with twelve times its bulk. The mixture should be 

 stirred thoroughly before application. 



(2) Lime and Sulphur Solution 



Fresh quicklime 50 pounds 



Sulphur 100 pounds 



Water 50 to 60 gallons 



The lime is slaked in a little water, and the sulphur is 

 made into a paste. Both are boiled together in sufficient

When ready for use on dormant trees, as for San Jose" 

 scale, the spray should be diluted with eight times its vol- 

 ume of water or more exactly so that the hydrometer (an 

 instrument to measure densities) reading is 1.03. For 

 summer control work, that is, when the spray is to be 

 used on foliage as a fungicide as well as a weak insecti- 

 cide it should be diluted twenty-four times its volume 

 with water, or so that the hydrometer reads 1.01. 



These external poisons coat the insect's body with a 

 fine film, and close up its breathing pores. The spraying 

 must be done thoroughly, so as to reach all insects upon 

 the plant. The principle is the same as that of sprinkling 

 chickens with a chicken powder to kill lice.
