Led by Bishops Frederic Dan Huntington and Henry Codman Potter, the Church Association for the Advancement of the Interests of Labor (CAIL) was formed in 1887 to promote concern in the church for workers in industry. Among its activities, it published the quarterly magazine Hammer and Pen, and in 1890 promoted in Episcopal Churches the first observance of "Labor Sunday"(the Sunday after Labor Day). The Archives' holdings include copies of CAIL scrapbooks from 1887-1921, from originals housed at the Diocese of New York.
