n, an extensive, irregular-shaped, coral reef, seven miles long, and from one to four broad; it is separated from o by a narrow tortuous channel, but not safe to pass through: both n and o are covered. There is a safe passage between these reefs and Haggerston's Island, of a mile and a half wide; but there is a small reef detached from the north-west end of n, which should be avoided, although there is probably sufficient depth of water over it for any ship: it was seen from the summit of the island, from whence another coral patch was observed at about one mile to the westward, of which we saw no signs. p is a small reef, of about a mile and a quarter in extent; it was seen from the summit of Haggerston's Island, as was also another reef, seven miles South by East from it: the positions of these reefs are doubtful. HAGGERSTON'S ISLAND is high and rocky; the summit is in latitude 12 degrees 1 minute 40 seconds, and longitude 143 degrees 12 minutes; it is situated at the South-South-West extremity of a coral reef, of nearly two miles in length; its northern side is furnished with some trees and a sandy beach. At the north end of the reef are two dry patches of sand and rocks. It is separated from the islands of Sir Everard Home's Group by a channel nearly three miles wide, quite free from danger; but in passing through it, the tide or current sets to the North-North-West, round the reef off Haggerston's Island. (See volume 1.) SIR EVERARD HOME'S GROUP consists of six islands: the two south-westernmost are rocky, and one of them has two peaks upon it, which, from the southward, have the appearance of being upon the extremity of Cape Grenville: the south-easternmost has a hillock, or clump of trees, at its south-east extremity, in latitude 11 degrees 57 minutes 40 seconds, and longitude 143 degrees 11 minutes. The outer part of this group is bold to, and the islands may be approached, but the space within them appeared to be rocky: there is a passage between the group and Cape Grenville. The merchant ship Lady Elliot in passing through it, found overfalls with eighteen fathoms. Round Cape Grenville is MARGARET BAY, fronted by SUNDAY ISLAND, elevated and rocky, but not so high as Haggerston's Island, with good anchorage under its lee. q is a covered reef of about a mile in extent, in latitude 11 degrees 55 minutes, five or six miles to the East-North-East of Sir Everard Home's Group. SIR CHARLES HARDY'S ISLANDS are high and rocky, and may be seen five or six leagues off; the summit is in latitude 11 degrees 53 minutes 20 seconds, and longitude 143 degrees 23 minutes 40 seconds. r is a covered reef; and s, a reef, with a dry sandy key upon it. COCKBURN ISLES are rocky, and may be seen four leagues off.* (*Footnote. There is a dry sand bearing South-West by West 1/2 West, two miles and a half from the southernmost Cockburn Island, and there are many shoals of great extent to the northward of the group.
