[4] A medical study in France during the early twentieth century suggests that gold is an effective treatment for rheumatoid arthritis. [2] While diamond mining has been taking in place in South Africa for almost a century and a half, the country's diamond sector is far from reaching the end of its life. Developments at the country's three largest mines are designed to expand their outputs and to extend their lives to anywhere between a quarter and a half a century.

Economic Exploitation

century of reliance on foreign labor re-serves for the majority of such labor.2 These dramatic events are examined here in the context of an econometric model of the demand for labor by the South African mining sector from 1946 to 1980.

Copper mining was revived along Lake Superior about 1842 and made a sudden jump. The California gold fever of 1849 was the beginning of the search and procurement of that metal on a considerable scale. Petroleum came prominently into notice for the first time in August 1859, when the Drake Well struck oil; and the Comstock Lode was discovered in Nevada that same year, and laid the foundation
