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 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 travelers 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 friends, 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 around 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 four thousand six hundred and fifty miles from the surface of the terrestrial globe."

"More than two thousand 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 twelve thousand yards has been kept up, we shall have made about twenty thousand 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 inter-planetary space.

The lunar disc shone with wonderful purity. Her rays, no longer filtered through the vapory 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 unfavorable to diffusion did not eclipse the neighboring stars.
