As is no doubt generally known, the boll-worm is the same 

 thing as the corn-worm. It often migrates from the corn- 

 field to the cotton field, as soon as the ears of corn begin to 

 harden, and then eats its way into the cotton boll. In mi- 

 grating it frequently also eats the leaves of the cotton to a 

 slight extent. 



The adult moth deposits her eggs upon the leaves of the cot- 

 ton plant, and the young crawl to the bolls into which they eat 

 their way, but frequently in doing so, they eat of the leaves. 

 It has often been said that the boll-worm feeding upon the 

 inside of the boll, as it principally does, cannot be poisoned 

 by ordinary means. However, from what has been said, one 

 can easily see that if there be poison upon the leaves of the 

 cotton-plant when the boll-worm migrates to it from the 

 corn, or when the young are hatched from the eggs laid upon 

 the cotton leaf, that those worms that do eat of the leaf, 

 will be poisoned. Hence the poisoning of the leaves for the 

 cottou-leaf-worm will also greatly lessen the number of boll 

 worms; and an application of the poison at a time just 

 before or as soon as the boll- worm begins to migrate from 

 the corn, will save much money. The poisoning for the 

 third brood of the cotton worm and of the boll worm may be 

 done simultaneously. The application of the poison for 

 the boll-worm is accomplished in the same way as given for 

 the cotton-worm. 



Perhaps the most widely used method of destroying the 

 boll-worm is to trap the adult moth. The moth is not only 

 attracted by light, but is also attracted by sweets. Hence 

 the placing of lanters in basins of some liquid about the 

 the field, or the placing of simply basins containing molas- 

 ses and vinegar in the proportion of 4 parts of vinegar to 

 1 part of molasses, will catch large numbers of the moths. 

 They are attracted by the odor of the mixture, and in trying 

 to sip it, they fall into the liquid and cannot escape. Since
