Sir,—The accompanying narrative was originally sent from the Sandwich Islands in the shape of a letter. Since my return to England, it has been suggested to me that it would suit your pages. If you think so, I shall be happy to place it at your disposal. The ground-plan annexed is intended merely to assist the description: it has no pretensions to strict accuracy, the distances have been estimated, not measured.—I remain, Sir, your obedient servant,
