so much nearer relief. Every dry
hole gives a greater chance that the next will be full.

Near one hole we came on a ceremonial or dancing ground--that is, a
cleared space in the mulga scrub, circular in shape, with a cleanly swept
floor, trodden down by many feet. In the centre stood a sort of altar of
branches and twigs. It was evident that the blacks had danced round and
round this, though for what purpose I cannot say.

As the sun set our faith was rewarded; before us in an outcrop surrounded
by mulga lay two fine rock-holes with an ample supply. What a blessed
relief! In a few minutes the horses were gorged, and hard at work on the
rough grass near the holes. Hardy horses, indeed! Eight days from drink
to drink (not counting what we gave them), and hardly a scrap of feed.

We took a two days' rest for the sake of the grass, and varied our daily
fare of salt beef with small, tufted pigeons, which came in large numbers
to drink. We shot nearly one hundred of them, and ate boiled pigeon three
times a day with the voracity of black-fellows. Nor was Devil-devil
forgotten in the feast; he had become an expert rider, and had a far
better time than poor Val.

The curious fact of some rock-holes being full, whilst others a few miles
off are empty, again exemplifies the very local character of such rain as
visits these parts. The "Deep rock-holes," as we called them (in lat. 24
degrees 20 minutes, long. 127 degrees 20 minutes), are peculiar, for one
is perfectly cylindrical, two feet six inches in diameter going down
vertically to a depth of twenty feet; the other goes down straight for
six feet, and then shelves away under the rock to a depth of at least
twelve feet. It will be seen from our last few days' experience, and from
that of the few days soon to follow, that in this region rock-holes are
numerous. They are invariably situated on low surface outcrops of 'desert
sandstone, surrounded by mulga and grass; beyond that, sand. I take it
that they have been formed in the same way as the granite rock-holes in
the south of the Colony--that is, by decay; that the whole country has
been covered by a deposit of sand, borne by the winds, filling in former
valleys and hollows, leaving only occasional patches of rock still
visible. Their frequent occurrence would then be accounted for by the
fact that the deposit of sand is shallower here than elsewhere. That it
is so is pretty evident, for here the sand-ridges are much lower t
