t about
North West by North, which will take you inside the covered reef z. Your
course then must be round the Albany Islands, and hence North West by
North for a, which is a rocky islet that may be seen from abreast the
Albany Isles.

The passage through the Possession Isles and Endeavour Strait is not to
be recommended for a large ship, on account of the shoal water that
extends from Wallis' Isles towards Shoal Cape; but the route round the
north end of Wednesday and Hammond's Islands is preferable. Upon passing
reef a, Wednesday Island will be seen: in steering towards it, avoid
standing too close to the rocky islet that is abreast of the strait
between it and Horned Hill, as some sunken rocks stretch off it for about
a quarter of a mile: steer round the north point of Wednesday Island at
half a mile, and then West by South 1/4 South which will carry you to the
northward of the rock off Hammond's Island. Having passed this rock,
steer South-West by West; and when abreast of the south-west end of
Hammond's Island, haul towards a reef, to the southward of the course, on
which you will see some dry rocks, which you may pass within half a mile
of: you will then avoid reef d, which is generally, if not always,
covered: the fairway of this channel is seven and eight fathoms deep.

When the summit of Good's Island bears South-West by West, steer West by
South southerly for Booby Island, by which you will avoid Larpent's bank,
and when you have passed it, you are clear of the strait. Hence you may
steer West 3/4 South through the night, on which course you will very
gradually deepen your water.
