190 F³. northern outcrop on property of Mr. D. Hassinger, but the quarry could not be located and was only worked for local farm use.

On the south outcrop, just after crossing the Spring township line, there is a series of openings about three-quarters way up the flank of the ridge whose product is all hauled out on the north side of the ridge for fertilizing the slate farms along Middle creek. There was no work being done here when visited and it was almost impossible to find out the ownership of these quarries, although the names of Messrs. Ulsh, Grick, Goss and Harbster were mentioned as four operators.

The first quarry on the east is about 50′ long and 20′ deep and exposes about 20′ of light gray-blue limestone near the very top of the massive portion of the formation. The quarry was in wretched condition, grass grown and apparently abandoned. The stone was very much weathered and rather siliceous.

Quarry No. 2, next west, was in even worse condition and developed the same strata. Quarry No. 3 was about 30′ wide and showed about 15′ of fair stone, which had been ruinously developed in spots.

Quarry No. 4 was in better condition than any of the others. It was about 50′ long, showing about 40′ of stone, half of which in the center are thin but good dark blue beds, with a somewhat twisted stratification. The quarry, however, has been worked very unevenly, which indeed is true of all the others, where development seems to have been made upon the first fairly good beds met with after crossing the summit of the ridge, so as to avoid as far as possible the adverse haul that would be necessary in carrying away the products of lower and better beds. There are three more small openings still further west, all of which have practically reached the limit of economical development on the beds which they have exposed.

Paul Haines’ property shows a small quarry opened near creek level a little west of the last openings and opposite the railroad station at Robb’s mills. Tt shows about 15′–20′ of white limestone dipping 25°–30°, N. W., which
