Immediately beneath was the low region from which we had just ascended2, occupying the line of the horizon from the north-east point, southwards, round to the west. Southward, and for some degrees on either side, a fine dark line met the sky; but to the north-east and south-west was a boundless3 extent of earthy plain. Here and there a solitary4 clump5 of trees appeared, and on the plain, at the distance of a mile to the eastward6, were two moving specks7, in the shape of native women gathering8 roots, but they saw us not, neither did we disturb them — their presence indicated that even these gloomy and forbidding regions were not altogether uninhabited.
As the reader will, I have no doubt, remember, the sandy ridges9 on the S.E. side of the Desert were running at an angle of about 18 degrees to the west of north, having gradually changed from the original direction of about 6 degrees to the eastward of that point. I myself had marked this gradual change with great interest, because it was strongly corroborative10 of my views as to the course the current I have supposed to have swept over the central parts of the continent must have taken, i. e. a course at right angles to the ridges. It is a remarkable11 fact that here, on the northern side of the Desert, and after an open interval12 of more than 50 miles, the same sand ridges should occur, running in parallel lines at the same angle as before, into the very heart of the interior, as if they absolutely were never to terminate. Here, on both sides of us, to the eastward and to the westward13, they followed each other like the waves of the sea in endless succession, suddenly terminating as I have already observed on the vast plain into which they ran. What, I will ask, was I to conclude from these facts? — that the winds had formed these remarkable accumulations of sand, as straight as an arrow lying on the ground without a break in them for more than ninety miles at a stretch, and which we had already followed up for hundreds of miles, that is to say across six degrees of latitude14? No! winds may indeed have assisted in shaping their outlines, but I cannot think, that these constituted the originating cause of their formation. They exhibit a regularity15 that water alone could have given, and to water, I believe, they plainly owe their first existence. It struck me then, and calmer reflection confirms the impression, that the whole of the low interior I had traversed was formerly16 a sea-bed, since raised from its sub-marine position by natural though hidden causes; that when this process of elevation17 so changed the state of things, as to make a continuous continent of that, which had been an archipelago of islands, a current would have passed across the central parts of it, the direction of which must have been parallel to the sandy ridges, and consequently from east to west, or nearly so — that also being the present dip of the interior, as I shall elsewhere prove. I further think, that the line of the Stony18 Desert being the lowest part of the interior, the current must there have swept along it with greater force, and have either made the breach19 in the sandy ridges now occupied by it, or have prevented their formation at the time when, under more favourable20 circumstances, they were thrown up on either side of it. I do not know if I am sufficiently21 clear in explanation, finding it difficult to lay down on paper all that crowds my own mind on this subject; neither can I, without destroying the interest my narrative22 may possess, now bring forward the arguments that gradually developed themselves in support of the foregoing hypothesis.
Although I had been unable to penetrate23 to the north-west of Lake Torrens, that basin appeared to me to have once formed part of the back waters of Spencer’s Gulf24; still I long kept in view the possibility of its being connected with some more central body of water. Having however gained a position so much higher to the north, and almost on the same meridian25, and having crossed so remarkable a feature as the Stony Desert (which, as I suppose, was once the focus of a mighty26 current, to judge from its direction passing to the westward), I no longer encouraged hopes which, if realized, would have been of great advantage to me, or regretted the circumstances by which I was prevented from more fully27 examining the north-east and northern shores of Lake Torrens. I felt doubtful of the immediate1 proximity28 of an inland sea, although many circumstances combined to strengthen the impression on my mind that such a feature existed on the very ground over which we had made our way. I had assuredly put great credit on the statements of the solitary old man who visited the Depot29, but his information as far as we could judge had turned out to be false; and I was half angry with myself for having been so credulous30, well aware as I was of the exaggerations of the natives, and how little dependence31 can be placed on what they say.
