The sawing of an elongated workpiece, such as a log or cant, by feeding the workpiece longitudinally through a saw; sensing the longitudinal configuration of a longitudinal side surface of the workpiece on one side only of the workpiece as the latter passes through the saw; and orientating the workpiece relative to the saw in accordance with the sensed configuration to saw the workpiece longitudinally substantially parallel to the sensed configuration. For the sawing of a crooked workpiece, the configuration of a longitudinally extending concave side surface is sensed and the workpiece is sawn "round the curve" substantially parallel to the sensed concave configuration the workpiece is orientated by resiliently exerting lateral pressure thereon on the side thereof on which the longitudinal configuration is sensed. The invention covers the method of sawing workpieces, as well as apparatus for sawing and for controlling the sawing process.
