of the identity and relationships of the various forms and species. Nor can
we measure the results merely by reviewing his own publications but must
take into consideration how he reached out into the lives of his students, his
assistants, his correspondents, and his colleagues, spurring them on to an
ever widening circle of activities. Some of his associates, who in their own
turn have been active, have already been named as collaborators in the book
on The Plant Rusts. We would fail if we did not name Bolley, Olive,
Whetzel, Johnson (A. G.), Christman, Dodge, Garrett, Bethel, Holway,
Rosen, Stevens (F. L.), Clinton, Kunkel, Thurston, and Cummins, who were
influenced either directly or indirectly. There are many others whose contributions were less extensive but nevertheless important. It is not given to
many men to be so productive both through their own efforts and through
their influence on the efforts of others.
Dr. Arthur was a member of Sigma Xi; the American Society of Naturalists ; the American Philosophical Society; the Academy of Natural Sciences of Philadelphia; the American Academy of Arts and Sciences; the
Indiana Academy of Science (president, '93) ; the American Association
for the Advancement of Science (vice president, '95) ; the Society for the
Promotion of Agricultural Science; the Botanical Society of America (twice
president, '02, '19) ; the Torrey Botanical Club; the American Phytopatho-
logical Society (president, '33); the Mycological Society of America; the
Deutsche Botanische Gesellschaft; and the Russian Botanical Society.
The life and work of Dr. Arthur should serve as a great inspiration to
ambitious young workers. A pioneer spirit, real resistance to discouragement, industrious habits, sound scholarship, unflagging persistence, and
singleness of purpose led Dr. Arthur to high achievement.
