Jepson Field Book volume 18 page 40
Description:
Berkeley. Sept. 27, 1907  - W.W. Lyman Jr says: On the road over Spring Mountain from St. Helena to Santa Rosa at or near the foot of the graade on the western slope there are Redwoods and also Tan Oak. He says there is about 1000 cords of Tan Oak bark on his fathers place in Napa Valley. - Wagner at Briceland counts 2200 cords to ton of Tan Oak bark - Setchell borrowed my Howell's Flora and bringing it back said: "How little it represents Howell's work!" A very just observation -- and of course a pity. ::::::::: Benecia, Oct. 14, 1907.  - Kullman says: We are willing to pay more for the thick bark of the dry interior ridges than the thin bark of the deep Redwoods. I can tell where bark comes from when I see it. How thin will you accept bark? Depends on two factors: How thin it is and how much there is of it. We dont want a whole lot of thin bark, that is bark that is alike all the way through (in cross section). It hasn't any strength. We want a bark that shows three layers; ross or rough outside, central meat, and a part of the wood inside.  We don't use much quebracho. The quantity is negligible.
