The art of drawing lessons is much more simple and easy even for children than most persons think. The only prerequisites for drawing practical lessons are--1. A knowledge of the facts. 2. An accurate perception whether they be good or evil. If the action or precept be good, the practical lesson is but an echo of the fact; if evil, avoid. Imitate the good and shun the evil. For instance: Cain and Abel were industrious; from which we learn the duty to be industrious. Cain and Abel went up to worship God; from which learn to copy their good example in going to worship God. But Cain became angry and slew his brother; from which we draw the lesson of warning and danger. Another important part of a teacher's work may be found in Mr. Fitch's third rule, _i. e._, Every teacher before he leaves the lesson, should carefully call back in a child's own language all that he has taught him. Without this careful, thorough review and _recapitulation_ he cannot be sure that his instructions and the practical lessons taught are really received. A child is, as it were, compelled to remember what he is sure to be called upon for again; so that we can hardly overestimate the value of review and recapitulation. One superintendent in New York recently reviewed, by aid of a blackboard, the whole of John's Gospel with his scholars on two consecutive Sabbaths. The teacher should keep his eyes upon all the class, and address the class generally more than the individual members of the class; but be ready to sympathize with each and all. Never be in a hurry with the lesson; calmly, patiently, candidly proceed. It is far better to get the pupils to _understand_ the first verse or a single thought of the lesson, and proceed no farther, than to hasten over a dozen verses.
