tapering tree is yet another ; three Macedonian Pines in a triangle 

 here. The two front ones are rather similar to the Swiss Stone- 

 Pine just back to the left. But if we look carefully at the young 

 branchlets near their tips we will see that those of the Stone-Pine 

 are very distinctly hairy while those of the Macedonian Pines are 

 smooth and yellowish. It is well to notice here that dust and dirt 

 accumulates on these otherwise smooth surfaces and may appear 

 as a fine hairiness. However, these three trees will very quickly 

 show the difference between genuine hairiness and what may 

 merely appear as such. 



Farther along the path, we notice a large boulder half buried 

 in the ground. By it stands another Himalayan White-Pine and 

 two more trees of the same kind are in the nearby vicinity. One 

 is the large tree farther up the slope and a bit to the right and 

 the last one is farther along the path, betrayed by its long foliage. 

 There is one more tree right here just before we get to this last 

 Himalayan White-Pine. It stands at the same distance from the 

 path and is a Korean Pine (p. 42). Moving on a bit, we come 

 to an opening in the planting and the low dense evergreen half 

 way up the slope is a Macedonian Pine. 



Following the path now to the left, we pass four larger trees 

 that we recognize as Austrian Pines. 



The remaining four small evergreens near the last Austrian 

 Pine are 



Pinus edulis, the Nut or Pinon Pine 



This tree so far is unimportant ornamentally in this section of 

 the country. It is native to the Rocky Mountain regions at eleva- 

 tions up to 11,000 feet in New Mexico, Colorado, Utah, Arizona, 

 and northern Mexico. The Nut Pine is normally of small stature, 

 not more than 30 or 40 feet in height and its scraggly and stunted 

 form on dry and gravelly uplands of the Southwest is one of the 

 characteristic marks of that region. 



The leaves on the Nut Pine vary in number, occurring singly 

 or in threes, but usually paired. The wood is highly esteemed for 

 fuel and railroad-ties, but otherwise has little value. The seeds,
