8TH MARCH.--The view northward from our present camp was most extensive. Far in the northeast a yellow slope presented the unusual appearance there, of a cultivated country. It was doubtless ripe grass, yet still the earth there had not even been imprinted with any hoof. Between that slope and our camp, lay the element, in abundance, which had been so scarce on the other side of the Darling. To the northward, at no great distance, was the river, where, as our guides informed us, we should no longer be ill off for water in pursuing our journey along its banks. I set the carpenter to cut sleepers and slabbing to enable us to bridge the muddy creek, for I had examined it early in the morning, and had crossed it with my horse; although I found several watercourses almost as soft, beyond. The natives maintained that the water in this extensive swamp came neither from the east nor west, but from the river directly before us, which came from the northward. Just behind our camp, to the southward, was a gentle elevation, almost a hill, consisting of the usual rock, felspar; and it seemed to me that this stony ground alone impeded the further progress of the water towards the Barwan. The ridge trended north-west, as most others did in this extensive basin; and this direction being nearly parallel to that of the coast ranges further northward, seemed to afford additional reason for expecting to find anticlinal and synclinal lines, and, consequently, rivers, much in the same direction. D'Urban's group, distant 150 miles lower down the Darling, consisted of a quartzose rock, exactly similar to this, exhibiting a tendency, like it, to break into irregular polygons, some of the faces being curved. This rock is most extensively distributed in the interior of New South Wales. It was not until the evening of this day that the approach of the drays was announced, and then prematurely, the teams only having been brought forward to the water without them. So weak were the unfortunate animals, that not even by night, nor by doubling the numbers, could they be made to draw the drays forward, for the short distance of eight miles; a distance which we had been given to understand was so much greater. Forward, all was most promising, and it may be imagined how bitterly I regretted the alteration of my original plan of equipment, which had reference to horses and light carts alone. A new species of ANTHISTIRIA occurred here, perfectly distinct from the kangaroo grass of the colony, very like APLUDA MUTICA, and remarkable for the smooth shining appearance of the thin involucral leaves.[*] The TRICHINIUM ALOPECUROIDEUM, in great abundance, was conspicuous, with its long silky ears of green flowers. On the stony ground occurred a very curious new woolly KOCHIA [**], also a species of CYPERUS; the TRICHINIUM LANATUM in great perfection; a grass resembling the close reed (CALAMAGROSTIS of England), and which proved to be the little-known TRIRAPHIS MOLLIS. On the margin of the morass the DACTYLOCTENIUM RADULANS, spreading over the interstices, reminded the traveller of the grasses of Egypt; and, in stony ground near the morass, we observed the JUSTICIA MEDIA of Brown. Thermometer at sunrise, 66°; at noon, 98°; at 4 P. M. 102°; at 9, 81°; ditto with wet bulb, 74°.
