"And I can visit the celebrated islands where the Boussole and the Astrolabe struck?"

They embarked in the corvettes Boussole and the Astrolabe, neither of which were again heard of.

Dumont d'Urville, commander of the Astrolabe, had then sailed, and two months after Dillon had left Vanikoro he put into Hobart Town.

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.

The large boat and the whaler belonging to the Astrolabe were sent to this place, and, not without some difficulty, their crews hauled up an anchor weighing 1,800 lbs., a brass gun, some pigs of iron, and two copper swivel-guns.
