investigations in genetics and pathology, a considerable 
number of plants have been grown, especially of Abutilon, 
Phlox, Nicotiana, Hordeum, Triticum, Mercurialis, Mat- 
thiola, Hicoria Pecan, and Zea Mays. Corn was grown for 
genetical study by Professor R. A. Harper. Besides these, 
plants were grown for my own investigations. The 
growing of plants of special interest to students of heredity 
has also been continued. 
Miscellaneous Duties 
The records of rainfall and temperature at the Garden 
have been taken and monthly summaries of the same 
prepared for publication in the Garden Journal. As 
secretary of the conferences of the scientific staff and 
students of the Garden, I have planned programs for the 
various monthly conferences. During the past year, [ have 
also continued as editor of the Garden Journal. 
Personal Investigations 
Progress has been made in the various personal inves- 
tigations mentioned in my report of last year. Plants of 
the second generation of various crosses between types of 
Cichorium Intybus were grown during the year and con- 
siderable data obtained regarding the behavior of self 
sterility and the inheritance of flower color, number of 
flowers, and shape of leaves. 
The studies with Verbascum Blattaria have been some- 
what retarded by the unexpected winter-killing of about 
2,000 plants. New plantings were made in the spring 
and a considerable number of plants forced into bloom as 
annuals. ‘Those remaining over the present winter have 
been mulched in an attempt to prevent winter-killing. 
Two cases of wide variations or mutations in J erbascum 
appeared during the summer. In one case, the plant was 
much branched, with abundant proliferation from the 
ovaries. In the other case, the branches were long, 
slender, and somewhat twining, and the flowers were small
