  To 
  the 
  south 
  of 
  Mackey 
  hill 
  along 
  the 
  highway 
  near 
  Whitfield 
  are 
  

   fine 
  blue 
  Hamilton 
  shales 
  belonging 
  in 
  the 
  lower 
  part 
  of 
  the 
  

   formation. 
  

  

  To 
  the 
  east 
  of 
  Tobasco 
  and 
  two 
  and 
  a 
  half 
  miles 
  south 
  of 
  

   Samsonville 
  are 
  the 
  Gray 
  quarries. 
  The 
  dip 
  is 
  5J° 
  N, 
  80° 
  W. 
  

   The 
  rock 
  which 
  alternates 
  with 
  greenish 
  shales 
  is 
  a 
  coarse, 
  bluish 
  

   gray, 
  quite 
  massive 
  sandstone, 
  which 
  does 
  not 
  split 
  into 
  thin 
  

   shales, 
  and 
  which 
  shows 
  crossbedding 
  on 
  the 
  edge 
  of 
  the 
  ledge. 
  

   No 
  fossils 
  were 
  found 
  and 
  the 
  quarries 
  are 
  in 
  the 
  Sherburne 
  

   formation.

  The 
  base 
  of 
  the 
  red 
  rocks 
  on 
  the 
  hill 
  south 
  of 
  Esopus 
  creek 
  

   runs 
  southeasterly 
  for 
  several 
  miles 
  to 
  the 
  hill 
  east 
  of 
  Krum 
  

   corners, 
  when 
  it 
  turns 
  westerly 
  toward 
  Samsonville. 
  This 
  

   carries 
  the 
  Catskill 
  formation 
  somewhat 
  farther 
  east 
  than 
  is 
  

   indicated 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  and 
  the 
  valley 
  to 
  the 
  

   west 
  of 
  Krum 
  hill 
  is 
  in 
  this 
  formation 
  instead 
  of 
  a 
  lower 
  one, 
  for 
  

   on 
  the 
  highway 
  just 
  north 
  of 
  Krum 
  corners 
  or 
  Krumville 
  church 
  

   are 
  red 
  and 
  green 
  mottled, 
  argillaceous 
  shales. 
  On 
  the 
  low 
  hill 
  

   just 
  east 
  of 
  the 
  road 
  and 
  55 
  feet 
  higher 
  is 
  a 
  small 
  quarry 
  of 
  

   coarse 
  grained, 
  bluish 
  gray 
  sandstone 
  which 
  splits 
  into 
  flags. 
  

   There 
  are 
  partings 
  of 
  bluish, 
  argillaceous 
  shales 
  in 
  which 
  are 
  

   fragments 
  of 
  plants. 
  The 
  edges 
  of 
  the 
  outcrop 
  show 
  cross- 
  

   bedding. 
  The 
  dip 
  is 
  6° 
  N, 
  70° 
  W, 
  and 
  on 
  another 
  face 
  of 
  the 
  

   quarry 
  2° 
  N, 
  30° 
  E. 
  Near 
  the 
  corners 
  where 
  the 
  first 
  road 
  north 
  

   of 
  Krum 
  corners 
  turns 
  to 
  the 
  east 
  are 
  red 
  shales 
  which 
  are 
  to 
  

   the 
  southwest 
  of 
  the 
  high 
  hill 
  shown 
  as 
  Catskill 
  on 
  the 
  New 
  York 
  

   map. 
  To 
  the 
  west 
  of 
  Krum 
  corners 
  is 
  the 
  Krumville 
  postoffice 
  

   and 
  one 
  quarter 
  of 
  a 
  mile 
  to 
  the 
  west 
  on 
  the 
  bank 
  of 
  a 
  brook 
  is 
  

   a 
  quarry 
  of 
  bluish 
  sandstone, 
  some 
  of 
  the 
  layers 
  showing 
  a 
  red- 
  

   dish 
  tint. 
  There 
  are 
  plant 
  fragments 
  but 
  no 
  other 
  fossils 
  were 
  

   found. 
  The 
  dip 
  is 
  4° 
  N, 
  70° 
  W, 
  and 
  the 
  quarry 
  is 
  near 
  the 
  top 
  

   of 
  the 
  Sherburne 
  formation 
  for 
  red 
  sandstone 
  apparently 
  in 
  place 
  

   occurs 
  on 
  the 
  highway 
  to 
  the 
  west 
  of 
  the 
  brook 
  near 
  the 
  line 
  

   indicated 
  as 
  the 
  base 
  of 
  the 
  Catskill 
  formation 
  on 
  the 
  state 
  map. 
  

   In 
  Samsonville 
  are 
  conspicuous 
  ledges 
  of 
  coarse 
  grained, 
  greenish 
  

   to 
  greenish 
  gray 
  sandstone 
  which 
  have 
  a
