 Why doesn't Caswell expect the Watashaw sewing club to grow astronomically?
If they got the idea that sociology professors are giving advice and guidance—No, we have to stick to brass tacks and leave Washington out of this. "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. "They are making a survey of the methods and duties of the clubs of Watashaw." If Caswell's equations meant anything at all, we had given that sewing circle more growth drives than the Roman Empire. If you want to graph the membership rise, it should be going up in a log curve, probably doubling every so often."
 Caswell has underestimated the ingenuity of the club members.
 Caswell has underestimated the female population of Watashaw.  Caswell has underestimated the popularity of sewing.  Caswell has underestimated the ingenuity of the club members.  Caswell thinks only women enjoy sewing.
