344 REpPoRT OF THE DEPARTMENT OF ENTOMOLOGY OF THE 
various limes showed that the best results were obtained by the 
use of limoid. 
The percentages of kerosene in well prepared mixtures were 
determined by Mr. Baker, as given in detail in the next section. 
These determinations indicated that the larger percentage of oil 
is formed into an emulsion with a portion of the lime which re- 
mains in suspension, while the remainder of the oil, which is small 
in quantity, is carried to the bottom by the lime which settles. 
Probably the chief reason for the variable results upon scale 
attending the application is the imperfect distribution of the 
emulsified lime-oil portion in the mixture. 
While the use of the kerosene-lime wash in this work has on 
the whole proven unsatisfactory, it is intended to continue the 
experiments next season to determine if a safe and efficient com- 
bination of the oil and lime can be made.
