As the three walked up the elm avenue there met them a little stream of students with college books, and female students with winged-victory hats, and professors with last year's overcoats. And some went past with a smile and others with a shiver.

"That's Professor Withers," said the president in a sympathetic voice as one of the shivering figures went past; "poor Withers," and he sighed.

"What's wrong with him?" said the Wizard; "is he sick?"

"No, not sick," said the president quietly and sadly, "merely inefficient."

"Inefficient?"

"Unfortunately so. Mind you, I don't mean 'inefficient' in every sense. By no means. If anyone were to come to me and say, 'Boomer, can you put your hand for me on a first-class botanist?' I'd say, 'Take Withers.' I'd say it in a minute." This was true. He would have. In fact, if anyone had made this kind of rash speech, Dr. Boomer would have given away half the professoriate.

"Well, what's wrong with him?" repeated Tomlinson, "I suppose he ain't quite up to the mark in some ways, eh?"

"Precisely," said the president, "not quite up to the mark—a very happy way of putting it. Capax imperii nisi imperasset, as no doubt you are thinking to yourself. The fact is that Withers, though an excellent fellow, can't manage large classes. With small classes he is all right, but with large classes the man is lost. He can't handle them."

"He can't, eh?" said the Wizard.

"No. But what can I do? There he is. I can't dismiss him. I can't pension him. I've no money for it."
