London Purple is prepared in the same way as the above, the lime 

 being again essential. 



" Arsenate of Lead is prepared as follows : — Dissolve 1 oz. of arsenate 

 •of soda in warm water, and add to 16 gallons of soft water. Then dissolve 

 ■3 oz. of acetate of lead in water, and pour into the 16 gallons of liquid. 

 Add to this 2 lb. of treacle. In the place of treacle the arsenate of lead 

 wash may be mixed witli paraffin emulsion, and so a double insecticide 

 prepared. This wash when properly mixed is most successful, and never 

 burns the leafage, as growers often find to be the case with Paris green. 



" In all cases proper sprayers must be used with fine nozzles, so that 

 .a dense mist of the wash may be thrown on the trees." — R. N.
