Cytological studies have been pursued during the winter 
months as assiduously as time allows. I am anxious to 
complete several phases of cytological studies somewhat 
correlated with problems in heredity. 
Students and Investigators 
During the past year, all investigators formally registered 
in the records of the laboratory have been either recipients 
of Garden scholarships or candidates for advanced degrees 
at Columbia University. Several of the latter, however, 
have been tuition students of the Garden, doing a large part 
of their work under direction of members of the Garden 
staff. A number were primarily Columbia University 
students. The hearty cooperation of Professor R. A. 
Harper, Professor of Botany at Columbia University, has 
been of value in the consideration of various problems of 
student research. Professor William J. Gies has visited the 
Garden for consultation with students whose problems 
involve chemical investigations. 
The degree of A.M. was granted by Columbia University 
during the year to Miss Katherine Reid and Miss Friedolina 
Jud, whose essays were based on investigations conducted at 
the Garden. 
Student use of the facilities of the experimental garden 
and greenhouse has increased, especially as the particular 
problems progress. For these studies, considerable numbers 
of plants have been grown of Hordeum, Tricitum, Secale, 
Althea rosea, Abutilon, Lupinus, Phlox, and Nicotiana. 
In the following list the more complete biographical data 
are given for new students only. In each case the problem 
here stated is the one under consideration at the Garden.
