ephen's Range which lies behind Collier's
Bay, and in the low ground near Glenelg River.

With the extent of Stephen's Range I am unacquainted; but I have no doubt
that the high land whence the Fitzroy River takes its rise is merely an
under-feature again thrown off from it, and which I propose to call
Wickham's Range after Captain Wickham, R.N., the discoverer of the
Fitzroy.

We may form some idea of the limits of Stephen's Range in a north and
east direction from the following passage extracted from Captain King's
survey of these coasts:*

Lacrosse Island is situated in the entrance of a deep opening trending to
the south-south-west towards some steep, rugged hills. The character of
the country is here entirely changed. Irregular ranges of detached rocky
hills of sandstone formation, very slightly clothed with small shrubs and
rising abruptly from extensive plains of low, level land, seem to have
superseded the low wooded coasts that almost uninterruptedly prevails
between this and Cape Wessel, a distance of more than six hundred miles!

(*Footnote. King's Australia volume 1 page 291.)

...

It appears therefore that this main range contains within it the sources
of Roe's River, Prince Regent's and Glenelg Rivers, most probably the
Fitzroy, and those that run into Cambridge Gulf and perhaps others that
have their embouchures between this last and Admiralty Gulf.

From an accident having occurred to the only barometer we could carry
with us I am unable to state the elevation of the highest land we reached
above the level of the sea; but the appearance of the country on the
coast does not give the impression of any very elevated ground existing
near it. This however is owing to the great height of the shore cliffs
and the gradual rise of the land towards the interior. The following
observations, made with the barometer before it was broken, will show
however that the altitude of the country at no great distance from the
coast is considerable.

MACDONALD'S RANGE.

Our first encampment was on the banks of a small river at a spot 2,640
feet from the sea. This river ran through a deep and narrow valley,
descending with a nearly regular slope from a tableland of sandstone, in
which it took its rise about seven miles inland. At this encampment the
height of the bed of the river above the level of the sea was 188.76
feet, as found by the mean of several very accordant observations, which,
at the same average slope,
