On the eastern side of the northernmost island there 
is a bay fronted by a coral reef, but it is too exposed 
to the prevailing winds to be safe. It is' here that the 
Frederick (merchant ship) was wrecked in 1818. 
CAPE FLINDERS, in latitude 14° 8', longitude 144° 10' 
20", is the north extremity of the island ; it may be passed 
close to with twelve fathoms : the best anchorage is under 
the flat-topped hill, at a quarter of a mile from the shore, in 
ten fathoms mud. The variation is 5° 20' E. It is high 
water at full, and change at a quarter past nine. 
In the offing is a low wooded island of more than a mile 
in diameter. 
CLACK’S ISLx4ND is a high rock, situated at the south- 
east end of reef b, in latitude 14° 4' 45", and longitude 
144° 11' 45", and, being a bare black rock, with no ap- 
parent vegetation, is a conspicuous object: there is another 
rock on its north-east end. (See vol. ii. p. 25.) The reef is 
of circular shape, and three miles in diameter. 
The shoal marked a was not seen by us. H. M. sloop 
Satellite struck upon it in June, 1822, on her passage to 
India. The following marks for it were obligingly commu- 
nicated to me by Captain M. J. Currie, of H. M. sloop 
Satellite, who sent a boat to examine it upon her second 
voyage the following year : — 
“ In crossing the northern part of Bathurst Bay, and 
nearly in mid-channel, between Cape Flinders and the low 
wooded island, there is a small patch of sunken rocks, lying 
north and south, not more than a cable’s length in extent, the 
least water being one fathom. The Satellite grounded on 
them in two fathoms, in June, 1822. I sent a boat to ex- 
amine this shoal in making the same passage in August,
