This may, at first sight, seem to contradict what has been before laid
down, as to the variation, and the causes of it: but, when strictly
considered, they will be found to agree very well; for when it is
asserted that veins of loadstone have nothing to do with the variation of
the compass, it is to be understood of the constant variation of a few
degrees to the east, or to the west: but in cases of this nature, where
the variation is absolutely irregular, and the needle plays quite round
the compass, our author's conjecture may very well find place: yet it
must be owned that it is a point far enough from being clear, that mines
of loadstone affect the compass at a distance; which, however, might be
very easily determined, since there are large mines of loadstone in the
island of Elba, on the coast of Tuscany.



CHAPTER IV: HE DISCOVERS A NEW COUNTRY TO WHICH HE GIVES THE NAME OF VAN
DIEMEN'S LAND.


On the 24th of the same month, being in the latitude of 42 degrees 25
minutes south, and in the longitude of 163 degrees 50 minutes, I
discovered land, which lay east-south-east at the distance of ten miles,
which I called Van Diemen's Land. The compass pointed right towards this
land. The weather being bad, I steered south and by east along the
coast, to the height of 44 degrees south, where the land runs away east,
and afterwards north-east and by north. In the latitude of 43 degrees 10
minutes south, and in the longitude of 167 degrees 55 minutes, I anchored
on the 1st of December, in a bay, which I called the Bay of Frederic
Henry. I heard, or at least fancied I heard, the sound of people upon
