of getting fundamental truths of sanitary science before his hearers 

 in such an attractive manner that they never forget them. It is 

 the belief of the writer that the work accomplished by Professor 

 Sedgwick along this line is unequaled by that of any other man 

 in this country, either in educational or other lines, and that this 

 fact in a few years will be far more widely realized than at present, 

 when his younger pupils throughout the country reach an age where 

 their work will be felt in the communities in which they live. This 

 influence is already to be found in many unexpected places, and 

 forms a wonderful tribute to the success accomplished by Professor 

 Sedgwick in one of his many lines of usefulness. 



Operation of works. After water-and sewage-purification works- 

 are constructed, it is imperative that they shall be operated in an 

 intelligent and efficient manner. The benefit of this has long been 

 demonstrated in Europe, and the absence of such supervision in 

 many places in America shows the folly of careless and indifferent 

 management. No matter how well water- and sewage-purification 

 works may be designed and built, there is no engineer who can give 

 assurance that the results accomplished will be satisfactory unless 

 the works are well managed. Not only must the works produce 

 a result which is satisfactory from a scientific standpoint, but their 

 behavior should be put before the citizens in a way that will inspire 

 confidence. When fair-minded citizens as a mass continue to lack 

 confidence in works of this type, the latter cannot be called an 

 unqualified success, no matter how fully scientific facts may show 

 their adequacy. 



The Massachusetts Institute of Technology instituted the plan 

 of especially training young men along technical lines, so that they 

 might become competent to serve as superintendents for water and 

 sewage-purification works. In this pioneer work they are entitled 

 to great credit, and their example is already being followed by similar 

 institutions elsewhere. This is an important field of technical 

 education, as a majority of such technically educated men in the 

 future will be connected with the management, rather than with 

 the construction, of works of this type. 



In passing, it may not be amiss to say that the technical managers 

 of works of the type under consideration must have other quali-
