The western entrance is about two miles and a half wide, and is deepest near the island: but, at a mile from the shore, we had no bottom with fourteen and seventeen fathoms.

The reefs project from Cape Dussejour for nearly three miles.

On the eastern side of Lacrosse Island, within half a mile of the point, we had seven fathoms, and there was every appearance of the channel being deep in the neighbourhood of Cape Domett.

Shakspeare Hill, the situation of which is in latitude 14 degrees 47 minutes 55 seconds, and longitude 128 degrees 24 minutes, is a conspicuous object on this promontory: it is high and rocky, and, at a distance, has the appearance of being insulated, like Lacrosse Island.
Having entered the gulf, it trends to the South-South-West for twenty-three miles to Adolphus Island, where it is divided into two arms, of which the westernmost is the principal.

At ten miles from Lacrosse Island, the channel is narrowed by shoals to a width of five miles, the shores being twelve miles apart.
