204 BOTANICAL GAZETTE. { November, 
and nudges among themselves, watch the professor banter 
with Hans. Then, when the masquerade is revealed, ‘* Don- 
nerwetter’’ changes to ‘‘ Entschuldigen Sie,” and all is well, 
although it sometimes happens that nothing but the payment 
of the regular three marks’ fine will secure the peaceful and 
undisputed progress of the expedition. An unfailing feature 
is the halt for lunch at some convenient ‘ Gasthaus,’’ where, 
over black bread and sausage and mugs of foaming beer, 
many an interesting botanical question as well as jolly joke 
or story is discussed. If a part of the excursion is by rail, 
tickets are taken third class, and even these are obtained, 
in such cases, at reduced rates. x 
At play or at work I have found the German professors 
and students wholly interested and in earnest. Perhaps thus 
their work obtains a character of reliability and thorough- 
ness ; perhaps thus they are able to derive such satisfaction 
from the most minute and tedious investigations and inspire 
in new students such enthusiasm and devotion. Certainly, 
working or playing, I was glad to count my connection with 
the botanical people at Gottingen among the pleasantest of 
my university experiences.
