cover the mouth of the outlet, now that
it is hidden under reeds and grass, and consequently it would be
impossible for them to penetrate into Granite House."

"But our plantations, our poultry-yard, our corral, all, everything!"
exclaimed Pencroft, stamping his foot. "They may spoil everything,
destroy everything in a few hours!"

"Everything, Pencroft," answered Harding, "and we have no means of
preventing them."

"Are they numerous? that is the question," said the reporter. "If they
are not more than a dozen, we shall be able to stop them, but forty,
fifty, more perhaps!"

"Captain Harding," then said Ayrton, advancing towards the engineer,
"will you give me leave."

"For what, my friend?"

"To go to that vessel to find out the strength of her crew."

"But Ayrton--" answered the engineer, hesitating, "you will risk your

"You mistrust me!" said Ayrton quickly.

Then more humbly,--

"Alas!"

"No! no!" exclaimed Harding with animation, "no, Ayrton, Pencroft does
not mistrust you. You interpret his words wrongly."

"Indeed," returned the sailor, "I only propose to accompany Ayrton as
far as the islet. It may be, although it is scarcely possible, that one
of these villains has landed, and in that case two men will not be too
many to hinder him from giving the alarm. I will wait for Ayrton on the
islet, and he shall go alone to the vessel, since he has proposed to do
so." These things agreed to, Ayrton made preparations for his
departure. His plan was bold, but it might succeed, thanks to the
darkness of the night. Once arrived at the vessel's side, Ayrton,
holding onto the main-chains, might reconnoitre the number and perhaps
