An hour passed away--two hours, perhaps--I cannot tell. We clutched each other fast, to save ourselves from being thrown off the raft. We felt violent shocks whenever we were borne heavily against the craggy projections. Yet these shocks were not very frequent, from which I concluded that the gully was widening. It was no doubt the same road that Saknussemm had taken; but instead of walking peaceably down it, as he had done, we were carrying a whole sea along with us. These ideas, it will be understood, presented themselves to my mind in a vague and undetermined form. I had difficulty in associating any ideas together during this headlong race, which seemed like a vertical descent. To judge by the air which was whistling past me and made a whizzing in my ears, we were moving faster than the fastest express trains. To light a torch under these conditions would have been impossible; and our last electric apparatus had been shattered by the force of the explosion. I was therefore much surprised to see a clear light shining near me. It lighted up the calm and unmoved countenance of Hans. The skilful huntsman had succeeded in lighting the lantern; and although it flickered so much as to threaten to go out, it threw a fitful light across the awful darkness. I was right in my supposition. It was a wide gallery. The dim light could not show us both its walls at once. The fall of the waters which were carrying us away exceeded that of the swiftest rapids in American rivers. Its surface seemed composed of a sheaf of arrows hurled with inconceivable force; I cannot convey my impressions by a better comparison. The raft, occasionally seized by an eddy, spun round as it still flew along. When it approached the walls of the gallery I threw on them the light of the lantern, and I could judge somewhat of the velocity of our speed by noticing how the jagged projections of the rocks spun into endless ribbons and bands, so that we seemed confined within a network of shifting lines. I supposed we were running at the rate of thirty leagues an hour. My uncle and I gazed on each other with haggard eyes, clinging to the stump of the mast, which had snapped asunder at the first shock of our great catastrophe. We kept our backs to the wind, not to be stifled by the rapidity of a movement which no human power could check. Hours passed away. No change in our situation; but a discovery came to complicate matters and make them worse.
