Professor Egleston has been all his life in active association with the religious and benevolent work of the Episcopal Church. He became president of the Bible and Common Prayer-Book Society in 1871; was vice-president of the Protestant Episcopal City Mission Society from 1870 to 1897; a trustee of the General Theological Seminary, and a member of the corporation of Trinity Church from 1878. In connection with the last-named body some of his relations have an interest wider than his own denomination, and may fittingly be mentioned in a sketch relating chiefly to his scientific career. Two points may here be noted: the schools among the poorer classes maintained by the Trinity corporation; and the unique jeweled chalice in memory of his wife, presented by him to Trinity Church. Aided and controlled more or less by Trinity corporation, though in different parts of the city and in connection with different Episcopal churches, are now eight schools, with about one thousand pupils. In these are taught careful and scientific methods of training along modern lines, of eye and hand development, hygiene, economy, and thrift, to children and youth of the neediest classes. Already for years much interested in these schools, Professor Egleston has, since his withdrawal from professional activity, given much of his time to their advancement, and has found intense gratification in observing the results of this training among a class of children that, from their general environment, would grow up to be a burden or a menace to the city. The intelligent culture of hand and eye, the mental quickening and moral uplifting, the capacity and purpose of honorable self-support, and the protection from moral and social perils, that are imparted and secured through the agency of these schools, are to him a constant source of enthusiasm.
