The Moon having no atmosphere, the benefit of this gaseous envelope in softening off and nicely shading the approaches of light and darkness, heat and cold, is never felt on her surface. There, no twilight ever softly ushers in the brilliant sun, or sweetly heralds the near approach of night"s dark shadow. Night follows day, and day night, with the startling suddenness of a match struck or a lamp extinguished in a cavern. Nor can it present any gradual transition from either extreme of temperature. Hot jumps to cold, and cold jumps to hot. A moment after a glacial midnight, it is a roasting noon. Without an instant"s warning the temperature falls from 212 Fahrenheit to the icy winter of interstellar s.p.a.ce. The surface is all dazzling glare, or pitchy gloom.
Wherever the direct rays of the sun do not fall, darkness reigns supreme. What we call diffused light on Earth, the grateful result of refraction, the luminous matter held in suspension by the air, the mother of our dawns and our dusks, of our blushing mornings and our dewy eyes, of our shades, our penumbras, our tints and all the other magical effects of _chiaro-oscuro_--this diffused light has absolutely no existence on the surface of the Moon. Nothing is there to break the inexorable contrast between intense white and intense black. At mid-day, let a Selenite shade his eyes and look at the sky: it will appear to him as black as pitch, while the stars still sparkle before him as vividly as they do to us on the coldest and darkest night in winter.
From this you can judge of the impression made on our travellers by those strange lunar landscapes. Even their decided novelty and very strange character produced any thing but a pleasing effect on the organs of sight. With all their enthusiasm, the travellers felt their eyes "get out of gear," as Ardan said, like those of a man blind from his birth and suddenly restored to sight. They could not adjust them so as to be able to realize the different plains of vision. All things seemed in a heap. Foreground and background were indistinguishably commingled. No painter could ever transfer a lunar landscape to his canvas.
"Landscape," Ardan said; "what do you mean by a landscape? Can you call a bottle of ink intensely black, spilled over a sheet of paper intensely white, a landscape?"
At the eightieth degree, when the Projectile was hardly 100 miles distant from the Moon, the aspect of things underwent no improvement. On the contrary, the nearer the travellers approached the lunar surface, the drearier, the more inhospitable, and the more _unearthly_, everything seem to look. Still when five o"clock in the morning brought our travellers to within 50 miles of _Mount Gioja_--which their spy-gla.s.ses rendered as visible as if it was only about half a mile off, Ardan could not control himself.
"Why, we"re there" he exclaimed; "we can touch her with our hands! Open the windows and let me out! Don"t mind letting me go by myself. It is not very inviting quarters I admit. But as we are come to the jumping off place, I want to see the whole thing through. Open the lower window and let me out. I can take care of myself!"
"That"s what"s more than any other man can do," said M"Nicholl drily, "who wants to take a jump of 50 miles!"
"Better not try it, friend Ardan," said Barbican grimly: "think of Satellite! The Moon is no more attainable by your body than by our Projectile. You are far more comfortable in here than when floating about in empty s.p.a.ce like a bolide."
Ardan, unwilling to quarrel with his companions, appeared to give in; but he secretly consoled himself by a hope which he had been entertaining for some time, and which now looked like a.s.suming the appearance of a certainty. The Projectile had been lately approaching the Moon"s surface so rapidly that it at last seemed actually impossible not to finally touch it somewhere in the neighborhood of the north pole, whose dazzling ridges now presented themselves in sharp and strong relief against the black sky. Therefore he kept silent, but quietly bided his time.
The Projectile moved on, evidently getting nearer and nearer to the lunar surface. The Moon now appeared to the travellers as she does to us towards the beginning of her Second Quarter, that is as a bright crescent instead of a hemisphere. On one side, glaring dazzling light; on the other, cavernous pitchy darkness. The line separating both was broken into a thousand bits of protuberances and concavities, dented, notched, and jagged.
At six o"clock the travellers found themselves exactly over the north pole. They were quietly gazing at the rapidly shifting features of the wondrous view unrolling itself beneath them, and were silently wondering what was to come next, when, suddenly, the Projectile pa.s.sed the dividing line. The Sun and Moon instantly vanished from view. The next moment, without the slightest warning the travellers found themselves plunged in an ocean of the most appalling darkness!
CHAPTER XIV.
A NIGHT OF FIFTEEN DAYS.
The Projectile being not quite 30 miles from the Moon"s north pole when the startling phenomenon, recorded in our last chapter, took place, a few seconds were quite sufficient to launch it at once from the brightest day into the unknown realms of night. The transition was so abrupt, so unexpected, without the slightest shading off, from dazzling effulgence to Cimmerian gloom, that the Moon seemed to have been suddenly extinguished like a lamp when the gas is turned off.
"Where"s the Moon?" cried Ardan in amazement.
"It appears as if she had been wiped out of creation!" cried M"Nicholl.
Barbican said nothing, but observed carefully. Not a particle, however, could he see of the disc that had glittered so resplendently before his eyes a few moments ago. Not a shadow, not a gleam, not the slightest vestige could he trace of its existence. The darkness being profound, the dazzling splendor of the stars only gave a deeper blackness to the pitchy sky. No wonder. The travellers found themselves now in a night that had plenty of time not only to become black itself, but to steep everything connected with it in palpable blackness. This was the night 354-1/4 hours long, during which the invisible face of the Moon is turned away from the Sun. In this black darkness the Projectile now fully partic.i.p.ated. Having plunged into the Moon"s shadow, it was as effectually cut off from the action of the solar rays as was every point on the invisible lunar surface itself.
The travellers being no longer able to see each other, it was proposed to light the gas, though such an unexpected demand on a commodity at once so scarce and so valuable was certainly disquieting. The gas, it will be remembered, had been intended for heating alone, not illumination, of which both Sun and Moon had promised a never ending supply. But here both Sun and Moon, in a single instant vanished from before their eyes and left them in Stygian darkness.
"It"s all the Sun"s fault!" cried Ardan, angrily trying to throw the blame on something, and, like every angry man in such circ.u.mstances, bound to be rather nonsensical.
"Put the saddle on the right horse, Ardan," said M"Nicholl patronizingly, always delighted at an opportunity of counting a point off the Frenchman. "You mean it"s all the Moon"s fault, don"t you, in setting herself like a screen between us and the Sun?"
"No, I don"t!" cried Ardan, not at all soothed by his friend"s patronizing tone, and sticking like a man to his first a.s.sertion right or wrong. "I know what I say! It will be all the Sun"s fault if we use up our gas!"
"Nonsense!" said M"Nicholl. "It"s the Moon, who by her interposition has cut off the Sun"s light."
"The Sun had no business to allow it to be cut off," said Ardan, still angry and therefore decidedly loose in his a.s.sertions.
Before M"Nicholl could reply, Barbican interposed, and his even voice was soon heard pouring balm on the troubled waters.
"Dear friends," he observed, "a little reflection on either side would convince you that our present situation is neither the Moon"s fault nor the Sun"s fault. If anything is to be blamed for it, it is our Projectile which, instead of rigidly following its allotted course, has awkwardly contrived to deviate from it. However, strict justice must acquit even the Projectile. It only obeyed a great law of nature in shifting its course as soon as it came within the sphere of that inopportune bolide"s influence."
"All right!" said Ardan, as usual in the best of humor after Barbican had laid down the law. "I have no doubt it is exactly as you say; and, now that all is settled, suppose we take breakfast. After such a hard night spent in work, a little refreshment would not be out of place!"
Such a proposition being too reasonable even for M"Nicholl to oppose, Ardan turned on the gas, and had everything ready for the meal in a few minutes. But, this time, breakfast was consumed in absolute silence. No toasts were offered, no hurrahs were uttered. A painful uneasiness had seized the hearts of the daring travellers. The darkness into which they were so suddenly plunged, told decidedly on their spirits. They felt almost as if they had been suddenly deprived of their sight. That thick, dismal savage blackness, which Victor Hugo"s pen is so fond of occasionally revelling in, surrounded them on all sides and crushed them like an iron shroud.
It was felt worse than ever when, breakfast being over, Ardan carefully turned off the gas, and everything within the Projectile was as dark as without. However, though they could not see each other"s faces, they could hear each other"s voices, and therefore they soon began to talk.
The most natural subject of conversation was this terrible night 354 hours long, which the laws of nature have imposed on the Lunar inhabitants. Barbican undertook to give his friends some explanation regarding the cause of the startling phenomenon, and the consequences resulting from it.
"Yes, startling is the word for it," observed Barbican, replying to a remark of Ardan"s; "and still more so when we reflect that not only are both lunar hemispheres deprived, by turns, of sun light for nearly 15 days, but that also the particular hemisphere over which we are at this moment floating is all that long night completely deprived of earth-light. In other words, it is only one side of the Moon"s disc that ever receives any light from the Earth. From nearly every portion of one side of the Moon, the Earth is always as completely absent as the Sun is from us at midnight. Suppose an a.n.a.logous case existed on the Earth; suppose, for instance, that neither in Europe, Asia or North America was the Moon ever visible--that, in fact, it was to be seen only at our antipodes. With what astonishment should we contemplate her for the first time on our arrival in Australia or New Zealand!"
"Every man of us would pack off to Australia to see her!" cried Ardan.
"Yes," said M"Nicholl sententiously; "for a visit to the South Sea a Turk would willingly forego Mecca; and a Bostonian would prefer Sidney even to Paris."
"Well," resumed Barbican, "this interesting marvel is reserved for the Selenite that inhabits the side of the Moon which is always turned away from our globe."
"And which," added the Captain, "we should have had the unspeakable satisfaction of contemplating if we had only arrived at the period when the Sun and the Earth are not at the same side of the Moon--that is, 15 days sooner or later than now."
"For my part, however," continued Barbican, not heeding these interruptions, "I must confess that, notwithstanding the magnificent splendor of the spectacle when viewed for the first time by the Selenite who inhabits the dark side of the Moon, I should prefer to be a resident on the illuminated side. The former, when his long, blazing, roasting, dazzling day is over, has a night 354 hours long, whose darkness, like that, just now surrounding us, is ever unrelieved save by the cold cheerless rays of the stars. But the latter has hardly seen his fiery sun sinking on one horizon when he beholds rising on the opposite one an orb, milder, paler, and colder indeed than the Sun, but fully as large as thirteen of our full Moons, and therefore shedding thirteen times as much light. This would be our Earth. It would pa.s.s through all its phases too, exactly like our Satellite. The Selenites would have their New Earth, Full Earth, and Last Quarter. At midnight, grandly illuminated, it would shine with the greatest glory. But that is almost as much as can be said for it. Its futile heat would but poorly compensate for its superior radiance. All the calorie acc.u.mulated in the lunar soil during the 354 hours day would have by this time radiated completely into s.p.a.ce. An intensity of cold would prevail, in comparison to which a Greenland winter is tropical. The temperature of interstellar s.p.a.ce, 250 below zero, would be reached. Our Selenite, heartily tired of the cold pale Earth, would gladly see her sink towards the horizon, waning as she sank, till at last she appeared no more than half full.
Then suddenly a faint rim of the solar orb reveals itself on the edge of the opposite sky. Slowly, more than 14 times more slowly than with us, does the Sun lift himself above the lunar horizon. In half an hour, only half his disc is revealed, but that is more than enough to flood the lunar landscape with a dazzling intensity of light, of which we have no counterpart on Earth. No atmosphere refracts it, no hazy screen softens it, no enveloping vapor absorbs it, no obstructing medium colors it. It breaks on the eye, harsh, white, dazzling, blinding, like the electric light seen a few yards off. As the hours wear away, the more blasting becomes the glare; and the higher he rises in the black sky, but slowly, slowly. It takes him seven of our days to reach the meridian. By that time the heat has increased from an arctic temperature to double the boiling water point, from 250 below zero to 500 above it, or the point at which tin melts. Subjected to these extremes, the gla.s.sy rocks crack, shiver and crumble away; enormous land slides occur; peaks topple over; and tons of debris, crashing down the mountains, are swallowed up forever in the yawing chasms of the bottomless craters."
"Bravo!" cried Ardan, clapping his hands softly: "our President is sublime! He reminds me of the overture of _Guillaume Tell_!"
"Souvenir de Marston!" growled M"Nicholl.
"These phenomena," continued Barbican, heedless of interruption and his voice betraying a slight glow of excitement, "these phenomena going on without interruption from month to month, from year to year, from age to age, from _eon_ to _eon_, have finally convinced me that--what?" he asked his hearers, interrupting himself suddenly.
--"That the existence at the present time--" answered M"Nicholl.
--"Of either animal or vegetable life--" interrupted Ardan.
--"In the Moon is hardly possible!" cried both in one voice.
"Besides?" asked Barbican: "even if there _is_ any life--?"
--"That to live on the dark side would be much more inconvenient than on the light side!" cried M"Nicholl promptly.
--"That there is no choice between them!" cried Ardan just as ready.
"For my part, I should think a residence on Mt. Erebus or in Grinnell Land a terrestrial paradise in comparison to either. The _Earth shine_ might illuminate the light side of the Moon a little during the long night, but for any practical advantage towards heat or life, it would be perfectly useless!"
"But there is another serious difference between the two sides," said Barbican, "in addition to those enumerated. The dark side is actually more troubled with excessive variations of temperature than the light one."
"That a.s.sertion of our worthy President," interrupted Ardan, "with all possible respect for his superior knowledge, I am disposed to question."
"It"s as clear as day!" said Barbican.
"As clear as mud, you mean, Mr. President;" interrupted Ardan, "the temperature of the light side is excited by two objects at the same time, the Earth and the Sun, whereas--"
