SPRAYING MACHINERY.

to inquiries regarding the
proper spraying machinery suited 10
general work in the application of
insecticides and fnngicides.
The RECENTLY increasing demand
throughout the country for spraying
apparatus has led to the production Of
many forms Of force pumps and noz-
zles. Most o. these are manufactured
in the east, but recently the demand in
California for such apparatus has
made imperative the establishment
on this coast Of manufactures and
agencies for spraying machinery Of
the moat approved patterns.
The suitability of the force pump
employed il dependent upon. the
nature of the work To be accomplish
cd. The large orchards Of California
demand the use Of pumps Of large
capacity. These permit the use of
two o more spray discharges and
consequently require an extreme
amount of force in their management.
There is however little II any call as
yet.in Nevada for machinery permit
ting such Wholesale work.
!. Another extreme 10 represented in
the small pump manipulated by IA
hand while the other'directs the nozzle.
snch are very, satisfactory when rm-
ployed upon small plants and shrubs
Of limited numbers. but for orchard
use these pumps are utterly useless.
Not oHly 10 the required labor undnly
~jncreased. but worst Of all the spray.
If il reaches the upper branches at'all,
has little or.no force as il does so.
For general farm use the most avail
able force pump is doubtless one that
will keep two discharge pipea Of !
inch hose constantly filed with consid.
cradle pressure. To run such = pump
the labor Of one man will be required.
But one of the discharges need b.
used in spraying proper, the other
with partially obstructed outlet may
be directed into the supply receptacle
- an sgitator. This IL necessary with
such substances as remain In nlecllan-
icak mixture only. the active portion
of which will settle il undisturbed.
When using other liquids requir-
ing no agitation this discharge
may be cut of, tlus giving Increased
force 70 the nozzle discharge.
The most important virtue Of the
pump lies in the force that can be
impaired to it's discharge. Herein lies
q great part Of the secret Of successful
spraying. To aid this, A.inch hose is
greatly 10 be preferred cver finch
hose which is also much heavier and
more cumbersome. For orchard work
twenty-five or thirty feet of hose IL
none too much. To nj part of she
spraying outfit is greater importance
due than 70 the nozzle and its use.
Upon these, aided by the proper force
from the pump, is dependent the thor
onghness with which. the work Of
spraying a be accomplished.
In general the best nozzle 10 that
which resolves the stream into q fine
mist which still retains a considerable
pant Of the force impaired by the
pump. It will be seen that such a
spray will extend at most but few
feet beyond the nozzle. Experience
has demonstrated that to obtain best
results, the nozzle must be held close
to the point of attack. To meet this,
the modern spraying outfit includes
an Hextension" which consists Of q
light gas-pipe six or eight feet long
encased in bamboo. This connecting
the hose and nozzle permits the latter
10 be brought close to the uppermost
branches where the work may be as
thoroughly done as below. For tenn
porary use, the Extension" may be
replaced by an ordinary bamboo pole
