do both better by having them separate, and he could cultivate
in his orchard beans and various crops that could be got rid of
when he wanted to, instead of holding them in the ground longer

SPRAYING THE FARM ORCHARD.
PROF. J. G. MILWARD.
To facilitate a prompt discussion of essential details, the writer
has in mind a mixed orchard of about 300 bearing trees. It is
not intended to make any comparison between commercial and
farm orchard spraying, as obviously, the work in the farm or-
chard is merely an application of methods which have been
found profitable on a commercial basis. From the size of the
orchard selected, the small fruit grower should be able to make
the necessary applications to his own conditions.
What will be the cost per acre of spraying 300 bearing trees?
An itemized statement prepared this season from spraying six
acres of apples is given.
Bordeaux mixture formula:
Blue vitrol .........................                8 lbs.
Lime .........................                      lo lbs.
Water ......................... 100 gals.
The cost of 100 gallons of Bordeaux mixture equals approxi-
mately sixty cents.   As indicated in the statement eight
pounds of Arsenate of Lead is added which brings the total
cost of 100 gallons of spray mixture up to $1.50. The necessity
of giving attention to the dates mentioned is important, inas-
much as they cover the season when the common orchard pests
are at work on the trees. The statement given makes full al-
lowance for labor and expense, and if the fruit grower is not
willing to make the investment indicated (relative of course,
to his own conditions) he had better not attempt orchard
spraying.
