“It is there that they have been struck!” said Cyrus Harding.

“But with what weapon?” cried the reporter.

“A weapon, lightning-like in its effects, and of which we have not the secret!”

“And who has struck the blow?” asked Pencroft.

“The avenging power of the island,” replied Harding, “he who brought you here, Ayrton, whose influence has once more manifested itself, who does for us all that which we cannot do for ourselves, and who, his will accomplished, conceals himself from us.”

“Let us make search for him, then!” exclaimed Pencroft.

“Yes, we will search for him,” answered Harding, “but we shall not discover this powerful being who performs such wonders, until he pleases to call us to him!”

This invisible protection, which rendered their own action unavailing, both irritated and piqued the engineer. The relative inferiority which it proved was of a nature to wound a haughty spirit. A generosity evinced in such a manner as to elude all tokens of gratitude, implied a sort of disdain for those on whom the obligation was conferred, which in Cyrus Harding’s eyes marred, in some degree, the worth of the benefit.

“Let us search,” he resumed, “and God grant that we may some day be permitted to prove to this haughty protector that he has not to deal with ungrateful people! What would I not give could we repay him, by rendering him in our turn, although at the price of our lives, some signal service!”

From this day, the thoughts of the inhabitants of Lincoln Island were solely occupied with the intended search. Everything incited them to discover the answer to this enigma, an answer which would only be the name of a man endowed with a truly inexplicable, and in some degree superhuman power.
