Chapter XIV. The Night of Three Hundred and Fifty-Four Hours and a Half
At the moment when this phenomenon took place so rapidly, the
projectile was skirting the moon’s north pole at less than
twenty-five miles distance. Some seconds had sufficed to plunge it
into the absolute darkness of space. The transition was so sudden,
without shade, without gradation of light, without attenuation of
the luminous waves, that the orb seemed to have been extinguished
by a powerful blow.
“Melted, disappeared!” Michel Ardan exclaimed,
Indeed, there was neither reflection nor shadow. Nothing more
was to be seen of that disc, formerly so dazzling. The darkness was
complete. and rendered even more so by the rays from the stars. It
was “that blackness” in which the lunar nights are
insteeped, which last three hundred and fifty-four hours and a half
at each point of the disc, a long night resulting from the equality
of the translatory and rotary movements of the moon. The
projectile, immerged in the conical shadow of the satellite,
experienced the action of the solar rays no more than any of its
In the interior, the obscurity was complete. They could not see
each other. Hence the necessity of dispelling the darkness. However
desirous Barbicane might be to husband the gas, the reserve of
which was small, he was obliged to ask from it a fictitious light,
an expensive brilliancy which the sun then refused.
“Devil take the radiant orb!” exclaimed Michel
Ardan, “which forces us to expend gas, instead of giving us
his rays gratuitously.”
“Do not let us accuse the sun,” said Nicholl,
“it is not his fault, but that of the moon, which has come
and placed herself like a screen between us and it.”
“It is the sun!” continued Michel.
“It is the moon!” retorted Nicholl.
An idle dispute, which Barbicane put an end to by saying:
“My friends, it is neither the fault of the sun nor of the
moon; it is the fault of the projectile, which, instead of rigidly
following its course, has awkwardly missed it. To be more just, it
is the fault of that unfortunate meteor which has so deplorably
altered our first direction.”
“Well,” replied Michel Ardan, “as the matter
is settled, let us have breakfast. After a whole night of watching
it is fair to build ourselves up a little.”
This proposal meeting with no contradiction, Michel prepared the
repast in a few minutes. But they ate for eating’s sake, they
drank without toasts, without hurrahs. The bold travelers being
borne away into gloomy space, without their accustomed cortege of
rays, felt a vague uneasiness in their hearts. The
“strange” shadow so dear to Victor Hugo’s pen
bound them on all sides. But they talked over the interminable
night of three hundred and fifty-four hours and a half, nearly
fifteen days, which the law of physics has imposed on the
inhabitants of the moon.
Barbicane gave his friends some explanation of the causes and
the consequences of this curious phenomenon.
“Curious indeed,” said they; “for, if each
hemisphere of the moon is deprived of solar light for fifteen days,
that above which we now float does not even enjoy during its long
night any view of the earth so beautifully lit up. In a word she
has no 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
“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
“But,” said Nicholl, “that advantage must be
well compensated by the insupportable heat which the light brings
“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
“What do you want?”
“I ask to be allowed to continue the
“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
“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
One inexplicable fact preoccupied Barbicane. Why, having passed
within such a short distance of the moon—about 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
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 profound darkness, amid the cold, like the Esquimaux of the
north pole. No, indeed! we have no right to complain; nature does
wonders in our honor.”
“But,” asked Nicholl, “what is the temperature
“Exactly that of the planetary space,” replied
“Then,” continued Michel Ardan, “would not
this be the time to make the experiment which we dared not attempt
when we were drowned in the sun’s rays?
“It is now or never,” replied Barbicane, “for
we are in a good position to verify the temperature of space, and
see if Fourier or Pouillet’s calculations are
“In any case it is cold,” said Michel. “See!
the steam of the interior is condensing on the glasses of the
scuttles. If the fall continues, the vapor of our breath will fall
in snow around us.”
“Let us prepare a thermometer,” said Barbicane.
We may imagine that an ordinary thermometer would afford no
result under the circumstances in which this instrument was to be
exposed. The mercury would have been frozen in its ball, as below
42° Fahrenheit below zero it is no longer liquid. But Barbicane had
furnished himself with a spirit thermometer on Wafferdin’s
system, which gives the minima of excessively low temperatures.
Before beginning the experiment, this instrument was compared
with an ordinary one, and then Barbicane prepared to use it.
“How shall we set about it?” asked Nicholl.
“Nothing is easier,” replied Michel Ardan, who was
never at a loss. “We open the scuttle rapidly; throw out the
instrument; it follows the projectile with exemplary docility; and
a quarter of an hour after, draw it in.”
“With the hand?” asked Barbicane.
“With the hand,” replied Michel.
“Well, then, my friend, do not expose yourself,”
answered Barbicane, “for the hand that you draw in again will
be nothing but a stump frozen and deformed by the frightful
“You will feel as if you had had a terrible burn, like
that of iron at a white heat; for whether the heat leaves our
bodies briskly or enters briskly, it is exactly the same thing.
Besides, I am not at all certain that the objects we have thrown
out are still following us.”
“Why not?” asked Nicholl.
“Because, if we are passing through an atmosphere of the
slightest density, these objects will be retarded. Again, the
darkness prevents our seeing if they still float around us. But in
order not to expose ourselves to the loss of our thermometer, we
will fasten it, and we can then more easily pull it back
Barbicane’s advice was followed. Through the scuttle
rapidly opened, Nicholl threw out the instrument, which was held by
a short cord, so that it might be more easily drawn up. The scuttle
had not been opened more than a second, but that second had
sufficed to let in a most intense cold.
“The devil!” exclaimed Michel Ardan, “it is
cold enough to freeze a white bear.”
Barbicane waited until half an hour had elapsed, which was more
than time enough to allow the instrument to fall to the level of
the surrounding temperature. Then it was rapidly pulled in.
Barbicane calculated the quantity of spirits of wine overflowed
into the little vial soldered to the lower part of the instrument,
“A hundred and forty degrees Centigrade 4 below
4 218 degrees Fahrenheit below zero.
M. Pouillet was right and Fourier wrong. That was the undoubted
temperature of the starry space. Such is, perhaps, that of the
lunar continents, when the orb of night has lost by radiation all
the heat which fifteen days of sun have poured into her.
