We proceeded on the same bearing, travelling over a very level surface. As we approached the western extremity of the great range, we touched on an open plain, whereof the soil was very rich. The greater portion of it lay on the left, or westward of our route, or towards the river. After crossing it we again entered a thin scrub of Acacia pendula, which having been recently burnt was open and favourable for passing through. We afterwards crossed a succession of gentle undulations, and through an opening, along the bottom of one valley, I obtained a view over the flat country to the westward. The most remarkable feature was a naked ridge of yellowish rock which rose abruptly from the woody country, as if it overhung the river. I wished much to examine that singular mass, but we were proceeding with little prospect of finding water, and we had impassable scrubs before us, as well as rocky hills on our right. A valley at length appeared in our route, and in which from the nature of the mountains at its head, I hoped to find water. In this I was however disappointed, for the channel, although of considerable depth, was quite dry, and I in vain searched its bed for at least a mile upwards. At ten miles the most western head of the range of Nundewar bore north, its low western extremity being distant only about a quarter of a mile. We were about to cross some offsets from the range, when a thick scrub or brush obstructed our further progress in that direction. I entered it and penetrated about a mile and a half without discovering any indication of water, or any opening through which the carts might pass. The weather was extremely warm, and as we had come a long journey, I determined to encamp once more on the Namoi; and turning westward I followed a line of flats and hollows, which led me to the nearest bend of that river. We calculated we had travelled twenty-one miles, although the distance by latitude and angles taken on the hills is less. Thermometer 97 degrees in the shade. Where we encamped the river was shallow, with many dead trees in the channel; but a little lower down it formed a deep, broad, and extensive reach. The latitude as ascertained by the stars Aldebaran and Rigel was 30 degrees 24 minutes 44 seconds South. January 2.
