It affords me great pleasure to write a short preface to this book, since it deals with a matter in which I (in common with all those who are intensely interested in the health of our race) am glad to take an active part. To no woman has it been permitted to do the same amount of good, and to save more misery and suffering, both during and after the war, than to Miss Ettie Rout. Her superhuman energy and indomitable perseverance enabled her to perform, in the most efficient manner possible, a work which few women would care to handle, and of which but an infinitesimally small number are capable. The French Government fully recognised the great services she rendered to the Allies, and did her honour. The book she has written is one of very great value, in that its object is the Health, Happiness, Morality and Well-being of the Community. Not only has Miss Ettie Rout the qualities that characterise all great humanitarians, but she also possesses, in a unique degree, an intimate knowledge of the terrible troubles that arise from irregular intercourse, and of the manner in which they can be reduced and perhaps eliminated. In this book she deals with such simple hygienic measures as are little known in England, though they are in common use in France and in the United States, in both of which countries sound practical common sense prevails. She is persuaded that marriage is the goal to be reached by all, and that everything possible should be done to facilitate it, and so to diminish vice. In her efforts to bring about this happy issue she has the good wishes and congratulations of all who have the health of the community at heart. W.
