The diamonds have their home in beds of clay, which are usually covered with calcareous rock. These beds are the remains of mud pits, due to volcanic action. Mr. Bryce, in his "Impressions of South Africa, says:—
"Some of the mines are worked to the depth of 1200 feet by shafts and subterranean galleries. Some are open, and these, particularly that called the Wesselton Mine, are an interesting sight. This deep hollow, one-third of a mile in circumference and 100 feet deep, enclosed by a strong fence of barbed wire, is filled by a swarm of active Kaffir workmen, cleaving the 'hard blue' with pickaxes, piling it up on barrows, and carrying it off to the wide fields, where it is left exposed to the sun, and, during three months, to the rain. Having been thus subjected to a natural decomposition, it is the more readily brought by the pickaxe into smaller fragments before being sent to the mills, where it is crushed, pulverised, and finally washed to get at the stones. Nowhere in the world does the hidden wealth of the soil and the element of chance in its discovery strike one so forcibly as here, where you are shown a piece of ground a few acres in extent, and are told, 'Out of this pit diamonds of the value of £12,000,000 have been taken.' Twenty-six years ago the ground might have been bought for £50."
To encourage honesty in the miner good wages are given, and ten per cent. is allowed to finders of valuable stones who voluntarily deliver these to the overseer. Apropos of this subject, Mr. Bryce relates an amusing tale, which, if not true, is certainly ben trovato: "I heard from a missionary an anecdote of a Basuto who, after his return from Kimberley, was describing how, on one occasion, his eye fell on a valuable diamond in the clay he was breaking into fragments. While he was endeavouring to pick it up he perceived the overseer approaching, and, having it by this time in his hand, was for a moment terribly frightened, the punishment for theft being very severe. The overseer, however, passed on. 'And then,' said the Basuto, 'I knew that there was indeed a God, for He had preserved me.'"
Before leaving the subject of diamonds, it may be interesting to note the material increase of the products of the mines year by year. The following is a table of statistics of the De Beers Consolidated Mines, Limited, since its formation, 1st April 1888:—
