“Ay, more than that,” said the lieutenant; “our Gallia is certain to be far more than a mere object of scientific interest or curiosity. Why should we doubt that the elements of a comet which has once come into collision with the earth have by this time been accurately calculated? What our friend the professor has done here, has been done likewise on the earth, where, beyond a question, all manner of expedients are being discussed as to the best way of mitigating the violence of a concussion that must occur.” The lieutenant’s conjectures were so reasonable that they commanded assent. Gallia could scarcely be otherwise than an object of terror to the inhabitants of the earth, who could by no means be certain that a second collision would be comparatively so harmless as the first. Even to the Gallians themselves, much as they looked forward to the event, the prospect was not unmixed with alarm, and they would rejoice in the invention of any device by which it was likely the impetus of the shock might be deadened. Christmas arrived, and was marked by appropriate religious observance by everyone in the community, with the exception of the Jew, who made a point of secluding himself more obstinately than ever in the gloomy recesses of his retreat. To Ben Zoof the last week of the year was full of bustle. The arrangements for the New Year _fete_ were entrusted to him, and he was anxious, in spite of the resources of Gallia being so limited, to make the program for the great day as attractive as possible. It was a matter of debate that night whether the professor should be invited to join the party; it was scarcely likely that he would care to come, but, on the whole, it was felt to be advisable to ask him. At first Captain Servadac thought of going in person with the invitation; but, remembering Rosette’s dislike to visitors, he altered his mind, and sent young Pablo up to the observatory with a formal note, requesting the pleasure of Professor Rosette’s company at the New Year’s _fete_. Pablo was soon back, bringing no answer except that the professor had told him that “to-day was the 125th of June, and that to-morrow would be the 1st of July.” Consequently, Servadac and the count took it for granted that Palmyrin Rosette declined their invitation.
