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.
