moon (applying this designation to our globe) but on one side of
her disc。 Now if this were the case with the earth if; for
example; Europe never saw the moon; and she was only visible at
the antipodes; imagine to yourself the astonishment of a
European on arriving in Australia。〃
〃They would make the voyage for nothing but to see the moon!〃
replied Michel。
〃Very well!〃 continued Barbicane; 〃that astonishment is reserved
for the Selenites who inhabit the face of the moon opposite to
the earth; a face which is ever invisible to our countrymen of
the terrestrial globe。〃
〃And which we should have seen;〃 added Nicholl; 〃if we had arrived
here when the moon was new; that is to say fifteen days later。〃
〃I will add; to make amends;〃 continued Barbicane; 〃that the
inhabitants of the visible face are singularly favored by nature;
to the detriment of their brethren on the invisible face。
The latter; as you see; have dark nights of 354 hours; without
one single ray to break the darkness。 The other; on the contrary;
when the sun which has given its light for fifteen days sinks
below the horizon; see a splendid orb rise on the opposite horizon。
It is the earth; which is thirteen times greater than the
diminutive moon that we know the earth which developes itself
at a diameter of two degrees; and which sheds a light thirteen
times greater than that qualified by atmospheric strata the
earth which only disappears at the moment when the sun reappears
in its turn!〃
〃Nicely worded!〃 said Michel; 〃slightly academical perhaps。〃
〃It follows; then;〃 continued Barbicane; without knitting his
brows; 〃that the visible face of the disc must be very agreeable
to inhabit; since it always looks on either the sun when the
moon is full; or on the earth when the moon is new。〃
〃But;〃 said Nicholl; 〃that advantage must be well compensated by
the insupportable heat which the light brings with it。〃
〃The inconvenience; in that respect; is the same for the two
faces; for the earth's light is evidently deprived of heat。
But the invisible face is still more searched by the heat than
the visible face。 I say that for _you_; Nicholl; because Michel
will probably not understand。〃
〃Thank you;〃 said Michel。
〃Indeed;〃 continued Barbicane; 〃when the invisible face receives
at the same time light and heat from the sun; it is because the
moon is new; that is to say; she is situated between the sun and
the earth。 It follows; then; considering the position which she
occupies in opposition when full; that she is nearer to the sun
by twice her distance from the earth; and that distance may be
estimated at the two…hundredth part of that which separates the
sun from the earth; or in round numbers 400;000 miles。 So that
invisible face is so much nearer to the sun when she receives
its rays。〃
〃Quite right;〃 replied Nicholl。
〃On the contrary;〃 continued Barbicane。
〃One moment;〃 said Michel; interrupting his grave companion。
〃What do you want?〃
〃I ask to be allowed to continue the explanation。〃
〃And why?〃
〃To prove that I understand。〃
〃Get along with you;〃 said Barbicane; smiling。
〃On the contrary;〃 said Michel; imitating the tone and gestures
of the president; 〃on the contrary; when the visible face of the
moon is lit by the sun; it is because the moon is full; that is
to say; opposite the sun with regard to the earth。 The distance
separating it from the radiant orb is then increased in round
numbers to 400;000 miles; and the heat which she receives must
be a little less。〃
〃Very well said!〃 exclaimed Barbicane。 〃Do you know; Michel;
that; for an amateur; you are intelligent。〃
〃Yes;〃 replied Michel coolly; 〃we are all so on the Boulevard
des Italiens。〃
Barbicane gravely grasped the hand of his amiable companion; and
continued to enumerate the advantages reserved for the inhabitants
of the visible face。
Among others; he mentioned eclipses of the sun; which only take
place on this side of the lunar disc; since; in order that they
may take place; it is necessary for the moon to be _in
opposition_。 These eclipses; caused by the interposition of the
earth between the moon and the sun; can last _two hours_; during
which time; by reason of the rays refracted by its atmosphere;
the terrestrial globe can appear as nothing but a black point
upon the sun。
〃So;〃 said Nicholl; 〃there is a hemisphere; that invisible
hemisphere which is very ill supplied; very ill treated;
by nature。〃
〃Never mind;〃 replied Michel; 〃if we ever become Selenites; we
will inhabit the visible face。 I like the light。〃
〃Unless; by any chance;〃 answered Nicholl; 〃the atmosphere should
be condensed on the other side; as certain astronomers pretend。〃
〃That would be a consideration;〃 said Michel。
Breakfast over; the observers returned to their post。 They tried
to see through the darkened scuttles by extinguishing all light
in the projectile; but not a luminous spark made its way through
the darkness。
One inexplicable fact preoccupied Barbicane。 Why; having passed
within such a short distance of the moonabout twenty…five
miles only why the projectile had not fallen? If its speed
had been enormous; he could have understood that the fall would
not have taken place; but; with a relatively moderate speed;
that resistance to the moon's attraction could not be explained。
Was the projectile under some foreign influence? Did some kind
of body retain it in the ether? It was quite evident that it
could never reach any point of the moon。 Whither was it going?
Was it going farther from; or nearing; the disc? Was it being
borne in that profound darkness through the infinity of space?
How could they learn; how calculate; in the midst of this night?
All these questions made Barbicane uneasy; but he could not
solve them。
Certainly; the invisible orb was _there_; perhaps only some few
miles off; but neither he nor his companions could see it。
If there was any noise on its surface; they could not hear it。
Air; that medium of sound; was wanting to transmit the groanings
of that moon which the Arabic legends call 〃a man already half
granite; and still breathing。〃
One must allow that that was enough to aggravate the most
patient observers。 It was just that unknown hemisphere which
was stealing from their sight。 That face which fifteen days
sooner; or fifteen days later; had been; or would be; splendidly
illuminated by the solar rays; was then being lost in utter darkness。
In fifteen days where would the projectile be? Who could say?
Where would the chances of conflicting attractions have drawn
it to? The disappointment of the travelers in the midst of this
utter darkness may be imagined。 All observation of the lunar
disc was impossible。 The constellations alone claimed all their
attention; and we must allow that the astronomers Faye; Charconac;
and Secchi; never found themselves in circumstances so favorable
for their observation。
Indeed; nothing could equal the splendor of this starry world;
bathed in limpid ether。 Its diamonds set in the heavenly vault
sparkled magnificently。 The eye took in the firmament from the
Southern Cross to the North Star; those two constellations which
in 12;000 years; by reason of the succession of equinoxes; will
resign their part of the polar stars; the one to Canopus in the
southern hemisphere; the other to Wega in the northern。
Imagination loses itself in this sublime Infinity; amid which
the projectile was gravitating; like a new star created by the
hand of man。 From a natural cause; these constellations shone
with a soft luster; they did not twinkle; for there was no
atmosphere which; by the intervention of its layers unequally
dense and of different degrees of humidity; produces
this scintillation。 These stars were soft eyes; looking out
into the dark night; amid the silence of absolute space。
Long did the travelers stand mute; watching the constellated
firmament; upon which the moon; like a vast screen; made an
enormous black hole。 But at length a painful sensation drew
them from their watchings。 This was an intense cold; which soon
covered the inside of the glass of the scuttles with a thick
coating of ice。 The sun was no longer warming the projectile
with its direct rays; and thus it was losing the heat stored up
in its walls by degrees。 This heat was rapidly evaporating into
space by radiation; and a considerably lower temperature was
the result。 The humidity of the interior was changed into ice
upon contact with the glass; preventing all observation。
Nicholl consulted the thermometer; and saw that it had fallen to
seventeen degrees (Centigrade) below zero。 '3' So that; in spite
of the many reasons for economizing; Barbicane; after having
begged light from the gas; was also obliged to beg for heat。
The projectile's low temperature was no longer endurable。
Its tenants would have been frozen to death。
'3' 1@ Fahrenheit。
〃Well!〃 observed Michel; 〃we cannot reasonably complain of the
monotony of our journey! What variety we have had; at least
in temperature。 Now we are blinded with light and saturated with
heat; like the Indians of the Pampas! now plunged into profou
