  which 
  is 
  here 
  given; 
  at 
  the 
  top 
  is 
  a 
  cascade 
  also 
  shown 
  on 
  

   the 
  plate, 
  and 
  at 
  the 
  top 
  of 
  that 
  is 
  a 
  dam. 
  The 
  land 
  on 
  the 
  west- 
  

   ern 
  side 
  of 
  the 
  gulf 
  belongs 
  to 
  Mr 
  William 
  Hannahs 
  and 
  on 
  the 
  

   eastern 
  side 
  to 
  Mr 
  David 
  Wilday. 
  In 
  part 
  2 
  of 
  the 
  magnificent 
  

   work 
  on 
  the 
  Lamellibranchiata 
  of 
  New 
  York 
  a 
  number 
  of 
  species 
  

   are 
  credited 
  to 
  this 
  locality 
  and 
  it 
  is 
  certainly 
  a 
  splendid 
  place 
  

   for 
  collecting. 
  There 
  are 
  numerous 
  large 
  blocks 
  in 
  the 
  stream 
  

   which 
  have 
  fallen 
  from 
  the 
  cliffs 
  along 
  the 
  sides 
  of 
  the 
  gulf 
  and 
  

   they 
  are 
  filled 
  with 
  excellent 
  fossils. 
  On 
  the 
  section 
  A 
  7 
  and 
  A 
  8 
  

   are 
  the 
  exposures 
  for 
  Bear's 
  gulf, 
  the 
  lower 
  235 
  feet 
  of 
  which 
  

   are 
  composed 
  largely 
  of 
  coarse 
  arenaceous 
  shales 
  containing 
  an 
  

   abundance 
  of 
  fossils, 
  while 
  at 
  their 
  top 
  is 
  the 
  base 
  of 
  the 
  high 
  

   cliff. 
  The 
  cliff 
  is 
  composed 
  of 
  shales 
  with 
  rather 
  thick, 
  very 
  

   fossiliferous 
  sandstones 
  and 
  it 
  is 
  180 
  feet 
  from 
  its 
  base 
  to 
  the 
  

   dam 
  at 
  the 
  head 
  of 
  the 
  gulf. 
  Time 
  did 
  not 
  permit 
  a 
  thorough 
  

   search 
  for 
  fossils; 
  but 
  the 
  following 
  fauna 
  was 
  obtained 
  from 
  

   sones 
  A

  and
