PLATE 4 
A. —The same jars as those illustrated in Plate 2, F. The com plants were 27 days 
old. Diplodia zeae appeared to cause a marked inhibition of growth. 
B. —The same jars as those illustrated in Plate 3, C. The com plants were 27 days 
old. The fungus referred by Manns and Adams to the species Cephalosporium sacchari 
Butler has caused no noticeable ill effects except in one plant which appeared to be 
somewhat weakened in growth. 
C. —The same jars as those illustrated in Plate 3, D, showing the work of Cephalo¬ 
sporium sacchari Butler, cultures of the fungus direct from India. The com plants 
were 27 days old. The plants in one jar have died. The plants in the inoculated 
jar at the right have almost recovered from the setback received in the seedling stage. 
D. —This photograph was taken when the com plants, were about 62 days old. 
They were growing well and had a good color. This shows that with proper handling 
com plants may be grown to a considerable size in jars as small as a Mason quart jar. 
The plants on the right were inoculated with the fungus referred to tentatively as 
Cephalosporium sacchari. The plants in the jar at the lefl were controls and received 
no inoculation.
