Title:
Jepson Field Book volume 10 page 84
Description:
Briceland  - Douglas Spruce bark -- 6 1/2 in thick at 4 ft. from ground.  - Conclusions  Expert peelers should be employed  Peeling by contract is wasteful  Trees should never be peeled standing  - Trail builders -- surface leaves and humus must be cleared off. A broad edged pick is used. The mules otherwise -- loaded heavily -- would slip and not be able to get up again. :::::::::  June 18, 1903  [Tan Oak.]  - A tree 1 ft. diam = 80 years - "  "  1 1/2  "  = 90  " - "  "  10 in.  "  = 75  "  bark 1-1 1/4 in thick at 1 ft. - "  "  10 1/2 " "  = 90 years; is 74 ft. h. & was peeled 24    ft. - Any number of trees 10 in. diam and 50-70 ft h. with 1 or 2 rims taken, the abandoned lowest bark being nearly or quite 1 in. thick.  - "Live Oak" here means Maul Oak as indeed it does, I presume,  everywhere throughout the Tan Oak belt. - Black Oaks and Garry Oaks often send down long horizontal or declining branches conforming to the shape of the hill slope they inhabit.
