Ohs. This, which is considered an exceeding- 

 ly troublesome weed in England, has made its 

 appearance in some parts of Pennsylvania, and proves to be a nuisance 

 not easily abated. It has hitherto resisted all attempts to get rid of it ; 

 Don, in his General System of Gardening, &c., says that " being a great 

 creeper it cannot be admitted into gardens, for after it gets hold it is next 

 to impossible to eradicate it again." The leaves are said to be used in 

 the same manner as Parsley, which accounts for Don's cautioning against 

 introducing it. Such an invader should be carefully watched and its 

 spread arrested.
