By rail-road it is about 10-11 miles from Stonewall to Cherry Run and while here there is no Cretany yet the entire Heldenbergian is at the latter place present all of which must have been present at Stonewall for the sea came from the north and yet all of it is absent at Stonewall. Of course in different places there is probably once in less of it preserved. In the first quarry operated by the Pennsylv- niania Glass sand Co which is high up on the mountain side, at least 100 feet I'm probably 75 feet wide and 100 feet deep one is im- pressed by the purity of the sand in spite of its many faults, and the wicker-like nature of it. This only the loose soft material that is used as the hardened layers have too much iron. About one third of the material is thrown away, the remainder is crushed, screened and altered to be used for glass sand. This also pulverized and used in roof making and by potters for glaze. About 120 tons of material is quarried per day and the sand for glass making is sold at about # 1.50 per ton. The Cretany sandstone at this locality is an unmitatable clearly worked hard sand.
