Some natives followed us during a part of this day, shouting, and at length came boldly up to the head of the column. They were very greedy, coveting everything they saw; and holding out their hands, uttering constantly, in an authoritative tone, the word occa! which undoubtedly means give! I had not been in their presence one minute before their chief, a very stout fellow, drew forth my pocket-handkerchief, while a boy took my Kater's compass from the other pocket and was on the point of running off with it. I gave a clasp-knife to the chief, when another of the party most importunately demanded a tomahawk. Observing that he carried a curious stone hatchet I offered to exchange the tomahawk for it, to which he reluctantly agreed. I left them at last disgusted with their greediness; and I determined henceforward to admit no more such specimens of wild men to any familiarity with my clothes, pockets, or accoutrements. They paid no attention to my questions about the river. When the party moved on they followed, and when I halted or rode back they ran off; thus alternately retiring and returning, and calling to the men. At last I galloped my horse at them, whereupon they disappeared altogether in the bush. At 10 1/2 miles we came upon the river, and encamped where it was very deep and broad, the banks and also the flood marks being much lower than further up the Darling. June 16. We were compelled to turn east for half a mile to clear a bend in the river to our left, which, impinging upon some rather high ground, left us no very good passage. The course of the river lower down was such that after travelling many miles to the south-west, and two to the west and north-west, I was obliged to encamp without being able to find it. By following a hollow however which descended in a north-east direction from our camp, the river was discovered by our watering party in the evening at the distance of about three miles. The country which we had crossed this day was of a somewhat different character from any yet passed, consisting of low, bare eminences, bounding extensive open plains on which were hollows on a clay bottom surrounded by Polygonum junceum, and evidently the receptacles of water at other times. The hills, if the bare eminences might be so-called, were composed of a red sandy soil producing only salsolae and composite plants, but no grass. This red sand was so loose that the wheels of the carts sank in it at some places to the axles. There were bold undulations where we encamped; all declining towards the hollow connected with the river. There was also a little hill overlooking plains to the north and west. We passed a solitary tree of a remarkable character, related to Banisteria, the wood being white and close-grained, much resembling beech. As it pleased the carpenters I gathered some of the seeds. This evening by observation of the star alpha Crucis I ascertained the variation to be 7 degrees 52 minutes 15 seconds East. June 17.
