  steepness 
  of 
  this 
  dip 
  gradually 
  decreases 
  westward 
  and 
  gives 
  

   place 
  to 
  a 
  very 
  gentle 
  inclination 
  to 
  the 
  westward. 
  It 
  also 
  

   decreases 
  to 
  the 
  eastward 
  on 
  the 
  summit 
  of 
  Shawangunk 
  mount- 
  

   ain. 
  The 
  southern 
  and 
  eastern 
  side 
  of 
  this 
  valley 
  is 
  the 
  long 
  

   western 
  slope 
  of 
  the 
  Shawangunk 
  mountain 
  with 
  its 
  bare 
  flanks 
  

   of 
  Shawangunk 
  grit. 
  To 
  the 
  westward 
  are 
  long 
  spurs 
  of 
  the 
  

   foothills 
  of 
  the 
  Catskills. 
  

  

  A 
  mile 
  west 
  of 
  High 
  Falls, 
  just 
  west 
  of 
  the 
  turnpike 
  to 
  Ellen- 
  

   ville, 
  there 
  are 
  exhibited 
  in 
  hill 
  slopes 
  the 
  lower 
  Shaly, 
  Becraft 
  

   and 
  upper 
  Shaly 
  limestones 
  and 
  a 
  short 
  distance 
  south 
  the 
  lower 
  

   Shaly 
  beds 
  are 
  seen 
  along 
  the 
  turnpike. 
  Along 
  the 
  ridge 
  west- 
  

   ward 
  on 
  the 
  road 
  to 
  Kripple 
  Bush, 
  the 
  Becraft 
  and 
  upper 
  Shaly 
  

   limestones 
  are 
  seen, 
  capped 
  by 
  the 
  Oriskany 
  which 
  extends 
  over 
  

   an 
  area 
  of 
  considerable 
  width 
  sloping 
  to 
  the 
  westward. 
  This 
  

   area 
  is 
  succeeded 
  by 
  a 
  sharp 
  rise 
  due 
  to 
  a 
  wide 
  ridge 
  of 
  Esopus 
  

   shales, 
  which 
  is 
  a 
  marked 
  feature 
  from 
  Stone 
  Ridge 
  for 
  twelve 
  

   miles 
  southward. 
  The 
  Esopus 
  formation 
  here 
  consists 
  of 
  very 
  

   hard 
  dark 
  slates 
  which 
  merge 
  into 
  an 
  upper 
  member 
  of 
  dark 
  slaty 
  

   sandstones. 
  On 
  the 
  western 
  slope 
  of 
  this 
  ridge, 
  as 
  in 
  the 
  region 
  

   northward, 
  the 
  Onondaga 
  limestones 
  extend 
  to 
  a 
  valley 
  of 
  

   considerable 
  width, 
  in 
  greater 
  part 
  heavily 
  covered 
  with 
  drift. 
  

   The 
  relations 
  of 
  these 
  features 
  in 
  the 
  exposures 
  extending 
  from 
  

   Kripple 
  Bush 
  eastward 
  are 
  shown 
  in 
  the 
  following 
  figure

  The 
  Clinton 
  and 
  Medina 
  bhales 
  are 
  rarely 
  exposed 
  in 
  this 
  

   valley, 
  and 
  the 
  description 
  of 
  their 
  occurrence 
  at 
  High 
  Falls 
  will 
  

   answer 
  for 
  the 
  entire 
  region 
  so 
  far 
  as 
  I 
  have 
  seen 
  them.

  the

  apparently 
  runs

  lying 
  in

   excavated 
  along
