should the convicts return, or of the precautions to be taken for the
future.

But on this day, while Pencroft watched by the sick-bed, Cyrus Harding
and the reporter consulted as to what it would be best to do.

First of all they examined the corral. There was not a trace of Ayrton.
Had the unhappy man been dragged away by his former accomplices? Had he
resisted, and been overcome in the struggle? This last supposition was
only too probable. Gideon Spilett, at the moment he scaled the palisade,
had clearly seen some one of the convicts running along the southern
spur of Mount Franklin, towards whom Top had sprung. It was one of those
whose object had been so completely defeated by the rocks at the mouth
of the Mercy. Besides, the one killed by Harding, and whose body was
found outside the enclosure, of course belonged to Bob Harvey's crew.

As to the corral, it had not suffered any damage. The gates were closed,
and the animals had not been able to disperse in the forest. Nor could
they see traces of any struggle, any devastation, either in the hut,
or in the palisade. The ammunition only, with which Ayrton had been
supplied, had disappeared with him.

"The unhappy man has been surprised," said Harding, "and as he was a man
to defend himself, he must have been overpowered."

"Yes, that is to be feared!" said the reporter. "Then, doubtless, the
convicts installed themselves in the corral where they found plenty of
everything, and only fled when they saw us coming. It is very evident,
too, that at this moment Ayrton, whether living or dead, is not here!"

"We shall have to beat the forest," said the engineer, "and rid the
island of these wretches. Pencroft's presentiments were not mistaken,
when he wished to hunt them as wild beasts. That would have spared us
all these misfortunes!"

"Yes," answered the reporter, "but now we have the right to be
merciless!"

"At any rate," said the engineer, "we are obliged to wait some time,
and to remain at the corral until we can carry Herbert without danger to
Granite House."

"But Neb?" asked the reporter.

"Neb is in safety."

"But if, uneasy at our absence, he would venture to come?"

"He must not come!" returned Cyrus Harding quickly. "He would be
murdered on the road!"

"It is very probable, however, that he will attempt to rejoin us!"

"Ah, if the telegraph still acted, he might be warned! But that is
impossible now! As to leaving Pencroft and Herbert here alo
