For the project which Scriven had handed him, this study of the collective brains in insect societies, also involved a comparative study of The Brain's organisms and functionings. Toward this end Lee had been given a pass which allowed him freely to circulate through all the lobes, to enter convolution, any gland during the overhaul period and to ask question of the employees. The privilege was rare and he enjoyed it immensely. So vast was this underground world that even now after months he had not seen the half of it; to him the travels of every new night were fantastic Alice-in-Wonderland adventures. As he now left Apperception 36 through the door which led to the interior, the glideways were already swarming with the maintenance crews en route to their stations. The spectacle was colorful, almost like a St. Patrick's Day parade. Gangs of air conditioners were dressed blue, electricians white, black-light specialists in purple, radionics men in orange. The maintenance engineers of the radioactive pyramidal cells looked like illustrations from the science-fiction magazines, hardly human in their twelve-inch armor or sponge rubber filled with a new inert gas which was supposed to be almost gamma ray proof. All these men were young, were tops in their fields, the pick of American Universities, colleges and the most progressive industries. Carefully selected for family background they had been screened through health and intelligence tests, had been trained in special courses, had been subjected to a five-minute personality analysis by The Brain itself. They constituted what was undoubtedly the finest working team ever assembled, and incidentally they made the little city of Cephalon the socially healthiest community in the United States. In his nightly expeditions over these past months Lee had spoken to a great many of them. As now he joined the line, there were many who hailed the lanky, queer looking man: There comes the ant-man. Hello, Professor. Hello, Aussie. For some reason most of the boys assumed that he was an Australian, perhaps because with his graying mane and his emaciated face he looked like a foreigner to them. This popularity with the younger generation, coming as it did so late and unexpected in his life, made Lee very proud. Those were the kind of Americans he had been secretly longing for in those desert years, hardworking, wide-awake, radiant with life: "They really are the salt of the earth, the hope of the world," he thought. He had passed through the median section of the hemispheres and had reached the point just below the cerebrum. This was a region of cavities, the seats of various glands in the human brain. Some of these had their mechanical counterparts in The Brain, huge storage tanks with an elaborate pumping system which carried their fluid chemicals through the labyrinth of The Brain. But there was one gland which had not been duplicated in The Brain, the pineal gland.
