150 degrees 28 minutes. (Horsburgh volume 2 page 509.)

BETWEEN the parallels of 16 degrees 50 minutes and 17 degrees 45 minutes,
and the meridians of 150 degrees 30 minutes and 152 degrees 30 minutes,
there are several very extensive reefs, various parts of which have been
seen, according to the following accounts.

Lieutenant Vine saw a DRY BANK in latitude 17 degrees 46 minutes, and
longitude 151 degrees 40 minutes. See the account of the shoal described
by M. Tregrosse.

Mr. Brodie, Commander of the brig Alert, in October, 1817, saw A REEF
extending for a considerable distance in a North-East and South-West
direction. The Alert ran along the reef for twenty-five miles: about the
centre Mr. Brodie saw two sand islets in latitude 17 degrees 2 minutes,
and longitude 151 degrees 49 minutes.

LIHOU'S SHOAL, probably a part of the above reefs seen by Lieutenant Vine
and from the Alert, lies in latitude 17 degrees 25 minutes, and longitude
151 degrees 45 minutes: it is forty-six miles in length, and lies
North-North-East and South-South-West.

A very extensive RANGE OF SHOALS and ISLETS was seen by M. Tregrosse, of
the French brig Les Trois Freres, in company with the brig Jessie, in
1821, according to the subjoined account.

On the 19th June, the two brigs in company fell in with a range of reefs,
terminated to the eastward by two sandy islets, the easternmost of which
is in 151 degrees 47 minutes (149 degrees 27 minutes East of Paris); the
vessels hauled to the wind immediately, but finding they could not pass
to windward, bore up, and ran along the shoal from eight a.m. to four
p.m., at the distance of a league and a half. Altogether they counted
seven islets, three of which were covered with shrubs, and the whole
connected by a reef, on the edge of which the sea broke heavily: they
were called GOVERNOR FARQUHAR'S GROUP: the westernmost islet is in 17
degrees 39 minutes, and 151 degrees 27 minutes (149 degrees 7 minutes
East of Paris) and appeared to terminate the group. As it was near
sunset, the vessels hauled to the wind for the night, and at daylight
bore up on a north course: soon afterwards they saw an islet
West-North-West; they, however, continued to steer North until eight
o'clock, and then, having run nine miles, saw another island
North-North-East. On attempting to steer between the isles, they were
found to be connected, and having sounded in eleven fathoms, the vessels
