Islet 6, in latitude 13 degrees 29 minutes, longitude 143 degrees 38 minutes 26 seconds, is a very small, low, woody islet, with a reef extending for three-quarters of a mile off its north and south ends.
A reef lies two miles and one-third North 72 1/2 degrees West from islet 6, and South 59 degrees East from the summit of Cape Sidmouth; this reef is not more than a quarter of a mile in extent, and has a rock in its centre, that is uncovered at half tide; it is a brown looking shoal, and therefore of dangerous approach.
Off ROUND HILL there is a sandbank covered by the sea; it lies about two miles from the shore, and about East-North-East from Round Hill summit.
q is a small, brown, rocky shoal, that is not visible until close to it; it bears South 60 degrees East, four miles from the extremity of Cape Sidmouth.
CAPE SIDMOUTH is rather an elevated point, having higher land behind it; and at about nine miles in the interior, to the West-North-West, there is a rounded summit: at the extremity of the cape there are two remarkable lumps on the land, in latitude 13 degrees 24 minutes 20 seconds, and longitude 143 degrees 30 minutes. The cape is fronted by several rocky shoals, and ought not to be approached within four miles.
r is a sandbank, on which we had two and a half fathoms; but from the nature of the other neighbouring reefs, s and t, it is perhaps rocky also, and may be connected with them. It lies four miles and a quarter North 32 degrees East from Cape Sidmouth, and West 1/2 North from islet 7.
6 1/2 and 7 are two bare sandy islets, situated at the north ends of reefs extending in a North-North-West direction; the reef off the islet 6 1/2 is four miles and a half in length, and that off 7 is two miles and a half long: 6 1/2 is in latitude 13 degrees 23 minutes 20 seconds, longitude 143 degrees 39 minutes 30 seconds; 7, in latitude 13 degrees 21 minutes 20 seconds, and longitude 143 degrees 36 minutes 10 seconds.
8 and 9 are two low, woody islets of about a mile and a quarter in diameter. Some shoal marks on the water were observed opposite these islands, but their existence was not ascertained. Both the islets are surrounded by coral reefs, of small extent.
NIGHT ISLAND, its north end in latitude 13 degrees 13 minutes 8 seconds, and longitude 143 degrees 28 minutes 40 seconds, is a low woody island, two miles long, but not more than half a mile wide; it is surrounded by a coral reef, that does not extend more than a quarter of a mile from its northern end. On the south side, and within it, the space seemed to be much occupied by reefs, but they were not distinctly made out, on account of the thickness of the weather. There was also the appearance of a covered shoal, bearing North 55 degrees East from the north end of the island, distant four miles.*
(*Footnote. Observed many shoals to the North-West of Night Island; one bore East-North-East, two miles and a half from its north point; we saw much shoal water to seaward. Roe manuscript.)
