the bottom of the pocket. In addition to California and Maine, Colorado and Texas reported a small output of topaz.
TOURMALINE.
CALIFORNIA.
Bluish-green
tourmaline, of a color called Nile green, was produced from the
Mountain Lily mine near Oak Grove, San Diego County. These tourmalines
have been given the trade name of emeralite by J. W. Ware, of San
Diego. The Peter Cabat mine, about 6 miles north of Warners, Hot
Springs, has produced some good blue and light-pink tourmalines, in a
newly developed mine south of Banner, San Diego County, Bert Simmons,
of Oak Grove, has obtained green tourmalines of gem quality. Some green
crystals of good color and gem value, together with some deep blue
ones, were obtained by Roy Carson, of Pasadena, from the Panama-Pacific
Exposition group of three claims on the east side of Chihuahua Valley,
San Diego County.
MAINE.
Fine
pink and green tourmalines were found near Georgetown. The Mount
Apatite mines, near Auburn, and deposits at Paris have yielded some
tourmaline and beryl.
TURQUOISE.
Turquoise
ranks third in the value of precious stones produced in 1915,
tourmaline being very nearly of equal value. Nevada, New Mexico, and
Arizona produced the bulk of the turquoise.
A
new deposit of turquoise was discovered in the fall of 1915 by J. H.
Malloy, of Rawhide, Nev. The locality is reported as being near Rand,
about 18 miles south of Rawhide.
VESUVIANITE (CALIFORNITE).
A
small quantity of californite was extracted from the deposits at Big
Bar, Butte County, Cal. The color and quality are steadily increasing
as the workings descend from the surface, the material becoming dark
green with darker green spots. A production was also reported from
Happy Camp, Siskiyou County.
ZOISITE (THULITE).
Mr.
A. C. Taylor, of Seattle, Wash., reports that a ledge in Okanogan
County contains a large amount of rose-red stone pronounced to be
thulite, a variety of the mineral zoisite. The deposit is apparently to
be worked by the Thulite Association Claims, 427 L. C. Smith Building,
Seattle, Wash.
IMPORTS.
The
value of the imports of precious stones into the United States during
the calendar year 1915 as reported by the Bureau of Foreign and
Domestic Commerce, amounted to $26,193,862, an increase of $6,982,778
over 1914, which was the smallest since 1908.
