Resumed our journey at 7.10 a.m., and, following the right bank of the river nearly west through the gorge, at 9.0 entered an open valley, through which the river came from the south-west; but at 10.0 we entered a second defile, which, from the inclined strata of sandstone, was almost impassable for the horses. In crossing some soft ground between the rocks one of the horses fell on a sharp stump, and was deeply wounded in the belly. The wound was sewn up; but the injury was so severe that the horse died in the night. Having extricated ourselves from this ravine, we encamped at the foot of a sandstone hill, the strata of which dipped 60 degrees to the south-west. Ascending the hill, which was about 300 feet high, the country appeared more level to the south, rising into sandstone ranges at ten miles distance. The course of the river was from west-south-west, the channel being bounded by sandstone cliffs 100 to 200 feet high. The general aspect of the country was wretched in the extreme, as little besides a few small gum-trees and triodia clothed the rugged surface of the red sandstone. The weather continues fine, with only an occasional cloud or flash of lightning in the early part of the night. The temperature is increasing, being 104 degrees at 1.0 p.m. Some catfish and a small tortoise were caught in the river. 22nd January. At 7.0 a.m. continued our route up the river; but, to avoid the deep ravines on its banks, made a sweep to the south, and at noon encamped in a grassy flat on the bank of the river. The country traversed was very barren and rocky, and the horses had great difficulty in crossing the deep ravines; many of their shoes were torn from their feet during the day's journey. The highest ridge crossed was 500 feet above the bed of the river, the height of which is approximately 500 feet above the sea-level, and thus the general level of the tableland may be considered to be 1000 feet above the sea. The general course of the river being from the west, it appears advisable to reconnoitre the country to the south. Latitude by Capella 16 degrees 47 minutes 58 seconds. RECONNOITRE TO THE SOUTH. 23rd January.
