Chapter: At the moment when that pyramid of fire rose to a prodigious
height into the air, the glare of flame lit up the whole of
Florida; and for a moment day superseded night over a
considerable extent of the country.  This immense canopy of fire
was perceived at a distance of one hundred miles out at sea, and
more than one ship's captain entered in his log the appearance
of this gigantic meteor.

The discharge of the Columbiad was accompanied by a
perfect earthquake.  Florida was shaken to its very depths.
The gases of the powder, expanded by heat, forced back the
atmospheric strata with tremendous violence, and this
artificial hurricane rushed like a water-spout through the air.

Not a single spectator remained on his feet!  Men, women
children, all lay prostrate like ears of corn under a tempest.
There ensued a terrible tumult; a large number of persons were
seriously injured.  J. T. Maston, who, despite all dictates of
prudence, had kept in advance of the mass, was pitched back 120
feet, shooting like a projectile over the heads of his
fellow-citizens.  Three hundred thousand persons remained deaf
for a time, and as though struck stupefied.

As soon as the first effects were over, the injured, the deaf,
and lastly, the crowd in general, woke up with frenzied cries.
"Hurrah for Ardan!  Hurrah for Barbicane!  Hurrah for Nicholl!"
rose to the skies.  Thousands of persons, noses in air, armed
with telescopes and race-glasses, were questioning space,
forgetting all contusions and emotions in the one idea of
watching for the projectile.  They looked in vain!  It was no
longer to be seen, and they were obliged to wait for telegrams
from Long's Peak.  The director of the Cambridge Observatory was
at his post on the Rocky Mountains; and to him, as a skillful
and persevering astronomer, all observations had been confided.

But an unforeseen phenomenon came in to subject the public
impatience to a severe trial.

The weather, hitherto so fine, suddenly changed; the sky became
heavy with clouds.  It could not have been otherwise after the
terrible derangement of the atmospheric strata, and the dispersion
of the enormous quantity of vapor arising from the combustion of
200,000 pounds of pyroxyle!

On the morrow the horizon was covered with clouds-- a thick and
impenetrable curtain between earth and sky, which unhappily
extended as far as the Rocky Mountains.  It was a fatality!
But since man had chosen so to disturb the atmosphere, he was
bound to accept the consequences of his experiment.

Supposing, now, that the experiment had succeeded, the travelers
having started on the 1st of December, at 10h. 46m. 40s. P.M.,
were due on the 4th at 0h. P.M. at their destination.  So that
up to that time it would have been very difficult after all to
have observed, under such conditions, a body so small as the shell.
Therefore they waited with what patience they might.

From the 4th to the 6th of December inclusive, the weather
remaining much the same in America, the great European
instruments of Herschel, Rosse, and Foucault, were constantly
directed toward the moon, for the weather was then magnificent;
but the comparative weakness of their glasses prevented any
trustworthy observations being made.

On the 7th the sky seemed to lighten.  They were in hopes now,
but their hope was of but short duration, and at night again
thick clouds hid the starry vault from all eyes.

Matters were now becoming serious, when on the 9th the sun
reappeared for an instant, as if for the purpose of teasing
the Americans.  It was received with hisses; and wounded, no
doubt, by such a reception, showed itself very sparing of its rays.

On the 10th, no change!  J. T. Maston went nearly mad, and great
fears were entertained regarding the brain of this worthy
individual, which had hitherto been so well preserved within his
gutta-percha cranium.

But on the 11th one of those inexplicable tempests peculiar to
those intertropical regions was let loose in the atmosphere.
A terrific east wind swept away the groups of clouds which had
been so long gathering, and at night the semi-disc of the orb of
night rode majestically amid the soft constellations of the sky.

 The launch has some nasty side-effects. For one, there's an earthquake in Florida, which knocks the crowd over "like ears of corn before a storm" . Meanwhile, the sky is now completely "covered with clouds" and doesn't clear up for some time, making it impossible to track to capsule's progress. Finally, the sky clears up, allowing the Gun Club to view their hard work in action.
