At ten o'clock one evening, shortly after the occurrences heretofore described, an extraordinary conference occurred at the White House, probably the most remarkable ever held there or elsewhere. At the long table at which the cabinet meetings took place sat six gentlemen in evening dress, each trying to appear unconcerned, if not amused. At the head of the table was the President of the United States; next to him Count von Koenitz, the German Ambassador, representing the Imperial[1] German Commissioners, who had taken over the reins of the German Government after the abdication of the Kaiser; and, on the opposite side, Monsieur Emil Liban, Prince Rostoloff, and Sir John Smith, the respective ambassadors of France, Russia, and Great Britain. The sixth person was Thornton, the astronomer.

The President had only succeeded in bringing this conference about after the greatest effort and the most skilful diplomacy—in view of the extreme importance which, he assured them all, he attached to the matters which he desired to lay before them. Only for this reason had the ambassadors of warring nations consented to meet—unofficially as it were.

"With great respect, your Excellency," said Count von Koenitz, "the matter is preposterous—as much so as a fairy tale by Grimm! This wireless operator of whom you speak is lying about these messages. If he received them at all—a fact which hangs solely upon his word—he received them after and not before the phenomena recorded."

The President shook his head. "That might hold true of the first message—the one received July 19th," said he, "but the second message, foretelling the lengthening of July 27th, was delivered on that day, and was in my hands before the disturbances occurred."

Von Koenitz fingered his moustache and shrugged his shoulders. It was clear that he regarded the whole affair as absurd, undignified.

Monsieur Liban turned impatiently from him.

"Your Excellency," he said, addressing the President, "I cannot share the views of Count von Koenitz. I regard this affair as of the most stupendous importance. Messages or no messages, extraordinary natural phenomena are occurring which may shortly end in the extinction of human life upon the planet. A power which can control the length of the day can annihilate the globe."

"You cannot change the facts," remarked Prince Rostoloff sternly to the German Ambassador. "The earth has changed its orbit. Professor Vaskofsky, of the Imperial College, has so declared. There is some cause. Be it God or devil, there is a cause. Are we to sit still and do nothing while the globe's crust freezes and our armies congeal into corpses?" He trembled with agitation.

"Calm yourself, mon cher Prince!" said Monsieur Liban. "So far we have gained fifteen minutes and have lost nothing! But, as you say, whether or not the sender of these messages is responsible, there is a cause, and we must find it."

"But how? That is the question," exclaimed the President almost apologetically, for he felt, as did Count von Koenitz, that somehow an explanation would shortly be forthcoming that would make this conference seem the height of the ridiculous. "I have already," he added hastily, "instructed the entire force of the National Academy of Sciences to direct its energies toward the solution of these phenomena. Undoubtedly Great Britain, Russia, Germany, and France are doing the same. The scientists report that the yellow aurora seen in the north, the earthquakes, the variation of the compass, and the eccentricities of the barometer are probably all connected more or less directly with the change in the earth's orbit. But they offer no explanation. They do not suggest what the aurora is nor why its appearance should have this effect. It, therefore, seems to me clearly my duty to lay before you all the facts as far as they are known to me. Among these facts are the mysterious messages received by wireless at the Naval Observatory immediately preceding these events."

"Post hoc, ergo propter hoc!" half sneered Von Koenitz.

The President smiled wearily.

"What do you wish me to do?" he asked, glancing round the table. "Shall we remain inactive? Shall we wait and see what may happen?"

"No! No!" shouted Rostoloff, jumping to his feet. "Another week and we may all be plunged into eternity. It is suicidal not to regard this matter seriously. We are sick from war. And perhaps Count von Koenitz, in view of the fall of Berlin, would welcome something of the sort as an honourable way out of his country's difficulties."

"Sir!" cried the count, leaping to his feet. "Have a care! It has cost Russia four million men to reach Berlin. When we have taken Paris we shall recapture Berlin and commence the march of our victorious eagles toward Moscow and the Winter Palace."

"Gentlemen! Gentlemen! Be seated, I implore you!" exclaimed the President.

The Russian and German ambassadors somewhat ungraciously resumed their former places, casting at each other glances of undisguised contempt.

"As I see the matter," continued the President, "there are two distinct propositions before you: The first relates to how far the extraordinary events of the past week are of such a character as to demand joint investigation and action by the Powers. The second involves the cause of these events and their connection with and relation to the sender of the messages signed Pax. I shall ask you to signify your opinion as to each of these questions."

"I believe that some action should be taken, based on the assumption that they are manifestations of one and the same power or cause," said Monsieur Liban emphatically.

"I agree with the French Ambassador," growled Rostoloff.

"I am of opinion that the phenomena should be the subject of proper scientific investigation," remarked Count von Koenitz more calmly. "But as far as these messages are concerned they are, if I may be pardoned for saying so, a foolish joke. It is undignified to take any cognizance of them."

"What do you think, Sir John?" asked the President, turning to the English Ambassador.

"Before making up my mind," returned the latter quietly, "I should like to see the operator who received them."

"By all means!" exclaimed Von Koenitz.

The President pressed a button and his secretary entered.

"I had anticipated such a desire on the part of all of you," he announced, "and arranged to have him here. He is waiting outside. Shall I have him brought in?"

"Yes! Yes!" answered Rostoloff. And the others nodded.

The door opened, and Bill Hood, wearing his best new blue suit and nervously twisting a faded bicycle cap between his fingers, stumbled awkwardly into the room. His face was bright red with embarrassment and one of his cheeks exhibited a marked protuberance. He blinked in the glare of the electric light.

"Mr. Hood," the President addressed him courteously, "I have sent for you to explain to these gentlemen, who are the ambassadors of the great European Powers, the circumstances under which you received the wireless messages from the unknown person describing himself as 'Pax.'"

Hood shifted from his right to his left foot and pressed his lips together. Von Koenitz fingered the waxed ends of his moustache and regarded the operator whimsically.

"In the first place," went on the President, "we desire to know whether the messages which you have reported were received under ordinary or under unusual conditions. In a word, could you form any opinion as to the whereabouts of the sender?"

Hood scratched the side of his nose in a manner politely doubtful.

"Sure thing, your Honour," he answered at last. "Sure the conditions was unusual. That feller has some juice and no mistake."

"Juice?" inquired Von Koenitz.

"Yare—current. Whines like a steel top. Fifty kilowatts sure, and maybe more! And a twelve-thousand-metre wave."

"I do not fully understand," interjected Rostoloff. "Please explain, sir."

"Ain't nothin' to explain," returned Hood. "He's just got a hell of a wave length, that's all. Biggest on earth. We're only tuned for a three-thousand-metre wave. At first I could hardly take him at all. I had to throw in our new Henderson ballast coils before I could hear properly. I reckon there ain't another station in Christendom can get him."

"Ah," remarked Von Koenitz. "One of your millionaire amateurs, I suppose."

"Yare," agreed Hood. "I thought sure he was a nut."

"A what?" interrupted Sir John Smith.

"A nut," answered Hood. "A crank, so to speak."

"Ah, 'krank'!" nodded the German. "Exactly—a lunatic! That is precisely what I say!"

"But I don't think it's no nut now," countered Hood valiantly. "If he is a bug he's the biggest bug in all creation, that's all I can say. He's got the goods, that's what he's got. He'll do some damage before he gets through."

"Are these messages addressed to anybody in particular?" inquired Sir John, who was studying Hood intently.

"Well, they are and they ain't. Pax—that's what he calls himself—signals NAA, our number, you understand, and then says what he has to say to the whole world, care of the United States. The first message I thought was a joke and stuck it in a book I was reading, 'Silas Snooks'——"

"What?" ejaculated Von Koenitz impatiently.

"Snooks—man's name—feller in the book—nothing to do with this business," explained the operator. "I forgot all about it. But after the earthquake and all the rest of the fuss I dug it out and gave it to Mr. Thornton. Then on the 27th came the next one, saying that Pax was getting tired of waiting for us and was going to start something. That came at one o'clock in the afternoon, and the fun began at three sharp. The whole observatory went on the blink. Say, there ain't any doubt in your minds that it's him, is there?"

Von Koenitz looked cynically round the room.

"There is not!" exclaimed Rostoloff and Liban in the same breath.

The German laughed.

"Speak for yourselves, Excellencies," he sneered. His tone nettled the wireless representative of the sovereign American people.

"Do you think I'm a liar?" he demanded, clenching his jaw and glaring at Von Koenitz.

The German Ambassador shrugged his shoulders again. Such things were impossible in a civilized country—at Potsdam—but what could you expect——

"Steady, Hood!" whispered Thornton.

"Remember, Mr. Hood, that you are here to answer our questions," said the President sternly. "You must not address his Excellency, Baron von Koenitz, in this fashion."

"But the man was making a monkey of me!" muttered Hood. "All I say is, look out. This Pax is on his job and means business. I just got another call before I came over here—at nine o'clock."

"What was its purport?" inquired the President.

"Why, it said Pax was getting tired of nothing being done and wanted action of some sort. Said that men were dying like flies, and he proposed to put an end to it at any cost. And—and——"

"Yes! Yes!" ejaculated Liban breathlessly.

"And he would give further evidence of his control over the forces of nature to-night."

"Ha! Ha!" Von Koenitz leaned back in amusement. "My friend," he chuckled, "you—are—the 'nut'!"

What form Hood's resentment might have taken is problematical; but as the German's words left his mouth the electric lights suddenly went out and the windows rattled ominously. At the same moment each occupant of the room felt himself sway slightly toward the east wall, on which appeared a bright yellow glow. Instinctively they all turned to the window which faced the north. The whole sky was flooded with an orange-yellow aurora that rivalled the sunlight in intensity.

"What'd I tell you?" mumbled Hood.

The Executive Mansion quivered, and even in that yellow light the faces of the ambassadors seemed pale with fear. And then as the glow slowly faded in the north there floated down across the aperture of the window something soft and fluffy like feathers. Thicker and faster it came until the lawn of the White House was covered with it. The air in the room turned cold. Through the window a large flake circled and lit on the back of Rostoloff's head.

"Snow!" he cried. "A snowstorm—in August!"

The President arose and closed the window. Almost immediately the electric lights burned up again.

"Now are you satisfied?" cried Liban to the German.

"Satisfied?" growled Von Koenitz. "I have seen plenty of snowstorms in August. They have them daily in the Alps. You ask me if I am satisfied. Of what? That earthquakes, the aurora borealis, electrical disturbances, snowstorms exist—yes. That a mysterious bugaboo is responsible for these things—no!"

"What, then, do you require?" gasped Liban.

"More than a snowstorm!" retorted the German. "When I was a boy at the gymnasium we had a thunderstorm with fishes in it. They were everywhere one stepped, all over the ground. But we did not conclude that Jonah was giving us a demonstration of his power over the whale."

He faced the others defiantly; in his voice was mockery.

"You may retire, Mr. Hood," said the President. "But you will kindly wait outside."

"That is an honest man if ever I saw one, Mr. President," announced Sir John, after the operator had gone out. "I am satisfied that we are in communication with a human being of practically supernatural powers."

"What, then, shall be done?" inquired Rostoloff anxiously. "The world will be annihilated!"

"Your Excellencies"—Von Koenitz arose and took up a graceful position at the end of the table—"I must protest against what seems to me to be an extraordinary credulity upon the part of all of you. I speak to you as a rational human being, not as an ambassador. Something has occurred to affect the earth's orbit. It may result in a calamity. None can foretell. This planet may be drawn off into space by the attraction of some wandering world that has not yet come within observation. But one thing we know: No power on or of the earth can possibly derange its relation to the other celestial bodies. That would be, as you say here, 'lifting one's self by one's own boot-straps.' I do not doubt the accuracy of your clocks and scientific instruments. Those of my own country are in harmony with yours. But to say that the cause of all this is a man is preposterous. If the mysterious Pax makes the heavens fall, they will tumble on his own head. Is he going to send himself to eternity along with the rest of us? Hardly! This Hood is a monstrous liar or a dangerous lunatic. Even if he has received these messages, they are the emanations of a crank, as, he says, he himself first suspected. Let us master this hysteria born of the strain of constant war. In a word, let us go to bed."

"Count von Koenitz," replied Sir John after a pause, "you speak forcefully, even persuasively. But your argument is based upon a proposition that is scientifically fallacious. An atom of gunpowder can disintegrate itself, 'lift itself by its own boot-straps!' Why not the earth? Have we as yet begun to solve all the mysteries of nature? Is it inconceivable that there should be an undiscovered explosive capable of disrupting the globe? We have earthquakes. Is it beyond imagination that the forces which produce them can be controlled?"

"My dear Sir John," returned Von Koenitz courteously, "my ultimate answer is that we have no adequate reason to connect the phenomena which have disturbed the earth's rotation with any human agency."

"That," interposed the President, "is something upon which individuals may well differ. I suppose that under other conditions you would be open to conviction?"

"Assuredly," answered Von Koenitz. "Should the sender of these messages prophesy the performance of some miracle that could not be explained by natural causes, I would be forced to admit my error."

Monsieur Liban had also arisen and was walking nervously up and down the room. Suddenly he turned to Von Koenitz and in a voice shaking with emotion cried: "Let us then invite Pax to give us a sign that will satisfy you."

"Monsieur Liban," replied Von Koenitz stiffly, "I refuse to place myself in the position of communicating with a lunatic."

"Very well," shouted the Frenchman, "I will take the responsibility of making myself ridiculous. I will request the President of the United States to act as the agent of France for this purpose."

He drew a notebook and a fountain pen from his pocket and carefully wrote out a message which he handed to the President. The latter read it aloud:

"Pax: The Ambassador of the French Republic requests me to communicate to you the fact that he desires some further evidence of your power to control the movements of the earth and the destinies of mankind, such phenomena to be preferably of a harmless character, but inexplicable by any theory of natural causation. I await your reply.

"The President of the United States.
