plants at these institutions afforded much that was interesting 
and instructive. 
y was spent at the experimental eoedene of Professor 
Baur at Friedrichshagen. Here we met Professor Baur and 
several of his assistants and students, all of whom very kindly 
explained the various experiments under way which were chiefly 
concerned with hybridization studies of various cereals, of cab- 
bage, kohlrabi, cauliflower, kale and brussels panes and of 
turnips and rape. It was a particular Lene that we were ac- 
companied on this trip by Dr. George H. Shull of the eee for

Dr. Shull has been spending a year in Berlin and was well posted 
on the work at Friedrichshagen. We also dined and spent a 
pleasant evening with Dr. and Mrs. Shull. The 26th, which 
was Sunday, was spent in a long walk ia the Tiergarten,

Early the next morning we started fot es which we
