Many hundreds of graduates will assemble at special luncheon meetings of Harvard Clubs throughout the country Saturday to listen in by radio on the first alumni open house to be held here since the tercentenary celebration in 1936, the University announced yesterday.

At the Saturday meetings the Harvard Clubs will hear a foreign affairs symposium conducted by three Faculty members, which will be broadcast by station WAAB from 2:30 to 3:30 o'clock. Dr. Roger I. Lee, of Boston, member of the Harvard Corporation, will preside at the symposium, and Professors Samuel H. Cross, William Y. Elliott, and Bruce C. Hopper will speak.

In charge of the arrangements for the open house here, which some 50,000 alumni are expected to attend, is a graduate committee including Governor Leverett Saltonstall '14; Dr. Reginald Fitz, the University Marshal; Arthur T. Lyman '16, of Boston; David M. Little, secretary to the University and Adams House master; and Charles H. Watkins '09, of Winchester, representing the Associated Harvard Clubs.

It was also announced yesterday that for the benefit of the Alumni there will be a special showing of the Harvard-Yale game movies at 11 o'clock Saturday morning in the Geographical Institute. Coach Dick Harlow will speak.
