That is characteristic of Edison. He was the central figure in the electrical industry, which was then young and enthusiastic. The rank and file of the electrical men could see nothing ahead but electricity, but their leader could see with crystal clearness that no one power could do all the work of the country. I suppose that is why he was the leader.
Such was my first meeting with Edison. I did not see him again until many years after—until our motor had been developed and was in production. He remembered perfectly our first meeting. Since then we have seen each other often. He is one of my closest friends, and we together have swapped many an idea.
His knowledge is almost universal. He is interested in every conceivable subject and he recognizes no limitations. He believes that all things are possible. At the same time he keeps his feet on the ground. He goes forward step by step. He regards "impossible" as a description for that which we have not at the moment the knowledge to achieve. He knows that as we amass knowledge we build the power to overcome the impossible. That is the rational way of doing the "impossible." The irrational way is to make the attempt without the toil of accumulating knowledge. Mr. Edison is only approaching the height of his power. He is the man who is going to show us what chemistry really can do. For he is a real scientist who regards the knowledge for which he is always searching as a tool to shape the progress of the world. He is not the type of scientist who merely stores up knowledge and turns his head into a museum. Edison is easily the world's greatest scientist. I am not sure that he is not also the world's worst business man. He knows almost nothing of business.
John Burroughs was another of those who honoured me with their friendship. I, too, like birds. I like the outdoors. I like to walk across country and jump fences. We have five hundred bird houses on the farm. We call them our bird hotels, and one of them, the Hotel Pontchartrain—a
