To the southward of this there are several shoal bays.

To the eastward of Cape Ransonnet, which is peaked and of a moderate elevation, there are several little creeks well adapted for boats and, to the westward, a sandy plain extends to the south extremity of the island.

That part of Shark's Bay, between Dirk Hartog's Island and Peron's Peninsula, is formed by Le Passage Epineux, Useless Harbour (Havre Inutile) and Henry Freycinet's Harbour: to the southward of the line of bearing between Quoin Point and Cape Lesueur, the sea is shoal and studded with banks, but to the north it is quite open.
The Passage Epineux, which separates Dirk Hartog's Island from the main, is about two miles wide; but the reefs and rocks, which protrude from either shore, reduce the passage to half that width.

The depth upon the rocky bar which stretches across the entrance is six fathoms, but immediately without it the depth is twenty-two fathoms.

M.De Freycinet says, that a ship upon a lee shore in the vicinity of Point Escarpee may enter this opening with confidence; she will find a good shelter and excellent anchorage in five and six fathoms fine sand.
