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. I had not addressed a word to him. What good would it do? He would not have answered. I noted that the "Terror" seemed to be guided in its course through the air with surprising ease. Assuredly the roads of the air were as familiar to it as those of the seas and of the lands!

In the presence of such results, could one not understand the enormous pride of this man who proclaimed himself Master of the World? Was he not in control of a machine infinitely superior to any that had ever sprung from the hand of man, and against which men were powerless? In truth, why should he sell this marvel? Why should he accept the millions offered him? Yes, I comprehended now that absolute confidence in himself which was expressed in his every attitude. And where might not his ambition carry him, if by its own excess it mounted some day into madness!

A half hour after the "Terror" soared into the air, I had sunk into complete unconsciousness, without realizing its approach. I repeat, it must have been caused by some drug. Without doubt, our commander did not wish me to know the road he followed.

Hence I cannot say whether the aviator continued his flight through space, or whether the mariner sailed the surface of some sea or lake, or the chauffeur sped across the American roads. No recollection remains with me of what passed during that night of July thirty-first.

Now, what was to follow from this adventure? And especially concerning myself, what would be its end?

I have said that at the moment when I awoke from my strange sleep, the "Terror" seemed to me completely motionless. I could hardly be mistaken; whatever had been her method of progress, I should have felt some movement, even in the air. I lay in my berth in the cabin, where I had been shut in without knowing it, just as I had been on the preceding night which I had passed on board the "Terror" on Lake Erie.

My business now was to learn if I would be allowed to go on deck here where the machine had landed. I attempted to raise the hatchway. It was fastened.

"Ah!" said I, "am I to be kept here until the 'Terror' recommences its travels?" Was not that, indeed, the only time when escape was hopeless?

My impatience and anxiety may be appreciated. I knew not how long this halt might continue.

I had not a quarter of an hour to wait. A noise of bars being removed came to my ear. The hatchway was raised from above. A wave of light and air penetrated my cabin.

With one bound I reached the deck. My eyes in an instant swept round the horizon.

The "Terror," as I had thought, rested quiet on the ground. She was in the midst of a rocky hollow measuring from fifteen to eighteen hundred feet in circumference. A floor of yellow gravel carpeted its entire extent, unrelieved by a single tuft of herbage.

This hollow formed an almost regular oval, with its longer diameter extending north and south. As to the surrounding-wall, what was its height, what the character of its crest, I could not judge. Above us was gathered a fog so heavy, that the rays of the sun had not yet pierced it. Heavy trails of cloud drifted across the sandy floor, Doubtless the morning was still young, and this mist might later be dissolved.

It was quite cold here, although this was the first day of August. I concluded therefore that we must be far in the north, or else high above sea-level. We must still be somewhere on the New Continent; though where, it was impossible to surmise. Yet no matter how rapid our flight had been, the air-ship could not have traversed either ocean in the dozen hours since our departure from Niagara.
