Chapter 10

________________________________________________
_ CHAPTER X

All day the International Assembly of Scientists, officially known as Conference No. 2, had been sitting, but not progressing, in the large lecture hall of the Smithsonian Institution, which probably had never before seen so motley a gathering. Each nation had sent three representatives, two professional scientists, and a lay delegate, the latter some writer or thinker renowned in his own country for his wide knowledge and powers of ratiocination. They had come together upon the appointed day, although the delegates from the remoter countries had not yet arrived, and the Committee on Credentials had already reported. Germany had sent Gasgabelaus, Leybach, and Wilhelm Lamszus; France--Sortell, Amand, and Buona Varilla; Great Britain--Sir William Crookes, Sir Francis Soddy, and Mr. H. G. Wells, celebrated for his "The War of the Worlds" and The "World Set Free," and hence supposedly just the man to unravel a scientific mystery such as that which confronted this galaxy of immortals.

The Committee on Data, of which Thornton was a member, having been actively at work for nearly two weeks through wireless communication with all the observatories--seismic, meteorological, astronomical, and otherwise--throughout the world, had reduced its findings to print, and this matter, translated into French, German, and Italian, had already been distributed among those present. Included in its pages was Quinn's letter to the State Department.

The roll having been called, the president of the National Academy of Sciences made a short speech in which he outlined briefly the purpose for which the committee had been summoned and commented to some extent upon the character of the phenomena it was required to analyze.

And then began an unending series of discussions and explanations in French, German, Dutch, Russian, and Italian, by goggle-eyed, bushy-whiskered, long-haired men who looked like anarchists or sociologists and apparently had never before had an unrestricted opportunity to air their views on anything.

Thornton, listening to this hodgepodge of technicalities, was dismayed and distrustful. These men spoke a language evidently familiar to them, which he, although a professional scientist, found a meaningless jargon. The whole thing seemed unreal, had a purely theoretic or literary quality about it that made him question even their premises. In the tainted air of the council room, listening to these little pot-bellied Professoren from Amsterdam and Muenich, doubt assailed him, doubt even that the earth had changed its orbit, doubt even of his own established formulae and tables. Weren't they all just talking through their hats? Wasn't it merely a game in which an elaborate system of equivalents gave a semblance of actuality to what in fact was nothing but mind-play? Even Wells, whose literary style he admired as one of the beauties as well as one of the wonders of the world, had been a disappointment. He had seemed singularly halting and unconvincing.

"I wish I knew a practical man--I wish Bennie Hooker were here!" muttered Thornton to himself. He had not seen his classmate Hooker for twenty-six years; but that was one thing about Hooker: you knew he'd be exactly the same--only more so--as he was when you last saw him. In those years Bennie had become the Lawson Professor of Applied Physics at Harvard. Thornton had read his papers on induced radiation, thermic equilibrium, and had one of Bennie's famous Gem Home Cookers in his own little bachelor apartment. Hooker would know. And if he didn't he'd tell you so, without befogging the atmosphere with a lot of things he did know, but that wouldn't help you in the least. Thornton clutched at the thought of him like a falling aeronaut at a dangling rope. He'd be worth a thousand of these dreaming lecturers, these beer-drinking visionaries! But where could he be found? It was August, vacation time. Still, he might be in Cambridge giving a summer course or something.

At that moment Professor Gasgabelaus, the temporary chairman, a huge man, the periphery of whose abdomen rivalled the circumference of the "working terrestrial globe" at the other end of the platform, pounded perspiringly with his gavel and announced that the conference would adjourn until the following Monday morning. It was Friday afternoon, so he had sixty hours in which to connect with Bennie, if Bennie could be discovered. A telegram of inquiry brought no response, and he took the midnight train to Boston, reaching Cambridge about two o'clock the following afternoon.

The air trembled with heat. Only by dodging from the shadow of one big elm to another did he manage to reach the Appian Way--the street given in the university catalogue as Bennie's habitat--alive. As he swung open the little wicket gate he realized with an odd feeling that it was the same house where Hooker had lived when a student, twenty-five years before.

"Board" was printed on a yellow, fly-blown card in the corner of the window beside the door.

Up there over the porch was the room Bennie had inhabited from '85 to '89. He recalled vividly the night he, Thornton, had put his foot through the lower pane. They had filled up the hole with an old golf stocking. His eyes searched curiously for the pane. There it was, still broken and still stuffed--it couldn't be!--with some colourless material strangely resembling disintegrating worsted. The sun smote him in the back of his neck and drove him to seek the relief of the porch. Had he ever left Cambridge? Wasn't it a dream about his becoming an astronomer and working at the Naval Observatory? And all this stuff about the earth going on the loose? If he opened the door wouldn't he find Bennie with a towel round his head cramming for the "exams"? For a moment he really imagined that he was an undergraduate. Then as he fanned himself with his straw hat he caught, on the silk band across the interior, the words: "Smith's Famous Headwear, Washington, D.C." No, he was really an astronomer.

He shuddered in spite of the heat as he pulled the bell knob. What ghosts would its jangle summon? The bell, however, gave no sound; in fact the knob came off in his hand, followed by a foot or so of copper wire. He laughed, gazing at it blankly. No one had ever used the bell in the old days. They had simply kicked open the door and halloed: "O-o-h, Bennie Hooker!"

Thornton laid the knob on the piazza and inspected the front of the house. The windows were thick with dust, the "yard" scraggly with weeds. A piece of string held the latch of the gate together. Then automatically, and without intending to do so at all, Thornton turned the handle of the front door, assisting it coincidentally with a gentle kick from his right toe, and found himself in the narrow cabbage-scented hallway. The old, familiar, battered black-walnut hatrack of his student days leaned drunkenly against the wall--Thornton knew one of its back legs was missing--and on the imitation marble slab was a telegram addressed to "Professor Benjamin Hooker." And also, instinctively, Thornton lifted up his adult voice and yelled:

"O-o-h, ye-ay! Bennie Hooker!"

The volume of his own sound startled him. Instantly he saw the ridiculousness of it--he, the senior astronomer at the Naval Observatory, yelling like that----

"O-o-h, ye-ay!" came in smothered tones from above.

Thornton bounded up the stairs, two, three steps at a time, and pounded on the old door over the porch.

"Go away!" came back the voice of Bennie Hooker. "Don't want any lunch!"

Thornton continued to bang on the door while Professor Hooker wrathfully besought the intruder to depart before he took active measures. There was the cracking of glass.

"Oh, damn!" came from inside.

Thornton rattled the knob and kicked. Somebody haltingly crossed the room, the key turned, and Prof. Bennie Hooker opened the door.

"Well?" he demanded, scowling over his thick spectacles.

"Hello, Bennie!" said Thornton, holding out his hand.

"Hello, Buck!" returned Hooker. "Come in. I thought it was that confounded Ethiopian."

As far as Thornton could see, it was the same old room, only now crammed with books and pamphlets and crowded with tables of instruments. Hooker, clad in sneakers, white ducks, and an undershirt, was smoking a small "T. D." pipe.

"Where on earth did you come from?" he inquired good-naturedly.

"Washington," answered Thornton, and something told him that this was the real thing--the "goods"--that his journey would be repaid.

Hooker waved the "T. D." in a general sort of way toward some broken-down horsehair armchairs and an empty crate.

"Sit down, won't you?" he said, as if he had seen his guest only the day before. He looked vaguely about for something that Thornton might smoke, then seated himself on a cluttered bench holding a number of retorts, beside which flamed an oxyacetylene blowpipe. He was a wizened little chap, with scrawny neck and protruding Adam's apple. His long hair gave no evidence of the use of the comb, and his hands were the hands of Esau. He had an alertness that suggested a robin, but at the same time gave the impression that he looked through things rather than at them. On the mantel was a saucer containing the fast oxidizing cores of several apples and a half-eaten box of oatmeal biscuits.

"My Lord! This is an untidy hole! No more order than when you were an undergrad!" exclaimed Thornton, looking about him in amused horror.

"Order?" returned Bennie indignantly. "Everything's in perfect order! This chair is filled with the letters I have already answered; this chair with the letters I've not answered; and this chair with the letters I shall never answer!"

Thornton took a seat on the crate, laughing. It was the same old Bennie!

"You're an incorrigible!" he sighed despairingly.

"Well, you're a star gazer, aren't you?" inquired Hooker, relighting his pipe. "Some one told me so--I forget who. You must have a lot of interesting problems. They tell me that new planet of yours is full of uranium."

Thornton laughed. "You mustn't believe all that you read in the papers. What are you working at particularly?"

"Oh, radium and thermic induction mostly," answered Hooker. "And when I want a rest I take a crack at the fourth dimension--spacial curvature's my hobby. But I'm always working at radio stuff. That's where the big things are going to be pulled off, you know."

"Yes, of course," answered Thornton. He wondered if Hooker ever saw a paper, how long since he had been out of the house. "By the way, did you know Berlin had been taken?" he asked.

"Berlin--in Germany, you mean?"

"Yes, by the Russians."

"No! Has it?" inquired Hooker with politeness. "Oh, I think some one did mention it."

Thornton fumbled for a cigarette and Bennie handed him a match. They seemed to have extraordinarily little to say for men who hadn't seen each other for twenty-six years.

"I suppose," went on the astronomer, "you think it's deuced funny my dropping in casually this way after all this time, but the fact is I came on purpose. I want to get some information from you straight."

"Go ahead!" said Bennie. "What's it about?"

"Well, in a word," answered Thornton, "the earth's nearly a quarter of an hour behind time."

Hooker received this announcement with a polite interest but no astonishment.

"That's a how-de-do!" he remarked. "What's done it?"

"That's what I want you to tell me," said Thornton sternly. "What could do it?"

Hooker unlaced his legs and strolled over to the mantel.

"Have a cracker?" he asked, helping himself. Then he picked up a piece of wood and began whittling. "I suppose there's the devil to pay?" he suggested. "Things upset and so on? Atmospheric changes? When did it happen?"

"About three weeks ago. Then there's this Sahara business."

"What Sahara business?"

"Haven't you heard?"

"No," answered Hooker rather impatiently. "I haven't heard anything. I haven't any time to read the papers; I'm too busy. My thermic inductor transformers melted last week and I'm all in the air. What was it?"

"Oh, never mind now," said Thornton hurriedly, perceiving that Hooker's ignorance was an added asset. He'd get his science pure, uncontaminated by disturbing questions of fact. "How about the earth's losing that quarter of an hour?"

"Of course she's off her orbit," remarked Hooker in a detached way. "And you want to know what's done it? Don't blame you. I suppose you've gone into the possibilities of stellar attraction."

"Discount that!" ordered Thornton. "What I want to know is whether it could happen from the inside?"

"Why not?" inquired Hooker. "A general shift in the mass would do it. So would the mere application of force at the proper point."

"It never happened before."

"Of course not. Neither had seedless oranges until Burbank came along," said Hooker.

"Do you regard it as possible by any human agency?" inquired Thornton.

"Why not?" repeated Hooker. "All you need is the energy. And it's lying all round if you could only get at it. That's just what I'm working at now. Radium, uranium, thorium, actinium--all the radioactive elements--are, as everybody knows, continually disintegrating, discharging the enormous energy that is imprisoned in their molecules. It may take generations, epochs, centuries, for them to get rid of it and transform themselves into other substances, but they will inevitably do so eventually. They're doing with more or less of a rush what all the elements are doing at their leisure. A single ounce of uranium contains about the same amount of energy that could be produced by the combustion of ten tons of coal--but it won't let the energy go. Instead it holds on to it, and the energy leaks slowly, almost imperceptibly, away, like water from a big reservoir tapped only by a tiny pipe. 'Atomic energy' Rutherford calls it. Every element, every substance, has its ready to be touched off and put to use. The chap who can find out how to release that energy all at once will revolutionize the civilized world. It will be like the discovery that water could be turned into steam and made to work for us--multiplied a million times. If, instead of that energy just oozing away and the uranium disintegrating infinitesimally each year, it could be exploded at a given moment you could drive an ocean liner with a handful of it. You could make the old globe stagger round and turn upside down! Mankind could just lay off and take a holiday. But how?"

Bennie enthusiastically waved his pipe at Thornton.

"How! That's the question. Everybody's known about the possibilities, for Soddy wrote a book about it; but nobody's ever suggested where the key could be found to unlock that treasure-house of energy. Some chap made up a novel once and pretended it was done, but he didn't say how. But"--and he lowered his voice passionately--"I'm working at it, and--and--I've nearly--nearly got it."

Thornton, infected by his friend's excitement, leaned forward in his chair.

"Yes--nearly. If only my transformers hadn't melted! You see I got the idea from Savaroff, who noticed that the activity of radium and other elements wasn't constant, but varied with the degree of solar activity, reaching its maximum at the periods when the sun spots were most numerous. In other words, he's shown that the breakdown of the atoms of radium and the other radioactive elements isn't spontaneous, as Soddy and others had thought, but is due to the action of certain extremely penetrating rays given out by the sun. These particular rays are the result of the enormous temperature of the solar atmosphere, and their effect upon radioactive substances is analogous to that of the detonating cap upon dynamite. No one has been able to produce these rays in the laboratory, although Hempel has suspected sometimes that traces of them appeared in the radiations from powerful electric sparks. Everything came to a halt until Hiroshito discovered thermic induction, and we were able to elevate temperature almost indefinitely through a process similar to the induction of high electric potentials by means of transformers and the Ruhmkorff coil.

"Hiroshito wasn't looking for a detonating ray and didn't have time to bother with it, but I started a series of experiments with that end in view. I got close--I am close, but the trouble has been to control the forces set in motion, for the rapid rise in temperature has always destroyed the apparatus."

Thornton whistled. "And when you succeed?" he asked in a whisper.

Hooker's face was transfigured.

"When I succeed I shall control the world," he cried, and his voice trembled. "But the damn thing either melts or explodes," he added with a tinge of indignation.

"You know about Hiroshito's experiments, of course; he used a quartz bulb containing a mixture of neon gas and the vapour of mercury, placed at the centre of a coil of silver wire carrying a big oscillatory current. This induced a ring discharge in the bulb, and the temperature of the vapour mixture rose until the bulb melted. He calculated that the temperature of that part of the vapour which carried the current was over 6,000 deg.. You see, the ring discharge is not in contact with the wall of the bulb, and can consequently be much hotter. It's like this." Here Bennie drew with a burnt match on the back of an envelope a diagram of something which resembled a doughnut in a chianti flask.

Thornton scratched his head. "Yes," he said, "but that's an old principle, isn't it? Why does Hiro--what's his name--call it--thermic induction?"

"Oriental imagination, probably," replied Bennie. "Hiroshito observed that a sudden increase in the temperature of the discharge occurred at the moment when the silver coil of his transformer became white hot, which he explained by some mysterious inductive action of the heat vibrations. I don't follow him at all. His theory's probably all wrong, but he delivered the goods. He gave me the right tip, even if I have got him lashed to the mast now. I use a tungsten spiral in a nitrogen atmosphere in my transformer and replace the quartz bulb with a capsule of zircorundum."

"A capsule of what?" asked Thornton, whose chemistry was mid-Victorian.

"Zircorundum," said Bennie, groping around in a drawer of his work table. "It's an absolute nonconductor of heat. Look here, just stick your finger in that." He held out to Thornton what appeared to be a small test tube of black glass. Thornton, with a slight moral hesitation, did as he was told, and Bennie, whistling, picked up the oxyacetylene blowpipe, regarding it somewhat as a dog fancier might gaze at an exceptionally fine pup. "Hold up your finger," said he to the astronomer. "That's right--like that!"

Thrusting the blowpipe forward, he allowed the hissing blue-white flame to wrap itself round the outer wall of the tube--a flame which Thornton knew could melt its way through a block of steel--but the astronomer felt no sensation of heat, although he not unnaturally expected the member to be incinerated.

"Queer, eh?" said Bennie. "Absolute insulation! Beats the thermos bottle, and requires no vacuum. It isn't quite what I want though, because the disintegrating rays which the ring discharge gives out break down the zirconium, which isn't an end-product of radioactivity. The pressure in the capsule rises, due to the liberation of helium, and it blows up, and the landlady or the police come up and bother me."

Thornton was scrutinizing Bennie's rough diagram. "This ring discharge," he meditated; "I wonder if it isn't something like a sunspot. You know the spots are electron vortices with strong magnetic fields. I'll bet you the Savaroff disintegrating rays come from the spots and not from the whole surface of the sun!"

"My word," said Bennie, with a grin of delight, "you occasionally have an illuminating idea, even if you are a musty astronomer. I always thought you were a sort of calculating machine, who slept on a logarithm table. I owe you two drinks for that suggestion, and to scare a thirst into you I'll show you an experiment that no living human being has ever seen before. I can't make very powerful disintegrating rays yet, but I can break down uranium, which is the easiest of all. Later on I'll be able to disintegrate anything, if I have luck--that is, anything except end-products. Then you'll see things fly. But, for the present, just this." He picked up a thin plate of white metal. "This is the metal we're going to attack, uranium--the parent of radium--and the whole radioactive series, ending with the end-product lead."

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 phosphorescence of the air through which they pass."

He arranged a thick slab of plate glass 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 mass, but enormous velocity. See?"

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

"Of course this is only a toy experiment," Bennie continued. "It is what the dancing pithballs 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 space, 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 quantities of matter that the mass 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 retard 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 Jap maybe, but never Hiroshito! 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." _
