And to-daynot only directly from the primalsource, but from the vast stores ofcondensed sunshine which a generousnature has put by for us, there islight and sunlight in abundance toefficiently illuminate, in the light anddark hours of the day, even the mostremote corners of the workshop, if inthe design and construction of ourbuildings scientific methods are adopt-ed to obtain the most effective orien-tation and mechanical illumination. Good Lighting an Aid to Production It is only within the past few yearsthat illumination has become a spec-ialized branch of industrial engineeringand that foundry and factory execut-ives in general have been forced torecognize the fact, that the instal-lation of properly designed lightingarrangeme
