700 STUART WELLER — 
Professor James D. Dana. He remained in this position for twelve 
years, when he returned to Cornell and continued his work there 
until his retirement as emeritus professor of geology in 1912. 
Professor Williams’ name will always be associated with the 
development of American paleontology and more especially with the 
American Devonian. His more philosophical contributions, how- 
ever, are applicable to the life of all periods. 
As a teacher Professor Williams exercised a great influence in the 
encouragement of his students in research. He did not believe in 
directing each separate step which his pupils took, but he believed 
rather in leading them to search for their own problems and when 
found to solve them independently if possible. He considered the 
field of scientific paleontology to be limited in its possibilities for a 
livelihood, and consequently he never offered undue encourage- 
ment to prospective students to enter the work. To those who were 
bound to enter, however, he gave the best council and advice of 
which he was capable. He was especially a laboratory teacher, and 
he made his students feel that they were companions with him in 
research. He was a man of most amiable disposition and spirit, 
and his kindly smile could never fail to reach one’s heart. He wasa 
loyal friend and always rejoiced in the success of those who had come 
under his instruction.
