A peculiar system was established for the regulation of this district. Stringent laws were passed to provide for the registering of the inhabitants, the admission of settlers, and the punishment of infringements of every kind upon the government monopoly. At first the diamond mines were rented to private individuals; but so many frauds were practised, that the government took the matter into its own hands, and worked the mines under officers of its own appointment. At present the mines are open to anybody who chooses to work them, on payment of a tax, which is placed not on the amount of diamonds obtained, but on the number of men employed. This method of collecting the tax is much more successful than the old one of levying a royalty upon the diamonds. The number of men employed can be readily counted, while, the diamonds being small, they could easily be secreted, and the payment of the proper tax evaded. [Sidenote: THE GOLCONDA MINES.] In Asia the most noted localities for obtaining diamonds are in various parts of India and the Island of Borneo. Two thousand years ago the mines of Golconda were the richest on the globe; but for some time they have been comparatively unproductive. [Illustration: WORKING A DIAMOND CLAIM IN BRAZIL.] [Illustration: RIVER WASHING—CRADLING FOR DIAMONDS.] The working of these mines is carried on very nearly in the same way as the working of the mines of Brazil. In the Brazilian mines the slaves and overseers are permitted to wear clothing, though the slaves are allowed but a very small quantity. Formerly they were compelled to work naked, to prevent their secreting diamonds. At the present time the garments they wear are subjected to the most careful examination. In the mines of India the laborers work entirely nude; but the temperature is such that they do not suffer on account of the absence of clothing. In spite of every precaution they manage to steal diamonds. They secrete them in the hair, unless their hair is cut very short. They push them into their noses, and hide them in various parts of their bodies, and in other ways. In one of the mines of Borneo there was once a laborer who managed to steal several valuable diamonds. As he wore no clothing when at work, and underwent the usual examination, he was considered entirely safe. He escaped with his prizes, became a rich man, lived contented, and died happy. In his old age he revealed the secret of his diamond thefts. [Sidenote: INGENIOUS MODE OF STEALING.]
