Behind him as he sat moodily staring at the gigantic Revolving Beryl stood a woman of most striking appearance. Her name was Jaska, and according to ideas of the Days Before the Discovery, she seemed a trifle younger than Sarka. Her hand, unadorned by jewelry of any kind, rested on Sarka's shoulder as he studied the Revolving Beryl, while her eyes, whose lashes, matching her raven hair, were like the wings of tiny blackbirds, noted afresh the wonder of this man. "What is to be done?" she asked him at last, and her voice was like music there in the room where science performed its miracles for Sarka. * * * * * Wearily Sarka turned to face her, and she was struck anew, as she had been down the years since she had known this man, every time their glances met, at the mighty curve of his brow, which rendered insignificant his mouth, his delicate nose of the twitching nostrils, the well-deep eyes of him. "Something must be done," he said gloomily, "and that soon! For, unless the children of men are provided with some manner of territorial expansion, they will destroy one another, only the strongest will survive, and we shall return to the days when the waters covered the earth, and monstrous creatures bellowed from the primeval slime!" "You are working on something?" she asked softly. For a moment he did not answer. While she waited, Jaska peered into the depths of the Revolving Beryl, which represented the earth. It was fifty feet in diameter, and in its curved surface and entrancing depths was mirrored, in this latest development of teleview, all the earth and the doings of its people. But Jaska scarcely saw the fleeting images, the men locked in conflict for the right to live, the screaming, terror-stricken women. This was now a century-old story, and the civilization of Earth had almost reached the breaking point. No, she scarcely saw the things in the Beryl, for she had read the hint of a vast, awesome secret in the eyes of Sarka--and wondered if he dared even tell her. * * * * * "If the people knew," he whispered, "they would do one of two things! They would tear me limb from limb, and hurl the parts of me outward into space forever--or they would demand that I move before I am ready--and cause a catastrophe which could never be rectified; and this grand old Earth of ours would be dead, indeed!" "And this secret of yours?" Jaska now spoke in the sign language which only these two knew, for there were billions of other Revolving Beryls in the world, and words could be heard by universal radio by any who cared to listen. And always, they knew, the legions of enemies of Sarka kept their ears open for words of Sarka which could be twisted around to his undoing.
