TREES 



and to furnish shade and shelter. The enjoyment the 

 trees give by beautiful flowers, various foliage, splendid 

 autumnal tints, and ornamental fruit is more incidental, 

 though of great value and worthy of careful considera- 

 tion. The trees should be selected for planting in ac- 

 cordance with the natural and intended character of the 

 scenery and not be taken indiscriminately because they 

 happen to be handy and easy to procure. 



It is essential that the trees should be well adapted 

 to the climate and soil, and in this respect a careful 

 observation of the natural tree growth of the locality 

 will give many good hints. Other considerations are the 

 height the trees attain, the character of growth, color 

 and effect of foliage, flowers and fruits, autumnal tints 

 and winter eifects. Concerning the general rules which 

 govern the selection of trees for planting and which are 

 principally the same as in herbs and shrubs, much 

 other information may also be found in the articles on 

 Landscape Gardening, Park, Shrubbery and Serbs.
