some sort of consciousness. Hunger cannot be anything but conscious, and there is no other stimulus to eat but hunger.
“The crystals eat. The extraction of power from food is conscious because it is purposeful, and there can be no purpose without consciousness; similarly the power to work from such derived energy is also purposeful and therefore conscious. The crystals do both. And the crystals can transmit all these abilities to their children, just as we do. For although there would seem to be no reason why they should not continue to grow to gigantic size under favorable conditions—yet they do not. They reach a size beyond which they do not develop.
“Instead, they bud—give birth, in fact—to smaller ones, which increase until they reach the size of the preceding generation. And like the children of man and animals, these younger generations grow on precisely as their progenitors!
“Very well, then—we arrive at the conception of a metallically crystalline being, which by some explosion of the force of evolution has burst from the to us familiar and apparently inert stage into these Things that hold us. And is there any greater difference between the forms with which we are familiar and them than there is between us and the crawling amphibian which is our remote ancestor? Or between that and the amoeba—the little swimming stomach from which it evolved? Or the amoeba and the inert jelly of the Protobion?
“As for what Ventnor calls a group consciousness I would assume that he means a communal intelligence such as that shown by the bees and the ants—that in the case of the former Maeterlinck calls the ‘Spirit of the Hive.’ It is shown in their groupings—just as the geometric arrangement of those groupings shows also clearly their crystalline intelligence.
“I submit that in their rapid coordination either for attack or movement or work without apparent communication having passed between the units, there is nothing more remarkable than the swarming of a hive of bees where also without apparent communication just so many waxmakers, nurses, honey-gatherers, chemists, bread-makers, and all the varied specialists of the hive go with the old queen, leaving behind sufficient number of each class for the needs of the young queen.
“All this apportionment is effected without any means of communication that we recognize. Still it is most obviously intelligent selection. For if it were haphazard all the honeymakers might leave and the hive starve, or all the chemists might go and the food for the young bees not be properly prepared—and so on and so on.”
“But metal,” he muttered, “and conscious. It’s all very well—but where did that consciousness come from? And what is it? And where did they come from? And most of all, why haven’t they overrun the world before this?
“Such development as theirs, such an evolution, presupposes aeons of time—long as it took us to drag up from the lizards. What have they been doing—why haven’t they been ready to strike—if Ventnor’s right—at humanity until now?”
“I don’t know,” I answered, helplessly. “But evolution is not the slow, plodding process that Darwin thought. There seem to be explosions—nature will create a new form almost in a night. Then comes the long ages of development and adjustment, and suddenly another new race appears.
“It might be so of these—some extraordinary conditions that shaped them. Or they might have developed through the ages in spaces within the earth—there’s that incredible abyss we saw that is evidently one of their highways. Or they might have dropped here upon some fragment of a broken world, found in this valley the right conditions and developed in amazing rapidity.13 They’re all possible theories—take your pick.”
“Something’s held them back—and they’re rushing to a climax,” he whispered. “Ventnor’s right about that—I feel it. And what can we do?”
“Go back to their city,” I said. “Go back as he ordered. I believe he knows what he’s talking about. And I believe he’ll be able to help us. It wasn’t just a request he made, nor even an appeal—it was a command.”
“But what can we do—just two men—against these Things?” he groaned.
“Maybe we’ll find out—when we’re back in the city,” I answered.
“Well,” his old reckless cheerfulness came back to him, “in every crisis of this old globe it’s been up to one man to turn the trick. We’re two. And at the worst we can only go down fighting a little before the rest of us. So, after all, whatever the hell, what the hell.”
For a time we were silent.
“Well,” he said at last, “we have to go to the city in the morning.” He laughed. “Sounds as though we were living in the suburbs, somehow, doesn’t it?”
“It can’t be many hours before dawn,” I said. “Turn in for a while, I’ll wake you when I think you’ve slept enough.”
“It doesn’t seem fair,” he protested, but sleepily.
“I’m not sleepy,” I told him; nor was I.
But whether I was or not, I wanted to question Yuruk, uninterrupted and undisturbed.
Drake stretched himself out. When his breathing showed him fast asleep indeed, I slipped over to the black eunuch and crouched, right hand close to the butt of my automatic, facing him.
CHAPTER XVII
YURUK
“Yuruk,” I whispered, “you love us as the wheat field loves the hail; we are as welcome to you as the death cord to the condemned. Lo, a door opened into a land of unpleasant dreams you thought sealed, and we came through. Answer my questions truthfully and it may be that we shall return through that door.”
Interest welled up in the depths of the black eyes.
“There is a way from here,” he muttered. “Nor does it pass through—Them. I can show it to you.”
I had not been blind to the flash of malice, of cunning, that had shot across the wrinkled face.
“Where does that way lead?” I asked. “There were those who sought us; men clad in armor with javelins and arrows. Does your way lead to them, Yuruk?”
For a time he hesitated, the lashless lids half closed.
“Yes,” he said sullenly. “The way leads to them; to their place. But will it not be safer for you there—among your kind?”
“I don’t know that it will,” I answered promptly. “Those who are unlike us smote those who are like us and drove them back when they would have taken and slain us. Why is it not better to remain with them than to go to our kind who would destroy us?”
“They would not,” he said “If you gave them—her.” He thrust a long thumb backward toward sleeping Ruth. “Cherkis would forgive much for her. And why should you not? She is only a woman.”
He spat—in a way that made me want to kill him.
“Besides,” he ended, “have you no arts to amuse him?”
“Cherkis?” I asked.
“Cherkis,” he whined. “Is Yuruk a fool not to know that in the world without, new things have arisen since long ago we fled from Iskander into the secret valley? What have you to beguile Cherkis beyond this woman flesh? Much, I think. Go then to him—unafraid.”
Cherkis? There was a familiar sound to that. Cherkis? Of course—it was the name of Xerxes, the Persian Conqueror, corrupted by time into this—Cherkis. And Iskander? Equally, of course—Alexander. Ventnor had been right.
“Yuruk,” I demanded directly, “is she whom you call goddess—Norhala—of the people of Cherkis?”
“Long ago,” he answered; “long, long ago there was trouble in their city, even in the great dwelling place of Cherkis. I fled with her who was the mother of the goddess. There were twenty of us; and we fled here—by the way which I will
