"Okay; then what becomes of the new capacity which is being created by the adding of new workshops and the increased efficiency of the old ones? Is there a corresponding expansion of the apperception centers?" Gus' smiling face suddenly turned serious. There was surprise mingled with respect in his voice as he said: "Now there you've hit upon a funny thing, Aussie. I've been wondering about that myself of late: where does the new capacity go? Even the big shots like Dr. Scriven begin to ask questions about that; they don't seem rightly to know. They must have gotten their wires crossed somewhere; the new capacity is there all right, only it doesn't show up, it sort of evaporates.... Excuse me--" Gus darted off to the front room with a jackrabbitt start. Voices were calling for him and fingers were drumming on the counter with the impatience of thirsty drinkers at a bar: Maintenance engineers, piling in and slapping down their orders for Gus to fill. This was the rush hour; Lee knew that it would be the same in all the tool and spare part distribution centers of The Brain. He probably couldn't talk to Gus again before 2 A.M. Sometimes the ruthlessness with which he exploited the kindness of his little friend made Lee feel pretty bad; but then his hunger for more knowledge always won out over his shame. To sit alone in the semidarkness of this egg-shaped little room with strange and fascinating things to play with as he willed was the fulfillment of a childhood dream. The dream had been of a night in the zoo. All the visitors and all the keepers would be asleep in their beds; he would be all alone with the animals. The light of a full moon would fall through the bars of the cages and he would slip in and play with them. Once they saw that it was only a little boy they would be very friendly; he was convinced of that. The tigers would purr like big contented cats, the sad-eyed chimpanzees would come to shake hands and the lion cubs would tumble all over him.... He felt the same now with all these gadgets and machines. Here they were rendered harmless, nor could he do any harm as experimentally he plugged them in and out, as he pushed buttons and turned dials. This interesting pulsemeter, for instance; the beauty of it was that even with those weak residual currents it gave a semblence of functioning.... * * * * * The switchboard-panel was within Lee's reach. "Let's see what happens," he thought as he switched from main-circuit to main-circuit. "Nervus vagus--nervus trigeminus--nervus opticus."
