he had visited many of the located parts of New South Wales, Port
Phillip, South Australia, Western Australia, and Van Diemen's Land. In
the years 1836, 1837, 1838, 1839, and 1840 he had conducted expeditions
across from Liverpool Plains in New South Wales to the county of Murray,
from Sydney to Port Phillip, from Port Phillip to Adelaide, and from King
George's Sound to Swan River, besides undertaking several explorations
towards the interior, both from Port Lincoln and from Adelaide.

To the knowledge and experience which were thus acquired, the author must
ascribe the confidence and good opinion of his fellow-colonists, which
led them in 1840 to place under his command an undertaking of such
importance, interest, and responsibility; and to these advantages he
feels that he is in a great measure indebted, under God's blessing, for
having been enabled successfully to struggle through the difficulties and
dangers which beset him, in crossing from Adelaide to King George's
Sound.

With this explanation for obtruding upon the public, the author would
also solicit their indulgence, for the manner in which the task has been
performed. The only merit to which he can lay claim, is that of having
faithfully described what he saw, and the impressions which were produced
upon him at the time. In other respects it is feared that a work, which
was entirely (and consequently very hastily) prepared for the press from
the original notes, whilst voyaging from Australia to England, must
necessarily be crude and imperfect. Where the principal object, however,
was rather to record with accuracy than indulge in theory or conjecture,
and where a simple statement of occurrences has been more attended to
than the language in which they are narrated, plainness and fidelity
will, it is hoped, be considered as some compensation for the absence of
the embellishments of a more finished style, or a studied composition,
