Excerpt from The Art of Illumination This volume is a study of the utilization of artificial light. It is intended to deal, not with the problem of dis. Tributing i11uminants, but with their application, and treats of the illuminants themselves only in so far as a knowl edge of their peculiarities is necessary to their intelligent use. To compress the subject within reasonable bounds, it has been necessary to discuss general principles rather than concrete examples of artificial lighting. The science of producing light changes rapidly and the apparatus of yesterday may be discarded to-morrow, but the art of employing the materials at hand to produce the required results follows lines which are to a very considerable extent subject to fairly well-defined laws. Sins against these laws are all too common, the more so since artificial light has become relatively cheap and easy of applica tion. If this outline of a complex art shall tend to avert even some of the commoner errors and failures in illumi nation, it will have served its purpose. The author here desires to express his obligations to the beautiful treatise Of M. Allemagne for illustrations Of early fixtures and to numerous friends, notably Mr. Luther Stieringer, for valuable material and suggestions.
