he pirates would not the less be masters of the island, which they
would ravage at their pleasure, and in time, they would end by having
their revenge on the prisoners in Granite House.

However, one chance yet remained; it was that Bob Harvey, after all,
would not venture his ship into the channel, and that he would keep
outside the islet. He would be still separated from the coast by half a
mile, and at that distance his shot could not be very destructive.

"Never!" repeated Pencroft, "Bob Harvey will never, if he is a good
seaman, enter that channel! He knows well that it would risk the brig,
if the sea got up ever so little! And what would become of him without
his vessel?"

In the meanwhile the brig approached the islet, and it could be seen
that she was endeavoring to make the lower end. The breeze was light,
and as the current had then lost much of its force, Bob Harvey had
absolute command over his vessel.

The route previously followed by the boats had allowed her to
reconnoiter the channel, and she boldly entered it.

The pirate's design was now only too evident; he wished to bring her
broadside to bear on the Chimneys and from there to reply with shell and
ball to the shot which had till then decimated her crew.

Soon the "Speedy" reached the point of the islet; she rounded it with
ease; the mainsail was braced up, and the brig hugging the wind, stood
across the mouth of the Mercy.

"The scoundrels! they are coming!" said Pencroft.

At that moment, Cyrus Harding, Ayrton, the sailor, and Herbert, were
rejoined by Neb and Gideon Spilett.

The reporter and his companion had judged it best to abandon the post at
the Mercy, from which they could do nothing against the ship, and they
had acted wisely. It was better that the colonists should be together at
the moment when they were about to engage in a decisive action. Gideon
Spilett and Neb had arrived by dodging behind the rocks, though not
without attracting a shower of bullets, which had not, however, reached
them.

"Spilett! Neb!" cried the engineer. "You are not wounded?"

"No," answered the reporter, "a few bruises only from the ricochet! But
that cursed brig has entered the channel!"

"Yes," replied Pencroft, "and in ten minutes she will have anchored
before Granite House!"

"Have you formed any plan, Cyrus?" asked the reporter.

"We must take refuge in Granite House while there is still time, and the
convicts cannot see us."

"That is, my
