large tuft of needles at the end are convenient instruments for 
jarring or brushing the bushes. To make this work more effectual 
the soil between the rows should be kept. well cultivated and free 
from weeds. ‘The work should be done during the heat of the 
day when the soil is dry and crumbles easily. It should be the 
aim of the operator to brush the larve so that they will fall be- 
tween the rows as far from the bushes as possible, the object 
being to make them fall on the loose earth where many of them 
will die from exhaustion in an attempt to return to the vines. 
Mr. Mikelson, who has tried this method, says that he met with 
good success. His soil is a light, sandy loam. ‘Where children 
or other cheap help can be employed, this method is probably 
cheaper than spraying. If-only a few bushes are infested it is a 
quick and easy method of checking the pest. 
Fall cultivating.— The object is to bring the cocoons to the sur- 
face of the ground where they will be exposed to the weather. | 
As a fair percentage of the cocoons are found from a foot to two 
feet from the bushes, some good could probably be done in this 
way, but the method needs further testing. 
Spraying.— Two kinds of insecticides may be used in a spray 
against this insect, namely, arsenical compounds and _ hellebore. 
Both are efficacious, but hellebore is usually preferred, because of 
the prejudice against the use of arsenicals on rapidly developing 
small fruits and because hellebore does not disfigure either fruit 
or leaves. $y 
Eaperiments.— A large field of raspberries belonging to Mr. 
Mikelson, which was badly infested with this insect, was divided 
into three plats for the purpose of the experiments. Plat I was _ 
sprayed June 4 with arsenite of lime, 1 pt. of the stock solution to 
40 gallons of lime water; Plat IL with hellebore, 1 oz. to 1 gallon 
of water; Plat III was left unsprayed. 
FResults.— On the second day after this application practically 
all the larvee were dead on the sprayed plats. On Plat I the 
leaves were seriously injured, but as subsequent experiments with
