Near the furface they were accompanied 

 with the roots of the burner, and of the bur- 

 net-rofe ; neither of which reached more 

 than two feet deep. 



At the depth of three feet the root of the 

 decaying plant had rotted off; having no- 

 thing but the fibrils above left to fupport it. 



At four feet the vigorous plant reached 

 the top of the rock ; or rather, the loofe flones 

 which lie upon the rock. 



The fields of pafture of this plant were 

 evident. The root was (imply a thong, 

 reaching from top to bottom; tapering from 

 the fize of a reed to that of a crow-quill. The 

 fibrils on the fide were merely hairlike ; ex- 

 cept at about two feet deep, where fome 

 threadlike rootlets were thrown out into a 

 tiiin layer of fomewhat palifh- coloured clay ; 

 and except at about three feet and a half 

 deep a fimilar ramification had been made in 

 a fimilar but paler-coloured earth. At \four 

 feet a general ramification had taken place; 

 the main root there fcparating into large 

 branches -, flriking nearly horizontally ; not 

 upon the top of a hard impenetrable rock 

 (though upon a {lone of about fix inches 

 H 3 over)
