"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." He then spoke of the proposed Exodus, argued, pleaded, painted a rosy picture of the outer world, of a Sun come back, a world of brightness and life. At the conclusion of his speech a sigh arose from the assembled millions--a sigh of hope, of half belief. Had the vote been taken then the Frozen Gate would have been opened. * * * * * But Senator Mollon was on the rostrum, holding up a square, well manicured hand for attention. In his deep rumbling bass he tore the arguments for the Exodus to shreds. With the whip of fear he drove away hope. "If our savage ancestors lived on the inhospitable outer shell of the earth," he shouted, "is that a reason for our taking that retrograde step? Read your histories. What happened to our neighboring nation of Atlantica only a short 15,000 years ago? They did just as this man is urging--opened their outer gate. It promptly froze open, and liquid air, the remnant of what in primordial days was an outer atmosphere, poured down the tunnels. The whole nation died, and we saved ourselves only by blasting the connecting passages between them and us with fulminite."
