Furthermore, the free intercourse and exchange of population between the States have made for unity in the higher education. Methods which have proved successful in one community have been imitated and adopted in others. Experiments tried at Harvard, Yale, Princeton, or Columbia have been repeated in the West and South. Teachers trained in the older colleges have helped to organize and develop the new ones. Nor has this process of assimilation been confined to American ideas and models. European methods have been carefully studied and adapted to the needs and conditions of the United States. I happen to know of a new Institute of Technology which has been recently founded in Texas by a gift of eight millions of dollars. The president-elect is a scientific man who has already studied in France and Germany and achieved distinction in his department. But before he touches the building and organization of his new Institute, he is sent to Europe for a year to see the oldest and the newest and the best that has been done there. In fact, the Republic of Learning to-day is the true Cosmopolis. It knows no barriers of nationality. It seeks truth and wisdom everywhere, and wherever it finds them, it claims them for its own. The spirit of voluntary coöperation for the promotion of the common order, of which I spoke in a previous lecture, has made itself felt in education by the formation of Teachers' Associations in the various States, and groups of States, and by the foundation of the National Educational Association, a voluntary body incorporated in the District of Columbia, "to elevate the character and advance the interests of the profession of teaching, and to promote the cause of education in the United States." Finally, while there is no national centre of authority for education in the United States, there is a strong central force of encouragement and enlightenment. The Federal Government shows its interest in education in several ways: First, in the enormous grants of public lands which it has made from the beginning for the endowment of common schools and higher institutions in the various States. Second, in the control and support of the United States Military Academy at West Point, the Naval Academy at Annapolis, the Indian Schools, the National Museum, and the Congressional Library, and in the provision which it makes for agricultural and mechanical schools in different parts of the country. The annual budget for these purposes runs from twelve to twenty millions of dollars a year.
