endix to this volume, was 122 deg. 15' 42"; but from the two best time
keepers, in which, from the short period since leaving King George's
Sound, I put most confidence, it will be more correctly 122 deg. 14' 14" E.

_Dip_ of the south end of the needle, taken on shore upon the granite
rock, 66 deg. 4' 0"

But I am inclined to think it was attracted by the granite; and that,
had the needle been considerably elevated, it would not have shown more
dip than at King George's Sound, where it was 64 deg..

The _variation_ deduced from observations taken on shore, morning and
evening, with three compasses placed on the same rock, was 2 deg. 35' west;
with Walker's meridional compass, 4 deg. 55'; and with the surveying
theodolite 0 deg. 30' west.* An amplitude taken on board the ship, with the
head east-south-east, gave 7 deg. 25', which, reduced to what it should be
with the head in the meridian, is 4 deg. 26' west. The mean, and what I
consider to be nearest the true variation in this neighbourhood, will be
3 deg. 6' west.

[* It is remarkable, that the difference between these three kinds of
instruments is directly the reverse here of what it was in King George's
Sound.]

This is what I allowed upon the bearings taken with the theodolite upon
the top of the hill behind the bay, and it appeared to be the same upon
two small islands, one to the east and the other west, where Mr. Thistle
took angles; but at Mondrain Island there seemed to be considerable
differences.

Before entering the archipelago, the variation was observed to be 9 deg. 21'
west, with the ship's head east-south-east; but at three leagues to the
east of Termination Island, in the following year, and with the head at
east-north-east, it was no more than 3 deg. 50' west. From the first, I
should deduce the true variation on the west side of the archipelago to
be 6 deg. 28', and off Termination Island, from the second, to be 0 deg. 57'
west; both of which coincide with the other observations in showing the
islands of the archipelago to possess a considerable degree of magnetic
attraction.

The rise of _tide_ in Lucky Bay was so trifling, that under the
circumstances of our stay no attention was paid to it.

THURSDAY 14 JANUARY 1802

In the morning of the 14th, the wind being then light from the northward,
we got under way and steered for Mondrain Island. In our route eastward
from thence, several low rocks and patches of breakers were left on each
sid
