The principal trees in Australia are the gum, stringy bark, manna tree, wild cherry (so called), iron bark, shea oak, peppermint, acacia, and the mimosa, which last, however, should more properly be called a shrub. These and others, like the Indian malelucas, are remarkable for the Cajeput oil contained in their leaves, and in the gums which exude from their sterns, and in this point of view alone, considering their boundless number, their value can hardly be over estimated. The gum of some of the acacias will bear comparison with gum-arabic. Their bark and timber are likewise useful, and when the gold fever has subsided, will become valuable as exports. Wild flowers there are in abundance, and some exquisite specimens of ferns. For the benefit of those better skilled in botany than myself, I give the following list of Dr. Muller's indigenous plants of Victoria. Correaochrolenca and Phebalium Asteriscophorum, both with the medical properties of the Bucco-bush, Eurybia Rhodochaeta, E. Rugosa, E. Adenophylla, E. Asterotristia, Sambucus, Gaudichaudiana, Prostanthera Hirsuta, Pimelea axiflora (powerful Surrogat of the Mezerion shrub), Bossidea decumbcus, Asterotristia asperifolia, Patersonia aspera, Grevilliea repens, Dallachiana, &c. The geranium, fuschia, rhododendrum, and almost all varieties of the Cacti have been taken to the colonies, and flourish well in the open air all the year round, growing much more luxuriantly than in England. The vineyards must some day form a considerable source of employment and profit to the colonists. The wine made in Australia is very good. The vines are cultivated in the same manner as in France. In the neighbourhood of Sydney, oranges and peaches are grown out in the open air. Apples and other fruits flourish well in Van Diemen's Land. All these fruits are not indigenous to Australia. The only articles of food natural there, are the kangaroos, emus, opossums, and other denizens of the forest, a few snakes, some roots, and a worm, about the length and thickness of a finger, which is abundant in all parts of the colony, and is taken out of the cavities, or from under the bark, of the trees. It is a great favourite with the blacks, as it can be procured when no other food is attainable.
