In  the  fall  of  1903  this  bank  was  delivering-  2,500  bushels  a  month 
to  the  steam  shovels  working  on  the  B.  R.  and  P.  Railroad  cut  near 
Parkwood,  and  the  Madison  Craig  bank  (No.  2)  was  working  on  a 
similar  order. 
These  northern  banks  in  the  Elders  Ridge  held  furnish  a  large  part 
of  the  local  suppky  in  the  Crooked  Creek  Valley.  Being  compact  and 
hard,  the  Pittsburg  coal  comes  out  of  the  mine  in  firm  blocks,  which, 
in  spite  of  their  impurities,  are  preferred  by  the  farmers  for  use  in 
stoves  and  grates  to  the  softer  coal  from  the  Upper  Freeport  seam  as 
mined  on  Crooked  Creek. 
At  the  J.  D.  Hart  bank  (No.  6)  on  Whiskey  Run,  1  mile  southwest 
of  West  Lebanon,  the  entire  thickness  of  the  coal  was  not  seen.  Two 
bands  of  roof  coal,  8  and  3  inches  thick,  are  said  to  be  above  the  draw 
slate  and  are  not  taken  down.  The  main  part  of  the  seam  comprises 
5^  feet  of  good  coal,  with  only  two  thin  partings.

The  thickest  section  of  Pittsburg  coal  measured  by  the  writer  is  in 
this  northern  block  on  the  farm  of  Thomas  Campbell.  Back  of  his 
house,  which  is  li  miles  south  of  West  Lebanon,  there  is  a  small  ravine 
in  which  the  coal  is  well  exposed  and  headings  have  been  driven.  The 
seam  is  in  three  benches,  the  middle  one  being  nearly  5i  feet  thick. 
The  section  is  as  follows:
