out of the grounds i By the ad of November, 1778, 

 this fmaJl rope had thrown out fhoots, feveral of 

 which had extended themfelves to the diftance*of 

 eight feet^ feme had even thrown up leaves px 

 feet from the original root. Mod of thefe fhoots 

 which had thus far extended themfelves were about 

 fix inches under ground — others had penetrated -to 

 the depth of two feet and a half; the whole toge- 

 ther, when dug up and walhed from the earth, 

 weighed four pounds. 



In the fpring of 1779, contrary to my expedta- 

 tion, this thiftle again made its appearance on and 

 about the fpot where the fmall piece was origi- 

 nally planted. There were between fifty and fixty 

 young heads, which muft have fprung from thofe 

 roots, which had penetrated deeper than the gar- 

 dener was aware of, although he was particularly 

 careful in extrading them. 



From thefe experiments it appears deducible, 

 that no plants are more eafily deftroyed than the 

 generality of thirties, or with more difficulty than 

 this one 5 there being no foil, however poor, in 

 which it will not vegetate, nor earth fo ftifF but it 

 will penetrate; in proportion, however, as the foil 

 is rich, will be its increafe.
