With the first of January, 1886, the Unitarian Association established a bureau of information in regard to southern education, of which General J.B.F. Marshall, who had been for many years the treasurer of the Hampton Institute, was made the superintendent. This bureau, during its existence of three years, investigated the claims of various schools, and recommended those most deserving of aid. In 1891 Miss Mabel W. Dillingham and Miss Charlotte R. Thorn, who had been teachers for several years in the Hampton Institute, opened a school for negroes in Calhoun, Ala. Miss Dillingham died in 1894; and she was succeeded by her brother, Rev. Pitt Dillingham, as the principal of the school. The Calhoun School has been supported mostly by Unitarians, and it has been successful in doing a practical and important work. During the first eight years of the Tuskegee Institute it received $5,000 annually from Unitarians, and in more recent years $10,000 annually. This has been given by individuals, churches, and other organizations, but in no sense as a denominational work. Concerning the aid given to the Hampton Institute this statement has been made by the principal: "The Unitarian denomination has had a very important part in the work of Hampton. Our first treasurer was General J.F.B. Marshall, a Unitarian who made it possible for General Armstrong first to gain access to Boston and secure friends there, many of whom have been lifelong contributors to this work. General Marshall came to Hampton in 1872, and for some twelve years took a most important part in building up this institution. He trained young men for the treasurer's office, who still hold important positions in the school, and others who have been sent to various institutions. The home of General and Mrs. Marshall here was of incalculable help in many ways, brightening and cheering the lives of our teachers and students. Unitarians have always had a prominent part in the support of Hampton. Mrs. Mary Hemenway was the largest donor to the Institute during her lifetime. She gave $10,000 for the purchase of our Hemenway Farm, and helped General Armstrong in many ways."[25] [Sidenote: Educational Work for the Indians.]
