The limits assigned by this officer to the extent of the rocky ground, are the parallels of 20 degrees 40 minutes, and 21 degrees 50 minutes, and the meridians of 158 degrees 15 minutes and 159 degrees 30 minutes.

A sandy islet was also seen by him, surrounded by a chain of rocks in 21 degrees 24 1/2 minutes South, and 158 degrees 30 minutes East.

The ship Minerva also struck soundings in eight fathoms, with the appearance of shoaler water to the South-West; this last danger is in a line between the two shoals in about longitude 159 degrees 20 minutes.
(See Horsburgh Supp.

page 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, September 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.
