The Radcliffe Glee Club operetta, "A Copper Complication," was presented last night in Brattle Hall before a large audience. Altogether, the performance was far above the ordinary college the-atricals, both in the music and the book of the play. Miss Josephine Sherwood and Miss Mabel Daniels carried their parts particularly well. Miss Rebecca Hooper as Charles River acted a man's part very consistently throughout.
