  structure. 
  These 
  sandstones 
  are 
  specially 
  conspicuous 
  along 
  the 
  

   Eochester 
  creek 
  near 
  the 
  site 
  of 
  the 
  abandoned 
  tannery 
  and 
  they 
  

   are 
  near 
  the 
  base 
  of 
  the 
  Catskill 
  formation. 
  Along 
  the 
  highway 
  

   on 
  the 
  northern 
  side 
  of 
  the 
  creek 
  one 
  mile 
  below 
  Samsonville 
  are 
  

   outcrops 
  of 
  red 
  and 
  green 
  shales, 
  and 
  above 
  them 
  is 
  a 
  heavy 
  

   ledge 
  of 
  bluish 
  sandstone 
  in 
  which 
  a. 
  small 
  quarry 
  has 
  been 
  

   opened. 
  

  

  The 
  base 
  of 
  the 
  Catskill 
  formation 
  runs 
  southwesterly 
  from 
  

   Samsonville, 
  but 
  it 
  is 
  difficult 
  to 
  follow 
  the 
  line 
  closely 
  on 
  ac* 
  

   count 
  pf 
  the 
  heavy 
  drift 
  and 
  infrequent 
  outcrops. 
  Along 
  Mill 
  

   brook 
  above 
  Mombaccus 
  the 
  country 
  is 
  well 
  covered 
  with 
  drift 
  

   and 
  beds 
  of 
  sand 
  and 
  gravel. 
  An 
  occasional 
  ledge 
  of 
  grayish 
  

   sandstone 
  is 
  shown 
  and 
  near 
  the 
  head 
  of 
  the 
  stream 
  are 
  loose 
  

   pieces 
  of 
  red 
  shale 
  which 
  apparently 
  have 
  not 
  been 
  transported 
  

   far 
  and 
  probably 
  came 
  from 
  near 
  the 
  base 
  of 
  the 
  reds. 
  Below 
  

   Mombaccus 
  the 
  country 
  is 
  also 
  well 
  covered 
  with 
  drift 
  and 
  soil 
  

   so 
  that 
  outcrops 
  of 
  bed 
  rock 
  are 
  infrequent. 
  

  

  On 
  the 
  eastern 
  side 
  of 
  the 
  Vernovy 
  creek 
  a 
  little 
  north 
  of 
  

   Wawarsing 
  are 
  fine 
  Hamilton 
  shales 
  containing 
  some 
  fossils. 
  

   The 
  dip 
  is 
  very 
  heavy 
  being 
  35° 
  slightly 
  west 
  of 
  north. 
  The 
  

   shales 
  near 
  the 
  base 
  of 
  the 
  first 
  small 
  hill 
  are 
  quite 
  fine 
  and 
  

   fossils 
  are 
  common 
  though 
  not 
  abundant. 
  The 
  species 
  however 
  

   are 
  few, 
  Liorliynchus 
  and 
  Ghonetes 
  being 
  the 
  most 
  common.

  Near 
  the

  hill 
  the 
  rocks 
  become 
  coarser 
  and

  occur
