ficiently penetrating to kill the in
sect under the scale; if applied in
summer it would kill the tree. In
winter this spray can be applied to a
dormant tree with perfect safety. In
this article We consider the essen
tials Of a good spray pump and the
grades Of ingredients. Blundering
when purchasing the equipment and
material may make spraying expen-
sive and unprofitable.
In selecting a spray pump the or
chardist must be governed by the
circumstances. Cheap tin or copper
pumps can not be used for this spray
nor do We recommend knapsack
pumps for this purpose. A substan-
tial pump with brass working parts
should be secured. 1t should be fit
ted with 25 feet Of hose and in case
of large trees an extension rod should
be used so that all parts Of the tree
can be reached. Light extension rods
can be purchased from any dealer in
spraying apparatus or serviceable
one can be made Of gas pipe with
threads cut at each end to fit hose
and nozzle. Where only a few trees
are to be sprayed the end Of the hose
containing the nozzle may be fasten-
ed to pole and in this manner the
tops of trees can be reached. In all
spraying operations with lime sui
phur wash vermorel or nistry noz-
zle should be used. These nozzles
throw cone-shaped misty spray and
do not become leaky. A Bordeaux
nozzle is unsatisfactory, as it soon be-
comes leaky. When buying Vernon
el nozzles, they are generally sup
piled with several caps having holes
different sizes. The medium-size
hole, which is about 1-16 inch in
diameter, is best adapted for spray
ing this wash.
Where only a few trees are to be
sprayed, a bucket-rump, costing
So, will answer the purpose.
In orchards Of one hundred or
more trees, a barrel-pump, costing
from SIS to $40, is recommended. It
may be fitted with two leads Of hose,
the barrel having a capacity Of fifty
gallons, thus economizing time and
labor.
The 1-2 inch four-ply hose is gen.
orally used. 1t costs about 10 to II
cents a foot. The best quality hose
costs about 16 cents and is the cheap
est in the end. A wire-wound hose,
although heavier, will stand more
abuse, as we'll as much higher pres
sure. Every barrle-pump should be
provided with a good agitator as we'll
as an air-chamber sufficiently large
to insure steady pressure. When the
working parts Of the pump are above
the barrel or tank, it prevents the
parts from becoming rusty and cor
roded. On the other hand, it is often
desirable to have the working parts
in the barrel to facilitate getting
around trees with low, spreading
branches. For large orchards Of sew
eral thousand trees, the pump is
on a wagon tank Of two or
three hundred gallons capacity. Such
a tank costs about $15. A double-ac-
tion pump is recommended for this
equipment in all cases.
Grades Of Lime and Sulphur.
It is recommended that calcium
lime be used in all cases as magnes-
ium lime does not unite so we'll with
the sulphur and furthermore it often
contains Jumps that will not slake.
Such Jumps are nuisance when pre-
pairing the wash. Any grade Of lime
that does not slake completely is un-
desirable. Great care should be TAX
en- to avoid the lime becoming air
slaked. Where it must be kept on
hand for some time it is well to slake
it and keep it covered with water in
a pit.
The two grades of sulphur used in
making this wash are "flour'' and
"flowers. Both grades are salts
factory but as "flour" is about so
per cent cheaper it is recommended.
There are other brands Of sulphur in
the market but frequently are lumpy
