high degree of executive ability. In New Jersey, at least, and it is 

 suspected elsewhere, the form of organization most likely to com- 

 mand public confidence is an unpaid board of the strongest citizens 

 of the area concerned. These men, by reason of their community 

 standing, instantly inspire confidence. They can not be secured on a 

 salary basis because they are already earning many times the sum 

 that an effort of this type could pay them. If they are not, they are 

 not sufficiently alive to head a public effort of this kind. 



The expert knowledge of mosquito problems will normally be fur- 

 nished by an employee operating under the direction of this unpaid 

 controlling board. In many cases the mosquito expert can carry the 

 executive side of the work as well. When such a combination can- 

 not be secured, one man must be selected for his executive ability 

 and another for his knowledge of mosquito problems. Responsibil- 

 ity for results should be fixed upon the executive and he should be 

 allowed the fullest possible freedom in the selection and dismissal 

 of his assistants. 



• The seventh and last general problem is the meeting of invasions 

 of mosquitoes bred outside the area. Ordinarily there will be a 

 strong aversion, on the part of the people living within the area, to 

 the expenditure of local funds outside the area, even if they may 

 expect to profit largely thereby. This will be especially true if the 

 outside areas in question are inhabited by people, whom it seems 

 should be able to take care of such breeding places for their own ben- 

 efit. It is at this point that an authority coming from outside the pro- 

 tected area and areas adjacent thereto should be of service, and such 

 a general organization becomes still more imperative as adjacent lo- 

 cal areas take up the work of mosquito control. This general or- 

 ganization can correlate and supplement efforts, especially if it has 

 funds, in such a way as to eliminate the sources from which mos- 

 quito invasions come, in the shortest possible space of time. In 

 order that the general or correlating organization may be really effec- 

 tive it must have some real power in the conduct of local affairs. 



Mosquito Flight 



The practical work of mosquito control has gone far enough to 

 demonstrate that migrating adults of various species of mosquitoes 

 frequently so complicate the problem of freeing a limited area as to 

 render successful work impossible. This fact, when taken with 

 the further fact that interest in the practical problem of control is
