We will now cast our eyes over the chart: and see if the position of the two rivers upon it, will at all bear out our conclusion that they are one and the same; and whether the line that would join them is the one that the Darling would naturally take, in reference to its previous course.—
We shall find that the two points under discussion, bear almost N.E. and S.W. of each other respectively, the direct line in which the Darling had been ascertained to flow, as far as it had been found practicable to trace it. I have already remarked that the fracture of my barometer prevented my ascertaining the height of the bed of the Darling above the sea, during the first expedition. A similar accident caused me equal disappointment on the second; because one of the most important points upon which I was engaged was to ascertain the dip of the interior. I believe I stated, in its proper place, that I did not think the Darling could possibly be 200 feet above the sea, and as far as my observations bear me out, I should estimate the bed of the Murray, at its junction with the new river, to be within 100. It would appear that there is a distance of 300 miles between the Murray River at this place, and the Darling; a space amply sufficient for the intervention of a hilly country. No one could have been more attentive to the features of the interior than I was; nor could any one have dwelt upon their peculiarities with more earnest attention. It were hazardous to build up any new theory, however ingenious it may appear. The conclusions into which I have been led, are founded on actual observation of the country through which I passed, and extend not beyond my actual range of vision; unless my assuming that the decline of the interior to the south has been satisfactorily established, be considered premature. If not, the features of the country certainly justify my deductions; and it will be found that they
were still more confirmed by subsequent observation.—That the Darling should have lost its current in its upper branches, is not surprising, when the level nature of the country into which it falls is taken into consideration; neither does it surprise me that it should be stationary in one place, and flowing in another; since, if, as in the present instance, there is a great extent of country between the two points, which may perhaps be of considerable elevation, the river may receive tributaries, whose waters will of course follow the general decline of the country. I take it to be so in the case before us; and am of opinion, that the lower branches of the Darling are not at all dependent on its sources for a current, or for a supply of water. I have somewhere observed that it appeared to me the depressed interior over which I had already travelled, was of comparatively recent formation. And, by whatever convulsion or change so extensive a tract became exposed, I cannot but infer, that the Darling is the main channel by which the last waters of the ocean were drained off. The bottom of the estuary, for it cannot be called a valley, being then left exposed, it consequently remains the natural and proper reservoir for the streams from the eastward, or those falling easterly from the westward, if any such remain to be discovered.
From the junction of the Morumbidgee to the junction of the new river, the Murray had held a W.N.W. course. From the last junction it changed its direction to the S.W., and increased considerably in size. The country to the south was certainly lower than that to the north; for, al
though both banks had features common to each other, the flooded spaces were much more extensive to our left than to our right.
We started on the morning of the 24th, all the lighter from having got rid of the skiff, and certainly freer to act in case the natives should evince a hostile disposition towards us. As we proceeded down the river, the appearances around us more and more plainly indicated a change of country. Cypresses were observed in the distance, and the ground on which they stood was higher than that near the stream; as if it had again acquired its secondary banks. At length these heights approached the river so nearly as to form a part of its banks, and to separate one alluvial flat from another. Their summits were perfectly level; their soil was a red sandy loam; and their productions, for the most part, salsolae and misembrianthemum. From this it would appear that we had passed through a second region, that must at some time have been under water, and that still retained all the marks of a country partially subject to flood.
We had, as I have said, passed over this region, and were again hemmed in by those sandy and sterile tracts upon which the beasts of the field could obtain neither food nor water. We overtook the seven deputies some time after we started, but soon lost sight of them again, as they cut off the sweeps of the river, and shortened their journey as much as possible. At 2 p.m. we found them with a tribe of their countrymen, about eighty in number. We pulled in to the bank and remained with them for a short
time, and I now determined to convince the blacks who had preceded us, that I had not been actuated by any other desire than that of showing to them that we were not to be intimidated by numbers, when I refused to make them any presents after their show of hostility. I now, therefore, gave them several implements, sundry pieces of iron hoop, and an ornamental badge of copper. When we left the tribe, we were regularly handed over to their care. The seven men who had introduced us, went back at the same time that we continued our journey, and two more belonging to the new tribe, went on a-head to prepare the the neighbouring tribe to receive us; nor did we see anything more of them during the day.
We encamped on the left bank of the river, amidst a polygonum scrub, in which we found a number of the crested pigeon. It was late before the tents were pitched: as Fraser seldom assisted in that operation, but strolled out with his gun after he had kindled a fire, so on this occasion he wandered from the camp in search of novelty, and on his return, informed me that there was a considerable ridge to the south of a plain upon which he had been.
I had myself walked out to the S.E., and on ascending a few feet above the level of the camp, got into a scrub. I was walking quietly through it, when I heard a rustling noise, and looking in the direction whence it proceeded, I observed a small kangaroo approaching me. Having a stick in my hand, and being aware that I was in one of their paths, I stood still until the animal came close up to me,
