summer of 1888, and it was with difficulty that any information could be obtained concerning the markets or the general commercial characteristics of the stone; but they are evidently mainly worked for local farm use and plaster lime.

J. Wolfe’s No. 1 quarry, on the south side of the hill, is about 250 yards north of the pike and near the crest of the ridge. It has been mainly worked to produce farm lime, which is burned in two kilns. The dip is gentle, not over 20° N. 5° W., and upon this dip the quarry exposure, which is about 50′ square, shows about 60′ of rock, capped with shaly fossiliferous beds, not worked. There is one good massive blue bed in the north face of the quarry, from 12′-15′ thick, separated by about 15′ of small one foot beds from a lower deep blue bed of excellent quality, about 6′ thick, smooth grained and very free from siliceous matter. These two beds are chiefly worked here; the underlying beds exposed are all shaly and are not burned.

Martin Wolf’s quarry is about ¼ of a mile east and differs in no essential points from the one just described, except for a slightly steeper dip.

The Cameron quarry (now Packer) is about ¼ of a mile east and was being actively worked during the summer of 1888. All kinds of lime are made here upon demand, and the average output is from 6 to 7 thousand bushels of burned lime per month.

The quarry is opened geologically and topographically like the others in this hill, and exposes a rock section, 50′± thick, dipping 25° N. W. The upper 25′ is shaly and white, and is rarely used. Beneath this there is a good 10′ blue bed separated by about 6′ of shaly beds from a lower 6′ blue bed, corresponding to the two main beds of the other quarries and apparently associated with the Bossardville horizon described in G7, embracing the counties on the east side of the Susquehanna river.

The quarry is about 150′ long, but narrow, and most of the information regarding markets and use of lime was withheld.

Gepheart’s quarry is next east, separated by a small
