Much of this research with Lilium will be prosecuted by 
Mrs. Fox. I shall advise and cooperate as fully as may be 
desirable. 
The routine duties incident to my position have been 
duly performed. Meteorological data have been taken and 
properly recorded. Programs for the monthly conferences 
of the Staff and registered students have been arranged and 
reports of these have been published in the Journal. I 
have given four public lectures at the Garden during the 
year. 
During the spring months the Garden cooperated with 
Dr. D. T. MacDougal, Director of Botanical Research of 
the Carnegie Institution, in installing a dendrograph to 
a tree of the sugar maple and securing the records. At 
your direction, I took charge of the apparatus and sent all 
records to Dr. MacDougal. 
On July 1st, the position of technical assistant in the 
laboratories, vacant for two years previous, was filled by 
the appointment of Miss Hester M. Rusk, who is now assist- 
ing me in the discharge of various routine duties and in 
prosecution of research. 
Personal Investigations 
As noted in my previous reports, the greater part of my 
personal research is being directed to studies of fertility 
and sterility concerning which I have already published 
several papers. I have now investigated numerous species 
in which the various types of sterility are operating. The 
study and survey of all types of sterility in plants is being 
extended as fully as time and facilities permit. There has 
been some opportunity to apply what is being learned about 
sterility and fertility to crops in which production of fruit 
and the breeding from seed are matters of practical as 
well as scientific interest. My cooperation with the 
Experiment Station at Geneva, N. Y., in the study of the 
grape, for which IJ have your permission, is perhaps a 
logical result of my researches on intersexualism.
