"The United States spent nine billion dollars last year on the four D's; disease, defect, delinquency, and dependency. Why not eliminate their causes instead of attempting to deal with their effects?" was the statement upon which Mrs. Margaret Sanger based her address at the luncheon at the Liberal Club yesterday.

The dining-room of the club was jammed with the audience of 160 members and guests who assembled to hear Mrs. Sanger speak on birth control. She devoted 40 minutes to a formal plea for her cause and about the same length of time to answering questions.

The force of her arguments was established the most strongly when she declared that in 1924 alone she received 87,000 letters from women of the poorer classes asking for information on birth control, which advice she was unable to impart because of the narrowness of the laws. Birth control clinics in other countries, she said, are declared public utilities; in the United States they are suppressed as public nuisances.
