DIAMOND: OCCURRENCE IN BORNEO ^I'J' De Beer's and Kimberley mines, among whom representatives of almost every South African tribe are to be found, live in what is known as a compound, and are debarred from all intercourse with the outside world. This compound is a rigidly guarded enclosure, several acres in extent, in which all the necessaries of life can be purchased as well as other objects specially attractive to the native taste. Water, wood, and medical attendance are supplied to the workers gratuitously, and no effort is spared to make their enforced stay as little irksome as possible.

Before leaving the compound, however, an exhaustive search of his person and belongings is made, and he has further to submit to the administering of a strong purgative. In spite of the restrictions by which life in the compound is hedged in, and the absolute prohibition laid on the sale of intoxicating liquors, the workers are by no means averse to the system, and often renew their contracts again and again.
