  COMMISSIONER 
  OF 
  FISH 
  AND 
  FISHERIES. 
  

  

  spawuing-beds, 
  be 
  built 
  south 
  of 
  the 
  reservoir. 
  With 
  the 
  view 
  to 
  

   increasing 
  the 
  supply 
  of 
  water 
  for 
  the 
  hatchery 
  a 
  3iuch 
  artesian 
  well 
  

   was 
  sunk 
  during 
  the 
  month 
  of 
  April. 
  At 
  a 
  depth 
  of 
  96h 
  feet 
  a 
  tiow 
  of 
  

   14 
  gallons 
  per 
  minute 
  was 
  obtained, 
  the 
  temperature 
  being 
  50°. 
  There 
  

   has 
  been 
  no 
  opportunity 
  to 
  test 
  the 
  value 
  of 
  this 
  water 
  for 
  hatching- 
  

   purposes, 
  but 
  it 
  was 
  tried 
  on 
  a 
  trough 
  containing 
  23 
  brook 
  trout 
  for 
  

   one 
  week. 
  During 
  this 
  time 
  the 
  fish 
  did 
  not 
  thrive. 
  Their 
  gills 
  became 
  

   affected 
  and 
  they 
  refused 
  to 
  take 
  food. 
  Whether 
  this 
  was 
  due 
  to 
  the 
  

   fact 
  that 
  the 
  temperature 
  of 
  the 
  water 
  was 
  much 
  lower 
  than 
  that 
  of 
  

   the 
  spring 
  water, 
  or 
  to 
  the 
  presence 
  of 
  injurious 
  foreign 
  matter, 
  can 
  

   not 
  be 
  determined. 
  The 
  water 
  had 
  a 
  slight 
  taste 
  of 
  iron, 
  but 
  a 
  chemical 
  

   analysis 
  developed 
  the 
  fact 
  that 
  it 
  was 
  not 
  in 
  sufficient 
  quantities 
  to 
  

   prove 
  injurious. 
  By 
  mingling 
  it 
  with 
  spring 
  or 
  creek 
  water 
  good 
  

   results 
  were 
  secured. 
  

  

  An 
  appropriation 
  of 
  $13,000 
  having 
  been 
  made 
  by 
  Congress 
  for 
  the 
  

   construction 
  of 
  a 
  new 
  hatchery, 
  a 
  dwelling 
  for 
  the 
  superintendent, 
  

   and 
  the 
  increase 
  of 
  the 
  spring-water 
  supply, 
  the 
  superintendent 
  was 
  

   instructed 
  in 
  June 
  to 
  submit 
  the 
  necessary 
  plans 
  and 
  specifications. 
  

  

  At 
  the 
  close 
  of 
  the 
  year 
  the 
  stock 
  of 
  fish 
  on 
  hand 
  was 
  as 
  follows: 
  

  

  Alpena 
  Station, 
  Michigan 
  (F. 
  N. 
  Clark, 
  Superintendent). 
  

  

  , 
  The 
  foreman 
  of 
  the 
  station, 
  Mr. 
  H. 
  D. 
  Dean, 
  having 
  been 
  appointed 
  

   superintendent 
  of 
  the 
  station 
  at 
  Cape 
  Vincent, 
  N. 
  Y., 
  the 
  position 
  

   thus 
  made 
  vacant 
  was 
  filled 
  by 
  the 
  promotion 
  of 
  S. 
  W. 
  Downing, 
  fish- 
  

   culturist. 
  Arrangements 
  were 
  perfected 
  during 
  the 
  month 
  of 
  August 
  

   for 
  the 
  collection 
  of 
  lake-trout 
  and 
  whitetish 
  eggs, 
  and 
  in 
  October 
  a 
  

   large 
  force 
  of 
  spawn-takers 
  was 
  employed 
  and 
  stationed 
  at 
  all 
  of 
  the 
  

   important 
  fishing-grounds 
  in 
  the 
  upper 
  waters 
  of 
  lakes 
  Huron 
  and 
  

   Michigan. 
  

  

  Lake 
  fro«t— 
  Favorable 
  weather 
  and 
  an 
  unusually 
  large 
  run 
  of 
  trout 
  

   permitted 
  the 
  collection 
  of 
  over 
  7,000,000 
  eggs 
  at 
  Charlevoix 
  and 
  

   Beaver 
  Island, 
  an 
  excess 
  of 
  4,000,000 
  over 
  the 
  previous 
  year's 
  take 
  at 
  

   these 
  points. 
  On 
  account 
  of 
  the 
  frequent 
  storms 
  prevailing 
  at 
  the 
  

   Caribou 
  Islands 
  and 
  Detour, 
  where 
  collections 
  in 
  the 
  past 
  have 
  usually 
  

   been 
  large, 
  the 
  nets 
  could 
  not 
  be 
  lifted 
  regularly, 
  consequently 
  most 
  of 
  

   the 
  fish 
  taken 
  from 
  them 
  were 
  unfit 
  for 
  use. 
  The 
  eggs 
  secured 
  from 
  

   the 
  fish 
  caught 
  in 
  Lake 
  Michigan 
  were 
  forwarded 
  to 
  the 
  field 
  foreman 
  

   at 
  Charlevoix, 
  and 
  from 
  there 
  they 
  were 
  shipped 
  by 
  rail 
  to 
  Northville.
