All that I can recall of the previous night is the terrible impression made upon me by that moment when the machine, instead of being caught in the vortex of the cataract rose under the impulse of its machinery like a bird with its huge wings beating with tremendous power! So this machine actually fulfilled a four-fold use! It was at the same time automobile, boat, submarine, and airship.

Earth, sea and air,--it could move through all three elements! And with what power! With what speed! Al few instants sufficed to complete its marvelous transformations.

The same engine drove it along all its courses! And I had been a witness of its metamorphoses! But that of which I was still ignorant, and which I could perhaps discover, was the source of the energy which drove the machine, and above all, who was the inspired inventor who, after having created it, in every detail, guided it with so much ability and audacity! At the moment when the "Terror" rose above the Canadian Falls, I was held down against the hatchway of my cabin.

The clear, moonlit evening had permitted me to note the direction taken by the air-ship.
It followed the course of the river and passed the Suspension Bridge three miles below the falls.

It is here that the irresistible rapids of the Niagara River begin, where the river bends sharply to descend toward Lake Ontario.
On leaving this point, I was sure that we had turned toward the east.
The captain continued at the helm.
