was passed for 30 miles to the northward; the effects of violent floods were visible, but it did not bear the character of a stream rising at any great distance inland, nor did the nature of the gravel and sand brought down by it indicate a rich soil on its upper portion, as I did not see anything besides fragments of siliceous rock and garnet sand.  The valley through which it ran appeared to be five or six miles wide, extending twenty miles to the eastward, backed by sandy plains on both sides; a few patches of grass appeared in the lower parts of the valley; westward it seemed to contract and turn to the south-west, flanked by steep flat-topped hills of sandstone, resting on granite rock.  Continuing north-north-east up a small valley, we passed through wattle thickets till 1.40 p.m., when we again ascended the level sandy tableland or plains, and changed the course to the north; the scrub increased in density as we proceeded.  At 4.25 halted for the night in a patch of good grass, where the thicket had been burnt off by the native fires; the sandy nature of the soil rendered the search for water unsuccessful; we therefore contended ourselves with the allowance of one pint each.

Left the bivouac at 7.15 a.m.; course north; the country more open; 9.25 came on a large native well of good water in a slight hollow trending westward; having watered the horses and filled the kegs, continued our journey over sandy plains, covered with short coarse scrub; many hummocks of loose sand, covered partially with scrub, lay on each side of our track.  At noon passed the last sandy ridge; before us lay an immense plain, covered with thickets, and not a hill or valley could be observed—­the country seemed to settle into one vast level of dense and almost impenetrable scrub or thicket.  At 1 p.m. entered it, and continued our route through it; although the bush-fires, which had burnt some large patches, greatly assisted us; 4.15 not finding any grass, we steered west, but at 5.15 were compelled to halt for the night in a dense thicket, without a single blade of grass or even scrub of any kind which could afford food for the horses; water it was hopeless to look for; and after a supper of raw bacon, damper, and a pint of water each, we retired to rest.

Waterless country and dense scrub north of Murchison river.

27th September.

At 7.0 a.m. set out on a north course; at 8.5, finding the thicket almost impassable, I ascended a cypress-tree, where a most cheerless view met my sight to the north, east, and west; not a break was visible—­nothing but thicket in all directions, with scarcely an undulation of any kind; the view to the north-west was most extensive—­nearly twenty miles of thicket could be seen, with a surface as level as the sea.  Not considering it prudent to proceed onwards, the thicket being too dense to advance without the greatest difficulty, the saddle-bags
