deposits of fossil ore, which can be quarried by stripping from four to ten feet of soft slate and soil. The dip of these beds is very light, varying from 5° to 10°; they contain from three to four feet of ore interlaid with slate and sandstone, making a total thickness of six to eight feet, and have the following composition :

Metallic Iron - 31.75
Silica - 8.85
Phosphorus - .37

Although poor in iron the ores contain so large a percentage of lime that a furnace will drive very fast on this stock and make as much iron as if using the 40 per cent. ores. The cost of one ton delivered in Cumberland will be about $3.50, or $10.50 per ton of metal against $9.50 of the 40 per cent, fossil. To partially set off this increased cost there will be a considerable saving of limestone.

The "Big Fossil Vein," also known as the "Levant" or "Block Ore," and found in the Clinton measures, about 1,000 feet below the small fossil just described, and usually within 200 feet of the Medina Sandstone, has not been opened at any point South of Tatesville, in Bedford County, where it is worked by the Kemble Coal and Iron Company.

This ore crops out near the Narrows above Cumberland, and South of the City crosses the Potomac and skirts Knobly mountain, following the course of the Baltimore and Ohio Railroad as far as Keyser City.

Strictly speaking the deposit here assumes the character of a ferruginous sandstone as the following assays demonstrate:
Sample of Top three feet ore, Metallic Iron- .17 06
Sample of Centre four feet ore, Metallic Iron - 18.88, Silica 68.89.
Sample of Bottom three feet ore, Metallic Iron - 18.46

At a point South of Cumberland, surface specimens of the ore assayed 27.77 Iron, 0.33 Phosphorus, and 54.20 Silica. The lower beds are not exposed, but are known to be of superior quality, and will yield about 30 per cent in the furnace; its remarkable thickness and the low cost at which the ore can be quarried and shipped renders it of economical importance. The ore can be laid down in Cumberland inside of $1.80 per ton. A half-and-half mixture of this and the limestone fossil of Bedford will contain 31 per cent, of Metallic Iron, 28 per cent, of Silica, and 36 per cent, of carbonate of lime and other bases. A ton of the mixture costs $2.65, or
