 never liked this butterfly ; and both agreed that 

 they would rather have on their premises one 

 impudent, meddling American copper than all 

 the goatweed emperors in the world ; and yet, 

 perhaps it is hardly fair to bias public opinion by 

 expressing such an unreasonable prejudice in 

 print. 



The caterpillar, like those of the sovereigns, at
