COSHOCTON COUNTY. 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. It should be looked for in the deep runs below Tiverton Centre, 

 and on the slope of the steep hill down to the Mohican. 



Monroe. — The coal seams of this township have been developed but 

 little more than those of Tiverton. T|iere 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 

 gray 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 

 Waveriy 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
