  65 
  to 
  70 
  feet 
  of 
  these 
  grayish 
  sandstones 
  there 
  is 
  a 
  stratum 
  of 
  

   reddish 
  sandstone 
  which 
  is 
  followed 
  by 
  from 
  80 
  to 
  85 
  feet 
  of 
  

   mostly 
  greenish 
  gray, 
  coarse 
  grained 
  sandstone 
  (B 
  4 
  ) 
  the 
  layers 
  

   of 
  which 
  are 
  rather 
  more 
  massive 
  than 
  those 
  of 
  B 
  3 
  . 
  Interstra- 
  

   tified 
  with 
  these 
  greenish 
  sandstones 
  are 
  layers 
  of 
  reddish 
  sand- 
  

   storm 
  and 
  shale 
  a 
  few 
  feet 
  in 
  thickness. 
  Near 
  the 
  top 
  of 
  B 
  4 
  is 
  

   a 
  sn 
  \11 
  flagging 
  stone 
  quarry, 
  the 
  flags 
  of 
  which 
  are 
  from 
  one 
  to 
  

   two 
  . 
  aches 
  thick, 
  coarse 
  grained 
  and 
  decidedly 
  greenish 
  gray 
  in 
  

   color. 
  In 
  places 
  the 
  layers 
  are 
  very 
  much 
  crossbedded. 
  The 
  dip 
  

   noted 
  is 
  from 
  4° 
  to 
  4°+ 
  S, 
  30° 
  W 
  and 
  2° 
  N, 
  60° 
  W. 
  At 
  B 
  5 
  are 
  

   lieavy 
  ledges 
  of 
  coarse, 
  greenish 
  gray 
  sandstone, 
  very 
  coarse 
  

   grained 
  near 
  the 
  middle 
  of 
  the 
  ledge, 
  with 
  large 
  quartz 
  pebbles 
  

   and 
  at 
  the 
  top 
  is 
  red 
  sandstone. 
  On 
  the 
  old 
  road 
  near 
  Jewett 
  

   hights, 
  which 
  are 
  1810 
  feet 
  A. 
  T., 
  are 
  glacial 
  striae 
  running 
  

   north 
  and 
  south. 
  On 
  the 
  hill 
  to 
  the 
  northeast 
  of 
  Jewett 
  hights 
  the 
  

   rocks 
  are 
  mainly 
  red 
  sandstones 
  and 
  shales, 
  and 
  this 
  region 
  was 
  

   represented 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  as 
  near 
  the 
  base 
  of 
  

   the 
  Catskill 
  formation 
  as 
  well 
  as 
  Jewett 
  hights 
  and 
  the 
  hill 
  to 
  

   the 
  northwest. 
  

  

  LXI 
  C. 
  Another 
  section 
  about 
  four 
  miles 
  east 
  of 
  LXI 
  B 
  was 
  

   examined 
  across 
  the 
  belt 
  of 
  country 
  mapped 
  as 
  Chemung 
  from 
  

   Hensonville 
  to 
  Windham 
  in 
  the 
  upper 
  part 
  of 
  the 
  Bataviakill 
  

   valley. 
  This 
  section 
  is 
  here 
  reproduced 
  and 
  as 
  will 
  be 
  readily 
  

   seen 
  the 
  rocks 
  are 
  not 
  nearly 
  as 
  well 
  shown 
  as 
  on 
  the 
  section 
  

   south 
  of 
  Ashland. 
  The 
  lower 
  part 
  of 
  the 
  section 
  is 
  on 
  the 
  lower 
  

   part 
  of 
  the 
  hill 
  to 
  the 
  south 
  of 
  Windham 
  and 
  the 
  Bataviakill 
  

   which 
  is 
  represented 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  as 
  in 
  the 
  

   lower 
  part 
  of 
  the 
  Chemung. 
  It 
  will 
  be 
  noticed 
  that 
  the 
  rocks 
  

   consist 
  of 
  bluish 
  gray 
  and 
  greenish 
  gray, 
  coarse 
  grained 
  sand- 
  

   stones 
  alternating 
  with 
  red 
  sandstones 
  and 
  shales. 
  The 
  base 
  

   of 
  these 
  rocks 
  is 
  somewhat 
  above 
  the 
  highway 
  and 
  they 
  have 
  a 
  

   thickness 
  of 
  125 
  feet. 
  Then 
  for 
  95 
  feet 
  the 
  rocks 
  are 
  covered, 
  

   succeeding 
  which 
  for 
  70 
  feet 
  the 
  slope 
  is 
  partly 
  covered 
  but 
  has 
  

   frequent 
  outcrops 
  of 
  red 
  shales 
  and 
  thin 
  sandstones. 
  No 
  fossils 
  

   were 
  found 
  on 
  this 
  hillside. 
  On 
  top 
  of 
  the 
  hill 
  southwest 
  of 
  

   Hensonville 
  is 
  a 
  small 
  flagstone 
  quarry 
  in 
  coarse 
  grained, 
  green-
