﻿MUSSELS

  The 
  culls 
  were 
  mostly 
  razorbacks, 
  spikes, 
  such 
  of 
  the 
  black 
  sand 
  

   shells 
  as 
  have 
  a 
  pmk 
  nacre, 
  and 
  a 
  few 
  floaters. 
  By 
  count 
  about 
  half 
  

   of 
  the 
  commercial 
  shells 
  obtained 
  are 
  fat 
  muckets 
  (luteola), 
  while 
  

   by 
  weight 
  they 
  form 
  only 
  40 
  per 
  cent 
  of 
  the 
  entire 
  catch. 
  

  

  A 
  large 
  number 
  of 
  fine 
  pearls 
  have 
  been 
  found 
  here, 
  nearly 
  all 
  of 
  

   which 
  come 
  from 
  the 
  luteolas. 
  One 
  of 
  these 
  found 
  just 
  before 
  our 
  

   visit 
  sold 
  for 
  $300, 
  and 
  another 
  for 
  $150. 
  The 
  fishermen 
  reported 
  

   the 
  pearls 
  not 
  as 
  numerous 
  as 
  during 
  the 
  previous 
  year. 
  They 
  also 
  

   reported 
  another 
  curious 
  fact, 
  that 
  shells 
  with 
  pearls 
  run 
  along 
  cer- 
  

   tain 
  ridges 
  on 
  the 
  lake 
  bottom 
  and 
  are 
  not 
  found 
  in 
  the 
  hollows 
  along 
  

   either 
  side 
  of 
  the 
  ridge. 
  

  

  In 
  view 
  of 
  these 
  facts 
  it 
  would 
  seem 
  advisable 
  to 
  propagate 
  arti- 
  

   ficially 
  the 
  local 
  commercial 
  species, 
  especially 
  these 
  thick-shelled 
  

   luteolas, 
  and 
  to 
  use 
  this 
  locahty 
  as 
  a 
  som'ce 
  from 
  which 
  to 
  introduce 
  

   desirable 
  species 
  into 
  other 
  lakes 
  and 
  rivers. 
  

  

  Mr. 
  Andy 
  Noel, 
  a 
  shell 
  buyer 
  for 
  the 
  Wisconsin 
  Button 
  Co. 
  at 
  

   La 
  Crosse, 
  took 
  us 
  around 
  the 
  lake 
  and 
  showed 
  us 
  every 
  courtesy 
  

   in 
  the 
  way 
  of 
  obtaining 
  samples 
  and 
  data. 
  Our 
  sincere 
  thanks 
  are 
  

   hereby 
  acknowledged 
  for 
  these 
  kind 
  attentions. 
  

  

  PLEASANT 
  AND 
  CLEARWATER 
  LAKES. 
  

  

  These 
  lakes 
  are 
  situated 
  near 
  i^nandale, 
  in 
  Wright 
  County, 
  and 
  

   are 
  connected 
  by 
  the 
  Clearwater 
  River 
  with 
  the 
  Mississippi. 
  Pleasant 
  

   Lake, 
  right 
  in 
  the 
  edge 
  of 
  the 
  town, 
  is 
  2 
  J 
  miles 
  long 
  and 
  1 
  mile 
  wide, 
  

   with 
  a 
  gravelly 
  and 
  sandy 
  bottom, 
  comparatively 
  free 
  from 
  vegeta- 
  

   tion. 
  Shells 
  of 
  the 
  pocketbook 
  (ventricosa) 
  and 
  Anodonta 
  pepiniana 
  

   were 
  obtained 
  here. 
  The 
  former 
  proved 
  to 
  be 
  excellent 
  button 
  

   material, 
  but 
  was 
  very 
  scarce. 
  It 
  was 
  reported, 
  however, 
  to 
  have 
  

   been 
  abundant 
  during 
  the 
  previous 
  year, 
  but 
  had 
  been 
  killed 
  or 
  driven 
  

   into 
  deeper 
  water 
  by 
  the 
  ice. 
  

  

  Clearwater 
  Lake 
  is 
  4 
  miles 
  from 
  town 
  and 
  is 
  much 
  larger 
  than 
  

   Pleasant 
  Lake, 
  being 
  7 
  J 
  miles 
  long 
  and 
  IJ 
  miles 
  wide. 
  The 
  south- 
  

   eastern 
  end 
  of 
  the 
  lake 
  is 
  wider 
  and 
  deeper 
  and 
  has 
  rocky 
  shores; 
  

   the 
  northwestern 
  half 
  is 
  narrower, 
  shallower, 
  and 
  so 
  lined 
  with 
  reeds 
  

   and 
  rushes 
  that 
  it 
  is 
  impossible 
  to 
  get 
  anywhere 
  near 
  the 
  shore 
  in 
  

   most 
  places. 
  

  

  The 
  fat 
  mucket 
  (luteola) 
  was 
  found 
  here, 
  in 
  addition 
  to 
  the 
  jjocket- 
  

   book 
  and 
  A. 
  pejnniana. 
  Both 
  the 
  mucket 
  and 
  the 
  pocketbook 
  

   are 
  large 
  and 
  thick 
  and 
  make 
  excellent 
  button 
  material. 
  

  

  The 
  Clearwater 
  River 
  flows 
  through 
  the 
  lake 
  and 
  was 
  reported 
  

   to 
  be 
  fuU 
  of 
  fine 
  shells. 
  This 
  lake 
  and 
  river 
  would 
  yield 
  a 
  carload 
  

   of 
  fii'st 
  grade 
  mussels, 
  which 
  could 
  be 
  readily 
  floated 
  down 
  to 
  the 
  

   town 
  of 
  Clearwater, 
  on 
  the 
  bank 
  of 
  the 
  Mississippi, 
  and 
  shipped 
  from 
  

   there. 
  Also 
  the 
  local 
  species 
  might 
  well 
  be 
  propagated 
  at 
  the 
  lower 
  

   end 
  of 
  the 
  lake 
  and 
  in 
  the 
  river, 
  while 
  in 
  the 
  muddier 
  bottom 
  at 
  the
