A little below the hills under which we had stopped, the country again assumed a level. A line of cliffs, of from two to three hundred feet in height, flanked the river, first on one side and then on the other, varying in length from a quarter of a mile to a mile. They rose perpendicularly from the water, and were of a bright yellow colour, rendered still more vivid occasionally by the sun shining full upon them. The summits of these cliffs were as even as if they had been built by an architect; and from their very edge, the country back from the stream was of an uniform level, and was partly plain, and partly clothed by brush. The soil upon this plateau, or table land, was sandy, and it was as barren and unproductive as the worst of the country we had passed through. On the other hand, the alluvial flats on the river increased in size, and were less subject to flood; and the river lost much of its sandy bed, and its current was greatly diminished in strength.

NATIVE CHARACTER.

It blew so fresh, during the greater part of the day, from the westward, that we had great difficulty in pulling against the breeze. The determined N.W. course the river kept, made me doubt the correctness of the story of the little old black; yet there was an openness of manner about him, and a clearness of description, that did not appear like fabrication. He pointed to the S.S.W. when he left us, as the direction in which he would again join us, thus confirming, without any apparent intention, what he had stated with regard to the southerly course the river was about to take. Among the natives who were with him, there was another man of very different manners and appearance. Our friend was small in stature, had piercing grey eyes, and was as quick as lightning in his movements The other was tall, and grey headed; anxious, yet unobtrusive; and confident, without the least mixture of boldness. The study of the human character on many occasions similar to this, during our intercourse with these people, rude and uncivilized as they were, was not only pleasing, but instructive. We found that the individuals of a tribe partook of one general character, and that the whole of the tribe were either decidedly quiet, or as decidedly disorderly. The whole of the blacks left us when we started, but we had not gone very far, when the individual I have described brought his family, consisting of about fifteen persons. We were going down a part of the river in which there was a very slight fall. The natives were posted under some blue-gum trees, upon the right bank, and there was a broad shoal of sand immediately to our left. They walked over to this shoal, to receive some little presents, but did not follow when we continued our journey.

TAKE BEARINGS.

During the whole of the day the river ran to the N.W. We stopped for the night under some cliffs, similar to those we had already passed, but somewhat higher. From their summit, mountains were visible to the N.W., but at a great distance from us. I doubted not that they were at the head of the southern gulfs; or of one of them, at all events. Our observations placed us in 34 degrees 08 minutes south of lat., and in long. 139 degrees 41 minutes 15 seconds; we were consequently nearly seventy miles from Spencer's Gulf, in a direct line, and I should have given that as the distance the hills appeared to be from us. They bore as follows:—

Lofty round mountain, S. 127 degrees W.
Mountain scarcely visible, S. 128 degrees W.
Northern extremity of a broken range, S. 102 degrees W.
Southern extremity scarcely visible, S. 58 degrees W.

The country between the river and these ranges appeared to be very low, and darkly wooded: that to the N.E. was more open. The summit of the cliff did not form any table-land, but it dipped almost immediately to the westward, and the country, although, as I have already remarked, it was depressed, and undulated.

I walked to some distance from the river, across a valley, and started several kangaroos; but I was quite alone, and could not, therefore, secure one of them. Had the dogs been near, we should have had a fine feast. The soil of the interior still continued sandy, but there was a kind of short grass mixed with the salsolaceous plants upon it, that indicated, as I thought, a change for the better in the vegetation; and the circumstance of there being kangaroos in the valleys to the westward was also a favourable sign.

FEAST ON A TORTOISE.

Beneath the cliffs hereabouts, the river was extremely broad and deep. My servant thought it a good place for fishing and accordingly set a night-line, one end of which he fastened to the bough of a tree. During the night, being on guard, he saw a small tortoise floating on the water, so near that he struck it a violent blow with a large stick, upon which it dived: to his surprise, however, in the morning, he found that it had taken the bait, and was fast to the line. On examining it, the shell proved to be cracked, so that the blow must have been a severe one. It was the largest we had ever seen, and made an excellent dish. The flesh was beautifully white, nor could anything, especially under our circumstances, have been more tempting than it was when cooked; yet M'Leay would not partake of it.
