  experiments, 
  in 
  making 
  quantitative 
  studies 
  of 
  the 
  life 
  of 
  certain 
  situations, 
  

   in 
  gathering 
  the 
  materials 
  for 
  the 
  study 
  of 
  the 
  natural 
  and 
  habitual 
  food 
  

   of 
  trout, 
  bullfrogs, 
  and 
  some 
  of 
  the 
  larger 
  species 
  of 
  dragon 
  flies, 
  in 
  run- 
  

   ning 
  trap 
  lanterns 
  and 
  sending 
  their 
  nightly 
  catch 
  to 
  the 
  state 
  museum, 
  etc. 
  

   Besides 
  three 
  official 
  visits 
  made 
  by 
  Dr 
  Felt 
  during 
  the 
  course 
  of 
  our 
  

   session, 
  our 
  station 
  was 
  visited 
  for 
  a 
  week 
  or 
  more 
  at 
  a 
  time 
  by 
  three 
  

   scientific 
  friends, 
  who, 
  while 
  there, 
  participated 
  in 
  our 
  operations, 
  and, 
  

   while 
  collecting 
  for 
  themselves, 
  gathered 
  also 
  valuable 
  materials 
  and 
  

   information 
  for 
  us. 
  These 
  were 
  Louis 
  W. 
  Swett 
  of 
  Maiden 
  Mass., 
  H. 
  N. 
  

   Rowland 
  of 
  Austin

  and 
  Dr 
  O. 
  S. 
  Westcott 
  of 
  Chicago. 
  It 
  is 
  a 
  

   pleasure 
  to 
  acknowledge 
  the 
  assistance 
  gratuitously 
  rendered 
  by 
  these 
  

   gentlemen. 
  

  

  Biologic 
  features 
  of 
  the 
  locality 
  

  

  As 
  is 
  well 
  known, 
  the 
  Adirondack 
  region 
  of 
  northeastern 
  New 
  York 
  

   is 
  an 
  extensive 
  area 
  of 
  forest, 
  having 
  an 
  average 
  elevation 
  of 
  about 
  1800 
  

   feet. 
  Its 
  eastern 
  half 
  is 
  covered 
  with 
  a 
  succession 
  of 
  low 
  mountain 
  

   ranges, 
  whose 
  general 
  n 
  n 
  e-s 
  s 
  w 
  trend 
  is 
  indicated 
  on 
  the 
  accompanying 
  

   map 
  (map 
  i) 
  by 
  the 
  trend 
  of 
  the 
  streams 
  which 
  occupy 
  the 
  narrow 
  

   valleys 
  between 
  them. 
  The 
  western 
  half 
  is 
  a 
  region 
  of 
  lakes 
  and 
  swamps 
  

   and 
  bogs, 
  with 
  scattered 
  mountains 
  and 
  hills 
  and 
  ridges. 
  

  

  Map 
  I 
  shows 
  the 
  principal 
  streams 
  that 
  participate 
  in 
  the 
  drainage 
  of 
  

   the 
  Adirondack 
  region, 
  the 
  principal 
  lakes, 
  and 
  some 
  of 
  the 
  mountains. 
  

   It 
  will 
  be 
  observed 
  that 
  the 
  lake 
  region 
  of 
  the 
  Adirondacks 
  is 
  drained 
  

   principally 
  through 
  Racket 
  river 
  into 
  the 
  St 
  Lawrence. 
  

  

  Saranac 
  river 
  is 
  the 
  only 
  one 
  on 
  the 
  Champlain 
  side 
  that 
  drains 
  any 
  

   considerable 
  part 
  of 
  the 
  lake 
  country. 
  Our 
  station 
  at 
  Saranac 
  Inn 
  was 
  

   at 
  the 
  head 
  of 
  the 
  Saranac 
  drainage 
  system. 
  Map

  shows 
  the 
  

   immediate 
  field 
  of 
  our 
  operations. 
  As 
  stated 
  above, 
  the 
  hatchery 
  was 
  

   our 
  working 
  headquarters. 
  We 
  did 
  more 
  collecting 
  from 
  Little 
  Clear 
  

   creek 
  right 
  on 
  the 
  hatchery 
  grounds 
  than 
  from 
  any 
  other 
  equal 
  water 
  

   area, 
  and 
  obtained 
  more 
  material 
  of 
  value 
  there 
  than 
  in 
  all 
  other 
  places 
  

   combined. 
  More 
  or 
  less 
  regular 
  collecting 
  was 
  done, 
  however, 
  from 
  the 
  

   three 
  propagating 
  ponds. 
  Little 
  Clear, 
  Little 
  Green 
  and 
  Bone, 
  and 
  from 
  

   Little 
  Bog 
  pond, 
  southwest 
  of 
  the 
  railroad 
  station. 
  Two 
  collecting 
  trips 
  

   were 
  made 
  to 
  each 
  of 
  the 
  following 
  places 
  : 
  Colby 
  pond, 
  at 
  the 
  western 
  

   outskirts 
  of 
  the 
  village 
  of 
  Saranac 
  Lake; 
  Stony 
  brook, 
  just 
  north 
  of 
  

   Axton; 
  and 
  St 
  Regis 
  pond, 
  at 
  the 
  end 
  of 
  the 
  carry 
  from 
  Little 
  Clear. 
  

   The 
  mornings 
  and 
  evenings 
  of 
  the 
  first 
  week 
  of 
  the 
  session 
  were 
  spent 
  

   gathering 
  material 
  about 
  the 
  south 
  shore 
  of 
  Lake 
  Clear, 
  or 
  Big 
  Clear 
  at 
  

   Otisville.
