354 hours long."

"Well! if anything could surprise me," said Ardan quickly, "such an assertion as that most certainly would. On what does the honorable gentleman base his most firm conviction?"

"We know," replied the Captain, "that the reason of the Moon's present long day and night is the exact equality of the periods of her rotation on her axis and of her revolution around the Earth. When she has turned once around the Earth, she has turned once around herself. Consequently, her back is turned to the Sun during one-half of the month; and her face during the other half. Now, I don't believe that this state of things existed at the period referred to."

"The gentleman does not believe!" exclaimed Ardan. "The Chair must be excused for reminding the honorable gentleman that it can not accept his incredulity as a sound and valid argument. These two movements have certainly equal periods now; why not always?"

"For the simple reason that this equality of periods is due altogether to the influence of terrestrial attraction," replied the ready Captain. "This attraction at present, I grant, is so great that it actually disables the Moon from revolving on herself; consequently she must always keep the same face turned towards the Earth. But who can assert that this attraction was powerful enough to exert the same influence at the epoch when the Earth herself was only a fluid substance? In fact, who can even assert that the Moon has always been the Earth's satellite?"

"Ah, who indeed?" exclaimed Ardan. "And who can assert that the Moon did not exist long before the Earth was called into being at all? In fact, who can assert that the Earth itself is not a great piece broken off the Moon? Nothing like asking absurd questions! I've often found them passing for the best kind of arguments!"

"Friend Ardan," interposed Barbican, who noticed that the Captain was a little too disconcerted to give a ready reply; "Friend Ardan, I must say you are not quite wrong in showing how certain methods of reasoning, legitimate enough in themselves, may be easily abused by being carried too far. I think, however, that the Captain might maintain his position without having recourse to speculations altogether too gigantic for ordinary intellect. By simply admitting the insufficiency of the primordeal attraction to preserve a perfect balance between the movements of the lunar rotation and revolution, we can easily see how the nights and days could once succeed each other on the Moon exactly as they do at present on the Earth."

"Nothing can be clearer!" resumed the brave Captain, once more rushing to the charge. "Besides, even without this alternation of days and nights, life on the lunar surface was quite possible."

"Of course it was possible," said Ardan; "everything is possible except what contradicts itself. It is possible too that every possibility is a fact; therefore, it is a fact. However," he added, not wishing to press the Captain's weak points too closely, "let all these logical niceties pass for the present. Now that you have established the existence of your humanity in the Moon, the Chair would respectfully ask how it has all so completely disappeared?"

"It disappeared completely thousands, perhaps millions, of years ago," replied the unabashed Captain. "It perished from the physical impossibility of living any longer in a world where the atmosphere had become by degrees too rare to be able to perform its functions as the great resuscitating medium of dependent existences. What took place on the Moon is only what is to take place some day or other on the Earth, when it is sufficiently cooled off."

"Cooled off?"

"Yes," replied the Captain as confidently and with as little hesitation as if he was explaining some of the details of his great machine-shop in Philadelphia; "You see, according as the internal fire near the surface was extinguished or was withdrawn towards the centre, the lunar shell naturally cooled off. The logical consequences, of course, then gradually took place: extinction of organized beings; and then extinction of vegetation. The atmosphere, in the meantime, became thinner and thinner—partly drawn off with the water evaporated by the terrestrial attraction, and partly sinking with the solid water into the crust-cracks caused by cooling. With the disappearance of air capable of respiration, and of water capable of motion, the Moon, of course, became uninhabitable. From that day it became the abode of death, as completely as it is at the present moment."

"That is the fate in store for our Earth?"

"In all probability."

"And when is it to befall us?"

"Just as soon as the crust becomes cold enough to be uninhabitable."

"Perhaps your philosophership has taken the trouble to calculate how many years it will take our unfortunate Terra Mater to cool off?"

"Well; I have."

"And you can rely on your figures?"

"Implicitly."

"Why not tell it at once then to a fellow that's dying of impatience to know all about it? Captain, the Chair considers you one of the most tantalizing creatures in existence!"

"If you only listen, you will hear," replied M'Nicholl quietly. "By careful observations, extended through a series of many years, men have been able to discover the average loss of temperature endured by the Earth in a century. Taking this as the ground work of their calculations, they have ascertained that our Earth shall become an uninhabitable planet in about—"

"Don't cut her life too short! Be merciful!" cried Ardan in a pleading tone half in earnest. "Come, a good long day, your Honor! A good long day!"

"The planet that we call the Earth," continued the Captain, as grave as a judge, "will become uninhabitable to human beings, after a lapse of 400 thousand years from the present time."

"Hurrah!" cried Ardan, much relieved. "Vive la Science! Henceforward, what miscreant will persist in saying that the Savants are good for nothing? Proudly pointing to this calculation, can't they exclaim to all defamers: 'Silence, croakers! Our services are invaluable! Haven't we insured the Earth for 400 thousand years?' Again I say vive la Science!"

"Ardan," began the Captain with some asperity, "the foundations on which Science has raised—"

"I'm half converted already," interrupted Ardan in a cheery tone; "I do really believe that Science is not altogether unmitigated homebogue! Vive—"

—"But what has all this to do with the question under discussion?" interrupted Barbican, desirous to keep his friends from losing their tempers in idle disputation.

"True!" said Ardan. "The Chair, thankful for being called to order, would respectfully remind the house that the question before it is: Has the Moon been inhabited? Affirmative has been heard. Negative is called on to reply. Mr. Barbican has the parole."

But Mr. Barbican was unwilling just then to enter too deeply into such an exceedingly difficult subject. "The probabilities," he contented himself with saying, "would appear to be in favor of the Captain's speculations. But we must never forget that they are speculations—nothing more. Not the slightest evidence has yet been produced that the Moon is anything else than 'a dead and useless waste of extinct volcanoes.' No signs of cities, no signs of buildings, not even of ruins, none of anything that could be reasonably ascribed to the labors of intelligent creatures. No sign of change of any kind has been established. As for the agreement between the Moon's rotation and her revolution, which compels her to keep the same face constantly turned towards the Earth, we don't know that it has not existed from the beginning. As for what is called the effect of volcanic agency upon her surface, we don't know that her peculiar blistered appearance may not have been brought about altogether by the bubbling and spitting that blisters molten iron when cooling and contracting. Some close observers have even ventured to account for her craters by saying they were due to pelting showers of meteoric rain. Then again as to her atmosphere—why should she have lost her atmosphere? Why should it sink into craters? Atmosphere is gas, great in volume, small in matter; where would there be room for it? Solidified by the intense cold? Possibly in the night time. But would not the heat of the long day be great enough to thaw it back again? The same trouble attends the alleged disappearance of the water. Swallowed up in the cavernous cracks, it is said. But why are there cracks? Cooling is not always attended by cracking. Water cools without cracking; cannon balls cool without cracking. Too much stress has been laid on the great difference between the nucleus and the crust: it is really impossible to say where one ends and the other begins. In fact, no theory explains satisfactorily anything regarding the present state of the Moon's surface. In fact, from the day that Galileo compared her clustering craters to 'eyes on a peacock's tail' to the present time, we must acknowledge that we know nothing more than we can actually see, not one particle more of the Moon's history than our telescopes reveal to our corporal eyes!"

"In the lucid opinion of the honorable and learned gentleman who spoke last," said Ardan, "the Chair is compelled to concur. Therefore, as to the second question before the house for deliberation, Has the Moon been ever inhabited? the Chair gets out of its difficulty, as a Scotch jury does when it has not evidence enough either way, by returning a solemn verdict of Not Proven!"

"And with this conclusion," said Barbican, hastily rising, "of a subject on which, to tell the truth, we are unable as yet to throw any light worth speaking of, let us be satisfied for the present. Another question of greater moment to us just now is: where are we? It seems to me that we are increasing our distance from the Moon very decidedly and very rapidly."

It was easy to see that he was quite right in this observation. The Projectile, still following a northerly course and therefore approaching the lunar equator, was certainly getting farther and farther from the Moon. Even at 30° S., only ten degrees farther north than the latitude of Tycho, the travellers had considerable difficulty, comparatively, in observing the details of Pitatus, a walled mountain on the south shores of the Mare Nubium. In the "sea" itself, over which they now floated, they could see very little, but far to the left, on the 20th parallel, they could discern the vast crater of Bullialdus, 9,000 feet deep. On the right, they had just caught a glimpse of Purbach, a depressed valley almost square in shape with a round crater in the centre, when Ardan suddenly cried out:

"A Railroad!"

And, sure enough, right under them, a little northeast of Purbach, the travellers easily distinguished a long line straight and black, really not unlike a railroad cutting through a low hilly country.

This, Barbican explained, was of course no railway, but a steep cliff, at least 1,000 feet high, casting a very deep shadow, and probably the result of the caving in of the surface on the eastern edge.

Then they saw the immense crater of Arzachel and in its midst a cone mountain shining with dazzling splendor. A little north of this, they could detect the outlines of another crater, Alphonse, at least 70 miles in diameter. Close to it they could easily distinguish the immense crater or, as some observers call it, Ramparted Plain, Ptolemy, so well known to lunar astronomers, occupying, as it does, such a favorable position near the centre of the Moon, and having a diameter fully, in one direction at least, 120 miles long.

The travellers were now in about the same latitude as that at which they had at first approached the Moon, and it was here that they began most unquestionably to leave her. They looked and looked, readjusting their glasses, but the details were becoming more and more difficult to catch. The reliefs grew more and more blurred and the outlines dimmer and dimmer. Even the great mountain profiles began to fade away, the dazzling colors to grow duller, the jet black shadows greyer, and the general effect mistier.

At last, the distance had become so great that, of this lunar world so wonderful, so fantastic, so weird, so mysterious, our travellers by degrees lost even the consciousness, and their sensations, lately so vivid, grew fainter and fainter, until finally they resembled those of a man who is suddenly awakened from a peculiarly strange and impressive dream.

CHAPTER XIX. IN EVERY FIGHT, THE IMPOSSIBLE WINS.

No matter what we have been accustomed to, it is sad to bid it farewell forever. The glimpse of the Moon's wondrous world imparted to Barbican and his companions had been, like that of the Promised Land to Moses on Mount Pisgah, only a distant and a dark one, yet it was with inexpressibly mournful eyes that, silent and thoughtful, they now watched her fading away slowly from their view, the conviction impressing itself deeper and deeper in their souls that, slight as their acquaintance had been, it was never to be renewed again. All doubt
