  is 
  an 
  exposure 
  twenty-five 
  feet 
  below 
  the 
  summit, 
  

   where 
  occurs 
  a 
  calcareous 
  layer 
  largely 
  composed 
  of 
  crinoidal 
  

   remains 
  ; 
  the 
  inclosing 
  shales 
  bear 
  their 
  fossils 
  in 
  thin 
  separated 
  

   layers, 
  and 
  in 
  places 
  contain 
  very 
  large 
  irregular 
  concretions.

  concretions, 
  

   overlaid 
  by 
  shaly 
  sandstones 
  and 
  thin 
  sandstone 
  benches 
  to 
  top. 
  

   The 
  entire 
  thickness 
  of 
  the 
  exposure 
  is 
  about 
  fifty 
  feet. 
  Fossils 
  

   occur 
  as 
  in 
  section 
  K 
  and 
  are 
  abundant 
  in 
  all 
  the 
  shaly 
  strata. 
  

  

  This 
  quarry 
  was 
  opened 
  at 
  the 
  time 
  the 
  canal 
  was 
  put 
  through 
  

   and 
  has 
  long 
  been 
  abandoned.

  below 
  the 
  similar 
  stratum 
  observed
