attacked.

"I think, Earthman, that you are tired, and should rest, lest you make a tired thought and do great harm," suggested Zezdon Afthen.

"I want to finish it!" replied Arcot, sharply. He was tired.

In seconds the Thought was once more over that fortified station in the mountains—and the triple-ray reached out—and suddenly, about the ship, was a wall of absolute, utter blackness. The triple-ray touched it, and exploded into coruscating, blinding energy. It could not penetrate it. More energy lashed at the wall of blackness as the operators within the sphere-fort turned in the energy of all the generators under their control. The ground about the fort was a great lake of dazzling lava as far as the eye could see, for the triple-ray was releasing its energy, and the wall of black was releasing an equal, and opposing energy!

"Stopped!" cried Arcot happily. "Now here is where we give them something to think about. The magnet and the heat!"

He turned the two enormous forces simultaneously on the point where he knew the fort was, though it was invisible behind the wall of black that protected him. From his side, the energy of the spot where all the system of Thett was throwing its forces, was invisible.

Then he released them. Instantly there was a terrific gout of light on that wall of blackness. The ship trembled, and space turned gray about them. The black wall dissolved into grayness in one spot, as a flood of energy beyond comprehension exploded from it. The enormously strong cosmium wall dented as the pressure of the escaping radiation struck it, and turned X-ray hot under the minute percentage it absorbed. The triple-ray bent away, and faded to black as the cosmic force playing about it, actually twisted space beyond all power of its mechanism to overcome. Then, in the tiniest fraction of a second it was over, and again there was blackness and only the brilliant, blinding blue of the cosmium wall testified to its enormous temperature, cooling now far more slowly through green to red.

"Lord—you're right, Zezdon Afthen. I'm going to sleep," called Arcot. And the ship was suddenly far, far away from Thett. Morey took over, and Arcot slept. First Morey straightened the uninjured wall and ironed out the dents.

"What, Morey, is the wall of Blackness?" asked Stel Felso Theu.

"It's solid matter. A thing that you never saw before. That wall of matter is made of a double layer of protons lying one against the other. It absorbs absolutely every and all radiation, and because it is solid matter, not tiny sprinklings of matter in empty space, as is the matter of even the densest star, it stops the triple-ray. That matter is nothing but protons; there are no electrons there, and the positive electrical field is inconceivably great, but it is artificial matter, and that electrical field exerts its strain not in pulling and electrifying other bodies, but in holding space open, in keeping it from closing in about that concentrated matter, just as it does about a single proton, except that here the entire field energy is so absorbed.

"Arcot was tired, and forgot. He turned his magnet and his heat against it. The heat fought the solid matter with the same energy that created it, and with an energy that had resources as great. The magnet curved space about it, and about us. The result was the terrific energy release you saw, and the hole in the wall. All Thett couldn't make any impression on it. One of the rays blasted a hole in it," said Morey with a laugh. For he, too, loved this mighty thing, the almost living ideas of his friend's brain.

"But it is as bad as the space defense. It works both ways. We can't send through it but neither can they. Any thing we use that attacks them, attacks it, and so destroys it—and it fights."

"We're worse off than ever!" said Morey gloomily.

"My friend, you, too, are tired. Sleep, sleep soundly, sleep till I call—sleep!" And Morey slept under Zezdon Afthen's will, till Torlos carried him gently to his room. Then Afthen let the sleep relax to a natural one. Wade decided he might as well follow under his own power, for now he knew he was tired, and could not overcome Zezdon Afthen, who was not.

On Thett, the fort was undestroyed, and now floating on its power units in a sea of blazing lava. Within, men were working quickly to install a second set of the new tubes in the molecular motion ray screen, and other men were transmitting the orders of the Sthanto who had come here as the place of actually greatest safety.

"Order all battleships to the nearest power-feed station, and command that all power available be transmitted to the station attacked. I believe it will be this one. There is no limit on the power transmission lines, and we need all possible power," he commanded his son, now in charge of all land and spatial forces.

"And Ranstud, what happened to that molecular ray screen?"

"I do not know. I cannot understand such power.

"But what most worries me is his wall of darkness," said Ranstud seriously.

"But he was forced to retire for all his wall of darkness, as you saw.

"He can maintain it but a short time, and it was full of holes when he fled."

"Old Sthanto is much too confident, I believe," said an assistant working at one of the great boards in the enemy's fort, to one of his friends. "And I think he has lost his science-knowledge. Any power-man could tell what happened. They tried to use their own big rays against us, and their screen stopped them from going out, just as it stopped ours on the way in. Ours had been working at it for seconds, and hadn't bothered them. Then for a bare instant their ray touched it—and they retired. That shield of blackness is absolutely new."

"They have many men on that ship of theirs," replied his friend, helping to lift the three hundred ton load of a vacuum tube into place, "for it is evident that they built new apparatus, and it is evident their ship was increased in size to contain it. Also the nose was repaired. They probably worked under a time field, for they accomplished an impossible amount of work in the period they were gone."

Ranstud had come up behind them, and overheard the later part of this conversation. "And what," he asked suddenly, "did your meters tell you when our ray opened his ship?"

"Councilor of Science-wisdom, they told us that our power diminished, and our generators gave off but little power when his power was exceedingly little, we still had much."

"Have you heard the myth of the source of his power, in the story that he gets it from all the stars of the Island?"

"We have, Great Councilor. And I for one believe it, for he sucked the power from our generators. So might he suck the power from the inconceivably greater generators of the Suns. I believe that we should treat with them, for if they be like the peace-loving fools of Venone, we might win a respite in which to learn their secret."

Ranstud walked away slowly. He agreed, in his heart, but he loved life too well to tell the Sthanto what to do, and he had no intention of sacrificing himself for the possible good of the race.

So they prepared for another attack of the Thought, and waited.

Chapter XXVI MAN, CREATOR AND DESTROYER

"What we must find," said Arcot, between contented puffs, for he had slept well, and his breakfast had been good, "is some weapon which will attack them, but won't attack us. The question is, what is it? And I think, I think—I know." His eyes were dreamy, his thoughts so cryptically abbreviated that not even Morey could follow them.

"Fine—what is it?" asked Morey after vainly striving to deduce some sense from the formulas that were chasing through Arcot's thoughts. Here and there he recognized them: Einstein's energy formula, Planck's quantum formulas, Nitsu Thansi's electron interference formulas, Stebkowfski's proton interference, Williamson's electric field, and his own formulas appeared, and others so abbreviated he could not recognize them.

"Do you remember what Dad said about the way the Thessians made the giant forts out in space—hauled matter from the moon and transformed it to lux and relux. Remember, I said then I thought it might be a ray—but found it wasn't what I thought? I want to to use the ray I was thinking of. The only question in my mind is—what is going to happen to us when I use it?"

"What's the ray?"

"Why is it, Morey, that an electron falls through the different quantum energy levels, falls successively lower and lower till it reaches its 'lowest energy level,' and can radiate no more. Why can't it fill another step, and reach the proton? Why has it no more quanta to release? We know that electrons tend to fall always to lower energy level orbits. Why do they stop?"

"And," said Morey, his own eyes dreamily bright now, "what would happen if it did? If it fell all the way?"

"I cannot follow your thoughts, Earthmen, beyond a glimpse of an explosion. And it seems it is Thett that is exploding, and that Thett is exploding itself. Can you explain?" asked Stel Felso Theu.

"Perhaps—you know that electrons in their planetary orbits, so called, tend to fall away to orbits of lower energy, till they reach the lowest energy orbit, and remain fixed till more energy comes and is absorbed, driving them out again. Now we want to know why they don't fall lower, fall all the way? As a matter of fact, thanks to some work I did last year with disintegrating lead, we do know. And thanks to the absolute stability of artificial matter, we can handle such a condition.

"The thing we are interested in is this: Artificial matter has no tendency to radiate, its electrons have no tendency to fall into the proton, for the matter is created, and remains as it was created. But natural matter does have a tendency to let the electron fall into the proton. A force, the 'lowest energy wall,' over which no electron can jump, caused by the enormous space distorting of the proton's mass and electrical attraction, prevents it. What we want to do is to remove that force, iron it out. Requires inconceivable power to do so in a mass the size of Thett-but then—!

"And here's what will happen: Our wall of protonic material won't be affected by it in the least, because it has no tendency to collapse, as has normal matter, but Thett, beyond the wall, has that tendency, and the ray will release the energy of every planetary electron on Thett, and every planetary electron will take with it the energy of one proton. And it will take about one one-hundred-millionth of a second. Thett will disappear in one instantaneous flash of radiation, radiation in the high cosmics!

"Here's the trouble: Thett represents a mass as great as our sun. And our sun can throw off energy at the present rate of one sol for a period of some ten million million years, three and a half million tons of matter a second for ten million years. If all of that went up in one one-hundred-millionth of a second, how many sols?" asked Morey.

"Too many, is all I can say. Even this ship couldn't maintain its walls of energy against that!" declared Stel Felso Theu, awed by the thought.

"But that same power would be backing this ship, and helping it to support its wall. We would operate from—half a million miles."

"We will. If we are destroyed—so is Thett, and all the worlds of Thett. Let that flood of energy get loose, and everything within a dozen light years will be destroyed. We will have to warn the Venonians, that their people on nearby worlds may escape in the time before the energy reaches them," said Arcot slowly.

The Thought started toward one of the nearer suns, and as it went, Arcot and Morey were busy with the calculators. They finished their work, and started back from that world, having given their message of warning, with the artificial matter constructors. When they reached Thett, less than a quarter of an hour of Thessian time had passed. But, before they reached Thett, Arcot's viewplates were blinded for an instant as a terrific flood of energy struck the artificial matter protectors, and caused them to flame into defense. Thett's satellite was sending its message of instantaneous destruction. That terrific ray had reached it, touched it, and left it a shattered, glowing ball of hydrogen.

"There won't be even that left when we get through with Thett!" said Arcot grimly. The apparatus was finished, and once more they were over the now
