erty. Only the sand vein ore-bed has been well developed here about 18 inches thick at the outcrop and 3′ thick in the lower levels. The dip is about 30° and the bed has been worked on this slope for nearly 300′ furnishing a varying amount of soft fossil ore from breasts 50′ to 100′ high according to cover and hard fossil ore in the bottom levels. Eastward this bed has been developed for perhaps one-half mile.
The Ore sandstone is about 35′ thick and quite massive, immediately beneath which is found the “Mud Vein,” 2′ thick, but very lean, and seperated by only 4′ of slate from one of the Danville beds, one foot thick, containing in places a high percentage of iron. Another lower Danville bed has been found in some few places; but always very thin, so that mining has been entirely confined to the sand vein which too becomes nearly worthless by reason of its large percentage of siliceous matter after crossing the river into. Huntingdon county. This bed through the Lucy furnace property occasionally carries a thin seam of slate or Jack near the bottom ; but this is not necessarily characteristic of the bed here. A series of yellow fissile shales underlie the Danville ore bed, and beneath them comes a series of green and red shales and thin sandstones, well exposed near the dam.
Kansas valley and Long Hollow are both composed of the upper Salina marls and lime shales and each makes a very fertile strip of farming land between the two ridges.
On the south side of the township the Ore sandstone and fossil ore beds have not been mined at all, although there are portions of this range which show quite as profuse an outcrop as along the terrace of Jack’s mountain.
On the property of E. Graham, a short distance from Shank’s gap, a number of shafts were sunk at one time upon the Danville ore-beds; but the sand vein was never proven. The Danville beds have yielded some altered fossil-ore along their outcrop from a bed about 2′ thick, overlaid by the Ore sandstone 15′ thick.
On C. Bratton’s land, near the same gap, the same beds have been opened at water level in a ravine where the bed
