George then sprang into the mizzen-rigging and looked anxiously out over the glittering surface of the sea, in the effort to catch a glimpse of the man, should he happen to be still above water. It was not, however, until the _Aurora_ was fairly crossing the wake of the burning ship-- which by this time had drifted a considerable distance to leeward--that he was successful. Then, indeed, he did for an instant detect a small dark object on the crest of a sea, standing out in bold relief against the bright ruddy reflection of the flames in the water beyond it. Almost at the instant that he caught sight of it, he lost it again as it disappeared in the hollow of the swell, then once more it rose into view, clearly and unmistakably the head of a man. "All right, I see him," he exclaimed. "Now then, Mr Bowen, is the boat ready? I am going to that poor fellow's assistance, so back the main-topsail, if you please, and send the boat after us as quickly as you can." As the last words left George's mouth his hands rose above his head, his body curved itself over towards the water, and in an instant he shot downward out of the rigging swiftly as a sea-bird making its swoop, and entered the water without a splash. On coming to the surface, Captain Leicester struck vigorously out at once in the direction of the burning ship, knowing that the man he sought was exactly in line with her, but that he would probably not see him until he was close upon him. He swam steadily on, not hurrying himself, but husbanding his strength as much as possible, and in about ten minutes he caught sight of the object of which he was in search. But the manner in which that object presented itself to his view was so startling that George's first impulse was to turn round and swim back towards the _Aurora_ with all speed, an impulse which, however, was only felt to be instantly overcome. The man was suddenly revealed, within some six feet or so of George's grasp, as the latter rose upon the crest of a sea; but, instead of swimming as George expected he would be, the unfortunate creature was lying on his back, his ghastly white face upturned to the sky, and his eyes fixed and staring, with that terrible indescribable expression in them which tells at once and unmistakably the dreadful tale of _madness_. Very naturally, our hero felt a little doubtful as to the expediency of placing himself within the grasp of a madman; he therefore, before closing with him, exclaimed in a loud, cheery voice-- "Hillo, there! are you tired? If so, just say the word, and I'll drop alongside and lend you a hand." For all the visible effect this speech had on the stranger he might as well have been stone-deaf, for he vouchsafed not the slightest notice.
