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. 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 Hagger
