of necessity be, we may quite properly introduce plants 

 from all regions, and grow them under as natural conditions 

 as is possible by artificial means. There we may have lux- 

 urious water-plants from the tropics, as the lotus, growing 

 naturally in ponds and lakes ; and alpine plants flowering 

 freely on the sunny slopes of a rockery not far away. The 

 impression will be as pleasing as if the combination had 

 been made by nature itself. But when the garden is to be 

 a part only of a wide landscape, then it should be in entire 

 harmony with the whole, of which it possibly is the bright- 

 est and most beautiful spot. 



The illustrations to this chapter give a fair idea of the 

 correct curvature of roads and walks, and the picturesque 

 outlines of shrubberies and other plantations. Drives and 

 walks must be as direct as possible, no bends or curves 

 being made simply for their own sake. A drive is natu- 

 rally led around a knoll or hill and not across it, for the 

 grade would be too steep and the outline too stiff and 

 formal. In crossing a stream it must be done at right 

 angles, not obliquely or lengthways over the water ; the 

 same rule must be observed when leading a path through a 

 hedge or other enclosure. The outlines of shrubberies and 

 groups of trees must never be too formal or rounded ; a 

 slight irregularity will produce better effects of shade and 

 light and a more beautiful outline. Here and there stray 

 shrubs and trees should be planted to unite different groups 

 into larger masses, or to form specimens on the lawn. This 

 and like subjects will be more fully treated in subsequent 

 chapters.
