Reports of Consulting Entomologist. 409 
It will be observed that the term Paris green ' paste ' is used. 
In order to avoid risk to health from careless workers inhaling the 
powder, one of our chief supply firms arranged to send out small 
orders damped, which saves all danger from inhalation in mixing. 
Besides the above experiments, which are considered to be pro- 
gressing satisfactorily, I have had information of the successful 
use of the Paris green, or arsenite of copper, from private correspon- 
dents, and am in much communication on the subject, and also (it 
being a new application here and a poison) I invariably warn that 
it is not to be left about nor the powder inhaled. At present the 
main point under consideration is, I believe, date of application. 
Mr. Masters added to the observations on the part of the com- 
mittee that they considered the syringing should be done when the 
leaf bud was first developed, before the blossoming period, and then 
again after the blossoms had disappeared and the fruit was forming. 
The work is considered to have progressed satisfactorily, and 
if, as there appears to me reason to hope, our operations succeed as 
well as they have long done in America, the hard and skilled work 
of the Evesham Committee will be a benefit throughout the country. 
Mr. C. D. Wise, the Deputy-Superintendent at the Fruit 
Grounds at Toddington, writing on May 28, says : — 
We have, as you know, tried all sorts of mixtures, and I don't think it 
is worth while troubling you with all particulars of them, as they were all 
useless or nearly so. Paris green is the only thing which we have fouud 
really efficacious. For plums the proportion is 1 oz. to 10 gallons, and for 
apples 1 oz. to 20 gallons. We have also used the former strength for 
currants, but as the foliage is within the last few days becoming so much 
stronger, we have been using it at 1 oz. to 8 gallons. Neither of these solu- 
tions has damaged the foliage, but killed the caterpillar. 
The Paris green should certainly not be used any stronger than we have 
used it. 
As regards the Riley nozzle, we have tried it and found it very similar 
to that on the French pumps ; in fact, there is very little difference between 
the two, that is, in the way the liquid is distributed. 
Owing to an attack of green fly on the plums we have lately been 
syringing thein with 2 oz. of quassia and 2 oz. of soft soap to 1 gallon of 
water, with Paris green added in the proportion before named. The Paris 
green should certainly not be used any stronger than we have used it. 
Mr. Masters, the secretary of the Evesham Experimental Com- 
mittee, has reported, continuing his previous information as to the 
efficacy of the Paris green in destroying the caterpillar, and also 
confirmatory proof that the Paris green might be used with perfect 
safety to foliage at a greater sti-ength than that mentioned above. 
He also noted that in some districts where the greasing precautions 
were resorted to, and where there was no fruit to encourage the 
grower to take any precautions, the trees were looking desolate — as 
bad as if fire had been scorching the trees. 
I also requested information from Messrs. A. Salmon (Fruit 
Growers), near Hounslow, in order to obtain a report of the effects 
of the application on a regular scale of working business, with ordi- 
nary garden engines, and Messrs. Salmon reported in reply, on the
