PART VIII. PICTURESQUE PLANTING. 46/ 



deep, strong soil, as the oak ; some a dry, gravelly soil, as the 

 beech ; some a deep, moist soil, as the poplar ; others a peat- 

 earth soil, as the erica, &c. ; others, again, love a wet soil, as the 

 alder. Some trees will grow in almost any soil, as the Scotch 

 fir; others will scarcely grow in any but their natural soil, as 

 the rhododendron and the andromcda. Some hardly require 

 the aid of soil, as the ivy; others are parasites, as the 

 misletoe. 



15. The situations that trees naturally affect, are various. 

 Some will endure exposure of almost every kind, except a 

 strong sea breeze, as the larch, Scotch fir, and mountain ash ; 

 some endure the sea breeze much better than others, as the sy- 

 camore, ash, service, and elder; some will not prosper except 

 in a low, sheltered situation, as the black spruce, and most 

 American plants ; some will grow under the drip and shade of 

 others, as the Scotch elm, Norway maple, hemlock spruce, dog- 

 wood and box ; others would die in that situation, as the larch, 

 the pine, and the willow. 



16. Trees and shrubs, especially when young, require not 

 only a soil and situation, but a culture, suited to their-respec- 

 tive natures. Some require the earth to be frequently stirred 

 about their roots, as the lime and the lilac ; others will make 

 equal progress, if the surface be kept free of other vegetables,
