South Australia, with its 900,000 square miles of land, extending over twenty-seven degrees of latitude from the Indian to the Southern Ocean, and with a width of twelve degrees of longitude, is stated to be the largest British colony, but has a population of only 225,000. The appearance of the South Australian Court differs from the Victorian in the greater predominance of raw materials and the smaller proportion of manufactures. Copper in the ore as malachite, and in metal and manufactured forms, is one of the principal features of the court. Emeu eggs, of a greenish-blue color and handsomely mounted in silver as goblets, vases and boxes, are the most peculiar: they formed quite a striking feature at the Centennial. The resemblance of the climate to that of California is indicated in the cultivation of wheat in immense fields, which is cut by the header and threshed on the spot, also by the enormous size of the French pears, which grow as large as upon our Pacific coast. The olive also is becoming a staple, as in California, and the grape is fully acclimated and makes a very alcoholic wine. The product in 1876 was 728,000 gallons. Western Australia is among the latest settled, and has a territory of 1280 by 800 miles, of which the so-called "settled" district has an area about the size of France, with 26,209 inhabitants. It can hardly be considered to be crowded yet. Its mineral exhibits are lead, copper and tin ore; silks, whalebone; skins, those of the numerous species of kangaroo and of the dingo or native dog predominating. The woods are principally eucalypti, as might be supposed, but endogenous trees are found toward the north, and are shown. Corals and large tortoise-shells show also that the land approaches the tropics. The collection of native implements includes waddies and boomerangs, war- and fishing-spears, shields of several kinds--including one almost peculiar to the Australians, made very narrow and used for parrying rather than intercepting a missile. The netted bag of chewed bulrush-root is similar to that shown at the Centennial, but the dugong fishing-net, made by the natives of the north-west coast from the spinifex plant, I have not before observed. Western Australia was not represented at the Centennial.
