Two Expeditions into the Interior of Southern Australia Part 6

It was evident that this plain had been frequently under water, but it was difficult to judge from the marks on the trees to what height the floods had risen. The soil was an alluvial deposit, superficially sandy; and many sh.e.l.ls were scattered over its surface. To the south, the country appeared close and low; nor do I think we could have approached the river from that side, by reason of the huge belts of reeds that appeared to extend as far as the the eye could reach.

MEN ATTACKED WITH OPHTHALMIA.

The approach of night obliged us to return to the camp. On our arrival, we found that the state of Henwood and Williams would prevent our stirring for a day or two. Not only had they a return of inflammation, but several other of the men complained of a painful irritation of the eyes, which were dreadfully blood-shot and weak. I was in some measure prepared for a relapse in Henwood, as the exposure which he necessarily underwent on the plain was sufficient to produce that effect; but I now became apprehensive that the affection would run through the party.

Considering our situation in its different bearings, it struck me that the men who were to return to Wellington Valley with an account our our proceedings for the Governor's information, had been brought as far as prudence warranted. There was no fear of their going astray, as long as they had the river to guide them; but in the open country which we were to all appearance approaching, or amidst fields of reeds, they might wander from the track, and irrecoverably lose themselves. I determined, therefore, not to risk their safety, but to prepare my dispatches for Sydney, and I hoped most anxiously, that ere they were closed, all symptoms of disease would have terminated.

In the course of the day, however, Spencer, who was to return with Riley to Wellington Valley, became seriously indisposed, and I feared that he was attacked with dysentery. Indeed, I should have attributed his illness to our situation, but I did not notice any unusual moisture in the atmosphere, nor did any fogs rise from the river. I therefore the rather attributed it to exposure and change of diet, and treated him accordingly.

To my satisfaction, when I visited the men late in the evening, I found a general improvement in the whole of them. Spencer was considerably relieved, and those of the party who had inflammation of the eyes no longer felt that painful irritation of which they had before complained.

I determined, therefore, unless untoward circ.u.mstances should prevent it, to send Riley and his companion homewards, and to move the party without loss of time.

We had not seen any natives for many days, but a few pa.s.sed the camp on the opposite side of the river on the evening of the 25th. They would not, however, come to us; but fled into the interior in great apparent alarm.

DEPARTURE OF TWO MEN FOR WELLINGTON.

On the morning of the 26th, the men were sufficiently recovered to pursue their journey. Riley and Spencer left us at an early hour; and about 7 a.m. we pursued a N.N.W. course along the great plain I have noticed, starting numberless quails, and many wild turkeys, by the way. Leaving that part of the river on which Mr. Hume and I had touched considerably to the left, we made for the point of a wood, projecting from the river line of trees into the plain. The ground under us was an alluvial deposit, and bore all the marks of frequent inundation.

The soil was yielding, blistered, and uneven; and the claws of cray-fish, together with numerous small sh.e.l.ls, were every where collected in the hollows made by the subsiding of the waters, between broad belts of reeds and scrubs of polygonum.

CONSULTATION.

On gaining the point of the wood, we found an absolute check put to our further progress. We had been moving directly on the great body of the marsh, and from the wood it spread in boundless extent before us. It was evidently lower than the ground on which we stood; we had therefore, a complete view over the whole expanse; and there was a dreariness and desolation pervading the scene that strengthened as we gazed upon it.

Under existing circ.u.mstances, it only remained for us either to skirt the reeds to the northward, or to turn in again upon the river; and as I considered it important to ascertain the direction of the Macquarie at so critical and interesting a point, I thought it better to adopt the latter measure. We, accordingly, made for the river, and pitched our tents, as at the last station, in the midst of reeds.

There were two points at this time, upon which I was extremely anxious.

The first was as to the course of the river; the second, as to the extent of the marshes by which we had been checked, and the practicability of the country to the northward.

In advising with Mr. Hume, I proposed launching the boat, as the surest means of ascertaining the former, and he, on his part, most readily volunteered to examine the marshes, in any direction I should point out.

It was therefore, arranged, that I should take two men, and a week's provision with me in the boat down the river; and that he should proceed with a like number of men on an excursion to the northward.

After having given directions as to the regulations of camp during our absence, we separated, on the morning of the 26th for the first time, in furtherance of the objects each had in view.

BOAT EXCURSION.

In pulling down the river, I found that its channel was at first extremely tortuous and irregular, but that it held a general N.W. course, and bore much the same appearance as it had done since our descent from Mount Foster.

We had a laborious task in lifting the boat over the trunks of trees that had fallen into the channel of the river or that had been left by the floods, and at length we stove her in upon a sunken log. The injury she received was too serious not to require immediate repair; and we, therefore, patched her up with a tin plate. This accident occasioned some delay, and the morning was consumed without our having made any considerable progress. At length, however, we got into a more open channel.

The river suddenly increased in breadth to thirty-five or forty-five yards, with a depth of from twelve to twenty feet of water. Its banks shelved perpendicularly down, and were almost on a level with the surface of the stream; and the flood mark was not more than two feet high on the reeds by which they were lined. We had hitherto pa.s.sed under the shade of the flooded gum, which still continued on the immediate banks of the river; but, the farther we advanced, the more did we find these trees in a state of decay, until at length they ceased, or were only rarely met with.

TERMINATION OF THE RIVER.

About 2 p.m. I brought up under a solitary tree, in consequence of heavy rain: this was upon the left bank. In the afternoon, however, we again pushed forward, and soon lost sight of every other object amidst reeds of great height. The channel of the river continued as broad and as deep as ever, but the flood mark did not show more than a foot above the banks, which were now almost on a level with the water; and the current was so sluggish as to be scarcely perceptible. These general appearances continued for about three miles, when our course was suddenly, and most unexpectedly, checked. The channel, which had promised so well, without any change in its breadth or depth, ceased altogether; and whilst we were yet lost in astonishment at so abrupt a termination of it, the boat grounded. It only remained for us to examine the banks, which we did with particular attention. Two creeks were then discovered, so small as scarcely to deserve the name, and which would, under ordinary circ.u.mstances, have been overlooked. The one branched off to the north--the other to the west. We were obliged to get out of the boat to push up the former, the leeches sticking in numbers to our legs. The creek continued for about thirty yards, when it was terminated; and, in order fully to satisfy myself of the fact, I walked round the head of it by pushing through the reeds. Night coming on, we returned to the tree at which we had stopped during the rain, and slept under it. The men cut away the reeds, or we should not have had room to move. At 2 a.m. it commenced raining, with a heavy storm of thunder and lightning; the boat was consequently hauled ash.o.r.e, and turned over to afford us a temporary shelter. The lightning was extremely vivid, and frequently played upon the ground, near the firelocks, for more than a quarter of a minute at a time.

It is singular, that Mr. Oxley should, under similar circ.u.mstances, have experienced an equally stormy night, and most probably within a few yards of the place on which I had posted myself. Notwithstanding that the elements were raging around me, as if to warn me of the danger of my situation, my mind turned solely on the singular failure of the river. I could not but encourage hopes that this second channel that remained to be explored would lead us into an open s.p.a.ce again; and as soon as the morning dawned we pursued our way to it. In pa.s.sing some dead trees upon the right bank, I stopped to ascend one, that, from an elevation, I might survey the marsh, but I found it impossible to trace the river through it.

The country to the westward was covered with reeds, apparently to the distance of seven miles; to the N.W. to a still greater distance; and to the north they bounded the horizon.

The whole expanse was level and unbroken, but here and there the reeds were higher and darker than at other places, as if they grew near constant moisture; but I could see no appearance of water in any body, or of high lands beyond the distant forest.

As soon as we arrived at the end of the main channel, we again got out of the boat, and in pushing up the smaller one, soon found ourselves under a dark arch of reeds. It did not, however, continue more than twenty yards when it ceased, and I walked round the head of it as I had done round that of the other. We then examined the s.p.a.ce between the creeks, where the bank receives the force of the current, which I did not doubt had formed them by the separation of its eddies. Observing water among the reeds, I pushed through them with infinite labour to a considerable distance. The soil proved to be a stiff clay; the reeds were closely embodied, and from ten to twelve feet high; the waters were in some places ankle deep, and in others scarcely covered the surface. They were flowing in different points, with greater speed than those of the river, which at once convinced me that they were not permanent, but must have lodged in the night during which so much rain had fallen. They ultimately appeared to flow to the northward, but I found it impossible to follow them, and it was not without difficulty that, after having wandered about at every point of the compa.s.s, I again reached the boat.

CAUSES OF THE FAILURE OF THE RIVER.

The care with which I had noted every change that took place in the Macquarie, from Wellington Valley downwards, enabled me, in some measure, to account for its present features. I was led to conclude that the waters of the river being so small in body, excepting in times of flood, and flowing for so many miles through a level country without receiving any tributary to support their first impulse, became too sluggish, long ere they reached the marshes, to cleave through so formidable a barrier; and consequently spread over the surrounding country--whether again to take up the character of a river, we had still to determine. Unless, however, a decline of country should favour its a.s.suming its original shape, it was evident that the Macquarie would not be found to exist beyond this marsh, of the nature and extent of which we were still ignorant. The loss of my barometer was at this time severely felt by me, since I could only guess at our probable height above the ocean; and I found that my only course was to endeavour to force my way to the northward, to ascertain, if I could, from the bottom of the marshes; then penetrate in a westerly direction beyond them, in order to commence my survey of the S.W.

interior. I was aware of Mr. Hume's perseverance, and determined, therefore, to wait the result of his report ere I again moved the camp, to which we returned late in the afternoon of the second day of our departure. We found it unsufferably hot and suffocating in the reeds, and were tormented by myriads of mosquitoes, but the waters were perfectly sweet to the taste, nor did the slightest smell, as of stagnation, proceed from them. I may add that the birds, whose sanctuary we had invaded, as the bittern and various tribes of the galinule, together with the frogs, made incessant noises around us, There were, however, but few water-fowl on the river; which was an additional proof to me that we were not near any very extensive lake.

MR. HUME'S REPORT.

Mr. Hume had returned before me to the camp, and had succeeded in finding a serpentine sheet of water, about twelve miles to the northward; which he did not doubt to be the channel of the river. He had pushed on after this success, in the hope of gaining a further knowledge of the country; but another still more extensive marsh checked him, and obliged him to retrace his steps. He was no less surprised at the account I gave of the termination of the river, than I was at its so speedily re-forming, and it was determined to lose no time in the further examination of so singular a region.

FALSE CHANNEL; PERPLEXITIES.

On the morning of the 28th therefore we broke up the camp, and proceeded to the northward, under Mr. Hume's guidance, moving over ground wholly subject to flood, and extensively covered with reeds; the great body of the marsh lying upon our left. After pa.s.sing the angle of a wood, upon our right, from which Mount Foster was distant about fourteen miles, we got upon a small plain, on which there was a new species of tortuous box. This plain was clear of reeds, and the soil upon it was very rich. Crossing in a westerly direction we arrived at the channel found by Mr. Hume, who must naturally have concluded that it was a continuation of the river. The boat was immediately prepared, and I went up it in order to ascertain the nature of its formation. For two miles it preserved a pretty general width of from twenty to thirty yards; but at that distance began to narrow, and at length it became quite shallow and covered with weeds. We were ultimately obliged to abandon the boat, and to walk along a native path.

The country to the westward was more open than I had expected. About a quarter of a mile from where we had left the boat, the channel separated into two branches; to which I perceived it owed its formation, coming, as they evidently did, direct from the heart of the marsh. The wood through which I had entered it on the first occasion bore south of me, to which one of the branches inclined; as the other did to the S.W. An almost imperceptible rise of ground was before me, which, by giving an impetus to the waters of the marsh, accounted to me for the formation of the main channel. It was too late, on my return to the camp, to prosecute any further examination of it downwards; but in the morning, Mr. Hume accompanied me in the boat, to ascertain to what point it led; and we found that at about a mile it began to diminish in breadth, until at length it was completely lost in a second expanse of reeds. We pa.s.sed a singular scaffolding erected by the natives, on the side of the channel, to take fish; and also found a weir at the termination of it for the like purpose so that it was evident the natives occasionally ventured into the marshes.

There was a small wood to our left which Mr. Hume endeavoured to gain, but he failed in the attempt. He did, however, reach a tree that was sufficiently high to give him a full view of the marsh, which appeared to extend in every direction, but more particularly to the north, for many miles. We were, however, at fault, and I really felt at a loss what step to take. I should have been led to believe from the extreme flatness of the country, that the Macquarie would never a.s.sume its natural shape, but from the direction of the marshes I could not but indulge a hope that it would meet the Castlereagh, and that their united waters might form a stream of some importance. Under this impression I determined on again sending Mr. Hume to the N.E. in order to ascertain the nature of the country in that direction.

EXCURSION TO THE NORTH-WEST.

The weather was excessively hot, and as my men were but slowly recovering, I was anxious while those who were in health continued active, to give the others a few days of rest. I proposed, therefore, to cross the river, and to make an excursion into the interior, during the probable time of Mr. Hume's absence; since if, as I imagined, the Macquarie had taken a permanent northerly course, I should not have an opportunity of examining the distant western country. Mr. Hume's experience rendered it unnecessary for me to give him other than general directions.

A PLAIN ON FIRE.

On the last day of the year we left the camp, each accompanied by two men.

I had the evening previously ordered the horses I intended taking with me across the channel, and at an early hour of the morning I followed them.

Getting on a plain, immediately after I had disengaged myself from the reeds on the opposite side of the river, which was full of holes and exceedingly treacherous for the animals, I pushed on for a part of the wood Mr. Hume had endeavoured to gain from the boat, with the intention of keeping near the marsh. On entering it, I found myself in a thick brush of eucalypti, casuarinae and minor trees; the soil under them being mixed with sand. I kept a N.N.W. course through it, and at the distance of three miles from its commencement, ascended a tree, to ascertain if I was near the marshes; when I found that I was fast receding from them. I concluded, therefore, that my conjecture as to their direction was right, and altered my course to N.W., a direction in which I had observed a dense smoke arising, which I supposed had been made by some natives near water.

At the termination of the brush I crossed a barren sandy plain, and from it saw the smoke ascending at a few miles' distance from me. Pa.s.sing through a wood, at the extremity of the plain, I found myself at the outskirts of an open s.p.a.ce of great extent, almost wholly enveloped in flames. The fire was running with incredible rapidity through the rhaG.o.dia shrubs with which it was covered. Pa.s.sing quickly over it, I continued my journey to the N.W. over barren plains of red sandy loam of even surface, and bushes of cypresses skirted by acacia pendula. It was not until after sunset that we struck upon a creek, in which the water was excellent; and we halted on its banks for the night, calculating our distance at twenty-nine miles from the camp. The creek was of considerable size, leading northerly. Several huts were observed by us, and from the heaps of muscle-sh.e.l.ls that were scattered about, there could be no doubt of its being much frequented by the natives. The gra.s.s being fairly burnt up, our animals found but little to eat, but they had a tolerable journey and did not attempt to wander in search of better food. I shot a snipe near the creek, much resembling the painted snipe of India; but I had not the means with me of preserving it.

A TRIBE OF NATIVES.

Continuing our journey on the following morning, we at first kept on the banks of the creek, and at about a quarter of a mile from where we had slept, came upon a numerous tribe of natives. A young girl sitting by the fire was the first to observe us as we were slowly approaching her. She was so excessively alarmed, that she had not the power to run away; but threw herself on the ground and screamed violently. We now observed a number of huts, out of which the natives issued, little dreaming of the spectacle they were to behold. But the moment they saw us, they started back; their huts were in a moment in flames, and each with a fire-brand ran to and fro with hideous yells, thrusting them into every bush they pa.s.sed. I walked my horse quietly towards an old man who stood more forward than the rest, as if he intended to devote himself for the preservation of his tribe. I had intended speaking to him, but on a nearer approach I remarked that he trembled so violently that it was impossible to expect that I could obtain any information from him, and as I had not time for explanations, I left him to form his own conjectures as to what we were, and continued to move towards a thick brush, into which they did not venture to follow us.

CONTINUE OUR JOURNEY.

After a ride of about eighteen miles, through a country of alternate plain and brush, we struck upon a second creek leading like the first to the northward. The water in it was very bitter and muddy, and it was much inferior in appearance to that at which we had slept. After stopping for half-an-hour upon its banks, to rest our animals, we again pushed forward.

We had not as yet risen any perceptible height above the level of the marshes, but had left the country subject to overflow for a considerable s.p.a.ce behind us. The brushes through which we had pa.s.sed were too sandy to retain water long, but the plains were of such an even surface, that they could not but continue wet for a considerable period after any fall of rain. They were covered with salsolaceous plants, without a blade of gra.s.s; and their soil was generally a red sandy loam. There were occasional patches that appeared moist, in which the calystemma was abundant, and these patches must, I should imagine, form quagmires in the wet season.

On leaving the last-mentioned creek, we found a gently rising country before us; and about three or four miles from it we crossed some stony ridges, covered with a new species of acacia so thickly as to prevent our obtaining any view from them. As the sun declined, we got into open forest ground; and travelled forwards in momentary expectation, from appearances, of coming in sight of water; but we were obliged to pull up at sunset on the outskirts of a larger plain without having our expectation realized.

The day had been extremely warm, and our animals were as thirsty as ourselves. Hope never forsakes the human breast; and thence it was that, after we had secured the horses, we began to wander round our lonely bivouac. It was almost dark, when one of my men came to inform me that he had found a small puddle of water, to which he had been led by a pigeon.

It was, indeed, small enough, probably the remains of a pa.s.sing shower; it was, however, sufficient for our necessities, and I thanked Providence for its bounty to us. We were now about sixty miles from the Macquarie, in a N.W. by W. direction, and the country had proved so extremely discouraging, that I intimated to my men my intention of retracing my steps, should I not discover any change in it before noon on the morrow.

A dense brush of acacia succeeded to the plain on which we had slept, which we entered, and shortly afterwards found ourselves in an open s.p.a.ce, of oblong shape, at the extremity of which there was a shallow lake. The brush completely encircled it, and a few huts were upon its banks. About 10 p.m. we got into an open forest track of better appearance than any over which we had recently travelled.

ISOLATED HILL.

There was a visible change in the country, and the soil, although red, was extremely rich and free from sand. A short time afterwards we rose to the summit of a round hill, from which we obtained an extensive view on most points of the compa.s.s. We had imperceptibly risen considerably above the general level of the interior.

VIEW FROM THE SUMMIT.
