  then 
  our 
  efforts 
  met 
  with 
  interference 
  which 
  made 
  their 
  successful 
  prose- 
  

   cution 
  impossible. 
  Before 
  they 
  were 
  abandoned, 
  however, 
  the 
  stomachs 
  

   of 
  some 
  27 
  brook 
  trout 
  were 
  obtained, 
  and 
  their 
  contents 
  (consisting 
  

   almost 
  wholly 
  of 
  insects), 
  cleaned 
  and 
  preserved, 
  are 
  now 
  part 
  of 
  the 
  

   state 
  museum 
  collection. 
  The 
  records 
  of 
  the 
  numerous 
  insects 
  collected 
  

   during 
  these 
  few 
  days 
  about 
  the 
  shores 
  of 
  Bone 
  pond 
  will 
  be 
  found 
  under 
  

   their 
  respective 
  species 
  in 
  part 
  3 
  of 
  this 
  report, 
  and 
  a 
  brief 
  account 
  

   of 
  the 
  vegetation, 
  above 
  in 
  the 
  introduction. 
  A 
  random 
  report 
  on 
  the 
  

   fish 
  food 
  there 
  collected 
  may 
  yet 
  be 
  made 
  from 
  the 
  material 
  I 
  prepared, 
  

   but 
  it 
  will 
  of 
  necessity 
  lack 
  the 
  features 
  which 
  I 
  counted 
  most 
  essential, 
  

   unless 
  farther 
  study 
  be 
  made 
  at 
  the 
  pond 
  itself. 
  

  

  Bullfrogs 
  were 
  common 
  in 
  Little 
  Clear 
  creek, 
  and 
  I 
  collected 
  the 
  

   stomach 
  contents 
  of 
  25 
  of 
  them. 
  Lack 
  of 
  tiaie 
  is 
  the 
  only 
  reason 
  why 
  

   they 
  have 
  not 
  been 
  studied, 
  and 
  are 
  not 
  reported 
  on 
  at 
  the 
  present 
  time. 
  

  

  Life 
  histories 
  of 
  insects. 
  One 
  of 
  the 
  first 
  decisions 
  made 
  with 
  

   respect 
  to 
  station 
  work 
  was 
  that 
  no 
  greater 
  service 
  could 
  be 
  done 
  for 
  

   aquatic 
  entomology, 
  pure 
  or 
  applied, 
  than 
  adding 
  as 
  opportunity 
  offered 
  

   to 
  present 
  knowledge 
  of 
  insect 
  life 
  histories. 
  So 
  long 
  as 
  the 
  species 
  

   can 
  not 
  be 
  recognized 
  in 
  their 
  immature 
  stages, 
  Httle 
  progress 
  is 
  possible 
  

   in 
  food 
  studies, 
  or 
  in 
  quantitative 
  studies 
  of 
  any 
  sort. 
  To 
  this 
  absolutely 
  

   necessary 
  preliminary 
  work, 
  therefore, 
  much 
  the 
  greater 
  part 
  of 
  our 
  time 
  

   ivas 
  given. 
  

  

  We 
  were 
  able 
  to 
  work 
  out 
  more 
  or 
  less 
  completely 
  the 
  life 
  histories 
  of 
  

   about 
  a 
  hundred 
  species 
  of 
  aquatic 
  insects, 
  immature 
  stages 
  of 
  most 
  of 
  

   which 
  are 
  described 
  in 
  part 
  3 
  of 
  this 
  report. 
  Those 
  who 
  have 
  done 
  life 
  

   history 
  v/ork 
  will 
  not 
  need 
  to 
  be 
  told 
  that 
  this 
  work 
  occupied 
  rather 
  fully 
  

   the 
  available 
  time 
  of 
  our 
  short 
  session. 
  

  

  In 
  order 
  to 
  make 
  part 
  3 
  serviceable 
  to 
  teachers 
  and 
  students, 
  I 
  have 
  

   filled 
  it 
  with 
  keys 
  and 
  tables 
  for 
  determining 
  the 
  orders, 
  families, 
  genera 
  

   and 
  species 
  of 
  immature 
  stages 
  of 
  aquatic 
  insects, 
  and 
  have 
  illustrated 
  

   these 
  with 
  special 
  figures 
  explaining 
  the 
  terms 
  used. 
  The 
  several 
  

   orders 
  will 
  be 
  found 
  to 
  have 
  received 
  very 
  unequal 
  treatment, 
  because 
  

   we 
  wished 
  to 
  add 
  chiefly 
  to 
  the 
  knowledge 
  of 
  the 
  things 
  least 
  known. 
  

   For 
  this 
  reason 
  the 
  larvae 
  of 
  Diptera 
  and 
  Coleoptera 
  received 
  much 
  less 
  

   than 
  a 
  fair 
  share 
  of 
  attention 
  ; 
  for 
  they 
  are 
  already 
  much 
  better 
  known 
  

   than 
  are 
  the 
  larvae 
  of 
  the 
  other 
  orders 
  treated. 
  

  

  More 
  dragon 
  flies 
  than 
  anything 
  else 
  were 
  reared. 
  There 
  are 
  two 
  

   reasons 
  for 
  this 
  : 
  Saranac 
  Inn 
  is 
  a 
  splendid 
  locality 
  for 
  dragon 
  flies, 
  and 
  

   I 
  have 
  been 
  rearing 
  dragon 
  flies 
  for 
  a 
  number 
  of 
  years 
  and 
  have 
  learned 
  

   how 
  to 
  do 
  it. 
  With 
  slight 
  additions 
  from 
  my 
  former 
  breedings, 
  I 
  have
