ments of like tenor but the above
are representative of the expert
ences of practically all the farmers
woh have tried the molasses mix

Many different mixtures of cal
cium arsenate, molasses and water
were used all apparently with
similar success. This shows that
the method has not been perfected
and suggests that comprehensive
experiments are badly needed 10

amounts of calcium arsenate and
molasses in the mixture and the COR
rect number of and intervals between
the applications.
We tested here this year many
different mixture of calcium arse
nate, molasses and water and many
methods of applications. All we're
successful to greater or less de-
gree. The rainfall Of this section
was abnolmally frequent and alb
normally heavy from May ID to
August 20. On our best drained
soil we made from rs per cent. to
100 per cent. of an average crop.
On lands less we'll drained we
made from 40 per cent, to 60 per
cent. Our total average yields were
fully two thirds Of normal crop.
On most of our crops we used six
or seven treatments beginning
June IL (Which was at least one
week too late for best results) and
ending August which we now
think was too early to quit.) We
treated several fields on August 81
cellent results. I have before me
a report of the operations on one
Ia acre field treated six times from
June 13 to August at a cost of
$2.53 for materials, $1.51 for la
bor; total cost $4.04 per acre; 81
3-4 pounds of calcium arscnate and
six gallons of mollascs per acre
being used. Twelve bales weigh
ing 6,175 pounds were produced.
Drawing Conclusions
Our experience and that of many
other farmers all over South Caro-
lima and Georgia point definitely to
the following conclusions:
First: A mixture Of about one
pound of calcium arsenate, one
gallon Of water and one gallon of
molasses applied at the rate of
about one gallon per acre to the
young cotton just before the
squares begin to form will destroy
practically all Of the old weevils
on the cotton.
Second: Further applications ex-
tending to the end of the period of
emergence will destroy nearly all
OF the later emerging wcevils.
Third: This viii lprotect the cot
ton crop from serious infcstaton
until around August /, and will al
low a fair crop to be made with
out further treatment. The total
cost of the above treatment will
the labor cost, which is usually
borne by the tenant, will run be-
tween Is cents and and 40 cents per
acre per application.
Our own experience has convinc-
ed us that applications should be
begun again in late July or early
August when further infestation
from neighboring fields begins and
should be continued at least until
the bolls begin to open.
The present supply of calcium
arsenate would, believe, be suf-
ticient to afford excellent weevil con-
troll on every acre of cotton in the
United States if mixed with molas-
ses and water and applied in two to
tour applications, the first to be made
just before the squares begin to form
an dthe last at about the end of the
emerging period.
The overwhelming problem of wee
vii control during the coming year is
the calcium arsenate supply. 1t
