  upper 
  end 
  of 
  the 
  lake 
  it 
  is 
  ])rol)able 
  that 
  some 
  of 
  the 
  pig-toes 
  (Quad- 
  

   j'ula) 
  would 
  thrive 
  well. 
  

  

  It 
  is 
  very 
  doubtful 
  whether 
  any 
  recommendations 
  can 
  be 
  made 
  for 
  

   Pleasant 
  Lake. 
  

  

  PULASKI, 
  BUFFALO, 
  RICE, 
  AND 
  KORONIS 
  LAKES. 
  

  

  These 
  four 
  lakes 
  are 
  connected 
  with 
  the 
  Crow 
  River, 
  but 
  the 
  out- 
  

   lets 
  are 
  very 
  small 
  streams, 
  and 
  those 
  of 
  the 
  first 
  two 
  are 
  open 
  only 
  

   dm'ing 
  spring 
  freshets. 
  

  

  Lake 
  Pulaski 
  is 
  nearly 
  circular 
  in 
  outline, 
  about 
  1^ 
  miles 
  in 
  diam- 
  

   eter, 
  with 
  a 
  bottom 
  composed 
  of 
  gravel 
  and 
  sand, 
  covered 
  with 
  a 
  

   heavy 
  growth 
  of 
  CTiara, 
  Potomageton, 
  and 
  algae. 
  

  

  Buffalo 
  Lake 
  is 
  2^ 
  miles 
  long 
  and 
  1 
  mile 
  wide, 
  with 
  a 
  maximum 
  

   depth 
  of 
  50 
  to 
  60 
  feet. 
  There 
  are 
  two 
  shallow 
  bars 
  across 
  the 
  center 
  

   of 
  the 
  lake 
  wliich 
  are 
  covered 
  with 
  rushes, 
  and 
  the 
  bottom 
  is 
  firm 
  

   sand 
  and 
  gravel, 
  with 
  very 
  little 
  vegetation. 
  

  

  Rice 
  Lake, 
  6 
  miles 
  northeast 
  of 
  Paynesville 
  in 
  Stearns 
  County, 
  is 
  3 
  

   miles 
  long 
  by 
  2 
  miles 
  wide. 
  The 
  bottom 
  is 
  composed 
  of 
  much 
  coarser 
  

   gravel 
  than 
  in 
  Buffalo 
  Lake, 
  and 
  there 
  is 
  a 
  little 
  more 
  CTiara 
  and 
  

   algse. 
  The 
  north 
  fork 
  of 
  the 
  Crow 
  River 
  runs 
  into 
  the 
  southwest 
  

   corner 
  of 
  this 
  lake 
  and 
  empties 
  out 
  again 
  within 
  a 
  short 
  distance. 
  

  

  Koronis 
  Lake, 
  2 
  miles 
  southeast 
  of 
  Paynesville, 
  is 
  3^ 
  miles 
  long 
  

   and 
  2 
  miles 
  wide, 
  with 
  a 
  very 
  irregular 
  and 
  precipitous 
  shore. 
  The 
  

   bottom 
  contains 
  much 
  more 
  sand 
  than 
  gravel 
  and 
  the 
  vegetation 
  

   is 
  very 
  limited 
  except 
  at 
  the 
  inlet 
  and 
  outlet. 
  

  

  The 
  fat 
  mucket 
  (luteola) 
  and 
  Anodonta 
  jjepiniana 
  were 
  found 
  in 
  all 
  

   four 
  lakes, 
  and 
  in 
  addition 
  Anodontoides 
  ferussacianus 
  jnodestus 
  was 
  

   found 
  in 
  Buffalo 
  and 
  Koronis 
  Lakes. 
  Most 
  of 
  these 
  muckets 
  are 
  

   dwarfed, 
  as 
  is 
  usual 
  in 
  a 
  lake, 
  and 
  thin-shelled, 
  but 
  those 
  from 
  Rice 
  

   Lake 
  are 
  full 
  size, 
  of 
  good 
  thickness 
  and 
  have 
  a 
  fair 
  luster, 
  and 
  were 
  

   classed 
  as 
  first-grade 
  shells. 
  

  

  The 
  Anodontas 
  were 
  found 
  in 
  regular 
  windrows 
  10 
  or 
  15 
  feet 
  from 
  

   shore, 
  and 
  outside 
  of 
  them 
  were 
  the 
  luteolas, 
  in 
  water 
  shallow 
  enough 
  

   to 
  obtain 
  them 
  by 
  wading. 
  The 
  epidermis 
  of 
  these 
  luteolas 
  was 
  a 
  

   dark 
  straw-yellow, 
  and 
  was 
  highly 
  polished 
  like 
  that 
  of 
  the 
  same 
  

   species 
  from 
  Lake 
  Henry 
  (p. 
  11). 
  

  

  The 
  comparative 
  paucity 
  of 
  shejls 
  in 
  these 
  lakes 
  is 
  easily 
  explained 
  

   by 
  the 
  fact 
  that 
  fish 
  can 
  not 
  run 
  into 
  them 
  freely 
  at 
  the 
  time 
  of 
  year 
  

   when 
  they 
  are 
  infested 
  with 
  glochidia. 
  The 
  conditions 
  in 
  Buffalo 
  

   Lake 
  are 
  excellent 
  for 
  sand-shells 
  and 
  species 
  wliich 
  frequent 
  shallow 
  

   bars. 
  The 
  thick-shelled 
  luteolas 
  from 
  Pokegama 
  Lake 
  (Pine 
  County) 
  , 
  

   or 
  Lake 
  Pepin 
  would 
  undoubtedly 
  thrive 
  in 
  Rice 
  and 
  Koronis 
  Lakes. 
  

   Lake 
  Pulaski 
  is 
  not 
  worth 
  stocking 
  with 
  any 
  kind 
  of 
  shells. 
  

  

  Each 
  of 
  these 
  lakes 
  contains 
  an 
  abundance 
  of 
  perch, 
  bass, 
  sunfish, 
  

   crappies, 
  and 
  wall-eyed 
  pike, 
  which 
  could 
  be 
  seined 
  with 
  little 
  trouble
