DISEASES. 153 
Often a white fungus occurs and permeates the 
entire ear. 
This disease was first investigated in 1852, 
and most of the information known of its char- 
acter is derived from studies made of it by 
Prof. T. J. Burrill of the [linois experiment 
station.* The malady is widely prevalent, with- 
out doubt, yet is mainly known in Illinois and 
Nebraska. It is thought that animals eating 
cornstalks affected by this bacteria will die of 
what is called “cornstalk disease.” 
While this trouble is not confined to special 
kinds of soils and conditions it has been found 
most prevalent on rich land. 
Thus far the writer knows of no method 
proposed to prevent the occurrence of this 
disease. 
Rust occurs on Indian corn, but only to a 
shght extent and at uncertain periods. The 
loss from this disease is probably very imma- 
terial.
