“Thus our planet pursues its way along its heavenly path, with a speed of more than 100,000 kilometers per hour, and, at the same time, the Sun hurries it on, with all the planets, toward the constellation of Hercules. Recapitulating what has just been said, and allowing for what may have been omitted: it may meet a comet ten or twenty times larger than itself, composed of deleterious gases which would render the atmosphere irrespirable; it may encounter a swarm of uranolites, which would have upon it the effect of a charge of shot upon a meadow lark; it may meet in its path an invisible sun, much larger than itself, whose shock would reduce it to vapor; it may encounter a sun which would consume it in the twinkling of an eye, as a furnace would consume an apple thrown into it; it may be caught in a system of electric forces, which would act like a brake upon its eleven motions, and which would either melt it, or set it afire, like a platinum wire in a strong current; it may lose the oxygen which supports life; it may be blown up like the crust over a crater; it may collapse in some great earthquake; its dry land may disappear, in a second deluge, more universal than the first; it may, on the contrary, lose all its water, an element essential to its organic life; under the attraction of some passing body, it may be detached from the Sun and carried away into the cold of stellar space; it may part, not only with the last vestige of its internal heat, which long since has ceased to have any influence upon its surface, but also with the protecting envelope which maintains the temperature necessary to life; one of these days, when the Sun has grown dark and cold, it may be neither lighted, nor warmed, nor fertilized; on the other hand, it may be suddenly scorched by an outburst of heat, analogous to what has been observed in temporary stars; not to speak of many other sources of accidents and mortal peril, whose easy enumeration we leave to the geologists, paleontologists, meteorologists, physicists, chemists, biologists, physicians, botanists, and even to the veterinary surgeons, inasmuch as the arrival of an army of invisible microbes, if they be but deadly enough, or a well-established epidemic, would suffice to destroy the human race and the principal animal and vegetable species, without working the least harm to the planet itself, from a strictly astronomical point of view.”
Just as the speaker was uttering these last words, a voice, which seemed to come from a distance, fell, as it were, from the ceiling overhead. But a few words of explanation may here perhaps be desirable.
As we have said, the observatories established on the higher mountains of the globe were connected by telephone, with the observatory of Paris, and the sender of the message could be heard at a distance from the receiver, without being obliged to apply any apparatus directly to the ear. The reader doubtless recollects that, at the close of the preceding session, a phonogram from Mt. Gaurisankar stated that a photophonic message, which would be at once deciphered, had been received from the inhabitants of Mars. As the translation of this cipher had not arrived at the opening of the evening session, the bureau of communications had connected the Institute with the observatory by suspending a telephonoscope from the dome of the amphitheater.
The voice from above said:
“The astronomers of the equatorial city of Mars warn the inhabitants of the Earth that the comet is moving directly toward the Earth with a velocity nearly double that of the orbital velocity of Mars. Mechanical motion to be transformed into heat, and heat into electrical energy. Terrible magnetic storms. Move away from Italy.”
The voice ceased amid general silence and consternation. There were, however, a few sceptics left, one of whom, editor of La Libre Critique, raising his monocle to his right eye, had risen from the reporters desk and had exclaimed in a penetrating voice:
“I am afraid that the venerable doctors of the Institute are the victims of a huge joke. No one can ever persuade me that the inhabitants of Mars—admitting that there are any and they have really sent us a warning—know Italy by name. I doubt very much if one of them ever heard of the Commentaries of Caesar or the History of the Popes, especially as—”
The orator, who was launching into an interesting dithyrambus, was at this point suddenly squelched by the turning off of the electric lights. With the exception of the illuminated square in the ceiling, the room was plunged in darkness and the voice
