THE WrInpsor MINE. 
This mine is also situated in Section 1, Tuscarawas township, in 
the S. W. 4. Itisasma!l mine, connecting by a narrow gauge track 
with Massillon. It holds a part of the basin, just described, and, in 
fact, it is worked through into the Sippo mine, getting its ventilation 
by means of the furnace, and its drainage by means of the pumps of 
the latter mine. It produces 40 to 50 tons per day, but has only a 
small territory on which to work. 
THE GROVE Ming, No. 2. 
This mine is located in Section 24, Tuscarawas township, which 
adjoins Section 19, Perry township, in which the abandoned mine, 
Grove No. 1, is located. The two mines are separated by a broad 
‘horseback ” of sandstone. 
There are over 600 acres under lease by this corporation, but the 
coal is already almost exhausted. Only pillar coal is now produced by 
No. 2, and this at less than 200 tons per day. 
The mine is entered by a shaft 140 feet deep. It strikes the 
summit of the basin, from which fact the drainage is complicated. 
Branch pipes must be carried forward to all the workings from the 
pumps at base of shaft. 
The coal is not worked below 2’ 9”, asa rule. Its greatest thick- 
ness is 5 feet. Where horsebacks occur, they generally cut out the coal 
altogether, instead of merely reducing its thickness. The roof is 
excellent, consisting of 6 to 20 inches of black slate, covered by a 
gray sandrock. Bone coal occurs at the top of the seam, and makes 
some trouble for miner and operator. Nodules of ore are frequently
