Wood is frequently used in the original round form rather than in the form of sawed products of the log, such as boards, planks, and timbers, or in the turned form, such as dowels or table legs. The round item may be large logs of historical interest, logs for cabins, material for constructing rustic furniture, or sections of tree trunks or limbs for exhibits or novelties. It is essential that many of these items be seasoned to a moisture content consistent with service conditions, and that the bark be retained. The seasoning should be accomplished with a minimum of deterioration through checking, cracking, and fungus and insect attack.
