the paper-carbon filament lamps was furnished by Edison at the earnest solicitation of Mr. Henry Villard for the steamship Columbia, in 1879, and it is amusing to note that Mr. Upton carried the lamps himself to the ship, very tenderly and jealously, like fresh eggs, in a market-garden basket. The installation was most successful. Another pioneer plant was that equipped and started in January, 1881, for Hinds & Ketcham, a New York firm of lithographers and color printers, who had previously been able to work only by day, owing to difficulties in color-printing by artificial light. A year later they said: "It is the best substitute for daylight we have ever known, and almost as cheap." Mr. Edison himself describes various instances in which the demand for isolated plants had to be met: "One night at '65,'" he says, "James Gordon Bennett came in. We were very anxious to get into a printing establishment. I had caused a printer's composing case to be set up with the idea that if we could get editors and publishers in to see it, we should show them the advantages of the electric light. So ultimately Mr. Bennett came, and after seeing the whole operation of everything, he ordered Mr. Howland, general manager of the Herald, to light the newspaper offices up at once with electricity." Another instance of the same kind deals with the introduction of the light for purely social purposes: "While at 65 Fifth Avenue," remarks Mr. Edison, "I got to know Christian Herter, then the largest decorator in the United States. He was a highly intellectual man, and I loved to talk to him. He was always railing against the rich people, for whom he did work, for their poor taste. One day Mr. W. H. Vanderbilt came to '65,' saw the light, and decided that he would have his new house lighted with it. This was one of the big 'box houses' on upper Fifth Avenue. He put the whole matter in the hands of his son-in-law, Mr. H. McK. Twombly, who was then in charge of the telephone department of the Western Union. Twombly closed the contract with us for a plant. Mr. Herter was doing the decoration, and it was extraordinarily fine. After a while we got the engines and boilers and wires all done, and the lights in position, before the house was quite finished, and thought we would have an exhibit of the light. About eight o'clock in the evening we lit up, and it was very good. Mr. Vanderbilt and his wife and some of his daughters came in, and were there a few minutes when a fire occurred. The large picture-gallery was lined with silk cloth interwoven with fine metallic thread. In some manner two wires had got crossed with this tinsel, which became red-hot, and the whole mass was soon afire. I knew what was the matter, and ordered them to run down and shut off. It had not burst into flame, and died out immediately. Mrs. Vanderbilt became hysterical, and wanted to know where it came from. We told her we had the plant in the cellar, and when she learned we had a boiler there
