The death of chestnuts and oaks due to Armillaria mellca is the 
subject of a professional paper recently published by W. H. Long, 
forest pathologist at Washington, after a special study of this 
disease near New Berlin, New York, and Brim, North Carolina, 
in both of which localities the chestnut canker is at present absent. 
He finds that Armillaria mellca can become an active parasite 
under favorable conditions, especially in chestnuts and oaks, kill- 
ing not only suppressed trees in the forest, but also those that are 
growing under more “favorable conditions; and he believes that 
this fungus has been an important factor in the gradual recession 
of the chestnut in parts of the southeastern United States. 
In Oregon and the adjoining states, where Armillaria mellea 
attacks fruit trees to a considerable extent, Mr. H. P. Barss has 
recommended the removal of all affected dead roots and bark, dis- 
infection with Bordeaux mixture or corrosive sublimate solution, 
and the covering of the wounds with paint or grafting wax.
