  When 
  I 
  visited 
  this 
  locality 
  in 
  October, 
  1882, 
  there 
  were 
  four 
  wells 
  

   in 
  operation, 
  producing 
  about 
  two 
  barrels 
  of 
  crude 
  oil 
  per 
  day 
  each. 
  

   The 
  product 
  is 
  a 
  heavy 
  lubricating 
  oil. 
  worth 
  considerably 
  more 
  in 
  

   thejnarket 
  than 
  the 
  common 
  petroleum. 
  It 
  comes, 
  apparently, 
  from 
  

   about 
  the 
  base 
  of 
  the 
  Coal 
  Measure 
  Conglomerate, 
  or 
  possibly 
  from 
  

   one 
  of 
  the 
  Upper 
  Chester 
  sandstones. 
  

  

  Nothing 
  definite 
  is 
  known 
  as 
  to 
  the 
  extent 
  of 
  the 
  area 
  over 
  which 
  

   this 
  oil 
  basin 
  extends, 
  as 
  no 
  boring 
  has 
  been 
  made 
  in 
  the 
  county 
  

   deep 
  enough 
  to 
  reach 
  the 
  oil-bearing 
  strata, 
  except 
  in 
  the 
  immediate 
  

   vicinity 
  of 
  Litchfield. 
  The 
  well 
  commenced 
  at 
  Irving 
  some 
  months 
  

   ago 
  may 
  throw 
  some 
  light 
  on 
  this 
  question 
  if 
  carried 
  to 
  the 
  depth 
  

   of 
  1,000 
  feet, 
  which 
  I 
  understand 
  to 
  be 
  the 
  requirement 
  of 
  the 
  orig- 
  

   inal 
  contract. 
  

  

  SALT 
  WELLS. 
  

  

  After 
  the 
  publication 
  of 
  the 
  report 
  on 
  Perry 
  county, 
  a 
  boring 
  WM 
  

   made 
  at 
  St. 
  Johns, 
  for 
  the 
  purpose, 
  mainly, 
  of 
  determining 
  whether 
  

   there 
  was 
  a 
  coal 
  seam 
  of 
  any 
  practical 
  value 
  below 
  the 
  DnQuoin 
  

   coal. 
  At 
  the 
  depth 
  of 
  970 
  feet 
  a 
  sandstone 
  saturated 
  with 
  salt 
  water 
  

   was 
  reached, 
  that 
  extended 
  to 
  the 
  depth 
  of 
  1,060 
  feet, 
  the 
  brine 
  ris- 
  

   ing 
  to 
  various 
  heights 
  from 
  150 
  to 
  260 
  feet 
  below 
  the 
  surface. 
  There 
  

   are 
  now 
  si\ 
  wells 
  in 
  operation 
  here, 
  with 
  a 
  flow 
  of 
  about 
  L6 
  gallon! 
  

   per 
  minute 
  to 
  each 
  well. 
  The 
  present 
  yield 
  of 
  merchantable 
  salt 
  at 
  

   these 
  works 
  is 
  stated 
  at 
  3,600 
  barrels 
  per 
  annum, 
  and 
  the 
  product 
  

  

  is 
  manufactured 
  into 
  the 
  various 
  grades 
  d 
  .-alt 
  in 
  common 
  use. 
  v> 
  

   rd 
  of 
  the 
  boring 
  could 
  be 
  obtained, 
  hut 
  two 
  thin 
  coals 
  were 
  re- 
  

   ported 
  as 
  ocourrring 
  below 
  the 
  DuQuoin 
  seam.
