Aim to secure balanced, symmetrical activities for your class. Remember your boy is four-sided, that he is physical, mental, social and religious in his nature. Do not neglect any one side of him, but get the proper agencies to cooperate with you for these ends. _Let the boys do whatever they can. Merely insist on adequate adult supervision_. Above all be patient, practical and business-like and remember that old heads never grow on young shoulders. _The Sunday school Teacher should take his place in the community by the side of the teacher of secular instruction. He is an educator, and is dealing with the most plastic and most valuable asset in the community--boyhood_. Let him take his task seriously, look upon his privilege with a desire to accomplish great things, and always remember that the good of the boy is his ultimate aim.

XX DANGER POINTS A real danger lies in boys' groups which are seemingly organized, yet which really have no organization. A few Bible classes have officers, such as president, secretary, and treasurer, and a few standing committees, all of whom take no real part in the class life, the teacher doing everything himself and attempting to deceive the boys by giving them a show of organization. Such classes are detrimental to the spirit of boys' work, and should not be tolerated. The teacher who cannot retire his leadership to the rear of the class, instead of posing at the front, is another serious damper to organized work with boys in the Sunday school. A leader should have a strong Christian character, have the quality of commanding the respect of boys, have the ability to direct boys in doing things, be keen in his sympathy, have patience and persistence, and be absolutely natural in his bearing. He encourages freedom of thought on the part of the boys, believes that a boy has brains enough of his own to think on any point that may be discussed, is open and above-board in his teaching, has a strong grip upon the practical truths of life, and tries to lead his boys out of doubt and difficulty by the path of service.
