Rh entries about 4′ of slate additionally have to be removed for a traveling way.

The ore is all hauled in wagons to Patterson station on the Pennsylvania railroad, opposite Mifflintown, costing, during the season of 1888, 75 cents a ton for haulage. With the cost of mining and royalty added, the ore cannot cost much less than $2.50 on the cars at this point. The Duncannon Iron Co. has used about 150 tons a month in their furnace during the last 16 years, where its yield has been found to be about 33 per cent. of metallic iron.

On the J. Suloff property, about one-half mile further west, the “back vein” was, at one time, leased and mined by Messrs. Williams and Willis. This drift has been idle for some time and it was reported that it had been extended northwards for some 200 yards beyond or back of the ore bed towards the mountain, with the hope of getting to an outcrop of the “mountain vein.” Whether the intention was to develop the Danville fossil ore bed, which occurs slightly lower down in the Clinton measures and nearer the mountain, and has been worked at the Glamorgan mines on the west; or, whether a knowledge of the duplication of the ore outcrops at the Duncannon mines, led to the supposition that a drift at this point should necessarily develop two beds, there are no means of knowing. The latter object does not seem possible to attain if the structure has been properly made out; and the other hope of striking the Danville fossil ore is wholly dependent upon its extension as ore this far east of the Glamorgan mine. But even if this hope was realized, and the bed found to exist in good condition, its dip at this point would be rather severe, and as it is only about 9 inches thick at the Glamorgan mines it would be extremely doubtful whether it could be very advantageously worked under the different structural circumstances.

The Glamorgan or Graham mines which operated both outcrops in the synclinal are located about midway between J. Suloff’s and the river. The amount of ore mined from
