122 F³. furnished some little hard ore from the same bed, but has not been recently worked.

The Bloomsburg red shale occupies the center line of this basin all through Lewis township, but is eroded soon after entering Hartley by the coalescing of the two Ore sandstone outcrops, as already mentioned.

The Ore sandstone south of this basin folds over the Paddy’s mountain anticlinal, the axis line passing a little north of the Pleasant Grove Evangelical church, with dips of about 10° in the Clinton shales underlying the ore group. On the road from S. Yohn’s saw mill to Mifflin- burg and on the crest of this axis east of Pleasant Grove, E. Orwig has opened a lime quarry in the lower Clinton lime shales, which are said to have furnished some thin but good lime beds. The dip is flat towards the northwest and the quarry and kiln have been abandoned for some time.

The Ore sandstone shows slightly on a south dip of 20°, just before reaching the triangular forks in the road near Hoofnagle’s place, south of which the Bloomsburg red shale makes a distinct band passing into West Buffalo township above the forks of the road at J. Boyer’s and about ¼ of a mile north of the Buffalo creek ridge.

Along the public road south of Pleasant Grove, the Ore sandstone is not exposed; but the underlying brownish shales show near the old burned grist mill on a 30° S. E. dip. Further west and near the school-house, a brownish-gray sandstone crops upon a 25° dip, possibly a representative of the Ore sandstone, which nowhere seems to carry ore on this outcrop.

Entering Hartley township, west of Pleasant Grove, the outcrop is in places somewhat obscure; but seems to be displayed in a long gently curving ridge extending for about 9 miles west in the main Buffalo valley synclinal to within about 3 miles of the Mifflin county line. Here it basins and returns about 2 miles, apparently crossing the railroad east of Weiker station, and after lapping over the White mountain anticlinal makes a synclinal loop between
