FORMULAS. 



PARIS GREEN. 



Parts. Per bbl. 



Paris green, 1 lb. ^ lb. 



Quick lime, 1 lb. :^ lb. 



Water, 200 gals. 50 gals. 



This is too strong for the peach, where 2^ oz. each of Paris green 

 and quick lime should be used instead of | lb. Keep the mixture 

 well stirred while using. To make it, mix the Paris green and the 

 lime and add enough of the water to slake the lime, stirring while 

 hot, then add the rest of the water. 



Good Paris green gives far better results ihan the cheaper grades. 



ARSENATE OF LEAD. 



This is a comparatively new insecticide, its value having only be- 

 come known within a few years. It has several advantages over 

 either Paris green or I.ondon purple, tly^ chief ones being that it re- 

 mains more easily suspended in water, thus requiring much less stir- 

 ring up during the spraying; that it shows plainly on the leaves, in 

 dicating w^here the spray has reached, and where it has not; and that 

 large proportions may be used without danger of burning the leaves. 

 It is therefore especially useful where the leaves are particularly sen- 

 sitive.
