found in North Carolina, in Guilford, Cabarrus, and Mecklen-burgh Counties. The fibrous variety has been observed at Silver Hill and at Conrad Hill, in Davidson County, and in a number of other localities in North Carolina, but is rarely of any gem value. In the Torrey Collection at the United States Assay Office, in New York City, are a few fine gem pieces of malachite from the Copper Knob Mine in Ashe County, N. C.
MALACHITE
At Morenci, Ariz., there have been found masses of azurite and malachite resulting from the alteration of azurite. These masses are botryoidal in form, so that if the tops of the spheres are cut across, the two minerals are shown in distinct alternate layers (often two to four layers of each) and bandings, forming most beautiful ornamental stones, which are often from 1 to 6 inches across, and admit of a very high polish, that produces

a novel and pleasing effect. If it were found in sufficient quantity, it would make a valuable ornamental stone. Rus-kin has likened this combination of colors to the " green of the fields and the blue of the sky," and notwithstanding the strong contrast, the blending makes it a harmonious one. The association is entirely new and one of the most beautiful ever found. There is little or no demand for this stone outside of Russia, where clocks, jewel-caskets, mantels, table-tops, and doors are covered with a thin veneer of carefully-pieced mala­chite, cemented on slate or marble, not made of solid blocks as is often supposed.
