3. =His Duties in the School Session.= (1) _Present Early._ He should be at his post, if possible, from twenty minutes to half an hour before the opening of the school. However early he may arrive, he will probably find a group of children there in advance of him; and they will behave better if his eye is on them, especially if his glance is kind, and with it is a hand-shake or a word of recognition. The early superintendent will often be surprised to find how much business in the interest of the school can be transacted before the session. (2) _Open Promptly._ With his program ready, he should begin the session exactly on the minute, and should carry out every item according to the plan. If for any reason the superintendent is not at the desk when the moment for the opening arrives, the associate or first department superintendent should be empowered to call the school to order and begin the opening service. (3) _Conduct Program._ The superintendent should conduct the general program of services; although it is advisable to recognize the associate and others, by calling upon them to take some part in the opening or closing services. A superintendent whose methods were always well chosen was wont once in each month to invite some official or prominent member of the church, who was not an attendant upon the school, to be present, sit upon the platform, and offer the prayer at the opening of the session. This kept the leading members of the church in closer relation to the school. (4) _During the Lesson._ As a general principle, the superintendent should remain at his desk during the lesson period; but to this rule frequent exceptions will be made. The supply of substitutes for absent teachers, and the assignment of new scholars to classes, belong to the field of the associate superintendent. (5) _Lesson Review._ In the Sunday schools which still follow the uniform system of lessons, studying the same portion of Scripture in all, or nearly all, the grades of the school, the superintendent should give a brief practical summing up of the practical points in the lesson; but this review should not exceed five or six minutes in length. If the pastor possesses the gift of terse, crisp speaking, this practical talk may be given by him. In the schools adopting the graded courses of lessons this review should be given in each department by the department superintendent. Here again the adaptation to the point of view and needs of the pupils of each grade can be made much more effective than in the ungraded school. (6) _Closing._ The superintendent should so carry out the program as to close the session at the time appointed. An hour and a quarter is as long as is profitable for the school; and everything that needs to be done can be brought into that space. Often much time is lost by unnecessary delays between the numbers on the program.
