24TH JUNE.—The hoar-frost had stiffened the grass, and the water was frozen so that the horses cared not to drink. I proceeded N. N. W., in which direction a beautiful cone rose to a great height, and sharp apex. Stony hills of trap appearing also in that line, I turned northward, and, after crossing a level tract of high ground, much like a dividing feature, (especially as seen from Mount Owen,) I entered a valley descending to the northwest. It fell rapidly, contained large water holes, and in two of these, at length, an abundant supply of water. The course, throughout all its windings, was towards the north-west, and this I, at the time, thought, might be a northern water. I therefore returned, anxious to bring the party thus far, at all events, and resolved to follow this little river down. We arrived, on our way back, in the evening of the same day, in the valley I had quitted in the morning, having followed down a water-course from the end of Hope's Table Land, under which I had passed, in search of a good way for the carts. Although we had seen promising ponds of water in this little channel, we could find none in the lower part, having in the expectation of finding some, rode on until darkness prevented me from going further. We were thus obliged to pass the night (a very cold one) without water, and almost without fuel. I missed the comfortable cavern where I had slept a few nights before, especially when I arose here in the night to mend the fire, and found we had no more wood at hand. I learnt afterwards that at the camp, the thermometer at 4 p.m. had been as low as 17° of Fahrenheit.[*] Thermometer, at sunrise, 21°; at noon, 51°; at 4 P. M. 49°; at 9, 29°.
[* This was 15° degrees below the freezing point, and shows how much more easily cold may be endured in a dry atmosphere than where there is moisture, as instanced in the following extract from a despatch of Captain James C. Ross (in command of the Antarctic Expedition), dated 7th April, 1841, and published in the Tasmanian Journal.
"With a temperature of 20° below the freezing point, we found the ice to form so rapidly on the surface, that any further examination of the barrier in so extremely severe a period of the season being impracticable, we stood away to the westward, for the purpose of making another attempt to approach the magnetic pole, and reached its latitude (76° S.) on the 15th February.">[
25TH JUNE.—Continuing our ride as soon as day-light permitted, ten minutes brought us to a pond containing plenty of water under a shelving rock, and here we alighted to breakfast, which was pleasant enough, but not so gratifying as the position of this pond, which would enable me to bring the carts through these valleys, to this convenient intermediate stage in the way to the Northern river. The next question was, whether the route to the eastward, descending into these valleys near Mount Clift, or that by my first route, when I discovered this rocky country, should be preferred; and I returned towards our camp this morning by the eastern gullies, in hopes to find an easy descent nearer to Mount Clift than at the point where I before came down. But I found them much more acclivitous and rocky. We at length, with difficulty, got our horses up a rocky point, on which grew a thick scrub of "blackwood," as Yuranigh called it, an acacia having many tough stems growing thickly together from one root, and obstructing the passage, and covering the ground with its half-fallen and fallen timber. Our passage along the range thence towards Mount Owen, having been too much to the eastward, brought us upon the bend of a gully falling to the Maran; a wild and impracticable looking dell as ever was seen. On regaining our track near Mount Owen, and returning along it to the camp, I found that another pond had been discovered in the valley, by Felix Maguire, who on two occasions, had dreamt of water, risen, and walked directly to where he found it! However that might have been, this man had a happy knack in finding water. In the neighbourhood of this camp some interesting plants were collected; viz. NOTHOCHLOENA DISTANS, GRAMMITIS RUTOEFOLIA, CHEILANTHES TENUIFOLIA, ADIANTUM HISPIDULUM and ASSIMILE, all ferns, together with HOVEA LANCEOLATA, the weedy SPHOERANTHUS HIRTUS, GREVILLEA FLORIBUNDA, a low shrub, occupying the ravines. Besides these we observed a small species of SIDA in the sandy soil of forests, the DOODIA CAUDATA Br., a verdant fern, and the SOLANUM FURFURACEUM with lilac flowers, and small red berries. A shrub loaded with succulent drupes, seated in reddish cups, appeared to be a new species of VITEX, but its genus was uncertain, there being no flowers. What is here called GREVILLEA FLORIBUNDA may have been an allied species, for the leaves were more downy, almost tomentose above. In addition to this a new species of the common genus DODONOEA, frequently met with afterwards, was now producing its flowers.[*] Thermometer, at sunrise, 12°; at noon, 50°; at 4 p.m. 51°; at 9, 22°.

26TH JUNE. The party moved forward, at length, with the certainty of finding water for at least three days' journey, and of a hopeful water- course being before us. Passing by the foot of Mount Owen, I observed the barometer which gave an elevation of 2083 feet: the summit might be 700 feet higher. My plan of route was, to enter the little river that turned to the south-west (as I had found it did, on the 20th,) and to travel along its valley upwards, until I reached the pond near which I had bivouacked on the 25th. This we accomplished most successfully before sunset, encamping beside the large pond already mentioned, near which were two others. The earth by the margin was so soft that neither the horses nor bullocks could approach the water; they could only be watered out of buckets; but the water was excellent, and water of any quality, in abundance too, was to us rather uncommon good fortune, and quite cheering, even when surrounded by soft mud. Thermometer, at sunrise, 14°; at noon, 48°; at 4 p.m. 47°; at 9, 37°.
27TH JUNE. We had next to trace up a grassy valley which seemed to come directly from the vicinity of that in which I had found water and bivouacked on the 24th. It formed an excellent line, and we found it possible to keep this fine firm level surface, until we had approached to within two miles of that spot. Leaving a little hill of trap to the left, and some brigalow scrub on the right, we reached the old ground and encamped. The small ponds had evaporated, but, in the frosty night, the cattle were not likely to require water, as they had been watered on the way, about 3 p.m., at a rocky well in the valley. We had now traced with our wheels, a good way through a country much broken and shut up by sandstone gullies; but which contained also many rich valleys, and extensive hilly tracts of trap rock, on which the grass was very luxuriant, apparently available for either sheep or cattle. Immediately to the westward of this camp (marked XXXVIII.) an extensive valley was bounded by the fine trap range of Hope's Table Land; which range was open along the summit, and contained springs, in various ravines along its sides. In these ravines, we first saw the arborescent Zamia, and various remarkable shrubs; the MYOPORUM CUNNINGHAMII of Swan River, forming a shrub six feet high, with white fragrant flowers. Thermometer, at sunrise, 20°; at 9 p.m., 29°. Height above the sea, 2064 feet.
28TH JUNE.—Severe frost whenever the sky was clear, seemed the ordinary weather of that country, at that season; showing, as the barometer also indicated, that we were at a great height above the sea. I sent the party forward, guided by Yuranigh, along my former track, to the ponds in the newly discovered channel, falling north-west; and I proceeded myself, accompanied by Mr. Stephenson, to the summit of the fine cone already mentioned. From this, I beheld a splendid and extensive view of the mountains further northward. Most of the summits I had previously intersected, and many others, very remarkable, just appeared over an intermediate woody range, through which I was at a loss to discover where our supposed northern river would pass. Far in the north-west, I could just distinguish the tops of curiously broken hills arising from a much lower country; and therein I hoped to find, whatever might be the final course of our river, a passage to the north-west, and water. The most important feature in that scene seemed to me to be a grey misty tint, as if it marked a valley descending from the highest eastern mountains, towards the curiously broken summits in the northwest. Bare crests of similar hills, appeared to arise throughout the whole extent of that valley. Under those lofty mountains, at such elevation, in such a clime, with these romantic hills, that valley must be a paradise if watered well, as I hope it is. So flowed the "spring" of hope at least, as it was fed by the scene then before me. The cone we had ascended consisted of trap rock, much resembling that of Mount Aquarius; but, at its base, and on its sides, I found in large masses, the very compact felspathic rock which characterises the valley of the Darling. This has been considered a very fine-grained sandstone; but it is evidently an altered rock. Here, in contact with trap, it possessed the same tendency to break into irregular polygons, some of the faces of which were curved; and I observed one mass which had been so tossed up, that its lower side lay uppermost, inclined at an angle of about 60°. That this is a hypogene rock, sometimes in contact with granite as well as with trap, is evident at Oxley's Table Land, and other places. I was glad to find it here, as affording a prospect of meeting with better soil than the loose sand we had seen so much of. We here found the grey, prickly SOLANUM ELLIPTICUM. I named this cone Mount P. P. King; and, I have since ascertained, by that officer's register and calculations, the height of this summit above the sea, to be 2646 feet; and the height of this camp, 2159 feet. Thermometer, at sunrise, 25°; at 4 p.m., 55°; at 9, 25°. (XXXIX)
29TH JUNE.—Crossing a small tributary which was full of water (coming from Hope's Table Land), we continued to travel along the left bank of the newly found river. Rocky precipices overhanging it, obliged me to make some détours, and to pass through some scrubs; but still we regained the banks of the river, although our progress was not considerable. Its general course was still north-west, to the spot selected for my second camp on its banks. The channel was now broad; the banks high, rounded, and grassy; in some places, rocky. Water in the channel was rarely to be seen, but at the junction of tributaries, where recent temporary showers seemed to have fallen. By careful observation, I ascertained the variation of the needle to be 8° 4' E. here. Thermometer, at sunrise, 25°; at 4 p.m., 68°; at 9, 53°. Height above the sea, 1914 feet. (XL.)
30TH JUNE.—The course of the river was now found to turn to the southward of west; and, even in that direction, rugged cliffs covered with scrub greatly impeded our progress. I endeavoured to conduct the carts along the bed of the river, soft and sandy as it was; but we did not proceed far in it, before rocks, fallen trees, and driftwood, obliged us to abandon that course as speedily as we could. Then, ascending a projecting eminence, we plunged into the scrubs; but, even in a southwest direction, we came upon the river. Pursuing its course along the bank, southward, I arrived near the base of a fine open forest hill; and, directing the party to encamp, I hastened to its summit. I there obtained a view of most of the mountains of the eastern range formerly observed, and enough of the fixed points, to enable me to determine the position of this. In the south-west, a line of open forest, and a vast column of smoke seemed too plainly to mark the further course of our river; but, towards the north-west, I saw much to reconcile me to this disappointment. Summits of broken and uncommon aspect, beyond an intervening woody range, there indicated a much lower and different kind of country, as if that was, indeed, the basin of a system of northern waters; the woody intervening range appearing to be the division between them. As our last explored river again turned southward, it seemed reasonable to expect, beyond that very continuous range, rivers pursuing a different course. This range was plainly traceable from the high mountains more to the eastward, and was continuous westward to three remarkable conical hills, beyond which, the view did not extend. On the same range, a fine tableshaped mountain appeared nearly north. This I had already intersected from other stations, and named Mount Faraday. The hill on which I stood consisted of trap-rock, and seemed to be almost the western extremity of Hope's Table Land. A copious spring was afterwards found by Mr. Stephenson, in a valley to the eastward of this summit. That ravine was extensive; and in it grew various remarkable trees. The bottle-tree (Delabechea) grew more gregariously than we had ever seen it, in the stony banks of the channel of the torrent from the hills. One thorny tree or shrub (first seen at the base of Mount P. P. King) again appeared here; it was, generally, in a withered state; had a leaf somewhat like the human hand, and a pod containing two peas of a bright scarlet colour, about the shape and size of a French bean. This, sometimes grew to a tree as much as a foot in diameter; and the natives, who, like Nature herself, may be said to do nothing in vain, had cut one down, and carried off the whole of the trunk. The wood was of a leaden colour. This proved to be a new species of ERYTHRINA, or coral tree.[*] By our last day's journey, we had lost two miles of northing, and had thus recrossed the 25th parallel of south latitude. I therefore determined to cross our friendly little river, and look for another beyond the range to the northward. Thermometer, at sunrise, 44°; at noon, 68°; at 4 p.m., 65°; at 9, 38°. Height above the sea, 1732 feet. (XLI.)
