To them, sociology sounds like socialism—nothing can sound worse than that—and an institution is where they put Aunt Maggy when she began collecting Wheaties in a stamp album. We can't appeal to them that way. Come on now." I smiled condescendingly, knowing it would irritate him. "What are you doing that's worth anything?" has been using sociological studies of employment, labor and standards of living as a basis for its general policies of—" I stopped him with both raised hands. "Please, Professor Caswell! That would hardly be a recommendation. Washington, the New Deal and the present Administration are somewhat touchy subjects to the men I have money by scholarships and fellowships, and supported their professors and graduate students by research contracts with the government and industry. Caswell had to show a way to make his own department without reference to the needs they were founded to serve." He was becoming flushed with the pleasure of explaining his subject. "All through the ages, it has been a matter of wonder and dismay to men that a simple organization—such as a church to worship in, should go to research fellowships for postgraduate biologists at the university, rather than to a medical foundation." "I see you have your problems, too," Caswell said, conceding me nothing. He extended his hand with a chilly smile. "Well, good afternoon, Mr. Halloway. I'm glad we had this talk." support itself or be cut down to what student tuition pays for, which is a handful of over-crowded courses taught by an assistant lecturer. Caswell had to make it work or get out. But the more I thought about it, the more I wanted to hear what he was going to do for a demonstration. change and rigidity of the unwritten law of styles. "Is it really as simple as that?" I asked. "How about Watashaw? I have some student sociological surveys of it Picture Professor Caswell, head of the Department of Sociology, and with him the President of the University, leaning across the table toward each other, sipping coffee and talking in conspiratorial tones over something they were writing in a notebook. That was us. "Ladies," said the skinny female chairman of the Watashaw Sewing Circle. "Today we have guests." She signaled for us to rise, and we stood up, bowing to polite applause and smiles. "Professor Caswell, and and duties of the clubs of Watashaw." We sat down to another ripple of applause and slightly wider smiles, and then the meeting of the Watashaw Sewing Circle began. In five minutes I began to feel sleepy. There were only about thirty people there, and it was a small room, not the halls of Congress, but they discussed their business of collecting and repairing second hand clothing for charity with the same endless boring parliamentary formality. I pointed out to Caswell the member I thought would be the natural leader, a tall, well-built woman in a green suit, with conscious gestures and a resonant, penetrating voice, and then went into a half doze while Caswell stayed awake beside me and wrote in his notebook. After a while the resonant voice roused me to attention for a moment. It was the tall woman holding the floor over some collective better chance of getting into office than a non-shover?" "I think there's a way they could find for it," Caswell whispered back, and went to work on his equation again. "Yes, several ways to bias the elections." she'd use such methods, but just as an example of the reason why only she admiring remarks about the techniques of clothes repairing, instead of conspiring. After the meeting, Caswell drew the tall woman in the green suit aside and spoke to her confidentially, showing her the diagram of organization we had drawn up. I saw the responsive glitter in the limits and began the climb for University Heights. If Caswell's equations meant anything at all, we had given that sewing circle more growth drives than the Roman Empire. Four months later I had time out from a very busy schedule to wonder how the test was coming along. Passing Caswell's office, I put my head in. He looked up from a student research paper he was correcting. "Caswell, about that sewing club business—I'm beginning to feel the suspense. Could I get an advance report on how it's coming?" "I'm not following it. We're supposed to let it run the full six "Not in the slightest. If you want to graph the membership rise, it should be going up in a log curve, probably doubling every so often." "No, thanks. Could you tell me when she'll be back?" "Not until dinner. She's at the meetin'." "The sewing club?" I asked. "No, sir, not that thing. There isn't any Sewing club any more, not for a long time. She's at the Civic Welfare meeting." Somehow I hadn't expected anything like that. down on top of the graph of membership in the sewing circle. No more members.... Poor Caswell. The bet between us was ironclad. He wouldn't let me back down on it even if I wanted to. He'd probably quit before I put through the first slow move to fire him. His professional pride would Five hours to wait. And what if Caswell asked me what I had found out in the meantime? I didn't want to tell him anything until I had talked it over with that woman Searles first. of enthusiasm and excitement in the air. Someone was making a speech up on the platform. Most of the people there were women. to the civic pride of all citizens of Watashaw. All we need is more members. Now get out there and recruit! seated in a row of chairs, was a group that was probably the board of directors. It was mostly women, and the women began to look vaguely familiar, as if they could be members of the sewing circle. Even at the single glance I had given it, the constitution looked exactly like the one we had given the Watashaw Sewing Circle. All I told Caswell when I got back was that the sewing circle had changed its name and the membership seemed to be rising. Next day, after calling Mrs. Searles, I placed some red stars on my increase in membership simply by amalgamating with all the other types of charity organizations in Watashaw, changing the club name with each was becoming an openly profitable business. Membership was rising more Watashaw Mutual Trade and Civic Development Corporation, and all the Watashaw test. These proofs would fascinate any businessman with the sense to see where his bread was buttered. A businessman is constantly dealing with organizations, including his own, and finding them either inert, cantankerous, or both. Caswell's formula could be a handle to were spectacular. Caswell's formulas were proven to the hilt. After reading the last newspaper reports, I called him up. ! I can use this Watashaw thing to get you so it stops growing for more than two months. It's like the great stock they all knew what would happen if it stopped growing. You remember, we tether and die of old age." "When will that be?" "It can't grow past the female population of the town. There are only so many women in Watashaw, and some of them don't like sewing." The graph on the desk before me began to look sinister. Surely Caswell must have made some provision for— "You underestimate their ingenuity," I said into the phone. "Since they wanted to expand, they didn't stick to sewing. They went from general charity to social welfare schemes to something that's pretty close to an incorporated government. The name is now the Watashaw Mutual Trade growing more rapidly with each increase. so many people in Watashaw. It's a pretty small town." about twelve years. There was a long silence while Caswell probably drew the same graph in his own mind. Then he laughed weakly. "Well, you asked me for a demonstration."
