538 PROCEEDINGS OF THE SAINT LOUIS MEETING 



He knew nothing of envy. The world with its rewards was large enough 

 for him and all others besides; but he seemed to feel it a sacred duty 

 to protect those who had gone before, to prevent others from ignoring 

 them, and to secure for them all honor for their work, even though it 

 were imperfect. Ever readj^ to defend the rights of others, he was in- 

 different to his own. If another appropriated his work, he appeared to 

 feel no irritation; rather was he inclined to regard the confiscation as 

 evidence that his work had proved to be a genuine contribution to 

 knowledge. He loved to remember the good and to forget the ill done 

 by others with whom he had been in relation. On one occasion the 

 writer endeavored to dissuade him from a contemplated action, assuring 

 him that the person to be benefited was more than unfriendly. The 

 answer came sharply, " Friend once, friend always ; that is my motto. 

 If you wish to have a happy old age, you will do well to take it for your 

 own." This was no burst of rhetoric ; it was the explanation of his life. 

 Professor Lesley was the last of the old geologists, the only link bind- 

 ing us to the men of the early years, 1837 to 1841. His life was prooj 

 that the tradition respecting the character and ability of those men is 

 true. He was a cheery, winsome companion, an effectionate husband 

 and father, loved and revered in his household, honored by his friends. 

 As was fitting, he passed away without suffering, literally crossing the 

 threshold in sleep. In 1849 he married Susan Inches, daughter of the 

 Honorable Joseph Lyman, of Northampton, Massachusetts, who, with 

 two daughters, survives him.
