versity of Manitoba, Winnipeg, Canada, and Director Cas- 
siano Conzatti of the Botanical Gardens of the State of 
Oaxaca, Mexico. But of all of these only Professor Wille 
was able to be present.

delegates would be prevented from taking part in the exer- 
cises, an invitation to participate in the celebration and 
present papers at the scientific meetings was extended to 
Director Johanna Westerdijk. of the Phytopathological 
Laboratory, Amsterdam, Holland, and Geheimer Regie- 
rungsrat Dr. O. Appel of the Kaiserlichen Biologischen 
Anstalt fiir Land- und Forstwirtschaft, Berlin, Germany, 
both of whom happened to be in this country at the time of 
the celebration. Both accepted and were present to read 
papers. 
All of the botanists of the United States who had accepted 
the invitation of the Board of Trustees to read papers at the 
scientific meetings of the anniversary celebration were 
present. These included the following: Professor George F. 
Atkinson of Cornell University, Ithaca, New York; Profes- 
sor Charles E. Bessey of the University of Nebraska, Lincoln, 
Nebraska; Dr. N. L. Britton, Director in Chief of the New 
York Botanical Garden, Bronx Park, New York City; Pro- 
fessor John M. Coulter of the University of Chicago, Chicago, 
Illinois; Dr. D. T. MacDougal, Director of the Department

ington, Tucson, Arizona; Professor William A. Setchell of 
the University of California, Berkeley, California, and Dr.

partment of Agriculture, Washington, D. C. In addition 
invitations to be present at the anniversary exercises were 
extended to all American botanists and to a limited number 
of other scientists. 
Dr. W. G. Farlow of Harvard University, Cambridge 
Massachusetts, in response to an invitation from the Board 
of Trustees, spoke in behalf of the American botanists at 
the Trustees’ banquet, which marked the close of the anni- 
versary exercises.
