a bank of soundings of the depth of from one hundred and Reefs.

seventy to one hundred and twenty fathoms. (See Hors- CQ^gt 
burgh, vol. i. p. iOl.) 
Minstrel’s Shoal (see Horsburgh’s Supp. p. 52), its 
north-east end is in 17° 14' S., and 118° 57' E., or 5° 28' 
East by chronometer, from the coast of New Holland in 
latitude 23° 10' S. The longitude of that part of the coast 
by my survey, is 113° 42'; this will make the Minstrel’s 
Shoal in 119^ 10', which agrees very well with Gierke’s 
Reef, the centre reef of Rowley’s Shoals, of which it is cer- 
tainly the north end ; so Captain Horsburgh also supposes. 
A ship called the Lively was wrecked on a coral reef 
in about 16° 30' S., and 119° 35' E. 
RITCHIE’S REEF, or the Greyhound's Shoal. The situ- 
ation of this reef is recorded by Captain Horsburgh (see 
Supp. p. 38) to be in latitude 19° 58', and longitude 114® 
40^' ; but, by a letter published in the Sydney Gazette by 
Lieutenant Ritchie, R.N., the commander, it would appear to 
be in 20® 17' 40", longitude by lunars 114° 46' 6". 
The Russian ship Rurick, in 1822, saw a dry rock R„ck off 
above water off the south-east coast of Van Diemen’s Land, V.D.Land 
in latitude 44°, and longitude 147° 45'. 
A rock was also seen by the ship Lord Sidmouth in 
1819, in latitude 43° 48', and longitude 147® 15'.
