Genus Pinus. 
P. monticola Dougl.: Western White Pine. This tree is found on the 
western slopes of the Olympics, above 500 feet elevation, usually in swamps 
and wet places. 
Description: Cones oblong-cylindrical; scales of cones unarmed; leaves 
five in each fascicle. 
Genus Abies. 
A. nobilis Lindl.: Lovely Fir; Noble Fir. This tree is found at consider- 
able elevations; but rarely at elevations less than 1,500 feet. 
Description: This is a tall, silvery-barked, noble-looking tree. It differs 
from the other firs principally in the color of its bark and in its having cones 
with conspicuous reflexed bracts. 
A. lasiocarpa (Hook) Nutt.: Alpine Fir; Subalpme Fir. This tree is found 
only on the higher parts of the mountains, rarely below 5,000 feet. 
Description: A tree of 60 to 80 feet in height; bark pale, thin, smooth, 
ash-gray in color; leaves dark-green above, with two resin-ducts about 
equi-distant between the upper and lower face; cones oblong-cylindriecal, 
puberulent, with bracts concealed. 
A. amabilis (Doug].) Forbs.: Lovely Fir; Amabilis Fir. This tree is found 
only on the high ridges adjacent to the mountains, rarely below 1,200 feet 
elevation. It is one of the large lumber-producing trees of the region, pro- 
ducing more than 11,000,000 M. feet B. M. 
Description: This tree is distinguishable from A. lasiocarpa above by its 
cones not being puberulent and by the greater length of the cones. 
A. grandis Lindl.: White Fir. This tree is occasionally met with in the 
Soleduck Hot Spring region. 
Genus Pseudotsuga. 
P. mucronata (Raf.) Sudw.: Douglas Fir; Red Fir. This tree grows in 
abundance. It reaches its greatest development in the Quillayute-middle- 
upland region. In its growth, however, it extends up the mountain slopes 
to the altitude of 3,500 feet. In the high mountains and in the neighborhood 
of the Pacific coast, this species is practically entirely wanting. It grows 
to its greatest dimensions where the stand is heaviest. Throughout the 
region it averages 240 feet in height; 77 feet clear of limbs, with a diameter
