It ended with the following double hypothesis:—­Either the attraction of the moon would end by carrying the day, and the travellers would reach their goal; or the projectile, fixed in an immutable orbit, would gravitate around the lunar disc to the end of time.

In either of these alternatives what would be the travellers’ fate?  It is true they had provisions enough for some time.  But even supposing that their bold enterprise were crowned with success, how would they return?  Could they ever return?  Would news of them ever reach the earth?  These questions, debated upon by the most learned writers of the time, intensely interested the public.

A remark may here be made which ought to be meditated upon by too impatient observers.  When a savant announces a purely speculative discovery to the public he cannot act with too much prudence.  No one is obliged to discover either a comet or a satellite, and those who make a mistake in such a case expose themselves justly to public ridicule.  Therefore it is better to wait; and that is what impatient J.T.  Maston ought to have done before sending to the world the telegram which, according to him, contained the last communication about this enterprise.

In fact, the telegram contained errors of two sorts, verified later:—­1.  Errors of observation concerning the distance of the projectile from the surface of the moon, for upon the date of the 11th of December it was impossible to perceive it, and that which J.T.  Maston had seen, or thought he saw, could not be the bullet from the Columbiad. 2.  A theoretic error as to the fate of the said projectile, for making it a satellite of the moon was an absolute contradiction of the laws of rational mechanics.

One hypothesis only made by the astronomers of Long’s Peak might be realised, the one that foresaw the case when the travellers—­if any yet existed—­should unite their efforts with the lunar attraction so as to reach the surface of the disc.

Now these men, as intelligent as they were bold, had survived the terrible shock at departure, and their journey in their bullet-carriage will be related in its most dramatic as well as in its most singular details.  This account will put an end to many illusions and previsions, but it will give a just idea of the various circumstances incidental to such an enterprise, and will set in relief Barbicane’s scientific instincts, Nicholl’s industrial resources, and the humorous audacity of Michel Ardan.

Besides, it will prove that their worthy friend J.T.  Maston was losing his time when, bending over the gigantic telescope, he watched the course of the moon across the planetary regions.

CHAPTER I.

FROM 10.20 P.M.  TO 10.47 P.M.

When ten o’clock struck, Michel Ardan, Barbicane, and Nicholl said good-bye to the numerous friends they left upon the earth.  The two dogs, destined to acclimatise the canine race upon the lunar continents, were already imprisoned in the projectile.  The three travellers approached the orifice of the enormous iron tube, and a crane lowered them to the conical covering of the bullet.
