The island Threehills lies south four leagues from the coast of Apee, and S.E. 1/2 S., distant seventeen leagues from Port Sandwich; to this, and what hath been already said of it, I shall only add, that W. 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° 54', longitude 169° 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° 3', longitude 170° 4', and S. 30° 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.
