prisoned in that cavern, how do I find myself in the corral?"
"How is it that the convicts are lying yonder dead, in the middle of the enclosure?" answered the engineer.
"Dead!" cried Ayrton, half rising from his bed, notwithstanding his weakness.
His companions supported him. He wished to get up, and with their assistance he did so. They then proceeded together towards the little stream. There, on the bank, in the position in which they had been stricken by death in its most instantaneous form, lay the corpses of the five convicts!
Ayrton was astounded. Harding and his companions looked at him without uttering a word. On a sign from the engineer, Neb and Pencroft examined the bodies, already stiffened by the cold.
They bore no apparent trace of any wound. Only, after carefully examining them, Pencroft found on the forehead of one, on the chest of another, on the back of this one, on the shoulder of that, a little red spot, a sort of scarcely visible bruise, the cause of which they could only conjecture.
"It is there that they have been struck!" said 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 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 marred, in some degree, the worth of the benefit.
