These opera- tions may be divided into the following branches: handling the logs; sawing; trimming and sizing; disposing of refuse; sorting; storing or shipping. In order that the sawmill operator may more profitably dispose of his better grade stock, a finishing mill is a necessity and in reality such a more or less completely equipped mill is always understood to be included in the general term "; The operations are so distinct, however, that it has been thought best to include the planing mill under a separate heading. In those mills which finish a large portion of their product, there is between the sawmill and planing mill a seasoning process, which * Reproduced by courtesy of the American Institute of Electrical Engineers- Continued from March 15, Canada Lumberman. we will term "; This consists of artificially drying the pro- duct before finishing it. Its object is to get the material to its ulti- mate seasoned dimensions before the final manufacturing operation.
