When the saw isdrawn back, the more sloping side of the teeth has very littleeffect upon the fibres, and the saw goes empty. The teeth of the bow-sawfor cross cutting form an isos-celes triangle of 50° betweenthe teeth. A saw of thisdescription cuts equally wellbackwards or forwardsThe space between the teeth must be great enough to leaveroom for the sawdust until the saw has carried the latterbeyond the wood. Now, as the sawdust occupies morespace than the wood from which it is produced, the teethof the saw must be considerably longer than the depth of thecut made eac
