The bed was sandy, but contained water in abundance, so that I hoped it would lead us to higher regions, by following it upwards, to where other waters might fall in the direction of the Gulf. This river contained the Harlequin fish of the Maranin great abundance. Yet we had found none of these in the river to which this was a tributary, but, on the contrary, two other sorts. There was much novelty in the trees and plants. One tree in particular, growing in the bed of the river, had the thin white shining bark of the tea-tree (mimosa), and drooping leaves shaped like those of the eucalyptus; a HIBISCUS allied to, if not the same, with II. LINDLEYI, but not in flower; a CASSIA, perhaps C. CORONILLOIDES in ripe fruit, or at least closely allied to it, occupied the dry sandy ground with MONENTELES REDOLENS, a silveryheaded weed; and some Cinchonad allied to Coffea, with young fruit, the size of small olives. Latitude, 22 deg. 23' 10". Thermometer, at sunrise, 21 deg.; at noon, 59 deg.; at 4 P.M., 64 deg.; at 9, 37 deg.; with wet bulb, 28 deg.. (LXVI.) 4TH AUGUST.--We had still so much westing to make, in order to hit the head of the Gulf, that I was disposed to follow up the new river in any direction that did not take us much to the S. The river, however, was soon found to come from the S.W. and S., so that I was obliged to cross it. I then travelled W. through open forest three miles, which brought us to undulating ground. I then turned to the W.N.W., and proceeded over ground equally open and favourable for the passage of our carts. At length, a hard ferruginous conglomerate rock, projected from the surface, and clumps of thick brigalow grew on some of the summits. On one piece of rising ground, I found a mass of rocks, a few feet higher than the rest, and from it I perceived a continuation of the slightly elevated flattopped range, to the southward and westward. A somewhat higher but similar sort of range appeared in the east, beyond a very broad and level woody country, through which it was probable that our first-found river still pursued a northerly course. Beyond that flat, and further to the eastward, the same hills already seen were still visible, and others northward of them, just like them. There was a high summit beyond all these bearing about E. I could not discover any satisfactory line to follow in the country thus partially visible, and as the sun was near the horizon, I only continued, to go forward to a valley wherein I hoped to have found water, but was disappointed, the soil being too sandy and absorbent. There we nevertheless encamped, in Lat. 22 deg. 19' 45" S. On this day's journey, I saw two of the rose-coloured paroqueets of the Barwan, none of these birds having been seen by any of the party since we crossed the Culgoa. A fragrant stenochilus, with leaves smelling exactly like mint, was found this day, and a splendid banksia in flower, also a new
