  To 
  the 
  southwest 
  of 
  Dutch 
  Settlement 
  (Ruby 
  p. 
  o.) 
  in 
  the 
  

   northern 
  part 
  of 
  Kingston 
  township 
  is 
  a 
  large 
  quarry 
  of 
  flagging 
  

   stone. 
  The 
  color 
  is 
  bluish 
  to 
  bluish 
  gray, 
  some 
  of 
  which 
  is 
  

   faintly 
  banded, 
  forming 
  a 
  ledge 
  five 
  feet 
  thick 
  that 
  is 
  worked. 
  

   Part 
  of 
  the 
  ledge 
  splits 
  into 
  thin 
  even 
  layers 
  from 
  two 
  to 
  three 
  

   inches 
  thick 
  which 
  make 
  excellent 
  flagstone, 
  while 
  the 
  thicker 
  

   layers 
  make 
  building 
  stone. 
  The 
  same 
  layers 
  do 
  not 
  split 
  as 
  

   readily 
  when 
  followed 
  from 
  the 
  flagstone 
  part 
  of 
  the 
  quarry. 
  

   The 
  dip 
  is 
  between 
  4° 
  and 
  5° 
  S, 
  60° 
  W. 
  Above 
  the 
  sandstone 
  are 
  

   argillaceous 
  shales 
  of 
  decidedly 
  greenish 
  color. 
  The 
  sandstone 
  is 
  

   similar 
  to 
  the 
  so-called 
  Hamilton 
  blue 
  flagstone, 
  but 
  it 
  is 
  probably 
  

   in 
  the 
  Sherburne 
  formation. 
  

  

  Farther 
  south 
  in 
  a 
  wild 
  and 
  rugged 
  region 
  is 
  the 
  Sawkill 
  val- 
  

   ley 
  along 
  which 
  are 
  numerous 
  flagstone 
  quarries, 
  specially 
  in 
  the 
  

   vicinity 
  of 
  Jockey 
  hill, 
  in 
  the 
  Hamilton 
  formation, 
  and 
  its 
  top 
  

   crosses 
  the 
  valley 
  about 
  two 
  and 
  one 
  half 
  miles 
  above 
  the 
  vil- 
  

   lage, 
  while 
  the 
  base 
  of 
  the 
  reds 
  is 
  found 
  not 
  far 
  above 
  the 
  Saw- 
  

   kill 
  reservoir 
  more 
  than 
  three 
  miles 
  east 
  of 
  north 
  of 
  West 
  Hurley. 
  

   Kingston, 
  Hurley 
  and 
  Olive 
  townships 
  are 
  crossed 
  by 
  the 
  Ulster 
  

   and 
  Delaware 
  railroad 
  and 
  the 
  section 
  along 
  this 
  railroad 
  was 
  

   described 
  by 
  the 
  writer 
  several 
  years 
  ago, 
  a
