  I 
  am 
  not 
  able 
  to 
  correlate 
  this 
  boring, 
  either 
  with 
  the 
  shaft 
  at 
  

   Mattoon 
  or 
  the 
  diamond 
  drill 
  boring 
  at 
  Pana. 
  I 
  am 
  satisfied 
  that 
  

   it 
  is 
  not 
  deep 
  enough 
  to 
  reach 
  the 
  horizon 
  of 
  coal 
  No. 
  5, 
  but 
  it 
  is 
  

   possible 
  that 
  the 
  lowest 
  coal 
  reported 
  in 
  the 
  boring 
  may 
  be 
  No. 
  7, 
  

   and 
  if 
  this 
  conclusion 
  is 
  correct, 
  No. 
  5 
  would 
  be 
  found 
  at 
  from 
  60 
  

   to 
  75 
  feet 
  below. 
  The 
  limestones 
  reported 
  in 
  this 
  boring 
  have 
  no 
  

   analogues 
  any 
  where 
  else 
  in 
  the 
  Coal 
  Measures, 
  either 
  in 
  the 
  num- 
  

   ber 
  of 
  the 
  beds 
  or 
  their 
  aggregate 
  thickness. 
  Nos. 
  6, 
  8 
  and 
  11 
  

   constitute 
  a 
  calcareous 
  mass 
  31 
  feet 
  in 
  thickness, 
  with 
  only 
  about 
  

   8 
  feet 
  of 
  intervening 
  shales, 
  and 
  in 
  my 
  examinations 
  of 
  the 
  outcrops 
  

   on 
  the 
  Embarras 
  river, 
  in 
  this 
  and 
  the 
  adjoining 
  county 
  of 
  Cum- 
  

   berland, 
  no 
  such 
  heavy 
  beds 
  of 
  limestone 
  were 
  found. 
  

  

  The 
  "Fusulina" 
  limestone 
  which 
  outcrops 
  in 
  the 
  vicinity 
  of 
  Green- 
  

   up, 
  and 
  along 
  the 
  Embarras 
  river 
  at 
  intervals 
  nearly 
  to 
  the 
  south 
  

   line 
  of 
  Coles 
  county, 
  is 
  nowhere 
  more 
  than 
  five 
  feet 
  in 
  thickness, 
  

   and 
  I 
  found 
  no 
  calcareous 
  shales 
  of 
  any 
  considerable 
  thickness 
  

   associated 
  with 
  it 
  that 
  could 
  be 
  mistaken 
  in 
  the 
  boring 
  for 
  lime- 
  

   stone. 
  This 
  may 
  be 
  represented, 
  however, 
  by 
  No. 
  6 
  of 
  the 
  boring, 
  

   and 
  the 
  20 
  foot 
  limestone 
  No. 
  8 
  may 
  be 
  the 
  equivalent 
  of 
  the 
  

   Quarry 
  Creek 
  limestone 
  of 
  Clark 
  county, 
  '[which 
  is 
  underlaid 
  by 
  a 
  

   green 
  shale 
  there, 
  and 
  possibly 
  agreeing 
  with 
  that 
  reported 
  under 
  

   the 
  limestone 
  in 
  this 
  boring. 
  Below 
  this 
  there 
  are 
  four 
  other 
  beds 
  

   of 
  limestone 
  reported, 
  varying 
  in 
  thickness 
  from 
  six 
  to 
  twenty 
  feet, 
  

   making 
  an 
  aggregate 
  of 
  some 
  80 
  or 
  90 
  feet. 
  If 
  this 
  is 
  a 
  true 
  record 
  

   of 
  the 
  Coal 
  Measure 
  strata 
  underlying 
  Coles 
  county, 
  it 
  shows 
  a 
  

   greater 
  thickness 
  of 
  calcareous 
  beds 
  here 
  than 
  have 
  been 
  found 
  else- 
  

   where 
  in 
  the 
  State.
