As a nation, we have no comprehensive health organization. The crying need for one I shall point out in a future article. Our only Federal guardianship is vested in the United States Public Health and Marine Hospital Service, which, by some mystery of governmental construction, got itself placed in the Treasury Department, where it certainly does not belong. It is, with the exception of a few ancient political appointees now relegated to unimportant posts, a highly trained and efficient body of hygienists and medical men, the best of whom have also qualified as diplomats in trying crises. Any germ-beleaguered city may call upon this Service for aid. It is a sort of flying squadron of sanitative defence. When yellow fever broke out in New Orleans, it was the M. H. S. men who, working quietly and inconspicuously with the local volunteers, mapped out the campaign which rid the city of the scourge. In the San Francisco panic eight years ago, when bubonic plague beset the city, it was the Marine Hospital Service which restored confidence: and a Service man has been there ever since as the city's chief adviser. The Federal "surgeons," as they are called, may be in St. Louis helping to check smallpox, or in Seattle, blocking the spread of a plague epidemic, or in Mobile, Alabama, fighting to prevent the establishment of an unnecessary and injurious quarantine against the city by outsiders, because of a few cases of yellow jack; and all the while the Service is studying and planning a mighty "Kriegspiel" against the endemic diseases in their respective strongholds--malaria, typhoid, tuberculosis, and the other needless destroyers of life which we have always with us. In the Marine Hospital Service is the germ of a mighty force for national betterment. [Illustration: DR.
