  protruding 
  salt 
  mass 
  and 
  a 
  second 
  greater 
  movement 
  which 
  

   resulted 
  in 
  the 
  tipping 
  of 
  the 
  lignite 
  at 
  an 
  angle 
  of 
  44°. 
  

  

  The 
  stratigraphical 
  position 
  of 
  the 
  gravel 
  seems 
  to 
  be 
  above 
  

   the 
  lignite 
  and 
  its 
  position 
  on 
  the 
  southern 
  end 
  of 
  the 
  island 
  

   would 
  thus 
  be 
  readily 
  explained. 
  Although 
  the 
  position 
  of 
  the 
  

   gravel 
  could 
  be 
  almost 
  as 
  well 
  accounted 
  for 
  by 
  the 
  supposition 
  

   of 
  a 
  deposition 
  prior 
  to 
  the 
  first 
  movement. 
  Of 
  the 
  cla}^ 
  beds, 
  

   part 
  are 
  undoubtedly 
  older 
  than 
  the 
  lignite, 
  indeed 
  the 
  direction 
  

   of 
  the 
  dip 
  would 
  make 
  the 
  bulk 
  of 
  the 
  under 
  cla^^s 
  on 
  the 
  north- 
  

   ern 
  end 
  of 
  the 
  island 
  older. 
  

  

  There 
  are 
  some 
  facts 
  bearing 
  on 
  the 
  date 
  of 
  the 
  last 
  movement. 
  

   The 
  vertebrate 
  remains 
  found 
  in 
  mine 
  valley 
  show 
  no 
  trace 
  of 
  

   erosion, 
  so 
  the^^ 
  can 
  hardly 
  be 
  regarded 
  as 
  having 
  been 
  trans- 
  

   ported 
  by 
  the 
  same 
  agent 
  that 
  brought 
  the 
  gravel. 
  The 
  animals, 
  

   which 
  the 
  bones 
  represent, 
  in 
  all 
  probability 
  ventured 
  into 
  the 
  

   valley 
  for 
  salt 
  and 
  became 
  mired 
  in 
  the 
  mud 
  which 
  surrounded 
  

   the 
  lick 
  or 
  spring. 
  Such 
  deposits 
  in 
  the 
  mire 
  about 
  salt 
  springs 
  

   are 
  not 
  at 
  all 
  uncommon. 
  The 
  bone 
  bed 
  was 
  formed 
  after 
  the 
  

   elevation 
  of 
  the 
  island 
  and 
  the 
  bones 
  represent 
  Pleistocene 
  

   mammalia.

  The 
  potshreds 
  and 
  other 
  remains 
  

   which 
  have 
  been 
  mentioned 
  above 
  as 
  indicating 
  the 
  former 
  use 
  of 
  

   the 
  salt 
  by 
  the 
  Indians, 
  seem 
  to 
  have 
  been 
  first 
  seen 
  in 
  the 
  exca- 
  

   vations 
  made 
  during 
  the 
  war. 
  Owen 
  on 
  his 
  visit 
  to 
  the 
  island 
  

   (1865) 
  found 
  fragments 
  of 
  pottery 
  scattered 
  over 
  the 
  old 
  dump 
  

   heaps. 
  

  

  About 
  that 
  time 
  Prof. 
  Joseph 
  Henry 
  figured 
  and 
  described 
  in 
  

   the 
  Transactions 
  of 
  the 
  Chicago 
  Academy 
  of 
  Sciences 
  a 
  fragment 
  

   of 
  cane 
  basket 
  work 
  from 
  Petite 
  Anse 
  received 
  from 
  Mr. 
  T. 
  F. 
  

   Cleu 
  with 
  the 
  statement 
  that 
  it 
  had 
  been 
  found 
  directly 
  on 
  the 
  

   salt 
  two 
  feet 
  beneath 
  elephant 
  remains.*

  formed
