GRADUATE STUDENTS AND INDEPENDENT INVESTIGATORS 
ENROLLED DURING 1937 
Dr. Harry G. Albaum, Department of Biology, Brooklyn 
College, utilized the laboratory facilities for his studies on the 
influence of hormones on the outgrowth of adventitious sprouts 
from fern prothallia, and on the outgrowth of leaves from young 
fern plants. The results of his investigation formed the basis 
for a thesis for the degree of Doctor of Philosophy at Columbia 
University. 
Mr. Paul F. Brandwein, a graduate student of New York 
University, has continued some of his studies on the loose and 
covered smuts of oats. His data on the latent infection of re- 
sistant oat varieties inoculated with loose and covered smuts have 
been published. 
Dr. Elva Lawton, Biology Department, Hunter College, has 
continued her studies on regeneration and polyploidy in ferns.

Chestnut Breeding Work in 1937 
Our original project was the combination, in a new chestnut 
stock, of the blight resistance of the oriental chestnuts with the 
tall-timber quality of the American chestnut. Now, with in- 
creased facilities for hybridization, the scope of our activities 
has been enlarged to include qualities of nuts, age and season of 
flowering, resistance to cold, drought, and insect attacks, and 
other desirable traits. 
Outside A ssistance.—It is a pleasure to mention the encouraging 
words and offers of material assistance from many friends. In 
December, 1936, we received through the Hon. Gifford Pinchot 
of Pennsylvania and Dean Henry S. Graves of the Yale School of 
Forestry at New Haven, a contribution of funds from Mr. 
Godfrey L. Cabot of Boston. In addition, for the second year in 
succession, we received through the National Research Council, 
Washington, D. C., a grant-in-aid from the National Academy 
of Sciences; and during the summer the Division of Forest 
Pathology, U.S. D. A., helped us financially.
