TUSCARA.WAS COUNTY. 81 



over it — and which runs all through this portion of the county— has sup- 

 plied a large amount of or6, which has been manufactured at the old 

 Bolivar furnace, or sent to Massillon and Dover. 



On the west side of the river, opposite Zoar, the hills contain Coal Nos. 

 5 and 6, both of about the same thickness— three and a half to four feet — 

 and both having been somewhat worked. Coal No. 5 is of the better 

 quality, and was formerly quite largely mined by Mr. Wm. Medill. In 

 one place it was found folded upon itself, and thickened up, as is de- 

 scribed on another page. 



At Zoar Station we have one of the most comprehensive sections in 

 the county, and one so complete, and so well exposed, that it has been 

 given as a typical illustration of the geological structure. 



Between Zoar Station and Dover there is no marked change in the 

 geology. The hills are capped with the shales of the Barren Measures, 

 containing some valuable deposits of blackband ore, which have already 

 been described. Coal No. 6, partially cut away, and replaced by sand- 

 etone, comes in on the south side, near the Goshen salt-well, and thence 

 extends continuously southward. Coal No. 5 is in this interval appar- 

 ently too thin to be of much value, and the same may be said of Coal 

 No. 4. Between these two seams is a thin seam of cannel, having a 

 thickness of a foot or more, but deserves mention only that it may not 

 mislead the explorer. Along the railroad grade Coal No. 3a is shown at 

 many places, here assuming greater dimensions than any where else in 

 this region, but having little value. 



At Canal Dover the nearest outcrop, of coal is on the west side of Sugar 

 Creek. Coal No. 5 is here three to three and a half feet thick and of 

 good quality. The shales above it are thickly set with nodules of iron ore, 

 as usual, and the deposit has been extensively worked here by stripping. 

 Between Dover and Trenton, Coal No. 6 is mined at frequent intervals 

 on both sides of the valley, and is the chief source of supply of fuel to 

 the inhabitants. 



Between Trenton and the line of Coshocton county, the strata all lie 

 nearly horizontal, and the section of the hills on either side is pretty 

 much the same throughout. Coal No. 4 lies generally a little above or 

 below the bottom lands. Coal No. 5 fifty feet higher up, and generally t«o 

 thin to be of much value. Coal No. 6 is worked almost continuously, of 

 fairly good quality and thickness, but in some places, as at Port Wash- 

 ington, attains unusual dimensions. It is, on the whole, however, infe- 

 rior in quality in this section to what it is either at Coihocton or Urichs- 

 ville. To illustrate the structure of this portion of the valley, the very 

 full section afforded at Port Washington is given in another place.
