one would examine a vast machine, and to 

 check the speculations suggested by his 

 fancy, by sound common sense and good 

 judgment. The modesty which was so 

 characteristic shows itself everywhere in 

 the tone of his writings, at the same time 

 that his self-reliance and the earnestness of 

 his convictions led him to express himself 

 with definiteness, and to impress his read- 

 ers with the justness of his conclusions. 

 His writings are widely known and fre- 

 quently quoted abroad as well as in this 

 country. They are wonderfully even ; they 

 are all good; and it is hard to assign to 

 any one of them a special preeminence. 



In 1886, he visited the Mono Valley re- 

 gion of California, and made a preliminary 

 examination of its geology for the United 

 States Geological Survey. In his library 

 there is a reprint of his report of this ex- 

 pedition — 'Quaternary History of the 

 Mono Valley, California' — and on the re- 

 print there is the word 'incomplete' in his 

 handwriting. The Mono Valley region is 

 a charming mountainous country, to the 

 south of the Yellowstone Park, resembling 

 Switzerland except for the lack of snow 

 on the mountains. The country is now 

 being rapidly opened up, and the enthusi- 

 astic alpine climbers there are anxious that 

 it should be explored and made known to 

 tourists. The first report of Professor 

 Russell was so excellent that he was to have 

 been sent by the survey thi^ summer to 

 complete the work which he began so well 

 twenty years ago. 



The best evidence of the success of a 

 scientific man is to be found in the esteem 

 shown him by men of his own branch of 

 science. This Professor Russell possessed 

 to a high degree, and evidence of their 

 recognition of his ability is to be found in 

 the honors which they paid him. 



He was a fellow of the Geological So- 

 ciety of America, and was elected its presi- 



dent for 1906; a fellow of the American 

 Association for the Advancement of Sci- 

 ence, and vice-president in 1904; a fellow 

 of the National Geographical Society, and 

 a member of its board of directors (twice 

 this society sent him on important expedi- 

 tions) ; a member of the Michigan Academy 

 of Science, and its president in 1902; a 

 member of the Congres Geologique Inter- 

 nationale; and of the American Alpine 

 Club, of which he was one of the directors. 

 He was honorary member of the Appalach- 

 ian Mountain Club, and corresponding 

 member of the Geographical Society of 

 Philadelphia, and of the Scottish Geo- 

 graphical Society. He was chairman of 

 the section of geography and a speaker in 

 the section of physiography at the Con- 

 gress of Arts and Science, held in St. Louis 

 in 1904. He received the degree of doctor 

 of laws from the University of New York, 

 his alma mater, in 1897. He was generally 

 recognized as among the foremost of the 

 geologists of the country, and had just re- 

 ceived an advantageous call to a prom- 

 inent university. The University of Mich- 

 igan has been most fortunate to have been 

 able to have had his valuable services for 

 so long, and has met with an irreparable 

 loss. 



He was a scientist of international re- 

 nown, whose writings and explorations 

 were constantly increasing the reputation 

 of this university. He was a scholar of 

 high ideals, whose interest in research work 

 was great, and whose example as a devoted 

 student and tireless worker made itself felt 

 in all our circles. He was a teacher who 

 made his students feel the importance of 

 scientific methods and true knowledge. He 

 was a high-minded, modest, true gentleman, 

 who made himself beloved by all who 

 learned to know him, and most by those 

 who knew him best. His kindly manner, 

 his sense of humor, his playful wit, dry
