QUARTZ. ARKANSAS.
Mr.
Francis Holstein, of De Eoche, Ark., states that a quantity of the
quartz crystals from near that place are still sold to visitors and
jewelers at Hot Springs. These quartz crystals range in size from small
specimens up to fine cabinet specimens. They vary from colorless and
limpid to light and very dark smoky brown. Inclosures of phantom
crystals and bubbles are present in some specimens. Bright lustrous
faces are characteristic of these Hot Spring County quartzes, and
occasional crystals show an unusual development of planes. Others are
variously etched. Mr. Holstein states that the quartz crystals are
obtained chiefly from pockets where they are imbedded in red clay.
MAINE.
Minerals
of interest because of their semigem nature are found at the J. A.
Hibbs feldspar and mica quarry, a little over a mile northeast of
Hebron, in Oxford County, Me. These minerals are translucent quartz
and beryl. The quartz varies from colorless to pale rose, light and
dark smoky brown, and yellowish. Specimens were seen in which there
were rounded patches of dark smoky brown in
S
quartz of lighter
color. The beryl is mostly opaque grayish-green, Other associated
minerals are potash feldspar, mica, and black tourmaline.
RHODONITE.
COLORADO.
Mr.
J. D. Endicott, of Canon City, Colo., reports the discovery of a
deposit of rhodonite about 10 miles southeast of that place. He states
that the deposit will yield a quantity of mineral with good pink color
and of fine texture.
RUBY.
NORTH CAROLINA.
Tests
were made on the ruby deposits along Caler Fork of Cowee Creek in Macon
County, N. C, during the last part of 1913. Prospecting was under the
charge of N. E. Isbell, of Cincinnati, who had charge of the
developments here several years before. Mr. Isbell used a churn drill
during this work, going to a depth of 65 feet at the''In Situ" Hill
locality. Some ruby and sapphire of marketable color were found along
with opaque corundum. During the first part of 1914 better equipment in
the way of a 3-inch core drill operated by a 10-horsepower gasoline
engine was installed, and a number of holes will be sunk at the "In
Situ" Hill locality to a depth of about 150 feet.
SPODUMENE.
CALIFORNIA.
Operations
of the Pala Chief Gem Mining Co., at the Pala Chief mine and the
Tourmaline Queen mine, near Pala, San Diego County, Cal., resulted in a
production of more of the lilac-colored spodumene
