We descried, from a tree not far from the camp, hills to the westward, and the interest with which we now daily watched the horizon may easily be imagined, for on the occurrence and direction of ridges of high land depended the course of the Darling and its union with other rivers, or discharge into the sea on the nearest line of coast. A range extending from west to north-west was in sight, also a lower ridge, but apparently on the other side of the river. The cattle having separated on its banks during the night they were not brought up so early as usual; and in the interim I endeavoured to repair the barometer, which was out of order. This accident had occurred in consequence of the man having carried it, contrary to my orders, slung round his body instead of holding it in his hand. Much of the quicksilver had shaken out of the bag and lodged in the lower part of the cylinder; but by filing the brass and letting off this mercury the instrument was rendered once more serviceable. We travelled this day due west, and at the end of 7 1/2 miles we encamped on a bend of the river where the water was deep, and the banks rather low, but very steep. The sky became overcast, almost for the first time since we had advanced into these interior regions, and at sunset it began to rain. The position of the hills and the direction of the river were here particularly interesting, as likely soon to decide the question respecting the ultimate course of this solitary stream on which our lives depended in this dry and naked wilderness! June 18. The morning was fine as usual, the rain which fell during the night had only laid the dust. We proceeded south-west until the bends of the river obliged me to move still more to the southward. The hills on the opposite bank at length receded, and we saw before us only a wide desert plain where nothing seemed to move, and the only indication of life throughout this melancholy waste was a distant column of dark smoke ascending in remarkable density to the sky. In the afternoon, the wind blowing keenly from the west-south-west, we encamped amongst some polygonum bushes near the river after travelling 10 1/4 miles. June 19. A thick haze came on, with an extremely cold wind from the south-west; and as it was necessary to look well before me in this part of our journey, I gave the men and cattle the benefit of a day's rest. The river was so shallow that it seemed almost possible to step across it; and no deep reaches appeared in its bed. This probably was the reason why no natives were in the vicinity, as in such deep parts only can they find fish. The quantity of water continued the same as when we first came on the river 120 miles higher up. GRASS PULLED AND PILED IN RICKS BY THE NATIVES.
