PRESENT PROBLEMS 699 



other compound with a much longer name but with no higher destiny 

 than to fill a place in Beilstein. So also in physical chemistry. A 

 careful, painstaking investigation of some of our already established 

 industrial processes with a view to determining the maximum yield 

 at the minimum cost is of the greatest educational value. In other 

 words, a problem for research may have a distinctly practical bearing 

 without being any the less a study in pure science, or without having 

 thereby an inferior educational value. 



In other problems, we have noted, the solution largely depends 

 upon the process, not the reaction. This demands the chemical 

 engineer, a man who combines a broad knowledge of chemistry with 

 the essentials of mechanical engineering. He must be well schooled 

 in the economics of chemistry; have a knowledge of the strength 

 and chemical resistance of materials; be able to design and operate 

 the mechanical means for carrying out on a commercial scale the 

 reactions discovered, and duplicating the conditions already deter- 

 mined. 



All this training cannot be combined in the one man who takes a 

 four years college course. Either he must study an additional year or 

 two, or he must replace some of his chemical work with mechanical 

 engineering. But such a man must contribute a great share in the 

 ultimate success of chemical industries, for on him depends the solu- 

 tion of the problems comprising the second division of our subject. 



With men whose foundations are thus broadly and deeply laid, 

 anxious to enter the industrial arena, and with a generous appre- 

 ciation of the scientific man on the part of the manufacturer, coupled 

 with a willingness to grant him an adequate return on the money 

 invested in such an education, the problems in technical chemistry 

 of the present must rapidly become the achievements of the past.
