In the early days at the diamond mines, there was a good deal of rioting and trouble. There was not much observance of law, mainly for the reason that there was no law. But at present, every thing is orderly and peaceable. The diamond fields are partly in regions controlled by the British government, and partly in the Republic of the Orange Free States. The latter country became known to many Americans through the Centennial Exhibition at Philadelphia, in 1876. It had a small display, but a very attractive one. First and foremost, of course, were the diamonds in the rough, which included many specimens of stones, varying in color and size. Then came a quantity of the soil in which the gems are found, and then the pebbles which accompany the diamonds. Copper, iron, and other ores were exhibited; many excellent specimens of leather were displayed; there was a collection of stuffed birds; there were tusks of ivory, skins of various wild beasts, specimens of wool, and a model of the carts used to convey it to the coast. The great business of the country is in grazing, and the sheep and cattle in its limits may be counted by millions. Its population is estimated at about one hundred thousand, of which three-fourths are whites. Of late years, the farmers have found an excellent market for many articles of produce, by taking them to the diamond mines. [Sidenote: SCENE AT AN AUCTION.] The scene at the sale of edibles is a curious one. As the fields became thickly populated, there was a great demand for fruits and vegetables, and the farmers sent in everything they could spare. At one time, oranges sold for twenty-five cents each, potatoes for seven cents a pound, and eggs one dollar and twenty-five cents a dozen. Nearly everything was sold at auction, the farmers arranging the things in lots to suit purchasers, and then submitting them to the care of the market master. The scene at an auction is thus described:
