On the afternoon of the following day, (25th,) we sailed from St. Helena, and experienced between that island and Ascension a light trade-wind, which would occasionally freshen for a short period. Early on the morning of the 4th of March, the _Island of Ascension_ was seen, bearing north-west-half-west, by compass distant about twenty-five miles.[87] Our course was steered, so as to pass close to the settlement. The appearance of the island is sterile in the extreme, seeming only calculated for the habitation of the numerous oceanic birds which hovered about the ship in great numbers. Volcanic rocks, in rugged and mis-shapen masses, terminating in abrupt precipices, or shelving declivities, form the principal feature of the island. And when the clouds which enveloped the Green Mountain passed away, its verdant character contrasted in a very beautiful manner with the sterile rocks and mountains, red with the _tufa_, or volcanic ash, beneath. Some little white habitations, perched on the ledge of one part of the lofty eminence, and distinctly seen from the ship, had a very pretty and pleasing effect, as a bright sun diffused its rays over the scene, which for some time remained clear from even a passing cloud. A number of gannets were busily engaged in fishing, and, from the shoals of flying-fish about, must have enjoyed excellent sport. The frigate birds, (_Trachypetes aquila_, Vieill.) on the contrary, hovered over the vessel, viewing with curiosity the expanded sails and progressive motion of the ship, “walking the waters like a thing of life,” regarding it, with their usual indolence and aristocracy of manner, instead of fishing like the other industrious birds about them. From all the frigate-birds having white abdomens, and being deficient in the red pouch, I presume they were females. The bills of the whole of those about the ship were of a dirty white colour, although described in several works of natural history as red. On a former voyage, a female of the man-of-war hawk (_Trachypetes aquila_) was shot off this island from the deck of the ship, from the numbers which hovered over the vessel. The bird, when struck by the shot, made for the land; but soon after, as if feeling that it would be unable to reach it, returned, with a wavering flight, towards the ship, and we felt confident that she would come on board; approaching the ship, her flight became lower and more unsteady, until she fell dead into the water, quite close to the ship, near the mizen chains, just as we were in expectation that she would have fallen upon the poop.
