It was now 3 o'clock P.M., and my Blackfellows had left me, as usual; my horse was foot-sore, and neither the poor animal nor myself had tasted water for the last thirty-six hours. Under these circumstances, though I ardently desired to push on to the north-west ranges, I thought it prudent to return; and after a short rest to my horse, during which I chewed some dry pieces of beef, I rode on my way back until 9 o'clock, and then encamped. The coldness of the night reminded me too strongly of the pleasures of the fire and the heavy dew which had fallen, though a comfort to my horse, rendered it difficult to light one; by dint of patience, however, I succeeded, and then stretched myself, hungry and thirsty as I was, by the side of a large Ironbark log; whilst my horse, which I had hobbled and tethered, drooped his head over me, little inclined either to feed or move. I started early in the morning of the 14th, and passed between Mount Lang and Razorback Hill. At the foot of the latter I met a small creek, which I followed through a long series of plains until I came on my old track, not very far from Big Ant-hill Creek. At the sight of water, which we had been without full fifty hours, my horse and I rushed simultaneously into it, and we drank, and drank, and drank again, before I could induce myself to light a fire and make some tea, which was always found to be much more wholesome, and to allay thirst sooner than the water alone.

Near the large water-hole at which I halted, was an old camping place of the natives, and the remnants of many a hut lay scattered round two large flooded gum trees. The smoke of the natives fires was seen in every direction. This part of the country is doubtless well supplied with water-holes: but as they are unconnected with a watercourse, the traveller, unless by accident, has little chance of finding them.

In returning along Ant-hill Creek, I passed a few native men sitting before their gunyas; they were not a hundred yards from me, yet they remained silent and motionless, like the black stumps of the trees around them, until the strange apparition passed by. At sunset, just as I was taking the saddle from my horse, I heard a cooee, and not considering it prudent to encamp in the vicinity of the natives, I began to tighten up the girths again; but, at the same time, answered the cooee, and soon after I saw Master Charley and his wearied horse descending from the opposite range. He had not had anything to eat since the morning of the preceding day, and was therefore exceedingly pleased to meet me. He had not been able to follow me, in consequence of the foot-soreness of his horse, but he had succeeded in finding a small spring at the foot of Mount Lang, near which the natives had often and recently encamped.

May 15.--We returned to our camp. The natives [These natives are probably the same as, or are connected with, the tribe that frequent Rockingham Bay, who have always been noticed for their friendly bearing in communications with ships visiting that place. Rockingham Bay is situated due east from the position of Dr. Leichhardt's party.--Note by Capt. King.] had visited my companions, and behaved very amicably towards them, making them not only presents of spears and wommalas, but supplying them with seed-vessels of Nymphaea, and its mealy roasted stems and tubers, which they were in the habit of pounding into a substance much resembling mashed potatoes. They took leave of my companions to go to the sea-coast, pointing to the east and east by south, whither they were going to fetch shells, particularly the nautilus, of which they make various ornaments.

May 16 and 17.--We moved our camp about twenty miles N.N.W. to latitude 18 degrees 16 minutes 37 seconds, to one of the head brooks of Big Ant-hill Creek. We travelled the whole distance over the basaltic table-laud without any impediment. The natives approached our camp, but retired without any communication.

I had not found any westerly waters on my ride of the 13th, but had seen a range to the north-west, and that was the goal of a new exploration. As we had been fortunate enough to find water at the contact of the primitive and basaltic formation, I wished to follow the same line of contact as long as it would not carry us much out of our course. We crossed, in a northerly direction, several granitic ranges which ran out into the table land, and were separated from each other by very large swamps, at the time mostly dry, and covered with a short withered swamp grass, but bearing the marks of frequent inundations. The bed of these swamps was perfectly level, and formed by an uninterrupted sheet of basalt. Chains of water-holes between the ranges, which I hoped would lead me to creeks, were lost in the level of these swamps; indeed, these granitic ranges were remarkably destitute of watercourses. The coarse elements of the decomposed rock, principally pegmatite, had formed uniform slopes, in which even heavy showers of rain were readily absorbed; but rounded blocks of rock, sometimes curiously piled, protruded from the granitic sands. Pandanus spiralis fringed the scattered water-holes; and Grevillea chrysodendron, (R. Br.) formed a wreath, of pale silver-colour, round the swamps, but grew on sandy soil. White cranes, the ibis, geese, native companions, and plovers, were very numerous; and the large ant-hills scattered through the forest at the foot of the hills, looked like so many wigwams.

From one of the ranges I had another view of the north-west range, and we started for it, leaving the primitive country behind us. A cold, southerly wind set in on the morning of the 18th, which made Brown and myself shiver, and I most gladly availed myself of a flannel shirt, whilst Brown covered himself with his blanket. We rode about five hours over an undulating forest land, interrupted by one or two plains, and for the greater part exceedingly stony. We came at last to fresh burnt grass, and observed recent marks of the stone tomahawk of the natives; and, having passed a stony slope, with irregular low stony ridges, we saw an oak-tree creek before us, on the opposite side of which rose the granitic range for which we had directed our course. This creek also ran on the line of contact of primitive and basaltic rocks; the primitive side was cut by gullies and ravines, whilst the basalt formed a steep uninterrupted slope, though covered with boulders which had been carried down even into the sandy bed of the creek, where they were intermingled with those of granite and pegmatite. I called this creek "Separation Creek," in allusion to its geological relations: at the point where we met it, it turned to the north and north-west, which made me believe that it was a westerly water; but in this I was mistaken.

We had some slight showers of drizzling rain during the afternoon. The wind veered towards evening to the northward, and the night was clear.

We saw several kangaroos, and their tracks to the water showed that they were numerous. One of them, which we saw in the creek, was of a light grey colour, with rich fur and a white tail.

May 19.--We returned to the camp. A cold easterly wind continued during the day; low rainy clouds in the morning formed into heavy cumuli during the afternoon.
