This ball belonged to the lighthouse-tower erected on the highest peak of the Casquettes, a terrible group of rocks jutting out into the Channel, just off the French coast hard by Alderney, some six miles to the north-west of which island they lie. Rocks that are cruel and relentless as the surges that sweep over them in stormy weather, and which are so quaintly named from their helmet, or "casque"-like resemblance--rocks, concerning which the poet Swinburne has sung in his eloquent verse, that breathes the very spirit of the sea in depicting the strife of the elements: "From the depths of the waters that lighten and darken, With change everlasting of life and of death, Where hardly by morn if the lulled ear hearken It hears the sea's as a tired child's breath, Where hardly by night, if an eye dare scan it, The storm lets shipwreck be seen or heard, As the reefs to the waves and the foam to the granite Respond one merciless word. "Sheer seen and far, in the sea's life heaven, A sea-mew's flight from the wild sweet land, White plumed with foam, if the wind wake, seven Black helms, as of warriors that stir, not stand, From the depths that abide and the waves that environ Seven rocks rear heads that the midnight masks; And the strokes of the swords of the storm are as iron On the steel of the wave-worn casques. "Be night's dark word as the word of a wizard, Be the word of dawn as a god's glad word, Like heads of the spirits of darkness visored That see not for ever, nor ever have heard, These basnets, plumed as for fight or plumeless, Crowned by the storm and by storm discrowned, Keep word of the lists where the dead lie tombless And the tale of them is not found!" Hither the boat had drifted in the course of the three days that had elapsed since she had been first becalmed off Spithead, or rather between the Nab and Warner lights; for, it was then that the wind had dropped, leaving her at the mercy of the stream, going whither the current willed. She had pursued a most erratic course, however, to reach this point. To commence with, she had floated on the ebb-tide, which for two hours after high-water runs south by west, out into the Channel past the Isle of Wight; the wind, slight as it was, that subsequently sprung up from the eastward, to which point it had veered after the sea-fog had risen, combined with the westward action of the tideway, making the little vessel take almost a straight course across the stream of the current towards the French coast. When about midway, however, she got into a second channel current, which swept her nearer and nearer to Cape La Hogue. Then, again, when still some miles out from the land, yet another current took charge of her, bringing her within the influence of the strong indraught which runs into the Gulf of Saint Malo; by which, finally, she was wafted, in a circular way, up to "the Caskets," or "Casquettes," to adopt the proper French version.
