Directions for spraying.—The following suggestions are substantially 
as given to our correspondents during past seasons. To obtain the 
best results it is necessary to spray the vines a day or two before 
blooming, and again two or three days after first bloom, at least three 
applications being made at intervals, the different applications being 
graded with a view to keeping the buds and blossoms constantly cov- 
ered with a thin coating of whatever substance is used. Thus, if the 
variety of berry to be treated begins to bloom April 27, it might be 
sprayed on the 24th or 25th, again on the 29th or 30th, and a third 
time, say May 5. Itis doubtful if a fourth spraying would be profitable, 
unless more frequent applications be made, except in the event of rain 
or heavy dew fall after spraying, as the chief damage is done usually 
during the first two weeks of blooming. 
The best form of apparatus for spraying garden plants is the knap- 
sack sprayer, fitted with the finest Vermorel spray-nozzle, but for larger 
beds a spray tank mounted on a cart or wagon should be used. 
The periodical or intermittent nature of this insect has always mili- 
tated against its successful treatment. Fruit-growers are too prone to 
“trust to luck”? until it is too late for the application of remedies with 
any degree of promise. It should be borne in mind that whatever 
course of remedial or preventive treatment is pursued it must be begun 
before the insect appears. Two weeks’ uninterrupted work on the part 
of the insect is sufficient, during its years of abundance, to so damage 
a crop as to make it unprofitable for picking.
