per cent of these sprouts were free from disease, and of the infected 
sprouts, 99, Or 39 per cent, were infected at the base mostly from 
diseased bark left on the stump. 
“The second tract, used for comparison with this, is located about 
one half mile distant from the first tract and was cut about the same 
time. The brush was burned and all the merchantable wood used, but 
the stumps were not peeled. As near as could be determined, the two 
woodlots received identical treatment except that the stumps were peeled 
in one case while they were left with the bark on in the other. On this

The Pennsylvania Commission, after having started these extensive

through failure of the Legislature to appropriate sufficient funds with which 
to continue the work as it had been begun. Much that was valuable 
had been accomplished in scientific research, but the field experiments 
in cutting-out, on which the greater part of the $275,000 was spent, were

In New York State the survey made by one of the writers of this bul-

posed. With the vast area that was then affected, the problem of control
