A dispensary that treats more patients than it can care for properly is no better than a street-car company that chronically provides too few seats and too many straps. Unless physicians test themselves and their profession by results, we shall be compelled to "municipalize the medical man." Preventable sickness costs too much, causes too much wretchedness, and hampers too many modern educational and industrial activities to be neglected. If the medical profession does not fit itself to serve general interests, then cities, counties, and states will take to themselves the cure as well as the prevention of communicable and other preventable sickness. Human life and public health are more precious than the medical profession, more important even than theories and traditions against public interference in private matters. The unreasoning opposition of medical men to government protection of health, their concentration on cure, and their tardy emphasis on prevention have forced many communities to stumble into the evil practices mentioned in Chapter XVI. Incidentally, the best physicians have learned that the prosperity of their profession increases with every increase in the general standard of living. It is the man in the ten-room house not the man in one room who supports physicians in luxury. It is the healthy man and the healthy community that value efficient medical service. Many American cities maintain dispensaries and hospitals for the poor. Whether they will go to the logical conclusion of engaging physicians to give free treatment to all regardless of income depends largely upon what the next generation of private physicians do. The state already says when a physician's training fits him to practice. It will soon expect him to pass rigid examinations in the social and economic aspects of his profession,--its educational opportunity, vital statistics, sick and death rates. Will it need to municipalize him in order to protect itself? Obviously the teacher or parent should not begin cooperation with physicians by lecturing them or by assuming that they are selfish and unwilling to teach. The best first step is to ask questions that they should be able to answer: What causes cholera morbus or summer complaint? When does milk harm the baby? How can unclean milk be made safe? Whose fault is it that the milk is sold unclean and too warm? What agencies help sick babies? What is the health board doing to teach mothers? Or, if a school physician, the teacher can ask:
