"Holy Virgin!" he would cry, "suppose we are blown up too? suppose we are engulphed in the ice? suppose it should be vomited up in vast blocks which in falling upon us must crush us to pulp and smash the decks in?"

At one moment he would call himself an idiot for not remaining on the rocks at a distance and watching the explosion, and even make as if to jump off the vessel, then immediately recoil from the idea of setting his foot upon a floor that before he could take ten strides might split into chasms, with hideous uproar under him. At another moment he would run to the companion and descend out of my sight, but reappear after a minute or two wildly shaking his head and swearing that if waiting was insupportable in the daylight, it was ten thousand times worse in the gloom and solitude of the interior.

I was too nervous and expectant myself to be affected by his behaviour; but his dread of the explosion upheaving lumps of ice was sensible enough to determine me to post myself under the cover of the hatch and there await the blast, for it was a stout cover and would certainly screen me from the lighter flying pieces.

It was three or four minutes past the hour and I was looking breathlessly at my watch when the first of the explosions took place. Before the ear could well receive the shock of the blast the whole of the barrels exploded along with some twelve or fourteen parcels. Tassard, who stood beside me, fell on his face, and I believed he had been killed. It was so hellish a thunder that I suppose the blowing up of a first-rate could not make a more frightful roar of noise. A kind of twilight was caused by the rise of the volumes of white smoke out of the ice. The schooner shook with such a convulsion that I was persuaded she had been split. Vast showers of splinters of ice fell as if from the sky, and rained like arrows through the smoke, but if there were any great blocks uphove they did not touch the ship. Meanwhile, the other parcels were exploding in their places sometimes two and three at a time, sending a sort of sickening spasms and throes through the fabric of the vessel, and you heard the most extraordinary grinding noises rising out of the ice all about, as though the mighty rupture of the powder crackled through leagues of the island. I durst not look forth till all the powder had burst, lest I should be struck by some flying piece of ice, but unless the schooner was injured below she was as sound as before, and in the exact same posture, as if afloat in harbour, only that of course her stern lay low with the slope of her bed.

I called to Tassard and he lifted his head.

"Are you hurt?" said I.

"No, no," he answered. "'Tis a Spaniard's trick to fling down to a broadside. Body of St. Joseph, what a furious explosion!" and so saying he crawled into the companion and squatted beside me. "What has it done for us?"

"I don't know yet," said I; "but I believe the schooner is uninjured. That was a powerful shock!" I cried, as a half-dozen of bags blew up together in the crevices deep down.

The thunder and tumult of the rending ice accompanied by the heavy explosions of the gunpowder so dulled the hearing that it was difficult to speak. That the mines had accomplished our end was not yet to be known; but there could not be the least doubt that they had not only occasioned tremendous ruptures low down in the ice, but that the volcanic influence was extending far beyond its first effects by making one split produce another, one weak part give way and create other weaknesses, and so on, all round about us and under our keel, as was clearly to be gathered by the shivering and spasms of the schooner, and by the growls, roars, blasts, and huddle of terrifying sounds which arose from the frozen floor.

It was twenty minutes after the hour at which the mines had been framed to explode when the last parcel burst; but we waited another quarter of an hour to make sure that it was the last, during all which time the growling and roaring noises deep down continued, as if there was a battle of a thousand lions raging in the vaults and hollows underneath. The smoke had been settled away by the wind, and the prospect was clear. We ran below to see to the fire and receive five minutes of heat into our chilled bodies, and then returned to view the scene.
