(3) The campaign of education which should be conducted in con- 
nection with the other work can only be carried on effectively I a 
persons who by training and experience know thoroughly the points 
upon which the system is based. The best work can only be done by 
those who have had experience in similar problems and who are 
familiar with data sufficient to refute such fallacious arguments as 
may be adduced from time to time. 
(4) It is possible that means of control additional to those enu- 
merated in this bulletin may be discovered. The chance of such 
discoveries and the consequent hastening of the work will be in- 
creased if persons trained in entomological work are in charge.
