  iiiiul 
  and 
  sodiineut, 
  as 
  in 
  some 
  instances 
  enongii 
  would 
  collect 
  in 
  one 
  

   night 
  to 
  entirely 
  bury 
  eggs 
  and 
  trays. 
  It 
  appears 
  from 
  experience 
  

   gained 
  during 
  the 
  past 
  season 
  that, 
  although 
  eggs 
  may 
  be 
  successfully 
  

   hatched 
  in 
  pure 
  water 
  of 
  a 
  temperature 
  as 
  low 
  as 
  that 
  recorded 
  at 
  the 
  

   station, 
  in 
  all 
  instances 
  the 
  eggs 
  should 
  be 
  eyed 
  before 
  subjecting 
  them 
  

   to 
  it. 
  The 
  loss 
  on 
  the 
  first 
  lots 
  taken 
  was 
  mucli 
  less 
  than 
  on 
  those 
  

   which 
  were 
  not 
  eyed 
  at 
  the 
  time 
  the 
  temperature 
  became 
  so 
  low. 
  In 
  

   addition 
  to 
  collections 
  made 
  in 
  the 
  vicinity 
  of 
  the 
  station, 
  consignments 
  

   of 
  Atlantic 
  salmon 
  and 
  rainbow 
  and 
  lake 
  trout 
  were 
  received 
  from 
  other 
  

   stations. 
  

  

  Atlantic 
  satmoii. 
  — 
  In 
  January 
  25,000 
  of 
  these 
  eggs 
  were 
  shipped 
  from 
  

   Craig 
  IJrook 
  Station. 
  They 
  hatched 
  about 
  three 
  months 
  afterwards, 
  

   the 
  loss 
  on 
  them 
  being 
  2,405. 
  Of 
  the 
  fry, 
  19,000 
  were 
  planted 
  in 
  Merri- 
  

   mac 
  Kiver 
  at 
  Concord 
  and 
  the 
  balance 
  were 
  retained 
  for 
  rearing. 
  

  

  Rainbow 
  trout. 
  — 
  Three 
  consignments 
  of 
  rainbow-trout 
  eggs, 
  aggre- 
  

   gating 
  75,000, 
  were 
  received 
  from 
  Wytheville 
  Station. 
  Though 
  tlie 
  first 
  

   package 
  was 
  overheated, 
  the 
  eggs 
  ai^peared 
  to 
  be 
  in 
  good 
  condition; 
  

   the 
  second 
  box 
  had 
  apparently 
  been 
  overturned, 
  but 
  the 
  third 
  showed 
  

   no 
  signs 
  of 
  rough 
  handling. 
  A 
  very 
  few 
  days 
  after 
  the 
  eggs 
  were 
  

   received 
  white 
  spots 
  aj)peared 
  on 
  nearly 
  all 
  of 
  them. 
  The 
  water 
  at 
  

   Wytheville 
  was 
  about 
  22^ 
  warmer 
  than 
  that 
  at 
  St. 
  Johnsbury, 
  and 
  as 
  the 
  

   same 
  trouble 
  has 
  been 
  experienced 
  at 
  the 
  Duluth 
  Station 
  under 
  similar 
  

   conditions 
  of 
  temperature 
  it 
  is 
  inferred 
  that 
  the 
  spots 
  originate 
  from 
  

   the 
  great 
  difference 
  in 
  the 
  temperature 
  of 
  the 
  water. 
  Of 
  the 
  75,000 
  

   eggs 
  received, 
  there 
  was 
  a 
  loss 
  of 
  only 
  3,341 
  after 
  they 
  were 
  laid 
  down 
  

   in 
  the 
  troughs, 
  but 
  the 
  fry 
  were 
  weak 
  and 
  only 
  26,700 
  were 
  saved. 
  These 
  

   were 
  planted 
  at 
  the 
  following 
  points: 
  10,000 
  to 
  East 
  Creek, 
  Itutland 
  

   County, 
  Vt. 
  ; 
  8,000 
  to 
  Isinglass 
  Eiver, 
  Strafford 
  County, 
  l!^. 
  H. 
  ; 
  8,000 
  to 
  

   (Ireat 
  Brook, 
  Eockingham 
  County, 
  N. 
  H. 
  ,• 
  700 
  retained 
  at 
  the 
  hatchery. 
  

  

  Lal^e 
  trout. 
  — 
  From 
  eggs 
  received 
  from 
  Xorthville, 
  93,698 
  fry 
  were 
  

   produced, 
  most 
  of 
  them 
  hatching 
  during 
  a 
  period 
  of 
  freshets, 
  when 
  the 
  

   water 
  suddenly 
  became 
  warmer 
  and 
  was 
  so 
  muddy 
  that 
  the 
  fry 
  could 
  

   not 
  be 
  seen 
  in 
  it 
  for 
  several 
  days. 
  The 
  loss 
  amounted 
  to 
  39,524, 
  and 
  the 
  

   remaining 
  54,174 
  were 
  distributed 
  to 
  applicants 
  in 
  Massachusetts 
  and 
  

   Vermont. 
  

  

  During 
  the 
  winter 
  the 
  superintendent 
  made 
  a 
  careful 
  examination 
  of 
  

   tlie 
  springs 
  in 
  the 
  vicinity 
  of 
  the 
  station 
  with 
  the 
  view 
  to 
  increasing 
  

   the 
  water 
  supply. 
  Options 
  were 
  secured 
  on 
  a 
  number 
  of 
  them, 
  but 
  the 
  

   amount 
  of 
  water 
  they 
  were 
  capable 
  of 
  furnishing 
  was 
  too 
  small 
  as 
  

   compared 
  with 
  the 
  expense 
  that 
  would 
  have 
  been 
  incurred 
  in 
  their 
  

   purchase 
  and 
  the 
  piping 
  of 
  the 
  water 
  to 
  the 
  hatchery. 
  The 
  total 
  sup- 
  

   ply 
  from 
  all 
  the 
  si)rings 
  in 
  the 
  vicinity, 
  12 
  in 
  number, 
  would 
  not 
  have 
  

   amounted 
  to 
  more 
  than 
  125 
  gallons 
  per 
  minute, 
  and 
  even 
  this 
  amount 
  

   was 
  uncertain, 
  as 
  the 
  investigation 
  was 
  made 
  when 
  the 
  ground 
  was 
  

   covered 
  several 
  feet 
  deep 
  with 
  snow. 
  An 
  appropriation 
  was 
  secured 
  

   for 
  the 
  development 
  of 
  the 
  spring 
  water 
  on 
  the 
  station 
  proi»erty, 
  and
