584 GEOLOGY OF OHIO. 
one of which is supposed to be No. 6, and the other the next bed above. 
In a run near the road in this vicinity, an imperfect section was obtained, 
showing the blue limestone at bottom three feet thick, and thirty feet 
above it the bottom of a bed of massive sandstone full fifty feet thick, 
with signs of coal six feet below it, with shale between the coal and sand- 
stone. Near the summit, about seventy feet above the top of the sand- 
stone, 1s the outcrop of the uppermost bed. On the next road to the south 
of this, a mile anda half west from Roscoe, the upper part of the great — 
sandstone bed below coal No. 6, forms the pavement of the road, and be- 
neath is a cave formed by the overhanging rock and extending entirely 
across under the road. The bottom of the sandstone is fifty-five feet below 
the road, and down the run fifteen feet lower is a fine exposure of the 
gray limestone two or three feet thick, with an inferior kind of cannel 
coal under it. A blue limestone crops out still further down the run, 
only about twenty feet under the gray limestone—shales and slaty sand- 
stones occupying the intermediate space. The hillsin this part of the 
township are quite high enough to catch No. 6 coal, and also the next. 
bed in many localities. But No. 6 is the only bed known in the town- 
ship as of much importance. It is opened at a number of places to the 
south of Roscoe, as at Dougherty’s, Oder’s, Jacob Housers, ete. The bed 
is from three to four feet thick, the coal is in good repute, and that from 
Oder’s bank is hauled to Moscow, in Virginia township, for blacksmiths’ 
use. But the most important mines in the township are in the south- 
east part, near the line of Virginia, especially those worked on adjoining 
tracts, belonging respectively to the Coalport Coal Company, and the 
Summit Coal Company, both under the management of Mr. Jos. Alexan- 
der. The locality is a mile and a half from the canal, with which it is 
connected by a horse track railroad. The coal bed is three feet ten inches 
thick, with a seam of shale one to two inches thick, fifteen inches above 
the floor. The mines have been in operation fifteen years. They now 
employ about twenty men, and the coal, which is of good quality and in 
good demand, finds a market in the central part of the State, being trans- 
ported west by the canal. The roof of the bed is blue shale, and in the 
shale beds above and below the coal, kidney ore is found, which Mr. Alex- 
ander supposes will prove sufficiently abundant to work. He finds the 
dip to be southeast sixteen and one-half feet in a mile. 
Prosser’s coal mine is three miles south from Coshocton, and half a 
mile west from the canal. The bed is cloge upon four feet thick ; contains. 
no visible sulphur but what can be easily sorted out. The upper part is 
harder coal than the lower, and separated from it by a small seam of fire- 
cley,eighteen inches above the floor. It has been worked for three years
