EXPERT DECLARES
National Campaign Director
Sees Possible Victory by
Using Rags to Destroy
Eggs Of Cotton Pests

The unique method of controlling
the boil weevil by N-rays stored IN
chemical salts and applied by adj
hesive mixtures to the hollis and
squares of the cotton plants to ster-
ilize the eggs of the insect, was sug.
gested in an address by DR.. Miller
Reese Hutchinson at Tuesday after
moons session of the National Cot
ton Conference for Boil Weevil Con
troll. in session at the Baptist Taber-
nacle.
DR.. Hutchinson, who is the direc-
tor of the national campaign against
the boil wcevil. declared the enor-
nous rate of reproduction of the in
sect, about twelve million being prop
agated by one pair in one season
was enc of the chief reasons why
it was so difficult to fight, and sug-
gested that anything that reduced
this rate of reproduction or prevent
ed propagation would be of great
value in controlling the cotton pest.
II am now having experiments
performed in my laboratories in New
York with a method Of using this
xterilizing agent through absorption
of X.ravs in chemical salts" he said.
cit is a scientific fact that certain
salts possess the property of absorb
ing N-rays and emanating them
slowly. BY combining such salts
with binder and applying them to
the bolls and squares OF the cotton
plants, the X-rays should sterlllze
the eggs of the weevils and prevent
them from Matching. The intensity
of the X-ray emanations would be
too small to cause any injury to hu-
man beings or animals"
Conference Nears End
The conference was to reach its
elimination with an address Wed
nesday evening by DR.. Hudson
Maxim, Observation-Disclosures in
ventor and scientist, on Man or
Bug-Which Shall Inherit the
Earth?'
Important developments, far
reaching in their potentialities, fea-
tured the opening sessions Tuesday
and Wednesday every one Of the
Several hundred representative plant
ers and business men here for the
conference was bending his efforts
toward a definite organization for
the national campaign for a coop
erative "war of determination"
against the cotton pest.
DR.. w. D. Hunter, entomolog1st
in charge Of southern field crop in
sect Investigations for the depart
ment of agriculture, presided at
Wednesday mornings session, DR..
Miller Reese Hutchinson being en-
gagged in conference relative to the
definite organization of the national
campaign against the weevil.
Arsenate Experts Speak
DR.. Hunter also delivered on ad-
dress on the subject, 1.-THE Govern
ment's Thirty-Year War on the Boil
Weevil," reviewing the known
methods of controlling the pest in
Guiding the use of calcium arsenate,
and declaring that the federal gov
eminent always welcomed the AID
of any person or organization in the
conduct of its warfare on enemies
of plant life.
The shortage of calcium arsenate
and the possibility of increasing the
supply in America were discussed by
Howard Ambruster and Bradley
Stoughton. both of New York, inter-
nationally known authorities on the
use of that poison.
Their discussions dealt largely
with the technical process of making
calcium arsenate from arsenic and
similar chemicals and proposed
methods of making it from other
substances.
Several of the better known
methods of fighting the cotton pest
other than calcium arsenate were
discussed.
J, V. Cochran, of Marietta, who
claims to have produced a boil
weeviI resistant cotton, explained
mis- method ard submitted specimens
of his product.
W. S. Cox, of College Park, presl-
dent Of Cox college, discussed the
use of poison gas in boil weevil cor
troll; David r. Cocker. Of Huntsville.
S c.. talked on molasses-arsenate
poisons, and L. D. Hill, Of Cough
Ga. originator of "HilPs Mixture -
told of his process, which he said.
had been evolved after five-year
fight with the cotton pest.
Other speakers Wednesday after
noon were to be w. w. Long, dI-
rector of state extension forces Tor
South Carolina; Dan Z. Gray, d.
rector of state extension for Ala
bama; J. J. Brown, commissioner OF
agriculture for Georgia; Frank H
Barrett, of Barrett & Co, Augusta,
and c. E. Hutchinson.of Mounty Hol-
Iy, S. c., president of the American
Cotton Manufacturers association, on
"Facing the Situation From the
Standpoint of the Manufacturer"
DR.. Maxim was to be the only
speaker Wednesday evening.
At l o'clock Wednesday DR.. Hutch
inson, George NJ. Shut, president of
the New York cotton exchange; Paul
r. Pflieger and Henry H Royce,
members of the exchange; DR.. Max
i'm, DR.. Hunter, C. E. Hutchinson,
J. S. Cassells, of Montgomery, vice
president of the Interstate Cotton
Seed Crushers' association; J. S.
