variety, such as canes, paper-weights, writing-cases, perfume-bottles, fan-sticks, bracelets, watch-chains, and lace-pins, the lat­ter in such designs as shovels, picks, and other mining emblems. In certain new furniture, it has been used as paneling; and here, as in jewelry, the effect is better brought out by added colors, such as are afforded by agate, moss agate, native silver in a matrix, smoky quartz, iron and copper pyrite, cinnabar, mala­chite, turquoise in the matrix, and other bright minerals. By slitting and piecing, as is done with malachite, an entire table-top can be made from a few pounds of gold quartz. Much of the jewelry made of this material is sold to tourists from the Eastern States and elsewhere. Eleven hundred dollars worth was purchased, some years ago, by an Asiatic embassy, and scarcely any one visiting California fails to secure a specimen. The best taste is not often exercised in the designs for this ma­terial. Many are too large and ungainly for personal adorn­ment, and others are not as well mounted as the jewelry sold with them. There is much room for improvement in these re­spects. One of the large designs made of gold quartz, represent­ing the Cathedral of Notre Dame, at Paris, is valued at $20,000. It stands about a foot high, and is perhaps the finest piece of gold quartz work ever produced. A mass of gold quartz1 weighing 160 pounds was taken out of the bank of the Nevada Hydraulic Company at Gibsonville, Cal. The boulder was smoothly washed and had the appearance of having been ground in a pothole. Its estimated value was $2,500, but its real worth was more than this, since it was valuable for lapidary purposes. The gold penetrating amethystine quartz from Hungary is very beautiful, but the California quartz is the finest known.
Some years ago a method was devised of fusing quartz, by throwing in lumps of heavily alloyed gold, and allowing the ma­terial to cool in molds of required shapes. It was said that the mingling of the metal and the quartz was complete, but the quartz had a milky, unnatural, glasslike appearance entirely un­like the gold quartz it was intended to represent. The firm of LeDuc, Connor & Laine, in San Francisco, applied for a patent for an imitation gold quartz produced by means of electricity,
