(1) _Study the Field._ The Sunday school must live not in the past, but in the present, with a clear vision of the future. It must not only cherish a loving memory of its field as it has been, but understand thoroughly what it is, and what forces are shaping it for the future. The leaders in each Sunday school working for itself, or preferably those conducting the Sunday schools of a neighborhood working unitedly, should ascertain the nationality, religious condition, and church relations of every family in the district; and not only of every family, of every individual who may have a room in a boarding house. Each political organization knows the residence and party proclivities of every voter in the district; and the churches may learn from the politicians practical lessons upon the best methods of work. (2) _Cultivate the Field._ Since the scholars must come to the school from the population around it, they should be sought, brought in, taught, and evangelized, with all the energy and wisdom which the church possesses. And not only the scholars, but also, in large degree, the teachers must be home-born and home-taught; therefore the Sunday school, to be successful, must train up workers from its own constituency. (3) _Provide for all Elements._ By diligent and constant effort the school should be made representative of all ages, of all classes, of all sections, and as far as practicable of all races found in its community. (4) _Adapt Methods._ If a former constituency has removed from the field, and a new population has surged in, the new element must be looked upon as the constituency of the school. Its needs must be recognized, however different they may be from the needs of the past; and plans must be formed to meet those needs, whatever transformation of the school the new plans may involve.
