the ingredients.
When sufficiently boiled the con-
tents OF the vat should be strained
INTO the spray tank and diluted with
enough water to complete the for
ihula. Straining is very important
as 1t prevents clo&ging the nozzles.

VIII answer for the strainer if Dor
ueallN nozllcs are used. 1t is not
necessary to heat the water for
dilutlng as the wash is lust as Ell
tcctlve cold. The hot wash is more
corrosive to the spray hose and is
dangerous to the operator in case
OF accidental unCoupling of the
hose.
Many attempts have been made
to prepare self boiling wash bv
using large excess of lime and
depending on the heat of shaking
to effect the chemical change.
Such washes are not successful in
sectlCides and should not be tried.
On large scale sulphur lime is
boiled by live steam. The main
advantage of this method is that
no stirring is required
PreCautions-Never use a copper
implement i'll preparing sulphur
lime. 1t will be quickly corroded.
Similarly the wash furnishes silver.
If sulphur-lime comes in contact
with any lead paint it will blacken
it. This discoloraton can be
bleached by washing with hydrogen
peroxide, but that is expensive.
The air will also bleach it in time.
Pumps used with sulphur-lime
must be washed out each night af
ter using. Pumps with brass work
ing parts will have a sCaly crust
formed over the brass after con
tinued use. Brass nozzlcs are eat
ell and a sufficient supply should
be kept upon hand to replace them.
Sulphur-lime will keep if not eN-
posed to the air. 1t is not necessary
to use it fresh each day, but it is
advisable not to keep too long
Sulphur-lime is caustic to the
skin and may produce ulcers. An
noint the hands and face with
vaseline before spraying. The
horses as we'll as men who spray
should be protected. Use blankets
and hoods of gunny sacking or
canvas.
Sulphur-lime should not be
mixed with paris green, arsenate OF
lead or blue vitriol. These in1ure
the wash. Salt, as formerly used
has no value. If a gas spraying
machine is used, keep the sulphur
lime hot.
