  feet 
  of 
  rocks 
  

   from 
  the

   base

  . 
  In 
  the 
  northwestern 
  part 
  of 
  Bainbridge 
  village 
  

   along 
  the 
  stream 
  from 
  the 
  northwest 
  is 
  a 
  small 
  glen 
  which 
  is 
  quite 
  

   narrow 
  and 
  for 
  some 
  distance 
  bounded 
  by 
  walls 
  exposing 
  70 
  feet 
  

   of 
  rock, 
  the 
  base 
  of 
  which 
  is 
  about 
  80 
  feet 
  above 
  the 
  level 
  of 
  the 
  

   Park 
  hotel 
  in 
  the 
  central 
  part 
  of 
  the 
  village. 
  The 
  rocks 
  consist 
  

   mostly 
  of 
  bluish 
  shales 
  and 
  thin 
  sandstones 
  with 
  one 
  or 
  two 
  irreg- 
  

   ular 
  slightly 
  concretionary 
  strata. 
  'The 
  shales 
  are 
  fairly 
  f 
  ossifer- 
  

   ous, 
  specially 
  in 
  certain 
  layers, 
  while 
  in 
  the 
  sandstones 
  a 
  smaller 
  

   number 
  of 
  fossils 
  is 
  found. 
  There 
  are 
  frequently 
  somewhat 
  calcare- 
  

   ous 
  layers 
  in 
  which 
  occur 
  great 
  numbers 
  of 
  crinoid 
  segments. 
  The 
  

   lower 
  shales 
  contain 
  numerous 
  specimens 
  of 
  Spirifer 
  irmcronatus 
  

   (Con.) 
  Bill. 
  var. 
  posterus 
  Hall 
  & 
  Clarke 
  which 
  occurs 
  in 
  all 
  of 
  the 
  

   rocks 
  of 
  this 
  zone. 
  In 
  the 
  upper 
  part 
  of 
  the 
  glen 
  are 
  layers 
  con- 
  

   taining 
  many 
  specimens 
  of 
  LiorJiynclius 
  glohuliformis 
  (Van.) 
  Hall; 
  

   a 
  smaller 
  number 
  of 
  Productella 
  lachrymosa 
  (Con.) 
  Hall 
  and 
  very 
  

   large 
  specimens 
  of 
  Atrypa 
  reticula?*is 
  (Linn.) 
  Dal.
