152 PARKS AND PLEASURE-GROUNDS. 



water pipes as means of heating walls. These pipes, 

 when placed within internal cavities, unless they be very 

 numerous, and their sides extremely thin, emit a heat 

 too feeble to produce an appreciable effect on a large 

 surface of wall. 



The Fruit Garden. — This department is so frequently 

 and so properly united to the kitchen -garden that it 

 scarcely requii'es a separate notice. The site and soil 

 which suit the one will generally be found appropriate 

 to the other. When orchards are planted apart from 

 the kitchen-gardens, a warm, dry, and sheltered locality 

 should be selected for them. In the more northern or 

 midland districts, the outer sloping banks — but not the 

 level holms — on the sides of rivers, are found to be 

 singularly propitious to the growth of hardy fruit-trees. 

 Orchards, when not very artificially planted, and when 

 furnished with proper accompaniments, may be made to 

 harmonize well with the general scenery of the park and 

 pleasure-grounds. 



The Forcing Garden. — Fruit and vegetables are said 

 to h^ forced when their growth is accelerated and their 

 maturity perfected by means of glass and artificial heat. 

 The forcing-garden, then, requires a number of glazed 

 houses or other structures of more or less complicated 

 construction. It is usually mixed up with the kitchen- 

 garden, or what is better, partly attached to it in a 

 separate compartment. The vineries, peach-houses, 

 pine-stoves, and occasionally a greenhouse, are com- 

 monly placed on the south side of the north wall of the 

 kitchen-garden, while the furnaces, sheds, and other 

 necessary offices occupy the north side of the same wall. 

 In such cases, when the nature of the ground permits.
