WHOLE VOL. APPLIED ENTOMOLOGY HOWARD I7I 



Association of Economic Entomologists during a period when it 

 grew rapidly in importance, and was later the President of the Asso- 

 ciation. In 1928 he was transferred from the Bureau of Entomology 

 to the Plant Quarantine and Control Administration with the grade 

 of Principal Entomologist and retained charge of the project of gipsy 

 moth extermination. The research work on the gipsy moth and 

 brown-tail moth was transferred to the Section of Forest Insects 

 of the Bureau of Entomology. 



ADDENDUM : AN INTERESTING COMPARISON 



Dr. Vernon L. Kellogg, a graduate of the Kansas State University, 

 a graduate student at Cornell, and later Professor at Stanford Uni- 

 versity, is a man who has done admirable work in several branches 

 of entomology and who was a very prominent teacher down to the 

 time of the World War. From the standpoint of the entomologists, 

 it is greatly to be regretted that his efforts were diverted from our 

 science at that time ; but as patriotic citizens and as men who ought 

 to be interested broadly in all science, we rejoice in his subsequent 

 career. He was one of Herbert Hoover's righthand men through all 

 the wonderful relief work carried on in Europe, and subsequently 

 became Permanent Secretary of the National Research Council, an 

 organization formed during the war and which has grown in a very 

 wonderful way and now is exerting a great influence in American 

 science. 



In 1925 Doctor Kellogg planned an extensive review of the advance 

 in all branches of science in America during a period of 50 years, and 

 he asked me to write for him in condensed shape something that he 

 might use in regard to entomology. The paragraphs that follow were 

 done at that time and have remained in Doctor Kellogg's hands for 

 nearly five years. He has just written me that his duties have been 

 such that he has not been able to carry out his plan of 1925, and, since 

 the statement is at the same time rather analytical and condensed, it 

 seems appropriate to me that it should be published here. 



American Entomology in Fifty Ye.\rs 



In 1875 there were in America almost no professional entomolo- 

 gists and almost no teachers of entomology. Our knowledge of 

 American insects was mainly due to the work of amateurs, and the 

 collections were practically all the private property of these amateur 

 collectors and workers. A number of men of very different occupa- 

 tions had collections of Coleoptera and Lepidoptera, but the other 

 orders had received comparatively little attention. The American
