 toperiodism— will retire from the|

 years 5 service. ^KS^^^m 



Trained pri- 

 marily in bot- 

 any, geology and 

 pUnt physi- 

 ology, Mr. Allard 

 carried on re- 

 search in a rela- 

 t i v e 1 y narrow 

 field— studies of 

 certain farm 

 crops, an official 

 anno uncement 

 said. i 



"But he IS Mr.- Allard. 



probably best known in scientific 

 circles and among readers of nature; 

 publications," the announcement 

 continued, "for his avocation— na- 

 ture in general. As a naturalist he 

 I had a gift for seeing plants, in- 

 ! sects, animals, and man as parts of 

 I ufe adapting themselves to the 

 physical universe and to each 

 other." 



It was "this fortunate combina- 

 tion of expertness" that led to Mr. 

 Allard* work with Dr. W. W. Gar- 

 ner, then head of the Bureau of 

 Plant Industry, in discovering 25 



years ago the law that the blos- 

 soming and fruiting of plants de- t 

 pends upon the length of day orj 

 night. 



The department said Mr. Allard t 

 had done notable work in tobacco' 

 disease research and in scientific 

 tobacco breeding. His record of 

 published papers covering nearly 50 

 years of research, "shows a marb- 

 ling of naturalist reports of great 

 variety." . 



Mr. Allard was graduated from; 

 the University .of North Carolina. 1 

 He lives at 3000 Seventh street, Ar-j 

 lington. Friends say he plans to 

 continue his studies of nature.
