At 6.50 a.m. resumed a south-east course, traversing a broken country with limestone, chert, sandstone, and trap hills, deeply cut by dry watercourses.  The grass was abundant and good, though triodia appeared on the higher ridges; at 7.0 crossed a small river, with fine permanent pools of water in a rocky bed ten to thirty yards wide.  The floods rise twenty feet, and extend over a breadth of 70 to 100 yards.  It is the largest stream-bed crossed since leaving the river, and may possibly drain the country to a distance of sixty miles to the southward.  At 1.25 camped on a small creek trending to the north-north-east, in which were pools twenty yards long and five feet deep.

Native fishing nets.

Left the camp at 7.0 a.m. and continued a south-easterly course, crossing a succession of sandy valleys and broken sandstone hills; the strata horizontal, and lamina dipping to the north and east generally, but sometimes in the opposite direction; the soil poor and sandy, producing little besides white-gum and triodia.  At noon ascended a high ridge, from which we saw a broad valley to the south-east, beyond which was a range of flat-topped hills terminating abruptly at the northern end, which bore east by north.  Descending by a rocky ravine, at 1.30 p.m. reached a fine creek, on which we camped.  This creek had deep pools of water fifty yards wide; but the steep rocky character of its banks caused the channel to appear larger than if it had been in a more level country.  Under some large rocks Dean found a fishing-net made neatly of twisted bark, the mesh one and a half inch, the length perhaps thirty feet; some fishing spears showed the marks of iron tools.  The rocks in this part of the country often contain angular fragments of the lower strata; thus the limestone includes fragments of chert and jasper, and the sandstone pieces of limestone, but I could not detect either granite, quartz, or slate.

At 6.20 a.m. we were again in the saddle, and steered south-east across very rocky hills till 8.0, when we entered a fine valley with low hills of limestone and trap, well grassed and thinly wooded with box-trees and acacia; at 10.0 ascended a rough sandstone range with white-gum, acacia, and triodia; at 11.0 again descended into a valley bounded by sandstone cliffs on the northern side, and camped at a fine pool of water in a small creek at 12.5.  Several trees near this pool of water had been marked by the blacks, the bark having been removed, the wood was painted yellow with brown spots at regular intervals, and vertical waved lines in black.  It is evident from the outline of the hills that we are travelling on the
