After about ten minutes quickly add cold
water to make 100 gallons Of spray. For
smaller quantities mix proportionatey.
KEROSENE EMULSION is valuable for
destroying insects which live on plants by
sucking the juices through a tiny beak, 1t
Is, therefore, known a contact" insec-
tiCide, and made according to the follow
ing formula and directions;
Dissolve one-half pound Of hard soap in
one gallon of boiling soft Crain) water,
When the soap is thoroughly dissolved re-
move from fire and add two gallons Of
kerosene. Agtate this mixture violently
by means of a forCe-pump pumping tho
liquid back upon itself until q thorough
jelly-like emulsion is formed on cooling.
This emulsion is sc per cent oil and must
be diluted before spraying. For dormant

ton may be used and can be prepared by
adding three and one-half gallons of water
to each gallon of stock solution. For spray
ing of plants in foliage to 10 per cent is
strong as should he used Seven per
cent is made by adding eight and one-half
gallons Of water to each gallon of stock
solution, and 10 per cent strength is made
by adding five and one-haf gallons OF
water TO each gallon Of stock solution.
NICOTINE EXTRACT Is another and
nonpoisonous contact spray It can be
bought cheaply In concentrated form. A
homemade substitute may be prepared by
boiling gently for an hour one pound Of
whole or ground tobacco stems in one gal.
Ion of water. This liquid is mixed with
one to two parts of water The spray must
hit the bugs TO be of service
Homemade tobacco decoctlon is made
by stepping (not bollIng) one pound of
tobacco stems in three or four gallons Of
water in covered vessel for two or three
hours. Squeeze and strain Off the liquid
and use as n spray Soap suds added to
the liquid acts as a stcSer and spreader
Nicotine sprays when made properly will
not njure the most delicate plant.
ARsENATE OF LEAD is the safest.
most satisfactory spray material yet COM
pounded, 1t adheres to foliage much longer
during rainy seasons; it will not injure or
burn foliage il remains in suspension bet
ter, and being white aids the operator in
thorough aud complete application Ar
senate of lead may be purchased in dry
powder or In paste form The powder is
not injured by freezing OF drying out and
mixes readily with water, The paste form
is one-half water, costing twice as much for
freight or express charges
Arsenate of lead is used one and one-haIf
to two pounds of powder to fifty pounds OF
water or Bordeaux mixture.
For small use one tablespoonful of the
paste or one-half tablespoonful of the pow
der is used to a gallon Of water or Bor-
deauX. If the latter is used a combined In
scctlciGe and fungicde is developed at one
operation.
PARIS GREEN-One pound TO 100 gall
Ions water must be used with Bordeaux
mixture or with two or three pounds of
lime added TO prevent foliage injury.
For small use, one tablespoonful of Paris
green, three tabespoonfuls of stone lime
and three gallons of water or Bordeaux
with Bordeaux a combined insecticide and
fungicide for all possible pests is formed
HELLEBORE-One ounce to a gallon Of
water Is a mild poison, used where there is
danger Of killing animals. It must be used
fresh.
POISON MASH or bait is used for cut
worms and some other insects which do
great havoc at night in home gardens by
biting on plants at roots. The formula
is one pint bran or cornmeal, one-half
teaspoonful Paris green or arsenate of lead,
chopped up Juice and rind of half an orange,
molasses and enough water 10 make a
dough. Scatter small Jumps in the evening
| about affected area, Highly poisonous, so
do not put in reach Of children, fowl or do
mestic animals. The sour fruit or onion
flavor will deter birds and some animals
| from eating the mash II is good precau-

! the morning. Another method Is to place
a ring Of quicklme, bran and sugar about
| each plant or along the row.
Dh1 SfhAN S-AppllCdllOn ul llStGll-
| cides and fungicides in dry form, known as
| dusting is coming into general use to pro-
| tect various crops, II can now be recon-
| mended for supplementary spraying In
| orchards, and for many truck crops Is
especially desirable. The small grower
| without a spray pump should dust his
crops. busting is not effective for dormant
spraying, but for summer application is

Dry arsenate Of lead combined with sui

| lime, controls chewing insects and many
| ftngous diseases.
Potato growers can use the sprays to
| advantage this season, saving many hours
| of labor. Ten TO fifteen pounds Of dry
lead arsenate is mixed with eighty-fve to
ninety pounds Of finely ground sulphur for
| best results Small proportions OF slakeo
lime may be used as a carrier. small guam
titles can be mixed in same ratio,
