270 GEOLOGY OF OHIO. 
The bituminous shale contains numerous thin streaks of coal, which 
are occasionally aggregated so as to form a layer one inch. The coal is so 
superlatively bad throughout at this opening that no effort was made to 
trace the pyrites bands. Pyrites abounds in all parts, and the outcrop is 
incrusted with copperas. The coal burns well, and, according to Mr. 
Campbell, does not clinker. The sandstone frequently displaces the 
shales, and rests directly on the coal. At this locality No. 10 was worked 
at one time, but the opening is deserted. 
Mr. John Gibson, in section 29, works Coal No. 10. His opening was 
so full of water when visited that no measurement could be made, but the 
coal is said to be three and one-half feet thick. It is hard to dig, and is 
regarded as inferior to that obtained from Mr. Campbell’s bank. In the 
same section Mr. John Cheney also works Coal No. 10, and finds it three 
feet thick, and of fair quality for use in the grate. In sections 16 and 22 
the same bed is worked. In section 16 Mr. Walter Davy has it only two 
feet ten inches, while at Mr. George Douglass’s bank, in section 22, we 
find slaty coal one foot six inches, and coal seen three feet. At many 
localities this coal is so bad that it seems good for little else but the manu- 
facture of copperas. Mr. Davy’s bank is thought to yield better coal than 
the others, and the following is the result of an analysis:

The peculiarities of Coal No. 11 are well shown in the second cut west 
of Barnesville, where it gives the following section:
