about 2 miles north of Freeburg, and an analysis of the soft ore yielded (See Report F, p. 27).

Iron, 50.500
Sulphur, .024
Phosphorus, .257
Insoluble residue, 15.220

A short distance (500 yards) further south the bed is again opened on the south dip but not now worked. An old drift had been opened close to the public road on an increased dip of 10° southward.

Information obtained after the examination of this field from Messrs. P. & W. Bickel at Freeburg put the output of their mines at about 100 tons a month from four active drifts, most of which was sent to C. L. Bailey & Co., Harrisburg. Ore dressere are largely required, and the ore was hauled to Kremer, Station 1½ miles, at a regular contract price of 40 cents per ton.

F. C. Moyer’s opening is still further south and nearer Freeburg, on the west side of the public road, and is said to have been developed on the block ore bed. The drift was entirely fallen shut and nothing could be seen of the ore or accompanying rocks; but the opening is certainly north of the Ore sandstone ridge and in measures too low for the Danville fossil beds.

The Bloomsburg red shale shows crossing the Freeburg road south of the cemetery, spreading over a wide belt on a dip of about 20° southward. On the road leading east from here to the red brick school house in Penns township on Middle creek, the Clinton olive shales, with some red bands, outcrop on a general dip of S. 10° E. 25°. The Ore sandstone is also exposed just near the turn of the road northwards on a dip of S. 20° E. 12°, rising northward along the ravine to arch over the Shade mountain anticlinal, and showing one massive ledge of grey-brown sandstone, 6′–8′ thick, underlaid with shale.

Neither of the ore beds associated with this rock seem to exist in workable conditions at this point. The underlying lower Clinton shales show further north on the crest of the anticlinal with 10° dips; but neither the block ore nor the Bird’s Eye fossil ore bed extends this far east.
