July 27.--I stopped at this camp to allow our cattle to recover from their fatigue; intending afterwards to proceed up the river until I came into the zone of fresh water, which we had left, and then to continue my course to the west and north-west. During our stay in this place, Mr. Calvert found a piece of pack canvass, rolled round some utensils of the natives.

July 28.--We travelled about ten miles south by east; but were soon compelled by the salt-water creeks to leave the river, which seemed to come from south-south-east. We crossed several mangrove creeks, one of which contained a weir formed by many rows of dry sticks. These creeks were too boggy to be forded in any part where the tide reached, and we had to follow them up for several miles, until their beds divided into lagoons. Here the drooping tea-tree re-appeared, which I considered to indicate the presence of fresh water, at least for a part of the year. I found them, however, at times, on salt-water rivers, not on the level of the salt water, but high on the banks within the reach of the freshes during the rainy season. In turning again towards the river, we crossed a large plain, from which pillars of smoke were seen rising above the green belt of raspberry-jam trees which covered the approaches to the river. After passing some forest of Moreton Bay ash, bloodwood, clustered box, Acacia (Inga moniliformis), and a few Bauhinias, we came to another salt-water creek, with a sandy bed and deposits of fine salt. Very narrow flats extended along both sides of the creek, and rose by water-torn slopes into large treeless plains. The slopes were, as usual, covered with raspberry-jam trees. I saw smoke to the south-ward, and, on proceeding towards it, we came to a fine lagoon of fresh water in the bed of the creek.

July 29.--We travelled about five miles and a half south-south-east up the creek, and encamped in latitude 18 degrees 2 minutes. The character of the country was the same. When about two miles from our last camp, we came upon a tribe of natives fishing in a water-hole, near which a considerable quantity of large and small fish was heaped. The men made a tremendous noise, which frightened our bullocks, and hastened to the place where their gins were. The latter, among whom was a remarkably tall one, decamped at our approach. A fine shell of Dolium was in their camp, which we passed through. After we had passed by, the natives followed us; upon which I returned towards them, and hung a nose ring on the branch of a small tree. This sign of friendly disposition on my side, emboldened them to approach me and demand a parley. I, therefore, dismounted, and, accompanied by Charley, divided some empty tin canisters among them, with which they seemed highly satisfied. They were altogether fine men. Three or four old men with grey beards were amongst them; and they introduced a young handsome lad to me, with a net on his head and a quill through his nose, calling him "Yappar." He was probably a youth of the Yappar tribe who had been sent forward as a messenger to inform them of our having passed that country. Seeing my watch, they pointed to the sun; and appeared to be well acquainted with the use of my gun.

Further up the creek, we again saw some storied gunyas of the natives.

July 30.--We travelled about ten miles west by south, over an immense plain, with here and there a solitary tree, or a small patch of forest. It was full of melon-holes, and much resembled the plains of the Condamine. Salicornia and Binoe's Trichinium were wanting. At the west side of the plain, a green belt of forest stretched from north to south. Before we entered into it, and into the valley of the creek, along which it extended, we passed some open forest of stunted silver-leaved Ironbark. On the slopes of the plains we met, as usual, the raspberry-jam tree thickets, and on the flats and hollows along the creek, the clustered box; whilst, on the banks of the creek, grew the broad-leaved Terminalia and Acacia (Inga moniliformis). Following the creek up about half a mile, we found a fine rocky water-hole. The rock was a clayey Ironstone.

When entering upon the plain in the morning, we saw two emus on a patch of burnt grass. Brown and Charley gave chase to them; but Brown's horse stumbled and threw him, and unfortunately broke the stock of the double barrelled fowling piece, and bent the barrels. Spring took hold of the emu, which dragged him to the lagoon we had left, pursued by Charley on foot. The emu plunged into the water, and, having given Spring and Charley a good ducking, made its escape, notwithstanding its lacerated thigh. Three harlequin pigeons, and six rose-breasted cockatoos (Cocatua Eos, GOULD.), were shot on the plains.

The weather was delightful; a fine breeze from the east cooled the air.

July 31.--We made about ten miles due west, the latitude of our camp being 18 degrees 6 minutes 42 seconds. After passing some Ironstone ridges, covered with stunted silver-leaved Ironbark, we entered upon a large plain, from which we saw some low ranges to the south, and smoke to the W. 20 degrees S. I followed this course about seven miles; but the smoke was still very distant, and, perceiving a belt of forest to the westward, I took that direction, passed the head of a small creek which went to the southward, crossed some box forest and Ironbark ridges, and came into an open country, with alternating plains and ridges, which, even at the present season, was very pretty, and must, when clothed in the garments of Spring, be very beautiful. The creek which we had met at the east side of the forest, had swept round the ridges, and was now again before us, pursuing a north-west course. A fine plain extended along it, on which I observed Acacia Farnesiana of Darling Downs, the grass of the Isaacs, and several grasses of the Suttor. The holes of the creek were shaded by large Terminalias, and by a white gum, with slightly drooping foliage of a pleasing green colour. We followed the creek down, and soon came again to Ironstone ridges.

I had sent Charley forward to look for water, and, when he joined us again, he told me that there was a water-hole, but that natives, for the greater part gins, were encamped on it. I could not help taking possession of it, as there were none besides, to our knowledge; and our bullocks and horses were fatigued by a long stage. I, therefore, rode up to it alone; the gins had decamped, but a little urchin remained, who was probably asleep when his mother went. He cried bitterly, as he made his way through the high grass, probably in search for his mother. Thinking it prudent to tie an iron ring to his neck, that his parents might see we were peaceably inclined, I caught the little fellow, who threw his stick at me, and defended himself most manfully when I laid hold of him. Having dismissed him with an angry slap on his fat little posteriors, he walked away crying, but keeping hold of the iron ring: his mother came down from the ridge to meet him, laughing loud, and cheering with jokes.

I observed ironstone pebbles, and large pieces of a fine grained flaggy sandstone on the first plains we crossed; the sandstone was excellent to sharpen our knives.
