I understand that, in order to lessen difficulties arising from 
the “ green ” powder settling down in the water, it is the 
intention of Messrs. Blundell, Spence & Co., in the coming 
season, to grind the pulp or paste (that is, the Paris-green powder 
damped with water) to a much finer condition, so that the 
particles of powder being in this finer state will he much less 
liable to sink to the bottom of the fluid. This will be a great 
improvement, and the issue of this paste in glass jars 
will prevent difficulties regarding corrosion of metal caused by 
chemical action of the Paris-green. 
This is a point that should be borne in mind in the use of 
iron or galvanised iron pumps or apparatus. These should 
be carefully washed out before being put away, or the bottoms 
may be corroded away by chemical action. 
The above observations refer solely to the use of Paris- or 
Emerald-green as an application —simply mixed with water for 
destruction of moth caterpillars in the way in which we have 
found by many years’ experience in America, and now by our 
own here, that with proper regard to directions and cautions, 
the work may be carried on with safety and great benefit.

P.S. It would give me pleasure to offer any information in 
my power regarding details of application of Paris-green, or to 
send a copy of this pamphlet to any applicants who may 
desire it for practical service.—E. A. 0.
