the tree to about eight feet from the tree, where in- 
fection ended. The point of original infection was not 
discernible but it was probably midway in the part 
examined, since decay was most advanced there. Sur- 
face indications of the fungus are occasional rhizo- 
morphs, delicate rusty tufts of mycelium two to four 
millimeters long, and some blackish material in cracks, 
suggesting a slight oozing at the time of invasion of the 
bark. ^ When cut into, the large, creamy plaques of 
mycelium show in and under the bark and the wood 
shows a white decay progressing from the surface in- 
ward. The fungus evidently progresses along the root 
readily, though rather slowly, but crossing from one 
root to another in the oak is difficult. 
This situation suggests that it may be feasible to un- 
cover all the roots of large trees and remove all the 
infected roots so that the fungus would be prevented 
from reaching the crown and girdling the tree as has 
occurred with several oaks on the campus of the Uni- 
versity. The results secured from the thorough treat- 
ment of the campus oaks will be watched with much 
interest. — W. T. Horne.
