COSHOCTON COUNTY. =o. 569: 
on the south edge of Monroe township, south-east from Princeton. It is 
very variable in thickness, often being cut out by the sandstone that 
always overlies it. In Mahoning county it is known as the Brier Hill 
coal, and is regarded as the most valuable bed in the State for blast fur- 
naces. Jt should be looked for in the deep runs below Tiverton Centre, 
and on the slope of the steep nill down to the Mohican. 
Monroe.—The coal seams of this township have been developed but: 
little more than those of Tiverton. There is here the same range of the 
Coal Measures, with the addition of one higher coal bed, the outcrop of 
which may be recognized close to the town of Spring Mountain, which 
is on as high land as any in this township. The gray limestone is seen 
about sixty feet lower down, half a mile to the south. The only coal 
mines opened in the township of which we have any knowledge, are 
Cooper’s two mines, north-west from Spring Mountain, and McFarland’s, 
on the south line of the township. Our examinations of these, as of 
most of the other coal beds in the county, were made under very un- 
favorable circumstances. As they are worked only in the winter season, 
the localities are commonly found with difficulty, and when found the 
drifts are’ flooded with water, so that they cannot be entered, and no one 
is about to give any information. The coal extracted is usually all car- 
ried away, not enough being left behind to give one any knowledge of 
its quality. For this reason it has been impossible to furnish specimens. 
of the coals for analysis or the cabinet. 
Cooper’s bed was found in this condition. The coal seam appears. 
to be four feet thick. It is overlaid by a confused mixture of fire-clay, 
shale, and limestone, the last close to the roof, and supposed to be the 
eray limestone. Over these strata, which are sometimes more than ten 
feet thick, are massive sandstone rocks, much tumbled, the bed of which 
is not less than twenty feet thick. The coal has been mined to some ex- 
tent for use of the farmers around. 
McFarland’s coal mine, as already mentioned, is in the lowest bed of 
the series, No.1. It appears to be three feet thick, and is overlaid by 
slaty sandstone, of which eight feet are visible. The coal seems to be 
partly cannel. In the run, about fifteen feet below the opening, are the 
Waverly shales, recognizable by their fossils. 
Clark.—The principal coal mines of this township are in the south-east. 
part, near the line of Bethlehem, on the farms of Thomas Elliott, John 
Moore, and J. Shannon, all in Coal No.6. Jas. C. Endsley’s coal bank, in 
Bethlehem, belongs to the same group, and is the most important one, 
having been worked eighteen years, and supplying a large part of the 
two townships with coal. It is forty feet above the gray limestone, under
