"I must keep clean for them, and I'm going to do it." A captain of the American Expeditionary Force spoke the words. We were standing together in front of a mantel in an old-fashioned room in an ancient seacoast city of France. On the mantel were the pictures of a woman and four beautiful children. The captain was not a saint; he was entirely too profane to be really good company; but, as he looked into the faces of his wife and babies, he was very intense and determined. There is a question of vital interest to all Americans and particularly to those who have sons in the Expeditionary Forces of the United States, and I went abroad to find the answer to it. Rather, there are two such questions: first, What is the moral character of the American soldier abroad? and, second, What are the American military authorities in France doing to keep the soldier physically competent and morally fit? There have been black rumors abroad. Stories have been told that reflect seriously upon the man in uniform. Leaders in high places have been accused of protecting vice, of allowing what amounts to a segregated district directly behind the lines. The charge was widely circulated in December, 1917, by certain publications, that more than one thousand Americans from a suburban community of the northeastern section of the United States were under guard for drunkenness after their first pay-day in France. Alarming statements have been made concerning venereal diseases. I have found the answers to the questions already stated. 1. I have studied conditions in England, in landing-ports and embarkation-ports, in London and in rest-camps. 2. I have lived in constant contact with five hundred American officers for a period of ten days. 3. I have watched the American soldier in Paris on the street, in the hotel, and in the café. 4. I have conferred with those who have special responsibility for investigating social diseases among men with the colors and for conducting a comprehensive educational campaign to fortify these men against sexual temptations. 5. I have visited hospitals under virtually all conditions as to location and the nature of the diseases treated. 6. I have had interviews with surgeons and other regular army officers. 7. The whole matter has been discussed with a distinguished physician who until recently was the chief health officer of a great American city and a recognized authority on the relation of liquor to vice. This physician is now in the government service in France and is giving special attention to sanitation and hygiene. 8. I have had interviews with General Pershing and several of his staff. 9. I have given particular attention to the French ports where American soldiers disembark, spending several days in each of these cities. On two occasions while I was on the ground as many as fifteen thousand men came ashore from convoys in a single day. These men had their first shore experience after a long and nerve-racking voyage.
