The impossibility of proceeding further in conjunction with the boats being evident, I determined upon maturer deliberation, to haul them up, and divesting ourselves of everything, that could possibly be spared, proceed with the horses loaded with the additional provisions from the boats, in such a course towards the coast as would intersect any stream that might arise from the divided waters of the Lachlan. In pursuance of this plan, I quitted the river on the 11th May, taking a south-west course towards Cape Northumberland, as the best one to answer my intended purpose. I will not here detail the difficulties and privations we experienced in passing through a barren and desolate country, without any water but such rain water as was found remaining in holes and the crevices of rocks. I continued this course until the 9th of June, when having lost two horses through fatigue and want, and the others in a deplorable condition, I changed our course to north, along a range of lofty hills, running in that direction, as they afforded the only means of procuring water until we should fall in with some running stream. On this course I continued until the 23d of June, when we again fell in with a stream, which we had at first some difficulty to recognise as the Lachlan, it being little larger than one of the marshes of it, where it was quitted on the 17th of May. I did not hesitate a moment to pursue this course; not that the nature of the country, or its own appearance in any manner indicated that it would become navigable, or was even permanent; but I was unwilling that the smallest doubt should remain of any navigable waters falling westward into the sca, between the limits pointed out in my instructions. I continued along the banks of the stream until the 8th of July, it having taken during this period a westerly direction, and passing through a perfectly level country, barren in the extreme, and being evidently at periods entirely under water. To this point it had been gradually diminishing, and spreading its waters over stagnated lagoons and morasses, without receiving any stream that we knew of during the whole extent of its course. The banks were not more than three feet high, and the marks of flood in the shrubs and bushes, shewed that at times it rose between two and three feet higher, causing the whole country to become a marsh, and altogether uninhabitable. Further progress westward, had it been possible, was now useless, as there was neither hill nor rising ground of any kind within the compass of our view, which was only bounded by the horizon in every quarter, entirely devoid of timber except a few diminutive gums on the very edge of the stream, might be so termed. The water in the bed of the lagoon, as it might now be properly denominated, was stagnant; its breadth about twenty feet, and the heads of grass growing in it, shewed it to be about three feet deep.
