Duval, Fla.—Experiments with compounds, of which Paris green has been the prin- 
cipal ingredient, have been very successful, In every case, except where an inferior 
article has been used, the green has exterminated the caterpillar. 
Gadsden, Fla.—No good results. Killed plants and worms. 
Jefferson, Fla.—Paris green and flour destroyed and drove them away. Those parts 
of the plantations where applied are green and thrifty, while cotton uot so treated is 
destroyed. 
. Liberty Fla.—Paris green, combined with flour or other matter, except water, is a 
umbug. 
“Blount, Ala.—Two or three applications are necessary to destroy the successive broods 
of worms. On light cotton the cost exceeds the profit, and on rank cotton the injury 
produced by forcing through it to sow the poison is a considerable item, unless more 
than one-fourth of the crop could be saved by the application. If worms appear in 
July they produce much injury; but if in September, are regarded as a benefit. 
Greene, Ala.—Kills the worm when it eats the poison. If applied on their first ap- 
pearance will prove of benefit. The poison was only applied once, and killed many 
worms, but did not seem to stay their ravages. 
Marengo, Ala.—Used it on a large scale. Paris green will certainly kill the caterpil- 
lar, if pure and properly applied, either in solution with water or in combination with 
flour, which must be sound. 
Wilkinson, Miss.—Paris green and arsenious acid used, with some failures from im- 
proper application and impure drugs. I am convinced of the efficacy of pure Paris 
green and flour alone. Rows treated with the compound were fresh, vigorous, and 
healthy, while neglected rows were destroyed. 
Noxubee, Miss.—It is much trouble to scatter the compound. Thus far no good has 
been accomplished. 
Avoyelles, La.—Paris green was used to a limited extent in this parish, and when 
properly mixed and applied was a triumphant success. ‘ 
Claiborne, La.—Used patent remedies and killed worms and plants. Made it weak, 
and killed neither worm nor plant. 
Austin, Tex.—Numerous experiments made with patent remedies—effectual in de- 
stroying the worm, but retarded the growth of the cotton. An unpatented combina- 
tion, increasing the amount of flour, destroyed the worms without injury to the plant. 
The application must be made before the bolls open, and in no case after, as if dropped 
on the cotton it becomes dangerous to picker and ginner. 
Fayette, Tex.—Quite a number of experiments, and all of them with good results, 
both with dry preparations and arsenical solutions. The effect does not appear at 
once, but is seen in from twenty-four to forty-eight hours. There has been much pre- 
judice, but all will fall in next year; and, with a favorable season, we expect to take 
a bale of cotton from an acre. Cotton is cleaner where the green is used. Arsenical 
solution the cheapest mode. 
Fort Bend, Tex.—Experiments varied and extensive, chiefly with Paris green and 
flour, 1 pound of Paris green to 20 or 40 pounds of flour, one to thirty being best pro- 
portion. Satisfactory; expense being about $5 per acre. 
Freestone, Tex.—Mixing the green with flour or other powders has not succeeded so 
well as the solution, and cannot be administered so cheaply or thoroughly. 
Montgomery, Tex.—Paris green mixed, either with flour, lime, plaster, or very fine 
sand even, applied inthe morning, from daylight until an hour after sunrise, while the 
dew was on the plant, has been universally efficacious. Arsenic in solution has also 
been used, but with little effect. It burned the leaf and caused the squares to fall. 
2. Proportions and mode of application—The mode and time of appli- 
cation, both of arsenical mixtures and solutions, are indicated by a se- 
lection of representative extracts, as follows : * 
Jones, N. C.—One to twenty-five. Sifted from a tin vessel having a perforated bot- 
tom, and attached to a staif 10 feet long. One or two applications sufficient. Cost, 
$1.50 per acre. 
Craven, N. C.—One to twenty-five. Shaken on to the plants from a box with a long 
handle when the dew was on the plants. One pound of arsenic to eight gallons of 
water was equally effectual. One pound of Paris green to ten pounds flour destroyed 
the leaves. 
Richland, 8. C.—One to twenty parts of flour. 
Jefferson, Ga.—One to twenty-five. Killed the forms and young leaves. 
Jefferson, Fla.—One to twenty-five. Should be applied at night when the wind is 
down and the dew is on the leaves. It must be repeated after a shower, or it will be 
rendered useless. 
*Where no other substances are mentioned, Paris green and flour by weight are un- 
derstood.
