in  such  cases  it  will  be  found  best 
not  to  mount  the  gatherings  as  collected,  but  to  select  out  the  forms 
desired  and  place  them  upon  slides  by  themselves,  and  in  such  media  as 
will  exhibit  their  peculiarities  to  the  best  advantage.  Of  course  it  may 
be  desirable  to  study  the  geographical  distribution  of  the  diatomacere; 
and  then  mixed  gatherings  become  of  value  as  exhibiting  the  number  of 


488  PHYSICAL    GEOGRAPHY. 

forms  occurring  at  a  particular  station.  Then,  again,  the  fossil  as  well 
as  the  semi-fossil  deposits  and  guanos  may  be  cleaned  and  mounted  as 
obtained ;  but  even  then  it  may  become  desirable,  if  space  can  be  spared 
in  the  cabinet,  to  have  the  various  species  found  in  each  gathering  sepa 
rately  mounted,  so  that  they  may  be  at  any  time  studied  in  comparison 
with  similar  forms  from  other  localities. 

General  directions  for  collecting  diatomaceoe  have  been  already  given 
in  Part  Seventh ;  but  it  will  be  desirable  to  again  allude  to  a  few  points 
in  connection  with  this  portion  of  our  subject.  Some  years  since,  an 
article  entitled  "  Hunting  for  Diatoms "  was  published  in  a  London 
journal  called  TJie  Intellectual  Observer.  The  author's  name  was  not 
given,  but  internal  evidence  would  seem  to  indicate  that  it  was  penned 
by  a  deceased  botanist  of  note,  who  was  a  decided  authority  on  this 
branch  of  biology.  This  paper  contains  some  valuable  hints  respecting 
the  places  in  which  to  look  for  diatoms,  and  some  of  the  suggestions 
contained  therein  I  have  ventured  to  transfer  to  these  pages,  as  they  will 
be  found  of  value  to  the  intending  diatomist.  Thus,  the  exquisite  Arach- 
noidiscus,  Triccratium  Wilkcsii,  and  Aulacodiscus  Orcgonensis,  may  be 
looked  for  on  logs  of  wood  which  have  been  floating  in  the  sea,  and 
imported  from  New  Zealand,  or  Vancouver's  island.  So,  on  logs  from 
Mexico  and  Honduras  may  be  found  the  curious  Terpsincs  musica.  The 
nets  of  fishermen,  especially  from  deep  water,  may  yield  algae  bearing 
such  forms  as  RJiabdoncma  arcuatum  or  Adriatium,  Grammatophora 
serpentina  and  marina,  various  Syncdras,  and  other  fine  forms.  On 
oyster  shells  may  be  found  algae  bearing  upon  their  fronds  Biddulphia 
rcgina,  Baileyii  or  aurita.  RJiizosolcnia  styliformis  is  said  to  be  almost 
sure  to  be  there  likewise.  After  a  ship  is  unloaded,  and  as  it  floats 
higher  in  the  water,  its  sides  may  be  searched  for  treasures  of  the  diatom 
world,  and  Achnanthcs  longipes  and  brcvipes  found,  or  even  Diatoma 
Jiyalinum  and  Hyalosira  dclicatula.  The  sea-grass,  or  Zostcra  marina, 
growing  along  our  coast,  often  bears  upon  its  waving  ribbons  fine  forms 
of  diatoms,  and  that  used  for  stuffing  chairs,  and  lounges  or  mattresses, 
and  imported  from  abroad,  will  yield  foreign  species  to  the  collector. 
There  is  a  plant  known  in  England  as  "  Dutch  rushes,"  which  is  imported 
into  that  country  from  Holland,  and  which  is  used  for  chair  bottoms. 
These  plants  grow  in  the  brackish  water  of  the  marshes,  and  hence  upon 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  489 

them  are  to  be  found  the  delicate  Coscinodiscus  snbtilis,  Enpodiscus 
argns,  and  Triccmtinm  favns.  Both  of  these  two  last  named  forms  occur 
commonly  on  our  Atlantic  coast,  and  muds  from  Charleston,  S.  C,  and 
Wilmington,  Ga.,  have  provided  me  with  them  in  plenty.  Cargoes  of 
bones,  which  present  green  incrustations  from  having  lain  in  the  water 
for  some  time,  are  said  to  yield  diatoms,  some  of  which  may  be  rare,  as 
coming  from  foreign  ports.  The  state  of  New  Hampshire  has  not  yet 
been  sufficiently  gone  over  for  it  to  be  said  what  the  characteristic  forms 
of  diatomaceae  growing  within  its  boundaries  are,  but  yet  we  may  safely 
predict  that  the  lakes,  ponds,  streams,  and  sea-coast  of  that  state  will 
yield  to  the  searcher  ample  material  of  beautiful  forms. 

If  the  microscopist  wishes  to  mount  a  few  slides  of  recent  diatoms 
just  to  show  what  diatoms  are,  nothing  is  easier.  It  is  only  necessary  to 
boil  a  small  mass  of  them  in  strong  nitric  acid  in  a  test  tube  over  a  spirit 
lamp,  and,  when  the  acid  has  ceased  to  emit  red  or  yellowish  fumes, 
wash  them  thoroughly  with  clean  water,  allowing  them  to  settle  com 
pletely.  Then  a  little  of  the  clean  sediment,  consisting  almost  entirely 
of  the  shells  of  the  diatoms,  is  taken  up  by  means  of  a  "dip-tube,"  and 
placed  upon  the  central  portion  of  a  glass  slide.  Here  it  is  dried,  and  the 
slide  warmed  over  a  lamp ;  then  a  drop  of  Canada  balsam  is  permitted  to 
fall  upon  the  diatoms.  As  soon  as  all  bubbles  have  cleared  off  from  the 
balsam,  a  warm  cover  of  thin  glass  is  carefully  laid  upon  it  and  permitted 
to  settle  into  place.  When  cool,  it  is  ready  for  examination  by  means  of 
the  microscope,  any  balsam  which  has  exuded  around  the  cover  being 
washed  off  with  alcohol.  In  this  way  rough  and  tolerably  clean  speci 
mens  may  be  obtained ;  but  such  would  not,  or,  at  all  events,  should  not, 
satisfy  the  student  of  the  diatomaceae.  For  him  more  elaborate  methods 
are  necessary,  and  these  we  will  now  proceed  to  consider. 
-  Apparatus  and  clicmicals  necessary.  A  chemist's  retort-stand,  which 
is  a  heavy  iron  plate  with  an  upright  rod  projecting  from  one  side  of  it. 
Running  on  this  rod,  and  so  arranged  that  they  may  be  fixed  by  set- 
screws  at  any  height,  are  a  series  of  rings  of  various  diameters,  which 
are  to  be  used  to  hold  the  vessels  in  which  the  specimens  are  to  be 
manipulated  over  the  source  of  heat  used.  Mr.  C.  G.  Bush,  late  of  Bos 
ton,  Mass.,  who  has  had  considerable  experience  in  cleaning  diatomaceas, 

tells  me  that  he  uses  a  lamp  burning  petroleum  oil,  as  cheaper  than  a 
VOL.  i.     64 


49°  PHYSICAL    GEOGRAPHY. 

spirit-lamp,  and,  to  support  the  vessels  he  employs,  has  a  little  metal 
arrangement  on  the  top  of  the  chimney,  such  as  is  supplied  for  the  pur 
pose  of  holding  a  small  tea-kettle  and  the  like.  The  only  objection  to 
the  oil-lamp  is,  that,  unless  the  wick  be  well  turned  down,  we  arc  liable  to 
have  our  vessels  blackened.  However,  the  heat  given  off  by  burning 
petroleum  is  very  great,  and  I  have  often  used  such  a  lamp  with  advan 
tage.  If  desired,  of  course,  the  source  of  heat  used  may  be  gas,  burned 
in  a  Bunsen's  burner,  or  a  spirit-lamp ;  and  this  last,  especially  if  it  be 
supplied  with  a  metal  chimney  to  cut  off  draughts,  is,  all  things  consid 
ered,  the  best,  as  it  is  very  cleanly,  not  being  liable  to  smoke  the  bottom 
of  the  glass  or  porcelain  vessels  used.  If  we  are  going  to  work  with 
large  quantities  of  material,  we  shall  require  a  small  sand-bath  to  heat 
the  glass  vessels  upon.  In  small  quantities,  the  diatoms  may  be  boiled  in 
test-tubes,  when  some  sort  of  holder  will  be  required.  The  metal  ones, 
sold  by  dealers  in  chemists'  apparatus,  are  extremely  handy ;  but  I  have 
found  that  we  can  make  very  good  ones  out  of  old  paper  collars.  One  of 
the  kind  called  "cloth-lined"  may  be  cut  into  strips  about  three  quarters 
of  an  inch  wide  and  three  inches  long.  Such  a  strip  is  folded  around 
the  test  tube,  near  the  top,  and  the  ends,  brought  together,  are  held 
between  the  fore-finger  and  thumb.  In  this  way  the  tube  is  firmly 
grasped,  and  can  be  held  over  the  lamp  without  much  danger  of  burning 
the  hand,  as  the  paper  collar  strip  is  a  bad  conductor  of  heat;  or,  the 
paper  strip  may  be  grasped  in  an  "American  clothes-peg,"  which  has  a 
spring  to  force  its  parts  together.  Large  quantities  of  diatoms  are  best 
boiled  in  porcelain  evaporating-dishes,  glass  flasks,  or  beaker-glasses. 
The  last  mentioned  vessels  are  also  by  far  the  best  things  for  washing 
them  in.  A  few,  say  three  or  four,  glass  stirring-rods  will  be  found 
useful ;  and  one  or  two  American  clothes-pegs  to  take  hold  of  hot  evap 
orating-dishes  with.  Then  there  will  be  required  a  few  dip-tubes,  made 
of  small  glass  tube,  drawn  out  over  a  flame,  so  that  the  opening  is  con 
siderably  diminished.  The  mode  of  making  these  cannot  be  given  here, 
but  will  be  found  in  books  on  chemical  manipulation ;  and  it  will  be  well 
for  the  student  to  learn  to  make  his  own  dip-tubes,  as  a  number  will  be 
required  first  and  last,  and  they  are  easily  broken.  Of  course  there  will 
be  required  a  number  of  glass  slides,  of  the  usual  dimensions  of  three 
inches  by  one.  These  should  be  of  as  white  glass  as  possible,  and  it  will 


NATURAL    HISTORY    OF    THE    DIATOMACE^.  49! 

be  found  best  to  procure  those  with  ground  edges,  as  they  are  the  neatest 
in  appearance.  Only  such  as  are  free  from  scratches  or  other  blemishes 
in  the  central  square  inch  should  be  used ;  and,  although  even  such  as 
have  bubbles  or  scratches  near  the  ends  only  will  not  look  ornamental  in 
a  cabinet,  we  should  remember  that  microscopic  objects  are  not  generally 
mounted  to  look  well  in  a  cabinet,  but  to  be  useful  out  of  it ;  so  that  if 
the  central  and  useful  portion  of  the  slide  be  perfect  it  need  not  be 
rejected.  Some  persons  make  their  own  glass  slides,  but  I  have  never 
found  it  answer  to  do  so,  as  it  is  difficult  to  get  the  right  kind  of  glass, 
not  at  all  easy  to  cut  it  or  grind  the  edges,  and  it  is  liable  to  be  scratched 
while  cutting  or  grinding.  Thin  glass,  such  as  is  made  on  purpose  for 
microscopic  use,  will  be  required ;  and  this,  also,  it  will  be  found  best  to 
buy  ready  cut  rather  than  attempt  to  cut  it  for  one's  self.  The  thin  glass 
used  for  covers  may  be  of  different  thicknesses,  but  the  thickest  made 
will  not  do  for  diatoms,  and  a  certain  amount  of  the  very  thinnest  will  be 
required  for  small  and  delicately  marked  forms,  on  which  very  high  power 
objectives  will  have  to  be  used.  The  covers  must  be  perfectly  clean, 
which  may  be  insured  by  soaking  in  caustic  potassa  solution,  and  then 
washing  thoroughly  in  clean  water.  The  thinner  kinds  of  glass  are  rather 
difficult  to  clean ;  but  with  a  little  extra  caution  it  may  be  accomplished, 
the  last  polish  being  given  to  it  by  a  piece  of  an  old  and  well-worn  cam 
bric  handkerchief.  The  covers,  always  round,  should  be  separated  into 
sizes  and  thicknesses,  so  that  the  exact  kind  of  cover  required  can  be 
found  without  having  to  search  for  it  by  turning  over  a  number,  scratch 
ing  or  breaking  them,  and  losing  much  valuable  time.  We  shall  also 
require  a  pair  of  forceps  for  holding  the  slides  over  the  lamp ;  and  such 
as  are  sold  at  house-furnishing  stores  and  by  grocers,  under  the  name  of 
American  clothes-pegs,  and  which  have  been  already  mentioned,  are  by 
far  the  best  I  have  ever  seen  or  heard  of.  A  small  pair  of  brass  forceps 
which  close  with  a  spring  will  be  needed,  and  they  are  best  set  in  a 
wooden  handle  so  as  to  protect  the  fingers  from  the  heat ;  and  another 
pair,  which  spring  open  and  may  be  closed  by  means  of  the  finger  and 
thumb,  will  be  wanted  for  taking  hold  of  and  adjusting  the  thin  covers. 
I  do  not  advocate  the  use  of  paper  covers  for  slides,  but  labels  of  some 
kind  will,  of  course,  be  required,  and  I  have  found  the  plain  circular  white 
ones  to  look  the  best.  There  are  very  pretty  square  labels  sold  by  dealers

in  these  things  that  I  have  used  and  liked.  For  making  cells  to  hold 
specimens  put  up  in  fluid,  a  turn-table  and  brushes  and  some  cement  will 
be  necessary.  The  cement  I  use  and  prefer  above  all  others  is  good  old 
gold  size,  used  warm. 

The  chemicals  required  are  nitric  acid,  sulphuric  acid,  hydrochloric 
acid,  bichromate  of  potash,  caustic  potash,  alcohol,  and,  above  all,  a  plen 
tiful  supply  of  clean,  filtered  water.  The  water  should  be  such  as  leaves 
hardly  any  residuum  when  a  quart  of  it  is  evaporated  to  dryness ;  and  it 
must  be  filtered  just  before  use,  to  remove  any  minute  organisms,  dia 
toms  especially,  which  it  may  contain.  A  certain  amount  of  washing 
soda  will  be  wanted,  if  guanos  are  to  be  cleaned. 

We  will  now  proceed  to  consider  the  manipulations  necessary  to  pre 
pare  the  various  kinds  of  gatherings,  always  remembering  that  these 
methods  will  have  to  be  modified  to  a  certain  extent  for  each  specimen. 

Recent  GatJicrings.  If  there  be  sand  in  the  gathering,  it  will  be  well 
to  remove  it  before  using  acid  by  shaking  it  in  clean  water  and  pouring 
off  before  the  diatoms,  which  are  lighter  than  the  sand,  settle.  The 
water  holding  the  diatoms  in  suspension  may  be  poured  into  a  test-tube 
or  beaker,  the  diatoms  allowed  to  settle,  and  as  much  of  the  water 
poured  off  as  possible.  The  diatoms  are  now  covered  with  nitric  acid  to 
about  the  height  of  half  an  inch,  and  allowed  to  stand  for  a  few  minutes. 
Usually,  some  chemical  action  takes  place,  and  it  will  be  well  to  wait 
until  it  subsides.  The  test-tube  or  beaker  is  then  held  over  the  lamp 
and  carefully  heated  until  the  reaction  of  the  acid  upon  the  organic  mat 
ter  of  the  diatoms  ceases.  Thereafter,  and  while  the  liquid  is  still  hot,  I 
have  found  it  often  advantageous  to  drop  in  one  or  two  fragments  of 
bichromate  of  potash.  The  organic  matter  is  more  thoroughly  destroyed 
in  this  way  than  when  the  acid  is  used  alone.  Thereafter  it  is  well  to 
pour  the  acid  and  diatoms  into  a  capacious  beaker  of  clean  water,  wash 
ing  the  tube  or  smaller  beaker  out  with  a  little  water,  and  adding  this  to 
the  other.  After  the  diatoms  have  all  settled,  which  will  often  require 
hours,  the  supernatant  fluid  is  carefully  poured  off,  and  a  fresh  supply 
added ;  and  this  must  be  repeated  several  times  until  all  of  the  acid  and 
colored  chromium  compound  has  been  removed.  When  this  point  is 
arrived  at  can  only  be  ascertained  from  experience.  In  this  way  the 
valves  and  connecting  membranes  of  the  diatoms  are  usually  separated

and  cleaned  ready  for  mounting,  which  process  will  be  described  here 
after. 

Muds  will  have  to  be  treated  in  a  somewhat  different  manner  from 
recent  gatherings.  If  the  mud  is  dry,  it  will  have  to  be  broken  down  by 
boiling  for  a  few  minutes  in  a  solution  of  caustic  potassa,  the  strength  of 
which  must  be  apportioned  to  the  particular  specimen  under  treatment. 
After  it  has  been  broken  down  into  a  soft  mud,  all  of  the  potash  is  thor 
oughly  washed  off  by  means  of  clean  water,  and  replaced  by  nitric  acid, 
as  in  the  case  of  recent  gatherings.  This  is  boiled,  and  a  little  bichromate 
of  potash  added  as  before,  and  the  whole  washed.  It  very  seldom  hap 
pens  that  the  diatoms  occurring  in  mud  will  be  sufficiently  cleaned  by 
this  process,  so  that  it  has  to  be  supplemented  by  another.  The  sedi 
ment  is  therefore  washed  into  one  of  the  evaporating-dishes  and  allowed 
to  settle,  and  as  much  of  the  water  poured  off  as  possible.  Then  sul 
phuric  acid,  in  quantity  to  a  little  more  than  cover  them,  is  poured  in, 
and  the  vessel  gradually  and  carefully  heated.  As  soon  as  the  liquid 
shows  signs  of  boiling,  bichromate  of  potash  is  added,  a  very  little  at  a 
time,  until  the  green  color  first  formed  by  its  reaction  upon  the  organic 
matter  begins  to  assume  a  yellowish  tint,  when  no  more  is  dropped  in ; 
but  a  few  drops  of  hydrochloric  acid  are  permitted  to  fall  in,  and  the 
liquid  is  allowed  to  cool.  Of  course  it  will  be  best  if  the  person  under 
taking  to  clean  diatoms  is  somewhat  versed  in  the  use  of  chemicals ;  but 
at  any  rate  care  must  be  taken  not  to  drop  any  of  the  acids  upon  the 
clothes  or  skin,  and  great  caution  must  be  exercised  in  not  inhaling  any 
of  the  vapors  given  off.  Those  evolved  after  the  addition  of  the  hydro 
chloric  acid  are  especially  irritating  and  dangerous,  and  must  be  avoided. 
As  soon  as  the  liquid  has  cooled  a  little,  water  should  be  added  cau 
tiously,  as  great  heat  will  be  generated  thereby,  and  there  will  be  danger 
of  its  boiling  over.  Thereafter  it  may  be  poured  into  a  large  beaker- 
glass  of  water  and  thoroughly  washed,  as  in  the  former  case.  If  it  be 
found  that  the  precipitate  is  not  quite  white,  it  will  be  necessary  to  boil 
it  again  in  sulphuric  acid,  with  bichromate  of  potash  and  hydrochloric 
acid,  until  it  is  quite  clean.  If,  on  examination  by  means  of  the  micro 
scope,  it  is  found  that  there  is  much  flocculent  matter  present  besides 
the  diatoms  and  sand,  this  can  be  removed  by  boiling  for  a  few  seconds 
in  a  weak  solution  of  caustic  potash,  and  washing  quickly  and  thoroughly

with  plenty  of  clean  water.  When  we  have  recent  gatherings  of  fila 
mentous  or  stipitate  forms  of  diatomaceoe,  which  we  desire  to  preserve  in 
the  natural  condition,  they  should  be  immersed  for  about  twenty-four 
hours  in  alcohol  to  dissolve  out  the  endochrome.  If  this  does  not 
answer,  it  will  be  well  to  soak  the  mass  of  diatoms  or  plants  upon  which 
they  are  adherent  in  a  solution  of  hypochlorite  of  soda,  an  impure  variety 
of  which  is  sold  in  the  shops  under  the  name  of  Labarraque's  disin 
fectant,  for  about  the  same  length  of  time.  This  will  generally  destroy 
all  color,  and  leave  the  specimens  transparent.  It  is  best,  however,  in 
many  cases  not  to  remove  the  endochrome,  but  leave  it,  and  mount  the 
specimens  in  such  a  way  as  to  show  them  in  as  natural  a  condition  as 
possible.  How  this  may  be  done  will  be  described  hereafter. 

Guanos.  The  preparation  of  these  substances  so  as  to  obtain  the 
microscopic  organisms  they  may  contain  is  rather  difficult,  tedious,  and 
dirty,  and  should  only  be  undertaken  by  a  person  somewhat  versed  in 
chemical  manipulations,  and  in  a  proper  room  as  a  laboratory,  where 
there  is  no  danger  of  harm  resulting  from  the  fumes  evolved.  As  the 
ammoniacal  guanos  are  those  which  contain  the  most  diatoms,  and  con 
sequently  which  answer  best  to  clean,  we  will  begin  with  them,  and  take 
as  a  type  that  which  comes  from  the  islands  on  the  coast  of  Peru.  As  it 
comes  into  commerce  this  guano  is  a  moist  powder  of  a  light  iron-rust 
color,  smelling  strongly  of  ammonia,  and  having  scattered  throughout  its 
mass  lumps  of  ammoniacal  salts  of  a  more  or  less  solid  consistency. 
The  guano  should  be  thinly  spread  out  upon  a  stiff  piece  of  paper  and 
exposed  to  the  air,  and,  preferably,  to  a  moderate  heat  for  several  days  or 
even  weeks.  In  this  way  most  of  the  moisture  and  much  of  the  ammo 
nia  will  evaporate,  and  less  acid  will  be  required  to  clean  the  guano.  It 
will  now  have  become  much  lighter  in  color,  and  crumble  to  a  dry  powder. 
A  tin  pan  is  now  about  half  filled  with  a  solution  of  common  washing 
soda  in  clean  filtered  water,  and  placed  over  some  source  of  heat,  as  on 
a  stove.  The  strength  of  this  solution  is  not  a  matter  of  any  great 
moment,  and  must  vary  with  the  guano  manipulated.  As  soon  as  it 
begins  to  boil,  the  guano  is  dropped  gradually  in,  a  little  at  a  time,  while 
the  liquid  is  stirred  with  a  glass  rod  or  stick  of  wood.  Considerable 
effervescence  takes  place,  ammonia  being  given  off,  and  therefore  it  must 
be  kept  continually  stirred,  and  care  exercised  to  prevent  its  boiling  over. 


NATURAL    HISTORY    OF    THE    DIATOMACE/E.  495 

After  a  while  it  is  poured  into  a  plentiful  supply  of  clean  water  and 
washed  therewith  several  times,  care  being  taken  to  permit  all  of  the 
diatoms  to  settle.  As  soon  as  the  wash-water  is  only  slightly  colored, 
the  guano  is  transferred  to  a  good  sized  evaporating-dish,  and  covered 
with  nitric  acid,  and  boiled.  While  it  is  boiling,  a  few  crystals  of  bichro 
mate  of  potash  are  dropped  in,  and  the  material  washed  as  in  the  case 
of  muds.  Thereafter  the  diatoms  are  boiled  in  sulphuric  acid  with 
bichromate  of  potash  and  hydrochloric  acid,  as  before  described. 

Phosphatic  guanos,  as  that  from  Brazil,  are  somewhat  more  difficult  to 
treat.  They  are  generally  drier  than  the  ammoniacal  kind,  and  must  be 
boiled  in  a  large  quantity  of  hydrochloric  acid  as  many  as  three  times, 
and  the  acid  must  be  poured  off  while  still  hot.  Thereafter  nitric  acid 
and  sulphuric  acid  and  bichromate  of  potash  must  be  employed,  as  in 
the  other  case. 

Lacustrine  Sedimentary  Deposits.  For  the  most  part  these  are  pul 
verulent,  and  easy  to  clean.  Some,  as  found  in  nature,  are  so  pure  that 
they  require  no  cleaning  except  washing  in  clean  water.  Burning  on 
a  plate  of  platinum  or  mica  will  often  serve  to  clean  some  specimens, 
but  it  will,  in  general,  be  found  best  to  boil  in  nitric  acid  with  a  little 
bichromate  of  potash,  and  subsequently  in  sulphuric  acid  and  bichromate 
of  potash,  with  the  after  addition  of  hydrochloric  acid.  Occasionally  a 
certain  amount  of  flocculent  matter  will  be  left,  which  it  will  be  necessary 
to  remove  with  very  careful  heating,  not  boiling,  in  a  weak  solution  of 
caustic  potash,  and  immediately  pouring  into  a  large  quantity  of  clean 
water  and  thoroughly  washing. 

Marine  Fossil  and  Sub-Plutonic  Deposits,  being  stony  and  possessed 
of  very  much  the  same  physical  characters,  are  manipulated  in  the  same 
manner.  A  small  lump  of  the  deposit  is  placed  in  a  test-tube,  and  cov 
ered  with  a  strong  solution  of  caustic  potash.  It  is  then  boiled  for  a  few 
minutes,  and  usually  it  immediately  begins  to  break  up  and  fall  down  in 
the  shape  of  a  soft  mud-like  material.  At  once  the  liquid,  with  the  sus 
pended  fine  powder,  is  poured  off  into  a  large  quantity  of  clean  hot  water, 
and  if  the  whole  of  the  lump  has  not  broken  down  into  a  powder,  what 
remains  has  a  little  water  poured  over  it  in  the  test-tube,  and  it  is  again 
boiled.  It  will  be  found  that  a  little  more  will  now  crumble  off.  This  is 
added  to  the  rest  in  the  large  vessel,  and  if  the  lump  has  not  now  broken 


496  PHYSICAL    GEOGRAPHY. 

down,  it  is  again  boiled  in  the  alkaline  solution  and  in  water  alternately, 
until  it  has  all  been  disintegrated.  It  is  then  all  permitted  to  settle  for 
at  least  three  hours,  when  it  is  thoroughly  washed  and  boiled  in  hydro 
chloric  acid  for  about  half  an  hour.  There  is  then  added  an  equal 
amount  of  nitric  acid,  and  the  boiling  continued  for  a  short  time.  It  is 
then  washed  and  heated  in  sulphuric  acid,  with  the  addition  of  bichro 
mate  of  potash  and  hydrochloric  acid. 

All  mixed  gatherings  of  diatomaceae,  and  particularly  all  muds  and 
deposits,  should  be  separated  into  densities,  so  that  for  the  most  part  the 
larger  forms  are  collected  together,  free  from  sand,  and  separate  from 
the  smaller  species  and  broken  specimens.  This  is  done  by  using  a 
number  of  beaker  glasses,  of  various  sizes,  in  the  following  manner: 
Into  a  one-ounce  beaker  the  cleaned  diatoms  are  placed,  and  the  vessel 
filled  with  water.  It  is  then  well  stirred  up  by  means  of  a  glass  rod,  and, 
after  resting  about  five  seconds,  poured  off  carefully  into  a  six-ounce  vessel 
so  as  not  to  disturb  the  sand  which  has  settled.  Again  the  vessel  is  filled 
up  with  water,  stirred,  allowed  to  settle  for  the  same  length  of  time,  and 
poured  into  the  same  vessel.  This  is  repeated  until  it  has  been  done  at 
least  six  times,  when  we  shall  find  all  of  the  sand,  free  from  diatoms,  in  the 
small  beaker.  This  can  be  thrown  away,  and  as  soon  as  the  material  in 
the  large  beaker  has  settled  it  is  returned  to  the  small  one,  and  the  same 
process  gone  through  with,  only  extending  the  time  of  settling  now  to 
about  ten  seconds.  The  next  density  is  that  which  settles  in  twenty 
seconds ;  and  so  on,  five  or  six  densities  may  be  obtained,  and  if  carefully 
prepared  they  will  be  found  to  contain  forms  varying  very  much  one  from 
the  other.  The  large  species  of  Triceratium,  Aulacodiscus,  and  the  like, 
will  be  found  in  the  coarsest  density,  and  the  broken  diatoms  in  the 
lightest. 

Preserving  and  mounting  specimens  so  as  to  Jiavc  t/icm  in  a  condition 
for  stndy  at  any  future  time.  Of  course,  when  possible,  diatomaceae 
should  be  studied  in  the  living  condition.  But  there  are  many  forms 
which  have  not  been  as  yet  found  living,  and  these  can  only  be  studied 
as  dead  skeletons ;  and,  in  fact,  it  is  in  the  dead  skeletons  of  the  diato 
maceae  that  many  of  the  most  marked  characteristics  are  to  be  found; 
and  on  such  characteristics  species  have  been  founded.  Besides,  the 
most  beautiful  sculpturing  of  the  valves  is  only  to  be  seen  after  every- 


NATURAL    HISTORY    OF    THE    DIATOMACE^E.  497 

thincr  has  been  removed  but  the  siliceous  cell-wall  I  have  termed  the 

o 

skeleton.  Therefore  I  advocate  the  cleaning  of  a  portion  at  least  of 
every  gathering  in  the  manner  described,  so  that  nothing  will  be  left  but 
the  clean  siliceous  cell-wall. 

If  we  desire  to  keep  specimens  in  a  state  as  near  that  they  present 
when  living  as  possible,  we  have  to  put  them  up  in  some  preservative 
fluid  in  which  they  will  not  decay,  and  in  which  the  softer  parts  will  be 
preserved.  Unfortunately  these  soft  parts  do  not  keep  well;  but  the 
fluid  which  I  have  found  to  be  the  best  for  the  purpose  is  distilled  water, 
which  has  to  every  fluid  ounce  two  or  three  drops  of  wood  creosote 
added,  and  thereafter  a  sufficient  number  of  drops  of  alcohol,  which  will 
be  about  double  the  number  of  the  drops  of  creosote,  to  make  the  creo 
sote  soluble  in  the  water,  which  it  is  only  to  a  very  slight  degree  under 
ordinary  conditions.  I  do  not  advocate  any  fluid  containing  glycerine, 
or,  in  fact,  any  of  the  preservative  fluids  described  in  the  books  treating 
of  the  preparation  of  microscopic  objects.  The  vessel  in  which  the 
fresh  specimens  of  diatomaceae  are  put  up  are  what  are  known  to  micros- 
copists  as  "cells,"  but  how  these  are  made  cannot  be  gone  into  here, 
as  the  description  would  occupy  too  much  space  and  time.  Suffice  it 
to  say  that  I  prefer  cells  made  of  old  japan  gold-size,  which  can  be 
procured  of  dealers  in  microscopic  materials.  Within  such  a  cell,  of 
sufficient  depth  and  immersed  in  the  preservative  fluid,  a  few  of  the 
diatoms,  or  a  scrap  of  the  plant  upon  which  they  are  growing,  is  placed, 
and  the  glass  cover  fixed  over  it  in  the  manner  described  in  the  books 
upon  manipulation.  The  filamentous  forms  are  thus  preserved  almost  in 
their  natural  condition;  but,  on  account  of  the  presence  of  the  endo- 
chrome,  the  sculpturing  of  the  siliceous  cell-wall  is  almost  invisible.  To 
show  this  character,  while  the  filamentous  form  is  preserved,  another 
method  of  mounting  is  employed.  A  thin,  clean  covering  glass  is 
selected,  and  laid  upon  a  clean  piece  of  paper.  A  large  drop  of  distilled 
water  is  then  allowed  to  fall  upon  it,  and  in  this  drop  the  filamentous 
diatom  is  thinly  spread  out.  Then  the  cover  is  taken  up  by  means  of  a 
pair  of  forceps  and  held  over  the  flame  of  a  spirit-lamp,  which  has  been 
turned  down  so  as  to  be  quite  small  and  steady.  The  cover  is  held 
some  distance  above  the  flame,  and  judiciously  manipulated,  so  that  the 
heat  is  evenly  distributed  over  it,  and  it  does  not  crack.  As  soon  as  all 
VOL.  i.  65 


PHYSICAL    GEOGRAPHY. 

the  water  has  been  driven  off  without  the  formation  of  bubbles,  the 
glass  is  brought  gradually  down  almost  in  contact  with  the  flame,  and 
held  at  that  point  for  a  few  minutes.  Then  the  diatoms  will  be  seen  to 
turn  black,  on  account  of  the  charring  of  the  organic  matter  contained  in 
them.  After  a  while  this  black  carbonaceous  matter  will  bum  off,  and 
they  will  become  quite  white.  If,  however,  there  seems  to  be  any  diffi 
culty  in  burning  off  the  last  portions  of  carbon,  the  cover  is  lowered 
once  or  twice  to  come  in  contact  with  the  top  of  the  flame,  and  then 
raised  again.  In  this  way  it  will  become  red  hot  for  a  moment;  and 
everything  will  be  burned  off  except  the  siliceous  portions  of  the  dia 
toms.  Now  the  cover  is  removed  slowly  from  over  the  flame,  and  held 
in  the  forceps  until  it  is  cold,  but  by  no  means  laid  down  upon  any  sur 
face  until  it  is  quite  cold, — otherwise  it  will  fly  into  pieces.  Then  it  can 
be  laid  upon  an  ordinary  glass  slide,  and  examined  to  see  if  it  is  worth 
preserving,  which  may  be  done  in  one  or  two  ways:  first,  the  glass 
cover  is  warmed,  and  a  drop  of  good  spirits  of  turpentine  let  fall  upon 
it,  covering  the  diatoms.  Just  before  the  spirits  evaporate,  a  small  drop 
of  thin  Canada  balsam  is  added,  and  a  slide  taken,  warmed,  and  a  drop 
of  balsam  placed  upon  the  centre  part  of  it.  Then  the  cover  is  brought 
down  upon  the  slide,  the  two  balsam-covered  sides  together,  in  such  a 
way,  by  tilting  the  cover  slightly,  that  no  air  is  allowed  to  come  be 
tween  them,  and  the  cover  permitted  to  fall  gradually  into  place,  driv 
ing  a  wave  of  balsam  before  it.  In  this  way  we  have  the  filamentous 
diatoms  arranged  as  they  grow,  but  with  endochrome  removed  which 
would  obscure  the  markings,  and  in  balsam,  which  renders  them  trans 
parent.  Some  forms,  as  some  of  the  Fragillarice,  become  too  transparent 
if  put  up  in  this  way,  and  therefore  another  method  of  mounting  must 
be  adopted  with  them.  They  are  burned  upon  the  cover,  as  just  de 
scribed,  but  mounted  dry  in  air;  that  is  to  say,  a  cell  of  gold-size  is 
made,  the  glass  cover  slightly  warmed,  and  then  placed  upon  the  cell, 
with  the  side  upon  which  the  diatoms  are  fixed,  downwards.  The 
warmth  slightly  softens  the  gold-size,  and  the  cover  becomes  fixed. 

Other  forms  besides  the  filamentous  species  may  be  mounted  in  fluid, 
or  burned  upon  the  cover  and  subsequently  put  up  in  balsam,  or  dry. 
But  the  commonest  way  of  treating  such  forms  is  to  clean  them  by  means 
of  chemicals,  as  already  described,  and  then  previous  to  mounting  them 


NATURAL    HISTORY    OF    THE    DIATOMACEyE.  499 

divide  the  clean  gathering,  consisting  of  a  white  sediment  of  large  and 
small  diatoms  along  with  fine  sand,  all  mixed  up  together  into  densi 
ties.  Of  course,  if  some  of  this  sediment  were  to  be  mounted  in  this 
condition,  extremely  unsightly  slides  would  be  procured ;  so  it  is  best  to 
separate  the  finer  from  the  coarser  diatoms,  and  these  in  turn  from  the 
sand.  This  is  accomplished  by  what  is  known  as  elutriation,  or,  separat 
ing  into  densities  after  the  manner  already  described.  Then  slides  may 
be  mounted  from  each  of  the  densities  in  the  following  manner.  A  slide 
is  thoroughly  cleaned,  and  a  good  sized  drop  of  water  placed  upon  the 
centre  portion.  A  little  of  the  diatom  sediment  is  then  taken  up  in  a 
dip-tube,  and  the  point  of  the  tube  brought  just  into  contact  with  the 
drop.  As  soon  as  a  few  diatoms  have  run  out  of  the  dip-tube,  it  is 
removed.  Then  a  small  splinter  of  wood  or  stiff  bristle  is  used  to  dis 
seminate  the  diatoms  through  the  drop  of  water  in  such  a  way  that  they 
will  be  pretty  evenly  distributed  and  not  overlie  each  other.  The  water 
is  then  driven  off  by  heat,  a  drop  of  thin  Canada  balsam  placed  upon  the 
dry  diatoms,  and  a  cover  placed  on  them  in  the  usual  manner.  In  many 
cases,  especially  when  dealing  with  the  smaller  forms,  it  will  be  found 
desirable  to  mount  them  upon  the  cover  in  this  same  way,  instead  of  upon 
the  slide,  as  they  will  then  be  brought  as  near  as  possible  to  the  objective 
of  the  microscope.  Single  or  remarkable  specimens  of  diatoms  may  be 
picked  out  and  mounted  by  themselves  ;  but  the  manner  of  accomplishing 
this  would  occupy  more  space  than  it  has  been  thought  desirable  to 
devote  to  this  portion  of  our  subject,  and  the  reader  is  referred  to 
the  books  on  mounting  microscopic  objects  for  the  particulars  of  the 
process. 

The  main  principles  of  preparing  and  mounting  diatomaceae  for  preser 
vation  and  study  have  been  given,  and  the  intending  student  will  be  able 
to  devise  modifications  and  improvements  for  himself,  so  that  he  will  be 
able  to  put  up  specimens  in  as  finished  a  manner  as  any  to  be  procured 
from  the  dealers.

DESCRIPTION  OF  PLATES. 

All  of  the  figures,  with  the  exception  of  23  and  24,  are  magnified  five  hundred 
diameters,  or  two  hundred  and  fifty  thousand  times  superficial.  Fig.  23  is  magnified 
about  three  hundred  diameters,  and  Fig.  24  one  hundred  diameters.  All  of  the 
figures,  with  the  exception  of  the  two  mentioned,  are  exact  portraits  of  specimens  in 
the  collection  of  the  author,  and  are  intended  to  be  as  perfect  delineations  of  the 
diatoms  represented  as  could  be  obtained,  as  the  drawings  have  been  made  with 
special  care  to  that  end.  This  fact  is  mentioned,  as  most  of  the  plates  of  diatoms 
published  do  not  give  correct  ideas  of  these  organisms,  and  are  usually  drawn  or 
engraved  by  persons  not  possessed  of  an  intimate  acquaintance  with  the  objects 
intended  to  be  represented.  The  plates  have  been  obtained  by  photography  direct 
from  the  author's  drawings,  without  the  intervention  of  any  engraver,  and  are,  there 
fore,  truthful  reproductions  of  them.

APPENDIX. 


NEWARK,  N.  J.,  September  i,  1874. 
Prof.  C.  H.  HITCHCOCK,  State  Geologist : 

Dear  Sir — As  you  request,  I  send  what  information  I  can  at  the  present  time  con 
cerning  the  specimens  of  diatomaceas  which  I  have  received  from  you  or  others,  or 
collected  myself  in  the  state  of  New  Hampshire.  The  specimens  have  been  of  two 
characters.  For  the  most  part  they  have  consisted  of  lacustrine  sedimentary  deposits, 
and  these  have  been  collected  by  yourself,  or  the  other  gentlemen  connected  or  not 
connected  with  the  survey.  A  few  recent  gatherings  have  likewise  been  sent  to  me  by 
you,  or  procured  by  myself  and  a  friend,  in  and  around  Hanover  and  elsewhere.  The 
lacustrine  sedimentary  deposits  are  thirteen  in  number,  and  are  from  the  following 
localities :  Bemis  lake,  Carroll  county ;  Bowkerville,  Fitzwilliam  ;  Stamp  Act  island, 
near  Wolfeborough ;  Littleton;  Laconia;  Bristol;  Chalk  pond,  Newbury ;  Epsom; 
Pike's  pond,  Stark ;  Bow ;  Cold  pond,  2000  feet  above  the  sea,  one  eighth  mile  from 
Crawford  house;  Umbagog  lake,  Coos  county;  Concord.  Besides  these,  I  have 
received  prepared  slides  from  Manchester  and  from  Durham. 

As  it  may  be  of  interest  to  those  who  study  the  diatomaceas  to  know,  I  will  state 
when  and  how  these  deposits  came  into  my  hands. 

Bemis  Lake.  The  first  specimen  of  this  deposit  was  sent  to  me  by  Mr.  Charles 
Stodder,  of  Boston,  Mass.,  in  1859.  I  examined  it  and  published  a  list  of  the  species 
I  found  in  it  at  that  time  in  the  Proceedings  of  the  Boston  Society  of  Natural  History, 
May  2,  1860.  This  list  is  as  follows : 

Cocconema  parvum. 

Cyclotella  Kutzingiana. 

Cymbella  cuspidata. 

Eunotia  serra. 

Gomphonema  acuminatum . 

Himantidizim  gracile. 

Navicula  affinis;  Navicula  cuspidata]  Na-viculafirma',  Navicula  intcrrupta;  Nav- 
icula  rhyncocephala ;  Navicula  serians. 

Nitzschia / 

Pinnularia  major',  Pinnularia  stauroneiformis ;  Pinnularia  tabellaria',  Pinnularia 
•viridis. 

Stauroneis  phcenicenteron. 

Surirella  biseriata ;  Surirdla  linear  is. 

Tabellaria  fenestrata ;  Tabellaria  flocculosa . 

I  have  again  and  more  carefully  examined  this  deposit,  and  find  that  I  have  to  make 
some  corrections  in  the  above  list,  as  well  as  add  to  it ;  but,  as  my  investigation  has 
not  been  completed,  I  shall  not  at  the  present  time  make  these  corrections  and  addi- 


NATURAL    HISTORY    OF   THE    DIATOMACE7E.  503 

lions.  Besides  the  specimen  sent  me  by  Mr.  Stodder,  I  received  further  supplies  from 
Mr.  R.  C.  Greenleaf,  of  Boston,  in  1866,  and  from  the  discoverer  and  owner  of  the 
deposit,  Dr.  S.  A.  Bemis,  in  1865  and  1870. 

Bo-wkerville.  The  first  specimens  of  this  deposit  which  I  received  were  from  your 
self,  in  May,  1871.  In  the  following  July  I  visited  the  locality  with  you,  and  made 
further  collections. 

Stamp  Act  Island.     This  deposit  I  received  from  you  in  September,  1871. 

Littleton.  The  first  samples  of  this  deposit  were  procured  from  the  Bailey  collection 
in  the  possession  of  the  Boston  Society  of  Natural  History,  and  were  sent  me  by  Mr. 
Charles  Stodder.  Subsequently  specimens  were  sent  to  the  survey  by  Mr.  B.  W. 
Kilburn,  and  were  transmitted  by  you  to  me. 

Laconia.  The  first  specimens  of  this  I  received  from  Mr.  R.  C.  Greenleaf,  in 
November,  1865.  In  May,  1867,  he  sent  me  a  further  supply,  and  told  me  that  it 
occurred  on  a  farm  belonging  to  Col.  Crockett. 

Bristol.  This  was  sent  to  me  by  Mr.  C.  Stodder,  June,  1862,  who  said  that  he  had 
received  it  from  a  Mr.  Webster. 

Chalk  Pond,  Newbury.  A  very  small  sample  of  this  deposit  was  sent  to  me  by  you, 
October,  1871  ;  and  in  June,  1874,  you  sent  me  a  further  supply. 

Epsom.  This  I  procured  from  the  collection  of  the  Essex  Institute,  Salem,  Mass., 
in  December,  1864. 

Pike's  Pond.  This  was  discovered,  I  understand,  by  Mr.  J.  H.  Huntington,  of  the 
survey,  and  was  given  me  by  you,  June,  1871. 

Bow.  This  I  also  procured  from  the  collection  of  the  Essex  Institute,  and  it  was 
labelled  as  having  been  presented  by  Dr.  Prescott. 

Cold  Pond,  near  Crawford  House.  A  very  small  sample  of  this  was  sent  me  by  you, 
July,  1872. 

Concord.     This  I  procured  from  the  Bailey  collection  in  Boston. 

Uinbagog  Lake.     This  you  sent  me  in  July,  1870. 

The  slides  labelled  Manchester,  N.  H.,  and  Durham,  JV.  //.,  I  received  from  Mr. 
E.  Samuels,  of  Boston,  Mass. 

The  recent  gatherings  of  diatomaceae  which  I  have  from  New  Hampshire,  are  as 
follows : 
•  No.  i.  Brook  emptying  into  Shaker  pond,  Enfield. 

No.  2.  "Muck  hole,"  Hanover. 

No.  3.  On  mosses  from  Shaker  pond,  Enfield. 

No.  4.  Mink  brook,  Hanover. 

No.  5.  Trout  pond  on  farm  of  J.  E.  Lawrence,  Bowkerville. 

No.  6.  Lake  of  the  Clouds,  on  Mt.  Washington. 

No.  7.  Haystack  lake. 

No.  8.  Large  pond,  Bowkerville. 

Nos.  9,  10,  ii.     Hanover. 


504  PHYSICAL    GEOGRAPHY. 

All  of  these,  with  the  exception  of  Nos.  6  and  7,  are  my  collections.  Nos.  6  and  7 
you  sent  me. 

Besides  these  gatherings,  I  have  received  fresh-water  diatomaceae  from  the  following 
localities  in  New  Hampshire,  through  the  kindness  of  Mr.  R.  C.  Greenleaf,  of  Bos 
ton,  Mass. : 

Lake  Mouran,  on  Cannon  mountain,  1865. 

Saco  river,  1865. 

Echo  lake,  1865. 

Profile  lake,  1865. 

Spring  near  Tip-top  house,  Mt.  Washington,  1865. 

Small  pond  near  Crawford's,  1865. 

Spring  near  Lake  Mouran,  1865. 

Pond  on  Mt.  Lafayette  (Lake  Greenleaf). 

Snow  arch,  Tucket-man's  ravine. 

Androscoggin  river,  Gorham. 

Gibbs  falls,  Crawford. 

Brook  in  Bethlehem. 

In  June,  1862,  Mr.  Charles  Stodder  sent  me  a  specimen  of  a  lacustrine  sedimentary 
deposit,  labelled  "New  Hampshire:  locality  and  history  entirely  unknown;  sent  by 
some  one  in  Lawrence  to  Mr.  Ordway,  of  Manchester,  N.  H." 

In  Ehrenberg's  Mikrogeologie,  T.  XXXV,  A.  VI,  is  represented  a  deposit  of  diatom 
aceae  said  to  come  from  Perth,  N.  H.  [?],  and  this  is  mentioned  as  described  in  the 
Transactions  of  the  Berlin  Academy  for  1843.  In  tne  same  work,  T.  XXXIII,  X,  is 
represented  another  similar  deposit  from  New  Hampshire, — more  particular  locality 
not  being  mentioned.  This  is  said  to  be  described  in  the  Transactions  of  the  Berlin 
Academy  for  1845.  This  work  is  not  accessible  to  me  at  the  present  time  ;  therefore  I 
am  unable  to  give  the  particulars  mentioned  by  Ehrenberg  concerning  them. 

These,  then,  constitute  all  of  the  material  I  possess  up  to  the  present  time  represent 
ing  the  diatomaceae  of  the  state  of  New  Hampshire,  and  as  soon  as  I  shall  be  able  to 
work  up  the  forms  contained  in  them  I  will  transmit  you  a  full  report  thereon.  In  the 
meantime  it  is  extremely  desirable  that  we  should  receive  recent  collections  from  other 
parts  of  the  state ;  and  I  would  particularly  call  attention  to  the  fact  that  we  have  not, 
as  yet,  received  any  gatherings  from  brackish  or  salt-water.  Specimens  of  marine 
algae  encrusted  with  diatomaceae,  as  they  almost  always  are,  would  be  particularly 

acceptable.        Respectfully  yours, 

A.  MEAD  EDWARDS,  M.  D. 


NEWARK,  N.  J.,  September  i,  1874. 
Prof.  C.  H.  HITCHCOCK,  State  Geologist: 

Dear  Sir — I    have   thought   that   it   might   prove   of    interest   to   students   of  the 
Desmidiae  to  know  that  while  making  collections  of  diatomaceae  in  and  around  Han- 


NATURAL    HISTORY    OF    THE    DIATOMAEC/E.  $O$ 

over,  N.  H.,  in  the  summer  of  1871,  I  procured  the  following  species  belonging  to  that 
family : 

Didymoprin-ui  Borreri. 

Desniidin  in  Siuartzii. 

Microsterias  denticulata ;  Microsterias  crenata. 

Cosniariuin  Botrytis. 

Staurastruni  polyinorphum. 

Docidium  nodulosmn. 

Closteriuin  angustatuin. 

Pediastrum  Boryanuin. 

As  special  gatherings  for  obtaining  these  organisms  were  not  made,  the  above  list  is 
very  brief;  but  hereafter  I  hope  to  add  to  it,  as  the  desmidioe  of  the  United  States 
have  not  been  much  studied,  and  a  great  deal  remains  to  be  done  in  our  micro-zoology 
and  micro-phytology.  Respectfully  yours, 

A.  MEAD  EDWARDS,  M.  D. 


NEWARK,  N.  J.,  September  i,  1874. 
Prof.  C.  H.  HITCHCOCK,  State  Geologist : 

Dear  Sir — During  my  excursions  in  and  around  Hanover,  N.  H.,  three  years  since, 
in  search  of  diatomaceae,  I  collected  a  few  specimens  of  wild  plants  infested  with 
diseases  caused  by  the  growth  upon  them  and  in  their  tissues  of  microscopic  parasitic 
fungi.  These  I  submitted  to  my  friend,  Mr.  M.  C.  Cooke,  of  London,  Eng.,  the  well 
known  fungologist,  and  he  was  so  good  as  to  identify  them.  They  were  the  following : 

sEcidiiun  Viols,  Schum.,  on  wild  violet.     Viola. 

sEcidium  grossularicz,  D.  C.,  on  wild  gooseberry.     Ribes  hirtellum. 

sEcidium  Dracontii,  Schw.,  on  Indian  turnip.     Arum  triphylliim. 

sEcidiuvi  astenon,  Schw.,  on  a  plant  whose  name  was  not  ascertained. 

The  mere  announcement  of  the  discovery  of  these  species  in  New  Hampshire  will 
not  perhaps  prove  of  interest  to  the  majority  of  the  readers  of  the  survey  report ;  and 
this  will  arise  from  the  fact  that  they  will  not  be  sufficiently  informed  with  regard  to 
the  important  bearing  these  minute  plants  have  upon  the  occupation  of  the  agricul 
turist.  There  is  no  doubt  that  it  would  be  greatly  to  the  advantage  of  the  farmer  were 
he  better  informed  concerning  both  the  animals  and  vegetables  which  prey  upon  his 
crops.  If  he  knew  something  of  their  habits  and  modes  of  attack,  he  would  be  the 
better  prepared  to  resist  their  depredations,  or  even  to  attack  them  in  such  a  way  as  to 
preserve  his  crops,  and  thus  save  for  himself  much  money  and  labor.  At  some  future 
time,  and  as  further  specimens  come  into  my  hands,  I  shall  take  the  opportunity  of 
transmitting  to  you  some  remarks  on  the  fungi  injurious  to  the  crops  of  the  agricul 
turist.  In  the  mean  time,  students  of  these  plants  may  be  glad  to  know  that  those 
I  mention  have  been  found  in  New  Hampshire. 

Respectfully  yours,  A.  MEAD  EDWARDS,  M.  D.

CHAPTER    XV. 

PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE. 

HEN  the  geological  structure  of  a  territory  is  well  understood,  it 
may  be  interesting  to  review  the  changes  that  have  taken  place  in 
respect  to  its  physical  dimensions, — beginning  with  the  reclamation  of 
the  first  foot  of  dry  land  from  beneath  the  level  of  the  ocean,  and  con 
tinuing  the  sketch  with  a  description  of  the  variation  in  its  outlines, 
whether  an  enlargement  or  contraction.  Besides  the  increase  and  de 
crease  of  territory,  physical  history  may  embrace  a  notice  of  the  origin 
and  arrangement  of  the  mountain  ranges  intermittently  arising  to  view, 
changes  in  the  character  of  strata  brought  about  during  a  period  of  eleva 
tion,  the  adaptations  of  the  successive  land-surfaces  to  the  existence  of 
life,  and  other  related  topics. 

The  subject  is  a  novel  one,  as  very  few  laborers  have  wrought  in  this 
field.  Our  conclusions  have  been  drawn  entirely  from  the  induction  of 
facts  obtained  by  observation,  and  not  from  a  comparison  of  theories 
propounded  by  eminent  physicists.  Our  views  did  not  spring  into  being 
fully  developed.  At  first  only  a  glimmering  of  the  truth  appeared ;  by 
and  by  the  light  was  like  that  of  the  dawn  of  day;  then  the  skies 
became  brighter  and  brighter ; — but  I  will  not  presume  to  say  that  the 
truth  is  now  so  manifest  that  no  more  information  is  required  to  make 
the  history  perfectly  known.  The  maps  illustrating  the  successive  shapes 
of  our  territory  may  require  modification,  in  consequence  of  a  better 
knowledge  of  the  distribution  of  the  several  formations.  There  is  much 


PHYSICAL    HISTORY   OF   NEW   HAMPSHIRE.  507 

to  be  discovered  yet  in  the  southern  part  of  the  state.  Some  of  this 
information  will  be  obtained  for  our  final  geological  map.  If  the  reader 
finds  discrepancies,  he  may  accept  the  conclusions  last  stated  as  the  most 
authoritative. 

This  sketch  is  really  an  epitome  of  the  geology  of  the  state.  It  pre 
supposes  the  establishment  of  the  entire  geological  column,  the  order  of 
the  formations,  and  their  geographical  arrangement  upon  the  map.  If 
correct,  it  assumes  the  solution  of  questions  which  have  agitated  geologi 
cal  circles  for  forty  years.  We  can  only  refer  to  the  next  volume  for  the 
establishment  of  all  these  fundamental  doctrines,  and  will  state  the  sub 
ject  as  if  they  were  thoroughly  proved. 

It  is  not  desirable  to  go  further  back  in  time  than  to  the  period  of  the 
deposition  of  the  first  rock  formation  in  the  state.  There  are  interesting 
speculations  respecting  the  history  of  our  planet,  for  ages  anterior  to  its 
solidification.  It  may  have  formed  part  of  a  nebula  comprising  first 
the  entire  solar  system,  and  afterwards  only  the  earth-mass.  In  later 
times  it  is  thought  to  have  existed  in  the  condition  of  igneous  fluidity. 
A  long  series  of  ages  may  have  been  occupied  in  the  changes  which 
effected  the  formation  of  a  solid  crust,  the  falling  of  the  steam  and  vapors 
in  the  atmosphere  to  form  a  saline  ocean,  and  the  separation  of  elevated 
and  depressed  areas  from  each  other  to  allow  of  the  erosion  of  rock  and 
deposition  of  material  in  the  lower  portions.  During  much  of  this  time 
the  special  area  now  known  as  New  Hampshire  could  not  be  distin 
guished  from  the  adjoining  territory.  It  will  therefore  be  best  to  con 
fine  our  studies  to  the  time  when  dry  land  began  to  appear  within  our 
borders,  and  then  describe  the  successive  eras  of  growth  as  truthfully  as 
possible. 

At  this  point  it  is  important  to  state  the  terminology  of  our  science. 
Human  history  is  divided  into  periods,  according  to  the  supremacy  of 
various  nations  or  prominent  ideas.  Geological  history  is  classified  in 
accordance  with  the  succession  of  life,  and  the  predominance  of  particu 
lar  classes.  Four  groups  are  recognized,  i.  Eozoic,  or  the  period  of 
the  introduction  or  dawn  of  life.  2.  PALEOZOIC,  or  the  time  when 
ancient  types  of  life  predominated.  3.  MESOZOIC,  or  the  time  when  the 
middle  types  of  life  prevailed.  4.  CENOZOIC,  the  latest  period,  when  all 
will  recognize  the  recent  character  of  the  organisms. 


$O8  PHYSICAL   GEOGRAPHY. 

Of  these  great  eras,  New  Hampshire  furnishes  quite  fully  the  forma 
tions  accumulated  during  the  first,  and  somewhat  of  the  second.  After 
that,  there  are  hints  as  to  her  condition  derived  from  general  considera 
tions,  which  will  be  mentioned  in  the  proper  place.  The  Eozoic  era  is 
divided  into  the  Laurentian,  Atlantic,  Labrador,  and  Huronian  periods 
in  New  Hampshire. 

The  following  considerations  lead  us  to  believe  that  life  existed  in 
these  periods. 

i.  The  presence  of  ores  of  iron  is  an  evidence  of  the  existence  of 
vegetation.  Ores  of  iron  are  conceived  to  have  been  formed  similarly 
in  all  ages.  At  the  present  day  they  accumulate  in  swamps  and  low 
grounds  in  the  form  of  bog  ore,  or  the  hydrated  peroxide  (ferric).  To 
effect  this  deposition  the  presence  of  organic  matter  is  requisite.  The 
iron  is  present  in  the  soil  in  small  proportion,  as  the  insoluble  ferric 
oxide.  Vegetation,  when  soaked  in  water,  imparts  to  it  the  capacity  of 
dissolving  this  ferric  oxide.  A  portion  of  the  oxygen  is  given  off,  and 
the  compound  becomes  the  ferrous  oxide,  and  in  this  condition  is  readily 
soluble.  But  this  is  not  a  stable  compound  in  the  presence  of  the  atmos 
phere.  There  are  new  combinations,  and  the  soluble  ferrous,  or  protoxide, 
is  changed  to  the  insoluble  hydrated  peroxide,  and  is  precipitated,  falling 
to  the  bottom.  This  process  being  continued  indefinitely,  there  accumu 
lates  a  large  thickness  of  the  bog  ore,  oftentimes  sufficient  to  furnish 
material  for  the  smelter. 

It  is  supposed  that  most  of  the  ores  of  iron  in  every  age  have  been 
formed  in  this  way.  As  the  modern  bog  is  now  essential  to  their  pro 
duction,  so  must  there  have  been  vegetation  in  the  most  ancient  periods 
to  eliminate  the  iron. 

Furthermore,  the  Laurentian  vegetation  must  have  been  extremely 
abundant,  on  account  of  the  enormous  deposits  of  iron  ores  seen  in  the 
Adirondacks,  Ontario,  Missouri,  etc.  There  are  beds  hundreds  of  feet  in 
thickness.  This  proof  is  afforded  by  certain  beds  in  New  Hampshire,  as 
in  Lisbon  (Franconia)  and  Landaff.  The  beds  in  Bartlett  and  Gilford 
are  in  granite,  and  may  possibly  have  come  from  igneous  action,  and  if 
so  are  likely  to  be  limited  in  quantity. 

Chemical  changes  have  taken  place  in  the  original  bog  ore  in  order  to 
produce  the  magnetic  ore  of  Lisbon.  This  is  two-fold.  First,  the  water 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  509 

has  been  expelled,  perhaps  by  the  action  of  heat.  This  would  give  rise 
to  hematite  and  specular  iron,  which  differ  from  the  original  compound 
only  by  the  absence  of  water.  Second,  a  further  change,  probably  the 
continued  application  of  heat,  expels  a  part  of  the  oxygen,  producing  the 
magnetic  oxide, — a  compound  intermediate  between  the  ferrous  and  ferric 
oxides  in  respect  to  the  amount  of  oxygen  present. 

The  preparation  of  the  quartz  of  Lyndeborough  for  the  manufacture 
of  glass  illustrates  the  nature  of  the  chemical  changes  which  I  have  just 
mentioned.  The  quartz  as  taken  from  the  ledge  is  not  perfectly  pure, 
since  it  contains  a  small  per  cent,  of  ferric  oxide,  perhaps  combined  with 
water.  This  colors  green  the  vessels  manufactured  from  it,  and  therefore 
it  is  best  to  eliminate  the  iron  as  completely  as  possible,  so  as  to  secure  a 
better  quality  of  glass.  The  rock  is  put  into  a  kiln  and  burnt,  just  as  if 
it  were  limestone  being  converted  into  lime.  The  rock  becomes  friable, 
so  that  it  can  be  readily  crushed  and  pulverized,  and  the  iron  is  converted 
into  the  magnetic  oxide.  After  pulverization,  the  quartz-flour  is  made  to 
fall  in  a  stream  over  magnets  set  like  bristles  on  the  surface  of  cylinders. 
The  magnets  instantly  attract  the  iron  sand,  which  is  thus  perfectly 
removed  from  the  quartz  by  several  repetitions  of  the  process  of  falling 
over  the  revolving  cylinder.  Had  not  the  fire  removed  the  water  and  a 
portion  of  the  oxygen  from  the  iron  ore,  the  magnets  could  not  purify 
the  quartz.  The  change  is  precisely  like  that  which  has  taken  place  in 
the  magnetization  of  the  Laurentian  ore-beds,  and  hence  it  is  reasonable 
to  suppose  that  nature  has  done  the  same  work  upon  a  large  scale  which 
may  be  often  witnessed  at  the  Lyndeborough  glass-works. 

2.  The  presence  of  graphite,  plumbago  or  black-lead  in  the  Eozoic 
rocks  is  evidence  of  the  former  existence  of  vegetation.  We  do  not  yet 
know  how  to  account  for  the  existence  of  graphite  in  the  earth,  except 
through  plants.  Great  changes  have  been  effected  in  its  mass,  so  as  to 
have  entirely  altered  its  nature.  Instead  of  being  combustible,  it  is  one 
of  the  most  refractory  substances  known,  and  is  largely  used  for  the 
manufacture  of  crucibles  in  which  metals  are  fused.  No  one  has  yet 
detected  any  traces  of  vegetable  structure  in  graphite,  so  that  we  have 
no  evidence  from  morphology  of  the  nature  of  the  earliest  plants.  From 
general  considerations,  we  may  believe  them  to  have  been  algae,  fungi,  or 
lichens,  perhaps,  of  giant  forms  and  of  particular  shapes  not  represented 


5IO  PHYSICAL    GEOGRAPHY. 

in  living  nature.     Our  rocks  afford  graphite  in  abundance,  and  hence 
suggest  the  presence  of  plants  in  New  Hampshire  in  the  earlier  periods. 

3.  Some  argue  the  presence  of   animal  life  in  the  older  rocks,  on 
account  of  the  presence  in  them  of  limestone.     It  is  said  that  all  lime 
stone  found  in  stratified  rocks  has  been  derived  from  the  decay  of  the 
shells  of  marine  animals  or  other  organisms.     If  this  be  true,  it  is  certain 
that  organisms  once  flourished  in  our  state,  as  we  have  an  abundance  of 
Eozoic  limestone  in  Lisbon,  Haverhill,  Amherst,  etc.     The  argument  is 
not  a  strong  one,  since  many  thermal  waters  are  constantly  depositing 
tufa,  oftentimes  in  massive  beds. 

4.  Animal  life  is  thought  to  have  been  abundant,  because  of  the  pres 
ence  of   the  Eozoon  in  the  Laurentian  of    New  York,  Massachusetts, 
Ontario,  and  elsewhere.     In  1858,  J.  McMullen,  an  explorer  attached  to 
the  geological  survey  of  Canada,  brought  specimens  from  the  Laurentian 
limestones  of  Ontario  to  Sir  W.  E.  Logan,  the  director  of  the  survey, 
which  had  an  organic  appearance.     The  first  examinations  did  not  reveal 
anything  like  organic  remains,  though  Sir  William  believed  they  must 
be  the  relics  of   life.     They  were  exhibited   to  the  geologists    at  the 
Springfield  meeting  of  the  American  Association  for  the  Advancement 
of  Science,  in  1859.     ^n  February,  1865,  a  series  of  papers  appeared  in 
the  Quarterly  Journal  of  the  Geological  Society  of  London,  by  Sir  W. 
E.  Logan,  Dr.  J.  W.  Dawson,  Dr.  W.  B.  Carpenter,  and  T.  Sterry  Hunt, 
wherein  arguments  were  set  forth  in  favor  of  the  foraminiferal  character 
of  the  supposed  organisms,  to  which  the  name  of  Eozoon  Canadense 
was  given  by  Dr.  Dawson.     This  proposal  called  out  investigations  in 
various  quarters, — some  in  favor  of  the  Canadian  theory,  and  others  in 
opposition  to  it.     Those  best  acquainted  with  the  recent  forms  of  the 
foraminifera  usually  believe  that  this  Eozoon  is  of  organic  origin ;  those 
who  disbelieve  the  organic  theory  are  mostly  better  skilled  in  mineralogy 
than  biology.     The  discussion  is  still  warmly  pressed ;  and  it  is  not  judi 
cious  to  quote  the  existence  of  this  possible  organism  as  satisfactory 
proof   of  the  presence  of  animal  life  in  the  Laurentian.     The  author, 
however,  is  satisfied  with  the  arguments  urged  in  favor  of  its  organic 
nature  ; — the  more  readily,  since  two  of  the  considerations  previously 
stated  afford  a  substantial  basis  for  the  existence  of  plant-life  during 
the  same  early  period. 


PHYSICAL    HISTORY   OF    NEW    HAMPSHIRE.  51  I 

The  terms  Azoic,  without  life,  and  Hypozoic,  beneath  life,  are  still  applicable  to  the 
stratigraphical  systems  which  flourished  antecedently  to  the  Laurentian,  but  they  are 
not  appropriate  designations  for  any  of  the  crystalline  strata  which  are  now  referred  to 
the  Eozoic.  If  it  be  objected  that  many  will  still  understand  these  terms  in  their 
former  acceptation,  it  may  be  answered,  that,  when  properly  informed,  such  persons 
will  more  easily  understand  the  shifting  of  the  designation  than  the  proposal  of  a  new 
name.  For  the  past  twenty-five  years  many  groups  of  strata  had  been  removed  from 
the  Azoic  system  without  giving  rise  to  any  misunderstanding.  Furthermore,  no  one 
is  yet  able  to  point  to  any  locality  where  these  most  ancient  systems  crop  out ;  hence 
the  liability  to  misconception  is  greatly  reduced.  The  Azoic  rocks,  as  now  under 
stood,  are  limited  at  their  top  by  the  Laurentian  system,  and  at  the  bottom  by  the  very 
beginning  of  deposition.  If  we  grant  the  existence  of  animals  in  the  Laurentian,  and 
follow  out  the  analogies  derived  from  the  development  of  the  higher  from  the  lower 
forms  of  life, — animals  succeeding  plants, — then  there  must  have  been  an  immensely 
long  period  antecedent  to  the  Laurentian,  characterized  as  the  Eophytic,  or  the  dawn 
of  plant-life.  This  system,  if  ever  discovered,  will  be  entitled  to  a  place  by  the  side 
of  the  four  great  divisions  specified  above. 

The  name  Eozoic  seems  to  have  been  proposed  by  Dr.  J.  W.  Dawson,  of  Mon 
treal,  in  1865.  He  did  not  fully  define  the  limits  of  its  application  at  that  time  ;  but  it 
seems  to  have  been  generally  understood  by  geologists  to  embrace  all  the  obscurely 
fossiliferous  rocks  older  than  the  Cambrian.  The  considerations  just  stated,  showing 
that  our  crystalline  rocks  contain  obscure  evidences  of  life,  make  it  plain  that  the 
Eozoic  system  is  a  natural  one,  characterized  by  very  scanty  traces  of  organisms.  Its 
separation,  as  a  system,  from  those  beneath  entirely  devoid  of  life,  is  also  natural,  and 
in  accordance  with  the  most  approved  geological  usage.* 

THE  FIRST  DRY  LAND  IN  NEW  HAMPSHIRE. 

Accepting  as  a  fact  the  doctrine  that  the  whole  globe  was  entirely 
covered  over  by  the  ocean  before  the  beginning  of  the  deposition  of 

*  The  recent  proposal  by  Prof.  J.  D.  Dana,  in  the  second  edition  of  his  Manual  of  Geology,  to  call  both  the 
Azoic  and  Eozoic  systems  Archtean,  the  beginning  rocks,  seems  uncalled  for,  but  would  be  less  objectionable  if 
the  author's  own  definition  was  strictly  adhered  to.  The  distinctions  given  between  the  Azoic  and  Eozoic  are 
not  incompatible  with  those  stated  in  the  text  above ;  but  the  word  Archtpan  is  nearly  universally  used  in  the  sense 
of  Eozoic  throughout  the  Manual.  On  page  140,  in  giving  the  subdivisions  of  all  geological  time,  he  says, — 
"  ARCHAEAN  TIME,  including  an  Azoic  and  an  Eozoic  era,  though  not  yet  distinguished  in  the  rocks,  i.  Azoic 
Age.  2.  Eozoic  Age."  On  page  148,  reference  is  made  to  Dawson's  suggestion  of  the  word  Eozoic  in  place  of 
Azoic,  with  the  opinion  that  its  use  is  objectionable,  because  the  supposed  Eozoon  may  be  of  mineral  nature. 
On  page  151,  the  Archaean  Era  is  divided  into  the  two  periods,  Laurentian  and  Huronian.  The  word  Archaean, 
on  page  151,  seems  to  be  synonymous  with  Eozoic,  on  page  140.  I  do  not  suppose  the  use  of  the  word  Eozoic 
implies  belief  in  the  existence  of  the  animal  Eozoon.  The  adjective  to  be  used  in  that  sense  would  be  Eozoonal. 
The  distinction  between  the  true  Azoic  and  Eozoic  ages  is  of  greater  import  than  between  any  other  two  of  those 
used  to  mark  geological  time  ;  and  hence  the  union  of  them  under  one  designation  is  uncalled  for.  Furthermore, 
Dawson's  name  has  the  advantage  of  several  years'  prior  suggestion  and  general  usage  among  geologists.  It  is 
also  undesirable  to  break  up  the  unity  of  the  terminology  of  the  great  ages  of  the  world's  history  by  adopting  a 
term  not  having  the  termination  of  zoic.  For  these  and  other  reasons,  it  does  not  seem  to  be  for  the  good  of  the 
science  to  substitute  Archaean  for  Eozoic  in  geological  literature.

sediments,  we  look  in  vain  over  the  broad  expanse  of  waters  for  any 
landmark  to  indicate  the  boundaries  of  New  Hampshire  or  the  neigh 
boring  states.  Towards  the  close  of  this  epoch,  and  probably  after  the 
formation  of  large  islands  to  the  north  in  Canada,  and  to  the  west  in 
New  York  (Adirondack  region),  oceanic  currents  began  to  accumulate 
sediments  in  the  shallower  places.  After  a  while  these  masses  attained 
large  dimensions ;  and  the  operation  of  igneous  forces  beneath  brought 
to  the  surface  an  archipelago  of  islands,  perhaps  thirty  in  number. 
These  constituted  the  first  areas  of  dry  land  in  New  Hampshire.  The 
position  and  shapes  of  these  islands,  as  the  rock  composing  them  now 
crops  out,  are  shown  in  the  first  of  our  series  of  illustrations. 

These  islands  were  probably  composed  of  clay  and  sand.  The  clay 
may  have  come  from  the  decomposition  of  still  earlier  feldspathic  rocks, 
possibly  the  original  crust  of  the  earth.  The  sand  may  have  been 
washed  from  some  of  the  primeval  piles  of  superfluous  silica,  which 
found  no  congenial  element  with  which  to  unite  in  the  world-making 
process.  As  these  areas  are  now  examined,  they  seem  to  be  composed 
chiefly  of  porphyritic  granite  or  gneiss,  which,  to  ordinary  eyes,  appear 
to  be  very  unlike  clay  and  sand.  Is  it  possible  that  the  sediments  have 
been  altered  into  these  crystalline  aggregates  ? 

The  answer  to  this  question  involves  propositions  the  most  difficult  of 
any  in  our  science  to  be  lucidly  explained.  It  is  only  sufficient  now  to 
state  our  theory.  These  primeval  deposits  of  sand  and  clay,  by  the 
action  of  steam,  heat,  and  chemical  agents,  have  been  changed  into 
gneiss  and  granite.  The  large  crystals  of  feldspar  and  the  scales  of 
mica  are  the  products  of  the  alteration  of  clay.  The  sediments  are  sup 
posed  to  have  been  rendered  soft  and  plastic  through  heat  and  steam ; 
and  chemical  affinities  have  collected  together,  from  a  heterogeneous 
mass,  all  the  elements  required  to  form  the  two  crystalline  minerals. 
After  their  crystallization,  the  residuum,  consisting  of  amorphous  silica, 
sought  the  crevices  between  the  newly  formed  minerals,  became  closely 
packed  because  of  a  considerable  pressure  crowding  the  mass,  and  have 
had  no  opportunity  of  assuming  the  geometrical  shapes  forming  when 
the  quartz  is  situated  in  favorable  situations.  This  change  is  known  as 
metamorphism. 

The  resultant  rock  attracts  attention  by  its  spotted  appearance.     One

of  the  finest  exposures  of  it  lies  in  the  towns  of  New  Hampton  and 
Meredith.  At  Lake  Village  it  is  the  most  common  stone  used  for  under 
pinning.  Along  the  Boston,  Concord  &  Montreal  Railroad,  from  Ashland 
to  Lake  Village,  ledges  of  it  are  frequent ;  also,  along  the  Northern  Rail 
road,  between  West  Andovcr  and  East  Canaan.  The  rock  is  grayish, 
rarely  dark  brown,  with  rectangular  spots  thickly  scattered  over  it  vary 
ing  in  size  from  one  fourth  of  one  to  two  or  three  inches  long,  and  a 
fourth  part  as  wide.  These  crystals  of  feldspar  are  sometimes  arranged 
in  lines,  their  longer  axes  being  parallel  one  to  another,  or  they  may  be 
thrown  together  indiscriminately.  This  difference  in  arrangement  indi 
cates,  perhaps,  the  degree  of  intensity  with  which  heat  has  acted  upon 
the  rock.  The  first  are  akin  to  strata  of  gneiss ;  the  second  is  a  granite, 
resulting  from  the  aqueo-igneous  fusion  of  the  first.  The  fusion  must 
have  been  protracted  and  the  material  very  plastic,  in  order  to  permit 
the  development  of  such  large  and  abundant  crystals. 

It  is  probable  that  some  of  these  islands  were  united  at  this  first  time 
of  elevation,  though  they  are  now  separated  by  other  material  of  later 
origin,  formed  partly  from  the  degradation  of  the  former,  and  deposited 
upon  it.  There  has  been  much  crowding  of  the  older  rocks  in  subsequent 
periods,  so  as  to  compress  what  may  have  been  a  large  island  at  first  into 
an  insignificant  patch.  It  would  not  be  surprising  if  this  archipelago 
originally  covered  as  much  area  as  the  two  states  of  New  Hampshire 
and  Vermont  combined.  Our  representation  must  therefore  fall  some 
what  below  actual  truth.  The  widest  stretch  of  the  imagination  can 
mark  out  a  possible  arrangement  of  these  primeval  areas,  but  it  would 
not  satisfy  the  mind  so  well  as  the  delineation  of  their  present  limits. 
With  this  explanation  presented,  the  reader  may  conceive  the  separation 
of  these  areas  over  a  greater  range  of  longitude  than  is  permissible 
within  the  present  state  limits.  There  would  not  be  much  variation  in 
the  length,  as  the  crowding  in  later  times  came  from  the  east  or  west. 

This  archipelago  must  have  been  considerably  isolated  from  every 
other  existing  territory  in  this  ancient  period,  since  we  must  go  a  long 
way  in  any  direction  to  find  the  same  formation.  It  is  entirely  unknown 
in  Vermont,  but  crops  out  in  the  Adirondacks,  and  north  of  the  St.  Law 
rence,  in  Canada.  Very  little  is  known  of  the  rocks  in  western  Maine, 

so  that  it  cannot  positively  be  said  to  be  wanting  there,  though  I  have

discovered  no  traces  of  this  formation  west  of  Prospect  and  Frankfort, 
on  the  Penobscot  river,  except  near  Mt.  Bigelovv.  East  of  the  Penobscot 
it  is  as  abundant  as  in  New  Hampshire.  Southerly  the  formation  prob 
ably  extends  through  Massachusetts  into  Connecticut,  along  the  western 
portion  of  Worcester  county. 

It  would  appear,  therefore,  that  in  New  Hampshire  and  Massachusetts, 
at  the  close  of  the  first  great  period,  there  was  a  long  sandy  ridge,  corre 
sponding  to  the  distribution  of  the  porphyritic  granite,  while,  along  the 
Green  Mountains  and  in  western  Maine,  the  ocean  concealed  everything 
from  view.  It  is  likely  that  there  is  now,  beneath  the  intervening  strata, 
a  continuous  sheet  of  this  porphyritic  rock  connecting  the  New  York, 
New  Hampshire,  and  Maine  outcrops,  which,  in  the  early  era,  consti 
tuted  the  bottom  of  the  ocean.  Dredging  machines  would  have  found 
nothing  all  over  this  floor  different  from  the  porphyritic  sediment. 

A  study  of  the  map  will  show  a  few  matters  of  interest  in  respect  to 
the  distribution  of  this  formation:  First,  no  land  existed  thus  early 
north  of  Whitefield.  Second,  there  are  two  principal  ranges.  The 
most  important  commences  in  Whitefield,  runs  to  Franconia,  Moosilauke 
(not  the  summit),  Groton,  Mt.  Cardigan,  Grafton,  and  so  on  continuously 
to  Jaffrey,  and  probably  is  the  same  with  the  Chesterfield  and  Winches 
ter  island.  The  next  starts  from  the  south  base  of  Mt.  Carrigain,  east 
of  Lincoln,  is  strongly  developed  in  Waterville,  Sandwich,  New  Hamp 
ton,  Meredith,  etc.,  and  follows  the  south-west  border  of  Lake  Winni- 
piseogee  into  New  Durham.  Third,  this  lake  range  is  remarkable  for 
its  curvatures.  Proceeding  southerly,  it  makes  a  sharp  turn  in  New 
Hampton,  runs  back  northerly  to  Squam  lake,  and  then  folds  back  on 
itself  like  the  barb  of  a  fish-hook,  and  assumes  a  south-easterly  course 
(p.  55).  Before  discovering  the  fact  of  these  curvatures,  I  had  erro 
neously  represented  the  Waterville  range  as  continuous  to  Dublin. 
Fourth,  the  principal  range  lies  along  the  line  of  greatest  elevation  in 
the  state  (pp.  210,  211),  or  the  water-shed  between  the  Connecticut  and 
Merrimack  rivers.  The  most  northern  area  attains  the  altitude  of  about 
1600  feet,  the  lowest  part  being  about  1000  feet.  The  Franconia-Rum- 
ney  area  shows  the  rock  as  high  as  4300  feet.  The  higher  points  are 
Lake  of  the  Clouds,  Mt.  Lafayette,  over  4000  feet ;  Mt.  Kinsman,  4300 ; 
Blue  ridge,  2000;  hills  in  Ellsworth  and  Rumney,  probably  1800  feet. 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  515 

The  Groton-Jaffrey  range  gives  us  Mt.  Cardigan,  3156  feet;  hills  in  Graf- 
ton,  nearly  2000;  line  of  railroad  from  West  Andover  to  Grafton,  677 
to  about  900 ;  Mt.  Sunapee,  2683  ;  Mt.  Lovell,  2487.  The  southern  end 
of  the  area  is  more  than  1000  feet  above  the  sea.  Fifth,  there  is  a 
group  of  islands  in  Warner,  Salisbury,  Webster,  Hopkinton,  and  Hen- 
niker,  connected  with  the  end  of  a  promontory  trending  north-easterly 
from  the  main  range  at  Hillsborough.  Sixth,  a  conspicuous  line  of 
islands  reaches  from  the  north  part  of  Webster,  through  Hopkinton  and 
Weare,  into  New  Boston,  over  twenty  miles  long,  and  curved  like  a  bow. 
Seventh,  possibly  the  Pelham  and  Seabrook  islands,  represented  on 
north-east  range  along  the  Massachusetts  border.  Eighth,  it  is  notice 
able  that  the  northern  ends  of  the  principal  ranges  sink  beneath  the 
higher  White  Mountains,  and  have  not  yet  been  discovered  to  the  north 
of  them  in  New  Hampshire,  though  appearing  east  of  Mt.  Bigelow  in 
Maine,*  ninety  miles  or  more  north-easterly  from  Mt.  Carrigain. 

ADDITIONS  DURING  THE  ATLANTIC  PERIOD. 

At  the  close  of  the  Atlantic  Period  the  area  of  dry  land  was  very 
considerable,  occupying  fully  two  thirds  of  the  present  state  limits.  In 
general  terms,  this  area  may  be  said  to  be  central,  the  portions  not  filled 
out  being  at  the  extreme  north,  on  the  sea  coast,  and  along  the  Con 
necticut  valley.  The  flanks  of  the  principal  porphyritic  formation  are 
covered,  and  much  of  the  space  between  the  primitive  islands  is  filled  up. 
The  rock  is  also  very  commonly  a  gneiss. 

Several  important  events  are  indicated  by  the  succession  of  deposits. 
I  give  them  as  seems  in  best  agreement  with  the  facts  as  now  understood. 
First,  and  lowest  down,  are  rather  local  deposits  of  a  somewhat  talcose 
gneiss,  receiving  the  name  of  Bethlehem  group,  from  the  locality  where 
its  features  are  best  displayed.  Second,  Winnipiseogec  lake  (or,  for 
short,  Lake  gneiss).  I  think  this  includes  the  Berlin  and  Manchester 
ranges,  mentioned  in  some  previous  publications.  Third,  Montalban,  or 
White  Mountain  series.  Fourth,  Franconia  breccia  group.  It  is  not 
needful  to  distinguish  these  formations  on  the  map  at  present,  and  the 
second  of  our  map-illustrations  merely  shows  the  whole  system  as  it 
stands  related  to  the  preceding  areas.

5l6  PHYSICAL    GEOGRAPHY. 

Several  features  of  this  distribution  are  interesting.  First,  the  rocks 
have  a  general  north-east  south-west  course.  Second,  they  occupy  the 
spaces  adjacent  to  and  between  the  first  areas  of  dry  land,  just  as  we 
should  naturally  expect  if  the  additions  have  been  made  to  nuclei.  A 
more  careful  study  of  the  arrangement  shows  that  the  same  succession 
of  formations  is  observed  in  traversing  either  flank  of  the  porphyritic 
group.  The  same  member  touches  both  sides  of  the  porphyritic  area; 
the  second  lies  adjacent  to  the  first  in  each  direction ;  the  third  is  along 
side  the  second,  connecting  laterally, — and  so  on.  Third,  there  are 
several  smaller  areas  of  this  age  in  the  neighborhood.  One  occupies 
Odell  and  vicinity.  Another  ranges  through  Essex  county,  Vt,  and 
probably  exists  as  an  underground  ridge  from  Concord,  Vt.,  to  Reading, 
Vt.,  where  it  seems  to  reappear  and  extend  nearly  to  Massachusetts  along 
the  same  course.  Small  areas  are  situated  about  Bellows  Falls  and  Pel- 
ham.  Another  of  great  importance  is  the  Green  Mountain  gneiss  of 
Vermont.  The  main  range  of  New  Hampshire  stops  short  of  the  Ken- 
nebec  river,  in  a  north-easterly  direction,  but  seems  to  reappear  on  the 
south-east  in  an  extensive  area  between  York  and  Hancock  counties  in 
Maine.  Fourth,  this  formation  occupied  several  areas  at  the  close  of  the 
Atlantic  age,  which  were  .concealed  by  the  deposits  of  later  eras.  Such 
are  the  Pemigewasset  district  at  the  White  Mountains,  and  considerable 
parts  of  Carroll,  Strafford,  and  Merrimack  counties.  It  is  to  be  pre 
sumed,  also,  that  the  most  distant  areas,  as  the  Green  Mountains,  and 
coast  of  Maine  districts,  are  connected  directly  with  the  New  Hamp 
shire  deposits  by  a  sheet  of  sediments  which  bend  down  deeply  into  the 
earth,  directly  overlying  the  porphyritic  gneisses  of  the  first  period. 
The  space  between  the  White  and  Green  Mountains  might  then  be 
regarded  as  a  great  basin,  or  synclinal,  held  up  by  the  porphyritic  cup, 
and  itself  sustaining  various  newer  sheets  of  rock.  Fifth,  the  general 
height  of  the  Atlantic  rocks  corresponds  well  with  the  average  elevation 
of  the  state  above  tide-water,  except, — Sixth,  the  Mt.  Washington  range 
from  the  Saco  valley  to  Mt.  Bigelow  in  Maine.  Its  greater  height  is 
probably  due  to  additional  elevations  in  later  periods,  while  there  is 
reason  to  believe  that  it  was  raised  to  an  unusual  height  at  this  time. 

Considered  historically,  the  following  notable  events  occurred  during 
the  Atlantic  period:  i.  There  was  a  deposition  of  sediments  between

Berlin  and  Lebanon,  chiefly  in  the  Connecticut  valley  and  in  Carroll 
county,  of  sandy  grits,  which  we  know  in  the  altered  state  as  the  BctJilc- 
Jicni  group.  2.  It  is  likely  that  these  strata  were  elevated  and  metamor 
phosed  at  the  close  of  this  era.  3.  The  very  extensive  deposits  of  the 
Lake  gneiss  formation  were  next  laid  down.  The  largest  amount  of  them 
underlie  the  hydrographic  basin  of  Winnipiseogee  lake,  and  follow  the 
porphyritic  band  south-westerly  towards  Peterborough.  The  same  group 
extends  from  southern  Cheshire  county,  through  Sullivan  and  Grafton 
counties,  to  Milan,  and  also  from  Mason  to  Deerfield,  through  Man 
chester.  4.  Nearly  all  the  rest  of  the  Atlantic  area,  or  the  Montalbau 
group,  was  next  deposited.  The  rocks  are  of  two  or  three  kinds.  There 
is  a  gneiss,  largely  deficient  in  feldspar,  containing  crystals  of  andalusite 
in  abundance.  This  characterizes  the  principal  White  Mountain  sum 
mits.  A  second  variety  is  excessively  ferruginous  upon  decomposition. 
A  third  is  the  well  known  "granite"  of  Concord,  Plymouth,  Farmington, 
Milford,  Fitzwilliam,  Troy,  Maryborough,  etc.  It  is  really  a  stratified 
rock,  whose  divisional  planes  can  be  detected  only  with  great  difficulty. 
There  must  have  been  variations  in  the  conditions  of  deposit  to  insure 
the  accumulation  of  sediments  that  should  alter  into  schists  so  diverse 
from  each  other  as  these.  5.  Next  came  the  ejection  of  the  granitic 
mass,  giving  rise  to  the  Franconia  breccia.  This  igneous  rock  is  com 
pletely  filled  with  masses  of  all  the  formations  that  have  been  described 
thus  far,  but  carries  none  of  those  that  succeed.  Hence  it  seems  to 
have  been  connected  with  the  great  series  of  disturbances  closing  the 
long  period  of  quiet  Atlantic  deposition.  This  rock  covers  a  few  square 
miles  in  Franconia,  and  may  be  repeated  in  Granby,  Vt.,  and  possibly  at 
one  or  two  places  along  the  Connecticut  valley.  The  paste  of  the  breccia 
is  mostly  feldspathic  in  its  mineral  constitution.  6.  Next  came  probably 
the  greatest  period  of  disturbance  and  elevation  known  in  the  whole  his 
tory  of  New  Hampshire.  The  White  and  Green  mountains  came  into 
being,  and,  most  likely,  the  whole  system  of  Atlantic  mountains,  from  Can 
ada  to  Alabama.  They  may  not  have  assumed  their  present  elevation  at 
this  time,  but  became  a  marked  feature  in  the  primeval  landscape,  and 
prominent  objects  for  the  action  of  the  atmospheric  elements,  breaking 
down  and  washing  away  all  jutting  out  points.  In  connection  with  the 
elevation,  the  sedimentary  strata  became  converted  into  crystalline  schists. 


5l8  PHYSICAL    GEOGRAPHY. 

This  grand  event  closed  the  Atlantic  period.  Its  importance  demands 
some  further  notice  of  the  action  of  the  forces  producing  elevation,  and 
the  process  of  metamorphism. 

THE  ELEVATING  FORCES. 

Many  persons  think  a  mountain  is  elevated  by  some  force  or  agent 
situated  directly  underneath,  and  that  the  thrust  is  upwards,  and  the 
mass  of  matter  retained  in  place  by  an  injection  of  molten  matter.  It  is 
difficult  to  comprehend  how  any  such  action  can  have  taken  place  on  a 
large  scale ;  and  hence  we  must  avail  ourselves  of  quite  a  different  theory. 
Its  general  application  can  be  perfectly  understood  by  reference  to  an 
action  common  in  the  winter  throughout  the  Northern  states. 

When  snow  covers  the  ground,  it  is  easy  to  push  it  away  from  a  given 
area;  but  a  ridge  is  built  up  just  on  the  edge  of  the  cleared  walk.  Sup 
pose  our  assistant  takes  a  pole,  fastens  it  into  the  centre  of  a  piece  of 
board,  one  foot  high  and  three  feet  long.  A  single  effort  will  enable  him 
to  clear  a  space  three  feet  wide  by  pushing  the  board  away  from  him. 
If  three  hundred  men,  each  armed  with  a  similar  snow-pusher,  should 
act  simultaneously  along  a  sidewalk  nine  hundred  feet  long,  there  would 
suddenly  start  into  being  a  ridge  of  snow  nine  hundred  feet  in  length. 
The  force  of  elevation  in  this  case  is  a  lateral  one,  and  it  accomplishes 
the  same  result  as  if  some  power  had  acted  upwards  from  beneath  along 
the  same  line.  Now  our  theory  supposes  the  existence  of  a  mighty  force 
acting  laterally  along  the  whole  length  of  the  Atlantic  formation,  from 
Canada  to  Alabama,  in  the  same  way  that  the  ridge  of  snow  was  ele 
vated.  The  power  displayed  is  great  enough  to  shove  along  the  thick, 
horizontal  sheet  of  sediments ;  and,  where  the  substratum  is  firm,  to 
fold  up  a  mountain  range  resting  upon  durable  foundations.  In  case  the 
floor  is  yielding  alongside  of  the  range,  a  valley  would  be  formed  parallel 
with  the  mountain.  If  the  foundation  is  unyielding,  there  will  still 
naturally  be  depressions  or  valleys  between  the  mountain  ranges. 

The  origin  of  this  lateral  force  is  suggested  by  certain  geological 
features  of  our  vicinity,  and  general  theoretical  considerations,  i.  Given 
the  existence  of  the  parallel  older  ridges  of  the  Penobscot  district  in 
Maine,  the  primeval  archipelago  in  New  Hampshire,  and  the  Adiron 
dack  hills  in  New  York,  and  grant  that  some  energy  causes  them  to 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  519 

approach  each  other,  we  can  see  that  the  Atlantic  schists  between  would 
be  crowded  by  lateral  forces  so  as  to  produce  mountains,  if  the  pressure 
be  sufficiently  great.  It  would  not  be  easy  in  this  case  to  say  that  the 
force  came  from  the  south-east  or  from  the  north-west,  but  practically 
from  both  quarters.  If  the  Profile-Sunapee  porphyritic  range  were 
moved  north-westerly,  it  might  not  be  more  influential  in  folding  up  the 
Green  Mountains  than  the  Adirondacks,  since  their  power  of  resist 
ance  is  practically  an  energy  pushing  in  the  opposite  direction.  It  has 
been  common  among  geologists  to  argue  that  the  pressure  inducing 
elevation  in  North  America  has  come  mainly  from  the  south-east,  or 
from  the  ocean  towards  the  interior;  but  in  the  present  case  there  is 
certainly  reason  to  believe  that  the  force  has  come  as  much  from  one  as 
from  the  other  quarter.  2.  Accepting  the  doctrine  of  the  earth's  refrig 
eration  from  the  condition  of  igneous  fluidity,  it  is  easy  to  understand 
why  parallel  ridges  should  be  made  to  approximate  to  each  other,  and 
consequently  in  their  motion  crumple  up  the  thick  rock  masses  lying 
between  them.  In  cooling,  a  crust  forms  over  an  igneous  interior.  This 
crust  eventually  becomes  so  large  that  it  cannot  fit  the  nucleus  within  it, 
and  hence  there  must  be  a  bending  of  the  stiff  envelope  to  bring  the  two 
parts  together.  The  crust  cannot  possibly  fit  the  interior  save  by  sinking 
down  almost  everywhere,  and  rising  along  a  few  lines,  so  as  to  make 
ridges  on  the  surface.  The  process  of  shrinkage  and  ridging  by  the 
close  of  the  Atlantic  period  may  be  supposed  to  have  been  carried  on  so 
far  that  the  three  parallel  lines  of  land  just  spoken  of  correspond  to  three 
elevated  lines  on  the  surface  of  the  earth's  crust.  The  process  of  cool 
ing  had  been  going  on  for  an  immense  period ;  the  interior  is  ready  to 
fall  away  from  the  stiff  envelope ;  the  sinking  of  several  hundred  thou 
sand  square  miles  of  surface  takes  place.  Consequently  the  older  ridges 
are  forced  nearer  together,  and  as  they  move  towards  each  other  the 
intervening  horizontal  Atlantic  rocks  are  mercilessly  crumpled  up,  folded, 
and  broken.  As  the  force  exerted  is  irresistible,  the  two  prominent  Mt. 
Washington  and  Green  Mountain  ranges  are  crowded  up  so  as  to  become 
conspicuous  elevations.* 

*  It  is  sufficient  fur  our  present  purpose  to  refer  the  origin  of  the  Atlantic  mountains  to  a  lateral  pres 
sure  produced  in  connection  with  the  shrinkage  of  the  earth's  crust.  There  are  a  multitude  of  considera 
tions  which  ought  to  be  presented  in  order  to  elucidate  the  subject  properly.  I  propose  to  devote  an  entire 
chapter  to  the  statement  of  a  proper  theory  of  the  elevation  of  mountains,  with  abundant  historical  references', 


520  PHYSICAL  GEOGRAPHY. 

TIIK  PROCESS  OF  METAMORPIIISM. 

The  alteration  of  the  rocks  is  intimately  connected  with  the  elevation 
of  mountains  and  continents.  The  agents  which  caused  the  land  to 
bulge  upwards  also  induced  the  conditions  favorable  to  metamorphism. 
Crystalline  rocks  abound  in  regions  of  disturbance,  and  are  mostly  want 
ing  where  subterranean  influences  have  not  been  liberated  through 
dislocations  and  crumpling. 

The  problem  awaiting  solution  is  this :  How  can  the  original  hetero 
geneous  mixtures  of  clay,  sand,  and  gravel  become  arranged  into  essen 
tially  homogeneous  layers  of  crystalline  schists  of  gneiss,  Concord 
granite,  ferruginous  and  andalusite  rocks  ?  There  is  no  superficial 
resemblance  between  river  sand  and  Concord  granite ; — what  is  the 
process  by  which  the  latter  can  be  evolved  from  the  former? 

In  reply,  we  must  assume  the  identity  in  mineral  composition  between 
the  original  and  derived  masses,  save  in  these  few  cases  where  evidence 
of  the  withdrawal  of  one  and  the  substitution  of  another  ingredient  can 
be  rendered  probable.  Granting  this  point,  we  have  simply  to  show  that 
the  sedimentary  beds  have  been  subjected  to  conditions  suitable  for  the 
action  of  elective  affinities  among  the  atoms. 

If  aggregations  of  minerals  are  exposed  to  great  heat,  so  as  to  be 
reduced  to  the  melted  state,  the  conditions  would  be  favorable  for  the 
action  of  elective  affinities,  and  new  compounds  would  result.  When 
ever  this  experiment  is  tried,  the  results  agree  with  our  expectations. 
Whoever  examines  the  slag  of  a  furnace,  or  the  lava  freshly  ejected  from 
a  crater,  will  find  many  crystals  scattered  in  geodic  cavities  throughout 
the  material  that  has  been  melted.  The  elements  have  been  redistrib 
uted  into  new  compounds,  because  the  conditions  were  favorable  to  their 
transposition  and  recombination. 

But  the  heat  required  for  the  melting  of  solids  is  more  than  sufficient 
for  the  simple  metamorphism  of  strata.  It  may  be  that  certain  eruptive 
granites  have  come  from  the  absolute  melting  of  strata ;  but  the  schists 
of  the  Atlantic  gneiss  have  not  lost  their  stratification.  If  the  original 

giving  credit  to  those  who  have  made  important  suggestions  towards  the  true  explanation  of  the  process. 
This  essay  must  be  deferred  to  the  next  volume,  because  the  present  one  is  already  sufficiently  large  to  be 
conveniently  handled.  Extensive  reference  to  metamorphism  is  also  deferred  for  the  same  reason. 


PHYSICAL    HISTORY   OF    NEW    HAMPSHIRE.  521 

heterogeneous  deposits  possessed  peculiar  chemical  characters,  they  still 
remain.  There  has  been  chemical  action  in  the  midst  of  the  particles  of 
each  stratum.  The  atoms  have  been  perfectly  free  to  move  about  and 
enter  into  new  combinations.  And  it  is  easy  to  understand  what  condi 
tions  may  insure  these  results.  If  the  rocks  are  charged  with  hot  water 
or  steam,  they  will  assume  a  considerable  plasticity,  and  the  atoms  will 
be  free  to  move  in  all  directions,  perhaps  confined  by  the  walls  of  particu 
lar  strata.  Other  conditions  favor  the  chemical  reactions.  Great  pres 
sure  gives  energy  to  the  action,  and  there  is  an  abundance  of  time  allowed 
for  the  completion  of  the  work.  In  a  furnace  the  fire  is  removed,  and 
the  minerals  have  very  little  time  to  crystallize  out.  But  the  metamor- 
phic  action  may  continue  for  hundreds  or  thousands  of  years  without 
diminution.  It  is  this  long  continued  constant  agency  which  accom 
plishes  in  the  end  as  much  as  a  more  thorough  melting  in  a  short  time. 

The  conditions  favorable  for  the  metamorphism  of  rocks  are  developed 
during  periods  of  elevation.  I.  The  motion  of  shoving  along  the  strata 
is  converted  into  heat.  2.  When  this  force  has  crushed  rocks,  an 
immense  amount  of  heat  has  been  liberated,  enough  to  melt  entirely  the 
mashed  material.  3.  Elevating  forces  are  connected  with  displays  of 
subterranean  heat.  When  strata  are  broken,  immensely  large  fissures 
are  made,  which  extend  down  to  igneous  masses  below  the  crust,  not 
necessarily  a  melted  interior,  but  large  reservoirs,  comparable  with  oceans 
for  size.  Compression  may  bring  portions  of  this  igneous  material  to  the 
surface  through  the  fault,  or  at  least  send  up  strong  thermal  influences. 
All  these  combined  are  sufficient  to  produce  metamorphic  changes. 

The  facts  of  plication  and  disturbance  are  everywhere  evident  in  the 
Atlantic  rocks,  so  that,  whether  we  fully  understand  the  process  or  not, 
it  is  clear  that  the  formation  has  been  subjected  to  influences  capable  of 
rendering  them  plastic,  and  thus  of  allowing  chemical  changes. 

As  to  the  character  of  the  original  strata,  it  is  likely  that  they  were  all 
derived  from  the  older  porphyritic  strata  by  the  action  of  currents  of 
water  of  different  velocities.  The  ordinary  gneisses  correspond  with  the 
average  composition  of  the  older  rock,  and  may  have  resulted  from  their 
disintegration,  the  newer  strata  being  argillaceous  sandstones.  The 
ferruginous  rock  is  fully  four  fifths  silica,  and  its  origin  may  be  ascribed 

to  those  currents  which  were  fitted  to  transport  finely  divided  silica.     As

the  ferruginous  appearance  results  from  the  decomposition  of  iron 
pyrites,  it  is  perhaps  reasonable  to  look  to  the  waters  of  the  ocean  for 
the  small  percentage  of  sulphur  required  to  combine  with  the  iron  of  the 
mud.  This  may  have  been  reduced  from  sulphates  in  the  water  through 
the  agency  of  organic  matter.  The  andalusite  rocks  were  probably  very 
clayey,  deficient  in  alkali.  This  clay  might  result  from  the  decomposition 
of  feldspar.  As  the  removal  of  potash  and  soda  from  feldspar  is  the  pre 
requisite  for  its  disintegration,  the  resulting  clays  might  be  deficient  in 
the  alkalies.  After  metamorphism  we  should  therefore  expect  the  pro 
duction  of  schists  corresponding  in  mineral  composition,  or  with  the 
predominance  of  silicates  of  alumina  without  an  alkali,  like  andalusite, 
fibrolite,  staurolite,  and  kyanite.  These  schists  do  not  usually  contain  a 
large  proportion  of  feldspar. 

The  Concord  granite  would  probably  come  from  argillaceous  sand 
stones,  the  silica  being  rather  meagre  in  amount.  This  division  has 
probably  been  subjected  to  peculiar  influences,  so  as  to  induce  the  com 
pact,  even  structure  of  the  rock.  The  appearances  would  indicate  a  long 
continued  quiet  metamorphic  action,  which  has  reduced  the  minerals  to  a 
uniformly  fine  texture.  The  rock  is  evidently  the  equivalent  of  the 
celebrated  Monson,  Mass.,  stone,  where  the  layers  of  deposition  are  as 
evident  as  in  a  freshly  excavated  hill  of  sand.  It  would  seem  as  if  the 
action  in  the  latter  case  had  been  retarded  before  the  conversion  of  the 
material  into  so  homogeneous  a  mass. 

More  than  one  period  of  metamorphism  seems  to  be  indicated  by  the 
facts.  The  Franconia  breccia  holds  in  its  embrace  fragments  of  meta 
morphic  rocks  of  all  the  varieties  that  are  peculiar  to  the  Atlantic  sys 
tem  in  that  part  of  the  state.  The  original  formations  must  therefore 
have  all  been  altered  prior  to  the  production  of  the  breccia.  Possibly 
this  rock  belongs  to  the  following  period,  but  it  was  as  certainly  prior 
to  that,  as  it  clearly  followed  the  Atlantic  age.  Hence  I  have  regarded 
it  as  marking  the  transition  between  these  two  great  eras. 

USE  OF  THE  TERMS  ATLANTIC  AND  MoNTALBAN. 

Those  who  have  read  the  annual  reports  will  observe  that  this  is  the  first  occasion 
in  which  I  have  used  the  term  Atlantic.  My  first  report,  printed  in  1869,  proposes  the 
name  of  White  Mountain  series  for  all  the  gneissic  rocks  east  of  the  staurolite  rock  in 
Lisbon  (see  page  17  of  this  volume) .  In  1870,  Dr.  T.  Sterry  Hunt  wrote  a  letter  to  Prof. 


PHYSICAL   HISTORY   OF   NEW   HAMPSHIRE.  523 

Dana  upon  the  geology  of  eastern  New  England,  published  in  the  American  Journal 
of  Science,  II,  vol.  L,  p.  83,  in  which  he  includes  the  rocks  of  the  White  Mountains 
with  a  group  in  Nova  Scotia  recently  investigated  by  Mr.  Murray,  and  stated  to  contain 
"soft  bluish-grey  mica  slates  and  micaceous  limestones,  belonging  to  the  Potsdam 
group ;  besides  a  great  mass  of  whitish  granitoid  mica  slates,  whose  relation  to  the 
Potsdam  is  still  uncertain.  To  the  whole  of  these  we  may  perhaps  give  the  provisional 
name  of  the  Terranovan  series,  in  allusion  to  the  name  Newfoundland."  This  series 
is  definitely  stated  to  lie  "between  the  Laurentian  and  the  Quebec  group." 

Next,  Dr.  Hunt  describes  rocks  of  similar  characters  on  the  St.  Croix,  N.  B.,  and  in 
Nova  Scotia.  He  says  of  the  latter, — "  These  include  mica  schists  with  chiastolite  and 
garnet,  and  appear  identical  with  those  already  observed  by  Dr.  Dawson  in  other  parts 
of  Nova  Scotia,  which  I  had  already  recognized  as  the  same  with  those  of  the  White 
Mountains,  and  those  of  the  St.  Croix."  He  says  further  of  the  same, — "which  I 
believe  to  belong,  like  those  of  the  St.  Croix  and  the  St.  John  rivers,  to  the  great 
Terranovan  series.  The  micaceous  and  hornblendic  schists,  with  interstratified  fine 
grained  white  gneisses  (locally  known  as  granites)  which  I  have  seen  in  Hallowell, 
Augusta,  Brunswick,  and  Westbrook,  in  Maine,  appear  to  belong  to  the  same  series, 
which  will  also  probably  include  much  of  the  gneiss  and  mica  schist  of  eastern  New 
England."  Of  another  region  he  says,  in  the  same  letter, — "I  believe,  however,  that 
much  of  the  calcareous  mica  slate  of  eastern  Vermont  will  be  found  to  belong  to  the 
Terranovan  series." 

From  these  quotations  I  think  it  plain  that  the  author  is  inclined  to  believe  that  the 
rocks  of  the  White  Mountains,  together  with  the  micaceous  staurolitic  rocks  of  eastern 
Vermont,  belong  to  one  system,  which  is  styled  the  Terranovan.  As  certainly  a  part 
of  this  is  stated  to  belong  to  the  Potsdam,  I  should  infer  that  the  author  believed  the 
Terranovan  series  to  have  been  deposited  about  the  time  of  the  Potsdam  or  Cambrian 
period. 

In  1870,  my  second  annual  report  (page  26  of  this  volume)  amplifies  the  definition 
of  the  White  Mountain  series,  making  it  to  include  everything  now  referred  to  the 
Atlantic  system,  and,  also,  the  porphyritic  granite.  The  name  of  Coos  group  was 
applied  in  the  second  report  to  a  set  of  rocks  along  Connecticut  river,  that  had  been 
marked  in  1869,  upon  a  published  map,  as  distinct  from  the  White  Mountain  series. 
This  report  was  prepared  immediately  after  the  reading  of  Dr.  Hunt's  letter,  referred 
to  above,  in  manuscript;  and  the  two  documents  were  printed  about  the  same  time.  I 
gave  the  name  under  the  impression  that  the  group  represented  by  it  corresponded 
to  the  Terranovan  series  of  Newfoundland,  and  was  nearly  of  Cambrian  age ;  but,  as 
distinctly  shown  in  the  reports  for  1869  and  1870,  I  separated  the  Coos  from  the  White 
Mountain  series,  the  latter  being  regarded  as  pre-Cambrian. 

In  1871,  Dr.  Hunt  delivered  a  very  able  and  carefully  prepared  address  before  the 
American  Association  for  the  Advancement  of  Science,  in  which  he  distinguished 
between  the  gneiss  of  the  Adirondacks,  the  quartzo-feldspathic  rocks  of  central  Ver 
mont  (improperly  termed  the  "Green  Mountain  series,"  since  the  rocks  of  the  Green 


524  PHYSICAL    GEOGRAPHY. 

Mountain  axis,  both  in  Vermont  and  for  a  considerable  distance  into  Canada,  are  the 
same  with  the  White  Mountain  series),  and  the  White  Mountain  series.  This  address 
seems  to  be  the  first  place  where  the  author  uses  the  term  White  Mountain  series  to 
apply  to  a  system  of  rocks,  and  he  evidently  intends  that  it  shall  take  the  place  of  the 
name  of  Terranovan  (p.  33).  Dr.  Hunt,  in  this  address,  clearly  states  that  he  believes 
this  series  of  rocks  to  be  both  pre-Silurian  and  pre-Cambrian  in  age  ;  and  I  owe  him 
an  apology  for  quoting  him,  on  one  occasion,  as  having  called  them  Cambrian  in  this 
address.  My  only  excuse  is  the  impression  derived  from  his  letter  of  the  previous 
year,  that  he  considered  the  White  Mountain  series  the  equivalent  of  the  rocks  in 
Newfoundland  carrying  Potsdam  fossils,  and  my  inability  to  be  present  during  the 
delivery  of  the  Indianapolis  address. 

It  will  be  observed  that  the  definition  of  White  Mountain  series,  given  in  this  ad 
dress,  corresponds  with  mine  of  the  previous  year,  even  to  including  the  porphyritic 
gneiss,  as  respects  the  older  strata,  but  differs  by  including  the  equivalents  of  the  Coos 
group  with  the  older  series.  Subsequently  Dr.  Hunt  suggested  the  use  of  the  adjective 
Montalban  instead  of  White  Mountain. 

I  have  presented  these  statements  for  two  reasons, — first,  to  correct  a  misapprehen 
sion  of  Dr.  Hunt,  stated  in  public  on  two  occasions,  in  reference  to  the  question  who 
first  assigned  the  White  Mountain  rocks  to  their  proper  place  beneath  the  Cambrian ; 
and,  second,  to  justify  myself,  as  the  originator  of  the  term  White  Mountain  series,  in 
restricting  its  application,  and  returning  to  an  older  name  for  the  large  division,  first 
suggested  in  1835. 

In  the  Proceedings  of  the  American  Association  for  the  Advancement  of  Science,  vol. 
xxii,  p.  116,  after  expiessing  the  opinion  that  the  White  Mountain  rocks  are  pre-Cam 
brian  in  age,  Dr.  Hunt  says,  "this  view  is,  I  believe,  adopted  by  Prof.  Hitchcock." 
A  similar  expression  is  made  use  of  in  the  Proceedings  of  tiie  Boston  Society  of  Natural 
History,  vol.  xv,  p.  310.  It  would  appear,  however,  from  the  historical  statements 
given  above,  that  Dr.  Hunt,  rather  than  the  author,  has  "adopted"  this  view.  It  is 
to  be  presumed  that  both  of  us  arrived  at  the  same  conclusion  independently  of 
each  other ;  while  it  is  to  the  credit  of  the  New  Hampshire  geologist  that  his  official 
report  contained  the  first  announcement  of  the  use  of  a  term  derived  from  the  geog 
raphy  of  his  field  of  labor.  That  this  new  use  of  the  name  White  Mountains  should 
be  employed  by  so  able  an  investigator  as  Dr.  Hunt,  only  two  years  after  its  sugges 
tion  in  the  state  report,  is  confirmatory  evidence  of  the  appropriateness  of  the  desig 
nation. 

In  1812  and  1817,  William  Maclure  published  geological  maps  of  the  United  States, 
on  which  is  represented  an  area  of  "primitive  rocks"  extending  from  Maine  to 
Alabama,  and  including  the  Adirondack  region.  From  the  accompanying  text  it  ap 
pears  that  these  rocks  are  regarded  as  a  formation,  and  as  the  oldest  known  in  the 
country. 

In  !835,  G.  W.  Featherstonhaugh,  in  a  report  upon  the  "Elevated  Country  between 
Missouri  and  Red  Rivers,"  urged  the  necessity  of  giving  a  general  name  to  the  chain 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  525 

of  mountains,  as  well  as  to  the  formation  holding  them,  occupying  the  region  of  the 
primitive  rocks  of  Maclure.  The  mountains  specified  are  the  Blue  Ridge,  Alleghany 
mountain,  Iron  mountain,  Unaka,  etc.,  and  the  name  proposed  is  that  of  Atlantic 
Primary  Chain*  From  further  remarks  by  Mr.  Featherstonhaugh,  1836,  in  his  report 
of  a  geological  reconnoissance  by  way  of  "  Green  Bay  and  the  Wisconsin  Territory  to 
Coteau  de  Prairie,"  it  appears  that  he  intended  to  have  the  name  Atlantic  applied  to 
these  primary  rocks  in  the  same  sense  that  Cambrian  and  Silurian  were  applied  to 
formations  in  England  by  Sedgwick  and  Murchison.  He  says,  p.  38, — "the  terms 
primary  and  primordial  are,  undoubtedly,  always  very  properly  applied  to  the  lower 
rocks,  to  which  an  igneous  origin  has  been  attributed  ;  but  may  fairly  be  extended  to 
any  series  of  rocks  constituting  a  great  geographical  boundary,  to  which  they  give  a 
predominating  character,  especially  at  a  period  when  the  term  transition  is  passing  into 
disuse,  and  leaves  the  term  primary  freed  from  theoretical  views,  to  class  all  the  rocks 
in  below  the  secondary  order."  In  his  "  secondary,"  he  expressly  includes  the  Cam 
brian  of  Sedgwick,  so  that  his  application  of  the  term  Atlantic  is  free  from  ambiguity. 
It  includes  the  geographical  area  of  crystalline  rocks  from  Maine  to  Alabama,  which 
are  supposed  to  be  pre-Cambrian.  This  proposition  was  objected  to  by  Prof.  W.  B. 
Rogers,  state  geologist  of  Virginia,  in  his  Geological  Reconnoissance,  published  in 
1836,  on  the  ground  of  "superficial  and  precipitate  generalization."  It  was  at  this 
time  that  Messrs.  H.  D.  and  W.  B.  Rogers,  and  other  eminent  geologists,  began  to 
entertain  the  notion  that  the  New  England  portion  of  the  Atlantic  crystalline  area 
consisted  of  metamorphic  paleozoic  strata.  If  this  were  a  theory,  confirmed  by 
explorations,  then  the  adoption  of  Featherstonhaugh's  suggestion  would  have  led 
the  world  astray.  Inasmuch  as  the  metamorphic  theory  blinded  the  eyes  of  geol 
ogists  for  thirty  years,  the  proposed  use  of  the  word  Atlantic  was  lost  sight  of; 
and  those  of  us  who  now  find  that  the  older  theories  best  explain  the  phenomena 
discovered  by  exploration  had  forgotten  Featherstonhaugh's  proposal,  and  had 
made  use  of  the  term  White  Mountain  series  in  its  place.  But  now,  finding  that 
the  proposal  proves  to  be  correct,  we  cannot  do  better  than  accept  it,  to  the 
exclusion  of  the  term  Montalban,  for  application  to  the  entire  system.  Meanwhile, 
the  necessity  for  the  use  of  a  geographical  term  for  the  oldest  rocks  led  Sir 
W.  E.  Logan  to  apply  the  terms  Laurentian  and  Huronian  to  the  primitive  formations 
in.Canada,  expressly  to  the  exclusion  of  the  Atlantic  rocks,  as  this  author  believed,  in 
the  Paleozoic  age  of  the  New  England  crystalline  schists ;  and  these  terms  have  been 
generally  adopted.  Featherstonhaugh  did  not  know  that  the  "primary"  group  was 
susceptible  of  subdivisions ;  but  the  study  of  the  eastern  belt  of  crystalline  schists  by 
Dr.  Hunt  led  him,  in  his  address  at  Indianapolis,  to  refer  them  to  the  White  Mountain 

*  The  original  proposition  is  couched  in  the  following  language :  "  It  will  be  apparent,  I  think,  to  every 
geologist,  that  as  this  primary  chain  is  the  true  boundary  of  the  sedimentary  rocks  lying  west  of  it,  and  forms  so 
important  a  feature  in  the  mineral  structure  of  the  country,  it  should  receive  a  clear  geological  designation  ;  and 
as  it  looks  upon  the  Atlantic  coast  in  its  whole  course,  I  shall  propose  the  name  of  the  ATLANTIC  PKIMARY 
CHAIN."  Featherstonhaugh' s  Report,  1835,  p.  33,  second  edition, — as  the  one  printed  with  the  reports  of 
congress  does  not  contain  this  paragraph. 


526  PHYSICAL    GEOGRAPHY. 

series,*  a  group  of  rocks  intermediate  between  the  Laurentian  and  Cambrian,  and 
exclusive  of  the  Huronian.  This  proposal  will  relieve  a  multitude  of  difficulties,  and 
enables  us  to  place  the  Atlantic  system  midway  between  the  most  ancient  Laurentian 
and  the  Paleozoic,  so  that  both  parties  in  the  metamorphic  controversy  may  be  pleased 
because  their  opponents  are  not  altogether  in  the  right.  Furthermore,  the  express 
exclusion  of  the  New  England  rocks  from  the  Laurentian,  and  the  omission  of  all 
reference  to  the  true  Laurentian  areas  by  Featherstonhaugh  in  his  definition  of  Atlantic, 
enables  us,  both  by  a  true  regard  for  historical  accuracy  and  correct  geological  discrim 
ination,  properly  to  apply  the  latter  term  to  the  eastern  belt  of  crystalline  strata,  from 
New  Brunswick,  through  New  England,  south-eastern  New  York,  etc.,  east  of  the 
great  valley  of  Virginia  to  Alabama. 

There  is  a  modification  of  the  term  Montalban  now  requiring  specification.  The 
White  Mountains  contain  of  this  system  only  the  tender  friable  gneisses  described 
by  Dr.  Hunt,  with  the  layers  carrying  andalusite  and  the  Concord  granite.  Our 
researches  show  that  the  rocks  of  this  geographical  area  properly  constitute  a  separate 
division  of  the  whole  gneissic  series  of  New  Hampshire,  and  therefore  Montalban  may 
naturally  be  restricted  to  express  these  and  no  others.  The  present  chapter  indicates 
other  modifications  also.  First,  the  porphyritic  gneiss  is  older  than  any  other  of  the 
gneisses,  and  may  for  the  present  be  removed  from  the  Atlantic  system,  partly  because 
it  may  be  represented  in  the  true  Laurentian,  and  partly  because,  in  generalizations 
respecting  the  growth  of  the  North  American  continent,  the  Atlantic  border  rocks  seem 
to  have  had  a  later  origin.  Explorers  in  the  Laurentian  fields  will  do  a  great  service 
by  ascertaining  whether  the  porphyritic  rocks  cannot  be  separated  stratigraphically 
from  the  firm  massive  pyroxenic  gneisses,  which  are  so  distinct  from  the  tender  schists 
of  the  east.  The  porphyritic  gneiss  has  been  included  in  the  Atlantic  and  Montalban 
series  by  all  writers  in  publications  previous  to  the  present.  It  is  said  to  be  a  very 
conspicuous  formation  in  North  Carolina,  where  it  is  regarded  by  Prof.  Kerr  as  the 
oldest  of  the  crystalline  series.  Second,  in  New  Hampshire  the  Bethlehem,  Lake, 
and  Franconia  series  seem  to  be  independent  formations,  separable  readily  for  strati- 
graphical  reasons  from  each  other,  and  from  the  Montalban.  The  second  distinction 
was  first  drawn  by  us  in  1873,  at  the  Portland  meeting  of  the  Association  for  the 
Advancement  of  Science.  See  vol.  xxii,  p.  123.  I  am  disposed  now  to  group  all 
these  older  strata  as  follows  :

*  In  what  I  have  said  concerning  the  priority  of  suggestion  in  respect  to  the  White  Mountain  series,  I  desire  it 
to  be  distinctly  understood  that  to  Dr.  Hunt  is  due  the  credit  of  first  assigning  these  rocks  to  a  new  system  of 
different  age  from  any  described  formation,  though  he  has  unfortunately  included  some  later  rocks  with  them.  I 


PHYSICAL  HISTORY  OF  NEW  HAMPSHIRE.  527 

THE  LABRADOR  PERIOD. 

Let  us  now  consider  the  main  topographical  features  of  the  area  above 
water  at  the  commencement  of  the  Labrador  Period.  From  some  un 
known  spot  in  Maine,  the  country  rises  to  the  Mt.  Washington  range  in 
New  Hampshire.  These  peaks  probably  did  not  rise  so  high  as  at  pres 
ent  above  the  water.  The  range  continued  southerly  through  New 
England,  spreading  out  broadly  about  the  Winnipiseogee  region.  West 
ward  the  fundamental  ridge  of  the  Green  Mountains  stretches  its  length 
along,  passing  southerly  to  form  the  New  York  and  New  Jersey  high 
lands.  Between  the  White  and  Green  ranges  lies  the  long,  shallow 
island  from  Essex  county,  Vt,  to  Massachusetts,  on  the  west  side  of 
the  present  Connecticut  valley.  The  land  on  the  two  sides  of  the  Con 
necticut  nearly  unites  along  the  north  Massachusetts  line,  while  the 
ocean  broadens  and  deepens  northerly  towards  Canada. 

In  consequence  of  the  strain  exerted  upon  the  infant  continent  by 
lateral  pressure,  there  may  have  been  a  break  in  the  strata  along  the 
upper  Saco  valley,  say  above  Sawyer's  river.  The  result  would  be  the 
upthrow  of  the  White  Mountains  from  Mt.  Webster  to  Mt.  Madison,  and 
the  settling  down  of  a  considerable  tract  of  land  to  the  west  of  the 
Saco.  There  would  result,  therefore,  a  depression  or  hydrographic 
basin  over  a  part  of  the  White  Mountain  area,  with  these  limits : 
bounded  easterly  by  the  Washington  range,  the  Carter  mountains  and 
their  foot-hills  in  Bean's  Purchase,  Jackson,  and  almost  by  the  Maine 
line ;  southerly,  by  the  foundation  ridge  of  the  Chocorua  range  between 
Conway  and  Black  mountain  in  Sandwich ;  westerly,  by  the  Moosilauke- 
Kinsman  range;  northerly,  by  the  gneiss  in  Bethlehem  and  Cherry 
mountain  in  Carroll.  Corresponding  depressions,  not  necessarily  pro 
duced  by  a  sinking  of  the  land,  appear  in  Kilkenny,  Stark,  Columbia, 

claimed  the  merit  of  having  previously  recognized  the  rocks  as  older  than  the  Silurian,  but  had  not  in  mind  any 
definite  place  for  them.  I  remember  my  father,  in  conversation,  once  expressed  to  me  his  conviction  that  the 
New  England  rocks  would  prove  to  belong  to  a  system  distinct  from  anything  then  known,  and  of  about  the  age 
of  the  Cambrian;  and  I  also  recollect  expressing  emphatically  a  similar  opinion  at  the  Chicago  meeting  of  the 
American  Association  for  the  Advancement  of  Science  in  1868;  but  these  surmises  were  not  developed  into 
reasonable  theories  by  hard  study.  Neither  of  us  could  claim  the  credit  of  first  describing  this  system  in  the 
full  sense  of  the  term,  any  more  than  my  father  could  claim  the  invention  of  the  telegraph;  for,  in  a  popular 
lecture  upon  galvanism,  delivered  at  Newburyport,  Mass.,  some  years  before  Prof.  Morse's  discoveries,  he 
declared  his  belief  that,  by  means  of  galvanic  electricity,  people  would  ere  long  be  able  to  communicate  with 
each  other  instantaneously  at  stations  many  miles  apart.  These  surmises  were  all  creditable,  but  did  not  lead 
to  the  actual  discoveries.

Essex  county,  Vt,  and  elsewhere,  as  shown  upon  the  third  of  our  map 
illustrations.  The  Pemigewasset  basin  was  the  largest  of  any  of  them. 
Such  a  terrible  earthquake  as  must  have  accompanied  the  sinking  of  this 
land  could  not  very  well  have  passed  away  without  leaving  behind  a 
copious  outflow  of  igneous  matter.  Immediately  subsequent  to  the  cat 
aclysm,  we  find  indubitable  evidence  of  the  largest  eruption  ever  known 
in  New  Hampshire.  This  Pemigewasset  area  was  speedily  overspread 
by  a  mass  of  liquid  granite,  oozing  out  from  the  rent  in  the  gneiss,  reach 
ing  down  to  the  igneous  reservoir.  From  the  Crawford  house  to  Mt. 
Lafayette,  and  from  the  White  Mountain  house  to  Mt.  Whiteface,  and 
from  Franconia  to  Conway,  the  country  was  flooded.  Were  there  ships 
of  steel  they  might  have  floated  on  this  liquid  lake,  for  the  surface  was 
as  level  as  the  ocean. 

Possibly  the  outlet  of  the  fiery  flood  lay  along  the  Saco  valley  in  the 
line  of  disturbance.  That  this  flood  is  not  a  myth,  I  would  point  to  its 
localities,  and  claim  that  its  surface  is  well  marked  to-day.  Remove  the 
overlying  rock,  and  the  top  of  the  granite  will  appear  as  flat  as  a  western 
prairie.  The  igneous  material  I  call  the  granite  of  Conway,  since  the  most 
of  this  town  is  underlaid  by  it.  It  appears  also  from  the  Flume  to  the 
Basin  in  Franconia,  constituting  much  of  Mts.  Profile,  Osceola,  Fisher, 
and  a  host  of  peaks  in  the  unexplored  Pemigewasset  area.  The  Notch 
has  been  excavated  out  of  it,  also  the  valleys  of  the  Saco,  Swift,  and  Mad 
rivers  and  their  tributaries.  It  is  not  entire,  as  when  formed,  since  the 
tooth  of  time  has  gnawed  into  it,  or  eaten  through  in  a  few  instances. 
Very  soon  the  uneasy  earth  vomited  out  another  igneous  flood,  covering 
the  same  area,  and  nearly  as  great  a  quantity.  Modern  volcanoes  are 
apt  to  throw  out  lava  of  slightly  different  mineral  character  at  succes 
sive  epochs  of  eruption.  So  it  was  with  these  ancient  New  Hampshire 
vents.  The  second  overflow  is  a  granite,  spotted  with  rounded  crystals 
of  feldspar,  and  scarcely  any  quartz  is  present.  The  first  carried  a  con 
siderable  quartz.  The  second  verges  into  a  compact  feldspathic  mass. 
I  call  it  the  Albany  granite.  If  you  desire  to  see  localities,  visit  Welch 
mountain,  Mts.  Flume  and  Liberty  in  Franconia,  the  summit  of  Profile, 
the  Twin  mountains,  and  certain  peaks  in  Bartlett  and  Jackson,  besides 
many  elevations  in  Albany.  This  material  thins  out  in  the  east.  Be 
neath  Pequawket  it  is  not  over  one  hundred  feet  thick,  while  it  is  eight

hundred  or  one  thousand  feet  elsewhere,  as  in  the  Twins,  and  Mts.  Flume 
and  Liberty.  It  crops  out  also  near  the  summit  of  Lafayette.  A  third 
outburst  was  more  limited,  but  it  gave  rise  to  the  sharp  peak  of  Cho- 
corua  and  to  small  hills  west  of  Mt.  Hancock,  which  I  term  the  Chocorua 
granite.  It  is  likely  that  corresponding  eruptions  gave  rise  to  similar 
granites  in  the  Starr  King  group  of  mountains,  Stratford  and  Columbia, 
the  granitic  country  of  Essex  county,  the  gores  of  wild  land  east  of 
Montpelier,  Little  Ascutney,  and  about  Cuttingsville,  Vt,  besides  the 
Ossipee  mountains  east  of  Winnipiseogee.  Possibly  the  latter  may  have 
accumulated  by  a  branch  stream  running  southerly  from  the  Saco  river 
outburst.  This  granite,  when  finally  cooled  off,  seems  to  have  been 
covered  by  water,  since  there  succeeds  a  great  thickness  of  fine  sedi 
mentary  deposits.  This  proves  to  be  of  four  kinds, — coarse  and  fine 
labradorites  and  variously  colored  potash  feldspars  above  the  first.  We 
suppose  these  must  have  covered  the  granites,  or  nearly  so.  When  this 
basin  was  full,  there  would  be  a  level  country  from  Lafayette  across  to 
Mt.  Tom,  just  back  of  the  Crawford  house. 

It  seems  strange  that  the  topographical  aspect  of  a  portion  of  the 
White  Mountains  more  nearly  resembles  the  eroded  Carboniferous  pla 
teau  of  West  Virginia  than  any  other  district.  The  character  of  these 
mountains  may  be  predicted  in  advance  of  examination,  since  there  is  so 
general  a  correspondence  between  altitude  and  lithological  structure.  If 
a  five-thousand-feet  mountain  shows  the  Conway  granite  at  its  base,  fel- 
sites  may  be  looked  for  at  its  summit.  Pemigewasset  has  in  it  three 
mountain  ranges  running  southerly, — Lafayette  on  the  west,  and  Mt. 
Tom  on  the  east ;  both  these  and  the  central  Twin  mountains  show  the 
whole  series  from  the  low  granite  to  the  upper  felsites,  while  the  inter 
vening  ranges  have  been  removed  by  erosion  down  to  the  lowest  granite, 
the  formations  reposing  horizontally.  This  is  like  the  narrow  valleys  in 
West  Virginia,  cut  through  by  the  Kanawha  and  Guyandotte  rivers  and 
their  tributaries.  The  map  shows  a  smaller  Labrador  area  resting  upon 
the  Green  Mountain  range  near  Cuttingsville  on  the  Rutland  &  Burling 
ton  Railroad,  and  not  a  great  distance  from  Rutland.  This  area  is  com 
posed  apparently  of  the  Chocorua  granite,  resting  upon  Montalban  gneiss. 
It  is  an  interesting  locality,  because  it  shows  the  similarity  between  the 
formation  of  the  White  and  Green  mountains.  The  succession  of  the

granites  and  felsites  in  the  former  is  satisfactorily  worked  out.  The 
Chocorua  rock  is  essentially  a  crystalline  labradorite.  Now  this  is  a 
mineral  usually  regarded  as  very  ancient.  Whatever  it  overlies  must 
therefore  be  older.  Hence  the  Montalban  rocks  are  more  ancient  than 
the  Chocorua  granite  in  New  Hampshire ;  and,  as  we  find  the  same 
formations  near  Rutland,  and  grouped  in  the  same  way,  it  is  fair  to  infer 
that  they  belong  to  the  same  series  as  those  in  New  Hampshire.  There 
fore  we  have  a  new  argument  for  the  Eozoic  age  of  the  Green  Mountain 
range.  I  wait  only  for  the  results  of  certain  chemical  analyses  to  publish 
the  details  of  this  discovery,  and  its  bearing  upon  the  age  of  the  Ver 
mont  formations.

Several  of  the  Labrador  areas  upon  the  map  represent  an  important 
eruption  of  sienite  after  the  deposition  of  all  the  members  which  have 
now  been  specified.  Such  arc  the  elliptical  area  in  Moultonborough 
and  Sandwich,  or  Red  hill;  part  of  the  Waterville  patch,  consisting  of 
Mt.  Tripyramid ;  the  long  strip  from  Dover  to  Salem  ;  the  northern  end 
of  the  large  expanse  of  this  rock  in  Massachusetts;  Mt.  Monadnock, 
opposite  Colebrook,  etc.  Up  Norway  brook  in  Waterville  this  rock  has 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  531 

very  plainly  oozed  through  crevices  in  the  ossipyte.  Evidence  of  intru 
sion  at  this  period  is  not  yet  obtained  from  any  other  locality ;  but,  as  the 
lithological  character  of  all  the  previously  erupted  members  is  constant, 
it  is  probable  that  these  sienites  were  all  produced  simultaneously,  most 
likely  at  the  close  of  the  Labrador  period.  Thus  this  age  of  the  world 
in  New  Hampshire  possessed  a  fiery  character.  It  was  ushered  into 
being  by  an  overflow  of  igneous  material,  nourished  with  ejections  of 
molten  rock,  and  terminated  by  upheavals,  rending  of  the  strata,  and 
pouring  of  fiery  sienite  into  the  crevices,  which  oozed  out  and  formed 
mountains. 

The  Labrador  formation  was  separated  formally  from  the  Laurentian 
by  Sir  W.  E.  Logan,  in  1865.  It  is  developed  quite  differently  in  Canada 
from  its  usual  aspect  in  the  White  Mountains.  Logan  estimates  the 
thickness  of  the  anorthosite  gneisses  of  this  system  at  thirteen  thousand 
feet.  They  are  inter-stratified  with  orthoclase  gneiss,  quartz,  and  lime 
stones.  I  do  not  find,  from  the  descriptions,  that  there  is  any  great 
difference  in  the  angle  of  the  dip  between  the  Labrador  and  Laurentian. 

But  there  is  a  closer  resemblance  between  the  New  Hampshire  and 
the  Canadian  Labrador  rocks,  on  the  north  shore  of  the  St.  Lawrence 
beyond  the  Saguenay  river,  according  to  James  Richardson.  He  says 
the  Laurentian  gneiss  is  nearly  vertical,  with  a  north-south  strike,  and 
much  broken,  while  the  Labrador  rocks  dip  at  comparatively  moderate 
angles,  strike  nearly  east  and  west,  and  are  free  from  contortions  and 
disturbances.*  In  the  Adirondacks,  the  descriptions  of  Prof.  Emmons 
would  indicate  that  the  labradorite  rocks  occupy  the  centre  and  highest 
part  of  the  Eozoic  area,  and,  on  this  account,  they  bear  some  resem 
blance  to  the  Pemigewasset  exposures. 

I  think  geologists  will  find  my  descriptions  of  the  New  Hampshire 
Labrador  rocks  different  from  anything  that  has  ever  been  published. 
I  cannot  find  any  author  pointing  out  areas  whose  molten  granites  have 
been  spread  out  like  lava  over  a  considerable  tract  of  country,  nor  a  defi 
nite  succession  of  granitic  overflows  characterized  by  different  mineral 
composition.  The  brief  itinerary  of  Mr.  Richardson  affords  a  hope  that 
the  bleak,  northern  shores  of  the  lower  St.  Lawrence  will  confirm  our 
views  of  the  structure  of  the  Labrador  formation,  when  they  have  been

carefully  explored.  Meanwhile  I  would  bespeak  the  attention  of  my 
brethren  of  the  hammer  to  the  brief  statement  of  my  theory  in  this 
chapter,  to  be  followed  by  fuller  technical  descriptions  in  the  next  vol 
ume.  If  confirmed  by  further  research,  these  studies  will  throw  much 
light  upon  the  origin  of  granite,  and  may  indicate  the  existence  of  the 
Labrador  system  in  many  localities  where  nothing  of  the  kind  is  now 
suspected. 

THE  HURONIAN  AGE. 

As  far  back  as  1822  my  father  distinguished  this  formation  in  Massa 
chusetts  from  all  the  other  crystalline  schists  by  the  names  of  talcose 
and  chlorite  slate.*  Essentially  the  same  delineation  has  since  appeared 
on  all  the  geological  maps  of  Massachusetts.  The  Vermont  geological 
map  shows  its  continuation  through  that  state.  In  1857,  Prof.  H.  D. 
Rogers  proposed  to  distinguish  this  formation  farther  south,  in  Penn 
sylvania  and  Maryland,  by  the  name  of  Azoic,  separating  it  from  the 
underlying  Hyposoic  gneisses.  He  regarded  the  group  as  older  than 
his  "Primal  series."  In  1858,!  I  understood  him  to  express  his  belief  in 
the  equivalency  of  the  Azoic  with  the  formation  called  Azoic  system  by 
Foster  and  Whitney  in  Michigan  (1850),  as  separated  from  their  "igneous 
granite,"  and  with  the  Huronian  system  of  Logan,  described  in  1855. 
Singularly  enough,  while  Prof.  Rogers  perceived  the  true  position  of  the 
Pennsylvania  rocks,  he  believed  the  New  England  talcose  series  to  be 
metamorphic  Paleozoic.  James  Macfarlane  seems  to  have  been  the  first 
to  express  the  opinion  that  the  Canadian  and  New  England  area  was  of 
Huronian  age.  In  this  opinion  he  was  speedily  followed  by  Prof.  Her 
mann  Credner  in  1869,  and  by  Dr.  T.  Sterry  Hunt  in  1871.  In  my  first 
annual  report  I  accepted  Logan's  interpretation  of  these  rocks,  calling 
them  altered  Quebec,  and  belonging  to  the  Lower  Silurian,  but  since 
1871  have  thought  it  better  to  refer  them  to  the  Huronian. 

The  Huronian  rocks,  as  seen  by  the  fourth  of  our  maps,  have  not 
played  a  very  important  part  in  our  history,  judging  from  the  small  areas 
now  occupied  by  them.  But  the  amount  of  time  occupied  in  their  depo 
sition,  alteration,  and  elevation  much  exceeded  the  length  of  the  previous 
eon.

PHYSICAL   HISTORY   OF   NEW   HAMPSHIRE.  533 

We  find  peculiarities  in  the  arrangement  of  land  and  water  in  this  age 
not  before  exhibited.  All  the  porphyritic  and  Atlantic  rocks  have  be 
come  solid  terra  firma,  possibly  covered  by  a  scanty  cryptogamous  vege 
tation,  sufficiently  green  to  redeem  the  state  from  sterility.  This  land  is 
mostly  along  a  central  line  in  the  state,  passing  transversely  through 
New  Hampshire  to  Massachusetts,  with  an  ocean  upon  each  side. 
That  upon  the  south-east  has  left  no  visible  traces  of  its  existence  in 
our  state,  but  deposited  much  sediment  over  Casco  bay  in  Maine.  The 
land  probably  extended  beyond  the  Isles  of  Shoals,  so  that  the  deposits 
of  this  age  are  now  concealed  by  water.  On  the  west  and  north-west 
side  the  ocean  extended  up  the  Connecticut  valley  to  Groveton,  and 
thence,  by  way  of  the  upper  Ammonoosuc  branch,  to  Umbagog  lake, 
possibly  connecting  around  the  north  side  of  the  Stratford-Odell  Lab 
rador  granites  with  a  broad  expanse  northerly,  much  wider  than  below 
and  practically  without  limit,  towards  the  Gulf  of  St.  Lawrence.  It  is 
uncertain  whether  the  Connecticut  valley  ocean  connected  with  the 
greater  body  of  water  washing  the  east  flank  of  the  Green  Mountains. 
The  Montalban  ridge,  between  Waterford  and  Reading,  Vt.,  may  have 
been  of  sufficient  elevation  to  separate  them.  If  so,  the  next  point  of 
connection  on  the  south  was  in  Connecticut. 

The  deposits  formed  in  this  period  indicate  quietness  in  the  waters. 
They  are  not  now  visible  south  of  Bellows  Falls  in  the  eastern  arm,  and 
are  not  certainly  connected  between  Berlin  and  Columbia.  They  are 
two  or  three  thousand  feet  in  thickness. 

A  marked  feature  in  this  ocean  appears  in  its  metalliferous  character, 
since  pure  gold,  and  the  sulphurets  of  iron,  copper,  and  lead,  separated 
themselves  from  it.  Gold  is  soluble  slightly  in  ferric  solutions;  and 
hence  we  may  infer  the  presence  of  per-salts  of  iron  in  the  water,  which 
leached  out  from  the  sandy  bottom  infinitesimal  particles  of  gold  existing 
as  impurities.  It  was  a  process  of  concentration,  and  agrees  with  our 
inspection  of  the  rocks  now, — for  the  talcose  rocks  carry  more  gold  than 
the  gneissic, — and  subsequently  it  accumulated  still  more  abundantly. 
Supposing  that  ferric  sulphates  containing  gold  in  solution  abound  in  the 
Huronian  ocean,  it  is  easy  to  understand  how  the  metal  should  be  pre 
cipitated  in  the  pure  state.  Some  deoxidizing  agent  acts  upon  the  ferric 
sulphate,  and  reduces  it  to  the  ferrous  condition,  and  at  the  same  time 


534  PHYSICAL   GEOGRAPHY. 

the  sulphate  is  reduced  to  a  sulphuret  Gold  is  not  known  in  nature  as  a 
sulphuret,  though  commonly  diffused  through  pyrites ;  hence  it  is  pre 
sumed  that  the  precious  metal  was  precipitated  simultaneously  with  the 
deoxidation  of  the  sulphates,  not  passing  through  the  intermediate  con 
dition  of  a  sulphuret  The  deoxidizing  agent  was  probably  vegetation. 

The  accumulation  of  the  large  beds  of  iron  and  copper  pyrites  in 
Gardner's  mountain  was  brought  about  at  the  same  time,  and  under 
similar  conditions.  For  the  formation  of  sulphurets  we  require  origi 
nally  a  sulphate  ocean,  just  as  in  the  case  of  gold.  The  deoxidizing 
action  of  vegetation  will  reduce  the  sulphates  to  sulphurets;  and  thus 
deposits  of  pyrites  of  enormous  extent  may  be  produced,  provided  there 
is  a  sufficient  store  of  the  iron  and  sulphur.  In  natural  waters,  contain 
ing  sulphates  of  lime  and  magnesia,  the  process  of  sulphate  reduction 
in  the  presence  of  decaying  plants  may  be  observed  at  the  present  day ; 
and,  if  carbonic  acid  be  present,  sulphuretted  hydrogen  gas  is  also 
evolved.  The  same  principle  is  made  use  of  in  analytical  laboratories 
for  the  separation  of  metallic  sulphurets.  A  stream  of  sulphuretted 
hydrogen  is  passed  into  metallic  solutions,  when  the  element  readily 
combines  with  the  sulphur,  producing  an  insoluble  sulphuret,  which  is 
precipitated.  The  copper  pyrites  is  so  closely  connected  with  the  iron 
that  it  has  probably  been  accumulated  in  the  same  way.  In  the  Ammo- 
noosuc  gold  region  copper  is  very  common  as  an  impurity  in  the  strata 
at  localities  remote  from  valuable  beds  of  ore;  so  that  the  sulphate 
ocean  must  have  been  highly  charged  with  the  mineral  solutions.  The 
formation  of  the  lead  sulphuret  may  be  described  in  similar  terms. 

By  referring  to  an  argument  set  forth  above  for  the  existence  of  veg 
etation,  it  will  appear  that  the  formation  of  the  iron  oxides  is  akin  to  that 
of  the  sulphurets.  Vegetation  is  the  agent  required  at  the  present  day 
for  the  production  of  both ;  hence,  by  looking  at  the  process  in  another 
way,  we  may  derive  a  different  conclusion.  The  ores  of  iron  and  copper 
require,  at  the  present  day,  the  presence  of  vegetable  matter  for  their 
formation.  These  ores  accumulated  largely  in  the  Huronian  age ;  hence 
it  is  probable  that  plants  existed  at  this  time.  No  other  evidences  of 
their  existence  have  yet  been  discovered. 

There  are  three  divisions  of  this  age : — First,  the  period  of  the  deposi 
tion  of  the  copper  and  iron  beds,  with  an  auriferous  tinge.  Second,  the 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.

formation  of  a  very  fine  siliceous  mud,  with  dolomite,  soapstone,  and 
serpentine.  More  gold  was  deposited  in  this  period  than  in  the  first. 
Third,  the  formation  of  a  small  bed  of  conglomerate  composed  of  quartz 
pebbles,  possibly  derived  from  the  rocks  of  the  first  and  second  divisions. 
Some  gold  is  present  in  this  conglomerate,  which  seems  to  be  mechani 
cally  mixed  with  the  pebbles.  This  bed  indicates  the  existence  of  a 
strong  current,  sufficient  to  carry  along  fragments  of  gold. 

The  relations  of  the  Huronian  to  the  Labrador  series  are  interesting. 
Fig.  6 1  shows  a  section  from  Northumberland  falls  to  Pilot  mountain. 
Between  Mts.  Lyon  and  Pilot  the  middle  member 
of  the  Huronian  is  disposed  in  synclinal  form,  and 
reappears  on  the  west.  The  junction  between  the  ^ 
quartzite  and  felsite  is  obscured  by  drift.  Near  by  c 
an  exposure  has  been  discovered  where  the  quart-  ? 
zite  stands  vertically,  abutting  against  the  felsite.  w 
On  breaking  off  large  masses  of  the  quartzite,  the  5 
felsite  was  seen  extending  downwards,  whence  it  ^ 
appears  evident  that  the  felsite  was  the  oldest,  un-  | 
derlying  the  slate  unconformably.  It  is  therefore 
probable  that  the  felsite  of  Mt.  Pilot  unites  with 
the  rock  of  Mt.  Lyon  underneath  the  Huronian. 

When  the   crust  of  the  earth  was  shrinking,  I 
suppose  that  the  felsite  hills  were  brought  nearer 
together  without  essentially  disturbing  their  strati-    £ 
fication.      The   rock   is    massive  and  very  tough;    £ 
while  the  slaty  Huronian  rocks  between  them  were    o 

pliable  and  easily  doubled  up  by  the  lateral  shoving    p

force.     This    conjecture  will  explain  the  seeming 

a'nomaly  of  horizontal  rocks  being  older  than  the    § 
adjacent  highly  inclined  strata. 

M 

The  Huronian  strata  are  remarkable  for  dipping    * 
at  a  very  high  angle,  almost  constantly.     The  com 
mencement  of  their  inclination  was  probably  in 
duced  at  the  close  of  this  period,  since  these  strata  arc  much   more 
highly  inclined  than  those  deposited  in  the  following  age.

THE  MICA  SCHIST  PERIODS. 

The  fifth  of  our  map  illustrations  represents  by  one  color  all  the  for 
mations  that  have  been  deposited  in  New  Hampshire  to  the  close  of  the 
Huronian;  the  other  shows  the  positions  of  the  areas  occupied  by 
several  groups  which  were  evidently  deposited  subsequently,  and  may 
belong  to  one  great  system.  They  are  thus  placed,  however,  provision 
ally.  They  are  the  Rockingham  mica  schist,  the  Merrimack  group, 
Cambrian,  auriferous  clay  slates,  and  the  Coos  group. 

The  Rockingham  schist  occupies  the  principal  portions  of  Rocking 
ham,  Strafford,  and  Belknap,  with  a  part  of  Merrimack  and  Hillsborough 
counties.  Over  this  area  it  is  generally  an  uncouth  mica  schist.  West 
of  the  Merrimack  river  there  are  several  long,  narrow  areas  of  mica 
schist  supposed  to  belong  to  the  same  group.  A  broader  range,  extend 
ing  north-easterly  from  Deering  through  Henniker  and  Hopkinton,  is 
highly  ferruginous.  A  similar  band  occupies  most  of  Weare  and  Fran- 
cestown.  A  cleaner  mica  schist  makes  up  the  substance  of  the  moun 
tain  range  extending  from  New  Ipswich  through  Sharon,  Temple,  and 
Lyndeborough.  All  these  areas  cover  Atlantic  gneisses  unconformably. 
They  lie  upon  them  like  a  blanket,  and  hinder  us  much  in  our  attempts 
to  study  the  older  formations.  The  Merrimack  group  is  a  micaceous 
quartzite  lying  adjacent  to  the  Exeter  sienite  range  on  the  north-west, 
and  has  not  yet  been  separated  from  the  previous  group.  The  occur 
rence  in  it  of  large  beds  of  soapstone,  as  at  Groton,  Mass.,  is  suggestive 
of  the  Huronian  age.  It  abounds  in  beds  of  coarse  indigenous  granite, 
which  seem  to  have  been  altered  in  situ  from  feldspathic  conglomerates. 
In  certain  parts  of  Strafford  county  these  granite  beds  predominate, 
forming  numerous  hills,  while  the  slate  occupies  the  valleys  between. 

The  schists  south-east  of  the  Exeter  sienite  range  may  belong  to  the 
same  Merrimack  era ;  but  they  are  traversed  by  several  narrow  bands  of 
clay  slate.  Possessing  a  north-west  strike,  these  slates  are  thought  to 
be  the  equivalents  of  the  Paradoxides  beds  of  Massachusetts.  It  is  obvi 
ous  that  the  physical  aspect  of  the  country  must  have  been  very  different 
from  what  it  was  in  the  Merrimack  period.  The  Merrimack  schists  must 
have  been  elevated,  then  they  were  cut  across  by  streams  flowing  south-

easterly.  Afterwards  the  land  sank,  and  these  chasms  were  filled  up 
with  mud,  which  eventually  became  converted  into  Cambrian  slates. 

Not  far  from  the  same  epoch  long  bands  of  clay  slate  were  deposited 
in  the  Connecticut  valley,  extending  from  the  Massachusetts  line  to  Coos 
county.  In  some  parts  of  this  formation  large  veins  of  auriferous  quartz 
were  formed,  whose  metallic  contents  were  derived  from  the  Huronian 
strata,  and  more  effectually  concentrated  than  before.  Many  of  the 
veins  afford  evidence  of  having  been  deposited  from  hot  water.  The 
layers  of  accretion  are  easily  distinguishable.  The  gold  may  have  been 
reduced  from  solution  by  the  same  process  as  that  recently  described. 
These  auriferous  deposits  are  of  sufficient  richness  to  be  worked  to 
advantage. 

The  Co<5s  ocean  occupied  very  much  the  same  position  as  the  Huro 
nian.  Along  the  Connecticut  valley  it  covered  the  greater  part  of 
eastern  Vermont,  in  Orleans,  Essex,  Caledonia,  and  Orange  counties. 

The  Waterford-Reading  ridge  did  not  separate  the  waters  of  the 
Connecticut  valley  from  those  just  mentioned  farther  west.  The  Ver 
mont  part  of  the  deposit  is  mostly  calcareous.  A  few  scanty  remains  of 
crinoidal  stems  have  been  taken  from  this  rock  in  Derby,  Vt,  showing 
that  life  existed.  Bordering  Connecticut  river  in  New  Hampshire,  from 
Haverhill  to  Hinsdale,  the  Coos  rocks  are  composed  chiefly  of  quartzite, 
mica  schist,  and  slates  full  of  crystals  of  staurolite  and  garnet.  This 
deposit  therefore  consisted  originally  of  clays  of  various  composition. 
Overlying  the  Atlantic  gneisses,  between  Landaff  and  Keene,  is  an 
extensive  deposit  of  andalusite  mica  schist,  including  Mts.  Carr  and 
Moosilauke.  Mt.  Monadnock  is  an  isolated  mass  of  the  same  rock,  as 
is  also  the  Kearsarge-Ragged  area.  These  schists  have  but  recently 
been  distinguished  from  the  adjacent  rocks,  and  may  be  the  equivalents 
of  the  Coos  group.  If  formed  at  the  same  time,  the  depositing  ocean 
may  have  been  separated  from  the  Connecticut  valley  by  an  Atlantic 
ridge.  The  strata  correspond  in  thickness  very  well  with  that  of  the 
staurolite  rocks. 

The  Connecticut  Coos  period  can  easily  be  divided  into  three  parts, — 
first,  the  epoch  of  the  deposition  of  mountain  masses  of  silica;  second, 
of  hornblende  and  mica  schists ;  third,  of  limestone.

Vershire,  Vt,  and  those  described  in  Hanover,  Lebanon,  etc.,  prove 
that  a  more  concentrated  sulphate  ocean  existed  in  this  than  in  the 
Huronian  period. 

In  the  White  Mountain  region  there  are  several  small  areas  of  andalu- 
site  slate,  supposed  to  be  the  equivalent  of  the  Coos  group.  They  occur 
upon  the  east  side  of  Mt.  Washington,  Mts.  Willard  and  Tom,  Mt.  Pe- 
quawket,  and  farther  south  in  Farmington  and  Rochester.  These  facts 
seem  to  indicate  that  the  White  Mountains  were  considerably  depressed 
during  the  Coos  period,  probably  more  so  than  the  Green  Mountains, 
since  no  slaty  beds  of  this  age  have  been  found  resting  upon  the  Mont- 
alban  or  Huronian  areas  of  Vermont. 

The  Coos  period  was  terminated  by  eruptions  of  sienitic  granite.  The 
conical  Mt.  Ascutney  is  the  best  example  of  this  igneous  material. 
Others  are  Black  mountain,  Dummerston,  the  Washington  and  Essex 
county  mountains,  Vt.,  Iron-ore  hill,  near  Haverhill,  and  the  singular 
concretionary  granite  of  Craftsbury,  Vt.  The  Coos  quartzite  now  con 
stitutes  a  distinct  range  of  mountains. 

At  some  unknown  epoch,  posterior  to  the  consolidation  of  the  andalu- 
site  slates,  there  was  a  considerable  eruption  of  igneous  material,  pro 
ducing  Mts.  Mote  and  Pequawket.  The  paste,  cementing  together  the 
slaty  fragments,  bears  some  resemblance  to  the  Albany  granite,  except 
in  the  abundance  of  dark  spots  commonly  present.  I  think  the  rock  on 
the  top  of  Mt.  Willard  will  probably  turn  out  to  belong  to  the  Mt.  Mote 
series. 

THE  HELDERBERG  PERIOD. 

For  a  very  long  period  of  time  New  Hampshire  furnishes  no  indica 
tion  of  geological  changes.  Our  next  formation  was  deposited  at  the 
very  close  of  the  Silurian  era.  Fossils  have  been  found  which  identify 
the  strata  with  those  of  the  Helderbcrg  mountains  in  New  York. 

The  ocean  must  have  retired  from  the  Connecticut  valley  after  the 
deposition  of  the  Coos  rocks, — otherwise  there  would  have  been  formed 
ledges  to  indicate  the  fact  of  continued  submergence.  The  Helderberg 
ocean  probably  covered  the  same  area  with  the  one  just  described  west 
of  the  Atlantic  ridge,  bordering  the  quartzite.  The  Helderberg  rocks 
occupy  isolated  areas  in  Bernardston,  Mass.,  Hanover,  Lyman,  Lisbon, 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  53Q 

Littleton,  etc.  Most  of  these  patches  contain  crinoidal  and  coralline 
limestones.  It  is  hence  inferred  that  the  Connecticut  valley  was  deeply 
covered  by  the  ocean,  as  polyps  and  crinoids  do  not  flourish  in  limited 
expanses  of  salt  water.  In  New  Hampshire  crinoids,  gasteropods, 
brachiopods,  corals,  and  fucoids  are  known  to  have  flourished.  The 
ocean  probably  supported  in  addition  echinoderms,  trilobites,  large  crus- 
tacea,  and  ganoid  fish.  The  land  may  have  been  covered  with  the  higher 
cryptogams  and  coniferse.  Numerous  hills,  covered  with  vegetation, 
gave  an  unusual  variety  to  the  landscape. 

It  is  difficult  to  note  precisely  the  limits  of  the  Helderberg  ocean. 
There  is  reason  to  believe  that  northern  New  England  and  Canada  sank 
deeper  than  at  any  previous  period,  or  at  any  time  since.  Outcrops  of 
the  Helderberg  rock  abound  in  Quebec  and  northern  Maine.  The 
locality  at  Lake  Memphremagog  may  have  been  connected  with  the 
New  Hampshire  ocean  north  of  Essex  county,  as  the  highest  of  these 
rocks  in  our  state  are  elevated  nearly  one  thousand  feet  above  the  level 
of  the  sea.  I  have  drawn  the  south-eastern  shore  line  to  correspond 
with  the  second  of  our  contour  lines.  The  map  also  indicates  that  no 
evidence  exists  of  a  submergence  in  this  period  in  the  south-eastern  part 
of  the  state. 

The  age  may  be  divided  into  three  periods, — first,  the  epoch  of  the 
deposition  of  sandstone;  second,  of  coralline  limestone;  third,  of  great 
thicknesses  of  slate,  schist,  and  conglomerate.  The  latter  rock  is  com 
posed  chiefly  of  pebbles  derived  from  the  Huronian  and  Atlantic  rocks, 
with  a  few  of  the  Coos  limestones. 

THE  GLACIAL  PERIOD. 

During  the  whole  of  the  Devonian,  Carboniferous,  Permian,  Mesozoic, 
and  Tertiary  periods,  New  Hampshire  stood  above  the  level  of  the  sea, 
and  may  have  included  a  considerable  area  beyond  the  Isles  of  Shoals. 
No  record  has  been  left  of  any  event  that  transpired  within  our  limits 
during  this  immense  lapse  of  time.  The  land  was  probably  covered 
with  vegetation,  and  animals  roamed  over  the  hillsides,  judging  from  the 
conditions  known  to  have  existed  in  the  adjacent  territory.  In  Vermont, 
during  the  early  Tertiary,  there  were  certainly  forests  of  hickory,  beech, 


540 


PHYSICAL    GEOGRAPHY. 


cinnamon,  and  coniferous  trees,  with  a  warm  temperate  climate.     The 
same  must  have  abounded  in  New  Hampshire. 

At  the  close  of  the  Tertiary  period,  ice  began  to  accumulate,  and  there 
was  ushered  in  an  immensely  long  period  when  the  state  was  covered 
with  glaciers,  and  the  climate  corresponded  with  the  present  state  of 
things  in  Greenland.  I  have  no  time  to  enter  fully  into  the  history  of 
this  period.  In  general,  four  periods  are  represented, — first,  when  the 
state  was  entirely  covered  with  glacial  ice  thousands  of  feet  in  thickness 
and  moving  in  a  southerly  direction;  second,  when  local  glaciers  were 
prevalent;  third,  the  Champlain  or  terrace;  fourth,  the  historic  period. 
Our  map  is  designed  to  illustrate  the  movements  of  the  ice  during  the 
first  of  these  periods. 


Fig.  63. — WHITE   MOUNTAIN   RANGE,    FROM   JEFFERSON   HILL. 

Four  special  features  of  ice-motion  are  suggested  by  studying  the 
scorings  upon  the  ledges : — First,  the  greatest  amount  of  work  seems  to 
have  been  accomplished  by  the  south-easterly  direction  of  the  sliding. 
This  course  prevails  over  the  whole  of  Coos  county,  the  White  Moun 
tains,  and  the  higher  peaks  along  the  Connecticut-Merrimack  water 
sheds.  The  highest  markings  preserved  stand  at  5200  feet  above  the 
sea ;  but  transported  pebbles  have  been  picked  up  600  feet  higher,  on  the 
north  slope  of  Mt.  Washington.  This  summit  seems  to  be  the  only  part 
of  the  state  that  has  not  been  subjected  to  glacial  action. 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.

The  ice  in  this  period  pursued  a  south-easterly  course,  with  a  reckless 
disregard  of  all  obstacles.  Mountains  were  scaled  by  the  resistless  mass, 
as  is  proved  by  the  ice  grooves  running  from  base  to  summit,  while  the 
south-easterly  slopes  show  scarcely  any  marks  of  scarification. 

Second,  nearly  all  the  ice  south  of  the  White  Mountains  and  east  of 
the  Connecticut  basin  pursued  a  southerly  course.  Mts.  Monadnock, 
Kearsarge,  and  Ragged  stood  up  as  islands  in  this  ice  sea. 


Fig.  64 — MT.   WASHINGTON,   FROM   THE   GLEN. 

[This  illustration  should  be  compared  with  Fig.  63,  which  shows  the  back  side  of  the  same  mountains,  as  seen 
from  Jefferson  hill.  In  the  first  instance,  the  more  gentle  slope  on  the  north  side  shows  the  smoothing,  rounding 
action  of  the  south-easterly  moving  ice;  while,  in  the  second,  precipitous  sides  illustrate  the  fact  of  no  erosion  by 
the  great  continental  glacier.  As  the  force  moved  south-easterly,  the  ice  would  not  act  upon  the  south-eastern  or 
lee  sides  of  the  mountains.] 

Third,  in  the  Connecticut  valley  south  of  Columbia,  both  in  New 
Hampshire  and  Vermont,  the  ice  moved  a  few  degrees  west  of  south, 
corresponding  with  the  general  course  of  the  valley. 

Fourth,  a  similar  current  passed  down  the  valley  of  Baker's  river  to 


PHYSICAL   GEOGRAPHY. 

Plymouth,  thence  easterly  to  Squam  Like,  thence  south  25°  east  over 
the  Winnipiseogee  basin,  thence  easterly  around  the  south  end  of  Ossipee 
mountain  into  Maine.  Its  course  through  Warren  was  southerly,  and  it 
curved  to  the  east  in  Rumney  before  reaching  Plymouth.  The  variation 
in  direction  corresponds  with  the  course  of  an  extensive  valley. 

A  somewhat  similar  set  of  stri;v  follows  the  Northern  Railroad  from 
Grafton  to  Andover,  passing  down  the  valley  of  the  Blackwater  river 
between  Mts.  Kearsarge  and  Ragged. 

A  very  few  local  glaciers  have  been  observed  about  the  \Yhitc  Moun 
tains.  Somewhat  similar  action. — pushing  gravel  away  from  the  bases 
of  large  hills. — may  bo  observed  in  every  part  of  the  state. 

The  terraces  along  the  Connecticut  and  Merrimack  rivers  give  us 
information  of  the  next  marked  feature  in  post-tertiary  history.  Care 
ful  explorations  along  both  these  rivers  show  that  the  higher  terraces  on 
both  sides  slope  from  the  sources  to  the  mouths,  corresponding  very 
nearly  with  the  fall  of  the  stream.  On  the  Merrimack  the  terraces  in 
Ashland  and  New  Hampton  are  fully  Soo  feet  above  the  ocean ;  at 
Franklin.  470;  at  Concord.  450;  at  Manchester.  250;  and  very  much 
lower  in  Massachusetts.  Similar  phenomena,  though  not  so  marked 
within  our  limits,  may  be  seen  on  the  Connecticut.  \Ye  conclude  that 
at  the  close  of  the  glacial  period,  when  the  ice  was  melting  rapidly,  the 
rivers  filled  their  valleys  even  with  the  tops  of  the  highest  terraces. 
The  terraces  are  lower  and  broader  nearer  the  ocean,  but  would  require 
the  same  amount  of  water  to  cover  them.  \Yhen  the  flow  of  water  had 
diminished,  another  set  of  terraces  was  formed,  lower  than  and  between 
the  first.  In  a  similar  way  the  terraces  still  lower  were  produced. 

During  the  terrace  period  the  land  was  submerged  certainly  about  two 
hundred  feet  and  more,  if  reliance  is  placed  upon  the  argument  from 
maritime  plants  developed  in  a  following  chapter.  Evidence  of  this  state 
of  things  is  afforded  by  the  discover}-  of  marine  shells  and  whales'  ver- 
tebne  in  the  coast  region.  The  boreal  character  of  the  shells  indicates 
a  climate  like  that  of  the  present  GuM  of  St  Lawrence.  During  this 
period  the  woolly  elephant,  wild  boar,  and  primeval  horse  lived  in  the 
wilderness  in  company  with  the  aborigines,  whose  implements  of  stone 
are  so  often  plowed  up  in  our  fields.  These  wild  animals  have  become 
entirely  extinct,  and  the  savages  have  migrated. 


PHYSICAL    HISTORY    OF    NEW    HAMPSHIRE.  543 

Subsequently  to  the  cold  term  indicated  by  the  boreal  marine  shells, 
there  are  two  classes  of  facts  serving  to  indicate  since  that  time,  and 
probably  within  the  human  period,  a  long  era  when  the  climate  over 
New  Hampshire  was  milder  than  it  is  now.  The  evidences  derived  from 
our  limits  are  the  scanty  remains  of  southern  plants  procured  in  a  very 
few  localities.  They  may  be  well  represented  by  the  Rhododendron  max 
imum,  mentioned  in  the  catalogue  of  plants  as  occurring  in  Richmond, 
Fitzwilliam,  and  Grantham.  Since  the  printing  of  that  chapter,  I  have 
got  traces  of  it  in  Hopkinton  and  Hooksett.  The  proper  home  of  this 
shrub  is  in  the  Middle  states.  Its  occurrence  in  insulated  swamps  sug 
gests  a  former  abundance  in  intermediate  localities,  and  the  presumption 
of  a  climate  more  like  that  of  Pennsylvania,  to  enable  it  to  flourish 
within  our  borders. 

The  other  class  of  facts  is  represented  by  the  discovery  of  several 
kinds  of  marine  animals  that  properly  flourish  south  of  Cape  Cod,  on 
the  coast  of  Maine,  and  the  British  provinces.  The  nearest  locality  is  at 
Quahog  bay,  about  thirty  miles  beyond  Portland.  More  than  twenty 
species  of  marine  animals,  according  to  Prof.  Verrill,  live  in  this  bay,  the 
most  common  of  which  is  the  quahog  or  round  clam,  whose  proper  hab 
itat  lies  to  the  south  of  Massachusetts  bay.  Scarcely  any  of  them  are 
known  to  occur  off  the  New  Hampshire  coast.  In  their  stead  are  the 
more  northern  species,  such  as  are  at  home  in  the  waters  of  the  Can 
adian  district.  This  assemblage  of  extra-limital  species  is  called  a 
"colony,"  and,  in  order  to  understand  why  they  live  in  such  a  place,  iso 
lated  from  their  kindred,  we  may  use  the  same  theory  which  has  just 
been  applied  to  the  occurrence  of  the  Rhododendron.  The  climate  for 
merly  allowed  the  Alleghanian  animals,  as  well  as  plants,  to  abound 
where  now  the  colder  Canadian  species  find  the  conditions  of  life  con 
genial,  and  suitable  for  productiveness. 

Another  of  these  southern  forms  is  the  oyster.  This  occurs,  living 
naturally,  in  the  Sheepscot  and  Harriseeket  rivers  in  Maine.  It  is  sup 
posed  that  both  these  edible  mollusks  once  flourished  along  the  whole 
coast.  Further  evidence  is  afforded  by  the  discovery  of  numerous  heaps 
of  their  shells  in  the  piles  of  rubbish  left  by  the  aborigines,  who  used 
the  animals  for  food.  These  heaps  occur  very  commonly  along  the 
whole  New  England  coast;  and  they  seem  to  indicate  that  this  milder 


544  PHYSICAL    GEOGRAPHY. 

climate  belonged  to  the  early  part  of  the  human  period,  else  the  kitchen 
rubbish  has  no  significance. 

A  similar  colony  is  said  to  exist  in  the  Gulf  of  St.  Lawrence.  Their 
continued  existence  in  the  Gulf  and  Casco  bay  may  be  explained  in  the 
same  way.  Both  these  bodies  of  water  are  comparatively  shallow.  This 
fact  prevents  the  flow  into  them  of  the  cold  arctic  current  from  the 
north,  and  allows  the  heat  of  the  sun  in  the  summer  to  moderate  the 
temperature  very  considerably.  The  tides  are  not  very  powerful  in  these 
bays, — certainly  not  like  the  enormous  ebb  and  flow  in  the  Bay  of  Fundy, 
where  the  southern  animals  do  not  exist  The  moderate  tide  prevents 
the  thorough  mingling  of  the  cold  and  warm  waters,  and  this  is  favora 
ble  to  the  continuance  of  the  colonies. 

The  changes  in  the  temperature  of  the  bays  seem  therefore  to  be  local 
in  character,  and  to  be  readily  accounted  for  by  variations  in  the  relative 
level  of  land  and  water.  The  deepening  of  the  bays  and  the  influx  of 
the  arctic  current  might  kill  off  the  more  delicate  animals,  and  thus 
exterminate  the  colonies ;  or,  with  the  development  of  other  contiguous 
shallow  areas,  the  inhabitants  may  migrate  to  more  salubrious  climes. 
Could  we  become  better  acquainted  with  the  present  distribution  of  live 
animals  on  the  land  and  beneath  the  water  off  the  coast  of  New  Hamp 
shire,  still  other  chapters  might  be  added  to  our  history. 

I  have  now  given  a  brief  outline  of  the  physical  history  of  New  Hamp 
shire.  Commencing  with  mere  points  of  dry  land,  we  have  seen  how  the 
territory  has  increased  in  size  from  age  to  age,  and  have  appreciated  the 
fact  that  the  state  is  quite  ancient, — almost  the  oldest  land  in  America. 
For  much  of  geological  time  the  record  has  been  meagre.  Entire  races 
have  peopled  its  surface,  and  left  behind  no  evidence  of  their  existence. 
No  doubt  the  wonderful  birds,  which  left  their  footmarks  along  the  Con 
necticut  valley  in  Massachusetts,  built  their  nests  among  the  jungles  of 
New  Hampshire,  from  whence  they  often  emerged  in  search  of  food. 
And  in  the  Carboniferous  period  immense  forests  must  have  covered  our 
hillsides,  even  more  luxuriant  than  the  original  growth  which  furnished 
so  many  magnificent  masts  for  the  royal  navy  of  England.  The  last  is 
the  greatest  of  all  the  periods  in  our  history.  Man,  the  crowning  mas 
ter-piece  of  creation,  has  been  introduced.  The  silence  of  the  forests  is 
broken  with  the  axe ;  the  savage  beasts  and  aboriginal  men,  their  com-

rades,  melt  away  before  the  palefaces ;  railroads  wind  among  the  hills, 
climbing  even  to  the  top  of  Mt.  Washington ;  and  the  state  is  inhabited 
by  the  most  vigorous  of  the  Anglo-Saxon  race.  Those  who  have  been 
trained  in  our  schools  have  gone  forth  to  lead  in  the  councils  of  state, 
and  to  be  foremost  in  maintaining  right  and  justice.  The  last  is  the 
best  of  all  the  periods.  May  its  record  grow  brighter  and  more  glorious 
to  the  end  of  time!

CHAPTER  XVI. 

THE  RELATIONS  OF  GEOLOGY  TO  AGRICULTURE. 

presenting  briefly  the  relations  of  geology  to  agriculture,  as  espe 
cially  applied  to  New  Hampshire,  it  seems  proper  first  to  state  a 
few  fundamental  facts,  and  then  present  the  details  that  more  immedi 
ately  concern  us. 

The  first  inquiry  in  agricultural  geology  is,  What  is  the  composition  of 
good  soils  ? 

The  matter  in  all  soils  capable  of  sustaining  vegetation  exists  in  two 
forms, — inorganic,,  and  organic.  The  first  contains  twelve  chemical  ele 
ments,  viz.,  oxygen,  sulphur,  phosphorus,  carbon,  silicon,  and  the  metals 
potassium,  sodium,  calcium,  aluminum,  magnesium,  iron,  and  manganese. 
In  the  organic  part  the  elements  are  four, — oxygen,  hydrogen,  carbon, 
and  nitrogen.  The  inorganic  elements  are  derived  from  the  rocks ;  the 
organic  elements  from  decaying  animal  and  vegetable  matter, — so  that  it 
is  of  the  earthy  constituents  we  must  speak.  They  do  not  indeed  occur 
in  their  simple  state,  but  as  water,  sulphates,  phosphates,  carbonic  acid, 
silicates  of  potassa,  soda,  lime,  magnesia,  alumina,  iron,  etc.  The  aver 
age  amount  of  silicates  or  sand  in  soil  is  eighty  in  one  hundred  parts. 

The  second  inquiry  is,  whether  these  elements  of  the  soil  are  found 
in  the  rocks.  By  consulting  the  details  of  their  analyses,  as  given  in 
geological  treatises,  it  will  be  seen  that  they  are  all  present  except  phos 
phorus,  which,  however,  is  not  unfrequcntly  found  in  them  in  the  condi 
tion  of  phosphates.  Moreover,  the  proportion  of  the  ingredients  in  the 


THE  RELATIONS  OF  GEOLOGY  TO  AGRICULTURE.          547 

rocks  docs  not  differ  much  from  that  of  the  soils.  Ilcncc  the  conclusion 
is  that  the  latter  are  only  the  former  comminuted,  with  the  addition  of 
from  three  to  ten  per  cent,  of  organic  matter. 

Since  the  rocks  differ  considerably  in  composition,  we  should  expect  a 
corresponding  difference  in  the  soils  derived  from  them.  And  such  is 
the  fact  to  a  considerable  extent,  where  the  soil  is  simply  the  result  of 
the  disintegration  of  the  rock  beneath  it.  It  is  enough  so  in  many  dis 
tricts  to  form  characteristic  soils.  Thus,  over  quartz  rocks  and  some 
sandstones  we  find  a  very  sandy  and  barren  soil,  though  it  is  said  that 
in  nearly  all  soils  enough  silicates  of  lime  and  magnesia  arc  present  to 
answer  the  purposes  of  vegetation  ;  but  the  alkalies  and  phosphates  may 
be  absent.  When  the  rock  is  limestone,  the  soil  is  sometimes  quite  bar 
ren  for  the  want  of  other  ingredients,  and  also  in  consequence  of  the  dif 
ficulty  of  decomposition.  Clay,  also,  may  form  a  soil  too  tenacious  and 
cold.  The  sandstones  that  contain  marly  beds,  and  some  of  the  tertiary 
rocks  of  analogous  character,  form  excellent  soils.  So  docs  clay  slate, 
and  especially  calciferous  mica  schist.  The  amount  of  potash  and  soda 
in  gneiss  and  granite  often  makes  a  rich  soil  from  these  rocks,  and  the 
trap  rocks  form  a  fertile  though  scanty  soil. 

But,  in  the  third  place,  in  most  countries,  aqueous  and  glacial  agencies 
have  so  mixed  the  soils  together  that  their  original  peculiarities  are  lost, 
and  new  and  compound  characters  are  given  them.  This  is  particularly 
the  case  in  northern  countries,  where  the  drift  agency  has  swept  over  the 
surface,  and  torn  off  and  mixed  together  the  disintegrated  portions  of  the 
several  formations.  Subsequently  rains  and  streams  have  carried  the 
finer  portions  of  the  drift  into  the  lowest  places,  and  there  formed  allu 
vial  meadows,  and,  although  these  are  usually  the  best  of  soils,  they  are 
often  derived  from  many  different  rocks.  The  drift  left  upon  the  higher 
grounds  is  generally  quite  barren,  chiefly  because  of  its  coarseness. 

A  fourth  service  which  the  geologist  renders  to  agriculture  is  by  the 
discovery  of  fertilizers.  Sometimes  he  can  point  out  deposits  of  the 
phosphates,  either  in  a  crystalline  state,  or  as  coprolitcs  or  guano.  He 
can  also  show  what  rocks  contain  carbonate  of  lime,  or  discover  sulphate 
of  lime,  or  marl  beds,  or  greensand,  or  decomposing  fossil  shells,  or  de 
posits  of  carbonaceous  matter.  Me  can  also  find  what  rocks  contain 
enough  of  potash  or  soda  to  be  of  service  when  pulverized. 


548  PHYSICAL  GEOGRAPHY. 

THE  SOILS  OF  NEW  HAMPSHIRE. 

The  soils  of  New  Hampshire  are  divided  into  four  kinds,  upon  the 
little  map  herewith  presented.  They  are  arranged  in  the  order  of  their 
value.  First,  we  have  those  derived  from  calcareous  rocks,  and  exhibited 
in  the  Connecticut  river  valley  near  Colebrook  and  Claremont.  Second, 
the  balance  of  this  hydrographic  basin  is  occupied  by  more  or  less  slaty 
and  schistose  rocks.  These  are  somewhat  calcareous,  and  decidedly  mag- 
nesian.  Third,  the  rocks  bordering  the  coast  in  Rockingham  county, 
and  extending  northerly  up  Piscataqua  river,  produce  a  very  similar  soil. 
Fourth,  the  rest  of  the  state  is  underlaid  by  gneiss  and  granite,  produc 
ing  several  grades  of  soil,  according  to  particular  local  character. 

In  a  subsequent  chapter  I  shall  show  a  map  indicating  what  proportion 
of  the  state  is  now  covered  by  a  forest  growth.  By  comparing  this  with 
the  agricultural  map,  it  will  be  easy  for  the  pioneer  to  know  where  he 
can  find  the  best  virgin  soil  within  our  limits.  The  same  map,  and  also 
one  in  Chapter  XIII,  shows  what  proportion  of  the  state  is  situated 
above  the  limit  of  trees.  Both  these  maps  will  be  useful  in  studying  the 
agricultural  capacities  of  our  domain.  It  was  not  desirable  to  incorpo 
rate  the  forest  and  the  barren  ground  districts  with  the  agricultural  map, 
else  comparisons  of  the  kind  of  soil  with  the  areas  of  wood-growth 
and  arctic  vegetation  would  have  been  impracticable. 

THE  CALCAREOUS  SOILS. 

It  is  well  known  that  the  soils  in  eastern  Vermont  are  of  a  supe 
rior  character.  I  refer  to  those  in  the  eastern  part  of  Orleans  county, 
most  of  Caledonia  and  Orange,  and  the  eastern  border  of  Windsor  and 
Windham  counties.  These  lands  produce  more  in  proportion  to  their 
valuation  and  inhabitants  than  the  other  districts  east  of  the  Green 
Mountains ;  and,  as  the  climate  and  general  topographical  features  are 
the  same,  the  reason  of  their  greater  fertility  must  lie  in  the  chemical 
character  of  the  soil.  Limestone  countries  are  everywhere  fertile. 

The  geological  survey  has  been  the  first  to  discover  the  existence  in 
New  Hampshire  of  considerable  areas  of  this  formation.  The  ledges 
are  composed  of  alternations  of  bluish  siliceous  limestone,  clay  slate,

and  mica  schist,  which,  by  the  action  of  the  air,  rain,  and  frost,  readily 
decompose,  and  the  lime  and  other  fertile  ingredients  are  leached  out 
and  diffused  through  the  soil,  where  the  roots  of  the  growing  crops  can 
readily  assimilate  them.  In  consequence  of  this  ready  decomposition  of 
the  ledges,  every  small  stream  has  excavated  very  much  material ;  and 
this  region  is  full  of  steep  hills,  often  conical.  These  steep  hillsides 
are  fertile,  as  may  be  instanced  in  the  towns  of  Cornish  and  Lyme. 

Furthermore,  there  are  considerations  tending  to  show  that  the  adja 
cent  granite  hills  are  benefited  by  the  proximity  of  the  limestones.  The 
study  of  theoretical  geology  seems  of  little  practical  importance  to  many 
people ;  but,  by  examining  scratches  upon  ledges,  and  other  phenomena 
on  the  surface,  we  can  say  positively  that  immense  masses  of  ice  once 
travelled  over  the  state  in  a  general  southerly  direction  (but  varying 
greatly  in  different  portions  of  the  state).  This  ice,  in  its  onward  prog 
ress,  broke  off  fragments  of  the  ledges,  and  distributed  them  over  the 
country.  Hence,  as  the  granite  region  lay  in  the  path  of  this  mighty 
stream,  blocks  of  limestone  came  over  its  surface,  and,  by  their  de 
composition,  have  tended  to  improve  the  soil.  These  may  be  found 
throughout  the  western  border  of  the  gneissic  region  from  Dixville  to 
Hinsdale. 

Another  benefit  comes  from  the  presence  of  the  calcareous  rocks.  By 
their  decomposition,  numerous  small  molluscous  animals  are  enabled  to 
obtain  the  material  for  their  shells.  They  consequently  abound  in  calca 
reous  countries,  since  they  here  find  one  of  the  essentials  to  their  exist 
ence  in  great  abundance.  The  aquatic  tribes  of  mollusks  exist  in  such 
great  numbers  that  their  remains  accumulate  at  the  bottom  of  ponds  in 
deposits  several  feet  thick.  More  than  thirty  of  these  beds  are  described 
in  the  geology  of  Vermont,  in  the  region  just  spoken  of.  I  have  seen  as 
yet  only  two  in  New  Hampshire, — one  in  Columbia,  and  the  other  in 
Brookline.  The  lime  is  nearly  pure,  and  can  be  burned  for  quick-lime, 
or  spread  upon  the  land  fresh  from  the  swamp.  The  pond-way  has  dis 
appeared  by  filling  up,  and  remains  only  as  a  swamp.  The  importance 
of  these  marl  beds  makes  it  desirable  for  those  living  upon  the  calca 
reous  regions  to  search  further.  It  would  give  me  great  pleasure  to  visit 
any  deposit  of  this  kind  that  may  be  discovered  by  the  farmers  within 
our  state  limits.  The  farmers  will  understand  that  lime  and  plaster  are 


5 SO  PHYSICAL    GEOGRAPHY. 

not  so  essential  to  the  growth  of  crops  in  the  calcareous  areas  as  else 
where.  Nevertheless,  I  have  observed  that  where  lime  is  the  most 
abundant,  the  farmers  are  apt  to  use  a  great  deal  of  it,  even  burning  it 
for  their  own  use  from  the  ledges  on  their  acres.  If  chemical  analyses 
are  reliable,  we  ought  to  find  large  returns  of  potatoes,  peas,  beans, 
clover,  and  rye  from  the  calcareous  area. 

Besides  the  sources  of  lime  mentioned,  there  are  beds  of  the  best 
quality  of  limestone  for  agricultural  purposes  in  Plainfield,  Lyme,  Orford, 
Haverhill,  Lisbon,  Lyman,  Littleton,  and  elsewhere.  Nothing  except  a 
demand  for  the  manufactured  lime  is  necessary  to  cause  the  proprietors 
of  these  beds  to  produce  this  valuable  mineral  in  large  quantities. 

Slaty  Soils.  Of  the  two,  the  slaty  soils  of  the  Connecticut  valley  are 
superior  to  those  along  the  coast.  The  rock  is  apt  to  be  a  schist  con 
taining  much  alumina,  a  little  lime  and  magnesia,  and  ten  or  twelve  per 
cent,  of  soda  and  potassa ;  other  members  are  soft  slates,  which  are  rich 
in  alumina,  and  sometimes  lime.  The  area  south  of  Claremont  is  more 
apt  to  contain  lime  than  potassa.  When  pulverized  by  the  ice  of  the 
drift  period,  they  give  rise  to  beds  of  clay.  The  second  class  of  slaty 
soils  receives  many  boulders  of  granite  through  ice  transportation,  which 
are  not  so  beneficial  as  the  lime  brought  into  the  Connecticut  valley  from 
Vermont  and  Canada. 

Granitic  Soils.  The  greater  portion  of  the  state  is  underlaid  by  gneiss. 
This  is  practically  the  same  as  granite; — so  that  the  words  granite  and 
gneiss  convey  the  same  meaning,  so  far  as  mineral  composition  is  con 
cerned.  I  think  that  the  gneiss  is  apt  to  produce  better  soils  than 
granite.  The  soluble  element  present  is  usually  potash,  from  ten  to 
twelve  per  cent.  This  is  certainly  a  very  valuable  substance  to  be  added 
to  the  soil;  and  nature  is  crumbling  down  the  granites  continually.  It 
is  done  by  the  action  of  the  atmosphere.  The  burning  of  wood  and 
coal  sends  out  carbonic  acid.  Whatever  of  this  is  not  utilized  by  grow 
ing  plants  is  left  in  the  air  to  be  dissolved  in  rain-water.  The  rain  soaks 
into  the  rocks,  and  thus  the  acid  acts  upon  the  feldspars,  setting  free  the 
potash,  perhaps  combining  with  it  to  form  the  carbonate  (or  saleratus). 
Should  this  mix  with  earth,  the  result  will  be  beneficial  to  the  crops.  I 
doubt  not  that  the  pulverization  of  granite  will  benefit  soils.  No  one 
could  expect  to  accomplish  great  things  in  this  way,  since  the  decompo-

sition  is  gradual;  but  it  would  seem  as  if  the  constant  destruction  of 
granites,  by  hammers  and  fires,  would,  in  the  course  of  years,  tend  to 
remove  unsightly  rocks,  and  to  improve  the  soil. 

Several  varieties  of  soil  occur  in  the  granitic  region.  High  up  many 
of  the  mountains  the  granites  are  bare,  and  allow  little  place  for  the 
accumulation  of  organic  matter.  When  the  valleys  are  wide,  the  better

part  of  the  rock  and  other  substances  accumulate,  as  in  Fig.  66;  so  that 
after  a  while  many  farmers  find  they  can  allow  their  hills  to  revert  to 
timber,  and  cultivate  the  original  bogs  and  swamps  with  better  success. 
Again,  the  soil  is  mixed,  in  consequence  of  the  abundance  of  diverse 
drift  material.  This  is  generally  an  improvement.  Another  variety  is 
found  in  the  sandy  plains  of  Carroll  county,  and  the  high  terraces  along 
the  Merrimack.  The  current  of  ancient  times  was  just  strong  enough 
to  wash  away  the  coarser  particles  into  deposits  by  themselves,  leaving 
the  finer  particles  to  form  clays.  An  instance  of  this  segregation  is  seen 
at  Hooksett,  where  this  clay  is  used  for  bricks,  while  the  sand  is  accu 
mulated  in  piles  by  itself.

THE  EXACT  COMPOSITION  OF  OUR  SOILS. 

In  addition  to  our  general  description  of  the  soils  of  the  state,  it 
may  be  desirable  to  present  analyses  of  them  from  different  localities. 
Dr.  Jackson,  in  his  final  report,  gave  the  results  of  a  large  number, 
which  I  will  reproduce  in  the  form  of  a  table.  In  analyses  made  at  the 
present  day,  greater  attention  is  paid  to  the  determination  of  phosphoric 
acid,  the  alkalies,  and  nitrogenous  compounds,  than  appears  to  have  been 
devoted  to  the  subject  by  Dr.  Jackson.  The  table  will  show  the  average 
composition  of  the  soils  of  the  state,  in  respect  to  insoluble  silicates,  the 
peroxide  of  iron,  alumina,  lime  and  its  compounds,  magnesia,  and  the 
organic  matter.  The  column  stating  the  percentage  of  water  is  not  of 
any  practical  importance.  In  a  few  cases  special  determinations  were 
made  of  the  organic  matter,  the  following  being  invariably  present:  "(i) 
Crenic  acid  and  crenates  of  bases;  (2)  apocrenic  acid,  combined  also 
with  bases ;  (3)  humic  acid,  combined  also  with  bases ;  (4)  humic,  or  neu 
tral  undecomposed  vegetable  matter;  (5)  extract  of  humus,  and  (6)  a 
second  extract,  not  yet  named,  separated  from  the  above ;  (7)  phosphoric 
acid  in  minute  quantities."

PHYSICAL    GEOGRAPHY. 


Dr.  Jackson  prepared  an  extensive  sketch  of  the  relations  of  geology 
to  agriculture,  to  which  the  attention  of  those  interested  in  the  subject 
is  invited,  on  account  of  the  many  valuable  suggestions  contained  in  it. 

USE  OF  FERTILIZERS. 

Formerly  it  was  thought  that  the  mineral  constituents  of  plants  were 
of  no  great  consequence  in  their  growth.  Experimental  research  indi 
cates  that  certain  proportions  of  various  mineral  elements  are  essential 
to  the  perfect  growth  of  a  plant,  and-  that  if  the  proper  ash-constituents 
are  not  supplied,  every  part  may  be  vigorously  developed  except  the  seed. 
These  researches  have  led  to  the  extensive  introduction  of  mineral  fertil 
izers. 

In  order  to  understand  what  kind  of  fertilizers  should  be  applied 
to  the  soil,  the  farmer  should  know,  first,  the  exact  composition  of  his 
ground ;  second,  of  his  crops ;  and  third,  of  the  proper  fertilizers  to  be 
applied.  The  statements  already  given  will  show  in  general  the  compo 
sition  of  the  soils  of  the  state.  For  more  exact  information,  special 
determinations  should  be  made  in  each  case.  It  will  be  possible  to  pre 
sent  a  few  general  statements  in  respect  to  the  composition  of  the  more 
common  farm  products  and  commercial  fertilizers.  These  analyses  will 
be  a  safe  guide  when  one  wishes  to  know  what  fertilizers  must  be  applied 
to  the  soil  in  order  to  restore  what  has  been  abstracted  from  it  by  the 
removal  of  the  several  crops.  The  tables  are  derived  from  an  essay  on

commercial  fertilizers  by  Prof.  C.  A.  Goessmann,  in  the  tenth  annual 
report  to  the  Massachusetts  Agricultural  College,  January,  1873. 

The  first  table  shows  the  amount  and  kind  of  plant-food  contained 
in  one  thousand  pounds  of  various  air-dried  substances. 

Stable  manure  is  one  of  the  most  important  fertilizers, — yet  its  pecu 
liar  value  depends  more  on  its  influence  upon  the  physical  condition  of 
the  soil  than  its  chemical  composition.  The  following  statement  will 
show  its  chemical  character  in  various  stages  of  disintegration.  One 
thousand  pounds  contained  (Wolff.), —

The  following  analyses  by  Dr.  Goessmann  were  made  from  samples 
taken  from  the  original  packages  in  which  they  were  placed  for  sale  by 
the  manufacturers.  As  the  farmer  does  not  propose  to  pay  for  anything 
but  phosphoric  acid,  nitrogen  (or  ammonia),  and  potassa,  the  results  are 
given  with  particular  reference  to  these  substances.  The  valuation  of 
these  articles  has  been  made  in  conformity  with  the  prices  of  late  recog 
nized  by  dealers  and  consumers  in  our  section  of  the  country.  These 
prices  are  16.25  cents  for  each  pound  of  soluble  phosphoric  acid,  13.2 
cents  for  every  pound  of  reduced  phosphoric  acid,  6  cents  for  every 
pound  of  insoluble  phosphoric  acid,  30  cents  for  each  pound  of  nitro 
gen,  and  8  cents  for  each  pound  of  potassa.  Reduced  phosphoric  acid 
is  that  portion  which  has  apparently  once  been  rendered  soluble  in 
water,  but  has  become  insoluble  again  in  consequence  of  peculiar  reac 
tions  which  sometimes  occur  in  the  manufactured  fertilizer.  Its  com 
pound  with  lime  is  soluble  in  citrate  of  ammonia,  and  in  a  suitable  condi 
tion  for  speedy  absorption  under  the  influence  of  the  carbonic  acid  of 

the  soil.

CHAPTER     XVII. 

REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS. 

.HE  object  of  this  chapter  is  to  present  a  few  additional  facts  re 
specting  the  distribution  of  animals  and  plants,  and  endeavor  to 
deduce  from  all  that  is  known  the  precise  boundaries  between  the  Can 
adian  and  Alleghanian  districts ;  and  to  call  the  attention  of  botanists 
to  the  importance  of  drawing  the  lines  between  the  alpine  and  sub-alpine 
floras.  The  determination  of  these  questions  requires  the  application 
of  a  knowledge  of  our  isothermal  lines, — both  for  summer  and  winter 
temperature, — the  contour  lines  of  elevation  above  the  sea,  and  the 
actual  limits  of  the  distribution  of  the  principal  animals  and  plants. 

THE  DISTRIBUTION  OF  BIRDS. 

From  the  writings  of  prominent  ornithologists,  it  is  now  possible  to 
ascertain  the  geographical  limits  within  which  the  different  species  of 
birds  rear  their  young.  On  account  of  their  migratory  habits,  the  birds 
are  reckoned  to  belong  to  those  regions  where  they  breed.  Very  many 
arctic  birds  are  seen  within  our  limits,  especially  during  the  winter,  but 
these  are  not  to  be  classed  among  New  Hampshire  birds.  The  lists 
herewith  appended  are  not  exhaustive ;  but  I  have  taken  pains  to  present 
only  those  names  which  are  stated  to  breed  within  our  limits,  by  compe 
tent  authorities.  It  will  be  quite  desirable  to  collect  facts  respecting  the 
breeding  of  birds  along  the  Connecticut-Merrimack  water-shed,  since 
certain  Canadian  species  may  be  found  farther  south  along  this  line 
than  has  been  heretofore  supposed.

REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       563 

THE  DISTRIBUTION  OF  INSECTS. 

At  my  request,  Mr.  C.  P.  Whitney,  of  Milford,  visited  the  southern 
part  of  Cheshire  county,  in  the  early  part  of  August  (1874),  with  the  view 
of  ascertaining  whether  some  of  the  more  northern  species  of  insects 
extended  farther  south  than  the  latitude  of  Milford.  The  season  proved 
to  be  an  unfavorable  one  for  observing  characteristic  species,  partly 
because  of  stormy  weather,  and  partly  because  the  most  peculiar  forms 
usually  make  their  appearance  earlier  in  the  summer. 

Concerning  the  fauna  of  Mt.  Monadnock,  Mr.  Whitney  writes, — 
"Although  about  the  summit  I  found  flora  corresponding  to  the  sub- 
alpine  of  the  White  Mountains,  I  met  with  no  insects  except  such  as 
are  found  below,  and  of  those  but  few." 

Concerning  the  insects  south  of  the  mountain  he  writes, — "To  the 
south  of  the  mountain  in  Jaffrey,  Rinclge,  etc.,  I  found  Minois  Alope 
(which  I  can  hardly  regard  as  Canadian)  in  abundance;  also,  Basilar- 
cJiia  ArtJicmis,  Grapta  Faunns  (Polygonia  of  Scudder),  J.  album,  A. 
bombyx,  and  Ctenucka  Virginica. 

"Although  owing  to  the  continued  rainy  weather  I  met  with  but  little 
success,  I  am  satisfied  those  towns  possess  a  more  northern  fauna  than 
Milford  and  its  vicinity, — whether  enough  so  to  place  them  in  the  Can 
adian  region  (if,  indeed,  a  division  is  practicable),  I  cannot  determine. 

"I  wish  to  call  your  attention  to  a  few  instances  which  conflict  more 
or  less  with  Mr.  Scudder's  text.  The  numbers  are  those  of  his  list. 

"4.  NepJiclc  is  not  found  in  the  southern  part  of  the  state. 

"ii.  Mr.  Hutchinson  has  taken  a  specimen  of  interrogationis  at  Han 
over. 

"24.  I  have  seen  Aphrodite  in  the  sub-alpine  region  of  Mt.  Wash 
ington. 

"35.  Edwardsii  has  never  been  taken  here  [Milford]. 

"69.  Vialis  is  common  in  the  lowlands  of  this  vicinity;  and  I  have 
found  it  abundant  both  in  the  Glen  (White  Mountains)  and  at  Dixville 
notch,  in  the  northern  extremity  of  the  state. 

"71.  Paniscus  (Mandan)  I  have  taken  at  Colebrook;  and  Mr.  Mor 
rison  took  one  specimen  in  the  Glen. 

"73.  Massasoit  has  not  been  seen  here.

"8  r.  Manataaqua  is  found  here  occasionally. 
"84.  Vcrna  has  never  been  taken  in  this  vicinity. 

"(Ecanthus  nivcus,  Phylloptera  oblongifolia,  and  Arphia  sulphured  are 
common  here." 

THE  DISTRIBUTION  OF  PLANTS. 

I  have  quite  a  number  of  additional  facts  to  present  upon  the  distri 
bution  of  plants,  and  will  notice,  first,  certain  features  of  the  maritime 
species ;  then  of  the  alpine  forms ;  and  afterwards  remark  upon  the 
areas  covered  by  forests. 

Maritime  Plants. 

The  catalogue  of  plants  gives  the  names  of  thirty-seven  species  fre 
quenting  the  sea-shore,  and  six  more  will  probably  be  discovered  within 
our  limits.  Botanists  suppose,  as  these  plants  are  mainly  confined  to 
the  neighborhood  of  the  ocean,  that  the  impregnation  of  the  atmosphere, 
and  perhaps  soil,  with  saline  materials  determines  their  habitat.  It  hap 
pens  that  many  of  them  occur  in  connection  with  salt  deposits  in  western 
New  York,  etc. ;  along  the  St.  Lawrence  river  and  the  great  lakes,  and 
in  saline  regions  among  the  Rocky  Mountains.  A  little  reflection 
upon  the  facts  that  will  be  presented  will  show  that  the  distribution  of 
these  maritime  plants  in  North  America  may  be  a  proof  of  oceanic  sub 
mergence  in  the  period  intervening  between  the  age  of  ice  and  historic 
time. 

American  botanists  have  frequently  recorded  the  presence  of  mari 
time  phenogamous  plants  in  the  interior  of  the  continent,  and  have 
commented  upon  the  singularity  of  the  circumstance.  For  example, 
Prof.  J.  A.  Paine,  Jr.,  in  the  Regents'  Report  of  the  New  York  State 
Cabinet  for  1865,  enumerates  Juncus  Balticns  among  the  plants  of  Gen- 
esee  county,  at  a  locality  over  three  hundred  feet  above  Lake  Ontario, 
and  twenty  miles  south  of  it,  associated  with  Zygadcnus  glaucus  and 
Solidago  Houghtonii,  found  only  on  the  north  shore  of  Lake  Michigan. 
It  is  a  sea-side  plant,  native  in  the  northern  European  and  American 
coasts.  "For  its  introduction  to  the  great  lakes  it  is  just  as  dependent 
on  the  ocean  as  are  Ranunculus  Cymbalaria,  Atriplcx  hastata,  Salicornia 
herbasea,  Najas  major,  Ruppia  maritirna,  Trigoclin  maritimum,  Juncus 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       565 

bnlbosus,  Scirpus  maritimns,  and  Spartina  stricta,  for  their  existence  at 
Onondaga  lake,  and  LatJiyrns  maritimns  on  the  banks  of  Oneida  lake." 
He  then  conjectures  that  in  some  past  geological  period  the  land  was 
submerged,  and  the  ocean  extended  into  the  interior. 

In  the  Canadian  Naturalist  for  May,  1 867,  A.  T.  Drummond,  B.  A., 
LL.B.,  sets  forth  similar  facts,  and  mentions  twenty  species  of  maritime 
plants  that  have  been  found  in  the  interior.  He  refers  the  origin  of  this 
distribution  to  the  presence  of  salt  water  in  the  great  lakes  in  the  Post- 
Pliocene  or  Champlain  period,  subsequent  to  the  glacial  drift.  As  the 
waters  gradually  became  fresh,  some  of  the  species  would  be  extermi 
nated,  and  others  become  reconciled  to  the  changed  conditions,  and 
remain  as  monuments  to  this  ancient  oceanic  prolongation  into  the  inte 
rior  of  the  continent. 

A  few  years  since  I  made  inquiries  of  botanists  for  catalogues  of 
plants  along  the  great  lakes,  St.  Lawrence  and  Hudson  river  valleys, 
and  published  in  the  Proceedings  of  the  American  Association  for  the 
Advancement  of  Science*  a  brief  statement  of  the  facts  obtained,  with 
details  respecting  the  occurrence  of  the  species  in  the  several  localities. 

There  are  seventy-nine  species  in  this  list.  Of  these,  seven  are  noted 
as  doubtful,  since  they  may  not  be  confined  in  their  range  to  the  sea 
shore.  The  following  may  be  legitimately  added  to  the  doubtful  list: 
Zygadcnus  glaucus,  Solidago  Honghtonii,  and  Corispermum  Jiyssopifo- 
lium.  These  occur  in  the  interior,  and  not  on  the  coast  The  last,  with 
Najas  major,  are  not  on  the  American,  but  flourish  on  the  European 
coast.  Add,  also,  Lobelia  Kalmii,  Rkyncospora  capillacea,  Scleria  verti- 
cillata,  Scirpns  pungens,  and  Polanisia  graveolens,  which,  upon  a  careful 
examination,  may  prove  to  belong  to  the  maritime  type ; — certainly,  so 
far  as  known,  their  distribution  corresponds  with  that  of  the  seventy- 
nine  in  the  table.  These  eight,  added  to  the  seventy-nine,  make  a  total 
of  eighty-seven. 

Of  this  list,  following  Grays  Manual  of  Botany,  twenty-two  are  found 
on  the  coast  north  of  New  York,  six  south  of  the  same,  thirty  (including 
Juncus  Vaseyi,  on  the  authority  of  Dr.  T.  C.  Porter)  occur  mostly  south 
of  New  England,  and  twenty-two  are  found  along  the  whole  of  our  east 
ern  shore.  Thirty-three  of  them,  or  only  ten  less  than  the  whole  number

occurring  on  the  coast  north  of  New  York,  are  found  in  the  interior,  dis 
tributed  as  follows:  Lower  St.  Lawrence  waters,  five;  Lake  Ontario, 
nine ;  salt  region  of  western  New  York,  seventeen ;  Lake  Erie,  seven 
teen  ;  Lake  Huron,  twelve ;  Lake  Michigan,  fourteen ;  Lake  Superior, 
fifteen ;  Minnesota,  seven ;  Hudson  river,  only  one ;  Lake  Champlain, 
three;  and  Hudson's  bay,  three. 

Theory.  The  proper  explanation  of  the  distribution  of  maritime  plants 
has  been  already  shadowed  forth  in  the  comments  of  Messrs.  Paine  and 
Drummond.  Following  the  glacial  period,  geologists  believe  the  land  of 
northern  America  has  been  submerged  several  hundred  feet,  as  shown 
by  the  remains  of  marine  animals.  Along  our  coast  this  submergence 
exceeded  one  hundred  feet.  The  proof  of  this  statement  will  be  given 
under  the  head  of  Surface  Geology.  The  St.  Lawrence  valley  has 
yielded  marine  shells  at  the  height  of  470  feet  at  Montreal,  and  at 
somewhat  lower  elevations  in  Ontario.  When  the  St.  Lawrence  valley 
was  thus  covered  by  salt  water,  the  maritime  plants  would  naturally 
creep  along  the  shore ;  and  thus  may  be  explained  with  certainty  their 
introduction  as  far  as  the  basin  of  Lake  Ontario.  So  far,  the  explana 
tion  must  be  satisfactory,  especially  since  no  conclusions  are  involved 
that  cannot  be  legitimately  drawn  from  other  sources. 

If  the  theory  is  valid,  it  may  be  used  to  account  for  the  introduction 
of  maritime  plants  along  Lakes  Erie,  Michigan,  Huron,  and  Superior, 
and  it  is  difficult  otherwise  to  understand  how  they  could  have  made 
their  appearance  in  Minnesota.  But  Lake  Superior  is  surrounded  by 
terraces  up  to  330  feet,  or  968  feet  above  the  ocean.  It  is  agreed  that 
these  terraces  indicate  former  levels  of  water;  and  that  the  period  of 
submergence  was  essentially  coeval  with  that  of  depression  along  the 
sea  border  indicated  by  the  fossils.  The  inference  therefore  seems 
legitimate  that  these  high  terraces  were  formed  beneath  the  salt  water 
which  introduced  the  plants.  If  so,  an  argument  is  afforded  of  a  sub 
mergence  of  the  land  about  the  great  lakes  of  about  one  thousand  feet. 
Fossil  shells  of  the  Champlain  age  have  been  found  at  the  height  of 
1000  feet,  on  Cornwallis  and  Beechey  islands  in  Arctic  America;  and  it 
may  be  that  the  depression  of  the  land  was  uniform  over  all  the  northern 
part  of  our  continent  at  this  time.  But  at  present  the  arguments  from 
the  distribution  of  the  maritime  plants  and  the  supposed  requirements 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       567 

of  the  terraces  are  all  that  can  be  relied  upon  to  suggest  so  great  a 
submergence. 

From  molluscan  remains  it  is  proved  that  the  Hudson  and  Champlain 
valleys  were  covered  by  salt  water  in  the  period  now  under  consideration. 
The  proof  of  submergence,  from  the  occurrence  of  maritime  plants,  is 
very  meagre,  only  four  species  appearing  on  the  list.  It  is  possible  that 
future  researches  may  add  to  the  list,  though  not  in  large  numbers,  after 
the  researches  of  Oakes,  Tuckerman,  Torrey,  Zadock  Thompson,  and 
Peck.  It  may  likewise  be  observed  that  the  lower  St.  Lawrence  fur 
nishes  fewer  species  than  the  borders  of  the  great  lakes.  These  defi 
ciencies  were  so  patent,  that  Mr.  Peck,  in  his  reply  to  my  inquiries, 
regarded  "the  connection  between  the  maritime  plants  of  the  region  of 
the  great  lakes  with  the  Atlantic  ocean,  by  intermediate  stations,  as  not 
well  shown."  Is  it  not  possible  that  these  breaks  in  the  connection  are 
proofs  of  the  correctness  of  our  theory  ?  If  the  continued  existence  of 
these  plants  about  the  lakes  is  due  to  the  presence  of  large  bodies  of 
water,  even  in  the  absence  of  salt,  then  we  should  not  expect  to  find 
them  remaining  along  the  narrow  Champlain,  nor  the  still  narrower 
Hudson  river,  nor,  to  a  large  extent,  the  St.  Lawrence.  The  conditions 
are  not  favorable  to  their  preservation.  Furthermore,  if  the  species  were 
equally  distributed  from  the  ocean  into  the  interior,  or  especially  if  they 
became  fewer  in  number  the  farther  they  penetrated  the  continent,  it 
might  be  said  that  they  had  migrated,  since  the  Champlain  period,  even 
to  Minnesota.  Hence  what  might  appear  destructive  of  our  theory  is 
in  reality  a  strong  argument  in  its  favor.  These  considerations  were 
forcibly  set  forth  in  a  private  communication  from  Dr.  Ward. 

It  might  be  said  by  some  that  the  plants  in  the  salt  regions  of  western 
New  York  existed  there  naturally  on  account  of  the  presence  of  saline 
matters  in  the  soil.  This  circumstance  will  not,  however,  explain  their 
origin.  During  the  glacial  period  all  life  was  destroyed  by  the  intense 
cold.  Hence  the  salt-loving  plants  disappeared.  With  the  return  of 
the  warm  temperature,  the  plants  could  not  return  by  an  overland  emi 
gration.  They  could  return  only  by  a  gradual  migration  along  a  shore 
line,  whether  salt  or  fresh,  unless  it  be  supposed  plants  were  created  for 
this  special  locality.  The  latter  supposition  is  untenable,  since  a  special 
creation  is  not  required  to  explain  the  distribution  of  the  other  plants  in 


$68  PHYSICAL   GEOGRAPHY. 

the  Northern  states ;  and  we  cannot  suppose  there  would  be  any  differ 
ence  in  the  manner  of  the  introduction  of  the  two  classes.  Once  intro 
duced,  the  salt-loving  plants  would  find  a  congenial  habitat,  and  would 
not  disappear,  even  after  the  removal  of  the  estuary. 

There  is  hardly  a  possibility  that  the  seeds  of  these  plants  could  have 
been  preserved  in  the  ground  during  the  long  ages  of  glacial  cold,  and 
revivified  after  the  return  of  warmth.  Besides,  the  glacier,  in  plowing 
out  the  valleys,  would  have  transported  these  seeds  far  to  the  south,  and 
fresh  debris  from  the  north  would  have  covered  up  the  briny  exudations. 

Botanists  have  described  many  maritime  plants  from  the  salt  regions 
of  the  Rocky  Mountains.  These  are  the  descendants  of  those  which 
were  introduced  by  oceanic  migrations  in  Cretaceous  or  Tertiary  times ; 
and,  as  the  glacier  never  covered  them,  they  have  continued  uninter 
ruptedly  till  now. 

The  distribution  of  certain  forms  of  animal  life  confirms  our  theory. 
A  species  of  marine  crustacean  has  been  found  recently  by  Dr.  William 
Stimpson,  by  dredging  in  the  waters  of  Lake  Michigan.  Girard  de 
scribes  a  fish  from  these  northern  lakes,  Triglopsis  Thompsoni,  all  whose 
affinities  are  marine.  Add  to  these  the  oft-quoted  instance  of  marine 
insects  found  on  Lake  Superior  by  Dr.  Leconte,  and  a  parallel  case  of 
the  discovery  of  two  species  of  Mysis  in  Norwegian  lakes.  Also,  accord 
ing  to  F.  W.  Putnam,  director  of  the  Peabody  Museum,  in  Salem,  Mass., 
the  fishes  found  in  Lakes  Champlain  and  Erie  are  so  much  alike,  though 
widely  separated,  that  an  ancient  salt-water  connection  is  needed  to 
explain  their  present  isolation. 

Perhaps  other  evidences  of  a  marine  connection  may  be  found  in  Lake 
Winnipiseogee.  The  fishermen  are  now  familiar  with  a  fresh-water  smelt 
there,  which  is  said  to  be  the  same  species  with  the  one  so  abundant  in 
the  ocean.  This  fact  is  certainly  suggestive  of  a  former  connection 
between  the  lake  and  ocean. 

THE  WHITE  MOUNTAIN  PLANTS. 

Concerning  these  I  will  present  a  few  statements  prepared  by  Dr.  Na 
than  Barrows,  of  Meriden,  at  my  request,  and  read  before  the  Dartmouth 
Scientific  Association,  September  28,  1870. 

The  most  interesting  part  of  the  botany  of  New  Hampshire  is  that 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       569 

of  the  White  Mountains ;  and  on  our  alpine  summits,  above  the  limit  of 
trees,  the  vegetation  is  altogether  peculiar. 

About  fifty-four  plants  are  met  with  on  the  alpine  summits  of  the 
White  Mountains,  which  are  found  nowhere  else  in  New  England  except 
on  similar  summits  in  neighboring  states,  and,  in  addition  to  these,  prob 
ably  enough  species  whose  habitat  is  lower  down  find  their  way  to  the 
same  region  to  make  the  number  more  than  one  hundred.  On  my 
recent  visit  to  Mt.  Washington  and  its  neighbors,  I  made  what  obser 
vations  on  this  subject  my  limited  time  allowed,  noticing  fifty-eight 
such  species.  These,  added  to  the  fifty-four  truly  alpine  species,  make 
one  hundred  and  twelve  species  which  I  now  know  to  be  found  above  the 
limit  of  trees. 

An  enumeration  of  both  divisions  will  be  found  appended.  A  thor 
ough  investigation  of  this  subject  would  be  of  great  practical  value  ;  and 
perhaps  it  has  been  made,  though  not  within  my  knowledge. 

Of  these  plants,  at  least  thirteen  species  belong  to  the  Ericaceae,  eleven 
to  the  Compositas,  seven  to  the  Rosaceae,  four  to  the  Caryophyllaceae, 
three  each  to  the  Scrophulariaceas  and  Polygonaceae ;  while  there  are  two 
birches,  four  willows,  five  rushes,  thirteen  sedges,  and  two  club-mosses. 

On  the  very  summit  of  Mt.  Washington  are  found  in  comparative 
abundance  Arenaria  Grcenlandica,  Poa  laxa,  Juncus  trifidus,  and,  where 
there  is  a  little  moisture,  Carex  rigida, 

A  little  lower  down,  while  descending  the  first  steep,  rocky  sides  of 
the  highest  peak,  we  begin  to  find  in  dry  places  Potentilla  trifida,  the 
two  Lycopodia,  Diapcnsia  Lapponica;  and,  wherever  there  is  a  little 
more  warmth  and  moisture,  especially  on  the  slope  towards  Tuckerman's 
ravine,  the  Solidago,  some  of  the  grasses,  the  dwarf  Cornus,  chickweed 
wintergreen,  June  us  filifonnis,  and  a  variety  of  the  Carex  cancscens, 
which  grows  abundantly  throughout  New  Hampshire.  We  then  begin 
to  find  the  great  variety  of  Alpine  shrubs,  most  of  which  get  along  with 
out  much  moisture,  but  where  there  is  a  moist  spot,  the  Painted  cup, 
Peck's  Geum,  the  two  species  of  Nabalus,  and  Spircea  salicifolia. 

I  found  both  the  common  sorrel  (Rumex  acctosella)  and  herds-grass 
(Plileum  pratense)  far  up  toward  the  summit. 

Around  the  Lake  of  the  Clouds  may  be  found  the  willows  and  alpine 
birch,  the  alpine  violet  and  bistort  and  cranberry,  Linncsa  borealis,  the

common  harebell,  and  many  of  those  species  which  have  already  been 
mentioned ;  while  at  the  head  of  Tuckerman's  and  other  ravines  we  see 
the  Arnica,  Epilobium,  Veronica,  the  grasses,  willows,  and  alder;  and,  in 
certain  limited  localities,  rare  and  local  plants  like  the  Gnaphaliiun,  Car- 
daminc,  EupJirasia,  Rhinanthus,  and  O.vyria. 

I  have  aimed  to  give  only  a  general  idea  of  the  manner  in  which  plants 
are  distributed  on  this  one  alpine  summit,  as  my  knowledge  of  the  sub 
ject  is  too  limited  to  attempt  a  thorough  statement  of  localities.  The 
whole  mountain  region  of  New  Hampshire  ought  to  be  thoroughly 
studied  with  reference  to  the  determination  of  the  limits  of  species.  A 
thorough  botanical  exploration  of  one  such  mountain  as  Washington, 
from  base  to  summit,  including  an  examination  of  every  spur  and  ridge 
and  ravine,  would  do  more  to  advance  botanical  science  and  determine 
those  influences  which  fix  the  limits  of  species  than  the  same  amount  of 
time  and  labor  expended  in  any  other  way.  Moreover,  there  are  portions 
of  this  region,  as,  for  instance,  Mt.  Carrigain  and  its  vicinity,  which  seem 
to  have  received  as  yet  almost  no  attention ;  and  I  feel  sure  that  in  these 
solitudes  many  anxious  plants  still  await  names  from  their  fortunate 
discoverer. 

There  are  certain  marked  peculiarities  of  these  alpine  plants  which  are 
worthy  of  notice.  First,  they  are  all  perennials,  with  the  single  excep 
tion  of  EupJirasia  officinalis,  and  this,  according  to  Tuckerman,  is  found 
only  about  the  head  of  Oakes's  gulf,  quite  far  from  the  summit  of  Mt. 
Washington.  Second,  the  size  of  individual  flowers  is  in  general  remark 
ably  large  for  the  genus.  We  have  thirty-nine  species  of  Solidago.  The 
S.  Virga-aurca, — var.  alpina, — is  the  largest  of  them  all;  and  the  next  in 
size  is  5.  thyrsoidca,  which  runs  up  as  far  as  the  Lake  of  the  Clouds. 
These  are  the  only  ones  found  upon  the  summit.  Peck's  Gcum  has  the 
largest  flower  of  all  the  nine  species  of  that  genus.  The  flower  of 
Nabalus  Boottii  is  the  largest  in  the  nine  species  of  that  genus.  The 
Arnica  mollis  is  a  large  flower;  Poa  laxa  is  the  largest  flowered  of  our 
thirteen  Pocz;  and  the  same  thing  may  be  remarked  of  many  of  the 
ericaceous  shrubs. 

Another  thing  worthy  of  notice  is  the  manner  of  growth  of  the  alpine 
shrubs.  Most  of  them,  after  rising  a  few  inches,  spread  out  abruptly, 
adapting  themselves  to  the  surface  of  any  rock  which  may  be  near,  thus 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       5/1 

giving  them  support  and  warmth,  and  power  to  resist  the  fierce  winds 
which  frequent  these  regions.  Even  the  firs  at  the  heads  of  the  ravines 
do  the  same  thing,  and,  sometimes,  where  they  grow  thick  together,  after 
rising  two  or  three  feet  above  the  rocks,  they  spread  out  with  a  flat  sur 
face,  following  the  general  slope  of  the  ravine,  and  become  so  thickly  in 
terwoven  that  one  with  care  may  walk  quite  a  distance  on  their  surface, 
as  upon  a  lawn, — yet  if  he  do  chance  to  slip  through  a  treacherous  open 
ing  into  the  apartments  beneath,  if  will  be  some  time, — if  not  longer,  as 
I  have  found  to  my  cost, — before  he  gets  out  again. 

Another  point  of  great  interest  in  the  study  of  our  mountain  flora  is 
the  large  ratio  of  species  common  to  it  and  Europe.  Confining  our 
inquiries  to  the  strictly  alpine  plants,  forty-two  of  fifty-three,  or  sev 
enty-nine  per  cent.,  are  common  to  both  countries.  This  fact  lends 
countenance  to  the  hypothesis  that  the  two  countries  were  formerly 
much  more  intimately  connected  by  means  of  a  mountain  chain  than 
they  are  at  present.  I  am  not  aware  what  the  ratio  of  species  common 
to  the  European  and  American  floras  as  a  whole  is,  but,  remembering 
that  in  the  inquiry  we  must  confine  ourselves  to  indigenous  plants  exclu 
sively,  it  must  be  much  less  than  twenty  per  cent.  The  disparity  is  from 
any  point  of  view  quite  remarkable,  and  its  cause  worthy  close  investi 
gation.

The  species  marked  with  the  letter  M  in  the  catalogue  are  only  those

themselves  upwards  in  favorable  seasons,  and  are  naturalized  there  to  a 
certain  extent.  We  present  a  list  of  those  that  have  been  gathered  upon 
Mt.  Washington,  mostly  in  the  sub-alpine  district.  They  are  also  marked

REMARKS.  A  careful  comparison  of  the  names  of  plants  assigned  to  the  two  alpine 
districts  in  the  lists  above  with  those  in  the  catalogue  (Chapter  XIII),  shows  that  they 
do  not  harmonize  perfectly.  Different  observers,  without  an  opportunity  for  comparing 
notes  and  specimens,  cannot  be  expected  to  agree  in  every  minute  particular ;  and  Dr. 
Barrows  and  Mr.  Flint  have  had  no  opportunity  for  interchanging  their  views.  Each 
one  mentions  two  or  three  species  not  given  by  the  other.  They  do  not  enter  upon 
the  question  of  separating  the  alpine  from  the  sub-alpine  species.  I  commenced  an 
investigation,  hoping  to  be  able  to  find  distinctions  in  the  distribution  of  these  plants 
which  might  correspond  with  those  among  the  insects  mentioned  by  Mr.  Scudder  (p. 
336),  but  have  been  doomed  to  disappointment.  Prof.  Gray's  opinions,  as  held  in 
1856,  are  indicated,  but  these  do  not  agree  with  those  proposed  by  other  eminent 
botanists  with  whom  I  have  been  in  correspondence.  These  two  districts  are  so  near 
each  other,  and  so  limited  in  extent,  that  the  climatic  conditions  are  very  nearly  the 
same.  Hence  the  species  may  have  emigrated  from  their  original  limits,  both  upwards 
and  downwards,  so  that  the  boundary  line  cannot  be  drawn.  Another  cause  of  inter 
mingling  may  have  been  the  climatic  fluctuation  intimated  by  the  former  occupation 
of  the  Canadian  region  by  the  Alleghanian  forms  up  to  the  base  of  the  mountains 

(P-'S43)- 

As  the  evidence  from  the  plants  themselves  is  obscure,  I  think  we  may  be  warranted, 
in  the  further  study  of  this  subject,  to  assume  as  correct  the  insectean  bounds  given  on 
Plate  C,  Chapter  XII.  Then  notes  should  be  taken  of  the  distribution  of  all  the  plants 
above  the  line  of  trees.  Should  the  facts  thus  gained  not  arrange  themselves  satis 
factorily,  the  only  other  course  is  to  study  the  distribution  of  the  same  species  about 
Hudson's  bay,  Greenland,  and  other  alpine  districts,  ascertain  the  denizens  of  the  two 
zones  in  typical  localities,  and  then  assign  to  each  group  those  of  the  White  Mountain 
plants  that  are  represented  farther  north.  When  we  find  fifty-eight  species  of  Cana-

dian  plants  climbing  into  the  alpine  district,  it  is  not  strange  that  the  smaller  number 
of  boreal  species  should  in  like  manner  spread  themselves  even  into  Alleghanian 
townships. 

THE  BOUNDARY  BETWEEN  THE  ALLEGHANIAN  AND  CANADIAN  DIS 
TRICTS. 

In  order  to  show  the  near  correspondence  of  the  dividing  line  between 
the  Alleghanian  and  Canadian  districts,  according  to  the  several  methods 
of  distinction  that  have  been  suggested,  I  annex  a  map  showing  the 
course  of  the  following  lines,  first, — the  broad  band  settled  upon  by  Mr. 
Scudder  as  separating  the  insects  of  the  two  faunae ;  second,  the  upper 
line  of  the  white  oak ;  third,  the  approximate  contour  line  of  six  hun 
dred  feet  elevation ;  fourth,  the  isothermal  line  of  fifty  degrees  for  April, 
May,  and  June.  It  will  be  seen,  by  referring  to  the  map  showing  the 
distribution  of  forest  trees,  that  the  chestnut  limit  does  not  fall  much 
behind  that  of  the  white  oak,  the  whole  area  occupied  by  it  being  colored. 

The  upper  limit  of  the  white  oak  extends  above  the  six-hundred-feet 
contour  line  as  far  as  Plymouth,  from  the  south  line  of  the  state ;  may 
agree  with  it  for  a  few  miles  in  the  lake  region,  but  extends  farther  north 
in  the  Pemigewasset  and  Saco  valleys.  In  the  lower  part  of  Carroll 
county  there  is  an  area  above  six  hundred  feet.  I  do  not  think  the  facts 
are  known  with  sufficient  precision  to  state  the  presence  or  absence  of 
the  oak  in  this  area.  There  are  other  limited  areas  of  greater  height 
not  indicated,  as  the  Gunstock  region,  where  the  oak  certainly  does  not 
flourish.  Along  the  Connecticut  the  limit  of  the  oak  reaches  as  far 
as  the  contour  line ;  while  in  the  south-west  part  of  Cheshire  county  the 
reverse  is  true.  Were  it  legitimate  to  strike  an  average  in  this  case,  it 
could  truly  be  said  that  the  two  lines  correspond  very  well.  There  may 
be  special  reasons  in  every  case  of  variation  for  the  spread  of  the  tree 
beyond  or  within  the  limits  of  the  contour,  derived  from  the  character 
of  the  soil  or  particular  topographical  features,  which  might  be  discov 
ered  upon  investigation.  Somewhat  similar  variations  appear  upon  ex 
amining  the  isothermal  line  of  fifty  degrees  for  the  three  months  of 
April,  May,  and  June,  proposed  by  Prof.  Verrill  as  the  limit  between  the 
Canadian  and  Alleghanian  birds.  This  line  runs  up  to  Berlin  on  the 
Androscoggin,  may  touch  Jackson  and  Bartlett  on  the  Saco,  curving 
round  the  southern  White  Mountains  to  pass  up  to  Thornton  and  War-

ren,  and,  probably,  to  connect  with  the  line  passing  up  from  White  River 
Junction  to  Northumberland.  Returning  southerly  from  the  south  line 
of  Stratford,  it  curves  up  the  Passumpsic  south  of  the  Concord  (Vt.)  hills 
an  unknown  distance.  From  thence  it  would  naturally  follow  back  the 
Connecticut,  on  the  west  side,  to  ascend  the  White  River  valley.  I 
think  it  must  reach  Craftsbury,  Vt.,  from  the  White  river,  rather  than 
the  Passumpsic  valley,  this  being  a  point  on  the  line  specially  men- 
toned  by  Prof.  Verrill. 

From  the  facts  already  presented,  one  would  infer  that  the  six-hun 
dred-feet  contour  line  and  the  upper  limit  of  the  white  oak  approach 
nearer  to  the  limits  of  the  insect  faunas,  as  given  by  Mr.  Scudder,  than 
the  isothermal  of  fifty  degrees.  Two  considerations,  however,  are  im 
portant  in  this  connection : — First,  the  distribution  of  the  insects,  birds, 
and  trees  may  not  coincide  perfectly  with  one  another.  There  is  no  law 
of  nature  providing  that  these  areas  should  coincide  with  mathematical 
exactness.  Second,  these  different  lines  have  been  drawn  only  approxi 
mately.  When  the  temperature,  altitude,  and  exact  limits  of  all  the 
birds,  insects,  and  trees  shall  have  been  studied  with  special  reference  to 
the  determination  of  this  point,  a  closer  correspondence  may  be  discov 
ered.  I  have  gone  as  far  as  possible  without  making  special  explorations, 
using  only  what  has  been  picked  up  incidentally.  It  would  be  of  much 
importance  to  the  agricultural  interests  of  the  state  if  such  investiga 
tions  could  be  pursued  farther,  since  the  accurate  determination  of  this 
line  shows  the  proper  limits  of  the  cultivation  of  the  grape,  cranberry, 
and  the  choicer  fruits.  Their  cultivation  is  not  now  carried  so  far 
north  as  nature  allows. 

EXTENT  OF  FOREST. 

'  It  is  often  important  to  know  how  extensive  the  wood-growth  of  a 
country  is;  and,  in  order  to  illustrate  this  subject  as  far  as  possible,  I 
have  appended  a  small  colored  map  showing  the  areas  occupied  by  trees 
at  the  present  time  in  New  Hampshire,  and  a  short  distance  into  the 
surrounding  territory.  It  is  supposed  the  whole  of  the  state  was  origi 
nally  covered  by  the  forest.  The  white  parts  of  the  map  show  how 
much  has  been  cleared,  and  in  what  neighborhoods  settlements  have 
sprung  up.  The  first  glance  at  the  map  shows  where  the  woodman's 


5/6  PHYSICAL    GEOGRAPHY. 

axe  has  not  yet  penetrated,  save  for  the  purpose  of  cutting  lumber.  This 
dense  forest  occupies  most  of  Essex  county,  Vt,  the  adjacent  townships 
of  Quebec,  and  nearly  twenty  townships  at  the  north-west  angle  of 
Maine.  I  have  tried  to  represent  all  the  forest  in  Maine  to  the  north 
west  of  a  line  from  Conway  to  the  south  part  of  Weld. 

Several  points  deserve  mention: — First,  I  have  separated  by  another 
color  the  tops  of  the  mountains  which  are  above  trees.  As  some  may 
object  to  the  correctness  of  this  representation,  I  will  explain.  The 
largest  alpine  area,  or  region  above  trees,  is  coincident  with  the  summits 
of  the  Mt.  Washington  range.  It  is  given  on  a  larger  scale  in  Chapter 
XII,  Plate  C.  Of  the  other  White  Mountain  areas,  Mts.  Lafayette, 
Profile,  Moosilauke,  and  Twin  are  certainly  devoid  of  trees  upon  their 
summits.  Of  the  others,  Mts.  Willey,  Crawford,  Mote,  Pequawket, 
Chocorua,  Osceola,  Black,  and  Carter,  with  others  not  represented,  are 
bare  now,  but  may  have  been  covered  by  a  stunted  growth  originally. 
Possibly  the  Pilot  and  Starr  King  mountains,  with  the  Stratford  peaks, 
may  belong  to  the  same  category.  Certainly,  Kearsarge,  Gunstock, 
Sunapee,  and  Monadnock  must  be  placed  among  those  which  once 
supported  a  stunted  growth.  In  the  clearing  of  the  country,  many  of 
these  summits  became  involved  in  the  merciless  destruction  of  the  trees, 
and  nature  has  not  been  able  to  rehabilitate  them. 

Second,  oftentimes  the  trees  are  retained  because  they  grow  upon 
mountains  or  high  hills.  Such  is  commonly  the  case  all  over  the  White 
Mountains,  much  of  Coos  and  Essex  (Vt.)  counties,  the  quartzite  range 
from  Piermont  to  Claremont,  Red  hill,  Ossipee,  Green  mountain  in 
Effingham,  the  Gunstock  region,  Moose  mountain  district,  between 
Carroll  and  Strafford  counties,  Saddleback  in  Northwood,  McKoy's 
and  Fort  mountain  in  Epsom,  range  from  New  Ipswich  to  New  Boston, 
Uncanoonucs,  large  areas  along  the  Connecticut-Merrimack  ridge,  hills 
in  the  south-west  part  of  Cheshire  county,  etc.  Third,  for  a  similar 
reason,  one  can  pick  out  woodland  areas  upon  the  county  maps  from 
tracts  of  land  not  traversed  by  roads.  Some  of  the  county  maps,  as 
that  of  Cheshire,  take  pains  to  point  out  where  forests  are  situated,  by 
appropriate  markings.  Fourth,  the  forest  trees  are  disappearing  rapidly 
in  some  sections,  and  gaining  in  others.  The  presence  of  a  new  railroad 
is  the  sure  precursor  of  the  disappearance  of  the  forest.  I  have  noticed 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       577 

this  fact  in  a  marked  degree  along  the  Manchester  &  Portsmouth  Rail 
road,  in  Auburn,  Candia,  and  Raymond.  The  prospective  opening  of  the 
Portland  &  Ogdensburg  Railroad  will  soon  witness  the  stripping  of  the 
forests  between  Whitefield  and  Conway.  In  the  older  and  higher  towns, 
between  the  Connecticut  and  Merrimack  rivers,  the  trees  are  gaining. 
Hundreds  of  farms,  showing  the  names  of  their  owners  upon  the  maps 
of  twelve  to  fifteen  years'  issue,  exhibit  a  return  to  the  primitive  condi 
tion.  The  houses  are  deserted  or  pulled  down,  and  the  grass-land  is  full 
of  shrubs.  The  roads,  also,  in  many  localities,  have  been  abandoned,  and 
more  ought  to  be,  since  they  need  repair  so  badly. 

Nature  is  taking  the  proper  course  with  much  of  our  territory.  She 
points  out  more  desirable  localities  to  the  tillers  of  the  ground,  and,  when 
they  remove,  the  trees  spring  up  again.  It  appears,  from  observations 
upon  the  salutary  influences  of  forests,  that  a  certain  part  of  every  country 
must  be  kept  in  wood-growth,  in  order  to  preserve  the  balance  of  nature. 
It  is  supposed  that  forests  exert  an  influence  upon  the  amount  of  moist 
ure  precipitated;  and  it  is  certain  that  the  removal  of  the  trees  causes 
greater  freshets  after  rain-storms,  because  there  is  nothing  to  keep  the 
water  back.  With  abundant  vegetation  present,  moisture  is  absorbed, 
kept  back,  and  evaporation  is  retarded.  In  time,  legislation  will  require 
the  replanting  of  much  of  our  woodland,  unless  the  planting  of  shade- 
trees  abundantly  in  the  settled  districts,  and  the  emigration  of  much  of 
the  hill  population,  restore  the  balance  of  nature,  without  the  necessity 
of  intervention.  Legislation  may  judiciously  hasten  the  restoration  of 
forests  by  encouraging  the  planting  of  shade-trees ;  and  it  should  be  a 
part  of  the  duty  of  agricultural  associations  to  offer  premiums  for  the 
production  of  artificial  forests.  Experiments  in  forcing  the  growth  of 
timber  trees  may  also  be  encouraged. 

-  On  the  map  I  have  endeavored  tot  show  where  the  principal  patches 
occur.  We  might  estimate  by  percentages,  calling  the  original  universal 
growth  100,  and  the  average  approximation  to  it  in  a  township  by  the 
estimated  part  of  the  natural  abundance  now  existing.  But  I  have 
thought  it  easier  to  show  by  colors  essentially  the  position  and  rela 
tive  dimensions  of  the  present  wood-growth,  premising  that  the  cleared 
portions  are  more  likely  to  fall  short  of  than  to  exceed  the  representation. 

Some  very  valuable  facts  in  reference  to  the  extent  of  our  forests  are

given  in  the  answers  by  well  informed  persons  in  most  of  our  towns  to 
questions  put  by  James  O.  Adams,  secretary  of  the  Board  of  Agricul 
ture.  I  have  condensed  these  estimates  from  the  original  statements  in

tion  was  couched  in  the  following  language:  "What  proportion  of  the

SIZE  OF  FOREST  TREES. 

The  woodmen  are  so  ready  to  cut  down  the  largest  trees  in  the  forest, 
that  it  seems  proper  to  preserve  in  permanent  form  a  few  facts  that  have 
fallen  under  our  notice  respecting  the  size  of  the  larger  specimens,  of 
which  there  is  an  authentic  record. 

David  M'Clure  and  Elijah  Parish,  in  their  memoirs  of  President  Eleazer 
Wheelock,  of  Dartmouth  college,  state  that  it  was  common  a  hundred 
years  since  to  see  pine  trees  in  Hanover  over  200  feet  in  length.  One 
of  them  measured  a  pine  growing  within  the  academic  precincts,  and 
found  it  to  be  270  feet  long.  Some  of  the  present  officers  of  the  col 
lege  thought  these  dimensions  rather  large;  but  the  late  President 
Lord  came  across  the  ruins  of  an  old  pine  in  one  of  his  rambles,  and, 
by  pacing,  proved  the  length  of  it  to  be  230  feet. 

Dr.  Williams,  of  Vermont,  states  the  height  of  the  pine  to  be  247 
feet.  Zadock  Thompson  has  seen  them  170  feet  long,  and  measuring 
about  6  feet  on  the  stump.  He  also  says  the  larch  attains  the  height 
of  100  feet,  with  a  diameter  of  about  2  feet. 

The  following  notices  of  large  trees  I  have  obtained  from  items  in  the 
Independent  Statesman,  during  the  past  four  years,  and  presume  the 
figures  are  essentially  correct. 

Granville  Felton  cut,  on  the  farm  of  D.  W.  Trow  in  Amherst,  a  chestnut  tree  which 
measured  7  feet  in  diameter  at  the  butt. 


58O  PHYSICAL    GEOGRAPHY. 

William  Patterson  obtained  a  chestnut  log  in  South  Merrimack,  54  feet  long,  17 
inches  through  at  the  top,  5  feet  8  inches  at  the  butt,  containing  174  feet  of  lumber, 
board  measure. 

Schuyler  Aldrich,  of  Great  Falls,  cut  an  elm  tree  measuring  4  feet  8  inches  in  diam 
eter  at  the  butt,  and  3  feet  8  inches  40  feet  higher  up.  At  this  point  two  limbs 
branched  off,  each  2  feet  in  diameter. 

Near  the  Concord  Railroad  in  Greenland,  there  stands  an  elm  which  measures  27 
feet  in  circumference  6  feet  above  the  ground. 

James  Thatcher,  of  Moultonborough,  cut  a  hemlock  belonging  to  George  Thatcher, 
which  measured  90  feet  in  length.  It  seemed  to  have  290  rings  of  growth. 

Andrew  Farnuin,  of  West  Concord,  cut  a  red  oak,  being  5  feet  in  diameter  at  the 
butt,  the  log  weighing  over  3  tons. 

S.  W.  Vose,  of  Peterborough,  cut  a  maple  3  feet  in  diameter,  with  370  rings  of 
growth. 

W.  S.  Marston,  of  East  Anclover,  cut  4!  cords  of  wood  from  a  pasture  maple. 

The  Messrs.  Mclntire,  of  Littleton,  recently  cut  a  spruce  tree  on  Palmer  brook, 
measuring  130  feet  in  height,  and  16  inches  in  diameter  65  feet  from  the  ground. 

Amon  Lord,  locality  not  stated,  cut  a  pine  5  feet  in  diameter  at  the  butt;  32  feet 
higher  it  was  4^  feet  through.  The  entire  tree  furnished  over  4000  feet  of  lumber. 

W.  K.  Quimby  has  a  pine  measuring  21  feet  in  circumference  at  the  base.  It  is  as 
straight  as  a  candle,  and  limbless  for  100  feet  above  the  ground.  It  is  estimated  to 
contain  7000  feet  of  sound  lumber. 

Two  pines  on  land  of  John  Batchelder,  of  Laconia,  scaled  3500  and  3000  feet  re 
spectively.  One  was  140  feet  long. 

W.  H.  F.  Staples,  of  Errol,  hauled  in  a  spruce  log  64  feet  long,  measuring  1130 
feet.  Mr.  Marden  cut  a  pine  on  the  College  grant,  measuring  54  inches  in  diameter  on 
the  stump.  The  butt  log,  28  feet  long,  scaled  5000  feet. 

Mayland  &  Woodman  cut  a  pine  on  the  Atkinson  Academy  grant,  which  scaled 
12,000  feet.  It  was  7  feet  4  inches  in  diameter  on  the  stump,  and  3  feet  i  inch  in 
diameter  90  feet  from  the  butt. 

Charles  Gray  cut  on  the  Parker  lot,  North  Charlestown,  a  pine  whose  stump  meas 
ured  5  feet  in  diameter.  The  logs  amounted  to  115  feet  in  length.  It  was  2^  feet  in 
diameter  44  feet  from  the  ground.  There  were  four  of  about  the  same  size. 


There  are  rive  enormous  elms  in  front  of  the  residence  of  Jos.  B.  Walker,  Concord, — 
transplanted  to  their  present  positions  no  years  since, — measuring,  at  the  height  of  3 
feet  from  the  ground,  in  1871,  from  9  feet  4  inches  to  16  feet  10  inches  in  circumfer 
ence.  In  fifteen  years  the  largest  one  increased  10  inches  in  girth.  Two  others, 
during  the  same  time,  increased  from  16  to  19  inches. 

In  Dr.  Bouton's  History  of  Concord,  it  is  stated  that  Lieut.  John  Walker  cut  a  pine 
in  Northfield  measuring  38  inches  in  diameter  60  feet  from  the  butt. 


REMARKS  UPON  THE  DISTRIBUTION  OF  ANIMALS  AND  PLANTS.     581 
THE  DESTRUCTION  AND  RENOVATION  OF  THE  FORESTS. 

BY   J.    H.    HUNTINGTON. 

At  the  time  of  the  advent  of  the  white  men,  the  whole  state,  except 
perhaps  some  small  areas  on  the  rich  alluviums  where  the  Indians  raised 
their  corn,  was  covered  with  a  dense  forest  from  the  sea-shore  almost  to 
the  summits  of  the  highest  mountains.  Along  the  streams  especially 
the  pines  assumed  gigantic  proportions;  but  now  those  suitable  for 
masts  are  found  only  in  the  deep  ravines  far  up  among  the  recesses  of 
the  mountains.  In  general,  the  deciduous  trees  were  found  on  the  fertile 
uplands,  while  the  swamps,  the  ravines,  and  less  fertile  uplands  were 
occupied  by  coniferous  trees, — the  spruce,  the  fir,  the  cedar,  and  the 
larch.  Where  there  was  nothing  except  boulders,  a  thin  bed  of  vege 
table  mould  formed  from  the  decay  of  moss  supported  only  a  growth 
of  fir. 

The  destruction  of  the  forests  by  the  axe  and  by  fire  is  becoming  a 
matter  of  serious  consideration.  In  clearing  land  for  cultivation,  the 
trees  when  cut  down  are  almost  invariably  burned,  and,  that  this  may  be 
effected  as  completely  as  possible,  the  driest  weather  is  frequently  se 
lected,  although  the  fire  is  much  more  likely  to  spread  into  the  surround 
ing  woods.  It  is  a  common  notion,  with  those  that  clear  land,  that  if 
they  get  a  "deep  burn"  they  will  secure  better  crops.  It  is  very  true  that 
better  crops  may  be  obtained  for  one  or  two  years,  but  after  that,  if  all 
the  vegetable  matter  was  burned,  the  land  will  be  almost  worthless  un 
less  the  vegetable  matter  is  restored.  Much  of  the  sterility  of  our  soil 
is  undoubtedly  due  to  this  cause.  In  our  forests  large  quantities  of  dry 
branches  and  tops  of  trees  are  left  by  lumbermen,  and  these,  when  dry, 
are-  exceedingly  imflammable.  Although  the  primitive  forests,  except 
near  the  summits  of  the  mountains,  are  rarely  subject  to  conflagrations, 
yet,  whenever  an  opening  is  made  through  which  the  sunlight  is  admitted, 
the  mossy  soil,  on  which  the  propagation  of  fires  largely  depends,  readily 
takes  fire.  In  fact,  the  fires  are  sometimes  confined  to  this  alone,  and, 
during  a  whole  summer,  the  fire  may  not  extend  over  more  than  an  acre 
of  ground.  In  such  cases  it  burns  up  entirely  the  vegetable  mould  from 
which  the  forest  trees  spring.  Here  and  there  a  tree  falls;  but,  in  the 


582 


PHYSICAL    GEOGRAPHY. 


first  gale  of  autumn,  the  trees  on  the  whole  burnt  area  are  prostrated, 
and  generally  in  the  greatest  confusion,  for  every  tree  is  torn  up  by  the 
roots,  and  seems  just  as  likely  to  fall  one  way  as  another.  There  was  an 
instance  of  this  kind  of  burning  in  the  summer  of  1871,  about  two  miles 
north  of  the  Glen  house,  between  the  river  and  the  road ;  also,  the  same 
season,  on  the  mountain  south  of  West  Milan,  and  the  fire  was  not  put 
out  until  after  the  snow  came.  On  the  summits  of  the  mountains, 
where  there  is  nothing  scarcely  except  lichens  and  sedges,  if  a  fire  is 
kindled  in  these  when  they  are  dry,  which  is  a  thing  quite  uncommon,  it 
sweeps  across  the  mountains  with  incredible  rapidity ;  and  the  roaring  of 
the  flames  can  be  heard  for  miles,  when  they  reach  the  stunted  growth 
of  the  spruce  and  the  fir.  On  a  mountain  of  moderate  elevation  in  North 
Stratford,  it  is  said  that  the  lightning  set  the  woods  on  fire ;  but  such 
cases  must  be  extremely  rare.  When  the  fire,  instead  of  being  confined

to  the  ground,  runs  up  the  white  birch,  the  bark  of  which  is  so  inflam 
mable,  it  catches  in  the  branches  of  the  coniferous  trees,  and  streams 
far  above  their  summits  in  columns  and  streamers  of  lurid  flame ;  the 
wind  carries  pieces  of  lighted  wood  across  the  widest  streams ;  and  the 


REMARKS    UPON    THE    DISTRIBUTION    OF    ANIMALS    AND    PLANTS.       583 

progress  of  the  flames  continues  sometimes  until  hundreds  of  square 
acres  are  devastated. 

'  When  the  fire  has  run  through  a  forest,  if  it  is  a  hard-wood  growth, 
there  are  often  some  trees  that  escape  its  ravages ;  but  the  paper  birch 
very  rarely  survives  a  forest  fire.  Persons,  travelling  through  our  primi 
tive  forests,  frequently  set  the  bark  of  the  birch  on  fire  to  see  it  burn ; 
and  fire  from  these  is  communicated  to  other  trees,  and  large  areas  of 
forest  are  consumed.  When  the  woods  consist  of  dark  growth  or  con 
iferous  trees,  the  fire  not  only  kills  the  trees,  which  are  left  to  furnish 
fuel  for  a  second  conflagration,  but  it  is  also  communicated  to  the  ground, 
and  a  large  part  of  the  vegetable  substance  of  the  soil  is  consumed.  The 
trees  fall  with  the  first  wind,  and  the  fire  of  another  year  leaves  not  a 
trace  of  vegetable  matter  on  or  in  the  soil.  Mote  mountain  is  a  notable 
instance  of  this,  for  here,  over  large  areas,  there  is  not  a  vestige  of  any 
thing  vegetable. 

It  would  be  interesting  to  trace  the  way  in  which  the  restoration  of 
our  forests  is  effected,  but  we  can  only  indicate  some  of  the  methods. 
In  our  northern  forests,  if  only  those  trees  are  removed  that  are  useful 
for  lumber,  and  the  land  is  not  burned,  the  same  description  of  wood  is 
immediately  reproduced.  In  most  of  our  primitive  forests  there  are 
very  many  young  trees,  from  mere  saplings  to  those  almost  ready  for 
the  axe  of  the  lumberman.  These  now  having  the  sunlight,  with  those 
produced  from  seed,  soon  take  the  place  of  those  removed.  In  the 
southern  part  of  the  state  the  stumps  of  the  deciduous  trees  produce 
shoots,  and  soon,  over  the  whole  area  where  the  trees  have  been  re 
moved,  there  is  a  vigorous  growth  from  this  source  alone.  In  the 
northern  part  of  the  state  this  mode  of  reproduction  is  exceedingly 
rare.  In  most  cases,  if  the  entire  growth,  including  the  underbrush, 
is  removed,  a  different  growth  from  that  which  occupied  the  soil  will 
succeed; — along  the  northern  boundary  we  have  an  illustration  of  this. 
Where  the  trees  are  burned,  and  only  a  part  of  the  vegetable  substance 
of  the  soil  is  consumed,  the  first  year  there  is  a  luxurious  growth  of 
herbs.  The  Epilobium,  known  as  the  fire-weed,  will  probably  be  the 
first  to  take  possession  of  the  soil ;  and  we  shall  be  likely  see  species  of 
the  Trillium,  the  tubers  of  which,  deep  in  the  soil,  have  escaped  the 
fire.  The  bunch-berry,  Cornus  Canadensisy  and  wintergreen,  GaultJieria

procumbens,  will  very  soon  find  places.  Of  shrubs,  the  cherry  will  be 
the  first;  but,  in  places  where  there  is  still  some  vegetable  substance 
left,  these  will  soon  be  succeeded  by  a  growth  of  poplar  and  white  birch. 
In  more  southern  latitudes,  the  shrubs  and  trees  that  spring  up  in  burnt 
districts  are  entirely  different. 

When  the  entire  vegetable  substance  of  the  soil  has  been  burned,  the 
process  by  which  the  woods  are  reproduced  is  long  and  complicated. 
Lichens  and  mosses  then  first  cover  the  ground,  and,  by  slow  degrees, 
flowering  plants  appear.  Among  the  first  shrubs,  especially  on  moun 
tains  and  on  sandy  plains,  there  will  be  some  species  of  the  blueberries. 
On  Percy  peaks,  where  years  ago  everything  except  the  rocks  was  con 
sumed  by  fire,  the  vegetation  can  now  be  seen  to  increase  year  by  year 
from  the  base  upward.  A  few  examples  will  show  the  contrast  which 
appears  between  the  primeval  forest  and  that  which  succeeds  it.  If  we 
ascend  Mt.  Washington  by  the  railway,  when  we  are  above  the  limit  of 
the  trees,  if  we  look  westward,  we  shall  see  that  in  the  valley  of  the 
Ammonoosuc  there  is  a  growth  of  deciduous  trees  that  extends  on 
either  side  far  up  the  side  of  the  mountain  ranges  that  border  the  val 
ley.  Some  forty  years  ago  a  destructive  fire  destroyed  the  primeval 
forest  of  spruce  and  fir ;  and  now  in  all  this  tract  the  principal  growth 
is  the  paper  birch.  Besides  this,  however,  there  is  the  yellow  birch,  and 
now  and  then  a  poplar ;  and,  as  a  new  growth,  we  find  the  original  occu 
pants  of  the  soil.  In  some  parts  of  the  town  of  Success,  the  only  growth 
now  is  poplar;  and  elsewhere  there  are  places  where  there  have  been 
so  many  successive  fires,  that  blueberries,  mosses,  and  lichens  are  the 
only  growth. 

The  bare  ridges  and  mountains  west  of  the  Saco  show  that  the  veg 
etable  matter  in  the  soil  even  has  been  consumed,  so  that  it  must  be 
many  years,  even  if  there  are  no  fires,  before  enough  will  accumulate, 
from  the  decay  of  lichens  and  mosses,  for  any  vegetation  whatever  to 
grow,  except  the  very  lowest  forms.  On  the  line  of  the  boundary  be 
tween  New  Hampshire  and  Quebec  province,  where  in  1845  tne  trees 
were  cut,  making  an  opening  in  the  forest  four  rods  wide  along  the  en 
tire  northern  boundary  of  the  state,  in  general,  where  there  was  a  hard 
wood  growth,  it  was  soon  reproduced,  but,  in  places  particularly  where 
there  was  a  growth  of  coniferous  trees,  the  cherry  at  first  predominated ;

elsewhere  the  swamp  or  mountain  maple  formed  such  a  thick  growth  as 
to  crowd  out  everything  else  for  a  time;  but  now  both  these  are  being- 
replaced  by  the  fir  and  the  spruce. 

It  might  seem  a  very  small  thing  at  first  that  the  mountain  tops  should 
be  bared,  the  slight  growth  of  vegetation  and  the  peat  being  consumed 
by  fire;  but  this  peaty  soil  holds  great  quantities  of  moisture  deposited 
from  the  passing  clouds,  and  of  rain  that  often  in  summer  is  poured 
down  in  such  floods  as  to  cause  terrible  havoc  along  the  mountain 
streams.  It  does  not  require  much  foresight  to  see  that,  if  half  of  this 
water  is  retained  on  the  mountain  summits  instead  of  being  poured  at 
once  into  the  ravines,  not  only  the  freshets  would  be  moderated,  but 
that  the  water  retained  would  be  evaporated  from  the  place  where  it  fell, 
instead  of  being  carried  by  the  rivers  into  the  sea;  and  thus  there  would 
be  a  more  equal  distribution  of  rain  in  the  vicinity  of  the  mountains,  and 
we  should  not  see  in  the  valleys  the  dry  and  parched  vegetation  which  is 
not  only  ruinous  to  the  farming  interests,  but  also  destroys  the  natural 
beauty  of  the  scenery.

CHAPTER     XVIII. 


SCENOGRAPHICAL      GEOLOGY. 

,HE  thousands  of  people  who  visit  the  White  Mountains  in  the 
summer  are  attracted  ostensibly  by  the  scenery.  They  climb  Mt. 
Washington  that  they  may  view  the  widest-spread  landscape  visible  from 
any  summit  in  America  east  of  the  Rocky  Mountains  and  north  of  Mt. 
Mitchell.  The  interest  attaching  to  the  crystal  cascades  and  the  pictur 
esque  Winnipiseogee  is  produced  by  a  different  element,  though  less 
fascinating  to  most.  From  North  Conway,  multitudes  watch  the  gor 
geous  colors  among  the  shifting  clouds,  when  the  sun  is  setting.  There 
are  also  other  features  that  render  the  Alps  of  America  attractive  to  the 
summer  resident. 

Considered  more  particularly,  the  following  are  the  principal  elements 
which  enter  into  landscapes :  first,  mountains,  hills,  valleys,  and  all  con 
figurations  of  the  surface;  second,  ledges;  third,  water,  whether  quiet  or 


SCENOGRAPHICAL    GEOLOGY.  587 

in  motion ;  fourth,  forests  and  vegetation  in  all  stages  of  being,  whether 
the  trees  clothed  in  verdure,  or  painted  brilliantly  as  the  leaf  is  about  to 
die,  or  the  diversely  colored  vegetation  of  swamps  and  alpine  regions; 
fifth,  the  effect  of  the  sky,  whether  clear,  or  variously  decked  with  clouds  ; 
sixth,  the  position  of  the  sun  and  moon,  perhaps  producing  shadows  or 
showy  prisms  of  color  to  brighten  the  scene.  To  consider  all  these  ele 
ments  would  be  inappropriate  for  this  volume ;  and  I  shall  chiefly  confine 
myself  to  the  first  one  mentioned,  and  point  out  several  of  the  ways  by 
which  the  shapes  of  our  mountains  and  hills  have  been  modified  by  geo 
logical  agencies.  I  have  given  a  large  number  of  views  of  landscapes  in 
the  volume,  and  will  describe  such  as  are  specially  pertinent.  At  the 
end  of  the  chapter  is  appended  a  list  of  the  sketches  given  in  this  report, 
which  illustrate  the  various  phases  of  the  subject.  Descriptions  of  the 
charms  of  sunset,  cloud  effects,  light  and  shade,  the  myriad  tints  of  veg 
etation,  the  varied  colors  of  the  hills,  and  the  brilliant  hues  of  autumn, 
need  not  be  looked  for.  Fortunately,  those  who  desire  to  read  such 
sketches  will  find  in  Starr  King's  WJiite  Hills  ample  treasures  of  this 
kind  of  word-painting. 

The  only  other  important  work  upon  the  scenery  of  the  White  Mountains  was  pre 
pared  by  William  Oakes,  of  Ipswich,  Mass.,  in  1848,  with  sixteen  folio  lithographs, 
after  drawings  by  Isaac  Sprague.  Only  a  few  copies  were  published,  and  very  few 
persons  have  seen  the  book.  Mr.  Oakes  was  an  eminent  botanist,  and  enthusiasti 
cally  interested  in  everything  pertaining  to  the  White  Mountains.  Except  for  the 
accident  which  closed  his  career,  he  would  have  done  much  more  for  our  scenery. 
First,  are  four  pages  of  text  devoted  to  a  general  notice  of  the  scenery ;  and  then 
each  plate  has  about  a  page  of  explanation  inserted  before  it.  Later  writers  have 
drawn  freely  upon  Oakes's  material.  There  are  heliotypes  in  this  report  correspond 
ing  to  nearly  every  one  of  these  drawings  of  Mr.  Sprague.  They  miss,  however,  the 
unusually  careful  copying  of  the  trees  and  plants  in  which  Oakes  was  so  well  versed. 
Many  of  our  alpine  plants  were  first  discovered,  and  now  bear  the  scientific  names 
imposed  by  him. 

The  following  are  the  subjects  of  Oakes's  volume : 

Plate  i.  The  White  Mountains,  from  the  Gianfs  grave,  in  front  of  the  present 
Fabyan  house.  Essentially  this  view  appears  in  Fig.  25,  and  in  the  heliotype  taken 
from  the  Fabyan  turnpike.  The  ravines  on  Mt.  Pleasant  and  towards  Washington  are 
delineated  with  great  truthfulness. 

Plate  2,  Mt.  Crawford,  with  the  Mt.  Crawford  house,  kept  by  Abel  Crawford,  in  the 
foreground.  This  is  the  same  with  our  view  having  Dr.  Bemis's  new  residence  in  the 
foreground . 


588  PHYSICAL    GEOGRAPHY. 

Plate  3.  Notch  of  the  White  Mountains,  with  the  Willey  house,  taken  from  the 
famous  slide.  This  is  the  same  with  our  small  heliotype  of  Alt.  Willard. 

Plate  4.     Silver  cascade.     This  accompanies  the  previous  heliotype. 

Plate  5.  Gate  of  the  Notch,  with  the  Notch  house.  This  is  reproduced  in  our 
view  from  the  Crawford  house,  save  that  no  vestige  of  the  Notch  house  is  now  left.  It 
was  situated  at  the  base  of  the  Elephant's  Head. 

Plate.  6.  Lower  falls  of  the  Ammonoosuc.  Preserved  only  as  a*  small  relief-plate 
illustration  in  the  next  volume. 

Plate  7.  Two  enlarged  views  of  the  cliffs  at  the  same  locality.  The  building  of  a 
saw-mill,  the  construction  of  a  heavy  railroad  embankment  alongside,  and  the  removal 
of  the  forests  have  taken  away  all  the  romance  pertaining  to  these  falls  in  Mr.  Oakes's 
day. 

Plate  8.  Franconia  notch,  taken  from  the  west.  We  have  a  small  heliotype  of  the 
same  cliffs  from  the  south,  which  seems  to  us  to  reproduce  the  spirit  of  the  mountains 
better  than  this  plate. 

Plate  9.     Profile  mountain.     Nothing  equal  to  this  appears  in  the  report. 

Plate  10.     The  Profile  rock.     Reproduced  in  Figs.  74  and  75. 

Plate  ii.     The  Basin.     Reproduced  in  a  heliotype. 

Plate  12.  The  Flume.  We  have  a  view  in  the  next  volume  of  the  great  boulder 
suspended  over  the  Flume.  This  lithograph  represents  the  whole  of  the  gorge,  also. 

Plate  13.     Nancy's  bridge. 

Plate  14.  Mt.  Crawford,  from  the  Notch,  and  view  in  the  opposite  direction  from 
the  top  of  Mt.  Crawford.  The  reproduction  of  the  first  appears  correctly  in  Fig.  26 
and  in  a  heliotype.  But  the  artists  have  exaggerated  the  shape  of  the  top  of  this 
mountain,  as  will  be  seen  by  comparing  Fig.  26  with  our  heliotype,  which  was  taken 
from  almost  the  same  spot. 

Plate  15.  White  Mountains,  from  Bethlehem;  Mt.  Washington,  from  the  summit 
of  Mt.  Pleasant;  diagram  of  the  whole  range  of  the  White  Mountains.  Only  the 
second  of  these  is  reproduced. 

Plate  16.  Mt.  Washington,  from  over  Tuckerman's  ravine.  This  is  essentially  the 
same  with  our  view  of  Mt.  Washington  from  the  south-east,  and  reveals  features  in  the 
structure  of  the  range  not  so  apparent  from  any  other  quarter. 

I  may  reasonably  take  the  ground  that  every  interesting  feature  of 
New  Hampshire  scenery  has  been  produced  by  geological  agencies.  In 
proof  of  this  proposition  I  would  refer  to  the  fact  of  the  existence  of 
mountains,  hills,  and  valleys.  Not  one  of  these  ever  came  up  out  of  the 
depths  without  the  aid  of  that  force  called  elevation.  Next,  the  present 
shape  of  every  ledge  or  mound  has  been  fashioned  by  some  excavating 
agent, — rill,  river,  glacier,  ocean  wave,  or  atmospheric  decomposition. 
Lakes  exist  because  permitted  by  the  rock-bound  barrier,  or  looser  earth, 


SCENOGRAPHICAL    GEOLOGY.  589 

liable  to  give  way,  and  precipitate  calamity  upon  the  valleys  beneath. 
Rivers  plunge  down  precipices,  giving  rise  to  cataracts  and  cascades. 
Vegetation  assumes  character  according  to  the  degree  of  elevation. 
Even  the  pure  skies,  the  gathering  of  mists  and  clouds,  depend  upon 
the  presence  of  the  elevated  ridges.  Hence  I  think  the  position  well 
established  that  geological  agencies  have  produced  all  the  charms  of 
landscape;  and,  were  we  so  disposed,  we  should  be  amply  justified  in 
describing  minutely  the  special  causes  of  change  that  have  fashioned 
every  foot  of  surface.  Those  who  would  thoroughly  understand  the 
features  of  our  scenery  are  invited  to  peruse  the  various  geological  de 
tails  of  this  report.  They  will  be  necessary,  and  more  besides,  if  one 
would  describe  our  mountains  with  the  pains  which  Ruskin  takes  to  set 
forth  the  causes  that  have  moulded  the  Alps  into  their  present  form. 
Many  may  imagine  it  to  be  of  little  consequence  whether  Mt.  Washing 
ton  be  an  anticlinal  or  synclinal  axis, — whether  it  be  composed  of  granite 
or  slates ;  but  the  decision  of  these  scientific  questions  is  essential  to  the 
proper  delineation  of  its  scenographical  structure.  The  artist,  who  repre 
sents  a  mountain  correctly  upon  canvas,  has  discovered  the  fundamental 
type  of  its  structure,  whether  he  uses  geological  phrases  or  not, — other 
wise  his  painting  will  not  be  recognizable. 

It  is  a  well  known  fact  that  many  surface  configurations  are  due  to  a 
peculiarity  of  rock  formation.  Conical  hills  suggest  a  volcanic  origin; 
and  if  on  examination  they  prove  to  be  composed  of  scorias  or  lava,  the 
evidence  is  plain  of  igneous  eruption.  A  prairie  is  not  merely  an  ex 
panse  of  thick  loam  and  deep  soil;  it  is  underlaid  by  horizontal  layers 
of  rock,  which  give  evenness  to  the  surface  as  truly  as  to  a  table-land. 
Chalk  hills,  not  common  in  the  eastern  half  of  our  continent,  assume 
rounded  and  graceful  undulations  in  consequence  of  the  easily-moulded 
character  of  the  mass.  Similar  shapes  characterize  limestone  hills. 
Ranges  like  that  of  Holyoke  in  Massachusetts  and  Connecticut,  pre 
cipitous  on  one  side  and  sloping  on  the  other,  assume  this  form  in  con 
sequence  of  the  situation  of  the  hard  trap-rock  of  the  mountain.  It 
dips  easterly,  so  as  to  expose  the  tough  edge  of  an  inclined  sheet  high 
up  in  the  air,  and  this  covering  protects  the  underlying  friable  material 
from  denudation.  The  Table  mountains  of  the  Sierra  Nevada  slopes 
are  the  remnants  of  horizontal  igneous  overflows  which  have  never  been 


5QO  PHYSICAL    GEOGRAPHY. 

tilted  up  by  elevating  agencies  like  the  Holyoke  mountains.  The  fall 
ing  of  Niagara  river  over  a  precipice  has  worn  out  a  narrow  gorge  seven 
miles  in  length ;  and  the  cataract  is  receding  every  year,  and  will  con 
tinue  to  move  backwards  till  Lake  Erie  is  reached.  Elsewhere  the  softer 
rocks  may  determine  the  position  of  the  eroding  river. 

I  have  mentioned  these  cases  because  they  are  familiar, — but  take  the 
ground  that  every  one  of  our  hills  and  valleys  has  been  moulded  into 
the  particular  shape  for  which  its  materials  are  fitted  by  the  action  of 
the  sculpturing  agents. 

It  is  also  true  that  rock-sculpture  is  largely  dependent  upon  geograph 
ical  position.  The  Egyptian  traveller  finds  the  chisel-work  of  fifty 
centuries  ago  as  plain  as  that  made  a  year  since  upon  a  New  England 
sandstone.  A  dry  climate  is  adapted  to  preserve,  while  one  charged 
with  moisture  and  cold  rapidly  disintegrates  nearly  every  known  sub 
stance.  Hence  the  same  rocks,  which  are  interminably  channelled  on 
the  eastern  slopes  of  the  Andes,  are  jagged  and  precipitous  on  the  rain 
less  western  sides  of  the  same  range  in  Peru.  No  agent  has  been  more 
effective  than  ice  in  subduing  the  rougher  elements  of  scenery ;  and  for 
this  reason  the  sublime  and  awe-inspiring  elements  are  largely  wanting 
in  our  landscapes.  The  relentless  glaciers  have  removed  the  pinnacles, 
smoothed  the  northern  slopes,  and  toned  down  our  valleys,  allowing  the 
picturesque  feature  to  become  predominant,  and  having  regard,  also,  to 
the  agricultural  necessities  of  the  land. 

The  understanding  of  the  forces  which  have  fashioned  our  topograph 
ical  structure  is  complicated  by  the  great  length  of  time  erosion  has 
been  going  on,  and  the  diverse  character  of  the  agents.  If  our  territory 
constitutes  some  of  the  oldest  dry  land  in  the  country,  as  is  advocated  in 
a  previous  chapter,  not  only  the  rains  and  snows  of  historic  time,  and 
the  glaciers  of  the  Drift  period,  but  the  rains,  snows,  and  ocean  waves  of 
all  geological  time  have  been  at  work  upon  our  rocks,  and  accomplished 
herculean  tasks  of  excavating,  grinding,  and  transporting.  The  result 
has  been  naturally  the  obscuration  of  shapes  which  certain  summits 
would  assume  under  normal  circumstances.  Furthermore,  the  precise 
amount  of  action  in  each  period  is  only  partially  known.  Hence  a  com 
plete  knowledge  of  the  causes  fashioning  our  landscapes  is  of  difficult 
attainment,  and  its  full  enunciation  tedious.  We  must  be  excused,  there- 


SCENOGRAPHICAL    GEOLOGY.  59! 

fore,  for  stating  the  causes  and  methods  of  sculpture  in  general  terms 
only. 

The  special  forms  assumed  by  our  mountains  are  mostly  those  peculiar 
to  the  crystalline  schists,  subsequently  modified  by  glacial  action.  The 
most  readily  distinguishable  are  the  following:  First,  conical  mountains 
having  some  resemblance  to  volcanic  summits,  but  composed  of  the 
earlier  eruptive  rocks,  like  granite,  sienite,  and  protogene.  Second,  long 
reaches  of  rounded  ranges  composed  of  schistose  formations.  To  this 
class  most  of  our  ridges  belong.  Third,  isolated  more  or  less  conical 
masses  of  the  same  class  of  rocks.  Fourth,  deep,  narrow  valleys  of  ero 
sion,  akin  to  gorges  and  canons.  Fifth,  broad,  sloping  valleys.  Sixth, 
plains  formed  by  transportation  of  drift.  Seventh,  terraced  valleys. 
Eighth,  limestone  hummocks.  Every  one  of  these  typical  forms  has 
been  modified  by  the  drift  agency. 

AGENTS  OF  EROSION. 

The  agents  of  erosion  should  be  briefly  mentioned.  They  are  mainly 
atmospheric  disintegration,  rain,  rivers,  glaciers,  icebergs,  ocean,  land 
slides,  and  the  great  northern  Drift.  Each  of  these  agents  has  left 
behind  its  particular  mark,  by  which  the  work  performed  may  be  easily 
identified.  Some  of  them  have  operated  with  greater  intensity  in  the 
by-gone  periods  of  geological  time  than  at  present ;  others  are  supposed 
to  have  been  more  energetic  in  their  action  in  the  more  recent  epochs. 

Atmospheric  disintegration  has  been  the  most  powerful  of  these 
agents  acting  throughout  all  the  periods,  yet  it  is  of  comparatively  little 
consequence  at  the  present  day.  I  refer  especially  to  the  penetration  of 
the  ledges  by  carbonic  acid,  introduced  partly  through  rain-water,  and 
partly  acting  upon  the  surface  by  its  envelopment  of  the  ledges.  Before 
the  Carboniferous  period,  when  a  large  share  of  the  work  of  disintegra 
tion  in  New  Hampshire  had  been  accomplished,  the  atmosphere  con 
tained  a  much  larger  proportion  of  this  reagent  than  it  does  now,  and, 
of  course,  its  action  upon  the  surface  must  have  been  more  manifest.  I 
refer  to  the  decomposition  of  feldspathic  rocks  more  particularly, — a 
reaction  that  has  been  alluded  to  previously  (p.  550), — resulting  in  beds 
of  white  kaoline  clays  and  gravelly  heaps  for  the  residua,  while  the  sal- 
eratus  flows  off  in  the  streams.  Consequently  this  decomposition  is 


592  PHYSICAL    GEOGRAPHY. 

remarkably  clean.  The  clay  is  of  a  variety  used  for  the  manufacture  of 
porcelain  ware ;  and  the  sandy  residuum  in  some  cases  is  pure  enough 
to  be  mistaken  for  loaf-sugar,  as  in  Acworth.  Furthermore,  everything 
about  the  mountains  of  this  character  must  be  clean.  The  waters  will 
be  clear  and  sparkling ;  the  earth  will  hardly  soil  the  hands  by  handling 
it;  the  ledges,  when  uncovered,  will  appear  blanched;  the  sand  and 
gravelly  bottoms  of  rivers  and  ponds  will  not  be  slimy  and  treacherous. 

When  the  attempt  is  made  to  measure  the  amount  of  this  species  of 
denudation,  the  results  are  startling.  Referring  elsewhere  for  the  details, 
it  is  sufficient  to  state  that  the  pre-glacial  erosions  of  our  territory,  due 
mainly  to  this  cause,  have  removed  from  the  present  surface  as  much 
rock  as  now  exists  above  the  level  of  the  sea.  The  average  height  of 
the  land  above  the  ocean  in  New  Hampshire  has  been  estimated  at  1400 
feet  (p.  296).  Our  proposition  maintains  that  the  amount  which  has 
been  removed  from  above  the  existing  surface  is  equal  to  a  blanket  1400 
feet  thick  and  9392  square  miles  in  extent. 

The  markings  left  behind  by  this  kind  of  decomposition  are  less  con 
spicuous  than  the  others,  and  not  so  easily  identified.  Its  tendency  is 
to  crumble  down  bluffs,  blunt  sharp  angles,  and  to  act  simultaneously 
upon  all  sides.  Should  a  stream  of  water  be  diverted  upon  certain 
ledges  undergoing  atmospheric  disintegration,  excavation  will  go  on 
there  more  rapidly  than  elsewhere,  since  the  recently  separated  grains 
of  rock  will  be  washed  away,  and  expose  fresh  surfaces  to  chemical  ac 
tion.  Such  action  would  tend  in  time  to  produce  pinnacles,  such  as 
those  made  known  to  the  public  in  the  Garden  of  the  Gods,  Colorado, 
and  elsewhere  among  the  Rocky  Mountains,  by  means  of  photographs. 
When  these  pinnacles  stand  upon  high  table-lands,  they  will  bear  rela 
tionship  to  the  Needles  or  Aiguilles  of  the  Alps,  referred  by  Mr.  Ruskin 
to  glacial  action  for  their  formation.  In  this  case  the  ice  has  continued 
the  wearing  action  commenced  by  the  rivulets. 

The  action  of  streams  of  water  may  next  command  attention.  Here 
the  fact  of  geographical  position  must  be  taken  into  account.  Two  types 
of  valleys  result  from  this  cause.  In  the  rainless  districts  of  the  south 
west  part  of  our  country,  long  ravines  called  canons  are  abundant. 
Plateaus,  hundreds  of  thousands  of  square  miles  in  extent,  are  traversed 
by  narrow  chasms  cut  down  perpendicularly  by  rivers  and  their  tribu- 


SCENOGRAPHICAL    GEOLOGY.  593 

taries.  These  narrow  gorges  may  be  continuous  for  hundreds  of  miles. 
The  surface  of  the  country  is  dry,  parched,  mostly  without  vegetation, 
both  for  the  want  of  rain  and  the  settling  down  of  all  the  water  flowing 
through  the  country  from  the  moist  regions  higher  up  to  the  bottoms  of 
the  canons,  hundreds  and  sometimes  thousands  of  feet  below  the  general 
level.  The  edges  of  the  ravines  are  sharp,  as  no  tributary  rills  wash 
away  the  projecting  angles.  This  type  of  river  erosion  is  represented 
in  the  well-watered  districts  by  short  gorges,  where  rivers  fall  over  prec 
ipices,  and  gradually  eat  their  way  up  the  channels.  But  the  edges  of 
the  gorges  below  the  cataracts  are  being  gradually  rounded,  and  pass 
insensibly  into  the  other  type  of  river-sculpture. 

The  other  type  is  best  expressed  by  the  general  term  of  valley.  The 
constant  flowing  of  small  streams  down  the  banks  of  rivers  removes  the 
angles  of  the  square  edges  of  the  plateau,  and  there  result  gradual  slopes 
from  the  water's  edge  to  the  dividing  ridge  between  different  hydro- 
graphic  basins.  The  valleys  are  broad  or  narrow  in  proportion  to  the 
amount  of  rain  flowing  down  the  banks,  not  forgetting  that  the  original 
direction  may  have  been  given  to  the  water  by  the  formation  of  synclinal 
basins. 

These  two  types  of  river  action  are  very  marked ;  and  the  geologist, 
by  this  feature,  can  at  first  glance  determine  whether  a  newly-visited 
country  is  a  dry  or  rainless  one,  and,  to  some  extent,  whether  the  rains 
are  abundant  or  limited. 

On  applying  these  criteria  to  New  Hampshire,  we  find  many  examples 
of  interest.  One  immediately  recalls  the  flumes  at  Dixville,  Lincoln, 
and  Nancy's  bridge,  as  similar  to  the  canons.  These,  however,  owe 
their  perpendicularity  to  the  nature  of  the  rocks.  Along  the  river-beds 
are  easily  decomposing  dikes,  which  are  quickly  worn  away  by  the  water. 
Then  the  granite  bordering  the  dikes  is  permeated  by  joints  parallel  to 
the  stream.  The  action  of  water  freezing  in  the  seams  has  pushed  out 
the  first  layer  of  rock  on  each  side,  and  thus  the  flumes  are  quite  wide, 
with  vertical  walls. 

Limited  gorges  are  quite  numerous.  They  are  to  be  explained  either 
by  the  presence  of  softer  rocks  in  the  beds  of  the  streams,  or  by  the  fall 
ing  of  water  over  precipices.  Many  of  them  will  be  noticed  hereafter. 

There  is  a  gradation  from  the  narrow  valleys,  where  water  runs  more

swiftly  to  the  broader  and  gently  descending  expanses.  Cases  of  the 
former  kind  are  in  Wilton,  Lyndeborough,  and  Mont  Vernon.  The 
Souhegan  and  its  tributaries  have  cut  channels  two  or  three  hundred 
feet  deep  out  of  a  plateau.  The  most  of  the  farms  are  upon  the  high 
ground.  Every  river  valley  in  the  state  illustrates  the  type  of  river 
erosion  peculiar  to  the  rainy  districts,  or  the  broader  instances  just  re 
ferred  to,  and  it  is  not  needful  to  specify  examples.  I  do  not  know 
that  the  erosion  has  been  more  thorough  in  those  districts  said  to  re 
ceive  the  greatest  annual  fall  of  rain. 

The  action  of  glaciers  like  those  in  Switzerland  has  not  been  of  great 
importance  in  shaping  our  valleys,  since  so  much  more  important  results 
have  been  produced  by  the  "Drift."  The  local  glaciers  scoop  out  valleys ; 
they  leave  behind  moraines,  either  irregular  mounds  or  small  ridges 
athwart  the  streams,  since  cut  through.  Frequently  the  sides  of  the 
valleys  have  been  left  vertical,  with  ice-markings  upon  the  walls.  These 
mural  surfaces  are  never  extensive. 

Ocean  action  is  peculiar.  Rocks  exposed  to  the  waves  usually  present 
a  precipitous  front,  since  the  wearing  away  takes  place  only  at  the  base 
of  the  cliff.  When  the  ledge  or  bank  of  earth  has  been  undermined,  the 
top  falls  off,  and  thus  a  precipitous  front  is  always  exposed  ocean-wards. 
In  studying  the  landscape  back  from  the  shore,  these  precipitous  cliffs 
may  be  seen  where  there  has  been  a  submergence  in  recent  times,  their 
bases  all  occupying  the  same  level.  Ancient  sea-beaches  usually  accom 
pany  the  former  shore-line  thus  indicated. 

The  most  important  sculptor  has  been  the  ice  of  the  Drift  period. 
Thousands  of  facts  will  describe  minutely  all  the  phenomena  of  this 
sort  hereafter;  but  the  style  of  markings  left  by  them  may  be  readily 
recognized  everywhere.  I  have  for  good  reasons  made  a  broad  distinc 
tion  between  the  Drift  and  local  glaciers,  the  latter  having  exerted  very 
feeble  influences  as  compared  with  the  former.  Every  mountain  and 
rocky  hill  in  the  state,  except  the  upper  five-hundred  feet  of  the  Mt. 
Washington  cone,  show  the  markings  of  this  mighty  rock-breaker ;  and 
therefore  its  influence  has  been  more  potent  in  giving  the  present  shapes 
to  our  scenery  than  that  of  all  the  other  agents  combined. 

The  distinguishing  mark  of  ice-action  in  the  Drift  period  is  the  round 
ing  and  smoothing  of  the  ledges.  Invariably  our  rocks  have  been  rounded 


SCENOGRAPHICAL   GEOLOGY.  595 

by  a  force  proceeding  southerly.  Whether  you  examine  the  bosses  of 
rock  in  the  Connecticut  valley,  the  Mt.  Washington  ridge,  or  the  islands 
of  Winnipiseogee,  every  one  that  has  not  been  shattered  by  the  frost  of 
more  modern  winters  shows  a  distinct  smoothing  and  rounding  upon  the 
north  side,  while  upon  the  south  the  original  roughness  is  preserved.  The 
terms  stoss,  or  struck,  and  Ice  have  been  applied  to  these  two  varieties 
of  appearance.  Their  origin  is  obvious.  The  immense  ice  sheet  in 
pushing  southerly  strikes  every  ledge  with  prodigious  energy;  and  the 
flinty  fragments  frozen  into  the  congealed  mass  will  break  off  all  rock 
projections  in  the  way,  and  smooth  over  that  which  is  too  solid  to  be 
broken.  And  this  force  will  be  exerted  entirely  upon  the  sides  that  re 
ceive  the  blows, — consequently  the  lee  surfaces  will  be  rough  and  jagged. 
This  action  shows  why  we  have  no  pinnacles  of  rock,  such  as  abound  in 
the  Alps.  The  Swiss  glaciers  have  plowed  around  these  pinnacles,  and 
left  them  standing ;  but  the  American  continental  Drift  was  of  such  vast 
proportions  that  the  needles  disappeared  as  though  they  were  pebbles  in 
the  path  of  the  ordinary  river  of  ice.  This  statement  is  intended  to 
apply  only  to  North  America  east  of  the  Missouri  and  north  of  the  Ohio 
rivers. 

For  examples  of  this  action  on  a  small  scale,  let  every  New  Hampshire 
reader  search  out  the  nearest  freshly  uncovered  ledge  to  his  residence, 
and  the  markings  will  show  themselves  to  his  view,  for  they  are  every 
where.  Then  observe  the  shapes  of  mountains.  Look  at  the  profile  of 
Mt.  Kearsarge,  as  seen  from  the  east  or  west  sides.  There  is  a  grand, 
smooth,  unbroken  slope  from  the  valley  of  the  Blackwater  to  the  very 
summit,  including  a  small  foot-hill ;  while  upon  the  south  you  observe 
irregular  hills,  the  "Mission  ridge,"  "Plumbago  point,"  and  other  irregu 
larities,  where  the  ice  passed  over  lightly  without  scraping  off  everything 
down  to  the  base.  Monadnock  shows  the  rounding  very  prominently 
upon  the  northern  slopes,  but  near  inspection  is  requisite  to  reveal  the 
jaggedness  on  the  south.  Figs.  63  and  64,  on  pages  540  and  541,  show 
the  stoss  and  lee  sides,  though  the  smallness  of  the  scale  of  illustration 
impairs  the  clearness  of  representation.  The  backs  of  Mts.  Jefferson 
and  Adams  have  been  smoothed  over,  their  ledges,  when  stripped  of 
moss  and  trees,  revealing  the  striations  and  polishing,  while  in  the  pict 
ure  only  a  general  rounding  is  apparent.  In  the  other  sketch,  the 


596  PHYSICAL    GEOGRAPHY. 

precipitous  southern  slopes  of  the  same  mountains  illustrate  their  primi 
tive  character.  Another  sketch,  showing  the  abruptness  of  the  lee  sides 
of  mountains,  appears  on  page  12.  Fig.  22,  of  Mt.  Carter  from  Gorham, 
may  also  illustrate  the  long  slope  on  the  north  smoothed  by  the  ice- 
graver,  while  the  south  side  is  precipitous.  The  mass  simply  fell  over 
it,  without  making  any  impression. 

The  nearest  approach  to  a  pinnacle  in  New  Hampshire  is  Mt.  Cho- 
corua,  shown  in  Figs.  31  and  61.  But  the  back  side  of  this  sharp 
summit  is  marked  quite  abundantly  by  the  peculiar  striations  left  by 
the  Drift.  Hence,  though  one  needs  to  stand  on  the  summit  to  per 
ceive  the  difference  between  the  stoss  and  lee  sides,  it  is  evident  a  long 
spire  was  broken  off  when  the  ice  went  over  Mt.  Chocorua. 

A  still  more  common  ice-mark  than  the  sculpturing  of  the  ledges  is 
seen  in  the  formation  of  the  piles  of  rubbish  transported  from  their 
original  locations  in  the  solid  ledges,  and  strewn  broadcast  over  the  hills 
and  plains.  The  local  glaciers  often  transport  blocks  of  stone  upon  their 
backs;  and  in  like  manner  our  Drift  has  carried  boulders  scores  and 
hundreds  of  miles.  But  there  is  reason  to  believe  that  the  principal 
portion  of  the  earth-mass  known  as  hardpan,  and  the  majority  of  the 
accumulations  seen  in  our  walks,  have  been  pushed  along  under  the  ice. 
Consequently  the  arrangement  of  the  rubbish  is  less  orderly  than  in  the 
moraines  of  the  smaller  glaciers.  The  earth  and  stones  have  been 
dumped  over  precipices,  filled  up  holes,  levelled  over  irregular  surfaces 
into  plains,  etc.  This  action  has  been  very  beneficial  in  preparing  the 
country  to  support  forests  and  most  agricultural  products.  But  besides 
the  deposition  of  the  hardpan,  the  materials  have  also  been  left  in  innu 
merable  localities  in  the  form  of  conical  and  ridged  hills,  straight,  tortu 
ous,  and  irregular.  Large  boulders  abound  in  many  districts,  often  so 
numerously  as  to  render  the  smoothing  of  extensive  fields  by  their  re 
moval  practically  impossible.  From  a  scenographic  point  of  view,  these 
boulders  are  often  attractive,  as,  for  examples,  the  boulders  in  Bartlett 
and  Conway,  shown  by  heliotypes  in  the  next  volume,  Vessel  rock  in 
Gilsum,  Ordination  rock  in  Tamworth,  and  others.  A  good  example  of 
a  number  of  blocks  is  the  stereograph  entitled  "New  Hampshire  Cow- 
Pasture,"  in  Stratford. 

The  surfaces  smoothed  by  ice  are  readily  distinguished  from  those 


SCENOGRAPHICAL    GEOLOGY.  5Q7 

polished  by  water-action.  The  former  usually  exhibit  striations  parallel 
with  one  another,  and  which  also  show  the  direction  taken  by  the  cur 
rent.  The  ledge  covered  by  them  may  feel  rough  to  the  hand,  but  to 
the  eye  appears  rounded  in  a  general  way.  The  latter  are  smooth  to  the 
touch,  unless  the  rock  is  very  coarse  in  texture;  but  there  is  not  the 
general  rounding  of  the  mass,  as  seen  in  the  other  type  of  sculpture. 
The  surface  may  be  covered  by  a  multitude  of  minor  irregularities. 
This  type  of  smoothness  is  best  seen  on  boulders  and  ledges  along  the 
beds  of  mountain  torrents. 

The  action  of  frost  greatly  assists  in  the  work  of  disintegrating  ledges. 
In  the  colder  months  water  penetrates  the  crevices  of  ledges,  and  then 
freezes.  As  water  expands  in  freezing,  the  effect  is  seen  in  the  breaking 
off  of  larger  or  smaller  fragments  of  rock  from  the  ledge.  Certain  situ 
ations  are  especially  favorable  for  this  type  of  action.  One  is  upon  the 
summits  of  the  higher  mountains.  The  finest  known  example  is  upon 
the  summit  of  Mt.  Washington,  and,  to  illustrate  it,  a  heliotype  has  been 
taken.  By  referring  to  it,  the  reader  will  observe  large,  angular  masses 
of  rock  scattered  about  promiscuously,  just  as  they  fell  off  from  still 
larger  masses.  Some  of  these  are  permeated  by  cracks,  which  will  by 
and  by  enlarge,  and  again  fracture  the  rock  in  the  same  way  that  has 
been  described.  The  process  of  freezing  and  crumbling  will  go  on  so 
long  as  the  particles  are  capable  of  division.  The  seams  are  originally 
the  jointed  structure  of  the  ledges,  and  ultimately  the  natural  cleavage 
planes  of  the  constituent  minerals.  The  visitor  may  search  in  vain  over 
Mt.  Washington  for  any  evidence  of  transported  rock,  save  what  may 
have  been  brought  by  human  agency;  and  a  few  minutes'  walk  over  the 
fragments  will  prove  what  a  difference  there  is  in  the  distribution  of 
blocks  of  stone,  by  the  action  of  frost  and  gravity  combined,  as  compared 
with  the  arrangement  of  water-worn  stones  in  a  river,  or  the  scattered 
boulders  of  drift  origin.  The  house  in  the  view  is  known  as  the  Tip-top, 
built  of  fragments  similar  to  those  by  which  it  is  surrounded.  The  view 
was  taken  before  so  much  of  the  summit  had  been  covered  by  edifices 
as  is  now  apparent  to  the  visitor. 

Fig.  10  will  give  a  general  idea  of  these  blocks  of  stone,  when  viewed 
from  some  distance  below  the  summit.  Though  taken  in  the  winter, 
when  the  interspaces  were  filled  with  snow  and  ice,  the  effect  is  the 


598 


PHYSICAL    GEOGRAPHY. 


same  to  the  eye  as  in  the  heliotype.  On  walking  over  the  mountain,  one 
can  observe  every  stage  of  the  process  of  decomposition.  At  first  there 
may  be  a  ledge,  with  pieces  slightly  removed  from  it.  Next,  one  will  be 
troubled  to  decide  whether  a  series  of  fragments  occupies  the  original 
space  of  the  ledge,  so  that  the  position  of  the  strata  can  be  accurately 
determined,  or  whether  the  blocks  have  been  removed  out  of  place.  In 
other  piles  there  will  be  no  question  that  every  trace  of  the  original 
stratigraphical  structure  has  vanished.  From  these  heaps  there  is  an 
unbroken  series  to  the  piles  of  angular  gravel  and  sand,  which  have 
resulted  from  continued  decomposition.  The  extreme  is  where  the  sand

Mt.  Washington  rises  back  of  the  debris. 

has  allowed  vegetation  to  grow,  and  to  accumulate  a  mould  fitted  for  the 
development  of  the  few  hardy  flowers  and  miniature  trees  of  the  alpine 
district. 

The  more  common  case  of  disintegration  through  frost  may  be  seen 
along  the  sides  and  at  the  bases  of  precipices.     Several  of  our  figures 


SCENOGRAPHICAL    GEOLOGY.  599 

illustrate  the  process.     Consult  figures  on  pp.  12  and  28,  and  Figs.  31, 
36,  63,  71,  72,  79,  and  82  to  86. 

An  intermediate  step  in  the  process  is  illustrated  in  Fig.  71,  the  type 
of  a  very  common  state  of  things  among  our  high  mountains.  The 
loose  blocks  accumulate  so  abundantly  that  most  of  the  precipice  has 
disappeared,  and  the  fragments  assume  their  natural  angle  of  thirty-five 
degrees  with  the  horizon,  so  as  to  render  walking  up  the  slope  a  matter 
of  considerable  difficulty.  The  one  who  goes  first  disturbs  the  equilib 
rium  of  some  loose  block,  and  it  rolls  down  the  hill,  greatly  to  the  dis 
comfort  of  those  who  follow.  These  fragments  are  slaty.  When  granitic 
in  character,  and  the  disintegration  has  proceeded  further,  slides  often 
result.  After  the  rapid,  thorough  saturation  of  the  gravelly  mass  with 
water,  it  becomes  semi-fluid  in  its  properties,  and  great  portions  of  it 
slide  to  the  bottom  of  the  valley,  often  devastating  fertile  fields  and 
destroying  lives  in  consequence  of  the  suddenness  of  the  slipping. 
Another  interesting  view  of  the  accumulation  of  fragments  by  frost 
disintegration  appears  in  the  copy  of  Mr.  Morse's  drawing  of  Carrigain 
notch. 

SCULPTURING  OF  GRANITIC  ROCKS. 

The  first  of  the  rocks,  whose  peculiar  mineral  composition  gives  rise  to 
characteristic  scenic  forms,  are  the  Granitic.  The  simplest  case  is  that 
of  a  mountain  like  Chocorua  (Figs.  31  and  61)  or  Pequawket  (heliotype, 
Vol.  II).  It  is  a  conical  mountain,  with  a  sharp  summit,  and  not  trun 
cated  like  the  volcano.  Other  examples  are  Mts.  Monadnock,  Ascutney, 
and  Black,  near  the  Connecticut  in  Vermont.  The  more  complicated 
cases  are  where  several  conical  peaks  are  grouped  together.  The  two 
Percy  peaks  in  Stratford  afford  a  very  fine  example,  as  shown  in  a  helio 
type  illustrating  Chapter  XIX.  Others  are  the  Stratford  and  Columbia 
peaks,  numerous  eminences  in  Essex  county,  the  Orange  mountains 
east  of  Montpelier,  Vt,  Profile,  Tremont,  and  Haystack  in  the  Saco  val 
ley,  Crawford,  Resolution,  Iron,  and  others  north  of  the  Saco,  Tripyramid, 
several  others  in  Pemigewasset,  Gunstock  and  Belknap,  Red  hill,  Green 
mountains  in  Effingham,  Moose  mountain  near  Wolfeborough,  Iron-ore 
hill  near  Haverhill,  range  of  mountains  in  the  west  part  of  Benton,  Mote 
mountains  in  Albany,  and  others.

PHYSICAL    GEOGRAPHY. 


The  origin  of  the  conical  form  may  be  due  to  three  causes: — First,  to 
the  original  shape  of  the  materials.  Our  granite  mountains  have  been 
erupted  from  below,  and,  when  the  entire  mass  is  limited  in  amount,  it 
would  naturally  be  conical,  the  pasty  substance  tending  to  flow  centrif- 
ugally  from  the  vent.  Secondly,  the  tendency  of  denudation  is  to  wear 
away  the  summits  of  mountains.  The  forces  act  powerfully  upon  the 
exposed  ledges  at  the  tops,  and  the  fragments  will  seek  the  bases  of  the 
hills,  thus  tending  to  the  cone  in  form.  Thirdly,  the  more  energetic 
action  of  denudation  in  granite  mountains  is  caused  by  a  sort  of  con 
centric  structure  in  cliffs.  A  good  example  occurs  in  Benton,  near  the 
summit  of  the  Boston,  Concord  &  Montreal  Railroad,  as  one  looks  north 
erly  upon  the  steep  side  of  Owl's  Head.  Another  may  be  seen  in  the 


Fig.  72. — WELCH  MOUNTAIN,  FROM  CAMPTON. 

heliotype  of  Eagle  cliff  in  Volume  II,  where  the  vertical  wall  of  Profile 
mountain,  on  the  left-hand  side,  shows  the  concentric,  nearly  vertical, 
slabs  of  granite  peeling  off  and  falling  to  the  base  of  the  cliff.  The 
steep  sides  of  Carrigain  notch  (see  sketch)  have  been  produced  in  the 
same  way.  The  right-hand  slope  in  Fig.  9  shows  the  base  of  a  cliff 
opposite  the  Willey  house,  where  similar  action  has  taken  place.  A 
heliotype  shows  the  same  thing  upon  both  sides  of  the  Notch,  in  the 


SCENOGRAPHICAL    GEOLOGY. 


6O I 


view  down  the  valley  from  Mt.  Willard.  Fig.  72  also  illustrates  this  ten 
dency  to  split,  less  perfectly  than  some  others ;  but  the  steep  sides  show 
where  great  masses  of  granite  have  been  excavated,  and  the  fragments 
washed  down  the  tributaries  of  the  Pemigewasset.  The  contrast  in  the 
kind  of  rock  may  be  seen  by  the  presence  or  the  scantiness  of  vege 
tation,  as  well  as  by  the  position  of  the  granitic  piles  in  the  background. 
The  bare  rocks  exhibit  many  harmonies  of  color,  offsetting  the  grays 
with  neutral  hues  of  blue  and  white,  which,  at  sunrise  and  sunset,  are 
intensified. 

This  tendency  to  split  does  not  extend  very  deeply  into  the  rock.  It 
seems  to  be  induced  largely  by  the  action  of  the  weather,  and  has  been 
observed  about  the  Quincy  (Mass.)  quarries  by  Shaler,  and  also  by  Hunt. 
Perhaps  a  similar  action  is  that  made  of  practical  service  in  removing 
boulders  from  a  field.  The  farmer  builds  a  hot  fire  over  the  granite 
blocks  he  wishes  to  remove.  Then,  by  throwing  water  upon  them  while 
heated,  large  flakes  scale  off,  and  thus  rocks  too  large  to  be  transported 
bodily  can  be  removed  in  a  very  little  while.  The  flaking  off  always 
conforms  to  the  surface  of  the  stone,  very  much  like  the  clearing  of  the 
larger  masses  from  cliffs.  I  understand  the  arrangement  of  the  Con 
cord  and  other 


granites,  in  flat 
sheets,  as  seen 
in  the  quarries, 
to  be  quite  a  dif 
ferent  phenome 
non.

and  Liberty,  are  represented.     The  very  apex   of   these  mountains  is 
composed  of  compact  feldspar,  which  disintegrates  the  same  as  granite, 
and   therefore  has  not  varied   the  typical   form   of   the   decomposition.

6O2  PHYSICAL   GEOGRAPHY. 

From  the  Flume  house  one  can  look  squarely  across  to  the  depression 
between  Mts.  Liberty  and  Flume  and  perceive  the  same  granitic  round 
ness,  as  well  as  in  the  Coolidge  mountains  farther  south.  The  view  in 
the  sketch  is  a  very  faint  approach  to  the  view  of  the  Aiguilles  of  Mt. 
Blanc  from  the  vale  of  Chamouni,  for  the  great  extent  of  the  base  of 
the  Lafayette  mountains  conceals  the  proper  proportions  of  the  summits 
from  this  point  of  view.  If  one  climbs  the  small  Mt.  Pemigewasset, 
back  of  the  Flume  house,  he  will  see  this  range  in  all  its  grandeur. 
There  is  a  carriage-road  to  its  summit  from  the  hotel. 

At  this  point  it  may  be  well  to  call  attention  to  a  peculiarity  of  certain 
granitic  mountains  exhibited  upon  our  heliotype  of  the  White  horse  ledge 
in  Conway.  It  is  traversed  by  lines  streaming  down  from  the  summit 
towards  the  water  of  Echo  lake.  Similar  lines  appear  in  photographs  of 
the  South  Dome  of  the  Yosemite  valley  in  California,  and  other  similar 
bluffs.  At  first  I  thought  them  due  to  a  peculiar  structure  of  the  rock, — 
perhaps  vertical  joints ;  but  a  nearer  inspection  shows  them  to  be  the 
result  of  rain-water  flowing  down  the  cliff,  and  renovating  certain  parts 
of  the  vegetation,  and  in  others  changing  the  shade  of  color.  This  cliff 
also  shows  a  little  tendency  to  cleave  off  concentrically.  The  nearness 
of  this  cliff  to  North  Conway,  and  the  beautiful  reflection  of  it  in  the 
waters  of  Echo  lake,  render  it  a  place  very  attractive,  and  much  fre 
quented  by  visitors.  The  resemblance  of  the  lighter  markings,  on  the 
right-hand  side  of  the  view,  to  the  head  and  front  part  of  the  body  of  a 
horse,  is  really  too  indefinite  to  render  the  name  an  appropriate  one. 
The  ledge  must  be  about  700  feet  high.  The  one  to  the  north  is  960 
feet  above  the  Saco  meadows. 

Profiles.  Among  the  accidental  shapes,  left  by  the  granite  on  the 
cliffs  back  of  Profile  lake  in  Franconia,  is  the  outline  of  a  human  face 
known  as  the  Old  Man  of  the  Mountains  (Fig.  45),  and  one  of  the  most 
attractive  features  in  the  landscape  in  this  part  of  the  country.  Most  of 
the  facial  features  are  present, — the  forehead,  eyebrows,  nose,  mouth,  and 
chin, — and  well  proportioned  to  one  another.  (Fig.  74  is  roughly  copied 
from  the  lithograph  of  Oakes,  after  a  drawing  by  Sprague.)  It  has  been

in  a  northerly  direction.     If  you  go  a  short  distance  either  to  the  right 
or  the  left  of  this  line,  the  shape  of  the  face  is  distorted,  and  disappears.

PHYSICAL    GEOGRAPHY. 


The  profile  is  made  of 
Jio  three  jutting  masses  of 
jH    rock,  in  different  verti-

%    makes    the    forehead, 
g    the   second   the    nose 
«    and  upper  lip,  and  the 
third   the   chin.     The 
rock  is  about  1 200  feet 
above  the  lake,  and  40 
feet    in    length.     Mr. 
Oakes  puts  the  length, 
from    the   top   of   the 
forehead  to  the  lowest 

in    point  of   the  chin,  at

gers.  The  ledge  is  extensive,  however,  and  may  stand  for  scores  of 
years ;  but  I  would  advise  any  persons  who  are  anxious  to  see  the  Profile 
for  themselves,  to  hasten  to  the  spot,  for  fear  of  disappointment.  I 
should  also  question  the  presumption  entertained  by  many  that  the  Pro 
file  was  probably  known  to  the  aborigines,  who  are  supposed  to  have 
gazed  upon  it  with  superstitious  awe.  They  have  given  us  no  legends 
concerning  it ;  and  its  easily  decomposing  character  would  suggest  that 
it  may  not  have  existed  in  its  present  shape  for  many  centuries  back. 
The  first  notice  I  can  find  of  it  is  contained  in  a  description  and  figure, 
by  Gen.  Martin  Field,  published  in  1828  in  the  American  Journal  of 
Science,  I  vol.  xiv,  p.  64.*  It  was  discovered  not  long  previously  in  laying 
out  the  road  through  the  Notch.  The  proper  place  to  see  the  Profile  is 
on  the  carriage-road,  about  a  quarter  of  a  mile  east  of  the  Profile  house, 
and  close  by  the  lake.  The  figure  varies  from  different  points  of  view. 
Seen  from  the  road,  the  expression  is  somewhat  severe  and  melancholy. 
Views  taken  from  nearer  the  object,  up  the  pile  of  fragments,  show  him 
to  be  much  better  natured.  Oakes  remarks  that  the  "face  of  the  'Old 
Man  of  the  Mountains'  is  set,  and  his  countenance  fixed  and  firm.  He 
neither  blinks  at  the  near  flashes  of  lightning  beneath  his  nose,  nor 
flinches  from  the  driving  snow  and  sleet  of  the  Franconia  winter,  which 
makes  the  very  mercury  of  the  thermometer  shrink  into  the  bulb  and 
congeal." 

In  passing  to  the  left,  the  chin  sharpens ;  then  the  teeth,  as  it  were, 
have  fallen  out,  and  there  is  a  cap  over  the  forehead.  In  continuing  to 
the  left,  the  lower  part  of  the  face  begins  to  fall  away,  and  is  entirely  out 
of  sight,  while  the  cap  and  nose  remain  essentially  entire.  The  nose 
and  face  become  flattened  in  passing  to  the  right,  and  soon  only  the 
forehead  remains.  The  original  of  the  vignette  was  copied  from  a  pho 
tograph. 

This  face  has  been  celebrated  in  Hawthorne's  tale  of  "The  Great 
Stone  Face,"  and  in  "Christus  Judex." 

Upon  Mt.  Jefferson  there  is  another  arrangement  of  rocks  bearing 
some  resemblance  to  a  human  countenance,  with  a  cap  on  the  head.  It 
is  known  as  the  "  Sentinel,"  and  is  rarely  visited.  It  is  formed  by  schis-

please  to  compare  it  with  the  vignette  on  the  title-page.

tose  rocks.     In  the  gate  of  the  Notch,  near  the  Crawford  house,  several 
inferior  profiles  have  been  pointed  out,  as  the  "Old  maid,"  "Young  man," 


Fig.   76. — THE   SENTINEL. 

"The  baby,"  etc.,  but  the  resemblances  are  not  striking.  Perhaps  the 
best  rocky  face  in  the  state,  next  to  the  Profile,  is  the  "Old  Man  of  Dix- 
ville." 

FEATURES  OF  LONG  RANGES  OF  SCHIST. 

The  more  common  variety  of  our  scenery  is  based  upon  modifications 
of  long  reaches  of  micaceous  schists.  The  scenery  is  less  pronounced 
than  that  characteristic  of  a  granitic  foundation,  since  the  rock  decom 
poses  with  difficulty.  The  shapes  of  the  mountains  of  this  rock  depend 
chiefly  upon  their  original  position,  as  determined  by  elevation.  Where 
the  forces  have  acted  normally,  there  results  a  long  range  with  rounded 
surface,  like  a  mid-ocean  wave  of  corresponding  length.  In  the  case 
of  dislocations,  the  mountains  will  stop  short  at  the  line  of  fracture. 
When  more  than  one  series  of  elevations  has  affected  the  mass,  the 
composite  character  of  the  resulting  eminences  may  be  observed. 

Such  features  of  elevation  and  disturbance  as  have  been  noticed  about 
the  Mt.  Washington  range  are  of  considerable  consequence,  since  the 
district  is  better  known  than  most  others,  and  presents  the  grandest 
elements  in  our  scenery. 

There  are  two  ways  of  looking  at  this  range, — from  the  side,  or  from 
the  ends,  somewhat  tangentially.  Of  the  former,  the  views  from  Beth 
lehem,  Littleton,  Whitefield,  and  the  vicinity  of  the  Fabyan  house  are 


SCENOGRAPHICAL    GEOLOGY.  6o/ 

the  best  from  the  west,  unless  you  choose  to  climb  various  peaks  and 
mountains.  The  near  easterly  view  from  the  Glen  house  on  the  east  is 
quite  imposing.  As  the  country  is  entirely  unsettled  on  the  east,  in  the 
immediate  neighborhood  of  the  mountains,  it  is  not  so  easy  to  get  a 
satisfactory  view  from  this  quarter  ;  but  one  nearly  as  good  may  be 
obtained  from  the  hills  back  of  Jackson,  of  which  I  had  hoped  to  present 
a  heliotype  for  the  frontispiece,  but  have  been  unsuccessful,  because  of 
the  difficulty  of  obtaining  a  clear  negative  at  such  a  great  distance. 
From  this  point  Washington  is  seen  to  stand  much  higher  than  his 
brother  peaks,  and  the  deep  ravines  on  his  south-eastern  side  are  clearly 
defined. 

Our  heliotype  from  near  the  Fabyan  house,  about  a  mile  and  a  half 
east,  gives  us  a  good  view  of  the  mountains,  as  a  range,  from  Jefferson 
to  Clinton.  Washington  is  notably  the  highest  of  the  peaks,  showing  a 
slight  depression  in  the  middle  of  what  is  properly  the  summit.  The 
west  side  is  cut  by  two  rough  valleys.  On  its  north-east  ridge  may  be 
seen  the  winding  course  of  the  railway.  On  the  left,  Mt.  Clay  seems 
quite  insignificant.  Of  the  peaks  on  the  right  of  Washington, — Monroe, 
Franklin,  and  Pleasant, — the  latter  is  the  most  conspicuous,  because  higher 
than  those  immediately  adjacent,  and  the  curious  hollowing  out  of  the 
front  side  by  streams.  Fig.  25  presents  a  part  of  this  heliotype,  as 
sketched  by  hand.  The  artist  plainly  exaggerates  the  relative  heights 
of  the  several  summits  and  ravines,  as  may  be  seen  by  carefully  compar 
ing  the  sketch  with  the  photograph ;  but  it  is  almost  impossible  to  avoid 
exaggerating  any  magnificent  view  with  the  pencil.  The  mind  compels 
the  hand  to  reproduce  the  effect  received  by  an  inspection  of  the  scene, 
and  it  cannot  be  done  well  in  any  other  way. 

In  Fig.  77  we  have  a  view  of  the  Mt.  Washington  range  from  Milan, 
a  direction  slightly  east  of  north.  The  central  peak,  seemingly  the 
highest,  and  with  an  immense  piece  hollowed  out,  is  Mt.  Adams,  with 
a  double  summit.  Beyond,  to  the  right,  is  Mt.  Jefferson.  The  most 
prominent  peak  on  the  left  is  Mt.  Madison.  Back  of  the  deep  cleft, 
called  King's  ravine,  between  Adams  and  Madison,  faintly  rises  Wash 
ington.  In  the  foreground  the  Androscoggin  valley  shows  itself,  first 
running  towards  Madison,  then  turning  south-westerly  towards  Adams, 
before  curving  around  the  farthest  of  the  smaller  hills  to  flow  out  of  the 


6o8 


PHYSICAL    GEOGRAPHY. 


scene  to  Gorham.  The  hamlet  directly  in  front  is  Milan.  This  was  one 
of  the  favorite  points  of  view  with  Starr  King,  who  regretted  that  so 
few  persons  among  the  great  travelling  public  ever  attain  to  it.  It  is 
of  easy  access,  either  by  a  carriage-drive  of  a  dozen  miles  from  Gorham, 


or  a  walk  of  a  mile  or  two  from  the  Milan  station  on  the  Grand  Trunk 
Railway.  There  is  a  country  inn  at  Milan,  where  travellers  are  always 
welcome. 

These  views  give  the  idea  of  a  long  range  with  minor  undulations. 


SCENOGRAPHICAL    GEOLOGY.  609 

The  suggestion  has  been  made  of  the  existence  of  a  fault  in  ancient 
times,  which  lifted  this  range  abruptly  above  the  Saco  valley,  on  the 
side  of  Mt.  Webster.  The  change  from  the  Androscoggin  valley  is 
less  abrupt  to  Madison,  there  being  a  gradual  descent  through  the  inter 
vening  Pine  hill,  not  shown  in  the  last  figure.  The  action  of  the  Andros 
coggin  river  has  deepened  the  gap  naturally  existing  between  Pine  hill 
and  Mt.  Hayes ;  but  we  have  here  no  evidence  of  an  upthrow  or  down 
throw  on  either  side. 

There  have  been  not  less  than  three  attempts  of  the  forces  of  nature 
to  throw  up  this  range.  The  first  evidently  produced  a  wave-like  ridge, 
much  like  its  present  form,  but  not  so  elevated.  One  of  the  others  acted 
in  the  same  direction,  and  therefore  cannot  be  distinguished  from  the 
first  in  its  effects.  But  the  third  force  pushed  from  a  direction  at  right 
angles  nearly  to  the  others.  Its  effects  can  be  conceived  by  imagining 
an  ocean  wave  to  become  fixed,  while  it  is  allowed  to  have  a  plastic  con 
stitution.  Supposing,  now,  that  some  force  pushes  this  plastic  material 
in  the  direction  of  its  length,  it  is  clear  that  there  will  be  a  ridging  up 
which  will  tend  to  elevate  disproportionately  certain  parts  of  the  wave. 
Such  action  has  taken  place  in  this  range,  as  its  indications  are  manifest 
in  the  contortions  of  the  strata,  and  its  effects  must  have  been  perma 
nently  impressed  upon  the  figure  of  the  mountain. 

I  am  disposed  to  think  that  Washington,  Jefferson,  Adams,  and  Madi 
son  owe  their  conical  shapes  to  the  crushing  action  of  the  last  mentioned 
of  the  three  forces  of  elevation.  If  you  examine  carefully  the  positions 
of  the  strata  upon  these  summits,  you  will  perceive  great  irregularity  and 
constant  variation,  just  as  if  the  plastic  material  had  been  crowded  into 
heaps.  But  all  the  notches  have  been  intensified  by  erosion,  as  well  as 
the  valley  of  the  west  branch  of  the  Peabody  river,  shown  conspicuously 
in  Figs.  63  and  70,  and  less  so  in  Figs.  79  and  85. 

Another  marked  feature  of  the  higher  regions  is  its  plateau  character. 
It  is  best  seen  in  the  heliotype  view  of  Mt.  Washington  from  the  south 
east.  On  descending  to  the  Lake  of  the  Clouds,  the  explorer  will  find  a 
very  flat  region,  running  out  easterly  into  Boott's  Spur,  and  northerly 
along  the  east  side  of  Washington.  The  Great  Gulf,  between  Washing 
ton  and  the  three  contiguous  peaks  of  Jefferson,  Adams,  and  Madison,  is 

only  a  gorge  cut  out  of  the  plateau,  as  we  can  easily  imagine  on  looking 
VOL.  i.     79

PHYSICAL    GEOGRAPHY. 


northerly  from  the  Tip-top  house,  or  at  Figs.  79  and  85.  But  the  view 
from  the  south-east  shows  the  plateau  best,  and  if  it  had  been  taken  from 
a  point  a  little  farther  east,  the  feature  would  show  itself  more  promi 
nently,  as  in  the  last  of  Oakes's  lithographs.  The  abyss  in  front  is 
Tuckerman's  ravine,  with  tributary  scallopings  on  the  north-west  sides. 
The  erosion  has  been  vertical,  just  as  in  a  gorge  worn  out  of  a  level 
plain.  It  is  impossible  to  descend  with  safety  down  the  sides  of  this 
ravine  in  most  places.  And  the  accessible  portions  have  been  rendered 
less  precipitous  by  the  accumulation  of  loose  material,  through  slides  and 
atmospheric  disintegration.  Oakes's  gulf  and  Hunting-ton's  ravine  are 
other  deep  gorges  excavated  out  of  this  plateau.  This  table-land  is  less 
than  ten  miles  in  length,  and  somewhat  over  5000  feet  in  elevation. 

We  think,  therefore,  the  proper  structure  of  the  Washington  group  of 
summits  is  best  expressed  by  the  supposition  of  a  plateau,  out  of  which 


Fig.   78. — MTS.    ADAMS  AND   MADISON. 

From  near  Randolph  hill. 


four  great  ravines  have  been  excavated,  and  upon  which  lateral  forces 
have  piled  up  comparatively  inferior  heaps  of  contorted  rock,  constitut 
ing  the  presidential  summits.  With  these  suggestions  in  mind,  the 
tourist  will  easily  see  the  reasons  for  the  special  fashioning  of  every 
elevation  and  depression  in  the  Montalban  area. 

The  modifications   induced  by  stratigraphical  structure  are  perhaps 


SCENOGRAPHICAL    GEOLOGY. 


6n 


lesp  important  than  what  have  been  described.  The  shape  of  the  range 
is  like  that  assumed  by  hills  with  a  monoclinal  dip,  while  the  structure  is 
that  of  an  inverted  anticlinal  axis.  There  would  also  seem  to  be  a  syn 
clinal  basin  on  the  east,  separating  the  range  from  the  Carter  mountains 
in  Bean's  Purchase.  The  structure  of  the  latter  line  of  elevations  is  not 
well  understood.  It  is  often  the  case  on  Washington  that  the  inversion 
does  not  appear  at  the  bottoms  of  the  great  ravines.  In  the  Peabody 
River  (west  branch)  gulf  the  dip  is  easterly,  while  high  up  on  the  moun 
tain's  flank  the  reversed  north-westerly  inclination  is  apparent. 

The  great  water-shed  of  the  state,  south  of  Franconia,  is  maintained 
in  its  present  position,  for  stratigraphical  reasons.  The  axis  of  the  ridge 
is  a  very  hard,  unyielding  granite,  which  has  sternly  resisted  all  efforts  at 
thorough  disintegration  from  the  earliest  times.  It  is  an  interesting  fact 
that  this  range  should  be  essentially  parallel  to  the  anticlinal  ridge  of  the 
Green  Mountains,  both  being  of  nearly  the  same  age. 

A  few  other  interesting  views  of  the  great  range  of  mountains  may  be 
noticed  here.  On  page  3  Mt.  Madison  is  seen  to  loom  up  majestically, 
as  it  is  viewed  from  Shelburne.  Fig.  60  is  a  similar  sketch,  from  the 


Fig.   79. — WASHINGTON,    CLAY,    AND  JEFFERSON,  FROM   ADAMS. 

Lead  Mine  bridge,  one  of  the  favorite  localities  to  be  reached  from  Gor- 
ham.  Fig.  67  seems  to  be  from  a  point  intermediate  between  the  others. 
In  all  of  these,  Washington  appears  quite  inferior  by  the  side  of  the 
more  conspicuous  eminence. 

The  views   from  the   north  of   the   same   mountains  give  a  greater

breadth  of  base  than  those  from  Shelburne,  as  in  Figs.  78  and  44.  The 
first  represents  the  view  of  Mts.  Madison  and  Adams  from  Randolph 
hill,  about  five  miles  from  Gorham  in  the  Moose  River  valley.  In  this 
neighborhood  one  can  study  to  advantage  various  features  about  the 
bases  of  the  mountains,  that  help  make  up  a  perfect  sketch, — the  ragged 
edges  of  ravines,  outlines  of  the  rocky  abutments,  and  the  valleys  made 
by  the  streams  and  clefts  in  the  ledges.  These  forms  are  such  as  are 
peculiar  to  schists.  In  Fig.  44  the  base  seems  broader;  and  now  Mt. 
Washington  has  made  its  appearance  in  a  small  cone  between  and  back 


Fig.  80. — WASHINGTON  RANGE,  FROM  CARROLL. 

of  the  others.     The  summits  lie  in  a  semi-circular  line,  with  reference  to 
each  other. 

Midway  between  Bethlehem  and  the  Fabyan  house  is  a  view  of  the 
Washington  range  in  Carroll,  that  is  much  admired  (Fig.  80).  It  is  from 
a  point  below  the  Twin  Mountain  house,  though  not  far  distant ;  and  one 
has  the  advantage  here  of  seeing  the  range  behind  a  level  foreground 
consisting  of  the  Ammonoosuc  meadows.  The  range  is  of  schist,  while 
the  foreground  rests  upon  granite.  The  view  may  be  compared  with 
that  in  Fig.  25. 


SCENOGRAPIIICAL    GEOLOGY. 


THE  ROUTE  OVER  MADISON,  ADAMS,  AND  JEFFERSON. 

The  rush  of  travel  to  Mt.  Washington  passes  up  either  the  railway  or 
the  carriage-road  from  the  Glen.  Every  one  desires  to  see  these  thor 
oughfares,  and  the  fine  views  attainable  from  them;  and  perhaps  the 
fundamental  idea  of  the  mountains  should  be  first  apprehended  from 
these  directions.  The  great  conveniences  of  these  routes  are  causing 
the  charming  drives  in  other  directions  to  be  forgotten.  Those  who 
have  the  leisure  should  not  fail  to  traverse  the  road  from  Gorham  to 
Jefferson,  on  the  north  side  of  the  mountains,  as  they  will  then  best 
catch  the  spirit  of 
the  hills,  especially 
if  they  should  leave 
all  travelled  routes 
behind,  and  clamber 
over  the  rocks  to 
the  summits  of  the 
rarely  visited  peaks. 
Any  lover  of  moun 
tain  scenery  must 
yearn  to  stand  upon 
the  top  of  Mt.  Ad 
ams,  as  he  gazes  in 
that  direction  from 
the  Tip-top  house.  I  have  a  few  sketches  setting  forth  certain  peculiar 
ities  of  schist  structure,  which  will  also  illustrate  a  way  of  reaching 
Mt.  Washington  over  Mt.  Adams  from  Randolph,  and  may  be  described 
appropriately  here.  Formerly  there  was  a  path  up  Israel's  river,  passing 
over  Mt.  Jefferson,  known  as  the  Lancaster  path,  but  it  is  now  as  little 
frequented  as  the  Davis  bridle-path  to  the  summit  over  Mt.  Crawford. 
They  are  both  so  overgrown  as  to  be  hardly  distinguished  from  the 
surroundings.  The  Lancaster  path,  however,  is  only  partially  the  same 
with  the  one  under  consideration. 

In  Fig.  8 1  is  a  near  view  of  an  immense  cleft  on  the  north  side  of  Mt. 
Adams,  noticeable  also  in  Fig.  77.  This  seems  almost  inaccessible  from 
below.  In  ascending  to  it  there  is  no  unusual  difficulty,  more  than  the

customary  labor  of  threading  the  forests  in  any  direction  among  the 
mountains.  Adjoining  the  streams  there  are  always  obstacles  like  fallen 
trees  and  a  thick  growth  of  alders ;  and,  in  climbing  the  steeper  ascents, 
a  thick  growth  of  moss  conceals  many  deep  chasms  between  blocks  of 
stone; — but  attention  will  prevent  any  serious  calamity.  It  is  no  easy 
task  to  pass  over  the  side  of  the  great  cleft  which  looks  so  smooth. 
That  beautiful  green  short  growth,  which  so  pleasantly  arrests  the  eye 
upon  the  range,  as  everywhere  else,  is  a  nearly  impenetrable  thicket  of 
stubbed  spruces  and  crooked  poplars.  Fortunate  is  the  person  who  can 

emerge  from  it  with 
whole  garments.  In 
the  sketch,  tiny 
streams  are  seen  to 
flow  down  the  upper 
part.  At  the  very 
head  of  this  cleft  is 
a  wall  that  bars  all 
further  progress  in 
that  direction,  as  ex 
hibited  in  Fig.  82. 
This  view  is  seem 
ingly  about  midway 
in  the  gorge,  above 
the  tall  trees.  To 
wards  Randolph 
there  is  a  uniform, 
sharp  slope  to  the 
road.  Above,  the 
walls  tower  perhaps 
1500  feet  immedi 
ately  under  the  head 
of  the  mountain,  which  cannot  be  seen  by  the  climber.  The  edges  are 
more  jagged  than  the  graceful  curves  about  Tuckerman's  ravine,  and  the 
cleft  possesses  more  elements  of  grandeur.  As  this  ravine  was  first 
described  by  Starr  King,  it  seems  proper  to  restore  the  name,  which, 
though  placed  upon  the  county  map,  seems  to  be  generally  forgotten.  It

should  be  Kings  ravine,  and  it  is  described  in  glowing  terms  by  almost 
its  first  explorer  in  the  White  Hills.  It  may  have  been  termed  Adams 
ravine  in  a  few  places  in  this  volume.

_____  jagged  ledges  on  the 

left.    Between,  there 
is  a  grassy  growth 
of  a  few  feet,  pre 
senting  in  the  view 
a  resemblance  to  an 
artificial  road.     Our 
route  has  led  us  up 
the  east  side  of  the 
ravine  to  the  notch 
between    Madison 
and  Adams.     Fig.  84  may  illustrate  a 
portion  of  it  near  the  gateway.     The 
rocks  on  the  right  overhang  the  trav 
eller  with  a  threatening  aspect,  while 
the  slope  on  the  left  is  more  inviting, 
with  a  scanty  growth  of  grass.     The 
fragments  are  coated  over  with  gray 
lichens,  save  along  a  few  lines  where 
rolling  stones  have  plowed  a  furrow. 

Between  Adams  and  Madison  there 
is  a  deep  valley  containing  a  small 
pond  of  water.  On  rising  up  to  the 
side  of  Adams  from  the  gateway,  one  is  surprised  to  see  so  sharp  a  cone 
as  is  presented  by  Mt.  Madison.  (See  Fig.  69.)  With  a  cloud  below, 
and  the  mountain  standing  out  by  itself,  the  effect  is  that  of  an  enor 
mously  high,  sharp  mountain  from  this  point  of  view.  An  easier  way 
of  reaching  Madison  is  to  ascend  either  from  Martin's  Location  (H.  D. 
Copp's),  or  from  the  summit  of  the  northern  Pinkham  Notch  road.  The 
crest  of  the  slope,  if  followed  strictly,  will  bring  one  by  the  shortest  road 
to  the  summit,  from  the  last  mentioned  starting-point,  though  the  spruce

growth  is  fearful  to  traverse.  Ledges  are  common  at  the  summit,  with 
obscure  glacial  markings.  The  strata  are  immensely  contorted  here,  as 
well  as  on  the  ridge  running  towards  the  Half-way  house  on  the  Glen 
carriage-road,  and,  in  fact,  everywhere  over  these  highest  peaks. 

On  coming  back  to  the  Notch  above  Fig.  83  (for  we  have   made  a 
detour  to  Madison),  a  portion  of  Adams  stands  up  very  lawlessly  upon 


CLIFFS   IN   KINGS   RAVINE. 


its  west  side,  and  exerts  a  strange  fascination  over  the  tourist.  The 
rock  is  bleak  and  bare,  as  is  nearly  every  portion  of  these  summits, 
but  gives  the  impression  of  softness.  This  feeling  may  be  due  to  the 
curvatures  in  the  strata.  Ruskin,  in  his  Modern  Painters,  maintains 
that  one  secret  of  Alpine  grandeur  consists  in  the  existence  in  the  nee 
dles  of  infinite  curves,  or  those  that  never  can  return  into  themselves, 
like  the  parabola.  The  principle  may  be  applicable  here,  as  it  certainly 
is  in  many  other  parts  of  the  range. 

Mt.  Adams  does  not,  like  Madison,  present  ledges  upon  its  summit. 
Frost  has  broken  down  the  rocks,  and  fragments  are  strewn  universally 
over  the  cone.  You  can  find  one  comparatively  small  block,  standing 
above  every  other  one,  at  the  very  apex.  Hence  it  is  impossible  to  say 
whether  the  great,  rounding  ice-agency  has  pushed  over  the  summit  of 


SCENOGRAPHICAL    GEOLOGY.  6l/ 

Adams.  It  is  at  the  same  level  with  the  highest  supposed  foreign  peb 
bles  on  Washington,  and  therefore  may  have  never  been  covered  by 
moving  ice. 

Adams  has  a  double  summit,  as  appears  in  Fig.  81.  We  may,  for  con 
venience,  call  the  lesser  one,  which  is  farther  to  the  south,  Mt.  Quincy 
Adams.  It  rises  out  of  a  very  level  space,  perhaps  a  part  of  our  plateau 
described  above.  The  view  from  Adams  is  very  much  the  same  as  from 
Washington,  save  that  we  see  the  highest  of  the  White  Mountains,  which 
cuts  off  the  south-western  view,  as  would  appear  from  Fig.  71.  The 
country  to  the  north  is  also  more  exactly  defined.  In  a  visit  to  Adams, 
made  about  the  first  of  May,  at  the  time  of  our  occupation  of  the  sum 
mit  of  Mt.  Washington  for  meteorological  purposes,  I  found  the  path 
more  comfortable  than  in  summer,  because  snow  filled  up  many  of  the 
lacunae  between  the  rough  blocks.  On  a  subsequent  occasion,  tourists 
visiting  Adams  could  plainly  hear  shouting  upon  Mt.  Washington,  a  dis 
tance  of  four  miles  in  an  air  line. 

The  rest  of  the  route  to  Washington  is  less  exciting  than  up  King's 
ravine,  but  oftentimes  adventurous  and  everywhere  delightful  views  are 
afforded.  Upon  Mt.  Jefferson  is  the  curious  castellated  ridge,  shown  on 
page  28,  and  also  the  Sentinel  (Fig.  76).  The  lowest  part  of  the  notch 
between  Adams  and  Jefferson  has  a  very  narrow  summit,  the  ground 
sloping  steeply  on  both  sides  from  a  mere  line.  The  uniform  gray  tint 
of  the  rocks  on  the  north  flank  of  Jefferson  is  relieved  by  many  pure 
white  blocks  of  quartz.  The  hummocks  of  Mt.  Clay  show  more  reg 
ularity  of  stratification  than  any  of  the  other  peaks,  while  the  slope 
towards  the  gulf  is  precipitous  and  impassable. 

THE  ASCENT  OF  MT.  WASHINGTON. 

The  three  thoroughfares  ascending  Mt.  Washington,  most  commonly 
used  by  tourists,  are  the  Crawford  bridle-path,  the  carriage-road  from 
the  Glen,  and  the  railroad  from  Ammonoosuc  station.  The  latter  will 
very  soon  connect  with  the  Boston,  Concord  &  Montreal  Railroad,  so 
that  one  can  ride  from  Boston  to  the  summit,  with  only  one  change  of 
cars,  in  ten  hours'  time.  The  Davis  bridle-path  from  the  Mt.  Crawford 
house,  the  foot-path  to  Mt.  Pleasant  from  the  Giant's  grave,  the  Lan 
caster  way,  and  the  older  roads  from  the  Glen  and  Fabyan's,  are  now

obsolete.  I  have  marked  some  of  them  upon  the  general  map,  for  their 
historic  interest. 

Ascent  from  the  Notch.  It  is  rumored  that  the  Crawford  path  is  soon 
to  be  made  into  a  carriage-road,  so  that  one  can  pass  directly  from 
the  Glen  to  the  Notch,  over  the  summit,  with  the  same  team.  Such 
an  improvement  would  greatly  enlarge  the  ability  of  tourists  to  explore 
the  mountains.  The  present  bridle-path  starts  from  the  Crawford  house, 
passes  up  a  valley  on  the  north-west  side  of  Mt.  Clinton  to  its  summit, 
thence  over  Mts.  Pleasant  and  Franklin,  on  the  east  side  of  Monroe,  past 
the  Lake  of  the  Clouds,  and  up  the  cone  of  Washington. 

This  path  has  some  advantages.  After  travelling  a  couple  of  miles  in 
a  forest,  one  comes  out  upon  an  open  ridge,  and  can  enjoy  magnificent 
views  the  rest  of  the  way,  especially  of  the  side  ravines  and  of  Mt.  Wash 
ington.  The  absence  of  much  vegetation  makes  the  tops  of  these  moun 
tains  a  natural  pathway.  Cloud  effects  are  better  on  this  route;  and, 
should  the  highest  summits  be  obscured,  one  feels  repaid  for  the  journey 
by  the  glimpses  obtained  on  the  lower  peaks.  Mt.  Pleasant  is  known  by 
its  rounded  summit,  and  greater  elevation  than  the  peaks  on  either  side. 
When  reached  by  this  path,  the  surface  appears  like  a  smooth  field,  slop 
ing  gently  from  the  centre  outwards  in  all  directions.  The  view  north 
easterly  is  a  notable  one.  First  is  the  long,  bare  top  of  Franklin,  with 
the  serpentine  thread  worn  by  the  horses'  feet  running  its  whole  length. 
Next,  the  double,  ragged  peaks  of  Monroe  present  a  wide  contrast.  The 
natural  slope  of  the  strata  north-westerly  can  be  detected  through  all  the 
rubbish  covering  them.  On  the  right  is  another  view  of  the  great  ele 
vated  plateau, — that  part  known  as  Bigelow's  lawn, — overlooking  Oakes's 
gulf.  Washington  towers  far  above  everything  else,  and  displays  to 
advantage  the  excavations  upon  the  west  side,  with  the  ridge  on  which 
the  railway  ascends  to  the  summit. 

One  of  the  heliotypes  represents  the  larger  of  the  Lakes  of  the 
Clouds,  partially  filled  with  ice  (Vol.  II).  These  are  two  small  tarns 
5000  feet  above  the  sea,  the  sources  of  the  Ammonoosuc,  and  in  the 
saddle  between  Monroe  and  Washington.  Alpine  vegetation  borders 
them,  and  they  have  been  chiselled  out  of  the  solid  rock  by  the  drift. 
The  ice-markings  are  plain  in  their  neighborhood  to  the  height  of 
5200  feet. 


SCENOGRAPHICAL    GEOLOGY.  619 

The  Railway.  The  lower  station  of  the  Mt.  Washington  Railway  is 
known  as  "Ammonoosuc,"  and  consists  of  the  necessary  buildings  for 
the  accommodation  of  the  road.  The  station-house  is  on  the  west 
branch  of  the  swift  Ammonoosuc  stream,  which  has  descended  over 
2000  feet  since  leaving  the  Lakes  of  the  Clouds,  about  three  miles  dis 
tant.  The  stream  is  crossed  by  trestle-work  about  fifteen  feet  high ;  and 
the  track  commences  with  the  grade  of  1700  feet  to  the  mile.  Place  the 
end  of  a  ladder  thirty  feet  long  upon  a  fence  ten  feet  high,  and  an 
adequate  idea  of  this  inclination  will  be  exhibited  to  us.  It  does  not 
continue,  however,  beyond  300  feet.  At  three  fourths  of  a  mile  is  the 
first  water-station,  near  the  "  Cold  spring."  The  grade  becomes  steeper 
again  at  the  "Waumbek  junction,"  one  mile  and  eight  rods  distance  from 
and  1242  feet  higher  than  the  starting-point.  The  road  is  straight  thus 
far,  and  forest  trees  of  ordinary  dimensions  have  been  cut  for  its  passage. 
But  now  the  trees  are  smaller ;  the  track  curves ;  and  soon  there  is  a 
small  cut  through  a  ledge.  With  the  top  of  the  trees  the  trestle-work 
known  as  "Jacob's  ladder,"  2800  feet  above  Ammonoosuc,  is  reached.  A 
view  of  this  portion  of  the  road,  with  the  mountain  engine  upon  it,  has 
been  given  opposite  page  82. 

This  trestle-work  is  at  one  point  thirty  feet  high ;  and  the  track  has  an 
elevation  of  more  than  one  in  three  for  300  feet.  The  traveller  has  been 
noticing  the  changes  in  the  shapes  of  the  western  mountains  in  the  as 
cent,  and  has  observed  the  curious  outline  of  the  Lafayette  range  rising 
up  behind  the  Twin  mountains.  On  the  north  he  may  see  the  beautiful 
south-westerly  slope  of  Jefferson,  and  on  the  south  the  several  peaks  along 
the  Crawford  road.  Westerly,  the  views  of  the  valleys  are  charming. 
His  attention  will  now  be  divided  largely  by  the  curious  angular  stones 
and  the  sub-alpine  vegetation  suddenly  brought  under  his  notice.  Should 
the  weather  be  unpropitious,  this  is  the  place  where  the  powerful  winds 
of  the  upper  current  will  begin  to  be  felt,  and  clouds  may  shut  out  every 
bright  prospect.  Not  far  above  Jacob's  ladder  the  ridge  between  Clay 
and  Washington  will  be  reached ;  and  the  traveller  can  look  down  a  thou 
sand  feet  into  the  black  gulf  at  the  head  of  the  west  branch  of  the 
Peabody  river.  The  rest  of  the  ascent  is  comparatively  gradual,  and 
the  distant  views  are  beginning  to  absorb  the  attention.  Something  of 
the  arctic  desolation  of  the  mountain  itself  is  expressed  in  Fig.  10. 


62O  PHYSICAL    GEOGRAPHY. 

The  Summit.  The  buildings  upon  the  summit  arc  quite  numerous. 
There  are  a  large  hotel,  two  railroad  edifices,  the  old  Tip-top  and 
Summit  houses,  and  the  observatory,  besides  two  barns  just  under  the 
crest  on  the  south-east.  The  views  in  different  directions  now  need  to 
be  obtained  from  several  stand-points  about  the  platforms  and  among 
the  buildings.  From  favored  rooms  in  the  hotel  the  sunrise  can  be  seen, 
without  the  necessity  of  leaving  a  comfortable  room.  The  observatory 
is  specially  favored  in  its  situation,  as  the  finest  views  can  be  obtained 
from  indoors.  With  the  severe  arctic  climate  of  this  locality,  one  natu 
rally  seeks  for  physical  comfort  to  the  neglect  of  the  esthetic ;  but  if  both 
can  be  secured,  the  possessor  should  be  doubly  happy. 

Most  people  are  disappointed  in  the  views  from  Mt.  Washington  sum 
mit.  They  reach  the  top  about  noon,  and  remain  one,  two,  or  more  hours 
in  the  middle  of  the  day,  when  there  are  no  shadows.  They  are  bewil 
dered  by  the  vastness  of  the  panorama,  perhaps  insensibly.  It  may  be 
that  there  is  no  one  to  point  out  particular  features  of  beauty.  The 
landscapes  require  considerable  study  to  be  properly  appreciated.  Let 
one  take  a  map  of  New  England,  and  trace  out  all  the  mountains  west  by 
name,  then  in  other  quarters.  Let  him  realize  that  in  one  direction,  one 
hundred  and  fifty  miles  away,  the  minute  spire  of  Mt.  Katahdin  pierces 
the  horizon,  while  opposite  (the  same  distance)  the  remotest  projection  is 
Graylock  in  western  Massachusetts.  Beyond  the  Green  Mountains  are 
the  clearly  defined  Adirondacks ;  on  the  north  the  great  valley  of  the  St. 
Lawrence.  On  the  south-east,  in  a  clear  morning,  he  may,  with  a  glass, 
see  the  ocean  steamers  in  Casco  bay.  With  this  panorama  before  him, 
let  the  observer  carefully  note  all  the  smaller  peaks  and  valleys,  study 
them  out  from  their  locations  on  the  map,  and  he  will  become  greatly 
interested.  Except  by  a  thorough  inspection  of  what  seem  small  areas, 
he  cannot  appreciate  the  immense  number  and  variety  of  objects  visible. 
He  can  spend  a  full  month  in  observing,  and  discover  some  new  feature 
every  day. 

The  atlas  contains  a  plate  showing  in  outline  the  principal  mountains 
and  valleys,  as  seen  in  the  sweep  from  this  summit.  The  foundation 
of  the  sketch  is  a  series  of  drawings  with  a  camera,  so  that  its  accuracy 
can  be  vouched  for.  The  more  distant  points  have  been  exaggerated  a 
little, — otherwise  they  could  not  be  seen.  The  reader  is  referred  to

from  Mt.  Washington.  These  profiles  will  very  materially  aid  any  one 
in  studying  the  topography  of  the  surrounding  country. 

The  most  interesting  features  of  one's  stay  upon  this  summit  are  de 
rived  from  meteorological  sources, — the  sunrise  and  sunset,  shadows  of 
the  mountain  upon  clouds  and  adjacent  ranges,  wonderful  colors,  shapes, 
and  movements  of  clouds,  the  perception  of  the  beginning  and  progress 
of  storms,  hurricanes,  frost-work,  variation  in  temperature  and  humidity, 
fluctuations  in  the  barometer,  conflict  of  winds  and  clouds,  etc.  Sketches 
of  some  of  these  phenomena  have  been  occasionally  presented  in  this

volume,  especially  what  is  peculiar  to  the  winter.  A  heliotype  of  this 
sort  faces  page  104,  illustrating  the  coating  of  the  summit  with  snow-ice 
in  the  winter.  The  first  is  a  copy  of  a  very  distinct  photograph  of  the 
Carter  range  on  the  east,  but  does  not  do  justice  to  the  subject.  The 
other  shows  delicate  frost-work  upon  the  Bourne  monument  and  the 
low  trestle-work  of  the  railway.  Opposite  page  1 1 2  are  four  more  views,

the  party  in  measuring  the  velocity  of  the  wind;  the  Tip-top  house 
when  covered  by  ice;  shrubs  frosted  in  a  somewhat  different  style,  but 
more  delicate;  and  a  look  in  the  direction  of  Winnipiseogee  lake. 

Carriage-Road.  In  starting  from  the  Glen  house,  up  the  carriage-road, 
one  hardly  realizes  he  is  climbing  a  mountain.  The  road  is  cut  through 
the  forest  for  about  three  miles  and  a  half.  At  four  miles  the  Half-way 
house  is  reached,  and  the  rest  of  the  way  leads  over  bare  rocks  above 
trees.  In  Fig.  85  is  represented  the  appearance  of  Adams  and  Madison

SCENOGRAPHICAL    GEOLOGY.  623 

ravines  about  the  White  Mountains,  partly  because  of  the  presence  of 
snow  there  all  through  the  summer.  Its  position,  in  reference  to  the 
main  topographical  features  of  the  mountains,  may  appear  by  referring 
to  Plate  C,  page  338,  to  the  representation  of  the  mountains,  and  the 
general  geological  map  in  the  atlas.  It  rises  directly  below  the  summit  of 
Mt.  Washington,  having  been  excavated  out  of  the  plateau  much  in  the 
manner  of  a  gorge.  The  beginnings  of  the  cleft  may  be  seen  in  the 
heliotype  of  Mt.  Washington  from  the  south-east,  while  the  general 
aspects  of  the  whole  ravine  are  presented  in  Fig.  86.  The  head  is 
nearly  two  hundred  feet  below  the  summit;  and  the  descent  from  the 
plateau  is  dangerous  along  the  most  feasible  route,  and  impossible  most 
of  the  way.  The  innermost  part  of  the  ravine  is  semi-circular,  the  outer 
cliff  rising  directly  a  thousand  feet.  After  receiving  the  waters  flowing 
from  Huntington's  ravine  into  it  from  the  north,  the  gorge  becomes  much 
more  open,  and  is  hardly  to  be  distinguished  from  ordinary  mountain  val 
leys.  Two  small  tarns, — one  known  as  Hermit  lake, — rest  high  up  the 
valley;  and  above  them  innumerable  rivulets  trickle  down  the  cliffs, 
known  as  Raymond's  cataract  and  the  Thousand  streams  in  several  pub 
lished  stereographs.  The  cliffs  are  composed  of  andalusite  slates,  dipping 
at  a  moderate  angle  into  the  mountain  north-westerly. 

Tourists  are  fond  of  imagining  this  and  the  other  deep  ravines  in  the 
state  as  the  product  of  some  tremendous  earthquake  throe.  They  are 
more  easily  explained  by  the  action  of  frost,  gravity,  and  water-power. 
With  the  elevation  of  the  mountains,  there  will  be  naturally  a  few  lines 
of  depression,  which  give  origin  to  streams.  In  the  colder  seasons,  the 
water  freezing  in  the  seams  of  the  rock  will  detach  slabs  and  blocks  of 
stone.  These,  acted  upon  by  streams,  will  eventually  be  changed  to 
gravel  and  sand,  and  be  washed  down  the  mountain,  leaving  fresh  sur 
faces  for  the  renewed  winter  freezing.  In  this  way,  little  by  little,  the 
work  of  excavation  goes  on,  the  deep,  ragged  ravines  notching  the  moun 
tains  where  the  formation  happens  to  be  slaty  and  permeated  with 
numerous  joints. 

The  snow-arch  is  the  feature  which  visitors  delight  to  examine.  The 
violent  winter  winds  blow  immense  quantities  of  snow  from  the  summit 
into  this  ravine,  accumulating,  it  is  said,  to  the  depth  of  hundreds  of  feet. 
The  enormity  of  the  mass  enables  it  to  resist  the  genial  influences  of  the

sun's  heat  for  a  long  time ; — hence  it  may  remain  in  patches,  in  favorable 
seasons,  even  into  September.     Usually  it  is  more  or  less  arched,  owing 

to  the  more  comparatively 
rapid  melting  next  the  riv 
ulets.  Fig.  87  represents 
an  unusual  form,  as  it  ap 
peared  August  28,  1 86 1. 
The  under  surface  is  al 
ways  uneven,  the  irreg 
ularities  resembling  the 
conchoidal  fracture  of 
cannel  coal,  flint,  and  oth 
er  minerals.  In  August, 
1855,  the  snow  was  said 
to  be  294  feet  long,  66 
broad,  and  15  deep,  by 
tape-line  measurement.

White  Mountain  Notch.  The  term  "notch,"  as  used  in  the  Northern 
states,  designates  mountain  passes,  corresponding  to  the  "gaps"  in  the 
Southern  states, — narrow  defiles,  where  a  few  soldiers  may  dispute  the 
passage  of  whole  armies.  Three  of  these  notches  are  spoken  of  in  New 
Hampshire,  viz.,  the  White  Mountain, — sometimes  called  the  Crawford, 
because  of  its  proximity  to  the  hotel  of  that  name, — the  Franconia,  and 
the  Dixville.  The  White  Mountain  Notch  proper  is  only  three  miles 
long,  nearly  straight,  running  somewhat  west  of  north.  The  northern 
end  of  it  is  shown  in  the  heliotype  opposite  page  79,  being  the  view  from 
the  Crawford  house.  A  plain  appears  in  front  of  the  Gate  of  the  Notch, 
formed  by  the  transportation  of  decomposed  granite  down  the  sides  of 
the  steep  hills.  On  the  left  is  a  bare  rock  called  the  "  Elephant's  Head," 
for  obvious  reasons.  Behind  rises  the  elevated  mass  of  Mt.  Webster, 
2000  feet  above  the  Gate,  and  4000  feet  above  the  sea.  Future  tourists

will  see  a  wider  notch  than  that  here  represented,  since  it  has  been  en 
larged  for  the  passage  of  the  Portland  &  Ogdensburg  Railroad.  To  the 
right  is  situated  Mt.  Willard,  seemingly  of  little  consequence;  and  still 
farther  are  the  eastern  slopes  of  Mts.  Field  and  Tom. 

If  we  rise  a  few  hundred  feet  to  the  top  of  Mt.  Willard,  we  shall  get  a 
glimpse  of  the  entire  lower  part  of  the  Notch.  On  referring  to  the  small 
heliotype  taken  from  this  point,  one  can  see  the  lower  portion  of  the 
inclosing  walls,  the  winding  thread  of  the  Saco  river,  and  the  granite 
mountains  back  of  Frankenstein's  cliff,  after  the  turn  of  the  valley  to 
the  south-east.  The  left-hand  slope  is  on  Mt.  Webster,  and  the  right 
is  Mt.  Willey.  A  few  bare  spots  show  where  loose  materials  have  slid 
down  into  the  river;  and  we  directly  overlook  the  famous  Willey  slide. 
Mt.  Willey  is  3000  and  Mt.  Webster  2500  feet  above  the  Willey  house. 
The  other  part  of  this  heliotype  represents  the  house  occupied  by  Mr. 
Willey  in  1826,  before  the  rushing  down  of  the  granite  debris,  in  which 
he  perished  with  his  household.  The  larger  house  to  the  left  has  been 
added  since  1826,  for  the  accommodation  of  travellers.  Only  a  small 
portion  of  Mt.  Willey  appears  behind  the  house.  Fig.  9  shows  an  out 
line  of  the  slide,  as  it  now  appears,  with  the  pile  of  stones  erected  in 
memory  of  the  destroyed  family. 

A  view  of  Mt.  Willard  from  this  point  is  of  extreme  beauty;  and  our 
heliotype, — one  of  the  finest  in  the  series, — is  placed  in  the  next  volume 
for  the  sake  of  illustrating  geological  structure.  The  south  side  of  Mt. 
Willard  is  precipitous,  and  it  occupies  the  whole  valley,  the  stream  flow 
ing  down  from  the  right  of  it.  A  cleft  hollowed  out  of  this  precipice  is 
known  as  the  Eagle's  nest  or  Devil's  den.  Marvellous  stories  have  been 
told  of  it,  as  supernatural  agents  have  been  supposed  to  keep  off  all 
visitors.  But  our  explorers  of  1870,  with  the  use  of  one  hundred  and 
twenty-five  feet  of  rope  let  down  from  the  summit,  discovered  nothing 
mysterious  about  this  locality,  but  would  not  advise  visitors  to  explore  it 
again  without  better  facilities  for  going  and  coming  than  they  enjoyed. 

Below  the  Willey  house  the  valley  turns  south-easterly ;  and  the  helio 
type  opposite  page  192,  taken  from  this  point,  indicates  the  features  of  the 
mountains  better  than  description.  Mt.  Willey  terminates  abruptly  on 
the  south,  and  the  hills  succeeding  are  1500  feet  less  in  height.  Directly 

west  from  the  Willey  house  are  the  remotest  head  waters  of  the  Merri-

mack.  Still  farther  to  the  south,  the  aspect  of  the  Saco  valley  appears 
in  the  heliotype  which  shows  Mt.  Crawford,  over  Dr.  Bemis's  house,  at 
Bemis  station  on  the  railroad.  This  is  the  last  of  the  granite  elevations 
on  the  east  till  Wilkes's  ledge  is  reached,  represented  opposite  page  220, 
in  company  with  a  view  of  Mt.  Pleasant.  The  mountains  on  the  west 
side  are  granitic  throughout,  the  schists  below  Mt.  Crawford  consti 
tuting  an  island. 

We  are  now  prepared  to  understand  the  origin  of  the  Notch.  It  has 
been  excavated  almost  entirely  out  of  granite.  It  lies  near  the  eastern 
border  of  the  vast  sheet  of  Labrador  granites  heretofore  described,  per 
haps  on  the  line  of  eruption.  This  deep  valley  exists  for  the  reason  that 
the  denuding  agents  have  excavated  it  out  of  the  softest  materials  occur 
ring  in  this  vicinity.  The  summits  of  Mts.  Webster  and  Willey  consist 
of  flinty  slates,  which  resist  decomposition  much  more  steadfastly  than 
the  intervening  granite.  A  climb  up  both  these  mountains  shows  that 
the  granite  extends  nearly  to  their  summits.  In  descending,  one  finds  an 
abundance  of  loose,  friable  rocks,  inclined  at  the  greatest  angle  possible 
for  such  materials.  These  fragments  accumulate  gradually  through  the 
action  of  frost,  and,  under  favorable  conditions,  when  rendered  pasty  by 
abundant  rains,  make  a  kind  of  plastic  material  which  slides  to  the  bot 
tom  of  the  valley,  where  the  river  disintegrates  it  still  further,  and  carries 
it  towards  Conway.  The  plains  below  Bartlett  are  largely  composed  of 
the  fragments  brought  down  from  this  narrow  valley.  The  Saco  valley 
below  Mt.  Webster  is  lower,  because  the  walls  are  composed  entirely  of 
this  softer  rock,  and  have  yielded  readily  to  the  forces  of  disintegration. 

The  excavation  of  the  broad  valley  of  the  Ammonoosuc  to  the  west 
of  the  Washington  range,  bounded  northerly  by  Mt.  Deception,  and 
southerly  by  Mts.  Pleasant,  Clinton,  and  Willard,  is  to  be  explained  in 
the  same  way,  only  the  materials  have  gone  down  towards  the  Con 
necticut  instead  of  the  Saco.  The  harder  ridge  remains  on  the  east. 

OTHER  VARIETIES  OF  ROCK  SCULPTURE. 

Of  the  other  shapes  fashioned  by  Nature,  the  isolated,  conical  schis 
tose  mountains  are  the  most  unusual.  Such  are  Monadnock,  Kearsarge, 
Ragged,  and  numerous  smaller  eminences  rarely  heard  of,  like  Peaked 
mountain  in  Piermont.  Their  peculiarity  consists  in  the  rising  up  from 


SCENOGRAPHICAL    GEOLOGY. 


627 


a  plateau  of  older  formations  of  schists  entirely  isolated  from  any  other 
deposits  of  the  same  age,  yet  with  highly  inclined  strata.  These  are, 
unlike  the  sugar-loaf  mountain 
structures,  composed  of  nearly 
horizontal  strata,  which  have 
been  rounded  by  erosion. 
These  elevations,  like  the  lat 
ter,  are  relics  of  a  once  wide 
spread  blanket  of  rock;  but 
the  fragments  have  been  doub 
led  up  by  plicating  forces,  and 
their  former  connection  seems 
difficult  to  believe.  Their  pres 
ent  separation  is  not  due  to 
erosion  alone.  It  is  also  likely 
that  there  have  been  some 
special  uplifts  of  land  in  con 
nection  with  each  of  these 
summits.  In  New  Hampshire 
these  mountains  are  likely  to 
be  confounded  with  those  of 
granitic  origin,  like  the  Strat 
ford  peaks. 

I  do  not  need  to  speak  fur 
ther  of  our  ravines  and  gorges, 
as  the  most  prominent  ones 
have  been  described.  Fig. 
88  may  illustrate  some  of  our 
broad,  sloping  valleys,  where 
level  plateaus  have  been  form 
ed  by  the  transportation  of 
drift  material.  Our  greater 
valleys  of  this  sort  are  too 
extensive  for  representation. 
Such  are  the  Conway  plains, 
the  barren  expanse  in  Madison  and  Ossipee,  and  many  other  districts 


628  PHYSICAL    GEOGRAPHY. 

in  the 'south-east  part  of  the  state  below  the  level  of  the  5oo-feet  con 
tour  line.  Where  the  work  of  transportation  has  been  mainly  effected 
by  water,  the  sand  is  often  left  in  one  district,  while  the  more  fertile 
ingredients  have  been  segregated  from  it,  and  deposited  in  alluvial 
meadows. 

TJic  Ascent  of  Hit.  Carrigain.  This  mountain  being  practically  un 
known  to  tourists,  I  will  reproduce,  from  our  second  annual  report,  a 
brief  sketch  of  its  ascent,  by  Prof.  G.  L.  Vose.  The  results  of  another 
trip  in  1874,  by  G.  F.  Morse,  are  given  graphically  in  the  atlas.  The 
completion  of  the  railroad  through  the  Notch  will  now  bring  this  moun 
tain  into  notice. 

Mt.  Carrigain  stands  almost  exactly  in  the  centre  of  the  vast  group  of  the  White 
and  Franconia  mountains,  and,  rising  as  it  does  to  a  height  of  nearly  5000  feet,  is  a 
marked  feature  in  the  landscape  from  almost  every  point  of  view.  Conversely,  the 
view  from  Carrigain  must  embrace  the  whole  mountain  mass,  and  must  sweep  around 
over  all  the  principal  summits. 

The  morning  was  bright  and  clear,  and  promised  good  weather  for  the  ascent. 
Leaving  our  hotel  directly  after  breakfast,  we  drove  to  Lawrence's  farm,  and,  sending 
back  our  team,  strapped  our  packs  upon  our  backs,  bid  good-by  to  civilization  and  our 
paper  collars,  and  took  to  the  woods,  following  up  the  north  bank  of  Sawyer's  river. 
A  walk  of  a  little  more  than  an  hour  brought  us  to  Duck  Pond  stream,  a  tributary  of 
the  river  from  the  north.  Crossing  this  brook,  we  continued  in  a  north-westerly  direc 
tion  for  an  hour  and  a  half,  when  we  struck  Carrigain  brook,  the  second  tributary  from 
the  mouth  of  Sawyer's  river.  This  brook  has  its  rise  both  upon  Mt.  Carrigain  and  in 
the  deep  notch  east  of  it,  and  thus  leads  by  its  west  fork  directly  to  the  top  of  the 
mountain.  Proceeding  up  the  brook  for  an  hour,  we  stopped  at  the  foot  of  the  ascent, 
which  was  now  directly  in  front  of  us,  to  dine ;  and,  after  a  short  rest,  commenced  the 
climb,  following  the  bed  of  the  stream,  which  tumbles  down  the  steep  eastern  slope  of 
the  mountain. 

The  summit  of  Carrigain  is  4800  feet  above  the  sea ;  the  base  of  the  mountain  is 
probably  about  1200  feet  in  height,  thus  leaving  3600  feet  from  the  summit  to  the  level 
of  Carrigain  brook,  at  least  3000  of  which  is  in  one  almost  unbroken  slope,  so  steep  as 
to  require  the  constant  use  of  both  arms  and  legs  in  its  ascent.  The  west  fork  of  the 
brook  leaps  down  for  a  great  height  over  broad  steps  of  granite  ;  and  this  gigantic 
flight  of  stairs  affords  for  a  considerable  distance  the  best  means  of  ascent.  The  bed 
of  this  brook  we  named  for  our  guide, — who  was  the  first  to  ascend, — Cobb's  Stairs. 
We  kept  the  stream  for  about  1000  feet  of  vertical  ascent,  at  which  point  it  became  so 
abrupt  that  we  were  forced  to  abandon  it  for  the  wooded  slopes,  where  the  foothold 
was  better,  and  the  trees  offered  us  the  assistance  we  needed  for  dragging  up  the  con 
stantly  increasing  weight  of  our  bodies.  The  surface  of  the  magnificent  slope,  up  which 


SCENOGRAPHICAL    GEOLOGY.  629 

we  were  now  toiling,  appears  to  consist  entirely  of  loose  angular  blocks  of  granite, 
dislodged  by  the  frost,  and  covered  with  a  deep  matting  of  rich  green  moss,  in  which 
we  sink  to  the  ankles,  and  through  which  we  not  unfrequently  break  into  some  crevice 
up  to  the  middle.  For  about  two  hours  we  work  doggedly  up  this  apparently  intermin 
able  slope, — keeping  the  brook  always  in  hearing,  in  order  not  to  get  beyond  our  supply 
of  water  for  the  night, — stumbling  now  into  some  hidden  chamber  beneath  the  moss, 
now  lifting  ourselves  up  by  the  friendly  branches  of  spruce  and  pine,  now  sinking 
exhausted  into  the  soft  green  bed  beneath  our  feet,  now  winding  around  some  fallen 
tree,  still  up,  up,  up  we  go,  panting  and  straining,  with  every  muscle  called  into  play 
and  every  drop  of  blood  in  vigorous  motion,  till  the  distant  mountains  begin  to  lift 
their  blue  heads  above  the  decreasing  trees ;  till  exhausted  nature  calls  loudly  for  rest, 
and  the  small  rill  trickling  beneath  our  feet  is  all  that  remains  of  our  brook.  *  * 

Daylight  found  us  ready  for  the  final  pull,  which  should  place  us  on  the  summit  of 
Carrigain.  Despatching  our  breakfast,  and  taking  nothing  but  note-book  and  compass, 
we  move  slowly  up,  threading  our  way  sometimes  on  foot,  sometimes  on  our  hands  and 
knees,  among  the  scrub  spruces,  and  sometimes  upon  the  rough,  gray  blocks  of  granite 
that  strew  the  mountain  side,  till  a  shout  from  the  guide  sends  new  vigor  into  our 
muscles  ;  and  one  more  lusty  pull,  and  a  rough  scramble  through  the  bushes  and  over 
the  rocks,  and  we  stand  upon  a  narrow  ridge,  from  which  the  great  slopes  sweep  down 
in  one  unbroken  descent  to  the  green  carpet  of  forest  spread  out  like  a  map  beneath. 

While  we  had  been  engaged  in  reaching  this  point,  the  clouds  had  not  been  idle. 
Indeed,  they  were  a  little  ahead  of  us ;  and  when  we  "arrived  upon  the  summit,  we 
found  the  mountain  mists  creeping  slowly  in  upon  us,  and  one  by  one  wiping  out  the 
great  ranges  that  surrounded  us.  This  was  not  pleasant ;  but  we  had  come  too  far  to 
give  up  the  view  from  Mt.  Carrigain,  and,  making  a  good  fire,  we  sat  down  and  awaited 
better  times.  Fortunately,  they  were  not  long  coming;  and,  when  we  least  expected 
it,  a  rift  in  the  vapors  showed  the  wide  ring  of  the  distant  horizon,  and  the  surging 
swell  of  the  vast  landscape  around  us. 

Directly  opposite  to  Mt.  Carrigain  upon  the  east  rises  a  noble  summit,  scarred  with 
tremendous  slides,  and  forming  with  Carrigain  a  notch  not  inferior  in  depth  or  abrupt 
ness  to  the  White  Mountain  Notch  itself.  [See  view  of  Carrigain  Notch,  p.  596.] 
This  fine  summit  we  named  Mt.  Lowell,  in  honor  of  one  of  the  oldest  and  most  enthu 
siastic  among  White  Mountain  explorers, — Abner  Lowell,  Esq.,  of  Portland.  The 
slopes  of  these  two  mountains  in  Carrigain  Notch  are  more  imposing,  both  on  account 
of  their  exceeding  steepness  and  of  their  great  height,  than  any  others  yet  described 
in  the  White  Mountains.  The  distant  view,  too,  in  every  direction,  is  full  of  interest. 
Ranges  and  notches,  huge  mountains  and  broad  valleys,  never  seen  from  the  points 
commonly  visited  in  this  region,  are  spread  all  around.  From  its  central  position  a 
better  idea  of  the  arrangement  of  the  White  and  Franconia  mountains  is  had  than 
from  any  other  point,  perhaps,  in  the  whole  group.  To  the  east  we  see  Washington, 
Monroe,  Franklin,  Pleasant,  Clinton,  Jackson,  Webster,  Resolution,  Giant's  Stairs, 
Crawford,  the  Carter  mountains,  Doublehead,  Pequawket,  and  the  lower  summits  of

Jackson,  Chatham,  and  Bartlett ;  to  the  south-east  and  south,  the  Mote,  Chocorua, 
Tremont,  Table  mountain,  Passaconnaway,  Whiteface,  Squam,  and  Tripyramid ;  while 
to  the  west  and  north-west  lie  the  Franconia  and  Twin  mountains,  and  the  great 
mass  of  ridges  and  valleys  between  the  Saco  and  the  Pemigewasset.  The  view  from 
Carrigain  opens  new  fields  in  every  direction  for  mountain  exploration ;  and  it  is  to  be 
hoped  that  the  many  persons  frequenting  the  mountains,  and  fond  of  rough  tramps, 
will  ere  long  penetrate  these  interior  recesses  of  the  wilderness,  and  acquaint  us  with 
the  topography  and  geology  of  this  now  unknown  part  of  the  White  Mountain  group. 

CASCADES. 

Cascades  and  waterfalls  occur  abundantly  in  New  Hampshire,  and 

they  nearly  always  display  the  prevail 
ing  ledges  of  the  vicinity,  and  conse 
quently  are  sought  for  in  geological 
explorations.  I  will  mention  only  those 
which  are  figured,  for  their  name  is  le 
gion. 

Georgianna  falls  in  Lincoln  (Fig.  41, 
p.  215)  is  one  of  the  grandest  cascades 
to  be  found  among  the  mountains.     It 
is  more  than  a  mile  west  of  the  Pemi 
gewasset  valley,  upon  a  tributary  com 
ing  out  of  Bog  pond.     The  path  leads 
through  the  woods  from  a  farm-house 
about   two   miles  below   the   entrance 
to  the  Flume.     For  more  than  a  mile 
there  is  a  series  of  smaller  cascades  till 
the  main  fall  is  reached. 
This     consists    of    two 
leaps  of  eighty  feet  each, 
which    give    the    effect 
of  a  single  fall,  as  seen 
through  the  trees  from  a 
distance.     An  extensive 
cut  has  been  made  in  the 
rocks,  which  are  largely

Ripley's  falls  (Fig.  43,  p.  226)  are  situated  upon  a  brook  near  the 
Willey  slide,  and  about  two  miles  back  from  the  Saco.  The  water  leaps 
first  over  four  stair-like  ledges, — each  about  six  feet  high,  which  are  not 
represented  in  the  figure, — and  then  slides  down  a  granite  flume  one 
hundred  and  fifty  feet  long,  at  an  angle  of  forty-five  degrees,  ending  in 
a  large  pool.  The  water  is  seventy-five  feet  wide  at  the  base,  and  fifty 
at  the  summit.  Still  higher  up  the  stream  are  two  other  falls,  called  the 
"Sparkling  cascade"  and  the  "Sylvan  Glade  cataract."  There  is  a  yet 
finer  waterfall  upon  Bemis  brook,  about  four  miles  farther  down  the 
Saco,  upon  the  same  side  of  the  valley. 

In  the  White  Mountain  Notch,  rather  more  than  a  mile  from  the  Craw 
ford  house,  are  the  Flume  and  Silver  cascades.  The  latter  is  figured  best 
in  the  text  adjoining,  and  the 
lower  portion  more  particu 
larly  in  a  heliotype  in  Vol.  II. 
It  can  be  seen  from  the  road, 
as  it  descends,  for  over  three 
hundred  feet.  The  fall  is  part 
ly  precipitous,  but  mostly  at 
a  comparatively  small  angle.  / 
The  water  flashes  in  the  sun 
light  like  silver:  hence  the 


name.  In  a  very  dry  season 
it  almost  disappears  from  view. 

In  Fig.  90  is  an  outline  of 
Cuba  falls,  on  the  east  side 
of  Mt.  Cuba  in  Orford.  They 
were  first  brought  to  notice 
by  the  photographs  of  A.  F. 
Clough,  but  are  in  a  remote 
region  rarely  visited  by  tour 
ists.  It  is  unusual  to  see  so 
great  a  fall  of  water  leaving  a 
clear  space  behind,  as  in  this 
instance. 

Opposite  page  184  is  a  heliotype  of  the  Crystal  cascade.     It  is  about

632  PHYSICAL    GEOGRAPHY. 

three  miles  south  of  the  Glen  house,  near  the  height  of  land  between 
Jackson  and  Gorham,  and  upon  Ellis  river.  The  water  flows  from  Tuck- 
erman's  ravine.  The  view  takes  in  about  eighty  feet  of  descent  over 
slaty  rocks  crossed  by  igneous  dikes.  The  view  is  taken  from  a  high 
bank  opposite  the  fall.  The  water  is  much  spread  out  in  this  cascade, 
and,  as  the  supply  diminishes,  is  divided  into  several  threads  or  frills. 

The  Glen  Ellis  falls  are  a  mile  farther  south,  and  upon  the  same 
stream.  These  are  a  little  higher  than  the  one  just  mentioned.  One 
is  best  impressed  by  their  grandeur  if  he  rests  against  a  tree  overhang 
ing  the  precipice  above  the  fall.  The  water  is  much  more  confined  in 
its  flow  than  at  the  Crystal  cascade,  and  is  more  constant  in  its  shape 
through  both  wet  and  dry  seasons. 

The  view  of  the  Jackson  falls  is  placed  opposite  page  256.  The  rock 
here,  and  at  the  Goodrich  falls  lower  down,  represented  in  Vol.  II,  con 
sists  of  slightly  inclined  sheets  of  granite.  They  are  upon  the  Ellis 
river. 

Opposite  page  310  is  a  representation  of  Berlin  falls  in  the  Andros- 
coggin  river.  As  this  stream  is  fed  from  the  large  lakes  in  north-western 
Maine,  the  supply  is  always  large  and  constant.  The  descent  is  mostly 
a  rapid  rather  than  a  cascade,  amounting  to  nearly  t\vo  hundred  feet  in 
the  course  of  a  mile.  The  gorge  is  nearly  twenty  feet  deep,  excavated 
through  dark  schists ;  and,  by  standing  upon  a  bridge  thrown  across  the 
river,  one  can  best  watch  the  mad  descent  of  the  river,  from  the  smooth 
satin  aspect  to  a  "foam  foliage,  white  and  prismatic,  cresting  the  leaping 
waves,  and  running  from  fall  to  fall."  Early  in  the  summer,  logs  are  con 
stantly  passing  through  this  narrow  passage.  These  falls  are  close  to 
the  carriage-road,  about  six  miles  above  Gorham. 

Walker's  falls,  over  granite  sheets  in  Franconia,  and  Beecher's  cascade, 
a  little  west  of  the  Crawford  house,  are  placed  upon  the  same  heliotype, 
opposite  page  305.  The  joints  are  less  easily  recognized  in  the  latter 
example.  The  Emerald  pool,  opposite  page  232,  is  one  of  the  resting- 
places  for  the  active  water  in  the  midst  of  so  much  tumbling.  It  is  just 
above  Thompson's  falls,  and  near  the  Glen  house.  In  Diana's  Bath, 
North  Conway,  opposite  page  272,  one  sees  a  basin  about  ten  feet  deep, 
into  which  water  passes  from  over  a  sheet  of  granite.  It  is  near  the 
"Cathedral."

LIST  OF  ILLUSTRATIONS  OF  SCENERY. 

The  following  is  a  list  of  the  illustrations,  selected  to  set  forth  the

CHAPTER    XIX. 


SCENERY     OF     COOS      COUNTY. 


BY  J.    H.    HUNTINGTON. 


HETHER  we  stand  upon  the  summit  of  one  of  our  highest  moun 
tains  in  winter,  when  there  is  embraced  in  the  view  the  whole 
country  from  the  ocean  to  the  Adirondacks,  or,  in  summer,  we  stand  by 
the  side  of  one  of  our  quiet  lakes,  which  is  entirely  encircled  by  lofty 
hills,  while  the  blue  dome  of  the  sky  seems  to  rest  just  on  the  hill-tops, 
there  is  a  charm  and  enchantment  in  the  scene  that  draws  the  mind 
away  from  things  terrestrial,  and  bears  it  away  into  the  realm  of  thought 
and  fancy.  From  the  mountain  summits,  the  clouds  that  lie  along  the 
western  horizon  in  such  brilliant  relief  against  a  darker  background 
become  a  celestial  city,  with  towers  and  spandrels  of  gold ;  the  lake  and 
its  immediate  surroundings,  shut  out  from  all  the  world,  become  a  par 
adise.  The  mountain  summit  in  mid-winter,  and  the  placid  lake  in 
summer,  nestling  among  the  hills,  are  the  extremes.  The  first  embraces 
all  that  is  grand  and  sublime.  The  view  is  circumscribed  only  by  the 
distant  horizon;  and  the  storms  of  mid-ocean  pale  before  the  blasts  of 
the  upper  currents  of  the  air.  The  outlook,  with  its  ever-varying  scene 
of  clouds,  and  the  storms  sweeping  along  with  such  terrific  grandeur, 
arouse  the  whole  being.  Instead  of  fear  and  terror,  the  mind  grasps 
the  whole  as  a  grand  and  terrific  display  of  the  power  that  has  fixed  a 
limit  even  to  these  manifestations. 


SCENERY    OF    COOS    COUNTY.  637 

On  the  other  hand,  when  in  early  summer  there  is  a  dreamy  stillness 
in  the  air,  and  the  foliage  on  tree  and  shrub  has  the  freshness  of  spring, 
the  placid  lake,  of  all  places  else,  soothes  and  brings  a  calm  quiet  to  the 
mind ;  and,  as  a  drowsy  forgetfulness  of  things  objective  comes  over  us, 
and  we  are  wafted  away  to  indulge  in  such  delicious  reveries,  then,  when 
again  we  are  conscious  that  this  physical  frame  languishes  unless  it  is 
nourished  by  something  more  substantial  than  dreams,  we  regret  the 
condition  of  our  physical  existence,  and  almost  wish  that  life  itself  were 
a  dream. 

To  point  out  places  of  interest,  where  those  who  have  a  love  for  the 
grand  and  the  beautiful  can  feast  and  be  filled,  rather  than  to  describe 
the  scenery,  will  be  our  object  in  the  following  pages. 

If  a  person  delights  in  primeval  forests,  he  will  certainly  be  charmed 
with  the  northern  part  of  New  Hampshire.  A  journey  of  a  day  and  a 
half  from  Connecticut  lake,  through  an  unbroken  forest,  will  take  a  per 
son  to  Crown  monument,  which  is  at  the  extreme  north-east  corner  of 
the  state.  It  is  on  the  water-shed  between  the  waters  of  the  St.  Law 
rence  and  the  streams  running  south  into  the  Atlantic,  and  it  is  so  called 
because  a  monument  was  placed  there  by  the  commissioners  who  estab 
lished  the  boundary  between  the  states  and  the  provinces.  From  a  ridge 
of  land  2568  feet  above  the  level  of  the  sea,  where,  looking  northward, 
the  land  slopes  towards  the  St.  Lawrence,  and  southward,  towards  the 
Atlantic,  the  view  must  be  extensive.  In  either  direction  we  look  over 
only  illimitable  forests,  except  that  in  the  dim  distance,  a  little  to  the  east 
of  north,  there  is  a  small  settlement,  probably  at  the  north  end  of  Me- 
gantic  lake, — otherwise  the  view  embraces  a  boundless  forest.  Immedi 
ately  north,  the  slope  is  quite  gradual,  and,  as  it  stretches  northward,  the 
country  seems  like  a  plain  extending  to  the  horizon.  To  the  north-east 
is  Saddle  mountain,  with  hills  and  ridges ;  to  the  north-west,  Megantic 
mountain  rises  as  from  an  immense  plain.  Embraced  in  the  view  north 
ward  are  the  head  waters  of  the  St.  Francis  and  Chaudiere  rivers,  while 
east  and  west  is  the  high  ridge  that  forms  the  water-shed.  The  view 
directly  south  is  limited,  for  a  mountain  ridge  runs  from  the  Magallo- 
way  directly  west  into  New  Hampshire.  To  the  south-west,  the  high 
ridge  that  encircles  the  basin  where  the  many  branches  of  the  Magallo- 
way  have  their  source,  obstructs  the  view  in  that  direction.  To  the 


638  PHYSICAL    GEOGRAPHY. 

south-east  there  is  nothing,  as  far  as  the  eye  can  see,  but  high  ridges 
and  mountain  peaks,  which  follow  each  other  in  rapid  succession  until 
in  the  far  distance  they  seem  to  pierce  the  sky. 

If  we  should  follow  along  the  boundary  between  New  Hampshire  and 
Quebec  province,  there  would  be  many  points  where  we  should  wish  to 
stop  and  view  the  grand  panorama  spread  out  before  us.  Two  of  the 
most  remarkable  outlooks  we  will  notice.  Not  far  from  three  and  a  half 
miles  south-west  from  Crown  monument  there  is  a  high  point  of  land. 
If  it  was  isolated  from  the  ridge  that  extends  in  either  direction  from  its 
summit,  it  would  be  a  mountain  of  quite  respectable  proportions.  Its 
height, — 2812  feet, — would  place  it  among  the  mountains.  The  distant 
view  is  not  unlike  that  from  Crown  monument,  but  the  immediate  sur 
roundings  are  much  more  grand;  and  chief  among  the  attractions  is  a 
mountain  lake,  which  lies  in  a  depression  to  the  west  eight  hundred  feet 
below  the  summit,  and  it  is  so  near  that  we  seem  to  look  directly  down 
upon  it.  Another  point  of  interest  on  the  boundary  is  in  the  vicinity  of 
Third  lake.  The  view  northward  embraces  a  continuous  forest,  extend 
ing  fifty  miles  or  more ;  and  in  the  distance,  Megantic  mountain  stands 
massive  and  alone.  One  or  two  houses  in  Ditton  are  the  only  habita 
tions  that  can  be  seen. 

South,  half  a  mile  distant,  we  look  down  on  Third  lake.  On  a  clear, 
bright  day  in  early  summer,  when  the  stately  forests  are  reflected  in  its 
waters,  undisturbed  by  a  single  ripple,  it  presents  a  scene  of  quiet  beauty 
that  cannot  be  surpassed.  Generally,  the  view  southward  is  not  exten 
sive,  but  on  some  of  the  higher  points  we  can  overlook  the  nearer  hills, 
and  in  the  distance  some  of  the  peaks  of  the  White  Mountains  can  be 

seen. 

MT.  CARMEL. 

Mt.  Carmel  rises  3711  feet  above  the  level  of  the  sea.  It  is  on  the 
line  of  New  Hampshire  and  Maine,  as  the  state  line  crosses  it  just  as  it 
begins  to  slope  towards  the  west.  The  mountain  consists  of  a  long  ridge, 
and,  from  the  west,  the  ascent  is  quite  gradual.  On  the  ridge  there  are 
two  points  of  nearly  equal  height,  half  or  three  quarters  of  a  mile  apart ; 
from  the  point  east  there  is  a  gradual  slope  for  half  a  mile,  and  then 
the  descent  is  almost  perpendicular  down  to  the  debris  formed  from  the 
fallen  rocks.  Before  we  reach  this  precipitous  height,  there  is  a  ridge 


SCENERY    OF    COOS    COUNTY.  639 

that  branches  off  and  runs  towards  the  north-east;  and  everywhere  along 
the  east  side  of  this  there  are  perpendicular  walls  of  rock.  As  Mt.  Car- 
mel  is  somewhat  isolated,  the  view  from  the  summit  is  extensive. 

Immediately  northward  is  the  great  basin  where  rise  the  many  streams 
that  unite  to  form  the  Magalloway.  Beyond  is  the  ridge  that  forms  the 
boundary  between  the  states  and  the  provinces,  and  through  gaps  in  this 
we  can  see  now  and  then  a  peak  far  to  the  north-east.  To  the  east  the 
view  is  very  fine,  while  near  at  hand  you  look  down  into  the  valley  of  the 
Magalloway.  Here  you  catch  glimpses  of  the  stream,  and  there  you  see 
one  of  the  numerous  lakes  of  this  broad  valley,  for  along  this  river  there 
is  scarcely  a  mile  but  that  has  its  lake  or  bog.  Save  here  and  there, 
where  the  water  reflects  the  bright  sunlight,  the  whole  valley  is  a  dark 
forest  of  evergreen.  Standing  on  the  summit  of  Mt.  Carmel  in  the 
afternoon,  when  the  sun  shines  brightly,  it  is  a  grand  scene  to  watch  the 
shadows  of  the  clouds  as  they  fly  across  the  valley, — they  seem  so 
etherial,  yet  so  much  like  a  thing  of  life.  For  displays  of  this  kind,  I 
know  not  any  place  where  the  effect  is  half  so  grand.  Eastward,  we  can 
see  far  beyond  the  valley,  and  such  an  array  of  hills,  ridges,  and  mountain 
peaks  is  rarely  seen.  Here  is  a  mountain,  irregular  in  outline  and  broken 
abruptly  off;  there  are  two  similar  in  shape,  while  beyond  and  farther 
south  is  a  mountain  summit  that  has  a  graceful  contour  in  its  sweep 
ing  outline. 

"And,  glimmering  through  the  sun-haze  warm, 

Far  as  the  eye  could  roam, 
Dark  billows  of  an  earthquake  storm 

Beflecked  with  clouds  like  foam, 
Their  vales  in  misty  shadows  deep, 

Their  rugged  peaks  in  shine, 
I  saw  the  mountain  ranges  sweep 

The  horizon's  eastern  line." 

Southward,  we  look  down  the  Magalloway,  and  for  twenty  miles  in  a 
direct  line  the  view  is  unobstructed ;  then,  from  the  east,  Mt.  Agizcoos, 
with  its  bare  summit,  extends  partly  across  the  valley.  Looking  still 
southward  in  the  far  distance,  sixty-five  miles  from  the  point  where  we 
stand,  we  see  the  White  Mountains,  in  dim  yet  perfect  outline.  In  some 
respects  the  view  to  the  west  and  south-west  is  the  most  interesting.  In 


640  PHYSICAL    GEOGRAPHY. 

this  direction  there  is  a  succession  of  undulating  ridges  and  hills,  which, 
with  their  shadows  and  ever-changing  color,  give  a  peculiar  charm  to  the 
scene ; — then,  in  the  midst  of  the  forests,  those  sheets  of  water  that  we 
can  see  are  the  Connecticut  lakes.  There  is  probably  not  another  moun 
tain  peak  in  New  Hampshire,  so  high  as  this,  where  one  feels  as  though 
he  was  so  entirely  away  from  the  habitations  of  men.  In  every  direction, 
except  a  single  spot  at  the  outlet  of  Connecticut  lake,  which  is  fifteen  or 
twenty  miles  distant  by  the  shortest  route,  the  whole  country,  embracing 
thousands  of  square  miles,  is  one  vast  wilderness. 

From  the  summit  of  Magalloway  mountain,  three  miles  east  from 
Connecticut  lake,  there  is  a  fine  view  of  mountains,  hills,  and  lakes.  It 
is  especially  fine  in  autumn,  after  the  forests  of  deciduous  trees  have  put 
on  their  robes  of  beauty, — crimson,  scarlet,  and  gold.  The  lakes  which 
form  such  a  marked  feature  in  the  scenery  are  noticed  on  page  223. 

CASCADES. 

Cascades  are  not  very  numerous  in  the  northern  .part  of  Coos  county, 
but  there  are  two  or  three  that  deserve  to  be  mentioned.  On  one  of  the 
western  branches  of  Indian  stream,  near  the  north  line  of  the  Colebrook 
Academy  grant,  there  is  a  cascade  which,  on  account  of  its  rare  beauty, 
deserves  especial  notice.  It  is  in  a  deep  ravine,  and  on  either  side  there 
is  a  dense  forest  of  evergreens.  Here  the  extreme  heat  of  summer  is 
unknown,  for  the  cool  breath  from  the  water  always  tempers  the  atmos 
phere,  and  produces  a  delicious  coolness  that  is  so  grateful  in  summer. 
The  cascade  has  a  height  of  forty  feet ; — the  first  twelve  feet  the  water  is 
broken  by  jutting  rocks;  for  the  remaining  twenty-eight  it  flows  over  a 
ledge,  which  has  a  descent  of  sixty  degrees.  At  the  top  the  stream  is  four 
feet  wide,  but  it  spreads  out  so  that  at  the  base  it  is  twenty  feet.  As  the 
water  runs  across  the  strata,  the  effect  is  very  fine.  The  pure  water,  the 
white  spray,  the  dark,  moss-covered  rocks,  the  cool,  delicious  atmosphere, 
the  shimmering  light  through  the  trees,  the  mossy  banks  of  the  stream, 
the  perfect  stillness  save  the  music  of  the  waters  and  the  songs  of  birds, 
form  a  combination  of  attractions  rarely  found. 

East  from  Connecticut  lake,  and  south-east  from  the  summit  of  Magal 
loway  mountain,  the  Little  Diamond  falls  in  a  series  of  rapid,  wild  cas 
cades.  The  rapids  extend  for  half  a  mile ;  and  the  fall  in  that  distance 


SCENERY    OF    COOS    COUNTY.  64! 

is  one  hundred  and  fifty  feet.  Besides  the  general  rapids,  there  are  per 
pendicular  falls  of  from  three  to  ten  feet.  South-west  of  the  same 
mountain  there  is  a  fall  on  Huggins's  Branch.  For  half  a  mile  there  are 
rapids,  before  we  come  to  the  falls ;  then  there  is  a  slope  of  fifty  degrees 
and  a  fall  of  fifteen  feet;  then  there  is  a  fall  twelve  feet  perpendicular; 
then  there  is  a  slope  of  forty-two  degrees  and  a  fall  of  about  forty  feet, 
confined  between  nearly  perpendicular  strata  of  rock,  and  water  is  thrown 
in  spray  against  the  wall;  and  finally  it  rests  in  a  great  basin  at  the  base. 
A  few  rods  below,  the  stream  turns  to  the  east,  and  has  another  fall  of 
ten  feet.  Altogether,  it  is  a  beautiful  cascade,  and  well  worthy  of  a  visit. 

DIXVILLE  NOTCH. 

Dixville  Notch  is  regarded  by  many  as  one  of  the  most  remarkable 
exhibitions  of  natural  scenery  in  the  state,  perhaps  even  surpassing  the 
famous  Notch  of  the  White  Mountains  in  picturesque  grandeur.  The 
angular  and  precipitous  appearance  of  the  rocks,  rising  hundreds  of  feet 
almost  perpendicular  on  either  side,  is  strikingly  different  from  the 
rounded  and  water-worn  appearance  of  most  of  the  crystalline  rocks 
throughout  the  northern  part  of  the  United  States,  and  seems  to  come 
nearer  to  the  scenery  of  the  Alps  than  anything  else  in  New  England. 
This  Notch  is  easy  of  access,  being  only  ten  miles  from  Colebrook  vil 
lage  ;  and  although  the  highest  point  in  the  road  through  the  Notch  is 
830  feet  above  that  village,  yet  the  ascent  is  so  gradual  that  few  would 
believe  they  had  reached  so  great  an  elevation.  Approaching  the  Notch 
from  the  west,  the  road  passes  through  a  forest  which  in  summer  en 
tirely  obstructs  the  view,  and  the  slow  progress  we  are  able  to  make 
causes  now,  for  the  first  time  in  our  journey,  a  sense  of  weariness.  It  is 
only  for  a  very  brief  space,  however,  for  scarcely  have  we  time  to  com 
plain  before  we  reach  an  opening  in  the  woods,  and  the  grand  view  pre 
sented  in  the  heliotype  bursts  suddenly  upon  us. 

It  surpasses  most  other  notches  in  the  vertical  height  of  its  walls,  one 
point  being  560  feet  above  the  highest  part  of  the  road.  Some  of  the 
highest  precipitous  masses  stand  out  in  bold  relief  from  the  sides.  Table 
rock, — shown  on  the  right  in  the  heliotype, — projects  167  feet,  while  the 
ragged  serrated  edges  everywhere  form  projecting  points.  One  can 
easily  imagine  that  he  sees  here  the  turrets  and  spires  of  some  ruined

cathedral,  or  the  battlements  and  towers  of  castles  of  the  medieval  age; 
or,  as  one  stands  on  Table  rock,  he  can  imagine  that  a  bridge  once 
spanned  the  chasm  below,  and  that  these  masses  of  rock  standing  in 
the  debris  are  the  ruins  of  piers  on  which  it  might  have  been  built  The 
rock  here  differs  in  cleavage  from  that  of  similar  composition  elsewhere 
in  New  Hampshire.  It  splits  in  huge  longitudinal  fragments ;  and  Na 
ture  has  here  quarried  posts  that  equal  in  just  proportion  those  wrought 
by  human  hands. 

On  Table  rock  the  view  embraces  a  wide  sweep  of  country.  We  can 
see  quite  a  distance  into  Maine,  we  can  look  over  a  part  of  Vermont, 
and  it  is  said  that,  when  clear,  places  in  Quebec  province  can  be  recog 
nized  ;  and  from  Table  rock  the  view  down  through  the  Notch  is  always 
grand.  After  passing  the  height  of  the  Notch,  going  east  on  the  right, 
we  can  see  a  profile, — "The  Old  Man  of  Dixville," — which  has  very  fair 
proportions.  On  the  left,  still  farther  east,  there  is  an  excellent  repre 
sentation  of  the  walls  and  turrets  of  a  ruined  castle. 

The  "Flume"  shows  itself  on  the  north  side  of  the  road,  thirty  or  forty 
rods  back  in  the  forest.  It  is  a  chasm,  in  granite,  about  fifteen  feet  wide 
and  fifteen  rods  long;  and  the  stream  running  through  it  falls  about 
thirty  feet  in  cascades.  In  one  place  there  is  a  pot-hole  seven  feet  deep, 
with  a  diameter  of  four  feet.  The  granite  is  divided  by  two  vertical  sets 
of  seams  or  joints,  so  that  large  columnar  blocks  could  be  taken  out 
without  quarrying.  The  excavated  rock  seems  to  have  been  a  trap  dyke, 
part  of  which  may  still  be  seen.  Nearly  opposite  the  Flume,  but  farther 
down  the  valley,  is  Cascade  brook,  a  branch  of  Clear  stream.  Upon  this 
may  be  seen  a  series  of  cascades  for  more  than  half  a  mile.  They  were 
named  Huntington  cascades  by  the  New  Hampshire  Press  Association. 
The  top  of  the  most  interesting  cascade  is  274  feet  above  its  base.  Here 
the  stream  is  divided  by  a  trap  dyke  two  feet  wide ;  and  the  water  falls 
on  each  side  a  distance  of  forty  feet.  The  rock  here  is  the  same  argilla 
ceous  schist  as  in  the  Notch ;  besides,  there  is  an  interesting  trap  dyke, 
containing  glassy  feldspar  and  basaltic  hornblende,  which,  Dr.  Jackson 
says,  resembles  more  a  volcanic  rock  than  any  other  found  in  the  state. 
Most  other  notches  we  can  see  a  long  distance  before  we  reach  them,  but 
here  we  have  scarcely  any  intimation  that  there  is  such  a  vast  rent  in 
the  mountain  until  we  are  almost  in  the  very  gap  itself. 


SCENERY    OF    COOS    COUNTY.  643 

How  was  this  Notch  formed?  is  a  question  that  is  naturally  asked, 
since  it  is  so  unlike  all  others.  There  is  no  theory  so  universally  accepted 
as  that  there  has  been  a  time  when  the  oscillations  of  the  continent  were 
considerable;  that  it  was  once  submerged,  so  that  at  least  quite  a  large 
part  of  New  England  was  beneath  the  ocean ;  then,  again,  it  was  uplifted. 
That  there  have  been  two  of  these  upliftings  and  depressions  is  quite 
certain. 

The  rock  at  Dixville  Notch  is  very  fragile,  and  there  are  reasons  to 
believe  that  a  fissure  in  the  rocks  here  was  originally  produced  by  the 
uplifting  of  the  whole  rocky  strata  of  the  country,  and  that  afterwards  it 
was  worn  out  by  water  and  ice,  perhaps  a  glacier.  The  principal  reason 
for  supposing  a  fissure,  caused  by  uplifting,  to  have  been  the  origin  of 
the  Notch,  is,  that  in  the  rocks,  several  rods  back  from  the  edge  of  the 
Notch,  there  is  now  a  fissure  of  unknown  depth  running  parallel  with  the 
Notch,  and  consequently  across  the  strike.  It  is  well  known  that  when 
great  masses  of  rock  are  removed,  the  underlying  strata  contract  and  pro 
duce  fissures.  It  is  possible  that  this  may  have  been  the  case  at  Dixville, 
since  the  mountain  ridge  is  lower  at  the  Notch  than  it  is  for  several  miles 
on  either  side.  If  at  any  point  in  the  lowest  part  of  the  Notch  we  were 
able  to  find  the  strata  standing  vertically,  as  on  the  sides,  we  might  sup 
pose  the  Notch  was  originally  produced  by  other  causes.  That  ice  did 
something  after  the  fissure  was  formed,  is  evident  from  the  fact  that  in  the 
Notch  and  on  the  east  side  there  are  boulders  that  came  from  the  west ; — 
consequently  they  must  have  been  carried  into  and  through  the  Notch. 

In  Errol  there  is  one  of  the  grandest  outlooks  in  New  Hampshire,  but, 
being  off  from  any  route  of  travel,  it  is  scarcely  known  except  to  those 
who  live  in  the  vicinity,  and  to  the  fortunate  few  who  have  enjoyed  the 
prospect.  Here,  we  are  not  obliged  to  travel  a  long  distance  through  the 
forests,  neither  have  we  to  climb  mountain  summits,  but  on  a  travelled 
road  we  can  sit  in  our  carriage  and  overlook  miles  of  forests,  and  in  the 
distance  see  the  grandest  of  our  mountain  summits.  On  the  road  from 
Errol  Dam  to  Upton,  Me.,  after  crossing  the  Androscoggin,  the  road 
winds  along  and  over  the  ridge  of  land  between  that  river  and  Umbagog 
lake.  As  we  ascend  the  hill,  the  grandeur  of  the  scenery  begins  to 
unfold  itself.  On  our  right,  and  a  little  south  of  west,  is  the  Andros- 


644  PHYSICAL    GEOGRAPHY. 

coggin,  which  pours  along-  over  rapids  until  it  rests  in  a  quiet  bay,  where 
the  river  widens  to  receive  the  waters  of  Clear  stream.  After  leaving 
the  bay  the  river  becomes  rapid  again,  and  pours  along  between  the  hills, 
and  soon  is  lost  to  sight.  Westward,  among  the  hills,  is  Aker's  pond, 
and,  following  up  the  valley  of  Clear  stream,  the  view  is  limited  by  the 
high  ridge  running  through  Dixville.  A  little  farther  south  we  look  over 
the  hills  in  Errol  and  Millsfield,  and  we  can  see  a  few  peaks  in  Odell.  To 
the  south-west  the  forests  stretch  as  far  as  the  eye  can  reach ;  for  nearly 
thirty  miles  there  is  one  unbroken  wilderness.  For  a  distant  view,  I 
know  not  where  the  White  Mountains  can  be  seen  to  such  advantage  as 
just  south  of  the  height  of  land;  neither  do  I  know  of  any  distant  point 
from  which  they  appear  so  high.  You  seem  to  see  through  the  Pinkham 
Notch,  and  in  that  direction,  from  most  points,  the  higher  peaks  seem 
to  slope  off  and  run  into  the  Carter  range.  Near  Mr.  William  M. 
Thurston's,  the  White  Mountains  still  in  view,  we  can  look  down  on 
Umbagog  lake;  and  then  in  Maine,  not  many  miles  away,  are  moun 
tains  of  considerable  height. 

On  the  Connecticut  there  are  many  places  where  the  scenery  is  en 
chanting.  At  almost  every  turn  in  the  road,  from  West  Stewartstown 
to  North  Stratford,  there  is  something  that  attracts  the  attention, — a 
mountain  of  grand  proportions,  a  hill  with  graceful  outline,  the  trees, 
the  forests,  or  the  river,  as  it  runs  through  grassy  meadows  or  along  a 
wooded  hillside.  There  is  some  remarkable  scenery  in  the  vicinity  of 
Groveton.  Coming  from  the  south  towards  the  village,  Percy  peaks  will 
attract  the  attention  of  the  most  indifferent  observer,  on  account  both  of 
their  symmetrical  form  and  color.  In  the  heliotype,  the  peaks  are  seen 
from  a  point  on  the  Upper  Ammonoosuc  above  Groveton.  In  the  fore 
ground  is  the  river,  and  to  the  right  is  Long  mountain,  near  the  line  of 
Stark  and  Odell.  The  village  itself  is  surrounded  by  mountains.  The 
summits  of  those  that  are  farthest  away  are  scarcely  more  than  ten  miles 
distant,  while  Mt.  Lyon  on  the  south  is  not  more  than  four.  Although 
the  hills  and  mountains  are  so  near,  yet,  on  account  of  the  broad  interval 
of  the  Connecticut,  we  do  not  feel  as  though  the  outlook  had  too  narrow 
limits,  but  rather  that  in  the  whole  view  there  is  a  beautiful  symmetry. 
I  know  of  no  place  where  the  moonlight  adds  such  a  charm  to  the 
scenery ;  and  it  is  especially  grand  to  watch  the  moon  as  it  rises  above 


SCENERY    OF    COOS    COUNTY.  645 

the  Pilot  hills,  breaks  through  the  passing  cloud,  and  throws  its  gentle 
light  across  the  forests. 

If  we  are  not  satisfied  with  the  limit  of  the  valley,  there  are  hills  on 
every  side,  climbing  which  we  have  distant  views.  From  Percy  peaks, 
northward,  we  have  forests  and  wooded  summits ;  south-east,  the  White 
Hills  rise  in  all  their  grandeur;  south,  we  have  the  long  line  of  the 
Pilot  hills ;  and,  a  little  west  of  south,  we  look  down  the  valley  of  the 
Connecticut,  and  in  the  distance  Moosilauke  rises  against  the  sky. 
There  are  few  mountains  one  feels  so  well  repaid  for  the  effort  of  climb 
ing;  and,  besides  the  distant  view,  the  peaks  themselves  are  of  interest 
on  account  of  being  so  similar  in  outline,  and  so  nearly  of  the  same 
height. 

The  summit  of  the  south  peak  is  easily  gained  from  the  south-east,  but 
the  western  slope  of  this,  as  well  as  the  north  peak,  is  so  steep  that  it 
would  require  an  expert  in  climbing  to  be  able  to  reach  the  summit  of 
either  peak  from  that  direction.  There  are  few  mountains  where  the 
variety  of  scenery  is  greater,  for,  besides  the  many  mountain  peaks,  we 
have  the  Upper  Ammonoosuc  and  the  Connecticut  winding  along  the 
valleys,  their  waters  reflecting  the  bright  sunlight,  and  ponds,  too,  sur 
rounded  by  sombre  forests,  nestling  among  the  hills.  Stark  is  a  town 
of  mountains  and  hills,  and  there  are  several  places  where  the  scenery 
is  indeed  picturesque.  Approaching  Stark  station,  either  from  the  east 
or  west,  the  points  of  the  mountains  from  the  opposite  sides  of  the  valley 
project  by  each  other  so  that  there  seems  to  be  an  impassable  barrier 
across  the  valley ;  but  we  know  that  the  stream  must  pass  through  the 
mountains,  and  Stark  station  is  in  the  gap  of  the  mountain  through 
which  it  passes.  On  the  north  is  a  perpendicular  wall  of  rock  forming 
a  vast  amphitheatre,  while  on  the  opposite  side  of  the  valley,  and  a  little 
east,  is  Mill  mountain.  Although  in  every  other  direction  surrounded  by 
high  mountains,  yet,  looking  a  little  west  of  south,  we  can  see  in  the 
distance  some  of  the  high  peaks  of  the  Pilot  range.  At  West  Milan 
the  peaks  of  the  White  Mountains  begin  to  appear,  and,  besides,  there 
is  quite  an  array  of  mountains  westward.  There  are  some  points  where 
the  effect  is  very  fine.  It  is,  however,  in  the  south-east  part  of  Milan, 
near  the  line  of  Berlin,  and  perhaps  a  mile  east  of  the  Androscoggin, 
that  we  have  one  of  the  most  striking  views  of  the  White  Mountains. 


646  PHYSICAL    GEOGRAPHY. 

In  Lancaster  the  view  is  always  grand.  Mt.  Lyon  to  the  north,  and 
thence  eastward  the  broad  sweep  of  the  Pilot  range,  and  the  group  of 
mountains  of  which  Starr  King  is  the  culminating  point,  are  so  situated 
that  every  fine  sunset  gives  to  them  that  deep  coloring  which  is  the 
charm  of  our  mountain  scenery.  Most  of  the  peaks  of  the  White  Moun 
tains  can  be  seen  from  the  village,  but  a  ride  of  two  miles  east  on  the 
road  to  Jefferson,  to  a  point  between  three  hundred  and  four  hundred 
feet  above  the  Connecticut,  brings  them  out  in  bolder  relief,  and  at  the 
same  time  gives  a  charming  view  of  the  village  and  the  Connecticut  val 
ley.  From  Mt.  Pleasant,  which  is  easy  of  access,  the  view  is  still  more 
extended,  and  embraces  the  mountains  southward.  From  Jefferson  hill, 
and  thence  on  the  road  toward  Randolph,  we  get  a  nearer  view  of  the 
mountains ;  and  the  appreciation  of  the  scenery  is  shown  by  the  demand 
for  the  numerous  hotels  in  this  vicinity.  At  the  Mt.  Adams  house,  the 
broad  sweep  of  forests,  reaching  from  Israel's  river  almost  to  the  summits 
of  the  mountains,  gives  us  one  of  the  grandest  of  our  autumn  scenes. 
From  Dalton  mountain  we  have  the  sweep  of  the  whole  horizon:  west 
ward,  the  mountains  in  Vermont ;  the  Connecticut  valley  northward  ;  the 
mountains  of  Stratford,  Mt.  Lyon,  the  Pilot  range,  Starr  King,  all  the 
White  Mountains,  the  chief  of  the  Franconia  Mountains,  and  Moosilauke 
southward. 

ALBANY  SCENERY. — CARROLL  COUNTY. 

Albany,  except  one  broad  interval  in  the  western  part,  is  a  succession 
of  high  ridges  and  mountain  peaks.  Here  is  Chocorua,  with  its  serrated 
mountain  ridge  and  granitic  summit.  Of  all  our  mountains,  there  is 
none  the  summit  of  which  appears  so  colossal  as  this,  when  seen  from 
the  south-east  spur.  As  its  forests  have  been  destroyed,  standing  on 
this  spur,  it  seems  to  be  one  massive  granitic  pile  rising  almost  perpen 
dicular  from  the  ridge.  But  the  mountain  itself  is  grand,  look  at  it  from 
what  direction  we  may, — from  Lake  Winnipiseogee,  Eaton,  or  Conway, 
from  Mt.  Washington,  or  the  mountains  west.  Even  if  we  look  down 
upon  it  as  we  pass  over  this  mountain  region  in  a  balloon, — which  we 
have  had  an  opportunity  of  doing, — on  account  of  its  sharpness  it  seems 
more  prominent  than  many  mountains  of  greater  height.  But  Passacon- 
naway  is  the  highest  mountain  in  Albany,  and,  rising  as  it  does  nearly 


SCENERY    OF    COOS    COUNTY.  647 

3000  feet  above  the  interval  of  Swift  river,  and  having  deep  ravines  on 
the  east  and  west,  from  the  north  it  seems  to  stand  up  massive  and  alone. 
From  the  interval  looking  towards  the  north  and  north-west,  we  have  a 
grand  view  of  the  mountains ;  but,  ascending  any  of  the  small  elevations 
south  of  the  interval,  the  area  of  vision  is  increased  ten-fold.  Towards 
Mt.  Carrigain  the  view  is  almost  unobstructed,  and  there  are  many  gen 
tle  undulations,  with  here  and  there  a  granite  cliff  standing  out  in  bold 
relief,  besides  magnificent  forests  sweeping  away  up  to  the  summits 
of  the  mountains ;  for  none  of  the  mountains  to  the  west  have  been 
denuded  of  trees.  In  full  view,  Mt.  Carrigain  stands  in  all  its  massive 
grandeur,  while  north  and  south  there  are  sharp  peaks  and  mountain 
ridges.  Still  to  the  north,  and  yet  not  so  far  distant  but  that  each  peak 
and  mountain  ridge  stands  in  sharp  outline,  the  White  Mountains  rise  in 
successive  culminations,  until  Mt.  Washington, — monarch  of  the  range, — 
seems  to  touch  the  sky.  While  the  immediate  surroundings  and  the  dis 
tant  views  are  among  the  most  attractive  in  the  whole  mountain  region, 
there  are  two  falls  not  far  from  the  interval,  one  of  which  is  of  exquisite 
beauty.  One  of  the  falls  is  on  Sabba  Day  brook,  just  in  the  edge  of 
Waterville.  The  rock  is  a  common  granite,  in  which  there  is  a  trap 
dyke,  and  it  is  the  disintegration  of  this,  probably,  that  formed  the  chasm 
below  where  the  steep  fall  now  is.  Above,  just  before  we  come  to  the 
falls,  the  stream  turns  to  the  west,  and  the  water  runs  through  a  channel 
worn  in  the  solid  rock,  and  then,  in  one  leap  of  twenty-five  feet,  it 
clears  the  perpendicular  wall  of  rock,  and  falls  into  the  basin  below  al 
most  on  the  opposite  side  of  the  chasm.  Great  is  the  commotion  pro 
duced  by  the  direct  fall  of  so  great  a  body  of  water,  and  out  of  the  basin, 
almost  at  right  angles  with  the  fall,  it  goes  in  whirls  and  eddies.  The 
chasm  extends  perhaps  a  hundred  feet  below  where  the  water  first  strikes. 
Its  width  is  from  ten  to  fifteen  feet,  and  the  height  of  the  wall  is  from 
fifty  to  sixty.  The  water  has  worn  out  the  granite  on  either  side  of  the 
trap,  so  that,  as  the  clear,  limpid  stream  flows  through  the  chasm,  the 
entire  breadth  of  the  dyke  is  seen.  The  fall  of  water,  the  whirls  and 
eddies  of  the  basin,  the  flow  of  the  limpid  stream  over  the  dark  band  of 
trap  set  in  the  bright,  polished  granite,  the  high,  overhanging  wall  of 
rock,  all  combine  to  form  a  picture  of  beauty,  which,  once  fixed  in  the 
mind,  is  a  joy  forever.  The  other  falls  referred  to  are  known  as  Champ- 


648  PHYSICAL    GEOGRAPHY. 

ney  falls.  There  are  two  streams  and  two  falls,  but  they  are  so  near  that 
they  are  known  only  as  Champney  falls.  The  stream  on  which  they  are 
found  is  the  second  stream  that  flows  into  Swift  river  from  the  south 
below  Allen's  saw-mill,  and  they  are  a  mile  and  three  quarters  from  the 
road.  Following  a  logging-road  that  leaves  the  wagon-road  at  the  first 
bridge  below  the  mill,  we  cross  the  stream  on  which  the  falls  are  situated 
just  above  where  they  begin.  A  person  who  goes  without  a  guide,  and 
follows  down  the  stream,  will  be  at  first  disappointed,  for  all  that  is  seen 
is  a  small  stream,  with  a  few  massive  blocks  of  a  granitoid  rock.  It  is 
true  that  even  here  there  are  immense  caverns,  and  here  the  stream  runs 
between  two  blocks,  and  then  over  another,  when  it  falls  on  the  great 
sloping  ledge,  and  goes  bounding  along  until  it  tumbles  over  a  precipitous 
ledge,  and  is  lost  to  view.  We  see  where  the  water  takes  its  last  leap, 
yet  nowhere  does  there  seem  to  be  anything  very  remarkable.  But  a 
person  ought  to  see  all  there  is  to  be  seen  before  judging.  We  climb 
along  the  ledges,  and,  by  following  a  rough  path,  get  to  the  base  of  the 
falls, — yet  there  is  nothing  striking,  nothing  to  see,  certainly,  that  could 
tempt  a  person  to  travel  nearly  two  miles  through  the  woods  alone.  We 
are  about  to  turn  away  sadly  disappointed,  when  the  eye  catches  a  sun 
beam  reflected  from  the  water,  that  seems  to  be  struggling  through  the 
leafy  foliage.  Then,  just  there,  not  a  dozen  rods  away,  but  almost  hidden 
by  the  trees,  we  discover  one  of  the  most  beautiful  falls  in  New  Hamp 
shire.  We  stand  just  at  the  foot  of  the  fall,  on  the  stream  we  followed 
down.  The  sunbeams  fall  aslant  through  the  trees ;  the  eye  follows  the 
high  perpendicular  ledge  that  runs  at  right  angles  to  the  stream,  and 
through  the  leaves  of  the  trees  we  can  see  a  small  stream  where  it  comes 
over  the  ledge,  then  falls  down,  striking  the  rock  that  projects  just  enough 
to  throw  the  water  in  spray,  and  break,  for  an  instant  only,  the  continuity 
of  the  stream.  In  the  entire  fall  there  are  three  of  these  projections, 
where  the  water  is  thrown  in  spray,  and,  after  the  last  continuous  fall,  it 
rests  in  a  quiet  basin,  where  it  flows  out  and  runs  into  the  stream  we  had 
followed  down.  The  entire  fall  may  be  sixty  feet;  and  opposite,  thirty 
feet  distant,  there  is  a  ledge  as  high  as  that  from  which  the  water  falls, 

* 

so  that  probably  where  this  gorge  now  is  there  was  once  an  immense 
trap  dyke,  that  has  been  disintegrated  and  carried  away,  and  now  we 
have  the  beautiful  falls.

Additions  to  the  List  of  Plants.  Since  the  publication  of  the  catalogue  in  Chapter 
XIII,  several  friends  have  added  somewhat  to  the  list.  The  following  are  all  from 
Manchester,  unless  otherwise  specified,  and  they  were  recognized  there  more  than 
twenty  years  since,  before  the  original  growth  had  been  removed  to  make  way  for 
manufactories,  houses,  and  streets.  One  of  the  most  interesting  is  the  Cupressus  thy- 
oides,  as  it  is  a  plant  growing  usually  farther  south.  It  illustrates  the  theory  enunciated 
upon  page  543,  occurring  in  Manchester  in  connection  with  the  Rhododendron.  Italics 
denote  naturalized  plants,  as  before.

As  some  have  thought  the  list  of  lichens,  on  pp.  413  and  414,  was  intended  to  com 
prehend  everything  of  that  class  of  plants,  I  will  take  occasion  to  say  that  it  is  intended 
to  embrace  only  those  which  are  peculiar  to  the  White  Mountains,  but  not  those  which 
grow  there,  and  elsewhere,  also.  The  list  was  compiled  from  Prof.  Tuckerman's  two 
valuable  books,  bearing  the  dates  of  1872  and  1848.  It  is  hoped  that,  by  calling  atten 
tion  to  the  plants  peculiar  to  the  mountains,  botanists  may  be  induced  to  investigate 
further  the  question  of  the  limits  between  the  alpine  and  sub-alpine  districts. 

River  Systems.  Mr.  Upham  desires  to  correct  the  opening  statement  of  Chapter 
XI,  that  one  sixth  part  of  New  Hampshire  is  covered  by  water.  The  estimate  was 
borrowed  without  reflection  from  the  report  of  the  New  Hampshire  Hydrographic  Com 
mission  in  1870.  He  thinks  the  figure  should  be  not  more  than  one  eighteenth,  instead 
of  one  sixth. 

Note  to  page  247.  I  understand  that  the  boundary  between  Carlisle's  and  the  Acad 
emy  grants  has  been  run  out  the  present  season,  in  accordance  with  the  original  line 
of  forty-five  degrees  of  north  latitude. 

Average  Elevation.  The  average  elevation  of  the  land  above  the  ocean  should  have 
been  stated  at  twelve  instead  of  fourteen  hundred  feet,  on  page  296.
