DISEASES OF THE COTTON PLANT. 
Stramonium), a plan adopted in Florida as an effectual 
means of destroying them, and which it is said has suc- 
ceeded to a considerable extent, has been communicated 
by Mr. Jesse Wood, of Mount Pleasant, in that State, 
who says : 
" About five years ago, Mr. Igdaliah Wood, of this 
vicinity, endeavored to poison the fly that produces the 
horn-worm, by applying a preparation of cobalt and sweet- 
ened water to the flower of the tobacco-plant. He found 
some difficulty in consequence of the cup of this flower not 
being in a favorable position to retain the poison. Mr. 
George Sunday next tried the bloom of the gourd-vine, with 
better success. Mr. E. Johnson afterward used the James- 
town weed, which answered the expectation of the most 
sanguine. The preparation consists of about a pint of wa- 
ter, a gill of molasses or honey, and an ounce of cobalt. 
After inserting a quill through the cork of the bottle, he 
let fall a few drops of this mixture into the cup of the 
flower about sunset. As this poison will soon kill the 
stalk of the Jamestown weed, the best plan is to break off 
the blossoms, make a hole in the ground, and place them 
in it. It is thought that the flies find them quicker than 
when left upon the stalks. It is certain to destroy the 
moths, although they frequently live until ten o'clock the 
next day, notwithstanding they are disabled from flying or 
depositing their eggs soon after taking the poison. 
" I consider this discovery of immense value to tobacco 
planters, and, if it or any similar method should lead to 
the destruction of the cotton caterpillar and boll-worm, 
which is highly probable would be the case, it will be of 
incalculable benefit." 
From this statement, it will be seen that, if such a plan 
is really of utility when applied to the cotton-fly, there can
