Further, the development of the cotton-seed oil industry has been an 
important factor. In earlier times rank-growing varieties of cotton, 
producing few seeds, but of long fiber, were grown. Now that cotton 
seed is worth from $9 to $15 a ton, smaller varieties of cotton, with a 
shorter fiber and a higher proportion of seeds, are more popular. The 
fields are thus more open, and not only afford a better opportunity for 
remedial work when necessary, but also show plainly the first ‘“rag- 
ging” of the leaves and prevent the worms from working in numbers 
comparatively out of sight until one or more generations have devel- 
oped and the moths have become sufficiently numerous to lay eggs for 
the old and greatly feared “third brood.” These points and others 
have already been reported by Mr. EH. A. Schwarz, of this office. His 
article is a result of observations made upon an official trip through the 
cotton belt in the summer of 1894. At many points he found the sen- 
timent among planters to be that the cotton-worm question is solved. 
As a result of these observations and of the reports of Professor At- 
kinson in Alabama and Professor Tracy in Mississippi, as well as from 
conversations had with a number of influential cotton planters and 
correspondence with others, we are quite inclined to believe that the 
simple method of using undiluted and dry paris green powder which 
has sprung up throughout the South is probably capable of maintain- 
ing present conditions. So far as we know, the large machines recom- 
mended in the Fourth Report of the Entomological Commission have 
never been built and operated by planters. 
The distribution of dry paris green from two bags held at the ends of 
a pole over the back of a horse or mule is a process which has developed 
apparently spontaneously. At least ten years ago the process was 
described to the author in a conversation with Hon. Charles E. 
Hooker, Member of Congress from the Seventh district of Mississippi. 
Writing in July, 1890, Prof. G. F. Atkinson, of Alabama, spoke of it as 
a “recent” method. The Mississippi Experiment Station, in June, 1890, 
described the method as one which had been recently developed. 
Prof. J. S. Newman, of Auburn, Ala., used the process as early as 1887. 
It is quite probable, however, that this method dates back to early in 
the seventies. The method is described by the Mississippi Experiment 
Station as follows: 
Make two sacks of heavy cloth, each about 10 inches long and 4 in diameter, open 
the whole length of one side and firmly sewed at the ends. We have found 8-ounce 
osnaburg the best cloth for the purpose. Take a strip of oak or other strong wood 
about 1} by 2 inches and 5 feet long, and bore a 1-inch hole 5 inches from each end. 
Tack one of the sacks to each end of the pole, fastening one of the edges of the 
opening to each of the narrow sides of the pole. 
The sacks can be filled by pouring the poison through a funnel inserted in the 
holes through the pole, and distributed by riding on horseback through the cotton 
rows, dusting two rows at atime. A little practice will enable one to do this work 
very evenly, and care must be taken not to allow the sacks to touch the leaves when 
wet or the poison will not pass through. When the sacks are freshly filled a very 
slight jarring will shake out a sufficient amount of the poison, but when nearly
