. . . Today will be a gala day for festival goers. The program for this afternoon is most attractive. Miss Florence is sure of a hearty welcome in "Endymion" and Venzano's scena, "Ah che assorta." Mr. Converse will be present to conduct his own symphony. Macdowell's suite No. 1, Op. 32, is down on the program and Vladimir de Pachmann, the famous pianist, completes the afternoon's array of attractions.
