We travelled during the day in a westerly direction over a level country, partly covered with reeds and fat-hen, and came to a broad sandy creek, which turned to the south-east and south. Having crossed it, we passed several large lagoons and swamps covered with plovers and ducks; and, at a short mile farther, came again on the creek, which now had a deep channel and a broad sandy bed lined with casuarinas and flooded-gum trees. I called this "Robinson's Creek." At its left bank, we saw a wide sheet of water, beyond which rose a range densely covered with scrub: I called them "Murphy's Lake and Range," after John Murphy, one of my companions. I believe that Robinson's Creek is a westerly water; and, if so, it is very remarkable that the heads of Palm-tree Creek, which flows to the eastward, should be scarcely a mile distant; and that the interesting space, separating the two systems of waters, should be, to all appearance, a dead level. I had descended--from a scrubby table land, the continuation of Darling Downs--into a system of easterly waters. I had followed down the Dawson for a considerable distance, and then, following up one of its creeks, found myself again on westerly waters. I could not decide, to my entire satisfaction, whether my views were right; for the country was difficult for reconnoitring; and I was necessarily compelled to move quickly on, to accomplish the object of my expedition: but it is a very interesting point for geographical research, and I hope, if I am not anticipated by other explorers, to ascertain, at some future period, the course of these creeks and rivers. Nov. 20.--The first part of the night till the setting of the moon was very clear; after this it became cloudy, but cleared again at sunrise, with the exception of some mackerel-sky and stratus to the north-west. During the forenoon it was again cloudy, and a thunder-storm occurred at half-past two o'clock from the north-west and west-north-west, with little rain, but a heavy gust of wind. In travelling to the westward, along Robinson's Creek, although two or three miles distant from it, we passed two lakes, one of which was a fine, long, but rather narrow, sheet of water, with swamps to the south-east. About six miles farther on, the country began to rise into irregular scrubby ridges; the scrub generally composed of Vitex intermingled with various forest trees. The small orange-tree, which we had found in blossom at the Condamine, was setting its fruit. Farther on, the dense Bricklow scrub compelled me to approach the banks of the creek, where we travelled over fine flats, but with a rather sandy rotten soil. The apple-tree, flooded-gum, silver-leaved ironbark, and the bastard-box grew on the flats and on the ridges. The creek was well provided with large water-holes, surrounded by high reeds.
