they evolved. But they did it, they did it!"

Close to the coils a dim light was glowing. It was a pin-point of radiance in the half-darkness about them. The two men bent closer.

"See," directed MacGregor, "it strikes on this mirror—bright metal and parabolic. It disperses the light, doesn't concentrate it! Ah! Here is another, and another. This one is bent—broken. They are adjustable. Hm! Micrometer accuracy for reducing the light. The last one could reflect through this slot. It's light that does it, Thurston, it's light that does it!"

"Does what?" Thurston had followed the other's analysis of the diffusion process. "The light that would finally reach that slot would be hardly perceptible."

"It's the agent," said MacGregor, "the activator—the catalyst! What does it strike upon? I must know—I must!"

The waves were splashing outside the shell. Thurston turned in a feverish search of the unexplored depths. There was a surprising simplicity, an absence of complicated mechanism. The generator, with its tremendous braces to carry its thrust to the framework itself, filled most of the space. Some of the ribs were thicker, he noticed. Solid metal, as if they might carry great weights. Resting upon them were ranged numbers of objects. They were like eggs, slender, and inches in length. On some were propellers. They worked through the shells on long slender rods. Each was threaded finely—an adjustable arm engaged the thread. Thurston called excitedly to the other.

"Here they are," he said. "Look! Here are the shells. Here's what blew us up!"

He pointed to the slim shafts with their little propellerlike fans. "Adjustable, see? Unwind in their fall ... set 'em for any length of travel ... fires the charge in the air. That's how they wiped out our air fleet."

There were others without the propellers; they had fins to hold them nose downward. On each nose was a small rounded cap.

"Detonators of some sort," said MacGregor. "We've got to have one. We must get it out quick; the tide's coming in." He laid his hands upon one of the slim, egg-shaped things. He lifted, then strained mightily. But the object did not rise; it only rolled sluggishly.

The scientist stared at it amazed. "Specific gravity," he exclaimed, "beyond anything known! There's nothing on earth ... there is no such substance ... no form of matter...." His eyes were incredulous.

"Lots to learn," Thurston answered grimly. "We've yet to learn how to fight off the other four."

The other nodded. "Here's the secret," he said. "These shells liberate the same gas that drives the machine. Solve one and we solve both—then we learn how to combat it. But how to remove it—that is the problem. You and I can never lift this out of here."

His glance darted about. There was a small door in the metal beam. The groove in which the shells were placed led to it; it was a port for launching the projectiles. He moved it, opened it. A dash of spray struck him in the face. He glanced inquiringly at his companion.

"Dare we do it?" he asked. "Slide one of them out?"

Each man looked long into the eyes of the other. Was this, then, the end of their terrible night? One shell to be dropped—then a bursting volcano to blast them to eternity....

"The boys in the planes risked it,"[181] said Thurston quietly. "They got theirs." He stopped for a broken fragment of steel. "Try one with a fan on; it hasn't a detonator."

The men pried at the slim thing. It slid slowly toward the open port. One heave and it balanced on the edge, then vanished abruptly. The spray was cold on their faces. They breathed heavily with the realization that they still lived.

There were days of horror that followed, horror tempered by a numbing paralysis of all emotions. There were bodies by thousands to be heaped in the pit where San Diego had stood, to be buried beneath countless tons of debris and dirt. Trains brought an army of helpers; airplanes came with doctors and nurses and the beginning of a mountain of supplies. The need was there; it must be met. Yet the whole world was waiting while it helped, waiting for the next blow to fall.

Telegraph service was improvised, and radio receivers rushed in. The news of the world was theirs once more. And it told of a terrified, waiting world. There would be no temporizing now on the part of the invaders. They had seen the airplanes swarming from the ground—they would know an airdrome next time from the air. Thurston had noted the windows in the great shell, windows of dull-colored glass which would protect the darkness of the interior, essential to life for the horrible occupant, but through which it could see. It could watch all directions at once.

The great shell had vanished from the shore. Pounding waves and the shifting sands of high tide had obliterated all trace. More than once had Thurston uttered devout thanks for the chance shell from an anti-aircraft gun that had entered the funnel beneath the machine, had bent and twisted the arrangement of mirrors that he and MacGregor had seen, and, exploding, had cracked and broken the domed roof of the bulb. They had learned little, but MacGregor was up north within reach of Los Angeles laboratories. And he had with him the slim cylinder of death. He was studying, thinking.

Telephone service had been established for official business. The whole nation-wide system, for that matter, was under military control. The Secretary of War had flown back to Washington. The whole world was on a war basis. War! And none knew where they should defend themselves, nor how.

An orderly rushed Thurston to the telephone. "You are wanted at once; Los Angeles calling."

The voice of MacGregor was cool and unhurried as Thurston listened. "Grab a plane, old man," he was saying, "and come up here on the jump."

The phrase brought a grim smile to Thurston's tired lips. "Hell's popping!" the Secretary of War had added on that evening those long ages before. Did MacGregor have something? Was a different kind of hell preparing to pop? The thoughts flashed through the listener's mind.

"I need a good deputy," MacGregor said. "You may be the whole works—may have to carry on—but I'll tell you it all later. Meet me at the Biltmore."

"In less than two hours," Thurston assured him.

A plane was at his disposal. Riley's legs were functioning again, after a fashion. They kept the appointment with minutes to spare.

"Come on," said MacGregor, "I'll talk to you in the car." The automobile whirled them out of the city to race off upon a winding highway that climbed into far hills. There was twenty miles of this; MacGregor had time for his talk.

"They've struck," he told the two men. "They were over Germany yesterday. The news was kept quiet: I got the last report a half-hour ago. They pretty well wiped out Berlin. No[182] air-force there. France and England sent a swarm of planes, from the reports. Poor devils! No need to tell you what they got. We've seen it first hand. They headed west over the Atlantic, the four machines. Gave England a burst or two from high up, paused over New York, then went on. But they're here somewhere, we think. Now listen:

"How long was it from the time when you saw the first monster until we heard from them again?"

Thurston forced his mind back to those days that seemed so far in the past. He tried to remember.

"Four days," broke in Riley. "It was the fourth day after we found the devil feeding."

"Feeding!" interrupted the scientist. "That's the point I am making. Four days. Remember that!

"And we knew they were down in the Argentine five days ago—that's another item kept from an hysterical public. They slaughtered some thousands of cattle; there were scores of them found where the devils—I'll borrow Riley's word—where the devils had fed. Nothing left but hide and bones.

"And—mark this—that was four days before they appeared over Berlin.

"Why? Don't ask me. Do they have to lie quiet for that period miles up there in space? God knows. Perhaps! These things seem outside the knowledge of a deity. But enough of that! Remember: four days! Let us assume that there is this four days waiting period. It will help us to time them. I'll come back to that later.

"Here is what I have been doing. We know that light is a means of attack. I believe that the detonators we saw on those bombs merely opened a seal in the shell and forced in a flash of some sort. I believe that radiant energy is what fires the blast.

"What is it that explodes? Nobody knows. We have opened the shell, working in the absolute blackness of a room a hundred feet underground. We found in it a powder—two powders, to be exact.

"They are mixed. One is finely divided, the other rather granular. Their specific gravity is enormous, beyond anything known to physical science unless it would be the hypothetical neutron masses we think are in certain stars. But this is not matter as we know matter; it is something new.

"Our theory is this: the hydrogen atom has been split, resolved into components, not of electrons and the proton centers, but held at some halfway point of decomposition. Matter composed only of neutrons would be heavy beyond belief. This fits the theory in that respect. But the point is this: When these solids are formed—they are dense—they represent in a cubic centimeter possibly a cubic mile of hydrogen gas under normal pressure. That's a guess, but it will give you the idea.

"Not compressed, you understand, but all the elements present in other than elemental form for the reconstruction of the atom ... for a million billions of atoms.

"Then the light strikes it. These dense solids become instantly a gas—miles of it held in that small space.

"There you have it: the gas, the explosion, the entire absence of heat—which is to say, its terrific cold—when it expands."

Slim Riley was looking bewildered but game. "Sure, I saw it snow," he affirmed, "so I guess the rest must be O.K. But what are we going to do about it? You say light kills 'em, and fires their bombs. But how can we let light into those big steel shells, or the little ones either?"

"Not through those thick walls," said MacGregor. "Not light. One of our anti-aircraft shells made a direct hit. That might not happen again in a million shots. But there are other forms of radiant energy that do penetrate steel...."

[183]

The car had stopped beside a grove of eucalyptus. A barren, sun-baked hillside stretched beyond. MacGregor motioned them to alight.

Riley was afire with optimism. "And do you believe it?" he asked eagerly. "Do you believe that we've got 'em licked?"

Thurston, too, looked into MacGregor's face: Riley was not the only one who needed encouragement. But the gray eyes were suddenly tired and hopeless.

"You ask what I believe," said the scientist slowly. "I believe we are witnessing the end of the world, our world of humans, their struggles, their grave hopes and happiness and aspirations...."

He was not looking at them. His gaze was far off in space.

"Men will struggle and fight with their puny weapons, but these monsters will win, and they will have their way with us. Then more of them will come. The world, I believe, is doomed...."

He straightened his shoulders. "But we can die fighting," he added, and pointed over the hill.

"Over there," he said, "in the valley beyond, is a charge of their explosive and a little apparatus of mine. I intend to fire the charge from a distance of three hundred yards. I expect to be safe, perfectly safe. But accidents happen.

"In Washington a plane is being prepared. I have given instructions through hours of phoning. They are working night and day. It will contain a huge generator for producing my ray. Nothing new! Just the product of our knowledge of radiant energy up to date. But the man who flies that plane will die—horribly. No time to experiment with protection. The rays will destroy him, though he may live a month.

"I am asking you," he told Cyrus Thurston, "to handle that plane. You may be of service to the world—you may find you are utterly powerless. You surely will die. But you know the machines and the monsters; your knowledge may be of value in an attack." He waited. The silence lasted for only a moment.

"Why, sure," said Cyrus Thurston.

He looked at the eucalyptus grove with earnest appraisal. The sun made lovely shadows among their stripped trunks: the world was a beautiful place. A lingering death, MacGregor had intimated—and horrible.... "Why, sure," he repeated steadily.

Slim Riley shoved him firmly aside to stand facing MacGregor.

"Sure, hell!" he said. "I'm your man, Mr. MacGregor.

"What do you know about flying?" he asked Cyrus Thurston. "You're good—for a beginner. But men like you two have got brains, and I'm thinkin' the world will be needin' them. Now me, all I'm good for is holdin' a shtick"—his brogue had returned to his speech, and was evidence of his earnestness.

"And, besides"—the smile faded from his lips, and his voice was suddenly soft—"them boys we saw take their last flip was just pilots to you, just a bunch of good fighters. Well, they're buddies of mine. I fought beside some of them in France.... I belong!"

He grinned happily at Thurston. "Besides," he said, "what do you know about dog-fights?"

MacGregor gripped him by the hand. "You win," he said. "Report to Washington. The Secretary of War has all the dope."

He turned to Thurston. "Now for you!
