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!
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
