hole is made through the pole near each end, the holes being stopped 
with plugs either of wood or cork. These holes open into the bags, and 
through thern the bags are filled with the insecticide used. This dis- 
tributor is generally operated by a darkey on a mule and going at a 
brisk trot, the vibration being sufficient to shake the insecticide from 
the bags and distributing it very well. This duster can be rigged up 
at very little trouble and expense, and forms the most simple appara- 
tus for the distribution of dry poisons that I have yet seen. It is 
needless to say that it can be used to apply dry insecticides to plants 
other than cotton. Used in the cotton fields four rows are treated at 
a time, the bags at each end of the pole being held over the space be- 
tween the rows. At first thought one might think that in this way 
much of the insecticide would be wasted by falling upon the ground 
between the rows ; but such is not the case, for when the cotton is 
nearly full grown it so completely covers the ground that there is little 
waste. 
Another apparatus used in the cotton fields for the distribution of 
dry Paris green is the Eoach poison distributor, manufactured by J. 
P. Roach, Vicksburg, Miss. This machine is used upon many large 
plantations, but most planters use the above-mentioned cotton dry 
poison duster, as it is so cheap and easily operated. The Eoach dis- 
tributor sells at about $60, putting' it out of the reach of the average 
cotton- grower. When the Eoach distributor is used the Paris green is 
diluted with about ten parts flour or lime, while in using the cotton 
dry poison duster preference is given to undiluted Paris green. About 
10 acres can be gone over in a day with the cotton dry poison duster 
and about 30 acres when the Eoach distributor is used. 
While the Aletia could be destroyed by many insecticides other than 
Paris green or London purple, yet these are the best for this purpose, 
and these are much more easily applied in the dry form than when 
mixed with water. Insecticides mixed with water do very well on a 
small scale, but when several acres are to be gone over dry insecticides 
are to be preferred, owing to the difficulty of getting the water in the 
field and the added trouble of hauling it about. 
THE COTTON BOLL- WORM. 
The remedies for the Cotton Boll-worm are far less satisfactory than 
the remedies for the Cotton Leaf- worm; for the former, owing to its 
working within the boll, cannot well be reached from the outside by 
the application of insecticides. The first brood of Boll Worms is pro- 
duced upon corn soon after it is up, where it is known as the "Bud 
Worm." Here it often does considerable damage, and when the corn 
becomes older and the leaves unfold, it readily shows where the worms 
have been at work. The second brood attacks tomatoes, and between 
the worms and the tomato rot in some years it is impossible to raise a 
crop. I am inclined to think that the worms get the credit of destroy-
