  The 
  base 
  of 
  the 
  Catskill 
  formation 
  crosses 
  the 
  Neversink 
  river 
  

   just 
  below 
  Oakland. 
  On 
  the 
  river 
  bank 
  at 
  the 
  lower 
  Oakland 
  

   bridge 
  from 
  15 
  to 
  20 
  feet 
  of 
  red 
  shale 
  is 
  exposed. 
  At 
  this 
  locality 
  

   a 
  well 
  was 
  drilled 
  between 
  1300 
  and 
  1400 
  feet 
  in 
  depth, 
  and 
  

   according 
  to 
  Mr 
  Case 
  after 
  passing 
  through 
  from 
  18 
  to 
  20 
  feet 
  of 
  

   red 
  shale 
  at 
  the 
  mouth 
  no 
  more 
  was 
  struck, 
  the 
  remainder 
  of 
  the 
  

   well 
  being 
  in 
  " 
  blue 
  stone." 
  This 
  shows 
  conclusively 
  that 
  the 
  red 
  

   shales 
  on 
  the 
  river 
  bank 
  are 
  the 
  lowest 
  reds 
  in 
  this 
  valley. 
  Years 
  

   ago 
  a 
  well 
  was 
  drilled 
  500 
  feet 
  deep 
  in 
  the 
  Bushkill 
  valley, 
  where 
  

   it 
  joins 
  the 
  Never 
  sink 
  at 
  Oakland, 
  the 
  first 
  50 
  feet 
  of 
  which 
  was 
  

   in 
  a 
  clear 
  blue 
  clay. 
  This 
  clay 
  is 
  frequently 
  shown 
  along 
  the 
  

   Bushkill 
  valley. 
  At 
  the 
  upper 
  Oakland 
  bridge 
  on 
  the 
  eastern 
  

   side 
  of 
  the 
  Neversink 
  river 
  is 
  a 
  cliff 
  of 
  greenish 
  gray 
  sandstone 
  

   and 
  green 
  and 
  blue 
  shale 
  perhaps 
  75 
  feet 
  high. 
  No 
  red 
  shale 
  

   occurs 
  in 
  it 
  though 
  the 
  rocks 
  are 
  above 
  the 
  red 
  shales 
  at 
  the 
  

   lower 
  bridge 
  and 
  in 
  the 
  Catskill 
  formation. 
  

  

  In 
  the 
  small 
  quarry 
  at 
  this 
  place 
  the 
  dip 
  varies 
  from 
  J° 
  to 
  1° 
  

   N, 
  20° 
  E, 
  while 
  in 
  the 
  quarry 
  a 
  little 
  farther 
  down 
  the 
  road 
  the 
  

   rocks 
  are 
  nearly 
  horizontal, 
  though 
  the 
  upper 
  part 
  of 
  the 
  ledge 
  

   is 
  so 
  badly 
  shattered 
  that 
  this 
  horizontality 
  may 
  not 
  continue
