  Great 
  credit 
  is 
  due 
  to 
  the 
  stockholders 
  in 
  this 
  mining 
  enterprise, 
  

   and 
  to 
  the 
  citizens 
  of 
  Mattoon 
  generally, 
  for 
  their 
  persevering 
  efforts 
  

   in 
  bringing 
  this 
  costly 
  experiment 
  to 
  a 
  successful 
  termination. 
  

  

  The 
  other 
  important 
  experiment 
  alluded 
  to 
  above, 
  was 
  made 
  with 
  

   the 
  diamond 
  drill 
  at 
  Pana, 
  and 
  was 
  successful 
  in 
  finding 
  a 
  coal 
  

   seam 
  about 
  seven 
  feet 
  in 
  thickness 
  at 
  the 
  depth 
  of 
  a 
  little 
  over 
  703 
  

   feet. 
  For 
  the 
  following 
  details 
  of 
  this 
  boring 
  I 
  am 
  indebted 
  to 
  J. 
  

   W. 
  Ketchell, 
  Esq., 
  of 
  Pana, 
  in 
  whose 
  office 
  I 
  was 
  permitted 
  to 
  ex- 
  

   amine 
  the 
  core 
  of 
  rock 
  taken 
  out 
  with 
  the 
  drill 
  as
