The prevailing rock, which crops out on the rises and often forms low cliffs, in which are receptacles for holding water, is LIGHT RED SANDSTONE (desert sandstone, tertiary). The only game found in the spinifex is a kangaroo rat, commonly called the wirrup; but in the grassy openings there are many kangaroos, and often emus, also a rat known as the wurrung. These animals are very good eating, and formed a valuable addition to our store department. At the permanent waters there were always myriads of bronze-winged pigeons, and also the white cockatoo with scarlet crest, called the chockalott; also the beaccoo, or slate-coloured parrot. Generally, however, with the exception of the crow and hawk, birds were not very numerous except round water. Whenever a sheet of water was found we found ducks, and in Lake Augusta swans and ducks were innumerable. In bringing this report to a close it is not necessary to refer much to the reasons that induced me to keep more to the south than I originally intended. It will readily be seen, after perusing this journal, that it was a necessity, and that we could not get further north. It is a marvel to me that we got through at all; the season was an exceptionally dry one--in fact, a drought--our horses were of a very ordinary kind, and the country most wretched. When it is remembered that a horse in poor condition and in warm weather cannot go much over a day without water, and when the sterility of the country is considered, it will be readily seen what a disadvantage one labours under without camels, which can go ten days without water. Well can I sympathize with Mr. Giles when he states in his journal: "All I coveted from my brother explorers was their camels, for what is a horse in such a region as this? He is not physically capable of enduring the terrors of this country." And so it is; horses are the noblest and most useful animals in the world, but they must have food and water regularly. The camel, on the other hand, is physically formed to travel over these desolate regions, and in Australia has been known to go twelve and fourteen days without water, carrying 300 pounds, and sometimes 400 pounds weight. From these few remarks it will be seen what a great disadvantage Mr. Giles and myself laboured under compared with Major Warburton and Mr. Gosse; and what in similar circumstances might have been easily performed by them was quite impossible in our circumstances.
