When you have opened the inlet, steer in, and, having passed the inner cape, haul in to a sandy bay on the eastern side, where you may anchor in eight or nine fathoms at pleasure.
The centre of the shoal in the middle of the port bears North 1/4 East by compass, from the high round island, and North by West 1/4 West when in a line with Entrance Island.
High water appears to take place half an hour later than at Entrance Island, or about 10 hours 40 minutes after the moon's southing (the moon's age being thirteen days).

The tide did not rise more than six feet, but it wanted three days to the springs.

Captain Flinders supposes the spring tides to rise not less than fifteen feet.

The variation of the compass was 9 degrees 5 minutes East, off Cape Clinton, but at Entrance Island, according to Captain Flinders, it was 7 degrees 40 minutes East.
NORTHUMBERLAND ISLANDS.

In the direction of North 8 degrees East (magnetic) and five miles and a half from the 3rd Island, is a low rock which, at high water, is very little above the surface of the sea; it is very dangerous because it is in the direct track of vessels steering towards the Percy Isles.
