6. The class should be consulted, as far as possible, respecting the subject of study. The teacher should lose no opportunity to evince his respect for their opinions. His difficult questions should be asked generally of the class, while the personal questions should be easy and adapted. He should receive all their answers with an abounding charity and confidence, and make the most of the feeblest responses. A tart reply to a single remark will ofttimes seal the lips and hearts of a whole class. They love confidence, and become afraid to trust a teacher with their stammering, half-uttered, imperfect answers, particularly if he appears more anxious to be smart and witty than to do them good and honor them. Let the lessons be systematic and complete. The teacher should aim to draw out the thoughts of his pupils in an easy way, instead of pouring in his own. "_Thoughts_, not words," should be the class-motto, and none can appreciate them better than young people. Let the illustrations be well-chosen and appropriate. If you strike an important practical question during the lesson, do not leave it until satisfactorily investigated, whether the lesson is covered or not. Let every mind be calm and unembarrassed, so that it will work well; much depends upon the class, as well as upon the capacity of the teacher. "A few pebbles, a piece of leather, and a cord, are in some hands, a more formidable weapon than the sword of a giant, although it be strong as a weaver's beam and keen as a blade of Damascus steel." 7. These young people should be especially induced to look into their own hearts, and study their own mental and moral mechanism. Lead them often to converse about themselves. It has been truly said, that "it is a law of human nature, that man is interested in nothing so much as about himself." Whatever relates to his own personal experience always claims his especial regard. Many quite fail as teachers, as well as preachers, because they are so impersonal.
