  Of 
  the 
  six 
  lower 
  seams 
  represented 
  in 
  the 
  foregoing 
  condensed 
  

   section, 
  where 
  they 
  outcrop 
  in 
  the 
  valley 
  of 
  the 
  Illinois 
  river, 
  five 
  

   are 
  found 
  of 
  sufficient 
  thickness 
  to 
  be 
  profitably 
  mined 
  at 
  some 
  

   points 
  and 
  will 
  afford 
  an 
  aggregate 
  thickness 
  of 
  about 
  twenty 
  feet 
  

   of 
  marketable 
  coal. 
  They 
  are 
  not 
  everywhere 
  of 
  uniform 
  thickness, 
  

   however, 
  as 
  for 
  example, 
  No. 
  1, 
  at 
  Seville, 
  in 
  Fulton 
  county, 
  is 
  three 
  

   feet 
  or 
  more 
  in 
  thickness, 
  while 
  at 
  the 
  outcrop, 
  south 
  of 
  Lewistown, 
  

   on 
  the 
  north 
  bank 
  of 
  Spoon 
  river, 
  it 
  is 
  too 
  thin 
  to 
  be 
  profitably 
  

   mined. 
  At 
  Prairie 
  City 
  it 
  is 
  reported 
  at 
  3^ 
  feet 
  in 
  the 
  shaft 
  re- 
  

   cently 
  sunk 
  at 
  that 
  point, 
  while 
  in 
  the 
  vicinity 
  of 
  Colchester 
  it 
  is 
  

   nowhere 
  thick 
  enough 
  to 
  work, 
  and 
  is 
  often 
  absent 
  altogether, 
  or 
  

   represented 
  by 
  a 
  bed 
  of 
  bituminous 
  shale. 
  

  

  At 
  Eoodhouse, 
  in 
  Greene 
  county, 
  this 
  seam 
  was 
  reached 
  at 
  the 
  

   depth 
  of 
  about 
  ninety 
  feet, 
  passing 
  through 
  the

  This 
  is 
  probably 
  the 
  equivalent 
  of 
  the 
  Battery 
  Eock 
  coal, 
  which 
  out- 
  

   crops 
  in 
  the 
  bluffs 
  of 
  the 
  Ohio 
  river 
  a 
  few 
  miles 
  below 
  tbe 
  mouth 
  

   of 
  the 
  Saline, 
  and 
  is 
  there 
  associated 
  with 
  the 
  heavy 
  bed 
  of 
  con- 
  

   glomerate 
  that 
  forms 
  the 
  base 
  of 
  the 
  Coal 
  Measuress 
  in 
  Southern 
  

   Elinois. 
  The 
  coal 
  is 
  there 
  only 
  about 
  18 
  inches 
  thick, 
  and 
  the 
  

   mines 
  formerly 
  opened 
  there 
  have 
  generally 
  been 
  abandoned.
