1ST MARCH.—When, fifteen years before, I visited this river at a higher point where it was called the Karaula [*], no trace of hoofs of horses or bullocks had been previously imprinted on the clayey banks. Now, we found it to be the last resource of numerous herds in a dry and very hot season, and so thickly studded were the banks of this river with cattle stations, that we felt comparatively at home. The ordinary precautionary arrangements of my camp against surprise by savage natives seemed quite unnecessary, and, to stockmen, almost ridiculous. We had at length arrived at the lowest drain of that vast basin of clay absorbing many rivers, so that they lose themselves as in the ocean. Here the final outlet or channel of the waters of the Macquarie, was but a muddy ditch one might step across, which the magnificent flood we had seen in the same river above the marshes was not at all likely to reach. That flood had gone to fill thousands of lagoons, without which supply, those vast regions had been unfit for animal existence. Here we discover another instance of that wonderful wisdom which becomes more and more apparent to man, when he either looks as far as he can into space, or attentively examines the arrangement of any matter more accessible to him. The very slight inclination of the surface of these extensive plains seems finely adapted to the extremely dry and warm climate over this part of the earth. If the interior slope of the land from the eastern coastranges were as great as that in other countries supplying rivers of sustained current, it is obvious that no water would remain in such inclined channels here; but the slope is so gentle that the waters spread into a net-work of reservoirs, that serve to irrigate vast plains, and fill lagoons with those floods that, when confined in any one continuous channel, would at once run off into the ocean.
[* We then understood the natives very imperfectly and might have been wrong about the name, which is the more likely, as caràwy, which the name resembles, means any deep water-hole.]
In a wet season, the country through which we had traced out a route with our wheels had been impassable. The direction I should have preferred, and in which I had endeavoured to proceed, was along the known limits of this basin, and formed a curved line, or an arc, to which the route necessity had obliged us to follow was the chord; thus we had not lost time; but had, in fact, shortened the distance to be travelled over very considerably. A permanent route had, however, seemed to me more desirable to any country we might discover, than one liable to be interrupted by flooded rivers and soft impassable ground. The track of our drays, along the western side of the Macquarie marshes opened a new and direct route from Sydney to the banks of the river Darling, by way of Bathurst; and afforded access to a vast extent of excellent pasturage on the Macquarie, along the western margin of the marshes, which land would, no doubt, be soon taken up by squatters. In so dry a climate, and where water is so frequently scarce, it may, indeed, be found that the shortest line of route with such advantages would be more frequented than any longer line, possessing only the remote advantage of security from interruption by too much water. Thermometer at sunrise, 64°; at noon, 100°; at 4 p.m., 101°; at 9, 81°; with wet bulb, 61°.
2ND MARCH—MONDAY. I took a ride to examine the ford at Wyàbry, (Mr. Parnell, Jun.'s station,) which I found practicable for our drays, although, for their descent and ascent, it was necessary to cut better approaches on each side. The Macquarie, although the channel was so attenuated and ditch-like, was likely to prove also an obstacle without some work of the same kind. Accordingly, on my return to the camp, I sent some men to the last-mentioned work.
I learnt from natives whom I met at Mr. Parnell's station, that the rivers Bolloon, Culgoa, and Biree were then flowing, some abundant rains having fallen about their sources. Also, from the stockman, that the Narran was thirty-five miles distant, but that a native could be found to guide me to water only ten miles off. Water was also to be obtained at a distance of only seven miles beyond the Bàrwan there at the "Morella Ridges," to which the natives were in the habit of resorting at certain seasons, by a path of their own, to gather a fruit of which they were very fond, named by them "Moguile," and which I had previously ascertained to be that formerly discovered by me, and named by Dr. Lindley Capparis Mitchellii.[*] We found back from this camp the Rutidosis helychrysoides of De Candolle. Thermometer at sunrise, 72°; at noon, 101°; at 4 p.m.; 100°; at 9, 78°; and with wet bulb, 62°.

3D MARCH.—Early this morning a party of men were sent to cut better approaches to the ford across the Bàrwan at Mr. Parnell's station. Ascertained the longitude of the junction of the rivers Macquarie and Darling at our present camp to be 147° 33' 45" E., by actual measurements connected with my former surveys of the colony. Mr. Kennedy had chained the whole of the route from Bellaringa, and I had connected his work with latitudes observed at almost every encampment, and after determining at various points the magnetic variation, which appeared to be very steady, I made the latitude of this camp 30° 6' 11" south. Thermometer at sunrise, 72°; at noon, 99°; at 4 p.m., 97°; at 9, 72°; and with wet bulb, 65°. The height above the sea level of the bed of the river here, the average result of eight observations, as calculated by Capt. King, was 415 feet.
4TH MARCH.—The party moved off towards the ford over the Bàrwan at Wyàbry, crossing the bed of the Macquarie about half a mile above its junction with the Bàrwan; there, although the approaches had been well enough cut, we found the bottom too soft for our heavy vehicles, one of which dipped its wheel to near the axle. We were obliged to pave the soft and muddy bed with logs, and to cover these with branches, on which earth was thrown, ere the rest could be got across. The party arrived about noon at Wyàbry, and by 2 p.m. the whole was safely encamped on the right bank of the Bàrwan. I had received this morning a dispatch from my son, commissioner of this district, in which he gave me a most favourable account of several rivers he had explored in the direction of my proposed route. These dispatches came to me at the last camp by the hands of a native, in forty-four hours after the superintendent of Mr. Lawson, being then on his way down the river, had promised to send them to me, from a station forty-five miles off, towards Fort Bourke, where it had been supposed my party would pass. Lat. of this camp, 30° 5' 41" S. On this northern bank of the Darling we looked for novelty in botany, and found some interesting plants, such as a toothed variety of Senerio brachyloenus D. C., a kind of groundsel; Morgania floribunda, loaded with purple blossoms, and a variety of Helichrysum bracteatum, somewhat different in the leaves from the usual state of the species. Thermometer at sunrise, 70°; at 4 p.m., 98°; at 9, 72°;—with wet bulb, 61°.
