"You must remember, Walter," he pursued, warming up to his subject, "that it's only within the last ten years or so that we have had the really practical college professor who could do it. The silk-stockinged variety is out of date now. To-day it is the college professor who is the third arbitrator in labour disputes, who reforms our currency, who heads our tariff commissions, and conserves our farms and forests. We have professors of everything-why not professors of crime?" Still, as I shook my head dubiously, he hurried on to clinch his point. "Colleges have gone a long way from the old ideal of pure culture. They have got down to solving the hard facts of life-pretty nearly all, except one. They still treat crime in the old way, study its statistics and pore over its causes and the theories of how it can be prevented. But as for running the criminal himself down, scientifically, relentlessly-bah we haven't made an inch of progress since the hammer and tongs method of your Byrnes."
