  CHEMUNG 
  SERIES

  Catskill 
  formation 
  is 
  found 
  52 
  feet 
  higher. 
  A 
  piece 
  of 
  loose 
  

   sandstone 
  containing 
  a 
  specimen 
  of 
  Spirifer 
  mesastrialis 
  Hall 
  

   was 
  found 
  below 
  the 
  ledge 
  of 
  red 
  sandstone 
  but 
  I 
  am 
  hardly 
  

   inclined 
  to 
  think 
  that 
  it 
  came 
  from 
  the 
  upper 
  part 
  of 
  this 
  hill. 
  

   57 
  feet 
  above 
  the 
  red 
  sandstones 
  and 
  shales 
  occurs 
  another 
  

   ledge 
  — 
  A 
  12 
  — 
  of 
  grayish 
  thin 
  bedded 
  sandstones 
  which 
  are 
  939 
  

   feet 
  above 
  the 
  base 
  of 
  the 
  section. 
  The 
  rocks 
  are 
  then 
  covered 
  

   for 
  26 
  feet, 
  nearly 
  to 
  the 
  summit 
  of 
  the 
  hill, 
  making 
  a 
  section 
  

   of 
  approximately 
  965 
  feet 
  which 
  extends 
  from 
  the 
  upper 
  part 
  

   of 
  the 
  Oneonta 
  sandstone 
  into 
  the 
  lower 
  part 
  of 
  the 
  Catskill 
  

   formation.

  The 
  section 
  C 
  is 
  in 
  the 
  vicinity 
  of 
  Franklin 
  Station 
  

   on 
  the 
  New 
  York, 
  Ontario 
  and 
  Western 
  railroad, 
  three 
  and 
  one 
  

   half 
  miles 
  southeast 
  of 
  May 
  wood 
  and 
  near 
  the 
  line 
  between 
  Sidney 
  

   and 
  Franklin 
  townships. 
  On 
  the 
  bank 
  of 
  the 
  small 
  brook 
  below 
  

   Franklin 
  Station 
  and 
  east 
  of 
  the 
  railroad 
  cut 
  is 
  a 
  10 
  foot 
  ex- 
  

   posure 
  of 
  olive 
  to 
  gray 
  colored 
  sandstones 
  and 
  shales 
  containing 
  

   plenty 
  of 
  Crinoid 
  segments 
  with 
  a 
  few 
  other 
  fossils. 
  The 
  rocks 
  

   are 
  in 
  the 
  Chemung 
  formation. 
  

  

  LXVII

  . 
  In 
  the 
  railroad 
  cut 
  about 
  one 
  quarter 
  mile 
  northwest 
  

   of 
  Franklin 
  Station 
  is 
  an 
  exposure 
  of 
  28 
  feet 
  of 
  rocks 
  the 
  base 
  of 
  

   which 
  is 
  66 
  feet 
  above 
  C 
  1 
  . 
  The 
  rocks 
  consist 
  of 
  rather 
  thin 
  

   layers 
  of 
  sandstone 
  alternating 
  with 
  olive 
  and 
  blue 
  argillaceous 
  

   shales. 
  In 
  the 
  lower 
  part 
  of 
  the 
  cut 
  is 
  a 
  stratum 
  composed 
  partly 
  

   of 
  shale 
  and 
  partly 
  of 
  sandstone 
  which 
  has 
  very 
  irregular 
  struc- 
  

   ture 
  and 
  is 
  probably 
  somewhat 
  concretionary 
  in 
  form. 
  The 
  dip 
  

   varies 
  from 
  2j?° 
  to 
  3J° 
  S., 
  20° 
  E. 
  In 
  some 
  of 
  the 
  layers 
  fossils 
  

   are 
  common 
  and 
  in 
  the 
  rather 
  thin 
  layers 
  of 
  sandstone 
  quite 
  a 
  

   number 
  of 
  specimens 
  of 
  8pirifer 
  mesastrialis 
  Hall 
  were 
  found. 
  

   The 
  thin 
  olive 
  shales 
  and 
  sandstones 
  quite 
  closely 
  resemble, 
  litho- 
  

   logically, 
  the 
  typical 
  Chemung 
  rocks 
  of 
  southern 
  New 
  York. 
  

   The 
  fauna 
  of 
  this 
  zone 
  is 
  as 
  follows:

  Spirifer 
  mesastrialis
