Effect on trees.—The grade and the superfine limoid and the 
superfine Marblehead mixtures caused some spotting and burning 
of the leaves and fruit which was accompanied with serious drop- 
ping of the leaves. Some of the trees had the foliage badly 
burned, while others treated by the same preparation showed no 
such injury. The grade Marblehead lime mixture caused more 
serious injury to the foliage and branches than any of the other 
washes. The injuries to the fruit, leaves, and young growth ap- 
peared very’ soon after the treatment. 
Effect on scale.—None of the washes appeared to be constantly 
effective in destroying the scale. While some applications gave 
satisfactory results in this respect, many treated trees were at 
the end of the season as badly infested as the checks. There was 
no practical difference in the effectiveness of the several mix- 
tures. The irregularities seem largely’ attributable to the in- 
stability of the emulsion and its uneven distribution in the wash. 
SUMMARY AND CONCLUSIONS. 
The experiments with the kerosene-lime mixture during the past 
year show that the applications of this wash have given variable 
results upon trees and scale. The lower percentages of oil were 
generally ineffective on scale but the mixtures containing higher 
percentages of oil were more efficient. The comparative test with
