That each Light in your home may be better and cheaper! Each new advance in the science of illumination finds quick reflection in the lamps that light your home. For as each new thought or new material or new method of construction is tested and ap proved by the scientists in our Research Labo ratories at Schenectady, it is at once communi cated to our manufacturing centers at Cleveland and Harrison, and to various other makers en titled to receive MAZDA Service. For the mission of MAZDA Service is not only to study and experiment and test such new ideas, but to see that every practical thought is quickly placed at the disposal of the manufactur ers of MAZDA Lamps-so that the lighting of your home may steadily grow better and cheaper. And thus the word MAZDA etched on a lamp is not the name of that lamp, or of a type of construction, but the Mark of this scientific research, assuring you that any lamp so marked embodies the latest advances in the science of incandescent lighting.
