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 deg.; at noon, 100 deg.; at 4 P.M., 101 deg.; at 9, 81 deg.; with wet bulb, 61 deg.. 2ND MARCH--MONDAY. I took a ride to examine the ford at Wyabry, (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 Barwan 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 deg.; at noon, 101 deg.; at 4 P.M.; 100 deg.; at 9, 78 deg.; and with wet bulb, 62 deg.. [* See "Three Expeditions," etc., vol. i. page 315.]
