(1.) The teacher should study human nature as it exhibits itself in the school-room, by taking an interest in the sports and enjoyments of the pupils, and connecting, as much as possible, what is interesting and agreeable, with the pursuits of the school, so as to lead the scholars to like the place. An attachment to the institution and to the duties of it, will give the teacher a very strong hold upon the community of mind which exists there.

(2.) Every thing which is unpleasant in the discipline of the school should be attended to, as far as possible, privately. Sometimes it is necessary to bring a case forward in public, for reproof or punishment, but this is seldom. In some schools, it is the custom to postpone cases of discipline, till the close of the day, and then, just before the boys are dismissed at night, all the difficulties are settled. Thus, day after day, the impression which is last made upon their minds, is received from a season of suffering, and terror, and tears.

Now such a practice may be attended with many advantages, but it seems to be, on the whole, unwise. Awing the pupils, by showing them the consequences of doing wrong, should be very seldom resorted to. It is far better to allure them, by showing them the pleasures of doing right. Doing right is pleasant to every body, and no persons are so easily convinced of this, or rather so easily led to see it, as children. Now the true policy is, to let them experience the pleasure of doing their duty, and they will easily be allured to it.

In many cases, where a fault has been publicly committed, it seems, at first view, to be necessary that it should be publicly punished; but the end will, in most cases, be answered, if it is noticed publicly, so that the pupils may know that it received attention, and then the ultimate disposal of the case, may be made a private affair, between the teacher and the individual concerned. If, however, every case of disobedience, or idleness, or disorder, is brought out publicly before the school, so that all witness the teacher's displeasure, and feel the effects of it, (for to witness it, is to feel its most unpleasant effects,) the school becomes, in a short time, hardened to such scenes. Unpleasant associations become connected with the management of the school, and the scholars are prepared to do wrong with less reluctance, since the consequence is only a repetition of what they are obliged to see every day.

Besides, if a boy does something wrong, and you severely reprove him in the presence of his class, you punish the class, almost as much as you do him. In fact, in many cases, you punish them more; for I believe it is almost invariably more unpleasant for a good boy to stand by and listen to rebukes, than for a bad boy to take them. Keep these things, therefore, as much as possible, out of sight. Never bring forward cases of discipline, except on mature deliberation, and for a distinct and well-defined purpose.

(3.) Never bring forward a case of discipline of this kind, unless you are sure that public opinion will go in your favor. If a case comes up, in which the sympathy of the scholars is excited for the criminal, in such a way as to be against yourself, it will always do more harm than good. Now this, unless there is great caution, will often be the case. In fact, it is probable that a very large proportion of the punishments which are ordinarily inflicted in schools, only prepare the way for more offences.

It is, however, possible to bring forward individual cases in such a way, as to produce a very strong moral effect, of the right kind. This is to be done by seizing upon those peculiar emergencies, which will arise in the course of the administration of a school, and which each teacher must watch for, and discover himself. They cannot be pointed out. I may, however, give a clearer idea of what is meant, by such emergencies, by an example. It is a case which actually occurred, as here narrated.

In a school where nearly all the pupils were faithful and docile, there were one or two boys, who were determined to find amusement in those mischievous tricks, so common in schools and colleges. There was one boy in particular, who was the life and soul of all these plans. Devoid of principle, idle as a scholar, morose and sullen in his manners, he was, in every respect, a true specimen of the whole class of mischief-makers, wherever they are to be found. His mischief consisted, as usual, in such exploits as stopping up the keyhole, upsetting the teacher's inkstand, or fixing something to his desk to make a noise, and interrupt the school.

It so happened, that there was a standing feud between the boys of his neighborhood, and those of another, situated a mile or two from it. By his malicious activity, he had stimulated this quarrel to a high pitch, and was very obnoxious to the boys of the other party. One day, when taking a walk, the teacher observed a number of boys with excited looks, and armed with sticks and stones, standing around a shoe-maker's shop, to which his poor pupil had gone for refuge from them. They had got him completely within their power, and were going to wait until he should be wearied with his confinement, and come out, when they were going to inflict upon him the punishment they thought he deserved.

The teacher interfered, and by the united influence of authority, management, and persuasion, succeeded in effecting a rescue. The boy would probably have preferred to owe his safety to any one else, than to the teacher, whom he had so often tried to tease; but he was glad to escape in any way. The teacher said nothing about the subject, and the boy soon supposed it was entirely forgotten.
