An assembly room, within the meaning of this statute, means a room where the pupils are brought together for the purpose of assemblage on special occasions. Neither a classroom nor a study hall is necessarily an assembly room. In schools having an auditorium, such auditorium is the assembly room contemplated by the statute. In schools having but few classrooms, the room used for general assembly purposes should contain the flag. In schoolhouses having but one room, that room is the assembly room within the meaning of the statute.
