nstancy and the time now seems opportune 
to prosecute vigorously the behavior in seed reproduction. 
In various lines of experimental work now in progress and 
especially in the study of seed progenies in Coleus and of 
incompatibility in pe-tsai I am now being greatly helped 
by the voluntary assistance of Mrs. M. J. Fox 
The studies with Cichorium Intybus have paca brought 
to a conclusion and the new results with this species are 
now soon to be published, together with various other 
data on self-compatibility. No further work was done 
during the year with Phlox subulata and with species of 
Hibiscus. I should be pleased to again take up experi- 
mental and field studies of these. 
During the autumn I spent several days at the State 
Experimental Station at Geneva, N. Y., in making observa- 
tions bearing on the fertility of the grape. A report of the 
trip, with recommendations for cooperation with the 
Department of Horticulture at the Geneva Station in 
certain very fundamental studies of the grape, has already 
been submitted to you. Details of the plans for the grow- 
ing of grapes at our Garden for the purpose of general 
public interest as well as for scientific study await your 
further consideration. 
The phenomena of sterility and fertility in the cultivated 
potato have long been of special interest. There are 
undoubtedly two or more types of sterility operating. 
Preliminary experiments have been begun to determine this 
point most conclusively. Various workers in the Bureau 
of Plant Industry and in several State Agricultural Experi- 
ment Stations have greatly assisted me by supplying tubers 
of various fruitless and fruitful varieties and also seeds of 
the latter. IJ am planning to make a comparative and 
intensive study of these during the coming summer on the 
basis of the experience already gained with other plants. 
Several papers dealing with the results of my personal 
research have appeared during the year.
