Penetrating the scrub in a southerly direction we soon came upon open ground, the surface of which consisted of firm clay. The river was close on our right until, at about six miles forward, it turned off to the westward. We pursued our journey over plains and through scrubs, first south-west, then west, and finally north-west, encamping at last, after a journey of fourteen miles, where the bend of the river was still 1 1/2 miles to the north of us. We had crossed at 12 miles the dry bed of a river which was five chains wide, and whose course was to the north. In it were several natives' canoes, and on its banks grew large rivergum-trees, or eucalypti. The course of this tributary (which probably included that which we had seen previously) and the change in the direction of the main stream, which trended now so much towards the west, made it still possible that a range separated it from the Murray. There was now less of the extensive plains of bare soft earth, and more of the firm clay, with small rough gumtrees. Few bushes of the genus acacia were now to be seen, but the minor vegetation appeared to be much the same as on the upper parts. As great a paucity of grass also prevailed here, except on the riverbank, and as great an abundance of the same atriplex and cucurbitaceous plants as I had noticed elsewhere. A RANGE DISCOVERED BY REFRACTION. July 6. From a tree at our camp a range was observed in the south-west, having become visible from refraction, and this rendered it still more probable that the river would continue its westerly course. I soon found it necessary however to travel south-west in order to avoid it, and having yesterday exceeded our usual distance I halted at the end of 8 1/4 miles; the river being then distant about two miles to the north. From a bare hill beyond this camp I could see nothing southward, except a perfectly level horizon of low bushes, the country being nevertheless full of hollows, in which grew trees of large dimensions. The river line was so sunk among these hollows that I could trace it for only a short distance, and there it bore about west-north-west. The banks of the river opposite to our camp of yesterday were of rather different character from those which we had seen above. The slopes towards the stream commenced some hundred yards from it, and they were grassy and gently inclined on each side, so that our carts might have passed easily. We saw enormous trees by the riverside, and the scenery was altogether fine. The stream glided along at the rate of two miles per hour over a rock of ferruginous sandstone containing nodules of ironstone. DANCE OF NATIVES.
