, but immediately rose and hurried out.

All the pirates were making for the passage, in front of which were
Ker Karraje, Engineer Serko, Captain Spade, Boatswain Effrondat,
Engine-driver Gibson and the Count d'Artigas' big Malay attendant.

I soon learn the reason for the tumult, for the sentries rush in with
shouts of alarm.

Several vessels have been sighted to the northwest--warships steaming
at full speed in the direction of Back Cup.

CHAPTER XVI.

ONLY A FEW MORE HOURS.

What effect this news has upon me, and what emotion it awakens within
my soul! The end, I feel, is at hand. May it be such as civilization
and humanity are entitled to.

Up to the present I have indited my notes day by day. Henceforward
it is imperative that I should inscribe them hour by hour, minute by
minute. Who knows but what Thomas Roch's last secret may be revealed
to me and that I shall have time to commit it to paper! Should I die
during the attack God grant that the account of the five months I have
passed in Back Cup may be found upon my body!

At first Ker Karraje, Engineer Serko, Captain Spade, and several of
their companions took up position on the exterior base of the island.
What would I not give to be able follow to them, and in the friendly

An hour later they return after having left a score of men to keep

will attempt a night attack and land a storming party, for they must
imagine that the place is in a thorough condition of defence.

All night long the pirates work, installing the trestles at different
points of the coast. Six have been taken through the passage to places
selected in advance.

This done, Engineer Serko joins Thomas Roch in his laboratory. Is he
going to tell him what is passing, that a squadron is in view of Back
Cup, and that his fulgurator will be employed to defend the island?

What is certain is that half a hundred engines, each charged with
several pounds of the explosive and of the substance that ensures a
trajectory superior to that of any other projectile, are ready for
their work of destruction.

As to the deflagrator liquid, Thomas Roch has a certain number of
phials of it, and--I know only too well--will not refuse to help Ker
Karraje's pirates with it.

During these preparations night has c
