other on a second north dip of 50°. The former of these two had been developed for 20 yards and considerably stoped in both directions from the basin.
The sandstone bed before mentioned lies to the south of this opening, thin, but making a distinct ridge north of White mountain. About 10 yards south and back of this sandstone bed the lower ore-bed (Black Fossil?) is opened about 20′ above water level carrying 12″ to 18″ of ore between the slate roof and floor, driven in for 30 yards and stoped to daylight. It was impossible to secure any samples of this ore which would have shown the characteristic marks, and its horizon is, therefore, only a suggested one.
The railroad cut, just south of this opening, shows a splendid exposure of sandstone and shale 60 thick on a northward dip of 20°, red at the bottom and gray on top, evidently a portion of the white Medina sandstone No. IVc. The proximity of this rock to the ore-bed seems to confirm the correctness of its being placed near the bottom of the Clinton series.
Zimmerman’s old mine (now owned by D. C. Johnson), is situated about 1½ miles below Cherry run, and is opened on the south side of the railroad on a steep northwest pitch and a short distance from Kaylor station. This bed is called the Bird’s Eye fossil, and probably correctly so, as it is quite fossiliferous and is evidently low down in the Clinton series. It is from 12″ to 14″ thick, with a yellow shale roof and floor. About 100 tons have been mined, yielding about a 45 per cent. ore. The tunnel across the measures to the bed is about 100′ long, and the breast about 30′ high.
A tramway has recently been run west from the original opening towards the point of the hill, where a new cross-cut, 30′ long, through the same measures, strikes the ore bed, 10″–12″ thick, at a somewhat lower level and on a dip of N. 25° W. 45° between gray slate walls. The ore is here largely hard fossil; but softer towards the outcrop, and has perhaps 60 yards of breast. There is a thin sandstone underlying the ore bed at a vertical distance of about 150′, locally called the “blue rock” but probably a representa-
