When 300 Massachusetts teachers convene at Harvard today as guests of the Cambridge Union of University Teachers they will be meeting with the blessings of William Green, president of the A.F. of L., of which the C.U.U.T. is an affiliate.

In a letter to Ernest J. Simmons '25, assistant professor of English and C.U.U.T. president, Green wrote, "Be assured of the full support and assistance of the A.F. of L. I express the hope that you may hold a most successful and satisfactory conference."
