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.  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.
