 the yellow striped bug, that preys upon those plants 

 while young. 



No doubt a plant of tobacco, set in the same way, 

 would answer a similar purpose ; or, perhaps, to sow 

 a few tobacco or onion-seeds in the hill, when planting, 

 would have the same effect ; and the growing plants 

 from these seeds could be taken away, when no longer 

 wanted as protectors. 



Of other substances, sulphur is perhaps the most 

 effectual, as every kind of insect has an utter aver- 

 sion to it. 



Powdered quick-lime is deadly to many insects, and

Calomel is also deadly to insects ; and camphor, and

Afler premising thus much, we shall now speak of 

 insects separately, and begin with the 



Canker-worm. 



The female of this insect comes out of the ground
