have driven Herbert to
despair--killed him perhaps.

"Forward!" said Harding.

The gate of the corral was opened. Jup and Top, who knew when to be
silent, ran in advance. The cart came out, the gate was reclosed, and
the onaga, led by Pencroft, advanced at a slow pace.

Certainly, it would have been safer to have taken a different road than
that which led straight from the corral to Granite House, but the cart
would have met with great difficulties in moving under the trees. It
was necessary, therefore, to follow this way, although it was well-known
to the convicts.

Cyrus Harding and Gideon Spilett walked one on each side of the cart,
ready to answer to any attack. However, it was not probable that the
convicts would have yet left the plateau of Prospect Heights.

Neb's note had evidently been written and sent as soon as the convicts
had shown themselves there. Now, this note was dated six o'clock in the
morning, and the active orang, accustomed to come frequently to the
corral, had taken scarcely three quarters of an hour to cross the five
miles which separated it from Granite House. They would, therefore, be
safe at that time, and if there was any occasion for firing, it would
probably not be until they were in the neighbourhood of Granite House.
However, the colonists kept a strict watch. Top and Jup, the latter
armed with his club, sometimes in front, sometimes beating the wood at
the sides of the road, signalised no danger.

The cart advanced slowly under Pencroft's guidance. It had left the
corral at half-past seven. An hour after four out of the five miles had
been cleared, without any incident having occurred. The road was as
deserted as all that part of the Jacamar Wood which lay between the
Mercy and the lake. There was no occasion for any warning. The wood
appeared as deserted as on the day when the colonists first landed on
the island.

They approached the plateau. Another mile and they would see the bridge
over Creek Glycerine. Cyrus Harding expected to find it in its place;
supposing that the convicts; would have crossed it, and that, after
having passed one of the streams which enclosed the plateau, they would
have taken the precaution to lower it again, so as to keep open a
retreat.

At length an opening in the trees allowed the sea-horizon to be seen.
But the cart continued its progress, for not one of its defenders
thought of abandoning it.

At that moment Pencroft stopped t
