If the moon is up the islets will be readily distinguished, but otherwise it would be more prudent to wait for daylight. This course will carry a ship over two of my tracks, and the soundings will be in seventeen, eighteen, and nineteen fathoms. From the low isles direct your course for the Hope Islands, which bear from the former North 18 degrees West thirty-eight miles, but the course had better be within that line, to avoid some reefs in latitude 15 degrees 51 minutes: pass, therefore, within five miles of Cape Tribulation, when a direct course may be steered either to the eastward or westward of the Hope Isles. The better route will be within the western Hope, and along its reef at the distance of three-quarters of a mile, by which you will avoid reef a. When you are abreast of its north end, steer North by West westerly for twenty-eight miles; this will carry you to Cape Bedford which you may round at from one to three or four miles. You will see in your way, at three miles and a half from the north end of the Hope Reef, reef b; and at fifteen miles from it you will be abreast of e; and five miles farther on you will pass Captain Cook's Turtle Reef, which has a dry sand at its north end. These three reefs will be to the eastward of your course. The current sets to the North-West, so that your course must be directed accordingly. In coasting along the shore, you will discern the summits which are marked on the chart. The high conical hill, on the south side of the entrance of Endeavour River, is Mount Cook, bearings of which, crossed with the summit of Cape Bedford, or any of the particularized summits or points will give the vessel's place, by which the effects of the current, which is generally very slight, will be perceived: on one occasion we found a current in the space between the Endeavour Reef and Turtle Reef of two miles an hour to the North-West. Being off Cape Bedford, and steering to the North 1/2 West, you will see the Three Isles ahead: steer between them and the low wooded island; and direct your course round Cape Flattery and Point Lookout, to anchor under the Turtle Group, unless you have time before dark to reach the islands 4, 5, or 6, of Howick's Group. Under which anchorage may be found. In rounding Point Lookout, do not come within two miles and a half of it, to avoid a reef that is on Captain Cook's chart, but which we did not see; it lies a mile and a half north from the peaked hill at the extremity of the point. You may pass without the Turtle Group, or you will find anchorage under Lizard Island, but this is not recommended, both because the wind is generally fresher as you increase your distance from the shore, and because it lengthens the distance.
