From the Earth to the Moon Part 37

"Those chickens?"

"Yes."

Indeed, half a dozen chickens and a fine c.o.c.k were walking about, flapping their wings and chattering.

"Ah, the awkward things!" exclaimed Michel. "The oxygen has made them revolt."

"But what do you want to do with these chickens?" asked Barbicane.

"To acclimatize them in the moon, by Jove!"

"Then why did you hide them?"

"A joke, my worthy president, a simple joke, which has proved a miserable failure. I wanted to set them free on the lunar continent, without saying anything. Oh, what would have been your amazement on seeing these earthly-winged animals pecking in your lunar fields!"

"You rascal, you unmitigated rascal," replied Barbicane, "you do not want oxygen to mount to the head. You are always what we were under the influence of the gas; you are always foolish!"

"Ah, who says that we were not wise then?" replied Michel Ardan.

After this philosophical reflection, the three friends set about restoring the order of the projectile. Chickens and c.o.c.k were reinstated in their coop. But while proceeding with this operation, Barbicane and his two companions had a most desired perception of a new phenomenon. From the moment of leaving the earth, their own weight, that of the projectile, and the objects it enclosed, had been subject to an increasing diminution. If they could not prove this loss of the projectile, a moment would arrive when it would be sensibly felt upon themselves and the utensils and instruments they used.

It is needless to say that a scale would not show this loss; for the weight destined to weight the object would have lost exactly as much as the object itself; but a spring steelyard for example, the tension of which was independent of the attraction, would have given a just estimate of this loss.

We know that the attraction, otherwise called the weight, is in proportion to the densities of the bodies, and inversely as the squares of the distances. Hence this effect: If the earth had been alone in s.p.a.ce, if the other celestial bodies had been suddenly annihilated, the projectile, according to Newton's laws, would weigh less as it got farther from the earth, but without ever losing its weight entirely, for the terrestrial attraction would always have made itself felt, at whatever distance.

But, in reality, a time must come when the projectile would no longer be subject to the law of weight, after allowing for the other celestial bodies whose effect could not be set down as zero.

Indeed, the projectile's course was being traced between the earth and the moon. As it distanced the earth, the terrestrial attraction diminished: but the lunar attraction rose in proportion. There must come a point where these two attractions would neutralize each other: the projectile would possess weight no longer. If the moon's and the earth's densities had been equal, this point would have been at an equal distance between the two orbs. But taking the different densities into consideration, it was easy to reckon that this point would be situated at 47/60ths of the whole journey, _i.e._, at 78,514 leagues from the earth. At this point, a body having no principle of speed or displacement in itself, would remain immovable forever, being attracted equally by both orbs, and not being drawn more toward one than toward the other.

Now if the projectile's impulsive force had been correctly calculated, it would attain this point without speed, having lost all trace of weight, as well as all the objects within it.

What would happen then? Three hypotheses presented themselves.

1. Either it would retain a certain amount of motion, and pa.s.s the point of equal attraction, and fall upon the moon by virtue of the excess of the lunar attraction over the terrestrial.

2. Or, its speed failing, and unable to reach the point of equal attraction, it would fall upon the moon by virtue of the excess of the lunar attraction over the terrestrial.

3. Or, lastly, animated with sufficient speed to enable it to reach the neutral point, but not sufficient to pa.s.s it, it would remain forever suspended in that spot like the pretended tomb of Mahomet, between the zenith and the nadir.

Such was their situation; and Barbicane clearly explained the consequences to his traveling companions, which greatly interested them. But how should they know when the projectile had reached this neutral point situated at that distance, especially when neither themselves, nor the objects enclosed in the projectile, would be any longer subject to the laws of weight?

Up to this time, the travelers, while admitting that this action was constantly decreasing, had not yet become sensible to its total absence.

But that day, about eleven o'clock in the morning, Nicholl having accidentally let a gla.s.s slip from his hand, the gla.s.s, instead of falling, remained suspended in the air.

"Ah!" exclaimed Michel Ardan, "that is rather an amusing piece of natural philosophy."

And immediately divers other objects, firearms and bottles, abandoned to themselves, held themselves up as by enchantment.

Diana too, placed in s.p.a.ce by Michel, reproduced, but without any trick, the wonderful suspension practiced by Caston and Robert Houdin. Indeed the dog did not seem to know that she was floating in air.

The three adventurous companions were surprised and stupefied, despite their scientific reasonings. They felt themselves being carried into the domain of wonders! they felt that weight was really wanting to their bodies. If they stretched out their arms, they did not attempt to fall. Their heads shook on their shoulders. Their feet no longer clung to the floor of the projectile. They were like drunken men having no stability in themselves.

Fancy has depicted men without reflection, others without shadow.

But here reality, by the neutralizations of attractive forces, produced men in whom nothing had any weight, and who weighed nothing themselves.

Suddenly Michel, taking a spring, left the floor and remained suspended in the air, like Murillo's monk of the _Cusine des Anges_.

The two friends joined him instantly, and all three formed a miraculous "Ascension" in the center of the projectile.

"Is it to be believed? is it probable? is it possible?"

exclaimed Michel; "and yet it is so. Ah! if Raphael had seen us thus, what an `a.s.sumption' he would have thrown upon canvas!"

"The `a.s.sumption' cannot last," replied Barbicane. "If the projectile pa.s.ses the neutral point, the lunar attraction will draw us to the moon."

"Then our feet will be upon the roof," replied Michel.

"No," said Barbicane, "because the projectile's center of gravity is very low; it will only turn by degrees."

"Then all our portables will be upset from top to bottom, that is a fact."

"Calm yourself, Michel," replied Nicholl; "no upset is to be feared; not a thing will move, for the projectile's evolution will be imperceptible."

"Just so," continued Barbicane; "and when it has pa.s.sed the point of equal attraction, its base, being the heavier, will draw it perpendicularly to the moon; but, in order that this phenomenon should take place, we must have pa.s.sed the neutral line."

"Pa.s.s the neutral line," cried Michel; "then let us do as the sailors do when they cross the equator."

A slight side movement brought Michel back toward the padded side; thence he took a bottle and gla.s.ses, placed them "in s.p.a.ce" before his companions, and, drinking merrily, they saluted the line with a triple hurrah. The influence of these attractions scarcely lasted an hour; the travelers felt themselves insensibly drawn toward the floor, and Barbicane fancied that the conical end of the projectile was varying a little from its normal direction toward the moon. By an inverse motion the base was approaching first; the lunar attraction was prevailing over the terrestrial; the fall toward the moon was beginning, almost imperceptibly as yet, but by degrees the attractive force would become stronger, the fall would be more decided, the projectile, drawn by its base, would turn its cone to the earth, and fall with ever-increasing speed on to the surface of the Selenite continent; their destination would then be attained. Now nothing could prevent the success of their enterprise, and Nicholl and Michel Ardan shared Barbicane's joy.

Then they chatted of all the phenomena which had astonished them one after the other, particularly the neutralization of the laws of weight. Michel Ardan, always enthusiastic, drew conclusions which were purely fanciful.

"Ah, my worthy friends," he exclaimed, "what progress we should make if on earth we could throw off some of that weight, some of that chain which binds us to her; it would be the prisoner set at liberty; no more fatigue of either arms or legs. Or, if it is true that in order to fly on the earth's surface, to keep oneself suspended in the air merely by the play of the muscles, there requires a strength a hundred and fifty times greater than that which we possess, a simple act of volition, a caprice, would bear us into s.p.a.ce, if attraction did not exist."

"Just so," said Nicholl, smiling; "if we could succeed in suppressing weight as they suppress pain by anaesthesia, that would change the face of modern society!"

"Yes," cried Michel, full of his subject, "destroy weight, and no more burdens!"

"Well said," replied Barbicane; "but if nothing had any weight, nothing would keep in its place, not even your hat on your head, worthy Michel; nor your house, whose stones only adhere by weight; nor a boat, whose stability on the waves is only caused by weight; not even the ocean, whose waves would no longer be equalized by terrestrial attraction; and lastly, not even the atmosphere, whose atoms, being no longer held in their places, would disperse in s.p.a.ce!"

"That is tiresome," retorted Michel; "nothing like these matter-of-fact people for bringing one back to the bare reality."

"But console yourself, Michel," continued Barbicane, "for if no orb exists from whence all laws of weight are banished, you are at least going to visit one where it is much less than on the earth."

"The moon?"

"Yes, the moon, on whose surface objects weigh six times less than on the earth, a phenomenon easy to prove."

"And we shall feel it?" asked Michel.

"Evidently, as two hundred pounds will only weigh thirty pounds on the surface of the moon."
