Nevertheless, Cramer obeyed; he adjusted a dial, pushed down on a toggle switch, rotated another dial. A voice, tonelessly and tinnily mechanical, issued from a loudspeaker beneath the tube. It repeated the phrase that Carroad had given and that Jane was thinking. It continued the repetition until Cramer, at another fingersnap from Carroad, flicked the toggle switch upward. "As you have just heard," said Carroad triumphantly, "we have converted the waveforms into audible representations of what the subject is thinking." The Secretary's brows rose like two caterpillars facing each other, and he said, "Very impressive." But he managed to give the impression that he was thinking, Is that all? Carroad smiled. He said, "I have much more. Something that, I'm sure, will please you very much. Now, as you know, this machine--my Cervus--is exposing hundreds of deviationists and enemy agents every year. "Yet, this is _nothing_!" He stared fiercely at them, but he had a slight smile on the corners of his lips. Jane, knowing him so well, could feel the radiance of his pride at the fact that the Secretary was leaning forward and his mouth was open. "I say this is nothing! Catching traitors after they have become deviationist is locking the garage after the car has been stolen. What if we had a system of control whereby our citizens would be _unable_ to be anything but unquestioningly loyal to the State?" The Secretary said, "Aah!" "I knew you would be far from indifferent," said Carroad. * * * * * Carroad pointed a finger downwards. Cramer, slowly, his jaws set, twisted the flexible neck of Cervus so that the pronged head pointed directly at Jane's distended stomach. He adjusted controls on the board. Immediately the oscilloscope danced with many intricate figures that were so different from the previous forms that even the untutored eyes of the Secretary could perceive the change. "Citizens," said Carroad, "for some time after we'd discovered the rho waves in the adult and infant, we searched for their presence in the brain of the unborn child. We had no success for a long time. But that was not because the rho waves did not exist in the embryo. No, it was because we did not have delicate enough instruments. However, a few weeks ago, we succeeded in building one. I experimented upon my unborn child, and I detected weak traces of the rho waves. Thus, I demonstrated that the ability to form words is present, though in undeveloped form, even in the eight-month embryo. "You're probably wondering what this means. This knowledge does not enable us to make the infant or the unborn speak any sooner. True. But what it does allow us to do is...."
