Bed of Saltpetre Creek. 



The coal is generally of fair quality, and will answer for all the ordi- 

 nary uses, but it contains too much sulphur for the highest uses. 



On the land of Edward Okey, on Road Fork, in this township, the 

 Cumberland seam of coal is seen, with a thickness of the lower bench of 

 four feet eight inches. Above the clay parting is the upper bench, from 

 six inches to one foot thick. Six feet of shale separate this bench from 

 twenty-five feet of overlying sandrock. The following analysis was 

 made by Prof. Wormley of a sample of the coal of the lower bench : 



Specific gravity ; 1.419 



Moisture 1-10 



Ash 10.20 



Volatile combustible matter 32.90 



Fixed carbon 55-80 



Total 10000 



Sulphur 3 - 48 



Permanent gas in cubic feet 3.01
