The remaining technical section of 

 the branch of products is that of 



PATHOLOGY 



This section investigates the diseases 

 which cause the decay of wood. Its 

 work is closely allied with that of wood 

 preservation, and the problems will be 

 of the same kind, although the work 

 of the two sections will be entirely dis- 

 tinct. The work in forest pathology is 

 conducted in the bureau of plant indus- 

 try of the Department of Agriculture in 

 Washington, and that bureau provide^ 

 the working staff and has charge of the 

 technical methods.
