Make Weekly Inspections.
I'VE would recommend that, after
the conclusion of the series of applica-
tons for the destruction of the early
crop of weevils, the planter make a
careful weekly inspection of his en-
tire acreage and If an occasional spot
is found where a weevil, which has
escaped the early poisoning, is at
work, that the spot be carefully and
Immediately poisoned.
."No- further poisoning should be
necessary until migrating weevils be-
gin to appear, which will be from the
latter part of July to the latter part
of August, varying with the locality.
As soon as these are discovered, pois-
oning should actively begin. again. The
mop method. using about two gallons
per acre of the same mixture previous
ly used, should be employed by the
farmer who cannot afford the machine
illustrated above. For the farmers
using this machine, we recommend the
application of to 5 gallons per acre
of a mixture of s gallons of water,
2 gallons of molasses, and pounds
of calcium arsenate. Applications
should continue about once weekly un-
til cotton begins to open.
"While we believe that poisoning
of the weevil is by far the most i'm
portant single factor for crop produc-
ton in average seasons, we do not
think it is the sole factor. On the
contrary it is definitely known that
certain varieties of both staple and
short cotton are much more productive
than others under weevil conditions.
Earliness of maturity and the early
arrival of the young boil at stage
of toughness and thickness Of hull
which will resist the puncture Of the
weevil, are the two characteristics
which seem to make a variety partly
immune to weevil nttaclts.
Advice to Farmers.
"The farmer cannot afford to
neglect such other important factors
as early fall destruction of the cot
preparation, early planting, thorough

fertilizer containing 300 to, 500
pounds of acid phosphate per acre., a
moderate amount of quickly avail
able ammonia and some potash lex
cept on clay soils). Nor can he af-
ford to plant n greater acreage than
his available labor can tend and
poison and can harvest with reason
able promptness.
"Mr. Coker has devoted almost his
entire time and attention to the sub
ject of weevil control fer the past
seven months and has had the assist
ance of several scientific experts in
these studies. Although we are
spending many thousands of dollars
each year in this and other forms
of experimental work, we are not re-
ceiving one penny of state or govern
nent aid and have no object in ad-
vocating any method of weevil control
except the improvement of TIE condi-
ton of the cotton planter. 1t makes
no difference to us personally what
method is finally adopted, for we are
not promoting any patented machine
or secret nostrum for weevil control.
Method Is Effective.
"We are advocating a method of
poisoning which our experience has
shown to be cheap, simple and reason
ably effective and which, because of
its small requirement of calcium ar
senate, can be widely used.
ave hope further experience will
enable us to improve and cheaper our
control methods; if so We shall let it
be known. We would advise our
friends to secure at once, if possible,
about pounds of calcium arsenate
for each acre of cotton they propose
to plant and to use it in accordance
with preceding directions. Even if the
farmer can secure only one or two
pounds per acre it will greatly bene-
fit him if he will use it in n mixture
with molasses and water in two or

Is Noted Cotton Man.
Mr.. Coker is recognized throughout
the cotton belt as an authority on cot
ton production and improvement. He
is an extensive cotton seed breeder,
having invested thousands of dollars
and years of time in an effort to i'm
prove the better strains of cotton seed
for the southern farmer. He is noted
lecturer on agricultural conditions
generally. and has made thorough
study and has done much expert
mental worh in the matter of boil
wecvil control. He Is likewise n
farmer, scotsman and cotton expert
and is director of the Federal Re
serve Bank of Richmond. He is ack-
nowledged by thousands of farmers
throughout the South as one of mas
terminus as far as farming condi-
tons are concerned.
