T.he latter part of May announcements of the 156th Commencement were mailed to alumni. In general the program for this year follows the same sequence as in the last few years, a calendar that apparently meets the demands of the greatest number. It is hoped that this weekend arrangement will make it possible for a large proportion of those remaining to stay for the entire period. The program follows: Friday, June 19 Afternoon Arrival of alumni Afternoon Meeting of the Alumni Council Satin-day.
