August 3.--We travelled, for the first two miles, N. 60 degrees W. over scrubby ironstone ridges, and then entered upon a fine plain, from which smoke was seen to the west and north-west. I chose the latter direction, and passed over ironstone ridges covered with stunted silver-leaved Ironbark; and a species of Terminalia, a small tree, with long spathulate glaucous leaves, slightly winged seed-vessels, and with an abundance of fine transparent eatable gum; of which John and Brown gathered a great quantity. Some of the ridges were openly timbered with a rather stunted white-gum tree, and were well grassed; but the grass was wiry and stiff. At the end of our stage, about sixteen miles distant from our last camp, we crossed some rusty-gum forest; and encamped at a fine water-hole in the bed of a rocky creek, shaded by the white drooping gum, which seemed to have taken the place of the flooded gum. Groves of Pandanus spiralis grew along the creek, which ran to the north by east. All the small watercourses we passed, inclined to the eastward. Charley found the shell of a Cytherea on an old camping-place of the natives, which indicated our approach to the salt water. A native had carved a representation of the foot of an emu in the bark of a gum-tree; and he had performed it with all the exactness of a good observer. It was the first specimen of the fine arts we had witnessed in our journey. August 4.--We travelled about ten miles west-north-west, over scrubby ridges, plains, and box-flats. In a patch of rusty-gum forest we found Acacia equisetifolia, and the dwarf Grevillea of the upper Lynd in blossom; the thyrsi of scarlet flowers of the latter were particularly beautiful. As we entered into the plains, Binoe's Trichinium and Salicornia re-appeared.
