MISSOURI BOTANICAL GARDEN BULLETIN 61 
Goodwin (who is deaf) asked for the formula of hydrocyanis 
acid gas. Wilhelm asked if shade were necessary in growing 
ferns. Stenzinger asked how to sterilize soil. 
Every Thursday is review day and one class the boys look 
forward to. The lecture is of two-fold value: The students 
have to face an audience of practical critics. Every one has 
to study the lecture of the week, and be able to answer his 
own question as well as the question of others. Then, too, 
our lecture afternoon is so full of interest to every one that 
no one falls asleep, as they might if one man lectured.
