A. —Kernel from sample 321, infected with Gibberela saubinetii, in which the para¬ 
site has reached the germ and the cavities about the germ. Whenever the germ is 
invaded by any of the several parasites herein described ^germination is either inhib¬ 
ited or greatly retarded. Eighty per cent of the kernels in this sample would not ger¬ 
minate. X30- 
B. —Kernel from Ear 10 B, infected with Diplodia zeae, in which the parasite has 
reached the germ and the cavities about the germ. (See PI. 9^ A.) Seventy

the surface appeared normal. X30.
