TUB TABE MEMORIAL WINDOW 

 On March 23, 1913, a memorial window, by 

 TifEany, was unveiled in Sage Chapel of Cor- 

 nell University. It was given by Mrs. Tarr 

 and accepted, for the university, by acting 

 president T. F. Crane. The presentation and 

 description of the window, by Lawrence Mar- 

 tin, follows. 



This memorial window, dedicated to the late 

 Ealph Stockman Tarr, is given by Mrs. Tarr 

 to Cornell University. Thus the present and 



future generations of Cornell students and of 

 worshipers in this chapel will be reminded of 

 one who was a faithful and inspiring teacher 

 and a great scientist. During the score of 

 years through which he was professor of dy- 

 namic geology and physical geography at Cor- 

 nell University he made a deep impression 

 upon the minds and in the hearts of those of 

 us who were so fortunate as to come in con- 

 tact with him in the home, in the lecture 

 room or laboratory, or in God's great outdoors. 



The memory of Professor Tarr is fresh with 

 all of those present. It is just a year since we 

 were gathered here to pay our last respects at 

 his funeral. Upon this Easter afternoon and 

 in presenting this memorial window I may 

 perhaps be permitted to say briefly some of the 

 things with which all our hearts are filled. 



Professor Tarr's life was a wonderful ex- 

 ample to young men. I may speak of his de- 

 termination to get an education, a determina- 

 tion which led him to enter Harvard Univer- 

 sity and to work his way through college, and, 

 in the early years, even to travel sixty milea 

 each day to and from his recitations while he 

 lived at his parents' home. 



I may speak of his hard work while he was 

 a professor at Cornell, sparing no pains to 

 make his lectures and his laboratory and field 

 work clear, interesting, disciplinary and scien- 

 tifically sound. The hundreds of students who 

 have taken Professor Tarr's courses are the 

 best fruits of this work, for none of them but 

 gained with their knowledge of geology and 

 physical geography a sense of admiration and 

 affection for the teacher. 



I may speak of the imparting of his knowl- 

 edge of the facts of geography to the hundreds 

 of thousands of readers of his books — books 

 which were written with the utmost regard 

 for truth and for the upbuilding of character 

 by the example gained in learning how one's 

 fellow men are utilizing the great resources of 

 the earth and adapting themselves to the di- 

 verse environments in which the Almighty has 

 placed them. 



I may speak of his years of investigation. 

 Professor Tarr was always a student. The 

 success of his teaching and of his writing of
