Spraying Machinery.

The following is written in response
to numerous iuquiree regarding the
proper spraying machinery suited 10
general work in tie application Of it's

The recently inc casing demcad
throughout the country for spraying
apparatus hns led 10 tho production
III many forms Of force pumps ana
nczzles. Most of these are m~auuracti
ured in tho east, but recently the de-
nnnd in California Tor ouch Apparatus
has made imperative the establish!

The suitability of The rorco pump

The luiBc orchards OF Gal furniu do.
mnnd the use OF pumps of,lnrgc capac-
ity. These permit the use OF two or
moe spray die hargcs aud consequent
ly require un extreme amount OF force
in their management. There is how!
ever little il any cali az yot in Nevada
for machinery permitting su:h wholet

Another extreme is represented in
the small pump manipulated 10y one
hand winIe the other directs the noz-
z!e. Such nre very satisfactory whom
employed upon small plants ard
shrubs Of limited numbers, but fer
orchard use these pumps are utterly
useless. Not only is the required IL

For general farm use tho most
avaiiao!c force pump is doubtless n

required. But one OF the dischar1es

necessary with such substances Ms re-
main in mechanical mixture only, tho
active portion of which will settle ;f
undisturbed. When using other lio.
uids requiring no agitation this dis
charge may DO cut OFF, thus giving in4
creased force to Ito nozzle discharge.
The nest important virtue OF the
pump lies iii the force that cau DO
