11TH SEPTEMBER.—Within 400 yards of the spot where we had slept, we found a small pond. The water was of that rich brown tint so well known to those with whom water is most precious, and to whom, after long custom, clear water seems, like some wines, to want body. Here we had breakfast, and we took also a bagful of water[*] with us. This timely supply relieved me from the necessity for following up the windings of some water-course; and I could proceed in a straight direction, westward. We passed, at first, through rather thick scrub, until, at length, I perceived a sharp pic before me, which I ascended. It consisted of trap rock, as did also the range to which it belonged, being rather a lateral feature thereof. Mount Hutton, Mount Pluto, and Mount Playfair, were all visible from it, as were also Mounts Owen and Faraday. The connections extended westward; for to the W.N.W. the broken cliffs at the head of the Salvator and the Claude, were not very distant, and these I was careful to avoid. A range immediately westward of this cone, was higher than it, and extended from Mount Playfair. To cross that range at its lowest part, which bore 26° W. of S., was our next object. We found the range covered with brigalow and other still more impervious scrubs. On the crest, the rock consisted of clay ironstone. The centigrade thermometer stood, at noon, at 30° 5' equal to 87°, of Fahrenheit; the height above the sea we made 2032 feet. Beyond this crest, we encountered a scrub of matted vines, which hung down like ropes, and pulled some of us off our horses, when it happened that any of these ropes were not observed in time in riding through the thicket. A very dense forest of young Callitris trees next impeded us, and were more formidable than even the vines. The day was passed in forcing our way through these various scrubs, the ground declining by a gentle slope only. We next found firmer soil underfoot, that where the Callitris scrub grew having been sandy, and we saw at length, with a feeling of relief, that only brigalow scrub was before us; we ascended gravelly hills, came upon a dry water-course, and then on a chain of ponds. Near one of these ponds, sate an old woman, beside a fire, of course, although the weather was very warm; and a large net, used for taking emus, hung on a brigalow bush close by. The men were absent, looking for food, as we partly conjectured, for little could Yuranigh make out of what she said, besides the names of some rivers, to which I could point with the hand. I was surprised to find that here, the name for water was "Narran," the name for it in the district of the Balonne being "Nadyeen," whereas the word for water amongst the tribes of the Darling is Kalli. That the "Narran" river and swamp are named from this language of tribes now dwelling much further northward, seems obvious; and, as the natives on the Darling know little of the "Narran" or its swamp, it may be inferred that there the migration of native tribes has been progressive from south to north; the highest known land in Australia being also to the southward of the Darling. The chain of ponds, according to the old woman, was named "Cùnno," and ran into the "Warreg" which, as she pointed, was evidently the name of the river we had formerly traced downwards from near Mount P. P. King. I left the "Cùnno," and plunged into the brigalow to the northward, thus crossing a slightly elevated range, where we found a little water-course falling N.N.W. By following this downwards, we found water in it, as twilight grew obscure, and gladly halted beside it for the night, in latitude 25° S.

12TH SEPTEMBER.—At 7 a.m. the thermometer was 59°; our height then above the sea has been ascertained to have been 1787 feet. Continuing to follow down the brigalow creek, we found that it joined a chain of ponds running N.E., and these we traced in the contrary direction, or upwards, as far as seemed desirable. We struck off from that water-course, first to the N.W., then to the W., arriving soon at a steep low ridge of clay ironstone, which was covered thick with brigalow. We crossed that low ridge, and, at a distance of about a mile and a half beyond, met another acclivity still more abrupt and stony. This we also ascended, and found upon it a "malga" scrub: the "malga" being a tree having hard spiky dry branches, which project like fixed bayonets, to receive the charge of ourselves, horses, and flour-bags; but all which formidable array we nevertheless successfully broke through, and arrived at the head of a rocky gully, falling N.W. Down this, however, we attempted in vain to pass, and in backing out we again faced the "malga," until, seeing a flat on the right, I entered it, and there fell in with the water-course again. It led us many miles, generally in a N.W. direction, and contained some fine ponds, and entered, at length, a little river, whose banks were thickly set with large yarra trees. The general course of this river was W.N.W., until it was joined by one coming from the N., and at the junction there was a deep broad pond of clear water. At this we watered our horses, and passed on to encamp under some rocky hills, three quarters of a mile to the N.N.W. of that junction, in latitude 24° 52' 50" S. The temperature at noon this day, on the highest part of the ridge we crossed, was 84°; the height there above the sea, 1954 feet; and at 3 p.m., in channel of water-course, the thermometer stood at 89°; the height there above the sea being 1778 feet.

13TH SEPTEMBER.—At 7 a.m. the thermometer stood at 38°; the height above the sea was found to be 1659 feet. I verily believed that THIS river would run to Carpentaria, and I called it the Nive, at least as a conventional name until the native name could be ascertained, in commemoration of Lord Wellington's action on the river of that name; and, to the tributary from the north, I gave the name of Nivelle. Pursuing the united channel downwards, we traversed fine open grassy plains. The air was fragrant from the many flowers then springing up, especially where the natives had burnt the grass. Among them were MORGANIA GLABRA; EREMOPHILA MITCHELLII; a singular little POLYGONUM with the aspect of a TILLOEA; two very distinct little FRANKENIAS[*], and a new scabrous HALORAGIS with pinnatifid leaves.[**] The extensive burning by the natives, a work of considerable labour, and performed in dry warm weather, left tracts in the open forest, which had become green as an emerald with the young crop of grass. These plains were thickly imprinted with the feet of kangaroos, and the work is undertaken by the natives to attract these animals to such places. How natural must be the aversion of the natives to the intrusion of another race of men with cattle: people who recognise no right in the aborigines to either the grass they have thus worked from infancy, nor to the kangaroos they have hunted with their fathers. No, nor yet to the emus they kill FOR their fathers ONLY; these birds being reserved, or held sacred, for the sole use of the old men and women!

The river pursued a course to the southward of west for nine miles, but it turned afterwards southward, eastward, and even to the northward of E. After tracing it thus twenty-two miles, without seeing any water in its bed (which was broad, but every where choked with sand), we were obliged to encamp, and endure this privation after a very warm and laborious day. Where the natives obtained water themselves, quite puzzled Yuranigh, for we passed by spacious encampments of theirs, and tracts they had set fire to, where trees still lay smoking.

14TH SEPTEMBER.—The temperature at 7 this morning was 72° of Fahrenheit; the height above the sea, of the river bed, as subsequently determined by Captain King, 1470 feet. With the earliest light, I had laid down my survey of this river, by which the course appeared to have turned towards the S.E. This not being what was desired, I took a direct northerly course through the scrub, towards a hill on the left bank, whence I had seen, on our way down, a rocky gap to the N.W. in a brigalow range. After a ride of eight miles, by which we cut off the grand curve in the river's course, we arrived at this hill. I hoped to have found water near the spot, in a sharp turn in the river which I had not examined, and near which, on the day before, I had seen two emus, under a bank covered with brigalow scrub. Nor was I disappointed, for after finding traces of a recent current into the river-bed at that point, I discovered, at less than a hundred yards up, a fine pond of precious OPAL—I mean not crystal, but that fine bluey liquid which I found always so cool and refreshing when it lay on clay in the shady recesses of brigalow scrubs, a beverage much more grateful to our taste than the common "crystal spring." Here, then, we watered our impatient horses, and enjoyed a wash and breakfast—the men (two old soldiers) being D'ACCORD in one sentiment of gratitude to a bountiful Providence for this water. Like "a giant refreshed with wine," we next set out for the gap to the north-west, and passed through an open brigalow scrub, ascending very gradually, during a ride of three miles, to where I at length could discover that the fall was in the other direction. At this point, I observed the barometer, which indicated our height above the sea to be 1812 feet. Fahrenheit's thermometer stood then (5 p.m.) at 86°. The dry channel of a water-course had afforded us an opening through the scrub, and had also guided us to the highest part of the ground. The fresh prints of the feet of three men in the smooth bare sand, told us that the same natives whose track Yuranigh had seen in the river we traced yesterday, were now going in the same direction as ourselves, and just before us; for the smell of their burning fire-sticks, and even small portions of burning embers which had dropped, made this evident. The higher ground was flat, and on it the rosewood acacia grew amongst the brigalow. The rocky gap (in a ridge) was still distant at least three miles; the sun nearly set, and not a blade of grass visible amongst the brigalow bushes. But what was all this to the romantic uncertainty as to what lay beyond! With eager steps we followed a slight channel downwards; found that it descended more rapidly than the one by which we had ascended; that it also increased, and we were guided by it into a little valley, verdant with young grass, while yet the red sky over a departed sun shone reflected from several broad ponds of water. This seemed to us a charming spot, so opportunely and unexpectedly found, and we alighted on a fine grassy flat by the margin of a small lagoon, where stood a most graceful group of bushes for shelter or shade. After sunset, the sky was overcast with very heavy clouds; the air was sultry, and we expected rain.

15TH SEPTEMBER.—As soon as daylight appeared I hastened towards the gap, and ascended a naked rock on the west side of it. I there beheld downs and plains extending westward beyond the reach of vision, bounded on the S. W. by woods and low ranges, and on the N. E. by higher ranges; the whole of these open downs declining to the N. W., in which direction a line of trees marked the course of a river traceable to the remotest verge of the horizon. There I found then, at last, the realization of my long cherished hopes, an interior river falling to the N. W. in the heart of an open country extending also in that direction. Ulloa's delight at the first view of the Pacific could not have surpassed mine on this occasion, nor could the fervour with which he was impressed at the moment have exceeded my sense of gratitude, for being allowed to make such a discovery. From that rock, the scene was so extensive as to leave no room for doubt as to the course of the river, which, thus and there revealed to me alone, seemed like a reward direct from Heaven for perseverance, and as a compensation for the many sacrifices I had made, in order to solve the question as to the interior rivers of Tropical Australia. To an European, the prospect of an open country has a double charm in regions for the most part covered with primaeval forests, calling up pleasing reminiscences of the past, brighter prospects for the future—inspiring a sense of freedom, especially when viewed from the back of a good horse:—

"A steed! a steed! of matchless speede, A sword of metal keene— All else to noble minds is drosse, All else on earth is meane!" —OLD SONG.
