REEF h is an extensive reef, having high breakers on its outer edge: it is more than four miles long, and separated from the north end of g by a channel a mile wide. REEF i has several detached reefs about it, on the northernmost are two rocky islands, and to the southward, on a detached shoal, there is a bare sandy islet that is perhaps occasionally covered by the tide: its south-westernmost extremity and the summit of Lizard Island are in the line of bearing of North 5 degrees West (magnetic) its latitude is 14 degrees 53 minutes 40 seconds. REEF k, in latitude 14 degrees 47 minutes, has a dry sand upon it: its sub-marine extent was not ascertained. REEF l; the position of this reef is rather uncertain, near its western side is a dry key in latitude 14 degrees 47 minutes 30 seconds. m is probably unconnected with the shoal off the south end of Eagle Island. In Captain Cook's rough chart there is twelve fathoms marked between two shoals which must mean the above. EAGLE ISLAND is low and wooded, and situated at the north end of a considerable shoal; its latitude is 14 degrees 42 minutes 20 seconds, and longitude 145 degrees 18 minutes 30 seconds. DIRECTION ISLANDS are two high rocky islands, so called by Captain Cook to direct ships to the opening in the reefs, through which he passed out to sea; they are high and of conical shape, and might be seen more than five or six leagues off was it not for the hazy weather that always exists in the neighbourhood of the reefs; the northernmost is in latitude 14 degrees 44 minutes 50 seconds, longitude 145 degrees 26 minutes 25 seconds: the southernmost is in latitude 14 degrees 50 minutes, longitude 145 degrees 26 minutes 45 seconds. LIZARD ISLAND, about three miles long, is remarkable for its peaked summit, the latitude of which is 14 degrees 40 minutes 20 seconds, and longitude 145 degrees 23 minutes: on its south side is an extensive reef encompassing three islets, of which two are high and rocky: the best anchorage is on its western side under the summit; with the high northernmost of the Direction Islands in sight over the low land, bearing about South-East by compass: the depth is six and seven fathoms sandy bottom. The variation here is 5 degrees 2 minutes East. TURTLE GROUP is four miles to the north of Point Lookout; the islets are encircled by a horse-shoe shaped coral reef, and consist of six islands, all low and bushy. These islands are not laid down with sufficient accuracy as to their relative positions. n is a low wooded island about eleven miles west from Lizard Island; no reef was seen to project from it; it is in the meridian of the observatory of Endeavour River; and in latitude 14 degrees 40 minutes. o is a small coral reef; it lies a mile and a half North 64 degrees West from the north end of n. p is a coral reef, about a mile in extent, separated from o by a channel of a mile wide.
