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. 7th June. 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.
