On the 22d of May, two isles were observed, the most southerly bearing from S. by E. to S.W. by S., and seeming to be about twelve leagues long, in a N.N.W. direction; the other bore from S.W. 1/2 S. to W.N.W., and having been first seen at day-break, was called Aurora.  To the former, in honour of the day, was given the name of Isle de la Pentecote, or Whitsun Isle.  Bougainville attempted to pass betwixt these two islands, but the wind failing him, he was obliged to go to leeward of Aurora.  In getting to the northward, along its eastern shore, he saw a little isle, rising like a sugar-loaf and bearing N. by W. which he denominated Peak of the Etoile.  He now ranged along the Isle of Aurora, at about a league and a half distant.  It is described as about ten leagues in length, but not more than two in breadth, with steep shores, and as covered with wood.  At two in the afternoon, when coasting this isle, the summits of high mountains were perceived over it, about ten leagues off, which belonged to another island, as was found next morning.  This island lay S.W. of Aurora, and at the nearest part was about three or four leagues from it.  Several canoes were seen along its coasts, but none of the natives put off to the ships.  Though no bottom could be found near the shore with fifty fathom, yet Bougainville resolved, if possible, to make a landing on it, in order to get wood and necessary refreshments.  A party of men was accordingly sent off in three armed boats; and effected a landing without any opposition.  Bougainville himself and some others went to join this party in the afternoon, and found it busily employed as directed, the natives lending considerable assistance by conveying wood, &c. to the boats.  At first, indeed, they presented themselves in an armed posture, and seemed resolved to prevent any intrusion on their ground, but the prudent and conciliatory conduct of the officers effected a relinquishment of immediate hostility.  This, it is thought, was but deceitful, and apparently intended to throw the party off its guard.  Very probably, they meditated a serious attack, but were disconcerted by the party embarking sooner than they expected.  In doing so, they exhibited what had continued to actuate them, for when the party put off in their boats, these people followed it, and showed their dexterity in throwing stones and arrows, from which they did not desist, till twice fired on by the crew.  These savages are unfavourably described; they are said to have been ugly, of short stature, and ill proportioned; and as they were affected with a disease which Bougainville considered leprosy, this island got the name of Isle of Lepers.  The few women that were seen, at best rivalled the men in disagreeable appearance, and were about as naked.
