sandhill country, covered with desert vegetation, surrounded it on all
sides. Nearer to us, north-westerly, and stretching nearly to west,
lay the dry, irregular, and broken expanse of an ancient lake bed. On
riding over to it we found it very undefined, as patches of sandhills
occurred amongst low ridges of limestone, with bushes and a few low
trees all over the expanse. There were patches of dry, soda-like
particles, and the soil generally was a loose dust coloured earth.
Samphire bushes also grew in patches upon it, and some patches of our
arch-enemy, triodia. Great numbers of wallaby, a different kind from
the rock, were seen amongst the limestone rises; they had completely
honeycombed all we inspected. Water there was none, and if Noah's
deluge visited this place it could be conveniently stowed away, and
put out of sight in a quarter of an hour.

Returning to the horses, we turned southerly to the most westerly
creek that issues from the range. I found some water up at the head of
it in rock-holes; but it was so far up easterly, that we could not
have been more than five or six miles across the hills from our last
night's encampment at the Circus. There was only a poor supply of
water in two small holes, which could not last longer than three days
at the most. The thermometer ranged up to 104 degrees to-day. Some of
the horses are now terribly footsore. I would shoe them, only that we
are likely to be in the sandhills again immediately. I did not exactly
know which way to go. Mr. Tietkens and I ascended the highest hill in
this part of the range. I had yesterday seen something like the top of
a ridge south-westerly; I now found it was part of a low distant
range, and not of a very promising nature. There was a conspicuous
mountain, which now bore north-east about fifty miles away, and I
fancied I saw the refracted tops of other ranges floating in the
mirage. I thought, from the mountain just mentioned, I might discover
