What is a "grown-up" _teacher_? It is not difficult, certainly, to find some, in every locality, to whom this term could _not_ be applied, with any propriety. They have been engaged for years in the work, and yet they are the merest babes. They have no more skill than when they first took a class in hand. When a boy begins to use a penknife, he is very awkward. He cuts himself about as often as he cuts the stick. After a while, however, he learns to manage the matter better. He finds out how to handle the curious instrument with skill and even with elegance. But you will see teachers, so called, who seem never to make any of this progress in their work. They have no more idea now, than they had when they gave their first lesson, of what they must do to secure attention and silence, how they must manage to keep all the children busy, how to secure good attendance, or study of the lesson, how to gain affection and confidence, how to enforce order and obedience, how to do anything, except to sit, book in hand, and ask the questions one after the other round the class, and see that John, George, and James severally say the answers correctly. This is the idea of teaching with which they begin, and they make no progress towards anything better. They acquire no skill. They make no growth. They are "grown-up" bodily. But in all that pertains to teaching, they are still babes. They whittle as awkwardly and unskilfully as when the delicate instrument was first put into their clumsy fingers. They go on from year to year and learn nothing.
