the services it could render to humanity.

Soon the "Albatross" rose again to a moderate height, and passing
over Whydah lost to view this savage coast which the southwest wind
hems round with an inaccessible surf. And she flew out over the
Atlantic.

Chapter XVI

OVER THE ATLANTIC

Yes, the Atlantic! The fears of the two colleagues were realized; but
it did not seem as though Robur had the least anxiety about venturing
over this vast ocean. Both he and his men seemed quite unconcerned
about it and had gone back to their stations.

Whither was the "Albatross" bound? Was she going more than round the
world as Robur had said? Even if she were, the voyage must end
somewhere. That Robur spent his life in the air on board the aeronef
and never came to the ground was impossible. How could he make up his
stock of provisions and the materials required for working his
machines? He must have some retreat, some harbor of refuge--in some
unknown and inaccessible spot where the "Albatross" could revictual.
That he had broken off all connections with the inhabitants of the
land might be true, but with every point on the surface of the earth,
certainly not.

That being the case, where was this point? How had the engineer come
to choose it? Was he expected by a little colony of which he was the
chief? Could he there find a new crew?

What means had he that he should be able to build so costly a vessel
as the "Albatross" and keep her building secret? It is true his
living was not expensive. But, finally, who was this Robur? Where did
he come from? What had been his history? Here were riddles impossible
to solve; and Robur was not the man to assist willingly in their
solution.

It is not to be wondered at that these insoluble problems drove the
colleagues almost to frenzy. To find themselves whipped off into the
unknown without knowing what the end might be doubting even if the
adventure would end, sentenced to perpetual aviation, was this not
enough to drive the President and secretary of the Weldon Institute
to extremities?

Meanwhile the "Albatross" drove along above the Atlantic, and in the
morning when the sun rose there was nothing to be seen but the
circular line where earth met sky. Not a spot of land was insight in
this huge field of vision. Africa had vanished beneath the northern
horizon.

When Frycollin ventured out of his cabin and saw all this water
beneath him, fear took possession of
