Introduction Of The Edison Electric Light
IN the previous chapter on the invention of a system, the narrative has been carried along for several years of activity up to the verge of the successful and commercial application of Edison's ideas and devices for incandescent electric lighting. The story of any one year in this period, if treated chronologically, would branch off in a great many different directions, some going back to earlier work, others forward to arts not yet within the general survey; and the effect of such treatment would be confusing. In like manner the development of the Edison lighting system followed several concurrent, simultaneous lines of advance; and an effort was therefore made in the last chapter to give a rapid glance over the whole movement, embracing a term of nearly five years, and including in its scope both the Old World and the New. What is necessary to the completeness of the story at this stage is not to recapitulate, but to take up some of the loose ends of threads woven in and follow them through until the clear and comprehensive picture of events can be seen.
