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.  Roe manuscript.)

t and u are two reefs that were seen at a distance, and appeared to be detached from each other.

BIRD ISLES (the Lagoon Islands of Lieutenant Bligh) consist of three low bushy islets encompassed by a reef:  the islands are at the outer verge of the reef, and may be passed within a quarter of a mile; the north-east island is in latitude 11 degrees 44 minutes 15 seconds, and longitude 142 degrees 58 minutes 45 seconds.

McARTHUR’S ISLES consist of four low bushy islets, of which two are very small; they are encompassed by a reef of more than three miles long, and are separated from the Bird Isles by a channel three miles and a half wide.

HANNIBAL’S ISLES are three in number, low and covered with bushes, the easternmost is near the extremity of the reef encircling the whole, and is in latitude 11 degrees 34 minutes 15 seconds, and longitude 142 degrees 51 minutes 20 seconds.*

(Footnote.  There is a dry sand at one mile and three-quarters, and another at two miles and a half North-North-West from North Hannibal Island.)

v and w; these shoals are separated by a safe channel of a mile and a quarter wide; v is circular, and has a dry sand at its north-west edge, and a rocky key at its south-west end; the channel between it and Hannibal’s Islands is two miles and a half wide:  w is nearly four miles long, and is entirely covered; the course between them is west, but, by hauling close round the east end of v, a West by North 1/2 North course will carry a vessel a quarter of a mile to leeward of the west end of w; the north-west extreme of w is three miles and a quarter South 35 degrees West from Islet 1.
