On a certain day, not of tempest but of emotion, when old Ocean indulged only in wild and graceful gaieties, I was tranquilly seated upon a beautiful headland of some eighty feet in height, and I enjoyed myself in watching the waves as upon a line of a quarter of a league they rushed in as if to assail my rocky seat, the green crest of each wave rounding and rearing, wave urging wave as though in actual and intelligent racing. Now and then a sea would strike so that my very headland seemed to tremble, and burst as with a thunder clap at my very feet. Advancing, retiring, returning, breaking, the wildly sportive waves were for a long time quite admirably regular in their movements. But on a sudden this regularity was at an end. Some wild cross wave from the west suddenly struck my great regular and hitherto well behaved wave from the south. Such was the crash that in an instant the very sky above me was darkened by the blinding spray; and on my lofty promontory I was covered, not with the many colored and fleeting mist, but with a huge, dark, massive wave, which fell on me, heavy, crushing, and thoroughly saturating. Ah! Just then I should very much have liked the company of those very learned Academicians and ultra positive Engineers, who are so well posted up in the combats of the Ocean, and so very certain that the utmost height of a wave is just twenty feet! No; tranquilly seated in our studies we should _not_ lightly question the veracity of so many bold, hardy, and resolved men, who have looked Death in the face too often to be guilty of the childish vanity of exaggerating the dangers which they have often braved--and are ready to brave again. Nor should we ever oppose the calm narratives of ordinary navigators on the great and well known courses to the animated and often thrilling pictures occasionally presented to us by the bold discoverers who seek the very reefs and shoals which the common herd of sailors so carefully avoid. Cook, Peron, Durville--discoverers such as these incurred very real dangers in the then unfrequented Australian and Coraline seas, compelled as they were to dare the continually shifting sand bank, and the conflicting currents which raise such frightful commotions in the narrow channels.
