The gum-trees on this creek were of considerable size; and many of the shrubs we had found in the creek, at the glen, were in beautiful flower in its broad and gravelly bed, along which the Clyanthus was running with its magnificent blossoms; a situation where I certainly did not expect to find that splendid creeper growing. It was exceedingly curious to observe the instinct which brought the smaller birds to our well. Even whilst Morgan was digging, and Mr. Browne and I sitting close to him, some Diamond birds (Amandina) were bold enough to perch on his spade; we had, in the course of the day, whilst passing over the little stony range, been attracted to a low Banksia, by seeing a number of nests of these little birds in its branches, and of which there were no less than fourteen. In some of them were eggs, and in others young birds; so that it appeared they lived in communities, or congregated together to breed. But we had numberless opportunities of observing the habits of this interesting little bird, whose note cheered us for months, and was ever the forerunner of good, as indicating the existence of water.
We placed the cart under a gum-tree, in which the cockatoos we had alarmed when descending into the creek had a nest. These noisy birds (Plyctolophus Leadbeaterii) kept incessantly screeching to their young, which answered them in notes that resembled the croaking of frogs, more than anything else.
On the 11th we left the creek, well satisfied with our night's occupation of it, as also, I believe, to the still greater satisfaction of our noisy friends. For about two and a half or three miles there was every appearance of an improving country It was open, and in many places well covered with grass; and although at three miles it fell off a little, still the aspect on the northern side of the creek was, to a considerable distance, preferable to that on the south side. At 11 a.m. we gained the crest of the little stony hill we had seen the day before to the N.N.W., and from it were enabled not only to take back bearings, but to carry others forward. We were fast losing sight of the hills, whose loftier summits alone were visible, yet we now saw fresh peaks to the north, which satisfied me that they continued in that direction far beyond the most distant one we had seen. From this circumstance I was led to hope that we might fall on another creek, and so gradually, but surely, work our way to the N.W.
On descending from the little hill, however, we traversed an inferior country, and at two miles saw a few scattered Pine-trees. Shortly afterwards, on breaking through a low scrub, we crossed a ridge of sand, on which numerous Pine-trees were growing. These ridges then occurred in rapid succession, separated by narrow flats only; the soil being of a bright red clay covered with Rhagodiae, and having bare patches on them. The draught over this kind of country became a serious hindrance to our movements, as it was very heavy, and the day excessively hot, the horses in the team suffered much. I therefore desired Morgan to halt, and, with Mr. Browne, rode forward in the hope of finding water, for he had shot a new and beautiful pigeon, on the bill of which some moist clay was adhering; wherefore we concluded that he had just been drinking at some shallow, but still unexhausted, puddle of water near us: we were, however unsuccessful in our search; but crossed pine ridge after pine ridge, until at length I thought it better to turn back to the cart, and, as we had already travelled some 25 miles, to halt until the morning; more especially as there was no deficiency of grass on the sand ridges, and I did not apprehend that our horses would suffer much from the want of water.
Whatever idea I might have had of the character of the country into which we had penetrated, I certainly was not prepared for any so singular as that we encountered. The sand ridges, some partially, some thickly, covered with Pine-trees, were from thirty to fifty feet high, and about eighty yards at their base, running nearly longitudinally from north to south. They were generally well covered with grass, which appeared to have been the produce of recent rains; and several very beautiful leguminous plants were also growing on them. I did not imagine that these ridges would continue much longer, and I therefore determined, the following morning to push on. Our position was in lat. 30 degrees 40 minutes S. and in longitude 140 degrees 51 minutes E. nearly.
On the morning of the 12th we commenced our day's journey on a N.W. course, as I had proposed to Mr. Browne. Flood had been about half a mile to the eastward, in the hope of finding water before we rose, but was disappointed; the horses did not, however, appear to have suffered from the want of it during the night. On starting I requested Mr. Browne to make a circuit to the N.E. for the same purpose, as we had observed many birds fly past us in that direction; and I sent Flood to the westward, but both returned unsuccessful. Nevertheless, although we could not find any water, the country improved.
The soil was still clay and sand, but we crossed some very fine flats, and only wanted water to enjoy comparative luxury. Both the flats and the ridges were well clothed with grass, and the former had box-trees and hakeas scattered over them; but these favourable indications soon ceased. The pine ridges closed upon each other once more, and the flats became covered with salsolaceous plants. The day was exceedingly hot, and still more oppressive in the brushes, so that the horses began to flag. At 2 p.m. no favourable change had taken place. Our view was limited to the succeeding sand hill; nor, by ascending the highest trees, could we see any elevated land at that hour; therefore I stopped, as the cart got on so slowly, and as the horses would now, under any circumstances, be three days without water, I determined on retracing my steps to the creek in which we had dug the well. I directed Mr. Browne, with Flood, however, to push on, till sunset, in the hope that he might see a change. At sunset I commenced my retreat, feeling satisfied that I had no hope of success in finding water so far from the hills. Turning back at so late an hour in the afternoon, it was past midnight when we reached the sand ridge from which we had started in the morning; where we again stopped until dawn, when proceeding onwards, and passing a shallow puddle of surface water, that was so thick with mud and animalculae as to be unfit to drink, we gained the creek at half-past 4 p.m. Mr. Browne and Flood joined us some little time after sunset, having ridden about 18 miles beyond the point at which we had parted, but had not noticed any change. The sandy ridges, Mr. Browne informed me, continued as far as he went; and, to all appearance, for miles beyond. The day we returned to the creek was one of most overpowering heat, the thermometer at noon being 117 degrees in the shade. I had promised to wait for Mr. Browne at the shallow puddle, but the sun's rays fell with such intense effect on so exposed a spot that I was obliged to seek shelter at the creek. It blew furiously during the night of the 13th, in heated gusts from the north-east, and on the morning of the 14th the gale continued with unabated violence, and eventually became a hot wind. We were, therefore, unable to stir. The flies being in such myriads around us, so that we could do nothing. It is, indeed, impossible for me to describe the intolerable plague they were during the whole of that day from early dawn to sunset.
On the night of the 14th it rained a little. About 3 a.m. the wind blew round to the north-west, and at dawn we had a smart shower which cooled the air, reducing the temperature to something bearable. The sun rose amidst heavy clouds, by which his fiery beams were intercepted in their passage to the earth's surface. Before we quitted our ground I sent Flood up the creek, to trace it into the hills, an intention I was myself obliged to forego, being anxious to remain with the cart. The distance between the two creeks is about 26 miles, but, as I have already described the intervening country, it may not be necessary to notice it further. I was unable to take many back bearings, as the higher portions of the ranges were enveloped in mist. We reached the glen at half-past 5 p.m., and took up our old berth just at the gorge, preparatory to ascending the hills on the following day. Flood had already arrived there, and informed me that he had not followed the creek to where it issued from the ranges, but had approached very nearly, and could see the point from which it broke through them. That he had not found any surface water, but had tried the ground in many places, and always found water at two or three inches depth, and that where the water was the most abundant the feed was also the most plentiful.
As I had anticipated, we had heavy rain all night, and in the morning continual flying thunder-storms. We started, however, at eight, and, leaving the cart to push on for the rocky gully, Mr. Browne and I proceeded to ascend some of the higher peaks, which we had not had time to do in our advance. We accordingly turned into a narrow valley, in the middle of which was the bed of a rocky watercourse, and on either side of it were large clusters of the Clematis in full flower, that, mixed with low bushes of Jasmine, sent forth a most delicious perfume. After winding up this valley for about a mile and a half, we were stopped by a wall of rock right across it, and obliged to turn back. We were, however, more fortunate in our next attempt, and succeeded in gaining the summit of one of the loftiest hills on the range, on the very top of which we found large boulders of rocks, imbedded in the soil. They varied in size, from a foot in diameter to less, and were rounded by attrition, just like the rounded stones in the bed of a river, or on the sea shore. The hill itself was of schistose formation, the boulders of different kinds of rocks, and very sparingly scattered through the soil. We had scarcely reached the summit of this hill, when it was enveloped in thick clouds, from which the lightning flashed, and the thunder pealed close to us, and crack after crack reverberated along the valleys. It soon passed away, however, and left us well drenched, but the western horizon was still black with clouds. From this hill we proceeded to another, which at first sight I had thought was of volcanic origin, but proved to be like the first, of schistose formation, and was covered with low scrub. About 2 p.m. we had finished our work, and the sun shone out. On looking back towards the plains we now saw them flashing in the light of waters, and I regretted that we had been forced to retreat before the rains set in. However, seeing that the country was now in a fitter state to travel over, I determined on returning with all speed, to give Mr. Poole an opportunity to pass to the point where I had been, whilst I should move the party over the hills. We struck across the ranges, direct for the rocky gully, from the last hill we ascended, and rode past some very romantic scenery, but I had not time to make any sketch of it. Flood and Morgan had already arrived in the glen, and tethered out the horses in some long grass. At this place we were about 38 miles distant from the camp; but, as the cart could not travel so far in one day, I directed the men to bring it up, and on the morning of the 18th left them for the camp, with Mr. Browne, where we arrived at sunset. But little rain had fallen during the day, still it was easy to foretell that it had not ceased. The wind, for the last three days, had been blowing from the N.W., but on the 19th flew round to the S.E., and although no rain fell during the day, heavy clouds surrounded us. Considering, however, the rapidity of evaporation in such a climate, and the certainty that the rains would be followed by extreme heat, I was anxious that Mr. Poole should proceed on his journey without delay, he accordingly prepared to leave us on the 20th.
The reader will have inferred, from what I have said on the subject, that my object at this particular time was to attain the meridian of Mount Arden, as soon as circumstances should enable me. Had not this intention influenced me, on my recent journey, I should have kept nearer to the ranges; but I hoped, by taking a westerly course, that I should strike the N.E. angle of Lake Torrens, or find that I had altogether cleared it; added to this Mr. Eyre had informed me that he could not see the northern shore of that lake; I therefore thought that it might be connected with some more central body of water, the early discovery of which, in my progress to the N.W., would facilitate my future operations. This was a point whereon I was most anxious to obtain information; but, as my horses were knocked up, it appeared to me, that Mr. Poole, with fresh horses, would find no difficulty in gaining a distance sufficiently great to enable me to act on the knowledge he might acquire of the distant interior.
