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
