WORLD'S PRODUCTION OP SILVER.
The figures for the world's production of silver in 1918 show that the United States and Canada produced about 89,100,000 ounces, or about 45 per cent, against 57 per cent in 1917, and that Mexico, Central America, and South America yielded nearly 81,000,000 ounces, or 41 per cent, so that approximately only 27,300,000 ounces of silver came from all other countries, mainly from Australasia, Japan, and Spain.
There was an increase of 27,500,000 ounces in the quantity of silver produced in Mexico in 1918, but the production from mines in the United States decreased about 3,930-000 ounces and that from Canada 937,000 ounces.
The total increase in the world's production of silver in 1918 was about 23,200,000 ounces, due entirely to the large increase in Mexico, for the total from all other countries decreased more than 4,000,000 ounces, notwithstanding the much higher average selling price of silver in 1918.
