Two Expeditions into the Interior of Southern Australia Part 7

Beneath us, to the westward, I observed a broad and thinly wooded valley; and W. by S., distant apparently about twenty miles, an isolated mountain, whose sides seemed almost perpendicular, broke the otherwise even line of the horizon; but the country in every other direction looked as if it was darkly wooded. Antic.i.p.ating that I should find a stream in the valley, I did not for a moment hesitate in striking down into it. Disappointed, however, in this expectation, I continued onwards to the mountain, which I reached just before the sun set. Indeed, he was barely visible when I gained its summit; but my eyes, from exposure to his glare, became so weak, my face was so blistered, and my lips cracked in so many places, that I was unable to look towards the west, and was actually obliged to sit down behind a rock until he had set.

Perhaps no time is so favourable for a view along the horizon as the sunset hour; and here, at an elevation of from five to six hundred feet above the plain, the visible line of it could not have been less than from thirty-five to forty-five miles. The hill upon which I stood was broken into two points; the one was a bold rocky elevation; the other had its rear face also perpendicular, but gradually declined to the north, and at a distance of from four to five miles was lost in an extensive and open plain in that direction. In the S.E. quarter, two wooded hills were visible, which before had appeared to be nothing more than swells in the general level of the country. A small hill, similar to the above, bore N.E. by compa.s.s; and again, to the west, a more considerable mountain than that I had ascended, and evidently much higher, reflected the last beams of the sun as he sunk behind them. I looked, however, in vain for water.

I could not trace either the windings of a stream, or the course of a mountain torrent; and, as we had pa.s.sed a swamp about a mile from the hill, we descended to it for the night, during which we were grievously tormented by the mosquitoes.

RESULTS OF THE EXCURSION.

I had no inducement to proceed further into the interior. I had been sufficiently disappointed in the termination of this excursion, and the track before me was still less inviting. Nothing but a dense forest, and a level country, existed between me and the distant hill. I had learnt, by experience, that it was impossible to form any opinion of the probable features of so singular a region as that in which I was wandering, from previous appearances, or to expect the same result, as in other countries, from similar causes. In a geographical point of view, my journey had been more successful, and had enabled me to put to rest for ever a question of much previous doubt. Of whatever extent the marshes of the Macquarie might be, it was evident they were not connected with those of the Lachlan. I had gained knowledge of more than 100 miles of the western interior, and had ascertained that no sea, indeed that little water, existed on its surface; and that, although it is generally flat, it still has elevations of considerable magnitude upon it.

Although I had pa.s.sed over much barren ground, I had likewise noticed soil that was far from poor, and the vegetation upon which in ordinary seasons would, I am convinced, have borne a very different aspect.

Yet, upon the whole, the s.p.a.ce I traversed is unlikely to become the haunt of civilized man, or will only become so in isolated spots, as a chain of connection to a more fertile country; if such a country exist to the westward.

The hill which thus became the extreme of my journey, is of sandstone formation, and is bold and precipitous. Its summit is level and lightly timbered. As a tribute of respect to the late Surveyor-General, I called it Oxley's Table Land, and I named the distant hills D'Urban's Group, after Sir Benjamin D'Urban, in compliance with a previous request of my friend Lieut. De la Condamine, that I would so name any prominent feature of the interior that I might happen to come upon.

RETURN TO THE CAMP.

In returning to the camp, I made a circuit to the N.E., and reached the Macquarie late on the evening of the 5th of January; having been absent six days, during which we could not have ridden less than 200 miles. Yet the horses were not so fatigued as it was natural to expect they would have been.

My servant informed me that a party of natives had visited the camp on the 3rd, but that they retired precipitately on seeing the animals. I regretted to find the men but little better than when I left them. Several still complained of a painful irritation of the eyes, and of great weakness of sight. Attributing their continued indisposition in some measure to our situation, I was anxious to have moved from it; but as Mr.

Hume was still absent, I could not decide upon the measure. He made his appearance, however, on the 6th, having ridden the greater part of the day through rain, which commenced to fall in the morning. Soon after his arrival, Dawber, my overseer of animals, who had accompanied him, was taken suddenly ill. During the night he became much worse, with s.h.i.+vering and spasms, and on the following morning he was extremely weak and feverish. To add to my anxiety, Mr. Hume also complained of indisposition.

His state of health made me the more anxious to quit a position which I fancied unwholesome, and in which, if there was no apparent, there was certainly some secret, exciting cause; and as Mr. Hume reported having crossed a chain of ponds about four miles to the eastward, and out of the immediate precincts of the marshes, I ordered the tents to be struck, and placing Dawber on my horse, we all moved quietly over to them.

MR. HUME'S EXCURSION.

The result of Mr. Hume's journey perplexed me exceedingly. He stated, that on setting out from the Macquarie his intention was to have proceeded to the N.E., to ascertain how far the reeds existed in that direction, and, if at all practicable, to reach the Castlereagh; but in case of failure, to regain the Macquarie by a westerly course. At first he travelled nearly four miles east, to clear the marshes, when he came on the chain of ponds to which we had removed.

He travelled over good soil for two miles after crossing this chain of ponds, but afterwards got on a red sandy loam, and found it difficult to proceed, by reason of the thickness of the brush, and the swampy state of the ground in consequence of the late rain.

The timber in the brushes was of various kinds, and he saw numerous kangaroos and emus. On issuing from this brush, he crossed a creek, leading northerly, the banks of which were from ten to twelve feet high.

Whatever the body of water usually in it is, it now only afforded a few shallow puddles. Mr. Hume travelled through brushes until he came upon a third creek, similar to the one he had left behind him, at which he halted for the night. The water in it was bad, and the feed for the animals extremely poor. The brush lined the creek thickly, and consisted chiefly of acacia pendula and box. The country preserved an uniform level, nor did Mr. Hume, from the highest trees, observe any break on the horizon.

On the 2nd of January, Mr. Hume kept more northerly, being unable to penetrate the brushes he encountered. At two miles he crossed a creek leading to the N.W., between which and the place at which he had slept, he pa.s.sed a native burial ground, containing eight graves. The earth was piled up in a conical shape, but the trees were not carved over as he had seen them in most other places.

The country became more open after he had pa.s.sed the last mentioned creek, which he again struck upon at the distance of eight miles, and as it was then leading to the N.N.E. he followed it down for eighteen or twenty miles, and crossed it frequently during the day. The creek was dry in most places, and where he stopped for the night the water was bad, and the cattle feed indifferent.

Mr. Hume saw many huts, but none of them had been recently occupied, although large quant.i.ties of muscle-sh.e.l.ls were scattered about. He computed that he had travelled about thirty miles, in a N.N.W.

direction, and the whole of the land he pa.s.sed over was, generally speaking, bad, nor did it appear to be subject to overflow.

On the 3rd, Mr. Hume proceeded down the creek on which he had slept, on a northern course, under an impression that it would have joined the Castlereagh, but it took a N.W. direction after he had ridden about four miles, and then turned again to the eastward of north. In consequence of this, he left it, and proceeded to the westward, being of opinion that the river just mentioned must have taken a more northerly course than Mr.

Oxley supposed it to have done.

A short time after Mr. Hume turned towards the Macquarie, the country a.s.sumed a more pleasing appearance. He soon cleared the brushes, and at two miles came upon a chain of ponds, again running northerly in times of flood. Shortly after crossing these, he found himself on an extensive plain, apparently subject to overflow. The timber on it was chiefly of the blue-gum kind, and the ground was covered with sh.e.l.ls. He then thought he was approaching the Macquarie, and proceeded due west across the flat for about two miles. At the extremity of it there was a hollow, which he searched in vain for water. Ascending about thirty feet, he entered a thick brush of box and acacia pendula, which continued for fourteen miles, when it terminated abruptly, and extensive plains of good soil commenced, stretching from N. to S. as far as the eye could reach, on which there were many kangaroos. Continuing to journey over them, he reached a creek at 5 p.m. on which the wild fowl were numerous, running nearly north and south, and he rested on its banks for the night. The timber consisted both of blue and rough gum, and the soil was a light earth.

Mr. Hume expected in the course of the day to have reached the Macquarie, but on arriving at the creek, he began to doubt whether it any longer existed, or whether it had not taken a more westerly direction. On the following morning, therefore, he crossed the creek, and travelled W.S.W., for about two miles over good plains; then through light brushes of swamp-oak, cypress, box, and acacia pendula, for about twelve miles, to another creek leading northerly. He shortly afterwards ascended a range of hills stretching W.N.W. to which he gave the name of New Year's Range.

From these hills, he had an extensive view, although not upon the highest part, but the only break he could see in the horizon was caused by some hills bearing by compa.s.s W. by S. distant about twenty-five miles. There was, however, an appearance as of high land to the northward, although Mr.

Hume thought it might have been an atmospheric deception. From the range he looked in vain for the Macquarie, or other waters, and, as his provisions were nearly consumed, he was obliged to give up all further pursuit, and to retrace his steps. He fell in with two parties of natives, which, taken collectively, amounted to thirty-five in number, but had no communication with them.

It was evident, from the above account, that supposing a line to have been drawn from the camp northerly, Mr. Hume must have travelled considerably to the westward of it, and as I had run on a N.W. course from the marshes, it necessarily followed that our lines of route must have intersected each other, or that want of extension could alone have prevented them from having done so; but that, under any circ.u.mstances, they could not have been very far apart. This was too important a point to be left undecided, as upon it the question of the Macquarie's termination seemed to depend.

Both Mr. Hume and myself were of opinion, that a medium course would be the most satisfactory for us to pursue, to decide this point; and it appeared that we could not do better than, by availing ourselves of the creek on which we were, and skirting the reeds, to take the first opportunity of das.h.i.+ng through them in a westerly direction.

DOUBTS OF THE FURTHER EXTENSION OF THE RIVER.

I entertained great doubts as to the longer existence of the river, and as I foresaw that, in the event of its having terminated we should strike at once into the heart of the interior, I became anxious for the arrival of supplies at Mount Harris; and although I could hardly expect that they had yet reached it, I determined to proceed thither. Mr. Hume was too unwell for me to think of imposing additional fatigue upon him; I left him, therefore, to conduct the party, by easy stages, to the northward, until such time as I should overtake them. Even in one day there was a visible improvement in the men, and Dawber's attack seemed to be rather the effects of cold than of any thing else. A death, however, under our circ.u.mstances, would have been so truly deplorable an event, that the least illness was sufficient to create alarm.

I can hardly say that I was disappointed on my arrival at Mount Harris, to find its neighbourhood silent and deserted. I remained, however, under it for the greater part of the next day, and, prior to leaving it, placed a sheet of paper with written instructions against a tree, though almost without a hope that it would remain untouched.

PERPLEXING SITUATION.

A little after sun-set we reached the first small marsh, at which we slept; and on the following morning I crossed the plains of the Macquarie, and joined the party at about fifteen miles from the creek at which I had left it. I found it in a condition that was as unlooked for by Mr. Hume as it was unexpected by me, and really in a most perplexing situation.

On the day I left him, Mr. Hume only advanced about two miles, in consequence of some derangement in the loads. Having crossed the creek, he, the next morning, proceeded down its right bank, until it entered the marshes and was lost. He then continued to move on the outskirts of the latter, and having performed a journey or about eight miles, was anxious to have stopped, but there was no water at hand. The men, however, were so fatigued, in consequence of previous illness, that he felt it necessary to halt after travelling about eleven miles.

No water could be procured even here, notwithstanding that Mr. Hume, who was quite unfit for great exertion, underwent considerable bodily fatigue in his anxiety to find some. He was, therefore, obliged to move early on the following morning, but neither men nor animals were in a condition to travel; and he had scarcely made three miles' progress, when he stopped and endeavoured to obtain a supply or water by digging pits among the reeds. From these he had drawn sufficient for the wants of the people when I arrived. Some rain had fallen on the 6th and 7th of the month, or it is more than probable the expedient to which he resorted would have failed of success. Mr. Hume, I was sorry to observe, looked very unwell; but nothing could prevent him from further endeavours to extricate the party from its present embarra.s.sment.

JOURNEY CONTINUED.

As soon as I had taken a little refreshment, therefore, I mounted a fresh horse; and he accompanied me across a small plain, immediately in front of the camp, which was subject to overflow and covered with polygonum, having a considerable extent of reeds to its right.

From the plain we entered a wood of blue-gum, in which reeds, gra.s.s, and brush formed a thick coppice. We at length pa.s.sed into an open s.p.a.ce, surrounded on every side by weeds in dense bodies. The great marsh bore south of us, and was clear and open, but behind us the blue-gum trees formed a thick wood above the weeds.

About two hundred yards from the outskirts of the marsh there was a line of saplings that had perished, and round about them a number of the tern tribe (sea swallow) were flying, one of which Mr. Hume had followed a considerable way into the reeds the evening before, in the hope that it would have led him to water. The circ.u.mstance of their being in such numbers led us to penetrate towards them, when we found a serpentine sheet of water of some length, over which they were playing. We had scarcely time to examine it before night closed in upon us, and it was after nine when we returned to the tents.

From the general appearance of the country to the northward, and from the circ.u.mstance of our having got to the bottom of the great marsh, which but a few days before had threatened to be so formidable, I thought it probable that the reeds would not again prove so extensive as they had been, and I determined, if I could do so, to push through them in a westerly direction from our position.

SECOND GREAT MARSH.

The pits yielded us so abundant a supply during the night, that in the morning we found it unnecessary to take the animals to water at the channel we had succeeded in finding the evening before; but pursuing a westerly course we pa.s.sed it, and struck deep into the reeds. At mid-day we were hemmed in by them on every side, and had crossed over numerous channels, by means of which the waters of the marshes are equally and generally distributed over the s.p.a.ce subject to their influence. Coming to a second sheet of water, narrower, but longer, as well as we could judge, than the first, we stopped to dine at it; and, while the men were resting themselves, Mr. Hume rode with me in a westerly direction, to ascertain what obstacles we still had to contend with. Forcing our way through bodies of reeds, we at length got on a plain, stretching from S.E. to N.W., bounded on the right by a wood of blue-gum, under which the reeds still extended, and on the left by a wood in which they did not appear to exist. Certain that there was no serious obstacle in our way, we returned to the men; and as soon as they had finished their meal, led them over the plain in a N.W. by W. direction. It was covered with sh.e.l.ls, and was full of holes from the effects of flood.

CONCLUSIONS IN REGARD TO THE MACQUARIE.

As we were journeying over it, I requested Mr. Hume to ride into the wood upon our left, to ascertain if it concealed any channel. On his return he informed me that he descended from the plain into a hollow, the bottom of which was covered with small sh.e.l.ls and bulrushes. He observed a new species of eucalypti, on the trunks of which the water-mark was three feet high. After crossing this hollow, which was about a quarter of a mile in breadth, he gained an open forest of box, having good gra.s.s under it; and, judging from the appearance of the country that no other channel could exist beyond him, and that he had ascertained sufficient for the object I had in view, he turned back to the plain. We stopped for the night under a wood of box, where the gra.s.s, which had been burnt down, was then springing up most beautifully green, and was relished exceedingly by the animals.

It was in consequence of our not having crossed any channel, while penetrating through the reeds, that could by any possible exaggeration have been laid down as the bed of the river, that I detached Mr. Hume; and the account he brought me at once confirmed my opinion in regard to the Macquarie, and I thenceforth gave up every hope of ever seeing it in its characteristic shape again.

Independently however of all circ.u.mstantial evidence, it was clear that the river had not re-formed at a distance of twenty-five miles to the north of us, since Mr. Hume had gone to the westward of that point, at about the same distance on his late journey, without having observed the least appearance of reeds or of a river. He had, indeed, noticed a hollow, which occasionally contained water, but he saw nothing like the bed of a permanent stream. I became convinced, also, from observation of the country through which we had pa.s.sed, that the sources of the Macquarie could not be of such magnitude as to give a constant flow to it as a river, and at the same time to supply with water the vast concavity into which it falls. In very heavy rains only could the marshes and adjacent lands be laid wholly under water, since the evaporation alone would be equal to the supply.

The great plains stretching for so many miles to the westward of Mount Harris, even where they were clear of reeds, were covered with sh.e.l.ls and the claws of cray-fish and their soil, although an alluvial deposit, was superficially sandy. They bore the appearance not only of frequent inundation, but of the floods having eventually subsided upon them. This was particularly observable at the bottom of the marshes. We did not find any acc.u.mulation of rubbish to indicate a rush of water to any one point; but numerous minor channels existed to distribute the floods equally and generally over every part of the area subject to them, and the marks of inundation and subsidence were everywhere the same. The plain we had last crossed, was, in like manner, covered with sh.e.l.ls, so that we could not yet be said to be out of the influence of the marshes; besides which we had not crossed the hollow noticed by Mr. Hume, which it was clear we should do, sooner or later.

SITUATION OF THE PARTY.

To have remained in our position would have been impossible, as there was no water either for ourselves or the animals; to have descended into the reeds again, for the purpose of carrying on a minute survey, would, under existing circ.u.mstances, have been imprudent. Our provisions were running short, and if a knowledge of the distant interior was to be gained, we had no time to lose. It was determined, therefore, to defer our further examination of the marshes to the period of our return; and to pursue such a course as would soonest and most effectually enable us to determine the character of the western interior.
