BLACK PINE. 



( P. Jeffreyi "Ores. Com." ) 



This tree bears a considecable resemblance to P. ponderosa., but favoi's a 

 drier climate, has a greater altitudinal range, longer foliage and larger 

 cones. The bark is also finer checked and darker, thus giving rise to the 

 common name "black " pine. Leaves, three in a fascicle, five to nine inches 

 long ; cones, large, six to ten inches long, producing a seed. 



Range — Lower California ( Mexico ) to Central Oregon. 



Use — Lumber, fuel, and pitch, the latter being used to a considerable 

 extent in medicine. 



TWISTED PINE OR WESTERN SCRUB PINE. 

 ( P. Contort a Loud. ) 



A typical coast tree, usually depressed and twisted by the coast gales, 

 thus accounting for the common names ''twisted"' pine, "scrub" pine. 

 Nevertheless, when it occurs in sheltered nooks in Oregon or Washington, 

 or in sphagnous marshes in South Alaska, where it is protected from the 

 winds, it is found to be a straight-grained tree, reaching seventy feet in 

 height, and serviceable for many economic purposes. It is closely allied to 

 P. Murrayana, but favors a much lower elevation, a moister climate, con- 

 tains more pitch, and has a much thicker bark than the latter. Leaves, two 

 in a fascicle, one and one-half to two and one-half inches long ; cones, one 

 to three inches long, producing a seed. 



Range — California to Southern Alaska, along the coast. 



Use — Farm purposes, fuel, etc. 



LODGEPOLE PINE. 

 (P. Murrayana "Oreg. Com.") 



A slender, graceful tree of middle elevations, ranging in altitude from 

 fifteen hundred to six thousand feet in tDregon and Washington. Attains a 

 height of sixtj' to one hundred and ten feet and a diameter of ten to twenty- 

 two inches. Largely used for fuel in some localities in Eastern Oregon, as 

 much as twenty thousand cords per annum being shipped from a single sta- 

 tion on the Oregon Railroad & Navigation Company's lines. The wood con- 

 tains less pitch and the bark is much thinner (one-quarter to one-half an 

 inch) than that of its near congener, P. contorta, the latter peculiarity lea%'^- 

 ing the tree an easy prey to forest fires. Leaves, two in a fascicle, one to two 

 inches long; cones, one and one-half to two and one-half inches long, pro- 

 ducing a seed. 



Range — California to Fort Selkirk, Yukon Territorj". north latitude 

 62°, 47'. 



Use — Farm buildings, fuel, etc. 



COULTER PINE. 

 (P. Coulter i Lamb.) 



A tree of medium height and limited range, apparently confined to the 

 Coast Range and San Bernardino Mountains. It is evidently barred on the 

 south by aridity and on the north by cold, and is noted for having the longest
