The Pines. 323 



1312. The Pinon Pine {Pinus edvlis). This abounds in the 

 mountains of Arizona and New Mexico, occupying the lower ridges 

 and the swells of land on the "divides" between the headwaters of 

 these regions. The seeds are sweetish and edible, when roasted, and 

 are kept for sale in the markets. The. tree itself is of a crabbed 

 shrubby growth, spreading out like an old neglected apple tree, 

 and usually does not grow more than 25 to 30 feet high. The 

 wood is excellent for fuel; but too small and poor for lumber or 

 other uses. 



1313. One-Lea VEB Pine (Pinus monophylla). This occurs as a 

 low tree, from 20 to 25 feet high, with- an open rigid habit, and 

 branches spreading or sub-deflexed. It grows from the eastern 

 slope of the Sierras, and from thence eastward, in Nevada, Ar- 

 izona, and Utah. It also occurs in Oregon, at an elevation of 

 from 4,500 to 5,000 feet above tide. It has large edible seeds, 

 and is nearly allied to the pinon pine of Southern Colorado and 

 New Mexico. From the Sierras to the Wahsatch, this pine occurs 

 scattered over the dry slopes, and seldom more than 15 feet in 

 height'. 



1314. Pinus Balfouriana. This is a middle-sized tree, growing 

 in Northern California and on the summits of the mountains east 

 of the Humboldt range, in Nevada. 



1315. The Norway oe Eed Pine (Pinus resinosa). This is a 

 northern species, growing in Canada and New Brunswick, and along 

 the northern border of the United States, from Maine to Minnesota. 

 It does not generally form large bodies of timber, but occurs in de- 

 tached clumps. The wood is coarser than that of the white pine, 

 but is stronger, and much used for bridges and other timbers, where 

 strength and elasticity are required. It grows to the height of sixty 

 to seventy feet. 



1316. The Pinus Torreyana is a small tree on the southern 

 coast of California, bearing large, thick, heavy cones with edible 

 seeds. 



1317. The Pinus Arizoniea grows on the Santa Rita Mountains in 

 Arizona, and is nearly related to the following species : 



1318. The Heavy or Western Yellow Pine (Pinus ponderosa). 

 This species is widely scattered throughout the Rocky Mountain 

 region, in the "Western Territories, and the Pacific States. It
