bounded to the west by St. Vincent's Gulf, and to
the east by the lake Alexandrina, and the sandy track separating that
basin from the sea. Supposing a line to be drawn from the parallel of
34 degrees 40 minutes to the eastward, it will strike the Murray river
about 25 miles above the head of the lake, and will clear the ranges,
of which Mount Lofty and Mount Barker are the respective terminations.
This line will cut off a space whose greatest breadth will be 55 miles,
whose length from north to south will be 75, and whose surface exceeds
7 millions of acres; from which if we deduct 2 millions for the
unavailable hills, we shall have 5 millions of acres of land, of rich
soil, upon which no scrub exists, and whose most distant points are
accessible, through a level country on the one hand, and by water on
the other. The southern extremity of the ranges can be turned by that
valley through which Mr. Kent returned to the schooner, after Captain
Barker's death. It is certain, therefore, that this valley not only
secures so grand a point, but also presents a level line of
communication from the small bay immediately to the north of the cape,
to the rocky point of Encounter Bay, at both of which places there is
safe anchorage at different periods of the year.

HINTS FOR FUTURE EXPEDITIONS.

The only objection that can be raised to the occupation of this spot,
is the want of an available harbour. Yet it admits of great doubt
whether the contiguity of Kangaroo Island to Cape Jervis, (serving as
it does to break the force of the prevailing winds, as also of the
heavy swell that would otherwise roll direct into the bay,) and the
fact of its possessing a safe and commodious harbour, certainly at an
available distance, does not in a great measure remove the objection.
Certain it is that no port, with the exception of that on the shores of
which the capital of Australia is situated, offers half the convenience
of this, although it be detached between three and four leagues from
the main.

On the other hand it would appear, that there is no place from which at
any time the survey of the more central parts of the continent could be
so effectually carried on; for in a country like Australia, where the
chief obstacle to be apprehended in travelling is the want of water,
the facilities afforded by the Murray and its tributaries, are
indisputable; and I have little doubt that the very centre of the
continent might be gained by a judic
