Seed-leaves, one-third to one-half inch long, usually 4. Wood, fine-grained, light, soft, and from pale straw color to light yellowishbrown. Little clear timber is obtainable because the trunks so often retainbranches down to the ground. It is fairly straight-grained and splits and works.

Longevity.—Probably not a long-lived tree. Much more study of its age isrequired. Trees from 12 to 20 inches in diameter are from 140 to 210 yearsold. The considerably larger trees which occur are not likely to be more than250 years old. 15188—08 8 110 FOREST TREES OF THE PACIFIC SLOPE. RANGE.
