"Vessels from Sydney bound to Coffin's Bay, should proceed as if bound to
Port Lincoln until arrived off the Neptune Islands, when they should
steer for Perforated Island, having passed which, steer for Point
Whidbey, giving it a berth of at least two miles. In running along shore
from Point Whidbey to Point Sir Isaac, come no nearer the shore than two
miles, until you get the latter point to bear east-south-east as the
rocks lay a long way from the shore. Having arrived at Point Sir Isaac
proceed as directed before.

"Althorp's Island is of moderate height, situated at the entrance of
Investigator's Straits; may be passed close to on the south side. Several
other islands and reefs lay between it and York's Peninsula, rendering
that passage highly dangerous.

"Wedge Island, one of the Gambier Group, may easily be known by its
wedge-like form, sloping from south-east to north-west. There are two
peaked rocks off the south-east end, one mile off shore, also a small
island, bearing west five miles from the south end, not laid down in
Flinders' charts.

"Thistle's Island, is low at each end but high in the middle, it lays in
a north-west and south-east direction. There are some rocks which lay off
the northern point about three miles, which being connected with the
island itself, forms a good anchorage behind, secure from all but north
and east winds, another good place for a fishing party. See Port Lincoln
directions.

"Neptune's Islands are low, three in number, and having numerous rocks
and reefs amongst them; ought not to be approached too closely, there
being generally a strong swell from the south-west, the sea breaks over
them with great violence.

"Liguanea Island is of moderate elevation, and may be passed on the south
side at a distance of two miles.

"Perforated Island, as its name imports, may be known by its having a
hole through it near the north end and close to the top of the island, it
may be passed close on any side. FOUR HUMMOCKS may easily be known from
their appearance answering to their name.

"Greenly Island, this is a peaked island, rather high, and may be seen
ten leagues off. There is another island laying south and by west, seven
miles, not laid down in Flinders', and two other reefs between them,
rendering the passage unsafe.

"Proceeding along shore to the northward you will fall in with Flinders'
Island. This is a large island, covered with wood, with plenty of
