 PART 2— PINES 



THE WORLD'S GREAT TIMBER TREES 

 VALUABLE LARGE ORNAMENTAL EVERGREENS 



Section 1 



Section 1 of the Pines is that portion of the Pinetum, not in- 

 cluding the Maidenhair Trees, that horders the Central Drive on 

 its eastern side from the Southern Boulevard entrance to a point 

 opposite the Museum. It begins with the first evergreens near 

 the last of the Ginkgos. (Map p. 7). 



In order to view these first pines, let us stand on the highest 

 point of the rocky formation that lies at the north end of the 

 Ginkgos and at the beginning of the Pines. 



The three similarly shaped trees to the extreme left are 



Pinus Cembra, the Swiss Stone-Pine 



.Omitting the next taller tree to the right, the seven similar 

 compact trees nearest the foot of the rocks more to the right are 

 also Swiss Stone-Pines. Most prominently we notice the very 

 compact, symmetrical, and rounded-pyramidal contour of these 

 trees, a very pleasing feature that makes them highly desirable for 

 ornamental use. It is a youthful shape assumed in cultivation, 

 whereas, naturally, older trees are of taller and less compact habit. 

 They are exceedingly hardy and slow of growth. 



The Swiss Stone-Pine or, as it is sometimes called, the Arolla 

 or Alpine Pine, has a very extended natural range. It is found 

 in the central European Alps from Savoy to the Carpathians, and 

 in northeastern Russia and northern Asia. In the valleys of the 

 higher Alps it is the only tree capable of withstanding the eleva- 

 tion and intense cold. Herdsmen, as a result, have destroyed whole 

 forests of these trees for firewood and today they no longer are so 

 abundant as formerly. However, they still cover immense tracts 

 of country in Siberia, Tartary, Italy, and Switzerland, reaching 

 to an altitude of 6,000 feet in the Alps. In Siberia they become 

 a dwarfed variety, pumila, and extend as far east as northern 

 Nippon and Kamschatka.
