POEEST LAWNS AND 3?0KEST HEATHS. 305 



pend for their principal aid, I sliall dwell a little 

 on this copious subject, and shall consider its 

 most pleasing circumstances under the two heads 

 — of such as are ^permanent, and such as are in- 

 cidental. 



But before I enter on the subject, it may not 

 be amiss to remind the reader once more,* that 

 as the vast scenes of extensive forests, which we 

 are now considering as distances, are not subject 

 to art, the idea of suggesting rules to alter and ' 

 improve them is absurd. All we mean is to 

 endeavour to teach the eye to admire justly, and 

 to apply to artificial landscape those observations 

 which occur in natural : for the source of beauty 

 is the same in both.
