(The soap and kerosene were
mixed together without heating.
A little water was then added to test
its emulsifying power, and this be-
ing satisfactory it was added to the
full amount of water in the tank.
| The agitatOr was then set to work
and a fine emulsion secured. This
was the experiment in which the
Friend nozzle was used at first, but
it was found impossible to keep the
high pressure. the gauge reading
from 40 to ljO pounds. The Friend
nozzle is beautifully adapted to
spraying for the Codling Moth be-
cause of the great breadth of the
spray and its fineness. but it is prac-
tically valueless for use against the
aphis where fineness of spray must
be sacrificed to force. Moreover
with an emulsion it clogs badly.
After the first two rows it was dis
carded and Bean Bordeaux used al
together in subsequent work. The
results of this experiment were very
unsatisfactory as whole. A few
insects were killed, but the majority
were not injured at all. Further,
the foliage was somewhat burned on
the small Jonathan resets, and on
all full-grown Smith Cider.
EXPERIMENT II.---Kerosene
Emulsion. In this case the emul-
sion was made in a different way.
The formula consisted of
Whaleoil Soap------i pounds
Kerosene gallons
Water r----------- 40 gallons
The soap was dissolved by boiling
Dit was found easier to dissolve this
when chopped up into small pieces.)
This was removed from the fire, the
kerosene added, and the emulsion
secured. This was then poured into
the tank containing the requisite
amount of water. Results did not
vary much from those of the first
experiment. There was some burn
ing of the foliay" here also in the
case Of smith Cider.
EXPERIMENT IIl.-Tak- -A-Nap
Soap. Two rows in "A small block of
trees were sprayed with 40 pounds
of Taxa Nap soap dissolved in 200
gallons of water. The effect was
but little better than that secured
with emulsions. Strangely. however,
it appeared to he more effective on
nt h.r
than on Gano and Ben Davis, where
practically no effect could be seen.
EXPERIMENT IN.-Tak-a-N Nap
Soap and Tobacco extract. 1t shouli

Black Leaf Sheep-Dip are trad"
names for essentially the same thin=.

was used:
Tak-a-nap-------O pounds
Tobacco Extract 3 gallons
Water 100 gallons
This made two tanks full. IT,

said that this was completely etfcr-
tive, it WAS very fairly 50. Also
great majority OF Woolly Aphis WA
destroyed by this treatment, wher

had been no observable effects.
EXPERIMENT V.-Tak-A-Nap Soar
and Tobacco Extract. In this exper
ment the quantity of soap was reduce
to 80 pounds for 400 gallons, all othcr
conditions of the experiment being tn.
same. Results appeared to be rathcr
better with the reduced amount of soap
than with larger quantity. especially
on the Woolly Aphis. Whether this
was because the thinner liquid came
through the nozzles better is not Ger
tain, but is suggested as possible ex
PLANTATION.
EXPERIMENT VI.--Crude Oil
Emulsion. This was made according to
the following formula:
Crude Oil............l gallon.
Whaleoil Soap. .......1 pound.
Water. 20 gallons.
The oil is mineral oil recently dis
covered in Utah, but which has not yet
been put on the market. Whether or
not it will be in the near future proba-
bly, depends upon the success of some
of the experiments in which it Is now
being used. As only limited quantity
was available four trees were all that
were sprayed. While the results were
unsatisfactory, yet the limited quantity
which we had to use and one or two &C
cidents which occurred in putting it on
