A method for treating a wood piece to be dried. The wood piece comprises a complete cross-section through a tree trunk or branch and includes bark, phloem tissue, xylem tissue and heartwood and is commonly referred to as a pole. The method involves passing an electric current through the length of the wood piece for a pre-determined period and removing the bark immediately before or after the electric current treatment so that the tendency for the wood piece to split or check during subsequent air drying is reduced. The method is particularly useful for treating pine or spruce poles intended for carving into walking sticks or turning on a lathe.
