In general the inlets of this coast form extensive ports at their entrance; and, when they begin to assume the character of a river, their course becomes tortuous, and very irregular; of which there cannot be a better instance than the neighbouring river, Roe's River.

Prince Regent's River trends into the interior in a South-East by East direction for fifty-four miles.

With scarcely a point to intercept the view, after being thirteen miles within it.

The entrance is formed by Cape Wellington on the east, and High Bluff on the west, a width of eight miles, but is so much contracted by islands, that, in hauling round Cape Wellington, the width is suddenly reduced to little more than a mile: at the branching off of Rothsay Water, it is little more than half a mile, and also the same width at the entrance of St.
George's Basin.

In this space, however, it is in some parts a little wider, but in no part between projecting points is it more than one mile and a quarter.
