The general character of the banks, which are lofty and abrupt, is precisely the same with that of the rivers falling into York Sound; and the level of the country does not appear to be higher in the interior than near the coast.

The banks are from two to four hundred feet in height, and consist of close-grained siliceous sandstone, of a reddish hue;* and the view (Plate above) shows that the beds are nearly horizontal, and very regularly disposed; the cascade there represented being about one hundred and sixty feet in height, and the beds from six to twelve feet in thickness.

Two conspicuous hills, which Captain King has named Mounts Trafalgar and Waterloo, on the north-east of Prince-Regent's River, not far from its entrance, are remarkable for cap-like summits, much resembling those which characterize the trap formation.

(Sketch 3.) (*Footnote.

Narrative 1 and 2.) The coast on the south of this remarkable river, to Cape Leveque, has not yet been thoroughly examined; but it appears from Captain King's Chart (Number 5) to be intersected by several inlets of considerable size, to trace which to their termination is still a point of great interest in the physical geography of New Holland.
