  Small

  imperfect 
  specimen. 
  

  

  A 
  little 
  higher 
  is 
  the 
  main 
  quarry 
  of 
  'bluish 
  sandstone 
  alter- 
  

   nating 
  with 
  shales 
  in 
  which 
  from 
  15 
  to 
  20 
  feet 
  of 
  rocks 
  are 
  

   exposed. 
  These 
  rocks 
  are 
  also 
  sparingly 
  fossiliferous 
  and 
  the 
  

   following 
  species 
  were 
  obtained:

  There 
  is 
  but 
  a 
  very 
  faint 
  indication 
  of 
  the 
  fine 
  striae 
  and 
  

   possibly 
  there 
  are 
  none.

  Only

  A 
  little 
  farther 
  up 
  the 
  " 
  gulf 
  road 
  " 
  the 
  gorge 
  becomes 
  quite 
  

   narrow 
  at 
  a 
  place 
  known 
  as 
  the 
  " 
  Devil's 
  oven 
  " 
  and 
  here 
  is 
  plenty 
  

   of 
  red 
  shale 
  (B 
  7 
  ) 
  about 
  80 
  feet 
  above 
  the 
  quarry 
  sandstone. 
  The 
  

   altitude 
  of 
  this 
  zone 
  is 
  1750 
  feet 
  A. 
  T.; 
  but 
  the 
  thickness 
  of 
  the 
  

   rocks 
  as 
  given 
  in 
  the 
  above 
  section 
  is 
  too 
  great 
  on 
  account 
  of 
  the 
  

   heavy 
  southerly 
  dip. 
  The 
  fossils 
  found 
  here 
  are 
  a 
  remnant 
  of 
  the 
  

   Ithaca 
  fauna, 
  persisting 
  after 
  the 
  conditions 
  had 
  changed 
  mainly 
  

   to 
  those 
  of 
  the 
  Oneonta 
  formation. 
  It 
  is 
  one 
  of 
  the 
  last 
  localities 
  

   in 
  following 
  the 
  strike 
  of 
  these 
  formations 
  to 
  the 
  eastward 
  where
