"Perhaps," replied the Assistant, "we ought to make a secret of the tricks of our own handicraft. However, I will not hide from you one very simple maxim, with the help of which you may do this, and a great deal more than this. Take any subject, a substance, an idea, whatever you like; keep fast hold of it; make yourself thoroughly acquainted with it in all its parts, and then it will be easy for you, in conversation, to find out, with a mass of children, how much about it has already developed itself in them; what requires to be stimulated, what to be directly communicated. The answers to your questions may be as unsatisfactory as they will, they may wander wide of the mark; if you only take care that your counter-question shall draw their thoughts and senses inwards again; if you do not allow yourself to be driven from your own position--the children will at last reflect, comprehend, learn only what the teacher desires them to learn, and the subject will be presented to them in the light in which he wishes them to see it. The greatest mistake which he can make is to allow himself to be run away with from the subject; not to know how to keep fast to the point with which he is engaged. Do you try this on your own account the next time the children come; you will find you will be greatly entertained by it yourself." "That is very good," said Charlotte. "The right method of teaching is the reverse, I see, of what we must do in life. In society we must keep the attention long upon nothing, and in instruction the first commandment is to permit no dissipation of it." "Variety, without dissipation, were the best motto for both teaching and life, if this desirable equipoise were easy to be preserved," said the Assistant; and he was going on further with the subject, when Charlotte called out to him to look again at the children, whose merry troop were at the moment moving across the court. He expressed his satisfaction at seeing them wearing a uniform. "Men," he said, "should wear a uniform from their childhood upwards. They have to accustom themselves to work together; to lose themselves among their equals; to obey in masses, and to work on a large scale. Every kind of uniform, moreover, generates a military habit of thought, and a smart, straight-forward carriage. All boys are born soldiers, whatever you do with them. You have only to watch them at their mock fights and games, their storming parties and scaling parties." "On the other hand, you will not blame me," replied Ottilie, "if I do not insist with my girls on such unity of costume. When I introduce them to you, I hope to gratify you by a parti-colored mixture."
