gth of the reef, they found fourteen fathoms; at a quarter of a mile
off the depth was twenty-five fathoms, but beyond that the bottom was not
reached. It is about three miles in circuit, with deep water in the
centre: the edge is covered, but some straggling rocky lumps show at
intervals above the surface of the water. The east side of the reef
extends about North-North-East and South-South-West for one mile, but the
greatest extent seemed to be West-North-West and East-South-East.

MIDDLETON'S SHOAL is in latitude 29 degrees 14 minutes, and longitude 158
degrees 53 minutes. (See Horsburgh volume 2 page 508.)

CATO'S BANK is in latitude 23 degrees 6 minutes, and longitude 155
degrees 23 minutes. (Flinders volume 2 page 298 and Horsburgh volume 2
page 509.)

WRECK REEF is in latitude 22 degrees 11 minutes 23 seconds, and longitude
155 degrees 18 minutes 50 seconds. (Flinders volume 2 page 330 and
Horsburgh volume 2 page 509.)

CARNS, or MID-DAY REEF, was discovered by Mr. Carns, the master of the
ship Neptune, on the 21st of June, 1818, having taken a departure the day
before from Sandy Cape. It extends east and west for a considerable
distance: the ship passed round the western extremity at two miles off,
and found its bearing from Sandy Cape to be North 21 degrees East, one
hundred and seventy-six miles, and to be in latitude 21 degrees 58
minutes, and longitude 154 degrees 20 minutes. Its eastern limit was not
seen: it consists of a string of sandbanks and rocks, from five to twenty
feet high, with passages between them. (Horsburgh Supp. page 35.)

SIR JAMES SAUMAREZ' SHOAL was seen by Mr. Lihou; it is in latitude 21
degrees 40 minutes, and longitude 153 degrees 46 minutes by chronometer,
which was found correct on making Sandy Cape a day or two afterwards.
There is reason to suppose that many other reefs exist to the North-West
of this position.

KENN'S REEF, discovered by Mr. Alexander Kenn, Master of the ship William
Shand, on her passage from Sydney to Batavia, extends in the direction of
North West by North 1/2 North for ten miles, and is composed of sand and
rocks, some of which, at the south end, were six or eight feet out of the
water: it is six miles broad; the centre of the edge (? north) is in
latitude 21 degrees 9 minutes, and longitude 155 degrees 49 minutes (by
chronometer and lunars): it was found to bear South 67 degrees West, six
miles from Bird Islet, of Wreck Reef.
