Abstract
Pieces of wood to be dried are stacked in an oven with a space provided between horizontal layers of the wood to permit air flow between the pieces of wood. Means providing the spacing are channel-shaped, non-moisture absorbing strips of metal or plastic approximately 3/4 inch square. The air for drying the wood will travel down the channel of the strips to help in the drying of the wood.
