In 18 degrees 32 minutes and 146 degrees 41 minutes is a reef, on which the San Antonio, merchant brig, struck: its position was not correctly ascertained, as the accident happened in the night.
POINT HILLOCK is in latitude 18 degrees 25 minutes, and longitude 146 degrees 20 minutes; it is a low point projecting to the eastward, under Mount Hinchinbrook.
CAPE SANDWICH is the north-east extremity of the sandy land that stretches to the northward from the base of Mount Hinchinbrook, which is so high as to be visible for eighteen leagues: the mount is topped with a craggy summit, seven miles in length from north to south.
There is a reef that extends for nearly a mile and a half off the cape, having a rocky islet at its extremity. The cape is in latitude 18 degrees 13 minutes 20 seconds, and longitude 146 degrees 16 minutes 40 seconds. The peak at the north end of Mount Hinchinbrook is in latitude 18 degrees 21 minutes 30 seconds, and longitude 146 degrees 15.
BROOKE'S ISLANDS lie four miles north from Cape Sandwich; they consist of three rocky islets, besides some of smaller size; the whole are surrounded by a coral reef.
From Cape Sandwich the land extends, low and sandy, in a North-West direction for five miles to a point, which is terminated by a hill. Between this and Goold Island there appears to be a navigable strait leading into Rockingham Bay.
GOOLD ISLAND, the summit of which, formed by a conical hill covered with wood, in latitude 18 degrees 9 minutes 35 seconds, and longitude 146 degrees 9 minutes, is about two miles long: the south-west point of the island is a long strip of low land, with a sandy beach; at the eastern end of which there is a run of water; and fuel may be cut close to the shore. High water takes place at full and change at three quarters past ten.
ROCKINGHAM BAY appears to be a spacious harbour. At the bottom there was an appearance of an opening that may probably communicate with an inlet on the south side of Point Hillock, and insulate the land of Mount Hinchinbrook. There is good anchorage in the bay in four and five fathoms mud, near Goold Island.
The natives are very friendly here, and will come off and visit the ship.
FAMILY ISLES consist of seven small rocky islets, covered with a stunted vegetation.
