CYRIL GEORGE HOPKINS 



I had a vision which will always be mine. He stood there with bared 

 head and spoke words which thrilled me. Then I began to under- 

 stand as never before. I never pick up that text "Permanent Agri- 

 culture," I never teach a class about soils, without that vision of the 

 man, Dr. Hopkins, like a prophet of old, sending forth his message 

 of "Permanency." A farmer who went with us all the day long 

 made this remark to me, "Dr. Hopkins is worth his weight in gold 

 to the farmers of Illinois." To this I could well agree; and I still 

 believe it." 



FRANK L. BENNETT 

 Former student of Doctor Hopkins 



"Through his death, it is not only that the United States has lost 

 a great scientist, and the University of Illinois has lost a great pro- 

 fessor; but also that the soil fertility has lost its best friend. His 

 work on permanent agriculture, his advocation of the use of lime- 

 stone and rock phosphate, and his successful proof of the inoculation 

 of alfalfa with the nodule germs of melilotus, make me feel that what 

 he did for soil fertility is at least equal to, if not more than, what 

 Dr. T. J. Burrill had done for plant disease. Indeed, he accomplished 

 much, yet much more still we expected from him on account of his 

 scientific genius, his good health, and his age. His death is totally 

 out of our expectation. May God bless his family!" 



S. S. CHEN 

 Former student of Doctor Hopkins 



"Accept my deepest regrets and sympathies on the death of your 

 eminent professor, Dr. Cyril G. Hopkins, whose name will remain 

 immortal to the Greek agronomists for his most useful study. It is 

 undoubtedly the foundation of scientific agronomy in Greece."
