The seventh anniversary of the organization of the Prospect Union will be celebrated in the lecture room of the building this evening at eight o'clock. President Ely of the Union will preside, and there will be addresses from Dr. F. G. Peabody, Mr. Charles W. Birtwell, P. M. Hubbard '98, the treasurer of the Union, and a number of workingmen. Letters will also be read from Professor Norton, Col. Higginson, Mayor Sortwell of Cambridge, and other invited guests. There will be vocal and instrumental music and light refreshments will be served.

President Ely has in preparation a pamphlet which will give a complete account of the history of the Union with a statement of its principles and methods. There will be four leading articles on the following subjects: "The Origin of the Union." by Professor Peabody; "The Union and the University," by G. L. Paine '96; "The Union and the Workingman," by James A. Stinson of the Riverside Press, and "The Principles and Methods of the Union," by President Ely. The publication, which is about forty pages long, will also contain pictures of officers and teachers and exterior and interior views of the building. Friends of the union will be especially interested in photographs of four of the men most connected with founding the institution: Robert M. Lovett '92, George L. Peirce '91, Carlos C. Closson '92, and Louis F. Berry '92.

The success of the union this year is no less than in former years. The membership is about four hundred, and the number of instructors and officers from Harvard is almost sixty. Attendance at classes has been slightly better than usual, and the quality of instruction has improved. In other respects no vital changes have occurred. P. M. Tucker '99, has recently been elected chairman of the lecture committee to arrange lectures for the Wednesday evening meetings.

Members of the University are invited to be present, especially teachers of Prospect Union classes.
