times its weight of lime, or with the Bordeaux mixture. The composi- 

 tion of lyondon purple is exceedingly variable, and unless good reasons 

 exist for supposing that it contains as much arsenic as Paris green, use 

 the latter poison. Do not use the lyondon purple on peach or plum trees 

 unless considerable lime is added. For insects which chew. 



Copper Sulphate Solution. This is specially useful for fungus 

 diseases. 



1 pound Copper Sulphate. 

 15 gallons Water. 



Dissolve the copper sulphate in the water, when it is ready for use. 

 This should never be applied to foliage, hvr must be used be- 

 fore THE BUDS BREAK. For peaches and nectarines use twenty-five 

 . gallons of water. 



Paris Green. This is principally used for insects which chew. 



1 pound Paris Green, 

 200-300 gallons "Water. 



If this mixture is to be used upon peach trees, one pound of quick-lime 

 should be added. Paris green and Bordeaux mixture can be ap- 

 plied WITH PERFECT safety. The action of neither is weakened, and 

 the Paris green loses all caustic properties. 



White Hellebore. This poison is not so energetic as the arsenites 

 and may be used a short time before the sprayed portions mature. For 

 insects which chew. 



1 ounce Fresh White Hellebore. 

 3 gallons Water. 



Apply when thoroughly mixed. 



Kerosene Bmulsion. Kerosene and water are very hard to mix. 

 This mixture should be churned frequently while using. 

 I pound Hard Soap, 



1 gallon Boiling Water, 



2 gallons Kerosene. 



Dissolve the soap in the water, add the kerosene, and churn with a 

 pump for five or ten minutes. Dilute ten to twenty-five times before ap- 

 plying. Use strong emulsion for all scale insects. For insects which 

 suck, as plant lice, measly bugs, red spider, thrips, bark-lice, or scale. 

 Cabbage worms, currant worms and all insects which have soft bodies, 

 can also be successfully treated. 



Cucumber Beetle. This beetle may usually be prevented by 

 dusting the plants with plaster of Paris and Paris-green.
