essential to trace the river, as I could not move upon its banks, and wishing also to ascertain where it again issued from the marshes, I requested Mr. Hume to proceed northerly, with a view to skirt them, and to descend westerly, wherever he saw an open space. He was fortunate enough to strike upon the channel about twelve miles north of our position, but was obstructed in his further progress by another marsh, in consequence of which he returned to the camp the next day; in the mean time, I had taken the boat, and proceeded down the Macquarie, my way being at first considerably obstructed by fallen timber: clearing this obstacle, however, I got into a deeper channel, with fine broad reaches, and a depth of from twelve to fifteen feet water. I had a short time previously cleared all woods and trees, and was now in the midst of reeds of great height. After proceeding onwards for about eight miles from the place whence I started, my course was suddenly and unexpectedly checked; I saw reeds before me, and expected I was about to turn an angle of the river, but I found that I had got to the end of the channel, and that the river itself had ceased to exist. Confounded at such a termination to a stream, whose appearance justified the expectation that it would have led me through the heart of the marsh to join Mr. Hume, I commenced a most minute examination of the place, and discovered two creeks, if they deserve the name, branching, the one to the north-west, and the other to the north-east; after tracing the former a short distance, I reached its termination, and in order to assure myself that such was the case, I walked round the head of it by pushing through the reeds; it being then too dark to continue where I was, I returned to
a place on the river, at which I had rested during a shower, and slept there. In the morning I again went to the spot to examine the north-eastern branch, when I was equally disappointed. I then examined the space between the two creeks, opposite to the main channel of the river, and where the bank receives the force of the current. Here I saw water in the reeds, but it was scarcely ankle deep, and was running off to the north-west quicker than the waters of the river, which had almost an imperceptible motion, I was therefore at once convinced that it was not permanent, but had lodged there in the night, during which much rain had fallen. I next pushed my way through the reeds into the marsh, and at length clearly perceived that the waters which were perfectly sweet, after running several courses, flowed off to the north, towards which point there was an apparent declination or dip. Finding it impossible to proceed further, I regained the boat, and thence returned to the camp, under a conviction that I had reached the very spot, at which Mr. Oxley lost the channel of the river in 1818.
The next day I moved to the place where Mr. Hume had struck upon the channel of the river, but was again doubtful in what direction to proceed.
The marsh, at the commencement of which we now found ourselves, being the third from Mount Foster, but the second great one, seemed to extend beyond us to the north for many miles, but varying in breadth. In the evening I went in the boat up the channel, and found it at first, deep and sullen, as that of the river above. It soon however, narrowed, and the weeds formed over its surface, so that I abandoned the boat and walked along a path up it. I had not gone far when the channel divided; two
smaller channels came, the one from the southern, and the other from the western parts of the marsh into it. There was an evident declination where they were, and it was at their junction the river again rallied and formed. On my return to the camp, Mr. Hume and I went down the river, but found that about a mile it lost itself, and spread its waters ever the extensive marsh before it.
In this extremity, I knew not what movement to make, as Mr. Hume had been checked in his progress north. I therefore determined to ascertain the nature of the country to the eastward and to the westward, that I might move accordingly; I proposed to Mr. Hume, to take a week's provisions, with two attendants, and go to the north-east, in order again to turn the marsh, but with the expectation that the angle formed by the junction of the Castlereagh with the Macquarie would arrest its progress, as the last was fast approaching the former.
I myself determined to cross the river, and to skirt the marshes on the left, and in case they turned off to the north east, as they appeared to do, it was my intention to pursue a N.W. course into the interior, to learn the nature of it. With these views I left the camp on the 31st of December, and did not return until the 5th of January. Having found early in my journey, from the change of soil and of timber, that I was leaving the neighbourhood of the Macquarie, I followed a N.W. course, from a more northerly one, and struck at once across the country, under an impression that Mr. Hume would have made the river again long before my return. I found, after travelling between twenty and thirty miles, the country began to rise; and at the end of my journey, I made a hill of considerable
elevation, from the summit of which I had a view of other high lands; one to the S.W. being a very fine mountain. As I had not found any water excepting in two creeks, which I had left far behind me, and as I had got on a soil which appeared incapable of holding it, I made this the termination of my journey, having exceeded 100 miles in distance from the camp, on my return to which I found Mr. Hume still absent. When he joined, he stated to me, that not making the Castlereagh as soon as he expected, he had bent down westerly for the Macquarie, and that he ended his journey at some gentle hills he had made; so that it appeared we must either have crossed each other's line of route, or that they were very near, and that want of length must alone have prevented them from crossing; but as such all assumption led to the conclusion that the Macquarie no longer existed, I determined to pursue a middle course round the swamps, to ascertain the point; as in case the river had ended, a westerly course was the one which my instructions directed me to pursue.
In the immediate neighbourhood of the marshes we were obliged to sink wells for water, and it was thus early that we began to feel the want of a regular supply.
Having made a creek about four miles from our position by cutting through the reeds where there was a narrow space, we pursued a westerly course over a plain, having every appearance of frequent inundation, and for four or five days held nearly the same direction; in the course of which we crossed both our tracks on the excursions we had made, which had intersected each other in a dense oak brush; thus renewing the few doubts, or rather the doubt
