of students with limited means, and in a quiet way extended aid to many 
of them. He never lost an opportunity for service to his friends or 
others in need; sympathy, helpfulness and loyalty were his characteristic 
qualities as a man and friend; and the loss to all of us who knew and 
loved him is irreparable.’”—J, H. Comstock, Science, December 29, 
1916, p. 913. 
Hundreds of students now scattered to all parts of the country 
have sat at his feet, and can testify to the quiet, unassuming scholarship 
and sympathetic instruction to which they were there exposed. Many 
have attained to eminence in horticulture and forestry through the 
working out of the interest and enthusiasm he engendered. 
As a member of the Academy he was practically always at its 
meetings with an important contribution to make. His presentation 
was always interesting and plain. Continually alert for opportunities 
by which the Academy could serve the Commonwealth and Science, he 
became the channel through which we received our annual, financial aid 
for research from our loyal patron and life member, Mr. Emerson 
McMillin. He served on the trustee committee from 1901 to the time 
of his death and wisely discharged his duties. 
If any difficult problem arose in the affairs of the Academy he was not 
lacking in efficient counsel nor was it hastily or injudiciously given. 
Thus we shall miss his thoughtfulness and wisdom.
