Green arsenite is a simple arsenite of copper similar in texture 
and chemical composition to Scheele’s green. It is as poisonous 
as Paris green, is cheaper to manufacture, and is an impalpable 
powder instead of -crystalline, hence it will remain suspended in 
water longer than ordinary Paris green thus insuring a more even 
application to the foliage. Tt should be used with lime in the 
same manner as Paris green.

Works have placed upon the market an arsenical which may be

green in the Station orchard during the past two seasons with 
excellent results. |
