  argillaceous 
  shales 
  with 
  some 
  sandstones 
  belonging 
  in 
  the 
  

   Oneonta 
  formation. 
  Along 
  the 
  brook 
  and 
  highway 
  from 
  the 
  

   Ouleout 
  valley 
  toward 
  Franklin 
  Station 
  the 
  rocks 
  are 
  partly 
  

   covered 
  for 
  130 
  feet, 
  reds 
  showing 
  now 
  and 
  then, 
  when 
  a 
  con- 
  

   spicuous 
  red 
  sandstone 
  crosses 
  the 
  brook. 
  60 
  feet 
  higher 
  and 
  

   just 
  below 
  the 
  forks 
  in 
  the 
  road 
  is 
  an 
  outcrop 
  of 
  red, 
  shaly 
  sand- 
  

   stone 
  alternating 
  below 
  with 
  greenish 
  layers 
  of 
  sandstone. 
  -This 
  

   locality 
  is 
  about 
  two 
  miles 
  from 
  the 
  tunnel 
  and 
  is, 
  apparently, 
  

   at 
  about 
  the 
  top 
  of 
  the 
  Oneonta 
  formation. 
  Loose 
  along 
  the 
  

   brook 
  and 
  in 
  the 
  fields 
  are 
  numerous 
  blocks 
  of 
  sandstone 
  con- 
  

   taining 
  large 
  numbers 
  of 
  Crinoid 
  segments. 
  Unfortunately 
  the 
  

   northern 
  slope 
  of 
  the 
  hill 
  is 
  generally 
  deeply 
  covered 
  with 
  drift 
  

   and 
  no 
  exposures 
  of 
  these 
  fossiliferous 
  rocks 
  were 
  found. 
  From 
  

   loose 
  blocks 
  in 
  the 
  side 
  of 
  the 
  hill 
  the 
  following 
  species 
  were 
  

   collected: 
  

  

  1 
  Goniophora 
  chemungensis 
  (Van.) 
  Hall

  Tentaculites

  ,

  9 
  Crinoid 
  .segments 
  (aa) 
  

  

  Very 
  abundant 
  in 
  some 
  of 
  the 
  pieces. 
  

  

  They 
  belong, 
  however, 
  in 
  the 
  Chemung 
  formation 
  which 
  was 
  

   estimated 
  by 
  Darton 
  to 
  " 
  have 
  a 
  thickness 
  of 
  about 
  300 
  feet 
  " 
  a 
  to 
  

   the 
  south 
  of 
  Franklin. 
  At 
  590 
  feet 
  above 
  the 
  top 
  of 
  the 
  Oneonta 
  

   red 
  sandstone 
  noted 
  in 
  the 
  brook 
  is 
  a 
  ledge 
  of 
  greenish 
  gray 
  

   sandstone 
  somewhat 
  unevenly 
  bedded 
  (A 
  4 
  ) 
  near 
  the 
  top 
  of 
  the 
  

   hill 
  which 
  is 
  some 
  55 
  feet 
  higher, 
  and 
  on 
  its 
  surface 
  are 
  numerous 
  

   blocks 
  of 
  red 
  sandstone. 
  No 
  red 
  rock 
  was 
  found 
  in 
  place, 
  but 
  

   as 
  this 
  hill 
  barometrically 
  is 
  some 
  190 
  feet 
  above 
  the 
  Merrick- 
  

   ville 
  station 
  it 
  seems 
  probable 
  that
