he fays, heave the ground upwards, in many 

 places, into lofty mounts ; and in other parts, 

 where the earth does not follow them, the 

 bare roots rife as high as the lower branches ; 

 and twifUng round form in many places, portals, 

 fo wide, that a man and horfe may ride upright 

 through them*. This indeed is fomewhat 

 higher than pi6hirefque beauty requires ; it 

 borders rather on the; fantaftic. In general 

 however, the higher the roots are, the more 

 picturefcjue they appear. 



To the adventitious beauties of trees, we may 

 add their fufceptibility of motion, which is ca- 

 pable at leaft of being a confiderable fource 

 of beauty. The waving heads of fome, and the 

 undulation of others, give a continual variety 

 to their forms. In nature the motion of trees 

 is certainly a circumftance 'of great beauty.^
