SERENO WATSON. 411 



But as we all know, this unsought reward of posthumous fame is 

 his. That it should have come to one who did not fall upon his life 

 work until middle age shows how well that life work was done after 

 it was well iu hand. One of his friends has fitly said: " Had he died 

 twenty years after graduation, the world would have known little of 

 him, and his classmates would have considered his life a failure. 

 That long period, however, comprised years of diversified preparation, 

 which enabled him to bring to his chosen task thoroughly trained 

 powers and gave him a range of knowledge drawn from the study 

 of several sciences." 



A loyal son of Yale College, he was also devoted to the College of 

 his adoption. Almost his last request was that his remains might be 

 placed in the Harvard University grounds at Mount Auburn. There 

 they rest, near by the tomb of his associate and constant friend, Asa 

 Gray.
