situated bank, near Huntingdon Furnace, a vein of good, red-short ore 

 was struck, and abandoned on account of water. On working one part 

 of this pit the ore became too sulphureous to use. It will be again re- 

 ferred to after describing Bank No. 29. 



The belt of Cale Hollow Ores may be traced northeastward with the 

 same general character. 



Little Bank, for instance, lies two-thirds of a mile northeast (near 

 the Warrior Mark Pennsylvania Furnace Eoad), If miles west of Penn- 

 sylvania Furnace. Here very rich top-washings cover a high flat 

 area connected with Hickory Ridge. Seams of the ore penetrated the 

 limestone rocks all the way down a 40 feet shaft, under which the main 

 body of ore dips northward. 



The Eyer Bank (already mentioned) is an old excavation one mile 

 still further east, on the east side of Half-Moon Run. 



Going on northeastward across a dividing ridge, the ore appears again 

 along Tadpole Run, in Sleepy Hollow, and at the head of the Beaver- 

 dams, for a distance of more than a mile. Years ago, some pipe-ore was 

 raised, for Centre Furnace, east of B. Crane's, but the surface was merely 

 scratched. At the Pennsylvania Furnace old surface-pits, sunk at the 

 beaver-dams, the body of ore probably lies under the bed of the run and 

 would require heavy pumping. 



The "dry hollow " which carries the Valley of Tadpole Run on in a 

 straight line northeastward, and is a geological prolongation of Cale 

 Hollow shows plenty of out-croppings of ore, just as Cale Hollow 

 does, and the ore is of the same kind — pipe-ore. In fact the ore 

 belt continues to McAllister's and the School House cross-roads, eight 

 miles northeast of the Hostler Bank, and far beyond the limits of my 

 large map. 



Between McAllister's and Pinegrove Mills, the country spreads out into 

 a plateau two or three miles wide, through which runs the Brush Valley 

 Anticlinal. Here, far beyond the east limit of my map, are the 



Old Weaver Banks; two open-cuts and several shafts near 

 them, abandoned years ago. No systematic mining was attempted in 

 that early day, the work being done by the farmers. Tradition speaks 

 of "ore veins" being reached, but probably too well watered for the 

 natives to cope with them. "The ore lying around the holes is not a 

 regular pipe-ore, but is mixed with liver-colored ore, and reported red- 

 short." We have here, then, ores not belonging to the Hostler and Penn- 

 sylvania Pipe-Ore Bank system connected with the sandstones of the 

 anticlinal, that is, ores belonging to the under-lying limestone.

 (58) years Pennsylvania Furnace has been supplied with its stock from 

 the extensive excavations on the gently-sloping south side of the anti-
