white variety occurring at the Cullakenee Mine, Clay County, also large
crystals in the trap at Shiloh Church. On the road to Charlotte,
Mecklenburg County, and near Bakersville, North Carolina, specimens
showing a slight blue chatoyancy are also found. This domestic
labradorite is scarcely used at all in the arts, as the mineral from
Labrador is cheaper and of a much superior quality, and takes a finer
polish.
At
Pike's Peak, Col, amazonstone is found in cavities in a coarse
pegmatite granite with smoky quartz crystals, often of huge size,
flesh-colored and white feldspars. When associated with smoky quartz,
it makes a most pleasing and effective miner-alogical combination. The
mineral here is finer than any found elsewhere. Many thousand

beautiful green color have been obtained, measuring from 1/2 inch
to over 12 inches in length and of different shades of green, from the
lightest and most delicate to a deep apple-green. The crystals are
often in groups, the bases of which are covered with white albite. The
finest group of this character is in the New York State Museum in
Albany, and the finest single crystals are in the collections of
Clarence S. Bernent of Philadelphia and Frederick A. Canfield of Dover,
N. J. When this mineral was first exhibited at the World's Fair in
Philadelphia, in 1876, it proved a great surprise to many, but
especially to the Russians, who had brought over some small crystals
valued at what would now be considered fabulously high prices. Some of
it is cut into gems or ornamental stones, and large quantities are
still sold annually to tourists. Several localities in North Carolina
also furnish this mineral. Rockport, Mass., formerly afforded many
finely colored pieces. Some fine green crystals have also been found at
Paris, Me., and at Mount
