Feb., 1912. Mammals of Illinois and Wisconsin — Cory. 271 



trunks of fruit trees from the depredations of these animals as well as 

 from mice: 



Unslacked lime 20 pounds, 



Flowers of sulphur 15 pounds, 



Water to make 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 Jose 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."
