WHOLE VOL. APPLIED ENTOMOLOGY HOWARD 5 



ing together fair statements regarding work in many of the coun- 

 tries, especially possibly of the beginnings. I have gone through much 

 printed matter with the purposes of this volume especially in mind, 

 but there are language difficulties, and many important things are 

 buried in official reports covering other branches of agricultural 

 work. In some countries I have had admirable correspondents who 

 have helped me greatly ; in others I have evidently failed to find just 

 the right man. By this I do not mean alone the man with the requisite 

 knowledge, but the man who would take the time to help me when 

 pressed with other duties. As a result, I fear that I may be thought 

 to slight certain people and certain places. I would do much to avoid 

 this if possible, but the time has come to consult the printer. If I 

 have failed to do justice to certain countries, I will at least have done 

 this much good, namely, to give an added incentive to some resident 

 of such a country to do this narrative of the rise of economic ento- 

 mology as he thinks it should be done. 



Perhaps I should record here the long list of men in other coun- 

 tries who have helped me ; but I have decided not to do so — the list 

 would be too long. I extend to them collectively my deep gratitude, 

 and have thanked them specifically in the sections relating to their 

 respective countries. I must here, however, thank the Imperial Bureau 

 of Entomology. It has helped me very greatly. Its invaluable Rcviezv 

 of Applied Entomology is a publication which helps all of us all over 

 the world. The language difficulties just mentioned vanish before the 

 Bureau's corps of linguists ; and the Director, Doctor Marshall, and 

 his principal assistant. Doctor Neave, are courtesy and helpfulness 

 personified. 



As just indicated, there are several countries which, I realize abun- 

 dantly, are not treated satisfactorily here. I am not satisfied with the 

 apologetic general statement, but may insert individual apologies in 

 places where they will count more. 



And now let us look at the story of the growth of our knowledge 

 of what the British call applied entomology but we in the United 

 States, at least down to the present time, have been calling economic 

 entomology.
