TUSCARAWAS COUNTY. 07 



nished the greater part of the kidney ore that has been used in Tuscara- 

 was county. No effort has been made to drift for it, and it is doubtful 

 whether the quantity is sufficient to pay for the expense of drifting, but 

 in the valleys, and on the slopes of the hills, it has been largely and 

 profitably mined by stripping. 



Coal No. 5a. 



About Mineral Point a thin seam of impure cannel is found, eighteen 

 to' twenty feet above Coal No. 5. It is of no economic value, but has 

 been opened on the old furnace property at Zoar Station, at Mineral 

 Point, and at the tunnel, where it is cut by the excavation. This is ap- 

 parently a local seam, as I have found no traces of it north or south. It 

 may, perhaps, be identical with some of the coal seams in the southern 

 part of the State. 



Coal No. 6. 



At a variable distance — twenty to fifty feet — above Coal No. 5, lies 

 one of the most important and widespread coals of the Ohio coal basin. 

 This is the "Big Vein" of Columbiana county, the Osnaburg coal of 

 Stark, the Steubenville and Rush Run coals of the Ohio valley, the main 

 seam of Holmes county, and that chiefly mined in Coshocton. It is also 

 identical with the "Great Vein" of Perry county, here assuming its 

 most important development. In Tuscarawas county this coal seam is 

 more exteiisively mined than any other, though in the northern town- 

 ships it, is less thick and valuable than in some of the neighboring coun- 

 ties. 



At the tunnel on the Tuscarawas Branch of the C. and P. Railroad, 

 Coal No. 6 is the " upper tunnel seam," here having a thickness of from 

 three and a half to four feet ; the coal is soft and of rather inferior qual- 

 ity. 



At Mineral Point it has been opened in numerous places, but never 

 worked, being less valuable than the underlying seam. No. 5. On the 

 south side of Huff's Run it is the coal mined by John Black, three and a 

 half feet thick, and of medium quality. On the old furnace property, 

 in Fairfield, it is four feet thick and quite good. This seam furnished 

 the fuel used for twenty years under the boilers at the furnace. 



At the Goshen salt-well it is the seam which supplies the fuel used in 

 evaporating the brine, and lies one hundred and fifty-five feet aboye the 

 well-head. It is four feet six inches in thickness, with a slaty parting 

 near the middle — a character which marks it over a very large area. Its 

 quality is also typical of the seam — black, rather soft, highly bituminouF, 

 and cementing.
