on the plateau of Prospect
Heights. Harding and Neb proceeded towards the Mercy, and ascended its
left bank without meeting with any trace of the convicts; nor on the
other side of the river, in the depths of the wood, could they perceive
any suspicious indications.

Besides, it might be supposed that in all probability either the
convicts knew of the return of the settlers to Granite House, by having
seen them pass on the road from the corral, or, after the devastation of
the plateau, they had penetrated into Jacamar Wood, following the course
of the Mercy, and were thus ignorant of their return.

In the former case, they must have returned towards the corral, now
without defenders, and which contained valuable stores.

In the latter, they must have regained their encampment, and would wait
on opportunity to recommence the attack.

It was, therefore, possible to prevent them, but any enterprise to clear
the island was now rendered difficult by reason of Herbert's condition.
Indeed, their whole force would have been barely sufficient to cope with
the convicts, and just now no one could leave Granite House.

The engineer and Neb arrived on the plateau. Desolation reigned
everywhere. The fields had been trampled over; the ears of wheat, which
were nearly full-grown, lay on the ground. The other plantations had not
suffered less.

The kitchen-garden was destroyed. Happily, Granite House possessed a
store of seed which would enable them to repair these misfortunes.

As to the wall and buildings of the poultry-yard and the onagers stable,
the fire had destroyed all. A few terrified creatures roamed over the
plateau. The birds, which during the fire had taken refuge on the waters
of the lake, had already returned to their accustomed spot, and were
dabbling on the banks. Everything would have to be reconstructed.

Cyrus Harding's face, which was paler than usual, expressed an internal
anger which he commanded with difficulty, but he did not utter a word.
Once more he looked at his devastated fields, and at the smoke which
still rose from the ruins, then he returned to Granite House.

The following days were the saddest of any that the colonists had passed
on the island! Herbert's weakness visibly increased. It appeared that
a more serious malady, the consequence of the profound physiological
disturbance he had gone through, threatened to declare itself, and
Gideon Spilett feared such an aggravation of his condition t
