To a certain distance from the banks, there was less fallen timber, as the natives had been accustomed there to make their fires, and roast the mussles of the river, and other food. The river was found to spread into separate channels, in which I did not readily recognise it, until I found them again united in a splendid reach of water under steep banks. The general course was by no means promising, being somewhat to the E. of N.; it was much to be apprehended that this river, too, would run to the E. coast, and become another instance of the utter want of any knowledge of the interior country, that still may prevail, long after complete surveys have been made of the lines of coast. Again we came upon wide fields of polygonum, and tracks of open forest with large lagoons. Then scrubs of brigalow obliged us to travel in the river bed, as the only open part where we could pass. That surface consisted of clay iron-stone, denuded by torrents, and the "DISJECTA MEMBRA," of a river. Ponds, water-worn banks, and timber, alive and dead, were there intermixed. Emerging from these obstructions, as from a feverish dream, we entered upon park-like scenery and good grass. The latter had been a desideratum during the last two days. We next came upon a river containing plenty of water, and coming from the N.W. I expected this would terminate our journey along the other, and I encamped on discovering it, after a journey of ten miles. The Australian rivers have all distinguishing characteristics, which they seem to possess from their sources to their termination. That we had just quitted, had a great affection, like its upper tributary, for brigalow scrubs, and spreading into ana-branches. This last discovered river seemed quite the reverse of all this. Its channel was very uniform; the banks being covered with open forests and good grass.
