Government Sanitation. — The foregoing para- 

 graphs present only the barest outline of the important 

 subject of insects in relation to disease, and of necessity 

 fail to give anything like an adequate conception of the 

 enormous amount of work that has been, done and is 

 now being carried on in this and other countries. The 

 U. S. Public Health Service, with branch offices in prac- 

 tically every state and city of the Union, not only en- 

 forces quarantine regulations and prevents the spread 

 of disease, but its 4;rained officials are investigating 

 disease-producing organisms and their means of disposal. 

 The United States Department of Agriculture, state 

 agricultural schools, experiment and field stations 

 throughout the country are likewise devoting much of 

 their time and money to the study of disease in both 

 animals and plants. Colleges, public schools, and physi- 

 cians are also playing a prominent part, and together 

 with bulletins, reports, magazine articles and the press 

 are educating and arousing the general public to take 

 an active part in this warfare against insects and disease.
