good ore at the Furnace itself. Pits of standing water show 20 feet of 

 wash ore in their walls. 



This completes my sketch of this "dry hollow" outcrop east of Half 

 Moon Run. It is a dry hollow because the whole limestone underground is 

 cavernous, and water springs up abundantly in every excavation, but 

 does not flow over the surface. This is a prime factor in the problem of 

 he genesis of these ores, and must be taken into consideration in all 

 speculations respecting the depths to which the brown hematite ores 

 descend in a minable form. 



The outcrop belt of surface wash ore and regular rock ores in which 

 the Hannah Fvu-nace, Bull, Pond, Red and California Banks are excavated, 

 passes on north-eastward into the untried wilderness of the Barrens, 

 where we find upon it the Floyd Bank, an open cut on highland ; ore 

 very sandy for charcoal furnace use, but good and abundant for hot blast 

 coke or anthracite ; and good charcoal ore could be selected from it 

 still. 



No. 18. Reider's Bank, half mile east of Gatesburg, is a small sur- 

 face opening of 30X20X5 = BOOO cubic yards extent. On trial at Cen- 

 tre and Hannah Furnaces it was refused. The surface of the broad 

 low hill north of the village is a sheet of wash ore. The roads north to 

 Stormstown and west to Warrior Mark expose ore ground at the surface, 

 on the slopes of the dry hollow in which the village stands, and to the 

 north and south of the village. The old opening on the roadside 250 

 yards south of the village, is entirely filled up. Considerable quantities 

 of very rich lump ore were taken out here many years ago, mostly from 

 underground galleries. Much ore ground occupies the surface for more 

 than 100 yards north-eastward. Limestone crops out 300 yards west 

 of it dipping S. 30^ E. > 20°, and 300 yards north of it dipping S. 30OE 

 >18o.* 



No. 19, Whorrel Bank, (see Local Map, fig. 17,) is a continuation 

 south-west across Half Moon Run of the Gatesburg outcrop, which is here 

 nearly 500 yards bx'oad. The open cut on the noi'th side of the Gates- 

 burg road is about 40X13X5 = 2600 cubic yards ; that on the south side 

 30X20X3 => 1800 cubic yards. Both have standing water in the botlom, 

 and wash ore in the walls, while very heavy outcrops appear along the 

 road, as well as along the cross-road leading up the ridge north to Love- 

 town, beyond which an old shaft has struck the underlying sand 

 rocks. 



The double excavation in fig. 10, 110X40X7 = 30,800 cubic yards large, 

 is separated by a stratum of limestone dipping S. 30OE.,>26O, (one expo- 

 sure looking like>50O,) the ore underlying, overlying and surrounding 

 one end of it. The wash ore in the sidewalls does not look rich. It is 

 reported that these holes were dry 40 feet deep and yielded good ore. 



* The horizon of this and the Whorrel bank is still higher in the series than the last, 

 as Section O D (fig. 3) will make evident.
