  throughout

  The 
  dip 
  shown 
  there 
  is 
  southeast. 
  That 
  

   is, 
  if 
  these 
  really 
  represent, 
  as 
  they 
  seem 
  to, 
  lines 
  of 
  stratifica- 
  

   tion, 
  the 
  salt 
  is 
  almost 
  vertical. 
  Pomeroy 
  states 
  however 
  that 
  a 
  

   close 
  examination 
  reveals 
  the 
  fact 
  that 
  the 
  salt 
  is 
  folded, 
  the 
  upper 
  

   level 
  showing 
  three 
  distinct 
  anticlines.

  The 
  remarkable 
  purity 
  of 
  the 
  salt 
  and 
  

   the 
  absence 
  of 
  the 
  usual 
  impurities 
  found 
  in 
  other 
  rock 
  salt 
  

   deposits 
  has 
  been 
  the 
  subject 
  of 
  quite 
  a 
  good 
  deal 
  of 
  comment 
  

   and 
  is 
  one 
  of 
  the 
  hardest 
  points 
  to 
  meet 
  in 
  a 
  rational 
  explanation 
  

   of 
  its 
  origin. 
  Quite 
  a 
  number 
  of 
  analyses 
  have 
  been 
  made, 
  of 
  

   which 
  the 
  following 
  are 
  the 
  most 
  important.

  Yearly

   yearly

  at

  that 
  the 
  

   output 
  reached 
  its 
  maximum 
  shortly 
  after 
  the 
  completion 
  of
