A. 158° 30' E. The ship Minerva also struck soundings in 
Sect. VII. fathoms* with the appearance of shoaler water to the 
Reefs. S.W. ; this last danger is in a line between the two shoals in 
. Coast, longitude 159° 20'. (See Horsburgh, Supp. p. 35.) 
BAMPTON’S SHOAL is laid down in the shape of a 
horse-shoe, of not less than forty- five miles in extent ; on 
the north-east end are two islets with trees. The Avon 
Isles are probably near its south-west extremity: they 
were seen by Mr. Sumner* Master of the ship Avon, Sep- 
tember 18, 1823 ; and are described by him as being three- 
quarters of a mile in circumference, twenty feet high, and 
the sea between them twenty fathoms deep. At four miles 
N.E.b.N. from them the vessel sounded in twelve fathoms, 
and at the same time saw a reef ten or fifteen miles to the 
S.E., with deep water between it and the islets. A boat 
landed on the south-westernmost islet, and found it inha- 
bited only by birds, but clothed with shrubs and wild grapes. 
By observation, these islands were found to lie in latitude 
19° 40', and longitude 158° 6'. 
A reef is laid down in M. Krusenstern’s Atlas of the 
Pacific Ocean (1824) in latitude 17°, and longitude 156°, 
and is there called Mellish Reef. 
A Reef was seen by the ship Frederick, the north- 
east extremity of which is laid down in latitude 20° 44', 
and longitude 150° 32'; it is of semi-circular shape, and 
extends as far south as 21° 2', and appears to be nearly 
twenty miles wide. 
VINE'S HORSE-SHOE SHOAL; its northernmost end 
is in latitude 20° 5', and longitude 151° 50': it presents its 
convex, or outer edge, to the Southward, and extends as 
far as fifteen miles to the South and East
