actively worked at that time the opportunity for an investigation was much superior.
The upper Salina rocks have a considerable breadth in this township, outcropping between a low ridge of the lower Salina or Bloomsburg red shale on the south, and the Lower Helderberg limestone ridge on the north, A small anticlinal issuing between the two limestone knobs along the Franklin township line reaches the main valley road near the school house 2 miles east of Beavertown, carrying the upper Salina lime shales on its crest, which here show several good but thin beds of limestone dipping about 20° each way. This axis extends west to a little north of Beavertown, where some thin red beds are mixed with the gray limy ones and dip southwards at angles of 60°. A short distance west. however, after crossing Mill creek, the axis dies away rapidly before reaching the Spring township line.
The Lower Helderberg limestone is not well exposed between Middle creek and the Franklin township line, although it makes quite a distinct ridge and the few outcrops seen dip northwards at angles of about 25°. A small quarry shows on the east side of the ravine close to the Franklin line, probably on property of I. Klose. The section exposed, however, is thin and the stone poor. Further north the Oriskany sandstone No. VII is exposed on a similar dip about 30′ to 35′ thick, the stream falling over it as it descends towards Middle creek.
G. Dreese, Jr., has opened a small quarry on the east side of the public road leading to Port Ann, just south of the bridge over Middle creek. About 25′ or 30′ of stone is exposed here on a 30° N. W. dip, sparingly developed as yet.
G. Dreese, Sr., has a larger opening higher in the ridge immediately west of the last, the opening running up to the backbone of the ridge for perhaps 40′ in elevation and 125′ long. The dip is N. 10° W. 50° in a rock section about 40′ thick, mostly in the upper part of No. VI. The quarry was ruinously opened and all the stone developed shows want of experience and good judgment in the opening made.
