  Hurley 
  township, 
  crossing 
  Esopus 
  creek 
  below 
  the 
  Hudson 
  river 
  

   pulp 
  mill, 
  and 
  then 
  runs 
  across 
  the 
  western 
  part 
  of 
  Marbletown 
  

   into 
  Rochester. 
  On 
  the 
  hill 
  south 
  of 
  the 
  Esopus 
  creek 
  about 
  two 
  

   and 
  one 
  half 
  miles 
  west 
  of 
  Marbletown 
  are 
  bluish, 
  concretionary 
  

   sandstones 
  which 
  are 
  not 
  far 
  below 
  the 
  blue 
  sandstone 
  quarries 
  

   at 
  the 
  three 
  corners 
  where 
  one 
  road 
  turns 
  to 
  the 
  south. 
  The 
  

   upper 
  part 
  of 
  the 
  sandstone 
  ledge 
  is 
  heavy 
  and 
  crossbedded, 
  

   below 
  which 
  are 
  quite 
  extensive 
  flagstone 
  quarries 
  in 
  bluish 
  gray, 
  

   sandstone 
  which 
  alternates 
  with 
  bluish 
  and 
  greenish 
  argillaceous 
  

   shales. 
  The 
  dip 
  is 
  from 
  3-|° 
  to 
  4°N, 
  50°E 
  and 
  the 
  quarries 
  are 
  

   in 
  the 
  Sherburne 
  formation. 
  Not 
  far 
  below 
  the 
  quarries 
  are 
  

   coarse, 
  arenaceous, 
  blue 
  Hamilton 
  shales 
  in 
  which 
  are 
  some 
  fos- 
  

   sils, 
  as 
  Chonetes 
  coronata 
  (Con.) 
  Hall 
  and 
  fragments 
  of 
  a 
  few 
  other 
  

   species. 
  These 
  shales 
  are 
  near 
  the 
  top 
  of 
  the 
  Hamilton 
  and 
  some 
  

   225 
  feet 
  below 
  the 
  base 
  of 
  the 
  lowest 
  reds 
  on 
  the 
  hill 
  above. 
  This 
  

   section 
  gives 
  the 
  approximate 
  thickness 
  of 
  the 
  Sherburne 
  forma- 
  

   tion 
  at 
  this 
  locality. 
  

  

  At 
  the 
  northern 
  end 
  of 
  the 
  Lynesville 
  pond 
  about 
  one 
  and 
  a 
  

   half 
  miles 
  nw 
  of 
  Kripplebush 
  is 
  a 
  small 
  quarry 
  in 
  bluish 
  Hamil- 
  

   ton 
  sandstone 
  alternating 
  with 
  bluish 
  shale, 
  in 
  which 
  are 
  Ham- 
  

   ilton 
  fossils, 
  Camarotoechia 
  congregata 
  (Con.) 
  H. 
  & 
  C. 
  and 
  Ten- 
  

   taculites 
  spiculus 
  Hall. 
  Some 
  of 
  the 
  rock 
  contains 
  quartz 
  peb- 
  

   bles. 
  To 
  the 
  west 
  of 
  Lynesville 
  is 
  the 
  steep 
  Mackey 
  hill 
  which 
  

   is 
  some 
  two 
  miles 
  northwest 
  of 
  Kripplebush. 
  On 
  top 
  of 
  the 
  hill 
  

   are 
  the 
  Mackey 
  flagging 
  stone 
  quarries, 
  some 
  of 
  the 
  stone 
  being 
  

   bluish 
  gray 
  in 
  color 
  and 
  some 
  banded 
  grayish. 
  The 
  sandstone 
  

   is 
  in 
  rather 
  coarse 
  layers 
  and 
  does 
  not 
  split 
  into 
  thin 
  flags. 
  It 
  

   is 
  capped 
  by 
  a 
  considerable 
  thickness 
  of 
  bluish 
  argillaceous 
  shale 
  

   in 
  which 
  no 
  fossils 
  were 
  found. 
  There 
  is 
  a 
  stratum 
  of 
  conglom- 
  

   erate 
  six 
  inches 
  thick 
  in 
  which 
  are 
  red, 
  black 
  and 
  various 
  colored 
  

   pebbles. 
  The 
  dip 
  is 
  between 
  4° 
  and 
  5° 
  N, 
  30° 
  E. 
  In 
  the 
  some- 
  

   what 
  shaly 
  partings 
  are 
  fossils, 
  as 
  Spvrifer 
  mucronatus 
  (Con.) 
  

   Bill., 
  Chonetes 
  coronata 
  (Con.) 
  Hall; 
  Camarotoechia 
  congregata 
  

   (Con.) 
  H. 
  & 
  C; 
  Tropidoleptus 
  carinatus 
  Hall; 
  Chonetes 
  setigera 
  

   Hall; 
  Prothyris 
  lanceolata 
  Hall 
  and 
  Crinoid 
  stem, 
  and 
  the 
  rocks 
  

   are 
  apparently 
  in 
  the 
  Hamilton 
  formation 
  though 
  near 
  its 
  top.
