  "Would 
  be 
  carelesness 
  or 
  inexperience 
  that 
  would 
  prevent 
  

   ninety-five 
  per 
  cent, 
  of 
  the 
  eggs 
  from 
  being 
  fertilized." 
  

  

  The 
  great 
  loss 
  of 
  eggs 
  from 
  causes 
  above 
  referred 
  to, 
  makes 
  

   it 
  necessary 
  tliat 
  a 
  very 
  large 
  number 
  of 
  breeding 
  fisli 
  

   should 
  be 
  left 
  to 
  spa\vn, 
  so 
  as 
  to 
  ])rovide 
  for 
  the 
  yearly 
  con- 
  

   sumption. 
  

  

  xA.s 
  the 
  eggs 
  ■which 
  are 
  iiatchcd 
  artificially 
  are 
  taken 
  

   from 
  the 
  fish 
  after 
  they 
  are 
  practically 
  dead 
  and 
  en 
  

   route 
  to 
  market, 
  the 
  young 
  fish 
  derived 
  from 
  this 
  source 
  are 
  

   a 
  clear 
  gain, 
  and 
  must 
  ever 
  be 
  an 
  important 
  addition 
  to 
  

   whatever 
  numbers 
  may 
  be 
  produced 
  by 
  stringent 
  protection. 
  

  

  HATCHING 
  HOUSE. 
  

  

  During 
  the 
  year, 
  the 
  Hatching 
  House 
  has 
  been 
  much 
  im- 
  

   proved 
  and 
  the 
  interior 
  repainted 
  ; 
  the 
  filtering 
  tank 
  in 
  the 
  

   house 
  has 
  been 
  much 
  enlarged, 
  so 
  tliat 
  the 
  Spring 
  v/ater 
  can 
  

   be 
  more 
  slowly 
  and 
  thoroughly 
  cleansed 
  of 
  sediment, 
  ami 
  

   separate 
  filtering 
  tanks 
  have 
  been 
  constructed 
  on 
  an 
  adjacent 
  

   hill, 
  in 
  which 
  the 
  water 
  derived 
  from 
  the 
  city 
  reservoir 
  is 
  

   filtered 
  before 
  being 
  introduced 
  into 
  the 
  building. 
  The 
  ele- 
  

   vated 
  position 
  of 
  these 
  filtering 
  tanks 
  has 
  enabled 
  us 
  to 
  car; 
  v 
  

   the 
  water 
  into 
  the 
  second 
  story 
  ; 
  the 
  tvvo 
  rooms 
  formerly 
  

   occupied 
  by 
  the 
  attendant 
  have 
  been 
  thrown 
  into 
  one, 
  and 
  

   will 
  be 
  used 
  hereafter 
  as 
  a 
  nursery 
  and 
  hatching 
  room, 
  add- 
  

   ing 
  very 
  materially 
  to 
  the 
  capacity 
  of 
  the 
  house. 
  The 
  regu- 
  

   lar 
  routine 
  work 
  connected 
  with 
  the 
  care 
  of 
  spawn 
  of 
  the 
  

   fall 
  and 
  winter 
  spawners, 
  and 
  the 
  distribution 
  of 
  the 
  young 
  

   fish 
  when 
  sufficiently 
  advanced, 
  was 
  conducted 
  during 
  the 
  

   winter 
  of 
  '7C 
  and 
  fall 
  of 
  '77, 
  with 
  the 
  usual 
  success. 
  On 
  

   the 
  1st 
  of 
  May, 
  I 
  found 
  it 
  necessary 
  to 
  transfer 
  the 
  force 
  of 
  

   trained 
  men 
  to 
  the 
  8had-hatching 
  station, 
  and 
  work 
  in 
  this 
  

   department 
  ceased 
  until 
  fill, 
  when 
  active 
  operations 
  com- 
  

   menced 
  with 
  the 
  receipt 
  of 
  200,000 
  eggs 
  of 
  the 
  California 
  

   Salmon. 
  

  

  The 
  details 
  of 
  the 
  distribution 
  of 
  fish 
  from 
  the 
  eggs 
  

   received 
  in 
  the 
  fall 
  of 
  '76, 
  and 
  not 
  included 
  in 
  the 
  last
