atch of white clay soil, glistening in the moon's
rays, and upon this there appeared an astonishing object--something
like the wall of an old house or a ruined chimney. On arriving, we saw
that it was a circular wall or dam of clay, nearly five feet high,
with a segment open to the south to admit and retain the rain-water
that occasionally flows over the flat into this artificial receptacle.

In spite of old Jimmy's asseverations, there was only sufficient water
to last one or two days, and what there was, was very thick and
whitish-coloured. The six animals being excessively thirsty, the
volume of the fluid gradually diminished in the moonlight before our
eyes; the camels and horses' legs and noses were all pushing against
one another while they drank.

This wall, or dam, constructed by the aboriginals, is the first piece
of work of art or usefulness that I had ever seen in all my travels in
Australia; and if I had only heard of it, I should seriously have
reflected upon the credibility of my informant, because no attempts of
skill, or ingenuity, on the part of Australian natives, applied to
building, or the storage of water, have previously been met with, and
I was very much astonished at beholding one now. This piece of work
was two feet thick on the top of the wall, twenty yards in the length
of its sweep, and at the bottom, where the water lodged, the
embankment was nearly five feet thick. The clay of which this dam was
composed had been dug out of the hole in which the water lay, with
small native wooden shovels, and piled up to its present dimensions.

Immediately around this singular monument of native industry, there
are a few hundred acres of very pretty country, beautifully grassed
and ornamented with a few mulga (acacia) trees, standing picturesquely
apart. The spot lies in a basin or hollow, and is surrounded in all
directions by scrubs and rolling sandhills. How we got to it I can
scarcely tell, as our guide kept constantly changing his course, so
that the compass was of little or no use, and it was only by the
sextant I could discover our whereabouts; by it I found we had come
fifty-eight miles from Youldeh on a bearing of south 68 degrees east,
we being now in latitude 30 degrees 43' and longitude 132 degrees 44'.
There was so little water here that I was unable to remain more than
one day, during which the thermometer indicated 104 degrees in the
shade.

To the eastward of this dam there was a sandh
