  LXVI 
  A. 
  In 
  the 
  eastern 
  part 
  of 
  Franklin 
  on 
  the 
  southern 
  fork 
  of 
  

   Ouleout 
  brook 
  is 
  the 
  small 
  village 
  of 
  Treadwell 
  (formerly 
  Croton). 
  

   To 
  the 
  south 
  of 
  the 
  village 
  is 
  the 
  valley 
  of 
  Roaring 
  brook 
  and 
  a 
  

   section 
  of 
  350 
  feet 
  was 
  studied 
  leading 
  up 
  this 
  valley 
  and 
  toward 
  

   the 
  summit 
  of 
  the 
  hill 
  on 
  the 
  western 
  side. 
  Directly 
  south 
  of 
  

   Treadwell 
  on 
  the 
  western 
  side 
  of 
  Roaring 
  brook 
  is 
  an 
  exposure 
  

   of 
  some 
  10 
  feet 
  of 
  red 
  sandstone 
  (A 
  2 
  ) 
  perhaps 
  about 
  25 
  feet 
  above 
  

   the 
  center 
  of 
  the 
  village. 
  This 
  outcrop 
  is 
  in 
  the 
  upper 
  part 
  of 
  

   the 
  Oneonta 
  sandstone 
  as 
  is 
  shown 
  on 
  the 
  Geologic 
  map 
  of 
  Netv 
  

   York. 
  For 
  130 
  feet 
  on 
  the 
  side 
  of 
  the 
  hill 
  the 
  rocks 
  are 
  covered, 
  

   then 
  a 
  ledge 
  of 
  thin 
  bedded 
  gray 
  sandstone 
  two 
  feet 
  thick 
  (A 
  4 
  ) 
  

   occurs. 
  The 
  rocks 
  are 
  then 
  mostly 
  covered 
  for 
  88 
  feet 
  when 
  the 
  

   base 
  of 
  the 
  Prime 
  quarry 
  is 
  reached. 
  However, 
  about 
  15 
  feet 
  

   below 
  its 
  base 
  but 
  farther 
  to 
  the 
  east 
  is 
  a 
  ledge 
  of 
  slightly 
  red- 
  

   dish 
  sandstone. 
  Perhaps 
  the 
  reddish 
  color 
  is 
  due 
  to 
  weathering 
  

   and 
  it 
  may 
  be 
  considerably 
  above 
  the 
  top 
  of 
  the 
  Oneonta. 
  The 
  

   rocks 
  are 
  so 
  well 
  covered 
  that 
  on 
  the 
  lower 
  slope 
  of 
  this 
  hill 
  the 
  

   line 
  of 
  division 
  between 
  the 
  Oneonta 
  and 
  Chemung 
  was 
  not 
  de- 
  

   termined. 
  The 
  Prime 
  quarry 
  (A 
  6 
  ) 
  is 
  on 
  the 
  hill 
  about 
  three 
  

   quarters 
  of 
  a 
  mile 
  south 
  of 
  Treadwell 
  and 
  some 
  255 
  feet 
  higher. 
  

   In 
  the 
  wall 
  of 
  the 
  quarry 
  13 
  feet 
  of 
  rocks 
  are 
  shown, 
  the 
  lower 
  

   eight 
  feet 
  being 
  fairly 
  fine 
  grained, 
  greenish 
  gray 
  flagging 
  stone 
  

   which 
  splits 
  into 
  flags 
  from 
  two 
  to 
  three 
  inches 
  in 
  thickness. 
  In 
  

   the 
  debris 
  of 
  the 
  quarry 
  and 
  loose 
  on 
  the 
  hillside 
  are 
  numerous 
  

   blocks 
  of 
  stone 
  containing 
  large 
  numbers 
  of 
  Crinoid 
  segments. 
  

   Such 
  a 
  layer 
  filled 
  with 
  these 
  segments 
  occurs 
  near 
  the 
  top 
  of 
  

   the 
  sandstone. 
  The 
  upper 
  five 
  feet 
  of 
  the 
  quarry 
  is 
  composed 
  

   mainly 
  of 
  greenish 
  argillaceous 
  shales 
  in 
  which 
  are 
  a 
  few 
  coarser 
  

   layers 
  containing 
  numerous 
  Crinoid 
  segments. 
  In 
  addition 
  to 
  

   these 
  a 
  specimen 
  of 
  Tentaciilitcs 
  splenitis 
  Hall 
  (?) 
  and 
  another 
  of 
  

   Orthonota 
  (?) 
  parvula 
  Hall 
  were 
  found. 
  The 
  rocks 
  forming 
  this 
  

   quarry 
  are 
  considered 
  to 
  belong 
  in 
  the 
  lower 
  part 
  of 
  the 
  Che- 
  

   mung. 
  42 
  feet 
  above 
  the 
  top 
  of 
  the 
  quarry 
  is 
  a 
  five-foot 
  ledge
