I stayed on the mount until after sunset, but I could not make out any space that at all resembled the formidable barrier I knew we were so rapidly approaching. I saw nothing to check our advance, and I therefore returned to the camp, to advise with Mr. Hume upon the subject. Not having been with me on Mount Foster, he took the opportunity to ascend it on the following morning; and on his return concurred with me in opinion, that there was no apparent obstacle to our moving onwards. As the men were considerably better, I had the less hesitation in closing with the marshes. We left our position, intending to travel slowly, and to halt early. The first part of our journey was over rich flats, timbered sufficiently to afford a shade, on which the grass was luxuriant; but we were obliged to seek more open ground, in consequence of the frequent stumbling of the cattle. We issued, at length, upon a plain, the view across which was as dreary as can be imagined; in many places without a tree, save a few old stumps left by the natives when they fired the timber, some of which were still smoking in different parts of it. Observing some lofty trees at the extremity of the plain, we moved towards them, under an impression that they indicated the river line. But on this exposed spot the sun's rays fell with intense power upon us, and the dust was so minute and penetrating, that I soon regretted having left the shady banks of the river. About 2.p.m. we neared the trees for which we had been making, over ground evidently formed by alluvial deposition, and were astonished to find that reeds alone were growing under the trees as far as the eye could penetrate. It appeared that we were still some distance from the river, and it was very doubtful how far we might be from water, for which the men were anxiously calling. I therefore halted, and sent Fraser into the reeds towards some dead trees, on which a number of spoonbills were sitting. He found that there was a small lake in the centre of the reeds, the resort of numerous wild fowl; but although the men were enabled to quench their thirst, we found it impossible to water the animals. We were obliged, therefore, to continue our course along the edge of the reeds; which in a short time appeared in large masses in front of us, stretching into a vast plain upon our right; and it became evident that the whole neighbourhood was subject to extensive inundation.
