infantile paralysis, even though such 

 claim may appear later to be some- 

 what premature, is another argument 

 for trapping flies, destroying them 

 before the eggs are deposited ; since 

 these eggs lay the foundation for an 

 enormous increase of flies as the 

 warm season progresses and a conse- 

 quent increase in disease. 



That the protection of garbage 

 against flies and the quick disposal of 

 same is most important in a campaign 

 against the insect is shown by a re- 

 port of J. H. Paine on some work 

 along this line. Mr. Paine states a [ 

 (Psyche, Oct., 1912) that 22.4 per 

 cent of immature stage of different 

 flies found in garbage were those of house flies. In other words, 

 garbage exposed for two weeks or longer is a menace to health.
