A voyage round the world

by comte Louis-Antoine de Bougainville

Difficult course.

We spent the night upon our tacks; and the 25th, at day-light, found ourselves surrounded with land. Three passages presented themselves to us; one opened to the S. W. the second to W. S. W. and the third almost east and west. The wind was fair for none but the east; and I did not approve of it, as I did not doubt that it would carry us into the midst of the isles of Papua. It was necessary to avoid falling any farther to the northward; for fear, as I have before observed, we should be imbayed in one of the gulphs, on the east side of Gilolo. The essential means for getting out of these critical parts, was therefore to get into a southern latitude; for on the other side of the S. W. passage we observed to the southward an open sea, to the utmost extent of our view, therefore I resolved to ply to windward, in order to gain that outlet. All these islands, which inclosed us, are very steep, of a moderate height, and covered with trees. We did not perceive the least appearance of their being inhabited.

Fourth passage of the line.

At eleven o’clock in the afternoon, we sounded 45 fathom, a sandy bottom; this was one resource. At noon we observed in 00° 5′ N. latitude, having crossed the line a fourth time. At six in the evening we were so far to windward, as to be able to fetch the W. S. W. passage, having gained about three leagues by working the whole day. The night was more favourable, thanks to the moon-shine, which enabled us to turn to windward between the rocks and islands. The current, which had been against us whilst we were passing by the two first passages, likewise became favourable for us as soon as we opened the S. W. passage.

Description of the channel through which we pass.

The channel through which we at last passed out this night, may be about three leagues broad. It is bounded to the westward by a cluster of pretty high islands and keys. Its eastern side, which at first sight we took for the westmost point of the great island, is also nothing but a heap of small islands and rocks, which, at a distance, seemed to form only one body; and the separations between these islands shew at first the appearance of fine bays; this is what we discovered in each tack, that we made towards that shore. It was not till half past four o’clock in the morning, that we were able to double the southmost of the little islands of the new passage, which we called the French Passage. We deepened our water in the midst of this Archipelago of Islands, in advancing to the southward. Our soundings were from 55 to 75 and 80 fathom, grey sand, ooze, and rotten shells. When we were entirely out of the channel, we sounded and found no bottom. We then steered S. W.

Pass the line a fifth time.

The 26th, at break of day, we discovered an island, bearing S. S. W. and a little after another bearing W. N. W. At noon we saw no more of the labyrinth of islands we had left, and the meridian altitude gave us 00° 23′ south latitude. This was the fifth time of our passing the line. We continued close on a wind, with the larboard tacks on board, and in the afternoon we had sight of a small island in the S. E. The next day, at sun-rise, we saw it somewhat elevated, bearing N. E. about nine or ten leagues distance, seeming to extend N. E. and S. W. about two leagues. A large hummock, very steep, and of a remarkable height, which we named Big Thomas, (Gros Thomas) shewed itself at ten in the forenoon. At its southern point there is a small island, and there are two at the northern one. The currents ceased setting[setting] us to the northward; we had, on the contrary, a difference to the southward. This circumstance, together with our observed latitude, which made us to the southward of Cape Mabo, totally convinced me that we were at length entered into the Archipelago of the Moluccas.

Discussion concerning Cape Mabo.

Let me now ask, which this Cape Mabo is, and where it is situated? Some make it the Cape, which, to the northward, terminates the western part of New Guinea. Dampier and Woods Rogers place it the former, in one of the gulphs of Gilolo in 30′ S. lat. The second, eight leagues at farthest from this great island. But all this part is an extensive Archipelago of little isles; which, on account of their number, were called the Thousand Isles, by admiral Roggewein, who passed through them in 1722. Then in what manner does this Cape Mabo, which is in the neighbourhood of Gilolo, belong to New Guinea? Where shall we place it, if (as there is so much reason to believe) all New Guinea itself is a heap of great islands? the various channels between which are as yet unknown. It must certainly belong to the westmost of these considerable isles.
