Every state has hospitals for insane, prisons, asylums, the best management of which requires special training and expert knowledge. Our state boards of health should be composed of experts in matters relating to public health. On the state boards of medical examiners one naturally would expect to find expert students of educational questions, able and ready to devise methods of examination in harmony with modern principles of pedagogy. In every city there is a health department of the municipal administration, which is charged with all questions relating to municipal health matters and which, in the larger cities, has developed into a complex organization requiring the highest degree of expert knowledge and training in public health science. Every large city has one or more hospitals for its sick poor, for contagious diseases and the like, and here again the best results are obtained from special training and knowledge.
