234: PARKS AND PLEASURE-GROUNDS. 



it is desirable should be kept in view more fully than 

 heretofore in the formation of this species of garden. 



Territorial arrangements of plants have been recom- 

 mended, and, we humbly think, have received too 

 little attention ; for, being skillfully executed, they 

 would possess a high degree of interest. There are 

 difficulties, it is true, in carrying out the territorial 

 principle, particularly in regard to those exotics which 

 require protection and artificial heat. Still, much 

 might be done with the natives of the temperate and 

 frigid zones, to exhibit the vegetation of particular 

 kingdoms. At least three of the quarters of the 

 globe — Europe, Asia, and America — could be ade- 

 quately represented; and subordinate sections, if ne- 

 cessary, might be made to include the plants of the 

 more important countries, or ranges of continent em- 

 braced in the main divisions. For example, we miglit 

 have a British Flora, a French and German Flora, a 

 Mediterranean, a Russian and Siberian, a North Amer- 

 ican Flora, and various others. Undoubtedly, one of 

 the most curious things in our flower-gardens is to see 

 natives of the Alps and the Himalayas, of Oregon 

 and of the Cape of Good Hope, all growing peacefully 

 and lovingly together ; but in consequence of this pro- 

 miscuous planting, the facts of botanical geography 

 are at once lost sight of, and very often completely 

 forgotten. It is admitted that it would be difficult, or 

 rather expensive and laborious, to carry out the terri- 

 torial system to a great extent; yet it might be within 

 the compass of attainable effort to adopt the principle 

 in part. We should like to see a real Amei'lcan gar- 

 den — that is, one containing only American plants, 

 and not the mixed aflFair which goes generally under
