It was a moment of intense excitement. The Professor was watching the hand of the chronometer.
"Five minutes more!" he said. "Four! Three!"
My pulse beat half-seconds.
"Two! One! Down, granite rocks; down with you."
What took place at that moment? I believe I did not hear the dull roar of the explosion. But the rocks suddenly assumed a new arrangement: they rent asunder like a curtain. I saw a bottomless pit open on the shore. The sea, lashed into sudden fury, rose up in an enormous billow, on the ridge of which the unhappy raft was uplifted bodily in the air with all its crew and cargo.
We all three fell down flat. In less than a second we were in deep, unfathomable darkness. Then I felt as if not only myself but the raft also had no support beneath. I thought it was sinking; but it was not so. I wanted to speak to my uncle, but the roaring of the waves prevented him from hearing even the sound of my voice.
In spite of darkness, noise, astonishment, and terror, I then understood what had taken place.
On the other side of the blown-up rock was an abyss. The explosion had caused a kind of earthquake in this fissured and abysmal region; a great gulf had opened; and the sea, now changed into a torrent, was hurrying us along into it.
I gave myself up for lost.
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.
