came to stones, triodia, and mallee, a low eucalyptus of the gumtree
family, growing generally in thick clumps from one root: its being
rooted close together makes it difficult travelling to force one's way
through. It grows about twenty feet high. The higher grade of
eucalypts or gum-trees delight in water and a good soil, and nearly
always line the banks of watercourses. The eucalypts of the mallee
species thrive in deserts and droughts, but contain water in their
roots which only the native inhabitants of the country can discover. A
white man would die of thirst while digging and fooling around trying
to get the water he might know was preserved by the tree, but not for
him; while an aboriginal, upon the other hand, coming to a
mallee-tree, after perhaps travelling miles through them without
noticing one, will suddenly make an exclamation, look at a tree, go
perhaps ten or twelve feet away, and begin to dig. In a foot or so he
comes upon a root, which he shakes upwards, gradually getting more and
more of it out of the ground, till he comes to the foot of the tree;
he then breaks it off, and has a root perhaps fifteen feet long--this,
by the way, is an extreme length. He breaks the root into sections
about a foot long, ties them into bundles, and stands them up on end
in a receptacle, when they drain out a quantity of beautifully sweet,
pure water. A very long root such as I have mentioned might give
nearly a bucketful of water; but woe to the white man who fancies he
can get water out of mallee. There are a few other trees of different
kinds that water is also got from, as I have known it obtained from
the mulga, acacia trees, and from some casuarina trees; it depends
upon the region they are in, as to what trees give the most if any
water, but it is an aboriginal art at any time or place to find it.

The mallee we found so dense that not a third of the horses could be
seen together, and with great difficulty we managed to reach the foot
