Perplexity—Trait of honesty in the natives—Excursion on horseback across the Darling—Forced to return—Desolating effects of the drought—Retreat towards the colony—Connection between the Macquarie and the Darling—Return up the banks of the Macquarie—Starving condition of the natives.
On our return to the party, we found them surrounded by the natives, who were looking with an eye of wonder on the cattle and horses. We pointed out to them the direction in which we were going, and invited them to visit us; and nothing appeared to astonish them so much as the management of the team by a single man. We got back to our position early, and again fixed ourselves upon it.
It now only remained for us to consider what we should do under circumstances of certainly more than ordinary perplexity. We had nothing to hope for from travelling in a southerly direction, while to the E. and N.E., the state of the country was worse than that by which we had penetrated to the Darling. It was evident, that the large creeks joining the Castlereagh in that direction were dry, sincethe natives not only intimated this to us, but it was unquestionable that they themselves had deserted them, and had crowded to such places as still contained a supply of water. Even in retreating, we could not hope to retrace our steps. Experience had proved to us, that the dry state of the interior was as injurious to the movements of an expedition as a too wet season would have been. Taking everything, therefore, into consideration, I determined on leaving the party stationary, and on crossing the Darling to the N.W., and, if any encouraging feature presented itself, to return for the party, and persevere in an examination of the distant interior. Such, at least, appeared to me the most judicious plan: indeed, an attempt to have moved in any other direction would have been fruitless. And, as the result of this journey would be decisive, and would either fix or determine our advance or retreat, I was anxious for Mr. Hume's attendance.
The natives followed to the camp, and in the course of the afternoon, were joined by their women. The latter however, would not approach nearer than the top of a little hillock on which they sat. The men did not come round the tents, but stood in a row at a short distance. At sunset, they gained a little courage, and wandered about a little more; at length they went off to the Darling.
It was quite dark, when I heard a native call from the hill on which the women had been, and I desired Hopkinson to take his firelock and ascertain what the man wanted. He soon after returned, and brought a blanket,which he said the man had returned to him. The native was alone, and when he offered the blanket, kept his spear poised in his right hand; but, seeing that no violence was intended him, he lowered his weapon, and walked away.
I was extremely pleased at this trait of honesty, and determined to reward it. On inquiry, I found that the men had availed themselves of the day to wash their blankets and that one of them had been flung over a bush hanging over the bank of the river, and it was supposed that one of the natives must have pulled it down with him. In the morning, the tribe went away from their encampment before day-light as we judged from the cry of their dogs, than which nothing could be more melancholy; but about eight, the men made their appearance on the hill occupied by the women the evening previously, and seemed to be doubtful whether to approach nearer. I went out to them, and, with a downward motion of my hand, beckoned for them to come to me: they mistook the signal, but laid all their spears on the ground, and it was not until after the sign had been reversed that they stirred or moved towards me. I then got them in a row, and desired Hopkinson to single out the man who had given him the blanket. It was, however, with great difficulty that he recognised him, as the man stood firm and motionless. At length, after walking two or three times along the line, he stopped before one man, and put his hand on his shoulder, upon which the manner of the native testified as to the correctness of his guess.
The blanket being produced, I explained to the savage, with Mr. Hume's assistance, that I was highly pleased with him, and forthwith presented him with a tomahawk and a clasp-knife. The tribe were perfectly aware of the reason of my conduct, and all of them seemed highly delighted.
I was happy in having such an opportunity of showing the natives of the interior that I came among them with a determination to maintain justice in my communication with them, and to impress them, at the same time, with a sense of our love of it in them. That they appreciated my apparent lenity in not calling for the defaulter, I am sure, and I feel perfectly conscious that I should have failed in my duty had I acted otherwise than I did.
Although the natives had shown so good a disposition, as they were numerous, I thought it as well, since I was about to leave the camp, to show them that I had a power they little dreamt of about me. I therefore called for my gun and fired a ball into a tree. The effect of the report upon the natives, was truly ridiculous. Some stood and stared at me, others fell down, and others ran away; and it was with some difficulty we collected them again. At last, however, we did so, and, leaving them to pick out the ball, mounted our horses and struck away for the Darling. We crossed the river a little above where we struck it, and then proceeded N.W. into the interior.
It is impossible for me to describe the nature of the country over which we passed, for the first eight miles.We rode through brushes of polygonum, under rough-gum, without a blade of vegetation, the whole space being subject to inundation. We then got on small plains of firmer surface, and red soil, but these soon changed again for the former; and at 4 p.m. we found ourselves advanced about two miles on a plain that stretched away before us, and bounded the horizon. It was dismally brown; a few trees only served to mark the distance. Up one of the highest I sent Hopkinson, who reported that he could not see the end of it, and that all around looked blank and desolate. It is a singular fact, that during the whole day, we had not seen a drop of water or a blade of grass.
To have stopped where we were, would, therefore, have been impossible; to have advanced, would probably have been ruin. Had there been one favorable circumstance to have encouraged me with the hope of success, I would have proceeded. Had we picked up a stone as indicating our approach to high land, I would have gone on; or had there been a break in the level of the country, or even a change in the vegetation. But we had left all traces of the natives far behind us; and this seemed a desert they never entered—that not even a bird inhabited. I could not encourage a hope of success, and, therefore, gave up the point; not from want of means, but a conviction of the inutility of any further efforts. If there is any blame to be attached to the measure, it is I who am in fault, but none who had not like me traversed the interior at such a season, would believe the state of the country over whichI had wandered. During the short interval I had been out, I had seen rivers cease to flow before me, and sheets of water disappear; and had it not been for a merciful Providence, should, ere reaching the Darling, have been overwhelmed by misfortune.
I am giving no false picture of the reality. So long had the drought continued, that the vegetable kingdom was almost annihilated, and minor vegetation had disappeared. In the creeks, weeds had grown and withered, and grown again; and young saplings were now rising in their beds, nourished by the moisture that still remained; but the largest forest trees were drooping, and many were dead. The emus, with outstretched necks, gasping for breath, searched the channels of the rivers for water, in vain; and the native dog, so thin that it could hardly walk, seemed to implore some merciful hand to despatch it. How the natives subsisted it was difficult to say, but there was no doubt of the scarcity of food among them.
We arrived in camp at a late hour, and having nothing to detain us longer, prepared for our retreat in the morning. The natives had remained with the party during the greater part of the day, and had only left them a short time prior to our arrival.
When examining the creek on which we had been encamped for some days, Mr. Hume observed a small junction; and as we knew we were almost due N. of the marshes of the Macquarie, both of us were anxious toascertain whence it originated. To return to Mount Harris, by retracing our steps up the Castlereagh, would have entailed the severest distress upon us; we the rather preferred proceeding up this creek, and taking our chance for a supply of water. We therefore crossed Morrisset's chain of ponds, and encamped in the angle formed by the junction of the two creeks.
Before we left this position, we were visited by a party of natives, twelve in number, but not of the Darling tribe. They accompanied us a short way, and then struck off to the right. At about a mile and a half, we crossed Mr. Hume's track, leading westerly, which still remained observable. The creek was, no doubt, the hollow he stated that he crossed on that excursion, and its appearance certainly justified his opinion of it. Its bed was choked up with bulrushes or the polygonum, and its banks were level with the country on either side, or nearly so. We passed over extremely rich soil the whole day, on a S.W. and by W. course, though the timber upon it was dwarfish, and principally of the rough-gum kind.
On the 2nd of April, we stopped in order to make some repairs upon the dray; the wheels of which had failed us. Clayton put in four new spokes, and we heated the tyres over again, by which means we got it once more serviceable.
The soil in the creek was of the richest quality, and was found to produce a dwarf melon, having all the habits and character of the cucumber. The fruit was not larger than a pigeon's egg, but was extremely sweet. There were not,however, many ripe, although the runners were covered with flowers, and had an abundance of fruit upon them. In the morning, we sent the tinker on horseback up the creek, to ascertain how far the next water was from us, desiring him to keep the creek upon his right, and to follow his own track back again. He thought fit, however, considering himself a good bushman, to wander away to his left, and the consequence was, that he soon lost himself. It would appear that he doubled and passed through some thick brush at the back of the camp, and at length found himself at dark on the banks of a considerable creek. In wandering along it, he luckily struck upon the natives we had last seen, who, good-naturedly, led him to the track of the dray, which his horse would not afterwards desert, and the tinker sneaked into the tent about 3 o'clock in the morning, having failed in his errand, and made himself the butt of the whole party.
The day succeeding this adventure, we moved up the creek, which was, for the most part, even with the plain. The country continued the same as that we had passed over from the junction, being subject to flood, and having patches of bulrushes and reeds upon it. No change took place in the timber, but the line of acacia pendula, which forms the line of inundation, approached neater to us; nor was the mark of flood so high on the trunks of trees as below. We halted, with abominable water, but excellent food for the animals in the plains behind us. In continuing our journey, we found several changes take place in the appearance of the creek and its neighbourhood. The former diminished in size, and at length separated into two distinct channels, choked up, for the most part, with dead bulrushes, but having a few green reeds in patches along it. The flats on either side became slightly timbered, and blue gum was the prevailing tree. Crossing one of the channels, we observed every appearance of our near approach to the marshes, the flats being intersected by many little water-runs, such as we had noticed at the bottom of them. About noon we struck upon a body of reeds under the wood of eucalypti, below the second great morass, and keeping a little to our right to avoid them, fell shortly afterwards into our old track on the plain, upon which we continued to move, making the best of our way to the channel which had supplied our wants on our first return from the Darling. It was now, however, quite dry, and we were obliged to push on further, to shorten the journey of the morrow.
The result of our journey up the creek was particularly satisfactory, both to myself and Mr. Hume; since it cleared up every doubt that might have existed regarding the actual termination of the Macquarie, and enabled us to connect the flow of waters at so interesting and particular a point. It will be seen by a reference to the chart, that the waters of the marshes, after trickling through the reeds, form a small creek, which carries off the superfluous part of them into Morrisset's chain of ponds, which latter again falls into the Castlereagh, at about eight miles to the W.N.W. and all three join the Darling in a W. by N. direction, in lat. 30°52´ south and E. long. 147° 8´ at about 90 miles to the N.N.W. of Mount Harris, and about an equal distance to the E.S.E. of where we struck upon the last-mentioned river. Thus it is evident that the Darling had considerably neared the eastern ranges, although it was still more than 150 miles from their base. It was apparently coming from the N.E., and whether it has its sources in the mountains behind our distant settlements, or still farther to the northwards, is a question of curious speculation, although, as I have already stated, I am of opinion that none but tropical rains could supply the furious torrent that must sometimes rage in it.
It would be presumptuous to hazard any opinion as to the nature of the interior to the westward of that remarkable river. Its course is involved in equal mystery, and it is a matter of equal doubt whether it makes its way to the south coast, or ultimately exhausts itself in feeding a succession of swamps, or falls into a large reservoir in the centre of the island.
We reached Mount Harris on the 7th of the month, and moving leisurely up the banks of the Macquarie, gained Mr. Palmer's first station on the 14th, and Wellington Valley on the 21st, having been absent from that settlement four months and two weeks. The waters of the Macquarie had diminished so much, that its bed was dry for more than half a mile at a stretch, nor did we observe the least appearance of a current in it, until after we had ascended the ranges. The lower tribes were actually starving, and brought their children to us to implore something to eat. The men attempted to surprise the camp, but I believe they were urged from absolute necessity to procure subsistence for themselves, and that they intended robbery rather than personal violence.
We left the interior in a still more deplorable state than that in which we found it; but it is more than probable that under other circumstances, we should have found it impossible to traverse its distant plains, as it is certain that unless rain fell in less than three weeks, all communication with the Darling would have been cut off:
General remarks—Result of the expedition—Previous anticipations—Mr. Oxley's remarks—Character of the Rivers flowing westerly—Mr. Cunningham's remarks—Fall of the Macquarie—Mr. Oxley's erroneous conclusions respecting the character of the interior, naturally inferred from the state in which he found the country—The marsh of the Macquarie merely a marsh of the ordinary character—Captain King's observations—Course of the Darling—Character of the low interior plain—The convict Barber's report of rivers traversing the interior—Surveyor-General Mitchell's Report of his recent expedition.
Whether the discoveries that have been made during this expedition, will ultimately prove of advantage to the colony of New South Wales, is a question that time alone can answer. We have in the meanwhile to regret that no beneficial consequences will immediately follow them. The further knowledge that has been gained of the interior is but as a gleam of sunshine over an extensive landscape. A stronger light has fallen upon the nearer ground, but the distant horizon is still enveloped in clouds. The veil has only as it were been withdrawn from the marshes of the Macquarie to be spread over the channel of the Darling. Unsatisfactory, however, as the discoveries may as yet be considered in a commercial point of view, the objects for which the expedition had been fitted out were happily attained. The marsh it had been directed to examine, was traversed on every side, and the rivers it had been ordered to trace, were followed down to their terminations to a distance far beyond where they had ceased to exist as living streams. To many who may cast their eyes over the accompanying chart, the extent of newly discovered country may appear trifling; but when they are told, that there is not a mile of that ground that was not traversed over and over again, either by Mr. Hume or by myself, that we wandered over upwards of 600 miles more than the main body of the expedition, on different occasions, in our constant and anxious search for water, and that we seldom dismounted from our horses, until long after sunset, they will acknowledge the difficulties with which we had to contend, and will make a generous allowance for them; for, however unsuccessful in some respects the expedition may have been, it accomplished as much, it is to be hoped, as under such trying circumstances could have been accomplished. It now only remains for me to sum up the result of my own observations, and to point out to the reader, how far the actual state of the interior, has been found to correspond with the opinions that were entertained of it.
I have already stated, in the introduction to this work, that the general impression on the minds of those best qualified to judge was, that the western streams discharged themselvesinto a central shoal sea. Mr. Oxley thus expresses himself on the subject:—
“July 3rd. Towards morning the storm abated, and at day-light, we proceeded on our voyage. The main bed of the river was much contracted, but very deep; the waters spreading to the depth of a foot or eighteen inches over the banks, but all running on the same point of bearing. We met with considerable interruptions from fallen timber, which in places nearly choked up the channel. After going about twenty miles, we lost the land and trees; the channel of the river, which lay through reeds, and was from one to three feet deep, ran northerly.—This continued for three or four miles farther, when, although there had been no previous change in the breadth, depth, or rapidity of the stream for several miles, and I was sanguine in my expectations of soon entering the long-sought-for Australian sea, it all at once eluded our farther pursuit, by spreading on every point from N.W. to N.E. among the ocean of reeds which surrounded us, still running with the same rapidity as before. There was no channel whatever among those reeds, and the depth varied from three to five feet. This astonishing change (for I cannot call it a termination of the river) of course left me no alternative but to endeavour to return to some spot on which we could effect a landing before dark. I estimated, that during the day, we had gone about twenty-four miles, on nearly the same point of bearing as yesterday. To assert, positively, that we were on the margin of the lake, or sea, into which this great bodyof water is discharged, might reasonably be deemed a conclusion, which has nothing but conjecture for its basis. But if an opinion may be permitted to be hazarded from actual appearances, mine is decidedly in favour of our being in the immediate vicinity of an inland sea, or lake, most probably a shoal one, and gradually filling up by numerous depositions from the high lands, left by the waters which flow into it. It is most singular, that the high lands on this continent seem to be confined to the sea-coast, and not to extend to any distance from it.”
In a work published at Sydney, containing an account of Mr. Allan Cunningham's journey towards Moreton Bay, in 1828, the following remarks occur, from which it is evident Mr. Cunningham entertained Mr. Oxley's views of the character and nature of the Western interior. Towards the conclusion of the narrative, the author thus observes:—
“Of the probable character of the distant unexplored interior, into which it has been ascertainedallthe rivers falling westerly from the dividing ranges flow, some inference may be drawn from the following data.
“Viewing, between the parallels of 34° and 27°, a vast area of depressed interior, subjected in seasons of prolonged rains to partial inundation, by a dispersion of the several waters that flow upon it from the eastern mountains whence they originate; and bearing in mind at the same time, that the declension of the country within the above parallels, as most decidedly shown by the dip of its several rivers, is uniformlyto the N.N.W. and N.W., it would appear very conclusive, that either a portion of our distant interior is occupied by a lake of considerable magnitude, or that the confluence of those large streams, the Macquarie, Castlereagh, Gwydir, and the Dumaresq, with the many minor interfluent waters, which doubtless takes place upon those low levels, forms one or more noble rivers, which may flow across the continent by an almost imperceptible declivity of country to the north of north-west coasts, on certain parts of which, recent surveys have discovered to us extensive openings, by which the largest accumulations of waters might escape to the sea.”
It is the characteristic of the streams falling westerly from the eastern, or coast ranges, to maintain a breadth of channel and a rapidity of current more immediately near their sources, that ill accords with their diminished size, and the sluggish flow of their waters in the more depressed interior. In truth, neither the Macquarie nor the Castlereagh can strictly be considered as permanent rivers. The last particularly is nothing more than a mountain torrent. The Macquarie, although it at length ceased to run, kept up the appearance of a river to the very marshes; but the bed of the Castlereagh might have been crossed in many places without being noticed, nor did its channel contain so much water as was to be found on the neighbouring plains.
There are two circumstances upon which the magnitude, and velocity of a river, more immediately depend. The first is the abundance of its sources, the other the dip of itsbed. If a stream has constant fountains at its head, and numerous tributaries joining it in its course, and flows withal through a country of gradual descent, such a stream will never fail; but if the supplies do not exceed the evaporation and absorption, to which every river is subject, if a river dependant on its head alone, falls rapidly into a level country, without receiving a single addition to its waters to assist the first impulse acquired in their descent, it must necessarily cease to flow at one point or other. Such is the case with the Lachlan, the Macquarie, the Castlereagh, and the Darling. Whence the latter originates, still remains to be ascertained; but most undoubtedly its sources have been influenced by the same drought that has exhausted the fountains of the three first mentioned streams.
In supporting his opinion of the probable discharge of the interior waters of Australia upon its north-west coast, Mr. Cunningham thus remarks in the publication from which I have already made an extract.
“To those remarkable parts of the north-west coast above referred to in the parallel of 16° south, the Macquarie river, which rises in lat. 33°, and under the meridian of 150° east, would have a course of 2045 statute miles throughout, while the elevation of its source, being 3500 feet above the level of the sea as shown by the barometer, would give its waters an average descent of twenty inches to the mile, supposing the bed of the river to be an inclined plane.
“The Gwydir originating in elevated land, lying in 31° south, and long. 151° east, at a mean height of 3000 feet,would have to flow 2020 miles, its elevated sources giving to each a mean fall of seventeen inches.
“Dumaresq's river falling 2970 feet from granite mountains, in 28 1/4° under the meridian of 152°, would have to pursue its course for 2969 miles, its average fall being eighteen inches to a mile.”
As I have never been upon the banks either of the Gwydir or the Dumaresq, I cannot speak of those two rivers; but in estimating the sources of the Macquarie at 3500 feet above the level of the sea, Mr. Cunningham has lost sight of, or overlooked the fact, that the fall of its bed in the first two hundred miles, is more than 2800 feet, since the cataract, which is midway between Wellington Valley and the marshes, was ascertained by barometrical admeasurement, to be 680 feet only above the ocean. The country, therefore, through which the Macquarie would have to flow during the remainder of its course of 1700 miles, in order to gain the N.W. coast, would not be a gradually inclined plain, but for the most part a dead level, and the fact of its failure is a sufficient proof in itself how short the course of a river so circumstanced must necessarily be.
Having conversed frequently with Mr. Oxley on the subject of his expeditions, I went into the interior prepossessed in favour of his opinions, nor do I think he could have drawn any other conclusion than that which he did, from his experience of the terminations of the rivers whose courses he explored. Had Mr. Oxley advanced forty, or even thirty miles, farther than he did, to the westward ofMount Harris; nay, had he proceeded eight miles in the above direction beyond the actual spot from which he turned back, he would have formed other and very different opinions of the probable character of the distant interior. But I am aware that Mr. Oxley performed all that enterprise, and perseverance, and talent could have performed, and that it would have been impracticable in him to have attempted to force its marshes in the state in which he found them. It was from his want of knowledge of their nature and extent, that he inferred the swampy and inhospitable character of the more remote country, a state in which subsequent investigation has found it not to be. The marsh of the Macquarie is nothing more than an ordinary marsh or swamp in another country. However large a space it covers, it is no more than a concavity or basin for the reception of the waters of the river itself, nor has it any influence whatever on the country to the westward of it, in respect to inundation; the general features of the latter being a regular alternation of plain and brush. These facts are in themselves sufficient to give a fresh interest to the interior of the Australian continent, and to increase its importance.
With respect to that part of its coast at which the rivers falling from the eastern mountains, discharge themselves, it is a question of very great doubt. It seems that Capt. King, in consequence of some peculiarities in the currents at its N.W. angle, supports Mr. Cunningham's opinion as to their probable discharge in that quarter. But I fear the internal structure of the continent is so low, as to precludethe hopes of any river reaching from one extremity of it to the other. A variety of local circumstances, as the contraction of a channel, a shoal sea, or numerous islands, influence currents generally, but more especially round so extensive a continent as that of which we are treating; nor does it strike me that any observations made by Capt. King during his survey, can be held to bear any connection with the eastern ranges, or their western waters. It may, however, be said, that as the course of the Darling is still involved in uncertainty, the question remains undecided; but it appears to me, the discovery of that river has set aside every conjecture (founded on previous observation) respecting the main features of the interior lying to the westward of the Blue Mountains. Both Mr. Oxley and Mr. Cunningham drew their conclusions from the appearances of the country they severally explored. The ground on which those theories were built, has been travelled over, and has not been found to realize them, but subsequent investigation has discovered to us a river, the dip of whose bed is to the S.W. We have every reason to believe that the sources of this river must be far to the northward of the most distant northerly point to which any survey has been made, as we are certain that it is far beyond the stretch of vision from the loftiest and most westerly of the barrier ranges; from which circumstance, it is evident that whatever disposition the streams descending from those ranges to the westward may show to hold a N.W. course more immediately at the base, the whole of the interior streams, from the Macquarieto the Dumaresq, are tributaries to the principal channel which conveys their united waters at right angles, if not still more opposite to the direction they were supposed to take, as far as is yet known.
The Darling River must be considered as the boundary line to all inland discoveries from the eastward. Any judgment or opinion of the interior to the westward of that stream, would be extremely premature and uncertain. There is not a single feature over it to guide or to strengthen either the one or the other.
My impression, when travelling the country to the west and N.W. of the marshes of the Macquarie, was, that I was traversing a country of comparatively recent formation. The sandy nature of its soil, the great want of vegetable decay, the salsolaceous character of its plants, the appearance of its isolated hills and flooded tracts, and its trifling elevations above the sea, severally contributed to strengthen these impressions on my mind. My knowledge of the interior is, however, too limited to justify me in any conclusion with regard to the central parts of Australia. An ample field is open to enterprise and to ambition, and it is to be hoped that some more decisive measures will be carried into effect, both for the sake of the colony and of geography, to fill up the blank upon the face of the chart of Australia, and remove from us the reproach of indifference and inaction.
Since the above pages were written, an expedition was undertaken by Major Mitchell, the Surveyor-General, toascertain the truth of a report brought in by a runaway convict of the name of Barber, or Clarke, who had been at large for five years, at different times, among the natives to the northward of Port Macquarie. This man stated that a large river, originating in the high lands near Liverpool Plains, and the mountains to the north of them, pursued a N.W. course to the sea. His story ran thus: Having learnt from the natives the existence of this river, he determined to follow it down, in hopes that he might ultimately be enabled to make his escape from the colony. He accordingly started from Liverpool Plains, and kept on a river called the Gnamoi, for some time, which took him N.W. After a few days' journey, he left this river, traversed the country northwards, and crossed some lofty ranges. Descending to the N.E. he came to another large river, the Keindur, which again took him N.W. He travelled 400 miles down it, when he observed a large stream joining it upon its left bank, which he supposed to be the Gnamoi. The river he was upon was broad and navigable. It flowed through a level country with a dead current and muddy water, and spread into frequent lakes. He found that it ultimately discharged itself into the sea, but was uncertain at what distance from its sources. He was positive he never travelled to thesouthward of west. He ascended a hill near the sea, and observed an island in the distance, from which, the natives informed him, a race of light-coloured men came in large canoes for a scented wood; but having failed in the immediate object of his journey, he was eventually obliged to return.
The following official report of Major Mitchell will sufficiently point out the incorrectness of the preceding statement. It is most probable that Barber merely told that which he had heard from the natives, and that having a more than ordinary share of cunning, he made up a story upon their vague and uncertain accounts, in hopes that it would benefit him, as in truth it did.
Bullabalakit, on the River Nammoy,in lat. 30° 38´ 21´´ S.,long. 149° 30´ 20´´ E.23rd December, 1831.
SIR,
I have the honour to state, for the information of His Excellency the Governor, the progress I have made in exploring the course of the interior waters to the northward of the Colony, with reference to the letter which I had the honour to address to Col. Lindesay, on this subject, on the 19th ult.
On crossing Liverpool Range my object was to proceed northward, so as to avoid the plains and head the streams which water them, and avoiding also the mountain ranges on the east.
I arrived accordingly, by a tolerably straight and level line, at Walamoul, on Peel's River; this place (a cattle station of Mr. Brown) being nearly due north from the common pass across Liverpool Range, and about a mile-and-a-half above the spot where Mr. Oxley crossed this river.
I found the general course of the Peel below Walamoul to be nearly west; and after tracing this river downwards twenty-two miles (in direct distance), I crossed it at an excellent ford, named Wallamburra. I then traversed the extensive plain of Mulluba; and leaving that of Coonil on the right, extending far to the north-east, we passed through a favourable interval of what I considered Hardwicke's Range, the general direction of this range being two points west of north.
On passing through this gorge, which, from the name of a hill on the south side, may be named Ydire, I crossed a very extensive tract of flat country, on which the wood consisted of iron-bark and acacia pendula; this tract being part of a valley evidently declining to the north-west, which is bounded on the south by the Liverpool Range, and on the south-west by the extremities from the same. On the west, at a distance of twenty-two miles from Hardwicke's Range, there stands a remarkable isolated hill named Bounalla; and towards the lowest part of the country, and in the direction in which all the waters tend, there is a rocky peak named Tangulda. On the north, a low range (named Wowa), branching westerly from Hardwicke's Range, bounds on that side this extensive basin, which includes Liverpool Plains. Peel's River is the principal stream, and receives, in its course, all the waters of theseplains below the junction of Connadilly,—which I take to be York's River, of Oxley.
The stream is well known to the natives by the name Nammoy; and six miles below Tangulda, the low extremities from the surrounding ranges close on the river, and separate this extensive vale from the unexplored country which extends beyond to an horizon which is unbroken between W.N.W. and N.N.W.
The impracticable appearance of the mountains to the northward, induced me to proceed thus far to the west; and on examining the country thirty miles N.E. by N. from Tangulda, I ascended a lofty range extending westward from the coast chain, and on which the perpendicular sides of masses of trachyte (a volcanic rock) were opposed to my further progress even with horses: it was therefore evident that the river supposed to rise about the latitude of 28° would not be accessible, or at least available to the Colony, in that direction, and that in the event of the discovery of a river beyond that range flowing to the northern or north-western shores, it would become of importance to ascertain whether it was joined by the Nammoy, the head of this river being so accessible that I have brought my heavily laden drays to where it is navigable for boats, my present encampment being on its banks six miles below Tangulda. From this station I can perceive the western termination of the Trachytic range, and I am now about to explore the country between it and the Nammoy, and the further course of this river; and in the event of its continuance in a favourabledirection, I shall fix my depot on its right bank, whence I now write, and descend the stream in the portable boats.

Peel's River, 29th February, 1832.
SIR,
I have the honour to inform you, for the information of His Excellency the Governor, that I have reached the left bank of this River with my whole party on my return from the northern interior, having explored the course of the river referred to in my letter of 22nd December last, and others within the 29th parallel of latitude.
There was so much fallen timber in the Nammoy, and its waters were so low, that the portable boats could not be used on that river with advantage, and I proceeded by land in a north-west direction, until convinced by its course turning more to the westward that this river joined the river Darling. I therefore quitted its banks with the intention of exploring the country further northward, by moving round the western extremities of the mountains mentioned in my former letter, and which I have since distinguishedin my map by the name of the Lindesay Range. These mountains terminate abruptly on the west, and I entered a fine open country at their base, from whence plains (or rather open ground of gentle undulation) extended westward as far as could be seen. On turning these mountains I directed my course northward, and to the eastward of north, into the country beyond them, in search of the riverKindur; and I reached a river flowing westward, the bed of which was deep, broad, and permanent, but in which there was not then much water.
The marks of inundation on trees, and on the adjoining high ground, proved that its floods rose to an extraordinary height; and from the latitude, and also from the general direction of its course, I considered this to be the river which Mr. Cunningham named the Gwydir, on crossing it sixty miles higher, on his route to Moreton Bay. I descended this river, and explored the country on its left bank for about eighty miles to the westward, when I found that its general course was somewhat to the southward of west. This river received no addition from the mountains over that part of its left bank traversed by me; and the heat being intense, the stream was at length so reduced that I could step across it. The banks had become low, and the bed much contracted, being no longer gravelly, but muddy. I therefore crossed this river and travelled northward, on a meridian line, until, in the latitude of 29° 2´, I came upon the largest river I had yet seen. The banks were earthy and broken, the soil being loose, and the water of a whitemuddy colour. Trees, washed out by the roots from the soft soil, filled the bed of this river in many places. There was abundance of cod-fish of a small size, as well as of the two other kinds of fish which we had caught in the Peel, the Nammoy, and the Gwydir. The name of this river, as well as we could make it out from the natives, was Karaula. Having made fast one tree to top of another tall tree, I obtained a view of the horizon, which appeared perfectly level, and I was in hopes that we had at length found a river which would flow to the northward and avoid the Darling. I accordingly ordered the boat to be put together, and sent Mr. White with a party some miles down to clear away any trees in the way. Mr. White came upon a rocky fall, and found besides the channel so much obstructed by trees, and the course so tortuous, that I determined to ascertain before embarking upon it, whether the general course was in the desired direction. Leaving Mr. White with half the party, I accordingly traced the Karaula downwards, and found that its course changed to south, a few miles below where I had made it, and that it was joined by the Gwydir only eight miles below where I had crossed that river. Immediately below the junction of the Gwydir (which is in latitude 29° 30´ 27´´, longitude 148° 13´ 20´´) the course of the river continues southward of west, directly towards where Captain Sturt discovered the River Darling; and I could no longer doubt that this was the same river. I therefore returned to the party, determined to explore the country further northward.
The results of my progress thus far were sufficient, I considered, to prove that the division of the waters falling towards the northern and southern shores of Australia is not, as has been supposed, in the direction of the Liverpool and Warrabangle range, but extends between Cape Byron on the eastern shore, towards Dick Hartog's Island on the west; the greater elongation of this country being between these points, and intermediate between the lines of its northern and southern coasts. The basin of the streams I have been upon must be bounded on the north by this dividing ground or water-shed, and although no rise was perceptible in the northern horizon, the river was traversed by several rocky dykes, over which it fell southward; their direction being oblique to the course, and nearly parallel to this division of the waters. I beg leave to state, that I should not feel certain on this point without having seen more, were it not evident from Mr. Cunningham's observations, made on crossing this division on his way to Moreton Bay. Mr. Cunningham, on crossing the head of this river, nearly in the same latitude, but much nearer its sources, found the height of its bed above the sea to be 840 feet; at about forty-five miles further northward the ground rose to upwards of 1700 feet, but immediately beyond, he reached a river flowing north-west, the height of which was only 1400 feet above the sea. He had thus crossed this dividing higher ground, between the parallels of 29° and 28°. It appears, therefore, that all the interior rivers we know of to the northward of the Morumbidgee, belong to the basin of the Karaula; this stream flowing southward, and hence the disappearance of the Macquarie and other lower rivers may be understood, for all along the banks of the Karaula, the Gwydir, and the Nammoy, the country, though not swampy, bears marks of frequent inundation; thus the floods occasioned by these rivers united, cover the low country, and receive the Macquarie so that no channel marks its further course.
That a basin may be found to the northward receiving the waters of the northern part of the coast range in a similar manner is extremely probable, and that they form a better river, because the angle is more acute between the high ground, which must bound it on the N.E. and the watershed on the south. I therefore prepared to cross the Karaula, in hopes of seeing the head at least of such a river, and to explore the country two degrees further northward, but moving in a N.W. direction. My tent was struck, and I had just launched my portable boat for the purpose of crossing the river, when Mr. Surveyor Finch, whom I had instructed to bring up a supply of flour, arrived with the distressing intelligence, that two of his men had been killed by the natives, who had taken the flour, and were in possession of everything he had brought—all the cattle, including his horse, being also dispersed or lost. I therefore determined not to extend my excursion further, as the party were already on reduced rations, and on the 8th instant I retired from the Karaula, returning by the marked line, which being cut through thick scrubs invarious places, is now open, forming a tolerably direct line of communication in a N.W. direction from Sydney, to a river, beyond which the survey may be extended whenever His Excellency the Governor thinks fit.
The natives had never troubled my party on our advance; indeed I only saw them when I came upon them by surprise, and then they always ran off. Their first visit was received at my camp on the Karaula, during my absence down that river, when they were very friendly, but much disposed to steal. Various tribes followed us on coming back, but never with any show of hostility, although moving in tribes of a hundred or more parallel to our marked line, or in our rear; it was necessary to be ever on our guard, and to encamp in strong positions only, arranging the drays for defence during the night: three men were always under arms, and I have much pleasure in stating, that throughout the whole excursion, and under circumstances of hardship and privation, the conduct of the men was very good. I took an armed party to the scene of pillage, and buried the bodies of the two men, who appeared to have been treacherously murdered while asleep by the blacks during the absence of Mr. Finch: no natives were to be found when I visited the spot, although it appeared from columns of smoke on hills which overlooked if, that they were watching our movements.
The party has now arrived within a day's journey of Brown's station, and I have instructed Assistant-Surveyor White (from whom I have received great assistance duringthe whole journey) to conduct it homewards, being desirous to proceed without delay to Sydney, and to receive the instructions of His Excellency the Governor.
I have the honour to be, Sir,Your most obedient Servant,T. L. MITCHELL,Surveyor-General.
