Doctor Gilman was a director of the Johns Hopkins hospital; a trustee of the Peabody Institute; the Pratt Ubrary, and the Mercantile library of Baltimore. He was appointed a trustee of the Peabody Fund for the promotion of education in the South; he is president of the Slater Fund trustees for the education of the Freedmen; president of the American Oriental society; a vice-president of the Archæological Institute of America. He was also named "officer of public instruction" in France. He was made a member of the Venezuelan Boundary Commission, in 1896-97, of the Commission to draft a new charter for Baltimore, and he has been president of the National Civil Service Association since 1901. The degree of LL.D. was conferred on him by Harvard, 1876; Columbia, 1887; St. John's, Baltimore, 1887; Yale, 1889; University of North Carolina, 1889; and Princeton, 1896.
Many of his addresses on education and history are collected in a volume, "University Problems in the United States," 1898. He also wrote "The Life of James Monroe," 1898. He edited the miscellaneous writings of Francis Lieber, 1881; and of Doctor Joseph P. Thompson, 1884. His addresses as president of the American Social Science Association; on the opening of Sibley college, Cornell; at the opening of Adelbert college on "The Benefit Society Derives from Universities"; and at Harvard on similar themes, are masterly efforts of a mind temperamentally and by experience fitted to deal with them.
In 1902 he resigned the presidency of the Johns Hopkins university. In the same year he was selected as the head of the Carnegie Institute, an endowment of .$10,000,000, the gift of Andrew Carnegie for the promotion of scientific research in its highest forms. President Gilman filled this position for two years, defining the scope, establishing the methods and settling the foundations of the work of the Institute. But at the beginning of the second year he informed the trustees that having passed the age of seventy, he had fully determined to resign the presidency at the expiration of his second year. This he did, in December, 1904, the trustees accepting his resignation with professions of deep regret and high esteem.
Doctor Gilman proposes to give these next years to the carrying out of long-cherished plans for literary work.
His address is 614 Park Avenue, Baltimore, Maryland.
