EDVC.lTWy AXD THE WORLD'S WORK OF 

 TO-DAY.* 



It is a time-honored custom in connec- 

 tion with the commencement exercises of 

 our American colleges to read an address, 

 for the benefit especially of those who are 

 about to pass from the limited duties and 

 responsibilities of studentship to the wider 

 duties and responsibilities of citizenship. 

 An opportunity is thus afforded for some 

 last words of friendly counsel, and for a 

 review of those ancient academic ideals 

 which, while they have animated genera- 

 tion after generation of our predecessors, 

 have survived them all. and are still a 

 source of inspiration to our contemporaries. 

 But appropriate as this sort of baccalau- 

 reate address may have been in the past, 

 it now appeai-s to be somewhat too scholastic 

 for the happy day which marks the end 

 of a college course of study and the joyful 

 entrance of the graduates into the activities 

 of professional and business life. More- 

 over, a just appreciation of good ad\'iee 

 and a generous susceptibility to lofty ideals 

 require a degree of physical comfort and a 

 degree of mental repose rarely attainable 

 in the heat of our average summer day. 

 The solemn lessons of antiquity are losing 

 their force, also, by reason of iteration and 

 reiteration from the commencement plat-
