At the meeting of the Christian Association this evening, the opportunities which are offered to Harvard men to do missionary and philanthropic work in Boston will be set forth, and the various enterprises of this sort which are carried on by the Christian Association, such as the Sailor Mission and the Chinese Sunday School, will be described by men who have been intimately connected with them. All who desire to associate themselves with any of these branches of mission work will be given an opportunity to signify their preferences at this time. The meeting will be held as usual in Holden Chapel at 6.45; the leader will be W. W. Comfort, Gr., chairman of the City Missions Committee. All members of the University are cordially invited to be present.
