  erally 
  regarded 
  as 
  abundant 
  in 
  the 
  river. 
  Fishermen 
  generally 
  speak 
  

   of 
  it 
  as 
  uncommon, 
  and 
  yet 
  informants 
  sometimes 
  refer 
  to 
  occasions 
  

   when 
  they 
  were 
  taken 
  plentifully 
  about 
  the 
  ends 
  of 
  wing 
  dams. 
  It 
  

   has 
  been 
  supposed, 
  therefore, 
  that 
  the 
  fish 
  is 
  more 
  abundant 
  than 
  

   common 
  observations 
  indicate, 
  but 
  that 
  it 
  migrates 
  rapidly, 
  keeping 
  

   in 
  the 
  current 
  where 
  fishermen 
  work 
  least, 
  and 
  tarrying 
  where 
  the 
  

   water 
  runs 
  swiftly 
  around 
  such 
  obstructions 
  as 
  the 
  wing 
  dams. 
  This 
  

   supposition 
  seemed 
  to 
  receive 
  confirmation 
  from 
  the 
  observations 
  at 
  

   Keokuk 
  in 
  1913. 
  

  

  The 
  question 
  still 
  occurred: 
  Would 
  the 
  herring 
  be 
  found 
  in 
  the 
  

   upper 
  river 
  after 
  the 
  dam 
  was 
  constructed 
  ? 
  On 
  the 
  occasion 
  of 
  a 
  

   visit 
  by 
  the 
  writer 
  to 
  Lake 
  Pepin 
  in 
  Minnesota 
  on 
  July 
  19, 
  1913, 
  a 
  

   single 
  specimen 
  was 
  taken 
  in 
  a 
  seine 
  haul 
  of 
  our 
  propagation 
  crew. 
  

   Several 
  fishermen 
  were 
  positive 
  that 
  this 
  was 
  the 
  first 
  specimen 
  seen 
  

   in 
  Lake 
  Pepin 
  in 
  that 
  season. 
  The 
  foreman 
  of 
  the 
  crew, 
  Mr. 
  William 
  

   Teachout, 
  was 
  requested 
  to 
  report 
  each 
  subsequent 
  catch, 
  and 
  follow- 
  

   ing 
  is 
  a 
  record 
  of 
  his 
  reports. 
  To 
  check 
  the 
  field 
  identifications, 
  

   specimens 
  were 
  sent 
  to 
  the 
  Fairport 
  laboratory 
  from 
  time 
  to 
  time, 
  

   and 
  in 
  each 
  case 
  the 
  identification 
  was 
  confirmed. 
  The 
  seining 
  oper- 
  

   ations 
  were 
  discontinued 
  in 
  Lake 
  Pepin 
  after 
  September 
  1 
  1 
  , 
  though 
  

   pursued 
  in 
  the 
  river 
  below 
  the 
  lake. 
  Later 
  hauls 
  in 
  Lake 
  Pepin 
  

   were 
  made 
  October 
  17, 
  18, 
  and 
  23, 
  without 
  further 
  catch 
  of 
  herring.

  The 
  observations 
  at 
  Lake 
  Pepin 
  were 
  continued 
  after 
  the 
  seining 
  

   operations 
  began 
  in 
  Lake 
  Pepin 
  in 
  1914. 
  A 
  single 
  specimen 
  was 
  

   taken 
  May 
  12, 
  a 
  few 
  about 
  the 
  middle 
  of 
  June, 
  after 
  which 
  they 
  were 
  

   taken 
  more 
  plentifully, 
  especially 
  in 
  July, 
  as 
  shown
