A huge sphere. A ball made out of some strange, silvery metal. It rested on top of the nearer hill. Garth and the girl staggered toward it. Out from it reached twin fingers of light. The streamers touched Garth, they touched the girl. "We're there," Garth sighed. "We've found the place. We've won. We're safe." Yelping with the lust to kill, the men came through the woods, came up the hill. Fingers of light reached out from the sphere. A glowing streamer touched another man. He dropped the rock he was carrying. Another man. He laid down his club. Something rode the streamers of light. A message. It whispered to the men the light touched. Their cries ran into quick silence. They looked at each other, they looked at Garth and the girl with him. Both were leaning against the sphere. They seemed to be drawing strength from it. They were smiling. An awed whisper ran through the men who had so recently been a mob. "What is that thing, that ball?" "Look at the light coming from it!" "Say, I think we were wrong about this fellow, Garth." "When that light touched me, I changed my mind about him." "Let's go see what this is all about." "Come on. Nothing is going to hurt us. I feel it." Slowly, they approached. Anger had already left them. Now fear left them. Only awe remained. Then a voice began to speak. * * * * * Here and there upon this earth are fields where men, looking backward, say, "Here history was made. Because of what happened here, a new world came into being." There is a pass in Greece, a field in France, a backyard in Holland. There are fields in America too. There is a field two million years in the future! * * * * * Dawn world or dusk world? The sun went down the western sky. Its rays were flung over the group clustered around the globe, over the listening men, who stared quickly at each other, then away, then stole a glance at Garth, leaning against that globe. Over the frightened, clinging, awed girls, who listened too. In the air was a voice. It came from the sphere. It went directly to the minds of the listeners, whispered as a thought current in their brains, whispered as a ghost moving among the nerve endings. The voice said: "Thus the human race reached its goal. There were not many of us left, a few hundred only. We had reached the point where mental activity alone interested us.... Then our last genius invented what we can only describe to you as a perfect brain. It was a substance that would absorb and retain mental impulses. It would absorb and retain our mental impulses. In effect, then, it would become us. "That substance is housed in the heart of this sphere.
