"On the contrary," continued Barbicane.
"One moment," said Michel, interrupting his grave companion.
"What do you want?"
"I ask to be allowed to continue the explanation.""And why?"
"To prove that I understand."
"Get along with you," said Barbicane, smiling.
"On the contrary," said Michel, imitating the tone and gestures of the president, "on the contrary, when the visible face of the moon is lit by the sun, it is because the moon is full, that is to say, opposite the sun with regard to the earth. The distance separating it from the radiant orb is then increased in round numbers to 400,000 miles, and the heat which she receives must be a little less.""Very well said!" exclaimed Barbicane. "Do you know, Michel, that, for an amateur, you are intelligent.""Yes," replied Michel coolly, "we are all so on the Boulevard des Italiens."Barbicane gravely grasped the hand of his amiable companion, and continued to enumerate the advantages reserved for the inhabitants of the visible face.
Among others, he mentioned eclipses of the sun, which only take place on this side of the lunar disc; since, in order that they may take place, it is necessary for the moon to be _in opposition_. These eclipses, caused by the interposition of the earth between the moon and the sun, can last _two hours_; during which time, by reason of the rays refracted by its atmosphere, the terrestrial globe can appear as nothing but a black point upon the sun.
"So," said Nicholl, "there is a hemisphere, that invisible hemisphere which is very ill supplied, very ill treated, by nature.""Never mind," replied Michel; "if we ever become Selenites, we will inhabit the visible face. I like the light.""Unless, by any chance," answered Nicholl, "the atmosphere should be condensed on the other side, as certain astronomers pretend.""That would be a consideration," said Michel.
Breakfast over, the observers returned to their post. They tried to see through the darkened scuttles by extinguishing all light in the projectile; but not a luminous spark made its way through the darkness.
One inexplicable fact preoccupied Barbicane. Why, having passed within such a short distance of the moon--about twenty-five miles only-- why the projectile had not fallen? If its speed had been enormous, he could have understood that the fall would not have taken place; but, with a relatively moderate speed, that resistance to the moon's attraction could not be explained.
Was the projectile under some foreign influence? Did some kind of body retain it in the ether? It was quite evident that it could never reach any point of the moon. Whither was it going?
Was it going farther from, or nearing, the disc? Was it being borne in that profound darkness through the infinity of space?
How could they learn, how calculate, in the midst of this night?
All these questions made Barbicane uneasy, but he could not solve them.
Certainly, the invisible orb was _there_, perhaps only some few miles off; but neither he nor his companions could see it.
If there was any noise on its surface, they could not hear it.
Air, that medium of sound, was wanting to transmit the groanings of that moon which the Arabic legends call "a man already half granite, and still breathing."One must allow that that was enough to aggravate the most patient observers. It was just that unknown hemisphere which was stealing from their sight. That face which fifteen days sooner, or fifteen days later, had been, or would be, splendidly illuminated by the solar rays, was then being lost in utter darkness.
In fifteen days where would the projectile be? Who could say?
Where would the chances of conflicting attractions have drawn it to? The disappointment of the travelers in the midst of this utter darkness may be imagined. All observation of the lunar disc was impossible. The constellations alone claimed all their attention; and we must allow that the astronomers Faye, Charconac, and Secchi, never found themselves in circumstances so favorable for their observation.
Indeed, nothing could equal the splendor of this starry world, bathed in limpid ether. Its diamonds set in the heavenly vault sparkled magnificently. The eye took in the firmament from the Southern Cross to the North Star, those two constellations which in 12,000 years, by reason of the succession of equinoxes, will resign their part of the polar stars, the one to Canopus in the southern hemisphere, the other to Wega in the northern.
