On our arrival at Oahoo, the Dolphin was out of repair in every respect, and it was indispensably necessary to refit her, before we proceeded further on our return to the coast of Chili or Peru. Whilst the masts were out, and the vessel was undergoing general repairs, the captain received a letter from Captain Edwards, of the ship Loudon, of New-York, stating that he had ran upon a reef, on the Island of Ranai; besides a valuable cargo, he had a large amount of specie and bullion on board. The chief Thunder, (chief of Ranai,) was encouraging the natives of the island to plunder him, and finally, that his life and treasure was in the greatest jeopardy. Although not incumbent upon him as a duty, Captain Percival, with a promptitude highly creditable to himself and the service to which he belonged, chartered a vessel, and with the crew of the Dolphin, and Boque, the Governor of Oahoo, sailed on the same day that he received the letter. He found the situation of Captain Edwards not less critical than he had described it to be. The natives had already plundered him of a part of his cargo, and his own crew was in a state of mutiny. Employing the authority of Chief Boque, and the indefatigable industry of his own crew, Captain Percival caused the stolen goods to be restored, and the cargo and treasure of the Loudon to be safely landed at Oahoo. When all this had been accomplished, Captain Edwards refused to pay the charter of the vessel that was employed for his relief, in consequence of which, a quarrel arose between himself and Captain Percival, that eventuated in consequences injurious and disagreeable to both parties, and after our return home, became a subject of judicial investigation. By this investigation, which was brought on at the instance of Captain Edwards, an opportunity was afforded to Captain Percival and the officers of the Dolphin, to vindicate their characters, which they did, in every instance, to the entire satisfaction of their government and countrymen.
