that Mont might reach the surface
by climbing up the rocks, although he scarcely dared to hold this
opinion as a certainty.

But when nothing could be seen of him below the surface, he resolved to
look for him above.

Consequently the _Searcher_ rose under his orders, with the happy result
we have described.

CHAPTER XX.

THE WRECKS.

When Mont was fully recovered, the negro Number One announced that they
were going on a long voyage.

"Massa say him start for, um South Pole," he said. "In one hour we be
off, and travel for many week. Travel to the Pole."

In effect, they soon heard the motion of the machinery, and the
_Searcher_ began her long submarine cruise.

For about a week they saw nothing of the captain.

This mysterious man shut himself up and sought intercourse with no one.

Every day, for some hours, the panel in their cabin slid back, and they
enjoyed the treat of looking at the sea lighted by electricity.

The direction of the _Searcher_ was southeast, and she kept at a depth
of a hundred to a hundred and fifty feet.

One day, while the electric ship was stopping to replenish her power, a
curious incident happened.

Stump was looking out of the window, and he suddenly exclaimed:

"What is that, sir?"

Everyone went to examine, and a ship dismantled was seen slowly sinking
to the bottom.

It had foundered a short time before with all hands.

Several men were lashed to the riggings, and their agonized faces
testified to their late sufferings.

A shoal of sharks followed the sinking wreck with distended eyes,
anticipating a feast of human flesh.

As the hull passed the window, Mont read her name, which was the
_Firefly_ of Savannah.

This was not an isolated case, for they frequently saw wrecks, and
remains of wrecks, such as cannons, anchors, chains, and decaying hulls.

"Well, this is a lively existence," exclaimed Mont; "we eat nothing but
fish, and see nothing but fish."

"And wrecks," put in Carl.

A heavy step was heard behind them, and all turned round, to see the
captain.

He placed his hand upon a map, and exclaimed:

"Do you see this island--Malonon? It is where the gallant French
explorer Posterri perished. We are close to it, and, if you please,
gentlemen, you shall land and explore it for yourselves."

This was good news.

"But," said the professor, "if I remember rightly, it is inhabited by
savages."

"Certainly."

"Shall we not be in danger?"

"I
