Journal of an Overland Expedition in Australia. Ludwig Leichhardt

fatiguing to myself, I arranged that both the blacks should go with me, in order that I might send one back from the first favourable camping place, to bring the party on, whilst I continued to explore the country with the other. Under this arrangement, therefore, I went forward, and, following the creek, it was found to sweep to the eastward, round a high plain of rich black soil, and covered with luxuriant vegetation. This plain is basaltic, but, in the valley of the creek, sandstone crops out below it. The slopes from the plain to the creek are steep, and torn by deep gullies, which made travelling very fatiguing. As the creek again turned to the west and north-west, the water-holes increased both in size and number, although the flats within the valley were limited and intersected by watercourses. I sent Charley back when we were about seven miles N.W. by N. from our camp, and proceeded with Brown down the creek, which, at about four miles farther, to my inexpressible delight, joined a river coming from the west and north-west, and flowing to the east and north-east. It was not, however, running, but formed a chain of small lakes, from two to three and even eight miles in length, and frequently from fifty to one hundred yards broad, offering to our view the finest succession of large sheets of water we had seen since leaving the Brisbane. Its course continued through a very deep and winding valley, bounded by high but generally level land. The gullies going down to the river were generally covered with a belt of thick scrub, as was also the high land nearest to it; but, farther off, the country appeared to be more open, plains alternating with open forest land, but yet, in places, much occupied by tracts of almost impervious scrub of various extent. We met frequent traces of the natives, who had recently gone down the river, having previously burned the grass, leaving very little for our horses and cattle. At 8 o'clock P.M. a fine strong northerly breeze came up the river, flowing along its broad open valley, and which I supposed to be the sea breeze. This supposition was somewhat confirmed by a similar breeze occurring at the same time on the following evening.

      The plains are basaltic, and occasionally covered with pebbles of white and iron-coloured quartz and conglomerate, and are in the vicinity of slight elevations, which are probably composed of sandstone and conglomerate, and usually covered with low scrub and cypress-pine. Sandstone crops out in the gullies of the valley, in horizontal strata, some of which are hard and good for building, others like the blue clay beds of Newcastle, with the impressions of fern-leaves identical with those of that formation. At the junction of Comet Creek and the river, I found water-worn fragments of good coal, and large trunks of trees changed into ironstone. I called this river the "Mackenzie," in honour of Sir Evan Mackenzie, Bart., as a small acknowledgment of my gratitude for the very great assistance which he rendered me in the preparations for my expedition. Farther down the river, the country became better watered, even at a distance from the river; some small creeks, winding down between scrubby sandstone hills, were full of water, and a chain of fine lagoons was crossed, covered with splendid blue Nymphaeas. Large coveys of partridge-pigeons rose from the burnt grass as we passed along, and ducks and pelicans were numerous on the stretches of water in the bed of the river. Heaps of fresh-water muscles lined the water-holes, which were teeming with fish, apparently of considerable size, as their splashing startled me several times during the night, and made me believe, for the moment, that a large tribe of natives were bathing.
