  part 
  of 
  the 
  mountain 
  there 
  are 
  ledges 
  of 
  greenish 
  gray 
  and 
  bluish 
  

   sandstones 
  alternating 
  with 
  red 
  sandstones 
  and 
  shales, 
  while 
  the 
  

   red 
  rocks 
  predominate 
  in 
  the 
  upper 
  450 
  feet. 
  No 
  fossils 
  were 
  

   found 
  in 
  any 
  of 
  the 
  outcrops 
  and 
  they 
  certainly 
  agree 
  in 
  litho- 
  

   logic 
  characters 
  and 
  stratigraphic 
  position 
  with 
  the 
  rocks 
  of 
  the 
  

   Catskill 
  formation. 
  

  

  Eastern 
  townships 
  

  

  The 
  eastern 
  townships 
  of 
  Greene 
  co. 
  from 
  the 
  north 
  to 
  the 
  

   south 
  are 
  New 
  Baltimore, 
  Coxsackie, 
  Athens 
  and 
  Catskill, 
  while 
  

   Cairo 
  lies 
  to 
  the 
  south 
  of 
  the 
  western 
  part 
  of 
  Coxsackie 
  and 
  west 
  

   of 
  Athens. 
  The 
  lines 
  separating 
  the 
  Ilamilton 
  and 
  Sherburne 
  

   and 
  the 
  Sherburne 
  and 
  Oneonta 
  formations 
  have 
  already 
  been 
  

   described 
  across 
  New 
  Baltimore 
  township 
  and 
  they 
  will 
  now 
  be 
  

   traced 
  to 
  the 
  south 
  across 
  the 
  county. 
  

  

  Along 
  the 
  Cabin 
  river 
  from 
  Grapeville 
  in 
  the 
  western 
  part 
  of 
  

   New 
  Baltimore 
  township 
  to 
  Urlton 
  in 
  the 
  western 
  central 
  part 
  of 
  

   Coxsackie 
  township, 
  there 
  are 
  numerous 
  small, 
  rounded 
  hills 
  

   composed 
  largely 
  of 
  soil, 
  gravel 
  and 
  boulders, 
  between 
  which 
  are 
  

   marshy 
  and 
  swampy 
  flats. 
  The 
  rocks 
  are 
  mostly 
  covered 
  by 
  

   these 
  drift 
  deposits 
  so 
  that 
  it 
  is 
  a 
  difficult 
  region 
  in 
  which 
  to 
  trace 
  

   the 
  boundaries 
  of 
  geological 
  formations.

  of 
  a 
  small 
  brook 
  one 
  fourth

   east 
  of 
  Urlton 
  are 
  blue 
  fossiliferous 
  shales 
  in 
  which 
  typical 
  Hamil-

  fossils 
  are 
  abundant.
