board a tolerably lofty vessel, when between
the two, this rock may be seen, or
the breakers upon it, just at the time one
gets sight of the outermost Fugle-Skiaer;
but if the weather is in the least de©gree
hazy, the vessel would be too far from the
Fugle-Skiaer to enable a person to see it,
so long as the Blinde Fugle-Skiaer was in
sight. When I approached the Blinde
Fugle-Skiaer I determined, according to
the directions Lieutenant Grove had given
me, to steer directly for it, and, although
we consequently were continually in expectation
of seeing it, yet we did not
discover it until we were only at the distance
of a few cables’ lengths, when we
saw the sea breaking; over it.
Notwithstanding that I had not an
observation for the variation of the compass,
when close to the Fugle-Skiaerene, yet I
c!in judge nearly to a certainty from other
observations, that, in the year 1786, it
was from 36° to 37° north-westerly: and,
as in the same year, I found it immediately
on the western side of Shetland to
be 26°, it consequently follows that the
variation between Shetland and Iceland is,
as nearly as can be calculated, §° for every
degree of longitude we go to the westward.
The variation increases very much afterwards
to the westward of Iceland, and
likewise when steering to the northward.
I have observed the variation in Faxe Bay,
and found it to be in the interior part of
it from 370 to 38°, and, at the outer extremity
of the same bay, from 38° to 39°;
still higher, off Staal-bierg, the northern
point of Brede-Bughten (Broad Bay), it was
40° direct westerly. In the channel, under
65° of latitude, and 35° of longitude, I
found the variation by a series of observations,
to be 45° 10'V*
