stone hematites, or magnetic ores. The iron made is of the finest qual- 

 ity, and when made into blooms at the forge attached to the furnace 

 commands the highest market price. During the war the metal was 

 tested at Knapp's foundry near Pittsburgh, and was found excellent for 

 gun metal. The excavation at the Old Bank shows about 40,000 cubic 

 yards, or 60,000 tons of ore removed. From the long-abandoned pit 

 just east of the bank, the depth of which could not be measured, as the 

 pitwas full of water, some 15,000 to 20,000 cubic yards, or 25,000 to 30,000 

 tons of ore, seem to have been taken out. 



All these openings, from the Red Bank, No. 1, to the Old Bank, No. 5, 

 are on the property of the Carlisle Iron Works, the boundary line of the 

 tract (10,000 acres) being marked on the map. A charcoal furnace, 

 attached to the property, has been running for nearly eighty years, fed 

 by ores from these banks above mentioned, with slight admixture of 

 magnetic or limestone ores. Probably 150,000 tons of this mountain 

 hematite have been mined from their banks for their furnace. 



This furnace property now known as "Carlisle Iron works," and be- 

 longing to C. W. and D. V. Ahl, was formerly owned and for many years 

 worked by Michael Ege. The furnace has been lately extensively im- 

 proved with new hot-blast and blow-house, additional tuyere, increased 

 blast, &c, and the weekly production of metal raised to 45 or 50 tons. 



The power is entirely water, supplied in abundance by Yellow Breeches 

 Creek and a group of powerful springs on the property.

The development at the Old Bank is sufficient to enable estimates to be 

 made of ore in sight along the range. Taking a prism of ore from 

 the Old Bank to the Strickler Bank (No. 5 to No. 6), nearly a mile west, 

 and assuming less than one-half the thickness of ore showing at the Old 

 Rank, 15 instead of 33 yards, we have 1600X15X1=24,000 cubic yards, or
