Marion, North Carolina, Colonel Deming has obtained some very good garnets in sufficient quantity to offer them to the trade; also, one fine amethyst of a magnificent purple color and over one inch across, fine aquamarines 1 to 6 carats in weight, and some beautiful chloritic inclusions in quartz, which, when polished, show very fine landscape effects. Among the finds which maybe classed in general as accidental are the following:
Garnet. Of the large garnets from Salida, Colorado, previously referred to, over a ton has been sold during the past year. Quantities of almandite garnet are said to have been found in the gravel of the placer mines near Lewiston, Idaho, in rolled and pitted grains from T^ to h inch across. They would cut into gems and jewels for watches.
Quartz. The large masses of clear quartz referred to in the last report as having been found near Abingdon, Virginia, were in reality found in the mountains of Ashe and Mitchell comities, North Carolina. In addition to these, one large crystal weighing 190 pounds and two smaller ones, weighing 60 and 22 pounds respectively, have been found. Mr. D. A. Jones states thatall these masses were found within a distance of 5 miles the one weighing 22 pounds on the land of Saint Leger Brooks, and the others on the farm of Dr. L. C. Gentry. There was also reported a finding of transparent crystals of quartz, one weighing 642 pounds, another 340 pounds. When these reached New York, however, they proved not to be crystals, but veins of translucent quartzite with crystalline markings of a group rather than of a single crystal, and the clear spaces which were only observed on these crystalline sides would not afford a crystal ball more than one inch in diameter. The larger part was almost white with flaws. Mr. P. A. Hubbard reports finding specimens of rock crystal and rutilated quartz on or near the surface; one mass of the former weighed over 10 pounds and was quite clear, though fractured by frosts. Mr. J. P. M. Butler, of Trinidad, Colorado, reports finding large quantities of crystalline quartz with small doubly terminated crystals of quartz, resembling those from Herkimer county, New York. These may be of value to the dealers selling to Western tourists.
Topaz. In Bulletin No. 27, United States Geological Survey, Prof. F. W. Clark describes topaz, and its alterations, from Stoneham, Maine, and also publishes an analysis of it. A topaz crystal weighing 18^ ounces (587 grams) was found at Cheyenne Mountain, Colorado, about 7 miles southwest of Colorado Springs. It is very perfect, but of little gem value.
Amethyst. Among some amethysts found at Deer Hill, Stow, Maine, during the last year, was one remarkable mass which furnished a gem weighing 25 carats, and of the deep purple color of the Siberian amethyst. Very fair amethysts have also been found at Burrville, Rhode Island.
Jasperized wood. Very little was done during the year 1886 in the development of the jasperized wood deposits of Arizona, but the base of
