The last region of which we have any account is known as Kimberley, and a city of ten thousand inhabitants, with banks, hotels, churches, and theaters, has grown up there. In its general features, it is not unlike a frontier city in California or Colorado, except that its streets are filled with carts carrying earth away from the diggings, and with great numbers of negroes who come to work in the mines. The diamonds are found in a conglomerate which is dug up from the bottom of what has once been a deep cañon. At Kimberley, the cañon is two hundred feet deep, and one thousand feet across. When one descends into this place, it is almost impossible to hear the human voice, on account of the noise made by the wheels and buckets, and the picks, shovels, and other tools of the miners. In the early times of the mining excitement at the Cape, the negroes were reasonably honest, but association with the white man has made them otherwise. When they can steal the diamonds they do so. They will secrete them in their ears, their mouths, or their noses, and a negro has been known to work an entire day with two or three diamonds concealed between his toes. [Sidenote: HOW AN ENGLISHMAN LOST A DIAMOND.] An interesting story is told of how an Englishman lost, one day, a valuable diamond, through his impetuosity. He had found a very large and fine stone at the bottom of his pit, and was coming up the ladder, carrying the diamond in his mouth. A negro happened to shake the top of the ladder, whereupon the Englishman proceeded to swear at him, as an Englishman might be expected to do. The result was, the diamond fell from his mouth down into the pit or into a neighboring one, and its whereabouts was never discovered by the unlucky finder. We have heard of mouths that speak pearls, but it is rarely the case that one hears of a mouth swearing diamonds.
