such regions as afford breeding places for A. febrifer and 
A. maculatus. 
5. Antimalarial measures should be based upon a thorough 
anopheles and malaria survey, and those measures should be 
employed which will best meet the conditions. The best single 
measure is the destruction of. larve of malaria carriers, and in 
this work the breeding places of the stream breeders should 
receive first attention. 
6. Our own experience and that of others in the destruction 
of stream breeders by means of larvicides leads us to believe 
that this measure is a practical one in the Philippines and that 
it is within the means of many malarious communities in the 
Archipelago to reduce the amount of malaria by this measure.
