GEMS AND PRECIOUS STONES.                              855
RHODONITE. OREGON.
A vein of rhodonite 4 feet wide is reported by Mr. D. B. Bubar, of Roseburg, Oreg., to have been found near the caves on Caves Creek, Josephine County. Preliminary work showed considerable material available and slabs 6 by 8 inches could be obtained. The rhodonite is said to be of good quality and to take a fine polish.
STATTROLITE.
MINNESOTA.
Mr. T. C. Wing, of St. Cloud, Minn., has sent in samples of stauro-lite from the banks of the Mississippi about 25 miles north of St. Cloud and about 3 miles from Royalton. Many of the crystals are twinned so as to form the usual crosses, but perfect ones are not comĀ­mon. The crystals, as much as an inch in length, are found loose in the soil, in a blue clay, and also in the schist matrix. Bowlders 3 feet thick contain numbers of the crystals. The mineral is dark brown and unaltered, and therefore too hard to be finished off smoothly for the jewelry trade like the similar stones from Virginia.
VIRGINIA.
The staurolites, better known as "fairy stones," are found in a field of about 50 acres on top of Bull Mountain, Patrick County, and have a ready sale. These "fairy" or "lucky" stones are twinned stauro-lite crystals simulating the Roman, Maltese, and St. Andrew's crosses. They are as much as an inch in length and are of a dark-brown color. The original staurolite mineral has changed to a compact softer mateĀ­rial, so that the stones can readily be prepared for the jewelry trade. A brisk trade in these popular stones is reported; they are mounted as cuff links, scarfpins, brooches, charms, and in many other ways.
TIIOMSONITE.
An occurrence of thomsonite in an amygdaloidal rock in Cook County, Minn., about 7 miles from Grand Marais, has been wTorked by Alfred Merritt, of Duluth, Minn. A number of stones of gem quality are said to have been obtained, and Mr. Merritt intends soon to mine and market the stones. The colors vary from a light yellow or brown to a dark green, with many intermediate shades. Those stones which are cut so as to show a central eye are in good demand, being used for settings in scarfpins, cuff links, brooches, etc.
The mineral is also reported from Lane County, Oreg., in a road cut 100 yards west of Deerhorn; also in the gravel of Willamette and McKenzie Rivers, near Eugene.
TOPAZ.
Mr. H. C. Gordon, of San Diego, Gal., reports that about 30 crystals of bluish topaz, some of them containing gem material, were taken from the Mountain Lily mine, near Oak Grove, San Diego County.
Several pockets of topaz crystals were opened by F. H. Peterson, of Fryeburg, Maine. The topaz was scattered through the black dirt in
