  Delaware 
  and 
  far 
  into 
  Pennsylvania." 
  a 
  There 
  is 
  no 
  question 
  but 
  

   that 
  the 
  lower 
  reds 
  and 
  grays 
  of 
  Ulster 
  co. 
  and 
  farther 
  south- 
  

   west 
  are 
  synchronous 
  with 
  the 
  rocks 
  of 
  Greene 
  and 
  Albany 
  coun- 
  

   ties 
  which 
  are 
  called 
  Oneonta, 
  but 
  as 
  there 
  is 
  no 
  line 
  of 
  repara- 
  

   tion 
  which 
  can 
  be 
  traced 
  between 
  the 
  lower 
  and 
  middle 
  rocks 
  of 
  

   this 
  mass 
  it 
  seems 
  as 
  well 
  to 
  the 
  author 
  to 
  class 
  them 
  together 
  

   as 
  one 
  formation, 
  to 
  which 
  would 
  be 
  applied 
  the 
  name 
  Oatskill 
  

   in 
  the 
  sense 
  in 
  which 
  it 
  was 
  used 
  by 
  Mather 
  for 
  this 
  region. 
  In 
  

   fact 
  I 
  am 
  inclined 
  to 
  think 
  that 
  the 
  above 
  arrangement 
  would 
  be 
  

   a 
  better 
  classification 
  for 
  this 
  mass 
  of 
  rocks 
  in 
  Greene, 
  Albany 
  

   and 
  southeastern 
  Schoharie 
  county 
  than 
  the 
  plan 
  of 
  representa- 
  

   tion 
  followed 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York. 
  The 
  above 
  Usage 
  

   apparently 
  agrees 
  with 
  that 
  suggested 
  by 
  Prof. 
  H. 
  S. 
  Williams 
  

   for 
  the 
  term 
  Catskill 
  in 
  eastern 
  New 
  York 
  for 
  he 
  said, 
  " 
  It 
  is 
  an 
  

   appropriate 
  local 
  formation 
  name 
  for 
  deposits 
  succeeding 
  Hamil- 
  

   ton 
  or 
  Chemung 
  formations 
  in 
  eastern 
  New 
  York 
  and 
  farther 
  

   southwest. 
  . 
  . 
  The 
  Catskill 
  is 
  a 
  distinct 
  and 
  well 
  defined 
  geologi- 
  

   cal 
  formation, 
  but 
  it 
  is 
  not 
  a 
  period 
  or 
  an 
  epoch, 
  nor 
  does 
  it 
  repre- 
  

   sent 
  any 
  particular 
  period 
  of 
  geological 
  time." 
  & 
  

  

  Under 
  the 
  eastern 
  townships 
  of 
  Greene 
  co. 
  the 
  upper 
  Ham- 
  

   ilton, 
  Sherburne, 
  and 
  lower 
  reds 
  were 
  traced 
  from 
  Catskill 
  town- 
  

   ship 
  across 
  the 
  county 
  line 
  into 
  Saugerties 
  township, 
  consequent- 
  

   ly 
  at 
  this 
  locality 
  we 
  will 
  begin 
  the 
  consideration 
  of 
  the 
  limits 
  

   of 
  these 
  formations 
  toward 
  the 
  southwest. 
  The 
  banded 
  sand- 
  

   stone 
  found 
  in 
  the 
  small 
  quarry 
  to 
  the 
  west 
  of 
  High 
  falls 
  on 
  the 
  

   Kaaterskill 
  may 
  be 
  followed 
  along 
  the 
  highway 
  to 
  the 
  esw 
  to 
  

   the 
  three 
  corners 
  one 
  half 
  mile 
  northwest 
  of 
  Quarryville. 
  There 
  

   is 
  a 
  quarry 
  to 
  the 
  west 
  of 
  the 
  turn 
  and 
  another 
  to 
  the 
  east, 
  both 
  

   of 
  which 
  contain 
  the 
  banded 
  hard 
  sandstones. 
  In 
  the 
  western 
  

   one 
  there 
  are 
  coarse, 
  greenish 
  shales 
  below 
  the 
  sandstones, 
  while 
  

   some 
  of 
  the 
  sandstones 
  in 
  the 
  more 
  eastern 
  quarry 
  have 
  a 
  slightly 
  

   reddish 
  tint. 
  No 
  fossils 
  were 
  found 
  and 
  the 
  rocks 
  are 
  apparently 
  

   in 
  the 
  Sherburne 
  formation. 
  The 
  large 
  quarries 
  in 
  Quarryville 
  

   contain 
  coarse, 
  thick 
  bedded, 
  bluish 
  gray 
  sandstones 
  with 
  shale
