30TH OCTOBER.—We were now fifty-two miles from the junction of the dry channel we crossed by the Balonne, and forty from the nearest part of our former route, in advancing into this country. The risk of want of water was worth encountering in the most direct line homewards, which was by following down this river. I travelled, as straight as the bush would allow, towards the junction; Graham examining the channel while we proceeded. No water was found where the rivers united. Having halted the small party with me, I followed one branch many miles with Yuranigh, but all we could find were some wells, dug by natives, in a part of the sandy bed; in one of which Yuranigh found, by a long bough he thrust in, that there was moisture about five feet below the surface. I returned, determined to encamp near this, and dig a well. The bullock teams had also arrived when I returned to the party, and I learnt that Drysdale, having observed that my little dog Procyon came in wet, had been led to the discovery of a lagoon about three miles back, at which the cattle had been already watered. I immediately encamped. At finding water the dog was most expert, the native next, we inferior to both. We had come about fifteen miles, and I wished to lay down the journey on the map. On doing this, I found we had at length attained a point from whence, in case of necessity, we could go as far as the Balonne, even if no water were found in the country intervening, the direct distance being under forty miles. During the afternoon, a still larger lagoon was found, higher up than the first. I resolved to give the cattle a day's rest, and then to proceed prepared, by well watering them previously, to travel on to the Balonne, but not with much expectation that scarcity of water would oblige us to go so far. Thermometer, at sunrise, 34°; at noon, 70°; at 4 P. M., 78°; at 9, 60°;—with wet bulb, 46°.

31ST OCTOBER.—Two men were sent to the westward, where they found a dry sandy country with pines, the same as that seen by me on my first ride from St. George's bridge to the N.W., on the 18th of April. I was myself engaged at the camp, on my general map of the country. Thermometer, at sunrise, 33°; at noon, 81°; at 4 p.m., 84°; at 9, 51° —wet bulb, 43°. Height above the sea, 882 feet.

1ST NOVEMBER.—The cattle and horses, having been all night loose beside Drysdale's ponds, were brought in early, and we then proceeded. After travelling about eight miles, over ground bearing traces of inundation, and looking, as we proceeded, into the river channel for water, Yuranigh found a lagoon in a hollow parallel to the river, and I encamped, resolved to reduce as much as possible the distance to be traversed in uncertainty about finding water. We had, however, found rocky ridges on the left, like bergs to the river; and the voices of natives in the woods, as well as these ridges, redeemed the country from the aspect of drought. This was but a small portion of the fine pastoral country, traversed by this river, where we found the channel dry; and I think this want was compensated by many lagoons and watercourses in that back country extending to the little river from Mount Abundance, the Cogoon.

2D NOVEMBER.—After watering all the animals, we went forward, prepared to go on to the Balonne, even if we should meet with no water until we arrived at that river. We found, however, that the country we were to traverse was well watered. Three miles on from our camp, the country appeared quite verdant, and park-like in its woods. The channel of the river was bordered with green reeds, and contained a deep reach of sparkling water. The river took a turn to the eastward, and, in the angle formed by its again turning south, a little tributary entered it from the north, which was full of ponds of water, and had not long ceased to run. This came from the rocky tract situated between our old line of route, along the little river Cogoon near Mount First View, and the Maranòa. The water now found supplied the only link wanting in our explored line along the last mentioned river, and I had no doubt that, by crossing that country more directly towards the upper part of the Maranòa, a supply would be found at convenient stages. On crossing the little tributary (which I called Requisite Ponds), we found that the river resumed its straight course towards the Balonne; and, in latitude 27° 31' 37" S., we again saw green reeds and a good pond, beside which we encamped. Thermometer, at sunrise, 50°; at noon, 76°; at 4 p.m., 79°; at 9, 63°; —with wet bulb, 61°. (Camp 82.) Height above the sea, 969 feet.

3D NOVEMBER.—The river accompanied us but a short way this day, as I had determined to follow a straight line towards the junction with the Balonne, aware that the course of the river, for ten or twelve miles above that point, turned very much to the westward. We passed through much open forest, and over much sandy ground, on which the callitris always appeared to predominate. Little scrub lay in our way. At length, plains again appeared before us through the trees; and, beyond them, after travelling twenty-two miles, we saw before us the river line, running north-east. We crossed it, and still continued to travel on towards the main river; but night overtook us when not far distant from it, so that we were obliged to encamp within the distance of a mile and a half, after a journey, with carts, of 26½ miles. Here occurred the only Epiphyte observed during the expedition. It was growing in the dead parts of trees in the forest, and proved to be the CYMBIDIUM CANALICULATUM of Brown. One of the specimens had a raceme of flowers above a foot long. The fragrant JASMINUM MITCHELLII occurred, with narrower leaves than usual, at the foot of the forest trees. JUSTICIA ADSCENDENS, an inconspicuous weed, covered the plains in large tufts. The MELALEUCA TRICHOSTACHYA was there; and on the plains, and in open forests, grew a woolly. ANDROPOGON, which appeared not to be distinct from the A. BOMBYCINUS. In the open forest grew, here and there, the delicate COESIA OCCIDENTALIS, and on the plains a small species of HEDYOTIS; a new CALOCEPHALUS in bunches[*], and a creeping plant, with yellow flowers, since found to be a new species of GOODENIA.[**] Thermometer, at sunrise, 51°; at noon, 85°; at 4 p.m., 86°; at 9, 66°;—with wet bulb, 54°. Height above the sea, 819 feet.

4TH NOVEMBER.—At an early hour we proceeded, and had the satisfaction soon to find our old wheeltracks along the bank of the majestic Balonne. This truly noble river was here as broad as the Thames at Richmond; its banks were verdant with a luxuriant crop of grass, and the merry notes of numerous birds gave the whole scene a most cheering appearance; especially to us who were again upon a route connected with home, and at a point 200 miles nearer to it, than where we had last seen that route. We had since made the discovery, and completed the survey, of the lower Maranòa, a river which had brought us in a very straight direction back to this point; and by tracing this down, we had established a well watered line of route back to the fine regions we had discovered in the more remote interior. I marked a tree at this camp (83.), which mark is intended to show where this route turns towards the Maranòa x. being marked at the next camp back along the old track. In the Balonne, huge cod-fish (GRISTES PEELII) were caught this afternoon; indeed, we already felt comparatively at home, although still far from the settled districts, and strangers to all that had been passing in the world during seven months. I was busy endeavouring to complete my maps before other cares should divert my attention from the one subject that had occupied it so long. But in perusing nature's own book, I could, at leisure, think sometimes on many other subjects, and I fancied myself wiser than when I set out,—much improved in health,—bronzed and bearded; sunproof, fly-proof, and water-proof: that is to say, proof against the want of it, "LUCUS A NON LUCENDO." Thermometer, at sunrise, 44°; at noon, 76°; at 4 p.m., 85°; at 9, 71°;—wet bulb, 59°. Height above the sea, 738 feet.

5TH NOVEMBER.—We now travelled back along our old track towards Camp VIII., at St. George's Bridge, where the first depôt had been stationed; the tracks of several horsemen, returning after rain, were visible along our route, and the prints of natives' feet with them. How far these parties had been further on, along the other route by which we had advanced, we could not then ascertain. In the course of our ride this day, we came suddenly upon two females, who were so busy digging roots on a plain crossed by our track, that we were too near to admit of their running off before they perceived us; they therefore remained on the spot until we went up to them. They informed us, through Yuranigh, that "the tracks were those of five white men on horseback, who had been accompanied by natives on foot. They came there about one moon before then, and had been looking very much all about; these females could not think what for." We took up our old position, overlooking the rocky bed of the river. Pieces of old iron had been left untouched by the natives, both at this camp, and were found on our old track in returning. As these articles were such as they could have made great use of, I considered their leaving them a proof of their good disposition towards the exploring party; and of the very favourable impression we had made formerly on the aborigines, at the interview with the assembled tribes of this river. In the scrubs adjacent, we found, for the first time, the ripe fruit of the "Quandang" (FUSANUS ACUMINATUS), and several shrubs in flower that we thought new to botany. Thermometer, at sunrise, 44°; at noon, 76°; at 4 p.m., 85°; at 9, 71°;—wet bulb, 59°.
