For the fourth piece Cyrus Harding slightly increased the charge, so as to try its extreme range. Then, all standing aside for fear of its bursting, the match was lighted by means of a long cord.

A tremendous report was heard, but the piece had held good, and the colonists rushing to the windows, saw the shot graze the rocks of Mandible Cape, nearly five miles from Granite House, and disappear in Shark Gulf.

“Well, captain,” exclaimed Pencroft, whose cheers might have rivaled the reports themselves, “what do you say of our battery? All the pirates in the Pacific have only to present themselves before Granite House! Not one can land there now without our permission!”

“Believe me, Pencroft,” replied the engineer, “it would be better not to have to make the experiment.”

“Well,” said the sailor, “what ought to be done with regard to those six villains who are roaming about the island? Are we to leave them to overrun our forests, our fields, our plantations? These pirates are regular jaguars, and it seems to me we ought not to hesitate to treat them as such! What do you think, Ayrton?” added Pencroft, turning to his companion.

Ayrton hesitated at first to reply, and Cyrus Harding regretted that Pencroft had so thoughtlessly put this question. And he was much moved when Ayrton replied in a humble tone,—

“I have been one of those jaguars, Mr. Pencroft. I have no right to speak.”

And with a slow step he walked away.

Pencroft understood.

“What a brute I am!” he exclaimed. “Poor Ayrton! He has as much right to speak here as any one!”
