THE POTENCY OF ENGINEERING SCHOOLS 

 AND THEIR IMPERFECTIONS.* 



It is natural at a time like this to revert 

 ia thought to the teaching of engineering 

 in the technological schools of the country, 

 and to ponder on the influence which this 

 teaching produces upon their pupils and 

 upon the economic welfare of the land. I 

 have assumed that some consideration of 

 this question will interest my audience to- 

 day. A discussion of the potency in the 

 body politic of engineering education is 

 particularly appropriate before the school 

 of applied science located under the inspir- 

 ing heights of your majestic mountains, 

 which afford an unrivaled richness to him 

 who attacks their depths with efforts prop- 

 erly directed by science. Applied science 

 gives you the power of reaching your ore, 

 hoisting, treating and finally smelting it 

 —applied science, which has been taught 



* Address delivered before the School of Ap- 

 plied Science of the University of Colorado on 

 November 14, 1902 on the occasion of the celebra- 

 tion of the quarter centennial anniversary of the 

 University.
