The channels between them appeared to be clear and free from hidden danger.

The depth among the islands is from ten to fifteen fathoms on a muddy bottom; but the anchorage is better between Kater Island and the promontory that separates it from Walmesly Bay, than any other part.

It is a very fine port, particularly near the bottom, in SWIFT'S BAY, where the depth is from four to five fathoms at low water, It is high water at full and change in Swift's Bay at twelve o'clock, which is two hours and a quarter later than in Vansittart Bay: the tide rose eighteen feet, whereas in Port Warrender its rise was only six.

The islands off the north-east end of Bigge's Island are more numerous than in other parts of the sound: they were only seen at a distance, and too numerous to give correct positions to.

BIGGE'S ISLAND is fourteen miles long, and from six to seven broad; it is of moderate height, and rocky character: its south end appeared to be thickly wooded.
