Having marked a large double-stemmed gum-tree with NAE and the date, we made a start up the river, but at about a mile found the valley narrow in until the channel of the river, which was here full of water, was walled in on both banks by perpendicular cliffs, from which we were compelled to turn back nearly to our last night's camp. During the last two days we had caught an occasional glimpse of an elevated range of hills extending for many miles parallel to the river and about ten miles to the southward, which rendered it probable that some change would now be found in the character of the back country, enabling us to travel without being so frequently retarded by the rocks and bends of the river. A suitable spot was accordingly selected for ascending out of the valley, which was accomplished with some difficulty, when the country was observed to be intersected for many miles by deep ravines, terminating, however, to the south in a level plain, extending to the base of the range already referred to. After four hours' heavy toiling, we at length reached the summit of the plain, water having been found in one of the rocky gullies by the way. For the first half-mile, on entering the plain or tableland, the ground was stony and covered with stunted acacia, but it very quickly changed into a rich clayey loam, yielding a splendid crop of kangaroo and other grasses, melons, and small white convolvulus, yielding a round black seed the size of a pea, which we found scattered over nearly the whole surface of the plain for miles together. In the lower parts of the flat rainwater appeared to have remained in shallow clay-pans until very recently, killing much of the grass, which was replaced by atriplex bushes. As we approached the foot of the range the ground became stony and covered with triodia; good grass was still, however, to be found in the ravines leading out of the hills, and as our object was now to shape a course to the southward, we followed up one of the most promising valleys, in the hope that it might lead us through the range; we were, however, disappointed in finding that, after pushing some distance up very steep and rocky passes, they all terminated in cliffs of horizontal sandstone, running in parallel bands one above another to the height of 500 or 600 feet, and frequently extending without a break for ten or fifteen miles along the face of the range. The horses being much fatigued by the climb from the valley of the river, we encamped at 3.10 p.m., within the hills, and without water. Camp 12.
FINE GRASSY PLAIN. FORTESCUE RIVER.
6th June.
A light drizzling rain came on early in the morning, but not enough to supply the horses, who rambled so far during the night in search of it that it was noon before they were all collected. Quitting the range, which had been named after one of the most liberal promoters of the expedition, Hamersley Range, we took a north-east course, crossing over twelve or fourteen miles of beautiful open grassy plain, in many parts the kangaroo-grass reaching above the horses' backs; the soil being of the richest clay-loam, occasionally containing beds of singular fragments of opaline rocks, resembling ancient lava. By 5.30 p.m. we reached the river again, several miles above the deep glen that had checked our course on the 5th. The valley having again opened out, gave us easy access to its banks, which were here a rich black peat soil, containing numerous springs. Here was first observed a very handsome fan-palm, growing in topes, some of them attaining to the height of forty feet and twenty inches diameter, the leaves measuring eight to ten feet in length. The river had again opened into deep reaches of water, and contained abundance of fish resembling cobblers, weighing four and five pounds each. The whole character of the country was evidently changing for the better; and as I have no doubt that at no distant period it will become a rich and thriving settlement, I named the river the Fortescue, after the Under Secretary of State for the Colonies, under whose auspices the expedition took its origin, and the large expanse of fertile plain that lies between the river and the Hamersley Range, Chichester Downs.

A quarter of a mile up the river brought us to a fine tributary from the south, running strong enough to supply a large mill. This had to be traced up for two miles before we could find a ford; it was found to take its rise in several deep pools, fed by springs issuing out of the plains crossed yesterday. Some powerful springs were also observed to flow into the river from the northward, through a dense forest of melaleuca, with a rank undergrowth of canes, flags, etc. At five miles the river again presented a wide reach of water several miles in length, after which it all at once broke up into numerous channels, wandering through a forest of white-gum, well grassed, the soil being highly fertile. Owing to my having been accidentally trodden upon by one of the horses, we were obliged to encamp early, having only made about twelve miles. Camp 14.

8th June.
Following up the channel upon which we had encamped, in about an hour it was lost in open grassy plains, which we continued to traverse until noon, when we struck on a well-defined stream-bed, which had branched off a mile or two south of last night's camp. Grass and water being abundant, we halted till 2, when we resumed an easterly route to 5.30, over rather stony plains, yielding triodia. Encamped after dark without water or feed, tying the horses up short to prevent their rambling, having accomplished about twenty miles in an east-south-east direction during the day. Camp 12.
