  In 
  another 
  

   place 
  he 
  states 
  that 
  " 
  This 
  part 
  of 
  the 
  series 
  can 
  be 
  examined 
  

   satisfactorily 
  only 
  by 
  following 
  up 
  the 
  bed 
  of 
  a 
  stream 
  near 
  which 
  

   the 
  turnpike 
  passes. 
  These 
  strata 
  are 
  probably 
  1000 
  feet 
  in 
  

   thickness."

  On 
  the 
  roads 
  to 
  the 
  west 
  of 
  Kiskatom 
  are 
  numerous 
  outcrops 
  

   of 
  red 
  shales 
  and 
  some 
  sandstones. 
  On 
  the 
  road 
  to 
  the 
  south 
  

   leading 
  down 
  into 
  the 
  Kaaterskill 
  valley 
  are 
  massive, 
  hard 
  sand- 
  

   stones 
  with 
  banded 
  structure 
  which 
  are 
  in 
  the 
  Sherburne 
  forma- 
  

   tion. 
  In 
  a 
  small 
  quarry 
  some 
  35 
  feet 
  lower 
  are 
  massive 
  sand- 
  

   stones 
  which 
  split 
  into 
  thick 
  layers. 
  Plenty 
  of 
  plant 
  stems 
  were 
  

   found 
  in 
  these 
  rocks 
  but 
  no 
  other 
  fossils. 
  The 
  dip 
  is 
  8° 
  N 
  60° 
  W. 
  

   At 
  the 
  three 
  corners 
  of 
  the 
  road 
  a 
  little 
  lower 
  than 
  the 
  quarry 
  

   are 
  blue 
  shales 
  containing 
  Hamilton 
  fossils, 
  consequently 
  it 
  ap- 
  

   pears 
  that 
  the 
  sandstones 
  in 
  the 
  quarry 
  are 
  near 
  the 
  dividing 
  

   line 
  between 
  the 
  Hamilton 
  and 
  Sherburne 
  formations.

  A

  At 
  the 
  High 
  falls 
  on 
  the 
  Kaaterskill 
  creek 
  not 
  far 
  

   from 
  the 
  Greene 
  and 
  Ulster 
  county 
  line 
  is 
  a 
  deep 
  and 
  rocky 
  gorge 
  

   in 
  which 
  the 
  upper 
  Hamilton 
  rocks 
  are 
  finely 
  shown. 
  Below 
  the 
  

   massive 
  sandstone 
  stratum 
  which 
  forms 
  the 
  bed 
  of 
  the 
  creek 
  

   above 
  the 
  falls 
  are 
  rather 
  fine, 
  blue 
  argillaceous 
  shales 
  (A 
  1 
  ) 
  which 
  

   contain 
  a 
  fair 
  Hamilton' 
  fauna 
  of 
  the 
  species 
  usually 
  found 
  in 
  the 
  

   fine 
  shales 
  of 
  that 
  formation. 
  The 
  following 
  species 
  were
