The lieutenant was in the act of describing to his companions the unsatisfactory nature of the foregoing brief colloquy, when suddenly--_instantaneously_--there occurred an awful pause in the fury of the hurricane; the wind lulled at once to a dead calm; the air cleared; the sea, no longer thrashed down by the gale, reared itself aloft as though it would scale the very heavens; and the canvas of the barque flapped with a single loud thunderous report as she rolled heavily to windward. "Now, look out!" gasped Mildmay. And, even as the words escaped his lips, down came the hurricane again in a sudden mad burst of relentless fury; but _now_ the wind blew from the _northward_, the point of the compass exactly opposite that from which it had been blowing a minute before. The _Flying Fish_, having neither sails nor spars exposed to the blast, received this second stroke of the gale with impunity; but with the devoted barque it was, alas, very different. She was struck flat aback and borne irresistibly over on her beam-ends, gathering stern-way at the same time. The crew, at last fully alive to the extreme peril of their situation, scrambled along the deck and made their way to the braces in a futile attempt to haul round the yards, the helmsman at the same time jamming the wheel hard down that the ship might have a chance to pay off. The yards, however, were jammed fast against the weather rigging, and could not be moved; neither would the ship's head pay off; meanwhile, her stern-way was rapidly increasing, the sea already foaming up level with her taffrail; and presently it curled in over her lee quarter, sweeping in a steadily increasing volume along her deck. The catastrophe which followed took place with startling rapidity. The stern of the barque, now buried beneath the surge, seemed at once to lose all its buoyancy, and, powerfully depressed by the leverage of the topsails on the masts, plunged at once deeply below the surface of the hungrily leaping sea, the rest of the hull following so quickly that, before the horrified spectators in the _Flying Fish's_ pilot-house fully realised what was happening, the entire hull had disappeared, the masts, yards, and top-hamper generally only remaining in sight a moment longer, as though to impress upon them unmistakably the fact that a ship was foundering before their eyes. "Come back and close the door!" thundered Sir Reginald to Mildmay, laying his hand upon certain valve-handles as the lieutenant sprang out on deck, urged by some indefinite purpose of rendering help where help was obviously no longer possible. Mildmay stood for a moment, as one in a dream, watching the submergence of the ill-fated _Mercury's_ jib-boom end and fore-topgallant mast-head (the last of her spars to disappear) beneath the swirl where her hull had just vanished, and then, dazedly, he obeyed the baronet's sharply reiterated command.
