Three concerts in four days are on the docket for the Pierian Sodality of 1808, the University Orchestra, which leaves today for its third annual tour of the South.

First scheduled concert is this Saturday night at Princeton, where the Orchestra, in conjunction with the Princeton Glee Club and the Radcliffe Choral Society, will present an all-Bach program.

The following evening, at Mary Baldwin-College for Women, Staunton, Virginia, the Sodality will present as its main feature Debussy's "Blessed Damozel." Winding up its tour on Wednesday, at Sweet Briar College, Sweet Briar, Virginia, it will join the Sweet Briar and Duke Glee Clubs in a presentation of Handel's "Messiah."

Managers Warren E. Fleischner '42 and Robert Jaffe '44 arranged the trip.
