COASTS OF AUSTRALIA.

at noon, it was close to us, at which time our ^ 
latitude was by observation 17° 33° 12", from March 15. 
which I deduce the situation of the north end of 
the shoal to be in 
Latitude 17° 3l' 24" : 
Longitude 118° 50' 30': 
the longitude being ascertained by chronometers 
from Depuch Island, corrected afterwards for our 
arrival at the north coast. 
On rounding the north end of the shoal, sound- 
ings were ineffectually tried for, with 120 fa- 
thoms : soon afterwards, we bore up on an 
eastern course, and in the evening saw another 
extensive shoal ; within two miles of the south 
end of which, we sounded with 170 fathoms of 
line without reaching the bottom. 
The south end of the second shoal, is in 
Latitude l7 c ’28 / 5 // : 
Longitude 119° 18' 00" : 
it stretches in a N.‘ W. direction for seven or eight 
miles, and to the eastward, the breakers extended 
beyond the mast-head horizon ; its limit, there- 
fore, in the latter direction, remained undeter- 
mined. 
The next morning a third shoal was disco- is. 
vered, the south-east end of which, is in 
Latitude 17° 1 0' : 
Longitude 119° 35'.
