iles, and determined its position. It forms a large lagoon, with an
opening, not appearing to be a ship passage, midway on its western side;
marked by a dry bank just within it, in latitude 14 degrees 3 minutes 30
seconds South and longitude 6 degrees 4 minutes 45 seconds East of Swan
River. The eastern extreme of the reef was not seen; the southern limit
is in latitude 14 degrees 15 minutes South; and the north-west extreme
being in 13 degrees 55 minutes South, and longitude 6 degrees 2 minutes
East of Swan River, gives it an extent of twenty miles in a north and
south direction.

SCOTT'S REEF.

Captain Owen Stanley, in March, 1840, discovered a shoal about sixteen
miles to the North-North-East of Scott's Reef; he considered its extent
from east to west to be about five miles; but from the masthead the south
end of it could not be seen. It did not appear to have more than two or
three feet water on it. The north point, Captain Stanley places in
latitude 13 degrees 39 minutes South, longitude 121 degrees 56 minutes
East; or 6 degrees 11 minutes East of Swan River.*

(*Footnote. This reef was seen by the Seringapatam merchant ship in
1842.)

We now began to feel a westerly current, which increased to a knot and a
half as we got near Rottee; the winds being moderate, between East and
East-South-East.

PULO DOUW.

July 23.

The weather was hazy: the high land of Rottee was seen in the forenoon,
the highest part of the island, a rather pointed hill, bearing North 60
degrees East. At 1 P.M. we saw Pulo Douw, which we endeavoured to
weather, but the current prevented us. It is a remarkable island, with a
gap in the centre and a clump of trees, that looks like a sail when first
seen, on the north-west end, which terminates in a low sandy point. This
is also the case with the south-east extreme, off which a reef extends
for about half a mile; indeed, there appeared to be no ship passage
between the sandy islets that lie to the east of Pulo Douw and Rottee. We
rounded the north-west end of the former at the distance of a mile and a
half, passing through some heavy ripplings, apparently an eddy setting to
the north-east round the island. Pulo Douw appeared to be thickly
inhabited, and was encircled by a reef, except at its North-North-West
point, where there is a cliffy projection. Angles were taken for fixing
the position of the islets between Pulo Douw and Rottee, which we found
to be wrongly placed. The Scotch Bonnet,
