on the east end, appeared to have some vegetation : the rocks 
in general were six or eight feet above the water, and the 
surf broke violently on the N.E. and S.E. points in view. 
The shoal trends in a W.b.N. direction for six or seven 
miles.” It is distinguished on the chart by the name of 
ASHMORE’S SHOAL. 
SCOTT’S REEF (see Horsburgh, vol. i. p. 102) was dis- 
covered by Captain Heywood, R. N., in 1811: the north- 
west end is in latitude 13° 52^', and longitude 121° 59'; 
thence it extends S. 16° E. for eighteen or nineteen miles 
to the north-east point, in latitude 14° 1', and longitude 
122° 16'; the south extent was not ascertained. It is 
ninety-seven miles due East from the situation assigned to 
Dampier’s Rocks. The Cartier also struck upon a shoal 
hereabouts, and Captain Horsburgh seems to think that there 
is little doubt of Scott’s Reef being the same that Dampier 
saw, as well as that on which the Cartier struck. 
ROWLEY’S SHOALS consist of three separate reefs, 
the westernmost is the Imperieuse, the middle Gierke’s, and 
the north-easternmost the Mermaid’s. The Imperieuse is 
tea miles in length from north to south, and its greatest 
breadth five miles : it is surrounded by very deep water, 
and near the eastern edge, in latitude 17° 35', and longi- 
tude 118° 51', are some dry rocks. Clerke’s Shoal (south 
end in latitude 17° 28', longitude 119° 18') extends to 
the north-west, and probably joins the Minstrel’s Shoal^ 
which is described below, and, if this is the case, trends 
N.N.W.iW'. for seventeen miles. The south end of Mer- 
maid’s Shoal is in 17° 12' S., and 119° 35' E., and extends 
to the northward for seven miles; but its termination in 
that direction was not seen. The edges of all these reefs
