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.

ENCAMP AMIDST REEDS.

I was fearful that the reeds would have checked us; but there was a passage between the patches, through which we managed to force our way into a deep bight, and fortunately gained the river at the bottom of it much sooner than we expected. We were obliged to clear away a space for the tents; and thus, although there had been no such appearance from Mount Foster, we found ourselves in less than seven hours after leaving it, encamped pretty far in that marsh for which we had so anxiously looked from its summit, and now trusting to circumstances for safety, upon ground on which, in any ordinary state of the river, it would have been dangerous to have ventured. Indeed, as it was, our situation was sufficiently critical, and would not admit of hesitation on my part.

NATURE OF THE COUNTRY.

After the cattle had been turned out, Mr. Hume and I again mounted our horses, and proceeded to the westward, with a view to examine the nature of the country before us, and to ascertain if it was still practicable to move along the river side. For, although it was evident that we had arrived at what might strictly be called the marshes of the Macquarie, I still thought we might be at some distance from the place where Mr. Oxley terminated his journey.

There was no indication in the river to encourage an idea that it would speedily terminate; nor, although we were on ground subject to extensive inundation, could we be said to have reached the heart of the marshes, as the reeds still continued in detached bodies only. We forced a path through various portions of them, and passed over ground wholly subject to flood, to a distance of about six miles. We then crossed a small rise of ground, sufficiently high to have afforded a retreat, had necessity obliged us to seek for one; and we shortly afterwards descended on the river, unaltered in its appearance, and rather increased than diminished in size. A vast plain extended to the N.W., the extremity of which we could not discern; though a thick forest formed its northern boundary.

It was evident that this plain had been frequently under water, but it was difficult to judge from the marks on the trees to what height the floods had risen. The soil was an alluvial deposit, superficially sandy; and many shells were scattered over its surface. To the south, the country appeared close and low; nor do I think we could have approached the river from that side, by reason of the huge belts of reeds that appeared to extend as far as the the eye could reach.

MEN ATTACKED WITH OPHTHALMIA.

The approach of night obliged us to return to the camp. On our arrival, we found that the state of Henwood and Williams would prevent our stirring for a day or two. Not only had they a return of inflammation, but several other of the men complained of a painful irritation of the eyes, which were dreadfully blood-shot and weak. I was in some measure prepared for a relapse in Henwood, as the exposure which he necessarily underwent on the plain was sufficient to produce that effect; but I now became apprehensive that the affection would run through the party.
