Edison's Conquest of Mars Part 13

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 inst.i.tuted 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 pa.s.s out to a greater or less distance in s.p.a.ce 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 a.s.sumed 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 pa.s.s 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 pa.s.s 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 pa.s.sing 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 pa.s.sage 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 pa.s.sage 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 s.p.a.ce for our mother planet.

CHAPTER NINE

_JOURNEY'S END_

"All aboard!" was the signal, and the squadron having a.s.sembled 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 pa.s.s 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 grat.i.tude 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 a.s.sembled 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 we carried him into our car there was no atmosphere capable of conveying any sounds he might attempt to utter.

It seemed a fair a.s.sumption that the language of the Martians would be scientific in its structure. We had so much evidence of the practical bent of their minds, and of the immense progress which they had made in the direction of the scientific conquest of nature, that it was not to be supposed their medium of communication with one another would be lacking in clearness, or would possess any of the puzzling and unnecessary ambiguities that characterized the languages spoken on the earth.

"We shall not find them making he's and she's of stones, sticks and other inanimate objects," said one of the American linguists. "They must certainly have gotten rid of all that nonsense long ago."

"Ah," said a French Professor from the Sorbonne, one of the makers of the never-to-be-finished dictionary. "It will be like the language of my country. Transparent, similar to the diamond, and sparkling as is the fountain."

"I think," said a German enthusiast, "that it will be a universal language, the Volapuk of Mars, spoken by all the inhabitants of that planet."

"But all these speculations," broke in Mr. Edison, "do not help you much. Why not begin in a practical manner by finding out what the Martian calls himself, for instance."

This seemed a good suggestion, and accordingly several of the bystanders began an expressive pantomime, intended to indicate to the giant, who was following all their motions with his eyes, that they wished to know by what name he called himself. Pointing their fingers to their own breast they repeated, one after the other, the word "man."

If our prisoner had been a stupid savage, of course any such attempt as this to make him understand would have been idle. But it must be remembered that we were dealing with a personage who had presumably inherited from hundreds of generations the results of a civilization, and an intellectual advance, measured by the constant progress of millions of years.

Accordingly we were not very much astonished, when, after a few repet.i.tions of the experiment, the Martian--one of whose arms had been partially released from its bonds in order to give him a little freedom of motion--imitated the action of his interrogators by pressing his finger over his heart.

Then, opening his mouth, he gave utterance to a sound which shook the air of the car like the hoa.r.s.e roar of a lion. He seemed himself surprised by the noise he made, for he had not been used to speak in so dense an atmosphere.

Our ears were deafened and confused, and we recoiled in astonishment, not to say, half in terror.

With an ugly grin distorting his face as if he enjoyed our discomfiture, the Martian repeated the motion and the sound.

"R-r-r-r-r-r-h!"

It was not articulate to our ears and not to be represented by any combination of letters.

"Faith," exclaimed a Dublin University professor, "if that's what they call themselves, how shall we ever translate their names when we come to write the history of the conquest?"

"Whist, mon," replied a professor from the University of Aberdeen, "let us whip the gillravaging villains first, and then we can describe them by any int.i.tulation that may suit our deesposition."

The beginning of our linguistic conquest was certainly not promising, at least if measured by our acquirement of words, but from another point of view it was very gratifying, inasmuch as it was plain that the Martian understood what we were trying to do, and was, for the present, at least, disposed to aid us.
