Mining map of Cornwall.
525 Arkansas Mining Company —Producer.
Sample of Arkansas lead ore in a lump as cut frombetween the solid walls of a vein, measuring 24 by 20inches, and 9 inches thick. Its weight is nearly 11 cwt.It contains also copper and iron ore, and the sulphuretof zinc, and is coated over with quartz mixed withbarytes.
522 Forbes, A. C., 12 Old Burlington Street — Producer.
Two specimens of Cinnabar , from the mines of New
Almaden, in Upper California ; one of 14lb. loz., the otherof 131b. 2oz. On analysis by Dr. Hoffman, they are foundto consist of:—Mercmy, 67*25; Sulphur, 10*33; Inso-luble matter, 22*55. The insoluble matter consistingchiefly of silica, alumina, and traces of iron. On distil-lation with lime, 3,750 grains yielded 2,625 grains ofmercury, or 70 per cent.
The mine has been worked one year; and in the monthof November 1850, it yielded 127,500 lbs. of pure mercury.This is exported from San Francisco to the ports of Span-ish America.
[Cinnabar is the only important ore of mercury, but isfound in several states, sometimes in crystals, in lami-nated and granular masses, in a fibrous condition, andmixed with bitumen to the extent of 6 or 8 per cent. Itis soft: Specific gravity =8*1 when pure, and is a sulphu-ret of mercury (Hg. S.). The mines of Almaden, in Spain ,and Idria, in Carintliia, are those from which the chiefsupply has hitherto been obtained; but the discovery ofmercury in the mountains on the coast of California ,some years since, promises to affect the supply very consi-derably, when sufficient means are employed to work themines extensively.—D. T. A.]
523 Davies & Taylor, Abenjstwith — Producers.
Specimens of lead ores.
[The Cardiganshire mines were worked at a very earlyperiod, probably by the Romans. Henry VII . encouragedmining by several grants, involving privileges to thosewho would work these mines. In the reign of QueenElizabeth, there was a grant made of all these mines toThomas Thurland and Daniel Houghsetter, Germans ,who worked them for some time. They eventuallypassed into the hands of Sir Hugh Middleton, whorealized a large profit by working them.
The present value of the Cardiganshire mines will beseen by the following list of their produce:—
