In the entrance is Muiron Island, and two others, h and i; and within the gulf they are too numerous to distinguish: all the outer ones have been assigned correct positions to, as have all between Exmouth Gulf and Dampier's Archipelago.

The islets y and z are the outer ones of the group; between which and the western shore there is a space of fourteen miles in extent, quite free from danger, with regular soundings between nine and twelve fathoms on a sandy bottom.

Under the western shore, which is the deepest, there are some bays which will afford anchorage; but the bottom is generally very rocky.
In the neighbourhood of the Bay of Rest, the shore is more sinuous, and in the bay there is good anchorage in three and four fathoms, mud.

Here the gulf is twelve miles across, and from three to six fathoms deep; but the eastern side is shoal and very low.

The gulf then shoalens and narrows very much; and at fifteen miles farther terminates in an inlet, or, as has been subsequently conjectured, a strait communicating with the sea at the south end of the high land that forms the western side of the gulf, and which is doubtless the identical Cloates Island that has puzzled navigators for the last eighty years.
