SHADE, LAWK, AND PARK TREES. 34? 



leaves are not suitable for small places. But it is one of the 

 best for parks and large places. The stone pine (Pinus 

 cembra) from the plains of east Europe is hardy anywhere 

 in the East or West. It is much like our white pine in 

 shade of color of foliage, but it is far more compact in 

 form and is pyramidal in habit. As obtained from west 

 Europe it is not hardy at the West. 



The type of Scotch pine (P. sylvestris) from east 

 Europe known as Eiga pine is hardy at the West, and is 

 more ornamental east of the lakes than the trees grown 

 from seed gathered on the sandy tracts of Alsace, France. 

 Its bluish shade of color of foliage fits it for planting at 

 points to which attention is to be directed. 



The Swiss mountain pine {Pinus montana) is extremely 

 variable in habit. The most valuable type at the West is 

 P. pumilio. It is a handsome low-spreading shrub, with 

 dark-green foliage that varies little in color in the drought 

 of summer or the cold of winter. It is specially valuable 

 for corners and angles of lawns, walks, and drives. Several 

 other varieties of varying heights and habits of growth are 

 valuable east of the lakes. 



330a. The Hemlock. The hemlock (Tsuga Canadensis) 

 is also variable in its adaptation to varied climates and soils. 

 As obtained in northwestern Wisconsin it has proven hardy 

 and very beautiful in the prairie States in situations where 

 sheltered from the westerly winds, while plants from west- 

 ern New York have been withered during the first year of 

 growth. The Northwest type also endures drought on high 

 ground, while the Eastern type only succeeds on moist 

 ground. The hardy type is admirably suited for orna- 

 mental screens, and can also be used to advantage as single 

 specimens. 



330b. Arbor Vitse. The American arbor vitse (Tfiuya 

 accident alix) is admired in landscape work when young,
