7170 GEOLOGY OF OHIO. 
In this important section, two things are worthy of note: First, that 
the interval between 8 and 8c has diminished, within four miles, from 
thirty-eight feet to less than fourteen, a difference of twenty-four feet; 
and, second, that the limestone above 8, the same which, in Belmont and 
Harrison counties, underlies Coal No. 9, is rapidly thinning out, having 
thus far decreased from sixty feet on Little Short Creek, to barely six feet 
at the locality of this section. If, now, we go to the western portion of 
the township, we find, about one-half mile north from York, the follow- 
ing section exposed in the road

Here all the limestones have disappeared, and the interval between 
Coal No. 8 and the sandstone under Coal No. 10 has been reduced to ten 
feet, while the sandstone under 10 has thickened from sixty feet in the 
previous section to eighty-five in this. It is somewhat difficult to assign 
the thin coal properly, but it seems to be Coal No. 9, as that coal occupies 
about that horizon in the adjoining portion of Harrison county. 
Near Smithfield, Coal No. 8 is worked by Mr. Cope, at whose bank the 
bed is as follows: :

The pyrites band is one foot from the top, and only one-fifth of an inch 
thick. There are no well-defined partings. Thecoalis very good. Near 
Wood’s Mills, we find Mr. N. R. Wood’s opening, which shows—

The roof coal is not very good, being more or less rotten. The main 
coal shows a parting two inches thick, nearly midway. Toward the bot- 
tom it contains large lenticular nodules of pyrites. The coal is very soft. 
Mr. J. Sutherland mines the same bed near the village, and delivers his
