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 fell upon him like hail.
"Enough! enough!" cried some.
"Drive the intruder off!" shouted others.
"Turn him out!" roared the exasperated crowd.
But he, holding firmly on to the platform, did not budge an inch, and let the storm pass on, which would soon have assumed formidable proportions, if Michel Ardan had not quieted it by a gesture. He was too chivalrous to abandon his opponent in an apparent extremity.
"You wished to say a few more words?" he asked, in a pleasant voice.
"Yes, a thousand; or rather, no, only one! If you persevere in your enterprise, you must be a----""Very rash person! How can you treat me as such? me, who have demanded a cylindro-conical projectile, in order to prevent turning round and round on my way like a squirrel?""But, unhappy man, the dreadful recoil will smash you to pieces at your starting.""My dear contradictor, you have just put your finger upon the true and only difficulty; nevertheless, I have too good an opinion of the industrial genius of the Americans not to believe that they will succeed in overcoming it.""But the heat developed by the rapidity of the projectile in crossing the strata of air?""Oh! the walls are thick, and I shall soon have crossed the atmosphere.""But victuals and water?"
"I have calculated for a twelvemonth's supply, and I shall be only four days on the journey.""But for air to breathe on the road?"
"I shall make it by a chemical process."
