CHAPTER XI


FLORIDA AND TEXAS


One question remained yet to be decided; it was necessary to
choose a favorable spot for the experiment. According to the
advice of the Observatory of Cambridge, the gun must be fired
perpendicularly to the plane of the horizon, that is to say,
toward the zenith. Now the moon does not traverse the zenith,
except in places situated between 0@ and 28@ of latitude. It
became, then, necessary to determine exactly that spot on the
globe where the immense Columbiad should be cast.

On the 20th of October, at a general meeting of the Gun Club,
Barbicane produced a magnificent map of the United States.
"Gentlemen," said he, in opening the discussion, "I presume that
we are all agreed that this experiment cannot and ought not to
be tried anywhere but within the limits of the soil of the Union.
Now, by good fortune, certain frontiers of the United States
extend downward as far as the 28th parallel of the north latitude.
