“Yes,” replied Michel, with an amiable swagger, “I have a few ideas of that sort.”

“But that idea does not spring from Michel,” answered Nicholl.

“Well, then, I am a plagiarist.”

“No doubt about it. According to the ancients, the Arcadians pretend that their ancestors inhabited the earth before the moon became her satellite. Starting from this fact, some scientific men have seen in the moon a comet whose orbit will one day bring it so near to the earth that it will be held there by its attraction.”

“Is there any truth in this hypothesis?” asked Michel.

“None whatever,” said Barbicane, “and the proof is, that the moon has preserved no trace of the gaseous envelope which always accompanies comets.”

“But,” continued Nicholl, “Before becoming the earth’s satellite, could not the moon, when in her perihelion, pass so near the sun as by evaporation to get rid of all those gaseous substances?”

“It is possible, friend Nicholl, but not probable.”

“Why not?”

“Because—Faith I do not know.”
