The management of color is more difficult. When the 

 long duration of the flowering season is considered, it will 

 be obvious that it is impossible to keep up the show of a 

 single border or plot for six months together, and conse- 

 quently, that much of the labor employed in mixing colors 

 is misspent, since plants, as they are commonly arranged, 

 come dropping into flower one after another : and even 

 where a certain number are in bloom at the same time, 

 they necessarily stand apart, and so the effects of contrast, 

 which can be perceived only among adjacent objects, are 

 entirely lost. To obviate this defect, it has been recom- 

 mended that ornamental plants should be formed into four 

 or five separate suites of floweriDg, to be distributed over 

 the garden. Not to mention the more vernal flower, the 

 first might contain the flora of May ; the second that of 

 June ; the third that of July ; and the fourth the tribes 

 of August and the following months. These plants should 

 be kept in separate compartments, arranged either singly 

 or in masses ; but the compartments themselves should be 

 so intermingled as that no particular class should be en- 

 tirely absent from any one quarter of the garden. The 

 May parterres should, however, chiefly occur in the vicinity 

 of the green-house or conservatory, or, when these are ab- 

 sent, in a warm sunny situation. The flowerings of June 

 and July, as being highly showy, should occupy the most 

 conspicuous parts of the garden. The autumnal peren-
