Naturally there were protests from all sides. It was impossible to permit the mad speed of this apparition which threatened to overthrow and destroy everything in its passage, equipages and people. But how could it be stopped? No one knew to whom the vehicle belonged, nor whence it came, nor whither it went. It was seen but for an instant as it darted forward like a bullet in its dizzy flight. How could one seize a cannon-ball in the air, as it leaped from the mouth of the gun?

I repeat, there was no evidence as to the character of the propelling engine. It left behind it no smoke, no steam, no odor of gasoline, or any other oil. It seemed probable, therefore, that the vehicle ran by electricity, and that its accumulators were of an unknown model, using some unknown fluid.

The public imagination, highly excited, readily accepted every sort of rumor about this mysterious automobile. It was said to be a supernatural car. It was driven by a specter, by one of the chauffeurs of hell, a goblin from another world, a monster escaped from some mythological menagerie, in short, the devil in person, who could defy all human intervention, having at his command invisible and infinite satanic powers.

But even Satan himself had no right to run at such speed over the roads of the United States without a special permit, without a number on his car, and without a regular license. And it was certain that not a single municipality had given him permission to go two hundred miles an hour. Public security demanded that some means be found to unmask the secret of this terrible chauffeur.

Moreover, it was not only Pennsylvania that served as the theater of his sportive eccentricities. The police reported his appearance in other states; in Kentucky near Frankfort; in Ohio near Columbus; in Tennessee near Nashville; in Missouri near Jefferson; and finally in Illinois in the neighborhood of Chicago.

The alarm having been given, it became the duty of the authorities to take steps against this public danger. To arrest or even to halt an apparition moving at such speed was scarcely practicable. A better way would be to erect across the roads solid gateways with which the flying machine must come in contact sooner or later, and be smashed into a thousand pieces.

“Nonsense!” declared the incredulous. “This madman would know well how to circle around such obstructions.”

“And if necessary,” added others, “the machine would leap over the barriers.”

“And if he is indeed the devil, he has, as a former angel, presumably preserved his wings, and so he will take to flight.”

But this last was but the suggestion of foolish old gossips who did not stop to study the matter. For if the King of Hades possessed a pair of wings, why did he obstinately persist in running around on the earth at the risk of crushing his own subjects, when he might more easily have hurled himself through space as free as a bird.
