The boys who pass under their hands are in a pitiful plight. In mathematics and physics especially, these men are bad, for after conducting one class through the text book the teacher can rest his brain and become just as lazy as he likes, and that is often very lazy indeed when a man's brain begins to atrophy, so that many professors actually get the idea strongly fixed in their heads that ' 'once a teacher, always a teacher," regardless of whether their work is productive of real results.
