Next morning, accordingly, they proceeded towards the island. In proportion as they advanced, the noise, increasing in loudness, more and more excited their curiosity; and the sound of the waves, which broke with great violence against the rocks, contributed not a little to swell the deep murmur, the cause of which no one could conjecture. They landed at length amid spray and foam, and, clambering up the cliffs, succeeded with much difficulty in reaching the summit. Here they beheld a sight such, in the opinion of our traveller, as no mortal ever beheld before. There arose in a moment from the surface of the earth an impenetrable cloud, which formed, at the height of forty feet above their heads, a prodigious canopy, or rather sky, of birds of every kind and colour. “Cormorants, sea-swallows, pelicans,--in one word,” says he, “all the winged creatures of Southern Africa were collected, I verily believe, in that spot. The screams of so enormous a multitude of birds mingling together formed an infernal species of music, which seemed to rend the ear with its piercing notes. “The alarm,” he adds, “was so much the greater, among these innumerable legions of birds, in that it was the females with whom we had principally to deal, it being the season of nesting. They had therefore their nests, their eggs, their young ones to defend, and were as fierce as so many harpies. They deafened us with their cries. They stooped upon the wing, and in darting past us, brushed our faces. It was in vain that we fired our pieces; nothing could frighten away this living cloud. We could scarcely take a single step without crushing some eggs or young birds: the earth was covered by them.” They found the caverns and hollows of the rocks inhabited by seals and sea-lions, of the latter of which they killed one specimen of enormous size. The various creeks of the island afforded a retreat to the manchot, a species of penguin, two feet in height, the wings of which, being entirely devoid of feathers, are only used in swimming. On land they hang down by the side of the body in a negligent manner, and communicate to the appearance and air of the bird something peculiarly sinister and funereal. These dismal-looking birds crowded every part of the island, but were nowhere so numerous as about the Dane’s tomb, around which they clustered as if to defend it from violation, and with their startling, melancholy cry, which mingled with the roar of the seal and the sea-lion, gave an air of sadness to the scene which deeply affected the soul. In itself the tomb was rude and simple,--a single block of stone, without name or inscription.
