  From 
  the 
  top 
  of 
  this 
  ledge 
  for 
  135 
  feet 
  to 
  the 
  schoolhouse 
  at 
  

   the 
  road 
  corners 
  there 
  are 
  occasional 
  outcrops 
  of 
  arenaceous 
  

   shales, 
  and 
  then 
  for 
  305 
  feet 
  along 
  the 
  road 
  and 
  brook 
  the 
  rocks 
  

   are 
  mostly 
  covered. 
  By 
  the 
  side 
  of 
  the 
  highway 
  just 
  above 
  the 
  

   house 
  of 
  Mr 
  George 
  P. 
  Bouck 
  and 
  about 
  one 
  mile 
  above

   road 
  is 
  an 
  outcrop 
  of 
  from 
  eight 
  to

  feet 
  of 
  Hamilton 
  shales 
  

   (C

  Those 
  at 
  the 
  base 
  are 
  rather 
  fine 
  but 
  the 
  upper 
  ones 
  are 
  

   coarser. 
  The 
  shales 
  are 
  mainly 
  argillaceous 
  and 
  contain 
  numer- 
  

   ous 
  Hamilton 
  fossils.

  while 
  a 
  little

  are 
  some 
  thin 
  layers 
  of 
  concretionary
