  This 
  is 
  a 
  shaly 
  limestone 
  with 
  

   bands 
  of 
  shale. 
  The 
  limestone 
  is 
  

   fossiliferous 
  and 
  contains 
  several 
  

   bands 
  of 
  very 
  lean 
  ore, 
  with 
  many 
  

   crinoid 
  stems.

  Light 
  and

  shale, 
  with 
  few

  limestone. 
  At 
  171 
  feet 
  

   there 
  is 
  a 
  4 
  inch 
  band 
  with 
  black 
  

   pebbles.

  Some

  Shales

   Both 
  contain

  Soft, 
  very 
  dark 
  shale 
  with 
  a 
  

   few 
  bands 
  of 
  a 
  lighter 
  color. 
  

  

  Oolitic 
  ore, 
  with 
  fragments 
  of 
  

   bryozoans. 
  

  

  This 
  is 
  a 
  dark 
  shale 
  dividing 
  

   the 
  ore. 
  

  

  Coarse 
  grained 
  ore, 
  associated 
  

   with 
  calcareous 
  sandstone. 
  

  

  The 
  upper 
  4 
  inches 
  is 
  a 
  band 
  of 
  

   shale 
  with 
  2 
  inches 
  at 
  middle 
  of 
  a 
  

   conglomeratic 
  nature. 
  The 
  basal 
  

   6 
  inches 
  is 
  a 
  white 
  sandstone. 
  

   The 
  remaining 
  portion 
  contains 
  

   thin 
  layers 
  of 
  mottled, 
  dark, 
  

   sandy 
  shale. 
  Some 
  of 
  the 
  sand- 
  

   stone 
  has 
  a 
  reddish 
  tinge 
  showing 
  

   faint 
  traces 
  of 
  ore. 
  

  

  This 
  hole 
  was 
  intended 
  to 
  test 
  the 
  long 
  stretch 
  between 
  

   Brewerton 
  and 
  Verona 
  throughout 
  which 
  the 
  Clinton 
  forma- 
  

   t'on 
  is 
  mostly 
  concealed. 
  The 
  results 
  indicate 
  some 
  similarity 
  of 
  

   conditions 
  in 
  regard 
  to 
  ore 
  deposition 
  with 
  the 
  section 
  at 
  Brewer- 
  

   ton 
  and 
  also 
  with 
  that 
  at 
  Clinton, 
  but 
  the 
  oolitic 
  bed 
  is 
  much
