Quinine immunization has not been tried out scientifically on 

 a large scale in the United States. Except the work in Bolivar 

 County alluded to, no work for the control of malaria on a large 

 scale has been done in the United States. Under our political 

 organization the United States cannot do work of this kind ex- 

 cept as a demonstration. Demonstrations we have done. Our 

 aim' has been to show communities : 



(1) That control of malaria is feasible. 



(2) That control of malaria is profitable. 



(3) And, finally, how to control malaria. 



When the above is known and really believed they will go to 

 work, each unit for itself, and the problem of malaria control 

 will be in the way of solution. 



Quite a number of demonstrations have been made the past 

 three years. The U. S. Public Health Service makes the malarial 

 survey, plans the work in detail, and supervises it as much as is 

 necessary and possible. The communities mainly bear their own 

 expense, the industrial companies in them being the main factor 

 in this. One State, Virginia, has helped finance demonstrations 

 in her bounds, at Wilson and Emporia. No other State has, so 

 far as I know, done so. The Rockefeller Foundation, through 

 the International Health Commission, has financed two in Arkan- 

 sas. They have all been successful, eminently so, and not costly. 

 They were made to demonstrate the value o:^ anti-mosquito work 

 for the control of malaria in the United States; and, if I am a 

 judge, they have demonstrated it. 



The advantage of a demonstration in a community is that, 

 if it be a real success, it induces other neighboring communities 

 to do likewise, and may lead to a very considerable amount of 

 malaria control work. No community ever abandoned it when 

 once it had felt its benefits. 



In addition tO' the demonstrations spoken of, we have visited 

 many places as consultants, so to speak, making malarial sur- 

 veys — to get a line on the condition of the community and what 

 is needed — ^then giving advice and drawing up plans for the 

 control of mal^^ria, but without following it enough to call it a 

 demonstration Some of these communities do good work ;
