with much more to the same effect. The professor, by
way of retaliation, had commenced sneering at the "prodigious" mountain
of Montmartre, and the dispute was beginning to look serious when
Servadac entered.

Thinking he could turn the wrangling to some good account, so as to
arrive at the information he was so anxiously seeking, the captain
pretended to espouse the views of his orderly; he consequently brought
upon himself the full force of the professor's wrath.

Rosette's language became more and more violent, till Servadac, feigning
to be provoked beyond endurance, cried:

"You forget, sir, that you are addressing the Governor-General of
Gallia."

"Governor-General! humbug!" roared Rosette. "Gallia is my comet!"

"I deny it," said Servadac. "Gallia has lost its chance of getting back
to the earth. Gallia has nothing to do with you. Gallia is mine; and you
must submit to the government which I please to ordain."

"And who told you that Gallia is not going back to the earth?" asked the
professor, with a look of withering scorn.

"Why, isn't her mass diminished? Isn't she split in half? Isn't her
velocity all altered?" demanded the captain.

"And pray who told you this?" again said the professor, with a sneer.

"Everybody. Everybody knows it, of course," replied Servadac.

"Everybody is very clever. And you always were a very clever scholar
too. We remember that of old, don't we?"

"Sir!"

"You nearly mastered the first elements of science, didn't you?"

"Sir!"

"A credit to your class!"

"Hold your tongue, sir!" bellowed the captain again, as if his anger was
uncontrollable.

"Not I," said the professor.

"Hold your tongue!" repeated Servadac.

"Just because the mass is altered you think the velocity is altered?"

"Hold your tongue!" cried the captain, louder than ever.

"What has mass to do with the orbit? Of how many comets do you know the
mass, and yet you know their movements? Ignorance!" shouted Rosette.

"Insolence!" retorted Servadac.

Ben Zoof, really thinking that his master was angry, made a threatening
movement towards the professor.

"Touch me if you dare!" screamed Rosette, drawing himself up to the
fullest height his diminutive figure would allow. "You shall answer for
your conduct before a court of justice!"

"Where? On Gallia?" asked the captain.

"No; on the earth."

"The earth! Pshaw! You know we shall never get there; our velocity is
changed."

"On the earth," re
