The annual meeting and dinner of the Association of Harvard College Class Secretaries will be held at the Union tonight at 6.30 o'clock. Hon. John D. Long '57, president of the Alumni Association, who was to have been the guest of the Association, will be unable to attend the meeting because of illness. In his stead, however, the Association will entertain Mr. W. R. Thayer '81, editor of the Graduates' Magazine, and Roger Ernst, secretary of the class of 1903. After the business meeting, reports on Commencement Day observances, and the Harvard Union will be delivered by the committees appointed by the Association. The principal topics for discussion will be: Class reports, spreads, and secretaries' work in general. Any class secretary who has not already joined the Association may do so at the dinner. The object of the Association is to bring class secretaries together to afford them an opportunity to help each other, and to discuss points of common interest.
