2. In what proportions, and in what mode, time, and frequency of application haye 
‘experiments been made? 
3. Have any injurious effects of the poison been observed, either upon the plants or 
the soil, or in human poisoning in its application, or in the destruction of beneficial 
insects, as bees, &c.? 
4, Have you used any other remedies, or means of extirpation, such as fires or torches 
in the fields, to destroy the perfect moths on their first appearance, and with what suc- 
cess ? 
Returns have been received from one hundred and seventy different 
counties in the cotton-growing States, Alabama and Texas being repre- 
sented by the most numerous and complete statements. Of these, one 
hundred reported that no experiments with Paris green, or arsenical 
preparations, had been tried ; many were from counties in which little 
cotton is ever grown, and others were from counties where the worms 
have never appeared. 
1. Efficacy of Paris green—Of the seventy returns reporting actual 
experiment a large proportion, at least four-fifths of all, declare the 
success, either full or partial, of the application of mixtures of Paris 
green or other arsenical compounds, when they are properly applied. 
Some are content with the simple declaration that it is an effectual 
remedy. Where it is most generally used it is most approved. In New 
Iberia, La., where a machine that will powder 15 to 18 acres per day is 
in use, it is said that fifty planters have found it successful. In Wil- 
kinson, Miss., where a simple compound of Paris green and flour was 
used, “rows treated with the compound were healthy and vigorous, 
while neglected rows beside them were destroyed.” In Landry, Tex.,* 
‘‘one application of Paris green in solution resulted in ten additional 
bales in a field of 35 acres, over the rate of production in other fields 
where none was used.” A similar result is reported from Montgomery, 
Tex., by the use of Paris green mixed with lime or plaster, or even fine 
sand, where “ a neighbor has picked already ten bales of 500 pounds 
each from 13 acres, while freedmen on the same farm lost their whole 
crop by refusing to use it.” The correspondent in Worth County, Ga., 
declares it ‘‘ was death to everything that eats the leaves that have 
been sprinkled.” Some correspondents enjoin the necessity of repeated 
applications to meet the appearance of successive broods of worms, as 
enough are left after the most careful application to perpetuate the 
noxious race. In some cases, caution is suggested not to make the ap- 
plication after the bolls are open, lest it become “‘ dangerous to picker 
and ginner.” In the cases of failure mentioned there appears no evi- 
dence that the application was properly and persistently made, and 
with a pure article of Paris green. In some cases where it killed both 
worms and plants it is very evident that the proportion of Paris green 
was too large or applied too heavily. 
The following extracts representing different phases of the experi- 
ment will illustrate the tenor of the returns on this subject: 
Craven, N. C.—Has been used in the county. Checked the worms at points where 
applied. Rains were frequent, labor scarce, and the experiments not continued, and 
the cotton was eventually damaged. 
Beaufort, N. C.—Have heard of but two instances where Paris green was used to 
stop the ravages of the worm, and in both cases without benefit. 
Calhoun, Ga.—Paris green has failed, though from 7 to 8 pounds of the green were 
applied to the acre every two weeks. 
Jefferson, Ga.—The remedy worse than the disease. It occasioned more loss of forms 
and young bolls than the insect. 
Macon, Ga.—Patent remedy used, but not successful. Used about 25 pounds on eight 
acres. 
Talbot, Ga,—Experiments too limited to furnish an opinion—and mainly with arsenic 
in solution. It kills both plant and insect.
