Tree Root-Rot. 



trampling under foot simply disperses the spores and does 

 more harm than gx>od. 



If a tree is suspected of being diseased, this can soon be 

 ascertained to a certainty by exposing the base of the trunk 

 and a root ; the presence or absence of white mycelium under 

 the cortex will decide the question. If other trees grow in 

 the vicinity of a diseased tree, the latter should be isolated 

 by mean s of a narrow trench about 9 inches deep, made at a 

 distance of 3 or 4 yards from the trunk of the diseased tree,, 

 for the purpose of intercepting the progress of underground 

 rhizomorphs. The soil removed in digging should be thrown 

 inside the trench. 



An illustration of the fungus is given in the Kew Bullctin y 

 Nos. 147 and 148, price 8d., published by Messrs. Eyre and 

 Spottiswoode, East Harding Street, E.G.
