Some of these minerals were shown in 1880 to William E. Hidden, a young naturalist then engaged in searching the mineral belts of North and South Carolina and Georgia for rare minerals. The beauty of these specimens led the young enthusiast to make a thorough search for the parent ledge; and, after a few weeks of earnest labor in cutting deep ditches in the soil near the spot where a number of crystals had been found, he was rewarded with the discovery of the original deposit in a rock of gneiss. In this rock, in which felspar preponderates, he found implanted in open pockets and lenticular fissures crystals of emeralds, quartz, rutile, monazite, beryl, and also many crystals of long and slender shapes which appeared to be diopside, but which exhibited colors of white, yellow, and green of the most beautiful emerald hues. The mineral which appeared to be diopside was submitted to the examination of the distinguished chemist, J. Lawrence Smith, who soon pronounced it to be a new form of spodumene, and named it Hiddenite after the young explorer. Since then the explorations have been continued, and have yielded many very beautiful specimens of both the emerald and the hiddenite. At the depth of thirty-three feet below the surface of the rock several pockets were discovered which yielded some beautiful emeralds and hiddenites. They occurred at the bottom of the pockets, just as the finest crystals of tourmaline are found in the cavities of the granite ledges at Mount Mica in Maine. Twelve of these pockets were found within an area of forty feet square, extending to thirty feet in depth. The largest crystal of emerald found was more than three inches in length and three quarters of an inch in breadth, but its color, although of the true emerald hue, is, however, rather faint. Some of the smaller crystals are of much deeper tint, and resemble the pure specimens from Granada. But the most interesting treasures of the mineral kingdom revealed by this exploration were the crystals which analysis proved to be composed of a silicate of alumina and lithia, otherwise known as spodumene. Some of these crystals were white or light yellow, others were of a rich yellow hue shading into brown, while others exhibited the purest prismatic green of various depths of hue. In some of the green crystals the color has been uniform, while in others it is more intense at one end of their extremities. Quite a number of the crystals and their fragments have been cut and polished into gems which rival, by their lustre and beauty of color, the best of the South American emeralds. On account of their extreme rarity, as well as their beauty, they have been sought for by amateurs, and have commanded high prices. As the field of deposit thus far known is quite limited, we fear that the yield of this charming mineral will not meet even the demands of science.
