road leading across the mountain from Belleville to Greenwood furnace, which is further confirmed by a satisfactory exposure of limestone near the western end of this little notch and west of the school-house, which shows a dip of 55° to the southeast. West of this point it seems to be entirely lost in the wide strip of slate outcropping along the base of Stone mountain; or its presence may be obscured by the Stone mountain fault.
The New Lancaster valley anticlinal enters the township along the pike west of Kishacoquillas P. O., and, keeping a southwest course, passes a little north of Yoder’s G. M. and directly through the old Greenwood furnace ore banks. The first exposure of limestone on the pike dips about 35° to the southeast. About 1½ miles west of the Kishacoquillas at the bend of the pike, the axis is well exposed with dips of about 30° in each direction. The limestones are exposed here about 50 yards along the road. They have a gray-blue color; are somewhat siliceous and occur in very thin beds.
The Zook quarry, about 1 mile east of Belleville and close to the north side of the pike, has been sparingly worked to supply the local demand for farm lime. The stone is hard and blue and occurs in thin ribs, none of it very attractive in appearance; but when burned it is said to make an excellent farm lime.
Greenwood ore banks.
In the vicinity of Belleville the dip is northwards at angles of from 15°–20°, declining in strength to about 10° going southward to the anticlinal axis at the old Greenwood ore bank. This old mine was formerly actively worked and a considerable quantity of pipe-ore was conveyed from here across the Stone mountain for mixture with the fossil ore beds mined in the vicinity of Greenwood furnace; but it was abandoned many years ago, partly on account of the cost of mining and partly on account of the exhaustion of the ore. Like similar deposits in the Nittany and Penns valley districts of Centre county, the Belleville ore was found in pockets in the limestone, of varying size and per-
