Fig. 92. In gold mining South Africa easily leads the world. The Transvaal produces more 
than three times as much gold as the United States (including Alaska), and almost seven times 
as much as Australia. Canada, Mexico, South America. India. Russia, and Japan together 
mine less than half as much as South Africa. 
In the production of silver, Mexico stands first, and the United States second. Within the 
United States, Utah leads in silver and California in gold; almost all the silver, as well as the 
gold, comes from west of the Great Plains. 
(Note that values, not quantities, are here represented. If quantities were represented and the gold 
bars remained as above, the bar for silver in Mexico would have to extend over the whole map.)

Fic. 93. Tin is the only one of the seven chief metals whose main centers of production are in 
southeastern Asia. The Malay Peninsula and the East Indies produce half the world’s supply. 
North America has no tin, and Europe has only a little in Great Britain and Spain. In Africa, 
Nigeria and South Africa produce small amounts, as does Australia. The entire South American 
supply (about a fourth of the world’s total) comes from Bolivia. In Asia. China and Siam to- 
gether produce about an eighth.
