THE CONSEQUENCES OF A DEVIATION
Barbicane had now no fear of the issue of the journey, at least as far as the projectile's impulsive force was concerned; its own speed would carry it beyond the neutral line; it would certainly not return to earth; it would certainly not remain motionless on the line of attraction. One single hypothesis remained to be realized, the arrival of the projectile at its destination by the action of the lunar attraction.
It was in reality a fall of 8,296 leagues on an orb, it is true, where weight could only be reckoned at one sixth of terrestrial weight; a formidable fall, nevertheless, and one against which every precaution must be taken without delay.
These precautions were of two sorts, some to deaden the shock when the projectile should touch the lunar soil, others to delay the fall, and consequently make it less violent.
To deaden the shock, it was a pity that Barbicane was no longer able to employ the means which had so ably weakened the shock at departure, that is to say, by water used as springs and the partition breaks.
The partitions still existed, but water failed, for they could not use their reserve, which was precious, in case during the first days the liquid element should be found wanting on lunar soil.
And indeed this reserve would have been quite insufficient for a spring. The layer of water stored in the projectile at the time of starting upon their journey occupied no less than three feet in depth, and spread over a surface of not less than fifty-four square feet. Besides, the cistern did not contain one-fifth part of it; they must therefore give up this efficient means of deadening the shock of arrival. Happily, Barbicane, not content with employing water, had furnished the movable disc with strong spring plugs, destined to lessen the shock against the base after the breaking of the horizontal partitions.
These plugs still existed; they had only to readjust them and replace the movable disc; every piece, easy to handle, as their weight was now scarcely felt, was quickly mounted.
The different pieces were fitted without trouble, it being only a matter of bolts and screws; tools were not wanting, and soon the reinstated disc lay on steel plugs, like a table on its legs.
One inconvenience resulted from the replacing of the disc, the lower window was blocked up; thus it was impossible for the travelers to observe the moon from that opening while they were being precipitated perpendicularly upon her; but they were obliged to give it up; even by the side openings they could still see vast lunar regions, as an aeronaut sees the earth from his car.
This replacing of the disc was at least an hour's work. It was past twelve when all preparations were finished. Barbicane took fresh observations on the inclination of the projectile, but to his annoyance it had not turned over sufficiently for its fall;it seemed to take a curve parallel to the lunar disc. The orb of night shone splendidly into space, while opposite, the orb of day blazed with fire.
Their situation began to make them uneasy.
"Are we reaching our destination?" said Nicholl.
"Let us act as if we were about reaching it," replied Barbicane.
"You are sceptical," retorted Michel Ardan. "We shall arrive, and that, too, quicker than we like."This answer brought Barbicane back to his preparations, and he occupied himself with placing the contrivances intended to break their descent. We may remember the scene of the meeting held at Tampa Town, in Florida, when Captain Nicholl came forward as Barbicane's enemy and Michel Ardan's adversary. To Captain Nicholl's maintaining that the projectile would smash like glass, Michel replied that he would break their fall by means of rockets properly placed.
Thus, powerful fireworks, taking their starting-point from the base and bursting outside, could, by producing a recoil, check to a certain degree the projectile's speed. These rockets were to burn in space, it is true; but oxygen would not fail them, for they could supply themselves with it, like the lunar volcanoes, the burning of which has never yet been stopped by the want of atmosphere round the moon.
Barbicane had accordingly supplied himself with these fireworks, enclosed in little steel guns, which could be screwed on to the base of the projectile. Inside, these guns were flush with the bottom; outside, they protruded about eighteen inches. There were twenty of them. An opening left in the disc allowed them to light the match with which each was provided. All the effect was felt outside. The burning mixture had already been rammed into each gun. They had, then, nothing to do but raise the metallic buffers fixed in the base, and replace them by the guns, which fitted closely in their places.
This new work was finished about three o'clock, and after taking all these precautions there remained but to wait. But the projectile was perceptibly nearing the moon, and evidently succumbed to her influence to a certain degree; though its own velocity also drew it in an oblique direction. From these conflicting influences resulted a line which might become a tangent. But it was certain that the projectile would not fall directly on the moon; for its lower part, by reason of its weight, ought to be turned toward her.
