channel, into a foaming and impetuous stream, rolling along its irresistible and turbid waters, to add to those of the Murray.
There can be no doubt, but, that this sudden rise in the river, was caused by heavy rains on the mountains, in which its tributaries are to be found, for the Darling does not receive any accession to its waters below their respective junctions, of sufficient magnitude to account for such an occurrence. [Note 1. below]
[Note 1. The principal tributaries of the Darling, are the Kindur, the Keraula, the Namoy, and the Gwydir. They are beautiful mountain streams, and rise in the hilly country, behind Moreton Bay, in lat. 27 degrees, and in longitude 152 degrees E.]
When, on the return of the expedition homewards the following year, some two months later in the season than that of which I have just been speaking, Oct. 1844, there had been no recurrence of the flood of the previous year, but the Darling was at a still lower ebb than before, and every lagoon, and creek in its vicinity had long been exhausted and waterless. [Note 2. below] Now, it is evident, as far as I can judge, that if the rains of Australia were as regular as in other countries, its rivers would also be more regular in their flow, and would not present the anomaly they now do, of being in a state of rapid motion at one time, and motionless at another.
[Note 2. It may be necessary to warn my readers that a creek in the Australian colonies, is not always an arm of the sea. The same term is used to designate a watercourse, whether large or small, in which the winter torrents may or may not have left a chain of ponds. Such a watercourse could hardly be called a river, since it only flows during heavy rains, after which it entirely depends on the character of the soil, through which it runs, whether any water remains in it or not.]
A lagoon is a shallow lake, it generally constitutes the back water of some river, and is speedily dried up. In Australia, there is no surface water, properly so called, of a permanent description.]
But, although I am making these general observations on the rivers, and to a certain extent of climate of Australia, I would not be understood to mean more than that its seasons are uncertain, and that its summers are of comparatively long duration.
In reference to its rivers also, the Murray is an exception to the other known rivers of this extensive continent. The basins of that fine stream are in the deepest recesses of the Australian Alps--which rise to an elevation of 7000 feet above the sea. The heads of its immediate tributaries, extend from the 36th to the 32nd parallel of latitude, and over two degrees of longitude, that is to say, from the 146 degrees to the 148 degrees meridian, but, independently of these, it receives the whole westerly drainage of the interior, from the Darling downwards. Supplied by the melting snows from the remote and cloud-capped chain in which its tributaries rise, the Murray supports a rapid current to the sea. Taking its windings into account, its length cannot be less than from 1300 to 1500 miles. Thus, then, this noble stream preserves its character throughout its whole line. Uninfluenced by the sudden floods to which the other rivers of which we have been speaking are subject, its rise and fall are equally gradual. Instead of stopping short in its course as they do, its never-failing fountains have given it strength to cleave a channel through the desert interior, and so it happened, that, instead of finding it terminate in a stagnant marsh, or gradually exhausting itself over extensive plains as the more northern streams do, I was successfully borne on its broad and transparent waters, during the progress of a former expedition, to the centre of the land in which I have since erected my dwelling.
Sunset on the Murray
As I have had occasion to remark, the rise and fall of the Murray are both gradual. It receives the first addition to its waters from the eastward, in the month of July, and rises at the rate of an inch a day until December, in which month it attains a height of about seventeen feet above its lowest or winter level. As it rises it fills in succession all its lateral creeks and lagoons, and it ultimately lays many of its flats under water.
The natives look to this periodical overflow of their river, with as much anxiety as did ever or now do the Egyptians, to the overflowing of the Nile. To both they are the bountiful dispensation of a beneficent Creator, for as the sacred stream rewards the husbandman with a double harvest, so does the Murray replenish the exhausted reservoirs of the poor children of the desert, with numberless fish, and resuscitates myriads of crayfish that had laid dormant underground; without which supply of food, and the flocks of wild fowl that at the same time cover the creeks and lagoons, it is more than probable, the first navigators of the Murray would not have heard a human voice along its banks; but so it is, that in the wide field of nature, we see the hand of an over-ruling Providence, evidences of care and protection from some unseen quarter, which strike the mind with overwhelming conviction, that whether in the palace or in the cottage, in the garden, or in the desert, there is an eye upon us. Not to myself do I accord any credit in that I returned from my wanderings to my home. Assuredly, if it had not been for other guidance than the exercise of my own prudence, I should have perished: and I feel satisfied the reader of these humble pages, will think as I do when he shall have perused them.
An inspection of the accompanying chart, will shew that the course of the Murray, as far as the 138 degrees meridian is to the W.N.W., but that, at that point, it turns suddenly to the south, and discharges itself into Lake Victoria, which again communicates with the ocean, in the bight of Encounter Bay. This outlet is called the "Sea mouth of the Murray," and immediately to the eastward of it, is the Sand Hill, now called Barker's Knoll--under which the excellent and amiable officer after whom it is named fell by the hands of the natives, in the cause of geographical research.
Running parallel with its course from the southerly bend, or great N.W. angle of the Murray, there is a line of hills, terminating southwards, at Cape Jarvis; but, extending northwards beyond the head of Spencer's Gulf. These hills contain the mineral wealth of South Australia, and immediately to the westward of them is the fair city of Adelaide.
On gaining the level interior, the Murray passes through a desert country to the 140 degrees meridian, when it enters the great fossil formation, of which I shall have to speak hereafter. In lat. 34 degrees, and in long. 142 degrees, the Darling forms a junction with it; consequently, as that river rises in latitude 27 degrees, and in long. 152 degrees, its direct course will be about S.W. There is a distance of nine degrees of latitude, therefore, between their respective sources, and, as the Darling forms a considerable angle with the Murray at this junction, it necessarily follows, as I have had occasion to remark, that the two rivers must receive all the drainage from the eastward, falling into that angle. If I have been sufficiently clear in explaining the geographical position and character of these two rivers, which in truth almost make an island of the S.E. angle of the Australian continent, it will only remain for me to add in this place, that neither the Murray nor the Darling receive any tributary stream from the westward or northward, and at the time at which I commenced my last enterprise, the Darling was the boundary of inland discovery, if I except the journey of my gallant friend Eyre, to Lake Torrens, and the discovery by him of the country round Mount Serle. Sir Thomas Mitchell had traced the Darling, from the point at which I had been obliged from the want of good water to abandon it, in 1828, to lat. 32 degrees 26 minutes, and had marked down some hills to the westward of it. Still I do not think that I detract from his merit, and I am sure I do not wish to do so, when I say that his having so marked them can hardly be said to have given us any certain knowledge of the Cis-Darling interior.
More than sixteen years had elapsed from the period when I undertook the exploration of the Murray River, to that at which I commenced my preparations for an attempt to penetrate Central Australia. Desolate, however, as the country for the most part had been, through which I passed, my voyage down that river had been the forerunner of events I could neither have anticipated or foreseen. I returned indeed to Sydney, disheartened and dissatisfied at the result of my investigations. To all who were employed in that laborious undertaking, it had proved one of the severest trial and of the greatest privation; to myself individually it had been one of ceaseless anxiety. We had not, as it seemed, made any discovery to gild our enterprise, had found no approximate country likely to be of present or remote advantage to the Government by which we had been
