  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  ill 
  1895. 
  Upward 
  of 
  2,000 
  were 
  observed 
  ou 
  their 
  spawning-ground 
  in 
  

   the 
  inlet 
  to 
  Altiiras 
  Lake. 
  They 
  were 
  closely 
  watclied 
  through 
  the 
  

   season 
  and 
  it 
  was 
  fouud 
  that 
  all 
  died 
  at 
  the 
  close 
  of 
  the 
  spawning 
  period. 
  

   These 
  fish 
  were 
  already 
  in 
  Alturas 
  Lake 
  when 
  the 
  observations 
  began, 
  

   July 
  10, 
  and 
  it 
  is 
  not 
  yet 
  certainly 
  known 
  whether 
  they 
  are 
  anadroDious 
  

   or 
  remain 
  permanently 
  in 
  the 
  lake. 
  

  

  TRIBUTARIES 
  OF 
  PUGET 
  SOUND. 
  

  

  In 
  1889 
  a 
  large 
  plant 
  of 
  fry 
  of 
  the 
  eastern 
  whitefish 
  (Coregomis 
  clupei- 
  

   forniis) 
  was 
  made 
  in 
  Lake 
  Washington, 
  near 
  Seattle, 
  by 
  the 
  United 
  

   States 
  Fish 
  Commission. 
  In 
  June, 
  1896, 
  Mr. 
  A. 
  B. 
  Alexander 
  devoted 
  

   a 
  short 
  time 
  to 
  a 
  series 
  of 
  examinations 
  to 
  determine 
  whether 
  any 
  of 
  

   these 
  fry 
  have 
  survived. 
  No 
  whitefish 
  were 
  found. 
  Investigations 
  

   were 
  again 
  taken 
  up 
  in 
  November 
  and 
  December, 
  1896. 
  Various 
  tests 
  

   were 
  made 
  with 
  appropriate 
  kinds 
  of 
  apparatus 
  in 
  different 
  parts 
  of 
  

   the 
  lake, 
  but 
  no 
  evidence 
  was 
  obtained 
  that 
  any 
  of 
  the 
  whitefish 
  

   remained. 
  The 
  physical 
  features 
  of 
  the 
  lake 
  were 
  carefully 
  studied, 
  

   soundings 
  were 
  made, 
  a 
  valuable 
  series 
  of 
  temperature 
  observations 
  

   was 
  recorded, 
  and 
  collections 
  of 
  the 
  fishes, 
  crustaceans, 
  and 
  other 
  

   inhabitants 
  of 
  the 
  lake 
  were 
  obtained. 
  

  

  Connected 
  with 
  Lake 
  Washington, 
  and 
  distant 
  only 
  a 
  few 
  miles, 
  are 
  

   Lakes 
  Union 
  and 
  Sammamish. 
  Mr. 
  Alexander 
  conducted 
  similar 
  inves- 
  

   tigations 
  in 
  these 
  waters, 
  studying 
  the 
  physical 
  conditions 
  and 
  making 
  

   collections 
  of 
  the 
  fishes 
  and 
  crustaceans. 
  

  

  During 
  July 
  and 
  August, 
  1896, 
  Messrs. 
  Alexander 
  and 
  Cox 
  carried 
  

   on 
  studies 
  of 
  the 
  blueback 
  or 
  sockeye 
  salmon 
  ( 
  Oncorhynchus 
  nerka) 
  in 
  

   certain 
  streams 
  flowing 
  into 
  Puget 
  Sound 
  from 
  the 
  east. 
  One 
  object 
  

   of 
  the 
  investigation 
  was 
  to 
  obtain 
  information 
  desired 
  by 
  the 
  Inter- 
  

   national 
  Joint 
  Fishery 
  Commission 
  as 
  to 
  whether 
  any 
  large 
  numbers 
  

   of 
  blueback 
  salmon 
  entering 
  Puget 
  Sound 
  ascend 
  Washington 
  rivers 
  

   for 
  the 
  purposes 
  of 
  spawning. 
  The 
  movements 
  of 
  the 
  bluebacks 
  in 
  

   the 
  region 
  of 
  the 
  San 
  Juan 
  Islands 
  were 
  studied, 
  and 
  the 
  more 
  impor- 
  

   tant 
  rivers 
  were 
  visited 
  and 
  examined, 
  among 
  them 
  being 
  the 
  Skagit, 
  

   Nooksack, 
  and 
  Stilliguamish. 
  It 
  was 
  ascertained 
  that 
  the 
  blueback 
  

   enters 
  only 
  the 
  Skagit 
  Eiver 
  in 
  noteworthy 
  numbers, 
  and 
  that 
  im- 
  

   portant 
  spawning- 
  beds 
  occur 
  in 
  Baker 
  Lake 
  and 
  Baker 
  River, 
  one 
  of 
  

   the 
  principal 
  tributaries 
  of 
  the 
  Skagit. 
  

  

  TSILTCOOS, 
  WHOAHINK, 
  AND 
  TAHKENITOH 
  LAKES, 
  OREGON. 
  

  

  These 
  are 
  small 
  lakes 
  situated 
  near 
  the 
  coast 
  a 
  few 
  miles 
  south 
  of 
  

   the 
  mouth 
  of 
  the 
  Siuslaw 
  River. 
  A 
  number 
  of 
  persons 
  living 
  in 
  the 
  

   vicinity 
  had 
  requested 
  the 
  Commission 
  to 
  stock 
  Tsiltcoos 
  Lake 
  with 
  

   black 
  bass 
  and 
  Whoahink 
  Lake 
  with 
  brook 
  trout. 
  Dr. 
  Meek, 
  who 
  was 
  

   engaged 
  in 
  experimental 
  fish-cultural 
  work 
  on 
  the 
  Siuslaw 
  River, 
  was 
  

   detailed 
  to 
  rei)ort 
  on 
  the 
  advisability 
  of 
  complying 
  with 
  the 
  requests. 
  

   The 
  biological 
  and 
  physical 
  features 
  of 
  the 
  lakes 
  were 
  studied 
  and 
  

   large 
  collections 
  were 
  made 
  of 
  the 
  native 
  fishes 
  and 
  the 
  various 
  kinds
