the mechanical
power of the _Nautilus_.

The _Nautilus_ was a masterpiece, containing masterpieces within itself,
and the engineer was struck with astonishment.

The colonists mounted the platform, which rose seven or eight feet above
the water. There they beheld a thick glass lenticular covering, which
protected a kind of large eye, from which flashed forth light. Behind
this eye was apparently a cabin containing the wheels of the rudder, and
in which was stationed the helmsman, when he navigated the _Nautilus_
over the bed of the ocean, which the electric rays would evidently light
up to a considerable distance.

Cyrus Harding and his companions remained for a time silent, for they
were vividly impressed by what they had just seen and heard, and their
hearts were deeply touched by the thought that he whose arm had so often
aided them, the protector whom they had known but a few hours, was at
the point of death.

Whatever might be the judgment pronounced by posterity upon the events
of this, so to speak, extra-human existence, the character of Prince
Dakkar would ever remain as one of those whose memory time can never
efface.

"What a man!" said Pencroft. "Is it possible that he can have lived at
the bottom of the sea? And it seems to me that perhaps he has not found
peace there any more than elsewhere."

"The _Nautilus_," observed Ayrton, "might have enabled us to leave
Lincoln Island and reach some inhabited country."

"Good Heavens!" exclaimed Pencroft, "I for one would never risk myself
in such a craft. To sail on the seas, good; but under the seas, never!"

"I believe, Pencroft," answered the reporter, "that the navigation of a
submarine vessel such as the _Nautilus_ ought to be very easy, and that
we should soon become accustomed to it. There would be no storms, no
lee-shore to fear. At some feet beneath the surface the waters of the
ocean are as calm as those of a lake."

"That may be," replied the sailor, "but I prefer a gale of wind on board
a well-found craft. A vessel is built to sail on the sea, and not
beneath it."

"My friends," said the engineer, "it is useless, at any rate as regards
the _Nautilus_, to discuss the question of submarine vessels. The
_Nautilus_ is not ours, and we have not the right to dispose of it.
Moreover, we could in no case avail ourselves of it. Independently of
the fact that it would be impossible to get it out of this cavern, whose
entrance is now closed by
