  I 
  am 
  of 
  the 
  opinion 
  that 
  the 
  coal 
  seam 
  at 
  the 
  bottom 
  of 
  this 
  

   boring 
  is 
  number 
  sis 
  or 
  seven 
  of 
  the 
  general 
  section, 
  and 
  if 
  so, 
  

   number 
  five 
  would 
  be 
  found 
  from 
  fifty 
  to 
  seventy-five 
  feet 
  below, 
  

   and 
  would 
  probably 
  be 
  from 
  four 
  to 
  six 
  feet 
  in 
  thickness. 
  

  

  A 
  coal 
  shaft 
  has 
  been 
  sunk 
  at 
  Decatur 
  to 
  the 
  depth 
  of 
  about 
  600 
  

   feet, 
  but 
  I 
  have 
  not 
  been 
  able 
  to 
  obtain 
  any 
  reliable 
  information 
  in 
  

   regard 
  to 
  it, 
  further 
  than 
  a 
  copy 
  of 
  the 
  published 
  record 
  of 
  tbe 
  

   boring 
  made 
  previous 
  to 
  sinking 
  the 
  shaft. 
  I 
  visited 
  the 
  locality 
  

   shortly 
  after 
  the 
  shaft 
  was 
  completed, 
  and 
  found, 
  by 
  an 
  examina- 
  

   tion 
  of 
  the 
  roof 
  shales, 
  that 
  it 
  was 
  probably 
  coal 
  No. 
  5, 
  and 
  was 
  

   told 
  that 
  it 
  was 
  about 
  four 
  and 
  a 
  half 
  feet 
  in 
  thickness, 
  although 
  

   the 
  published 
  record 
  of 
  the 
  boring 
  gives 
  but 
  three 
  feet 
  six 
  inches 
  

   as 
  the 
  thickness 
  of 
  the 
  coal. 
  For 
  the 
  privilege 
  of 
  copying 
  this 
  

   record 
  from 
  a 
  Decatur 
  paper 
  I 
  am 
  indebted 
  to 
  Mr. 
  Stoddard, 
  of 
  

   Mattoon. 
  That 
  this 
  boring 
  is 
  not 
  quite 
  reliable, 
  is 
  shown 
  by 
  the 
  

   fact 
  that 
  it 
  records 
  a 
  six 
  foot 
  one 
  inch 
  seam 
  of 
  coal 
  at 
  the 
  depth 
  

   of 
  413 
  feet, 
  while 
  the 
  shaft 
  was 
  sunk 
  to 
  the 
  depth 
  of 
  about 
  600 
  

   feet 
  to 
  a 
  seam 
  but 
  little 
  more 
  than 
  two-thirds 
  the 
  thickness 
  of 
  the 
  

   one 
  reported 
  above. 
  The 
  coal 
  passed 
  through 
  at 
  the 
  depth 
  of 
  413 
  

   feet 
  was 
  probably 
  coal 
  No. 
  8 
  of 
  the 
  general 
  section, 
  which 
  seldom 
  

   exceeds 
  two 
  feet 
  in 
  thickness, 
  and 
  is 
  often 
  replaced 
  entirely 
  by 
  bitu- 
  

   minous 
  shale.
