  The 
  coal 
  from 
  No. 
  8 
  of 
  this 
  boring 
  appeared 
  to 
  he 
  of 
  excellent 
  

   quality 
  and 
  if 
  the 
  roof 
  proves 
  to 
  he 
  sufficiently 
  firm, 
  the 
  seam 
  can 
  

   he 
  worked 
  to 
  good 
  advantage. 
  Nos.

  represent 
  the 
  horizon 
  

   of 
  coal 
  No. 
  1, 
  divided 
  here 
  into 
  five 
  thin 
  seams 
  of 
  only 
  a 
  few 
  inches 
  

   in 
  thickness, 
  and 
  too 
  thin 
  in 
  the 
  aggregate 
  to 
  be 
  of 
  any 
  practical 
  

  

  value. 
  . 
  

  

  The 
  base 
  of 
  the 
  Coal 
  Measures 
  is 
  probably 
  the 
  hard 
  Bilwioue 
  rock

  while 
  Nos. 
  31

  the 
  St. 
  Louis 
  and 
  Warsaw 
  

   beds,

  all

  No.

  belong 
  to 
  the 
  Keokuk 
  

   limestone. 
  

  

  \„ 
  unsuccessful 
  attempt 
  to 
  obtain 
  coal 
  was 
  made 
  at 
  Parmer 
  City, 
  

   by 
  Binking 
  a 
  shaft 
  to 
  the 
  depth 
  of 
  10:5 
  feet 
  without 
  reaohing 
  bed- 
  

   rock 
  and 
  then 
  boring 
  to 
  the 
  depth 
  of 
  about 
  313 
  feel 
  below 
  the 
  

   bottom 
  Of 
  the 
  shaft, 
  making 
  a 
  total 
  depth 
  of 
  476 
  feet. 
  For 
  the 
  

   details 
  of 
  this 
  boring 
  I 
  am 
  indebted 
  to 
  Mr. 
  Bowdon, 
  under 
  whose 
  

   supervision 
  it 
  was 
  made.
