brain-boys had turned out for their own amusement. "Relax, Ned," I said. He was still holding the salute. "At ease. You'll get a hernia of your exhaust pipe if you stay so tense. Anyways, I'm just the sergeant here. That's the Chief of Police over there." Ned did an about face and slid over to the Chief with that same greased-lightning motion. The Chief just looked at him like something that sprang out from under the hood of a car, while Ned went through the same report routine. "I wonder if it does anything else beside salute and report," the Chief said while he walked around the robot, looking it over like a dog with a hydrant. "The functions, operations and responsible courses of action open to the Police Experimental Robots are outlined on pages 184 to 213 of the manual." Ned's voice was muffled for a second while he half-dived back into his case and came up with the volume mentioned. "A detailed breakdown of these will also be found on pages 1035 to 1267 inclusive." The Chief, who has trouble reading an entire comic page at one sitting, turned the 6-inch-thick book over in his hands like it would maybe bite him. When he had a rough idea of how much it weighed and a good feel of the binding he threw it on my desk. "Take care of this," he said to me as he headed towards his office. "And the robot, too. Do something with it." The Chief's span of attention never was great and it had been strained to the limit this time. I flipped through the book, wondering. One thing I never have had much to do with is robots, so I know just as much about them as any Joe in the street. Probably less. The book was filled with pages of fine print, fancy mathematics, wiring diagrams and charts in nine colors and that kind of thing. It needed close attention. Which attention I was not prepared to give at the time. The book slid shut and I eyed the newest employee of the city of Nineport. "There is a broom behind the door. Do you know how to use it?" "Yes, sir." "In that case you will sweep out this room, raising as small a cloud of dust as possible at the same time." He did a very neat job of it.
