  By 
  supplanting 
  them 
  with 
  brook 
  trout 
  and 
  German 
  trout, 
  or 
  by 
  concen- 
  

   trating 
  the 
  divided 
  forces 
  on 
  one 
  line, 
  the 
  aggregate 
  results 
  would 
  

   be 
  greatly 
  increased. 
  

  

  A 
  few 
  of 
  the 
  German 
  trout, 
  from 
  stock 
  raised 
  from 
  eggs 
  received 
  at 
  

   Northville 
  in 
  the 
  spring 
  of 
  1883, 
  spawned 
  last 
  December. 
  In 
  all, 
  8,000 
  

   eggs 
  of 
  prime 
  quality 
  were 
  taken. 
  In 
  addition, 
  two 
  consignments 
  of 
  

   these 
  eggs 
  were 
  received 
  from 
  Fred 
  Mather. 
  The 
  first 
  lot, 
  10,000 
  in 
  

   number, 
  arrived 
  on 
  March 
  25, 
  in 
  good 
  condition; 
  the 
  second 
  lot, 
  13,000 
  

   in 
  number, 
  on 
  April 
  23, 
  in 
  very 
  poor 
  condition, 
  about 
  one-half 
  having 
  

   hatched 
  en 
  route. 
  The 
  stock 
  fish 
  of 
  this 
  species 
  in 
  the 
  Northville 
  ponds 
  

   show 
  a 
  better 
  and 
  more 
  uniform 
  growth 
  than 
  our 
  brook 
  trout, 
  and 
  

   promise 
  exceedingly 
  well. 
  

  

  A 
  case 
  of 
  29,000 
  eggs 
  of 
  landlocked 
  salmon 
  was 
  transferred 
  from 
  

   Grand 
  Lake 
  Stream, 
  Maine, 
  arriving 
  on 
  March 
  19 
  in 
  fine 
  condition. 
  The 
  

   hatching 
  percentage 
  was 
  very 
  good, 
  but 
  there 
  was 
  considerable 
  loss 
  on 
  

   fry. 
  Total 
  number 
  of 
  fry 
  distributed, 
  22,000. 
  

  

  The 
  distribution 
  of 
  stock 
  fish 
  from 
  the 
  ponds 
  of 
  the 
  Northville 
  Sta- 
  

   tion 
  was 
  successfully 
  carried 
  on 
  during 
  the 
  past 
  spring, 
  chiefly 
  by 
  car 
  

   No. 
  2, 
  the 
  remainder 
  by 
  special 
  messengers. 
  The 
  fish 
  thus 
  disposed 
  of 
  

   were 
  yearling 
  and 
  two-year-old 
  brook 
  and 
  rainbow 
  trout. 
  The 
  number 
  

   disbursed 
  to 
  each 
  applicant 
  or 
  locality 
  was 
  small 
  as 
  compared 
  with 
  the 
  

   usual 
  assignments 
  of 
  fry, 
  but 
  the 
  relative 
  importance 
  of 
  the 
  distribu- 
  

   tion 
  should 
  not 
  on 
  this 
  account 
  be 
  underestimated. 
  The 
  measure 
  of 
  

   results, 
  I 
  am 
  thoroughly 
  satisfied, 
  will 
  be 
  a 
  hundred-fold 
  greater. 
  Time 
  

   will 
  prove 
  — 
  if, 
  indeed, 
  it 
  has 
  not 
  already 
  done 
  so 
  — 
  the 
  wisdom 
  of 
  the 
  

   plan 
  of 
  using 
  fish 
  not 
  less 
  than 
  a 
  year 
  old 
  for 
  stocking 
  new 
  waters. 
  

  

  During 
  the 
  fall 
  and 
  winter 
  4,000 
  carp 
  from 
  the 
  national 
  ponds 
  at 
  

   Washington 
  were 
  forwarded, 
  on 
  orders, 
  to 
  applicants 
  ; 
  also 
  85 
  gold- 
  

   fish. 
  

  

  A 
  few 
  thousand 
  eggs 
  of 
  German 
  whitefish, 
  and 
  about 
  the 
  same 
  num- 
  

   ber 
  of 
  smelt, 
  were 
  forwarded 
  to 
  Northville 
  by 
  Fred 
  Mather 
  last 
  spring, 
  

   but 
  they 
  were 
  in 
  very 
  poor 
  condition 
  and 
  few 
  hatched. 
  The 
  final 
  re- 
  

   sults 
  were 
  purely 
  negative, 
  as 
  the 
  young 
  fish 
  soon 
  died. 
  

  

  Two 
  new 
  ponds, 
  each 
  10 
  by 
  40 
  feet, 
  were 
  added 
  to 
  the 
  plant 
  of 
  the 
  

   Northville 
  Station 
  during 
  the 
  first 
  two 
  months 
  of 
  the 
  fiscal 
  year, 
  and 
  two 
  

   others 
  were 
  subdivided 
  into 
  sections, 
  thus 
  affording 
  more 
  perfect 
  iso- 
  

   lation 
  of 
  the 
  various 
  sizes 
  and 
  varieties 
  in 
  stock. 
  

  

  WHITEFISH. 
  

  

  In 
  submitting 
  this 
  report 
  of 
  the 
  operations 
  in 
  the 
  whitefish 
  depart- 
  

   ment 
  I 
  am 
  gratified 
  to 
  announce 
  that 
  the 
  past 
  season 
  has 
  been 
  abun- 
  

   dantly 
  fruitful 
  of 
  good 
  results 
  in 
  the 
  three 
  important 
  divisions 
  into 
  

   which 
  successful 
  propagation 
  naturally 
  divides 
  itself, 
  namely, 
  first, 
  col- 
  

   lection 
  of 
  spawn 
  ; 
  second, 
  hatching 
  of 
  same 
  ; 
  third, 
  distribution 
  of 
  fry. 
  

  

  During 
  the 
  months 
  of 
  November 
  and 
  December 
  upwards 
  of 
  100,000,- 
  

   000 
  whitefish 
  eggs 
  were 
  received 
  at 
  Northville 
  Hatchery 
  and 
  68,000,000
