Hours passed away, hours of dread, for from time to time the hull of the cutter seemed to be struck from below, vibrating through every timber as earthquake shock after shock was felt. Fearful booming sounds were heard from the island telling them where it lay, and again and again there were thunderous crashes, as if the whole of the vast globe were being crumpled up, and the end of all things was at hand.

But in spite of all this, as from being quiescent the sea heaved, and the cutter was tossed here and there like a cork in some torrent, not a gleam of light came to her occupants, neither the glow of the eruption nor the rays from the sun. It must have been day for many hours, but all around was a breathless calm, and the dense black cloud grew thicker, and they could feel that the deck of the cutter was thick with a soft powdery ash.

The anxiety of all was so great, the care induced by their position so terrible, that no attempt was made to obtain food or water till quite twenty-four hours must have passed, and then, utterly worn out with the awful explosions, as of a cannonade going on, one by one all fell asleep, save the captain and Mark, who sat there in the darkness talking in whispers, and listening to the distant sounds.

“We are drifting slowly in some current, Mark,” said the captain at last.

“How do you know, father?”

“The reports are more distant. If we could but have light once more.”

It was a weary time before the captain’s desire was granted, and the first harbingers of that coming light were forty-eight hours after the first embarkation in the cutter. They came in the shape of a pleasant cool breeze which it was delicious to breathe, and by slow degrees there was first a faint light, then a glow as if the glare of the burning mountains were shining through, and then a joyful shout of thankfulness arose from officers and crew, for the light was from the rising sun, and they could see blue dancing water, and then, with one bound, they were in broad day, with a great black curtain riding slowly away from them across the sea.

Away south of the sun there was a huge black mountain of vapour quite twenty miles away, and evidently covering the island, while the cutter was drifting slowly farther and farther away in the light current in which she had been caught.

As for those on board, after they had each in his own way, and then collectively at the captain’s wish, returned thanks for their preservation, the first thing to be done was to remove the blackening ashes from their faces, while Jimpny swept pretty well half a ton of the curious volcanic dust from the cutter’s decks.

“What now?” said the major. “Back to the island to see what damage has been done?”
