Bartle shrugged. Pettigill paused and looked at the watch he carried on a long chain attached to a clasp on his tunic. "A Benz chronometer, given to me by Section Secretary Andrews on the completion of my twenty-five years of service. It's radio-synchronized with the master timepiece in Greenland. It gives me a feeling of close communion with my superiors, if you understand what I mean." Bartle did not. He said, "Am I keeping you from your work? If I am, I believe I can fill in on most of this back at the paper; we have files on the Center's operation." The little man hurriedly put out a hand to restrain Bartle who was easing out of the chair. "Not yet, Mr. Bartle," he said, suddenly much more sober. Then his incongruous pomposity appeared again. "My gracious, no, you aren't keeping me from my work. I just must start the Mid-Lower Echelon tape. It won't take a moment. Tonight, they receive 'Concerto For Ass's Jawbone.' Sounds rather ridiculous, doesn't it? Be that as it may, there is a certain stimulation in its rhythmic cacophony. Aboriginality--yes, I would say it arouses a primitive exaltation." He flicked a switch above the recorder, turned a knob, and pressed the starter button on the machine. The tape began winding slowly from one spool to another. "Is it 'casting'?" Bartle asked. "I don't hear a thing." Pettigill laughed. "My stars, no; you can't hear it. See--" He pointed at a needle doing a staccato dance on the meter face of the machine. "That tells me everything is operating properly. Mass Psych advises us never to listen to 'casts. The selections were designed by them for specific social and intellectual levels. It could cause us to experience a rather severe emotional disturbance." A peculiar look came over Bartle's face. "Is there ever a time when all the machines run at once? That is, when every Echelon home is tuned to the melopsych tapecasts?" Pettigill registered surprise. "Why, certainly, Mr. Bartle. Don't you know Amendment 34206-B specifically states that all Echelon homes must receive music therapy at 2300 hours every night? Of course, different tapes to different homes." "That's what I mean." "Haven't you been abiding by the directive, Mr. Bartle?" "I told you I owed my classification to my father's industry. I am definitely lax in my duties." Pettigill laughed--almost wickedly, Bartle thought. "What I'm getting at, is," Bartle continued, "what if the wrong 'casts were channeled into the various homes?" "I remind you, sir, I am in charge of the Center and have been for thirty years. Not even the slightest mistake of that nature has ever occurred during that time!" "That, I can believe, Pettigill," Bartle said, his voice edged with sarcasm. "But, hypothetically, if it were to happen, what would the reaction be?" The little man fidgeted with his watch chain. Then he leaned close to Bartle and said in a barely audible whisper, "This isn't for publication in your article, is it?"
