210 PARKS AND PLEASURE-GROUNDS. 



east or west may be adopted without any appreciable 

 difference in the warmth. The walls running south 

 and north, or parallel to the meridian, and facing to 

 the east and west, afford secondary climates ; and walls 

 in the intermediate directions have climates varying 

 in excellence according as they approach to or diverge 

 from the south. In the southern parts of the kingdom, 

 where the climate is fine, this subject is of less impor- 

 tance than in the middle and northern districts. Even 

 the difference of a single degree of latitude has a no- 

 ticeable effect. In the neighborhood of London, in 

 latitude 51 deg. 30 min., peaches ripen on a south-east 

 aspect; while at Edinburgh, latitude 56 deg., they 

 require a south wall, a fine season, and other favorable 

 circumstances, to arrive at maturity. When a large 

 extent of wall, with a first-rate climate, is wanted, a 

 parallelogram, with its longer sides facing toward the 

 south, should be adopted, and the southern aspect of 

 the. south wall should be made available by means of 

 a piece of inclosed ground in front of it : when this 

 is not an object of much consequence, a square, or 

 some other more varied form, may be selected. 



Note. — The American reader will perceive that 

 walls, as here discussed, are but of minor importance 

 in the more propitious climate which he enjoys for 

 garden cultivation, as compared with that of Great 

 Britain. — Ed. 



The "Walls. — The height of the walls should have 

 some proportion to the size of the gardes. They may 

 vary from eight to sixteen feet: below or above these 

 heights they are neither convenient nor useful. For 

 these walls, well-made and well-burnt bricks are cer- 

 tainly the best materials, being most kindly to the
