His college life began at Hobart, where two years left a deep impression from an acquaintance with Berkeley's thought, gained in browsing in the library, and long treasured up to produce fruit in philosophic views of maturer years. Then at Williams College, where the notable Natural History Society was sending out its expedition across South America, his love of Nature matured and specialized for two years longer, until he received the A. B. degree in 1870. It was Williams also that later, in 1893, bestowed upon him the LL. D. degree. For him the completion of college life was truly the "commencement" and not the finish of his intellectual training. His strong trend toward pure science and abstract mental life forced him onward into post-graduate work. But this required funds, and America was not Germany; the struggle for existence was not here so intense that one might not win bread in many walks of life without special training, and parents did not need to extend the larval period of support for offspring beyond the completion of college life to gain for them a place in any rank, social or intellectual. Now, a rapidly increasing need for the Ph. D. degree as entrance to professional life, necessitating several years of post-graduate study, often forces parents to take up their share in the increased burden. Then, however, few were agreed as to the advisability of prolonging an unpractical life devoted to study beyond what seemed the maximum limit of unproductive preparation for life--the day of graduation at college. Beyond that the young man must make his own way as best he might. The subject of this sketch chose to work his way by his own unaided efforts into the fullest measure of academic training. That was before the day of competition between universities, and there was no temptation to go here rather than there in order to live a semi-parasitic existence as scholar or fellowship holder.
