dip nj most "horizontal. — Top ore bed scarcely 3 or 4 feet under surface any- 

 where ; ore beds thoroughly softened and enriched by dissolution of the 

 shells ; lowest bed very rich ; distance 1,500 yards ; breadth from brook 

 up to hilltop 200 yards ; total amount of soft ore above brook to be got 

 by stripping, 400,000 tons ; total of ore to be got by stripping or other- 

 wise, 060,000 tons. 



Note.— The deduction 660,000 to 400,000 is based on tbe fact that 

 towards the bottom of the slope the covering shales get to be 10 or 12 

 feet thick (as in the old celler opposite Walter's house), and may be 

 equally thick in other places. This will interfere only with tl.e open 

 quarry work, but not with underground mining. 



(d.) South of the brook the beds descend beneath the country very flat 

 and are softened doubtless to a great distance downward. If we assume 

 800 yards, we have thus, beneath water level, one million (1,000,000) tons 

 of soft ore. 



(e.) From Walter's eastward. — For the first 1.300 yards north eastward. 

 At 800 yards the crop has got down 25 feet below the crest of the ridge 

 on its north face ; at 1,300 yards 100 feet. Most of the distance, the 

 covering rocks allow the complete sofening of the beds. Mining from 

 the brook by a short tunnel (northward). Breast of say 200 yards. Total 

 of soft ore, 580,000 tons. 



Below brook water level ^in the other direction, southwards and down- 

 wards) another 580,000 tons of soft ore, or even a larger quantity, is 

 available. 



(/.) Along the crop, in the curving valley bottom of the (northern 

 brook (north of the ridge and against the mountain), 2,800 yards to the 

 end of Dutch Corner. Ore all below water level. Dip steep towaids the 

 east end. Extent of softening say 40 yards down. Total of soft ore, 

 250,000 tons. 

 Soft ore above water level, one million one hundred and twenty 



thousand tons 1,120,000 



Soft ore below level, one million six hundred thousand tons. . . .1,600,0C0 



Soft ore parts of the bed only 2,720,000 



It is unnecessary to calculate the quantities of harder ore in the unde- 

 composed parts of the beds, amounting to millions of tons, for these will 

 remain as a reserve for the future. The regularity of this ore formation 

 enables one to assert that there lie six million (6,000,030) tons of ore, 

 more or less, under every square mile of the district, where the dip is 

 gentle. 



Xo account is here taken of the ten miles of vertical beds from Dutch 

 Corner to Bedford, and the vertical run of the beds for some miles north 

 of St. Clairsville along the west side of Dunning*s Mountain, towards 

 Sarah Furnace, on the way to McKee's Gap. 



A railway line up Dunning's Creek from Bedford to Holidaysburg (or 

 McKee's Gap) will bring into play this long outcrop (north of St. Clairs-
