Two Expeditions into the Interior of Southern Australia — Volume 2

by Charles Sturt

We encamped rather earlier than usual upon the left bank of the river, near a broad creek; for as the skiff had been a great drag upon us, I determined on breaking it up, since there was no probability that we should ever require the still, which alone remained in her. We, consequently, burnt the former, to secure her nails and iron work, and I set Clayton about cutting the copper of the latter into the shape of crescents, in order to present them to the natives. Some large huts were observed on the side of the creek, a little above the camp, the whole of which faced the N.E. This arrangement had previously been noticed by us, so that I was led to infer that the severest weather comes from the opposite quarter in this part of the interior. I had not the least idea, at the time, however, that we should, ere we reached the termination of our journey, experience the effects of the S.W. winds.

We must have fallen considerably during the day from the level of our morning's position, for we passed down many reaches where the decline of country gave an increased velocity to the current of the river.

I had feared, not only in consequence of the unceremonious manner in which we had left them, but, because I had, in some measure, rejected the advances of their chiefs, that none of the natives would follow us, and I regretted the circumstance on account of my men, as well as the trouble we should necessarily have in conciliating the next tribe. We had not, however, been long encamped, when seven blacks joined us. I think they would have passed on if we had not called to them. As it was, they remained with us but for a short time. We treated them very kindly, but they were evidently under constraint, and were, no doubt, glad when they found we did not object to their departing.

NEW RIVER IDENTIFIED WITH THE DARLING.

I have stated, that I felt satisfied in my own mind, that the beautiful stream we had passed was no other than the river Darling of my former journey. The bare assertion, however, is not sufficient to satisfy the mind of the reader, upon a point of such importance, more especially when it is considered how remarkable a change the Darling must have undergone, if this were indeed a continuation of it. I am free to confess that it required an effort to convince myself, but after due consideration, I see no reason to alter the opinion I formed at a moment of peculiar embarrassment. Yet it by no means follows that I shall convince others, although I am myself convinced. The question is one of curious speculation, and the consideration of it will lead us to an interesting conjecture, as to the probable nature of the distant interior, between the two points. It will be remembered that I was obliged to relinquish my pursuit of the Darling, in east long. 144 degrees 48 minutes 30 seconds in lat. 30 degrees 17 minutes 30 seconds south. I place the junction of the Murray and the new river, in long. 140 degrees 56 minutes east, and in south lat. 34 degrees 3 minutes. I must remark, however, that the lunars I took on this last occasion, were not satisfactory, and that there is, probably, an error, though not a material one, in the calculation. Before I measure the distance between the above points, or make any remarks on the results of my own observations, I would impress the following facts upon the reader's mind.

I found and left the Darling in a complete state of exhaustion. As a river it had ceased to flow; the only supply it received was from brine springs, which, without imparting a current, rendered its waters saline and useless, and lastly, the fish in it were different from those inhabiting the other known rivers of the interior. It is true, I did not procure a perfect specimen of one, but we satisfactorily ascertained that they were different, inasmuch as they had large and strong scales, whereas the fish in the western waters have smooth skins. On the other hand, the waters of the new river were sweet, although turbid; it had a rapid current in it; and its fish were of the ordinary kind. In the above particulars, therefore, they differed much as they could well differ. Yet there were some strong points of resemblance in the appearance of the rivers themselves, which were more evident to me than I can hope to make them to the reader. Both were shaded by trees of the same magnificent dimensions; and the same kind of huts were erected on the banks of each, inhabited by the same description, or race, of people, whose weapons, whose implements, and whose nets corresponded in most respects.

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, although both banks had features common to each other, the flooded spaces were much more extensive to our left than to our right.

CHANGE OF COUNTRY.

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.
