PROBLEM TO BE SOLVED: To provide a simple and easy means for preventing dry cracks due to natural drying by saturating the interior of a cap with water content vaporized from the butt end of wood, restraining the vaporization of the water content from the surface of the wood from the bag mouth of a cap to the butt end of the wood, when a non-eleaved wood with a core of a Japanese cypress, a Japanese cedar or the like is dried. SOLUTION: In order to prevent the vaporization of moisture content from the butt end of wood, a bag-shaped cap which has a bore complying with the dimensional shape of the section of the butt end of the wood, and is made of polyethylene or the like, and moisture impermeable, is fitted to both butt ends of the wood. Further, in order to bring the bag mouth of the cap into close contact with the surface of the wood, an elastic rubber band is previously fitted integrally into the bag mouth of the cap, so that the cap may be attached and detached by one touch of finger.
