How had it happened? who had killed the convicts?  Was it Ayrton?  No, for a moment before he was dreading their return.

But Ayrton was now in a profound stupor, from which it was no longer possible to rouse him.  After uttering those few words he had again become unconscious, and had fallen back motionless on the bed.

The colonists, a prey to a thousand confused thoughts, under the influence of violent excitement, waited all night, without leaving Ayrton’s house, or returning to the spot where lay the bodies of the convicts.  It was very probable that Ayrton would not be able to throw any light on the circumstances under which the bodies had been found, since he himself was not aware that he was in the corral.  But at any rate he would be in a position to give an account of what had taken place before this terrible execution.  The next day Ayrton awoke from his torpor, and his companions cordially manifested all the joy they felt, on seeing him again, almost safe and sound, after a hundred and four days separation.

Ayrton then in a few words recounted what had happened, or, at least, as much as he knew.

The day after his arrival at the corral, on the 10th of last November, at nightfall, he was surprised by the convicts, who had scaled the palisade.  They bound and gagged him; then he was led to a dark cavern, at the foot of Mount Franklin, where the convicts had taken refuge.

His death had been decided upon, and the next day the convicts were about to kill him, when one of them recognized him and called him by the name which he bore in Australia.  The wretches had no scruples as to murdering Ayrton!  They spared Ben Joyce!

But from that moment Ayrton was exposed to the importunities of his former accomplices.  They wished him to join them again, and relied upon his aid to enable them to gain possession of Granite House, to penetrate into that hitherto inaccessible dwelling, and to become masters of the island, after murdering the colonists!

Ayrton remained firm.  The once convict, now repentant and pardoned, would rather die than betray his companions.  Ayrton—­bound, gagged, and closely watched—­lived in this cave for four months.

Nevertheless the convicts had discovered the corral a short time after their arrival in the island, and since then they had subsisted on Ayrton’s stores, but did not live at the corral.

On the 11th of November, two of the villains, surprised by the colonists’ arrival, fired at Herbert, and one of them returned, boasting of having killed one of the inhabitants of the island; but he returned alone.  His companion, as is known, fell by Cyrus Harding’s dagger.

Ayrton’s anxiety and despair may be imagined when he learned the news of Herbert’s death.  The settlers were now only four, and, as it seemed, at the mercy of the convicts.  After this event, and during all the time that the colonists, detained by Herbert’s illness, remained in the corral, the pirates did not leave their cavern, and even after they had pillaged the plateau of Prospect Heights, they did not think it prudent to abandon it.
