Besides the sight of flying fish, sharks, dolphins, and other deep-water fish; cape petrels, albatrosses, and other oceanic birds, serve to banish the sameness of a sea voyage, and that ennui which lays its benumbing hand upon those who have but few resources in themselves, and looking for it in objects around, too often feel disappointed. It is usually about the 29° of latitude, and 26° of west longitude, that the gigantic species of albatross is usually first seen, as well as the smaller but not less elegant species of the same bird. At first but few are seen, but they increase in numbers as the vessel gets into more southern latitudes; at some seasons of the year they appear more numerous than at others, which may be attributed to the pairing time, which may keep them, at certain seasons, nearer the rocky islets upon which they breed or rear their young. The large white or wandering albatross,[19] (_Diomedia exulans_,) the type of the genus, excites much interest by its majestic appearance, either when almost sweeping the sides of the vessel with its huge pinions, or when beheld a prisoner on the ship’s deck, realizing the idea of the famed _roc_ (allowing for the brilliant and exaggerated descriptions usual in all eastern nations) mentioned in the Arabian Nights’ Entertainments.[20] It is pleasing to observe this superb bird sailing in the air in graceful and elegant movements, seemingly excited by some invisible power, for there is rarely any movement of the wings seen, after the first and frequent impulses given, when the creature elevates itself in the air; rising and falling as if some concealed power guided its various motions, without any muscular exertion of its own; and then descending sweeps the air close to the stern of the ship, with an independence of manner, as if it were “monarch of all it surveyed.” It is from the very little muscular exertion used by these birds, that they are capable of sustaining such long nights without repose.
