as pitch and round as a crater; it is surrounded by such lofty mountains that their shadows reach clear across, rendering the interior quite invisible!"
"That's Plato;" said M'Nicholl; "I know it well; it's the darkest spot on the Moon: many a night I gazed at it from my little observatory in Broad Street, Philadelphia."
"Right, Captain," said Barbican; "the crater Plato, is, indeed, generally considered the blackest spot on the Moon, but I am inclined to consider the spots Grimaldi and Riccioli on the extreme eastern edge to be somewhat darker. If you take my glass, Ardan, which is of somewhat greater power than yours, you will distinctly see the bottom of the crater. The reflective power of its plateau probably proceeds from the exceedingly great number of small craters that you can detect there."
"I think I see something like them now," said Ardan. "But I am sorry the Projectile's course will not give us a vertical view."
"Can't be helped!" said Barbican; "we must go where it takes us. The day may come when man can steer the projectile or the balloon in which he is shut up, in any way he pleases, but that day has not come yet!"
Towards five in the morning, the northern limit of Mare Imbrium was finally passed, and Mare Frigoris spread its frost-colored plains far to the right and left. On the east the travellers could easily see the ring-mountain Condamine, about 4000 feet high, while a little ahead on the right they could plainly distinguish Fontenelle with an altitude nearly twice as great. Mare Frigoris was soon passed, and the whole lunar surface beneath the travellers, as far as they could see in all directions, now bristled with mountains, crags, and peaks. Indeed, at the 70th parallel the "Seas" or plains seem to have come to an end. The spy-glasses now brought the surface to within about three miles, a distance less than that between the hotel at Chamouni and the summit of Mont Blanc. To the left, they had no difficulty in distinguishing the ramparts of Philolaus, about 12,000 feet high, but though the crater had a diameter of nearly thirty miles, the black shadows prevented the slightest sign of its interior from being seen. The Sun was now sinking very low, and the illuminated surface of the Moon was reduced to a narrow rim.
By this time, too, the bird's eye view to which the observations had so far principally confined, decidedly altered its character. They could now look back at the lunar mountains that they had been just sailing over—a view somewhat like that enjoyed by a tourist standing on the summit of Mt. St. Gothard as he sees the sun setting behind the peaks of the Bernese Oberland. The lunar landscapes however, though seen under these new and ever varying conditions, "hardly gained much by the change," according to Ardan's expression. On the contrary, they looked, if possible, more dreary and inhospitable than before.
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 space. 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-glasses 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 space 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 assuming 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 passed 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
