TUSCARAWAS COUNTY. 67 
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 es been largely and 
profitably mined by stripping. | 
Coat 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. 
Coa 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 extensively 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 above the 
well-head. It is four feet six inches in thickness, with a slaty parting 
near the middle—a character which marks it over avery large area. Its 
quality j is also typical of the seam—black, rather soft, oe, bituminous, 
and cementing.
