The Spramotor has an air pipe run.

which. as the pressure varies. operates
a clutch on a jack. engaging 1t when
the pressure lowers to It's pounds. and

over 200 pounds.
The De Laval Dairy Supply company
Is now featuring the Alpha automatic
spray outfit. which has Myers duplex

Incorporated on the plunger connecting

the device disconnects the operation of
the plungers without interrupting the
driving power, and again permits them
to resume operation when the pressure
falls below this point.
Nozzles-Next in Importance to the
pressure regulation. which insures uni
form pressure to the nozzles are the
nozzles themselves. Without uniform
pressure a good nozzle cannot do uni
formly good work. but a poor nozzle
will not do good work under any cir.
cumstances. A poor nozzle will de-
stroy any possible combination Of good
elements back of it. Nozzles should
be selected according to the work to be
done. The great variety of nozzles on
the market can be grouped into three
main classes. as follows: Solid stream
nozzles, which do not interest the fruit
grower; vermorel or eddy chamber
nozzles; and Bordeaux or spatter spray
nozales.
The Vermorel class of nozzels Is
more used than all the other forms
combined. These all more or less en-

chamber it is given strong rotary

spray. In this class come the Ver-

Mist. Mistry. Cyclone. Fembro. Self
Cleaner. Non Clog. Atomic. DuSpray.
and many others. The Hardie Hilo.
Champion Variable. Hurst Skill,
Cushman Adjustable, and the Brown
Atomic have attachments for adjusting
them to throw driving spray or a
mist. at the will of the operator.
The Bordeaux class consists Of those
nozzles in which solid stream strikes
an angle obstruction and is broken
into fan shaped mist. These'are used
where driving spray is desired and
include the Deming Bordeaux. Gould's s
Seneca, Bean Clipper, Hardie Biz
zard, Bean Bordeaux, Gala. Myers
Way, Field Niagara. and numerous
others.
Extension Rods Since the nozzles
described do not have carrying power
sufficient to reach the tops of high
trees or work against the wind, 1t is
requisite that extension rods be used to
get the nozzles close to the parts Of
the tree to be covered. These rods
are made in various lengths, and of
different materials. First Of all they
should be light, serviceable, stiff, and
of the required length for the work at
hand. The bamboo has now displaced
the gas pipe and other rods and con.
sists of aluminium or brass tubes run
ming through bamboo poles. The bam-
boo pole should be securely fastened
to the tubing so that it will not slip on
the tubing. The clamp ends should
take up the strain Of the dragging
hose and should be threaded on the
tubing, not soldered. SO that when a
bamboo splits up. they can be Assem-.
bled on new bamboo pole.
Shut Offs-In order to control the
flow Of the liquid through the bamboo
poles they should be fitted at the lower
end with shut off that is easy, quick
in action, and leakless. LeakIess. stop
cocks are listed by all spray manu-
facturers which are constructed along
similar lines. There are several angle
shut offs made which attach to the
hose at as degree angle and thus off,
set the sharp bend which causes hose
to wear out so quickly few inches
from the shut off.
The Jasmin controller shuts off by a
quarter turn of wood handle. the
hose hanging down at the proper an
gle. The Hardie angle cut off is
opened or closed by the slightest touch
on handle. the movement of which is
less than Z inches. II will stay open
from the pressure and closes with a
snap where 1t is also held by pressure.
The New Friend double ball cut off has
quick detachable seat, Ia quick and
positive in action and allows the hose
to hang naturally.
Hose and Hose Fittings-When it
comes to selecting hose leave the mat
ter in the hands Of experts and deal
with only the most reliable spray out
filters. The writer has found it Is
easier to hold up pressure with half
inch hose than with three quarters and
believes in buying the very best grade
of hose on the market In the matter
of hose fittings experience has taught
him that the Stay There hose fittipgs.
