By N., five
miles from the west point, is a reef of rocks on which the sea continually
breaks.
Nine leagues, in the direction of south, from Threehills, lies Sandwich
Island. Twohills, the Monument, and Montagu Islands, lie to the east of
this line, and Hinchinbrook to the west, as also two or three small isles
which lie between it and Sandwich Island, to which they are connected by
breakers.
Sandwich Island is twenty-five leagues in circuit; its greatest extent is
ten leagues; and it lies in the direction of N.W. by W. and S.E. by E. The
N.W. coast of this island we only viewed at a distance; therefore our chart
of this part may be faulty so far as it regards the line of the coast, but
no farther. The distance from the south end of Mallicollo to the N.W. end
of Sandwich Island, is twenty-two leagues in the direction of S.S E. 1/2 E.
In the same direction lie Erromango, Tanna, and Annatom. The first is
eighteen leagues from Sandwich Island, and is twenty-four or twenty-five
leagues in circuit. The middle of it lies in the latitude of 18 deg. 54',
longitude 169 deg. 19' E., and it is of a good height, as may be gathered from
the distance we were off when we first saw it.
Tanna lies six leagues from the south side of Erromango, extending S.E. by
S. and N.W. by N., about eight leagues long in that direction, and every
where about three or four leagues broad.
The isle of Immer lies in the direction of N. by E. 1/2 E., four leagues
from Port Resolution in Tanna; and the island of Erronan or Footoona East,
in the same direction, distant eleven leagues. This, which is the most
eastern island of all the Hebrides, did not appear to be above five leagues
in circuit, but is of a considerable height and flat at top. On the N.E.
side is a little peak seemingly disjointed from the isle; but we thought it
was connected by low land. Annatom, which is the southernmost island, is
situated in the latitude of 20 deg. 3', longitude 170 deg. 4', and S. 30 deg. E.,
eleven or twelve leagues from Port Resolution. It is of a good height, with
an hilly surface; and more I must not say of it.[7]
Here follow the lunar observations by Mr Wales, for ascertaining the
longitude of these islands, reduced by the watch to Port Sandwich in
Mallicollo, and Port Resolution in Tanna.
