THE bsTEAMING PROCESS IN
gseis SPECTED.
Mr.. C. L. Marlatt, first assistant ento-
mologf4t. United States department of
agriculture, visited the agricultural ed
itor Of The Herald at his ranch on Tues
day. where several hours were spent
In scate and bug hunting.
1t IS almost needless to say that the
visit was, to the editor, most pleasant
and Instructive one.
On Monday, while at Pomona, Prof.
A. ]. Cook asked if the red scale brought
forth their, young alive or laid eggs.
Throltgh the assistance of Mr.. Marriott
we are enabled to inform Prof. Cook
and the public (for we presume if there
had been any published statement of
the TACT, Prof Cook would have
known ity that the red scale (aspdiotus
aurantiil, bring, forth their young alive.
1t is a most interest ting process to watch
them do t. II the process had been
carried on in, England and that grand
old woman, the queen, would extend
to these little creatures the same gen.
crositX that she is alleged to have ex-
tended to human mothers bringing
forth friplets, namely giving them one
pound sterling each, we are certain that
even her erEye ilues would not be suffi-
cient to supply the scale mothers on

Mr.. Marlatt was shown the steaming

ticed at South Pasadena. and previous

nounced 50 per cent, if not all of the
scale dead. ~" 7tfi
Mr.. Marlatt has been in California
about two weeks. but said that he was
anxious to get out of the state, for he

BETTER THAN KEROSENE EMUL-
iAaHop hLc SION
Thekfotowing is taken from the notes
of Professor As5J. Cook in the California
Cultlvator:fpsf IL rssr
"A late Cornell University, New
York. bulletin refers to the fact that the
kerosene emulsion was first made and
used by a. j. Cook as published in the
Michigan Agricultural Report of 1879
This isl corrects There is no earlier
printed'reference to this substance. The
term emulsion, however, was first used
by Mr.. Henry Hubbard. while working
for the department of agriculture. Mr.
Hubbard's experiments were very pains
taking. and he decided upon the formula
now recommended by the department
of agriculture and generally referred
to as the standard emulsion. This gov
eminent formula, however, is defective
in that 1T works imperfectly with hard
water--thatl containing much lime
and in very cold weather, unless the ker-
osene is warm, which is not to be recon-
mended. DR.. Hilgard reported to me
last week that he used my formula as
1t gave the best results, at Berkeley"
Interfering sto Berkeley for a recon-
dot 10y oh hot
he has scarcely caught on" If Pro-
fessor Cook had been present on Tues
day at a conversation held with Mr..
George Clark, the professor would have
heard the following: 1911
Question-You were some time ago
the manufacturer of an insecticide
called Acme. now known as Eureka?
AnswerAYes, sir.
Odd you ever get the authorities
at the agricultural college to try it?
A.-Yes,1 sir; and they gave me a
Recommendations for It,
Q.---Why' don't you use the recommen-
dalton in your printed matter, as you do
those Of other people?
Al would be afraid that to show a
recommendation from these ignoram-
uses would injure the sale of my in
eecticide,
There are three difficulties in forming
the kerosene emulsion: First, when the
weather is cold in forming an emulsion
at all Secondly, when water is hard
of forming perfect or permanent emul-
sion. Third, in using the proportions
of water, soap and kerosene SO that
there Will not form upon cooling, espec-
tally Of the undiluted emulsion, a gela-
tinous mass. If this forms, it has TO be
relocated to reliquify it, and this must
be done before it is diluted and used in
case 1t does thicken. The formula l give
produces d perfect emulsion that does
not thicken either before or after dilu-
ton with any soap that l have tried.
The best formula for kerosene emul-
sion, to be used in California, is as fol-
lows: Dissolve one-eighth of pound Of
hard soap in two quarts of water by
boiling. AS soon as the soap is dissolved,
remove from the fire and while yet boil
ing hot, add one quart of kerosene oil,
stir This most vehemently by use of an
egg'beater, in case only little is needed,
or by use OF force pump in case guam
tity is required, pump the liquid back
into itself. We cannot stir sufficiently
by spoon or stick. A good emulsion re-
sembles rich cream. The agitation takes
from three to five minutes. and if suffi-
Gently violent, the mixture will be per-
manent, l. e., the oil will not rise to the
top. We add to this emulsion nine quarts
of water. This will kill young scale,
plant lice, etc., but will not hurt plants
We find that what is known as dis
ttllate, OF which there are two varieties
in the market. the white and yellow
both products of California petroleum
will make an equally good and effective
emulsion as kerosene and the cost is
mucfisiess, as the following receipt will
