About three miles above the junction of the Wilton with the Roper, we again encamped on the steep banks of the latter, at a spot which I thought would allow our horses and cattle to approach in safety. One unfortunate animal, however, slipped into the water, and every effort to get him out was made in vain. Its constant attempts to scramble up the boggy banks only tired it, and as night advanced, we had to wait until the tide rose again. I watched by him the whole night, and at high water we succeeded in getting him out of the water; but he began to plunge again, and unfortunately broke the tether which had kept his forequarters up, and fell back into the river. At last I found a tolerable landing place about fifty yards higher up; but, as I was swimming with him up to it, and trying to lead him clear of the stumps of trees, he became entangled in the tether rope by which I guided him, rolled over, and was immediately drowned. This reduced our number of horses to nine. When the other horses were brought to the camp, another rushed into the water, but I swam with him at once to the good landing place, and we succeeded in saving him. I. started late on the 24th Oct. and travelled over a country similar to that of our late stages. About a mile up the river, a ledge of rocks crossed the bed, over which a considerable stream formed a small fall and rapids; above this was a fine sheet of water, overhung with shady tea-trees, Casuarinas, and Pandanus, which made this crossing place extremely lovely. My grief at having lost an excellent horse which I had ridden for the greatest part of the journey, was increased by now knowing that one mile more travelling would have saved him to me. The northern banks of the river were at first open: but they soon became bounded either by isolated, or chains of, rocky hills. These hills separated the valley of the river from an open well grassed, but extremely stony back country; from which creeks carried the water down to the river, through gaps and openings between the hills. To the northward of this back country, other ranges ran parallel to those along the river, from northwest by west to south-east by east, and shorter ranges joined them occasionally. The whole country was composed of sandstone and indurated clay, with very distinct stratification. The layers of clay were white, grey, or slate-coloured; with many shining leaflets of mica. The days were very hot; the east-breeze very strong during the afternoon, and particularly towards sunset; the nights were warm, clear, and without dew.
