The Man Who Rocked the Earth Part 9

He hung the plate by two fine wires fastened to its corners, and adjusted a coil of wire opposite its centre, while within the coil he slipped a small black capsule.

"This is the best we can do now," he said. "The capsule is made of zircorundum, and we shall get only a trace of the disintegrating rays before it blows up. But you'll see 'em, or, rather, you'll see the lavender phosph.o.r.escence of the air through which they pa.s.s."

He arranged a thick slab of plate gla.s.s between Thornton and the thermic transformer, and stepping to the wall closed a switch. An oscillatory spark discharge started off with a roar in a closed box, and the coil of wire became white hot.

"Watch the plate!" shouted Bennie.

And Thornton watched.

For ten or fifteen seconds nothing happened, and then a faint beam of pale lavender light shot out from the capsule, and the metal plate swung away from the incandescent coil as if blown by a gentle breeze.

Almost instantly there was a loud report and a blinding flash of yellow light so brilliant that for the next instant or two to Thornton's eyes the room seemed dark. Slowly the afternoon light regained its normal quality. Bennie relit his pipe unconcernedly.

"That's the germ of the idea," he said between puffs. "That capsule contains a mixture of vapours that give out disintegrating rays when the temperature is raised by thermic induction above six thousand. Most of 'em are stopped by the zirconium atoms in the capsule, which break down and liberate helium; and the temperature rises in the capsule until it explodes, as you saw just now, with a flash of yellow helium light. The rays that get out strike the uranium plate and cause the surface layer of molecules to disintegrate, their products being driven off by the atomic explosions with a velocity about equal to that of light, and it's the recoil that deflects and swings the plate. The amount of uranium decomposed in this experiment couldn't be detected by the most delicate balance--small ma.s.s, but enormous velocity. See?"

"Yes, I understand," answered Thornton. "It's the old, 'momentum equals ma.s.s times velocity,' business we had in mechanics."

"Of course this is only a toy experiment," Bennie continued. "It is what the dancing pithb.a.l.l.s of Franklin's time were to the multipolar, high-frequency dynamo. But if we could control this force and handle it on a large scale we could do anything with it--destroy the world, drive a car against gravity off into s.p.a.ce, shift the axis of the earth perhaps!"

It came to Thornton as he sat there, cigarette in hand, that poor Bennie Hooker was going to receive the disappointment of his life. Within the next five minutes his dreams would be dashed to earth, for he would learn that another had stepped down to the pool of discovery before him.

For how many years, he wondered, had Bennie toiled to produce his mysterious ray that should break down the atom and release the store of energy that the genii of Nature had concealed there. And now Thornton must tell him that all his efforts had gone for nothing!

"And you believe that any one who could generate a ray such as you describe could control the motion of the earth?" he asked.

"Of course, certainly," answered Hooker. "He could either disintegrate such huge quant.i.ties of matter that the ma.s.s of the earth would be shifted and its polar axis be changed, or if radioactive substances--pitchblende, for example--lay exposed upon the earth's surface he could cause them to discharge their helium and other products at such an enormous velocity that the recoil or reaction would accelerate or r.e.t.a.r.d the motion of the globe. It would be quite feasible, quite simple--all one would need would be the disintegrating ray."

And then Thornton told Hooker of the flight of the giant Ring machine from the north and the destruction of the Mountains of Atlas through the apparent instrumentality of a ray of lavender light. Hooker's face turned slightly pale and his unshaven mouth tightened. Then a smile of exaltation illuminated his features.

"He's done it!" he cried joyously. "He's done it on an engineering scale. We pure-science dreamers turn up our noses at the engineers, but I tell you the improvements in the apparatus part of the game come when there is a big commercial demand for a thing and the engineering chaps take hold of it. But _who_ is he and _where_ is he? I must get to him. I don't suppose I can teach him much, but I've got a magnificent experiment that we can try together."

He turned to a littered writing-table and poked among the papers that lay there.

"You see," he explained excitedly, "if there is anything in the quantum theory----Oh! but you don't care about that. The point is where _is_ the chap?"

And so Thornton had to begin at the beginning and tell Hooker all about the mysterious messages and the phenomena that accompanied them. He enlarged upon Pax's benignant intentions and the great problems presented by the proposed interference of the United States Government in Continental affairs, but Bennie swept them aside. The great thing, to his mind, was to find and get into communication with Pax.

"Ah! How he must feel! The greatest achievement of all time!" cried Hooker radiantly. "How ecstatically happy! Earth blossoming like the rose! Well-watered valleys where deserts were before. War abolished, poverty, disease! Who can it be? Curie? No; she's bottled in Paris.

Posky, Langham, Varanelli--it can't be any one of those fellows. It beats me! Some Hindoo or j.a.p maybe, but never Hiros.h.i.to! Now we must get to him right away. So much to talk over." He walked round the room, blundering into things, dizzy with the thought that his great dream had come true. Suddenly he swept everything off the table on to the floor and kicked his heels in the air.

"Hooray!" he shouted, dancing round the room like a freshman. "Hooray!

Now I can take a holiday. And come to think of it, I'm as hungry as a brontosaurus!"

That night Thornton returned to Washington and was at the White House by nine o'clock the following day.

"It's all straight," he told the President. "The honestest man in the United States has said so."

XI

The moon rose over sleeping Paris, silvering the silent reaches of the Seine, flooding the deserted streets with mellow light, yet gently retouching all the disfigurements of the siege. No lights illuminated the cafes, no taxis dashed along the boulevards, no crowds loitered in the Place de l'Opera or the Place Vendome. Yet save for these facts it might have been the Paris of old time, unvisited by hunger, misery, or death. The curfew had sounded. Every citizen had long since gone within, extinguished his lights, and locked his door. Safe in the knowledge that the Germans' second advance had been finally met and effectually blocked sixty miles outside the walls, and that an armistice had been declared to go into effect at midnight, Paris slumbered peacefully.

Beyond the pellet-strewn fields and glacis of the second line of defence the invader, after a series of terrific onslaughts, had paused, retreated a few miles and intrenched himself, there to wait until the starving city should capitulate. For four months he had waited, yet Paris gave no sign of surrendering. On the contrary, it seemed to have some mysterious means of self-support, and the war office, in daily communication with London, reported that it could withstand the investment for an indefinite period. Meantime the Germans reintrenched themselves, built forts of their own upon which they mounted the siege guns intended for the walls, and constructed an impregnable line of entanglements, redoubts, and defences, which rendered it impossible for any army outside the city to come to its relief.

So rose the moon, turning white the millions of slate roofs, gilding the traceries of the towers of Notre Dame, dimming the searchlights which, like the antennae of gigantic fireflies, constantly played round the city from the summit of the Eiffel Tower. So slept Paris, confident that no crash of descending bombs would shatter the blue vault of the starlit sky or rend the habitations in which lay two millions of human beings, a.s.sured that the sun would rise through the gray mists of the Seine upon the ancient beauties of the Tuilleries and the Louvre unmarred by the enemy's projectiles, and that its citizens could pa.s.s freely along its boulevards without menace of death from flying missiles. For no sh.e.l.l could be hurled a distance of sixty miles, and an armistice had been declared.

Behind a small hill within the German fortifications a group of officers stood in the moonlight, examining what looked superficially like the hangar of a small dirigible. Nestling behind the hill it cast a black rectangular shadow upon the trampled sand of the redoubt. A score of artisans were busy filling a deep trench through which a huge pipe led off somewhere--a sort of deadly plumbing, for the house sheltered a monster cannon reenforced by jackets of lead and steel, the whole encased in a cooling apparatus of intricate manufacture. From the open end of the house the cylindrical barrel of the gigantic engine of war raised itself into the air at an angle of forty degrees, and from the muzzle to the ground below it was a drop of over eighty feet. On a track running off to the north rested the projectiles side by side, resembling in the dim light a row of steam boilers in the yard of a locomotive factory.

"Well," remarked one of the officers, turning to the only one of his companions not in uniform. "'Thanatos' is ready."

The man addressed was Von Heckmann, the most famous inventor of military ordnance in the world, already four times decorated for his services to the Emperor.

"The labour of nine years!" he answered with emotion. "Nine long years of self-denial and unremitting study! But to-night I shall be repaid, repaid a thousand times."

The officers shook hands with him one after the other, and the group broke up; the men who were filling the trench completed their labours and departed; and Von Heckmann and the major-general of artillery alone remained, except for the sentries beside the gun. The night was balmy and the moon rode in a cloudless sky high above the hill. They crossed the enclosure, followed by the two sentinels, and entering a pa.s.sage reached the outer wall of the redoubt, which was in turn closed and locked. Here the sentries remained, but Von Heckmann and the general continued on behind the fortifications for some distance.

"Well, shall we start the ball?" asked the general, laying his hand on Von Heckmann's shoulder. But the inventor found it so hard to master his emotion that he could only nod his head. Yet the ball to which the general alluded was the discharging of a fiendish war machine toward an unsuspecting and harmless city alive with sleeping people, and the emotion of the inventor was due to the fact that he had devised and completed the most atrocious engine of death ever conceived by the mind of man--the Relay Gun. Horrible as is the thought, this otherwise normal man had devoted nine whole years to the problem of how to destroy human life at a distance of a hundred kilometres, and at last he had been successful, and an emperor had placed with his own divinely appointed hands a ribbon over the spot beneath which his heart should have been.

The projectile of this diabolical invention was ninety-five centimetres in diameter, and was itself a rifled mortar, which in full flight, twenty miles from the gun and at the top of its trajectory, exploded in mid-air, hurling forward its contained projectile with an additional velocity of three thousand feet per second. This process repeated itself, the final or core bomb, weighing over three hundred pounds and filled with lyddite, reaching its mark one minute and thirty-five seconds after the firing of the gun. This crowning example of the human mind's destructive ingenuity had cost the German Government five million marks and had required three years for its construction, and by no means the least of its devilish capacities was that of automatically reloading and firing itself at the interval of every ten seconds, its muzzle rising, falling, or veering slightly from side to side with each discharge, thus causing the sh.e.l.ls to fall at wide distances. The poisonous nature of the immense volumes of gas poured out by the mastodon when in action necessitated the withdrawal of its crew to a safe distance. But once set in motion it needed no attendant. It had been tested by a preliminary shot the day before, which had been directed to a point several miles outside the walls of Paris, the effect of which had been observed and reported by high-flying German aeroplanes equipped with wireless. Everything was ready for the holocaust.

Von Heckmann and the general of artillery continued to make their way through the intrenchments and other fortifications, until at a distance of about a quarter of a mile from the redoubt where they had left the Relay Gun they arrived at a small whitewashed cottage.

"I have invited a few of my staff to join us," said the general to the inventor, "in order that they may in years to come describe to their children and their grandchildren this, the most momentous occasion in the history of warfare."

They turned the corner of the cottage and came upon a group of officers standing by the wooden gate of the cottage, all of whom saluted at their approach.

"Good evening, gentlemen," said the general. "I beg to present the members of my staff," turning to Von Heckmann.

The officers stood back while the general led the way into the cottage, the lower floor of which consisted of but a single room, used by the recent tenants as a kitchen, dining-room, and living-room. At one end of a long table, constructed by the regimental carpenter, supper had been laid, and a tub filled with ice contained a dozen or more quarts of champagne. Two orderlies stood behind the table, at the other end of which was affixed a small bra.s.s switch connected with the redoubt and controlled by a spring and b.u.t.ton. The windows of the cottage were open, and through them poured the light of the full moon, dimming the flickering light of the candles upon the table.

In spite of the champagne, the supper, and the boxes of cigars and cigarettes, an atmosphere of solemnity was distinctly perceptible. It was as if each one of these officers, hardened to human suffering by a lifetime of discipline and active service, to say nothing of the years of horror through which they had just pa.s.sed, could not but feel that in the last a.n.a.lysis the hurling upon an unsuspecting city of a rain of projectiles containing the highest explosive known to warfare, at a distance three times greater than that heretofore supposed to be possible to science, and the ensuing annihilation of its inhabitants, was something less for congratulation and applause than for sorrow and regret. The officers, who had joked each other outside the gate, became singularly quiet as they entered the cottage and gathered round the table where Von Heckmann and the general had taken their stand by the instrument. Utter silence fell upon the group. The mercury of their spirits dropped from summer heat to below freezing. What was this thing which they were about to do?

Through the windows, at a distance of four hundred yards, the pounding of the machinery which flooded the water jacket of the Relay Gun was distinctly audible in the stillness of the night. The pressure of a finger--a little finger--upon that electric b.u.t.ton was all that was necessary to start the torrent of iron and high explosives toward Paris.

By the time the first sh.e.l.l would reach its mark nine more would be on their way, stretched across the midnight sky at intervals of less than eight miles. And once started the stream would continue uninterrupted for two hours. The fascinated eyes of all the officers fastened themselves upon the key. None spoke.

"Well, well, gentlemen!" exclaimed the general brusquely, "what is the matter with you? You act as if you were at a funeral! Hans," turning to the orderly, "open the champagne there. Fill the gla.s.ses. b.u.mpers all, gentlemen, for the greatest inventor of all times, Herr von Heckmann, the inventor of the Relay Gun!"

The orderly sprang forward and hastily commenced uncorking bottles, while Von Heckmann turned away to the window.

"Here, this won't do, Sch.e.l.ling! You must liven things up a bit!"

continued the general to one of the officers. "This is a great occasion for all of us! Give me that bottle." He seized a magnum of champagne from the orderly and commenced pouring out the foaming liquid into the gla.s.ses beside the plates. Sch.e.l.ling made a feeble attempt at a joke at which the officers laughed loudly, for the general was a martinet and had to be humoured.

"Now, then," called out the general as he glanced toward the window, "Herr von Heckmann, we are going to drink your health! Officers of the First Artillery, I give you a toast--a toast which you will all remember to your dying day! b.u.mpers, gentlemen! No heel taps! I give you the health of 'Thanatos'--the leviathan of artillery, the winged bearer of death and destruction--and of its inventor, Herr von Heckmann. b.u.mpers, gentlemen!" The general slapped Von Heckmann upon the shoulder and drained his gla.s.s.

"'Thanatos!' Von Heckmann!" shouted the officers. And with one accord they dashed their goblets to the stone flagging upon which they stood.
