from this camp more than offsets gains from such ores elsewhere. The bulk of the silver ores of this class are milled and cyanided at or near the mines, although a small quantity of richer ore is shipped to copper and lead smelters. The silver obtained as a by-product from copper, lead, and zinc ores is derived from refining the copper and lead bullion produced in smelting those and other ores.
WORLD'S PRODUCTION OF GOLD.
Value of gold produced in the world, 1860-1919.
[The annual production from 1860 to 1872 is obtained from statistics for 5-year periods compiled by Dr. Adolph Soetbeer. Since 1872 the estimates are those of the Bureau of the Mint. See PI. V.]
In 1919 the estimated total production of gold in the world de­creased $15,758,000, following a decrease of about $38,500,000 in 1918. The production in the United States decreased about $8,-300,000; Mexico, $1,576,000; Africa, $3,293,000; Australasia, $3,156,000. The production in Canada increased about $1,171,000 in 1919, and there was also a small increase in Colombia.
In the following table is shown the output of gold, by countries, as given by the Bureau of the Mint:
