s not quite a degree of latitude, the coast is
formed of a range of hills, of uniform and moderate elevation. From
Geographer's Bay to the northward of Swan River, the whole coast line
is a limestone ridge, varying in height from twenty to six hundred
feet, and extending inward to the distance of from one to five miles.
Behind this ridge (whose occasional naked and barren appearance
Captain Stirling also thinks may have caused the early and continued
prejudice against the fertility of this western coast) commences a
great plain, which occupies a space, from south to north, of
undetermined length, (reaching, perhaps, to King George's Sound,) and
varying, in breadth, from twenty to fifty miles. The eastern boundary
of this plain skirts the base of an almost continuous and abrupt chain
of mountains, to which Captain Stirling gave the name of "General
Darling's Range." One of the points, the highest seen and measured by
him, was about three thousand feet high, The average height is stated
to be from twelve hundred to fifteen hundred feet. The base is
granite; the sides, in many parts, naked; and the soil supports but
little vegetation, except the Stringy-bark and some hardy plants.

Captain Stirling observes, that coal was not found, because it was not
particularly sought for; but he is of opinion that the general
character of the country is such as to warrant the belief that it
might be found; "for," he observes, "all the concomitant strata or
members of the coal formation are exposed on different parts of the
surface, below which I had no opportunity to explore. Indeed, the
carboniferous order of locks is that which is most frequently
exhibited throughout this territory; and I have no doubt important
results would arise from a proper examination into its mineralogical
resources."

With reference to a supply of fresh water, so indispensably necessary
in every settled country, the researches made by Captain Stirling and
Mr. Fraser were attended with the most satisfactory results. The
former observes, that the clouds which are impelled against the
western side of the range of mountains are condensed into rain, the
water of which is conducted across the plain to the sea, in numerous
streams, but chiefly by three principal rivers, terminating in
estuaries, or salt-water lakes. These are--the Swan River, opposite
the Island Rottenest; the Riviere Vasse, and Port Leschenault, in
Geographer's Bay. "We found," says Captain Stirl
