If the tides are regulated by the moon, it is high-water by the shore at
this place on the days of the new and full moon, about four o'clock. The
perpendicular rise and fall is very inconsiderable, not exceeding four
feet at most. In Christmas Sound it is high-water at half past two
o'clock on the days of the full and change, and Mr Wales observed it to
rise and fall on a perpendicular three feet six inches; but this was
during the neap tides, consequently the spring tides must rise higher.
To give such an account of the tides and currents on these coasts as
navigators might depend on, would require a multitude of observations,
and in different places, the making of which would be a work of time. I
confess myself unprovided with materials for such a task; and believe
that the less I say on this subject the fewer mistakes I shall make. But
I think I have been able to observe, that in Strait Le Maire the
southerly tide or current, be it flood or ebb, begins to act on the days
of new and full moon about four o'clock, which remark may be of use to
ships who pass the strait.

Were I bound round Cape Horn to the west, and not in want of wood or
water, or any other thing that might make it necessary to put into port,
I would not come near the land at all. For by keeping out at sea you
avoid the currents, which, I am satisfied, lose their force at ten or
twelve leagues from land; and at a greater distance, there is none.

During the time we were upon the coast we had more calms than storms,
and the winds so variable, that I question if a passage might not have
been made from east to west in as short a time as from west to east; nor
did we experience any cold weather. The mercury in the thermometer at
noon was never below 46°; and while we lay in Christmas Sound it was
generally above temperate. At this place the variation was 23° 30' E.; a
