2. In general terms, the most important principle of successful teaching is that it should be progressive and adapted in succeeding years to the normal development of the mind of the average child, and this relates to the method of teaching a given subject as well as to the selection of the subjects which shall be taught. 3. Another principle of successful teaching which is of almost as much importance as the one just alluded to is that there shall be one person at the head with a definite plan of work. Applying these principles to Sunday school work, this school supposes that there is certain instruction which properly belongs to the Sunday school to give; that there is no reason why the Sunday school should not make use of the best methods of instruction which are known to educators so far as applicable; and that when the superintendent is elected to his place the church in effect commits to him or her the entire care of that part of the work of the church, and that it is perfectly proper for him to direct his teachers in the work which he will have done in his school during his term of office. PLAN OF ORGANIZATION The school is divided into three departments, Primary, Intermediate, and Senior. The Primary Department keeps the children until the New Year after they are eight years old; the Intermediate takes them through a ten years' course of study, and then the Senior Department receives them into the Bible classes. The Primary Department, which meets in a room by itself and has its own order of exercises, is divided into as many classes with separate teachers as may be necessary for the proper care of its little folks, and all under the care of a superintendent of that department. The usual exercises of this department are of the general character customary in such grades. In July the class which will graduate at the end of the year is formed and placed in the care of a certain teacher, whose special duty is to see that the class is prepared to graduate. The graduating exercises are public, and a neat diploma is presented to each scholar who thus graduates. The Intermediate Department is divided into ten grades, each representing a year of study and each containing two classes, one of boys and one of girls, although there is no reason why boys and girls should not be together in the same class. There is no division of the Senior Department into grades. It contains only three classes, namely, the Young Men's Bible Class, the Young Ladies' Bible Class, and the General Class. COURSES OF STUDY. The principal work of the school is done along the lines of the International Lessons, which are used in all the departments, although the method of teaching them varies in the different grades.
