<h3 id="sigil_toc_id_42">ATTACK AND RIPOSTE.</h3>
<p>As soon as the excitement had subsided, the following words were
heard uttered in a strong and determined voice:—</p>
<p>"Now that the speaker has favoured us with so much imagination,
would he be so good as to return to his subject, and give us a little
practical view of the question?"</p>
<p>All eyes were directed towards the person who spoke. He was a
little dried-up man, of an active figure, with an American "goatee"
beard. Profiting by the different movements in the crowd, he had
managed by degrees to gain the front row of spectators. There, with
arms crossed and stern gaze, he watched the hero of the meeting.
After having put his question he remained silent, and appeared to
take no notice of the thousands of looks directed towards himself,
nor of the murmur of disapprobation excited by his words. Meeting at
first with no reply, he repeated his question with marked emphasis,
adding, "We are here to talk about the <i>moon</i> and not about the
<i>earth</i>."</p>
<p>"You are right, sir," replied Michel Ardan; "the discussion has
become irregular. We will return to the moon."</p>
<p>"Sir," said the unknown, "you pretend that our satellite is
inhabited. Very good; but if Selenites do exist, that race of beings
assuredly must live without breathing, for—I warn you for your own
sake—there is not the smallest particle of air on the surface of the
moon."</p>
<p>At this remark Ardan pushed up his shock of red hair; he saw that
he was on the point of being involved in a struggle with this person
upon the very gist of the whole question. He looked sternly at him in
his turn and said,—</p>
<p>"Oh! so there is no air in the moon? And pray, if you are so good,
who ventures to affirm that?"</p>
<p>"The men of science."</p>
<p>"Really?"</p>
<p>"Really."</p>
<p>"Sir," replied Michel, "pleasantry apart, I have a profound
respect for men of science who do possess science, but a profound
contempt for men of science who do not."</p>
<p>"Do you know any who belong to the latter category?"</p>
<p>"Decidedly. In France there are some who maintain that,
mathematically, a bird cannot possibly fly; and others who
demonstrate theoretically that fishes were never made to live in
water."</p>
<p>"I have nothing to do with persons of that description, and I can
quote, in support of my statement, names which you cannot refuse
deference to."</p>
<p>"Then, sir, you will sadly embarrass a poor ignorant, who,
besides, asks nothing better than to learn."</p>
<p>"Why, then, do you introduce scientific questions if you have
never studied them?" asked the unknown somewhat coarsely.</p>
<p>"For the reason that 'he is always brave who never suspects
danger.' I know nothing, it is true; but it is precisely my very
weakness which constitutes my strength."</p>
<p>"Your weakness amounts to folly," retorted the unknown in a
passion.</p>
<p>"All the better," replied our Frenchman, "if it carries me up to
the <i>moon.</i>"</p>
<p>Barbicane and his colleagues devoured with their eyes the intruder
who had so boldly placed himself in antagonism to their enterprise.
Nobody knew him, and the president, uneasy as to the result of so
free a discussion, watched his new friend with some anxiety. The
meeting began to be somewhat fidgety also, for the contest directed
their attention to the dangers, if not the actual impossibilities, of
the proposed expedition.</p>

<div class="caption">ATTACK AND RIPOSTE.</div>
<p>"Sir," replied Ardan's antagonist, "there are many and
incontrovertible reasons which prove the absence of an atmosphere in
the moon. I might say that, <i>à priori</i>, if one ever did exist,
it must have been absorbed by the earth; but I prefer to bring
forward indisputable facts."</p>
<p>"Bring them forward then, sir, as many as you please."</p>
<p>"You know," said the stranger, "that when any luminous rays cross
a medium such as the air, they are deflected out of the straight
line; in other words, they undergo <i>refraction.</i> Well! When
stars are occulted by the moon, their rays, on grazing the edge of
her disc, exhibit not the least deviation, nor offer the slightest
indication of refraction. It follows, therefore, that the moon cannot
be surrounded by an atmosphere."</p>
<p>"In point of fact," replied Ardan, "this is your chief, if not
your <i>only</i> argument; and a really scientific man might be
puzzled to answer it. For myself, I will simply say that it is
defective, because it assumes that the angular diameter of the moon
has been completely determined, which is not the case. But let us
proceed. Tell me, my dear sir, do you admit the existence of
volcanoes on the moon's surface?"</p>
<p>"<i>Extinct</i>, yes! In activity, no!"</p>
<p>"These volcanoes, however, were at one time in a state of
activity?"</p>
<p>"True! but, as they furnished themselves the oxygen necessary for
combustion, the mere fact of their eruption does not prove the
presence of an atmosphere."</p>
<p>"Proceed again, then; and let us set aside this class of arguments
in order to come to direct observations. In 1715 the astronomers
Louville and Halley, watching the eclipse of the 3rd May, remarked
some very extraordinary scintillations. These jets of light, rapid in
nature, and of frequent recurrence, they attributed to thunderstorms
generated in the lunar atmosphere."</p>
<p>"In 1715," replied the unknown, "the astronomers Louville and
Halley mistook for lunar phenomena some which were purely
terrestrial, such as meteoric or other bodies which are generated in
our own atmosphere. This was the scientific explanation at the time
of the facts; and that is my answer now."</p>
<p>"On again, then," replied Ardan; "Herschel, in 1787, observed a
great number of luminous points on the moon's surface, did he
not?"</p>
<p>"Yes! but without offering any solution of them. Herschel himself
never inferred from them the necessity of a lunar atmosphere. And I
may add that Bœer and Moedler, the two great authorities upon the
moon, are quite agreed as to the entire absence of air on its
surface."</p>
<p>A movement was here manifest among the assemblage, who appeared to
be growing excited by the arguments of this singular personage.</p>
<p>"Let us proceed," replied Ardan, with perfect coolness, "and come
to one important fact. A skilful French astronomer, M. Laussedat, in
watching the eclipse of July 18, 1860, proved that the horns of the
solar crescent were <i>rounded and truncated.</i> Now, this
appearance could only have been produced by a deviation of the solar
rays in traversing the atmosphere of the moon. There is no other
possible explanation of the fact."</p>
<p>"But is this established as a fact?"</p>
<p>"Absolutely certain!"</p>
<p>A counter-movement here took place in favour of the hero of the
meeting, whose opponent was now reduced to silence. Ardan resumed the
conversation; and without exhibiting any exultation at the advantage
he had gained, simply said,—</p>
<p>"You see, then, my dear sir, we must not pronounce with absolute
positiveness against the existence of an atmosphere in the moon. That
atmosphere is, probably, of extreme rarity; nevertheless at the
present day science generally admits that it exists."</p>
<p>"Not in the mountains, at all events," returned the unknown,
unwilling to give in.</p>
<p>"No! but at the bottom of the valleys, and not exceeding a few
hundred feet in height."</p>
<p>"In any case you will do well to take every precaution, for the
air will be terribly rarified."</p>
<p>"My good sir, there will always be enough for a solitary
individual; besides, once arrived up there, I shall do my best to
economize, and not to breathe except on grand occasions!"</p>
<p>A tremendous roar of laughter rang in the ears of the mysterious
interlocutor, who glared fiercely round upon the assembly.</p>
<p>"Then," continued Ardan, with a careless air, "since we are in
accord regarding the presence of a certain atmosphere, we are forced
to admit the presence of a certain quantity of water. This is a happy
consequence for me. Moreover, my amiable contradictor, permit me to
submit to you one further observation. We only know one side of the
moon's disc; and if there is but little air on the face presented to
us, it is possible that there is plenty on the one turned away from
us."</p>
<p>"And for what reason?"</p>
<p>"Because the moon, under the action of the earth's attraction, has
assumed the form of an egg, which we look at from the smaller end.
Hence it follows, by Hausen's calculations, that its centre of
gravity is situated in the other hemisphere. Hence it results that
the great mass of air and water must have been drawn away to the
other face of our satellite during the first days of its
creation."</p>
<p>"Pure fancies!" cried the unknown.</p>
<p>"No! Pure theories! which are based upon the laws of mechanics,
and it seems difficult to me to refute them. I appeal then to this
meeting, and I put it to them whether life, such as exists upon the
earth, is possible on the surface of the moon?"</p>
<p>Three hundred thousand auditors at once applauded the proposition.
Ardan's opponent tried to get in another word, but he could not
obtain a hearing. Cries and menaces fell upon him like hail.</p>
<p>"Enough! enough!" cried some.</p>
<p>"Drive the intruder off!" shouted others.</p>
<p>"Turn him out!" roared the exasperated crowd.</p>
<p>But he, holding firmly on to the platform, did not budge an inch,
and let the storm pass on, which would soon have assumed formidable
proportions, if Michel Ardan had not quieted it by a gesture. He was
too chivalrous to abandon his opponent in an apparent extremity.</p>
<p>"You wished to say a few more words?" he asked, in a pleasant
voice.</p>
<p>"Yes, a thousand; or rather, no, only one! If you persevere in
your enterprise, you must be a—"</p>
<p>"Very rash person! How can you treat me as such? me, who have
demanded a cylindro-conical projectile, in order to prevent turning
round and round on my way like a squirrel?"</p>
<p>"But, unhappy man, the dreadful recoil will smash you to pieces at
your starting."</p>
<p>"My dear contradictor, you have just put your finger upon the true
and the only difficulty; nevertheless, I have too good an opinion of
the industrial genius of the Americans not to believe that they will
succeed in overcoming it."</p>
<p>"But the heat developed by the rapidity of the projectile in
crossing the strata of air?"</p>
<p>"Oh! the walls are thick, and I shall soon have crossed the
atmosphere."</p>
<p>"But victuals and water?"</p>
<p>"I have calculated for a twelvemonth's supply, and I shall be only
four days on the journey."</p>
<p>"But for air to breathe on the road?"</p>
<p>"I shall make it by chemical process."</p>
<p>"But your fall on the moon, supposing you ever reach it?"</p>
<p>"It will be six times less dangerous than a sudden fall upon the
earth, because the weight will be only one-sixth as great on the
surface of the moon."</p>
<p>"Still it will be enough to smash you like glass!"</p>
<p>"What is to prevent my retarding the shock by means of rockets
conveniently placed, and lighted at the right moment?"</p>
<p>"But after all, supposing all difficulties surmounted, all
obstacles removed, supposing everything combined to favour you, and
granting that you may arrive safe and sound in the moon, how will you
come back?"</p>
<p>"I am not coming back!"</p>
<p>At this reply, almost sublime in its very simplicity, the assembly
became silent. But its silence was more eloquent than could have been
its cries of enthusiasm. The unknown profited by the opportunity and
once more protested,—</p>
<p>"You will inevitably kill yourself!" he cried; "and your death
will be that of a madman, useless even to science!"</p>
<p>"Go on, my dear unknown, for truly your prophecies are most
agreeable!"</p>
<p>"It really is too much!" cried Michel Ardan's adversary. "I do not
know why I should continue so frivolous a discussion! Please yourself
about this insane expedition! We need not trouble ourselves about
you!"</p>
<p>"Pray don't stand upon ceremony!"</p>
<p>"No! another person is responsible for your act."</p>
<p>"Who, may I ask?" demanded Michel Ardan in an imperious tone.</p>
<p>"The ignoramus who organized this equally absurd and impossible
experiment!"</p>
<p>The attack was direct. Barbicane, ever since the interference of
the unknown, had been making fearful efforts of self-control; now,
however, seeing himself directly attacked, he could restrain himself
no longer. He rose suddenly, and was rushing upon the enemy who thus
braved him to the face, when all at once he found himself separated
from him.</p>
<p>The platform was lifted by a hundred strong arms, and the
President of the Gun Club shared with Michel Ardan triumphal honours.
The shield was heavy, but the bearers came in continuous relays,
disputing, struggling, even fighting among themselves in their
eagerness to lend their shoulders to this demonstration.</p>
<p>However, the unknown had not profited by the tumult to quit his
post. Besides he could not have done it in the midst of that compact
crowd. There he held on in the front row with crossed arms, glaring
at President Barbicane.</p>
<p>The shouts of the immense crowd continued at their highest pitch
throughout this triumphant march. Michel Ardan took it all with
evident pleasure. His face gleamed with delight. Several times the
platform seemed seized with pitching and rolling like a
weather-beaten ship. But the two heroes of the meeting had good
sea-legs. They never stumbled; and their vessel arrived without dues
at the port of Tampa Town.</p>
<p>Michel Ardan managed fortunately to escape from the last embraces
of his vigorous admirers. He made for the Hotel Franklin, quickly
gained his chamber, and slid under the bedclothes, while an army of a
hundred thousand men kept watch under his windows.</p>
<p>During this time a scene, short, grave, and decisive, took place
between the mysterious personage and the President of the Gun
Club.</p>
<p>Barbicane, free at last, had gone straight at his adversary.</p>
<p>"Come!" he said shortly.</p>
<p>The other followed him on to the quay; and the two presently found
themselves alone at the entrance of an open wharf on Jones' Fall.</p>
<p>The two enemies, still mutually unknown, gazed at each other.</p>
<p>"Who are you?" asked Barbicane.</p>
<div class="illus"><ANTIMG alt="Illustration: THE PLATFORM WAS SUDDENLY CARRIED AWAY." id="platform"

<div class="caption">THE PLATFORM WAS SUDDENLY CARRIED AWAY.</div>
<p>"Captain Nicholl!"</p>
<p>"So I suspected. Hitherto chance has never thrown you in my
way."</p>
<p>"I am come for that purpose."</p>
<p>"You have insulted me."</p>
<p>"Publicly!"</p>
<p>"And you will answer to me for this insult?"</p>
<p>"At this very moment."</p>
<p>"No! I desire that all that passes between us shall be secret.
There is a wood situated three miles from Tampa, the wood of
Skersnaw. Do you know it?"</p>
<p>"I know it."</p>
<p>"Will you be so good as to enter it to-morrow morning at five
o'clock, on one side?"</p>
<p>"Yes! if you will enter at the other side at the same hour."</p>
<p>"And you will not forget your rifle?" said Barbicane.</p>
<p>"No more than you will forget yours," replied Nicholl.</p>
<p>These words having been coldly spoken, the President of the Gun
Club and the captain parted. Barbicane returned to his lodging; but
instead of snatching a few hours of repose, he passed the night in
endeavouring to discover a means of evading the recoil of the
projectile, and resolving the difficult problem proposed by Michel
Ardan during the discussion at the meeting.</p>
