18' S.lat., and 156 deg.

30' E.long., had seen some iron bars and red stuffs used by the natives of these parts.

Dumont d'Urville, much perplexed, and not knowing how to credit the reports of low-class journals, decided to follow Dillon's track.
On the 10th of February, 1828, the Astrolabe appeared off Tikopia, and took as guide and interpreter a deserter found on the island; made his way to Vanikoro, sighted it on the 12th inst., lay among the reefs until the 14th, and not until the 20th did he cast anchor within the barrier in the harbour of Vanou.
On the 23rd, several officers went round the island and brought back some unimportant trifles.

The natives, adopting a system of denials and evasions, refused to take them to the unlucky place.

This ambiguous conduct led them to believe that the natives had ill-treated the castaways, and indeed they seemed to fear that Dumont d'Urville had come to avenge La Perouse and his unfortunate crew.
However, on the 26th, appeased by some presents, and understanding that they had no reprisals to fear, they led M.Jacquireot to the scene of the wreck.
There, in three or four fathoms of water, between the reefs of Pacou and Vanou, lay anchors, cannons, pigs of lead and iron, embedded in the limy concretions.
