the emulsion. Add five gallons OF
water for a twenty-five per cent emul-

do If two thorough sprayings are given
as advised above. Any ordinary spray
pump will do for this emulsion. but it

"The disadvantage in the soap emul-
sion lis the trouble of mixing, but with
proper kettles for heating the water,
this is not a serious matter
The advantage is that a more even
coat OF oil can DO applied. for there is
not yet on the market a pump that will
give uniform and perfect satisfaction
with the mechanical emulsion. Unless
great care is used the per centage will
be uneven. The pumps are also more
expensive But with these pumps,
kerosene. $50 degrees flash test, cr the
crude oil, is put into one tank and the
water into another, the proper attach
ments Of hose and nOzzles are made,
and you are ready for business. In all
eases a fine nozzle should be used.
Emphasis is placed upon two things
and these are of the utmost import
ance. First: Spray twice year.
Second: Cover every part OF every
tree.
In case the infestation is not dis
covered until the trees are in foliage;
or If on any trees the treatment has
not been effective, a fifteen per cent
kerosene emulsion, either soap or me-
chanical, may be applied at any time
covering the wood fully with the spray
but avoiding the leaves as much as con-
venient
There are other sprays, but at pres
ent the oil seems best and most con-
venient.
THE lime, salt and sulphur mixture
used on the Pacific Coast will give gOOC
results, probably. and may be tried as
an experimentThis mixture is pretty
severe on pumps and must not be- mad'
in copper kettles as it eats this meta
very readily and will destroy a cope
vessel in a few minutes.
