With the aid of Mr. Francis E. Parker another important work was undertaken by Mr. Peabody. Although Dr. Tuckerman had labored to prevent duplication of charitable gifts and to organize the philanthropies of Boston in an effective manner, with the increase of population the evils he strove to prevent had grown into large proportions. In order to prevent overlapping, imposition, and failure to provide for many who were really needy, but not eager to push their own claims, Mr. Peabody organized the Boston Provident Association in 1851. This society divided the city into small districts, and put each under the supervision of a person who was to examine every case that came before the society within the territory assigned him. The first president of this society was Hon. Samuel A. Eliot, who was a mayor of the city, a representative in the lower house of Congress, and an organizer of many philanthropies. This society was eminently successful in its operations, and did a great amount of good. Its friendly visits to the poor and its judicious methods of procuring the co-operation of many charity workers prepared the way for the introduction, in 1879, of the Associated Charities of Boston, which extended and effectively organized the work begun by Mr. Peabody.[22] Numerous other organizations might be mentioned that have been initiated by Unitarians or largely supported by them.[23] [Sidenote: Humane Treatment of Animals.] The work for the humane treatment of animals was begun, and has been largely carried on, by Unitarians. The founder of the American Society for the Prevention of Cruelty to Animals was Henry Bergh, who was a member of All Souls' Church in New York, under the ministry of Dr. Bellows. In 1865 he began his work in behalf of kindness to animals in New York City, and the society he organized was incorporated April 10, 1866. It was soon engaged in an extensive work. In 1873 Mr. Bergh proceeded to organize branch humane societies; and, as the result of his work, most of the states have legislated for the humane care of animals. A similar work of a Unitarian is that of Mr. George T. Angell in Boston, who in 1868 founded, and has since been the president of, the Massachusetts Society for the Prevention of Cruelty to Animals. In 1889 he became the president of the American Humane Education Society, a position he continues to hold. He is the editor of Our Dumb Animals, and has in many ways been active in the work of the great charity with which he has been connected. [Sidenote: Young Men's Christian Unions.]
