  1403' 
  

  

  Between 
  1388 
  and 
  1390, 
  with 
  an 
  irregular 
  but 
  quite 
  dis- 
  

   tinct 
  line 
  of 
  separation 
  from 
  the 
  mixed 
  salt 
  above, 
  the 
  bed 
  

   becomes 
  nearly 
  homogenous, 
  and 
  shows 
  in 
  clear, 
  bluish, 
  almost 
  

   transparent, 
  or 
  whiter, 
  more 
  opaque 
  layers 
  of 
  salt 
  in 
  straight 
  

   bands 
  on 
  the 
  walls 
  of 
  the 
  shaft, 
  abundant 
  evidences 
  of 
  deposi- 
  

   tion. 
  The 
  salt 
  crystals 
  are 
  somewhat 
  finer 
  than 
  in 
  the 
  mixed 
  

   salt 
  above. 
  There 
  appears 
  to 
  be 
  very 
  little 
  impurity 
  of 
  any 
  

   kind 
  in 
  the 
  salt.

  Dark 
  gray, 
  hard 
  limestone, 
  in 
  layers 
  4" 
  to 
  8" 
  thick, 
  

   containing 
  much 
  salt 
  in 
  veins 
  and 
  seams 
  and 
  in 
  crystals 
  1 
  mm. 
  

   to 
  2 
  mm. 
  in 
  diameter, 
  which 
  diss 
  >lve 
  when 
  the 
  rock 
  is 
  immersed 
  

   in 
  water, 
  leaving 
  it 
  cellular 
  and 
  friable.
