Several considerable plains were noticed to our right, stretching east and west, which were generally rich in point of soil; but we passed through much brushy land during the day. It was lamentable to see the state of vegetation upon the plains from want of moisture. Although the country had assumed a level character, and was more open than on the higher branches of the Macquarie, the small freestone elevations, backing the alluvial tracts near the river, still continued upon our right, though much diminished in height, and at a great distance from the banks. They seemed to be covered with cypresses and beef-wood, but dwarf-box and the acacia pendula prevailed along the plains; while flooded-gum alone occupied the lands in the immediate neighbourhood of the stream, which was evidently fast diminishing, both in volume and rapidity; its bed, however, still continuing to be a mixture of sand and clay. The cattle found such poor feed around the camp that they strayed away in search of better during the night. On such an occasion Botheri and his fraternity would have been of real service; but he had decamped at an early hour, and had carried off an axe, a tomahawk, and some bacon, although I had made him several presents. I was not at all surprised at this piece of roguery, since cunning is the natural attribute of a savage; but I was provoked at their running away at a moment when I so much required their assistance. Left to ourselves, I found Mr. Hume of the most essential service in tracking the animals, and to his perseverance we were indebted for their speedy recovery, They had managed to find tolerable feed near a serpentine sheet of water, which Mr. Hume thought it would be advisable to examine. We directed our course to it as soon as the cattle were loaded, moving through bush, and found it to be a very considerable creek that receives a part of the superfluous waters of the Macquarie, and distributes them, most probably, over the level country to the north. It was much wider than the river, being from fifty to sixty yards across, and is resorted to by the natives, who procure muscles from its bed in great abundance. We were obliged to traverse its eastern bank to its junction with the river, at which it fortunately happened to be dry. We had, however, to cut roads down both its banks before we could cross it; and, consequently, made but a short day's journey. The soil passed over was inferior to the generality of soil near the river, but we encamped on a tongue of land on which both the flooded-gum and the grass were of luxuriant height. We found a quantity of a substance like pipe-clay in the bed of the river, similar to that mentioned by Mr. Oxley. GREAT HEAT.
