“Nonsense, Neb,” answered Pencroft, “you did not look at the right moment. An instant before she sank, the brig, as I saw perfectly well, rose on an enormous wave, and fell back on her larboard side. Now, if she had only struck, she would have sunk quietly and gone to the bottom like an honest vessel.”

“It was just because she was not an honest vessel!” returned Neb.

“Well, we shall soon see, Pencroft,” said the engineer.

“We shall soon see,” rejoined the sailor, “but I would wager my head there are no rocks in the channel. Look here, captain, to speak candidly, do you mean to say that there is anything marvelous in the occurrence?”

Cyrus Harding did not answer.

“At any rate,” said Gideon Spilett, “whether rock or explosion, you will agree, Pencroft, that it occurred just in the nick of time!”

“Yes! yes!” replied the sailor, “but that is not the question. I ask Captain Harding if he sees anything supernatural in all this.”

“I cannot say, Pencroft,” said the engineer. “That is all the answer I can make.”

A reply which did not satisfy Pencroft at all. He stuck to “an explosion,” and did not wish to give it up. He would never consent to admit that in that channel, with its fine sandy bed, just like the beach, which he had often crossed at low water, there could be an unknown rock.

And besides, at the time the brig foundered, it was high water, that is to say, there was enough water to carry the vessel clear over any rocks which would not be uncovered at low tide. Therefore, there could not have been a collision. Therefore, the vessel had not struck. So she had blown up.
