  They 
  are 
  hardly 
  in

  still 
  from 
  their 
  very 
  angular 
  

   shape 
  and 
  the 
  large 
  number 
  of 
  them

  LXVII 
  A 
  2 
  . 
  In 
  the 
  cut 
  immediately 
  west 
  of 
  Maywood 
  station 
  

   (formerly 
  Sidney 
  Center) 
  on 
  the 
  New 
  York, 
  Ontario 
  and 
  Western 
  

   railroad 
  there 
  is 
  an 
  exposure 
  of 
  34 
  feet 
  of 
  thin 
  sandstones 
  alter- 
  

   nating 
  with 
  shales. 
  Some 
  of 
  the 
  thin 
  layers 
  contain 
  large 
  num- 
  

   bers 
  of 
  Crinoid 
  segments, 
  and 
  the 
  rock 
  being 
  quite 
  calcareous 
  

   becomes 
  rotten 
  on 
  weathering 
  and 
  turns 
  from 
  a 
  greenish 
  to 
  a 
  

   brownish 
  color. 
  Some 
  of 
  the 
  shales 
  when 
  weathered 
  are 
  olive 
  

   but 
  on 
  a 
  fresh 
  surface 
  are 
  mostly 
  bluish. 
  The 
  bottom 
  of 
  the 
  rail- 
  

   road 
  cut 
  is 
  at 
  about 
  the 
  same 
  level 
  as 
  the 
  Maywood 
  station 
  which 
  

   is 
  1388 
  feet 
  A. 
  T. 
  The 
  dip 
  varies 
  for 
  the 
  different 
  strata 
  exposed 
  

   in 
  this 
  cut; 
  for 
  one 
  stratum 
  dips 
  about 
  1° 
  nearly 
  s. 
  e., 
  while 
  

   that 
  of 
  a 
  lower 
  thin 
  sandstone 
  stratum 
  varies 
  from 
  1J° 
  to 
  2^° 
  

   S. 
  10° 
  E. 
  In 
  number 
  of 
  species 
  and 
  specimens 
  Lamellibranchs 
  

   are 
  most 
  abundant 
  though 
  other' 
  fossils 
  are 
  common.
