To-morrow I am off; it is useless to remain in a region such as this. But where shall I go next? The creek I had last got water in, might even now be dry. I determined to try and reach it farther down its channel. If it existed beyond where I left it, I expected, in twenty-five to thirty miles, in a southerly direction, to strike it again: therefore, I decided to travel in that direction. A few quandongs, or native peach trees, exist amongst these gullies; also a tree that I only know by the name of the corkwood tree. ("Sesbania grandiflora," Baron Mueller says, "North-Western Australia; to the verge of the tropics; Indian Archipelago; called in Australia the corkwood tree; valuable for various utilitarian purposes. The red-flowered variety is grandly ornamented. Dr. Roxburgh recommends the leaves and young pods as an exquisite spinach; the plant is shy of frost.") The wood is soft, and light in weight and colour. It is by no means a handsome tree. It grows about twenty feet high. Generally two or three are huddled together, as though growing from one stem. Those I saw were nearly all dead. They grow in the little water channels. The ants here, as in nearly the whole of Tropical Australia, build nests from four to six feet high--in some other parts I have known them twenty--to escape, I suppose, from the torrents of rain that at times fall in these regions: the height also protects their eggs and stores from the fires the natives continually keep burning. This burning, perhaps, accounts for the conspicuous absence of insects and reptiles. One night, however, I certainly saw glowworms. These I have only seen in one other region in Australia--near Geelong, in Victoria. A tree called the native poplar (Codonocarpus cotinifolius) is also found growing in the scrubs and water-channels of this part of the country. The climate of this region appears very peculiar. Scarcely a week passes without thunderstorms and rain; but the latter falls in such small quantities that it is almost useless. It is evidently on this account that there are no waters or watercourses deserving of the name. I should like to know how much rain would have to fall here before any could be discovered lying on the ground. All waters found in this part of the country must be got out of pure sand, in a water channel or pure rock. The native orange-tree grows here, but the specimens I have met are very poor and stunted. The blood-wood-trees, or red gum-trees, which always enliven any landscape where they are found, also occur. They are not, however, the magnificent vegetable structures which are known in Queensland and Western Australia, but are mostly gnarled and stunted. They also grow near the watercourses.
