placarding of the cars and the warnings posted in conspicuous places no doubt helped greatly, and this method undoubtedly should be continued. As long as theatres are allowed to remain open, speakers may be used to advantage to emphasize important points. The County Medical Societies should be asked to appoint committees for supplying information or for seeing that the information given to the public is authoritative. In large cities committees may be organized among hospital superintendents, so that the heartiest co-operation between health authorities and hospitals will be available. The ever-ready aid of the Red Cross and of every other auxiliary body should be employed to the fullest extent to allay apprehension and relieve suffering. _Summary_ The exact knowledge of the mode of transmission of epidemic influenza is still wanting, but it is known to be spread by contact. Attention should be directed toward every practical means of decreasing the number and intimacy of contacts. Publicity campaigns and other educational measures should be pushed strongly. Health Departments should adopt a policy of preparedness during inter-epidemic times, should make every effort to centralize and standardize their work, and should take steps to obtain sufficient legal backing, so that upon the appearance of the epidemic they can take the lead, speak with authority and enforce their ordinances and measures. The physician’s duty is to inform himself on the value of the various measures, and if he is at odds with the public health methods, he should settle them between epidemics, so that when he is called upon to carry out public health orders he can do it to the letter and without criticism. Laymen should learn that quiet living without violent exercise, the keeping of good hours, the avoidance of public gatherings and of unnecessary exposure is the best policy to pursue during influenza epidemics. They should strictly obey the orders of those who have specialized in the control of epidemics, and all business men must stand ready to help in every possible way and to make their business interests subservient to the public good.
