Bythis he understands that the source of light beequal to ten normal candles at a distance of onemetre. Lights should never, unless very strong, bemore than eight feet above the floor level. Theymay be augmented by prismatic globes which con-centrate and distribute rays very successfully. During the past few years the theory of dif-fused light has prompted reflection to the ceilingand subsequent diffusion to all parts of the room.The amount of light needed for such illuminationcan be judged when it is remembered that theintensity of light diminishes in the ratio of theinverse square of the distance. This diminutiondoes not include two reflections and the possi-bility of imperfect reflecting surfaces. To thepresent time indirect lighting of classrooms ob-tained by diffusing the direct rays upon the ceil-ing of the classroom has been found prohibitivein cost and altogether impractical. 103

It is intended invariably to accom-modate all the pupils of the school at one sitting.The consensus of opinion now favors the groundfloor assembly hall. It can very conveniently beplaced between the two wings of an H-shapedbuilding or form the center section of a schoolbuilt in the shape of an E. The entrances to thegallery are from the second floor. Several advantages are gained by placing theassembly hall on the ground floor. Primarily theassembly hall thus placed is safer in caseof fire danger. Light can be had fromabove and from either side wall. Stair climbingand unnecessary disturbance in gathering classesis avoided. The assembly hall can be built tomeet the needs of the school. It is most conven-ient for evening lectures in which the general pub-lic may partake. The average assembly rooms ha
