PE LOCKER, a distance of thirteen
miles, and with the same barren character for twenty miles further,
forming the east side of Exmouth Gulf. ROSILY, and THEVENARD ISLES are
low and sandy; they were seen by us at a considerable distance.

BARROW'S ISLAND, of about forty miles in circumference, is of moderate
height and level aspect, but of very sterile and barren appearance. A
considerable reef extends towards the main from its south-east side,
where there is also a small islet: on the north-east side are three
islets; the two outermost of which are low and rocky. The west coast of
Barrow's Island was seen by the French, who thought it was part of the
main; they named its north-west end, CAPE DUPUY, and its south end, CAPE
POIVRE. At ten miles South 25 degrees West from the last cape, the French
charts have assigned a position to a reef: and four miles North 10
degrees East from Cape Dupuy is another. Neither were noticed by us,
since we did not approach this part sufficiently near to see them if they
do exist; of which, from the account of the French, there can be but
little doubt.

LOWENDAL ISLAND and TRIMOUILLE ISLAND were seen by us, but not any
vestige of HERMITE ISLAND, which the French have placed in their chart.
From M. de Freycinet's account, the two latter islands were seen at
different times; and since Trimouille Island has a reef extending for
five miles from its north-western extremity, as Hermite Island is
described to have, there seems to be good reason to suppose that there is
but one; had there been two, we should have seen it on passing this part
in 1822.*

(*Footnote. Vide volume 1.)

From the reasons mentioned in the narrative, there remains no doubt in my
mind that Barrow's Island, and Lowendal and Trimouille Islands (which the
French called the Montebello Islands) are the long lost TRYAL ROCKS. The
latitude and description answer very exactly; the longitude alone raises
the doubt, but the reckonings of former navigators cannot be depended
upon, and errors of ten or twelve degrees of longitude were not rare, of
which many proofs might be found, by comparing the situations of places
formerly determined with their position on the charts of the present
time. Many old navigators were not very particular; and never gave the
error of their account upon arriving at their destined port, either from
shame or from carelessness and indifference.

A reef of rocks is said to exist in latitude 20 degrees 17 m
