  Pomeroy's

  confined

  Bolto7i. 
  — 
  Early 
  in 
  1888 
  Dr. 
  H. 
  Carrington 
  Bolton 
  read 
  a 
  paper 
  

   before 
  the 
  New 
  York 
  Academy 
  of 
  Science 
  on 
  the 
  ' 
  ' 
  Great 
  Salt 
  

   Deposits 
  of 
  Petite 
  Anse.

  He 
  mentions 
  the 
  occurrence 
  of 
  lignite 
  

   and 
  sandstone 
  north 
  of 
  the 
  shaft 
  in 
  Iron 
  Mine 
  run 
  and 
  concludes 
  

   from 
  the 
  direction 
  (S. 
  E.) 
  of 
  the 
  dip 
  that 
  it 
  must 
  pass 
  beneath 
  

   the 
  salt. 
  The 
  black 
  bands 
  in 
  the 
  salt, 
  he 
  states, 
  contain 
  about 
  

   seven 
  per 
  cent, 
  of 
  insoluble 
  matter 
  chiefly 
  gypsum 
  and 
  form 
  well 
  

   marked 
  folds, 
  from 
  which 
  he 
  concludes 
  that 
  at 
  some 
  time 
  the 
  

   salt 
  has 
  been 
  submitted 
  to 
  lateral 
  pressure.

  The 
  discovery 
  of 
  numerous 
  vertebrate 
  remains 
  on 
  Petite 
  

   Anse 
  in 
  an 
  attempt 
  to 
  sink 
  a 
  shaft 
  in 
  1890 
  was 
  the 
  occasion 
  of 
  a

  Although 
  neither 
  Lerch

   visited 
  the 
  Five 
  Islands 
  their 
  diametrically

  views 
  on 
  the 
  

   origin 
  of 
  the 
  various 
  Cretaceous 
  outcrops

  based 
  on 
  

   observations 
  in 
  northern 
  Ivouisiana 
  early 
  in
