dustrial uses. In this case again it was not because of exper- 
ience in manufacturing, but because he had become a recog- 
nized authority in the study of rare earths, a phase of research 
which is about as far removed from practical results as can 
well be imagined. 
A man who graduated from our course in chemistry in 1906 
and afterwards took his doctor’s degree at the University of 
Wisconsin, is now State Chemist of the Illinois Food Com- 
mission in Chicago. Every man, woman and child in the State 
is dependent directly, or indirectly upon Dr. Klein for the 
maintenance of proper standards of purity in the food which 
we eat. Many other illustrations might be given of the way in 
which the universities of the country have contributed to the 
development of manufacturing and other interests. It is more 
than a question if the benefits which are derived from this kind 
of work are not very much greater than the benefit which 
accrues to the students who study chemistry in a routine man- 
ner at the university. Some of the men mentioned above 
were among the best teachers whom we have ever had at 
Illinois, and there was a very direct connection between their 
ability in research and their success as teachers.
