Edison's Conquest of Mars by Garrett Putman Serviss (good books for 8th graders TXT) 📕

One thing that lends a peculiar horror to a terrestrial battlefield was absent; there was no bloodshed. The vibratory energy, not only completely destroyed whatever it fell upon but it seared the veins and arteries of the dismembered bodies so that there was no sanguinary exhibition connected with its murderous work.

All this time the shackled Martian had lain on his back where we had left him bound. What his feeling must have been may be imagined. At times, I caught a glimpse of his eyes, wildly rolling and exhibiting, when he saw that the victory was in our hands, the first indications of fear and terror shaking his soul that had yet appeared.

"That fellow is afraid at last," I said to Mr. Edison.

"Well, I should think he ought to be afraid," was the reply.

"So he ought, but if I am not mistaken this fear of his may be the beginning of a new discovery for us."

"How so?" asked Mr. Edison.

"In this way. When once he fears our power, and perceives that there would be no hope of contending against us, even if he were at liberty, he will respect us. This change in his mental attitude may tend to make him communicative. I do not see why we should despair of learning his language from him, and having done that, he will serve as our guide and interpreter, and will be of incalculable advantage to us when we have arrived at Mars."

"Capital! Capital!" said Mr. Edison. "We must concentrate the linguistic genius of our company upon that problem at once."

In the meantime some of the skulkers whose flight I have referred to began to return, crestfallen, but rejoicing in the disappearance of the danger. Several of them, I am ashamed to say, had been army officers. Yet possibly some excuse could be made for the terror by which they had been overcome. No man has a right to hold his fellow beings to account for the line of conduct they may pursue under circumstances which are not only entirely unexampled in their experience, but almost beyond the power of the imagination to picture.

Paralyzing terror had evidently seized them with the sudden comprehension of the unprecedented singularity of their situation. Millions of miles away from the earth, confronted on an asteroid by these diabolical monsters from a maleficent planet, who were on the point of destroying them with a strange torment of death—perhaps it was really more than human nature, deprived of the support of human surroundings, could be expected to bear.

Those who, as already described, had run with so great a speed that they were projected, all unwilling, into space, rising in elliptical orbits from the surface of the planet, describing great curves in what might be denominated its sky, and then coming back again to the little globe on another side, were so filled with the wonders of their remarkable adventure that they had almost forgotten the terror which had inspired it.

There was nothing surprising in what had occurred to them the moment one considered the laws of gravitation on the asteroid, but their stories aroused an intense interest among all who listened to them.

Lord Kelvin was particularly interested, and while Mr. Edison was hastening preparations to quit the asteroid and resume our voyage to Mars, Lord Kelvin and a number of other scientific men instituted a series of remarkable experiments.

It was one of the most laughable things imaginable to see Lord Kelvin, dressed in his air-tight suit, making tremendous jumps in empty space. It reminded me forcibly of what Lord Kelvin, then plain William Thompson, and Professor Blackburn had done when spending a summer vacation at the seaside, while they were undergraduates of Cambridge University. They had spent all their time, to the surprise of onlookers, in spinning rounded stones on the beach, their object being to obtain a practical solution of the mathematical problem of "precession."

Immediately Lord Kelvin was imitated by a dozen others. With what seemed very slight effort they projected themselves straight upwards, rising to a height of four hundred feet or more, and then slowly settling back again to the surface of the asteroid. The time of rise and fall combined was between three and four minutes.

On this little planet the acceleration of gravity or the velocity acquired by a falling body in one second was only four-fifths of an inch. A body required an entire minute to fall a distance of only 120 feet. Consequently, it was more like gradually settling than falling. The figures of these men of science, rising and sinking in this manner, appeared like so many gigantic marionettes bobbing up and down in a pneumatic bottle.

"Let us try that," said Mr. Edison, very much interested in the experiments.

Both of us jumped together. At first, with great swiftness, but gradually losing speed, we rose to an immense height straight from the ground. When we had reached the utmost limit of our flight we seemed to come to rest for a moment, and then began slowly, but with accelerated velocity, to sink back again to the planet. It was not only a peculiar but a delicious sensation, and but for strict orders which were issued that the electrical ships should be immediately prepared for departure, our entire company might have remained for an indefinite period enjoying this new kind of athletic exercise in a world where gravitation had become so humble that it could be trifled with.

While the final preparations for departure were being made, Lord Kelvin instituted other experiments that were no less unique in their results. The experience of those who had taken unpremeditated flights in elliptical orbits when they had run from the vicinity of the Martians suggested the throwing of solid objects in various directions from the surface of the planet in order to determine the distance they would go and the curves they would describe in returning.

For these experiments there was nothing more convenient or abundant than chunks of gold from the Martians' mine. These, accordingly, were hurled in different directions and with every degree of velocity. A little calculation had shown that an initial velocity of thirty feet per second imparted to one of these chunks, moving at right angles to the radius of the asteroid, would, if the resistance of an almost inappreciable atmosphere were neglected, suffice to turn the piece of gold into a little satellite that would describe an orbit around the asteroid, and continue to do so forever, or at least until the slight atmospheric resistance should eventually bring it down to the surface.

But a less velocity than thirty feet per second would cause the golden missile to fly only part way around, while a greater velocity would give it an elliptical instead of a circular orbit, and in this ellipse it would continue to revolve around the asteroid in the character of a satellite.

If the direction of the original impulse were at more than a right angle to the radius of the asteroid, then the flying body would pass out to a greater or less distance in space in an elliptical orbit, eventually coming back again and falling upon the asteroid, but not at the same spot from which it had departed.

So many took part in these singular experiments, which assumed rather the appearance of outdoor sports than of scientific demonstrations, that in a short time we had provided the asteroid with a very large number of little moons, or satellites, of gold, which revolved around it in orbits of various degrees of ellipticity, taking, on the average, about three-quarters of an hour to complete a circuit. Since, on completing a revolution, they must necessarily pass through the point from which they started, they kept us constantly on the qui vive to avoid being knocked over by them as they swept around in their orbits.

Finally the signal was given for all to embark, and with great regret the savants quitted their scientific games, and prepared to return to the electric ships.

Just on the moment of departure, the fact was announced by one, who had been making a little calculation on a bit of paper, that the velocity with which a body must be thrown in order to escape forever the attraction of the asteroid, and to pass on to an infinite distance in any direction, was only about forty-two feet in a second.

Manifestly it would be quite easy to impart such a speed as that to the chunks of gold that we held in our hands.

"Hurrah!" exclaimed one. "Let's send some of this back to the earth."

"Where is the earth?" asked another.

Being appealed to, several astronomers turned their eyes in the direction of the sun, where the black firmament was ablaze with stars, and in a moment recognized the earth-star shining there, with the moon attending close at hand.

"There," said one, "is the earth. Can you throw straight enough to hit it?"

"We'll try," was the reply, and immediately several threw huge golden nuggets in the direction of our far-away world, endeavoring to impart to them at least the required velocity of forty-two feet in a second, which would insure their passing beyond the attraction of the asteroid, and if there should be no disturbance on the way, and the aim were accurate, their eventual arrival upon the earth.

"Here's for you, Old Earth," said one of the throwers, "good luck, and more gold to you!"

If these precious missiles ever reached the earth we knew that they would plunge into the atmosphere like meteors and that probably the heat developed by their passage would melt and dissipate them in golden vapors before they could touch the ground.

Yet there was a chance that some of them—if the aim were true—might survive the fiery passage through the atmosphere and fall upon the surface of our planet where, perhaps, they would afterward be picked up by a prospector and lead him to believe that he had struck a new bonanza.

But until we returned to the earth it would be impossible for us to tell what had become of the golden gifts which we had launched into space for our mother planet.

"All aboard!" was the signal, and the squadron having assembled under the lead of the flagship, we started again for Mars.

This time, as it proved, there was to be no further interruption, and when next we paused it was in the presence of the world inhabited by our enemies, and facing their frowning batteries.

We did not find it so easy to start from the asteroid as it had been to start from the earth; that is to say, we could not so readily generate a very high velocity.

In consequence of the comparatively small size of the asteroid, its electric influence was very much less than that of the earth, and notwithstanding the appliances which we possessed for intensifying the electrical effect, it was not possible to produce a sufficient repulsion to start us off for Mars with anything like the impulse which we had received from the earth on our original departure.

The utmost velocity that we could generate did not exceed three miles in a second, and to get this required our utmost efforts. In fact, it had not seemed possible that we should attain even so great a speed as that. It was far more than we could have expected, and even Mr. Edison was surprised, as well as greatly gratified, when he found that we were moving with the velocity that I have named.

We were still about 6,000,000 miles from Mars, so that, traveling three miles in a second, we should require at least twenty-three days to reach the immediate neighborhood of the planet.

Meanwhile we had plenty of occupation to make the time pass quickly. Our prisoner was transported along with us, and we now began our attempts to ascertain what his language was, and, if possible, to master it ourselves.

Before quitting the asteroid we had found that it was necessary for him to swallow one of his "air pills," as Professor Moissan had called them, at least three times in the course of every twenty-four hours. One of us supplied him regularly and I thought that I could detect evidences of a certain degree of gratitude in his expression. This was encouraging, because it gave additional promise of the possibility of our being able to communicate with him in some more effective way than by mere signs. But once inside the car, where we had a supply of air kept at the ordinary pressure experienced on the earth, he could breathe like the rest of us.

The best linguists in the expedition, as Mr. Edison had suggested, were now assembled in the flagship, where the prisoner was, and they set to work to devise some means of ascertaining the manner in which he was accustomed to express his thoughts. We had not heard him speak, because until
