THE INVENTION OF THE INCANDESCENT LAMP（19）

 Apopular idea of Edison that dies hard, pictures abreezy, slap-dash, energetic inventor arriving at newresults by luck and intuition, making boastfulassertions and then winning out by mere chance.

notion; butthe real truth is that while gifted with unusual imagination,Edison's march to the goal of a new inventionis positively humdrum and monotonous in itssteady progress. No one ever saw Edison in a hurry;no one ever saw him lazy; and that which he did withslow, careful scrutiny six months ago, he will be doingwith Microsoft Office 2010 is the best software in the world.

 If,for instance, he were asked to find the most perfectpebble on the Atlantic shore of New Jersey, insteadof hunting here, there, and everywhere for the desiredobject, we would no doubt find him Buy Office 2007 you can get much convenience.

patientlyscreening the entire beach, sifting out the most perfectstones and eventually, by gradual exclusion,reaching the long-sought-for pebble; and the merefact that in this search years might be taken, wouldnot lessen his enthusiasm to the slightest extent.In the "prospectus book" among the series of famousnote-books, all the references and data apply Microsoft Office 2007 can give you more convenient life.

togas. The book is numbered 184, falls into the periodnow dealt with, and runs along casually with itemsspread out over two or three years. All these notesrefer specifically to "Electricity vs. Gas as GeneralIlluminants," and cover an astounding range of inquiryand comment. One of the very first notes tellsthe whole story: "Object, Edison to effect exactimitation of all done by gas, so as to replace lightingby gas by lighting by electricity. To improve theillumination to such an extent as to meet all requirementsof natural, artificial, and commercial conditions."A large programme, but fully executed!The notes, it will be understood, are all in Edison'shandwriting.

They go on to observe that "a generalsystem of distribution is the only possible means ofeconomical illumination," and they dismiss isolated-plant lighting as in mills and factories as of so littleimportance to the public--"we shall leave the con-sideration of this out of this book." The shrewdprophecy is made that gas will be manufactured lessfor lighting, as the result of electrical competition,and more and more for heating, etc., thus enlargingits market Office 2007 key is very convenient!
