reefs, Half-way Island, which is the southernmost of them, will be seen to the south-west; and here I would recommend the ship to anchor for the night. If this island can be passed, however, before three in the afternoon, and the sun do not obscure the sight, she may push on south-westward till an hour before sunset; and anchor under the lee of any of those sand banks which lie in the route, the ground being better here than in the eastern part of the Strait.
From Half-way Island, continue to follow the Investigator's track, steering S.W. to S.W. by W. by compass, as the small reefs and banks will allow; and here there is no necessity for a boat to be kept a-head. The flat top of one of the York Isles, called Mount Adolphus by captain Bligh, will be the first high land seen, and afterwards Mount Ernest; the cross bearings of which will show the situation on the chart, until the Double Isle, which makes as two small hummocks, comes in sight. Steer then for Double Isle, pass on the north side, and haul south-westward for Wednesday Island, which will be three leagues distant. Pass it also on the north side, about one mile, and the same by Hammond's Island, which lies next to it. There will be an extensive reef on the starbord hand, but the smallest distance between it and the islands is above two miles; and a W.S.W. course by compass, will lead fair through the passage, with soundings from 9 to 6 fathoms. Booby Isle will presently be seen a-head, appearing at first like a white sand bank; it may be passed within a mile or two on either side, and is the last of the dangers, if it can be classed under them, of Torres' Strait. A ship should afterwards steer, by compass, W. by S. thirty or forty miles; and the course may then be directed for any part of the world.
In case the approach of night, or any other circumstance should make it desirable, shelter may be had under the Prince of Wales' Islands, or under Booby Isle; and if a boat be sent on shore at dusk to Booby Isle, many birds, and perhaps some turtle may be procured.
This passage through Torres' Strait will occupy from three to five days, according to the freshness of the south-east trade, and the
