Sept. 6.--We travelled twelve miles north-west, through Pandanus and bloodwood forest, alternating with scrub, stringy-bark forest, and tea-tree thickets; and, in the latter part of the stage, through broad-leaved tea-tree forest. We encamped at a fine river, with a bed three hundred yards broad from bank to bank, but with a narrow channel of running water. This channel was fringed with the water Pandanus, which we first observed at Beames's Brook; the sandy bed was covered with drooping tea-trees and Grevillea chrysodendrum. Charley shot a bustard, the stomach of which was filled with seeds of Grewia, with small yellow seeds, and some beetles. On this stage, we again passed some of those remarkable dry tea-tree swamps--surrounded with heaps of very large mussel shells--evidently showing that they had been a long time under water, though they were now overgrown with small tea-trees, perhaps five or six years old; and which proved, like the drooping tea-trees on the banks of the creek, that the last few years had been exceedingly dry. I supposed the river to be the Van Alphen of the Dutch navigators, as its latitude, where I crossed it, was about 16 degrees 41 minutes, and its longitude I calculated to be 137 degrees 48 minutes. Sept. 7.--We travelled about nine miles N. N. W. to latitude 16 degrees 35 minutes; the first part of the stage was scrubby, the latter part undulating with a fine open stringy-bark forest. The trees were tall, but rarely more than a foot in diameter. Here we met with hard baked sandstone, of a whitish grey colour. About seven miles from our camp, we saw a low blue range to the westward; and, soon after, passed a sandy Pandanus creek, with scrubby broken banks: this was joined by a second, and both together entered a broad tea-tree creek, coming from the south-west, in which we found a fine pool of water covered with white and yellow Villarsias and yellow Utricularias. The rose-coloured Sterculia, and a smooth broad-leaved Terminalia, were observed on the sandy flats of the creek; and a small fan-leaved palm (Livistona humilis, R. Br.), a small insignificant trunkless plant, growing between sandstone rocks, was here first observed. A taller species of this palm, as we subsequently found, formed large tracts of forest on the Cobourg Peninsula, and near the Alligator rivers.
