left there were to fall back to the Oakover; I therefore directed Mr. Brown, who was somewhat fresher than myself, to push on for the camp and to bring out fresh horses with water, while Mr. Harding and myself would do our best to bring on any straggling horses that could not keep up with him.  By dark we had succeeded in reaching to within nine miles of the depot, finding unmistakable evidence towards evening of the condition to which the horses taken on by Mr. Brown were reduced, by the saddles, guns, hobbles, and even bridles, scattered along the line of march, which had been taken off to enable them to go on a few miles further.

Effects of want of water.

9th September.

At dawn Mr. Harding and myself got up from our beds of sand stiff and giddy, but much refreshed by the cold night air.  In four or five miles we met Mr. Brown with fresh horses and a supply of water, having succeeded in reaching the depot at 8 p.m. the night before, with only one horse.  We were now enabled to proceed with the tracking up of the horses left overnight, which, after resting some hours, had commenced to ramble in search of water; Mr. Brown returning on our route and recovering the saddles and firearms left the previous evening, the stores abandoned the day before being too far off to attempt their recovery.  By 8.30 p.m. we had all returned to the depot, having tracked up the three missing horses, the two left at the furthest point being too distant to carry relief to without incurring the risk of further loss.  I cannot omit to remark the singular effects of excessive thirst upon the eyes of the horses; they absolutely sunk into their heads until there was a hollow of sufficient depth to entirely bury the thumb in, and there was an appearance as though the whole of the head had shrunk with them, producing a very unpleasant and ghastly expression.  Depot camp.

We were only able to move the camp a mile to another waterhole, for the sake of a little better feed.  Bivouac.

Commence return journey.

On taking into consideration the reduced number and strength of our horses, it was quite evident that we had but little prospect of being able to cross the tract of dry sandy country that had already occasioned us so much loss and trouble; yet there were many reasons to stimulate us to make the attempt.  Not only had we now attained to within a very few miles of the longitude in which, from various geographical data, there are just grounds for believing that a large river may be found to exist, draining Central Australia, but the character of the country appeared strongly to indicate the vicinity of such a feature; added to which, the gradual decline in the elevation of the country, notwithstanding our increasing distance from the coast, tended towards the same conclusion.  Nor should we omit the strong evidences that the remarkable
