Summary of results — The peaches generally proved very much 
more susceptible to injuries by complete or partial immersion in 
the lime-sulphur wash than any of the other kinds of fruits that 
were tested. Injuries to the buds were caused by the dipping of 
the tops in the mixture for periods of three or more minutes, ant 
the tops of the trees were killed by immersion for ten minutes. 
Trees with their roots immersed in the lime-sulphur wash were 
seriously injured or killed by the treatment. Of 188 trees that were 
dipped with the roots 179, or 95 per ct. of the number treated, 
were killed. All of the checks, thirty in number, made a normal 
growth. 
ROOT INJURIES BY IMMERSION IN SPRAYING MIX- 
TURES. 
The trees with roots immersed in the sulphur wash frequently 
sustained injuries. The effects of this treatment upon the health 
of the plants were most plainly apparent about fourteen days after 
the trees were in leaf. The first indications of the injuries were 
by the wilting and curling of a few leaves, which during a succes- 
sion of hot days gradually extended to the entire foliage. The trees 
that were extremely affected soon became defoliated, from which 
they did not revive. The growth that was made appeared to be 
entirely at the expense of the reserve food material which ae been 
stored up in the main axis of the plants. 
An examination of the underground portions of a fifhePSE 
trees dipped in the wash showed that the root system may be seri- 
ously damaged by this treatment. The extent of the injuries was 
not constant and varied with individual plants of the same variety. 
Cross sections of immersed roots, which externally exhibited no 
evidences of injuries, showed frequently a discolored cambitim. 
Large portions of the tips of the older roots and ‘often entire 
smaller roots were killed. In some instances the cambitim was
