  formation 
  had 
  been 
  traced 
  into 
  eastern 
  New 
  York 
  so 
  that 
  there 
  

   is 
  no 
  mention 
  of 
  that 
  formation 
  though 
  it 
  was 
  stated 
  in 
  reference 
  

   to 
  the 
  " 
  Hudson 
  river 
  bluestone 
  " 
  quarries 
  that 
  " 
  stratigraphi- 
  

   cally 
  the 
  lower 
  portion 
  of 
  these 
  quarries 
  belongs 
  in 
  the 
  Hamilton 
  

   and 
  the 
  upper 
  part 
  of 
  the 
  belt 
  in 
  the 
  Portage."^ 
  In 
  the 
  long 
  rail- 
  

   road 
  cut 
  one 
  half 
  a 
  mile 
  east 
  of 
  West 
  Hurley 
  are 
  thick 
  and 
  thin 
  

   bedded 
  sandstones 
  alternating 
  with 
  bluish, 
  fine 
  argillaceous 
  and 
  

   greenish 
  blocky 
  shales. 
  In 
  places 
  the 
  cut 
  is 
  from 
  25 
  to 
  30 
  feet 
  in 
  

   depth 
  and 
  the 
  rocks 
  are 
  shown 
  on 
  the 
  highway 
  below 
  the 
  rail- 
  

   road. 
  The 
  dip 
  in 
  places 
  varies 
  from 
  2J° 
  to 
  3J° 
  S, 
  45° 
  W. 
  Frag- 
  

   ments 
  of 
  plants 
  were 
  the 
  only 
  fossils 
  found 
  and 
  the 
  cut 
  seems 
  to 
  

   be 
  in 
  the 
  Sherburne 
  formation. 
  On 
  the 
  highway 
  just 
  below 
  the 
  

   Bristol 
  hill 
  church 
  and 
  only 
  a 
  short 
  distance 
  west 
  of 
  Stony 
  Hol- 
  

   low 
  are 
  blue, 
  arenaceous, 
  blocky 
  shales 
  which 
  contain 
  a 
  few 
  

   Hamilton 
  fossils. 
  At 
  the 
  eastern 
  end 
  of 
  the 
  first 
  railroad 
  cut 
  

   west 
  of 
  Bristol 
  church, 
  are 
  fine 
  blue 
  shales, 
  in 
  which 
  Hamilton 
  

   fossils 
  are 
  abundant. 
  The 
  rocks 
  at 
  Bristol 
  church 
  are 
  clearly 
  in 
  

   the 
  Hamilton 
  formation 
  and 
  the 
  following 
  fauna 
  was 
  obtained
