for the same reason. 1t sometimes
happens that an effort is made to
boom certain sections as very favor
able to apple growing because the
cooling moth does but little, if any,
damage. But that is equal to saying
that high colored apples cannot be
raised there, but the fact is never
brought to the front by these boom
ers. This is but a verification of the
old saying that the best things in life
come only where we must make the
greatest effort to secure them.
In these columns not long since l
gave the method of preparing the lime
sulphur wash for the San Jose scale.
This is done by boiling the lime and
sulphur in vat for some two or
three hours. 1t seems that some re-
cent experiments have shown that the
boiling may be dispensed with. This
is done by using flowers of sulphur,
which is mixed into a paste and then
added to the lime while the latter
| is shaking. Two pounds of lime
are used to one of the sulphur. The
sulphur is mixed with hot water and
the lime is slaked with hot water.
The sulphur must be added to the lime
as soon as the boiling water is poured
over it, A strong barrel must be used.
1t is claimed that lime slaked with
hot water will exceed the heat of boil
ing water by 80 degrees. 1t may be
said of this method of preparing the
| lime-sulphur wash that it is not al
ways reliable. 1t has this advantage,
however that it can be prepared with
no of q hni1inO tank Whore
man has but few trees to spray he
can use this method of preparation.
After spraying with the lime-sulphur
wash it may be found that the scales
may be that the treatment is not en-
tirely effectual That may not be a
correct conclusion. 1t has been found
that the effect is gradual and not in
stantaneous The following quotation
| from w. e. BrittOn, state entOmOlO-
gist in Connecticut, is so clear and
gives the reason for this gradual act
ion so we'll, that l consider it worthy
of repetition: "All lime and sulphur
mixtures with or without salt) seem
to have a gradual instead of an in
Simultaneous insecticidal action, and

! list gives regarding the chemical
changes in the mixture. He says that
in boiling, several of the numerous
sulphides of lime, (monosulphide, poly
sulphide, etc., are formed, and these
are put upon the tree, if we spray
while the mixture is fresh. The car
bonic acid of the air acting upon the
mixture that covers the tree sets free
sulphurated hydrogen, poisonous gas,
and unites with the lime, forming
coating of carbonate of lime upon the
tree. The gas is generated slowly
and probably is held by the carbon
ate of lime coating, and also fills the
cavities under the shells or armor OF
the scale insects, thus suffocating
them. 1t is quite probable that the
mixture kills some of the insects by
| it's caustic or corrosive action, but
this effect would probably take place
very soon after the application But
the action of the lime and sulphur
mixture is very gradual and the NOR
tality of the scale insects is much
greater four months after the applica-
ton than four weeks, if it has not
been washed off by the storms" AS to
the mixture sticking Prof. Britton has
this to say: "Salt has little or no
valua either in making the mixture
