We could not gain any satisfactory information, as to the termination of the river, from these people. It was evident that some change was at hand; but what it was we could not ascertain.

APPEARANCE OF SOME APPROACHING CHANGE.

On the morning of the 9th, we left our fair friend and her lame husband, and proceeded down the river. The wind had moderated, although it still blew fresh. We ascended every height as we went along, but could not see any new feature in the country. Our view to the eastward was very confined; to the westward the interior was low and dark, and was backed in the distance by lofty ranges, parallel to which we had been running for some days. The right bank of the valley was beautifully undulated, but the left was bleak and bare. The valley had a breadth of from three to four miles, and the flats were more extensive under the former than under the latter. They were scarcely two feet above the level of the water, and were densely covered with reeds. As there was no mark upon the reeds to indicate the height to which the floods rose, I cannot think that these flats are ever wholly laid under water; if they are, it cannot be to any depth: at all events a few small drains would effectually prevent inundation. The soil upon the hills continued to be much mixed with sand, and the prevailing trees were cypress and box. Among the minor shrubs and gra.s.s, many common to the east coasts were noticed; and although the bold cliffs had ceased, the basis of the country still continued of the fossil formation. At a turn of the stream hereabouts, however, a solitary rock of coa.r.s.e red granite rose above the waters, and formed an island in its centre; but only in this one place was it visible. The rock was composed princ.i.p.ally of quartz and feldspar.

A little below it, we found a large tribe anxiously awaiting our arrival.

They crowded to the margin of the river with great eagerness, and evinced more surprise at our appearance than any tribe we had seen during the journey; but we left them very soon, notwithstanding that they importuned us much to stay.

After pulling a mile or two, we found a clear horizon before us to the south. The hills still continued upon our left, but we could not see any elevation over the expanse of reeds to our right. The river inclined to the left, and swept the base of the hills that still continued on that side. I consequently landed once more to survey the country.

TERMINATION OF THE MURRAY IN A LARGE LAKE.

I still retained a strong impression on my mind that some change was at hand, and on this occasion, I was not disappointed; but the view was one for which I was not altogether prepared. We had, at length, arrived at the termination of the Murray. Immediately below me was a beautiful lake, which appeared to be a fitting reservoir for the n.o.ble stream that had led us to it; and which was now ruffled by the breeze that swept over it.

The ranges were more distinctly visible, stretching from south to north, and were certainly distant forty miles. They had a regular unbroken outline; declining gradually to the south, but terminating abruptly at a lofty mountain northerly. I had no doubt on my mind of this being the Mount Lofty of Captain Flinders; or that the range was that immediately to the eastward of St. Vincent's Gulf--Since the accident to the chronometer, we had not made any westing, so that we knew our position as nearly as possible. Between us and the ranges a beautiful promontory shot into the lake, being a continuation of the right bank of the Murray. Over this promontory the waters stretched to the base of the ranges, and formed an extensive bay. To the N.W. the country was exceedingly low, but distant peaks were just visible over it. To the S.W. a bold headland showed itself; beyond which, to the westward, there was a clear and open sea visible, through a strait formed by this headland and a point projecting from the opposite sh.o.r.e. To the E. and S.E. the country was low, excepting the left sh.o.r.e of the lake, which was backed by some minor elevations, crowned with cypresses. Even while gazing on this fine scene, I could not but regret that the Murray had thus terminated; for I immediately foresaw that, in all probability, we should be disappointed in finding any practicable communication between the lake and the ocean, as it was evident that the former was not much influenced by tides. The wind had again increased; it still blew fresh from the S.W. and a heavy sea was rolling direct into the mouth of the river. I hoped, notwithstanding, that we should have been enabled to make sail, for which reason we entered the lake about 2 p.m. The natives had kindled a large fire on a distant point between us and the further headland, and to gain this point our efforts were now directed. The waves were, however, too strong, and we were obliged to make for the eastern sh.o.r.e, until such time as the weather should moderate. We pitched our tents on a low track of land that stretched away seemingly for many miles directly behind us to the eastward. It was of the richest soil, being a black vegetable deposit, and although now high above the influence, the lake had, it was evident, once formed a part of its bed. The appearance of the country altogether encouraged M'Leay and myself to walk out, in order to examine it from some hills a little to the S.E. of the camp. From them we observed that the flat extended over about fifty miles, and was bounded by the elevations that continued easterly from the left bank of the Murray to the north, and by a line of rising-ground to the south. The whole was lightly wooded, and covered with gra.s.s. The season must have been unusually dry, judging from the general appearance of the vegetation, and from the circ.u.mstance of the lagoons in the interior being wholly exhausted.

Thirty-three days had now pa.s.sed over our heads since we left the depot upon the Morumbidgee, twenty-six of which had been pa.s.sed upon the Murray.

We had, at length, arrived at the grand reservoir of those waters whose course and fate had previously been involved in such obscurity. It remained for us to ascertain whether the extensive sheet of water upon whose bosom we had embarked, had any practicable communication with the ocean, and whether the country in the neighbourhood of the coast corresponded with that immediately behind our camp, or kept up its sandy and sterile character to the very verge of the sea. As I have already said, my hopes on the first of these points were considerably damped, but I could not help antic.i.p.ating a favourable change in the latter, since its features had so entirely changed.

DETAINED BY THE WIND.

The greatest difficulty against which we had at present to contend was the wind; and I dreaded the exertion it would call for, to make head against it; for the men were so much reduced that I felt convinced they were inadequate to any violent or prolonged effort. It still blew fresh at 8 p.m., but at that time it began to moderate. It may be imagined that I listened to its subdued gusts with extreme anxiety. It did not wholly abate until after 2 a.m., when it gradually declined, and about 3 a light breeze sprung up from the N. E.

We had again placed sticks to ascertain with more precision the rise of tide, and found it to be the same as in the river. In the stillness of the night too we thought we heard the roaring of the sea, but I was myself uncertain upon the point, as the wind might have caused the sound.

From the top of the hill from which we had obtained our first view of the lake, I observed the waves breaking upon the distant headland, and enveloping the cliff in spray; so that, independent of the clearness of the horizon beyond it, I was further led to conclude that there existed a great expanse of water to the S.W.; and, as that had been the direction taken by the river, I thought it probable that by steering at once to the S.W. down the lake, I should hit the outlet. I, consequently, resolved to gain the southern extremity of the lake, as that at which it was natural to expect a communication with the ocean would be found.

GEOLOGICAL FORMATION.

At 4 we had a moderate breeze, and it promised to strengthen; we lost no time therefore in embarking, and with a flowing sheet stretched over to the W.S.W., and ran along the promontory formed by the right bank of the Murray. We pa.s.sed close under its extreme point at nine. The hills had gradually declined, and we found the point to be a flat, elevated about thirty feet above the lake. It was separated from the promontory by a small channel that was choked up with reeds, so that it is more than probable that the point is insulated at certain periods; whilst in its stratification it resembled the first cliffs I have described that were pa.s.sed below the Darling. It is a remarkable fact in the geology of the Murray, that such should be the case; and that the formation at each extremity of the great bank or bed of fossils should be the same.

Thus far, the waters of the lake had continued sweet; but on filling a can when we were abreast of this point, it was found that they were quite unpalatable, to say the least of them. The transition from fresh to salt water was almost immediate, and it was fortunate we made the discovery in sufficient time to prevent our losing ground. But, as it was, we filled our casks, and stood on, without for a moment altering our course.

Pa.s.sAGE ACROSS THE LAKE--ITS SHALLOWNESS.

It is difficult to give a just description of our pa.s.sage across the lake.

The boisterous weather we had had seemed to have blown over. A cool and refreshing breeze was carrying us on at between four and five knots an hour, and the heavens above us were without a cloud. It almost appeared as if nature had resisted us in order to try our perseverance, and that she had yielded in pity to our efforts. The men, relieved for a time from the oar, stretched themselves at their length in the boat, and commented on the scenery around them, or ventured their opinions as to that which was before them. Up to this moment their conduct had been most exemplary; not a murmur had escaped from them, and they filled the water-casks with the utmost cheerfulness, even whilst tasting the disagreeable beverage they would most probably have to subsist on for the next three or four days.

As soon as we had well opened the point, we had a full view of the splendid bay that, commencing at the western most of the central points, swept in a beautiful curve under the ranges. No land was visible to the W.N.W. or to the S.S.W.: in both these quarters the lake was as open as the ocean. It appeared, therefore, that the land intermediate was an island. To the north the country was extremely low, and as we increased our distance from it we lost sight of it altogether. At noon we were nearly abreast of the eastern headland, or in the centre of the strait to which I have alluded. At this time there was an open sea from W.N.W. to N. by E. A meridian alt.i.tude gave our lat.i.tude 35 degrees 25 minutes.

The land to our left was bold and precipitous; that to the right was low and wooded; and there was evidently a considerable s.p.a.ce between the sh.o.r.es of the lake and the base of the ranges. The country to the eastward was hidden from us by the line of cliffs, beyond which from E.S.E. to W.S.W. there was an open sea. We had kept the lead going from the first, and I was surprised at the extreme shallowness of the lake in every part, as we never had six feet upon the line. Its bottom was one of black mud, and weeds of enormous length were floating on its surface, detached by the late gales, and which, from the shallowness of the lake, got constantly entangled with our rudder.

We tried to land on the eastern point, but found the water too shallow, and were obliged to try the western sh.o.r.e. In pa.s.sing close under the head, we observed several natives upon it, who kindled a large fire as soon as they saw they were noticed, which was answered from every point; for, in less than ten minutes afterwards, we counted no fewer than fourteen different fires, the greater number of which were on the side of the ranges.

Sh.o.r.eS OF THE LAKE.

As we were standing across from one sh.o.r.e to the other, our attention was drawn to a most singular object. It started suddenly up, as above the waters to the south, and strikingly resembled an isolated castle. Behind it, a dense column of smoke rose into the sky, and the effect was most remarkable. On a nearer approach, the phantom disappeared and a clear and open sea again presented itself to our view. The fact was, that the refractive power upon the coast had elevated the sand-hillocks above their true position, since we satisfactorily ascertained that they alone separated the lake from the ocean, and that they alone could have produced the semblance we noticed. It is a singular fact, that this very hillock was the one which Capt. Barker ascended whilst carrying on the survey of the south coast, and immediately previous to his tragical death.

It was not without difficulty that we succeeded in landing on the western sh.o.r.e; but we did, at length, succeed, and prepared our dinners. The sh.o.r.e was low, but above the reach of all floods; the soil was rich, and superficially sandy. It was covered with high gra.s.ses, and abounded in kangaroos; within the s.p.a.ce of a few yards we found five or six, but they were immediately lost to us and to the dogs in the luxuriance of the vegetation amidst which they were feeding.

As soon as we had finished our meal, we once more embarked, and stood along the sh.o.r.e to the S.W., but the lake was so shoal, that I was every moment apprehensive we should ground. I ran across, therefore, to the south, towards a low flat that had just appeared above the line of the horizon, in hope that, in sounding, we should have found the channel, but there either was none, or else it was so narrow that we pa.s.sed over it between the heaves of the lead. At this time, the western sh.o.r.e was quite distinct, and the scenery was beautiful.

The flat we were approaching was a mud-flat, and, from its appearance, the tide was certainly at the ebb. We observed some cradles, or wicker frames, placed far below high water-mark, that were each guarded by two natives, who threatened us violently as we approached. In running along the land, the stench from them plainly indicated what they were which these poor creatures were so anxiously watching.

We steered a S.W. course, towards some low and wooded hills, pa.s.sing a rocky island, and found that we had struck the mouth of a channel running to the W.S.W. It was about half-a-mile wide, was bounded to the right by some open flat ground, and to the left by a line of hills of about sixty or seventy feet in elevation, partly open and partly covered with beefwood.

WARLIKE DEMEANOUR OF THE NATIVES.

Upon the first of these hills, we observed a large body of natives, who set up the most terrific yells as we approached. They were fully equipped for battle and, as we neared the sh.o.r.e, came down to meet us with the most violent threats. I wished much to communicate with them, and, not without hopes of quieting them, stood right in with the intention of landing.

I observed, however, that if I did so, I should have to protect myself.

I hauled a little off, and endeavoured, by holding up a branch and a tomahawk, to gain their confidence, but they were not to be won over by my show of pacification. An elderly man walked close to the water's edge unarmed, and, evidently, directed the others. He was followed by seven or eight of the most daring, who crept into the reeds, with their spears shipped to throw at us. I, therefore, took up my gun to return their salute. It then appeared that they were perfectly aware of the weapon I carried, for the moment they saw it, they dashed out of their hiding place and retreated to the main body; but the old man, after saying something to them, walked steadily on, and I, on my part, laid my firelock down again.

LOVELY EVENING.

It was now near sunset; and one of the most lovely evenings I had ever seen. The sun's radiance was yet upon the mountains, but all lower objects were in shade. The banks of the channel, with the trees and the rocks, were reflected in the tranquil waters, whose surface was unruffled save by the thousands of wild fowl that rose before us, and made a noise as of a mult.i.tude clapping hands, in their clumsy efforts to rise from the waters.

Not one of them allowed us to get within shot.

We proceeded about a mile below the hill on which the natives were posted; some few still following us with violent threats. We landed, however, on a flat, bounded all round by the continuation of the hills. It was an admirable position, for, in the centre of it, we could not be taken by surprise, and, on the other hand, we gave the natives an opportunity of communicating with us if they would. The full moon rose as we were forming the camp, and, notwithstanding our vicinity to so noisy a host, the silence of death was around us, or the stillness of the night was only broken by the roar of the ocean, now too near to be mistaken for wind, or by the silvery and melancholy note of the black swans as they pa.s.sed over us, to seek for food, no doubt, among the slimy weeds at the head of the lake. We had been quite delighted with the beauty of the channel, which was rather more than half-a-mile in width. Numberless mounds, that seemed to invite civilised man to erect his dwelling upon them, presented themselves to our view. The country round them was open, yet ornamentally wooded, and rocks and trees hung or drooped over the waters.

EXTENT OF THE LAKE.

We had in one day gained a position I once feared it would have cost us infinite labour to have measured. Indeed, had we been obliged to pull across the lake, unless during a calm, I am convinced the men would have been wholly exhausted. We had to thank a kind Providence that such was not the case, since it had extended its mercy to us at so critical a moment.

We had indeed need of all the little strength we had remaining, and could ill have thrown it away on such an effort as this would have required.

I calculated that we could not have run less than forty-five miles during the day, a distance that, together with the eight miles we had advanced the evening previously, would give the length of the lake at fifty-three miles.

We had approached to within twelve miles of the ranges, but had not gained their southern extremity. From the camp, Mount Barker bore nearly north.

The ranges appeared to run north and south to our position, and then to bend away to the S.S.W., gradually declining to that point, which I doubted not terminated in Cape Jervis. The natives kept aloof during the night, nor did the dogs by a single growl intimate that any had ventured to approach us. The sound of the surf came gratefully to our ears, for it told us we were near the goal for which we had so anxiously pushed, and we all of us promised ourselves a view of the boundless ocean on the morrow.

CHANNEL TO THE SEA--ITS SHALLOWNESS.

As the morning dawned, we saw that the natives had thrown an out-post of sixteen men across the channel, who were watching our motions; but none showed themselves on the hills behind us, or on any part of the south sh.o.r.e. We embarked as soon as we had breakfasted, A fresh breeze was blowing from the N.E. which took us rapidly down the channel, and our prospects appeared to be as cheering as the day, for just as we were about to push from the sh.o.r.e, a seal rose close to the boat, which we all regarded as a favourable omen. We were, however, shortly stopped by shoals; it was in vain that we beat across the channel from one side to the other; it was a continued shoal, and the deepest water appeared to be under the left bank. The tide, however, had fallen, and exposed broad flats, over which it was hopeless, under existing circ.u.mstances, to haul the boat. We again landed on the south side of the channel, patiently to await the high water.

M'Leay, myself, and Fraser, ascended the hills, and went to the opposite side to ascertain the course of the channel, for immediately above us it turned south round the hills. We there found that we were on a narrow tongue of land. The channel was immediately below us, and continued to the E.S.E. as far as we could trace it. The hills we were upon, were the sandy hills that always bound a coast that is low, and were covered with banksias, casuarina and the gra.s.s-tree.

To the south of the channel there was a flat, backed by a range of sand-hummocks, that were covered with low shrubs; and beyond them the sea was distinctly visible. We could not have been more than two and a half miles from the beach where we stood.

Notwithstanding the sandy nature of the soil, the fossil formation again showed itself, not only on these hills, but also on the rocks that were in the channel.

A little before high water we again embarked. A seal had been observed playing about, and we augured well from such an omen. The blacks had been watching us from the opposite sh.o.r.e, and as soon as we moved, rose to keep abreast of us. With all our efforts we could not avoid the shoals. We walked up to our knees in mud and water, to find the least variation in the depth of the water so as to facilitate our exertions, but it was to no purpose. We were ultimately obliged to drag the boat over the flats; there were some of them a quarter of a mile in breadth, knee-deep in mud; but at length got her into deep water again. The turn of the channel was now before us, and we had a good run for about four or five miles. We had completed the bend, and the channel now stretched to the E.S.E. At about nine miles from us there was a bright sand-hill visible, near which the channel seemed to turn again to the south; and I doubted not that it terminated there. It was to no purpose, however, that we tried to gain it.

Shoals again closed in upon us on every side. We dragged the boat over several, and at last got amongst quicksands. I, therefore, directed our efforts to hauling the boat over to the south side of the channel, as that on which we could most satisfactorily ascertain our position. After great labour we succeeded, and, as evening had closed in, lost no time in pitching the tents.

BEACH OF ENCOUNTER BAY.

While the men were thus employed, I took Fraser with me, and, accompanied by M'Leay, crossed the sand-hummocks behind us, and descended to the sea-sh.o.r.e. I found that we had struck the south coast deep in the bight of Encounter Bay. We had no time for examination, but returned immediately to the camp, as I intended to give the men an opportunity to go to the beach. They accordingly went and bathed, and returned not only highly delighted at this little act of good nature on my part, but loaded with c.o.c.kles, a bed of which they had managed to find among the sand. Clayton had tied one end of his shirt up, and brought a bag full, and amused himself with boiling c.o.c.kles all night long.

If I had previously any hopes of being enabled ultimately to push the boat over the flats that were before us, a view of the channel at low water, convinced me of the impracticability of any further attempt. The water was so low that every shoal was exposed, and many stretched directly from one side of the channel to the other; and, but for the treacherous nature of the sand-banks, it would not have been difficult to have walked over dry footed to the opposite side of it. The channel stretched away to the E.S.E., to a distance of seven or eight miles, when it appeared to turn south under a small sand-hill, upon which the rays of the sun fell, as it was sinking behind us.

CURIOUS EFFECT OF REFRACTION.

There was an innumerable flock of wild-fowl arranged in rows along the sides of the pools left by the tide, and we were again amused by the singular effect of the refraction upon them, and the grotesque and distorted forms they exhibited. Swans, pelicans, ducks, and geese, were mingled together, and, according to their distance from us, presented different appearances. Some were exceedingly tall and thin, others were unnaturally broad. Some appeared reversed, or as if they were standing on their heads, and the slightest motion, particularly the flapping of their wings, produced a most ridiculous effect. No doubt, the situation and the state of the atmosphere were favourable to the effect I have described.

The day had been fine, the evening was beautiful,--but it was the rarefaction of the air immediately playing on the ground, and not the haze at sunset that caused what I have noticed. It is distinct from mirage, although it is difficult to point out the difference. The one, however, distorts, the other conceals objects, and gives them a false distance. The one is clear, the other is cloudy. The one raises objects above their true position, the other does not. The one plays about, the other is steady; but I cannot hope to give a proper idea either of mirage or refraction so satisfactorily as I could wish. Many travellers have dwelt upon their effects, particularly upon those of the former, but few have attempted to account for them.
