  cants. 
  There 
  were 
  shipped 
  to 
  Indiana 
  and 
  Michigan 
  4,000 
  fry 
  during 
  

   April 
  and 
  May, 
  while 
  the 
  remaining 
  fry 
  were 
  kept 
  to 
  replenish 
  the 
  

   ponds. 
  During 
  Juue 
  305 
  yearling 
  and 
  two-year-old 
  wild 
  trout 
  were 
  

   taken 
  from 
  the 
  streams 
  of 
  Northern 
  Michigan 
  and 
  brought 
  to 
  the 
  North 
  

   ville 
  Station. 
  During 
  March, 
  April, 
  and 
  May 
  550 
  yearling 
  brook 
  trout 
  

   were 
  distributed 
  from 
  the 
  station 
  to 
  six 
  private 
  persons 
  in 
  Michigan, 
  

   Indiana, 
  and 
  Ohio. 
  

  

  The 
  Gold 
  Spring 
  Harbor 
  Station. 
  — 
  During 
  January 
  7,000 
  eggs 
  were 
  

   received 
  from 
  the 
  Northville 
  Station, 
  from 
  which 
  about 
  5,800 
  healthy 
  

   fry 
  were 
  obtained. 
  These 
  fry, 
  with 
  10,500 
  others 
  from 
  eggs 
  taken 
  at 
  

   the 
  hatchery, 
  were 
  planted 
  in 
  streams 
  of 
  Long 
  Island.

  Lake 
  Trout

  The 
  demand 
  for 
  some 
  species 
  of 
  fish 
  other 
  than 
  carp 
  for 
  pond 
  culture 
  

   is 
  growing 
  so 
  rapidly 
  that 
  it 
  bids 
  fair 
  to 
  equal 
  that 
  which 
  has 
  hereto- 
  

   fore 
  existed 
  for 
  carp. 
  In 
  ordinary 
  ponds 
  fed 
  by 
  surface 
  water, 
  the 
  sum- 
  

   mer 
  temperature 
  of 
  which 
  rises 
  above 
  00°, 
  some 
  species 
  of 
  Gentrarchidce 
  

   would 
  probably 
  be 
  best. 
  There 
  are, 
  however, 
  all 
  over 
  the 
  Northern 
  

   States 
  facilities 
  for 
  the 
  construction 
  of 
  ponds 
  by 
  damming 
  back 
  spring 
  

   branches 
  in 
  which 
  the 
  summer 
  temperature 
  of 
  water 
  is 
  certainly 
  too 
  

   low 
  for 
  the 
  proper 
  cultivation 
  of 
  carp. 
  To 
  supply 
  the 
  desideratum 
  in 
  

   reference 
  to 
  this 
  it 
  will 
  be 
  necessary 
  to 
  provide 
  some 
  species 
  of 
  Sal- 
  

   monidce 
  adapted 
  to 
  pond 
  culture. 
  'The 
  California 
  trout 
  and 
  the 
  lake 
  

   trout 
  — 
  especially 
  the 
  latter 
  — 
  would 
  seem 
  to 
  be 
  best 
  adapted 
  to 
  the 
  pur- 
  

   pose. 
  The 
  experiment 
  should 
  be 
  made 
  on 
  such 
  a 
  scale 
  and 
  under 
  such 
  

   variety 
  of 
  conditions 
  as 
  will 
  thoroughly 
  test 
  its 
  feasibility. 
  Believing 
  

   that 
  the 
  lack 
  of 
  success 
  heretofore 
  experienced 
  in 
  planting 
  Salmonidce 
  

   has 
  been 
  due 
  to 
  their 
  helpless 
  condition 
  when 
  planted, 
  it 
  seems 
  advis 
  

   able 
  to 
  hold 
  them 
  until 
  they 
  have 
  attained 
  a 
  length 
  of 
  5 
  or 
  6 
  inches, 
  

   when, 
  from 
  their 
  size 
  and 
  vigor, 
  they 
  are 
  almost 
  safe 
  from 
  the 
  attack 
  of 
  

   predaceous 
  fishes 
  that 
  may 
  be 
  in 
  the 
  water. 
  A 
  trout 
  of 
  the 
  size 
  and 
  

   age 
  indicated 
  would 
  seem 
  to 
  have 
  as 
  fair 
  a 
  probability 
  of 
  life 
  as 
  a 
  full- 
  

   fledged 
  birdling. 
  One 
  hundred 
  such 
  placed 
  in 
  a 
  stream 
  or 
  pond, 
  under 
  

   natural 
  or 
  artificial 
  conditions 
  which 
  are 
  favorable, 
  would 
  give 
  a 
  better 
  

   promise 
  of 
  success 
  than 
  the 
  planting 
  of 
  10,000 
  fry 
  under 
  the 
  same 
  con- 
  

   ditions 
  prior 
  to 
  the 
  absorption 
  of 
  their 
  sacs. 
  

  

  The 
  Bucltsport 
  Station. 
  — 
  For 
  the 
  purpose 
  of 
  furthering 
  the 
  experi- 
  

   ments 
  indicated, 
  Mr. 
  Clark 
  was 
  directed 
  on 
  November 
  14, 
  1885, 
  to 
  for- 
  

   ward 
  to 
  Bucksport, 
  from 
  the 
  eggs 
  then 
  ready 
  for 
  distribution, 
  50,000 
  

   lake 
  trout 
  eggs 
  and 
  an 
  additional 
  50,000 
  as 
  soon 
  as 
  they 
  were 
  ready. 
  

   Mr. 
  Atkins 
  was 
  instructed 
  to 
  retain 
  as 
  large 
  a 
  number 
  as 
  he 
  could 
  safely 
  

   care 
  for, 
  pi 
  anting 
  the 
  balance 
  in 
  suitable 
  waters 
  in 
  the 
  vicinity. 
  It 
  was 
  

   thought 
  that 
  the 
  fry 
  could 
  be 
  retained 
  in 
  the 
  hatching-troughs 
  until 
  

   the 
  following 
  May 
  or 
  June, 
  which 
  would 
  meantime 
  give 
  an 
  opportunity 
  

   to 
  make 
  provision 
  for 
  them 
  in 
  the 
  ponds. 
  The 
  100,000 
  eggs 
  safely 
  

   reached 
  Bucksport 
  and 
  were 
  hatched 
  without 
  material 
  loss, 
  and 
  in 
  the 
  

   middle 
  of 
  May, 
  1886, 
  were 
  still 
  in 
  good 
  condition.
