REPORT OF THE DIRECTOR OF THE LABORATORIES 
ON HIS TRIP TO EUROPE 
Dr. N. L. Britton, Drrector-In-CHIEF, 
Sir: In accordance with your instructions, I spent the tim 
from July 11 to August 22 in a trip to Germany, Holland aa 
England, for the purpose of visiting botanical gardens, institu- 
tions for botanical research and concerns engaged in the com- 
mercial production of seed. Special study was made of the 
methods used in plant breeding and of the equipment of labora- 
ories. It was also planned to collect specific data which are 
relavent to the experimental work that I am conducting at our 
Garden with Coleus and Cichorium Intybus.
