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.
