In the centre of this shoal are some dry rocks.
At the distance of nearly five miles from the above island is the rocky islet a, in latitude 10 degrees 36 minutes 50 seconds, and longitude 142 degrees 27 minutes 45 seconds; it is of small size, and surrounded by deep water; and, being easily seen from the strait between Cape York and the York Isles, serves to direct the course.
POSSESSION ISLES consist of nine or ten islets, of which 2 and 7 only are of large size, and neither of these are two miles long; they are also higher than the others.

Number 1 is a small conical hill; 2 is hummocky; 3, 4, and 6, are very small; 5 makes with a hollow in its centre, like the seat of a saddle.

The passage between 2 and the small islets 3 and 4 is the best; there is six and seven fathoms water; but in passing this, it must be recollected that the tide sets towards the islands on the northern side.
ENDEAVOUR STRAIT is on the south side of Prince of Wales' Islands: a shoal extends from Cape Cornwall (latitude 10 degrees 45 minutes 45 seconds, longitude 142 degrees 8 minutes 35 seconds) to the westward, and is probably connected with a strip of sand that stretches from Wallis' Isles to Shoal Cape.

We crossed it with the cape bearing about East, when the least depth was four fathoms; but on many parts there are not more than three fathoms.

Variation 5 degrees 38 minutes West.
PRINCE OF WALES ISLANDS are much intersected by straits and openings, that are very little known; there was an appearance of a good port, a little to the South-West of HORNED HILL (latitude 10 degrees 36 minutes 35 seconds, longitude 142 degrees 15 minutes) which may probably communicate with Wolf's Bay; the strait to the south of Wednesday Island also offers a good port in the eastern entrance of some rocky islands and without them is the rock b, with some sunken dangers near it.
WEDNESDAY ISLAND; its north end, in latitude 10 degrees 30 minutes 10 seconds, and longitude 142 degrees 15 minutes, may be approached close, but a considerable shoal stretches off its western side, the greater part of which is dry.
Off HAMMOND'S ISLAND is a high, conspicuous rock, bearing West 3/4 South, and five miles and three-quarters from the north end of Wednesday Island.
Captain Flinders passed through the strait separating Wednesday Island from Hammond's Islands, and had four, five, and six fathoms.
Abreast of the strait separating GOOD'S ISLAND from the latter is the reef c, on which are several dry rocks, but abreast of it, and one mile and one quarter from it, is the reef d,* which is generally covered; the latter bears South 75 degrees West three miles and a quarter from the rock off Hammond's Island, and about North 45 degrees West two and a quarter miles from the opening between Good and Hammond's Island; the marks for avoiding it are given in the sailing directions.
