SOME OF THE LEADING SHADE, LAWN, AND PARK 



TREES. 



307. Adapting Trees to Soil and Climate. — The nursery 

 catalognes of the Eastern, Southern, and West coast States 

 give lists of the leading trees, shrubs, and flowers, with 

 brief descriptions, but the planter is given no instruction, 

 as a rule, in the important work of adapting varieties and 

 species to a given soil and climate. To a great extent 

 this is true also of our works on landscape gardening. 

 Planters in the prairie States have had no guide except in 

 the horticultural reports and the fugitive notes in the 

 agricultural press. 



In this chapter only the leading varieties and species 

 will be noted that do well over large areas of the country 

 and on varied soils, adding a few specially desirable ones 

 that are less cosmopolitan. 



In many cases the same species differs in hardiness as 

 obtained in different parts of the Union. As well-known 

 examples, Picea pungens from the western slopes of the 

 Eocky Mountains will not survive the climate found east 

 of that range; the box elder and sugar maple of the 

 Eastern States will not live long west of the Great Lakes. 

 Indeed this varied hardiness of given species applies so
