1819. July 26.

On our voyage from Torres Strait to the western head of the Gulf of
Carpentaria, which is Cape Arnhem, no incident occurred of sufficient
interest to be worth recording; but no sooner had we passed Torres Strait
than a very sensible difference was perceived in the temperature: the
thermometer was observed to range between 75 and 83 degrees, which was
about 3 degrees higher than it did on the south side of the Strait; this
change produced a drier air and finer weather and soon restored our
invalids to perfect health.

July 27.

Soon after daylight on the 27th Wessel's Islands, which had been seen the
preceding evening, were descried bearing from West-North-West to
South-West by West; and shortly afterwards lower land was observed more
to the northward, towards the extremity of which we steered.

The eastern side of Wessel's Islands presents a level aspect; only a few
shrubby trees appear at intervals to break the uniformity of its gently
undulating outline. The point, which is named Cape Wessel, is the
extremity of the northernmost island of the group and is separated from
that to the southward of it by a narrow and apparently a rocky strait.

On approaching within a mile and a half of the Cape we passed through a
strong rippling tide without having soundings with fifteen fathoms. Six
natives were seen sitting on the verge of the cliffs that overhang the
Cape, watching us as we passed; and farther on two more were observed
walking on the beach. On the west side of the Cape is a small sandy bay
in which there appeared to be good anchorage.

In passing this bay we fell into another strong tide race, in which the
sea curled and foamed about us as if we were in the midst of breakers;
but, as before, no bottom was found with fifteen fathoms. The water was
very thick, from the mud being stirred up by the violence of the tide,
which must have been setting at the rate of three miles and a half per
hour; for we were going nearly five knots by the log, and yet made
scarcely any way: we were therefore obliged to steer more off, to get out
of the influence of the tide, which proved to be the ebb setting to the
North-East.

By a meridional observation at noon the latitude of the Cape was found to
be 10 degrees 59 1/4 minutes, which is 19 minutes more northerly than the
land which bounded Captain Flinders' view when he passed by in the
Cumberland. The breadth of these islands is very inconsiderable; for as
we
