Till'] CllAIK.MAX: Aiv lli»'re any (inestions for Professor 

 Clinton? 



MR. CriESTEK E. rillLl): I wouj.l like to ask Professor 

 Clinton what was the result of the cutting out of the infected 

 trees on any tracts or estates he knows about; where the affected 

 trees were removed, what was the result on the trees thai re 

 mained? 



rKUrJ':SS()R CLIXTOM: That was on the estate of one of 

 the wealthiest men in Connecticut, so he had money enough to 

 cut them out if he wanted to. It was on the southern exposure of 

 a hill and we found that, where cut out, the trees left seemed 

 to suffer more from drought, etc., and be more injured by blight. 

 We also found that by cutting out the trees and not removing 

 the bark from the stumps, about thirty per cent, of those stumps 

 showed the disease present on the bark that was left. Up to 

 last summer the forests in the same region, on the northern ex- 

 posure, had not suffered much from blight. This gentleman 

 said that he would go on if we wanted to continue the experi- 

 ment, but he thought, as far as he was concerned, in the future 

 he would prefer to cut the trees as they died. That was not 

 a thorough, careful experiment like they are going to conduct 

 here in Pennsylvania, by cutting every diseased tree down and 

 burning the bark and all that, but it was about the way a prac- 

 tical man would do it.
