Defiance, Fort Wingate, etc., who in turn send them to large cities in
the East in parcels weighing from half an ounce to thirty or forty
pounds each. These garnets, which are locally known as Arizona and New
Mexico rubies, are the finest in the world, rivaling those from the
Cape of Good Hope. Fine gems weighing from two to three carats each
and upward when cut are not uncommon. The peridots found associated
with garnets are generally four or five times as large, and from their
pitted and irregular appearance have been called "Job's tears." They
can be cut into gems weighing three to four carats each, but do not
approach those from the Levant either in size or color.

_Gold Quartz._--Since the discovery of gold in California, compact
gold quartz has been extensively used in the manufacture of jewelry,
at one time to the amount of $100,000 per annum. At present, however,
the demand has so much decreased that only from five to ten thousand
dollars' worth is annually used for this purpose.

In addition to the minerals used for cabinet specimens, etc., there is
a great demand for making clocks, inkstands, and other objects.

_Quartz._--During the year 1887 about half a ton of rock crystal, in
pieces weighing from a few pounds up to one hundred pounds each, was
found in decomposing granite in Chestnut Hill township, Ashe County,
North Carolina. One mass of twenty and one-half pounds was absolutely
pellucid, and more or less of the material was used for art purposes.
This lot of crystal was valued at $1,000.

In Arkansas, especially in Garland and Montgomery Counties, rock
crystals are found lining cavities of variable size, and in one
instance thirty tons of crystals were found in a single cavity. These
