Reefs. 
BETWEEN the parallels of 16° 50' and 17° 45', and the 
meridians of 150° 30' and 152® 30', there are several very 
extensive reefs, Various parts of which have been seen, ac- 
cording to the following accounts. 
Lieutenant Vine saw a dry bank in latitude 17° 46', and 
longitude 151° 40'. 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 N.E. and S.W. direction. The Alert ran along the reef 
for twenty-five miles : about the centre Mr. Brodie saw two 
sand islets in latitude 17° 2', and longitude 151° 49'. 
Lihou’s Shoal, probably a part of the above reefs seen 
by Lieutenant Vine and from the Alert, lies in latitude 
17° 25', and longitude 151° 45': it is forty-six miles in 
length, and lies N.N.E. and S.S.W. 
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° 47' (149° 27 ' 
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 dis- 
tance of a league and a half. Altogether they counted seven 
islets, three of which were covered with shrubs, and the 
I whole connected by a reef, on the edge of which the sea 
j broke heavily: they were called Governor Farquhau’s
