to do a lot with hormones and hard radiation treatment. Especially with hormones. You could shoot a man full of some fluid or another, and do almost anything to his organism. You could induce atavism, regression to some lower form of animal life—a highly speeded up regression. When you did that, naturally the analytical mind, the higher thought centers of a more recent evolutionary development, blanked out and the primal mind took over. The body changed too, considerably. Bowren was changing. Then the pain came and he couldn't think. He felt his mind cringing—giving way before the onslaught of the pain. Dimly he could feel the agony in his limbs, the throbbing of his heart, the fading power of reason. He retched, languished through flaccid minutes. There were recurring spasms of shivering as he rolled his thickened tongue in the arid cavity of his mouth. And then, somewhere, a spark exploded, and drowned him in a pool of streaming flame. Consciousness returned slowly—much as it had gone—in waves of pain. It took a long time. Elements of reason and unreason fusing through distorted nightmares until he was lying there able to remember, able to wonder, able to think. Inside the tiny compartment were supplies. A hypo, glucose, a durolene suit neatly folded which he put on. He gave himself a needle, swallowed the tablets, and waited until energy and a sense of well-being gave him some degree of confidence. It was very still. The ship would be cradled on Mars now. He lay there, relaxing, preparing for the real challenge. He thought of how well the Earth Investigation Committee had planned the whole thing. The last desperate attempt of man to get into space—to Mars—a woman's world. At least it was supposed to be. Whatever it was, it wasn't a man's world. The women didn't want Earth anymore. They had something better. But what? There were other questions, and Bowren's job was to find the answers, remain unobserved and get back aboard this ship. He would then hypo himself again, and when the ship blasted off to Earth, he would go through the same transition all over again. He put on the soft-soled shoes as well as the durolene suit and crawled through the small panel into the big cargo bin. It was empty. Only a dim yellow light shone on the big cargo vices along the curved walls. He climbed the ladders slowly, cautiously, through a gnawing silence
