Toward the middle of that month of May the newspapers of Pennsylvania informed their readers of some strange occurrences in different parts of the state. On the roads which radiated from Philadelphia, the chief city, there circulated an extraordinary vehicle, of which no one could describe the form, or the nature, or even the size, so rapidly did it rush past. It was an automobile; all were agreed on that. But as to what motor drove it, only imagination could say; and when the popular imagination is aroused, what limit is there to its hypotheses? At that period the most improved automobiles, whether driven by steam, gasoline, or electricity, could not accomplish much more than sixty miles an hour, a speed that the railroads, with their most rapid expresses, scarce exceed on the best lines of America and Europe. Now, this new automobile which was astonishing the world, traveled at more than double this speed. It is needless to add that such a rate constituted an extreme danger on the highroads, as much so for vehicles, as for pedestrians. This rushing mass, coming like a thunder-bolt, preceded by a formidable rumbling, caused a whirlwind, which tore the branches from the trees along the road, terrified the animals browsing in adjoining fields, and scattered and killed the birds, which could not resist the suction of the tremendous air currents engendered by its passage. And, a bizarre detail to which the newspapers drew particular attention, the surface of the roads was scarcely even scratched by the wheels of the apparition, which left behind it no such ruts as are usually made by heavy vehicles. At most there was a light touch, a mere brushing of the dust. It was only the tremendous speed which raised behind the vehicle such whirlwinds of dust. “It is probable,” commented the New York Herald, “that the extreme rapidity of motion destroys the weight.” 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.
