770 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 :

1. Coal No. 11, blossom. 



2. Shaly sandstone and small slabs of limestone 60

4. Sandstone and shale 85 



5. Coal 1 6 



6. Shale ■-. 10 



7. CoalNo.8 4 6 



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, Goal No. 8 is worked by Mr. Cope, at whose bank the 

 bed is as follows :

1. Eoofcoal 1 



2. Clay 8 



3. Coal 4 7 



The pyrites band is one foot from the top, and only one- fifth of an inch 

 thick. There are no well-defined partings. The coal is very good. Near 

 Wood's Mills, we find Mr. N. R. "Wood's opening, which shows —

1. Eoofcoal 1 



2. Clay 1 



3. Coal 4 7 



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
