  compared 
  the 
  Chemung 
  section 
  south 
  of 
  Franklin 
  with 
  

   that 
  at 
  Treadwell 
  (Croton) 
  stating 
  that 
  in 
  tracing 
  the 
  fossilifer- 
  

   ous 
  shales 
  of 
  the 
  Chemung 
  eastward 
  from 
  Franklin 
  " 
  they 
  were 
  

   found 
  to 
  gradually 
  merge 
  into 
  flags 
  and 
  then 
  into 
  harder, 
  "'coarse 
  

   sandstones 
  till 
  at 
  Croton, 
  10 
  miles 
  east, 
  their 
  horizon 
  is 
  repre- 
  

   sented 
  by 
  a 
  heavy 
  mass 
  of 
  coarse, 
  gray, 
  crossbedded 
  sandstones 
  

   with 
  flaggy 
  layers.

  a 
  

  

  Near 
  the 
  township 
  line 
  between 
  Franklin 
  and 
  Meredith 
  and 
  

   just 
  below 
  West 
  Meredith 
  are 
  ledges 
  of 
  red 
  shale 
  and 
  sandstone 
  

   on 
  the 
  hillside 
  a 
  little 
  south 
  of 
  the 
  road. 
  This 
  outcrop 
  is 
  about 
  

   55 
  feet 
  above 
  the 
  corners 
  at 
  West 
  Meredith. 
  Another 
  ledge 
  of 
  

   thin 
  bedded, 
  red 
  sandstone 
  30 
  feet 
  in 
  thickness 
  occurs 
  55 
  feet 
  

   higher 
  and 
  this 
  is 
  capped 
  by 
  similar 
  thin 
  bedded 
  gray 
  sandstone. 
  

   These 
  rocks 
  apparently 
  belong 
  in 
  the 
  Oneonta 
  sandstone 
  and 
  are 
  

   near 
  the 
  line 
  of 
  division 
  between 
  it 
  and 
  the 
  Chemung 
  as 
  mapped 
  

   on 
  the 
  Geologic 
  map 
  of 
  New 
  York. 
  On 
  a 
  loose 
  block 
  of 
  greenish 
  

   Chemung 
  sandstone 
  a 
  good 
  specimen 
  of 
  ScMzodus 
  chemungensis 
  

   (Con.) 
  Hall 
  was 
  found 
  and 
  in 
  the 
  red 
  sandstone 
  a 
  good 
  specimen 
  

   of 
  a 
  branching 
  algoid 
  plant. 
  Toward 
  the 
  divide 
  southeast 
  of 
  

   W'est 
  Meredith 
  and, 
  215 
  feet 
  higher 
  is 
  a 
  coarse, 
  massive 
  greenish 
  

   sandstone 
  which 
  as 
  represented 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  

   is 
  probably 
  in 
  the 
  Chemung. 
  

  

  When 
  the 
  sections 
  of 
  the 
  rocks 
  overlying 
  the 
  Oneonta 
  sand- 
  

   stone 
  at 
  West 
  Meredith, 
  Treadwell 
  and 
  Franklin 
  are 
  compared 
  

   with 
  the 
  synchronous 
  deposits 
  on 
  the 
  Susquehanna 
  river 
  at 
  Bain- 
  

   bridge 
  and 
  Afton, 
  the 
  far 
  greater 
  amount 
  of 
  coarse 
  grained 
  sand- 
  

   stone 
  is 
  at 
  once 
  noticed. 
  The 
  shales 
  and 
  somewhat 
  calcareous, 
  

   fossiliferous 
  layers 
  of 
  the 
  Susquehanna 
  valley 
  Chemung 
  seem 
  to 
  

   have 
  largely 
  disappeared 
  and 
  to 
  have 
  been 
  replaced 
  by 
  these 
  

   coarse 
  sandstones. 
  This 
  change 
  is 
  still 
  more 
  marked 
  to 
  the 
  east- 
  

   ward 
  in 
  the 
  drainage 
  area 
  of 
  the 
  Delaware 
  river 
  as 
  will 
  be 
  seen 
  

   in 
  the 
  description 
  of 
  that 
  region.
