On trying the thermometers, one on Lewis’s Hill, and the other on the Black Hill, I found that they boiled at 209 degrees and 208 degrees respectively.
On the 26th Jones was unfortunate enough to snap the pole of his dray, and I was consequently detained on the 27th repairing it. I was the more vexed at the accident, being anxious to push over the ranges and gain the plains, in order to prevent Mr. Poole the necessity of re-ascending them. I felt satisfied that I should find a sufficiency both of water and feed at the gorge of the Rocky Glen, to enable me to rest until more thorough knowledge of the country could be gained, whilst by encamping at that place I should save Mr. Poole a journey of 63 miles.
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.
