current being already
weakened, it would be easy for the brig to advance. But as to entering
the channel, Pencroft, contrary to Ayrton's opinion, could not believe
that she would dare to attempt it.

In the meanwhile, the pirates who occupied the islet had gradually
advanced to the opposite shore, and were now only separated from the
mainland by the channel.

Being armed with muskets alone, they could do no harm to the settlers,
in ambush at the Chimneys and the mouth of the Mercy; but, not knowing
the latter to be supplied with long-range rifles, they on their side did
not believe themselves to be exposed. Quite uncovered, therefore, they
surveyed the islet, and examined the shore.

Their illusion was of short duration. Ayrton's and Gideon Spilett's
rifles then spoke, and no doubt imparted some very disagreeable
intelligence to two of the convicts, for they fell backwards.

Then there was a general helter-skelter. The ten others, not even
stopping to pick up their dead or wounded companions, fled to the other
side of the islet, tumbled into the boat which had brought them, and
pulled away with all their strength.

"Eight less!" exclaimed Pencroft. "Really, one would have thought that
Mr. Spilett and Ayrton had given the word to fire together!"

"Gentlemen," said Ayrton, as he reloaded his gun, "this is becoming more
serious. The brig is making sail!"

"The anchor is weighed!" exclaimed Pencroft.

"Yes, and she is already moving."

In fact, they could distinctly hear the creaking of the windlass. The
"Speedy" was at first held by her anchor; then, when that had been
raised, she began to drift towards the shore. The wind was blowing
from the sea; the jib and the foretopsail were hoisted, and the vessel
gradually approached the island.

From the two posts of the Mercy and the Chimneys they watched her
without giving a sign of life, but not without some emotion. What
could be more terrible for the colonists than to be exposed, at a short
distance, to the brig's guns, without being able to reply with any
effect? How could they then prevent the pirates from landing?

Cyrus Harding felt this strongly, and he asked himself what it would
be possible to do. Before long, he would be called upon for his
determination. But what was it to be? To shut themselves up in Granite
House, to be besieged there, to remain there for weeks, for months even,
since they had an abundance of provisions? So far good! But after that?
