"Keeping thus so close an acquaintance with man and all his works, they rejoiced at every success he achieved over the lower forms of life, and grieved at all his failures. Especially were they pained when he tired of the conflict with his natural foe, and began to battle with his own kind. As this inhuman strife continued, the folly and wickedness of it roused to the fullest extent the interest and sympathy of the moon-dwellers, and they began to ask each other what they could do to put a stop to it. They themselves had long since given up war and had even outgrown all individual quarrels, and they could not endure with patience what was then taking place right under their eyes. But they found it easier to declaim against the evil than to suggest any practical method of stopping it. Although so near them in one sense, to the other senses the field of conflict was some two hundred and forty thousand miles away.

"However, of what value is a high state of civilization if it cannot help a neighboring world in such an emergency as this? If they could only communicate in some way with men they could soon make them understand that it would be better for them to cease their fighting and finish their legitimate work of subduing the lower forms of creation.

But how to open communication! The problem long remained unsolved, the condition of things on the earth in the meantime growing worse and worse. At last it was suggested that a shot might be fired which would reach the earth. This was a bold suggestion, but it was well known that they had explosives powerful enough to carry a projectile beyond the moon's attraction, and no one could give any good reason why such a projectile, being entirely free of the moon, should not reach the earth under the power of gravitation. It was determined to try the experiment, and after due preparation, which was comparatively easy with their facilities, an enormous shot was hurled forth. It was large enough to be seen by the aid of their powerful telescopes as it sped on its way, and it was with intense interest that they saw it enter the earth's attraction and finally strike the surface of that globe. Now that so much had been accomplished, they saw immense possibilities before them.

What they now wanted to do was to use their discovery to make men give up their fighting and turn to the arts of peace.

"How could they do this? Some proposed that they should make hollow shot, fill them with Bibles and other books, and bombard the earth with good precepts till men should learn and be tamed. But from their close observation of mankind the moon-dwellers knew they were too uncivilized to get any good from books, and that they certainly could not learn without a teacher. Hence arose the suggestion that missionaries be sent in place of books. As soon as this idea was broached thousands of volunteers offered themselves, and the plan would certainly have been attempted if there had been the slightest possibility that one could live to reach the earth.

"The next proposal came from the medical profession. Long before this time, when the inhabitants of the moon were sometimes governed by their pa.s.sions and before the day of peace and good will had fully arrived, it had been discovered that what was known as the pugnacious instinct was only a disease, bad blood in fact as well as in name, and a remedy had been found for it. This was nothing less than the bi-chloride of comet.

Small comets, such as we call meteorites, were picked up on the surface of the moon and put to this practical use. This medicine, administered as an hypodermic injection, produced wonderful effects, the patient, although afflicted with the most quarrelsome disposition, becoming as mild and harmless as a lamb. However warlike one might be, a few days'

treatment would take the fighting spirit out of him so completely that the mere doubling up his fists and placing them in front of his face would make him feel ill. Peace societies got hold of the remedy and tried it on the soldiers of the standing armies with such success that war had to be abandoned because the men would not fight.

"And now the old recipe was brought out, a large quant.i.ty of the medicine manufactured, and bombs made and filled with it, each one containing full directions for its use written in Volapiik. These were fired to the earth, and, strange to say, the simple language was soon learned, and the moon-dwellers had the satisfaction of seeing men rapidly metamorphosed into a peaceable, friendly race. Thus the moon directly influenced and governed affairs on the earth. Looked at from that distance it seems to have been the most remarkable case of the tail wagging the dog that the earth had ever seen.

"But we may as well relate the sequel. The effect of the treatment lasted only a few hundred years, and as it was the moon's policy never to repeat a cure, men in time became as bad as ever again, and so at last the flood had to come and wipe them off the face of the earth."

CHAPTER XVII

THE DOCTOR IS CONVINCED

As I finished the doctor looked somewhat bored, but Thorwald was kind enough to thank me, and then, at our earnest solicitation, he resumed his argument.

"You have told me," he said, "of some of your earlier beliefs about the origin of meteorites. Have you any more modern views?"

To this the doctor replied: "If my friend here has really finished talking for a while I will say, Thorwald, that the theories already spoken of seem to be disproved by the discovery that these stones enter the earth's atmosphere with a planetary velocity. A body falling from an infinite distance--that is, impelled only by the attraction of gravitation--would strike the earth with a velocity of only six or seven miles a second, while the meteorites come at the rate of twenty to thirty miles a second, the earth's rate of revolution being nineteen miles in the same time. It is found that a necessary consequence of these velocities is that the meteors move about the sun, and not the earth, as the controlling body. Our latest study points to the conclusion that they are of cometary origin, and, as comets have been known to divide, some scientists believe the meteorites are fragments of exploded comets. At any rate, they are found in the company of these mysterious bodies, and appear to have similarly eccentric orbits."

"Your studies are leading you in the right direction," said Thorwald.

"The meteorites do indeed come from the regions of s.p.a.ce, and if they have any story to tell it is a story of those distant parts of the universe about which any testimony is valuable. Let us look again at the fragment we are supposed to hold in our hand. Can we tell of what it is composed, or is its substance something entirely new? I am sure you must have a.n.a.lyzed it down to its minutest particle, and if so you have found it contains nothing foreign to the earth. There is not a single element in the meteorite that does not exist also in the crust of the earth.

Tell me, Doctor, how many elements have you discovered in them?"

"Nearly thirty," answered the doctor. "And one interesting fact is, that the three elements most common in the earth--iron, silicon, and oxygen--are also found most widely distributed among the meteorites."

"That is an exceedingly significant fact," said Thorwald; "and now do you not see how strongly the meteorites confirm the story of the spectrum, and how everything tells us the universe is one in its physical structure? By these two widely different sources of information you find that beyond doubt other heavenly bodies are made of like materials with the earth. Is it not time now to give your imagination just a moment's play and look upon some of those distant orbs as the probable abode of life?"

"There I cannot follow you," responded the doctor. "I am wanting in imagination; probably born so, as some people are born without an ear for music. Let us stick to facts. Among the recent discoveries in the field of which we have been talking was the finding of some small diamonds in a meteoric ma.s.s. Upon this some enthusiastic writer, whose imaginative soul would be your delight, Thorwald, built this argument: 'Diamonds being pure carbon, their existence necessitates a previous vegetable growth. Hence vegetable life in other worlds is proven, and if vegetable life, it is fair to presume the existence of animal life also. Of course, then, there must be intelligent life, and therefore the stars, or the planets that revolve around the stars, are all filled with men.' This I call not reasoning, but guessing."

"And still," quickly responded Thorwald, "the discovery of diamonds in meteorites was a valuable link in the chain of evidence which you are putting together. Keep on with your investigations. Some time positive knowledge will come to you as it has come to us. But let me appeal once more to your reason. At an earlier stage of development your race no doubt believed the earth was the center of the universe, around which all the heavenly bodies swept in magnificent circles. You have learned that the earth itself, which was formerly thought to be so important an object, is only one of those heavenly bodies flying through s.p.a.ce. You find the earth resembles its nearest companions in being subject to the same laws of motion which govern them, but you have yet to learn that they resemble the earth in the main purpose of their creation. You go into the forest and see thousands of trees. You can find no two alike, and yet all are alike in every material respect. Even the myriads of leaves are all different, and yet all alike. So why may not the millions of stars that fill the sky be like our own sun and like each other, differing in such immaterial things as size and brilliancy, color and const.i.tution, but alike in the chief object of their being, the giving of light and heat, as vivifying forces to dark bodies surrounding them?

And why may not these planets resemble the earth in being, at some stage of their existence, the theater of G.o.d's great designs?

"Let me try to excite your imagination in another way, Doctor. Suppose you should by and by awake and find this visit to Mars only a dream, and then suppose it should be revealed to you in some superhuman way that man was indeed the only race of intelligent beings in the whole universe; that the other planets and all the stars were of no real use; that not one world from that vast region of the milky way and far distant nebulae would ever send forth a note of praise to its Creator, and that the tiny earth was, after all, the center and sum of the universe--tell me, would you not feel lonesome?"

"When you put it in that way, Thorwald," replied the doctor, "I begin to see how unreasonable my position must appear to you. But, however pleasant the idea, I do not see how I can believe that other worlds are inhabited without more evidence than we now possess. This is speaking, of course, without the knowledge we have gained since coming here. But I do not mind saying that your talk has made me wish I could believe it."

I was glad for several reasons that the doctor acknowledged as much as this. First, for Thorwald's sake; for I had been thinking the doctor's obduracy was proving a poor reward for our friend's great kindness to us. I rejoiced, too, that my companion was beginning to show our new acquaintance that, although he had little imagination, he was possessed of a good heart. And, finally, I was myself so much in sympathy with Thorwald's views that I was glad to see his arguments begin to make some impression on the doctor's mind.

But now it seemed to me that Thorwald had much to tell us from his own experience. He had talked so far on this subject from the standpoint of our earthly knowledge, but had hinted more than once that the inhabitants of Mars had more positive evidence than we had ever dreamed could be possible. So I said:

"Your arguments have been very acceptable to me, Thorwald, but can you not strengthen even my faith by speaking now from the results of your own more advanced studies? We must base our belief in the existence of life outside the earth on mere probabilities, which, however strong, lead only to theory and leave us still in doubt. Have you any certain knowledge on the subject, or, I might say, had you any before we came to see you?"

"Oh, yes," replied Thorwald, "we have long had evidence almost as positive as your presence here, fresh from one of our sister planets.

It will give me great pleasure to tell you of some of our marvelous achievements in astronomy. The doctor says he would like to believe in the habitability of other worlds; he must believe in it before I am through if he has any faith in me.

"I would like to say, to begin with, that whatever we have accomplished in this science you on the earth can accomplish. I know enough by comparing your development with our own to feel sure that our present condition foreshadows yours, and that all the knowledge we possess in various directions will come in time to you. Let nothing discourage you in your quest for knowledge. If you seem to have arrived at the limit of possibilities in the telescope, for example, have patience. Difficulties which you think insurmountable, time will remove, and you will be able to penetrate more and more into the mysteries of the universe.

"Our telescopes have gradually increased in power until we have been able to accomplish things that you will no doubt think truly marvelous.

But, before you call any achievement in this science impossible, just look back and compare the ignorance of the early inhabitants of the earth with your present knowledge; and do not be so proud of the wisdom already attained that you cannot also look forward to an enlarged comprehension of things you now call mysteries, and to a much closer acquaintance with the works of G.o.d.

"To our increasing vision the heavens have continued to unfold their wonders. We have penetrated far into the depths of s.p.a.ce only to marvel, at each new revelation, at the power and wisdom of the Creator. The number of stars discovered to our view would be incredible to you, and yet it will be interesting to you to learn that we can still place no bounds to creation. We have, it is true, found the limits of what we call our universe and have mapped out all its boundaries. When this had been done we tried to pierce the surrounding darkness, but for a long time, in spite of our belief that we could not yet see the end, all beyond seemed a void. Recently, however, our faith has been rewarded, for we can now see other universes, buried in far s.p.a.ce but revealed dimly to the higher powers of our telescopes.

"But you are doubtless eager to hear of some more definite knowledge gained from this wide domain. Well, we have determined the distances, size, and motions of many of the stars, resolved star cl.u.s.ters and nebulae, solved the mystery of the double and variable stars, and, what is of more consequence than all these things, we have in many instances discovered the secondary bodies themselves, revolving around a central sun. We now know, what we so long suspected, that the rolling stars are suns like our own, giving light and heat to attending worlds. With this knowledge, can you wonder, Doctor, that we acquired the belief that these worlds, resembling so much the planets of our own system, are fit homes for intelligent beings?"

"I cannot see," replied the doctor, "that such a belief necessarily follows your discovery, which, I must own, was an exceedingly valuable one. I can readily believe that each star that shines in our sky is a sun surrounded by dependent bodies so dark as to be invisible through our terrestrial telescopes, but still I presume even your instruments are not powerful enough to find any inhabitants on those distant worlds?"

"No," replied Thorwald, "but for what other conceivable purpose were these bodies created?"

"I frankly acknowledge that I am not able to answer that question," said the doctor. "If you have many more wonderful discoveries to relate I shall soon have to own myself convinced."

"I am trying to convince your reason," resumed Thorwald, "without the aid of positive evidence, but I may as well proceed now to show you what further knowledge we have gained.

"The nearer planets of our own solar system have been naturally the objects of our close scrutiny. As our telescopes increased in power we diligently studied the surface of these globes, searching for signs of life. We mapped out their features, noted the various phenomena of season and climate, and discovered many ways in which they seemed to be like our world. But for a long time we found no direct evidence that they were inhabited.

"At length, however, one ardent philosopher, full of hope, as we all were, that we had neighbors on some of these globes, brought out the idea that if these neighbors were as far advanced in astronomical science as we were, there ought to be some means of communication between one world and another. The thought took at once, and occasioned the most lively interest. We had no doubt, from what we had learned of these planets, that they were fitted to be, at some time, the home of intelligent beings. Our question was whether the inhabitable period of either of them coincided with that of Mars, and, if so, whether the race was sufficiently developed to be able to see us as well as we could see them.

"The first means suggested to attract the attention of such a race of beings was fire. You can imagine that we could get together material enough to make a pretty big blaze, and we did. We lighted immense fires in various places and kept them burning a long time, but without accomplishing anything. We scanned minutely the surface of each planet, but saw no sign anywhere that our effort at communication was recognized.

"Disappointed, but not discouraged, we determined next to try a system of simple hieroglyphics by throwing up huge mounds on one of our plains.

We thought, if other eyes were studying Mars as closely as we were searching the surface of our sister planets for signs of life, that they would notice any unusual change in our appearance. Then if they did notice it we hoped some means would be found to let us know it.

"It was decided to try first the figure of the circle, because we knew that the form of all heavenly bodies must be the most familiar to intelligent life wherever it existed. It took years of labor to construct the mound, for it was thought best to have it large enough to give the experiment a thorough trial. And now you may believe we considered ourselves well repaid for all our toil and expense when, soon after the circle was completed, our telescopes showed us a similar form actually growing upon the surface of both Saturn and Ura.n.u.s. We immediately replied by beginning the construction of a square, and before this was finished both planets began to answer, one with the triangle and the other with the crescent. The latter was made by Ura.n.u.s, and as soon as it was finished the triangle began to appear beside it, showing to us that Ura.n.u.s was reading from Saturn also.

"Other signs followed, although, of course, the work was very slow, and the experiments are still in progress. Some slight beginning has been made toward the interchange of ideas. The time and labor required will alone prevent extended communication, which would make it possible to form, in the course of ages, a mutual language. As we were the first to start it we propose to try to control the conversation, but if Saturn and Ura.n.u.s choose to steal our idea and gossip between themselves, we know of no way to stop them."

As Thorwald proceeded with this marvelous recital, it was interesting to watch the doctor's face. It was so apparent to me that he was fast losing his skepticism that I was not surprised to hear him say:

"Thorwald, one fact is worth more to me than a world of theory, and if you had begun by relating this wonderful experience you would not have found me so incredulous. Who could refuse to believe with such testimony before him? What news this will be to take back to the earth! But you have, doubtless, other discoveries to relate to us. Excuse me," the doctor continued, turning to me, "for interrupting, even for a moment, our friend's most interesting discourse."

"Let me say," resumed Thorwald, "that your interruption has been helpful to me, for now I know you have lost your doubts and believe with us in this matter."

"These efforts at communication have occupied us for generations, and the close study which we have been obliged to give to the surface of the other planets has made us well acquainted with their characteristics. We have found many likenesses to our own world, as well as various points of difference. The succession of the seasons has been an interesting phenomenon. We have watched with delight the ever-changing rings of our neighbor, Saturn, and can show you pictures of them as they were thousands of years ago."

"We have taken great pleasure in observing the round of seasons on the surface of the earth, not dreaming that we should ever have the privilege of talking face to face with its inhabitants."

"Well, now that we are here, Thorwald," said the doctor, "we want to get all the information possible. So please go on and tell us more of your discoveries. How about those bodies that you have found circling like planets around other suns? Have you any evidence in regard to their inhabitants? Your telescopes cannot surely bring any such bodies near enough to enable you to communicate with them."

"True," replied Thorwald, "but this is another instance where nature has lent us her a.s.sistance. If you have been surprised at some things that I have already said, you will probably find what I am about to relate equally outside of your experience."
