The summit of Forbes' Island is in latitude 12 degrees 16 minutes 35 seconds, and longitude 143 degrees 18 minutes 50 seconds.
h, a coral reef, with some dry rocks near its north end, is about one mile long, and separated from i by a narrow pass.

The south end of h bears from the summit of Forbes' Island West 1/4 South seven miles.
i and k, coral reefs, lying North-West, having a very narrow channel between them; the former is covered, but the latter has a dry sandy key at its north-west end, in latitude 12 degrees 12 minutes 20 seconds, and longitude 143 degrees 10 minutes 5 seconds.
PIPER'S ISLETS are four low bushy islets upon two circular reefs, with a passage separating them of a quarter of a mile wide; the reefs have each two islets upon them, and a dry rocky key round their western edge: the centre of the narrowest part of the channel between them is twelve and a half fathoms deep, but abreast the south end of the south-easternmost shoal there is ten and a half fathoms.
l, a circular coral reef, a mile and a half in diameter, with a dry rock at its east end, in latitude 12 degrees 9 minutes 5 seconds, and longitude 143 degrees 11 minutes.
YOUNG ISLAND, a small islet on a coral reef of about half a mile in extent, in latitude 12 degrees 6 minutes 50 seconds, and longitude 143 degrees 7 minutes.

(See volume 1.) m, a coral reef, about two and a half miles long, having a dry rock at its north end; it bears South 40 degrees West, three miles from the summit of Haggerston's Island.
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.
