xcept for a brief, triumphant glance in Johnson's direction, Burnett gave no further attention to what had happened and plunged immediately into practical matters.

To halt the blind worship of work, the Rites had first to be discredited. And to discredit the Rites, the awe inspired by their infallible performance had to be weakened. The sabotage of the Preliminary had been the first local step in that direction. There had been a few similar, if smaller, episodes, executed by other groups, but they had received as little publicity as possible.

"Johnson, you pulled one so big this time that they can't hide it. Twenty thousand witnesses! When it comes to getting things done you're the best we have!"

The little man grinned. "But you're the one who knows how to pick recruits and organize our concepts. This is how it worked. I re-fed the emptied cryotron memory box of a robot discard with patterns to deal with anything it was likely to encounter in a destruction pile. I kept the absolute-freeze mechanism in working order, but developed a shield that would hide its activity from the best pile detector." He spread a large tissue schematic out on the floor and they all gathered around it to study the details. "Now, the important thing was to have an external element that could resume contact with a wider circuit, which could in turn start meshing with the whole robot mechanism and then through that mechanism into the pile. This little lever made the contact at a pre-fed time."

Miss Wright was enthusiastic. "That contact is half the size of any I've been able to make. It's crucially important," she added to Hart. "A large contact can look suspicious."

While others took miniphotos of the schematic, Hart studied the contact carefully. "I think I can reduce its size by another fifty per cent. Alloys are one of my specialties—when I get a chance to work at them."

"That would be ideal," said Burnett. "Then we could set up many more discarded robots without risk. How long will it take?"

"I can rough it out right now." He scribbled down the necessary formulas and everyone photographed that too.

"Maximum security is now in effect," announced Burnett. "You will destroy your copies as soon as you have transferred them to edible base copies. At the first hint of danger you will consume them. Use home enlargers for study. In no case are you to make permanent blowups that would be difficult to destroy quickly." He considered them sternly. "Remember, you are running a great risk. You're not only opposing the will of the state but the present will of the vast majority of citizens."
