FOREST TREES OF THE PACIFIC SLOPE. 193 Longevity,—Veiy little is known of tlie age, but it is believed to be a long-lived tree. It appears to grow persistently, but very slowly, in height and diam-eter, as shown by its small size. Trunks from 4 to 8 inches in diameter arefrom 60 to 110 years old, and those from 12 to 18 inches through are from 170to 205 years old. Further study of its growth and age is required. Central California, on coast ranges and west slope of Sierras.
