CHAPTER IV. 



Hardy Trees for Particular Purposes. 



The following lists of trees, largely native species, which are 

 adapted to particular uses in the north, is part of a catalogue pre- 

 pared in 1887 by L. H. Bailey. The trees are arranged somewhat in 

 the order of their merit. The species of each genus are strictly so 

 arranged so far as possible. 



I. Trees for Shelter Belts. 



White pine, Piniis Strobus. 

 Austrian pine, P. Austriaca. 

 Scotch pine, P. sylvestris. 

 Red pine, P. resinosa. 

 N'orway spruce, Picea excelsa. 

 Any of the rapidly growing, native forest trees, especially : 

 American elm, Ulmus Americana. 

 Sugar maple, Acer saccharinum and var. nigrum. 

 Basswood, Tilia Americana. 

 Cottonwood, Popuius monilifera. 

 Balsam poplar, P. bahamtfera. 

 Wild black cherry, Primus serotina. 



II. Trees for Groups or Single Specimens. 



A. Deciduous trees. 



Norway maple, Acer platanoides. 



One of the finest trees for single lawn specimens, especially in tranquil scenes. 

 It droops too much for roadside planting. 



Black sugar maple, A. saccharinum var. nigrum. 



Darker and softer in aspect than the ordinary sugar maple. 

 Sugar maple, A. saccharinum. 



This and the last are the best roadside trees. 

 Wier's cut-leaved silver maple, A. dasycarpum, hort. var. 



Light and graceful. Especially desirable for pleasure grounds.
