4l6 JOHN DANIEL RUNKLE 



The principal events of the period were the unsuccessful ne- 

 gotiations with Harvard University for a union ; the establish- 

 ment of laboratories of mining engineering and metallurgy ; the 

 introduction of shop instruction and the foundation of the School 

 of Mechanic Arts ; the development of professional summer 

 schools in the field ; the beginnings of an engineering labora- 

 tory ; the increased efficiency of military instruction and the 

 summer encampment at Philadelphia in 1876 ; the erection of a 

 gymnasium and the admission of women students. 



Resigning as President in 1878, Dr. Runkle spent the next 

 two years in Europe, and in 1880 resumed his professorship of 

 mathematics. As a teacher he found his highest usefulness and 

 most congenial vocation, a vocation to be happily continued for 

 not fewer than twenty-one years. His teaching was character- 

 ized by stimulating, luminous, unconventional exposition, by 

 quick, incisive questioning, by warm personal interest in his 

 students, and by a constant substratum of uplifting earnestness 

 and dignity. None of his students could fail to acquire ad- 

 miring affection ; very few could withstand the incentive to 

 work. His personal and official relations with his colleagues 

 of the Corporation and Faculty were also most fortunate.
