Whether Michel Ardan’s antagonist hazarded any further arguments or not it is impossible to say, for the uproarious shouts of the crowd would not allow any expression of opinion to gain a hearing. On silence being restored, the triumphant orator contented himself with adding the following remarks:
“Gentlemen, you will observe that I have but slightly touched upon this great question. There is another altogether different line of argument in favor of the habitability of the stars, which I omit for the present. I only desire to call attention to one point. To those who maintain that the planets are not inhabited one may reply: You might be perfectly in the right, if you could only show that the earth is the best possible world, in spite of what Voltaire has said. She has but one satellite, while Jupiter, Uranus, Saturn, Neptune have each several, an advantage by no means to be despised. But that which renders our own globe so uncomfortable is the inclination of its axis to the plane of its orbit. Hence the inequality of days and nights; hence the disagreeable diversity of the seasons. On the surface of our unhappy spheroid we are always either too hot or too cold; we are frozen in winter, broiled in summer; it is the planet of rheumatism, coughs, bronchitis; while on the surface of Jupiter, for example, where the axis is but slightly inclined, the inhabitants may enjoy uniform temperatures. It possesses zones of perpetual springs, summers, autumns, and winters; every Jovian may choose for himself what climate he likes, and there spend the whole of his life in security from all variations of temperature. You will, I am sure, readily admit this superiority of Jupiter over our own planet, to say nothing of his years, which each equal twelve of ours! Under such auspices and such marvelous conditions of existence, it appears to me that the inhabitants of so fortunate a world must be in every respect superior to ourselves. All we require, in order to attain such perfection, is the mere trifle of having an axis of rotation less inclined to the plane of its orbit!”
“Hurrah!” roared an energetic voice, “let us unite our efforts, invent the necessary machines, and rectify the earth’s axis!”
A thunder of applause followed this proposal, the author of which was, of course, no other than J. T. Maston. And, in all probability, if the truth must be told, if the Yankees could only have found a point of application for it, they would have constructed a lever capable of raising the earth and rectifying its axis. It was just this deficiency which baffled these daring mechanicians.
ATTACK AND RIPOSTE
As soon as the excitement had subsided, the following words were heard uttered in a strong and determined voice:
“Now that the speaker has favored us with so much imagination, would he be so good as to return to his subject, and give us a little practical view of the question?”
All eyes were directed toward the person who spoke. He was a little dried-up man, of an active figure, with an American “goatee” beard. Profiting by the different movements in the crowd, he had managed by degrees to gain the front row of spectators. There, with arms crossed and stern gaze, he watched the hero of the meeting. After having put his question he remained silent, and appeared to take no notice of the thousands of looks directed toward himself, nor of the murmur of disapprobation excited by his words. Meeting at first with no reply, he repeated his question with marked emphasis, adding, “We are here to talk about the moon and not about the earth.”
“You are right, sir,” replied Michel Ardan; “the discussion has become irregular. We will return to the moon.”
“Sir,” said the unknown, “you pretend that our satellite is inhabited. Very good, but if Selenites do exist, that race of beings assuredly must live without breathing, for— I warn you for your own sake— there is not the smallest particle of air on the surface of the moon.”
At this remark Ardan pushed up his shock of red hair; he saw that he was on the point of being involved in a struggle with this person upon the very gist of the whole question. He looked sternly at him in his turn and said:
“Oh! so there is no air in the moon? And pray, if you are so good, who ventures to affirm that?
“The men of science.”
“Really?”
“Really.”
“Sir,” replied Michel, “pleasantry apart, I have a profound respect for men of science who do possess science, but a profound contempt for men of science who do not.”
“Do you know any who belong to the latter category?”
“Decidedly. In France there are some who maintain that, mathematically, a bird cannot possibly fly; and others who demonstrate theoretically that fishes were never made to live in water.”
“I have nothing to do with persons of that description, and I can quote, in support of my statement, names which you cannot refuse deference to.”
“Then, sir, you will sadly embarrass a poor ignorant, who, besides, asks nothing better than to learn.”
“Why, then, do you introduce scientific questions if you have never studied them?” asked the unknown somewhat coarsely.
“For the reason that `he is always brave who never suspects danger.’ I know nothing, it is true; but it is precisely my very weakness which constitutes my strength.”
“Your weakness amounts to folly,” retorted the unknown in a passion.
“All the better,” replied our Frenchman, “if it carries me up to the moon.”
Barbicane and his colleagues devoured with their eyes the intruder who had so boldly placed himself in antagonism to their enterprise. Nobody knew him, and the president, uneasy as to the result of so free a discussion, watched his new friend with some anxiety. The meeting began to be somewhat fidgety also, for the contest directed their attention to the dangers, if not the actual impossibilities, of the proposed expedition.
“Sir,” replied Ardan’s antagonist, “there are many and incontrovertible reasons which prove the absence of an atmosphere in the moon. I might say that, a priori, if one ever did exist, it must have been absorbed by the earth; but I prefer to bring forward indisputable facts.”
“Bring them forward then, sir, as many as you please.”
“You know,” said the stranger, “that when any luminous rays cross a medium such as the air, they are deflected out of the straight line; in other words, they undergo refraction. Well! When stars are occulted by the moon, their rays, on grazing the edge of her disc, exhibit not the least deviation, nor offer the slightest indication of refraction. It follows, therefore, that the moon cannot be surrounded by an atmosphere.
“In point of fact,” replied Ardan, “this is your chief, if not your only argument; and a really scientific man might be puzzled to answer it. For myself, I will simply say that it is defective, because it assumes that the angular diameter of the moon has been completely determined, which is not the case. But let us proceed. Tell me, my dear sir, do you admit the existence of volcanoes on the moon’s surface?”
“Extinct, yes! In activity, no!”
“These volcanoes, however, were at one time in a state of activity?”
“True, but, as they furnish themselves the oxygen necessary for combustion, the mere fact of their eruption does not prove the presence of an atmosphere.”
“Proceed again, then; and let us set aside this class of arguments in order to come to direct observations. In 1715 the astronomers Louville and Halley, watching the eclipse of the 3rd of May, remarked some very extraordinary scintillations. These jets of light, rapid in nature, and of frequent recurrence, they attributed to thunderstorms generated in the lunar atmosphere.”
“In 1715,” replied the unknown, “the astronomers Louville and Halley mistook for lunar phenomena some which were purely terrestrial, such as meteoric or other bodies which are generated in our own atmosphere. This was the scientific explanation at the time of the facts; and that is my answer now.”
“On again, then,” replied Ardan; “Herschel, in 1787, observed a great number of luminous points on the moon’s surface, did he not?”
“Yes! but without offering any solution of them. Herschel himself never inferred from them the necessity of a lunar atmosphere. And I may add that Baeer and Maedler, the two great authorities upon the moon, are quite agreed as to the entire absence of air on its surface.”
A movement was here manifest among the assemblage, who appeared to be growing excited by the arguments of this singular personage.
“Let us proceed,” replied Ardan, with perfect coolness, “and come to one important fact. A skillful French astronomer, M. Laussedat, in watching the eclipse of July 18, 1860, probed that the horns of the lunar crescent were rounded and truncated. Now, this appearance could only have been produced by a deviation of the solar rays in traversing the atmosphere of the moon. There is no other possible explanation of the facts.”
“But is this established as a fact?”
“Absolutely certain!”
A counter-movement here took place in favor of the hero of the meeting, whose opponent was now reduced to silence. Ardan resumed the conversation; and without exhibiting any exultation at the advantage he had gained, simply said:
“You see, then, my dear sir, we must not pronounce with absolute positiveness against the existence of an atmosphere in the moon. That atmosphere is, probably, of extreme rarity; nevertheless at the present day science generally admits that it exists.”
“Not in the mountains, at all events,” returned the unknown, unwilling to give in.
“No! but at the bottom of the valleys, and not exceeding a few hundred feet in height.”
“In any case you will do well to take every precaution, for the air will be terribly rarified.”
“My good sir, there will always be enough for a solitary individual; besides, once arrived up there, I shall do my best to economize, and not to breathe except on grand occasions!”
A tremendous roar of laughter rang in the ears of the mysterious interlocutor, who glared fiercely round upon the assembly.
“Then,” continued Ardan, with a careless air, “since we are in accord regarding the presence of a certain atmosphere, we are forced to admit the presence of a certain quantity of water. This is a happy consequence for me. Moreover, my amiable contradictor, permit me to submit to you one further observation. We only know one side of the moon’s disc; and if there is but little air on the face presented to us, it is possible that there is plenty on the one turned away from us.”
“And for what reason?”
“Because the moon, under the action of the earth’s attraction, has assumed the form of an egg, which we look at from the smaller end. Hence it follows, by Hausen’s calculations, that its center of gravity is situated in the other hemisphere. Hence it results that the great mass of air and water must have been drawn away to the other face of our satellite during the first days of its creation.”
“Pure fancies!” cried the unknown.
“No! Pure theories! which are based upon the laws of mechanics, and it seems difficult to me to refute them. I appeal then to this meeting, and I put it to them whether life, such as exists upon the earth, is possible on the surface of the moon?”
Three hundred thousand auditors at once applauded the proposition. Ardan’s opponent tried to get in another word, but he could not obtain a hearing. Cries and menaces
