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?" He glared at me, his white hair bristling and his nostrils dilated like a war horse about to whinny. I can say one thing for them—these scientists and professors always keep themselves well under control. from the shock of being asked to produce something solid for his position, and ran his eyes over the titles of the books that lined his recognize its value." Prof. Caswell smiled back tightly. He knew his department was at stake. The other departments were popular with donors and pulled in gift and industry. Caswell had to show a way to make his own department popular—or else. I couldn't fire him directly, of course, but there are ways of doing it indirectly. He laid down his book and ran a hand over his ruffled hair. "Institutions—organizations, that is—" his voice became more resonant like most professors, when he had to explain something he instinctively slipped into his platform lecture mannerisms, and began to deliver an essay—"have certain tendencies built into the way they 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, or a delegation of weapons to a warrior class merely for defense mathematics, expressing the human factors of intermeshing authority and motives in simple formulas. "By these formulations, it is possible to determine automatically the He looked away from me thoughtfully, picked up the book and began to tap it on the desk again. It had some unreadable title and his name on it in gold letters. I got the distinct impression again that he was repressing an urge to hit me with it. He spoke quietly. "All right, I'll give you a demonstration. Are you "I see you have your problems, too," Caswell said, conceding me Caswell had to make it work or get out. rolling in snow. That was a growth sign. I hadn't expected to understand the equation, but it was almost as clear as a sentence. I was impressed and slightly intimidated by it. He had already explained enough so that I knew that, if he was right, conquests of Alexander and the spread of the smoking habit and the change and rigidity of the unwritten law of styles. "Is it really as simple as that?" I asked. "Go on," I urged. He was deep in the symbology of human motives and the equations of "This demonstration has got to be convincing. We'd better pick a little group that no one in his right mind would expect to grow." "There should be a suitable club—" 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. stood up, bowing to polite applause and smiles. "Professor Caswell, and 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 "I think there's a way they could find for it," Caswell whispered back, can be trusted with initiating the change. Just mention all the personal advantages an unscrupulous person could have." He nodded, keeping a straight and sober face as if we were exchanging 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 woman's eyes and knew she was hooked. If Caswell's equations meant anything at all, we had given that sewing how the test was coming along. Passing Caswell's office, I put my head "Caswell, about that sewing club business—I'm beginning to feel the "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." I grinned. "If it's not rising, you're fired." He grinned back. "If it's not rising, you won't have to fire me—I'll burn my books and shoot myself." 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 be shattered, sunk without a trace. I remembered what he said about shooting himself. It had seemed funny to both of us at the time, And what if Caswell asked me what I had found out in the meantime? I bunting already down on the floor, people holding banners, and plenty of enthusiasm and excitement in the air. Someone was making a speech up on the platform. Most of the people there were women. Everyone's supposed to have it. We've just printed up six thousand copies to make sure there'll be enough to last." The tall woman on the platform had been making a driving, forceful and Secular Charities." That's what it said. Below began the rules of membership. I looked up. The speaker, with a clear, determined voice and conscious, forceful gestures, had entered the homestretch of her speech, an appeal to the civic pride of all citizens of Watashaw. "With a bright and glorious future—potentially without poor and without uncared-for ill—potentially with no ugliness, no vistas which are not beautiful—the best people in the best planned town in the country—the jewel of the United States." She paused and then leaned forward intensely, striking her clenched hand on the speaker's stand with each word for emphasis. " All we need is more members. Now get out there and recruit! " I finally recognized Mrs. Searles, as an answering sudden blast of sound half deafened me. The crowd was chanting at the top of its lungs: "Recruit! Recruit!" Mrs. Searles stood still at the speaker's table and behind her, familiar, as if they could be members of the sewing circle. I put my lips close to the ear of the pretty usher while I turned over some kind of organization song with the tune of "Marching through Georgia." Even at the single glance I had given it, the constitution looked And good prospects full member with its contractual obligations and its lures, if the 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. "Perfect, Wilt, perfect ! I can use this Watashaw thing to get you so well and you're satisfied?" He was definitely putting on a chill. We were friends now, but obviously he was still peeved whenever he was reminded that I had doubted that his theory could work. And he was using its success to rub my nose in the realization that I had been wrong. A man with a string of degrees after his name is just as human as anyone else. I had needled him pretty hard that first time. "I'm satisfied," I acknowledged. "I was wrong. The formulas work beautifully. Come over and see my file of documents on it if you want a boost for your ego. Now let's see the formula for stopping it." He sounded cheerful again. "I didn't complicate that organization with negatives. I wanted it to grow . It falls apart naturally when it stops growing for more than two months. It's like the great stock boom before an economic crash. Everyone in it is prosperous as long as 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 There was a long silence while Caswell probably drew the same graph
