From the Earth to the Moon, Ch 18: THE PASSENGER OF THE ATLANTA

CHAPTER XVIII -- THE PASSENGER OF THE ATLANTA
If this astounding news, instead of flying through the electric wires, had simply arrived by post in the ordinary sealed envelope, Barbicane would not have hesitated a moment. He would have held his tongue about it, both as a measure of prudence, and in order not to have to reconsider his plans. This telegram might be a cover for some jest, especially as it came from a Frenchman. What human being would ever have conceived the idea of such a journey? and, if such a person really existed, he must be an idiot, whom one would shut up in a lunatic ward, rather than within the walls of the projectile.

The contents of the dispatch, however, speedily became known; for the telegraphic officials possessed but little discretion, and Michel Ardan's proposition ran at once throughout the several States of the Union. Barbicane, had, therefore, no further motives for keeping silence. Consequently, he called together such of his colleagues as were at the moment in Tampa Town, and without any expression of his own opinions simply read to them the laconic text itself. It was received with every possible variety of expressions of doubt, incredulity, and derision from every one, with the exception of J. T. Maston, who exclaimed, "It is a grand idea, however!"

When Barbicane originally proposed to send a shot to the moon every one looked upon the enterprise as simple and practicable enough— a mere question of gunnery; but when a person, professing to be a reasonable being, offered to take passage within the projectile, the whole thing became a farce, or, in plainer language a humbug.

One question, however, remained. Did such a being exist? This telegram flashed across the depths of the Atlantic, the designation of the vessel on board which he was to take his passage, the date assigned for his speedy arrival, all combined to impart a certain character of reality to the proposal. They must get some clearer notion of the matter. Scattered groups of inquirers at length condensed themselves into a compact crowd, which made straight for the residence of President Barbicane. That worthy individual was keeping quiet with the intention of watching events as they arose. But he had forgotten to take into account the public impatience; and it was with no pleasant countenance that he watched the population of Tampa Town gathering under his windows. The murmurs and vociferations below presently obliged him to appear. He came forward, therefore, and on silence being procured, a citizen put point-blank to him the following question: "Is the person mentioned in the telegram, under the name of Michel Ardan, on his way here? Yes or no."

"Gentlemen," replied Barbicane, "I know no more than you do."

"We must know," roared the impatient voices.

"Time will show," calmly replied the president.

"Time has no business to keep a whole country in suspense," replied the orator. "Have you altered the plans of the projectile according to the request of the telegram?"

"Not yet, gentlemen; but you are right! we must have better information to go by. The telegraph must complete its information."

"To the telegraph!" roared the crowd.

Barbicane descended; and heading the immense assemblage, led the way to the telegraph office. A few minutes later a telegram was dispatched to the secretary of the underwriters at Liverpool, requesting answers to the following queries:

"About the ship Atlanta— when did she leave Europe? Had she on board a Frenchman named Michel Ardan?"

Two hours afterward Barbicane received information too exact to leave room for the smallest remaining doubt.

"The steamer Atlanta from Liverpool put to sea on the 2nd of October, bound for Tampa Town, having on board a Frenchman borne on the list of passengers by the name of Michel Ardan."

That very evening he wrote to the house of Breadwill and Co., requesting them to suspend the casting of the projectile until the receipt of further orders. On the 10th of October, at nine A.M., the semaphores of the Bahama Canal signaled a thick smoke on the horizon. Two hours later a large steamer exchanged signals with them. the name of the Atlanta flew at once over Tampa Town. At four o'clock the English vessel entered the Bay of Espiritu Santo. At five it crossed the passage of Hillisborough Bay at full steam. At six she cast anchor at Port Tampa. The anchor had scarcely caught the sandy bottom when five hundred boats surrounded the Atlanta, and the steamer was taken by assault. Barbicane was the first to set foot on deck, and in a voice of which he vainly tried to conceal the emotion, called "Michel Ardan."

"Here!" replied an individual perched on the poop.

Barbicane, with arms crossed, looked fixedly at the passenger of the Atlanta.

He was a man of about forty-two years of age, of large build, but slightly round-shouldered. His massive head momentarily shook a shock of reddish hair, which resembled a lion's mane. His face was short with a broad forehead, and furnished with a moustache as bristly as a cat's, and little patches of yellowish whiskers upon full cheeks. Round, wildish eyes, slightly near-sighted, completed a physiognomy essentially feline. His nose was firmly shaped, his mouth particularly sweet in expression, high forehead, intelligent and furrowed with wrinkles like a newly-plowed field. The body was powerfully developed and firmly fixed upon long legs. Muscular arms, and a general air of decision gave him the appearance of a hardy, jolly, companion. He was dressed in a suit of ample dimensions, loose neckerchief, open shirtcollar, disclosing a robust neck; his cuffs were invariably unbuttoned, through which appeared a pair of red hands.

On the bridge of the steamer, in the midst of the crowd, he bustled to and fro, never still for a moment, "dragging his anchors," as the sailors say, gesticulating, making free with everybody, biting his nails with nervous avidity. He was one of those originals which nature sometimes invents in the freak of a moment, and of which she then breaks the mould.

Among other peculiarities, this curiosity gave himself out for a sublime ignoramus, "like Shakespeare," and professed supreme contempt for all scientific men. Those "fellows," as he called them, "are only fit to mark the points, while we play the game." He was, in fact, a thorough Bohemian, adventurous, but not an adventurer; a hare-brained fellow, a kind of Icarus, only possessing relays of wings. For the rest, he was ever in scrapes, ending invariably by falling on his feet, like those little figures which they sell for children's toys. In a few words, his motto was "I have my opinions," and the love of the impossible constituted his ruling passion.

Such was the passenger of the Atlanta, always excitable, as if boiling under the action of some internal fire by the character of his physical organization. If ever two individuals offered a striking contrast to each other, these were certainly Michel Ardan and the Yankee Barbicane; both, moreover, being equally enterprising and daring, each in his own way.

The scrutiny which the president of the Gun Club had instituted regarding this new rival was quickly interrupted by the shouts and hurrahs of the crowd. The cries became at last so uproarious, and the popular enthusiasm assumed so personal a form, that Michel Ardan, after having shaken hands some thousands of times, at the imminent risk of leaving his fingers behind him, was fain at last to make a bolt for his cabin.

Barbicane followed him without uttering a word.

"You are Barbicane, I suppose?" said Michel Ardan, in a tone of voice in which he would have addressed a friend of twenty years' standing.

"Yes," replied the president of the Gun Club.

"All right! how d'ye do, Barbicane? how are you getting on— pretty well? that's right."

"So," said Barbicane without further preliminary, "you are quite determined to go."

"Quite decided."

"Nothing will stop you?"

"Nothing. Have you modified your projectile according to my telegram."

"I waited for your arrival. But," asked Barbicane again, "have you carefully reflected?"

"Reflected? have I any time to spare? I find an opportunity of making a tour in the moon, and I mean to profit by it. There is the whole gist of the matter."

Barbicane looked hard at this man who spoke so lightly of his project with such complete absence of anxiety. "But, at least," said he, "you have some plans, some means of carrying your project into execution?"

"Excellent, my dear Barbicane; only permit me to offer one remark: My wish is to tell my story once for all, to everybody, and then have done with it; then there will be no need for recapitulation. So, if you have no objection, assemble your friends, colleagues, the whole town, all Florida, all America if you like, and to-morrow I shall be ready to explain my plans and answer any objections whatever that may be advanced. You may rest assured I shall wait without stirring. Will that suit you?"

"All right," replied Barbicane.

So saying, the president left the cabin and informed the crowd of the proposal of Michel Ardan. His words were received with clappings of hands and shouts of joy. They had removed all difficulties. To-morrow every one would contemplate at his ease this European hero. However, some of the spectators, more infatuated than the rest, would not leave the deck of the Atlanta. They passed the night on board. Among others J. T. Maston got his hook fixed in the combing of the poop, and it pretty nearly required the capstan to get it out again.

"He is a hero! a hero!" he cried, a theme of which he was never tired of ringing the changes; "and we are only like weak, silly women, compared with this European!"

As to the president, after having suggested to the visitors it was time to retire, he re-entered the passenger's cabin, and remained there till the bell of the steamer made it midnight.

But then the two rivals in popularity shook hands heartily and parted on terms of intimate friendship.

From the Earth to the Moon, Ch 17: A TELEGRAPHIC DISPATCH

CHAPTER XVII --A TELEGRAPHIC DISPATCH
The great works undertaken by the Gun Club had now virtually come to an end; and two months still remained before the day for the discharge of the shot to the moon. To the general impatience these two months appeared as long as years! Hitherto the smallest details of the operation had been daily chronicled by the journals, which the public devoured with eager eyes.

Just at this moment a circumstance, the most unexpected, the most extraordinary and incredible, occurred to rouse afresh their panting spirits, and to throw every mind into a state of the most violent excitement.

One day, the 30th of September, at 3:47 P.M., a telegram, transmitted by cable from Valentia (Ireland) to Newfoundland and the American Mainland, arrived at the address of President Barbicane.

The president tore open the envelope, read the dispatch, and, despite his remarkable powers of self-control, his lips turned pale and his eyes grew dim, on reading the twenty words of this telegram.

Here is the text of the dispatch, which figures now in the archives of the Gun Club:

FRANCE, PARIS,
30 September, 4 A.M.
Barbicane, Tampa Town, Florida, United States.

Substitute for your spherical shell a cylindro-conical projectile.
I shall go inside. Shall arrive by steamer Atlanta.
MICHEL ARDAN.

From the Earth to the Moon, Ch 16: THE COLUMBIAD

CHAPTER XVI -- THE COLUMBIAD
Had the casting succeeded? They were reduced to mere conjecture. There was indeed every reason to expect success, since the mould has absorbed the entire mass of the molten metal; still some considerable time must elapse before they could arrive at any certainty upon the matter.

The patience of the members of the Gun Club was sorely tried during this period of time. But they could do nothing. J. T. Maston escaped roasting by a miracle. Fifteen days after the casting an immense column of smoke was still rising in the open sky and the ground burned the soles of the feet within a radius of two hundred feet round the summit of Stones Hill. It was impossible to approach nearer. All they could do was to wait with what patience they might.

"Here we are at the 10th of August," exclaimed J. T. Maston one morning, "only four months to the 1st of December! We shall never be ready in time!" Barbicane said nothing, but his silence covered serious irritation.

However, daily observations revealed a certain change going on in the state of the ground. About the 15th of August the vapors ejected had sensibly diminished in intensity and thickness. Some days afterward the earth exhaled only a slight puff of smoke, the last breath of the monster enclosed within its circle of stone. Little by little the belt of heat contracted, until on the 22nd of August, Barbicane, his colleagues, and the engineer were enabled to set foot on the iron sheet which lay level upon the summit of Stones Hill.

"At last!" exclaimed the president of the Gun Club, with an immense sigh of relief.

The work was resumed the same day. They proceeded at once to extract the interior mould, for the purpose of clearing out the boring of the piece. Pickaxes and boring irons were set to work without intermission. The clayey and sandy soils had acquired extreme hardness under the action of the heat; but, by the aid of the machines, the rubbish on being dug out was rapidly carted away on railway wagons; and such was the ardor of the work, so persuasive the arguments of Barbicane's dollars, that by the 3rd of September all traces of the mould had entirely disappeared.

Immediately the operation of boring was commenced; and by the aid of powerful machines, a few weeks later, the inner surface of the immense tube had been rendered perfectly cylindrical, and the bore of the piece had acquired a thorough polish.

At length, on the 22d of September, less than a twelvemonth after Barbicane's original proposition, the enormous weapon, accurately bored, and exactly vertically pointed, was ready for work. There was only the moon now to wait for; and they were pretty sure that she would not fail in the rendezvous.

The ecstasy of J. T. Maston knew no bounds, and he narrowly escaped a frightful fall while staring down the tube. But for the strong hand of Colonel Blomsberry, the worthy secretary, like a modern Erostratus, would have found his death in the depths of the Columbiad.

The cannon was then finished; there was no possible doubt as to its perfect completion. So, on the 6th of October, Captain Nicholl opened an account between himself and President Barbicane, in which he debited himself to the latter in the sum of two thousand dollars. One may believe that the captain's wrath was increased to its highest point, and must have made him seriously ill. However, he had still three bets of three, four, and five thousand dollars, respectively; and if he gained two out of these, his position would not be very bad. But the money question did not enter into his calculations; it was the success of his rival in casting a cannon against which iron plates sixty feet thick would have been ineffectual, that dealt him a terrible blow.

After the 23rd of September the enclosure of Stones hill was thrown open to the public; and it will be easily imagined what was the concourse of visitors to this spot! There was an incessant flow of people to and from Tampa Town and the place, which resembled a procession, or rather, in fact, a pilgrimage.

It was already clear to be seen that, on the day of the experiment itself, the aggregate of spectators would be counted by millions; for they were already arriving from all parts of the earth upon this narrow strip of promontory. Europe was emigrating to America.

Up to that time, however, it must be confessed, the curiosity of the numerous comers was but scantily gratified. Most had counted upon witnessing the spectacle of the casting, and they were treated to nothing but smoke. This was sorry food for hungry eyes; but Barbicane would admit no one to that operation. Then ensued grumbling, discontent, murmurs; they blamed the president, taxed him with dictatorial conduct. His proceedings were declared "un-American." There was very nearly a riot round Stones Hill; but Barbicane remained inflexible. When, however, the Columbiad was entirely finished, this state of closed doors could no longer be maintained; besides it would have been bad taste, and even imprudence, to affront the public feeling. Barbicane, therefore, opened the enclosure to all comers; but, true to his practical disposition, he determined to coin money out of the public curiosity.

It was something, indeed, to be enabled to contemplate this immense Columbiad; but to descend into its depths, this seemed to the Americans the ne plus ultra of earthly felicity. Consequently, there was not one curious spectator who was not willing to give himself the treat of visiting the interior of this great metallic abyss. Baskets suspended from steam-cranes permitted them to satisfy their curiosity. There was a perfect mania. Women, children, old men, all made it a point of duty to penetrate the mysteries of the colossal gun. The fare for the descent was fixed at five dollars per head; and despite this high charge, during the two months which preceded the experiment, the influx of visitors enabled the Gun Club to pocket nearly five hundred thousand dollars!

It is needless to say that the first visitors of the Columbiad were the members of the Gun Club. This privilege was justly reserved for that illustrious body. The ceremony took place on the 25th of September. A basket of honor took down the president, J. T. Maston, Major Elphinstone, General Morgan, Colonel Blomsberry, and other members of the club, to the number of ten in all. How hot it was at the bottom of that long tube of metal! They were half suffocated. But what delight! What ecstasy! A table had been laid with six covers on the massive stone which formed the bottom of the Columbiad, and lighted by a jet of electric light resembling that of day itself. Numerous exquisite dishes, which seemed to descend from heaven, were placed successively before the guests, and the richest wines of France flowed in profusion during this splendid repast, served nine hundred feet beneath the surface of the earth!

The festival was animated, not to say somewhat noisy. Toasts flew backward and forward. They drank to the earth and to her satellite, to the Gun Club, the Union, the Moon, Diana, Phoebe, Selene, the "peaceful courier of the night!" All the hurrahs, carried upward upon the sonorous waves of the immense acoustic tube, arrived with the sound of thunder at its mouth; and the multitude ranged round Stones Hill heartily united their shouts with those of the ten revelers hidden from view at the bottom of the gigantic Columbiad.

J. T. Maston was no longer master of himself. Whether he shouted or gesticulated, ate or drank most, would be a difficult matter to determine. At all events, he would not have given his place up for an empire, "not even if the cannon— loaded, primed, and fired at that very moment—were to blow him in pieces into the planetary world."

From the Earth to the Moon, Ch 15: THE FETE OF THE CASTING

CHAPTER XV --THE FETE OF THE CASTING
During the eight months which were employed in the work of excavation the preparatory works of the casting had been carried on simultaneously with extreme rapidity. A stranger arriving at Stones Hill would have been surprised at the spectacle offered to his view.

At 600 yards from the well, and circularly arranged around it as a central point, rose 1,200 reverberating ovens, each six feet in diameter, and separated from each other by an interval of three feet. The circumference occupied by these 1,200 ovens presented a length of two miles. Being all constructed on the same plan, each with its high quadrangular chimney, they produced a most singular effect.

It will be remembered that on their third meeting the committee had decided to use cast iron for the Columbiad, and in particular the white description. This metal, in fact, is the most tenacious, the most ductile, and the most malleable, and consequently suitable for all moulding operations; and when smelted with pit coal, is of superior quality for all engineering works requiring great resisting power, such as cannon, steam boilers, hydraulic presses, and the like.

Cast iron, however, if subjected to only one single fusion, is rarely sufficiently homogeneous; and it requires a second fusion completely to refine it by dispossessing it of its last earthly deposits. So long before being forwarded to Tampa Town, the iron ore, molten in the great furnaces of Coldspring, and brought into contact with coal and silicium heated to a high temperature, was carburized and transformed into cast iron. After this first operation, the metal was sent on to Stones Hill. They had, however, to deal with 136,000,000 pounds of iron, a quantity far too costly to send by railway. The cost of transport would have been double that of material. It appeared preferable to freight vessels at New York, and to load them with the iron in bars. This, however, required not less than sixty- eight vessels of 1,000 tons, a veritable fleet, which, quitting New York on the 3rd of May, on the 10th of the same month ascended the Bay of Espiritu Santo, and discharged their cargoes, without dues, in the port at Tampa Town. Thence the iron was transported by rail to Stones Hill, and about the middle of January this enormous mass of metal was delivered at its destination.

It will easily be understood that 1,200 furnaces were not too many to melt simultaneously these 60,000 tons of iron. Each of these furnaces contained nearly 140,000 pounds weight of metal. They were all built after the model of those which served for the casting of the Rodman gun; they were trapezoidal in shape, with a high elliptical arch. These furnaces, constructed of fireproof brick, were especially adapted for burning pit coal, with a flat bottom upon which the iron bars were laid. This bottom, inclined at an angle of 25 degrees, allowed the metal to flow into the receiving troughs; and the 1,200 converging trenches carried the molten metal down to the central well.

The day following that on which the works of the masonry and boring had been completed, Barbicane set to work upon the central mould. His object now was to raise within the center of the well, and with a coincident axis, a cylinder 900 feet high, and nine feet in diameter, which should exactly fill up the space reserved for the bore of the Columbiad. This cylinder was composed of a mixture of clay and sand, with the addition of a little hay and straw. The space left between the mould and the masonry was intended to be filled up by the molten metal, which would thus form the walls six feet in thickness. This cylinder, in order to maintain its equilibrium, had to be bound by iron bands, and firmly fixed at certain intervals by cross-clamps fastened into the stone lining; after the castings these would be buried in the block of metal, leaving no external projection.

This operation was completed on the 8th of July, and the run of the metal was fixed for the following day.

"This fete of the casting will be a grand ceremony," said J.
T. Maston to his friend Barbicane.

"Undoubtedly," said Barbicane; "but it will not be a public fete"

"What! will you not open the gates of the enclosure to all comers?"

"I must be very careful, Maston. The casting of the Columbiad is an extremely delicate, not to say a dangerous operation, and I should prefer its being done privately. At the discharge of the projectile, a fete if you like— till then, no!"

The president was right. The operation involved unforeseen dangers, which a great influx of spectators would have hindered him from averting. It was necessary to preserve complete freedom of movement. No one was admitted within the enclosure except a delegation of members of the Gun Club, who had made the voyage to Tampa Town. Among these was the brisk Bilsby, Tom Hunter, Colonel Blomsberry, Major Elphinstone, General Morgan, and the rest of the lot to whom the casting of the Columbiad was a matter of personal interest. J. T. Maston became their cicerone. He omitted no point of detail; he conducted them throughout the magazines, workshops, through the midst of the engines, and compelled them to visit the whole 1,200 furnaces one after the other. At the end of the twelve-hundredth visit they were pretty well knocked up.

The casting was to take place at twelve o'clock precisely. The previous evening each furnace had been charged with 114,000 pounds weight of metal in bars disposed cross-ways to each other, so as to allow the hot air to circulate freely between them. At daybreak the 1,200 chimneys vomited their torrents of flame into the air, and the ground was agitated with dull tremblings. As many pounds of metal as there were to cast, so many pounds of coal were there to burn. Thus there were 68,000 tons of coal which projected in the face of the sun a thick curtain of smoke. The heat soon became insupportable within the circle of furnaces, the rumbling of which resembled the rolling of thunder. The powerful ventilators added their continuous blasts and saturated with oxygen the glowing plates. The operation, to be successful, required to be conducted with great rapidity. On a signal given by a cannon-shot each furnace was to give vent to the molten iron and completely to empty itself. These arrangements made, foremen and workmen waited the preconcerted moment with an impatience mingled with a certain amount of emotion. Not a soul remained within the enclosure. Each superintendent took his post by the aperture of the run.

Barbicane and his colleagues, perched on a neighboring eminence, assisted at the operation. In front of them was a piece of artillery ready to give fire on the signal from the engineer. Some minutes before midday the first driblets of metal began to flow; the reservoirs filled little by little; and, by the time that the whole melting was completely accomplished, it was kept in abeyance for a few minutes in order to facilitate the separation of foreign substances.

Twelve o'clock struck! A gunshot suddenly pealed forth and shot its flame into the air. Twelve hundred melting-troughs were simultaneously opened and twelve hundred fiery serpents crept toward the central well, unrolling their incandescent curves. There, down they plunged with a terrific noise into a depth of 900 feet. It was an exciting and a magnificent spectacle. The ground trembled, while these molten waves, launching into the sky their wreaths of smoke, evaporated the moisture of the mould and hurled it upward through the vent-holes of the stone lining in the form of dense vapor-clouds. These artificial clouds unrolled their thick spirals to a height of 1,000 yards into the air. A savage, wandering somewhere beyond the limits of the horizon, might have believed that some new crater was forming in the bosom of Florida, although there was neither any eruption, nor typhoon, nor storm, nor struggle of the elements, nor any of those terrible phenomena which nature is capable of producing. No, it was man alone who had produced these reddish vapors, these gigantic flames worthy of a volcano itself, these tremendous vibrations resembling the shock of an earthquake, these reverberations rivaling those of hurricanes and storms; and it was his hand which precipitated into an abyss, dug by himself, a whole Niagara of molten metal!

From the Earth to the Moon, Ch 14: PICKAXE AND TROWEL

CHAPTER XIV: PICKAXE AND TROWEL
The same evening Barbicane and his companions returned to Tampa Town; and Murchison, the engineer, re-embarked on board the Tampico for New Orleans. His object was to enlist an army of workmen, and to collect together the greater part of the materials. The members of the Gun Club remained at Tampa Town, for the purpose of setting on foot the preliminary works by the aid of the people of the country.

Eight days after its departure, the Tampico returned into the bay of Espiritu Santo, with a whole flotilla of steamboats. Murchison had succeeded in assembling together fifteen hundred artisans. Attracted by the high pay and considerable bounties offered by the Gun Club, he had enlisted a choice legion of stokers, iron-founders, lime-burners, miners, brickmakers, and artisans of every trade, without distinction of color. As many of these people brought their families with them, their departure resembled a perfect emigration.

On the 31st of October, at ten o'clock in the morning, the troop disembarked on the quays of Tampa Town; and one may imagine the activity which pervaded that little town, whose population was thus doubled in a single day.

During the first few days they were busy discharging the cargo brought by the flotilla, the machines, and the rations, as well as a large number of huts constructed of iron plates, separately pieced and numbered. At the same period Barbicane laid the first sleepers of a railway fifteen miles in length, intended to unite Stones Hill with Tampa Town. On the first of November Barbicane quitted Tampa Town with a detachment of workmen; and on the following day the whole town of huts was erected round Stones Hill. This they enclosed with palisades; and in respect of energy and activity, it might have been mistaken for one of the great cities of the Union. Everything was placed under a complete system of discipline, and the works were commenced in most perfect order.

The nature of the soil having been carefully examined, by means of repeated borings, the work of excavation was fixed for the 4th of November.

On that day Barbicane called together his foremen and addressed them as follows: "You are well aware, my friends, of the object with which I have assembled you together in this wild part of Florida. Our business is to construct a cannon measuring nine feet in its interior diameter, six feet thick, and with a stone revetment of nineteen and a half feet in thickness. We have, therefore, a well of sixty feet in diameter to dig down to a depth of nine hundred feet. This great work must be completed within eight months, so that you have 2,543,400 cubic feet of earth to excavate in 255 days; that is to say, in round numbers, 2,000 cubic feet per day. That which would present no difficulty to a thousand navvies working in open country will be of course more troublesome in a comparatively confined space. However, the thing must be done, and I reckon for its accomplishment upon your courage as much as upon your skill."

At eight o'clock the next morning the first stroke of the pickaxe was struck upon the soil of Florida; and from that moment that prince of tools was never inactive for one moment in the hands of the excavators. The gangs relieved each other every three hours.

On the 4th of November fifty workmen commenced digging, in the very center of the enclosed space on the summit of Stones Hill, a circular hole sixty feet in diameter. The pickaxe first struck upon a kind of black earth, six inches in thickness, which was speedily disposed of. To this earth succeeded two feet of fine sand, which was carefully laid aside as being valuable for serving the casting of the inner mould. After the sand appeared some compact white clay, resembling the chalk of Great Britain, which extended down to a depth of four feet. Then the iron of the picks struck upon the hard bed of the soil; a kind of rock formed of petrified shells, very dry, very solid, and which the picks could with difficulty penetrate. At this point the excavation exhibited a depth of six and a half feet and the work of the masonry was begun.

At the bottom of the excavation they constructed a wheel of oak, a kind of circle strongly bolted together, and of immense strength. The center of this wooden disc was hollowed out to a diameter equal to the exterior diameter of the Columbiad. Upon this wheel rested the first layers of the masonry, the stones of which were bound together by hydraulic cement, with irresistible tenacity. The workmen, after laying the stones from the circumference to the center, were thus enclosed within a kind of well twenty-one feet in diameter. When this work was accomplished, the miners resumed their picks and cut away the rock from underneath the wheel itself, taking care to support it as they advanced upon blocks of great thickness. At every two feet which the hole gained in depth they successively withdrew the blocks. The wheel then sank little by little, and with it the massive ring of masonry, on the upper bed of which the masons labored incessantly, always reserving some vent holes to permit the escape of gas during the operation of the casting.

This kind of work required on the part of the workmen extreme nicety and minute attention. More than one, in digging underneath the wheel, was dangerously injured by the splinters of stone. But their ardor never relaxed, night or day. By day they worked under the rays of the scorching sun; by night, under the gleam of the electric light. The sounds of the picks against the rock, the bursting of mines, the grinding of the machines, the wreaths of smoke scattered through the air, traced around Stones Hill a circle of terror which the herds of buffaloes and the war parties of the Seminoles never ventured to pass. Nevertheless, the works advanced regularly, as the steam-cranes actively removed the rubbish. Of unexpected obstacles there was little account; and with regard to foreseen difficulties, they were speedily disposed of.

At the expiration of the first month the well had attained the depth assigned for that lapse of time, namely, 112 feet. This depth was doubled in December, and trebled in January.

During the month of February the workmen had to contend with a sheet of water which made its way right across the outer soil. It became necessary to employ very powerful pumps and compressed-air engines to drain it off, so as to close up the orifice from whence it issued; just as one stops a leak on board ship. They at last succeeded in getting the upper hand of these untoward streams; only, in consequence of the loosening of the soil, the wheel partly gave way, and a slight partial settlement ensued. This accident cost the life of several workmen.

No fresh occurrence thenceforward arrested the progress of the operation; and on the tenth of June, twenty days before the expiration of the period fixed by Barbicane, the well, lined throughout with its facing of stone, had attained the depth of 900 feet. At the bottom the masonry rested upon a massive block measuring thirty feet in thickness, while on the upper portion it was level with the surrounding soil.

President Barbicane and the members of the Gun Club warmly congratulated their engineer Murchison; the cyclopean work had been accomplished with extraordinary rapidity.

During these eight months Barbicane never quitted Stones Hill for a single instant. Keeping ever close by the work of excavation, he busied himself incessantly with the welfare and health of his workpeople, and was singularly fortunate in warding off the epidemics common to large communities of men, and so disastrous in those regions of the globe which are exposed to the influences of tropical climates.

Many workmen, it is true, paid with their lives for the rashness inherent in these dangerous labors; but these mishaps are impossible to be avoided, and they are classed among the details with which the Americans trouble themselves but little. They have in fact more regard for human nature in general than for the individual in particular.

Nevertheless, Barbicane professed opposite principles to these, and put them in force at every opportunity. So, thanks to his care, his intelligence, his useful intervention in all difficulties, his prodigious and humane sagacity, the average of accidents did not exceed that of transatlantic countries, noted for their excessive precautions— France, for instance, among others, where they reckon about one accident for every two hundred thousand francs of work.

From the Earth to the Moon, Ch 13: STONES HILL

CHAPTER XIII--STONES HILL
When the decision was arrived at by the Gun Club, to the disparagement of Texas, every one in America, where reading is a universal acquirement, set to work to study the geography of Florida. Never before had there been such a sale for works like "Bertram's Travels in Florida," "Roman's Natural History of East and West Florida," "William's Territory of Florida," and "Cleland on the Cultivation of the Sugar-Cane in Florida." It became necessary to issue fresh editions of these works.

Barbicane had something better to do than to read. He desired to see things with his own eyes, and to mark the exact position of the proposed gun. So, without a moment's loss of time, he placed at the disposal of the Cambridge Observatory the funds necessary for the construction of a telescope, and entered into negotiations with the house of Breadwill and Co., of Albany, for the construction of an aluminum projectile of the required size. He then quitted Baltimore, accompanied by J. T. Maston, Major Elphinstone, and the manager of the Coldspring factory.

On the following day, the four fellow-travelers arrived at New Orleans. There they immediately embarked on board the Tampico, a despatch-boat belonging to the Federal navy, which the government had placed at their disposal; and, getting up steam, the banks of Louisiana speedily disappeared from sight.

The passage was not long. Two days after starting, the Tampico, having made four hundred and eighty miles, came in sight of the coast of Florida. On a nearer approach Barbicane found himself in view of a low, flat country of somewhat barren aspect. After coasting along a series of creeks abounding in lobsters and oysters, the Tampico entered the bay of Espiritu Santo, where she finally anchored in a small natural harbor, formed by the embouchure of the River Hillisborough, at seven P.M., on the 22d of October.

Our four passengers disembarked at once. "Gentlemen," said Barbicane, "we have no time to lose; tomorrow we must obtain horses, and proceed to reconnoiter the country."

Barbicane had scarcely set his foot on shore when three thousand of the inhabitants of Tampa Town came forth to meet him, an honor due to the president who had signalized their country by his choice.

Declining, however, every kind of ovation, Barbicane ensconced himself in a room of the Franklin Hotel.

On the morrow some of the small horses of the Spanish breed, full of vigor and of fire, stood snorting under his windows; but instead of four steeds, here were fifty, together with their riders. Barbicane descended with his three fellow- travelers; and much astonished were they all to find themselves in the midst of such a cavalcade. He remarked that every horseman carried a carbine slung across his shoulders and pistols in his holsters.

On expressing his surprise at these preparations, he was speedily enlightened by a young Floridan, who quietly said:

"Sir, there are Seminoles there."

"What do you mean by Seminoles?"

"Savages who scour the prairies. We thought it best, therefore, to escort you on your road."

"Pooh!" cried J. T. Maston, mounting his steed.

"All right," said the Floridan; "but it is true enough, nevertheless."

"Gentlemen," answered Barbicane, "I thank you for your kind attention; but it is time to be off."

It was five A.M. when Barbicane and his party, quitting Tampa Town, made their way along the coast in the direction of Alifia Creek. This little river falls into Hillisborough Bay twelve miles above Tampa Town. Barbicane and his escort coasted along its right bank to the eastward. Soon the waves of the bay disappeared behind a bend of rising ground, and the Floridan "champagne" alone offered itself to view.

Florida, discovered on Palm Sunday, in 1512, by Juan Ponce de Leon, was originally named Pascha Florida. It little deserved that designation, with its dry and parched coasts. But after some few miles of tract the nature of the soil gradually changes and the country shows itself worthy of the name. Cultivated plains soon appear, where are united all the productions of the northern and tropical floras, terminating in prairies abounding with pineapples and yams, tobacco, rice, cotton-plants, and sugar-canes, which extend beyond reach of sight, flinging their riches broadcast with careless prodigality.

Barbicane appeared highly pleased on observing the progressive elevation of the land; and in answer to a question of J. T. Maston, replied:

"My worthy friend, we cannot do better than sink our Columbiad in these high grounds."

"To get nearer the moon, perhaps?" said the secretary of the Gun Club.

"Not exactly," replied Barbicane, smiling; "do you not see that among these elevated plateaus we shall have a much easier work of it? No struggles with the water-springs, which will save us long expensive tubings; and we shall be working in daylight instead of down a deep and narrow well. Our business, then, is to open our trenches upon ground some hundreds of yards above the level of the sea."

"You are right, sir," struck in Murchison, the engineer; "and, if I mistake not, we shall ere long find a suitable spot for our purpose."

"I wish we were at the first stroke of the pickaxe," said the president.

"And I wish we were at the last," cried J. T. Maston.

About ten A.M. the little band had crossed a dozen miles. To fertile plains succeeded a region of forests. There perfumes of the most varied kinds mingled together in tropical profusion. These almost impenetrable forests were composed of pomegranates, orange-trees, citrons, figs, olives, apricots, bananas, huge vines, whose blossoms and fruits rivaled each other in color and perfume. Beneath the odorous shade of these magnificent trees fluttered and warbled a little world of brilliantly plumaged birds.

J. T. Maston and the major could not repress their admiration on finding themselves in the presence of the glorious beauties of this wealth of nature. President Barbicane, however, less sensitive to these wonders, was in haste to press forward; the very luxuriance of the country was displeasing to him. They hastened onward, therefore, and were compelled to ford several rivers, not without danger, for they were infested with huge alligators from fifteen to eighteen feet long. Maston courageously menaced them with his steel hook, but he only succeeded in frightening some pelicans and teal, while tall flamingos stared stupidly at the party.

At length these denizens of the swamps disappeared in their turn; smaller trees became thinly scattered among less dense thickets— a few isolated groups detached in the midst of endless plains over which ranged herds of startled deer.

"At last," cried Barbicane, rising in his stirrups, "here we are at the region of pines!"

"Yes! and of savages too," replied the major.

In fact, some Seminoles had just came in sight upon the horizon; they rode violently backward and forward on their fleet horses, brandishing their spears or discharging their guns with a dull report. These hostile demonstrations, however, had no effect upon Barbicane and his companions.

They were then occupying the center of a rocky plain, which the sun scorched with its parching rays. This was formed by a considerable elevation of the soil, which seemed to offer to the members of the Gun Club all the conditions requisite for the construction of their Columbiad.

"Halt!" said Barbicane, reining up. "Has this place any local appellation?"

"It is called Stones Hill," replied one of the Floridans.

Barbicane, without saying a word, dismounted, seized his instruments, and began to note his position with extreme exactness. The little band, drawn up in the rear, watched his proceedings in profound silence.

At this moment the sun passed the meridian. Barbicane, after a few moments, rapidly wrote down the result of his observations, and said:

"This spot is situated eighteen hundred feet above the level of the sea, in 27@ 7' N. lat. and 5@ 7' W. long. of the meridian of Washington. It appears to me by its rocky and barren character to offer all the conditions requisite for our experiment. On that plain will be raised our magazines, workshops, furnaces, and workmen's huts; and here, from this very spot," said he, stamping his foot on the summit of Stones Hill, "hence shall our projectile take its flight into the regions of the Solar World."

FICTION: From the Earth to the Moon, Ch 7: THE HYMN OF THE CANNON-BALL

CHAPTER VI
THE HYMN OF THE CANNON-BALL

The Observatory of Cambridge in its memorable letter had treated the question from a purely astronomical point of view. The mechanical part still remained.

President Barbicane had, without loss of time, nominated a working committee of the Gun Club. The duty of this committee was to resolve the three grand questions of the cannon, the projectile, and the powder. It was composed of four members of great technical knowledge, Barbicane (with a casting vote in case of equality), General Morgan, Major Elphinstone, and J. T. Maston, to whom were confided the functions of secretary.

On the 8th of October the committee met at the house of President Barbicane, 3 Republican Street. The meeting was opened by the president himself.

"Gentlemen," said he, "we have to resolve one of the most important problems in the whole of the noble science of gunnery. It might appear, perhaps, the most logical course to devote our first meeting to the discussion of the engine to be employed. Nevertheless, after mature consideration, it has appeared to me that the question of the projectile must take precedence of that of the cannon, and that the dimensions of the latter must necessarily depend on those of the former."

"Suffer me to say a word," here broke in J. T. Maston. Permission having been granted, "Gentlemen," said he with an inspired accent, "our president is right in placing the question of the projectile above all others. The ball we are about to discharge at the moon is our ambassador to her, and I wish to consider it from a moral point of view. The cannon-ball, gentlemen, to my mind, is the most magnificent manifestation of human power. If Providence has created the stars and the planets, man has called the cannon-ball into existence. Let Providence claim the swiftness of electricity and of light, of the stars, the comets, and the planets, of wind and sound— we claim to have invented the swiftness of the cannon-ball, a hundred times superior to that of the swiftest horses or railway train. How glorious will be the moment when, infinitely exceeding all hitherto attained velocities, we shall launch our new projectile with the rapidity of seven miles a second! Shall it not, gentlemen— shall it not be received up there with the honors due to a terrestrial ambassador?"

Overcome with emotion the orator sat down and applied himself to a huge plate of sandwiches before him.

"And now," said Barbicane, "let us quit the domain of poetry and come direct to the question."

"By all means," replied the members, each with his mouth full of sandwich.

"The problem before us," continued the president, "is how to communicate to a projectile a velocity of 12,000 yards per second. Let us at present examine the velocities hitherto attained. General Morgan will be able to enlighten us on this point."

"And the more easily," replied the general, "that during the war I was a member of the committee of experiments. I may say, then, that the 100-pounder Dahlgrens, which carried a distance of 5,000 yards, impressed upon their projectile an initial velocity of 500 yards a second. The Rodman Columbiad threw a shot weighing half a ton a distance of six miles, with a velocity of 800 yards per second— a result which Armstrong and Palisser have never obtained in England."

"This," replied Barbicane, "is, I believe, the maximum velocity ever attained?"
"It is so," replied the general.

"Ah!" groaned J. T. Maston, "if my mortar had not burst——"

"Yes," quietly replied Barbicane, "but it did burst. We must take, then, for our starting point, this velocity of 800 yards. We must increase it twenty-fold. Now, reserving for another discussion the means of producing this velocity, I will call your attention to the dimensions which it will be proper to assign to the shot. You understand that we have nothing to do here with projectiles weighing at most but half a ton."

"Why not?" demanded the major.

"Because the shot," quickly replied J. T. Maston, "must be big enough to attract the attention of the inhabitants of the moon, if there are any?"

"Yes," replied Barbicane, "and for another reason more important still."
"What mean you?" asked the major.

"I mean that it is not enough to discharge a projectile, and then take no further notice of it; we must follow it throughout its course, up to the moment when it shall reach its goal."

"What?" shouted the general and the major in great surprise.

"Undoubtedly," replied Barbicane composedly, "or our experiment would produce no result."

"But then," replied the major, "you will have to give this projectile enormous dimensions."

"No! Be so good as to listen. You know that optical instruments have acquired great perfection; with certain instruments we have succeeded in obtaining enlargements of 6,000 times and reducing the moon to within forty miles' distance. Now, at this distance, any objects sixty feet square would be perfectly visible.

"If, then, the penetrative power of telescopes has not been further increased, it is because that power detracts from their light; and the moon, which is but a reflecting mirror, does not give back sufficient light to enable us to perceive objects of lesser magnitude."

"Well, then, what do you propose to do?" asked the general.

"Would you give your projectile a diameter of sixty feet?"

"Not so."

"Do you intend, then, to increase the luminous power of the moon?"

"Exactly so. If I can succeed in diminishing the density of the atmosphere through which the moon's light has to travel I shall have rendered her light more intense. To effect that object it will be enough to establish a telescope on some elevated mountain. That is what we will do."

"I give it up," answered the major. "You have such a way of simplifying things. And what enlargement do you expect to obtain in this way?"

"One of 48,000 times, which should bring the moon within an apparent distance of five miles; and, in order to be visible, objects need not have a diameter of more than nine feet."

"So, then," cried J. T. Maston, "our projectile need not be more than nine feet in diameter."

"Let me observe, however," interrupted Major Elphinstone, "this will involve a weight such as——"

"My dear major," replied Barbicane, "before discussing its weight permit me to enumerate some of the marvels which our ancestors have achieved in this respect. I don't mean to pretend that the science of gunnery has not advanced, but it is as well to bear in mind that during the middle ages they obtained results more surprising, I will venture to say, than ours. For instance, during the siege of Constantinople by Mahomet II., in 1453, stone shot of 1,900 pounds weight were employed. At Malta, in the time of the knights, there was a gun of the fortress of St. Elmo which threw a projectile weighing 2,500 pounds. And, now, what is the extent of what we have seen ourselves? Armstrong guns discharging shot of 500 pounds, and the Rodman guns projectiles of half a ton! It seems, then, that if projectiles have gained in range, they have lost far more in weight. Now, if we turn our efforts in that direction, we ought to arrive, with the progress on science, at ten times the weight of the shot of Mahomet II. and the Knights of Malta."

"Clearly," replied the major; "but what metal do you calculate upon employing?"
"Simply cast iron," said General Morgan.

"But," interrupted the major, "since the weight of a shot is proportionate to its volume, an iron ball of nine feet in diameter would be of tremendous weight."
"Yes, if it were solid, not if it were hollow."

"Hollow? then it would be a shell?"

"Yes, a shell," replied Barbicane; "decidely it must be. A solid shot of 108 inches would weigh more than 200,000 pounds, a weight evidently far too great. Still, as we must reserve a certain stability for our projectile, I propose to give it a weight of 20,000 pounds."

"What, then, will be the thickness of the sides?" asked the major.

"If we follow the usual proportion," replied Morgan, "a diameter of 108 inches would require sides of two feet thickness, or less."

"That would be too much," replied Barbicane; "for you will observe that the question is not that of a shot intended to pierce an iron plate; it will suffice to give it sides strong enough to resist the pressure of the gas. The problem, therefore, is this— What thickness ought a cast-iron shell to have in order not to weight more than 20,000 pounds? Our clever secretary will soon enlighten us upon this point."
"Nothing easier." replied the worthy secretary of the committee; and, rapidly tracing a few algebraical formulae upon paper, among which n^2 and x^2 frequently appeared, he presently said:

"The sides will require a thickness of less than two inches."

"Will that be enough?" asked the major doubtfully.

"Clearly not!" replied the president.

"What is to be done, then?" said Elphinstone, with a puzzled air.
"Employ another metal instead of iron."

"Copper?" said Morgan.

"No! that would be too heavy. I have better than that to offer."
"What then?" asked the major.

"Aluminum!" replied Barbicane.

"Aluminum?" cried his three colleagues in chorus.

"Unquestionably, my friends. This valuable metal possesses the whiteness of silver, the indestructibility of gold, the tenacity of iron, the fusibility of copper, the lightness of glass. It is easily wrought, is very widely distributed, forming the base of most of the rocks, is three times lighter than iron, and seems to have been created for the express purpose of furnishing us with the material for our projectile."

"But, my dear president," said the major, "is not the cost price of aluminum extremely high?"

"It was so at its first discovery, but it has fallen now to nine dollars a pound."
"But still, nine dollars a pound!" replied the major, who was not willing readily to give in; "even that is an enormous price."

"Undoubtedly, my dear major; but not beyond our reach."

"What will the projectile weigh then?" asked Morgan.

"Here is the result of my calculations," replied Barbicane. "A shot of 108 inches in diameter, and twelve inches in thickness, would weigh, in cast-iron, 67,440 pounds; cast in aluminum, its weight will be reduced to 19,250 pounds."

"Capital!" cried the major; "but do you know that, at nine dollars a pound, this projectile will cost——"

"One hundred and seventy-three thousand and fifty dollars ($173,050). I know it quite well. But fear not, my friends; the money will not be wanting for our enterprise. I will answer for it. Now what say you to aluminum, gentlemen?"
"Adopted!" replied the three members of the committee. So ended the first meeting. The question of the projectile was definitely settled.

FICTION: From the Earth to the Moon, Ch 6: PERMISSIVE LIMITS OF IGNORANCE AND BELIEF IN THE UNITED STATES

CHAPTER VI --PERMISSIVE LIMITS OF IGNORANCE AND BELIEF IN THE UNITED STATES
The immediate result of Barbicane's proposition was to place upon the orders of the day all the astronomical facts relative to the Queen of the Night. Everybody set to work to study assiduously. One would have thought that the moon had just appeared for the first time, and that no one had ever before caught a glimpse of her in the heavens. The papers revived all the old anecdotes in which the "sun of the wolves" played a part; they recalled the influences which the ignorance of past ages ascribed to her; in short, all America was seized with selenomania, or had become moon-mad.

The scientific journals, for their part, dealt more especially with the questions which touched upon the enterprise of the Gun Club. The letter of the Observatory of Cambridge was published by them, and commented upon with unreserved approval.

Until that time most people had been ignorant of the mode in which the distance which separates the moon from the earth is calculated. They took advantage of this fact to explain to them that this distance was obtained by measuring the parallax of the moon. The term parallax proving "caviare to the general," they further explained that it meant the angle formed by the inclination of two straight lines drawn from either extremity of the earth's radius to the moon. On doubts being expressed as to the correctness of this method, they immediately proved that not only was the mean distance 234,347 miles, but that astronomers could not possibly be in error in their estimate by more than seventy miles either way.

To those who were not familiar with the motions of the moon, they demonstrated that she possesses two distinct motions, the first being that of rotation upon her axis, the second being that of revolution round the earth, accomplishing both together in an equal period of time, that is to say, in twenty-seven and one-third days.

The motion of rotation is that which produces day and night on the surface of the moon; save that there is only one day and one night in the lunar month, each lasting three hundred and fifty-four and one-third hours. But, happily for her, the face turned toward the terrestrial globe is illuminated by it with an intensity equal to that of fourteen moons. As to the other face, always invisible to us, it has of necessity three hundred and fifty-four hours of absolute night, tempered only by that "pale glimmer which falls upon it from the stars."

Some well-intentioned, but rather obstinate persons, could not at first comprehend how, if the moon displays invariably the same face to the earth during her revolution, she can describe one turn round herself. To such they answered, "Go into your dining-room, and walk round the table in such a way as to always keep your face turned toward the center; by the time you will have achieved one complete round you will have completed one turn around yourself, since your eye will have traversed successively every point of the room. Well, then, the room is the heavens, the table is the earth, and the moon is yourself." And they would go away delighted.

So, then the moon displays invariably the same face to the earth; nevertheless, to be quite exact, it is necessary to add that, in consequence of certain fluctuations of north and south, and of west and east, termed her libration, she permits rather more than half, that is to say, five-sevenths, to be seen.

As soon as the ignoramuses came to understand as much as the director of the observatory himself knew, they began to worry themselves regarding her revolution round the earth, whereupon twenty scientific reviews immediately came to the rescue. They pointed out to them that the firmament, with its infinitude of stars, may be considered as one vast dial-plate, upon which the moon travels, indicating the true time to all the inhabitants of the earth; that it is during this movement that the Queen of Night exhibits her different phases; that the moon is full when she is in opposition with the sun, that is when the three bodies are on the same straight line, the earth occupying the center; that she is new when she is in conjunction with the sun, that is, when she is between it and the earth; and, lastly that she is in her first or last quarter, when she makes with the sun and the earth an angle of which she herself occupies the apex.

Regarding the altitude which the moon attains above the horizon, the letter of the Cambridge Observatory had said all that was to be said in this respect. Everyone knew that this altitude varies according to the latitude of the observer. But the only zones of the globe in which the moon passes the zenith, that is, the point directly over the head of the spectator, are of necessity comprised between the twenty-eighth parallels and the equator. Hence the importance of the advice to try the experiment upon some point of that part of the globe, in order that the projectile might be discharged perpendicularly, and so the soonest escape the action of gravitation. This was an essential condition to the success of the enterprise, and continued actively to engage the public attention.

Regarding the path described by the moon in her revolution round the earth, the Cambridge Observatory had demonstrated that this path is a re-entering curve, not a perfect circle, but an ellipse, of which the earth occupies one of the foci. It was also well understood that it is farthest removed from the earth during its apogee, and approaches most nearly to it at its perigee.

Such was then the extent of knowledge possessed by every American on the subject, and of which no one could decently profess ignorance. Still, while these principles were being rapidly disseminated many errors and illusory fears proved less easy to eradicate.

For instance, some worthy persons maintained that the moon was an ancient comet which, in describing its elongated orbit round the sun, happened to pass near the earth, and became confined within her circle of attraction. These drawing-room astronomers professed to explain the charred aspect of the moon-- a disaster which they attributed to the intensity of the solar heat; only, on being reminded that comets have an atmosphere, and that the moon has little or none, they were fairly at a loss for a reply.

Others again, belonging to the doubting class, expressed certain fears as to the position of the moon. They had heard it said that, according to observations made in the time of the Caliphs, her revolution had become accelerated in a certain degree. Hence they concluded, logically enough, that an acceleration of motion ought to be accompanied by a corresponding diminution in the distance separating the two bodies; and that, supposing the double effect to be continued to infinity, the moon would end by one day falling into the earth. However, they became reassured as to the fate of future generations on being apprised that, according to the calculations of Laplace, this acceleration of motion is confined within very restricted limits, and that a proportional diminution of speed will be certain to succeed it. So, then, the stability of the solar system would not be deranged in ages to come.

There remains but the third class, the superstitious. These worthies were not content merely to rest in ignorance; they must know all about things which had no existence whatever, and as to the moon, they had long known all about her. One set regarded her disc as a polished mirror, by means of which people could see each other from different points of the earth and interchange their thoughts. Another set pretended that out of one thousand new moons that had been observed, nine hundred and fifty had been attended with remarkable disturbances, such as cataclysms, revolutions, earthquakes, the deluge, etc. Then they believed in some mysterious influence exercised by her over human destinies-- that every Selenite was attached to some inhabitant of the earth by a tie of sympathy; they maintained that the entire vital system is subject to her control, etc. But in time the majority renounced these vulgar errors, and espoused the true side of the question. As for the Yankees, they had no other ambition than to take possession of this new continent of the sky, and to plant upon the summit of its highest elevation the star- spangled banner of the United States of America.

FICTION: From the Earth to the Moon, Ch 5: THE ROMANCE OF THE MOON

CHAPTER V --THE ROMANCE OF THE MOON
An observer endued with an infinite range of vision, and placed in that unknown center around which the entire world revolves, might have beheld myriads of atoms filling all space during the chaotic epoch of the universe. Little by little, as ages went on, a change took place; a general law of attraction manifested itself, to which the hitherto errant atoms became obedient: these atoms combined together chemically according to their affinities, formed themselves into molecules, and composed those nebulous masses with which the depths of the heavens are strewed. These masses became immediately endued with a rotary motion around their own central point. This center, formed of indefinite molecules, began to revolve around its own axis during its gradual condensation; then, following the immutable laws of mechanics, in proportion as its bulk diminished by condensation, its rotary motion became accelerated, and these two effects continuing, the result was the formation of one principal star, the center of the nebulous mass.

By attentively watching, the observer would then have perceived the other molecules of the mass, following the example of this central star, become likewise condensed by gradually accelerated rotation, and gravitating round it in the shape of innumerable stars. Thus was formed the Nebulae, of which astronomers have reckoned up nearly 5,000.

Among these 5,000 nebulae there is one which has received the name of the Milky Way, and which contains eighteen millions of stars, each of which has become the center of a solar world.

If the observer had then specially directed his attention to one of the more humble and less brilliant of these stellar bodies, a star of the fourth class, that which is arrogantly called the Sun, all the phenomena to which the formation of the Universe is to be ascribed would have been successively fulfilled before his eyes. In fact, he would have perceived this sun, as yet in the gaseous state, and composed of moving molecules, revolving round its axis in order to accomplish its work of concentration. This motion, faithful to the laws of mechanics, would have been accelerated with the diminution of its volume; and a moment would have arrived when the centrifugal force would have overpowered the centripetal, which causes the molecules all to tend toward the center.

Another phenomenon would now have passed before the observer's eye, and the molecules situated on the plane of the equator, escaping like a stone from a sling of which the cord had suddenly snapped, would have formed around the sun sundry concentric rings resembling that of Saturn. In their turn, again, these rings of cosmical matter, excited by a rotary motion about the central mass, would have been broken up and decomposed into secondary nebulosities, that is to say, into planets. Similarly he would have observed these planets throw off one or more rings each, which became the origin of the secondary bodies which we call satellites.

Thus, then, advancing from atom to molecule, from molecule to nebulous mass, from that to principal star, from star to sun, from sun to planet, and hence to satellite, we have the whole series of transformations undergone by the heavenly bodies during the first days of the world.

Now, of those attendant bodies which the sun maintains in their elliptical orbits by the great law of gravitation, some few in turn possess satellites. Uranus has eight, Saturn eight, Jupiter four, Neptune possibly three, and the Earth one. This last, one of the least important of the entire solar system, we call the Moon; and it is she whom the daring genius of the Americans professed their intention of conquering.

The moon, by her comparative proximity, and the constantly varying appearances produced by her several phases, has always occupied a considerable share of the attention of the inhabitants of the earth.

From the time of Thales of Miletus, in the fifth century B.C., down to that of Copernicus in the fifteenth and Tycho Brahe in the sixteenth century A.D., observations have been from time to time carried on with more or less correctness, until in the present day the altitudes of the lunar mountains have been determined with exactitude. Galileo explained the phenomena of the lunar light produced during certain of her phases by the existence of mountains, to which he assigned a mean altitude of 27,000 feet. After him Hevelius, an astronomer of Dantzic, reduced the highest elevations to 15,000 feet; but the calculations of Riccioli brought them up again to 21,000 feet.

At the close of the eighteenth century Herschel, armed with a powerful
telescope, considerably reduced the preceding measurements. He assigned a height of 11,400 feet to the maximum elevations, and reduced the mean of the different altitudes to little more than 2,400 feet. But Herschel's calculations were in their turn corrected by the observations of Halley, Nasmyth, Bianchini, Gruithuysen, and others; but it was reserved for the labors of Boeer and Maedler finally to solve the question. They succeeded in measuring 1,905 different elevations, of which six exceed 15,000 feet, and twenty-two exceed 14,400 feet. The highest summit of all towers to a height of 22,606 feet above the surface of the lunar disc. At the same period the examination of the moon was completed. She appeared completely riddled with craters, and her essentially volcanic character was apparent at each observation. By the absence of refraction in the rays of the planets occulted by her we conclude that she is absolutely devoid of an atmosphere. The absence of air entails the absence of water. It became, therefore, manifest that the Selenites, to support life under such conditions, must possess a special organization of their own, must differ remarkably from the inhabitants of the earth.

At length, thanks to modern art, instruments of still higher perfection searched the moon without intermission, not leaving a single point of her surface unexplored; and notwithstanding that her diameter measures 2,150 miles, her surface equals the one-fifteenth part of that of our globe, and her bulk the one-forty-ninth part of that of the terrestrial spheroid—not one of her secrets was able to escape the eyes of the astronomers; and these skillful men of science carried to an even greater degree their prodigious observations.

Thus they remarked that, during full moon, the disc appeared scored in certain parts with white lines; and, during the phases, with black. On prosecuting the study of these with still greater precision, they succeeded in obtaining an exact account of the nature of these lines. They were long and narrow furrows sunk between parallel ridges, bordering generally upon the edges of the craters. Their length varied between ten and 100 miles, and their width was about 1,600 yards. Astronomers called them chasms, but they could not get any further. Whether these chasms were the dried-up beds of ancient rivers or not they were unable thoroughly to ascertain.

The Americans, among others, hoped one day or other to determine this geological question. They also undertook to examine the true nature of that system of parallel ramparts discovered on the moon's surface by Gruithuysen, a learned professor of Munich, who considered them to be "a system of fortifications thrown up by the Selenitic engineers." These two points, yet obscure, as well as others, no doubt, could not be definitely settled except by direct communication with the moon.

Regarding the degree of intensity of its light, there was nothing more to learn on this point. It was known that it is 300,000 times weaker than that of the sun, and that its heat had no appreciable effect upon the thermometer. As to the phenomenon known as the "ashy light," it is explained naturally by the effect of the transmission of the solar rays from the earth to the moon, which give the appearance of completeness to the lunar disc, while it presents itself under the crescent form during its first and last phases.

Such was the state of knowledge acquired regarding the earth's satellite, which the Gun Club undertook to perfect in all its aspects, cosmographic, geological, political, and moral.

FICTION: From the Earth to the Moon Ch 4: REPLY FROM THE OBSERVATORY OF CAMBRIDGE

CHAPTER IV -- REPLY FROM THE OBSERVATORY OF CAMBRIDGE
Barbicane, however, lost not one moment amid all the enthusiasm of which he had become the object. His first care was to reassemble his colleagues in the board-room of the Gun Club. There, after some discussion, it was agreed to consult the astronomers regarding the astronomical part of the enterprise. Their reply once ascertained, they could then discuss the mechanical means, and nothing should be wanting to ensure the success of this great experiment.

A note couched in precise terms, containing special interrogatories, was then drawn up and addressed to the Observatory of Cambridge in Massachusetts. This city, where the first university of the United States was founded, is justly celebrated for its astronomical staff. There are to be found assembled all the most eminent men of science. Here is to be seen at work that powerful telescope which enabled Bond to resolve the nebula of Andromeda, and Clarke to discover the satellite of Sirius. This celebrated institution fully justified on all points the confidence reposed in it by the Gun Club.

So, after two days, the reply so impatiently awaited was placed in the hands of President Barbicane.

It was couched in the following terms:

The Director of the Cambridge Observatory to the President of the Gun Club at Baltimore.

CAMBRIDGE, October 7.
On the receipt of your favor of the 6th instant, addressed to the Observatory of Cambridge in the name of the members of the Baltimore Gun Club, our staff was immediately called together, and it was judged expedient to reply as follows:

The questions which have been proposed to it are these--

"1. Is it possible to transmit a projectile up to the moon?

"2. What is the exact distance which separates the earth from its satellite?

"3. What will be the period of transit of the projectile when endowed with sufficient initial velocity? and, consequently, at what moment ought it to be discharged in order that it may touch the moon at a particular point?

"4. At what precise moment will the moon present herself in the most favorable position to be reached by the projectile?

"5. What point in the heavens ought the cannon to be aimed at which is intended to discharge the projectile?

"6. What place will the moon occupy in the heavens at the moment
of the projectile's departure?"

Regarding the first question, "Is it possible to transmit a projectile up to the moon?"

Answer: Yes; provided it possess an initial velocity of 1,200 yards per second; calculations prove that to be sufficient. In proportion as we recede from the earth the action of gravitation diminishes in the inverse ratio of the square of the distance; that is to say, at three times a given distance the action is nine times less. Consequently, the weight of a shot will decrease, and will become reduced to zero at the instant that the attraction of the moon exactly counterpoises that of the earth; that is to say at 47/52 of its passage. At that instant the projectile will have no weight whatever; and, if it passes that point, it will fall into the moon by the sole effect of the lunar attraction. The theoretical possibility of the experiment is therefore absolutely demonstrated; its success must depend upon the power of the engine employed.

As to the second question, "What is the exact distance which separates the earth from its satellite?"

Answer: The moon does not describe a circle round the earth, but rather an ellipse, of which our earth occupies one of the foci; the consequence, therefore, is, that at certain times it approaches nearer to, and at others it recedes farther from, the earth; in astronomical language, it is at one time in apogee, at another in perigee. Now the difference between its greatest and its least distance is too considerable to be left out of consideration. In point of fact, in its apogee the moon is 247,552 miles, and in its perigee, 218,657 miles only distant; a fact which makes a difference of 28,895 miles, or more than one-ninth of the entire distance. The perigee distance, therefore, is that which ought to serve as the basis of all calculations.

To the third question.

Answer: If the shot should preserve continuously its initial velocity of 12,000 yards per second, it would require little more than nine hours to reach its destination; but, inasmuch as that initial velocity will be continually decreasing, it will occupy 300,000 seconds, that is 83hrs. 20m. in reaching the point where the attraction of the earth and moon will be in equilibrio. From this point it will fall into the moon in 50,000 seconds, or 13hrs. 53m. 20sec. It will be desirable, therefore, to discharge it 97hrs. 13m. 20sec. before the arrival of the moon at the point aimed at.

Regarding question four, "At what precise moment will the moon present herself in the most favorable position, etc.?"

Answer: After what has been said above, it will be necessary, first of all, to choose the period when the moon will be in perigee, and also the moment when she will be crossing the zenith, which latter event will further diminish the entire distance by a length equal to the radius of the earth, i. e. 3,919 miles; the result of which will be that the final passage remaining to be accomplished will be 214,976 miles. But although the moon passes her perigee every month, she does not reach the zenith always at exactly the same moment. She does not appear under these two conditions simultaneously, except at long intervals of time. It will be necessary, therefore, to wait for the moment when her passage in perigee shall coincide with that in the zenith. Now, by a fortunate circumstance, on the 4th of December in the ensuing year the moon will present these two conditions. At midnight she will be in perigee, that is, at her shortest distance from the earth, and at the same moment she will be crossing the zenith.

On the fifth question, "At what point in the heavens ought the cannon to be aimed?"

Answer: The preceding remarks being admitted, the cannon ought to be pointed to the zenith of the place. Its fire, therefore, will be perpendicular to the plane of the horizon; and the projectile will soonest pass beyond the range of the terrestrial attraction. But, in order that the moon should reach the zenith of a given place, it is necessary that the place should not exceed in latitude the declination of the luminary; in other words, it must be comprised within the degrees 0' and 28' of lat. N. or S. In every other spot the fire must necessarily be oblique, which would seriously militate against the success of the experiment.

As to the sixth question, "What place will the moon occupy in the heavens at the moment of the projectile's departure?"

Answer: At the moment when the projectile shall be discharged into space, the moon, which travels daily forward 13@ 10' 35'', will be distant from the zenith point by four times that quantity, i. e. by 52'' 41' 20'', a space which corresponds to the path which she will describe during the entire journey of the projectile. But, inasmuch as it is equally necessary to take into account the deviation which the rotary motion of the earth will impart to the shot, and as the shot cannot reach the moon until after a deviation equal to 16 radii of the earth, which, calculated upon the moon's orbit, are equal to about eleven degrees, it becomes necessary to add these eleven degrees to those which express the retardation of the moon just mentioned: that is to say, in round numbers, about sixty-four degrees. Consequently, at the moment of firing the visual radius applied to the moon will describe, with the vertical line of the place, an angle of sixty-four degrees.

These are our answers to the questions proposed to the Observatory of Cambridge by the members of the Gun Club:

To sum up--

1st. The cannon ought to be planted in a country situated between 0@ and 28@ of N. or S. lat.

2nd. It ought to be pointed directly toward the zenith of the place.

3rd. The projectile ought to be propelled with an initial velocity of 12,000 yards per second.

4th. It ought to be discharged at 10hrs. 46m. 40sec. of the 1st of December of the ensuing year.

5th. It will meet the moon four days after its discharge, precisely at midnight on the 4th of December, at the moment of its transit across the zenith.

The members of the Gun Club ought, therefore, without delay, to commence the works necessary for such an experiment, and to be prepared to set to work at the moment determined upon; for, if they should suffer this 4th of December to go by, they will not find the moon again under the same conditions of perigee and of zenith until eighteen years and eleven days afterward.

The staff of the Cambridge Observatory place themselves entirely at their disposal in respect of all questions of theoretical astronomy; and herewith add their congratulations to those of all the rest of America.
For the Astronomical Staff,
J. M. BELFAST,
Director of the Observatory of Cambridge.

FICTION: From the Earth to the Moon, Ch 3: EFFECT OF THE PRESIDENT'S COMMUNICATION

CHAPTER III --EFFECT OF THE PRESIDENT'S COMMUNICATION
It is impossible to describe the effect produced by the last words of the honorable president-- the cries, the shouts, the succession of roars, hurrahs, and all the varied vociferations which the American language is capable of supplying. It was a scene of indescribable confusion and uproar. They shouted, they clapped, they stamped on the floor of the hall. All the weapons in the museum discharged at once could not have more violently set in motion the waves of sound. One need not be surprised at this. There are some cannoneers nearly as noisy as their own guns.

Barbicane remained calm in the midst of this enthusiastic clamor; perhaps he was desirous of addressing a few more words to his colleagues, for by his gestures he demanded silence, and his powerful alarum was worn out by its violent reports. No attention, however, was paid to his request. He was presently torn from his seat and passed from the hands of his faithful colleagues into the arms of a no less excited crowd.

Nothing can astound an American. It has often been asserted that the word "impossible" in not a French one. People have evidently been deceived by the dictionary. In America, all is easy, all is simple; and as for mechanical difficulties, they are overcome before they arise. Between Barbicane's proposition and its realization no true Yankee would have allowed even the semblance of a difficulty to be possible. A thing with them is no sooner said than done.

The triumphal progress of the president continued throughout the evening. It was a regular torchlight procession. Irish, Germans, French, Scotch, all the heterogeneous units which make up the population of Maryland shouted in their respective vernaculars; and the "vivas," "hurrahs," and "bravos" were intermingled in inexpressible enthusiasm.

Just at this crisis, as though she comprehended all this agitation regarding herself, the moon shone forth with serene splendor, eclipsing by her intense illumination all the surrounding lights. The Yankees all turned their gaze toward her resplendent orb, kissed their hands, called her by all kinds of endearing names. Between eight o'clock and midnight one optician in Jones'-Fall Street made his fortune by the sale of opera-glasses.

Midnight arrived, and the enthusiasm showed no signs of diminution. It spread equally among all classes of citizens-- men of science, shopkeepers, merchants, porters, chair-men, as well as "greenhorns," were stirred in their innermost fibres. A national enterprise was at stake. The whole city, high and low, the quays bordering the Patapsco, the ships lying in the basins, disgorged a crowd drunk with joy, gin, and whisky. Every one chattered, argued, discussed, disputed, applauded, from the gentleman lounging upon the barroom settee with his tumbler of sherry-cobbler before him down to the waterman who got drunk upon his "knock-me-down" in the dingy taverns of Fell Point.

About two A.M., however, the excitement began to subside. President Barbicane reached his house, bruised, crushed, and squeezed almost to a mummy. Hercules could not have resisted a similar outbreak of enthusiasm. The crowd gradually deserted the squares and streets. The four railways from Philadelphia and Washington, Harrisburg and Wheeling, which converge at Baltimore, whirled away the heterogeneous population to the four corners of the United States, and the city subsided into comparative tranquility.

On the following day, thanks to the telegraphic wires, five hundred newspapers and journals, daily, weekly, monthly, or bi-monthly, all took up the question. They examined it under all its different aspects, physical, meteorological, economical, or moral, up to its bearings on politics or civilization. They debated whether the moon was a finished world, or whether it was destined to undergo any further transformation. Did it resemble the earth at the period when the latter was destitute as yet of an atmosphere? What kind of spectacle would its hidden hemisphere present to our terrestrial spheroid? Granting that the question at present was simply that of sending a projectile up to the moon, everyone must see that that involved the commencement of a series of experiments. All must hope that someday America would penetrate the deepest secrets of that mysterious orb; and some even seemed to fear lest its conquest should not sensibly derange the equilibrium of Europe.

The project once under discussion, not a single paragraph suggested a doubt of its realization. All the papers, pamphlets, reports--all the journals published by the scientific, literary, and religious societies enlarged upon its advantages; and the Society of Natural History of Boston, the Society of Science and Art of Albany, the Geographical and Statistical Society of New York, the Philosophical Society of Philadelphia, and the Smithsonian of Washington sent innumerable letters of congratulation to the Gun Club, together with offers of immediate assistance and money.

From that day forward Impey Barbicane became one of the greatest citizens of the United States, a kind of Washington of science. A single trait of feeling, taken from many others, will serve to show the point which this homage of a whole people to a single individual attained.

Some few days after this memorable meeting of the Gun Club, the manager of an English company announced, at the Baltimore theatre, the production of "Much ado about Nothing." But the populace, seeing in that title an allusion damaging to Barbicane's project, broke into the auditorium, smashed the benches, and compelled the unlucky director to alter his playbill. Being a sensible man, he bowed to the public will and replaced the offending comedy by "As you like it"; and for many weeks he realized fabulous profits.

From the Earth to the Moon Ch 2: PRESIDENT BARBICANE'S COMMUNICATION

CHAPTER II
PRESIDENT BARBICANE'S COMMUNICATION


On the 5th of October, at eight p.m., a dense crowd pressed toward the saloons of the Gun Club at No. 21 Union Square. All the members of the association resident in Baltimore attended the invitation of their president. As regards the corresponding members, notices were delivered by hundreds throughout the streets of the city, and, large as was the great hall, it was quite inadequate to accommodate the crowd of savants. They overflowed into the adjoining rooms, down the narrow passages, into the outer courtyards. There they ran against the vulgar herd who pressed up to the doors, each struggling to reach the front ranks, all eager to learn the nature of the important communication of President Barbicane; all pushing, squeezing, crushing with that perfect freedom of action which is so peculiar to the masses when educated in ideas of "self-government."

On that evening a stranger who might have chanced to be in Baltimore could not have gained admission for love or money into the great hall. That was reserved exclusively for resident or corresponding members; no one else could possibly have obtained a place; and the city magnates, municipal councilors, and "select men" were compelled to mingle with the mere townspeople in order to catch stray bits of news from the interior.

Nevertheless the vast hall presented a curious spectacle. Its immense area was singularly adapted to the purpose. Lofty pillars formed of cannon, superposed upon huge mortars as a base, supported the fine ironwork of the arches, a perfect piece of cast-iron lacework. Trophies of blunderbuses, matchlocks, arquebuses, carbines, all kinds of firearms, ancient and modern, were picturesquely interlaced against the walls. The gas lit up in full glare myriads of revolvers grouped in the form of lustres, while groups of pistols, and candelabra formed of muskets bound together, completed this magnificent display of brilliance. Models of cannon, bronze castings, sights covered with dents, plates battered by the shots of the Gun Club, assortments of rammers and sponges, chaplets of shells, wreaths of projectiles, garlands of howitzers-- in short, all the apparatus of the artillerist, enchanted the eye by this wonderful arrangement and induced a kind of belief that their real purpose was ornamental rather than deadly.

At the further end of the saloon the president, assisted by four secretaries, occupied a large platform. His chair, supported by a carved gun-carriage, was modeled upon the ponderous proportions of a 32-inch mortar. It was pointed at an angle of ninety degrees, and suspended upon truncheons, so that the president could balance himself upon it as upon a rocking-chair, a very agreeable fact in the very hot weather. Upon the table (a huge iron plate supported upon six carronades) stood an inkstand of exquisite elegance, made of a beautifully chased Spanish piece, and a sonnette, which, when required, could give forth a report equal to that of a revolver. During violent debates this novel kind of bell scarcely sufficed to drown the clamor of these excitable artillerists.

In front of the table benches arranged in zigzag form, like the circumvallations of a retrenchment, formed a succession of bastions and curtains set apart for the use of the members of the club; and on this especial evening one might say, "All the world was on the ramparts." The president was sufficiently well known, however, for all to be assured that he would not put his colleagues to discomfort without some very strong motive.

Impey Barbicane was a man of forty years of age, calm, cold, austere; of a singularly serious and self-contained demeanor, punctual as a chronometer, of imperturbable temper and immovable character; by no means chivalrous, yet adventurous withal, and always bringing practical ideas to bear upon the very rashest enterprises; an essentially New Englander, a Northern colonist, a descendant of the old anti-Stuart Roundheads, and the implacable enemy of the gentlemen of the South, those ancient cavaliers of the mother country. In a word, he was a Yankee to the backbone.

Barbicane had made a large fortune as a timber merchant. Being nominated director of artillery during the war, he proved himself fertile in invention. Bold in his conceptions, he contributed powerfully to the progress of that arm and gave an immense impetus to experimental researches.

He was personage of the middle height, having, by a rare exception in the Gun Club, all his limbs complete. His strongly marked features seemed drawn by square and rule; and if it be true that, in order to judge a man's character one must look at his profile, Barbicane, so examined, exhibited the most certain indications of energy, audacity, and sang-froid.

At this moment he was sitting in his armchair, silent, absorbed, lost in reflection, sheltered under his high-crowned hat-- a kind of black cylinder which always seems firmly screwed upon the head of an American.

Just when the deep-toned clock in the great hall struck eight, Barbicane, as if he had been set in motion by a spring, raised himself up. A profound silence ensued, and the speaker, in a somewhat emphatic tone of voice, commenced as follows:

"My brave, colleagues, too long already a paralyzing peace has plunged the members of the Gun Club in deplorable inactivity. After a period of years full of incidents we have been compelled to abandon our labors, and to stop short on the road of progress. I do not hesitate to state, baldly, that any war which would recall us to arms would be welcome!" (Tremendous applause!) "But war, gentlemen, is impossible under existing circumstances; and, however we may desire it, many years may elapse before our cannon shall again thunder in the field of battle. We must make up our minds, then, to seek in another train of ideas some field for the activity which we all pine for."

The meeting felt that the president was now approaching the critical point, and redoubled their attention accordingly.

"For some months past, my brave colleagues," continued Barbicane, "I have been asking myself whether, while confining ourselves to our own particular objects, we could not enter upon some grand experiment worthy of the nineteenth century; and whether the progress of artillery science would not enable us to carry it out to a successful issue. I have been considering, working, calculating; and the result of my studies is the conviction that we are safe to succeed in an enterprise which to any other country would appear wholly impracticable. This project, the result of long elaboration, is the object of my present communication. It is worthy of yourselves, worthy of the antecedents of the Gun Club; and it cannot fail to make some noise in the world."

A thrill of excitement ran through the meeting.

Barbicane, having by a rapid movement firmly fixed his hat upon his head, calmly continued his harangue:

"There is no one among you, my brave colleagues, who has not seen the Moon, or, at least, heard speak of it. Don't be surprised if I am about to discourse to you regarding the Queen of the Night. It is perhaps reserved for us to become the Columbuses of this unknown world. Only enter into my plans, and second me with all your power, and I will lead you to its conquest, and its name shall be added to those of the thirty-six states which compose this Great Union."

"Three cheers for the Moon!" roared the Gun Club, with one voice.

"The moon, gentlemen, has been carefully studied," continued Barbicane; "her mass, density, and weight; her constitution, motions, distance, as well as her place in the solar system, have all been exactly determined. Selenographic charts have been constructed with a perfection which equals, if it does not even surpass, that of our terrestrial maps. Photography has given us proofs of the incomparable beauty of our satellite; all is known regarding the moon which mathematical science, astronomy, geology, and optics can learn about her. But up to the present moment no direct communication has been established with her."

A violent movement of interest and surprise here greeted this remark of the speaker.

"Permit me," he continued, "to recount to you briefly how certain ardent spirits, starting on imaginary journeys, have penetrated the secrets of our satellite. In the seventeenth century a certain David Fabricius boasted of having seen with his own eyes the inhabitants of the moon. In 1649 a Frenchman, one Jean Baudoin, published a Journey performed from the Earth to the Moon by Domingo Gonzalez, a Spanish adventurer.

At thesame period Cyrano de Bergerac published that celebrated Journeys in the Moon which met with such success in France. Somewhat later another Frenchman, named Fontenelle, wrote The Plurality of Worlds, a chef-d'oeuvre of its time. About 1835 a small treatise, translated from the New York American, related how Sir John Herschel, having been despatched to the Cape of Good Hope for the purpose of making there some astronomical calculations, had, by means of a telescope brought to perfection by means of internal lighting, reduced the apparent distance of the moon to eighty yards! He then distinctly perceived caverns frequented by hippopotami, green mountains bordered by golden lace-work, sheep with horns of ivory, a white species of deer and inhabitants with membranous wings, like bats.

This brochure, the work of an American named Locke, had a great sale. But, to bring this rapid sketch to a close, I will only add that a certain Hans Pfaal, of Rotterdam, launching himself in a balloon filled with a gas extracted from nitrogen, thirty-seven times lighter than hydrogen, reached the moon after a passage of nineteen hours. This journey, like all previous ones, was purely imaginary; still, it was the work of a popular American author-- I mean Edgar Poe!"

"Cheers for Edgar Poe!" roared the assemblage, electrified by their president's words.

"I have now enumerated," said Barbicane, "the experiments which I call purely paper ones, and wholly insufficient to establish serious relations with the Queen of the Night. Nevertheless, I am bound to add that some practical geniuses have attempted to establish actual communication with her.

Thus, a few days ago, a German geometrician proposed to send a scientific expedition
to the steppes of Siberia. There, on those vast plains, they were to describe enormous geometric figures, drawn in characters of reflecting luminosity, among which was the proposition regarding the `square of the hypothenuse,' commonly called the `Ass's Bridge' by the French. `Every intelligent being,' said the geometrician, `must understand the scientific meaning of that figure. The Selenites, do they exist, will respond by a similar figure; and, a communication being thus once established, it will be easy to form an alphabet which shall enable us to converse with the inhabitants of the moon.'

So spoke the German geometrician; but his project was never put into practice, and up to the present day there is no bond in existence between the Earth and her satellite. It is reserved for the practical genius of Americans to establish a communication with the sidereal world. The means of arriving thither are simple, easy, certain, infallible-- and that is the purpose of my present proposal."

A storm of acclamations greeted these words. There was not asingle person in the whole audience who was not overcome, carried away, lifted out of himself by the speaker's words!

Long-continued applause resounded from all sides.

As soon as the excitement had partially subsided, Barbicane resumed his speech in a somewhat graver voice.

"You know," said he, "what progress artillery science has made during the last few years, and what a degree of perfection firearms of every kind have reached. Moreover, you are well aware that, in general terms, the resisting power of cannon and the expansive force of gunpowder are practically unlimited. Well! starting from this principle, I ask myself whether, supposing sufficient apparatus could be obtained constructed upon the conditions of ascertained resistance, it might not be possible to project a shot up to the moon?"

At these words a murmur of amazement escaped from a thousand panting chests; then succeeded a moment of perfect silence, resembling that profound stillness which precedes the bursting of a thunderstorm. In point of fact, a thunderstorm did peal forth, but it was the thunder of applause, or cries, and of uproar which made the very hall tremble. The president attempted to speak, but could not. It was fully ten minutes before he could make himself heard.

"Suffer me to finish," he calmly continued. "I have looked at the question in all its bearings, I have resolutely attacked it, and by incontrovertible calculations I find that a projectile endowed with an initial velocity of 12,000 yards per second, and aimed at the moon, must necessarily reach it. I have the honor, my brave colleagues, to propose a trial of this little experiment."
