"I don't believe there is a 'Sun'," Mollon replied; then, with the candor of one who is perfectly sure of himself, added:
"If Mane were right, I still couldn't permit the Frozen Gate to be opened. I can control the people for their own good, here; it might not be possible Outside."
A deep musical note sounded. Suddenly the myriad inhabitants of Subterranea seemed to be milling around in the room. Actually their bodies were in their dwelling cells, but their telucid images filled the hall. By a simple adjustment of the power circuit, their images, instead of being life size, were made only about an inch high, permitting the accommodation of the entire nation in the hall. Their millions of tiny voices, mingling, made a sighing sound.
Mane rose and stepped forward, raising his hand.
"Citizens of Subterranea," he began in powerful, resonant tones, and then went on to put into his address all the fervor of a lifetime of endeavor. He told them of those times in the dim past when the human race still dwelt on the surface of the earth. Of the Sun that poured out inexhaustible floods of life and light; of the green things that were grown, not only to look at, but for food for all living things before food was made synthetically out of mined chemicals. Of the world overrun by a teeming, happy, dynamic civilization.
"Then something happened. The Sun seemed to give less light, less heat. Perhaps we ran into a cloud of cosmic dust that intercepted the Sun's rays. Perhaps the cause was to be found in some change in the Sun's internal structure. But the effects could not be doubted. Ice began to come down from the poles. Ice barriers higher than the highest towers covered the world, wiping out all life but the most energetic.
"Our ancestors, and many other advanced nations, began to burrow toward the hot interior of the earth. We to-day have no idea of the labor that went into the digging of our underground home. We are becoming degenerate. More and more of us, even those who still use the vita-lights, are becoming pale and flabby. There are hardly enough technies to keep the automatic machinery in order. What will happen when those technies also deteriorate, and lose the will to work? For deteriorate they must, just as Senator Mollon and his still active allies will. Just as I will, if I live long enough. There is a great force that we never know here. It is called the cosmic ray. It never penetrates to our depth. And our vita-lights do not produce it."
