From that day forward Impey Barbicane became one of the greatest citizens of the United States, a kind of Washington of Science. A single trait of feeling, taken from many others, will serve to show the point which this homage of a whole people to a single individual attained. Some few days after this memorable meeting of the Gun Club, the manager of an English company announced, at the Baltimore theatre, the production of "Much ado about Nothing." But the populace, seeing in that title an allusion damaging to Barbicane's project, broke into the auditorium, smashed the benches, and compelled the unlucky director to alter his playbill. Being a sensible man, he bowed to the public will and replaced the offending comedy by "As you like it;" and for many weeks he realized fabulous profits. Illustration: CAMBRIDGE OBSERVATORY. CHAPTER IV. REPLY FROM THE OBSERVATORY OF CAMBRIDGE. Barbicane, however, lost not one moment amidst all the enthusiasm of which he had become the object. His first care was to reassemble his colleagues in the board-room of the Gun Club. There, after some discussion, it was agreed to consult the astronomers regarding the astronomical part of the enterprize. Their reply once ascertained, they could then discuss the mechanical means, and nothing should be wanting to ensure the success of this great experiment. A note couched in precise terms, containing special interrogatories, was then drawn up and addressed to the Observatory of Cambridge in Massachusetts. This city, where the first University of the United States was founded, is justly celebrated for its astronomical staff. There are to be found assembled all the most eminent men of science. Here is to be seen at work that powerful telescope which enabled Bond to resolve the nebula of Andromeda, and Clarke to discover the satellite of Sirius. This celebrated institution fully justified on all points the confidence reposed in it by the Gun Club. So, after two days, the reply so impatiently awaited was placed in the hands of President Barbicane. It was couched in the following terms:— "_The Director of the Cambridge Observatory to the President of the Gun Club at Baltimore._ "CAMBRIDGE, _Oct._ 7. "On the receipt of your favour of the 6th inst., addressed to the Observatory of Cambridge in the name of the Members of the Baltimore Gun Club, our staff was immediately called together, and it was judged expedient to reply as follows:— "The questions which have been proposed to it are these,— "'1. Is it possible to transmit a projectile up to the moon? "'2. What is the exact distance which separates the earth from its satellite? "'3. What will be the period of transit of the projectile when endowed with sufficient initial velocity? and, consequently, at what moment ought it to be discharged in order that it may touch the moon at a particular point?
