270 F³. seemed of better quality; but for reasons already stated they had not been developed. The quarry is about 100′ long and has been worked for some time. Some of the beds are quite fossiliferous. Burnt lime sold here for farm purposes at 6½ cents per bushel; building lime 15 cents per bushel.

Owen’s quarry, about a mile west of the Juniata Sand Company quarry and just beyond the small anticlinal roll which duplicates the Oriskany and Lewistown formations along the pike the limestone is opened in a small quarry on Owen's property, dipping N. 38° W. 45° and exhibiting a medium quality of stone, poorly exposed. West of the first small stream going towards Strode’s Mill, the limestone is reversed locally with a southeast dip of 60°.

The strip of country immediately south and west of this point through which the dirt road passes is composed of the upper Salina lime shales, furnishing a rich and fertile soil. These same rocks are well exposed along Strode’s Mill run, north of an excellent exposure of the Bloomsburg red shales at the mill dam which dips northwards at angles of about 50°.

Northwards from this point the Salina marls become more and more limy approaching the first synclinal ridge. The lower member of No. VI limestone outcrops with increased dips of fully 80° near the saw mill, where the massive middle members are first well exposed making distinct ledges over which the creek falls to the saw mill. The limestone has been slightly quarried here and shows an excellent series of beds from 4′—8′ thick, and in all about 80′ thick.

Spangler’s quarry.—Along the road from Lewistown to Ferguson valley Jacob Spangler’s limestone quarry is first met with on the south flank of the first ridge: dip about 50° N. W. The quarry is opened in the middle member of the formation, although but a small portion of the series is developed. The stone shows a dark blue color and is of even texture. well suited in every way for both building
