Barbicane did not answer. The appearance of this enormous body surprised and troubled him. A collision was possible, and might be attended with deplorable results; either the projectile would deviate from its path, or a shock, breaking its impetus, might precipitate it to the earth; or, lastly, it might be irresistibly drawn away by the powerful asteroid. The president caught at a glance the consequences of these three hypotheses, either of which would, one way or the other, bring their experiment to an unsuccessful and fatal termination. His companions stood silently looking into space. The object grew rapidly as it approached them, and by an optical illusion the projectile seemed to be throwing itself before it.
"By Jove!" exclaimed Michel Ardan, "we shall run into one another!"
Instinctively the travellers drew back. Their dread was great, but it did not last many seconds. The asteroid passed several hundred yards from the projectile and disappeared, not so much from the rapidity of its course, as that its face being opposite the moon, it was suddenly merged into the perfect darkness of space.
"A happy journey to you," exclaimed Michel Ardan, with a sigh of relief. "Surely infinity of space is large enough for a poor little projectile to walk through without fear. Now, what is this portentous globe which nearly struck us?"
"I know," replied Barbicane.
"Oh, indeed! you know everything."
"It is," said Barbicane, "a simple meteorite, but an enormous one, which the attraction of the earth has retained as a satellite."
"Is it possible!" exclaimed Michel Ardan; "the earth then has two moons like Neptune?"
"Yes, my friend, two moons, though it passes generally for having only one; but this second moon is so small, and its speed so great, that the inhabitants of the earth cannot see it. It was by noticing disturbances that a French astronomer, M. Petit, was able to determine the existence of this second satellite and calculate its elements. According to his observations, this meteorite will accomplish its revolution round the earth in three hours and twenty minutes, which implies a wonderful rate of speed."
"Do all astronomers admit the existence of this satellite?" asked Nicholl.
"No," replied Barbicane; "but if, like us, they had met it, they could no longer doubt it. Indeed, I think that this meteorite, which, had it struck the projectile, would have much embarrassed us, will give us the means of deciding what our position in space is."
"How?" said Ardan.
"Because its distance is known, and when we met it, we were exactly 4650 miles from the surface of the terrestrial globe."
"More than 2000 French leagues," exclaimed Michel Ardan. "That beats the express trains of the pitiful globe called the earth."
"I should think so," replied Nicholl, consulting his chronometer; "it is eleven o'clock, and it is only thirteen minutes since we left the American Continent."
"Only thirteen minutes?" said Barbicane.
"Yes," said Nicholl; "and if our initiatory speed of 12,000 yards has been kept up, we shall have made about 20,000 miles in the hour."
"That is all very well, my friends," said the president, "but the insoluble question still remains. Why did we not hear the detonation of the Columbiad?"
For want of an answer the conversation dropped, and Barbicane began thoughtfully to let down the shutter of the second side. He succeeded; and through the uncovered glass the moon filled the projectile with a brilliant light. Nicholl, as an economical man, put out the gas, now useless, and whose brilliancy prevented any observation of the interplanetary space.
The lunar disc shone with wonderful purity. Her rays, no longer filtered through the vapoury atmosphere of the terrestrial globe, shone through the glass, filling the air in the interior of the projectile with silvery reflections. The black curtain of the firmament in reality heightened the moon's brilliancy, which in this void of ether unfavourable to diffusion did not eclipse the neighbouring stars. The heavens, thus seen, presented quite a new aspect, and one which the human eye could never dream of. One may conceive the interest with which these bold men watched the orb of night, the great aim of their journey.
In its motion the earth's satellite was insensibly nearing the zenith, the mathematical point which it ought to attain ninety-six hours later. Her mountains, her plains, every projection was as clearly discernible to their eyes as if they were observing it from some spot upon the earth; but its light was developed through space with wonderful intensity. The disc shone like a platinum mirror. Of the earth flying from under their feet, the travellers had lost all recollection.
It was Captain Nicholl who first recalled their attention to the vanishing globe.
"Yes," said Michel Ardan, "do not let us be ungrateful to it. Since we are leaving our country, let our last looks be directed to it. I wish to see the earth once more before it is quite hidden from my eyes."
To satisfy his companions, Barbicane began to uncover the window at the bottom of the projectile, which would allow them to observe the earth direct. The disc, which the force of the projection had beaten down to the base, was removed, not without difficulty. Its fragments, placed carefully against the wall, might serve again upon occasion. Then a circular gap appeared, nineteen inches in diameter, hollowed out of the lower part of the projectile. A glass cover, six inches thick and strengthened with upper fastenings, closed it tightly. Beneath was fixed an aluminium plate, held in place by bolts. The screws being undone, and the bolts let go, the plate fell down, and visible communication was established between the interior and the exterior.
Michel Ardan knelt by the glass. It was cloudy, seemingly opaque.
"Well!" he exclaimed, "and the earth?"
"The earth?" said Barbicane. "There it is."
"What! that little thread; that silver crescent?"
"Doubtless, Michel. In four days, when the moon will be full, at the very time we shall reach it, the earth will be new, and will only appear to us as a slender crescent which will soon disappear, and for some days will be enveloped in utter darkness."
"That the earth?" repeated Michel Ardan, looking with all his eyes at the thin slip of his native planet.
The explanation given by President Barbicane was correct. The earth, with respect to the projectile, was entering its last phase. It was in its octant, and showed a crescent finely traced on the dark background of the sky. Its light, rendered bluish by the thick strata of the atmosphere was less intense than that of the crescent moon, but it was of considerable dimensions, and looked like an enormous arch stretched across the firmament. Some parts brilliantly lighted, especially on its concave part, showed the presence of high mountains, often disappearing behind thick spots, which are never seen on the lunar disc. They were rings of clouds placed concentrically round the terrestrial globe.
Whilst the travellers were trying to pierce the profound darkness, a brilliant cluster of shooting stars burst upon their eyes. Hundreds of meteorites, ignited by the friction of the atmosphere, irradiated the shadow of the luminous train, and lined the cloudy parts of the disc with their fire. At this period the earth was in its perihelium, and the month of December is so propitious to these shooting stars, that astronomers have counted as many as twenty-four thousand in an hour. But Michel Ardan, disdaining scientific reasonings, preferred thinking that the earth was thus saluting the departure of her three children with her most brilliant fireworks.
Indeed this was all they saw of the globe lost in the shadow, an inferior orb of the solar world, rising and setting to the great planets like a simple morning or evening star! This globe, where they had left all their affections, was nothing more than a fugitive crescent!
Long did the three friends look without speaking, though united in heart, whilst the projectile sped onward with an ever-decreasing speed. Then an irresistible drowsiness crept over their brain. Was it weariness both of body and mind? No doubt; for after the over-excitement of those last hours passed upon earth, reaction was inevitable.
"Well," said Nicholl, "since we must sleep, let us sleep."
And stretching themselves on their couches, they were all three soon in a profound slumber.
But they had not forgotten themselves more than a quarter of an hour, when Barbicane sat up suddenly, and rousing his companions with a loud voice, exclaimed, —
"I have found it!"
"What have you found?" asked Michel Ardan, jumping from his bed.
"The reason why we did not hear the detonation of the Columbiad."
"And it is – ?" said Nicholl.
"Because our projectile travelled faster than the sound!"
CHAPTER III.
THEIR PLACE OF SHELTER
This curious but certainly correct explanation once given, the three friends returned to their slumbers. Could they have found a calmer or more peaceful spot to sleep in? On the earth, houses, towns, cottages, and country feel every shock given to the exterior of the globe. On sea, the vessels rocked by the waves are still in motion; in the air, the balloon oscillates incessantly on the fluid strata of divers densities. This projectile alone, floating in perfect space, in the midst of perfect silence, offered perfect repose.
Thus the sleep of our adventurous travellers might have been indefinitely prolonged, if an unexpected noise had not awakened them at about seven o'clock in the morning of the 2nd of December, eight hours after their departure.
This noise was a very natural barking.
"The dogs! it is the dogs!" exclaimed Michel Ardan, rising at once.
"They are hungry," said Nicholl.
"By Jove!" replied Michel, "we have forgotten them."
