The land on the western side of the gulf is high and rocky; but the opposite shore is very low, and apparently marshy.

The bottom is of sand, as are the banks on either side, and affords good anchorage: the tide stream runs with great strength in mid-channel, but is easily avoided by anchoring upon the weather shore near the edge of the bank.
The channels on either side of Adolphus Island are called the East and West Arms.

The East Arm is from one to two miles and a half wide, and four or five fathoms deep.

At ten miles it is joined by an arm that washes the south side of Adolphus Island, and the united streams trend together in a South-East direction, under the foot of Mount Connexion, for a considerable distance.

This inlet was not examined.
