On the 31st, at noon, the S. or S.W. point of the island bore N. 62° E., distant four leagues. This forms the N.W. point of what I call Bougainville's Passage; the N.E. point at this time bore N. 85° E., and the N.W. end of Mallicollo from S. 54° E. to S. 72° E. Latitude observed 15° 45' S. In the afternoon, in stretching to the east, we weathered the S.S.W. point of the island, from which the coast trends east, northerly. It is low, and seemed to form some creeks or coves; and, as we got farther into the passage, we perceived some small low isles lying along it, which seemed to extend behind St Bartholomew Island.
Having now finished the survey of the whole archipelago, the season of the year made it necessary for me to return to the south, while I had yet some time left to explore any land I might meet with between this and New Zealand; where I intended to touch, that I might refresh my people, and recruit our stock of wood and water for another southern course. With this view, at five p.m. we tacked, and hauled to the southward with a fresh gale at S.E. At this time the N.W. point of the passage, or the S.W. point of the island Tierra del Espiritu Santo, the only remains of Quiros's continent, bore N. 82° W., distant three leagues. I named it Cape Lisburne, and its situation is in latitude 15° 40', longitude 165° 59' E.
The foregoing account of these islands, in the order in which we explored them, not being particular enough either as to situation or description, it may not be improper now to give a more accurate view of them, which will convey to the reader a better idea of the whole groupe.
The northern islands of this archipelago were first discovered by that great navigator Quiros in 1606; and, not without reason, were considered as part of the southern continent, which, at that time, and until very lately, was supposed to exist. They were next visited by M. de Bougainville, in 1768; who, besides landing on the Isle of Lepers, did no more than discover that the land was not connected, but composed of islands, which he called the Great Cyclades. But as, besides ascertaining the extent and situation of these islands, we added to them several new ones which were not known before, and explored the whole, I think we have obtained a right to name them; and shall in future distinguish them by the name of the New Hebrides. They are situated between the latitude of 14° 29' and 20° 4' S., and between 166° 41' and 170° 21' E. longitude, and extend an hundred and twenty-five leagues in the direction of N.N.W. 1/2 W. and S.S.E. 1/2 E.
The most northern island is that called by M. de Bougainville, Peak of the Etoile; it is situated, according to his account, in latitude, 14° 29', longitude 168° 9'; and N. by W., eight leagues from Aurora.
The next island, which lies farthest north, is that of Tierra del Espiritu Santo. It is the most western and largest of all the Hebrides, being twenty-two leagues long, in the direction of N.N.W. 1/2 W. and S.S.E. 1/2 E., twelve in breadth, and sixty in circuit. We have obtained the true figure of this island very accurately. The land of it, especially the west side, is exceedingly high and mountainous; and, in many places the hills rise directly from the sea. Except the cliffs and beaches, every other part is covered with wood, or laid out in plantations. Besides the bay of St Philip and St Jago, the isles which lie along the south and east coast, cannot, in my opinion, fail of forming some good bays or harbours.
The next considerable island is that of Mallicollo. To the S.E. it extends N.W. and S.E., and is eighteen leagues long in that direction. Its greatest breadth, which is at the S.E., end, is eight leagues. The N.W. end is two-thirds this breadth, and near the middle, one-third. This contraction is occasioned by a wide and pretty deep bay on the S.W. side. To judge of this island from what we saw of it, it must be very fertile and well inhabited. The land on the sea-coast is rather low, and lies with a gentle slope from the hills which are in the middle of the island. Two-thirds of the N.E. coast was only seen at a great distance; therefore the delineations of it can have no pretensions to accuracy; but the other parts, I apprehend, are without any material errors.
St Bartholomew lies between the S.E. end of Tierra del Espiritu Santo, and the north end of Mallicollo; and the distance between it and the latter is eight miles. This is the passage through which M. de Bougainville went; and the middle of it is in latitude 15° 48'.
The Isle of Lepers lies between Espiritu Santo and Aurora Island, eight leagues from the former, and three from the latter, in latitude 15° 22', and nearly under the same meridian as the S.E.. end of Mallicollo. It is of an egg-like figure, very high, and eighteen or twenty leagues in circuit. Its limits were determined by several bearings; but the lines of the shore were traced out by guess, except the N.E. part where there is anchorage half a mile from the land.
Aurora, Whitsuntide, Ambrym, Paoom, and its neighbour Apee, Threehills, and Sandwich Islands, lie all nearly under the meridian of 167° 29' or 30' E., extending from the latitude of 14° 51' 30", to 17° 53' 30".
