Oct. 27.--We travelled about seven miles up the river, to lat. 14 degrees 40 minutes in a W.S.W. course: and to long. 134 degrees 16 minutes, according to my reckoning. The range still continued along the right bank of the river; and, at length, when it ceased, another range commenced at the left bank. Here the aspect of the country changed very agreeably. Fine, well grassed plains of moderate size extended along the river, and between its numerous anabranches: for the river divided into several Pandanus channels, either running or with chains of water-holes. These plains were bounded by a range trending east and west, about two or three miles from the left bank of the river. Smoke was seen beyond it. Mr. Roper met and spoke with three natives, who did not appear to be afraid of him. Another of our horses became knocked up, and compelled us to encamp very early in the day, and, as they were all much exhausted, I allowed them to feed at large, without taking the usual precaution of keeping two tethered, in the event of being surprised by the natives. That this was intentionally taken advantage of seemed probable; for, after night-fall, at the commencement of Charley's watch, four natives sneaked up to the camp, and were preparing to throw their spears, when they were seen by Charley, who immediately gave the alarm. We got up instantly, but they had disappeared, and no one but Charley saw anything of them. I should have been inclined to consider it a hoax, had I not heard their distant cooees as late as 9 o'clock, when I silenced them by the discharge of a gun. Oct. 28.--We travelled ten miles in a north-west direction, to lat. 14 degrees 33 minutes. When we had followed the green belt of the river near four miles, Charley, who had been sent to shoot some ducks, returned, and reported that we were near the head of the river; and that he had discovered water bubbling out of the ground at the foot of a slight rise. We now followed the direction of some smoke which rose behind a large mountain; passing on our way, over an undulating country clothed with a forest of the broad-leaved tea-tree; and a scrubby flat with large melon-holes fringed with raspberry-jam trees; and through a gap between two high ranges, in which there was a small dry creek that turned to the north-east. From a large Polygonum water-hole which had recently become dry, a swarm of whistling ducks rose, probably scared by our approach. Two bustards were also seen. About three miles farther, we came to a good-sized creek, up which we proceeded until we found a small pool of water, which, after some digging, gave us a good supply. Charley had found a fine pool about four miles higher up.
