This conclusion was a signal for Michel Ardan's hips and hurrahs. And none of the audacious boobies remembered the question that they themselves had solved in the negative. No! the moon is not inhabited; no! the moon is probably not habitable. And yet they were going to try every thing to reach her.
One single question remained to be solved. At what precise moment the projectile would reach the point of equal attraction, on which the travellers must play their last card. In order to calculate this to within a few seconds, Barbicane had only to refer to his notes, and to reckon the different heights taken on the lunar parallels. Thus the time necessary to travel over the distance between the dead point and the south pole would be equal to the distance separating the north pole from the dead point. The hours representing the time travelled over were carefully noted, and the calculation was easy. Barbicane found that this point would be reached at one in the morning on the night of the 7th – 8th of December. So that, if nothing interfered with its course, it would reach the given point in twenty-two hours.
The rockets had primarily been placed to check the fall of the projectile upon the moon, and now they were going to employ them for a directly contrary purpose. In any case they were ready, and they had only to wait for the moment to set fire to them.
"Since there is nothing else to be done," said Nicholl, "I make a proposition."
"What is it?" asked Barbicane.
"I propose to go to sleep."
"What a motion!" exclaimed Michel Ardan.
"It is forty hours since we closed our eyes," said Nicholl. "Some hours of sleep will restore our strength."
"Never," interrupted Michel.
"Well," continued Nicholl, "every one to his taste; I shall go to sleep." And stretching himself on the divan, he soon snored like a forty-eight pounder.
"That Nicholl has a good deal of sense," said Barbicane, "presently I shall follow his example." Some moments after his continued base supported the captain's barytone.
"Certainly," said Michel Ardan, finding himself alone, "these practical people have sometimes most opportune ideas."
And with his long legs stretched out, and his great arms folded under his head, Michel slept in his turn.
But this sleep could be neither peaceful nor lasting, the minds of these three men were too much occupied, and some hours after, about seven in the morning, all three were on foot at the same instant.
The projectile was still leaving the moon, and turning its conical part more and more towards her.
An explicable phenomenon, but one which happily served Barbicane's ends.
Seventeen hours more, and the moment for action would have arrived.
The day seemed long. However bold the travellers might be, they were greatly impressed by the approach of that moment which would decide all – either precipitate their fall on to the moon, or for ever chain them in an immutable orbit. They counted the hours as they passed too slow for their wish; Barbicane and Nicholl were obstinately plunged in their calculations, Michel going and coming between the narrow walls, and watching that impassive moon with a longing eye.
At times recollections of the earth crossed their minds. They saw once more their friends of the Gun Club, and the dearest of all, J. T. Maston. At that moment, the honourable secretary must be filling his post on the Rocky Mountains. If he could see the projectile through the glass of his gigantic telescope, what would he think? After seeing it disappear behind the moon's south pole, he would see them reappear by the north pole! They must therefore be a satellite of a satellite! Had J. T. Maston given this unexpected news to the world? Was this the dénouement of this great enterprise?
But the day passed without incident. The terrestrial midnight arrived. The 8th of December was beginning. One hour more, and the point of equal attraction would be reached. What speed would then animate the projectile? They could not estimate it. But no error could vitiate Barbicane's calculations. At one in the morning this speed ought to be and would be nil.
Besides, another phenomenon would mark the projectile's stopping-point on the neutral line. At that spot the two attractions, lunar and terrestrial, would be annulled. Objects would "weigh" no more. This singular fact, which had surprised Barbicane and his companions so much in going, would be repeated on their return under the very same conditions. At this precise moment they must act.
Already the projectile's conical top was sensibly turned towards the lunar disc, presented in such a way as to utilize the whole of the recoil produced by the pressure of the rocket apparatus. The chances were in favour of the travellers. If its speed was utterly annulled on this dead point, a decided movement towards the moon would suffice, however slight, to determine its fall.
"Five minutes to one," said Nicholl.
"All is ready," replied Michel Ardan, directing a lighted match to the flame of the gas.
"Wait!" said Barbicane, holding his chronometer in his hand.
At that moment weight had no effect. The travellers felt in themselves the entire disappearance of it. They were very near the neutral point, if they did not touch it.
"One o'clock," said Barbicane.
Michel Ardan applied the lighted match to a train in communication with the rockets. No detonation was heard in the inside, for there was no air. But, through the scuttles Barbicane saw a prolonged smoke, the flames of which were immediately extinguished.
The projectile sustained a certain shock, which was sensibly felt in the interior.
The three friends looked and listened without speaking, and scarcely breathing. One might have heard the beating of their hearts amidst this perfect silence.
"Are we falling?" asked Michel Ardan, at length.
"No," said Nicholl, "since the bottom of the projectile is not turning to the lunar disc!"
At this moment, Barbicane, quitting the scuttle, turned to his two companions. He was frightfully pale, his forehead wrinkled, and his lips contracted.
"We are falling!" said he.
"Ah!" cried Michel Ardan, "on to the moon?"
"On to the earth!"
"The devil!" exclaimed Michel Ardan, adding philosophically, "well, when we came into this projectile we were very doubtful as to the ease with which we should get out of it!"
And now this fearful fall had begun. The speed retained had borne the projectile beyond the dead point. The explosion of the rockets could not divert its course. This speed in going had carried it over the neutral line, and in returning had done the same thing. The laws of physics condemned it to pass through every point which it had already gone through. It was a terrible fall, from a height of 160,000 miles, and no springs to break it. According to the laws of gunnery, the projectile must strike the earth with a speed equal to that with which it left the mouth of the Columbiad, a speed of 16,000 yards in the last second.
But to give some figures of comparison, it has been reckoned that an object thrown from the top of the towers of Notre Dame, the height of which is only 200 feet, will arrive on the pavement at a speed of 240 miles per hour. Here the projectile must strike the earth with a speed of 115,200 miles per hour.
"We are lost!" said Michel coolly.
"Very well! if we die," answered Barbicane, with a sort of religious enthusiasm, "the result of our travels will be magnificently spread. It is His own secret that God will tell us! In the other life the soul will want to know nothing, either of machines or engines! It will be identified with eternal wisdom!"
"In fact," interrupted Michel Ardan, "the whole of the other world may well console us for the loss of that inferior orb called the moon!"
Barbicane crossed his arms on his breast, with a motion of sublime resignation, saying at the same time, —
"The will of heaven be done!"
CHAPTER XX.
THE SOUNDINGS OF THE "SUSQUEHANNA."
"Well, lieutenant, and our soundings?"
"I think, sir, that the operation is nearing its completion," replied Lieutenant Bronsfield. "But who would have thought of finding such a depth so near in shore, and only 200 miles from the American coast?"
"Certainly, Bronsfield, there is a great depression," said Captain Blomsberry. "In this spot there is a submarine valley worn by Humboldt's current, which skirts the coast of America as far as the Straits of Magellan."
"These great depths," continued the lieutenant, "are not favourable for laying telegraphic cables. A level bottom, like that supporting the American cable between Valentia and Newfoundland, is much better."
