Many people seem to believe that Greenfield Village and the Edison Institute and Museum at Dearborn, with their specimens of earlier type of American life and industry, are just a kind of antiquarian hobby of mine. I do not deny that they have given me a great deal of interest and pleasure. But the project is vastly more than a hobby. It has very definite purposes, and I hope will have results lasting down the years. One purpose is to remind the public who visit it and sometimes there are thousands a day–of how farand how fast we have come in technical progress in the last century or so. If we have come so far and so fast, is it likely that we shall stop now?
