Oct. 13.--We travelled about sixteen miles to the southward, to lat. 15 degrees 29 minutes 10 seconds, following the river, and heading several salt water creeks, which prolonged our journey very much. Stony hills and ranges frequently approached the river, and rendered our travelling difficult and fatiguing. They were composed of baked sandstone, and white and blue indurated clay, the strata of which dipped at a very small angle to the southward, and the strike from east to west. The flats between the ranges, and along the river and creeks, were openly timbered and well grassed; and, at the head of a salt-water creek, we found deep ponds of constant water covered with Nymphaeas, and surrounded with Typhas and drooping tea-trees. Towards the end of the stage, where the high rocky hills formed deep declivities into the river, we had to ascend them, and to travel along their summits. A good sized creek joined the river at their southern slopes, which, though salt below, contained some good pools of fresh water higher up. To the southward of this creek, there were four very remarkable flat-topped cones of sandstone, which appeared like a plateau cut into four detached masses. These I called the "Four Archers," in honour of my excellent hosts Messrs. David, Charles, John, and Thomas Archer of Moreton Bay. From the eastern one, I enjoyed a fine view, and distinguished distant ranges broken by a gap to the southward, and detached long-stretched ridges to the westward.

I went with Charley to examine the river, in order to find a fording place, in which we succeeded at about four miles south-west from our camp, in lat. 15 degrees 30 minutes 31 seconds; where a stony bar crossed the salt water, leaving a small channel in which the tide formed a shallow stream. The bed of the river became very broad and sandy, covered with shrubs like those of the Lynd and most of the other rivers we had passed.

Oct. 14.--We crossed the river, and travelled about ten miles north-west, over a succession of stony ridges, separated by fine open tea-tree and box flats. Some fine shallow sandy watercourses, quite dry, went down to the north by east. At the end of the stage, the uniform colour of the country was interrupted by the green line of a river-bed, so pleasing and so refreshing to the eye, with the rich verdure of its drooping tea-trees and myrtles, interspersed with the silver leaves of Acacia neurocarpa and Grevillea chrysodendron. The river was formed by two broad sandy beds, separated by a high bergue, and was full 700 yards from bank to bank. It contained large detached water-pools fringed with Pandanus, which were very probably connected by a stream filtering through the sands, I called it the "Wickham," in honour of Captain Wickham, R.N. of Moreton Bay, who had recently commanded a survey of the north-west coast of New Holland, in H.M.S. Beagle.

The red wallabi (Halmaturus agilis, GOULD) was very numerous along the gullies of the river: and we started a flock of red foresters (Osphranter Antilopinus, GOULD) out of a patch of scrub on the brow of a stony hill. Charley and Brown, accompanied by Spring, pursued them, and killed a fine young male. I had promised my companions that, whenever a kangaroo was caught again, it should be roasted whole, whatever its size might be. We had consequently a roasted Red Forester for supper, and we never rolled ourselves up in our blankets more satisfied with a repast.

Brown found a Eugenia, with large white blossoms and large coriaceous oblong lanceolate shining leaves; it was a tree of thirty or forty feet high, with a grey bark, and a good hard wood. It was growing at the upper part of the creek on which we were encamped last night. Its fruit was two inches in diameter, with longitudinal ribs, scarlet red, and very eatable when dropt from the tree, but when gathered on the tree, it had an aromatic pungency. This tree was very common along the well watered creeks of Arnheim's Land; particularly along the South Alligator River, and at Raffles Bay. Brown brought from the same locality a Melastoma, which, according to him, was a shrub, three or four feet high.

Oct. 15.--We continued our journey in a north-west direction. The first five or six miles was over a succession of very lightly timbered box-flats, alternating with small plains. They were bounded by scrubs and ranges, which we crossed, and from the top of one obtained the view of a remarkable system of parallel ranges, all steep mountain walls of a white colour indicating the nature of their rock, and separated from each other by perfectly level flats covered with broad leaved tea-tree forest. At their foot a richer tree vegetation existed, principally composed of the leguminous Ironbark, Blood-wood, and Pandanus. The darker verdure of these trees, which we also observed at the foot of the most distant range, made us believe that a river was near it. After travelling about five miles over a flat, we crossed a broad sandy creek, which we did not follow, although beaten foot-paths of the natives led down it, as we firmly believed that a river was before us. At five miles farther, we came to the foot of the range, which rose suddenly from the level country, and, although a small watercourse existed in the tea-tree flat, our anticipated river proved to be like the Dutchman's "Cape Fly-away." In ascending the range, our poor bullocks suffered severely, and, when we reached the summit, they stood panting with their tongues hanging out of their mouths; I therefore halted a short time, to allow them to recover. The east slopes of all these ranges were steep, but to the north-west they were very gentle, and covered with stringy-bark forest. A long succession of similar ranges was seen to the north-west. A small watercourse brought us to a creek containing large but dry water-holes. Finding that it turned to the eastward, round the range we had just crossed, and that it almost disappeared in the scrubby tea-tree flats, we turned to the northward, passed several more ridges, and encamped long after sunset, near a dry but promising creek, without water. I immediately sent Mr. Calvert and Charley down the creek, in search of water, and they returned, towards midnight, with the welcome intelligence that they had found some fine pools.

I had been absent during the latter part of the stage, and most unfortunately our kangaroo dog had been left behind, whereby this most valuable animal was lost. He had been the means of our obtaining so much, and indeed the greatest part of our game, that his loss was severely felt by us.

Our lat. was 15 degrees 10 minutes.

Oct. 16.--We travelled down to the water, about four miles north-east along the creek, which was covered with Cypress pine thickets, and tea-tree scrub. Mr. Calvert and Charley returned on our tracks to endeavour to recover our poor dog. They found him almost dead,--stretched out in the deep cattle track, which he seemed not to have quitted, even to find a shady place. They brought him to the camp; and I put his whole body, with the exception of his head, under water, and bled him; he lived six hours longer, when he began to bark, as if raving, and to move his legs slightly, as dogs do when dreaming. It seemed that he died of inflammation of the brain. If we become naturally fond of animals which share with us the comforts of life, and become the cheerful companions of our leisure hours, our attachment becomes still greater when they not only share in our sufferings, but aid greatly to alleviate them. The little world of animated beings, with which we moved on, was constantly before our eyes; and each individual the constant object of our attention. We became so familiar with every one of them, that the slightest change in their walk, or in their looks was readily observed; and the state of their health anxiously interpreted. Every bullock, every horse, had its peculiar character, its well defined individuality, which formed the frequent topic of our conversation, in which we all most willingly joined, because every one was equally interested. My readers will, therefore, easily understand my deep distress when I saw myself, on recent occasions, compelled to kill two of our favourite bullocks long before their time; and when our poor dog died, which we all had fondly hoped to bring to the end of our journey. Brown had, either by accident, or influenced by an unconscious feeling of melancholy, fallen into the habit of almost constantly whistling and humming the soldier's death march, which had such a singularly depressing effect on my feelings, that I was frequently constrained to request him to change his tune.

Oct. 17.--We travelled about eighteen miles N. N. W. over an undulating country, in which Cypress-pine thickets alternated with scrubby stringy-bark forest, and some tea-tree flats. After seven miles, we crossed a large dry creek, which went to the eastward; and, eight miles further, we entered upon a fine box-flat, with hills to the north and north-west. We followed a very promising Pandanus creek, in which the presence of Typha (flag, or bulrush) and a new species of Sesbania indicated the recent presence of water. Mr. Roper having ascended one of the hills, and seen a green valley with a rich vegetation about three miles to the northward, we in consequence left the creek, which turned to the eastward; and, after passing several miles of most wretched scrub, came into an open country, with scattered groves of trees. As the sun was setting, I resolved upon encamping in an open plain, although without water, except what we carried in our large stew-pot. Charley, who had been sent forward, had not yet joined us; I, therefore, ordered two guns to be fired, to let him know where we were; he immediately answered us from a short distance, where he lighted up a cheerful fire. After some time, during which misfortune and carelessness had played us the trick of upsetting our waterpot, Charley arrived with the welcome news that he had found some water-holes in a small creek; we therefore, at moonrise, again saddled our tired animals, and repaired thither.
