Crossing an open forest hill, which had hitherto bounded our view to the westward, I perceived a deep gra.s.sy valley on our right, sloping towards a much lower country, but I still travelled westward, in hopes to find an open country, beyond a low woody range on which we had at length arrived.
I soon, however, perceived rocky gullies before me, and having halted the party to examine them, I found they were quite impa.s.sable. Such an unexpected obstacle, on the horizon of the fine open country, yet UNDER that smooth horizon, was certainly as singular as it was unexpected, and I returned to descend into the deep gra.s.sy valley I had seen on our right, which seemed open and inviting. We therein also found some large ponds of water, and encamped. While the men were pitching the tents I rode down the valley about two miles, and found that the direction of the water-course was about north-east. Such a direction was not very favourable for us, and I resolved to look at the country beyond the limits of this valley to the westward, before we followed it further.
Lat.i.tude, 24 17" 42" S. Thermometer, at sunrise, 19; at 4 P. M., 66; at 9, 49. (L.) 1279 feet above the sea.
15TH JULY.--Following up a flat which came from the N. W., I proceeded about five miles amid overhanging precipices, until, at length, mighty rocks rendered it quite impossible to push my horse further. Leaving him in a hollow, I ascended a rocky point, which was barely accessible with Yuranigh"s a.s.sistance, and, on reaching an elevated summit, I saw still worse gullies before us, amongst which I could perceive no feature affording any cue to their final outlet, nor any characteristic of the structure of these labyrinths. I looked in vain for the rugged summits I had seen peeping over the plains when first discovered, and could not then be convinced (as I found long afterwards, on completing my map), that they were then under my feet. The highest parts seemed to extend south-westward. To cross such a region with our carts, was quite impossible, and I could only return, and, however reluctantly, follow down the valley in which we had encamped, until it should afford access to a more open country. The banks of the watercourse were steep, the bottom was sandy. The course was very tortuous, alternately closing on rocky precipices, at each side of the valley. Thus we were obliged to cross at every turning, and the steep banks rendered each crossing a difficult operation, occasioning so much delay, that after crossing ten times, evening obliged us to encamp, although our direct distance from the last camp did not exceed five miles. We had, at each crossing, cut the banks, filled up hollows with logs, etc. The general direction, I ascertained to be N.E. Water was found providentially near the spot, where the approach of night had obliged us to encamp; this having been the first water we had seen during that day"s laborious journey.
Thermometer, at sunrise, 21; at 4 P.M., 65; at 9, 44.
16TH JULY.--After some examination of the valley before us, I considered it best, upon the whole, to travel in the bed of the river itself, and thus avoid the frequent necessity for crossing with so much labour and delay: the sandy bed was heavy for the wheels, and therefore distressing to the animals, and one or two rocky ma.s.ses obliged us to work out of it, to get round them. The whole day was consumed in proceeding thus about 5 miles, and in an easterly direction. The closing in of the valley lower down, seemed to shut us from further progress even so, and I encamped, rather at a loss how to proceed. Just then Mr. Stephenson came to inform me that he had seen, from a rocky point on the left, an opening to the north-west, and level ground beyond it. I therefore determined to accompany him next day, and to reconnoitre the country in that direction.
By digging in the bed of the creek, water was again obtained by Corporal Graham. Some extremely fragrant shrubs were discovered in these rocky recesses, especially one, which filled the air with perfume to a great distance around. It seemed to be a EUCALYPTUS without flowers or fruit, but with a powerful odour of balm, and formed a bush five feet high, growing on sandstone rocks, having a narrow leaf, and rather th.o.r.n.y stalk. The lower leaves were also rough.[*] There was another bush, with leaves of the same shape, and glossy, but having a perfume equally strong of the lime.[**] We regretted much, that neither the seed, flower, nor fruit of these interesting shrubs could be obtained at that season. In that valley, we saw also the DAUCUS BRACHIATUS, an inconspicuous weed, and MYOPORUM CUNNINGHAMII. The soft leaved ACACIA PODALYRIOEFOLIA began to indicate its flowering season, and we found a magnificent new crimson CALLISTEMON with its young flowers and leaves wrapped in wool.[***] A new DODONOEA with wingless, 3-cornered, 3-celled fruit[****]; a new species of AOTUS, with narrow h.o.a.ry leaves[*****], and one of the forest trees was a splendid new GEIGERA, with broad lance-shaped leaves.[******] The PLATYZOMA MICROPHYLLUM, a very singular and little known fern, with narrow leaves and small orbicular leaflets, was also there, with the ACACIA FALCATA, ACACIA EXCELSA, and a s.h.a.ggy-leaved variety of the AJUGA AUSTRALIS, the Australian bugle. The BRUNONIA SERICEA, with its scabious- like heads of flowers, was common; and the blue flowered HARDENBERGIA MONOPHYLLA was observed among the gra.s.s. Thermometer, at sunrise, 25; at 9 P.M., 41.

17TH JULY.--Our ride this morning soon led amongst different scenes. By merely turning to the left we came upon a flat, in which another water- course, similar to that we had been tracing (Balmy Creek), came from the west, apparently out of that inaccessible country, across which I had previously looked in vain for a pa.s.sage. Several other gullies joined this water-course, and seared the flat, which consisted of a deep clay deposit, in almost every direction. After crossing these, we found a fine broad opening between rocky precipices of most picturesque forms. This gap I called Stephenson"s Pa.s.s; it led into a s.p.a.cious glen surrounded on all sides but the N.W. by mountains such as I have described, recalling to my memory the most imaginative efforts of Mr. Martin"s saepia drawing, and showing how far the painter"s fancy may antic.i.p.ate nature. But, at the gorge of this valley, there stood a sort of watch-tower, as if to guard the entrance, so like a work of art, that even here, where men and kangaroos were equally wild and artless, I was obliged to look very attentively, to be quite convinced that the tower was the work of nature only. A turret with a pointed roof, of a colour corresponding, first appeared through the trees, as if it had been built on the summit of a round hill. On a nearer approach the fine tints of the yellowish grey rocks, and the small pines climbing the sides of a hill abruptly rising out of a forest of common trees, presented still a very remarkable object. I named the valley "Glen Turret," and this feature "Tower Almond," after an ancient castle, the scene of many early a.s.sociations, and now quite as uninhabited as this. Pa.s.sing through Glen Turret, we ascended the nearest summit on the right, and from it beheld a prospect most cheering, after our toils amid rocky ravines. On the westward, the rocky range seemed to terminate abruptly towards the north, in an elevated point, which seemed to command an extensive view over the unknown W. and N.W. Out of that region two isolated mountain ma.s.ses arose from an open country, and were clothed with open forests to their summits. Further eastward, ma.s.ses of mountain in the extreme distance appeared covered, also, with open forests, and presented finely rounded outlines, not likely to impede our pa.s.sage, in any direction. But towards the N.W. our view was not so extensive; like the uncertain future, it still lay hid. The retrospect was very extensive, including Mount Faraday in the extreme distance, and which thus afforded me a valuable back angle for the correction of our longitude from any errors of detailed survey.
The lofty ma.s.s of Buckland"s Table Land still overlooked all from the E., and I could here again intersect its three princ.i.p.al points. The view back to the Pa.s.s was very fine, for the rocks and wood were so blended on the bold summits, as to present sublime studies for the artist. Far to the westward, an interior line of cliffy range resembled a sea beach, presenting a crescent, concave on that side, apparently the limit to the basin of the Nogoa, and the dividing range between eastern and western waters. Our Pa.s.s seemed to be the only outlet through the labyrinths behind us. Even the open plains beyond them were visible in a yellow streak above the precipices. Far beyond these plains, Mount Faraday was distinctly visible, on the horizon of the landscape. Thermometer, at sunrise, 29; at 9 P.M., 43. (LI.) 1234 feet above the sea.
18TH JULY.--By retracing our horses" footsteps, the carts were soon brought to the base of the same hill; deep gullies in the clay having obliged us to pa.s.s close under it, and, indeed, to cross two of its elevated extremities. We found the country beyond, in a N.W. direction, tolerably open, and we encamped in a valley containing abundance of gra.s.s, and near to our camp, water was found in a chain of ponds descending to the eastward. A new SUAEDA, with short leaves, and the habit of a dwarf Tamarisk, was found this day.[*] Lat.i.tude, 24 6" 47" S.
Thermometer, at sunrise, 31; at noon, 65; at 4 P.M., 69; at 9, 44.
(LII.)
[* S. TAMARISCINA (Lindl. MS.); fruticosa, ramosissima, foliis brevibus cylindraceis imbricatis obtusissimis, axillis lanatis, floribus solitariis sessilibus.]
19TH JULY.--With the intention to lose no opportunity of getting further to the westward, I travelled on towards the base of the most northern summit of the range in the west; but I was, at length, so shut up by gullies and scrubby extremities near its base and all radiating from it, and becoming very deep, that I took the party aside into a gra.s.sy ravine near, where I directed the men to encamp, and hastened myself to the summit. From it, the view westward was not so extensive as I expected.
Something like precipitous slopes to some channel or water-course, apparently falling either S. W. or N. E., formed the most promising feature; but, although my object was to have travelled in that direction, the scrub seemed too thick to admit of a pa.s.sage. Open forest land appeared to the N. E., and there, the gently undulating features, although much lower than the range on whose northern extremity I then stood, seemed nevertheless to form a connection between it and some higher ranges of open forest land, that appeared between me and the coast. Through one wide opening in these, about east, I saw some broken hills, at a very great distance, say seventy or eighty miles. The ridgy- connected undulations formed the heads of some valleys sloping to the south-east, whereof the waters would evidently join those of the Balmy Creek, while others, rising on the north-west side, seemed to belong to a separate basin, and to form a river falling to the north-west. This river was indicated only by slopes meeting and interlacing in a valley. To the left or westward of that supposed river channel, a mighty isolated mountain ma.s.s shut out any view of the further course of the water of the valley formed between it and these slopes; but, as the very lowest point of the whole horizon, as indicated by the spirit-level of the theodolite, lay in that direction, I determined to pursue that bearing, (10 W. of N.) through the open forest country that intervened. I found that the mountain commanding this view, was elevated 2247 feet above the sea, according to the Syphon barometer, and in using this instrument, I could not forget Colonel Mudge, who had kindly taught me its use; I therefore named that summit Mount Mudge. In the gravel at the base of the hill, were water-worn pebbles of trap and basalt. The rock of which the range itself consisted, seemed to be a calcareous grit, with vegetable impressions, apparently of GLOSSOPTERIS BROWNII. On descending to the camp, I was informed that the cattle-watering party came suddenly upon two natives, one of whom was a placid old man, the other middle-aged.
Corporal Graham did all he could to allay their fears, and convince them that they were in no danger from such strangers. The elder at length handed his little bundle to the younger and sat down, on seeing the Corporal"s green bough; meanwhile the other walked on. When Graham took the old man"s hand, and shook it, also patting him on the back, and expressing a friendly disposition only, the poor helpless man of the woods burst into tears, finding himself incapable of either words or deeds suitable for a meeting so uncommon. They could not relieve him from this state of alarm, so readily as by leaving him sitting, and moving on, which they did. In the scrubs near this camp, Mr. Stephenson discovered a very remarkable tree, apparently a casuarina, having long drooping leaves, hanging like long hair from its upper boughs[*]; and in the stony gullies a DODONAEA allied to D. SALSOLIFOLIA A. CUNN., from Van Diemen"s Land, but the leaves slenderer, and three or four times longer[**].
Although we were approaching the tropics, the weather was most cool and pleasant. A delicious breeze played amongst the woods, and welcomed us to the Torrid Zone. Until now, during every clear night the air had been frosty. Lat.i.tude, 24 6" 50" S. Thermometer, at sunrise, 34; at noon, 68; at 4 P.M., 61; at 9, 47.

20TH JULY.--AFTER a little trouble with the gullies and brigalow scrub, on first setting off, we came upon fine undulating open forest land, and crossed many a gully and small water-course, all declining towards the N.E. A very remarkable flat-topped hill appeared on our right, resembling a wart, on one of these ridges; to the northward it was precipitous, and seemed to consist of a very red rock. At length, after crossing a ridge rather broader than the rest, with some brigalow scrub upon it, and one or two specimens of that tree of solitary places, the bottle tree, (DELABECHEA) we arrived at valleys and water-courses descending to the southward of west, into a valley turning to the N.W. One, at length, on our right, taking the direction in which I was proceeding, viz., 10 W.
of N., I followed it down, and thus entered a broader valley leading N.W.
Following this, on a wide flat of open forest, we found at length a fine pond of water in it, and encamped beside it, after a journey of about twelve miles. This valley seemed to continue to the base of the lofty isolated mountain already mentioned, where a lower valley crossed it, falling either to the northward or southward. This I left in pleasing uncertainty until next morning, for I had remarked in that locality, when I stood on Mount Mudge, a long line of grey mist running north and south.
I named the large mountain beyond that valley, Mount Beaufort, in honour of my scientific friend at the Admiralty. Thermometer, at sunrise, 40; at noon, 66; at 4 P.M., 73; at 9, 62. (LIII.)
21ST JULY.--On following downwards the chain of ponds and broad valley, we came upon the bed of a river, running to the N.N.E. We gladly turned in that direction, and after it had received various tributaries from the south, I found it took the course I had foreseen it must from Mount Mudge. We saw water in the channel, and now again I believed that we had at length discovered the head of a northwestern river. The soil consisted of firm clay, and tributaries occasionally impeded our journey. We got amongst brigalow scrub, and could find no water in looking for the channel of the river, which we knew must still have been on our left.
Ponds in the scrub could not easily be identified as channels. I met with no better success on turning to the left, and encamped amongst the brigalow, where I found some gra.s.s. On riding westward I came upon arid stony ground, on which many of the trees were dead, apparently from drought, and so near the Tropic such a scene was by no means encouraging.
On turning my horse, he trod on an old heap of fresh watermussles, at an old fireplace of the natives. This was a cheering proof that water was not distant, which was further indicated by the flight of two native companions, from the N.W. We had encamped on a flat of clay, on which salsolaceous bushes, such as grew on similar plains on the Bogan, had been growing, but were then all withered from drought. The very gra.s.s seemed parched and useless. I never saw vegetation so checked by drought.
A longer continuance was likely to kill all the trees, and convert the country into open downs. I determined, before I ventured further, to send the cattle to a pond four miles back, next morning, and to examine the country before us. Lat.i.tude, 23 48" 36". Thermometer, at sunrise, 57; at noon, 69; at 4 P.M., 75; at 9, 48.
22D JULY.--Having sent bullocks, horses, and sheep back to the water, I went forward on the bearing of 30 W. of N. I soon fell in with the united channel of the river, and found in it abundant ponds of water, the direction of the course being as favourable as could be wished. From these ponds I perceived a clear hill to the westward, which I hastened to ascend, and from its summit I beheld some fine mountains to the northward, although an easterly wind and sea air brought a haze over them, which soon obscured some of my points. But I saw enough to relieve me of all anxiety at that time about the want of water. A promising valley from the mountains in the eastward, came due west, and from it arose the smoke of many natives" fires. Lines of other rivers, from other ranges, were partly visible beyond, until the haze obscured the outlines of mountains still more remote. The bright prospects of this morning were a pleasing contrast to the temporary difficulties of yesterday. Such is human life in travelling, and so it was in war at Salamanca this day thirty-four years back. We encamped after a short journey on the bank of the river. Lat.i.tude, 24 46" 46". Thermometer, at sunrise, 49, at noon, 74; at 4 P.M., 73; at 9, 64. (LIV.)
23D JULY.--The water in the adjacent pond was trodden into mud, so that none remained for the horses and bullocks this morning. Accordingly, on arriving at a pond about two miles on, we gave water to all, that they might better bear the privation in the afternoon, should we not fortunately find more. The river had a singular tendency to spread into little channels within a belt of brigalow scrub. The little holes formed by these channels were almost all dry, while the withered state of the gra.s.s, and even of the forest trees, showed that rain had long been due, and we therefore hoped some would fall before our return. When we had travelled about twelve miles, keeping as close to the river line as the scrub would permit, and crossing one or two fine rising grounds covered with a very open forest, and consisting of large gravel, I found a pond, and encamped near it, on a plain of almost naked clay. Amongst the water- worn pebbles, of which the rising ground consisted, there were, besides the ingredients of the Barwan gravel, many of trap and basalt. Very old and dry gra.s.s only, could be had for the cattle. In the pond were small fishes of a different form from any we had seen, having a large forked tail, only two or three spikes in the dorsal fin, and a large jet-black eye within a broad silvery ring. Mr. Stephenson found three crabs, apparently identical with those about the inlets near Sydney. Lat.i.tude, 23 37" 51". S. Thermometer, at sunrise, 46; at noon, 73; at 4 P.M. 80; at 9, 55. (LV.)
24TH JULY.--The morning was overcast by heavy clouds, and the air was balmy and mild, reminding us of the spring season near Sydney. Lightning had been seen to the northward during the night. In following the little wayward channel downward, we met with much brigalow scrub, and crossed two apparently important tributaries. In one of them was a good large pond. We had some trouble with an ana-branch, resembling the main channel, which we had twice to cross at a distance of two miles. With the last tributaries, plains and an open forest country became neighbours to the river; and where we encamped beside it, no scrub was to be seen, and the water lay in a deep broad reach, nearly half a mile in length, with ducks upon it. Towards evening, the unwonted sound of thunder was heard in the west, reminding us, at this season of the year, that we were near the Tropic. In the same direction, two distant storms exhausted themselves, and most likely giving birth to young gra.s.s where they fell.
During the night, much thunder was heard, and also early next morning, to the northward. Lat.i.tude, 23 31" S. Thermometer, at sunrise, 56; at noon, 75; at 4, P.M., 82; at 9, 66. (LVI.)
25TH JULY.--There was no hill or other geographical feature near our route, whereby it might have been possible to mark there the limit of Tropical Australia. We were the first to enter the interior beyond that line. Three large kangaroos hopping across a small plain, were visible, just as we entered these regions of the sun. The air was extremely fragrant; the shrubs and gra.s.s being still moist with the thunder-shower.
The course of the river continued favourable, and the country seemed to improve as we advanced, opening into plains skirted by scrubs of rosewood, and drooping shrubs whose verdure was most refreshing to the eye, after just having pa.s.sed through dry and withered brigalow. At eight miles a large lagoon appeared on our left, on which we saw many ducks, and at nine miles we encamped where the gra.s.s seemed good, finding that water was at hand now, in the river bed, wherever we required it.
Lat.i.tude, 23 25" 26" S. Thermometer, at sunrise, 45; at noon, 77; at 4 P.M., 85; at 9, 53. (LVII.)
26TH JULY.--The river appearing to pursue a W. N.W. course, I set out in that direction, attracted there, also, by some open plain separated by scrub from the river. We travelled on, a good many miles, when, instead of the firm clay, we found, under foot soft, red sand, and trees of the genus callitris growing in close thickets. I turned to the northward, and travelled many miles to the eastward of north, without seeing any indications of the river, whose general course had been previously straight. Scrubs of almost every description lay in our way. Brigalow, rosewood, casuarina, a thick light-green scrub of a close-growing bush, new to us, and some scrubs of the tree as yet undescribed for want of flowers or fruit, although well known to us as a graceful, and, indeed; useful bush; of which, as an impediment, we could not much complain; and useful, as forming excellent whip-shafts. This is the tree of unknown fruit figured in my former journal. At length, when it was growing late, I travelled eastward to make sure of the river, and, at length, regained its banks, where we found in its bed plenty of water. The surface looked bare, and the gra.s.s dry; but this day I discovered green shoots amongst it, evidently the product of recent rain, and indicating the approach of spring. On sandstone rocks, we found a plant which Sir William Hooker terms "a singular Euphorbiaceous (?) plant[*]," dest.i.tute of flower and fruit. Branches very thick, and they, as well as the long petioles and underside of the leaves clothed with dense white wool. Leaves a span long, cordato ac.u.minate; the laminae all pointing downwards, glossy green and glabrous above. Also a new DODONOEA, with very narrow, linear, pinnated leaves. The only hills visible, from a tree ascended by Yuranigh, during this day"s journey were those to the eastward, already seen. None appeared above the horizon in any other direction.
Thermometer, at sunrise, 39; at noon, 79; at 4 P.M., 89; at 9, 75.

27TH JULY.--The same characteristic, still distinguished our river; a variety of channels, so concatenated amongst brigalow scrub, much whereof lay dead, that it was scarcely possible to ascertain whether there was any main channel. Hitherto, I had not detected one; but this was of little consequence to us, so long as these ponds contained abundance of water. This we saw in many parts of our route this day; for I kept as close as possible to the river"s course, to avoid such detours as that of yesterday, and being very anxious about the river"s general direction, I was glad to find it turn somewhat westward of north. After travelling thus about nine miles, I perceived a blue pic nearly due north, which I named Mount Narrien; and Yuranigh saw from a tree, that there was a range in the same direction, but very distant. This seemed likely not only to send down some additional waters to our river, but also to turn it westward. Entering, soon after, upon a plain of good gra.s.s, I looked for water; and, on finding some, encamped after a journey of about eleven miles. Lat.i.tude, 23 9"S. Thermometer, at sunrise, 43; at noon, 83; at 4 P.M., 90; at 9, 53. (LIX.)
28TH JULY.--The brigalow scrub, still a concomitant of our river, so hemmed in the patch of plain, that I was obliged to move out of it, in a southerly direction. Even thus, however, the scrub was not to be avoided, and we were obliged to force a way through, where the still more formidable impediment of much fallen timber, rendered it almost impossible that our vehicles could pa.s.s. This dead wood seemed peculiar to that sort of brigalow, and appeared to remain unburnt, chiefly from the usually naked surface of the ground where brigalow grows. I left the party, when brought almost to a stand, and sought for a more open part, by riding northward. This rather singular river seemed to have spread over a considerable extent of surface, and much of the brigalow, however fond of water, appeared to have died of too much, on spots which had been flooded. I traversed a plain, beyond which I found, what seemed there, the main chain of ponds or channel. There was a fine reach of water, and beside it, were the still smoking fires, water-vessels, etc., of a tribe of natives, who had disappeared. On the plain, the remains of decayed stumps of brigalow showed that there also, this tree had once grown, and that the openings were caused only by such trees perishing; as if, according to seasons, the half-dead scrub might either give place to open downs, or, that the plains might, by long succession of regular seasons, become again covered with scrub. I returned to the party halted in the scrub, and conducted it through an opening I had found, to the plain, and across it, in a N.W. direction; where, after pa.s.sing through some open forest, we had again to contend with brigalow. One of the many dry channels a.s.sisted us much in seeking openings, as the bottom then consisted of smooth, firm, clay. A pond, however, obliged us to quit it, and seek our way through the wood. We arrived next at slightly undulating ground, and finally entered an open forest, where I saw the LORANTHUS SUBFALCATUS of Sir William Hooker. I made Yuranigh climb a tree, from whence he again saw the pic seen yesterday, (the bearing of which I ascertained), and also a gap appeared in the range beside it, through which, as he thought, a river was likely to come down. The extreme westerly escarp of these hills bore 17 E. of N., so that nothing was likely to impede the continued course of our friendly river in the direction we wished. The scrub we met with on the rising ground, consisted of the verdant bushes in rosewood scrubs, and we next found brigalow all dead, with a rich crop of gra.s.s growing amongst the dead stems. I had never seen gra.s.s, amongst brigalow, when in a healthy state.
On turning northward, we next entered upon an open plain covered with good gra.s.s mixed with verdant polygonum. I selected a corner of this plain, nearest to the river, for my camp; and, on approaching its bed, found water as usual, near some old huts of the natives. Lat.i.tude, 23 5"
20" S. Thermometer, at sunrise, 44; at noon, 82; at 4 P.M., 88; at 9, 58. (XL.)
29TH JULY.--The scrub between our camp and the river, admitted of easy access from it to open forest ground, over which we travelled in a N.W.
direction for several miles. Belts of scrub, consisting of rosewood and other acacias intervened, and, in some parts, TRIODIA PUNGENS grew in the place of gra.s.s. But, upon the whole, the country was fine, open, park- like, and with much anthistiria, and other gra.s.ses in which a greenness was observed quite novel to us, and unexpected in these tropical regions.
Amongst the shrubs, we recognised the Ca.s.sIA HETEROLOBA, a small yellow- flowered shrub; also a glutinous Baccharislike plant, and a form of Eremophila Mitch.e.l.lii, intermediate between the two other varieties. This was a shrub ten feet high. Another new species of the genus GEIJERA formed a tree twenty feet high, with long slender weeping branches. It was otherwise much like the GEIJERA PARVIFLORA, except that its flowers were larger.[*] A dwarf shrub belonging to the genus STENOCHILUS, but new, was found here[**]; and we met also with a large spreading tree, from which we could bring away nothing that would enable botanists to describe it, except as to the texture and nervation of the leaves, which, Sir William Hooker observes, resemble CAPPARIDEOE; but the fruit appeared to be sessile, and was too young and too imperfect to lead to any satisfactory conclusion. The very crows cawed differently from those near Sydney, or, (as Yuranigh observed) "talked another language." This river was not the least unique of our recent discoveries. It still consisted of a great breadth of concatenated hollows without any one continuous channel, and this character seemed to be preserved by various trees growing in the banks. When their large roots became denuded by the floods, or were washed out, or partially gave way, so that the tree fell over the stream, they presented impediments, first to the floating-wreck, and, next, to the water itself: when that collection of floating wreck became consolidated with muddy deposit, new banks so formed forced the river into new currents, working out new courses; and this appeared to give the peculiar character so uniformly observed. It seems extremely favourable for the retention of water in a country where it may be scarce; for the many ponds so formed and shaded from the sun, preserve it much better and longer, than if one continuous un.o.bstructed channel alone, received and carried off, the water of the surface. I found the hollows we saw this day drier than usual; but we at length succeeded in discovering three good ponds. The foliage of the trees, with dry and naked water-worn roots, presented all the hues of an English autumn, although none of these were deciduous. This effect I was disposed to attribute to unseasonable drought, or past heat. The weather we had was delightful; for, although the thermometer in the shade rose sometimes to 90 about 4 P.M., the heat of the Bogan was still fresh in our recollection; and the frosts which, not above three weeks before, had disturbed our sleep, made this degree of heat as welcome as the flowers in May.

30TH JULY.--The scrub of the river being likely to surround us, I endeavoured to pa.s.s it, and cross the river, but on examination I found the brigalow belt beyond, so serious an obstruction, that I adhered to the left bank still, and proceeded N. N. W. The woods opened into extensive plains covered with wild Indigo, as high as a horse"s head, and that was skirted by a plain covered with rich gra.s.s. Beyond these, we entered an open forest where the anthistiria grew luxuriantly. I saw, from the skirts of the plain, the ma.s.s of mountains partly seen in the east for several days past, and I was able to intersect various points.
We seemed to be descending to a very low country. A fine large lagoon, covered with ducks, appeared on our right. The whole country was improved both as to gra.s.s and trees. The MYOPORUM DULCE, a shrub about five feet high, was perhaps a distinct species intermediate between M. DULCE and M.
DESERTI. It had the habit of the latter, but the leaves nearly of M.
DULCE. A hollow at length indicated the river bed near us. It contained abundance of transparent water, a continuous channel, rocky bed, and, instead of brigalow, there grew on its banks a thick crop of strong gra.s.s, and much verdure. A tributary from the west cost us some trouble to cross, and soon after crossing it, I encamped. The course this day had run well to the westward. We had crossed the 147 of E. longitude, and I was very anxious to learn more of the further course of this river. I crossed it, and hastened to some rising ground, whence I perceived a flat-topped cliffy range extending from S. W. to the N. of west. It was low; the middle part, appearing highest, was probably the nearest to our camp. It was likely to turn our river too far to the northward for our purpose. Lat.i.tude, 22 51" 55". Thermometer, at sunrise, 54; at noon, 82; at 4 P.M., 83; at 9, 45. (LXII.)
31ST JULY.--We travelled over a rather different sort of country from that recently seen upon the river. It was still on our right, and ran in a deep, well-marked channel. I pursued a N.W. course, although the range I had seen yesterday lay across it. I thus came upon the bed of a large river from the south, very near where our little river joined it. This new river was there fully 100 yards broad, with a sandy bed. I hastened across it, and proceeded still N.W. In the bed, just above the junction of the two rivers, I found a large podded pea, the seed both in green pods and dry pods, was very sweet and edible. The pods were larger than those of Turkey beans, and contained each ten or eleven peas (Dr. L.?) Beyond the last found river, we travelled over open forest land, occasionally pa.s.sing patches of rosewood scrub on the left. When we might again see water was rather a desperate thought, for we had witnessed our abundant little river, wholly absorbed in a deep ma.s.s of dry sand, for such was the bed of the larger. At length we came upon a very s.p.a.cious dry lagoon. Following this, as it appeared to be the channel of large floods from the river, we arrived at a part containing water, and, still continuing along the hard dry bank, another and another pond appeared, and I finally encamped near the last, where I saw some good gra.s.s. The course and character of the river below the junction last mentioned, remained to be ascertained. Parts of the surface in the scrub, which, before the rain, had been quite bare, now presented a crop of lichen, which bore some resemblance to the orchilla. It might have been gathered in any quant.i.ty. The ant-hills in this region, presented a different form from any to be seen in the south, consisting of slender cones of hard clay about the size and shape of sugar-loaves on an average, many being larger, or as much as 3 feet high, others smaller. In some places they were so numerous, as to be rather inconvenient to ride amongst, especially where the gra.s.s was long. Lat.i.tude of this camp, 22 44" 45".
Thermometer, at sunrise, 52; at noon, 70; at 4 P.M., 69; at 9, 43.

1ST AUGUST.--Supposing that this line of lagoons led to the river, I followed that direction westward, until it disappeared where we came upon the water brigalow. Then, turning northward, I travelled many miles in that direction, through rosewood scrubs, and over ground where the very coa.r.s.e hard gra.s.s grew on red sand. The callitris and casuarina appeared amongst the trees. On a spot rather clear of wood, Yuranigh went to the top of a callitris tree, and saw a lofty mountain somewhat to the eastward of north, and he thought he could trace the trees marking the course of the river to the westward of it. Further westward, the low range already mentioned, was still visible, and he saw that the country between the two ranges was very "deep," as he termed it, meaning very low. Upon the whole, there was reason to believe that the river pursued a course, somewhat to the westward of north. I turned in that direction, and forced our way through scrub and brush, until, after cutting through much fallen brigalow, I entered upon good gra.s.sy land, and saw the large Yarra trees before me. These grew by the river, which here looked very important, having a bed wider than that of the Barwan, with sloping gra.s.sy banks at least sixty feet high, and Yarra trees growing from the lower margin. Continuing along its banks, we soon found various large ponds of water, and in the short course of it we had to trace before we encamped, the direction was S. W. Many curious plants and trees now appeared about the banks. A rough-leaved fig tree with well-formed woolly, globular fruit; an ALTERANTHERA, with very large b.a.l.l.s of satiny white flowers, resembling A. NODIFLORA; the ACACIA FARNESIANA, a p.r.i.c.kly tree; the narrow-leaved smooth variety of ACACIA HOLOSERICEA; and in the bed of the river, the ACACIA SIMSII (Cunn.) A broad-leaved form of LORANTHUS NUTANS was parasitical on trees, and the EURYBIA SUBSPICATA of Sir W. Hooker also grew on the upper bank. A very extraordinary CAPPARIS was here observed in fruit. Its leaves were as much as eight inches long, although not more than three quarters of an inch wide, and their hard leathery texture gave them the appearance of straps. It did not afterwards occur.[*] The water in the river was excellent. Thermometer, at sunrise, 23; at noon, 65; at 4 P.M., 69; at 9, 44. Lat.i.tude, 22 38" 40". (LXIV.)
