Large pieces crack more than smaller ones, quartered lumber less than that sawed through and through, thin pieces, especially veneers, less than thicker boards.
In order to prevent cracks at the ends of boards, small straps of wood may be nailed on them or they may be painted.

This method is usually considered too expensive, except in the case of valuable material.

Squares used for shuttles, furniture, gun-stocks, and tool handles should always be protected at the ends.

One of the best means is to dip them into melted paraffine, which seals the ends and prevents loss of moisture there.

Another method is to glue paper on the ends.
