Professor Lightning tried everything, but it wasn't any good. "Fame," he said, and Charley pointed out, calmly and reasonably, that the kind of fame he'd get from being an experimental subject was just like being a freak, all over again--except that it would wear off, and then, he asked, where would he be? Professor Lightning talked about Man's Duty to Science, and Charley countered with Science's Duty to Man. Professor Lightning tried friendship, and argument, and even force--but nothing worked. Incredible as it seemed to the professor, Charley was content to remain a freak, an Armless Wonder. More, he seemed to be proud and happy about it. It was too bad that the professor didn't think of the one argument that might have worked. In the long run, it wouldn't have made any difference, perhaps--but it would have cleared matters up, right there and then. Because the one workable argument had a good chance of succeeding. But, then, Professor Lightning really didn't understand carny. He never thought of the one good argument, and after a while he gave up, and went away. Of course, that was several days later. Professor Lightning told Charley that he was leaving for New York, and Charley said: "What? In the middle of the season?" Then he told Wrout, and Wrout screamed and ranted and swore that Professor Lightning would never work in carny again. "I'll have you blacklisted!" he roared. And Professor Lightning shrugged and smiled and went away to pack. He took all his notebooks, and all the cages with little animals in them, and he didn't seem at all disturbed. "I'll find another subject," he told Charley, when he left. "When they find out what I've got, in New York, they'll provide me with subjects by the hundred. I did want to help you ..." "Thanks," Charley said honestly. "... But that's the way things are, I suppose," Professor Lightning said. "Maybe some day you'll realize." Charley shook his head. "I'm afraid not, professor," he said, and Professor Lightning shook Charley's foot, and left, and Charley went back to work in the freak show, and for a while he didn't even think about Professor Lightning. Then, of course, the news began to show up in the Chicago _American_, which Charley got two or three days late because his mother sent it to him by mail. At first Charley didn't realize that Dr. Edmund Charles Schinsake was Professor Lightning, but then the _American_ ran his picture; that was the day Professor Lightning was awarded a medal by the AMA, and Charley felt pleased and happy for the old man. It looked as it he'd got what he wanted. Charley, of course, didn't think much about the professor's "limb regeneration"; he didn't need it, he thought, and he didn't want it, and that was that.
