erature; the energy, liopefulness, enthusiasm which he carried 
into his work and imparted to his associates; his genuine in- 
dividual interest in his students; the friendliness and help- 
fulness of his relations to his colleagues and his readiness to 
cociperate in every worthy undertaking." 
lie who trains students insures his own immortality. The 
young geologists, quick with the inspiration caught from in- 
tercourse with this nian, will be his best and perpetual memo- 
rial. They are not many, his career was too short; but 
through them his elevating ideas and clear purposes for his 
science will not be lost. 
There is one phase of this career, the best of it, he himself 
would have said, that in which la}^ the poetry of his life, which 
must not be overlooked. This was his total and unreserved 
devotion to his home. It is the more fitting to mention this 
here as many of the readers of these pages have shared the 
hospitality and known the loveliness of that home. It was a 
spot where every geological worker was welcomed, whose en- 
tire resources were at the command of the scientific comer; 
and, to the students, the point where they came into closest 
touch with the personality of the teacher. 
In 1886, Mr. AVilliams married Mary Wood, a daughter of 
the late Hon. Daniel P. Wood, of Syracuse, N. Y., a man 
widely known for his accomplishments in law and statecraft, 
and whose appreciation of science was evinced, during his 
long career in the legislature of his state, by the generous and 
unflinching support which he accorded to the work of its geo- 
logical survey under professor James Hall. The marriage 
brought about one of those rare relationships in which the 
work of the man found at once its most appreciative co<)per- 
ation and support, and its most rigorous critic, in the intel- 
lectual intuitions of the woman. The value of such compan- 
ionship, not alone to the worker, but to his work, is not often 
overestimated. In his peripatetic work she was often his 
companion, accompanying him among the hills of Maryland 
and upon his Norwegian trip with Prof. Kosenbusch and Dr. 
Reusch ; and in the study she was his first and acutest auditor. 
Three sons were born into this home, two of whom still live, 
one of them bearing his father's name.
