The Cotton Worm.


The farmers throughout the Cot
ton States should take, measures in
time to destroy the cotton worm.
Prof Riley, the distinguished ento-
mologist, says there is no excuse
for farmers suffering from the raw
ages of the worm; that the worm
can be eff'ectually and cheaply ex-
terminated by timely application of
London Purple, the most effective
poison in use. Ofthis poison, Prof.
Riley said, and he is the highest
authority on this subject in the
country, speaking at the Cotton
Exchange, at Mobile, on the Cotton
Worm:
owe want someting cheaper and
less dangerous than Paris Green. |
beheve it is already in our power
to reduce the cost of killing the
worms fully one-half to two thirds
by the use of London Purple, one
pound of which in barrel of wa
ter can be more eff'ectually sprin-
kled or sprayed on the plant than
Paris Green, by virtue of its greater
fineness.'
And in letter to the New Or
leans Democrat, September II,
1880. he said:
''The testimony in3 ard to it is
very genera ally favorable the present
year, as | anticipated would be the
case from the experiments we made
a year ago. Pound for pound it
should be made to go twice as far
as Paris Green, i. e., pound of
London Purple is sufficient to
eighty to one hundred gallons of
water and if used dry should be in
proportion of one to forty parts of
the diluted"
And again in Bulletin No, :, of
the United States chronological
Commission, he said:
Like Paris Green it is not solu-
bic, but is much easier kept sus-
pended in water than the former.
London Purple has this farther ad-
vantage over other arsenical COM
pounds hitherto employed. It's
finely pulverized condition seems
to give it such penetrating power
that, when used in liquids, it tints
the leaves so that cotton treated
with it is readily distinguished at a
distance, the general effect being
quite marked as compared with any
OF the other poisons similarly ap-
piled. 1t seems also to be more eff
fectually absorbed into the sub
stance of the leaf, and is therefore
more persistent. At the same time
experience shows that it does not
injure the squares any more than
Paris Green. The cost of DESTROY
ing the worms by this powder is
reduced to such a minimum as to
depend mainly on the labor and
the other ingredients or dilutents
employees, in other words, that
while the planters as heretofore
were obliged to pay as much as one
dollar for the first cost of the active
poison needed for one acre, and
never less than fifteen cents, he may
now obtain it for from three to FIVE
cents"
We would suggest to Oranges
and Co operative Associations to
secure large supplies of London
Purple in time and be ready to de-
stroy the worm on its first appear
ance. They would do well to write
to the manufacturers, whose adver-
tisement appears on our third page,
for prices, &c, and secure supplies
that will be adequate for the wants
of their respective sections. The
indications now are that the worms
will appear sooner than usual, and
farmers should be prepared in time
There is no good reason why sin
gle bale of cotton should be lost by
the worm. The remedy is at hand
and it will be short sighted policy
if farmers fail to apply it.
