A superb book for wood craftsmen about wood, not woodworking. The author teaches wood technology, contributes to Fine Woodworking magazine, and has been carving the stuff since he was a kid. He has done a painstaking job of making accessible a lot of essential but technical information about what wood is (from cells on up) and why it acts as it does. It’s the difference between knowing that a board can check and warp, and knowing why. The photos, captions, and design are equal to the fine text.
