EDWARD ORTON, EDUCATOR* 

 I RESPOND this afternoon to a summons 

 diflBcult to obey but impossible to deny. I 

 am reluctant to undertake what could be 

 done so much better by others, but it is im- 

 possible for me to decline to join in doing 

 honor to the memory of one whom I so 

 much loved and admired, however feeble 

 and inadequate my words may be. 



My association with Dr. Orton extended 

 through a period of nearly thirty years. 

 Beginning as a casual acquaintance, such 

 as is common among men engaged in the 

 same occupation, it rapidly ripened into a 

 friendship which, happily for me, grew in 

 strength with the years as they passed. 

 My most intimate personal relations with 

 him existed during the earlier years of the 

 Ohio State University, the institution to 

 which he gave so large a share of his life's 

 work, and which to-day makes fitting ac- 

 knowledgment of the value of that work 

 and of the irreparable loss which it has 

 sustained in his death. Of Dr. Orton as 

 one of the most eminent of geologists of his 

 time, of the splendid example which he set 

 in the performance of the duties of plain 

 citizenship, and of the many other striking 

 characteristics of a career which is rarely 

 paralleled, others will speak, and I will re-

 vember 26, 1899. A portrait of Orton was published 

 as a frontispiece to. the issue of Science for Septem- 

 ber 1, 1899.
