Electricity's strong card is its adaptability. It can go wherever a wire may be carried, and into many places where gas or oil lights would not be safe or practical. The only thing lacking is to make it wireless, and perhaps invention sooner or later will be equal to that demand. Early installations were rather carelessly made, but municipal and underwriters' rules are now so strict that practically all danger of fire has been eliminated. The householder in the country should make sure that the underwriters' prescriptions are fully observed, as his insurance may be affected. In the city, official inspection usually guarantees correct wiring. Probably only in the hall, dining room, and living room will we be greatly concerned with the decorative phase of lighting. Elsewhere the question is largely one of practical use, though considerations of taste are not to be neglected. Careful study should be given to the adaptation of lighting to the future uses of the rooms. This will perhaps avoid the use later of unsightly extension cord, though this avoidance can scarcely be made complete.
