Paul says: "I had rather speak five words with my understanding, that by _my voice_ I might _teach_ others also, than ten thousand words in an unknown tongue." (1 Cor. xiv. 19.) Be strictly impartial; have no favorites in the school; be tenderly respectful to the weaker ones. Particular care should be taken to preserve order fully until the _close_ of the school, for then it becomes most difficult; and after the school he will retire to his closet and commend his feeble, imperfect labors in prayer to God. He will ask himself the following questions: "Does any child leave me to-day with a clear, simple view of _one truth_ of the gospel of Jesus Christ?" and, "Is it a matter perfectly understood between me and my pupils to-day that I am seeking their conversion to God at _this time_, and under my instructions?" He will then think over the events of the hour, and commence his preparation for his next lesson. During the week the Sabbath-school teacher will find something to do every day. On one evening he will visit an absentee, or look up a new scholar; on another, visit some of the parents; then attend a social meeting, or the teachers' meeting, and on another call to interest one to become a new teacher. He gets one boy a place to work, and another he introduces into the public school; gives his scholars his name and residence on a card, and endeavors in all ways to prove himself to be a warm-hearted, sympathizing Christian friend. The teacher's life is the life of his teaching. His character, manners, habits, dress, and associations, all exert an influence of great power upon his pupils and upon his fellow-teachers; and he will do well to adopt the noble, disinterested Christian motto: "If meat make my brother to offend, I will eat no flesh while the world standeth;" or if the theatre, or dancing, or tobacco, or the wine-cup, or cards, or any minor evil, lessen my influence as a Christian teacher, I will cheerfully abandon them at once and for ever. "Be ye holy in all manner of conversation and godliness." _Examples of Teaching._ In appending some examples or lessons in teaching, I have selected two varieties from the "Gall" or "Lesson System," of which the late James Gall, of Edinburgh, was the author. I have done so, first, because it is a _system_ and conforms to all good rules of teaching; secondly, because, having used it for more than a quarter of a century, I have found it to be of more value to the teacher and interest to the children than any or all others, if varied and _adapted_ with a sound discretion; and, thirdly, because there are more suggestions in it to teachers than any other; in fact, it includes all others. Particular care must be taken not to attempt too much. Never attempt to use the whole _ten_ exercises on any _one_ Sabbath lesson, or pursue the same order. Generally use the catechetical, the explanations, and the lesson every Sabbath. In some lessons five or six can be used. All are suggestive.
