  The 
  eggs 
  turned 
  out 
  very 
  poorly, 
  only 
  35,000 
  being 
  saved, 
  of 
  which 
  

   3,000 
  were 
  shipped 
  to 
  B. 
  F. 
  Ferris, 
  Castalia, 
  Ohio, 
  and 
  2,000 
  to 
  S. 
  B. 
  

   Smith, 
  Zanesville, 
  Ohio. 
  The 
  remaining 
  30,000 
  hatched 
  ; 
  but 
  a 
  large 
  

   percentage 
  of 
  the 
  young 
  fish 
  died 
  within 
  sis 
  weeks, 
  despite 
  the 
  greatest 
  

   care 
  and 
  attention. 
  Not 
  more 
  than 
  5,000 
  survived 
  the 
  critical 
  period 
  of 
  

   trout 
  raising, 
  namely, 
  the 
  first 
  three 
  weeks 
  after 
  the 
  absorption 
  of 
  the 
  

   food 
  sac. 
  The 
  continued 
  meager 
  returns 
  from 
  this 
  variety 
  of 
  trout 
  

   scarcely 
  justifies 
  a 
  continuance 
  of 
  this 
  branch 
  of 
  the 
  service 
  at 
  the 
  

   Northville 
  Station. 
  It 
  would 
  seem 
  that 
  the 
  species 
  will 
  not 
  acclimatize 
  

   to 
  the 
  waters 
  of 
  this 
  station, 
  notwithstanding 
  the 
  special 
  effort 
  that 
  has 
  

   been 
  made 
  for 
  a 
  number 
  of 
  years 
  to 
  bring 
  about 
  this 
  result. 
  The 
  waters 
  

   are 
  well 
  adapted 
  to 
  brook 
  trout, 
  and 
  it 
  would 
  seem 
  to 
  be 
  a 
  wise 
  policy 
  

   to 
  displace 
  the 
  rainbow 
  trout 
  by 
  the 
  brook 
  trout 
  as 
  soon 
  as 
  possible.

  TROUT. 
  

  

  The 
  season's 
  work 
  in 
  this 
  species 
  has 
  been 
  unprecedented 
  in 
  the 
  history 
  

   'of 
  the 
  hatchery, 
  having 
  received 
  nearly 
  one 
  and 
  one-half 
  million 
  of 
  eggs 
  

   from 
  the 
  spawning 
  grounds 
  of 
  Lake 
  Huron, 
  in 
  the 
  vicinity 
  of 
  Alpena
