When their treasures had been safely conveyed on shore, Harding and his companions agreed to devote some minutes to breakfast. They were almost famished; fortunately, the larder was not far off, and Neb was noted for being an expeditious cook. They breakfasted, therefore, near the Chimneys, and during their repast, as may be supposed, nothing was talked of but the event which had so miraculously saved the colony.

“Miraculous is the word,” repeated Pencroft, “for it must be acknowledged that those rascals blew up just at the right moment! Granite House was beginning to be uncomfortable as a habitation!”

“And can you guess, Pencroft,” asked the reporter, “how it happened, or what can have occasioned the explosion?”

“Oh! Mr. Spilett, nothing is more simple,” answered Pencroft. “A convict vessel is not disciplined like a man-of-war! Convicts are not sailors. Of course the powder-magazine was open, and as they were firing incessantly, some careless or clumsy fellow just blew up the vessel!”

“Captain Harding,” said Herbert, “what astonishes me is that the explosion has not produced more effect. The report was not loud, and besides there are so few planks and timbers torn out. It seems as if the ship had rather foundered than blown up.”

“Does that astonish you, my boy?” asked the engineer.

“Yes, captain.”

“And it astonishes me also, Herbert,” replied he, “but when we visit the hull of the brig, we shall no doubt find the explanation of the matter.”

“Why, captain,” said Pencroft, “you don’t suppose that the ‘Speedy’ simply foundered like a ship which has struck on a rock?”

“Why not,” observed Neb, “if there are rocks in the channel?”
