Annual fall trials for the Harvard University Orchestra, otherwise known at the Pierian Sodality of 1898, will be held tonight and tomorrow night at the Music Building. All trials start at 7.15 o'clock. Since this is the 125th year of the Orchestra, a special concert with the Harvard Glee Club is to be arranged.

In addition to this performance other concerts are being planned at Colby Junior College and also one with the Radcliffe Orchestra. Local programs at the Cantabrigia Club, the Harvard Club of Boston, and the Boston Public Library and a few other trips fill out the rest of the Orchestra calendar.
