seemed about thirty or forty miles distant; and a very indistinct blue
hill was seen to the W.N.W. To the northward, ranges rose beyond ranges,
and to the eastward, the country seemed to be flat, to a great extent,
and bounded by distant mountains. To the southward, the eye wandered over
an unbroken line of horizon, with the exception of one blue distant
elevation: this immense flat was one uninterrupted mass of forest without
the slightest break. Narrow bands of scrub approached the river from the
westward, and separated tracts of fine open forest country, amongst which
patches of the Poplar-gum forest were readily distinguished by the
brightness of their verdure. A river seemed to come from the south-west;
the Isaacs came from the north-west, and was joined by a large creek from
the northward. There was no smoke, no sign of water, no sign of the
neighbourhood of the sea coast;--but all was one immense sea of forest
and scrub.
The great outlines of the geology of this interesting country were seen
at one glance. Along the eastern edge of a basaltic table land, rose a
series of domitic cones, stretching from south-east to north-west,
parallel to the coast. The whole extent of country between the range and
the coast, seemed to be of sandstone, either horizontally stratified, or
dipping off the range; with the exception of some local disturbances,
where basalt had broken through it. Those isolated ranges, such as
Coxen's Range--the abruptness of which seemed to indicate igneous
origin--were entirely of sandstone. The various Porphyries, and Diorites,
and Granitic, and Sienitic rocks, which characterize large districts
along the eastern coast of Australia, were missing; not a pebble, except
of sandstone, was found in the numerous creeks and watercourses. Pieces
of silicified wood were frequent in the bed of the Isaacs.
The nature of the soil was easily distinguished by its vegetation: the
Bastard box, and Poplar gum grew on a stiff clay; the narrow-leaved
Ironbark, the Bloodwood, and the Moreton Bay ash on a lighter sandy soil,
which was frequently rotten and undermined with numerous holes of the
funnel ant. Noble trees of the flooded-gum grew along the banks of the
creeks, and around the hollows, depending rather upon moisture, than upon
the nature of the soil. Fine Casuarinas were occasionally met with along
the creeks; and the forest oak (Casuarina torulosa), together with
rusty-gum, were frequent on the s
