FART VI. ORNAMENTAL GARDENING. 345 



These scenes are not only pleasing or amusing in themselves/ 

 but, when introduced in a pleasure-ground, by their contrast 

 with other scenes, and with one another, may add to the variety 

 and interest of that species of ornamental scenery. 



A SMALL BOTANIC GARDEN, OR BOTANIC PARTERRE, may 



contain a large- collection of all, or several, of the different fami- 

 lies of vegetables, as an arboretum, frutecetum, harbarium, ar- 

 ranged either by the sexual or the natural systems of Linnaeus, 

 or by the natural system of Jussieu, or any other author. These 

 may be planted either in beds, as is commonly done when the 

 Linnaean system is followed, or in irregular masses when 

 any natural arrangement is adopted. A university botanic 

 garden does not come within the plan of this work. — See 

 Chapter I. 



Hot-houses, in ornamental gardening, are of various kinds, 

 characterized by the modes in which the plants are grown, and 

 the different degrees of temperature employed in their culture. 

 The principles of their formation and management are the same 

 with those already mentioned under Useful Gardening, 

 and therefore do not require to be repeated here : all that is 

 necessary is, to offer a few hints on the different varieties re- 

 quired for ornamental purposes; these are, Stoves, Green- 

 houses, and Conservatories.
