Exploration of Australia,' vol. i. p. 127:

"It was on this range (Lat. 26 degrees, 42') that Mitchell saw
the bottle-tree for the first time. It grew like an enormous
pear-shaped turnip, with only a small portion of the root in
the ground."

"A `Kurrajong.' The `Bottle-tree' of N.E. Australia, and also
called `Gouty-stem,' on account of the extraordinary shape of
the trunk. It is the `Binkey' of the aboriginals.

"The stem abounds in a mucilaginous substance resembling pure
tragacanth, which is wholesome and nutritious, and is said to
be used as an article of food by the aborigines in cases of
extreme need. A similar clear jelly is obtainable by pouring
boiling water on chips of the wood."

"A boundary-rider is not a `boss' in the Bush, but he is an
important personage in his way. He sees that the sheep in his
paddock draw to the water, that there is water for them to draw
to, and that the fences and gates are in order. He is paid
fairly, and has a fine, free, solitary life."
