of a century ago, nearly all of the chemists in the United States 

 were engaged in teaching, while today the majority are un- 

 doubtedly working in industrial lines. 



But it is not merely in the industries that the number of 

 chemists has greatly increased during this period. Thirty years 

 ago very few educational institutions could have been found 

 w^hich had more than three or four chemists on their staff. In 

 the institution with which I am connected, the staff includes more 

 than thirty chenn"sts who are engaged in teaching or research, 

 and I do not think that the institution is unusual in this regard. 



Very large numbers of chemists have also been required in 

 recent years by agricultural experiment stations and by gov- 

 ernment bm-eaus. Since the enactment of the pure-food law 

 especially, the demand for chemists to fill positions in connec- 

 tion with the bureau of chemistry has largely exceeded the 

 supply of suitable men, and during the past summer many of 

 those who have been called upon to answer inquiries for chem- 

 ists to fill positions have been compelled to reply that they had 

 no suitable candidate to recommend.
