in its original state. But the synthesizer received it, and hummed and buzzed quietly to itself, and presently the man and woman ate. The synthesizer was not the equivalent of those magnificently complex food-machines which in public dining-halls provide almost every dish the gourmets have ever invented from raw materials. But it did make a palatable meal from the tasteless vegetation of the small planet. Kim said quietly, when they had finished eating, "Now we'll find out for certain what Burt intends to do about us." He grimaced. "He's dangerously intelligent. He underestimated me before. He may consider us dead, or he may overestimate us. I think he'll play it safe. I would, in his place." "What does that mean?" Dona asked wistfully. "We will be able to go to some other planet, won't we, Kim? As if we'd gone in the matter-transmitter in a perfectly normal fashion? Simply to take up residence on another world?" Kim shook his head. "I'm beginning to doubt it," he said slowly. "The discovery that with a bit of hafnium a man can change his psychographic pattern is high explosive. If the Disciplinary Circuit can't pick him out as an individual, any man can defy any government which depends on the Circuit. Which means that no government is safe. I've got to be gotten rid of for the sake of government everywhere in the galaxy." "But they can't touch us here," said Dona. "We're safe now." Kim shook his head. "No. I was too hungry to think, before. We're not safe. I've got to work like the devil. Do you remember your Galactic History? Remember what the Disciplinary Circuit was built up to? Remember the Last War? It's not only the space-ships which went into museums. I'm suddenly scared stiff." He stood up and abruptly began to put on the space-suit again. His face had become haggard. "In the Last War there were no battles, only massacres," he said curtly as he snapped buckles. "There was no victory. They used a beam which was a stepped-up version of the Disciplinary Circuit. They called it a fighting-beam, then, and they thought they could fight with it. But they couldn't. It simply made war impossible. So ultimately they hooded over the projectors of the fighting-beams, and most of them probably fell to rust. But there are some in the museums. If Burt and the others want to play safe, they'll haul those projectors out of the museum and hook them up to find and kill us. And
