About two o'clock, P.M. we passed a little grass, and as the day appeared likely to become rainy, I halted for the night. Leaving the native boy to hobble the horses, I took my gun and ascended one of the hills near me for a view. Lake Torrens was visible to the west, and Mount Deception to the N.W. but higher hills near me, shut out the view in every other direction. In descending, I followed a little rocky gully leading to the main watercourse, and to my surprise and joy, discovered a small but deep pool of water in a hole of the rock: upon sounding the depth, I found it would last us some time, and that I might safely bring on my party thus far, until I could look for some other point for a depot still farther north; the little channel where the water was, I named Depot Pool.
Regaining the camp, I immediately set to work with the native boy to construct a bough hut, as the weather looked very threatening. We had hardly completed it before the rain came down in torrents, and water was soon laying every where in the ledges of rock in the bed of the watercourse. So little do we know what is before us, and so short a time is necessary to change the aspect of affairs, and frequently too, when we least expect it!
July 14.—Our hut not having been quite water-tight before the rain came, we got very wet during the night, and turned out early this morning to go and hunt for firewood to warm ourselves.
As the weather still continued rainy, I determined to give our horses a day's rest, whilst I walked up the watercourse to examine it farther. I found the hills open a good deal more as I proceeded, with nice grassy valleys between; and the hills themselves, though high and steep, were rounded at the summits, and richly clothed with vegetation: among them numerous watercourses took their rise in the gorges, and generally these were well marked by gum-trees. Altogether it was a pretty and fertile spot, and though very hilly, would do well for stock, if permanent water could be found near. I was quite unsuccessful, however, in my search for this, and the native boy, whom I sent in the opposite direction, after my return, was equally unfortunate. Towards evening, one of the horses having broken his hobbles, and got alarmed, galloped off, taking the other with him. Tired and wet as I was, I was obliged to go after them, and it was some miles from the camp, before I could overtake and turn them back. Our latitude was 30 degrees 55 minutes S.
July 15.—This morning was misty and clondy, and dreadfully cold. We set off early and commenced tracing up and examining as many of the watercourses as we could; we did not, however, find permanent water.
Under one low ridge we met with what I took to be a small spring emanating from a limestone rock; but it was so small as to be quite useless to a party like mine, though the natives appeared frequently to have resorted to it. Finding the courses of the main channel become lost in its many branches, I ascended the dividing ridge, and crossed into the bed of another large watercourse, in which, after travelling but a short distance, I found a fine spring of running water among some very broken and precipitous ranges, which rose almost perpendicularly from the channel; in the latter, high ledges of a slaty rock stretched occasionally quite across its bed, making it both difficult and dangerous to get our horses along. In the vicinity of the water the grass was tolerably good, but the declivities upon which it principally grew, were steep and very stony.
Having hobbled the horses, I took my gun, and walked down the watercourse, to a place where it forms a junction with a larger one, but in neither could I find any more water. Upon my return, I found that the native boy had caught an opossum in one of the trees near, which proved a valuable addition to our scanty and unvaried fare. The latitude to-day was 30 degrees 51 minutes S.
July 16.—Tracing down the watercourse we were encamped on, to the junction before mentioned, I steered a little more to the north, to ascend a high stony range, from which I hoped to obtain a view to the eastward; but after considerable toil in climbing, and dragging our horses over loose rolling stones, which put them constantly in danger of falling back, I was not rewarded for the trouble I had taken: the view to the east was quite shut out by high rugged ranges of ironstone and quartz, whilst to the north, the hills appeared lower and more open.
It now became a matter of serious consideration, whether I should pursue my researches any farther at present. I was already about 120 miles away from my party, with barely provisions enough to last me back; and the country, in advance, appeared to be getting daily more difficult; added to this, the "WATERWITCH" was waiting at the head of Spencer's Gulf for my return.
After reflecting on my position, I decided to rejoin my party without delay; and descending the range to the S. E., I steered for a large watercourse we had crossed in the morning; intending to trace it up, for the purpose of examining its branches. The bed of this watercourse, at first, was very wide, and lined with gum-trees; but as I advanced, I found its channel became contracted, and very rocky, the gum-trees disappearing, and giving place to the salt-water tea-tree. By nightfall, I was unable to proceed any further, owing to the large stones and rocks that interposed themselves. Retracing my steps, therefore, for a mile or two, to a little grass I had observed as I passed by, I bivouacked for the night, being, as well as the horses, quite knocked up. The native boy, who accompanied me, was equally fatigued; and we were both lame from walking across so rugged a country, over a great portion of which we found it quite impracticable to ride. Our stage could not have been less than twenty-five or twenty-six miles during the day, yet we had not met with a drop of water, even though we had high ranges, large watercourses, and huge gum-trees on every side of us. As usual, the traces of high floods were numerous; and the channels of these watercourses, confined as they are by precipitous ranges, must, at times, be filled by rapid and overwhelming torrents, which would collect there after heavy rains.
