It is Thomas Roch they were after. I was taken along too because I
happened to return to the pavilion at the critical moment.

At any rate, no matter what happens, no matter who our kidnappers may
be, no matter where we are taken, I shall stick to this resolution: I
will continue to play my role of warder. No one, no! none, can suspect
that Gaydon is Simon Hart, the engineer. There are two advantages in
this: in the first place, they will take no notice of a poor devil
of a warder, and in the second, I may be able to solve the mystery
surrounding this plot and turn my knowledge to profit, if I succeed in
making my escape.

But whither are my thoughts wandering? I must perforce wait till we
arrive at our destination before thinking of escaping. It will be time
enough to bother about that when the occasion presents itself. Until
then the essential is that they remain ignorant as to my identity, and
they cannot, and shall not, know who I am.

I am now certain that we are going through the water. But there is one
thing that puzzles me. It is hot a sailing vessel, neither can it be a
steamer. Yet it is incontestably propelled by some powerful machine.
There are none of the noises, nor is there the trembling that
accompanies the working of steam engines. The movement of the vessel
is more continuous and regular, it is a sort of direct rotation that
is communicated by the motor, whatever the latter may be. No mistake
is possible: the ship is propelled by some special mechanism. But what
is it?

Is it one of those turbines that have been spoken of lately, which,
fitted into a submerged tube, are destined to replace the ordinary
