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 been already rammed into each gun. They had, then, nothing to do but to 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 towards her. Barbicane's uneasiness increased as he saw his projectile resist the influence of gravitation. The Unknown was opening before him, the Unknown in interplanetary space. The man of science thought he had foreseen the only three hypotheses possible—the return to the earth, the return to the moon, or stagnation on the neutral line; and here a fourth hypothesis, big with all the terrors of the Infinite, surged up inopportunely. To face it without flinching, one must be a resolute savant like Barbicane, a phlegmatic being like Nicholl, or an audacious adventurer like Michel Ardan. Conversation was started upon this subject. Other men would have considered the question from a practical point of view; they would have asked themselves whither their projectile carriage was carrying them. Not so with these; they sought for the cause which produced this effect. "So we have become diverted from our route," said Michel; "but why?"
