  Well

  — 
  Only 
  very 
  shallow 
  wells 
  have 
  been 
  sunk 
  in 
  the 
  

   upland 
  fiats 
  and 
  of 
  these 
  we 
  have 
  only 
  very 
  incomplete 
  records. 
  

   They, 
  however, 
  agree 
  in 
  finding 
  occasional 
  fresh 
  water 
  mussels 
  

   {JJjiionidce) 
  . 
  The 
  well 
  diggers 
  are 
  quite 
  positive 
  that 
  they 
  were 
  

   exactly 
  like 
  the 
  shells 
  now 
  living 
  in 
  the 
  adjoining 
  lakes.

  A 
  well 
  digger 
  living 
  just 
  north 
  of 
  Wallace 
  lake 
  reported 
  that 
  in 
  

   a 
  strip 
  of 
  country 
  about 
  two 
  miles 
  wide, 
  just 
  north 
  of 
  the 
  lake, 
  

   he 
  had 
  found 
  " 
  mussel 
  shells 
  " 
  at 
  depths 
  from 
  18 
  to 
  30 
  feet 
  in 
  all 
  

   but 
  two 
  wells. 
  Shells 
  were 
  very 
  abundant 
  in 
  a 
  well 
  on 
  the 
  Pat- 
  

   terson

   The 
  well 
  was 
  sunk 
  on 
  an 
  outlying 
  hill 
  45 
  feet 
  above 
  the 
  level 
  of 
  

   of 
  Wallace 
  lake. 
  The 
  shells 
  were 
  found 
  at 
  a 
  depth 
  of 
  20 
  feet. 
  

   In 
  a 
  well 
  sunk 
  on 
  the 
  Eittle 
  place 
  a 
  great 
  many 
  shells 
  were 
  found 
  

   between 
  25 
  and 
  30 
  feet. 
  The 
  old 
  dump 
  heap 
  at 
  the 
  Patterson 
  

   place 
  was 
  examined 
  and 
  a 
  few 
  fragments 
  of 
  U?nos 
  found. 
  As 
  it 
  

   was 
  possible 
  for 
  these 
  to 
  have 
  been 
  scattered 
  there 
  since 
  the 
  dig-

  well

  can 
  not 
  be 
  considered 
  conclusive. 
  

  

  Colored

  clays.

  Where 
  large 
  sections 
  of 
  these 
  beds 
  

   are 
  to 
  be 
  seen 
  along 
  the

  very 
  heavy 
  beds

  colored 
  sands

  clays

  calcareous 
  concretions

  to 
  

   be

  This 
  is 
  especially 
  noticeable 
  near
