trunks of fruit trees from the depredations of these animals as well as 
from mice: 
Unslacked lime..... oe bth ...20 pounds, 
Flowers of sulphur....... ee ..15 pounds, 
Water tomake..... ..... 0 «1... .45 to 50 gallons. 
This will make a quantity about sufficient to fill an ordinary kerosene 
barrel. Lantz says, ‘‘A little salt may be added to increase the ad- 
hesive property of the mixture. The lime, sulphur, and about a third 
of the water are boiled together for at least one hour, and the full 
quantity of the water is then added. For San José scale the wash in 
the form of a spray is applied to the entire surface of the trees. For 
protection from mice and rabbits the trunks only require treatment, 
and the wash may be applied with a brush. One application in Novem- 
ber should last the entire winter.”
