4 .r.An ounce of prevention is worth
a.;pound of cure is an old; saying
that applies especially to the control
of insect pests. Every year many
insects put in their appearance in the
garden and just as: often take their
share of the vegetables grown,
Knowing what the trouble is does
not always mean an available rem
!. edy. The question that troubles us
is how to Mix in the proper proper
tions, enough spray for a few rows
: of potatoes or a small patch Of cab
4 bages, perhaps a gallon or two. The
different state experiment stations in
the u, S., Dept, Of Agriculture Issue
! many useful bulletins on this sub
!, ject But they are all written for
the benefit of the farmer whOs uses
spray in large quantities. The for
mulas and directions given are. for
the fruit grower with his thousands
/ Of trees or. for the. man that plants
! potatoes by the acre; But often the
small gardener must resort to the
] use of pencil and paper to get the
correct proportions for his usei RAJ
/ Their than do this. he either will not:
/ spray at. all or else guess at the
proper amounts. This generally
makes the spray solution so weak
&, that it is not very effective or else
F, it is. so strong or poorly Mixed that
there is danger in burning the fol-
/ iage.
The formulas given below are in
terms most. familiar to the house

Measures Of Equivalents for House,
hold Use. fstt.a4
Two cupfuls of liquid or dry ma
terial equal one pint; four cupfuls of
liquid or dry material equal one
quart; three teaspoonfuls equal one
tablespoonful.
Measurements by weight are the
most accurate, but; as pair OF
scales is not included in the kitchen
outfit of all housekeepers, measure
ment by cup, table or teaspoon are
usually designated. Measuring cups
hold half pint and division into
quarters an dthirds are indicated OF |
their Sides" To measure dry ma
terial, press the material into the
cup or spoon solidly and level with
a knife. All quantities call for level
measurements.
For Plant Lice, Whit Fly, Etc.
Into one quart of warm water
shave one cubic inch of common laun-
dry soap and when dissolved pour
it into two quarts of water and add
a teaspoonful of nicotine sulphate,
forty percent. Shake well to get a
good mixture and it is ready for in
slant use. Care should be taken in
purchasing the nicotine sulphate to
get it of proper strength for if
weaker solution should be used it
will make the spray too weak. 1t
should be applied literally so as to
drench the plants that are to be pro-
tected.
This spray seems to have taken
the place of kerosene emulsion, to
a great extent. as a contact spray.
1t is very effective and easy to pre-
pare. Nicotine suphate can be pur-
chased at most any drug store.
For Scale, Insects. Plant Lice,
Animal Lice, Etc.
From a cake of laundry soap cut '
out a cubic inch, that is, one inch E
each way. Shave it into a cupful of {
soft water and boil for few minutes G
in a thick vessel which will hold 5
he heat for a time. When it is {
dissolved remove from the fire and
pour into it, while still hot, two q
,upsful of kerosene oil. Agitate >
with an egg-beater until h
he oil is perfectly emulsifed, when 4
t will have a creamy appearance +
md will not readily separate from q
he water if allowed to stand. This
S known as stock emulsion and must !.
)e diluted before using. For use as
dormant or winter spray against
Gale insects it should be diluted at =
he rate of one part of the stock .
to ten to fifteen parts of
water, or mix one cupful of the stock +
mulsion in three quarts of water
his more diluted spray should be
sed if there are any leaves on the
liant to be treated and in all cases n
he spray mixture should be kept a
TIRED or shaken while applying. If II
his is not done a good mixture is W
OF maintained which may result in q,

ion is one of the oldest of contact le
