212 F³. side of which, dipping only 10° or 15° and containing good beds, was not being developed. The northwest dip on the north side of this arch amounted to 50°; but is only local and displays a very ordinary stone spoiled by cleavage.

Nos. 4 and 5 make one opening, 100′ long, exposing only outcrop stone and as yet undeveloped and of no commercial value. Both quarries have been abandoned.

Nos. 6 and 7 also make one quarry, 100′ long, and sparingly developed in practically the same beds.

No. 6. Reichenbach’s quarry was actively developing beds dipping northwest about 50°, extending the anticlinal roll before mentioned. Only about 100′ of limestone have been uncovered, although the face of the quarry has been cleaned to the heighthheight [sic] of 20′.

No. 8 is a small hole next west, showing about 15′ of stone on the northwest dip, cut up with cleavage and of poor quality yet.

No. 10. Some little distance west there is a quarry about 350′ long, six lots of which are owned by S. and H. Bickhart, one lot on the east end now being owned by them. It makes decidedly the largest and best quarry in the group. The general dip is still northwest; but the anticlinal can be seen forming at the west end of the exposure, where some excellent blue stone was being obtained.

None of these quarries will get good working beds, until they have blasted through this comb and entered the hill on the regular southeast dip, where the beds are free from the cleavage exhibited along the crown of the arch, and for some reason appear to be more smooth-grained and regular than the same beds on a northwest dip. The bed, however, will soon take cover on the south dip, necessitating stripping; and it was to avoid this expense no doubt that developments have been confined to the outcrop.

Henry Mengle had two kilns and a quarry in operation lower down the flank of the ridge, upon the final southeast outcrop of the beds, where one or two good beds aggregating 15′ in thickness have been developed for a considerable length, but limited depth.
