The Conservation of Natural Conditions. 



The activities of many entomologists are directed toward the 

 destruction of insects on as large a scale as their ingenuity and 

 the material resources at their command will permit. \Yhen 

 the insects so destroyed are operating against human life, health, 

 food, clothing, shelter and enjoyment, we applaud the efforts 

 of our economic colleagues. In earlier days in this country 

 we generally approved of the killing of various reptiles, birds, 

 mammals and men who similarly threatened our lives and our 

 property. Later, a portion at least of the American people 

 recognized that some of these animals, including the human 

 species, were, for various reasons, worth saving, especially in 

 those cases where their destruction touched our personal and 

 financial interests. Similar reasons have very lately led to 

 movements for the conservation of forests. 



It is well worth considering whether many of our interesting 

 insects are not being threatened with extermination as a conse- 

 quence of the destruction of the environment on which their 

 existence depends. The fate of some of the I'ritish butterflies 

 is an indication of what may happen here. Various movements 

 for the conservation of natural conditions are under way, 

 without respect to financial or commercial considerations but 

 with regard 10 our intellectual, recreational, esthetic, moral and 

 spiritual advancement. To all such efforts, the support of ento- 

 mologists should be forthcoming without delay.
