THURSDAY noon at the close of the ministerial institute the delegates and visitors at the conference were addressed by Mr. F. E. Cleveland, the secretary of Columbia Polytechnic Institute for the Blind, which is located at 1808 H St., N. W., in this city. For nine years previous to coming to Washington, Mr. Cleveland, who is himself blind, was the secretary of the Board of Education for the Blind in the State of Connecticut. About four years ago he came to Washington, and opened this institution for the special purpose of giving to the adult blind a training which would prepare them for useful service and enable them to be self-supporting. Mr. Cleveland made a brief statement to the conference concerning the condition of the blind and the necessity for such work as he was attempting, and asked for the co-operation of delegates and visitors in his plan for the circulation of a book in behalf of the institute. The cause is a worthy one, the appeal for help was a practical one, and we doubt not that the institute will receive substantial benefit as the result of Mr. Cleveland's visit to the encampment.
