A. J. Muste, Dean of Brookwood Labor College and chairman of the Conference for Progressive Labor, will speak tonight at 8 o'clock in the Adams House Upper Common room under the auspices of the Harvard Socialist Club. The title of his speech is "Labor Turns Left" and in it he will attempt to answer the self-imposed question: "With miners in revolt in every field, the American Federation of Labor losing strength steadily, auto workers striving to organize, and unions being smashed daily by the depression, where can labor turn to now?"
