Magic Stones and Electric Gems: Maine

In many graves of the primitive Red-paint People of Maine, small pebbles have been found. As they were not large enough to have served as paint-grinders, and as but one such pebble occurs in any single grave, the presumption is quite strong that they were considered as talismans for the dead. The fact that the practical laborers of our day who dug out these graves instinctively named the pebbles "lucky stones" goes to prove that this supposition is not too far-fetched, although there is no positive evidence to support it. The pebbles were yellow, bright red, or gray in color, the graves explored being at Orland, Maine, as well as at the outlet of Lake Alamoosook, on the south side of this lake and at Passadumkeag; indeed such graves have been met with all the way from the Kennebec Valley eastward to Bar Harbor. The respective symbolic meanings of white and black are illustrated in the designations "white magic" and "black magic," the latter denoting conjurations or spells in which the aid of the powers of darkness, of the Devil and his demons, was sought by the sorcerer, while "white magic" was to be performed by harmless and innocent means, sometimes even by religious rites. In this way it sometimes so closely approached the domain of religious miracle, that it becomes difficult to distinguish between these two conceptions of supernatural action in the material world.

Quartz of a different type with needle-like inclusions is called "Thetis's hair stone." This is a transparent or translucent quartz, but so completely filled with acicular crystals of green actionlite, or occasionally altered actinolite of a yellow-brown or brown color, as to appear almost opaque; seals and charms have been made to a small extent of this variety. Of other inclusions in quartz we may note those of a very brilliant stibnite projecting in all directions, some of the intruded crystals being very curiously bent. Exceedingly beautiful gems have been cut from this material. When this quartz is cut en cabochon across the ravalette inclusions, a cat's-eye effect is produced. The yellow quartz cat's-eye of Ceylon and the green of Haff, Bavaria, are of this type. So densely set were the green actinolite inclusions in the case of a specimen found at Gibsonville, North Carolina, that it was believed by the finder to be an emerald.

An extremely beautiful effect in quartz is produced by enclosed, acicular crystals, or hair-like particles of some other mineral, such as rutile, for instance, and sometimes even of gold. To specimens of this latter type may be referred the Greek name "chrysothrix," used in the Orphic poem "Lithica" and signifying literally "golden hair"; of this the verses tell us there were two varieties, that which may be identified with quartz, having a resemblance to "crystal," while the other, said to have the appearance of chrysoberyl, may have been a yellower variety. To the quartz traversed by filaments of rutile, or the red oxide of titanium, has been given the taking name of "Venus's hair stone"; a pretty French name is Fleches d'Amour or "Cupid's Arrows." The California beaches have furnished some of the most interesting ornamental pebbles, the greater number being of chalcedony or agate weathered from an amygdaloidal rock, while a few are of jasper or fossil coral. Their variegated color-markings made them very attractive ornamental objects in themselves, and there is reason to believe that centuries ago the Indians of this region valued them as talismans or amulets. At present the finest specimens are gathered from Pescadero Beach in San Mateo County, about twenty-four miles west of San Jose, Redondo Beach, fifteen miles south of Los Angeles, and also from Crescent City Beach, in the northern part of California. On Moonstone Beach, Santa Catalina Island, many beautiful quartz and chalcedony nodules have been picked up, which have weathered out of ryolite rock of sanidine feldspar and quartz. It has been quite a custom for guests of the hotels to go down to Redondo Beach and gather these pebbles, and some of those collected by enterprising natives are placed in a bottle of water to bring out the beauty of their colors. Sometimes they are drilled and strung on flexible wire to form long chains or necklaces. Several pebbles presumably from Redondo Beach were found, in 1901, in an Indian grave, where they were probably placed as amulets for the dead.

The occurrence of fluid cavities in quartz, chalcedony, sapphire, and other minerals, is due at times to cavernous structures formed during the growth of these minerals, when the crystalline substances, for some reason, instead of filling these up solid, will avoid the caverns and enclose the liquid of crystallization. In agate inclusions this is found with silicious content, possibly due to the fact that it is to an extent carbonic acid gas, or water containing salt or some other foreign substance. In agate chalcedony, whether in pebbles as minute as a pinhead, or in amygdules several feet across, the liquid is enclosed because the walls of the gaspores in the rock, which are frequently almond-shaped, are gradually becoming smaller, or rather the walls thicken by the deposition of the silica forming agate, chalcedony, or any impenetrable layers, or else an impenetrable form of quartz; then again, frequently toward the centre or when the liquid forms less rapidly, or through some change, the quartz becomes crystalline, either colorless, smoky, or amethystine, and this is due to various inclusions. This gradual thickening of the walls means that the aperture into which the liquid penetrates becomes smaller and smaller until at last it is entirely sealed, so that it becomes enclosed in a kind of nature's water-bottle, these being sometimes as large as in the chalcedony specimens from Uruguay; this is also the case with the hydrolites and the enhydros, when they can be shaken and the water rattles as in a bottle.

An occasional small Redondo Beach, California, or Medford, Oregon pebble contains a moving bubble of air in liquid.
