Remedies. — Hand-picking the worms is the most 

 effective remedy for garden patches. Their depre- 

 dations are so conspicuous that it is generally easy to 

 find them. The moths may be destroyed (and conse- 

 quently the deposition of eggs prevented) by smear- 

 ing flat boards in various parts of the field with

molasses mixed with stale beer, to which a little fly 

 poison has been added. The boards should be a foot 

 or two from the ground. Another method which is 

 especially recommended for killing the moths in 

 tobacco fields, is to plant at occasional intervals in the 

 field seed of Jamestown Weed (Datura stramonium) 

 about the time the tobacco is put out. These will 

 come in blossom when the moths appear. If a little 

 fly poison, mixed with sweetened water and whisky, 

 be poured in the long blossoms each evening, the 

 moths that sip the liquid will be killed.
