This great corporation war was concluded by a treaty (November 10, 1879) in which the Western Union acknowledged that Bell was the inventor, that his patents were valid, and agreed to retire from the telephone business. The Bell Company, on its part, agreed to buy the Western Union Telephone System, to pay the Western Union a royalty of twenty per cent on all telephone rentals, and not to engage in the telegraph business. Had this case been decided against the Bell Company it is almost certain that the telephone would have been smothered in the interest of the telegraph and its development delayed for many years. Soon after the settlement of the Western Union suit, the original group which had created the telephone withdrew from the scene. Bell went back to teaching deaf-mutes. He has since busied himself with the study of airplanes and wireless, and has invented an instrument for transmitting sound by light. The new telephone company offered him $10,000 a year as chief inventor, but he replied that he could not invent to order. Thomas Sanders received somewhat less than $1,000,000 and lost most of it exploiting a Colorado gold mine. Gardiner Hubbard withdrew from business and devoted the last years of his life to the National Geographic Society. Thomas Watson, after retiring from the telephone business, bought a ship-building yard near Boston, which has been successful. In making this settlement with the Western Union, the Bell interests not only eliminated a competitor but gained great material advantages. They took over about 56,000 telephone stations located in 55 cities and towns. They also soon acquired the Western Electric Manufacturing Company, which under the control of the Western Union had developed into an important concern for the manufacture of telephone supplies. Under the management of the Bell Company this corporation, which now has extensive factories in Hawthorne, Ill., produces two-thirds of the world's telephone apparatus. With the Western Electric Vail has realized the fundamental conception underlying his ideal telephone system--the standardization of equipment. For the accomplishment of his idea of a national telephone system, instead of a parochial one, Mr. Vail organized, in 1881, the American Bell Telephone Company, a corporation that really represented the federalization of all the telephone activities of the subsidiary companies. The United States was divided into several sections, in each of which a separate company was organized to develop the telephone possibilities of that particular area. In 1899 the American Telephone and Telegraph Company took over the business and properties of the American Bell Company. The larger corporation built toll lines, connected these smaller systems with one another, and thus made it possible for Washington to talk to New York, New York to Chicago, and ultimately--Boston to San Francisco. An enlightened policy led the Bell Company frequently to establish exchanges in places where
