CHAPTER II. 



OF THE MATERIALS OF REAL LANDSCAPE. 



These may be divided into three kinds — the necessary, or 

 permanent — the occasional, or appropriate — and the fleeting, or 

 accidental. 



SECT. I. OF THE NECESSARY OR PERMANENT MATERIALS. 



These are ground, rocks, stones, wood, lowgrowths plants and 

 grasses, water, and buildings. 



Ground. — Though this material is generally less under the 

 control of art than the others, because the necessary opera- 

 tions are commonly too expensive; yet it deserves to be re- 

 marked, that when ground is placed immediately under the 

 eye, improvements are easily accomplished, and always pro- 

 duce a singular and striking effect — an effect singular, because 

 upon a material which we seldom see altered — and striking, 

 because on one Avhich shews the full effect instantly after the 

 labour is finished.
