  hill 
  over 
  two 
  miles 
  northwest 
  of 
  Bainbridge 
  

   and 
  135 
  feet 
  above 
  the 
  base

  the

  olive 
  

   shales 
  outcrop

  On 
  the

  these

  called 
  A

  . 
  No 
  fossils 
  were 
  discovered 
  

   though 
  this 
  may 
  be 
  due 
  to 
  the 
  fact 
  that 
  very 
  little 
  time 
  could 
  be 
  

   spent 
  in 
  searching 
  for 
  them. 
  

  

  LXVIII

  1 
  . 
  Near 
  the 
  southeastern 
  corner 
  of 
  Bainbridge 
  is 
  the 
  

   small 
  village 
  of 
  Bennettsville 
  just 
  below 
  which 
  on 
  Bennett's 
  

   creek 
  is 
  a 
  mill. 
  On 
  the 
  north 
  bank 
  of 
  the 
  creek 
  directly 
  above 
  the 
  

   highway 
  and 
  below 
  the 
  dam 
  are 
  ledges 
  of 
  thin 
  sandstones 
  and 
  

   bluish, 
  slightly 
  arenaceous 
  shales 
  containing 
  small 
  Lamellibranch 
  

   shells 
  of 
  which 
  Leptodesma 
  sociale 
  Hall, 
  Orthonota 
  undmlata 
  Con., 
  

   and 
  Lunulicardium 
  fragile 
  Hall 
  are 
  the 
  most 
  common. 
  Fossils 
  are 
  

   not 
  abundant 
  and 
  though 
  in 
  the 
  upper 
  part 
  of 
  the 
  exposure 
  some 
  

   calcareous 
  layers, 
  composed 
  largely 
  of 
  crinoid 
  segments, 
  are 
  seen, 
  

   still 
  none 
  of 
  those 
  strongly 
  calcareous 
  layers 
  containing 
  numer- 
  

   ous 
  Brachiopods, 
  that 
  occur 
  rather 
  frequently 
  in 
  the 
  fossiliferous 
  

   beds 
  of 
  the 
  lower 
  Chemung 
  of 
  this 
  region, 
  were 
  found. 
  The 
  base 
  

   of 
  the 
  rocks 
  is 
  approximately 
  65 
  feet 
  above 
  the 
  level 
  of 
  the 
  

   Susquehanna 
  river, 
  and 
  in 
  the 
  bank 
  29 
  feet 
  are 
  exposed. 
  The 
  

   following 
  species 
  were 
  collected:
