with a brush, rubbing in well ; drench top and leaves with 

 a rose syringe. Apply twice a year, spring and fall; 

 oftener if the grove is seriously infested. 



No. 2. 



Tobacco stems, 5 pounds, 



Copperas, 5 " 



Water, 40 gallons. 



Boil tobacco in sufficient water to extract the full 

 strength ; strain and measure liquid ; put in a barrel and 

 add enough water to make up the forty gallons; then add 

 the copperas and stir till dissolved. Apply as before 



stated. 



No. 3. 



Whale-oil soap, 10 pounds, 



Kerosene oil, 5 gallons, 



Water, 5 " 



Common soap will do if the other is not to be had. 

 Dissolve the whale-oil soap in hot water, then add the 

 kerosene; churn them together until well mixed. For 

 use: add one quart of the emulsion to two gallons of 

 water. Apply as before. 



This preparation is destined to supersede the lately dis- 

 covered "kerosene butter," made by combining the con- 

 densed milk and kerosene, as being much cheaper, quite 

 as effectual, and much less labor to prepare. It does not 

 injure the most tender shoots, and kills the scale at once ; 

 is also a valuable fertilizer, and as it falls back from the 

 leaves and sinks into the ground, drives away other insects 

 that may be hiding around the tree. 



No. 4. 



Cotton -seed hull meal or ash; syringe the tree with 

 water, then throw up the ash into the tree.
