as impregnated with ammonia from the excreta of
emus, dogs, birds, beasts, and fishes, but the horses drank it with
avidity. Above this we got some sweet water in rocks and sand. I
called the queer-looking wall the Ruined Rampart. There was a quantity
of different kinds of water, some tasting of ammonia, some saltish,
and some putrid. A few ducks flew up from these strange ponds. There
was an overhanging ledge and cave, which gave us a good shade while we
remained here, the morning being very hot. I called these MacBain's*
Springs.

Following the creek, we found in a few miles that it took its rise in
a mass of broken table-lands to the south. We still had the high walls
of the Petermann to the north, and very close to us. In five miles we
left this water-shed, and descended the rough bed of another creek
running eastwards; it also had some very queer water in it--there were
pink, green, and blue holes. Ducks were also here; but as we had no
gun, we could not get any. Some sweet water was procured by scratching
in the sand. This creek traversed a fine piece of open grassy
country--a very park-like piece of scenery; the creek joined another,
which we reached in two or three miles. The new creek was of enormous
width; it came from the low hills to the south and ran north, where
the Petermann parted to admit of its passage. The natives were burning
the country through the pass. Where on earth can it go? No doubt water
exists in plenty at its head, and very likely where the natives are
also; but there was none where we struck it. I called this the Hull*.

The main range now ran on in more disconnected portions than formerly;
their general direction was 25 degrees south of east. We still had a
mass of low hills to the south. We continued to travel under the lea
of the main walls, and had to encamp without water, having travelled
twenty-five miles from the Ruined Rampart. A high cone in the range I
called Mount Curdie*. The next morning I ascended the eastern end of
Mount Curdie. A long way off, over the tops of other hills, I could
see a peak bearing 27 degrees south of east; this I supposed was, as
it ought to be, the Sugar-loaf Hill, south westward from Mount Olga,
and mentioned previously. To the north there was a long wall-like line
stretching across the horizon, ending about north-east; this appeared
to be a disconnected range, apparently of the same kind as this, and
having gaps or passes to allow watercourses to run
