 tree or wall, as we ourselves do of a walking- 

 stick, when old age or infirmities tell us that we

 on Grongar hill : — 



«' Whose aged walls the ivy creeps, 

 And with her arms from falling keeps : 

 So, both a safety from the wind

There can be no doubt as to the real source 

 from whence ivy draws life and vigour : from

 To be convinced of this, we have only to inspect 

 it narrowly on a living tree, and then pay the 

 same attention to it upon a dead one, or upon 

 any stump deprived of vitality. Be our eye as 

 keen as that of the lynx, we shall not be able
