predecessors, heightened the tension like the crack of a whip.
All eyes flew to the timepiece. It registered thirty-four seconds past 11:49 o'clock.
Therefore, the next tremor would occur at precisely forty seconds after midnight.
If the unknown "KWO" were an actual being, and kept his word—at that time the shocks would begin to subside!
The suspense became terrible. The faces of the scientists were drawn and pale. Beads of perspiration stood out on every brow. The minutes passed.
The electric correcting-device on the clock gave a sharp click, denoting midnight. Forty seconds more! The suffocating atmosphere seemed almost to turn cold under the pressure of anxiety.
Then, almost before any one could realize it, the earthquake had come and gone! And not one particle of diminution in its violence had been felt!
A sigh of relief involuntarily passed around the room. Few moved or spoke, but there was a lessening of the strain on many faces. It was too soon yet, of course, to be sure, but—in most hearts there began to dawn a faint ray of hope that, after all, this "dictator of human destiny" might be a myth.
But suddenly Professor Frisby raised his hand to command quiet, and bent more intently over his telephone.
A short silence followed. Then he turned to the gentlemen and announced in a voice that seemed curiously dry:
"The operator reports that no wireless signal accompanied this last earthquake."
Again the nerve tension in the assembly leaped like an electric spark. Several more minutes passed in silence.
Then came another quake.
Had there been a decrease in its force? Opinion was divided.
All eyes sped to Professor Whiteman, but he remained absorbed at his seismographs.
In this silence and keen suspense eleven minutes and six seconds again dragged by. Another earthquake came and went. Once more Professor Frisby announced that there had been no wireless signal attending the tremor. The savants began to settle themselves for a further wait, when—
Professor Whiteman left his instrument and came slowly forward. In the dim light his face looked lined and gray. Before the rows of seats he stopped and faltered a moment. Then he said:
"Gentlemen, the earthquakes are beginning to subside!"
For a moment the scientists sat as if stunned. Everyone was too appalled to speak or move. Then the tension was broken by the rush of the Consolidated News men from the room to get their momentous tidings out to the world.
After that the ground shocks died out with increasing rapidity. In an hour they had ceased entirely, and the tortured planet once more was still.
But the tumult among the people had only started!
With a sudden shock the globe's inhabitants realized, that they were in the grip of an unknown being endowed with supernatural power. Whether he were man or demigod, sane or mad, well-disposed or malignant—no one could guess. Where was his dwelling-place, whence the source of his power, what would be the first manifestation of his authority, or how far would he seek to enforce his control? Only time could answer.
As this situation dawned upon men, their fears burst all bounds. Frantic excitement took possession of the throngs.
Only at the naval observatory in Washington was there calmness and restraint. The gathering of scientists spent the night in earnest deliberation of the course to be followed.
Finally it was decided that nothing should be done for the present; they would merely await events. When it had suited the mysterious "KWO" to announce himself to the world he had done so. Thereafter, communication with him had been impossible. Doubtless when he was ready to speak again he would break his silence—not before. It was reasonable to suppose that, now be had proved his power, he would not be long in stating his wishes or commands.
Events soon showed this surmise was correct.
Promptly at noon the next day—there having in the meantime been no recurrence of the earthquakes or electrical disturbances of the ether—the wireless at the naval observatory again received the mysterious call for the presiding officer of the scientific congress.
Professor Whiteman had remained at the observatory, in anticipation of such a summons, and soon he, with other leading members of the scientific assembly, was at the side of the operator in the wireless room.
Almost immediately after the call:
"KWO— KWO—KWO"
went forth into the ether, there came a response and the operator started writing:
"To the Presiding Officer of the International Scientific Congress:
"Communicate this to the various governments of the earth:
"As a preliminary to the establishment of my sole rule throughout the world, the following demands must be complied with:
"First: All standing armies shall be disbanded, and every implement of warfare, of whatsoever nature, destroyed.
"Second: All war vessels shall be assembled—those of the Atlantic fleets midway between New York and Gibraltar, those of the Pacific fleets midway between San Francisco and Honolulu—and sunk.
"Third: One-half of all the monetary gold supply of the world shall be collected and turned over to my agents at places to be announced later.
"Fourth: At noon on the third day after the foregoing demands have been complied with, all the existing governments shall resign and surrender their powers to my agents, who will be on hand to receive them.
"In my next communication I will fix the date for the fulfillment of these demands.
"The alternative is the destruction of the globe. "KWO."
It was on the evening of this eventful day that Dr. Gresham and I returned from Labrador. A little after 10 o'clock we landed in New York and, taking a taxicab at the pier, started for our bachelor quarters in apartments near each other west of Central Park.
As we reached the center of town we were amazed at the excited crowds that filled the streets and at the prodigious din raised by newsboys selling extras.
We stopped the car and bought papers. Huge black headings told the story at a glance. Also, at the bottom of the first page, we found a brief chronological summary of all that had happened, from the very beginning of the mysterious wireless signals three months before. We scanned it eagerly.
When I finished the newspaper article I turned to my companion—and was struck with horror at the change in his appearance!
He was crumpled down upon the seat of the taxi, and his face had taken on a ghastly hue. At first I though he had suffered a stroke. Only his eyes held a sign of life, and they seemed fixed on something far away—something too terrifying to be a part of the world around us.
