Secondly, his remarkable industry emphasized the effect of 

 his sincere devotion to science. He was not one to tell you how 

 much midnight oil he burned or in any way indicate the inten- 

 sity of his labors, but both their quality and quantity compelled 

 our attention and w-e watched and found that he rarely spent an 

 idle minute. Not only were his working hours long, but in- 

 tensely active. Many of us remember the long, quick stride 

 which carried him so rapidly from task to task ; it was an index 

 of the energy of the mental machine within. 



A letter recently received from a former student wdio was 

 for a time a member of his household says : '"The tireless en- 

 ergy of the man was inspiring. His light was the last to go 

 out in the home, and on going to breakfast early in the morning 

 it was nO' unusual thing to meet Professor Herrick returning 

 from the woods or swamp with a supply of material for the day's 

 classes If he ever took a rest we never knew of it."' 



Some who loved him feared the results of this excessive 

 activity and counseled moderation. But he seemed to be driven 

 to work by some necessity of his very being which would not 

 let him rest. Fortunately the long tramps and vigorous out- 

 door exercise, which his scientific labors demanded, gave some 

 relief from the exhausting effects of the mental application to 

 which he was so inclined, and enabled him to keep up year after 

 year such labors as otherwise would have worn him out. Even 

 those who disapproved of this overwork were forced to admire 

 the unselfish zeal which caused it and felt a new impulse in their 

 own pursuit of truth. 



A third reason for Professor Herrick's ability to instill the 

 spirit of research was found in his subordination of most of the 

 common aims which move men to what was evidently the great 

 aim of his life. Most of us attempt so many things that we do 

 none of them very well. We divide our energies between 

 money-getting, reputation-winning, recreation, self-culture and 

 various public interests to such an extent that nothing- in our 

 individuality stands out to compel the interest of our fellows. 

 But Professor Herrick, while remarkably faithful to all his duties
