Besides, he never let them get out of sight. His home was henceforth the post at Long's Peak; his horizon, the mirror of that immense reflector. As soon as the moon rose above the horizon, he immediately caught her in the field of the telescope; he never let her go for an instant out of his sight, and followed her assiduously in her course through the stellar spaces. He watched with untiring patience the passage of the projectile across her silvery disc, and really the worthy man remained in perpetual communication with his three friends, whom he did not despair of seeing again some day. "Those three men," said he, "have carried into space all the resources of art, science, and industry. With that, one can do anything; and you will see that, some day, they will come out all right." ROUND THE MOON: A Sequel To FROM THE EARTH TO THE MOON. —————— PRELIMINARY CHAPTER. RECAPITULATING THE FIRST PART OF THIS WORK, AND SERVING AS A PREFACE TO THE SECOND. During the year 186—, the whole world was greatly excited by a scientific experiment unprecedented in the annals of science. The members of the Gun Club, a circle of artillerymen formed at Baltimore after the American war, conceived the idea of putting themselves in communication with the moon!—yes, with the moon,—by sending to her a projectile. Their president, Barbicane, the promoter of the enterprise, having consulted the astronomers of the Cambridge Observatory upon the subject, took all necessary means to ensure the success of this extraordinary enterprise, which had been declared practicable by the majority of competent judges. After setting on foot a public subscription, which realized nearly 1,200,000_l._ they began the gigantic work. According to the advice forwarded from the members of the Observatory, the gun destined to launch the projectile had to be fixed in a country situated between the 0 and 28th degrees of north or south latitude, in order to aim at the moon when at the zenith; and its initiatory velocity was fixed at twelve thousand yards to the second. Launched on the 1st of December, at 10hrs. 46m. 40s. p.m., it ought to reach the moon four days after its departure, that is on the 5th of December, at midnight precisely, at the moment of her attaining her _perigee_, that is her nearest distance from the earth, which is exactly 86,410 leagues (French), or 238,833 miles _mean distance_ (English).
