TUSCAEAWAS COUNTY. 71 



hand and Columbus and Cincinnati on the other; but it is evident that 

 toward the East the demand for coal will be fully supplied from Steuben- 

 ville, Connellsville, and Pittsburgh, while between Tuscarawas county 

 and the markets of the West the production of the Coshocton, Cambridge, 

 and Perry county mines will be interposed. Hence, the natural outlet 

 for the fuel of Tuscarawas county is plainly in the direction of the great 

 coal-less region bordering the lakes. Already several lines of transporta- 

 tion have been opened to Lake Erie, and it only remains to be shown 

 that an abundant supply of good fuel can be procured in Tuscarawas 

 county to prove that this will be the theater of great mining and manu- 

 facturing enterprises. 



Mahoning Sandstone and Coal No. 6a. 



Above Coal No. 6 we find in Tuscarawas county a mass of strata about 

 one hundred feet in thickness, which usually contains little that has 

 economic value. Immediately over the coal is a stratum of black or gray 

 shale of variable thickness, and above this, generally, though not always, 

 a massive sandstone, the equivalent of what is called in the eastern 

 counties of Ohio and the western of Pennsylvania, the Mahoning sand- 

 stone. This varies in thickness from nothing to nearly one hundred feet, 

 is usually coarse, and very frequently is in part a fine conglomerate, in 

 which the pebbles range in size from that of a grain of wheat to a bean. 



The sandstone is well shown in the hill above ,the tunnel on the Tus- 

 carawas Branch Railroad, and on both sides of the valley of the Tusca- 

 rawas from Zoar to Dover. Its conglomerate character is conspicuously 

 developed on the west side of the Tuscarawas below Zoar, where masses 

 of the rock have fallen down from the hills into the road. 



In places this sandstone comes down to, and even cuts out, Coal No. 6. 

 In the hills south of HufE's Eun, below Mineral Point, it rests upon the 

 coal, and, as usual in such cases, this is thinned and deteriorated by it. 

 Below Zoar Station for some distance along the river, Coal No. 6 seems to 

 be entirely cut away by the sandstone, but about the Goshen salt-well it 

 comes in again in full force, and the sandstone thins out and almost dis- 

 appears. Passing southward along the valley of the Tuscarawas, the 

 Mahoning sandstone is visible at intervals all the way to the Coshocton 

 line, but in many places it is wanting, being replaced by shale'. The 

 changes which occur at this horizon are well shown on the two sides of 

 the Stillwater Valley at Uhrichsville. In the hill south of Dennison, 

 Which rises to the height of three hu,ndred and fifty feet, no heavy bed of 

 sandstone is seen, almost the entire mass being composed of shale; while
