These books are a nice early presentation of wood puzzles and their construction, including the Missing T ("Cut-Up T"), Tangram ("Cut-Up Square), a version of Iribako ("Bewitching Cubes"), Fifteen ("Shuffle Puzzle 1"), Dad's Puzzler ("Shuffle Puzzle 2"), a version of the Checkerboard Puzzle, ("Cut-Up Checkerboard), Towers of Hanoi Towers Of Hanoi ("Peg And Disc Puzzle"), Wood Knot ("Three Piece Cross"), simple 6-Piece Burrs, and a number of other burrs. Both books have been printed many times (when Wonders in Wood was published, Puzzles in Wood was in its eighth printing); here are 2007 editions:
