Lesley. I ^^ [Jan. 2 and Feb. 6, 



Warrior's Run ; and along side of one of the summit cuts of the railroad. 

 Grood wash and lump ore show in the walls. No sandy ore is seen. The 

 R. R.cut shows 10 feet of wash ore for a length of 100 yards. Altogether 

 we have here say, 40,000 cubic yards of ore in sight. 



No. 21. Wrye Bank. The local map, fig. 33, shows this extensive group 

 of shafts commencing 450 yards northwest of the railway track, at an eleva- 

 tion of 40 feet above it, and continuing along the road up the slope to an 

 elevation of 100 feet above the R. R., a distance of 400 yards. Over most 

 of this surface the show amounts to little, proving how little we can rely on 

 the surface indications as negative testimony. For, these works were ex- 

 tensively driven from 1852 to 1857, and yielded some very rich ore, while 

 the surface showed only poor sandy ore. 



There is one open cut, 25X20X10=5,000 cubicyards large, showing wash 

 ore in the walls from top to bottom, none of it rich, decidedly sandy, holding 

 ironstained calc. sandstone masses, as at the east Pennington Banks. Very 

 good open ore, bluish, and heavily charged with manganese occupied the 

 west end of this open cut (Rocking). An old miner reports, that in the 

 shafts they went through 26 feet of pretty worthless loose stuff and then 

 worked 18 feet of good lump ore, without getting through ; that the shafts 

 up the hill were dry ; those lower down quickly filled with water, and were 

 therefore abandoned, one after the other, before they could get out more 

 than 10 or 12 feet of lump ore. What the charcoal furnace miners called 

 worthless is now valuable for hot blast, especially anthracite furnaces, and 

 the whole of this great deposit will be washed and sold. The breadth of the 

 belt of shafted ground is about 100 yards, but must be considered as in- 

 definitely greater along the strike. 



I am informed that in these old diggings the body of ore sank to 50 

 feet beneath the surface and thinned away, but came in thick again lower 

 down, and approached the surface. Two good pillars are known to be 

 left standing in the old works, under a top covering of sand, one at the 

 lower end, the other at the upper end of the works. In the last, solid 

 rich rock ore lies 45 feet beneath the surface. All the shafts are now 

 caved in. The ore layers were traced for several hundred yards east- 

 ward by trial shafts. 



The appearance of this ore differs from that of the Pond Bank No. 2 so 

 much that we should suspect them to belong to a different geological hori- 

 zon. This suspicion is almost confirmed by the general southeast dip of 

 the outcropping rocks here and there exposed at the surface. This import- 

 ant structural question is clearly expressed by my Section C D (fig. 3), 

 which passes through these banks. It is quite certain that the rocks which 

 on dissolution delivered these ores, are the mother rocks also of the Kerr 

 and Bredin, Hostler and Pennsylvania Furnace ores to be described here- 

 after. The great breadth of the Dry Hollow Outcrop belt corresponds 

 with that of the localities just named, and I think it pretty evident that 

 we have here two horizons of Lower Silurian ore-bearing limestones 

 close together. 



The old Sandy Bank is a group of small shallow pits, in very sandy
