9TH MARCH.--My native guides, tired of the delay, were anxious to return, and as the assistance they could afford me was likely to be extremely useful, and the arrival of the drays was most uncertain, I went forward this morning with one of them, two men, and Youranigh, our interpreter, all mounted. Amongst the trees, beyond the swamp, fine reaches of water appeared in a river channel, apparently continuous to the northward, but which, in the other direction, or towards the swamp, abruptly terminated like a cul-de-sac. On my asking the natives where it went to, they pointed to the various narrow water courses and the swamp as the final depositories of the water. Admirable distribution of the contents of a river in a country where water is so scarce, and the climate so hot and dry! We proceeded along the margin of the "Narran," which led us nearly due north, until we forded it, at the desire of our guides, on a good gravelly bottom, the water reaching to our saddle-flaps. Crossing a slight elevation where the soil was gravelly, and in which grew the shrubs of the ordinary scrubs with several interesting novelties, we again came upon an angle of the Narran, and continued along its banks for about thirty miles, until near sunset, when we tethered our horses, and lay down for the night. The Narran was full of water every where, and with this abundance of water there was also plenty of most excellent grass. The PANICUM LOEVINODE of Dr. Lindley seemed to predominate, a grass whereof the seed ("Cooly") is made by the natives into a kind of paste or bread. Dry heaps of this grass, that had been pulled expressly for the purpose of gathering the seed, lay along our path for many miles. I counted nine miles along the river, in which we rode through this grass only, reaching to our saddle-girths, and the same grass seemed to grow back from the river, at least as far as the eye could reach through a very open forest. I had never seen such rich natural pasturage in any other part of New South Wales. Still it was what supplied the bread of the natives; and these children of the soil were doing every thing in their power to assist me, whose wheel tracks would probably bring the white man's cattle into it. We had followed well-beaten paths of natives during the whole of this day's ride, and most anxious were my guides and I to see them; but they avoided us. Our guide was of that country, and not at all unwilling or timid; but evidently very desirous to introduce us to the inhabitants, and procure amongst them other guides to lead us further. The night was very hot, and flies and mosquitos did their utmost to prevent us from sleeping. Thermometer at sunrise, 75 deg.; at noon, 99 deg.; at 4 P. M., 105 deg.; at 9, 83 deg.; ditto with wet bulb, 75 deg..
