YELLOW PINE. BULL PINE. 



Interior of British Columbia, south of latitude 51, south and east along the mountain ranges of the Pacific 

 region to Mexico, the Black hills of Dakota, Colorado, and western Texas ; not detected in central or southern Nevada. 



A large tree, 61 to 91 meters in height, with a trunk 3.60 to 4.57 meters in diameter, or throughout the Eocky 

 Mountain region much smaller, rarely exceeding 30 meters in height (var. scopulorum) ; dry, rocky ridges and 

 prairies, or in northern California rarely in cold, wet swamps, reaching its greatest development along the western 

 slope of the sierras of northern and central California; in western Washington territory and Oregon rare and 

 local; after Pseudotsuga Bouglasii the most generally distributed and valuable timber tree of the Pacific forests, 

 furnishing the principal lumber of eastern Washington territory and Oregon, western Montana, Idaho, the Black 

 hills of Dakota, western Texas, New Mexico, and Arizona. 



Wood, varying greatly in quality and value, heavy, hard, strong, brittle, not coarse-grained nor durable, 

 compact; bands of small summer cells broad or narrow, very resinous, conspicuous, resin passages few, pmall; 

 medullary rays numerous, obscure ; color, light red, the very thick sap-wood almost white ; specific gravity, 0.4716 ; 

 ash, 0.35 ; largely manufactured into lumber, and used for railway ties, fuel, etc. 



Note. A form with purple cones and long glaucous foliage, approaching P. Jeffreyi in habit, is the prevailing tree of the valley of 

 Flathead lake, Montana {Canby ^Sargent).

BULL PINE. BLACK PINE. 



California, Scott's mountain, Siskiyou county, south along the Sierra Nevada to the San Bernardino and San 

 Jacinto mountains. 



A large tree, 30 to 31 meters in height, with a trunk 1.20 to 4 meters in diameter; dry, gravelly slopes between 

 6,000 and 8,000 feet elevation ; most common and reaching its greatest development on the eastern slope of the Sierra 

 Nevadas, here generally replacing the allied P. ponderosa, from which it may be distinguished by its more deeply- 

 cleft bark, glaucous branchleta and leaves, much Jarger cones, and by the strong, pungent odor of oil of orange 

 of the freshl.ycut branchlets.
