  troughs 
  were 
  provided, 
  the 
  trap 
  was 
  built 
  below 
  the 
  rack 
  for 
  the 
  cap- 
  

   ture 
  of 
  the 
  fish, 
  and 
  a 
  Hume 
  was 
  laid 
  from 
  a 
  small 
  brook 
  near 
  by, 
  from 
  

   which 
  the 
  water 
  supply 
  was 
  obtained 
  by 
  gravity. 
  Salmon 
  appeared 
  

   in 
  large 
  numbers 
  in 
  July, 
  and 
  a 
  few 
  were 
  observed 
  spawning 
  the 
  latter 
  

   part 
  of 
  the 
  month. 
  The 
  first 
  eggs 
  were 
  obtained 
  on 
  August 
  11, 
  and 
  

   the 
  collections 
  were 
  continued 
  until 
  September 
  12, 
  during 
  which 
  time 
  

   2,600,000 
  were 
  secured 
  from 
  492 
  females; 
  2,340,000 
  of 
  them 
  were 
  trans- 
  

   ferred 
  to 
  Clackamas, 
  and 
  the 
  remainder 
  were 
  hatched 
  and 
  liberated 
  in 
  

   the 
  Salmon 
  Kiver 
  during 
  the 
  month 
  of 
  November. 
  The 
  supply 
  of 
  

   water 
  failed 
  during 
  the 
  season, 
  and 
  it 
  became 
  necessary 
  to 
  place 
  part 
  

   of 
  the 
  hatching-troughs 
  in 
  a 
  narrow 
  channel, 
  where 
  they 
  were 
  supplied 
  

   with 
  water 
  conducted 
  through 
  a 
  short 
  flume 
  from 
  the 
  bottom 
  of 
  the 
  

   river. 
  Wooden 
  covers 
  were 
  provided 
  for 
  each 
  trough 
  to 
  i)rotect 
  the 
  

   eggs, 
  and 
  canvas, 
  stretched 
  on 
  poles, 
  shaded 
  them 
  from 
  sunlight. 
  The 
  

   heavy 
  rains 
  in 
  November 
  caused 
  a 
  freshet 
  in 
  the 
  river, 
  which 
  neces- 
  

   sitated 
  the 
  removal 
  of 
  the 
  hatching 
  apparatus 
  to 
  higher 
  ground. 
  

  

  Little 
  White 
  Salmon 
  River 
  Station, 
  Washington. 
  

  

  After 
  the 
  examination 
  of 
  a 
  number 
  of 
  localities 
  on 
  the 
  Columbia 
  and 
  

   its 
  tributaries 
  by 
  Prof. 
  B. 
  W. 
  Evermann, 
  two 
  sites 
  were 
  recommended 
  

   for 
  establishment 
  of 
  auxiliary 
  stations, 
  one 
  on 
  the 
  Washington 
  shore 
  

   of 
  the 
  Columbia 
  opposite 
  the 
  Cascades, 
  and 
  the 
  other 
  just 
  below 
  Celilo, 
  

   on 
  the 
  Oregon 
  side. 
  At 
  the 
  Cascades 
  Mr. 
  George 
  Stevenson, 
  of 
  Van- 
  

   couver, 
  offered 
  to 
  furnish 
  all 
  the 
  fish 
  required 
  free 
  of 
  charge, 
  with 
  the 
  

   free 
  use 
  of 
  the 
  land 
  and 
  water 
  controlled 
  by 
  him, 
  and 
  a 
  house 
  for 
  the 
  

   employees. 
  It 
  was 
  proposed 
  to 
  capture 
  the 
  fish 
  by 
  means 
  of 
  scow 
  wheels 
  

   and 
  hold 
  them 
  until 
  ripe 
  in 
  a 
  narrow 
  channel 
  between 
  the 
  island 
  on 
  

   which 
  the 
  wheels 
  are 
  located 
  and 
  the 
  main 
  shore. 
  The 
  superintendent 
  

   was 
  instructed 
  to 
  make 
  the 
  necessary 
  arrangements, 
  but 
  before 
  under- 
  

   taking 
  the 
  work 
  an 
  attempt 
  was 
  made 
  to 
  transfer 
  the 
  fish 
  from 
  the 
  

   wheels 
  to 
  the 
  channel. 
  The 
  results 
  attained 
  were 
  so 
  poor 
  that 
  the 
  site 
  

   was 
  abandoned. 
  The 
  question 
  of 
  establishing 
  a 
  station 
  at 
  the 
  other 
  

   site, 
  near 
  Celilo, 
  was 
  also 
  considered, 
  but 
  it 
  was 
  given 
  up 
  as 
  imprac- 
  

   ticable, 
  in 
  view 
  of 
  the 
  fact 
  that 
  it 
  would 
  be 
  necessary 
  to 
  transfer 
  the 
  

   fish 
  some 
  distance 
  from 
  the 
  seines 
  to 
  the 
  retaining 
  pond. 
  

  

  As 
  it 
  was 
  believed 
  that 
  the 
  streams 
  in 
  the 
  vicinity 
  of 
  the 
  Cascades 
  

   aflbrded 
  the 
  principal 
  spawning-grounds 
  of 
  the 
  quinnat 
  salmon, 
  fur- 
  

   ther 
  investigations 
  w^ere 
  made, 
  and 
  as 
  a 
  result 
  the 
  Little 
  White 
  Salmon 
  

   w 
  as 
  favorably 
  reported 
  on 
  by 
  the 
  superintendent 
  and 
  Mr. 
  Evermann. 
  

   This 
  stream 
  empties 
  into 
  the 
  Columbia 
  about 
  14 
  miles 
  above 
  the 
  Cas- 
  

   cades, 
  and 
  the 
  point 
  selected 
  for 
  the 
  establishment 
  of 
  the 
  station 
  is 
  

   about 
  a 
  half 
  mile 
  from 
  its 
  mouth. 
  Immediately 
  after 
  the 
  site 
  had 
  been 
  

   chosen, 
  steps 
  were 
  taken 
  to 
  erect 
  a 
  rack 
  across 
  the 
  river 
  and 
  to 
  con- 
  

   struct 
  a 
  hatchery 
  and 
  a 
  mess-house 
  for 
  the 
  men. 
  Mr. 
  W. 
  P. 
  Sauerhoff, 
  

   who 
  had 
  been 
  detailed 
  to 
  assist 
  the 
  superintendent, 
  arrived 
  on 
  the 
  

   grounds 
  by 
  September 
  21, 
  and 
  by 
  September 
  26 
  work 
  had 
  progressed 
  

   far 
  enough 
  to 
  commence 
  the 
  collection 
  of 
  eggs. 
  Eggs 
  were 
  taken 
  daily
