ll deeper interest attaches to those regions, now
that the rapid increase of the most industrious and, may we add most
deserving people on earth, suggests that the land there has been reserved
by the Almighty for their use.

In Australia, the great family of civilized man seems still at that early
period between history and fable, upon which, even in "the world as known
to the ancients," the Roman poet had to look very far back:--

"Communemque prius, ceu lumina solis et auras, Cautus humum longo
signavit limite mensor." [* Ovid, Met. lib. i.]

The Journey narrated in this work was undertaken for the extension of
arrangements depending on physical geography. It completes a series of
internal surveys, radiating from Sydney towards the west, the south, and
the north, which have occupied the author's chief attention during the
last twenty years; and, as on former occasions, it has enabled him to
bring under the notice of men of science some of the earth's productions
hitherto unknown. He cannot sufficiently express his sense of obligation
in this respect, to Mr. Bentham, Sir William Hooker, Dr. Lindley, and
Professor De Vriese, for supplying the botanical matter and notes
contained in this volume, and thus contributing to the general stock of
human knowledge. It is also his pleasing duty to state, that during the
long journey of upwards of a year, Captain P. P. King, R. N., kept a
register of the state of the barometer at the sea side; and, in the midst
of his important avocations, determined, by a very elaborate comparison
of minute details, all the heights of localities herein mentioned.

The new geographical matter is presented to the public with confidence in
its accuracy, derived as it is from careful and frequent observations of
latitude; trigonometrical surveying with the theodolite, whereever
heights were available; and, by actual measurement of the line of route.
This route was connected, at its commencement and termination, with the
trigonometrical survey of the colony; and, in closing on Mount Riddell, a
survey extending two degrees within the tropics, the near coincidence of
his intersections with that summit, as fixed by his survey of 1830, could
not but be very satisfactory to the author.

The geological specimens collected during this journey have been
deposited in the British Museum, and their original locality is shown on
the maps by the numbers marked upon the specimens, so that they may be
available
