"No, and hundreds and thousands of lives are being lost every moment now. Frantic thousands are swamping boats of all sizes in their craze to get away. Dozens of overloaded vessels have capsized and the surface of the river is alive with doomed people, fighting the water and one another...."

Jeter clicked up the receiver on the horror, knowing there was nothing he could do. There would be no end to the loss of life until some measure of sanity had been argued into crazed humanity.

All the time he kept wondering.

What was doing all this awful business? He surmised that some anti-gravitational agency was responsible for the levitation of the Vandercook building, but what sort of intelligence was directing it? Was the intelligence human? b.e.s.t.i.a.l? Maniacal? Or was it something from Outside? Jeter did not think the latter could be considered. He didn't believe that any planet, possibly inhabited, was close enough to make a visit possible. At any rate, he felt that there should be some sort of warning. He held to the belief that the whole thing was caused by human, and earthly, intelligence.

But why? The world was at peace. And yet....

Thousands of lives had been snuffed out, a twelve-story building had leaped five thousand feet into the air, and the world's biggest bridge had turned upstream as though turning its back against the mad traffic it had at last been called upon to bear.

Eyer was going over their plane with the visitors, men of intellect who were taking notes at top speed, men who knew planes and were quick to grasp new appliances.

"Have any of you got the whole story now?" Eyer asked.

A half dozen men nodded.

"Then pa.s.s your knowledge on to the others. Jeter and I must get ready to be off. Every minute we delay costs untold numbers of lives."

Willing hands rolled their ship out to their own private runway, while Jeter and Eyer made last minute preparations. There was the matter of food, of oxygen necessary so far above the Earth, of clothing. All had been provided for and their last duties were largely those of checking and rechecking, to make sure no fatal errors in judgment had been made.

Eyer was to fly the ship in the beginning.

A small crowd watched as the partners, white of face now in the last minutes of their stay on Earth--which they might never touch again in life--climbed into their cabin, which was capable of being sealed against the cold of the heights and the lack of breathable oxygen.

n.o.body smiled at them, for the world had stopped smiling.

n.o.body waved at them, for a wave would have been frivolous.

n.o.body cheered or even shouted--but the two knew that the best wishes, the very hopes for life, of all the land, went with them into the ghastly unknown.

CHAPTER V

_Into the Void_

Their watches and the clock in the plane were synchronized with Hadley's time, which was Eastern Standard, and as soon as the plane had reached eight thousand feet alt.i.tude, Jeter spoke into the radiophone and arranged for a connection with the office of Hadley.

Hadley himself soon spoke into Jeter's ear.

"Yes, Jeter?"

"See that someone is always at your radiophone to listen to us. I'll keep you informed of developments as long as possible. Everything is running like clockwork so far. How is it with you?"

"Two additional buildings, older buildings of the city, have been lifted some hundreds of feet above ground level, then dropped back upon their own foundations, to be broken apart. Many lives lost despite the fact that the city will be deserted within a matter of hours. It seems that the--shall we say enemy?--is concentrating only on old buildings."

"Perhaps they wish to preserve the new ones," said Jeter quietly.

"What? Why?"

"For their own use, perhaps; who knows? Keep me informed of every eventuality. If the center of force which seems to be causing all this havoc shifts in any direction, advise us at once."

"All right, Jeter."

Jeter broke the connection temporarily. Hadley could get him at any moment. A buzzer would sound inside the almost noiseless cabin when anyone wished to contact him over the radiophone.

Eyer was concentrating on the controls. The plane was climbing in great sweeping spirals. Its speed was a hundred and fifty miles an hour. Their air speed indicator was capable of registering eight hundred miles an hour. They hoped to attain that speed and more, flying on an even keel above ninety thousand feet.

Both Eyer and Jeter were perfect navigators. If, as they hoped, they could reach ninety thousand or more, they could cross the whole United States in four hours or less. They could quarter the country, winged bloodhounds of s.p.a.ce, seeking their quarry.

Jeter studied the sky above them through their special telescopes, seeking some hint of the location of the point of departure of that devastating column of light. He could think of no ray that would nullify gravitation--yet that column of light had been the visual manifestation that the thing had somehow been brought about.

If this were true, was the enemy vulnerable? Was his base of attack capable of being destroyed or crippled if anything happened to the column of light? There was no way of knowing--yet. A search of the sky above Manhattan failed to disclose any visible substance from which the light beam might emanate. That seemed to indicate some unbelievable height. Yet, Kress must have reached that base. Else why had he been destroyed and sent back to Jeter and Eyer as a challenge?

Jeter's mind went back to Kress. Frozen solid ... but that could have been caused by his downward plunge through s.p.a.ce. And what had happened to Kress' plane? No word had been received concerning it up to the time of the Jeter-Eyer departure. Had the "enemy" taken possession of it?

The whole thing seemed absurd. n.o.body knew better than Jeter that he was working literally and figuratively in the dark. He was doing little better than guessing. He felt sure of but one thing, that the agency which was wreaking the havoc was a human one, and he was perfectly willing to match his wits and Eyer's against any human intelligence.

Jeter slipped into the cushioned seat beside Eyer.

The altimeter registered fifteen thousand feet. New York was just a blur against the abysmal darkness under their careening wings.

"You've never ventured an opinion, Tema," said Jeter softly, "even to me."

Eyer grinned.

"Who knows?" he said. "It may all be just the very latest thing in aerial attack. If so, what country or coalition of countries harbor designs against our good Uncle Sam? j.a.pan? China?"

"How do you explain the Vandercook incident? The bridge thing? The rise and fall of the other skysc.r.a.pers?"

"Some substance or ray capable of being controlled and directed. It creates a field, of any size desired, in which gravitation is--well, shall we say erased? Then any solid which is thus made weightless could be lifted by the two good hands of a strong man, or even of a weak one.

How does that check with your guessing?"

Jeter shook his head ruefully.

"I've arrived at the same conclusions as yourself, Tema," he said. "I know we're all guessing. I know we're probably climbing off the Earth on a wild-goose chase from which we haven't a chance of returning alive. I know we're a pair of fools to think of matching a few drums of gas and a bunch of popguns against the equipment of an enemy capable of moving mountains--but what else is there to do?"

"Nothing," said Eyer cheerfully, "and I've got a feeling that you and I will manage to acquit ourselves with credit."

The radiophone buzzer sounded.
