FROM INDIANA SOCIETY OF ENGINEERS. 



By Chas. Brossma:s t :n t . 



Mr. President and Gentlemen' I feel that is is an honor to address 

 your meeting, and am glad to speak a few words of greeting on behalf of 

 the Indiana Engineering Society. 



On your program I notice the names of more than one engineer and 

 subjects relating to engineering work. I feel that the scientist and 

 engineer need no introduction, for they have ever worked either together 

 or in sequence for the betterment of man and civilization. 



On the vital questions relating to the physical development of our 

 vast industrial system the scientist has made the work of the engineer 

 possible. 



The first step belongs to your work. You took the initiative and ad-

 water system becomes clogged with Crenothrix. they cry for the scientist 

 to find the remedy. 



The subject. "The Problem of Sewage Disposal," does not appeal t<> a 

 city until the stench is apparent, then. succor from scientist and engineer 

 is needed. 



Most of the papers to be read, touch upon the betterment of the human 

 race, the conservation of its health, and the country's resources. 



Today Dr. Yon Lendenfeld investigates the organs of flight of the best 

 flyers of the insect orders, Lepidoptera. Hymenoptera and Diptera. The 

 public hears and smiles. 



Tomorrow the Wrights fly for hours in the upper air. The public sees 

 and gasps in wonder and amazement. 



And so the scientist needs be the silent man. Carlyle says : "The 

 noble silent men — scattered here and there — each in his department —
