WHAT SPRAYING SPRAYING

Spraying machinery is intended to
deliver the spray mixture in such
way rs TO cover the trees thoroughly
In the shortest possible time. This Is
accomplished by placing the liquid
under pressure and delivering II
through small aperture, whereby II
~ broken up into tine mist which
can be driven upon all parts OF the
tree, says the journal OF Agriculture.
The first consideration, then, is the
power, and the second the pump, the
hose. extension rods and nozzles
The power IL usually derived from
man work. gasoline engine or com
pressed air. The first is the cheapest
and most practical when less than
500 trees are concerned, but when 500
to 1000 trees must be treated gaso.
line engine Is needed, and when more
than 1000 trees are 10 be sprayed
compressed air might be prohtably
employed.
lit Is quite possible that some grow
ers owing to scarcity OF labor will
find the gas engine most practical for
smaller number Of trees than 800.
The objection TO the gas engine for
more than 1000 trees lies in the fact
that more than one outht must be
employed.
Whether the source OF power Is
muscle or gasoline, the spray is put
under pressure by means OF force
pump. satisfactory pump, regardless
OF the power TO he employed, should
have the following points: N) All
parts that come in contact with the
spraying fluid should be made OF
brass, which will not be corroded by
any of them: (2) the air chamber
should be SO large that the liquid win
be delivered in a steady stream, IN.
stead OF In a succession OF spurts; cay
all working parts. especially the valves
should be so made that they can he
easily gotten at and cleaned; (4) parts
should ne go arranged that they will
have the minimum chance of break

particularly to the barrel pump, which
