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

Indeed this was all they saw of the globe lost in the shadow, an inferior orb of the solar world, rising and setting to the great planets like a simple morning or evening star! This globe, where they had left all their affections, was nothing more than a fugitive crescent!

Long did the three friends look without speaking, though united in heart, whilst the projectile sped onward with an ever-decreasing speed. Then an irresistible drowsiness crept over their brain. Was it weariness both of body and mind? No doubt; for after the over-excitement of those last hours passed upon earth, reaction was inevitable.

"Well," said Nicholl, "since we must sleep, let us sleep."

And stretching themselves on their couches, they were all three soon in a profound slumber.

But they had not forgotten themselves more than a quarter of an hour, when Barbicane sat up suddenly, and rousing his companions with a loud voice, exclaimed, —

"I have found it!"

"What have you found?" asked Michel Ardan, jumping from his bed.

"The reason why we did not hear the detonation of the Columbiad."

"And it is – ?" said Nicholl.

"Because our projectile travelled faster than the sound!"

CHAPTER III.
THEIR PLACE OF SHELTER

This curious but certainly correct explanation once given, the three friends returned to their slumbers. Could they have found a calmer or more peaceful spot to sleep in? On the earth, houses, towns, cottages, and country feel every shock given to the exterior of the globe. On sea, the vessels rocked by the waves are still in motion; in the air, the balloon oscillates incessantly on the fluid strata of divers densities. This projectile alone, floating in perfect space, in the midst of perfect silence, offered perfect repose.

Thus the sleep of our adventurous travellers might have been indefinitely prolonged, if an unexpected noise had not awakened them at about seven o'clock in the morning of the 2nd of December, eight hours after their departure.

This noise was a very natural barking.

"The dogs! it is the dogs!" exclaimed Michel Ardan, rising at once.

"They are hungry," said Nicholl.

"By Jove!" replied Michel, "we have forgotten them."

"Where are they?" asked Barbicane.

They looked and found one of the animals crouched under the divan. Terrified and shaken by the initiatory shock, it had remained in the corner till its voice returned with the pangs of hunger. It was the amiable Diana, still very confused, who crept out of her retreat, though not without much persuasion, Michel Ardan encouraging her with most gracious words.

"Come, Diana," said he; "come, my girl! thou whose destiny will be marked in the cynegetic annals; thou whom the pagans would have given as companion to the god Anubis, and Christians as friend to St. Roch; thou who art rushing into interplanetary space, and wilt perhaps be the Eve of all Selenite dogs! come, Diana, come here."

Diana, flattered or not, advanced by degrees, uttering plaintive cries.

"Good," said Barbicane; "I see Eve, but where is Adam?"

"Adam?" replied Michel; "Adam cannot be far off; he is there somewhere; we must call him. Satellite! here, Satellite!"

But Satellite did not appear. Diana would not leave off howling. They found, however, that she was not bruised, and they gave her a pie, which silenced her complaints. As to Satellite, he seemed quite lost. They had to hunt a long time before finding him in one of the upper compartments of the projectile, whither some unaccountable shock must have violently hurled him. The poor beast, much hurt, was in a piteous state.

"The devil!" said Michel.

They brought the unfortunate dog down with great care. Its skull had been broken against the roof, and it seemed unlikely that he could recover from such a shock. Meanwhile, he was stretched comfortably on a cushion. Once there, he heaved a sigh.

"We will take care of you," said Michel; "we are responsible for your existence. I would rather lose an arm than a paw of my poor Satellite."

Saying which, he offered some water to the wounded dog, who swallowed it with avidity.

This attention paid, the travellers watched the earth and the moon attentively. The earth was now only discernible by a cloudy disc ending in a crescent, rather more contracted than that of the previous evening; but its expanse was still enormous, compared with that of the moon, which was approaching nearer and nearer to a perfect circle.

"By Jove!" said Michel Ardan, "I am really sorry that we did not start when the earth was full, that is to say, when our globe was in opposition to the sun."

"Why?" asked Nicholl.

"Because we should have seen our continents and seas in a new light, – the first resplendent under the solar rays, the latter cloudy as represented on some maps of the world. I should like to have seen those poles of the earth on which the eye of man has never yet rested.

"I dare say," replied Barbicane; "but if the earth had been full, the moon would have been new; that is to say, invisible, because of the rays of the sun. It is better for us to see the destination we wish to reach, than the point of departure."

"You are right, Barbicane," replied Captain Nicholl; "and, besides, when we have reached the moon, we shall have time during the long lunar nights to consider at our leisure the globe on which our likenesses swarm."

"Our likenesses!" exclaimed Michel Ardan; "they are no more our likenesses than the Selenites are! We inhabit a new world, peopled by ourselves – the projectile! I am Barbicane's likeness, and Barbicane is Nicholl's. Beyond us, around us, human nature is at an end, and we are the only population of this microcosm until we become pure Selenites."

"In about eighty-eight hours," replied the captain.

"Which means to say?" asked Michel Ardan.

"That it is half-past eight," replied Nicholl.

"Very well," retorted Michel; "then it is impossible for me to find even the shadow of a reason why we should not go to breakfast."

Indeed the inhabitants of the new star could not live without eating, and their stomachs were suffering from the imperious laws of hunger. Michel Ardan, as a Frenchman, was declared chief cook, an important function, which raised no rival. The gas gave sufficient heat for the culinary apparatus, and the provision-box furnished the elements of this first feast.

The breakfast began with three bowls of excellent soup, thanks to the liquefaction in hot water of those precious cakes of Liebig, prepared from the best parts of the ruminants of the Pampas. To the soup succeeded some beefsteaks, compressed by an hydraulic press, as tender and succulent as if brought straight from the kitchen of an English eating-house. Michel, who was imaginative, maintained that they were even "red."

Preserved vegetables ("fresher than nature," said the amiable Michel) succeeded the dish of meat; and was followed by some cups of tea with bread and butter, after the American fashion.

The beverage was declared exquisite, and was due to the infusion of the choicest leaves, of which the Emperor of Russia had given some chests for the benefit of the travellers.

And lastly, to crown the repast, Ardan brought out a fine bottle of Nuits, which was found "by chance" in the provision-box. The three friends drank to the union of the earth and her satellite.

And, as if he had not already done enough for the generous wine which he had distilled on the slopes of Burgundy, the sun chose to be of the party. At this moment the projectile emerged from the conical shadow cast by the terrestrial globe, and the rays of the radiant orb struck the lower disc of the projectile direct occasioned by the angle which the moon's orbit makes with that of the earth.

"The sun!" exclaimed Michel Ardan.

"No doubt," replied Barbicane; "I expected it."

"But," said Michel, "the conical shadow which the earth leaves in space extends beyond the moon?"

"Far beyond it, if the atmospheric refraction is not taken into consideration," said Barbicane. "But when the moon is enveloped in this shadow, it is because the centres of the three stars, the sun, the earth, and the moon, are all in one and the same straight line. Then the nodes coincide with the phases of the moon, and there is an eclipse. If we had started when there was an eclipse of the moon, all our passage would have been in the shadow, which would have been a pity."

"Why?"

"Because, though we are floating in space, our projectile, bathed in the solar rays, will receive their light and heat. It economizes the gas, which is in every respect a good economy."

Indeed, under these rays which no atmosphere can temper, either in temperature or brilliancy, the projectile grew warm and bright, as if it had passed suddenly from winter to summer. The moon above, the sun beneath, were inundating it with their fire.

"It is pleasant here," said Nicholl.

"I should think so," said Michel Ardan. "With a little earth spread on our aluminium planet we should have green peas in twenty-four hours. I have but one fear, which is that the walls of the projectile might melt."

"Calm yourself, my worthy friend," replied Barbicane; "the projectile withstood a very much higher temperature than this as it slid through the strata of the atmosphere. I should not be surprised if it did not look like a meteor on fire to the eyes of the spectators in Florida."

"But then Joseph T. Maston will think we are roasted!"

"What astonishes me," said Barbicane, "is that we have not been. That was a danger we had not provided for."

"I feared it," said Nicholl simply.

"And you never mentioned it, my sublime captain," exclaimed Michel Ardan, clasping his friend's hand.

Barbicane now began to settle himself in the projectile as if he was never to leave it. One must remember that this aerial car had a base with a superficies of fifty-four square feet. Its height to the roof was twelve feet. Carefully laid out in the inside, and little encumbered by instruments and travelling utensils which each had their particular place, it left the three travellers a certain freedom of movement. The thick window inserted in the bottom could bear any amount of weight, and Barbicane and his companions walked upon it as if it were solid plank; but the sun striking it directly with its rays lit the interior of the projectile from beneath, thus producing singular effects of light.

They began by investigating the state of their store of water and provisions, neither of which had suffered, thanks to the care taken to deaden the shock. Their provisions were abundant, and plentiful enough to last the three travellers for more than a year. Barbicane wished to be cautious, in case the projectile should land on a part of the moon which was utterly barren. As to water and the reserve of brandy, which consisted of fifty gallons, there was only enough for two months; but according to the last observations of astronomers, the moon had a low, dense, and thick atmosphere, at least in the deep valleys, and there springs and streams could not fail. Thus, during their passage, and for the first year of their settlement on the lunar continent, these adventurous explorers would suffer neither hunger nor thirst.

Now about the air in the projectile. There, too, they were secure. Reiset and Regnaut's apparatus, intended for the production of oxygen, was supplied with chlorate of potassium for two months. They necessarily consumed a certain quantity of gas, for they were obliged to keep the producing substance at a temperature of above 400°. But there again they were all safe. The apparatus only wanted a little care. But it was not enough to renew the oxygen; they must absorb the carbonic acid produced by expiration. During the last twelve hours the atmosphere of the projectile had become charged with this deleterious gas. Nicholl discovered the state of the air by observing Diana panting painfully. The carbonic acid, by a phenomenon similar to that produced in the famous Grotto del Cane, had collected at the bottom of the projectile owing to its weight. Poor Diana, with her head low, would suffer before her masters from the presence of this gas. But Captain Nicholl hastened to remedy this state of things, by placing on the floor several receivers containing caustic potash which he shook about for a time, and this substance, greedy of carbonic acid, soon completely absorbed it, thus purifying the air.

An inventory of instruments was then begun. The thermometers and barometers had resisted, all but one minimum thermometer, the glass of which was broken. An excellent aneroid was drawn from the wadded box which contained it and hung on the wall. Of course it was only affected by and marked the pressure of the air inside the projectile, but it also showed the quantity of moisture which it contained. At that moment its needle oscillated between 25.24 and 25.08.

It was fine weather.

Barbicane had also brought several compasses, which he found intact. One must understand that under present conditions their needles were acting wildly, that is without any constant direction. Indeed, at the distance they were from the earth, the magnetic pole could have no perceptible action upon the apparatus; but the box placed on the lunar disc might perhaps exhibit some strange phenomena. In any case it would be interesting to see whether the earth's satellite submitted like herself to its magnetic influence.

A hypsometer to measure the height of the lunar mountains, a sextant to take the height of the sun, glasses which would be useful as they neared the moon, all these instruments were carefully looked over, and pronounced good in spite of the violent shock.

As to the pickaxes and different tools which were Nicholl's especial choice; as to the sacks of different kinds of grain and shrubs which Michel Ardan hoped to transplant into Selenite ground, they were stowed away in the upper part of the projectile. There was a sort of granary there, loaded with things which the extravagant Frenchman had heaped up. What they were no one knew, and the good-tempered fellow did not explain. Now and then he climbed up by cramp-irons riveted to the walls, but kept the inspection to himself. He arranged and rearranged, he plunged his hand rapidly into certain mysterious boxes, singing in one of the falsest of voices an old French refrain to enliven the situation.

Barbicane observed with some interest that his guns and other arms had not been damaged. These were important, because, heavily loaded, they were to help to lessen the fall of the projectile, when drawn by the lunar attraction (after having passed the point of neutral attraction) on to the moon's surface; a fall which ought to be six times less rapid than it would have been on the earth's surface, thanks to the difference of bulk. The inspection ended with general satisfaction, when each returned to watch space through the side windows and the lower glass coverlid.

There was the same view. The whole extent of the celestial sphere swarmed with stars and constellations of wonderful purity, enough to drive an astronomer out of his mind! On one side the sun, like the mouth of a lighted oven, a dazzling disc without a halo, standing out on the dark background of the sky! On the other, the moon returning its fire by reflection, and apparently motionless in the midst of the starry world. Then, a large spot seemingly nailed to the firmament, bordered by a silvery cord: it was the earth! Here and there nebulous masses like large flakes of starry snow; and from the zenith to the nadir, an immense ring formed by an impalpable dust of stars, the "Milky Way," in the midst of which the sun ranks only as a star of the fourth magnitude. The observers could not take their eyes from this novel spectacle, of which no description could give an adequate idea. What reflections it suggested! What emotions hitherto unknown awoke in their souls! Barbicane wished to begin the relation of his journey while under its first impressions, and hour after hour took notes of all facts happening in the beginning of the enterprise. He wrote quietly, with his large square writing, in a businesslike style.

During this time Nicholl, the calculator, looked over the minutes of their passage, and worked out figures with unparalleled dexterity. Michel Ardan chatted first with Barbicane, who did not answer him, and then with Nicholl, who did not hear him, with Diana, who understood none of his theories, and lastly with himself, questioning and answering, going and coming, busy with a thousand details; at one time bent over the lower glass, at another roosting in the heights of the projectile, and always singing. In this microcosm he represented French loquacity and excitability, and we beg you to believe that they were well represented. The day, or rather (for the expression is not correct) the lapse of twelve hours, which forms a day upon earth, closed with a plentiful supper carefully prepared. No accident of any nature had yet happened to shake the travellers' confidence; so, full of hope, already sure of success, they slept peacefully, whilst the projectile under an uniformly decreasing speed was crossing the sky.

CHAPTER IV.
A LITTLE ALGEBRA

The night passed without incident. The word "night," however, is scarcely applicable.

The position of the projectile with regard to the sun did not change. Astronomically, it was daylight on the lower part, and night on the upper; so when during this narrative these words are used, they represent the lapse of time between the rising and setting of the sun upon the earth.

The travellers' sleep was rendered more peaceful by the projectile's excessive speed, for it seemed absolutely motionless. Not a motion betrayed its onward course through space. The rate of progress, however rapid it might be, cannot produce any sensible effect on the human frame when it takes place in a vacuum, or when the mass of air circulates with the body which is carried with it. What inhabitant of the earth perceives its speed, which, however, is at the rate of 68,000 miles per hour? Motion under such conditions is "felt" no more than repose; and when a body is in repose it will remain so as long as no strange force displaces it; if moving, it will not stop unless an obstacle comes in its way. This indifference to motion or repose is called inertia.

Barbicane and his companions might have believed themselves perfectly stationary, being shut up in the projectile; indeed, the effect would have been the same if they had been on the outside of it. Had it not been for the moon, which was increasing above them, they might have sworn that they were floating in complete stagnation.

That morning, the 3rd of December, the travellers were awakened by a joyous but unexpected noise; it was the crowing of a cock which sounded through the car. Michel Ardan, who was the first on his feet, climbed to the top of the projectile, and shutting a box, the lid of which was partly open, said in a low voice, "Will you hold your tongue? That creature will spoil my design!"

But Nicholl and Barbicane were awake.

"A cock!" said Nicholl.

"Why no, my friends," Michel answered quickly; "it was I who wished to awake you by this rural sound." So saying, he gave vent to a splendid cock-a-doodledoo, which would have done honour to the proudest of poultry-yards.

The two Americans could not help laughing.

"Fine talent that," said Nicholl, looking suspiciously at his companion.

"Yes," said Michel; "a joke in my country. It is very Gallic; they play the cock so in the best society."

Then turning the conversation, —

"Barbicane, do you know what I have been thinking of all night?"

"No," answered the president.

"Of our Cambridge friends. You have already remarked that I am an ignoramus in mathematical subjects; and it is impossible for me to find out how the savants of the Observatory were able to calculate what initiatory speed the projectile ought to have on leaving the Columbiad in order to attain the moon."

"You mean to say," replied Barbicane, "to attain that neutral point where the terrestrial and lunar attractions are equal; for, starting from that point, situated about nine-tenths of the distance travelled over, the projectile would simply fall upon the moon, on account of its weight."

"So be it," said Michel; "but, once more; how could they calculate the initiatory speed?"

"Nothing can be easier," replied Barbicane.

"And you knew how to make that calculation?" asked Michel Ardan.

"Perfectly. Nicholl and I would have made it, if the Observatory had not saved us the trouble."

"Very well, old Barbicane," replied Michel; "they might have cut off my head, beginning at my feet, before they could have made me solve that problem."

"Because you do not know algebra," answered Barbicane quietly.

"Ah, there you are, you eaters of x¹; you think you have said all when you have said 'Algebra.'"

"Michel," said Barbicane, "can you use a forge without a hammer, or plough without a ploughshare?"

"Hardly."

"Well, algebra is a tool, like the plough or the hammer, and a good tool to those who know how to use it."

"Seriously?"

"Quite seriously."

"And can you use that tool in my presence?"

"If it will interest you."

"And show me how they calculated the initiatory speed of our car?"

"Yes, my worthy friend; taking into consideration all the elements of the problem, the distance from the centre of the earth to the centre of the moon, of the radius of the earth, of its bulk, and of the bulk of the moon, I can tell exactly what ought to be the initiatory speed of the projectile, and that by a simple formula."

"Let us see."

"You shall see it; only I shall not give you the real course drawn by the projectile between the moon and the earth in considering their motion round the sun. No, I shall consider these two orbs as perfectly motionless, which will answer all our purpose."

"And why?"

"Because it will be trying to solve the problem called 'the problem of the three bodies,' for which the integral calculus is not yet far enough advanced."

"Then," said Michel Ardan, in his sly tone, "mathematics have not said their last word?"

"Certainly not," replied Barbicane.

"Well, perhaps the Selenites have carried the integral calculus farther than you have; and, by the bye, what is 'integral calculus?'"

"It is a calculation the converse of the differential," replied Barbicane seriously.

"Much obliged; it is all very clear, no doubt."

"And now," continued Barbicane, "a slip of paper and a bit of pencil, and before a half-hour is over I will have found the required formula."

Half an hour had not elapsed before Barbicane, raising his head, showed Michel Ardan a page covered with algebraical signs, in which the general formula for the solution was contained.

"Well, and does Nicholl understand what that means?"

"Of course, Michel," replied the captain. "All these signs, which seem cabalistic to you, form the plainest, the clearest, and the most logical language to those who know how to read it."

"And you pretend, Nicholl," asked Michel, "that by means of these hieroglyphics, more incomprehensible than the Egyptian Ibis, you can find what initiatory speed it was necessary to give to the projectile?"

"Incontestably," replied Nicholl; "and even by this same formula I can always tell you its speed at any point of its transit."

"On your word?"

"On my word."

"Then you are as cunning as our president."

"No, Michel; the difficult part is what Barbicane has done; that is, to get an equation which shall satisfy all the conditions of the problem. The remainder is only a question of arithmetic, requiring merely the knowledge of the four rules."

"That is something!" replied Michel Ardan, who for his life could not do addition right, and who defined the rule as a Chinese puzzle, which allowed one to obtain all sorts of totals.

"The expression v zero, which you see in that equation, is the speed which the projectile will have on leaving the atmosphere."

"Just so," said Nicholl; "it is from that point that we must calculate the velocity, since we know already that the velocity at departure was exactly one and a half times more than on leaving the atmosphere."

"I understand no more," said Michel.

"It is a very simple calculation," said Barbicane.

"Not as simple as I am," retorted Michel.

"That means, that when our projectile reached the limits of the terrestrial atmosphere it had already lost one-third of its initiatory speed."

"As much as that?"

"Yes, my friend; merely by friction against the atmospheric strata. You understand that the faster it goes the more resistance it meets with from the air."

"That I admit," answered Michel; "and I understand it, although your x's and zero's, and algebraic formulæ, are rattling in my head like nails in a bag."

"First effects of algebra," replied Barbicane; "and now, to finish, we are going to prove the given number of these different expressions, that is, work out their value."

"Finish me!" replied Michel.

Barbicane took the paper, and began again to make his calculations with great rapidity. Nicholl looked over and greedily read the work as it proceeded.

"That's it! that's it!" at last he cried.

"Is it clear?" asked Barbicane.

"It is written in letters of fire," said Nicholl.

"Wonderful fellows!" muttered Ardan.

"Do you understand it at last?" asked Barbicane.

"Do I understand it?" cried Ardan; "my head is splitting with it."

"And now," said Nicholl, "to find out the speed of the projectile when it left the atmosphere, we have only to calculate that."

The captain, as a practical man equal to all difficulties, began to write with frightful rapidity. Divisions and multiplications grew under his fingers; the figures were like hail on the white page. Barbicane watched him, whilst Michel Ardan nursed a growing headache with both hands.

"Very well?" asked Barbicane, after some minutes' silence.

"Well!" replied Nicholl; "every calculation made, v zero, that is to say, the speed necessary for the projectile on leaving the atmosphere, to enable it to reach the equal point of attraction, ought to be – "

"Yes?" said Barbicane.

"Twelve thousand yards."

"What!" exclaimed Barbicane, starting; "you say – "

"Twelve thousand yards."

"The devil!" cried the president, making a gesture of despair.

"What is the matter?" asked Michel Ardan, much surprised.

"What is the matter! why, if at this moment our speed had already diminished one-third by friction, the initiatory speed ought to have been – "

"Seventeen thousand yards."

"And the Cambridge Observatory declared that 12,000 yards was enough at starting; and our projectile, which only started with that speed – "

"Well?" asked Nicholl.

"Well, it will not be enough."

"Good."

"We shall not be able to reach the neutral point."

"The deuce!"

"We shall not even get half way."

"In the name of the projectile!" exclaimed Michel Ardan, jumping as if it was already on the point of striking the terrestrial globe.

"And we shall fall back upon the earth!"
