Lower part of the Rocky Glen
As we descended from the ranges I observed that all the water I had seen glittering on the plains had disappeared; I found too that the larger water-hole in the glen had rather fallen than increased during the rains. The fact however was, that the under-drainage had not yet reached the lower part of the gully.
We were now about 24 miles from the second creek Mr. Browne and I had crossed on our recent excursion, and from Flood's examination of it afterwards, I felt assured that unless a party was sent forward to dig a large hole for the cattle I could not prudently advance any farther for the present; but being anxious to push on, and hoping that the late rains had increased the supply of water in the creek, I sent Flood on the 28th with two of the men (Joseph and Sullivan) to dig a tank in the most favourable spot he could select, and followed him with the drays on the 29th. Wishing however to examine the country a little to the westward, I desired the men to keep on the plains about two miles from the foot of the ranges, until they should strike the creek or Flood should join them, and did not reach the encampment before eight o'clock.
Flood then told me that he had been to the place where he had before found most surface water; but that, notwithstanding the rains, it was all gone. He had tried the creek downwards, and had at length sunk a tank opposite to a little gully, thinking that it might influence the drainage. The tank was quite full, and continued so for two or three days after, when, without any great call upon it from the cattle, it sensibly diminished, and at length dried up, and we should have been obliged to fall back, if in tracing up the little gully we had not found a pond that enabled us to keep our ground. It often happened that we thus procured water in detached localities when there was not a drop in the main channels of the creeks. At this place the boiling point of the thermometer was 212 degrees; thus bringing us again pretty nearly on a level with the ocean, although we were at the time distant from it more than 480 miles.
At this period we had frequent heavy winds, with a heated temperature: yet our animals, if I except the dogs, did not suffer much. The sheep, it is true, would sometimes refuse to stir, and assemble in the shade, when on the march, whilst the dogs took shelter in wambut holes, and poking their heads out, would bark at their charge to very little purpose. It was evident, indeed, that the heat was fast increasing, and what we had already experienced was only an earnest of that which was to follow.
Mr. Poole had now been absent thirteen days, and I began to be anxious for his return. Our march to the second creek had again shortened his homeward journey 70 miles, and as I felt assured he would cross the creek at the point where we had dug the well, I stuck a pole up in it, with instructions, and on the 2nd December he rode into the camp with Mr. Browne, both much fatigued, as well as their horses. I had been engaged the greater part of the day fixing the points for another base line, as I was fearful that the angles of our first were too acute, and found that the party had got back on my return to the camp.
Mr. Poole informed me that as soon as the weather cleared, after leaving me on the range, he had pushed on. That on the 24th he left my cart tracks as they turned to the N.W., and continued the N.N.W. course as I had directed. On that day he encamped early at a good water-hole, as the horses had travelled fast; the country thereabouts had become more open, but water was exceedingly scarce. On this day he ascended a small sandstone hill, from which some high peaks on the range bore S.S.E.
On the 26th he had not advanced 10 miles, when the pack-horse fell exhausted by heat. Mr. Poole then consulted with Mr. Browne, and it was thought better by both to travel at night, and they accordingly did so. The country by moonlight appeared more open, and the water seemed to be in greater abundance, as if much more rain had fallen thereabouts than to the south. They continued a N.N.W. course until daylight, when they halted, and Mr. Browne ascended a sand hill, from whence he saw peaks on the range bearing to the north of east, and the Mount Serle range, bearing due west, distant 50 miles. The latter circumstance induced Mr. Poole, when he again resumed his journey, to change his course to west, in the hope that as he had passed the 30th parallel he should find Lake Torrens between himself and the ranges. Accordingly, on starting at 4 p.m. they went on that course, and halted at dawn on a swampy flat, under a gum-tree. Mr. Poole subsequently ascertained that the swamp was the head of a little creek falling into the Sandy Lake, where he afterwards terminated his journey.
The country had now assumed a very barren appearance. At sunrise Mr. Poole and Mr. Browne ascended another sand hill, from whence they again saw the hills to the westward, seemingly very high and steep; but there was no sign of an intermediate basin, the country towards the ranges bearing a most sterile aspect. Here Mr. Browne saw a new pigeon, which had a very singular flight.
