52 DOMINION EXPERIME NTAL FARMS 



In addition to the educational work which is effected 

 through the medium of the daily correspondence, the Dominion 

 Entomologist, the Chief Assistant Entomologist and the other 

 officers of the Division address the annual meetings of different 

 agricultural and horticultural societies in various parts of Canada. 

 In the matter of public health, a campaign is carried on against 

 house-flies, which cause increased mortality from infectious 

 diseases and unsanitary conditions. Colleges, schools and 

 individuals send in collections of insects to be named and the 

 collection in the Division is gradually assuming a national 

 character; it contains not only Canadian insects arranged in 

 their scientific orders, but, in the case of many of the injurious 

 species, their life histories, and specimens of the injuries they 

 cause, are arranged in cases for educational purposes.
