  Kanopolis, 
  thinning 
  out 
  northward. 
  Thus 
  the 
  salt 
  beds 
  at 
  King- 
  

   man 
  are 
  415 
  feet 
  in 
  thickness; 
  at 
  Hutchinson, 
  380 
  feet; 
  at 
  Lyons, 
  

   2V5 
  feet, 
  and 
  at 
  Kanopolis 
  only 
  25 
  0. 
  At 
  this 
  rate 
  they 
  would 
  

   disappear 
  entirely 
  before 
  the 
  north 
  line 
  of 
  the 
  State 
  is 
  reached. 
  

   It 
  is 
  a 
  remarkable 
  fact 
  that 
  the 
  usual 
  gypsum 
  deposits 
  do 
  not 
  

   seem 
  to 
  be 
  present 
  at 
  localities 
  just 
  named, 
  though 
  largely 
  repre- 
  

   sented 
  to 
  the 
  northeast 
  in 
  Marshall 
  County. 
  In 
  regard 
  to 
  this, 
  

   Professor 
  Haworth 
  writes 
  : 
  

  

  " 
  It 
  is 
  difficult 
  to 
  understand 
  how 
  such 
  extensive 
  deposits 
  of 
  

   salt 
  could 
  be 
  formed 
  without 
  a 
  larger 
  amount 
  of 
  gypsum 
  being 
  

   formed 
  underneath 
  them. 
  The 
  records 
  of 
  the 
  wells 
  at 
  Kanopolis, 
  

   Lyons, 
  Hutchinson, 
  Kingman 
  and 
  Anthony 
  contain 
  no 
  reference 
  

   to 
  gypsum 
  immediately 
  underlying 
  the 
  salt 
  beds. 
  The 
  question 
  

   is 
  as 
  to 
  what 
  became 
  of 
  the 
  calcium 
  sulphate 
  held 
  in 
  solution 
  by 
  

   the 
  ocean 
  water 
  from 
  which 
  the 
  rock 
  salt 
  was 
  obtained. 
  It 
  is 
  

   barely 
  possible 
  that 
  during 
  the 
  period 
  of 
  the 
  formation 
  of 
  the 
  

   Marshall 
  County 
  gypsum 
  the 
  inland 
  sea 
  did 
  not 
  reach 
  southward 
  

   to 
  the 
  salt 
  beds 
  area, 
  and 
  that 
  after 
  gypsum 
  was 
  principally 
  pre- 
  

   cipitated 
  out 
  of 
  the 
  enclosed 
  ocean 
  water 
  and 
  before 
  concentration 
  

   was 
  carried 
  far 
  enough 
  to 
  precipitate 
  the 
  salt, 
  surface 
  movements 
  

   resulted 
  in 
  draining 
  this 
  partially 
  purified 
  water 
  southward 
  over 
  

   new 
  areas 
  from 
  which 
  fresh 
  ocean 
  water 
  was 
  excluded, 
  thus 
  per- 
  

   mitting 
  the 
  continued 
  evaporation 
  to 
  deposit 
  the 
  salt 
  now 
  found 
  

   in 
  the 
  salt 
  beds 
  from 
  the 
  same 
  water 
  from 
  which 
  the 
  Marshall 
  

   County 
  gypsum 
  was 
  produced. 
  It 
  is 
  known 
  that 
  the 
  Permian 
  

   rocks, 
  in 
  general, 
  become 
  quite 
  thin 
  northward, 
  entirely 
  exclud- 
  

   ing 
  the 
  upper 
  members 
  of 
  the 
  Permian. 
  So 
  far 
  as 
  this 
  has 
  a 
  

   bearing 
  on 
  the 
  subject, 
  it 
  would 
  tend 
  to 
  favor 
  the 
  view 
  just 
  

   expressed."
