#59. Time.#--The most convenient hour is the best hour. Having discovered that hour, hold to it the year round. Frequent changes will bring disaster. Every hour has its advantages and disadvantages. The morning hour is usually attended by more tardiness of teachers and scholars, but all are fresher. The noon hour will suffer less from tardiness and will have a larger attendance of adults. Discipline will be more of a problem, especially if the school is continued far beyond the dinner time. The afternoon hour has the following advantages: (1) The school does not precede nor follow another service, which is detrimental to both. (2) A completely rounded program can be carried out because the time will be longer. (3) There is opportunity for after-meetings, if desired. Many of the best schools are held in the afternoon. There are the following disadvantages, however: (1) It breaks in upon the Sunday afternoon home life. (2) It prevents the members from working in mission schools, etc. (3) It may interfere with the attendance at the night services. #60. Length of Session.#--The usual session is one hour long, but this is too short to secure the best results. An hour and a quarter is better, and is long enough for a morning or noon school. Under good management, an afternoon school can use an hour and a half to advantage. #61. Program.#--The superintendent should have a written program, and know his ground every step of the way. The pastor and chorister should have copies. So also should every individual participant. The passing from one feature of the program to the next should be done quickly, and, so far as possible, without announcement. #62. How to Begin.#--Be ready. Insist that all officers and teachers shall be ready. Begin exactly on time. Do not wait for anything nor anybody. Be sure all understand the signal for beginning. Give the signal once, _never oftener_. Wait for silence. Do not begin without it. #63. Signals.#--Use the bell sparingly, if at all. For certain signals the bell may be desirable, but never to secure order. A chord on the piano is better than a bell. Piano signals should be arranged so that a signal given in a certain way always means the same thing. The superintendent's rising in his place, or, if standing, simply raising his hand, should be signal enough to secure the attention of any school. It will be, if the school is properly trained, and so seated as to be able to see a signal.
