Corridors

The corridors should be wide enough so that the children in passing and repassing will not have to crowd. They should be at least ten feet in width and should be supplied with plenty of doors for exits, ventilation and light and also windows for ventilation and light. When practicable the corridors should be along the north side. This insures sufficient lighting and at the same time does not interfere with the lighting and ventilating of the schoolroom. It is more important that the direct rays of the sun be admitted to the schoolroom than to the corridors.
