THE second of the weekly talks relayed from Geneva, where the League of Nations Assembly is now sitting, is being given tonight by the man who has done most for the League idea in Great Britain. As Lord Robert Cecil , he held many high offices in the State— the Ministry of Blockade (1916-18), Assistant Secretaryship of Foreign Affairs (1918), and the Privy Seal (1923-24); and, after he received his peerage, he sat in Mr. Baldwin's Cabinet as Chancellor of the Duchy of Lancaster from 1924 to 1927. He has also been Chancellor of Birmingham University and Rector of Aberdeen. But ever since the League of Nations was established he has given it unremitting service, and his speeches and writings were one of the strongest influences in the acceptance in this country of the new international order.
