next west, where a considerable body of ore is still reported to exist.

Reed’s property has been excavated eastward to the line of the Walker property. During the season of 1888 about 75 to 100 tons of ore a month was being produced in this vicinity and shipped to Union furnace at a contract price of $1.10 a ton, delivered at the month of the drift, and as a dollar a ton was paid to haul it for 9½ miles to the furnace this ore could not have been laid down in the stock pile at that point for less than $2.25.

In traveling southwest across East Buffalo township from Lewisburg the Lower Helderberg limestones are first passed over, although these rocks are so largely eroded as to create no hill at this point. The upper Salina lime shales succeed, showing dips of 20°-25° N. W. in the vicinity of school house No. 5, and then a broad belt of the Bloomsburg shales lapping over the Montour axis with dips of from 10°-15° N. and S.

These latter rocks are exposed also along the river road in an old road quarry, dipping N. W. 20° and are succeeded further south at Penny’s house by a flat anticlinal of upper Clinton shales, perhaps 200′ thick, and excellently exposed in the cuts of the Philadelphia and Reading railroad. Further south the dips flatten greatly in the succeeding Mifflinburg synclinal, and after a dip of 20° to the north west are again repeated by a gentle local anticlinal, north of Turtle creek on dips of 10° and 15°.

Limestone quarries.

The structure all through here is rather wavy, due to the overlapping of the Montour and Jack’s mountain axes.

In Buffalo township are several openings in the Lower Helderberg limestone, occurring in the south flank of the limestone ridge west of Lewisburg.

These in order westward are the quarries of Messrs. Gepheart (erroneously printed Gephew on map); Cameron, or Duck; Wolfe; Wolfe No. 2; and on the western point of the ridge along Buffalo creek, Beaver’s or Miller's quarry. None of these openings were very actively worked in the
