  points 
  in 
  future, 
  but 
  it 
  will 
  be 
  necessary 
  to 
  construct 
  temporary 
  hatch- 
  

   eries, 
  so 
  that 
  eggs 
  may 
  be 
  eyed 
  before 
  beiug 
  transferred 
  to 
  the 
  station. 
  

  

  Baikd 
  Station, 
  C'ai-ifornia 
  (Livingston 
  Stone, 
  Superintendent). 
  

  

  Early 
  in 
  July 
  the 
  rack 
  to 
  prevent 
  the 
  ascent 
  of 
  the 
  salmon 
  was 
  com- 
  

   pleted 
  and 
  a 
  wagon 
  and 
  foot 
  bridge 
  was 
  built 
  across 
  the 
  river. 
  A 
  new 
  

   current-wheel, 
  spawning-house, 
  salmon 
  corrals, 
  etc., 
  were 
  constructed 
  

   by 
  the 
  station 
  force. 
  

  

  The 
  first 
  ripe 
  salmon 
  were 
  captured 
  on 
  August 
  21, 
  and 
  eggs 
  were 
  

   taken 
  daily 
  from 
  that 
  time 
  to 
  Septemb/cr 
  16, 
  the 
  total 
  collection 
  aggre- 
  

   gating 
  5,000,000. 
  These 
  were 
  held 
  until 
  the 
  eye-spots 
  appeared, 
  when 
  

   they 
  were 
  shipx)ed 
  to 
  the 
  State 
  hatchery 
  at 
  Sisson, 
  Cal. 
  The 
  last 
  of 
  

   them 
  were 
  disposed 
  of 
  by 
  October 
  20, 
  and 
  as 
  it 
  had 
  been 
  decided 
  not 
  

   to 
  make 
  collections 
  from 
  the 
  late 
  run 
  of 
  salmon 
  arrangements 
  were 
  

   made 
  for 
  the 
  transfer 
  of 
  a 
  large 
  part 
  of 
  the 
  equipment 
  and 
  the 
  force 
  to 
  

   Battle 
  Creek 
  Station. 
  During 
  December 
  over 
  2,000,000 
  salmon 
  eggs 
  

   were 
  forwarded 
  to 
  Baird 
  from 
  that 
  station, 
  to 
  be 
  hatched 
  and 
  liberated 
  

   in 
  McCloud 
  River. 
  To 
  prevent 
  the 
  crowding 
  of 
  the 
  troughs, 
  1,000,000 
  

   of 
  the 
  fry 
  were 
  liberated 
  in 
  January; 
  the 
  remainder 
  were 
  divided 
  

   into 
  four 
  lots 
  and 
  experiments 
  were 
  tried 
  for 
  the 
  purpose 
  of 
  determining 
  

   what 
  preparation 
  of 
  food 
  would 
  produce 
  the 
  best 
  results. 
  The 
  first 
  lot 
  

   was 
  fed 
  on 
  liver 
  exclusively, 
  the 
  second 
  on 
  a 
  mixture 
  composed 
  of 
  three 
  

   parts 
  liver 
  to 
  one 
  of 
  inush, 
  the 
  third 
  on 
  equal 
  parts 
  of 
  mush 
  and 
  liver, 
  

   and 
  the 
  fourth 
  on 
  three 
  parts 
  mush 
  to 
  one 
  of 
  liver. 
  The 
  fish 
  fed 
  on 
  

   liver 
  exclusively 
  were 
  found 
  to 
  exhibit 
  a 
  marked 
  superiority 
  in 
  size 
  and 
  

   strength 
  over 
  those 
  fed 
  on 
  the 
  mixtures, 
  but 
  there 
  was 
  very 
  little 
  

   difference 
  in 
  the 
  condition 
  of 
  the 
  three 
  lots 
  fed 
  on 
  liver 
  and 
  mush 
  in 
  

   varying 
  proportions. 
  

  

  Early 
  in 
  June 
  the 
  work 
  of 
  commencing 
  a 
  new 
  rack 
  and 
  bridge 
  for 
  

   the 
  coming 
  season 
  was 
  undertaken, 
  and 
  the 
  indications 
  point 
  to 
  a 
  very 
  

   large 
  run 
  of 
  salmon. 
  

  

  The 
  following 
  tables 
  show 
  the 
  daily 
  take 
  of 
  salmon, 
  the 
  daily 
  collec-

  and

  maximum, 
  minimum,
