Nov. 25.--We travelled about seven miles and a half N.W. by W., to lat. 13 degrees 0 minutes 56 seconds. I intended to follow the sandy bergue of the river, but a dense Pandanus brush soon compelled us to return, and to head several grassy and sedgy swamps like those we passed on the last stage. Chains of small water-holes, and Nymphaea ponds, ran parallel to the river; and very extensive swamps filled the intervals between rather densely wooded ironstone ridges, which seemed to be spurs of a more hilly country, protruding into the valley of the river. Some of these swamps were dry, and had a sound bottom, allowing our cattle to pass without difficulty. Others, however, were exceedingly boggy, and dangerous for both horse and man; for Charley was almost suffocated in the mud, in attempting to procure a goose he had shot. The swamps narrowed towards the river, and formed large and frequently rocky water-holes, in a well defined channel, which, however, became broad and deep where it communicated with the river, and which in many places rivalled it in size. A belt of drooping tea-trees surrounded the swamps, whilst their outlets were densely fringed with Pandanus. The Livistona palm and Cochlospermum gossypium grew on the ridges; the tea-tree, the stringy-bark, the leguminous Ironbark and Eugenia were useful timber. The whole country was most magnificently grassed.

A Porphyritic sienite cropped out at the head of the first swamp, about a mile from our last camp.

We had cut our rifle balls into slugs, with which Charley and Brown shot three geese (Anseranus melanoleuca, GOULD).

A low range was seen at the south-east end of the large swamp on which we encamped.

Nov. 26.--We travelled about nine miles and a half N.N.W. to lat. 12 degrees 51 minutes 56 seconds. After having once more seen the river, where it was joined by the broad outlet of a swamp, I turned to the northward, and passed over closely-wooded and scrubby ridges of ironstone and conglomerate, with pebbles and pieces of quartz covering the ground. Livistona inermis, R. Br. formed small groves; and Pandanus covered the hollows and banks of two small creeks with rocky water-holes going to the westward. About six miles from our last camp, an immense plain opened before us, at the west side of which we recognized the green line of the river. We crossed the plain to find water, but the approaches of the river were formed by tea-tree hollows, and by thick vine brush, at the outside of which noble bouquets of Bamboo and stately Corypha palms attracted our attention. In skirting the brush, we came to a salt-water creek (the first seen by us on the north-west coast), when we immediately returned to the ridges, where we met with a well-beaten foot-path of the natives, which led us along brush, teeming with wallabies, and through undulating scrubby forest ground to another large plain. Here the noise of clouds of water-fowl, probably rising at the approach of some natives, betrayed to us the presence of water. We encamped at the outskirts of the forest, at a great distance from the large but shallow pools, which had been formed by the late thunder-showers. The water had received a disagreeable sour aluminous taste from the soil, and from the dung of innumerable geese, ducks, native companions, white cranes, and various other water-fowl. The boggy nature of the ground prevented our horses and the bullock from approaching it; and they consequently strayed very far in search of water. In the forest land, the Torres Straits pigeon (Carpophaga luctuosa, GOULD,) was numerous. At sunset, Charley returned to the camp, accompanied by a whole tribe of natives. They were armed with small goose spears, and with flat wommalas; but, although they were extremely noisy, they did not show the slightest hostile intention. One of them had a shawl and neckerchief of English manufacture: and another carried an iron tomahawk, which he said he got from north-west by north. They knew Pichenelumbo (Van Diemen's Gulf), and pointed to the north-west by north, when we asked for it. I made them various presents: and they gave us some of their ornaments and bunches of goose feathers in return, but showed the greatest reluctance in parting with their throwing sticks (wommalas.) They were inclined to theft, and I had to mount Brown on horseback to keep them out of our camp.

Nov. 27.--The natives returned very early to our camp, and took the greatest notice of what we were eating, but would not taste anything we offered them. When Brown returned with our bullock, the beast rushed at them, and pursued them for a great distance, almost goring one of their number.

We travelled about three miles and a half north-east, but had to go fairly over ten miles of ground. We followed the foot-path of the natives for about two miles, passing over some scrubby ridges into a series of plains, which seemed to be boundless to the N.W. and N.N.W. A broad deep channel of fresh water covered with Nymphaeas and fringed with Pandanus, intercepted our course; and I soon found that it formed the outlet of one of those remarkable swamps which I have described on the preceding stages. We turned to the E. and E.S.E. following its outline, in order either to find a crossing place, or to head it. The natives were very numerous, and employing themselves either in fishing or burning the grass on the plains, or digging for roots. I saw here a noble fig-tree, under the shade of which seemed to have been the camping place of the natives for the last century. It was growing at the place where we first came to the broad outlet of the swamp. About two miles to the eastward, this swamp extended beyond the reach of sight, and seemed to form the whole country, of the remarkable and picturesque character of which it will be difficult to convey a correct idea to the reader. Its level bed was composed of a stiff bluish clay, without vegetation, mostly dry, and cracked by the heat of the sun; but its depressions were still moist, and treacherously boggy; in many parts of this extensive level, rose isolated patches, or larger island-like groves of Pandanus intermixed with drooping tea-trees, and interwoven with Ipomaeas, or long belts of drooping tea-trees, in the shade of which reaches of shallow water, surrounded by a rich sward of grasses of the most delicate verdure, had remained. Thousands of ducks and geese occupied these pools, and the latter fed as they waded through the grass. We travelled for a long time through groves of drooping tea-trees, which grew along the outline of the swamps, but using great caution in consequence of its boggy nature. Several times I wished to communicate with the natives who followed us, but, every time I turned my horse's head, they ran away; however, finding my difficulties increased, whilst attempting to cross the swamp, I dismounted and walked up to one of them, and taking his hand, gave him a sheet of paper, on which I wrote some words, giving him to understand, as well as I could, that he had nothing to fear as long as he carried the paper. By this means I induced him to walk with me, but considerably in advance of my train, and especially of the bullock; he kept manfully near me, and pointed out the sounder parts of the swamp, until we came to a large pool, on which were a great number of geese, when he gave me to understand that he wished Brown to go and shoot them; for these natives, as well as those who visited us last night, were well acquainted with the effects of fire arms.

We encamped at this pool, and the natives flocked round us from every direction. Boys of every age, lads, young men and old men too, came, every one armed with his bundle of goose spears, and his throwing stick. They observed, with curious eye, everything we did, and made long explanations to each other of the various objects presented to their gaze. Our eating, drinking, dress, skin, combing, boiling, our blankets, straps, horses, everything, in short, was new to them, and was earnestly discussed, particularly by one of the old men, who amused us with his drollery and good humour in trying to persuade each of us to give him something. They continually used the words "Perikot, Nokot, Mankiterre, Lumbo Lumbo, Nana Nana Nana," all of which we did not understand till after our arrival at Port Essington, where we learned that they meant "Very good, no good, Malays very far." Their intonation was extremely melodious, some other words, the meaning of which we could not make out, were "Kelengeli, Kongurr, Verritimba, Vanganbarr, Nangemong, Maralikilla;" the accent being always on the first syllable of the word, and all the vowels short.

Nov. 28.--Our good friends, the natives, were with us again very early in the morning; they approached us in long file, incessantly repeating the words above mentioned, Perikot, Nokot, etc. which they seemed to consider a kind of introduction. After having guided us over the remaining part of the swamp to the firm land, during which they gave us the most evident proofs of their skill in spearing geese--they took their leave of us and returned; when I again resumed my course to the northward. I understood from the natives that a large lake, or deep water, existed at the head of the swamp, far to the east and north-east. We travelled about nine miles north by east, to lat. 12 degrees 38 minutes 41 seconds.

A foot-path of the natives led us through an intricate tea-tree swamp, in which the rush of waters had uprooted the trees, and left them strewed in every direction, which rendered the passage exceedingly difficult. In the middle of the swamp we saw a fine camp of oven like huts, covered with tea-tree bark. After crossing some scrubby sandstone ridges, we came to a sandy creek, up which we proceeded until we found a small water-hole, which had been filled by the late thunder-storms, where we encamped.
