High water at full and change takes place at: The anchorage off Vansittart Bay at 9 hours 15 minutes.
In Montagu Sound at 12 hours 00 minutes.
In Careening Bay at 12 hours 00 minutes.
In Prince Regent's River at 12 hours 20 minutes.
The rise of the tide, to the westward of Cape Van Diemen, and particularly to the westward of Cape Bougainville, appeared gradually to increase: the greatest that we experienced was in the vicinity of Buccaneer's Archipelago; and at the anchorage in Camden Bay the tide rose thirty-seven feet; occasioned probably by the intersected nature of the coast.
The variation in this interval is almost too trifling to be noticed for the purposes of common navigation.

Between Capes Londonderry and Van Diemen it varies between 1/4 and 1 degree East.

Between the former and Careening Bay it was between 1 and 1 1/2 degrees East; at Careening Bay the mean of the observations gave 3/4 of a degree West; but to the westward of that, as far as Cape Villaret, the results of the observations varied between 1 degree East and 1 degree West.

Near the North-west Cape, and to the eastward of it as far as Depuch Island, it is about two degrees Westerly.
On the south-side of Clarence Strait the land is low, like the coast to the eastward.

PATERSON BAY appeared to be the mouth of a river, but it was not examined.
