"I consider the book 'What a Young Wife Ought to Know' a wise and safe teacher. It is a careful and delicate presentation of vital truths which have to do with the happiness and welfare of home life." COMMENDED BY EMINENT AMERICAN AUTHORS AND EDITORS MARGARET WARNER MORLEY Author of "The Song of Life," "Life and Love," "The Bee People," etc. "There is an awful need for the book, and it does what it has undertaken to do better than anything of the kind I have ever read. You may rely upon me to make it known wherever I can." ELISABETH ROBINSON SCOVIL Superintendent of the Newport Hospital, and Associate Editor of the Ladies' Home Journal; Author of "The Care of Children," etc. "'What a Young Woman Ought to Know' is characterized by purity of tone and delicacy of treatment. "It is one which a mother can place with confidence in the hands of her daughter.
