September 21.—With a severe frost, the morning and day were finer than usual, though the weather was very unsettled. We accomplished seven miles on a south-east by east course, through a very heavily wooded country; the timber generally of the best description, and the soil, with some partial exceptions, was equally good and rich. It was, however, so thickly covered with ferns and bushes among the trees, with vines running from them, that in many places we found it difficult to pass. Our course was accidentally such as to avoid all the deep valleys but two, the descents of which were extremely difficult. In them strong streams of water ran to the north-east, no doubt joining the main river. From the hill over one of the streams near which we halted the coast line of hills was plainly seen; and we appeared to have but a rugged journey before us. Our horses too were so extremely weak and crippled, that the short distance we are enabled to travel is accomplished with pain and difficulty. We were forced to leave one of them about a mile and a half from our resting-place, as he was utterly unable even to walk without his load. which was distributed among the others. Some natives' fires were seen about two miles to the north-east of us in the same valley.

September 22.—A dark tempestuous morning. Sent back for the horse we left yesterday afternoon: he was somewhat recovered, and may perhaps live to reach the coast, the point whither our hopes have long pointed, and where I trust the horses will experience some relaxation from their present incessant but necessary labour. We had no choice in the route we pursued this day, taking that which appeared most practicable for men and horses: it was a continued ascending and descending of the most frightful precipices, so covered with trees and shrubs and creeping vines, that we frequently were obliged to cut our way through: at the bottom of one of these, we left the sick horse in a dying state. To add to our perplexities, it rained incessantly, and was so thick and dark, that towards evening it was with difficulty we could see sufficient of our way to avoid being dashed to pieces. About two hours before sunset, after a descent of upwards of five thousand feet, we found ourselves at the bottom of the glen, through which ran a small stream; but a passage down it was impossible, as it fell over rocky precipices to a still greater depth. The opposite side was a mountain equally steep with the one we had just descended. The horses were also so weak that it was impossible they could take their loads up it, and there was no possibility of remaining on the spot, since there was neither grass nor room even to lie down. All the heavy baggage was therefore obliged to be left behind, and by unremitted exertion we were enabled to gain a small spot of ground, formed by the mountains retiring from the immediate descent to the gulf below. It was, however, near eight o'clock before this was accomplished; and we were after all obliged to leave two of the horses below, as all our attempts to move them were fruitless, even when unladen; a circumstance which we lamented the more, as they were on a spot that did not afford a blade of grass. The rain ceasing, was succeeded about nine o'clock by one of the severest storms of wind I ever remember to have witnessed; and for the first time perhaps during the journey, we were alarmed for our personal safety. The howling of the wind down the sides of the mountain, the violent agitation of the trees, and the crash of falling branches, made us every instant fear that we should be buried under the ruins of some of the stupendous trees which surrounded us.

September 23.—Towards midnight the storm abated, and allowed us to pass the remainder of the night in comparative comfort. The morning broke fair, and as the state of the horses would not permit us to attempt ascending the mountain with the baggage to-day, I contented myself with dispatching them for the provisions left last night at the bottom of the precipice, and to get up if possible the two remaining horses, whilst Mr. Evans and myself should explore the range, and endeavour to find out a somewhat more practicable route. We proceeded to ascend the mountain, the summit of which was near two miles distant, and in many places extremely difficult and abrupt. We however remarked on our road seven native huts, which increased our hopes that these mountains would lead by a comparatively easy descent to the coast line of country. Bilboa's ecstasy at the first sight of the South Sea could not have been greater than ours, when on gaining the summit of this mountain, we beheld Old Ocean at our feet: it inspired as with new life: every difficulty vanished, and in imagination we were already at home. We proceeded sufficiently far to discover, that although our descent would be both difficult and dangerous, it would not be impracticable. The country between us and the sea was broken into considerable forest hills and pleasing valleys, down the principal of which we could distinguish a small stream taking its course to the sea. To the north and south the country was mountainous and broken beyond any thing we had seen. Indeed, some idea of those barrier mountains may be formed from the circumstance, that although we could distinctly see the ocean, and the waving of the coast line, (which within the distance of ten or twelve miles from the beach appeared low), yet we were still nearly fifty miles from it. I estimated the height of this mountain at between six and seven thousand feet; and yet the country north and south appeared equally elevated. Numerous smokes arising from natives' fires announced a country well inhabited, and gave the whole picture a cheerful aspect, which reflected itself on our minds; and we returned to the tents with lighter hearts and better prospects. In removing the baggage left at the bottom of the hill a short quarter of a mile, a most distressing accident occurred. A mare, one of the strongest we had, in bringing up a very light load, not a quarter of her usual burden, and when within one hundred yards of the tent, literally burst with the violent exertion which the ascent required. In this shocking state, with her entrails on the ground, she arrived at the tent, when, to put an end to her agonies, she was shot. This was a serious loss to us, in addition to that which we suffered on the day before: and three more horses were so worn, that I scarcely expected to force them along even unladen. It must not be supposed that we attempted to climb these hills in a direct line; it would have been scarcely possible for a man to do it: we wound round them in every practicable direction; and the loose rich soil of which they were generally composed, together with the thickness of the timber, by preventing our falling, favoured our progress. In the course of the afternoon I tried the angle of elevation and depression on various parts, and found it to be from 30 to 35 and even 40 degrees. By the same means we found that the mountain which we had descended yesterday evening exceeded four thousand seven hundred feet in height on those angles. The mountain we shall have to ascend to-morrow is very considerably higher; but, with one or two exceptions, the ascents are not so abrupt. After the provisions were brought up, all hands were sent to cut a road for the horses through the brushes which surrounded the bottoms of the steepest ascents, and without which it would have been impossible for them to pass laden; the vines which crossed each other in various directions forming an almost impenetrable barrier. It may seem superfluous to speak of soil and timber among such mountains as these; yet I will say that except where the rocks presented a perpendicular face, and along the highest ridges, the soil was light and good. The timber consisted of blue gum and stringy bark, and forest oak [Note: Casuarina torulosa.] of the largest dimensions: the gorges of the valleys were covered with loose small stones, and in those gorges all the trees which are usually found in places of a similar description in the district of the Five Islands (with the exception of the red cedar), were to be met with. The stones and rocks were mixed with a considerable portion of quartz, and were generally in loose detached masses of various sizes. The mountain from whence we first saw the ocean was named Sea View Mount, and I should think might be distinctly seen by ships at some distance from the coast.

September 24.—At eight o'clock the horses began to ascend the mountain, and it was twelve before we reached the summit, a distance of exactly two miles. How the horses descended I scarcely know; and the bare recollection of the imminent dangers which they escaped, makes me tremble. At one period of the descent, I would willingly have compromised for a loss of one third of them, to ensure the safety Of the remainder. It is to the exertions and steadiness of the men, under Providence, that their safety must be ascribed. The thick tufts of grass and the loose soil also gave them a surer footing, of which the men skillfully availed themselves. The length of the descent was two measured miles and three quarters, and upon first, an angle of depression of 40 degrees for one thousand two hundred and fifty-four feet: we then slightly ascended 4 or 6 degrees for four thousand six hundred and twenty, and from thence the descent, in a continued straight line, to the run of water at the base, was on the various angles of 28, 32, 35, 40, and 46 degrees, eight thousand five hundred and eighty feet; from whence I deduce the perpendicular height to be nearly six thousand feet, which is certainly underrated. The descent terminated in a very narrow steep valley, down which we proceeded for near three quarters of a mile, when the small stream before mentioned joined a very considerable one seen yesterday from Sea View Mount; and the valley opening, we halted on the banks of the river on a spot which afforded us plenty of excellent grass, and was in other respects favourable for that rest which the horses required before they could resume their journey. One of the horses when about a third down the mountain was quite incapable of proceeding, we therefore were obliged to leave him for the night, with the loads of two other horses. It was past four o'clock before we arrived at our halting-place, having been exactly three hours and a half in descending.

September 25.—Despatched the men to bring down the horse and the baggage left on the mountain yesterday. They returned in the afternoon with both, but the horse was scarcely able to stand. In the course of the day examined the valley a few miles, when we found that it opened considerably four or five miles down; the hills previously thereto being very steep, but covered with grass, and abounding with kangaroos. It was therefore determined to move farther down the river to-morrow, instead of remaining here two days as originally proposed. In the present reduced state of the horses, we were obliged to make short stages with frequent halts, in hopes of sufficiently recruiting their strength so as to proceed with greater expedition along the coast.

September 26.—We proceeded between four and five miles down the river, which was named Hastings River, in honour of the Governor General of India; the vale gradually opening to a greater width between steep and lofty hills, the soil on which was very stony, but rich, and covered with fine grass two or three feet high. At the place where we stopped, small rich flats began to extend on either side, and confirmed our hopes that we should find a more regular country as we approached the sea. The route which we had travelled lay over steep and sharp points of mountains ending on the river, but did not offer any great obstruction. Yet we were obliged to leave the horse which had failed the day before, half-way, as he dropped through utter weakness, though unladen. These valleys and hills are astonishingly rich in timber of various kinds, many new, and their botanic supplies were inexhaustible. Indeed our cargo now principally consists of plants.

September 27.—The morning fine and clear. Sent back for the horse left yesterday, which with some difficulty was brought to the tent. Observed our latitude to be 31. 23. 10. S., longitude by estimation 152. 8. E., variation 8. 22. E. We this day cleaned all the arms, and put our military appointments in order to guard against any hostile attempts that might be made by the natives, who are reported to be in this quarter numerous and treacherous.

September 28.—As we proceeded down the river, the vale still continued to open on either hand, the hills receding from each bank of the stream from two to three miles. The land on the more elevated spots, and irregular low hills, was strong but of good soil, covered with grass: the flats which occurred alternately on both sides of the river were very rich, the grass long and coarse; the timber, blue gum and apple tree. As the points of the higher hills sometimes closed on the river, we found it convenient to cross it, which in the course of the day we did no less than three times. In the hollows of the higher hills were thick brushes of the same description as those at the Five Islands. About six miles and a half down the river it was joined by a considerable stream from the northward, running through a fine and spacious valley. The accession of this water materially altered the appearance of the river, as it began to form long and wide reaches, with alternate rapids over a shingly bottom. The northern stream was named Forbes's River, in honour of the Marquis of Hastings' nephew. Although our proximity to the sea seemed to preclude the probability of Hastings River being joined by any other considerable waters; yet its present size made us a little anxious to find that it had a serviceable discharge into the ocean. The ground over which we travelled being very favourable to the weak state of the horses, we accomplished between eight and nine miles. Kangaroos abounded; four were this day killed. Marks of flood were observed to the height of sixteen feet, but the river appeared now to be in its lowest state, and the sides of the barren mountains showed that there had been no rain of any consequence for a considerable time.

September 29.—The country we passed through is what is generally known in New South Wales as open forest land, with occasionally small flats on the river: steep hills sometimes ended on the river, and north and south of us were detached ranges of a similar description. The whole face of the country was abundantly covered with good grass, which, having been burnt some time, now bore the appearance of young wheat. Six miles down the river it was joined by a fine stream from the southward, apparently watering a spacious valley. We crossed this, and named it Ellenborough River, in honour of the Chief Justice of England. We proceeded about three miles farther before we halted at the edge of a thick detached brush [Note: Many very beautiful shrubs inhabit these shaded thickets, of which the following may serve as a specimen. Tetranthera dealbata, BROWN'S PRODR.; Cryptocarya glaucescens, BR., genera of laurinae. The Australian sapota fruit, Achras australis, BR.; Cargillia australis, a date plum. Myrtus trinervia of Smith, and Ripogonum album, BR.], which came nearly down to the water's edge. In this brush was a quantity of fine red cedar trees, affording us reason to hope, that this valuable wood might, as we advanced to the coast, be found in yet greater abundance. The timber generally might be termed heavy, consisting of blue gum, stringy bark, and iron bark, with fine forest oaks. The stones on the surface of the land were hard and splintery, being principally of coarse quartz; some hard sandstone was also seen: the rocks in the river were of a fine dark blue colour, singularly hard and slippery. Although we had seen no natives, there were abundant signs of them. This season probably is better calculated for them to procure their food on the coast than in the woods.

September 30.—Our progress this day was greatly impeded by thick brushes, which, covering the sides of the hills, ended on the river: some of them were upwards of a mile in extent, and we were obliged to cut a road to enable the horses to pass through them. There were several rich flats on both sides of the river; the hilly projections ending alternately at the several bends of the stream. The obstruction offered by the brushes excepted, the road was no wise difficult: the hills were stony, with rocky summits: the river's course was over large rocks and pebbles; it was fordable in several places, with intervening deep reaches. It was late in the afternoon before we had accomplished six miles, and halting on a flat bounded easterly by extensive brush, I resolved to cross the river. There appears to be plenty of fish in it; we caught six fine perch, weighing above two pounds each, in a very short time. The timber continues heavy and good: we saw however but little cedar after passing the first brush.
