  nated 
  lenses. 
  It 
  contains 
  Pentamerus 
  galeatus 
  and 
  crinoidal 
  

   fragments. 
  Its 
  thickness 
  was 
  not 
  determined, 
  but 
  it 
  is 
  fully 
  

   thirty 
  feet 
  as 
  stated 
  by 
  Davis. 
  The 
  lower 
  Shaly 
  limestone 
  

   extends 
  along 
  the 
  center 
  of 
  the 
  ridge 
  with 
  a 
  thickness 
  of 
  about 
  

   sixty 
  feet, 
  and 
  the 
  Becraft 
  limestone 
  lies 
  high 
  up 
  on 
  the 
  western 
  

   slope. 
  Both 
  dip 
  steeply 
  to 
  the 
  west. 
  There 
  are 
  lime 
  quarries 
  in 
  

   the 
  Becraft 
  beds 
  which 
  expose 
  a 
  thickness 
  of 
  about 
  thirty 
  -five 
  

   feet 
  of 
  the 
  usual 
  heavily-bedded, 
  light-colored, 
  highly 
  fossiliferous 
  

   limestone, 
  containg 
  abundant 
  calcite 
  replacements 
  of 
  crinoid 
  cups. 
  

   One 
  of 
  these 
  quarries, 
  lying 
  north 
  of 
  the 
  road 
  from 
  Kingston 
  to 
  

   Kingston 
  Point, 
  is 
  shown 
  in 
  plate 
  5. 
  The 
  upper 
  Shaly 
  lime- 
  

   stones 
  extend 
  down 
  the 
  western 
  slope 
  of 
  the 
  ridge. 
  The 
  full 
  

   thickness 
  of 
  the 
  formation 
  is 
  well 
  exposed 
  near 
  the 
  end 
  of 
  the 
  

   northern 
  loop 
  of 
  the 
  railroad, 
  where 
  the 
  ridge 
  widens 
  somewhat, 
  

   and 
  here 
  also 
  there 
  are 
  excellent 
  outcrops 
  of 
  Oriskany 
  beds, 
  

   which 
  are 
  more 
  widely 
  eroded 
  southward. 
  The 
  upper 
  Shaly 
  

   beds 
  have 
  a 
  thickness 
  of 
  about 
  125 
  feet. 
  They 
  are 
  similar 
  to 
  the 
  

   lower 
  Shaly 
  beds, 
  and 
  consist 
  of 
  brownish-gray 
  impure 
  lime- 
  

   stones 
  traversed 
  by 
  slaty 
  cleavage. 
  They 
  are, 
  as 
  usual, 
  sparingly 
  

   fossiliferous, 
  containing 
  Zejttcena 
  rhomboidalis, 
  Strqpheodonta 
  

   radiate/., 
  Spirifer 
  ?nacroj?leura, 
  Spirifer 
  jperlamellosus, 
  Orthis 
  

   oblata, 
  and 
  others. 
  The 
  Oriskany 
  formation 
  is 
  here 
  extensively 
  

   developed, 
  and 
  it 
  contains 
  a 
  bed 
  of 
  conglomerate 
  which, 
  as 
  stated 
  

   by 
  Davis, 
  extends 
  over 
  a 
  considerable 
  area 
  about 
  Eondout. 
  This 
  

   bed 
  consists 
  of 
  small 
  pebbles, 
  up 
  to 
  a 
  quarter 
  or 
  a 
  third 
  of 
  an 
  

   inch 
  in 
  diameter, 
  in 
  a 
  slightly 
  calcareous 
  sandy 
  matrix. 
  The 
  

   pebbles 
  vary 
  from 
  rounded 
  to 
  subangular 
  and 
  consist 
  mainly 
  of 
  

   white 
  quartz. 
  It 
  attains 
  a 
  thickness 
  of 
  nine 
  feet 
  at 
  several 
  points 
  

   but 
  is 
  not 
  continuous 
  throughout. 
  Its 
  greatest 
  development 
  is 
  just 
  

   north 
  of 
  Wilbur 
  in 
  a 
  steep 
  hill 
  slope 
  near 
  the 
  bank 
  of 
  Bondout 
  

   creek, 
  but 
  it 
  is 
  well 
  characterized 
  in 
  the 
  outcrop 
  near 
  the 
  northern 
  

   end 
  of 
  loop 
  of 
  the 
  Ulster 
  and 
  Delaware 
  railway. 
  The 
  upper 
  beds 
  

   of 
  the 
  formation 
  are 
  dark, 
  hard, 
  calcareous 
  sandstones, 
  with 
  some 
  

   cherty 
  bands, 
  which 
  weather 
  to 
  a 
  dull 
  snuff-brown 
  and 
  exhibit 
  

   abundant 
  casts 
  of 
  many 
  typical 
  Oriskany 
  fossils. 
  The 
  total 
  

   thickness 
  of 
  the 
  members 
  in 
  this 
  locality 
  is 
  about 
  thirty 
  feet, 
  

   which 
  is 
  a 
  most 
  unusual 
  thickness 
  for 
  the 
  formation. 
  To 
  the 
  

   west 
  of 
  the 
  Oriskany 
  belt 
  there 
  are 
  high 
  ridges 
  of 
  Esopus 
  shales 
  — 
  

   Cauda 
  galli 
  grit.
