Arthur Zagat - The Golden Age of Science Fiction Volume IX

“Then build ships as big as his, and he’ll quit trying to roast you. Particularly if the inner walls are synthetic plastics. Did you know I used them in the ‘S Doradus’ and ‘Cepheid’?”

“Yes. Were you thinking of that?”

“No—just luck—and the fact that they’re light, strong as steel almost, and can be manufactured in forms much more quickly. Only the outer hull is tungsten-beryllium. The advantage in this will be that nearly all the energy will be absorbed outside, and we’ll radiate pretty fast, particularly as that tungsten-beryllium has a high radiation-factor in the long heat range.”

“What does that mean?”

“Well, ordinary polished silver is a mighty poor radiator. Homely example: Try waiting for your coffee to cool if it’s in a polished silver pot. Then try it in a tungsten-beryllium pot. No matter how you polish that tungsten-beryllium, the stuff WILL radiate heat. That’s why an IP ship is always so blamed cold. You know the passenger ships use polished aluminum outer walls. The big help is, that the tungsten-beryllium will throw off the energy pretty fast, and in a big ship, with a whale of a lot of matter to heat, the Strangers will simply give up the idea.”

“Yes, but only two ships in the system compare with them in size.”

“Sorry—but I didn’t build the IP fleet, and there are lots of tungsten and beryllium on Earth. Enough anyway.”

“Will they use that beam on the fort? And can’t we use the thing on them?”

“They won’t and we won’t—though we could. A bank of those new million watt tubes—perhaps a hundred of them—and we’d have a pretty effective heater—but an awful waste of power. I’ve got something better.”

“New?”

“Somewhat. I’ve found out how to make the mirror field in a plate of metal, instead of a block. Come on to the lab, and I’ll show you.”

“What’s the advantage? Oh—weight saved, and silver metal saved.”

“A lot more than that, Mac. Watch.”

At the laboratory, the new apparatus looked immensely lighter and simpler than the old. The atostor, the ionizer, and the twin ion-projectors were as before, great, rigid, metal structures that would maintain the meeting point of the ions with inflexible exactitude under any acceleration strains. But now, instead of the heavy silver block in which a mirror was figured, the mirror consisted of a polished silver plate, parabolic to be sure, but little more than a half-inch in thickness. It was mounted in a framework of complex, stout metal braces.

Kendall started the ion-flame at low intensity, so the UV beam was little more than a spotlight.

“You missed the point, Mac. Now—watch that tungsten-beryllium plate. I’ll hold the power steady. It’s an eighteen-inch beam—and now the energy is just sufficient to heat that tungsten plate to bright red. But—”

Kendall turned over a small rheostat control—and abruptly the eighteen-inch diameter spot on the tungsten-beryllium plate began contracting; it contracted till it was a blazing, sparkling spot of molten incandescence less than an inch across!

“That’s the advantage of focus. At this distance of a few hundred feet with a small beam I can do that. With a twenty-foot beam, I can get a two-foot spot at a distance of nearly ten miles! That means that the receiving end will have the pleasure of handling one hundred times the energy concentration. That would punch a hole through most anything. All you have to do is focus it. The trouble being, if it’s out of focus the advantage is more than lost. So if there’s any question about getting the focus, we’ll get along without it.”

“A real help, if you do. That would punch a hole before the Stranger ship could turn away as they do now.”

Kendall nodded. “That’s what I was after. It is mainly for the forts, though. We’ll have to signal the dope to the Mars Center and Deenmor stations. They can fix it up, themselves. In the meantime—all we can do is hold on and hunt, and let’s hope better than the Strangers do.”

Sadly the convalescent Gresth Gkae listened to the reports of his lieutenants. More and more disgraced he felt as he realized how badly he had blundered in reporting the people of this system unable to cope with the attackers’ weapons. Gresth Gkae looked up at his old friend and physician, Merth Skahl. He shook his head slowly. “I’m afraid, Merth Skahl. I am afraid. We have, perhaps, made a mistake. The better and the stronger alone should rule. Aye, but is the stronger always the better? I am afraid we have mistaken the Truth in assuming this. If we have—then may Jarth, Lord of Truth and Wisdom punish us. Mighty Jarth, if I have mistaken in following my judgments, it is not from disobedience, it is lack of Thy knowledge. The strongest—they are not always the better, are they?”

Merth Skahl bent sharply over his friend. “Quiet thyself, Gresth Gkae. You know, and I know, you have done only your best, and surely Jarth himself can ask no better of any one. You must rest, for only by rest can those terrible burns be healed. All your stheen over half the body-area was burned off. You have been delirious for many days.”

“But Merth Skahl, think—have we disobeyed Jarth’s will? It is, we know, his will that only the best and the strongest shall rule—but are the best always the strongest? An imbecile adult could destroy the life of a genius-grade child. The strongest wins, but not the best. Such would not be the will of Jarth. If we be the stronger, and the best, then it is right and just that these strange creatures should be destroyed that we may have a stable world of stable light and heat. But look and see, with what terrible swiftness these strange creatures have learned! May it not be they are the better race—that it is we who are the weaker and the poorer? Can it be that Jarth has brought us together that these people might learn—and destroy us? If they be the stronger, and the better—then may Jarth’s will be done. But we must test our strength to the utmost. I must rise, and go to my laboratory soon. They have set it up?”

“Aye, they have, Gresth Gkae. But remember, the weak and the sick make faults the strong and the well do not. Better that you rest yourself. There is little you can do while your body seeks to recover from these terrible burns.”

“You are wrong, my friend, wrong. Don’t you see that my mind is clear—that it is the mind which must fight in these battles, for surely the man is weak against such things as this infra-X-radiation? Why, I am better able to fight now than are you, for I am a trained fighter of the mind, while you are a trained healer of the body. These strange beings with their stiff arms and legs, their tender skins, and—and their swift minds have fought us all too well. If we must test, let it be a test. I have heard how they so quickly solved the riddle of the crumbling field. That took us longer, and we designed it. The Counsel of Worlds put me in command, let me up, Skahl, I must work.”

Concerned, the physician looked down at him. Finally he spoke again. “No, I will not permit you to leave the hospital-ship. You must stay here, but if, as you have said, the mind is what must fight, then surely you can fight well from here, for your mind is here.”

“No, I cannot, and you well know it. I may shorten my life, but what matter. ‘Death is the end toward which the chemical reaction, Life, tends,’” quoted the scientist. “You know I have left my children—my immortality is assured through them. I can afford to die in peace, if it assures their welfare. Time is precious, and while my mind might work from here, it must have data on which to work. For that, I must go to the laboratories. Help me, Merth Skahl.”
