"Is it possible!" exclaimed Michel Ardan in a serious tone, as if they had told him of some serious event. "What I particularly like in your definition of the hyperbola (I was going to say hyperblague) is that it is still more obscure than the word you pretend to define."
Nicholl and Barbicane cared little for Michel Ardan"s fun.
They were deep in a scientific discussion. What curve would the projectile follow? was their hobby. One maintained the hyperbola, the other the parabola. They gave each other reasons bristling with _x_. Their arguments were couched in language which made Michel jump. The discussion was hot, and neither would give up his chosen curve to his adversary.
This scientific dispute lasted so long that it made Michel very impatient.
"Now, gentlemen cosines, will you cease to throw parabolas and hyperbolas at each other"s heads? I want to understand the only interesting question in the whole affair. We shall follow one or the other of these curves? Good. But where will they lead us to?"
"Nowhere," replied Nicholl.
"How, nowhere?"
"Evidently," said Barbicane, "they are open curves, which may be prolonged indefinitely."
"Ah, savants!" cried Michel; "and what are either the one or the other to us from the moment we know that they equally lead us into infinite s.p.a.ce?"
Barbicane and Nicholl could not forbear smiling. They had just been creating "art for art"s sake." Never had so idle a question been raised at such an inopportune moment. The sinister truth remained that, whether hyperbolically or parabolically borne away, the projectile would never again meet either the earth or the moon.
What would become of these bold travelers in the immediate future?
If they did not die of hunger, if they did not die of thirst, in some days, when the gas failed, they would die from want of air, unless the cold had killed them first. Still, important as it was to economize the gas, the excessive lowness of the surrounding temperature obliged them to consume a certain quant.i.ty.
Strictly speaking, they could do without its _light_, but not without its _heat_. Fortunately the caloric generated by Reiset"s and Regnaut"s apparatus raised the temperature of the interior of the projectile a little, and without much expenditure they were able to keep it bearable.
But observations had now become very difficult. the dampness of the projectile was condensed on the windows and congealed immediately.
This cloudiness had to be dispersed continually. In any case they might hope to be able to discover some phenomena of the highest interest.
But up to this time the disc remained dumb and dark. It did not answer the multiplicity of questions put by these ardent minds; a matter which drew this reflection from Michel, apparently a just one:
"If ever we begin this journey over again, we shall do well to choose the time when the moon is at the full."
"Certainly," said Nicholl, "that circ.u.mstance will be more favorable.
I allow that the moon, immersed in the sun"s rays, will not be visible during the transit, but instead we should see the earth, which would be full. And what is more, if we were drawn round the moon, as at this moment, we should at least have the advantage of seeing the invisible part of her disc magnificently lit."
"Well said, Nicholl," replied Michel Ardan. "What do you think, Barbicane?"
"I think this," answered the grave president: "If ever we begin this journey again, we shall start at the same time and under the same conditions. Suppose we had attained our end, would it not have been better to have found continents in broad daylight than a country plunged in utter darkness? Would not our first installation have been made under better circ.u.mstances?
Yes, evidently. As to the invisible side, we could have visited it in our exploring expeditions on the lunar globe. So that the time of the full moon was well chosen. But we ought to have arrived at the end; and in order to have so arrived, we ought to have suffered no deviation on the road."
"I have nothing to say to that," answered Michel Ardan.
"Here is, however, a good opportunity lost of observing the other side of the moon."
But the projectile was now describing in the shadow that incalculable course which no sight-mark would allow them to ascertain. Had its direction been altered, either by the influence of the lunar attraction, or by the action of some unknown star? Barbicane could not say. But a change had taken place in the relative position of the vehicle; and Barbicane verified it about four in the morning.
The change consisted in this, that the base of the projectile had turned toward the moon"s surface, and was so held by a perpendicular pa.s.sing through its axis. The attraction, that is to say the weight, had brought about this alteration. The heaviest part of the projectile inclined toward the invisible disc as if it would fall upon it.
Was it falling? Were the travelers attaining that much desired end?
No. And the observation of a sign-point, quite inexplicable in itself, showed Barbicane that his projectile was not nearing the moon, and that it had shifted by following an almost concentric curve.
This point of mark was a luminous brightness, which Nicholl sighted suddenly, on the limit of the horizon formed by the black disc. This point could not be confounded with a star.
It was a reddish incandescence which increased by degrees, a decided proof that the projectile was shifting toward it and not falling normally on the surface of the moon.
"A volcano! it is a volcano in action!" cried Nicholl; "a disemboweling of the interior fires of the moon! That world is not quite extinguished."
"Yes, an eruption," replied Barbicane, who was carefully studying the phenomenon through his night gla.s.s. "What should it be, if not a volcano?"
"But, then," said Michel Ardan, "in order to maintain that combustion, there must be air. So the atmosphere does surround that part of the moon."
"Perhaps so," replied Barbicane, "but not necessarily.
The volcano, by the decomposition of certain substances, can provide its own oxygen, and thus throw flames into s.p.a.ce. It seems to me that the deflagration, by the intense brilliancy of the substances in combustion, is produced in pure oxygen. We must not be in a hurry to proclaim the existence of a lunar atmosphere."
The fiery mountain must have been situated about the [email protected] south lat.i.tude on the invisible part of the disc; but, to Barbicane"s great displeasure, the curve which the projectile was describing was taking it far from the point indicated by the eruption.
Thus he could not determine its nature exactly. Half an hour after being sighted, this luminous point had disappeared behind the dark horizon; but the verification of this phenomenon was of considerable consequence in their selenographic studies.
It proved that all heat had not yet disappeared from the bowels of this globe; and where heat exists, who can affirm that the vegetable kingdom, nay, even the animal kingdom itself, has not up to this time resisted all destructive influences? The existence of this volcano in eruption, unmistakably seen by these earthly savants, would doubtless give rise to many theories favorable to the grave question of the habitability of the moon.
Barbicane allowed himself to be carried away by these reflections.
He forgot himself in a deep reverie in which the mysterious destiny of the lunar world was uppermost. He was seeking to combine together the facts observed up to that time, when a new incident recalled him briskly to reality. This incident was more than a cosmical phenomenon; it was a threatened danger, the consequence of which might be disastrous in the extreme.
Suddenly, in the midst of the ether, in the profound darkness, an enormous ma.s.s appeared. It was like a moon, but an incandescent moon whose brilliancy was all the more intolerable as it cut sharply on the frightful darkness of s.p.a.ce. This ma.s.s, of a circular form, threw a light which filled the projectile.
The forms of Barbicane, Nicholl, and Michel Ardan, bathed in its white sheets, a.s.sumed that livid spectral appearance which physicians produce with the fict.i.tious light of alcohol impregnated with salt.
"By Jove!" cried Michel Ardan, "we are hideous. What is that ill-conditioned moon?"
"A meteor," replied Barbicane.
"A meteor burning in s.p.a.ce?"
"Yes."
This shooting globe suddenly appearing in shadow at a distance of at most 200 miles, ought, according to Barbicane, to have a diameter of 2,000 yards. It advanced at a speed of about one mile and a half per second. It cut the projectile"s path and must reach it in some minutes. As it approached it grew to enormous proportions.
Imagine, if possible, the situation of the travelers! It is impossible to describe it. In spite of their courage, their _sang-froid_, their carelessness of danger, they were mute, motionless with stiffened limbs, a prey to frightful terror.
Their projectile, the course of which they could not alter, was rushing straight on this ignited ma.s.s, more intense than the open mouth of an oven. It seemed as though they were being precipitated toward an abyss of fire.
Barbicane had seized the hands of his two companions, and all three looked through their half-open eyelids upon that asteroid heated to a white heat. If thought was not destroyed within them, if their brains still worked amid all this awe, they must have given themselves up for lost.
Two minutes after the sudden appearance of the meteor (to them two centuries of anguish) the projectile seemed almost about to strike it, when the globe of fire burst like a bomb, but without making any noise in that void where sound, which is but the agitation of the layers of air, could not be generated.
Nicholl uttered a cry, and he and his companions rushed to the scuttle. What a sight! What pen can describe it?
What palette is rich enough in colors to reproduce so magnificent a spectacle?
It was like the opening of a crater, like the scattering of an immense conflagration. Thousands of luminous fragments lit up and irradiated s.p.a.ce with their fires. Every size, every color, was there intermingled. There were rays of yellow and pale yellow, red, green, gray-- a crown of fireworks of all colors.
Of the enormous and much-dreaded globe there remained nothing but these fragments carried in all directions, now become asteroids in their turn, some flaming like a sword, some surrounded by a whitish cloud, and others leaving behind them trains of brilliant cosmical dust.
These incandescent blocks crossed and struck each other, scattering still smaller fragments, some of which struck the projectile. Its left scuttle was even cracked by a violent shock. It seemed to be floating amid a hail of howitzer sh.e.l.ls, the smallest of which might destroy it instantly.
The light which saturated the ether was so wonderfully intense, that Michel, drawing Barbicane and Nicholl to his window, exclaimed, "The invisible moon, visible at last!"
And through a luminous emanation, which lasted some seconds, the whole three caught a glimpse of that mysterious disc which the eye of man now saw for the first time. What could they distinguish at a distance which they could not estimate? Some lengthened bands along the disc, real clouds formed in the midst of a very confined atmosphere, from which emerged not only all the mountains, but also projections of less importance; its circles, its yawning craters, as capriciously placed as on the visible surface.
