Continuing the line of coast to the westward, the expedition passed through the most wretched and desolate country imaginable, consisting almost entirely of a table-land, or of undulating ridges, covered for the most part with dense scrubs, and almost wholly without either grass or water. The general elevation of this country was from three to five hundred feet, and all of the tertiary deposit, with primary rocks protruding at intervals.
The first permanent fresh water met with on the surface was a small fresh-water lake, beyond the parallel of 123 degrees E.; but from Mount Arden to that point, a distance of fully 800 miles in a direct line, none whatever was found on the surface (if I except a solitary small spring sunk in the rock at Streaky Bay). During the whole of this vast distance, not a watercourse, not a hollow of any kind was crossed; the only water to be obtained was by digging close to the sea-shore, or the sand-hills of the coast, and even by that means it frequently could not be procured for distances of 150 to 160 miles together. With the exception of the Gawler Range, which lies between Streaky Bay and Mount Arden, this dreary waste was one almost uniform table-land of fossil formation, with an elevation of from three to five hundred feet, covered for the most part by dense impenetrable scrubs, and varied only on its surface by occasional sandy or rocky undulations.
What then can be the nature of that mysterious interior, bounded as it is by a table-land without river or lakes, without watercourses or drainage of any kind, for so vast a distance? Can it be that the whole is one immense interminable desert, or an alternation of deserts and shallow salt lakes like Lake Torrens? Conjecture is set at defiance by the impenetrable arrangements of nature; where, the more we pry into her secrets, the more bewildered and uncertain become all our speculations.
It has been a common and a popular theory to imagine the existence of an inland sea, and this theory has been strengthened and confirmed by the opinion of so talented, so experienced, and so enterprising a traveller as my friend Captain Sturt, in its favour. That gentleman, with the noble and disinterested enthusiasm by which he has ever been characterised, has once more sacrificed the pleasure and quiet of domestic happiness, at the shrine of enterprise and science. With the ardour of youth, and the perseverance and judgment of riper years, he is even now traversing the trackless wilds, and seeking to lift up that veil which has hitherto hung over their recesses. May he be successful to the utmost of his wishes, and may he again rejoin in health and safety his many friends, to forget in their approbation and admiration the toils he has encountered, and to enjoy the rewards and laurels which will have been so hardly earned, and so well deserved.
It was in August, 1844, that Captain Sturt set out upon his arduous undertaking, with a numerous and well equipped party, and having provisions calculated to last them for eighteen months. I had the pleasure of accompanying the expedition as far as the Rufus (about 240 miles from Adelaide), to render what assistance I could, in passing up, on friendly terms among the more distant natives of the Murray. Since my return, Captain Sturt has been twice communicated with, and twice heard from, up to the time I left the Colony, on the 21st December, 1844. The last official communication addressed to the Colonial Government will be found in Chapter IX. of Notes on the Aborigines. The following is a copy of a private letter to John Morphett, Esq M.C., and published in the Adelaide Observer of the 9th November, 1844:—
"14th October, 1844.
"I left Lake Victoria, as I told you in a former letter, on the 18th of September, and again cut across the country to the Murray. As we travelled along we saw numerous tracks of wild cattle leading from the marshes to the river, and we encamped at the junction of the river and a lagoon (one of the most beautiful spots you ever saw), just where these tracks were most numerous. In the night therefore we were surrounded by lowing herds, coming to the green pastures of which we had taken possession. In the morning I sent Messrs. Poole and Brown, with Flood my stockman, and Mark to drive in some bullocks, as I was anxious to secure one or two workers. The brush however was too thick, and in galloping through it after a bull, Flood's carbine exploded, and blew off three of the fingers of his right hand. This accident obliged me to remain stationary for two days, notwithstanding my anxiety to get up to the lagoon at Williorara, to ascertain the truth or otherwise of the report I had heard of the massacre of a party of overlanders there.
"On the 23rd I reached the junction of the Ana branch with the Murray, discovered by Eyre, and then turned northwards. Running this Ana branch up, I crossed it where the water ceased, and went to the Darling, striking it about fifteen miles above its junction with the Murray. The unlooked-for course of the Darling however kept me longer on its banks than I had anticipated; but you can form no idea of the luxuriant verdure of its flats. They far surpass those of the Murray, both in quantity and quality of soil; and extended for many miles at a stretch along the river side. We have run up it at a very favourable season, and seen the commencement of its floods; for, two days after we reached it, and found it with scarcely any water in its bed, we observed a fresh in it, indicated by a stronger current. The next morning to our surprise the waters were half-bank high. They had risen six feet during the night, and were carrying everything before them; now they are full sixteen feet above their level, and a most beautiful river it is. Over this said mysterious river, as Major Mitchell calls it, the trees drooped like willows, or grew in dark clusters at each turn; the sloping banks were of a vivid green, the flats lightly timbered, and the aspect of the whole neighbourhood cheerful.
"I had hoped that we should have been able to approach the ranges pretty closely along the line of Laidley's Ponds; but fancy our disappointment when we arrived on its banks to find that instead of a mountain stream it was a paltry creek, connecting a lake, now dry, with the river, and that its banks were quite bare. I was therefore obliged to fall back upon the Darling, and have been unable to stir for the last four days by reason of heavy rain.
"On Tuesday I despatched Mr. Poole to the ranges, which are forty miles distant from us, to ascertain if there is water or feed under them; but I have no hope of good tidings, and believe I shall ultimately be obliged to establish myself on the Darling.
