BASS'S STRAITS—WRECK REEF.
7

passing through Bass's Straits we found, from the cross bearings of several islets, that the chronometer deviated widely from the truth: it was, therefore, evident that no reliance could prudently be placed on the longitude thus ascertained; this circumstance, however, caused us no uneasiness, being fortunately favoured with other and unerring celestial time-keepers.

We had scarcely got round Cape Howe when the wind shifted to the northward, and, after two days fruitlessly spent in standing off and on, we stretched out to the eastward until we obtained a favourable breeze. On the 6th of May we passed the parallel of Port Jackson, in longitude 157° 30', when, the wind being still fair, we shaped a course, so as to pass close to the eastward of Cato's bank. At noon, on the 9th, we were one mile north, and ten miles east of it, according to chronometer corrected from Kent's group; but satisfactory lunar observations placed us twenty miles farther to the eastward. The course was, therefore, altered a little more to the westward, that we might obtain a sight of "Bird Islet" on Wreck Reef, in compliance with the generally received opinion, that every vessel bound through Torres' Straits by the outer passage ought to do so; as, from the position of Wreck Reef being well known, a good opportunity is thereby afforded of comparing the chronometer.

At midnight we had passed Bird Islet, as the latitude was ascertained to be 22°.9' south, by the meridian altitudes of several stars taken, in the order of their
