  Kaaterskill 
  creek 
  above 
  the 
  bridge 
  opposite 
  the 
  hotel 
  in 
  the 
  

   upper 
  end 
  of 
  the 
  village, 
  with 
  the 
  red 
  shaly 
  rock 
  (no. 
  12) 
  at 
  the 
  

   top 
  of 
  the 
  Manorkill 
  cataracts 
  near 
  Strykersville. 
  The 
  author 
  

   did 
  not 
  see 
  any 
  evidence 
  to 
  support 
  this 
  exact 
  correlation 
  of 
  these 
  

   two 
  sections, 
  nor 
  did 
  Sherwood 
  give 
  any 
  reason 
  for 
  his 
  correla- 
  

   tion. 
  But 
  few 
  fossils 
  have 
  been 
  found 
  in 
  the 
  rocks, 
  the 
  animal 
  

   remains 
  in 
  which 
  are 
  bones 
  and 
  plates 
  of 
  fish 
  that 
  were 
  first 
  dis- 
  

   covered 
  by 
  Sherwood, 
  and 
  on 
  account 
  of 
  their 
  presence 
  in 
  con- 
  

   siderable 
  abundance 
  in 
  three 
  layers 
  (ncs. 
  105, 
  107 
  and 
  111) 
  in 
  the 
  

   lower 
  part 
  of 
  the 
  clove 
  he 
  termed 
  them 
  " 
  fish-bone 
  beds." 
  The 
  

   lower 
  bed 
  is 
  in 
  a 
  greenish, 
  shaly 
  rock 
  which 
  is 
  quite 
  hard, 
  and 
  

   there 
  are 
  numerous 
  fragments 
  of 
  fish 
  bones 
  and 
  plates 
  most 
  of 
  

   which 
  are 
  badly 
  broken. 
  The 
  second 
  ^bed 
  is 
  in 
  a 
  mottled 
  red 
  and 
  

   green 
  argillaceous 
  and 
  rather 
  soft 
  shale. 
  The 
  bed 
  of 
  no. 
  Ill 
  is 
  

   near 
  the 
  bottom 
  of 
  a 
  mass 
  of 
  red 
  shale, 
  103 
  feet 
  in 
  thickness 
  ac- 
  

   cording 
  to 
  Sherwood, 
  where 
  fragments 
  of 
  fish 
  scales 
  were 
  seen, 
  

   but 
  they 
  are 
  not 
  nearly 
  so 
  abundant 
  as 
  in 
  the 
  two 
  lower 
  beds. 
  

   These 
  specimens 
  were 
  not 
  identified, 
  so 
  far 
  as 
  known 
  to 
  the 
  

   writer, 
  except 
  that 
  Prof. 
  Hall 
  referred 
  to 
  these 
  beds, 
  stating 
  that 
  

   they 
  were 
  " 
  charged 
  with 
  the 
  remains 
  of 
  Holoptychius" 
  a 
  Ad- 
  

   ditional 
  specimens 
  were 
  collected 
  by 
  the 
  writer 
  which 
  have 
  been 
  

   studied 
  by 
  C. 
  K. 
  Eastman, 
  who 
  identified 
  Dinichthys 
  sp. 
  and 
  

   Sauripteris 
  Taylori 
  Hall. 
  (See 
  Dr 
  Eastman's 
  description 
  of 
  these 
  

   specimens 
  at 
  the 
  close 
  of 
  this 
  report.) 
  

  

  In 
  addition 
  to* 
  the 
  fish 
  remains 
  the 
  author 
  found 
  numerous 
  

   specimens 
  of 
  Psilophyton 
  princeps 
  Dn. 
  in 
  a 
  bluish 
  gray 
  arenaceous 
  

   layer 
  at 
  the 
  foot 
  of 
  the 
  Cascades 
  below 
  Haines's 
  falls, 
  about 
  400 
  

   feet 
  below 
  the 
  base 
  of 
  the 
  heavy 
  conglomerate 
  which 
  is 
  well 
  

   exposed 
  in 
  Twilight 
  park 
  on 
  the 
  southern 
  side 
  of 
  the 
  clove.

  The 
  massive 
  conglomerate 
  ledge 
  in 
  Twilight 
  park 
  occurs 
  at 
  an 
  

   elevation 
  of 
  about 
  2000 
  feet 
  A. 
  T. 
  About 
  15 
  feet 
  containing 
  

   large 
  white 
  and 
  pinkish 
  quartz 
  pebbles 
  are 
  shown 
  on 
  the 
  drive- 
  

   way. 
  Several 
  conglomerates 
  are 
  mentioned 
  near 
  this 
  part 
  of 
  

   Sherwood's 
  section 
  and 
  I 
  am 
  uncertain 
  which
