Hence the mean dip, with both needles, on shore, was 72 32 3-1/4

On board 72 25 45-1/4

This is as near as can be expected; and shews, that whatever it was
that affected the compasses, whether on board or ashore, it had no
effect upon the dipping needles.

_Tides._

It is high water on the days of the new and full moon at 12^h 20^m.
The perpendicular rise and fall, eight feet nine inches; which is to
be understood of the day-tides, and those which happen two or three
days after the full and new moon. The night-tides, at this time, rise
near two feet higher. This was very conspicuous during the spring-tide
of the full moon, which happened soon after our arrival; and it was
obvious, that it would be the same in those of the new moon, though we
did not remain here long enough to see the whole of its effect.

Some circumstances, that occurred daily, relating to this, deserve
particular notice. In the cove, where we got wood and water, was a
great deal of drift wood thrown ashore; a part of which we had to
remove to come at the water. It often happened, that large pieces of
trees, which we had removed in the day out of the reach of the then
high water, were found, the next morning, floated again in our way;
and all our spouts, for conveying down the water, thrown out
