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.

But it was not forgotten. The teacher knew perfectly well that the boy
would, before long, be at his old tricks again, and was reserving this
story as the means of turning the whole current of public opinion
against such tricks should they again occur.

One day he came to school, in the afternoon, and found the room filled
with smoke; the doors and windows were all closed, though, as soon as he
came in, some of the boys opened them. He knew by this circumstance,
that it was roguery,
