THE RECENT PROGRESS AND PRESENT 



CONDITIONS OF ECONOMIC 



ENTOMOLOGY' 



Fifty years ago, or even less, a very- 

 satisfactory and comprehensive text-book 

 . or manual of economic zoology could have 

 been contained within the covers of a single 

 volume of reasonable size. So great have 

 been the advances, hovs^ever, of late years, 

 that the books and pamphlets published 

 would in themselves make a small-sized 

 library. The whole civilized world has 

 contributed to the advance of economic 

 zoology, and in its many directions it has 

 greatly improved the condition of the hu- 

 man species. 



It seems to be generally acknowledged 

 that the greatest strides in one of its 

 branches, namely, economic entomology, 

 have been made in America, and therefore 

 it has been thought appropriate at this 

 American meeting to choose an economic 

 entomologist to give the principal address, 

 and to take economic entomology as his 

 particular subject. 



Thirteen years ago, in August, 1894, the 

 present speaker delivered an address as 

 retiring president of the Association of 

 Economic Entomologists, in which he took 

 as his subject, "The Rise and Present Con- 

 dition of Official Economic Entomology." 

 In this address (published in Insect Life, 

 volume 7, pages 55 to 108) the early his- 

 tory of the warfare against insects was 

 briefly discussed, the progress through the 



' Principal address, Section of Economic Zool- 

 ogy, Seventh International Zoological Congress, 

 Boston, August, 1907. Read August 23, 1907.
