  In 
  using 
  the 
  name 
  Catskill 
  formation 
  the 
  writer 
  does 
  not 
  wish 
  

   to 
  be 
  regarded 
  as 
  considering 
  the 
  rocks 
  of 
  this 
  formation 
  later 
  

   in 
  age 
  than 
  the 
  Chemung 
  for 
  it 
  is 
  perfectly 
  evident 
  to 
  him 
  that 
  

   at 
  least 
  the 
  lower 
  part 
  of 
  the 
  formation 
  and 
  perhaps 
  all 
  of 
  it 
  is 
  

   synchronous 
  with 
  the 
  Chemung 
  as 
  found 
  farther 
  west 
  in 
  south- 
  

   ern 
  New 
  York. 
  There 
  can 
  be 
  no 
  question 
  but 
  that 
  the 
  Chemung 
  

   merges 
  into 
  the 
  reds 
  and 
  grays 
  of 
  the 
  Catskill 
  as 
  they 
  are 
  fol- 
  

   lowed 
  eastward 
  from 
  the 
  Susquehanna 
  valley. 
  The 
  term 
  Cats- 
  

   kill 
  formation, 
  however, 
  is 
  a 
  convenient 
  name 
  for 
  the 
  great 
  mass 
  

   of 
  red 
  and 
  gray 
  sandstones, 
  shales, 
  and 
  conglomerates 
  found 
  in 
  

   the 
  Catskill 
  mountain 
  region 
  and 
  is 
  used 
  in 
  this 
  sense 
  in 
  the 
  

   present 
  report. 
  

  

  The 
  steep 
  hill 
  to 
  the 
  southeast 
  of 
  Roxbury 
  forming 
  the 
  divide 
  

   between 
  the 
  Batavia 
  kill 
  and 
  the 
  east 
  branch 
  of 
  the 
  Delaware 
  

   was 
  crossed. 
  The 
  section 
  is 
  along 
  the 
  first 
  east 
  road 
  south 
  of 
  Rox- 
  

   .bury 
  which 
  follows 
  a 
  small 
  brook 
  at 
  the 
  northern 
  end 
  of 
  Whortle- 
  

   bury 
  mountain.
