Dirty Windows and Poor Eyes.

The factors largely responsible for poor illumination are small, narrow windows, low power artificial lights placed too far ?rom the point of operation, and neglect of facilities at hand for obtaining light, according to the Pennsylvania Department of Labor and Industry. By this neglect is meant lack of cleanliness. Tins applies first of all to the windows. There is scarcely a single industrial locality which does not contain at least one building, and all too frequently .jsevs era! buildings of the same type. They are built with a supply of window space sufficient to illuminate amply the interior. The dust and dirt accumulated upon them, however, destroy in large proportion their usefulness. The same condition is found in artificial lighting. The electric light bulb, dusty or streaked with dirt, the result of hurried and incomplete attempts at washing, often shaded with a fixture meant to be a reflector, but which in reality is anything but that,, faintly illuminates the work and impairs the health and the ’efficiency of the worker.—Scientific American.
