The Orion was a ship that had been ailing for a long time; in the course of its previous cruises thick layers of barnacles had collected on its keel to such a degree as to deprive it of half its speed; it had gone into the dry dock the year before this, in order to have the barnacles scraped off, then it had put to sea again; but this cleaning had affected the bolts of the keel: in the neighborhood of the Balearic Isles the sides had been strained and had opened; and, as the plating in those days was not of sheet iron, the vessel had sprung a leak. A violent equinoctial gale had come up, which had first staved in a grating and a porthole on the larboard side, and damaged the foretop-gallant-shrouds; in consequence of these injuries, the Orion had run back to Toulon.

It anchored near the Arsenal; it was fully equipped, and repairs were begun. The hull had received no damage on the starboard, but some of the planks had been unnailed here and there, according to custom, to permit of air entering the hold.
