Rh The beds occur largely in thin seams from a few inches to one foot thick, and weathers into rough irregular masses. It is of good quality, however, and if properly opened at the eastern base of the ridge in the ravine a very excellent and economical quarry could be developed here.

Wagner's quarry joins Dreese immediately on the west, so closely as to make them practically one opening. It is not developed so deeply, but by nearly the same method and in the same measures. About 60′ down the south slope of the hill nearly 40′ of lower beds are exposed, somewhat shaly and showing the presence of the “soapstone division” mentioned in the openings further east towards the Susquehanna, so that the lower Bossardville beds of No. VI maintain their thickness of 100′ to 125′ in this part of the field. Few openings have been made in the high synclinal knob to the west of the Wagner quarry, where the dips must be rather severe and there are few natural advantages for opening.

D. Bauch has a small quarry about 100 yards east of the road between Beavertown and Troxelville, and about half way up the south flank of the ridge. Going north through the gap of Mill run the limestone ridge is seen to be doubled, being divided into two separate ridges opposite the bridge over the stream. Down the creek the side hill has been quarried for gravel for road purposes and shows slate, limestone and loose chert with un average dip of about 60° S. E. in the north leg of the synclinal. This dip is quickly reversed, for just before reaching the forks of the run the Oriskany flinty sandstone outcrops on a 30° N. W. dip. There are no additional openings west to the Spring township line except perhaps to make mention of a small hole on the west side of Mill run, where some few feet of limestone are exposed, dipping 30° N. W. There is not in the whole township a single good quarry and but little first-class stone has been developed in any of the small openings visited, despite the fact that the ridge is everywhere close to the railroad, and is twice completely gapped by Middle creek and Mill run, in which gaps excellent quarries could be opened.
