According to Kunz,1 32 stones were found by the watchman of the
Arkansas Diamond Co. in 1915. Theso stones were white, yellowish,
and brown. Three stones, transparent and perfect, weighed, respec-
tively, 0.32, 1.22, and 2.50 carats. The total weight of the stones
found was 17.9 carats.
The Kimberlite Diamond Mining & Washing Co. has been in constant
operation, according to Austin Q. Millar, washing ground from the
Kauney and the Ozark mines. It is the policy of this company to with-
hold figures of production, and the values given under the production
of diamonds are therefore too small. As soon as the company is in
a position to give figures of production, a more accurate statement
of the value of the diamonds produced in this country can be given.
The other companies in this field have not reported any production.
A detailed report of the diamond-bearing area is in preparation by
Hugh D. Miser, of the United States Geological Survey, who states
that according to reports at least 4,000 stones have been produced up
to July 1, 1916.
