At 6.45 a.m., proceeding west, ascended a granite hill, near the top of which we found a native well, where we halted at 7.30. Having watered the horses and breakfasted, at 9.30 resumed our journey over granite hills, covered with brushwood and cypress with a few grassy patches; at 11.10 passed a native well; altered the course to west-south-west, crossing three small watercourses trending north-west; and at 1.15 p.m. halted at the foot of a bare granite hill, on the top of which there was a fine pool of rainwater in a shallow basin of the rock. Latitude 28 degrees 50 minutes 51 seconds; longitude 116 degrees 29 minutes. 7th September. Started at 7.15 a.m. on a course 255 degrees through acacia thickets; at 10.5 crossed a narrow strip of salt marsh, which spread out into dry salt lakes to the south; after this the country was grassy till 11.30, when we entered a dense thicket of acacia, melaleuca, cypress, and eucalypti, the ground gradually rising till 4.0 p.m., and then descending till 5.25, when we crossed a small dry watercourse trending south; at 6.10 bivouacked in a gum forest without water or grass, though a large flight of white cockatoos which roosted near seemed to indicate that water was not far distant. Latitude 28 degrees 58 minutes 14 seconds; longitude 116 degrees 6 minutes. 8th September. Leaving the bivouac at 7.0 am steered west; at 7.20 came to a grassy granite hill, then west-north-west to another hill, where we halted for half an hour to look for water, but being unsuccessful, again resumed a westerly course through acacia thickets, alternating with grassy gum forest, till noon, when the soil changed from a red loam to ironstone gravel; grass disappeared and was replaced by scrub; the country was much broken and continued to rise till 4.0 p.m., when it began to descend rapidly till 4.30, when we came to a small watercourse trending south; following it down for half a mile, found a small pool of water and some grass, and halted for the night, this being the only water seen for nearly fifty miles. Latitude 28 degrees 58 minutes 50 seconds; longitude 115 degrees 45 minutes. DISCOVER TWO SEAMS OF COAL. 9th September.
