  REPORT 
  OF

  AND 
  FISHERIES. 
  

  

  and 
  died. 
  Fifty 
  adults 
  were 
  then 
  collected 
  from 
  the 
  Maquoketa 
  River 
  

   and 
  placed 
  in 
  Pond 
  X, 
  but 
  they 
  were 
  captured 
  too 
  late 
  in 
  the 
  season 
  to 
  

   spawn. 
  

  

  On 
  March 
  9 
  unusually 
  high 
  water 
  in 
  the 
  spring 
  branch 
  flooded 
  the 
  

   lowlands 
  east 
  of 
  the 
  superintendent's 
  residence. 
  The 
  water 
  rose 
  a 
  foot 
  

   above 
  the 
  floor 
  of 
  the 
  wagon 
  bridge, 
  doing 
  considerable 
  damage 
  to 
  the 
  

   stone 
  abutments 
  and 
  causing 
  numerous 
  washouts 
  along 
  the 
  pond 
  site. 
  

   The 
  water 
  supply 
  to 
  the 
  hatchery 
  and 
  ponds 
  was 
  cut 
  off 
  by 
  the 
  wash- 
  

   ing 
  out 
  of 
  the 
  14 
  inch 
  pipe, 
  but 
  the 
  eggs 
  and 
  fry 
  were 
  saved 
  by 
  promptly 
  

   repairing 
  it. 
  Later 
  in 
  the 
  season 
  considerable 
  work 
  was 
  done 
  with 
  the 
  

   view 
  to 
  protecting 
  the 
  supply 
  pipe 
  and 
  ponds 
  from 
  damage 
  by 
  future 
  

   freshets. 
  Owing 
  to 
  changes 
  in 
  the 
  plans 
  and 
  to 
  damage 
  done 
  by 
  the 
  

   freshet 
  and 
  the 
  cyclone 
  of 
  the 
  previous 
  year, 
  the 
  appropriation 
  for 
  the 
  

   construction 
  of 
  the 
  station 
  proved 
  inadequate, 
  hence 
  work 
  had 
  to 
  be 
  

   stopi)ed 
  in 
  the 
  spring, 
  pending 
  an 
  additional 
  appropriation 
  of 
  $4,200, 
  

   submitted 
  in 
  the 
  deficiency 
  bill. 
  

  

  DuLUTH 
  Station, 
  Minnesota 
  (S. 
  P. 
  Wires, 
  Superintendent). 
  

  

  Early 
  in 
  the 
  summer 
  the 
  usual 
  arrangements 
  were 
  made 
  for 
  collecting 
  

   lake-trout 
  and 
  whitefish 
  eggs 
  from 
  the 
  waters 
  of 
  Lake 
  Superior. 
  The 
  

   lake-trout 
  season 
  commenced 
  September 
  15 
  and 
  closed 
  N^ovember 
  7, 
  

   resulting 
  in 
  a 
  collection 
  of 
  5,874,000 
  eggs 
  from 
  the 
  following 
  points: 
  

   Ross 
  Port, 
  Ontario, 
  2,203,000; 
  St. 
  Ignace 
  Island, 
  Ontario, 
  800,000; 
  Isle 
  

   Royale, 
  Mich., 
  1,701,000; 
  Grand 
  Portage, 
  Minn., 
  410,000; 
  French 
  River, 
  

   Minn., 
  40,000; 
  Bayfield, 
  Wis., 
  690,000; 
  Pueblo 
  River, 
  Ontario, 
  30,000. 
  

   They 
  were 
  transferred 
  to 
  the 
  station 
  and 
  4,768,000 
  fry 
  were 
  hatched 
  

   from 
  them 
  and 
  distributed 
  during 
  April, 
  May, 
  and 
  June. 
  

  

  The 
  whitefish 
  collections 
  commenced 
  at 
  Basswood 
  Lake, 
  Minn., 
  on 
  

   October 
  17 
  and 
  the 
  total 
  take 
  of 
  eggs 
  during 
  the 
  season 
  amounted 
  to 
  

   4,200,000. 
  The 
  loss 
  during 
  incubation 
  was 
  very 
  heavy, 
  owing 
  partly 
  

   to 
  unfavorable 
  weather 
  conditions 
  which 
  prevailed 
  during 
  the 
  collecting 
  

   season 
  and 
  partly 
  to 
  the 
  fact 
  that 
  it 
  was 
  necessary 
  to 
  transport 
  the 
  

   eggs 
  long 
  distances 
  over 
  rough 
  roads 
  by 
  wagon 
  from 
  the 
  fishing-grounds 
  

   to 
  the 
  railroad 
  station. 
  As 
  the 
  result 
  of 
  the 
  season's 
  work 
  1,990,000 
  

   fry 
  were 
  deposited 
  at 
  Grace 
  Harbor, 
  Isle 
  Royale, 
  Michigan, 
  on 
  April 
  29. 
  

  

  In 
  addition 
  to 
  the 
  collections 
  made 
  by 
  the 
  station 
  force 
  25,000 
  brook, 
  

   21,450 
  rainbow, 
  and 
  100,000 
  steelhead 
  trout 
  eggs 
  were 
  transferred 
  from 
  

   other 
  stations 
  to 
  be 
  hatched 
  and 
  distributed 
  from.Duluth. 
  The 
  brook- 
  

   trout 
  eggs 
  yielded 
  15,400 
  fry, 
  which 
  were 
  furnished 
  to 
  applicants 
  in 
  

   Minnesota 
  and 
  North 
  Dakota 
  during 
  May 
  and 
  June. 
  The 
  rainbow 
  

   eggs 
  were 
  in 
  excellent 
  condition 
  when 
  received, 
  but 
  they 
  proved 
  almost 
  

   a 
  total 
  loss, 
  probably 
  because 
  of 
  the 
  difference 
  in 
  the 
  temperature 
  of 
  

   the 
  water 
  at 
  Neosho, 
  where 
  they 
  were 
  eyed, 
  and 
  Duluth. 
  The 
  tem- 
  

   perature 
  at 
  Duluth 
  during 
  the 
  hatching 
  period 
  was 
  below 
  34° 
  F., 
  whereas 
  

   at 
  Neosho 
  it 
  is 
  57°. 
  The 
  steelhead 
  eggs 
  produced 
  75,000 
  fry, 
  which 
  

   were 
  deposited 
  during 
  July 
  in 
  tributaries 
  of 
  Lake 
  Superior. 
  A 
  number 
  

   of 
  specimens 
  of 
  that 
  species 
  have 
  been 
  captured 
  in 
  French 
  and 
  Lester
