The coal has too much sulphur and too large ash to be a first-class fuel. 



SHARON TOWNSHIP. 



This township lies south of Brookfield, and borders Morgan county on 

 the west. It is chiefly drained by the waters of Olive Green Creek. 

 There is considerable limestone in the hills, and the soil is generally 

 good. The Cumberland seam of coal is found in the high hills. In sec- 

 tion 1 the following geological section was taken :

(See Map XII., No. 18.) 



The coal is quite high in the hill, and had formerly been mined at 

 this point. All the higher hills should take the coal. By barometer the 

 height of the coal above Caldwell is about three hundred and forty feet. 

 From Sharon the coal dips pretty rapidly to the south, reaching the 

 Muskingum River at Coal Run ; but to the east there is very little dip. 



JACKSON TOWNSHIP. 



This township is situated in the south-west corner of the county, and 

 borders Washington county on the south and Morgan county on the west.
