  remarks 
  that 
  none 
  of 
  the 
  bones 
  examined 
  by 
  him 
  showed 
  

   any 
  trace 
  of 
  erosion 
  ; 
  a 
  statement 
  which 
  is 
  confirmed 
  by 
  all 
  the 
  

   specimens 
  collected 
  by 
  the 
  writer. 
  Just 
  south 
  of 
  the 
  new 
  shaft 
  

   in 
  grading 
  for 
  the 
  railroad 
  embankment 
  what 
  appears 
  to 
  have 
  

   been 
  a 
  fairly 
  complete 
  skeleton 
  of 
  a 
  mastodon 
  was 
  unearthed 
  

   and 
  before 
  it 
  was 
  seen 
  by 
  any 
  one 
  who 
  realized 
  its 
  value 
  it 
  was 
  

   buried 
  in 
  the 
  embankment. 
  A 
  few 
  bones 
  which 
  had 
  rolled 
  

   down 
  to 
  the 
  foot 
  of 
  the 
  embankment 
  were 
  picked 
  up 
  by 
  General 
  

   Avery 
  and 
  led 
  to 
  the 
  disclosure 
  of 
  the 
  above 
  facts. 
  About 
  three 
  

   feet 
  of 
  a 
  tusk 
  was 
  afterwards 
  found 
  by 
  one 
  of 
  the 
  workmen 
  in 
  

   the 
  side 
  of 
  the 
  embankment. 
  

  

  A 
  few 
  stray 
  bones 
  have 
  been 
  found 
  in 
  Iron 
  mine 
  run 
  above 
  

   the 
  bridge. 
  These 
  are 
  the 
  only 
  two 
  localities 
  where 
  bones 
  have 
  

   been 
  found 
  outside 
  of 
  the 
  lowest 
  part 
  of 
  Salt 
  mine 
  valley.

  ^Just 
  west 
  of 
  the 
  last 
  section 
  the 
  new 
  

   shaft 
  shows 
  very 
  little 
  in 
  common 
  with 
  the 
  bone-bed 
  section.

  5- 
  Salt 
  

  

  The 
  salt. 
  — 
  The 
  salt 
  is 
  white, 
  hard, 
  dry, 
  crystalline, 
  commonly 
  

   composed 
  of 
  many 
  small 
  crystsls 
  from 
  an 
  eighth 
  to 
  a 
  quarter 
  of 
  

   inch 
  in 
  diameter 
  which 
  are 
  very 
  irregular 
  because 
  of 
  interference. 
  

   Occasionally 
  masses 
  are 
  found 
  which 
  are 
  composed 
  of 
  very 
  large 
  

   crystals 
  as 
  shown 
  on 
  Plate 
  23. 
  The 
  salt 
  here 
  shows 
  nothing 
  of 
  

   the 
  upper 
  dirty 
  salt 
  found 
  on 
  Belle 
  Isle 
  but 
  is 
  quite 
  white 
  so 
  far 
  

   as 
  penetrated, 
  with 
  the 
  exception 
  of 
  parallel 
  bands 
  of 
  dark 
  salt 
  

   from 
  two 
  to 
  six 
  inches 
  thick. 
  These 
  are 
  best 
  shown 
  on 
  a 
  freshly 
  

   blasted 
  face. 
  Analysis 
  of 
  this 
  black 
  salt 
  by 
  Mr. 
  McCalla, 
  at 
  

   one 
  time 
  resident 
  engineer 
  and 
  chemist, 
  shows 
  that 
  the 
  black 
  

   bands 
  contain 
  seven 
  per 
  cent 
  of 
  insoluble 
  matter, 
  chiefly 
  gypsum. 
  

  

  Access 
  could 
  be 
  had 
  to 
  only 
  a 
  very 
  small 
  portion 
  of 
  the 
  mine, 
  

   at 
  the 
  time 
  of 
  the 
  writer's 
  visit 
  but 
  Mr. 
  John 
  Avery, 
  Assistant 
  

   Superintendent, 
  states 
  that 
  the 
  extravagant 
  dip 
  shown 
  on 
  the 
  

   present 
  working 
  face 
  is 
  the 
  same 
  both 
  in 
  intensity 
  and 
  direction
