From the Earth to the Moon, Direct in Ninety-Seven Hours and Twenty Minutes: and a Trip Round It

At this point, under their feet, rose Mount Helicon, 1520 feet high, and round about the left rose moderate elevations, enclosing a small portion of the "Sea of Rains," under the name of the Gulf of Iris. The terrestrial atmosphere would have to be one hundred and seventy times more transparent than it is, to allow astronomers to make perfect observations on the moon's surface; but in the void in which the projectile floated no fluid interposed itself between the eye of the observer and the object observed. And more, Barbicane found himself carried to a greater distance than the most powerful telescopes had ever done before, either that of Lord Rosse or that of the Rocky Mountains. He was, therefore, under extremely favourable conditions for solving that great question of the habitability of the moon; but the solution still escaped him; he could distinguish nothing but desert beds, immense plains, and towards the north, arid mountains. Not a work betrayed the hand of man; not a ruin marked his course; not a group of animals was to be seen indicating life, even in an inferior degree. In no part was there life, in no part was there an appearance of vegetation. Of the three kingdoms which share the terrestrial globe between them, one alone was represented on the lunar and that the mineral.

"Ah, indeed!" said Michel Ardan, a little out of countenance; "then you see no one?"

"No," answered Nicholl; "up to this time not a man, not an animal, not a tree! After all, whether the atmosphere has taken refuge at the bottom of cavities, in the midst of the circles, or even on the opposite face of the moon, we cannot decide."

"Besides," added Barbicane, "even to the most piercing eye a man cannot be distinguished farther than three miles and a half off; so that, if there are any Selenites, they can see our projectile, but we cannot see them."

Towards four in the morning, at the height of the fiftieth parallel, the distance was reduced to 300 miles. To the left ran a line of mountains capriciously shaped, lying in the full light. To the right, on the contrary, lay a black hollow resembling a vast well, unfathomable and gloomy, drilled into the lunar soil.

This hole was the "Black Lake;" it was Pluto, a deep circle which can be conveniently studied from the earth, between the last quarter and the new moon, when the shadows fall from west to east.

This black colour is rarely met with on the surface of the satellite. As yet it has only been recognized in the depths of the circle of Endymion, to the east of the Cold Sea, in the northern hemisphere, and at the bottom of Grimaldi's circle, on the equator, towards the eastern border of the orb.

Pluto is an annular mountain, situated in 51° north latitude, and 9° east longitude. Its circuit is forty-seven miles long and thirty-two broad.

Barbicane regretted that they were not passing directly above this vast opening. There was an abyss to fathom, perhaps some mysterious phenomenon to surprise; but the projectile's course could not be altered. They must rigidly submit. They could not guide a balloon, still less a projectile, when once enclosed within its walls. Towards five in the morning the northern limits of the Sea of Rains was at length passed. The mounts of Condamine and Fontenelle remained – one on the right, the other on the left. That part of the disc beginning with 60° was becoming quite mountainous. The glasses brought them to within two miles, less than that separating the summit of Mont Blanc from the level of the sea. The whole region was bristling with spikes and circles. Towards the 60° Philolaus stood predominant at a height of 5550 feet with its elliptical crater, and seen from this distance, the disc showed a very fantastical appearance. Landscapes were presented to the eye under very different conditions from those on the earth, and also very inferior to them.

The moon having no atmosphere, the consequences arising from the absence of this gaseous envelope have already been shown. No twilight on her surface; night following day and day following night with the suddenness of a lamp which is extinguished or lighted amidst profound darkness, – no transition from cold to heat, the temperature falling in an instant from boiling point to the cold of space.

Another consequence of this want of air is that absolute darkness reigns where the sun's rays do not penetrate. That which on earth is called diffusion of light, that luminous matter which the air holds in suspension, which creates the twilight and the daybreak, which produces the umbræ and the penumbræ, and all the magic of chiaro-oscuro, does not exist on the moon. Hence the harshness of contrasts, which only admit of two colours, black and white. If a Selenite were to shade his eyes from the sun's rays, the sky would seem absolutely black, and the stars would shine to him as on the darkest night. Judge of the impression produced on Barbicane and his three friends by this strange scene! Their eyes were confused. They could no longer grasp the respective distances of the different plains. A lunar landscape without the softening of the phenomena of chiaro-oscuro could not be rendered by an earthly landscape painter: it would be spots of ink on a white page – nothing more.

This aspect was not altered even when the projectile, at the height of 80°, was only separated from the moon by a distance of fifty miles; nor even when, at five in the morning, it passed at less than twenty-five miles from the mountain of Gioja, a distance reduced by the glasses to a quarter of a mile. It seemed as if the moon might be touched by the hand! It seemed impossible that, before long, the projectile would not strike her, if only at the north pole, the brilliant arch of which was so distinctly visible on the black sky.

Michel Ardan wanted to open one of the scuttles and throw himself on to the moon's surface! A very useless attempt; for if the projectile could not attain any point whatever of the satellite, Michel, carried along by its motion, could not attain it either.

At that moment, at six o'clock, the lunar pole appeared. The disc only presented to the travellers' gaze one half brilliantly lit up, whilst the other disappeared in the darkness. Suddenly the projectile passed the line of demarcation between intense light and absolute darkness, and was plunged in profound night!

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, aghast.

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 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 invisible points.

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 travellers being borne away into gloomy space, without their accustomed cortège of rays, felt a vague uneasiness at 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 favoured 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 that diminutive moon that we know; – the earth which develops 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."
