country to the eastward rose to a considerable height above its summit, which, by comparisons from the aneroid barometer, would give not less than 4000 feet for the elevation of those ranges.  Having completed my observations, I descended the hill with somewhat greater speed than it took to climb it, and was met at the foot by Messrs. Brown and Harding, who had waited for me with a horse.  In less than an hour we overtook the rest of the party at Camp 22, when the additional horses at once drank up all the remaining water left in the rocks; resting, therefore, less than an hour, we moved on, taking a north course, over a very rocky but highly fertile country of trap formation, the grass just now being much dried up.  At sundown we halted in an open grassy flat, on which no water could be found, although it is probable there is plenty in the vicinity, as emus and cockatoos were numerous; one of the former walked boldly up to the horses, and was fired at, but without effect.  Camp 35.

Open grassy plains.  Pass hamersley range.

4th July.

Travelling at a rapid pace on an average north-east course for upwards of twenty miles, over plains mostly of rich loam, well grassed, and extending to the southern foot of the Hamersley Range, we came upon a low range of sandstone hills, covered with acacia bushes and triodia, extending for three or four miles, when we again emerged on open plains, in which was found a deep channel, thirty yards wide, containing pools of rainwater retained in the clay.  The amount of fine pasture country passed over during the day could not be less than 200,000 acres; and although we had not time to go in search for it, I have no doubt that abundance of water will be found in the deep gorges of the range skirting the plain.  This tract of country is, I imagine, well suited for the growth of either cotton or sugar, as it is apparently well-irrigated during the summer months, and the soil is remarkably rich and strong, while its limits to the westward are at present unknown, and most probably continues to skirt the hills for at least thirty or forty miles.  Halted at the waterholes about four miles to the west of the pass through the Hamersley Range.  Camp 36.

5th July.

Two hours brought us to the head of the pass, which we entered by a ravine a little more to the northward than on our outward route, and by so doing saved a preliminary ascent of nearly 200 feet, and a similar amount of descent, making a very successful passage through the range without experiencing the same difficulties we had formerly met with, and by 3 p.m. found ourselves once more in the open grassy country that forms the Chichester Downs.  At 6 p.m. encamped in an open flat without water.  Camp 37.

Proceed towards the coast.

6th July.

Started at 7.30 a.m., and in an hour came upon a pool of water in one of the numerous channels into which the Fortescue is here divided, and at seven miles struck the bulrush spring passed on the 11th June.  From this the river was followed down for thirteen miles, through grassy clay plains, thinly timbered with white-gum.  Encamped on a pool, in latitude 21 degrees 53 minutes 4 seconds, about five miles north of a very remarkable bold projection of the Hamersley Range.  Camp 38.
