On the 8th of October, after a voyage of six-and-sixty days, the "Belle Poule" arrived in James Town harbor; and on its arrival, as on its departure from France, a great firing of guns took place. First, the "Oreste" French brig-of-war began roaring out a salutation to the frigate; then the "Dolphin" English schooner gave her one-and-twenty guns; then the frigate returned the compliment of the "Dolphin" schooner; then she blazed out with one-and-twenty guns more, as a mark of particular politeness to the shore--which kindness the forts acknowledged by similar detonations. These little compliments concluded on both sides, Lieutenant Middlemore, son and aide-de-camp of the Governor of St. Helena, came on board the French frigate, and brought his father's best respects to his Royal Highness. The Governor was at home ill, and forced to keep his room; but he had made his house at James Town ready for Captain Joinville and his suite, and begged that they would make use of it during their stay. On the 9th, H. R. H. the Prince of Joinville put on his full uniform and landed, in company with Generals Bertrand and Gourgaud, Baron Las Cases, M. Marchand, M. Coquereau, the chaplain of the expedition, and M. de Rohan Chabot, who acted as chief mourner. All the garrison were under arms to receive the illustrious Prince and the other members of the expedition--who forthwith repaired to Plantation House, and had a conference with the Governor regarding their mission. On the 10th, 11th, 12th, these conferences continued: the crews of the French ships were permitted to come on shore and see the tomb of Napoleon. Bertrand, Gourgaud, Las Cases wandered about the island and revisited the spots to which they had been partial in the lifetime of the Emperor. The 15th October was fixed on for the day of the exhumation: that day five-and twenty years, the Emperor Napoleon first set his foot upon the island. On the day previous all things had been made ready: the grand coffins and ornaments brought from France, and the articles necessary for the operation were carried to the valley of the Tomb. The operations commenced at midnight. The well-known friends of Napoleon before named and some other attendants of his, the chaplain and his acolytes, the doctor of the "Belle Poule," the captains of the French ships, and Captain Alexander of the Engineers, the English Commissioner, attended the disinterment. His Royal highness Prince de Joinville could not be present because the workmen were under English command. The men worked for nine hours incessantly, when at length the earth was entirely removed from the vault, all the horizontal strata of masonry demolished, and the large slab which covered the place where the stone sarcophagus lay, removed by a crane. This outer coffin of stone was perfect, and could scarcely be said to be damp.
