A PLEA FOR THE BROADER EDUCATION 

 OF THE CHEMICAL ENGINEER"- 



It has become my duty, under a provi- 

 sion of the constitution of the American 

 Association for the Advancement of Sci- 

 ence, to mark my retirement from the ofSce 

 of vice-president and chairman of Section 

 C by an address. Sir Boverton Redwood 

 remarked on a recent occasion that such 

 addresses offer an opportunity for the dis- 

 semination, from time to time, of highly 

 specialized information. I might follow 

 this custom and talk to you about one of 

 the chemical industries in which I have 

 specialized, but these subjects are of such 

 limited interest that I shall avoid them and 

 turn to one which appeals to me as being 

 of the greatest importance at the present 

 time, although, at first thought, it may 

 seem to have received sufficient considera- 

 tion of late, in view of the address of my 

 predecessor in office, and many others, on 

 the same and allied subjects. I believe, 

 however, that no apology is necessary for 

 asking your attention to the subject of the 

 education of the chemical engineer, and 

 this will include what he should be in the 

 light of what he will be called upon to do, 

 what characteristics he should possess, how 

 he should be directed and encouraged, what 

 training he should submit himself to in 

 order to meet the demands which will be 

 made upon him, and, finally, how his pro- 

 fession may be raised thereby to the level 

 of the other learned professions such as

 meeting, December 31, 1907.
