But the most alarming circumstance, and what, without the providential interposition of very improbable events, had rendered all their schemes abortive, remains yet to be related. The general idea of the fabric and equipment of the vessel was settled in a few days, and when this was done, it was not difficult to make some estimation of the time necessary to complete her.

These reflections led them to the disheartening discovery, that there was neither compass nor quadrant on the island. Indeed, the commodore had brought a pocket compass on shore for his own use, but Lieutenant Brett had borrowed it to determine the position of the neighbouring islands, and he had been driven to sea in the Centurion, without returning it; and as to a quadrant, that could not be expected to be found on shore, for as it was of no use at land, there could be no reason for bringing it from on board the ship.
