_General cautions_.

A few miscellaneous suggestions, which we shall include under this head, will conclude this chapter.
(1.) Never do any thing _for_ a scholar, but teach him to do it for himself.

How many cases occur in the schools of our country where the boy brings his slate to the teacher, saying he can not do a certain sum.
The teacher takes the slate and pencil, performs the work in silence, brings the result, and returns the slate to the hands of his pupil, who walks off to his seat, and goes to work on the next example, perfectly satisfied with the manner in which he is passing on.

A man who has not done this a hundred times himself will hardly believe it possible that such a practice can prevail, it is so evidently a mere waste of time both for master and scholar.
(2.) Never get out of patience with dullness.

Perhaps I ought to say, never get out of patience with any thing.
